    I have a sc9832a device  (model q402+) which is stuck on boot.I decide to flash it's stock firmware with miraclebox 2.82 (w/o box).
    But just give an error NV WRITE failed.so i used upgade down load tool ,its also give error on BKP-NV_FAILED( gsm calli.....) i tried to flash with factory download tool (9832)but its give error on BKP_NV (flash is damaged) .i finally decided to flash with reserch  download  tool but its also throwing error on BKP_NVFAILED .so i unchecked backup and flashed successfully but my imei is changed.
    But i have facing a strange thing with device its shows FOREVER LOCKED -emergency  call only with SIM instead of normal no network(due to invalid imei)
    I don't have its nv backup file so i tried to  flash my other device nv (same model) too but still same issue

    how did you make the nv backup you tried flashing onto your faulty device?

    you wont find cm2spd with loader, you can still try searching for though
    try miracle box instead either write imei or backup from the other phone then write the backup to your phone

    Edit:- i have successfully write its imei back by selecting spd9832a cpu with 8830/10/6815/6531mode instead of BOOT MODE
    But problem remains same.

    I flashed its firmware again but nothing changes,still same condition.
    May be hardware fault because its screen has cracked edges.( like antenna will damaged)
    Edit:- I opened up the phone but no sign of damage to device

    imei, baseband everything is ok and even network strength is showing in phone info (code)not in about phone info.
    (*#*#4636#*#* to check) but no network in status bar
    I have noticed that its showing different service provider name each time when i dial code to check it. (You can see in pictures,i have a JIO network provider an its shows IDEA)

    I haven't remember anything mistakenly done by me in miraclebox .
