A while back I got in a big fight with this phone (H8314 on Verizon) where I wanted to roll back to a previous version. Eventually I ended up flashing 52.1.A.0.672 and the phone worked fine. Today I decided to apply the latest update (52.1.A.3.49) and I THOUGHT that I remembered how to do it, but apparently I missed a step or something, and I need help figuring out what I've done wrong.
Here's the sequence of events:
1) When I flashed to 52.1.A.3.49, the network signal is gone (SIM is still recognized though, as it gives me the LTE bars, just no actual network signal) and WiFi was really intermittent.
2) Flashed back to 52.1.A.0.672 (which I had been on previously) and the problem persisted, still no network signal and bad WiFi
3) Used EMMA to revert to Sony stock, but all they have available is 51.1.A.11.51 (which is Android 8!) and now the network signal and WiFi works fine.
4) Tried flashing back to both versions of Android 10 and still had the same problem with network and WiFi
My exact procedure for flashing was:
1) Download firmware from Xperifirm through Flashtool
2) Make sure flashmode and fastboot drivers are installed in Flashtool
3) Delete all .TA files from firmware (both in main and boot folder) and unpack partition into partition folder
4) Copy+paste all firmware files into the newflasher folder
5) Connect phone in flashmode (volume up + plug in)
6) Run Newflasher; hit 'n' for no three times at start, and once in roughly the middle of the install
7) Close Newflasher and reboot phone.
What am I missing?? Is it something to do with the bootloader? Mine was unlocked at some point but now I'm really not sure how to tell what its status is. Something appears to be locking the SIM/network though and I know it's not an issue with the firmware itself (since one version of it was installed and working fine earlier today) so it has to be user error somewhere along the line...
Thanks!
