F48 OLED screen flashing bootloader V2

[thommo75]

Hi all,
Both my F48 were losing all data and getting stuck when trying to boot everytime they lost power. Today i tried to do the firmware upgrade to both and. now both are flashing bootloader V2 on the OLED screen. I can't factory reset or do anything. They both now just flash the same message. Anyone seen this before and know how to fix it?

insert sd card with v2.59 fl2 file on it

Tried that and no difference. Wont detect the bootloader program on SD card

[darylc]

try formatting your sd card or another sd card?

Cheers Daryl. That and V2.58 got it going. Not sure how I stuffed it up but cheers for the reply and support.
