Error codes: 80029CCA & 8002F957 (PS3 jailbreaking from OFW to CFW 4.82.2)

Was möchten Sie tun?.

Es besteht keine Notwendigkeit für ein Downgrade, und es kann ohne die Verwendung des (inzwischen veralteten) 9,99-Downgraders durchgeführt werden.

(MOD EDIT)
There is no need to downgrade, and it can be done without using the (now obsolete) 9.99 downgrader

könnten sie mir das genauer beschreiben bekomme das nicht hin

(MOD EDIT)

If you could describe it to me in more detail, I can't figure it out

Before installing any CFW, check the min. installable FW version that your console can take. If you go lower than your console's FW factory limit, you will brick it.

Spoiler

Enable QA Flags in CFW Tools menu and then you may install a lowe CFW.

Again, I don't know what are you trying to do by downgrading.

The proper way of downgrading is to install CFW then use it to enable the QA flag, which will allow you to install any firmware version equal or greater than the one your console originally shipped with. Note that this is only possible on consoles that support CFW - there's no way of downgrading consoles that don't.
That being said - You have to install CFW to be able to do this, and at this point there's absolutely no need to downgrade. Evilnat 4.90 CFW has everything that every other CFW ever had.
The only reason to downgrade back to 3.55 is if you're going to be selling your console 2nd hand on a site that won't allow you to sell jailbroken consoles (e.g. eBay).

The QA flag basically turns your PS3 into a QA unit. These are used by testing teams in game companies to check beta builds for bugs. Having the QA flag set gives you access to a debug menu (nothing too interesting there, only the DEX debug menu is noteworthy) but more importantly - it allows you to downgrade your firmware, which is usually not possible. With the QA flag set you can downgrade the PS3 all the way down to the firmware it originally shipped with (you can use MinVerChk to determine what version that is).

How do I make the QA flag or is there a program dafüf my ps3 updat data of version 1. 00 or later can be installed on this system

On Evilnat 4.90 you can set the QA flag from the "★Custom Firmware Tools" menu (under the network tab). On older CFW versions you could use a homebrew tool like Habib QA Toggle. Mind that QA flagging is only possible on CFW.

If the minimum version is 1.00 it means you have a launch model (CECHA or CECHB) and you can install any firmware versions on them if you QA flag them. The only exceptions would be the beta 0.xx DEX firmware versions.
Please note that 1.00 itself cannot actually be installed because it was never released as a separate update. The lowest firmware available as a PS3UPDAT.PUP file is 1.02. The only way we could ever get our hands on 1.00 is if someone manages to get their hands on an unopened launch PS3 still on 1.00 and dump its firmware using a hardware flasher.
