[Q] Cannot connect to any 4G Signal - Verizon Samsung Galaxy S 4

Hi,
I recently upgraded my ROM to HyperDrive which has been working great. I have attached an image of my specs... During the last few months I've seen my phone connect more and more to 3G instead of 4G, now just recently my phone no longer connects to any 4G at all even if I'm right next to the tower. Does any one have any ideas? I'm thinking it could be a localized problem with perhaps some of the towers, but I want to check everything on my end.
Also I was thinking about upgrading my Radio to see if that might help, my question is based on the information that I've provided with the attached image should I be able to upgrade my radio without having to wipe any data, or loose root? I've also wanted to upgrade to HyperDrive 10.2 but if I upgrade will that wipe my data too?
Thanks for your help!
p.s I have Verizon

Check your mobile network settings.should be able to dirty flash 10.2 and not loose your settings. But you could always use tibu then restore.

[Q] Problems with Wifi / 4G LTE with CM10

Hey guys,
was running Fresh 5.3.1 and went to CM 10 stable.
I did the following prior to this:
1. updated radio for s-on devices via TWRP to get to latest version
2. factory reset
3. wiped system
4. wiped cache + dalvik
5. flashed cm10
6. booted, download Titanium backup
7. Titanium complain about seeing an android device ID mistmatch and said it would fix it so I said yes
8. Observing that I cannot connect to LTE network (it won't connect and won't fail back to 3g). I can only connect to 3g when LTE isn't available. EDGE works fine.
9. Also noticing that the device doesn't switch APs well at all like my old stock ROM or FreshROM did. (It will hang on to a WIFI AP that has a weaker signal).
Anyone else having these issues? Should I not change the device ID with Titanium? Is that the cause?
TIA.

UPDATE 1: Also installed / flashed gapps for JB in there
UPDATE 2: I'm also running radio (baseband) 1.12.11.0809 (latest I believe). Never had any issues like this with any other ROM I've tried (stock, Fresh, OMJ, pokerom) ...
UPDATE 3: Going to try again without restored Android ID
UPDATE 4: I wiped and reflashed and did NOT restore previous Android ID via Titanium Backup and now 4G LTE works fine but I'm still having the WiFI AP issues - seems like this ROM doesn't have logic on the client side wifi stack to look for a stronger AP with the same BSSID and switch to it - I thought it was a native function of the spec but I guess not.
Now GPS doesn't work this release isn't what i would call stable
EDIT: Went into a sense based ROM and did the ##GPSCLRX# code from the dialer app, then using msl reader put in the password and after this got a GPS lock in maps then went back to cm10 and GPS is working fine again...
A few days after working all these kinks out it seems to be much better... definitely a rough start!
EDIT 2: Stock camera app is having problems... Requires rebooting the phone but third party camera apps seem to work fine.. Also intermittently having an issue where the phone seems happy to have no data connection even though it's clearly available (won't get 4G, 3G or edge)...

[Q] No Service After Bad Flash

Hi guys,
I managed to accidentally grab the ATT version of LiquidSmooth and flash it. Since then, I've had strange issues with service. Here's what I've tried:
Flashing (Verizon) versions of CM, LiquidSmooth, and Hyperdrive
Flashing the original and ME7 modems with Heimdall and Odin
Wiping data, system, caches, and fixing permissions before/after every flash
Randomly toggling Mobile Network settings (but I have no idea what I'm doing there)
[*[Searching everywhere I could think of on the forums
I had 0 service on either AOSP ROM I tried. Right now, I'm running Hyperdrive and getting weird results.
Sometimes it asks be to switch to "Global Mode" and shows that I'm roaming.
If I try to call, it says it can't find a mobile network and fails.
After leaving it sitting for a while (right after a clean flash), all the texts I missed came through.
If I try to text somebody, I'm warned that the mobile network is unavailable, but the text still goes through!
4G is working on Hyperdrive. Wifi still works on everything.
com.android.phone crashes when I try change the Network mode away from Global
I'd love to hear any suggestions you guys might have for me. Not sure what I have left to try.... is there a master reset for all of this?
Thanks!
EDIT
Some more details:
About Phone > Status in CM after fresh flash:
Network: Verizon
Signal Strength: 2147483647 (2^31 - 1) dBm, 255 (2 ^ 8 - 1) asu .......WHAT
Mobile network type: CDMA - 1xRTT:7
Service state: In service
Roaming: roaming
Mobile network: Disconnected
My phone number: something completely wrong
MEID, IMEI, ICCID are all there, but don't know how to tell if they're also whacked out
The APNs list is blank and my signal jumps between zero bars and a few bars + roaming. Call and text not working.
I've also attached my PIT file (grabbed with Heimdall). Have no idea how to read it.
Do you have a nandroid backup that includes your EFS partition? If so, I would try restoring it and seeing what happens. Sounds like something got out of whack in there and is giving your phone a hard time doing it's #1 job.
This is what ultimately switched me to the S4, my GNex randomly decided one day that it wasn't going to be a phone anymore, and I didn't have an EFS backup to restore in order to try and fix it.
Two things -
1. Always, always, always, make sure the ROM you are flashing is the correct ROM.
2. Always keep an ODIN file on handy of the full system image, here is the full MDK software, this WILL wipe all of your data - http://www.sxtpdevelopers.com/showthread.php?t=237

I don't have a backup. That will definitely be the first thing I do when I get this working again.

1. I know. LiquidSmooth could have done a better job of linking to the right place on their post, but it was still really dumb on my part.
2. Thanks for this! It looks like I'll be able to try this out tonight (slow connection). The SD card data is safe right? Also, I'm just downloading the tar - not sure what the exe is for.
I haven't used Odin for this since it was on version 1.8 or something (now it's over 3)... it looks like I still just choose the tar from the PDA block and hit go... no specific other settings needed for this phone / flash, right?
No luck :/ . I unzipped the stock restore, flashed in Odin (PDA), and booted fine. I have 4G and texts working, but no calling (mobile network not available) and calling my phone goes straight to voicemail. Also, it's very adamant about keeping me in Global mode over LTE/CDMA. This is the same state I was in earlier while running Hyperdrive, except now I don't have root.
I feel like I've tried everything there is to try. Does anyone have any further suggestions?
Are there any areas of software that don't get reset when flashing the stock images in Odin, and that could have been corrupted from the bad flash?
Thanks.
It's probably also worth mentioning that I'm warned about there being no mobile network when I send texts. I can cancel the dialog and they still go through. People can text me without issues.

I had the same happen to me when I was working on getting radio on MIUI ROM, after tinkering with the Sprint version, only 4G would work, and occasionally roaming would work. Every time I tried to make a call, it told me there was no mobile network available, and it constantly tried to switch into Global Mode instead of CDMA/LTE.
Sadly, the only thing that worked for me was getting my phone replaced with a brand new one. If you find anything that works please be sure that you post it, because someone else may end up doing the same thing.

Did you get it replaced via warranty? If so, did you need to do anything besides flashing a stock image in Odin beforehand?
Maybe try flashing the stock rooted ME7 that includes the new radios? Couldn't hurt at this point.
Edit: whoops, saw you already tried that
Sent from my SCH-I545 using xda app-developers app
Does anybody know whether ODIN / recovery deletes the partitions before writing new ones? If a file existed in the ATT rom, but not in the Verizon one, would it still be on my phone if I flashed the Verizon rom over the ATT one? Obviously this assumes a data / cache wipe in between. I'm really talking more about the other partitions.
Also, does anyone have any experience trying to get a replacement via warrantee after flashing? I've read all about the binary counter on our model, but didn't see any success / failure stories yet from people returning phones after flashing stock + unrooting.
Last question for now: is there any reason to believe that taking the recent update would help my situation? Maybe that could reset whatever is causing my calling issue.... just a random guess. I know that I'd lose any chance of getting root back (at least for a while).
Thanks again for the help guys!

[Q] No Data When Coming Off WIFI - CM11

Hello all-
Just flashed latest CM11 M9 ROM and love it so far. Only thing I noticed and not sure if its a bug or just something I'm missing, when I come off WIFI (either go out of range or turn off) I have no mobile data. It shows I have LTE but nothing until I reboot the phone. Once phone comes back I have cellular data but the issue will repeat once I go on WIFI. Am I missing something here or is this a bug? I did a full wipe prior to installing CM11.
D6503
Unlocked Bootloader
Latest 17.1.2.A.0.314 flashed prior to installing CM11.
T-Mobile LTE in U.S
did u ever get this fixed?
cause im having the same problem, grrrrr....

[Q] Razr XT912 on PP with working LTE, no voice/sms

I'm a new member here, I have done extensive search on this issue and have not found a solution yet.
My phone is Droid Razr Maxx XT912 that was flashed to PagePlus 3G months ago. I used a thread on Howard Forums that details the process for flashing various Droids to PP 3G.
It worked great, no problems. Last week I installed CyanogenMod 11 and it still worked good. Yesterday my PP LTE SIM arrived and I began the process of getting it to work on 4G. Settings in Mobile Network Settings are as follows: CDMA Subscription is set to RUIM/SIM, and Preferred Network Mode is set to Global(CDMA/EvDo/LTE/GSM/WCDMA. I tried a few of the modes, with same results.
The issue is that LTE works great, but I have no voice or SMS. MMS works fine. I have been back and forth with PP support, they programmed it for 4G and they say everything is correct on their end, which it probably is.
Is there an obvious setting I'm missing here? Again it is running CM11 with SafeStrap. Installing CM would have fully erased the 3G flash and settings, is that correct?
Thank you!

Installing CM has nothing to do with the flash, I think your best bet for it to work is to uninstall everything including safestrap, boot into fastboot, and RSD It to this: http://rootzwiki.com/topic/13566-how-to-droid-razr-return-to-stock/ This is the only known way to restore the 3g settings you flashed the onto the device. Make sure you download this update: http://sbf.droid-developers.org/download.php?device=9&file=156 and not the Blur_Version.98.72.165.XT912.Verizon.en.US update, because the latter has no way of rooting it. Sadly, the only way to get your phone to work is to wipe it completely. Good luck!:good:
Thanks for the reply. I decided to try that about an hour ago, figured out how to uninstall safestrap, then used RDS Lite to flash the stock ROM (it was the same one you linked to). Now voice, sms, and 4G data are working flawlessly. The only drawback is that I'm back to the unrooted stock ROM. If I would install CM11 now, should it stay working or was there an issue with CM? I am assuming the 3G flash had affected files that are not part of the ROM?

CyanogenMod ROM has nothing to do with the service. You should be fine installing CM. If you need a root tool, use this: http://forum.xda-developers.com/droid-razr/development/droid-razr-utility-xt913-jellybean-t2861798 and install safestrap, and then install the ROM of your choice. It doesn't matter if it is Stock Slot or Slot 1 etc., it should work fine.:good:
It was just the leftovers of the previous 3G flash that caused the original problems.
I got my PagePlus 3G flashed XT912 onto PP 4G LTE with no problems by flashing the phone back to stock with RSD Lite and the .165 update. I then (after activating the LTE sim with PP) rooted, installed Safestrap, and installed Axxionkat. The one thing to check on any rom is in Settings>Data>Network>CDMA+LTE/EvDo.

Wifi and Cellular Data Problem

If my Droid Incredible 4G LTE is connected to Wifi, it disconnects from Cellular Data. When I leave where ever it is connected to WifI, it won't connect back to cellular data. I have to turn off Wifi, then reboot the phone. I haven't tried something like switching to Airplane mode, I will try that. Has anybody else seen this issue? The phone is on Straight Talk Veriozon network, so is using SIM card for 4G LTE and CDMA for voice.
Are you stock?
No. Probably would help to mention that. S-OFF, partitions swapped and rooted CM 1.2.1 FWIW, this was happening with CM 11.2 before the partition swap. It wasn't happening before I did S-OFF and flashed CM 11.2 but I was also living in a different location for several months. It didn't start until I moved to where I am now.
I would try to do a clean reflash and see what happens.
I will think about that but I did a clean install when I did the partition swap and flashed the new ROM. I'd rather not do that again and have to set the phone back up again.
Today it seems to be better, I moved from Wifi to out and about and it switched to LTE properly.

I may have to try the reflash after all. The problem's gotten worse and now as of yesterday and today a reboot of the phone isn't getting me cellular data back. This did not start until we moved to a temporary place where I get voice service but not data at home. So the phone spends a lot of time on Wifi and not in a place where it can get data. So I'm wondering if the Verizon network is somehow forgetting about the phone or somesuch. At my old house, it was connected to Wifi but the data network was always available. The phone is S-Off with a custom bootloader and recovery. Assuming I wanted to try, can I put the stock ROM back on it without undoing all that?

If you want to go to stock, you will have to reverse the partition swap.

That part I understand. What I should have asked was "if I want to go back to the stock ROM, do I need to undo the custom recovery, relock the bootloader, go S-ON, etc? Any other ROMS besides CM I might try? That could tell me if it is the ROM or not but, again I did not have this issue until I moved to an area where I can get voice, but no data.
You should be able to remain s-off. here are the stock packages if you don't have them, http://android.cmphys.com/stock-fireball/

Thanks. I will grab a stock ROM. I really like CM 12.1 (and the swapped partitions) though. I was able to get the phone back to cellular data this morning while I was on a chat with Straight Talk. Why a reboot worked then but not the 3 other times I have no idea. I'm also wondering what happens the next time this happens if I go into APN settings and change it to one that doesn't work, then change it back.
Over looking at the stock ROM downloads I see a link to this patch:
http://review.cyanogenmod.org/#/c/93484/
The ROM I am running now was built on 05/26. I see a newer CM 12.1 ROM dated 06/12 that contains that patch so I will flash that ROM, probably next week. I'm on call this weekend and don't want to risk bricking the phone.
I'm running the 6/12 build and it seems happy. I only run my Fireball on WIFI since I switched to AT&T and have a Nexus 5 for my primary.

Ive thought about getting a new phone on a GSM network but where we are building our house I can't get a ATT signal there, so I'm stuck with Verizon.
