When I did my first connection to the NSPanel to internet the update file was downloaded in the root folder. You need to copy that file to a computer and later do the update.
The sonoff will request to reboot when the download is done, that is the moment to extract the update.zip.
Later you can proceed with the update normaly.
I manage to factory reset(by switching on and off for 5 times) multiple times but every time I end up with same firmware 2.1. Is there anything else I can do to downgrade the firmware?
I hit the same issue and was able to solve it.
After running the flash-script.sh install script I got the expected success message

Hi All!
This might be a stupid question.
I have updated webview, and installed companion app,
Everything works great.
I have one problem though - and that is the screen never goes to sleep.
i first thought it was the nspanelTools, but even though i disabled that - it still doesnt go to sleep.
under display settings advanced i have set it to 15 seconds.
i can “trigger” it by sending the power_off key via an ADB command
but i would really like for it to simply turn of the screen when it’s not in use.
please notice that i did remove some of the standard apps - so i dont now if that is part of the reason.
help is very much appreciated.

I am looking at getting one or two of these to use as HA dashboards for bedrooms where there is a fair amount to control per room.
The thread is fairly confusing, however am I right in thinking this method should still work with devices that are purchased today? Or have Sonoff now locked the device down so it’s not possible?
I got one a few days ago and have just finished the setup. I confirm that the steps in this guide are still valid. Here’s my experience:
I think on newer firmware the update of webview is not really necessary any more?
do you have a step by step guide how to upgrade the firmware as I can connect to the unit via adb but then how do you upload the new firmware as I am stuck on 1.5 would like just to put it back to stock firmware
how do you upload the zip file ?
Since I seen a few questions about firmware updates after enabling developer mode, I thought I share, since I managed to do this successfully using seaky’s root tool today
Download and Install the Root Tool
https://github.com/seaky/nspanel_pro_roottool_apk/releases/tag/v1.0
adb install nspanel-pro-roottools-1.0-release.apk
Download the firmware, I found 1.7.0 here and upgraded from 1.5.6
https://drive.google.com/drive/folders/1bHLLJy8vYUjkCCnyUmrHgEFWi_2cxywv
(If anyone has a newer release, please post)
Make file system writable (not sure if this is necessary)
mount -o rw,remount /system
Copy the file onto the NSPanel Pro
adb push <path to file> /storage/emulated/0/system_update.zip
Open the root tool in the NSPanel Pro, click verify and install if the file is good.
This procedure worked for me, but of course no guarentees and to be done at own risk.
Sonoff firmware V2.2.0 (10-nov-2023) and V2.0.0 (12-sep-2023) added Zigbee router mode and Matter support:
@seaky does not recommend to upgrade firmware above 1.5.0 because Sonoff removed a tons of usefully binaries from system folder. However, with the new functionality introduced by Sonoff, I’m wondering if it would be possible to combine the best of both worlds (HA companion app + the zigbee router/matter functionality) OR is better to stay with version 1.5.0?

I founded how to enabled the developer mode
Thank you!
Hello, I have an nspanel pro, and I was wondering if it has been possible to use it as a tcp coordinator for ZHA?
Hello, how did you do that ? Activating it through eWeLink app by hitting Device ID 8x asks to enable Developer Options, but confirming that does not seem to unlock the panel anyway and I still hit the wall with connections being actively refused. No luck via usb either as adb device is not listed despite being seen in Device Manager as px30_evb. Any hints, please ?
and hint is obvious - read the instructions 
I now know that I need to enable adb as an extra step !
