[MOD][FIX] T-CDMA 64 instead of Verizon Wireless fix - Verizon LG G2

I have been having problems with the stupid T-CDMA 64 problem and being OCD-ish I wanted to fix it.
This zip is for the peoples who were having a hard time figuring this out..
It flashes the correct file needed to fix the Verizon Wireless banner.
I have tested it on AOSP and Stock and it seems to work just fine.
It happens whenever I use a custom kernel, try it out and see the results.

I'll revert back and take some screen-shots shortly...
but in short it would show T-CDMA 64 in a phone call or on the banner
instead of Verizon Wireless

Example would be: on the lock screen at the bottom it days Verizon wireless. On some Roms it will say T-CDMA instead.
Data works as intended, just looks different/annoying.

if you actually put "Verizon Wireless" instead of blank "" you could submit this to CM gerrit for inclusion. another note, their file includes some other content that should remain in the file, so you'd need to add your lines to theirs

Written so fly like a G2

I had the same problem. When I install the cloudy flex rom, the signal bars would say i was roaming. I tried to do *228 option 2 and it worked. But after that it would show t-cdma 64. Then I tried the mahdi rom and the same thing. I reverted back to stock, 10b first, then 11a, then 12b. Took it back to the Verizon store and they said it had the wrong prl. They put in a new sim card and everything back to normal. Also when this happened, my 4g wasn't working and I would not get all text and calls. All is working now after the new sim card. The prl version for verizon 4g lte is 15287.

Different people will have different PRLs for their geographic location.

The *228 is probably what fried your SIM card. That is not recommended with the 4g SIMs because they're already initialized when you register your device on the network. Anything you do after the fact will only create an opportunity to corrupt the SIM data.

[Q] AT&T "4G" Support/Signal Strength on V21A & V21E?

Does v21a and v21e support at&t's "4G"? Just wondering because I hear those basebands are ghost call free and I'd like to give it a shot.

4g is all dependant on your location ..its very spotty and I'm not sure but I think you have to change the flex XML which gets a little tricky bit there is a thread on here that talks about it

Yeah I know about the flex file. Aria has an entire thread on it. It just makes me wonder because v20p is the only one that gives me a good signal even though on v20c it uses the exact same baseband and signal strength is poor. Is v20p the only one with good strength?

Hahahaha I guess my phone is just borderline faulty. I hardly have good signal strength when I change the flex file and on the acid hazard rom my phone doesn't vibrate at all.
Also by poor signal, I mean it's poor after flex file changes

I have this phone on that band i was skeptical to at first because i heard
the base frequency's are what you flash for tmobile but just flashed it an hour ago and my "HSPA" is running fine :good:
A funny thing happened to me when using promethius v21e. I read it needed to mess with the flex and the apn to get 4G on my 925. So I did all of that stuff with replacing the dialer and contacts because of the force closes and I thought it was going well. But after a while it became pretty annoying the gapps would crash in the background all the time so I wiped all of the cache and reinstalled the base promethius zip v21e from my sd card. After that I didn't mess with flex or anything else and had normal att signal strength 6 mbps. I couldn't remember the apn that gives me 12 mbps off the top of my head so I just created one named it phone, and for apn I put phone and then hit save. First test of this setting gave me14.9 mbps speed test with zero change to stock flex or dialer. Running smooth and fast for 2 days.

to clarify, I only added the phone apn. I did not touch the apn for cingular that comes with promethius.
after you asked about mms I had my daughter send me one to find out. I did not get the mms until I modified my "phone" apn to apn type "default,internet" still leaving the original apn untouched. Ran another speed test seems okay.

sprint s4 metropcs mms fix

This is to fix Mms message on metropcs flashed sprint galaxy s 4 your phone most already be flashed to metropcs with working internet, Flash the zip in recovery and reboot, mms messages should work from first boot. This will last thru a factory reset.
Edit: I was ask to add some details as to wat the zips doing and wat I do. I edit the mms-config.xml in the stock Mms.apk/SecMms.apk to settings from verizon which work for metropcs, I also use an apns-conf.xml that I edited for metropcs. the zip will mount data and mount system, it will delete Mms.apk/SecMms.apk and Mms.odex/SecMms.odex, it will delete dalvik-cache for Mms.apk/SecMms.apk, it will delete the telephony.db file in /data/data/com.android.providers.telephony/databases/ which countains apns. it will replace Mms.apk/SecMms.apk with the one I edited for metropcs it also replaces the apns-conf.xml in /system/etc/ which countains the default apns for the one I edited for metropcs (on first boot the phone will create a new telephony.db with the default apns countained in this apns-conf.xml, that is why this fix lasts thru a datawipe/factory reset). For more details take a look at the updater-script.
for the 4.3 script, flash the zip - reboot to system. Then open dialer and dial ##3282# hit edit enter spc then go to more then lte apn settings and click the circle on the right of the global roaming apn to activate it then hit home and all should be good
if you have issue where messaging app has default android icon use root explorer go to /system/app long press on SecMms.apk select move hit back hit back again go to /sdcard and paste SecMms.apk on sdcard, it should now show the up on sdcard with normal icon long press on SecMms.apk select move hit back go to /system/app and paste SecMms.apk back in /system/app and reboot phone should now show normal messaging icon
I am not responseable for anything that happens

Hang on...I must clarify. As much as I love to profit off of Metro flashes, we need to get the facts straight.
Flashed phones to Metro will not work nationwide. Boost will. Metro has better talk & text in their coverage area, but their data can either be equal to or slightly slower then Boost (depends what time of the day you're on the network). We also JUST got 3g here in the Tampa Bay area, and we're a huge market, go figure.

ive had very good luck though if i may say so myself. i have traveled to florida new york san francisco and alabama and gotten very good coverage on my flashed s3 from verizon and im suing the 3033 prl in atlanta. its faster than i could have hoped for. i have heard though before that flashed phones do not work well outside of the state theyre flashed in but aside form that metro itself has bigger coverage than boost and sprint. and now they are merging with t-mobile although im still not sure how thats working out because theyre rolling out city by city certain thing such as hartford dallas baltimore and i think boston.

interesting. almost a year ago we had 3g coverage over here in saint pete, i had to use a special prl on my step brothers admire 3g to get it to load up right though.
now a days its all lte anyways so no one uses 3g
Then you would have been the first. I've been flashing in this area for over 2 years at least, and none of my fellow flashers in the area got 3g besides 1 tower near University Mall.
Can you tell us about this special prl?

[Q] No 4G LTE after SIM error

Hey guys,
I work at Sprint and my technicians and myself cannot figure this out. So I thought I would reach out to you guys!
I had 4G flawlessly on my phone for the first few weeks I had it. One day I got a SIM error that read something like this, "No SIM Card: 4G LTE will not work as SIM/UICC is reinserted". I popped out the little SIM card, wiped it off, and the phone read it and the error went away. Since then I have not had a single connection to 4G LTE.
All of our demo phones are on 4G lte as well as my girlfriends phone at home. I am constantly in 3G or 1X. Any advice would be great
Things I have already tried....
1. Updated profile/prl
2. Reprovisioned phone using ##72786#
3. Toggled settings using *#*#4636#*#*
4. Wiped and installed a new ROM
5. Played around with SIM card slot and rebooting phone
I am going to try a new UICC sim if we have one around the store...if that doesn't work im out of ideas!
I have no suggestions, but I have had the same exact problem the past couple of weeks. I got the error, but I didn't even pop the SIM card out. I just put the phone in airplane mode like I usually did when I got the error. When I took it out of airplane mode, my 4g was gone and it has not come back. I have checked all settings and I can't come up with anything. I also RUU'd back to stock just to make sure. Still no sign of 4g.
Let me know if replacing your sim does the trick, because this has been driving me crazy.
By the way, I know it is the phone and not just sprint messing with the towers or something, because my wife's evo 4g lte is on 4g all the time.

I read somewhere that your SIM ID and your UICC ID have to match, don't know if it's true, but go to settings - about - phone identity to check it out

The phone is rooted. I don't think there are any other radios out for this device yet though. Thanks for your reply though
I'm a Sprint Tech and do not have an answer currently for you guys as I have been receiving this error as well and only just found this thread. Will try to research tomorrow and see if I can find an answer. I only received this message once as of yesterday and it went away seconds later. Tonight it reappeared and is sticking. Under app info it shows this is the Phone app that is sending out this notification. There is a possibility if you force close the app and then disable notifications for it that this error may go away; however, I'm not sure what other notifications we would consequently loose. Current corporate PRL is 55015 and I am running Viper 1.0.3 with stock kernel. I am wondering if this has to do with refreshing your PRL because I did not notice it until I requested it from Updates two days ago even though the actual PRL version number did not change.

yea that sh!t didnt work at all. this seems really stupid to me that our phone is having this issue what could be causing this why would the sim card mess it up?
Ok so the consensus is, this seems really stupid too but its the only thing I can figure, the SIM is loose. If you eject your HTC One Micro Sim and place a small piece of scotch tape on the reverse side of the connector, this gives the card just enough volume, when reinserted to consistently maintain contact with the reader as the SIM tray is simply too big and is allowing the phone to believe there is actually no SIM card inserted when the connection is detected as broken. Suppose this also explains the inconsistencies in various user experiences since we all have different handling habits. Any one else want to wager to guess why this problem is so intermittent?

my friend who works at bb hooked me up with another sim. im taking it to sprint tomorrow and see if they can do anything. my friend said he could swap for a new htc one as well. i would have to pay 30 bones though.

Left nexus 4 to come back the atrix hd. I'm on tmobile.

So my question is, and correct me if I'm wrong. But, I can still unlock the att atrix HD to be used on tmobile , correct? Reason for leaving the nexus 4 is the eb40 battery. I had the atrix HD a few months back that had the eb40 in it and got 7 hours of actual screen time with 30 hours between charges. That alone is good enough of a reason.

It would ask me for my unlock code every now and then but LiquidSmooth working powerfully and perfectly! I paid 20 bucks for my unlock code and had it within 2 to 3 hours. No signal nor lte problems although i prefer h+ on T-Mobile due to lte being a batt hog

YUP. Welcome to the Matrix HD T-mo club.
After unlocking, make sure you set the fast.t-mobile.com apn which gives you access to LTE.
Otherwise if you're in an lte area, you'll have no access to internet (the 4g lte icon will be shown but cant turn on).
Mexica retail will allow you to manually select between 4g/3g/2g modes if youre feeling like saving battery/MB
I got LTE 13 on T-Mobile with stock rom and epc.T-Mobile.com apn

Looks like I'll be using the mexico ROM. Apparently there are no custom kernels for this thing yet? Or am I missing something?

There are, but they're for the 4.2.2 custom roms. Without an actual kernel dev working on this device making a custom stock kernel, the best we could do is add in a few patches to the stock for CPU/GPU overclocking, some IO schedulers, and maybe some of the patches used by the dev team. I've even thought about doing a full merge of the dev team kernel and our stock JB kernel just because I can, don't know what that'll do or if it would even boot.
What's included with the mexico ROM? I'm assuming the barebones stock kernel.

Roam Control 2.9.2 has been released!!! 11-28-2013 UPDATE

EDIT: 2.9.2 is now available which should fix roam control not working after the MJA update.
There is a brief delay before it roams so give it a change to do its thing.
MrGreg has released Roam Control 2.9.1 which adds support for our Galaxy S4.
What does this mean?
for those of you who have bad data or coverage you can pair this up with an appropriate PRL and get better voice / data coverage!
Here is a LINK to the website where you can get the app.
Please be sure to click HERE and find a thread to thank MrGreg in as he is usually inactive on XDA.
Enjoy!

Thank you SO much for this update. You made my freakn day!! Verizon has full bars LTE on my block, where as Sprint literally doesn't have any service what so ever, I roam on Verizon 95% of the time (but I have an AirRave at the house, but before the AirRave that is what would happen!). But also even 5-10 minutes outside of my block I get horrible service. I bought Roam Control on my GS3 and now I get to use it on my GS4 too, thank God!!!!!!!!!!!!!!
Still not working here. It gets su and does nothing. Stock rooted MDL with newest ktoonz Kernel.
Edit. Reboot and works like a champ
besides its stuck on roaming even after mdc back to stock??
Well I had to use the dialer code to re activate my phone so wierd. Any one else have this issue?
Does not work for me. Switching does abolutely nothing.

Yup. Nothing at all. No change after a reboot either. I emailed the dev, hopefully I get a quick response.

Well the force roam worked... obviously lol, it was just stuck there no matter what I did! I hadda re-activate my phone using the dialer code. Simple fix, guess I'll deal with that for now, like you said, it's a simple 2 minute fix.

I believe people are having problems with the mdl and above firmware update. The mdc firmware was the one that you could easily rewrite the prl if I remember correctly. I am going to try rolling back to mdc then test roam control and see where I get.
