    Yes you can, the downgrade works for 3.6x, 3.7x, 4.00 & 4.11 - tried and tested many times

    How long does it take to downgrade to 3.55 from 4.11?

    Depends how quick you are at soldering really, unless you use the solderless clips. Most of the time is spent waiting for the NANDs to read/write. If you know how to use Hexeditor then its pretty straight forward

    Or Better still... forgot about this tool - Venix Downgrade GUI

    This app patches both NOR & NAND images ready for downgrading. Saves the hassle of hexing the patches!

    Mushy409 Can the single/dual NANDs on the fat ps3 motherboard be replaced? If so, will the ps3 be operational? I would think so since the things are brand new and would need to be flashed with any firmware since they're empty, right? Just wondering.

    hello all... I have 3 bad blocks after nand0 dump using infectus double nand programmer v1.41. Tried 6x with the same results. No issues with nand1. When I use the infectus programmer, i don't receive any errors for both nands. I checked the wiring many times and the solder points are good. Before I proceed, could someone provide some insight. (wanikoko v1 brick)

    Below is the error log report for nand 0. If needed, i will upload the files for further review...

    excellent guide mushy409.. but I have a question that you probably know the answer I don't think that no one have tried this but i cannot read anything anywhere that maybe can lead us to downgrade easily a 4.21 console without a flasher, so here my question...

    Now that we have the 3.60 keys is not possible to sign jaicrab LV2DIAG.SELF for work also on 3.60 and up to 4.21 firmware for exit from factory service mode ? if this work maybe we can downgrade easily no ?
