Hello , my name is Nikolay Iliev , I'm from Republic Of Bulgaria , i'm writing you this email about the following problem.
I'm using a mobile phone Xiaomi Mi A3 European Variant - Bought from Mobile Operator A1 in Republic Of Bulgaria.
The phone is Running the latest stock ROM and stock Firmware - 10.3.14.0.PFQEUXM with a locked bootloader.
But when i open the Xiaomi Test Menu by this combination of numbers *#*#64663#*#* pressed in the phone application and i press VersionInfo in the menu , it's written EFS:invalid , but in the same moment i have a valid IMEI NUMBER , SN NUMBER , PHONE S/N and a working Cellular and Wi-Fi Connection - But my MEID NUMBER IS 000000000000000 , and it's written EFS:INVALID.
I please you to explain me is this normal for the Xiaomi MI A3 to have the EFS:INVALID in the test menu , and if it's not normal does this message mean that the EFS Partition of the device is corrupted.

By their understanding the device is corrupted
Not sure what's your point, even on 4PDA people told you that it's normal. Default answer of support team is to perform a factory reset, I doubt that they understood your "problem" (as it's not a problem). Friend of mine has HW issue with his Samsung phone (display failure) and guess what support told him, "please do a factory reset".

Hello everyone, I have a problem on 2 telefoni.Ho purchased 3 redmi notes 3 pro (SD) for my family, one arrived with Italian and the other 2 no, I upgraded via miflash to my and I mounted version "Note 3 qualcomm last global developer version fastboot" on the official site en.miui.com and work fine on my device.
I then tried to do the same procedure on the other two phones arrived in China and end of the flash without any error and selecting the option to flash, none of the two phones on but at some point I get this error message:
Encryption was interrupted and can't be completed. As a result, the data on your phone is no longer accessible. to resume using your phone you need to perform a factory reset. when you set up your phone after the reset you'll have an opportunity to restore any data that backed up to your google account.
The phone at this point is blocked, dont start.
The bootloader is blocked!!
To remedy I tried to flash another rom, rom work with the other mobile phones but no longer read the sim !!
Now the questions are two:
1) How is it possible that on 3 identical cell and performing the same procedure one works and 2 no ??
2) that I could mount version that has the Italian as the language ??
If you were to continue to have the error not advise me sims to perform the procedure for the recovery dell'imei ?? I checked in the settings and under the written SIM1 and SIM2 is an IMEI code ....

Hi Dear, I have same situation like yours
did u find any solution?
best regards
Did you select clean all before flashing ?
Read this thread
https://xiaomi.eu/community/index.php?threads/35527/
I apologize for writing late but I really take long to find the solution to my problem that I have solved the question in a casual mode...!!
I purchased this 3 cell, at the same store but at different time, the first phone is a snapdragon edition, but the other 2 phone are SPECIAL EDITION....
The store sent me the different phones and do not know why, without telling me, the outer box is not clear, bear the same inscription.
I found out by accident, approaching the phones, I realized that one was slightly longer than the other and doing a search I found the measures that explained the difference, are therefore come to the conclusion that the two phones arrived after they were SPECIAL EDITION, would never have started with the Rom Snapdragon, downloaded the correct version everything is back to normal !!
All's well that ends well!!
Thanks!!
The short history:
Playing with an "official" ROM I bricked my phone. I was able to recover it, everything works properly except the telephony, I can't make phone calls :crying:.
The full story:
The behaviour of my phone is different depending on which slot I put my SIM card.
If I put my SIM on the first slot, when the phone reboots it doesn't ask for the PIN and doesn't recognise the card. But if I switch to plane mode and I reboot the phone, the phone then asks for the PIN number. If I introduce an incorrect one, it recognises that it is incorrect ans ask for a new one (then it is reading the card to know that), but when I introduce the correct one, it does no connect whit my carrier (of course, before that I switch off the plane mode).
If I put my SIM on the second slot, it asks for the PIN number but similarly to the previous case, It doesn't connect with the carrier.
In both cases dialling *#06# on the phone, I can read the two IMEI and the MEID codes and they agree with the codes printed on the phone box.
Moreover, if I install an app (I tested with some of them) that reads the SIM card it can read the name of my carrier and all the contacts that are on my SIM.
Things that I tried:
0) I tried to use my SIM in another phone, and it works. I also tried to use another SIM in my phone, and I have the same problem.
1) I tried to install several ROM's:
- Jeff72ROM (v1.30 and v1.32) from: http://www.needrom.com/category/zte/serial-nubia/z11-mini/
- stock ROM from http://4pda.ru/forum/index.php?showtopic=776504&st=0#entry52586301
- And experimental port of CM14 (I can't remember where I found it)
- CUOCO92 from http://blog.grossoshop.net/nubia-z11-mini-rom-gs-by-cuoco92/
- An "official" ROM: NX529J_Z69_EN_NSXPK1JD00K132 from http://www.nubia.com/es/support.php?a=phone&pid=8 (this is the ROM that bricked my phone, I modified it in order to avoid the problem).
To install all these ROM I used TWPR from http://www.androidbrick.com/download/z11-mini-nx529j-twrp-root/
When I dial *#*#4636#*#* on the phone it says that the type of preferred net is WCDMA. It seems to me that these nets are not in use in Europe (I live in Spain). Itried to change that, but I couldn't. Then I applied the patch http://forum.xda-developers.com/showthread.php?t=2394689 but it doesn't work. I also tried to modify the properties in "build.prop" without success. Now I think this is not the problem since all the ROM's have similar properties, in special CUOCO92 that is reported to work in Italy.
What I think it happened:
When I tried to flash the "official" ROM it failed because it tried to write too many files in the "system" partition (I hadn't this problem with any other ROM). Then I realised that my phone was bought in China and this ROM was for the international version, perhaps the international version has a different partition scheme).
What I did is to remove some very easy to install apps (i.e. google maps) in the ROM in order that the remaining apps fit in the partition, but then I made the mistake to activate the option in TWPR of making "rm -rf" instead of a "format". It seems to me that with this option the rm command followed some link to another partition and removed some files that shouldn't be removed, and those files are not in any ROM.
Does anybody think that this makes sense?
What can I do?
nice, super description. i am stuck with my nubia z11 mini, brought from china. installed 1.23, recently updated new 1.36 but there is no google play, other all working perfectly.
Hi,
I have the same problem. Did you find a solution?
Thanks in advance, F.

@jbartolo
I have the NX529J and the option wasn't changed, it was still format. I don't think the problem is related to the partition.
@jbartolo
Any news about your z11?
Did you manage to fix it?
I have the same problem.

I had access to another z11 mini and a played copying partitions from this phone to my phone without success.

Since you can have access to another z11 mini please check these guides

Also you will see more guides in the mentioned site and maybe you can fix your phone. Unfortunately i dont have access to another z11 mini to try. Wish you good luck.
@jbartolo
I did some progress with my phone.
I flash it with the chinese 1.23 rom(its the one in fastboot structure as i understand,a service rom) using Xiaomi's MiFlash tool.
Phone came up with null IMEI'S and MEID. Then i write missing IMEI'S & MEID ,with some tools from the site i mentioned you in my previous post.
So everything is in place now. IMEI'S & MEID.
Now when i dal *#06#* and *#*#4636#*#* i can see Imei's & Meid.
Also i can change the option from WCDMA preferred to other options and stick with them (*#*#4636#*#*) and i can see in phone settings and SIM menu all the options.
Both sim trays read my sim and ask for pin.
In SIM menu, i can search for avalaible carriers but the only problem now is that when i'm trying to connect to my sim carrier unfortunately phone can't register to my carrier.
I'm trying to figure out how to solve this issue.
You can try what i did and maybe you are more lucky than me and can fix your phone.
Hope to hear from you soon and maybe we can share some more ideas.

Yes i know that we need a backup of qnc from another working phone in order to modify it and apply our imei's and meid, but where to find one???
It's difficult to have one as you understand.

You could contact the owner of www.androidbrick.com in case he has one. Or you can ask @jbartolo to provide a backup of his other device. Taking a qcn backup is a pretty simple procedure
@efrai3 Just contacted him again and he was happy to share with me a qcn backup for your device
You can contact him too and ask for one! He will be glad to help!

problem solved: Z11 mini working again
All,
the AndroidBrick method worked.
First I tried it with my own qcn backup but that didn'twork. I received a qcn (Chinese, 64 GB) from AndroidBrick and I followed the repair guide. My Nubia Z11 mini is working again.
The solution for our problem is that you need a qcn backup from a working phone because when you install the wrong rom (international version) the modemst-partions are corrupt.
I'll prepare a backup qcn from my phone (changed IMEI) and I can send it to you.
Send me a mail at [email protected].

Hello Filip,
Would you help me, please? I need the same chinese 64GB qcn file you got from AndroidBrick too!
I followed the same repair guide on AndroidBrick (using a vietnamite qcn file I just download) with no success because when I started restoring the qcn I received a message that My Phone is not compatible and after rebooting ...adviced me 2 times that the update did not success.
I will be happy to give my email address for your (or even other God) help.
Have a nice day and a good way
I bought a Pocophone online, received it, and used it for about a month.
After one month, after Turning it off and back on completely, the wifi and cellular didn't work anymore. (was on MIUI)
I reflashed MIUI from TWRP, thinking it would solve the problem, but now I was stuck :
When you boot up MIUI for the first time (or after reflashing) you need to enter your MIUI account code to go on with the setup process. But that's no use, because with no Wifi or cellular, the phone cant check the password.
I have the IMEI (I don't know for the MAC address) printed on a sticker on the phone's box, but I didn't want to change it myself because I understand that's not completely legal ?... Anyway, I sent it back to client service and waited. They received it, and acknowledged the problem, but as they're an online reseller (big place in my country) they "sent it back to Xiaomi". So I waited again. Now, they're telling me that
Their technicians have denounced the warranty on the grounds that your equipment has been oxidized.
The cost of repairing your device is equivalent to the price of new equipment and has therefore been declared economically irreparable.

I know that's false, but I'm not in a position to tell them anything, so when I get my phone back, I'd like some pointers on how to fix it myself. I'm pretty sure I've got to fix the EFS partition, but don't know how.
I know this is not a hardware problem because the phone is still able to scan, and see and list wifi networks, and the message specifically says there is no IMEI and MAC adress.
Thanks to all of you !

Short & simple method. Flash a custom rom. It will solve your miui account issue. But I don't know if that will solve your wifi issue as well

Yes I tried this when i still had it, but the IMEI and Mac adress are still missing. A phone that cant "phone" is of no use...
Sorry to hear about your loss, how can they say it iodized? Whatever you can use it for a bit of experiments. Do you have any twrp backup if yes you can restore it .if not you can try with any efs backup of nay other device..not sure its possible or not any one here with more knowledge can do this and many in markets can do it too if you can provide them the proof of a legal purchase
I have even worse problem

OK, push that so get scree to enter password so I enter my Mi Account pwd but not work, get message "this device is associated with existing MI Account (186****877). Thiat number is NOT my Mi Account but must be locked inside my phone. I bought this new from Lazada and have no way get at that existing account. So what to do now??

I didnt do to much research, but this looks like it's an official seller. just send it to them for warranty.
Update : Deleted
Phone exchanged and files deleted.
Thank you for the offer but just a bit too chancy and i very much want my Pocophone to be just fully functional phone. The Lazada purchase was very much a legal purchase but the Lazada suppliers are individual shops which may be or not "Official" Xiaomi dealers. I have sent the phone in box and with copy of my receipt to Xiaomi in Bangkok, and hope to have good news from them after New Year. Hope and trust in Xiaomi doing the right thing; Thailand is not strong on customer protection.

Is it possible to use your file and then change the iemi and mac address?
I had to flash to miui 9 in order to get into my phone now I can see my iemi and mac adress are unknown.
Im hoping I have the box still somewhere in order to restore the iemi with some application.
But not sure if there is anything else that can still be broken
lost my imei too i got them writen on the box but i think there is no working way to get them back in the phone

Can you give me efs file? thank you very much.
It's almos a year that I have damaged something and my BlackView BV7000 Pro keep saying "Invalid IMEI" (https://forum.xda-developers.com/android/help/invalid-imei-problem-t3898950).
No app or windows software works, I just managed to restore ONE of the two IMEI, but still having problem with some SIMs.
I finally managed to set my IMEIs, and the way is so simple that I wanna destroy it.
REMEMBER: this guide purpose is sole for restoring your IMEIs due to problems with your phone (like I did formatting all in the memory).
Using a different IMEI is illegal in most countries (if not all countries).
Here you go:
- dial *#*#3646633#*#*
- in Telephony tab scroll down to GPRS option (note: "CDS Information" option doesn't exist in this phone)
- now you can write both your original IMEIs (you found them on the back of the phone or on your phone box)
- reboot
I just find it randomly checking every option. And I used all tools I could find without luck (SP Flash, MTK Tools, IMEI Changer/Restore apps, etc).
Now my problem is fixed.
Enjoy.
Where should I enter the IMEI on GPRS option? thanks for your help man.
Hi, I wanted to change the country code to get native support for call recording. I did this, converted my device to C675 (India) and got the native CallRecording_10.1.0.apk, which is now distributed on all Huawei forums.
1. Download and install the Octoplus Huawei Installer v1.2.2 from https://octoplusbox.com/
2. Pay for a license for 6 months, and you`ll receive the activation code to your email. (P.S. I have nothing to do with this site or the author of the program)
3. Run the program and input the activation code.
4. Follow the instructions on the upper left side of the window, put the smartphone into the On/OFF Factory Mode state (the lowest button on the right in the picture). The program downloads some code from the Internet that is necessary for your smartphone model, and the smartphone turns into a temporary brick until you bring it back to working condition on step 7.
5. On the computer, an unidentified "Other device" USB SER appears in the Device Manager, the device does not respond to anything, does not turn on, only sometimes vibrates when you press different key combinations. Use the device Manager to install huawei com1.0 driver (at the bottom of this message).
6. After that, the program discovers the smartphone, and the "Repair" tab on the right under "Actions" becomes active, with almost all its fields active. In the Country code field, change the country by manually entering the necessary letters. I changed it from ru to in, but you can change to any other region, for example, you can convert the device from China to any European country.
7. Again, click On/OFF Factory Mode, the program flashes the original code to the smartphone, bringing it back to life, it reboots, and data is reset.
8. After the reboot, the smartphone will have a new region code, but the firmware is still from the previous region, so you have to flash (to dload) the firmware of the new region. Another data reset occurs, and you get the device from the new region, with OTA working and so on.
Hello there. Change the country code to make all data on smartphones gone?

2. Pay for a license for 6 months, and you`ll receive the activation code to your email. (P.S. I have nothing to do with this site or the author of the program)
3. Run the program and input the activation code.
4. Follow the instructions on the upper left side of the window, put the smartphone into the On/OFF Factory Mode state (the lowest button on the right in the picture). The program downloads some code from the Internet that is necessary for your smartphone model, and the smartphone turns into a temporary brick until you bring it back to working condition on step 7.
5. On the computer, an unidentified "Other device" USB SER appears in the Device Manager, the device does not respond to anything, does not turn on, only sometimes vibrates when you press different key combinations. Use the device Manager to install huawei com1.0 driver (at the bottom of this message).
6. After that, the program discovers the smartphone, and the "Repair" tab on the right under "Actions" becomes active, with almost all its fields active. In the Country code field, change the country by manually entering the necessary letters. I changed it from ru to in, but you can change to any other region, for example, you can convert the device from China to any European country.
7. Again, click On/OFF Factory Mode, the program flashes the original code to the smartphone, bringing it back to life, it reboots, and data is reset.
8. After the reboot, the smartphone will have a new region code, but the firmware is still from the previous region, so you have to flash (to dload) the firmware of the new region. Another data reset occurs, and you get the device from the new region, with OTA working and so on.

I do not think there is a need to do these steps. Just download and install one of the attached APKs. One is for EMUI 10.1 and the other one is for EMUI 11 and 12 (version number 11.0.0.109).
