Recovery Flasher 165 Beta Downgrade Original 6.35 auf 6.20 (oder beliebig).
For all to notice: This will only work up to Motherboard TA088-V2.
This new Version of the RF was made to protect the newer boards so you can not use the RF to install a custom firmware in HBL 620 or above and brick your psp. If your board is supported you go in HEN and use the RF to install the custom firmware without pandora.
Please remember the RF was designed to solve a semi brick from the recovery menu the ability to use it to install a custom firmware from xmb is only a bonus.
Sorry for disappoint all the owners of the newer boards. As you have noticed davee will release a downgrader soon wich will use the original sony upgrader so your psp can not be bricked if you use it.
Theoretically if some improvements will be made the RF could be used on the newer boards but Hellcat do not own so much PSP for testing/bricking.
