No LTE on current Custom Roms - OnePlus 3 Questions & Answers

So, I've had the latest official stock rom on my Oneplus 3T but decided to install a custom rom. But now whenever i install a custom rom, i lose the ability to connect to LTE.
Does anybody know why this is????
THanks

you need to restore your phone back to stock using unbrick tool then update it to the latest oxygen os 9.0.5 then try putting a custom rom on

Have you tried flashing the stock rom from your stock back up? I have not been able to flash a stock based rom from cm or aosp. Give that a try

Does installing a TWRP Backup also affect phone Firmware?

Hello guys,
following situation:
Long time I had a 4.4.something Rom installed. Before I flashed a custom Lollipop rom, I followed the advice to just go back to stock and let it update to Lollipop so that the firmware will be updated accordingly and I won't run into problems when flashing a Lollipop Custom Rom. Everything worked fine. Now I had to send my phone to HTC for display repair and just to make sure they won't nag about the custom Rom I reflashed some older stock rom via TWRP backup I found here, I think it was a 4.0 or so. The question is, does this also affect my phones firmware or is it still on the current newest level? So when I get it back, would I need to update to stock Lollipop again before flashing a custom rom or can I go for it straight away?

It won't affect your firmware.
Okay thanks, so Firmware should still be up to date and I can flash a Lollipop Custom Rom. I don't know what they do at HTC repair, if they only reset it or if they also update it, well I'll see.

Newbie needs help to install custom ROM

Fellas,
I just rooted my phone and learned from a youtube video about creating nandroid backup. I am really excited by this custom ROMs. I want to install lollipop on my Galaxy s3. I see that all the builds on the download section are nightlies for 12.1, so I am not sure whether I can go ahead and install one. I am concerned about any potential issues as I use my phone to get work emails. Can I grab the latest nightly and go ahead with flashing? Also, can you list any issues that I need to be aware of?
Have you updated your phone to the latest stock ROM? If not, I suggest you update to the latest stock ROM, then use Odin to install a custom recovery, use the custom recovery to create a nandroid backip, and finally use custom recovery to flash a custom ROM.

Downgrade from Android 10 to 9

Hey guys!
I'm rooted with magisk on this ROM - https://forum.xda-developers.com/oneplus-5t/development/rom-unofficial-aosip-aka-derpfest-t3978357/amp/
What would be the best way to downgrade/roll back to an Android 9 ROM? Safely.
Appreciate the help! Thanks.
I just did this process.
You just need to have your twrp updated and flash the stock rom (or other roms).
You'll lose your recovery, it goes to stock, and magisk.
I think flashing a non-stock android 9 ROM is way better, you won't lose your recovery.
If everything goes bad, you can try the unbricking tool for 5t.

So if I'm understanding correctly, it doesn't matter that I'm on the latest firmware as well? All I have to do is find a android 9 ROM (I'm probably going to do oos Aroma) and flash that in the latest recovery installed. Latest recovery being the one I'm currently on twrp 3.3
Yeah, that's it.
I was using aicp android 10 I just flashed lineageOS android 9, all worked well. I'm also using twrp 3.3 that should be OK.

Which Custom ROM works best on MIUI v12?

Hi,
I don't like idea to downgrade my mobile just to flash custom ROM, I have Realme 6 (G90T Series) and flashed successfully a few custom ROMs but I never downgraded the phone, why RN8P so difficult?
Are there any custom ROM that work best on MIUI v12/ Android v10?
TWRP-3.3.1-1210 recovery and Magisk Manager are installed and both working, device is rooted.
If you have root and twrp, you don't need to downgrade to install a custom ROM.
If you are talking about flashing a cfw custom ROM, then yes, you need to downgrade to Android9, but then you can flash Android 10/11 cfw ROMs.
Having said that, since the new unbrick method was developed, you can now feel more comfortable about simply flashing 'normal' (non-cfw) custom ROMs without going the cfw route.
