Hi!
I 'm trying to push files to a samsung tab pro sm-t520 (n2awifi) that has the e-1.18-r-20231231-UNOFFICIAL-n2awifi rom on it. It used to have twrp 3.2.3 on it, and used it to push the rom zipfile to the sdcard using adb. That worked well, but TWRP disappeared after I installed this e-OS rom. So I 'm trying to push files with adb using the e-os recovery but I’m not succeeding 
I tried to push to /sdcard/ and also to /external_sd/ and at first sight this works. I can find the files using the adb -d ls /sdcard command for instance. BUT they are in a temporary folder (I guess), because once I reboot the tab the files aren’t being found by file manager.
Anyone point me in the right direction?
Grz!

I think within the recovery you need to mount the sdcard first on those paths. Without it will be the same filesystem as the / root
Thank you for responding. I think that I understand what you want to say, but I don’t see how this should be done.
There is an option that says ’ mount/unmount system’. I can click on it, but that doesn’t seem to make any difference. Can you provide dome more details on how to do it?
Did you already enable USB debugging?
You might try from e-Recovery > Advanced > Enable ADB before Mount / unmount system.
When successful the change is recorded at the foot of the screen.
what do you want to achieve? just for updating a rom “adb sideload” is an option and something the e-recovery supports
I would like to install Magisk and use it to install a module that adds a memory swap file to improve speed and stability of the android system

if you’re missing twrp, you can flash it with fastboot to the partition. Things should work™, if not, flash back the e-recovery
Thank you for suggesting this, aibd! I will try it later this evening. I 'm not in the near of my devices right now.In the meanwhile i’m asking myself how can i know how i should adress the sdcard?
Thank you for your suggestion, tcecik! I will try it if other options fail. A problem is that i can no longer find a twrp that is specific for the n2awifi. Someone at xda once made an unofficial version, but it’s no longer available for downloading. The link is dead… There is a version for the picassowifi which i think that i installed to install a lineageOS rom some years ago. Maybe it will still work…
are you coming from this thread? https://xdaforums.com/t/rom-samsung-sm-t900-sm-t520-v2awifi-n2awifi-unofficial-e-os-r-android-11-0-r-e-os-q-android-10-0-q.4649334/
it offers magisk’ed kernels in the “alternative downloads” links on mediafire
I’m no Samsung person, but looking at the specs of the two devices, I’d guess a n2awifi can boot a v2awifi recovery/TWRP - Download TWRP for v2awifi
I was able to install Magisk by just using the adb sideload method. (Commands: adb -d reboot sideload and adb -d sideload Magisk-v28.1.apk.zip) I did that by mistake. It wasn’t at all the way that is beïng described on the Magisk site. There it says that one has to push the boot.img file of the rom your device is using to sdcard and next make the Magisk app installing it. As a result it should create an installable zip that you have to pull back to your computer to flash it. After I sideloaded the renamed Magisk-v28.apk file, I rebooted the device and opened Magisk. The app stated that the installation had to be redone. It suggested a direct install as the recommended option. I choose that option and the rest of the installation process got done in a few seconds. So I’m good for now!
I will still explore the suggestions that were given here, but right now I’m concentrating on installing the swappiness module. I’l l get back to this threat in a while. Thanks again for the advice @aibd and @tcecyk !!!
