I currently flashed and activated the Epic 4g (Sph-D700) on the cricket network, and everything was working good. But stupidly I flashed the Cyanogenmod 7 RC3 for the Epic 4g on Sprint network thinking the 3g would work. But ever since then I could never get the 3g working anymore.
Tried many steps; from QPST, APN settings, returning to stock, flashing CM9 Beta 4 on cricket, CM7 for Cricket, trying many ways in many forums to fix 3g, and returning to Cyanognemod 7 RC3 on Sprint and trying to fix it from there.
don't know what to do anymore. I installed an app like root explorer for free and messed with the apn. Tried to mess with the hap secret going to system, etc and reaching ppp. Tried installing the epic 4g different cell phone company fix flash file, the i905 data fix and no luck. I tried using CDMA workshop and QPST and tried a bunch of PRLs and the 3g icon wouldn't even pop up.
The PRL that worked with 3g cricket was 42700 one. Flash cyanogenmod 7 screwed it up. I even used voice dials to open APN and nothing. Even dialed ##8778# and set it back to PDA. Tried dialing #data and mess the settings there. Does anyone have a back up of the apn settings on cricket where the 3g works? I currently have thr $55 plan .
I noticed that on cm7 and cm9 the connection goes to 1x and no 3g connection. Also noticed that I keep losing signal and sounds like its updating PRL.
If anyone can help, please

I've did the QPST setting changes do it and I have Talk Text and 1X internet working but 3G and MMS still remain a mystery to me even though I've changed the APNs on this sucker.
Another thing to note is that when I edit the PPP AN username, it reverts back to the sprint username instead of the one I edited it to cricket. The UM actually sticks but not the AN.
been trying to figure this out for a while. Then I may just dump this rom so no one else has to bother with such a hassle
Any progress yet I'm trying to find the info on doing the same?
I have made progress, I'm down to just figuring out how to fix video play on 3G and mms settings. I do have 3G working now and it's pretty fast on the cricket network, about the same speed as using my 7Mbps (or mbps, I forgot which) DSL internet. 513kb download and 533kb upload.
Do you know how to make a backup of a rom on these 8600? I can't seem to update from 2.1 without it being hooked up to a sprint network or something. And the two roms I found on the internet 2.1 and 2.2 are not doing it, because the 2.2 has issues reading the NVRAM info and the 2.1 has problems with the camera feature on the phone (the camera just stops working...)
I'm gonna post a guide to this once I figure this out, I think this phone deserves it since no material is on the internet for it. If someone google searchs this and finds this post, can you please help me with backuping up my rom? xD
I've got 3G working good but any ideas as to what's still causing mms to not work? I've unpacked the Mms.apk and saw no references to the provider in it and I took a look in telephony.db and saw that the APN settings were correct for cricket. Any other files that affect mms settings on sprint phones (or androids in general?)

hey how did u get the 3g to stick in qpst an settings i have been tryin for along time to get it to stick
I just updated to the 9/7 official nightly and messed with some settings (trying to get mms working).
Right now, if I set myself into 3g mode, I don't get any data. 4g still works.
I was doing the old mms fix where I changed the CDMA subscription to NV from RUIM/SIM and back. I still have a phone number and an IMEI, but if I switch to CDMA mode, no data.
I prefer to use 3g for battery savings, and also, I don't always get 4g coverage, so it would be nice to fix. Any ideas?
I'm not sure if it was the flash or the messing-around that caused the problem because right after flashing I was on WiFi and didn't notice if 3g still worked.
I am running CM12 on the Desire 816 from Virgin Mobile. I can use 3G and recieve calls and SMS messages. 4G doesn't work at all. I've tried going to the secret menu and trying all the different mobile network options that have LTE in the name and no dice. I've tried flashing this and when I do that I don't get a data connection at all. I really don't know what to do here. It was working fine on CM12 until I had to reset my phone yesterday.

You need to edit a certain APN file in the system directory. I'm not sure which one, as I'm stuck on Kitkat, but maybe that will help your research.
So the issue I have is I no longer have 4G. I got off an airplane and my phone had no 3G or 4G service. If I rebooted my phone or turned airplane mode off and on I would get 4G service for about 2 mins before it would switch back to 1x. Below is what I have done to try and fix the problem. Any ideas on what else I can do.
Reloaded a nightly of CM11. Did not fix anything.
Used odin to load a stock TW 4.04 rom. (still no 3g or 4g service)
Noticed that my IMEI had been earased to 0. I went to a verizon store to check my SIM card and noticed it was gone.
Used MTK NVram to restore my IMEI. (Still no 3g or 4g service)
Used the terminal command SU REBOOT NVrestore (This gave me back 3g service but I still do not have 4G service.)
I've search everywhere and cannot find a solution. Any help would be appreciated. I currently switch between CM11 and TW4.4 rom. Neither connect and preferred network is set to LTE, switching to global makes no change.
Thanks
I have been using the CM13 nightlies for a few days now, and all I can say is wow - I love it! Phone is super fast, no more constant freezing and restarting (when I was on MOAR rom).
Only problem I've had so far is that I cannot connect to 4G LTE network. I have Boost Mobile and the default Boost APN seems to work fine, I can connect to 3G if I set the preferred network type to 3G, but when I set it to LTE I get neither 3G or 4G LTE. I do not know whether I should be using NV or RUIM/SIM in CDMA subscription (and couldn't figure it out through googling either) but it seems that I cannot change it to RUIM/SIM, no matter how many times I click the option it just stays on NV. Also, trying to open carrier settings just crashes settings "com.android.phone has stopped"
SIM status shows network state as disconnected when I have LTE or Global chosen as preferred network state.
I started out with the unofficial CM13 build, then from there upgraded to the 20160716 official nightly and then the 20160720 nightly.
I then flashed a stock 6.0 rom I found here and that let me connect to 4G with no problems whatsoever. While in this rom, I updated my PRL just in case. I then flashed back the 20160720 official nightly, and same thing. Still no dice.
TL;DR anyone have 4g working on boost with cm13
update:
found this flashable zip through google, flashed it in TWRP and LTE has worked like a charm ever since. :good:
