Impossible to unlock bootloader and install TWRP - Xiaomi Mi Mix 2 Questions & Answers

Impossible to unlock bootloader and install TWRP - Xiaomi Mi Mix 2 Questions & Answers

Hello everybody, I'm new to the forum. I would like to expose you to my problem with the hope that someone can help me and solve it. In May, buying a XIAOMI MI MIX 2, (I am the first ownwr), no brand. After a few days of testing I consider myself quite satisfied with regards to performance except for the photographic sector, so I decide to install the TWRP following the procedure that first obliges to unlock the bootloader to install it, I follow step by step the XIAOMI guide but at a certain point tells me that the number for which I requested the release is associated with another account, I try and try again unnecessarily, all useless. Among other things, I do not know how to disable the account used for registration on the XIAOMI suto. Contact also XIAOMI but nothing, no answer. I need the unlocked phone to be able, tomorrow, to have root permissions and anything else. I thank in advance those who will give me suggestions to come to terms with it.

Let me be the first to ask a complete noob question.
I bought a Mi5s a couple of months ago and loved the phone. However, Miui 8 is becoming somewhat of a annoyance for me. I flsahed the global ROM by making an EDL cable, pretty straight forward. But i'm still missing the stock android experience I had with my nexus 5. Today I saw that Lineage OS is being developed for the Mi5s and when this becomes more stable I really would like to try it.
My question is, where do I get started.
I know ik need to request to unlock my bootloader (I did a couple of days ago) and that I then need to somehow install TWRP. But thats it. Is there a manual I can use or at least read to better understand how the process works and what I need to do?
Thank you very much
p.s. I read a lot of stuff about the mi5 and how to flash it but i'm wondering if the process is the same since the Lineage OS 14.1 is ported and unofficial.

Noob question here too, loving the phone, battery life is amazing after samsung s4 lol.
I read on i guess xiaomi.eu forums not to wipe system partition on twrp. I was always wiping system ( i was just leaving sd and internal and wipe anything else.) So, i shouldn't wipe system on mi5s?

Hi
First of all, I agree totally that MiUi gets a crappy feel after you get used to it and start missing the old vanilla Android. Also, yes. You need to send an unlock request for unlocking your device. Refer to an unlock thread or wait if there's no thread yet. Somebody will eventually make a thread regarding this unlocking and flashing TWRP thingy (mostly me). And unlocking ain't gonna void your warranty, so all good. I don't think that Unlocking the BL is the hard part. You've just gotta apply for permission on their site with a good reason why you wanna unlock it and all. Flashing TWRP and rooting- here comes the fishy part. You can't just flash any TWRP on any device (unless you are that stupid). So wait till a proper thread has been posted about this topic. I would suggest you to go ahead and unlock the device. And also, no question is a noob question. I just named the thread like this so it sounds better. XDA is an open community built with the sole purpose of helping techy-brains all over the world.

Thanks for your reply. I got my unlocking permissions but when I try to unlock with the unlocking tool I get an error that the mi phone isn't connected. On the Miui forum I read a couple of different ways to unlock the device. One of 'm stated you can unlock it on Globa Stable but you have to enter your Mi account details under developer options/MuInlock. And if you can't find that option you have to use a developer rom. Problem is, there is no Global developer rom that is newer than the global. Can you help me?

All that about flashing developer ROM for unlocking is plain bull****. I unlocked mine on global stable 8.0.6.0 (my redmi note 3). If you have been getting errors unlocking the device, make sure you are following these steps correctly:
1. Update your Mi adb drivers.
2. Enable developer options in your phone, enable OEM Unlocking and USB Debugging (because 60% of people forget this step).
3. If you've got permission officially, wait for a week or so, because it needs time to get our name and Mi Account ID registered on their servers as they get up to hundreds of unlock requests per day.
4. After a week has passed, connect your phone to the PC and start the unlock tool. This time it will get unlocked successfully. I guarantee you that this method will work if you follow it exactly how I told you to. I have tested it myself and trust me, it works!
Do update me on what happens with your device. Best of Luck! May the servers be with you... LOL! :laugh:

It worked!! The server's were strong ? It was a driver or device issue. I tried it on another laptop and it worked instantly. Thank you for your time and effort. On to the next step.
P.s. strange thing is I never received a text messages from Xiaomi that I could unlock but when logging in to the unlocking tool the check said my account had permissions to unlock. Whatever, it worked right.

MY xiaomi mi5s

Mi5s focus
So I have Mi5s , from gearbest, not changed anything on it, no rom or anything.., not sure how to do it, so I am using it the way it came... first question, what can I get if I change/update rom or anything like that ?
second. autofocus on video is really annoying and only reason to get this phone was camera and video... I see that on miui website , they still didnt get any answer for this problem, so maybe someone here can help me with that. All works ok if I use some other software and MANUAL mode, but its pain in the ass to adjust everything manual all the time.. so is there any solution to that or no ? global 8.2 stable

It will wipe the cust partition. I don't recommend it though if you want to go back to MIUI..

So I see "NOOB FRIENDLY THREAD". Sorry if my questions are too much noobish.
I just bought MI5S on aliexpress with installed international version of firmware on my phone. And I want to know how to start?
1) How to unlock everything (+root) + install TWRP + update to latest firmware + backup. Is there a guide for novices?
2) Do I need mi account? (I never user xiaomi phones before)
3) Do we have any stable unofiicial firmwares?
4) Is there a way to disable all xiaomi-related things?

Hi I have a Mi 5S plus.
Would like to root for using some programs (gmd, Autovoice, few others).
Not interested in trying new roms, and prefer a simple root, hoping that I can receive Xiaomi software updates without big problems.
Possible? Instructions??

Hi, maybe not much of a n00b question but didn't want to make a new thread for this little thing.
I own Mi5S since yesterday 3/64GB version and first issue i've noticed is that its getting hot really quick (battery sensor in settings shows 38'C) i know it has Snap 821 but still, making a phone call and feeling hot in hand. Sure, the aluminium back is transfering the heat but its not a pleasant feeling. Is that normal with this model ?

Unlock, root, which custom
Hey experts,
I see a few questions pending, but I hope someone is gonna pick them up soon, and mine as well!
@sesser, mine does get a bit warm sometimes, but never to an uncomfortable level. Hard to say if you're more sensitive, or whether there's something wrong with your phone...
First a bit about my situation:
I bought the mi5s 3/64GB directly from the Xiaomi online store in China.
Unfortunately I dropped it within less then a month and now the 3 touch buttons are going crazy. Fingerprint scanner is still working fine though. I found a temporary fix with the apps "remap buttons" and "VirtualSoftKeys". But MIUI kills these apps all the time, so I have to re-enable them in settings/accessibility. Definitely not a long term solution!
I also managed to install the google play store. But it is unavailable quite frequently.
I'd like to install LineageOS as soon as there is a stable release. But until then, I hope to find a better solution than what I have now.
So here are my questions:
1) Does the MIUI.eu rom have any advantages over the Chinese version? For example I have quite a few system apps that are in Chinese. Would be nice to have them in English. Or getting the search bar in the notifications go to google.com... Or is there another stable rom you'd recommend instead? Or are the differences so small, that I should wait for LineageOS?
2) What reason should I tell Xiaomi for unlocking my phone? I read "My Mi5s came with a custom ROM. Please approve my unlock permissions so I can flash the official MIUI ROMs." But I don't think that works, as I bought mine straight from their website.
Thanks!

I needed to buy a phone and I didn't wanted xiaomi at all!!, But my mother told me "take it it's great my has it and she's loving it" and my father "its the only device you can afford, I don't allow you to spend more then that" so i bought the phone hoping that the phone doesn't comes with clear Android p system (there's nowhere on the internet that says if it comes with Android or MIUI)
I got the phone and it came with miui, I thought I can handle it, but couldn't, I though I could do something to change it somehow, I couldn't,
But it's is driving me nuts!!!!!!!
I hate xiaomi ( maybe even more then apple and to hate a company even more than apple it's impossible (until now)
Don't get me wrong, the hardware is pretty good but the software is awful
After a long introduction here's my question,
How can I earase, delete, conceal, the miui software and any memory, trace of xioami on the phone
Delete eve-ry-thing!!!!!!!!! And install fresh pure Android p system
Is it possible?
Please help me!!!!!!!!!!!!!! , (I'm serious, it's really important to me!!!)

Seriously, your post is ridiculous, no one is going to spoon feed you with step by steps. Especially, when they have been posted already a million times over. Did you even make an effort? There are 9 Pies roms available!
Everything you need is here, go back and read the agreement that you agreed to when you joined XDA. Then locate the search box, then use it to find your answers for unlocking the bootloader, flash Twrp, your Rom of Choice, Gapps, and Magisk root.
Next, Miui is actually, awesome once fully setup. You can disable the things that you don't like. The first time I tried Miui I absolutely hated it too. However, once I learned how to use Miui, it is one of my favorites.
Go try something else, but come back later and give Miui a try, many people ended up loving it. Finally, as a parent with teenagers. I fully agree with your parents, you should thank them. This phone is one of the best phones that comes wit Miui but will also give you whatever you want with it comes to the SDK : Pie, Oreo, Nougat each version of OS with plenty of Roms to choose from.

Thanks, but I tried the miui on the phone for 2 months now, and sometimes it's fine but a lot of the times it's really not. I tried to unlock, rom, twrp.... , But my mother said that I can't do it cause I might ruin it so I need to give it to a pro, my cousin is a pro in this kind of thing, but to give it to him I need to see him and that is a whole new thing
Another question, me roming, twrp-ing.......? Is it erasing the miui? Or just installing a new software on the "old" software?

Your base partitions remain. But yes, Miui will definitely be erased. However, it can be restored. It's very important that you or your cousin does the research before starting otherwise you can brick your phone.
Be careful to make sure that you properly unlock the bootloader. I would strongly suggest using Miflash or the all in one tool. Especially if you are new to this type of thing.
I just bought this phone and will have it in my hands by Monday. If you look at my history you will find that I write a lot of tutorials with step by step instructions.
Be patient and wait a week, This week I will join the Mi8 community and start making contrubutions. Likely by writing a very extensive step by step how to guide...if it's needed, or if I can improve upon what currently exists.
It is important that you establish a Mi account (if you do not have one already).
The first step will be unlocking the bootloader, then flashing the most recent version of TWRP. Then you will create a Nandroid recovery. This way you can restore your current instaltion if/when wanted .
Next you will wipe system, and user data, as well as the caches. At this point you can then flash your rom, gapps, and magisk root.
You can assure your mother that if setup correctly the phone will be secure, and you can keep the installation updated as new rom releases become available, these updates will typically include the up to date monthly security certificate,
Once you have everything installed you can then resync your user data through your Google account setup. Go ahead and ensure that everything is syncing to Google as well as the mi cloud.
Look for my future threads, Good luck, be careful.
Edit, after briefly reviewing some of the current tutorials. I will definitely dramatically improve upon existing instructions with threads that are specific to the Mi 8. and Mi Mix 2 and 3
So people will not have to rely on threads with out of date instruction. In example, there is no need to disable driver signing on your desktop.
See you soon

Recommendation on selling

Hey guys. I got the phone through contract extension, but sadly did a too short check if it actually can be unlocked. (Did remember reading about Nokia aiming to provide bl unlock for their devices and found those roms stating unlock is possible. While I should have taken a look how to unlock.). Now, I don't mind paying that bit, but I do have concerns first if it's safe to give these details to some third party service and then there is the question of developer support. The kernel sources are finally there, but no one knows if official unlock methods will be available. (Also not being able to install recovery because of updated boot partition ...) So I need some advice, should I:
A) Stay on the phone, pay the unlock, use LOS or some Treble Rom, hope unlock becomes available and whole situations gets better?
B) Sell the phone and get one with better support?

I think this phone is ok, you will have also android 10 official. As i can see, the support for this phone is ok, i have u11 life and no custom rom right now, also the same price in my country

Question Poco f3 bootloader unlock + custom rom

Hi everyone, I'm new to the community and I had few previous experiences with phone modding so I'm here to ask you some support. I'd like to unlock bootloader, root and maybe install a custom rom o just xiaomi.eu rom but I don't want to brick my phone. I don't know what disadvantages i get other than losing the warranty( i read something about banking apps and netflix). If someone could guide me or link to some detailed guide I'll be very grateful.
The first question about bootloader is do i lose data when i start the process of unlocking the first time and should pop up the error of 160hours? or i lose data only in the second "try" after 1 week?
As said i have a poco f3 8-256 if could be useful.

You won't lose data, at least in my case but just make a backup to be safe.
You can start here:
You can look at his other videos too about Poco F3. They are very helpful to me and it is in English.
I personally prefer xiaomi.eu ROM 12.5.19 gives me 700k AnTuTu, google apps, miui cam, good battery life, good gaming experience, game turbo, and debloated miui which is optimized for the phone.

Yes correct, your phone will only do a Factory Reset after the "2nd try", aka. when the bootloader gets actually unlocked.
On the 1st try, nothing happens with your phone, it'll just ask Xiaomi's servers to allow your Xiaomi Account to unlock the BL.
Munchy's videos (the video above that LynnnXDA linked) are a good starting point for info.
To give you useful info along the way, the other day I made a comment about the disadvantages of Unlocking your bootloader in this thread, I will copy&paste it here:
If you unlock your bootloader, you must be aware of the downsides. Some apps won't work (at least not without a workaround), like Banking apps, Netflix, Super Mario Kart, Google Pay.
That's cuz Google's SafetyNet API reports to those apps that the Security-Status of your phone is "Fail", because of the unlocked bootloader.
You can hide it with Custom ROMs that specifically list "SafetyNet passed" or by using Magisk Root with a SafetyNet Fix Module. Or Both idk whatever.
I use Xiaomi.eu Custom ROM on Android 12 with Magisk Root. Everything works, but this stupid cat & mouse game with Google and Android Modders definitely sucks.

I also made another comment about the risk of bricking your phone when flashing a ROM, in this thread:
Critical partitions are being modified in the Flashing-process.
There is no protection.
If your phone shuts down during the Flashing-process, your phone can get bricked (black screen) and you can't even boot Fastboot & Recovery anymore. I know this. I have experience.
You must ensure that you have enough Battery (I recommend 75% Battery at least), that the USB connection is stable (will not disconnect randomly), and that your PC won't crash/shut down.
IF IT HAPPENS, that the Flashing-process errors out, DON'T REBOOT THE PHONE. If you do so, you won't be able to enter Fastboot anymore. You must stay in Fastboot. Just reconnect USB, and try again to Flash. Just don't reboot the phone.
Sorry for fear-mongering, but this is definitely dangerous and not to be taken lightly.

Despite the disadvantages (which might increase, because of Google fighting against it), there are some nice advantages, like being on the cutting edge ROMs with the latest updates, freedom, Access to system files, System-backup/restore, Call Recording (which may otherwise not be available for you), Cool Magisk Modules, Mods and other things...

Yes correct, your phone will only do a Factory Reset after the "2nd try", aka. when the bootloader gets actually unlocked.
On the 1st try, nothing happens with your phone, it'll just ask Xiaomi's servers to allow your Xiaomi Account to unlock the BL.
Munchy's videos (the video above that LynnnXDA linked) are a good starting point for info.
To give you useful info along the way, the other day I made a comment about the disadvantages of Unlocking your bootloader in this thread, I will copy&paste it here:
I also made another comment about the risk of bricking your phone when flashing a ROM, in this thread:

The best drivers are included in Mi Flash, under the menu "Driver".
Before installing the drivers, I recommend starting Windows with Driver Signature Enforcement disabled.
Otherwise not all drivers get installed, because a few are not signed (They are safe to install though).
To temporarily start Windows with Driver Signature Enforcement disabled:
1. Hold SHIFT while clicking the Restart-Button
Windows automatically boots into Advanced Startup Options
2. Click "Troubleshoot" > "Advanced options" > "Startup Settings" > Restart
Windows boots into Startup Settings
3. Click 7 for "Disable driver signature enforcement"
Then when you're in Windows, you can install the drivers from Mi Flash.

Hi everyone, tomorrow i will unlock my bootloader and during this days I looked for some custom roms. First of all I want to ask you which are advantages and disadvantages of rooting the phone, I read about safetynet problem, and also some custom roms that are compatible with safetynet.
I'd like a stable rom but not stock like miui.eu, I was thinking something like lineageos or arrow os, what are the differences?

Hi All, what is best stable EU 12.5 rom for POCO F3 best better battery life?

Hi All, is it every time request unlock bootloader from xiaomi.com have to wait a week 7 days ??

@coolkillermax Yes, you have to wait.

Hi everyone, I'm new to the community and I had few previous experiences with phone modding so I'm here to ask you some support. I'd like to unlock bootloader, root and maybe install a custom rom o just xiaomi.eu rom but I don't want to brick my phone. I don't know what disadvantages i get other than losing the warranty( i read something about banking apps and netflix). If someone could guide me or link to some detailed guide I'll be very grateful.
The first question about bootloader is do i lose data when i start the process of unlocking the first time and should pop up the error of 160hours? or i lose data only in the second "try" after 1 week?
As said i have a poco f3 8-256 if could be useful.

I suggest reading this:
How A/B Partitions and Seamless Updates Affect Custom Development on XDA
You may have heard of Seamless Updates before. It involves something called "A/B partitions." What is it and how does it affect custom development on XDA?

Question Getting to know my Biloba - fixing it - nonGoogle

Dear tech friends
I happen to own a Biloba Redmi Note 8, and I understand now that it isn't the best phone for DIY. But I want to make the best of it as selling it will mean loss of money and overall I am very pleased with the thing. Or maybe 'was'? I hope I did not kill it.
The situation:
- it is stuck in a kind of startup loop that restarts endlesly. I need to put the phone in fastboot to give it some rest. I believe I managed to shut it down yesterday, but I do not remember how.
- this happened after I installed a (wrong?) recovery rom into the boot sector - this was before I realized how particular this Biloba version is.
- I want to fix it and put a google-less rom, perferably open source/GSI but if not possible official China Rom could be an alternative as it doesnt have Google.
My question to you is foremost: where can I obtain the knowledge to fix this myself? Ebooks, tutorials, Xiaomi service manuals? Mind you: it is BILOBA.
Also I havent found any decent MiFlash program. They all seem buggy as hell. Doesn't Xiaomi offer official tools for this?
Why is smartphone administration seemingly shrouded in mystery? Companies do not want us to amdinister our phones ourselves? PC technicalities are so much more accesible it seems?
Thanks people!

same here

I guess the best places are the threads on xda on devices that have more active modders.
I usually use 'Google', and mostly keep in mind a way to return to previous conditions.
Keeping a copy of original firmware ready helps there.
Also, I tend to flash with fastboot whenever possible.
Only reason not to is when I must flash when in BROM.
