[Samsung Galaxy Note 8 ROMs, Kernels, Recoveries, &] QSquared:
Yeah, the trouble has been that after flashing the firmware the Phone has been mostly ignoring any attempts to reach stock recovery and ending up in "UPLOAD MODE" instead, I have to press pow+ vdwn a good 20-30 seconds to get our of factory binary.

For a while i thought I could get into Recovery from fatcory but minute sof hoilding yeilds nothing there with pow + vup + bix.

I was able to get into recovery again afterward just a handful of times though and was trying a few things:

- looked at logs, and did a normal reboot

- wiped the cache

- got in a 3rd time immediately after cache wiping without trying, so did a pow off and pow on instead but no luck.

Now I literally just got in again, and I have been trying off and on for hours

Seems like the phone is SUPER finicky about letting me into Recovery totally unlike prior to flashing this bootloader in which case I was able to get in and out of recovery like clockwork.

So For anyone else who is STUCK on Factory Binary, here is what is "working": (Please note the LIBERAL use of air quotes around "Working" here. It's SUPER finicky)

FWIW, IME:

To get out of " Factotry Binary >>>> "you need to hold Pwr + VDwn for 20 to 30 seconds.​

The phone will go black and you have to keep holding or it will, stay off but the LED will be flashing (YMMV this was not consistent!)​

After 30 seconds to a minute you will get a quick tactile feedback "BUMP" -- You can let go now!​

This will boot you to a screen with two works = two values that only lasts for about 1 second, before changing to a new screen with a bunch of Phone Info and Samsung and Android on it​

You are Now Trapped on this screen in a different manner.​

If you leave this screen in place then after like 20 to 30 MINUTES you will end up in the Factory Binary >>>>> Screen again.​

This will boot you to a screen with two works = two values that only lasts for about 1 second, before changing to a new screen with a bunch of Phone Info and Samsung and Android on it​

If you press and Hold Pwr + VUP + BixBy or just Pwr + VUP​

You will end up in the "UPLOAD MODE" Screen! - some versions of this will include a crash depending on which buttons you were pressing.​

This screen is also a Dead end! AND can take anywhere from 10 seconds to a couple of minutes of pressing Pwr+ VDown, while Pwr + VUP / Pwr + VUP + Bix will just get you back into this screen again, and more likely to have the longer wait scenario - although you get to that new copy of the screen much more quickly, so that... not really much of anything really.​

SO What to do?

Get back to the Android/Samsung Screen I mentioned above, THEN:

Hit Pwr + VDown until screen goes black.

IMMEDIATELY Let go of all buttons, then qucikly change ot pressing Pwr + VUP + Bix!

As soon as you feel the small "BUMP" of haptic feedback, let go and wait, in 20 ish seconds the Red screen SHOULD (But MAY Not) flash by, Upon seeing thast screen flash up Press Volume Up or Vol Up + Pwr (YMMV) AND LET GO AFTER ONLY A MOMENT

IF you timed it just right you will go right int othe Recovery mode after BREIFLY seeing the INstalling screen \flash up (it's maybe a second at most that it show).

HOORAY! Just got that to happen myself ! Going to "Wipe Data Fatcory Reset" and leave the phone while I go out ot pick u the kids.

Wish me luck! :)
