this is a bit funny but read it carefully please -
after download firmware 20160524 and redownload a Stock Firmware 20160314, at this stage automatically IMEI got restored automatically. i have no idea how this things work but it worked well. then again i choosed download firmware 20160524 but only and only i ticked on android. at this stage i am able to download new watch skins and also can connect to GSM network (vodafone or any).
but if i tried to restore in watch than after my watch works well apart than get connect to GSM. so what i do i again choose the Stock Firmware 20160314 and only and only tick “USRDATA” and after watch works well :D.
but restoring is always problem here. so after restore i have to repeat the process.
if any stage you guys get stuck and watch shows usb support error. open the watch and if unable to remove the battery than pick a small flat tip screwdriver and short circuit the battery connector only for the fraction of the seconds. and watch ready to work or ready to get deduct again.
i choseed to take a risk and worked but guys make your own mind before taking any further step. i am still waiting if any one could help me yo sort out the problem in genuine rather than i have to choose this repeated steps.
i am still waiting for to get a solution in relation to my very first comment.
Thanks & regards
