Hello again,

I have to say i'm sorry if my message seemed like an attack to you.

It's just there are ppl like me that they are not experts and we try to follow the instructions anybody give but sometimes not everything goes as planned. So since you do want to help be a bit patient with us (stupid in these kind of things).

Finally I have to thank you becouse reseting my factory settings like you said fixed the problem and now my phone works great.

Glad to hear that.

Because of different phone, computer, and understanding. This is not math 2+2=4. Hardware may fail; then 2+2=0.

Worked Good for me! Thanks! B)

I had uninstalled some of the google apps and got lots of errors because of it - the steps to flash worked and so did root method.

Because of the errors the flash failed first time.

I did these additional steps and flash worked:

-Remove SD card and Sim

-Do a factory reset before starting the flash

-Flash as per instruction above

-Format the SD card after flash (Do a backup copy if you must)

All good now and lessons learned as far as not uninstalling too many components

RESERVED FOR LATER USES.

I have currently installed the baltic black rom on my phone (as this was the one recommended to me), and all appears to be working fine.

But just wondered has anyone tried any of the other roms ??? EG the carphone ware house open uk rom. I ask cause this is the ideal rom for my phone being that I bought it from there and would like to have it set up to its optimal settings. I have noticed using baltic it can have some very minor issues in that it doesn't always default to my location being in england, which can be a bit of a pain.

Any opinions on this would be much appreciate, I realise the roms are all from LG so in all likely hood will be ok, just don't want to reflash it only to find it doesn't work, when the phone is running alright now.

True.. but they're not that bad.

I've got the Carphone Warehouse ROM.

Extras are the usual shazam, foursquare, Sims etc...

I've only binned about 6 of them but left most of the other stuff on like Google Maps and the extras.

If you use Apps2SD for all your own stuff it doesnt really matter, I;ve got 101 apps + factory crap and the phone still has loads of space and my SD card has 800Mb spare for apps!!! (3MB in music on the other partition...)

Hello everyone.

Everything went well .... I'm happy ..... ;)

The steps I followed are:

Modified no paranoia

1 .- Disable i remove the microSD and SIM.

2 .- Backup of personal data.

3 .- Hard reset.

4 .- Disable the device from windows "virtual modem LGE. "

5 .- Follow the steps in the first post of iloveg point by point.

Everything was perfect ....

I installed the rom is Europe Open V20B http://csmg.lgmobile.com:9002/swdata/WEBSW..._00/V20B_00.kdz

Works fine ... :D

Note for the impatient: ;)

Attention Phone restarts 1 time only ... NO TOUCH .... until the KDZ get a message that says "FINISHED === ==="

1 .- Disable i remove the microSD and SIM.

This is completely Optional, i dont even have a clear idea why did u done that ;)

3 .- Hard reset.

And why did u done hard reset if you was going to get one when u was switching from 1.6 to 2.1 ?

People, stop being paranoid... :/ Its not like you are rewriting soft to your Nuclear Bombs launcher, so it might accidently fly off tu badword russia :)

Hi all,

Thanks to ILoveLG for such an interesting thread. This is my first Android phone so bare with me a little. I have GT540 with 1.6 and Arabic support (V10b). I used the LG upgrade tool to upgrade it to 2.1. The procedure went smooth and the upgrade was finished. Despite that, the phone still has Android 1.6. When I tried to update it again, it keeps saying that you have the latest version (V10c). I checked the phone, and it says android 1.6 and V10c.

I was thinking about using your method to reinstall the V10C ROM into it but I am afraid that the V10C linked to in here does not have arabic support. Has anyone used the V10C Rom, does it have arabic language?

Thanks all.

**** 30 Mins Later *****

I am getting Upgrade Error

WParam 100

LParam 2

Any ideas?

Greetings Dr.Alani, and welcome to MoDaCo forums.

The point is that Arabic dont have 2.1 yet, so that means u just updated to newer version of 1.6 ROM. From v10b to v10c, 2.1 Roms have v20 tag.

Neither theres a 2.1 ROM with Arabic language support, so i would suggest you to just flash it with Open Europe ROM. And when the Arabic one comes... simply just reflash it.

Have you fallowed all the points in the guide carefully? Im not familier with this error.

Thanks for the quick reply.

I followed it carefully. I also tried the Recovery mode too and this did not work either. I had an older LG phone "KM555" that I had the software for and updated some time ago. So, I though there might be some leftovers from the old drivers of the old LG phone. I installed the required stuff written in this thread on another computer that is fresh to LG phones with Windows XP and had the same error also. My previous trial was on a Vista computer.

Anyway, the error did not ruin the phones existing ROM so it can still work.

But you know I can not feel so satisfied until I tickle the 2.1 version. Regarding the arabic support, I need it to read SMS and some webpages like facebook pages of many of my friends. So, is my will to upgrade stronger than the need to arabic support? YESSSS.

I will keep trying to figure out what is the problem.

Since I am new to this, does rooting have to do anything with the update? Do I have to do something else on the phone?
