You also need to change the thumb2 instuctions.

any progress?

**speddish** · 11-13-2009, 12:37 AM

Hi again, news? there is something I can help with?

Edit:
Does anyone have these files?
/usr/lib/libSystem.B.dylib
/usr/lib/libobjc.A.dylib
maybe from 3gs?

I did a stupid move by mistake and del springboard.app and I really don't want to restore
anyone wanna upload the springboard.app iPhone 2g 3.1 not 3.1.2

@Sk8r789456; Hope to be wrong, but probably if you load the springboard.app from another iphone (even same version fw) probably it wouldn't run cause of sign problem... If you have the custom firmware made to jailbreak you can try to extreact the folder from there. rename the ipsw in .zip, unpack it and mount the larger dmg... Not sure if it work but at least a try...

At this moment the only thing I have is an iPhone

**speddish** · 11-13-2009, 03:59 AM

Sadly I'm at work and can't take hands on my mac until this evening... the best I can do is give you springboard.app from 3G 3.1.2 ... sorry...

hey !!! I got the camera to be able to take still pictures !!! It freezes though, when you slide to video camera

Here you go, the modded AVCapture.plist which I used.

Download AVCapture.plist from Sendspace.com - send big files the easy way

can someone post the original 2G/3G Camera.framework ???
I messed up mine.........

just wondering anyway..............which Video Codecs does the iPhone 2G/3G have ???

It' s ok we have been able to fix the freezing problems, but we still can' t take videos :-( I' ll keep you updated.

What have you done to fix the freezing problems ???
Could you upload the files you modded ? I'll see what I can do with those files.

**mkblade** · 11-13-2009, 07:08 AM

^what he (&we) did was change the preset from "av" to "p" so that it would not freeze..but unfortunately that tells the iphone to switch to "picture" mode and so the screen you get is actually of the still-camera, not the video-camera...which is why when you press the record button nothing happens

Anyone else having problems playing YouTube videos? Mine wont play at all now

**koekje00** · 11-13-2009, 08:25 AM

I don't have any problems.

We still need to mod the VideoEncoders, etc. Has anyone found a solution to change the thumb2 instructions to thumb?

**rbisconti97** · 11-13-2009, 08:39 AM

my youtube will no longer play videos :-(

EDIT:

Got it, just deleted all the video stuff i had put in and replaced with my backups :-)

**ryanandkevin** · 11-13-2009, 10:32 AM

someone a while back ported them over to thumb, I think, if you get them I will port them to arm6

**joelchoy** · 11-13-2009, 10:47 AM

what's thumb? thumbnails?

**mkblade** · 11-13-2009, 11:33 AM

^Thumb is the instruction encoding and corresponding execution mode for the ARM architecture..like 3GS uses Thumb-2 while the 2G/3G only use Thumb-1 instruction set...in order to reverse one would need to use IDA

**ryanandkevin** · 11-13-2009, 11:45 AM

according to arm.com, we don't need to port these files at all from thumb2, they are backwards compatible:
Thumb®-2 technology is a new instruction set for the ARM architecture which provides enhanced levels of performance, energy efficiency, and code density for a wide range of embedded applications. Thumb-2 technology builds on the success of Thumb, the innovative high code density instruction set for ARM microprocessor cores, to increase the power of the ARM microprocessor core available to developers of low cost, high performance systems.

The technology is backwards compatible with existing ARM and Thumb solutions, while significantly extending the features available to the Thumb instructions set. This allows more of the application to benefit from the best in class code density of Thumb.

For performance optimised code Thumb-2 technology uses 31 percent less memory to reduce system cost, while providing up to 38 percent higher performance than existing high density code, which can be used to prolong battery-life or to enrich the product feature set.

This means none of these files need to be ported to arm6 or thumb, because they are all backwards compatible, it must be something inside the files like the framerate or screen recording size

Look at this
