Hi. I've just updated CM13 to the latest nightly using TWRP, but now the system just boots into TWRP - that's whether I select boot system, recovery, or bootloader. I tried restoring from a TWRP backup or another copy of the nightlies zip - it all seems to work fine but doesn't solve the problem. I can connect to the 'recovery' device using adb but adb restart bootloader just loads TWRP again. I've tried wiping first the dalvik/cache, then everything but the internal card, then finally everything but nothing seems to work.
I did get something a little bit like this a few days ago because SuperSU was complaining that I needed to update the binary. I let it do it the way that it suggested one does when TWRP is installed and afterwards couldn't reboot into system, but after a few minutes of frustration sorted things by wiping various partitions.
I attempted to load the full system restore files (cm-13.1-ZNH2KAS29G-crackling-signed-fastboot-74bb753396.zip) using TWRP but that didn't work (I imagine because they're designed to be run via fastboot). I tried loading them via the ADB sideloader option included in TWRP but it failed after a few seconds (I think the message was 'transmitting 0.0x'
I opened that zip and copied the various files to the external card, but I then baulked at installing the image files manually because the only partition option I'm given is boot and my understanding is that each image file should go into its own partition.
The only other potentially pertinent information I can think of:
TWRP keeps reporting "E: Unable to find partition size for '/recovery'"
Has anyone got any ideas please? I had been musing that my next phone would have OTG and NFC, but I wasn't planning to upgrade just yet if I don't absolutely have to.
Have you got it fixed? And if yes - how? I am stuck in a similar situation and can't find a solution for it. Tnx in advance.
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

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.

I was running 3.0.2-2 when the issue started, I updated to 3.0.3 and 3.1.0-0 but nothing changed. Thanks for the suggestion, I will give it a try

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.
Hi there, so I'm having a bit of a problem. I tried to revive my old M9. I remember flashing it with a custom ROM (Android HD Revolution) and everything was fine. I left it since I got a new phone and today wanted to play around with my M9 again.
However, it would be stuck with the HTC Logo while loading, and my TWRP was gone, could no longer boot into it and my download mode was also screwed, as it gave me the error (failed to boot to download mode).
Anyway so I tried restoring to one of my TWRP backups, by mounting a TWRP img file first using my PC. It went fine, after that I booted into system and the HTC logo would be on white background and preventing me from using the screen, although funnily enough the system was functionally normally i.e. the volume keys worked and I could see it change on screen but, it was just as if I had a some kind of overlay and couldn't use the screen itself by touching.
I then tried to flash with the same custom ROM, but after installing it and rebooting the phone it was stuck in a boot loop, where it would shutdown and try to boot again.
So I turned it off using power up and home button, and tried to wipe the partition to install another ROM, using the same TWRP method I did above.
Only this time, I can't do anything: wipe, install, format etc. I get the error "Failed to mount '/data' (Invalid Argument)" "Failed to mount '/cache' (Invalid Argument)" whenever I try doing anything within TWRP. I can't even mount cache, system or Data. It is if they're not there.
And now my phone is back to where it started, i.e. infinite boot screen with HTC Logo and "This build is for etc..." text.
Note: Trying to change file system from ext4 to ext2/3 and back to ext4 does not fix the problem ,as the same errors pop up when trying to change file system.
90% chance the nand is goosed. 10% chance of recovering by flashing a stock firmware in download mode (same version as currently installed, external sd card method).
Twrp has a known issue for bricking devices at random.
Hi,
I'm using a Poco F3 with latest stable Xiaomi.eu 12.5.3.0. With older phones, I could avoid having a pattern/password while still using the finger print sensor by deleting the file at "data/system/locksettings.db". Since it is something I have done many times with other Android phones, I didn't expect it could be a problem, but after deleting the file, the data folder is encrypted and I have no way to decrypt it.
After deleting the file and booting into MIUI as usual, all my apps says "wait until your device is fully rebooted before opening apps". I can open system apps like the clock or the weather, but that's it.
Things I've tried:
Factory reset from the device settings. After pressing the button, the screen gets black and after 2 seconds it gets back on the settings menu.
Change the security settings. Both changing the pattern, the password or leaving it without security. It only affects how the device is locked, but nothing else.
Using adb, I have no permission to see the data folder and the sdcard folder says it does not exists.
From TWRP, if I had set any kind of lock while in Android, it will ask for it (such a pattern or password). But whatever I input, it always says "Failed to decrypt user 0". I can cancel the input and enter normal TWRP but with the data folder encrypted.
I've tried to Wipe>Format Data, with the following error message:
Code:
/system/bin/make_f2fs -d1 -f -0 encrypt -0 quota -0 verity -w 4096 /dev/block/sda35 27865079 process ended with ERROR: 255
Unable to wipe Data.
Unable to format to remove encryption.
Updating partition details...
Filed to mount '/data' (Device or resource busy)
In Wipe>Advanced Wipe>Repair or Change File System (to the Data partition). If I try to repair it gives me error 255 again. If I try to Change File System to F2FS, again "Error chaning file system".
I cannot flash Xiaomi.eu again from TWRP because I cannot move the file to the phone through adb "permission denied".
What other options do I have?
Thanks in advance for the help.
flashing stock miui theres a fastboot flash userdata that might do the trick.

U can try to flash a stock ROM using MiFlash tool and flash xiaomi.eu ROM again.
Also you can use a USB OTG to flash from twrp

I thought I couldn't downgrade to stock rom because of Anti Rollback restrictions, but it did work and solved the problem. Thanks for the help!

Didn't think of that, unfortunately flashing from TWRP does not format the data partition, so it didn't solve the problem.
