Blackscreen after MI logo - Xiaomi Mi 8 Questions & Answers

Hi everyone,
Around two weeks ago my phone fell to the ground. The panel shattered and only the top bar kept displaying (the one with the time). The touch input also stop working.
I had several alarms every day and the only way for me to stop them was to reset the phone by keeping the power button pressed. After a couple of days doing this, the top bar also stopped displaying.
Today I got a replacement screen, I connected it to the phone to test it, but when I turn the phone on, it displays the Mi logo and then the screen just goes black (see video youtu.be/_RwtKpJGjRU), this also happens while the phone is connected to the charger.
When I "volume up + power" same happens.
When I "volume down + power" no Mi logo appears, the screen remains black the hole time.
Find my phone on the Xiaomi Cloud does not work.
The phone is connected to WiFi and I can ping its IP address.
When I connect the phone to my laptop with the usb cable, the laptop recognizes it, but Mi PC Suite does not connect (I guess this happens because I cannot select the type of connection on the screen).
I have no clue how to solve this problem.
Anyone has any idea?

Diamond does not Power On

Hi i have a few issues on my diamond. I hope you guys could help..
1st issue: lately my diamond keeps on resetting by itself.
2nd issue: later I've learned that when I record my voice using the software within the ROM, I don't hear anything but when I record my voice using my htc headset/earphones there is a sound.
What I did was:
This day I've flashed a new rom (Energy Rom) into my Diamond. It works ok then I flashed the Radio (Radio_1.13.25.24). I was able to use my diamond for a few hours.
Now..
3rd issue: My diamond is not powering on..
What i did before this happened was...
I pressed and hold the power button for about a few seconds so the ShutXP would pop up and I could soft reset my diamond.Before I clicked the soft reset button, I was checking out all the functions of it. then i clicked, a little icon,which is the Setup Timer Action. Here's the setup:
Action: Turn Off Pocket PC
In: (i don't exactly have seen the time indicated)
As curious as i am, I Clicked the Set Action button. It did shut my diamond off. Then I tried turning it on, but all it was doing was vibrate and the screen was black. At first I was hearing the start up sound a few times but later it didn't hear it anymore. I plugged in the charger but there's no white light on the circle button which used to have a light on the borders of the circle button when plugged in the usb cable. I tried pressing the power button plus the Volume down so the bootloader would appear but it did not. What shall I do?
Are you sure that the screen working because the phone vibrate and play the startup sound so if think its the screen that have som serious problem !!
HELP
I also flashed a new rom (Energy Rom) into my Diamond before.
It cannot run window mobile6.5.........how can I do???
I cannot connect to PC .......
I recently also had a similiar problem, after attempting a flash of the Rom, the ROM update stopped halfway through and reported that it had lost connection to the device....
The whole phone would not vibrate/power on, nothing - no glowing ring around the middle button to indicate it charging at all.
I had to return to the repair centre and somehow they didn't notice that I had modified the firmware and replaced the whole phone for free citing a hardware issue ...
Doesnt sound good if you cannot hard reset the device

Powering X1i through USB -- any hacks to do the following...

Hi all,
I frequently charge my X1i through USB. There are 2 problems with this method, however.
1) The device goes into USB drive mode, disabling my SD card apps (I keep them on SD card AT ALL TIMES due to frequent backups/restores)
2) Screen does not turn off! while connected to computer! The screen only dims, but does not turn off.
WITHOUT resorting to a) plugging into wall outlet b) connecting to Activesync, is there any to fix these behaviors?
Thanks!
just let it go into activesync mode, that way you can still access your files on your phone and micro sd card from both your pc and phone. And if you dont like the screen not turning off, they just change the settings or just press the power button, to shut off the display.
I know about the power setting, but when your computer is connected to the computer via USB, it refuses to turn off the screen (only dims it)
what? one simple button press and the screen is off. the device is still visible to the pc. I do it all the time - r3a generic uk rom.
in power options u can set after what time it disables screen... default is never

Weird. When I'm connected to Pc, it dims the screen, it does not shut it off. Also, it does NOT auto-shut of screen after the 2 minutes specific in the Power options
You can also use "safely remove devices" to disconnect the data connection from the phone, it'll still charge.
There's nothing we can do AUTO. But like said before, a simple pression on the power button will do it, or you can use My Mobiler and press F11 on your PC.

Yep, I've had 5 different WinMo devices since '05 and they all worked as expected except the X1. I like to use it as an MP3 player at night, Pocket Player has a sleep timer built in so I just like to leave it running as I drift off most nights. But if I do anything, change the volume, rewind, anything at all the screen comes back on and stays on until I hit some other button to turn it back off. All my other devices obeyed the settings you set in the Power tab, but not the X1...
I'd very much like the screen to auto-off if I tell it to while on USB power. It's not only wasting power, but it wakes me up and gets me fumbling for the tiny power button at 2 in the morning. Any fix would be greatly appreciated.
Thanks,
Peter
I bumped up thread: http://forum.xda-developers.com/showthread.php?t=561832 Since it has a better title and shows the exact same unresolved issue...
Reg Fix
Adding this potential fix here as well so anyone subscribed to this thread sees it.
Ok, I think I have a fix for this. I googled around some more and found that this might be an HTC problem more than an SE one. There were various registry keys people suggested to try to fix the 'backlight problem' - which may or may not be related. None of those suggestions seemed to work, but I kept changing keys myself and eventually found this seemed to do the trick.
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Power\Timeouts\ACUserIdle: 120
I confirmed that changing this value affects the amount of time before my X1's screen turns off - but my MP3s still play with the screen off and my phone wakes on receipt of a new call. This value is the # of seconds before the screen turns itself off (in this case 2 minutes). You do need to soft reset for the change to take effect.
This doesn't seem to be posted anywhere else that I've found doing this to fix this issue issue - I changed a few other registry keys as well that might be enabling this fix. So anyone with this problem, please do give this a try and if it doesn't work I'll post the other keys I changed as well - and if it does then post to say so and we're good

Update: I tested it also while hooked up to the computer and it does work with the phone accessible through active sync with the screen off and the battery charging (faster now that it isn't competing with the screen for power, except for the 2 minutes before it times out). If I want to use it I just click a button and the screen stays on till I leave it alone for 2 mins and it remains off. Get a call or a message and the screen goes on for 2 minutes and then off - Exact same behaviour on AC and USB - exactly the behaviour I wanted .

Glass wont go into fastboot mode.

Hi, just got a google glass xe-c a few days ago. It had a problem with wifi not connecting, trying to activate it using qr code gave an error "cannot connect to network" I had to activate it using mobile data in tether mode. Wifi settings card is always stuck on "turning on" everything else worked fine adb , fastboot hardware buttons etc.
I restored the factory image "xe23" from the official website but no change in wifi status. Today I got the bright idea to "downgrade" it.
just to have a look at older firmware and i thought maybe it would help with my wifi issue so i downloaded and flashed "xe10"
turns out it did not have the "activate using mobile data " feature and only way to activate it is using wifi, so i am stuck at activation screen. I tried pressing camera + power buttons to go into fastboot mode and it wont.
If i disconnect the usb cable , power off the device then hold down camera button and press power button, power led turns on , I release the power button while still holding camera button after a few seconds led is supposed to flash instead it just turns off and after that if i connect the usb cable nothing happens.
I also tried another approach, If i keep the usb cable to the pc, then power down and press the camera +power buttons , led again turns on , pc dectects the glass in fastboot but only for a second , again led turns off and thats it.

Wifi only works after restarting the phone

I have a strange issue where the wifi will stop working until I restart my phone, this happens everyday seemingly at random.
No other devices in the household have any issues connecting to the wifi and at the time I've lost connection i've tested their internet access and it's working fine.
Is this a known issue?

Mine, this morning for the first time, wouldn't connect - it just sat there with the icon light blue instead of dark blue, like it was still trying. Only mine also started getting worse, when I tried to cancel WiFi, it wouldn't - I tried to open "Settings" and the screen took forever to open, every subsequent screen took even longer to open until finally I had a white screen with an Android Header and Footer but otherwise blank page. I waited about 2 minutes, tried to hit the back arrow - nothing! Finally, I hit the power button and selected "Restart" - now it gets worse! The screen goes black, the phone's LED starts alternating slowly from green to blue and continues this way on my kitchen counter for 10 minutes. Never reboots!!! I finally used the "Vol Up>Bixby>Power Button" combo and it shut off. I hit the power button to turn it back on... absolutely NOTHING - DEAD! Plugged it in - didn't recognize that it was being charged! Crap... what did I do! Stop, think... O.K., one more try "Vol Down>Bixby>Power Button" combo - up comes the "Software Load" screen - I hit "vol down" to cancel and it rebooted - back to normal! No IDEA what the hell that was all about but thought you'd feel better knowing it COULD BE WORSE!!!
Well thanks. I'm glad yours is sorted.:laugh:

Rog Phone 2 screen froze and 1 long beep then die

Was on videocall when the screen suddenly froze with 1 long beep(about 5-10 sec) then screen black.
Can't turn on, can't charge, tried all the button combinations(holding power button, voldown+power, volup+power, volup+down+power).
But when I connect to my laptop using the side port I can see it in device manager and miflash, but it gives me "cannot receive hello packet",
