[Nub Q] Unlocked Bootloader

For HTC phones I've always noticed that they release the dev. edition which comes with an unlocked bootloader and is therefor rootable. Then it must be true that the regular release comes with a locked bootloader, is there generally a fast update where someone finds a way to unlock it or is the best bet to just buy a dev edition?

In the US unlocking the bootloader from a phone you get from at&t etc. is not completely legal: .. that being the reason why they sell the htc one dev version there!
You can unlock the phone via htcdev though It's simple and officially from htc :victory:

WRONG. Please do not spread incorrect information.
Unlocking a bootloader on ANY DEVICE OR CARRIER in the USA is 100% LEGAL.

I remember reading somewhere that the HTC One X+ was given extra restrictions by AT&T so it was harder to unlock. Can you have a bootloader sent to a website/company to have it unlocked for a small fee?

No because if HTC dev is'nt avaliable to unlock bootloader than it's uasally xda folks that crack the bootloader and most xda folks share the unlock, plus if only some small company can crack the bootloader for a fee, the development would'nt be very good

[Q] - HTC One - developer edition required for custom roms?

Hi,
I'm getting a HTC One this week and I would like to know whether I need to get the Developer edition to use custom roms or whether the xda community has already found a way to unlock a locked bootloader on the standard HTC One?
I'm not worried about the phone being unlocked for carriers (I'm sticking with o2).
also, is there any other benefit of the Dev Edition or is it purely so it isn't locked to a carrier and unlocked bootloader?

Hi
Greetings,
If you.want to flash a custom Rom I prefer you get the developer edition
Yes we can unlock, root and install custom Rom on the normal HTC one.
Getting the developers editions will save your time in unlocking bootloader
Choices is yours:thumbup:

Hey, I just bought the HTC One Dev, it is on its way. I've been using iOS for a long time and this phone looks better to me than the iPhone 5.
Anyway, it will be my first Android device so I am a complete noob. Will flashing roms to Dev Edition also void the warranty? Just curious, I know that if done right, nothing will go wrong, just want to know if there is any other benefit other than 64GB and not having to root it. Another question, how can I root original Sense 5 to the phone if I later decide to sell it or just want the stock back?
Thanks in advanced.

Edit: Wrong thread

I got my htc one (non dev edition) and was able to unlock bootloader, root and install custom roms without issue.
no idea about warranty

What does "unlocked" mean for the htc one dev edition?

I have the 64 gb htc one dev edition and I thought I understood the unlocked part, but then I saw a bunch on here about unlocking bootloaders on the dev edition and that got me confused. Is the unlocked part referring to the ability to take it between carriers or the state of the bootloader?
Assuming I root my one, I still want dev updates (ota rather than flashing roms) but I also don't know what happens if I am rooted and then take an ota update. Finally, since I won't be flashing, I don't need to unlock my bootloader, right? Thanks!

Both.
Some people re-lock their bootloaders at some point and then "re-un-lock" later on, but in general you shouldn't have to worry about unlocking the dev edition in either sense of the word .

Odd way to unlock bell xperia z or t-mobile xperia z bootloader?

Hey guys,
I own both the bell version of the xperia z, and the T-Mobile version. I ONLY want to use them as glorified tablets. Basically like the Ipod touch version of the iPhone, I want to use them unactivated. For me, its all about customibility and I really want to unlock the bootloader. I know neither of these can be unlocked, but in theory, if i wrote the software of the global unlockable versions (c6602/c6603) which DO allow for unlocked bootloader, would I be able to do it? I know signal would be screwy with the radios, but i dont care since thats irrelevant to me. Any help would be great, thanks guys.

Short answer: Never going to happen.

So its impossible to write c6602/3 software to it? Longer answer would be nice : P

Sorry, you can't unlock the bootloader if a device says: "bootloader unlock allowed: no" which is if you have a branded device. If you try it, you'd better throw it away.

If u can root everything is possible. As long as there's someone who provide geeky solutions
And under your situation u don't need flash different rom as there's a way to install recovery without unlocked bootloader in rooted phone.

hey, thanks a ton for the responses guys! So, is there ANY possible way I can get cyanogenmod installed on either my c6616 or c6606? (Bell and t-mobile)w

I don't have your phones so I cannot guaranty but you can try my method.
I got a c6603 from vodafone, and use ota to update to 4.3.
Since the 4.3 cannot root and I dont want unlock bl. so I use these steps
1. downgrade phone by flashtool to a version which can be rooted.
2. root
3. install recovery in locked BL:
http://forum.xda-developers.com/xpe...cked-bootloader-cwm-recovery-6-0-2-8-t2187363
4. Choose whatever rom you like and flash it.
DONE!

You cannot use custom kernels on a locked bootloader, so you cannot run CM, PA, AOSP etc.
Stock based roms only. There's no way around it.

Awesome tips guys! Got recovery working and its all good- just ONE last thing:
are there any vanilla style roms out there like cyanogen that are stock based? I just want my pure android with some nice customizable features, no kernel updates or anything. Can you suggest any?

Questions before buying m7

Hey guys,
I've decided to buy a M7. Because my money doesnt last, i've to buy a used one
Well, I like custom Roms and want to install one on this device.
But before I buy one, I have still a few questions:
Are there any special versions of the m7 which dont can be unlocked / crom installed?
Can I install a crom only with a by htcdev unlocked boatloader? What I can with s-off, i can't with s-on unlocked boatloader?
Do i get a higher hboot Version with a higher Rom Version? So if I install 4.4.2 OTA i get the newest hboot?
Are there any differences between the hboot versions? Does a Rom runs better with a newer hboot or something like this?
How is the battery drain?
Thanks for your answers

Can't really answer all the questions but I'll answer what I can:
1. Depends where your m7 was from. Tmobile/Verizon/Sprint had some differences. It affected the way I had to root my phone. Flashing roms should be universal depending on the package you use.
2. Not sure what that means with the grammar bit. You need bootloader unlocked to flash a new rom. Most of them come S-on unless you bought an OEM which may have come S-off. You can flash roms with the phone S-on.
3. Higher bootloader versions seems to come from more later models of the HTC One from what it seems.
4. Bootloader versions seem to affect the difficulty level of being able to turn something from S-on to S-off more than anything for the average joe.
5. Battery drain depends on what you do with the phone and how much brightness/volume etc you were having. I play games on my phone now and I need to charge my phone (from about 10-25%) to about 70-85% about 2-3x a day. I play pretty often (rotating between brave frontier and puzzles and dragons and the like). I also don't charge 0-100% to conserve my battery's life. Also, it will depend on how well the previous owner has treated the phone's battery before it arrives in your hands. If they 0-100% it before many times, you can be sure the battery life is not going to be what was advertised.
Take my ansewrs with a grain of salt because I'm not a dev, but I just lurk and tried to learn to tinker with my phone. Hope it helps.

1) Dual sim variant
2) If u unlock the bootloader, you can flash a custom recovery and root. Even if S-ON, you can flash Cyanogenmod and all Sense roms. S-OFF is needed for GPE based ROMs
3) Only if you're on a stock unrooted One with a locked bootloader, OTA's will update HBOOT. But, if you're on a custom ROM, you'll need to manually flash the updated firmware, which updates HBOOT.
No, there's not really a difference between HBOOTs. Update them if you wish to. No compulsion
4) Battery drain is lesser on custom kernels than on stock

Okay thanks for your answers.
I read a bit more and I read that its only possible to change the cid with s-off. And the cid is important for RUUs. And for some brandings there arent any RUUs right? So its usefull to get s-off if I have a ****ty branding, otherwise its not usefull for me I think.
I've read there are problems with T-mobile brandings, what are their specials?
And because of the battery, I need for one day around 3h display on at medium brightness. I think I will use the arhd Rom. Is this possible ?

Tmobile is GSM. So, its nowhere as problematic as Verizon or Sprint. Plus, Tmobile hasnt recieved 4.4.3, so its on HBOOT 1.56 or lower. So, there's really no S-OFF problem.
I think you'll easily get upto 4.5 hours on stock kernel. Otherwise, custom kernels are also there which have better optimisation

Great thanks. And whats about the purple camera Problem ?Does it appear on many devices? Are newer devices fixed and havent this problem? And do I have still my guaranty for HW problems (like the purple cam) with a by htcdev unlocked device?

When there's moderate/low light, the camera is unable to pick up that original colour. It gives off a horrible looking purple tint. It appeared on quite a few devices, including mine.
HTC definitely wont fix it if its bootloader unlocked unless you have a developer edition. I RUU'ed the phone before giving mine fr repair. Service was excellent; within 3 days, they gave it perfectly repaired.
Im not sure if all newer models are fixed; if you're lucky, itll be alright

Well, that makes me contemplative..
Is the stock Rom very bad Or its useable?
Especially the battery drain interest me compared to a crom.
Because if I havent any guaranty after flashing a crom and there are such Hardware problems.. I dont know if this is worth.

You always have the option of returning to stock. I had a custom ROM on my phone when i noticed the issue. I RUU'ed the phone back to perfect factory settings. You will also be able to do the same. You can regain manufacturer support if you have hardware issues
No, the stock ROM is pretty good. I used it for 2 months before i rooted. The built in power savers work very well; there isnt a considerable difference between stock and custom ROM

I wouldn't say stock ROMs are bad for battery life. I still think custom ROM + custom kernel (ie elemental or bulletproof) gives much better life
