Unlock Bootloader to Upgrade from Android 5.1.1 - Galaxy Note Pro 12.2 Q&A, Help & Troubleshooting

Was anyone had success unlocking the bootloader on the Samsung SM-P905V? I run an app for work on it and the latest release will only run on Android 8.0 or higher. Any assistance would be greatly appreciated.

I have the exact same model, but unfortunately, I have tried all sorts of methods but the bootloader is almost impossible to unlock on the P905V. So it is basically stuck on 5.1.1.

[Q] 9.30.1.XT926.VERIZON Bootloader

I purchased the phone brand new thinking it would come with the very first firmware so I wouldn't run into this issue.
Well. I'm scratching my head debating whether or not to send it back.
I have successfully obtained ROOT using Towel-Root. But I'd really like to unlock my boot-loader!!!!
I have Googled everything I could think of, watched NUMEROUS videos. But no one else is running 9.30.1.
I have read that if I take the OTA update to 184.x.x then I would be screwed with ROOT and boot-loader.
Am I missing something? Or is it not possible to unlock boot-loader on 9.30.1?
If it's not possible, is it possible to use fastboot to flash Cyanogenmod to my XT926 without custom recovery since I have obtained ROOT?
This really sucks. I just upgraded from an XT907 running 184.46.15 and was upset because I could not gain root.
Can I update to newer android OS and still obtain root on my XT926?
I've done it!
Download the 183.46.10 update.
Use RSDLite 6.1.4 to flash the update.
Towelroot to root.
Motopocalypse to unlock bootloader.
PROFIT.

[q] need root assistance

I have an Xperia Z3 D6603 running android lollipop 5.0.2 and it says in my service menu that im not allowed to unlock my bootloader. ive heard that its posssible to change this on multiple occasions and seen phones of the exact same model and firmware as mine that have unlocked their bootloaders and rooted their phones and i would like to do the same. i have tried different methods of unlocking from both official and unoffical sources, with no success. if anyone can please tell me how i might change the status or how i can unlock my bootloader and root (yes ive heard the risks a million times, no i dont really care about losing the drm keys that allow better lowlight conditions with the camera, and my phone actually has slowed slightly since the lollipop update) it would be much appreciated and of course if any additional info is needed, i will of course provide such as quickly as i am able to. thanks in advance and all input is appreciated.
you cant unlock the bootloader then, if you want root then you will need to downgrade to kk and root the device and install a pre-rooted lp rom

XT1033 Bootloader Unlock alternatives? CF-auto-root?

I have a XT1033 (16gb dual sim) and I am unable to unlock my bootloader through the motorola website. I get the "your device does not qualify" message. I've tried contacting Motorola through many venues and in many different times but they have not been able to solve my problem.
And please don't say it is because I'm not inputing the correct code in the website, the code is perfect, that is not the problem.
So I was wondering, are there any alternative ways to unlock my bootloader?
I stumbled upon CF-Auto-Root and it seems promising, but I am not sure wheter or not it is a good idea to use it given that I am on a newer Android version than what they have on their repository (autoroot.chainfire.eu) - the repository is on 4.4.3, my device is on 5.1.1.
Any help would be greatly appreciated!

Need help rootijg the GALAXY S7 SM-G930T T-Mobile Variant

Im new to thus ohone and how do i root this phone it's on Android 8.0.0 and idk how too root i tried cf-auto root but bootloader fails idk how to unlock bootloader
The snapdragon / US models (G930V/T/U/S/P) can't unlock their bootloader
The only method is using a leaked engineering bootloader that's unstable and limits charging to 80% then using flashfire, but I don't know where to get this BL from.

[S8+] Purchased a stock AT&T S8+ in a lot. It has latest bootloader and bad IMEI....

[S8+] Purchased a stock AT&T S8+ in a lot. It has latest bootloader and bad IMEI....
First off, I'm an engineering scientist with years of development experience developing both hardware and software for all sorts of phones and companies. So I feel I'm pretty familiar with Android and every conceivable (and off-the-wall) way to get this phone unlocked, rooted, and/or just flat out usable. And I have failed which is why I am finally giving this to the multiverse in hopes there is someone with some solution I have yet to attempt.
I have been searching and trying every possible option for a week and counting. I'm also aware of how close to impossible it is to work with locked Snapdragon CPUs. But not entirely impossible. There has to be a way of reviving this phone!
So I recently purchased a lot full of untested and "for parts" electronics. In there was an AT&T S8+ with a cracked screen. It was also stuck in a boot loop, so I can safely hazard a guess that someone tried to update the ROM, bricked it, and didn't realize they could reflash stock firmware and fix it. Well, upon further examination, I discovered they had attempted flashing a V7 bootloader. Yes, version 7. So that basically robbed me of any options I may have had, as well as all the bugs I could have used to root the device. All I could do was install Pie with a V7 bootloader. Voila! The phone boots up. But it gets better....
Now that the phone was working, I did some examining, one part of which was the IMEI as I wanted to unlock it if possible. I check the IMEI, and it is frakking blacklisted! So that blew ever being able to use this phone on a network. I even sat on hold for 46 minutes to speak with someone at AT&T to see if they could remove it off the blacklist. They promptly said "sure!", then transferred me to someone else to fix it and the guy said "no".. So it's stuck locked to AT&T, which sucks because I checked with several other networks who all said the phone could be used on their networks. But that's not an option if it is carrier locked and impossible to unlock. :silly:
Furthermore, OEM Unlock is 110% unavailable, and no bugs work or exist to force it to appear on Android 9 Pie like you can with 8 Oreo and 7 Nougat; and I tried for days. So the bootloader is permanently locked. If it wasn't, I could root the phone, fix the IMEI, unlock it, and get the phone functional again. Alas, I cannot, at least any time soon, if ever.
I've tried every possible thing out there to root this, unlock the bootloader, and/or try to roll back Pie to Oreo, Nougat, or some stock ROM with bugs that are still active. At the very least just to change the IMEI and get the phone working again. But there is no version of Oreo/Nougat that can be installed with a V7 bootloader.
Also, there is absolutely no Engineering Mode (NOT Developer Mode) available under this stock Android 9 Pie, either by code or by app/settings. Does anybody know of an exact Android 9 Pie stock ROM with an accessible no-root Engineering Mode?
And I've tried every way out there to force OEM Unlock to appear, but the bugs that work in Oreo and Nougat have all been patched and none of them work on Android 9 Pie. So I'm stuck with this ROM and bootloader
So I'm here today with these issues in hopes someone may have solutions for:
A way to force OEM Unlock to appear under Android 9 Pie (as no Oreo/Nougat hacks work under Pie)
A way to bypass KG state under stock Android 9 Pie (as no Oreo/Nougat hacks work under Pie)
A way to install Android 8 Oreo or Android 7 Nougat with a V7 bootloader
A stock ROM with Engineering Mode available
A way to change the IMEI without root
A way to modify the V7 stock ROM so it installs a Nougat/Oreo ROM instead of Pie
Another option to keep this phone from just being a fancy, pretty paperweight
Any solution we or I may discover, I will clean it up and make a guide to help others with these same issues as there is not much info yet V7 on bootloaders. So this is a group activity that could help many, many people; help me help us all!
Thank you all in advance for anything you can offer to help!

EDIT 1: I forgot to mention that the KG State is stuck on "Checking...." so I couldn't get "OEM Unlock" even by waiting
I used this video to figure out how to get the OEM Unlock option.
(input this after youtube url) watch?v=zhNhyT4F3e8&t=133s
Hopefully this helps.

Click to expand...
Click to collapse
There is no OEM unlock on us snap dragon devices. Locked boot loader. Closest you will get is the combination firmware. But the OEM unlock in that does not work trust me on this. The imei is cert coded to the hardware. And can't be discussed on xda how to change. It's possible. But not by just anyone. The combination files are nougat. But their not going to help you out in this situation
