gt good developer rom for me? i using note3 snapdragon

same problem here, i tried to sync with mi cloud but still it failed. using latest dev rom 6.12.8.

Be patient and try everyday. It takes time for your details to be updated on their servers. You can also contact their customer support team and ask them for help.

I also faced some problem for many days. At last I deleted my old account and apply with new account and unlocked in seconds. You my try it. After unlocking you may switch to old account.
But first install dev from.

Anybody with a Kate (Special Edition) officially unlocked?

Hi,
I am trying to officially unlock for two weeks now.
I just get stuck at 50 with the Cannot Verify issue.
Opened a bug report here. Would be nice, if some of you with the same issues could support it.

just don't make any change on your phone and your mi account for about a week
Just wanna clear things up! Kate can be officially unlocked,
I had already done that way back in July.
Steps taken by me.
1. Boot into EDL mode
2. Flash Global Developer Rom
3. Login to MI account on the phone
4. Boot into Fastboot mode
5. Unlock with official tool
Tried everything and now flashing Dev Rom in EDL Mode
Still no more than 50%
I have unlock permission but fails at 50%.
Gonna wait for a few days before trying it again.
Apparently you can flash TWRP/root via this method without unlock the BL.

I updated to Global Developer with the updater app.
Had to reflash the rom with EDL, because it didn't accept my passcode any more (two weeks ago).
Still doesn't work.

Have you removed your lockscreen? fingerprint, pin, pattern, etc?
Please ensure that you've fulfill the requirements, because that point above is usually forgotten when doing this.
Kindly check it again.
Thanks.

Are you really using Kate device? Delivery outside Taiwan began 26th of August at geekbuying, AFAIK. When you bought it directly in Taiwan:
Was it originally equipped with Android 5? Which ROM did you use when you unlocked it? Where can we download it?
We other people received our RN3Pro Special Edition already with Android 6 installed, and after flashing all ROM fitting onto Redmi Note 3 Special Edition (not Redmi Note 3 Qualcomm China, not Redmi Note 3 Qualcomm Global) I *know* there is no working solution except unofficial bootloader unlock. For now, because I'm hoping Xiaomi is working on this issue.

Unlocking Redmi 3 Kenzo Bootloader

I tried a lot to unlock the bootloader of my phone but I am getting the error that says account on device is different from the current.
I have tried everything that I found on the MI Forum:
1. Flashing and trying to unlock through China Dev ROM
2. Going to i.mi.com and invoke find device and then unlock.
3. Relogin on mobile phone and login through Mobile Phone everywhere.
4. See if device is shown on i.mi.com
5. Tried on 3 different computers 2 physical and one VMware
6. Tried after 2-3 weeks
7. Mailed Xiaomi
None of the thing worked for me, I have posted regarding this multiple times on Mi Forum but the mods just send me links of things which I have already tried and when I say that it's not working they stop responding and then when I make a new thread they delete it.
Please help me and please don't ask me to unofficially unlock because if it fails then those idiots at Xiaomi will not fix it.

Have you tried flashing a different ROM? People here: http://en.miui.com/thread-226193-1-1.html had success by doing that. Try flashing the Dev ROM for your phone here: http://en.miui.com/download-301.html . If you try this and it doesn't work out, it's probably best just to unofficially unlock it.
Do you have access to a VPN? I've heard some people have had success logging into a server in Asia somewhere (taiwan, korea, china) and then using miflashunlock tool. I can't say I've had that issue. Do you use phone number to log into i.mi.com or do you use email? I've only ever used email to link my phone and the account, and it's always worked.

Unable to unlock bootloader

I had received the bootloader unlock permission for my kenzo on December 12th, but whenever I try to unlock, the notorious "Couldn't verify device" error appears. I've been repeatedly trying to unlock for the past few days, but in vain. I have only one Mi account, which received the unlock permission, and my device and laptop are logged into it. I have tried all of the following tips prescribed in various forums:
1. Tried signing in to i.mi.com and use find device service.
2. Disabled driver signature enforcement in my laptop.
3. Removed pattern/pin and fingerprint.
4. Bind Mi account for unlocking in developer options, but it shows some 86012 error.
5. Flashed MIUI 8 global developer rom 6.12.22 (currently using it).
6. Emailed Xiaomi India service, which advised me to take my phone to service centre!!
7. PM'ed some mods in MIUI forum about the issue.
8. Tried different versions of the MiUnlock app.
9. Tried doing it on different USB ports and different PC.
10. Patiently waited for many days. :crying:
I have all the necessary drivers installed in my laptop, and of course, I have enabled OEM unlocking and usb debugging in developer options.
So, after patiently waiting for 16 days after receiving unlock permission, I am ultimately about to give up on this. Is there anything else I can do to get my device unlocked?? (PLEASE DO NOT SUGGEST UNOFFICIAL METHOD).

Yea...good to know...for some users it gets unlocked without any hassle, even on global stable ROM...it just depends on whether your device details have been refreshed in xiaomi's servers...
Yeh...Global stable Rom can also be unlockable.
It's been 5 days but still no luck

It doesn't matter, just wait for 4-5 days without trying to unlock the phone and try after 4-5 days , your phone will be unlocked..
Older version dont work. Still binding time is too short. Any solution? This process is insane. Wait por 3 days to unlock, xiaomi sucks.

This device is associated with an existing Mi Account

Hello guys,
Purchased a secondhand redmi 2gb MTK phone of gumtree two months ago. It had a lot of bloatware and i recently flashed a new rom. I followed this https://www.youtube.com/watch?v=kq94VhG4UqA video but installed this rom .
Everything got flashed ok and I booted the phone to set it up. Go through language selection, locale and wifi but it does not let me get passes the next step. It keeps saying "This device is associated with an existing Mi Account (161****933) enter password to verify device.
Unlock number ###########etc".
I can't contact the seller as I purchased the phone over two months ago and have lost there details.
Can someone help, just want to get it to work, don't mind installing any rom so long as it works.?

Hi guys,
Could anyone help before I give up and destroy the phone?Adarsh tried but we could not get in to EDL mode.
I got the unlock request approved by Xiaomi today but when I tried to unlock, lo and behold it said that it can not unlock as the phone is not associated with my mi account.
Going crazy trying to sort this out.

Thing is Xiaomi keeps bootloader locked, to track phone through mi account. If in case phone is stolen, the thief couldn't flash another rom to use the phone. Now however this is good implementation but it's pain in the ass for us too..
You are in a situation where, xiaomi needs the same mi account that was created when phone was used first. Since u don't have that account, so won't be able to unlock phones bootloader officially. Without unlocking bootloader u won't b able to flash rom. Now ur only choice is unofficial unlock and that I think is bit buggy.
Unlock it unofficially and change the rom, thats it. Also before flashing any firmware zip in future please confirm with the uploaded that bootloader will not relock. As some firmware do relock the bootloader.
Now head to the unofficial unlock thread and follow the steps.. Happy unlocking

I think ur device drivers are not installed properly. Please check above guide and report.

Hey guys,
He has Mediatek device. For MTK there is no EDL mode. Just find MIUI older versions (like 7.X) according to your device and flash it vja SP Flash tool. You will need fastboot rom, but to flash, you have to turn off your phone and keep pressing vol+ button. Detailed instructions you can find together with the rom in en.miui.com
For mtk users (and possibly snapdragon) this work 100% . install clean first(old) china developer official firmware from miui.com (it may also work with new firmware or stable ) and open phone in fastboot mode and run from "remove mi cloud tool " _Upgrade.bat Done ! Create new or login with a real / good mi acount and activate associate the phone with new mi account. Xiaomi will delete old account and done . After that you can deactivate association and the phone is clean clean Use this only if the phone is truly yours ! Remove mi cloud tool - https://drive.google.com/file/d/0B_ZGSOigBwWJVW1CYWplUFk3b28/view

First remove your MI account & do a factory reset, check whether its asking for a new account or the same account used earlier.
If its asking for new account then simply skip it, reset again & handover to new owner.
Mi Account login in second hand mo.
Do not worry guys if anyone buy a second hand redmi mobile when u get it that time replace ur mobile number place of first owner mo. number. U would be access mobile setting and all things. Now mi account id remain will be same which was in past just ur new mo number will be linked that mi id of second hand device.

The system has been destoryed message

Hello,
Suddenly, just 1 month after the end of warranty my Xiaomi Mi Play stopped working showing "The system has been destoryed" message on recovery. I have read some articles and I have found that this could be fixed by flashing the ROM, but my problem is that bootloader is locked and I kept in this way for security purposes.
I know I can use the target app (https://c.mi.com/thread-2262302-1-0.html) to unlock it, but it also need some steps at android level (per attached image), which I don't have access anymore.
So my question is: add my account for unlock the unlocking permission is something which is at phone or at account level?
I mean, if it's something at the phone level there is no way to fix, but if it's at account level, I may fix the issue by using another Xiaomi device.
Can someone please clarify to me, or may I have any hints please?

Mhhh.... it seems something related on phone:
https://c.mi.com/thread-1857937-1-1.html
So, probably phone is bricked and there is no way to recover except than support center.
Hello,
I ran into the same issue a couple of months ago. I was EU rom using mi flash and accidentally selected the 'clean and lock' option. There are a few ways you could try to fix your phone:
1. If you have a mi account that is registered to the phone, you could login to mi unlock using that account and try unlocking the bootloader and then flash using mi flash.
2. If you don't have a registered mi account then your options are pretty limited. You could try a go to a service center but like me there might not a one in your region. The only other option edl test point. There are many people, mostly russian or indian, who have an authorized mi account and are selling their services. A quick youtube search and you'll find many options. They remotely connect to your computer and use their authorized account to unlock your bootloader and flash the factory rom. They usually charge anything from 25 to 30 usd.
There is a way you could apply for authorization from mi but judging from the many forums it is vary rare to get a reply let alone get authorized.
Unfortunately there is no other way to Unbrick your device until now.

Hello,
Thank you for your reply.
My Mi account was registered on the phone, but once I login to "mi unlock" and try to unlock, I got the error attached.
I am suspecting some operations on the phone were required in advance.
I mean, I have never applied for my Mi account to being able to unlock or something, is there a specific page where to do now (e.g. on a differenr Xiaomi phone, online, etc.)?

Hello,
I have checked on other forums but it doesn't seem that Mi Play has an edl test point.
Or I couldn't find the correct information...
