Tweak simply means cheat, or free browsing. Tweaking of an Android phone means changing of the Android phone IMEI to another phone IMEI to get free megabytes.
This is the best and easiest method for changing an Android phone's IMEI. The method does not require a PC, though you might need one to generate your imei. After that all you need is the mobile uncle App and the Android device you wish to change its imei to blackberry imei or any other phones imei.
How To Change Your Imei Using Mobile Uncle Method
>>Get your Android phone rooted, or do that Here
>>Download the Mobile Uncle App from play store Here or get the English version Here
>>Install, Open it up and go to Engineering Mode
>>Select Engineer Mode [MTK]
>>Swipe to the Right and select CDS Information
>>Select Radio Information.
>>Phone 1 represents sim 1 and Phone 2 Represents sim 2. So Tap Phone 2, you will see a command line like this: AT+
>>Now just add this line to it EGMR=1,10,"15 digit Imei No you generated" and click SEND AT COMMAND. E.g AT+EGMR=1,10,"35826501267XXXX"
>>If you are to change that of sim 1 click on phone 1 and change the command to look exactly like this AT+EGMR=1,7"imei No generated" While Sim 2 should be AT+EGMR=1,10"imei No generated" And you are done.
>>Reboot your phone and check the imei using *#06#
NOTICE:While changing your imei, should you get any ERROR RESPONSE like; "command is not allowed in user build". After clicking on SEND AT COMMAND, instead of the normal "Command is msent!" Don't panic. Just add One Space between the AT+ and EGMR... That is AT+ space EGMR... Or just copy and paste this: AT+ EGMR=1,7,"IMEI Num" Then replace IMEI Num with the imei you generated.
