Will the phone power on at all if not plugged in? If not, it's likely a brick - spare parts - and I wouldn't pay more than ~$80 (bearing in mind that I'm in a position where "spare parts" are useful). Switching the battery with one that you know to be charged would be a simple way to be sure.

Error 1 is hardware problem 100%.
I wish you good luck trying to restore or repair this device.
As of right now i have figure it out how to fix Error 1 problem but for rest of you guys with you engineering skills and learn how to read schematic.
Just in case give you heads up: DO NOT TOUCH shield over Baseband IC and/or don't think removing or re-balling Daseband IC.
Hint: It is Baseband circuit issue.
