Yep LTE+ icon ahow on your system but not ca i test speed 4G max speed stuck around 40-60Mps normally 2CA is 100Mpbs++ and i see on network signal guru it's show LTE Not LTE2CA and i try anoter qcn file it's same
ON REDMI 5 PLUS CAN'T USE THIS METHOD FOR UNLOCK CA (in global version MEG7 and my country is thailand)
but redmi 5 plus support intrabrand CA in my country but not support interbrand like b1+b3 or b3+b8 you can check with network signal guru and show me a result @Ksarin112

Need root ?

dont use this method, not useful, yes, you get the lte+ signal, but yr dl speed doesnt change and your ping, esp in gaming, goes right up

How use?

Anyone knows where is the default location for backup, as I used this method and no changes in speed but the battery drain faster and I don't remember the default location, because in order to use this method I selected my download folder to update phone by the downloaded qcin file.

The model number in qcn file and the phone do not match. I have redmi note 5 indian varient

Can you post any screen?

A numpties guide to rebranding

This is simply a collection of information with some blanks filled in to allow those not as well versed in huawei/ADB as myself to rebrand. After 4 days of agony with Funkyhuawei and very little info i managed to resolve the issue myself. Primarilly, rebranding from pie on their toolkit would not work and i did not feel comfortable rebranding the more involved ways explained on here here.
You will need a membership to FH and credits. Also to have selected the same version eg 8.0.0.159 for the TARGET region. for me, i was c782 but rebranding to c432 so selected clt-l09c432 8.0.0.159
It is written with the intention of using FHRebrandTool2, as this one allows you to remain as CLT-L09 if that is your model, not force a switch to L29 even without dual sim
First, obviously, if you cant/havent unlcked FRP and bootloader, stop reading now. You're process is finished lol
Second, remove all security pins and fingerprints (developer options>require to be unlocked>off)
If you are on pie, use this incredibly simple automated script setup from @Androlark thank you my friend for this as you saved me here https://r.tapatalk.com/shareLink?ur...share_tid=3841687&share_fid=3793&share_type=t this is necessary as rebrandtool does not operate correctly with android 9 but fh instructions and even FH help are unclear on
For the correct software, download your latest android 8 version from Firmware Finder, taking note of the changelog, the flashing requires older update version with THREE folders, the giveaway is the changelog says "this will rollback your device to emui8" (dont rollback using Hisuite, as it itself advises not to if device unlocked. When selecting download in FF you may be presented with a list of many folders, most with the same name, simply click one of each name (update, public and cltxxxxxhw) transfer these to your phone after checking "check availability by imei" and doublechecking you have selected the correct region (C782,c432 etc)
Before flashing, to save panic, READ "AFTER FLASH INSTRUCTIONS" in flashy folder of extracted flashtool downloaded from above.
Follow post and flash.bat instructions and its all automated.
Factory Reset as advised when complete
Wahey you're back on old faithful Oreo and still device unlocked
Now startup device, complete basic setup to access menu, ensure adb AND allow adb during charge mode are on (this helps stop adb turning back off at restart in some cases) ensure to forget any wifi connection you used during setup
Back to fastboot (device off, hold power down,connect cable to computer) once loaded run FHRebrandTool2 again, being careful if you use manual entry to assign new model and region
Once complete and you restart you will keep getting connect usb to continue rebrand dont panic, hold power until shutdown then hold volume down and connect usb to computer again, you will get Erecovery. Select Install latest package and use the FunkyHuawei instruction from here, EG change DNS on router or use a computer as a hotspot to install new region software and wait.........wait.........wait.........funkyhuaweis carrier pidgeons are a bit slow
Rebranded and update back to pie and enjoy the precious security updates

Proof is in the pudding [emoji16] currently waiting on hisuite downloading my first update to 161

AXE-LX2 on EMUI9, possible to unlock bootloader ?

Hello,
I'm talking to the XDA community that I've been following for quite some time in research to find a way to unlock my bootloader.
So I've already browsed pages and pages, and I've already seen the different techniques proposed here, but I have a difference that most users seem to lack.
I have a Huawei P20 Lite AXE-LX2 phone, while the majority of people here seem to have an LX1. It is of Chinese origin, under its name Nova E3. It is currently in version EMUI 9.1.0.353(C636E4R1P5) with a security patch of July 2020.
Coming back to the bootloader, I want to unlock it by the Telegram channel or DC-Unlocker, so I need to dowgrade to an specific EMUI 8 version.
Except that I already have the EMUI 8 stocks for my device, but none for EMUI 9. On androidhost.ru, I only found an EMUI 9 archive for AXE-LX2 (https://androidhost.ru/2CNs) by a guy who runs a site called ministryofsolutions.com . By downloading it, the content is protected by a password. So I sent an email to the guy, who told me that the archive was private and not for the public, so I'll never get the password (he runs a real small business in his country).
So I'm blocked at the first step because I don't have any EMUI 9 stock for my AXE-LX2. androidhost.ru only has stocks for AXE-LX1, so those on LX2 or LX3 are literally blocked.
When I tried other sites to find firmwares, I find myself with an archive full of drivers and softwares to install, not at all in the form of the dload folder to put on an SD card.
I also found this old XDA post: https://forum.xda-developers.com/t/ane-lx2-9-1-0-133-c605.3944407/ , but the same, not as a stock to install from an SD card, so I don't know how to do that at all (I put in screenshot the content of the two archives of the post).

Should I take the risk to install a stock AXE-LX1? Or could someone please give me an EMUI 9 stock corresponding to my model?
Thank you

I specify that I must first downgrade to an older version of EMUI 9 because HiSuite, whether in Chinese or English version, does not offer me the possibility to downgrade with my current version.

Hi, don't try it, it may brick your phone.
Unfortunately, there's no way to download Service ROM free for your build number, only for 17euros on paid websites.

After several hours of research, I managed to find a free stock ROM for AXE-LX2 at this address :
https://androidfilehost.com/?fid=4349826312261804346
The installation was perfect, and I found myself with an old version of EMUI 9.1 of at least two years old I think. Unfortunately, HiSuite, Chinese version or not, didn't offer me to downgrade my version, probably still too recent, or I arrived too late. If someone has another solution to propose me, please let me know in reply.
In case the file is down, I can upload it to another service.
Otherwise to get AXE-LX2 EMUI 8 stocks, there are two of them I know of for free on androidhost.ru.

Can't flash ROm with odin - S20+

Hi everyone,
I'v got a S20+ 5G but the old's owner can't give me his google account so my phone is locked.
I tried to fix it by flashing the ROM but when odin told me success, the phone was still locked by this google account.
I would like to try an other firmware but the bootload has changed and now i can't try again the method with odin.
Check the picture of the new bootloader.
What can i do ?
Thanks for your help !
Mike

can you enter download mode ? The way you enter download mode has changed so you need to power off this phone then press and hold both + and - volume buttons and then while holding these 2 keys connect usb C cable to your phone and hold till you will see blue screen. Oh and make sure that your cable is connected to usb on your PC first, then connect it to phone

Ho my god ! Your method give me access to download mode ! Thank you for that
Furthermore, do you think that the google account will disapear ?

nope, flashing different firmwares will not remove lock that would be too easy

So, is there any way to bypass the google account ?

it depends which firmware have you flashed, each month there is a security update and old methods are patched and it is getting harder and harder i think the fastest and easiest way is to ask previous owner for password or return the phone, once I bought s10 and it was locked same as your's but there was possibility to enter previous owner lock screen passcode to unlock google lock and he gave me this code and it worked, check if you can enter previous owner passcode instead of his email and password

Can I use a Global Rom on a T-Mobile N10?

Hello I have a T-Mobile unlock N10 I would like to know if I can install a N10 global Rom or NA in it. I have noticed that the global version have certain settings that are not greyed out
Thanks in advance

I'm using the european rom linked to in this thread (https://www.xda-developers.com/oneplus-nord-n10-5g-android-11-update/) and it is working fine for me on Google Fi (which is T-mobile nvmo). I'm supposedly getting a 5G connection too.

Yes you can. Process can be found here: https://forum.xda-developers.com/t/...to-tmobile-metro-w-locked-bootloader.4297501/

Just to be clear I have an T-mobile unlock n10 but I am using H2o wireless services. I am interested in getting the wifi calling option as my girl have a n10 from oneplus and that option is there for her to choose.
Edit: I believe my Bootloader is not greyed out (able to unlock) as we contacted T-mobile and was able to unlock phone for other carriers
Thanks

I can't guarantee compatibility for your specific carrier but yes the process that I linked you will allow you to install the global version of the ROM on a T-Mobile device.

Cool ...now I saw a thread on magisk for install would any be better than the other method ?...thanks again

If you check out the post "Found a chink in the armor" you'll find a debloat tweak. That will allow the OEM Unlocking to be clickable. Request your unlock token from oneplus, and unlock and root as normal. I just completed it. I am NETWORK LOCKED, for now there is a work around.
You can see here I am still network locked. The other pics will show you I'm also bootloader unlocked and rooted.
