A bit of info about the update and modified DVD firmwares:
As general rule, if you have a modified DVD FW we always suggest you wait till more details come in before you update your console or you can flash back the original FW. As always, update is at your own risk.
As you know from Commodore4Eva received information that Microsoft is working on a way to detect backup discs (the disc, not the flashed drive!). He already released a new Xtreme v5.3 firmware for Toshiba-Samsung TS-H943[/url] with added Disc-Jitter to Challenge Types 5/7 to pass this extra check Microsoft might do.
So if Microsoft adds the Disc-Jitter check to the Spring 2007 Update and you have a TS-H943 drive with the new v5.3 Xtreme FW, you should be fine (assuming they didn't add any other checks of course).
If you have a Hitachi-LG GDR-3120L drive with modified FW, we STRONGLY suggest you do NOT upgrade your dash/kernel yet. These modified FWs do NOT have disc-jitter added yet, so if Microsoft added this check they will detect backup discs. People are working on a quick patch for Hitachi-LG Xtreme v2.x FW to just add Disc-Jitter and eventually it'll catch up the Toshiba-Samsung drive to bring it to v5.3 as well. We'll of course let you know as soon as any if this gets released
What will Microsoft do when they detect this? That's something we don't know atm, we'll have to wait for the update. They will probably stop the game from booting, but they could start banning consoles from LIVE too (even if that might cause bad press) or who knows what they planned
. We'll have to wait and see ... but remember Microsoft has the tradition (see Xbox1) to ban consoles with delay, so don't take conclusions too fast
