TWRP shows 0mb at Interal Storage - Huawei P9 Questions & Answers

Hello, I have managed to get TWRP running on my Huawei P9 (EVA-AL10) with Emui 5.0. Unfortunately it shows me at Internal Storge 0 mb, if I want to flash something. I've searched the Internet for a solution and there was that you should change the partiton. I changed it from ext4 to FAT, but then Emui says when I boot again that my data is damaged and I have to reset my smartphone. Then I had no choice but to use Huawei eRecovery to reinstall everything. I found nothing specific for my device, so I hope you can help me.​

Can access fastboot and Recovery, but cannot flash anything

Hello and greetings from germany,
I have a problem with my Moto G 2014 XT1068. I'm coming from rooted stock KitKat (Xposed) with open bootloader and TWRP 2.8.6.0. Everything seemed fine until yesterday, when the phone just went off (0% battery) and stayed at boot animation.
I've tried a lot of things, but the phone seems to be hardbricked:
- I can access recovery, but restoring does "FAIL" (restoring boot partition works, though). Restoring "system" aborts at about 18%, "data" immediately.
- I can access the phone through fastboot, but cannot flash anything. Whatever I do, the phone isn't changed. Tried reverting to stock (getting error when flashing gpt.bin, everything else seemed to work without errors, but no changes), tested flashing other recoveries (partition size mismatch, but that seems to be normal, whatever I flash, it keeps being TWRP 2.8.6.0), or even upgrade the bootloader (no errors reported at all, but no changes made to the phone).
- I can access the phone by MTP from TWRP, but cannot write to or delete anything from the internal SD.
Do you have any further ideas or is it an hardbrick?
Thanks in advance
René
Seems like the internal SD card is damaged, or there's a faulty partition table. Have you tried repairing and formatting /system and /data partitions with TWRP? Does it read external sd cards? If yes you could try flashing CM11 (because lollipop roms need an updated bootloader) from an external sdcard and see what happens. Also your backup could be corrupted, that's why it doesn't let you restore it at all.
As for the recovery, try updating your twrp to the latest version available (3.0). You can update twrp from twrp itself, just to see if it's fastboot's fault.
Wiped /system and /data. Didn't help. Wiping /data/media led to an error.
Is there anything beyond "wipe" to repair and format those partitions?
Thanks for the hints, will try updating TWRP and installing 11 this weekend, as external SDs can be accessed.
Greetings from Germany

Stuck on Language Screen

I am new here and I try to find out all this new stuff.
I rooted my phone H30-U10, i took a backup of my ROM with SPFlash tool. Then I tried to do a backup via TWRP on my SD but the phone could not recognize it (I formatted in all types). So I tried to do Factory Reset.
After that my Sd card is still not recognisable (shows 0mb and cant be checked) and also I have stuck on language screen at the start. I can not do anything except restart/power off.
I tried to make another factory reset or flashing the backup rom but without result.
Do you have any ideas / solutions?
I solved this issue with flashing via SPFT a basic rom B629.
Now I have to find how to solve the problem with 0mb of sd card.

try to format the SD card manually using PC, if it doesn't work format using TWRP, this might solve the issue.
Sdcard corrupted
Glad that you fixed your problem

Huawei p9 format Data from ext4 to f2fs fail

hi
i have a problem with formatting Data in twrp recovery on huawei P9 eva-L09C432B182
https://dl.dropboxusercontent.com/u/67361401/IMG_20170309_174811.jpg
ive tried this ROM:
https://forum.xda-developers.com/p9/development/rom-huawei-p9-newworld-7-tecalote-t3543296
and it installs, but i get message after boot:
https://dl.dropboxusercontent.com/u/67361401/IMG_20170309_180017.jpg
i can actually see navi bar for a sec and volume buttons still work(can set alarm and sound loudness)
and here is install image of Rom:
https://dl.dropboxusercontent.com/u/67361401/IMG_20170309_175844.jpg
only error is mount: failed to mount /dev/block/dm-0 at /dat: No such file or directory
so i can only use twrp recovery and fastboot to fix this.
mkfs.f2fs -t 0 /dev/block/mmcblk0p42 process ended with error: 255
unable to wipe Data.
error changing file system.
every other is good for format(System and Cache) to f2fs and ext4 just Data folder has problem with format but wipe works :crying:

Why you decrypted it?
It should work normal after you reset it.

reset what excatly? factory reset works but Data is in ext4 format. i can wipe it but cant format it.
what if i erase this mmblck0p42 file and then flash twrp in fastboot will the file be reinstalled or will it be after i flash ROM in recovery again?
i made a mistake by formatting it in first place from f2fs to ext4 but before even factory reset didnt work, now it works and only think is left is this encryption error.

Why is your data partition ext4?
Normally it is on each p9 device f2fs.
This can only occur if you were on Nougat between and had installed the TWRP-n which has no Decryption Support and if you had by yourself formated data with this TWRP to ext4.
To install NewWorld Rom you must be on Marshmallow Firmware (because of Android 6 Bootloader) and your data partition must be f2fs.
In the meantime there's a new TWRP for Android 7, which has already Decryption Support.
But you cannot use this TWRP for installing NewWorld. You must have the one, which I have linked in my OP.
On which Firmware or Rom have you been, before you tried to install NewWorld?
If you were on Nougat, NewWorld could not flashed, cause you must be on Marshmallow.
Please answer my questions that I can realize in which situation you are.
i have Marshmallow Firmware and yes i formatted data to ext4 myself
the problem occured when i wanted to get nougat but OTA update failed but it booted back into 6.0 normally just root didnt work so i went in TWRP and flashed supersu 2.79 which i had before, then i was stuck in bootloop, manged to get to fastboot but Hisuite says no update packeg for this phone. i flashed back stock recovery and tryed to factory reset but didnt work, flashed twrp back and factory reset then it said data format error so i went and changed it to ext4 after factory reset worked but i cant put it back to f2fs.
aldo i wiped all cache, dalvik/ARTcache, Data, internal storage and system

Okay, you are now on Stock Marshmallow (which version?) and you maked factory reset after formatting data to ext4
Which phone EVA model to you have?
It is recommended to flash Stock Recovery with adb and flash latest official Marshmallow Full Firmware once again (downloaded and unzipped) with 3 Button (Force Update) from the folder dload on your phone (update.app and if present meta-inf must be in this folder only) Force Upgrade to Marshmallow Firmware should solve your problem (Bootloader get closed, data should be formatted to f2fs automatically)

thanks soo much i did what you said on pm. went to bootloader and flashed your twrp then wiped again arpcache, cache, system, data, reboot to twrp then installed your ROM which still said that mount dev-0 error but i still rebotted and bam it booted longer with this very nice animation you have and showed emui and now im at select language page!
Flashing your twrp in bootloader fix the problem and formatted Data to f2fs thank you again.
also i used command recovery --wipe_data --set_filesystem_encryption=off before all above to make sure ecryption is off not broken.
im now on home screen it looks nice just 3 navigation buttons on bottom look smaller then i had before, thanks again.

Lenovo K3 Note k50-t5 internal storage mount issue with 0mb internal storage

Hey Guys I need some help ...!
Recently, found some issue on my Lenovo K3 note k50-t5 with custom blend rom marshmallow version stuck on lenovo logo so i tried to format everything with twrp (DenisePDA 3.0.2-6v4) version on my phone but unfortunately I am facing more issue afterwards as I've got No OS Installed/No Internal storage/No SD card it was showing everything empty the only thing I can access on my phone now that is to reboot on twrp with 0mb internal storage. I can't mount Internal Storage nor SD card but I tried to flash another version of twrp through OTG but no success. I also tried to change the file system from ext2 to ext4 but it failed. I tried everything like SP Flash tool to get back on Stock Rom but No success as it was showing BROM Error (4008). I also Tried to Re flash twrp with Fastboot method but all my attempt was failed. I hope if someone help me out how to fix an unable to mount storage issue on my TWRP atleast I might able to Flash rom again. Please Help...! If Anybody know how to fix or overcome this issue.

Question TWRP 3.7.0_12 fails to decrypt storage on stock A11?

Hi folks,
So, i'm still on the Stock MIUI 12.5.7 (Android 11).
Before upgrading, i just wanted to check out if TRWP works correctly, so i flashed the most recent official version...and to my surprise, it could _not_ decrypt the internal storage?
Also, in the Backup menu, the EFS and modem partitions have correct sizes, but the dynamic Super partiton is shown as ( 0 MB).
I thought there would be no more issues with such old ROMs...or maybe I'm missing something?
UPDATE:
After wiping data and resetting the phone, TWRP managed to mount the internal storage, as long as there's no PIN on it.
As soon as i enter a PIN in Android, the same PIN entered in TWRP fails to decrypt the internal storage.

Sounds like you need an OS reinstall preceded by data format, not wipe, to remove encryption. There is a Nebrassy 3.6 version that decrypts for A11.

It works with Orange fox.
Well, now that i have done a "format data" it works with TWRP, as well.
I moved to a xiaomi.eu rom, and everthing works fine, so far.
Also note that TWRP seems to always get replaced by the stock recovery when on a stock rom from Xiaomi.
