Have you updated your phone with the latest update? Having the same issue. Waiting for TGY update to come out then I will flash that to see if it makes a difference.

Yes, it worked.
But still the FastBoot instead of the bootloader
Is that normal?
And does not accept a less update than ATFD

Is it possible to change my XSG build to VOD without messing with my OEM unlock?

Hello all. My 935f came with firmware XSG for United Arabic Emirates but I am in the UK and would like to flash VOD instead. I tried as soon as I got the phone with odin but got some error (don't remember exactly but f.w. 2 expected 1?). Anyways, 7 days have since passed and I have access to OEM unlock. 2 questions:
1) does the firmware (XSG vs VOD) changes anything at all?
2) if so, how could I flash this without losing OEM unlock.
Thanks a lot!
Flashing firmwares doesn't effect OEM unlock and I'll install Vodafone bloat, go for btu if you're in the uk

Thanks for this. Do you just flash using Odin? It won't let me gives some kind of SW Rev error . Can it be because of the baseband? I am on BRG8 with build number BRH1 trying to flash BRF8...

No wifi, data mobile and bootloader locked

somebody can help me? i have all title problems, i can't flash a firmware because my bootloader is locked and i cant unlock the bootloader cuz i cant pass from start up config, is same as a google count lock, but i know the Gaccount the problem is i dont have internet, wifi or mobile data cuz baseband not found
1st reboot to recovery and do a factory reset to see if that gets your basebands back.
If that doesn't work, try using Bluetooth to sign into your google account so you can enable oem unlocking and unlock your bootloader, that will give you some wiggle room.
If neither of those work, then try flashing the latest firmware for your variant. In most cases with a locked bootloader you can only flash the same firmware version or newer. If you succeed here, check everything and go back to step 1 if needed.
If none of that works, the only thing left to try is a blankflash. https://forum.xda-developers.com/showpost.php?p=77623934&postcount=5
If all of your problems occurred because you tried flashing a pie firmware not intended for your variant, you might be out of luck at the moment. People are getting into real trouble that they can't fix doing this.
Good morning, I have the same problem, no wifi and no mobile data, I tried to install the same rom and a superior and nothing, I'm working the android 9 pie to see if I can recover my device, because not even with bluetooth connected I could unlock the oem option.

If you know where the contact points are, you can attempt a jtag. Other than that, no one has been able to fix the Pie update messing up another variant.
Edit. This is why I gave the disclaimer in the below post... Never flash a zip not intended for your model or major patch version.

Did u try to connect the Ethernet conection? If u get internet connection that should be able unlock ur device bootloader. As far as for me I was able to unlock my bootloader but still not able to find how to enable WiFi and mobile data on my stock version. I'm still running the device on RETIN version.

maybe you will need to wait for firmware pie for your channel
so, you dont have baseband (wifi or mobile) at all?

Sorry I can't open the link .... U can look for USB to Ethernet connector and USB otg adapter to connect phone. It will give u data connection to the phone.

this is only what i need?
If you've upgraded to a pie modem you can't go back to oreo modem. The best you can hope for is that either the correct firmware for your variant will be released, or that another pie variant will have a baseband that you can use.

If the firmware is for you phone you should be able to. With a locked bootloader you can typically install either the current firmware version or newer.

What does "fastboot devices" show when you run that command? Try reinstalling drivers.

I don't know where exactly the problem is. If the device is in the Chinese software, you can unlock the bootloader, but in the global version so far, there is no way to unlock it... Maybe there is an error in the global software
