Can downgrade? yes or no?

Hello is it possible to downgrade this new firmware release?
I have already tried all other stock ROMS and ODIN FAILED all time.
I just want to confirm if its possible to downgrade, if yes, then how to go back to 5 1 1.
Thank you for reading

I think it is better to prevent user to downgrade their Phones. As you know, since Android 5.1.1 released, Google replace the Samsung Reactivation Lock with their Factory Reset Protection. But in the lower versions of the android, there is many way to bypass this protection on Samsung Devices. Samsung fixed it on their security patches. Just imagine that if user can downgrade their phone to any version of android, when a thief steals the phone, they can easily to bypass it and make the phone become theirs.

Thank you for replying but I am still clueless if I can downgrade that specific android version I showed in screenshot above.

no one?

Have you tried TEKHD's stock-rooted 5.1.1?

You cannot downgrade... Once bootloader is upgraded there is no way back. You can try but highly you'll end with bricked device ... Also if you try custom roms they wont boot due to mismatch bootloader and recovery. Maybe if you search google you will find a way to do it but if i was you i would not take the risk

Can I do OTA upgrade to Marshmallow 6.0 on SO-02G running D5803 UK Lollipop?

I just got a used Sony Xperia Z3C from Japan (Docomo SO-02G). I tried to convert it into D5803 with UK customized firmware by following instruction from an old YouTube video but I failed and bricked the device. Luckily, someone else repeated the procedure again and successfully installed the same firmware in the handset. It’s running okay with exception to few bugs but there’s a problem.

I directly downloaded the file from an old tutorial and it was 5.1.1 Lollipop where Z3C can be upgraded to 6.0 Marshmallow. Now I’m afraid if I attempt an OTA upgrade, it’ll either end up installing SO-02G (Docomo Japan) latest OS or brick the device once again. Some people say that I should go for update and it will only upgrade it to Marshmallow for D5803 since it’s already running Lollipop for the same version. Others say I’ll have to find a latest firmware for D5803 and start the procedure all over again.
If I must install another firmware, which one should I choose? Is Global Generic version a better option? I’m from Pakistan where Z3C was never officially launched, so I can take advantage of not having country/region specific apps which are normally loaded in non-global models. Look at the size; 1.05GB vs. 1.59 GB.
And last but not least, how do I know the firmware file I create using Sony FlashTool is of the latest Android Marshmallow 6.0 for Z3C?
I’d prefer a stable stock OS as I am a normal phone user, not a developer, hacker or a gamer. I think after upgrading to Marshmallow, there won’t be any major system update.

I guess images gone missing because system doesn't allow new members to include urls :/

Moving Forward: Updating Tencent Edition - 1910.35-0

Hi, bought this tencent edition flashed to global rom off-market. Unfortunately, it doesnt get OTA updates so I'm currently stuck on android 9. I have read some guides on how to convert CN to WW, china to global, tencent to global, etc., but I'm afraid I might end up bricking my phone if I try to tinker with my phone without any background. Any help on how to proceed would be great. Just want a way to update to android 10, getting OTA updates would be a bonus. Here's the system info:

Go through all steps

I currently have a tencent edition ROG Phone 2. I changed it to the global rom and changed the fingerprint to WW. The step by step instructions are pretty easy to follow, I think. I haven't had a problem with it since. I am current using a global Android 10.

Same here bought the tencent set and convert to global rom. Just follow the instruction, watch the video at YouTube, read the whole procedure over and over again, proceed only when you are confident enough

Question Netflix is not compatible with Oneplus 10 Pro

Hello
I was surprised to get this message when installing Netflix [ Your device is not compatible with this version ] , the Netflix application is not available in my playstore Google .
I don't know why the oneplus doesn't have its certification from Google.
I contacted Netflix and was told that the Oneplus 10 Pro is not listed in database
My Oneplus has the latest version International NE2215_11.A.13 OTA
Netflix is still not available on the Google Playstore ( look picture)
I have installed the manual version
Netflix
8.27.0 build 5 40228
When I launch the application I get this message : Sorry, we could not reach the Netflix service . Please try again later (-93)

So you locked the bootloader instead of following the posts to install and use Netflix on a rooted device?
