Guys don't judge me hard. I screwed up.

[shi may]

So long, story short i had to reinstall a new om on my Samsung Galaxy S 4 (Cricket) (SCH-R970C), so my choice fell on a stock android rom (4.2.2), and now i want to go back to the touchwiz i had before(4.4.2), but i cant. I have downloaded the firmware but it aborts the installation l. Also it looks like my phone is gt-i9505g now. I wish i could get a new phone but i won't be getting new one soon. So i really wish i could get this one working normally again. Any advice helps.
