Iocean x7s Re-write NV.Change imei and-At command is failed to send.
Hi I would like to ask for help-phone can not see both sim cards or the slot in slot 1 or 2 Well, I can not set the IMEI on your phone by going to settings by entering * # * # 3646633 # * # *. After entering the IMEI number and approval - displays to me, At the command is failed to send,,. Ioceana asked what to do and so I wrote back:
If there is no signal on your phone, it maybe Caused by IMEI or NV lost. You april check the IMEI Firstly, input * # 06 #, if the IMEI is lost or invalid, you have to re-write the IMEI. And you a small check NV to input * # 66 #, and press "SN", to see if NV is there, if it is blank That means you have to re-write the NV as well. (IMEI and NV maybe lost because of flashing ROM or factory reset)
maybe you should rewrite the NV
When the write NV, please ensure code That the version corresponds to your phone model.
Write NV tool (including guidance)
give it a try.
Can somebody help me how to do it exactly?
