Question IMEI broken after switching Color OS to Oxygen OS - OnePlus 9 Pro

Hello there
I just bought my OP9 pro from Aliexpres, Chinese version with official Global ROM but I read for some members than their IMEI broke up when they installed Oxygen OS.
I want to know if this happens 100% of the time, any of you could revert this or found a solution?
If the seller sends me the smarthphone with the IMEI broken could I fix it later?
Sorry for bad english

Also has the same question. Waiting for answer

same here, I am about to do it

AFAIK you can fix it by backing up modemst1.bin and modemst2.bin, so basically your EFS Partition. But i can not remember how to backup them with this phone

Changing ROM region Honor7X > Risk - Reward questions.

Hello,
I come to your forum because I have several questions;
Sorry to bother but I'm a total newbie in phone system that's why I would like to gather information from you.
I'm in EUrope and I bought a Honor 7X phone but problem is the system seems to be from China region.
I've heard this could lead to several problem such as lack of Updating system , but aside from security Update , what other problem could it cause ? Impossibility to download ? To phone ?
(I know about the impossibility to use customer EU service, but that is not what scare me, the thing that bother me is if one day I couldn't go on internet anymore, use googleplay or other service to download)
Aside from that, I have also heard from your forum about a software that could change the ROM , called SRK Tool .
Here again my main question: Is there a risk in doing that ?
Like if you change your ROM from China to EU , is everything will be Oki Doki as if you bought it in EU or does some Update or Feature will still have issue (except China feature of course) ?
Does there is any risk the phone beeing originaly in China region will lock itself or anything since the system is in EU now ?
Long story short: What is the Risk - Reward of changing your ROM with SRK Tool ?
Sorry for the noob questions , and Thank you for taking time to reply to me and help me.

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.

And yes, as i have understand, there is no 6 Gb RAM device for global market, only Chinese!

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.

Question I bought Chinese version of IQOO9 and want to switch to Funtouch OS

HI friends, I have made a mistake buying iqoo9 from Aliexpress without reading the OS description. I read somewhere that vivo is supposed to be offering the option for owners to switch to funtouch is that true will I be able to do that or was that just a rumor?
Thanks in advance
Hi guys,
same situation for me. I have bought the IQOO 9 pro PD2172A and I would try to flash PD2172F ROM but I don't want to brick my phone.
I hope there is someone expert who can help.
Thank you
Same situation for me!
Bad news guys I contacted Vivo. Switching is not possible as the Chinese version is made for Chinese audience and won't let you flash funtouch. At this point all I can hope for is to be at least able to access USB debugging and remove vivos bloatware.

Hi mate, can you post us the link please? I would try to convince them to give us the possibility to switch to Global rom. At the end we have spent a lot of money for this flagship and if they don't want to lose customers in the future, they should make us happy in someway.
So there's no single way for us now to be able to flash something different onto it? Nobody tried?
the main problem is to find the original ROM so in case of problems you can revert back.
Hi there,

Unfortunately you can't. They won't even let you use root account to use adb debugging mode to remove their crap bloatware. Unfortunate that an incredible phone like this with amazing specs is locked. I would be happy if they let me at least use adb
Do you think it's possibile at least to flash the Global version over the China version?

No the Chinese phone are branded with different model code even if we assume you manage to get to bootloader which they already have locked and when I asked them they said no. We don't allow bootloader access for phones made for Chinese markets
Traying to find the correct stock software to the Chinese version of Iqoo 9 Pro I found instead software to F model not A. I didn't know the F model does exist at all. Recently Vivo released this model (9 Pro) to India market but I am not convinced it is V2172F. Possibly this software could be downloaded to ours 9 Proses after bootloader unlocked. Am I right?

I don't know about the Indian version I looked for the model number but don't seem to find it. Either way there is no point of that. I already tried to do extract the boot file and attached it to magisk here is the catch you can't run that without bootloader unlocked
If you looking for chiness file, you may find on PAID website, such as ROMDevelopers ETC
Quick update I managed to remove a lot of vivos bloatware, not all but most of them using adb appcontrol just wanted to leave this here in case someone may find use of this info
Hi Moe990
I am doing the same and building a list of what is safe to remove.
A few weeks ago I removed an APP that disabled my NFC (Google Pay) - I had to factory reset my phone
Have you managed to remove :
- Music and Video players
- Phone / SMS / Contact APP
Thanks
Nah not everything is removable. But I'm glad with what I removed so far
I noticed I cannot google back up my phone. its greyed out ... so annyoing

Question IMEI's are gone after Android update

Hi, I bought my OnePlus 11 from China, it came with OxygenOS into it, and the system identified an update to be performed.
It was working just fine, but after flashing the update the phone no longer identified my sim card and lost the IMEI numbers.
When I dial *#06#, the screen display 'null' to IMEI1 and IMEI2.
In contact to oneplus support, the guy said that I've got the indian version of the firmware, and that's why my IMEI's are lost.
He gave me no solution to my problem, and I really don't know what to do, because in Brazil we have no support.
Please, anyone help me. I'm only using it for 2 days and its completely useless to me without a sim card installed.

I actually never flashed any firmware myself. All I did was installing the new OTA update the phone provided.
Furthermore, now I know that my Phone is a Chinese version and The seller from aliexpress installed a global or indian firmware into it. Is there any form to install a correct firmware and get rid of this problem?
Ola Melvin, have you tried to factory reset your device?
If you have a Chinese OP11 converted to Oxygen11 chances are you shouldn't be able to OTA unless ocdt.img from CPH2449 is being flashed (Please refer to https://forum.xda-developers.com/t/...ues-after-converting-color-to-oxygen.4583321/ for more details).
My understanding is IMEI is stored on devices only and not affected by OTAs, therefore chances are it's still intact and the problem was caused by a corrupted/unsupported radio firmware. Try to flash the Chinese modem from fastbootEnhance see if that solves your problem.

Yes I did. The problem still remains. I'll try to flash the stock firmware back to my phone. The only problem is that I never did that before and I'm clueless so far how to proceed. Any thoughts?

I've paid a technician who did it for me via remote assistance. It actually fixed the IMEI problem, but now I got a region lock issue.
This phone is no joke.

As are its users buying phones from different regions and from sellers that are flashing different software.
There is plenty of information about chinese version of the phone and what to expect and people still are jumping of f the cliff and after that complaining it was not their fault lol

Question Few Questions About Unrooting OP 11 16/512 CN

Hi! I want to chage phone (unfortunately) coz a lot of my apps is not supported anymore on my SGS6((
I choose OnePlus 11 16/256. Since i live in EU i wanted to import CN version from china (tradingshenzen with global rom - OxygenOS if i remember correctly).
Is it possible to unroot this device without triggering region lock issue? (i receive message that they fixed it finally but dunno hot it works, and if unroot the device the problem will come back)
Can some shen some ligt to me? Maybe someone already try it?
Why CN- the price is much cheaper and they got 512 gb version.
buy it. Someone living in Vietnam, who can unlock and unbrick the region's issues with 15$.
I receive the answer from tradingshenzen and they r saying the bootloader is unlocked. Will it be enough to instal some recording app, or ill still need to root the phone?
And how is with this region lock issue? Coz the TradingShenzen r saying that the problem is fixed permanently and wont occur after rooting the phone, but i read that the problem still exist??
