    Description

    This guide will show you how to impersonate another device and get WP 8.1 Update 2 (OS version 8.10.15137.148)



    Warning:

    1) Changes made to your phone are not permanent and can be restored using Lumia Software Recovery Tool or Windows Phone Recovery Tool

    2) I would not be taking responsibility if you accidentally brick your phone so please ask questions before proceeding



    Software Requirements:

    1) **Any Nokia Lumia running OS version 8.10.14219 or higher. If you are on a lower version please check for updates from your carrier/Microsoft or update using Preview for Developers

    2) Start with a clean software, i.e. reset your phone before proceeding (make sure Preview for Developers is not installed)

    3) Files Needed (download link)
    ** I do not own these files. They were linked from this thread **

    a) SDK 8.1 Lite.zip (*** install this after download ***)
    b) CustomPFD_0003.xap
    c) CustomWPSystem_0500.xap




    Hardware Requirements:

    1) ** Nokia Lumia with SD card capability

    2) microSD card

    3) USB cable




    Process: Part 1 - Preparation

    1) Hard reset phone using hardware key combination (Reference)

    2) Go through setup process, update all system and preloaded apps

    3) Storage Sense >> phone >> apps+games >> select all >> uninstall all apps

    4) Storage Sense >> Store new apps on my "phone"

    5) Connect phone to PC using USB

    6) PC >> Start Menu >> Programs >> Windows Phone Developer Registration >> Register >> Enter MS Account >> Done >> Close

    7) PC >> Start Menu >> Programs >> Windows Phone Application Deployment 8.1 >> Target = Device; App = "pathoffile\CustomWPSystem_0500.xap" >> Open >> Deploy >> Deploying File >> App deployment complete. >> Close

    8) Verify if CustomWPSystem shows up in app list

    9) PC >> Explorer >> My Computer >> Select Phone >> SD Card >> Documents >> Move CustomPFD_0003.xap here >> Done

    9) Storage Sense >> Store new apps on my "SD Card" >> Done

    10) Store >> Download Preview for Developers >> Let it install >> Don't open after install >> Pin to Start >> Done

    11) Open CustomWPSystem >> Click on red bar "SD Card permissions" >> Select "sd card" >> Press "done" (check mark below) >> red bar turns green

    12) Scroll down under "Modding selected app", select "Select the XAP" >> Phone >> sd card >> Documents >> Select "CustomPFD_0003.xap" >> Apply XAP >> Wait till you see popup "Operation completed!...." >> Done >> Close app



    Process: Part 2 - Registry Edits

    1) Open previously pinned Preview for Developers app >> HKLM >> SYSTEM >> Platform >> DeviceTargetInfo

    2) Edit Registry:
    ** Note down the registry keys before editing them. To avoid resetting, revert back to default registry entries and skip 4) **


    PhoneMobileOperatorName >> 000-88 >> Write
    PhoneManufacturerModelName >> WinWin >> Write
    PhoneManufacturer >> HIGHSCREEN >> Write

    ** Registry edits are restored to default with hard reset **

    3) Settings >> phone update >> check for updates >> Install Updates >> Done

    4) Reset after updates are installed >> Start fresh

    Is it necessary to hard reset before registry hack, I mean can't I directly hack the registry, then update my phone and then hard reset.. ??

    Thanks panka981 , I could install update 2 on my Lumia 520.
    I have an issue though. My volume buttons are not working. How do I reset my phone to get back the proper model name ?
    Does setting->about-> reset my phone work ?

    You can begin without hard resetting to save time

    Please read carefully, this is not via Windows Insider. Your phone impersonates another phone's model number to receive the official update.

    Have you faced any problem yet ??
    I've been using it for more than a couple of weeks now. No issues anywhere

    finally got some time to try this. I hope I can change this post soon. For now it has been sitting at "Checking for updates...." at step 3 of Part 2 for 45min. Not sure what to make of it yet....

    edit 1: ok, after more than 45min I am at least getting a "problems connecting to server" error. Maybe I should reboot and try again.

    edit 2: after reboot, registry settings are still set to impersonate a different phone, but it keeps sitting at "Checking for updates..." again for now.

    in the back of my mind I think that ATT is secretly following this thread and locked my phone remotely - ha

    edit 3: finally after some long waiting I am getting an update and it is installing.

    Nope no problems as of yet. Pretty happy with it. Great now.

    Far more responsive. Super fast switching between apps, great to have the settings area in sections much easier and quicker to find things, the keyboard is super fast too and autocorrect is really good too vast improvement, the phone itself looks brighter (don't ask me why). Lumia camera pictures are really clear dare I say much better.

    Took me a while to check for updates after I put in the registry values, I think it took about 50 mins to find it then once it was found it was plain sailing from there.

    Yes do I thought I wasn't getting it but I just waited and waited and the little message popped up update available. Can I ask do you close the PFD app and then look for update or do you have it open, tap the start (middle) button then look for updates?
    I left the app open, pressed start, swiped to settings and looked that way. I kept my phone plugged into the wall if your battery level falls below a certain level it wont find updates.

    I tried both with PfD open and PfD closed. Since the registry settings stick after reboot I do not believe it matters.

    I am getting the update now, at least I think it is the right update ;)

    edit 1: oh well, "the update downloaded but couldn't be installed" with an error code (8018830f).
    PS: searching for the error on Bing brings up a number of sites where people post similar issues going back 2 years ago with other OS updates. Some say memory, some say not known...Some say to use Software Recovery tool and then it worked, while a hard reset did not.

    and here the official word on that error from MS:
    http://www.microsoft.com/en-ph/mobile/support/faq/?action=singleTopic&topic=FA143712
    Interestingly, it describes this for the Denim update scenario...

    According to the posts above it seems that a simple hard reset may not work because the image may not be 100% ok (this is my uneducated guess). Folks had better luck with the software recovery tool.

    edit 2: starting over one more time. hard reset and sdcard format
    No dice, same error at about the same percentage in installation. I am starting to believe it is the image on the phone that creates a recovery that does not work with the udpate. I am using the Windows Recocery Tool next to create a new image and start over from there.

    last edit: Even after using WP recovery tool - nada, I give up, same error at same percentage of installation. I don't like my phone anymore.....

    At least I know I can install W10 preview

    Are you using the right program for flashing the rom to your phone? The way I did it I flashed a non country variant of my lumia (made the patch think its another Lumia) then proceeded with the Reg edit and such.
    You need NaviFirm+, Windows phone image designer (both pc programs) and you also need the image designer driver.
    NaviFirm+ to download the ROM.
    Windows phone image designer to apply the flash.
    The driver for the usb to become its own self contained boot loader.

    Another thing I've noticed the sound from my speaker on my phone is much better, far clearer and I have to say you can hear the bass alot better even though my phone don't support equalizers due to hardware limits update 2 however smashes that!! Super happy!!!

    Your guide was primarily geared towards Samsung users. This guide here is a custom guide for those with Lumia phones. Your guide was good though. 😊
