Appreciate the update and reply, more so as this is unpaid and in spare time. Good luck.Still working on it @MudkipDan . The system is slightly harder to penetrate than I initially expected but I do have an exploit I been working on that should be able to give me an entry point. Once I have something concrete to show the community I'll make an announcement.
Hello @DreckSoft, yes you are correct on both accounts. the firmware is encrypted and it is the same for all of those models. I already have the latest version of it but in any case thank you for your offer. I'm dumping the roms by flashing them and then dumping the NAND chip. It comes out like a "bit salad" but I'm writing some code to try and make it work.I think I do have a firmware for the 820 (if I can find it). However, the firmware should be the same for 420/424/820/924/9000 and 9004.
You will need the encryption key and method from the player. No chance by just comparing the files (I tried). Only the first few bytes (header?) are identical.
libc is LGPL, so Panasonic is required to release the source. You could contact Panasonic and request the source to all open source parts. If they won't release it, contact EFF.
An unencrypted dump of the firmware could also be interesting even if there is no way (yet) to put it back into the player without directly flashing the NAND. There are still a few issues that haven't been resolved:
- PUO off for BD only works partially. There are still titles that can't be skipped and jumping directly to the main menu doesn't work.
- The USB / network player has restrictions. It will not play DTS-HD, Dolby TrueHD or even E-AC3.
I think I had one or two more which I currently can't remember.
28050000-28128fff: r-xp /lib/libc-2.20-2014.11.so
28138000-28139fff: r--p /lib/libc-2.20-2014.11.so
2813a000-2813bfff: rw-p /lib/libc-2.20-2014.11.so

That sounds awesome. It is really a shame, the guy didn't release his work at least before he took down the page. There are rumors he had access to the source code. That could have been the base for a even more enhanced firmware but money talks. There was a time when modified firmwares were free for all
What's all the hardware you're using?
On the left it is likely an adjustable power supply. The LA1010 USB logic analyzer is obvious but the rest?
Yes, I've heard of some stories like that, I'm hoping I can make it work as well, getting close.Hopefully u can make a working firmware.
I Always wonder what the deal with the guy who ran that site was. he was like the soup nazi from Seinfeld if u didn't follow his order process to the T he would cut u off.
He banned me permanently because i had bought the firmware for a player and the player failed after 2 years but i had best buys warranty on it so best buy exchanged it for a newer model. he refused to honour the discount for repeat buyers even though i had bought several firmware off him. i wasn't rude in anyway just asked nicely if he could still provide me the discount and he banned me lol.
i heard of many people getting banned for doing far less.
I bought my player with the intention of installing the RegionFreedom firmware in it. However by the time I got my player, the guy running RegionFreedom was basically MIA and no longer contacting people or responding.
I’m still really wanting to make my player region free.
Has anybody figured out exactly what the RattleByte hardware mod does? If I install it will I be locked out of this threads potential firmware?
Been looking into RegionFreedom and found they no longer exist?
From what I can gather this is about building a new firmware/update to allow region free for all and it's a work in progress?
If it is, I'll follow this thread
You are correct about the check during the update process. I also tried to flash it on another player and simply nothing happens.
Btw: Have you looked at the Panasonic Firmware Hacks for the cameras? Maybe they used a similar encryption there.
