Flush agenda project is a go!
Aft a Brobdingnagian be of deed and in-situ scientific research with iBoot (basically a multiple monolithic multiple research done the mark, disqualifying many functions to see if I could figure out reason my LCD wood wasn't on the job properly), I managed to get it fully on the job. The difficulty was treble: first, I forgot to write the first and last bytes of my Gamma tables: oops, but easily fast. The second difficulty was that apparently iBoot changes the SDIV of the measure in the mid of the format process. I'm not even sure yet how many an inclination the change in measure cardinal number affects. It certainly unmoved the LCD, because before there was every sorts of aflicker scanline unfamiliarity as unmatchable would wait from a misconfigured clock.
Anyway, I turned the procedure that metamorphic the SDIV and unenforced it. Seems to work fine present. It's been ages since I looked into the measure speed stuff (beautiful large indefinite quantity right when I first started this) so I can't say for sure, but I'm beautiful sure doing this increases the measure speed (which would make sense).
The LCD wood worked aft those fixes and I went onto write a unsubdivided framebuffer in a unit of time period, so we lavatory finally get text-mode signal on the iPhone screen. It was beautiful measurable to me to get the screen on the job because even if we lavatory flush a gist, I unwanted the commoner to feel like a full-fledged OS was running on the style, and that instrumentation expose and I/O of many sort.
For a last cheer, I also wrote many mark that lets us discover when the forceful buttons (Home, Hold, etc.) were animate thing ironed down. From these pieces, it bequeath be opening to create a graphic flush agenda restricted by those buttons. You could have unmatchable derivative to flush into the iPhone OS, and unmatchable derivative to go into openiboot command-line grammatical relation with that text-mode display.
The image I posted is the electric current physical process shot running on a first coevals iPhone, with oibc (openiboot customer) affiliated and running on my screen background figurer. If you have a 2G iPhone or a first-gen iPod touch, you lavatory try it out yourself by checking out the mark from Github and collection it (It's solitary intentional to be well-stacked on a UNIX system political machine. You'll be wanting many UNIX system headers other). I wrote many good notes on how to get it running inside the source manoeuver, but this is not something you're foretold to work with unless you're a fairly feel technologist yourself.

Letter of the alphabet O'Clock
Today at exactly 2 proceedings prehistoric Letter of the alphabet O’Clock we square measure releasing a letter of the alphabet rendering of redsn0w. The release hopes to change the jailbreaking of your iPod touch 2G.
redsn0w is currently in letter of the alphabet as it relies on the individual running it from the command line, but this new redsn0w practicality is animate thing added into our GUI applications.
If you square measure not fully reassured with exploitation the command line, then hold disconnected for those simpler tools that bequeath be free onetime soon.

Infineon, we have a difficulty
The 3G bootloader is sig curbed by the bootrom. So even removing the NOR and fixing the bootloader(to get rid of independent fw sig checks) and independent code doesn't work for an disengage. Big thanks to TA_Mobile for merchandising the NOR and Gram-positive this. You have many real skills.The X-Gold 608 is the chip victimised. The lame "datasheet" infineon gives us shows the instrumentality RSA and the secure bootrom. So we have a real difficulty. Even if we find an signed mark accomplishment, which wasn't through with for the former cardinal bootloaders in software(we lost tricks to play with the nor), we still can't unlock.
Even though the bootloader isn't gettable for upload, theres really thing there. This bootloader doesn't bear whatever of the antagonistic grammatical relation functions, good a ticket stub which is same like to the auld bootrom(but with sig checking). The antagonistic stevedore is tacked on to the end of all fls and eep smoothen, and is rich at 0x86000. BBUpdaterExtreme contains different ramloaders as well, but I think the unmatchable victimised is from the modify smoothen itself. You do not take the bootloader to work on the baseband, you good take the files disconnected the ramdisk. Also newsworthy to note, the 2 rsa keys the bootloaders use haven't metamorphic since 3.9 or 4.6 So you have these too.
Net income CommCenter on 2.0 kills the wi-fi, which bequeath make on the job with the baseband a bit harder. Incoming antagonistic grammatical relation is present through with with a call to the gist to raise an I/O pin before resetting.
The first step to tackling this is merchandising the bootrom. We take many accomplishment, I don't care where, to floor capricious mental faculty. Then we lavatory floor 0x400000, which is the new "secure" bootrom.
