My N2 board problem -- maybe about to die

Unread post by moutazsalem » Mon Apr 15, 2019 7:39 am

Hello,

i received my N2 board (4GB Model), then installed Android 9, it was working fine on my PC monitor as well as the TV.
turned it off using Android UI, after a couple of hours, i turned it on again by unplugging the power jack and inserting it back.

then i noticed that the red led is not turning on, so i thought there might be power problem, but right then i noticed that the blue led started flashing (still the red led is off) and no signal on the TV.
i unplugged it from the TV and connected to to my PC (still no red led, only blue blinking) and i was able to get a signal on my PC screen, then i tried to use my keyboard (which was working perfectly) but no power signal on the keyboard.

i have tried all 4 USBs, none worked, then i switched to SPI mode and i could see petitboot but again no power on the 4 USBs.
note that i use the power adapter that came with the N2

can you please help?

@moutazsalem, could you try to run lsusb when ODROID boot and if you can run Android terminal?
Which version of Android 9 is installed?

Before we decide whether you need RMA, could you please test one more thing on your end for me?
I've sent you a PM and sorry for the inconvenience...

Since we've done some work in order to indicate the problem for sure before RMA and it does not help to make your ODROID-N2 work, please drop an email to odroid at hardkernel dot com with the link of this thread and any proof you purchase from Hardkernel. I am going to help to proceed when your request is registered.

Thank you.
