The worst bootloop

[wihi48]

Model: GT-N7005

Problem: Switching on my phone result in the prompt before download mode followed by a restart and the same thing happens.

What I have done:

-changed battery

-reconnecting everything from the mother board

-use an external wire to power on the phone without battery

 

Wondering if motherboard is spoilt ??

 

Advices and help would be much appreciated.

Try to get into the boot loader and reset to factory settings

Use it as a paper weight perhaps?

When did the problem start occuring and did you root or install custom recovery/rom on that phone before?

I had the latest *cyanogenmod* ROM it was available (now lineage os) I have been using it and changed the battery recently (before that I was using wire to "splice" to switch on the phone. But besides that nothing else.) The phone then started to become wonky. Volume down button keeps spamming and I somehow could not charge my phone.
