Can anyone fix the Tab 10C Pro only boot to the fastboot?

[Eternalcat]

I'm trying to install some custom recovery for my Tab 10c Pro,but when I flash the recoevry to my devices,It can't boot to system or recovery. Whin I reboot, it will boot to fastboot.

First, I tried to flash the offical recovery from my backup, it's not work.

And then I tried to flash the full update from 9008(EDL),I flashed every img except those img in the dynamic partitions, and I use an Android image tool to make an super.img to flash the odm,product,system,system_ext and vendor.
But it stell boot to the fastboot.

So now I can only boot to the EDL and the fastboot, I don't know what's wrong.
Can anyone help?

PS:The Boox OS Ver should be 4.0 beta,and I trying to flash the newest version. I can't download the old beta Ver.

(Sorry for my poor English)

PPS:The Tab 10C Pro is the Tab Ultra C Pro's Chinese Version, there's recovery can exchange,But I failed to flash the Ultra C Pro's system to my 10 C Pro. So I stell use Chinese's Boox OS

and I can't get HWID, I try to use edl, but I get this:
PS D:\Tab10CPro> .\edl.exe /l000a50e10029003c_ec70ff124179a138_fhprg.bin
Found EDL 9008
Could not open device
PS D:\Tab10CPro> .\edl.exe /l
Found EDL 9008
Could not open device

I can use other tools to load a loader to flash img,Am I wrong?

The Qualcomm virtual COM port driver that you installed is monopolizing the device.
Using my edl.exe you just use a simple WinUsb driver installed by Zadig.
See the instructions.

Is your goal to have global instead of Chinese software?

OK,I'll try Zadig

If I can have an global instead,I hope to install global version. My phone is trying to check every app whin install them. I'm worried that my pad do the same, too.

My first goal is fix it, but since now my pad can't boot now, I hope try global instead first. Can you help me? I will cooperate with you.

Have you found a working loader for tab10c pro?

[Renate]

The Chinese Tab10CPro is still on 3.5.4
The global TabUltraCPro has full 4.0.2 and a 4.0.2 update.

Are you dead sure that the two models are the same hardware?

Your first step is get the HWID. You get that by running an EDL client without specifying a Firehose loader.

Can I join in? I have a tab10c pro and trying to make it into tab ultra C pro too. Here is adb returns when i used edl.exe /l

Found EDL 9008, handshaking... version 2.1

Yeah, it's the same one, using snap 855, 6gb of ram and 128gb storage. and my tab10c pro is on 4.0 since March through incremental update

I think so, I can see the 4.0.3 from OTA. And I must to use the data.boox.com to get the newer version, the data.onyx-international.cn only gives me an 3.5.4

The information link is this: https://data.boox.com/api/firmware/u...erprint":""%7D

And the download link is this :http://firmware.boox.com/3a226e34db1...e5d/update.upx

I see someone already running EDL without loader, I hope that's right. If you need, I'll run it again.

That is the right Firehose loader for this.
I've updated: https://www.temblast.com/ref/onyxldr.htm

I need to make a custom recovery for this.
I've not had any luck making the screen work on BSR devices, but it should work (as a recovery without the screen).
Give me some time to make this.
