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?

It really is about TWRP failing to wipe

Issues with restoring recovery using TWRP-3.0.2-0

I'm having issues with restoring the factory image of stock Android 6.0.1, I'm using
 @Heisenberg guide to create the fresh back up image on TWRP-3.0.2-0. Once I create
the back up, I boot into the OS and perform a factory reset, when i do that the phone resets
into TWRP, and performs the wipe to the device, when i go to do the restore, it freezes
at about 39%, and reboots fully trying to enter the OS, but its corrupt due to TWRP restarting
in the middle of the recovery.
I did at one point upgrade to Android N, but reverted back to android 6.0.1 if that makes a difference.
TL;DR - Created a fresh factory image of 6.0.1 using TWRP, cannot recover with it, TWRP freezes at 39% every time.

What options are you selecting to backup/restore?

I'm doing a back up selecting the system/data/boot/vendor boxes, leaving everything else unchecked, and a second back up with only the EFS,
When i go to restore, I'm just using the first back up, leaving the EFS alone unless ever needed, and am selecting the system/data/boot/vendor boxes

I can only think that your backup is corrupt. Also, instead of booting into Android and performing a factory reset that way, just go into the advanced wipe section of TWRP and wipe only data. Maybe you'll just need to flash the factory images to get the phone booting up fresh again.

That's where it gets interesting, I've flashed the factory 6.0.1 image, then flashed twrp, created the back up again, did the advanced wipe as you said, did the restore again, and same result, at around 39% of the recovery the phone reboots and the back up gets corrupt. My main goal is to make sure this back up absolutely works before I root and start playing around with flashing xposed modules, but I'm unable to do a successful restore for the life of me.

I'm stumped, I really don't know why it wouldn't be working if you're performing the backup the way you say you are. Sorry I can't be more helpful. If it's any consolation, a backup probably isn't strictly necessary because you can always get back to stock by flashing the factory images.

I'm stumped too, I've been able to do this effortlessly in the past with this phone, my Nexus 9 and m8 GPE, it wasn't until I upgraded to N and reverted back to 6.0.1 this started to happen. I've even gone as far as trying different versions of twrp, but have had the same result.
I'm just worried in a worst case scenario I'm away from a comp, something crashes and I can't do a restore via twrp, I could be SOL until I get to a comp with adb.

i had a similiar problem , but when i got into the stock image , i went into settings and did a factory reset from there , no worries your BL stays unlocked , once thats done get whatever apps you want back , disable fingerprint /security junk , then boot into bl just like the guide says , youll be able to fastboot install recovery , (boot back into bl, then scroll to recovery and start a gain) then make your backups yor OG & EFS , then reboot , get su reboot into recovery install and yould be be fine , i think you can also try fastboot format userdata , as well

Just keep a ROM zip + gapps on your phone at all times, if you run into trouble you can flash that.

That definitely makes sense , i always dk that

Stuck in spinning circles after updating to OOS 5.0 Oreo OTA

Hello! I just updated to the latest OTA of OOS 5.0 and now the phone is just stuck on the screen where the white dots spin around I tried clearing cache, wiped "System settings" via Oxygen Recovery and no luck. I sideloaded the zip to my device and flashed it over the one I had on it previously. I followed this guide https://forum.xda-developers.com/oneplus-5/how-to/guide-restore-data-stuck-bootloop-n-o-t3724515 without any results! This is ridiculous. I just wanted to update to Oreo. Here are my phone details: https://imgur.com/a/n4rtR I am unsure what to try next. Should I wipe /system and flash the previous ROM zip file and try that? I can see my files but they are completely encrypted thanks to OOS, but only can I see them in Oxygen Recovery; TWRP shows nothing. Suggestions would be appreciated, thank you.

Had the same problem, had to format Data partition to get it working. Lost all data though

I was on OOS 4.5.15 with Magisk root and TWRP. Last night, uninstalled Magisk and I flashed stock recovery to update my phone. Even though I cleared cache and Dalvik, boot loop happened.
Only after a full reset, the phone boot normally. Since I had all important files backed up, I did not loose anything but it still bothers me. There should have been a more streamlined update process.

I completely bricked my device with the update, so i used this tutorial : https://www.androidexplained.com/oneplus-5-unbrick-return-stock/
I lost all my data but now it work like a charm and i was able to update properly to Oreo

You have to do a full wipe (system, data, internal storage, and both cache) when going from Nougat to Oreo. That is the only way.

If so, how could they offer an OTA for customers? Don't get me wrong, I am just wondering.

From what I know, you have to be unrooted and on stock recovery for that to work.

I had unrooted my phone using magisk uninstaller and flashed stock recovery. It has something to do with encryption, but I am not quite sure.

I was unrooted and having stock recovery, still got bootloop. OnePlus basically messed up.

Stuck with a OP5 with no OS

Hi everyone,
I have been happy with the Marshmellow version the OS since I bought my phone when it came out (Unlocked, Encrypted). I have performed one update since I had the phone. Today, after seeing the latest posts after not being on this site for a year, I decided to make the move to upgrade to OOS 5.1.0!! Why not, nothing else going on this weekend. I upgrade TWRP to 3.2.1-1, I make a full backup, I follow the upgrade instructions... it fails with the continuous spinning balls on reboot. I Do some research... oh, it is "challenging" to upgrade but possible. No big deal, I will just restore my backup and try again at some other time. My backup restore fails Error 255, I try the fixeS I found such as unmounting data... No Luck). Can not restore the data partition. I guess I should have decrypted everything prior to backing up based on what I read later.
I at least backed up my SD card using adb prior to all this, so I decided to just reinstall ANY OS to get my phone running again for tonight. Well I have not had much luck. I downgraded TWRP to 3.2.1-0, I have tried installing:
OnePlus5Oxygen_23_OTA_033_all_1804110400_eb1766 - Originally installed with not errors but phone reboots back into TWRP after a failed 1st reboot. (I do get a "failed to mount /vendor")
lineage-15.1-20180423-nightly-cheeseburger-signed with Gapps (Gapps failed with I think a error 7)
I was messing with the data partition, wiped, formatted, etc. I am sure this is some of the issues. One other thing is that TWRP always boots to the "keep System Read only" I find this strange and had never seen before. I select to allow modification, but it seems like nothing changes on reboot.
At this point I would just like to get a stock OS image on the phone. IS there something I am missing?

Sounds good, let me give it a try.

I've been thru this already. Here is the simplest way to get your 1+5 back to work, while having the latest LineageOS installed. It takes a bit of time and patience, but it works:
Using fastboot, reinstall TWRP 3.2.1-1 (or newer, if any)
Wipe all partitions, namely Dalvik/ART cache, Cache, System, Data and Internal storage
Sideload the latest OOS (version 5.10 or later, if any) with Android 8.1. This version will be OK for LineageOS 15.1 and you will no longer have that stupid error 7 when installing LOS 15.1
If OOS boots into recovery and asks for passwords or PIN or schema ... click on the "forgotten" link. OOS Recovery will then remove encryption and wipe out any data that was left.
Reboot phone, and start OOS session. Do not use any security stuff (PIN or schema or whatever) that would encrypt the phone. At least not now - If necessary, you will add it at the end of this whole process.
Once OOS is working, reboot to Bootloader. Since TWRP has been erased with OOS default recovery, you will have to reinstall it.
From TWRP, wipe Dalvik/ART cache, Cache, and Data partitions. This time, do not touch System or Internal storage
Sideload Lineage OS latest version. If you need to use Google Apps (e.g. Open Gapps), sideload it now before rebooting
Reboot (you might have to reboot twice, don't worry about that).
Once booted in LineageOS, do whatever you like - add accounts, root phone, etc.
Enjoy! (you may want to shout "Vive la France!", well ... don't hesitate!)
Sorry for my poor English. If anything here is unclear to you, please let me know.

I Have no idea what happened. I came home to start working on my phone, powered it up, and boom I have Android 8.1. Ok, Whatever...
Now I wonder if I should go for lineage or not.

It all depends on how important privacy is to you. If you don't care, then stick to the original OnePlus firmware. If you do, then switch to LineageOS.

[Suppot] OnePlus 5 doesn't boot after OTA update

Hey,
I didn't updated my phone for quite some time and today I had some free time and I decided to update it to the latest version. I performed the first OTA update, and the process wen't really smooth. The phone booted after a few minutes, however it told me there's another system updated so I installed it as well.
However, after installing the second OTA update, my phone never booted again. it stucks in bootloop for a few minutes and then just boots to recovery.
I don't really know what to do, and although most of my data is backed up I really want to avoid wiping all the data.
The phone was never rooted and has stock recovery. How can I make it boot without wiping all the data? I did try to wipe cache already and it didn't help.
I see that there is a method called 'adb sideload' but I want to be sure it doesn't wipe data and to know which zip I should give it... Thanks!
