NEED PROPER SOLUTION I just flashed micromax q402plus (sc9832a) with factory download tool. (because upgrade download tool and research download tool both stuck at flashing system.img)
the phone is stuck at bootlogo so i decided to flash it stock firmware. so i flash it with SPD_Research_Tool_R4.0.0001 but it stuck at flashing system.img for long time and failed. so i flashed it with SPD_Factory_Tool_R23.19.4001 and succefully flashed but my imei is changed so i repaired it to origional one. when i inserted SIM back , it does not show any network ,only emergency call. My baseband and imei is ok and my sim card is recognizing but no signal. (this is the same rom i flashed earlier to this phone)
i dont have its nvbackup so tried to restore other phone(same model) twrp backup file (ltemodem) to this phone.but the sim slot not detected any more.
i tried to flash nvitem.bin backup from other phone to this (backup from research tool and rewrite imei) but still no network.
someone advised on net to flash it with SPD_Upgrade_Tool_R22.0.0001 ,but no luck .
i did factory reset twice after flashing i have no idea about how to fix it
