I go to sleep early these days at 8pm, but up with the sun, but years ago when doing tech stuff I would be up 2amā¦ my wife use to say she was a computer widow 
:)))
Please try adb sideload e-latest-star2lte.zip
I really am not that tech-skilledā¦ just 32 years of hacking at tech like today, so learned a lot along the wayā¦ but sometimes even simple things I dont know how to doā¦ so when you say the above, ADB sideloadā¦ if thatās via terminalā, then I dont know how
I see ADB is installing software and I see it in the advanced menu in eReceovry on the phoneā¦ can I do it from the SD card if I put it there ?
Is this a terminal command from WIN Terminal, while phone is plugged in, in D/load mode orā¦ ?
Not all custom recocery can load adb sideload from SD card.
No, not D/load mode - but normal system level - which is currently not present on your S9+.
I am trying to find a terminal app in WIN 10 and can not even find it hahahaā¦ dear meā¦
Procedure:
S9plus :: eRecovery > Advanced >>Enable ADB
PC Terminal: adb sideload e-latest-star2lte.zip
How to Install ADB on Windows, macOS, and Linux
Done !!
But I dont think there is a terminal app even installed yet on my new WIN 10 installā¦
Okā¦ I will download the ADB Tools, install, read up and get back to youā¦ THANK YOU SO MUCH for your helpā¦
I also need to go visit my mum todayā¦ sheās 86 and not well, so I better have some time with her todayā¦ BUT I WILL BE BACKā¦
THANK YOU SuzieQā¦

Hi eOS Guru @SuzieQ
We are not finished yet, but we HAVE made some good progress thanks to your last post. 
So my S9+ is NOT a brick thanks to you. I followed the above post (adjusted a few things which I will add below for others later) and am now back on eOS 0.14 O (Oreo) / A8.10 and I have eRecovery (not TWRP). SO GOOD to see that happy bouncing āeā againā¦ I know everyone thinks they have ābrickedā their phone but I was starting to really think I may not be able to recover. Honestly, thanks to you SuzieQ. So very grateful for your help!!
Okā¦ so thought it time to try to install A10 again, so put phone into Download mode, and ran Odinā¦ BUT it failed / stopped in the same place as before, at the section ārecoveryā of the flashing, with same error message: sw rev. check fail (bootloader) device
Soā¦ rather than mess it up again, I will stop and AWAIT your thoughts on how we might be able to get A10 on this phoneā¦
THOUGHT / COMMENT
I donāt know if this matters or is part of the problem, but in attempting all the above adb terminal commands, I first tried it on my Mac as you had given me links to D/L and install ADB for mac. It installed etc fine, BUT when I did the command to list the phone, it showed it started running adb and tcp/ip port number I think it was, so the output looked like it should EXCEPT it did NOT display the deviceā¦ it said hereās the list of devices but there were actually NO devices listed. Thinking it was a typical āmac terminalā thing where apple is always slightly changing terminal commands from the standard linux ones, I thought fine, I will just do it in my WIN 10. So I installed adb in WIN 10 etc, and the same thing happenedā¦ so I just ignored that, and thats when I did the .\abd and made it work
Very grateful
David
=====================
Comments re the previous post:
- Point 1. above was missing one stepā¦ āApply Updateā
So SHOULD BE: S9plus :: eRecovery > Advanced > Enable ADB > Apply Update > Choose from microSD - Point 2. above, I had to move the file āe-latest-star2lte.zipā into the same folder as the āplatform-toolsā so it could find the file to side-load.
ANDā¦ I dont know why but the terminal command would NOT work for me, until I put āa dot and backslashā in front of the adb command. I think it might be like a sudo addition in linux terminal. But it worked!!
.\adb sideload e-latest-star2lte.zip
=====================
Hello David,
I assume that you only mean it in the best sense, but I ask you not to ascribe superlatives Ć la eOS Guru to me. Yes, I have reached a level of knowledge with which I can master numerous problems around the /e/ OS installation. But I also know that there is much more I donāt know and that I make mistakes. After all, I have already turned three Samsung devices into electronic waste, even though Samsung devices are very robust smartphones in themselves.
/e/ OS 'Oāreo e-0.14 and eRecovery āQā e-0.13-q are not made for each other. We need to get Stock Android 10 with Stock Android Recovery installed on your S9+ for /e/ OS āQā and eRecovery āQā or TWRP Recovery to work properly.
Can you show me the āLOGā file āFAILā from Odin 3.14. as a screenshot according to my example below:
Since the firmware installation with Odin always fails at the same point, I can imagine that there is a defect in a partition of the memory.
If the S9+ was in my hands, I would now try to flash Stock Android 10 again - but with extended Odin options as shown.
The additional Nand Erase and Re-Partition will completely reset S9+ memory structure. Now click on the ā Start ā button to flash the firmware. During the flashing process, " NAND Erase " is displayed in the log field. Once the process is complete, your device will automatically reboot.
Odin 3.14.4 is Samsungās proprietary flash software. So these additional features are provided by Samsung to deeply impact the device. Itās not without risk, like any flash process, which Iāve personally already taken. Please make up your own mind und let uns know.

Good morning @SuzieQ
YES my comments were most respectfully offered, though I understand your comments.
I appreciate your understanding that its best to get the technically preferred position of A10 + eOS Q etcā¦ if we can achieve that, then I feel I have a phone that should last me years that should also be able to receive security updates etc. That is my objective as this will be my daily driver. I also understand the risk and am happy to be guided by you and will try the Extended Options in Odin when you say to. As you say, letās go
After your comments yesterday, I upgraded Odin to 3.14 also. I will now attempt A10 flash again and take photos as you requestedā¦
David
===========
EDIT: Adding photos as requested.
EDIT: Images removed
Hello David,
these photos are from today, so only taken now, right?
That means flashing with advanced Odin options didnāt fix the bug, right?
By the way: If you want, you can remove the pictures again,. Picture NĀ° 2 is very significant ā¦
Hiā¦
YES images from nowā¦
NOā¦ I did the standard flash (no advanced settings) so you could see it BEFORE I took the risk
Okā¦ my images have been removed.
I await your comments on my 2nd. imageā¦ and if I should do the extended flash, I am happy to. I DID NOT keep a copy of your image on that so now I am not sure what it was as far as what I should select in the extended flashā¦
I have saved the images.
How quickly can you download another stock android 10? device 14 binary 13 do not match.
I am happy to pay a few dollars and do it quickly like I did the other day from that samfrew.com websiteā¦
If I know exactly what I needā¦ i think it took 10 mins last time for 5 GB
Is it IMPORTANT to have the SIM in the phone when flashingā¦ ? as mine is NOT in the S9+ at this pointā¦ ?
hahaā¦ actually I am just trying to achieve my objective of a A10 / eOSQ
