Bought phone Mate 9 second hand.
How can I be sure what version is it or if its been rebranded?
About phone says its a MHA-L09 and build is L09C432B182
I tried to upgrade it to newest b193 with method in this post [Guide] Mate 9 Flash Update Package and Rebrand
but after upgrade i noticed I lost MEID just zeros, same with PESN when type: *#06#
I am not sure if those numbers were the same before upgrade or something just went wrong.
Other thing is that phone doesnt recognize sim cards after upgrade, it works fine with b182, even if I do upgrade with normal software upgrade throuh phone it finds b190 and again sim is not recognized.
It made me thinking ,how can I actually know what version of Mate 9 i have? I went to huawei web site to check warranty (http://consumer.huawei.com/in/support/warranty-query/index.htm) for this phone and acording to its serial nr/ imei and it says its a MHA-L09B ?im slightly surprised as i found out L09B is an Australian model? live in UK . my serial nr is UGM0217122003582 can someone advice? also if its L09 so i suppose it should have only 1 sim , then why if i go to mobile network there is an sim 2 network field (grey out) ,is that how it should be?
thx
You have 2 sims cause u rebranded ur phone from single sim l09 to dual sim l29.
Better to rebrand it back to l09 so you can hve ur iemi back and working network.
Read carefully , I have IMEI with all brands , I lost MEID and PESN not IMEI, also never rebranded to any l29 always used l09 that's the point

Are u sure it was L09 Firmware u used? Because if it shows that u have 2 sim now u used L29 Firmware when u flashed it, if u flash a L09 that is the singel sim version with a L29 Firmware it will show that u have 2 sim slots in the Settings.

1. bought phone mate 9
2 have no knowledge of its history and if it was rebranded or not.
3. phone info clearly shows MHA - L09 C432B182, IMEI was also there and mach serial number according to huewai warranty checker
4. tried to upgrade many times to newest MHA-09 C432193 but always had some issue with it finaly somehow i did it, phone info was showing MHA - L09 C432B193 IMEI was there but i noticed there is no MEID just zeros
5. confirmed that with dialler: *#06# MEID and PESN have just zeros IMEI is there
6. inserted sim and phone had to noticed its there as had pop up from sim vodafone if i want to use prepay or postpay, after selecting either of two : no service.
7 in settings , mobile network there are 2 sections sim 1 and sim 2 both ,grey out
8 rebranded phone with MHA - L09 C432B186, all went ok but results the same, phone upgraded mobile network still shows sim 1 sim 2 both greyout, no service
9 again flashed phone with MHA - L09 C432B182, straight away phone picked up signal. mobile network still shows sim 1 filled with info and sim 2 greyout.
10.having installed MHA - L09 C432B182 i upgraded software through official way settings ,system upgrade : system found MHA-L09C432B190 proceed with that , as a result system upgraded but again sim 1 sim 2 grey out no service.
Thats why im wondering if there is any way to find out phone original region/brand/version ? how can i know if i got L09 or L29 regardless software it has installed?
Something there is definitely not right if the official phone upgrade screws things up ,there is no service and only firmware that works is 182.

Seems it was single sim branded phone and the previous owner has flash it to single sim unbranded.
I think l29c636 firmware can fix it. Just flash an approved firmware.
I was curious as a colleuge of mine recently purchased the OP8 5G from T-Mobile rather than directly from OnePlus. The sim tray only supports one SIM, and I am assuming that as it has been done historically on prior OP devices, the T-Mobile OP software only supports one sim card. I am unsure as to whether the T-Mobile variant has hardware to support two sims or not, but I think it may only a software issue. Would rooting and flashing to get onto the Global firmware enable dual-sim support for a OP8 5G T-Mobile variant?
Thank you,
I'd assume so. I'm planning on trying this myself when my dual sim slot comes in from Shenzhen.

What is the dual sim's use case for you? International travel or work/personal use?
I think in Asian countries, people often get 1 cheap SIM for cheap voice plan and another SIM for cheap data plan.

In my colleague's case, for work and personal use. I personally have my OP7 Pro as my work phone, and it is the unlocked non-carrier variant, so the dual sim support is there. However, for my use, too, I would like to have the capability available on my T-Mobile OP8 5G just as my colleague. I had him order a dual-sim tray from eBay, and from a US seller to get the item faster. If it works for him, I'll likely order the dual sim tray.
i dont think the global or eu roms support dual sim. there was a disclaimer under the network & sim settings untill ob1. not sure if ob1 supports dual sim yet
Dual sim works, however, i cant get my Verizon sim to work with t-mobile. I get the CDMA-less notification, i read that you can get it to work, you just got to call verizon to register your imei with them so dual sim can work. This is running open beta, stable 10.5.12 wouldnt see my second sim.
I havent called them because my verizon sim is through work.

And, this is on a T-Mobile OP8 5G? If so, I wonder if my colleague would have any issues running two T-Mobile SIMs on a global ROM? (I suspect the T-Mobile software doesn't even recognize a second SIM).

Yes, this is on my t-mobile OP8. I converted to global because I prefer global. I haven't tried two t mobile sim cards, and I haven't tried using t mobiles firmware.

So, after receiving the dual sim tray, and inserting two SIM's on T-Mobile's software--it does not even recognize the second SIM. What particular guide did you use to port over to the global firmware? Thanks!
I would also be really interested in knowing how to get the second SIM to read on the T-Mobile IN2017 variant of this phone. I've been tearing my hair out trying to get this to work, now that I've seen that the international models running Android 11 OB2 seem to have functional dual SIM. Personally, I kind of gave up on getting Android 10 to do dual SIM- even with the European ROM (which I'm fairly certain is the only way dual SIM on this device was ever officially supported by OnePlus), I haven't gotten it, but I think I'm annoyingly close. T-Mobile MSM to Global 10.5.12 to Android 11 DP2 will get you non-functional dual SIM- the device will see both SIM cards, and will properly identify them and their phone numbers, but the second SIM won't connect to voice or data, no matter what I do. If I upgrade the device from DP2 to OB2, the dual SIM UI stays (if I go directly from Global to OB2, it doesn't show), but the second SIM slot is still non-functional- no service for voice or data on the second SIM.
For anyone who has gotten a T-Mobile OP8 to properly read two SIM cards, I'd really like to know how- through my hours of messing around with this thing, it always seems like one step forward and two steps back. Hopefully the final release of Android 11 clears this up.
(My two SIMs are from T-Mobile and AT&T, respectively. Unfortunately, I don't think two T-Mobile SIMs has a chance of ever working with this setup on any firmware- "SIM 1" and "SIM 2" share an IMEI. While that's probably okay for SIMs from different carriers, that's not going to fly on the same carrier- it will look like a cloned IMEI to the network, and probably get shut down fairly quickly.)
Has anyone managed to make it work the Oneplus 8 (pro) unlocked USA version with 2 sims at the same time ? Thank you
It's working on mine with second simbtray however there is no service with both inserted. BecUzebitvhas the same IMEI as slot 1

1. First of all unlock bootloader and u also have permanent sim unlock from t-mobile.
2.After unlocking your phone will restart, setup your oneplus 8 and enable developer mode and in developer mode enable "usb debugging" .
Note: You must have working adb/fastboot drivers.
3. now restart your phone to bootloader.
4. Download any android 10 fastboot Rom from xda developer.
"I have tested this : https://sourceforge.net/projects/fastbootroms/files/OnePlus 8/10.5.9-EUROPE-OnePlus8Oxygen_15.E.18_OTA_018_all_2007160043_913306-FASTBOOT.zip/download
4.1. For flashing this rom your phone has to be in fastboot mode.
5. After downloading extract the rom and open extracted folder and double click "flah_all.bat
5.1.connect your phone to computer in fastboot mode and enter "Y"
wait for 5 to 7 minutes, in this process your oneplus will restart to recovery mode but never unplug the cable or use your phone during installation.
Note: i have tested dual sim with dual sim tray.

do i need to root to begin with ?
how can fix when me flashing other rom，my sim card don't work, I'm tride unlock bootload , flash fastboot ROM(global),and found Europe style maybe can fix my question,to flash Europe OOS,my sim card always don't work,and my flash hydrogen os (china mobile sim card), it always didn't work,my phone is Verizon model IN 2019, I THINK it's fastboot ROM modem.img file have bugs or don't include my sim, I change it, always don't work, please help me
The sim card can be recognized but cannot be used
What SIM do you have? Do you use T - Mobile, etc. or do you use Verizon?
I can always give you your modem. img if you require it.

China Mobile Sim card，phone is Verizon
I don't believe it was a good choice to buy a Verizon model OnePlus 8 in a region where Verizon cannot be used at all. China Mobile SIM cards can likely not be used in the United States and are likely not compatible with U. S. devices at all; hence the reason to buy a different SIM card when travelling to a different region. do you know if your device is unlocked?
Xryphon said:
我认为在根本无法使用 Verizon 的地区购买 Verizon 型号 OnePlus 8 不是一个好选择。中国移动 SIM 卡可能无法在美国使用，并且可能与美国设备完全不兼容；因此，在前往不同地区时购买不同 SIM 卡的原因。您知道您的设备是否已解锁吗？

I'm in China，when i use Verizon oxygen os my sim card have signal，just me flashing other rom my phone signal don't work，The sim card can be recognized but can't connected and use
It's possible that custom ROMs somehow don't support China Mobile; does it say anything when you enter the Mobile Data settings?

Hey everybody today i received 2 op9 both are in le2115 but one was single & another 1 is dual sim
I thought its some kinda bug so i flashed eu/In/gl rom but its still same
Then i flash dual device with same file's so its still dual
Its make me thought about it
I even checked rom and every possible Way where firmware locked the 2nd imei but its still showing single imei
In os11/os12/os13 in all its showing only 1 imei
Anyone have Idea about it?
If anyone able to help or even give me idea about it please DM me
I'll Donate If anyone able to solve this issue (JUST DM ME IF YOU HAVE ANY IDEA ,MUST)
You sure one was not just converted. The dual sim is correct as that's the global model. We're these phones new or used?
Both are new and not converted coz I flashed many time by same rom
