Sim not detected. - OnePlus 7 Pro Questions & Answers

Ok, I have Tmobile with android 10, unlocked sim, and unlocked bootloader. Then I installed Bliss rom and the only and main issue is that most of the time it doesn't detect my sim card. In the times where it did work I had cleared caches, reinstalled twrps, magisk, even dirty flash rom and gapps. It would work and then I would lose sim after a reboot. It did the same thing when i disabled the encryption. Can I get some help with this frustrating issue to make the SIM work after every reboot, to have it working all the time. Could it be tmobile apps or gapps. Thank you.

My sim not detected issue was because I didn't wipe data!
I solved this myself, yay me. No one said to wipe data.
my way
-format data by typing yes
-on slot A install rom, wipe data and cache/dalvik
-reboot and it should goto slot B
-wipe data, install nano gapps, wipe data, magisk, wipe cache/dalvik and data
-reboot into rom.
-you can also flash dm-verity last to turn off the encryption. I did this in an earlier flash session with maybe a different method but it stuck.
Its such a relief to reboot my phone and the sim is still there.

Update/dirty flashing Euphoria OS freezes at the Google boot screen

So every time I have dirty flashed Euphoria OS, it has frozen at the Google boot screen. This has forced me to wipe system, install the rom, install gapps, and reconfigure settings. What am I doing wrong that can't I update normally without having to wipe system?

What works for me is to wipe cache and davlik before I dirty flash the Rom.
Then after flashing the Rom, SuperSu......... etc wipe cache and davlik again before rebooting.
I have never had any problems dirty flashing Euphoria with this method on both Nexus 5 and Nexus 4.
One more thing. I always make sure to have the latest TWRP installed before I attempt any dirty flash.
Latest version as of this post is TWRP 2.8.5.2

I usually do both of those things. I will say that I used ROM Installer to update it, but then dirty flashed with twrp and it still didn't work. Maybe next week I should just straight out flash with TWRP first?
Okay I just did this today and the thing STILL happens. I'd flash the update, wipe dalvik/cache, then reboot system. Then it hangs on Google boot screen for at least 10 minutes. Then I go back to TWRP, wipe system, data, cache, and flash it again and then starts to work, but all my apps are gone. Why can't I just flash the update and have it done with it instead of constantly tinkering around? Am I doing something wrong? is this what a dirty flash is?
I noticed this in your Log

See if this helps.
If you have many apps, try waiting 10 minutes or longer after wiping cache/davlik before rebooting into android. Or you could try a double wipe.
Apparently, it can take quite a while for cache to clear even if TWRP shows complete.

I've tried this several times yesterday, I think I waited 20 minutes and rebooted again to do the same thing. I also don't have that many apps, I only have 4 rows filled in my app drawer
Okay everyone, I found the problem! All I had to do was uninstall the driver/app for CF.lumen before flashing because it tampered with the /system partition making it unable to boot. I then installed it again after the flash was done.

Cannot wipe phone oever twrp

Hello everyone,
I'm trying to wipe the phone to do a clean installation.
So i reboot into twrp, choose wipe and i select dalvik cache, data, cache and system, i swipe to start the wipe and the progress shows that is wiping, but a few seconds after the phone reboots and goes back into the system.
What can i do?
Tried to flash a new rom without wiping data, got stuck in a bootloop and unable to go back into twrp.
Flashed again twrp, wiped everything and its working again.
Repair the data filesystem by going into Repair option. Fixed it for me
Hello, I will be assisting you in fixing this issue. first of all can I get tghe model version, twrp version and bootloader version?

Sim empty

Why my phone cannot detect sim after I flash a new rom?.
Try taking out the sim card when the phone is poweroff and then boot into twrp and go to advanced wipe-wipe system, cache,dalvik, and data. Now flash custom rom without gapps for first boot. Now reboot to recovery and flash gapps. IMPORTANT-dont flash gapps directly with rom! After gapps flash wipe dalvik cache and when the phone boot up. Reinsert the sim card. Should work. If you have any problems, contact me:fingers-crossed:

hello mate
and when i install Rom, do i need to install on both slots or i can have one has backup (its what i have been doing till now)?
and when i factory reset, what will i lose?
Well, it is difficult to say. Usually, every ROM has its thread, its instructions and its community that helps with problems related to installing that ROM.
It could be a few things:
1) I do not see any mention about wiping data. Usually you need to wipe data and wipe system partition in twrp before you install a new ROM. Maybe that is the issue. However, what you need to wipe is ROM specific.
2) Check prerequisites, what ROM version you need to be running before you flash. Sometimes that matters.
3) OnePlus 6 has these A/B slots that I do not fully understand. From what I have read, if you are running on slot A, update installs on slot B, and then you reboot to slot B and cycle continues. BUT DO NOT TRUST ME ON THIS. You should read yourself. Anyway, sometimes people recommend flashing both slots A and B. For some ROMs. For LineageOS, for example, that is not necessary.
oh, factory reset damn i would want to configure everything again
I think first.
You have to WIPE data, all. Factory wipe option.
Then boot into twrp
First, flash OOS, followed by TWRP
Reboot to Recovery using twrp itself.
And then again flash OOS and TWRP.
Reboot to recovery again (using the option in twrp itself)
Finally, then install your rom followed by gapps etc etc
Then it should work....
is there anyway to do this without factory reset?
no

[Solved] Help to flash custom ROMs

Hello everybody,
I bought a Oneplus 7 Pro a few days ago and I'm preparing it for my daily usage. It's my fourth Android smartphone, and the third Oneplus. So far, I managed to flash everyone of them, with no major issues.
And then, the Oneplus 7 Pro suddenly appeared
I used this tutorial to unlock the bootloader and flash the custom recovery.
From my understanding, the custom recovery is flashed in the Recovery Ramdisk and available for both A & B slots.
For now, I have A and B slots with stock OSS, unlocked bootloader, custom recovery and Magisk. All of this is working.
There began my problems. I want to flash a custom ROM without Gapps and I fail to do it. All instructions around ROM threads seems different to me, I don't get the thing about A & B slots, when I flash one rom, it boots as usual on the stock ROM, if I flash both slots, It causes bootloops and if I manage to launch the recovery, my internal storage isn't detected and I can't restore any backup.
I already used MSMDownload to restore the phone completely once.
Can somebody explain to my dumb person how to do it proprely ? Thanks in advance ! :fingers-crossed:
TL;DR : I fail to flash a custom ROM and make it work.
Yes I had same issues when rooted, it means you lost root. You can try tool all in one to flash recovery and magesik via fastboot. If that doesn't restore your access, on twrp you will have to type in format, then mount, then add rom to storage(this method wipes everything beware)

For now, my phone is working nicely. But that's the process of flashing a new ROM that fails. Recovery and Magisk are already and working.

Thanks, I will try.
When you flash the ROM, does TWRP tell you that if you want to continue you need to reboot recovery ? If so, do you ? Do you reboot recovery on the same slot, or do you flash both ?

Nope, it doesnt tell you anything. Just reboot recovery from reboot menu. Don't touch the slot options
Thanks for your advices.
I'm trying right now, here's my steps :
- Wipe Data, Cache, Dalvik Cache (the standard Factory Reset)
- Install ROM : TWRP logs show that he's flashing on inactive slot A, then B. After that logs said " To flash additional zips, please reboot recovery to switch to the updated slot ". I'm going back on the menu
- Install TWRP Installer like previously
- Reboot Recovery : TWRP ask me if I want to install the TWRP App, I dismiss. After reboot of the recovery, it asks if I want to keep System Read Only, I swipe to allow modifications
- Wipe Data : Can't do it because TWRP is unable to mount storage. And after further investigations, I'm now on slot A, not B as before.
- Reboot recovery to slot B
- Wipe Data on slot B
- Reboot system
And It still booting on the stock Oxygen OS Rom, not the custom one installed before. I'm lost
The problem is that you are not performing factory reset.
Wipe data is not enough,you gotta go to wipe-format data-enter yes and swipe.
That is why you are getting bootloops and twrp unable to mount storage problem.
A/B is pretty simple.
You got two slots for many partitions like system vendor boot and all,but a single data partition.
Flash a rom from one slot,it always gets flashed to the other slot no matter what.So next time you reboot to recovery or system it's gonna be on the other slot.So here is the problem..one rom cannot decrypt data which was initially encrypted by another rom..so you gotta perform a data format instead of wipe.Thats it.

Well yes, I didn't understood the difference between Wipe and Format Data.
So let's resume :
Unlock Bootloader
Advanced -> Install Recovery Ramdisk : Install TWRP
Install -> Flash TWRP Installer
Install -> Flash Magisk
Reboot -> System : Reboot on stock OxygenOS Rooted
Then
Wipe -> Factory Reset : Wipe Data, Cache and Dalvik Cache, that means you just have to swipe on TWRP.
Install -> Flash ROM : Use the install function and install the ROM
Install -> Flash TWRP Installer : Don't reboot, go back and install as the previous step
Reboot -> Recovery : Reboot TWRP and it automatically load the other slot
Wipe -> Format Data : Click and type yes
Reboot -> System : Just reboot and it should load the installed ROM
is wiping internal storage compulsory?

How would you do it ? This is an open discussion, I can't find one and only way of doing it

Not wiping.. formatting..that is compulsory if your current data is encrypted
After multiple tries to verify the process :
Wipe -> Factory Reset + : Wipe Data, System, Cache and Dalvik Cache
Install -> Flash ROM : Use the install function and install the ROM
Install -> Flash TWRP Installer : Don't reboot, go back and install as the previous step
Reboot -> Recovery : Reboot TWRP and it automatically load the other slot
Wipe -> Format Data : Click and type yes
Reboot -> System : Just reboot and it should load the installed ROM
Install -> Magisk
Reboot -> System
Install -> Whathever you want
Reboot -> System
It worked !
