4G Won't Connect

[jjbehren]

I cannot get my EVO to connect to 4G. It turns on, scans, and then says "disconnected." I know service is available - my wife's stock EVO connects.

After researching this issue for quite a while now, I think I'm now more confused than informed. Any help would obviously be "thanked."

My EVO's history:

Got it on release day. Hardware version 0002. Still on HBoot 0.76, for what that's worth. Stock ROM for quite a while, but did not do any OTA updates on it because I knew I wanted to root and flash another ROM later. Once Froyo came out I flashed to OMJ's 2.2 ROM (don't remember which version - probably his first or second 2.2 version). I can't remember if I attempted to update any radios or anything at that time. And I never bothered to check if 4G was working since Minneapolis didn't have 4G service yet. Thought I remembered reading somewhere that OMJ's first couple of 2.2 versions didn't support 4G. Don't know if that makes sense though.

Once Minneapolis got 4G I tried it on my EVO. With the ROM I was on the antenna wouldn't even turn on. I flashed OMJ's latest ROM at the time (v4.2). Now 4G will turn on, scan, not find anything, and display "disconnected." I updated my wimax radio to 4.6.2.3v27167_, as well as the other update on Calk's combo update (radio - 2.15.00.11.19, etc.).

Here's what I know: Through a terminal emulator I've learned that my Wimax MAC address is correct. I ran wimax_mtd and everything came back OK/Pass/Match. I ran "grep RSA /dev/mtd/mtd0" and got "-----BEGIN RSA PRIVATE KEY-----/-----END RSA PRIVATE KEY-----," so I'm assuming my RSA keys are cool.

However, the Wimax log gives me this:

#tail -f /data/wimax/log/*.log

23:51 7.984 >| SQND/Device info >| notifyReady: ready

What should I try? Should I start over? Flash back to stock (Calk's Format All > Wipe > stock ROM > OMJ v. 4.4)? What about the radio? back to stock too?

I like to consider myself pretty good at this stuff, but a programer I am not. Any help would be greatly appreciated. I will obviously thank you.

Also wanted to mention that I did post in the OMJ thread and was told I need to find a thread on how to repair my wimax. Doing a search for "repair wimax" or "wimax encryption" didn't return anything.

Thanks again.

all i could find about wimax possible fixes

[JeffKay]

Check your 4G Mac address.. is it the one it's supposed to be? Look under your battery. For me... I flashed a bad file for the WiMax radio and permanetly killed my WiMax. RSA keys were gone. I had to do a dance at Sprint to get them to replace it, which I finally succeeded at.

Thanks. I had found that first one since I posted the above. I'll look through those tonight.

As stated in my first post, MAC address matches what's under the battery. And it looks like my RSA keys are fine. Thanks though.

lets know if you get it fixed

[kevmo1965]

I've never been able to connect to 4G. I'm not in a 4G area, but when I've traveled to a 4G area it's never connected. Keep us posted what you find out.

[jjbehren]

God, I feel so much pressure now.



I'll be sure to let you know. Maybe I'll throw together a what I (think I) learned after this is all said and done.

Have you ever done a Nand Restore? When you did your Nandroid backup, what Recovery were yopu running?
I am supicious of a corrupt RSA key.

[jjbehren]

Never did a restore, no. And I fear for my RSA keys, too, if I have to use my backup from when I first flashed to OMJ's 2.2 ROM. I followed the steps in the older videos posted at the bottom of http://forum.ppcgeeks.com/1793724-post1.html. From reviewing that video, it looks like I would have used the Run > c:\evo-recovery backup method for my first backup. I hate to admit it, but I'm having a hard time finding my backup from then. It's not on my SD card. I might have put it on my laptop, which my wife is using right now.

Again, went straight from release-day stock with no OTAs to one of the first versions of OMJ's 2.2 ROMs to OMJ's 2.2 v4.2 w/ Caulk's combo radio/wimax/pri update. So only 2 flashes (with clean, double wipes) and the combo update ever done on this phone.
