I recently unlocked my phone and rooted, I tried to flash CM7 Beta everything went well except when i rebooted it got stuck at the dual core screen. After trying everything, I decided to flash back to stock since cm7 wouldn't boot. My question is now that I flashed back to stock do I need to re-unlock my device? Does it stay unlocked? Can I just root it and retry CM7 again?
it happens to me too im reading on the forum but i dont think the bootloaders remain unlock cuz when u do the process it say that in the warnings
No one knows?
I read that once you unlocked you are unlocked forever because when you unlock it kills a fuse but you can cover up the 'unlocked' message so the average joe (such as ATT or Best Buy employee) wouldn't know you unlocked for insurance purposes.
I've also read posts though, like you, that state that it does re-lock the bootloader, so I am confused! I dont want to try flashing again though and end up with a hard-brick!
only installing official roms after unlocking will re-lock your phone or brick it. so if you can no longer see 'unlocked' when you turn your phone on then you will need to re-unlock the bootloader.
before installing any custom roms you need to do a backup. after that, do a full wipe/factory reset, wipe cache & wipe dalvik cache. then install your custom rom, reboot, wait anything up to 10 minutes, and voila!
theres no 'fuse' that needs blowing to unlock the phone, by the way. its all software based, and it can be re-locked providing that there is freely available software that allows you to do so!

Might want to do some reading and research. This has all been discussed previously in a couple of threads with links supporting a hardware unlock. Nobody has provided any proof of a software only unlock as of yet. Would appreciate if you posted where you got your information.
Cheers!

Can you provide a link that this is indeed a software lock?...

Sorry, when i say software based i mean the use of software (using programs to flash files) to modify hardware. hardware based unlocking would mean having to modify hardware, such as soldering or other means of modifying/replacing components.

Soo..
You start a new thread about a topic that already has 17 threads dedicated to it.
You clearly dont understand how the current unlocking process works.
You claim to know of a new sw unlock, but even after being asked a few times will not elaborate or give a link or other info about it.
And your making up your own terms depending on what makes sence to you.
That settles it. You win the lolthread of the day, and were not laughing with you.
let's simplify:
http://briefmobile.com/how-to-unlock-the-atrix-4g-bootloader
This unlocks the bootloader through the use of software, does it not?
http://tinyurl.com/6gwycaq (explains what a bootloader is)
Plus... I didn't start the thread. You might need to do a little reading on that.
I've clearly unlocked, rooted, and installed a new ROM on my atrix (i initially used the gingerbreak app to root it, but decided to change the ROM at a later date, so unlocked it fully)
I don't claim to know of a sw unlock. I merely stated that software is used (RSD lite, drivers etc) to carry out the unlocking procedure.
Oh, by the way, it's "WE'RE not laughing with you" (not very nice ) and "YOU'RE making up your own terms". Little bit of research for you, if you want

I think you're mistaken, it's a hardware lock. There has not been a software only solution shown. Since I have gone through the steps you described, and then re-unlocked my bootloader, the two processes were different (unlocking vs. re-unlocking), meaning that something changed when I unlocked the bootloader.
http://en.wikipedia.org/wiki/Antifuse#Antifuses_in_integrated_circuits
Trust me, this stuff is in all the ICs that you use.
Ok then, i apologize for not doing my research
I just ASS-U-MEd that if it can be re-locked then there is no modification taking place to the hardware itself (such as blown fuses - I'll admit though I only recently heard about eFuse's/Antifuse's as I've never dealt with them before, and therefore didn't know that the Atrix had them)
Thanks for the info.

reunlocking is the same presedure which you did before. just you dont need to do the fastboot unlock oem.i did it and reunlock 2.3.4 telstra
Hey Guys,
I was wondering if there is a way to reset the phone so it looks like no rooting was done to it or anything along those lines.
I know I can relock the device but it will read "RE-LOCKED" in the boot loader. Is there any fix for that. Also Is there any way to unroot the device and flash the stock verizon boot and recovery images to it?
No way to not have it say relocked because we don't have S-off so even after back to stock ,Hboot will show Relocked instead of Locked.
Can relock by going back into the same folder you have the unlock bin and when you type in the CMD its something like Fastboot oem lock
Once relocked , you can run the stock RUU that is stickied on the forums and it will put it back to the stock Verizon version you had before you unlocked and rooted. There is a guide also on how to relock or else I know the info is on Htcdev site as well.
Thank you for the reply. I was hoping there had been a way to get it to just say locked. I am going to return the phone. Not really my cup of tea. I'm just waiting for the RUU to download then I will put that onto my device and hopefully they don't say anything.
Please let us know

Deadheartsbeat ... it would be appreciated if you would let us know if Verizon checks the phone AND if you ever get charged on your bill for the full value once it gets through Verizon's system and HTC's system (however they do warranty exchange). I have a thread going asking people to please report in (but, of course, 90% of the answers have nothing to do with the question asked):

PLEASE think about letting the community know how the Verizon warranty return goes once you are Re-Locked. Thanks

I'm not warrenty returning. I'm going for a full blown refund. If they try to charge me for the phone after I return it there will be issues. I will not let them charge me and keep the device. If they ask why I unlocked it I'm gunna tell them I thought I had to do that to install the app i made using the sdk.
I will let you know what happens though
Chances are if your returning it in return window and your just telling them it wasn't what you wanted they won't even bother looking in hboot. As long as phone is functioning properly when they turn it on and what not should be fine.

Hi, I literally opened the nexus 9 out of the box, powered it on & after choosing a wifi network it began updating, the device crashed during this update and now it won't boot! I've tried & searched for everything, anyone have any ideas?
Booting to recovery with HW buttons, wiping cache/userdata/factory reset - Nada!
Can boot into fastboot, no permission to flash as oem unlock is disabled!
I cant get into the tablet to unlock fastboot oem unlock within devOpitons or usb debugging etc, (com.android.phone has stopped on boot) black screen indefinitely.
I can't flash any images while it is locked
surely there must be a simple method?
desperate here
Return it
I'd just return it. I'm no expert, but I'd seek a way to avoid the update during setup and try to postpone it until you unlock developer options and OEM unlock. I'm not sure how you'd bypass the update during setup, but you're in the right place if it's possible.

Certainly it can. If it started to install the 5.0.2 OTA, there have been a lot of bricks.

Welcome. And FWIW: there's a button for that.
If I remember correctly you can still flash the stock images even with the boot loader locked. Its only custom images that google will not accept unless you unlock boot loader.

Bootloader has to be unlocked to "fastboot flash" anything.
You can sideload an OTA with a locked bootloader, but you have to be able to access recovery.

Indeed I'm still new to nexus devices. I've been flashing on Samsung devices for years so I'm still stuck in my Odin ways. Just got the N9 less then a week ago. The whole fastboot thing was foreign at first but I'm getting there lol. Thank you again.
So, long story short, I recently bought a Nexus 9 from ebay which arrived with factory reset protection.
I have spoken to both Google and HTC about the situation and both were of no real help except for saying a few things outright between them to give me good enough reason to believe one of two things.
That 1 - it is possible to flash factory images over a device with a locked bootloader
or 2 - it is possible to unlock the bootloader without having access to developer settings
Anyone have any experience with either of these possibilities?
https://developers.google.com/android/ota
Full OTA Images can be flashed onto devices with locked boot loaders.
You need to boot into recovery and select sideload update.
Yeah, I know how to do that, but that only goes for updates, doesn't it? I tried to sideload a previous build onto the tablet but it failed the procedure, so it doesn't really solve the issue and if I flash a more recent update I still get FRP :/ If I wanted to revert back to the 7.0, or even marshmallow, would that be possible? Or does that require an unlocked bootloader?

Those are full ota images, same as factory image. Meaning full package.

Ah yes, now I see your predicament. Unfortunately, there is no "there" there. You do need an unlocked bootloader to wipe the system clean with a factory image, and as you noted, the Full OTA Image will recover you from a system that won't boot, but it won't get rid of FRP.

Exactly Hence my questions as to how do the manufacturers wipe everything and flash the new image without unlocking the bootloader? Or will it always be a trade secret?...... Hmmmm

did we ever fix this? my bootloader is locked and no os installed. Was trying to return to factory and went thru all the flashing steps successfully then at the end locked the bootloader. Now tablet says "for development purposes only not for production use" and boots back to fastboot. It will not reboot at all

Never found out how they do this.... are you able to boot in to recovery? if you can do that you may be able to flash a recovery OTA through 'apply update from ADB'. Worth a shot

it's only a bad move if you make a mistake and can't repair it because your bootloader is now locked. But if it goes well then you're all set.

What's wrong with it?
Your V30 is obviously a used phone and previous owner had unlocked the bootloader.
The bootloader was locked back before selling or else you would see bootloader unlocked warning every time you reboot. Like I see on my phone.
If you think/know your phone is brand new, then there's an issue where someone unlocked the bootloader at one point prior to sale, but locked it back.
Requesting this be moved to Q&A. It's in wrong section.
Is it possible to make it official again? If not, I If it's not possible, I'il give it back. Thank you.

It's got stock firmware and the bootloader is locked back. It is official.
If you mean counter set back to zero, I don't know. That doesn't affect functionality whatsoever.
Your phone was not new, right? Used by someone else before this, right?
Yes it is. I bought a friend's device. Where can we see counter 1 or 0 Thank you so much.
