Yes, before you flash the ROM. Main reason, is that the firmware will install stock kernel (therefore over-writing any kernel that is present); so you will want to flash the firmware first, then the custom ROM. That way, the custom ROM install will have the corresponding kernel (if its different from stock, which it may or may not be).
You will also need to re-install custom recovery, as the firmware includes stock recovery (which over-writes the custom one you have now).
Not even remotely similar. You need to flash with hboot. You can follow the excellent instructions here: http://forum.xda-developers.com/att-...nse-6-t2837365
Or here: http://forum.xda-developers.com/show...postcount=9592
In actuality, it is possible to make a recovery flashable zip of the firmware. But I've only seen this on other devices, and haven't seen anyone go to the effort of creating it for the firmware you need.
The firmware version listed on the software information in settings is not an actual representation of your firmware version. Go into your bootloader and see if your firmware version matches your ROM software version.
For example, the bootloader for firmware ver, 2.12.401.3:
Example of rom software version, 1.12.651.17:
I am on ARHD 10.2 and using 2.22.401.4 firmware. I used this tutorial: http://forum.xda-developers.com/show....php?t=2696282
I am having connection issues (says I have 4G but I get no data. switching airplane mode on/off fixes this) with this particular firmware and researched that I have to flash the 2.22.1540.3 for my ATT phone. I haven't downgraded yet since I am trying to get more feedback for this issue.
Incorrect. His screenshot indicates hboot 3.18, so he is on updated firmware.
However, its a known issue that the "international" 2.22.401 firmware does not play well on US networks. He needs to install 2.22.1540, as he already mentioned.
If you flashed 2.22.401 firmware onto the AT&T version, you should try 2.22.1540 as I just described above.
2.22.1540 firmware is linked in Post #2 above.
