[Nokia 8.3 5G (8V 5G UW) Guides, News, & Discussion] hikari_calyx:
As I mentioned before, unlocking the bootloader will fix this issue.

But if you don't want to unlock the bootloader, then this guide is for you.

DO NOT USE THIS METHOD IF JUNE 2023 OR NEWER UPDATE RELEASES IN FUTURE!

YOU SHOULD NOT IGNORE, REVERSE, SKIP ANY OF THE STEPS!

We assume you know how to use ADB/Fastboot commands.

Before you proceed, make sure you have your phone's battery charged as much as possible, or the bootloader will not allow you write any partitions.

1. Download this package and extract:

Non-Chinese users: https://www.androidfilehost.com/?fid=10620683726822058340

Chinese users can download from here:

SHA256: 72425ebdf249f523c81646786eb92d57229e9164ad25be2ef2d920eb7176fcd3

You should keep at least 10,030MB (10GB approx) empty space.

2. Open FastbootDriver folder and open DPInst64.exe (or DPInst32.exe if you're using 32-bit Windows) to install correct Fastboot driver. Once Fastboot driver installed, open RegistryFix.reg to prevent fastboot mode become unstable.

3. Sideload Android 10 Full OTA Package Under Recovery mode. Enter Recovery Mode by using either of these 2 methods.

- Execute these 2 commands:

fastboot reboot-fastboot
fastboot reboot-recovery

Then this phone will boot right into Recovery menu.

- At Fastboot screen, use Volume key to select Recovery mode, then power key to confirm.

When you see Android robot lying, press Volume Up key while holding power key to get Recovery menu.

We recommend users to use method 1 as many people don't know how to press such combination key.

4. Download this Android 10 Full OTA package:

https://android.googleapis.com/packages/ota-api/package/627142c637bf373410e6b8911aeb9b2e65bd5969.zip

or from here:

https://www.androidfilehost.com/?fid=10620683726822057898

Chinese users who don't have access to Google server can download from here:

https://api.hikaricalyx.com/FileDownload/CTWorks?id=f427f5862b7749

SHA256: ba940f216f8d69de988005a6c61ba03073a5b0aacb0789005db5f2f2befe1a02

Please re-download this package if SHA256 is incorrect.

5. Use volume key to select "Apply update from ADB", then power key to confirm.

6. Execute this command to sideload Android 10 Full OTA to your phone:

adb sideload /path/to/627142c637bf373410e6b8911aeb9b2e65bd5969.zip

You may see downgrade not allowed message on screen, but it will be installed anyway. Wait for the procedure completes.

If the procedure halted at 94% and it says "adb: failed to read command: No error", it's expected.

7. Use volume key to select "Reboot to bootloader", power key to confirm.

8A. To Windows users, double click "0_OpenMeToInstall.cmd", and wait for the procedure completes. We only guarantee it will work on Windows 10 and 11.

DO NOT RUN IT WITH ADMINISTRATOR PRIVILEGES!

-

8B. To non-Windows users or you prefer to flash the package manually, execute these commands. It's absolutely discouraged to use outdated Fastboot binary (e.g. Minimal ADB and Fastboot).
