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

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?
Why is it that there isn't just one version of android that will install on all phones? I mean, you can install windows on any pc regardless of spec and it automatically finds drivers for internal parts and makes them work? why can't this be done for android? would be miles easy for developers if you could just take a rom from say a dell streak and put it on say a galaxy s and vice versa, seems ****ing retarded to me that this isn't the case with android? Love my streak and android as a whole, but would be so much easier if the updates were dependant on the companies that made the phone and were just dependent on when google updates the software!!

Haha, first of all, are you genuinely serious? I loved the os of the ps3 why cant I have that on my xbox 360, come on mate, really. If that was the case, then we would probably just need 1 type of phone with every release of android software, example iphone.
Android allows people to have a nice choice of phones from different manufacturers.
I personally, think android is 10 times better than any other simply because of the control the users have, we can purchase an android phone and customize the hell out of it to our liking, yet you have no choice to jailbreak an iphone to have half the options android users get out the box.

Yes in a perfect world that would work, "one OS for any phone" but the truth of the matter is that it is a driver issue, and manufacturers want to make a profit. There are too many different manufacturers of components and not all of them are compatible with each other, get out dated or don't meet recommended minimal specs. Example is trying to put Windows 7 on a P2 machine. Maybe it will install, but you are not going to get much if any of the benefits of the new OS. Or if you put win 7 on a Mac. Sure it will work, but it is not going to be on a machine that it was designed to run on spec wise. Believe me, I wish it was that simple, but unfortunately it is not. We can dream though.
It has a lot to do with the drivers, unless every phone was identical internally (or each generation identical internally) there are no drivers for that specific device.
PCs are much more standardized when it comes to hardware working with drivers. Most important components like video/audio/ I/O have standard fallback modes and their specific drivers. That's why you can install windows or linux or whatever on a system and at least expect it to boot and most of the stuff to work. They have generic drivers that will do the minimum required for it to function, but not much more.
From a user perspective drivers are much more diffucult with regards to *nix then with windows, this is especially true with regards to android (as it uses the linux kernel)
Windows has standardized (as in they have published the specs and adhere to it) driver frameworks and spend a good deal of testing time making sure 3rd party drivers will remain reasonably compatable. Usually it goes smoothly enough when releasing a new standard, when it goes bad you get what happened with vista where the drivers were the main cause of instability. Most of the time you can use drivers written for win 95 on win7 x86 and there's still a fair chance it might STILL work depending on how well the driver was written (this is a gross oversimplification, there's an entire class of win 9x drivers that wont work, but the other class will).
With linux driver compability is much less clear cut, many important drivers are available as source, and it's very possible (but requires a fair deal of planning ahead) to build a pc and only use source code drivers.
If something is only available as binary drivers you're at the mercy of the manufacturer to keep it updated and working.
This is why android is so difficult to roll out timely updates. The kernels in 2.2 are very different from 2.3/3.x and rewriting the drivers for it is what accounts for ~90% of the work (assuming your device is powerful enough to update in the first place)
The full driver sourcecode isnt often made available for android devices, so you either have to spend time writing your own or attempting to adapt the binary drivers to make it work. This is what is happening with streakdroid 2.x
The other critical point is that the bootloader must be willing to load 3rd party code.
There's a fair amount of devices that have had android ported to them because they were:
1) Able to load 3rd party code (either by hacking the bootloader or it allowing it on it's own)
2) They either had comparable drivers or were willing/able to write their own
3) There were enough devs to take the time to accomplish this in the first place
4) Android is open source so it's possible to write your own drivers in the first place (techinally all you might need is the driver sdk, but no mobile os has only a driver sdk available, it's either all or nothing)
Being open source has absolutely nothing to do with being able to install it on any device.
Winmo 6.5 is closed source (sorta, it's somewhat like shared-source) but it's just as easy to port over. But there's little to no interest to porting it to new devices.
Win8/arm might be like how windows is on the pc IF they keep drivers the way they are. If ms decides to incorporate them the way linux does it wont be any different then what android is experiencing now (though it's kinda unlikely, windows has always loaded drivers as seperate modules, and they're likely actively paying attention to that with win8)
I will just add that in my very humble opinion the OP wasnt by NO MEANS asking a dumb question (and it would rule to have standardized drivers for phones)
(and btw, great writeup manii. this might as well fit in some android related blog.)

O M G!!! android fanboys!! your worst than apple fanboys, when did I even mention the iphone or what makes android so good? or installing other peoples software on to other hardware, I'm only talking about android and its phones you turn everything into android is better than ios blah blah blah blah blah!! Shut the **** up and go to another thread!!
The other people in the thread, yeah I kinda knew it was down to driver issues, but I didn't think it was that complex. Android imo is the best os I've ever experience in my life, even better than windows 7. But for me, I actually think the only 1 draw back the os has, is the fragmentation of the updates. Is this possiblity of one android os to work on all android phones, so you can just download the update.pkg from google and just install it on any android phone, or is this something that was never intended and because of how its developed its to late to go back and change this? or is it something google has in the pipeline?

Well I am glad Alexander cleard that up. I totally see now tht he was referring to one android update for all "android" phones. Which in theory, would be nice and possibe be the solution to so mny segmented releases.
Android fanboy?? Grow up, first of all I wont as you say **** off to another thread, you didnt get my point, but thats ok I can tell by your answer and generally by your original question that your not that bright, thats ok buddy.
I own an iphone 4, to run apples os I have to own an apple product (the phone) which for me is too small, I would like a bigger screen, so im stuck.
With android different manafacturers are in competition for what the people want and offer a huge variety of phones. Yes its a bit of a pain in the arse to install custom roms on them but once you know how its pretty easy.
At the end of the day to have one os that would go on any phone would be nice but then really whats the point in having a whole bunch of different phones. I like the way android is, I own as I said a earlier an iphone 4 and a dell streak, I find myself using the dell more, simply because I can make it my own.
Also ....me fanboy, you said you like android better than windows...the most popular os al over yhe world.

Yeah I know, coming from having the dell streak, and only having one upgrade while I've had the phone, I just can't understand why phone manufacturers go to all this trouble creating there own version of android when they could easily outsource this part of the phone to Google. I'm sure it would also make it easier for app developers to make there app work on all android phones. Seems so strange to me growing up with windows and being able to just buy a new pc and just get your windows cd out and bosh on windows, and it works. Does anyone know if this will ever happen or do the phone manufacturers want to have there own version of android, so they can fill it with there own apps?
To me even if they did still want there own versions of android, they should still give you the option of returning to stock android and just going to google for the update.

Your saying I'm not bright, but your comment to my original question had no relevance to what I was asking at all, you didn't even slightly attempt to answer what I had asked.
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!
Android LolliCrap 5.02 has totally screwed over my N7 2012 8GB, LolliCrap OS and accompanying support apps like Google Play are such Bloatware that none of my apps can update (insufficient space BS) when I had 1GB free before with OS 4.4.4!! Beside I HATE the new interface, it's SLOOOOOOOW and is some kind of nightmare! My M7 8GB is essentially BRICKED and useless now!! I hate you Google!
I also have a 2012 N7 32GB still running HAPPILY 4.4.4 and I want to keep it that way and NOT Screw it over too with any version of 5.x
HOW can I block the download of LolliCrap 5.x so it's not sitting there taking up Memory space because I will never install it and how can I block all future Android OS updates??? I'd rather NOT Root if at all possible, I'm not sure I'm technically qualified to Root my N7's.
I used to be a huge fan of Google and Android, this POS LolliCrap really has me pissed off .... I just may go and buy the "enemy" iFad Mini now!!

Without root, you can't block the updates. I'm using a custom 5.0 rom on my 2012 N7 and it's actually pretty snappy. I also changed the file system to F2FS and cranked up the GPU speeds though so that might have something to do with it. The Nexus stuff is one of the easiest things to root out there. I believe there are ways to do so without even unlocking the bootloader, which will require wiping the device completely. There are tool kits in the forum for your device that should help you do this with minimal effort.
Rooting is something I have not even attempted, can anyone recommend a tutorial, video and how to accomplish the rooting process on a N7 2012 for a newbie to rooting?? I've been in IT, but the hardware end, so I'm not tech challenged, just no experience on the SW Hacking side. I've got to get my N7 2012 32GB model blocked before it's devastated by 5.02 too!!
I'd also like to "Revert" my already "attacked" N7 8GB 2012 back to KitKat 4.4.4, is that possible? I've looked at Android OS DL's but which model name is the 2012 N7? "nakasi" or which??
Any help and suggestions from the experts on the forum appreciated.

This tool / thread will have everything you need. You can root and downgrade with it. The "manual" way is not difficult either. You were correct, it is the "nakasi" model. Just need the drivers installed, extract the folder from the download (use 7zip if you don't have an app on your PC already for those kinds of files), reboot to the bootloader screen (power off then power on by holding Vol Down and Power), plug into the PC and make sure the drivers load, then double click the flash-all.bat file in the folder and let it do it's thing.
Thanks.
Gentlemen,
Thanks for all the information and I will review the links you supplied and I will take a shot at Rooting my 2 N7 2012's to keep any nasty 5.0x updates off until Google comes to their senses! Serously, 8 days after Android 5.02 invaded my N7 8GB, it still runs like crap, balks, stalls, crashes, even Services crashes and stalls routinely. .... Google has made a mess of this version of Android OS 5.x, damn them. All just to serve their stupid "wearable" as I have read on several Android sites. Google is turning into CrApple.

I often find issues like that are caused from not resetting your device after OTAs. This kind of thing happens often enough between jumping OS versions, and is not just for the Nexus, but I've seen and read about it for every manufacturer, and even for Apple devices. There are plenty of people using Lollipop on the N7 without issues. Just every device is a bit different, even before you start adding your own apps and data.

I beg to greatly differ with your opinion regarding the number of Nexus owners (at least older models) having problems with Lollipop OS, along with owners of other brands of phones and tablets. While looking for reason for all the problems I've experienced and how to fix or revert back to KitKat 4.4.4 (because it worked flawlessly) and how to block further Lollicrap 5.0x updates, I've "Googled" and visited at least 30 of 40 different forums, blogs, postings and news reports that EVERYONE chastises, complains and hates Lollicrap 5.0x. Even Bloomberg News has runs a few news stories about why everyone hates Android 5.0x Lollipop and won;t use it. Several Tech writers have pointed out that the main purpose of Lollicrap 5.0x is to promote Google's android based "Wearable" and obviously from all the complaints by us, we've been sacrificed for their greed.
Sorry, If I got to wipe out all my app installs and start all over again with a "reset", I won't waste my time with Buggy and Kluged LolliCrAp 5.0x anything and these will be the last Google product I'll ever buy ..... they've become CrApple! All for the money of it and screw the previous model owners. My next new Tablet will be a Surface Pro.

Human nature - people are more likely to post complaining about things than complimenting them. Name an update on any device that you can't find people having issues with. Nature of the beast. But as I mentioned, the problems you are experiencing are very typical of issues with OTA updates and not factory resetting the device.

But you also have to take into account, that the vast majority of any device users, especially Smart Phones and Tablets, are not technologically "equipped" and DON'T B n C on-line and don't do postings looking for help, they just get pissed and move to another device or OS. So I postulate that all these hundreds of posts are an accurate reflection of the total percentage of people having issues with Android 5.0x and that since the tech media is taking note of it, it's the true nature of the problems. Sorry, my N7 2012 was pristine, ran perfectly under KitKat 4.4.4. If I'm having problems after and OTA update, so are the majority. It's just common sense and the odds.

So many leaps of logic, assumptions, and lack of understanding of how software updates work here, it's not even worth getting into. If you need help downgrading, I'd be more than happy to help though. You can hit me up on Hangouts @ my screen name if you'd like.
Apparently the 5.02 Lollicrap Update is down loaded to your N7 (maybe other devices as well) without your permission when connected online.
Where is it stored as a file, in what folder and can it be deleted, prior to Rooting the N7?
I'd like help with Rooting both of my N7's (2012's), returning one back to KitKat 4.4.4 and keeping the other 32GB 2012 N7 from ever being updated without my permission.
Thanks

It should be in the /cache folder, which you won't have access to without root.
http://forum.xda-developers.com/showthread.php?t=1766475
Everything you need will be in that thread. As long as the drivers are loaded correctly and you have a good USB cable, the toolkit should be able to do everything else as far as rooting and downgrading. Once you are rooted, then I think you should be able to stop notifications/downloads of the updates by following this 1st post:
http://forum.xda-developers.com/showthread.php?t=2429820
and / or might need to do this too:
http://forum.xda-developers.com/showpost.php?p=53169162&postcount=21
Or install a custom rom.
I'm not so cool with "Leaps" of logic in your instructions that seem to contain a lot of "I think", "should be ale to", or "and / or might need to do this too", or "Or install a custom rom". I've never Rooted anything, this seems more like guess work than a proven method and I'm not about to sacrifice my working 32GB N7 with KitKat 4.4.4 "experimenting".
By this loose method you're advising, my logic in saying the majority of Android users are pissed (referenced dozens and dozens of forum sites) but most silent about LolliCrap screwing up their devices, is like the proven theory of relativity.
I'll keep looking for a forum thread by someone that has, with no "might have to", or "should's" in the process.
Thanks anyway.

Sorry for not being more clear.
The update zip IS in the /cache folder, which you won't have access to without root.
The toolkit on from the link I provided has nothing to do with guess work as it is the easiest way to downgrade and root and has everything you need from the drivers to the root files to being able to download the 4.4.4 firmware and flash for you with very minimal interaction. As far as the notifications go, some people get away with one method, some have to do both. If you would feel more comfortable with someone helping via TeamViewer, I'd be willing to. I literally do this kind of stuff as a job and have experience with every kind of flashing, modding, upgrades, downgrades, etc for 100s of devices, as well as owning the same tablet you have.
Thanks for the clarifications, I'll download the Toolkit and run it to familiarize myself with it. If it looks confusing to me, I'll take you up on the offer to help using TeamViewer. I've used TV a few times with my IT clients.
Do you know which cashe folder Android stores the updates in? And once rooted and updates blocked, can I just delete that 5.02 file (I'm think my other 2012 N7 32GB which has not been updated)??
It's just in the /cache folder in the root of the OS. Yes, you can delete it without issue, though it's not going to give you any more usable apace as it's a different partition of the device that the normal data you save doesn't have access to. Still, might as well delete it.

It's been a while and I still haven't Rooted my Nexus 7, been researching the mechanics of how to do it and what methods are available that a complete "rooting newbee" can use without getting over my head in quicksand and a bricked N7 (2012) instead of one taken back to Kitkat 4.4.4 from a screwed up buggy 5.02 OTA update.
I was looking at a tutorial for using " Wugfresh" tool and a comment was made that "Unlocking will wipe the device.". Is this true? Is this always the case when rooting and unlocking?
I don't want to "wipe" my N7, just root it and return it to 4.4.4.
I also read that the boot loader in the factory 4.4.4 is faulty and a lot of girations are needed to reinstall 4.4.4. Has anyone experienced this?
Appreciate the thoughts and ideas.

Literally just finished helping someone with downgrading back from LP because it wasn't working well for them either. You absolutely have to unlock the bootloader, which will wipe the device, no matter what you want to do - root / recovery / downgrade / etc. This is not an option as it is a security feature. There are so many ways to back up most of your stuff that it's really not THAT big of a deal. There are apps, Google, cloud storage, etc.
Yeah in doing my "research" on rooting to turn back the calendar to Kitkat 4.4.4 I've read more and more pretty pissed off N7 owners, seems to have hit the 2012 and 2013 model owners the most grievously.
Question then if I backup - since I'm on LP 5.02 on my 8GB N7 (2012) already, when I do a back up won't it also take with some of the LP oriented settings?
Is there a highly preferred BU method that will take everything from data, settings and apps so after I root and reinstall (flash?) 4.4.4 on a wiped N7 it puts everything back? Is there a BU method I can use to BU's to my PC, rather than a cloud? (I don't have a 8GB "cloud account with anyone)
Thanks very much.
I'll have the chance to buy this phone for 160€. Normally I investigate around if the community enjoys the phone if there's development for it in custom roms and what's the status on the bootloader but it's getting complicated.
From what I've heard, Huawei stopped offering the chance for unlocking the bootloader for its phones, it is still possible with this one? If yes, completely? Can we do whatever we want or are we limited? I've browsed and seen treble support for it, is it working well? If you are using a P20lite with a treble rom, what works and what doesn't for you?
I'll still be looking for info to my own questions and even more but if you have some spare minutes, own the phone and have the answers I'm looking for, care to help please?
If it's worth it? For that price and as of right now, definitely yes. It's a well built phone for the price, the glass on the back is a bit bad of course in terms of durability but allows for better network possibilities which plastic does not. In terms of ROMS and recoveries the phone already has them which at this time is amazing, although development always depend on the true developers that stay up to date and that give their best to keep projects up to date.
Boot loader is a problem as of right now for those who have no key to unlock it. There is some paid software that can do it like Funky Huawei and others...Although I think Huawei might change it or find a better solution to developers trying to develop some ROMS to their phones. Huawei only does this because of security since Android is full of vulnerabilities and they are not risking to lose against other companies like Apple.
Once you have a boot loader unlock code, yup you are free to do anything on your phone
As for the treble ROM's, in my humble opinion I think they have a lot to evolve right now due to bugs (talking in general, not only for our device), I think they are good alternatives to normal ROM's though, simpler to install and smoother.
What works and doesn't work you can see it at github, I can give you a link for a treble ROM created by phhusson developer at github https://github.com/phhusson/treble_experimentations/releases/tag/v108, look on the issues tab if you have any issues yourself. I personally love his work.
Resuming, it's still a perfect deal since the phone only launched a few months ago at 400 euros.
Although if you want full control of your phone and at the same time receive a lot of updates I honestly recommend Nokia - Android One phones
You probably already know but, don't let Chinese phones fool you, their build quality sucks, they might have more a bit powerful but after 1 or 2 years it's dead
Cheers,
AS
