Xperia X10 Rooting and Custom ROM Development

I will have a look. Do you need them decrypted? Filenames preserved?

@dejanet - could you send me the files you sent to jerpelea? I need the two SEUS files containing R1EA018 to decrypt.

Is anyone working on cracking the boot loader so we can start flashing custom roms? I'd like to help. What communication channels are available?

Thanks.

nand extra driver

hi, all

I modified original msm_nand driver to access X10 nand non-public area.
kernel module binary and source code is here.

http://hotfile.com/dl/51628399/a786944/mtd_nand_ex.tgz.html

it is built for japanese version kernel, so if you want to use this.
maybe you should re-build driver module.

next step : break the bootloader... yes, goroh_can !

With this, is it possible to install other drivers (like the camera one) on custom ROMS ?

nand raw image dump with extra nand module

I uploaded mtd dump program for xperia with my mtd_nand_ex module.

It includes souce code, and static linked binary.
http://hotfile.com/dl/52240500/a1a6e72/mtd_raw_dump.zip.html

With normal mtd-utils(nand-dump), you can't rip complete nand image.
so I have to change mtd mode to RAW MODE.

the raw image includes OOB(Out Of Band) area, so we have to
calculate ECC（Error Correction Code） to get its executable image.

Impressive work, that should help out.

Check out android/kernel/drivers/mtd/devices/msm_nand.c

^The Sony PS3 also uses a similar method to boot Linux, in this case a custom kernel/initramfs is located into firmware. This kernel then boot the "real" Linux system using kexec.

k1ckn1ck · Jul 7, 2010

no proper way to hack the bootloader then?

sabianadmin · Jul 7, 2010

ok cool, so then lets start talking about what needs be done to patch the boot loader because that will make it easier to flash on a per rom basis

rosco16 · Jul 10, 2010

Great!!!

If you had flashed NAND ...is it correct to say that x10 is root 100% already ??

cheers

Not necessarily. Just because you can write the software to nand that doesn't mean you have something ready to write. It's an important step on the way but it's not the final solution. We still need a bootloader that doesn't check the ramdisk and since we haven't heard anything about that yet I presume it's not ready.

NO
- we can dump and flash nand (tested tools)
- SE boot (kernel is signed like .sin files) and our boot is not signed so it will not boot

WE need kexec to load our kernel or patch bootloader not to check for signed kernel

@custom rom Cyanogen V6 alpha is compiled but we can not boot it

Dump the bootloader, patch it, then rewrite.

it seems likely no way to go about Custom ROM..........

hey have some faith, these devs are brilliant! I think they can do it, we just need to give them some time. After all getting the bootloader sorted is probably the hardest thing to do.

strix75 · Jul 10, 2010

i just don't understand all people that demands all devs to fix custom rom hack bootloader, don't you understand that they are doing all they can. if you are not happy what the devs are trying to do fix it yourself then and stop crying like a baby over the progress. this take time to do and there is no magic formula, just hard work.
so please just stop naging.
