A30 firmware update from 1.35.56 to 1.37.xx problem?

[TheodoreMateo]

I'm unable to do a firmware update of my A30 printer from version 1.35.56 to any firmware 1.37.xx.

After updating mainboard and LCD the "Settings" section (correct the "Settings" button) didn't react to anything and the list of files in "Printing" disappeared (empty list).

In my opinion the SD Card reader disappeares for the printer after I install any 1.37.xx firmware (I'm on it because after the update of the mainboard no LCD update mechanism starts on the printer when I use the SD Card with the config.txt as update method, see below. That's only works fine with a 1.35.xx or 1.39.xx mainboard version).https://trackeasy.fun/usps/ https://showbox.tools/ http://essaywriter.fun/

Maybe a driver / hardware version problem with firmware 1.37.xx?


My A30 Hardware Version: V2.1-null
Serial number: 180708A3001562A
I've flashed the firmware with the Updater Tool 1.2, 1.1 and 1.0. Also tried the combination with LCD update via SD Card (config.txt and system dirand mainboard via Updater Tool. Also I think I tried any way of doing the update, some tries with _S_ as and then _M_, some updates _M_ then _S_ and any combination with the working firmware versions as update base. Also a lot of factory resets done.


Which version's I tried and failed:

A30_M_LCD_V1_37.bin
A30_VD_S_V1_58.bin

A30_M_LCD_V1_36.bin
A30_VD_S_V1_57.bin

Both version's I tried with a local file and the remote function of the Updater Tool 1.2.


These version's are doing as expected:

A30_APP_M_V1.39.62.bin (as developer version from Geeetech via Updater tool)
A30_APP_S_V1.39.62.bin (as developer version from Geeetech via Updater tool)

A30_APP_S_V1.35.56.bin
A30_APP_M_V1.35.56.bin



Maybe a hint for Geeetech Guys: EasyPrint 3d shows a printer firmware version "1.xx.58" (or .57, really ".xx.", not ".37."), on the LCD I'm unable to show the Info section because I can't enter to the settings menu..


A reflashing back to the older firmware versions works very well - and get's me all fixed bugs back..


Anyone have a clue?
