SGH-1527 Is Downgrade OS from 4.4.2 to 4.2.2 possible? - GSM-Forum

searched this section for downgrade didn't find what I was looking for

To make a long story short, I bricked my Mega it was running firmware version 4.2.2. When I took it to the cell repair store they put 4.4.2 in it. Now I cant use my SVOX voice engine because it force closes on this version. Also a lot of other apps don't run correctly on it.

Now they say that a downgrade is not possible. I thought flashing was an overwrite? When I redo my windows pc I would format the drive and use norton ghost to load an image. I thought that's what flashing was?

Can it be fixed back to 4.2.2

I didn't say "not possible"...
I said to read up on your model and see if it could be downgraded without hard bricking the device....

Many Samsung phones cannot be firmware downgraded... I don't know all the models that allow downgrading... That's why you have to research.
