sim card not working oreo/noughat

hi i have had the pleasure of using the developer oreo img and enjoyed it,but decided to reflash stock noughat img
until the official oreo comes out.heres where my issue started,after a successful flash and start up,my sim no
longer shows as inserted,i even tried a restore of my noughat back up.the only way my sim will work nowis with the
oreo stock img reflashed..anyone else have this isssue

Are you sure you flashed all the files included in the Nougat fastboot package zip? There must be an image called 'modem' and anoter 'dsp' which should take care of that.
Try reflashing the Nougat image once again.

I will try again

Having the same exact issue
Flashing the MR3 factory image results in no SIM card, same with fkashing MR1 @TheCrazyLex
EDIT: reflashed again the next day and it's now working....ugh annoying

Had exactly the same issue. Although on initial boot back to Nougat, everything worked fine.
It was only after a restart or two the SIM was then undetected.
I'm flashing stock Nougat again just now, hopefully that resolves it for me too.
EDIT. Ok I've now tried flashing multiple images, they all flash successfully and boot successfully, but none of them are detecting a SIM card.... any ideas anyone?
EDITS AGAIN: It would appear now working after flashing Oreo again, then back to Nougat. Very odd....
I want to lock the bootloader again, which is how I ended up in this mess, so I'm now flashing latest Global ROM again, rebooting and then attempting to lock the bootloader again.
I shall update with results.

any update in the same boat

I'm still having same issues,I'm just using Oreo which is working really well.only downfall I noticed is tethering doesn't seem to be working on it

Are you running the right image as Razer and Three have their own build so wanted to point this out as ThreeUK may not work right with the Razer build. i Remeber them saying something about making sure you use the right build

UPDATE - if anyone is having this issue.
--Take the Oreo preview and flash_all.bat via bootloader
--Let it boot and get in to Android just so you can enable debugging via dev options
--reboot to bootloader and flash_all.bat with the latest Three or Global image
--Again let it boot and enable debugging again
--Now reboot to bootloader, and do BOTH the following in fastboot:
---- fastboot flashing lock_critical
---- let it reboot and go back to bootloader again and perform the next lock
---- fastboot flashing lock
Once finally back in, only then did I have a locked bootloader + working SIM card.
Hope this helps someone.

Locking the bootloader doesn't fix things lol. I was on Oreo yesterday and flashed back to nougat and had signal and relocked the bootloader then 10 minutes later .y phone rebooted and lost sim. Only was to get it back was flashing Oreo then booting then flashing nougat mr1 and got my sim back. Then I locked bootloader and took the ota and now I'm back to normal and can take otas again

This is such a weird issue. like for instance I went back to MR1 from Oreo and had signal but when I picked the bootloader and ota to MR3 it was gone.then just unlocked bootloader flashed MR3 still nothing. So went back to Oreo and it worked and then flashed MR1 again and randomly worked even after the ota to MR3
So absolutely random.

hi i found a simple way to solve this issue.all i did is use the global 7.1.1 nougat factory img.but before flashing via the flash all bat.swap out the modem img from the nougat folder with the one from the oreo developer one.worked first time and after several reboots.hope this helps....
just an update i just installed recovery,magisk without issues too

SIM card issue
Hey @parky169, @Roxas598, @linuxct, @kickassdave, @joemossjr
Thanks for posting about this issue that you saw about the SIM not being detected. Our engineers would like to learn more about this and EXACTLY what happened. Can you please PM me with the details:
What carrier you guys are on?
What was the previous build you were on before you flashed the Oreo developer build?
Can you please walk me through EXACTLY what happened that caused the SIM to go undetected
Were any APNs changed prior/after?
Were any changes made to the files or phone (rooted, custom ROM, etc.) prior to flashing the O build?
How did you resolve this situation? Is this repeatable?
Thanks again for testing the developer build! Please PM me if you run into any more issues!
Best,
Khanger

Same issue as the rest. I wonder if this will work with the Oreo OTA modem img, I'm gonna give it a shot. I will report back
EDIT: Well there is probably no reason it shouldn't have worked I would assume the modem images are identical in 8.1 Dev and 8.1 OTA, but it does work by putting the 8.1 MR0 OTA modem img in the 7.1 MR3 and flashing. Honestly i ws too lazy and didn't want to wait for the Dev image to download and I already had a copy of the 8.1 OTA ON MY pc.

Hi
I had the same issue, I updated the APN settings from the carrier's website (three) and everything went back to normal!

I can't edit or add any APN setup - nothing happens after saving new or edited APN items.
How did you do that?

Any update on this? I am in the same boat after standard OTA update. Can not save apns either. (at&t)

Thanks!!!

Thanks for finding a fix. I was worried my phone was jacked up. I was having the same issue. I wanted to downgrade from Oreo since there is an issue with HDMI not having audio. I got signal now whoooo

WiFi and Bluetooth don't work after following the unbrick guide

Got my OP3 hard-bricked recently. I followed Naman Bhalla's unbrick guide and flashed down to OOS 3.x. Everything works fine except the WiFi, Bluetooth, and GPS.
The GPS toggle activates when I click on the icon, but it never calibrates my actual position.
The WiFi toggle doesn't activate, no matter how much I try.
The same goes for the Bluetooth option as well.
You can see the problem for yourself here
If I try to flash a new version of OOS, the phone freezes mid-boot and keeps restarting.
Any suggestions?

What happens when you try to activate these from Settings?
Flashing OOS later versions may solve the issues. What method did you use for flashing the later versions, adb or TWRP? Try adb.
I didn't face any such issues when I used the Unbrick Guide.

@rahulkulhalli
Do you have op3 or op3t ? This is for op3 .
If you have op3t use this guide

I tried, but I run into the same bootloop.
I used TWRP touch.
Could you tell me what steps you took after flashing to OOS 3.x?

I simply flashed the then latest version of TWRP and then clean flashed the later version of OOS and then clean flashed custom ROM coupled with flashing of proper firmware after a couple of days, all using TWRP.
Which version of TWRP do you use? After the OOS 3.x boots up, flash TWRP 3.2.3 official and then try using that for the further ROM installations. If this also fails, use adb to install the ROM. Don't go straight to a custom ROM since you seem to have firmware issues.
You haven't said what happens if you try to enable wifi, BT etc from Settings instead of from Quick Setting tiles.

What I think is you need flash the latest wifi and bluetooth drivers. Just download them from this link and flash using twrp
http://forum.xda-developers.com/oneplus-3/how-to/radio-modem-collection-flashable-zips-t3468628/amp/
You may need to reflash the OS after installing the firmware. Don't directly try to install custom roms after flashing the firmware. First flash latest stable build from official oneplus site, boot into OS and then you can do whatever you want with your device.

T-Mobile IMEI/baseband gone...help!

My mom has had a z2 force for almost 2 years...no issues, now all of a sudden data and wifi are gone and the phone doesn't have an IMEI. Seemingly after an ota update. As it's already old o figured I'd try to flash a rom to fix. I've tried returning to stock with the most recent flash all, the last flash all, tried installing lineage, tried installing 10 potato...nothing is working! Anything else I can try to get this working again???
I also tried to run other flashalls from xda, but didn't see a .bat file in the zip file....only a flash file...is there something else I'm missing? Sorry I'm not really proficient in motos

Mom wasn't dabbling in the dark arts known as pie was she? If not then you should be able to flash the latest TMO firmware then do a factory reset from recovery to restore the baseband.

She was still on Oreo when everything happened .....I attempted to flash the latest firmware, but still no luck...that's when I tried to install a pie rom---no luck there either

The trick to restoring baseband is the factory reset from recovery, not a reset from settings or anything else. As for trying to flash a pie rom, hopefully it was just a rom and not a pie firmware. If anything took from a pie firmware you might be sol.

It was just a rom, no pie firmware at all. I tried restarting from recovery and everything to no avail...is there a specific flashall you would recommend? I tried both the March and August T-Mobile ones...don't know if anyone has had success with a different one?

Oneplus 5t issues with hard reset

Hey there,
in all my years using/modding android phones I was never this lost on finding the issue.
My Oneplus 5t was unlocked, had latest blue_spark TWRP 3.40 recovery and stock oos 10.0.0 with the blue spark kernel and magisk installed. I just upgraded to the 8t and wanted to revert my phone back to stock. So I made a nandroid backup in TWRP and used the unbrick tool to get the phone in the fastest way possible fully wiped back to stock.
(https://forum.xda-developers.com/oneplus-5t/how-to/oneplus-5t-unbricking-tool-confirmation-t3733012 OOS 5.1.7).
Well after my phone was fully stock I was already kinda suspicious about it not finding any OTA updates and manually installed the latest oos 10.0.1 update. First it seemed like everything was working just fine but then I realised that the camera is not starting anymore and gives me the error "Error starting camera" ("Fehler beim Öffnen der Kamera). Since then I have tried everything possible for 2 days but I still am unable to fix the issue.
Everything I tried.
1. deleting camera app data/cache and phone cache in stock recovery
2.factory resetting the phone
3.Using the latest 9.0.11 unbrick tool from this thread https://forum.xda-developers.com/oneplus-5t/how-to/op5t-collection-unbrick-tools-t3898890
-with this my wifi was not working but the camera was working again
- and this also showed me (while using mobile data) that there is a ota update available (oos 10.0.1)
- after updating my wifi was working and the camera was not working
4.Using at least 7 or 8 different unbrick versions (still from this thread here https://forum.xda-developers.com/oneplus-5t/how-to/op5t-collection-unbrick-tools-t3898890)
- here I noticed that as soon as I had a android version below 9 it would not show me available ota updates and would not even let me manually update but camera and wifi was working
5. unlocking the bootloader, flashing twrp 3.40 and restoring my nandroid backup
- camera is not working
So as you guys can see I am really close on losing my mind with this phone and I would appreciate any help you can give me :fingers-crossed:
// looks like I need to send in my phone to Oneplus
//Oneplus "certified" service in poland was unable (my guess is they did not even bother) to find the issue and quoted a 300€ repair bill for changing the mainboard ^^

Question poco f3, wifi only working for 1 min after factory reset and not after.

edit: seems like i have to unlock the bootloader to install a different rom, will update in a week

Sounds like a major issue , after watching the video, 2 things I would try remove sim reboot then try, of still fails the ROM must be corrupt , I would reinstall/flash sounds like you tried a factory reset so thats what I would do

thank you for your response. I did remove the sim and factory reset but no change. Can I reeinstall without having the phone unlocked? or is that only possible with an unlocked phone and the fastboot thing?
edit: found out how to local update rom, going to that and see how it goes.
edit2: installed a new rom but the issue still persist.

you meant to say you just did a update? you will need unlocked bootloader I do believe but not positive if your going from stock to stock

I installed MIUI 13.0.3 with this method https://c.mi.com/oc/miuidownload/detail?guide=1 but the same problem with the WIFI persist. If it was an software issue it should have fixed it right? so I'm thinking that it might be a hardware issue instead.

Did you mess up with any wifi or persist thingy?

I installed everything step by step following this guide for installing via fastboot https://c.mi.com/thread-1857937-1-0.html.
