first save flex and if you can make a full backup of flash
to flash you can use test point, I think all 14.04 have intel ic because it you dont have problems to downgrade to 10.81, else if flash dont works you have to flash patched 10.81 for atmel ic's
before downgrading, if phone says "phone failed see suplier" you need to flex it with repair.fdf file
after this you have to flex it with saved flex file from v51 |
