    Hi,

    I used this great walk-through to flash my brand new Z2 Pro to latest stock ROM. I did the USB/QPST method and it worked great!

    One question : I am now stock with locked bootloader. If I decide to unlock bootloader and root, will it be possible to flash next rom releases using internal SDcard method without loosing apps and data?

    (I am aware unlocking will clear all, but that's a one off pain)


    Thanks

    If you take a look to the FAQ section as a proof. But as always no guaranty that it works without loosing data! Normally it never will wipe the data by using SD-Fuse method.

    Cheers

    Thanks.

    So if I understand right, this tutorial works only if starting with stock ROM.

    And it will work whether you are unlocked BL+Root or not. Right??

    Hi,

    could someone detail how to boot the phone to sdfuse with an unlocked bootloader ?
    I watched the video but it is hard to understand and on my side impossible to get to the SDfuse menu.

    Many thanks

    That's ok!

    I worked it out. The that when you reach the unlocked boot menu, you have to wait for the phone to boot. Then immediatly press the Vol- button and wait!

    PS: flashed using SDfuse method to restore system after various issues and it worked perfectly!
    I obviously lost custom recovery and root, but that's easy to bring back.
    All apps and data are still there!

    Thanks again for tutorials!

    Thanks. I got my phone today and flashed it no problem. They shipped with 2.0.48 multirom. The only issue I'm having is that I can't login to google app store for some reason. I'll have to play with this later. I'll probably side load google keyboard.

    Edit: After side loading google keyboard I was able to successfully login. It was saying "wrong password" with stock keyboard.

    Thank you for a great guide. I'll include what I received and what I did to flash the Stock ROM below:
    I got my Z2 Pro from efox-shop.com and they had applied a custom ROM on the device. These are some of the things that I noticed which were missing/different from Stock:

    Couldn't do any updates. The custom rom was 1.9. something
    UHealth was missing
    The Camera app had HFR and LFR, which i'm guessing means High Frame Rate (for high speed video recording) and Low Frame Rate (for slow motion). When selecting either of these settings, the video only recorded in high speed)
    Under Settings, Wallpaper and Font both went to Wallpaper!!

    To flash the Stock Rom I followed the 2nd post instructions, but I had trouble flashing the rom on a Windows 7 machine. However I followed the steps for Windows 10 machine and I successfully flashed the stock rom on my z2 pro... happy days :):) :).....

    .....and now on to my first problem, which I will post separately :(

    I received my ZZ2P today! What a machine!!! Top!:D

    I have a doubt. Now I'm going to install the rom stock, but how do I make a backup of the Custom Rom? I want to keep the Custom Rom of the seller for a day that needs to be replaced (ex. warranty). How do I do that?

    Hello, i followed this guide and the result was perfect. I wear the 2.3.044 version of the stock ROM. But before changing to the new stock ROM i had previously root my phone ... and now i went to do the OTA updates but the system mentions that because i have root this phone, the OTA won't come. Is there any possible way to unroot the phone back to normal ? Also i have the TWRP installed.

    EDIT : I downloaded the Root Checker to check if it is rooted but it says that's not... the truth is that i had rooted this phone. But with the new rom now the root gone but i believe some files are still inside the phone. What can i do to fix this ?
