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.
August 18, 2016 at 7:33 pm #47269OK, 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…

From the log I see that gv got some usefull stuff, where is my uefi_var.bin file and the log files from /external_sd/Vi10_SetupFixLogs please?
August 18, 2016 at 7:47 pm #47274Thanks, I didn’t think of the Forum detecting bin files….
August 18, 2016 at 7:53 pm #47275It 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

EDIT: Removed link to modified utility (it needs more testing before it can be made permanently available).
August 18, 2016 at 8:34 pm #47286OK, 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?
August 18, 2016 at 8:37 pm #47287You got it, except I doubt the SD card will take the 777. I’d move it to /data/something or /sbin.
August 18, 2016 at 8:47 pm #47289Thanks 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) 😀

Thanks for the log, although I already knew what it’d be because before making these utils available I test them on the data provided 😉
BTW I’m afraid I’ve screwed up your solution a bit by taking down the links. Until I can get more data on the Hi8 I’ll make the tools available on a case by case basis, it is possible to completely brick by setting one byte in setup incorrectly.
If you can’t sort the boot order out I’ll look into it tomorrow (or you could just bring out the big guns and flash BIOS).
August 18, 2016 at 9:21 pm #47293Nah, 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 😛
August 18, 2016 at 9:26 pm #47294Can you post a link to that tool please? Sounds fun 🙂
