I have searched, and have not found any information that can help me.
I have a touch that the Service Centre want £90 to repair - new motherboard. Is this fixable with a jtag - If so, does the Holly Gates Schematics for a Jtag Dongle work here?
Has anyone successfully JTAG'd an ELF? If so, was it due to a similar circumstance as myself?
Anything I have come across goes to Russian sites - I'm not russian, nor can I read it.
I have seen posts for other devices, but these seem to all be based on a Samsung Chipset, apposed to our OMAP devices?
Any help would be great, even if it is just to go read a post that I have missed when searching.
Stu
Hey, not sure if anyone would care all to much.
I have found a jtag setup I am curently preparing to use, I am going to hopefully be trying to do this tomorrow. I am working on a guide as I do it - as I haven't been able to find one. If this would be useful to anyone let me know, and I will upload it as soon as I have tested it on my broken elfin to make sure it works!
Hey mate, we care and keep us posted with any results.
Good luck!
hey just come into a bit of a stuck point. I have no images to support this.
I am trying to fix the cables to the main board on the jtag points. Aout 5mm wide. I dont really want to solder them on. Does anyone have any suggestions on how best to affix them? I'll try and get some pictures up tomorrow when i can.
Stu
Unable to do pictures today, I will do them tomorrow hopefully on my lunch break, so people can make suggestions.
I am a little scpetical about if this will work. I do not know the history of the device I am tinkering with, but I hope this will fix it.
If anyone has a broken elf they would like to part with for me to test, that would be great (I would pay ofc)

Hey,
Please see attached image.
This points out the JTAG test points, labelled to what they do (in theory) and what pin they connect to the JTAG device from the LPT cable.
I think these are very small to be able to tape them on, I also do not think that they would give a good enough connection. I am going to try to solder the cables on tonight - but in the mean time, if anyone has any suggestions, please feel free to let me know. Any ideas are good!

Hi captainstu72,
I have a completely dead HTC Touch P3450. Really dead. Even when I plug the charger to the device, the orange light (as a sign that the phone is charging now) can not light on.
A service man asked me to replace the machine for USD 80, as he said we can not do j-tag to HTC ELF
Your thread is very exciting. Please keep posting, I'll follow this thread.
Thanks

Hey bombom81,
I'm glad this can be useful for others. I just want to make sure that people don't get their hopes up too soon, thats the thing, I don't know if it is definately able to work, but I know it has been done on other phones with a very similar chipset to ours.
If I have any major break through tonight, I will definately be doing a write up on it tomorrow in my lunch, and If you'd like I can PM you when done so you can give it ago.
Your ELF sounds as though it is in a similar state to mine, so hopefully, if I get this fixed, it may well work on yours!

Yes..I had this problem months ago and I've made a thread for it :
http://forum.xda-developers.com/showthread.php?t=582913
Unfortunately, every suggestions I got from people here didn't work in my device. And I could not even claim a warranty for it as the seller said that the product warranty is already expired too long ago (in the end I knew that the product was his present from his office, and when he said it is new, means that, It is new because He never used it...LOL, not "new" from the factory). So I just keep it in my cupboard.
I think It will be more valuable for others if we discuss here, on your thread, than PM, as I think there are many people are having the same problem like us (as many as I can find after I google "Repair Totally Dead ELF" )
Please, kindly also check this thread : http://forum.xda-developers.com/showthread.php?t=602233
This guy also found a similar thing like yours. I actually don't know a thing about JTAG. In the future, please forgive me if I might ask you some questions about it and I hope you don't mind about my questions.
Thanks for your kind to share your experience with us, I'll keep watching this thread and hopefully you'll be success with your experiment so it can bring the joy for all of us.

Hey,
Likewise, every suggestion I could find had no luck, which I why I decided to dig deeper.
I did come across GallegoT's thread, however, I sent him a PM to see if he had got anything sorted, but I have never heard back - So I created a new one.
I was going to keep this thread posted, don't worry, I was only going to PM you when it was finished - to save you keep checking it
Had a few issues with it last night, tried soldering to the board, but my soldering iron doesn't get hot enough, hasn't got a thin enough tip, and my hands weren't steady enough - Also the wires I was using were fairly wide, I have swapped these for a thinner Kynar wire, and will more then likely be remaking the whole of my setup to make it easier.
Just so you have an idea - I currently have an LPT (male to male) cable which I have taken the end off, and soldered wires to 2 3 4 6 11 and 18-25. 18-25 link then into one wire, as this is to ground the device. 2 3 4 6 and 11 are connected to 100Ω resistors each. These are then connected to wires, which are ready to be connected to the device.
Thats the basics of the device - I do not have an image of what I have planned out avaliable, but you can get the idea of it from what is in this post, and using my image posted earlier.
Maybe you guys have better tools - soldering equipment etc then I do.
When this is done you need to run a program called HJtag, and NoIce. I have an idea on what to do for these, however, I have not tested it yet to want to post it on here.
Like I have said though, I will be making a guide that is as full as I can.
I will try some more tonight, to get the cables connected, and hopefully then will be able to give the whole process a go.
Thanks for your interest in this thread, even if I only manage to help one person, at least then I feel as though I will be giving something back to the community on this site.
(I'll point out now - I did not have a clue about Jtag before now - but I also have some links I will post which make some interesting reading!)
Stu
Hey to anyone who is still watching this.
I have just got my elfin all wired up, ready to go, circuit is fully continuous and there are no bridges (I haven't soldered for more then 8 years!)
However, I have been a bit stupid, my pc doesn't have a parallel port. I'm going to buy one tomorrow and get going - very annoyed about this set back, i'm such an idiot for not checking!
I'll try it tomorrow night hopefully, worst case would be friday/saturday - A long time since starting this projct, but my hopes are high and I really hope I can help some of you guys out there!
Just thought I should update you all, I don't want this thread to become dead... like our elfs
Stu
LOL..no need to worry that your thread is dead.
I'll visit this thread everyday to see how it's going
BTW...do we really need the LPT Socket to do the JTAG? if so, then I will have to ask my IT man in my company to find me a "no-used" LPT socket, lucky I have an old Pentium 3 PC that I might be able to use it for this JTAG matter.
Please update the step-by-step tutorial here with photos so I can follow you easily. FYI, I am blind in this JTAG matter, so please do not mind to answer my next "silly questions".
Keep going! Thanks
Parallel is the only interface I have found to do it on - I would have much prefered usb or something more up to date, but we can't always have what we want.
Below are a few links that I read through before doing anything, just so I could get a vague understanding. I'm workign on the guide today on my lunch - the last part will have to be in theory.
Jtag Introduction
Someone Jtag'd an Ipaq (not the same but the concept)
Has some links to JTAG
Program we will be using for the jtag
NoIceDebugger - A program I will be using
What I think our Processor is
OMAP 850
Again, I will be making a an actual guide, this is just some reading before hand that i did that may be useful!
Stu
hey, well, i have a parallel port and have attempted the jtag.
It didn't work.
My guess is i was using too long cables, or something has come loose. My continuity tester has now died so i will be testing again on the weekend.
I'm going to post the guide i am working and what i did tomorrow. Maybe someone (bom81) would be able to give it a go and do well as i'm sure he will.
Sorry for the failure, but i am really optimistic that it will work, and that it didn't only because of something i may have wired wrong that someone else does right. I'm going to try and get a thirc elf to break and fix as well as it may just be the one i am doing is beyond repair.
Bom81, if you give this a go, good luck. I'm sure you'll have some luck!
If anyone else tries when i have the guide up, please please let this thread know, even if it doesn't work.
Stu
Hi Stu..
Can you give me the russian forum that explain about this jtag on HTC Touch.
I'm going to learn it there.
BTW, how long have you made the cable? have you cut it shorter and try again the connection?
Try to read this thread : http://forum.gsmhosting.com/vbb/f98/htc-elf-dead-after-wrting-elfin-rom-650359/
This guy has the same problem with us but finally (or luckily?), the device could come to Bootloader mode. I'm going to try to PM him, so he can explain how did he get the device work.
Thanks for your try.
Regards,
Bom81
This is for the wizard - same omap 850 http://pda2u.ru/forum/index.php?showtopic=348
I can't find my link for the touch, it may be on my home pc, but it was on the same website iirc.
Cable was about 50cm's - Too long, so I am remaking it to around 15cms tonight, but will be fun as I do not have my continuity tester to make sure that the circuit has the right resistance etc. before I think I was going over by too much due to cable length.
I have started the guide, I just need a few files off my home PC, so I will do this tonight again.
It really annoys me when other threads/sites do not put everything down they have tried, the internet is for information, not for saying, "ha, i've done it!"
I'll try again tonight and tomorrow, I think I have my LPT PCB sockets waiting to be collected, all the way from China, so this will be easier for me to do ultimately.
I haven't yet given up hope, and I'm sure that if I get my document made, someone will be able to tweak it and further help us.
I just don't know how many people are using the Elf's anymore, its fine there being a thread saying we have 900's htc touch's, but how many still use them and are active on this community.... but I digress.
I am really sorry that I am not good in Electronic thing, nor that I know how the electronic equipment works.
But I will try to learn from the website url you provided. Afterall, my HTC is already dead, it will not be a big problem if I make some experiments on it. If I'm lucky enough, I might wake a Frankenstein from his dead. LOL !!
Thanks,
Bom81
JTAG HTC device
Thanks first of all for your effort captainstu72 and bombom81, very interesting thread.
I am also in the same situation - having a bricked device (flashed wrong ROM and/or wrong carrier) and thus also interested in getting a serial cable hooked up to it no bootloader - no reset. The device is therefore software-wise dead.
I would therefore also love to try your procedure to getting a JTAG connection to the device. I have not been dealing with soldering on electronic devices since I did this on commodore 64... quite a few years ago as you imagine but therefore even more exciting.
I will check this thread and get a serial cable. Oh does the H-JTAG Software also run from linux since I only work on linux on this machine?
Thanks in advance and let me know if I can be of any help in this.

Hi Stu and ITCons (welcome to the thread)
I've read the Russian website and have made a translation of the thread from Russian to English using Google Traslate.
Unfortunately, as I said before, I have no competency in electronic, but I'll try to learn.
All credits for the compiled document will go to user id : MEDUSH and ARCC in the Russian Forum (PDA2U.Ru), as they mentioned this document might be reprinted by their copyright.
Please have a read to the document I attached...I'll come back if I'm finding out something (as this week I'll face my busiest week of the month, there are some reports in my daily jobs that I need to prepare to my Boss...LOL).
Thanks for your kind attention.

Bom81
Thank you very much Bom81
I have found another thread on this forum as well in the gene section, which shows how they did it on the gene too (omap 850 processor as well) I have posted on there to ask if anyone can relink to the revised download, but so far, there has been no update.
I'm going to go through what you have posted tonight bom, it matches most of what I was going which is always good (from my point of view, as it means i wasn't chasing a lost cause)
Sorry for not posting the guide yet, i'm slacking! But now, obviously, it does not matter so much as bom has posted an excellent guide in his post.
ITcons - I have had a (very) quick look, I don't think HJTAG runs on linux, although I would be interested to see how it would work in cedega/wine (this is not something I can test personally), I hope it would be able to use the LPT ports etc correctly - but again, nothing I really have a whole lot of experience about.
I'll see how it goes tonight, hopefully I should have remade my circuit again, and will be ready to test once more! - This time I am using an LPT PCB Socket - hopefully easier to do as there will be less in the way of resistance from excess cables.

Hello all, I am looking for a small group of developers looking to make an opensource port for the HP touchpad. I currently have an android tablet, and I'm looking to port android to this cheap yet powerful(debatable) tablet!
add me on skype: Rockinoutt93
look forward to working with you guys/Gals!
make it happen!
there is already a thread discussing this
Join the group from above, the more smart people working on this the better for the community. There will be some nice rewards for you if you are able to port it first and by yourself though....
will see what I can do =3
well based on the community gathering here im gonna go buy one at 99 bones i cant really go wrong.
The TouchPad is the new HD2

For $99, even if it has no apps to download it's still a good deal. Much better than many of the nameless single-core Froyo Android tablets selling at your local pharmacy. None of those is as cheap as $99 btw.
I haven't been developing for very long, and am still learning, but I am willing to help with this project to the best of my abilities. I am also willing to donate to those who help this project become a reality.
I love you guys!!!!!
Best $99 ever spent
-andrewxu :l
I just bought a couple 32gb TouchPads. Let me know how I can help!
I cannot post a link but there is a group of people working on this project over on rootzwiki. Might be nice if everyone got together.. Or possible had a race
Rumor also has it that the dev team over ay Cyanogen is working on developing a port for this as well. So there is definitely a lot of interest in this. There are even some dev teams that are trying to get Ubuntu/Linux to run as well.
I think that since someone was able to run gingerbread on the Pre that this should be something that someone could pull off. We will just have to keep supporting the developers and this will be an amazing accomplishment.

Let me know where to donate.
I lol'd at the "The TouchPad is the new HD2." Luckily, I have both now.
Also, I think the new name for the TouchPad should be the LootPad. I'm not sure how your guys' experiences were at where you bought it but it felt like a moment of panic on the Titanic as it was sinking.
I hope this thread will remain on-track with discussions of porting Android. The other thread started on that topic is a total mess now, as 95% of the 34 pages are about where to buy the touchpad now.
Very interested in following a genuine discussion on an Android port. I have an HD2 and can't believe how perfect the CM7 (and earlier Froyo) port is. You can't even tell it was ever a WM 6.5 phone.
This is already going on at Touchdroid. Might be a good idea to copy and paste their progress here. They only ask that if you're not deving, don't post, they have a lot going on. Link to thread below

I bought a g2x used with 2.3.3 and I love it except the battery life. I heard that if I downloaded the 2.3.7 the battery problem would go away. My problem is that I know nothing about this type of "stuff" but I'm VERY excited about learning and starting new and TRUE relationships with other members. PLEASE HELP me get this LG g2x straightened out.: I need to learn how to re-root this phone. I have to make4 sure that I don't harm what good I already have. If I can't get better battery life from this phone I will have wasted $250. I just finished "fighting" Lymphoma cancer and I can't afford to throw away money, especially in these amounts. Please help me and get to know me and I the same with you.

Hello sir. All you have to do NVFlash CWM and you're all set to flash a ROM.
Follow this video: http://www.youtube.com/watch?v=Cy9on64jAZs
Just the part where you do the NVFLash. Once that's done upgrade CWM to the latest version, you can find that in the dev section.
Then you just simply DL CM7, wipe your phone then flash your desired ROM.
I didn't really go into details in case you're already familiar with CWM and flashing, that's just a gist of it. But if you need more help and have no idea what flashing and CWM is then let me know.
GREAT to hear from you.
Howd ya know? I have no idea what CWM or flashing is! I want to thank you for writing back to me. I'm MORE than excited about talking with the members of this site. I'm having dental work done at the University of Washington school of dentistry and I have to go to bed since I have to get up at 6:30 in order to make it to Seattle from Olympia by 9:30. I hope tomorrow we can continue to talk about these and other issues with these type of devices? Thank You....who are you? I want to learn how to attach a video to my post like you did for me. You have no idea how excited I'm about this site and talking with you guys. The member that just answered my question is totally freaking me out with the knowledge that you have about my phone. What I think your saying is that I need to get a cord that goes from my power outlet on my phone to a usb plug on my computer? Please explain, in detail, what you mean when you say " All you have to do NVFlash CWM and you're all set to flash a ROM." Is that where I empty my phone and then re-load with an updated version? Do I have to protect my phone? Did this phone come with 2.2.3? What do the numbers mean? I hope I can help you with something in return? Thank you VERY MUCH Sir. I look forward to talking with you tomorrow...cgarland
Is this g2x a good phone if I can get the battery to last at least one full day? I like the phone and all that I've read about it (except the bad) but it is my first smartphone. Seriously mackster248 I want to keep this phone. Can I make this phone work properly so I will be happy with it? Will the battery life improve with updates? What is "ROM: CM7 or MIUI" I'm not kidding, there is a guy on Craigslist that did exactly the same thing to his g2x, that is he has CM7 and MIUI on his g2x. Here is his post. What do you think mackster248?
Title says it all, unlocked for any GSM carrier and rooted with cyanogen mod 7 and flashed with a cool MIUI rom making it faster and better looking than ever.
Will come with HDMI cable, black hard rubber case, 2 chargers and original box. 9/10 condition front and back it had a screen protector on but I recently took it off because it made the phone look like crap. It has a CLEAN front now.
MOSTLY LOOKING FOR TRADES but $275 cash nothing more nothing less is good. Looking for an iPhone 4 unlocked I dont care how many gbs just has to be unlocked, same condition, with charger at least.
Looking for:
Iphone 3gs 16/32 gb unlocked and jailbroken w/ accessories and some cash on your side.
LG thrill unlocked
Iphone 4 unlocked
HTC sensation
All offers are considered just shoot me what phone you have.
206 four53 eight713 will send pics through text!
Teach me what it is you both are talking about mackster....PLEASE! See that where he say's what you said?
Thank You, cgarland
i have a problem as host's, it's very helpful, thanks
Well CWM is a recovery that's needed to flash custom ROMs. You need to follow that video to install CWM via NVFlash. Just do that portion first then I can help you with the rest.
Sent from my LG-P999 using xda premium
Cwm is clockwork mod recovery.. it is a modified recovery that allows any rom to be flashed to your phone.
Recovery is a utility built into the phone that lets you do various tasks like install different modified versions of android reset your phone to a "new" state... deleting all the data on it (except android itself)
To flash a rom means to install it...
Cm7 is cyanogen mod 7 which is a "team" created rom that has a lot of added features that the stock Android does not have check out cyanogenmod.com for more details...
Miui is pronounced my U I and is another "team" created version of android that very much changes the look and feel of android...
As far as everything else... browse the development section and just read... that's the easiest and best way to learn
As far as battery life... there are a few roms that improve battery life... but there is no miracle solution. It's just a sacrifice that is made in liu of speed and performance... what I mean is... a dual core 1ghz processor uses battery... ya know
Also... if you need help try and post in the right section ... general or q&a ... don't ask questions in the development section .. for some reason a lot of people have a huge stick up their rear and rather than being helpful... they just get all rude and tell you that you are posting in the wrong section and are rude...

What are you saying? I truly don't understand what your trying to tell me. Would you please explain cfj521 ? Thank You cgarland
I think I can put flashing and cwm into simpler terms for you.
The word "flashing," in this case would mean downloading and installing a new ROM to your phone.
A ROM in this case, is simply a developer made android system that they make for the better and enjoyability of your phone.
CWM is an abbreviation for "Clock work mod recovery."
CWM was made for you to make adjustments to your phone, and install new software, ROMs much easier.
This system will be the head quarters of making adjustments to your phone.
-------------------------
Now, about getting NvFlash onto your device.
NvFlasher is, I believe, also a developer made program specific to our Nvidia Tegra devices. And also does make installing CWM much easier.
(Nvidia Tegra 2 is the processor for our G2x)
There is a section around here that explains to you how to use NvFlash for your G2x.
Which, I believe will be in the Android Development section in our G2x forums. Probably at the tippy top in a sticky forum (Highlighted forum).
The instructions may be a bit hard to following, but hang in there and just follow the instructions for NvFlash, refrain from stuff that isn't for now.
I hope I enlightened you a little bit on what we all talk about around here.
