[TOOLKIT] Dualboot CM9 and FakeCWM for Sprint SGS3

---

Link: Dualboot CM9-on-EMMC for Sprint SGS3

The CM developers are rapidly fixing bugs in the CM9 nightly builds, however it might be a while before CM9 is dependable as a daily driver. Thus Team Epic has created this toolkit of CM9-on-EMMC and FakeCWM to allow both developers and testers to rapidly test standard CM9 .zip's. The phone's standard ROM and kernel are intact so you have a stable ROM to fallback on.

• The alternate ROM is stored in /sdcard/multiboot/CM9 of the "internal sdcard" storage. Booting the alternate ROM is temporary. Reboot the phone to return to the standard ROM.
• FakeCWM Recovery is used to install, upgrade, and manage CM9-on-EMMC.
• If there is demand, we can adapt this CM9-on-EMMC method for other SGS3 LTE variants.

Follow Sprint SGS3 CM on Google+ for the latest development news relevant to this phone.

Thank you thank you thank you!

EDIT: will this work with the newest versions of CWM? Such as CWM Touch 5.8.x.x?

Unclear. It might only work with CWM that has a kexec enabled kernel.

That's what I was thinking. Ah well, it'll be worth using whatever recovery necessary to have the ability to dual boot!

EDIT: Got it up and running. Very nice! Thanks again!

EDIT 2: While restoring from titanium backup the app keeps freezing. I went to the Play store to try and download the apps that wouldn't restore and received an error message saying there was insufficient space. Can you make the data.img larger?

This is BAD @SS

Awesome!

*ninja edit: THNX to the kexec tools above, this CM9 is purring along nicely!

Gr8 set of instructions, no major hiccups so far......SMS/data/phone/email/play$tore/downloads/camera/video@1080p............yup, feels good to me!

fun fun fun...........really awesome bit o'
work w/ this, bbelos + mkasick, looking forward to running this awhile as it appears to be pretty solid for a first release on the S3!

just awesome sauce!
