infinix zero 2

[kellisis]

i have an infinix zero 2 or infinix x509
i got a notification to update
the update was about 81mb, so i quickly downloaded it
i clicked upgrade and after a while it wrote installation aborted

the phone restarted and it got stuck in recovery mode

this is what appears on the screen

( Android system recovery <3e>
X509-J5800-KK-20150605
Volume up/down to move highlight;
enter button to select

reboot
applyupdate
wipe cache
factory reset
restore etc)

i tried all except the factory reset because i want to retrieve my files.

please can anyone help me solve this problem. thanks.

Try "Apply Update" First
if same "Wipe Cache" and try again

I tried it
The full options are
“ reboot system now
Apply update from ADB
Apply update from sdcard
Apply update from cache
Wipe date/factory reset
Wipe cache partition
Backup user data
Restore user data”

tried all except the factory reset.
the backup even doesn't work, it starts and ends error, cannot write ....

the apply update from ADB is quite technical so i dont know much on how to do that

The full options are
“ reboot system now
Apply update from ADB
Apply update from sdcard
Apply update from cache
Wipe date/factory reset - [3rd]
Wipe cache partition - [2nd]
Backup user data - [1st]
Restore user data - [4th]

Try This :
1. Backup User Data to SD Card
2. Wipe Cache Partition
3. Wipe Data/Factory Reset [Flash Phone if Same]
