[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] Radio 11.19 Leaked Evo for Inc.

i dled the 11.19 evo radio and my text messaging started getting 10 min delays, then 20 min delays and sometimes none. i flashed back to the official 7.28 radio to see if that solved the problem, and no it didnt. any ideas from anyone?

Did you *228 (program) your phone after you flashed your radios? Have you contacted Verizon to tell them that your texts are taking a long time and see if maybe it's something on their end? I'm on Cricket and they use *228 to program so I guess I really don't know what Verizon uses but you get my point.

With Verizon it uses *228 option 2 or *22899. I have done that quite a few times with no luck. Everytime I ask Verizon all they want to do is tell me things I have tried already and get nowhere.

It's probably just a coincidence and Verizon is just having problems with their service right now in your area or something then. They are probably just too proud to admit it. Ha ha

HaHa. That's a good one. I hope your right though. It's kinda annoying. God forbid there is an emergency and I don't get the text cuz of the delay.

From my experience with cell phone companies, they all have trouble like this from time to time. Mine does it every once in a while and my buddy on AT&T, his does it ALL THE TIME even with the "all mighty iPhone", my brother is on US Cellular and same deal. My girlfriend is on Sprint and she don't get texts sometimes till the next day! It will probably work itself out. Good luck man.

my questions & concerns about the epic4g!

okay so i made the leap and traded my evo for a newer epic4g. i love the clarity of the screen and the overall speed blows the evo away. downside is some of the bright colors look washed out and the screen is smaller.
my question is when is the epic getting official froyo so we can have more development? such as roms & kernels?
will the epic even get gingerbread at all?
my concerns and observations are:
the proximity sensor is very sensitive and i find it often does not work as even when i have auto rotation disabled i find certain apps like my phone will go into landscape mode and get stuck there.
cannot update my prl or profile without the use of qpst? i mean i assume this is a software flaw? ive seen lots of people have this issue and it must be reported and fixed by samsung IMO.
really bad radio signal life compared to the evo. i have no idea what the difference would be?
ive noticed compared to the evo i have less free ram. i usually had about 200-250mb free and now i have only 140-170. whats the difference here? would a custom kernel possibly fix this?
also id love to know why there is no working version of apps2sd as i feel it would benefit the free memory the phone has.
as i said im not here bashing but giving my observations and to tell you the truth if these issues cannot be fixed ill for sure be going back to the evo. i sorta see why samsung have a bad rep.
can anybody give me any fixes for some of the issues i posted?

Auto-rotation has nothing to do with the proximity sensor. You probably need to run /system/bin/sensorcalibutil_yamaha as root and follow the instructions.

Be careful op. People here like to flash their e-peens when you have a negative observation towards the phone.
Luckily some are more open minded and will help
Have you rooted the epic?
I'm on stock froyo dk28 and I get almost 2 days out of my phone, but that's with only using 4g and wifi because 3g is of no point to me unless I go somewhere out the city
There's a developer "noobnl" who's working on a gb port, but its not gonna be completed until official froyo sauce straight from samsung comesout
You should've held the evo for a bit until the epic got official 2.2 because then you would've definitely not have had any type of buyers/traders remorse

There mightve been something wrong with the modem flash
I couldn't upate m prl when I first updated to dk28 but after I flashed back to 2.1 then 2.2 it was fixed? So idk I would try that
And my phone also has horrible signal cmpared to my hero, and the 3g speeds and ping are horrible compared to what I got on the hero, and also apparently there's a cap of 1mb/s upload on the epic on 4g
Sent from my SPH-D700 using XDA App

They capped the 4g upload speed? I don't have 4g in my area but that sucks.

to the OP..
try ##786# <reset> <enter MSL>
let it go through it's paces.. it will factory reset BUT.. after reset, it will perform hands free activation, then reboot, then update your PRL, then restart the radio, then look for software updates.. (this will also most likely fix GPS if you're having problems with that too)
Hope this helps
EDIT: for the 'getting stuck in landscape mode' i have encountered this on occasion as well.. seems like the settings for 'use sensor to auto rotate' or something like that in your launcher or in menu > settings> etc.. might be conflicting.

3G during call?

I could've sworn that I used to be able to get 3G data while talking on the phone ... but for the past few weeks that hasn't been working!
Am I on crack, or is there something I can do?

You were never able to use 3G data while on the phone. It is a limitation of CDMA. You are able to use 4G while on a call though.

unfortunatly, with cdma networks it is impossible to share data over 3g while on the phone... BUT you can however be on wifi, or even 4g while on the phone and be on the internet.

It's a limitation right now but not one overall. SVDO will take care of that problem but it hasn't been implemented yet on any carrier though I hear HTC Thunderbolt is supposed to be able to do this without 4G. But I'm still a skeptic.

This could only happen if you were also on wifi or 4g. Actually, it may have just been that the page you were trying to load was cached.

Well none of that should be going on, something else has got to be causing issues. The majority of Evo roms are very stable, in my experiences. What rom are you having trouble with?
To answer your question, the easiest way to unroot is to download and flash the unrevoked s on tool (only if you've ever used unrevoked forever, which most likely you have). That'll turn S on in the bootloader. After that, download an RUU from here on XDA, and run the RUU from your computer. That will flash you back to stock, unrooted.

Nothing you've described should be related to rooting, unless you've flashed something that isn't playing nicely. You are of course welcome to go back to stock, but maybe post what you've flashed and what you were hoping to accomplish by rooting. We may be able to give you some guidance.

Rooting your phone shouldn't have any affect on your phone that way unless you installed or horrid ROM. Check the modem you downloaded with your ROM, maybe you could use a better modem?

Why did you post two nearly identical threads? One would've been enough to obtain an answer.
But then again, so would the search button.
