Hi.
This is my first post on xda, and I am hoping to learn a lot whilst I am here.
I am not expecting any help here, but there has been small hype about getting android onto this phone. And I understand that you may be critical about noobs like me expecting an easy fix from you.
I appreciate that the idea makes no sense from many perspectives, this is mine.
I purchased the windows 7 phone 3 months ago, I was a complete idiot and fell for the sales pitch, the salesman promised me the earth, he said I would be able to WiFi Tether on the next update, he told me it would be better then the android evo 4 that I wanted.
As you are probably aware, I am a complete fool. I have however spent many hours on the phone with a certain mobile phone outlett, and my provider, neither will help. And I am stuck with the phone till 2013.
The phone's buyback price has gone down to 1/3rd what it was on the day I bought the phone.
I have now made it my mission to get this phone to run android. I feel so strongly I may even remove the windows logo from the bottom of my touch-screen.
I have already researched some, and expect days more research before I'll be able to do, whatever it is I need to do.
I am and will be keeping a log, of all my research, and hopefully can use what I learn to help people out later on.
So....
Any comments, or questions or support?
CleverNoob
I have picked up a few things. And therefore want to clarify,
I don't want to dual boot the 2 OS's, I want to REMOVE windows 7 and replace it with Android.
From what I gather this means I need to develop an android ROM to work with the mozart, and then Flash it to the phone...?
So my logical mind tells me to look for the android ROM that works on the most similar spec phone.
I am however aware that the firmware or something is different in the mozart, from the HD7 and does not allow for certain android commands to work, therefore the ROM (gingerbread?) used on the HD7 will not be remotely compatible with the HD7?
It seems that there may be a few options for the actual flashing of the ROM already available... So I am going to concentrate on learning more about ROM development now.
If anyone wants to correct me, point me in the right direction, or hurl abuse at me... feel free to do so
I do not know all that much about ROM development.
What about drivers though? Sure it is fine for the chipset as there are Android devices with the same chipset (CPU and GPU)... Although the WiFi, bluetooth, radio etc. I guess it's built into the SoC?
Drivers for the screen, capacitive buttons, camera etc?
I think if you look around, you should be able to find a phone similar to htc mozart and the name which comes to my mind is Nexus one and htc desire...
Although it depends on you that you extract drivers from the OS of both of those android based phones then extract drivers from your mozart and compare if they have same chipset....
I really wonder if it's possible to do all this virtually instead of physically installing OSes on phones for development purposes.
You didnt give up did ya mate!
All of the Australia Telstra Community who got Conned into buying the Mozart over an iPhone due to This Service Provider not having a Contract with Apple are 'root'ing for your Success
just checking if i got it right...
you want android in the mozart just to enable wifi tethering.
well, FYI, its been done and done bro, just unlock your device and install any of the excellent custom ROMs here. my notebook is tethered to my mozart right now.
but if you want to further explore the capabilities of the hardware, no worries- many good samaritans are already doing that. explore the development forums here and thy shall learn!
take care!
Tethering is working now, even with Telstra and no unlocking (7720).
This is my first post too! I was about to post something like yours. I have an HTC Mozart too and I want to install an Android ROM on it though my reasons are different.
As a software developer I have no experience about ROM development but I'm very interested.
So what did you do until now? Any success?
As in the title, I recently purchase a new HTC phone, and it's built for ChinaTelecom(carrier). So i think most here haven't even heard about it and it's called:
--------HTC new Desire VC
--------aka HTC t238d
Now comes the problem!!
Before this phone which i got it nearly free, i always relied on my oldold milestone. Quite old fashioned but really good phone and the most important thing is that Milestone is a WORLDWIDE POPULAR phone, so cm7, miui, anything else, worked hard with it~ Long casual years with Milestone, even after some 3rd-party rom groups stopped supporting it, it still has got lots lots of fans and hackers work on it. Until the day i change my phone, i was extremely using almost-perfect ICS on my oldstone...
But the stone finally get exhausted at everything, everything is not smooth, not one more app is installable or the phone became veryvery not-usable... And this new one mentioned above is great at these points, quite good hardware, stock ics etc.
The main thread comes: I hate Chinese carrier stock roms, and I hate HTC Sence also... And I have been using cm7~9 nearly all the time and of course, it's my favorite. But i can't find my SPECIAL phone in the cm10(or 9) support list without doubt. And no foreign hackers works on it without doubt again. There do exist some Chinese developers making t238d custom roms but they are not good.
Let me explain, in China, both developers and customers prefer a thing they called Chinaly I suppose... They don't like stock android, i mean the google one, they split out the gapps with nothing left but lots of Chinese things instead, i.e the huge Tencent Empire products maybe you have heard. Even they hate holo style!! Millions and Millions of apps are fake-ios themed. I am totally minority so not a single locale developers like my idea indeed.
I like google, like cm, like HOLOed apps, like fake-vanilla things even. And CM becomes my last hope. I have to port it to my phone on my own...
What I got
--------totally pure Linux OpenSuse(i686/x86-64 both)
--------openJDK, gcc things
--------SDK,NDK thins
--------the great kitchen
--------repo init -u git://github.com/CyanogenMod/android.git -b jellybean , repo init -u git://github.com/CyanogenMod/android.git -b ics both (jb prefered, i love cutting-edge toys... but no suitable develop skill sadly)
--------primodd kernel sources from here: h t t p://htcdev.com/devcenter/downloads (search desire vc you will also find them)
Then i think i have got a prepared environment and both clean complete cm src and htc stock kernel src, that means i can port cm to my phone!
But, if I really can, what shall i do now.....Just a little advice will be very very appreciated, cause i've struggled with those problem for quite long time.
And if i suck, which means i just can't do what i want because of any reason, please tell me too.
Thank you guys anyway！
Everyone that asks this gets the same response. There are many basic porting guides all over the web. Google for some of those. Find a phone with a similar build type. Might get lucky and find a device you can build and it boots, then you just have to fix device specifics. You are attempting to embark on a new journey. I don't have your device. I can't really help. You need to figure out a lot of this on your own.
What lithid said also applies to the rest of us. We can't say "Oh right, edit this file, that file, and the other file, and viola you'll have a perfectly booting CyanogenMod." It takes some experience, a lot of reading, and a lot of trial and error. Also expect the device to be unusable/unbootable 90%+ of the time so if this is your primary device I suggest holding off on the development.
So short story: Google it.
Hi everyone
I have an LG Optimus Vu device and due to LG's tremendous support for this phone, the operating system is still ICS and the kernel version is 2.6.39 (even the I/O scheduler for this phone is set to noop, and there aren't any alternatives :| ). It could be all good and well if there aren't hundreds of crashes appearing every day about different applications, which is driving me crazy. I've searched and searched and it seems that there are no custom ROMs for this phone, nor is there any custom recovery application. I could barely find an application to root this phone.
To get to the point; I'm considering to make a custom ROM for this phone, but I am a noob in these kind of stuff.
I have the kernel source and the original ROM zip file. Since the original OS version is 4.0.4, is it possible to bring the required proprietary drivers from the original and use it in a newer Android version like 4.4.x?
Can I use Google's recent Tegra 3 kernel (3.10) and port those LG specific drivers from the older kernel?
Am I even starting this process in the correct way?
Any help is appreciated.

Hate to be the bearer of bad news, but you're pretty much stuck. LG has locked the bootloader on it and has said they have no plans on unlocking it. Since the phone is around a year and a half old or older, I'd imagine they aren't going to change their minds all of a sudden for the relatively small amount of people still using the phone.
http://forum.xda-developers.com/showthread.php?t=2055272 - discussion about your phone here
FYI
What is a bootloader?
The bootloader is the first thing that starts up when a phone is turned on. At its most basic level, a bootloader is the low-level software on your phone that keeps you from breaking it. It is used to check and verify the software running on your phone before it loads. Think of it like a security guard scanning all the code to make sure everything is in order. If you were to try to load software onto the phone that was not properly signed by the device vendor, the bootloader would detect that and refuse to install it on the device.
When we speak about locked bootloaders, the context is often used to give meaning to the term “locked.” Almost all phones ship from the factory with locked bootloaders, but some are encrypted as well. It is this encryption that most reports are referring to when using the term “locked.” If a bootloader is encrypted, users can’t unlock it to load custom software of any sort. The device will be restricted to running software ROMs provided by the manufacturer.
Now, there are ways to unlock or circumvent bootloaders in special situations, but with ones that have no dev support like yours, it's pretty much a lost cause and most likely way beyond your capabilities to figure out without spending 100s of hours of learning about Android stuff. This is not a knock on you or anything of the sort, but it is what it is. It is a very difficult thing to figure out encrypted bootloaders even for the most experienced android developers and hackers and depending on how they are encrypted, there just might not be a way (ask the older Moto phones, especially from VZW).

Two thumbs up for the detailed reply.
Shame really. The phone was released in November 2012 but there wasn't a single OS update...
I guess I would have to give up on that, but I'm interested in system level developments for both Android and desktop systems. Any idea where to start?

Yea, it does suck. That's one of the downfalls to making 8 million different phones. You have no incentive ($$$), no interest, and no manpower to be able to update them all in a reasonable fashion. But it's not like LG is alone. All of the manufacturers have had decent phones just...disappear in regards to updates or anything of the sort.
As far as getting started, there is a ton of info right here on XDA:

Modify hashes?
Hi!
Sorry for digging out a dead thread, but for the p895 probably all threads are more or less dead...
I wonder if it is really necessary to decrypt the bootloader. Since it must be able to boot different versions of the stock roms, it would probably only calculate a hash value of some files and compare that to a value stored elsewhere.
By comparing different versions of stock roms it might be possible to get some information about what files are hashed. If it is a standard hash algorithm and the comparison value the bootloader uses is stored in plain text (hope....!) there might be an atack vector in
comparing several known plain texts.
I also noticed, that the p895 has a "software integrity check" in the hidden menu that shows has values for some (a lot) of files. these hash values are likely already calculated when entering that menu option (i am pretty certain because they show immediately), so they might belong to the files checked at boot time and also hint to the hash algorith used.
The idea is to calculate a hash value for the custom rom and put it in the appropriate place so the bootloader thinks of the rom as an update.
These are just vage ideas, but i have no intention whatsoever to buy a new phone anytime soon and I guess I could as well spend "some" time tinkering and learning the tech details...
thank you!
The Mozilla Flame runs Firefox OS, which is pretty limited in terms of usability at the moment due to lack of apps and general support. The boot loader is completely unlocked (adb/fastboot), the kernel is an Android Kernel derivative which is available and the device uses Android drivers which are also available. Due to these factors, I assume that it is possible to put Android on the Mozilla Flame. I've never built a ROM in my life, not even for a supported device, so I stand no chance at trying to put Android on this on my own.
I've looked around Google and XDA, and all tutorials which I've come across seem to except that your device is currently already supported in one way or another, where there's no guides which even slightly hint towards building for a non-support device. So, what would I need to get going with this? Any help and advice is appreciated. Thanks.
Hi everyone,
I can't find a satisfactory answer on my favorite search engines, so I thought I'd come here and ask. Sorry if this question has already been put on the table, carved, sliced and gobbled, I couldn't find trace of it in the forum's search engine either.
My phone's a Leagoo T5c that will forever be stuck on Android 7.0, it seems, because the OEM has already lost interest, and because its SoC makes it difficult, if not downright impossible, to find a suitable custom ROM.
The latest ROM I could find and install on this phone goes back to August of 2018 (no-no, no typos), and its Security Update is even one month older (July 2018).
My question is in the title: Is it possible to install Security Updates without reinstalling/updating/upgrading the firmware itself, like you would in, say, Windows or any other OS, I presume?

With android 10 were introduced Google play security updates that lets you received security updates (not all of them unfortunately, some requires to upgrade) without updating the full OS. You can't do it because you're stuck with the wrong Android version
Hopefully you won't have any issues with hacking but consider buying a new phone when you'll get a chance
Security updates get rolled out as OTA by OEM/Carrier if they consider it's necessary. You can't force it. Theoretically, all Android smartphones should get around two years of security updates. However, the reality is often very different.
The Leagoo T5c is a small-budget phone what was sold for 99 USD - so more or less a disposable item. You cannot expect OEM/Carrier to have any interest in providing updates for such a phone.
Thank you both for your explanations. I understand that Android works differently when it comes to updating itself, mostly because Google isn't the only party to have a voice in the chapter; still, it's unnerving to see that the end-user is more or less captive anyway.
It kinda defeats the very purpose of an open-source OS, to have to wait for an OEM to release (or not) an update, when you could install the patches yourself.
As for buying another phone, well, as soon as I've got the dough, I will, believe me. Not because I'm dissatisfied with this one, but because I don't like the idea of totting around with a phone that hasn't seen a security update in over two years.
I'm also seriously considering moving to Ubuntu Touch, though there again, my phone's exotic platform could be problematic. Custom ROMs seems to be as complicated an avenue as others, too.
All in all, Android isn't what they sold me: It's not secure, it's not "free", it's just another way to make you shell out bucks for new hardware every couple years.
Android is just iOS without the eye-candy, you ask me...

Android isn't iOS precisely because you can break free from your OEM by flashing a custom ROM. You can develop one for almost any device as long as the OEM releases the kernel source code. And most OEM do (expect for some very unknown phones).
Custom ROMs like GrapheneOS are made to free you from google Services and are truly privacy oriented. And all of that is possible because Android is open source.
Trust me, the Android community has always worked actively to counter aging of their devices (including me).
Just buy a phone with a solid community behind and you'll be able to keep it up to date a looong time

I agree with you in principle, but if I must take an example: I have this Early 2006 MacBook Pro with a Core Duo CPU that precludes me from even installing Mac OS X 10.7 "Lion" on it, because the CPU is 32-bit-only, and Lion requires a 64-bit CPU.
The machine itself works very well, albeit a bit slowly, but then it's got only 2 GB of RAM and a 120-GB SSD. When I got fed-up with OS X applications not updating/upgrading and Firefox addons not installing because my copy of Firefox was too old, I partitioned the SSD, installed rEFInd as boot manager, and installed Zorin 15.2 (now 15.3) Lite 32-bit.
I now spend more time on the Linux side of this Mac than on the OS X side, and updating/upgrading it is a breeze, either via the dedicated application or in Terminal. I know there'll be an end-of-the-line there too, someday, but at least I'll keep using this Mac until it truly dies on me, not when Apple tells me it's dead.
This, for me, is the very essence of open-source: Not just the fact that it's free, but that you can revive an old machine and keep it running long after Apple et al have decided that it had gone the way of the dinosaurs.
The same doesn't apply to Android, alas. Here, you must have a compatible SoC/chipset/what-have-you, a Treble-compatible device, you must have this, you must have that...
In the end, only a fraction of Android users really get to enjoy everything their device has to offer for as long as they choose; the others just pop into the nearest phone store, be it brick-and-mortar or cyber, and must produce their credit card.
My question was as much a challenge to myself as anything else. I would really like to learn how Android works, but the tutorials and articles I've found here and there are all a bit cryptic.
That's why I'm regularly prowling this forum, I guess.
"Hunting high and low", as the song goes... :laugh:
yep, good question but google & manufactures are in it for the moola not the users 2 yr old phone.

Don't I know it! It's true that even budget phones have decent specs nowadays, still, why dump a perfectly functioning phone simply because you can't update/upgrade the software?
I understand Google's rationale, of course: They invest tons of money year after year after year to keep the whole boat afloat, and they need a steady income. OK. Still, to not be able to keep your phone ***safe*** is a no-go for me.
I'm seriously beginning to think about installing Ubuntu Touch on the device. I think I'm going to try that next weekend.
I'll probably come back here with my eyes red, asking for help in unbricking my phone, though.
Stay tuned! :good:
A followup, if you are mindful of your own security it's conceivable to get more usage of that android. I don't use a banking app, but if need be use a good browser( thats updated of course) And update all often used apps via playstore. I'm still running Oreo on my phone. FYI you iOS ppl need to do critical updates asap
