Issues connecting to 4g

So idk what exactly is going on but last night I tried turning on my 4g and when it actually turned on it immediately turned back off...then I tried rebooting the phone and seeing if that helped but the same thing...then I tried doing a little research and I come to find that people have been losing their RSA keys and breaking their 4g...so I ran android ask and checked my wimax via adb and everything seemed as though it was there landing the right place (no errors) but I still have no 4g...now if I'm not mistaken I upgraded a few radios, including baseband and wimax, and I heard there have been connection issues with flashing those as well, but not "broken" 4g...so I'm just looking for a little direction I guess...I'm running Myn's warm rls4 rom and using netarchy 4.1.9.1 kernel (if the even matters) and when I go to check my 4g MAC address it says unavailable...can anyone point me in the right direction...I don't use 4g a lot cus I'm just outside of a 4g area but still, its the EVO "4G" and I would like to make sure it stays that way...if you know what I mean ;-)...any help is appreciated

To check your 4G MAC address, you need to first have your 4G radio on.

Read that to check your RSA keys and troubleshoot whether or not you have hosed your keys. If you lost your RSA keys, then there is no way ATM to get it back short of returning your phone for a replacement.

Did you update your profile after flashing the new radios?

that was the thread i found to help me check and see if my RSA keys were missing but they aren't...the problem i'm having is that my 4G is turning on but once it's on it immediately turns itself off...and i've tried this several times in a known 4G coverage area

yea i always update my PRL and my Profile after flashing new radios but still same thing...i only just now found out there was a problem tho cus i don't use it too often and when i went to use it, it wouldn't stay on and scan for a signal.
sorry btw for the late reply
EDIT: would going back to a different WiMax radio version help? i would try it without asking but i'm afraid to ACTUALLY lose my RSA keys so yea.

I'm having the same exact issue...any updates?

I'm in the same boat. I had to take my day 1 EVO (hardware 0002) to a Sprint store on Christmas Eve as I dropped it flat on its face and shattered the screen last week. Although I figured it wouldn't be an issue, rather than risk a small chance that they wouldn't repair under the TEP and $500, I went ahead and unrooted and returned to S-ON and loaded the new stock RUU.
So that moved me from HBOOT .97 to the new 2.10 - I then used the handy root guide for 2.10 and was able to re-root and S-Off without any problem, but my 4G would not connect (it comes on, shows scanning, but won't connect). It did connect a couple of times, but then dropped and have not been able to reconnect at all. Wife has an Epic so know a strong 4G signal is working at home.
I've tried the tree.xml trick and also checked to make sure I still have RSA keys which I do (even backed them up after checking again today). I've reflashed the latest radios, updated profile and PRL numerous times. Nothing working. 4G worked perfectly before I unrooted, and after I unrooted (with stock RUU). It was only after re-rooting with the 2.10 thread that this happened. I have not flashed any recovery other than the modified Amon-Ra since the Hboot update.
Wondering if anyone has unrooted, then re-rooted and been able to reconnect to 4G. I may give it a try - just didn't want to go through the trouble again if it doesn't work.

Just an update if anyone else is having trouble with 4G. I had previously used Myn's rom and stock, but since Myn's wasn't updated for the new radios yet I just flashed the sprint lovers Rom in zikronix's 2.10 thread, then tried out Azreal 3.0 (which I really like) - it was in both those ROMs that 4G would not work for me.
I just flashed back to deodexed stock rooted zip of 3.70.651.1 and 4G works again!

[Q] 3g signal weak after constant flashing??

Hey guys my 3g is not as fast anymore after constant flashing of roms and radios and now I never get over 500kbps..any suggestions?

I've been having the same problem! I seen somewhere about reconnecting your phone with Sprint towers, but can't find the post about it again anywhere.

Did yall try updating your profile?

Ive updated my radios, prl, profile..and I always do complete wipes and wipe multiple times before I install a rom..also I tried that data govenor removal mod and still nothing..i really dont want to unroot and bring to sprint to replace

Sorry but thats all i got. Ive noticed sometimes i get bad reception but i havnt up dated my radios since fresh 3.4 came out. Ive been running cm for a long time so that might be it but its not enough to make me flash back to sense to fix it. I hope you get everything figured out.

Hey no problem man I appreciated the help..I guess my next move will be to flash fresh Rom..the speed seems to come and go on myns rls 5 but on any other Rom speed is completely horrible but let's see..ill get back with results.

I've been having the same issues. I've noticed when running the speedtest app sometimes it detects the closest server being over in Europe (I'm from Wisconsin). It appears to be tower related. When I'm on the tower closest to my house it detects the closest location in Missouri? Awkward. I'm on CM 6.1.2 running snap 7.6 with turbo enabled. Most times I see speeds of .3 mbit. Turn on wifi and I instantly max out my connection at 8 mbit. If only 3g were that fast, lol.

[Q] My wimax is not working and i still have the keys, why?

I know it sounds like a **** of a question but do you live in a 4 g area

The most common cause of this is something corrupt in your data profile. this is fixed by updating running a data profile update.

as the above poster says try updating your profile. if that doesnt work try wiping all data/factory restore and reflashing the rom and trying again. Also make sure you have the radios for your rom. Ie if on a 3.7 rom you should have the latest radios if on an earlier rom you may want to try the previous radios.
what method did you use to verify you still have RSA keys?

i recently i a prob w/ 4g after switching roms. i updated the profile like 4 times, went to a non 4g area, turned on 4g, let it settle, turned it off. later that day i went back to the 4g area, turned it on, and BAM! worked great. My exact problem w/ 4g was it went from scanning, to connecting w/ sprint, the authorizing (for s spilt second), and back to scanning and so forth, over and over. hope this helps....

[Q]Problem with PRL updating

I'm glad I'm not the only one, I flashed an older RUU earlier and I've been trying all night to get my PRL updated again. It looks like I'm stuck with 60662 for now.
If you turn off your 3G for a second it should come back on but I'm thinking the PRL issue is something with Sprint's network. I've tried just about every ROM/RUU/Radio combo I can think of and nothing. Updating my profile does the same but I haven't tried re-activating it for fear that it will get stuck in limbo.
edit: yup, it's not going to update tonight. I'm going to quit flashing radios now before I brick my phone.

good, ok seems like its a sprint issue then, im located in leesburg, FL just head up guys!!!
also i dunno if anyone else has had this issue but 4g will work but if i run speed tests a couple of times it will randomly stop working without disconnecting...

I'm not too far from you then, I'm over here on the space coast. Sprint has been turning on a lot of 4G here lately so their network hasnt been acting right for at least a week now.

ah thats pretty cool, its good to see that 4g is getting activated or "tested" in alot of FL. even my area is getting it alrdy... and im in old people land... haha

PRL updated.... I finally got my phone back to normal after thinking I hosed it and my 4G speeds doubled what they where day before yesterday.
Signal is still just as weak though.

hmm mine seems to still not update... u do anything differently?
update: nvm there it goes

Won't Connect to 4G

So everything was fine on my Evo (running one of decks roms with a ICS theme) until the screen went out friday night. Saturday I took it in and it was repaired in about 2 hours (very impressed). In between I activated an old back up phone to get me by. When I picked up my Evo the tech had reactivated it and it was ready to go. But when I got to work I had no data. No internet service at all. Calls and Texts were fine, but nothing else. I made sure mobile data was checked, (couldn't update PRL cause of the AOSP rom), but I did a battery pull, rebooted, then I decided to nandroid back to a previous sense rom. Once I booted up still nothing. after about 2 hours all of a sudden I was getting emails, and voxer messages....I had data back!!! But when I tried 4G nothing happened (stays on obtaining IP). Hoping a newer stock based rom would help I flashed the new swag ON rom. Loving the rom...everything is great, but still no 4g. My last resort is to unroot and go back to sprint. I downloaded the wimaxx checker and it says I have my RSA keys so I know those are there. I'm sorry if this is a bit long winded, but I thought being as detailed as possible would help. Any suggestions would be great. The members here have helped me through lots of trouble shooting in the past.
Should also be noted that I attempted PRL update again with no luck, and I live in San Antonio which is a solid 4g area for me.

Good thinking with Wimax Checker - That's usually the first line of defense.
It sounds like because you cannot update PRL or Data Profile that there may have been an issue in the reactivation by the tech at the Sprint store. With that said, I know I'm in the Philadelphia region with good 4G but occasionally there will be a day or so of PRL/Profile update "outages" where I cannot update. I usually will verify with a family member's phone (also on Sprint). Perhaps try having someone you know in the area with Sprint and an android phone try a profile and/or PRL update to make sure it's not just the system being unresponsive.

Ok I will try that tonight and reply back. I had my g/f's evo running decks rom try her 4g and it worked perfectly so I know its my phone. I'll see if she can update. Either way is there some sort of combo pack I can flash for profile and prl??? I'm not too sure how that would work.

Here is the latest Radios-Wimax-PRI-NV Combo pack Click HERE

Ok I flashed an older Wimaxx since the one I had was up to date(did a check in TE). Once flashed and booted up still no 4g. Is it possible that this could be a hardware issue since everything else works? Like the actual antenna is busted? Just hard for me to think that since it was working fine before my screen went out. I always have 4g service at home and work. And my g/f's is working fine she has the evo and she has sprint.
