Well both the AFT and RAW mega folders need a decryption key to download.

if you unlock bootloader by tools of asus so after relock by using this method then warranty is back ?

Not iff the unlock tool is by ASUS... Their tool ends your IMEI or some phone identifier to the update servers negating any warranty you think you have after re-locking... If you used unofficial unlock then no identifier has been placed against your account, theoretically, there's nothing to suggest they can't detect unlocked bootloader with a little piece of programming added into their updates...

What rom are you currently running?

Hi Snort, yes, i tried this, i tried uninstall and reinstall all drivers, tried to format one notebook of mine, tried the xFSTK mehotd but ALL things and with different pcs AND cables, any pc recognize my cellphone, but it stills charge. That´s why or something is PRETTY screwed or i got a hardware issue.

do you know how re-lock the bootloader ? I don't found other procedure than this.
I have unlock with not official asus tool

I've tried the steps listed @ asus-zenfone (Google search for link)
This still doesn't work..While it helps you get back to stock (Steps are also listed here @ XDA), I believe the Asus servers keep track of your serial or IMEI. At this point, you'll need to manually update the OTAs software with ADB sideload. Luckily for us, Asus posts these on their support site for the phone.
Unfortunately this is bad if you're trying to sell your phone, but I knew what I was getting into unlocking it. No regrets.

Mi5s Plus bootloader unlock problem

Wondering if anyone is able to help me.
Recently purchased a MI5S Plus and having problems unlocking the bootloader. Followed all instructions and the unlock fails at 50% with the tool stating that "the account on the device is different than current account" (or something like that).
Now here's what I have done so far:
-made sure device and tool are using the same account with phone number login
-made sure "find device" is turned on and phone can be found
-disabled windows 10 driver signature
-enabled usb debugging on the device
-made sure sim card is in slot 1 of device
So far no dice. Phone is on Global Stable (8.0.1.0) but I wanted to move to EU version (which also has the correct UK locale and some other features). I am not new to the rom flashing scene (just moved from iOS to android and had a Galaxy S2 back in the day).
If anyone could help me with this it would be greatly appreciated. No idea what else to try.
Best regards

I think what this means is that your phone is associated to a mi account different than the one you have logged in to unlock it. Make sure your phone has the same mi account as the one you are using to unlock it.
Good luck!!

Yes it's the same account in both places. I double checked that.

Hi, I will share some of my experience.
Myself had that problem too, bought mi5s plus on global 8.x.x and wanted to move to eu version . The problem with this phone is that there's no global dev rom for it just yet, and you can't officially flash the china dev rom, since the installer doesn't recognize the package. So you find yourself in kind of loop, like
==> to open bootloader you need dev rom (only china available) :/
==> to flash china dev rom via mi flash you need to get your phone to EDM ( Emergency Download Mode ) .
But to get to EDM you need open bootloader.
That's kinda sucks, but i kept looking over the internet and found the overall solution that will probably work on any xiaomi device. And that's to make "Deep flash cable". This cable let's you enter EDM ignoring the locked bootloader, this way you can flash the china dev rom, and from there open the bootloader.
The idea is really simple, just need to shortcut any of the middle connectors of the usb with the ground(the outter connector) when plugging the phone into the pc(don't even need to cut the original usb cable), that will prevent the phone from starting to charge and it will enter EDM (pure black screen without any sign of life, but pc will recognize it on COM port as long as you have qualcomm drivers installed.) In this mode the mi flash tool will recognize the phone and you can flash the china dev rom.
If you need more help just ask, and u can find some nice guides on youtube that explain how to make the cable. Good luck!

Thanks makslll, I have mi5s, wondering if the process is different?
I bought my phone with the xiaomi.eu rom (8.0.10.0 MAGCNDH), unlocked bootloader with "MiFlashUnlock_1.1.0317.1_en" and installed recovery following this (https://xiaomi.eu/community/threads/6-12-1.36462/). After this I was able to install other ROMs .
Hope this helps

Main problem I'm getting at the moment is the fact I can't get past the 50% on the unlock process. Keeps giving me an account error on the Mi Flash unlock tool. Something like "Account on the device is different from current account".
In any case I was looking at this EDL solution but let me see if I grasped this:
-I can use EDL to bypass locked bootloader restrictions. Could I just flash the EU rom without unlocking the bootloader?
-That not being the case, I'm guessing I would need to flash something like China Dev and the try and unlock the bootloader followed by TWRP flash, etc etc.
If someone could shed any light on this that would be great.
Thanks in advance

Thanks will give this a bash later on after first trying to factory reset the phone.
Thing is I read about a lot of people being successful unlocking their bootloader on Global Stable rom, so no idea why I can't do it. Pretty sure I have all the necessary drivers and I'm following the process as it should. Still getting the account error.
Xiaomi should sort their **** out...
Thanks everyone for your help!

You can't flash Eu ROM with locked bootloader, since you need to use special image files of the supported roms for miflash (Can't use the .zip roms that we flash via recovery), and those available only for the official roms ( global stable, china stable, china dev).
So yeah, unfortunally this would take little longer, but i can assure you this method 100% works and it's not very hard once you've done the tricky thing with the deep flash cable =)

On another note, if a Global Dev rom is released for the Mi5S Plus, are you able to flash it as normal through the updater app?

Yes, on my gf's mi5 i just flashed global dev rom from the updater and unlocked it easy, they really should just remove the global <==> china barrier
Update: there is official Global Dev ROM available now, so no "deep flash cable" is needed anymore, just download the ROM, copy it to phone memory, and flash it via updater, good luck =)
So, quick update.
Managed to unlock bootloader last night by updating to the new Global Dev for the Mi5S Plus.
However a new problem has arisen, as usual. Using ADB, it recognises the phone whilst in normal mode with USB debugging on. The moment I reboot it into fastboot mode (to flash TWRP), it doesn't recognise it anymore. The drivers are installed as I disabled windows driver signature verification, but the phone is just not recognised anymore.
Anyone have any idea how to fix this?
Thanks in advance.

Virtually impossible to unlock bootloader

Guys, I need some help to confirm the only solution I found for my problem, or if I can still try other solutions.
I bought a Mi5s that already came from seller with the global stable rom. I asked the official bootloader unlock to Xiaomi and has received authorization by SMS. But the unlock application stucks at 50% saying that the device being unlocked is different from the one authorized on Mi account. I looked for some solutions like deleting all the devices in the page i.mi.com, leaving only the Mi5s, but I did not have success. Other solution is flash chinese developer rom
Another solution is to flash Chinese developer rom, to confirm unlock of the device on the developer screen and then to use the official tool unlock. But I didn't find any way to flash the developer rom. I've tried using Chinese PC Suite, fastboot mode, MiFlash, and all says that the rom I am trying to flash (Chinese) is different from the rom of the device (global).
The only solution I found is to buy a deep flash cable and flash the developer rom in EDL mode. Or hope to launch the global developer rom for Mi5s, which so far we have no prospect in the short term.
Do you suggest I try some other solution? Thanks in advance.
Try logging into mi cloud with your mi5s using the same account you used to asked the request to unlock.

Already had done it, no success
From http://en.miui.com/thread-482266-1-1.html
Under settings/additional settings/developer options, click Mi unlock status. Click add account and device. Your device will now be automatically added to your Mi account.
Next,enable OEM unlocking and USB debugging under developer options.
Then connect your mobile to the pc or laptop while on fastboot mode. Unlock again. This time, it will be successful!
Same problem. Can't unlock my Mi 5S on Global Stable firmware (V8.0.3.0). And can't flash to China Developer firmware.

According to this:
http://en.miui.com/thread-202290-1-1.html
You should have that parameter no matter you are at global or not, but if you don't you should flash a developer version, instruction at the same page.
Before you say "i can't flash developer rom", did you tried the updater app to flash it?
Force flash your rom using special cable to enter fastboot to install. I dont know its detail, but the installation called Deep Flash using deep flash cable sold on ebay

I had similar problems and I was also trying to figure out what to do to unlock bootloader on Global stable rom. The amount of people having the same problem where unlocking app stops at 50% is overwhelming ,judging from the comments found on google, but the info what is the actual problem is next to none. Suggested solutions looks to me like voodoo and most if not all probably doesn't have any impact on successful unlocking. As the Xiaomi unlock app is just a wrapper for fastboot executable I've checked what kind of commands are being send to the fastboot when you click unlock here they are.
fastboot getvar product
fastboot getvar soc-id
fastboot getvar soc_id
fastboot getvar board_version
So I've checked if I will actually get any info from bootloader if I send those commands manually, and with no surprise I didn't get any. So this was the problem at least in my case. Some kind of connection problem I'm not sure where exactly the fault is, probably drivers but try to issue those commands manually from command line I can bet you will not get any info from the phone. What to do if that's the case remove and reinstall drivers, this is what has worked for me. Good luck
Had the same problem. Got it solved today. the bad news you need a deep flashing cable, good news you can make it yourself.
Here is the guide:
http ://en.miui.com/thread-310325-1-1.html
http ://en.miui.com/thread-299790-1-1.html
I have unlocked 4 mi phones with no difficulty. Some of them with fake/seller ROM. Once you got permission make sure you have done all things right before preceding to Unlock. Usually it's all about loading the right driver for Xiaomi phone. Using default windows driver is not working. As it's not Microsoft signed driver you have to start windows in insecure mode.
You have to login in your mi account both on PC and on phone with SIM card ind.
Check that phone is verified settings/mi account on your phone.
Best luck
Something is with drivers for your phone. I have the same problem...than i delete drivers and than they automaticly reinstall and evarything works.

Follow the guide that I posted to make the cable(first link), install all the drivers and software needed (second link).
After successfully putting the phone in deep flash mode you need to update Qualcomm drivers (under device manager it must appear as com3 or com10 port after that).
Then use Mi Flash tool to flash Chinese dev rom (http ://bigota.d.miui.com/7.1.20/miui_MI5S_7.1.20_229fa68558_6.0.zip). If the flash fails the first time reboot the computer and try again.
After that sync connect your MI account to the device, enter Dev mode and you will find OEM Unlock option.
Not easy but it works.
Good Luck!

Follow the guide that I posted to make the cable(first link), install all the drivers and software needed (second link).
After successfully putting the phone in deep flash mode you need to update Qualcomm drivers (under device manager it must appear as com3 or com10 port after that).
Then use Mi Flash tool to flash Chinese dev rom (http ://bigota.d.miui.com/7.1.20/miui_MI5S_7.1.20_229fa68558_6.0.zip). If the flash fails the first time reboot the computer and try again.
After that sync connect your MI account to the device, enter Dev mode and you will find OEM Unlock option.
Not easy but it works.
Good Luck!

I tried all the possibilities described, that do not need flash developer rom using a deep flash cable. I changed drivers and everything, no success.
In time, I already ordered a deep flash cable here in Brazil. For my part, I thank all fellas who tried to help me but gave up trying anything else. As the title of the topic, my device is currently virtually impossible to unlock in the normal way.

Hi, what exactly did you do to succeed? Thanks.
I am stuck on Mi5s with 8.0.3.0. global stable ROM and the unlock blocks on 50%.

I have same problem to unlock Mi5s before but then realize that you need to update driver on your PC from Keadcom (or samething) into Marshall London Bootloader and it success.
Now my Mi5s uncloked officially.
I just use same Mi account which has permission to unlock my previous device which is Mi5.
No need deep flash cable, just normal cable can do.
Hope this help.

Unfortunately this this did not help. My assumption is that 8.0.3.0. Global stable needs ROM-internal permissions, which are currently missing. (In fastboot mode ADB is able to communicate to the phone, so it is not a driver issue.)

Pixel 2 XL no operating system fix

So I recently got my hand on a pixel 2 xl without the operating system.
I know this is an issue happened to some devices and the best way is to send it back to Google for a replacement.
However neither do I have the box and receive with me nor I am living in the official launch area. So there is no easy way for a replacement from Google. (I can't even post question at there official pixel user forum)
Therefore I really would love to know if I can indeed install the official ROM with tool like this one? https://forum.xda-developers.com/pixel-2-xl/development/tool-tool-one-driversunlocktwrpfactory-t3730226
And hopefully won't wasted a good device.

Did you have OEM Unlocking checked in Developer options before it happened? If yes you can flash factory images
If you have the stock recovery and can boot into it you can adb sideload the most recent ota zip.

Thanks for the answering guys, however I think it is one of the machine that Google ships with a OS in it... so I don't think OEM unlocking is enabled nor the recovery is working.

You can get the bootloader lock status simply by booting into the bootloader. Locked or unlocked? You don't "think" it has a working recovery is not good enough to help you. If it does have a stable recovery, you can flash the OTA. If it does not and the bootloader is locked you are S.O.L. and the phone is dead. Follow this video and let us know.

If you can hold down volume and hit power to get into bootloader and choose Recovery, you can fix this phone.
Go here: read instructions at top. You will be booting to bootloader, then to recovery, then choose Apply Update from ADB.
Then give adb OTA command as described. Don't skip or modify any step.

I am in this exact same situation. Did you ever figure it out? Or did anyone figure it out?

Just use deuce script to flash the factory image guys. That's what I did when I got the no os message. Mines started when I ignorantly thought I had to relock bootloader before flashing stock.

Locked bootloader wont let me use the script.
If your bootloader is locked with no way to unlock it, and with no working recovery, you're screwed. The device needs to be sent to Google to fix, which is rather problematic when the device is in a country where it wasn't sold.

yes,you can!only support CN firmware,but WW firmware upgrades are not supported. The WW version of the firmware upgrade, you need to download the update package to the root directory, restart the phone to detect the update.

Damn! I should have waited for this. Too late. I used unlock tool. Now Asus has my unlock info.
One question. Can I relock if I originally unlocked using asus unlock apk tool???
to confirm.......
i have a factory locked, untouched WW 512 unit. If i use this tool, i can unlock WITHOUT Asus knowing? no downsides?
@johnny886,
Thank for this, I waited for something like this, wanted to unlock the bootloader without using that app that gives IMEI to asus, a total offline boot-loader unlock.
although i stuck in step 3 ".update_image_EDL.bat”, dos prompt instantly closes. It may be a driver issue, as im not familiar with drivers for this phone, can you upload the drivers, only thing missing in this pack.

There are no disadvantages, the only benefit is that you can unlock your phone through EDL mode, no need to install UnlockTool.apk to apply for unlock! The ASUS server will not get your unlocked status, you can get upgrades via OTA later.

How about Burnt Fuses? Does something like this occur? Basically, i want to ensure that the fact that ive unlocked is hidden for warrenty. (I can always re-lock before sending back if i need to)
It would suck for them to tell me, that they wont service it because it was previously unlocked.

Hi, i tried but stuck on step 3, any way to solve? tried to change the usb port but same thing happened.

@johnny886,
Hi, I installed the Qualcomm drivers but for step 3 "1.update_image_EDL.bat”, it still prompts and closes immediately and I'm not sure how to QPST or QFIL. Are there ways to fix the bat file or provide a more detaisl on using QPST or QFIL please?
You can root without unlock bootloader?

So I did this and now my headphones jack isn't working. Has this happened to anyone else?
Update: The current workaround is to use the headphone jack of the included cooling fan.
Update 2: So it may have something to do with the bootloader that was flashed during the EDL unlocking process, which seems to be a generic SD855 bootloader. I came to this conclusion after I noticed that I was being limited to 70% battery charge. I flashed the WW 1910.35 OTA from ASUS' site and the battery now charges to 100%, but the headphone jack still remains broken. I will try to flash the WW 1910.44 update through fastboot when I get home, which I'm hoping will have whatever partition that was overwritten during the unlocking process.
Update 3: I figured it out. After using "fastboot flash boot TWRP.img" to boot into TWRP initially, I didn't flash the stock boot image again. This broke the headphone jack. So after booting into TWRP using that command, I had to flash the stock boot image first, then flash the TWRP and Magisk installers in that order. Hope this helps someone.

Question Bootloop to fastboot logo and back in lock state

Hi everybody,
yesterday I tried flashing the stock pocof3 rom back onto my phone, but since it got stuck in a bootloop at the fastboot logo. Showing the poco logo for a milisecond and then straight to fastboot..
(before this I flashed twrp and the arrowOS recovery and images a few time trying, without succes, to install this rom)
Last thing I did was flash via the mi-flash tool and did't see the "clean and lock" selection so it's also in lock state again.
I cant get adb to find the phone although the mi-flashtool is finding it.
anyone any tips?
I tried the vol up power trick, but this didn't help, keeps loading into fastboot

BAD NEWS... your Poco is bricked. You cannot flash ANYTHING using a PC when your bootloader is locked.
(I did same thing on a Mi11 5g last week and ended up selling it on eBay for spare & repairs
I tried sideload flash, miflash, copying update.zip to internal storage via ADB, and many other options - all without success).
- if your POCO is under warranty in your country (i.e. not a chinese import)... contact Xiaomi Support they can re-flash correct ROM
- Ask your local phone repair store... they *might* be able to flash original ROM back by using "Chimera" engineering software.

- Bootloader was re-locked whilst a custom ROM was in the phone.
(MIUI with Locked bootloader will not boot up where ROM is not stock or does not match the region/product code).
You cannot apply for bootoader unlock because you cannot boot up into Android and request the unlock via Developer mode.
You cannot remotely (via PC cable) flash any ROM into a Xiaomi / POCO phone whilst botloader is locked.
You are in a chicken and egg situation.,,, but if you find a way to repair your phone, please let us know how you achieved it.
Good luck!
If the system hasn't booted up yet there is a chance that you will be able to unlock bootloader again. Try it.

Connect the phone to pc and do the bootloader unlock again via the mi unlock app - you don't need to apply again and stuff as long as you're able to recognise the phone inside app correctly

Isn't there like a system that it checks the signature of the ROM and if it's a signed ROM it allows the flash? Or am I mistaken?

Nope bootload locked = no 'remote' flashes via pc
Apparently there is an 'authenticated user' mode for Xiaomi engineers in MiFlaah and also an EDL Emergency Download Mode which you can trigger by shorting out 2 pins on the motherboard so bypass bootloader lock and flash any ROM
Neither were available options for me

If all fails i'll try the shorting by pins, should be interesting
I think a warranty repair claim is your best bet ... I have never read anywhere that unlocking bootloader invalidates Xiaomi warranty (Unlike Samsung and so many other brands!)
If warranty repair is re refused try a few independent repair shops
Last resort is get the back cover off the phone and short out the EDL pins
Good luck!
