All custom roms with bootloader and a req to devs - Xiaomi Redmi Note 3 Questions & Answers

A REQUEST TO DEVS
There are different sources for developing roms now,but some of them have a MM bootloader which needs to be re unlocked again.so i request devs to add the status of bootloader(will their rom keep the bootloader unlocked or will it lock it).This would be very helpful for me and some others as i see there is always questions on the roms threads about the bootloader status.

How to unlock relocked bootloader?

The same way you unlocked it first. Or restore a backup that you made with unlocked bootloader.

Hello, If we restore à backyp, the bootloader is unlocked ?

Yes, if you made a full backup. I made mine with Alka TWRP, and restoring (never restore firmware partition!) sets the bootloader back to unlocked.

Ok thanks I restored everything just not the firmware, it's that ?

Check it yourself. Put it in fastboot mode, and do "fastboot oem device-info".

Not sure...
I am not up to speed on cm7.1, but you can try it and see.
My initial thoughts (Anyone please correct if I am wrong) is that cm7.1 uses cm5 recovery which is unavailable in locked bootloader. So if you need to update you will have to re unlock and then relock again....
An unlocked bootloader is required for the full functionality of cm7.1, but weather it is needed to function on a day to day basis I am unsure..
ps, why did you need to relock your bootloader? My guess is you simunlocked via a different method than setool and it crashed your radio.
There is hope (If you want to beleive) if you follow this thread, but beware..there have been false claims before..
Please check this.

[Q] How to Lock Bootloader After Unlocking Bootloader

I have this PadFone S for over a week, and it's my 5th android device, but certainly the 1st one having a locked bootloader. So far I have read how to flash stock firmware, how to root and unroot, which requires unlocking bootloader first using CrowLock, how to install CWM and CM12 etc. I haven't try anything yet (still uprooted, and my bootloader is still unlocked).
One question still unanswered, is there any way to lock the bootloader after it's unlocked ? Perhaps by using the CrowLock app, or simply flashing stock firmware ? I need to be assured that any changes I do is reversible.
Thanks in advance
I too purchased the Padfone S and have the same question. Also, does anyone know if flashing crowlock will void the warranty of the phone? Can someone who has unlocked their bootloader using crowlock paste the output of "fastboot oem device-info"?
Does Asus' bootloader not check the signature for the recovery partition before booting from recovery? Given that everyone is flashing the recovery after rooting and running crowlock from the recovery, it seems so, but I'm not sure.
Anyone know if the bootloader's source code is available? I know it's based on the littlekernel, but I'm not sure which version it was built from.
Bump! I need the answer too.

how to unlock bootloader

hello devs and members
i want to unlock bootloader of my d6503
how to do that
should i need to backup something?
before unlock bootloader
and bootloader unlocking is safe and to install roms like cm
Just follow original Sony guide. It may be a bit confusing for the first time but everything is described there.
Also before unlocking bootloader you may want to backup your TA partition. Just Google how to do it.
And yes, if you unlock your bootloader then you can install every rom.
I think there are guides on how to do what you want...
But make sure to backup EVERYTHING BEFORE you start the unlocking process.
Thank you sir for information
Unlocking bootloader is safe?
Unlocking your bootloader is perfectly safe, just make sure to backup everything since your phone(not your SD card though) will get wiped
thank you sir I backup my ta partition then I unlock bootloader. and now I'm using resremix latest version
Any way of unlocking the bootloader when the service menu says it can't be unlocked?

Choosing a good plan to migrate to CyanogenMod

Hi people,
I just bought a new Redmi note 3, and I would like to pass him into cyanogenmod.
Here what i'm attending to do.
Safe the stock room
unlock the bootloader (unofficialy)
root the phone
install the CyanogenMod
1 : For doing the backup I was there are many versions of TWRP.. so which one use ?
2: I don't want to wait half month or even more just the unlock the bootloader ! so i guess I will go unofficially any good link
# I just saw that topic apparently it's possible to flash the TWRP without unlocking the bootloader.. is that method is compatible to put CyanogenMod after ?
3: Any good method, link will be welcome
Thank folks.
1. Alka twrp can backup the most partitions
2. Backup request will be accepted within hours lately.. but yeah that method is possible
Have to agree with that. Officially unlocking bootloader is a mostly painless process nowadays.It's quite possible to unlock your bl officially in less than a week. Since it looks like you know what you're talking about, I'm sure I don't need to tell you the possible benefits of having an offically unlocked bl over the unoffically unlocked one.
Personally, I think the best method is as follows:
Unlock bl officially
flash twrp through fastboot
flash twrp Alka
backup all partitions into sd card
flash appropriate cm firmware
flash rom, gapps, etc
flash apollo sound mod(cause it's great)
Please feel free to disagree.
Ivanlai I don't know If I will still unlock the Bootloader -> New method to flash Twrp recovery !! without unlock bootloader ! (kate/kenzo) safe ! by supercowz

[ADVICE] Unlock before N update!

Cleaning this up and clarifying as my original post was vague:
It is recommended that you unlock your bootloader before the 7.0 Nougat update. Although it will still be possible the process will be more difficult and risky afterwards.as you will need to use one of the edl mode tools (axon7backup, axom7tool).
The easiest way is to download this kit f you have the A2017U: (I can't speak to other models) (This kit and instructions are thanks to @jcadduono)
https://build.nethunter.com/misc/axon7/AXON7-A2017U-BL-UNLOCK-KIT.zip
https://build.nethunter.com/misc/axon7/INSTRUCTIONS.txt
The basic steps, which the above zip with take you through in detail are:
1. Flash Official B20 , enable OEM UNLOCKING after flashing.
2. Flash BLFastboot zip provided by ZTE when they had unlock method.
3. Enable OEM UNLOCKING in Developers Option
4. Boot to Bootloader
5. type : fastboot oem unlock
6. Done
Note: If you do not have the OEM UNLOCKING flag set in developer options you will get a soft brick. Also bear in mid this will wipe data.
All that being said I've heard Nougat to is going to be great from those in the know. In their words ”Well worth the wait! Hang in there!” from a HIGHLY credible source.
Why would anyone relock before update? I do agree anyone who wants to unlock should do it now.

For anyone looking to bootloader unlock, I've heard that the methods might change when the N update rolls out. It's a major update and although I personally don't have N and can't get a direct answer because those who know for sure are under NDA. I can tell you that the advice given to me is to not re-lock. So if you are thinking of unlocking your bootloader I'd do it soon while the methods are stable. Google confirmed that daydream is certified in an upcoming update so the daydream version of the stock ROM has been through googles QA. Might as well get ready now, we will probably have another surge of custom ROMS shortly after. I'm just sharing what I think is a best practice.

OK, so just to make it quick, for everyone, unlock your bootloader sooner than later. It is safe since you can revert it to a locked state at any time later.

I do it on occasion to test things I'm working on. Better to warn people who might do it to get PoGo or SafetyNet working I figured.

No need to bootloader lock an Axon 7 to get SafetyNet (Android Pay, PoGo, etc). Just do it the XDA way. But never relock!!!!
Could one of you guys explain whats so dangerous about relocking bootloader since u seem to know something I don't.
I have unlocked and relocked my bootloader several times by fastboot oem lock and restoring my stock fbop partition.
Have I done something wrong?

Read the OP.
I think what the op is trying to say is that by unlocking the bootloader you won't get ota updates. You would need to wait until a twrp flashable update is out or a rom running Android 7.

That's how it's been since modifying the bootloader was a thing. Unlocked bootloader = no OTA.

@stevecaboose
Unlocking Bootloader = Yes to OTA's.
Modding System and Boot = NO OTA's
hope that clear things up.
Close enough lol!
To be clear, it would be best to unlock before N is pushed out. I have it on good authority that unlocking your bootloader after you update to N will be more difficult and risky. Relocking would put you in the same situation. It's trivial to return to stock system+boot with an unlocked bootloader and TWRP and then the OTA will come through just fine. Or you can just wait for the TWRP flashable N stock ROM.
So to be clear, since I'm not 100% sure what affects the "system" and "boot" areas: I can unlock my BL using only guide 2 in this link ( https://forum.xda-developers.com/axon-7/how-to/guide-install-twrp-unlock-bl-flash-t3517379 ) and still get OTAs? If I install TWRP does that make me OTA-ineligible?

TWRP/BL unlock doesn't affect OTA, ROOT does.

You're totally wrong there,
TWRP will affect OTA's if the OTA need to check/patch recovery, BUT been Bootloader Unlock will NOT effect OTA.
To manage a clean/successful OTA's installation, you need to be FULL STOCK. (System, boot, Recovery, aboot if the OTA need to patched).
I think the OP was trying to say that it's possible current tools will not work to unlock the bootloader after the 7.x ota is installed.

I'm not fully agreed with that. You can install OTA's when you receive it, download it, install it when first booted into twrp cache. Only if you're not rooted. When you're rooted first unroot and in principle this should work.
There are several cases on internet about that. Even I did it with an unrooted but TWRP-ed Zopo C2. Received an OTA and installed it.
Im always glad to learn but IMO there are some possibilities to do the ota after all. But I am willing to accept it's a general fact that twrp could affect the normal OTA.
Edit : let's wait and see when B10 is rolling out and if I get a notification about that and if I can install it as a normal OTA(not with SD) with TWRP. Keep you updated:cyclops:
Noob here, forgive me ...
So what is the best way to only unlock bootloader without flash twrp?
A2017U, B29.
Thanks

1- Download Official B20 from ZTE SITE (look Software Updates for the 6gb variant)
2- look in the forum for the B20fastboot zip file
3- Move both files to your SDCARD.
4- Enable OEM Unlocking under Developers Option
5- boot to stock recovery.
6- Install B20 official update via SDCARD (this will wipe Data)
7- boot and re-enable OEM Unlocking
8- boot to recovery and install B20fastboot zip
9- boot to Bootloader and Unlock bootloader using this command.
Code:
fastboot oem unlock
If I remember correctly will reboot and factory reset the device , you'll need to re-enable OEM UNLOCKING and boot to Bootloader to flash TWRP 3.0.3 USING fastboot commands
