Fix the DADADADA error with Recovery Flasher

DANGER

This guide is for PSP 1000 and 2000 (except 2000 with a ta-088v3 motherboard) ONLY! Ta-088v3 2000, PSP 3000, street and GO will be bricked!

Older Custom Firmware like the 3.40 OE or the 3.52 M33 had a protection to avoid updating to Official Firmware and lose Custom Firmare. This protection is giving you the DADADADA error. If you are running the 1.50 firmware this guide will allow you to run the tools necessary to fix IDStorage issues (error DRNFFFFFxx).

We will fix it by updating to the 5.00 M33 Custom Firmware which disable this protection and allow you to update to 6.61 Official firmware.

Get started

Download and install the Old Custom Firmware Update Pack

Download the pack here:

For old Custom Firmware: Google Drive

For 1.50 Official Firmware: Google Drive

Place the pspIdent, RECOVERY, KeyCleaner and UPDATE folders in the GAME folder of the memory stick.

X:/PSP/GAME/

Place the 500.PBP file at the root of the memory stick.

TIP

What we call root is the "base" of the memory stick, it should look like this:
X:/500.PBP

Run Recovery Flasher to install 5.00 M33-6

Run Recovery Flasher.

Set the Target FW to 5.00.

Select Install CFW.

You will get prompted to keep or reset your settings. Reset them.

Wait while Recovery Flasher install the 5.00 M33 Custom Firmware.

Once the console has rebooted, try to update to the 6.61 Official Firmware.
