Root [Virgin Mobile/Sprint] Overclock kernel and V6

Setow said:
Robaho, can you and xclusive work together to create a CM Rom that has overclock as well as the app2sd pre-installed? I don't like the stock ROM (I think alot of us agree on that), too many issues and it just gets tiring. I want to have a decent working phone. Any help will be greatly appreciated.

What issues do you have? I nearly never had any problems on the stock ROM!

Well its mainly the storage issue, I constantly have to delete apps to get any space free. But besides that apps constantly keep force closing, I believe it is more of a ram issue. Idk, I just would prefer a CM rom. I dislike anything besides vanilla android.

The kernel I posted will free up about 250mb but I have no realized that it won't work as designed for most people.

You need to wipe the dalvik cache then install the boot image then reboot. It's easiest when booted into cwm recovery.

I think he's referring to the stock rom not your kernal
 
Thanks, robaho! Installed oc kernel boot image by pasting your dd commands in Android Terminal Emulator--after switching to root via "su -". Enabled universal init.d with 'Pimp My Rom (beta)' app and this enabled/made-visible re-apply cpu (tweak) setting with init.d option in 'System Tuner' app. I also use 'Overclock Widget' app, but such could be reduntant. 1728 runs like a charm with ondemand governor! :-)
 
Just got this up and running. Here's a guide (might be superfluous) for new users:

For those of you already on v6, you will need to use the unbrick method here to roll back to v5. I linked to npolite's version of the guide, which is quite a bit more detailed, and cleared up some confusion for me, but his link to the Flash Utility is incorrect; use this one and make sure to put its Megalock.dll in the install directory (should be C:\LG\LGFlashTool). Carefully follow each step in order.

Once you're at the step where the phone is booted successfully on v5, you'll need to get root. Saferoot works both before and after the v6 update, here is the link. Ignore the verbiage in the post about it being for Samsung devices; it's confirmed working on our LG Optimus F3.
If you used the unbrick method, you already have the USB drivers needed; if not, here is the LG United Mobile Driver, needed to get adb (and saferoot) working.
As outlined in the Saferoot post, you will need to enable USB Debugging in Settings/Developer Options, and select Media Sync (MTP) in Settings/PC Connection/USB Connection Type. You should then be ready to run saferoot. Run its install.bat, THEN connect the USB to your phone to 'detect' it. Saferoot will start, follow the directions it presents you.

Once you have root, you'll need CWM Recovery. The safe way to go about getting this is with second-init. There's a guide here to go about getting that set up. Ignore the first three steps, you already have the drivers, USB debugging and root; do copy the "lte2_l1m_recovery.apk" and "CWM Recovery.zip" from the zip to the root of your phone's SD Card, per step 4; ignore steps 5 and 6, you already have root; follow from there to finish.

Once you have root and CWM, you have everything you need to follow the guide in the OP. Copy the loki-fied kernel from the bottom of the OP to the root of your external sdcard, as instructed.
Here is an installer to get ADB as quickly as possible. By default it installs to C:\adb, but you can install it anywhere.
Open a command window from the directory you installed it to (shift+click folder/Open Command Window Here), then:
adb devices
Click to expand...
to make sure adb is recognizing your device (LG-LS720-xxxxxx device), then:
adb shell
Click to expand...
to start adb, then:
su
Click to expand...
to get root shell as outlined in the OP.
I suggest carefully copy+pasting the commands listed into your root ADB shell window, to make sure syntax is correct. Once adb has finished copying the bootimg, you can close its window.
To install the patched v6 update, copy the update_patched.zip from the OP's link to the root of your SDCard, then power off your phone, enter CWM with vol-/power button combo then select (volume buttons to navigate, power button to select) 'install zip from sdcard' / 'install zip from external sdcard' / 'update_patched.zip' / 'yes' - Let it do its thing, then select reboot system now to boot into the updated system (with the o/c kernel - the update does not overwrite it). It will indicate that root might be broken - it is, neither option does anything to help, so select 'no' when it offers to fix it.

Once your updated system reboots, you will need to get root again. Saferoot will do the trick - run the install.bat, THEN connect the USB cable, let it do its thing, one more reboot, then you should be overclocked, rooted and updated.

I found that the linked file to retain thermal management gave me much lower benchmark scores - 10654 on AnTuTu - so I strongly recommend disabling it entirely. This can be accomplished with Root Browser - navigate to /system/etc, rename thermald-8930.conf to thermald-8930.bak to backup the old one, then long-press thermald-8930-empty.conf / Create Shortcut at the bottom of the list / tap Create, it will create a 0.00b file / long-press that file / Rename / thermald-8930.conf
Once I did that I reran AnTuTu and got 16410 - not as fabulous as the OP's, but still excellent. I suspect the thermal management was holding back the GPU overclock especially - the graphics benchmarks ran much better without.

Whew! All done! I hope this exhaustive, obsessive guide helps someone like me get this excellent device running even better! Thanks robaho and all the great people on the forums that made this possible.

I am certain the resulting file needs to be thermald.conf - however it is linked. Usually this will be linked to either thermald-8930.conf or thermald-8930-empty.conf.

Also, I am working on V3 with better cpu overclock. The results are not what I expect, and you are correct that almost all of the antutu increase is due to the gpu overclock - great for gamers...

Thank you for this, the OC is working now for me. Should i be concerned if my phone gets warm while running intensive games?

Most modern devices have built in thermal protection which will shut the cpu down if it gets too hot.

The devices thermal protection is to try and avoid the shutdown by making it run slower till it cools down.

You can probably adjust and enable the thermald.conf file- just enable the highest temp action - if you're worried. I'm not a gamer so it doesn't get hot for me.
 
How's the battery life with this overclock compared to stock? I noticed a big chunk of battery missing in the first two screenshots in just half an hour, but you have percentage off. My battery menu under settings expects 24 hours battery with 100% at stock.
 
Battery life i wouldnt say is any worse. But id like to thank Robaho for hard work in making this i installed it without problem and i think it makes world of difference!
 
Only question i got is if i wipe dalvik cache wont that mess up stuff like in different thread? I got kernel installed and working.

You really need to delete the /data/dalvik-cache directory from cwm. The boot image will recreate it as a link on /cache during boot.

It is harmless to delete. The first boot after Will just be slower.

Wiping dalvik-cache from cwm should have the same effect.

Your only getting that error because the O/C kernel file isnt spelled right look hard at it and ull see it is missing a letter. I had same dd if=ls720.overclockV2.lok of=/dev/block/platform/msm_sdcc.1/by-name/boot at first. Just rename the file to overclockV2.lok the original file is named overlockV2.lok

I'll try and correct.
