I posted in the wrong thread. Sorry.
I think that I have found a very important bug or something that I cannot fix and it's important to consider for all.
My slim 2504-B has actually a semibrick. I updated succesfully from 3.55 Kmeak no check, to Rogero 4.30, but then, and that was my mistake, I formatted the hard disk from the recovery.
Now the console asks for a firmware flash constantly, but I get a "data error" from the recovery for all the firmwares I put in a pendrive (even for the same 4.30 Rogero i already flashed before).
I suppose I need to reflash the 4.30Rogero, as I'm only missing the data of the HDD.
I'd ask to you, to put a little note saying people, NOT to format the HDD from the recovery, after being in this firmware, or they will get the same semibrick as I'm getting.
Is there anyway I can bypass this step? Please. There should be a way to fix this. I think I'm the first that has formatted the HDD and didn't know that I couldn't format it. sigh
Edit again: This is a very very important bug. Imagine that the HDD data gets corrupted and the console wants to format the HDD. If this happens to you, you'll have a semibrick, since you won't be able to reflash from the recovery.
Thanks a lot for your hard work for all of us, sorry for this engrish and the many posts
Thank you.
