Updating t mobile g1

If everything went well, you are now a proud owner of a rooted G1. If the login fails, you might need to add your APN settings (use the Menu button to add a new APN profile).

If you don’t have a dataplan, it is also possible to use wifi to sign in. Before we can install a custom firmware we need to install the test sign keys.

If you don't want to wait for the over-the-air (OTA) update, RC33 can be downloaded now and you can be running Google Latitude in no time.

If you want to know where to download it and how to update the firmware on your G1, then follow along after the break!

You will be exploiting this flaw to enable ADB access and bring up the Settings menu, from which you can enable Wi Fi and activate the device. The ADP1 device is SIM unlocked, you said you have the Developer version of the G1.

You do not need to have a T-Mobile SIM, an AT&T SIM will work.

On your G1, everything you type on your keyboard is also being run in a hidden console with root permissions. Note: There are 2 ways to install the test keys, one is from the SD card and the other one is using ADB (from the android SDK).

I recommend using the SD card method because this is easier for non-developers.

The good news is that manually updating Android is a fairly simple process, the most difficult part being getting the new firmware version prior to receiving it OTA.

General instructions for updating to a new firmware (Outdated, new Jesusfreke firmwares are available) Its now time to install the custom firmware.

Currently there are three flavours available: If you are a normal user that wants to have root access, install RC8.

This update wont overwrite your OS (Bootloader and OS are two separate parts) If you want to revert to the original G1 bootloader, use the file attached in the XDA topic. If you are unfamiliar with the different types of firmwares, I recommend to use either the Official ADP firmware (1.5) from HTC or a customized firmware made by Jesusfreke.

If you’re upgrading to a new firmware, be sure to apply the radio update before the system/recovery image.

So I want to be going from rc7 to a custom rom, probably the Jesusfreke rc8 to start off with.
