You should have tested it before posting it in the first place.

 

[TechGuru123]

can't test it...I have a m30 not a t30
I'm not really the testing type anyway....there are others more suitable for that

Phone calls can't work without IMEI

Is just me or this tablet have low frame rate scrolling?
I have checked the screen refresh rate and is fifty something, which is less than 60fps.
Is there a way to set refresh rate to 60fps?

I have noticed the same thing, the page scrolling is quite slow compared to other phones/tablets.
However there is another more annoying thing that is driving me crazy i.e. the pull down notification bar activates randomly without any touches or user interaction.
Please see the video below:

Do you experience this issue? It might be a hardware or a software problem?

I don't have ghost touchs, but I believe the touch quality is not good. I have enable the touch coordinates in development mode, and I realize that the touch step is 4 pixels. That's why the scroll feels strange.
Another anointing thing is the sensitivity. I bought a Tempered glass and I had to remove it because I couldn't write a message using a keyboard, without losing some touches.
I hope that a firmware update may fix this issues.

hello,

I have the same problem....low touch sensivity, the tablet it's arrived with tempered glass and I was thinking to remove, because it's hard to write and you lost some touches, is it possible to write to teclast? Because tablet it's good but this need an update of the software

 

[PandaKiller]

If you remove the tempered glass, you can write smoothly

At this moment I have root but my bootloader is locked, so no TWRP recovery.
Do you have any idea if it is possible to do that with only root privileges?

Just wonder can I use my quick charge 3 charger to charge this tablet ? In other words does more voltage than 5v will burn this tablet ?

By default the charger only outups the 5V. If it detects by software that the device is compatible with quick charging, than it changes the voltage profile.

I have a Teclast T30 T1P4, yes T1P4. Developer Options->OEM Unlock, fastboot flashing unlock, used SCREEN TO CONFIRM, unlocked now. Going to need a TWRP but I've not delved into compiling TWRP.

Teclast T30 T1P4:
(Up to date as of 1/21/2019, v1.01_20190906). I did make the mistake of flashing the wrong recovery img. So if anyone can tell me how to grab latest full firmware, would appreciate that. X_x; Currently flashed it with the recovery from a T1P2 firmware in hopes that if something does go wrong, maybe the T1P2 recovery img will maybe not crash and burn.

Trying to find a way to backup the current boot.img and then Magisk-patch it. Thought for ****s and giggles to try a T1P2 boot.img (boot-only) and it simply rebooted. (MTK Droid Tools just does not work for me, despite drivers, etc. SP Flash Tool needs a Scatter File I do not have.)

Teclast T30 T1P4:
(Up to date as of 1/21/2019, v1.01_20190906).

Managed to get root and Magisk on my T1P4.

Enabled Developer Options
Enabled OEM Unlock
Rebooted into Fastboot
Issued 'fastboot flashing unlock'
Followed instructions on Tablet Screen to Confirm Unlock
Used firmware from T1P2's Scatter File with SP Flash Tool to dump ROM except for recovery, mine is herpderped.
Copied boot.img (backup from SP Flash Tool) to internal storage of Tablet.
Made Magisk patch boot.img, kept encryption and verity.
Backed up magisk_patched.img.
Rebooted into Fastboot.
Issued 'fastboot erase boot' followed by 'fastboot flash boot ./magisk_patched.img'.

Success. (Noting that ctsProfile:true and basicIntegrity: true)

I verified boot.img was correctly identified before doing all of this, manual observation and a lot of Linux years (but newish to Android). I wouldn't trust the Scatter File from T1P2 until independently verified by someone other than myself. Couldn't get MTKDT to work at all on Linux.
Will manually patch my boot to get rid of Orange State.

I've also manually patched lk and flashed to my lk and lk2 to rid it of Orange State. If I could figure out how to extract the kernel from lk I'd just bypass the 5s delay altogether.

Forcibly removed Adups FOTA spyware including Adups FOTA Overlay. Backed up before. Part of it gets restored by vendor.img, but not enough to be harmful.

Does ANYONE have recovery.img from T1P4? Trying to port TWRP..

 

[tiltkoko]

When I got my T1P4 it rebooted a few seconds after turning off the screen. Eventually got $25 rebate for it.
Then I flashed a magisk patched T1P2 boot.img and installed busybox, and now it works 100% without rebooting.

Do you have a backup of your recovery.img? If so, I can start work on porting TWRP. Desperately need it. (Riru, soft-brick.) Also, you could have used Magisk to patch your current boot.img and copied to sdcard, then flashed that instead.

---

For those who have patched a few things, remember to also patch lk.img (lk, lk2) to report Green state instead of Orange by patching androidboot.verifiedbootstate=orange to androidboot.verifiedbootstate=green (replace 'e' with nullbyte.) That way if Magisk takes a crap on you and you need to run stock boot.img, you'll hopefully continue to get ctsProfile: true, basicIntegrity: true.

Anyone else spot this? Tap 5 times:

Settings:System->Advanced:About tablet:Device info:Cpu type

 

[Deleted member 4370975]

Managed to build a MagiskInit64 CORE-ONLY and patched boot.img. (That way if your Magisk is boot-looping you because of a bad mod, you can boot with root and all modules disabled.) If interested, ask and I'll find a filehost. T1P4-only.

Any custom firmware available for this tablet? Or someone has a set of clear steps with download links to reinstall the original firmware from teclast?
My unit has ghost touches on the display and maybe an installation from scratch will fix it, worth to try it at least...
