[flyboy_____]

Dear sirs

By mistake I loaded with Flash Tool v122 the MTK_AllInOne_DA_MT3329_v4.02 download agent and the AXN2.10_5156_3339_1152.1101000.10 firmware in to a Mediatek 3329 GPS (Skylab).

The problem is that my GPS is the 3329 and after loading 3339 firmware It does not work and when I try to flash It again it gives error:
[Flash Download]
Fail!!(Download) BROM_CMD_START_FAIL
[Finish]
Take(4) secs to test.
***********************************************
GOOD NEWS!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! SOLVED !!!!!!!!!!!!

The problem was Flash Tool v1.2.2 I used DIY DRones Flash Tool v1.0.0 and the GPS accepted again the correct firmware and its working :):):):):):):)

Tried again with Flash Tool v1.2.2 and the problem occurred again and solved i again with Flash Tool v1.0.0.

CONCLUSION....................
form Mediatek 3329 GPS is best to use Flash Tool v1.0.0 from DIY Drones

I'm no Guru.

Are you sure that you are selecting the correct download agent for your GPS chip?

I do not know version 1.4? were did you get it?
Try installing the MTK3329_A1.5E_20110118_10Hz_115200.bin.
Its the one that I'm presently using with good results

Power trick helped me quiet often.

Power on the GPS AFTER hitting "Download".
I flashed 3329 fw to a 3339 and rescued it that way.
