I just downloaded the firmware from SamMobile (free, but requires registration). I got out of the Odin boot loop and to the language screen now, so that’s good 
I used Odin v3 and the BL, AP and CSC_OMC_OXM files.

Since I can’t use Odin and TWRP I have tried to make a package for Heimdall, but I cannot seem to get it right. I am not that technical and the instructions are not clear to me.
What does 1. Setup a MinGW-W64 build environment by utilising MSYS2: http://msys2.github.io/ mean? The explanation on the Github page makes no sense to me 
I think we need to up the clarity of the texts so anyone can do this. It was quite easy to get eOS up and running on my Mi10T.
I just wish /e/OS easy-installer worked for samsung tablets too.
What issue do you have with Odin and /e/ recovery?
You cannot use TWRP anymore as it results in an error and you get stuck in a boot loop. Just search a bit on the XDA forums. It is the case for several Samsung models, at least.
I am required to build a Heimdall package for Windows, but I cannot seem to do it, which is the only alternative I know of on Windows.
This is the reason I ask you about /e/ recovery which is linked on the page I first sent (unless you are using a different device, which is unconfirmed ! )
An (untested by me) Heimdall package for Windows is mentioned in LineageOS wiki, for instance this totally unrelated device Install LineageOS on beyond1lte | LineageOS Wiki
I have the S6 Lite (SM-P610).
TWRP for that unit is no longer updated and therefore results in a boot loop - so no use for Odin. I tried to build Heimdall myself, but was unsuccessful. I really do not understand what I am doing wrong.
Thanks! I will try the package and see if I can make it work
No luck…
" Windows: Extract the Heimdall suite zip and take note of the new directory containing heimdall.exe. You can verify Heimdall is functioning by opening a Command Prompt or PowerShell in that directory and running heimdall version."
It does not manage to find Heimdall, even though i Ran PowerShell from the directory it is in
I do not have a Windows machine to demonstrate this, but you are likely to need to:
cd /path/to/Heimdall
./ heimdall.exe
The ./ tells your PC to operate in this folder.
Follow @Marine she had give you the solution, TWRP is unfoundable OK but recovery-e

I am currently stuck at this same point, but on a Galaxy S10e Exynos. It looks like there’s hope though, thanks @StigtriX for the SamMobile link to get out of the Download Mode bootloop.
And pre-emptive thanks to @piero & @Marine for what looks like the next guides I’ll need. (Although I did manage to use Odin to downgrade from Android v12 to v11)
Please let me know if there are any other pitfalls I’ve overlooked.
Really good tutorial! I created a German translation: [HOWTO] /e/OS auf einem Samsung-Smartphone einfach installieren

I’m stuck and very frustrated. I’ve tried three phones so far and I’ve reach a road block on all three…
I was able to get eOS on a S4 mini, but no US carrier would provide service…something about it being a China phone. So I bought two (2) more Verizon-branded editions of the S4 mini, and I can’t even get eOS installed. One won’t even update the built-in OS. The other is Android 4.4.2, but I get stuck at the same spot on both…OEM unlock doesn’t appear in the menu (yes I enabled developer options), fastboot and heimdall don’t seem to recognize it when plugged in, (but adb will), Odin failed to install twrp…
What’s going on? Is Verizon F’ing me? What do I gotta do to get this to work?
Hi @concretebox welcome to the /e/ forum.
Verizon is a bootlocker. If the phone is branded Verizon this is highly likely. Samsung phones with locked bootloader display Prenormal on the Odin mode (Download mode) screen.
Well…I got it Rooted…twrp won’t install via odin though…say Fail.
welp i just f’ed it all up…used adb shell to dd serranoltexx into the /dev/block/platform/msm_sdcc.1/by-name/recovery…when I restarted the phone displayed a message “unauthorized software installed, power off your phone and contact your verizon store.”
Is this what “bricking” is? Does this mean it will never work and I’m F’ed again?
So is it Prenormal or is it not?
That is not bricking; the device is still talking to you!
@aibd - Thanks…I’m new to this so the terms are confusing me…
I don’t see the word Prenormal anywhere…I’m looking on the phone and it says:
ODIN MODE
PRODUCT NAME: SCH-I435
CURRENT BINARY: Custom
SYSTEM STATUS: Custom
CSB-CONFIG-LSB: 0x30
BOOTLOADER AP SWAEV: 4 (really hard to read this one)
WRITE PROTECTION: Enable
Lower down is says “Downloading… Do not turn off target!!”
On the PC Odin says:
<ID:0/015> Added!!
and nothing else.
So the bootloader is not locked. Two lines of “Custom” indicate it is not Samsug Official.
I guess it is now what Verizon is up to. I am in UK and have no experience.
You might try searching for the bootloader term you are struggling to read.
BOOTLOADER AP SWAEV: 4
Maybe Verizon require a special situation to allow the Custom ROM to become authorised. Just a guess, but that expression I have not seen before, sorry.
Sometimes we see a disabler for a situation like this.
humm…after a few more restarts now it won’t display anything other than the “bring this to verizon store” message.
So…not bricked but just as useless?
