I just got the Teclast M30 and I unlocked it. From fastboot I installed the Twrp but when I restarted in Twrp from "Fastboot", typing "fastboot boot twrp.img" it opens a page written "Orange State", "Your devices as been unlocked and can’t be trusted. " Your devices will boot in 5 seconds" and then opens up the screen full of blue lines. How can I fix it?

Ciao, anche io ho avuto lo stesso problema, fai una ricerca: "Orange state Fix" poi scarica il relativo zip ed installalo con TWRP.

Hi, thanks, my problem is that I have a blue striped screen and I don’t know how to get into Twrp. I can’t even get into "fastboot", the screen is always striped blue. When I try to type any fastboot command in cmd then it only shows "waiting for any device"
What can I do??

Ciao, se non ti si apre la TWRP vuol dire che quella che hai installata non è compatibile con il tuo tablet.
Che modello hai M30(????) ?
Non ho capito bene! Quando dici che " lo schermo è sempre a strisce blu" intendi quando entri in recovery mode?
Se è cosi spegni il tablet insistendo sul pulsante di spegnimento/accensione alla fine dovrebbe riaccendersi in Orange state.
Tieni presente che questo errore è dovuto allo sblocco del bootloader non alla TWRP.
Se vuoi puoi mandarmi un messaggio privato.

I restored it with "SP Flash Tool" but now I have a Chinese rom full of Chinese apps. None at a Global rom with gapps. I have an M5P4, I probably flashed a wrong Twrp. Now it’s unlocked.

m4p7 android 10

install the ADB drivers and you will need the android platform tools in a folder on your desktop

unlock the bootloader

flashed the 1.06 chinese firmware with SPFT (v5.2020)

booted to said firmware...made sure usb debugging was still on and oem unlock (not that it matters but also had to figure out how to change the language to english)
rebooted back to fast boot

flash twrp with fastboot (DON'T USE THIS ONE..ITS ****ED https://github.com/SDSkyKlouD/android_device_teclast_m30 --->USE THE RUSSIAN ONE https://4pda.ru/forum/index.php?showtopic=966087&st=240#entry91557876 )

boot to twrp

wiped system....data...user...cache....davilk.....I may have wiped vendor to....can't remember....if you have problems..you may need to reinstall the stock firmware again with SPFT...and start again....in this cased don't wipe vendor and leave the other random partitions alone (there is like 7 or 8 partitions total)

then I booted to fastboot (you won't have a os on the tablet at this point except twrp and fastboot) and flashed the phhusson AOSP 10 221 https://github.com/phhusson/treble_experimentations/releases

I then booted back to twrp and flashed the orange state fixer https://romprovider.com/download-orange-state-fixer-fix-orange-state/

then I went into twrps file manager and moved /system/lib/vndk-26/libstdc++.so to /vendor/lib/libstdc++.so

then I followed this ---> https://github.com/phhusson/treble_experimentations/issues/1305

Starrylight commented on May 10 •
Tried v216 and v215,
Teclast M20 booting does not finish.

But I tried this link,

adb root
adb remount
adb shell cp /system/lib/vndk-26/libstdc++.so /system/lib/vndk-sp-26/libstdc++.so

and used the "ld.config.26.txt" file in the comment link.

adb push ld.config.26.txt /system/lib/vndk-26/ld.config.26.txt
adb push ld.config.26.txt /system/etc/ld.config.26.txt

all I did was this part--> adb push ld.config.26.txt /system/etc/ld.config.26.txt
and then the tablet booted to android 10...the first time it boots...it resets itself automatically...then after that it booted normally...
I was getting some weird system service crashes so I just booted back to twrp and formatted the data partition and the user partition once more and then the errors went away

if you want I think you can flash magisk without a problem to

Please - publish your installation guide.
Would be nice to see how you solved this.
When I manage to install Android 10 on this tablet, I always get extreme battery drain.
Maybe you got better success.

Maybe you'll know.
Somehow, the kid has managed to get her M30 bricked. Absolutely dead, doesn't turn on, anything.
I'm trying to save it by trying to wipe it clean and start fresh.

With SP flash tool, I'm able to *start* a process, but I haven't managed to complete it, as the tablet disconnects.
I realized that while I'm holding the power key, it is being detected by the PC, when I release it I hear the "unplug" sound and whatever SPFT has been doing - stops.
Happens on 2 PCs, different cables and ports.

When holding power, obviously at some point it resets, so I can't follow a flash through.

Any ideas?

sounds like the power might be dead...try charging it for a few hours ...then try to boot to recovery

I had a similar thing
to get to recovery you hold the volume up and power button

I filmed it:
https://www.youtube.com/watch?v=rFs0lYqQeuE&feature=youtu.be

The tablet is being connected for the past few days, so running out of battery is crossed off the list.
My USB hub has a feature of lighting up a led whenever a port is active.
Button is pressed? There's the USB connect sound and the led lights.
I release the button? USB disconnects, led goes out.

I CAN start a flash while holding the power button, but after a few seconds the tablet restarts, breaking the flash.

By the way, no fastboot menu and no recovery. SPFT is able to start flashing up until the actual restart.

    Hey folks,
    I just built TWRP for Teclast M30 and it seems working correctly. Please try if you want.

    Download github.com/SDSkyKlouD/android_device_teclast_m30/releases
    Source github.com/SDSkyKlouD/android_device_teclast_m30
    Install Instruction github.com/SDSkyKlouD/android_device_teclast_m30/blob/master/README.md

    First, you have to unlock bootloader. Unlocking bootloader can be done with fastboot.
    Flash the img file using fastboot during fastboot mode:
    Code:
    $ fastboot flash recovery twrp~~.img
    After done flashing, reboot to recovery and TWRP will come up.

    If you have any questions, please mention/DM me on Twitter.


    - Extra info about GSI
    While Teclast M30 is released with Android 8.0 preinstalled, the device is Project Treble capable. You can check Treble checker apps if you doubt.
    So, GSIs can be installed. You can try ARM64 A-only images. I tried LineageOS GSI (Android 8.1), Havoc OS GSI (Android 9.0) and many GSIs listed on phhusson's GSI list, they're working well (except Android 9.0 GSIs, they have Bluetooth discovery issue). Android 10 GSIs are not working, since they're stay forever in booting logo.

    Scatter file you can get in the firmware from the first page. But I'm not sure enough if it can be used in case the firmware versions are different.

    It's OK to use the scatter file from firmware v1.02.
    Works perfectly. After you have installed the new, patched boot.img - just restart the tablet and then install Magisk Manager apk.
    Your device is now rooted :)

    Do you have the firmware for the M5P4 for the non-Chinese version, preferably European? I managed to bork my tablet and I'm having problems installing gapps on the Chinese version. Thanks.
