<![CDATA[How to Downgrade Nord N10 T-Mobile?]]>The Ubports installer is telling me to Android downgrade my Nord N10 from 11.something to 10.5.8.
It seems T-mobile has taken away the local upgrade button on the phone.
Do i have to downgrade? if i do, how do i do it?
Ubports does show a link for downgrading that includes MsmDownloadTool V4.0.exe
I dont have Windows handy, only linux or Chrome btw

Thanks for your help!

For some stupid reason on our part, you need to get a token from OnePlus to unlock the bootloader, which you don't have to at the moment in the rest of the world.

First, you need to download the latest oxygen os firmware for your phone. Second, you need an EDL flasher tool like OPLUS EDL Tool or DeepSmartTool Unbrick Tool that supports free flashing.

Download the firmware and unzip it on your pc select the model from the tool. Select the raw programming file from the firmware folder. Turn off your phone and turn it into edl mode by holding volume up + down and insert the USB cable. Then connect into PC and start flashing with OPLUS EDL Tool or DeepSmartTool.

Download Nord N10 firmware - EDL firmware
Download OPLUS EDL Tool - OnePlus OPLUS EDL Tool
DeepSmartTool - Unbrick Tool for Qualcomm

I had meanwhile procured a global version and have been daily driving it for a few weeks. Works great! Thanks sincerely for all your work.

I'll probably still convert the TMobile one.. even if I sell it, good to have more phones out there running UT.

The number of devices I have got hold of that were "network unlocked" or "SIM free" but weren't is countless. I have about 10 pay as you go SIMs on the go to account for this (apart from UK O2 who are £$%$£)****)....

I've just bought an N10 that turned out to be from T-Mobile (didn't expect this, as it's not a carrier where I live), and am debating whether I need to return it.

The readme that @rubencarneiro mentions (and authored - many thanks!) says the T-Mobile firmware 10.5.8 version, BE88CB, is unsupported.
I presume the whole device is an issue, and that it's probably a bad idea to try to downgrade my T-Mobile phone to the Global BE88AA 10.5.7 firmware?

It may still be possible for me to return this phone and hope to find a Global version.

Is your device still carrier locked to T-Mobile? If so, before installing UT, it would be advantageous to get it carrier unlocked if available so you can use any SIM in it.

The device is not avicii, it is billie.

You need to download the firmware from one of the two links on the device webpage and unzip it. There you will find the MSM download tool packed with the firmware.

The tool will open a dialogue box, choose other and next to get to this similar screen (this is for the OP6T but the screen is the same):

Put the device into EDL mode, when you see it say connected on the COM line, press start and leave the device alone. It takes about 5 minutes to install and boot into the Android setup.

Installed the qualcomm drivers (obviously the correct way because device was detected by device-manager under ports as Qualcomm HS-USB QDLoader 9008), installed android platform tools, and downloaded msm download tool (it was in avicii_14_E.04_200716.zip) Then I set the device in edl-mode and connected it, but msm tool does not recognize it, it always shows "waiting for device" and no download is happening.
What did I do wrong in the process, any advice is very appreciated.

The thing is MSMD tool is made for Windows. Even though I would never steer anyone towards Windows for anything(except gaming) this is a rare instance when my advice would be to use Windows.

If you want to ignore my wise advice and you're bold enough to try wine then take it slow, be observant(do not proceed if weird behavior is observed), and cross your fingers lol.

Again I want to stress, flashing chips is dark magic. Using MSM on the wrong setup may be disastrous. It's your choice(use Windows :)).

It can be done on Linux, but Windows is easier (IMHO) :astonished_face: ....

You have to put the device into EDL mode which involves powering off the phone, running the MSM tool as Administrator (Windows) , ensuring your USB cable is plugged into the PC. Then hold the Volume UP and Volume Down button together, plug the USB cable in and release the two volume buttons. The Phone will stay blank, but show up on the MSM Download list in one of the COM ports. If it does, quickly hit start and let the program run.

It's when things don't go to plan, that becomes worrying. I have downgraded a lot of these devices and others now, very little goes wrong, usually the phone is not in EDL mode. Simplest thing to do is start again. Any issues ask here or on one of the Telegram Chats.
