Windows 10 Mobile Build 16212 Upgrade Guide (Phone Updater).

Very important note to acknowledge: This is still PROOF OF CONCEPT, You will encounter some bugs/issues/lack of features! this is not a Daily Driver build!

I will not be responsible for any damage done to devices, as with all test builds there is a risk.

The 16212 update cabs are hosted by me on Dropbox/Mega, if you have issues with dead links let me know so I can fix the links and updater lists

Please read Known Issues (WIP) before continuing.

Tools needed:

Notes:

  • A Hard reset is required to make Microsoft Edge work, but breaks Action Center and Developer Mode being active
  • Upgrading to 16212 with CShell XAML will cause any applications previously installed to not show on the Start menu. Only 'New' apps show
  • Microsoft Store does NOT work, we've tried several versions and no joy
  • Developer Mode cannot be toggled through settings
  • Text artifacts will occur on non en-US locale
  • No Silverlight (XAP) support
  • Use Device Portal to install an app like Interop, W10M Group App or UWP Package Installer to make installing apps easier
  • There is no Notification Gesture. tap the Notification bar to open.
  • If you are using Windows 8/8.1 and are NOT using the Flight Enabler Script you need this bcdedit.exe from Windows 10
  • Root Access is not yet supported
  • DO NOT UNLOCK BOOTLOADER ONCE UPGRADED TO 16212, YOU WILL GET BSOD.

Start: Finding out what Guide to follow

Use This RCS Checker Script to tell you if RCS (Rich Communication Services) Feature Pack is installed. There is a possibility that some devices will suffer an IPOverUSB bug or something that prevents device logs being fetched

  • Plug device in to PC
  • Launch 'RCS_Checker.bat' as Administrator
  • Wait for result to print on-screen

The reason RCS Feature Pack causes issues, is because Microsoft.MS_RCS_FEATURE_PACK.MainOS.cab is merged into Microsoft.mobilecore.prod.mainod.cab in 10.0.16212 so conflicts will happen the update is processing files to replace.

RCS Feature Devices:

Make sure to enable Advanced Settings

  • Flash original FFU (Update to 10586.107 after, if you are on WP8.1)
  • Interop Unlock your device and enable System access over MTP USB or deploy Storage Explorer XAP if you cannot use MTP
  • Navigate to C:\EFIESP\Windows\System32\Boot on the device and copy/replace resetphone.efi with the Production Dev Menu , backing up the original file.
  • Shut Down the Device, when the manufacturer logo is shown, keep pressing Volume - button until Developer menu appears, then use Power button to select USB Mass Storage Mode
  • Extract and run as Administrator Flight Signing Enabler Script
  • Set Date and Time to 4th August 2016
  • Update to 14393.16212 (This is just 14393.1066 but Including RCS Feature Removal Cab)
  • After Updating to set date to 2nd June 2017. Enable Developer Mode BEFORE updating to allow installing Apps after.
  • Open Phone Updater and connect you Phone
  • Then choose to upgrade to build 16212.1000
  • Wait for packages to be downloaded and send to your phone
  • Continue and the Update should be pushed to the device and install.

Suggested Post-Install Actions/Notes

  • Interop Unlock is recommended, Interop Tools Beta v1.9 works atm
  • If the Production Developer Menu didn't persist after Update, Interop Unlock and re-copy it as above.
  • If you need to enable Developer Mode and have access to Mass Storage Mode, Use the 16212_Patches Script to manually enable Developer Mode
  • Use Device Portal over USB/Local Wifi to Install Interop Tools or W10M Group App to allow App Installation on device. Windows App Installer doesn't show/work.
  • After connecting to the Internet, some Apps will still update/install. This can take a while so let the phone complete app installation for better results.

Errors:

If you receive error Preparing the update in the phone, send your "ImgUpd*.log" files:

  • Open iutool's folder in Admin Command Prompt

  • getdulogs -o .\DevLogs.cab && .\DevLogs.cab

  • Explorer will open the log cab, extract ImgUpd*.log(s), then send here.

  • If you boot to a black screen (bootloop) you may have left the Platform Manifests, restore with WPInternals.

Update Errors

For a full list of iutool errors, go here

Shell Cabs:

We can choose from 3 Packages: CShell XAML, CShell Splash, and Splash Shell. It's down to you what you want, just don't apply all 3 shells!

  • Splash Shell - This is what everyone already uses, this is the 'normal'/'default' Start menu for W10M 15254 and below

  • CShell XAML - This is the CShell based on XAML start, it includes a new Action Center, Start Menu interactions etc.

  • CShell Splash - This is based on Splash Shell but includes some small visual differences from CShell XAML, just no extra features.
