Found the bug in mms

well after talkin to htc and verizon for a few hours , i found out y the mms messeges werent being sent,, its cuz when we ported the sprint roms it changed the MMSC URL
to sprintpcsmms it should be http://mms.vtext.com/servlets/mms"
so its tryin to send them through sprint
the problem is tryin to edit it , but im sure there are people here who can figure it out
we need the url for verizon http://mms.vtext.com/servlets/mms
if u have stock mms apk u can see this in settings /connections
im wondering if we take out the apn from the rom we are porting put ours in its place ,resign the rom , then port if it will work, has anyone tried this ?
sorry just my two cent on this

already tried it, but heres the info on how to change it. i couldnt tell if it actually worked, the only people i waS ABLE TO test with was the same people who i had no issues with mms
Code:
adb shell
cd /data/data/com*telephony/databases
sqlite3 telephony.db
update carriers set
mmsc='http://mms.sprintpcs.com?X-MDN=YOUR11DIGITNUMBER'
<http://mms.vtext.com/serverlets/mms?X-MDN=YOUR11DIGITNUMBER%27> where

ok my bad i thought they told me something new

nah, its been tried by me a few times, but like i said, feel free to try it. maybe your results will be different

I have tried to send a mms on CyanogenEris and ELB 2.5 Cyanogen, both do not work. I just loaded up ZenEXP-v7 and tried sending one, worked fine. But it has the "HTC" message app not the AOSP one. I think we need to find out what the diffences are.

That connections info is EXACTLY what the APN trick fixes.
It's how I got the first Eris to send a mms msg on Cricket, if you do the apn restore of a verizon ROM, that gets fixed.

i know how to patch it ,, i used mmszap , i was lookin for a way to fix it and make it stick in a rom

change the apns-conf.xml under settings/etc

The fix above fixes sprint sense ROMs.
AOSP roms such as ELB need a source code change, not a APN change. Possibly permissions. I suggest we look at koush's work on the Moto Droid's port of CE for clues.

Ok if I am going to try to use MMSZap what do I need to fill in besides the MMSC url

unlocked and upgraded to 4.5.91 NO DATA :(

Hello guys,
I have a sim unlocked, bootloader unlocked, 4.5.91 gingerbread, AT&T atrix 4g on Fido network in Canada.
I made the apns using the same apns from when i was using .81 but I can not seem to connect via 3g/2g/gprs. The only way to use the internet is via WIFI.
What do you think is the problem?

try a reboot...

I'v rebooted at least 10 times now

did you make a backup?
You can go into your Mobile Settings and do a 'reset to defaults'.. otherwise, if you made a backup of you system file, you can copy 'apns-config.xml' from /System/etc to the same directory on you phone...
I had the same issue, I just did the 'reset to defaults' and got my apns back.. but going to copy my previous apns-config.xml file cus that had custom apns..
hope that helps..

I alread have tried reseting to default and adding the APN's again.
as far as system back ups, I dont have one

You can find the apn settings online, i would create a new apn and put those settings you find in. I had issues with mine, and when I did that, it fixed my problems. I put a link below that has the apn settings.
androidforums.com/htc-inspire-4g/276917-inspire-4g-apn-settings.html
Edit: sorry, I didn't realize you weren't using att...but same idea, just manually set up your apn network

Also, you could have the wrong mobile radio installed. I know that they are set to pick up certain frequencies and that radio might not work on fido.

Hmm.. that is weird, maybe you can pull the apns-config.xml from one of the Bell ROMS or from one of the P-ROMs floating around in Dev section to replace what you have now for APNs... just adb it to /System/etc/ , then reboot and go back into your APN settings to see if doing another reset to defaults will work if they don't show up after the reboot..

How do I check what radio version I have installed?
as far as icons are concerned, I get H+ icon

Go to about phone in settings and its under baseband version. I had a similar but not same problem, which was solved by resetting the apns as that seemed not to work in your case. I would try to flash a new radio.

Ah.
Here is a new radio:

I have the same problems after 2 day of 4.5.91 update I loss the complete data conection, any apn that I usualy use work, I dont have any idea to solver the problems, work only for wifi, I use a diferent radios and is not solver the problem. I have a atrix AT&T root + bl unlock + 4.5.91 + 30p radio.

Here's a CWM zip file of ton of APNs. Just install and go to your APN list and reset to default. If it's an APN issue. As far as radio, not sure which you need for your area. http://api.viglink.com/api/click?format=go&drKey=1359&loc=http%3A%2F%2Fforum.xda-developers.com%2Fshowthread.php%3Ft%3D1189497&v=1&libid=1313370618834&out=http%3A%2F%2Fwww.multiupload.com%2FXW7FT9N3Z4&ref=http%3A%2F%2Fforum.xda-developers.com%2Fforumdisplay.php%3Ff%3D997&title=%5BROM%5D%20CHERRY%CF%80%20%26%20%CF%80CRUST%20v0.7%20%5BAT%26T%5D%20%5BINTL%5D%20%5BGB%5D%20%5BD3%20Camera%20w%2F%201080p%5D%20-%20xda-developers&txt=%3CFONT%20size%3D5%3ELarger%20APN%20List%20from%20v0.3%3C%2FFONT%3E&jsonp=vglnk_jsonp_13133705901661

Just a (possibly) stupid question, but after you reset to default and input your apn settings, are you clicking on it so that it is highlighted in green?
If all of that doesn't work, I would try re-flashing whichever rom you are using through CWM recovery and see what happens.

No Internet connectivity on Android Revolution ROM

Since flashing Android Revolution yesterday I have been unable to connect to the Internet unless I use wifi.
I have a 3gb data allowance and I'm no where near that limit.
There is no G, 3G, or H symbol, just the signal symbol

Hi,
here some ideas maybe some will help you.
1. Did you check the md5 of the rom?
2. Have you enbled the Mobile data?
3. Did you have set the apn for your provider?
(Menu-Settings-Wireless/Networks-Mobile Data-Accespoints)(Sorry if the names are not 100% right i use German version)
4. Maybe set Network mode on GSM/WCDMA Auto?
5. Maybe some Radio or Kernel Problem?
If nothing helped try posting again in ARHD Thread
Greetings

same problem

Are you using the recommended radio?

This is most likely the problem.
"3. Did you have set the apn for your provider?
(Menu-Settings-Wireless/Networks-Mobile Data-Accespoints)"
Mobile data settings are not stored on "sim" like "sms" settings. You need to manual input them each time you flash. You should find these settings on your providers website on the support page. Once you find them copy/paste/save for future reference. It only takes a few seconds to put them back in.
If you use Titanium Backup these settings are saved in system data backup for future restore, but its recommended only to restore apps+data when flashing a new rom to avoid conflicts.

I agree with FurryCup. APN is responsible for mobile devices to connect to the Internet. To check or set up your APN, you should go to Menu>Settings>Wireless & Networks>Mobile Networks>Access Point Names. You can either add a new APN or edit an existing. Just make sure you have the correct APN settings.

I agree with FurryCup.
Also for future use, you can use APN Backup & Restore / Android Market to save your original APN to your sd card (as an xml file).
Also keep APN Backup & Restore apk on your sd card. (Source)
Every time you flash a new rom - install APN Backup & Restore (from the apk on the sd card), delete the APNs which came with the new rom, restore the original APN which you saved - from your sd card.
Then choose that APN in the phone settings as FurryCup mentions.
Then you can access the correct network as your carrier provides with your phone and contract.
Note: APN Backup & Restore doesn't work with Ice Cream Sandwich.

not sure if its any help to you, BUT... when i installed the rom (my first ever rom) i couldnt manage to install the radio that i was ment to, and everything works fine.
so not sure if the radio you've installed has anything to do with it.

It was the APN, the ROM had automatically set Virgin APN as default when I'm actually on T-Mobile, so I selected the right one and it was working fine.
My phone usually automatically knows my APN details and sets them as default, but it didn't with ARHD for some reason.
Thanks for the replies

When you first flash the rom it asks for the carrier to use. Maybe you hit the wrong option?

No I definitely chose T-Mobile. The APN details for both T-Mobile and Virgin were there, but Virgin was selected as default.

SM-G900V 6.0.1 Custom Rom verizon mobile data not working, custom APNs disappear

Searching the forums i've found scattered reports of similar issues but only one possible solution. The fix seemed to work for a few minutes but now can no longer get to work.
Unlocked bootloader and installed vincom's superlite 6.0.1 rom from https://forum.xda-developers.com/ga...-superlite-mini-mm-v1-0-361mb-g900w8-t3497158. Also flashed the 6.0.1 QL1_MODEM_NON-HLOS and QL1_MODEM from https://forum.xda-developers.com/verizon-galaxy-s5/development/modem-modems-t3154630. Everything seems to work except mobile data. Phone calls can be placed and received with no problem. Text messages can be received but not sent.
Viewed the Access Point Names (cannot be accessed through the normal settings menu but accessible using the Change Apn app) and can see a variety of Verizon APNs with possibly outdated information (MCC 311 MNC 480)? Attempted to create a new APN using instructions at https://forum.xda-developers.com/showpost.php?p=61262681&postcount=3 and info at https://bestmvno.com/apn-settings/verizon-wireless-apn-settings/ While the APN disappeared, as do any of the other options when the MCC and MNC is changed, the new settings still show up in /data/data/com.android.settings/shared_prefs/com.android.settings_preferences.xml (as mentioned in https://android.stackexchange.com/qu...ved-in-android)
The first time I created the new APN the LTE icon showed up and i was able to view websites using mobile data and receive text messages. 10 minutes later tried to send a text message and it failed, then noticed that no mobile data was working again. Have tried repeating the previous steps, but still no luck.
Any help is greatly appreciated

There's a few things to try to get the APN populated because the APN's are, typically, updated via the Verizon Network.
1) Sometimes if you Toggle the "Preferred network type to/from Global to LTE and restart the device, this sometimes will help with the APN's to get refreshed/updated.
2) I've got Net10 on my G900V and I have had to perform a Chat Session with the Net10 Support people (because I've had better luck with chat versus calling. That's your choice) and asked them if they can perform a Network Refresh for my device on the Verizon Towers. They may ask me to check one or two things that I usually respond with it looks good to get them to do the Network Refresh.
I hope one of these works for you and that I had explained this okay via text.
Good Luck!

The ability to access that specific setting is dependent upon the Firmware ROM installed. The Firmware would have to be developed with this feature.
This should be asked within the "Vincom's Superlite ROM" Thread.
Maybe they have this specific setting located elsewhere on your device...

Thanks, as far as I understand it's a debloated version of the official Verizon 6.0.1 rom, i believe the same settings are hidden on the official version of the rom too. thanks again

I'm not 100% sure regarding the Stock Firmware because I haven't had it on my G900V in quite a long time.
I've got 2 of them and 1 Has CyanogenMod and the other has LineageOS.
If memory serves me correctly (with a lost mind... LOL!) I believe that you may be able to access these options using one of the specific Dialer Codes but, I can't remember what any of them are.
As I had stated before, your best bet is to obtain some member guidance within the Firmware thread your using.
I wish you the best of luck!

Another thing to try is find the boot image from the original rom and flash that. I do believe that requires a custom recovery like twrp. Is their a specific reason youre not using something like LineageOS or Candy Rom? They both have Android Oreo 8.1 versions available.

Xfinity Mobile Data Not Working

Hi,
Is anyone else having a problem with Xfinity Mobile data? I can make phone calls, but I can't get any data connection. This was a phone I bought from Sprint, and due to their messed up unlock system, it got relocked, so I manually unlocked it by using this method: https://forum.xda-developers.com/showpost.php?p=75994498&postcount=360
After that, the phone got unlocked successfully. It accepted a TMO sim, and I was able to update to newer firmware. Today, I decided to put it on my Xfinity Mobile line, and I just can't make data work. Any help would be appreciated.
Thank you,

OK. I think I narrowed down the problem. APN setting has VZWINTERNET. It's supposed to be COMCAST.RSLR.VZWENTP based on what I read on the internet. The problem is, I can't edit or add a new APN. I saw someone else talking about this APN setting problem, and his was resolved with the April security patch https://forums.androidcentral.com/e...cant-add-edit-apn-all-sudden-lost-4g-lte.html
I have that security patch already installed, but my problem persists. I can't change APN. Any help would be appreciated.

It's possible Xfinity locks the APN settings or that it has something to do with yours being the Sprint version. I would power the phone down and remove the SIM. Power the phone on with no SIM card and when you are booted up go into settings and reset the network settings. Power down again and insert your Xfinity SIM. That should ensure that the new SIM populates all the network settings.

Thank you for replying. That did not work. I don't think it's Xfinity. The problem is that APN gets locked to VZW instead of Xfinity's APN, which is why data doesn't work. I can put a TMO sim card in it and it works fine, so I don't know that there is something wrong with the phone itself. If you have any other suggestions, I would appreciate it. I'm desperate to get this working.

In a Reddit thread, a user says you need to disable Enhanced LTE:
Under Settings > More > Cellular Networks, disable "Enhanced 4G LTE Mode" and set "System select" to "Automatic"
Haven't tried it myself, but I'm thinking of switching to XM and would like to know how this works out for you.

Get your original Xfinity phone factory reset the original Xfinity phone put your Sim in go through activation. This should work for you this also fixes volte on Xfinity If your volte ever gets deactivated. Anyway from what has happened to my other phones sometimes the apn can get changed on the Sim and got carried over somehow. Resetting the original Xfinity phone will bring the Sim settings back to the Sim card thus fixing your apn settings.
(Another way is to use another phone to edit the apn settings)
I also have Xfinity mobile and it's working fine. Just sometimes my apn gets uncheck and I don't know why
If you messed with bands.
Also make sure you go and download hidden settings from the playstore if you messed with your bands and selected American bands you need to select automatic bands if you messed with radio information page settings.
I messed with bands and it caused phone calls to not work.
---------- Post added at 10:08 AM ---------- Previous post was at 09:31 AM ----------
The Sim saves apn settings and I did notice the first time using this essential phone I had 2 options in the apn and I read carefully which one to select. It may have saved the incorrect information to the Sim. I did this once on a Moto phone and I thought if I put Verizon apns instead of Comcasts I could get better speeds. But I caused my data to stop working. I reset the Moto phone and u still had the problems. I looked for the apn for Comcast couldn't find it. Then I thought of either editing the apn using another phone or using the original Xfinity phone. But it does get saved for sure. I ran into this issue before and I'm pretty sure this will resolve the problems.

Yes. I manually sideloaded Beta Oreo build, even though my phone already had the official OTA Oreo on it. That fixed the connection issue altogether.

Wow. Glad to hear your issue is resolved. Who would ever think of going back to a beta build from an official build to fix a connection issue! I may try Xfinity mobile in the near future. Thank you.

Yea, it was just a desperate move lol. Glad it'll be helpful for others.

I had the worst time making the XFinity mobile work on Android Pie with the October patches in place and finally got it working. Basically, there was no way to edit the APN configuration even with root on the device via actual Android. What I did to fix this was the following...
-Followed the rooting procedure to get TWRP and Fastboot installed
-I then used "Termux" to copy the APN points configuration file to a writable location. In my case I copied the file from "\system\etc\apns-conf.xml" to a "\sdcard\Download". Keep a copy of the original file.
-I then simply copied the file over to my computer and opened it in NotePad++. I did a search for the following string in single quotes: 'carrier="Verizon"\n mcc="311" '
-This should pull up 5 results in the search and you should confirm that each of the lines has the mnc value set to 480, 'mnc="480"'. On each of the sections that came up, I switched the following variables as shown below...
apn="COMCAST.RSLR.VZWENTP"
authtype="0"
protocol="IP"
roaming_protocol="IP"
-Once you have edited the file, copy it to a writable location on the device, like "/sdcard/Download".
-This then requires rebooting into recovery mode with TWRP and you will need to make sure you have encryption and a PIN disabled on your device to make sure you have full access to the device file system.
-Within the main TWRP page, select "Mount" and you will need to have the "System" and "Data" partitions selected.
-Return to the main page and select "Advanced" and then "File Manager".
-Next, locate the original apns-conf.xml that you copied earlier. It should show up as being in "/system/system/apns-conf.xml". Click on that file, and select "chmod 755".
-Next, navigate to where you have the edited apn file located. Copy that file over to replace the apns configuration file at "/system/system/apns-conf.xml". Just make sure you have a backup of that original file before replacing it.
-Finally, reboot your phone into the OS and you should magically have Xfinity mobile working.
This took a lot longer than I wanted to spend getting it working, but I believe this is because of the carrier ID and MCC being shared with Verizon instead of a separate one for XFinity mobile which forces it to default to the first Verizon APN setting which doesn't allow this to work. There are other ways to edit the APN configuration file, however I found it was quickest to do the actual file replacement with TWRP since that gives you full file system root access.

I had the worst time making the XFinity mobile work on Android Pie with the October patches in place and finally got it working. Basically, there was no way to edit the APN configuration even with root on the device via actual Android. What I did to fix this was the following...
-Followed the rooting procedure to get TWRP and Fastboot installed
-I then used "Termux" to copy the APN points configuration file to a writable location. In my case I copied the file from "\system\etc\apns-conf.xml" to a "\sdcard\Download". Keep a copy of the original file.
-I then simply copied the file over to my computer and opened it in NotePad++. I did a search for the following string in single quotes: 'carrier="Verizon"\n mcc="311" '
-This should pull up 5 results in the search and you should confirm that each of the lines has the mnc value set to 480, 'mnc="480"'. On each of the sections that came up, I switched the following variables as shown below...
apn="COMCAST.RSLR.VZWENTP"
authtype="0"
protocol="IP"
roaming_protocol="IP"
-Once you have edited the file, copy it to a writable location on the device, like "/sdcard/Download".
-This then requires rebooting into recovery mode with TWRP and you will need to make sure you have encryption and a PIN disabled on your device to make sure you have full access to the device file system.
-Within the main TWRP page, select "Mount" and you will need to have the "System" and "Data" partitions selected.
-Return to the main page and select "Advanced" and then "File Manager".
-Next, locate the original apns-conf.xml that you copied earlier. It should show up as being in "/system/system/apns-conf.xml". Click on that file, and select "chmod 755".
-Next, navigate to where you have the edited apn file located. Copy that file over to replace the apns configuration file at "/system/system/apns-conf.xml". Just make sure you have a backup of that original file before replacing it.
-Finally, reboot your phone into the OS and you should magically have Xfinity mobile working.

You couldn't cut and paste the file back with a root file manager? Maybe a magisk module? And does this lock you to Verizon?

I'm sure there are other ways to get the file back there, but I found my approach to be a quick bypass for other methods of getting root.
Regarding Verizon, It would probably break a Verizon connection for a sim carrier code of 311480. However, since this post is about Xfinity mobile, this is the quick way I got it working. In the future I want to change the priority on the APN configurations which may allow Xfinity mobile and Verizon to play nicely. The issues that have caused this are Android Pie restricting people from changing settings on the phones they own and Xfinity mobile being either too lazy or cheap to commit to their own carrier code and provide that information to manufacturers.

Breaking a Verizon contract for sim carrier code would be a drastic move, considering.. The only money you have to spend is $5 on a Verizon prepaid phone card. Go into a Verizon corporate store and they will give you a sim, ( it's $20 if you don't go to the corporate store)
