Hmm, what happened to your device before this - were you using the device? Does your device stay in fastboot mode if connected to power or does it reboot after 10 seconds?
How is your device recognised when you connect to your computer, is it Qualcomm HS-USB9008?
What happens when you try to boot to TWRP?

i do flash a custom rom but it fails in a bootloop

i connected to the power he stays on fastboot secure mode but after a while he reboots until 10 seconds

Not recognised when connected to my pc, no qualcomm

Okay, the blankflash may not work as your device already had fastboot, it won't work unless you could boot into emergency download mode (EDL). Thus, your device doesn't appear to be hard bricked but it's failing to boot properly.

Hmm, the fact your device reboots in fastboot mode even whilst connected to power is troubling, which may eliminate a battery or battery contacts issue (might still be worth investigating). Did this happen suddenly or was it getting worse? Was your device dropped?

I see from your other post that even a stock ROM flash fails, which may suggest a hardware failure. You may have to consider taking your device to a service centre if there aren't any more ideas.

But also when i see the sparkles i try to reboot and he reboots immediately. The battery was able to charge. And then i lost the emei and i decide to flash the custom rom i had backup last day. After tHAt he was in the fastboot flash mode secure.

Perhaps its not a hardware issue? what do you think?

What do you mean by sparkles? From the screen or from the battery?

When you flashed the custom ROM, did it still boot into fastboot ( I'm trying to understand what you've done/what may have happened to your device)? With the IMEI, was it lost before?

It's possible it's software that is the issue here, though the failure to flash a stock ROM and the restarts even when in fastboot do point to a hardware fault ( your device shouldn't reboot until about 5 minutes in fastboot mode). You could have a sticky power button, do the buttons feel responsive?

Yes when i flash the rom it boots into fastboot secure mode.

i think the emei was lost by flashing the custom rom.

the buttons are all responsive.

Battery sparkles are not good anyway - did you have the battery replaced and check the connections to the motherboard? I'm concerned that the battery may be damaging the motherboard, or causing power fluctuations that may explain your reboot issues.

If you can boot into fastboot, can you pull your getvar info please?
1)Boot into fastboot mode, connect your device to the computer.
2)Ensure you have the Motorola ADB drivers and the ADB/fastboot terminal. Open an ADB terminal on your computer.
3)In the ADB terminal, type 'fastboot devices' without quotes. Press Enter - your device should respond with its serial number.
4)If you get a response, type 'fastboot getvar all' without quotes into the terminal. Press Enter. Please copy and paste the info into a post here, upload it as a text file or paste it into an online clipboard (like Pastebin) and link the online clipboard here.
