[Guide] Safely unlock bootloader on official MM

UPDATE: This is now unneeded because threr is a faster way ro unlock bootloader on official MM here, he updated for official MM
Hi, I discovered an unlock method for official MM!! This maybe long but's it totally safe
You need:
Adb and fastboot environment ready PC
LP RAW File
Android 6.0 Beta Unlock tool
Android 5.0 One-Click Unlock tool
First version of beta MM (Z00A) (Z008)
Official MM zip (find it on Asus site)
Thanks to all people upload these links
Just do the following:
Flash the lastest LP via AFT (using raw file given above), wipe all data. If you already on MM, you have to downgrade
Unlock your bootloader using 1 click tool given above
Boot to stock recovery and sideload the first version of beta MM
Unlock the bootloader using MM beta unlock tool above
Boot to stock recovery
Two case here:
Case 1: You can't boot stock recovery
Normally boot your phone (to Android)
Setup it as a new phone
If it shows there is a new firmware, don't update!!!
Enable Developer options, then enable usb debugging
Copy the official MM zip to external sd card
Open command prompt, run adb reboot recovery, accept the adb permission if prompted
After it boots to recovery, select Apply update from SD, then choose the zip file you've copied before
Wait for it to update, it may stuck at flashing splashcreen, don't worry, it's trolling you, may be Asus forgot to update the script
Goto step 7
Case 2: You can boot stock recovery
Sideload the official MM zip (adb sideload <filename>.zip)
Goto step 7
7. Flash this TWRP (fastboot flash recovery <twrp>.img)
8. Root your phone using this method
9. Reboot, if it shows "Your phone has failed verification bla bla..", then you've success. It may reset loop like note 7 in the first time start, don't worry.
9. Enjoy :highfive:
Note: If you're facing with battery problems on MM, factory reset it in Settings > Backup and Reset > Factory Reset > Erase everything
Successfully on my ZE550ML
The warning screen is normal so don't worry and there is no way to fix it for now

Yes, BL will be relocked once you upgrade to MM.
If you want to unlock MM BL(6.0), refer to this thread.
Or you can downgrade to Lollipop referring to this thread. Then your BL(5.0) is unlocked.

Upgrade to MM
Hello folks!
2 week before MM was released i'ved opted to unlock my ZE551ML BL and therefore install twrp and a MM custom ROM..
so here´s the thing i stayed with the ROM for about 3 weeks and honestly..it works very well..but when i knew that 6.0 official was coming out i decided to go back to stock..i did it following manny tuturials avaliable for me to get my BL Re-Locked..but unsuccessfully..so i followed mr_gourav2000 tuturial (http://forum.xda-developers.com/zenfone2/development/stock-rom-ul-z00a-ww-2-20-40-168-t3354526) and reverted to the WW_Z00A-2.20.40.183-to-2.20.40.184 (hopefully i can get the sshot in this post) version...since my BL is unlocked i can´t get no updates..my question is:
Is there anyway to go to MM 6.0 by ASUS with the current status of my phone?
is there anything i can do to revert this??
Cheers to everyone

Have you downloaded the correct build? There are build for MM bootloader, if you flash the normal builds, it will fail and reboot to recovery again. Gapps is the same for all builds
After you install that special build, do not update to newer nightlies, it will fail. For updates, check the link i give you and see if there is a new MMBL build.
About that, here is the post: http://forum.xda-developers.com/showpost.php?p=68542370&postcount=8551

hello friend, I tried to install the CM13 ROM that indicated me and I get Error 7 in TWRP 3.0.2.0, I have Android 6.0 (.134) official and if I can change kernel and flash rom SuperSU but change with a new MM Blows I can not (CM13, AICP, beanstalk ....) thanks for your help!

Run the script again (i gave you in above post). Download the CM13 in that link, not in the OP of CM13 thread. Flash that CM13 and Gapps (Gapps is universal for MMBL and LPBL).
May be you have corrupt download, I'm currently running CM13 on MMBL

Hello, I have finally found the solution, the problem is the recovery, the TWRP 3.0.0.2 da failure with new builds, I Flashed next on the link you put me through adb and now it works, thank you very much for everything .

Guide to switch from Vendor ROM to EU ROM

This is for people who have received their phone with a pre-installed Vendor ROM (MIUI Global Stable 8.0.8.0) and wants to switch to the Unofficial EU ROM. In my opinion, the EU ROM is currently the best ROM without any Chinese bloatware or popups until Xiaomi decides to release an actual Global ROM.
For those who are already on a China Stable ROM, there is already an excellent guide to install TWRP, ROOT, compiled by @underlines. This is only intended for switching from a Vendor ROM as I wasn't able to switch from a Vendor ROM to an official build using the previous guide. You need to be on an official build to be able to use TWRP and flash the EU ROM.
EDIT : The reason why I have mentioned to flash an official build at first is because, TWRP can be unresponsive with some Vendor ROMS. You'll be able to boot TWRP but touch would be frozen. I've tried with both versions of TWRP and it wouldn't work with the Vendor ROM installed on my device. TWRP over the Vendor ROM may work for some users.. For some builds like the one which came installed on my phone, it may not work. If TWRP works for you without being on an official build, you can skip the part where you have to flash an official ROM.
1. You need to have an unlocked bootloader. Please follow instructions on the other guide on how to do this.
2. You need the older version of MiFlash found on this link. Thanks to @Thorin78 for this link.
3. Download and extract fastboot Stable or Dev ROM and extract ROM folder to the C:\ Drive. This is because MiFlash may show a "cannot find file" error if you have a lot of subfolders. To avoid this, its best if the folder is C:\ROM Folder.
4.In the older version of MiFlash, click advanced and change the fastboot script location to the flash_all.bat in your unzipped rom folder.
5.Connect your phone in fastboot mode, click "Refresh" in MiFlash. Once your phone is detected, click "Flash" and it should now successfully flash the official ROM of your choice.
If you wish to be on a Xiaomi Official Stable or Dev ROM, Stop here! If you wish to continue installing the EU ROM proceed with the steps below.
6. Now that you have successfully flashed Official Stable or Dev ROM, use Minimal ADB and flash TWRP RC2 using the instructions in the other guide.
7. Once you are in TWRP, Swipe right to allow System Modifications and copy the forced encryption disabler using MTP. Flash this file to ensure that there are no bootloops.
8. After this step, go to WIPE, Format Storage, type "yes" and then Reboot Recovery. Copy SuperSU and EU ROM to storage and flash. Phone may take a few minutes to boot up and you will successfully boot the EU ROM.
For everything else, please follow the guide posted by underlines.
TWRP EU RC2 works with the China Dev ROM as well. Once you Swipe to Right to allow modifications, don't forget to flash the latest dm-verity and forced encryption disabler script from here. This is to prevent the device going into a bootloop.
These are the steps I followed and I am on EU ROM. Hope this helps people who wish to switch to the EU ROM from the Vendor ROM.

I managed to flash with latest miflash using your guide my bootloader was already unlocked check using:
boot your phone into fastboot and COMMAND PROMPT " fastboot oem device-info "
most are probably unlocked with vendor rom but not all.
Don't try to unlock with this method just check to save sometime.

I guess it also depends on the Vendor ROM and customization which comes installed on your device. Not all Vendor ROMs for this device are the same. I tried everything under the sun with the latest miflash. It would detect device and even give a "success" output but the ROM was never actually flashed. The phone would still be on the Vendor ROM. Its as if some Vendor ROMs have some form of write protection baked in.
I could only get it working with the older miflash.

I'm not saying it was easy, the hard thing was making the unpack ING of the file. Sort of did it twice never had that problem before.

This for people who don't want TWRP, root and dm-verify, just genuine Xiaomi rom with OTA updates and remove vendor rom.

QQ.
I did the following on my Mix and wondering if I am missing anything. I should say that everything "appears" to be working perfectly on the EU rom.
My Mix came with 8.0.8.0 Global (Vendor ROM) and I wanted to move onto the Xiaomi.eu rom. I loosely followed the above guide and did the following steps:
Applied for Unlock
Unlocked the device via MiUnlock
Used Minimal ADB and booted the device into FastBoot
Confirmed device was Bootloader unlocked
Flashed TWRP (latest non-eu build)
Booted to recovery
DID NOT swipe to edit system partition, left that read only
Flashed the latest Weekly Xiaomi.eu build
Wiped Dalvik/Cache
Booted phone
Performed a Factory reset.
All seemed a little too easy and I didnt need to go to an "Official" china ROM first. But I do have a few questions...
Should I have swiped Yes to enter Read/Write mode for the system partition and run a dm-verify? (I am not interested in Rooting the device at this stage)
Should I have performed a System clear in TWRP before installing Xiaomi.eu ontop of the Vendor ROM?

Wouldn't worry about it the vendor ROMs aren't poison, not sure about dm-verify if you kept read only. I would of swiped then flashed dm-verify but didn't mean I know what I'm doing.

This is because some Vendor ROMS have some compatibility issues with TWRP. Touch screen wouldn't work on TWRP. I tried both TWRP versions and couldn't get touch to work.
Finally, I flashed the China Dev ROM and then used TWRP RC2 and touch functionality worked.
As some users below have pointed out that they could get to EU without flashing the one of the official builds, I guess it depends on the amount or type of vendor customizations applied on your device.

Which version do you own? I was wondering if this would work with the 6GB as well.

This works with both versions. The ROM is compatible with both variants as the size of memory and storage doesn't affect compatibility.
I have the 6\256 variant.

Thank you. It worked. I fastboot twrp then factory reset the device and flashed the eu rom. All good. My bootloader was unlocked by the vendor.

Can someone please give me some advice? Just got the phone a couple hours ago. I took a picture of the info page. Based on the screenshot am I on the vendor ROM or official? I'm thinking I'm on Vendor because it has GAPPS already included.
If I'm on Vendor ROM and want to get to rooted EU Rom I can follow directions in the OP right?
How do I know is if my bootloader is already unlocked? Many thanks

Vendor (there is no Global ROM for Mix). You should unlock your bootloader (check if it's already unlocked using "fastboot oem device-info"), flash TWRP, wipe and flash EU

Still No VoLTE for Redmi2 8gb variant

Hello, I currently am using a jio sim as my primary sim. However, i tried all the methods suggested on xda but still no volte.
List of things that i have tried:-
1. Tried flashing the modem(doesn't work at all)
2. Flashing MIUI 7.5 version as suggested( V7.5.2.0.LHJMIDE_20160629.0000.25_5.1_global ) to be precise
3. Tried flashing another one of Redmi2 Prime's firmware(global developer rom)
4. And tried flashing several other ROMs(Orion OS, RR, Tesla, AOSP and DU) after doing step2 and still no volte support found
Can anybody help me?

@cypherx1998 Flash kitkat dev rom 7.1.5 or newer from fastboot, after it starts booting turn of your device and boot into fastboot, then flash the latest lollipop dev rom and boot into it, setup your device, then go to settings, mobile data (I think, it's where you have the option to change to 3g and 4g data) and enable VoLTE voice calls, after that, reboot into fastboot and flash TWRP 3.0.2-0, then go to wipe, advanced wipe, select:
cache/dalvik-cache
system
data
internal storage
and then wipe, after that go to wipe again, select cache, then "change partition format" select F2FS, and swipe to apply, do the same thing for data, don't do on dalvik-cache and system, or else this may brick your device.
Then flash the wt88047 firmware avaliable on LineageOS second or third post, do a full wipe again, install VoLTE universal Patch Here do a full wipe again, then flash the latest LineageOS build, after wipe only cache and data, flash OpenGapps pico arm android 7.1.1 and reboot.
You will have VoLTE

However ur device will start lagging and ur free ram won't go higher than 300 MB.

Took me time to try this...but didnt work.....you might think that i didnt follow the steps properly..but i did and i verified on each step that i was doing it the right way....but sadly it didnt work

You may try Redmi 2 Prime ROM (stable or dev) for some days..Check whether you get VoLTE on that ROM or not.. If yes then use that for some days maybe 2 or 3 days..It will be slow at first then after 2 to 3 hours of use u will feel no lag..I was using Developer version for 2-3 months which was fine for daily driver..I just faced storage issue..Then I tried stable version, and the same issue was there.. So I decided to use some custom ROMs and I Flashed AOSP Extended (Nougat)..VoLTE works fine and the ROM is so much smooth with good battery backup..But due to slow internet speed I am using Mokee 7.1 right now.. You can try using R2P ROM for some days...If VoLTE works there then it will work on other ROMs too( as per my experience).
Ignore my english...

Yes just flash either the dev or stable Redmi 2 Prime ROM. I can say that this works because I have flashed it on as many as three devices. Just go to this link and find out Redmi 2 Prime Global Developer ROM or Global Stable ROM.
http://en.miui.com/a-234.html
Remember these are to be flashed in fastboot. After flashing this, you can flash any Nougat based ROM like LOS, RR, AEX, cRDroid, etc to enjoy VoLTE on those ROMs too.

1)download Mi flash tool
http://en.miui.com/forum.php?mod=attachment&aid=NzYzMjQzfGFlZDEyMDMzfDE0NzI1NDg5MDJ8ODE5MTF8MzM2MTg0
2)
download fastboot rom redmi 2 prime global stable or china
http://bigota.d.miui.com/V8.1.3.0.L...DI_20161230.0000.00_5.1_global_23ac47dab8.tgz
above is global stable link.
3) put your phone in fastboot mode, unzip the downloaded rom. (avoid spaces in between folder path/name eg "C:\New Folder\Extracted rom\...." is not allowed instead it should be like C:\New_Folder\Extracted_rom\.......)
4) open mi flashing tool see if your device is listed. refresh to see. select clean all (flash_all.bat) option from bottom of mi flashing tool.
5) click on flash, and let it boot.
you would be able to use VoLTE now in miui rom. if you want to change to any N based roms just flash twrp and clean install any rom.

Flashing the MIUI 7.5.2 global ROM should work. Wipe everything and do a clean install. Once you see an indication of VOLTE on the MIUI then you should be able to get the same in other ROMS. I just did it recently.

Flash the redmi 2 prime rom using any of the methods fast boot or normal. If VoLte is what u r looking for

I think i can help you dude. Flash this fastboot rom you have. Boot it with YOUR Jio sim in the first sim slot inside. Setup everything normally in the phone. After it booted, you WILL see the Volte symbol in the statusbar.
Now root it and install TWRP. Now install a Volte rom of your choice. It has to work.
I will say you why this has to work. I own this device. The 8GB variant. My friend owns the same device. While my device had Volte working, his' didn't work. I checked it. He had kitkat bootloader. Then i flashed the lollipop stock rom in his device in fastboot mode. i directly rooted the device and installed cm14.1 in his device. Still no Volte. I wondered what the fcuk was just happening. My friend was like i'll cope up with this dude. I'll use jio 4g voice. But couldn't leave it like that. I tried it the second time just like i have told you and then VOLTE STARTED ****ING WORKING MAN !!! I was on cloudnine !!! Just helping you out !!
I think the reason Volte was not working is because the jio sim needed the stock rom to trigger it to start Volte sevices. Before it, the jio must have thought "yeah, this is a non volte device ". Just saying !!
Have a nice day !!!

How do you check what bootloader you're on currently?

I think their is no(simple) way to know that.But you can try a app named "phone info". But it didn't work out for me.It is showing unknown bootloader.
The best way to know your bootloader version is " try to remember which miui ROM u flashed last".
Or there is lolypop firmware in lineage is thread for u.

Simple. Press vol down and power. will boot into fastboot mode.
If the letters saying FASTBOOT are in green color and small, it is in KitKat bootloader. If the letters saying FASTBOOT are in Blue color and little big, it is Lollipop. I know it sounds a little lame, but trust me, this is a reliable method. If you flashed the lollipop rom via the mi Flash application through system, and youve got the blue colored bootloader, then you are on lollipop bootloader

[GUIDE][MOD]Move to MIUI from any custom rom through TWRP

First of all, backup your EFS.
Once done, proceed to the process.
1.Download the files below. Download the MIUI rom you want to flash and get it on your device.
2.Go to recovery. Wipe cache,dalvik cache,system and data.
3. Install the rom along with lazyflasher(link below).
Voila! You flashed it but unfortunately when you reboot it, it will vibrate once and turn off. Being in this state you can't go back to recovery too. So lets fix it.
4. Extract the RN3_unlockblonly and fastboot_edl on your pc.
5.Connect the device to pc and click on edl.cmd from the fastboot _edl.7z. Tge device screen will become black. Let it be.
6.Open Miflash tool and select RN3_unlock_only. Refresh. And then click on flash. Once done remove the device and go to recovery. Wipe cache and dalvik cache and done.
Happy MIUIing!

What error do you get?
You must flash latest miui fastboot rom, if you are still on LP bootloader.
I can flash now migrate between miui and N custom roms without problem with ZCX 0917
But thank you anyway

Why not flash xiaomi.eu rom? That won't lock your bootloader and twrp remains.

Even official global/china dev/stable doesnt lock BL, if you are already on MM bootloader.
+ From my experience those official roms are better compared to .eu or multirom

If you ever flashed MM fastboot miui on this device before, then yes. If you didnt you are still on LP bootloader, which will result in BL relock and you will have to boot to fastboot and then unlock it officialy via miunlock.
Ptocedure in twrp:
Format data (type yes)
Advanced wipe (wipe everyhing, except microSD)
Flash Recovery miui ROM, reboot:good:

No, still I haven't flashed MM Fastboot Rom. I've checked Bootloader version in CPU-Z App but it says Bootloader - Unknown!
& Is it necessary to wipe Internal storage, bcz I don't want to remove all that my stuff!?
You told me that procedure it's for Reverting to MIUI right?

I think its neccesary to wipe data aswell...do a backup on microSD...
You will lock your BL if you flash official rom...so you will have to unlock it via fatbooot.

How to Go back to MIUI 10 From MIUI 11 ?

For some reason I didnt like the MIUI 11... and have some bugs also.. i like the miui 10... can anyone help me how to downgrade to miui 10 (10.3.6.0) ROM... any help will b greatly appreciated.
do i need to unlock Bootloader to downgrade ?
Can i downgrade to miui 10 via copying the MIUI 10 ROM in root directory of internal storage and flash it via setting>about phone?system update> select the rom zip and update ?

I would also like to downgrade back from Miui 11 to Miui 10 as it is far too buggy, random lockups, phone heats up/drains fast and needs rebooting every few days to fix, VoLTE no longer works on 2nd SIM.
I can't seem to download the Miui 10 latest stable ROM from en.miui.com as it only shows link for Miui 11 for my phone, can anyone help with the latest stable miui 10 download link?

MI9T has anti-rollback enabled, which means either you have to use Mi Flash, edit scripts inside .tar (stock firmware meant to be flashed through fastboot) and flash it, or unlock bootloader, flash twrp and install MIUI 10 zip.

How do you do that for Mi 9T?
How do you do any of what you said? I have mi 9T also like previous dude off xiaomi site my phone only has 11 to install as a room? Not 10..
