Permanent Boot Loop - AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin

I own a Canadian S 4. I used TWRP to try and flash CM 13 and followed instructions as to how to do it. I also made a backup with TWRP. After trying many things to eliminate the boot loop, I am still left with the boot loop as I cannot get the recovery to load or anything else. Help!. I have tried all the suggested methods to try and cure the boot loop. I have also tried flashing the original ROM, and that will not work either. Lost as to what to do at this point.

Do you get any Odin error messages when flashing the stock ROM? Where did you get the stock ROM? You have an i337m?

I understand @audit13 questions... and I've used Oden... but may I suggest Samsung Kies emergency firmware recovery from a computer which i have also used but can't remember the differences between Kies and Oden..

Depending on the firmware on the phone Kies may not be supported. Smartswitch replaced Kies.

Can't install recovery on SM-T330NU

I tried installing almost all recoveries under T330 and T330NU but Odin keeps reporting as fail. I have tried Odin 3.09 and further without any hope. I even tried using another PC, installing drivers, and ,any versions of Odin but report fail. When I try to boot up the device it says Firmware upgrade encountered an issue. Please select recovery mode in Kies & try again. Kies and Kies 3 don't recognize my device. Oh and Stock ROM from sammobile and the one provided here in the general forum also report FAIL right after aboot. Am I hard bricked?

Russ, no you're not bricked, you have a flash that failed in odin, and if i understand it correctly you now have an instruction alive in your cache that executes at reboot resulting in kicking you back to that particular message/state in odin. Succeeding in a recovery or boot.img flash should break it out of that "loop". what changes have you made to your device that odin flashes are now failing? Also , are you using the factory provided cable?

I am using factory cable and have use other USB cables that are verified working. What I did was flash TWRP from sub77 and then tried to flash stock rom because it was being buggy. That is when the problem started and I cant go past the message. Although I can now access Download mode but when I try to boot up normally or to recovery I receive that message.

Okay download mode is good, flash the last known working recovery that you were using. Remember to DESELECT the auto restart option in odin.
when the flash is done [res-ok] etc. , force reboot to recovery and attempt a restore of your associated backup. Meaning if your existing backup was made with an older known working version of TWRP you must use that version. If Philz, then Philz.
Odin's later newer version is required to flash the LP 5.1.1 update for the sm-t330nu. see @thisisapoorusernamechoice 's thread for instruction.

safestrap....unable to mount /system...potential brick??

have rooted s5 on 4.4.4 nk2. Have been trying to install custom roms via safestrap. Apparently i am missing a step. I wipe data, try to install twi5ted Lollipop on custom rom slot....blank screen for over 30 min after reboot, phone gets real hot, take battery out. Try to install on stock rom slot, reboot then get stuck in boot loop and keeps booting into system recovery. I then saw through my hours of searching to format instead of wipe....so i format then try to install, get stuck again, take battery out, get back to safestrap dash now when i try to wipe/format/or even restore my backup it says unable to mount system. When i click reboot system it says no OS installed. After reboot, my custom slot gets erased.
I was about to try an odin flash back to stock but some how was able to get my phone back to a system restore. Why can i not get anything installed? Do i have to have odin to do a custom rom install?????? i know every rom is different but wtf. I have seen multiple videos and threads of people flashing zip via safestrap and rebooting into new rom without flashing kernals via odin or safestrap after rom install.
Also...my phone will not let me download zip files (ex. cm12.1) says unable to create download folder....how close to F'in my phone up am i? I have successfully rooted all phones in the past...s5 is giving me hell!
I just tried installing rom after format, then flash nk2 kernel from odin, still gives boot loop....ive tried everything i have found..never this much problem with custom rom..
When you try to install twisted it needs lollipop firmware which is flashed on odin, and based on your statement it says you're on NK2, a kitkat firmware. Try flashing a stock ncg tar and rerouting, downloading apps, etc. on the phone to see if that works. Also, I noticed you mentioned a cm 12.1 zip not downloading which, while unrelated to your current problem, will cause a bootloop when flashed due to the locked bootloader on the S5, so it isn't a smart idea to even attempt an install.

thanks, i will try fresh from start ncg. so you have to be on the current kernel that you are flashing a rom for, whether its CM, Twi5ted, Alliance...etc i need to be on rooted 5.0 kernel then flash rom via safestrap?
i was having problems downloading from internet on phone, not downloading rom if thats what you thought i meant. I just tried installing zip for CM 12 via safestrap and got same issue. Phone reboots, goes to black screen and eventually heats up like crazy. .... I just noticed, after my restore ...again... it says safestrap disabled in red on the boot screen, why is that? it says installed and tried reinstalling.
FIXED
So i flashed ncg from odin on the messed up phone and got messed up worse. Ended up getting stuck on first boot image of samsung android s5 boot screen. Finally found original stock firmare file and used odin to complete install stock os and got rid of root. Now back to normal... luckily i figured it out my self! thanks to the 100's who viewed and didnt help and thanks to mrjiggywiggy for giving me some input to help out!

S5 SM-G900F bootloop, nothing worked

Today my father's Galaxy S5 SM-G900F freeze after connecting to PC when I tried to copy some photos to PC. After that it started bootloop. Phone was ALL STOCK, no root, no twrp, no nothing without original latest android 6.01 directly from Samsung.
First thing I tried was wipe cache and factory reset. Nothing changed. Then I tried to download new firmware via Kies3, it took some time, update succesfull but still bootloop. Next I tried to put latest firmware G900FXXS1CPI6_G900FXEO1CPE2_XEO via Odin. Everything fine, succesfull but still no success, bootloop. Then I flash latest twrp on it. Twrp boot fine, I tried wipe, nothing changed. What can I do? Phone is bricked permamently or there is something I can do? TIA for any clue! I've read tons of forums and sites and everywhere told to flash firmware but it not worked for me
update: I also discovered strange thing when I tried to flash via twrp. After few second flashing (blue bar does not go forward) phone reboot itself and stuck on Samsung logo.

I think you must try a repair rom its come multi package boot loader and modem and ap and thetr is the pit file and be sure to get the proper one for your device and try to flash via odin
Thanks but it didn't work for me. I just tried 4 files (BL/AP/CP/CSC) and 5 files (+PIT). Everything success in Odin, recovery back to stock samsung but phone can't boot. Few times restart then stuck on samsung logo. Is any other way to try?

Might have Bricked S7 Edge SM-935FD. Need Help to recover

Hello guys
My phone is Galaxy S7 Edge Duos- SM935FD. I seem to have bricked the device.
Below are the actions I have performed.
1. Flashed TWRP using ODIN as described on https://www.the***********.com/root-samsung-galaxy-s7-edge/
2. Booted successfully into the OS. Found superuser app installed.
3. When I went to back to Flash ROM i erased multiple things such as internal storage/dalvik/cache/system after which device got stuck in bootloop. Showing NO OS.
4. I tried flasing Custom ROM Zip files through OTG. The process failed showing package corrupt and still stuck in bootloop.
I can enter recovery/download mode however cant seem to get the device booted. How can I get the device to work either Custom or stock ROM.
I will be going through some threads in the meantime, your guidance is very much appreciated.
Flash stock rom with Odin: This shouldnt be posted on Development Forum but rayher questions and Answers.
Find what your Stock Firmware for your phone is using Sammobile and flash stock then re do rooting and TWRP Process
zzThrain is right -- I wouldn't risk flashing custom ROMs at this stage, especially because many contain new bootloaders or other stuff that might make this even worse for you. Just pick up the relevant Samsung stock ROM file (from, for example, SamMobile) and see if it boots normally again. Once it does, re-do the process *after checking all MD5s of the files you used* -- I, too, have had it happen before that a download went corrupted and I flashed it. If all is well, get into Download Mode and let Odin rip.

Go to recovery mode & transfer rom to phone using pc. wipe cache, delvikcache, data only. No need to wipe internal sd. Install rom & reboot.
if you phone goes to recovery or download mode, no need to worry. If it doesn't go to neither recovery nor download mode, them your phone might have probably bricked.
It's my pleasure to help you if you still facing this problem

Hi
I tried flashing stock rom from sammobile. I could find for SM-935FD hence downloaded SM-935F.
It got stuck at 90% showing System in ODIN.
From the ZIP file which is the file that needs to be flashed among below ? I tried AP.
AP_G935FXXU2DRB6_CL12365438_QB16944063_REV00_user_low_ship_meta.tar
BL_G935FXXU2DRB6_CL12365438_QB16944063_REV00_user_low_ship.tar
CP_G935FXXU2DRAG_CL648265_QB8691891_SIGNED.tar
CSC_OJV_G935FOJV2DRAG_CL12785220_QB16560277_REV00_user_low_ship.tar
HOME_CSC_OJV_G935FOJV2DRAG_CL12785220_QB16560277_REV00_user_low_ship.tar
Now when I try again it immediately shows FAIL. Am i Flashing the right stock rom ?
It Worked. Thanks to all who helped.
I wasn't running ODIN as Admin and also was using an slightly older version V3.10.7.

I have an stock S8 that is boot looping. Do you think rooting or installing an different Rom is possible?

It's been a few years since I've done anything like this.
I can get into the recovery menus and wiped the device. It still won't boot normally or in safe mode.
Also if it's possible, what Rom would you recommend? I'm a Pixel user and really like it's UI.

I recommend to first flash a stock firmware to fix the bootloop.
You can check and download stock Samsung firmware files with Frija (https://forum.xda-developers.com/t/tool-frija-samsung-firmware-downloader-checker.3910594/) and then flash it with Odin.
Check latest stock firmware available for your device first then you can decide if you want to test a custom rom.
I flashed the official ROM but my phone hangs on Samsung logo screen. When I open stock recovery (as I don't have custom one), it says dm-verity verification failed and when I boot up my phone, it goes straight away to stock recovery and logs show recovery reason unknown no such file or directory. I have tried flashing multiple times but no luck. Odin flash is always successful.
