Breeze to install
-
@moem Thank you. Got hold of another one and it is just so easy to install to.
-
So, what about cell service? 4G, provider etc.?
I had a OnePlusOne that worked good, just couldn't use it because of the cell bands it needed were discontinued. I now have a Pixel 3a but it's 3G and that's a dud!
I am looking to use the phone on a GSM network in the US
-
@mw4jet Works fine for me on 4G. I am not in the US who seem hellbent on removing 3g and 4g bands, forgetting that Government agencies still use those bands and they are tried and tested technology. I remember when 3g arrived, so many issues, took a long time to iron the coverage out.
-
Thanks for the quick reply!! I would think 4G will be around for a while, so I may try and find a 6T.

@mrt10001 said in Breeze to install:
set it file transfer and copy the OB25 file to the root of the device (i.e. not in a folder)
.....could somebody flesh out the details of this sentence please. Perhaps named file in the zip to transfer...and how one finds the root of the device! Help much appreciated!
-
@dunbrokin Attach the device to your PC and make sure the USB mode is set to file transfer. The device should then show up in the File manager ( I used windows 11). On the device icon open it up and you should see the usual Android folders etc. Copy the OB25 zip file to the device so it sits next to the folders and is not in a folder, this is important and is basically the root of the device. Then go to system update, check local update and select the OB25 zip file and follow the instructions.
-
In the xda-developers page, there are two files labelled OB25.
-
@sven There was only one labelled OB25 under the rollback ROMs to bring the OPO 6 back to Android 9. I will post the full title when I get a chance as I am not on my PC.
-
@mrt10001 That description is unambiguous. Thanks.

@sven OB25 Rollback build:

@mrt10001 Thank you so much for taking the time to explain all this. Much appreciated.

@MrT10001 Thanks for the instructions! I was afraid I needed to mess with Msm from Windows or something but I wasn't aware of the flashable zips in that thread. I was running LineageOS 20 with F2FS unencrypted data and needed something to really work to revert all that fun to stock
I rebooted to bootloader, fastboot booted TWRP, formatted data and everything except vendor partition, rebooted back to bootloader and fastbooted TWRP again, adb pushed OnePlus6Oxygen_22_OTA_054_all_1908302047_fulldowngrade_f019784c78234a67.zip to /sdcard, flashed it from TWRP, rebooted to System, and was greeted with the stock boot animation and OxygenOS 9.
My host OS is Ubuntu 23.04 so I got the UBports .deb and installed it with apt, opened it up from the launcher, and chose 20.04/devel. Some stuff downloaded, I followed the UBports prompt to go to Recovery, and eventually Ubuntu Touch booted up!
