Hello
I was on TWRP 3.2.3-0, modified by TKKG1994.
I just flashed TWRP 3.3.1-0 and tried to make a backup of all partitions. There is an error saying "unable to locate '/preload' partition for backup calculation"
Is this a problem?
How can I solve this?

Hey guys
I am trying to install twrp 3.14.1 on my s7 g935f.
After doing the procedures to install via odin, I restarted the phone and it did not start in recovery mode, and now when starting the device it is only on a red screen.
I tried to reinstall the stock rom, but without success, how do I proceed?
Thanks

Did you end up fixing it or is it bricked? I'm contemplating trying this, but the last handful of messages on this thread and the lack of responses tells me to steer clear.

Edit: Went ahead with it and had zero issues. YMMV.

I've tried unsuccessfully to flash TWRP to my factory open SM-G935F in preparation for flashing the lineage Android 10 rom.
I did post a question here https://forum.xda-developers.com/s7-edge/help/boot-problem-successful-twrp-flash-t4175699 but haven't had any replies.
Currently I can 'successfully' flash TWRP and boot into it. I have tried flashing SuperSU and the no-verity-opt but I get a 'Failed to mount '/data' (Invalid argument}' message plus a load of red lines before the flash starts & on reboot I get taken to a 'Verification failed' screen saying 'Unable to restart your device. The integrity verification has failed. You need to reset your device to factory default settings. This will erase all your data'.
Download mode before reflashing stock rom reads:
Odin Mode
Download Speed: Fast
Product Name: SM-G935F
Current Binary: Custom
System Status: Official
FRP Lock: Off
Secure Download: Enabled
Warranty Void: 1 (0x030c)
SWREV: B:8 K:6 S:7
Fortunately, I've been able to reflash the stock rom via Odin each time (now done 3 times) and restored the phone to working with all data.
Is there a way of sorting the verification without a reset as I want to make a NAND backup 1st and if not will resetting sort out the verification issue?
Thanks.

Pls follow the respective rom thread for exact steps. Make sure you're following all steps correctly. Also make sure that OEM unlock is enabled in first place.

In short :

Install twrp in odin and boot directly into it from download mode without booting into phone>don't allow for system modification when asked in twrp and tick dont ask again > format data in wipe options and type yes > without rebooting flash magisk and then reboot (thats a standard systemless root procedure)

When flashing a custom rom you generally flash the respective rom zip instead of magisk and follow any additional/special mentioned steps in your respective rom thread. Again, pls read carefully everything before messing with your phone. Good Luck :)

Hello, I flashed the newest TWRP 3.4.0, and seems like whenever I boot into a freshly installed rom I can't mount anything in recovery mode anymore after that and it would require me to reformat again in order to mount any storage. May I know if there is something I can do to fix this?

Is this still a viable post? Its been over 4 years since its updated...
Yes. Because for those of us who are trying to do our bit for the environment and try not to be materialistic and so keep our phones for as long as possible, these "how-to"s are vital reminders of how to do things should we need to revert, maybe after a rebuild or something goes very wrong.

but I get a 'Failed to mount '/data' (Invalid argument}'
I got that too but it was after flashing supersu/customrom/gapps.
But if I want to wipe data, it tells that it's failing at mounting data too.

edit : So, in the recovery, try to format data. It worked for me I don't have the error message about data anymore ;)

Help!
My twrp has all of these new files and I cant flash anything unless it's right after formatting. It all comes back right after boot back into recovery and says I dont have any space to flash anything else.
I'm back in stock rom now no root.
twrp 3.5, odin 3.14, g935w8
Any way to fix this?

I have the latest twrp and I have encrypt my lineage is 18.1 but twrp is not showing the decrypt password. Any help.
Hi I am having the same problem. I am using TWRP 3.5.1_9.0 and have installed lineage 17.1. Everything is fine but when I encrypt the phone and boot into recovery TWRP is not able to mount the encrypted data partition. This was not an issue for me with older TWRP versions. Did you by chance find a solution to this problem?

I looked on twrp and I think there is problem with encryption because in fstab there is "encryptable=footer" but in lineageos there is "encryptable=/dev/block/platform/155a0000.ufs/by-name/TOMBSTONES". So lineageos is getting crypto footer from different location.

Please wait...
Hey guys, is this still the most up-to-date resource for OS 8.0 and S7 Edge SM-G935L (hero2lgelgt) ??
Or somewhere else better?
And is there a way around wiping device to unlock bootloader? I've picked up 3 of these devices.
Thanks :D

    Team Win Recovery Project 3.0.2-4



    This is for the International SM-G935F/FD/X, Korean SM-G935K/L/S, and Canadian SM-G935W8 Exynos models only! Do not flash on flat S7 or Qualcomm models!

    WARNING #1: Flashing a custom recovery to your device will trip the Knox warranty bit on your phone. Check with your mobile provider to see if they will still cover warranty on Knox bit triggered devices. If you understand this risk, continue on.
    You generally don't have to worry, as it's incredibly hard to brick a Samsung device, and physical damage warranties should be exempt from Knox triggering.

    WARNING #2: The Galaxy S7 stock boot image has dm-verity, which prevents you from booting if you swipe to enable system modifications!
    SOLUTION: Follow the full rooting steps below, in order, to allow system modifications without the risk of a boot loop!


    WHAT IS TWRP?

    Oh come on, you know what it is - don't try to fool me!
    In case you're serious, though...

    Team Win Recovery Project is a custom recovery for Android devices.
    It allows you to back up and restore your data, flash custom ROMs to your device, repair broken file systems, and root your device.

    DOWNLOAD

    You can find the device page here:
    http://teamw.in/devices/samsunggalaxys7edge.html

    There is a download link there, as well as instructions on how to flash it.

    I highly recommend using Odin to flash when possible.
    You can find a zip containing Odin as well as Samsung's Mobile drivers here:
    https://build.nethunter.com/samsung-tools/

    FULL STEPS FOR OBTAINING ROOT

    You can follow this video by Max Lee if you'd like: How to Root Galaxy S7 & S7 Edge! [Exynos ONLY]
    Otherwise, follow these instructions:

    1. In your ROM, go to Settings -> About device. Tap 7 times on Build number to enable Developer options.
      Transparent.gif
    2. Now go to Settings -> Developer options. (above About device)
      You need to enable OEM unlock, otherwise you might end up with boot problems or be unable to flash later on.
      Transparent.gif
    3. Extract Odin_3.12.3.zip to your computer.
      Transparent.gif
    4. Install Samsung Mobile Phone Drivers for Odin to find your device.
      Transparent.gif
    5. Download a .tar image of TWRP for hero2lte.
      Transparent.gif
    6. Reboot your device into Download mode. To do this, select reboot from the power menu and hold the [Volume Down] + [Home] buttons while your device reboots.
      Once you reach the Download mode warning screen, press [Volume Up] to continue.
      Transparent.gif
    7. Open Odin and place that TWRP tar file in the [AP] slot and disable Auto-Reboot, then press [Start].
      Transparent.gif
    8. Hold [Volume Down] + [Home] + [Power] to get out of Download mode and immediately swap to [Volume Up] when the screen blanks.
      If you don't see then TWRP boot splash try again from step 6.
      Transparent.gif
    9. At this point, you will reach the screen asking you if you want to allow system modifications.
      By swiping right, you will trigger dm-verity, and if you don't follow the next step you will be unable to boot!
      If you are going to root your device and follow the rest of these steps, then it is safe to swipe right and enable modifications.
      Transparent.gif
    10. If you want to be rooted with SuperSU:
      Download the latest SuperSU by Chainfire.
      Without exiting TWRP, transfer the SuperSU zip to your device over MTP* and flash it using [Install] in TWRP.
      You will need an external SDcard for this method, if you don't have one you will have to use adb sideload to install SuperSU.

      If you only want a bootable system partition:
      Download the latest dm-verity and force encryption disabler zip.
      Without exiting TWRP, transfer the no-verity-opt-encrypt zip to your device over MTP* and flash it using [Install] in TWRP.
      Note: This does not disable the forced encryption on Bxxx firmware, only Axxx firmware due to a change in vold by Samsung.
      Transparent.gif
    11. Go to [Reboot] -> [System].
      Transparent.gif
    12. Wait 2-5 minutes for your device to finish setting itself up.
    * MTP, known as Media Transfer Protocol, is the same way you transfer files from your PC to your device when booted into system.

    Hey guys :) :highfive:

    Some may know me, some probably not. It's not important who I am BUT I found that our device tree for TWRP builds is damn outdated (based on MM).

    I don't know if you faced this issue already, but some people couldn't mount /data partition in TWRP even though they removed encryption. Why this happens?

    Explanation:
    Samsung added quota support in their oreo update for the /data partition. Means a TWRP update with proper quota support is needed to get this new feature to work. Till now, many developer simply disabled this feature again on their kernels (so they can mount /data without issues on the old TWRP).

    What I did:
    I updated the tree with the latest files, kernels and so on. Including the above mentioned quota support.

    This TWRP version works on stock and supported oreo kernels. Older kernels (which removed quota to fix mounting problems) won't work here. Please advice your kernel developer to update his kernel with the changes :good:

    Download:
    Img file (flash via TWRP)
    tar.md5 file (flash via odin)
    39
    Reserved

    If you have a G935P, G935V, G935R, or G935A (aka the US Snapdragon models) your bootloader is locked. I will not be making TWRP for your device - it simply cannot happen. Sorry.
    Update: G935T users can expect TWRP for their devices as soon as T-Mobile convinces Samsung to unlock the bootloader - I already have a fully complete working build ready.

    You know who you can blame?

    THE DONALD!~~~~~~~~~~~~
    or Obama, I dunno, blaming Obama is getting kind of old guys, sorry.

    I will need someone to verify if features are working as this was just a copy paste of the herolte (non-Edge) device tree.
    Mainly expecting brightness slider to not work, so please if things don't work, join #twrp on freenode and talk to me.
