I loss sim signal - OnePlus 7T Questions & Answers

I need your help, by mistake I changed the bands with pdc and I lost the signal in my op 7t, I already loaded the system with msmtool, I installed several versions of roms and nothing, I'm still intermittent in my network. I was reading that loading the mbn file again but I don't know where to get it to restore it. Can someone help me with this issue.

Did you ever get this? I've read in other threads that there is one on this site, but I haven't been able to find it. My imei got wiped, so I re-input it, but I still can't connect to AT&T. I read that others had this problem and used an AT&T qcn file to repair their phone.

There's an at&t qcn file in this thread, where the IMEI has been removed. I used this mod and can attest the qcn file is good. http://forum.xda-developers.com/showthread.php?t=2068041

[Q] I747M - Telus - Won't connect to network - Weird

Hi everyone,
Weird issue with my telus locked S3. When searching for networks it only shows EXT, and nothing else. Is my phone hooped? I already tried a fresh factory restore to stock. Checked blacklist and its not black listed. My SIM works in my S4 just fine. Hallp?
Does your phone show the correct imei when dialling *#06# on the dialler?
hmm

great question. It does...but with a /11 after it.
That's fine. It's the first 15 digits that represent the IMEI.
Have you tried changing the network settings to wcdma only?

understood. I didn't, but i'm doing so now.
Changed to wcdma only, rebooted. Still insists that EXT is the only network and is unavailable.
Which bootloader and modem are on your phone? Do they match the ROM?

Well i reflashed I747MVLUFOB1, and the weird thing is i had to do a factory reset on the phone for it to give me the default setup (when i flashed it..it seemed like it didn't delete everything). Now at least its showing "bars" of service..but will only find the EXT network (and i do mean cellular network here).
Any other ideas?
Did you change any of the modem settings using the dialler?

On a side note, seems like it won't connect to telus, but it will connect to Fido (and will roam on rogers with my international SIM). IMEI is not on the national blacklist..maybe its not the phone?

I am experiencing the exact same problem as you My problems also started after I installed the I747MVLUFOB1 (BMC/Bell version) on my Bell locked phone. Mine was a little more complicated in that I had also lost my IMEI and I had to restore my IMEI. My IMEI is now restored, phone is not blacklisted but same issue of only having EXT as a network option. If you figure it out, please let me know how you fixed it! Thank you
Hmm very strange. Well i did check the IMEI several times (along with the person that brought it to me) and couldn't figure it out so i had to give it back unfixed. I didn't end up figuring out, but i did hear of another scenario..exactly the same with an S5 they had. Wonder if there's a lot more people with this issue out there?
This tutorial saved my phone! Luckily I had a friend with the same phone.

I suspect your NV data was corrupted during a flash aswell!

LeEco X800 Le 1 pro US SIM and IMEI lost

Hi.
I bricked my LeEco X800 Le 1 pro and when I recovered it doesn't recognizes sim and the IMEI number is 012345678901234.
The radio in Phone info is off and I cant turn it on.
Preferred network type can not be changed.
I tried to use QPST to change IMEI, but it does not connects fully.
Tried rom vresions:
Le1PRO_US_X800-ROW-PB-v60-CUOCO92-5.5.014S.zip
Le1PRO_US_X800-ROW-v48RL-CUOCO92-5.5.011S.zip
I used QFIL to unbrick my phone and then it had 8gb rom so i formatted phone.
Now everything is ok except IMEI and sim problem
Help!

I have the same problem. No imei. Phone does not detect Sim card.
There is already topic about this here http://forum.xda-developers.com/leeco-le1-pro/how-to/imei-lost-imei-letv-1-pro-x800-brik-t3430035
We need a QCN backup from working phone to solve this.
Please Try my QCN file from my working phone.
I used Qfil for backup.
The user "mariocolino" from Forum.le.com has confirmed that this QCN backup has fixed the signal problem.
I hope it will help other X800_us owner with the same problem to repair their phones.
Some helpful tools & files.

This worked for me to enter diagnostic mode.
I flash QCN, imei appeared but there is still no signal and no sound, what can i try.
Use this brush tool. => https://1drv.ms/u/s!AidiAJYxvGs2cPhtLogbcsqjYEo
It will get back all system defaults.
BUT WARNING!
It has a malware that installs apps itself.
After brush tool install custom ROM like cuoco92

if 4G doesnt work, try flashing the Non-HLOS from an x800 US image
Yoy can also see if you can activate the bands on the QCN file with QSPT

Cannot connect to LTE (doesn't matter what rom i'm on)

Hi XDA, I have an unlocked pixel XL on verizon network. I cannot connect to LTE or anything other than 2g networks. I have clean installed, changed APNs and tried everything to properly get the LTE back. Help?

I mean this is gonna sound dumb but have you looked at the mobile networks setting page and have your preferred network on LTE?

Yes
Can you change the network operators on 8.1?
Is your unlocked Pixel XL from the USA? It seems it doesn't support the correct bands for your network
All pixels have the same radios. Dial *#*#4636#*#* click on phone info. Change settings if needed
SIM card is toast. I have had this exact thing happen to me. Just go into a VZW store and request a new one. Sim handshake needed for LTE connection only on VZW.

After you got the new sim and installed it did you go back to factory rom and waited a bit for it to connect to the network?

I'm on the February patch, stock. I'm flashing everything, also, is it normal for your phone number to not be your phone number with a new sim?
My number showing up on about phone is 908-770-6054. This is not my number, could it be human error?

Contact your carrier or go in and tell them that it is not your number and that you are stuck on 2g they should be able to tell you how to fix it or if you go in they can fix it
I did contact my carrier, they cannot figure out what to do. Replaced the sim about 4 times, still no luck. I go into testing (secret code) and I am on 1x network @loeffler23
Sounds like your efs data could be corrupt and there is no way to fix that. Or your LTE radio is toast. Did someone try to carrier unlock your phone?

my phone's unlocked by default and there has to be a way to fix efs, not accessible by recovery? (what is efs)
It holds the imei and other radio proprietary info not sure what partition that data is actually in on this device. I think the efs data is no longer in /efs
Twrp used to have a option for efs backup with the data system backup and restore options

Question LE 2127 no signal

Need help here! I forgot to backup my oneplus 9 pro LE2127 when I tried to root my phone using TWRP,and I installed TWRP in my phone's boot partition which wiped out all data in that partition. I used TWRP side loaded Global ROM to recover my phone but the phone doesn't have any signal with sim card in. Used MSM tool backe to T-Mobile 11.2.5.5 and still same problem, sim card can be read but no signal. Flashed T-Mobile modem but modem b failed, it says no such partition.
Bought this phone from third party. Any suggestion is appreciated.

Yesterday updated my device to the new "stable" 12.0.0.0 . And since then I have not cellular signal.
Tried network reset
Tried fix the APN.
Nothing helps
I can receive SMS, and can use the mobile data. But no calls and no send sms. No signal at all.
