Sorry for the silence. I was on vacation. I will try to do "fastboot oem device-info". And one more thing: here is an interesting link - https://forum.xda-developers.com/co...me/lenovo-smart-clock-bootloader-avb-t4130295. Maybe it will be useful.
P.S.
I tried to load in recovery mode JBL and Lenovo - only picture with Android like in demo version JBL.
And here are responds of fastboot commands from Lenovo Smart Dysplay:

I tried to open JBL. Inside there is a regular motherboard with Wifi and BT modules and antennas. Also on the board there is a button and near contacts RX, TX, GND. I could not the column completely disassembled. I could not separate the screen and speakers. Therefore, the motherboard could only be seen through the hole. see picture :

All you need to do It’s just purchase a replacement logic board for whichever version you have then take the speaker part and replace the logic board and you’ll have a functional speaker here this is a link to the JBL link 300 logic board just to give you an example

https://www.ebay.com/itm/324016733315

In all honesty though these devices are not simply demo models that can’t be taken out of their current state their actual devices which were meant for sale that the stores that bought them probably get instructions from JBL on how to place them in demo mode it’s honestly going to be some combination of buttons being held down for upwards of 30 seconds try everyone you can. Stores don’t really produce like the demo models anymore they just have secret methods that they don’t inform the public about and instead inform retailers but these devices are identical to the ones that are sold normally I’ve stripped them down and seen both of them edit it’s not a locked firmware it’s just a locked mode that it’s in with no clear instructions on how to get out as of right this moment

Start with holding volume up and connect for as much is a minute without releasing it


Do You Have the Seller's Link who is Selling the 'Main Circuit Board' for 'JBL Link View'…? 🙏🙏🙏

Maybe we should use the contacts RX, TX, GND I wrote about above to connect via adb. But to get to them, we need to remove the screen. The screen is attached to the body with glue. But it's not a problem.

You have to remove the rubber band at the bottom of the case and unscrew the screws. This is for removing the bottom cover. Then remove the speaker grilles by prying them off with a plastic card. There are screws under them - they also need to be unscrewed. And then the most difficult thing - with the help of a hair dryer, you need to heat the display and carefully remove it. There will be screws under it too. They must be unscrewed and the panel removed. The panel seems to be attached to the body with snaps.
I haven't taken the last step yet - I haven't removed the display and bezel yet. If I knew what I need to do next with the motherboard, then I would completely disassemble smart display.

Excuse Me,

I have Already Removed the Rubber Band at the Bottom of the Case, and also have Already Unscrewed the Eight Shorter Screws & the Two Little Bit Longer Screws, and then I have Already Removed the Bottom Cover Smoothly…… 👍🏻👍🏻👍🏻

Now the Question is How to Prying the Speaker Grilles Off by Using A Plastic Card, Sir…? 🙏🏻🙏🏻🙏🏻

    Today I accidentally erased the system partition via Fastboot. And now it doesn't show the demo clip. This means I need to load the system.img into it . But how to pull this partition from the working device - I don't know yet. I keep looking for a method. I think JBL use Snapdragon 625 APQ8053 and Android Things OS. If I could get developer mode I would use ADB to download system.img from working device

    I've got a working Link 10 if anyone can point me in the right direction. Is the firmware/hardware the same? How could I copy it without blowing up my Speaker.... ??
