How to re-Lock the "Bootloader"/"Locking" the Phone back to stock? - Nextbit Robin

How to re-Lock the "Bootloader"/"Locking" the Phone back to stock?
Hello Nextbit Community!
I purchased a Nextbit Robin from a seller about a year ago and it shipped unlocked (every time you turn it on/restart it there's a black caution screen that states the device has been tampered with and it is unlocked), the phone boots up fine after the warning and I like the phone so far, bought it because i wanted a decently powerful phone for a budget that i can use on my carrier network Metro PCS (T-Mobile). Since I got the sim and activated it works fine but I want to use G Pay and other NFC services that require that phone wasn't "tampered" with. I'm a little confused on how to do this successfully and correctly. Is there a way to "re-lock/Lock the phone?. Does it interfere with my sim/data/cell service? will it wipe everything on the phone?
There is a lot of confusing info out there on how in great concise detail.
Basically I'm asking for some help on doing this because I really want enable G Pay, Can anyone give me me a super detailed and technical step-by-step on how to do this SAFETY without bricking my phone? Which "ADB" should I use? What do i need beside the stock image (N 7.1.1) and the USB driver? Any other programs? I'd really appreciate it thanks a bunch!

Do you still have this problem? Or you solved this?

New user, need help unlocking my s3 Rogers to Telus.

Hey guys I am new here. I tried unlocking my s3 via the UMTS/Network lock method but it wont work since my phone is on Android Version 4.3
How can I use Odin to unlock my s3 for use with Telus? I don't care about tripping knox as it's a hand me down and doubt It has any warranty or anything left.
You will have no choice but to unlock the phone via unlock code. Using Odin is not going to allow you to downgrade and unlock.

Gotcha, looks like I'm gonna have to pay someone for an unlock code. What are some good reputable places?
I would look for someone on ebay with a good price and good feedback. That's what I did for my Note 3 and Motorola.
I used the following thread a couple of years ago and have been switching between Rogers and Telus sims without any issues. Phone was originally Telus locked. This worked on 4.1.1, not sure if it will work on later versions of Android?
---------- Post added at 05:19 PM ---------- Previous post was at 05:13 PM ----------
PMd you the link. Let me know if it worked, I'm curious if it's still a valid method.
Using the 4.1.1 method on a phone with a 4.3 or newer bootloader may hard brick the phone.

Is anyone having trouble unlocking the bootloader on the european version? (LMG710EM)

hi, so I was trying to unlock the bootloader before attempting to use an AOSP pie rom using this guide on the official LG site http://developer.lge.com/resource/mobile/RetrieveBootloader.dev
Anyway when I come to step 9, I type "adb reboot bootloader" and the phone reboots in fastboot mode. Then when I type "fastboot oem device-id" the phone freezes and I have to press the power button to restart it, meanwhile in the powershell command page it says
Code:
C:\Users\chahi\AppData\Local\Android\Sdk\platform-tools>fastboot oem device-id
FAILED (Write to device failed (No such file or directory))
fastboot: error: Command failed
I checked my drivers and everything seems to work perfectly fine. I am at my fifth attempt and I'm beginning to feel pretty desperate. If anyone encountered the same problem or could help me solve this I will be very thankful !
Thanks in advance.
NB : I'm on windows 10 and my phone is running the korean pie rom.

I cannot 100% say what the cause is with certainty (I have the Sprint version and I absolutely hate this piece of trash) but others have reported similar issues from actually having a different variant that was cross-flashed to the EM model and sold as EM when it's really a Sprint version (for example). What happens when you enter your IMEI number in LG site, does it return the EM variant or something else? That's where I would start (unless you have already done this and confirmed it's EM). Non EM versions lack the full ADB support so we can't unlock the bootloader. This is the same point I lockup as well but mine was not intended to be unlocked.

Thank you for the quick response !
Yes I actually typed my IMEI in the LG site and it gave me a gray OK so I guess I truly have the EM version ? (knowing that only the EM is supported idk) Are there other methods to make sure I have the EM version for sure ? Also worth noting that I bought the phone new from North Africa so it must be the european version and not a carrier one.
Thank you !

Not that I'm aware of but if the LGdev site let you get the unlock code then I will assume it's real as they do validate it. Normally I would suggest to reach out to LG but that's a waste, they won't help. In fact they shutdown the dev recently because of unlock requests so they don't care about us so that won't help you. I'll do some research and see if there's any official way to help but hopefully others will chime in with the answers.

Good luck with LG, they most likely will do nothing to assist you. That's my biggest gripe with LG, they suck with customer care nor give 2 craps about us, the customers. My LGG7 sucks so bad, it's barely usable but they will not do anything to help me nor Sprint so I'm leaving both once my horrible lease is up. All I can say is to sign the bootloader petition and leave LG, it's the only way they will ever change and even then, they probably won't. They will soon be out of business just like Blackberry's downfall and for the same reasons. They don't listen to the customers and change, nor did RIM with activesync, now RIM is a mere fraction of what they used to be, LG mobile is next. I hear so many complaints about LG devices, not just LG mobile but the entire company. All the same type of complaints across all LG products, no customer support when the device stops working and they pass the buck every time, and locked bootloaders (for LG mobile).
There is no unofficial unlock yet, that's why I'm so unhappy with the piece of junk! If I could unlock and install my own flavor of AOSP then it would be an entirely different story and I would fix my own issues and have an awesome device. Instead the jackalope in charge of LG decided to keep the bootloaders locked with no support to unlock (except for EM) but even that barely works (your issue).
I don't know what else to say except LG SUCKS, LG is terrible. I so wish I hadn't let the Sprint rep bully me into this horrific device. I should have stood my ground and not accepted the deal which came with this expensive paperweight (LGG7).

SIM unlocked, yes, bootloader unlocked, no (on Sprint and everything other than the European model, no, EM model, yes), the rest of us, no, huge difference. I would pay a small fortune if bootloader unlocks were possible and why I bought the LG octoplus, still no option yet unfortunately.

Are you 100% sure this is not SIM unlocked using a modified octoplus (I have already gone down this path) so I bought my own octoplus. I am pretty sure all these "unlock" are merely SIM unlocks and not bootloader unlocks. I've investigated this pretty deep and it was only SIM unlocks not bootloader. As far as I'm aware, there is no hacks or mods to unlock the bootloaders for any LG G7 as of yet. eBay results are all SIM (which is simply using oct to apply the US-unkocked m ok model unlocking the SIM).
If you can find a REAL bootloader unlock method that works and unlocks my bootloader, I will PayPal you 20-30 bucks (I'm not joking). There is no method yet that anyone I know, knows of.

It's not sim unlock
It works by installing g710em bootloader and then flashing an unlock.bin .It's actual bootloader unlock. You can probably even do it yourself on a octopus box but I'm not sure what does it allow and not allow you to do.

If does exist, I can't find it on eBay or the internet, only SIM unlocks. I will keep checking but I don't see anything to unlock the G7 bootloaders.

Hey Piatch, i'm stuck on your same situation!
I have a new LMG710EM taken a month ago in a store, today with the Pie release (I'm in Italy) I found some time to unlock the bootloader, root, debrand (my G7 is TIM branded) and update to Pie.
I'm not new with LG, I come from G2, G5, G6 and now G7, never a problem (apart from the slowness in the updates I like them).
Well, just your situation, only the wording is a bit different, to me it says FAILED (Write to device failed (Too many links)) then the phone reboots and freezes in G7 logo and I have to press the power button to restart it, like yours.
I've tried everything, even reading online, different USB cables, different fastboot versions, but nothing worked.
Then I unbranded via lgup refurbish option to have a clean install and reinstalled all, thinking that maybe the new OS would solve but nothing, same message.
Can anyone help us?
It is the first time in several years that I have not found a solution.
Thank you in advance

Hi f0ster, I did not find any solution because I was lacking the time and tbh the skill to do it. I think we can't unlock the bootloader while under Pie ? Maybe if we roll back to Oreo, then we can unlock it and then update to Pie again ? I don't have the skills nor the confidence to safely flash Oreo on the G7 (I had bad experiences with bootlooping on the G3 and G4). Maybe you could try this way and see if it works out for you ?

Huge Problem, Locked Device and Stuck in Bootloader!!!!!

I have one Moto Z2 Force (XT1789-05), bought from coolicool.com, I didn't know device came Unlocked Bootloader, Device rom had problem with many apps, I googled and found one topic in XDA developer to Install Stock Rom, I downloaded and Installed India Rom, it's worked somehow fine, but still had problem, I downloaded Verizon Rom, Android 8, after Installed Android 8 Verizon Rom, Locked device bootloader immediately, now device stuck at Welcome Wizard in Android 8, after select language I got this message: (Please wait, this may take a few minutes) this is proof video (http://ahmn.co/Upload/IMG_0161.MOV), after this issue, device already locked, I can't unlock, because need to go to the Developer Option in Setting, I stucked in Welcome Wizard, there isn't any bypass, So, I start to search in Google, XDA-Forum, Android Central and more, I created many threads, many requests, no one can't help me, I tried to reach google developer support to the tell to me how can I bypass Android 8 Welcome Wizard, there is must be a way, but I can't find it, now I can access to Android Recovery and Bootloader
1. if you help me to FORCE UNLOCK device without need Developer Option in setting my problem will solve
2. If you help me to Bypass Android Welcome Wizard, access setting and enable OEM Unlock
3. If you help me to update the device from Android 8 to Android 9 Verizon ROM via ADB Sideload or Update from SD card in Recovery mode
4. If you have any idea to how can I fix it
Extra Information: I bought Belkin and Uni USB-C to Ethernet Adaptor to help me bypass Android 8 Welcome Wizard, I bought WSKY WIFI Adaptor because device Wifi can't find any network (I found QR setup by tap several times in Language Selection), after this section need to download google device policy apk, my device can't find any Wifi Network and my Ethernet Adaptor can't help me either, So, I just remained with my phone, and I can't do anything,
Please, someone, help me
My Device SKU: XT1789-05
These coolicool phones always come with the wrong firmware install, the simple solution to that is to flash the correct firmware which is plain old RETAIL. Solved. That's for anyone who might have or end up with one of these phones.
As for your phone and since you're in the situation you are I'd flash VZW pie. That isn't the correct firmware for your phone, but you've got a locked BL with VZW on it now and nothing is working. Since your ultimate goal is to flash pie anyways, that's what I'd do. Maybe that will clean up your system enough to enable oem unlock. If you can get your BL unlocked, then you're half way there. Surely by now you've realized that you haven't got many if any options.

Yes, I put my self in prison by locking bootloader, I already downloaded this firmware, but how can I update this firmware via ADB Sideload or Micro SD?

You shouldn't flash firmware from other variants like att, etc. However, if you're able to flash those firmwares and not get any permission denied errors then your bootloader is unlocked, which is good. If you have NOT flashed a pie firmware, good, do NOT do it until everything is up and running and you're sorted. If you have, then you'll need to use pie firmware to fix it since once you flash a pie modem there is no going back to an oreo modem.
Run this command from bootloader/fastboot mode and post back your output.

Bricked Note Pro 8 can't unlock bootloader nor install rom again

Hi everyone!,
Here's the situation:
RNote 8 Pro has european rom
Decide to flash the global one
Attempt to flash the global version (with "clean all and lock" setting)(which I totally forgot to change)
FlashTool says everything's ok
Device stuck in recovery menu with "This MIUI version can't be installed on this device"
Attempt to unlock phone
FlashTool locked device after attempting to write a rom
I did not activate nor the Unlock status nor usb debugging on phone before
So current state is that I can't install/modify bootloader since phone is locked
Can't unlock the phone since I can't acces to the OS
Any suggestion or what can I do?
yes i did the exact same error, this clean and lock is real crap thing !!!!!!
starting to think xiaomi phones were power users phones, but they are now as locked as apple phone
it was easy in DA/DL and SPFT to flash back and retrieve original state
but now it request an authorized account to flash this....i dont know why they do that, oh yes, for money.....
you buy a phone, but he isnt really your phone.....it always parts of xiaomi...what a shame
many bricked them with anti rollback protection
whats their problem....we do as we want
Start the phone in fastboot mode. Connect it to yr PC using your type c cable. Unlock it using Mi Unlock tool.
Could you fix it?

SM-A505U1

I've been told that this variant is "hard-locked" and it's impossible for it to be rooted without unlocking the bootloader. I was also told this with my sm-g900v and it finally got unlocked. So I was wondering if any developers have this phone and know how to switch "CSC" codes similar to how the "SM-G900V" was officially unlocked by switching it to a developer phone.
Can someone tell me if the magisk root method works on the A505U1 stock firmware? I don't want to risk bricking.
I have the same a50 Sm-A505u1, I dont know if they have oem unlock implemented into the developer options yet, hopefully within a few more updates they will add the option to unlock the bootloader.

Switching the CSC won't add the toggle because the model number is encrypted into the phone's processor.
Yeah you would probably have to do individual work on each locked variant depending on firmware. Even then it's a longshot to get any exploits to actually work, seeing how this phone doesn't have a removable battery I can only imagine the hard bricking risk. On my S5 I always backed up all my partitions on an SD card but I had root on that phone to do that.

I have the same a50 Sm-A505u1, I dont know if they have oem unlock implemented into the developer options yet, hopefully within a few more updates they will add the option to unlock the bootloader.

I know it's a little off topic but the system ui demo mode also doesn't work nor does the hidden menu. Hopefully a few updates will add more functionality to the phone.

I've been told that this variant is "hard-locked" and it's impossible for it to be rooted without unlocking the bootloader. I was also told this with my sm-g900v and it finally got unlocked. So I was wondering if any developers have this phone and know how to switch "CSC" codes similar to how the "SM-G900V" was officially unlocked by switching it to a developer phone.

I contacted samsung and they are saying that this phone cannot be oem unlocked, it sucks but I think after they are about to stop updating it they might add the toggle in the developer options.
Is the bootloader already unlocked since I bought the phone factory unlocked from Bestbuy. Could I root it now?
