There is no difference in the final resulat. Both methods will install TWRP on your Samsung phone.
It’s true it’s not mentioned directly in the installation page of Samsung devices, maybe it should since this HOWTO seems safe a tested by many users.
No, I don’t know any problems of this kind: Wind°ws and “Odin 3” fit together as well as Linux and “Heimdall”.
The majority of “professionals” especially software developers use a Linux derivate and have already given up using Wind°ws a long time ago. Wind°ws is as reluctant to be put into the mouth as G°°gle. So tools are primarily mentioned on Linux basis. They simply “forget” that 3/4 of the “normal” desktop PC / notebook users work with Wind°ws as operating system. An effective Wind°ws tool is Samfirm, a fast free downloader of Samsung Android firmware.
I belong to the Wind°owsers of the first hour. My W°Systems are largely “closed”, so that it can only rarely “phone home”
Good point. Will have a reference to installing Odin also added to the official /e/ documentation.
That’s brilliant. I remember when checking out /e/ for the first time the Samsung instructions looked like a big hurdle, so I only looked at Motorola. Samsung being the most ubiquitous models, it should be as easy as possible for Windows users.
Hello, I installed a Samsung S9 via this method. Worked like a charm and today I tried my luck on the Galaxy S7. No luck this time. I bricked it twice but via Odin I could bring it back to the original Samsung installation. The problem actually was not Windows or Odin related but the phone seemed to be encrypted. In case of wiping as written in the article do this:
Boot into TWRP after the upload to the phone
Choose the button “Keep Read Only” It seems to me that the Galaxy S7 had encryption on by default.
Choose the “Wipe” button
Choose “Format Data”
Type: “yes” and now everything is wiped off the phone
Reboot into Recovery and choose “Do not install”
Choose “Keep Read Only”
Now you can go on with the installation of /e/
Everything went well
Thanks for the nice manual! I trying to use this ROM for my Galaxy S5 Mini (kminilte).
Everything works fine for me until the flashing process.
I am encountering error 7. While I could avoid the device check with the above posted infos, I now have a new error 7 which is the following:
Patching system image uncondituonally...
mkdir "/cache/revovery/
19e673c[...]/" failed:
No such file or directory
E1001: Failed to update system image.
Updater process ended with ERROR: 7
ERROR installi zip file 'e9.zip'

... done
Maybe somebody has an idea?
Hi, welcome in the forum 
Which version of TWRP do you have ? The error 7 happens on old version of TWRP, like 3.1.1 for instance. Last version is 3.3.1 (if my memory is good enough).
Oh a 3.4.0 version was released 3 days ago and is available for your device.
Thanks, and thanks so much for the fast reply!
I am using twrp-3.4.0-0-kminilte, so I guess that is not the problem.
OK, I wanted to install /e/ on another phone (Samsung A5 2017, a5y17lte) which resulted in the same error. Finally I just tried so previous TWRP version 3.3.1-0 which worken like a charm on both devices! So I would recomment to abstain from using 3.4.0 for these two devices!
All right, thank you for the tip !
Thank you so much. I had a similar problem installing /e/ on my Samsung J5 and using the TWRP 3.3.1-0 instead of the 3.4.0 solved my problem.
Very helpful comments @izgrimmer @Anonyme:
Had the same Error 7-Problem with a Samsung Galaxy S8 and TWRO 3.4.0. With the TWRP 3.3.1-0 it was no problem at all.
Thanks @Anonyme! I did the flash with your tut and worked well. Way easier than the e tut. I had only troubles that I couldn’t put the zip file in to the internal storage, I put it instead on a micro SD and bootet it from there, merci encore une fois!
Hi everyone
After multiple attemps on my Galaxy S8, I still had the Error 7.
Solution found: add a reboot of Recovery TWRP without install (no install option) after wiping your cache, data, etc…
If you had to reformart and back to ext4, then I’d add another simple reboot of Recovery without install.
I’ve tried to remove the asserts line (de-zip re-zip the ROM) but it didn’t change anything.
I’ve tried Lineage 16 (same error 7) then Lineage 17.1 (different error this time).
The next day, after a complete reboot (with no install), the installation of the latest e/Rom worked fine.

I used
TWRP 3.4.0.0.
Odin v. 3.14.4

Rom: e-0.9-p-2020062560240-dev-dreamlte

Thanks a lot @Anonyme. It’s a very clear guide, even for an (absolute) beginner like me. I have bought a device with pre-installed /e/ because I thought I wouldn’t be able to do learn how to flash myself in the near-to future. But as I really like the idea behind /e/ I am keen on learning more. So with the help of your “How to” I flashed my old S4 mini. And it worked - which made me really happy!
I used TWRP 3.3.1. as recommended by some in this thread (instead of 3.4.0) and had no Error 7.
One small question: In the “How to” under Point 8a (Delete existing smartphone content) it says: “Select the following items to delete and nothing else”. The following 5 bullets include “Internal storage” which is however not ticked on the screenshot (and I think I also read somewhere that “internal storage” shouldn’t be deleted). Is that a small bug in the description? (I opted for not ticking it)
Thank you, that was the goal 
In the first place Internal Storage wasn’t mentionned (because at the time I also read that I shouldn’t tick it), but I tick it each time I need to wipe and there is no problem, so I added it but I haven’t modified the picture.
Internal Storage is just what you can find in the Files app (“Download”, “Documents”, “Pictures”, etc.).
Thanks for the additional info @Anonyme. I deviated from your procedure in a small way: I already had transferred the /e/ ROM zip file before installing TWRP (somehow thought that could be safer if for some reason my phone would not be recognised as a device in windows afterwards). Just to be sure: In this case it would have been deleted if I ticked “internal storage”, right?
By the way, is it important to place the /e/ rom zip on the internal storage or is external SD card fine too?
Yes it would have deleted the file you put into the internal storage. So in this case you did well by not ticking it
My 2 cents : I had several issues with the latest build of TWRP and the fact is that it want to write in an non-existant directory when you want to install the zip file :
/cache/recovery/xxx
The workaround to complete the installation with this build of TWRP is to go to Advanced / Terminal and type :
mkdir /cache/recovery
Then go back to the installation of your zip file
