Success!
Successfully booting into TWRP using this method. Thanks. My firmware is S040 (year 2017).
Dude, can you reupload the TWRP3 file from google drive? It got deleted. THANKS!
Here is the last version at the moment of the Maze alpha ROM (tested only in 4GB version)
It's a complete ROM, not an OTA update, it can be flashed using the provided TWRP 3.2.1 version, I ported from a Jemmini (many thanks) version for Bluboo S1.
Unfortunately, the TWRP cannot be flashed (issue with the touch panel), only launched by fastboot.
The ROM is the same as the v8 official one except that it is rooted using Magisk 15.2 and busybox 1.27.2 (thanks to osm0sis) is installed in /system/xbin
There is also a SPFlashTool clean version of this ROM, useful in case of troubles (as official: no root, no busybox)
1- Reboot you phone in fastboot mode : adb reboot bootloader
2- Flash the provided TWRP : fastboot flash recovery recovery_maze_alpha_4G_twrp-321.img
3- Reboot to TWRP recovery
4- copy in your SDCARD and install, in the running TWRP, the downloaded ROM V09 : Maze_Alpha_4GB_v09_TWRP.zip
The first boot take some minutes so be patient.
Here the SPFlashTool versions :
MAZE_Alpha_4GB_V09_SPFT.zip
Here, if needed, my V09 TWRP backup (new one from 21/04/2018) :
TWRP_BACKUP_MAZE_Alpha_A_V09.zip
Credits to Jemmini and Magisk team.

Thanks for this Rom.

No it is already rooted.
Reboot your phone to android, and then install MagsikManager.apk
I am editing my post to give you a 100% working TWRP 3.2.1 for our beloved Maze Alpha 4G :victory:

After I installed this rom, and freezed the hot knot, baidu_location FM Radio, etc, the BT connection did not break.

Hi dreambo,
do You know if there's a stock rom for download from maze alpha x? I think it's important for normal users and developers to get one. For normal users it's important to have an option to reinstall stock version and for developers I think it's the source for custom roms (e.g. Lineage Os).
If You know a source, can You please give us a link?

No I not have any source, I am just a simple user like any other.
If I have any source or if I can make a ROM for MAZE Alpha X, I will do it and I will share it with every body, as I do until now for the MAZE Alpha 4/64
Hi
Sorry for stupid question, but is flashing with SP Flashtool an option to get root without wiping all data (unlike all other methods involving bootloader unlocking)?

Unfortunatly no. As you will see repeated times in the forum, people have issue with phone not booting after changing from stock recovery to twrp. This is do (most likely from) to verified boot setting. And by unlocking bootloader we can bypass verified boot. So without unlock you might get a successfull load into twrp, but android will not boot.
Hello to all and please help if you can.
After unlocking the bootloader and flash the rom I'v got orange state with bootloop. Then after trying to fix it (wrong way) and relock bootloader and got red state with bootloop. I read that flahing back to stock fix the problem but I have no success with the rom provided in this post, the v5 from maze, the latest flash tool and the maze alpha flash tool... in all cases I get DA error(maze flash tool) or DA MISHMATCH (sp flash tool). I also tried different pc and cable with no result and finaly can't get fastboot. If that helps I've got the same flash tool error before the procedure. Every help will be appreciated.

First unlock again your bootloader and use fastboot to flash boot, recovery and system partitions:
fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot flash system system.img.
Those partition images can be found in the ROM for SPFlashTool I have provide.
After that you can boot android normally.
If you any TWRP backup, you can restore it after flashing the TWRP.
Thanks a lot for your reply....
the problem is that i cant boot into fastboot to unlock bootloader....
the phone bootloops all the time, shows the red state alert and even with vol+ pressed the menu to choose recovery or fastboot doesn't apear... thanks again.

Is there any way to unlock the bootloader in my situation or/and enter the fastboot mode in order to follow your steps... thanks.
i downloaded the custom recovery for t20 (TWRP-3.2.3-TwrpBuilder-t20-2019-01-18_20-02) from gethub "i cant attach the link because of the forums rules"
then flashed it using fastboot , but then the tablet didn't boot into normal mode but i was getting the boot mode selection when i hold the (power + volume up) which gave me access to recovery mode and fastboot mode
the problem is that this custom recovery had issues with the touch screen and was basically not usable .
so i switched the phone into fastboot and i flashed the patched boot image that was working before but the tablet still didn't boot into normal mode , then i flashed the stock recovery image and now every thing gone .
the tablet has no options to boot into fastboot or recovery anymore.
basically the tablets boots and i get the teclast logo then the image of the broken android with a "no command" on screen and nothing else
i tried holding the volume up and plug in the usb-c cable but i got the same broken droid
holding volume up and power doesn't give the options for boot modes anymore
i would appreciate any help a this moment , thanks

SP Flash tool should help you. Install stock firmware and everything should be restored, a device on MTK isn't so easy to kill. Just check the revision of your device (E1 or E2, on the back cover). I tried this TWRP and already spoke of that control it only with mouse (https://forum.xda-developers.com/showpost.php?p=78710093&postcount=5). I have my own version of the TWRP (3.2.2), there's also a problem with orientation of the screen. But PhilZ recovery works without problems, the management of keys.

thank you very much for providing the y.disk link , i spent the whole yesterday searching for a way to download from baidu without luck.
i managed to flash the stock software (using format all +download) and it worked and now the tablet is up and running (unfortunately its chines ) i changed the language but there is bits here and there with chines still i cant complain.
there is no recovery image with this tablet , do u think i should flash the twrp recovery even if it has touch issues.

Those are the notes i made for my self regarding your issue:
at the end we may get an error when flashing the patched-boot.img using sp flash tool
so we need to use fastboot instead
first we need to install ADB and fastboot in the PC (follow link bellow):
https://www.howtogeek.com/239798/how-to-unlock-your-android-phones-bootloader-the-official-way/
then power off the device then (hold the volume up+ power ) to enter the BOOT mode (the usb must be disconnected)
then select the fastboot from the menu
then we can use the commands :
#fastboot flash boot c:/patched_boot.img --> make sure the image is in the C folder
if this failed we need to unlock the OEM
#fastboot oem unlock -- > then confirm from the tablet
then try again
#fastboot flash boot C:/patched_boot.img
and when its done we can issue the command for restarting tablet
#fastboot reboot

Standard phenomenon for Nougat/Oreo: to mount a partition /date, must first format it. With loss of user data!
Some TWRP editions don't require this, /data mounted.
Hello.
Thanks ViAlexSt for the help, but I´m still having problems with root
, I try with (MTK) Auto TWRP recovery porter and with MTK Auto Philz recovery porter, with success only with TWRP.
Wiith Philz only get into recovery, when go to the OS the screen freeze with Teclast Logo in red.
With TRWP have an error, not able to mound device.
Is no possible install zip or create a backup.
Any idea??
I have a T20 T2E1
Thanks
I format with SPFlashtool with format+flash option, but not work, no backup, no any wipe.
Still with message Unable to mount parition.
I will try with an older version OF TWRP.
Some screenshots.

Did you manage to do it? It's necessary to format the partition from CWM/TWRP!
Do you need additional explanations?

Thank you very much for yor reply.
Yes I try formating with twrp but the same problem, at the end I take the risk and use a downloanble image "TWRP-3.2.3-TwrpBuilder-t20-2019-01-18_20-02". The one generated with the porter doesn´t work for my Teclast T20 (T2E1).
With this one "TWRP-3.2.3-TwrpBuilder-t20-2019-01-18_20-02.img works at the first".
And after that I was able to install "Magisk-v18.0.zip" and "no-verity-opt-encrypt-6.0.zip".
And finally I get root access, but after a wile I see the propblem with the IMEI wich was Inavild, after try with many options like generate the file MP0B_001, use Uncletools, droid tools, and many other Apps.
Finally today... I found a solution in a Spanisf Forum Dual Sim, Thanks to user "pedrogem" the most easy way to set an IMEI.

Hi toxstoxs.
Is already done in this link with all the downloads https://romprovider.com/2019/01/teclast-t20-root-twrp/.
I follow these steps exept the use of adb. In stead, I used SP Flash Tool, the utility included in the the original ROM which you can download from the official Teclast website.
Be sure to make the backups mentioned in the procedure NVRAM and nandroid, in case you lose your IMEI you will need restore the NVRAM backup.
With SP flash tools, upload the recovry.img "the downloaded TWRP from the link above" and your boot.img "patched on your device with magisk manager from you original"
I use the boot image from the original rom downloaded from Teclast, which I flash previously.
Be sure to make the backups mentioned in the procedure NVRAM and nandroid, in case you lose your IMEI you will need restore the NVRAM backup.
Just take in mind... touch screeen is not working well in TWRP you should use a mouse, the touch screen is in portrait possition but wou will see the screen in landscape, I do it without a mouse but is not easy, if you can get a mouse will be bether.
Regards.

I went troght that step by step guide but :
1) into Pre requirement steps, i made a NVRAM backup with SP Tool.
step 2 is not so interesting to me as the tablet is new so no personal data are saved.
point 3 : How suppose to make a nandroid backup if no TWRP is intalled???
then.. i suppose that it mean to INSTALL a TWRP and just after make a nandroid backup right?
but...
just after ulock the bootloader and reaching step by step the point 7 and 8 of the guide,
after the command "fastboot boot recovery.img" the device reboot and go in permanent loop.
No way to access the recovery.
is there something that i may check? just once i been able to enter the twrp and the main problem were the impossibilty to access and format the /data partition so, no factory reset were possible and obviously no bbot as well (permanent boot loop).
Im not use adb tools, im only use sp fash tool.
I do it like this.
1 flash the downloaded Rom from Teclast with SP flash tool, to get all fresh.
2 Enable usb debug and oem unlock
3 copy in your device the stock boot.img from the folder firmware from the zip downloaded from Teclast,
4 in your device install the app Majisk manager and use it to patch your original boot.img
5 copy into sd the files magisk.zip, No verity opt encrypt.zip,
6 with sp flash tool flash the patched boot.img and the downloaded TWRP-3.2.3-TwrpBuilder-2019-01-18_20-02"]twrp renamed to recovery.img ”this was the only one trwp which works on my T20”https://github.com/TwrpBuilderTests/android_device_teclast_t20/releases/tag/TWRP-3.2.3-TwrpBuilder-2019-01-18_20-02
7 reboot in recovery with TWRP and install magisk.zip and no verity opt encrypt.zip
This might help you after realizing that you want to install custom ROM again after upgrading to android 11 MIUI but you cannot install android 10 or 11 based ROM and stuck with either boot loop or android rescue party.
WARNING: This might wipe every writable partition. Charge your phone at least 20% or more to prevent from destroying these partitions.
Instructions:
1. Download firmware from here
2. Download full ROM (either recovery or fastboot) from here
3. Save the firmware zip file it in either internal storage or sdcard. Reboot to TWRP afterwards
4. Tap install and find the zip file in your storage and install. Wait for a couple of seconds to get done.
To install full ROM
Recovery
1. After installing firmware from recovery mode, don't reboot. If you reboot the system it will fail to boot. Boot to fastboot if you fail this step and flash a recovery image. Proceed with next step.
2. Install full ROM flashable zip from sdcard or internal storage.
3. Format /data. Reboot.
Using fastboot
1. Boot from fastboot mode
2. Extract full ROM fastboot zip file.
3. Open miflash and locate the fastboot folder.
4. Choose flash_all. Click start.
5. The phone reboots itself. Boot to recovery mode and wipe data.
All done. The phone is now downgraded from android 11 back to android 10.
Note: I got 2 anti triggered when attempting to downgrade the phone using recovery and fastboot without installing firmware zip file first. RIP me I guess I voided my warranty anyways so doesnt matter as I already applied some insurance for my device.
TL;DR: Installed Recovery will get erased as I mentioned in WARNING. Please don't skip every step.
Edit: since it made confusion, I split steps for recovery and fastboot mode.
Has anyone tried this procedure?
Im on 12.0.6.0(EU). Bootloader locked (wait 3days) so no TWRP. Want downgrade to 12.0.8.0(EU) and flash Pixelexperience ROM.
It will work?
I'm a bit confusing... Links inserted in first 2 points seem to be the same link. So what I've to download exactly?
I'm on 12.0.7.0 Android 10 but I'm curious to try 12.0.6.0 Android 11 stable beta released some days ago...

Its not the same. First one is cca. 80MB of size while full rom is 2.4GB for recovery and 4.4GB for fastboot.
I did this method yesterday and its working. No problems whatsoever.
The only thing i would add is you need both versions of rom - recovery and fastboot. Recovery when you flash for the first time in recovery and fastboot when you flash with Mi flash.
And my advice is, android 11 miui is really bad. Its not finished, it stutters a lot, u can't use third party launchers with gesture navigation (at least in my case, Nova lanucher), performance is bad.
Not worth any time.

Ok, ok, good to know. I'm just curious... I'll remain with A10 till when A11 will be good enough to be used as a daily driver

did you try to flash firmware file from twrp recovery first? also that error means that a checkpoint failed which you need to disable or remove in configuration settings.

did you tried recovery or fastboot flashing? and did you installed firmware first before installing full rom?

i only tried recovery method and it works fine after days of trying. 12.0.6 android 11 is still buggy and miui needs to fix it a lot. most of apps are not well optimized for this flavor.
Today unlocked bootloader. Flashing 12.0.8.0 (i have 12.0.6.0 A11).
Everything work perfect. No bootloop, bootloader relock and works fine
People are probaly skipping some steps.
1. Download Firmware small size files
2. Download full Firmware, both - fastboot and recovery (put it on SD card, small and recovery)
3. Install Twrp or Orangefox recovery (download it from somewhere)
4. Enter into recovery and install small firmware FIRST, dont reboot, install big firmware (recovery version) SECOND
5. do not reboot
6. format data
7. Now reboot into fastboot
8. Extract fastboot firmware zip into new folder on desktop
9. Start Mi flash, select that folder where u extracted files and tick "clean only" on the bottom of the Mi flash if u want to leave bootloader unlocked and from drop down menu near that pick "flash_all.bat".
Thats how i did it.

i did the same, but looking to partitions of system, product and vendor, i understand that flashing the files via recovery and fastboot they dont write in that partitions.
looks like the partitions are read only. thanks
I try to flash a custom rom like arrows os via recovery , the rom shows the boot logo of arrows rom, and then bootloop.

Did you flash it from the built-in recovery or with MiFlash? (My 167 hour waiting period ends tomorrow)
Solved people. change the version of the Mi Flash.
Hello all,
It's a long time that's i haven't post a thread here but i have a question.I have a Poco with MIUI Global 9.6 Stable (9.6.25.0) for ROM with a Android Version 8.1.0 OPM 171019.011 with root acces, unlocking bootloader and TWRP 3.3.0-0 installed.
I would upgrade my phone to something "newer" (A ROM with Android 12 if possible) and conserv the root access and my apps.
I have read that now ,we should have 3 files to do that (firmware,system and vendor) to make a wipe and install new ROM with TWRP.
So my question:
-Is it possible to upgrade Android 8.1.0 to Android 12 witn a new ROM? (i have read something about kernel in Android12 but haven't understand all)
-Have i missed some steps or just download files,boot TWRP,wipe and install newer ROM+firmware and vendor appropriate is good?
-Which ROM do you recommend?
Thanks for the previous answers.

It's not possible to switch from stock ROM to custom without doing clean install. You will have to root again.
First update to latest Official Stock ROM, then take backup of your files to your PC or to SDCard (if you have one) , flash to latest Official TWRP and check my POCO F1 Ultimate Collection & Guides. You can find everything there. I have awarded recommended ROMs in my collection.
Feel free to ask if you have any question regarding the guides.
Thanks for the answer.I have begin to read your guides.
If i understand good,it's not possible to conserv my root,unlock bootloader and twrp when i upgrade to android 12? Automaticaly i should root again my phone and restore with titanium backup my files,contact,....?

First you need to take backup of your files to PC or External SDCard.
Then you should update to latest version of MIUI via OTA if it's possible or via TWRP (you can use the stock recovery rom to do it via twrp). (You can also use my guides for clean install stock rom)
Then you should unlock your bootloader if it's not already unlocked.
Then flash latest Official TWRP.
Then flash latest firmware (not vendor) just to make sure you are on the latest. (You should be on latest firmware after updating to the latest MIUI version)
Then Wipe everything + format data according to my guides and flash the ROM you want. If you choose A12 Pixel Experience or crDroid keep in mind that these ROMs use their own recovery because these are encrypted by default ROMs and TWRP can't handle the decryption of A12 encrypted ROMs yet. So to make OTA updates and that stuff work correctly devs of these ROMs decide to use their own recovery which can handle the decryption of encrypted roms and as result to make OTA update work fine. Check the installation instructions of these roms in their threads. (Afterwards you can use adb sideload to flash stuff using these recoveries)
After that, flash Magisk since you want root.
Then you can restore titanium backup if you want.
OK i follow your instruction.Thanks
Hello retrial,
I have now updating my phone to MIUI Global 12.0.3 Stable with Android Version 10QKQ1.My phone is not yet rooted and now he is encrypted.The recovery is now Mi-Recovery 3.0
I have unlock again my bootloader.
Now to follow your instruction,i should flash the latest TWRP.
I have take TWRP-3.6.0_9-0-berylium in your guide.
I think i should do Fastboot Method because i'm now in Mi-Recovery?i'm right?
No problem with the encryption?
Thanks.
i have find this video.This is not the good phone but i think that the installation is the same:

Yes use Fastboot Method to flash TWRP. No problem with encryption.
After that follow my clean install custom rom guide to flash the ROM you want. Also please check the instructions in the threads of ROMs you want to flash. A12 crDroid and PE use their own recoveries.
Basically tell me which ROM you want to flash to help you exactly with steps.
Hello retrial,
i have a problem to install TWRP-3.6.0-9-0 on my pocophone.Everything working fine but in step 8 of your guide,i can't find my twrp.img that i have copied in 2 different case to test :
8. Boot into Recovery by typing in cmd: fastboot boot <recovery_filename>.img (The file may not be named identically to what stands in this command, so adjust accordingly and write the full path of it, check the example below).
This command will not flash permantly the recovery, it will just temporary boot into it and afterwards you will flash permantly the twrp.img you copied into your Internal Storage or SDcard in recovery partition.
For example: fastboot boot C:\Users\Retrial\Desktop\twrp-3.5.2_9-0-beryllium.img
Have you an idea to why i cannot find my twrp.img in the boot mode?

Send a screenshot what you type in cmd and where you have the twrp.img
Or you mean you can't find it in your device while you are booted on TWRP?

I have all the steps on my guide. Please read it carefully. It boots back to mi recovery because you haven't flash TWRP yet just booted into. After boot into TWRP u need to flash twrp in recovery section so it will stay after reboot.
Please read the steps.
Download portable Minimal ADB and Fastboot and latest Official TWRP recovery.
Open cmd from minimal adb and fastboot and write:
fastboot boot and the path you have TWRP.
Example:
Code:
fastboot boot C:\Users\Retrial\Desktop\twrp-3.6.0_9-0-beryllium.img
Then proceed with the rest steps in my guide. Connect ur device to pc while u are booted into TWRP and copy TWRP.img to your device. Then in TWRP press Install Image and select the twrp.img u just copied into ur device. Select recovery and done.
I have made a video to show you what happened (sorry for the bad quality and the moove) :
I think a video is easyest to understand my problem.For information my bootloader is unlock and usb debugging ok.

Hmm strange, probably of MIUI. Anyway since you are going to flash custom rom, when u flash twrp in recovery go back and select wipe and wipe everything (read my clean install guide), go back press format data type yes, and then reboot to TWRP.
EDIT: I just saw u rebooted to system. That's not what we want. Press reboot to recovery.
i reboot first to bootloader after have flash the twrp.img in recovery.That's only the second time that i reboot to system to use the normal mode of the phone and reboot after to recovery mode to show you that mi recovery is back.

The TWRP flashed correctly. You overlap it again by pressing reboot to recovery from MIUI updater.
Don't do that...do the combination to boot to TWRP after flashing it. Power+Volume Up.
And continue with clean install steps in my guide to flash custom rom.
In my guide I write nowhere to boot to MIUI and press from MIUI Updater reboot to recovery, please stick to my guide and you will be fine.
