Micromax A25 Complete Guide (Rooting/Troubleshooting)

Hello

I have flashed my Micromax A25 with A25_0201_V0370 stock firmware and my IMEI was gone.I replaced the IMEI by copying the MP0B_001 file and setting the permission to rw-rw----. But my phone always shows no service whatever SIM I insert. I have checked according to your post that my "Android Core Apps" is running. Please help me.

. This will brick your Micromax A25. Don't worry, after that you'll be able to flash anything you want. It is advised to flash stock rom before flashing any other file.


2. SIM Related Trouble Shooting/ No Service Problem/ IMEI Problem (Fix)
Use the above app to write the IMEI


If you're facing No Service Problem even after IMEI Writing. This indicates that calibration data on your handset has been erased. I've finally found a way to fix this problem. There's no solution for this problem on entire interent. You just need to replace the "CALIBRAT" folder with pre-configured Calibrat data and set that folder's permission to 777. Use Rootexplorer to edit system files. This fix has been found by myself. You will not get any solution on this problem throughout the whole Internet.

Yes, It's rooted. I asked for a nvram.bin to the seller for the same model of smartphone.I flashed it and everything ok(Imei. mac address, bar code, bluetooth) but the touch screen still uncalibrated. I erased the calibration data with sp flash tool. Alttafv said "You just need to replace the "CALIBRAT" folder with pre-configured Calibrat data and set that folder's permission to 777" but I don't have the pre-configured Calibrat data and I don't know how to get it for my phone.
Please help.
