I tried to unlock the bootloader of a Redmi 7a . But the Unlock Tool couldn't connect to the device. The device works fine with my PC. I could use it regular.
Adb devices..... says..... connected
But the Tool could not connect. I hope somebody can help, cause I bought this phone especially for rooting.
Thanks a lot
Drivers reinstall for adb and fastboot . Turn on oem unlock in developer settings , log in to account xiaomi on the phone and on tool . And try to unlock . Max 3 minutes . All data to be deleted .

When trying to unlock the bootloader I am stuck at 50% and it fails because it cannot verify the device.
My find device is set to on (some say it needs to be)
i have also tried to flash the dev rom using the flash tool but it runs to completion straight away and the phone remains in fastboot mode and doesn't reboot and so when manually rebooting nothing happens.
This is nearly 2 weeks of work to flash my phone because there is a virus in the Note application whereby advertisement banners appear when connected to the internet and with a malware scan the problem lies with a trojan in the note application meaning I have to flash the phone.
No progress at all in a week and I can seem to get around this 50% bootloader problem, does this mean Xiaomi haven't verified my request ? when logging into the bootloader it says checking permissions and then proceeds to log in, Its been 4 days no since I applied for permission to unlock the bootloader.
Help would be appreciated this is a new phone.
make sure you are on developer China rom , not stable
make sure you have checked usb debuging
make sure you are logged on mi account on device and on miflash

The developer rom flashes instantly like within a second so I am not convinced it has flashed.
usb debugging is on
find device is on
logged onto mi account
but how do you log onto the flash tool ? do you mean log into the bootloader unlock tool ?

yes, log on any mi account you can, i read that's help
anyway developer rom is A MUST, flash with sp flash tool and only system and data or via updater.

are you saying log into the mi account in the flash tool ? is that possible ?
Your adb drivers are not properly installed. If you are you flashing this with windows 10, do it on windows 7 of you have a chance, i had same issue.
I am having no success with this
hi, i have tried every possible ways to unlock the bootloader,which i found on web, but still i am unable to unlock it.. :crying: i have unlock permission, MiFlashUnlock isn't working after 50%.. found on web that i have to flash china developer rom first then it will work, but MiFlash isn't working, whenever i click the 'flash' button within 2s it shows flash done but nothing happens to the device.. download mode/edl mode also not working, whenever i enter this mode the phone automatically rebooting.. please guide me what to do.. trying different methods from last 4-5days, it feels really frustrating now, but i want to unlock the bootloader.. please help me with a proper guide.. thank you
You don't need to flash any Dev ROM. Just use older MiUnlock tool. Before trying, update your Mi forum account, log in to mi cloud, update phone's driver and then try. If it still stuck at 50%, then just wait for some more days. It'll unlock normally.
About edl mode problem, I'm having the same problem now. Please inform me if you get any solution.
Make sure you login to the mi cloud + mi account on your phone + mi flash unlock using your mobile phone number that you used to get the unlock code. I had Global Rom and was stuck at 50% but unlocked with Global Dev ROM. Coincidence or not? I don't know, worth a try.. If you're on the Global ROM you can flash Global Dev through the updater app.
yes their database isn't updated i guess.. i think i have to wait few more days!
Recently I have owned lenovo zuk 1
Then I try to unlock bootloader and root my device and get successful in this process and try some custom ROM's to make my handset with more interesting features ( thanx for the those developers who develop such ROM's , hat's to you guys) but after some weeks I try CM 14.1 , I messup with that process and got bricked device then I try to reflash that ROM , I have completed all processes very patiently , again and again I was ported to recovery ,not able to access my device. I became fed up with this then I leave my phone on customer care , after some days I get my zuk 1 with stock firmware
Now the main problem arises
Again I try to unlock my device
I have already install the adb and fastboot drivers and that working fine
I tried , adb devices
Its working
Then I try ,adb reboot bootloader
Its also working
But when I try , the script for unlocking bootloader
I get , { waiting for device }
Idk what's this happening
Lenovo USB drivers are property installed on my PC
Adb and fastboot drivers are also installed properly but I don't know ,what i am doing wrong
I think customer care ppls forcefully locked my bootloader that I can't able to root my handset in future
If anyone here to solve this issue ,ASAP

Buddy try this tool

Ive requested unlock and got granted. Downloaded Mi Unlock but looks like it cant find it cause the unlock option stays greyed out. The Mi Suite cant connect to it either.
With adb minimal i can connect to it and request and oem device info.
Installed many versions of drivers but never working. Any help would be appreciated
Thanks
Mi flash and minimal adb can see the device, unlock cant.
Account synced, device find on, usg debug on, same phone number, code validated.. I dont get it
........
Please, I need some help!
i have the exact same problem... no solutions so far but only got it yesterday so i hope i will figure it out. Have you figured it out? I want to try on another laptop / version of windows so thats my bet.
Had the same issue.....used another laptop and it worked. Both Laptops with W10 .....
EDL (Emergency Download) Mode has been removed/ disable from MIUI 8.1 onwards and Redmi 4A later Xiaomi devices. So you can flash MIUI Fastboot ROMs on your device by using Fastboot mode only, if your bootloader is unlocked. And, we can't use Qualcomm Jig Cable(s) also now.
So, we have only one way to know Qualcomm HS-USB QDLoader 9008 port from PC. It's Test Point Method. This method will work with every MIUI ROMs (Upgrade/ Downgrade) , Locked Bootloader/ Unlocked Bootloader and also work to recover from a Dead boot device (Bricked).
While touching these two points with a metal tweezers plugin the usb cable to the phone and PC will make the phone enter edl mode. You can then release the tweezers.
Bro edl mode is not removed. It's just moved to fastboot. You can enter edl easily by "fastboot oem edl" command. Hope this helped :laugh:

In any case, the bootloader muz be unlocked to initiate EDL using ADB fastboot..

What makes you think I'm so lame as well. I have used this command and flashed my mi max 2 with fastboot rom. Tho I don't remember if bootloader was locked or unlocked. Probably it was unlocked. But still no issues as anyone can unlock thier bootloader officially.
i wasnt intended at you. it seems they forgot some ways when they first deployed the edl blocking access but with the most recent "roms" they have blocked every access way to edl when bootloader is locked : adb, fastboot & cable
the only way left is from internal pins, but we can expect they will hide them even better on new phones.
Today it's much worth to wait 72h (+30days if you just already unlocked another one today) than opening the models that have "non removable" batteries and risking to leave traces/damages
it's really a shame that xiaomi lock their phone this way, it's a very bad message at the users (fastboot is so much restricted that you cant even switch between stable&dev anymore with locked bootloader) but we still have the chance that they allow unlocking and that this unlocking is a real one allowing full control
Fastboot rom isn't needed untill we brick our device and we can't brick the device untill we have unlocked bootloader. So basically edl mode will work when it's really needed.
It doesn't work for my MM2. Got it since 4/12/17. Didn't know i need to login to mi acc to register my device, set usb debugging, developer's mode, unlock status...I had the phone for less than 2 hrs after updating to MIUI 9 from ver 8 (using the updater app) before it suddenly froze up, crashed and went into bootloop. I tried contacting xiaomi svc ctr but those clowns refused to help saying my device is china export.
I cldn't even get them to help me register my device on my mi acc using the imei & s/n info. So if anyone could offer some suggestions as to how I could ressurrect my phone, I wld be most grateful. Failing which the only avenue is to bring it to a svc ctr in China to get them fix it.

My test points don't seem to work
I opened up my mi max2 and followed the steps to short the testpoints but my pc doesn't seem to pick up the Qualcomm device.
Anyway to trigger the thing so that the Qualcomm device can be detected?

I managed to short the test points and got the Qualcomm HSB device on the device mgr, flashed the mi max2 with the latest global stable (V9.2.1) rom. But the phone is still stuck at the Android logo with 3 dots...
I wld have thought EDL flashing wld have wiped out everything on the phone and start afresh?
I am now thinking of formatting the entire phone and reflashing it again. How wld I do that?
Thanks for any inputs.
Hi, Does EDL with test point flashing refresh the boot partitions?
I have shorted the test points and successfully reflash the phone with the latest stable global ROMs (even back to MIUI 8.5.6) but just couldn't get the phone past the MI/Android logo after restarting it
If the boot partition files have been messed up and EDL flashing is not refreshing these files, no matter how many times I try to EDL flash the device, it's not going to help. Pls correct me if I am wrong.
Any other options I can try?
