A number of weeks back among some other perform-arounds we noted on a venture aiming to repair PlayStation 3 Blu-ray drives for those who downgraded their console, and today the group has launched DRLTools DRLGen v0.90 suite presenting an effortless to use PS3 Blu-ray playback repair.
From the integrated ReadMe file:
Our quest to restore BD playback for these PS3s that misplaced it following downgrading continues. Regrettably our project suffered a critical setback very last week when 1 of our discoveries was prematurely leaked: A probably unsafe and incomplete technique to restore BD playback was disclosed by an consideration-looking for personal. It should be noted that the fix in question is only a “band-aid” option to the issue.
There is a extremely true chance of potential drive revocation resulting in Completely damaged playback! Even so, to make utilizing it safer for these who want to use it, we have designed this collection of DRL Instruments. In the meantime we are continuing to perform on a everlasting and straightforward remedy for all PS3s.
The instruments in the suite are:
- DRLbackup v0.90 (PS3 pkg utilised to backup DRL1 / DRL2 files to a USB drive)
- DRLgen v0.90 (Windows .internet 2. application to derive DRL1 / DRL2 files from an MKB_RO.inf file)
- DRLcopy v0.90 (PS3 pkg to restore previously backed-up DRL1 / DRL2 files or to copy derived DRL1 / DRL2 files from DRLgen)
HOW IT Will work
Every Blu-Ray film consists of a Media Critical Block (MKB) as component of its copy protection scheme. Newer motion pictures function larger MKBs the most recent a single is MKB v20. Addtionally, every BD film has a special encrypted title crucial. The two are saved within the AACS/MKB_RO.inf file of each and every disc.
Fixing BD playback involves specific expertise of which was the first instance of the highest MKB played so far. DRLgen can be utilized to identify the Blu-Ray movie with the greatest MKB, and then develop substitute DRL1/2 files for your PS3 which then restore BD playback.
one. A suggests to entry Blu-Ray title discs to collect the AACS/MKB_RO.inf file, a Blu-Ray drive in a Mac / Windows Personal computer would make the procedure simplest. Alternatively, SAK v1. can be set up as an OtherOS on the PS3 with firmware 3.fifteen or reduce to accomplish this job.
2. Explicit expertise of Every blu-ray title the blu-ray drive has played and the MKB versions of people discs. WARNING: Whilst you can safely check out each BD’s MKB with DRLgen, you really should restrict the range of attempts of putting in DRLs on the PS3, as the complete particulars of the AACS “traitor tracking system” are not well recognized.
3. A FAT32 USB storage gadget to retailer and retrieve MKB_RO.inf and DRL files.
Complete guidelines are accessible on the Project #PS3bluray wiki http://ps3bluray.information/?title=DRLtools with an excerpt below:
“If you downgraded with no a DRL backup, or tried the earlier (not absolutely appropriate) leak then use DRLgen on a Windows Method with a Bluray reader (or Linux on the PS3) to retrieve the MKB_RO.inf from /AACS from the greatest MKB version blu-ray you played in your PS3.
Make sure you Notice: If you do not know which Bluray is made up of the highest model of MKB, you can use DRLgen numerous occasions to watch MKB_RO.inf files in your assortment to come across the one particular Blu-ray that has the greatest MKB version. You can do this by “Creating DRLs” many instances, altering the disk each time. Be positive to hold cautious data of what discs are what version.
When you have obtained the bluray that has the greatest MKB version that has been played by your PS3 prior to Downgrading. Spot it into your BD in your Pc, pick the DRL Help save site in the choices of DRLgen that is your USB flash/pen drive, and “Create DRL”. Observe: If you are making use of PS3 linux, or have copied the DRL from yet another technique with a BD drive you may possibly select the place exactly where you have saved the MKB_RO.inf rather of navigating to the BD.)
At this stage all paths appear jointly, and there should be a folder on the root of the USB Flash/pen drive with a folder referred to as ‘PS3bluray’ that is made up of just two files dev_flash3_DRL1.bin and dev_flash3_DRL2.bin.
Put the USB drive into a running and Jailbroken PS3 and run DRLcopy on the PS3. This will produce 2 backup files dev_flash3_DRL1.bin.bak and dev_flash3_DRL2.bin.bak. These are backups of your PS3′s DRL before copying the ones from USB. You need to help save them some wherever for protected keeping incase you ever want to restore them, or you have chosen the wrong edition of a MKB_RO.inf.
As soon as this completes, exit jailbreak on the PS3 and attempt to play the Bluray as regular. This really should now let you to play blurays.”
ABOUT THE Equipment
DRLgen is a new and SAFER utility that utilizes the MKB_RO.inf from a Blu-Ray disc to derive accurately formatted DRL1 and DRL2 files effortlessly every single time. No challenging hex editing or byte-counting is concerned.
It is important to notice that DRLgen uses the AACS’ specification for the MKB format and does not merely assume DRL data begin at a certain place and are of a certain duration. The formerly leaked data makes all these assumptions and is flat out INCORRECT in numerous circumstances nowadays, and is NOT foreseeable future proof and could lead to permanently damaged playback.
DRLbackup, formerly released, has been up to date to operate in cooperation with the other two instruments. As a very best practice, a backup of the DRL1 / DRL2 files ought to be produced prior to any program downgrade. Use in conjunction with DRLcopy for a totally recreatable process to downgrade your Big NAND PS3 and restore Blu-Ray playback in the long term.
Notice: The place of saved files has altered, consumers of the older edition of the device ought to put their saved DRL files into a ‘PS3bluray’ folder in the root of the USB storage gadget for compatability with the new DRLcopy instrument.
DRLcopy is a new PS3 device that utilizes the output of the new version of DRLbackup (or effectively situated DRL backups from the prior edition) and/or the derived DRL files from DRLgen to restore your blu-ray performance following a firmware downgrade.
