It's funny Jebba, I just had to do this again, and referred to the above link in the OP, and was like what the?? I found it though on the page. Almost panicked. Thanks for your efforts in this regard. I woudl consider this to be a crucial article for this phone. (Had mine 2 star brick again after trying to free up some rootfs space... good old r&d mode worked like a champ, although I really need to try the new method you posted. One question on that is whether the usb cable needs to be plugged into a computer, or if you can just plug a dead line in?)
* take battery out * insert USB cable (to boot device with charging boot reason) * insert battery & put back cover back * remove USB cable
