[Q] 4G wont connect, just scans then says DISCONNECTED - EVO 4G Q&A, Help & Troubleshooting

I installed the Synergy custom rom with God Mode and my Wimax isnt working, it says scanning then disconnected 1-2 seconds later. I checked my wimax keys and it says they are present, I updated my profile and prl but it still doesn't work. I have a nandroid back up if that is nessesary.
any help is appreciated!

Mine sometimes goes out too but I just reboot and it works again. Although once it didn't work so I wiped and reflashed the wimax zip and it came back.

I would give it a day, sometimes sprints network will go out. If it doesnt work tomorrow, reflash a stock rom backup and try that.

Wipe and flash it again. It works for me.

Issues connecting to 4g/Wimax

I partially solved my issue in another thread, but still cannot connect to 4g. I had initially thought my RSA key was gone, but was able to find it in an old nandroid and reflash it. KeyChecker now says my Key is Ok. I verified my MAC address is correct and have flashed the most recent wimax radio. I have also updated my profile and prl. However, I still cannot connect to 4G. I was in Minneapolis in a strong 4g area and turned on the 4g. It turns on, scans, says connecting to sprint, and then quickly returns back to scanning, finds sprint, tries to connect, then scans again. I tried this is multiple spots all over the city but still couldn't connect. I am running Fresh 3.5 with the stock kernel and have connected to 4g in the past prior to temporarily losing my keys. I have flashed different sense and aosp roms with the same result. Someone please help! I am stuck! I would like avoid unrooting if at all possible, but will if that is a last resort.
I would call Sprint tech support and see if they could do anything from their end. You can try changing kernels or flashing a rooted stock rom to see if the problem gets corrected. For a rooted stock rom, download this and flash from recovery after doing a full wipe. Make a nandroid backup of your current setup first.

OK, Sprint was no help. As of now, my wimax key is intact and Mac address correct. If I am on Fresh rom 3.5 and turn on 4g in a solid 4g area, it turns on, scans, finds Sprint, then disconnects, over and over, never really connecting. Any other Rom I have tried, both sense and aosp, 4g won't even turn on, it just gets stuck at "turning on". I have also tried different kernels. I don't know what else to do. I upgraded my radios and profiles, would downgrading do anything?

I'm experiencing the same problem as you. Every since yesterday afternoon, I can't connect to 4G. It scans...connecting to Sprint.....scanning..etc. I never lost my keys though.

Same exact thing here. Took me hours to figure it out but here's what I did..total pain in the arse! I basically updated radios in succession. I loaded an old Sprintlovers PC36IMG.zip that had all the old radios (pri 1.77). After that I updated radios again, pri 1.90. Loaded up my Dark EVO 2.2 ROM, made sure 4G was working. Then while in recovery I flashed Caulkins .zip with all of the newest radios, loaded CM7, loaded GAPPS and BAM...everything is working great....total pain and probably a lot of unnecessary steps, but it worked!
As an update, I ran wimax_ mtd in terminal and it ran through fine, everything passed and was OK, except next to "check firmware file" it says not match and next to "verify app fireware key" it says not match. Any ideas what that means?? Can you give me exact details with file links to how you fixed yours?

No 3G or 4G - 1x only - No Nandroid Backup HELP!

So my friend rooted his Evo with Unrevoked. I verified s-off.
He copied a PC36IMG onto his SD which turns out was some 2.1 rooted stock ROM. After doing that his phone could not make/receive calls/text or connect to 1x/3G/4G. Basically an expensive phone that has no phone functions. Everything else works (WiFi included). He flashed http://link.geekfor.me/rootedromzip onto his phone from http://forum.androidcentral.com/htc...vo-install-clockwork-recovery.html#post165998.
When I looked at it, he still did not have a custom recovery so I flashed Amon RA PC36IMG. Full factory wiped data/cache/dvalik. Flashed Synergy RC1. Phone still could not make/receive calls and was getting Error 16 when trying to call. Called Sprint and they reprovisioned phone and fixed calls and texting. Noticed his phone is stuck on 1x and cannot connect to 3G when my phone next to his works fine. Did not test 4G yet since I have poor 4G coverage in my area. Cannot update his profile - just sits there like something is happening but it never completes.
What are his options here? Is it a bad radio or something that we can fix? Can we flash a stock rooted ROM and regain 3G? Remember, no nandroid was made unfortunately.
I would try flashing the latest radios just to be sure. And tell your friend to always make a nandroid backup to avoid this problem in the future.
Well his first time flashing. I think he mistakenly thought the PC36IMG as a custom recovery but it was actually an entire ROM.
Didn't have a chance to nandroid. I'm instructing him how to update newest radio combo and seeing what happens.
Update: Flashed latest combo radio. Updated profile and PRL. Still stuck on 1x even after reboot. Is he hosed? Does Sprint have to do something on their end to fix his EVDO? 4G isn't working either by the way.
Update 2: Wimax Keys Checker - https://market.android.com/details?id=com.joeykrim.wimaxkeys says that RSA Key is present. Relieved that he didn't lose his RSA key. Just can't figure for the life of me why he can't connect to 3G or 4G. Not sure where to go from here? Maybe trying to flashing latest stock rooted RUU? http://forum.xda-developers.com/showthread.php?t=1110733
Bumping for some attention.
Hey, happened to me a couple of times, it will come back. Maybe wipe everything again, have you tried ##data# and entering msl key, wait... Have you updated his data profile in settings

Ok, was on the road when I had wife reply...lol.. When you rebooted the phone,did you wipe cache,and dalvik. Then try updating profile? It sounds weird,but has worked for me,without even updating profile. I have had no coverage before after flashing a Rom,also,did just that,and it came back. If rsa keys are present,that is good. If you would be kind enough to reply,whether fixed or not,would appreciate it,anyway,gonna move on...

Did he try updating his profile & prl
Sent from my criffvo
Updating profile and PRL doesn't work. It keeps attempting to update but it is never successful.
I haven't had a chance to get his phone to just try reflashing a new ROM or stock ROM to see what will happen though.
He says using ##data# and entering his MSL code and changing EVDO to automatic doesn't work either.

I would start over again ... wipe completely with Calkulin's "fomat all" zip and flash a rooted stock rom like xhausx. Once the phone boots up, call Sprint and have them walk you through provisioning everything. Once all is well, then move into whatever custom stuff he wants.

You took the words from my mouth!
Is he Flashing the RUU's or just running them through the computer? Normally, you sync your phone or through hBoot and then start the program, try flashing stock Froyo and then factory reset once flashed, it helps clear out traces of old roms etc. If you need anymore help feel free to ask, I would be more than happy!
I don't think it worked.
Calkulin's Format, flashed Odexed http://forum.xda-developers.com/showthread.php?t=1133379.
It showed 3G but I think it was misleading. Wiped and flashed to evodeck and it went back to showing 1x. My phone has 3G showing on evodeck next to his so he definitely has 3G coverage.
I guess it's just time to call Sprint for a re-provision? Does it have to be on a Sense ROM for them to reprovision?

you dont need Sprint to provision, just get your MSL code and do it your self plus I would do a search for people who may of had similar issues and see what they did. Now if that does not work then why dont you check what your network settings are.. See if its set to CDMA(Auto) I remember my Touch Pro I could of set it to 1x maybe something is getting stuck. I think its in ##3282 you check it and I also remember an app on the market called network that did it for you as well.
If that does not work then flash 3.70 radios and then a 3.70RUU and start from scratch.
He already tried ##data#. He can change his EVDO to automatic but it doesn't stay that way.
Alright I don't know how I fixed it but it's fixed.
Just cannot get 4G now. Wimax keys are present. It keeps scanning and cannot get connect. Previously could get 4G at these locations.
I am running EVO as donor/target phone, my is only 1x speed, no matter which rom I try
Synergery, Mik, Stock-Rooted, differ kernal, different PRL, check the data profile Automatic, Try restore but can not cat automatically update, still need to go qpst to update my profile. I have been working on this for two weeks. I went back to my orig phone, it show ev most of time, the speed is must faster than my evo. Searc all over from goole, still no luck, Anyone any idea to try

i know this post is somewhat old. but Making a back up wont take hardly and extra time! always always make one unless you have 100% reliable roms already backed up.

[Q] Data Connectivity Causes LGOG to Crash

I rooted and unlocked my ls970 and loaded Lifeless v14. Now the phone never shows data signal, and if I try to update the PRL, it will start a 3g connection, but the phone will immediately crash. It just goes back to the boot screen for about two seconds, and then starts working normally. wifi didn't work until I restored my efs. I don't know if that had anything to do with it. I tried an AOSP rom, and it didn't work either. I'm not sure what to do here.

Do a full restore with the stock BIN file, Its about 850MB, It will unroot your phone and restore your phone back to stock. Then check to see if the problem persist. Remember to update the PRL & Profile. Let me know if you need further assistance.

Thanks for the help. I flashed the stock image and then the 3g indicator was on, but data didn't work until I updated the PRL and Profile. After that it was working fine. I re-rooted, unlocked, and loaded lifeless rom. It is working like a champ.

[Q] Sprint Note 2 LTE Issue

Hello there, I have been in the search for a perfect 4.4 ROM to work, I seem to be at an impass..
The 2 that I have tried, and Quite enjoyed so far are the Omni ROM and the Cyanogenmod 11
Both roms have the same issue, I cannot connect to a 4g LTE Sprint tower. I know the LTE Towers are working, My mom has the same phone, Sprint Note 2 and I have Mac's Rom on it and is picking up a very strong 4g Signal, yet my phone which sits literly right next to it, Refuses to get any 4g.. I drove around, went to known working areas, Never once did I snatch a 4g signal.
I played with the settings, it is set to LTE mode, I even tried Flashing as a fresh Install..
I tried flashing a Stock rom, but for some reason after it installs, and on boot up the phone does not work. I get a blank screen and literly nothing. I have to pull the battery to get it to turn back on. At that point I have to either Re-flash or restore a backup through CWM.
Any help would be appreciated, I miss my LTE Thanks
Same issue here. Not sprint though...
In cm11 set your mobile network type to cdma+lte/evdo or global. See if that works.
Next you can try to flash a touch wiz rom and do a hands free activation, verify lte works on the touch wiz rom, then flash to CM11 and see if you can connect to lte.

I have tried setting it to both. Global shows no signel what so ever on anything, I currently have it on cdma=lte/evdo and I just get a good 3g signal..
I might try that one out, Which is a good touch wiz rom to try and do that with ? I dont think I even tried a touch wiz rom yet

Personally I would recommend doing this:
Backup everything to your PC (both internal and external)
Delete the contents of the "0" folder on your internal card. If you use ES File Explorer, you'll need to enable root access, and then while in the app hit the menu button. The left menu will slide open and you'll see "Local".... underneath that you'll find the "0" folder. The problem is the way CM and Touchwiz mount the file system - they don't do it the same way. So when you do a factory reset in CWM, it doesn't clear out one of those folders. (I found this thread helpful - especially posts 2 & 4) I had major data problems on CM10 for 2-3 months, then I found this out.
After you do that go back to stock. Make sure you download the keep root file as well.
To play it safe, once stock, I highly recommend entering ##72786# in your dialer. The phone will grab the latest prl and update your profile. Whether or not you want to update the software (incl modem) is up to you, but I'd rather not get into the knox world.
Verify working gps. (I prefer "GPS Status")
Then go back to CM11.
I will try that out thanks

Update us on your progress.
If it works, consider hitting the thanks button - at the very least the guy in that other thread - I know I thanked him - his info saved me from going crazy!!!
I had working data (3g/LTE) on any touchwiz, but not on CM. It turned out that I had some corrupted data that wasn't getting deleted upon a factory reset. After I cleared out that data, everything was fine.
Hope your phone is back to normal!
Finally was able to download everything and run the tip, Thanks a lot dude! That helped and that did it ! I got 4g Back and everything is all peachy!!! Thanks again!

Same issue with hotspot using super g2 rom.
I tried updating PRL but my data still goes on and OFF. Is there another hotspot mod I can use with this rom? Any help would be appreciated.
As a bump to this thread, and to keep the forums tidy, I, too, am having issues with SuperG2
I flashed it and it worked beautifully but I was unable to get any data service. I tried updating PRL/Profile but that would not work. Kept giving me a network error.
That being said, I finally got data to work (beyond me, not sure how this happened but I did NOT get PRL/Profile to update) and was using it merrily until I began to restore some files I had backed up via Titanium.
I rebooted to get the data from these files to run smoothly but after a reboot I lost all connection. It told me that my service was disabled.
I reflashed the ROM but am back to square one - unable to updated my PRL/Profile and cannot get any data, even tho the LTE logo is at the top and spinning. WiFi tethering works and I can access the internet in this way, but not in any other way.
I am being forced to go back to stock =(
Any help would be appreciated.

Connect to wifi then update the profile and prl (can be done at home if you have wifi, or mcdonalds, or starbuck, or anywhere that has open wifi)
Similar Issue
Running SuperG2, comming from Milestone1. I cannot seem to get the WiFi tether to work on SuperG2. It worked great on Milestone1. I tried the update PRL while Wifi tether is active but to no avail. I'm not sure if it's related but my signal kinda sucks too. Where I normally get 4g now I only get 3g with sparatic 4g and I also loose my signal altogether at times. I have to activate airplane mode and then deactivate it to get my signal back. I would go back to Milestone1 but SuperG2 is the frontline. Need to keep moving forward. Any help is appreciated. Thanks.
