Is it just me? [Cellphone performance] Reply to Thread

I can relate, i have a p500 optimus t which is a optimus one i guess. Owned it for like 3-4 yrs now just around 3 1/2 4 yrs into owning it i found out i could update it to GB 2.3.3. I did that and i really didnt understand the change other than the look. Plus i was told that my phone wasnt able to be updated from 2.2.2 by the tmobile techs "Well, yea it can bub" lmao but i see many flaws p500 has with speed, i try to understand the roms and now i see the differents, going on youtube and watching people overclock and playing highly rated fps games on the same phone i have...WTF how can i do it. I follow their instructions, but i take it that its not to the T. I still end up unable to overclock it right and not able to match their performance ON THE SAME DARN PHONE!!! So i ended giving up for a while cuz i wanted to throw the phone into the trash but now i can relax cuz im starting to understand it more. :laugh:
[GT540 Optimus General] -Grift-:
Its the cpu degrading i guess.... But now my gt540 has a half dead screen :) Its lucky yours is still in usable form
[GT540 Optimus General] Ziore:
Nah, benchmarking was just a way of showing how my cellphone sucks :P.

Well, I think I will just stay with some 2.1 or 2.2 D:
[GT540 Optimus General] -Grift-:
Dont think that way! You score 400 less and i score 1000 less :D:D:good:
[GT540 Optimus General] Ziore:
Only difference is that you own a SII lol!
[GT540 Optimus General] coto39:
I think the thing that is happening to you is because OC has degraded your processor... My phone have 1.5 years old and mantains the same speed and even gets better with newest and more optimized roms (ex. sdsl)+scripts and some tweaks. I don't use OC or swap... I only used a little OC for the first versions of ICS, then nothing. With swap on ICS I feel that my phone is slower than without. Yes, i have less app-kills but restoring apps from swap on sd is too slow (on my class 4 SD card) :/
[GT540 Optimus General] -Grift-:
Nonono i mean my old gt540 :) I used to use swap on my gt540 o.o class 4 8gb card :D
[GT540 Optimus General] androidboss7:
yeah i had a gt540 for one year and so far no lagg. i am using stock 2.1 rooted and i reckon stock is the best

rom out there. i havent flashed for a long time so i decided to flash ICS today and see how it goes.

If your phone starts feeling laggy or slow just flash a KDZ rom to it and it will be normal again.

Almost all problems are solved when u flash a KDZ rom.

[LG Optimus 3D] avengin:
I agree with you, I did notice things seemed pretty mellow here vs other forums, this'll be a great start for those of us that are picky and wanna combine and mess around with stuff. And i wasn't totally sure where to look for kernels and rom building so thanks this should make the community a little bigger. And i'm sure we'd end up providing some better support than lg lol
[LG Optimus 3D] xstokerx:
love it gj cant wait for the custom kernel section cuz thats what i am interested in is building my own kernel
[LG Optimus 3D] pandaball:
Just a few comments if I may:

I use 7zip over Winrar, it's a pretty badass alternative for something which is free.

Also, making a CWM backup isn't entirely necessary, you can do adb pull /system and the files will be pulled over to your adb directory. Saves you the trouble of extracting the nandroid backups. Normally I don't touch /data at all, just create /data/app and add the necessary lines in updater-script and you're good to go.

Some more tips:

Get the LG source code, it really tells you how Android works and all.

Linux is better than Windows for things like this. Both work fine, but Linux has the compilers and tools.

Test, test and test again. Make sure everything and everything works. Failure to do so (like I do sometimes :rolleyes:) will result in horrible things happening.

CWM's updater-script is a PITA. If there's an install script error, check your syntax. Did you forget a semicolon? A quotation mark? Did you ensure you used the correct command and parameters? If you really have to, weed out your updater-script down to the very basics and debug from there. Nice things such as ui_print are unnecessary until you're sure the basic functionality works.

Finally, doublecheck your permissions. Don't make everything 0777 (rwxrwxrwx) for no reason at all. Assign 0755 only when it's needed by the tweak, else 0644 will suffice. Also, things like su and busybox require special permissions like 4755 and 6755. If you don't assign these permissions, something's bound to break. Make sure your permissions are assigned correctly, else you have only yourself to blame when you bootloop your phone.

tl;dr it sucks to be a developer :p

Getting There

Almost done guys but been busy setting up my old laptop so i can take my stuff to work and work on it in my break, which will be good ics comes out i will be able to jump straight on it.

Toolchain link fixed and most of the kernel bits done. You could use the rest of another boot.img guide for now if you cant wait for mine.

Also are there any other dev's willing to contribute to my bible post. I would be grateful and it would be more of a community thing then. Any tips tricks, links, dev related story's or something to push the development on in here.

hi samno thanks for the tutorial but if I want to compile the kernel i get this error:

I tried it with root to but the same error.

I hope it isn't a too silly fail and I didn't forget something.

greets berni
[LG Optimus 3D] samno:
Sorry berni the syntax error is because of the _'s & ()'s in the directory name, rename it to something similar but without them example LGP920v21ESource. I will amend the op forgot about this since i set mine up a while ago.

i'm not sure if I'm the only one who gets errors like this:

but it is easy to fix just rename the

/home/bernhard/Downloads/arm-2010q1/bin/arm-none-linux-gnueabi-nm

to arm-none-linux-gnueabinm

after fixing this it was no problem to

make the zImage

thanks again for this guide!!

---------- Post added at 08:13 PM ---------- Previous post was at 07:52 PM ----------

I just wanted to add some stuff to this guide :

after you compiled your zImage you want to

test it but how?

Parts of this are taken from Urabewe guide so credits are going to him

first run this in terminal :

sudo apt-get install uboot-mkimage

then you have to unpack a working boot.img

with this script (link by samno):

http://xdaforums.com/attachment.php?attachmentid=1215193&d=1342992085

unpack it and put it in the same folder of boot.img

cd to this folder in terminal

run in terminal

./unpack-bootimg.pl boot.img

you should now have a directory called boot.img-ramdisk

here you can add some tweaks if you want.

If you change some things in the ramdisk you have to do this:

place now your zImage in that folder and run

mkimage -A ARM -T multi -n NAME YOUR IMAGE -C None -a 0x80008000 -e 0x80008000 -d zImage:newramdisk.cpio.gz newboot.img

now you shold have a file called newboot.img just put it in a zip

and flash it from cwm but make a backup to restore the boot partition

if something wents wrong

hope i did not forget any credits or steps

I wonder why the export command sometimes doesn't do :/

I had to copy the files contained in arm2010-1 into /usr to get it working with CROSS_COMPILE=arm-none-linux-gnueabi

Without this was starting the arm-linux-gnueabi already installed in ubuntu which gives errors..

Anyway i'm doing experiments with sources and kernels here.. :) i feel like a mad compiler doing my "frankenstein" kernel..
[LG Optimus 3D] Deadly:
why dont you edit makefile inside "common" folder?

look for lines like this.. yours may differ.. as my kernel is for samsung device.. but similar lines will be in makefile.. so edit it to put your path for cross compiler ..

this way you dont have to use export command whenever you open terminal...
[LG Optimus 3D] Pesach85:
Anyway i got successfully my zImage with experimental menuconfig settings:

i discovered that with the p940 defconfig is configurable the type of LGE platform (korean three keys or other, RAM 512 mb or 1024) but i guess it compiled the IPS stuff which is not compatible with the P920... anyway just an experiment :) was interesting to see how it works :)

Indeed my goal is to obtain some .ko GPU clock and RAM clock modules if possible to insmod in actual ICS :)

I' m still noob so i could say enormous fantasies and few concretes stuff :)

is there a way to read the active ram clock?

First of all, thanks for this great guide.

I have a doubt about this case, i have a my zImage, and a ramdisk from a unpaked boot.img (using the same way and files that sanmo used in first post) Now i compress the ramdisk

find . | cpio -o -H newc | gzip > ../newramdisk.cpio.gz

And i have my two files zImage and newramdisk.cpio.gz, well, in your post you say that the way to compile de the boot.img file is different, what happend?? can't i use the comand

mkimage -A ARM -T multi -n newboot -C None -a 0x80008000 -e 0x80008000 -d zImage:newramdisk.cpio.gz boot.img

to compress the boot.img file in ICS??

I think that the kernel base address and ramdisk base address are different, or not?? were could i look for that address?

And then, when you have a boot file, can you paste it in a kernel.zip file for get the kernel??

Thanks in advance, and sorry for my noob doubt, but im very very interested in tihis world, and im trying learn more about this.
[LG Optimus 3D] Benja_Bueno:
Hi again, one of my problems with the boot.img file is that i need to signing it.

so my question here is was i supposed to use that file? or i need a completely new zImage or thats not the zImage??

All tests used the SSK Driver-Free 1.3 Mega Pixel USB Webcam with Microphone & Clip - Black + Orange and the Creative Webcam nx Pro Vista / 7 ( I think both are knock-offs, I can not find model numbers). The SSK stated it was UVC compliant and the Creative box says “NO CD Driver”

It's easy to get the USB device info from the Windows Device Manager as follows:

- right click on "my computer" on the desktop

- select Device Manager

- Doubleclick Imaging Devices

- doubleclick on your camera device - it might just say "USB Video Device" or something like that

- select Details

- copy the VID and PID numbers: eg: USB\VID_1e4e&PID_0100$MI_\6&20BD946A&0&0000

- reference the VID and PID numbers on the http://www.ideasonboard.org/uvc/#devices website

NOTE - if it works but it's not on the list, it just might be newer than the info on the list - please submit it to the list's maintainer.
