when do i need an unlocked bootloader & flashing methodes

[email protected]
i'm little bit confused about unlocking the bootloader on an mi5 device. I read somewhere that it's not needed if you use the updater app on the phone. i think this is only true for official rom's which came from en.miui.com it self?
can i use the updater app if i want to install the official en.miui.com 8 global rom without unlocking the bootloader?
if i want to install an xiaomi.eu rom, i will have to unlock the bootloader first?
does root on an official rom need an unlocked bootloader too?
there are more then one way to flash an rom on an mi5 device, updater app, fastboot and miflash tool, twrp(which is not preinstalled i mean?). but i read something about an edl mode, but cant find out what this does mean? is this maybe the fastboot and miflash tool mode?
many thanks!
best regards

Hello there,
what ROM are you running currently? Broadly speaking, you have 2 tools to change the ROM on Your device: the updater app and Fastboot (miflash uses fastboot too, and twrp requires fastboot to be installed). The updater app allows you only to upgrade your current ROM to the newest version. Fastboot (and the related tools) allow you to change ROM completely (e.g. switching from China Stable to China Dev or from China Stable to Global Stable or from China Stable to miui.eu Stable), and will also allow you to root your device through TWRP. To use fastboot, however, you will need to unlock Your bootloader.
Regarding EDL mode, it is the Miui stock recovery mode, which can be used together with the Xiaomi desktop application to flash new ROMs. It is not a widely used method, because the desktop app is quite buggy.

hello
many thanks for your replay.. i'm currently on miui 8, the global alpha version, so i already do an flash.. your answer is toop, again thanks for that!! but there are some new questions, edl is the miui stock recovery mode, does this mean the recovery as i know it already in a form from recovery.img? if i also want root i will have to flash twrp, this would then mean that the miui stock recovery (edl) wouldn't work anymore? so if i want to go back to an official global rom, do i need to flash the stock miui recovery first? the way to do that would be through fastboot? where can i get the stock miui recovery?
have an nice day!

Can I install MIUI ROMs trough TWRP like any other ROM?

I just get the Mi5 and like I said in other se treads, im kind desapointed with the MIUI mostly because the touchscreen, performance and the notifications bar. I realy into adveture myself in the world of the custom ROMs, like CM 14.1, but my doubt is.. Can I only go back to complete Stock by flashing MIUI by Fastboot or can be installed trough TWRP like any other ROM?

official MIUI - use MI flashtool via fastboot method only
unofficial MIUI - flash via TWRP recovery or MI flashtool will also work

Sure you can. Actually I used twrp to update the stable version of miui for countless times. It is OK, at least for my 64G mi5

No. Official rom you must need miui flash tool.

you can flash Custom recovery form EDL mode even in bootloader locked

Hi. What would be the safest way to go back to global stable rom? I am on miui eu 6.11.10. Boot loader is unlocked, and my recovery is twrp 3.0.2.0. In recovery I get error message when I try to clear cache "can't mount cache". I just want to be able to receive ota, got tired of changing roms. Thanks

Hi I'm on eu Stable 8.1.6. I want to flash developer Global 7.1.19. What is the safest way? Can I do it by TWRP and what I should wipe?

Yes; if you do a backup via TWRP of your miUI rommed device: sysimage + data + boot
advice: save it outside of the device (your computer, etc) for storage.
Then you can go frolicking with wathever rom you want, when tired put back in the device the backup files; reboot in recovery and via TWRP do a restore.
advice 2: as a baseline for a good/solid backup save also "efs" (that is the modem/sim stuff).
Why sysimage and not system?
Because that is an image (all the bytes) and the other is just the bytes in use; so sysimage will be a larger (in mb/gb) file but a more robust one (backup wise).
...
and for the two who inserted their personal questions in this semi-old thread...

the rom download page with the official flashing guides: http://en.miui.com/download-299.html
Because to do what you ask you have the recovery method and the fastboot method.

Going from eu to global ROM by TWRP what should I wipe (data, system, dalvik, cashe...)?

I flashed global miui rom through twrp. Use this article:

Mi Mix 2 official global developer rom available

Official global rom is available for Xiaomi mi mix 2, even if it's not listed on the miui website yet.
This is the download link: http://bigota.d.miui.com/7.9.21/miui_MIMIX2Global_7.9.21_7f94ca393f_7.1.zip
This is the recovery version, fastboot version is not out yet, so there are only two ways to install it:
Method 1 (works on both locked and unlocked bootloaders):
- Download the rom on your pc
- Download and install my tool on your pc: www.xiaomitool.com/latest (read more about it here: https://forum.xda-developers.com/mi-5/how-to/tool-xiaomitool-xiaomi-rom-changing-easy-t3627081 )
- Plug your device to your pc, launch the tool and use it until you reach the rom selection view
- Select "show advanced options", then "Official Miui rom (.zip)" and then select the file of the rom you have downloaded before
- The tool will install it automatically
Method 2 (works only on unlocked bootloaders):
- Download the rom and supersu zip on your device
- Install twrp to your device
- Install the rom file through twrp
- Patch the rom by flashing supersu
PLEASE NOTICE: if you use this method dont update your device because this will soft brick it. You need to flash manually from twrp the rom and supersu if you want to do that. This method is for those who want to try the rom, not to keep for a long term. If you want to keep the rom, use method 1 or wait for fastboot rom.
FAQs:
Q: This link is official and how did you get it?
A: It's official (just look at the download url) and I have it by emulating an ota update call
Q: Have you tried installing it on your device?
A: I have not mi mix 2 so no
Q: This may brick my device?
A: It may brick it, I have not tried yet. This is to tell you to do on your own risk, I'm not responsible
Q: Why I have to flash SuperSU?
A: Official rom are not compatible with twrp natively, your device will not boot if you don't flash supersu.
Q: What is the difference with your tool?
A: My tool uses stock recovery to flash official roms, so there is no need to unlock bootloader to install twrp, neither to flash supersu
Q: This method(s) doesn't work!
A: Ok, sorry to hear that, leave your feedback. This methods are not tested yet with mi mix 2, so there is the chance they might not work. Just leave both positive and negative feedback about it.

Would you care to share the ota update call for those of us too lazy to use wireshark?

Should i continue?

i tried the tool with a locked bootloader but it says i cant flash it with a locked bootloader.

I have unlocked my bootloader.

Works for you ? And which option did you choose .. And did you do anything before ?

Didn't work for me, see my previous post

Hi vic20nl,
So you continued but had no luck ?
Or did you abandoned the flashing ?
If you decided not to proceed, I might say that installing a custom recovery is an easy thing.
And I cannot recommend too much to install such a custom ROM as it will allow a lot of things, especially to back-up before installing a new ROM or to install a custom ROM like Mokee or EPIC ROM.
Regards.

Heading has come up on the MIUI ROM download page for the Mi MIX 2 Global, so it should not be long for an official ROM

Yeah just noticed that. Shame it's still miui 8 not miui 9.
Maybe soon for miui 9 global.

Did somebody manage to flash the developer ROM (that is what is what mentioned in first post) as that is suppose to be MIUI 9?

Yes, I did. You need to use fastboot.

Hello Guys!
First at all, thank you @franztesca for your great work on the flashing tool and bring us early the Global Dev Rom for Mi MIX 2.
I would like to ask and/or bring in this discussion here an other aspect to flash the Global Dev.
First an unlocked bootloader is requiered. I used this method at another Xiaomi, the Xiaomi Mi 5.
I am actually on the Xiaomi.eu Rom and i would like to change to the Global Dev. My bootloader is open. I flashed the Xiaomi.eu Rom with TWRP, but i dont install TWRP, i just boot into TWRP by using the commend : "fastboot boot twrp.img", just booted not flashed! After the boot i flashed the Rom via ADB Sideload an performe a Data Rest befor.
In this case i am able to keep the original Recovery, but i could also have an Custom Rom.
Now i want to change my Rom again, to your brought Global DEV.
Iam loking and asking me, how could i flash it the easyest Way, without loosing any Data and of course without any Bootloops and with regular Updates for the future.
So i think you musst Add a Variant Number 3, please correct my if iam wrong, but for me it is the easyest way with an unlocked Bootloader.
1. Download Rom and TWRP
2. Set Mi MIX 2 in Fastboot Mode
3. Boot via Fastboot iside TWRP (fastboot boot twrp.img"
4. Flash the Rom an reboot
Now you have Global Rom with offical Recovery for futher upadates!
Greetz

Thanks, I cannot do it via the updater app from Xiaomi by coying the zip file to the device and then choose the package in the updater?

You can't go from the China ROM to the Global ROM via the updater app. You'll have to use fastboot/Mi Flash.

So if I get it right:
- Unlock your bootloader trough a Xiaomi website and wait for an sms.
- Use fastboot to flash the global rom. (Do I need to wipe before using the Mi tool to flash?)

I didn't have to go through getting permission, my account already had it from previous Xiaomi devices. If you haven't yet, then yeah wait to get permission.
Mi Flash gives you the option to relock the bootloader upon flashing or not. There is also an option to keep data, but I would advise not doing that when switching to the Global ROM.
Also, after getting permission to unlock your bootloader, if you relock it again, you can always use the Mi Unlock tool to unlock it as much as you want since you already got permission to do so. When I had the Mi5, I can't even count how many times I unlocked/relocked the bootloader.

Once re-locked can you use banking apps etc?

Wrong recovery
When I try with method 1, he tells me I got the wrong recovery. Bootloader is open ..

(flashing / booting) Problems with all roms

Hi,
since many days I have a new Mi8.
The device is a chineese model, and because it was delivered with unlocked bootloader and a shop ROM, i want to use the latest Xiaomi.eu stable rom.
After flashing the TWRP, i cleared all (System, Data, Cache, internal storage) and installes the latest xiaomi.eu ROM.
Unfortunately the ROM was notstartet. Later i readed, that the xiaomi.eu ROM needs the system partition, so i tried to install some different ROMs.
All tested roms failed to install (device missmatch), so i tried to use different recoveries and at least i updated the vendor Image to MI8Global_V10.3.5.0.PEAMIXM.
After this, some Roms are able to install, mut the ROMs wont boot.
After a clean install of the xiomi global fastboot image, the phone is running, but i still have problems to install custom ROMs or the stable Xiaomi.eu ROM.
The fastboot ROM installation with mi flash tools ends with an error (Not catch checkpoint (\fastboot -s .*lock) Flash is not done (I choosed the option clean all, not the lock function)
cDroid Rom is working, but with this ROM i cant use google pay.
cDroid with update to xiaomi.eu weekly is also working, but also without google pay.
Xiaomi.eu stable - bootloops
Do you have any ideas why i cant use all ROMs?
Should i choose a chineesevendor image or something else?
I also heared, that it could be, that the device bricks, when i try to re-lock the bootloader, is this an option?
Which ROM should work fith functional google pay ?
Thanks in advance

The problem seems to be solved,
i have to flash "Disable_Dm-Verity_ForceEncrypt" after the flashing of every ROM, then I have no bootloops / boot Problems.
Now i only have the problem with google pay...

I couldn't also get Miui Eu bootable on my mi8 last time. I didn't realize what you had mentioned Disable_Dm-Verity_ForceEncrypt. But I could manage to get MiRoom Miui workable and it seems ok for now.

DM verity zip removes the 'DM Verity' check that looks for modifications to the boot partitions (D-device M-mapper). You cannot boot with modifications (like root) without disabling the verity check. Also, if you are on a stock ROM, your custom recovery image file will be overwritten with stock upon reboot if you don't disable DM Verity. Hope this helps you understand more.
Found it on this topic.
I´m still looking for a ROM with google pay support, but iu think with unlocked bootloader and without root therre is no chance...

Question Downgrading from stock A12 to Xiaomi EU A11

I'm planning to go from stock 13.0.2 A12 to Xiaomi EU 13.0.10 A11. Based on what I read, this is what I have to do:
- Unlock bootloader (which will factory reset the phone).
- Start fastboot mode.
- Connect to PC.
- Download the ROM (Recovery for RN11, since it's downgrade I'll have to factory reset but it'll already be done during bootloader unlock)
- Run first_time_installation.bat (or something like that).
Are these steps correct? This will be the first time I flash a ROM and I really don't want to mess it up. Thanks in advance!

The first step is correct, you must unlock the booloader. However, you can't install Xiaomi.eu ROM on fastboot mode, that's only for stock ROMs. If you try to do that using a custom ROM, it could brick your phone. For Xiaomi.eu (or any other custom ROM) you need to install first a custom recovery like TWRP: first downlaod the custom recovery file, then copy it into the storage and then install it. You can do the last 2 things with CMD commands . Then copy the custom ROM file like any other file into the phone's storage, restart the phone on recovery mode and install the ROM from the TWRP interface. I did it like a month ago, I don't remember all the details though. Just look for a tutorial, it's not that hard.
Good luck.

Haha thanks for your reply! This came a bit late, it has been exactly a month since I flashed but I hope this could help someone else. Spes/spesn is listed as recovery on the list but the Android 11 versions only come in Fastboot. When I unlocked bootloader, I had already prepared Pixel Experience and Xiaomi.eu ROM. PE's recovery gave me bootloop so I used the next thing available and flashed Xiaomi.eu .bat file.
I was a bit worried when it was stuck on the same screen for 15 minutes but then it loaded with no problem. Not really sure if I did the right thing or I was just lucky
