TP-Link MR200 firmware update

@gurangax

I tried to make my own file, but i'm not so sure if it's correct, could you make a file to compare with mine?
I make a file with C2V1stock_dump and another with tplink stock fw_160412.
i have a doubt about C2V1stock_dump, i've saw the xml config data is located at 0x7C0000, but in the isp dump xml is located at 0x7E0000, into mtd3,4,5 read only partitios.
So, if i flash via tftp stock dump with isp bootloader, the xml data will be duplicated, could this be a problem?, could it be better to use a tplink fw to swap bootloader?.

Thx.
