Just been unlocking the wife's moto g3, and came across this thread for getting rid of the unlock splash warning, and wondered if this was in any way relevant or a good starting point to do similar on the honor 8, by someone a little more technically capable than me...

Hi, the unlocked bootloader warning is located inside the fastboot partition, since there's so little documentation about it I wouldn't risk modifying it. (even if you wanted to, fastboot.img is 'obfuscated')

So, my understanding is this. If we unlock the bootloader so as to gain root access then the Xoom states to us that we will lose our warranty. That bites, but is expected. But if we decide to re lock the bootloader, it is my understanding that it, being the warranty is still void.
My first question is this. How will motorola know that we had unlocked the bootloader after re locking it? Is there a virtual trip in the system that creates a file that makes the statment that the unit had been unlocked? If so can we figure out where that file is located?
Now I could see a problem in finding the file in question if it does exist. But we would have to have a bootloader that is backed up from a Xoom that has never been unlocked. To compare the files. And that is assuming that that file resides in the the unlocked bootloader and not somewhere els on the system.
So, how can we backup the factory bootloader before unlocking it? Also, how do we make a backup image of the entire factory OS before root access is granted?
The reason I ask is because the steps and the image that is provided by Motorola for the OS may be tainted in some way also, so as to let them know that it is not the real original OEM installed OS.
Also, I have done a search, and came up with noquestions or answers to any of these questions. If the questions and answers are out there. I do apologize for asking again.
I doubt if they can tell the difference once it it relocked. You should replace the boot.img with the locked factory default file as well as the other original images (System) which is only available for the 3G model. Once you root the boot.img is replaced with a modified version which can easily be found out. Owners of the Wifi only Xoom will have to wait.
Hello,
I have this old motorola razr xt910 that still works just fine. LineageOS now has a rom for it so of cause I want to see if it's better then the older cyanogenmod. But back in the days of the razr, we ran safestrap because the bootloader was locked and motorola didn't release an unlock for my region or not at all. Lineage wiki page states to unlock the razr by official means or a third party. This got my thinking, if the bootloader is encrypted with an unknown key, how can third party software unlock it? There is no way I believe a simple local laptop can brute force it, so what else can such software do? So from a PC point of view, I would simply delete the partition and make a new. Now I know very little about android, so this might be blatantly obvious to others but why not just delete the bootloader partition and flash the one we want?
Thanks
No one has any answers or comments?
That sounds kind of simalar to the question I was asking basiccly there are locks in place that will brick a device if you replace bootloader files because of crc checks elsewhere.
So i was given this phone, well i bought it broken for cheap and managed to fix it, im quite versed in htc/sony/samsung/LG procedures and this was my 1st moto device, i managed to load latest 5.1 image via mfastboot commands, and i found that i need to unlock the bootloader to flash twrp, when i go to bootloader it says device is LOCKED status code 0, does this mean its already unlocked? i went to moto site and did the whole get oem unlock procedure pasted it into the site and it said it cant be unlocked, this is a UK retails handset, any help would be greatly appreciated.

Hi everyone.
I'm thinking in buying a phone from CAT (CAT S42) and I'm not sure if I can unlock its bootloader. But I've seen on another forum that the CAT S31 has root available for it through Magisk, and I didn't see anyone mentioning having unlocked the bootloader. S42 has a MediaTek chipset and S31 has a Qualcomm chipset, if that helps.
So my question is: is unlocking bootloader MANDATORY to root a device? Can I just run a custom recovery, root the phone with that, and then the recovery gets overwritten on system boot? Or can I root through USB debugging without even needing custom recovery?
The CAT S31 I mentioned was rooted with Magisk, and as I said, I didn't see anyone talking about unlocked bootloader. But I also read Magisk changes the boot partition and the bootloader checks if it was modified. So I'm a bit confused with this too. It's also written that MiracleBox was used and I'm not sure that's the reason that I'm getting confused or not (I had never heard of this tool until now).
A set of software for obtaining ROOT privileges.

Enter HS QDSLoad 9008 mode from Vol + and Vol- off state and connect without releasing to USB

The Boot image is processed on the phone by the Magisk manager, then uploaded to the phone using Miracle again from the computer.

How may they have done that?
I'm sorry, I don't understand a lot of the root requirements part, since I was lucky and my 1st phone had the bootloader unlocked alreaedy for some reason and the second was as easy as writting a single command. But about this phone there's almost nothing and I'd like to know the general about this. If it's really necessary to have the bootloader unlocked, for example. And if it's not, then what methods can I use with it still locked?
Thanks in advance for any help!
Hello DADi590,
Unfortunately I can't answer all of your questions about S42. I have one of them and I am also looking for and confused with root procedures. But I can tell you that unlock boot loader was just a matter of get developer options on (tapping version # 10 times), and inside you can toogle lock/unlock bootloader...
How to root it safely is what I do not know yet.
good luck!
@DADi590
Rooting the Android OS of a device in practice is nothing more than adding the su cmdlet known from Linux OS to the Android OS. To root Android OS in no case requires device's bootloader must get unlocked to do so.
FYI: The bootloader of an Android device is comparable to the BIOS of a Windows computer.
Actually, after some time I decided to leave CAT alone and buy a Blackview one. If I'd break the phone, at least it wouldn't be as expensive as the CAT S42 (I bought a BV9500 - not Pro or Plus, the normal one).
Since then (with help of adventures with a tablet of mine) I've learned some more things. One of them I was suspecting and was now confirmed (thank you @jwoegerbauer) which is to root the device, just a binary file is needed to be on the correct place: su. I didn't know it was on other Linux OSes though. Interesting!
So the idea is that just a recovery must be installed to root a device. That's it and nothing else, I believe. To install the recovery is the part where one might need to unlock the bootloader - or not, if the chipset manufacturer left a tool to write partitions directly, like MediaTek or Rockchip. On these 2 it's possible to write partitions directly with a locked bootloader (this means the bootloader on my 1st phone was and still is probably locked - like my BV9500 one is, and I flashed various partitions on it already, one of them, a TWRP recovery).
This explanation is for anyone else like me who would have this question. Bootloader is just to flash partitions and I think run modified ROMs too, but not too sure about that (I never use custom ROMs). [Btw, if I said something wrong, I'm happy to be corrected!]

I believe I asked this because I prefer that it's not required to unlock a bootloader to do stuff. If you screw the phone somehow with the bootloader locked and there's no tool to flash partitions on it and you must be on fastboot with an unlocked bootloader or whatever, you just bricked the phone. And I'd prefer that not to happen. That's why I chose to buy phones that don't need me to unlock the bootloader to do anything on them. That might mean I can't ever brick them (at least I never bricked my 1st phone with the various things I did on it which I later found out not being recommended at all XD).
I've unlocked the bootloader on my Cat S42. Can be done.
I am 99.9% certain that I will be upgrading to a Pixel 4a in the near future. Naturally, I will want to root. Is it possible to change/create custom boot logos/ splash screens after unlocking the bootloader? I have been able to do this with my multiple Moto phones. Unfortunately, my LG G6 was/is stuck with the hideous Unlocked Bootloader warning. While I can live with it on the Pixel as well, it would be nice to be able to change it, if possible.
Thanks!

I don't think it's possible. Bootloader on Pixel phones has a menu included... don't really think you'll be able to do that, or at least I don't know how to.
No, and you'll get a bootloader unlocked message at every boot. However, you can skip it with a double click of the power button. This is the same with any modern phone tbh. My samsung galaxy tab S 10.5 has the bootloader unlocked and it doesn't look like anything is changed, except for the lineageOS boot logo
