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.

If you're facing No Service Problem even after IMEI Writing. This indicates that calibration data on your handset has been erased. To restore that, you need to copy/paste/replace system files from a working micromax a25 into your device.
Can you please share with us if you have?

Try doing it on another computer. Can be the problem of your Operating System. Else, try this
Open Device Manager > Expand Ports > Select MediaTekPreloader.. and Update Driver Software > Browse the Computer > Let me pick.... > Uncheck show Compatible Hardware > Select MTK USB Port in "Model Column" > Press OK > Reboot Computer (Optional) > Reconnect phone > There will be no error in flashing now.

Is your star h7100w rooted?
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.
