Poll: Htc dev unlock?

Are you willing to lose the guarantee, by official HTC metod, in order to have S-off or root rights?

Doesn't HTC method just make you loose software warranty ?
I mean, I think hardware problems are still covered after that.
see that on htcdev website :
It is our responsibility to caution you that not all claims resulting or caused by or from the unlocking of the bootloader may be covered under warranty.

I need confirmation on that though as I'm not sure

i think physical defects or damages due to unlocking the bootloader, then overclocking and frying the cpu or motherboard will not be covered..
however... if the screen malfunctions, it would be reasonable to uphold the warranty unless there are reasons to believe it is again due to end-users unlocking the bootloader. (ie, maybe the guy unlock the bootloader, overclocked the phone and the heat caused some circuit to melt due to excess heat and this caused the screen to stop working?)
many scenarios, just giving some examples of what i think would mean non-coverage by warranty..

Physical damage can be attributed to unlocked bootloader. Example, heating has destroyed your lcd pannel. Warrenty uncovered. In our case this is not the truth but, to get back your phone what can u do if not pay?!?
Maybe htc is too much honest or maybe not... anyway they have a strong weapon to not recognize it.

Why is my security still on (S-On) after I have unlocked my bootloader?
Your device is shipped with Security on (S-ON) to protect your system software configuration (such as the bootloader, radio, boot, recovery, system and others). After you have unlocked the bootloader, however, you will have lifted the restrictions on boot, recovery and system. This means you can customize boot, recovery and system images on your phone as you desire. You can easily see that you have successfully unlocked the bootloader by looking at the top of the screen when entering the bootloader screen. Security is left on to protect things like the radio, and SIM lock.
so, device still be s-on? no way to change radio and hboot? O_O

I will do it with an unofficial tool.
Hopefully the revolutionary tool will be there soon!
I don't want to wait..

If you want to send your phone to HTC, you can bring it back to stock before.
But if you did it with htcdev, HTC can see that you unlocked your Bootloader, so it will be difficult to get your phone repaired.- HTC just won't do anything but they will never know if you used an unoffical tool.

Sound good to me, I always like the option to go back to stock for these purposes so I'll wait too
Sent from my Transformer Prime TF201 using Tapatalk 2 Beta-2

You can go back to stock after using htcdev, too.
But your Bootloader will be signed of htc, so they know that you did it.

Yea you're right!Hope S-off will come then I don't need to unlock in HTC bootloader~

Has anyone asked the Revolutionary team if the exploit they used before works with the HTC One series and if they will support the device? I assume they will because they tend to follow flagship phones but you never know. Here's hoping we won't have to wait too long.

I'm sure that they are working on it..

As far as I heard you still have warranty even though you unlocked your bootloader.

Yes of course but if for example your processor is damaged, you will surely not have any warranty on this.

Us vivid users went through heaven and hell to try and unlock the bootloader/achieve s off. Only after some strategic calls to HTC did we even get the official bootloader unlock, we never achieved it.unofficially either. We still don't even have s off so no radio flashing and a more round about way for flashing kernels and recoveries. I really hope the One X will have an unlock bootloader option. HTC wasn't even planning on giving the option until six months after the release. It didn't matter though, our development and most the community was already killed off by the time we got bootloader unlock. Hopefully HTC learned a lesson or the people working on unofficial s off/bootloader unlock have some tricks up their sleeve...

I was just chatting with HTC and mentioned I had mine bootloader unlocked. He said it voided my warranty as that was stated on HTCDev, but I said HTCDev only says its void certain parts off the warranty.
But in e-mail I got from HTC they state, you do not get warranty when you are running an custom rom, so I guess we need put it back to stock and lock the bootloader.
Then there should be no problem with warranty.

Yes, there still is a problem. Never again will your hboot read "locked", it will only show up as "relocked", so you still aren't quite out of the water.

Yes that's true, but I believe you can just use your warranty. The guys in chat who say you voided it don't know what they talking about.
If you really send it in for warranty then they should just fix it. But best we can do is relock it.

Actually, a stock-looking rooted ROM will do the trick. I've heard enumerable amounts of people saying the people at HTC didn't even look to see if the device was rooted or bootloader unlocked. I really don't think they are that picky.

I think so to. But atleast I would load the original non rooted stock rom on it. I only get the bootloader from Evo 3D to get show relocked and under it still says s-off, but I guess that's from revolutionary and I don't know how to get rid off that, but I will just leave it like this.
I have heard enough stories that peoples HTC got fixed with an unlocked bootloader and some even with an custom rom. And how big is the chance someone really ever going need use the warranty?
I think its quite small. But I'm not going unlock the HTC One X i think as it should be fast enough even without an custom rom.
I don't want HTC to know it and we should have an unlock method that is fully reversible, at HTC Desire HD we had that, with on click you had it back s-on.

Confirmed. Unlock works.

I understand that unlocking your device via htcdev.com will irreversibly void your warranty, but is that also the case, if I unlock my device with the stuff from the revolutionary team ?
I never had a device, which could be unlocked that way. My first two android phones were Motorolas and they could always be converted back to stock, for sending them in for repairing or for selling them.

You probably can still revert completely back to stock, the point is that if you use htcdev.com they've got a record of the phone being unlocked (even if you return it to stock again), whereas if you do it yourself then revert it they wouldn't know it had been unlocked in the first place.

That sounds great, thank you.

Thank you !
Like the other I prefer another method...

i will also wait for revolutionary^^
luckily there is temp root so i can delete the crap i dont use
cant wait for it to come so i can flash the first coredroid beta on it^^

Temp Root isnt working...

If we use the htcdev.com or revolutionary HTC will find out that the phone was unlocked!

No. Revolutionary is reversible. But htcdev does keep a record forever. However, that doesn't screw you out of every single warranty like many think. Only a small number of software issues, otherwise you still have warranty. We will see how long many of you will wait for revolutionary before you cave in and unlock through htcdev lol. All of us vivid users never got anything other than htcdev unlock. All the devs working on s off told us that HTC made it a hell of a lot harder to crack the newer phones.
Sent from my HTC PH39100 using xda premium

About htcdev unlock. They log your imei and serial number, yes. BUT the only thing you'll get after that is the posibility to unlock your device. Once we get Revolutionary s-off and then the ability to s-on again, how will they know if you really used the possibility to unlock your device? There's a final warning so no evidence you finally used it
Hopefully revolutionary team may be able to use the htc unlock method

Any way I just unlock it now using htcdev
Because I want it to try the temp-root to see if it will work with unlocked but did not work.
As I understood with unlocking using htcdev I still have the warranty for the hardware or I just lost all the warranty?

So just confirming that the htcdev unlock does not let the temp root work?

I've got permaroot working with an unlock by htcdev. Wai for mike to update his thread

Unlock & root only with registration at htcdev.com

Considering the One X/S as my next device.
I read somewhere that htcdev.com registration (and bootloader unlock) will void your guarantee forever, and based on experience I will need HTC service at some point.
Did I understand it correct, that in order to unlock the bootloader and root, I would need to register at htcdev.com. There no other way?

From what I have been reading just unlocking your bootloader won't void your warranty. But HTC will be able to tell what software you have installed in your phone according to this post HERE
So it's really up to HTC whether or not they fix your under warranty if you ever decide to use custom ROMs.

Hmmm...spooky!
So even if we manage to unlock and root without htcdev.com, HTC cache what roms we use in a hidden folder that cannot be flushed. I'm sure HTC is not going to use such information at my advantage.
If that's really the case, I guess HTC is no longer an option for me?

When I used htcdev to unlock my htc legend I was required to send what is a unique device token to HTC before they send me a unlocker binary file, obviously to me that device token tells HTC exactly which phone has been unlocked and is stored in a data base somewhere, so if you send it for repair, even if you do manage to get your phone back to stock again before, the records will show that the phone has been tampered with.
That's what i believe anyway.

Sending the token means you may have unlocked your phone. They don't void warranty for just unlocking your boot loader.

There are only hardware solutions [which don't make a lot of sense for a common end user]. lg(e) tool & riff box both offer methods for s-off on gsm one v. A local repair shop might have one of these tools. I have a riff box, but that doesn't do many ppl very good. No soft-unlock; I agree with previous posters there.

Sure, as soon as I get cdma support for same.. I carry a Virgin Mobile [as of today].
The sticky part is you have to have a jtag tool.. found out medusa box also supports htc one v. Then, possibly even more sticky, you have to disassemble your phone and use testpoint to disable your emmc. Lots of people have totally screwed their phones not following that hairy step.. The rest is quite easy should you have and read your respective jtag support literature.

I totally agree with you. S-OFF really is not needed unless you're a true developer. And by that I mean, unless you are wanting to look at and tweak your bootloader and/or radio.. why does one even need S-OFF? The HTC unlock should work just fine for 95% or more of the people out there. Those that dare to need more... they'll just have to pay to play [or take that risk].

CDMA ver should got S-OFF , GSM yet no S-Off yet.
S-OFF is super useful for who want to do custom rom/kernel without breaking the warranty because you can unlock BL without via HTC unlock and lock BL again at anytime when you want to send it back to HTC service centre.

You can customize both roms and kernels with HTC unlock. The only restraints are as I mentioned before: your stuck on latest bootloader and radio cannot be tampered with [or switched to another carrier]. That's pretty much it. The differences in a nutshell.

Companies, including HTC, do make a limited number of S-off devices [typically for qualcomm developers or the carrier development teams]. These have occasionally been shipped out in error to regular customers. It is like finding a golden easter egg though, not typical. In those rare cases HTC might take phone back [to save face since ultimately was a shipping error] but typically s-off will void a warranty. Truthfully though, if you have a s-off device, one would rarely need to utilize warranty. 99% of issues out there can be fixed with software [patches, replacing binaries, kernels, etc.] Only time warranty is needed is when hardware fails; which, hasn't happened to me ever i the many devices I've owned.
Rob
Only hardware faults I've seen with this particular model [HTC One V] are bad/fried emmc chips and/or bad resistor from emmc. These typically come from people that have tried to defeat the emmc write protection [purposefully or unwittingly]. Unfortunately, this is why with these devices test point must be used [which shorts the emmc disabling the write protection] or indeed hardware damage could occur to your device [if your determined to try but attempt to write w/o disabling the write protection]. Do I believe many will actually partially disassemble their phone for s-off? Nope. Will I still work on and publish [safe] method if I can? Yep. Hardware failures on this device are denoted by dropping into qhsusb_dload mode [w/o invoking it properly through test point].

One more stuff about S-OFF. You can flash the rom with kernel together in recovery mode and don't need to flash the kernel via fastboot separately.

Thanks for your links.
But with S-OFF, you can remove the tampered status in bootloader.

I read it here from HTC One. You can even change it back to S-ON before you send it to HTC service center.

tampered flag not the same as checksum test, but yep [once s-off] should be able to remove tampered flag.
Some S-off solutions can S-on; Some cannot. For hope in the matter, always run a full dump [preferably on a clean, factory reset device] before you s-off.

Selling / trading in an S-off phone

I am looking to sell or trade in my m8 (with mazuma mobile, envirophone) etc, however, even though I have reinstalled stock unrooted software and recovery etc, I still get a message when I am setting up the phone that it is a "test device".
Does anyone know how I can get this of this? If not, will it cause any issues during the trade in process?
My device is officially unlocked via htc, and s-off via sunshine.

yea swappa makes more sense unless you need the money fast from the trade in/sell

I would tend to agree. S-off is getting harder as time goes on. Leave it S-off and maybe just relock the bootloader. If the buyer is into ROMs, they will appreciate how easy it will be to unlock the bootloader. If they aren't, they will never notice it is S-off.

Ok, thanks, so how would I go about re locking the boot Loader?
