How to flash an initial WM10 rom (3.12.2015)
** first step if you are coming from android **
Tutorial:
Mi 4 LTE (4G) Windows 10 Flashing Steps and FAQs - Read before Flashing
Windows 10 Flashing tool Miflash-20150601 for Mi 4 LTE (4G)
flash method working .. tested

*** next to problems with installing mentioned in tutorial .. I need to say that custom rom in device can be problem too. For example, I had installed DU rom with merged partitions 1.2GB. First I had to do re-partition, then I returned official MIUI rom through MiFlash tool, and only then flash WM10.
*** Not enough storage is available to process this command (0x80070008: Max buffer sector is 256)
Try flashing with 64 bit PC with win 7 or win 8 installed on it, AS 32 bit PC will most likely give the syntax error/ Buffer error.

1.download MiFlash tool version 2015060 (if you have not already) and install it (it is desirable not to change the installation path). - link
detailed instructions
2. Get Firmware Download - link
extract firmware download to folder (I do it on the desktop).
3. Turn off the phone and then holding down the volume down + power button to enter to 9008 recovery mode. Wait for it to load, and then will turn off the screen, after then connect phone to the computer. Click "Refresh" in MiFlas tool to connect Mi4 LTE.


Now, BROWSE button is used to provide the path to the folder where the files are stored.

maybe you will have this error.
1. Try download firmware package again
2. Set MiFlash tools path to default (c: / program files / Xiaomi - Do not change folder names).
3. Restart the computer
Second method .. not tested
If you have earlier build than .63 (ie .29 or .36) Try this ...
Open the "Windows Insider " application. Into "Windows Insider " application select "Get a preview version". Click to select "Insider Fast", then click on the bottom of the screen "->" Go to the next .In the Confirm page, select "Accept" eventually go to "Finish" to complete the confirmation page.
Now system can automatically find updates regularly, or you can go to the "Settings"> "Updating and security"> "Phone update"> find and install updated manually .
