[DEV] Compiling *working* a kernel from source

---

Has anyone done it?

I did a few runs with the m2_att_defconfig and the defconfig I pulled from the stock boot.img but I've had no luck with either. I'm fairly certain I'm repacking my boot.img back correctly, but that could be an issue as well.

I've uploaded the kernel source to github as well as the defconfig I pulled from my phone in case someone wants to save some time.

I wonder if the ominous "QUALCOMM SECUREBOOT: ENABLE" has anything to do with it too.

Anyone have any thoughts? Ideas?

Please stay on topic here

Edit

mdeejay is a genius. It works with the following:

./mkbootimg --cmdline "console=null androidboot.hardware=qcom user_debug=31" --kernel zImage --ramdisk ramdisk.gz --base 0x80200000 --ramdiskaddr 0x81500000 -o ./boot.img

I have been getting nothing but errors, can't figure it out. I'm trying for just stock right now.

try it

Have been working on this 'problem' now for nearly a week with testers (I have the International gsm model) and no luck at all. Tried unpacking/repacking with/without the command line using manaul methods and automatic but always hit a bootloop.

I NEED to be able to work with these boot image for AT&T/VERIZON/SPRINT and also TMOBILE for my US S3 ToolKit so if anyone has any insight what is needed to successfuly repack the boot image please share. I have been working with boot images from NAND backups as that was the only image available to me until yesterday when Adam Lange published the Odin Stock Roms for all the carriers so I will have another go today with those.

@ mdeejay is that a repacked boot image for Tmobile? If so and its worked for you please could you share how you managed it?

Hey Romanbb I havent had a chance to look at this yet do you mind sharing the params you had to use packing the boot image.

Thanks, Mark.
