I used to have big hard disks. Since then, I have reviewed and think harder about my real needs.

I have realized that 2 ssd (much faster that hard disks) of 1TB each are sufficient.

Sell your hard disks (if you can find a buyer!), buy smaller ssds.

So I'm trying but I'm loosing with this ****ty Unisoc.

I got stuck at latest step - unlocking bootloader.

I have all the files from the Hovatek's archive, nothing was deleted, but still I got this:

error: could not load 'unlock_bootloader': No such file or directory

Any idea? Anyone had similar problem?

ADB and Fastboot work fine, so all the udev rules are fine. Tried with sudo, without, after sudo su, "fastboot" "./fastboot". Nothing helps.

EDIT: Ok. Found Abatoir's post on 5th page in Hovatek's thread. Setting every file as read&write and executable did the trick. Now I'm unlocked.

[Android Q&A, Help & Troubleshooting] xXx yYy:
You compile Teclast P20HD compatible TWRP at your own.

To install created TWRP, you use the Spreadtrum Flash tool.

To root Android, you flash Magisk by means of already flashed TWRP, then install SuperSU via Magisk Manager.

Prerequisites:

SPD Flash tool ( the official flash tool provided by Spreadtrum Communications Inc. )

Spreadtrum USB Driver

Teclast USB Drivers

Note: There is no need to install adb and/or fastboot drivers on Windows PC, they are not used.

[Android Q&A, Help & Troubleshooting] ch3mn3y:
Love autocorrect. There supposed to be "to new Android", coz since 9 some devices needs to resign vbmeta. Didn't have to do it with my Realme, but here it is needed.

Tried already, and not only me, what You write and with patched image Your device won't boot. Not because of the image, but verity. And for that we need modded vbmeta.

I have one, but now I need to resign boot.IMG, but that gives me error. And I'm not too much into Python, so even off I know what is the problem I don't know why is showing and how to get through it :(
[Android Q&A, Help & Troubleshooting] kogepan:

[Android Q&A, Help & Troubleshooting] ch3mn3y:
We could flash TWR0 if we had one.

Boot image isn't started coz of signature mismatch.

One question, how to boot to recovery? Stock one..

I managed few times to boot to recovery but would like to be sure how I did it..

Power+Vol-does nothing, Vol+ boots to test mode

I use

adb reboot recovery
[Android Q&A, Help & Troubleshooting] ch3mn3y:
Cos you can access the OS. But think about when you are in bootloop. No ADB for you. In recovery mode there is an option to boot to Fastboot and make the tablet work again. But without access to recovery mode you are screwed.

Could you tell me, please?

edit: Finally, is it possible to use adb root on this device?
[Android Q&A, Help & Troubleshooting] :
Since it runs Android 9 command "fastboot flashing unlock" is a correct one, unless it's not supported on phone what I don't know

Command "adb root" restarts adbd ( the ADB daemon located in Android OS ) in root mode - what only works on a rooted Android

Hint: Start a new thread related to your P80X device
[Android Q&A, Help & Troubleshooting] few__:
Unisoc devices generally require special means for Bootloader Unlock...

And to use adb root, I think you'll need to edit the prop or flash Rom separately...

And if you can't use TWRP or magisk, then you can't run these guides, can you?

No, it's not. I'm using a translation service, so I apologize for the difficulty in getting your meaning across.

I would like to know about rooting on the P20HD.

This is done by Fastboot.

simply changes 2 bits in the passed <VBMETA.IMG> as shown next

If not already having done yet, you have to install on PC the Spreadtrum related USB-driver as first thing of all things:

Then you have to install the latest ADB & Fastboot drivers provided by Teclast for this tablet:

Contact Teclast for this - I couldn't find them via a Google search. :D

Finally when you got the suitable ADB & Fastboot drivers, you can run any Fastboot commands as needed on the USB-connected tablet from your PC .

Hard Brick

Hi there !

I don't know how easy it could be with mediatek, but I had to do the battery trick (first time I open a tablet) to recover from an incomplete flash. I did'nt understand we have to

KEEP VOLUME (-) BUTTON PRESSED DURING ALL FLASH PROCESS

Better secure the button pressed with rubber band.

When I first revived my tablet, the update went in loop. Very hard to stop it at the right moment. I had more luck after checking the "power off when finished" option. (I used the flash tool coming along the EEA 1.0.2 version, it is a modified version of SPD flash tool R21)

Knowing this, I hope you don't have to know the following.

Quick disassembly guide for noobs like me :

First, remove SD/SIM tray.

This device can be opened by inserting sharp plastic tools between the two plastic pieces. The black plastic surrounding the screen is the chassis. On this chassis is clipsed the cover, composed of a plastic frame and an unamovible metal plate.

I believe the best place to start is over vol- button, also the jack corner seem more loose than other corners.

The battery connector is under the long tape, buttons side.

The spreadtrum battery trick :

-unplug battery

-secure vol- button pressed

-plug USB (the software is already running)

-plug battery

[Android Q&A, Help & Troubleshooting] santosst:
Thank you very much, man! This information is really good :D

Project Treble is a standard created by Google to organize system files, separating device-specific libraries (which are on vendor partition) from the main system (which is on system partitions). Look this site for more information: https://www.xda-developers.com/googles-project-treble-modularize-android-so-oems-can-update-devices-faster/

Therefore, even if Teclast does not release system upgrades for Android 11 or later, it will be possible to update this tablet using GSI ROMs that are compatible with Treble, like these: https://github.com/phhusson/treble_experimentations/wiki/Generic-System-Image-%28GSI%29-list

For now it is not worth using Treble, as Teclast can still release new updates, but as soon as they do not release anymore, this is a very good way to keep the system up to date.

Just give it a try on my phone running latest fw (android 10 one ui 2.1). Managed to have it up and running and working just fine EXCEPT call logs and sms / mms. It always says XML backup failed.

Is it something can be fixed or just the limitation of the app on android 10?
[Touch Diamond, MDA Compact IV General] harker_p:
I had this problem ages ago with my c500 and fixed it but cannot fix it with my diamond.

When a person calls - their name (and pic) appears as the person calling. Yet for 1 number only (it happens to be my gf) it comes up as the number only - and once the call is over it says 'number is not in contacts - would you like to add it'

I thought the fix would be to have both style of numbers (with +44 and without) in the various contact fields but to no joy.

It's annoying in the fact that it works for every other contact just not her! (maybe it's a sign!)

Any clues?
[Touch Diamond, MDA Compact IV General] L o r d R a j:
Long shot

Try this.. (assuming that you sync your phone with outlook)

Delete the contact from the diamond.

Edit the contact in Outlook with the contact numbers and assign a pic in Outlook itself.

Sync

See if this works.
[Touch Diamond, MDA Compact IV General] harker_p:
I've tried it - still no joy. I've checked to see if any other number exists in the phone/outlook that is too similar but I can't see one. I'd read somewhere that it uses the first 7 digits for caller id - and that number is relatively unique.
[Touch Diamond, MDA Compact IV General] L o r d R a j:
hmmm

While we are trying stuff out

Delete the contact from the diamond, anyway. In the call list / history.. you should have the a received call from your gf's number.

Save it from there. Then assign a pic.

Let's see if that works.
