[Q] need help using cwm

Thanks in advance to anyone who can help me. So I'm new to rooting and new to xda, I looked around the forums a bit but am unable to find exactly what I'm looking for. I have a Sprint note 3 smn900p. I successfully rooted it using towelroot and confirmed with root checker. I then downloaded Rom manager and used it to download cwm. Here is where I need help, I boot up my phone and this is what I get. (Volume down, home button, and power)
Odin mode
Smn900p
Samsung official
0x0
0x1 (towelroot did not trip this, it was either RM or CWM)
Qualcom secure boot enable (csb)
Rp swrev s1 t1 a1 a3 p1
Write protection enable
Udc start
At the bottom it says "downloading" and "do not turn off target"
That's where it stays and the only way to get rid of it is to do a battery pull.
Now if I hold volume up, home button, and power this is what it says.
Recovery booting
recovery is not seandroid enforcing
Set warranty bit enforcing.
Phone then starts up normally.
I am trying to do all of this without a computer because I don't always have access but any help at all is appreciated. The main reason I am rooting is to get free wifi tethering for my note 10.1 and after that possibly getting rid of the bloatware and overclocking the cpu.
Again thanks to all the developers and anyone else who makes this possible. You guys (and girls) rock!

You use Volume DOWN+Home+power button to flash firmware by USB using Odin program or restore original firmware using Samsung Kies.
The only way you can exit the Odin mode is remove the battery or after having successfully flash a firmware.
You use Volume UP+Home+power button to enter recovery mode. In recovery, you may be able to perform:
- backup of the entire OS and data of the phone.
- recover from a backup in case you encounter any problem flashing a custom rom, etc.
- perform a full wipe or factory reset
- install custom rom or firmware file saved on phone memory or external SD card.
You may use ROM toolbox to remove unwanted bloatware and overclock or underclock your device.
Please hit thanks if I helped.

But isn't it possible to flash roms/kernels using just your phone? Also when I do hit volume down home and power shouldn't I at least have options from my phone on what to do next, and shouldn't it say something about using cwm? Btw Thanks for the quick reply!

Did you install CWM?

It's not clear from your post whether your really installed CWM recovery. Use Odin (download mode) to flash tar.gz version of CWM (or TWRP). Search for the links yourself. Then you can enter CWM with vol up+home+power combo.
There on, you can flash any (other) recovery or ROM from phone itself via CWM (or TWRP or Philz).

Yeah, it is possible to flash ROM using your phone memory or external SD card thru Recovery mode (Vol UP+Home+Power).
I suggest you use [root] Mobile Odin Pro (this can be downloaded on play store) if you want to flash kernel/ROM without going to recovery mode. It is also safer to use than flashing in download mode.
For a more user friendly recovery, try using Team Win Recovery Project (TWRP).
It is touch-based recovery. Easier to use.
Please hit thanks if I helped.

Ok so I'm going to download twrp, if I did in fact download cwm will these interfere with each other. Also once I download twrp do I have to open it on my phone or just flash it through recovery mode or through mobile Odin pro. (Sorry for the basic, probably stupid questions)

I flash mine using mobile odin. It will replace CWM.
Download the TAR file save it on your external SD.
Open odin.
Grant superuser request
Open file...
Select TAR file
Flash firmware
Your phone will reboot in recovery.

Ok so I bought Mobile odin pro from the play store now if I want to flash a Kernel to my device I would need to find it on here and then download it correct or I could find a rom with the kernel already on it and flash the whole thing and would I be able to find it on mobile odin or rom toolbox? Thanks again you guys are so helpful taking it baby steps with me.

What I meant on my previous post was I flash my recovery which is TWRP using mobile odin.
I suggest you flash TWRP recovery first using odin. Perform backup in TWRP before flashing any ROM in case anything goes wrong, you may be able to go back to the original state of your device.

defiantly follow the previous reply and backup first (very important).
i personally dont download roms etc from apps. i prefer to find it manually on the forum, so you know you have the correct, most up to date file for your device. also, you can read other users post to get an idea of how its working and the possible problems with it.

Ok sorry I took soo long to respond, work has been busy. So I Bought Wifi Tether Router for $2.50 which is still better than 10 extra dollars a month. It works, granted it takes a long time to start up and im not using the stock tether that is included with the phone which would have been great but it gets the job done and I have no complaints. This was one of the main reasons I wanted to root my phone. Anyway I guess when I have some more time to mess with it I will try flashing roms/kernels (I am just soo afraid of hard bricking my phone) but you guys gave some pretty clear instructions so I don't think I'll have a problem. As soon as I get a chance to do some messing around I will let you guys know how it went. Thanks again hopefully one day I will be able to return the favor.
Ok just double checked and now I need to ask another question. Mobile Odin states that my reactivation lock needs to be turned off but when I go to settings, general, security, there is no option to turn it off. It doesn't even show it in the list. Do I absolutely need to turn it off, would it be somewhere else?

i don't know. i looked into it and it appears it should be under security, but that was on a s5. maybe your device doesn't have that option.

Do you know what would happen if I backup or flash a rom and the reactivation lock is enabled?

i dont know exactly, but through some research it looks like you could run into issues with a custom recovery. i can only assume a rom would be the same.

That really sucks, I'm gonna try and hopefully find a way around it but until then I guess I'm gonna have to wait. Would you happen to know how to check and see if it's activated? (Besides the normal spot in security that it should be)

sorry, i don't know. i had to google search to find the previous information.

What device do you use? Have you enabled this feature (reactivation lock) before? I've made a research that this is an anti-theft feature of galaxy s5 and note 3 which prevents fatory reset of the phone using your samsung acccount when stolen.
I think you don't need to worry about disabling this feature if you never enabled it. I'm using galaxy s3 international version (i9300). And I also don't have this feature. Mobile odin is only reminding you that you should disable reactivation lock (in case you have one) before flashing any rom.
I "guess" reactivation lock enabled will prevent you to format certain partition in your phone since it will be password protected.
I suggest that you use TWRP or CWM when flashing ROMs that are not touchwiz based (Cyanogenmod, AOKP, etc). I only use Mobile odin when flashing recovery and flashing stock firmware. Flashing custom ROMs other than stock, in my opinion, will be safer if you do it in recovery after a backup.
I hope I answered your question.

You could try the steps for N915T or the note 4 like suggested, but otherwise idk. I personally haven't tried them yet, so I can't vouch for either.

Unable to root my Edge
I am a little baffled.... I have been rooting my phones for more than 10 years, and usually the auto-root files work fine. However this time it seems, that my phone seems to be smarter then I am.
I have been trying to root, my Sprint Samsung Galaxy Edge for more than a month. I started by downloading the correct file from ChainFire, however after my first attempt to root the phone was unsuccessful, and I was left at a screen saying a "firmware update had failed." Leaving the phone dead. I was fortunately able to pull down a a copy of the NK1 firmware and restore my phone to a usable state, but i have not been able to find a solution to rooting the phone.
I have seen one thread that suggested using the SM-N915T file, but that failed as well, requiring me to re-apply the original firmware. So I was looking for any suggestions that someone might have.

follow instructions to the period. I have rooted all of my Edges without issue.

So I just wanted to confirm the process. I am already at NK1 so I assume I would start at step 2, but the file that downloads does not appear to be a typical tar file that one would upload via ODIN and download mode. What steps do I take to flash it? Is this one that I need to copy to the sd card and then apply by going into recovery mode, and use the apply update from SD card option?

Grumbles
So..
I tried going ahead and placing the zip file on my sd-card, and applying the update via recovery mode, and selecting "apply update via the External storage. " Not only did that fail to result in obtaining root access, but now if I go back into recovery mode, I get a message that updates via ADB and external storage are disabled. I can reapply the original firmware and restore access, but that still leaves me at square 1

I have successfully rooted my sprint N915P from a member on here. Followed directions to the T. Now i can't find the original poster to thank him. He's a god.

Tried to root, failed, total noon here.

Hey guys, today I tried to root my t-mobile s7 from a random YouTube video I found. After flashing a file from Odin, my phone got stuck in a boot loop.
I did a factory reset from recovery and the phone started up fine.
Now here's my problem, after doing a reset, the first thing I noticed was that while I was booting up the phone. It showed the usual Samsung Galaxy S7, followed by an unlocked padlock with the words "Custom" under it.
2nd issue. My phone just looks a lot different than when I originally bought it. It is also very sluggish, experiencing a lot of lag.
I've looked up how to go back to stock firmware but I'm not sure which one to use.
Any help would be appreciated.
I'm currently on the PG1 firmware.

It appears you still have the eng kernal... You can just re-run the root.bat and install SuperSu, or if you want complete stock follow the steps below:
*Also Before you try this turn it off and let it charge for 45 min-1 hour or so...*
1. Volume Down + Power + Home to put it in download mode
2. Then press Volume Up to continue past the warning screen even if nothing is displayed.
3. Grab The Latest Version of Odin here
4. Then Download The Stock Firmware, in this case you will need whichever version you have (if you do not remember you can just download the latest available firmware) Download Firmware and then extract it. (If you have 5 different files in the zip go to step 8)
5. Then install Samsung device drivers(if not already).
6. Start Odin, Plug in the S7, Load in the tar.md5 in the AP/PDA and uncheck Auto Reboot and Repartition.
7. Let the phone restart... VIOLA!!!
8. Alternatively if the zip has 5 files... They should all start with the corresponding buttons in Odin For Example:
AP_G930TUVS3APD8_CL7856276_QB9546176_REV02_user_low_ship_MULTI_CERT.tar.md5
BL_G930TUVS3APD8_CL7856276_QB9546176_REV02_user_low_ship_MULTI_CERT.tar.md5

HOME_CSC_TMB_G930TTMB3APD8_CL7856276_QB9546176_REV02_user_low_ship_MULTI_CERT.tar.md5
After they are entered into Odin you hit start and after a few minutes ... It should be fixed....
Let me know if you have any further questions or issues...

The custom is normal since you flashed a modified kernel.
Follow this instructions here for rooting / unrooting.
Most of these applies to Tmobile S7, expect specific ones mentioned for Verizon.
http://forum.xda-developers.com/ver...-to-notes-root-install-xposed-unroot-t3411039

Thanks man, I'm gonna try to finish rooting. I thought my phone was just screwing up and the first part of the rooting process failed, since the bootloader.
I also tried sammobile and the download won't start.
If I were to download an earlier firmware, would I be able to update it to the most recent one?

Is it possible to revert to stock without wiping data?

Can I flash a custom kernel with flashfire?

No you cannot. Or rather, science threw bootloader is still locked, your phone will not boot if you try.

Quick question, I bought a used s7 edge off Craigslist and when it's asking me to log in with another guys email. I tried contacting the guy I bought it from but he hasn't texted me back yet. Can I root it and install another rom on it to bypass the lollipop lock? Thanks guys.

Wait did you try rooting the s7 or s7 edge... (Or is the s7 edge completely unrelated to the brick)

Trying to unroot a Galaxy S6...losing the will to live :(

Can anyone help? I spent a big chunk of my hard earned money on a refurbed S6 for my daughter, she's had it about a week (she's Pokemon mad btw). The latest update for Pokemon Go came out and now she's blocked from the game as it appears the phone has been rooted. If I'd known, I wouldn't have bought it. Anyway, for the last 2 days my partner and I have been trying to unroot it. We've used various versions of Odin to no avail. I had a lot of trouble finding the right firmware because it looks like the phone was Polish according to the version and CSC numbers, and tbh I'm still not sure if we're trying the right one. Software is 5.1.1. right now. I've tried installing SuperSU but it won't run, it just crashes the phone and forces a reboot. We've tried manually unrooting with a file manager but the su files we need to delete reappear seconds after they're deleted. I'm at the end of my tether, does anyone have any ideas?

You won't be able to unroot it until you flash stock firmware. I don't know if the game checks the knox status.
Give this a go

Unforunately my partner spent almost all night trying to flash the firmware. According to him it 'nearly' worked, however, I now have a phone stuck in a boot loop. :crying:

Smart switch won't work, says it doesn't recognise the device

I think I would give original firmware of your country and odin a try. One of possible ways is to download all needed files from the site of sammobile.
For me this way works every time when I stuck in boot loop. Odin functionates when you are in download mode. Switch off your s6, then start by pressing home-, powerbutton and Volume down at the same time.
Then start Odin on PC, then connect USB and so on.

When you select emergency recovery theres an option where you have to write the device model and the serial number

Use kies 3 on your computer. When you get it do a "firmware upgrade and installation" it will ask for your serial number which you can get from download mode when pressing the home key. After that kies 3 will ask to boot your phone to recovery but instead boot to download and bow your phone will flash to stock. This method always work!!

Thanks for the reply. Unfortunately I've tried Kies already and I can't get it to work at all. I get a message telling me my device is not compatible and the whole thing just stops. I'll give it another go though, no harm in trying. Thanks

@amber_1978, Pokemon Go does not check for root. The only thing it does seem to check for is location spoofing via another app. I'm using it on a rooted, Knox tripped, Xposed installed phone with no issues.
If you want to return the phone back to stock, the best way IMO would be to use Odin to flash a stock image, such as the EPD1 firmware.

Really? Did you do the latest update in the game and it still worked ok? This phone has definitley not been used for location spoofing by us and I'm pretty sure there were no apps of that nature on the phone. I downloaded a root checker when everything went wrong the other day, it said the phone was rooted. I'm totally at a loss tbh. Right now it's still in a boot loop. Trying to flash it with Odin as we speak.

Just an update. Tried Smart Switch. Tried the model and serial numbers on the back of the phone case, these weren't recognised so I went to the recovery screen and hit the home button and got a completely different set of numbers. Different IMEI, model number, you name it. I'm assuming this is why Odin won't work, I'm looking for the wrong firmware? I obviously have Frankenstein's phone. No idea what to do now.

Best thing to do is to flash TWRPP and try to flash a custom stock rom through the TWRP recovery which does not have root installed..... If that doesn't work try to find a generic stock firmware for Odin, meaning a firmware that can run in any country..... If all else fails update it to 6.0.1 stock firmware. Try the closest firmwares to your location.
And if you do manage to get to the Samsung logo let the phone sit there for a good 10 minutes even if it reboots....
When I bricked my Samsung I used masiks custom 6.0.1 rom based on stock, but had all the links to bootloaders cscs radios and what not so giv that a shot if you can find it.

do you have lucky patcher playstore installed ?

SM-G955U1. XAA version. Bootloop problem, any help?

MY BAD, PLEASE MOVE THIS TO THE CORRECT SECTION. I'M REALLY SORRY.
Hello!, my mother bought this phone for her in the US and from day 0 it has been having problems. She couldn't use wifi or bluetooth for example, and sometimes it just kept restarting till it worked again, but without any connectivity functions, except mobile data.
I tried to fix this updating the phone using Samsung Smart Switch to the last build (AQL1) but now the phone is stuck on the boot screen no matter what I do.
Tried flashing with Odin, it worked, but the phone is still on boot loop. I read somewhere in this forum that you can install an older version of the bootloader to take the phone out of this hell and I did it, using the build AQK2 bootloader but no luck, same problem.
Also, the phone doesn't have USB debugging enable nor OEM unlock either. I can access both recovery and download mode though.
At this point I'm out of ideas, can someone help me with this one?
Thanks in advanced.

Thanks for answering. Where I live there is not a single Samsung Service, only at like 1800km from here, that's why I'm trying to solve this by myself but seems that this is a hard one... I hope someone can help me to deal with this as it was a big investment :/
Thanks again!, if someone knows a way to help please tell me.

No I haven't, I will give a try soon through web chat.
I mean, this shouldn't be happening, it's a brand new phone, all over the internet are people with the same problems as me and looks like so far there is no solution.
Maybe it's a faulty phone/hardware? My knowledge is not enough in this matter.
See you!,
Federico.

I need a couple things from you
1. What model does it say on the back of the phone i understand you posted it in the header but please for safety sake .
2. Go into download mode for me so i can see what carrier it lists
3. Try wiping data cache in recovery

Thanks for answering!, here it goes:
1. It says SM-G955U1
2. Carrier: XAA
3. Done, still the same.
An update from my last post:
After a few bootloops the FRP screen showed up, as the phone can't use wifi yet I managed to access using mobile data and enabled the USB debugging, but after trying to enable wifi the phone froze and went on bootloop again, so still the same but with the USB debugging enabled. I'm currently on the build AQK2.
Thanks again, and I hope we can fix this.
Update 2:
I cleared the cache, after a few bootloops the phone actually boots (gets to the lock screen), and it restarts again while the message "Android is starting" is loading, so now it's a different type of bootloop I guess. It does the same even in safe mode.
I will turn it off for now.

Sadly it didn't work. The phone is still loading till "android is starting" sign and then restarting again.
I will write you so you can help me through pm, could this be a faulty hardware?

I'd like to know the other solution too.

I will tell you all what todo as a last resort.
IF YOU CHOOSE TO DO THIS I TAKE NO RESPONSIBILITY IF YOUR DEVICE STOPS WORKING OR DOES NOT TURN ON!!!
Follow all previously said steps i outlined but when you go into the options tab select nand erase all also then flash device.

@fefin -Sorry to hear that you're having issues - But I'd like to clear one thing up - Your comment that this is an issue "all over the internet" sim isn't true... I don't know how many Millions of S8 / S8+ have been sold - But your post is the first that I've ever heard of anything like this... I concur with the recommendation that you call or Chat with Samsung Technical Support - Preferably before you find the phone completely unable to Boot into Download Mode - Get Samsung to help you - or you may risk voiding the warranty if Samsung determines that you are ultimately responsible for the state of the phone ??

Thanks for answering!, sorry for my late response.
Well, if you check samsung's official forum there are a few threads with 15+ pages of people complaining about wifi issues (https://us.community.samsung.com/t5/forums/v3_1/forumtopicpage/board-id/GS8QA/thread-id/862/page/1 and https://us.community.samsung.com/t5/forums/v3_1/forumtopicpage/board-id/GS8QA/thread-id/30601/page/1) about bootloop problems, (https://us.community.samsung.com/t5...id/GS8QA/thread-id/3920/highlight/true/page/1) also there is a post on another webpage talking about bootloops on this model and how to fix them (https://thedroidguy.com/2017/12/sol...p-issue-s8-turns-screen-remains-black-1079013).
I know it's not representative, as you said, millions of phones has been sold, but what I meant when I said "all over the internet" is that you can easily find people with this same problem. This shouldn't be happening, not on any phone even less on such an expensive phone.
I think the phone is officially dead, I took it to a well known local technician and even him couldn't fix it. My nearest official samsung service is 1600km away. On the other hand, my aunty got for herself an S8 and it's working perfect, so it's just bad luck for my mom I guess.
The phone had issues since she bought it (wifi and bluetooth didn't worked at all, but she is not really a tech person so she thought it was fine), the phone was working with some bootloops from time to time and after a while it fell from and got a little crack on the top but it didn't change the behavior of the phone, it was still ****ed up. That's the thing, because of the crack I'm pretty sure they won't take it back or even try to fix it (for free at least), they will say the problem is because of the fall. I'd been reading a lot about this and seems that I'm pretty screwed D:
I will sell the phone for parts. At least I will recover 60% of the initial investment.

If you have some 'proof' the problem existed, before the crack, and can prove when the crack occurred, or reasonable determinate approximation, small claims court will vindicate you, and Samsung will have to pay.
Sad to say would take a little time of yours to get them there, but it is an easy process, and with reasonable ability to determine/evidence those two things, a sure win.
But still a PITA.
