get error message of "try downgrading modem"

anyone have a way to do write cert on g890a without downgrading modem?

Read a post of a person that already tried downgrading and he ended up with unknown baseband so trying to stay away from that. Thanks in advance.

Hello
Please share you log hide imei,sn,uuid if you want.

We can not help without details. last 2 or 3 digit of baseband do not tell what rev of phone firmware is..

You can always use search & read about downgrade solution http://forum.gsmhosting.com/vbb/12145749-post2.html

Note that you must first check for stock firmware before go for any downgrade.

hi you have to write a combination file designed for 6.0.1
like this: COMBINATION_ATT_FA50_G890AUCU5API1_ATT5API1_CL6309 376_QB10804835_REV02_user_mid_noship.tar.md5.rar

complete root with FIX ROOT.bat
maybe have to flash recovery combination too
after this you can do your JOB.
