XA2 Ultra Unlocked > Sailfish OS > NO MORE REVERTING TO ANDROID POSSIBLE???

Is there anyone out there who has walked the road that I am walking right now and has reached the end?

 

1. Read about SailFish OS ( SFOS 3.1 by now) and got interested.Grinning Face

2. Read about Sony XA2 Ultra Dual SIM ( H4233 / 1312-4773) being compatible with SFOSGrinning Face with smiling Eyes

3. Bought a H4233Smiling Face with Heart-eyes

4. Unlocked the bootloader ( with the nice help of Official Sony site)Smiling Face with Heart-eyesSmiling Face with Heart-eyes

5. Flashed SFOS ( Very Easy procedure so far) Grinning FaceGrinning Face with smiling EyesSmiling Face with Heart-eyes

6. Tried SFOS for a while...but then realised SFOS is NOT for me, NOT to be recommended for anyone wanting to use  a flawlessly working OS ( Not even close)Unamused Face

7. Thinking I want to revert back to good old AndroidRelieved Face

8. Trying out ALL possible ways of trying to revert:

8a. EMMA ( standard user version?) DOES not work for Unlocked devicesDisappointed Face

8b. Sony Flashtool ( EMMA for developers?): Does start but gives this: Angry Face

8c. Flashtool by Androxygen ( in combination with XPERIFIRM):

tried all kinds of versions....

  1. First of, I cannot Find the EXACT version of my ROM...WHY?   My BOX says:20190802_123338[1].jpg

BUT Sony FlashTool Says:

But these are the Files to download for the H4233:

I don't know if that is the reason for all my subsequent issues with FlashTool by Androxygen, but I cannot flash my XA2 ultra with this tool

Nor Can I re-lock it with this tool because of:

Which brings me to the closed Loop I am in right now:Dizzy Face

8d. Sony Companion: Does not work for Unlocked devices:

Does anyone recognise my issues?

Is there ANYONE out there, that can help me revert back to good old ANDROID?

 

 

with regards,

Haldun

This is just guessing, but you could try just putting on AOSP first. Not 100% sure how and if that will work out, but at least you could try that. Googles Android Tools (especially fastboot) are not very pickiy, the just flash whatever you tell it to flash.

 

An Guide on how to build AOSP can be found here: https://developer.sony.com/develop/open-devices/guides/aosp-build-instructions

 

I am using AOSP on my Xperia XZ since a while and beside some minor bugs, i am very happy with that.

 

But you can also just try again EMMA to re-flash it with the official Sony Image afterwards

Hi,

The H4233 device is an localized model and is not supported by the Emma tools (it supports only Global devices)

The bootloader can not be locked
