After i flashed the Starburst v1.7 I have no 3G? Speed tests are: Ping 1910ms, Down-15kbps up-51kbps
I've been getting those speeds during the evening ever since the 4s went on sale.
If you know your msl, dial ##debug#, enter the msl, click evdo and look at the bottom at the AN-AAA. If it says pass then that means you are authenticated. Probably means Sprint is slow.
mine says none
How do I authenticate?

AN-AAA says "none" Anyone know how to get my 3G back working?

Never saw none before. It should be pass or fail. Did you do an ESN repair on this phone and forget to program your account name and passwords? If not, Odin a stock firmware.
You could try to dial ##72786#, which will erase everything and you will need to reprovision your phone. Going to the sprint site and swapping phones and swapping back and reprovisioning could help.
You could always punt and flash back to stock and seek help at a sprint store. Look up DYI USB jig so you can reset the Odin counter. It's a micro USB adapter and a 301kohm resistor jumpered across two pins.
Mine says Fail next to AN-AAA.. I'm on Starbust 1.8 and Stock Pulled w/CWM kernel. Guess I'll flash back to stock and see what it says. But I never had great 3G (or 4G) before this ROM either.

Flashing back may not fix it, it's a provisioning issue. Try system/about phone/ updates/update provision. You may have to call sprint or go to a store. It is fixable. I just had a similar problem but for a different reason.
i would wipe data and cache format system n wipe dalvik n reinstall 1.8
Another thing you can look at is dialing ##data#, select edit, select white box and enter msl. Select data profile.
Username should be your sprint email address. [email protected]
Device ip 0.0.0.0
Primary ha ip 255.255.255.255
Secondary 68.28.57.76 (at least on my phone)
Ha password is secret (yes the word secret in lower case). This is used to setup the encryption for the key exchange. This hidden and you can not see it.
Aaa password is used actually to login to the network. It is phone specific and changes every time your phone is provisioned. It is hidden also. I would not change the aaa password change unless you know it. You probably need todo a hex dump to get this, newer phones prevent QPST, qxdm or CDMA workshop from seeing it.
If the first 4 items I mentioned are different try the above values. Avoid changing the the last two I mentioned.
There are a couple other things you can check with QPST and CDMA workshop but if you are not doing anything illegal, normal provisioning would fix them.
Last night (in bed), I did a nand backup and then the following and check AN-AAA after each...
1. Restored my stock rom nand (includes LostKernel). AN-AAA passed.
2. Factory Reset, installed fresh Starburst 1.8. AN-AAA passed.
3. Installed StockCWM5 kernel AN-AAA passed.
4. Restored by backup from above (SB1.8 w/StockCWM5). AN-AAA failed.
5. Format system and re-installed Starburst 1.8, AN-AAA Passed
So, just re-installing Starburst 1.8 seemed to fix it.
Still had AN-AAA Passed this morning after getting to work (we have bad signal here) and 3G was working at about 300kpbs. However, I just checked again and it say's failed again and 3G is not working. Will look at it when I leave the building.
gedster314, those settings looked the same for me, except the 3rd octet of the secondary address was different. It was 177.
Followup to last post...
I left the building where I should have better 3G signal. Still showed "failed" on AN-AAA. Tried several things.. rebooted, wiped dalvik, wiped cache, resintalled SB1.8, then all those things together with a /system format. Nothing helped, still said "Failed". By this time, I had reached where I was to have lunch, which incidentally is in a VERY good signal area (I635 & MacArthur near Dallas).
Even though AN-AAA still showed failed, I did a speed test on 3G and got back 1115kbps down and 600kpbs up. That's the best 3G speeds I've ever seen on this phone. That area also gives me about 12000kpbs down on 4G. (everywhere else I get about 1/5 to 1/10 of those speeds).
So, I don't see how 3G reception is at all dependant on AN-AAA pass/fail.
Now after starburst 1.8 install im getting LOS for the first time and still crap internet speeds. Guess I'm bailing on this rom. Can't seem to get any help on the strarburst thread.

Ok, so I updated my s3 to 4.1.1 but after a week of using the update, I still hadn't seen any sign of the expandable notification options. So I decided to re-install the update by flashing via Odin, which I did. After the flash, the expandable notifications still weren't available, so I instead flashed the stock firmware, hoping to update from stock and see if the problem was fixed. Unfortunately when I rebooted after the stock install, my phone would no longer connect to data, or even to the network period. I can't text, make calls, or connect to data. It shows full bars but when I try to do anything it tells me the network is unavailable.
I tried a lot of options for fixing it:
-I checked all my network settings. Data was on, I switched into and out of airplane mode, no luck.
-I tried to set my network operator by manually selecting tmobile. No luck.
-I tried re-entering T-Mobile's APN settings. No luck.
-I tried to restore from a backup I made of my 4.1.1 when it was first updated. No luck.
-I tried flashing multiple versions of stock firmware, as well as cm10. No luck.
-I checked my IMEI, it's correct.
-I flashed a few different modems. No luck.
I've run out of ideas and I can't find any other ideas in the forums. The closest I have come to getting a fix was during one instance when I was flashing stock again, I cleared my cache, dalvik cache, and did a factory reset as well as formatting my internal storage. When it did the first boot it had service for about thirty seconds. I was able to receive a few waiting text messages, and I had edge data for the remainder of the 30 second or so period. Then I lost data again. Every time I boot a notification ticks on my status bar that says "Restricted Access Changed" and before I can pull down and tap it, the notification is gone. When I try to set a Network Operator, it says something along the lines of "Unable to connect, not registered on the network." I'm stumped.
Has anybody else had this problem, and does anybody know how to fix it?
Just a guess, but perhaps T-Mobile has blocked your IMEI? Did you buy the phone off of someone or straight from T-Mobile?
Did you ever report it lost or stolen?
Only thing I can think of given your scenario.

I bought it through Costco as an authorized upgrade offer by T-Mobile. I can't imagine any reason why my IMEI would be blocked. I went to the t-mobile store yesterday and they told me that it should be working and that I should take it back to Costco and see if they can do anything for me in terms of replacement.
Problem Solved!
Apparently it was because when I got my phone they didn't give me the upgraded sim, they just cut my current one to fit the microsim slot. Go figure. This could have been solved by tmobile last night if the guy hadn't refused to help me just because I had rom manager installed on my phone. Just because I have a root program installed on my phone doesn't mean my phone got messed up playing around with root. Anyways, i updated my sim card through tmobile's phone service and I'm a happy camper now!
I used to have working data from Pageplus with most of the stock roms & cm7.2, but since the day I moved to Cm9 onward to cm10.1... Data is not working anymore!
I tried multiple APNS programs like "APN Backup & Restore", "HiAPN" and converted them into system apps.
Flashed Epic4G_alt_carrier_data_fix.zip also but still no data.
But nothing changed and the spotty 3G icon on top shows from time to time, but it has no use other than draining my battery... any ideas???
Okay it turns out I missed up something while I was playing with qpst/workshop/dfs, and because of it the data totally stopped from working on all of the Stock and Cyanogen roms that I have installed and tried, so it's not only CM10 as I had thought before...
So I tried to copy the earlier settings for those programs from just looking the screenshots that I had taken of qpst, or even copy the settings directly from a Verizon Motorola Devour that I have, but that didn't help either!.
So I went a head and used the last option that I had... "Odin3 v1.81" to be exact and back to stock (Odexed-Rooted-CWM-Busybox-EH06 leak.tar) with the option "Phone EFS Clear" Checked. as a full hard reset.
After the hard reset, my phone booted fine to the newly installed stock rom, but I found out that my phone didn't lose all the data that I had played with in qpst only, but I also lost my Pageplus service on this phone!!!. So my Epic went back as just as a fresh sprint phone from the factory (all this happened because I checked the odin setting "Phone EFS Clear") .
To fix this I tried to dial Pageplus reprogramming number *28900, but it directs me to sprint activation instead!..
Thankfully I remembered that I had backed up qbst settings earlier before I use odin, so I went a head and loaded it up to my phone. The Pageplus service came back, but every time I try to make a call I hear an automated message from Verizon that says ""there was an error in processing your call". reprogramming again with pageplus number here didn't work either...
So I went to Pageplus website and sent a support ticket, and they replied within few hours suggesting to reprogram the phone again but with the data turned off this time. I followed the instruction and this time it worked and my phone can make phone calls again! and now I have my Pageplus service back with the data working finally on CM10.1... phew~
I picked up a Sprint prepaid HTC 816 recently and decided to flash this rom below
[ROM][UNOFFICIAL][CM12.1][5.1.1][VirginMobileUS][A5][single sim][1/1/2016 security]
That one
It installed great, had everything everything working after I added my Sprint APN settings. The phone still displayed it as Virgin Mobile and only 3g seemed to be working. But I was making and receiving calls, text messages and had mobile data.
Fast forward a couple of hours, I installed a custom theme from the Play store, rebooted and ever since then I lost the ability to pickup a network signal and access my APN settings.
If I re-seat the sim and toggle airplane mode it will pickup a network signal and I can regain apn setting access again but it drops within minutes.
Ive reflashed the rom, wiped everything reflashed again, same thing. Any ideas on what has happened?
Thanks and appreciate your time!

Are these the APN codes you used(poster corrected a mistake in green text)? Looks like there is a different APN for prepaid /postpaid.
http://androidforums.com/threads/working-sprint-prepaid-apn-settings.920752/
I indeed use the apn settings in the green from that post. They were working fine until I had a reboot. Then everything went to ****. It wont even let me access the apn settings and when I can its briefly and then I lose signal and apn access.

I had an issue with something on my Virgin mobile 816 a5_chl a while back and a member @wxppro was very knowledgeable about APN settings and their intricacies. He had a MVNO 816 at the time with an APN issue and I bet he could help you with this as that was my best suggestion for a fix and it didn't help you.
See if you can direct him here to this forum so that if he can help out the info is here to help others as well. Good luck.
Not sure how much I can help. APN is a tricky business. If your APN settings disappear after some time, it is generally because the cellular network the phone connects to does not match the APN's MCC/MNC numbers. Or it could be the phone is in 3G mode (CDMA EvDo mode).
You can try these things:
Switch network types, from LTE to 3G, wait a minute, and then back to LTE. APNs do not show up in 3G mode. They only show up in LTE (or global) mode.
When you have the APNs show up, check the parameters are correct, you can do a "Restore to default" and then add the new one following that post.
Hope this helps.
I'm having a similar issue as well (except on virgin mobile)
A month ago I flashed squid's version of CM 13 on my phone and everything was fine for a few days, until I completely lost LTE and access to APNs. I reverted to stock and still was unable to get LTE, although I could get a shaky 3g connection if I changed the network mode to CDMA only. I called virgin mobile and they walked me through the troubleshooting steps and eventually determined it was a network outage (even though two desires in my house belonging to other family members had LTE). I called again after they verified that the network was working again and they were still unable to fix the issue.
Recently, a friend upgraded from a desire to a different phone on a different network, and gave me his old phone. I plugged in my sim card and activated this new phone and I got LTE. Figuring everything was good, I decided to flash squid's ROM once again. The same issue happened, I got LTE for a day or two until it cut out service again. No access to APNs, not even any service in stock or on the official build of CM12 with the APN fix (I can't access APNs there either). I'm out of ideas and would appreciate if anyone had any input on my issues.

I have this same phone a5_chl Virgin Mobile. Did you factory reset your device before flashing back to your stock rom? The other thing is and this is just my opinion not a statement of fact or a knock on the wonderful Bigsupersquid but that 13 CM ROM is nowhere close to being stable enough for me to risk flashing it to my daily driver phone. Just read all the posts and his candid responses. You were basically a beta tester .
I'm not an expert in APN's but if you can't get that fixed your last resort might have to be wiping your system and then flashing or running the executable RUU (rom utility upgrade) file found for our device on HTC/downloads . This is a last resort option and wiping your system will remove your existing firmware so have the correct RUU for your phone downloaded to your computer before attempting a wipe. If it's an exe, which I believe the U.S. Virgin Mobile one is ,you will hook up your phone fully charged in fastboot mode then from your computer run the exe RUU like any other exe executable program and wait. It will reformat all partitions and reinstall pure stock ROM. Hope someone else had an easier fix for your data issues and good luck.
EDIT: you will need your stock recovery flashed back and a relocked bootloader before flashing the RUU but I've read that some have flashed their RUU over a custom recovery with a locked bootloader and it wrote over the custom recovery with the stock recovery. I have never personally tried this just the first way I mentioned and that worked for me.

I did try factory resetting and I am on stock after flashing the RUU. It makes no sense as the RUU should have reset everything. That perplexes me the most

OK then you did get back to stock not from a nandroid backup but from flashing or running exe stock RUU? If that's the case then it replaced everything that might have been changed and your issues shouldn't be related to any APN changes. You also removed and reinserted your sim card as I believe, correct?

i posted about my lte issues i had for nearly two weeks, running stock just to verify the data service problem wasn't my rom...
i had to install stock recovery, relock bootloader, download the ruu.exe from htc and extract the .img file in Wine, then rename it onto the sdcard and reboot into hboot so it'd flash. neither Wine nor virtualbox xp talk correctly to any of my phones over usb. and i wasn't about to native install Windoze.
factory reset stock didn't fix it, even trying activation, update profile, etc.
i learned i could get 3g data but switching to lte instead of cdma shut down data entirely.
virgin eventually directly escalated me to tier 2 tech support in my last call, they sent a couple service programming pushes to the phone that got my lte back online.
i tried the various service programming menu options repeatedly, with no results but the prl updated once; but the trigger to fix my lte seemed to come from upstream.
i tried various apns, in cm12, cm13, and stock lollipop. rebuilt init_a5.cpp with different mccmnc and adjusted apns. i really tried most tricks in the book plus a few more.
as far as alpha testing goes, at this point I'm just sharing something cool... i always enjoyed flashing latest greatest on my ov way before i was building.
not too many actual logs to really bug report for either rom.

Some of that was over my head but happily not all of it. Basically what your saying is the fix needs to come from the carrier and it's a reset issue on their end not a custom rom issue? By the way I'm a big fan of your work. Hell I might be on one of your older ROMs right now I've flashed so many I forget. Thanks for the education.

The first time it happened, I flashed back to stock using the RUU.exe. I tried again but the second time I took out the SIM card before running the program, I still can't get LTE.

It does sound a lot like a carrier/account issue as I managed to kill 2 different 816s. I don't think it's the SIM card itself because I put it into a 3rd phone and got LTE, although since it was someone else's phone, I didn' t bother activating it.
I guess you got lucky with support, I tried talking to them and they tried the same thing with me. Although all I got was excuses saying they're logging a ticket with their "network engineers" and to call back in a few days. This continued on for a few weeks until they determined I needed a new phone, which I was also bounced around for another few weeks (I still don't have it).
I'm just completely lost now. I'm almost certain it's my account and it needs to be reset, but I can't get a tech who can help me. How did you manage to get someone in tier 2?

This is starting to scare me as well because I'm thinking of going back to stock once Marshmallow gets pushed to our phone to get my beats drivers back and this is making me think twice. Sorry your having so much trouble.

seemed that way.
i took radio logs before and after it worked, and worked only on 3g, and it looked to me like the sim card responded differently to the ril after things were running right again.
mine might've been a special case, though, it came from ebay with no sim, and virgin had to go to a little effort to get it programmed when i installed the sim initially.
they also claimed for several days that the local Sprint tower was down for lte service.

tier 2 takes luck, time, many calls, and eventually you learn the answers to all the questions tier 1 outsourced from India asks so you can feed it to them so fast they want to shuffle you along. takes a couple of weeks to over a month to get to tier 2 and sometimes they have to be involved multiple times as well.
I've been dealing with virgin since 2009... replaced only two phones, eventually got the rest of the issues hammered out with persistence.
for a little while, twice, i had direct toll free numbers to American tier two even because my issues were so hard to solve. it didn't take too long for those numbers to be disconnected, though.
Hello, so here is my problem. I have been using Cyanogenmod 13 on my LG G3/ls990 for months now. Recently I needed a static IP address through Sprint. When they applied the static IP to my account, I was stuck on 3G, even though I mostly have LTE. Basically what I did was use an old stock rom backup to update my PRL/Profile. This brought back my LTE service. Then I reloaded my CM13 backup. Unfortunately, at first it didn't recognize my sim card, and then it only recognized 3G. Okay, so no problem, I decided I would just go back to the stock rom and clean install a new custom rom. Unfortunately, when I went back to the stock rom, it was also stuck on 3G and this time when I tried to update the PRL/Profile it didn't work, I am guessing because it already saw these as updated. So after a few chats with Sprint's tech support, I was able to get LTE to work again. She said a particular network configuration file wasn't working right, and she did something which was suppose to fix it. As instructed, I typed in code ##72786# after she did it, and LTE worked perfectly. Stupidly, I thought it would be as simple as reloading my CM13 backup. Yet it did it again when I loaded the backup, and now I am stuck on 3G again. Before this I didn't really connect the two together. Does anyone know what exactly is happening here? Tomorrow I plan to call Sprint again, to get them to fix the file, but is there a way I can do it myself, in case I have this problem again when I install a new custom rom? For example, if I go into ##Data# will I fix things by changing a setting in there or something? I hate having to talk to Sprint every time this messes up, and yeah, I know it was stupid of me to do the same thing twice, but it was a day apart and I forgot what I had done the first time. Hopefully whomever I talk to tomorrow can figure out what the woman I spoke with did, because she definitely knew what she was doing. Thank you for all of your help!
Update: Called Sprint they reset my network and I have LTE again. I am somewhat wary of installing a new rom but would like one for resolving performance issues and wifi tether. I downloaded an unofficial Lineage 15 Rom yesterday while I was on 3g only, but it couldn't find my sim. Is there a way to backup my current network settings?
Update 2: So I just tried a fresh install of Lineage 15 and it didn't work. First it recognized cell but no data. Then I went into data settings chose carrier settings that crashed, "android.com. [something]has stopped working" , the sim was unrecognizable after that and the carrier settings weren't there any longer. I backed up my EFS partition in the stock rom before installing, but then I was stuck on 3g even despite that. I called Sprint again, and got them to reset my network settings. Don't want to keep calling them though.
Anybody here with Sprint and a static IP that can recommend a ROM that will work and not mess up my network settings? I don't care if it is Marshmallow or Nougant, I just want something that doesn't overheat my phone and which I can have native tethering.
EDIT: I was able to install Fullmics and retain my LTE.
