Curious Case of My 4G

I got my EVO on launch day and promptly rooted it using Toast's Methods resulting in a fully nand unlocked rooted phone. Everything was just peachy until the incremental update came out. I was using a stock .6 ROM and when the update was launched I waited and used a Caulkin's 1.47 stock rooted ROM. I had never and did not at that point flash any radios/wimax updates.
Later that week, whitslack posted a radio/wimax update...I ran them both. The Wimax update took all of 20 seconds to write...it didn't seem like it did anything because of how quickly it wrote. I DID NOT live in a 4G area, so it was not possible for me to test.
I then started reading about how so many people's 4G was broke by different ways and became a little to addicted to the forums and it got to the point where my bar exam (life truly sucks) preparation started to suffer, so I ran the Sprint RUU and restored my phone to stock so it wouldn't serve as a distraction.
Once in stock I ran both OTAs and am now at stock, non-rooted 1.47. I still had no idea if my 4G worked or not.
When I open up my wimax_mtd everything is completely wrong...everything is broken, doesn't work...my DEV MAC says it is "%s". However, when I turned my 4G on my mac address under hardware information in settings matches the one on the back of my battery, even though it sits at scanning all day since there is no 4G service in my area.
So today I entered into 2 different 4G areas for the first time and my wimax connects fine and stays connected....
If everything is so screwed up on my wimax_mtd...why and how does my 4G still work? is wimax_mtd a root file that is still left on my phone?

[Q] 4G: How is it being damaged?

Hello everyone,
I live in Indy where we don't currently have 4G and don't anticipate on getting it anytime soon.
However, I keep seeing threads pop up where people have flashed a rom or done something that breaks the 4G capability.
Does anyone know how this is happening? I'd like to keep my 4G intact just in case I ever get the chance to use it. Have played with several roms already. Phone came with Froyo and did the downgrade root method.
Thanks!

there is no 4g support on aosp roms because the htc code for wimax is not open source. cyanogen only uses open source code in his roms and it is being reverse engineered at this moment. all the other sense roms should have working 4g w/ no problems.

Well, I'm definitely not "in the know" regarding the 4G, but I would assume ROMs do not have the correct drivers or settings for the 4G.
However, if you do not think you will be getting soon, why not simply "lose" 4G ? Should you get 4G in your area, wouldn't flashing to an official ROM "fix" the 4G again ? That would of course require you to reinstall all your stuff, and make all the settings the way you want them again, but that's only a few hours of work usually.

For example I saw a thread about someone who went from CM6 to Fresh and 4g won't obtain a MAC address. I did the same thing. CM6 to Fresh.
Someone responded and said he'd have to return the phone for replacing.

Hey fellow Sprint Evo user from Indy. Lets not worry about 4G in Indy, that won't come anytime soon considering Sprint can't get 3G implemented across Indy.

Here's how it happened to me....
I had my first EVO and I played with 4g before I rooted and rom'd it. After flashing a rom (Stock 2.2 rooted) it worked fine.
Then I had to replace my evo... so the replacement came, I opened it, and immediately rooted it. It wasn't even activated yet, and I did not play with 4g. After flashing Fresh 3.1.0.2 I noticed 4g wasnt working. I checked my MAC address and it was the same as under the battery, but for some reason my phone would not get past the "scanning" stage.
So... here's what I did:
I flashed RA Recovery and wiped everything and flashed to the latest OTA (HTC 3.26.651.6) which can be found here. After that I started playing around with my 4g, and got it to work. Then I flashed Fresh 3.2 and my 4g still works.
Someone had recommended I delete my tree.xml file which I never tried... a complete wipe did that anyways.
Anyways... sorry to make this long. Just chipping in what I have found. I hope it helps.

Yeah I'm not entirely worried about 4G. I just don't want to do anything unknowingly permanent. I tend to sell my phones on eBay when I'm ready to upgrade and a 3G only evo wouldn't be worth much.

the only permanent 4g damage you can do is to wipe the RSA keys. nobody seems to really know how this happens. it happened to my evo and i had never even rooted before.

Yeah my RSA certs got wiped; had an issue one night flashing a ROM and latest WiMax, things didn't wipe right and all hell broke loose, ended up flashing the WiMax radio twice and that seemed to do it. Someone else mentioned this here and that seemed to do it for me.

wait you got your rsa certs back? how????

Ahh sorry, no. I guess I see how that might have sounded like that. Meant someone else seemed to have the same issue, far as I know one cannot fix this themselves.
Sorry. New Evo coming from Sprint due to other issues, but that's how I ended up losing my WiMax.

yeah, i read his post at first like that too. when he said "that seemed to do it", i think he meant that is what wiped the rsa keys. but can we get clarification?
sprint basically needs to create a tool that restores rsa keys for the evo. i understand they have this for their 4g data cards already. i'm hoping they do this so i don't have to return my phone (which is otherwise perfect) for some effed up refurb.
EDIT: oops, didn't realize a pg 2 had appeared. so no rsa key fix here...move on...

are you within 30 days of purchase? if not, how did you get sprint to send you a new one? the CSR i spoke with told me they don't have the option to order new and when a replacement is ordered you will get refurb if they have them and new if they have no refurb. also, do you pay the sprint insurance? i think that factors into this as well. i pay the $7 insurance.

right, i agree that it falls under the manufacturers warranty and i am also dealing directly with sprint but they will not guarantee me a new phone as replacement. it's the hit or miss thing i described above. i called a corp store and they said the same thing. in fact, they said they had refubs in stock so i would walk out of the store with a refurb. i asked you about the $7 thing because i'm wondering if their systems treat the replacement differently depending on whether you pay it or not. i was literally told there is no way they could order me a new phone as replacement and as far as sprint reps go, this one sounded more "with it" than others. have you received the phone yet? is it really new?

Well, dude said it'd be new ... am waiting 2-4 business days as they didn't have any in stock at the store. He made it sound like if they had one in the back he'd hook it up, but they didn't. Am assuming it's going to be new. If not, I just hope I don't come up with some other issue if it is a refurb. Have had bad experiences with refurbished - uh - things in the past.
I didn't want to press my luck and ask if another Sprint store in the area might have any in stock, thus I could head elsewhere ... figured I'd just let it all play out. Time will tell though if it's new or not. As said, as long as I have a phone that works I wouldn't really mind a refurb. But I'd prefer a new one ...

right. i share the same opinion. prefer new over refurb. and i'm hard pressed to go the refurb route now with my only issue being non-functional 4g.
let us know what you end up with...

Yessir, will do.

Got the new phone, everything went swimmingly (do people really say that?) and it appears to be new, guy said it was new, not refurbished. Will have to check when I find the post that detailed the quick way of checking.
People were extremely helpful, 4G is back baybaaaay but also soon to be gone. But, I noticed I didn't have an SD card, not sure if he was supposed to have taken mine out and put it in, alas I just walked out without checking. Sat down with a beer and noticed and had to go back up there. All is well in the world, all is well.

[Q] Very inconsistent 4G

I have a rooted evo with S-off. I used http://forum.xda-developers.com/showthread.php?t=829045 to root my device and did not have any problems. I live in a 4G coverage area but my 4 G in very inconsistent but if I turn on 4 G antenna, update profile it will connect. My RSA keys are intact and my MAC address matches what I pulled up on ADB. I have been reading through post for 2.5 days as not to ask the same question twice. My wimax radio is 24722. Which I see is an older one but from what I gather updating this radio could ruin wimax completely. I hope I have provided enough info. Thanks to all the dev and ROM creaters!!! I was a ROM flashing fool with my HERO and I want my EVO to be the same experience!!!
Thanks in advance

If you flash a new radio yes it could ruin it. Big risk that way, if you update through you phone or ota it won't ruin it
sent from my EVO at the edge of hell

Today I'm in a really good 4g area and others with eve's have 4g but I get it for a few minutes if I update profile.

There is nothing wrong with the phone my friend i have been investigating this as well i need to do more tests but it seems once you flash a custom ROM your 4G is no longer as strong as it was from the factory. It wont matter if you flash a new radio, PRI or PRL, You can take a 100% virgin Evo and one that has been flashed over with the exact same RADIO PRI and PRL and you will notice a difference in the 4G Signal the stock phone will of course get a stronger signal. i have not tested this on a stock phone with just root access so im not 100% if this problem is Root related or Rom related but there is a difference.

Whenever I was running a sense based rom I never had a problem with my 4g. Not to say that what your saying might not be true I'm just saying that I personally had no problem with 4g.
Sent from my PC36100 using XDA App

I’m currently running a sense based Rom with all the same radios as the next guy I can literally put our phones side by side and his will pick up 4G where mine gets 3 bars of crappy 3G my friend down the hall same issue as me he’s running Baked snack I’m running Myns the other guy is stock we all got our phones at the same time so hardware is the same. I’m not *****ing just curious what’s causing the issue...

3G PROBLEMS (donate for help if i have too)

So i have rooted my phone a while back, and been flashing new roms back and fourth , but not sure why recently after a couple of weeks, i have seen my 3g signal drop without me doing anything, on the same places were i usually get perfect 3g signal,
i updated the radios to recent ones, update the profile , PRL profile etc so see if these was the problem that 3g drops all the time,
so i have flash myths , cya mods roms, MIUI , and evry other sense roms like HD SACS and fresh evo etc and i even try AOSP roms to see if the sense roms was the problem, but with AOSP Roms it even drops more,
example of what i mean:
i will be using the internet were it takes forevr to load cuz 3g dont kick in,
than out of no where 3g works perfectly for like 5 to 10 mins,
than after a while i try to use any application that uses internet like facebook, pandora, youtube etc, the 3g starts acting up and doesnt kick in , does this evry other 10 mins which its annoying the crap out of me.
PLEASE IF ANYONE CAN HELP ME I WILL EVEN DONATE $20 TO 30 BUCKS FOR YOUR TIME BY PAYPAL.
NOT SURE WHAT OTHER OPTIONS I HAVE, AND I REALLY DONT WANT TO REPLACE MY PHONE AND IM PRETTY SURE I CANT BRING IT TO SPRINT TO FIX IT CUZ ITS ROOTED, OR CAN I?
THANKS

Here is the best thing to try for starters.
Start completely fresh.
Download this zip
http://www.mediafire.com/file/ikylelx99c49133/Calkulin's_FORMAT_ALL.zip
flash that zip from recovery and it will format everything without a doubt.
Then flash a rom like this
http://forum.xda-developers.com/showthread.php?t=874251
stock rooted ruu - simple and no modifications.
If you are still having issues after this, then it is possible that you are having hardware issues.
It wouldn't hurt to try updating your radios as well
http://forum.xda-developers.com/showthread.php?t=715485 - the combo one at the top should get them all.

+1 those are the best suggestions than I think can be given to help with your situation. I had the same problem on my hwd 003 evo sent it in and got a hwd 004 speeds were better I think it was a hwd problem cause I couldn't find a fix.

i just try this like 2 hours ago, its going fine for now but still dropping the 3g couple of times, i just want to see how it goes by the end of the day...because this phone that i have its a replacement cuz my original evo i lost it, hopefully i didnt get a evo that has a hardware issue even though it was working fine for the first months, till now.
thanks again for ur help and ill keep u updated of how it goes and test it for a couple of days.

so i use it over the weekend, and after a day it starting acting up again, i was happy when it work almost for a full day and than it starting acting up where 3g wasnt kicking in, thanks for ur advise and i guess i have to replace this evo.

you might wanna try going to a Sprint store with service center, maybe they can figure it out there, as you've basically tried everything one can do at home to try and fix it, and are still having problems.

Here's one to accompany that. It may not even be your phone. Call *2 and ask if they are having network issues in your area. Mine was doing the same thing after a storm (we had tornaders...yes, tornaders...live with it). It was back up withing 48 hours, then again, I reported the issue.
I'm sure they have some pretty good monitoring systems in place; however, if the guys behind the NOC are anything like the guys here at my work...well I won't say anything, but you can piece together the picture.

nobody else i know have 3g issues, because i have ask my friends with evo's and my roommate to let me see there evo and check if the sprint network just acting up, but is not cuz there phone is running good. but it seems like i start getting normal 3g signal when i first flash a rom, than after a couple of hours or a day it start acting up, its annoying as hell cuz i could be in the middle of doing something during the day and when i need my phone to work with 3g, it start acting up,
thanks though for the suggestion, not sure if rooting the phone would effect the signal problem,

Just because you see it drop to 1x doesn't mean anything. That means that sense doesn't want you to know about it. so there is no icon for 1x since aosp is different and doesn't lie it tells you the truth. I thought things like this from time to time until I did this. Flashed stock. Speedtest... sat in the same spot flashed CM, speedtest. Both were about the same.. some tests were faster on CM then sense and some were faster on sense then CM. I get my email... and my market downloads never fail... So I can't really complain.

[Q] Which rollback PC36IMG to return to stock, then reroot?

latest questions were in june, so im going to ask to get a more recent suggestion.
im having signal problems no matter where i go, and i live in between 2 towers close by, one has 4g and im getting about ~1500kbps when i should be getting over 5k. 3G speeds are 10-60kbps down, market times out, and internet is useless.
Ive been doing alot of flashing of different roms, dunno if something messed up my phone, or an internal hardware problem, or what.. but i shouldnt be getting piss poor signal and speeds on ALL roms. Ive updated latest radio, and did all that extra crap. Same poor results.
so for a peace of mind, i'd like to flash an official sprint pc36img that includes radios, pri,prl, etc Then i'd like to root that, install amon ra, and flash synergy rls1 again. So that way im having a new fresh start and i can rule that out.
thanks.
EDIT: should i use unrevoked, or unrevoked forever?

Whether you are rooted or not, makes no difference on any problems with the radios. You do not need to unroot to fix it.
What you need to do, it to flash a stock ROM, about the time that you purchased the phone, then flash the radios from that time period as well, then you can flash up to the current radio files and whatever ROM/Kernel you want to use.
There is a full list of Radio Files, Recoveries, Stock ROMs, RUU files etc in the stickies of this forum.
Simple Search works well too.

Welcome to sprint. As stated above, there is nothing you can do about it, the network just sucks. I haven't gotten above 100kbps on 3g in over a year, and I live less than a block from a sprint tower.

thanks guys.. yea its a tower issue, i rolled back like suggested, flashed radios, etc etc.. same shyt signal. local tower is under maintenance.
