Hi . I am trying to recover a nextion NX4832K035_011 from a " System data error" which occurred when,
while downloading a project to Nextion our power grid went down.
I have a micro SD card and reader but what do I do next?
Thank you

Hi and welcome @Farticus!
Usually you can solve this sort of issues by taking an SD card with any TFT file (that matches your device), plug it in, power it up, and it should just load the file from the SD card, replacing anything corrupted.
It is important to note that in such cases the screen tends to refuse known good SD cards. So you should definitely try a couple cards if one doesn‘t work (even if it previously did).
Serial update usually does not work.
Kind regards,

Tried 3 sd cards
Formatted sd cards before transferring TFT file
All said “model does not match
NX4832K035-011R”
The black board model on the left is an ENHANCED (notice “K” in model number)
The blue board model on the right is a BASIC (notice “T” in model number)
You’re probably trying to load BASIC firmware onto the ENHANCED.
Do this -
Download the Nextion Editor
Start a new project for a 3.5" Enhanced
Go to the 1st page and in the pre-init tab add the following
dims=100
bauds=115200
cls RED
Click COMPILE
Click FILE > TFT File Output > OUTPUT
Drag this new TFT file to your SD card and remove and other files from card
Power OFF Nextion, Insert Micro SD card and Power ON
This should load the correct firmware from the micro SD card and allow future serial uploads
Thanks Mate. Worked just fine.
Really appreciated
