Sorry guys, I'm new to Android and all of this and i'm in a foreign country so i don't know what to do.
I have a B506 with KitKat, but i want to downgrade to B125, can anyone help me?
I know this question has probably been asked before, but i couldn't find it and i really don't know how to do this, so sorry for being a noob.

Flash through adb stock recovery. Put update.app B125 in dload folder on sdcard and press volume up + volume down + power button until the phone starts updating.

This will not help.

For downgrade from B506 to B125 you will need a middle step. First flash that: https://mega.co.nz/#!9oEHUTiR!uVKEq6...QZ5yrnedx4rug4 via stock recovery, after that you will able to flash B125.

Not true. LOL The middle step it's a EMUI ZIP. That's so crazy. Man, don't make people follow your nonsense advice.

alex.79 is right, you can't downgrade directly from B506. That middle step is needed. So the nonsense advice is yours.

My frend don't give advice on things you are not quite clear for you. In this case nonsense advice is yours.

No such step needed, you just try to make downloads with that link.

Tested without that step and all went well.

I've downgraded twice but never used that file. What is true (if i remember well) every time, at the firs boot, phone got stuck at logo. Installed the same firmware again and worked. At the second install, i think the script saw that something was not in place and did a factory reset. Maybe a factory reset should be done before downgrading.

Actually, this method works. I did not need the middle step. Just put the download update.app in the sdCard root AND in the dload folder, and then do a stock recovery boot.

In fact, I used the systems local update and got B125 no problem at all.
