[sugestion]-simple way to change rom. - Legend Q&A, Help & Troubleshooting

at my own experience, htc phones are really hard to root, especially the legend, scince it's a mid-end device, and the effort put into hacking it isn't even half of the effort put into high-end devices such as sensation or dhd.
i came across a simple idea that may able to hack most android phones, not only the legend, in a relatively easy way, but i need expert help to make the concept functional.
part one: softroot.
the "universal androot" worked fine for a softroot, and it gave me full access to all system files and folders.
second part: finding and changing the update domain.
here is the first time i need help.
i need someone to tell me whitch file contains the update domain address, so it can be changed to a personal server address in the network we work on, so that the phone serches for a new rom in a server we decide.
third part:server preparation.
i guess this is the most difficult part, scince i first have to find out what protocol is used to make OTA updates and find a server program that works with android.
then it's simply the matter of transferring the rom file (.ruu) to the server.
the idea is still a concept, scince i am not an android developer nor windows developer, but i guess that the idea is posible and can help people change roms in a safer and faster way.
if anyone can make the idea usable, i would really like to know about it.

Dont want to spoil your enthusiasm but something like this already exist.
Its called ROM Manager...

[Q] Aria requirements.

I am looking for a Smartphone with a particular form factor, the form factor is shared by the P3600, the Aria & the HD Mini. I have the 3600 but it is time to upgrade
I’ll be honest I’d rather get a HD Mini than an Aria, but I want to stick with Tel$tra and Next G is on 850 Mhtz,
So Aria it is.
Now looking at the ups and downs of this proposition it looks like it will do everything I want out of the box (Give or take a bit) the only concern is the ability to run apps from the SD which doesn’t appear to be available until upgrading to 2.2.
If I want the phone unlocked and free to do as I say, I obviously can’t go downloading a carrier specific Rom, so need either a factory default or Home baked number.
So… What Android 2.2 ROM is available that is as close to the Unlocked factory default as possible? Or can you download the Unlocked Factory Default from HTC direct (I have tried and failed)
You're looking for gene Poole's liberated 2.2.2 or attn1 fr008.

You want Gene Poole's Liberated 2.2.2
Also, how and where are you getting your phone?
Most of us (it seems) in this forum got our phones when they were running 2.1 and we were able to easily root them with unrevoked. People who have gotten the Gratia or warranty replacements recently with the official 2.2 system in place have not been able to root.

Thanks for that mtnlion. I thought this was my last hurdle but then I considered the implications of syncing outlook contacts and calendars… It appears that you need a third part application to do that. FFS why can’t someone port WM6.5 to the Aria HW? It would make life so much easier.
Is it time for me to start learning to cook ROMs?
Thanks for the update stoneship. So it isn’t all as easy as it seems on the surface. SOD…
Maybe I just have to cross my fingers and hope that HTC keeps supporting the small form factor and wait for there next round of releases, and hope something fits.
I haven't used it in quite awhile but I'm pretty sure the HTC sync software will sync outlook and calendar when you plug in your phone.and there are apps on the market also.

Thanks again mtnlion, but this still leaves me with the issue highlighted by stone ship that some systems won’t let you root break them and put on non official ROM images. The Aria as a solution is so close I can taste it… But I am just not confident it is going to be without issues.
Ahhh Screw it… I have bought one… How much trouble can it be???
Well... after rereading your post it seems that you may not be aware of this.
The phone you purchased will most likely (if new) come with software preinstalled from the factory that will prohibit you from rooting it via software methods.
You will need to send the phone to someone else to downgrade it for you. Then you can root it and install the software above.
Hope that made sense, I'm running on fumes... :-/

Cross your fingers that you got one with 2.1 on it so you can root it easily. If not I can point you to someone who can s-off it for you.
The Aria is a great little phone and once you get things sorted out I think you will find you can do what you need with it. Syncing outlook contacts and calendars should not be an issue either through activesync or HTC sync regardless of official or cooked rom.
You say Active sync or HTC sync??? Does that mean that M$ Active sync can sync with an Android device? That would be weird.
The device is advertised as unlocked and 2.1 As long as it is unlocked then I am good even if it is 2.2 I don’t expect to need it rooted in the immediate term, though I do expect I am going to have to hack around a little to get the Audio on my Cardo Scala headset sorted (it doesn’t support A2DP) so I may be eating those words in short order.
Though in the words of the great tosser Jeremy Clarkson… “How Hard can it be?”
Seeing I am asking these questions I may as well outline the Bluetooth issue I have and see if any one can shed any light on the Android solution.
As I said in my previous post my Bluetooth headset doesn’t support A2DP, so to get music playing on it (or get GPS spoken directions) I need to perform a couple of hacks
The first one is to combine the stereo channels so on my Windows mobile I do this by applying the following to the registry.
[HKEY_LOCAL_MACHINE\Software\Microsoft\Bluetooth\A2DP\Settings]
"UseJointStereo"=dword:00000001
The second (And more important) is to change the Bluetooth channel behavior which is done by making the voice command attribute do nothing (remove the path of the executable) and keeping the channel open for an indefinite amount of time (VoiceCmdDuration being a large number)
[HKEY_LOCAL_MACHINE\SOFTWARE\OEM\VoiceCommand]
"LaunchApEnable"=dWord:1
"VoiceCmdDuration"=dWord:15180
So… In Android, what files do I need to tweak, and how do I need to tweak them to achieve the same results?
Thanks
Well I now have my aria in my greasy little hands, and for better or worse… It has 2.2 loaded.
Starting to sort my way through the maze of setup now…
Patience.

The Limitations of Android are really annoying. (Unrooted)
I can’t Leave the device Synchronizing and also copy files back and forth (I Can in WM5)
I can’t copy files directly to the device only to the SD Card (I Can in WM5)
I can’t access the SD card from the device while I am accessing it from the PC (I Can in WM5)
I can’t edit configuration files to alter how it interacts with things such as Bluetooth (I Can in WM5)
I can’t store resources such as ringtones on the device, only on the SD card (I Can in WM5)
I can’t control the phone from my desktop computer such as MyMobiler (I Can in WM5)
And these are just the limitations I have found in 3 days when comparing it to a 6 year old Operating system.
And because it came pre installed with 2.2 I can’t root it…
It really appears that if it isn’t rooted it is pretty F#$ked.
Android is not really designed to be synchronized over USB. Yes, you can do it, and HTC makes a program for it specifically, but I suggest abandoning that habit and getting used to wireless syncing instead. The only reason I ever connect my phone to a computer is to copy a file, and even then I sometimes choose to do it with Dropbox instead, or send the link to the phone through ChromeToPhone.
Even if you don't want to use Google Calendar/Contacts as your primary calendar/contacts manager, you should be able to set up Outlook on your computer to synchronize with them. I don't personally use Outlook so I can't say what the best method for doing this is, but perhaps someone else can chime in with a suggestion.
As for the SD card, I don't think there is really any significant disadvantage to storing files on the SD card. Assuming you just leave your SD card in the phone, what's the difference? Some Android phones do have internal memory you can use for copying files to though.
As for the bluetooth issue, yes, that sucks. Good luck finding a solution for that if one exists.
Well An Update…
My Blutooth issues are managed by this app
https://market.android.com/details?id=com.bedoig.BTmono_Donate&feature=search_result
It is O.K. But does have a nasty habit of rebooting the device if you don’t shut it down properly before disconnecting the bluetooth connection.
It still doesn’t allow me to initiate actions from the headset other than picking up calls, but at the end of the day this is all I require.
After my torrent of negatives I have found a few starters for what Android is doing better…
When you mount the SD card to the computer it is fully available, you can read & edit files not just copy to and from (I Can’t in WM5)
Once you throw a file manager on the device it browses UNC paths well
Though It does appear I am getting some really weird $hit happening with my Outlook calendars.
And I have noted that I can’t have different screen timeout behavior dependent on weather it is plugged in or not.
If I could have the best of WM, and the best of Droid, I would be a happy little camper.

[Q] Problems with developing a custom GS2 rom for medicinal purposes.

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.

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.

[Q] Why is gps.conf not changable?

I live in europe, I have had several android devices (from most of the different Manufacturers).
On almost every phone I've had problems with slow/bad gps locks.. the fix, almost every time editing gps.conf to put in the
european ntp servers... this also meant rooting the phone...
Most of the time I actually don't care about rooting, I'm happy with the stock rom as is...
WHY do we have to root the devices to get them to work like they should?
I mean during first bootup of the phone when locales are chosen, why can't it set the correct ntp servers to where the device is going
to be used?
Am I totally stupid and missing something or are the manufacturers (or Android developers (Google)) stupid?
Anybody have any insight on this, or is it just going to be one of life's big mysteries?

I used ES File Viewer. Go into the settings and choose Root Settings and check everything. I still wasn't able to save my changes so I copied gps.conf to another folder, made my changes and saved it. Then I copied my edited file back to the etc folder. It allowed me to replace the original file.
It hasn't fixed my GPS problem but at least I got that part done.
Good Luck!

Issues with Cloning Android to Identical Devices

Hey guys,
I have an issue I'm facing at the moment. I have purchased 3 Samsung Galaxy Nexus devices for my family, and one for myself. I wanted to setup all our devices for them and pre-install essential apps for them, and lay it out in a way which makes each device identical so that my family (which is new to Android) can all get the same easy experience from their devices, rather than everyone getting a different LG/Samsung/HTC device and having to deal with differences in skins every time someone phones me with a question about their device.
Here is what I have done:
1. Unlocked bootloader, root, installed CM10.1.2 + gapps onto my own personal device. Clean install, wiped everything.
2. Setup android with a temporary Gmail account, installed about 20 apps, setup the homescreen, changed a few settings for simplicity, change wallpapers, etc.
3. Once I was satisfied, I removed the google account, rebooted to recovery (CWM 6.0.3.2) and made a Nandroid backup which was later copied to my home server.
4. Unlocked Bootloader, rooted and installed CM10.1.2 + gapps on all the other devices, booted the device then transferred the Nandroid backup from my home server to each of these other three devices. Restore the backup, reboot, all seems fine so I setup new individual google accounts, and away I went. Everything works fine, at least so it seems.
Now the issue is that I'm having came a day or two after I got everything setup on each device. At the moment I'm having serious issues with the Google Play Store and Push Notifications. Almost all devices intermittently have issues with this. The play store issue I'm getting is [RPC:S-5:AEC-0], and prevents me from downloading or updating apps. Push notifications is not working either. For example, Google hangouts notifications don't notify me of messages on devices intermittently unless I manually check the app. Same goes with facebook and snapchat notifications. Very annoying. Tried all sorts of fixes such as removing the Google account, rebooting and adding it again, but no luck.
It seems like there is some sort of conflict with each device, but I don't understand why. I changed the Android ID on each device hoping that would help, but still no luck. If anyone could offer an explanation why this issue is occurring I would love to hear it!
Cheers.
Edit: Tried making a titanium backup of one device and moved it to a rooted Galaxy S2 running CM10.1 nightlies, and no such issue. Also, updated one nexus device to the latest nightly, still no fix. Hopefully this information will help someone be able to point out the problem somewhere.
Okay, so I've been playing with a couple of these devices today, and by removing a google account, rebooting the device and then adding the google account again, it makes the play store work on that device, but breaks functionality on the other devices. Would someone with a low-level understanding of Android care to explain why this is?
I'm going to try doing a factory reset on one of these Nexus devices and restore a Titanium Backup and see if that helps, unless anyone has any suggestions?
The different accounts are linked to the play store separately, you are best off to just downloaded each app and set up each phone with its own gmail account. I know it sounds time consuming but it would take less time than you've been spending already.
As you learn more about android there are lots of ways of doing almost exactly what you want here, but learning right now will take less time and effort than downloading 20 apps to three different phones

Thanks for the advice, but at the same time I'm using my family as guinea pigs to test whether it's possible to clone devices like this, as I'm in charge of the IT department at our organisation and I suggested it may be possible to deploy a large number of identical rooted android devices through the organisation (probably around 30-40 devices to start with). At this stage though, there seems to be some issues with doing this. Would you be able to point me in the direction of how I could clone Android to several devices, or at least deploy an identical setup to several devices? Perhaps I'll need to customize my own ROM based on Cyanogenmod? Chances are I'll be having to support different hardware as well. This may include the Galaxy Nexus, Nexus 4, Xperia Z and the LG Optimus 4X HD.
Well the absolute best way, in my opinion, would be to create your own ROM.
And by this I don't mean you need to learn how to port or build from source (at least not at first) just some simple zipkanging will do for something like this
Take the ROM.zip, open it, take out apps and such you don't want, add it the ones you do, rezip and sign
Now flash this to each phone and they will all have the same ROM and can just add their Google account.
Now if you want to have certain settings or the system ui look different than this you will need to learn how to decompile some apks and edit xml files, but start slow, do what is easy and what you can't figure out let me know and I'll try to help

Thought this might be the case.
Is it relatively simple to copy the changes I make to one ROM (eg for a Galaxy Nexus) for another ROM (eg. for a Nexus 4)? Is there some sort of Android virtual machine I can test or build this in?
Not simple at all, I was referring to multiple phones of the same type. Its easy to create identical ROMs to be flashed between 30 n4s or 30 genexs, but to create the same identical ROM to work in both types of phones would require source builds matched to each device tree
Which if you know little about android, java, c++ etc, then you have a real long journey ahead of you.
If you want to have an identical ROM (based off one already in existence) be flashed to 30 identical phones this is relatively easy depending on what all you want
Like I said, start small, learn what's easily obtained, then try for something bigger

The idea was to use CM10.1 as a base and simply add in some apps + app data and change some settings. Setting up the homescreen in a certain way would be part of that. The Galaxy Nexus, Nexus 4, Xperia Z, and LG Optimus 4X HD all support CM10.1 stable.
If I setup a device the way I want it, would it be possible to extract some of these custom configurations from the live device to a flashable ROM?
Just because there is the same ROM for each phone doesn't mean they are exact, but in your case probably good enough. But the change you would make would be to each individual ROM (on computer not on phone) and then flashed these new versions of your ROM to each phone.
You can not make changes to your phone when running the os and extract these changes and flash them to another phone easily, near impossible to do it to a different phone make
Like I have been saying, take a ROM, open it up on PC, change what you need, flash to phone. The simpler the changes the easier it is to do. This will have to be done on a case by case basis if you are doing it to multiple types of phones
Now if you give me a list of what you want to change exactly there may be a few things you can do on your phone but in reality this is the harder way, doing all the work on PC is the easier way
Sent from my Nexus 4 using xda premium
Yes, I understand that. I think what I'll have to do is record the changes I make to one ROM in a changelog of some sort, and then simply recreate these changes manually to other ROMs. Through the PC of course.

Well for example, here are the outdated and rough changes I need to make to the settings (this is just a note of the changes in the settingsof the ROM to make it run way I wanted on the device). Attached it as a PDF as I couldn't copy the formatting.
Most of that should be doable by decompiling systemui.apk and settings.apk, somewhat time consuming and depending on your experience a steep learning curve, but should be able to do it

Learning about Android and other things. Is it possible to open up developer options and remotely root or write files to someone's phone? I mean not just apps but the bootloader and entire OS of the phone?

I don't think it's possible to root the phone wirelessly since it need a reboot. If you're talking about privilege escalation hacks, that's a whole other planet, that I'm not qualified to help in (and would not want to since this technique is misused very often)
Well this is happening with me I've started noticing files from 1969 and I know Android was invented in 1969 least of all system files so I dove a little deeper and I'm in need some help. I ain't the cleanest person in the world but I'm not hacking anybody I did download programs to learn more about file systems and programming so I could customize my own devices. This is twice this is happened now in the past 2 years. I'll just say anything this is just a hobby of mine to take and learn my devices and computers and the games for my kid but guys like this or just making it where I don't even want to have a computer or a phone. It says my phone is rooted and it also says that abd is used on it. I downloaded a toolbox and started looking around and system processes that I tried to disable let's just say Facebook I have uninstalled it over seven times yet it keeps appearing is it because they are installed factory version and he's using Android auto which is another dumb program I never use and I have disabled it but somehow it always is enabled with all the permissions enabled.
By the way I have many of these files saved on external cards and I have logs on this. and this is not just one device its multiple devices in my household and I don't know why this guy chose me because I don't have anything of value he can take in real life that's just being honest
