Hello,
i need help. I messed up my phone while trying to repair my only read mode system partition after boot.
Current state:
Phone CAN-L11 with EU Firmeware and working TWRP Recovery.
I did a full wipe, but have no data partition to restore, because this couldn´t be saved with twrp while i made my first nand backups during no read access to data partition.
My phone always shows 2 times the huawei logo and then boot in erecovery from huawei where i tried to restore, but it shows always "fail to get data" (wifi works).
When i restore all partitions backups that i own via twrp i miss the data partition (is the cause why it wont boot - isn´t it?)
Now i searched for any img that i can use to get my phone working again - anyone has a tip what img i could use (i have a huawei update extractor) - through twrp or fastboot.
Could anyone help me with a twrp backup or a img file of data partition - or has another tip how to get my phone working again?
Thanks for tips!

I think that you need a system.img, so you can flash. This system imagem would write everything you need, so you can boot normally.
Have you tried to dowload @bluesmoothie backup from dropbox from the Root and Recovery post?
Here is the link, in case you don't find it https://www.dropbox.com/sh/qrk0fbpn5rnukxn/AAAmhFwBTNoqq0sWfCH-VMHLa?dl=0

Here the full Backup for the CAN-L11:
https://drive.google.com/open?id=0B134drJ4-Ed0R3VSY3A5NGpjVWc
Format /data, reboot recovery and than restore from backup. After the restore is complete make a wipe.
I restored my system from twrp (original first save). But that did not help.
After that i loaded the can-L11c432 update.zip from huawei and extracted with others the system.img - that also did not help to boot.
Tomorrow i flashed the orignal recovery.img from c432 but i did not find an update.zip wich works to manually flash in stock recovery.
@Vinnom the link you shared leads to twrp.img (no system.img).
@-=MoRpH=- thanks, i will try and report back. Is this anyway a chinese version in there? I think i have the same struggle you had days back. Is your phone completely working again?

I report back later - first family dinner

Inside the folder twrp and its subfolders there it is system.img. I'm downloading it myself.

@merlin21 yes it sounds like my problem after I tried to flash the emui5 beta.
My phone is fully working again with the backup I posted.
This is not the Chinese version, if nothing works, you can try the caz ROM. But there are massive problems with the gapps, they are not included in the rom.

i just flashed the twrp.img with fastboot from xelfmade v22.12. and then rebooted twrp.
Then formated data and confirmed with yes - rebooted recovery and tried to restore your twrp. It did not restore and aborted instantly with the error message
during restoreing cust...
extractTarFork() proecess ended with ERROR: 255
what could that be?
IT WORKS! Thanks @murph... I had to use the cust from my backup, but with your data partition it successfully booted again. Locking forward if i now have still the problem with read only system partition. I am away setting up phone again (and of course rooting, modifying etc.. but FIRST do a full backup after basic setup and safe in PC !!!)
Thanks!
P.S. how did you manage to back up data partition in recovery? I thought this wouldn't be possible?! What is the cost for having this full working twrp?
PPS. Somehow knock on screen for screenshot does not work - could be, that i have to log in with huawei id... does it work for you morp?

That only work if the is not rooted... Idk whats up with that, but for now i use the quicksetting screenshot function.
Somehow it worked with my rooted device before. Must be the decrypted data partition?
With the recovery of your backup I could not access data or change memory from data to sd. What version do you use?
I flashed xelfmades v22 and now have rw access and could backup all partitions and restore. Root and xposed modules everything works, just the knock on screen to capture don't...

May I ask how?
I'm kinda stuck personnaly. I have tried both Nand backups but no cigar. Still can't boot. I had the Data issue which I managed to get rid of.
I still end up with a ExtTarFork 255 kind of error. I tried to change the files attributes via adb shell, but it failed so I've got an OS-Less phone...
Any help would be greatly appreciated.

I copied the backup, which is linked somewhere in this thread, to my sdcard and restored it on my Nova using twrp. The extractfork issue showed up while restoring '/cust' so i disselected cust in the restoring menu. After that the restoring worked and my nova was able to boot.
Hope this is any help to you.

That didn't do the trick for a while, or I might have forgotten a step, but deselecting CUST did the trick.
Thanks for the tip!
Although, maybe flashing the Cust partition I found in one of the two upgrade zips via fastboot might have helped? I dunno...
But in short, for those who haven't followed through, here's what I did, but I'm not sure this is why it worked:
1. Bricked my device : be sad;
2. DLed all the posted Nandroid backup on this thread and others;
3. With fastboot, reflashed TWRP from Xelfmade using "fastboot flash recovery twrp.img";
4. Flashed the CUST.img I found in the UPDATE.APP of the update_data_full_CAN-L11_hw_eu.zip; or maybe the other, only one of the two seem to have it; I extracted it using Huawei Firmware Extractor; using "fastboot flash cust cust.img";
5. Created a "fake" backup to create the right folder structure on my SD (TWRP Couldn't see the backups) and put the Nandroid Backups I DLed earlier in it;
6. Reboot in TWRP and Restore all partitions except CUST;
7. Reboot, sweat, wait, cry, roll on the floor in fear, heard the huawei startup sound, cried as if it was my first born child;
8. Setup the fone and profit; then enjoy Nova goodness;
92.324. and probably most important, TWRP BAAAACKUUUUP!!!!!
All done!
Thanks for your help my phone is saved with your method!!!
i downgraded my MLA-L03 variant with this, but now im stuck in french language with no other languages to choose from

Can any help, please?

Frankly, I don't know. I had not modified the partitions prior to bricking my phone, so I think the partitioning was OK. However, I think one of the TWRP availble in this forum can format Data partition properly, which would utlimately allow you to select which File Format you want. I haven't tried it myself, and I haven't been able to do much with TWRP since I flashed Lineage unfortunately. Most of my Mods were just upgrading and I had to ADB Sideload pretty much everything since I flashed Lineage...
Sorry I couldn't be more helpful than that!
first of all I'm sorry to create a new thread and it is different from other's problem.
first I'll tell what I have done.
flashed f2fs recovery by bugerXXX
formatted data, cache partitions to f2fs
flashed lineage os by harsh
rebooted to system & it was booted.
(no problem till here)
then I again rebooted to recovery
backup system& it just rebooted in the middle of the process
and that's it it never rebooting to system.
it always rebooting to splash screen infinite times when I try to power it on.
recovery works
fastboot works
download mode works
tried flashing different ROMs
reformatted data cache partitions to ext4
it always rebooting to splash screen infinite times.
even I flashed ROM (kk&lp) with QFIL and results are same.
but after flashed kk it completed boot animation and entered setup wizard, then again it started to rebooting
I think it has some problem with partitions or emmc
is there any thing that I can do to revive my phone?

Revert back your partitions to ext4
Wipe them
Fix them using fix option
Flash lollipop stock ROM
And see if it boots up
And next time be sure to ask for help before doing anything so that you don't end up like this
And contact me if it does not help
Don't forget to fix partitions
still same problem

you mean " repair file system " in twrp??
I have formatted system, data, cache to ext4
and repaired them using "repair file system" in twrp
flashed s061 stock ROM
but the problem still present.
and I wanna know what is " validated_emmc_firehouse_8916.mbn". can I use it instead of "prog_emmc_firehouse_8916.mbn" in QFIL ??

The sequence of flashing files is written in scatter file so even of you change the file and it is not meant to be flashed it won't flash
I don't think there might be a hardware fault
i am also suffering from this same problem
So I'm having a weird issue. Whenever I flash any kernel other then stock it stays stuck at the LG logo. I have to pull battery and then restore the stock kernel backup. I have no idea why I'm having this issue. I've also noticed that TWRP sometimes says cannot mount system (probably not the culprit but just adding more info).
Model: T-Mobile (h918)
When I had the "cannot mount" issue, a system partition format was needed from within TWRP. I took a backup of system (not a system.img backup), then formatted system only, then restored the system. It's been fine ever since.
I'm not sure if any special pocedure is needed for the h918 in order not to brick anything. I'm on US996.
I hope that made sense. Please wait for a second opinion before trying anything.

Yea. Seems like I have to format system all the time. Also have to format my internal storage all the time. My backups never seem to restore correctly. I can't flash a new ROM because it wont boot with a different kernel. I might just flash KDZ and root all over again.
Hi, I am trying to make a nandroid backup using twrp on my LG G6 H870, but I am unable to do so as the data fails to be mounted. I have tried to repair the partition using twrp but I just get an error 8 and I don't know what that means. If someone could help, that would be great. I am doing this so that I can safely restore to the stock rom from HavocOS.
Thanks

Hey folks. I'm hitting a brick wall trying to figure out this issue and I'm hoping someone will know how to fix this.
I have a Galaxy Tab A 8 (SM-T350) that I rooted and successfully flashed with first crDroid, then Lineage (both Android 9.0) using TWRP. I had made a backup before attempting this just in case I wanted to revert to stock.
Well, that didn't go as smoothly as I was hoping. Ever since trying to restore my backup, I've been stuck on a continuous boot loop that I can't seem to fix.
I keep getting "E:failed to mount /efs (Invalid argument)" and "dm-verity verification failed. . ." no matter what I try. I've googled the error and tried every solution suggested but I still can't get it to boot.
Any help at all would be greatly appreciated. Thanks.

Ignore the EFS error its probably a red herring. Your issue is dm-verity.
3 ways around it. Return to complete stock, including wiping the data partition or flash root (magisk suggested) or disable dmverity using one of the zips out there.

Thanks for the reply ashyx.
I've done two of the three things you suggested. I've tried returning it to stock using an image matching my exact model, and I've tried disabling dmverity. I've also tried rooting it but using a method other than magisk.
The flash seems to go well enough, but then I get stuck at the Samsung logo whenever I try rebooting into the system.
I've tried waiting, thinking I'm just being impatient, but it doesn't ever seem to get past the logo. I've tried googling ways to fix it being stuck on the logo but nothing I do seems to work. Is there any other way around it?
Side note: I've been able to flash Lineage OS again and might just have to stick with that if I can't flash it back to stock. Do you know any resources for replacing the default apps? I've tried GApps but I was wondering if there's a similar Samsung installer?

You need to wipe the data partition, aka factory reset before or after installing the stock firmware then it will take anything up to 15 mins to boot.

I did and I have been restoring it.
So far, this is what I've attempted:
Flash TWRP (twrp_3.1.0-1_sm-t350_18317.tar using Odin3 v3.10)
Reboot into recovery
Wipe everything from tablet
Format tablet
Reboot into download mode
Flash stock image with Odin
Reboot into recovery
Wipe dalvik cache
Restore backup (including efs partition)
Wipe dalvik cache (again)
Reboot
Get stuck on Samsung logo (left it for hours with no change)

Don't restore everything just EFS No need to keep wiping dalvik it serves no purpose when formatting or wiping the data partition.
Also FORMAT not wipe the data partition (note this wipes internal storage)
If it still doesn't boot install the combo firmware. Let it boot, factory reset from settings then reboot to download mode and install the stock firmware again.
