Try to change your O2 ROM with the European ROM using Goldcard method

That would DeBrand the Device (removing the O2 Splash screen etc) however it WILL NOT unlock the device to allow another network's sim card to work in the device.
The ONLY way at the moment to unlock your device is to either obtain the code from O2 which you have tried or pay for one through a unlock site such as the one he's already been shown (http://www.htcimeiunlock.com/htc-hd7-unlock)

^^ ok thanks for all of you guys
i'll try that website
i wish that it work..
best regards for you ...

Rooted, remove Device Unlock App possible?

Hi,
I just bought from Ebay an H872 TMobile LG G6 and found out it's BAD IMEI and can't do SIM UNLOCK or cost too much with Device Unlock APP.
One question, any chance to remove the preinstalled Device Unlock App from phone and revoke the SIM UNLOCK CODE instead?

If it is truly a bad IMEI that will not help. Every carrier will check the IMEI when you try and put it on their network and reject it.

It's doable, just check your phone's IMEI on t-mobile servers here: https://www.t-mobile.com/verifyIMEI.aspx
Also to be sure, check your IMEI also here: http://imeipro.info

I've got a locked H872. I contacted Tmo about unlocking it, and they said that I had to have the original owner contact them to have it unlocked, but they will unlock it. I bought the phone from a guy that bought it from the woman who purchased the phone out right from Tmo. The guy I bought it from used it on straightalk with their Tmo SIM. Anyways, I've been looking for a SIM unlock method that I could do myself, to no avail. In 2014 I SIM unlocked a Sprint XT1056 using the NVITEM software...is there anything like this available for this device

I have a similar requirement, I purchased unlocked t-mobile lg g6 but after 30 days it showed up a message "temporary device unlock has expired" and now it is not accepting my Indian sim network.
If you or anyone else reading this post please let me know if there is such software exists that can help unlock it. :crying:

Firmware version for BL029 BL Unlock

Sorry guys, but I'm still confused about which FW versions can be BL unlocked and which can't.
I'm not familiar with the Huawei versioning in the naming of the firmwares.
Specifically, it's BLA-L29 8.0.0.150 C432 that I am wondering about. If someone feels like explaining the versioning in a sentence or two (or point me in the right direction), that would be really appreciated.
Thanks!

In one of the other messages treads some posted this link.

It was Quoted from this thread finally-unlock-bootloader-mate-10-pro-t3850111
I think the version system is different from how you listed. Some people talk about the 8.0.0.xxx With xxx being some thing 142 or 145 but the guides mostly use C432 and c636 for example. This C number you can see on the about software page in you phone as well as the xxx. It usually appears after the version like, 8.0.0.xxx(Cyyy).
The part I'm struggling with is that I have a two sim phone, BLA-L29 and most people her are loading BLA-L09 (single sim version) of software. i don't know if its compatible. I think they are as I've never seen an issue with any other phone in the past. People use to use the dual sim add on's and you never had to update the software to recognize the new sim tray. So I think I can load BLA-L09 but I'm not sure. Still doing my homework.

Thanks, I think I got it figured out now.
According to posts here in the forum, the unlock is not possible from versions >= 8.0.0.145 (which can be downgraded to ...142).
What wasn't clear to me, was the way the versioning works. But apparently it's simply counting up, so 145 is a later version than 136.

C432B142 is the last firmware where DC worked (for C432, other custs have other build numbers). B145 can be downgraded to B142. B146+ use new bootloader which can't be downgraded. So on B150 you will not be able to get an unlock code. I did however see some site which claimed it could get unlock code for any firmware, even on new devices. I'm not sure how reliable it is though and it cost €30

Just to clarify. BLA-L29 8.0.0.143 (C636Patch1) would be B143 so I can downgrade? This is the first time I'm seeing Bxxx.

I saw the post about the 30€ unlock in the P20 forum. The guy said he got his code very fast and it worked - I do find 30€ to be a bit steep though.

Thank you. That worked for me. They were able to provide me with a working code within 25 minutes of my placing the order. My Bootloader is unlocked now.

BLA-L29 8.0.0.143 (C636Patch1)
Edit: If I had to guess, he has access to the tool they had hooked up to the website previously. I have a dual sim phone so he needed the IMEI of the first sim slot. That is the on on the sim tray and the one listed on top in the software.

I think you can. Go to the website. There is a live chat option. Talk to the person on live chat. They will verify if they can unlock your load before you pay.
Edit: I checked and they said they can do it. Here is our conversation below
Hello, can you do mate 10 pro's running Bla-L29 8.0.0.150(C432patch01)?
Yes
30 euro is price

UNLOCK bootloader app confirmed working (Not free though) for the Mate 10 / Pro

Not sure if people are aware of the app DC Huawei Bootloader Codes, but I've just unlocked my Mate 10 ALP-L29 using this app, there are 2 options, a cheap £3 one, which does not work on Android O firmware and the expensive, around £23, which gets the bootloader unlock code from the phone's IMEI, so had a go at it and not even 2min I got an email with the bootloader code and confirmed working, running Android Pie from the OpenKirin team and so far all seems to be working great, so good to be back to stock Android...
Just thought I would share my experience in case someone was not aware of this great app.

Not 100% sure, but it's based on IMEI, so I would say it should be fine, I know the app asks a few questions, but I assume is just to cover themselves... I know it's a bit expensive, but if you're fed up of EMUI it's a risk worth paying, it's like having a new phone

Did your IMEI / SN change?
Most probably it did, unless you used a rebranding method that I'm not aware of.
In this case this unlock code will not work.

Done on a dual sim version.
I send the first of the 2 imei (as seens in the infos) and got my unlook code in 5 minutes.
Unlocked now and use openkirin OmniROM Pie Alpha 2
Working great so far

I don't think this will work for you then, sorry.

still not supported by devices 8.x and above

that is, if I officially upgrade to emui9.0 something me will be available cheap option?

I've just bought a new Huawei Mate 10 Pro and haven't upgraded it in order to be able to unlock its bootloader. The build number is BLA-L29 8.0.0.120(C432), could I unlock it using the cheapest option (instant read bootloader code from phone) ? There are conflicting information on DC Unlocker's website.
Thank you !
Edit: I managed to get a code with the cheap option as I have an old build number on my device !

If it changed the IMEI number then you probably have a phone with an invalid IMEI number as a result, and one that will not function on the majority of carriers. The IMEI number is the actual identification used when the phone communicates, just like with network MAC addresses, no two devices can be active with the same number at the same time.

MI 9 locked to Vodafone

Hey guys
I was wondering if I am able to unlock the bootloader of this phone and flash Xiaomi EU Rom but I am on locked Vodafone network so I am not sure if I will be able to do this because something might go wrong. If anyone has any knowledge on this subject can you please help me out

In a telegram Mi 9 Group I read that someone was in the same situation and he open the bootloader and flashed via Mi Flash a global rom and lock the bootloader successfully without problem.
Do you have telegram app? Search Xiaomi Mi 9 - Espanol on it, and ask there about what did you want to do.

How do you know you are locked on Vodafone? Mine wasn't network locked

Not every phone under contract is locked, if you have a spare SIM from another network it may be worth checking.
Either way - I suspect you won't have any issues. The part of your phone that ROMs are flashed to is on a separate chip to where the network lock is configured AFAIK.

Edit: you were correct sir I tried a sim from a different carrier and it worked perfectly

A dual sim phone is never locked to a specific carrier. You may get some that are "branded", so they have a bit of carrier specific bloat that can be uninstalled, but they never come locked.
