[Q] Unlock bootloader without wipe. - Nexus 5 Q&A, Help & Troubleshooting

Hello xda friends.
How would you welcome the possibility to unlock the bootloader without wipe?
I have found two ways to do that a while ago, but first I want to ask you what do you feel about it?
I dont want to anybody to feel uncomfortable that even locked bootloader means no security to your userdata at all.
There is a reason why google implemented a full wipe after you do the fastboot oem unlock, to prevent thieves to get your data and personal infos by flashing a custom recovery then adb pulling the userdata partition.
So tell me your opinion. Depending on the feedback I decide to keep the secret or expose it to public.
You will need a windows pc to do it.

Release it. If the mods decide it's somehow illegal and or a serious security breach they'll let you know. It boils down to how you use the tool. Take a screwdriver. It's a perfectly legal thing to own and incredibly handy in it's intended use. Use that same screwdriver to break into some ones house and it's evidence.

Security through obscurity? No, thank you!
Expose it to us, please.

anyway if you can flash twrp with boarddiag tool when bootloader is still locked, then bootloder lock is nothing

I don't think you can flash boot partition with images without moto's signature.
How about use `dd` command to write modified raw partition?
I'm amazing it is likely on PC we have BIOS, boot loader and so on, BIOS can write via flash program & boot loader can write directly to boot partition or modify boot sector if you have physical access or root permission through remotely, is it right? please correct me if I'm wrong.

Raw partition might be able to come to reality, but mz still need time to work on it.
It will be great if we can unlock it to get free world!
So, how hard to get it done? is there any block on the road or it is simple need more time to get it stable?

Crack bootloader? not possible. but it seems system's signature can be passed by dump a cg39.smg from the phone, that is means possibility, but needs to testing.
You meant dump then RE it to find any security exploit which can allow us to bypass signature check from bootloader?
BTW, how about progress of existing research about this?
I've just ask Google for this and get some interest articles:

Possible to relock bootloader after root?

Hi guys,
It might sound dumb but I was wondering if it was possible to relock the bootloader while keeping root.
In fact, I did not want to modify my Honor 8 that much too soon but I enjoy playing some games on my phone using a pad, I did not want to spend alot so I just went with a pad I already have, the DualShock 4. It works well except the button mapping in native Android games, that's why I have to root to use Sixaxis app to solve the issue.
So I may have to root my device soon but I don't plan any other modification to the system atm and I particularly hate the warning message when you boot (gosh, I hated it on my Moto G but it was easy to replace).
That leads me to the thread title: Is it possible to root and then get rid of the unlocking message (relock the bootloader or anything else would be okayish)?
I just want to get root access on the phone for my gamepad issue and eventually setup some typical things such as a real adblocking solution (DNS66 is not bad but hosts file is still the way to go imo) and maybe Xposed.
Is there a way to reduce the modification on the phone? (Thus the idea of relocking it, I was thinking that maybe, once relocked it won't show the message. But maybe relocking just wipe the phone again? (as unlocking it does))
Thank you guys
thats possible to relock bootloader .but if u used flash custom recovery and SuperSu.zip to root your phone , after rooted device , please reflash stock recovery vi fastboot and relock your bootloader
I don't think it's possible to relock the bootloader and keep your device rooted.

It was possible with the Nexus 5 and a few other phones to root it and then relock it. Obviously the only way to know if that's the case on this phone is to try it. But you just have to make sure that the stock recovery is there instead of twrp before relocking.
One brave soul needs to try it though. [emoji4]

Well, I'll wait until someone who has a rooted device give it a try.
That screen would really annoy me... I always thought it was dumb to put that kind of screen... Damn, no need to remind us that it is unlocked if WE DID IT OURSELVES.

Response from Nokia on unlocking bootloader

I can't say I am surprised, but I thought I'd ask and see what they say. Here's an email and the response I received.
Me:
Hello, Before I order the 8, I'd like to know if you provide the means / process to unlock the bootloader for your devices. I typically run stock Android, which I know you provide, but occasionally like to run custom ROM's as well. An unlocked bootloader will allow flexibility, and providing the ability to unlock will gain you a following in the modding community. Thanks!
Nokia:
Regarding your inquiry about the bootloader unlock for the Nokia 8, please be informed that we may not provide this information.
Additionally, please note that unlocking the bootloader for the device will void the warranty and we therefore do not recommend it.
If you have any further questions, please do not hesitate to contact us again.
Best regards,
Nokia Mobile Care team
Now, I am really having a hard time coming up with a NEED for the bootloader to be unlocked... unless I need it to flash another region to add bands that aren't available on my device... maybe?

I wouldn't jump ship yet. Fact is, it still may be very easy to unlock the bootloader and gain root, as the device is runing bone stock Android. Frankly, there is not much left that I need root for.
For me, however, the 8 presents a specific problem. I live in the US, and the bands that are listed as supported are missing some LTE bands I really need (12 specifically). I am aware that there are ways to enable available bands for some devices, but I think you NEED an unlocked bl to get that done.
Thats likely a deal breaker for me. :crying:

Just taught to have a little chat with support too...
Maybe there's still a way to flash TWRP without unlocking the bootloader. They did it for example on the Nokia 6 by booting into what they call 9008 port mode (EDL in other words) and flashed the recovery with a tool named MiFlash in that mode. (Link to Nokia 6 thread)

Hi all,
i found an option in Developer Options -> OEM unlocking ->allow the bootloader to be unlocked.
To get developer options tap 8 times "Build number" in About Phone section of settings.
I hope this is the right way for unlocking bootloader.

We already know that. Enabling that setting doesn't do anything.
anyone tried unlocking bootloader via fastboot?
before i get flamed for being a noob, yes i know you need to enter a code or something to unlock bootloaders unlike pixel/google phones.
no harm trying right?
Hmm. I know some devices in my past have not required an unlocked bootloader to allow root, but I'm not savvy enougb to figure out if its possible on this device.
And rooting will NOT void warranty in EU.

I could only get the 8 into Download mode and could not install it as a FastBoot device.
Sure sucks that they seemingly won't allow this. I was interested in a Nokia phone as well. HMD have even said they want their phones to be like the new Nexus. They really need to support the custom ROM community if so!
Ok so, I can get the device to boot into bootloader(download mode) and somekind of a recovery, trough ADB in windows.
But no luck on "fastboot oem unlock" command. --FAILED <remote : flashing unlock is not allowed

Hi Daniel,
Does unlocking bootloader violates the guarantee/warranty?
I just purchased Nokia 8 5 days ago.

If you are in the EU, no unlocking the bootloader does not void your warranty. It's protect under EU laws. Someone mentioned that in earlier posts. Unless you are in asia or some other parts of the world where they screw consumers in favor of big businesses.
and if you had read through, there is currently no way to unlock the bootloader on the nokia 8. If there was a way and devs are willing to move over to this beautiful device, i'd get it in a heartbeat.

I was watching how to compile roms... But we will need a device source tree for compiling roms
Before that we neet to unlock bootloader
Can anyone try this command in fastboot mode and confirm if bootloader unlocks?
fastboot oem unlock
Make sure u have backed up your data because it will wipe data
I have my warranty for 6 months left? so can anyone without warranty test it out?
I will start development on it after i am confident enough on compiling roms and i get my new laptop?

Yep, I'm sure someone could test it for you......that someone is YOU.
If you want it tested, test it yourself. You said your device is under warranty, that means if you brick it, you can get it replaced. If someone that does NOT have warranty bricks their device testing this for you, they will be stuck with a dead device and no way to get it replaced, whereas, YOU CAN IF IT GOES WRONG.
You're asking others to risk their device for your own convenience to protect your own device. That is is being spoiled, rude and inconsiderate.

Be sensible? I was being more sensible than you understand due to your un-awareness to certain things about android devices. You've unlocked the bootloader and used ROMs on 3-4 devices in the past 5 years, great, that gives you experience with the devices that you own. That doesn't mean much when it comes to other devices, though.
It wasn't so much a matter of whether it was a potential brick or not, it was the fact that you ask someone else to test instead of doing it yourself. Generally, using oem unlock command does not brick a device....but, you aren't exactly right. Running the oem unlock command CAN and HAS bricked devices, they are device specific scenarios though. I have an RCA tablet that is unrecoverable due to using fastboot to unlock bootloader and that was on 4.4, long before all the extra security measures implemented by manufacturers and carriers today ever came along. Bootloader unlocking these days can be much more tricky than it was on that old device. So, as you said, do your research. I wouldn't have said anything if I didn't already know.
Also, you are aware that even if you tried the command and it unlocked your bootloader, you could easily relock the bootloader, which wouldn't void your warranty unless the manufacturer/carrier was standing right there looking over your shoulder when you unlocked the bootloader?

My point was to be careful what you post when it comes to unlocking bootloader these days. Bootloader unlocking gets more tricky by the day with all the coding and security measures used by manufacturers and carriers as time goes on. They are getting better at creating roadblocks for people like us. As these measures evolve, more and more users are breaking devices due to encountering security measures on their device that they were unaware of.

I'm not sure there can even be such a thing as generic TWRP due to the way it has to be built specific to the hardware in the device.

Typically, a locked bootloader won't allow this to work, the locked bootloader will see that the TWRP.img is not your stock recovery and won't allow it to boot.

Question Re-lock bootloader after root?

Hi folks,
I've managed to stumble my way through using pixel flasher to update my P7Pro to the latest fw with root. Only need root so I can record calls, should I lock the bootloader now I'm done?
Also how do I update in future please without having to wipe, use pixel flasher and patch as I've just done?
I like to think I'm quite tech savvy but the guides for the P7Pro have gone over my head :/

Not unless you want to brick your device. You need to be completely stock before relocking your bootloader (unless using avbroot, but you should have a deep understanding about how it works beforehand).

And you can't flash a factory image to fix a phone on your own when it's soft bricked. It might have to go to a shop for repairs.

AFAIK, relocking the bootloader requires wiping the device -- much like unlocking does -- and if you're unwilling to set everything (including anything on your /sdcard internal storage, not to mention all apps and their settings & system settings) back up from scratch (as any good complete backups require root access), this might not be what you wish to do.
And, if you had managed to successfully relock the bootloader, you could simply run the in-system update (OTA) that would update without wiping -- or even manually applying OTA from the recovery.
But there are hardly any benefits in re-locking the bootloader (after unlocking it) -- even if one was to a paranoid degree of security; which is the only major reason to (I can point you to the discussions that had taken place on it here, if you wish). If you don't want to run into any issues, you could simply run the stock ROM without root and be hardly impacted by it; with the added benefit of having the option to advanced recovery options and/or rooting options open to you in the future if need be...

never ever lock bootloader on google devices. fastboot only works on unlocked bootloader and there is no alternative to fastboot.

*it just occurs to me you meant to never lock bootloader because it limits options; not the risk of hard-bricking the device -- in which I wrote the following with that assumption. I'll leave the following comment as it is still sound advice, but I apologize in advanced that it doesn't quite relate to what you meant...
I mean, I feel doing Google's official Android Flash Tool is a safe enough method; it wouldn't do well if Google's own tool bricked their devices using their tool...at the very least the tool ensures that the stock factory firmware flashed matches the bootloader version and automates the fastboot commands so when re-locking the bootloader, it has the least potential to brick the device...
Exactly. there is no official flash tool from google, that's why I personally won't recommend to keep bootloader locked. If it's bricked with no working recovery mode, not even repair shop can fix it. all you can do is RMA to google get new device. no edl mode or anything else will help, fastboot is the official flashing method.
If you're referring to the "Android Flash Tool" that's no flash tool at all. I haven't tested it, but to me it looks like a WebUSB browser plugin. Reading the requirements it works with adb commands, usb-debugging and fully booted android is required. Therefore cannot unbrick devices.
Doesn't unlocking the bootloader break saftynet so then you have to root to use gpay?

I'll just chime in here because I have recently unlocked my bootloader but I haven't been able to root it yet and I haven't had any issues with safety net.

Interesting, I thought unlocking would break it. I'll have to unlock then for the extra safty!

That's of course another aspect. Good point. If you rely on SafetyNet or it's successor Play integrity, do not unlock bootloader. AFAIR the latter one can't be cheated.

There are some benefits like some banking apps, streaming apps and games beginning to work. So it really depends on what is important for the user. I don't like flashing random mods to make apps work on rooted/ bootloader unlocked devices, primarily banking apps.
