PS3 Metldr news update and Guides
, this weekend Spanish PlayStation 3 developer DarkVolt
has made available dumpmetldr.bin via Elotrolado.net
which appears to be a dump of the new PS3 Metldr revision
found in PlayStation 3 CECH-2504 consoles (datecode 1b and above) followed by a PS3 Boot Loader SE Version 3.7.3 (lv0 segment) dump and more below.

To quote, roughly translated: Here I come to leave the metldr decryption: http://www.multiupload.com/YN4G8LJJK4
according fence can I go to publish a thing or two more.
Seeks the root key of geohot within the metldr dump I published aver if it sounds the flute.. I am the source and the base is an exploit..
Deneuve image but this time I am not clear. I have work I'll be realeasing more stuff. Saying this is not worthy... hehehe explanation:
We Have a decrypted metldr here, if you see it you will see a little Is An elf Without the normal header. It contains the root keys That geohot publish and a couple of 0x30 addead from 3.50 and ahead, and it STILL USES IT.
HAVING in the elf metldr we can put it the header and upload it in using it as anergistic unselfer for loaders! The metldr is still used in 3.74 (a debug already exists) and 3.73 retail too.
The difference of charge IS that before the metldr used to take the files from CoreOS and now it deliverer LV0 via ram em to us and close the access to the file BUT WE CAN IT DECRYPTED with the keys from the root metldr added if we have the file.
LV0 can be the decrypted if we fix the feat of math to support the bootldr and decrypts the metadata from the header from LV0 and decrypts this with the rest of the spaces with Their loaders.. Worthy is it not? hehe
Edit to add, if you compare a ISOLDR from 3.55 with the metldr you will realize that they are almost the same, I mean the isoldr contains the updates for the metldr (virtual of course)
That in and 3.60 + Also it IS inside of the LV0 so it every time can update the initial metldr boots with the new couple of the keys already have... uploading the metldr in anergistic http://pastie.org/private/2kijry6y7jwoiwsepqqcbq

With Metldr have almost total control of the console as we see in the picture above, however also shows that the bootldr is the only part of the PS3 outside the Metldr, but (and I say this in complete ignorance but using a logic low) and you have full access to the console should be much simpler to access bootldr in any case if this is true it would mean a breakthrough.

From by jon_17_
: The loads metldr ldr, ldr but these must be authenticated before a hash that contains internally metldr himself. metldr2 comes in certain consoles not downgrade (dataCode 1b and higher) are the most modern consoles today.
Metldr weighs 60KB (usually in some cases), the spu local store have 256KB. The loaders to load the LV0 be decrypted (always), lv1 (always) and lv2 (only in lpar_ps3). Decrypted the loaders themselves LV0, lv1 and lv2.
The lv2 to be deciphered in the lpar_ps3 saved in the spu local_store isolated the idstorage, this stores the hash idstorage of valid executables.
comes a Metldr LV2 Dumper for PS3 4.75 to 4.78 Retail Consoles by CMX
, who states the following:
Today is a special day. This marks an important release. You are now able to dump metldr from a simple pkg install, instead of using linux resources. That's right, thanks to CMX, this awesome bundle allows you to dump metldr without going through red ribbons and debians!
Flatz, for the original root key dumper source.
Joon and Mike, for the tests.
CMX (he made it all possible)
(The build script is ready to use, but i was too lazy to upload the modified pkg source in the first link
Finally, from haxxxen
to quote: Since it is easy to port it in a few minutes, i have made now a pkg from erk/met dumper for fws 4.21, 4.46, 4.65, 4.70, 4.75, 4.76, 4.78 (cex or dex)
Btw, you only need 5 symbols, so you can leave and remove the rest: toc, extend_kstack, copy_to_user, memset, memcpy. further it is only syscall table and those 2 gameos lpar thingies needed.
On another note, you should remove/comment new_poke install, since it can mess up with cobra mode. disabled, the dumpers work fine regardless of running cobra or not.
The lv1 patches can be done dynamically with search patterns and only htab and spe patch is needed, since the others are enabled by default (at least on rebug 4.21)
