Dude, I didn't come here to argue which you seem to want to do for whatever ridiculous reason. I don't know? Arguing about gear is stupid!!! So please, drop it. I'm merely asking if others are still having problems with shooting into the sun which even Fuji admits was a problem as have other shooters as well.
Edit:
Apparently I fail at reading comprehension. On the firmware update page for X-E2 it says for upgrades from 1.00 to 4.00 to execute SET-UP > RESET > SHOOTING MENU RESET and SET-UP RESET. After doing that everything works and I am back in business. Hope this can help someone else.
Original post:
I just upgraded to 4.00 from today on my X-E2 and have a similar issue. @perspektive says it worked fine for ~100 shots, but mine failed right away. I also Googled solutions saying to upgrade the firmware again, use different cards, reformat the cards before and after the upgrade, and different batteries, but also no luck.
The first time I turn on the camera after the firmware upgrade:
1. The display only appears in the EVF, which is weird since I had set it to display in the LCD.
2. Taking a photo results in the rear LED to blink orange and green indefinitely
3. The UI is completely unresponsive at this point. I can no longer take new photos, change settings, go into menu, or interact in any way with the camera since I believe it's waiting for a disk write.
4. The on/off switch is also unresponsive. No way to turn off the camera except for ejecting the battery :-(
Any subsequent attempts to use the camera slightly differs in step 2:
1. The display only appears in the EVF, regardless of if I changed it in the last run.
2. Taking a photo no longer causes the rear LED to blink or to turn on at all.
3. UI is unresponsive again.
4. On/off switch also unresponsive. Eject battery :-(
This is definitely reproducible across my Transcend and SanDisk Extreme Pro SD cards, and my Fuji and third-party batteries.
Ordered two on Adorama the evening it "went live" by compulsively "clicking-clicking-clicking" on the link until it went from "Unavailable" to "Available-Preorder".
The moment it did I raced through the checkout process in about thirty seconds and was done.
So I'm guessing I'm about as close to the top of the list as one can be.
An absolute childish approach, I know. But I lost my X-T1 to rain in May during travel, and have been struggling along on a single X-T10 since then.
(Why two? I will never travel or do a paid gig with one camera. I was a two camera Canon 5DIII shooter for many years. I abhor changing from lens to lens. I keep a wide or normal on one and a semi-long to long prime on the other. I have the advantage of a back-up if one camera fails. Re-enforced by having my X-T10 fail two weeks ago at work. Under warranty. Stuff happens. But I'm now shooting with a loaner from a friend.)
