Guys, finally I've joined the club.

Got my K3 Note to replace my trusty old Z10. I love BB10 OS but due to some circumstances I just had to be apart and move on with life.

I just wanted a decent phone with good camera capability and the K3 Note didn't let me down.

Now my phone is running stock Android 6.0 (I guess the dealer pre-flashed it for me), stock Lenovo launcher, Blackberry keyboard, and that's it. Not planning on rooting anytime soon.

OK not sure what did I do wrong here.

My K3 Note details....
- Unrooted (confirmed using Root Checker)
- Currently running custom ROM K50-t5_S422_160315_ROW

I want to flash to stock ROM K50a40_S427_160518_ROW. I already installed Lenovo USB driver 1.1.16, hoping that I could get OTA updates in the future.

My problem is that it seems that SP Flash Tool won't 'download' or 'flash' the rom to my phone. Nothing happens. I'm pretty sure I followed the correct instruction, but I could miss something.

I'm using Win10 64-bit btw....if that helps

at last I am able to flash using SP Tool

I don't know why, but I had to play trick with the battery.

TURN OFF PHONE --> PULL OUT BATT --> PRESS DOWNLOAD (sp tool) --> RECONNECT USB TO PHONE --> INSERT BATT (only then the sp tool detects my phone and flashing starts)

1. Any problem using SD cards larger than 32GB after flashin to Marshmallow? I might be getting 32GB or 64GB but haven't decided whether to use it as internal or external storage. 64GB is probably the max I'd get. Any larger I'll just backup through OTG usb or something.

2. Between Sandisk Ultra and Sandisk Extreme is there a significant difference in performance when used as internal storage?

There are many cheap and expensive fake Sandisks, they corrupt easily. But original ones are easy to find as well, just make sure buying from reputable shops.

But I also open to other brand recommendation.

using stock global s433 now .... i think the wifi is a bit slow
anyone experience the same?

1st. download app called BlackBerry Manager. You can get it HERE (I don't think it's in the Play Store).
Then from within the BlackBerry Manager you can download the BB keyboard, as well as other BB apps like the Hub, calendar, contact, etc.)

the hub is more like the one in Priv or DTEK50 i think
still cannot beat the efficiency of BB10's own hub
