Just caught this thread and figured I'd pop in. I can assure you that depending on the exact issues you had, it was infact related to the downgrade, For the people with weird issues like FC's, you got them because you downgraded and didnt wipe. A factory reset wouldve fixed stuff like that. Now, a broken wifi toggle I assure you is related to the kernel. Normally an older a mismatched kernel is no biggie (an example being running the ma6 kernel on the mb1 rom.) However LJ7(aka my odin oc) is android 4.1.1 and the mb1 update is 4.1.2. No surprise it caused issues. In all honesty the downgrade on top of not wiping in between Im surprised the phones even booted up. (hang on samsung glow;not brick). I will admit I should've labeled it better however i did not realize its popularity. With that said, when stuff like this goes down, CONTACT ME. I stand by the stuff i post and am more than happy to help u fix it.If you were one of the unfortunates who downgraded and put up with it til now, i commend you and apologize. The good news is a new version is almost up after some testing(waiting on feedback, my s3 is a loaner right now) Its only a 17mb download, takes about a minute to apply and isn't android version dependent as it doesn't require installing a whole system.
Heres a sneak peek as i have it completed for the note 2. Hopefully will be up today. If you flashed my old one and were downgraded I assure you your phone is not borked. Just having a few conflicts.Theres a few ways to fix it but here is what i recommend.
First
download this file and stick on desktop (its special just for this purpose)
Then
head here and download the file that matches yours phones storage capacity. Save it to your internal or external sd.
after that run the fix u put on desktop. It will take about 5 seconds after which your phone will auto boot to twrp. Apply my zip (no wipe needed) and your be fully updated in OUT OF THE BOX state. (with the exception of still having your data)
It may sound hard for the noobz out there but its a hella easy way to make sure your phone is how it should be. If help is needed Im almost always on google talk(username-billard412) and will have you good to go in about 5 mins. With all that said ill leave you with this:
If you ran my one click without problems i promise u can root just as easy, You are missing out. I also will have a one click root no counter increase out in the days to come so its only getting easier. But be on the look out for new stuff whatever your situation.
Thanks
