Root Need help getting a new rom on my G1

[u2020bullet]

I know there's a guide stickied to the forum, but i cant use it since it only references the US and UK models of the G1, and my G1 is german. It is currently running Cyanogenmod (i have no idea which version) and it's incredibly slow and everything keeps crashing.
I am a complete beginner when it comes to rooting/flashing new roms to android based devices and i would really appreciate it if someone could help me step by step in flashing my G1 with a lite rom (has to have GPS).

You can use the guide for UK Dream, I've used it for my czech phone also, it means european version.
Check the version under Settings / About (Einstellungen /

My android version is 2.2.1
And here's some additional info:
Kernel version: 2.6.35.7-cyanogenmod
Mod version: CyanogenMod-6.1.0-RC1-DS
Build number: FRG83

It's not the last version, latest is 6.1.0-DS (not RC1, which is release candidate, test version).
Before continuing, make backup in Titanium backup (to be able to restore apps to different ROM)! I also recommend to make nandroid backup (follow second link).
If the apps or phone are crashing, it's not caused by ROM, but most probably by applications. If you want to keep Android 2.2, download the latest version and follow first link to install it. BUT because Android 2.2 needs more memory than Dream has, even with swap memory on sdcard Android 2.2 was pretty slow on my Dream, but it was still stable. If you update from your ROM to 6.1.0-DS, you don't need to wipe (reset) the phone, it's enough to clear Dalvik cache and all installed application and setting will be preserved.
If 6.1.0-DS is still too slow for you, I recommend to download older version (I've tested 4 and 5 also, both was fine and much faster on Dream), let's say Cyanogenmod 5. Go to first link, download the ROM (not the latest, but 5.0.8-DS for Dream), Google apps (Tiny version for Cyanogenmod 5), boot to recovery and follow the guide.
Be warned, that some application you're using might not work on Android 2.1 or 2.0!

Well, i've started backing apps up using Titanium backup and after that i'm gonna use nandroid
BTW, is it possible to get CM7 on the G1? or is that one even harder on the resources?

EDIT: Nvm, i just read they've discontinued support for the G1.
Are there any additional themse for Cyanogenmod 6? i can't seem to find anything on google...

EDIT2: Just finished flashing the rom and google apps. Booting up was a success, and it even kept most of my apps (including the launcher). Now i'm just gonna install the rest of my apps and then optimize the phone using this handy tutorial (used it before the flash and man the phone ran better than ever):
