Hello to you all people of XDA, firstly I must state that I've scoured the forums far and wide and have yet to find some valuable info regarding my problem.
So what we're doing is developing (or trying to, as is obvious from this post) a custom rom for the Galaxy S2 which would be used for a single medical application for sensor tracking and the processing and displaying of said data on the SGS2, while at the same time sending it to his/her doctor.
What we need to be able to achieve with this rom is to put it into the hands of the end-user (a chronical patient which will in turn be able to stay at home instead of being hospitalized) and be able to completely lock down the phone for his use (I know, it sounds terrible) so that he loses the phone/sms/games/youtube/internet functionality as we need the phone to run as stable and for as long as possible without any additional battery stress (the constant sending, processing and processing of data seems enough of a problem for now).
I've searched into some custom roms but we eventually came up with the need for a stock Samsung rom which could be modified as we want to.
See this is where the problem begins, we can't seem to get the phone rooted, the ROM customized and then unrooted again so that the phone can't be fiddled with anymore, except when it's completely dead and we need to fix it.
So to cap it all up:
It needs to allow for a custom load and bootscreen (I almost got this to work)
It needs to be completely locked down for the end user.
It has to have full BT, NFC and WiFi functionality
It has to be able to call out and reciev calls, but only to/from specific numbers (911, doctor, etc..)
It has to basically allow for 2-3 programs to be running, while the others simply don't exist on the phone.
I am terribly sorry if anything like this has been asked about before, I swear I put 2 days of me life into researching already.
Any help, any help at all, ideas and solutions, but mostly links are welcome.
Thank you and good day to all.
Just a detail, but the SGS2 doesn't have the NFC functionality. Project seems to be possible, I would look into CyanogenMod sources if I was you.

Why are you afraid of leaving the phone rooted and in hands of the patient?
Is he so uncritical that he can search the web and find means of unrooting a mobile phone and then get around to actually doing it?

Block all internet access apart from ones you want or you can just setup iptables rules, shouldnt need root apart from when setting it up
As far as removing programs, just delete the apks from the zip, or before you remove root. My sig has a list of all apks in a upto date rom and what they do.
You can use gemini app manager to control autoruns (stop them etc) also to block (hide and disable apps)
As far removing root, your best bet is to once you are done, use adb (from the android sdk) to remove the superuser.apk then flash the stock kernel back, as far as I know without superuser apps cant grain root permisions.
OR
This app will allow you to block any app behind a password
This app will block incoming and outgoing sms and calls on white and blacklists
Custom boot logo (the first screen before the animation)
Custom boot animation need to go into system/media, I am not sure about the format but there are loads around, like this thread has loads, stock kernel should support them.
I hope that helps
Most of that is easily possible.
If you listed the apps needing removed, the apk files just need deleted.
To control calls, you can use a third party app from market for that.
It's possible to have the custom rom unrooted, and easily flashed, regardless of how badly the phone gets rooted
Boot animation is easy anyway... If you can provide it in a zip like other ones (zip containing numbered png's) then it's a piece of cake.
A little bit of clever firewall stuff would prevent any web traffic, in or out, except to your defined server, which is obviously a concern when a phone is handling sensitive medical info.

The phones are going to be used by around 500.000 people in a year, it's not that we want to take anything away from the user, it's more about not having any problems with the firmware - like ever.
Thanks for all the help!

LucLucLuc, not sure where you live, but you're entering the patient confidentiality minefield with big, big boots.
Apart from the legal considerations, your question is definitely OS related and not device related.
I see what you want, but legally - where I live anyway - it's too much of a grey area to get involved with.
I use call recording a lot for referrals and info from other doctors, but I've always asked the other party if they're OK with it. I won't record patient conversations, and I won't accept any files whatsoever that have seen RIS or PACS first - not worth it.
Can't see it's worth your while, but I'd appreciate it if you keep me informed should you decide to work on it.
Big boots indeed
We are from Slovenia, Europe.
I'm actually just a student doing the research and some basic Android programming, thank god I wasn't let into the bigger of the projects
But yes, this project is a colaboration of several european firms and you can read more about it at chiron-project.eu - it's a very very interesting project afaic.
I don't think we'll be swimming with lawyer piranhas soon though, the project uses sensor data (which sorta is a privacy issue) which will be monitored on a tablet running Android (currently testing the Galaxy tab 10.1 - we were lucky to order one before Steve had another one of his fits), proccessed in real time and then stored on the central server, from where it will only be accessible by the patients doctor.
Patient consents are dealt with before we even start talking about mobile hospitalizations.
It's very encouraging to see some actual interest, if anyone wants to know more about anything related to this project contact me at [email protected]
Thanks again for all the help.
So, I've repurposed my old Nexus One as a wifi only device, and I want to be able to control it via my Evo 3D, but I can't seem to find an app for this specific use case.
I was hoping someone would know of an app to do this with. Primarily just want basic music controls but a full blown vnc would be cool if it worked well.
Also, if anyone knows an easy way to get rid of my signal bars and (no service) on the status bar that would be cool too.
First off, I apologize if this has been covered before in a thread. I spent about a half hour searching for my answer and was not able to either find it or understand which answer I was looking for.
I have in Taiwan a:
S3 GT-I9300
4.1.2
I9300XXELLA
3.0.31-899179
Rooted
No custom rom
(not sure what else you guys need to know)
I was simply curious if someone would point me in the right direction for the following problems. I use reverse tethering quite often with my smart phone as my office does not have WIFI and I enjoy watching sports games on my phone or listening to the radio broadcasts. I have a plan with a 5GB data limit and the video will eat that up pretty fast. So, whenever I use reverse tether, want to check for available wifi, or do any USB/Blue tooth tethering I have to go two or three menues deep into my settings and it's a tad annoying.
Is there a way I can customize the top drop down menu to replace some of the UI icons with ones that I actually want to use such as, "enable usb tether" or "see available wifi signals" or "turn on wifi hotspot?" I could remove Blocking Mode, or AllShare Cast as I never use them.
While I'm able to root phones (easy enough) I'm pretty clueless about custom Roms, how to use them, which ones are good, how to keep my phone protected when using them etc. There is such a huge amount of information about customizing the S3 on these forums, I just didn't know how to wade through it all to get the one customization that I want.
Again, sorry if I couldn't find the threat where this was discussed, and if there is a thread that answers this question well, I would appreciate someone pointing me in the right direction.
Cheers!
Not 100% sure, but maybe have a look into JKay Delux (you have to find the version for your firmware though). Otherwise another option could be to create a shortcut for your home screen via tasker that brings you directly into that menu.

Does tasker allow you to create shortcuts for any phone command? If so, that might be what I need.

if I am not wrong, most of them yes. At least it lets you control most of the functions (if you add Secure Settings PlugIn even more.)
I have an M8 from AT&T. I am using simple mobile as my carrier, which makes certain things not work like software update, TV remote, & mobile hotspot. It currently is running 5.0.2. I want to update to a very specific version of marshmallow that I had running on my HTC desire 530, branded with metropcs crap all over it. The reason I want to do this is bc on that desire 530, it had the ability to play YouTube audio after you open a new tab, app, or manually time out your screen. I want that functionality to be on my M8. I'm not sure which part of the software is responsible for that feature. Is it the firmware? The build? Will someone be able to explain how that works?

Porting over a ROM from a completely different device (or some aspects of that ROM) without a lot of development knowledge, really isn't a feasible thing to attempt.
There are xposed and Magisk modules that do exactly what you want (Youtube background play). And it's relatively easy to root, and install the Magisk or xposed module you desire.

It's true that being off AT&T kills the OTA update feature. However, you can still update by RUU, if you like. Check out the RUU section of my Index thread: https://forum.xda-developers.com/showthread.php?t=2751432
Mobile hotspot, you can get working if you root, and do the wifi hotspot/tethering mod; or alternately, install a custom ROM. WiFi hotspot is only limited on the stock AT&T software (or other US carrier stock software).
The Sense TV remote app doesn't work anymore, since HTC stopped supporting it. It's got nothing to do with switching to Simple Mobile. The phone's IR blaster will still work with other TV remote apps such as Peel and others.
So within the last couple days I purchase the LG v30. It's been a fantastic phone but there's one thing that I'm missing. From what I've heard and what I know so far, the smart settings option that allows you to turn on and turn off Bluetooth, WiFi etc. depending on your location and time is not available on the Verizon version of the phone. I know my way around phones, but I'm not too familiar with rooting in specific. Is there a way I can Flash another version of the v30 software onto this phone? I'd like to have full access to all of the LG settings most importantly really is the Smart settings option that I'm supposedly missing. Any experience, help, guidance would be greatly appreciated. I'd love to dive deeper into using the full capabilities of this phone if that's possible. This is my first post here by the way, thank you all for any help that you have for me!
With your settings menu set to list view, go to the Device section and Smart Settings is under there. If it's missing, let us know which version of the phone you have so we can have someone with that version look into it further. It's rather odd that it would be missing.
