Wich 1010 map for old XXL device

You've to be carefull with a Bootloader update, don't run out of power and/or don't interrupt the proces
You need the file system and put on your olde SD card and when still there overwrite the former file system
Be sure the battery is full loaded, better to use the powersupply too.
Reset your device and start, the update will be done into a split second, when you read the remark an update take place, it's finished before you'read the whole line.
Mind your mailbox, please.
