So what do I do anyone know what to do
[EVO 4G Android Development] surmanm:
i lost/ broke my wimax / rsa info after re-flashing radio when i do a nandroid of my old backup with working 4g this doesn't seem to fix the problem .

i turn on 4g, phone find 4g authenticates and tries to connect then drops it.then scans again

i tried accessing via fastboot PC i get a error device not found mssg... im stumped dont know where to go from here to fix the problem any help is appreciated

when i go to about phone > hardware information i see

hardware version 0002

4g mac address unavailable
[EVO 4G Android Development] m4f1050:
If you turn on 4G you will then get the MAC address.

If everything else fails you can always put back to stock and return phone to Sprint they should be able to replace phone.
[EVO 4G Android Development] surmanm:
when i turn on 4g i see: scanning> connecting to sprint(4g is available notification)> authenticating then back to scanning. i must have messed up the radio

how do i unroot and put back to stock if someone can point me in the right direction ? sorry for the noob questions i seached but couldnt find the thread
[EVO 4G Android Development] m4f1050:
I saw this behaviour when I restored wimax.img on 2 phones and had them both on at the same time. Also when the account on one of the EVOs was cancelled.
[EVO 4G Android Development] EJayMz:
Broken WiMax

Not sure what I did. Flashed a few ROMs and 4G not working. Flashed CM6.1, Myn 2.2 rls 4, MIUI, and a few others.

This method isn't working for me. Any new instructions out there to fix WIMAX? I have the 'dreaded MAC listed above'.
[EVO 4G Android Development] mhmobile:
I read somewhere in this thread that you can copy someone else's RSS files but only one person would be able to connect to 4G at a time.

Has anyone confirmed this?

Reason for the question is I do not have any of the required files in my mtd folder and a friend with a rooted EVO could not copy his files so they could not be copied to my EVO. Just trying to see if I installed this files if it would make any difference in my 4G reception. I still connect to 4G but wondered if I would get better coverage. One other thing, all of the files in the mtd folder were zero bytes. What's with that?
[EVO 4G Android Development] nickdiehl:
hi im looking for help with updateding the wimax radio and pri, i have full root and have the rite MAC address, i can flash the radio and NV but not the wimax and PRI, iv tryed flashing them with both rom manager and adb and they wont flas im running fresh 3.4 and the wimax radio ver rite now is 25043 and the PRI is 1.40_003 and help with this?

i found problem had s-on, turnd s-off and problem fixed
[EVO 4G Android Development] scottspa74:
I'll admit, I really haven't read thru this thread, but wanna throw a quick question out here.

I never used the old unrevoked that broke peoples 4g. I rooted 2wks after launch using toasts files. My 4th scans, then says 'connecting', then 'obtaining ip address', then 'connected to Sprint'.

The issue I have is that it only connects for about 15sec then goes back to 3g, then starts the scanning/connecting process again. Would this be evidence of broken 4th, or just bad reception?

Any response much appreciated. Anyone else experience this? Thanks.
[EVO 4G Android Development] Morphean:
Do an PRL/Profile update. Turn off phone and pull battery. Boot phone back up

Hopefully that worked.. It fixed my 2 EVO.
[EVO 4G Android Development] bboy_201:
hmm

I got

any help?
[EVO 4G Android Development] chaoticallysweet:
I used code:

help

i treid and recieved this

UPDATE

I finally changed my 4G MAC address

but still when i turn 4g on it scans thans says connecting than loops over and over

I do get the notification stating that i do have 4G in my area,,,,,.....:mad:
[EVO 4G Android Development] deseo:
how u get to change the mac? any steps? can u share please?
[EVO 4G Android Development] bboy_201:
follow the op

i some how was able to edit just the the op stated

when i first tried i received errors. but i looked through many post and tried what they said. Nothing fixed it but when i came back here n tried it it worked. im not sure what i did to fix the errors tho
[EVO 4G Android Development] jacoballen22:
Okay, I have a question. My 4g doesn't have numbers, it just says unavailable. It also turns on, then goes right back to scanning.

[EVO 4G Android Development] leenypost:
The mac address is located under the battery. You have to have numbers listed next to the word WiMax. Also, I have the correct address and my 4g works. Sometimes I have encountered the problem you are mentioning. Wipe Cahe and Dalvik twice. Reboot and problem solved for me. Hopefully that works for you too.
[EVO 4G Android Development] leenypost:
I have a question for anyone that might know the answer. Lets say you have a broken 4g issue due to flashing a bad address... Can you use an official Sprint RUU after flashing zip for S-ON and everything would go back to complete stock and be correct again? I thought the RUU wiped literally EVERY BIT OF DATA in phone and rebuilt it from scratch... Is that incorrect?
[EVO 4G Android Development] jacoballen22:
Seems reasonable so now if I could get to Chicago to test it.

Swyped from my HTC EVO 4G via xda app
[EVO 4G Android Development] m4f1050:
You need to check the number after it's been turned on. Same applies for Wifi & BT mac addresses...
[EVO 4G Android Development] hawt:
Followed all of the directions to change my MAC address and now I am getting a step further than before.

Previously it would just say Scanning and then Connecting to Sprint and then just kick back out to Scanning...

Now it goes from Scanning then Connecting to Sprint, then it says Authenticating before it kicks back out to Scanning...

Sprint's 4G is a joke. $10 extra a month for this ****? Really?
[EVO 4G Android Development] bigbiff:
Did you check for RSA certs? adb shell grep RSA /dev/mtd/mtd0: look for BEGIN CERTIFICATE lines. If there are none, you need to get a new phone.
[EVO 4G Android Development] hawt:
Yeah I checked for the certs. Looks like I need to get a new phone.
[EVO 4G Android Development] George M:
I do have the RSA keys on my phone. However the MAC address is not correct.

It is not the 00:16 etc address, but not what is under my battery.

The question is do the keys match the incorrect MAC or are the keys the original and correct keys? How can I tell.

If the keys are good, with the directions to change the MAC be enough to get back to 4G?

Re-flashed Wimax from original post on page 1 and all is now fully repaired.

I didn't have 4G after going back to Fresh 3.4 from Fresh Evo 3.5 (to me it seems to be a work in progress).

My thanks to the OP - Geniusdog254 and other contributors to this thread.
[EVO 4G Android Development] mqutub15:
Why does 4g break?

Hello I have an EVO and I recently broke the 4g, I was wondering what broke the 4g. I rooted it using the 2.10.00001 instructions that recently came out. It installed the sprint lovers ROM on there and the 4g worked. Then I installed Fresh Evo and did some Wimax or radio updates that were with it. I don't know if that was what ruined it, but I am getting a new evo and want to know what not to do again so it doesnt get ruined again.

Please advise. Thanks.
[EVO 4G Android Development] aimbdd:
This. Updating the radios killed it. Unfortantly with no way to fix it :/
[EVO 4G Android Development] m4f1050:
Did you do a NAND backup with recover_RA_v1.8.0 before experimenting with it?

Chefs should advise to do nand backups (which I do belive they already do) and the first thing people should do that are experimenting with their phones should be a nand backup. #1 rule for me, #1 step for me.
[EVO 4G Android Development] bigbiff:
Everyone, please update radios through hboot. Since we can now get S-Off, you can create a PC36IMG.zip and dump your firmware images in here. Apparently I hear that hboot stores your certs temporarily before upgrading the wimax partition firmware, then restores them properly.

This is how I update radios after I blew up my first phone.
[EVO 4G Android Development] igotroot:
That's interesting.....I believe I flashed Caulkins all in one radios update using Amon Ra recovery, and it worked flawlessly...

Have a link to read up on that theory?
[EVO 4G Android Development] m4f1050:
I flash from 2.05 to 2.15 all the time and I haven't broken my 4G doing so... Just FYI...
[EVO 4G Android Development] craig198:
so what fastboot oem commands do we use for the evo? i dont even get a mac address following the guide
[EVO 4G Android Development] majorkillin:
Ok, I have completed all the setps in the this guide and 4G will still not connect. I originally got the problem after flashing the latest radio combo pack from here.

http://xdaforums.com/showthread.php?t=715485

I am running MikFroyo version 4.2 and I flashed the radios using ClockworkMod. After flashing the radio pack 4G would not connect. Found out the MAC address was wrong.

I re-rooted using Toast's Method Part 2 and corrected my Mac address. Loaded a Basee RUU inorder to get all the radios working again. (for awhile 4G and Wifi would fail to load).

Current back to the following versions.

Rom: MikFroyo 4.2

Baseband: 2.15.00.11.19

PRI: 1.90_003

PRL: 60674

Wimax: 27167

Right now 4G will say it is Connecting to Sprint and sometimes it will say it is Authenticating. Then it will disconnect and go back to scanning. This will repeat for awhile until it gives up. I am in Atlanta so there is good 4G where I am at.

Here are my results from the ADB Shell Commands. Looks like my RSA Key got wacked.

guys will a donor wimax.img get me anywhere? or is there alot of steps im missing.
[EVO 4G Android Development] wase4711:
nope, because then the "donor" wont be able to connect to 4g/wimax...
[EVO 4G Android Development] Ph33zy:
I'm a little concern. I'm in a weak 4G area and can connect to 4G sometimes. When I run wimax_mtd, I get the following:

Open WiMAX partition...OK

Verify WiMAX Tag.... NOT MATCH!

DUMP WiMAX tag (256)...OK

Read WiMAX partition...ERROR

I still do have my private RSA keys when I run the GREP command.

I'm wondering if the errors above is causing my connection to be flaky?
[EVO 4G Android Development] tkwill:
If you have SwitchPro (or another third party 4G toggle) try making a toggle for it. I couldn't connect through systems menu but I was able to through Switchpro. I rarely use 4G so I hadn't noticed it until after I started reading about all of these issues. I started worrying and found this to work for me.
[EVO 4G Android Development] majorkillin:
Sounds like you might need to reload the Wimax radio driver. Looks like it might be corrupted. Does your 4G work?
[EVO 4G Android Development] majorkillin:
I tried using the 4G toggle from Beautiful Widgets and it still fails to connect. From what I've read my problem is my RSA keys are gone. And there appears to be no way to restore those at this time.
[EVO 4G Android Development] Ph33zy:
4G is working....but sometimes it takes a while to connect. I am in a very weak area though and have only 1 bar. How do I reload the driver?
[EVO 4G Android Development] majorkillin:
Might just be your coverage. But go to here for the latest Radios.

http://xdaforums.com/showthread.php?t=715485

Make sure you do a Nandroid backup just in case! This is what broke my 4G. Should have done a proper backup. Guess I learned the hard way.

Also there are ways to tweak the 4G radio settings. Check out this thread.

http://xdaforums.com/showthread.php?t=889025

You'll need you MSL, but there is an app that can pull that for you without needing to call Sprint.

*Can Someone Help Me?*

Peace All,

For the last couple of days my 4G had been acting really flaky (for the record---I live in Philly w/ the full 4G experience). Then last night my 4G wouldnt work at all---so i thought i broke my 4G. So i used the formula here:

1. Download terminal emulator from the market. Then open it.

2.Type "su" (without quotes) press enter.

3.# will now show up.

4.Type: "grep RSA /dev/mtd/mtd0" (again no quotes). Press enter.

Give it a few seconds and a bunch of stuff will appear. Now to assure you still have your RSA keys look for this at the end:

-------BEGIN RSA PRIVATE KEYS------

-------END RSA PRIVATE KEYS------

If the begin/end private keys shows up then you are in good shape. If they do not, then unfortunately your RSA keys are lost.

When i did this it said my RSA keys were in tact---but when i go into Settings<Hardware it says that 4G MAC address is unavailable. Should I follow the OP's directions in 1st post or should i re-download the the latest Wimax radio?

any help would be greatly appreciated

-ZDK-
[EVO 4G Android Development] AssassinsLament:
The MAC Address will say unavailable if you didn't turn on 4G. You should be fine as long as your 4G MAC address is intact. I wouldn't do anything too extreme because you could mess up your 4G even more. Make sure you make a backup of your 4G before you try anything else. Do that first, then you can try to update your profile in your settings.
[EVO 4G Android Development] ZEDEK:
Thanks Assassins,

Still cant get my 4G to work---even after installing newest Wimax radio---i wonder if its my phone or a Sprint issue---I've updated PRL & Profile and also ran RSA keys test again.

-ZDK-
[EVO 4G Android Development] cheebahawk:
I'm in the philly area as well, and currently my 4G is not connecting AT ALL.

So it may be an area issue since we're both in the same city.. I just tried your method and both my RSA key entries are there.

I just checked the WIMAX mac address (in the hardware info vs the back of the phone) and they match.

How far are you getting in the connection process? I get as far as it saying "connecting to Sprint" then to "Scanning" then finally "disconnected".

I'm about to call Sprint to ask whether 4G service is flaky in Philly at the moment. (UPDATE: Sprint rep told me that there are no outages in my area).

DOES ANYONE HAVE ANY IDAES ON WHY IT WILL NOT CONNECT TO 4G IF:

1) sprint network is okay in my area

2) Both the WIMAX address in the settings and back of the phones match

3) I have both the

-------BEGIN RSA PRIVATE KEYS------

-------END RSA PRIVATE KEYS------

lists at the end of the terminal emulator sequence?

UPDATE NUMBER 2:

After speaking w/ Sprint Rep for frustrating 20-30 minutes My 4G is working again:

These are the steps I followed:

1) ##3282# Need MSL number (download MSL Reader from market so you dont have to call Sprint)

2) Enter the MSL number and go into edit

3) First option is profile something click on it. Then hit menu and you will see right hand side RESET option click on it. Phone will reset

4) This will take a long time resetting the phone (My Evo actually got stuck on the white HTC screen for 15 minutes, so I just pulled the battery back out at this point. Upon restarting the phone after battery pull, the phone loaded correctly, albeit took a long time again at the FRESH screen).

5) Once the phone is fully loaded, go into settings and update profile. This process will update profile & reactivate your phone, update your PRL and search for firmware update (there is none). Afterwards you can try clicking on 4G to see if it works.

6) 4G failed several times and then it reconnected.

Sprint rep wasnt that helpful and wanted me to hard reset my phone after step 5, I just hung up on him and tried it again and it worked.

Oh and for those that cant put in the initial code into the dialer in step 1, you are likely missing the SPRINT ZONE apk. You will need to download and install this on your Evo to input the code or it will either force close dialer or go blank.

I hope this will work for others as well.
[EVO 4G Android Development] cheebahawk:
Well spoke too soon. I disconnected from the 4G network to see if I can reconnect, and what do you know I cant connect to it anymore! :mad:

I dont know what the hell is going on now...
[EVO 4G Android Development] AssassinsLament:
I would wait a day or two, since you two are in the same area, it's probably issues around your area and not your phones. As long as the keys are there, don't worry too much.
[EVO 4G Android Development] cheebahawk:
I would hope this is the case, but Sprint reps (two of them) checked & told me that the 4G connection/network around PHilly is fine and there are no reported outages.

I wont be able to know for sure until tomorrow morning, when a) I can test my better half's Evo at our house to see if it connects and b) call couple of my buddies around town to see if their Evo can establish a 4G connection.

I just got done unrooting my Evo to take back to the store tomorrow just in case, even unrooted I am having no luck connecting to the 4g network.
[EVO 4G Android Development] ZEDEK:
Peace cheebahawk,

I think it was a Sprint issue---my 4G is up and working now

update PROFILE & PRL

[EVO 4G Android Development] cheebahawk:

[EVO 4G Android Development] wtwildnateis:
I am just simply lost to a point to I don't even know what the hell is going on haha. Basically when I power up my phone my 4g will be fully connected. But then it will shut off and 3g will turn on so on so forth. Of course when i go to turn it back on 4g takes a couple of seconds, then scans for a split second then instantly turns off. I have checked absolutely everything. Mac address is correct and my Keys are there. I'm not sure what is causing this problem, maybe an app I have?. I dunno I noticed this awhile ago, was running Myn's RLS4 now on RLS5 but it began on RLS4 and it happened pretty much out of no where. 4g would work all the time for the longest till about a week ago. I wanna say it happened about the same time sprint began rolling out the new ota, though I did not update to it. Most confusing thing ever. Any help would be much appreciated. Im just so confused as to why it connects perfectly and runs right after start up for atleast a minute possibly two but wont turn back on.
[EVO 4G Android Development] jirafabo:
Well what about a donor wimax.img if I have my RSA keys backed up? Is there any way to get the correct RSA keys into the wimax.img or is the entire wimax.img unique to every phone.

Also, if I just wanted to correct my Mac address and return to stock, would the correct mac address stay after i flashed back to stock using a p36.img (or whatever its called)?

thanks. I need to return my phone and the last tech i spoke to said the mac address was wrong and therefor it had been modded, even though i returned everything to stock.
[EVO 4G Android Development] jirafabo:
I wish people would stop talking about RSA keys. RSA keys themselves are USELESS. The term should be banished from the forums as it just spreads a false sense of security. The wimax.img is what has to be backed up, backing up RSA keys is a waste of time.

[EVO 4G Android Development] mikel719:
OK so I just rooted my phone the other day. used autoroot 2.2 it did say that it created a nandroid of the wimax.img. My sd card got messed up so am I up sh!t creek? It erased everything. I did however check my wimax mac address with the ##???# i think it was 786, dont remember though. anyways my wimax address from there showed to be the same as the one under the battery. I did make another nandroid back up of it in amonra recovery 2.2.1 and copied the wimax image to my computer. I have no way of testing as I live like 135 miles from a city with 4g. So my question is, since the mac addresses matched up should I be fine when and if I ever get 4g where Im at? I wont be heading to a place to test anytime soon. The only rom I have flashed if that matters in calkculins evio 2 version 1.7.7. Any advice would be great, just dont want to end up with this problem and would hate to have to wait for a replacement from sprint. Thanks for any help or info in advance.
[EVO 4G Android Development] wtwildnateis:
Yea man it's really weird. Like I've been rooted for probably 4 months or so now and have been running the same myn's rom forever. 4g worked all the time till recently started before I even flashed the new RLS5 of the rom. Just randomly stopped working awhile ago. I'm assuming it might be a bug in the 4g radio/ or network. It's kinda of annoying to be completely honest, and im sure everyone feels this way to. I mean I dont really care cause 3g works just fine but since the phone is a damn 4g device is should run on 4g when i want it to. haha. One of these days im gonna call sprint and see what is going on, maybe they turned my 4g off by mistake or something. Though im also starting to wonder if it has to do with the phone in general like the whole 003 and 004 and so on. I have 003 and have had it since the day the evo came out. But I dunno, im just as lost as everyone haha......
[EVO 4G Android Development] nzaw4:
I wonder if we downgrade our radios or pri if that would help.. I'm just scared in losing my MAC and keys
[EVO 4G Android Development] TheMatrixx:
If your keys are gone, you'll see "Authenticating..." then it'll go back to disconnected.

I had problems before, where it'd fully connect, but then immediately disconnect - turned out to be a SwitchPro widget I had installed went nuts and was forcing 4G off every second.
[EVO 4G Android Development] nzaw4:
Yea my keys are there, was connecting last week, now it goes from scanning to disconnect. And no switch pro widget
[EVO 4G Android Development] TheMatrixx:
Have you wiped everything and reflashed a Sense ROM?
[EVO 4G Android Development] wtwildnateis:
YOU ARE A SAVER!!!! It was switchpro messing with my 4g, i just uninstalled it and turned on 4g and it connected instantly. Man I am soooo stoked right now haha
