Untill what Firmware can we downgrade ?
Untill what Firmware can we downgrade ? –
I was asking myself untill which fw i could go back with my 20GB CECHB PS3...
So i thought maybe we could make a little list so that users don't try to downgrade to a version that never made it to their console...
Help me doing that list and correct me if you see anything wrong in it.
Thank you !
First Firmwares on different PS3 models
- CECHA > 1.00 JAP,1.02 US? (8/2006-8/2007)
- CECHA00 JAP 60GB > 2.00
- CECHB > 1.10 ? (8/2006-4/2007)
- CECHC > 1.51 ? (8/2006-8/2007)
- CECHE > 1.80 ? (8/2007)
- CECHG > 1.92 ? (10/2007)
- CECHH > 1.92 ? (10/2007)

- CECHK > 2.35 ? (8/2008)
- CECHL > 2.35 ? (8/2008)

Reason: UPDATED !
Or if anyones knows for sure that some models can downgrade to any firmware
that could be useful as well...
As for the Slims starting by CECH-20, i can safely say that there was no otheros
on them so the FW is prolly higher or equal to 3.21
(to admins, mods: maybe that thread should be in General Jailbreak Discussion ? )
First Slims - 2.76

3.15 was released a long time after first Slims were on the market.
Oh thanks for pointing that out...

Can anyone else confirm this and for others please ?
i made an up & downgrade test with my japanese 60gb CECHA00 in this order
3.41 - 1.10 - 1.31 - 1.60 - 2.53 - 1.81 - 2.10 -1.82 -1.92 - 2.01 - 1.93 - 2.00 - 3.15
i can confirm for sure that the tested CECHA00 was downgradable up to fw 2.00.
all attempts to make a downgrade from a firmware under 2.00 arenīt working on my console.
I can confirm this one:
CECH-25 > 3.40 (7/2010), as i have it from the first batch.
Confirmation for 2.76 Slims http://boardsus.playstation.com/t5/P...6/m-p/43381568
And about the 2.76, it was factory installed so it could be different form a downloadable update. First firmware that Slims could update to was 2.80, so I guess that would work for downgrade. I can't backup my Slim's HDD so I can't test.
