The device was in service for battery replacement, after failed update opver wifi, it started, left me to choose language and wifi, started dowlnoad and restarted endlessly. In the service shop guys aid the battery might be dead. Returned to me - now there is only "Updating" with 4 black squares and 1 white and "please wait" on forur different languaes - I prsumed failed update... If those idiots forgot the sd card... I am speechless.
Whatever, I have a spar sd card that I can format to try to revive it, so please send me pm with linnk to firmware - it is N250, there really is SD card holder on the motherboard, and there treally is NO card in it. Very strange situation. What I can do is try to burn SD card image on my card and put it in the slot see if the service shop is playing games with me
