[Q] aussie Razr M bootloader unlock

According to this review, the Australian Razr M can be bootloader unlocked.
http://ausdroid.net/2012/10/30/motorola-razr-m-review/
I went on motodev and can't find any instructions pertaining. I assume this is not the developer version, so how do we unlock or check whether its possible? Does anyone know / has anyone tried on an Australian Razr M?
Is it as simple as fastboot oem unlock? I tried that and this is what happened
C:\Users\jlo.APBC\Dropbox\android\fastboot>fastboot devices
TA676001L3 fastboot
C:\Users\jlo.APBC\Dropbox\android\fastboot>fastboot oem unlock
...
(bootloader) fastboot oem unlock [ unlock code ]
OKAY [ 0.014s]
finished. total time: 0.014s
??? I didn't get any prompt to unlock or anything.

This is for the RAZR i, but the process is the same. You have to get the Device ID, enter that on Motorola's website, and then it will give you the data you need to unlock. Just follow their instructions, and use the thread as a guide also.

thanks, got the code in my hand
Waiting for some goodies to actually come out ROM wise before taking the plunge, also run the hardware in a bit and be sure 100% no hardware issues
Does anyone know, does simply unlocking the bootloader bar the path for future OTAs? (if you don't do anything else).

Hmm...just by getting the code, you may have already voided your warranty. I'm not sure, though, so don't quote me on that.
As far as OTAs go, no, you will still be able to get OTAs. You would only not be able to get OTAs if you rooted and uninstalled some stock apps, or if you installed a custom ROM. I wouldn't be doing either of those right now, anyway, since I don't think there's a fastboot for the Australian M yet. Once somebody puts that up, you're safe to do whatever you want.

Yep by fastboot you mean fastboot flashable system image right?
Always been my rule as well.
I just reread the fine print and it does seem that they want to screw you out of it if you even request the code. That is so lame...
(I get mixed up between different vendors and methods lol... RUU for HTC... fastboot image for moto... odin image for sammy etc.)

Yup, a fastboot is a flashable image. The stock fastboots allow you to go back to stock just in case you flash something else and you can't boot up again. It's a good rule to have. Hopefully, the devs here will get the fastboot. I think there's a way to make a fastboot from a stock phone, so even if we don't get a leak, maybe that's a possibility. If you think you might be interested in helping, talk to mattlgroff or p3droid (jimmydafish on here).
And yeah, I figured that would be how they determined to void the warranty. Motorola doesn't have a way to know that you actually did unlock your bootloader, because you can technically relock it. So, the request for the code is their way of keeping track. Lame, but I can understand the reasoning.

Well for HTC if you relock, it says 'relocked' not 'locked' in hboot.
Still I guess they warned you but in small print, I was expecting to not pop my warranty until I actually flashed my damned unit.
I'm curious about how much dev work we'll get bearing in mind we're a different variant to the US razr M and different radio, or we will get ROMs that don't touch the radio, etc. etc.

OK so I'm unlocked and have recovery installed. I'm keen to help others and make a flashable fastboot of Telstra's stock ICS system. Can anyone give me any tips on how to do it if it's not too difficult and I'll then upload for everyone to safeguard their phones.

I recently purchased a Telstra RAZR M (My first Android) and am keen to look into flashing a custom rom. I'm willing to help out with an upload of the stock rom as well if needed, lets get this ball rolling.

This is a rather uncomplicated thing and I'd be glad to help you get stock images. would you care to get me a little information?

P3Droid made an app that backs up the partition images into and XML.zip and we can use it to make a set of images from the Telstra M.
We are particularly interested in the radio image to see if its possible to flash onto VZW hardware to have an unlocked GSM/HSPA radio.
The process is very simple, you just run the app and it creates the zip file and then you can upload the images for examination.
These images can then also be used in fast boot to restore your phone as well, of course.
Edit: I see he has responded above. Thanks!

Ok will check the app and get to work.
Can't seem to find the app... Any help?

What info u want? Unlocked, rooted Razr M (Australian version) running stock telstra firmware. Have recovery installed.
Sent from my Razr machine

pj i'm guessing as you have changed your recovery whatever you extract can't be the 100% stock all in one fastboot image though probably possible if you reflash the stock telstra recovery. just guessing

I'm sorry, the app is not available in the market. He posted instructions in the thread in the general forum for the AU fastboot images for pulling the radio image.
He will probably release the app soon too, I was just suggesting it as an easy way to get this done...and now it has been taken care of.
Thanks!

so back to basics: how/when can we get a fastboot stock Aussie M image so paranoid/scaredy cat guys like me can unlock and flash with peace of mind of having an easy stock image rollback option?

Potential way to unlock bootloader?

Since we are using engboot, write protection seems to be off, so it appears you can use dd to write to normally write protected partitions such as the bootloaders (ex: "dd if=/sdcard/aboot of=/dev/block/sdd10"). In my testing I was successfully "dd" a backed up aboot (secondary bootloader) partition and also write to the modem partition and have it stick (which means write protection should be off akaik). If you were to "dd" the Chinese bootloaders, you might be able to flash and re-partition onto the Chinese firmware and then use the CROM service to unlock the bootloader from there. I personally don't know too much about this type of stuff and haven't tried to actually "dd" the Chinese bootloader, but for those more knowledgeable, could this potentially work?
Partitions likely needed are:
- rpm (Resource and Power Manager / Primary Bootloader) located at /dev/block/sdd1 (/dev/block/bootdevice/by-name/rpm)
- aboot (AP Bootloader / Secondary Bootloader) located at /dev/block/sdd10 (/dev/block/bootdevice/by-name/aboot)
- xbl (Extended Bootloader) located at /dev/block/sdb1 (/dev/block/bootdevice/by-name/xbl)
- ? located at /dev/block/sdc1
Modifying the bootloader is dangerous and could permanently brick your device. I take no responsibility if you try this and it breaks your device.

Lets start a thread . . .

$25? Hell think about how much we spend on the phone itself and bill every month.. I'd easily pledge $100 for an unlocked bootloader with twrp support.
That's the 1 thing I don't understand.. this is the most highly sought after phone right now with 0 developer support. I understand the limitations with the locked bootloader but other phones have overcome the same through the works of various motivated individuals. There is no one even interested in trying it seems on ANY carrier forum. Instead we have countless threads with people more interested in getting the nougat update early which will hardly provide anything useful compared to an unlocked bootloader with working root.

Root right now is just too impractical for most people. I'm still rooted, but for most people it isn't worth the hassle and trade-offs, for many it's worse than stock. I think most people who are really into root probably switched devices. Switching to android N could actually prevent bootloader unlock in this way, unless root for N comes out. That is if this unlock method could actually work, hard to say without anyone experienced in bootloaders and write protection though.

I'd like to find someone with a sm-g9350 to DD a dump of sdd10.

Sdd1 is the primary bootloader, probably also necessary.

Came to the realization that the Chinese bootloader is v2 where all US models are v4. I'd imagine the Chinese nougat update will make it v4, so we wait to try.

Don't want to a be downer or anything but I'm pretty sure you can't just replace the bootloader, even if write protection is off on the Eng kernel. Even if you did replace it you'll have probably bricked your phone.

The thinking is that since the devices are virtually the same hardware wise, there is a chance the bootloader could be replaced. I do agree that there is a good chance of hard bricking though. I haven't done any testing other than apparently successfully dding a backed up version of the same bootloader.

If I wasn't on nougat I would try it if someone posted instructions and devs confirmed the directions are correct..

I was actually playing with the bootloader, and found this thread when I went to post. I'm going to be pulling fastboot commands also to see if I can find anything interesting. I'm tired of not being able to use a custom kernel

My device is on nougat. Bit I can easily downgrade and test if someone has a rock solid idea. I don't mind bricking as the device has a cracked screen and I have my s6 edge plus to use until the s8 drops...

Count me in as well!
I have a theory that we can open the BL file in WinRAR and extract the rpm.mbn file from G9350 odin file,
and flash to our device. But I cannot determine which one is for aboot. I have not tested this yet.

What I know is:
RPM = Resource and Power Manager = Primary Bootloader
ABoot = AP Bootloader = Secondary Bootloader
I believe the boot process is "RPM > ABoot > boot.img (Main OS)", so both the rpm and aboot file would be needed. Also I think the partition layout in the Chinese version is slightly different, so a flash and repartition would be needed after replacing bootloader to actually root. I don't know what the chances success are though, the devices are virtually the same hardware wise, and the Chinese rom with the U.S. bootloader works according to the Verizon fourm, but there is a chance there are other differences what might prevent this from working.

Isn't fastboot disabled on the s7. Also, were your results the same?

Yes, found that out when I started playing with it more. I'm currently reading sdd10 line by line. I did find an entry "Device is unlocked! Skipping verification...". I'm starting to think we need to look into recovery-side exploits. I'm too scared to try and mess with the bootloader too much.
EDIT: If we can find a way to get fastboot working, possibly piggybacking off of Odin, I found a command written in the aboot code 'fastboot oem unlock-go'
EDIT2: Using that command requires some sort of key. May be a dead end.
EDIT3: I'd be willing to test modifying the recovery image to see if it triggers the bootloader's hash checking. If anything, this could lead to writing a custom boot image that would open TWRP.

Stock AT&T m7 to Nougat journey by an Extreme noob!

Hi guys, well the heading says it all. my phone is an ATT model & i live in srilanka so ive never got any ATT OTA updates. phone is stuck on Android 4.3.
recently started getting random reboots which i walked around by disabling "google play services".
now ive got a wired boot loop issue which happens from time to time. boot loader->recovery->clear cache option dont work. i get a mini M7 pic with a triangular caution/Exclamation sign the moment i hit recovery.
i do love my phone though & im hoping to get a couple of more yrs worth of use. i would like to solve the bootloop issue & upgrade at the same time by going to a Nougat ROM (suggestions welcome, i read AICP is good!!).
if ive got my reading right, i need to do things in the following order:
1- backup EVERYTHIING
status - done
2- Unlock bootloader.
Status - inprogress
im watching this guys vid - https://www.youtube.com/watch?v=QU7vi388dMk , but his fast boot folder already has the unlock_bin file in it. the vid details a long process via which this file should be gotten by email from the HTCDEV site. anybody know why that is? help!
3- install TRWP recovery.
Status - TBD
4- Flash ROM.
Status - TBD
hoping the collective genius here can help a bloke out.
SK

Note that you need to do a NANDROID backup, and save your storage as bootloader unlock will format the data folder

The Unlock_code.bin will only work on the device it was generated for. You must submit your unlocktoken to htcdev.com to get your Unlock_code.bin:
Create an account at HTCdev.com, then "fastboot oem get_identifier_token", copy/paste your token on htcdev.com and you'll receive your Unlock_code.bin from htc. Then flash it on your phone (fastboot flash unlocktoken Unlock_code.bin) and you're done.
You also probably want to go S-OFF since most recent roms will not work really good on old firmware, if you want to flash a Nougat rom, you probably want to use the latest GPE firmware and for that you'll need S-OFF.

How to get a fastboot console in bootloader

Hey guys, I found this quick and tidy way to get a fastboot console inside the bootloader. You can use it to do stuff like "fastboot format (partition)", etc.
GUIDE:
Go to fastboot mode on your Pixel XL
Open a CMD on the computer in fastboot directory and write in "fastboot flash bootloader pixelcustombootloader.img" (make sure the bootloader is in the directory or else it will not flash!)
Download: s000.tinyupload.com/index.php?file_id=44700284262726497364
Note: I am NOT responsible if this screws up anything.
Also I do NOT know if theres and copyright trouble with this, if there is, Mods go take this down.

I wonder if this is the bootloader that was seen in screenshots that was used to downgrade a Verizon pixel to unlock it?

If the bootloader is locked you can't flash anything or boot anything that isn't signed by Verizon/Google/whoever.
As far as I know there's never been a downgrade workaround available where pixel8 wasn't patched, but could be wrong.

There was a guy positing pictures of someone from a cell phone shop where he was recording the procedure that they did to his phone it was a signed bootloader that allowed him to downgrade for an unlock. It was labeled HTC which people thought was weird.

Eh.. 3rd party pictures that don't come with a detailed "how to" are 99% BS or marketing.
Like I said I'm not all knowing but I'm pretty in touch with the goings-ons of the pixel and have never heard of a downgrade method for a locked bootloader.
If this shop has a private method of doing so then they sure as hell wouldn't let someone take pictures of the process.

Yea like u said the guy said they were spy shots that he snuck in. Probably bs like you said. I could careless for myself my Verizon pixel is unlocked. Feel bad for those stuck locked though. Wishful thinking I suppose.

Yeah, don't flash your bootloader with anything other than stock google imgs. If your bootloader is messed up, how do you get into fastboot to fix it? Can't change slots either afaik.

Thanks for sharing, this has loads of potential - could be used on-the-go to temporarily recover from the freeze/reboot glitch (flashing stock images tends to lower the probability of the glitch for a day or two), plus we could actually have tetherless TWRP support for Oreo with this as you could use it to fastboot boot the TWRP boot img.
That being said, I'm reluctant to flash a random bootloader on my phone with no info on where it came from. Did you make this? If so is it a patched version of the most recent bootloader? If not, where'd you find it? We need more info.

Bootloader unlock without unlock code from Huawei

Is it possible to unlock the bootloader without the unlock code coming from Huawei itself?
I want to unlock the bootloader. Many pages on the web (and on this forum as well) say I need to get the unlock code from huawei, but... it seems that huawei is not collaborative any more: Honor/Huawei’s bootloader unlock page disappears with no explanation
Can I work it out without the code?

Actually, what I really want to do is...
Actually, what I really want to do is...: install a different firmware.
I'm a real noob in the world of modding & custom rom.
As far as I understand, unlocking bootloader is required in order to install a different ROM: is it right? or can I install it somehow even with bootloader locked? Also, can I root the P8 without unlocking the bootloader?
My P8 is on the latest firmware I recently received OTR from Huawei: GRA-L09C02B405. The phone is starting to have some problems: hight battery drenage, UI freezing and rebooting from time to time.
I'd like to install a previous version of Huawei official firmware, or different a custom ROM (I read about some of them in this forum: any suggestion?). But as far a I understand, unlocking bootloader is required, and it seems that without the code from Huawei I'm blocked

Ik zit met de zelfde vraag, ook mijn P8 kan ik niet unlocken website van Huawei met deze optie is verdwenen.
I have the same question, also my P8 I can't unlock Huawei's website with this option is gone.

You now have to contact Huawei and request it, providing IMEI, SN, Product Code, Model, and reason why you wish to unlock it.
Here is a link to contact the UK (most people say this is more successful than others) :- https://consumer.huawei.com/uk/contact-us/

For both, yes, you need to unlock your phone. For rooting, you have to flash a new boot.img, and for a custom ROM you have to flash the system.img too.
Without the unlocked bootloader you are unable to flash the images /partitions

For both NO, however it tends to be a bit easier if the bootloader is unlocked. Some third party rooting apps may or may not work, depending on what version OS you have installed, without changing the recovery partition.
However it is usually easier to root by flashing with TWRP etc. which necessitates an unlocked bootloader to allow you to flash the said recovery.img and then flashing SU.zip for example.
The same goes for flashing a system.img ( does not need an unlocked bootloader ) eg. use fastboot mode and an ADB shell or even DLOAD if it has the correct signatures. The caveat is that most if not all custom ROMs use a proprietary boot.img so an unlocked BL will be required in this case.
Hope that clears it up for you.

I asked Huawei for the code, now I'm waiting for reply.
So, if I understand correctly, even without unlocking bootloader I should be able to flash a previous version of an official firmware, ain't it? I can consider that option if I don't get the code from Huawei
Thanks a lot, you are being really helpful

Bootloader unlocking is not needed for upgrading official firmware, unfortunately, normally it is a completely different matter when trying to downgrade .

So, it seems that I really need Huawei help to do something more or less useful for me. They made something such a "unhackable" phone which can be hacked only with their support. And more or less every other vendor I assume.
Quite weird I think.

AFAIK Huawei are/were the only vendors that made it so easy to unlock the BL, esp. when their code generator was online.
Have you heard back from them yet, some people report getting the code within 12 hours ?

I got a first mail the day after I wrote, with them asking to add the reason for the code request.
This morning I answered them them that I wanted to play with root rights & custom rom, and that I was aware of the risks implied.
now (6 hours later) they sent me the code.
Quite a good support I'd say

Yes indeed, the reason why, as I said in my first post, wonder why they're interested ?

You now have to contact Huawei and request it, providing IMEI, SN, Product Code, Model, and reason why you wish to unlock it.

Any way you have it now, I assume it worked OK.

i'm struggling with the same issue. UK support doesn't want to give me the unlock code even if my P8Max is blocked on all google related stuff. I can't even get Google services
after the last OTA update ( DAV-703LC233B226 ) installed anymore. But still they persist that I should send back the unit ...

You can unlock your bootloaders by using DC Unlocker.
