You can ask someone to make a backup of the desired partition from the work device. And then upload it to your tablet. The main thing is to know what exactly you need

As I wrote before, firehose from TB-J716F fits our tablet with the name, 29-11-2022_19-32-13_prog_firehose_ddr.elf
Clearly understood about it.
*Just pretend it as a rumor*
Yet I recently came across some random reply, claiming that they'd swiped the ROM into crDroid and worked perfectly fine
; though I can't find such firmware of corresponding model under the Lenovo family on the website.Inspite of that, I think that installing the custom, stable ROM alike crDroid for TB138FC-SD870 is feasible in the coming future, right?

Frankly, I didn't feel much different but possible stability and more recent security update.
Good news!
The beta testing of the new firmware has begun.
The main testing is on the new PC Mode.
I wonder if they are willing to upload the full ROM package for us, or would it just incremental package just like before? Even I really need an official full ROM package when things go wrong, like in my case, I did send my device back to the Hong Kong store where I bought it. My device just won't get turned on anymore, so the last option I had to do was claim a warranty. It s*cks that I have to pay for the delivery fee. But I hope it can fix the issue.
If I encounter the same error, then I wouldn't want to buy a Lenovo tablet anymore
; I will use Xiaomi again since they give more support and transparency on their ROM package (it can be accessed publicly).Could you tell us where we can get this kind of information or any related community for ZUI updates?
So far are not sure how the update will be. But if it is still ZUI 14, I bet it will be incremental.I wonder if they are willing to upload the full ROM package for us, or would it just incremental package just like before?

But if it is ZUI 15, I'm pretty sure it will be full ROM.
Let's wait for the official and I will copy the update package file to host in cloud for you.
I just bump into their Weibo official account time to time and saw that info. If you could read Chinese, you could go in here.
After all, on the screen you can see that it is unfortunately ZUI 14
I really appreciate your informations, I hope they'll soon release the full ROM package when ZUI 15 release, so user can fix the immature software issue by their own.
I wasn't expecting that Lenovo is more less put attention about this one, which in Xiaomi brand will give better support regarding ROM package (maybe it's because from the beginning, Xiaomi focusing on their mobile products).
Since they are already promoting ZUI 15, we might not be far from it.
However, as I red from the Chinese forum, they said that ZUI 14 feature was fixed to have no PC mode when attached the keyboard. This will not change.
Unless ZUI 15 might had include that. So, hopefully this is true where we are expecting ZUI 15 with PC mode by the tablet itself.
I'm checking ZUI14 OTA news letter for other tablet and seems like they are enabling the PC Mode and side shortcut bar. We might expecting that for our tablet too... Let's wait for the new OTA... Soon...
Great news!
I got my OTA today and I'm using the PC Mode with my keyboard attached on the tablet, by the tablet, to write this post.
You will get yours very soon. Or you could download the OTA file here and update yourself.
