PS3 Firmware 3.55 Downgrade Released Submitted by; January 13, 2011 Backed by mathieulh's advice, solidpsycho does a solid for all those wanting to return to firmware 3.41; I'm sure you have your reasons. You'll need to re-equip your jailbreak/downgrade device for this one.

Downgrade at your own risk. You may downgrade your PS3 to a brick if you're not careful. Several reports indicate success (mostly Fat models); others have reported bricks (more Slim models; 3.50/3.55 out-the-box). Nasyid Alif Ba Ta Malaysia. My boy,, he successfully downgraded his Slim (not 3.50 out-the-box). You're also at risk of losing Blu-ray movie playback. Backup your PS3 saves and other HDD data.

Again, proceed at your own risk. I like how it says that bricking the PS3 is possible, especially in the 'Slim' models that were OFW 3.50 and 3.55 out of the box, then people are saying 'HELP PLZ i just installed this now all i get is a yellow flashing light before my ps3 shuts down, can this be fixed ', obviously these kind of people have no idea about how this stuff works, but are so desperate to play pirated games.

I was unlucky enough to replace my phat ps3 with a slim with 3.50 out of the box, and would love to downgrade, but the chance of bricking it just aint worth it, would rather spend £300 on games:) but for all the peeps that gets it to work, gratz. Worked perfectly on my ps3 slim 3.55 with ti-84 silver just go to download the current version transfer it with ti connect then start the app press 5 and change the setting so emulate jig says yes save it then press 1 to start jailbreak after that ur ps3 sud turn off now plug in ur usb drive that has to modified pup and lv2.self 1 turn on ur ps3 and nothing sud be on the screen it will be blank for like 10 minutes then take out ur usb and put the lv2. Self 2 on there and plug it back into ur ps3 and again nothing sud be on ur screen and it will turn off in like a minute now take everything out and turn ur ps3 on as normal and it sud load up like u just bought it brand new and there u go all do make sure to put a payload on it after the downgrade and make sure to turn emulate jig off after downgrade. NO DONT TAKE OUT THE USB WHEN THE lIGHT IS BlINKING.

Only take it out when the ps3 has shut it self off. U will brick your console if you remove anything while it is still powered on. 1)get the software from brandon wilson for the ti 84 2) transfer the software to ur calculator using TI Connect from ti instruments website. 3) plug it in the ps3's usb slot via mini usb cable 4)go in the app on the calculater and toggle the 'Emulate Jig' to 'yes' and press save.

5) turn on ps3, it will turn on and show factory / service mode, turn off the ps3 from the controller. 6) with a usb flash drive formated to FAT32 (you can format it in 'my computer' by right clicking and clicking format.) put the FIle 1 and the modified PUP file on it only. 7) remove the calculator and plug in the flash drive on the usb at the very top (closest to your bluray drive) turn on the ps3, it will do its thing and turn off. 8)when its off, u remove the usb drive and take it to your computer and delete EVERYTHING off the flash drive and put the Self file#2 on it BY ITS SElf(so there is nothing on the flash drive except the file#2) 9)plug it back into the ps3 in the same place you did before and power on. Let it do its thing( DO NOT GO BY HOW MANY TIMES IT BlINKS, IT WIll POWER OFF WHEN ITS DONE) 10) when its powered off, take the usb out and you have succefully downgraded OR converted your kiosk ps3 to retail.

NOTE: if your ps3's NAND is 256mb then you will probably loose your Bluray Disk Playback. Search up Drl generator to find a fix. I upgraded to the 3.55 fm a when it was released. I than used the Geohot fm and it worked good but it didn't allow for the backup managers to work. About an hour later they released a new version that would but I would have to reinstall the official 3.55 again. Here's where my problem came.
