hello all

I have been playing around some this weekend since we now have a lot more options open to us, thanks to djrbliss and his new version of Loki that supports our phone

Please donate to bliss if you can

and if you can not, that is OK but please show your appreciation to him by writing a nice thank you post for him, the man has done a lot for us


If any of you have read this thread

http://androidforums.com/motion-4g-all-things-root/739805-ok-what-i-think-we-need-now.html

you should know some of the issues we need to deal with, I was pretty drunk when I wrote that thread, but the issues that it mentions still stand, mainly the data partition being wiped if you enter recovery, and my suggestion of using a boot menu is ok, but is a lot of work

i think i have an easier solution

lets just not use the internal data partition

I have created a TWRP and CWM recoveries that supports sd-ext, and a modified stock kernel that mounts sd-ext to data, instead of the internal partition

This should only be used by advanced testers, I have tested it, but not thoroughly

YOUR DATA WILL BE LOST WHEN YOU SWITCH OVER TO THIS

EVEN YOUR DATA ON YOUR SD CARD WILL BE LOST, BECAUSE IT WILL RE-PARTITION THE SD CARD

USE A DIFFERENT SD CARD TO TEST THIS, ONE THAT DOES NOT CONTAIN YOUR BACKUPS


You must be on version F firmware, rooted and have 2nd init recovery installed

MAKE A BACKUP IN 2ND INIT RECOVERY, AND THEN TURN THE PHONE OFF, TAKE THAT SD CARD OUT, AND PUT IT IN A SAFE PLACE, AND PUT ANOTHER SD CARD IN THAT YOU DO NOT CARE THAT IS GETS WIPED

get back into 2nd init recovery

download this

CWM version
lgm-f-cwm-data-sd-ext.zip

or this

TWRP version
lgm-f-twrp-data-sd-extb.zip

and copy it to this new sd card, then install it from 2nd init recovery

then go into the advanced menu and choose reboot recovery

DO NOT TRY TO BOOT TO ANDROID YET

you should now be booted into TWRP 2.5 or CWM 6

go into the advanced menu and choose Partition SD card

make the partition size at least 1024, you can make it bigger if you are using a big sd card

set the Swap size to 0

for TWRP press the EXT4 button
and then swipe the the thing to make the partition

you now have a second partition on your sdcard

the kernel provided is just the stock kernel, i removed wallpaper from it

and I change the mount line for data

from

mount ext4 /dev/block/platform/msm_sdcc.1/by-name/userdata /data nosuid nodev barrier=1 noauto_da_alloc data=ordered errors=continue

to

mount ext4 /dev/block/mmcblk1p2 /data nosuid nodev barrier=1 noauto_da_alloc data=ordered errors=continue


now when you boot into recovery your data will not be lost

I know this is not the best solution in the world, but it is an option

instead of using

/dev/block/platform/msm_sdcc.1/by-name/userdata

for /data


it is using the new partition you make on the sdcard

/dev/block/mmcblk1p2

for data

 

oh you should be using version F firmware too, I will update OP

 

no not really, but i don't to confuse people

 

that, and the current version of Loki should works just fine with D and E (me thinks)

 

to get Loki to work with C you have to change the check sigs address to


.check_sigs = 0x88F0FC78,

but it is not worth even messing around with it, i tested it and it still wipes the data, that is why I came up with this solution

 

what ROM our you on ?

 

I have been testing this on stock version F ROM

do you have version F aboot file loaded ?

 

when you have this new TWRP or CWM recovery


the proper way to boot into recovery will be to hold power and volume down


you will get a message about factory reset, press the power button twice and it will boot into recovery, it will wipe the internal data partiton

but it will not wipe the sd-ext, which is our new data partition

 

hmm, I did mention to make a backup in 2nd init, and take the card out and put it in a safe place, in big red letters

I am glad you did not lose any important data

let me know how your tests go

 

your welcome

 

OK, just make sure you are on version F aboot
