Raspberry Pi4 3.5" touchscreen help

[vong]

Hi all,

 

Just got a Raspberry Pi4 with a 3.5" touch screen and cannot get the damn thing to work. I followed the guide given by the seller and keep ending up with a rainbow screen after reboot and it's driving me mad since I have to reflash the SD card all the time. What's the deal? Seems like the commands worked as they should.

Which model and manufacturer is it? I bought the one from Jun Electronics, and they supplied instruction how to get the drivers or, if that fails, an image of the OS with their drivers in the Amazon page.

Give it a try even if your model is different, I think those cheapo screens are pretty generic.

Just copypasting that here (it's in Italian but should be straightforward to decrypt):

 

Passaggio 1: installazione del file immagine ufficiale Raspbian:
1. Scaricare l'ultimo file di immagine Raspbian da
ufficiale 2. Utilizzare SDFormatter per formattare la scheda Micro SD
3. Utilizzare Win32DiskImager per masterizzare l'immagine ufficiale sulla scheda Micro SD

Fase 2: Connettere lo schermo con Raspberry Pi

Fase 3: Installare il driver a Raspberry Pi Review 1.Prepare tastiera e mouse per Pi, connettere internet.
2. Esegui i seguenti comandi
sudo rm -rf LCD-show
git clone https://github.com/goodtft/LCD-show.git
chmod -R 755 LCD -show
cd LCD-show /
sudo ./MHS35-show

Se hai difficoltà a installare il driver, o se ancora non riesci a utilizzare il display correttamente dopo installando il driver, prova la nostra immagine del driver di pre-installazione per il test.
