||
| − | I roughly know how ida works and what the keys are. I think there are some people that have already setup the right values for reversing the baseband. So what I want to see here is just a quick intro to set up the project (segments, fileoffsets, changed options, entry points and so on), not how to use ida. This should almost fit into your article above, just counting words ;-) |

||
| − | Yea, but if you don't understand how to get those numbers, you'll be pretty useless as a reverser. Not to discourage, but the numbers really aren't that hard to get. Look at the memory map I posted. All the information you need is here. ~geohot |

| − | Probably I missed something in the constitution, just to cite: "Let's document this device better than anyone at apple knows it." Fact is, you and some other people know how to set up the IDA project. If now, someother people, including me (btw. my first reversing was a CP/M in 1986), don't know how to set up it, one thing is clear: It's not documented. So if you guys reply to my request "this isn't hard to get", this actually means "it isn't hard to get for us" (1st) and "we _don't_want_ to document it" (2nd). This is against the constitution set up by yourselves! Should we change the constitution? My (tongue in cheek) proposal: "This pseudo wiki is intended for <fill in names here> to absorb knowledge. Everybody is invited to give us knowledge..." - The world could be that easy: Just give those people that lack some knowlegde a chance!!! And don't mistake knowledge with qualification. -caique2001- |

||
| − | == offsets == |
||
| − | For example, if you look into ICE2_01.45 using a hex editor, you will see starting 0x634 there contains the memory maps. It started at 0x20000000 and ends at 0x21000000 with sections in between doing its own thing. The code/data in the .fls starts at 0xCF8 indicated by location 0xCF4. The length of the code is indicated by the location at 0xCEC which amounts to 0x5E9E18. |
||

| − | So, you may want to load the data in the .fls file from 0xCF8 to 0X5EAB0F at offset 0x20000000 in IDA pro. |

More instructions
It could be great if someone writes more instructions for the other basebands and models.. I tried with the instruction for 3G baseband in 3gs 5.12.01 baseband and I got an error in IDA Pro... --L0g0 18:54, 29 July 2010 (UTC)

This page is correct and doesnt need an update. You need to read up on exploits if you want to make jailbreaks. Lately buffer based overflows have been used the most. Google it, Wikipedia it and understand what exploits are. Use IDA next. As for a tutorial, let me write one for you: 1. Find a function which can be exploited to run usercode, 2. Insert code to edit/overwrite fstab to mount (all) disks as read/write, instead of read-only. Optional 3. Transfer cydia.app. Done.
