How to fool Googles Security on a used bought Moto G?

Hi guys, i hope you can help me out here.
a Friend of mine is a taxi driver and had a guest who forgot his money and paid with his Moto G 2015 8GB.
As a friend of good deals, my friend now wants his father to use this Smartphone since it offers enough for his needs.
I already set it up from the scratch, but google now wants me to login with the first account data from the previous owner, which im afraid-, we wont be able to obtain any more.
Id install Cyanogenmod without Gapps to ignore the Google Questioning, but i need to check the "Oem bootloader unlock" option, which i cant, cause i cant setup the smartphone any more.
I hope anyone of you can help me? The Phone it not stolen, so as far as it is possible, please help me!

Goto stock recovery and using vol.down+power key u will be in fast boot mode using vol down chose recovery mode and press power key to enter into stock recovery. If u see a dead android just press power key first and holding it press vol. Up then just scroll down to factory data reset and now every g account will remove. Now set it up

A factory reset will probably not help. Moto G implements the new Factory Reset Protection feature which Google did introduce with Android 5.1. This check for the password of the last Google account registered on the device will survive a factory reset.
To my knowledge there is a way to circumvent the Factory Reset Protection on some Samsung devices due to a faulty implementation by Samsung (this was in the news a few days ago).
But this will probably not help with the Moto G.

Just reflash the stock firmware and you will be good I hope

You can't do anything with stock firmware, you can't unlock bootloader. The new system protection is exactly for that purpose. If your reflash the firmware via fastboot, at first boot prompts you to login with any google account used before in the phone.
The only way to revert the locked status is login with google asociated account and wipe from the settings menu once the phone has been unlocked.

i tried the stock firmware reflash as well.
you so are telling me there is no way to get a working firmware on this phone without going actualy in the developer options and activate bootloader thingie?
i mean google did a good job on that part. Still sucks though, but thanks for the answer

Yes, you have no option. To unlock bootloader you need to turn on the oem unlock permission in settings and actually you can't enter in that setting.

When you reflash the stock firmware via fastboot it clear all data & cache. When boots with clean system it prompts again to activate the phone.

For one side is nice to see that this works... Too bad for you... I guess you already googled it right?

Bricked my Mate 8 - Downgrading from B330 to B211

Failed attempt to downgrade from B330 to B211:
Model: L29C636B330
- Got to eRecovery, but wifi can't find anything
- put B330 on SD card dload but 3-button reset only bring me to a EMUI menu with Reboot, Wipe data and Wipe Cache options. Cache wipe could finish (seemingly), wipe data would quit midway, sometimes in a couple of seconds, sometime longer. EMUI logo turns to red exclamation mark
- fastboot works... however, phone is locked (I suppose that means bootloader locked?) therefore, fastboot flash is not working. adb push file - device not responding.
This phone is all stock with no prior rooting/bootloader unlock. Except for using FF to get to B330 - to be fair, B330 worked fine.
I did not bother to get the paid unlock code (should I?), as from I what I read, it probably won't oem unlock because I did not have the dev option enabled prior, and I can't seem to wipe the device either.
Pardon my repost while this thread is still fresh... https://forum.xda-developers.com/showthread.php?t=3563299 because I have not messed with 3rd party tools yet and I want to make sure people can respond to my case specifically. Though it is worth noting perhaps that this could be caused by B330?

No. Because DC-Unlock seems to assume access to phone and enable USB port for "manufacturer mode". My phone is in bricked as described in my original post. I guess my only options are to see if Huawei will give me the key still or RMA the sucker?

Since you are still in bootloader locked. You might try to ask huawei service center to make your phone functional again. That if you bought your phone at your region. Or else request bootloader code via huawei website.

Yes. Emailed them. Will have to wait for their reply... I dont know if I can still get the code from them because I cannot login for 14 days continuously. Will see what they say.

What code Read my original post. I had no intention to mess with custom OS so I never unlocked my bootloader. For the record, I used to build my own kernel and mess with custom OSs all year long, but as Android matures I don't see much of that need anymore.
You do have a point though, I trusted Huawei too much. Should have obtained the code ahead of time regardless.

Samsung S7 Custom binary blocked by FRP Lock

I got S7 SM-G930L with a port Rom from S8 (https://forum.xda-developers.com/s7-edge/development/rom-s8-port-s7-s7-edge-ambasadii-t3619548). When I power on the phone I get a message: Custom binary blocked by FRP Lock.
I would like to get rid of the FRP Lock without losing my data.
I saw a video https://www.youtube.com/watch?v=VdAhu45UPsU According to the comments 40% lost their data and 60% didn't.
Could you please advise how to make sure that my data won't be lost?

reflash the stock fw using odin

Not sure
I was said that because I'm using a port of S8 on S7, after I'll reflash stock ROM the data might be lost due to differences of memory formats.
Is it true?

Firstly I have a question regarding the OEM unlock as I just came out of the FRP Lock. Do I turn on OEM unlock or does it have to be turned off? Last time I had this FRP Lock was a year ago though did it again(the mistake with the OEM unlock) as I had forgotten it(Lots of grey hair)
Just don't know if it has to be on or off?
Secondly I have managed to come out of it(so far , hopefully) without wiping data with this guide

To unlock your device by frp lock you must flash the stock firmware when you are in bootloader mode you see custom binary blocked by frp,if you try to flash a random firmware(always of your device) the operation may not be a good end and device say an error with this:
Knumber) Snumber) Bnumber)
When you go to download the stock firmware you must see the "code" Of the firmware with write the same S or B number

It stops someone stealing your phone, wiping it, installing new firmware and using it as if it was new. If you know the gmail and password you put on the phone to access the play store then you just need to re-enter it after the phone restarts. FRP will only kick in if you have flashed new firmware to the phone.

I have a new firmware flashed on the phone.
And I'm using a new gmail with is, not some one July bro used on it.
What am I to do now? I have developer settings OEM unlock toggled on already.

I'm not sure what you mean. If you have a Google account on the phone that you know the email and password to, then just reboot the phone. FRP lock will only activate if you flash new firmware to the phone without removing the Google account first.
Your device should only have 1 Google account registered on the device which let's you access Play store etc. If there is more than one, you need to delete the ones you don't know the email and password to.

Okay...
Oh, okay, now I am getting the rationale.
Albeit, when I flashed in the new custom firmware, it started give me the undo changes by restarting your phone notification, like it did the first time ever that I got the lock. I didn't click it, activated an app that discarded the notification rather.
Now it makes me doubt if I had really removed my mail before flashing the phone.

hey
i have got the same problem. when i deleted xposed installer, my device rebooted. every time i try to turn it on, it says in top left corner 'custom binary blocked by frp lock'. i tried 3 diff rom to flash, no succes. i tried to acces twrp (my device is rooted) but again no succes. can you guys help me?
i have a G930F
thanks.

Yeah you've messed it up by not signing out of account before unistalling xposed. When you say 3 different rom's do you mean stock or custom?
Even in this state you should be able to flash a stock rom to the device with Odin and it will ask you to type the google email and password after boot.
Always turn off FRP lock before modifying the phone, it's a really annoying feature.

How To Guide [ROOT][GAPPS] Root and install GApps on stock Edge S/Chinese version

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.

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.

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.... :/

How to process system reset?

Hello, i ordered my pixel 4a from google shop without sim-card or carrier lock.
Now i want to reset my phone (download and flash firmware) but it dont work.
I tried it with "https://pixelrepair.withgoogle.com/" website but the problem is that it tells me always that the carrier i selected is not the same on my device!????
(selected "other" country and "other" carrier, but it doesnt matter if i select my country and one of the two aviable carriers, it gets me always the error massage)
What is the problem?
(bootloader is locked and i had an prepaid sim recently used in that phone)

It will get you to android 10. Then you can do the OTA to android 11.

I dont want to unlock my bootloader! (no offense)
On my old xperia device I was able with xperia companion to download and flash the firmware without problems.
Is unlocking the bl neccessary? hope not

You can unlock it, do the reset, then relock the bootloader - it's a simple switch in the developer options to lock/unlock the bootloader.
It's called "OEM Unlocking"- you can turn it on (unlock) or turn it off (lock bootloader)

I know, but I want just to reflash the original image, why it should be neccessary to unlock it for that?
I thought it just need to be unlocked for things like developer previews or custom roms not for official stock roms.

Part of flashing an image to a phone is to also flash the "boot" image, so the bootloader needs to be unlock.

Thats a good point, but i dont think that it is the problem.
The error massage says that the carrier of my device and the carrier i selected in "flash tool" is not the same, so i cant proceed.
I guess it would say something related to bootloader while i select my device if thats the problem.

Well, I have no idea about that https://pixelrepair.withgoogle.com website - it does not seem like an official google website because I doubt google would add "with" to it's domain name.
So, I would try downloading the official images using the link in the SECOND step of the guide I listed above - because that is an official image from google directly.

Flashing a factory image is only for when you've had an unlocked bootloader and been running custom ROMs or whatever.
You can factory reset the phone without flashing it.
Just go to settings -> system -> advanced -> reset.

It is an official google website as far I can tell, you can see it here google website but I was sceptical too at the beginning.

Sure but my question was about reflashing stock image (no offense).
I figured it out the problem was that I havent removed my google account before connecting to "pixelrepair".
After that I was able to select carrier and proceed.
But after that step it now shows "checking for problems" on repair software and on phone it says "waiting for command" until it quits after few minutes.
Anyone an idea why its not working?
(btw the flashtool and instruction never mention to unlock the bootloader so I guess its not neccessary)
