Solution for rooting the U11 without unlocking bootloader (warranty void)? - HTC U11 Questions & Answers

Hi guys,
I am really interested in the U11 but unlike for the US, HTC Singapore is stupid about its warranty policy and confirmed the warranty will be void if the bootloader is unlocked. So before I decide to move to another manufacturer, I just wanted to make sure there is no workaround to keep the warranty.
On my last HTC (One M8 Dual Sim), the USB connector and digitizer both had to be replaced within less than 12 months hence I would really like to be able to rely on the warranty for this kind of issues.
Are you aware of an existing solution or someone who may be working on a solution that could allow us to root the U11 without unlocking the bootloader?
Alternatively, I read that "Magisk" can possibly change the bootloader state, what does that mean exactly? Could we possibly unlock it then switch it back to normal without showing the "Re-locked" status?
Thanks

I would really like somethimg like that as well - unability to root without warranty void drives me nuts.

I got the same response from HTC Czech Republic: unlocking the bootloader would instantly void my warranty, plus they said that warranty-keeping bootloader unlock is possible only in that one special case for US customers, the rest of the world voids their warranty by doing so :/
Rant on the side: I truly despise not being allowed to get root privileges without voiding the warranty - it is MY device, yet I can't control the system. I want to do MY own backups, control (or inspect) the data apps save to MY phone, and control the configuration of MY system. I really hate being locked out from even such basic configurations as the hosts file is - I'm effectively barred from some aspects of web development so that advertisements can be shoved down my throat

Same here, from SG. Anyone knows of any method to unlock bootloader without going through HTCDEV?

The short answer is no.

is there a longer answer that would give at least a little hope? On Moto Droid 4 root and some limited flashing possibility were acquired by exploiting a built-in app vulnerability, even though the bootloader was impossible to unlock. Is this really impossible here? And if so, why?

no Way?

[Q] Is anyone developing another method to unlock the bootloader?

I wonder if anyone is developing another method to unlock the bootloader. The one Asus delivers is instantly voiding the warranty and I don't want to loose it

There's no way to do that (at least not without the Asus RSA key ).Read this post from rayman or read the first 10 pages of that thread.

Nice little bit of info -- I knew it was encrypted, but AES-Rijndael and 2048 bits keys? Seems a bit overkill to me, but yeah, it is a pretty safe peocedure this way.
Indeed this means no chance whatsoever of unlocking without ASUS doing it for you. Definitive answer, thanks Pretoriano!!

Sad to hear that. Now I have to think about selling it
Why would you sell it. You still have a warranty... Law in US states unlocking bootloader cannot and flashing your own software cannot void warranty. And if you issue is hardware related, then software is unrelated to your warranty anyway. Worst case Scenario, get a SquareTrade warranty.

No manufacturer will let you screw up anything for free and then turn a blind eye and save your butt. If you are that scared of using a technically sound procedure provided by the manufacturer itself, you probably even should not be looking at flashing custom ROMs at all. Just my $0.02.

What are you talking about? I'm talking about a flickering display or other technical defects which are NOT a result of unlocking or flashing.
Can adb read and write the bootloader? I'm wondering if we can do a comparison of an unlocked and locked TF700 bootloader and get something from that. I know the unlock tool can't unlock without the encrypted, signed response from Asus' servers, but can you overwrite the bootloader with one that's already unlocked?

You can't use adb for that and anyway you have to be unlocked before you can flash anything not signed by Asus.

In case you have problems with English, I will happily clarify my statement.
You asked: "I wonder if anyone is developing another method to unlock the bootloader. The one Asus delivers is instantly voiding the warranty and I don't want to loose it."
My reply to this was, and is, IF you do not want to use the unlock feature provided by ASUS -- which either works or not, but when it does, unlocks safely -- that you should stay away from unlocking or custom-flashing you device anyway. That way, you'll prevent screwing up your device in the process and subsequently letting ASUS handle the problem for you (or coming in here and go QQ ).
Furthermore, I do not get the point of getting hardware issues into the mix, because that is irrelevant: you can check for hardware issues before, while on the stock ROM. That way, if you find something -- and it sounds like you already have -- you'll still be under warranty.
So... question: what is your point?

So your point is, that hardware issues won't occur after months of usage? That's simply not true, defects can occur in a year or 2 weeks, no matter how perfect it is working at the moment. The speaker of my HTC Desire HD stopped working after 7 months. That had nothing to do with unlocking - it was just a hardware issue.
My galaxy nexus for example is unlocked, but I can re-lock my bootloader and flash the stock rom if a harware issue occurs (where I am not responsible for) and get it repaired by Samsung.
When I unlock the TF700, Asus instantly voids your warranty because you have to use their software which automatically sends your serial number to their server. So you have no chance to get your device repaired by Asus, even if a hardware issue occurs where you are NOT responsible for.
I don't want to return my device to Asus if I mess sth up.
Is this so hard to understand?

I'm saying that because if you poop your pants for what may, eventually, in a case of bad luck, go wrong with your device, you should not be taking any risk with it *at all*. The main reasoning behind ASUS' contention of the POSSIBILITY of revoking the warranty is clear: only tinkerers do this with their devices -- the majority of users will run devices in the retail, stock state. Tinkerers run a relatively higher risk of screwing up their devices, a simple to comprehend fact not to be explained or elaborated upon.

No, this is perfectly understood from even your first post -- the point is tht it is plain bull****. ASUS has, in many cases before -- and you can look that up in several other Transformer subfora in here -- repaired an unlocked device without asking questions, and without apparently caring whether it was unlocked or not.
You act as if you're living in a lawless third-rate (not necessarily meaning third-world) country whereas European consumer law -- and the German consumer law in particular -- is one of the most stringent in the world. If your device has a fault clearly attributable to a manufacturing error, there's no way ASUS is getting away with that -- they are obliged under European law to cover all defects detracting from user experience or device longevity/usefulness for the purpose intended for a minimum of two (2) years. It doesn't matter if the user shat his pants in the process or not.
Oh, if your speaker borking out was a manufacturing error, good for you to have HTC fix it, as they should have! However, 99.999% of the time, on a smartphone, a cracked screen, for example, is user error -- someone's wife should have been on a diet instead of sitting on top of his smartphone or something like that. In rare circumstances, it might be a warranty case, but if your device is of good quality, YOU and you alone are responsible for keeping it that way. And that's what I meant before -- don't screw up your device and then pass on the sh** to ASUS, going QQ to have them fix a previously perfectly good device. That's all.

I found this thread after searching for more info on the Device Tracker. To make a long story short, Asus has voided my Prime warranty saying my tablet has been rooted. After digging into them about how they got that information knowing I never sent my tablet to them, they said that they were able to get that from the devicetracker.asus.com website. Not only is it used to used to track the GPS of your tablet, but apparently they are able to get system information as well and something in there told them that my tablet was rooted. My tablet is not unlocked though. So be careful what you do.

almightywhacko said:
If you unlock your tablet's bootloader, you basically void your warranty.
Unless you know for certain that you never want to get an OTA update, or warranty repair again, don't unlock your Prime.
If you think you may have hardware issues in the future, and you don't want to buy a new tablet or pay to have them fixed, don't unlock your bootloader.
If all you bought the Prime for was playing around with custom ROMs, or if the only way Android has ever made you happy is through a custom ROM and you don't mind not having a warranty, then yes, go ahead and unlock your bootloader.
And yes. Asus knows when when a tablet's bootloader has been unlocked.

Moto G..Root it already.

Guys who fear that rooting will void warranty..
But what makes u think that the Service center guys will look if the bootloader is unlocked or not
Lots of people give phones with CM and other custom ROMs flashed to the SC...and that too with a custom recovery...i think which may be needed by the SC guys for software update,wipe etc etc
i myself gave my rooted phone for replacement.. though reverted back to stock rom
If u guys think why dont i go ahead myself..i only reason im afraid of is ..if they have a particular QC test app or something before RMA procedure..which may auto generate the result such as
Camera - check
Speaker - check
Vibration - check
Bootloader - fail - not eligible for warranty
and they strictly reject warranty for the phone because of that..
guys experienced with the warranty procedure for Motorola phones please reply
I rooted mine. I don't usually have hardware problems. So... whatever
I've rooted mine, just keep in mind that you can't unlock the bootloader without getting an authorization code from Motorola. By requesting this code you accept the warranty loss.
Edit:
Motorola requires you to run "fastboot oem get_unlock_data". This data is used to calculate or read the unlock code from their database. Those lines should also be more than enough to blacklist your phone from warranty.
Bootloader status codes
I think I'll wait for a while this time a least four to five months..

I guess I automatically associate rooting with flashing a different rom. But yes, it's different.
Its a $200 phone and rooting is pretty much a necessity to fully take advantage of your hardware. Flashing ROMs isn't as much of a big deal anymore but rooting is where all the fun comes from IMO. If there's no issues with it after a month or so, just do it.
Well, except for those of us unfortunate individuals who rely on Verizon's rural reach. I've got the Verizon Moto G xt1028, and it's not unlockable. At least, not yet. So those of us who bought the xt1028 are waiting and hoping for a different root method. Or different unlock method. Or both, really. Alas, we're forced to run fully stock until then. I'd so love to put GravityBox and a few other root apps.
At first I bought the 8 GB Variant and unlocked it, rooted it installed a custom ROM and I didn't like it because it didn't have so much space,
so what I did was flash everything Stock back again and lock the bootloader and I traded it against a 16 GB Variant and payed an extra 30€.
Now, I don't really care about rooting and custom roms anymore, I use the Stock Firmware from Motorola, latest of course so I get all official OTAs and all Motorola Apps, they probably know how to make everything for their phone so I'll just use it as it is.
In most cases they'll just look for the splash screen to say the warning message but we all got the logo.bin flashed. Worst case scenario they'll check through fastboot.

You mean unlocked ^^
If you flash software which will could cause a hardbrick or any other hardware failure then, for my knowledge, your warranty might be gone.
The reseller can only refuse warranty if he can proove that damage is caused by rooting, flashing etc.
Law expects that an failure in between six months must be from the beginning.
But after six months you have to proove that this failure was there from the beginning. This can be very tricky.
Only unlocking bootloader or rooting will not void your warranty in the EU. At least not the one which is given by law.
But the manufacturer warranty, which is an additional service of the company, can be voided.

True, unlocking the bootloader will not void your warranty. Damaging your phone while trying root it, 'may' void your warranty if the seller/manufacturer can tell, and can prove you caused the damage

Thought I should clarify this. If a problem occurs with the phone in the first 6 months, the responsibility lies with the manufacturer to
a) Repair
b) Replace
c) Refund
d) Prove the problem does not exist.
If a fault occurs AFTER 6 months, but before the end of the manufacturer warranty. The manufacturer must:
a) Repair
b) Replace
c) Refund
BUT the manufacturer is within their rights to ask the customer to 'Prove' the fault exists and that they did not cause the fault through misuse etc. Usually this would require an engineer or technician report. In reality sellers will almost never do this.
Note: In the UK (and maybe rest of europe) the sale of good acts requires items last for a reasonable amount of time (not just the warranty period) this is I believe 6 years.
SO technically you could claim for repair even up to 6 years, however the responsibility will be with the consumer to prove the fault was in design and manufacture and I 'believe' that it occurred in the first 12 months since purchase. (Very hard for a consumer to prove this)..

Not sure what you mean by 'warranty given by law' vs 'manufacture warranty'. The manufacturer is required to give a limited 12 month warranty on all goods as per the sale of goods act. A lot of manufactures will give an 'Additional' warranty, or a warranty that covers a longer period as standard. Samsung & HTC = 2 years, for example. SO, although they only require to give you 1 year, once you have bought the device, with teh 2 year warranty, you have entered a contract and they must honour the full 2 years...
Actually the first 6months is called workmanship warranty. Its unconditional warranty as long as there no blatant damage to the device. If you have tempered with it, then you go into the standard warranty clauses. Which it is then up to the manufacturer to decide weather they will repair it for you. Sometimes at a discounted price when it is in fact your fault. But if you have blatantly damaged your device, you wont be eligible for a warranty. If its software related though, they could give you the benefit of the doubt.

EFuse - This is, why i don't like it.

Hello, everybody.
@Moderators: If this thread is irrelevant, please let me know the reason.
When EFuse was released on the Galaxy Note 2 and the S3, not many people knew about this.
The Knox-Counter is just software-based and resetable, so it's not a problem.​
The idea behind the EFuse is rather good.
It will make your device much more secure.
If you root a device, you'll lose some software features (like Samsung Pay/Fingerprints on S6, KNOX, etc.). This will happen due to several security reasons .
But a huge problem is, that it makes you to feel very restricted.
Well, it would be no problem, if this EFuse was resettable.
...But if the EFuse is triggered, the EFuse-Chip will take physical damage (short circuit), so you'll lose some software features.
But the worst thing is, that you can't revert the EFuse, without replacing the motherboard of your phone.:crying:
That software-based KNOX-Counter is easily revertable. But EFuse can be used, to detect, whether the device was ever rooted. So a triggered eFuse will cause your guarantee to die forever. And some software-features also will be gone, even if you Unroot the Device.
EFuse would be a better idea, if it was just temporairly activated, when the device is rooted.
When the device recieves an unroot, efuse should reset, but it does not.
The Knox-Counter can be resetted manually, as it's no physical hardware.
A triggered Efuse means: You'll lose your guarantee and some features of your phone - for ever - unrevertable.
What do you think about that? Let me know by posting here and/or voting on the poll.
As far as i know, Flashing some software also triggers the eFusee
A better solution for eFuse
I can understand, why some software features have to be disabled after Rooting the Device or Flashing some software, but here's a better solution:
Flash
Flashing Software only disables features, until this software is uninstalled again.
OR: KNOX, Samsung Pay, etc. is only disabled, while a flashed software is running. After taskkilling it, knox and pay come back again.
Root:
Only disable KNOX and PAY - while the device is rooted - enable it again, when the device recieves an unroot. (Don't disable features forever
Avoiding the EFuse-Trigger also restricts the Backup Capatibilities.
Yes i know, you can't be secure enough, but freedom should also have it's place, as long as EFuse is secure enough. And it's secure enough, if it is just temporairly triggered.
But i think, the main reason, why EFuse isn't resettable without motherboard replacement is, the guarantee. Manufacturers can see, whenever something like root/flash ever happened.
Trapped
Because of EFuse, i'm pretty much trapped.

eFuse, by design, is irreversible. Designing a "reversible" eFuse would pretty much have no meaning - it would be like making a safe that can't be locked.
The eFuse has a great role in Samsung devices, but the WAY Samsung uses them (warranty void, if ever triggered, you can't use a lot of features) is not great, actually, it's far from great.
Instead of eFuses, I'd suggest using a different mechanism, something used in the Nexus devices - lock the bootloader, make a bootloader unlock code generator available, and check bootloader status. While unlocked, NAND is not encrypted, system partition is not protected, etc., and specific features are locked. If the BL lock is reactivated, do not boot until a valid stock firmware is flashed, then reactivate the disabled features.

EXACTLY. While the bootloader is unlocked, access to KNOX and Samsung Pay etc. should be denied. Flashing and Rooting is only possible with unlocked bootloader. But the bootloader can be locked again anytime.
The only problem is the WIPE in the nexus devices.
EFuse-Such a horribly bad Idea.
They had to do something to prevent it being reversed. With all the idiots returning devices because they messed it up to a non Bootable state, this allows them to see if it was their fault or some idiot messing with things that they had no place messing with.
I rEfuse to buy anything with Efuse. :silly:
No thank you.
Most devices shipped nowadays have some sort of Incremental fuse. Whether that fuse is checked by software or vise versa, is another story.

Agreed. Then I stopped using Samsung devices right after they lied to the dev community

Yes. But who the hell wants that? Nobody.
On Nexus devices, unrooting and bootloader-locking the device will recover the Warrenty.

Technically incorrect, rooting/unlocking bootloader voids warranty - once something us void you can't legally unvoid it. Just because you can unroot/relock bootloader and make it look like it wasn't tampered with, doesn't mean you recover warranty - but it becomes your word against Google/supplier.
I'm sure in most cases with the Nexus it's not cost effective to determine if any tampering went on, but I'd imagine if for example someone built/deployed an aggressive OC'ed kernel and burnt out the CPU there'd be questions asked during an RMA.

[Q] Should I unlock my moto g bootloader...

So I was just thinking of unlocking my Moto g and rooting it. Is it possible to get warranty after locking my Moto and unrooting it...?

I have heard some from Europe say that they can get warranty even after unlocking. I don't know about that but I know that here in the US, once its unlocked you're out of luck. My 2nd Gen was unlocked but I got a warranty replacement 2 times because I purchased it from a retail store and got their extended warranty. It was worth every penny and I would have done the same thing with the G3 except the store wasn't selling them.
It will still show it was unlocked at one time even if you relock it. Your warranty will be voided for all software issues, but you can still claim warranty for hardware issues like a bad speaker, or broken power button.

Yes and no because it depends on whether a problem can somehow be traced to software and that is entirely up to Motorola. I always go on the theory that its probably my useless piece of plastic if it breaks.
BTW to the OP, you don't actually have to unlock it to void the warranty. Once you request the unlock code, Motorola considers it unlocked, whether you go through with it or not.
Whether you actually unlock or not, I do strongly recommend going into Developer Options and enable OEM Unlocking, unless there is some security or other reason not to do it in your case... it might not mean much now, but if you have an issue later where you phone will not boot, at least you CAN unlock if you need to. If you do not have then option enabled, unlocking is impossible.
Enabling OEM Unlocking does not unlock the device or have any effect on your warranty, but does allow the bootloader to be unlocked at a later time if needed. Since Lollipop this is an extra security measure added to phones that are unlockable.
If you've bought the phone from Best Buy & bought their protection plan, you can unlock the bootloader & root all you want; they only care about hardware modifications.

That's great means you don't have to worry about any problem caused expect hardware modification which you will not do... I guess. If you buy from best buy. But I bought it from Flipkart.

That's bad news your warranty is void whether you unlock bootloader or not simply requesting doesn't mean one has unlocked it.

Sorry, but they will not... if you filled out the form on Motorola's website to unlock and accepted it, your warranty is void, it doesn't matter whether you actually unlocked or not, relocked, or leave it unlocked, your warranty is gone even if it is obviously a hardware defect from the manufacturer that has no relation to it being unlocked. Sorry, but you agreed to it, and Motorola will hold you to it.
Now, if you bough the Moto Protect insurance or have a third party warranty/insurance, maybe... Check your TaC.
That being said, if you try to get warranty work done, I would be interested in your results, although I expect I know what they would be, it would be nice to hear one slip through, because up to this point on all Moto products (except the Nexus) simply agreeing to the terms and conditions off the unlock voids your warranty instantly.
@Arcade if you are currently in India. service center guys doesn't check if ur bootloader is unlocked or not. u have to give them ur phone after reflashing stock and locking bootloader. and you'll get ur warranty. this method worked for my Sony phone in India.

Yes, I live in India.
But till now not faced any of issue. If faced then lets see what they have to say.
I too think that they would not check it. ?
I was just about to post a thread about similar question.
I went all through the steps to unlock bootloader except for the final step but I did click to accept and where it says it will void warranty.
My question was going to be if I have unlocked the bootloader does the regular warranty and/or extended warranty cover issues like, dead pixels, cracked screens, speakers and or buttons not working everything aside from hardware issues?
I dont see why they wouldnt be covered since majority of the time those issues wouldnt be caused by rooting and putting different roms on it.
Just wondering here and if someone had actual experience with this. Also would they tell you prior to sending it in through a RMA or after you send it in and boot it up?

Regular warranty, nope... doesn't matter what the problem is, that is gone forever once you clicked accept.
The "extended warranty" is actually an insurance plan, you pay a deductible for replacement... unless it specifically states that modifying (or similar verbiage) your device voids the insurance plan, then it should still work., but I have not seen those T&C.
So if i root my phone and my screen cracks, the warranty wont cover it?

Correct... sort of, unlocking the bootloader with Motorola (the only current way) will completely void your warranty,rooting or flashing a ROM is not relevant, it is spelled out quite clearly. Void in this case means you do not have a warranty anymore, so there is no warranty to get it fixed/replaced.
Actually, it doesn't matter if you unlock or not, if you accept the T&C on the website your warranty is gone... doesn't matter if you actually do it or not.

Alright good to know. Yeah its pretty clear in it stating warranty is void but wanted to see if physical issues were under that void. Now how do they check this prior to sending in the phone or after the phone is received by them?

Your IMEI number is on file from when you unlocked, there is nothing to "check" per se, as soon as you request an RMA or warranty replacement and put in your IMEI or serial number, they already know.

Question Unlocked bootloader data security

If I lose my phone or it gets stolen how secure is my pin protected data with an unlocked bootloader as opposed to a locked bootloader?
Pretty sure you have to wipe all to get rid of a pin, so I would say it is almost the same.

There are two schools of thought on locked vs. unlocked bootloader security (both which I quote below) that I saw discussed a while back on the subject. It may not directly speak on pin protecting your data -- they discuss some on how your device is encrypted behind your pin so even if stolen, it should still be secure (enough) -- but at the very least there are ways around EFS so your device might still be of some use and/or, maybe given enough time you never know what can happen; which is discussed a bit in the quote & discussion (in the thread they do it in) below...
You could click on either posts (they are made in the same thread) to follow the discussion more (they go on for a bit, but not to too much more of a degree)...

Everything will work perfectly with an unlocked bootloader. It will just give you an annoying warning screen briefly when powering on.
If you want to know about security risks, they're fairly small, and ONLY apply if your phone is handled physically by someone untrusted for an extended period of time, in which the only thing they could actually do is install a modified boot image. Under those circumstances, the device security has to be assumed compromised whether the bootloader is unlocked or not.
An unlocked bootloader will NOT allow a 3rd party to access data on the device, since it is encrypted and requires your security code to unlock.
Now, you can actually tell if they've rebooted the device, which they would HAVE to do in order to install a different boot image; the unlock screen (which they are NOT able to modify without resulting in boot failure) will tell you!
And I absolutely disagree that it is shortsighted to advise immediate unlocking. Nothing of real benefit comes from having a locked bootloader. Any sense of security you gain from it is smoke and mirrors. It can only be tampered with if someone has physical access, and if somebody has physical access, it has to be assumed compromised regardless of whether it is unlocked or not. If anything, your security is improved because it is now on your mind that it could potentially be tampered with, and you are reminded of it with the id10t warning every time it reboots.

Everything will not work perfectly. Let's be honest here. Look it up, some banking apps work mine doesn't. Pay will work one day and not the next. And if your bank finds out your account was hacked and your phone is unlocked and/or bypasses bank security protocols who will pay for the missing funds when they find out?
A missing device can be booted into a custom recovery and adb commands will be available to take everything on your device bypassing any security you have. With a locked bootloader that is not possible. So if you know your phone can be compromised you feel more secure? That is ludicrous and really doesn't make sense. I mean talk about smoke and mirrors.
Now that being said there are a lot of folks in your camp that say you're living a pipe dream if you think the phone is more easily hacked or info stolen. I understand that argument entirely and it's possibly correct to a certain degree. But to summarily say immediately unlock your bootloader if you don't plan on rooting because.. well just in case, is really disingenuous to a great many individuals. At the very least look up some articles on why to keep your bootloader locked, especially for someone that hasn't done it in some time, if ever. The beauty of Android is the possibility if you so desire. Just be conscience of the advice you give. Many years ago Chainfire said in his blog that if you have an unlocked bootloader and have financial apps on your device you're asking for trouble and you might want to rethink that. (not in so many words) That weekend I locked my bootloader and never looked back. I haven't missed anything.. well other than flashing MVK kernel for my 6a. ;-) But then I'd need root and that brings a host of other issues.
