Hi for everyone! i need some help. I flashed my huawei y635 phone with a cm12.1 rom . the process was completed but when i reboot it enters to twrp recovery instead of load the system. the rom is ok because i proved before in the same phone.
I tried to swipe the cach, dalvik cache, data and reinstall the rom but didn't work.
this line appears when i install the cm12.1 rom:
... detected filesystem ext4 for /dev/block/bootdevice/by-name/system

I would be grateful for any help.

Hi guys, yesterday I tryied for the first time to update franco kernel's last update via FKU Beta and as a resoult my phone won't start anymore. When i power it on it get stuck on the boot logo (the one right after the cyanogen logo with powered by android). I can access to TWRP and i can access to adb but usb debugging it's turned off I think (is it possible to verify it?).
Inside the phone there is a very recent TWRP backup (yes, I tryied already to restore it from TWRP but no changes) and a Titanium Backup of all my apps. Is it possible to save it somewhere? What can I do to fix my phone?
Pleeeease help me Thanks in advice!
Which partitions are backed up in your TWRP backup?

ok I flashed my phone from scratch so now I have r33 on it.
I restored an old backup but now I can't update to r38!
That's the log of twrp

You had Franco kernel installed at some point? The remnants are screwing with the OTA. You need to clean flash with a full wipe.
Transmitted via Bacon
yes I had franco so i made a clean flash of r33, wiped cache and dalvik then i tryied to flash r38 with that error
Wiping cache and dalvik isn't enough, you need to wipe system/data/cache/dalvik cache, then install clean 33R, then you can take the 38R update. Or you could just flash the full recovery flashable version of 38R after wiping system/data/cache/dalvik cache, that's probably the easier solution.

Format data and fully wipe
You just erase or deleted files on your internal memory. But no biggie, just flash firmware with Odin (on windows) heimdall (on Linux).

Ignore the cpefs error, it's erroneous and will be fixed.
As long as you can mount data you are good.

How to ... Unlock Memory and have Root on the J710MN with Nougat 7
https://forum.xda-developers.com/ga...d-7-nougat-t3674417/post73826249#post73826249
hey i have solution
first 1. flash letest twrp
2.flash magisk 19.2
3. reboot system
100% done
I had LinegeOS installed on my xperia. But don't have root. I wanted to install root addon, but didn't have TWRP because previous time I just temporary boot with
fastboot boot twrp.img
Now I do the same fastboot boot twrp.img
and flash the root addon. I got this error Failed to mount /data invalid argument but also got successful flashed or something like that.
When I press Reboot > System it reboots in TWRP
I tried to flash LineageOS but I get error:
Code:
detected filesystem ext4 for /dev/block/platform/msm_sdcc.1/by-name/system could not detect filesystem for /dev/block/platform/msm_sdcc.1/by-name/userdata, asuming f2fs
mount: failed to mount /dev/block/platform/msm_sdcc.1/by-name/userdata at /date: No such device unmount of /data failed: no such volume
Patching system image unconditionally
Updater process ended with signal: 7
Error installing
Failed to mount /data
Is there a way to fix that without losing data ?
In TWRP file manager I see the system folders
try to boot on the latest twrp by fastboot boot twrp.img then wipe system then try to install the rom again.
copy the twrp.img to the internal memory
After booting download and flash the latest SuperSU then install terminal then type "su" then grant root access, then flash the TWRP on the FOTAKernel PArtition by
dd if=/sdcard/twrp.img of=/dev/block/platform/msm_sdcc.1/by-name/FOTAKernel
Hello everybody. I need Your help.
I have Lenovo P2. 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
