Flashed US998 on Sprint Network - MMS Issues - LG V30 Questions & Answers

I have the LS998 on Sprint. Following the wtf guides, I used LGUp to flash US998 and then I rooted it. Before I did that, I made a dump of all three of my modem files and took a screen shot of all my apns within the Secret menu.
After getting on US998 8.0.0, I used adb to flash my modems back into my phone (I hear that not only is that required to get Sprint lte bands back, but each individual v30 has its own modem files too that are required). I then rebooted and added my APNs back from within the hidden menu again. Rebooted once more and switched from "global" to "lte/cdma" and selected my correct apn as the one to go.
Everything was working perfect for a little bit, but now I am having issues received text messages. I can send them just fine. I am getting phone calls just fine and sending phone calls just fine. I have lte and am able to connect to the internet. I don't understand why i was receiving messages and now I am not. When I go into phone status, it shows my phone number was picked up fine from Sprint and I can go into My Sprint app and it recognizes that I am on the correct device.
As a last resort, I found the Stock Sprint rom that someone posted on XDA here that I can revert back to if nothing works, but I HATE the Sprint rom. They changed so much to it for the worse and of course all the bloatware. I know I can use titanium backup to remove all the bloatware since I can retain root, but I just love the simplicity and cleaness of the US998 stock rom that sprint ruined in their version of it.
Is there anything I am missing or any help in order to get my text messages back for good without reverting? Thank you!

@Klenon
Add apns I linked you to yesterday and select those apns I never had any problems using those
Also I never changed global to lte/cdma

Hey man,
I used those APNs before I reached out in that comment and I was getting all sorts of weird. But I was able to use that post to get back to LS998 to start over, which this second time around is when I did things right like dumping my modems when I'm still on LS998 and grabbing my original apns which were similiar to that one, but a little different. That is when I was working perfectly for about half the day and then stopped getting messages.
I did forget to upgrade rpl and profile before I dumped my modems and grabbed my apns though. So I don't know if that could be my issue.
Thank you for your help so far.
Do you mind telling me all the steps you took form beginning to end in case I missed something?

If you want to stay on us998
Flash rom
Set up romadd apns and select
Boot to TWRP flash modem (I only use the single modem file not all 3)
Reboot and that's it
On us998 you don't need you use hidden menu to add apns you can just add them

When you say flash only one modem was that just the modem and not the numbered ones? I saw another post stating the numbered ones had something to do with your specific device after updatong prl and profile.
Tjats basically all the steps I did. The first time i did it I added the apn that you linked to, then the next time I flashed all three modems and added my own apns from ls988 Rom. And I jusst dont understand why it did work so flawlessly and then decided not to. I think once my contract with Sprint is up I'm moving to a better provider. Ive been with sprint for like 6 years and everything about them including customet service has just beem deteriorating.

[Q] Flashed Eris For Cricket, Reverted to Verizon, No 3g :(

So I bought a phone (Eris) off Craigslist to flash it to Cricket. I was able to get all the settings right in order to have MMS\3g using EPST and enjoyed it for a while. Unfortunately, I recently moved to a town that does not have Cricket in it, so I installed a new rom and was able to Activate my phone with Verizon. Unfortunately, I have been unable to access 3g on the Verizon network and was wondering if anyone could post the correct settings to use with epst in order to get 3g working.
Please, I have searched for them but am either using the wrong search term or just cant find a thread that has the settings I need.
I am currently using KaosFroyo V32 but by the time anyone reads this I will have reverted to a rom which allows me to use EPST.
Thanks,
Q
So I switched over to the Xtrsenserom and, just as I thought, the settings in EPST are all still setup for cricket service.
Im going to try #228 and see what happens now that Im not on a Froyo-based Rom anymore
Peace...
AAARrrgggghhh!!!
This so sucks!! The ota did not change the settings (or at least not enough to allow mobile internet) It was so easy to find the settings i needed to change in order to have mobile internet through Cricket. Why is it so hard to find the ones to revert back? Under the NAM Name it still says cricket but my MDN is correct but I can tell a bunch of the numbers in subsequent settings are connected to my old Cricket account... Please help!!
It's *228 for one. Which page in EPST do you need?
Ah I figured it out. It had my old number as min and crickets info for login and a few other abnormalities resulting from cricket. I gotta say this version of Android 2.1 I reverted to in order to access EPST is real nice. I don't think im going back to Froyo for a while. I forgot how nice the dialpad is where you can just dial in part of someones name and all the numbers that fit your input start appearing
can you send me the settings you used in EPST for verizon. I think I may be having similar issues.
Use the verizon RUU.
This will put everything back, you can *228, reroot, then restore your nand backup and uninstall auto start.

You know what, just throw a verizon prl file in there, and you should be able to *228.
Try that alltel verizon hybrids one if you can't find any others.

I'm sorry to bring this thread back up.
I just went through 3 days of frustration on this issue and since this thread is the top google result, I want to help others.
I bought a used Droid Incredible that was flashed to Cricket. We had the phone flashed back to Verizon from a local Cricket dealer. However, my data wasn't working at all. After spending 2 hours on the phone with VZW, I learned of ##778. The rep only went through two menus and only one option was different (home nid/sid). It didn't help changing it, and in fact, everytime I do *228, it just goes back to what was in there originally. So anyway...I found the security menu later that night. Noticed that HDR AN AUTH Password and PPP Password said 'cricket'. I deleted that, reboot, and then saw 1x finally pop up, but it wouldn't stick.
Changing PPP Password to vzw made 1x work, but the connection would constantly try to obtain 3g, and reset the connection so it was still unusable for the most part.
Noticed on the Eris (previous phone), those Password values were encrypted...Google research suggested a painful adventure of memory dumps, etc, etc.
Then I found another post.
http://forum.xda-developers.com/showpost.php?p=2563813&postcount=32
I blanked out the two password fields, committed, then went to home sid settings (or home sid profile) and changed network type from simple ip mode to mobile ip preferred. Commit, reboot and bam! 3G was there!. I didn't have to, but a *228 may be necessary. The two password fields got updated automagically and now have encrypted values in them. Life is good.
Edit: just wanted to state that in the middle of trying to get data working, I flashed over the verizon RUU, which didn't help immediately, but may have been a compounding solution.

HELP! APN On Dev Edition

Ok, I suddenly have lost LTE data and cannot make phone calls.
I have pulled the sim card and reinserted but I keep getting a popup window asking me if I want to connect to Global and not CDMA/LTE. I change the request to LTE and make sure setting is there.
It won't connect to 4G. and keeps asking about Global.
I am rooted and ROM'd with unlocked bootloader and have even tried my trusty stock image -- no go!
All of my ROM backups have the same issue and I can't place a call.
:crying:
Yes, my bill is paid and in order.
What can I do? I doubt VZW will help me since it is a Dev Edition and I purchased through Samsung, not them.
APN settings seem to be blacked out so I cant change. It does allow me to delete it.
HELP! I need to place calls.

If it persists across different roms it sounds like either faulty sim or for some reason your modem or kernel is corrupted. I would re flash modem. After that try to re flash kernel. If that fails a new sim might be in order. I presume you have checked with another phone to be sure it's not a VZW problem.

Thanks! I will try the modem route first and then the kernel route.
Although each ROM has a different kernel, so I don't think that is the issue.
Yes, no problem with VZW as the other half's phone is working.
Data works on LTE for Internet but can't place any calls and all received calls do not ring phone: goes into VM.
Edit: at Verizon and not SIM card. New SIM card gives me voice but no data. Says voice roaming.
Ok, here is the problem after 2 new sim cards: Data is showing as "CDMA RX1TT" I cannot get data or voice now. Says voice is roaming with a triangle.
Is this a software setting or hardware setting? Something has changed on my phone, despite changing from stock to ROMS, etc.
VZW store is at a loss and though the rep was good, suggested I call top tier VZW support tomorrow and made notes in my account.
So, any clues as to what could cause this? Is my Dev phone now shot?
If it truly is an APN issue i can post my APN from my Verizon SGS4 and you can use an app called APN backup and restore to push it to your phone or push it manually using root explore and then set permissions. Let me know.

You might have a corrupted EFS partition in which case you would need to restore a good copy of that. Some of the time its in LTE/GSM mode for whatever reason in which case you would need to change it to LTE/CDMA mode.

I had a "DUH" moment when I was in a similar situation. I had forgotten that I had enabled the hidden menu on my DevS4 and changed the "band" preferences to try and force the AWS band. This took the phone off of "automatic band connecting" and I was unable to connect to data. Once I remembered what I had done, I simply when back into the menu and switched from forcing AWS band back to "automatic". Just my 2 cents.

Hello Everyone! Sorry for the delay. Actually, this is what kinda occurred, as the 1/15 build of OctOs ROM which I flashed had an issue and it was posted on Facebook, which I didn't see until Saturday. It changed the CDMA subscription to NV and so even with stock or other ROM backup images, it carried over and didn't re-adjust. I had to reinstall that bad ROM, make some changes per OctOs instructions and BAM: all is well.
As you know on stock rooted, one cannot change certain settings and they were greyed out.
At least I got another backup sim card from VZW should I ever need to activate an older phone.
Thanks for everyone's help!

LS990 Working on Big Red

I installed the ZV8 L update via TWRP to mantain root.
At the same time I proceeded to use the GSM unlock method by changing the build.prop from SPR to either spr, ATT, TMO, VZW, KDDI, and other carriers that are in the hidden menu to no avail. Each time the setting menu would change to the carrier selected.
I decided to try the carrier unlock via the "carrier folder copy method" found here on XDA. After doing the mod, the phone was working on GSM without a hickup, so I can confirm it does unlock the GSM part, also, I did a network scan, it detected ATT and conected to ATT. I DID NOT try to make a test call. (I am from south of the border (Mexico) but live in a border town, I pick up US carriers because of the proximity to the US) Today I traveled to the US, but was so busy with other things, that I totally forgot to see it the phone would connect to ATT, since ATT is my service provider when I roam in the US.
Just as I was going in to Mexico I remembered about the phone, got it, and noticed that in the carrier it said "LG" instead of the usual ATT carrier when I roam. I tried to do a call, but a recording I have never heard before said that my account was not configured for this type of call.
By then I was in Mexico, and could not do any more tests. I reset the phone, and it picked up my mexican carrier without a problem.
I decided to do the NV/RUIM trick from this post..... http://forum.xda-developers.com/sprint-lg-g3/general/unlock-sprint-ls990-cdma-carrier-t2985523
After the mod, my phone rebooted with no service. Right before the reboot, I pulled the battery and placed my nano VZW sim in.
After that I went ahead and modified the build.prop and changed the carrier from SPR to VZW. Did a reboot and when the phone came on I got a couple of UI crashes and hiddenmenu crashes. I went to the mobile settings and changed the phone to Global, and, in shortcut master I changed the network setting to CDMA/LTE/EVdo. A few seconds later, I got signal bars and went ahead to make a test call........at first I got a busy signal, decided to make another test call....
Call went though. Voice was perfect without issues.
Random UI and HiddenMenu crashes, but call go in and out.
In the carrier I get "Partial Service Functionality"
These tests have been carried out in MEXICO, while I am roaming with the mexican carrier, I am not in the US and cannot test the call features, SMS, and/or LTE.
Any one out there in the US would like to test this out?
Also, any coder out there able to figure out how to fix the random UI and hidden menu crashes?
If I flash a Verizon Baseband to the phone, will I brick the phone?
Will I still be able to boot the phone to TWRP to reflash a Sprint BB?
Would a guide of what I did be necesary?
Too soon to post a link for beer donations, or is this something that has/is been done?
UPDATE: I dialed *228 and pop up came up (2nd picture)
Reserved.... who knows.

[Q] Using phone abroad, can't connect to data network

Hi everyone, I've read quite a few discussions on here but this is my first post.
I've recently moved to Sweden from the US with my sprint lg g3. Before I moved, sprint told me that my plan covers me to use voice and data for free, but only with a specific carrier. They said that it's already taken care of and I shouldn't need to do anything when I get there.
That was one week ago. I've been in Sweden for a week and every day of that week I've spent around an hour on the phone with sprint trying to get my phone to connect to the data network. I get voice just fine, but, from what I understand, the phone is wanting to connect to a different carrier for data and he doesn't know how to force it to connect to the right one.
So, after some digging, it looks like I might be able to create a new apn and maybe connect to the right data network that way? Going down this path, I can't by default add any apns, so I followed another discussion and installed root tweaker to be able to fix that. My phone is indeed rooted on lollipop, but the tweaker doesn't seem to change anything for the apn screen, I still can't add nor edit them.
So, my two questions are, should I even be messing with apns (and if not, what should I be doing), and if I should mess with apns, how can I edit it/make a new one?
Thanks so much in advance, I'm getting frustrated with the sprint guys so I'm trying to take some initiative myself.

Try flashing (in recovery) my "MegaAPN" file. It should support a HUGE amount of carriers. You may also need to unlock your apn's so you can edit them. You can do that by searching for this: com.lge.hiddenmenu.settings.ApnUnlock in shortcut master (lite or pro) and clicking the name of the shortcut then just press the "Launch" button (looks like a little Space Ship). Then just press the little "Unlock APN" button and Reboot. You should now beable to add/edit and remove APN's.
Hope this helps:good:
Hi!
I've tried the shortcut master to unlock my apn, and a dialogue bowstring my apn is unlocked appeared, but after a reboot I still have no options to add or edit an apn.
Luckily I do know the carrier I need to be on, and I've found the apn information for that carrier, I just need to be able to add it in the phone I guess.
Thanks for your help!

Galaxy S4 I545 (Verizon) outbound text msgs not working with Tmobile SIM card

Hey everyone. I just bought an unlocked, unused (new) galaxy s4 I545 (Verizon) and it wont send out text msgs with my T-mobile sim card. I do receive (inbound) text; but no outbound text msgs. Calls and web surfing work fine.
I'm aware that this is very common problem when trying to go from Verizon to Tmobile with galaxy S4 phones, but i have not been able to find a straightforward solution to this exact issue. Has anyone been able to solve this? I did find this one thread that addressed this problem, but it's quite confusing --> http://forum.xda-developers.com/galaxy-s4-verizon/help/noob-s-stuck-oc1-lollipop-t3116732

I tried changing all the APN settings. These are the same ones T-mobile had me switch. There is another post where the user discovered his SMS/MMS works when on 3g, but not 4g. The workaround was to Root and then change a setting to use only 3G. My problem is that I cannot get Kingroot or any other app to root my phone. They all fail.

What build are you running?
F1
I was able to root my I545 yesterday after months in limbo........ I used Kingroot (not Kingoroot). I tried it 7 times from the phone, and it failed.... then as recommended by many users, I scrolled to the bottom of the kingroot page on phone (after root failed). It said I should use the desktop to root it. Soooooo I set Google translate to "English" and loaded KR (Kingroot) on my desktop.... It WOULD NOT open Kingroot. So (on my desktop) I opened KR WITHOUT english translation. and it was running (on my desktop). Once it was opened, everything was in Chinese (of course). BUT.... it has screenshots that walk you through it (although in Chinese). I attempted to root the phone (by using screenshots only, since I do not know Chinese), and it rooted it first time My advice, use Kingroot as described using your DESKTOP computer and cable. That should do it
NOW my problem, is I have to flash my VZW S4 (OC1 lollipop), to a t-mobile rom...... so I can have wifi calling with my dedicated number Of topic:..... if anyone can do some Q&A with me on that topic I would be appreciate it GREATLY.
Hope that helps ya
---------- Post added at 08:30 AM ---------- Previous post was at 08:09 AM ----------
BTW.... I have the same issue with my text messages (no outbound sms) when I am on 4G. There is a write up on the forums on how to possibly remedy that, but I get hit with.... "MD5 has to many hashes" and I cant go any further... Im still trying to figure out what the hell MD5 is.
ATTENTION to MODS, and OP's:
I am seeing more and more people (like me) whom are coming to XDA because they have a Verizon S4 (whether its kit kat, or Lollipop), and they are using a T mobile sim. I have made an assimilation though.... These people that are coming to XDA have little, to NO root, rom, kernel, experience what so ever (just like me as well). IWe are looking for a fix (I myself want to flash my phone to a T-mobile rom, activate wifi calling, and be able to send/recieve sms continually). Is there anything that anyone could write to address JUST 2 things......... (1 how to get a Verizon S4 with kit kat, and with lollipop to have a t-mobile rom, 2) If somone elects to leave the phone a Verizon phone, a step by step (tailored for noobs like me and many many others) process for fixing the sms issues from having a T-mobile sim... The write up for the second request thats out there is okay, BUT the common problem is a "MD5" issue when you try to download hiddenmenu.apk. Without being able to download the "hiddenmenu" to our phone, we can't even get to step 2 of the "fixing sms issues"...
Please OP's, and mods........ remember in this tense world we live in, remember one thing......... "NOOB LIVES MATTER!"...... C'mon noobs, say it with me! :good:
I don't think the ROM matters. As long as it's a Verizon variant of the phone you won't be able to flash T-Mobile ROM's. This issue is most likely an APN setting issue. Did you ever try flashing the stock OC1 build for the VZW GS4?
I have the OTA lollipop update.... it came in two parts. The apn settings are set per tmobile . I can send sms however only when it switches to 3g. The problem is, on lollipop, you cant toggle between 4g and 3g like kit kat would allow. So its hit and miss (much more miss than hit...lol). From the sounds of it, the radio mhz are different between vzw and tmobile regarding 4g. The other dilemma i have is that i live in the mountains of oregon so i am 3 miles outside the network.... therefore i need wifi calling. I have a google voice number, but i need my assigned phone number for work purposes.
If what you say is true regarding a rom specific for vzw, i guess i need a vzw based custom rom, that will allow me wifi calling, and also fix my sms 4g issue...
---------- Post added at 05:52 PM ---------- Previous post was at 05:13 PM ----------
Speaking of the 3g and 4g thing...... since i have rooted my phone (via kingroot), and installed supersu, am i able to turn off 4g? And if so, how do i do that?
No, you need a T-Mobile ROM that has wifi calling enabled. But like I said this is probably more an APN setting issue than any.
Here
This ^^^ is a link to the manual if you think you can find something useful in there. I've used like 20 apps that all claim they can Toggle LTE data but I've yet to find one the doesn't just bring me right back to the settings of the phone. I've heard rumors about an app that's $1 on the play store that can do it for the GS4 but I can't confirm that. It seems as though you need some special settings provided by the service provider in the ROM that allows for such changes. I might recommend looking into whether you can flash a T-Mobile ROM to the VZW variant.
http://images10.newegg.com/UploadFi...052213_F4_Rev_FINAL_Rev1_Web1403840347272.pdf
Thanks for the link for the manual. I just checked the APN settings, and they are where they need to be. There are only two different settings/entries that i have found for mmsc, and both leave me with this problem. I have researched, and can find a fix for it if i had jelly bean, or kit kat..... but i have lollipop
I am searching to see if this vzw phone will take a tmobile rom (or a variant). If it will, than i might be in business. Does anybody know if i can roll this back to kit kat, or jellybean since i am now rooted?
Unfortunately once the GS4 is on the 5.0 build the phone's bootloader does not support downgrading-I've tried. I, like you, have a the lollipop build (OC1) on my S4 and I really wish I had not taking that update. Lost story short it was an accident I shan't repeat.
finally got it working
I also ran into a wall after taking my wife s4 i545 from Verizon to T mobile. I finally got everything working. the phone is on OF1 so there's a lot of things you need to do they are all here but scattered and very hard to find. you need to root with wondershare mobilego. then you have to odin flash an OC1 kernel then change the settings to the T mobile settings then get this app called Advance signal status and change the defaul text message number from the verizon to the t mobile number and the mobile networks there too(you want GSM auto). after all that you'll be on 3g or H+ for your data but its not too bad and everything else works great including text. total time about 1 hour but just putting things together is where your time goes. hope it helps
Note if your T-Mobile SIM used to be in an iPhone
I was having crazy trouble getting my SMS and MMS working with a stock Verizon Samsung S4 (SICH-545) ROM. I believe most of the problems I had were due to the fact that I was previously using an iPhone4 as my T-Mobile device. After searching through the internet and finding the proper settings for T-Mobile APN, I was able to quickly get phone calls and 4G data working. However, there were some things that took a while to get working. Initially, I could receive SMS, but not send SMS, nor send/receive MMS. It's now working and here's what needed to be done:
Remove the phone from iMessage (allowed sending of SMS)
Remove the phone from iCloud (allowed sending/receipt of MMS)
Lastly, to ensure you get Voicemail access, change the Voicemail number in your Settings. To get directly to VoiceMail with T-Mobile, dial '123'. There's a different number for accessing from a different phone, but this works directly from your T-Mo phone.
I did not get a chance to read all of the responses on this thread, however, I can probably help resolve if the answer is not already embedded in this thread.
I have successfully rooted a Verizon SCH-I545 with stock Verizon ROM and got SMS/MMS to work. Unfortunately, I have only been successful through locking out LTE. If you want more detail please IM me. Otherwise, here is a quick overview:
1. Root SCH-I545 (There are a handful of methods but Wondershare MobileGO seems to do it for me.)
2. Update APN’s to T-Mobile (fast.tmobile.com)
3. Download Advanced Signal Status. Change Data Signal to lock GSM/CDMA (PRL)
4. Reboot and Enjoy
Worked on several handsets I have flashed.
NOTE: A simpler method would be to flash ALBE95_S6 using Flash Fire then there is no need to deal with locking your data signal through Advanced Signal Status, just use the default Network Settings within the ROM.
Hope this helps.
That doesn't work for me. I can't access Additional Info, AND even when I could, DATA would disconnect... so I'd have calls and texts.. but no data.

I did the same, flashfire albe s6, rooted, busybox, apn change, advanced settings gsm/umts, lost wifi too, but....
I was able to fix it. There is a wifi fix in one of the earlier posts: http://forum.xda-developers.com/galaxy-s4-verizon/general/gogolies-wifi-fixes-t3099951 forgot which one I used. but it all works now (on tmobile that is)
Oh, in case you went and downloaded the latest ota from verizon (f*** you very much), like I did, lol, there's a wifi fix for the OC1 bootloader too, for us flashfire people: https://www.androidfilehost.com/?fid=23991606952597069
here's the directions, nice and slow
root the phone, I used kingroot, then converted to supersu, then install busybox
then install safestrap, if you can (your bootloader is older than and not including OC1) or (if you went OC1 or newer), then install flashfire, like I did. Only thing is, if you muff something up and only have flashfire and not "real" recovery, other than the stock one, it gets kinda stick fixing it, (you have to odin in the verizon stock full image of OC1 and start over, I think, I forgot).
then I installed albes s6 rom, I think its in the unified or maybe att s4 section. its easy to find. Its prerooted, so I just updated busybox and then re-installed flashfire. when you install albes make sure you do a full wipe and flash the oc1 bootloader after the albe rom, in flashfire, that's the only way it'll boot.
ok, so you got albes, now you need to change the apn. I use idoneapp gt 3.8. The guy doesnt give it away for free anymore, and I don't blame him, I was just lucky enough to grab 3.5 (which you need to install 3.8) and 3.8 before he decided to charge for it. Its for the sprint s4, but it allows you to do alot of stuff, even on the verizon variety (lol). You can change the apn, allow wifi tethering, get into the advanced menu to change the radios (gsm, cdma, wcdma, lte, etc) (or you can dial *#*#4636#*#* - sometimes doesnt work though. There are other apps on the playstore to change the apn too, so change it after you do all that other stuff. make sure you have the mmsc and everything else correct for tmobile. I have mine set on lte, gsm, cdma, which seems to work for everything, voice, data, mms. Anyway, good luck and have fun! If it doesn't work, oh well, I bought mine for $13. I also have 3 other s4s, a sprint l720t, the cricket one, and the 970 us cellular. I cant get the cricket or the us cellular to take the tmobile sim, even though I flashed the radios to gsm and the roms to tmobile (pain in the a**), but I think those, although they do have the radios, don't have something else hardware wise to allow gsm, since they are both exclusively cdma. I found the sprint one, paid $10 for the cricket, and $22 for the us cellular (it was brand new though). I get lucky on ebay, people think their phones don't work and they do. I've take all of them apart many times, and most times they just need the usb,mic ribbon cable, which I can get on ebay for $1.89 (there's 2 versions though). Late
