[Q] Problem with Radio. URGENT

After flashing the newest Paranoid Android and running for a few days I suddenly lost data. My phone states that my phone is roaming, so I tried turning data on and off and switching on airplane mode and then I settled on switching back to the ROM I was previously on, the latest MIUI and to my dismay saw that the same issue was occurring. So now my phone has no data on every rom I try and I dont know how to remedy this. If anyone has the same issue or anything to say that might help it would greatly appreciated. I still have 4 months to go on my contract and no money for Verizon's ETF or a replacement phone.

Have you tried re-installing your PRL? Call *228 and press send, use option 2. That'll re-load the preferred roaming list.

What recovery are you using (CWM or TWRP - and ver. #) and is your DI2 S-Off ? Please post your current Bootloader information (HBoot) and whether you have Backups for your (previous) Roms on your mSD card?
Assuming that your device can still making voice calls (SMS ??) - does it work over WiFi ? And, you have already done *228 option 1 - as it sometimes help reset it?
It is sometimes necessary to call VZW and speak to tech support for smartphone and they need to reset things and power cycle your device while you are on the line with them on a different phone to get you out of roaming, depending on the "radio" that your device is now. Hopefully, you did not somehow flashed the leaked non-VZW radio/kernel from China Telecom.
Before calling VZW, it would be helpful if you can flash a Sense-based ROM, either one of the stock zip file or Andybone's tweaked Sense Rom based on OTA, or the SkyRaider's Zeus v1.3 Sense Rom - and, if your phone was Sim-unlocked, can you check to see if it will work in GSM mode for voice & data (borrow a known-working AT&T or T-Mobile Sim card) Remember to do a Master Reset, wipe dalvik/cache & system before flashing a different Rom.
And, you should read up the sticky posts written here about restoring the device back to stock - just in case. The steps are slow & delicate, but it can be done - relax & don't panic.

I cannot make the call because I have no data

I have done multiple AntiVenom wipes to no avail, and only WiFi is working for me. I have not yet attempted to flash an older sense based Rom so I will try that. My only question is can VZW access and get my phone out of permanent roaming with my phone having no data or 2G?
P.S. - I did not flash the Chinese radio/kernel. Just checked

I see, I've seen DI2 in similar situations but usually, VZW tech support can do some resetting of the stored info on their database to try to restore it, and the best way to make that easier is to restore/go back to a near/pure Sense-based ROM. Once you do that, and you are prompted to "activate your phone OTA" - try to make a call - if you can dail out but the call cannot go thru, you should hear an automated voice msg. that there is error processing your call, ask you to hang up, power down & restart - and try again after waiting 5 to 10 minutes. The msg. will ask you to call # **** - make sure you can call from a home/office/different wireless number as they will go thru the troubleshooting & power cycle/reset process - should take 10 or 15 minutes, and will have you make a test call & verify connectivity success at the end. Informed them that you've done a Master Reset. (FYI - This involved updating, re-generating the good old "A" security key(s) used to identify the phone and the ESN/MEID stored for each device - somehow, the flashing of some Roms & wipe/reset totally dumped clean all of that info, and it needed to be re-established. )
The next step is to re-flash a Sense-based Rom that's stock or close to it -

From the device's Settings - About Phone - look for your radio's info - is it .0312 or .0320 (ICS-based) or an older radio like 0.1111 - after you flashed the Sense Rom, please check it again, and if you could - follow the Sticky's to get the 0.312 radio or even the 0.1111 radio in a Zip file, copy/move to mSD card, restart into Bootloader & flash it - restart and see if it can make calls/use data. If not, VZW tech support is your best friend to reset those Android handshaking of the security keys as stored on their database ...

I will be doing all of these as soon as I get home from school. Thank you for all your help so far

Try dialing some of the *228 variants such as *22801, *22802, and so on. I had a similar issue where the radio got all messed up. Verizon store was so close to selling me a new phone, but when I made this suggestion the sales guy tried it and it cleared up my issue. My prl I think was totally hosed and needed to be reprogrammed ota.

So I have moved back to stock Sense 2.3.3 with S-ON and there is still no working connection. At this point would I call VZW? and since i cannot call from my cell phone would i still call the *228 number or not? Is it possible for them to access my phone when it cannot connect?

Hmm, still no luck at all. Yeah, dial *228 first and does it dial out at all, or do you get any recorded msg. or nothing happened at all? Make a note of it - then, call VZW from another line (800) 922-0204, Monday-Sunday 6am-11pm - you want to reach smartphone / tech support - tell them you have the HTC DI2 and you are a customer. They will verify your personal info and then proceed to the next steps - and, try to find a way to communicate and/or re-establish communication with your device OTA. Make sure your device is at least 75% charged and at a good 3G signal area, and it's helpful to let them know that other VZW devices at the same physical location have coverage & working signal.
Let's see them go about resetting the system, etc. ...

No Signal / No Network

Hello, I am new here but have intermediate experience with devices.
Alright time to throw everyone for a loop lol, hopefully someone can help me out.
Here is my problem:
My phone is not connected to a network.
Here is what I have:
Samsung Galaxy S III with Metro PCS (NOT rooted, and with latest PRL and software updates)
What happened:
I woke up yesterday to find my phone not on Metros network, and not on a partner network. My 4G still works though, I can access internet but just can not call/txt or receive either.
In Settings > About Device > Status, here are some of the satus'...
Network: Searching for Service
Signal Strength: -93dBm 47asu
Mobile Network Type: LTE:14
Service State: Out of Service
Roaming: Not Roaming
My Phone Number: Unknown
Min: Unknown
PRL Version: 0
Things I've Done So Far:
Contacted Metro through phone support and Facebook support, neither could help fix the problem.
Took my phone into a Metro store and they wont honor a repair since my screen has a hairline crack in the screen. (which I will also say, they noted that already on my account...)
I've already went to *#22745927 and enabled the hidden menu multiple times (cause it disables with each restart) and I've went to **772 to view my MDN and MSID (MIN) and the MDN shows nothing and MSID has a 10 digit number (that's not the right number for my account), so I tried to edit them to the numbers that I know are correct and after I hit done, the phone restarts but then when it comes back on, nothings changed, and when viewing **772 again, the numbers don't save in the fields.
I know *#197328640# lets you access the service menu, but I don't really feel like touching any of that and making things worse (unless someone knows how to fix this issue through the service menu then ill do it)
Now that my long winded speech is done, its your turn to try and solve this dilemma and help me out please
I hope this is the right section to post in, sorry if it is not.
Thanks in advance to any help ^^ if anyone's got any other questions, ill try to answer them best as I can.

With your Device not being Rooted, the options are limited. Also a bit more clarification. You say you have no Signal / Network. But yet you also state you have 4G, and can access the Internet. That is a bit contradictory. It sounds like you may need to have the Device Flashed to Metro again, as something may have gone wonky.

Try to dial *228 then call and see if it will go through an activation process of some kind. If it does, let it go through until successful then reboot your phone.

Dial code ##72786# is supposed to reactivate you phone. That might fix your problem. Alternatively, you can try writing a PRL that you know works with Metro.
You can dial ##DATA# and go to View. Some ROMs (even stock ROMs) have a "Write PRL" option. If your ROM does not have that, you can try the HiddenMenu.apk trick and see if that fixes it for you.
If PRL is 0, then it is not scanning for sites. LTE is handled by a different function, not PRL. Voice/Text rely on PRL to function. Hopefully the PRL fix helps you.
I have attached hiddenmenu.apk that has PRL Write enabler. Just download and install as normal app. If it does not work and breaks your dialer, simply reboot. The HiddenMenu is only temporary until you reboot, it reverts back to hiddenmenu under /system.

Yea I'm not totally sure why I can access 4G data but not the network.
I brought my phone into a Corporate Metro store and they told me it might be a faulty CDMA antenna but I don't think an antenna issue would put my PRL to 0 and not show my phone number or MIN.

A CDMA Antenna being loose would not cause the Device to wipe data.

I tried to use the dialer with Wifi on, with 4G Data on. Even tried to use Metros "Joyn" service which lets you make calls and texts over data connection but the issue is, I did a factory reset already and by doing that it wiped the Joyn data from my phone. Now when I go to start "Joyn" up, it says it needs to be able to connect to Metros Network for the first time set-up so I cant do that since I cant connect to the mobile network (CDMA).
I still need to try what Ascertion said.

Yea I went there, I asked how to install it since I don't see a .apk file anywhere and they said the APK is the download.
Usually you can download a file with the extension .apk then install it from your phone easily but since there is no file in that download with the file extension ".apk" then I don't see how I can install...

Quick update:
Got that download to change to .APK by simply renaming the file extension.
But after I loaded it to my phone and tried running it, it greeted me with an "Application Not Installed" message.

[Q] Can't Get 4G Working on Any ROM/Radio except stock EC05

Hey everyone,
So I've been flashing ROMs on my Epic for about 2 years now, and I'm very VERY used to troubleshooting issues and solving them by either browsing the forums or doing it myself. However, I CANNOT get 4G to work on this phone except for stock EC05. I am currently running 4.3 with the latest gapps on the new Carbon Unofficial epicmtd ROM, with deodexed FC09 radio. I get **** service and can't connect to 4G. This happens consistently with all the ROM's I've used as well as the radios for anything past CM7. Does anyone know what I can do to remedy this situation? I would really like to not have to flash it over to another carrier due to sprint being horrible service providers.
tl;dr how do I get 4G working on FC09

I offer this suggestion with much caution....
Ever consider using EFS Clear within Odin? You'll have to setup your phone again, but it could help.
WARNING: This will completely delete your phone identification and you won't be able to reconnect to Sprint's network until you set it up manually again. Write down all your pertinent information, such as MEID #, phone number, etc..
From stock FC09, I recall having to do the following to enter the information:
Enter in the dialpad: ##785468#
Press Edit
Touch the number area to input your phone number.
Input your phone like: 5551112222 (Where you have area code and then phone with no dashes, spaces or parenthesis)
Hit return
Input your phone number like before in the next field
Hit return
Hit done
Manually update your profile in Settings > About Phone > Status
You can always just call up customer care and ask them the steps on how to reconnect your phone to the network. I just said a little cousin starting hitting buttons and when I grabbed the phone it refused to allow calls, text and data.

Nevermind, I understand now. How much success have you had with this process? And do I just need the phone's status splash screen information or am I manually entering EVERYTHING?

[Q] CM11.0, 20140608, M7 Snapshot - Unable to get signal from radio

I started to experiment with different custom ROMs available for the d2att (now, apparently called the d2lte). My phone is using TeamWin 2.6.3.1 for recovery, I have been using it for everything. So far I have only been familiar with two certain ROMs: Cyanogenmod and CarbonROM. I have not flashed anything except for the recovery.
I complete the installation of my new ROM by first wiping cache, dalvik, data and system. My ROMs are stored on an external SD.
CarbonROM was the first one to be installed, but I found it quite buggy and unstable. I have since been using different snapshots of CM to test functionality and stability...since I plan to hang up my LG G2 and start using my SGS3 w/7200mAh battery as my daily phone. So it needs to be very reliable. I also enjoy picking with settings so the more settings the better.
So, question number #1:
When I install CM the normal way, add my APN, and select the proper mobile network mode, how come I cannot get a signal, no matter what I try? I have searched around many forums for the answer to this...many have nothing to do with my problem or are using different phones. I can confirm my SIM card works, as it was used in my LG G2. Carrier is Virgin Mobile Canada. Network mode is GSM/WCDMA Auto. It does not work with any other modes including Global.
Q #2:
If I plan on using custom KK (4.4.2) ROMs, is there anything extra I need to flash to the phone in order for the cell radio to work successfully? When I researched this, I found lots of people talking about flashing a custom bootloader, but I could not find an exact answer to my question. I would rather not brick my phone by attempting this blindly.
Q #3:
Since I am looking for a reliable custom ROM, is CM the best developer to choose? Is there a more reliable ROM out there?
Mike
EDIT: I did more reaseach on bootloaders and modem firmware and found that my bootloader is already at the most recent version. I did find however that my modem firmware was out of date, so I updated from UEMK5 to UEND3. This however did not solve my problem as I still have no service...
I am contemplating now about starting from scratch and wiping my internal storage... will this help or is it unnecessary?

For question # 1, do you have a proper imei after installing CM11? You can check it in the dialer by typing in *#06#.
For question #2, the modem must be compatible with the bootloader. Custom ROMs will only install if the phone has a compatible bootloader.
For question #2, I prefer Validus which is an AOSP-based ROM.

I have an IMEI number. That is what has me kind of confused...everything is there to show signal, it's just that it will not pick up a tower. When I throw a SIM card in it recognizes it. One thing to also mention is it pins the signal at 0, -1, or 258692378... or another outrageous number.

First things first have you followed the method of going back to a stock TW ROM, obtaining a GPS lock, and then flashed your Custom KitKat rom?

I am now on stock 4.3 firmware. I have obtained a GPS lock.
No service at all.
But... I had a funny feeling, so I went into stock android recovery and wiped cache...and voila, service!
Only problem is, I'm losing it almost constantly. The only way to fix it is by wiping the cache, but I can't keep doing that whenever I lose service.
Will I be okay to flash the custom recovery and custom ROM at this point?

Do you have the latest modem installed?

If you are still on the Stock TW ROM here is a method to try. It will clear most of your mobile data problems.
1. Enter the Samsung service mode by typing this code into the dial pad *#197328640#
2. Then go to Mainmenu>UMTS>Common>NV REBUILD>NV REBUILD> (Important: don't exit the menu yet!)
3. Wait 30+ sec
4. Long press power button and select "Restart / Reboot"
5. Now check your GPS from any software that may use GPS like "Maps" or "GPS Status"

EDIT: Afterwards you should be good to go on your custom ROM. This issue seems to have arisen when a d2lte build broke most people's LTE/Mobile data.

You're running the most recent release so I'm not sure what's causing the issue.

I have found the problem with the service. I live in an area where signal is not too great. My LG G2 has a tendency to pick up the correct tower for my area, but my Galaxy S3 does not choose the same tower... It looks for one in a completely different direction.
Forgive me, this thread is going to take a bit of a turn.
Is there any way to choose which cell tower the phone connects to? In my area there is one directly east and the other is directly west. I need the western tower in order to make/receive calls/text and in order to get any data reception. Right now where my phone sits, it does not connect to the western tower so I cannot use it. I used OpenSignal to observe which tower both phones connect to.
The other issue I found is my extended battery (Anker 7200) also interferes with reception quite a bit. In town, it's not noticeable. But out on my acreage it stops my phone from getting any signal. I compared it to my LG G2 and my Galaxy S3 with the old 2100mAh battery. The G2 hovers around -95, S3 w/OEM battery at -101 and the S3 w/Anker battery at -113 (no service).

Try changing the mode to LTE only under your settings. This may force the stronger connection.

Unfortunately that won't work either. In my area I can only pick up HSPA....

Hmm. Out of curiosity, have you tried a different ROM on 4.4.2? I've had weird issues with ROMs and signal, ie MIUI caused me to have my signal cut in and out at random intervals. Worth a shot at least. I've been using SlimKat if you want one for reference (probably the quickest download due to size).
Unfortunately all I can suggest is trying to play with tasker and seeing if you can get it to skip over the crap tower, but to my knowledge there's no way to prevent connection to said tower.
I guess if you wanna get into a gray area you could modify said tower....but I claim no responsibility for your actions with that

I've been using Liquidsmooth the past few nights and am losing signal more than ever.
Would the OS control how the modem is used? I would think that it's hardware only that changes how and when you get service.
I'm going to try the UEND3 modem firmware and see if that makes a difference. Also going to try SlimKat like you suggested.

[Q] How to change PRL

Has anyone found a way to flash / change the PRL on the Note 4?

I found a way to flash a PRL. I was able to successfully load older prl that are withing the same series. I used DFS CDMA TOOL v. 14.10.21.0.
1. Turn off wifi and data on the phone.
2. press ##3424# on phone.
3. Qualcomm usb setting
4. Select RMNET+DM+MODEM.
5. ON DFS Click on port on and select the port your phone is displayed.
6. Enter your MSL right below.
7. Once you enter the MSL click the SPC icon.
8. Next click on NAM.
9. On the bottom right hand corner click Load and select the PRL you want and click WRITE.
10. Return to ##3424#, Qualcomm usb setting, select MTP and Restart.
11. Enable your wifi and data.

I was unable to load any 56*** series PRL.
I was able to flash 56022 with the steps on post #2. Below is the link to all PRL.

Thanks for the info. I was able to flash the 503 PRL from S4GRU, but, the one I would prefer, 513, won't take. I may have to try again when the kids are in bed tonight. I think it's based on a 56xxx series PRL, so it might just flat out not work.

I'm glad to see that at least you were able to flash an older one. I tried various ones from the 56*** series and no luck. Hopefully you or someone else gets the ball from here. Im glad i was able to go back to an older prl. Now my phone is not switching towers every 2 secs.

Thanks! Unfortunately I had the same issue with 56xxx prls too...none of them would flash ..and that's the best one too!!

I goofed around with this a little this morning and had no luck with any Corporate PRLs. Just says process destroyed every time I hit write.

Same here from day one.

Will PRL change allow simo voice/data calls?
on my old phones i was able to do both phone call and data...
primarily when driving using google maps and getting an incoming call./text. now with spark i cant do this .
will updating a pRL... lets say to a tmobile tower allow me to do that again?
also back with i had an s4 and put a CM11 rom on it. that room gave me the option to make all calls VoIP.... anyway way to add that single option to a rom??

55022
Update your PRLs.
55022 is out. Im stock with DM not frozen, obtained via the Update PRL .

I have a much simpler option and can confirm this works just fine.
If you are rooted but do not have a custom recovery you can download the zip file in this link and extract HiddenMenu.apk located in the file under /system/app and manually push it into the /system/app folder on your phone. Then change the permissions to 0755
http://forum.xda-developers.com/showthread.php?p=54201284
(The file says deodexed but I'm running stock odexed rom and it worked just fine, also remember to back up original HiddenMenu.apk)
After that follow these steps
1. Extract TEST.prl from the PRL Zip that you want to flash
2. Place TEST.prl in the root of the /sdcard folder
(DO NOT put it in /mnt/extSdCard)
3. Turn off WIFI and Mobile Data on the phone
4. Dial ##DATA# (##3282#) and select "View"
5. Select PRL WRITE then hit the button labeled "PRL WRITE" (your device will reboot at this point)
6. Once your device turns back on, turn WIFI and Mobile Data back on.
7. Goto Settings -> About device -> Status and confirm "PRL version" matches the version you wished to flash
Hope this helps! please thank me if so:thumbup:

Was able to get 56022 as well. Can anybody recommend a paticular prl for best lte connectivity?

LTE is not affected by the PRL.

Ok, I just glanced over some of the links and thought the PRL determined what towers were available. So it only affects roaming?

PRL = preferred roaming list. Your phone will always scan for any of Spirit's LTE bands first. If it finds nothing on those three bands, it will then look for a Sprint CDMA (3G) signal. Failing to find one, it will then look to the PRL file to see what networks and at what speeds you (Sprint) are authorized to connect to and in what order. In a nutshell anyway.

Ahh, makes sense. Was just looking for any way to get better LTE connectivity and have the phone hold that connection.

This process works on OG5. Flashed 56025 PRL
