Can anyone tells me about the advantages and disadvantages of unlocking bootloader? because i saw some people said that they regret unlocking it. So whats the point of unlocking it? thanks for anyone who willing to explain.
I'm just an user but from what information i got so far (pardon me if anything is innacurate):
Unlocking the bootloader may open up a series of improvements that were not possible before without workarounds, like having a proper custom kernel, a proper Cyanogenmod version etc. Maybe even real multitouch or 16 million colors are possible, but this is a bit harder since someone will need to write new drivers, and it's highly unlikely this will happen but... who knows?
But to take advantage of unlocked bootloader you need to DEVELOP for it first, for now it's like having root enabled without any root app available for it. Also, bricking the x10 was impossible, you could always go to flashtools and reflash your firmware and fix it if you screw up, but with unlocked bootloader there's a chance of actually brick it for real, so you must be extra careful.
Some people are so eager to have the latest novelty that they'll do it first and think about it later. But it's a positive advancement for sure, i'll be lurking the dev threads to keep up with the news.
Hi Everyone!
Just want to start off by saying I’m new to the Atrix, but not new to the forums or android itself. I’ve rooted and flashed ROMs and kernels on other devices for myself and others, but the Atrix seems different from all those, so I have a few questions that I couldn’t find definitive answers to (and yes, I know where the search button is).
First off “unlocking” the phone seems to be more of a risk than I am willing to take, considering I’m doing this for a friend.
So I realize I won’t be a able to flash custom ROM’s, but what can I do after rooting?
Can I even get CWM?
Can I flash a kernel that lets me overclock?
Can I do OTA updates? (I hear ICS is coming to the Atrix soon, which is why I’m not worried about custom ROMs at the moment)
Once I OTA update to gingerbread will I be able to unlock the phone down the line?
Also what are some other things you guys say are a "must do" for this phone?
I know I’m asking a lot of questions, but any help would be greatly appreciated (and yes, I know where the thanks button is too)
You can unlock up to and including GB 2.3.6. How do I know cuz I did it myself.
Second you are very limited on what you can do until you do in fact unlock your bootloader. CWM can only be installed after your BL is unlocked.
Finally there's a few YouTube videos that show you step-by-step instructions on how to do this (even on GB) so it's really not that bad. Just watch them a couple of times, go slow, and most of all make sure your phones battery is charged. In the end once you unlock, you'll be glad you did...

Thanks for your answer, you've convince me to unlock it, but I have one more question.
Since my friend bought the phone new off amazon very recently is there a chance that unlocking the bootloader will be blocked, which I've seen other users saying.

No, use the following link to unlock the bootloader.
http://forum.xda-developers.com/sho...r UNLOCK/ROOT for AT&T 1.26/1.57/1.83/4.5.91 [UPDATE%2007/31/11]
Follow everything the command say. Make sure at no point do you take the cable out, if you are asked at any point to select a command on the phone but it does not let you just carry on with the process. It worked for me. Mine was locked to Gingerbread 2.3.6 build 4.5.141

One thing to consider though is that you´ll probably void the warranty. That would be the case in Brazil. IMHO, the benefits of rooting/unlocking far outweighs the loss of warranty. I would only let my friend know that even though it doesn´t happen very often, things can go wrong and you cannot be held responsible for any demage...just like we see in each every custom ROM disclaimer.
I want to buy one m8. what is the difference between at&t factory unlocked and international factory unlocked version. can i flash roms in international version thread on at&t factory unlocked model directly??
Yes you can flash any rom you want from the international thread. I am currently running Android Revolution.

The 3G and LTE band compatibility is different. Do you intend to use on the AT&T network? If so, the "international" (EMEA) version is compatible with AT&T's 3G bands (850 and 1900 MHz); but lacks both of the LTE bands used by AT&T (700 and 1700 MHz) according to this: http://www.gsmarena.com/htc_one_(m8)-6074.php
Not band compatibility is set in hardware, and cannot be changed by flashing different software (ROM, radio, etc.). This means the EMEA version cannot be used on AT&T's LTE network, not matter what you do.
If using on a carrier besides AT&T, I'd check the band compatibility with what your carrier uses. Even if the AT&T version is compatible (with you carrier), I'd probably recommend the international version over it (if compatible as well). The AT&T version is loaded with crappy AT&T bloat and limitations. For instance, WiFi hotspot is blocked, so bootloader needs to be unlocked and the phone rooted in order to make it work on other networks.
Plus, there is the ugly AT&T logo on the back.
Just thought i would bump this thread instead of making a new one. I bought an unlocked at&t htc one m8 off of ebay that i plan to use in another country (i study abroad). I already checked that the frequency bands are compatible, etc. Here's the thing, i don't want my phone to have anything to do with at&t other than the logo in the back. In other words, i want to make it as similar as posible (if not exactly the same) to the international unlocked version. Is this possible with just software changes, etc? (i've read the phones are the same in terms of hardware). I want to remove all at&t bloatware and limitations. can someone please give me quick explanations of what i need to do or point me in the right direction? I'm not new to xda or rooting, but the only smartphone i've ever had is a samsung vibrant (which i've rooted and flashed roms countless times).. this is my first htc phone, so im not very familiar with htcdev or s-off.. but i learn quickly.
I would really appreciate some help

I have the ViperOneM8 rom installed. What is even cool is in the tweeks, you can change the AT&T bootup and logoff screen to a viperone screen. And change the AT&T logo in the pull down menu to any picture you want. s-off isn't really needed unless you plan on changing the kernel.

What you describe is easy to do by just unlocking the bootloader, installing custom recovery, and flashing any international based stock rooted ROM or custom ROM. I basically have done the same, as even though AT&T is my carrier, I absolutely hate their branding, non-standard signal icons, bloatware, and limitations (particularly Wifi Hotspot/tethering).
As the previous user already suggested, learning and reading is the best thing for you to do. Don't proceed until you have a good understanding of the concepts and process. My Index thread (specific to the AT&T versions) is a good place to start up reading: http://forum.xda-developers.com/showthread.php?t=2751432
Great, thanks for the information and guidance guys. i'll definitely spend the next couple days reading before rooting the device, i can't afford to brick it. Any other tips or advices as to how to go about rooting, etc?
Developer build device and ATT device are same exact hardware, ONLY difference is ones sim locked and other isnt, bought 2 developer device from [email protected]'s both run fine on ATT networks...

no additional advice. I think red point has a wonderful index that should work well for you.
I just wanted to tell you what a wonderfully refreshing attitude you have . Feel free to PM me anytime if you have any specific questions.

If you look at my Index thread I linked above, the first item under "Unlock Bootloader, ROOT, S-Off" is an excellent step-by-step guide to rooting. There really isn't much I can't add, the guide is so thorough. But I'd still advise to read around and make sure you fully understand all the concepts and steps, and not just blindly follow the guide.
If the goal is to install a custom ROM, you can stop before the step in guide where it says to flash SuperSU (after flashing TWRP), and just put a ROM on the phone and flash in recovery similar to how you have done in the past. The guide is written with the intent of staying on the stock ROM and rooting.
One tip I can give, is that you may notice there are some Toolkits that attempt to automate some of the process (bootloader unlock, custom recovery, root, etc.). I would actually recommend avoiding the use of these. Reason being, the steps aren't actually all that hard to do "manually", plus these toolkits (while well meaning) shortcut the learning process, and rob you of a valuable learning opportunity.
I'm assuming OP doesn't want a custom ROM or root. Just to convert the AT&T branded model to a stock unlocked model, and still get OTA updates. This is possible. You need to unlock the bootloader, get S-OFF, and then follow this guide (you can skip step 1, changing MID): http://forum.xda-developers.com/htc-one-m8/general/change-wwe-m8-to-dev-edition-ota-t2826567

Yeah, I plan on doing it manually. Thanks for all the good advise man. I'm liking what I see in these forums, I'm glad I landed here.
Sorry it took me this long to reply guys, I have been very busy in the past week. Time to learn me some HTC one m8.

One last question guys, hopefully somebody can answer me. I've already read a few topics on the terminology used (s-off, ruu, htcdev, etc.), and things don't seem to be too far from what i thought they were. I'm ready to root and flash a custom rom, but here's my question:
I'm a very methodical person, i like to know what I'm doing and that it's the right way to do it. When i flashed a new rom (or rom version) on my samsung vibrant i would do a full wipe (factory reset, clear chache, clear dalvik cache, format system, and format data) before flashing, then i would flash the rom, and then i would flash the rom on top of itself without doing a full wipe. This method worked for me for over 3 years and kept me from getting common bugs some people complained about. Is it fine if i do this with my m8? (i mainly want to know if it can cause problems).. What's your common flash routine?
Thanks for the help guys
I am simple, I do what you do except the double flash.

What you've stated is fine. Although factory reset already wipes data, cache and Dalvik, so its a bit redundant.
I'm the opposite of methodical (at least in the way you describe). I like to get things done with as few steps as possible (while still doing it right). I've similarly been flashing ROMs on Android devices for 4 years (4 HTC devices and 2 Samsung). But I hardly ever wipe system (flashing a ROM does that by default) and never double flash, and I've never had any issues I would attribute to flashing methods.
Some folks will swear by wiping system for every ROM flash, but honestly while there is nothing wrong with it, I don't believe in it and almost never do it (unless sometimes where the ROM specifically says to do so in the instructions).
On the other hand, there is nothing wrong with redundancy, and if you like to be methodical and thorough I would say just keep doing what you have been doing.
Hi there,
i hope that i will get better answer here.
My question is that i have m8 cell htc, but the problem is i dont know how to check what software was intalled in it at beginnig, i installed at&t marshmallow but want to know weather it was of at&t of international and device does not have any icon on the back of the device. thanks

Do fastboot getvar all, and post the results (delete IMEI and serial number before posting) and if we look at that info, we can probably determine what version it is.
Is there a way to unlock the bootloader like the note 3 and 4?
Developer of TrentsROM here. It's been a while but I would also like to know this as well.
Ghettoroot for root. No unlocked bootloader, looking like it's just not gonna happen. You could always use Safestrap I guess.
As I have said to TheRock40359,
put some work and let your valid links/findings/research to the thread I made.
I am personally still in haze but in all the research I see the small cracks in all these schemes made to make owner lives worse for no good reason now.
This device is a s3 derivate. So researching s3 stuff as well.
I wanna make it happen.
Lets move over to "my" thread for that.
from what I read, if you have the 4.3 update (MJ9 firmware) you will not get an unlocked bootloader.. if you have anything before that (4.2 / 4.1 etc) then you can use CAUSUAL to unlock and root your device.
does anyone know if the ND7 (4.4.2) firmware has a bootloader that we can unlock?
Hello. I came here for help. As i no longer focusing for phone rooting, i'm not able to switch back to stock rom for Mi 9T. Currently i have old MIUI 10.5 by xiaomi.eu 9.8.1 . I want to switch back to stock, most up to date version of ROM for this phone. I would like to ask how to do it. I'm pretty sure i need to update my firmware before flashing latest stock rom but i don't know which firmware. Can somebody post here up to date manual with steps how to do it? I also know about some MIUI program for Windows that can help but i saw many times it just hard bricked the device. I would appreciate some experienced user to tell me what to do.
I'm really sorry to ask here for this (newbie help) but as i said, i'm out of it for like 2 years now.
PS: It would be nice to don't have anti-rollback protection (just in case)

As your bootloader isn't locked anymore the whole thing is less risky.
