If anyone happens to face the lines in TWRP (white blurry screen), reboot, when in TWRP goto Settings, Display and turn off screen timeout.

Fixed it for me.

You were in Droidboot mode. From there you could also boot TWRP just type “fastboot flash recovery recovery.img” then select recovery with the volume keys and accept with power. <– Did that after fixing my BIOS issue.

You have to either reflash the BIOS or contact @Jonathan to let his BIOS reset too work it’s magic 🙂

They told me, they don’t have the sources via E-Mail.

I think I know why:

they bought the dual Boot UEFI Windows10+Android as a complete solution from Insyde. Thats why they don’t share it.
How do I know that? Well, Chuwi would’t include that fancy intel Animation on boot. Neither would they include Intel factory test .apks. Most cheap phones/tablets used to have the plain “ANDROID” on bootup. It’s also worth mentioning, that they somehow interface with the UEFI for Wifi. Chuwi changed the Wifi chip in the Hi8 recently. And newer models just use a newer BIOS to incorporate the change.

I sent Insyde an E-Mail, if they grant me access to their developer site, even though I don’t want to build and sell my own Tablet.

Let’s see, how they respond.

With root, you can lower the screen resolution on android 😉

Might be worth a shot for gaming.

But when watching Youtube I want my 1080p 😀

Hast du das Ladekabel verloren?

Wenn du es noch hast, aber es defekt ist, poste mal ein Bild vom Label. Dann kann ich dir wahrscheinlich helfen. 🙂

<hr />

Did you loose your charger?

If not, please post a picture of the label. Then I can probably help you 🙂

There you go.

Nah, I just opened the UEFI tool again, moved the shell all the way to the bottom and rebooted. Works now 🙂

I don’t judge the fact, that unstable and dangerous software is not available to somebody who stupidly bricked their tablet 😛

[Tschuuuls]

Thanks a lot @Jonathan, fixed the USB issue. Now I just have to fix the boot Order, so that it boots into Windows/Android and not into the shell.

You are awesome.

For the record some logs (i hate threads without solutions) 😀

OK, here’s the modified util. I’m guessing you know what to do with it, if not let me know.

Better tell me, before I brick the thing even harder 😀

My guess is putting it on the sdcard, chmod 777, call it and redirect the output to a txt file?

It didn’t create a “Vi10_SetupFixLogs” directory.
Just the gv_gen that I created.

EDIT: That’s what I did in shell:

C:\Users\User\Downloads\TWRP_Chuwi_Hi8>adb shell
~ # [6ncd /external sd
cd /external sd
/sbin/sh: cd: can’t cd to /external
~ # [6ncd /external_sd
cd /external_sd
/external_sd # [6nls
ls
/external_sd # [6nmkdir gv_gen
mkdir gv_gen
/external_sd # [6ncd gv_gen
cd gv_gen
/external_sd/gv_gen # [6n/sbin/gv > log.txt
/sbin/gv > log.txt

ls

OK, just keep in mind that I can’t test the TWRP image myself and I might need to tweak it a bit to get things running properly

No worries 😛 Been using custom Roms since Android 2.2, I am used to things that need some tweaking 😀

 

EDIT: Had to rename the uefi_var.bin to *.txt, the Froum complained…

I’m just looking at your other post, you said: “screwed with OTG Settings, disabled power set OTG to PCI” Is that all you changed? On the Vi10 those settings don’t disable USB…

Yeah, I just disabled the splash screen to show the UEFI version and set boot to legacy fist (was set to UEFI first). But it still booted at this point.
USB got disabled when I changed USB to PCI AND disabled VCC to USB. I tried supplying power to my keyboard with an powered hub. No dice 🙁

Will get you the files in a couple of minutes. Stand by.

In Option 1 I would modify the internal partition that tells the Tablet what to boot? Since I can’t boot of the USB flash drive chuwi is suggesting.

I’d choose Option 2. I downloaded the img just now. Which files do I have to pull?
