So could anyone please tell me what does Fastboot do ? I installed my Eclair the same way but without Fastboot. Oh and i rooted my phone by some guy @ MoDaCo who created 1click root for Optimus.

when phone is off, you must press Volume Up + search Button + Power button, hold until show "fastboot mode" in your phone.

But why would you need to install fastboot?
I've flashed my GT540 several times and never had to use that and it roots just fine... so what is it for?

probs with KDZ_FW_UPD.exe

When running KDZ_FW_UPD.exe I've got problem when pressing "????????????????????????" Windows 7 x64 says it stops and that's it. Any ideas?

Same doing it with Windows XP SP3, error window: http :// dl.dropbox . com/u/3673477/error . JPG

Hi guys,

thanks for the tut, but I have few questions:

1. I flashed my phone with the first 2.1 rom that became available (V20B_00.kdz) and I am curious if this rom has fastboot already enabled since acording to the tut, I can skip step 3 if I have the baltic rom ( which i think was the first available).

2. What is step 5 for? Is this only for rooting the device?

3. Can I flash custom roms when they become available?

I would like to know this too. Does the Baltic 2.1 ROM have fastboot? If so how do i enter it. ?
