    I Had the 5.00 m33-6 update successfully, but when i tried to upgrade it to the 5.50 GEN-a, i got to about 90% of the update and it said there was an error, couldn’t switch off normally so i took out the battery and put it back. Unfortunately it never came back on, the green light stays on for a minute and then it goes off, what do i do, someone please help me. ASAP.

    Sounds like you bricked it. You’re going to need a Pandora battery to fix it.

      No you can’t. If you’re on Chickhen, your PSP isn’t hackable.

      Yep. Especially if you want to upgrade to 5.50 GEN-D3. Even if you don’t plan on upgrading, it’s still recommended to install the GEN B-2 patch.

    I installed 5.50 GEN-B2 but it is still GEN-B (full) in the system version. Is it really like that?

      Yep. I guess the GEN TEAM forgot to update the version number with GEN-B2 but rest assured that it was successfully installed.

    i’m trying to upgrade my psp from 5.50 GEN B to GEN-B2, when i try to update it, it said the data is corrupted. Should upgrade to GEN C then to GEN D?

    • sylv3rblade on 25 Jan 10 at 00:20:42 said:

      No, you don’t need GEN-C to upgrade to GEN-D. The files you’ve downloaded are probably corrupted, try downloading it again.
