OVERCLOCK KERNEL

FOR THE ZTE MERIT Z990G




BOOGY V2.0.777




FEATURES:

supports ext4 filesystems

swap capabilities


max cpu freq set at 777mhz by default without the use of any apps or scripts--a first of its kind for this device


*install from either stock or custom recovery*





DISCLAIMER: I AM NOT RESPONSIBLE FOR ANY DAMAGE TO YOUR DEVICE SHOULD YOU DECIDE TO USE THIS MOD. THERE COULD BE CONSEQUENCES FOR RUNNING THE CPU TOO HIGH OR TOO HOT. USE AT YOUR OWN RISK--BECAUSE, YES, IT DOES ACTUALLY WORK.





INSTALLATION:


!!!MAKE A BACKUP BEFORE YOU DO ANYTHING!!!


Code:
1. copy zip to the root of your sdcard--if on stock recovery rename to update.zip

how do you get the ext4 working


that's a good question...


it requires reformatting the /system, /data, and /cache partitions to ext4.


but there's not a tool to do that for these phones "yet" that i know of.


i just added the capability for the future of the device but my next project is writing/modding some scripts to do this formatting that way we all can enjoy what's in this new kernel.

okay how about mount2sd? it has a setting of switching ext and data but ive been trying to get the sd portion to get recognized but ive had no lick what so ever


i think you're confused...

mount2sd has nothing to do with this kernel or formatting your partitions. that's for mounting apps and their data to your sdcard.

the kernel supporting ext4 is to support your filesystem, ie. all your data partitions--cache, (dev--if it's used for dalvik-cache like i do), data, and system--being formatted to ext4.

i can actually make the kernel support many filesystem types with the click of a button. i was experimenting with the secure fs system but i ran into some troubles and just decided to stick with this for now.

oh okay then yes you are right i was confused. i was thinking that had something to with portioning the sd card with ext4 ive been trying to install ubuntu on the phone so i need an ext4 on the sdcard to be recongnized but i think i would need a kernel that supports loop and an ext

actually, in the end i think you were right to begin with.

this kernel will support ext4 for sd-ext partitions and loopback (as far as i know).

mtd is incompatible with conventional file system types such as vfat, ext2, 3, 4, ntfs, etc. there is no way to format such partitions to ext so the capabilities in the kernel are strictly for the sdcard after all--and more beneficial for devices that have an internal sdcard.

mtd can't become an ext partition. period. so in the end building this kernel for such purposes has been useless.

but this isn't surprising because of all the misinformation that is spread all over the net about android developing by people who don't know what they're doing. it's not the first time i've experienced proving conventional android wisdom wrong lol

but at least we got an overclock kernel (with more on the way)

i agree thanks for the kernel. is there a way you can set the overclock higher? or figure out about that mtd thing lol i wish i could work on the phone myself but i have no computer thats why i want to install ubuntu on the phone so i can at least try to some development too and again tanks for the kernel btw i got your recovery installed too ;-) youve done a great job

:thinking: I hit 1400 on bare bones (no apps) at 600mhz... I even have a snapshot to show it.

This was when I was assembling AreaROM 1.1, before my Avail died.

your snapshot clearly says 600mhz, not 1.4ghz

1406 is your score--add everything before the 600mhz on that screen and you'll get 1406. your cpu was never running higher than 600 when it was tested

my phone scored a 3226 without the oc kernel...

Hey boogy, gotta say I'm impressed. Been looking at some of your GitHub work, and looks like you have a pretty good idea of what's going on. ;-)

I put Phydeaux ROM on my phone many months ago, but really missed the OC feature that SpeedFreak offered, so I was glad to see your kernel here.

I went ahead and installed it, and everything seemed to be fine. But, I lost all my SD card swap stuff, so I did a restore for now until I get time to get it all working with your kernel.

Is this kernel on your GitHub area? I didn't see it, unless it's under a different name. I'm getting more and more into learning the true OS aspects of Android, and would like to start developing some day, so I just wanted to get some good pointers from someone that has your experience.

Thanks for all the hard work! The results show. :)

my github is out of date for this device.

and no, i haven't posted the overclock source. mainly because they are some flaws in it that i haven't fixed yet. the device really can't handle any more than this though. at 7.9+mhz there is a wake from sleep bug that i can't seem to fix. it has to do with the freq wake lock in the kernel, i just haven't really wanted to work on it.

i can give you some pointers if you need them, just pm me sometime.

thanks for the kind words
