Hi folks,
i’m currently have a CPE outdoor unit sold by Telekom (DT5GR2A).
This unit looks like a module with RTL8125 PHY with some customized stuff inside for the WebUI and APN provisioning interface. I have access to the unit via ADB and the partition layout looks like a stock module:

I want to know if it’s possible to replace their “crappy” firmware with a stock FW from Quectel module.
This is the current version installed (very old and also beta…):
Quectel
RG520N-EU
Revision: RG520NEUDBR01A04M8GA_OCPU_ACY_BETA_20221115C
Thanks in advance
