XT1032 Bootloop after recovering backup

Hi everyone,

I was gonna update to a new version of CM12.1 (was originally using the 27/08 version, and i was gonna update to 30/09 version). So I made a backup, then I tried to restore it, because last time I updated, the update failed and the backup was bad too. So, I restored it, and then the phone went into a bootloop. When I tried to boot into Recovery (Fastboot -> Recovery), it would reboot and get stuck, then reboot again.

The things I did in order:
Try to get into bootloader a couple of times
Reflash TWRP in fastboot (fastboot flash recovery twrp.img, was version 2.8.6.0)
cmd: fastboot erase recovery
cmd: fastboot erase cache
Flash TWRP again
cmd: fastboot erase system
Flash CyanogenMod Recovery
I can boot into that now
Try to flash CM12.1 nightly 30/09
Factory Reset (Recovery crashes before it is completed)
cmd: fastboot erase data (I get this error in the cmd:
erasing 'data' . . .
(bootloader) Invalid partition name data
FAILED (remote failure)
finished. total time: 0.016s

I just get 'cmd: erase:data' with no error in the fastboot.)

So I think the problem is in the data partition, but I don't know how to fix this.

Thanks in advance!
