[GUIDE] How to install touchscreen fix - Optimus One, P500, V General

It's really about time somebody made a simple, easy and straight forward guide for installing mik_os's clever touchscreen kernal patch thing. I'm not android genius and really struggled to install this having no knowledge of how androids really work inside. Trying to figure out how to install the much needed touchscreen fix was a disaster but I finally got it right.
Due to a lack of simple and easy to follow guides I have made this one to help out other beginners, who like me didn't receive the help they need despite hours of google searches.

Firstly this guide shows you how to root and then flash your phone with mik's fix. I'm not very good with androids but this worked and is pretty fault proof if you follow the steps. BEFORE BEGINNING MAKE SURE YOU HAVE FULL BATTERY!
1) Make sure you have Froyo 2.2. To check what version you have go to settings> about phone> android version. If you have 2.2.1 or something I really can't help you, do a bit of searching on how to downgrade. Explaining it will only complicate things if you are knew to androids like me.
2) Click this : http://forum.xda-developers.com/attachment.php?attachmentid=446145&d=1290341328
3) Save it to your computer, plug your phone into the USB port and copy the newly downloaded file onto it(by enabling mass storage device thing on your phone) and just pasting it in there not in any folder.
4) On your phone open the android market, search for Astro file manager. Choose to install it(wait for download and install to complete).
5)Open Astro File manager and locate the file you downloaded (z4Root by RyanZa) using astro (it'll be in the sd folder on its own). Select z4Root and install it and run it after installing.
6) Choose to permanently root your phone(this voids your warranty btw). Let it do its stuff, your phone will restart and you will be a super user! win.
7)Next download this:
http://www.mediafire.com/file/uf752h914q0u228/recovery-RA-GNM-thunderg-1.1.0.img.zip
and
http://www.mediafire.com/?45u0obd6pjj5twp
(Do not extract this file only the others)
and this
http://androidforums.com/attachment...ery-optimus-one-p500-thunderg-flash_image.zip and extract both of them into folders.
(thanks to getitnowmarketing for guidance at this point)
Next do one of the following two methods:
METHOD A(EASIER):
8)Download & install:
Google Chrome to phone(PC Google Chrome extension)
Google Chrome to phone(Phone app)
Terminal Emulator (Phone app)
9)Synchronize your Google account in Chrome to Phone(browser extension and phone app) and make a test by sending something to your phone(link,text).Make sure it's working.
10)After that open Terminal Emulator and type "su"(without quotes) and click yes when it's asking you for Superuser permission."#" will appear.
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
11)From the commands list below copy every line (except red one) one by one and send it to phone.On phone paste all commands one by one,as you send them from Chrome, in Terminal Emulator.
Code:
mount -o remount,rw -t yaffs2 /dev/block/mtdblock1 /system
cat /sdcard/flash_image > /system/bin/flash_image
chmod 755 /system/bin/flash_image
mv /system/etc/install-recovery.sh /system/etc/install-recovery.sh.bak
[COLOR="Red"][U](if it shouts at you here saying not found or something,ignore it)[/U][/COLOR]
mount -o remount,ro -t yaffs2 /dev/block/mtdblock1 /system
flash_image recovery /sdcard/recovery-RA-GNM-thunderg-1.1.0.img
reboot recovery
12)Wait a bit and your mobile/phone will turn off, hold in the down volume key and the home key. Keep them held in for a bit when the LG logo comes up.
Skip to step 16!
OR:
METHOD B
8) Now download this: http://dl.google.com/android/android-sdk_r09-windows.zip (windows) or http://dl.google.com/android/android-sdk_r09-linux_x86.tgz (linux) ,extract and install it.
9) Copy(with mass storage mode on) the FILES (and the one zip file that was downloaded from mediafire--> the other two things copied accross should not be zip files but instead individual files that have been extracted. ) to your SD card (not in any folder or anything, just in the main folder that opens when you open your SD card on your computer).
10) Turn off mass storage mode on your mobile (pull down the notification bar and click where it says USB Connected and make sure it is off).
11) Next go Settings>Applications>Development>Tick USB debugging (make sure it is on).
12) Next, on your computer press windows key + r, type cmd. Then type
cd <follwed by the address of the platform-tools folder in the sdk folder>
For example mine was (remember all lowercase):
c:\downloads\android-sdk_r08-windows\android-sdk-windows\platform-tools
so i typed :
cd c:\downloads\android-sdk_r08-windows\android-sdk-windows\platform-tools
13) A whole lot of writing should come up and stuff in the box you typing in (cmd prompt). Next type adb shell and then the word su. Your phone should ask if it should allow permission for super user, select allow or grant access or whatever it says on your phone.
14) Making progress. Next copy the following lines and go back into cmd prompt and right click in it and select paste. Do one line at a time into cmd prompt.
15)
Code:
mount -o remount,rw -t yaffs2 /dev/block/mtdblock1 /system
cat /sdcard/flash_image > /system/bin/flash_image
chmod 755 /system/bin/flash_image
mv /system/etc/install-recovery.sh /system/etc/install-recovery.sh.bak
[B][U](if it shouts at you here saying not found or something,ignore it)[/U][/B]
mount -o remount,ro -t yaffs2 /dev/block/mtdblock1 /system
flash_image recovery /sdcard/recovery-RA-GNM-thunderg-1.1.0.img
reboot recovery
Wait a bit and your mobile/phone will turn off, hold in the down volume key and the home key. Keep them held in for a bit when the LG logo comes up.
16) You may back up if you want at this point by going to backup/restore (scroll using volume key and select it using the key on the very left of your phone at the bottom in the front). Choose nandroid backup and let it do its business).
17) Next get back to the mainscreen and select flash zip from sdcard. Select signed_kernal.zip and choose to let it flash. Let it do its business, go to the mainscreen, click reboot system now and you done. Your phone should restart happily with a much less cpu intensive touch screen!
hope this guide helps someone who had the same troubles as me.
Feel free to inform me of anything I may of left out

good work but all the commands can be entered using terminal emulator on phone itself..

---

thanks
I would much rather just use my pc to type the commands cause I can copy paste them nicely and I trust my pc more

If someone types that out I'll add it in (from getting the addon to accessing the terminal).

You can update first post if you like it!

Nice...
What about WifiKeyboard? With this tool you can write on phone with keyboard on your PC. Also can be used for SMSs, emails, and so on.

---

even better and more easy to use copy/paste for emulator.

---

It works
Thank u for the tutorial. It really worked fine, using the wireless keyboard. 10x for the help and effort u put in this.

---

thanks for this tutorial.. it helped me a lot..

---

Actually I found easier with the sdk and windows dos terminal, but whatever ^^, this is a great guide, should have seen before

---

So are you sure this doesn't work in 2.2.1?

---

hey i was just wondering... since lg will be releasing gingerbread for the optimus one(p500), is there a way to be able to do this in the future with this setup? or have we given up all future updates from lg or otherwise for this custom kernel??

---

also i just got an error message when i copied in the first part of the terminal part. I comes up "cannot create /system/bin/flash_image: read-only file system"
Need help!!!
Edit: i found somewhere you had to type in the "mount" line before it all... and it seemed to have worked, hope i didn't break something :s
Edit 2: now i've run into another problem as your instructions seem to skip steps and information towards the end. this line in particaular:
17) Next get back to the mainscreen and select flash zip from sdcard. Select signed_kernal.zip and choose to let it flash. Let it do its business, go to the mainscreen, click reboot system now and you done. Your phone should restart happily with a much less cpu intensive touch screen!
Select flash zip? There is no flash zip anywhere mentioned besides here. could you please clarify or could anyone tell me what he means as im stuck on this part

I can`t find the Google Chrome to Phone (phone app) in the market, can anyone help me with it?
And of course in the pc market, my network provider won`t let me install it.
L.E.: finally i`ve found the app. Flashed the kernel, works like a charm. Thank you.
