Hi Everyone,
I just updated my old blog which is http://fatirsiddiqui.spaces.live.com to http://fatirs.spaces.live.com
Here, I continue posting up new stories regarding new software, hardware, gadgets & music …
So keep me updated with your Music Requests, PC problems, comments and feedback, I will look forward to provide free and easy solutions or you can stay interactive with my new tech group which is http://geekscorner.groups.live.com/ …

LG Electronics, a leading maker of consumer electronics, has reportedly announced its second-generation hybrid optical disk drives for personal computers (PCs). The novelties can read all four disk formats currently sold, including Blu-ray discs (BDs), CDs, DVDs and HD DVDs, which brings quite some value to end-users wishing to watch high-definition movies on their PCs.
The new drives in the Super Multi Blue family of LG are LG GGW-H20LI and LG GGC-H20LI. The former can read and record CDs, DVDs and BDs as well as read HD DVDs, whereas the latter supports recording on CDs and DVDs and reading all four types of discs. Both feature LightScribe technology that can create labels on optical discs.
It is interesting to note that LG GGW-H20LI and LG GGC-H20LI will cost $499 and $399, respectively, which is much closer to mainstream price-points at which customers will really start to get the novelties. Earlier Blu-ray disc burners could retail for about $1000, which did not allow them to become really popular. Meanwhile, the most affordable HD DVD drives for PCs from Toshiba cost approximately $250 in the U.S

>> Hackers on the XBH forums managed to change DVD key and Game Region Code in the Xbox 360 'Key Vault' (that stores on flashchip: console certificate(s), per-box private keys, DVD key, however NOT any code-related encryption keys).
However you should know the 'Key Vault' is encrypted with the per-xbox360 'CPU key', so that means this hack is only possible on Hypervisor exploitable Xbox360s (kernel 4532 and 4548) for now. You will of course also have to read/flash the Xbox360 flashchip (by desoldering it and read/flash it with programmer or for example use the versatile Infectus dev chip)
I successfully changed the DVD key and region code of a 360. So it's all confirmed.
As for landmarks and interweb fame. All I did towards this was to reverse the plaintext KV signature to figure out how to modify and resign the KV contents. And even this work was built on the efforts of other hackers. For example, I didn't locate the region code in the KV and a lot of the SHA1 and RC4 encryption code was reversed and documented by others way before I started looking at it. *If* the region code tests are successful, then the following people contributed *much more* to this achievement than me.Takires, TheSpecialist, Robinsod, tmbinc.
The following assumes you have the correct 1BL key and CPU key set in the flashtool.
1. Dump the NAND from the US 360 (528-bytes-per-page)
2. Open in the latest flashtool (v0.8) and click [extract]
3. Edit extracted KV.bin and change 16-bits at offset 0xB8 from 0x00FF to 0x02FE
4. Open in flashtool and click [patch], check the "patch keyvault" box and select the KV.bin modified in step 3
5. Click [OK] and choose output file
6. Flash output image back to the NAND of the US 360
7. Try an EU game or two.
My USA 360 just booted a PAL (non-regionfree) game. the region patching WORKS.News-Source: xboxhacker.net
