Hi all,
My phone hadn't received the official Lollipop update until 2 days ago. I had tried several cooked/customed ROMs before, so when I use the *#2663# code (after installing stock Lollipop) it appears like this:
Phone's Touch key FW version: 0x09
Part's Touch key FW version: 0x10 <= This is the problem, my [Back] key doesn't work at all, while when I touch the [Menu] key on the left side it opens the S Finder just as I am holding it. I suspect one of the cooked ROMs caused this problem.
When I tried reverting it back to KitKat (either stock or cooked), it became this:
Phone's Touch key FW version: 0x08 <= Changed to 0x08
Part's Touch key FW version: 0x10 <= It's still the same but the softkeys worked fine.
Another person's phone (same model), which works fine, has this instead:
Phone's Touch key FW version: 0x09
Part's Touch key FW version: 0x09 <= Same version as Phone's FW
I tried looking up for solutions from other XDA posts but they only instruct people to enter the *#2663# code and update Part's Touch key FW version to match with Phone's Touch key FW version because the latter was lower, but in my case it is higher than the former so I gets an error everytime I try to do that ("IC's F/W is higher than Bin's F/W").
So I am asking for a solution of how to downgrade Part's Touch key FW version, beside the method of flashing the original ROM that came out with the phone (I tried that... no luck :crying: ). Hope that someone can help. Thank you very much :laugh:
