So I have problem with a device (Galaxy Note 10 Exynos) SM-N970F stuck in EUB mode - pops up in device manager for 2-3s.
Phone connects and disconnects as Exynos 9820.
If I hold power button it stays connected for 6-7s and then it disconnects.
I first tried doing the hardware TP method to remove FRP and it didnt work.
Then I put the device together and I tried the software TP.
Phone is stuck in EUB mode.
I even charged the battery with charging board to eliminate that as a culprit. 4.18V/4.35V
Tried all the ports on my windows machine and a few cables.
I tried Software TP ON/OFF multiple times to kick it out from EUB but that didnt help.
Tried hardware TP again multiple times.
If it cant be unlocked can I unbrick it at least?
