Hi @lionel.smith
For my accompaniment during the install process, I am refering to the structure of the F***ing official documentation :
(Install /e/ on a Samsung Galaxy S III (International) - “i9300”)
You can have a look to this great How To too, but it is for another device and fastboot command don’t works for the Samsung devices.
Download /e/ for i9300
The lastest (nougat) /e/ dev image .zip for the i9300 ROM
Also download the Blokada ads-Blocker .apk
and copy them on the root of you SDcard
Requirements
don’t insert SIMcard, don’t connect the device to the WiFi for the moment.
- You don’t need /e/account for the moment
-
- Enable Developer Options and ADB usb debugging
-
Preparing for installation
-
The bootloader locking feature was added by Samsung later than the s3 release, so no problem with this first step.
-
you have to build “Heimdall” as it described here :
(Build Heimdall)
-
-
-
-
-
- disconnect the USB cable for rebooting
Installing a custom recovery
- re enable ADB in the Developer Options
- You need the .img file not the .tar
-
-
-
-
-
-
use TWRP, to create a backup of your Samsung Stock ROM, select of all the partitions
Installing /e/ from custom recovery
For this last part, you can have a look to this other great HOW-TO too, for Samsung devices, but the beginning is for windows
But easier is to install the zip from the SDcard than using sideload method

- easier is to install the zip directly from the SDcard using the install feature in TWRP, than using the sideload method
-
don’t insert SIMcard, don’t connect the device to the WiFi for the moment.
final settings
don’t insert SIMcard, don’t connect the device to the WiFi for the moment.
- now with the file manager, open the blokada.apk file copied on your SDcard to install this ads-blocker application
Because of “mum and dad” target, all the mainstream apps have to work on /e/, for that compatibility, nearly all doors are open by default.
So when I install an /e/ ROM I have to check many settings :
/Settings /MicroG ( if not, the device go to Gogol house on fist internet connection for IMEI registration to say good bye )
/settings /apps /data usage
/settings /apps /permissions
even for system apps
/Buttons (for comfort, not for security)
/Privacy /Privacy Guard menu advanced
Even for built-in apps
Add Blokada, launch the apps step by step for setting rules (I prefered if it block outing by default and ask what to do)
Even that, I may forget somethings because I’m not security expert.
.
now you can insert a SIMcard or connect the device to the WiFi…

Tell me if you are stuck or lost somewhere
