In a recent previous thread i talked about how in china (im on a long summer vacation) they changed my official 3.40 psp to 3.10OEA'R+. they took my psp to the back spent 2-3 hours on it and when i got it back it was 3.10OEA'R+. This was in the beginning of June 2007.
It looks exactally like 3.40OE-A. i have another one i bought on ebay, and i also upgraded the 3.10OEA'R+ one to 3.40OE-A so thats how i know they look the same. What looks the same of course is the recovery menu with all the same options.
What i think is that China hacked the Dark Alex's custom firmware and now have the ability to create their own firmware. Just guessing but they probably learned the code by looking at Dark's.
Here in Custom PSP's are big business, im 90% sure they can create custom firmware themselves.
I dont mean to create some crazy rumor, this is just a theory and im sure its totally rational.
If they did this would be good news to the community, if China is willing to cooperate with the community and release us the updates should they have new custom firmware. They may not release it as it is big business their. They sell their custom PSPs openly in the store and profit off "fixing" other peoples official firmware PSPs.
