Need QCN or /EFS and /Modem backup from RN5 AI/Global to fix no sim issue (M1803E7SG)

Hi all,
I've managed to do a bad restore with TWRP on my RN5AI (M1803E7SG ) and need a new qcn or a backup of the modem and baseband files. If you have either of these, please share it with me
Thanks

i think it's illegal to change imei here in xda but op was able to fix it.

Hello!
Will you be so kind and tell me, is it possible in that way convert redmi note 5 ai to redmi note 5 global but of course without any illegal activities?
I'm just asking is it possible?!
By illegal activities i mean that i don't wish to change IMEI or anything like that, i would just like to convert phone for chinese market in to phone for global market.
Thank You all and again i'm sorry if i'm offending somebody with this question or ask something stupid.

Afaik if someone share their EFS, and you use it to restore it to your phone; you will copy all the imei information from them. So no one is going to share it with you. You are on your own then. Unless there is a method to edit the IMEI, baseband etc to the same value as written on your box.
You also don't want to use other user IMEI as well, just like other don't want to. If there are 2 devices share the same IMEI, it is possible that they can be banned from the network. Or maybe in a very small possibility of the universe, you will deal with the unknown things. If the other doppleganger device do something bad using their cellphone, you can face the trouble too, as you phone has the same IMEI.

Yes!
I know all this!
Of course!
My intention is that I would like to convert this phone from version which is sold in China (aka AI) to Global version which is sold on EU market! That's it and that's all I would like to achieve!
IMEI change is possible, an I will naturally use original IMEI values from the phone and box.
Anyhow, thank you!

I have found "blank" qcm files (without entered IMEI) for restoring!
This is Indonesian MIUI site!
Here is the link for bunch of qcn files!
Use this and save Your self!
Please give is info did you have success!

You can change the IMEI in the qcn file, anyhow this issue has been resolved with the help of another user here. He provided an edited qcn file with my IMEI numbers

That's a true life saver!!! At my previous phone, when we screw up the IMEI, we are on our own. Editing the IMEI only give temporary effect, will be resetted every factory reset. This should give a permanent value.
Do you edit the bluetooth address and wifi mac address as well? Or those address are intact? (0C:98:38:xx:xx:xx something?)
Thanks for trying. IMEI editing topic is a very rare case, and I usually also don't want to deal with (can cause problem later). Should bookmark this in case someday some other users need this.

Both china (AI version) and global has the same hardware. Only India version has different camera setup. All three version can flash the same Global Stable (latest is MIUI 9.5.17.0). I have seen so many buy china/global version and has migrated from one to another without problem. China ROM difference is it doesn't have playstore installed, while Global has it. So to migrate to Global version, simply flash global ROM MIUI 9.5.17.0, no IMEI changes needed. Just remember not to flash the latest MIUI 10 (8.7.9/10), as it has anti rollback protection. As usual, YMMV, DWYOR.

First, let mi thank you for your time, effort and explanations!
Second, here I will go from the end and say that I already know big deal of this you have said to me and that my only reason to do this "operation" of transferring Chinese to Global version is possibility of bootloader lock. As I understand, if one unlock bootloader, like me, to be able to install Global version of ROM, then you stay without lock possibility, and with this without Google Play Store certification.
If I'm wrong here, please tell!
I myself also, don't have time and wish to go in this avanture!
And yes, I don't want to deal with rooting to be able to achieve certification! I wish stock ROM, without anny third party stuff!
Thank you!!!

If what you want to achieve is the device certification, than I don't know exactly the detail. I bought the official version from my country, which is the same as global version, certified. UBL + TWRP + Magisk, still certified (magisk has patched it for me). But some China version (dubbed as RN5 AI), don't have playstore from the beginning. So most likely the phone is uncertified if you choose to use the stock ROM from China. (I don't know the exact detail, let me confirm with other user, takes some time). No other way then, modification is a must. Should flash Global Version, and probably need to TWRP and Magisk to get the certification.

Yeah, seems to me that exactly this is the case i have!
I have bought two phones, one for me and one for my wife, they are both Xiaomi Redmi Note 5 AI and this is China version of the phone, without Google Play Store!
Only difference between them is that my phone is 6/64 Gb and my wife phone is 4/64 Gb!
My phone is Model Number is MEE7S and Global version should be M1803E7SG!
According to hardware list, they are the same, difference is "only" in QCN file and /EFS, /Modem!
I have successfully unlocked bootloader on both phones and i have successfully install on both phones this last Global MIUI verion 9.5.17, without any issue what so ever!
Only, Play Store is Uncertified and when i have tried to again lock bootloader and the install this same global ROM, off course, this is not allowed and to be possible to achieve this, phone must report himself as phone for "Global" market, namely EU.
So, if You can help, please help! :crying:
Again, thank You in advance on everything!

Thank You, but this dosen't solve anything.
This is not intention or direction in which i would like to go (custom ROM).
Few years earlier maybe, but now, i have give up from all of this "games". "Give" me stock ROM and some way to remove bloatware and that's all i need. I don't have ether time or interest for this (life, wife, kids, nature....)
Big help will be "just" a few informations .
1. Is it enough "just" qcn file from M1803E7SG with changed IMEI values from my phone, so that my phone MEE7S would be recognized as M1803E7SG?
2. Is RAM value in ROM universal or it must be exactly specified? I have a phone with 6 Gb RAM and 64 Gb of storage.
3. Must one change /EFS and /Modem partitions accordingly with qcn file (if i'm not mistaken, these partition will be reflashed with new ROM flashing isn't it)?
Thank You all in advance if You can help me with some useful advice!

1. I can't answer that. I know that the M1803E7SG differs from the MEI7S in terms of QCN file, and therefore probably hardware - if you flash a MEI7S QCN on a M1803E7SG, the cell modem won't connect. I would like to try to see if the M1803E7SH qcn can be flashed to the M1803ESG to enable band 28, but I don't know anyone with the H version.
2. Universal - the OS picks up the ram in the kernel.
3. The EFS/Modem folders are overwritten with the QCN file - they are not affected by rom flashing, but can be modifed/written to by TWRP.
Re the .eu version of the rom, it's effectively a universal rom without as much bloatware. It is based on the xiaomi sources and would give you exactly what you're asking for. If you want a stock rom, then this is the closest. If you want to remove the bloatware yourself and use a stock rom, that's fine also. Do what works for you.

Huh!
Here is obviously some type of miscommunication!
My phone Model Number is MEE7S!
I would like to "convert" him to Model Number M1803E7SG which is counterpart of the same phone, "just" Global version!
These are hardware identical phones except enabled bands!!!
And yes, Thank You so much for this information about RAM values, this is excellent!
Also, thank You on such a quick reply i really appreciate this!!! :highfive:

As for the conversion, they are not necessarily the same hardware, the Chinese version MEE7s has fewer bands. Be careful.

Yes, i think that this is main difference between these two phones.
All other is exactly the same, same cameras, same sensors, same display, everything is the same!
And yes, as i have understand, there is no 6 Gb RAM device for global market, only Chinese!
Again, thank You on kind words and understanding, these days it's hard to meet somebody who is not immediately "on the edge" and who is ready to talk and elaborate not to judge!

You have actually got the answer you need. But just to report back from the small survey I have made in the other forum. 5 of the users who bought the China version, all got uncertified. But one user change to AEX and use some ro.build.fingerprint from the Global version, got the certified status (and cts profile true). The other have flash to 9.5.17.0, rooted using magisk, playstore still uncertified, but magisk show cts profile true, basic integrity true. Don't know why still uncertified, maybe the playstore cache the status from before the patch by magisk. So to achieve the certified, no other way without modification. Editing build.prop, or using magisk module is a must.

Now, there is definitely some strange issues here.
I think that maybe solution is to edit qcn file and make this phone Global version. Then, bootloader can be locked and Global ROM can be installed. As i understand, later google policy is that bootloader must be locked and in that way Store will be certified, i hope.
Now, as i understand, this can be done in two ways. One will be to make qcn backup from phone and then edit this backup so that phone model number could be changed, and then this qcn backup, with all other values intact, flash back to phone. Other is to find from someone qcn backup, who has this Global phone, and then in this backup change IMEI and all oher values to correspond all values from my phone.
Now, what's you opinion about all of this?
And again, thank You!!!

I was the one who sent OP with the global qcn file with his/her original imei's. QCN means QUALCOMM CALIBRATION NETWORK file. It only contains your imei and the signal bands your phone should connect to. There is no way you can change model number on the qcn file alone. Sometimes flashing different qcn from a different device will make the phone's baseband unknown.
I think the model number for xiaomi is embedded on the motherboard.

Bootloader status on Chinese device

Im waiting for my device to be shipped. The vendor sells a Chinese Whyred then installs global rom with play store. Does that mean the bootloader has already been unlocked? Can i use my Mi account with privileges to unlock it straight away or have to wait the 15 days?

Why didn't you just get a Global Version?

It says "China version global rom" quite a big seller on AliExpress. So I assume that's what they do. I don't mind, I was just wondering about the bootloader with all this. I wanted the 6gb machine which they didn't have in the international version

Yes it hard to get 64gb Global version as not many resellers stock it.

Are you not worried about the lack of Band 20 for LTE use there!
Your device will probably be fine in cities, but out in the country you won't get it.
Having Global rom, won't unlock more bands because it is hardware dependent.

Lol I know this. I'm not really bothered. I have global Redmi note 4 with band 20 but 4G still weak with my provider. I rarely use data and with oreo I tend to keep it on GSM/WCDMA to save battery
Edit. Well I've read around and about, apparently relocking the bootloader on Chinese device will definitely result in soft brick (which is music to my ears as I want it unlocked) except the guy via aliexpress chat said after flashing Global rom they relock the bootloader ><

Some partner has an account with permission to open bootloader? it has been reset and I have to wait 360 again

Q about 6GB 128GB version

Is the 6GB 128GB version exclusive to China?
All the Xiaomi websites that started revealing the Mi MAX 3 on their front page (which should be the international version) list the phone's spec with 4GB 64GB only.
If it's China exclusive will we be able to install the Global ROM when officially released on it as it will be specific to the 4GB 64GB version?
Thanks in advance.

I have a 6/128gb model here in the U.S. - the hardware should actually be identical aside from storage sizes, and I've had no trouble flashing anything. I can't imagine there would be any reason you couldn't flash to your firmware of choice as long as your bootloader is unlocked.

Thank you very much for your reply.
However, that is the case now as there is no Global Firmware officially available, but how if when this Global Firmware was released and intended only for the 4GB 64GB it might cause problems if it was installed on the 6GB 128GB if it was going to address the phone's memory sectors differently than the 4GB 64GB memory sectors.
The main question here is: are there two different firmwares for both versions or it's only one universal firmware that is used for both versions with different memory capacity?

Same SoC, same code name, RAM and storage size doesn't mather so same firmware/rom for both...
Have you seen different roms listed for both versions anywhere?

We can actually take this a step further. Since the redmi note 5/pro has basically the same internals as the mi max 3(less USB type c, larger screen), how hard is it to modify the Note 5 pros global stable rom to accommodate the mi max 3? The only reason for not going this route is to go directly to Android 9(Pie) development. My two cents.

If the two versions of the phone were different enough to require different firmwares, then they would have different code names - signifying what firmware to use for a device is one of the functions of a code name. Since they are both simply "nitrogen," this means they should take identical firmware. I've had a lot of phones and modded them all, and spend quite a bit of time reading forums for devices I don't own but am interested in, and if the two versions take different firmwares despite having the same code name then this will be the very first time I've heard of it happening. I am 99.9% sure that both phones will take the same firmware.

Yes, 6gb/128gb is a China exclusive and won't be released globally. same goes for blue variant. Any 6/128 "global" edition is likely to be a fake rom with forced unlocked bootloader. So u guys should beware.

So, the important question now, can we re-lock the bootloader on the 6GB/128GB China version after installing the official global firmware on it? because some have mentioned that the phone returns itself to unlocked state again after doing this.

Thank you.

I have waited so long for the 128GB Global Version and am starting to warder if it will truly come.
Please would you advise me to buy the Global ROM or still wait for the Global version as am not sure it will Come?

Coming from a 6gb/128gb owner: just buy the damn thing if you want it.
I personally don't regret it, saved myself the wait for the bootloader unlock, and would have installed Xiaomi.eu anyway, even if I had went for the "global" version.
Last but not least: there are no modem differences between the global and chinese model, so why wait if you end up getting the same band support anyway?

Agreed 100 % from a 6gb/128gb owner on 8.8.9 xiaomi.eu.

6/128 Gb Gold version here as well, on the so called unofficial unlocked 9.6.4.0 dodgy global rom. Been using it , giving it a hammering over the last couple of weeks.Fast and stable...no bugs to report.Not bothered in trying to update it.Everything seems to be doing what i want of it.

There will not be a Global Version of the 6GB/128GB variant as the phone is already available on the Xiaomi Global website and on the spec only listed is the 4GB/64GB variant.
It's all up to you to decide on which version you want, keeping in mind a couple of things:
First, no need to wait for a Global Version of the 6GB/128GB variant as it's not coming ever.
Second, there is no difference between both variants except for the memory difference (obviously) and how would you like your bootloader be locked or unlocked (with the Chinese version to stay on locked bootloader you'll have to remain on the Chinese Firmware pathway but if you want to go the EUMIUI or IMUI Global you have to unlock the bootloader, however, with the Global Version you can have the bootloader locked while you are on the official Global ROM with OTA updates working normally)

Hi
Good day sir
Please I need to understand you properly on this, am a novice here and am sorry for the way I will put my questions as below.
If I buy the Chinese version from aliexpress 6gb/128gb,would I get regular MIUI update from xiaomi and also newer android update without any tweak on the ROM?
The thing there is am not familiar with locked and unlocked bootloader as am scared of bricking the device at any attempt.
I just want to buy and enjoy my device without any tweak on rom
Also, I do read that the Chinese version, has mix up of language when tunned to English (has English and Chinese writing). How true is it?
Please I need answers before I make an order.
Thanks

If you are not going to modify your phones' firmware and stay on the original firmware then you'll be good to go and you will get regular OTA updates from the official Xiaomi servers but keep in mind that this would be the Chinese firmware pathway all the time for you.
The Chinese firmware has English language but as you said there are some here and there mix up but it will not interfere with your daily use of the device but it's there (you'll find some naming in the menu in Chinese)
The other thing, is that the Chinese version doesn't have Google Play or any other Google services but you can install these easily from an app that is available on a Chinese app store pre-installed on the Chinese version.
So, if you are ok with all of the above you can get the 6GB/128GB version but if you are not feeling much comfortable of Chinese lettering here and there and some Chinese apps on your device then go with the 4GB/64GB version.
By the way, there will not be much difference of performance between the 2 devices (if any at all) if you are wondering about that and for the storage the device has a Micro SD slot and you can have all the storage that you want with that.

Hi,
I will try to make things more clear : ....
I have ordered and received from a known Chinese internet site
(not my first order with them)
"[Official Global ROM]Xiaomi Mi Max 3 6.9 Inch 4G LTE Smartphone Snapdragon 636 6GB 128GB 12.0MP+5.0MP Dual Rear Cameras Android 8.1 5500mAh Type-C OTG Touch ID - Black:"
Before shipping i have inquired :
" Is the "official Global Rom" genuine by Xiaomi or flashed by ********* ??? is the box original sealed or open ???"
The answer was :
"Dear friend,
Thanks for your inquiry
Sorry for the late reply
this item is Official Global ROM by xiaomi
it is packed by original sealed box
please do not worry
Hope you enjoy your shipping!
Best regards
The Phone was received relatively fast @ 9th. October very nice Mi Max 3 very responsive with "MIUI Global 9.x.x.x....."
Few days later got an OTA "UPDATE Alert" to MIUI Global 10.0.1.0 Stable (OEDMIFH)
The update performed in few minutes all looks good up to i found on the XDA site
The link to "Mi Product Authentication" :
https://www.mi.com/en/verify/#/en/tab/imei
I have clicked the IMEI and found this :
小米Max3 全网通版 6GB内存 黑色 128GB
Thank you for choosing Xiaomi!
However, the device you purchased is not an official global version and user experience may be affected. Next time, please purchase the official global version of the device through officially authorized channels.

Started searching 6/128 Global found out there no such version on the market ....
Opened a dispute on Pay Pal
Waiting for Answers ......

You should never listen to a vendor regarding this information without thorough research. That's why Xiaomi implemented the new 720 hour official bootloader unlock.

The Rom , like mine is official.The method they used was unofficial.As there is no 128gb International version phone in existence. You will always get a Chinese version 128gb phone, as seen when you check the IMEI software link. With the "Official rom" loaded by the person you purchased it from.
To do that, they had to unwrap the Chinese version phone, Install the "Official rom" and then send it to you.What they did wrong was state to you that the phone was in a sealed box.If you are concerned with having a Chinese version of the phone, i would suggest you try to return it and downgrade to the Official 64gb International version phone in a sealed box with the same software on board.
I Personally more than happy with my 128GB Chinese phone with the International Rom loaded.

I wouldn't have opened that dispute TBH.
The Chinese 6gb / 128gb model is still the best one on the market, and let's face it: you would have installed the Xiaomi.eu ROM on the "official" global version anyway, just to get theme support and rid of the ads.

Is a true international version available with working modem out of the box ??

Hi, want to buy one Mi Max 3 to use in usa tmobile !
Can somebody confirm there its a 100% true international version of the phone that has a original Xiaomi international firmware that dont have connectivity problem with bad modem.?? And that gonna receive ota updates and updating it wont brick the device ??
I'm asking because its so confusing that some people say there its not true global version (only chinese with shop rom, and fake global sticker in box)
I only want to buy if works out of the box without problem !
Dont want to have to mess with a brand new phone to try to make it work !
Please let me know, thank you

This can only apply to people who purchased the global version that has V9.6.7.0.OEDMIFD installed, as we know that 9.6.6.0 is broken

there isnt any working modem on 9.6.6.0.OEDMIFD
I tried the default modem, 9.6.12.0 (china modem), 8.8.30, 8.9.6, 8.9.13, 9.6.6.0 (china modem)
I tried changing the vendor partition which broke even more stuff.
Maybe @nijel8 havent checked under ground (parking lots), in door buildings, and more which make the signal so weak.
also there is no LTE/LTE+ on the 9.6.6.0.OEDMIFD
We need someone with the un-released 9.6.7.0.OEDMIFD to confirm this

Don't be so sure as we don't know 9.6.6.0 is broken. You've already said 9.6.4.0 is fake and that wasn't true.
You installation of 9.6.6.0 doesn't proof anything.
We know for sure many times problems are fixed by fastboot rom nad we don't have global fastboot rom released yet to test.
Yes, I haven't tested mine enough to know for sure it runs fine under different conditions so I will not say it has no problems, we've had enough rumors spread around... So let's just leave it to people who have more to say...

I'm on 9.6.6.0 for a week now as a daily driver, no problem at all. So, afaik, 9.6.6.0 is not broken.

Global SKU of the phone is not available yet.
I'd suggest waiting if you want modems to work properly - possibly also extra bands and NFC.

Can a phone with a metal back do NFC? Just asking...

I'm not sure if you are aware what are you actually using. The phone does not have NFC. https://www.gsmarena.com/xiaomi_mi_max_3-8963.php That is one of its weak point.
You cannot enable something by software if the hardware is missing.

I'm aware the version currently doesn't, and of course it can't be enabled without the hardware.
However, I was told by a retailer (who are selling 'global' units) that the true global version was not available yet, would be a distinct hardware version, and that it may carry both extra bands and NFC.
"I'm not sure if you aware" that other global versions of Chinese phones have added both an NFC reader and additional bands? It is not unlikely in this case.
I had asked them about the likelihood of a Max 3 Pro coming soon (and with NFC) as Malyasian / Indian e-tailers had re-added pre-orders for the Pro, with October expected date. They said they didn't know, but gave the above information about the global Max 3.

Well I did read about the device quite a bit but I haven't seen anywhere the global version would have NFC. I doubt Xiaomi would change the hardware in the global version. M3Pro on the other hand as you say may come with that but its up in the air yet...

It's rare that Chinese brands release any information ahead of availability of global SKUs, even if the hardware differs (which it not infrequently does).
We'll see.
The Max 3 is apparently among those devices that'll be officially available in European markets .. that makes it a lot more likely that bands and NFC will be added, as there have been in other phones.

I didn't think that there was any difference between the original Chinese variant and the International/Global variant which they began selling in Hong Kong, Singapore and the Philippines last week, but I was wrong. My Chinese Mi Max 3 arrived from tradingshenzhen with an unlocked bootloader and xiaomi.eu flashed as I had requested, and with xiaomi.eu 8.8.9 it works great. But a friend recently came home with a Max 3 purchased in the Philippines which is running v9.6.7.0.OEDMIFD (Global). When he goes to the Mi verification web site and enters his IMEI it says "you have a valid International Version". When I go to the site and enter my IMEI it says "you do not have a valid International Version and may encounter difficulties - please purchase from official distribution channels in the future".

thanks for the reply, so it comes down to luck, hit or miss with 9.6.6.0 and i'm better off waiting for xiaomi to put a fixed version in the official rom website ? (As of now no official firmware to download there for this device !)

Ok, I am getting irritated by you already...
Don't give your opinion on something you don't completely understand. As I said your installation procedure is so lame I don't even know how to say it without offending you. Believe me that is not my intention...
First you don't have global version and the OP question is specifically for that one.
Second you don't have fastboot global rom to begin with. There are so much more to the rom than what is it in the recovery zip. Otherwise Xiaomi won't be releasing both.
Third how do you know if Xiaomi didn't place some restrictions preventing Chinese devices running Global rom properly hence your problems...
So until you flash fastboot Global rom or better yet for this OP get global version try to not spread false information.
Peace...

No official yet?

Can I Install Global Version L29 on Chinese Version?

Hi guys,
I'm thinking about buying a chinese version of the mate 20x for cheap, much cheaper than the global version. Was wondering if its possible to buy it and then install the L29 global rom. Is this possible? If so how?
.

Not sure if possible, but i dont recommend to change the original rom.

Appreciate the reply. But since youre not sure, does anyone know if its still possible to do this?

From what I understand (reading this forum), this requires unlocked bootloader and root.

Hi.. thanks for the reply. How do I unlock the bootloader?

Buy Chinese version with global rom. It raises price just about 35 to 50 dollars.

But thats the problem I want to avoid. I want to buy the chinese version without having to pay for the global rom so that i can install the global rom myself.

I will save you some trouble. I made the mistake of buying the Chinese version because I assumed the bootloader could be unlocked and the phone could be flashed. The answer to your question is, "no - you cannot root or flash the Mate 20 X as at this time".
Huawei has locked all bootloaders for all their devices and are no longer offering unlock codes. I have been unsuccessful in unlocking my EVR-AL00.
There are a few threads in this forum and there are developers looking for a workaround but there are none at this time.

I wanted to post a quick follow-up on my previous post. The Mate 20 X Chinese version is the first non-root phone I have owned in more than 10+ years. I will say, unlike my Samsung and OnePlus phones I have not found a need for root beyond changing the default launcher. The phone is customized so you can manage DPI settings (in and outside developer mode), auto launch/keep apps running in the background and even includes a good equalizer. If you have any specific questions about the Chinese model of the EVR-AL00 then feel free to PM me. I'm happy to try answering questions.

Hi dogatemycomputer,
Appreciate the heads up. But regarding rooting the mate 20x, there are threads here that show that you can root it and flash twrp. Am I missing something?
.

Yes.
Regarding XDA’s stance on Huawei’s decision to stop bootloader unlocking
Back in April, Huawei’s form to request a bootloader unlock code mysteriously disappeared. Late May, the form returned but with a warning that the service would no longer work after 60 days. As promised, Huawei’s form is no longer available, meaning it’s no longer possible to unlock the bootloader of Huawei or Honor devices. This has obviously been disappointing to many users on our forums, but it’s been especially disappointing for us, the XDA Portal team.
https://www.xda-developers.com/xda-huawei-decision-stop-bootloader-unlocking/amp/
Basically you could unlock the bootloader until May when Huewei decided you could no longer.

If you truly had read and understood threads about this, you'd know that unlocking the bootloader is no longer possible. Huawei shut this down, unfortunately.
I researched this before purchasing, as I too wanted the least expensive version which allowed changing the default launcher. The only solution at this point is a new L29, or a used AL00 that has root. Shame that if we want to change the launcher we're limited to the 6/128 version.

1. Broken Google Location History & Sharing
2. No access to EMUI 10 beta

I use the Chinese version and there are some minor differences between the Global and Chinese version but the Chinese version has worked well for me.
Some Google services do not work. The two I have found are OK GOOGLE (always listening) and location sharing via Google Maps.
Outside of these 2 limitations I have not found a difference between the stock Chinese and Global versions. I have been very happy with my Mate 20 X and I have not found a reason to root the phone.

Thanks for your input. I think rooting may be overrated unless you install roms. But even then most roms have issues which convinces me personally to stick with stock.
.

I have no issues with Ok Google or location sharing via Google Maps. My AL00 is on Emui 10.0 & works perfectly, i’m in Europe btw. Of course, the big difference is when factory restoring must install manually the google apps like Play Store, Maps, Google Photos, Chrome, and so on. Otherwise i see no difference between global and chinese version.

solution chinese to global rom
for all those looking for solution to change firmware from Chinese to global, search on Facebook for ministryofsolutions. he can donthe job at minimum costs. had mine changed today, very happy.
