Hello,
I hope someone will be able to help with this, although it is very much a case of user error! I upgraded my G3 to Marshmallow using the steps detailed here:
http://forum.xda-developers.com/lg-g3/development/stock-d855-30b-images-kdz-flashables-t3282012
It all worked perfectly until I decided to encrypt the handset. The encryption process worked as expected, but as I always did on previous Android versions, I used the CryptFS Password app to change the encryption password. The app advised that it was unable to change the password and that I should run the command via shell, which I did and it seemed to work. The problem is, I changed it to an alphanumeric password and my lock screen is just a numeric PIN, so upon reboot it prompts me to enter the password to decrypt but only allows me to enter numbers.
So, I kicked myself for not changing the lockscreen from PIN to password before rebooting, but figured I could just wipe/reflash and start again. However, when I reflash, I still get prompted for the encryption password at boot. So I figured I'd just enter the password wrong 30 times and factory reset the device that way, except that doesn't work either. It says it's going to reset, reboots to recovery (TWRP 2.8.7.0) and says it has reset, but then boots back to the encryption screen again (which now advises that I am -5 of 30 attempts!!).
Flashing CM13 or 12 works fine. I have settled on CM12 at the moment because it seems to be a bit more stable, but I'd ideally like to get back to stock Marshmallow. Is this possible?
I have tried wiping all partitions and data from within TWRP, and formatting partitions, all to no avail.
Is there any way I can reinstall stock Marshmallow?
Trying flashing marshmellow KDZ and it should reset everything
Let me know how things go

try booting into twrp, go into command terminal, manually format data partition using command line, then reflash cm12 and wipe cache and dalvik (you may not need to reflash it but why not if you are going back to mm)
if your partitions are the same as mine this is the command you want to run.
mke2fs -T ext4 /dev/block/mmcblk0p44
make sure you don't format the wrong partition check that your variant has the same partition (grab an app called diskinfo and click on data partition then alter the last parameter to w/e ur data partition is)
mmcblk0p44 is the paramater you want to change if yours isn't identical. this should reset encryption as data is the partition that gets encrypted.
after all of this use a guide to install marshmallow (kdz or something)
(when i encrypted my data partition twrp could no longer mount the partition to format it, but if you use command land format it formats the partition without mounting it.)
i'm assuming this is your issue as well.

Hi, thanks for the advice, I gave it a try last night. My /data partition was named /dev/block/mmcblk0p43 according to DiskInfo, so I made sure the partition was unmounted in TWRP and formatted it via the terminal following your instructions and then reflashed the MM zip from the original link and... still encrypted.
I haven't tried flashing the kdz yet, as I use Linux and I don't believe there is a way to flash kdz files using *nix. I'll have to wait until the weekend and I'll try and do it via a VM.
I don't understand how this encrypted partition is still even there. I have CM12 installed and working, it's showing the full amount of disk space available, I've done multiple wipes, formats and resets, yet the minute I put MM on it, the phone thinks it's encrypted again.
I do actually know the encryption key, is there any way I can unlock the phone via ADB or something similar?
Not sure if it's relevant, but my phone model is D855. I don't think I mentioned that before.
Thanks for the help, I really appreciate it!

very strange when i did that it got rid of my encrypted partition... i'm not sure what else to say except maybe see if someone will lend you a windows pc to do kdz flash.

I flashed the kdz via LGUP and... now the phone won't boot to anything except TWRP. Have tried restoring two previous nandroid backups, installing CM12 and MM, all install without reporting errors. LGUP detects it as an unknown device, so can't flash kdz again. Might have bricked this one. :crying:
Phew. Okay, solved! I followed the following guide to flash an old version of the stock firmware: http://www.androidrootz.com/2014/07/how-to-unroot-lg-g3-all-variants.html.
Then, I upgraded, rooted, flash TWRP and finally installed MM again and it seems to be back to normal ("Android is starting" screen as we speak. Fingers crossed!). Thanks to everyone who helped me out with this one!

I'm currently running my OP3 on Resurrection Remix 5.7.4 (MM 6.01), the phone has the latest version of TWRP and I've flashed other ROMs in the past without any issue
RR has proven to be quite unstable for me, the system UI keeps crashing, which renders the phone unusable until after a reboot so I wanted to flash Freedom OS as that worked quite well for me previously. When I tried to flash the ROM in TWRP the ROM seemed to flash successfully but when I rebooted, only the boot logo showed and then the screen went black and the phone refused to respond at all for about two hours, after that exactly the same thing happened. I managed to boot into recovery and tried flashing a different ROM but the result was the same every time, the only way to get the phone to work normally was to flash RR again/restore from a Nandroid backup, either way, the result is the same, I'm stuck on an unstable ROM and I don't know why, the last time I flashed these ROMs they worked fine, I followed all of the instructions for flashing said ROMs to the letter, I have the latest version of TWRP, etc.
Also it seems TWRP can't mount /system, in TWRP under "mount", system is unchecked, I checked it and tried again but found that whenever I rebooted the phone or attempted to flash a new ROM, it would always uncheck itself and flashing the ROM would fail, however strangely flashing the same version of RR was always successful. Is this why the flashing keeps failing and does anyone know what the problem could be?
Thanks!

Go into your bootloader and format system, cache, and userdata (This will wipe EVERYTHING so be sure to backup). Then latest official flash stock rom and reboot. This should fix it. If this helped hit thanks!

Bootloader? There is no option in the bootloader to delete everything as far as I can see, do you mean in recovery? And if I wipe everything off the phone, how do I get the stock ROM onto the phone to flash it? When you say wipe userdata do you mean wipe internal storage or am I misunderstanding and you're telling me to wipe the usual dalvik, cache and data as you would for a normal clean flash?
bronderb said:
No, go into fastboot and plug into pc. Open cmd and type "fastboot format userdata" "fastboot format cache" "fastboot format system"

Okay, thanks, and then what? Do I flash TWRP then push the stock ROM to the phone and flash that? And exactly how do I do that?

You just go into twrp (no need to reflash) then adb sideload oxygen os
Click to expand...
Click to collapse
Thank you, I am now running OOS, hopefully everything else will go smoothly now, planning to go back to FOS again
I didn't even have to use the fastboot commands to format, just sideloading the OOS file wiped everything anyway
Turns out the issue isn't actually fixed, "system" still appears unchecked in TWRP. Could the fact that I didn't actually format everything first have made a difference, given everything was wiped in the process anyway?
Looks like I'm going to be living the sideloading life...
Edit: Sideloading freedom OS failed, ended up having to restore from my TWRP backup. I don't know what I'm going to do, my main reason for using custom ROMs is installing a black theme, and OOS doesn't support Layers or Substratum fully so I can't stay on that
Is the thing that says "mount system as read-only" enabled in the mounts menu? /System isn't ever mounted when TWRP starts, you have to manually mount it, but as long as the updater-script tells /system to mount, it will. However, if that option to make it read-only is enabled, then nothing will ever write to /system. Last resort is deleting the .twrps file from /sdcard/TWRP folder to remove current TWRP preferences and then when you boot into TWRP, that first screen has the swiper to allow modifications, and you'll swipe that

It isn't set to read only, I have tried updating and resetting TWRP but nothing has helped, in fact it's got worse, I managed to sideload OOS but my attempted install of FOS failed so I tried to restore from a backup and that also failed, something which didn't happen back when I was on RR.

Which version of TWRP are you running? The official 3.1.0-0 is good for OOS and OOS based ROMs only. Try eng.stk's version.
Use the latest eng-stk twrp.
https://forum.xda-developers.com/devdb/project/?id=15934#downloads
In recovery go to Wipe > Format data (this will wipe ALL in youre phone).
It's youre Data in F2FS? If yes you must change it to ext4, in recovery Wipe > Change file system. Reboot recovery. Check if it's changed.
Reboot to Bootloader (Fastboot). From PC reflash recovery.
Now copy Oos rom to the phone memory. Flash rom. Reflash recovery (the rom will overwrite the recovery). Reboot to recovery to see if it works. If not do it again.
I sugest to NOT restore old data. This way you'll have all new in youre phone.

Help! I attempted to do this and the process failed, I didn't manage to wipe data because "/data could not be mounted as device or resource is busy"
Edit: Device now has nothing but TWRP and fastboot, no OS, no ADB, no data, no internal storage
If you can reflash twrp from PC. If not reflash recovery from twrp recovery : Instal > Image > Select Recovery (you must have TWRP.img in youre phone memory )
I managed to get hold of a few factory images and attempted to flash system.img through fastboot, resulting error was
"target reported max download size of 536,870,912 bytes" (system image is 3080 MB)
"invalid sparse file format at header magi"

I reflashed the modified TWRP successfully. The second suggestion wouldn't have worked, given my phone has no internal storage
You can't see internal storage because of the recovery does not work write.
If you have a working recovery you can do all you want.

The recovery was working at this point, the issue turned out to be the data partition, system was formatted to ext4 but I didn't realise data was in f2fs which caused the problem in the first place. I formatted to ext4 and everything worked, I was able to install paranoid android and everything worked...
...until I flashed the wrong firmware and now I've hard bricked it! I'm going to try the hard brick toolkit
Edit: After 12 hours of being an unresponsive brick, the phone suddenly booted, system doesn't work but it has recovery. Unfortunately I seem to be back to square one, if I try to flash something it appears to succeed but then the phone doesn't boot up into system
So I am now back to the original issue of system not mounting, in terminal if I type "mount /system" I get following error:
"mounting /dev/block/sde20 on /system failed: Device or resource is busy"
Anyone know how to solve this?
I formatted everything, reflashed recovery and tried to flash OOS, got following error:
Code:
[FONT="Courier New"]"This package is for OnePlus3 devices, this is a oneplus3t" (it isn't)
"Updater process ended with ERROR: 7
Error installing zip file /sdcard/OOS3.2.6.zip" [/FONT]
Issue was "solved" by flashing PA, GApps and the correct firmware
Hopefully that's the end of all this drama, thanks to everyone for their suggestions
Hi, I'm pretty new at rooting and I seem to have a similar error. I'm getting the "can't mount /system" error in TWRP. I am able to boot into OOS 4.1.3 and run the nandroid backup but, I keep getting the same error and am unable to select "system" when choosing the mount option in TWRP.
Do I need to have all partitions in f2fs? My system partition is in ext4. Is this what solved your issue?
It seems my phone is functional even with the error active but, I've been trying to get systemless SuperSU and MagiskHide working and I think that's what is preventing me from doing so.
Hello,
Whenever i encrypt my phone on DU, when i set the lock screen Password it asks me if i want the phone to ask it to be able to boot, but then, the phone refuses to boot and says that the Password is wrong.
But when i boot into twrp the Password works and i can decrypt the data partition.
I already had the issue but with the phone accepting the boot pin but twrp not.
This is on a fresh DU install with previously formated data partition.
DO NOT encrypt via custom roms: it's cause of troubles and compatibility issues, especially when returning to OxygenOS.
So:
1) Put device in bootloader mode, plug it to computer, type fastboot format userdata via ADB terminal.
2) Go in TWRP and wipe all the partitions (be sure to have /cache formatted in ext4, otherwise change its filesystem):
3) Always from TWRP, flash latest OOS firmware (4.1.6 or OB19);
3) Reboot and configure setup with your PIN required at bootup;
4) After completing wizard, reboot in TWRP;
5) Now you can wipe anything and flash your rom.
Now device should require your PIN even at first boot of DU.
Ps until doing another fastboot format userdata, device will keep encryption.

Come on, do not vent on XDA, do not make useless quarrels ?
@nikexv2 sorry, but technically speaking, I don't know the reason of problematic encryption on custom roms.
Just enable encryption with official firmware and there's no other compatibility issue.
Encryption still remains when you full wipe device via recovery.
Have a good day.

Not sure what's wrong with your set up but I came from OOS OB19 to DU, wiped userdata to switch data to ext4, flashed DU + beans gapps (recommended for DU) then booted up, encrypted my phone via Settings > Security and set ask pin on booting device, same pin has worked on all ROMs, even tried some OOS based ones like Freedom OS CE, now on Omni + open gapps, I'm using blu spark latest recovery.
Hello
After rooting my G3, I installed an AOSP-based custom rom via TWRP. Then later on, encrypted the phone (& sdcard).
Recently, decided to install a LG stock-based rom (Clean Rom 2.8), but can't get passed a white screen asking for a password at first boot. This appears to be something to do with encryption? (From what I recall, there's no password to set when encrypting the phone). I factory-wiped, and wiped via advanced options of TWRP before installing this rom, so thought the phone has been decrypted.
After reading around, I tried flashing the latest LineageOS rom, and it worked fine. Notably, the phone indicates it's still encrypted! though the sdcard isn't as I can access it outside of the phone. I read about this problem with some ROMs not being able to boot past a password/white screen, but CM/LineageOS not having this issue.
Anyhow, how do I fully decrypt the LG phone? I've read various advice, but confused (especially about bootloaders).
Any help appreciated.
I dont own the device right now (in the future i wil) but i think i can help u whit that.... (it happened me with other phones)
The thing is if you have encription in the phone the only way to dencrypt the device is format the data partition through twrp THIS WILL ERASE ALL OF YOUR FILES LIKE PHOTOS AND MUSIC PLEASE DO A BACKUP BEFORE TRYING THIS
Boot to twrp, press the wipe button, in the wipe screen you will see a button that say "Format data" (in the top corner above the switch saying "swipe to factory reset") then twrp ask you to type yes, you do it and this will format the data partition erasing the files and the encription....
For the sd is the same but you can do it from a computer if you want or other way
I hope that this can help u

Hello. Need help is exactly what I need right now. Basically, I just tried flashing Oxygen OS from LineageOS, as I was just getting a little annoyed about how the updates were getting stupid and apps kept crashing. However, when I did this, it got stuck on just a sec when I was setting up. I then tore through the internet looking for how to wipe /data and /data/media with twrp command line. I found out about fastboot erase userdata. I used that. However, it wasn't just the casual wiping of the data where everything goes except the critical files. I mean every single little god damn thing got removed. I tried pulling /data and it said 0 files pulled. I was not happy. I managed to flash the rom but the phone won't boot. the worst part, I tried mounting /data on twrp and it said failed to mount data, invalid argument. So that was that. I then formatted to the original using the twrp format, (needed sighted help for that...) And it succeeded. Now however, I try mounting and it says no such device. 1, how can I mount data? And 2, how can I get a data partition that actually works with setting up and even the booting up of my phone. Yes, it won't boot.
Please help me, you don't believe how annoying it is to have a virtually useless phone.
tobias
PS, I was using stock bootloader and twrp recovery. Also, please give the answer of fixing in a command line method, I'm blind so getting sighted help would be rather annoying.

Not being rude, but do you really think no verity is going to help? I mean it usually doesn't fix stuff. Besides, thanks but it's not that it is encrypted, I can flash things if I know their directery, it's just that data can't be mounted. But thanks, I'll try flashing no verity and see what happens.
Many thanks

Hello! I'm very new to building custom recoveries, and haven't even completed a successful build yet. I have a OnePlus 7T model HD1905 (aka North American model/Global) running OOS 12. I've tried to find guides on how to make a TWRP recovery, but nothing has worked for OOS 12. I am able to extract the OOS 12 stock recovery.img with Payload Dumper, and am able to create a basic TWRP device tree for android 12.1 using the official TWRP 12.1 Github manifest, but I'm not able to find a good guide to create a TWRP-ready device tree from my stock recovery.img I mentioned earlier. I've tried updating to OOS 11, and using the twrp-keep module on the magisk modules github to keep the official TWRP installed. (It support OOS 11, but not OOS 12). I've also tried flashing the unofficial build made by Mauronofrio, but none of the specified methods have worked. Can someone please either make a OOS12-compatible version of TWRP for the OnePlus 7T, or if they can't do that, guide me in a step-by-step process on how to do i myself? Any help would be greatly appreciated.
Oos12 does NOT support twrp nor does A13
I compiled it but i didn't test it with oos12 (fbe) and custom rom a13 (erofs). I hope it will work..

I just flashed it, and it booted successfully! I'll let you know if I can format /data.
Format /data works.
For confirmation, I flashed the .img of the OOS12 version to the recovery partition.

So... upon further inspection, there's an issue with decryption. I can successfully flash the image to the recovery partition, and it boots just fine. When I tap on "Mount", all of the options are unchecked. One of the buttons is called "Decrypt Data". I currently don't have face unlock, fingerprint unlock, password or PIN set up, and it still promts me for a password when I tap on "Decrypt Data". I've tried entering "default_password" and "password" (but without the quotation marks), but neither of them work. Is there a way to solve this? This is on the OOS12 TWRP, btw.

I just tested the non-OOS Android 13 TWRP file, and it has the same issue.
Can u back up all partitions except data? At least that would be helpful

Nope. Even when I de-select Data, and select everything else, it still fails with the "Failed to mount /data" error.
Yeah, I was afraid of that. No one has cracked twrp for oos12 yet

I mean, at least both of them boot.

Hi again. As I've mentioned, both TWRP images boot just fine. However, I am unable to mount /data, as when I enter the "Mount" section of TWRP, nothing except the Cache partition is checked. It doesn't ask me for a password upon booting into TWRP, however it DOES ask for one when I tap on the "Decrypt Data" button in the "Mount" section. I've tried entering "default_password" (without the quotation marks), "password" (again, without the quotation marks), and also my password that I set up when I flashed LineageOS 20. I'm curently running LineageOS 20 on the device. I'm able to access USB OTG in TWRP, but I'm not able to flash anything from there. I'm also unable to change boot slots, or backup any partitions. Formatting Data doesn't allow me to access the data partition on rebooting, and the only fix I've been able to find is changing the data partition format from ext4, to ext2, and then back to ext4. This only works temporarily, and only with OxygenOS installed. Even then, after I change the data partition's format like I mentioned above, it resets my data, as is expected. After setting up the device again, and rebooting into TWRP, the /data partition goes back to being un-selected, and I have to repeat the process over again, and once again lose my data. I am unable to carry out the process described while running LineageOS, and its respective TWRP file that you have made. Any help would be greatly appreciated, and if you know the password that TWRP is asking for in the Mount section (when I select "Decrypt Data"), I'd like to know what it is so that I can hopefully get the rest of TWRP to work. Even with these issues, I'd like to give MASSIVE thanks to you, because you were able to do something that my inexperienced self was able to: That is, create a TWRP file that boots, made from the latest custom rom files, and the latest OxygenOS versions' files.

Thank you for testing the builds and for the feedback . I've been on oos11 for a long time, but today I'm going to flash oos12. Because i would need recovery log files to fix errors.
I don't have no time for some fixes, i will try to fix errors whenever possible.
did you not ttry to use the twrp and the twrp installer builds that are on official twrp site for one plus 7t
then how are folks then flashing roms to one plus 7 t devices if there is or isnt a working twrp .

Every ROM comes built-in with its own recovery. So you'll have to flash the ROM via that recovery's ADB Sideload feature.
lets hope you can get a working twrp going for both andrid 12 and 13 .as my one plus 7t is just been put away in my drawer after seeing that one plus has given up on these older devices. when there is a working twrp i would probably want to flash something down the road. my primary driver unfortunately is a samsung S21 plus .

All works until I tried to restore. Then it got stuck at red dot going around in circle. When I tried to go back in twrp again to format data, it won't mount data after that. Ended up having to restore all over using msmtool.
It mounted data fine before I tried to restore the data part, then it messed up decryption of data despite not having a lock code, no fingerprint, no pattern-lock, or lock screen enabled.
