here's for the psp 2000 ofw 5.51,
hope this help

If you still need them, I can give you any version for the PSP 2000 and OFW 5.03 for the PSP 3000.

If needed I have a hackable PSP2k, and can do for any firmware. Just let me know. Hope all testing is going good!
Good luck!

Here are the logs from PSP2K running 5.0x, 6.00, and 6.10.

IF you need anything else let me know.

PSP GO 6.10 log

I can test on any firmware.. I have a fully hackable 2k and a 1k (I know you don't need a 1k tester though). Currently I use 5.50 GEN-D4 (aka prometheus) but will upgrade/downgrade to any firmware you would like. Unless you don't need me. Just depends on how many testers you want.

Thanks for the offer!

I think we are done with testing on the 2000. My main focus right now is on 5.70 for any PSP. I wouldn't mind additional testers for this firmware.

Also, 6.00 or 6.10 on the GO and maybe an additional tester for 6.00/6.10 on the 3000.

I don't think there is 5.70 update & 6.00 Go update released to the general public.
So it will be really hard to find a non Go 5.70 & Go 6.00

5.70 also came with some 3000s, I know that there is no update for it. I just assumed that there would be a 6.00 update for the GO, too. But if not, then there is one less firmware to worry about.

Edit: Big thank you to everyone who helped us with this! The changes are in R96.

For completions sake I am still interested in the remaining tests.
