Can you get the original firmware that the camera came with? There's a chance that loading it back via the SD card might get you going again. Not sure which processor this cam uses but some (I think Novatek but I'm not sure) processors can be unbricked via other firmware which is available, then you can reload the original afterwards.

Either way you will need the correct firmware so you should ask your seller if they can provide that.

Rebooting can be caused by low power input. If it happens again, try running the cam on a home-type phone charger or powerbank, and if the rebooting still happens there it may be a bad battery or bad supercaps in the cam.

now my d201 is rebooting. How can I fix it?
If you have a DAB201 without the letter S, then the processor is A12LA55, and you have downloaded the firmware designed for the processor A12LA75, you can see the information here https://dashcamtalk.com/forum/threads/what-is-difference-between-dab205-and-dab205s.28004/ and here https://dashcamtalk.com/forum/threads/newbie-q-whats-the-diff-between-201-202-and-205.26292/.
In any case, the dashcam on the Ambarella processor can be restored using the DirectUSB program, you will need a file with the .elf extension, although it is possible that firmware via a SD-card can help

PS: I just saw that everything was fine! ;)

Looks like you already found what you need? :woot:
Can you share where this firmware came from, and even with a gift in the form of an elf file?

You can also check this MOD
https://drive.google.com/open?id=1SMFaZSr_iJF054EQC-YEvPa3N7uK8Wt4,
although it is made on the based of not the latest firmware - 20160405a_DAB201_A12a55_gps_zhongxing_v2385 (with correction of brightness tables + 100% of the initial values).
