Default [Kernel]OptimusM OC stock 2.2.1

Well here is an overclockable kernel for the optimus m that came with 2.2.1 stock. This allows you to change your cpus speed and has the potential to damage your phone if not used with common sense. That said, I AM NOT RESPONSIBLE IF YOU F UP YOUR PHONE! Every CPU chip is different so stable speeds will vary from phone to phone. My phone isn't stable above 787 MHz. That doesn't mean yours can't go higher

Download the zip to your sdcard.
Reboot into recovery.
Wipe your cache and dalvik cache.
Flash and reboot.

You will need setcpu or a similar program to change frequencies. I have to configure the gbrom so the cmod7 settings will have that ability. Hit the thanks button if this helps and the donate link if it really really helps

Big thanks to asadullah for organizing our mob on LG and making the source code possible!

Enjoy!


UPDATE:
This version works with any rom and wifi modules were compiled separately so wifi works right out of the box.

Lower set CPU Max Version, people with boot loops test this update
Max set to 729600(i can go lower if needed) and default governor is ondemand.
r.O.C.K-v0.3-AnyROM.zip
MD5 Sum: e5e905eb5fcd6a9e93a180c7e25c2b3d

In compliance with GPL, here is the source:
r.O.C.K-v0.3-Source

Battery Calibration install this and let your battery fully charge. The run the app, unplug the charger and calibrate. This should be done after flashing a new rom or kernel.

any specific way to flash this? i got a boot loop.

so I was trying to build my own overclocked kernel and was trying to follow this Overclock Android kernel for Sprint Optimus S to replicate the changes that were made

is this something close to what you did?

i've even tried manually repacking the boot.img with no success(with the offset too) i've even tried the scripts out there even though they do they same thing I did manually... i must be doing something wrong cuz I even tried unpacking the boot.img and repacking the same files and it wouldn't boot

is there something I'm missing??

using anreboot it just restarts using adb reboot recovery it just restarts.

That does the same thing as anreboot, and reboot via adb.
just boots the phone.

OK after the 3 time holding the buttons it worked, guess 3rd times the charm

Any way I can flash back the stock kernel without drastic measures? Can't get it out of boot loop and I really don't want to spend hours setting it back up from a restore, lol.

Did you do a nand back up?
if so follow the instructions above for booting into recovery and then restore.

you have to start from power off so if you just get boot loop pull battery for 10 seconds then hold the buttons

If theres is any info you need to help diagnose the boot loop thing I'd be happy to help.

I am running the cm7 rom with the mms fix, I booted into recovery and wiped both caches and flashed the kernel, it said nnnnnjoy when it was done, looked like successful flash, reboot just loops.

Had some trouble booting after flashing this in. Once booted, my system ran really slow (or at least, the live wallpaper ran very poorly) and of course there's the WiFi error. I also couldn't enter recovery through console commands, my heart sank for a moment when it would just reboot. Needed Vol - + Home + Power.

Thanks for your hard work reppard!

The wifi issue has something to do with the update zip because I add the kernel to a rom and flash that the wifi works. I'll work on this issue tonight when I get home from work. Sorry to you guys getting boot loops I will try to track down the cause.

I have deleted a few posts from this thread. Lets ALL try to be courteous to each other and realize that sometimes when things go wrong it is easy to try to take it out on others. We are all just trying to help each other out and there is NO need to be snide or rude.

If you see something that you think warrants a MOD's attention then by all means report it, DO NOT respond to it. (not even to say 'i reported you')

I will be keeping an eye on this thread in the interest of keeping the peace so please think before you speak(post).

You can just flash a rom and it will revert the kernel. Just don't wipe data and all should be good. You should however wipe you cache

if you used the stress test and it didnt lock up your phone or reboot then it works at that clock.

The longer you leave the stress test going the more stable that clock is.

For example if you set the cpu to 787mhz and run the stress test for 10 seconds and the phone reboots you know its not going to work.
if you back it down to 747 and it will run the stress test for 30 mins its probably going to be stable.

you wont know while its running just walk away for a while, if it hasn't rebooted hit the back button and it will tell you it ran for x amount of time and all was good.

For those of you with the know how until I get a flashable kernel update with working wifi you can unpack the boot.img of a rom and just replace the zImage file with the one from the kernel update. Repack it, drop it in your rom's zip and flash. You will have functioning wifi. This may fix any boot loop problems. I still don't know why some people have boot loops while others don't :/

For those stuck in a boot loop did you by chance wipe your data along with your cache? If so try flashing a working rom, boot up, reboot into recovery and wipe only your cache and dalvik cache, then flash the kernel. Let me know if this helps.

i was reading some articles on building the kernels and they suggest that you may have to recompile the wifi module separately for it to work.

so like... why the 4311 can't I repack the kernel into the boot.img!!!

what offset are you using to do this??

i've tried doing it manually with mkbootimg, with the upack and repack scripts and liquidmkbootimg... i've even unpacked a working boot.img and repacked it... and no luck?!... i need a drink!

I only wiped the two caches mentioned in the first post.

I don't know if this will help, but...

I bought SetCPU and flashed the OC kernel back in. I don't know how it's related, but the OC kernel causes my live wallpaper to chop up and not play smoothly. I already mentioned that, though. What's new; I ran my stress test stable at 787 MHz, but it crashed pretty quick at 806 MHz. Once it crashed at 806, it would not come back. It would only bootloop. Pulled the battery to reset it, went to recovery, and put my nandroid backup back on no issue.

At 787 MHz, the Live Wallpaper remained choppy, but ADW's screen animations and other menu scrolls were beautiful smooth on the otherwise-stock ROM.

Thank you, I actually just was able to use the power button to power off then do the key press, had to do it 3 times though must have slipped on a key the first 2 lol.

One thing to remember when you are using set cpu and overclocking DO NOT check the box to set on boot. If you do it will try to set the last speed before reboot and if it is not stable it will crash and reboot again, Probably all the problems with the boot loop. because this overclock kernel tells setcpu that the max of the cpu is higher, it adjusts it up to the max on boot, when it is needed to speed it up you know.

Every cpu is different sometimes you get the lucky side and have a cpu that can go higher 845mhz is I think the highest I heard of though I could be wrong.
Sometimes you get the short end of the stick and have one that cant got 40mhz over though I bet the short end on these phones is 747mhz or so not 640-80 some.

My phone was able to run stress test for 5 mins, all the time I let it, at 806mhz that is not enough time to tell if it is stable though. at 825mhz it ran the test for 5 seconds and rebooted.

That's the thing, the box was definitely not checked. I made sure before I touched the slider.

I forgot to add that to the last post.

Tried to play Speedx 3D with the OC kernel, and the game won't play. The graphics are seriously screwed.

So I played with the different clock speeds again. I definitely, 100% sure, had the set on reboot box unchecked, and I'm sitting here watching my phone bootloop after it crashed again at 806 MHz.

And now, after about 10 loops and the time it took to type this, it's stuck on the LG screen.

edit: got phone to boot without a restore by clearing the caches again.

wiped cache and dalvik cache.
boot past white lg logo,
reboots after about 1 second of second lg
after white logo again it got stuck at second boot screen for a minute of so,
then rebooted to white logo and stuck on second for for an extended amount of time.
no response to adb

pulled battery, booted and stuck at second lg screen. but atleast responding to adb... if only an error!
Code:
t3084@uFREEDOM:~/android/tools/bootimages$ adb logcat
- exec '/system/bin/sh' failed: No such file or directory (2) -
it rebooted after awhile, goes to second screen amd rebooted a couple times. now adb doesn't even give an error.

over and over and over >.<

i must say I like being able to update with the boot.img i couldn't restore my previous kernel with the first download.

if you can't boot up the oc kernel in this boot.img, instead of flashing the whole rom, you can flash 221kernel_CM07ramdisk.zip to go back to the stock kernel.

You flash the new one with no problems? If so I don't know what the hell these guys are doing . I tested by flashing the gbrom to revert to the old kernel and the flashed the updatem. Worked like a charm. Maybe it's something in the kernel that some people's phone doesn't like...
