I have rooted my device running 2.3.3. I hv installed xrecovery. I installed update.zip using xrecovery. But when I'm Trying to install a custom rom from xrecovery this is what i get :
"Installing: SDCARD: X10-CM7-V011-XperiaArc-theme.zip
Finding update package...
E: Can't move /dev/block/mmcblk0p1 (or/dev/block/mmcblk0)
E: Can't mount SDCARD: X10-CM7-V011-XperiaArc-theme.zip
Installation aborted."
Now, When I go back to retry or Report Error or Install Update.zip... This is what I get:
"E: Can't mount /dev/block/mmcblk0p1 (or/dev/block/mmcblk0)
(Device or resource busy)"
I am helpless guys!

EDIT: do you have the good version of xecovery xRecovery_0.3_GBready ? you should install it with flashtool
FIRST: make a backup, before to flash a custom rom
read carefully instructions in threads, you have to wipe delvik...stuffs like that

No worries ,
Just Download the latest version of flashtool i.e. 3.0.0
Enable USB Debugging on your phone
Enable Unkown Sources on your phone
Install X10 ADB USB drivers (included in the .zip)
In flashtool - Ask root perms and install xrecovery
Youre gold then
Ok spaarc and chriscx... M gonna try them.

Honor H60-L11 [Android 6] Successfully installed SuperSU via TWRP but failed to root

Hello,
Today I flashed TWRP recovery and successfully installed SuperSU, both the lasted version. The log in the end shows
Code:
unmounting /system and /vendor
done
updating partition details...
...done
and I press the button [Reboot system].
Although during the installation, it showed "the first reboot may take a few minutes, and loop blah blah..." But actually, there was just one reboot and no SuperSU icon in my phone. So I manually installed SuperSU app from google play. But SuperSu warned me that my phone is unrooted.
Can anyone help me with that? Now my phone remains the same, no errors. Why I can install SuperSu but cannot root my Android phone?

Problem rooting refurbished google Pixel 1 with magisk (failed to mount system/root)

Hi,
I just got a second hand Google Pixel 1 and I ran into some trouble trying to install magisk on it : I keep getting those two error messages in TWRP when flashing the TWRP.zip and magisk.zip :
"Failed to mount system/root (invalid argument)"
"failed to mount vendor (invalid argument)"
The two installations are still considered successful by TWRP but rebooting after flashing the magisk.zip keeps the phone in bootloop.
Any idea how I could fix this please ?
Information on the device and software used :
- android 10 installed on the phone when i got it ;
- bootloader unlocked, usb debugging on ;
- Flashing TWRP with "twrp-installer-3.4.0-0-sailfish" preloaded in the phone and the corresponding img ;
- magisk manager installed and using magisk 20.4 zip preloaded in the phone for flashing ;
- all commands made in cmd.exe from windows 10 computer ;
- adb and google drivers installation all ok.
please ask if I didn't give enough information.
Thanks in advance !
