Hello everybody,
I have a question about bootloader. I have searched before I asked. But most of the thing I got is something for someone who've already know what bootloader is.
So my first question is "What is bootloader?"
And everybody here seem to be happy with any manufacturers that they unlock the bootloader.
So my second question is "What will we get/earn when the bootloader is unlocked" or "What a unlocked bootloader can do?"
Or if my question is common and boring, please send me a link, or a page or something that I can get my answer.
I've searched before I asked but any information I got is for people who already know what it is, like bootloader update news or something new to do with bootloader.
Thank you.
"What is bootloader?"
in my understanding the phone company doesn't want the customers to install other roms beside the official rom provide by themself so they make "bootloader " as the "key code" to protect from installing other rom the official roms sbf
"What will we get/earn when the bootloader is unlocked" or "What a unlocked bootloader can do?"
the developers can totally modify and control and test and make us more roms ..you can install and exprience more roms (OS)with more features such as Miui ,cynagonmod nad many others
now that our XT720's bootloader is locked so the devs can only modify with limitation and can only make our rom base on old kernel..is bootloader is unlocked..they can get us more rom with newer or better kernel
The locked bootloader prevents using a custom kernel. So we can only use the original one. The kernel itself cannot be optimized or customized. So we can get features like swap support only using fastboot with usb connection to PC.
Additionally, the bootloader is the phone's version of BIOS if that helps. Unfortunately, there is a lot of misinformation out there. I used to be very confused about this, too. This is what finally cleared things up for me:

There is more detail about the boot process at droid-developers.org
Now I understand what it is.
Thank you all you guys for your enthusiasms.
Wow very interesting paper!
Thanks for sharing it!

thanks ,i learn alot from your link
Hey guys, im new to this forums so first of all, hello everybody.
so, i have this xperia l, and im not new to android devices, and i want to flash a kernel and a rom (more specificly, thunderzcap and ios7)
the problem is, i cant unlock my bootloader. In that screen after you type that weird combination of numbers in the dialer it says that i just cant do it (not allowed). I read it somewhere that i need my simlock code and something else, but according to what i know (and i dont want to believe t) this means it is permantly locked.
So anyone here knows how to solve it? I would defenitly love to unlock the bootloader so i can flash a kernel... or im stuck with my phone? i know there are other roms but it isnt the same thing...
Thanks in advance
If it's locked there is no going around it. So answer is no, if it says on the phone that bootloader is locked you can't unlock it. And there are NO roms that work with locked bootloader. For you to be able to flash a ROM on it you must have unlockable bootloader.
Sorry to give you bad news but that is way things are in your case.
Nothing you can do.................for now.
If we can get CWM going on the phone, we can flash packages. From there, if this can be extended to our phone, http://forum.xda-developers.com/showthread.php?t=2595238 then we can run CM variants on top of stock, and thus there is hope for the locked bootloader people, like myself, hopefully.

Thanks for your enthusiasm but my method does not Unlock the bootloader so you should change your thread title.
As I told you I will open a thread when the method is fully tested by a few advanced user's who are testing it now and you will be given full credit for all your help.
I do not want to risk anyone bricking their phones due to rushing. Many none advanced users bricked their sony c4 phones by Not following my instructions so I need this to be 100% clear and fully tested I hope you understand.
I understand you @bigrammy by flashing twrp bootloader will automatically unlocked !

If the bootloader was unlocked fully you would be able to use fastboot to flash the device but we cannot so the bootloader is still locked to all intense purposes.
The secure boot chain does appear to be broken so we can use SPFlashTool to flash and boot our TWRP recovery but the secure boot chain may still be working if you have never unlocked the bootloader before like on Android 7.x. This means TWRP may Not boot up for everyone. Like I said it needs to be fully tested.

Actually, spflashtool bypasses the bootloader in this instance, so the bootloader is untouched and you still flash twrp

Not to be pessimistic, but you do realise that even with all your precautions,people will still not read properly and will still brick their phones, no matter how many precautions you take. Even if you had an app that requires you to click one button to do everything,there are still people who will do it wrong. That said I think I know of one or 2 people in this Nokia 3 forum who were able to recover their phones using spflashtool AFTER the phone couldn't even be detected by their pc, even OST flashing was not possible .
Another thing is, all the Nokia 3 is last year's phone, I wonder how many experienced users will be buying the phone now, and experienced people are probably not the best way to get something 100% tested, because they know the right steps to take.
I think you should make your method public after you hear from SkaboXD

Sorry I replied to your PM before seeing this.
True there is no accounting for people but I don't want to get bogged down by noob's. If you and maybe SkaboXD would like to open a thread and manage it using the method then that would be fine by me as long as credit is give to Riadh300 the original tester and who informed me SPFlashTool still worked and myself of course.
Please read my PM about the bootloader condition as I recommend only previously unlocked devices try this for now until tested by Advanced user able to recover the device should anything go wrong (EFuse Blown).

Alright I understand your point now. One thing I wonder though is: would someone on nougat who has never unlocked bootloader be able to flash ost?
Just checked my phone, oem unlocking was set to off so you're right, your method doesn't actually affect the bootloader.
I actually don't mind posting your method and giving you guys the credit, I just thought that you would want to be the one to do so.
Anyway I'll wait to hear @SkaboXD thoughts before I decide on whether to put up the post

Before on 7.0 I flashed a TWRP I was working on via SPFlashTool bootloader locked and ended up in a never ending recovery bootloop which none advanced users may find difficult to get out of now this may of been because I screwed up the TWRP or more likely because the bootloader was Locked.
I did not try any other TWRP's until I was bootloader Unlocked and I have not had the recovery bootloop since.
Not sure about OST as SPFlashTool is by far the best tool for MediaTek devices and recovery of said devices remember the SoC manufacturer knows best and I only ever see problems when the OEM's try to move away from it like Sony did.
Happy for you to take the lead I am too busy in other threads to worry about it

I will lock bootloader and try this method of rooting. I think that is this the best method because it doesn't affect bootloader so you can have OTA updates. Just what is the root manager, SuperSU or Magisk?
I think that we could make a thread when this mehod is tested on both Nougat and Oreo with locked bootloader. As far as i read, Oreo is tested so only Nougat remains to test.

OK, one thing though, before flashing the recovery you might want to do a backup of the stock recovery if you don't already have one. That's what I did, so after I got root, flashed back my stock recovery. Magisk is the root manager ,

oh you mean you went through hoops to get your phone back? I thought you would say you got a stock recovery somewhere and flashed using spflashtool or used the ost method. I didn't actually expect you to outline the steps you used. BTW, first time I flashed twrp AFTER unlocking bootloader, I got stuck in a recovery bootloop too. I had to flash my phone with OST then retry the process again.
One other thing, I think OST is actually a propriety software that is supposed to work for lots of phones, at least I know that users of other non mediatek Nokia phones also use it to recover their phones (with the corresponding stock images of course)

Magisk hide allows you get OTA's see the Magisk thread and yes it will work on any android version.
@redweaver
I am glad you got out of the loop but your clearly a more advanced user hence why I ask you to test. :good:
The OST is very convoluted for use on MediaTek devices and is very unnecessary it also requires unnecessary FIH software to be installed on the phone to work properly.
They likely choose this method to work across different SoC's but it's not what MediaTek use SPFlashTool is MediaTeks own software.
EDIT: Sorry lost internet for a while then.
I continue: Good news is I do not think they will be able to remove SPFlashTool use as it's binary on device which lives on a none volatile area ram chip or radio chip and is loaded at the factory so I doubt it can be updated via a OTA. :fingers-crossed:
Sony actually replaced this and this is the only device I have been unable to recover and even Sony were replacing the boards of bricked devices but if they had left the Mediatek binary in there it would not of been a issue as SPFlashTool would of been able to recover them. :good:
guys, old thread, i know, different device, i know, but ive been in the dark and this is what most resembles my issue.
any hints would be appreciated, read all 2 pages, can you believe it? im a very average xda enthusiast.
worries out of the way, my sincere thanks beforehand follow.
issue
carrier doesnt get in the way
oem doesnt get in the way
oem unlock toggle, check, adb debugging, you and i know the drill, no driver/cable issues
cannot for the life of me unlock bootloader, this one would take the newer command, however i tried them all ive come accross to no avail
output encourages me to unlock first, howwever not a clue is given as to how to accomplish it. this isnt the flash a file type of unlocking, either, at least not oem provided. going nuts.
go ahead and feel free to issue "advanced" directions (meaning, like your voicemail, instead of "for voicemail configurations press 8" and just "configurations 8"
spreatrum, not mtk
x120c
came with oreo go, treble enabled per getprop
i dont know what else, please
so first i want to apologize for posting in the wrong place but this phone doesn't seem to exist anywhere and I'm having trouble with getting the bootloader unlocked and installing Magisk (if someone could tell me where this should have been posted I would appreciate it allot)
I followed everything on the Sony open devices page checked if it was allowed got my unlock code for both IMEI (dual sim device) just in case that would be a problem now getting into fastboot was more difficult than I was expecting (Sony devices their screen stay black on fastboot which I haven't seen before) but I forced a driver update through device manager and now its being recognized by fastboot but it just gives me the error:
FAILED (remote: 'Command not allowed')
fastboot: error: Command failed
now after looking around online (some people suggested that it might be unlocked already but I'm not allowed to flash Magisk so I don't think so and i cant check the screen during fastboot as everyone suggests because it stays black)some more trying to find anything I found a post about allowing OEM unlocking through developer options and that's where I got stuck because my device keeps doing this
currently i rather bin it because this has already taken days from my life but I refuse to turn this into another €200 paperweight (I really hate e-waste) so i hope someone can help me get in the right direction again
sorry for my horrible posting (and grammar) I never do this and thanks to anyone who takes the time to read this
A friend wanted to root this phone... I guess he won't.
This is the only post I found about it, thanks for your feedback and sorry for your loss haha!
I have a A125U that I can't unlock the bootloader of. There's no OEM unlock option in the Developer Options, there's no way to unistall system updates to try the date/time thing to get OEM unlock, nothing else I've tried has worked at all. I even tried flashing A125F firmware to no avail, of course. I was thinking, the BL file is the bootloader, is there a way to flash a bootloader that's already unlocked? Or is that not how this works?
If not, does anyone know how to get OEM unlock to show on the A125U? It's been driving me insane.
Not possible unfortunately
no
LOOOOOOOL
This is the biggest lie I've ever seen in my life!!! of course it,s possible ddd. Everything is possible especially this. Trick to your issue, is just that you have to corssflash to the Canadian firmware on your A125U which is the US model. But that doesn't matter, that's nothing because those 2 phones run on the same hardware so the firmware operates with both. Even the SW_REV value doesn't do anything in that situation. You can take the U models and flash it to W(Canada) but that's useless because then you're locked out of natively unlocking the PBL. Just grab the Canadian firmware and crossflash it via heimdall or patched Odin which is the same thing. Erase old NAND.
Also don't think that stuff like this isn't possible, of course it is. You just have to try harder and harder until you get the result you're stasifed with. There is community with a bunch of us enthusiasts (discord server link is on my profile). Don't be scarred to ask here on xda and there in the server. Also you can dm me for help, I'll help you, don't worry.
Hope I helped, be sure to ask if misunderstood or need more help. Also check out some stuff i wrote on this forum. It's very helpful and interesting.
Stay safe,
