[Please help] No Network After Flashing Micromax Q402Plus (SPD)
(22-03-2020, 08:10 AM)shankar1790 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
(23-03-2020, 06:24 AM)shankar1790 That problem solved due to I have backup nvitem from same phone. But not in this case
Factory download tool erase all flash from device and reflash all partition. I forget to backup.
I still don't understand why this happen. all WiFi, Bluetooth are working except sim network.
Signal strength is zero and out of service problem.
In *#*#4636#*#* sim network shows different provider than original jio -103db 35asu strength

look for another phone same model as yours to backup nv ; you can backup using research dl @ https://www.hovatek.com/forum/thread-31800.html
when flashing the nv backup, ensure to first goto settings > backup > untick everything there so it doesn't rewrite the old nv from the phone

(27-03-2020, 08:48 PM)hovatekyes, my neighbor village. i dont have 2g sim write now , i will try later. since i have 2 phone of same problem. one of the device is having problem due to flashing with factory tool and one of due to flashing twrp backup of same phone (i want to transfer/install my custom rom from one to onother).i have selected all partition in twrp (like boot.img, bootlogo recovery, ltemodem, misc ,pmsys ,system-image ) and restore it to another phone. after succesfully restored i booted rom but no signal atoll. imei changed to first-one , so i rewrite imei but same network problem(27-03-2020, 05:24 PM)shankar1790 that exactly i have done and rewrite imei but this problem persist
Was this person in the same region as you? and have you tried setting network to 2G only to see if you get signal.
I also suggest you do a full TWRP backup (all NV and modem related partitions in stock fstab) and restore to your device
(01-04-2020, 06:04 PM)shankar1790 yes, my neighbor village. i dont have 2g sim write now , i will try later. since i have 2 phone of same problem. one of the device is having problem due to flashing with factory tool and one of due to flashing twrp backup of same phone (i want to transfer/install my custom rom from one to onother).i have selected all partition in twrp (like boot.img, bootlogo recovery, ltemodem, misc ,pmsys ,system-image ) and restore it to another phone. after succesfully restored i booted rom but no signal atoll. imei changed to first-one , so i rewrite imei but same network problem
