If you flash the newer i777 leak that DG posted in the General section (I777UCKJ2) or went a little crazy and accidentally flashed one of the newer firmwares in the SGSII international section -- you'll find that they contain newer bootloaders -- the main difference being that they render the "jig trick" useless for resetting the custom firmware flasher.

This (if it works as advertised) will allow you to revert back to the older (stock) bootloader that will let the jig reset the counter.

Most likely as new ROMs are built for our phones, many devs will remove the bootloaders, since it's not really advisable to flash these unless absolutely necessary (which for instance it was on the Captivate when flash from a Eclair/Froyo ROM to a Gingerbread one).

Put this in another post too, but felt I should mention it:

Be forewarned -- DO NOT mess with or flash bootloaders unless you absolutely know what you are doing or are sure you need them. May things can be recovered from if things go wrong, but a bad bootloader flash can create a nasty "brick" that almost always needs some sort of professional help to undo.

Phone: Samsung Galaxy S III (i747) on AT&T
ROM: PMuttStyle v1 (Custom UCDLK3 4.1.1)
Kernel: Intergalactic 2.6 Kernel (LL1)
Modem: UCDLK3

Primary Tab: Galaxy Note 10.1 (N8013)
ROM: Android Revolution HD 7.0 w/ Darkman's Compat Mods (XXCMD1 - 4.1.2)
Kernel: Stock N8013 (XXCMD3)

Backup Tab: Galaxy Tab 2 7.0 (P3113)
ROM: DMB4 Root/Deodex (P3110 - 4.1.2)

Will this help with heimdall detecting the phone on Macs? I hear the bootloaders cause some Macs not to see the phone.

This reverts to current if you flashed the 2.3.5 leak package accidentally.

I would advise:
DO NOT flash this bootloader unless you have flashed a 2.3.5 leak or I9100 ROM that included bootloaders, AND you have confirmed by trying it that using the jig does not reset your flash counter.

If you don't have a jig, this does nothing for you except risk hardbricking.
If you have a jig and it works to reset the custom binary flash counter, this does nothing for you except risk hardbricking.

No. That was a problem with early I9000 bootloaders, and it didn't cause heimdall to fail to see macs - it would cause heimdall to potentially brick a phone.

That flaw DOES NOT APPLY to the GS2. As I stated above, if you have not flashed a bootloader before, this will do NOTHING except risk hardbricking.

confirmed working. I had flashed the kj1 and then kj2 roms a while ago.
I hated seeing that triangle at boot.
