[Q] Problem with system partition - Nexus 7 (2013) Q&A

Hi, i have several problem or maeby is the same. I'm trying to go back so stock system and i can't i already reflash al *.img except system i always have errors: "FAILED (data transfer failure (Unknown error))" and only with system, i already install twrp and pass with adb push the system.img to the tablet, but twrp doesn't allow me to flash to system partition.
So i have some doubts:
1) is there a way to know if the memory is damage in some way?, i mean physicaly damage.
2) can i flash system partition from the device? twrp or any other ways?

[Q] GPE 5.0.1 Bricked my phone - can anybody help?

Hello everyone
So I have a m8 and converted it to the GPE edition. I changed my CID & MID and installed 4.4.4. My phone was rooted and I installed custom recoveries and went back to the stock recovery.. Here is what went wrong.
Today the update 5.0.1 came, when I tried to install it the update was failing and said my Version is not the right one. So I found out, that I flashed an old recovery and because of that it could not install it. Ok, downloaded the original OTA of 4.4.4 extracted the recovery.img and flashed that one. Now the verification check went trough..
It startet installing and after 5 minutes the update failed! Saying something like, it could not create symlinks on the system... I tried again, and now it stops with this error:
fileexist(): check the existence of /system/lib/libgoogle_recognizer_jni_1.so failed, error no such file or directory() installation aborted...
My system partition is broken now and i cannot start any system anymore...
I would like to save my data or install anything that my phone is working again, but I want to keep my data.. My phone is encrypted! :/ I tried with custom recoveries, but they apparently don't support disk encryption on the m8...
I think I cannot flash 4.4.4 with RUU as this would also delete the data... adb backup only works if the system is up, because the shell command tells me that a system dialog will appear and ask me for my password....
Anybody has any suggestion how to save my data?
Thanks!
should be in Q&A mate
I have requiested the mods to move this
So first things first. You are not bricked, you are just stuck. Bricked means your device cannot boot, cannot turn on, cannot access any bootloaders or recovery.
You messed something up and it is failing to boot, it isnt bricked.
Second, running disk encryption on rooted devices is especially dangerous for these scenarios. Disk encryption attempts to prevent many of the things running roms, custom recoveries and such put on the device.
Now, I cannot recall if a full GPE version can do this or not, but from Fastboot you should be able to flash just the system partition. But being you are encrypted it may fail to access your old data. The command for that would be:
Fastboot flash system system.img (if you were able to obtain a system.img)
Again that works on Nexus devices, I cant recall if the GPE fastboot accepts it as well.
Wish you well, but honestly I would expect to lose your data. The reason the update failed the second time was because you are Rooted. 5.0+ has a new OTA system where any changes to the system partition can/will fail the OTA.

First, your phone isnt bricked, its not bricked as long as you can access HBOOT, second, why would you encrypt your phone? uhg... I dont know what to tell you, try RUUing to stock, but dont expect to keep your data...
I also had the idea with just flashing the system.img from fastboot. but that doesn't work..
target reported max download size of 1830617088 bytes
erasing 'system'...
FAILED (remote: not allowed)
finished. total time: 0.010s
i now try to flash it with dd directly to the block..

You can only flash boot and recovery individually, you would have to put system.img and android-info.txt in a zip and flash in ruu mode
UNBELIEVABLE!
I could restore the system with dd... Just copied the system.img from Android 4.4.4 to the block device.. now the phone is booting up and i can see my data... uffff.. :victory:
so now i will do a backup and then go on...
Solution
If someone should encounter the same issue, this is what I have done to fix it:
I didn't want to lose my data, so I did not reinstall the RUU.. I couldn't get my data with ADB backup, because you need a system display to do it. And I also couldn't find any recovery which supported device encryption for the m8.. So I thought to backup my data partition with 'dd' to an external SD card and then if necessary I would reinstall the full system with RUU..
Code:
$ cat /fstab.qcom #to find the needed partitions
$ dd if=</dev/block/DATA-DEVICE> of=/external-sd/backup.bin
Now I knew I had a backup and was on the safe side. So I wanted to try to rewrite the system partition with the system.img from 4.4.4 GPE RUU. But fastboot flash didn't work. I always got this error message:
Code:
$ fastboot flash system system.img
...
erasing 'system'...
FAILED (remote: not allowed)
finished. total time: 0.010s
So what the hell, I used 'dd' also for this... :
Code:
$ cat /fstab.qcom #again to find the needed partitions
$ dd if=/external-sd/system.img of=</dev/block/SYSTEM-DEVICE>
And this actually worked, my m8 booted up with Android 4.4.4. First thing I did when Android booted was a full Android backup with adb.. To be safe to have my data back, because I didn't really know how to extract my encrypted data from the bin file I've created before... Then I just installed the update to 5.0.1 and this time it worked...

Stuck after trying to upgrade to Pie.. worried I bricked it.

Having an issue with my XL. I've been on LOS 15.1 for a while and wanted to try out the new Pie image. I made a backup and fired up fastboot as usual. I left the -w tag on as I wanted a complete wipe. Fastboot failed while wiping userdata and now bootloops twice before dumping me in stock recovery. I am completely unable to format data while in stock recovery. Same when I boot TWRP through the PC. Stock recovery says it can't write a new EXT4 partition and TWRP says I have no internal storage, then throws a ton of errors. Flashing OEM images from Google (Oreo or Pie) results in the same thing.
Any ideas? For the first time in years I am stumped.
I'm able to flash just about anything with fastboot, but it will always fail on writing to userdata. I'm unable to erase, format, or mount the userdata partition, and fastboot will always reply "FAILED (remote: flash write failure)". This is using the most recent platform-tools under a root shell in Linux. Device and bootloader are unlocked.
I recently tried the original factory firmware (which includes a userdata.img fastboot file) to no avail. The same "FAILED (remote: flash write failure)" error persists.

Is your platform tools updated to the newest one?.
Edit I thought I was on the pixel 2 forum.
Could try to repartition the storage using a method similar to this one for the nexus 7? https://forum.xda-developers.com/nexus-7-2013/general/guide-repartition-nexus72013-to-t3599907
You would need to figure out the proper partition table for the Pixel though.
If you're 100% sure your platform-tools are fresh, you've got me stumped as well. I ran into tons of errors and such due to out of date tools when flashing Pie - obviously updating the tools fixed the issue.
Well I'd try external Type-C USB drive it enables external storage even if internal isn't working and fastboot flash your backup.

i got the same problem, i just downloaded the Platform-Tools and opened it in PowerShell and executed flash-all script and it worked
Flash all script is good but I'd rather use external storage .. it's nice to know that there's more than one way to fix the problem outside of platform tools
I had issues with Pixel before and the multi partition thing screwed me up, but the Unified_Android_ToolKit was able to fix it for me. Worth a try for sure. Download Google Factory Image and use the tool.
Thanks for all the help everyone. Lots of good ideas here that I'll save for next time. Ten years tinkering with phones and I've never gotten this stuck.
In the end I flashed back to the factory Pixel XL image (October 2016). Like the previous attempts, it failed on accessing userdata. I used fastboot to flash a userdata.img file again, which similarly failed but somehow the phone still booted after about 20 minutes.
I found similar threads for other phones where people were in the same situation, but nothing they tried did the trick.
Back up and running now.

Very odd. Based off your last post I'm going to assume you are not sure what triggered the issue?

How to flash a treble img without fastboot (/system wiped, twrp operational)?

I may be in a tricky spot here. I've a Palm phone which doesn't have fastboot. I flashed twrp and a replacement system image but the system image didn't boot as planned. I wiped it with the intention of replacing using dd which writes the data, but the partition is corrupt and can't be mounted.
How to recover? TWRP only has 'boot' and 'recovery' as options for the img flash, which I assume is because it's using fastboot and that isn't available.

Try manually formatting the system partition into whatever your device has as default, ext4 for example, or alternatively reinstall the stock Rom and continue from there, also, wrong thread

New MIUI Update does not update (reboots into TWRP)

Hi guys,
I have a rooted mi10t lite on MIUI.
Got an update today (miu v12.0.2.0.RJSEUXM) so downloaded it via phone and pressed 'reboot now'.
Issue is the phone reboots into TWRP recovery and when I boot back to system the phone still tells me to update the phone by rebooting it which goes back to TWRP.
I tried to install the update via TWRP > Install>
The internal storage is encrypted though so I moved the updated .zip file to my SD Card (root of SD card folder).
I go back into TWRP after a reboot and flash the install but get an error when trying to install the update. Not sure why?
Code:
E: Unble to decrypt FBE device
Updating partition details...
...done
Updating partition details...
...done
MTP Enabled
Installing zip file '/external_sd/miuupdatenumberetc.zip'
Checking for Digest file...
Error installing zip file ''/external_sd/miuupdatenumberetc.zip'
Updating partiion details...
...done
Any ideas please? I don't really want to update the phone if it results in me losing everything and having to install magisk and TWRP again, etc.
Thanks
1. to install OTA update from system, you have to have stock recovery
2. installed TWRP can not decrypt data partition
I would:
1. restore stock recovery
2. install OTA update
3. hotboot TWRP so you can decrypt data partition (fastboot boot twrp.img), install Magisk
Your Magisk modules and all data will remain intact.
i have the same problem. if i want to restore stock recovery, is it the right way to flash via fastboot the recovery.img from the fastboot rom, or i will get issues?

Question [URGENT] TWRP fails to decrypt /data partition using the correct passcode and can't mount /cust partition with error "Structure needs cleaning"

Long story short, read the previous thread: https://forum.xda-developers.com/t/...-product-vendor-odm-invalid-argument.4431903/
After succesfully installing the fastboot rom via Mi Flash, the phone is still in a bootloop. Tried flashing TWRP via fastboot command (fastboot boot twrp.img) but it can't decrypt the /data partition with the correct passcode anymore. after a reboot in recovery, the /cust partition also can't be mounted anymore, with error "Structure needs cleaning".
I do not have a backup of my system nor data partition, nor internal storage, so i absolutely need it to work again without wiping/formatting the data partition
EDIT: after flashing the fastboot rom again via mi flash and twrp via fastboot command, the cust error disappears but twrp still can't decrypt /data
EDIT: i decided to do a full wipe of my internal memory and the phone works again. this thread should be closed.
