Unlocked Bootloader

I think the flipside may already have a unlocked bootloader
as said here ->ausdroid.net/2011/06/14/an-update-on-motorolas-locked-boot-loader-situation/
"...This will be applicable to all devices that are scheduled to receive updates in the second half of this year, indicating the possibility that existing, locked devices may receive updates to unlock them in Q3 or Q4 2011..."
we may have an unlocked bootloader, we did just get the new update, but we dont have motorolas unlock process
im not sure what do you more experienced people think

sooo did Moto ever unlocked the Flipside's bootloader?

Not yet
not yet and im also watching for them to release the phones source code... motorola releases android source on sourgeforce

[Q] OEM unlock on Note 4?

(my browser spazzed and I lost my last post if it shows up as a double ignore the other one!)
I'm new to Android and finding it confusing so thanks for the help so far!
I have a 910F Note 4 on Lollipop and want to root it to get rid of bloatware and possibly stop ads (if I can convince myself it's ethical) btu I *may* want to custom ROM it later.
So far your help and my reading have taught me this:
-- I can root using chainfire in order to get rid of bloat and block ads
-- If after rooting I later want a custom ROM or Xposed I'll need to get custom recovery in which case I'll be able to add CWM or TWRP later to my rooted phone
Assuming the above are true (if not please tell me!!) my question is this:
What on earth is oem unlock/bootloader unlock? In my reading I've come across people talking about this and it wiping the phone. I can't find an easy answer online. If I root +/- do CWM/TWRP will that automatically do OEM unlock or are they different things? Is bootloader unlock a different thing too? I'm confused! Will I need to root AND custom recovery AND oem unlock AND unlock bootloader?
Thanks in advance!!!

Some devices come with a locked bootloader, where you may be able to root the device via an exploit, but you can't change lower level software (ie kernel and/or recovery)... unless there is an unlock method for the bootloader.
The devices that do have a locked bootloader can be locked by the manufacturer, or by the carrier. That's the difference between the two. Either way the bootloader is still locked, only difference is who called for the locking.
For example, note 4 on tmobile does not have a locked bootloader, however, note 4 on at&t does. That decision was made by at&t, not Samsung. As far as I know, the at&t variant does not have a method for unlocking the bootloader yet so there's not much development for the device.
Compare to nexus devices, where Google automatically has the manufacturer lock the bootloader, but it being a development device, it's the easiest bootloader to unlock. It's literally a one line command in adb. HTC devices are locked but you can get an HTC dev code to unlock it from HTC.
I hope that makes sense. The best way to determine if your device has a locked bootloader is to visit the development forum or the general/Q&A forums for your device. If you have a locked bootloader and there is an unlock method, you only have to do it once (until you update or relock your bootloader). Some locked devices never get an unlock method. It designed to maintain the security and integrity of the device, but it also prevents user tampering.

Thank you for your thorough reply absinthesummer, very helpful.
However I'm still a little confused. My reading suggests to me that T-Mobile (910T) is *rootable* and the AT&T version (910S?) is not *rootable* but I'm in the UK and don't use these providers I use EE. And so I have the international variant of the Note 4 which is the 910F. I don't see a subforum or help for the UK EE version of the note 4 but as it's the 910F I assume that's the one I need to search for and not worry that EE will have put their own lock onto the 910F??
Now, because this happens to coincide with what you are saying has a locked bootloader or not, am I to assume that whether or not something is rootable is the same as whether or not it has an unlockable bootloader? i.e. is something only rootable or not because its bootloader is unlockable or not? If so therefore am I correct to assume that as the 910F which I have is rootable that it is also bootloadunlockable? And furthermore am I correct to assume that the very process of rooting itself unlocks the bootloader? Or perhaps in the case of the 910F it doesn't need to be so is even easier than Nexus devices? i.e. I just simply root and that in itself mean bootloader is already unlocked (and I am assuming that oem unlock is the same thing?)
I'm getting myself in a muddle I think!

Hehe it's totally cool, and yes your carrier could put a lock on it but that's incredibly rare in Europe due to frequent traveling between countries and the need to change Sims and carriers often... or at least that's what I've been told. The US carriers who lock their bootloaders are typically GSM carriers who do not expect you to need to root/carrier unlock/whatever. It's a control thing imo.
Anyway, your note 4 does not have a locked bootloader. If you check the development forum for your device you will see plenty of roms and guides and directions for rooting. That's usually a good indication that a device is unlocked (and those anticipating the release of new devices tend to get lock information prior to release, so they know which device they intend to buy).
Anyway, since you don't have a locked bootloader I wouldn't worry about it... that reminds me of a device I had for about a week, the LG L9. It had an oem bootloader lock but the international variant did not. We could root it & use a specially designed recovery with the bootloader locked but we couldn't flash a custom kernel (with a custom rom). They figured out that we could flash the international firmware and unlock that way, but it would make our display backwards (mirrored) and while that could be fixed, we would never be able to revert the boot screen. Now that's way too much trouble to go through just to unlock a bootloader and I did end up returning it and getting an s3 instead.
Bootloader locks are no fun, but they are not often placed on international devices for various reasons, so really I wouldn't worry about it too much.
If you get a device like a Google nexus, or an HTC that has a known locked bootloader, the bootloader and unlock method will be specifically mentioned in the routing guide. I hope that helps.
One more thing: rootability and locked bootloaders are not mutually exclusive, sometimes you can root devices with locked bootloaders and sometimes people will come up with ways around them (ie note 3 has safe strap recovery that runs parallel to stock recovery) to be able to use custom roms. However, if no exploit is found and there is no workaround, development will stall until one or both of those things is found. You may be able to root a device with a locked BL, but you may not be able to flash custom roms/kernels without a workaround. What I meant though is if you see a popular device with very little development, that's probably due to a locked bootloader and not having found a way around it yet. Most guides will explicitly mention the BL though if it's something you need to do

Yet another thoroughly helpful and detailed reply. Thank you very much indeed. You're a star!

A Step Closer To Unlocking Bootloader H815 SEA.

autoprime> never knew it existed until u mentioned it 5 min ago
<Zenn> this is interesting will post on XDA
<autoprime> get on xda and figure it out with a few others
<autoprime> but even with device id .. ur not gonna get an unlock.bin from lg
this was found on accident lol anyway for those who is interested this is H815 SEA ASEALB, apparently there is a OEM Unlocked over in Developer Setting. but it is password protected.
Version as Followed.
Android 6.0
Build Number : MRA58K
Software Version v20a-SEA-xx
rebooting to bootloader states to unlock via OEM Lock.
picture are as followed.

maybe we can try cracking it with bruteforce?

Probably but why would they want to protect OEM Unlock for ? unless the site is capable of unlocking since the oem unlock is preventing us from getting device id. after all there was a internal testing done for sea related device till the loophole was discover, as much as I hope, either way I hope either lg release the official lock or one day an unofficial ones comes out. cant wait to test cm on this baby.
@xrad @autoprime @jcase @IllegalArgument

We have the same setting in LS991's developer's settings which you can toggle with just your lock screen password. There's no purpose for it because there's no bootloader unlock, sadly.

the internet has failed, request mod to close the thread.

All lg g4 devices have oem unlock

Us t-mobile giveway to developer

I am giving away a new S7edge to a developer of my choice to work on and create root/unlock for the snapdragon version.
If you feel you are competent enough to provide root for this device then send me a PM.
If you feel you know a dev that can do it if they had the device in hand then post their name here in this thread or send me a PM. In the end I choose who gets it based on their background. I will pay for shipping, etc for the developer of choice. All I ask is for you to work diligently on this device.
This device is the future of locked, unrootable devices. The sooner we get through this barrier the better for the sake of all future devices. This isn't the end, only the beginning.
There will be no developer bashing in this thread and will have this thread closed immediately if it happens.

Good offer! This giveaway plus the bounty would hopefully entice someone. It's a good chunk of $$$!! I really hope someone with enough time and smarts would find root. I can live with TW as long as it is rooted (I'm a rooted 930F user). See T-Mobile Galaxy S7 Edge and AT&T forums for the bounty threads. I think there is another thread on the Sprint S7 forum as well.
OP's giveaway is for an SM-G935T, Qualcomm SnapDragon SD 820 Galaxy S7 Edge. All US variants are the same (SM-G935T/A/P/V) . A root for SM-G935T should work on the regular US S7 as well (SM-G930T/A/P/V). It is bootloader-locked and it will remain so unless Samsung releases an unlock, but due to the way the BL was locked, it would be near impossible anyway. So, no custom ROM.
It may be rootable if a stable exploit can be found. Folks have been comparing the US SnapDragon to Chinese SnapDragon S7, but it is not comparable. Here is a good summary regarding the bootloader situation:
mathieulh said:
The CROM lock does not exist on non-Chinese bootloaders
Samsung's Chinese handsets bootloaders have in 3 types of bootloader locks, the carrier lock, the CROM lock (which is enabled if the Chinese bootloader does not find the "KIWIBIRD" string written in the STEADY partition), and the reactivation lock, they are not carrier locked.
U.S. variants only have the Carrier and reactivation locks, there is no CROM lock to unlock on these devices (or any international variants either), U.S. variants are however carrier locked, the lock is hardcoded in the bootloader code (there is just no execution path to load an unsigned kernel on the consumer carrier locked variant bootloaders, there is no "lock" Qfuse anymore, the bootloader itself just has no carrier unlocking/locking support, it is always locked by design) and the bootloader is tied to the device ID, for example SM-G935F (which is One Time Programmable) and will refuse to run on anything but the device id that is hardcoded within it, obviously the bootloader is signed so you can't modify it, there is also a revocation mechanism involving Qfuses to make sure you can't downgrade to a vulnerable version (should one exist).
There are presumably Engineering versions of the bootloader that allow running unsigned kernels but those have not been leaked and they probably won't run on devices for which the production mode Qfuse has been blown (the device is in Engineering mode when that Qfuse is not set).

How to Unlock Bootloader

Someone Plz Take Initiative To provide Guide on How to Unlock Bootloader
Roms. Have started coming out
I would nice if someone made this

Have you try it from, https://www.nokia.com/phones/en_int/bootloader/
I don't know if it's working,,, I'm not planning to unlocking bootloader yet.. since development of the device is not really good (yet).

Itz not working app crashing literally everytime

Screenshot

What happened in the process since you opened the webpage?
Is there any command? Is it requiring you to install an apps or something?
Is it "OEM Unlocking" menu on developer options turn to live so can be disabled or enabled?

They ask for email id and pass code
Pass code we get from the hmd boot loader app and app is crashing while asking to confirm bootloader unlock

Nokia doesn't allow to unlock our bootloader officially..
That's why app keeps crashes

https://www.techmesto.com/guide-unlock-bootloader-nokia-android-phones/
Check this link, Its paid but.

There should another way or something to bypass and.unlock
There is no point in having many good roms when u can't use it

Adding to this point, the HMD app pointed out will only work for Nokia 8:
https://www.androidpolice.com/2018/...-announces-bootloader-unlock-program-nokia-8/
Hopefully, they will open up the program for more devices.
Nokia had blocked the unlock process last August due to a security threat: https://www.xda-developers.com/augu...nes-blocks-the-only-bootloader-unlock-method/
There's already another thread on this forum which guides you to unlock the bootloader by first downgrading back to the firmware before this August update

It's a reliable service. This is the only way to unlock bootloader currently. I can recommend this..

My Nokia 6.1 plus stuck on androidone download mode
Please help me

How do the paid services generate the unlock codes with IMEI and Serial number?
Any luck with getting bootloader unlocked using their unlock keys, Any experiences with these?
Is it possible to unlock without using these 3rd party services, Are there any algorithms for this. Its been more than a year since its release and still no reliable method to unlock these phones after the security update.
Is it possible to unlock bootloader after downgrading to Oreo, does this require any unlock codes.
