I'm really happy now, I've got this phone with problem since almost 2 years and I've found many problems since I've got an error death phone when tried to perform a wrong ROM MSM8939 my phone is MSM8916, then dead.. many search on net finally bring him to life with QFIL, lot a work to do it, and I move forward with error "/factory mount" and IMEI lost "null" I did give up to do anything on it until a 3 days ago, I was motivated and tirelessly for 3 days I kept trying, I've bring him to state of dead again purposeful to try to fix the problem somehow, tried for many hours/days, and finally I did!!!!! in this battle with fkn Asus I WON! ¬.¬'
Now doesn't matter what would happens to him, I'll solve! :laugh:

PS: If someone has the same error problem in the /factory and /persist partition mount or else,
1. Get twrp
2. Enter on twrp recovery (just enter, don't do nothing)
3. With adb on windows type: adb shell (will put you on phone in auto root mode)
4. Search for your partition with: ls -la /dev/block/platform/"name ur partition phone model"/by-name in my case mine its 7824900.sdhci example: ls -la /dev/block/platform/7824900.sdhci/by-name
5.After this you will find a partition name example my case: factory on /dev/block/mmcblk0p20 and persist on /dev/block/mmcblk0p39
6.After found you get this commands: mke2fs -c for the 2 partitions in my case it looks like this: mke2fs -c /dev/block/mmcblk0p20 and mke2fs -c /dev/block/mmcblk0p39 WARNING!! THIS CMD ON STEP 6 WILL FORMAT AND CLEAN THE PARTITION BLOCKso check if the number are correct for such partition.
7. This 2 cmds it will clean any error on the fault partition.
