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?
So sick that my phone did not work. Now working with my "old" LG G2...
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

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!
Hello,
I have an S7Edge and looking to flash it. I am currently in Nougat 7.0 and would like to backup my data before proceeding with the root.
I have flashed the phone with TWRP but when following this tutorial: https://forum.xda-developers.com/s7...overy-official-twrp-hero2lte-3-0-0-0-t3334084
People say that you have to format the Data Partition in order to proceed with the installation of SuperSu and NO Dm verity.
Is there a way to backup my phone data [w or w/o TWRP] before ROOTING my phone with TWRP (format data partition to decrypt, install no dm verity and install super su)? This is so after my phone is rooted, I can restore all the apps, pictures, etc.
Thank you for the help! :fingers-crossed:

Hi,
Thank your forwarding me to your thread. I think I figured out a way to fully back it up with the following steps:
1) If you are in Nougat, downgrade to 6.0.1
2) Root your phone by flashing CF-Auto-Root in Odin (it should not wipe any data)
3) Once phone is rooted, you can backup your phone with TitaniumBackup or Flashfire
4) Save the backup in your sd or other external
5) Update phone with official or custom Nougat FW
6) Root phone via custom recovery (TWRP), will have to format all your data
7) One phone fully booted up and rooted, restore from backup with TitaniumBackup or Flashfire
Let me know how it goes
Hello,
Today I tried to root my Nova and somehow I managed to delete the system while doing that. I don't know how or when, I did wipe the phone at some point, but left system unchecked. So now it is stuck in an endless boot, I just see the orange "Your phone is unlocked and not safe etc" message, nothing more. I can access TWRP and fastboot, and tried to use the LineageOS 13. But it failed, it told me I need a CAN-model, and mine is "generic_a53". So I figured I'll just put EMUI back on it, but I can't seem to find a working version for my phone. The huawei-website is pretty useless in that regard, they don't offer it. And the HiSuite-recovery just said that my model is not supported anymore.
So.. help? I know I screwed up and should have made a full backup, but I never figured I'd screw this up so spectacularly.
EDIT: Okay, I just clicked on "Backup" in TWRP, out of curiosity, and it said that "System" is 2516mb, but "Data" is 0mb, so maybe that's what's lacking?
Seems you are using the wrong TWRP. Use the one made for lineage. Also, what is your exact model number, you should be able to recover that way. My guess is you wiped data, factory reset, or formatted data. You could try using the backup made by bluesmoothie to restore data. You will have to search around this forum as I can't remember exactly which thread it is in.

Just like @wangdaning said, you're using wrong TWRP.
If you wanna flash LOS13, you gotta flash the TWRP mentioned at requirements.
It told you that your model is "generic_a53" because you're using "twrp_huawei_generic_a53.img".
To restore your phone, try to restore the backup made by bluesmoothie.
1) Download the TWRP backup (emui 4.1) made by @bluesmoothie from here: https://www.dropbox.com/sh/qrk0fbpn...ffYdia7raa/TWRP/BACKUPS/FPFDU16930014596?dl=0 . I had to download the files one by one, as I couldn't download the whole folder because dropbox was telling me that it's too big. After you've downloaded all the files from backup, put them in a folder named 1970-03-18--16-40-58_CANC432B100.
2) Download this recovery: https://www.androidfilehost.com/?fid=745425885120713827 , which is made by @Grarak.
3) Make a backup of boot.img so a folder will be created at TWRP > BACKUPS (e.g. FPFDU16A20001907).
4) Place the TWRP backup folder into the folder created at step 3). So, it'll be like this: TWRP > BACKUPS > FPFDU16A20001907 > 1970-03-18--16-40-58_CANC432B100.
5) Restore the backup.
Okay, it was the wrong TWRP, now that I flashed the recommended one, I was able to install LOS13, and now everything is working again. Thank you very much guys!
