It seems like everyday in this forum there are about 5 new threads of people "stuck in a bootloop" or "stuck on Google screen." The majority of these people don't know the difference between adb and fastboot or bootloader and recovery.
I bought the G1 on launch and there weren't tool kits. We had to use telnet and command prompt to do everything manually. I knew nothing about linux or coding, but I followed instructions and learned what was happening when I entered these commands. Through owning the G1 and then moving on to the Nexus One I don't remember seeing so many threads about people "soft bricking" their device. I think the reason for this is the tool kits and other scripts that make it almost too easy to unlock and root your phone. While I respect the people who write these scripts (and I think they do serve a purpose in some situations) I think it's causing more harm than good.
The people who are using these scripts aren't learning what is actually happening when they press 1 on their keyboard. Boom, their phone is unlocked, su-binaries and cwm recovery installed. Then, they flash a rom without creating a nandroid. What happens if something goes wrong and they didn't place any safety nets to help them? They post a thread saying their phone is bricked. People take time out of their day to help these people out, but since the user doesn't understand what the helper is talking about, they can't fix it.
Just last weekend I spent 30 minutes replying to a PM with step by step instructions how to flash stock images and including links to files and resources. The person replied back. Instead of fixing his phone himself, he said he "claimed his phone as stolen and will be getting sent a new one lol". WTF?! Not only is that morally wrong, it's also insurance fraud. And we wonder why carriers and OEM's are trying as hard as they can to lock down non-nexus phones.
Please, take the time to learn how to get yourself out of a mess before you are in a mess.
