So recently a tutorial came out to jailbreak 4.82 OFWs & I had a spare OFW laying around so I thought I'd give it a go and give it to my brother since he's always been fascinated by it when he saw me do it over the years. the BD Drive is broken & so I installed an NOBD firmware, fixing this issue. But I then realised it wasn't a REX firmware, so I couldn't transition to DEX. I then ended up downgrading to 3.55 ROGERO following a tutorial, so I didn't mess up due to lack of memory on upgrading/downgrading. I then tried to go to 4.70 REX COBRA NOBD, but I couldnt. I didn't take it as much & redownloaded the firmware. But I had got the error again. So long story short I tried just about all basic firmwares and none work. I can't toggle qa due to the bd drive being broken, and the firmware I'm on doesn't patch NOBD. Therefore meaning I have no debug settings either. I'm lost for ideas here & really don't wanna waste money on another cfw if I can maybe fix this one. Any help is hugely appreciated.
