Rebooting to bootloader freeze

[bingo619]

Hi,

Trying to root my NotePro V3.0, everything went fine except I could not get it into the bootloader mode, tried both adb command and recovery. What exactly does the bootloader look like?

Basically the UI freezes when I run adb reboot bootloader. Recovery freezes with a line "rebooting to bootloader".

Any ideas?

fastboot reboot

reboots your Note Pro. Was this your intention to ask?

There is no GUI at adb. It's just a terminal window on your PC.
Do you have a magisk patched bootimage?

No, I meant I could not even get it into bootloader/fastboot mode.

Yes, I do have the patched img. Just need to flash it in which i could not without the bootloader mode.

It doesn't look like anything, but you should be able to send commands. I'd suggest you wait like 30 seconds after `adb reboot bootloader`. Then the device should be in fastboot mode, but there is no indication on the device's screen. `fastboot devices` should see it though

It could be a missing driver problem. Device drivers for adb and fastboot are needed.

This is not a bug. Actually you are using a Rockchip device and it doesn't support fastboot command at all. If you want to dump anything to a rockchip device, you need to use RKDevTool. I wrote a guide on how to deal with the rockchip backup and restore in my medium article. Please feel free to take a look. In a nutshell you need to install rockchip driver and download the RKDevTool to flash boot.img onto your Note Pro.

If you want to try the magisk method please get a backup your boot.img in advance or you may get your device into an unbootable state. I got no luck on the Magisk method but I eventually got my device rooted.

That's not true. Most/all Rockchip devices have the rockusb mode, set to boot to that mode with reboot bootloader, so they use a different command for fastboot, reboot fastboot.
That said, you might as well use rockusb unless you're booting a boot image without flashing it.

Thanks a lot.

I got into fastboot by

adb reboot fastboot

Then follow the procedure at the bottom of link to Unlock your Device via Fastboot

update:

managed to flash the patched boot img. Now the NotePro can not boot into the system, can only boot to the System Recovery.

What should I do now?

There are several ways

1. Go your Note Pro into bootloader mode - I am not sure if you can find the option from the recovery menu. But you can get your Note Pro in the recovery mode by turning off your device, holding the home button and power button together. Just connect Note Pro with your PC and see run RKDevTool.
2. Flash the working boot.img
   • It would be lucky if you have a backup of your original boot.img, or
   • you can obtain the boot.img using the decryptBooxUpdateUpx. In a nutshell, you need to
     • Download the firmware from the official website
     • Use decryptBooxUpdateUpx to convert the .upx file into the .zip file
     • Get the boot.img from the .zip file.

Thanks.

I accidentially flash root.img to ox00000000, now it would not boot into the recovery nor system.

Anyone has got backups?

can anyone please dump a NotePro backup for me? Very frustrating.

Did you flash your boot.img using RKDevTool or fastboot?

I am using Nova and I guess it should be compactible as I am using the same Rockchip chip as Note Pro.

1. Download my dumped image. It contains 3 files.
2. Open RKDevTool (I am not sure if you still be able to use RKDevTool) and flash the following:
   1. uboot 0x2000
   2. misc 0x4000
   3. resource 0x6000
   I dumped my system and couldn't find the loader partition (0x0000) so I am not sure if my image solves your problem.

@winstonma Thank you very much.

I used fastboot to flash the patched img initially.

I have your files, did not work. Do you happen to have the loader and parameter starting from ox0000? I think I override them accidentally.

BTW, which rockchip are Nava and Note Pro using? Your partition config seems not matching of any of these from https://github.com/rockchip-linux/to...evTool_Release.

Thanks again.

No I used RKDumper and tried to dump the partitions in my device. But they don't have 0x0000. I guess 0x0000 is the LOADER partition if it is corrupted then I am afraid you won't be able to get back to the LOADER mode.
