[Q] No app2sd

Hi everyone.
I am trying to wipe data/factory reset my phone through ClockworkMod recovery v2.5.0.7.
But when i press the trackball for it to be wiped, i get an error message.
"Formatting SDEXT...
No app2sd partition found. Skipping format of /sd-ext.
Formatting SDCART:/android_secure...
Data wipe complete"
And when i try to load a ROM after that i get:
"E: Can't mount /dev/block/mmcblk0p2
(File exists)
e:Can't mount SDECT:
E:Failure at line 11:
copy_dir PACKAGE:data SDEXT:
Installation aborted"
Anyone know how to fix that ?

No one? This is really important.

I have some problem...

you need an ext partiton.....maybe its corrupt, re-patition

Problems with data partition

Hi,
I tried to flash viperOS using squid twrp for moto G5S, but something in the process i think i did wrong.
My phone model is montana xt1790.
I unlocked the bootloader.
I tried to install the recovery, but had same problem than @dau999

Bootloader gives me a notification that the img is not signed or corrupt (squids one)

I tried to flash "no-verity-opt-encrypt-5.1.zip" file posted as solution here https://forum.xda-developers.com/showpost.php?p=74813124&postcount=23.
After this i have working the recovery, but i believe this is what did wrong:
With debug mode enabled, after a wipe clean (Cache, Data, Dalvik/ART and system) and format data (wipe all your apps, backups, pictures, videos, media and removes encryption on internal storage) got this errors:
Code:
Could not mount /data and unable to find crypto folder.
Failed to mount '/data' (Invalid argument)
Unable to recreate /data/media folder.
Unable to mount storage.
Unable to mount /data/media/TWRP/.twrps
Failed to mount '/data' (Invalid argument)
After this errors i flashed ViperOS, but after first boot it, first thing viper OS ask me was the phone password, after i enter it, the phone show up a message saying that password is ok but data is corrupt, restarting and trying to fix my phone without success (same errors like failed to mount /data)
Also i tried to use the "repair or change file system" selecting Data partition, twrp show me this: http://oi65.tinypic.com/2prin8y.jpg, also i got this errors:
Code:
/sbin/fsck.f2fs /dev/block/mmcblk0p54 process ended with ERROR: 255
Unable to repair Data
What should i do?, i don't know is related with an encryption on data partition, or if this can be solve.
EDIT:
Found the solution in reddit: www.reddit.com/r/AndroidQuestions/comments/7w5c75/used_the_format_data_option_in_twrp_recovery_on/
Just fixed the issue after making a second format in TWRP ( WIPE > FORMAT DATA)

Bricked because of encryption?

Today I tried to install Cardinal-AOSP on my Lenovo P2. I had no problems during the installation but after booting for the first time I got "Encryption unsuccessful" with an option to "Reset phone" to perform a factory reset so I selected this option. Phone rebooted but i still got the same "Encryption unsuccessful" message.
This is where the trouble started because TWRP did not ask my the password (swipe pattern) anymore to decrypt like it did before.
I can't wipe /data and also not repair or change filesystem. The errors I get are;
"Could not mount /data and unable to find crypto footer." and a lot of "Failed to mount '/data' (Invalid argument)".
In TWRP under "Mount" I can't select Data anymore.
I also can't install OS roms (.zip sideloaded) anymore because of the /data partition.
So OS won't boot because of encrypted /Data and TWRP won't let me mound the /Data partition to make modifications.
I still have full access to ADB and fastboot so that is my last hope.
Is there any shell command I can still try? Manual data formatting? Or maybe an alternative recovery?
Update:
So far I have figured out that /dev/block/mmcblk0p56 is the data partition and that "fdisk -l /dev/block/mmcblk0p56" has "Disk /dev/block/mmcblk0p56 doesn't contain a valid partition table" as output.
/dev/block/mmcblk0p56 has an entry in /etc/fstab: "/dev/block/mmcblk0p56 /data f2fs rw 0 0"
"mount /dev/block/mmcblk0p56" gives "Invalid argument" as output and so does "mount -t f2fs /dev/block/mmcblk0p56 /data"
Is it possible that I need to re-format /dev/block/mmcblk0p56 to f2fs? And if so, how?

Unable to format using twrp - Unable to format to remove encryption

Hello everybody. I need Your help.
Last days i tried some ROMs. I have TWRP and before every new upload i FORMAT DATA(Wipe) and of course wipe cache, system
Today when I try to format I have error:
Unable to wipe '/data' -- unknown file system 'auto'
Unable to format to remove encryption
when i typed :
cat /etc/fstab
i got:
/dev/block/mmcblk0p56 /data ext4 rw 0 0
I read some posts of forum and ?solution? to repair is to type this:
make_ext4fs /dev/block/mmcblk0p56
after this i had 0MB Internal Storage and many errors when try to format any data, cache, internal....
So i changed to f2fs and back to ext4 and Internal Storage is OK but still can't format data
Now I can upload ROM but when it starting i have monit "Encryption unsuccessful and interrupted"
PLEASE HELP i can't use my Lenovo :crying:
btw. my linux knowledge is not very well
