Installing global ROM on Xiaomi mi 6

Hi experts. I have bought mi 6 from China which came with a Chinese ROM, to which I have now installed GooglePlay somehow. I now want to install the global ROM on it but there seems to be a problem. I have tried installing the available global ROM via the updater app on the phone (as mentioned on the website) but it won't allow me because the global ROM version is older than the present Chinese ROM running on my phone:
(GLOBAL: miui_MI6Global_V8.2.2.0.NCAMIEC_7f3f8ad7c8_7.1)
(Chinese: miui_MI6_V8.2.27.0.NCACNEC_e725f9829f_7.1)
Is there any way to install the global ROM without unlocking the phone? Fastboot ROM also requires unlocking the phone. I seriously don't want to unlock it...
Experts please advice what should I do?
Try using the EDL mode via the EDL cable. It should work on Mi series

Convert Chinese to International Version - Oppo R17 pro PBDM00 to CPH1879 - Need Help

Hi All,
I'm sorry to bother you all, but I really need you help. I live in Morocco and I bought a new Oppo R17 Pro from Aliexpress, I thought it was a global version, but I once I got my hands on it, I realised that the model is PBDM00 which is a Chineese model according to google and the tons of bloatware installed on the phone . I want to install the global firmware CPH1879 with international rom.
I attached 2 images showing all the details you might need to give a hand.
Could you please inform me on how to do that? I really need your help guys. Thank you so much
You're probably better off on the Chinese version. The latest Android 10 update for R17 Pro just came out a few days ago. It is only available for PBDM00 and PBDT00 variants (both Chinese). I'm on CPH1877 and don't have the Android 10 update yet.
@sghir ziane
The mentioned tons of bloatware installed aren't part of device's ROM: they are either installed as user apps or system apps / system-privileged apps and can all get deinstalled / frozen by you.

Oppo Reno 3 Pro 5G Bootloader Unlock help

Hi Everyone,
I've recently bought a Oppo Reno 3 Pro 5G dual SIM from China and I would like to unlock the bootloader to flash an oversea version firmware (with GMS framework). I have enabled the Developer option and OEM Unlocking function and I am having difficulty to get into Fastboot mode. With the phone powered off, I press the volume down button + power button and it only boots into recovery mode. Can someone please point me to the right direction? I also need some help of finding the right firmware for this model and flashing tool. I found this firmware Oppo_Reno 3_Pro_5G_PCRM00_11_A.02_191215.ofp online and not sure if that would be the right one.
Thanks,
Joe

to enter fastboot mode you have to push volume button up and power, not volume down on this phone or you enter in adb shell on your PC the command "adb reboot fastboot"
BUT: I think, there are a lot of hints still not known by us users to unlock this oppo phone. We might like on Xiaomi phones need an oppo Account to unlock.
I myself didn't try to unlock yet. Does only make sense when a working TWRP is out
There was a note in the OPPO RENO forum about getting and running a file from OPPO, after 60 days.
For me the Chinese version is not good anymore, now I can't install any new app on this phone because it says that I have to log in to a heytap account. But if I want to log in, I have to give my Chinese phone number.. I don't have Chinese phone number of course. Any solutions to this problem?
Now the find x2 neo (cph2009eu) released as the global version, and I want to install it's software because it's 100% the same hardware if I know it well. But I can't. I have the firmware for it from the internet, but in a .ofp file, I can't flash it
Okay, now I found a method to install apps without signing in with a chinese number, so the global software is not urgent anymore, but it would be good anyway.
I tried to install the global software via qfil, but it gives sahara error. After a quick search I found that we have to unlock the phone's bootloader to flash the global rom.
But the chinese version that I have does not have fastboot mode, so maybe we have to wait until Oppo will unlock the phone's bootloader officially (probably we have to wait until the next Android/ColorOS beta)
I have bought this EU Version, but funny thing here: they disabled 5G. Mine has 765G, 12GB RAM, dual SIM but neither specified nor selectable 5G
Hi all,
I also own the Chinese version of this phone (PCRM00)
Looking to unlock the bootloader, install EU version of the ROM and also root..
Any help?
Thanks!
Hi,
the Oppo registration ist now available with a none-chinese mobile number. Seems they splittet the HeyTap and Oppo services so you can use an least the Oppo services.
Here is the software update of the global version
https://oppo-uk.custhelp.com/app/software_update_detail/p_name/Find+X2+Neo
It gives an error, so suddenly we cant install it simply from the original recovery
My variant is just the 128/8gb version, and maybe this also could be a problem, becouse the global phone has only 256/12 variant. So maybe with a 256/12 varint its woth a try

I have 12/256 EU Version (seems to sell in Poland), dual-SIM, 4G only (although SD765G).
Current Firmware reads CHP2009_11_A.08, March security update.
Is this a valid update or will it possibly bring 5G?

If you have the single-camerahole, 765G version, and the phone is CHP2009, this update maybe woth a try. The problem could be that Oppo dont allow to change the firmware in the official recovery, only update is possible, so if I try to install the global (CHP2009EU) on my PCRM00 (chinese) variant, it fails and dont install anything. And we dont have custom recoverys yet, and the chinese version dont even have fastboot mode to unlock the bootloader, so it seems impossible for me to install the global until Oppo dont unlock our phones bootloaders officially (for example for a beta upadate)
But if you already have CHP2009 software, maybe the update that I linked worth a try. If the recovery allows it..
If I know it well, the CHP2009EU (Oppo find X2 neo) have 5g modem, just like the chinese variant that I have (Theyre the same phone, but the software is different. I want the global software instead of the chinese becouse of Netflix HDR and Google assistant)
It is the single camera hole but 5G disabled- See Spec
I'd show you, but I cannot share screenshots here.
Would it reject update if it was not functional version or would I brick the device, if I flashed incorrect version?
The difference I see ist that X2 neo has single SIM and Reno3 pro has dual. I know from other brands, that this can brick the phone.

There's always a theoretical chance to brick your device when you modify the software, it's your responsibility. But I think there's more chance that the original recovery that we have won't allow you to update your software to the X2 neo's software. If you want 5g, you can try the Chinese variant's software, but I think the recovery won't allow the other softwares to install

I have it now for three weeks, no need for 5G, so better have a working than bricked phone currently.
Probably I'd play around in one year, when tools are more stable.
In fact I considered to search for an update on Polish Oppo site and found an update file for my Reno3 Pro, that was exactly the same as from your link and X2 neo.
So I did the update via Recovery, it ran through and landed with version .28.
It did not change anything on supported bands.
I remember from Sony phones, that bands are defined in NVRAM.
It seems that for all Reno3/X2 variants with 765G the firmware is the same, it is distinguished only by supported bands.

Can you send the link from this update? So we can install this on PCRM00 via recovery?

I just updated from Polish site to latest version:
https://oppo-pl.custhelp.com/app/software_update_detail/p_name/Reno3+Pro
Now I am on June 5th security level.
The former file from UK site is exactly the same:

Just tried the polish version on the chinese variant of the phone and it gave me an error.

I also tried it, dont work :/
I don't know if it's really helpful but i think I've read somewhere on the official website that 5g isn't unlocked yet and would be thru future updates.
I live in the Netherlands and my Reno pro 5g should arrive today.
I'm kind of lost by all the different variants though..
The find x neo is also for sale over here and it seems the same service expert a minor different front cam.
But here in the Netherlands they are both for sale but the neo is much more expensive.
Anyway, I'm excited as this will be my first Oppo.

Hello, maybe you could help me with my situation, I have an RMX2086 with RUI 1.0 Android 10 build A.53 and I want to unlock the bootloader, but the deep test application comes out approved, but when the test started it restarts for 2 seconds on a black screen and letters in Chinese and it restarts in normal mode, I wanted to know if maybe you could share how to upload the software version to a higher than A.53 to try to unlock the bootloader
Same problem here downgraded to find out that all google services doesn't work damn :/ any help out there i see no comments !! pls
Hi everybody, i'm facing the same problem.
If anybody has found the solution to fix this issue some help will be greatly apreciated.
The only solution in my case is to install a new firmware via recovery mode but unfortunately there is no ozip file available, the only available AND I STRONGLY RECOMEND TO NOT INSTALL it .
The indian one is supposed to rollback from android 12 ui3.0 to android 11 ui2.0 but you'll get stuck in a dead end !! No more google protect no more updates apps or system....
No fastboot mode available, it appears just a second and the system is boot right after.
Ii've read elsewhere that Realme has disabled it!!!! incredible why ??
thanks

Question About switching to the Chinese variant

Hi I'm sorry for interrupting but I really need help in here:
So I have a Redmi 10 2022 Global and I tried looking for the Chinese ROM and I find it but for the Redmi 10 which makes wonder is it the same? If so and if I proceeded with the flashing process will I still get updates after switching?
This the rom I found https://mifirm.net/model/selene.ttt#
Hello,
I would understand the opposite, but what is the real need for switching to Chinese version ?
I would stick to the original version, but here is a trusted website

My problem isn't with the Rom it's about the ability to receive updates after switching to the Chinese variant so I'm just wondering is it possible to get updates after switching to the Chinese variant ?
If you did switch from the Chinese to the global version, were you able to download updates via updater without any issues?
