Flashing from SD 4.5 to 3.0
Howdy folks, a quick question that I have yet to find an answer to here on the forums. Am I able to flash directly from SD 4.5 to 3.0? Or do I have to go through the whole process or flashing stock, rooting, then flashing 3.0 to get where I want? I know that SD4.5 is based off 5.7.xxx and 3.0 is based on 5.6.xxx so I would assume so, but knowing me, I'll just take the easy route and flash directly if I don't read anything saying I can't.
If I do need to flash to stock and work from there, what is the recommended method of backing up apps and data? I have tried a few apps in the past when trying out different ROMs, but none restored the actual app when I went back to my favorite ROM, I always had to reinstall them from the market.
As always, any help is greatly appreciated.
