Hi guys, a friend of mine had a problem with his Moto E XT1021 and I'm trying to help him. I'm stuck on this screen and i don't know what to do:

AP Fastboot Flash Mode (S)
...
Battery OK
Devis is LOCKED. Status Code: 0
Connect USB Data Cable

...

failet to validate system image
Fastboot Reason: Fall-through from not charger-boot mode

He told me that he started to have problems after updating his phone. Whatever I do, I get:

failed to validate system image
Boot up failed

I tried to unlock the bootloader, but when I type fastboot oem get_unlock_data I get this error:

(bootloader) Could not get unlock data! OKAY [ 0.166s] finished. total time: 0.173s

...any suggestions? Thanks.

I tried but I get this error when i type the flash boot command:

C:\...\XT1021_CONDOR_RETEU_5.1_LPC23.13-34.8_cid7_CFC.xml>mfastboot flash boot boot.img
target max-sparse-size: 256MB
sending 'boot' (10200 KB)...
OKAY [ 0.398s]
writing 'boot'...
(bootloader) Preflash validation failed
FAILED (remote failure)
finished. total time: 0.463s

The smartphone shows: "hab check failed for boot"

...it is possible that I downloaded the wrong version ? :confused:

I'm assuming you're using Indian variant. So according to that you're using correct image.

Did these commands returned okay?

mfastboot flash partition gpt.bin
mfastboot flash motoboot motoboot.img
mfastboot flash logo logo.bin

mfastboot flash motoboot motoboot.img
mfastboot flash logo logo.bin

Yes, they returned okay. When I type mfastboot flash boot boot.img, I get "failed".

Why are you assuming that I'm using the Indian version ? The phone was purchased from Amazon in Italy and I was trying to flash the stock retail EU 5.1
I tried the 4. KitKat but i got some error about downgrading.

What you actually did, before this problem was caused?

Were you using the same rom(that you're trying flash) ??

It's not my phone, but he said that after an updating (was a normal update. I suppose it was the 5.1 update) he started receiving this problem.

That's not done dude. :mad:
It shouldn't have fixed your device the main part was this
mfastboot.exe flash system system.img_sparsechunk*

and that returned Failed too. Since the bootloader isn't unlocked so flashing custom recovery isn't possible too.

There's no other way I can see but device is bricked.

  • #15
So is it impossibile to unbrick it?

Hi, did this get resolved? I have the same problem. My XT1021 (UK Tesco variant) had been switched off for some time. When I turned back on it was looping in fastboot. Could not even turn it off. I tried flashing with a number of stock ROMs using usb to PC and mfastboot commands. Many stock ROMS caused errors on various commands, the 5.1 UK Tesco variant seemed to work perfectly - no errors displayed on phone or PC. But hone now boots too fastboot and shows the failed to validate system image error. Battery is apparently OK .. is something else likely to be toasted?

Its an old phone but would be good for my son as he starts senior school until he has proved he won't lose it ;)
