Hi there.

I'm having a little trouble with my Optimus, I have upgraded to 2.1 (Romanian) and rooted (with 1 click) and installed apps2sd (with the last option apps and cache).
I have a 4GB microsd installed in the phone gaved 700 MB for apps2sd.

The issue that I have is that the phone freezes every time I use it for anything even if it is to check the weather (stays frozen for abou 30s every time). If I restart the phone it gives me an error that android.phone has stopped.

Any advice?

Thanks in advance, and a happy new year!!!



choose 1st option, standard app2sd and no problem.

What ROM did you flash?
Does it have something called SlideME instead of the market?

Two questions on the original instructions of this thread:

2. How to root my 2.1 device ?
- Download 1click root for GT540
- Excract zip file
- [...]
Launch root.bat from extracted folder.

Do I extract the files to and run root.bat from my PC or the SDcard of my phone?

3. How to Install Apps2SD to my 2.1 device ?
- Download autorootapp2sd.zip
- Download App2sd_guide_GT540.pdf
- Read App2sd_guide_GT540.pdf for further instructions. Guide have pictures in it.

Must my phone be rooted in order to install Apps2SD or can I skip the step on "How to root my 2.1 device"?

Thanks for any insight you can provide!

I tried running root.bat from my PC but that didn't work. I think it's because the LG modem drivers are not installed correctly. They are a pain!

I ran the "LGMobile update" program and selected "install USB Driver", but that doesn't seem to work. My device manager (Windows 7) lists four "Other Devices" (2x LGSIMODEM01 and 2x LGSIMODEM02) whose status says "The drivers for this device are not installed. (Code 28)". "Update Driver" doesn't help and when I delete the devices, they just come back after i "scan for hardware changes". BTW: I recently installed a new main-board, CPU and RAM. Everything else on my PC works fine. Please help me get these f***ng USB drivers installed.

GT540/GT540 Swift/Swift/GT540GO/GT540 Optimus/Optimus All of these phones are same, they are just called differently in different countries.

Download and install any of the ROM's you like, it dosnt matter... if LG Update software shows theres an update, do it, dont ever worrie about it.

Logically this autorootapp2sd script redirects the /data/app and the dalvik-cache folders into the ext2 partition such that to the 2.1 system there does not appear to be app2sd, but the memory of the data/app folder is increased.

Hi I'm trying to root my lg gt540. i'm running on 2.1.
i've tried the link in this thread to do it but when i download the file the only option i get is dimiss, no open.
i've also tried z4root, this seems to start rooting but then just exits z4root and goes back to my menu page.

any ideas where i'm going wrong? i have usg debugging ticked and also unknown apps ticked.

thanks
