Us M3 updated to 5.0 but issues now

[lamstang94]

Hey Guys,

I tried updating my tablet from 4.1 to 5.0 and now i am having some issues. I have no keyboard and my fingerprint sensor doesn't work anymore. So i have no way of doing anything. When I try to bring up the keyboard i get the google voice window.Build number shows BTV-W09C128B350. Trying to understand the steps i need to do to get my tablet back and running normally. Do I need to go back to 4.1? Any help would be greatly appreciated.

Thanks

Erik

How did you do the update? Did you use Firmware Finder and it's DNS update or did you use the dload folder method? I used the Firmware Finder method and everything went smoothly even with an unlocked bootloader, You might try to use that method to reinstall Nougat, but you will need a keyboard to change your DNS settings to the one Firmware Finder needs and for that I suggest you try a USB keyboard connected through an OTG cable.

I will say that once you get Nougat working, the 5Ghz radio goes back to not working and the file that needs to be updated to enable it seems to have changed. So far, I can not find the correct file/setting to change to enable it. For me it is more annoying that I can't get it working than necessary because I am getting between 20 and 40 Mbs with the 2.4Ghz radio and that is plenty fast for what I ask this tablet to do.

i Johje,

I was able to rollback to Android 6.0 and 4.1. Do you have instructions on how you did the Firmware finder update?

Thanks again for your help

I used Firmware Finder to update to the most recent Full Update for the US version. After Selecting the firmware choose "Get an update through DNS" and follow the instructions. This will install the beta Nougat and restore your recovery partitions even if you have an unlocked bootloader. Once the tablet has Nougat installed, root by installing TWRP to the Recovery2 partition which will replace eRecovery and leave your main recovery in place. Use TWRP to Flash Magisk and PHH Superuser to root the tablet because from my experience SuperSU does not work for Nougat on this table. Once rooted you can enable the 5Ghz radio by finding the "cfg_btv_hisi.ini" file in the "cust_spec\vendor\etc" directory and then just change "band_5g_enable=0" option to "band_5g_enable=1" , after rebooting the 5Ghz wireless will be enabled.

Hope this helps

I have also tried to update to 5.0. Everything seemed fine, but there is no keyboard, calc, file manager, etc. The "full..hw.." update seems to go really fast and it says it's done but there is no difference in what is on the tablet. Now I'm stuck at the point where it's A7.0, but I cannot do anything. Try getting google voice type to enter a complex email password

Any help on the second phase of the update is appreciated.

Can you use Firmware Finder in your tablet's current state? If so, try updating using Firmware FInder's DNS method. You will need to be able to update your network DNS settings, though. Have you tried using a corded keyboard connected through an OTG cable or a bluetooth keyboard?
I did not try using the dload method because earlier attempts an updating Marshmallow to a more recent build always failed because of my unlocked bootloader.

Unfortunately I could not fgure out how to do anything with it in that state (no keyboard, no internet, etc.). I tried to find a quality rollback for USA, but was not sure of what was out there that was correct. I ended up installing a EU version so at least it's working again (with old Android). I also realized the next day that my USB cord was bad and that's why I could not ADB or Fastboot anything. I'll try an upgrade again in the near future. Thx.

How did you install the EU old version? do you have link to the ROM?
