Hi,
I have G935F, installed TWRP 3.0.0.0 and rooted, WITHOUT wiping. System boots correctly, but I cannot do factory reset or wipe with TWRP, because I got some messages like "Cannot mount Data" and "Failed crypto loader". I understand that it has to do with encryption. Can someone please enlight me, and give me tips about the issue?
Thank you

You have to download dm-verity and force encryption disabler from here , put it to SD card, reboot into TWRP, FORMAT DATA (not wipe) and flash that file (dm-verity and force encryption disabler). All your data will be erased.
No way to unencrypt without loosing you data for the moment(
"All your data will be erased" means that after boot I'll find a clean system installation (as factory reset)?
I hope not to be posing stupid questions, I'm completely new to this world
Thank you very much
Yes just as a factory reset

No, you cannot perform a backup, because your data is encrypted by default and the only way to disable it is to format your data.
I have a unique problem. I have a HTC Desire 612 from Verizon and I decided to revive it to playe PoGo. But it was stuck in a boot loop and I couldn't get any custom ROM.
Finally a gentle soul here gave me the stock rom and I flashed it vide TWRP and played PoGo for weeks. Then yesterday the phone bro led and when it came up it was stuck in a boot loop.
So I decided to flash the stock ROM again. But before that I tried to factory reset. I could go to TWRP, select wipe data, enter yes and the wiping was successful, then clear dalvic and cache and system beforehand finally I flashed the stock ROM.
Surprise surprise is NOTHING happens. The phone boots without the apps telling me they are installing. Then I get back the exact same data in my phone including my selected wallpaper and apps. Before I can do anything the phone restarts.
Point is wiping and restoring the stock ROM does NOTHING to the phone yet the processes are successful. Can somebody help?

Hey guys,
I've tried to flash DarkSide preFinal on my Atrix, now the phone is stuck on "Unlocked, Dual Core"-Screen.
Here's what I did:
Downloaded latest DarkSide and saved it to internal SD
Factory Reset via Recovery Console
Wipe Data
Wipe Cache
Wipe Dalvik Cache
Flashed the zip file
the process seemed to go through just fine, now when I'm trying to boot the phone it is stuck at the "Dual Core"-screen
Any ideas on how to solve this? I tried to factory-reset and wipe several times, still stuck
Any help is appreciated!
1. Do you have an unlocked bootloader?
2. Are you using a CWM-based recovery?
If you have answered yes to both 1 and 2 then:
3. Have you tried flashing the zip from the external SD?
4. Did you try to flash anything else after flashing the ROM while still in the same recovery session?
(If you answered "Yes" to #4 then re-flash the rom by itself and boot at least once before flashing anything else)
EDIT: Ignore question #1, I just realized you mentioned "Unlocked" on the boot logo.

Thanks for the quick reply.
I reflashed with Wet Dream from the external SD (newer is always better, right? ).
Everything is working now
Seems like being a great ROM.

how long did you let it sit at the loading screen?
Usually when I have boot loops, I let it sit on the loading screen for awhile(2-4 minutes). If it still doesnt boot, then I do a battery pull, and then usually after that it boots.
And if it doesn't boot just reboot into recovery mode, wipe cache, data and dalvik and reinstall the ROM again.
Sent From Rob's RP-Hybrid Atrix.
When installing any new rom, it can take a while to build up the dalvik cache again. I've had it take up to 10 min before. Best to just walk away and come back and check on it.

Similar situation here. I run on my spice uno on stock Android with all security updates. Recently my device entered into boot loop when I restarted it.
Things I tried -
1. Wipe cache, restart
2. Factory reset, restart
I did these steps by entering into recovery mode with both sims and memory card attached.
Then I removed everything and again tried above steps.
At last I also tried, mount system, wipe cache, factory reset, restart (in sequence)
I don't want to root my device and loose ota updates.
Please suggest a way out.
Thanks in advance

Same problem for me any one suggest a solution for this.
Hi guys, I need your help.
I have a Samsung Galaxy Tab A SM-T550 and I wanted to wipe its content. The tablet was rooted, and it had TWRP as recovery.
I rebooted to recovery and wiped System (probably the guilty), Data, Cache and Dalvik with TWRP, then I pressed "reboot" and it told me "no os installed".
So I tried to flash a custom rom, the JazzROM, but still it's stucked at the logo screen (it restarts itself after 10/15 minutes and then again stucked).
What can I do to solve?
I'm able to access to TWRP.
Thanks!

Download and install the stock firmware.
I suggest in future you use TWRP for its intended purpose. Make a full device backup prior to modifying anything.

Thanks ashyx, I have flashed the one that I found on Sammobile, and now it's working
And yes, you're right about the backup, I forgot to do it
So I flashed the latest version of TWRP on my s7 edge SM-G935F
And I got the error "failed to mount data" I formatted my phone and I didn't see the error again, I rebooted my phone and everything was working fine then when I wanted to root my phone with Magisk, i went back to TWRP recovery and I got the error again, so I formatted my phone again and rooted it, then I rebooted my phone and I said that the data is corrupted that I should reset my phone to factory reset, I went back to TWRP recovery and still get the same error.
It's like the TWRP recovery is not stable and it also reset immediately you leave so that when you come back you must format your data or factory reset it before you can use the recovery.
Can Anyone help fix this problem, I don't want to wipe/factory reset my phone every time I go to recovery. What if I make a mistake and go to recovery? That means I must wipe/factory reset my phone before using.
Please help!

If it's telling you "failed to mount /data", go to wipe > format data and type yes. Factory reset, do your things and then reboot back and install what you want, you shouldn't get the error anymore.
But later if I want to flash another thing like a mod, I have to wipe data again

Nono. Wipe data once, factory reset in twrp, and you don't need to wipe data again after that. Only wipe it once after you format data.

Hey folks. I'm hitting a brick wall trying to figure out this issue and I'm hoping someone will know how to fix this.
I have a Galaxy Tab A 8 (SM-T350) that I rooted and successfully flashed with first crDroid, then Lineage (both Android 9.0) using TWRP. I had made a backup before attempting this just in case I wanted to revert to stock.
Well, that didn't go as smoothly as I was hoping. Ever since trying to restore my backup, I've been stuck on a continuous boot loop that I can't seem to fix.
I keep getting "E:failed to mount /efs (Invalid argument)" and "dm-verity verification failed. . ." no matter what I try. I've googled the error and tried every solution suggested but I still can't get it to boot.
Any help at all would be greatly appreciated. Thanks.

Ignore the EFS error its probably a red herring. Your issue is dm-verity.
3 ways around it. Return to complete stock, including wiping the data partition or flash root (magisk suggested) or disable dmverity using one of the zips out there.

Thanks for the reply ashyx.
I've done two of the three things you suggested. I've tried returning it to stock using an image matching my exact model, and I've tried disabling dmverity. I've also tried rooting it but using a method other than magisk.
The flash seems to go well enough, but then I get stuck at the Samsung logo whenever I try rebooting into the system.
I've tried waiting, thinking I'm just being impatient, but it doesn't ever seem to get past the logo. I've tried googling ways to fix it being stuck on the logo but nothing I do seems to work. Is there any other way around it?
Side note: I've been able to flash Lineage OS again and might just have to stick with that if I can't flash it back to stock. Do you know any resources for replacing the default apps? I've tried GApps but I was wondering if there's a similar Samsung installer?

You need to wipe the data partition, aka factory reset before or after installing the stock firmware then it will take anything up to 15 mins to boot.

I've tried leaving it for a few hours in hopes that it would boot, but unfortunately it stays stuck on the logo.
Is there a way to check where or why it's getting hung up?

Did you back up the efs partition with twrp?
If so try restoring it.

I did and I have been restoring it.
So far, this is what I've attempted:
Flash TWRP (twrp_3.1.0-1_sm-t350_18317.tar using Odin3 v3.10)
Reboot into recovery
Wipe everything from tablet
Format tablet
Reboot into download mode
Flash stock image with Odin
Reboot into recovery
Wipe dalvik cache
Restore backup (including efs partition)
Wipe dalvik cache (again)
Reboot
Get stuck on Samsung logo (left it for hours with no change)

Don't restore everything just EFS No need to keep wiping dalvik it serves no purpose when formatting or wiping the data partition.
Also FORMAT not wipe the data partition (note this wipes internal storage)
If it still doesn't boot install the combo firmware. Let it boot, factory reset from settings then reboot to download mode and install the stock firmware again.
