Root [Virgin Mobile/Sprint] overclock kernel V4 !

jhofseth said:
uh, easiest way for rooted vm720 is probably:
-->install android terminal emulator (play store)
-->download/save V4 boot image to root directory of external sd
-->in android terminal emulator type:
su <hit enter to become root>
cd /storage/external_SD/

dd of=ls720.original.img if=/dev/block/platform/msm_sdcc.1/by-name/boot

to save a copy of the existing boot image, and then the following to install the V4 overclocked boot image

dd if=ls720.overclockV4.lok of=/dev/block/platform/msm_sdcc.1/by-name/boot

you can do it all on your rooted phone w/o PC....so easy! thanks, Robaho :-)

I downloaded the overclockV4.lok file, & moved to ext sd, but where exactly do I put it? I can't find a folder named "root directory". I created 1, but terminal emulator says "no such file or directory". I know this question is probably ridiculous, but I honestly don't know

Just put the file right their their isnt a folder called root. Its just the main folder containing everything.

Is root directory /mnt/extsd?

root directory is just /storage/external_SD/.. Or it can also be /storage/sdcard0/. But if u put the file in that folder /mnt/sdcard/ then its samething. Then just use terminal emulator first type in su to get super user permissions. Then type in cd /storage/sdcard0/
or if you saved it too external sdcard then just replace sdcard0 with external_SD. After that copy and paste the commands to make backup of orignal and also to install kernel.
 
OK. I put file in ext sd (not in any folder) then, in terminal emulator, I typed: su <hit enter to become root>cd / storage/external-SD/
Then I hit enter.
What did I do wrong?
Thanks.
 
Yes, thanks to Robaho for his incredible work! But me,... Not so incredible. I'm stuck on the LG logo. I followed the instructions to save the original kernel, and can get to recovery from SD card, but can't find the file. Gotta sleep now. Will fix it tomorrow.
