How to Downgrade Nord N10 T-Mobile?
-
@MrT10001 Following @Timespansoul s advice I borrowed a laptop with windows 10 on it. 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 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.

@MrT10001 Thank you very much for your kind help. I managed to unbrick the phone! Thank you.

@messayisto Great stuff. 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.
-
@MrT10001 To he honest, I found out that it is not a N10 but a AC2003. So I decided to give /e/ os a try for this device. It took me hours and was quite a mess, but in the end I succeeded.
Best regards -
@messayisto Ah, I have /e/OS on my avicii. It works really well - no Google :beaming_face_with_smiling_eyes: :beaming_face_with_smiling_eyes:

@MrT10001 is it necessary to have adb and fastboot installed to use MSM ?
-
@Josele13 Having ADB installed makes it easier to boot into EDL mode in order to flash the correct ROM. If you read back through the telegram chat I helped someone install with diagrams for clarity.

@Bunchy are you still around the forum? Did you have success downgrading?
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.

@wally you can install and it will work.

@wally I have the N10 also...the Tmobile version....and Tmobile is not in NZ....but I have just finished unlocking the bootloader and installing Liineage on it. See these two sites!

I have a second Tmobile N!0 (you can pick them up quite cheaply on Ebay now....and when I get the unlock code from Tmobile

I will try putting UBTouch on it. Alos OnePlus support are really helpful!
-
@Dunbrokin I assume youare SIM unlocking first, before unlocking the bootloader?
-
@MrT10001 Twas already network unlocked when I got it!
-
@Dunbrokin That is a joy to behold when that happens. 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 £$%$£)****)....

@rubencarneiro Thanks for the tip! 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.
