can u upgrade from 2.1 to 2.2?? recently i upgraded to 2.1 via Modaco's one-step method..

 

[dongwan123]

For me when i get the fastboot mode and open CMD, the computer won't recognize the phone... after fastboot.exe -w it says < waiting for device > and for some reason the computer won't recognize it even though i installed the drivers that were provided on this website. When i connect my phone the install wizard comes up but it can't find the hardware for the phone. What do i do?

 

[wirsininkas]

Yeah you can, just follow the steps provided in the first post and you'll have 2.2 in no time! Just make sure you read the bug list and what does and doesn't work.

Are you sure you put the phone in fastboot mode by holding the camera button whilst powering on the phone, until the screen goes blank?

Ah, that's good, at least everything's sorted now

it was really nice of you..

 

[dudeman1996]

Thanks, I found this out myself and thought I'd tell other people about it because I doubt that LG will be releasing Froyo 2.2 anytime soon, so this would be pretty much the only way to get it!

LG won't...

 

[dudeman1996]

LG won't...

I know :\ And the worst part is, is that they've released other phones in the Optimus line that are running 2.2 and have near identical hardware specs, pretty much the only difference is the screen; yet they can't port it over to the GT540!

Well, It's not that LG is lazy... GT540's processor, ARMv6, can't handle Flash.. So, they can't update...

 

[dudeman1996]

But the other ones have the same 600MHz processor don't they..?

 

[Nirob]

But the other ones have the same 600MHz processor don't they..?

Yes, but they are not ARMv6, they are ARMv7 or higher...

 

[dudeman1996]

Yes, but they are not ARMv6, they are ARMv7 or higher...

Ah, I see, well CyanogenMod seems to work perfect on it haha..

 

[renstheripper]

I seem to have lost mobile data connectivity. Does anybody know if this is a radio baseband issue or know how it can be resolved?

Baseband version - AMSS53404003
Mobile network state - Disconnected

Has anybody encountered this issue and found a solution?

This happens to me every now and then, just reboot the phone, it worked for me!

Unfortunately a few reboots later and I am still having the same issue

EDIT: Fixed! Added APN and everything works.

Brilliant, sometimes it just takes a bit of searching through all the settings before you find the answer to your problems!

ya! but we won't ever get full Flash... :'(

 

[djpailo]

Does silverlight still work and presumably html5 will work fine?

Silverlight doesn't but HTML5 works well with a bit of lag

 

[dudeman1996]

I know but at least we get 2.2! I'd rather have 2.2 than 2.1 without flash

Quarx and ankuch from 4pda.ru are working on porting CyanogenMod 6.1 Android 2.2.1 to the LG GT540, it's available to download although it's still in beta stage so there are a few bugs in it.
Here's the list from the site saying what works and doesn't (I'll update this list as they do):
What's working: Wifi, GSM (Mobile Data), Camera (photo / video in 3GP), Bluetooth (receiving / sending files / HID), Video Codec (Hardware only H264), stereo audio to the headset, 3D accelerator, detectors, GPS / AGPS, navigate base stations, installing programs on a flash drive (Apps2SD).
What does not work: Fm-Radio, Camera (Video in H264/MP4), Codecs (XVID, DIVX)

Buglist:

Spoiler

1. If the flash drive, for whatever reason, does not mount, then through the ADB, give the command: "mount-t vfat-o utf8, umask = 000, rw / dev/block/mmcblk0p1 / sdcard" and then "Settings / Memory / SD-Connect card .
2. Posle use USB-drive, flash drive does not automatically mount: a solution to in paragraph 1, or simply restart the device.
3. Reboot in Recovery menu does not work.
4. Synchronise with PC Suite will not work
5. Adobe Flash Player does not work! only FlashLite works!

Make sure you follow the instructions exactly as they're written. As always, with flashing your phone, there's always the risk of bricking your phone. I'm not responsible for anything that happens to your phone because of flashing custom firmware. But I will do my best to try and help you with any problems you might encounter


To install this ROM you need to have fastboot enabled on your phone. If you have Android 1.6/2.1 installed from LG, then fastboot is not enabled. I will explain how to enable fastboot on your phone (this involves re-flashing/replacing your currently installed firmware):

KDZ Updater CarphoneWarehouse Unlocked.zip - A link to a zip archive with all the files needed to flash Android version 2.1 with fastboot (Carphone Warehouse Unlocked)

KDZ Updater Europe Open.zip - A link to a zip archive with all the files needed to flash Android version 2.1 with fastboot (Europe Open)

Download the version that best applies to you, if you live in the UK, I'd recommend you download the Carphone Warehouse Unlocked version, whereas if you live in Europe, I'd recommend the Europe Open version (simple right? )

Now, how to flash these versions; I'll explain in detail how to flash the ROM's from starting with backing up.

Instructions to install ROM with Fastboot:

Spoiler

1. Before you start, make sure you backup all your data by installing the z4root.1.3.0.apk file onto your phone, then open it and choose 'Permanent Root'. Your phone will root and reboot. Then go to the Market and install 'MyBackup Root', open it and do a backup of your apps and personal data (contacts, sms, call log etc.) Once this is done, go to Settings>SD Card and Phone Storage>Unmount SD Card, a notification in the notification bar should appear saying 'SD Card safe to remove'. Remove the battery cover and remove the SD card and store it in a safe place. Then continue to step 2.

2. Extract the .zip file you downloaded to your computer (e.g. your desktop). Open the folder and install MSXML 4.0 SP3 Parser (msxml.msi).

3. Once that has finished, install LGAndroidDriver_WHQL_ML_Ver1.0_All_Win7.exe which are the drivers so your computer will recognize your phone.

4. Next, open KDZ_FW_UPD.exe
(i) Change 'Type' to '3GQCT' *THIS IS A MUST, THE UPDATE WILL NOT WORK OTHERWISE AND YOU MAY BRICK YOUR PHONE*
(ii) Make sure 'PhoneMode' is set to 'DIAG'
(iii) Browse for the 'V20B_00+Fastboot.kdz' file.

5. Prepare the phone by enabling USB Debugging by going to Settings>Applications>Development>Enable USB Debugging and connect the phone to the computer via USB cable and wait for the drivers to install for the phone.

6. Click 'Launch software update' and do not use your computer until the update is complete. The update will take roughly 10-20 mins to complete.

Instructions to install CyanogenMod:

Spoiler

Once the update is complete, your phone will reboot, what you need to do is power off the phone and whilst the phone is off, press and hold the 'Camera' button all the way and power on the phone, make sure you hold the 'Camera' button. The phone will display the LG logo and disappear, then display a blank screen. The phone is now in fastboot mode!

Now you want to download this file: Flashing CyanogenMod.zip and extract it to a folder called 'Android' (without the quotes '') on the C: drive (you'll probably need to make this folder yourself.

1. Now open CMD with administrator privileges (Search for CMD in the start menu and right click on 'cmd' and click 'Run as Administrator' )

2. Connect the phone to your computer via USB cable and wait for the necessary drivers to install.

3. Then go back to the cmd window and type:

cd  C:\Android

(i) Then type:

fastboot.exe -w

(ii) Once that's completed, type:

fastboot.exe erase system

(iii) Once that's completed, type:

fastboot.exe flash system system.img

(iv) Once that's completed, type:

fastboot.exe flash boot boot.img

(v) Once that's completed, type:

fastboot.exe reboot

4. Your phone will now reboot with CyanogenMod 6.1.1 (Android 2.2.1). The first boot might take longer than a normal boot.

5. You can now re-insert your SD card and go to Settings>SD Card and Phone Storage>Mount SD Card

Enjoy!

The instructions for flashing both the firmware with fastboot and flashing CyanogenMod are included in the zip archives called 'Readme'. I'll update the links so that you'll always have the most up to date version of CyanogenMod available for download, note that if you choose to update your phone you will loose all your data including apps etc. so backup before you update
