Update base ROM of windows mobile - Touch CDMA Windows Mobile ROM Development

Is it possible to update the windows mobile base, for e.g. my windows mobile is at 19208 to the latest 20983 or so... without completely erasing all data on my windows mobile by doing a re-install ?
i usually like the original sprint version and i just install a couple of apps i like, i am not a chef or a enthusiastic ROM flasher and am happy with what i have.. just want to upgrade to the latest base package if possible without having to re-install everything.

No, it isn't possible. You need to reflash, and you really won't see any difference. The only ROMs that have new bases are the custom ROMs, or you could just dump a stock sprint rom and swap the sys and recook it, but it you won't notice any real changes, other than a speed improvement maybe.

Porting Android ROM to Diamond

Hi all!
I've been part of your community for the last few months and am just beginning to get a grasp of how things work.
To sum up my situation now...I had the diamond,but it was broken and then bought the hero not knowing the diamond could be fixed.When I got my diamond back from repair though I thought about,you know,doing a little hacking on it.So I've been flashing ROMs and,of course,have tried android.
I know some of you will say "Why not root the hero and flash a custom ROM on it too?".BUT!I want to keep my hero stock,mostly because of warranty issues and cause I don't want to brick it (always possible,right?).So,having the diamond available for everything and having loved android after hating WinMo,I thought about trying to port an android ROM to it.I've tried all possible android "installations"(so to say,it's never actually installed) and have liked Myn's Warm Donut most of all.Then the idea crossed my mind...As there are so many wanderful android ROMs,why not have one on the diamond?
I am thinking about trying to port either Team Villain's SuperHero or Exit93's Kimera 1.8 from hero,but I haven't got any past unzipping the ROM file!
So,what next?What do I do?If anyone wants to help you're welcome!After all I have thought of it as a community work product!
flashing an android rom isn't possible..for now...but if you want to port an android rom you should start from a rom of the g1...then if you want to do system.sqsh you need a linux distribution and sqsh tools..to use it in a ext2 partition i don't know
I am aware of the situation my friend!I know that,unfortunately,android can't be flashed on the diamond...I just want to make it run on the diamond,through haret!
And for the other thing you said about my PC's OS,I use Ubuntu mainly(much better than Windows,believe me!) and Windows 7 once in a while...So,where do I start from?

if you run haret.exe to start android, the WM will be completely shut down. wm is just used to initialise the stuff for android. u can use a full WM, no need to have an extralite one

Anyone knows what I need to replace to get Myn's Warm Eclair running on the diamond(from ext2/3 partition,NoSquash method)???

This is in progress. I managed to get it running till boot animation and this - unfortunately - is relooping. But I've uploaded ito to the dev (=Myn) so he can perhaps fix this
Did you check with adb logcat ? The last time I had some loopings I had some wrong permissions on /etc/dbus.conf.
adb shell , chmod 755 on the file fixed it
Don't know guys,I'm not an expert!
One thing that has come to my attention is that your SuperHero ROM vatoloco might have problems only because of the Sense UI.Try deleting Rosie.apk and Rosie.odex from /system/apps and try again.Haven't tried it yet.Not that I don't like SuperEclair,but wouldn't it be better to have two nice Android Roms instead of one?

Try this one
(Also this one seems to be good enough but i havent tested it out yet)
Its the best rom i have tested so far with absolutely no bugs and no bloatware and is truly super smooth
Only known bugs are the following: (which are not even worth mentioning but I'm giving details just as a disclaimer and of its possible consequences)
1. If you are thinking to flash emperor tweaks (god mod) to make it feel even more cool and smooth then you need to withdraw your thoughts, as i did flashed the same but it left my mobile hotspot unusable(which i had to fix by reinstallation of this rom) and also i didnt noticed any performance/battery difference after flashing it..so be away from messing with system/kernel data as it can modify your rom bringing in new fresh bugs, unless you are a pro in these type of things..
2. You will be required to install 3rd party applications to view/open/extract files such as zip, apk, pdf as the zip archiver is corrupted in solid explorer(comes pre installed) and pdf viewer isnt available
Otherwise everything is perfect!

Best clean / stock ROMs? (Mid-2018 Edition)

I have an old T-Mo S4 on 4.something and would like to play with some custom ROMs. I see that there are several ROMs but am not sure which one to start on.
What's the cleanest, most compatible, stock-like ROM for the S4? Preferably Android 7.x or newer.
Additionally, is there a simple way of reverting back to an official T-Mobile ROM?
I went with lineage, used it for a couple of phones. It's currently in active development, root is optional so I think safetynet is not an issue. I think a couple of other ROMs are based on lineage, so I just stick with them.
As for reverting back I don't know. I had to download stock for an old phone and flash back, this time I tried backing up stock, but didn't back up stock recovery, didn't think of it and not sure if I can. I don't know if my backup of stock will work if I try to flash back. Still pretty new to all of this, or maybe not new so much as I'm not a developer and I'm trying to follow as best I can.

I flashed AlaskaLinuxUser's [ROM][7.1.1] SlimRoms N [jfltetmo] build on my bone-stock SGH-M919 a week ago. It's my daily driver, so I'm glad the 7.1.1 Slimroms ROM has proven to be lean and stable.
It carries the same SGH-M919 model number so IR blaster apps are available.
It is not rooted, so corporate sector apps don't have a cow over security.
It is easily rooted using the recover-flashable SuperSU zip, and easily unrooted inside the SuperSU app.
Portable Hotspot works well, although only in the 2.4GHz band.
Media players are absent (slim indeed), so I had to download AOSP Music+ etc.
Wi-Fi Calling does not work :crying: due to not having T-Mo's proprietary app.
TWRP can backup and restore the whole phone using an SD card. You'll need around 7GB free on the card.

Have you attempted to manually get Wi-Fi Calling working? There are plenty of stock devices - the Moto G6 for example - where Wi-Fi Calling works.

Has anyone done a stability/basic functionality comparison of ROMs ?

I have been hanging around XDA for past 1 week or so, and have spent numerous hours in understanding Android/rooting/ROMs etc. As a software engineer, i had the basic background, to catch up on Android platform, which is new to me. Having covered everything here from "Intro to XDA/beginners" to Phone specific details, here is some questions, as i tread carefully into Android tinkering.
I have held onto an aging Tmobile S4, trying to avoid buying a new phone. Still running stock m919uvsfqa1 baseband (OTA early 2017). This was ok, since I do not play games / stream video / run social media apps etc. After 4 years of running acceptably, this phone started misbehaving in 2017. No hardware or software changes other than the factory reset to wipe data/cache (in last few days). Restored all apps/data, using Samsung smartswitch (I will write a guide on this later, as a thank you & give back, to XDA community). Phone seems to be revived after this factor reset/restore. I have 3 questions :
If i am only interested in stability / integrity / functionality in phone, should i stick to stock kitkat 4.4.4 (OR) should i risk it and upgrade to Oreo based LineageOS 15.1 (which i found on xda as End-of-Life) ?? (OR) any other custom rom recommendations (like marshmallow SlimRom) ? In my limited knowledge in reading various threads on XDA, i find only these two roms mentioned for stability.
In any case, i am considering rooting with CF-Auto-root, to get SuperSU and remove bloat/ads...... Perhaps i can install antivirus apps, since i won't be running the latest security patches available in Oreo (if i run older versions of custom ROM). Would you advise this for a Software engineer, who is newbie to Android ? (OR) simply play it safe and stick to the bloatware/stock ? (Note: I have already gone through guides on "what apps to install after rooting".)
CF-auto-root will stick to stock recovery. Is there any benefit for me in installing TWRP ?

USING STOCK APP's WITH CUSTOM ROM

We all love using custom rom's to improve our device. But every now and then I will go back to stock rom. Why?
Samsung make great apps!
I make a backup of various stock apps and then try to install them on the custom rom. It doesn't work.
.
How can I get stock apps to run on custom rom's?

The depths to which Samsung (for better or for worse) customise the Android OS on thier devices is what allows them to so deeply integrate thier own apps into the OS. This is what allows them to have proprietry features such as the S-pen recognised throughout the OS and perform specific functions in thier own apps, and also why such proprietry features, such as the S-pen, often don't work as expected (if at all) in apps that Samsung didn't develop.
Hopefully you can understand now why you can't install applications from a Samsung stock ROM on a custom ROM; the apps require functionality built into the stock rom itself.
Ok, I get it. S-pen not possible.
Is it the same for other apps? Like Music?
Another thought I had, and I don't know anything about compiling ROM's, but can you modify a stock ROM to have the improvements of a custom ROM? Therefore keeping stock apps.
There's a handful of independent apps which employ or require a pen.
The Samsung drawing app is an outdated version of a MicrographX or Adobe app in the store. But in the OS itself, the pen can just be used instead of the fingers, but with the digitizer's precision.
