Greetings to all fellow users and community,
I just bought an Spanish Retail version for Edge+, but I'm using it for Mexico carriers. The version I've bought is for TIM carrier. Would I brick my moto Edge+ if I manually flash Stock Firmware from Mexico (Open Version or Retail Version) ?
Any comments and advise is appreciated
Cheers!

Yes, you could brick it, if the bootloader is locked.

Thanks for so quick response, appreciate it. That wouldn't be problem since I already have bootloader unlocked for flashing. My concerns would be bricking the phone due to differences in basebands or vendor files, for example.

As long as it's the same model # it should work, you will see a warning when the device boots.

You can just flash the radio firmware, it is a little safer.
Flashing the Radio Firmware
it's a good idea to run
Code:
fastboot getvar all
before flashing anything and keep a copy of it, for reference later.

Hey it's me again,
What would be the difference between using lenovo's rescuing app against the manual procedure using fastboot?
I come from xiaomi, where to be able to replace partitions like Vendor, you should put the phone in EDL mode in order to be able to flash/replace those partitions...
Wonder if with moto edge+ there's some considerations in place...

The advantage of LMSA is automation and access.
LMSA can check the device, determine the correct firmware, and download that firmware from a Motorola Server.
All the other sources of firmware are 3rd party.
LMSA can use the included flashfile.xml that contains the recommended flash commands.
Flashing manually with fastboot.exe requires opening the flashfile.xml and figure out the correct commands.

There's been very little development using Moto EDL mode.
It's almost exclusively used with a blankflash to rescue the device.

Hello guys,
I tried to unlock my bootloader a few weeks ago and it was horrible, so i sent it to service and they sent me a brand new phone. But i want to unlock bootloader and i don't know what files use excatly on this model. Can you help me?
Sys. info : ver.: 45.31.20.MB860.Vodafone.en.EU
Android stock 2.3.4
build num.: 4.5.2A-74_OLE-31.20
root: yes
unlocked bootloader: no
What exactly is so confusing here?
Clearly you need to use the ihop version. The rest of the process is the same for every Atrix out there.

IHOP bootloader
Unlocking the bootloader doesn't always work (depends on the device and some other things), but I can't imagine a situation where a failed unlock would require taking the phone to the service center...
Ok, i'll try it tomorrow thanks....but when it fails ? ...last time it said me "failed to boot 2" ...
Did you actually read the whole procedure? Because it doesn't seem like you did.
Yes, I did....then i tried to search far on the google and i found that i am not alone with thi problem. Many people is saying, that is unable to unlock this bootloader...:/
http://mobility.forumsee.com/a/m/s/p12-9847-0229151--atrix-bootloader-unable-unlock.html
"Failed to boot" is a perfectly normal and expected part of the unlock process and everyone gets it. All you have to do is boot into fastboot mode and flash a custom recovery, then use that to flash a ROM. I don't know why you went to Google, literally all you need is here on XDA.
I used this guide to unlock 4 Atrix boot-loader so far including my own http://atrix4ghacks.com/atrix-4g-hacks/how-to-unlock-bootloader-and-install-permanent-recovery/
Ok, I will try it now ....
EDIT: it still gives me that OEM unlock is not implemented...
Either you didn't flash the IHOP SBF correctly, or you have one of those newer Atrixes that cannot be unlocked.

The only thing you can do is join the crowd of people who have the same problem which has yet to be solved. There is nothing you can do right now to unlock your device.
I know that pain.. I am an Atrix owner too, who owns a newer one..
I don't think that we will see them unlocked, because a lot of devs already moved on and there are now just a few Atrix owners..

And I flashed this firmware

After that the phone doesn't boot its dead

Can anyone have a solution to recover my phone

Same here, we need the LATEST rom firmware LPI23.29-17.5-7 released on 11/16. What happens is that when another gpt.bin is flashed on a bootloader locked model it messes everything up. The only way to save it I think is when a NEWER gpt.bin version of the correct model is flashed over so that the correct boot.img will take.

In this bootloader you can flash whatever even you flash the firmware of any other motorola model that's why its too dangerous
Actually those phone's have motorola factory firmware which is used only for checking the phone after manufacturing in factory like samsung combination files but for motorola its not available publicly
Only moto factory have those bootloaders and firmware

Hello everyone,
As you know there are people working on the laf exploit, well I found my way and now I'm helping out on the v30 end. Unfortunately, I have Verizon variant of the v30 when right now I need the the fully unlocked us998. Can I get somebody who would be willing to work with me who has that specific variant? Let me know if you'd be willing to help by commenting down below and I will contact you via xda messages to start. Thank you ahead of time for willingness to help! Hope to hear comments really quickly! Thank you
I have the US998 V30+
I just flashed it to the Verizon Oreo KDZ. Not sure if it is any different than yours now.
Let me know if I can help.
I guess it depends what you mean by "fully unlocked."

Hello there.
I am aware that - at the moment - the global version of this phone cannot be unlocked. I'd just like to know when - if ever - the bootloader will be able to be unlocked, and if I can still roll-back to earlier versions of Android with SP Flash Tools (I really don't like how restrictive Android 11 is. Shame on Google.).
Thanks.

Is there any one click rooting tools that work with Android 9 - 11? Preferably 10 - 11. I want to root my droid (I have an AT&T LG G8 Thinq) and I don't want to unlock my bootloader. Please don't say "C'mon dude just unlock your bootloader", I'm looking for an actual answer(s) here. Spyware or not. By one click root tool I mean something like a tool that you can press a or a few buttons and it roots your handset. Yes I'm aware many of great old ones are spyware.

It is possible to have LinageOS with a locked bootloader. You can relock it and revert back to stock recovery, so people can not flash anything to bypass your lock screen. This is very common for OnePlus devices. You can sell it and buy a OnePlus, throw your phone.

Only works with some OnePlus devices. You can sign your ROM with your self-signed certificate. You can modify your ROM to whatever you want(including root) then just sign it, flash it, and re-lock. The bootloader now checks your self-signed certificate.
I don't think your needs can be fulfilled with your current device, maybe you have to sell your device.

So basically with a OnePlus I could just flash whatever I want and relock as long as the ROM is flashed LAST?
Also what's so hard about getting a signature? Why can't someone just pull it from the existing stockROM and put it on a their own ROM, so they can relock an Xperia or LG or something with a custom ROM?

lol, impossible. If what you said is possible, then SSL will be a piece of * because everyone can pull the signature simply by visiting a site. You need to learn what is "private key" and "public key". You need a "private key" to sign a thing and that private key is secret.
OK, so the solution is... Break into LG headquarters and obtain the key signatures and spread'em all for the world to see!
The less exciting options include infiltration or bribery...
