Hi guys,
I own an european AVH-X8700BT (4100NEX in US), and I stupidly bricked it trying to upgrade from v 1.03 to 1.053 with an USB stick and using that image - 15MY_FW-Update_v1.05_4G_20151216
Somehow upgrade process has failed, and no recovery was possible. I didn't backup the internal SD card, nor had it's password removed while the unit was still functional. Now it is staring showing Pioneer logo and after short period
is powering down. Please help, give me proper sequence and instructions how to de-brick. I can do JTAG nor flash if necessary, I am not afraid of complicated procedures...
I prefer to go straight to opened boot-loader and unlocked SD pass, but I will do any suggestions if possible.
regards
thank you in advance
