SM-S550TL - Recovery, Testing, Misc - Samsung Galaxy On5 Guides, News, & Discussion

This thread is for whoever wishes to contribute to the development of this particular model, (Galaxy On5), Any and all help is appreciated!

As per request, I unpacked the stock recovery, repacked it, and attempted to flash it through odin. The result was "failed", on the odin side, but the device did not say anything, (This was in download mode).

Upload the boot image so I can compile it.

I would, but all I have is the recovery img. How I got that was from another user who got the firmware. I will ask him to see if he can send me the boot img.

OK I have not compiled TWRP with a recovery before so just to be safe I use a boot image. I just split it with Mkboot tools and replace the images in the device tree source code made for the T-Mobile/Metro version.

The build prop has to match in order for it to work. Upload the boot image and I can work on it.

Test image. Make sure to backup your recovery before you flash this. Use Odin and in the options tab uncheck auto reboot. Once flash is complete pull out the battery and put it back in. Holding volume up button and the home button and power until you get into recovery. Only people who knows what they are doing so we don't have bricks. I used the device tree source code made for T-Mobile/Metro and used the DT image and kernel from an extracted boot image.

It's pointless at the moment even compiling custom recovery for this device as it won't flash.
It seems this device has a locked bootloader.

Well it compiled with no problem with the Metro version all you do is enable development settings and select OEM unlock and USB debugging. I didn't have to use ADB for "fastboot OEM unlock". So I don't know. Thanks for the heads up.

Compiling isn't the issue, it's the fact the image is unsigned. There are no special headers I can see in the stock recovery image, which could cause the issue, so it seems purely down to the bootloader being locked down.
Also regarding OEM unlock and USB debugging.
It isn't and never has been required to enable usb debugging to flash a recovery.
I know this is incorrectly posted all over the Internet, but usb debugging is purely an OS dependent operation and has no use outside of a booted OS.
We are looking at alternative ways, but options are extremely limited.

I took the link down. Thanks.

Also check out the boot image. It's identical to the T-Mobile Metro version. Would you be able to test it out?

I dont own the device I'm just chipping in.
Where did you get the boot image, is it for the S550TL?

Yes it's for the S550L @hydroman202 gave it to me so I split it with Mkboot tools and compiled.

That was the recovery image I sent him wasn't it?

It said boot image so I split it and compiled it as on5ltetfntmo

Does anyone know how to perform "oem unlock" without fastboot? Every time I try to access it, it reboots back into the normal os.

Just the boot.img you found or the whole firmware?

also, i have been trying to find ways to unlock the bootloader of this device, but all of the methods i have found require root or fastboot. Do you have any ideas on how i might achieve root?

I wish i had the whole firmware, but it was just the boot img. I was pretty sure it was the right one, but i might have been mistaken.

[Q] Is my Maxx bricked?

Greets,
I think I may have bricked my Droid Maxx but I'm hoping someone can verify before I deem it a paperweight. I was on SU-2-3.3 and used Sunshine on it to unlock it and then TWRP to root it. After fully booting up the phone and verifying root, I rebooted into TWRP and ran a full back up w md5. After that, I booted up the phone and used supersu survival mode and then took the OTA update. Now the phone boots to fastboot, but says "boot failed" under any of the options. It won't go into recovery nor will it normally boot up. I tried to use RSD to reflash to the latest version but it just said flash failed at the first file and says something about downgraded security, etc. So now, I can get into fastboot mode and the phone connects and is detected but won't let me flash anything... it was unlocked via Sunshine, but I may have borked it up somehow. Thoughts?
Try a more recent firmware but check your recovery
Sent from my D6616 using Tapatalk
I took the OTA... is there something more recent? Also, I've tried to flash other recoveries but I get "boot failed" at the fastboot menu.
ohhhh you must mean try and use a more recent firmware via RSD. I'll give that a shot
Ok i tried a newer firmware via RSD, now the fastboot mode shows "failed to read signatures for partition aboot" RSD fails at flashing partition gpt.bin
Since I seem to have a partition related error, would this LINK help my situation at all?
Does anyone know of a way I can restore or rewrite the partitions via fastboot?

Okay, So if you think you device is completely bricked, and I mean "NOT RECOVERABLE AT ALL" , you can try this: This may be a long shot, you might want to try uploading 'sbl2.mbn' file. If you are able to flash that, then you can try flashing a "Broken" sbl2 file and try uploading the ROM using Qualcomm emergency downloader. This method is very dangerous, and not for the faint hearted. It is used to root the droids which cannot be rooted by sunshine (post SU4-21) and you may lose your rooting capabilities all together, as this method uploads a non rootable bootloader (SU6-7). If you can get your hands on a copy of the bootloader you already have ( SU-2-3.3) , you should use that to unbrick from the bootloader mode. Try to refer this post for further details.

If you can get into fastboot then I don't think you need to go that route just yet. You can try flashing the individual images via fastboot i.e. fastboot flash recovery recovery.img etc. It's been a while but I'd skip flashing the motoboot.img and gpt.bin and flash the boot.img, recovery.img and system.img.

Ok to clarify, after I unlocked via sunsine on 2-3.3, I rooted and I took the over the air so now I'm on the newer bootloader. Post those events I started to receive "failed to erase partition xxxx" I also just tried reflashing individual images from 4.4.4 su6-7 release and I still receive back "failed to erase... failed to flash... etc." I can get into fastboot mode but it seems crippled somehow.

This sounds like a promising method. If I attempt this method, will I be able to recover root since I was previously unlocked via sunshine prior to bricking/soft-bricking?

I don't think you can downgrade from SU6-7 to SU2-3.3. But I guess trying won't hurt. If you are able to flash a new sbl1.mbn and sbl2.mbn files, you might want to try rsd lite / mfastboot to flash the ROM image before you try the more dangerous path (CrashXXL's protocol, intentionally flash the broken bootloader and the using the qualcomm emergency mode to access the partitions) .
And answering your question:This WILL revoke your rooting capabilities and you will no longer have root. Though you can then use CrashXXL's method (same post linked above) to get root. But your bootloader will be locked, so no custom ROMs for you..
Good luck!

I think his bootloader is in a conflict as it might be looking for the certificates that are allowed, and sunshine is messing with the new installations. That is why I recommended a clean install of the device. But this is just guess work, I might be completely wrong!

Bummer. I'm not able to flash anything. All I get back is "Failed to erase partition." I did some extensive reading on the BLBroke/Qualcomm method and attempted that and still the bootloader replies back "failed to erase partition." I don't know what I should try next. Thoughts? Is the partitioning or memory bad on the phone?

Thanks for that. I posted there as well... from a software standpoint, I'm curious to know what would be denying access to the partitions...
I messaged jcase and he looked at logs for the sunshine preinstall and they were clean. It's possibly a hardware failure unless someone else with bootloader knowledge, knows how to get around the partition permissions access. thoughts?
I've tried a myriad of different methods... i just seems the partitions are locked down... "Access Denied" "Flash Failed" I have no idea what else to try. What do ya'll think? Brick city?

the prognosis is not good.
VBlack messaged me about shorting a pin to put the phone in Qualcomm Downloader mode... and then pushing software onto it to at least try to the partitions set up and get the bootloader in a manner which will allow for writing. If that doesn't work, there's nothing else to do. I read up on it extensively, and it's now a last ditch effort. I've never take apart a phone in that manner before, so it'll be a first for me.
Similar boat, here...using a programmer cord, I can flash a ROM onto the Maxx, but it stumble-boots into BP Tools mode after 3 or so failed 0-battery/unlocked bootloader warning screen loops. I can get it into bootloader with program cord, or first thing with factory cord. It won't charge at all, battery is new. Izzit hosed?

[Solution/Solved] Pixel Bootloop After Rooting Chainfire/Flashing boot-to-root.img

I stupidly tried to use Chainfires root method on my pixel by flashing boot-to-root.img. I am now stuck in a bootloop and I have no idea how to fix it. I can get into the fastboot page I think it is called by holding the volume down and power buttom. How can I fix this? Sorry if it is a dumb question. I tried using adb but don't know how it works and I get the error 'error: device '(null)' not found' when trying to do 'adb reboot bootloader'.
I really appreciate if anyone can help me. I am freaking out :laugh:

Try downloading the stock image and installing that from fastboot. If you are on a Verizon one and on 7.1.1 you are out of luck for root if you bootloader isn't unlocked.

Ok, stop freaking, this is very fixable. Assuming you have the Google version, or the Verizon version unlocked.
Short answer, we are going to get it into fastboot mode and we are going to flash you back to stock and probably save your data.
First, we need to make sure you have the correct version of Fastboot/ADB. It must be from GOOGLE.
https://developer.android.com/studio/releases/platform-tools.html
Unzip that onto a spot on your desktop.
Then go here and download the latest image for the Pixel. I am assuming you are in the US, get 7.1.1 (NOF26V, Feb 2017) for the Pixel.
https://developers.google.com/android/images#sailfish
Unzip that into a the Platform folder you made above with the fastboot tools. When you are all done it should look like the picture below. The highlighted items are the items that came from the Factory Image you extracted in step two. Everything else is from the platform tools.
Now RIGHT click 'flash-all.bat' and edit it. Near the end...look for the -w and take it out and save it. Removing that is what is going to save your data.
Power down your phone, restart it in bootloader mode. Power and Vol Down. Connect it to your computer and then double click 'flash-all.bat'.
That will take you back to stock unlocked and all your data and settings will be there.
Get past that and let us know. Then we will get you properly rooted. Yea, you used the wrong root process.
I love you <3
Thank you so much. I stupidly was trying to flash a file that wasn't an image file! I really appreciate your help man I don't know what I'd do if it wasn't for you.

No link handy, but here is how I do it. And yes, it is via fastboot, only way I know of at this point.
Download 2.7.9 SR3 SuperUser and copy it to your phone.
https://forum.xda-developers.com/apps/supersu/2014-09-02-supersu-v2-05-t2868133
Download TWRP RC1 and copy it to your fastboot folder.
https://forum.xda-developers.com/pixel-xl/development/twrp-alpha1-pixel-devices-t3500312
Using other versions than above will bootloop you. Reboot the phone into bootloader mode. Power and Vol down.
fastboot BOOT twrpFilename.img Where twrpfilename.img is the name of the TWRP file you just downloaded. Note is says boot in the command, not flash.
That will boot the phone into TWRP. Select Install and install the SU zip you copied to the phone above. And reboot the phone, done.
Thanks! That worked.

And be aware, when you unlock it...it will wipe all the data on your phone.
My pixel (stock, not rooted) is boot looping after the May OTA updates. Google support says to take it back to the store as it's still under warranty. Would the above fix work for my phone? Is it worth it, or should I just get a new one? This is already my second pixel as the first one died abruptly after 3 months.

Is the bootloader unlocked? If so I would certainly try flashing stock first. It can't hurt, and moments ago my Nexus 6 that I keep for backup was doing the same thing after the OTA. I just reflashed stock and it is fine now.

I think so, but am not 100% sure. Was bought unlocked from a retail shop. (Sorry, am a bit of a newb!)
So please let me understand
I am on 7.1.2 april (N2G47E), and if I want to update to may N2G47O the steps are:
- sideload ota
- flash new bootloader from may factory image
- twrp RC1 and supersu 2.79 sr3
Does this work or do I have to make something different?

Sumsung j7 duo sm-j720F recovery and root ??

Hi all
I can't find the recovery and how to root my Sumsung j7 duo sm-j720F with oreo android
Any help plz
And thanx in advance .
No one answer seems like no root and twrp at thise time
Unfortunately the reason you can't find it is the same reason, why nobody can find it: it simply does not exist...
Try Magisk. (I've personally tried and succeeded).
1. Extract "boot.img" from J720F's latest stock firmware and copy it to your sd-card.
2. Install latest Magisk Manager apk.
3. Through Magisk patch the stock "boot.img" in Odin flashable ".img.tar" format.
4. Copy the "patched-boot.img.tar" to your pc and load it in Odin's "AP".
5. Make sure your phone is OEM unlocked.
6. Go to recovery mode and make factory reset/wipe data for best result (I've not tested whether it works without factory reset)
7. Go to download mode (Newer models like J720F doesn't support previous download mode access method by pressing and holding volume down+home+power buttons. New method is pressing and holding "volume down+home" button and attaching the usb cable).
8. Flash the "patched-boot.img.tar"
9. After restart finish additional setups in Magisk app.
10. Enjoy!

Thank i ll try
The only thing that i not found is OEM unlocked i have not thise option in my j720f ?
You will find OEM unlock option under "Developer Options" menu. You need to enable the menu first by continuously tapping your "Build Number" for 7 times in a row. Remember that enabling OEM unlock will automatically factory reset your phone. So don't forget to take a backup first.
I suggest you to first install magisk, find the stock boot image and patch it through your phone, then copy it to your pc. Backup everything else you need. Then enable OEM unlock. This way you need to reset your phone only once.
Sir i m try alot to patch boot.img but installing failed error. Can u provide patched boot.img.tar file i really need it
Thank yo

Strange indeed! You should have the option! In my case it's between "Bluetooth HCI snoop log" and "Running services".
What's your firmware version? Is it the latest one? My build number is "R16NW.J720FDDU3ARI4".

I will try to provide it and will post the link.
But why can't you patch? Is there any problem with Magisk? Or you cannot install the patch through Odin?

However for your convenience I am providing the patched boot image.

This is extracted from the latest stock firmware having build number J720FDDU3ARI4 so please confirm yourself that you are using the same firmware.
Download and flash it through Odin and let me know about what happens.

Sorry to hear that. Did you tried a factory reset? And still there is no OEM unlock? If yes then wait till the next firmware release. Or continue searching for any other method. If I come across something then will definitely post here.

Thank you for the img files. Unfortunately i have a problem. When i try to boot the October image with fastboot on A slot where my phone is updated to the october patch - it stucks on android logo. When i switch to B slot which is September patched and use the september img u provided - again the same thing. Any idea?

Thats weird... what model do you have? , I thought they work on all Models...
On my device (TA-1012)[Single sim 128gb/6gb], I have exactly the same patches on a and b and both work like a charm with their specific images... Just redownloaded and tested it again...
To narrow down your problem further:
Did you flash anything else? Is your device booting normally when just rebooting? Root? Twrp?

If you have another model and some time leftover I would greatly appreciate if you(and everyone else reading this with Another model):
1. could reflash the 4.88 Stock Image
2. Turn off automatic update
3.follow this Upgrade guide over and over again
https://forum.xda-developers.com/no...root-nokia-8-ability-to-t3848390/post77751877
4. Afterwards send me the stock_boot_(randomstuff).gz Magisk generates as Backups in the folder /data or (only viewable with root explorer) AND a screensho of the file creation dates so I know which is which...
I would then upload them and add them to the thread to help others with your model...
No worry's if you don't have time...

Thanks for the replay! My device is TA-1012 [4/64]. I haven't flashed anything. I neither have TWRP or root. When rebooting it is showing the warning that my bootloader is unlocked (offical method). But i noticed something strange. Maybe you will laugh at me :laugh: but the thing is when i boot the phone and the warning pops up it says to press the power button to continue but that doesn't work. I have to wait to boot itself. In the other hand when i boot the stock images you provided the power button works and when i press it, the warning disappears and the android logo pops up. I dont know if this was helpful in some way but i wanted to mention it. Also i will post the backed up img soon that you wanted up there.
Ok so i came up with another idea. I forgot to mention that all these steps i did on Linux so i have Windows also and switched to see if the things are the same. When i enter in cmd, adb recognizes the device without problem. When i write adb reboot bootloader everything is fine. BUT when i write fastboot devices when my phone is in download mode , nothing happens. When i try something like fastboot reboot or fastboot boot xyz.img it says <Waiting for device>. I tried adb and fastboot installer but again nothing. I cannot find nokia drivers, but in OST LA there are 3, i installed them and again nothing. So what should i do?
Edit: It worked when i downloaded new version of adb and fastboot CLI but again - booting the oct img even in Windows cmd makes the phone stuck on android logo

The Power Button stuff is exactly the same for me... Don't think thats the issue...
Really weird, would love to debug further but really have not much other ideas...
Did you try newest fastboot/adb binaries on windows too?
Do you have access to another pc to try it on?
Switched out cables/ports used?

I've switched ports, tried another pc even with different OS (win7). Downloaded the newest adb and fastboot binaries from Android Developers site - nothing. Also i ran a test in fastboot and its says:
bootloader unlocked: true
critical unlocked: false. But i dont think critical is necessary, isnt it?

I think i should try to flash the stock firmware provided in the forum i think it was the June one. Maybe that will make my device able to flash your images
I have similar issues. I have ta-1012 4/64. When it was of september patch, no september image worked (modified or not), it stucks at "android powered" logo. This is the volatile booting which is performed by "fastboot boot" command.
I use a linux desktop. I tried the latest fastboot executable which came with android-studio and also the one on archlinux android-tools package. (they are a bit different) Results are same.
Now it has october patch. No success with october boot images, too

A205u bootloader unlock, twrp and root

*****I am not responsible for anything you do to your device. Do this at own risk***** If all goes bad just flash Factory firmware with PIT file.
Credit goes to those who built twrp.img and the vbmeta image for the A30/A70. I am no dev, I read somewhere about the crossflash to DS firmware but cannot find it any more.
This is for people who understand Odin and have some experience flashing firmware.
Maybe someone will make noob friendly instructions, please feel free.
I currently have an a205u with an unlocked bootloader root and twrp.
1. Using Patched odin crossflash to DS firmware. OEM toggle-download mode-unlock bootloader.
2. You are now able to flash back to the W/U firmware keeping an unlocked Bootloader even though you will not see an oem toggle in developer options
3. Patch boot with magisk 8.02 compress it to tar file along with A30 vbmeta.
***** Important***** make sure to use 7zZ for all steps, and rename boot from magisk_patched_image to boot.img or you will receive errors.
( I may have used a70 vbmeta as I was trying various ideas someone will have to try this and let us know) It will hang at samsung logo for a while on first boot.
4. Then flash A30 TWRP using flashify. Probably works with odin too. Boot to recovery- Perform format data, reboot recovery, flash dmverity+magisk. May be able to get it to work in less steps that's just what I did to make it work.
Link containing vbmeta , magisk patched boot Patched odin . Bootloader 4
First time flashing I got a pass in Odin and fail on phone Flash the second time everything was good

So far it seems DS refers to the singapore version of a couple Samsung phones.
The a205FN would be the closest version in that regard and it's got a recent version of Android.
