Recovery

I have the T1P4 recovery.

Had ca. 100 posts here years ago, but now somehow just 1, so can't post attachments or links.

/RANT/
[Android General] tiltkoko83:
Recovery

Ok. Here is T1P4 recovery partition copied with dd.
[Android General] murigny64:
install twrp builder and upload your recovery with it.

your recovery will be use to build twrp
[Android General] tiltkoko83:
Twrp requests are stopped. So that is of no use..
[Android General] tiltkoko83:
This thread died down fast..

Since this device is treble capable, it should be possible to try gsi image. Have someone tried that?
[Android General] PandaKiller:
Unfortunately I don't have the knowledge, but I hope someone can do it. You will have my support ;)

Hello

I am using Teclast T30 with Zwift , sometime there are a lot of video lags , does exist any solution to run video better and faster ?
[Android General] murigny64:
No, sorry, the tab is not mine (my daughter) and i missed to flash TWRP for backup now

It should be easy to try a treble A/B rom. Just have to flash system partition.

We have all tools for that and recover:

- Original Rom with scatter, APDB, MDDB

- Flasher tool

- MAUI Meta tool ( for IMEI repair )
[Android General] :
Thank you very much for the recovery.img. So far, I have decryption of sd card working but no interfacing (touch screen). I don't get notified of things from XDA for some reason, despite my settings asking to be.
[Android General] Raulka:
Dear tiltkoko,

Mine T1P4 is rebooting too...

https://youtu.be/0GnXz4VLOlk

Your T1P4 is works good after the flashing below?
[Android General] Raulka:
I flashed the magisk patched T1P2 boot.img with T1P2's scatter.txt too, after restart, the T1P4 is Rooted! :good:

Then I Installed busybox, but the T1P4 is restarting when I turning off the screen.. :crying:

Nothing changed.. Courious, because If the T1P4 is connected to the PC, then not restarting with black screen, but without USB connection or on the charger this is restarting..
[Android General] tiltkoko83:
try out https://github.com/d4rken/wakelock-revamp/releases with at least cpu on.

I still have reboots on most boots, but once in a while it will work great, and then I try to never reboot it again. Have had it on 3 weeks on the same boot now.
[Android General] Raulka:
Yesss, You are the best!

WakeLock works perfectly, no more restart! ;)
[Android General] murigny64:
Hello

T1P4 firmware is available on Teclast china : http://www.teclast.com/tools/pad/putcode.html

enter T1P4 and you will have baidu link for it (extract code: 2tbe)

Carefull on this firmware:

modem and efs partitions may be different to your tab (europe/us versions)

but you can take recovery and boot verified img from this firmware.

:)
[Android General] ioura:
are any custom roms for the device?

Download from Baidu You need to download and install the BaiduNetDisk application and use one of this acc/pass from this youtube video.
[Android General] ilbarba77:
Okay, now I have the T1P4 firmware (thanks to Li Lei).

Exactly what steps should I follow to install Twrp and root recovery with magisk?

I was checking how to root my T30. I have a T1P4 but the version on the baidu available to download is V1.05_20191219 and on my device (EU), the latest available to download is V1.04_20191108, the one I have installed.

Can I use the Magick method anyways?

[MENTION=4291715]ilbarba77[/MENTION] can you share the file or user/pass to get the firmware?

Thank you.

GSI working

Finally flashed gsi image to the T30. It's working well.

Only thing you need to do is to flash Android 10 A/B image to system and factory reset.

Was on 1.01 firmware for the T1P4 before flashing gsi, never seen a 1.04. Sure you are not thinking of the one for T1P2 [MENTION=10730885]Nadazer0[/MENTION]?

Would like to know what kernel version the Chinese firmware and 1.04 is on. I am on 4.4.146 now.

[Android General] murigny64:
Amazing, it's the only interesting info since a long time :)

This forum is "XDAdevelopers" but 90% of posts are noobs or people who read diagonally :(

I'm very glad to learn about your investigation, you are not afraid to get your hands dirty and it's the XDA philosophy :)

You are now on AOSP 10 !!

What about vendor compatibility ? Any improvement ? Framerate scrolling ?

The T30 belongs to my daughter and i must be sure about some improvement before erasing her apps and data (no unlock, so no twrp backup) :D
[Android General] tiltkoko83:
I have had no reboots after upgrading and installing wakelock app. Before I think the rom killed processes with the screen off so it would always reboot. (hardware problem from day1. I/O error in kmsg)

With GSI images you still use the vendor files from what was installed before so no direct improvements there.

So would be interesting to know what's in the Chinese firmware etc.

AOSP with latest security patches is a good start for me.

Tried to patch lk,lk2 with "androidboot.verifiedbootstate=orange" to green, but got bootloop. Settled for removing the warning text..

Got tips for further hacking?
[Android General] murigny64:
How did you flash ?

Before flashing gsi system,

- you have to remove magisk or flash clean boot-verified and erase magisk folder too.

- flash orange state disabler

- flash DisableForceEncryption_treble

- wipe all

- and then, you can flash gsi.

- 1st boot without magisk patch installed

If allways bootloop, try to rename or erase /system/bin/uncrypt

..
[Android General] tiltkoko83:
There is no TWRP for T1P4.

I flashed latest boot.img with magisk, GSI and a wipe of userdata with SP flash tool.

Booted fine with that..

When I had bootloop with lk.img changed to androidboot.verifiedbootstate=green, just flashing it back with orange and it booted fine again. Since no TWRP cant't flash fancy scripts...
[Android General] murigny64:
Ok ! i don't renember that you have t1p4 variant ;)

It's even more courageous to have installed a gsi system without TWRP
[Android General] tiltkoko83:
So no one has testet the latest china rom files for T1P4?

Can you then post it to mega or something. I don't need the system.img, but want the rest..
[Android General] ilbarba77:
This is firmware T1P4 from Baidu

Nice ilbarba77 ;)

Found a small app to port TWRP to MTK:

https://forum.hovatek.com/thread-21839.html

register to download and disable onthefly antivirus.

On my drive: https://drive.google.com/file/d/1Tf7QRfUk4n8CnYFaMOyEgulTk7DmGh93/view?usp=sharing

- take recovery-verified from t1p4 firmware and put it on "stock-recovery" folder, rename it to recovery.img

- launch "mediatek auto twrp ...."

- choose recovery check and clic on "check"

- choose android version (?)

you twrp recovery will be create on output folder

make a backup of your stock recovery and try to flash with spflashtool

EDIT: i have tested on T1P2 (with t1p2 recovery) and it's working fine :) but no touchscreen (have to use otg usb mouse)

;)
[Android General] eprompc:
Hello!

And what about the T30 T1P3???? I just received it from Amazon.

Thanks.
[Android General] Martezgarki:
Coincidentally, I too received my T1P3 yesterday and managed to install Magisk on it.

If you look at the Chinese link they shared above, there is T1P3 ROM file but unfortunately, patching the boot files from those ROMs did not work.

I ended up using the T1P2 ROM's boot-verified.img and it works okay so far.

Side question: Anyone managed to find a GCam version that works for this tablet?

I am still waiting for new firmware to fix various existing bugs.

Hi

there is no Teclast T30 forum so may I ask a Teclast T30 question here ?

I bought a Type-c > HDMI adaptor . I started Spotify in Teclast T30 , then I connected Teclast T30 to my SintoAmplifier Yamaha Rx-V500D (HDMI port 3) using the Type-c > HDMI adaptor.

However no sound is sent from Teclast to my Yamaha Rx-V500D . What's wrong ?

Don't know how this keyboard work: perhaps if it use "USB" protocol 4 contacts 5V, 0V, D-, D+

T1P3 vs T1P2

Hi, i have the version t1p3, does the update work for this too, the problem of touchcreen slow to much this tablet.... What are the difference between t1p2 and t1p3?

Thank you in advance
[Android General] arnarn911:
When my unit arrives, I plan to try the following fixes:

1. Adjust Pointer speed

2. Disable Gestures if any

3. Install Touchscreen Repair/calibration app

4. Tweak Developer options

5. Update Firmware
[Android General] murigny64:
Send me your T1P3 and i will answer you :rolleyes:
[Android General] Adamooo:
Sorry i dont have that much money to give away unfortunately ? but if its of help i tried a screen calibrator app and it seems to improved it a little bit, the app sayed 7ms.

There is un update in the teclast chinese site but i can't download it since for a baidu account i have to insert my phone number and i prefer to not put it. Maybe it improve touchscreen i dont know
[Android General] arnarn911:
I received my T30 T1P3 version. Confirmed there is touchscreen lag issue. Tried the suggestions above except firmware update but issue persists. Hope to flash a A10 gsi firmware and hope to fix the touch issues.
[Android General] Adamooo:
In the chinese version there is an update for the T1P3, but i can't download it as you need an baidu account , maybe it fix the touchscreen problem, hopefully it will be released soon for american/european T1P3 too
[Android General] arnarn911:
Is it safe to flash chinese firmware to ROW unit?
[Android General] Adamooo:
Actually, i dont have idea, but if you can donwload it and upload to gdrive or some other cloud service, i will try. But if someone know it please let us know it too.
[Android General] Adamooo:
I flashed the firmware for the T1P2 model from the previous post that resolve touchscreen problem in my T1P3 unit, and for now does work all component, and the touchscreen is A LOT better!
[Android General] arnarn911:
Wow! Is it okay of you make a couple tests? Please install Touch Multitest and Screeninfo apps ans share the values you are getting.

1. Touch Multitest - average touch samples per second is 40

2. ScreenInfo - refresh rate is around 53.65 fps
[Android General] Adamooo:
I dont know if is another parameter not misurated by these apps as in touch multitest give me 43/44

and freshrate is the same. But that he freshrate was invaried already i knowed as little lag in the pich zoom there is yet, but with the old firmware it was almost impossibile to write with the keyboard now it catch all the key, is more smooth but other han the freshrate it seems as is an hardware problem of background as its to hard and not soft as other device i had, but the improvement there are for sure
[Android General] arnarn911:
Thank you. Lastly, can you share the firmware file name? If you can provide the link I appreciate it. I just want to make sure I use the correct file.
[Android General] Adamooo:
Sure, no problem....https://drive.google.com/file/d/1ZResfmNiAEhCjfspTmxeaWuyrqUI7XFm/view

I used this, beware that if you use the download only in the firmware upgrader software it will erase all data

Thanks so so much. Done flashing the firmware and magisk. I don't know if it's placebo but I think it does feel better now. :good::o
[Android General] arnarn911:
Those with T1P4 units, is it true that they dont have touch sensitivity issues?
[Android General] Wualk:
Just arrived

Hi all,

My Teclast T30 just arrived yesterday, and played around with it a bit. I am positively surprised by the tablet. So far everything works fine, and I have no issues with the touch sensitivity or lag. Sure, I am not an expert, but the screen reacts to my touch and does what I want it to do. And I haven't even removed the protective film yet (yes, even the film with the specifications is still there, I will remove it when I am sure I will keep it).

I have version t1p3 for the European region (EEA), and runs software build 01.20190906.
[Android General] NikosD:
I ordered my T30 on May 17 but due to stock issues (out of stock) they found one on May 30 and sent it to me.

It's T1P3...How come there is even newer than that ?

I have exactly the same tablet arrived today.

T1P3 EEA and firmware 1.01_20190906

[MENTION=9350973]All[/MENTION]

I couldn't find an official firmware in Teclast's site for T1P3 - only for T1P2 - and even that link had expired.

Do you know if scatter file of T1P2 works for T1P3 ?

Could someone upload it somewhere ?

Thanks!
[Android General] NikosD:
It's called MTK Engineering Mode and almost all MediaTek devices support it.

You can have access to this by third party apps or by simply typing *#*#3646633#*#* to the dialer.

Of course, it seems you discovered another way to access it.
[Android General] NikosD:
T1P3 for beginners

A summary for T1P3 after reading this thread.

The firmware arrived for my European version (EEA) is v1.01_20190906 and I can't find it anywhere to download.

Teclast hasn't uploaded any FW for T30 T1P3 EEA (European version) yet.

According to various screen test apps like ScreenInfo the

refresh rate

is ~53.64 fps and not 60fps and according to Touch MultiTest app the

average touch samples per second

is ~ 40 instead of > 150 for other phones/ tablets.

I can see a lot of people complaining about problems with scrolling speed and touch sensitivity/ accuracy BUT I couldn't reproduce that behavior.

I don't know if it's perfect or can be better, but I certainly can't see a reason to complain as is.

I have my screen protector removed immediately

after receiving T30, so that could probably make a difference.

Some users report better experience after installing on T1P3, a newer firmware for T1P2 which you can find here:

https://drive.google.com/file/d/1ZResfmNiAEhCjfspTmxeaWuyrqUI7XFm/view

Latest firmware for

Chinese

T1P3 can be found here:

http://www.teclast.com/tools/pad/putcode.html (thanks to [MENTION=4599772]murigny64[/MENTION])

The

ID

asked is T1P3, the

extraction code

asked is 7dhl and the latest FW is v1.01_20200104 but you need to download BaiduNetDisk app to download the FW and have Baidu account/ credentials.

If you have European or US version and you want to flash newest Chinese FW you have to be careful, as modem and efs partitions may be different.

According to [MENTION=2881640]Martezgarki[/MENTION], it doesn't work as is to patch the boot files from that FW and you need to take boot-verified.img from T1P2 FW for Magisk.

There is a newer version of T30 with an ID T1P4, but unfortunately the owners of this updated version haven't bothered to post their values of screen refresh rate/ touch samples per second or their experience in general regarding this issue.

For rooting, unlocking bootloader, TWRP custom recovery and GSI ROMs you have to check previous posts of other users, as I'm not interested yet.

Feel free to add/ correct any of those above.
[Android General] murigny64:
Open both scatters and compare:

Partition name, start address and lenght must be strictly identical.

If not, don't flash T1P2 firmware !
[Android General] NikosD:
I was thinking to take a backup of my current FW using SPFlashTool and IIRC I need a proper scatter file for that.

And since I couldn't find a T1P3 scatter file, I was thinking to take T1P2 scatter file.

Is there any other way to take a backup of my current FW ?
[Android General] NikosD:
My second charging of the battery and the red LED indicator is blinking instead of staying stable red during charging.

Battery looks like charging normally.

Usually this type of blinking means problem and it's only the second time I try to charge the battery.

Anyone else with the same problem ?
[Android General] arnarn911:
I also noticed that today. Im guessing its because of the battery level. It was under 30% when it was blinking while charging. Tested now at 90% and no longer blinking.
[Android General] NikosD:
The first time I let the battery go to 0% and power off the tablet.

During the first charging the red LED was stable.

The second time I didn't leave my battery to reach 0%, so I began charging at 8% and it was blinking as I wrote above.

I managed to solve the issue with just a reboot during charging.

So, although battery level was below <20 % while charging, after reboot the red LED was stable through the whole process of charging.
[Android General] arnarn911:
Yup confirmed red led light became solid after a reboot. Wonder what triggers the led light to blink.

How do I flash GSI?

So I got my tablet today it's a T1P3 device

Question is what steps do I need to take in order to install GSI on it and then root?

I would assume I'll have to install GSI first and then use magisk to root.

But looking at your instructions I am confused.

I never installed magisk, I assume I skip this step

Where do I find these, the device type does not matter? How do I flash them is I don't have magisk?

What do I use to flash and wipe?

I use linux and I have SP Flash Tool installed.

I can see the device in adb devices

SP Flash tool does not detect the device for now(still working on it), but I would still like to know the answer to my questions because I might do it from a windows vm
[Android General] murigny64:
[MENTION=2674307]tzeus[/MENTION], all operation are under TWRP.

So, you have to unlock your bl and flash TWRP first
[Android General] tzeus:
[MENTION=4599772]murigny64[/MENTION] Ah I see now. I was following up your post some time ago that unlocking bootloader is not needed. But it all makes sense now. I'll get on to flashing TWRP, it's safer anyway.

How about the zip files for orange state and encryption?

Thanks for the answers!

Edit: I found them earlier in this thread.

[Android General] Adamooo:
If you flash he gsi can you let us know if it resolve touchscreen issue, or the gsi it will use the same touchscreen driver?
[Android General] tzeus:
Sure thing. I don't it will solve the touchscreen issue as I haven't removed the foil from it. I will mainly use the tablet for media consumption and I have bought the keyboard as well, so less typing. I will post an update once I'm finished with it and let you know.
[Android General] murigny64:
No, it can't solve touchscreen issue, GSI change only system part.

This issue due to driver, witch is on vendor part.

[Android General] tzeus:
Quick update:

I managed to install Magisk, and rebooted to fastboot.

From there I installed TWRP which works, but it was asking me for the decrypt password, password which I had not set. I tried with password and default_password but these did not work. After that I tried to format user data, but that deleted my files from the storage.

I managed to use a combination of touchpad, screen and a OTG drive to flash

1. orange state disabler

2. flash DisableForceEncryption_treble

After this I did a factory reset and I flashed system-quack-arm64-ab-gapps.img to system partition

Flashing was a success but resulted in a bootloop. I did try to rename /system/bin/uncrypt but there's no change.

I suddenly remembered I should have removed the Magisk patched boot, so I did that and Android booted up nicely.

I am now running AOSP 10.

For those that are wondering touchpad and keyboard work in TWRP

I somehow managed to make the screen work(but just 1 time, I don't know how it was an accident)

After installing multitouch and screen info the conclusion is that the values are the same, but I think the touchscreen works a bit better with GSI but could be placebo.

[MENTION=5034664]NikosD[/MENTION] You can find a GDrive link reposted by me a few replies back. In there you can find TWRP, and the 2 zips I was asking about earlier. Basically they are for T1P2, but they work with my version which is T1P3(ordered from amazon - I think all of these are T1P3).

I'll update if I have any other news.
[Android General] NikosD:
After a few days on AOSP 10, give us your first impressions on that FW especially regarding bugs, working/ non-working apps, battery consumption and performance, if it's not a lot of trouble for you.

Do you have a download link for the specific AOSP 10 you flashed on your tablet ?
