I’ve noticed a lot of questions about people with bricked G1’s. The only problem is some people are saying that they’re getting stuck in boot loader. First of all let me tell you from experience. If you can even get to boot loader that means that your G1 is not bricked. It’s just frozen. Anytime your G1 is able to access anything its still salvageable. For anyone in this situation I suggest retracing your steps before you think you bricked and possibly loading another custom rom. Realize that if you decide to root your G1 in the first place, you’re taking a huge risk. These smart phones are nothing more than mini computers and just like a computer you can crash it. Unfortunately you can’t wipe the motherboard of a bricked G1.
Not to mention that these forums are so sketchy in their description of how you’re supposed to go about uploading custom ROMs and radios to you G1. If you’re not careful you’ll upload the wrong radio for your phone and you will defiantly end up with a, “Bricked G1.” By the way. To clarify; A bricked G1 is a G1 that is stuck on a particular screen. No matter how many times you take the battery out and put it back in, the same screen will come up. Even if you try to turn on the G1 in recovery mode, it will still pull up the same screen. So the term is true to the description. Something that’s only good for a paper weight. Someone may as well start collecting all the bricked G1’s, some mortar and build a house for the third little pig. Unless Google knows how to fix them which they won’t do because you voided your warranty when you rooted the phone in the first place before it bricked.
