[GUIDE] Downgrade to MM after Sideload Nougat [encrypted/decrypted Data]

[Mina Mngawy]

First of all every step you'll make is at your own risk
sorry for my bad english

requirements :
1. unlocked bootloader is a must
2. full flash of latest 3.2.8 ROM on your computer you can find it here Mega Google Drive
3. stock recovery on your computer " download from official website "

Steps : ( make sure that u backed up all of your data )
1. flash modified twrp recovery via fastboot for Nougat from here
2. reboot in twrp recovery , it will ask for password to decrypted your data just cancel or skip and allow modifications on system
3. go to Mount and mount System
4. go to Wipe > Advanced wipe > select system > Repair or Change File System > Change File System > EXT4
5. go back to wipe and select Format Data
6. again to Advanced wipe > select everything there except USB-OTG
7. reboot to recovery again
8. connect your device to computer and copy the full 3.2.8 ROM to your device
9. go to Install > select the 3.2.8 ROM file
10. after it's done reboot to bootloader
11. flash stock recovery via cmd ( fastboot flash recovery *FILENAME*.img )

I'm tempted to try the new Nougat CB, but I need my phone to be reliable. So I'm wondering why people revert back to MM. Anyone care to share why they prefer the older MM?

The best one is open beta 8 Nougat
But the stable one is official 3.2.8

Well most of the users like to have Xposed installed and for now is not posible on Nougat so most of us prefer to go back to have Xposed
