Charging issue
I doubt anyone will be able to help, but after unlocking nand, whenever I plug in my charger and then unplug it, it will always show as charging. Has anyone else had this issue?

Recovery
One more thing, how necessary is the final step where you flash the recovery.img? That's where my problem starts. Once I do that and plug in any charger, the phone will always show as charging even after I unplug it. Can I skip that step and do a nandroid restore from there? I'm really sick of staring at an orange led light because my phone thinks its charging. I've followed the steps to the letter and I always have the same problem.

When I try to flash PC36IMG.zip I get stuck. I have downloaded the file several times using multiple browsers and have even downloaded it using my phone and placed it in the root of the sd card with the same result. Here is the log that is generated when trying to load the image:
SD Checking...
Loading...[PC36DIAG.zip]
No image!
Loading...[PC36DIAG.nbh]
No image or wrong image!
Loading...[PC36IMG.zip]
No image!
Loading...[PC36.IMG.nbh]
No image or wrong image!

Sumbody told me to try a different sd card and it still dont work.

Can someone please explain to me what the lines of code:

cat /sdcard/flash_image > /data/flash_image
chmod 755 /data/flash_image
/data/flash_image misc /sdcard/mtd-eng.img

actually do??

Knowledge of this would be really helpful. Thanks in advance.

Boot Loop / Can't mount sdcard
So I totally made a stupid mistake when starting Part 2 of the toast root method. Hoping maybe you guys can help me.

I failed to rename the PC36IMG-root.zip back to PC36IMG.zip so after running the nand backup and completing the steps regarding flash_image and mtd-eng I rebooted the phone and it's not finding PC36IMG.zip (because its still named PC36IMG-root.zip

I cannot mount or gain access to the sdcard through shell or windows file explorer. The phone is stuck in a boot loop and the only way I can stop it is to take the battery out and hard boot into the recovery/volumedown+power bootloader.

Any help would be appreciated.

Do you have a card reader? That should work.

Edit: Or maybe you could boot into recovery like you did in step 1 and rename it via ADB?


Yet another edit: You do realize Part 2 uses a different PC36IMG.zip, right? You don't want to name the original one back to PC36IMG.zip.

I'm bored here at work, so I'll take a wild-ass guess. The cat command somehow moves or transforms flash_image from the SD card to the data folder on the phone. chmod, from what I've been able to decipher, changes the permissions on flash_image. Then, the last line uses the newly modified flash_image file (is it some kind of utility or something?) to do something or other with the mtd-eng.img. I'm an old command line DOS guy trying like hell to learn more about linux and android, but damn, it's not coming easy.
