should flashing only boot.img work?
(10-01-2015, 04:00 PM)sagarpatel one problem here..
I tried to repack custom rom of some similar device and flashed (as per some porting tutorial). I also tried flashing that rom directly. as a result I got boot loop and lost cwm recovery.. thus I spflashed my mtk backup and recovered.
Problem is now I have lost in-call proximity. when I recieve a call and put on ear backlight doesn't get off. proximity sensor is not working. in engineering mode proximity sensor seems working. sensor reading changes when I put finger on sensor but calibration is failed.
I have tried reflashing spbackup with preloader ticked but the problem persists. I think sensor driver files are missing from sys/devices..
Everything else is working except call proximity. if anyone can help please.
1) cant find prox_cal at location "sys/devices/virtual/sensors/proximity_sensor/prox_cal"
2) there is nothing named adc values in engineering mode.
3) calibration, reset, calculate values, set threshold.. All Fails. Only values fluctuates while moving finger around psensor.
Why spflash cant restore proximity.. I have flashed thrice..
Thnx
