[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.

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.

It'll never happen. All you can do is do a nand backup using RA 1.8.0 to backup your wimax partition. The way keys are signed/encoded is a one-shot deal. Done at the factory. Though at the depot level they (HTC) reflash the phones with new everything during the remanufacture process.

I think I deleted my Android back up anyone have one I can use??

It doesn't work that way unfortunately - you can't use someone else's nandroid backup because the RSA keys in their wimax.img are different than yours. They are specific and unique to each and every Evo. I sold my Evo because my WiMax RSA keys got hoses and purchased a brand new one. I'd suggest doing that if you don't have a nandroid backup that was made through Amon RA recovery.

Ok so Sprint said that to get it to work again they have to flash it will that brake the root?

Sprint cannot AFAIK replace your 4G keys. That has to be done by HTC, and HTC only since they are the holders of the master Verisign key(s). Also any reflashing by HTC, or Sprint will remove root.

Oh well that's what she told me lol

Not a very honest thing to do... Please, this is not an attack on you, furrelkt. It's a message to everyone. It just seems more and more people are doing this. Everyone knows when you get into rooting/modding you are taking a risk. If you trusted some random person on the internet that you do not know and flash a radio and break your RSA keys, that is your fault. Giving Sprint the liability for your actions gives liability to all of Sprint's stakeholders. That includes everyone on these boards. We, as a community, need to start instiling a sense of pride and ethics into ourselves. Without it, we just corrupt eachother and take away from what this community is all about.

Sprint will simply backup and flash your phone and run it for tests. They will then look at your MAC and see that you have corrupted your Wimax files.
At this point if you have insurance, you will pay $100 as a warranty return.
Or with no insurance, they will offer you to buy a new phone. But remember that you still have a very functional phone just no 4G. Really 4G is patchy and uses the resources of your phone poorly. I use it but mostly don't.
Download CM6 for Evo, flash your favorite kernel and enjoy the experience.

I agree and disagree at the same time.
I will agree that if you start flashing files of unknown origin to your phone without really knowing what you are doing then you deserve what you get.
At the same time though -- this particular instance is a 100% software issue that can be resolved in 5 minutes once an EVO is back at the factory. True cost to HTC or Sprint is next to nothing outside of some frieght and paying some kid 10 dollars an hour to run EVO's thru an automated restore process.
I hosed my 4G RSA keys, but have not gone to the sprint store to try and swap because my EVO is pristine and just like the day it came out of the package. I take care of it dearly. I have the fear that if I were to get a refurb and back to square one, whatever unit I get would smell like ass, be scratched or dinged up, and some other kid would get my flawless phone after it's reflash.
I was never a heavy user of 4G anyways, it's in DFW, TX however I live about a mile outside of the nearest bubble of 4G.
Either way -- yes it's sneaky, but it's not as costly or "evil" as one might think if you are returning a phone that is physically 100% good.
Trying to get a new/free phone because of physical neglect though? that's cause for an ass whoopin'

HARDBRICK

Ok i know this is stupid. But can someone please tell me how to HARD brick my htc evo 4g, its got the latest hboot so i just need to know how.
if i do the 4.24 update and while its updating, pull battery, will it brick?

WTF? is wrong with you? lmao! Are you kidding?! wow. I don't know how to reply. lol. well, there is an app called wank-o-meter. go download it. You'll have fun with your hand tonight. :-D

If ur s-off u can do battery pulls while flashing radios...what is ur reason 4 trying 2 brick...just wondering
Sent From My Pocket

Because one, sprint refuses to replace my replaced evo.
it has no functioning camera ( blurry like a 50's tv)
halo affect from screen leakage
I am s-on. I dont know how but i got the 4.22 and 4.24 update doesnt show.
SO is it possible the software update if it shows begins and i yank the battery out, will it brick

go back and speak with a manager. but remember that you will lose your rooted phone. if you TRUELY want a new phone and will get one no matter what... then unroot your phone and set all settings as default. like I said. TAKE IT TO THE STORE! don't purposely **** it up worse. However, if you DON'T PUT A STICKER ON THE PHONE ITSELF NOTING THE CAMERA IS BAD, IT WILL END RIGHT BACK IN THE FIELD IN SOMEONE ELSES HANDS. because they don't care if they send a defective right back out.

its not rooted.
also i know they will do that. Howdo u think i got it

wtf. okay. then take it back to the store. find out if it is a corp or fran store. sounds like a piece of **** franchise store! tell them THAT THEY WILL do as you ask. it is a defect of the phone. then threaten you'll report them if they don't follow your orders.

Sprint customer service is who replaced it. The thing is they said it runs fine from their Provisioning test

you can already get a free upgrade. they're promoting it. But, I'd take the evo3d if you can get it early. lol. if my phone broke. I would get the evo 3d. but only if it breaks. yours is broken. hell. take the upgrade. BUT REMEMBER. there are SOOOOO going to be better phones in the next year. they won't let you upgrade twice.

[Q] Taking rooted EVO in for service

I have an EVO with a cracked screen that's running one of the CM7 nightlies. I need to take it in for service, but I was wondering if I should flash back to some stock ROM first. If I do, what should I download that will allow me to re-root the phone? If I understand things correctly here, the current Sprint image has not been rooted yet, so I want to make sure that I don't wind up locking myself out of my phone.

Flash the ruu for 2.2 and make sure when you take it in you make sure to tell the tech not to update your phone cause they will do it out of habit.

I get the impression that they mostly don't care. I originally took it in last month and the guy first asked if it was rooted (the lock screen was different), to which I replied yes, and he said something along the lines of "cool I rooted mine too". He then asked if I had insurance, and when I said no, he told me to sign up for insurance and come back in a month. Yet another reason I'm happy with Sprint

Eh, it is a hardware issue, cracked screen. You should be able to leave it as is. If you want, put a PC36IMG.zip of stock Froyo on your SD card in case they are ridiculous and insist on unrooting. Never S-On, they rarely ever check for it

[Q] How do I brick my phone

I kinda of want to intentionally brick my phone just so sprint would replace it. I have been having some trouble with my evo lately, it just started to reboot so frequently lately. I was running decks 1.2.1 and just thought it was the rom, so i completely wipe everything, reflash and same thing. I noticed when my phone rebooted it would get hot or warm, and gps did not work after flashing decks 1.2.1, trying to use gps would automatically cause the phone to reboot. Any rom with the vision gps drivers would cause phone to reboot when trying to use gps, only gps driver that would work was the cm7 drivers, mainly used the N39 one and that would work and I could use gps, but phone kept rebooting. So then i tried to flash the latest stock rom, but had same problem. Also tried to use myn's warm rom release 5, which was always so stable in the past and never had any problems with when i was using it in the past, but yea phone just would reboot at random when phone would get warm or just doing stuff. Then i flashed the latest radio, pri, nv, and hboot. Went back to decks but its very frustrating, i can not use my phone for a long time or it warms up and goes into a bootloop, then have to pull the battery and give it a couple minutes to cool down before i can pop the battery back in and have it not reboot immediately afterwards. So after all this i was just gonna try and brick it to see if i could get another evo, but yea i tried to flash a radio and battery pull but that did not work. Did i screw myself by flashing the latest hboot?

Why don't you flash a stock rom. See if it still does it and then go to sprint and tell them all the problems you're having

I did try a stock rom and it kept happening. That is why I was trying to brick it so they would just exchange it. If I take it to sprint I would need to flash a RUU right? Then deal with sprints b.s. until they exchange it.

I've never had a problem getting my phone replaced. You have problems with your phone. They will replace it. And yes, the ruu will return it to stock.

It sounds like a hardware issue. Sprint will replace it. Don't brick your phone, not worth it.
RUU to the latest update. Get S-On (there are a few threads with tutorials). Try to document your phone acting up if you can (I had an overheating issue with my old phone so I took screenshots of an app showing my phone 135+ degrees. Reboots, maybe video it, I don't know.)
