Evo Unroot Repair

So my Evo charger port has been broken for awhile and I finally have the chance to take it in tomorrow to see if they will repair it under warranty. I obviously have to unroot it for them to do this, since I'm on CM7 right now.
So I'm a little confused - I flash the PCIMG to unroot but after I need to go to a stock sense rom. The stock rom threads have been saying if I flash them, I won't be able to re-root my phone. They will probably just repair my phone so I want to be able to root it afterwards.
So what am I suppose to do in this situation? They said they would fix my phone in under and hour if there is a problem.

you will be able to re root again after you get it worked on, no worries. All of the Evo software that is currently available is rootable.
Unrooting is easy, and basically two steps. First, if you rooted with unrevoked, or ever flashed the Unrevoked Forever tool, then you first need to flash the unrevoked S on tool. That will turn your S on. After you flash it, go to the bootloader, and confirm that your S is On. Once that's set, download the PC36IMG, and put it on the main directory of your sd card (not in any folders) Be sure it's named exactly PC36IMG (capitals matter, must be all caps). THen boot into the bootloader, and at that piont the bootloader should find the PC36IMG file, and ask you to update. Press Volume up to say yes. Once it's done flashing, when you reboot you'll be back on a stock sense rom, s on, and ready to take it in for service. You'll be able to root again afterwards using any of the current available methods. Good luck.

unfortunately there (to my knowledge) isnt a way to "repair" your charging port since this is a known issue with the HTC EVO.. i know because I work for Sprint. Unless they have someone there that can sauder your port back on or anything like that your probably just going to get a new phone. what i would tell you to do is unroot it, let them order a new device or swap one out and root that one..just some food for thought.

You must work in a call center.
Evo charging port durability is a known issue. Since it is hardware, a technician cannot reject the device due to being rooted, only if it is a software issue.

You're going to get a new phone, they cannot fix the port as others have mentioned. Don't worry about how easy it will be to root again, as you'll have a different phone anyway.

No i don't actually. and yes I do realize that unless its a SW issue we will work on it. I have done it many a times. If we end up having to swap the device out it must come back with the same SW as it left when you first bought it. Its just our M&P. some of our rf testers will not read rooted devices which is why we don't.. We are required to test every aspect of the device from radio to Screen.

[Q] Change ROM without using the display

Hi guys,
so, this is indeed my first post here. But the forums helped me a lot with playing with my Desire.
But now I have a problem for which I cannot find help anywhere, neither here via the search nor Google. I really hope you would be so kind to help me find an answer.
This morning I dropped my Desire Nothing really happened case, but the display won't work anymore. When I start it I feel the vibration that indicates the system start, and I also see the buttons under the display lighting up. But the damn display itself stays black. My best guess now is that the connector between display and motherboard might be disconnected/broken.
Since I hope to get it repaired over warranty, I think the first thing to do is to recover standard sense rom and unroot it. Otherwise HTC wouldn't repair it, right?!
So now the tricky part: how can I do that with an unconnected display? Is there any chance?
Or would you just risk it and send it in rooted and with a custom rom?
What's left to say: It cannot be discovered by my computer since I'm not able to turn it on.
I would really really appreciate any help or inputs on how to resolve this.
Cheers,
Pascal
PS: Since my Macbook Air got stolen 3 days ago, I can only answer from my office PC.

Just boot in to fast boot the run ur ruu then send it off

So, how would I do that exactly without being able to use the display or the pc?

or

Both methods require your minimum interaction.

Thanks!
Since I have no Win PC, this would be the equivalent for Mac/Linux, right?
And, how do I find out Baseband Version/Software Number?

I don't know much about OpenRUU, wait for someone else.
Second youtube video doesn't depend on your OS so I would suggest you that solution. However, it requires some interaction with your phone so...
If you're able to find a friend with Windows, that would be win-win solution. Basically you have zero interaction with your phone, just instal HTC Sync (drivers) and plug in the phone.
Since your phone is rooted do not bother about SW/BB version and use RUU ROM provided for your carrier which will restore SW and BB version to the stock. If your carrier sells unbranded Desire then go for the last official Froyo WWE:
http://shipped-roms.com/index.php?category=android&model=Bravo (2.29.405.5)
If your Desire is branded, find adequate ROM and possibly you'll need a goldcard too.

Thanks for your help guys.
Fortunately, I'm able to use a WinPC for a couple of days now. So, yay me
Unfortunately, it's not working the way I tried and wanted it to work. Here's what I did:
Downloaded, installed and started HTC Sync, plugged in my phone and powered it on. HTC Sync doesn't recognize the phone
Secondly I downloaded and executed the RUU exe, but it also doesn't recogize the phone.
Am I doing something wrong? Or is it just not working cos I'm not able to unlock the SIM?

Let me make something clear to you! If they do take and repair a dropped phone, they'll not even care to look at the software... Seriously. Warranty is for factory/shipping errors, which were caused by the manufacturer. Good luck convincing them how a factory fault suddenly destroyed your display.
But the easy way of going to stock is to get a sd-card reader and put a PB99IMG.zip in the root of the sd-card and start it up in bootloader mode. It'll flash it automatically.(no need to use a windows pc)

Well, it's worth a try, isn't it?! And to be on the safe side, I'd like to get everything back to normal before sending it in. At least to know, that the SW really isn't the reason why they don't wanna repair it.
And for this PB99IMG.zip, does it have to have exactly this name?
Thx

[Q] Warranty...?

Hi, Hope some1 can help me!
ok.. so i have been installing custom roms etc within the last couple of months.. the latest one i used was RCMIX3D Runnymede. This was working absolutely fine until one day the WIFI, the bluetooth, and the up and down volume keys all stopped working. When trying to turn on wifi it says Error. same with bluetooth... i have tried absolutly everything to sort this out. different roms etc.. the volume buttons don't even work in bootloader recovery mode!
I have now managed to install the RUU stock rom 1.32 using my laptop.. and still nothing works..
so i'm thinking must be a hardware problem?! and wanting to send to HTC for a repair... thing is.. i am wondering will they know i have rooted and installed custom roms etc?.. as i now have stock rom from RUU and will update to 2.3.5 via OTA on my 3g network..
Is there anything else i need to do? or have i messed up my chances to get my DHD repaired on the warranty?
Really hope somebody can help!! as this is doing my nut!
Cheers
Garry

hardware failure most likely if its not even working in recovery
my vol - doesnt work, im waiting for the day when the vol + goes kaput as well ,, a weak link in an other wise excellent phone
sometime i think engineers at htc went for lunch when it was time to make the volume rocker

Surely somebody would know if rooting etc would void the warranty?! i have stock rom and now unrooted......

I've just sent my phone back for replacement (long story short, HTC didn't repair my phone completely when they were supposed to, I had to take my phone back, didn't have time to replace it, and after some haggling I finally have got them to get a replacement sorted for me). I sent it back rooted, but with stock firmware (apparently Mac users don't exist, and I'm not installing a copy of Windows on my system just to unroot my phone).
Note that in the Nexus One warranty policy, there was a clause "h", which stated that rooting voided the phone's warranty. None of the phones since, whether that be the Desire or the Desire HD, have this clause. So it is safe to assume, and you have a strong point to argue, that rooting does not void your warranty, though if you come to brick your phone, of course, you won't be covered.
There is no other clause, apart from this clause "h", that covers software; it all covers hardware failure.
Finally, there are loads of stories that I've read of people sending off rooted phones for repair, and them coming back rooted, whereas there are few of phones being rooted, and being refused repair. Also, as you will know, to restore the phone to a standard, completely stock, factory fresh state, all you do is run the RUU; sending a phone back when a simple RUU restore is possible, to me at least, would not be economical, both in terms of time and money.

Get it back on s-on using Easy Radio tool v2_2 found here on xda http://forum.xda-developers.com/showthread.php?t=857537 and unroot and it should be fine.
However I understand you can´t use volume buttons, but well if you can root the device with visonary then you can do s-on using the tool I mentioned.
After that call HTC explain them your problem and send it for repair. I guess they will not find any traces that you used custom roms and also I heard from several people on www.tweakers.net who used custom roms and even didnt return it on s-on still got there warranty when they had it go for repair.
But most important don't mention about root or custom roms to HTC, aslong as you do that they will probably give the warranty and also HTC is not one doing the repairs it are external repair companies so it might be different for each country.
And yes if you would still have the custom rom on it would void your warranty, that's why I would always put it back to stock if possible, but about root I don't know, but before In returned in my phone for repair I just did a factory reset so that all data was gone and any traces off root.

Thanks for your responses,
I've since found a link on another site.. which shows somebody with the exact same problem and has got HTC to admit its this is a known fault.
http://androidforums.com/desire-hd-support-troubleshooting/300012-wifi-error-bluetooth-wont-connect-volume-button-not-responding.html
i'll crack on with the S-on thingy and call them tomorrow to send for repair or replacement
Cheers again for clearing that up

[Q] Explain to me why devs are unable to unlock the MJB bootloader

I've been curious about how the Bootloader is locked down and why it's so difficult/impossible to unlock. How does the mfg get the initial load onto the device when it's manufactured?
I read that this bootloader has some 2048 encryption and that it's impossible to crack. However, I feel like there should be a way to alter the systems firmware from a PC or some kind of connection to the device.

The way I read it somewhere is this,
There are efuses built into the processor/motherboard/memory/whatever that the new bootloader "blows" when it is installed. These efuses are necessary pathways for the older bootloaders, hence why they won't install. I don't believe the new bootloader is "locked" per say, it just prevents earlier versions from being installed. There is also a guide somewhere on these forums to recover your device from a brick if you tried to downgrade the bootloader. The new bootloader also doesn't prevent you from installing earlier roms, as long as they are flashable from recovery. Just do not try to use Odin to revert to an earlier rom. That's what causes the bricks, and although there is a procedure to recover, it doesn't sound easy and you end up back on MJB when you're done anyway. Hope that helped.
To whoever wrote the original post I referred to above, my apologies for not giving credit.

Thanks for the reply.
I'm pretty solid with flashing ROM's and such. I have been wondering if it would be possible to use a regular PC and some cool software to reset or reformat the firmware on the system.
Here is a link to the article I was reading:
http://rootzwiki.com/news/att-locks-down-its-galaxy-s-iv-bootloader/
Say I have brand new S3 hardware right off the factory floor. How does that system get injected with the software? When the factories get damaged or "Bricked" units back and refurb them, how do they do that. I know that you can use the SD card trick to jump your phone back to life, but there has to be some master way to do this

I don't have an S3, I'm on the S3 section because my mom broke her phone, so this is speculation based on when I owned an Optimus G:
There are qualcomm tools that can fix a lot more than Odin and Fastboot can, apparently, and manufacturers have access to those. When I had an Atrix 4G someone told me they replace the entire board when eFuses are burned incorrectly, but that sounds really expensive. Anyway, just my 2 cents, i'm out~

Is using the box safe?

Hi, my HTC one M8 eye isn't working for about one week now because I installed a wrong ROM on it. I tried many methods to get it back working but all have failed. I messaged HTC service center in my country and they said they can't support it even if I pay, since it was damaged in a non technical way. So I sent it to a guy in a Mobile repair shop and after two days he said, something is preventing any flash ROM from being installed and that he has to use the box method to remove the cid and make the phone accept any custom ROM. Now, I don't understand what was he talking about and I fear this would lead to more damage. What shall I do?
Thank you in advance .

The tech guy is referring to the dedicated boxes used to unlock ,flash or repair mobile phones.it should be safe as long as the guy knows what he is doing.But I doubt there's a box that could change CID without the phone being s-off.
Flashing a wrong rom should only result to a soft brick.As long as you can boot to fastboot you practically can fix it with official methods like relocking the bootloader and restore with RUU.
or flash twrp and install a custom rom.

Yer im pretty sure they cant change CID without S-Off, i was looking at buying the Xtc2 clip. very similar, but doesnt change cid, and as already said, soft brick=easy to fix, i fear he may be trying the old garage mechanic routine, go in with a flat tyre, come out with a new engine lol.
