Differences between WM6 OS Versions - General Questions and Answers

I am confused by the many different OS version for WM6 ROMs (20273 22222 19701). I did a search and the closest post I could find didn't really explain the reasons for different OS versions.
Is the latest the best and most stable?
Is there an OS changelist I can view somewhere?
Are the OS versions set by the ROM maker and shared by them?
Are the OS versions set by Microsoft or the device manufacturer that the OS came from?

the only real difference is windows mobile 6 and 6.1
then you have difference in radios provided by different carriers at different locations.
there isn't really a change list since there are only two official types.
if you download a rom from this site it will not be an official rom unless it says it is.
roms aren't updated like windows with service packs, you have to completely "delete" your operating sytem and info and load a new one...... which is why you won't get an update unless it is basically a new operating system.

Usually not. Nor are the numbers a guarantee of newness. Sometimes earlier numbers signify newer builds.

Not that I have seen. But as Joel said, the only real big difference is 6.0 and 6.1 . Other than that, builds usually feature bug fixes and/or speed tweaks. You are best off to watch the forum for a specific device. Most ROM cooks will post which build they are using, and most new ROMs will use the most recently released OSs. That way you can know the most recently released builds for that are working for that device.

No. ROM cookers (I assume you mean cookers) use various builds which they get from various places. Usually they get these ROMs dumped from recently released models, sometimes they get them because they have connections in the right places; like Microsoft, HTC, etc.

Good question. I don't know exactly, but I would assume that an OS comes from a combination of work in both companies.

Thanks for the quick replies.
Does anyone know of any threads that talk about OS version differences?
How does a ROM cooker go about choosing an OS version?

like we said, no there isn't an os version difference.
The differences are 6 and 6.1 or from different phones.
ROM cookers choose ROMs on features they like or what they have available.
A good way to start would be to just find a good ultra lite rom and build from there

Bluetooth tabs gone

I'm missing the FTP and SECURITY tabs in the Bluetooth settings program. Is there any newer software for this or is it hidden somehow?

what rom are you using and on what device, i only ask because older builds of win6.1 dont have the tabs, newer ones did. Someone asked me this on a prophet rom, he changed rom to a newer one and it had the said tabs

I'm using a rom cooked by Rugal at eten-users.eu (X500)
CE OS: 5.2.21109 (Build 21109.1.5.0)
I'd rather not reinstall my rom, I can live with the few tabs.. but if I can fix it with some updated app I'd love to.. I also can't receive files at all atm but I read there was a fix for that out there.. gonna try it later this week when I get the time.

Android 10 / Q

Is it possible to create an AOSP version of Android Q from the beta version for the HTC U11?
Is it possible to create a driver package for the HTC U11, so that with coming versions that package can be included in building a ROM? Or, was that thought too easy? ?

very much looking forward to
Pixel 2 Series basically have the same hardware as the U11. So it's very possible as long as there is a dev who's interested in making one for U11.
That's why I bought a HTC U11 instead of the Pixel 2 ?
Is there a developer interested in creating one? ?
It's time :laugh:
https://developers.google.com/android/images
With this image, can a ROM being build?
I would love how to learn how to port ROM's & new android versions, I can't find any up-to-date documentation or walkthrough's for Pie or Q , I'm curious how people do it. Can any of the U11 dev's direct me to any information or where to even start?
The thought of running my trusty U11 on Q is enticing, I'm willing to learn and help any dev's out there to get a Q ROM up and running.
I know it must be possible, the HTC M8 has got pie ROM's on the go!:fingers-crossed:
Although the u11 hardware is similar to pixel 2,
But the software has huge differences between Vendor and Vendor.
HTC usually has special drivers, which greatly increases the difficulty of creating a new version of Android.
I saw yesterday a friend with his phone with android 10 installed. I'm really jealous , how is this possible? The only useful information i can find is Lineage OS 17, which is not available for public release.

Guide to unlock your MEIZU 16 Series' bootloader

Update: DO NOT TRY TO PAY!!! THE GUIDE IS BADLY OUTDATED. JUST USE THE RESOURCES AND FREE METHODS.
If you want to try the paid method, you should definitely get in touch with the seller first. I don't know whether the previous sellers are active or not.
If you want to inform me of something important, please `@me`, (I missed many replies in the past years)
---
There seems to exist a new method: It is said to work on Qualcomm devices.
First, dump frp partion, then edit the value to 1 at 7fff0, finally, flash the modified frp image. then you can use fastboot command to unlock your phone.
This new method shall work for for ODM devices like 16T, 16x, 16xs and Note9 and so on. see FRP Method.
Below is the original post:
The original post has been removed, since it's outdated and I almost finished the English version tutorial on Github.
You can see it on github.
BTW, it's really difficult to use XDA's text editor.
You can download the TWRP of 16s here
it's a start, is there anyone who has already tried a gsi?
Good news for us Meizu users! Hope this is just a first step towards some good modding ?
Will this also work on Meizu Note 9?

A new method has been released on 4pda, which supports almost all MEIZU devices using Qualcomm Proccessor. This is the original link 4pda.ru/forum/index.php?showtopic=961552&st=960#entry90949224

Sure, the new method applies to almost all devices, all versions. You can have a look at my github repository. I will edit the original post as soon as I can post links. BTW, is there any netdisk you guys use frequently? I don't know where to put the TWRP so that you can download easily.

You can use yandex.disk or google drive.
But you say about downgrade. Does the new method ignore the firmware version ?

yes, the new method applies to almost all versions, I have not updated the original post, because I have not prepared the English Version well on Github. You can have a look at github.com/sukanka/MEIZU16S_unlock_tutorial/wiki/Guide-to-Unlock-Your-MEIZU-Device
A new tutorial has been released on github
I must post in this way, as I'm not allowed to post links now. The Tutorial is at

There seems to be custom ROMs for MEIZU 16th, I've seen Lineage, havoc, and mokee before. But i don't know how do these ROMs work. Anyway, I use 16s, not 16th. Besides, I don't know how to add a new phone category.
BTW, it's said that the kernel source of the 16 series will be released, maybe next year. And there are plans to upgrade the Android version of the 16 series.

You try another gsi rom? I want try pixel gsi or havoc, but I don't think was supported at 100%, probably lost taptic engine and other features... If have problems with this gsi and I want reinstall flyme stable, will be a problem?

No problem. If your phone becomes a brick, you can follow the unbrick tutorial to save your phone. But you are suggested to have glance at the tutorial before you go.
As reported by others, fingerprint and Mengine (taptic engine) don't work.
I am on havoc 2.9. Fingerprint mengine and mtp not work. But other features work fine

Difference between the numbers following HCT for rom versions?

What do they mean?
I've seen on the repository for HCT android 10 roms for example that there are ones that start HCT2 , HCT4, HCT7 etc. my rom on my device itself says HCT2 but when i 'updated' to a rom the manufacturer recommended me to it now says just HCT. so i'm a bit baffled about the numbers as they don't seem to bear much relevance to versions of the rom etc.
ok then, thanks everyone
I've asked the same question and never received an answer.
Did you want to install them and document your findings here?
Anyone...Bueller...
The launcher looks different on hct4 and 7

Android 12 was a major update. Before A12 there were major android versions. Where did you see small changes. Maybe not visually but under the hood A13 has a lot of changes.
A13 changes: https://developer.android.com/about/versions/13/summary
A12 changes: https://developer.android.com/about/versions/12/summary
There are so many roms because building roms are pretty easy. You can do it too. See lineage or pixel experience's how to build rom manual.
