[Q] Where is the LTE related files found in system? - AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin

I am working on a theory for my sgh-i337m, but I am still pretty new to all android programming.
Here is my situation:
I am working on modifying a custom ROM that is meant for the I9505 S4, I got it working pretty much flawlessly aside from some of the major reprogramming things(renaming device model etc.)
what I need is to find the location of the Modem/Driver for LTE. so far i have up to 4G and wifi working.

my bad, I figured it out, this question i asked is pretty much pointless, i already found the files before i asked this, just didn't realise it

Renaming the device model is fairly simple, out just need to edit the build.prop, towards the top you'll see multiple references to model number and what not...just change it to yours....you can also just compare the two different build.props for a better understanding always nice to see new people trying to dev, look forward to your progress

Thanks! I am actually talking with one of the members of the rom I'm working on, basically if I can get everything to work, without any problems of crashing/random reboots/etc. They may do those edits and touch ups and release it as an official device for their rom.

[Q] Dialer in US ROMs?

Has anyone actually tried copying out the dialer/phone app from an international ROM and putting it into a US ROM? I did a quick search of the dev and general Tab forums and haven't seen a mention of it.
Is the limitation for not making calls in the modem or kernel, or is it just the lack of the software?

I *think* it is just the lack of software.
Interesting. I may have to look into this, compare an international ROM to the stock AT&T one.
Are either of you actually reading these forums?
The AT&T Tab has already been hacked to make calls.
The TMo Tab can be made to make calls, but you'll lose 3G.

Dave

It's been tried. So has just flashing the modem. Neither worked.
Yeah I've seen those posts, I was just just wanting to see if there was any way to do it without having to flash another ROM onto my Tab. I'm guessing it's pretty deeply ingrained into the framework or something.
(Mainly wanted to ask because my quick search did not pull up results of retrofitting Phone capability into a "crippled" US ROM)
I dont know if this has been pointed out before but in my tmo tab when using root explorer and I look in system/app all the phone apps are already installed. They are just being blocked, is there a way to modify them to work?

The dialer is there and I think it is installed but is disabled somehow. Trying to bring it up just displays a message on the screen saying the dialer application is not supported on this device. I would be very interested in just modifying this ROM to re-enable that feature so flashing the EURO ROM isn't necessary. I am sure someone will figure it out before me but I am looking into it too. I am just so scared of doing stuff with this thing because for some reason it feels like uncharted territory and I am afraid of unknown consequences. Once the dialer is working a simple IMEI and serial number change will remove any restrictions on T-Mobile's end.

Simple IMEI change? Do you have the instructions?
Isn't that illegal to change imei?

Do you have an SPT box? You need the hardware this isn't a pure software solution.
http://www.sptbox.com/Products/Default.aspx
And it isn't cheap so I haven't decided whether or not I want it that bad. But I have been reading their forums and this product can in fact change the IMEI and serial number. It has been tested as sucessful on just about every GSM model of the TAB there is.
I just realized this is all way off topic. The OP is talking about enabling the dialer software and not changing the IMEI. Lets continue this in another thread.

New Xoom User

Hey, I just picked up my Xoom from Futureshop yesterday. I am in Canada and it is the WiFi only version.
I see there are many threads on Rooting and all that good stuff. My issue like always is there is too much information. I can never find what I want, or be 100% sure it's what I need.
So my first question is, is there a point to rooting the Xoom right now? Are there any useful and good ROMs for it yet? What other reason should I do it, I have rooted and installed ROMs on my Desire for ever now and the only benefit I see is the ROMs and a couple apps, yet I think I am missing a point lol
Second, for my North American (Canadian) WiFi only Xoom, which rooting steps and files do I need/follow? Thanks
Thirdly, excluding the Google applications and Games (because I already have them) what are some apps that support tablets currently? Also, what cool things are you doing with your Xoom?
Thanks.

This thread is definitely in the wrong section!
But I'll answer the first question:
The main reason I rooted was to overclock to 1.5 GHz. I also did it because I know that eventually I'll want to try out a custom ROM or run some other SU apps somewhere down the road. I also wanted USB host capabilities. As far as I know though, there aren't any custom ROMs yet, but there is a custom kernel, Tiamat. I haven't tried it yet, because I've been content with the stock OC kernel.
Oh crap, yea I didn't notice I was still in this section. Sorry, please move MOD.
Thanks for the reply. Overclocking eh? Will that destroy my CPU/device quicker or any other bad side effects?
And link to do that with my version?
Moved to general.
Generally, 1.5 GHz seems to be tolerated very well by the majority of XOOMs. If you notice random pauses, lockups, or restarts, tone it down a little bit.
You will likely notice a little additional battery drain, but as long as you're not on "performance" governor in SetCPU, you'll be fine for the most part.

Screenshot ER is a good reason Lets you take screenshots (no kidding!) without adb. I also have some other apps that need root like Root explorer.
EDIT: You might also want to ask: Why should I NOT root? Sometimes it helps to see both sides but I haven't found any disadvantage.
Ok, so I found this thread which seems to be my model.

One Click Root
The is pretty much the easies way to root your xoom. A one click method, and also unroot it back to stock if anything need to be done, like take it for repair to motorola or the upgrade for lite. It works for both wifi only and 3G. Just make sure you click the correct method for your kind of device.
There is also videos out there on youtube and google with it being done, that's how I got mine done. And more of a visual guy.
Here is the link from here on XDA, good luck. http://forum.xda-developers.com/showthread.php?t=1011196
Here is a link to the video I use, these guys have videos on both rooting and unrooting, enjoy fellow Xoom. http://theunlockr.com/2011/03/30/how-to-root-the-motorola-xoom-wifi-or-3g-one-click-method/
Well there we go! lol
Thanks a bunch.
I assume once I am rooted I just install that SetCPU app and play with it?
Best reason to root? Ad-blocking hosts file!
same thing here...wifi only in canada. I used one-click root ... click ok like 15 times and you're done!
one click rooting, nice! I'm new to all this rooting stuff........so that might just push me over the edge!
Other than ad blocking, not really. I haven't root'd mine.
Sent from my Captivate
Yea the part that gets me is the ability to unroot and put back to stock, just in case I need my warranty.
yeah the ability to unroot is the best thing since the xoom. Lol. Cuz you can always go back to original. Just a side note be very careful with that setCPU' it can be useful, and hurtful.the xoom is fast already, but. I mean as other have said, it is safe to an extend, but I would keep it that hight. One becauxe of battery life, and two because it could become an issue. I think if it was totally safe to clock that might, motorola would have been the one to do so, and would have put this device out the as having a 1.5Ghz processor. So just be careful, and as soon as you notice anything not right or normal, head for the door. Lol. (Go back to stock)
A-men.

I also bought my xoom at future shop. I used that link above to root my xoom and now im overclocking as well.
Do rooting enable the "Market Enabler" app?? and if the answer is yes, do this app fix the problem of the missing apps by hacking the market provider to [US] Verizon??????
It needs root and busybox. Basically, it lets you set your carrier to any carrier you like to fool the market.
It is often used by people who's countries don't provide market access.
Since I don't have a XOOM yet I can't vouch for its functionality on there but I don't see why it shouldn't work.

only 3g
I believe the above comment is correct. And as a side note I think the above app is only going to work with the 3G Xoom, not the Wifi only version. Because of the celluler radio. I have heard that both the wifi and 3g have a radio, because even the wifi version has a sim card slot, due to it being combine with the micro sd card. If this proof to be true, it could be a good deal for use with the wifi only. Cuz that means I pay $200 less. And if it is there, motorola will likely not make it active. But then once the codes are release, folk on XDA will make that dream a reality.
Don't count on that slot working on the wifi model. The important hardware like the radio will likely not he there.
The only reason the slot is there is because its combined with the SD slot and it would be costly and pointless for them to source an alternative socket just for the wifi model.

[Q] Making Cellular Calls On 3G Nexus 7 32gb?

Hi Guys!
I've just picked up a Nexus 7 32gb 3g and it's amazing to say the least. I can't believe for something just over £200 I have a full up to date android experience with premium hardware. Anyway what I was wondering was could I use this device to replace my recently broken Samsung Galaxy S1 (i9000). By which I mean make calls over 3g cellular. I want to pop in a contract sim and just use the minutes and texts of that and I was wondering whether it was possible?
I've done my research and apparently it's as simple as just copying over the default phone apk and it should work although I'm a bit skeptical as I've only seen one thread about. So what do I need to do to make cellular calls on the Nexus 7?
Regards,
Enya
P.S. I don't mind holding a 7" tablet to my face to make calls, I'd probably just use hands free anyway, and I don't mind rooting or flashing roms.
sorry for the off topic
but where did you get your 32gb 3g from - as ive only seen pc world, currys etc selling the wifi only for 200 pound...
would also like to know about the sim card and making calls / texts with the 3g model
thanks

N7+3g will sell in uk! Check it via proxy 62.233.100.46:80
I am also looking for an answer to this question, i can't find any answers, would you be able to try the phone apk and report back. I am not sure if you need rot access to do that.
Also interested, if only because the carrier that my SIM comes from occasionally requires me to make a call to their automated attendant when their online management tool isn't working.
Metaphorically speaking, Oh and yeah I'm probably going to try the phone.apk although I was wondering if anyone has had any experience or anything?
Oh and to put the phone.apk app back on I think you'll either need root access or ABD, but don't take my word for it, I'm no expert lol,
Uh-oh, just read that the N7 3G support won't be in AOSP for now because they weren't able to licence the GSM stack for AOSP
Wait, so you can't just push it into a system app i=in adb by extracting it from another phone that's running AOSP?

No idea. As of yet the only AOSP phone with 4.2 is the GNex (Nexus 4 is not in AOSP yet either due to the same licensing issue).
And unless devs find a clever workaround, N73G isn't going to get the same scope of ROMs as the wi-fi version until they sort out the licensing.
Any results yet?
enya123101, did you try the phone.apk ? I'm really eager to find out if the NExus 7 can make phone calls and I can't find answers anywhere
please let us know
Please don't keep us in suspense. This data is what I need to determine between the Nexus 7 or the 10. I find it odd that this question is not being ask more on the net. http://forum.xda-developers.com/showthread.php?t=1958686 is the only other thread really that's asking this question and not just some random mentioning of it in a sea of Nexus 7 threads out there.
Thanks again for being the guinea pig.
you can not just push phone.apk in fact your device ALREADY has phone.APK and if you try to push it then you will receive the message "you are replacing a system app.
the reason you cant USE or SEE it is because of the way our framework.res is compiled and it is not set as a phone device it is set as tablet among other settings that are different as well.
its not that easy but hopefully once its out in full force then developers will figure out a way perhaps with custom roms that allow it.
any info yet
like the others real interested to see some results

[Q] Is safestrap even worth using? Can I gain extra abilities not in stock?

Hello, just was wondering yet again about this whole safestrap, since I am stuck on 4.3 MK2 right now. I mean I see that its running off /sdcard and that I can choose the /data partition, however I am lacking some info here.
Stock rom, how much is that /data partition? Do the apps I have already on my stock rom carry over or would they need to be all reinstalled, which would take up more space?
I do have a 64GB External card in my phone, can that be used any?
Finally for now.. could I gain abilities that my stock rom seems to lack? Cifs support, Better PPP support? Wifi tethering that I can change the macid on?
Almost half tempted at this point to offer a commission to get me on the right path.. had this phone for a year now and its the ONLY android in my entire xda history.. that I havent modded really yet other then a simple root. =( Shouldve never let the TMO S3 out of my hands.. least that one I had everything the way I needed it.. cept LTE support. Which is why I even went to this phone.

I mean if you cant touch the kernel, then I am not sure that extra abilities, like network file mapping, or so could be even added?

The abilities you get out of Safestrap ROMs are only on the system side. Technically on the 4.3 kernel we have a way to load unsigned modules, but currently that's only being used to aid in the development of a kexec module to let us load custom kernels. But other than that, the only thing you gain is system mods like changed/themed UI and extra toggles and settings that don't require kernel changes. If you use the KitKat Magic Toolkit you can actually get a mostly working Google Edition ROM, but that's by preference and there's a few things not working with it still.
Thanks for the info! So its kinda as I thought.. no real point in it, since it doesnt give the ability to be a power user system... Main one I really need is cifs.ko for the network file share ability to access my folders for one.. then wouldnt mind being able to have my wifi tethering back where I can assign the macid.
Wonder if the galaxy s5 is also hard to work with. =/
Just wonder so much why people would prefer safestrap unless they just like the ability to boot into an OS theme of choice?

Please include "T-Mobile version compatible"

When developers on XDA create mods, ROMs, etc for the 6t, I'd like to request that they post whether or not it is T-Mobile compatible o, or if they don't know, just post that. And, if someone does find out after the original post whether it's compatible or not, that they add that to the original post.
I know these developers do a lot but this would be helpful to a lot of us who got the T-Mobile version. Thanks.
The answer is yes. It's T-Mobile compatible.
There's no real difference between the devices. If it works on one, it's going to work on the other.
sorry for posting this here, but for some reason, I cant add a new question/topic..
Can you get the home screen to rotate when using the stock launcher on the Tmobile version?
I assume I could with Nova launcher, but I am trying to get used to the built in one..
thanks so much!

That's not a hundred percent accurate. For example the pixel camera that was ported over had to be changed to accommodate the T-Mobile version. There are some differences. As someone who's not developer I don't know exactly what those are but I do know that there are some differences and there have to be some modifications on some things.

One thing had to be changed. It's because he has a compatibility list built into it based on the device name in the build.prop. He could have checked against a different build string and there would have been no issues. He only does this to cut down on complaints of devices he's not supporting. It was a self imposed limit that was quickly remedied on a device that was a few days old. This is limited to this app only and is not the norm at all. The only other time you'll see something like this is a mod to make the international launcher use Google feed, which the TMobile version already has. Or a mod to bring some feature from the international version to the TMobile version. In that case there's no need to mention it, it's obvious. No need to add a feature/app/mod you already have. And the person who made that will definitely mention that they're bringing the feature to the T-Mobile version.
Edit: also these mods will be few and far between since the way to install those mods will require an unlocked bootloader/root, and at that point, someone will most likely be running the international rom just to stay more current/more features.
Mods will work the same. ROMs will work the same. Kernels will work the same. Magisk mods will work the same. Apps will work the same. The devices are the same.
Your request would make sense if we shared a forum with the OP6. The devices share the same device tree, they are extremely similar, but there are minor differences between the devices that might make a handful of things work on one but not the other.
