Root 4g stuck turning on

My battery is dying fast. At least 10% per hour under airplane mode. The only thing I see different is when I check Wireless Networks, under 4G is says "turning on..." It never connects and everything about 4g is grayed out.

I rooted over the weekend, but the only thing I have done is make a nandroid backup through clockwork and installed wireless tethering which I have only used once.

I have tried turning pulling the battery, Airplane mode on and off, disconnecting and reconnecting to the mobile network and rebooting the phone.

I think I will try a system restore next....
 
OK. System restore worked. 4g not trying to turn on anymore. What I found interesting is that clockwork mod restored all of my contacts, apps, and sms conversations. Neat.
 
OK, there is definitely something wrong. Just for the fun of it, I decided to try and turn 4g on. It gets stuck turning on, just as before.

So, what could have messed this up? The only thing I have done is root and do a backup. Is there any way of fixing this?

It's not really that important because I don't have 4g around me anyway, but could this be a symptom of a bigger problem?
 
try flashing a different kernel. I ran in to the same problem. If I use Myns warm with kings 11 my 4th will act up and do the same thing or 4th won't work at all. weird. let me know if that helps
 
I was thinking about flashing a new kernel and ROM, but since my phone was 3.7 before I rooted I was waiting on Myn's latest warm based on that build.

I guess the good thing is, I checked and I still have my RSA keys. I honestly don't see Sprint putting 4g into the Detroit area anytime soon, but we travel through Grand Rapids, Michigan a few times a year during the summer and I wanted to try it out.
 
Here is one thing you can try while troubleshooting 4g. Open a terminal emulator and type "su" then enter to get root. Then type "wimax_mtd" without quotes then hit enter. That will run through some tests and give you some information. There are a few other things you can look at, but start with that, and see what it does.
 
This is what I get with the wimax_mtd command:

Open WiMAX partition....OK
Get HTC WiMax Tag....Error
OK
Verify Wimax Tag (7)....NOT MATCH
Dump Wimax Tag (256)...OK
Read Wimax Partition......ERROR
OK
Check Firmware Version (4.6.2.3v27167_).........M
[1] + Stopped (signal) wimax mtd
[1] Segmentation fault wimaxmtd

The only thing I have done considering 4g is back-up my Wimax keys to my SD card.

I would ask you to verify you have your wimax keys before trying any of this, but if you already did, that's fine.

I can't find the thread where it told me how to verify that my keys were still there. I remember typing something in the terminal emulator and the last two lines were what I was supposed to have. Also, I backed them up using Good way to backup WiMax RSA keys. Works before Rooting, and on stock OEM Roms. - xda-developers and the file on my SD card is 4575kb, which is about what I am supposed to have.

I have been waiting for myn's RLS5 to be released before I try flashing my first ROM because it is based on 3.7 and all of the updated radios.

$ su
# grep RSA /dev/mtd/mtd0

-----BEGIN RSA PRIVATE KEY-----
-----END RSA PRIVATE KEY-----

I'm rooted (unrevoked 3.3.1), using stock rom...HBOOT 2.02 software 3.30.651.3 ...PRI 1.77 Heres what I get in TE

$ su
# grep RSA /dev/mtd/mtd0
grep: not found

SO... What does "grep not found" mean?

Did I loose my wimax keys? Of course I have a nandroid backup from right after rooting...

EDIT: "wimax_mtd" returns
a bunch of stuff, the first few lines show this:
Open wimax partition....ok
get htc wimax tag....ok
Verify wimax tag.....pass
read wimax patition...ok
check firmware version (4.6.2.2v26023_)...4.6.2.2v26023
check firmware file...match
and on and on...

Type "which grep" from the command line to see if it returns a path (the location of grep). If it doesn't work either, I'm going to guess you don't have busybox installed. Install it, then try again.

Basically, grep is just a command to search for strings in text files (or any kind of output/input depending on how you use it). When it says "not found" it means it can't find the grep command. That has no impact one whether or not you have your wimax keys. The fact that you can run wimax_mtd is a good thing.

Yes! Installing busy box from the market fixed it:

----BEGIN RSA PRIVTE KEY----
----END RSA PRIVTE KEY-----

Not that we'll have 4G here anytime soon! ROFL

A BIG thaks to you...you do so much for the EVO community, and it is greatly appreciated by this new EVO owner as well! :D

I suspected "grep not found" meant exactly what you said it did, but wasn't 100% sure.

Cool, that's exactly what you want to see :). Glad it worked for you; I'm always happy to help.

Funny thing about 4g, though, is even though we have it here, I never use it. I spend 85% of the time connected to wifi, and the rest, I'd rather have better battery life than a somewhat faster connection.

Yeah, I didn't buy the EVO for the 4G, I would have been very happy to have the same phone minus the 4G... but as long as it is capable of it, I didn't want to have messed it up! LOL...Thanks again, akazabam! I'm sure this isn't the last time you will answer a question about the EVO for me. :D
 
I've looked here and over at XDA, and for the life of me can't find a copy of the stock 2.6 #15 kernel. Does anybody know where I can find it?

Why doesn't XDA or this forum have a separate section for ROM's and kernel downloads so they are easy to find?
 
I am pretty sure there is a link to Roms and kernels in the rooting for dummies thread. I don't know how up to date it is.

Yeah, I saw that but don't know if the stock kernel in that thread is the one I have. It's 4 months old. I don't know if they used the same one from when my phone was updated to 3.70 in December.

I want to try flashing the stock kernel to my stock ROM to see if that fixes my 4g so I can make a new backup before I flash to RLS5.
 
What kernel are you using now? Those SBC netarchy kernels sure do a great job for me. I am gonna stick with stock #15 for awhile but if I don't find it to be that good, I will go back to that 4.1.9 v.7 or whatever it was. That thing was awesome.

Edit: you expressed interest in Myn's latest above. Just flash that and you will get your stock #15! ANd syou should already have the latest radios do you don't have to jack with that....although I would check to make sure.

I was hoping to fix what I have now in case I ever have to use my backup.
