No outgoing/incoming calls on custom ROM - OnePlus 3T Questions & Answers

I was using stock 9.0.3 with unlocked bootloader and data encrypted.
Last night I tried to flash Skydragon ROM without any firmware. It booted to system but calls are not working. I then flashed oreo 5.0.8 fw but in vein. I also flashed "9.0.3 bl fw with 5.0.8 key master", even the Calls are not working. I thought there may be some issues in Skydragon latest ROM, so I flashed Nitrogen ROM but with the same issue. It also booted and I used all types of fw but Calls are again not working.
Now I thought the better way to install the ROM is to format the phone. So, I formatted the phone rebooted back to TWRP(latest one) and then flashed the Skydragon ROM with oreo firmware. Now, I am shocked, even if I am flashing the ROM after formatting but each ROM now flashed is having problems of neither outgoing calls nor incoming.
I finally flashed again 9.0.3 ROM after formatiing so that I may get calls functionality.
The conclusion is that I am unable to flash custom ROM.
Is anybody has the answer, what am I doing wrong. How to flash custom ROM?

Well it seems to be pretty much complicated problem while I think not using any firmware is the problem because there is not any other problem that seems to me is bothering with the calling services moreover did you flashed custom ROM from twrp or not and before doing that have you selected wipe and check... You didn't explained your steps correctly I have flashed both the roms to test and they are working fine on my device and going back to stock and again flashing to another seems to work for me you are missing some important step in flashing I think so...

I have flashed many ROMs. and as per my knowledge I flahsed the ROM after formatting the user data.
Then copied the zip files to device after rebooting to recovery off course.
Then you know: flash ROM followed by Gapps. I have flashed NOS, NLOS, RR, Skydragon. All booted but calls are not working.
Finally I decided to overcome the issue.
I flahsed 5.0.8 ROM and after booting I made a clean flash for the NOS.
Now, ROM succeeded and all is working along with call.

[Q] LTE Connectivity Issues with Sense-based ROMs

I have been playing with AOSP and Sense based ROMs on my HTC One and now hit a snag. I tried to flash Instantcoin 7.0.3 and got caught in a boot loop. I had flashed it using TWRP 2.5.0.0 and since it didn't work, I went back and reflashed 2.6.6.3 and restored my Anrdroid Revolution 40.3 (which had been working flawlessly before the Instatntcoin flash). The restore went off without a hitch but I noticed that I couldn't connect to AT&T LTE and had no network service. Tried Viper ROM, nada. I finally restored the original AT&T stock ROM that I had saved, and no dice. The only ROM I can get to work now is CM 10.2 and AOKP.
So since the issues seem to be with sense based ROMs, is it an issue with the radio? I am running .13 when I checked the bootloader.
Anyone else have this sort of issue? I have tried to research it and have not uncovered any info, so any ideas?

[Q] [ROM][SlimKat][4.4.2][unofficial] network issue

Hi,
at first i try to post in the related thread, but i havn't enough posts to do this.
http://forum.xda-developers.com/galaxy-s3/development-i9305/rom-beta-t2535996
After flashing the latest ROM my phone can't get a network connection. Wifi works. I used CWM 6.0.4.7, SlimKat Build 3.6 and the latest gapps from SlimRom (Build 3). I can't receive baseband, network, phone number or IMEI in the settings. All is unknown. Also when the phone starts, it doesn't ask for my PIN.
Re-install doesn't work. Another SIM doesn't work, too. CM 10.1.3 works fine.
Model: GT-I9305
Provider: Vodafone
Baseband: I9305XXUEMK1
Some ideas?
That is not a rom problem, for sure.. What can I say, you are doing everything right, but I might recommend using Philz recovery, I've never had any problem with it. Reboot recovery, full wipe and then flash
Try to flash with Odin latest stock 4.3 kernel and then try again with wiping everything before.
Hey guys,
thanks for your advices. I wasn't at home, so I couldn't response or even try it.
Today I flashed the new SlimKat 3.8 (still with CWM) and it works Maybe it was a problem with the ROM.
Thanks anyway :good:

For sure it was problem with ROM. Actually with radio ROM, not the Android itself.
Make a backup of your ROM and save radio image from it.
Then you can flash some other ROM you like and flash this working radio image after that.

Wifi not working after flashing any rom

Hi all!
First sorry if this is not the right Forum.
I have flashed many roms In my xt1502
But by now it does not matter the ROM i try, WiFi will not work
I am using clockmod recovery.
Thanks of backup i can still keep using pac-man ROM but none of the other roms based on CM11
Thanks for your help.
I have googled and the answers are not clear
I have tried to change kernels and recovery but issues remain still!
When flashing CM12 based ROM, WiFi works again... So i guess the problem is the build?
Solution
Thanks to myself...
I solved the problem: install TWR 2.6 version, then factory reset. Version 2.8 of TWRP makes sometimes "update binary" error.
You must install a ROM based on any CM11 before 20141104, and then you always do a dirty flash of later version of the choosen rom
I guess there must be something ROM in The versions of cm11 after that date, at least form xt1502 model.

problems when going back to stock rom (lineage 17.1 working fine)

hallo guys, i have issues when i try to go back to a version of the stock rom because they wont boot
not sure what im doing wrong, i hope someone can tell me..
here the full story: when i got the device, i checked the stock rom which was ok.
my plan was to use lineageos, so i unlocked the bootloader,installed TWRP and flashed the global vendor, unofficial 17.1 and gappswhich.
this is working fine and i can always reinstall this lineage the way i mentioned above, but i saw that the finger unlock is not working in that rom as expected.
since i didnt test it in stock rom, i thought lets try this and now comes the issue, i can not find any solution to go back to stock rom which is working.
#1 tried to download rom from https://mi-globe.com/miui-firmware-rom-builder-features/19/ which should be flashed with TWRP (howto there).
when flashing, this is not finishing and looks like its stuck in twrp flashing. ok, since the download for other config was broken yesterday, there might be issues.
#2 downloaded stable rom from https://forum.xda-developers.com/k20-pro/how-to/rom-miui-11-xiaomi-eu-t3984691
flashing works, but device is in boot loop then. im sure i was missing something or doing wrong, so i searched for another option.
#3 found a youtubevide about BACK2STOCK https://www.youtube.com/watch?v=KBsWNrKNZzA
downloaded all the needed packages and did it like it was in the video.
result: all flashed like shown in the video, when system reboot is done MI logo is shown around 60seconds and then rebooting to TWRP
#4 i would go for the solution to flash via MIFLASH, but before i break something i thought i better ask here.
since there are so many issues, i would need your help to point me to the mistakes im doing here.
going back to lineage 17.1 is not a problem, i just did again and this is working.
so if you read this, please find time to explain me if you want to.
thank you
yeah, you are missing a step.
you have to format data partition.
check my guide on how to install roms: https://forum.xda-developers.com/k20-pro/how-to/simple-beginners-guide-to-raphaelin-t4020543
also, may I suggest EU/masik instead of stock, its a lot better
in #3 you can see that in the video data is also formated: https://youtu.be/KBsWNrKNZzA?t=190
of course i did this too....was also not working.
reading your simple beginners guide and downloading MIUI EU ROM (xiaomi.eu_multi_HMK20ProMI9TPro_V11.0.5.0.QFKCNXM_v11-10.zip)
flashed it, was also not working/booting. tried also with flashing vendor (the one from lineage) before, no change.....
what should i do?

Don't flash vendor, theirs no need, eu.miui has everything in the one zip file. Just to clarify have you formatted in twrp? The option where it requires you to type 'yes'? Everything gets wiped from your photos and apps all to the rom itself. Then just flash eu.miui and reboot. Works everytime for me without fail.
no i never formatted in TWRP wipe, only used the factory reset and swiped to wipe.
just did a format and flashed xiaomi.eu_multi_HMK20ProMI9TPro_V11.0.5.0.QFKCNXM _v11-10.zip
ITS BOOTING!!
first please let me thank you very much for this help, i was already quite desperate about nothing working except LINEAGE.
fingerprint in MIUI rom is working great, unbelievable!
can you please explain me why this FORMAT in WIPE is needed and what its used for? i was not aware and i can not find it in any of the howtos..
haha, glad it's working. Knew the problem was that you didn't format.
however since you posted on xda, I just assumed you knew format data is not the same as wiping data.
(literally, the most common beginners mistake for this phone)
it's cause of the encryption keys, when moving from MIUI to AOSP (and vice-versa) a format data partition is required.
I stated this in How To Change My ROM? I wanna Try them all!
section in the first post.
under there, FOR MIUI ROMS (since that is what you were trying to do)
you missed the 7th bullet point. (you can also text me on telegram)
(also, in the same guide, I inform people to flash their vendor first -4th bullet point- then in the 5th bullet point you wipe it.)
(this is cause often miui customs and some people are usually on a vendor that isnt there's. you have to be on your region vendor, then wipe it, then allow the miui custom's vendor to take over, else you will face fingerprint problems)
This is just another point most just don't follow.
Umm, if my guide needed anything to be included, or like... needed to be more easy to read and follow... I can edit that if you like.
(use can text me on telegram as well)
edit: just read the xiaomi.eu one, I'll edit it to make it more informative

You're not installing stock ROMs. You are installing custom ROMs based on stock.
If you want to return to true stock grab a fastboot ROM from here and flash it with the Mi Flash Tool. After fully extracting the ROM delete the flash_all_lock.bat file before flashing. That way you cannot accidentally lock the bootloader.
Then choose the 'clean all' option in the Mi Flash Tool before you hit the flash button.
thank you.
my mistake, i didnt write clear. i just wanted to test a miui rom to see how the fingerprint is working there. im happy now with the custom rom based on stock.
but i also went for this solution you mentioned and noticed that on the https://www.xiaomiflash.com/ site only older xiaomi devices are mentioned as beeing compatible.
looks like this is not the point, so im happy to have this option too.

Question Debloated stock firmware/rom

Does anyone know of a stock miui rom for the Spes that has been debloated of ads and other crap and optimised? Don't mind whether it is a recovery rom or needs to be flashed with fastboot (or miflash).
I'm currently on v13 Android 11 the global version, quite happy to remain on that.
Can someone provide a link to the rom?
Thanks.
Look here: https://xiaomi.eu/community/threads/miui-13-stable-release.64441/
I have tested a lot of roms, and in the end I installed the official one and removed software through adb, today I don't have any bugs or strange problems, besides that I can use the camera in its entirety. I got bored with the custom ones, some games don't run, others are terrible and at the moment there is no fix for this.

Ditto, I always appreciate the custom roms and appreciate the efforts developers go to because there are a lot on here that do nothing but complain about custom roms, however I think I'd prefer a stable daily driver. There is no sign of the kernel source being released which would be a big help for the devs.
I've just finished flashing the stock rom and will go about debloating. There are a number of "safe to remove" lists for miui roms so I will get to work.
Thanks the replies guys.

Hi, may I ask how did you flashed stock ROM? I recently tried to flash 13.0.5 A12 on mine through TWRP, it probably refuses to boot because after the ROM has finished flashing I flashed TWRP next. I also know the fastboot + miflash method but everytime I do it, it gives me anti rollback check error
I downloaded the miui.eu rom which is debloated and allegedly more optimised. I went back A11 the same as I had before I unlocked my bootloader. I flashed the fastboot version and used the bat script inside the zip to flash it.

Ok, that's strange, it shouldn't give an antirollback error when you have the same version of android and miui.
Try again with myflash
But surely when flashing the official rom by twrp you damaged something, if I remember correctly the twrp of spes does not have support for flashing a stock rom, even less if it goes as an update.
Anyway, if you want to make your rom boot, try taking the boot.img out of the fastboot rom and flashing that boot.img to your phone and see if it boots.

My first guess was that it was because at that time I was on an Android 13-based custom ROM (Pixel Experience Plus 13 and CrDroid 9.0), but I was proven wrong after I flashed PE+12 shortly before trying MiFlash. Because it gave me the same error (Anti-rollback check)
Oh, I actually tried the flash-stock-ROM-via-TWRP method after I tried MiFlash method, so I doubt that's the issue. But all I can say is a few days ago I flashed 13.0.5 A12 firmware (latest at the time of writing), so could that be that issue?
I might wanna try what you said, thanks for the suggestion. But for now, I'm on EU and may stay for a few months

Always that I need as a base a stock ROM flashed, I "simply" use the fastboot commands that are inside the ROM, I open my ADB/fastboot CMD/terminal, and drag and drop the flash_all.bat file while in Windows or the flash_all.sh file while on Linux. This method allows to me, to can follow the process while the scripts are running, and search for issues (if there are some)
As per the TWRP flashing the stock ROM, it worked fine too. You just need to flash the ROM, then boot to recovery once, you'll find the stock one, then format data from it, then you are ready, either to go straight to system, or if you prefer have TWRP (or any custom recovery), go to fastboot and follow the method to boot to, and then flash it permanently to the ramdisk.
