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

Just in case,

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 can't find anything definitive about whether it's rootable or not
Same here i tried every root app possible and failed.

How did you unlock the bootloader?
sCriptKittY1987 said:

Click to collapse
simple , go to about phone and try to find build number,
after you find build number tap on it until it says you are in developer mode
after that head on to developer option (it may be inside about phone section or above about phone section) turn on the option which says allow oem unlock. then,
just reboot to recovery mode either by pressing volume up or volume down key with power button.
after you enter recovery connect usb cable and open command prompt in pc and make sure that lg device drivers are installed on your pc also make sure you have adb and fastboot installed.
ok, after all this type command
adb devices
if any thing shows us then you have successfully connected your device.
after it type
adb reboot bootloader
then your mobile should restart and show fastboot mode in screen
type command
fastboot oem unlock
and done your bootloader is unlocked.

I meant TWRP recovery . After you've unlocked the bootloader where did you get a custom recovery to flash for the LG k51. From what I saw on Team Wins website, there isn't one.

I doubt that's going to work, but let me know if it does. Carriers and manufacturers use a variety of sophisticated security schemes like requiring lengthy codes that only they can provide, etc to purposely make it very difficult to unlock bootloaders. Tmobile gave me a K51 for free. They apparently feel the have to pay for it by spying on me. I bought a moto g7 plus unlocked for $117 directly from Moto and put Lineage on it, no gapps Would love to use thie k51 though if anyone figures it out because it's more waterproof and bigger battery.

Whether device's bootloader is unlockable / device's Android is root-able or not you easily can find out by means of ABB:
Code:
adb shell "getprop ro.oem_unlock_supported"
If returned value is 1, then it's supported otherwise it's not.

and let me guess my doofus luck im guessing no way to unlock it with out a P.C. like nuttin at all?
Absolutely no of the crap above works at all in any capacity especially sprint. Generic postings like hold volume down and power also doesn't work to go into fastboot so if you guys are following the advice of some of these guys don't because you'll drop more money on a new phone then you will unlocking it some variants verizon is one I think you have to call LG I know I spent 6 hrs on the phone with "tech support" aka "jokes with a screen to read from" to FINALLY get into touch with an engineer who told me the only way "NOW" to unlocked the bootloader is in his office which means it has to be depot to be unlocked which as of this moment lg is not doing that WILL change in the future that was 12/03/2020. Even running external adb with kali linux to hack it broke the bootloader and sends you into an infinite reboot loop

This returns no value on a locked bootloader because even with Dev. Opt. Enables its still read only until bootloader is unlocked this is verified on two carriers k51's sprint and att. However it is unlockable we haven't found it and/or LG has not added this service to their site which is where you will get the info needed for the unlocked.
Oh my. You know you need to do all this from a computer, right? Can't do it in an Android terminal because fastboot commands are only valid in a phone's bootloader environment. And if you didnt know that then rooting and all of the dangers that come with it just isnt for you. But yes, it's rootable. So here you go anyway.
Reboot the phone to download mode.
Install LG's K51 usb drivers, and install adb and fastboot, on your computer.
Open a command prompt and type: fastboot oem unlock
If it does anything other than pat you on the back and tell you it's proud of you and how well you follow instructions, then go back and follow the effing instructions.
Otherwise, type: fastboot reboot.
Download magisk manager.
Do the magisk manager.
Use the LG flash tool on your computer to flash what you just did when you did the magisk manager.
And presto, you're rooted. Or I successfully left out enough info and you dont know how to use Google, leaving your device still not rooted. And thank god for that.
Ive been learning from xda for some time now. Bricked a few phones in my learning curve and tonight i had my first success with my g7, and wrighting this on my new k51. This is my first post and I think that was pretty rude of you to say. This is supposed to be a place to learn, share knowledge, and help those who are less educated. Not look down on people and say crap like that. If he wants to learn even if it takes a couple bricked phones to do it, let him. Either give him the proper procedures or dont say nothing at all. How long did it take you? How many phones? Its taking me quit a while but i am finaly getting somewhere. Keep with it guy. Dont let this dude, or any one else for that matter, bring you down.

Yo Ken,
So your K51 rooted?
If so, maybe you could provide a step by step?
I haven't done this yet but is it verified working? I did a google search came across the method to do the unlocking but it showed it was a failed project?

Hi community
First Thanks to the people who take time to help, and admin that create that forum. Im always glad to see that s there is still people caring about helping each other
I come to you cause I spent the last 2 days trying to fix my brand new phone.
Brand : Xiaomi
Model : Mi ultra
My Computer : MacBook Air
Problem : "The system has been destroy"
Other problem :
- USB debugging OFF (not able to access to the phone in any way)
- Bootloader Locked
How its happen :
After installing an EU Rom, I re locked the boot loader using Adb... And it crashed.
I tried almost everything you find on internet using a Mac and till now nothing worked.
I tried to unlock the boot loader using ADB, which one the only thing who seems to be working and I got an error message saying that the Miunlocktools was too old ... ?
The token was available, as I already unlock it.
Does anyone know how I can switch ON the debugging mode without accessing my phone, or Unlock the boot loader using my Mac.
It seems there is solution possible but using windows computer, and tbh I will not buy a computer just for that.. for the moment
Thanks in advance to everyone
PS : I will offer 50USD straight in BTC to the one who will provide me the solution that will help me to fix it
Locking / unlocking a phone's bootloader is done by means of Fastboot, not ADB.
ADB & Fastboot are 2 completely different things. Don't confuse them.
AFAIK you can't enable ADB ( USB debugging ) from outside, this can only get enabled from inside ( Android Settings -> Developer options ) unless one creates/provides a flashable, properly signed ZIP that contains the code ( read: update-binary script ) to rewrite device's build.prop file entries accordingly.
BTW: A locked bootloader always tries to run device's Stock ROM.
Thanks for your quick answer. In other word, is it possible ? I am looking for what you say.
If I rewrite it, will I be able to switch it ON then ?
Im not at all a professional , that's my first step in this "world". It seems difficult, I will need to read a lot I think
What do you think about the EDL cable also, do you think it can work ?

IDK.
Never have bricked a phone. And I never owned a Xiaomi device.
locking a bootloader (at least in xiaomi phones )results in the phone being reformatted and the stock rom is installed
also try installing the newest version of miunlock https://en.miui.com/unlock/download_en.html
you might have to wait 7 days or less or more or might not have to

Hi
I re locked the boot loader myself so I unlocked it before
Thats the version I have but in the terminal I got a message saying version is too old...
I just wanna learn how to begin the rooting don't know what driver how to get a sdk what app nothing?
I'm looking at the A13 as well since the GS5 is now blocked by AT&T.
I just spoke to Samsung, and they told me the A13 G5 unlocked version purchased directly from them comes with an unlocked bootloader.
I think I just wet myself.

Samfirm should have the version of android you need for you're phone you need the Samsung flash tool su+twrp+magisk is optional good luck! Ps.always back up everything
I will be working on mine purchased from Metro PCS. Its OEM bootloader is locked at the moment. I will be using Magisk and flashing a TWRP. Utilizing an ADB wireless USB connection from PC. I will keep you posted if someone else doesnt beat me too it. Either way this thread is going so im sure together we can knock this out. Im going to do my LG Stylo 4 firsy. Its OEM came unlocked from Metro PCS...so i scored. Just havent had time. I just did my ZTE ZMax Pro Z981 from Metro PCS...it also was unlocked OEM. They will all need a PC usb connection and Magisck. You can find them in threads here. Good luck. Will post again when i get time. Hope this helps a little. Here you might not get an answer you want...but if you dig youll find what youre looking for...just got learn by doing...like they said...always backup... everything...first...dont forget to remove sd before you factory reset or you will wipe it. And your phone. If youre not sure...dont change things you dont know...you will brick your phone. Follow directions you find in threads...and you will be fine. I learned how to be a great chef from other chefs who told me the ingredients but never amounts of ingredients. Thats how you become a great chef and also become great developer...good luck guys. Im learning too. Share what you learn. FYI...the one click....dont bother...IJS...PC you will need for this....

How do you plan on flashing those if the bootloader is locked.....?
Sorry to break it to you, but it's a Samsung thing. It doesn't matter if it's a device from a carrier or carrier-free directly from Samsung, if you buy a U.S. Samsung phone you will not unlock bootloader freely.

Correct
first you need oem unlock on that takes pluging in phone holding volume+/- (both) and power till it shutdown and restarts with the unlock option in recovery
Just bought this but the 5G version
Hi, I just rooted my Samsung Galaxy A13. Here's a quick tutorial of what worked for me:
Prerequisites:
Install Heimdall onto your computer. I used Manjaro Linux as my OS, and haven't tested anything else. Install any drivers if necessary.
Install Magisk onto your phone. I recommend using the F-Droid store/app, or Magisk's GitHub page.
Steps
Install any updates for your phone.
Unlock Bootloader
First of all you need to unlock the bootloader:
Enable Developer Mode by navigating: Settings > About Phone > Software information.
Tap Build number about 7 or 8 times until it says You're now a developer.
Allowing the bootloader to be unlocked:
Settings > Developer Options > Enable OEM unlocking.
Allow it to be enabled if prompted.
Turn off your device.
Turn on Download Mode by holding down Volume Up and Volume Down.
When you see a blue screen, hold Volume Up until it shows Unlock Bootloader screen.
Press Volume Up to confirm.
Flashing firmware
https://samfw.com/ is a good resource for downloading firmware. Be careful that you're downloading the correct firmware though. You can find information by navigating on your phone:
Settings > About Phone, and Settings > About Phone > Software information. If you call *#1234# it will show you the current firmware.
Extract the archive.
Extract the file staring with AP.
Extract the file boot.img.IZ4.
Move boot.img onto your phone.
Open Magisk. Click install. Locate and patch the file. Move the file back onto your computers.
Extract the file starting with CSC. Locate the pit file.
Open Heimdall.
Choose the pit file and the patched boot image.
Put your phone in Download Mode and connect via USB.
Flash your phone.
If it worked successfully, your phone will reboot. It will probably throw an error before starting. Choose to do a factory reset. This will delete all the user data, but the patched boot file will stay in place.
Download Magisk again. Follow the prompts.
To test if you have super user access, install Termux from the F-Droid store. type su into the terminal. You will get a pop up asking if you want to give super user permissions.
Congratulations! You're now the UNIX sysadmin of your own phone!
hello Everyone, a friend of mine from America bought an A13 5G, now we are in Europe and the phone is blocked.
exactly inserting a European sim says:
Phone locked. Please contact our customer service center to unlock your phone.
i tried to unlocked bootloader, but unfortunately i don't have OEM unlock present, no way i get it out!
there is a complicated procedure with Flashing a Combination Firmware, but it looks difficult!!! I haven't done it yet.
but would it be possible to only unlock the phone to use European sims?
many thanks

Unlocking the bootloader would not do anything for you in regards to network unlocking. Those are 2 totally separate and distinct procedures.
What's the Baseband Version on the device? You can find that under Settings-->About-->Software Information (and don't do any software updates to the device if it prompts you to)
Hello, the first thing would be to unlock the bootloader which is very easy in Samsung terminals, In all Samsung is the same, you can see the following video that I recommend. No PC needed, The video is in Spanish but it is only to follow the same steps:
The second thing would be to get root, the easiest would be with Magisk, I recommend you watch this video since it is not necessary to format the cell phone, the video is also in Spanish, but you still follow the same steps. In this case, a PC is necessary:
Soon I will make a post myself, teaching you how to root without losing data, the same way as in the video, in case you didn't understand the video.
There is no boot.img.IZ4 im my ap file
ok i found the boot.img I extracted the ap file with winrar before. some how it does not see the .img files but untarring on linux worked. i managed to re flash the ap fille with odin and i saw lot of .img files being flashed and the extracted foldersize by winrar was way smaler than the archive. so that made me look at the ap file and i got the boot.img patched by magisk and made an lz4 file out of it how do i get that boot.img.lz4 back in the archive?
also whats wrong with fast boot?
"fastboot devices" lists my device when its connected but like many here post it does not work with other commands it failes like thIs :
fastboot flash bootloader b.img
Sending 'bootloader' (32768 KB) FAILED (remote: 'unknown command')
fastboot: error: Command failed
Tried other examples too but nothing works tried the fastboot included in android studio and one of the minimal adb/fastboot. the boot loader is unlocked (Not using fastboot) and odin works fine. my phone is in the "entertering fastboor mode" state .its a samsung galaxy a13 g5 and i flashed this firmware using odin
AP_A136BXXS2BWA1_A136BXXS2BWA1_MQB61124574_REV00_user_low_ship_MULTI_CERT_meta_OS13 now its stock again with no accounts.
fastboot reboot does work so some is right.
fastboot reboot
Rebooting OKAY [ 0.001s]
Finished. Total time: 0.005s
i hope some one can point me in the right direction.
thx

Fastboot isn't functional on Samsung devices. Samsung replaces it with Download mode. Therefore, all flashing is done via Download mode using Odin, not via fastboot mode using command terminal
Ive looked for hours for a way to do this myself and i keep coming up short. Ive tried using fastboot method and it wont work. Its got a qualcomm chipset. A couple guides that i did find used using fastboot commands but they didnt work and i cant find anything else so far. The tablet is carrier unlocked to the best of my knowledge. Please guys if anyone could point me in the right direction i have no problem with doing the work i just need a nudge or even a possible solution if anyone can help. Thanks in advance for your time and attention to hear me out and for any help you could give.

Tablet's OS is Android 11 GO, it got released 2020.
Is "OEM Unlock" option provided in Developer Settings? if so have you turned it on and afterwards rebooted the tablet?
Have you installed the Fastboot driver that's suitable to tablet?
If Fastboot returns "FAILED: (remote: unknown cmd.) " then Fastboot is obviously not supported.

Are you talking about the M8L 2022? I've unlocked the bootloader but can't get it back to recovery and its FRP locked so i can't use ADB. ugh.
Also, its a Unisoc chip I think.
You have to use a modified fastboot and get the identifier token.

Look up modified fastboot for spreadrum devices. There is also a guide on hovatek forum.
For anyone and everyone who has had any trouble locating the firmware files (.pac) for the 2022 BLU M8L tablet, I FINALLY, after more than a month of searching found them on needrom.
Link is: https://www.needrom.com/download/blu-m8l-2022-m0220w/
Since idk if the link will be redacted or edited out, you can also google needrom and M0220WW
Be carefull when downloading the fireware for the M8L and pay close attention to the version your needing. From all that I gathered, there are mutiple versions...M0170WW, M0171WW, M0173WW, M0174WW, and the one I have that I have yet to find anywhere on the net. Its the most recent ..the M0176UU. If anyone happens to have this version, please make a full backup image and post it here. Thank you
