I was on custom non miui based ROM and while signing up on miui forum app(wanted to sign up for miui 10 beta) I messed up the username. Someone suggested the only solution being delete mi account and create new one. I did that and everything worked good.
Problem got known when I tried installing miui based ROM. As soon as the screen boots, it ask for password of mi account which I have deleted earlier. I know the password but it won't work as account don't exist.
I tried getting support from mi support but they said only available solution is to go to service centre but is far from my place.
I have tried the following things:
Reverting back to miui 8 (as miui 7 is not available), this way I can access the miui ROM but still can't change mi account.
I have not yet tried mi tools available as they were not tested on mi max 2 and I am afraid it might hard brick my device.
If anyone have ever faced any such issue and found some solution, please share any info. Possible.
Note: My device is not unusable as I can install all non miui based roms but still this happened at the time of release of miui 10 which I cannot try anymore.
Please try to provide a solution that won't have the risk of hard bricking the device as this is the only device that I own.
Thanks in advance.
Try creating the same username and see if you can access the phone again on MIUI.

Isn't username generated at random, It just ask for email id, phone no.?
Also I don't remember the old account user name only first and last two or three digits as in screenshot:

Well, sorry to say but it won't work. It won't let pass the screen of login and account is not just connected to aim but linked with device as well. Even after removing aim and trying to boot, the screen to login with existing account popped up.
Thanks for replying though.
Anyway guys, romfactory helped me bypass the screen and thanks to him now I am on miui. Just minor issues are left to check so that the screen won't appear on next miui flash.
Thanks allot everyone who tried to help especially romfactory.

Sorry for the late reply. But it turns out it didn't work. Even after able to access Miui, the mi account and mi cloud force close keeps popping up every now on them.
Also the moment you restart either your device will go into bootloop or the log in to mi account will pop up again.
Which implies only solution is the official one i.e
1. To mail contact customer support and mail them whatever details they ask(screenshot attached), this one is free.
Note:
-This will take 4-5 days approx.
-Dont just mail to support at your own country. Rather mail to atleast 3,4 countries.
(3 of them replied copy paste unasked info. Whereas Malaysia and Singapore customer support understood my query and asked for further info as in screenshot)
-You can contact them from here:
https://www.mi.com/en/support/contact/
2. To take your mobile to nearby Xiaomi service centre(they need a copy of your identity and address proof plus a copy of your purchase invoice, they will charge a specified fee for it(180 Indian Rupees in my case)
Note:
-This one will take 2-3 days approx.
(Remember to backup and erase your data before handing it over)
-This solution won't always work as sometimes even the support centre don't know how to deal with this issue and they will try factory reset only. If it didn't work for you always remember to go back to first option.
Hope this helps.
Just to let you know I am still awaiting reply from Malaysian Xiaomi support centre. Also romfactory has talked to few of his friends who work in mi support so my problem will be solved in some time.

I saw in another post that the kernel source got released, Im new to this, I was reading a post about how to create custom roms and all that, and i was wondering , we do need root access to get the system files and all that to begin working on a rom ?
What i wanted to do was basically a full stock lollipop rom, but with the Axon Software ( Camera, Dolby Digital, and a few other things ).
I dont have any background expirience creating roms, but whats leading me to this is , loving the phone but hating the toggles, and a few other software bugs ive encountered.
I have some programming knowledge, and I will make this my little side project if theres any chance for it to be done. If anyone has some background and wanna help/teach me, ill be thankfull.
This is the link I been following.
http://forum.xda-developers.com/showthread.php?t=1801690
I have no programming knowledge, but I'll gladly provide moral support and encouragement in this endeavor! A stock lollipop rom with ZTE features would be spectacular.

I know right ? Well, If by any chance it can be done, ill keep trying. I guess first we need root.
I would like to support this and I have some java and c++ programming experience. The only problem is that there hasn't been any word on root methods or bootloader unlock methods. Supposedly ZTE phones come bootloader unlocked already, but I haven't been able to prove this since we can't access the bootloader via fastboot :/ if we can at least get root that would be a good start.
Marshmallow on Axon Elite?
Hi all,
I came across this poat while checking for new ROMS. If this checks out I would happily go for the Elite as the price point and features are value for money. For those of you who do have it can you confirm that this is actually a Marshmallow ROM.

You need to install Google Play Services and Google Services Framework. You will need to sideload these apk's. You will need to Google them.
Please, how can i upgrade my ZTE AXON Elite to Android 6.0? Is it posisible? Thanks
Marshmallow isn't available for this device yet.
When will a custom ROM appear for the Axon Pro?I hate all these chinese stuff and i would like to have the option to reset the phone and redo all the Gmail account,without the phone asking me for the last gmail account.I bought the phone from a friend and i did a reset later that day and it kept asking me for the old account.It sayd that the phone was reset and needs the old account and i couldn't go forward because it kept connecting to google and asked for the old account.I had to use my friends account again to use the phone.I want a simple rom,without this stupid connection to google and other chinese stuff.Any idea when a rom will be available?
No clue but now that you have your friends Google account you should be able to delete it and add your own.
I'm surprised that there isn't any custom roms for this phone yet,i mean its a phone with 4gb of ram,810 Snapdragon so its pretty powerful.

Yeah. I usually say something like "I am a developer working on advanced backup software and I need to unlock the bootloader to root on my device" or something like that. Anything that sounds legitmate should be fine, and I get my unlock codes pretty soon after that.
FYI, since this is the top thread when you search for "Redmi 4a XDA" on Google (not sure why) I figured I'd drop a link to the main thread for the Redmi 4a which contains all the info you need about root, bootloader unlock, custom ROMs and development: https://forum.xda-developers.com/general/general/xiaomi-redmi-4a-chat-root-sd-425-2gb-t3511933
i did it with my redmi 3. 1st request was left unanswered. a week later i make another request with same reason as you and it got approved the next day.i think it has nothing to do with the reason, but the time and chances that they go through your request.
Chances are the request approval is automated and it looks for certain keywords to approve or dismiss. Try again with some reason as in Post #4 it might work.
Instead of custom rom, give the reason as custom recovery and something like you are very fond of customizing your device
and also root can also be a good reason. You can tell them that you are a developer or someone who likes to find fixes for issues and for that you need to complete control over the apps
I just say " I want to full control on my device" . and I get approval after 4 hours
I said that "I'm developing something"...and...you know what happens...
Sent from my Redmi 3 using XDA Labs
The most honest answer would be...
"I own it and am not locked in with any carrier obligations"
But, I'd probably be a wise guy with...
"I own it and am not locked in with any carrier obligations and, if this request is denied, please provide me with a full refund and I'll be more than happy to return it to you then provide this information and a statement to the Associated Press."

i just fill that with
"my phone in bootloop mode, and I understand that I can only revive it by using fastboot mode without lost any data. please help me, I'm big fans of your redmi series"
maybe sounds funny, but I just got my permission a minute after submit that

hi all. have MI 8 with 9.6.4.0
downloaded MIUI 10 global beta and flashed using MiFlash utility but left the Clear all and Lock selected.
now I've a brick because: at the end when phone rebooted go to locked bootloader.
Trying unlock utility i get the green dot at "verifying device", but stop at unlocking with "current account not bund to this device" and i cannot change dev options in the phone as it's clean and don't have rom.
I'm sadly stuck...
Any suggestion would be really appreciated... ((

It is a very bad policy at least the can build in a warning in Mi flash.
Good luck, I heard s unlock works to get edl.
I've just bought this phone, I have a SIM that does support WiFi calling and VoLTE (it's EE in UK), but I don't see the option anywhere. Similarly I don't see a VoLTE option. I've been everywhere in the menus, and it's just not there, or in the phone app.
Is there some magic code I can type in to force it on, like *#*#86583#*#* on a Xiaomi ?
Do either of these work OK for anyone ?
I have version 17.0922.2005.11
I found the answer, and if someone else is looking, Asus needs to add your carrier / country VOLTE/VOWIFI profiles to their firmware.
I guess I have to wait.

Hi Guys,
Just finished adding some hours ago all what is needed to enable it for my ROG 3 and my carrier.
[Guide] Enabling VoLTE/VoWiFi v2 | XDA Developers Forums
I have rooted the phone...
1) download the bootloader unlock from asus support webpage and unlock the bootloader (!!!this wipes your phone!!!)...just select the model and they give you the apk.
2) download twrp custom rom and flash it in fastboot (you need drivers and fasbtoot tool)
3) install magisk apk and use the app to download the proper zip that has to be flashed via custom recovery to enable root
4) having root enabled now you can use the guide above and activate diagnostics (I had to use the remote port option as it would not detect it via USB
5) based on the guide I also used the Xiaomi mi9 mbns (sort of config files for volte and vofi) using my carrier file.
Rebooted and all works now
PS: I had to enable magisk hiding mechanisms to make sure banking apps are working also.
While at this I also added some ad blocking capabilities now that I had to have root
PPS: here is a guide for rooting....(https://www.ytechb.com/how-to-install-xposed-framework-on-android-10/)
for custom recovery (https://dl.twrp.me/I003D/twrp-3.5.0_10-0-I003D.img.html)
With the new update to a12, here in USA a lot of users can make or receive any phone call. with the A11 not issues. Any idea how we can fix this issue ? My phone is not rooted.
Information on how to downgrade is lacking, i have found one guide but the rom given fails verification
does anyone know of a way to downgrade as i cannot deal with android 13 and it's lock down of sideloaded apps
There is currently no way to downgrade back to Android 12.
I am able to side-load apps - but you need to allow the application you are using to download the APK (as in Android 11 and 12).

Is a shame spend this amount of money on a phone with this kind of support, No Roms online so you could restore the phone, etc etc... maybe will sell this phone and change brand again...
