CrazyFire : Bricked and can't go in recovery mode

[makz]

Hello !

I've just bought a action cam from amazon, a CrazyFire V3R, it's a crane-sdv with gc9305 LCD, i had some issue with the webcam mode so i tried to flash another firmware (i made a backup and shared it)
Unfortunately now the cam boot on a whitescreen and i can't go in recovery mode, i tried every button pushed while pluggin the usb cable, the camera still boot on the white screen and is not recognized on any computers (even tried linux while looking on dmesg, there's no usb connection)

Is there a solution ?

Thanks.

Hello,

Yep it's my factory firmware.

I've already tried everything, but the camera is never recognized, there's no new devices, and even on a kernel level on a linux, there's no new USB device when i connect it.

If i'm not wrong, the recovery mode is only led turned on and black screen (the screen stay off) with mine, plugging the usb with every key combination possible, the camera boot to a white screen with or without battery/sd card, look like there's no recovery mode or not easily available like other cameras.

you removed battery, removed sdcard, and press and HOLD UP button (not OK/shutter, not power/mode, not down) as shown in the video at TIME 13:38 ?
you updated 'recovery drivers' (not ADB) from "PhoenixSuite Drivers zip" in https://www.dropbox.com/sh/aylp0e0u6...J0pUdC4ba?dl=0 ?
you used Phoenixsuit to flash the original CrazyFire firmware?

please look again at all messages, pictures and videos in this other thread https://www.goprawn.com/forum/allwin...=4875#post4875 , starting at post #8.

Yep told you I tried everything. Without battery, no SD and up button

[petesimon]

ok. and what happens when you insert SD card, insert battery and no usb cable, and power on the camera normally?
