Are you using a kernel with dm-verity disabled?

Did you let TWRP stay R/O if the above is not the case?
[Galaxy S6 Original Android Development] Orginator:
I am using a stock setup, haven't touched anything, aside of installing TWRP. To be more exact:

http://www.sammobile.com/firmwares/download/51441/G920FXXU2POGJ_G920FVFG2BOG2_VD2/

What do you mean by R/O?

Edit 1:

PS: I flashed the firmware, so can boot now just fine

However when I try restoring data from the backup, I get a bootloop afterwards. When I restore system, it yet again hangs on boot samsung logo.

Edit2:

I've manged to restore my data as following:

Restore (only) data via TWRP, then flash official firmware via ODIN, afterwards the phone booted and everything was there :)

Please help!!!

I rooted my S6 CF, ok. Then, I downloaded the suggested TWRP Manager from Google Play, downloaded the Recovery 2.8.7.1 and when I did the install Recovery, it said some error... Didn't make it the install... BUT it asked to reboot to see if it worked.. and now my S6 is stuch in Galaxy S6 logo... I'd like to enter in download mode, but I can't.. because it's frozen in that logo... It can't turn off to enter in download mode.. if I force to reboot, it comesback to the same logo frozen after reboot... So.. plz.. what???
[Galaxy S6 Original Android Development] Noxxxious:
Holding the volume down + power button + home button should bring you in download mode..
[Galaxy S6 Original Android Development] cyberdelia:
Almost.... If anyone has the same problem, it's what is going on:

For entering in download mode, you mus first turn off the phone... BUT I can't turn off the phone.. the power button doesn't respond. So... I read about how to do a reset (power buttton + Vol Down for 7 seconds). So, it reboot, but it's still stuck in logo screen, and Can't turn off.

So, I added the home button... FOR SEVEN SECONDS (Power+Home+VolDown) and it enters to download Mode..

So, I enter to Odin... it Added, I selected TWRP tar, and after the first reboot, it's stuck again in Logo screen... So... ¿Does anybody knows where can I get the stock firmware to flash thru Odin? please?
[Galaxy S6 Original Android Development] Noxxxious:
Depends on which model you have, but take a look here: http://samsung-firmware.org/
[Galaxy S6 Original Android Development] bigbiff:
If you modify system AT ALL in 5.1.1, stock will never boot for you. You have to make sure to keep TWRP in read only mode (R/O) at all times if you want to keep stock. Also you have to just backup the system-ro version which basically does a dd of the entire partition.
[Galaxy S6 Original Android Development] bigbiff:
Which image are you flashing in odin?
[Galaxy S6 Original Android Development] cyberdelia:
I got stock firmware: G920IDVU1AOBQ_G920IUUB1AOBQ_G920IDVU1AOBQ_HOME.tar.md5 (that's the one I had before starting flash twrp from here: http://samsung-updates.com/details/43592/Galaxy_S6_SM-G920I/SM-G920I/TTT/G920IDVU1AOBQ.html

I'm charging a little now, because it drained everything (because I dould'nt turn off the phone)

==== IMPORTANT LESSONS TO SHARE ====

Oh, my god... 15 hours suffering. So, things I have learned after looking for houndred of sites:

If you are not sure of fabrication date, don't flash TWRP. It's not compatible with all firmware even the same G920xxx model

Certainly, in any case, don't use TWRP Manager from Google Play Store. It make a very stupid and VERY risky question that a normal user CAN NOT know

Until TWRP be fully compatible with all firmware, stay in CF-Root only (if you are in Android 5.0.2). And use only ONLY v3.10.6

According to many sites, 5.1.1 bootloader is not compatible with finger reader and you can't downgrade after you flash the bootloader.

Before trying any change, first look for your stock firmware exactly for your phone, for unbricking when anything goes wrong

Always Do a Backup of your IMEI and EFS partition with free tools available in Google Play and save the backup in your PC

By the way, I finally unbricked my phone Odin the stock firmware.
[Galaxy S6 Original Android Development] Orginator:
But I did not modify the system. Just backup and restore. Unless restoring means modifying.
[Galaxy S6 Original Android Development] bigbiff:
What version of Android did you have and what TWRP version did you flash to your 920i
[Galaxy S6 Original Android Development] bigbiff:
If you let TWRP mount system read/write ever, it will never boot again with stock kernel.
[Galaxy S6 Original Android Development] cyberdelia:
Android 5.0.2, TWRP 2.8.7.1, Odin 3.10.6
[Galaxy S6 Original Android Development] bigbiff:
Hmm. have you tried under 5.1.1?
[Galaxy S6 Original Android Development] cyberdelia:
I couldn't get to 5.1.1 I got stuck trying to Odin TWRP when it got soft-bricked
[Galaxy S6 Original Android Development] bighleo114312:
I had those issues first with my 920t1 (metropcs). It happens to get bootloop at logo because after we flash twrp we need a custom kernel like unibase. I used simplkernel. And it boots normal. If i only flash twrp its a bootloop. I had to use odin like 4 times cause was the only way out. At last i did flash twrp after that flashed arcadia and unibase v1. And havent changed rom.

[Galaxy S6 Original Android Development] :
!! Formated /data on encrypted S5 and it still asks for Encryption password

... not to mention the password no longer works and now my phone is soft bricked.

Why is it behaving this way? I want an encrypted phone for protection not for hassels like this.

I formated /data because of a bootloop after fussing with link2sd. That was annoying but the fact that format /data did not remove encryption and allow me to boot into the OS is much more annoying as it requires me to bring a laptop wherever I go in anticipating events like this one where I have no choice but to flash stock and start over.

[Galaxy S6 Original Android Development] evandro.oliveira:
I forgot to turn off, what can i do to fix it?
[Galaxy S6 Original Android Development] nixholas:
Download a full firmware tar for your phone, and flash it. That's the only way to unbrick it.

Once you're back, DO NOT do the same thing again. Make sure activation lock is off before you continue doing anything else

I had a strange issue when I tried to install TWRP...

I took my stock G920TUVU2COF8 S6 and ODIN flashed TWRP 2.8.7.1 and immediately after I was no longer able to boot, it'd say SAMSUNG Galaxy S6 in a loop. I flashed stock from ODIN and it rectified the bootloop but got rid of TWRP.

Anyone know what I did wrong? Would replacing the recovery.img in the stock ODIN flashable with TWRP recovery.img work?
[Galaxy S6 Original Android Development] xillaron1:
Does TWRP 2.8.7.1 support f2fs conversion? I can't seem to find it.
[Galaxy S6 Original Android Development] bighleo114312:

Hey there, I got a huge problem.

I wanted to flash the newest Adam Kernel and therefore I flashed TWRP over Philz with the TWRP Manager App. But now there aren't any files shown when i want to select the Adam kernel's zip in TWRP. TWRP even says that data couldn't be (un-)mounted. Even if I try reflashing TWRP with ODIN, it doen't change at all... I also cannot flash any .zip via ROM Manager App or similar.... There's no way. Even the adb sideload function in TWRP doesn't work.

Does anybody know a solution?

Thanks in advance!

after flash reboot with vol- / home / power and press instantly vol + / home / power to prevent the system running stock recovery again, it works

Wiping cache doesn't work for me. Tried several things, flashing stock recovery and TWRP, wiping cache, but I can't get deep sleep to work.
[Galaxy S6 Original Android Development] Alarand:
Deep sleep did not come back for me after just wiping cache. Here's the order of what I did

-Root & Flashed TWRP via odin, cleared cache in recovery. (Deep sleep lost)

-Flashed stock TMO recovery with flashify, cleared cache in recovery. (Got deep sleep back)

-Flashed TWRP via flashify and wiped cache again. (Still have deep sleep)

This isn't a solution, this is just what worked for me.

The only thing to know with the link I quoted directly above, is that is also flashes a modified kernel (with selinux removed) so you would then need to reflash stock kernel if you wanted it back at stock, but the TWRP reported as working on 925 Edge, and no deep-sleep issues.

[Galaxy S6 Original Android Development] bigbiff:
Deep sleep means the processor shut down and isn't running at any speed. This to me means some application is running keeping the kernel alive. More likely something checking for modified recovery, but without any real evidence everything presented so far IMO has been speculation.

FOR ALL YOU HAVE PROBLEM INSTALLING THE LASTEST TWRP​

open odin and UNCHECK auto reboot DONT LET REBOOT, the reboot by yourself the device directly to recovery... if auto reboot enabled, the stock rom will REFLASH the stock RECOVERY

im just install the TWRP

Read This from twrp site:

Note many devices will replace your custom recovery automatically during first boot. To prevent this, use Google to find the proper key combo to enter recovery. After typing fastboot reboot, hold the key combo and boot to TWRP. Once TWRP is booted, TWRP will patch the stock ROM to prevent the stock ROM from replacing TWRP. If you don't follow this step, you will have to repeat the install.

Whatever method I choose, I CANNOT get TWRP to Install. I Tried Via Flashify, TWRP Manager and ODIN, and everytime, on reboot, the Boot screen comes on, the soft buttons flash, and the screen blinks and shuts off, occasionally vibrating when the screen is touched.
