Hello everybody,
I think only an expert can help me !
LG G3 is ater few minute to fastboot mode.
1- no download mode, only fastboot.
2- the system, data, cache is in read only, cannot remount with rw permission, get error messege:
Invalid argument and E: Unable to mount '/system , '/cache , '/data and storage.
cannot flash via fastboot or adb.
when I run:
1- dmesg | grep mmc0 i get i/o error about logical block 0,1,2 and 3, buffer i/o error.
2- fsck_msdos dmesg I get i/o error.
some how it can install via srk tool 2.1 twrp recovery and I try to repair the system or format or change partitin type with twrp.
Hi,
Nice to be here after so much years of reading !
My LG G3s (d722) was fine with Cyanogenmod 13 and encryption enabled. I've made a Titanium backup for my apps (& cie...) on the SD card, and reboot in TWRP 3.0.2-0, enter my password to mount storage, and I've wiped all partitions exept the SD card.
Then I've flashed the CM14 zip file, and get these error in the process :
"could not detect filesystem for /dev/block/platform/msm_sdcc.1/by-name/userdata, assuming ext4 mount: failed to mount /dev/block/platform/msm_sdcc.1/by-name/userdata at /data: Unkown error 200 unmount of /data failed; no such volume"
"Failed to mount '/data' (No such device)"
Since then :
- if I reboot into recovery, TWRP doesn't ask me the password to decryp the partition
- if I reboot in CyanogenMod ask me the password, but the tells me :
Decryption unsuccessful
The password you entered is correct but unfortunately your data is corrupt.
To resume using your phone, you need to perform a factory reset. When you set up your phone after the reset, you'll have an opportunity to restore any data that was backed up to your Google Account.Then it reboot into TWRP
Any ideas ?
How could I mount ext4 partition in TWRP ? Or restore stock recovery ?
Thanks a lot for your advices
resolving !
Hi myself and everyone from another time,
I've resolved this mess by :
- installing LG drivers
- downloading kitkat stock-rom D72210d_00.kdz
- open LG Flash Tool 2014 and load D72210d_00.kdz, and start a CSE Flash
Then stard android 4, root it... etc
Best
TWRP won't start after updating from 3.3.. to 3.4.0-0 using fastboot. Output includes "Failed to mount '/data'" - see following post.
I guess because I accidentally ran fastboot unlock although it was already unlocked. (The TWRP website fastboot update procedure starts right back with installing the tools and I jumped in at the wrong place)
Tried installing previous TWRP version but no dice.
Any ideas?
I did a TWRP backup before all this. Not exactly sure where it's located but would like to recover it if possible. Will a factory reset likely overwrite it?
Lenovo P2 LineageOS 17.1 Kuntao

Renamed stock recovery file in /system to prevent the stock ROM from replacing TWRP.
I bought a used OnePlus 7T Pro (256GB). I followed these instructions: https://wiki.lineageos.org/devices/hotdog/install
Unlocking the bootloader worked without problems. To install a recovery, I had to replace "recovery" in the command with "boot_b", but then it worked fine. The copy partitions script also seems to have succeeded. But then I can't install LineageOS and many other recovery features do not work, either, both in the LineageOS recovery and in TWRP.
When I start TWRP (and set my usual vibration, brightness etc. settings), I get the log output from the attached image. I wanted to copy it, but writing the log to /data/media fails because of this issue, too, so here it is hand-transcribed, hopefully correctly:
Failed to mount '/system_root' (Block device required)
Failed to mount '/vendor' (Block device required)

Many things I try in both recoveries fail with similar mounting errors. I tried everything wipe related, but none of it helped, most didn't even work. I also cannot install LineageOS from TWRP (instead of ADB sideload), because no files are listed on the internal SD card, likely because of this mounting issue.
How can I fix this? Since the phone is new anyway, I would be willing to reset anything.

It seems to me that you have to flash the super partition, try first using TWRP and if it can't deal with then try through fast boot.

I have never heard of a "super partition". How do I do that?

Sometimes can be an error from TWRP itself, an older version that can't manage to mount those partitions, but sometimes it happens that the super partition is corrupted, you could find it from your stock ROM and then extracted and flash it either through TWRP or using fastboot.

Do you have a link to a tutorial or so for that?
BTW, the preinstalled operating system boots just fine, so I would be surprised if any partitions were corrupted. I'm also using the latest version of TWRP, at least it's the one that I got on their website yesterday.

Super partition is where some logical partitions are grouped like system, vendor, odm, product, etc.; it depends on the device we're talking about.
As you got a used device, it seems that the last owner did some stuff with it, probably unlocked bootloader (then relocked it) and mess with some custom ROMs (maybe). You can totally fix it by flashing the stock ROM and starting from there, being sure first that you can log in without issues in Google Play (that your account is authorized).
To have this partition readable, you may read this https://forum.xda-developers.com/t/...-mount-system-rw-super-rw-read-write.4247311/ in case this doesn't solve flashing the super partition it is a part of the process to flash the stock ROM.

You mean it's in some script in that zip file? Because what I found online just tells me to do the same "adb sideload" with the OxygenOS zip. And that doesn't work because of the same access issue. Or is there something else I should do first?
The link you gave says that it requires a rooted ROM, which I don't have yet.

You can update through the stock recovery in case your TWRP have actually some issues, flash the stock recovery through fastboot (get it from your stock ROM) and then do the sideload through stock recovery, it's probable that the stock recovery can mount super partition and made readable again the system files that´s within, or you can simply flash this or that partition using fastboot commands, for this you need an unlocked bootloader, nothing more.
BTW did you try formatting data?.
And this tool should work for you https://forum.xda-developers.com/t/...l-to-restore-your-device-to-oxygenos.4217855/
That tool says it only works for Windows. I have gotten rid of my last Windows system last year.
Not sure what you mean with getting the stock recovery from the stock ROM, since the zip only contains "payload.bin" (extension suggests binary file, no idea how to read that one), a small txt file and a small "META-INF", but here is a download at least: https://forum.xda-developers.com/t/oos-all-stock-boot-stock-recovery-oxygenos-11-0-0.4251221
There's even a Magisk version, which I'll try first, since I want that anyway. But for now, I'll sleep. I'll comment again once I've tried it.
BTW, can I stop this website from jumping to the category overview after a few seconds, while I'm trying to just read a post? It's really annoying.

The ROM to be flashed through recovery contains a payload.bin file within others one, this file can be unpacked, not sure if it contains a recovery image though, but you should get it from the full ROM that in some variant comes in oplus format and can be decrypted too, this full ROM contains all the images, it's useful to unbrick a OP device.
Linux doesn't have a counterpart of the Windows applications for smartphones and vice versa in regard to Android development, this is one of the reasons why I have a dual boot machine.
As per the last part it could be an issue from your browser, I didn't have this kind of behaviors from the XDA site.
For "boot.img" and "recovery.img" in the "EU" and the "global" section I get "fastboot: error: boot partition is smaller than boot image". The Magisk version can be installed, but then I get a Qualcomm crash screen when I try to actually start it.
Apparently I have a "OnePlus 7 Pro", not a "OnePlus 7T Pro". I bought that accidentally, but the specs are fine. Actually following the instructions for the correct device worked, who would have thought…
