What some people have been asking is about this file in samsung.firmware.science that upgrades you from BQK5 to BQL1 and has a bootloader of S1 instead of U1 or U2. L1 is newer than K5, since L comes after K

[Samsung Galaxy S8+ Guides, News, & Discussion] rizzo269:
All of these oreo version options are awesome to have. I'm going nuts because my laptop doesn't work with Odin (something to do with USB 3.0) and my wife is out of town and took hers which is what I usually use. Tomorrow I just might have to go in search of a computer and load up KQKQ.

Great support in the thread even though the versions can get complicated.

I'm going to go out and say I just did it with USB 3.0 on my desktop
[Samsung Galaxy S8+ Guides, News, & Discussion] rizzo269:
I know. My wife's is 3.0 too and it works. Mine gives me the cant open serial port message and errors out. If I have it in my docking station at work and plug my phone into the dock it works but not with the USB on the laptop itself.
[Samsung Galaxy S8+ Guides, News, & Discussion] tailgunner9:
By time flash back to BQK5 then Flash ZQKQ they will be out with another Beta and have to do it all AGAIN.... Would think the file would just Update the previous Beta version.
[Samsung Galaxy S8+ Guides, News, & Discussion] mycomputerisjunk:
The more I read the more the confusion sets in. I am on a Verizon s8, SM-G950U with AQK3 firmware. So, do I just flash AQGL then flash U1AQGL-to-U1ZQJJ? Which is beta2. Um, then what if I want to get to beta 4? Flash back to AQGL then find beta4?

Are firmware for 955 and 950 interchangeable?
[Samsung Galaxy S8+ Guides, News, & Discussion] xdanilva:
950 and 955 aren't interchangeable. I also need to ask somebody for the g950 files rn.

Device manager is good to go. Never heard of USB port protection but I'll take a look today. It's a very strange one because I can transfer files to and from the phone with no issue. It's only Odin communication.

Sorry for the silly question, but how do I update to the latest nougat beta? I have a 955U1 on T-Mobile at the moment. I'm on the latest nougat OTA. Thanks.

Do I just flash the latest Oreo update.zip using adb sideload?
[Samsung Galaxy S8+ Guides, News, & Discussion] crixley:
Not to be rude but this has been answered on nearly every page.

Long story short:

Put the K5 to ZQKQ Ota zip on SD card

Odin BQK5, flashing home csc instead of csc if you want to keep your data

Boot immediately into Android recovery

Flash the K5 to ZQKQ Ota zip

Voila

[Samsung Galaxy S8+ Guides, News, & Discussion] cam30era:
I have just seen a couple of threads on the XM forum, from users who did a SIM swap to an unlocked non-XM phone. After about 2 months, VoLTE option doesn't work anymore. No statement from XM about this, but it looks like XM eventually realizes that a "foreign" IMEI is on their network and disables VoLTE.

You can try returning the SIM to your XM phone and see what happens. If you do call them, don't mention the fact that you were using a non XM device.....

[Samsung Galaxy S8+ Guides, News, & Discussion] Dudash:
I never said it would start showing "Certified". The device will never show that until the official Oreo release.

As far as app updates, you'll still get normal app updates using the 440 variant of Google Play Services but the device certification is how Google Play knows whether or not your device is authorized to use Google Play Services and since it isn't, Google Play Services itself won't update. I'm kind of surprised they didn't include a 940 variant in the update itself.

I know that it is updating from bootloader 2 to a bootloader 1 version of Oreo but since the update zip exists, could it be possible that this could downgrade your bootloader?
[Samsung Galaxy S8+ Guides, News, & Discussion] Josephigloe:
You can't go from bootloader 2 down to bootloader 1 you'll mess up your device this was tried before and ended up bricking his phone.
[Samsung Galaxy S8+ Guides, News, & Discussion] Dudash:
I know you cant via odin/twrp/etc but I wondered if this method would work since this is via an official update that you would flash in official recovery. Unless that's what you meant. If that's the case, nevermind.

That's not what I'm saying - And you can NOT Flash S8 Firmware on the S8+ and vice versa - I think that the issue is both devices appear to be supported for development on the same Thread - But you have to filter out what is not relevant for your specific device.. I know that it gets confusing when people with different devices are posting on the same Thread... And to me (fwiw) it would probably be better if the S8 and the S8+ discussions were confined to separate Threads completely... Just my 2 cents ?
