Need MORE info. What was the Original firmware/ what firmware do you have right now? You said 4.2.2 but which one? MDB? MDL? or MF3?
MDB and MDL you can do a lot note with and use motochopper + Loki bootloader bypass. MF3 patched the exploit and can only use safestrap recovery.
Read some of the threads once you find which firmware you have and/or on right now. If your stock, then beware it will AUTO UPDATE you without your consent. So find out what you have and need to do quickly.
Thanks. Well, I had it rooted but it seems like I lost root when I did something, I don't remember but I think it's when I factory reset it to send it to be repaired. It still says custom when I turn restart it but I am not rooted. I'm not very knowledgeable at this, I just follow guides step by step. I used an old method to root, it was an automated tool, can't remember the name. Anyway, in my current custom, non-rooted state, sgould I do something first before using motochopper?
