Can't mount Data Partition. - Huawei P9 Lite Questions & Answers

These last days have been catastrophic for me and my p9 Lite.
A thousand and one operations I have done ... I have had to reinstall everything via fastboot ... (cust, recovery, boot, cache, recovery, recovery2, syste m)
And still, I do not get it to boot ... I still have hopes, because being in Revolution Nougat Recovery B.9 (or something like that) shows me the 3 partitions of the P9 Lite. (CUST, EXTERNAL SD and INTERNAL MEMORY) this last, says to be totally empty ... (0 MB) But when I give wipe - internal memory - repair partition, it tells me that there are 16 gs free.
When I want to change the format, to repair it ... it gives me error. Both F2sF and ExT4 ...
I think it may have been deleted in the internal configuration of the cell, the route to the DATA partition. Because I can not repair it in any way ... it always throws me wrong ...
If you like the challenges, here's a big one.
I have googled the possibility of re writing the path to the data partition via fastboot, I only get examples of Google Nexus 7 (which apparently in nexus 7 if it can be done), but none of P9 Lite.
Later I will upload screenshots about the errors that the revolution recovery throw me ... (if anyone is willing to help)
At the moment, I am without an operating system. I have access to huawei recovery, also to revolution recovery and I also have fastboot access.
In the eRecovery, when I try to download the complete package ... it throws me "error in the package", putting the UPDATE.APP of the B371 in the dload folder, the update goes up to 50% and then I throw "error in the package".
I hope they help me and that together we can find a solution to my problem.
From already thank you very much.

I think the only solution is to flash firmware via dc-phoenix

Try to flash stock recovery and do a factory reset, maybe it will work
Otherwise buy dc; phoenix (it costs 15€ i think) and it will write nougat firmware b370

If flashing recovery via fastboot isn't working,
Download whatever version of revolution recovery
Extract it, remove file_context , replace recovery.img by the recovery that you have downloaded,
Archive meta-inf and recovery.img
Flash it through recovery
Hope it will works

I am stuck with a similar issue, but Meticulus TWRO 2.8.7.0:
I get Failed to mount '/data' (Invalid argument) and Unable to open '' to wipe crypto key
I can neither wipe /data, nor format it, nor do anything else with it.
I tried flashing stock ROM and tried factory reset over there: it failed
I went back to stock B160 from CM13, recently.
Somehow I did wipe /system in order to run an update, which did not work.
So I got deeper and deeper into this trouble.
At the moment, there is CM13 without /data und unable to wipe /data in any ways.
I do not have a SD at the moment.
Would it help to put a complete stock onto SD and install it via update mode?
edit:
I could install an old system backup, which did boot and after flashing stock recovery I could factory reset /data

You might not know this, but every device has its own different system partitions. The thread you were referring to is for Asus Transformer Pad. Following that might make the problem worse.
But this is ASus phone it works on lenovo a6000

In that tutorial mmcblk0p8 is being formatted because that memory location has the /data directory on Asus Transformer. But, in our device the /data can be in any other partition, and doing that might brick the device permanently
Delete the recovery log from twrp folder and flash another twrp from flashtool or rash..what version are you using? If it is indeed a corrupted partition, you can reflash your phone using qfill
Try using the Fix Permissions in TWRP recovery...
It may help.

Best way is install the latest twrp I.e 3.0.2 and do the format everything instead of advanced wipe. Your problem will be solved. I too faced the same problem and I did what I have advised you. It worked.

Is the problem resolved??
I have solution
Bro don't take so much tension , thats not hardware problem its only your Recovery's reading cache error . you can simply fix this by flashing old version of recovery and from that old recovery again wipe what you want to remove but man don't touch your mount section column , after wiping data and anything else simply flash new twrp.img then simply reboot recovery . wollllaaa you got your partion cache back now again you can simply flash you favorite roms. I hope you understand what you have to do now . But please follow these steps carefully :good: .
Remember don't flash KitKat recovery over lolipop recovery otherwise you got bootloop. Old recovery means suppose if you have now twrp v 3.1 just simply flash v2.8 then after wiping things you want , then simply flash twrp v 3.1 .
If you still have any doubt you can contact me via WhatsApp - +91 9205097520 (indian no. ) or simply reply me on xda or simply mail me at - [email protected] . And at last don't forget to tell me about your device problem .

Help needed! Firmeware CAN-L11 EU Version

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?

@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

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?

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...

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!!!!!

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!

Recover Stock [unroot] VNS-L31C432B160

I just rooted my P9 lite, installed TWRP from the SRK Guide in here and then saw that Snapchat checks for root.
So now i would like to unroot (doesnt work in SuperSU), install Snapchat, Root und save with TitaniumBackup.
How does the process of returning to stock work? Where do i get my .zip?
I understand that i need to download my full ROM [Firmware Finder APP] but how do i procees further? Do i need to have stock recovery for dload method?
The unroot option in SuperSU does not work? :/
Download the stock firmware from here: https://forum.xda-developers.com/huawei-p9lite/development/stock-firmware-links-t3468245
Extract the dload folder which has the UPDATE.APP inside, put the dload folder in your microSD card, power off the phone, hold power button + volume up + volume down and wait until the installation will start.
This will relock your bootloader and restore the phone to stock firmware.
Does it matter that i have a ****ty twrp installed which doesnt even recognize data partition?
And can i unlock bootloader and root the samw way as before?
Thanks in advance
Wims
You can unlock and root as you already did. Which TWRP are you using?

I had a ****ty one from the Guide with the srktoolkit. Now i updated to TWRP v4 by METICULUS. It works and i can finally see /data/media again.
Does the Phone Off then 3 Button trick go through the Recovery or through what exactly?
I would now do the thing above, then unlock my Bootloader again (i still have the key so it should be easy), install the TWRP by METICULUS, install my apps i need to install without root (Snapchat) , then reboot to twrp and flash newest supersu from chainfire. Finished. Am i right?
Btw i have to say that i was pretty much a flashaholic with tht Galaxy S3, Moto G and OnePlus 2 and it was never this tricky i think :'D
Well TRWP still doesnt get /data. I didn't encrypt anything but Twrp keeps telling me that it cant find it. And when i (select storage) (internal storage) it goes to /emmc...
At first the log says:
Failed to mount '/data' (mounted without encryption)
And the Screenshots were saved to /data/media/Pictures/Scrennshots insted of somwhere in the internal storage...
I fear of having my partitions mixed up somehow because when stock recovery couldn finish wiping cache and data too...
Probably TWRP can't mount encrypted Huawei data partition, the only thing it can probably do is to format it so basically a hard reset

EDIT: I tried format data -> yes -> and even there it said can't find /data partition.
Any ideas what i can do?? Everything works but i can't do anything in all the TWRPs...

[Possibly bricked] "Failed to mount /data" & no internal storage

Hello everyone!
I have a P9 lite VNS-L31 running 7.0.1. on EMUI 5.0.2..
However during a factory wipe, it stopped booting correctly and I can't get passed from neither bootloader nor recovery.
I have TWRP Revolution v.260317 (TWRP 3.1.0-0) installed and my main problem is that for some reason the phone says that I have no internal storage whatsoever and if I try to wipe the /data partition it fails to mount it (error: Failed to mount /data (Invalid argument)).
I tried any of the methods in videos titled "how to fix unable to mount /data" (sorry, I cannot post links :/ ) but with no luck.
I can't seem to repair nor resize nor change file system of the /data partition. When trying to repair data using e2fsck it gives out the message:
" /sbin/e2fsck -fp process ended with ERROR: 16"
Any ideas?
I can use recovery and fastboot if necessary.
Regards

Well, more or less, but I managed to solve it!
I found out that the reason why it said there was 0mb of internal storage was because the bootloader that was previously unlocked turned itself locked, that's why it couldn't mount the /data partition. I just used SKR Tool to unlock the bootloader and after that yes, I installed that version of TWRP that you linked.
I also found out that the Revolution TWRP installed in the eRecovery partition (/recovery2 ?) instead of the normal recovery partition. What image is supposed to be installed in that partition?
That is the second recovery partition (another recovery) aka huaweis last ditch attempt to fix a broken phone. There's no actually problem if u don't have it-as most of the time (in my experience) its utter garbage, but there's no harm in flashing it if u want.
U can extract it from ur update.app file using huawei update extractor.

Yeah, I tried to install the RECOVERY2.img that I extracted from the UPDATE.app and it didn't work so I just didn't bother and installed the TWRP again.
But at least everything is solved!
Thanks
