First off, when ever you start to modify your device, always remember to make a Nandroid backup, and copy it to your desktop!! (enter bootloader, Alt+b then save the Nandroid folder on your SD to your desktop.)
That way, whenever to start switching ROMs are what not, and something goes wrong, you'll always be able to revert your phone back to it's last working condition. Doing this will save you from lots of frustrating nights.
I also recommend making a new backup everytime you change ROMs and saving all of them for two reasons. First, you will have all your apps and what not alreay there and not have to go through the trouble of finding and setting them up all over again, and Two, if you're like me and like to switch ROMs alot, it's alot easier to just fastboot a ROM than doing it through the bootloader. And like I said, everything is already there where you left it instead of what goes on when you Alt+w.
When your phone lags, or loops or you think it's gonna brick...as long as it powers on, you're Golden. Just power off. and fastboot.
Making your device "almost" brickproof
First, start the bootloader home+power
Once in the bootloader, press alt+b and wait for it to make your backup. Then reboot.
Power on, mount the phone via USB and get the Nandroid folder of your SD and copy it to your Desktop
Create a new folder called Android and put it in the root of your C:\
Copy the following from Nandroid folder to Android folder:
data.img, system.img, boot.img
Restoring your piece
Power on in fastboot (camera+power)
Plug in USB, but do not mount, just push the back key until it says fastboot
run CMD(Windows), or Gnome(Linux)
enter cd C:\Android *replace "C:\" with whatever drive you have your folder on
at C:\Android, enter:
fastboot flash system system.img after it says okay, enter
fastboot flash userdata data.img after it says okay, enter
fastboot flash boot boot.img after okay, enter
Then you WILL be back in the game!!
Well, I thought wiping solved the issue.. but this afternoon, we were watching a vid on youtube, and the screen froze... my battery wasnt low, there werent lots of things going on... it just froze... Now when I reboot, I get stuck on either the first or second splash screen... just neva know...
and when i plug it in to charge, I get a RED LED light, instead of the Orange that I am used to... WTF??? so what does a RED light mean?
I really dont wanna wipe it again just to start over and have this trouble all over again tomorrow...
nice post and thanks for the info but if you've read this thread at all it's for the actually bricked phones which were made so by upgrading to haykuro's new SPL. bootloader, recovery mode, safe mode, nothing will boot this phone past the G1 loading screen.
i'd kill to be in your place opposed to mine
I would bet the vast majority of bricked phones are windows only users. If its possible to do on Windows I would make that my priority if I was a dev. People that use Linux are generally tech savy enough to either also have a windows PC or be able to make it work through an emulator. Windows only people are generally lost when it comes to Linux. Just a little point to consider.
A JTAG interface generally means taking the phone apart, locating the test points on the circuit board, and then soldering a bunch of wires to those testpoints. If you're squeamish about installing linux on a PC and running a Linux program, JTAG probably isn't for you.
