To downgrade you need to have recovery older than currently installed on phone. Flash recovery and adb sideload older firmware. If that doesn't help then read further.
Backup your data if possible then full wipe using twrp (not sdcard or ext-sdcard). To flash twrp you need search here how to.Now flash full .178 rom. Hope it helps.

This problem occurred to me several times in two different ways. The first one was on stock rom without root. It was hardware "failure" and I simply removed the SIM1 card put a little pressure on the upper metal that holds the sim from falling and reinserting the sim card. After several tries it fixed this problem.
The second problem was software failure after upgrading roms. This still happens today and many users have similar problem. I am fixing this problem by doing a full backup, then format /system and /data, and installing a clean ROM and at last recovery.
I think the first solution should help you.
cheers!

you have to install emui 3.1 again for your model using fastboot method, you have a dual sim device
have to unlock your boot loader

Well done then, how it works RR custom for you?

I have the same Problems. After flashing with DC Phoenix and reflash the original B170 Firmware my Simcard is detected, but I don't have a Cell Network. What can i do in this case? Boot loader is open and TWRP is installed.

No sir, china models support all networks bands, just flash emui 3.1 via fastboot method

can't activate SIM cards after flash.

Hi everyone.
I have been unable to activate the SIM cards (slot 1&2) on my MZP xt1645-03 after flashing the xt1635-02 rom. I have had a NO OS installed message in TWRP Addison (English) before I successfully install the Nougat Deodex 7.0 stock ROM via TWRP.
Anybody have had similar experiences?
Any fix?

Maybe modem is wrong or missing. Try to flash it manually again or for your region. I saw thread how to convert single sim phone to dual. Check that as well.

Samsung Galaxy S20 Ultra 5G

I have 2 big problems with my Samsung Galaxy S20 Ultra 5G Android 11! Bought it in Spain, have installed Samsung Firmware through Samsung Menu and BOOTLOADER ID is EUX(is from Samsung itself)!!
Bought the phone in Vodafone shop so this is my service provider Software version: SAOMC_SM-G988B_OXM_ATL_RR_0030 ATL/ATL_ATL/EUX/ATL
I bought a Network Unlock code installed a PHE stock rom firmware but didn't change a thing! So I don't know if the Network Unlock code worked or not because it stays registered at ATL=CSC code Vodafone(Spain)
Tried to uninstall pre-installed service provider programs, got some definetely uninstalled but not all of them, reinstalled an other stock firmware PHE again and nothing got changed again!
So now I need help from real wizards to help me with this problem!
I want bootloader ID CHANGED to PHE for example and want all pre-installed programs definetely uninstalled from my device, at the moment they get automaticly installed at the end of installing new firmware!
Doesn't something exist to format but real format as a SDD from a PC? Something like that should be found out that we can wipe everything and start all over again!
Is there not such possibility with unlocking the bootloader and installing new stock firmware again? I tried that but it fails, does someone now there a solution for?
Network Unlock Code to use to Unlock the Network lock code is locked now because it was a bad code they gave me and now it is asking for a MCK. Anyone knows how to get a MCK code?

Question Fold 3 Does not Update... Problem Solved!!!!!!

Greetings,
I bought a refurbed Fold 3 and love it!
However, it is stuck on Android 12 (Last security update is Sept 26, 2022) and will not update.
Here are some details:
It boots up with an ATT logo
I use US Mobile's Verizon plan
Every time I try and update, I get the following message: "Software Update Interrupted."
Some more details:
CSC F926UOYN2DV14
CP F926USQS2DV14
MODEL SM-F926U/DS
I was thinking of using Odin to manually update the phone, but I don't know what firmware to use.
So, I was hoping I could get some guidance:
Any ideas on why it won't update?
If I use Odin, what firmware should I install?
Thanks for your help!!!!

Problem solved!!!!!!!!!!!!!!!!!
I took out my US Mobile sim card and thew in an old T-Mobile sim card and it updated the phone to the current version.
I then rebooted and inserted my US Mobile card and it works!!!!
Weird... but it worked.
