How to Un-Brick Your Phone

(Method 1)

Ok so you're trying to put this really cool new custom ROM on your phone and then suddenly, your phone won't start up…well my friends, you have got yourself a bricked phone. The thing you worry about the entire time you're rooting, and flashing your phone, has now become reality. Well, fear no more, for I, CTDroidBeast have found a way to unbrick your device!

It's really easy. It's actually easier then rooting your phone, believe it or not.

Ok, you will need a new SD card, because I bet if you use the one out of your device your computer will not be able to read it. But if it does then HEY, you're in luck. You don't have to spend your money on a new SD card.

So let's get started.

Step 1: Turning Off Your Phone

Because you have a bricked phone, you can't just hold the power button. So if your phone is not already off then you're going to want to take out the battery.

Step 2: Preparing Our SD card

Take out your SD card and put it into an SD card reader or some type of other adapter so that we can view it from our computer. If you cannot view the SD card on your computer then you're going to need a new SD card.

Download DREAIMG-RC29.zip and unzip the file.

Reformat the SD card to FAT32 and copy the DREAIMG.nbh onto it.

Safely eject the SD card.

Put the SD card into your device.

Step 3: Wipe The Phone

Hold home and press the power button.

When you see the image of an ! mark, open your keyboard and press Alt + L if you cannot see any command options.

Do a factory reset by pressing Alt + W or just using the trackball.

When the reset is done, go ahead and hold the camera button and select the reboot system now option with your trackball.

Step 4: Flashing The Phone

Once the grey screen pops up (or the white screen if your phone was rooted with JesusFreke) it will ask you to hit a button to start installing the image…press that button. DO NOT DO ANYTHING TO STOP THIS PROCCESS. It will take about 8-12 minutes.

When the image has completed the installation (it will say completed), go ahead and press the green, red, and menu buttons at the same time. The phone will reboot.

And your done! Your phone is now unbricked!.

The G1 screen will hang there for a good minute or two, but be paticiant, it will boot. Now you have a choice. Try to hack your phone again, because you're in the correct state to have another go, or, you can stick with the official Android. Now if you choose to stick with the official Android, here's what you do.

Step 1: Upgrading to Android 1.0 RC33

Download the file signed-PLAT-RC33-from-RC30.zip

Rename the file to update.zip and copy it to your SD card

Reboot your phone into recovery mode. Power off the phone first and then hold down the Home key while powering it back on.

The recovery mode is finished loading when you see the ! mark inside the triangle. Press Alt + L to display the list of options.

Press Alt + S to flash the file update.zip.

Wait for the update to apply. Your phone may reboot during this process so be patient.

Press Home + Back if prompted to reboot your phone.

Step 2: Upgrading to Android 1.5 CRB43

Download the file signed-kila-ota-148830.de6a94ca.zip

Step 3: Upgrade to Android 1.5 CRC1
