Note (2018) fastboot problem

[ch3mn3y]

Hi,
I'm looking for Woking fastboot driver for (first) Note and some help with getting fastboot to work.
I got ADB working, but after I use "ADB reboot bootloader" it doesn't reboot to Onyx logo, but freezes and it seems to be stuck in rockusb mode not fastbbot as it should...

Any idea?

I just got this device. It's used and has 3.1 firmware installed (still no access to 3.2.1).

First you have to see what you've got:
I always recommend this utility:

Ok, it all comes out a bit technical, but you can see what you're dealing with.
When you plug in/unplug your device you'll see what appears/disappears.
Click on it and look at the right side. Do you see down a bit:

Interface Descriptor:
bInterfaceNumber:     0x00
bAlternateSetting:    0x00
bNumEndpoints:        0x02
bInterfaceClass:      0xFF
bInterfaceSubClass:   0x42
bInterfaceProtocol:   0x03

Then you've got fastboot, you might need a driver.
The easiest one to install is "Zadig":

Then you might need the fastboot executable itself, just search "minimal fastboot".

Dunno why, but "adb reboot bootloader" gives me different Interface that You had... So it mans that my device may not have Fastboot access? Nooo ;(

Interface Descriptor:
bInterfaceNumber:     0x00
bAlternateSetting:    0x00
bNumEndpoints:        0x02
bInterfaceClass:      0xFF
bInterfaceSubClass:   0x06
bInterfaceProtocol:   0x05

Wanted to edit previous post, but I cannot....

Just tried booting to recovery and it went fine. But rebooting from recovery to bootoader gives me same Interface like adbing to bootloader...

No, that's not fastboot or ADB or UMS or...
Sorry, could you give me the VID/PID (idVendor, idProduct) at the top of all that?
I think it's some kind of Rockchip interface.

Thanks for helping me to figure that out.

Here are this two ids:

idVendor:           0x2207
idProduct:          0x320A

Here you go:
Fuzhou Rockchip Electronics Company - RK3288 in Mask ROM mode

Now, let me share with you everything that I know about Rockchip:

Anyway, what you've got is a very low-level "rescue" type interface.
It's the equivalent of Qualcomm EDL, but entirely different.
Maybe you should search "Rockchip tool"?

Thanks, that worked! Unfortunatelly kernel with MAGISK 23 didn't boot, so either I have to try older versions, go with Kingroot and SuperSUme or just forget about root...
