Ok how downgrade from b513 to b331

Download transision pack and put to internal sdcard
Now turn off pone and go to flash firmware using 3 bottom
In 99% you have error but this its no bug and push reboot
Now it optimalize to 100 % and go to setting and check you firmware you must have MT7-L09C900B300
If you have now copy b331 to internal sdcard and do it that same as transision pack
this procedure delete you all setting and internal sdcard

I do it with ext sdcard and this setting to upgrade *#*#2846579#*#* and choose 4

Cheers and work now on b331

This is what I am gonna try. I am currently on B511. I had used the TWRP nandriod backup from a different thread to restore to B511. Now I will use another TWRP backup to get to B513, then I will flash stock recovery, and then use the official downgrade pack from to get to B300 first and then to B331. I am missing any necessary steps? Do you think this will work? I am waiting for your expert advice before starting..

yes you can but when you restore b513 twrp you must have eu oeminfo ---> https://mega.nz/#!UsZz1JJY!8y92sSzjRhalMhrq2dImF87iNneJ8HpXmh6KQ8Eo8LI
copy only custom.bin and check you region its eu. If its eu flash stock recovery do it wipe and check again region eu
If you have eu region you can try flash official downgrade pack ( but remember if you from others country like africa you must change oem on b331 to your region and flash stock room for your region )
