BD-P1600A/EDC update problem/decrypt FW and flash

[fauxkalel]

I have problem with updating process in above BR, there is unfortunately FW v1.00... When i try to update from USB there is verification process but after some time of veryfication only thing coming next is black screen/signal off? There is no question about proceed before that. Direct Internet update wont connect to update servers (probably this directories on server not even exist anymore or network card dont work on my device ( but ping to gateway is ok). How i can force update? Tried modified by me FW for other region variants, but same end. Region for FW is europe XEF (latest and only downloadable in internet is BEv2.21_120515_BDP1600_XEF).
I already tried to find something and done some TTL "dd" from mtd0 to mtd10 to usb flashdrive and some:

Code: Select all

# nanddump /dev/mtd1  -f  kernel.gz
Block size 16384, page size 512, OOB size 16
Dumping data starting at 0x00000000 and ending at 0x00500000...
# nanddump /dev/mtd2  -f  rootfs.bin
Block size 16384, page size 512, OOB size 16
Dumping data starting at 0x00000000 and ending at 0x02800000...
# nanddump /dev/mtd0  -f  cfe.bin
Block size 16384, page size 512, OOB size 16

List of all partitions:

Code: Select all

# cat /proc/mtd
dev:    size   erasesize  name
mtd0: 00180000 00004000 "cfe"
mtd1: 00500000 00004000 "kernel"
mtd2: 02800000 00004000 "rootfs"
mtd3: 007fc000 00004000 "pstor"
mtd4: 00140000 00004000 "splash"
mtd5: 00020000 00004000 "drmregion"
mtd6: 000c0000 00004000 "rawnvr"
mtd7: 00004000 00004000 "macadr"
mtd8: 00020000 00004000 "nvram"
mtd9: 00640000 00004000 "swap"
mtd10: 04000000 00004000 "all"

Please someone help me extract images from RUF or something to maybe update partitions manually, then reflash in normall way?
If needed, then i can try to get some decrypt key for RUF, but need tutorial how to do this in this BR.

I am using next post because i probably already catch error during update, so i want to separate this things:

Code: Select all

,,,,,,,,,,,,file name : /mnt/hd/squashfs-97601.img
   [4294795.038000] CPU 0 Unable to handle kernel paging request at virtual address fffd5000, epc == 8001856c, ra == 80019210

Maybe this will help in decrypt FW:

3rd post, but without any help from anyone, this will separate parts from problem, diagnose to solve problem:

When finally i have found FW in version 2.02 from US variant, edited it and successfully flashed (probably just little smaller squashfs partition), then edited europe FW to flash from US to the latest FW, and all done!
Now BD play even latest BR discs for now and mkv 1080p with separate subtitle files from ntfs USB flashdrive.

Still want to decrypt and repack RUF currently for mods, so please anybody help to accomplish this.

I posting dumps in diffrent ways and cross-modded FW variants to flash trough older FW release:

FYI, Mega links without key are useless if you don't provide key
