Restoring IMEI on the Lenovo Tab A7-30 (A3300HV)
Flashing experiment with unexpected results
My recent experiment in flashing the Chinese firmware for my Lenovo Tab A7-30 to the European version resulted in an error in the IMEI or International Mobile Station Equipment Identity; a 15 digit number that is unique to the device.
Every time I input *#06# is brings the message INVALID IMEI and without a valid IMEI, your device will not be able to make calls, send text messages and other simple communication over the network.
Now, to be honest, this is a side effect of flashing I did not consider. Fortunately, restoring the number is not that difficult and thanks to instructions from Plus Droid (www.plusdroid.com) I restored mine.
Restoring the IMEI
For my device, the IMEI number was printed on the box so it was relatively easy to restore it. Also, I used a bemobile-Vodafone SIM on the tablet.
The first thing is to open the device in engineering mode. This is done with the following code *#*#3646633#*#*
Then swipe to Connectivity and tap CDS Information, then tap on Radio Information. Then tap on Phone 1.
Then enter AT+ EGMR=1,7,IMEI number and press SEND AT COMMAND. Make sure there is a space between AT+ and EGMR otherwise you will get an error.
Once the command is sent, reboot your device and then check the IMEI number again by using *#06#.
