Samsung S6 stuck in boot loop - Galaxy S6 Q&A, Help & Troubleshooting

Hello,
I am new to rooting so I hope what i say makes sense.
I recently rooted my Samsung galaxy s6 G920IDVU3EPC6 yesterday. After seeing a update notification pop up it took me to twrp where I tried everything to get out of it, install the .zip thing. reboot. Nothing would get me out of the twrp menu. stupidly, I did an advanced wipe and it appears I got rid of all the system files or something like that.
Now the only thing I can do is enter the blue download menu or get stuck on the boot logo screen forever. I have made backups of my files on my PC. How do I get my phone back? please help me!

Hi,
Samsung OTAs (Over The Air) updates won't work on a rooted device. It has rebooted into TWRP, because normally it reboots into it's original Samsung recovery and installs the update. But because TWRP replaces the Samsung recovery, it doesn't work.
And if you have wiped the System partition, you no longer have anything installed. No Android, nothing.
The easiest thing to do would be to flash the original firmware for your device. Then you can do the update, then root your device.
A good habit to get into when you have TWRP installed is to do regular TWRP full backups. That way, if anything happens (like wiping your device), you can just restore that backup from TWRP, and the phone will be exactly as it was, with all partitions intact

Nexus One doesn't load past the multicoloured logo

Ok I have a massive problem here. Last night I decided to use the 1 click universal root app to root my phone and flash it to get CM.
I downloaded the app did the root, downloaded clockworkmod then did a clockworkmod recovery. After that finished i was given a pre-root option to backup my phone and wipe data/storage.
I only chose back up my phone. My nexus one then rebooted and proceeded to backup my phone then it went to install CM 6 RC2.. After this had finished it then rebooted and went to the multicoloured animation where the colours ceom from the left and right..
Here it would continuously loop and never do anythign else. With this I pulled the battery and loaded into recovery where I was in ClockworkMod. I then proceeded to use the recovery and as it was doing the recovery it just froze and the progress bar nor any words would come up.
From here I pulled the battery again did a soft/hard reset but it would hang on the loading animation again. I then did a wipe data/clean option and now it just hangs on the X logo.
On my sdcard I still have the clockworkmod folder with the backup, nandroid, system and all the other files as well. Vodafone Australia have no stock of the Nexus One at all and won't be getting anymore in since it's a finished product
I barely have any cash for a new phone and need to know asap what to do to fix this problem! If anyone can help!
When you installed Cyanogen CM6 did you install the proper baseband also or you just didn't write it down for us? If you had 2.2 on the phone before you rooted the baseband is ok for CM6.
Did you try hooking your phone with USB and try if ADB interface works? If your computer sees the phone via fastboot?
IF fastboot works, you could always restore your stock recovery and install a stock FRF91. (And then try again with CM6, this time installing the proper baseband AND WIPING like you should when installing CM6!!)
When installing custom ROMs always read the install instructions whole first then install.

Nexus S won't boot to OS

I have the Nexus S from Telus.
It was rooted, unlocked, running CM7. However I've been having issues with it freezing and decided I want to go back to the stock rom.
I ended up downloading what I thought was stock ROM for my phone (Stock GRH78 Nandroid Backup in this Tutorial http://forum.xda-developers.com/showthread.php?t=884093) however after it flashed my phone, I ended up with a phone which was essentially stuck in Airplane mode, would not connect to Telus. I'm guessing that it has the wrong radio for my phone/carrier?
So then I ended up finding a zip file someone posted Stock-GRJ22-i9020A-unsigned which should have worked, I ended up flashing the zip file from recovery.
It said it installed fine. Rebooted, and now the phone just cycles the Samsung Loading screen endlessly.
I tried to go back to recovery, and it gives me yellow triangle with !.
Is there any way to flash the recovery image back to the phone?
I plug the phone in and the PC won't recognize a device.
I installed the Android SDK
Ran the command adb devices, no devices attached to the PC.
I tried fastboot devices - blank
I don't know how I'll be able to get files back onto the phone SD Card for flashing etc...
I had the exact problem two days ago...flashed an image that jacked my phone up. Wouldn't boot past the google logo. Sat there indefinitely.
Read this thread and see if you can get it work. In a nutshell, you need the PDA net drivers installed. Since PDA net can't install the app on your phone (because it's not booted into an OS) leave the install program in limbo and voila, fast boot will work. From there, push the recovery.img (google Clockworkmod recovery image), boot into recovery and you are off to the races.
This is, of course, assuming you already have a ROM image on your internal SD card you can flash to get back up and running. I'm not sure how to install a .zip image ROM if you can't gain access to your SD card.

Good luck, I know the feeling. It blows.
Ah, just found out how to install a file on a phone that won't boot.
You do need to flash CWM recovery first though.

Good news! I tried a factory reset/data wipe and rebooted the phone.
It doesn't hang anymore, all functions restored and the phone is working on Telus again!
I guess I had to format data, clear cache, before the flash of the rom.
So relieved.
Issue has been solved!

Root = bootloop on 5.0.1

Hi all,
So I'm far from a noob at at all of this (doing the custom android thing for years). But I'm not exactly constantly fiddling with my phone all the time anymore either. Basically I get a set-up that works for me, and I stick with it.
I've patiently been waiting to update to Lollipop. And today I did it. I did it by flashing the required factory images with fastboot.
AND IT WORKS. No problem. It boots. I go through the initial set-up. I can let it restore all my apps and passwords from the google servers, etc. So far so good.
My problem is that I cannot root. After I try, it bootloops (stuck at the Google splash, with my unlocked icon).
I tried to root before my first boot. I tried after the initial boot (before set-up and signing in). I tried rooting after setting it all up, and singing in, and letting google restore all of my apps. No matter which sequence I try, it will reboot a couple times at the first Google splash, and then fall back to Recovery.
(So, I'm on back on my rooted 4.4.4 nandroid, I think it's Mahdi Rom-- I forget)
Vital Stats:
Trying to install factory images of 5.0.1, all stock (system, boot (kernel), radio, bootloader)
Factory reset
(the above works fine)
TWRP 2.8.1.0
SuperSU-v2.40 (flashed via recovery)
Any ideas? Thanks for any help.
No, but could you try the previous version of SuperSU? Just to rule out the new version that I haven't tested please?
I updated to 5.0.1 earlier
Flashed all the img files exact userdata and then booted in to Android.
I then flashed TWRP 2.8.1.0 and used that to flash SuperSU 2.37
All that worked fine.. I then did a play update and SuperSU updated to 2.40
All working fine as far as I can tell. Apps needing root are working!

Try not doing that? When you go through the initial configuration, choose "Set up as a new device". Maybe the restore is somehow corrupting SuperSU?

It happens even if I try to root before setting anything up at all.
albert_htc,
Are you saying: I should also flash the stock recovery first. Then boot for the first time. Then re-flash TWRP. Then flash SuperSU.
I never flashed the stock recovery. TWRP was on already on it.
Thanks guys. I'll give it another rip (doing stock recovery, then flashing back to TWRP) sometime soon.

Yes, flash the factory image using the batch file so every partition gets re-flashed. Now I'm thinking maybe your recovery is corrupt.
Run flash-all.bat and when your device reboots, go through all of the initial configuration and download all of the Gapps updates. Once that's all completed, go ahead and route using TWRP. If you find yourself still having the same problem, try live booting TWRP to flash SuperSU.

I'm not going to flash over my user data, nandroids, app back-ups, etc. I'll stay with kit kat forever on my nexus 5 before I do that. Version numbers aren't that important. Hours wasted getting things set-up again are.
My recovery works fine. Both on kit kat and lollipop. My only problem is a boot loop when I flash SuperSU (via TWRP), on lollipop. I will try flashing stock recovery, though and then reflashing TWRP.

It's a tedious process, but it really isn't all that hard to back everything up to a computer, and you can do it easily with fastboot and a single command line.
Or what I'd recommend doing is just booting up, backing up all folders to a PC and then resetting and restoring later, backup apps with Titanium Backup (what I always do). A lot of us flashed factory images when Lollipop came out, so it isn't that bad once you start on the road.
Have you tried rooting from the bootloader via Chainfire's cf-auto root? I know I've read that sometimes rooting from recovery doesn't work properly, and that only certain zips will work. I've used the auto root each time (from stock fastboot flashing 5.0 & 5.0.1) with lollipop and it works fine. Link
Unzip and run batch file in bootloader. It will wipe everything if you haven't already unlocked bootloader (fastboot oem unlock). If you are already unlocked it won't wipe anything.

I just backed the /sdcard, to my PC. I just re-ran titanium.
I can deal with "/sdcard issues" from updating to lollipop easy enough. That's a 30 second fix. I can deal with setting up my email accounts to my email client app. I can deal with launcher settings, and all the other apps, widgets, etc. Those are things that I can slowly get back to where I want. They aren't critical. But yeah, very tedious.
I think "starting over" may be much more tedious for me than most people though. I run ssh servers and clients on all PCs, servers, and phones (disabling passwords and using rsa encryption keys for security). It's very nice, once I get it all set up in that I can access everything (from anything) very easily. I do need root for that though also.
But if I can't just hit a "restore" to get it all my ssh addresses, keys, fingerprits, etc back to where it was and then I have to: reverify new fingerprints, generate new keys, re-enable passwords to transmit new keys for everything, then disable passwords (for all machines) ... well... I just get very very grumpy.

Galaxy S6 only boots in TWRP

As the title already states my Galaxy S6 ( SM-G920F, 6.0.1, rooted) only boots in TWRP and I can't get out of that recovery boot loop. I already tried flashing the stock ROM but I get the SW REV CHECK FAIL DEVICE 4 BINARY 3 fail. Are there any ways to fix this, possibly without losing all my personal data(if not I'd like to know how anyways)?
I can access the download menu and I also tried wiping the Dalvik/ART Cache.
I tried this stock ROM: G920FXXU4DPIL, Switzerland(AUT)
Thanks for taking your time
EDIT: I haven't tried ADB since I'm not sure how to use it correctly and I don't want to screw up even further.
Hi mate that error means that the stock firmware you are triyng to install is a lower version than the one on the device, go online and find the most recent version, as for the data just boot to twrp make a backup of data partition, connect the phone to pc twrp as mtp turn on by default and copy the backup to pc, after the flash just reinstall twrp and restore.

SM-G610F Soft Brick happens after TWRP flash

Hello people,
I just tried flashing TWRP to my J7 Prime phone. Odin flash was successful and I could boot into recovery. I followed through normal procedure(data format and no-verity-opt-encrypt flashed). I did not flash any other zips and when i tried to boot back into System my phone didn't get through the Galaxy Prime logo. It wouldn't even show the boot animation. Before this happened, I did root my phone and everything was fine, I accidentally deleted google play once and also wanted to flash stock firmware so I did. After I flashed the stock firmware, when I wanted to root it again it would work after flashing magisk and booting into the system but after some time passes the apps one by one would begin to freeze and at last no app would even load. When i try to reboot at this point, the phone wouldn't boot back into the system anymore. It would get past the Samsung logo but the boot animation wouldn't even play as i was stuck in a black screen. I tried to restore with TWRP then, (Only restoring Boot, System and Data but I didn't wipe anything on the system before restoring. I think that this might be the issue but I just recently got into rooting.) but when i rebooted to use my phone it wouldn't get past the Samsung logo. The Samsung J7 Prime logo would show up, then 1-2 seconds pass and then reboot. This was a loop.
I was able to reflash stock firmware and get it to work normally. Since I can't risk bricking the phone as I can't get a new one after this experience I didn't flash anything again. Because after i restored with TWRP back then and now my phone bricking just because of a TWRP flash I think if I just give it some more tries (even with difference in procedure) it might just get hard bricked. I think flashing firmware so often might brick it. I really don't know but I can't risk bricking this phone.
The phone right now is OK. I just want to learn why this might happen, what would cause this and how to fix this. I will not flash anything because again I can't risk getting this phone bricked.
Just getting some information for me is enough as I am also curious about this problem,
Thank you.
