Just saying, this is not 100% accurate. The lowest firmware you can downgrade to isn't necessarily the stock firmware. For example, my stock 3.50 PS3 can go down to 3.40.
Best way to know the lowest firmware you can go to is to download the 1.02 PUP and try to flash it via XMB. Unless you have a launch model PS3 on which this model can be installed, you will get an error message telling you which is the lowest firmware you can downgrade to. Image proof :

Step 10 is my favorite.

Well of course m8. You have to be QA flagged to downgrade via XMB.

Please don't mess with QA flagging. Going by your posts your gonna end up messing your system up. Just wait a bit longer.

I know that i need to be QA flagged to downgrade.

What i asked is a little bit different: Do i need to be QA Flagged to get Pereb27 error with lowest firmware possible to my system? Since i got no sucess unflagged, i did the following:

Tried with 3.55 kmeaw, no QA (error: No applicable update data was found).
After with 3.55 OFW, no QA again, same error.

Now im QA flagged with otheros++ 3.55 CFW and still getting "No applicable update data was found" while trying start (just start, not finish) firmware flash of OFW 1.02 by XMB.

Any advices?

You have to install the Qa_Flag_Extra.pkg for it to downgrade. Then you will get the message he got above. Mine says that too, i got it down to 3.4 using the Move Game Disc which has the update on it. Use Recovery Menu to do it.

Just for check lowest version with the error you dont need to go to recovery, just set "System Update Debug" to ON and try the upgrade with 1.02 PUP.

Warning to others: Don't go straight to recovery menu because im not sure if it ll check your lowest version possbile before update, resulting in a brick if you went too low. Mine is 3.50 (factory 3.50 also).
