9g downgrade to 5.xx

[jas0n]

hi wololo members, this is my first post as i m new to this forum.

i m just wondering about my TA-095 Motherboard. its 9g module {PSP 3004} & it supports lower fw ie 6.20. i already downgraded it to 6.20. is there any way to downgrade it to 5.xx ?? afaik "NO" but why & how its not possible? i read somebody discovered that there is no difference between 4g & 9g module. so i just wanna know the exact reason behind this downgrade process.

pls anyone give me the correct information.

You can downgrade the 09g to the limit of the 04gs, cause the lower OFWs detect the 09g as a 04g, so the lowest possible would be 6.00 (5.70 if there would be an EBOOT.PBP for). But 6.00/6.10 does not offer any special stuff, so use 6.20 or 6.39/6.60 for CFW...


And if you want to say, 5.70 is supported, why not 5.00? Cause the 5.70 is like a pre-6.00 Firmware, like a 6.00 Beta firmware.
The 5.70 OFW is based on the 6.XX Kernel, so it is possible to downgrade to 5.70 but not to <5.55

Great info master!! i somewhat understood from u that 9g has a 4g capabillities..n i cannot go below 5.70 so its the limit..so wat tools i mean wat downgrader thingy ill be required? davee & some1? i m on 6.20. pls revert if this required anything different.

i am really missing my oldskool days... GEN & m33 the golden days i was not aware before purchasing this 9g headache

Jason about the best firmware to be on is 6.20 if you want it to be perm since it has the permanent bootloader. Your psp is a 3000 which means you cant use the oldschool cfw's such as gen and m33 cuz it would cause a brick and i wouldn't use the 6.39/6.60 ipl injection as it will cause a brick on any psp 3000. so the only way to have permanent cfw for a 3000 is 6.20 PRO or TN but i would use PRO as you are less likely to brick it when installing the perma patch.

i have a 9g motherboard but when i got my console it came with fw 6.30 so is it worth trying to get to 6.20??????
my fw is 6.39 pro-b10

You can downgrade your PSP 3000 09g with a TA-095v1 motherboard to 6.20, but you CANT flash your PSP 3000 09g TA-95v2 motherboard to 6.20.
The 6.20 has a standby bug for those 6.20 09g PSPs. I think it does not worth it, just use 6.60 PRO-B10fix or 6.60 LME-1.6 with LightSpeed.
