Realme 6 - Global Version Firmware Update - Realme 6 Questions & Answers

Hey everyone. I'm a proud new owner of a Realme 6. I bought it as being a global version (model RMX2001) 4/128GB.
I updated but found out that the firmware version was RMX2001_11.B.33. I think it must be a Russian Version even though I bought it through a spanish online retailer, since the box comes in russian.
I checked and there was a version for the Indian Region (RMX2001_11.B.37)with the same changelog as the one for the European Region (RMX2001_11.B.34). I downloaded the firmware for the European Region (RMX2001_11.B.34) and updated through the recovery mode.
Can someone explain to me what are the consequences of doing such a thing since I updated a RMX2001 model with a RMX2001EU model? Also, does this mean that from now on I'll get the OTA updates for the RMX2001EU model, European Region or only the ones for the RMX2001 model, whatever region I got?
Any other input regarding this subject is deeply appreciated. I'm curious more than anything. Thanks!

my phone is also a eu model, and didnt get the latest update to.
what i did is realme.com india region/market and find the o.zip RMX2001_11.B.37 and installed
everything working just fine for me. so i think all those phones are just the same..

I got my phone from amazon spain. I live in switzerland.
The latest OTA was B.30 for me. I downloaded B.37 from Realme Site and also updated via recovery.
Everything works however.
The hardware is definitely the same in all phones. But somethings still different. Some phones are able to unlock bootloader (india models I think) while EU models cant.

I definitely updated my Global Version with the EU Firmware. And in the settings I have the RMX2001_11.B.34 Version (which is actually the same as the RMX2001_11.B.37 according to the changelog, but not the size). I prefer the EU version since it may have less bloatware and ads due to the European restrictions. Also, I live in Portugal so I think it's better to use the EU version, unless a more recent version is available.

That's the strange part. It seems all roms are interchangeable, but then, what are the differences? Actually, how can one know what is their region? I say mine must be from Russia due to the text in the box and it also had a russian app installed. I updated with the EU rom and the model still is RMX2001 (not RMX2001EU), but the version is RMX2001_11.B.34. So I used a RMX2001EU_11.B.34 rom and it updated to the RMX2001_11.B.34 (missing the EU part). Furthermore, all package names and MD5 checksum are the same, when compared. Therefore, I actually think it is all the same and one can use any rom to update.

I didnt even realize that I downloaded the "non EU" rom from the india site. I honestly dont know if I had an EU rom when I first booted up my phone. I dont remember seeing EU in the OTA settings. However the latest OTA for me was the b.30, which is why I updated to b.37 manually because i thought higher number = latest update
Yeah its very weird. I only know that there is a global and an india version of the phone. We definitely have the global one or else we would have trouble with the 4g signal (or at least me here in switzerland)
EDIT: I think im a little confused now. I think you mean you had the RMX2001EU_11.A.34 (with the A)
There is A and B. Probably A for global and B for india

on 4pda forum some members mention that RU firmware supports "call recording", in all other roms(incl. EU) thats restricted due legal laws

You're right. I updated with the RMX2001EU_11.A.34 firmware version. Actually, I must have updated to the RMX2001_11.B.33 via OTA and then by updating with the RMX2001EU_11.B.34, I ended up with the build number RMX2001_11.A.34. At least that's what shows up.
I honestly think we can use whichever we want that any will work. I'll stick to the EU versions.

So supposedly, you downgraded... This is definitely weird! ahah As long as nothing is bricked, it's fine. At least we know that we can update with any version.

Also, on a separate note, does anyone know how to check volte and vowifi? Or enable it?

Well, both versions are supposed to bring the very same updates. I'd rather wanted to be on EU version too, even if its just for the file name and nothing else lol. My phone probably shipped with the A version and I mistakenly updated it to B

if you look at the changelog it is the same for both versions

Hi. I want to buy a realme 6 in Spain but I need to record calls. The EU version does not allow to record calls, but the Indian Rom does include call recording. I have read that you installed the Indian version, can you see if you have the option to record calls?
To change rom is just install? There is no need to open bootloader, right? Can the Indian Rom be used in any country? I want to use in Spain
Thank you very much.

But I think it is only necessary to change the EU rom to a RU or Indian Rom. Do I need to unlock bootloader just to switch to a Rom from another country? It's strange...

I updated but found out that the firmware version was RMX2001_11.A.38.

Better to switch to a chinese firmware than to stay with an Indian or US firmware

Like the title say is it better chinese firmware for future updates, hearing about LeEco problems in the US and India. I have a Le Max 2 had the sellers firmware on it the one without the system update. I was able to install the Indian one 5.8.19S. The way I see this only the chinese firmware is up to 5.9 and have a better chance to get Nougat. Thanks.
You don't have chance to get Nougat from the stock firmware either India or Chinese stock.
you should stick on whatever stock firmware you already have, or lineage OS for the latest android with buggies
no I flashed tablets and smartphones for ages but now I wont to stick with stock firmware. I read that LeEco are working on Nougat updates but I thing the chinese will possibly have it or if not I will update to the chinese the 5.9.2xS. thanks
2 questions
1. dose my warranty voide
2. will chinese version work same as indian version

2. Yes, same as Indian but without Google apps though you can install manually.

Emui 9, Android 9 DOWNLOAD for P10, P10 Plus, Honor 9, Mate 9 - open beta update

https://www.getdroidtips.com/download-android-9-0-pie-beta-for-huawei/
You're welcome
Just notice:
The regions for the P10 firmware are limited to Latin America, Argentina und China.
Don't flash the firmware before rebranding your phone! It's also possible that you can't use the mobile network in your country with a firmware from a different region.
The Chinese versions, AL00 and TL00 don't have Google services including play store installed.
So, don't install anything without knowing what you do
I still wait for C432E1R1P8 and try flash to Pie Beta ??*

Do you have to rebrand first? What happens if you don't rebrand before flashing this?
I read that it will make you region C900 but nobody said if C900 is a problem. It's just the international version.
So you could still use the phone on region c900 right?
Possibly single/dual sim will be affected?
I don't know if it works different with pie, but my last information is, that you can't install it. The recover, even the NoCheck version, checks the oeminfo partition first. I also never heard about C900 VTR models, the international version without branding is C432, while this code is for France / Western Europe on older devices.
It can happen, that your phone shows developer version. Then you'll have some problems to rebrand to a real version with pie, because there are no oeminfo files for pie, yet.
If your phone is in developer mode, you're able to use it as normal but you won't be able to update via OTA or even with methods like HWOTA8.
Is it worth to upgrade to Android Pie 9.0 ? Does anybody has some experience with it ? I read somewhere that 9.0 works much more with Ai algorithms. Like prediction, etc. Beside that Ai for OS usability i am more curios if / interested in:
- if it uses less RAM memory
- if it use less battery power
- if it has a performance boost overall
If all of this points are opposite on 9.0 , i don´t see any benefits in it.

What if we rebrand to version C605 which is this 9.0 firmware region then flash the rom.
Theoretically if this is the first firmware available in europe for Pie then we should get an update of final version soon after right?
So won't need to rebrand later and by that time Pie will be full release??
The main concern is to make sure bootloader code does not change during rebranding because then we're stuck.

C605 is for Latin America / Columbia. If they use other network frequencies than Europe and Huawei specified those frequencies in the firmwares than you're not able to use it here.
But yes, you should be able to rebrand to C605 by flashing the correct oeminfo. Rebrand on Oreo first before you update to Pie.
The bootloader code shouldn't change because of rebranding, it's hard coded into the bootloader and Huawei uses serial, model number (not region) and IMEI to make the code, those information won't change.
If you'll get updates while using a phone in a different region as the firmware says, isn't clearly, yet. Huaweis update plitics are a miracle, some guys still stuck on Nougat, some guys are getting the newest updates.
Update manually if you want to be up to date.
Guys I'm from Argentina and want to install emui 9. Tried to move to SD but fat32 has 4gb files limit. Is there any way to install it from internal storage?
Format SD to NTSF
So, did anybody from Europe rebranded and got it working with gsm properly? If so, to which region did u rebranded? Thank you.
Good evening to everyone. Is there a twrp for p 10 EMUI 9? Thank you

E-label location of FCC ID for H850?

Hi Folks,
According to the documentation I have, the FCC ID should able to be located by navigating to the Regulatory & safety item within Settings. There appears to be 2 options for locating this item. It is supposed to be displayed either under the General tab or in the About phone category of Settings.
However, it is not to be seen. Even doing a search doesn't reveal it.
The phone was new in a sealed box and has Android 7.0 installed with an Android security patch level of 1 November 2016.
Has anyone else had this problem and was able to solve it it?
Thanks!!
I can see the setting exactly where you said on my G5, with Android 8. Have you tried updating the phone to Oreo to see if you can get the info you need? Don't expect much, it only shows very basic info, at least on the OPEN_EU version.

Thanks!! for the feedback.
Very interesting. Are you the original owner of your phone? If so, did it already have Oreo installed when you bought it? The documentation I previously referred to was from 2016 but Oreo was released in August 2017.
The LG SN & Carrier & Country Check, provided by IMEI.info, indicates it is an Israel variant and is associated with a Carrier in Israel (Carrier Code: ISR, Carrier: ISRAEL) which does not seem to make sense given that the phone was in a Sealed Box and supposed to be Unlocked. The same report also indicates it as having a Firmware File of H85030e_00_OPEN_IL_OP_0206.kdz and Firmware Version of H85030E_00 which indicates Android 8.
The list of Firmware, on the LG-ROMs website, also correlates with the Firmware File mentioned above.
Download LG Firmware for LG G5 LGH850 Android 8.x Oreo kdz stock ISR Rom
Download Android 8.x Oreo KDZ stock firmware for download with direct link
lg-roms.com
However, I'm not sure if the phone, I have, is a UK or Israel variant. The preselected Language was English. Preinstalled apps, such as Evernote, Facebook & Instagram, correlate with UK and Israel variants according to the respective User Guides. If it was an Israel variant, why wasn't the preselected language Hebrew one would be inclined to ask. The Israel User Guide contains both Hebrew and English versions.
After running an HDMI Connectivity check, the next step is to try an OTA (Over-The-Air) Update. The phone is in Oz. Would there be any problems attempting an OTA update for a phone that is not in its original region?
Does your phone correlate to the details on the following page which indicates a Region of EEE?

I'm making an educated guess that the "EEO", in the File name H85030e_00_EEO_GB_OP_1121.kdz, refers to the OPEN_EU version that you mentioned.
Thanks again.

I was not the original owner: I bought it second hand with Marshmallow installed, then I've upgraded to Nougat and then Oreo. I really don't remember how the FCC menu used to look on previous OS versions.

My neighbour bought a Huawei Phone online, and it was an Israelian variant as well. It was a new untouched phone, and I'm quite sure it didn't have Hebrew as default language on the first boot. It works with no problems in Italy. I think that the phone tries to guess the language to be used according to the SIM card: I have a couple of tablets made for the Italian Market, with no SIM card inside, that on first boot are set on English.

As long as you are sure about the model (H850), attempting an OTA or flashing a different variant for the same model is totally fine. Even in the case there are some incompatibilities between the Israelian carriers settings in the firmware and the carriers in the UK, they would be minor issues, such as the NTCODE error. Moreover, you would still be able to flash again a different variant using LGUP if you're not satisfied with the one you have.
EEO_GB by the way is not the OPEN_EU variant, that is called exactly OPEN_EU. I suppose that EEO_GB might be related to EE carrier in Britain.

It's definitely an H850.
Not looking to Flash any ROMs.
The phone is in Oz (Australia).
Would it be best to do the OTA update without a Local SIM card and just use a Wi-Fi connection to the Internet?
Can an "NTCODE error" happen after an OTA update?
Thanks!! again.

If you update the phone through an OTA update, the location shouldn't matter for the update process to complete. The phone will download the latest update available for its region. As the phone is in Australia and it's an Israelian variant, it will receive an Israelian update. So, as long as you use OTA updates, NTCODE error shouldn't happen. But don't worry, even if it happened, it would be just an annoyance, as it shows just once when you start the phone, but wouldn't affect the usage.

Galaxy s21 not receiving updates

I have a Galaxy s21 olympic edition with number SM-G991Q and i am not receiving montly updates. The last update was the August 2021 patch and was installed on August 30th.
Also smart switch on Windows is not detecting Any new updates.
I tried to reset the device without luck getting new updates.
Does anybody has the same problems with the Galaxy s21 SM-G991Q not receiving updates?
I have this phone too, I also only got the August security update.
Don't worry, they probably lost their update schedule before switching to Android 12. I got updates yesterday for SM-G9910.
I have the same phone and find it odd that it doesn't show up on sammobile or anywhere else.
Does anyone know where to find original firmwares for it?
I have too G991Q and I need flash to XAA because I need BAND 20 LTE my country help me pls or altwrnative stock ROM?

Well on november 8th i finally got the october 2021 update. Hopefully the android 12 update will follow zoon
I have a question about the G991Q, did any of you get the ESIM to work yet? It is currently software locked - in theory it should have it because it is a Snapdragon chip
Do you have Android 12 on G991Q already? Im checking every day but still no luck Should I install non olympic rom? Will that work? Thanks
@Corbik
This particular variant has yet to receive the stable One UI 4/Android 12 update.
@jussy
See here; the model number of this variant is SM-G991Q and the CSC is SJP. At the time of posting this, the latest available firmware version is G991QOPU1AUJ2.
my version is g9910 and still no update to android 12.
last version a11 octuber security update....
whats happend....
What standard version would be closest to G991Q? I tried to flash U1 ROM but no luck
Friends i'm also with the SM-G991Q olympic version.. I really need to switch to CSC from ZTO, to try to use VOLTE and WIFI CALLING from my operator in my country, Brazil!
Can someone please help me change CSC to ZTO ? I tried the tutorial above, but it doesn't open anything when typing the codes, were you able to change? I saw that it only works on android 10. but we are on android 11.
I saw that you have the option to change CSC ANDROID 11 via Samkey, but I believe it still doesn't have support for our SM-G991Q device.

What standard version would be closest to G991Q? I tried to flash U1 ROM but no luck

Have you tried switching to another S21 variant's ROM with Snapdragon 888? it worked out ?
If it doesn't work, I think I found our ROM to perform restoration via ODIN, in brink event:

Yes I tried the U1 version since it should be US version with Snapdragon888.
That ROM you found, based on the numbers is exactly what is in my phone now.
I think I will just wait some more time to get official Android 12 update, hopefully our special version wont be forgotten
But If somebody know which ROM would also work for SM-G991Q and ideally would also support all languages and features (esim for example) please share

Question Flashing UK version of XQ-BC52 on TW XQ-BC72 (.oem files for Volte & Wifi Calling)

Hi Everyone,
Can anyone help me with process for flashing UK version firmware of XQ-BC52 on Taiwan version of XQ-BC72. I need to know which firmware files such as ".ta" or any other files to be removed from firmware folder before flashing. The UK or US customization versions supports volte and Wifi calling in my country.
Currently the Taiwan firmware version is at 61.0.A.23.20 (android 11) and UK firmware version is at 61.1.A.2.211 (android 12)
Can I just flash the .oem files of UK firmware to TW firmware?. But, since device firmware versions are different, flashing may fail and corrupt the device. Can you confirm if this is safe to flash?.
Request your help!

I think yes but r u sure that customized UK fw supports voLTE and WIFI calling? the switches are in the settings? because I have the same model but with eea customized and have no volte or/and vowifi switches.... My carrier supports them btw
I've been told the customised SEA also has Volte and VoWifi wnabled, but I never got any joy out of it when I flashed it into my HK BC72 device. I have tried the previous firmware revision of the UK one, but nothing there either.

So if I flash it to my XQ-BC52 will it affect anything? I don't want to lose anything, but I want to use volte I have no idea why it isn't enabled when all of the carriers on my country support it
I would first update it to the newest TW Firmware and check if it works (so you can update, without loosing personal data).
If it still doesn't work, I would try the HK firmware, because of Over-The-Air–Updates (OTA). I have VoLTE and VoWifi in Switzerland with this firmware.
If it still doesn't work, try the BC-52 firmwares (but you loose OTA Updates).
Please just check after flashing a new firmware if you have the functions. If it works, first do a repair with Sony Companion before starting to install everything (like apps, files....). This makes a clean install and avoids a lot potential of failures/problems.
I bought the phone in Etoren and it is the model XQ-BC72, I live in the UK, and the update I received via OTA and is installed is 61.1.A.2.211 release-keys. you shouldn't, I guess Sony recognizes you're in the UK and installs the correct one

You won't lose your data if you explicitly tell it not to clear userdata off your phone, if that's what you mean. If, however, you're referring to certain functionalities I sometime hear of getting lost, then I myself haven't noticed such with all versions of firmware I have tried out so far.

I've yet to do a clean install, the way you have described it. I guess I'll do it just like that when I've given up on trying to activate VoLTE and VoWifi on my phone. It's interesting that your Hong Kong phone has that function over there. I suppose there is some substance in Sony's insistence that the one's network provider be engaged as well.
I was considering getting the Xperia 1 IV which would be a nice upgrade from my Xperia 1 II but with volte not working it would push me away. I managed to get it working on my Xperia 1 II by simply flashing SEA firmware. It was straight forward and has worked flawlessly with OTA updates. It doesn't look like the Xperia 1 IV will work that way. Even if I was to flash SEA firmware it looks like volte still wouldn't work. Come on Sony sort this problem out
