Problem with adb sideload vs. Developer Options

Hi,

We have no less than four Samsung SM-A520F phones in our household, all running /e/OS. Unfortunately there are no more updates for the a5y17lte build. I found an unofficial build here in this forum, so I downloaded it on my PC.

Now I had no problems replacing the old Android system on this phone with /e/OS. I even described the procedure in detail on my tech blog.

Right now I seem to have trouble getting ADB to work under /e/OS. I tapped seven times on the build number which activated the Developer Options, and then in these options I toggled DĂ©bogage USB (french for USB debugging).

I connected the phone to my PC but unfortunately adb devices shows me nothing.

The documentation states something about OEM, but there seems to be no OEM-related option whatsoever in my Settings.

Which leaves me clueless. Any suggestions ?

PS : just wondering… is there any way to simply update to the unofficial build from within /e/OS without using ADB ?

yes,

  1. copy the zip to a SDcard or in the phone “internal storage”,

  2. boot the phone into recovery mode
    Boot Recovery Mode on (a5y17lte)

  • With the device powered off - hold Volume Up + Home + Power
  • In android R 11 : → settings → system → advanced → gesture → power menu → advanced restart
  1. then depend of the recovery manager installed on the device :
  • TWRP : use the install feature navigate to where the file is stored
    SDcard is located at /external_sd, when “internal storage” is located to /sdcard
  • recovery-e → apply update → choose from sdcard1 or → choose from internal storage
    navigate to where the file is stored
    SDcard is located at /external_sd, when “internal storage” is located to /sdcard
    on some models the recovery-e don’t have this feature in this case, replace it with TWRP

Thank you for your prompt answer. In the meantime I fiddled around a bit more. I was surprised to see that ADB worked perfectly on my girlfriend’s phone, which is the exact same model. So I tried a different cable, and now it works perfectly with ADB.

TWRP offer fantastic features…
also, when installed, you don’t need a PC anymore when updating or trying another CustomOS

on recent version of /e/OS, there is a “local update” feature in the → settings → system updater
