I bought a non working Samsung Galaxy Tab 3 7.0 tablet in hopes of fixing it.
Specs at
http://www.gsmarena.com/samsung_galaxy_tab_3_7_0-5422.phpSymptoms
- no display on screen
- nothing ever shows up on the screen (no text or android symbol/robot)
- no sound
- backlight is on and stays on
- draws about 0.9A when plugged into AC adapter
- not recognized as a USB device in Windows or Linux
What I have done so far
- hard reset (holding power on/off and volume button) does not change behaviour
- have removed and reconnected the battery (left it out for several hours)
- removed and reseated all cables
My guess is that is "hard bricked" and requires some sort of jtag programming? If yes, I have no such tools. Anyone else see this or have other ideas?
