i mean while the bounty would be nice, this is not my main concern. I just want cm7 to work well. So we need to be able to flash kernels... That is it. CM7 is friggin awesome and would be the best thing for our phones it possible.

omg this def just got over my head, unless i can find in the source where this value is set in a function (which i am going to search high and low for) i am at a stand still. Maybe you might be able to help here prime. I just dissasembled the function call and its just wayyy over my head i have no idea what i am looking at. I can read C but this is rediculous.

bingo found the function! Basically it calls another function omap_type and gets a value of 1 or 2 from it which then sets the string in proc. so we need to hijack at the point of omap_type and return 2 instead of 1

edit: im going to work on this more tomorrow. Im tired.

Goodluck man!This is the only way we can go back to its orig kernel..wish we can unlock the bootloader...unlocking it...we can do more:)....and a lot lot more.:biggrin:

Thanks again for all ur hard work. See they got overclock working ovrr at rootz? Running 1.5ghz... smushing rzr rezound AND Overclocked sgIIs... no problem :)

update: i gotta install debian on my pc here so thats going to take a little time that way i can go through the source code for the kernel (its where the functions i need to hijack are) once i can get the platform built and dissasembled i can go from there. bear with me guys im trying. as of right now i am just working on the OC then i will start on the unlocked bootloader. if anyone wants to try to do what i am doing here follow milestone overclock wiki dissasembly instructions. the function is different on our phones so it is going to take a little longer and anyone with C++ knowledge should be able to break apart the coding for the bionic.
Edit: also with tday tomorro and im getting a tat today dont hold your breath just yet. pm me if you think you can understand what they are saying in the dissasembly and ill let you know how far i have gotten.

Tat on my painted brother, lol

Hey ex0rcist, can you post a link to rootz, that I might further my knowledge base : grinnin:

Good work on the disassembly, I do not see the call in what you posted. The numbers to the left are memory addresses, the next are 'jumps' to other locations, finally there are the instructions on memory manipulation of the location.

I didn't know there was a binary to omap_dev_type but being there is the source is where the answer lies. I have the sources but have yet to decompress all of it.

ok so if you have not gotten it uncompressed and instead of you finding it yourself ill just post it here

boy isnt eclipse wonderful all i had to do is load the kernel source into it and search for the function with it and boom pops up everywhere those things are.

we would need a kernel module to run over this changing the value after its been set. And we would need to do it in stock recovery. Then install an update and cross fingers.

are you capable of doing that or not? or is it even possible yet?

well making the module is completely possible, running it in stock recovery is the tricky part
