Hello. Please help to repair the bootloader. Smartphone does not turn on at all, we can also enter into flash mode. I was in the rom 5.0.1.
So i found some firmwares of my moto g xt1028 and tried to flash downgrade it to 4.4.2 but not successfully. After that, i tried to back to 4.4.4 and now stuck at this message:
- "failed to validate system image"
- Fastboot reason: "Fall-through from normal boot mode"
Any idea how to let me back as it is? :crying: Please help
P/s: I tried to flash 4.4.4 firmware again and many times, seem like all commands are proceeded properly but still cant boot , i wonder if 4.4.2 version do anything with it :crying:
Update1: Fixed! <-- I found there's 1 more file named "system.img_sparsechunk4" and decided to flash it ---> Fixed the device. Thanks god :highfive:
Downgrading via fastboot is very dangerous as you are also flashing the Bootloader. Is your Bootloader unlocked? I haven't followed if that's possible with XT1028.

Hello, yesterday I was trying to downgrade from MM to LP using Fastboot and by mystake I flashed "fastboot flash partition gpt.bin" and it failed, the others commands failed as well, after that I was unable to turn on my device, it only let me access to Bootloader Mode and also shows the battery charging, cannot access to recovery, and it shows black screen when I try to turn it on.
My phone is completely stock, It has neve been rooted, stock recovery. Its a Moto G XT1540. the Bootloader is locked.
Is there a way to bring my phone back to life? What can I do?
I also tried to downgrade my software n i got the same problem as you do but i have a rooted n unlocked bootloader device so i first installed cm12.1 so after that i got the 5.1.1 then i flashed the stock firmware 5.1.1 n i got the stock 5.1.1 system running very nicely
Provide a fastboot log (copy and paste command prompt screen) of what happens when doing all the fastboot commands mentioned in the tutorial. Take screenshots if necessary.

My problems concerns a Moto E 2015, but I think it could also occur on a Moto G 2015. I hope someone has experience with a situation like I have.. The phone is in a state where I can't accomplish anything
I think I bricked my Moto E 2015 (XT1524) yesterday. I tried to go to stock from cm13, every factory flash I did resulted in a "unlock bootloader" screen bootloop (tried stock 5.0.2, 5.1.1 retail europe). Then in a brainfart moment I locked my bootloader while a (bootloop causing) 5.1.1 rom was installed. This caused that I am only able to flash that particular 5.1.1 rom, otherwise I get a "preflash validation failed". The problem is that this 5.1.1 rom is not working so I can't boot and configure OEM unlock. I am also not able to flash another factory image, since it is blocked by the bootloader. I think I am out of options? I tried flashing the 5.1.1 rom according to the instructions (http://forum.xda-developers.com/moto...mware-t3044936). The 5.1.1 rom I am refering to is called:
XT1524_SURNIA_RETEU_5.1.1_LPI23.72-66_cid7_subsidy-DEFAULT_CFC_.xml.zip
With my current bootloader it seems that this rom is the only one I can flash... Is my phone bricked?
edit: I forgot to mention, I can only boot into fastboot mode, no twrp recovery nor stock recovery (I can flash it to the phone though). It just immedeately boots into fastboot mode (i see a short flash of the "bootloader unlocked" warning, then fastboot).
Hi all,
Please help me with this, i have a Moto Maxx with locked bootloader, it was into 6.0.1 brasil and it was downgraded to 5.0.2 Chile without being bootloader unlocked. now it is looping into fastboot mode with the following log:
Version downgraded fot boot
Failed to validate boot image: ret=-4
Fastboot reason: Fall-through from normal boot mode
Version downgraded for boot
failed to validate boot image: ret=-4
Boot up failed.
It is not recognized by fastboot devices, it stays into waiting for device.
In Devices manager it comes out as Fastboot quark S
if i put the qualcom drivers it happens the same.
i been trying with different tutorials but as it is not recognized by fastboot or ADB i only go to a dead end., if anybody has a way to fix this will be apriciate.
Please help me with this to recover this phone.
Sorry about my english.
Regards

1) You can not downgrade firmware on these Quarks with a locked bootloader. On the XT1225 and XT1250 Moto Maxx, bootloader unlock is FREE through request to Motorola website.
The first thing you do on these phones is unlock the bootloader! Unlocked bootloader is "god" mode.
I explain how to do it here:
UPDATED GUIDE: How to unlock your MOTO MAXX/MOTO TURBO bootloader/install TWRP/root
https://forum.xda-developers.com/moto-maxx/general/guide-how-to-unlock-moto-maxx-moto-t3455341
Even with an UNlocked bootloader, to downgrade firmware you have to omit the gpt.bin flash command. So, you probably still would have temporarily bricked your phone, since you don't seem to know anything about this phone -- but you could have easily recovered by re-flashing again. Unlocked bootloader is very forgiving!
I hate to sound this way, but you really, really should have even done basic research on this phone before trying to do what you did.
So, how can you fix this?
2) Your only way to recover your phone is to re-flash same firrmware you were on or newer. In this case, it would be the Brazil 6.0.1 firmware, and it would be good to make sure you flash the very newest -- because it needs to be the same bootloader version or newer.
This is the most recent Brazil 6.0.1 stock firmware:
XT1225_QUARK_RETBR_6.0.1_MPGS24.107-70.2-2_cid12_subsidy-DEFAULT_CFC.xml.zip
https://www.androidfilehost.com/?fid=385035244224403573
3) You will need to use RSDLite or ADB. You said it will not recognize the device in ADB, so try RSDLite -- or try them both on another PC. Make sure you have the latest Motorola drivers for PC.

4) if you can't get any computer to recognize the device to flash in RSD or ADB, there are a couple of other unbrick methods for Quark, but I have no experience with them:
https://forum.xda-developers.com/droid-turbo/general/turbo-unbrick-t3139811
https://forum.xda-developers.com/moto-maxx/general/tuto-unbrick-xt1225-100-t3483623
Yes, one is in the Droid Turbo forum but Quark is Quark.
Good luck.
