How do i unlock the bootloader on the G9550? (Snapdragon Variant, HongKong Edition with 6gb RAM./128GB Rom)
I tried flashing a custom recovery directly but i got an error saying not allowed etc.
There is no "OEM Unlock" option in dev settings.

Doesn't matter, still a snapdragon.
Unlock it using CROM

To unlock S8+ SM-G9550 bootloader use CROM service
Step 1: Download into your phone CROM.apk [message me for link, I'm new member and can't post URLs...]
Step 2: Install it by accepting from unknown sources
Step 3: Hit unlock and you're DONE!!!

What is this "crom.apk" and if all of the devs here couldn't find a way to unlock the bootloader for the snapdragon variant of our phone why would this work? Seems a little fishy to me.
I am not going to be the first to try it and brick my phone. If others try it and it works then I might try it.
Not calling you a liar, I just know that the devs here worked long and hard and didn't find a way to unlock this bootloader so I am not putting much faith into an .apk file. Sorry.

Well I actually found the CROM solution inside this site look for [[RECOVERY][OFFICIAL] TWRP for Galaxy S8 and S8+ (Snapdragon)] on the #3 posted by Jesec with link I run it on my SM-G9550 and unlock bootloader easily now my real challenge is to successfully root my phone which I believe is the path you're heading too, so far I was able to flash TWRP + dm-verity and force encryption disabler.zip + Magisk and been able to almost fully root it and I'm saying that due that if I activate Google account and shutdown/restart the phone it then get stuck at the Boot screen with a FRP locked message...

So you are saying after you run the crom on the next reboot it gets stuck, or only after you login to your Google account? If it gets locked/stuck at the boot screen then your phone is unusable. I am not trying to be a jerk or be difficult, and I hope you figure this out, but until it is fully usable I am not going to try it. Are you using the S8 or S8 plus?
Good luck figuring it all out.
Well, so I guess I should be more active in the site.
There are two firmwares for the G9550 the Hong Kong and the China, one has the bootlader unlocked and the other doesn't, you just have to install the one that is unlocked in your phone through odin. After that you can install magisk for root. I haven't done the process in Oreo, just Nougat, but I have a rooted S8+ g9550 doing this. Today I might try it in Oreo

I've been searching for a method to root a G9550 (the one I have is from China) for a VERY long time now and I still have practically no idea about anything. All of the Samsung phones I ever had were International models.
EDIT: Yes, I realise that Snapdragons cannot be unlocked, but for some reason I'm still trying to do the impossible. I guess I am not rooting the phone lol ¯\_(ツ)_/¯
I have been root and flash kernel my pixel 3 before, but I want use google pay, so I flash factory img to my pixel 3.
But i use google pay it is still doesn't working. Is cause i root before?
Have you re-locked the bootloader? An unlocked bootloader will cause Google Pay to not work on stock firmware.

Is it a good practice to relock the bootloader after root? I though it will reenable signature checks and brick the phone?

If you flashed the factory image you're stock and not rooted, right? But yes you shouldn't lock the bootloader again after modifications. You can relock it after flashing factory image from google though if you fon't flash anything else and don't modify it. That's also the only way to get google pay to work without root and Magisk hide.
Also, as long as you don't untick "enable oem unlocking" in developper settings, you can still unlock if it bricks, as long as you have fastboot access. So if you happened to brick by relocking, just unlocking again (and flashing if needed) would solve it anyway.

Thanks man, I'm thinking i have to re lock my phone now, or just wait new magisk can hide google pay.
Awesome how google sells a phone that is unlockable and easily rootable, but then blocks a service to the device. Luckily, where I am google pay is not an option, but I sympathize with you all.

There is a ton of information on the Magisk page about running Google Pay on an unlocked/rooted device. I use it on both a Pixel 3 and Pixel 3 XL. Locking your bootloader is not necessary right now.
https://forum.xda-developers.com/apps/magisk/magisk-google-pay-gms-17-1-22-pie-t3929950
this works.
Followed instructions and edited db and rebooted. Works great in Android 10 on Pixel 3. Thanks for this. I was wondering why wouldn't work on my new phone. So dumb to lock this down.
So you got the Edge S and want GApps? Basically you unlock your bootloader, root with Magisk, then install MagiskGApps.
DISCLAIMER: UNLOCKING YOUR BOOTLOADER MAY VOID YOUR WARRANTY, AND DOING ALL THESE THINGS IN THIS GUIDE MAY RESULT IN DAMAGE/BRICKING YOUR PHONE. I AM NOT RESPONSIBLE FOR ANYTHING YOU DO TO YOUR PHONE. PROCEED AT YOUR OWN RISK.
1. Unlock the bootloader: that should be doable with their global bootloader unlock website here.
2. Download Lenovo Motoroa Smart Assistant (Rescue and Smart Assistant), and follow its instructions to "rescue" your device. It will lead you to boot into bootloader mode and download the firmware. Find the firmware file via the LMSA's downloads (should have a "show folder" button). You'll need the boot.img file for Magisk.
3. Download Magisk, then follow its instructions. You'll have to copy the boot.img to your device, then use Magisk to patch the boot file, then copy the modified one to your PC.
4. You'll need fastboot. If you don't have it already, you can download the Android SDK platform tools here. Then go into the folder, Shift+Right Click the folder, then "Open Command Prompt" or "Open PowerShell," you should have something close to one of those two. Copy your Magisk modified .img file to that folder, then you'll want to input:
fastboot flash boot [modified .img file]
Once that completes, you should see in large text, "Start" on your phone next to the power button. Press the power button, and it should boot, and you should have root now.
5. Download MagiskGApps to your phone, open Magisk on your phone, click the button that looks like a puzzle piece at the bottom of the screen, "Modules." Click "Install from storage," locate the MagiskGApps file, and install it. After that it will ask you to restart your phone, do that, then you'll just have to be patient as it takes time once its restarted to load everything. You also may need to update some or all of the apps, then you should be able to use the notification to finish setting up the phone with Google Setup.
Thanks to Motorola for making it easy to unlock their bootloaders
Thanks to the whole Magisk team for making an easy, awesome root (and more!)
Thanks to Wacko1805 (and team?) for making MagiskGApps. This is really awesome.
unlock the BL and get root is will make some apps fingerprint and face ID fail?

Magisk has a "Magisk Hide" which will allow it to pass SafetyNet, and most things which check on device security will think the device is secure. But unlocking BL and rooting does make the device less secure, and therefore incurs its own risks apart from bricking or damaging the device.

Google Pay works. But according to the Motorola website you should be able to relock the bootloader if yours doesn't work. But there's never any guarantee. If you need your device secure, recommend don't unlock bl or root, or wait to see if there's a root option without bootloader unlock that can be easily undone.

I saw that someone’s edge s had unlocked the BL and Flash G100 firmware and everything worked normally, and then tried to lock the BL again, but it was unsuccessful and the system could not start. The flashing tool does not recognize the machine.

That's not good. Hopefully they can restore it back somehow. With this guide to unlock and flash gapps why would you need to flash G100 though? This seems to be itright now without one of rom developer's releases to get root & apps. For me this is all i would look for. Titanium backup on it and restore.. done until PE rom comes out.

I would think yes, if you flash different firmware, locking the BL would likely cause problems. It's very difficult to do anything w/o unlocked bootloader, except sometimes rooting is doable. That's pretty much the behavior I expect. If they come to this subforum, we might be able to help.

thank you. They did not ask for help. It seems that the lock BL is a self-verification switch, and then performs a verification system integrity.

I'm curious,If you unlock and flash other firmware and then flash back to the original firmware, can it be locked again?
Mine doesn't let me unlock its BL. I've got unlock code from moto and did a factory reset with SIM card in slot 1. After enabling developer mode and debugging the switch still is greyed out. So no chance to unlock it.
Has anyone got an idea what to try now?
Moto support answered yesterday to my request but also no solution since I told them that it doesn't work
Device is not branded. I got it from Amazon so no provider branding.
If this won't be able to be unlocked and rooted I'll have to return it and switch to a Google Pixel.

I had the same issue, you need to factory reset WITH your sim card in the phone, this will let you open the OEM unlock slide thing in the dev mode.
Then once its done you can fastboot and unlock the bootloader.
I did so, maybe I explained not so well. SIM was inserted and then I did factory reset by starting it from settings. After restart it's still the same - switch / unlock slider greyed out.

On my OG Pixel XL, I had to wait 7 days for the slider to become normal. By the time I got around to do it on the Edge S it was about the same time.... could be related
Now as you said that I remember that thingy with another device. Maybe a Xiaomi I think... With that I had to wait several days until the unlock code was delivered.
But there was a message, too, when trying to get it sooner, which said you needed to wait some more time.
Not sure if it's the the same for Moto devices? Then again, when thinking that you experienced the same with a Pixel, too...
Did anyone else make such an experience with his/her g100?

Make sure your on the latest OTA, Lenovo made a mistake on previous versions with the OEM Unlocking function not being enabled. They fixed it in latest ota.
RSA tool said the file I uploaded yesterday is the latest one available (and it's exactly the same as the installed version).
The device was released just a few days ago in Europe. Perhaps they fixed the unlock switch in other regions and still need to fix it in Europe..
Will wait until weekend if they come up with a solution. If not I'm afraid I have to return the device as I need it personally AND professionally, too - I'm field agent, so.... :/

The poor guy whose phone turned bricks went to the after-sales department of moto, and the answer was that he needed to replace the phone motherboard. .

I would assume so, but I don't really know why anyone would want to relock.
Just to preface, I'm not a total noob when it comes to android, but I'm definitely not savvy or knowledgeable in any way either.
I purchased a Motorola p50 a while ago from a seller on Aliexpress, and when booting the phone I get a message saying that the bootloader is unlocked. Going into the developer settings shows the OEM unlock option is in the off position, greyed out and with a message saying that the bootloader is already unlocked. However, booting into fastboot and running 'fastboot oem lock' gives me an error message telling me to enable unlocking in the developer options... which I can't do, because it's greyed out. Running 'fastboot oem unlock' tells me that the bootloader is already unlocked. From what I can tell the phone is running the stock android 10 motorola ROM, and I would like to lock the bootloader so that I can use google pay, as the phone supports NFC.
According to settings, the model is "motorola one vision", the hardware version is PVT, the SKU is XT1970-5 and the software channel is 'retcn'
Any help on how I can lock the bootloader, or even just get google pay working would be greatly appreciated.
There exists many threads on xda about this issue and it all boils down to this: your Bootloader thinks you're running modified software, hence locking it will hard brick your device (at least there is a possibility). According to the above linked thread, here's what you can do to troubleshoot this (in order of what could work):
Factory reset your device from Settings. (Relocking will erase your data anyways, Backup is advised)
Flash The Stock Firmware and attempt the lock process again.
Flash Magisk and enable Magisk Hide (this one is dangerous, since a modified boot.img while relocking can hard brick your device as well, do it at your own risk!!!)
Pass Safetynet check by flashing latest Magisk canary, enabling Magisk Hide and flashing this Universal Safetynet fix.
Step 4 is what I would do if I were you, however, advising people on the internet to root in order to solve this problem is not very wise, hence it being the last step.
Alright, I might give the last one a go since I don't know what the stock firmware for the phone is supposed to be. Thanks a lot for your help
Update: after attempting to install magisk with little success, I eventually found a single russian article that solved the issues I was having with magisk. I installed that plugin you linked, and success! Google pay now works without issue. Your help is greatly appreciated
