I flashed a 4.3 custom ROM and I get baseband unknown, IMEI unknown, and no reception. I used to flash 4.3 ROMs without trouble but after I installed one specific ROM, my phone can't accept another 4.3 ROM.
I tried flashing back stock 4.2.2 ROM and it fixes everything. But when I'm installing 4.3 ROM, I get the same problem.
Please help me. Thanks.

Which was that one specific ROM? Didn't you took the Nandroid before flashing that one specific ROM?
I doubt that one specific ROM might be PA RC2,right??
Try flashing any rom,gapps, bootloader(optional-z20i latest),radio(.84 latest) . :good:

It's not PA, it was Cataclysm. I haven't tried bootloader, will do and report back. Thanks for the suggestion! I did a Nandroid though but I want to try another ROM.

Last week I first flash KK baseband, then flash CloudyStock by Cloudyfa, upgrading from JB to KK.
If I want to downgrade to JB by kdz, should I flash JB baseband first? Or the JB baseband has already included inside the JB kdz?
By the way, could someone plz briefly tell me the difference between the efs and the modem? As I know, the modem represents the baseband, right?

Hello! Are you sure you want to downgrade back to stock with a kdz.? You can always flash a stock 4.2.2 rom if you want that (flash jb baseband first) and keep recovery and root...Or you can just downgrade with kdz, no need to flash JB baseband first, it is included inside the JB KDZ.
The Efs partition is a partition where a lot of important radio data is stored. Without this data, you won’t be able to use your phone correctly. So therefore it is important to have a backup of your efs partition, (because it is unique) in case it gets corrupt.Your modem is a part of the firmware that controls the cell and wifi radios inside the phone, so without a working modem, you would not have data, signal, or wifi connection.
Hope this helps!

First of all, thanks your answer!!
I downgrade to 4.2 by flashing JB baseband first, but there's no D802 TWN modem(I live in Taiwan), can I flash other country's baseband(such Hong Kong, or Europe)?
One more question: whenever I downgrade to JB or upgrade to KK, the efs partition won't be changed, while the modem will vary, right? Sorry for my bad English.
The efs partition will never change if everything is as it should be, and yes you can flash other countries kdz. Keep in mind that you might not get 4g connection because the 4g frequency vary in different countries (like 2600mhz, 1800mhz etc)
Btw do you have a backup of your stock jb rom? You can always flash back to that if you have a backup
And yes the modem will vary from kitkat to jb:good:
Keep in mind that I am not responsible for what you do...but otherwise hope this helps
If I downgrade by means of flashing JB modem then JB rom, not by kdz, my question is: if I flash different countries modem, my 4g may not work, right? Besides this, is there any side-effect?
So the only way to get my original modem is to flash my country's kdz, then use tools to backup my JB modem as well as efs?
I never backup stock JB rom, because it's very easy to flash kdz at the first time, while it has been more complicated last few days.

I don't even have any backup and so the volte is completely gone from my phone. Have installed all versions of firmware, downgraded and upgraded etc etc but still no help. Someone please tell me what to do to get the volte back without rooting.
