Stuck at fastboot mode after trying downgrade xt1028

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.

[Completed] Moto G 3rd Gen bricked or not bricked???

Hi,
My phone went into a boot loop.
I can access the fastboot menu but the device is locked, I obviously now cannot enter developer options to unlock it
When means I can't unlock the bootloader, and without unlocking the bootloader I can't reflash the device. Bit of a loop of death
Any suggestions or is it a door wedge?

XT1033, bootloader, can't unlock, can't flash rom, and i really don't know what to do

So here's the history, one beautiful day my XT1033 (Brazil), starts rebooting by itself. Went online, found somethings to do, UNLOCKED THE BOOTLOADER TROUGH THE MOTOROLA SITE, and downgraded to 4.4.4, but I made the mistake of updating it, trough the normal motorola updater. It went black, wouldn't turn on, not even fastboot. Researched a bit more, did a blank flash and then I could access fastboot again. Problem is, somehow my device's bootloader got locked again, and when I tried to "fastboot oem get_unlock_data" , I would get a " couldn't get unlock data!".
So, now I can't flash a ROM , and can't unlock bootloader, is there a way to flash a ROM with it locked? Or to re-unlock the bootloader?
Pls help, I can't stand using a Galaxy pocket neo anymore, HELP ME.
GOD BLESS!

if you can access Bootloader i can recommend just reflash the original stock firmware and u can do that with locked bootloader.

Please help me make my phone work properly

This is the case, I have a problem with the Flash ROM, now the phone can go into fastboot, but there is no Recovery, and the phone's bootloader is locked.

You're going to have to give a bit more detail if you want help from this community.
For example:
What phone variant do you have?
What did you have on your phone when it was running properly? i.e stock android, locked bootloader, rooted etc.
What 'Flash ROM" do you mean a factory image or custom ROM?
What had been trying to do to your phone i.e upgrade from Android 9 to 10 by sideloading an image?
Had you previously unlocked the bootloader?
I'm not saying that I will ultimately be able to resolve your issues but the more info you give the more likely someone here will.

Now,my pixel 3 can not work,the bootload is locked.when I select recovery by fastboot,The phone noticed me can not find vaild operating system,the device will not start.

I used to unlock the bootloader, it is because I locked the bootloader that this situation has occurred.

Can you unlock the bootloader again in fastboot?

When I lock my devices bootload,then this devices auto wipe data, so I think oem unlock is not open.And I can not unlock bootload.
