I installed rogero downgrader from the xmb. I checked my fw version and it shows that I am on 3.55 my cold boot shows rogero downgrader. I have tried to install 3.55 ofw from recovery, ive tried to install 4.70 from xmb, ive tried to install 4.75 ofw and each time I get the same error."data is corrupt". someone please help me. it says I need to install a firmware of 9.99 or higher. I have tried to install basically everything. I don't wanna have to flash it again. can someone please help me. no stupid questions like why didn't you just downgrade to 4.70, or have you tried all of them from recovery and xmb. I have tried that. so if someone who really knows what they are talking about could help me I would really appreciate it.
You need to downgrade to 3.55 OFW, then install 3.55 CFW. You should be able to update to another firmware after.
