Boot loop s7 G930F after twrp installation - Samsung Galaxy S7 Questions and Answers

Hi guys, not sure if I'm in the right thread (please move me if not admins)
I was running superman on my s7, I decided to clean out my phone by flashing stock firmware and then reflash a custom rom.
The stock flash went well as expected, checked oem unlock and USB debugging then I flashed twrp 3.1.1
My phone was then stuck on the 3 logo (I flashed h3g csc while stock flashing) for 15 minutes
So out of lack of patience, I rebooted my phone, now it's stuck on a boot loop splashing the Samsung boot image then resetting with a vibrate and this is constant.
I managed to open twrp on the phone and thought a wipe might be in order, did that and FAILED, without me rebooting it rebooted itself.
Then I tried to reflash stock firmware in Odin, again that failed.
Still stuck in a boot loop.
I know I've screwed up but any advice would be grand.
Thanks guys :good:

right, fixed the issue.
went into twrp, wiped the system by typing 'yes'
wipe dalvik, data and system.
rebooted into download via twrp and flashed stock rom again
works fine
all because i didn't uncheck auto reboot in odin when flashing twrp..... D'oh! :silly:
i iz idiot

I am somewhat confused with your writing, or you write the wrong information.
1. Wiped system in twrp as long as I know do not need to write "yes".
2. Twrp is not download mode, it is recovery mode
#Btw, this should not be in this section
Best regards,

Quick one for you, if you ever can't get to twrp after bootlooping. Press and hold power+home+vol up. Let phone reboot but keep holding buttons till it reboots a second time and then you will get download mode.

tHIS IS RIGHT SECTION FOR QUESTIONS AND DIALOGUES ABOUT s7, so proceed pls.

[Q] Phone stuck in reboot, unrooting doesn't work

Hey there guys.
I rooted my Blaze back in October, and loaded CWM 10. Things weren't working 100% right and I decided to unroot today to get the phone back to factory settings. Unfortunately, no matter how many times I follow the directions for unrooting the Blaze--using the .pit, and the updated firmware .tar--my phone still gets stuck in a reboot loop. It gets past the T-Mobile Blaze screen, but gets stuck on the SAMSUNG screen (it just has SAMSUNG flashing over and over, and then loops into the Android screen).
I've tried to flash the stock .tar about seven times now, and each time it's done the exact same thing. I haven't been able to find a thread to help me, despite searching enthusiastically, so I hope you guys can help me out. Basically, I've done everything the unrooting guides have told me to do, but my phone still appears to be soft-bricked. I can still get into download mode, Odin still recognizes the phone, and it always says that my process has succeeded, but then the phone still gets stuck in a reboot loop.
Any ideas?
Have you booted to the recovery and factory resetted and wiped cache?

I did before I tried to unroot it the first time, yes, with CWM. Now, the phone seems to think it's unrooted, so it won't let me go into recovery mode and factory reset.

Oops, sorry, I misinterpreted your question. Yes, when I boot into recovery mode I can factory reset, wipe cache, etc. I've done all those things before trying to flash the stock rom, and it hasn't helped.

So first register at www.sammobile.com, then search SGH-T769 under firmware and download the August 2012 ICS or The Feb 2013 ICS Firmware, wait for the download to finish (took me 30 minutes) then extract which ever firmware zip you downloaded then using Odin click on PDA and select the .md5 file which is located in the extracted ICS Firmware Folder that you've downloaded from sammobile.com
Download the PIT file here
http://forum.xda-developers.com/showthread.php?t=1919228
Click on PIT in Odin and then select the one downloaded from the link above
then make sure re-partition isn't checked and start the flashing process after it is done flashing and reboots you'll have stock ics
*BOOT LOOP MIGHT OCCUR*
To fix boot looping after flashing stock ICS just boot into stock or custom recovery and wipe data and cache then reboot and you're good to go.
Sent from my SGH-T769 using xda app-developers app

Thank u for the post my phone is alive again thank u alot i was trying to install twrp after i had cwm recovery and i wasnt able to install it so it soft bricked my phone but i used ur steps and it all worked out thanks :victory:

Rooted Galaxy s5 (sm-g900p [5.0]) Stuck on Yellow Sprint Screen - Im finally Stumped!

Phone Info:
Samsung Galaxy s5 (sm-g900p) (Sprint)
Android Version 5.0
Build: LRX21T.G900PVPU1BOA6
Hi, Thank you ahead of time to anyone who might have a minute to help me out. I have been combing XDA and as well as some other sites trying to find a solution myself but given my limited experience in this area Im at the point where I thought it best to stop and ask for help rather than do the wrong thing and have my phone blow up in my hands TNT style
I rooted my s5 a few weeks ago using Odin with C-f--auto-root, which went perfectly and I had zero issues afterwards.. This was only my second rooted device so of course I was exploring all of my new options out there to customize my phone.
The problem occurred after installing the apps Layers Manager and Layers Showcase (BitSyko Development) from the Playstore. Both seem like great apps and were not to blame for this problem, I just happened to be using them when I jacked something up.
Basically, over a day or two I tried several Layers Themes and they applied just fine, but one did not. Shortly after applying the Layer, and rebooting my phone I ended up on the bright Yellow Sprint Spark startup screen and my phone wont budge past this point.
I am able to boot into Recovery Mode as well as Download mode. I tried wiping the cache Partition as i had read to do as well as doing a full data clear and reset ,but it still; wouldnt move past the yellow screen. Then I very carefully followed directions to flash the stock firmware using Odin, making sure i used the right one for this phone and Odin displayed PASS! at the end. From what i could tell, it all went fine... But it STILL wont move past that enraging yellow screen!!
I think I may have missed something in regards to flashing stock firmware but i dont know. Ive read some other suggestions and things to try but, like i said, at this point and with my limited experience, I thought it best to concede and ask the experts for some help.
I hope I included any information needed...
Are you waiting long enough to allow for loading? Did you try installing a stock rom that matches bootloader version?

Hi, thank you for your reply. Yes, the stock rom i used matched the original rom on the device. I had taken some screen shots of the Device Info screen a while back for something else, so luckily i had a lot of general info right there shot the s5. And i waited a good amount of time. Odin took a few minutes and it read PASS at the end. From what i could tell, it was all done and i still waited just to be sure. But the more i think about it, the more i feel that i did do something wrong at this step. I'm just not certain what

Flash the TWRP recovery in odin
After that enter in recovery mode and format system, data, cache, dalvik cache, sdcards.
Then put the phone into download mode, and flash with odin the last stock rom (OG1) but make sure you don't have selected the "reboot" option in odin
After you got your phone flashed, take the battery out put it again and enter in recovery mode, choose "wipe data/factory reset"
Then put your phone in download mode and flash again the stock rom (OG1) this time with the "reboot" option selected
After you flashed your phone the first boot takes some minutes (in the yellow screen), just be patient.
After this you should have your phone complety clean and your problem solved.

see, nw this is the type of post i like to see!! @daniel3x , for future reference, idoneapps.com has WAAAAAAY faster downloads then sammobile and the tar.md5 files are 100% legit! But youre reply is pretty much exactly what i would have said. I personally would have advised on OK4 vs OG1. OK4 is just easier to mess with on TWRP and stuff.
wait a while for first stock boot from yellow screen
I've read that flashing a stock firmware will take 10 to 20 or more minutes on your first boot. Let the heat sink from your body and give it time.
I want to flash to a stock as well. Can I just full system wipe in twrp and Odin og1 or ok4>what I'm currently on and would like to keep it? Should I take out my SIM? Should I take out my sd card? Will I need to re partition my ext2/4 on the sd? Does the stock image replace the bootloader? I have a twrp backup on my extsd, can I use it after attempting to flash stock? Flash stock tar/zip should stock be a tar?, Odin kltespr twrp in pda mode, leave everything alone, root method of choice, phh su so flash in twrp, should I update Odin? I have 3.07 and 3.10.6. Then wait out that initial boot. I don't want a backup of what I have now because I've done things I wantedd to revert and do differently this time as I'm not AS clueless

Oh, some app permissions can cause a bootloop. Instead of flashing the whole stock rom, you can flash the recoveries through odin.
You can either:
-Flash stock recovery through Odin (BL slot) and perform a factory reset/cache wipe
-Go through TWRP and restore your backup
-Go through TWRP and wipe your cache partitions on ADVANCED WIPE

This salvaged my sprint phone
I had to flash back from LineageOS 14.1 to stock rom temporarily to "update profile" so I could make phone calls again after moving the phone to a new line. I tried several different versions of stock rom and flashed via ODIN, but all got stuck on the boot loop. It felt like I had searched endlessly for a solution until I came across this thread. I followed the process (Thank you @daniel3x & @youdoofus) using the stock rom ending in OK4; it worked flawlessly!
If possible, I would like to see this thread "stickied" for Sprint Galaxy S5. It will likely save other users a lot of time.

Need Help getting my phone working again!

Hi all,
I was running the new SaberMod Carbon ROM for a few days and decided I didn't like it so I tried to restore a nandroid back up of what I had been running before (rwilco's mostly stock). The phone wouldn't reboot after restoring the backup, it would start and then go right back to recovery. Then I tried just flashing the rwilco's mostly stock as new instead of from a back up, and that had the same results - said it was complete but when I selected reboot phone it just went back to recovery. So I decided to flash the stock tar in Odin, but that kept failing. Now I can't get into recovery, it says something about an update being interrupted. I can get into download mode, but the stock firmware keeps failing in Odin.
I am guessing here that my problem is that the SaberMod rom is based on 5.1.1 and the stock firmware for the G900P (as well as the other rom and backup I tried) are 5.0.0, and I remember hearing you can't go back to an older firmware version. Does this sound right? and if so how do I get my Galaxy working again?
TIA for all help and suggestions!

I have phillz recovery on it right now....can't get into the recovery though since it says a firmware update was interrupted. Would TWRP be better than phillz? and would flashing that get it past the firmware interrupted message?
I tried starting by flashing TWRP but that fails too....any other suggestions?
Can't flash anything in Odin, everything fails. Any other ideas before this thing goes for a swim in the sink?

Help, MMB29Q update wipes TWRP

Hi all,
Recently I updated my Nexus 5 from Lollipop to Marshmallow 6.0.1 (MMB29Q) - latest build.
everything stock works fine but, once I flash a customer recovery, in my case TWRP it stops working...I get either a startup loop or TWRP gets erased by stock recovery.
I tried various steps ...
flashed TWRP 2.8.7.1 - rebooted to boot loader was able to get into TWRP but, once I reboot system, everything works but TWRP is gone/erased and replaced by stock recovery?
Flash TWRP 2.8.7.1, then flash latest TWRP 3.0, reboot to boot loader and can get into TWRP but once i reboot into system, I am stuck on the initial boot loop.
I have to start from scratch of flashing system and boot etc to get past the loop and it still replaces TWRP with stock recovery.
I can always get into Fastboot but when I go to recovery it seems its being replaced by stock recovery.
anyone experiencing this issue? thanks for your help.
I guess I am doing something stupid but, not sure what...and thanks for your help
If you give more detail on the steps you are taking it will be easier for someone to help. Also, have you tried doing a factory reset when it bootloops?
thanks for the response..here are the details..
I had Lollipop with TWRP 2.8.7.1
yesterday, I downloaded latest build from android site...extracted all files....booted into bootloader and flashed all files..
rebooted - Marshmallow works perfectly...offcourse it not rooted yet or its locedback due to this flash
Scenario:1
So downloaded TWRP 2.8.7.1 and flashed it as recovery, no errors nothing...i rebooted to bootloader and went to recovery to confirm TWRP is there
I rebooted the system - TWRP gives option to root which I said yes so its rooted. I reboot system, this goes into bootloop - I wait for say 5-10 min in this loop mode and I see that adb can recognize the device but nothing else....its stuck in loop
when I force shut down by holding power button for few sec - and go back bootloader/recovery - TWRP is still there
***note*** I did factory wipe in TWRP but that did not fix above condition.
Scenario2:
exact same steps but after I flashed twrp2.8.7.1, I rebooted bootloader and flashed twrp 3.0 as well confirmed twrp 3.0 is flashed and rebooted system - phone start normally no issues - when I restart to bootloader - no TWRP exists, its replaced by stock recovery
Scenario 2, I tried couple of other ways and still the same thing happens - twrp 3.0 get erased.
not sure what I am doing wrong but TWRP doesn't stick
since this is my active device - i flash system.img and boot.img to get the phone to working condition
thanks for your help

Question Can't boot into anything whatsoever?

resolved​
I was trying to flash a gsi but when I boot into twrp it just goes back to the booting screen again when I press anything, I tried reformatting in wipe before it went back to booting but after that it's even worse. I went into odin and reflashed twrp but same thing. I flashed its firmware from samfx but one ui doesn't even want to boot, it just shows an endless charging logo. The only thing I can boot to currently is the default recovery and download mode. I really need help quick because I need to do some work on my phone.

When you install a GSI, the only partitions you should be messing with are /system and /data.
Did you mess with anything else?
Use Odin to perform a clean flash of the firmware, including a data wipe.

No I don't think I messed with anything else. Also flashing stock firmware again works somehow even though I already tried flashing it before, anyhow, I greatly appreciate your help
PS still not sure what caused twrp to bootloop
