HavocOS finally on T1P3!

Thanks [MENTION=4818077]rbt07[/MENTION] , that tip made it! Immediately after the flashing of the TWRP recovery, I started pressing POWER+VOLUP and this time it worked!

I flashed other ROMs and TWRP before and honestly, I have never had this issue in any of those devices. I think the fact that the recovery gets replaced after flashing is quite anomalous and it would be good to mention!

However, the installation of HavocOS did not go as smoothly as in that video, so let me share a few additional steps I needed to perform which may be useful to other users:

- once I got into TWRP, my internal storage was not recognized and there was no way to mount it, so I could not select any file to be flashed

- I loaded those files on an sd card and inserted into the tablet

- I got back to TWRP, selected MOUNT and mounted the sd card

- I went to INSTALL (finally the files were there) and then followed the steps in the video

- during the initial configuration of HavocOS, I got stuck at the face recognition step, as for some reasons my camera was not working and the app was freezing

- I went back to TWRP and done a factory reset, then rebooted to HavocOS and skipped the initial configuration (I ran that process afterward and the face recognition step worked)

Additional notes:

- The original Teclast keyboard works just fine. If it does not work at the first connection, reboot and try again

- I was able to use my sim card to both perform calls and connect in 4G

- The lockscreen seems to be fixed to portrait mode. Once the screen is unlocked it will pick up the rotation config --> but I guess this is a normal behavior
[Android General] rbt07:
Congratulations, you did it.

I followed the instructions exactly and it was easy.

I am very satisfied with HAvocOS, everything works for me.

Yes, the lockscreen seems to be fixed to portrait mode.
[Android General] gattone_16:
hi to all I have installed HAvocOS all working except when I charge with the tablet turned off the fixed figure of the battery remains without turning off does it do it to you too?

how can i solve?
[Android General] rbt07:
Charge tablet when it is ON. [emoji16]
[Android General] ilbarba:
I followed the guide and installed Havoc, I had problems rebooting and poor wifi signal.

On the advice of a user of a Spanish telegram group I installed the blissrom. In my opinion it is much better.

I just want to say THANK YOU. I don't know if this is a placebo effect, but after flashing this, not only the screen refresh rate is right, but also the touch response is better. Maybe they are related, or it is just my idea. Now the tablet it's perfect except for the blinking led when charging, but that´s Ok because I have the case with cover so I don't see it. Unless there is a solution, I'm quite happy with the result. Again, thank you a lot.
[Android General] gattone_16:

Hi, does it work with all versions ? I have t1p4
[Android General] data123a:
I installed Version 1.0 on my t1p4 & it works fine
[Android General] gattone_16:
i installed the 1.1 but did not have the magisk installed

i 60hz 1.1 does not have them?
[Android General] rbt07:
Magisk is pre-installed, but you have to install Magisk manager to see options.

there is link in instructions (last point), or use this: Magisk Manager v8.0.3

Version 1.1 = version 1.0 + Magisk.
[Android General] rbt07:
It works well for versions: T1P2, T1P3, T1P4.

Me personally have T1P4.

Hello everyone,

What rom do you recommend for the Teclast T30, I have used the Havoc OS and it works quite well but when I browse the internet with Google Chrome or any browser, I suffer reboots on the tablet.

How's the Blissrom going? Does everything work fine or does it also suffer from sporadic reboots and is another rom better?

I currently installed the official v. 1.04 ROW

Hello, and it does not restart while you surf the internet? It happened to me and I chose to remove it and put your hybrid rom v.1.1 which is great, thank you very much

Hola, y no se te reinicia mientras navegas por internet? A mí me pasaba y opté por quitarla y poner tu rom híbrida v.1.1 que va genial, muchas gracias
[Android General] juansan10:
by the way, in your hybrid rom v1.1 I uninstall a Chinese application that brings and if I restart, it is back, how could it be erased completely so that it does not come out again? Greetings and congratulations for the rom, it goes like a shot !!!!

por cierto, en tu rom híbrida v1.1 desinstalo una aplicación China que trae y si reinicio, vuelve a estar, como se podría borrar del todo para que no vuelva a salir?

Un Saludo y enhorabuena por la rom, va como un tiro!!!!
[Android General] rbt07:
If I remember correctly, there are only two Chinese applications.

To remove it try use System app remover . But be carefully, this may cause the system to crash.
[Android General] juansan10:

[Android General] jak00jak:
thx rbt07 for your work. I have tried to install your hybrid rom 1.0 on my T1P2 (EEA version) T30. It all seems to go fine BUT the tablet (screen) does not switch on after the green icon is displayed in the tool, the screen remains black after pressing the power button. I say screen as I suspect that the tablet itself is on but the screen just stays black - see below.

I managed to go back to the stock rom 1.01 - was first really worried to have bricked my T30. However, when I try to flash the stock rom, I first had to do a long press (to switch it off) before the Tool starts to flash, that is why I suspect an issue with the screen.

Anybody else seen this problem with the T1P2? I could try the Havoc Rom but as this also involves burning the 1.04/1.05 ROW roms, I am worried that I will face the black screen again and at that stage it may not be possible to go back to 1.01- any advice is appreciated!
[Android General] rbt07:
You don't have to worry if you followed the instructions, you can't do anything wrong.

The instructions have been verified many times and are OK.

After successfully installing the ROM (according to the instructions), the first boot takes a long time. Disconnect the tablet from the PC. Then press the Power button for about 20 seconds and wait for the tablet to start. If it does not start, wait about 1 minute and press the Power button (for 20 seconds) again. Finally, the tablet starts up.
[Android General] rbt07:
Has anyone tried the Chinese Beta version of Android 10?

I don't know why the IMEI repair tool is included in the package. Is there a risk of losing IMEI?

Is it possible flash the hybrid firmware with 60hz trough Twrp only? Or just upgrade the hz using only the tablet? I already unlock the bootloader and have magisk installed
[Android General] jak00jak:
worked like a charm, thx again! not sure what went wrong first time around.
[Android General] rbt07:
Hi, I tried it again. After sucessfully flash ROM, disconnect tablet from PC and wait about 1-2 minute. Then push a hold Power button for about 15 seconds. Tablet should start. If no, wait 2 minute a then try start tablet again.

1st start after ROM flashing takes long time. Next starts are quick.
[Android General] jak00jak:
all worked perfect! great job.

was thinking about installing 1.2, I see there are two versions: 1.2 and 1.2a, which one shall I go for? took 1.2a - worked well.

Again THX for all your work and help. My T30 was a real pain before with an unusable touch screen, now it is a great tablet.
[Android General] nabongX86:
SD Card fix or not? or only Havoc OS fix the sc card ntfs/exfat?
[Android General] rbt07:
Vesion 1.2a is newest. Use it.

Yes, all version Hybrid ROM have repaired touch response and 60Hz display refresh rate.
[Android General] nabongX86:
what about SD card exfat?
[Android General] rbt07:
Unfortunately, official ROMs (1.01, 1.04, 1.05) for our tablet no supports the exFAT / NTFS filesystem on the inserted SD card in removable storage mode.However, if you set the SD card to the internal storage mode, it is also possible to store files larger than 2GB on it.

LOSQ GSI ROM supports NTFS filesystem on internal SD card in removable storage mode. But LOSQ do not recognize exFAT there. The problem is that our TWRP recognizes the FAT32 / exFAT filesystem on the SD card only.

So, If you setup NTFS filesystem on internal SD card, LOSQ ROM will see it, but TWRP will not see it.

If you setup exFAT filesystem on internal SD card, TWRP will see it, but LOSQ ROM will not see it.

Can I use the GSI image without actually disabling the encryption? I don´t want to root my tablet anyway. Or the disable force encryption is required.

I tried the Lineage GSI ROM, but the camera doesn´t work.
[Android General] rbt07:
If you want to use GSI ROM, you need to install TWRP and then the encryption will be removed.

For me camera works well in LOSQ-Lineage 17 ROM.

This file: losq-v224-201017-arm64-bgN.img.xz
[Android General] Medard22:
Yeah I figured that out eventually. The camera app froze everytime I turned it on in Lineage. I tried some GSI ROMS and eventually returned back to your Hybrid ROM. I guess I´ll just wait if Teclast ever releases an official Android 10.
[Android General] rbt07:
For me both cameras on LOSQ ROM works without any problems, I am using LOSQ everyday.

I have tried almost all GSI ROMs, for our tablet Teclast T30 are the best: HavosOS and LOSQ-Linegae 17.

But it must be said that all GSI ROMs have some minor problems in common (doesn't work: broadcasting on TV, calls via BT; offline charging does not work normally; problems with GPS etc etc) . Therefore, it is true that the original ROM has the least errors, and also my Hybrid ROM, which is made from two original ROMs (1.04 and 1.05).
[Android General] Yrian:
Hi i have downloaded the lineage rom from this link but it comes with an archive named: "bless-v300m-210225-arm64-bgZ.img.xz" i saw the havoc os video tutorial and it said the rom have to be in img format, so do i just need to delet the ".xz" and flash trough twrp and then format data?
[Android General] rbt07:
.xz is archive file, like RAR or ZIP.

You must unpack .xy archive to get .img file!!!

I used WinRAR to unpack .xy archive. WinZIP should work also.
[Android General] Yrian:
Yeah i discovered i have to unpack later, but my file is .xz not .xy

Sorry, I mean .xz.

[Android General] rbt07:
Flashing Hybrid ROM is the same as flashing original ROM. No worries. Hybrid ROM is made from two original ROM.
[Android General] RomerGG:
Hello rbt07, first of all, thank you very much for your work, the rom is going fantastic.

I've been using the ROM for two months, since I use the tablet every day, but I have a problem that makes me have to uninstall it and I would not like to.

Since I installed it, I have continuous problems of disconnection from the wifi network, I get the error that the password is incorrect, but it makes no sense, because when I turn off and turn on the wifi again it reconnects correctly.

I have completely formatted the tablet, and reinstalled the rom about 3 times, but the wifi problem is still present.

If I am on a work call, it is very problematic to have to reconnect several times because of wifi downtime.

Can you take a look at the problem?

Do you need a log?

Thank you very much.
[Android General] rbt07:
Hybrid ROM is used by many people and no one reports problems with wifi. I recommend you try another wifi router. Or change the settings of an existing one.

why not use a gsi instead?
[Android General] Werct:
UI there is faster for me, and it has more modern libraries and videodrivers, so it doesn't have some minor bugs that GSIs have (like chrome crash on video playback and MTP connection shutdown after some idle). Also Chrome-like 64-bit browsers had Vulkan rendering enabled by default, but is seems that's not the case anymore since version 92.

Also the new kernel (4.14) has lmkd instead of legacy low memory killer, and uses schedutil instead of schedplus scheduler (whatever it is, perhaps an mediatek proprietary technology).

[Android General] muil:
I could install everything but the gsi because there is no system partition on twrp. I tried to flash system.img to Super and made a mess. Then tried on fasboot but there is not system partition. Any advise?

Update: I managed to install A12 gsi via fastbootd as fastboot and twrp are useless for the job. The prob now is twrp not completing booting so I can not flash magisk :(. I don't recommend anybody upgrading to A12 yet, the instalation is tricky and flipping windows is laggy.

(The flashing problem is now solved by the new twrp fixed by Werct).
[Android General] :
None that I am aware of. (I have two build-environments set up, one for pmos, the other for Android 9 or 10 (10 has a number of issues, holding off for now but intended) but I need either stock firmwares or a stock recovery.img to begin tinkering...) T1P2 and T1P4 are different enough that the TWRP builds don't work correctly (partitions/kernel/drivers?). As for original firmware, depends on version you have. T1P4 has no publicly-available download of firmware. In fact, that's why I'm trying to get anyone to upload a copy of their recovery.img, so I can begin porting TWRP for T1P4 (I accidentally flashed instead of booted my recovery.img).

T1P2 and T1P1 are available from Teclast's website. Be careful how you flash, considering no TWRP available for T1P4 to backup everything.
[Android General] murigny64:
This tab is treble compatible.

T1P2 have treble A/B partition table. (for EU firmware).

You have to check your partition table with an app like "treble info"
