[HELP] Boot loop I9505 - Galaxy S 4 Q&A, Help & Troubleshooting

My I9505 is in a boot loop after rooting it today.
The problem occurred when I was trying to NAND backup through CWM. When the process got to "/system" a very generic error appeared, just letting me know there was an error.
After that I decided to reboot from recovery and it was stuck on the Samsung logo
I can still get into recovery but I don't have the stock ROM.
Any help is appreciated.

did you try wiping data and cache then reboot?

You can download stock firmwares from sammobile.com

I haven't tried that, I'll try that now.
A very strange issue has happened since the boot loop. It actually booted but the status bar was the only thing to show. no apps were avaliable and the background was just black.

EDIT: on reboot after wiping data and cache it asks for root, then when you select yes or no nothing happens
the splash screen now freezes

Flash back to Official Stock firmware by PC Odin.
By the way:
This is Development section.
Might try clearing cache or a factory reset otherwise, check here: http://forum.xda-developers.com/showpost.php?p=28481954&postcount=1

Thanks a bunch but I've downloaded and tried to flash these files and the problem is once the flash process reaches the completion of the install the device will auto reboot and again stop at the boot flash screen.
Even when I try to clear data and factory reset it immediately reboots and stuck again. I hope Samsung has a way to override everything and reinstall the stock firmware.

Boot Loop after formatting phone

Hi I wanted to completely clean my phone so i formatted it via open recovery, menu and then reloaded my stock firmware ready to flash custom rom.My problem is it flashes the rom ok but now is in a boot loop i.e. it boots up to the samsung logo and you hear the bootup sound then it reboots itself. I have removed battery re-formatted caches etc but it is behaving the same way, have I bricked it? is there something else i can try.
Thanks

[Q] My AT&T GS4 won't boot into recovery but will boot normally.

So I recently installed cynaogenmod 10.2 and now my phone won't boot into recovery. I was going to install gapps because I forgot to when I installed the rom. I do the correct sequence of buttons and then it shows recovery booting but then it vibrates and boots normally. I have no idea what's going on so any help would be appreciated.
Edit: Now it looks like it won't boot at all. I think I'll just let it sit for a bit.
Edit: Can I please have some help? I tried flashing a stock Odin firmware and now my phone won't boot past the AT&T logo.
Since using Odin, have you booted into stock recovery and done a factory and cache wipe?

+1. Factory reset will usually get you past a boot loop

Yeah I did that thanks, I hadn't thought that there was a "stock" recovery to do that with. I did it and now it works fine. I was still wondering why my phone wouldn't allow me to boot into recovery when I had 4.3 installed.

Did you perform a full wipe in TWRP before restoring your backup?

nope, i thought it did it by itself because it said wiping... when i hit the restore button
You may have to wipe system and format data before restoring.

Maybe reflash TWRP using Odin in download mode, wipe, and restore?

ok thank you so much for the quick help
Good luck. If that doesn't work, I suggest flashing a completely stock ROM from sammobile.com, factory reset, reflash TWRP, and then try a restore.

Nexus 6p bootloop (NOT same as Infamous BLOD)

Hi! Guys I have a problem, which doesn't resemble the BLOD, so here is what has happened. I was running stock android June build on 6p, rooted. And my phone started random reboots. I thought it could be fixed with either stock or custom rom. So I decided to flash AOSPA. I went into twrp but could not flash it, phone rebooted each time. I tried stock images via flash all command as well as manual. No rom worked although I could flash kernel etc. I used The Flash's custom twrp and fixed data and was able to flash rom easily, but it bootlooped on google logo, and rebooted. Now I can flash roms etc but it bootloops. Although Tesla rom did go into bootanimation before bootlooping.
So what can I do? Is it software related? What do you guys say!
PS. I did look into other threads, nothing was similar, although I did try a few mentioned fixes.

Use fastboot to FORMAT system, userdata and cache. Note any errors during the FORMAT process.... and then try flashing a full image from Google using flash-all.bat

I'd say you were squarely in a small group of people who are able to access and fully use Recovery but still boot loop after formatting and installing a clean image. If you've already tried a factory reset from the stock recovery I think you are done. Hardware issue. Replacing the motherboard is a fix, but not economically viable.
I had the same issue formatting data and cache to Ext4 and flashing modified stock ROM fixed. It would boot to Google logo freeze reboot and sometimes get to boot animation freeze and reboot.

Cortex ROM it's flashable stock firmware with extras . Though my symptoms where the same I hope I'm not giving you false hope. Worth a shot though.
The only was I recover my phone without replacing is using https://forum.xda-developers.com/nexus-6p/general/boot-images-bootloop-t3633723 < method from here... but the phone is lag af as it is only running 1 core on stock july build. Good luck for that.
I have the same issue going on. i was trying to flash magisx and suddenly it is stuck in bootloop. i tried flashing stock images and everything. i can access twrp and flash eveything and they are getting flashed fine but still it is stuck on the bootloop.

So have you used fastboot to FORMAT system, userdata and cache? Did each format command complete with no errors?
