    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.

    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…

    Generaly I find the level of technical competence of users on this board is very high, it’s nice to deal with people who know what they’re doing 🙂

    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?

    Thanks, I didn’t think of the Forum detecting bin files….

    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
    /external_sd/gv_gen # [6nls
    ls
    acpi_var.bin
    log.txt
    uefi_var.bin
    /external_sd/gv_gen # [6n

    Can you please run /sbin/ChuwiSetupFixer and redirect the output to a file instead?

    There you go!

    C:\Users\User\Downloads\TWRP_Chuwi_Hi8>adb shell
    ~ # [6ncd /external_sd/
    cd /external_sd/
    /external_sd # [6nls
    ls
    System Volume Information
    gv_gen
    /external_sd # [6n/sbin/ChuwiSetupFixer > stuff.txt
    /sbin/ChuwiSetupFixer > stuff.txt
    /external_sd # [6nls
    ls
    System Volume Information
    gv_gen
    stuff.txt
    /external_sd # [6n

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

    EDIT: Removed link to modified utility (it needs more testing before it can be made permanently available).

    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?

    You got it, except I doubt the SD card will take the 777. I’d move it to /data/something or /sbin.

    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) 😀

    C:\Users\User\Downloads\TWRP_Chuwi_Hi8>adb push C:\Users\User\Downloads\ChuwiSetupFixer /sbin/
    3652 KB/s (370340 bytes in 0.099s)

    C:\Users\User\Downloads\TWRP_Chuwi_Hi8>adb shell
    ~ # [6ncd /sbin/
    cd /sbin/
    /sbin # [6nchmod 777 ChuwiSetupFixer
    chmod 777 ChuwiSetupFixer
    /sbin # [6ncd /external_SD/
    cd /external_SD/
    /sbin/sh: cd: can’t cd to /external_SD/
    /sbin # [6ncd /
    cd /
    ~ # [6ncd /external_sd
    cd /external_sd
    /external_sd # [6n/sbin/ChuwiSetupFixer > pleaseWork.txt
    /sbin/ChuwiSetupFixer > pleaseWork.txt
    /external_sd # [6nexit
    exit

    You’re welcome, I’m glad I could help.

    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).

    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 😛

    Can you post a link to that tool please? Sounds fun 🙂
