Cannot wipe with TWRP

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?

Just got RMA, can't disable force encryption

Just got my RMA, so of course I instantly unlock, root, and go to disable forced encryption and i keep getting a password error, my only pin i've ever used won't work, so I flashed factory, reset it up, made sure i didn't use a pin or anything, tried again, still asks for a password and won't accept mine. Am I missing something or is the fact they sent me a remanufactured phone screwing me because of the previous users pin?

What TWRP version are you using? Are you on the newest 3.03? If not that's more than likely your problem.

OMG I'm confident it's 3.02. So I need to update that before I try the decrypting thing. I need to go root, twrp 3.3 then unencrypt ?
Thanks man I wouldn't ahve thought of that .

Just download the updated TWRP from this link. Boot back into recovery and choose flash IMG instead of zip. Install to recovery partition and then reboot. You should be good to go.

same nonsense. Went from clean, rooted, flashed TWRP 3.03, tried to flash noencrypt kernel and it's asking me for a password I don't have ... . should I try making my own password next time I reflash stock and see if it like overwrites it ?

found something on a N6 thread that says wipe user data and it should work .

Yeah that will work and shouldn't be an issue backing up everything with a new phone. TWRP should be able to read an encrypted device though as long as you gave it permissions to change system. No kernel will decrypt a device but most do not force encrypt.

I had a similar problem with TWRP 3.0.3-0 when I tried to restore a backup. It asked for a password, which has never happened before. I couldn't access my backup or any of my data or boot up. I had to restore stock. Clearing user data did nothing.

I was not . Just trying to disable force encrypt root and get PN back on it . Wiping worked for me. Also on 3.03, but that alone didn't solve, had to wipe . May be because I was using WUGS instead of manually doing it . Not sure, but it worked .

Hey, I'm running into the same problem after an RMA. I'm currently on stock unrooted 7.1.1 and want to flash custom rom but want to disable encryption beforehand. Can you advise proper wipe steps, or is this correct?
- unlock bootloader
- restart phone, enable developer options for USB debugging
- fastboot twrp-3.0.3-0-angler.img
- factory reset
- wipe everything (all checkboxes) including internal? (will this format with no encryption?)
- wipe system, data, cache
- push ROM (PN), Gapps, SuperSU-v2.79-201612051815.zip to phone via ADB in TWRP
- flash ROM (PN), Gapps, SuperSU-v2.79-201612051815.zip
- restart
Or is there another way to decrypt data or is it not an issue when clean wiping a new ROM?
Thanks and appreciate any help.

You need to Format Data, Not Wipe to decrypt. It WILL wipe EVERYTHING so make sure anything in internal storage you want is backed up.

Thanks for confirming, I wasn't aware that there's a difference between Format Data and Wipe Data. After formatting data, I should be able to sideload the ROM, gapps, etc back via TWRP right?

I always try to keep an emergency folder on the PC with the minimum needed to copy back to the phone through recovery. In my case I keep a copy of pure nexus, dynamic gapps, supersu and elementalx. That combination never fails to boot and I know it well enough to get back in business in short order if it all went to hell. Do what's best for you.

Unable to remove encryption

Hi,
I have a galaxy note 4 that isn't rooted but has TWRP 2.8.5 installed. I wanted to factory data reset the device, however, I was getting the error that it was unable to mount /data. I read on XDA that I had to format data. I clicked on format data and typed in yes.
I got the message "Formatting Data using make_ext4fs function. You may need to reboot recovery to be able to use /data again. Updating partition details ... done". I see the status as "Data Format Complete Successful".
I rebooted the device, and I know the OS loaded, but I was greeted with the error "Encryption failed, cannot decrypt your device storage. You need to reset your device to factory default settings". And a reset device button. I click on the reset device button, it boots me to recovery and runs a script and again reboots to the previous error.
I tried to factory data reset it now, although it showed as successful, I was directed to the same error.
Can you please advise what should be done?
Thank you

Any update? Thanks

Bumping

You will need to take your device to a Samsung Service Centre and let them take a look at it. However seeing as you have TWRP 2.8.5 there is a chance that they won't help you. What you should have done is decrypt your device then perform a hard factory.

Are you able to go to download mode and reflash OS?

My device is not rooted. Will I be able to reflash a new OS? Please let me know. Thanks!

No root required and it will not void your warranty and will not trip knox. You can download the the right version of OS from Sammobile site and flash it via odin in download mode. There are several guides available for it.

Guide to update rooted phone?

Hello, I have my phone rooted and would like to update to NMJ51B, but I'm not exactly sure how to go about it and don't want to risk bricking my phone again! What would be the exact process to go about this? I'd like to do it without wiping my phone if possible. While I love having root, OTA updates seem to be a real headache. Any help would be appreciated!

You have to re-flash the stock boot.img from your current build via fastboot, then you should be good to go. Check for an update in the settings and update. Shouldn't have to wipe anything
You can get the boot image from the essential site or from the firmware dumps in the rom section of the essential forum. I hope this helps!

Ok, I was thinking I'd have to wipe the phone to flash a stock image. Thanks for the info!

Uh, the very first thing it says when flashing the stock rom is "erasing userdata." Are you saying it's NOT going to wipe my phone?
Annnnd, it wiped everything, including the backup I created with TWRP. For future reference, does anyone have a step by step that does NOT wipe data?

You don't have to flash the whole package just the boot.img. But it sounds as if you already wiped. I should have clarified. In the guide to how to root your essential, if you read through, others have explained how to unroot without wiping.

HELP with resetting wifi config on V11.0.0.IN11BA

hey guys, i really need your help urgently.
i just finished setting up my OP8Pro to my needs and then i restored wifi networks from my Titanium Backup from Android 8, i booted and it won't boot anymore.
i get a FATAL EXCEPTION IN SYSTEM PROCESS: WifiHandlerThread...
so now i need to reset these settings via stock recovery and i already modified my recovery to enable ADB but i can't access /data
anyone has a hint for me how to access /data and where to find the wifi config on Android 11?
it's not stored in /data/misc/wifi anymore :/
thanks a lot in advance!

You can reset WiFi within WiFi settings in settings.
But I would probably just clear data on the app you restored either in settings/apps or simply via titanium.
If it still fails then boot to recovery and wipe system.
Your storage will remain unaffected.
You could also try safe mode, power off and hold vol up and down as soon as you see the bootloader warning
Fyi I wouldn't bother restoring WiFi passwords like that, there's other ways of doing it.
Google can back these up for you for example, there are apps which can do it like swift (I think can do it)

thanks for your answer but unfortunately i can't boot anymore and i can't decrypt /data anymore even after reflashing stock recovery.
what's the best way to flash via fastboot to preserve data?
thank you!

You'd have to grab one of the fastboot ROMs then flash.
Why can't you open recovery? Isn't your pin / password being accepted?
If it's not and fastboot installation can't be done then honestly I'd just MSM your current firmware..it's easier than fastboot tbh.
You'd need to bootloader unlock after but this is going to wipe everything anyway.

my bootloader is already unlocked and i was rooted on 11.0.0... i can boot into fastboot and recovery but i'm not prompted my unlock pattern.
this was working before testing adb integrated recovery and restoring stock recovery...

I don't get you mate??
I'm saying that if you use the MSM tool it will lock your bootloader so you'll need to unlock it again.
In regards to your recovery if you can get to it then choose English, then wipe, then system, then wipe system.
That will get you back like I said in my previous post.
If it's not asking for your pin/password (there is no pattern)
Then you're fine
I've not used that recovery but I don't see a point in using it

sorry i haven't used MSM yet so i didn't know it'll relock the bootloader but i'm more familiar with fastboot flashing so i'd like to stick with that also because i read of problems with the fingerprint reader when relocking the bootloader.
i thought i could delete reset the faulty wifi config via adb by using the adb-enabled stock recovery but i wasn't able to mount /data with it since it's encrypted and it's not asking for my pattern to decrypt it.
neither the stock recovery is asking for it now...
i don't want to lose my data hence i'm looking for a way to get it back running without completely reinstalling.
do you think it could work by only flashing system partition via fastboot?
thanks man!

Use the thanks button buddy
I think you've certainly got a shot at it and what's the worst that can happen?
Did you actually try to wipe system in recovery? That would be my way to go.
MSM is extremely easy but I understand not wanting to lose storage.
That being said if you're correct about decryption then it won't matter anyway

You're very welcome mate, I've done the same a few times..it's not that much of a loss really, a lot of apps pick up where they left off and if you do have titanium then your back ups are retained.
Glad you're sorted.
PS: this would have had the same effect that installing system would have had, only this time you get a clean slate
