I had a problem with a custom rom on my xt1023 so I restored it and installed the official 4.4.4 rom but since the installation, my phone doesn't detect any mobile signal even with my sim card installed in the phone. I tried to restore it and reinstall the rom multiple times but without any success. If someone could help me, it would be really appreciated!
Thanks
Did you try erasing modemst1 and modemst2 ? Try this:
adb reboot bootloader
fastboot erase modemst1
fastboot erase modemst2
Now, try flashing the modem from your stock 4.4.4 ROM
fastboot flash modem NON-HLOS.bin
Reboot now.

I just tried it but my phone still stays that I have no signal.
I don't know if it changes something but I'm from Canada and the only stock rom that I found is US.
Btw, thx for the help

Hello everyone, after unlock procedure and install global stable 9.5.3.0, i lost sim card detection and no signal.
I have a routine to make sim card detectable and signal on. (I have a rooted rom, and unlocked my phone)
First step :
Connect phone with USB
On pc with adb cmd :
adb shell
su
dd if=/dev/zero of=/dev/block/mmcblk0p13
dd if=/dev/zero of=/dev/block/mmcblk0p14
dd if=/dev/zero of=/dev/block/mmcblk0p16
Reboot the phone
At this point i lost IMEI (IMEI 0) but my SIM card is detected.
Second step :
put phone on fastboot mod
On pc fastboot cmd :
fastboot flash modem NON-HLOS.bin
Start phone
Third step :
On pc adb cmd :
adb shell
su
setprop sys.usb.config diag,adb
With QPST on PC, i restore a qcn file found here androidfilebox.com/app/redmi-5-plus-modem-firmware , MEG7 modem version.
Reboot the phone.
Here, SIM card detected and Signal ON, so all is OK.
BUT Fourth step :
When i reboot the phone , i get back to no sim card detected, and i have to repeat the process. :s
So my question is how could i keep my settings and get full use of my phone even if i reboot...
Sorry for my english, i'm trying my best here
i have the same issue on my Zuk Z2, but i haven't make it;
if you could read chinese, maybe this wil be helpful for you.

Read you message.
In reality I never went through something like this on my note 3. My best guess the qcn file you used is not compatible and efs may be corrupted too.
Many users were facing issues like this so I made a thread to help them. Some users reported a permanent fix while some were never able to get it to work.
Possible fix:
Find a backup of modemst1 modemst2 and fsg from another user if he/she may be willing to share.
Flash the files using fastboot command.
Fastboot flash modemst1 modemst1 and so on.
And then change IMEI and Mac address manually.
Worst case scenario:
You may need a motherboard replacement if nothing works.
But I think it is possible that your efs partition as a whole is corrupted.
adb shell
su
dd if=/dev/zero of=/dev/block/mmcblk0p13
dd if=/dev/zero of=/dev/block/mmcblk0p14
dd if=/dev/zero of=/dev/block/mmcblk0p16
These command erase the modemst1 and modemst2 and fsg partition that makes up the efs. What you need is these three partitions from someone else device that are not corrupt and flash them on your device.

Thanks to answer, i'm gonna try to get those partitions, it could be hard
I'm facing very similar issue after an ota update. However, I get the sim detected on a simple reboot for a few minutes. Please update if the solution worked.
Hello. I'm facing similiar issue on MEG7 vince. I can't restart my phone because every time loses the baseband and sim detection. My rutine to get back is:
1.- Flash via trwp a shared good one similar EFS partition backup. With this step I recover the baseband and the sim detection BUT the status of SIMs are "radio off" don't have signal and can't do calls. (the IMEI remains despite the lost baseband)
2.- Flash via QPST a xqcn backup ( I founded 2 files on google). Reboot the phone. Sometimes the signal and baseband come back without problem BUT sometimes I back to the beggining, without baseband and sim detection. It's really annoying.
Now I have obtained a modemst1 modemst2 and fsg images of a identic model. My question: how to flash it? with twrp? fastboot? adb?
Thanks for the suggestions.
I'm facing the same thing but only on 2nd sim slot. The 1st slot work flawlessy. Switching sim card doesn't matter.
It recognizes the operator and imei but signal is gone!!! I've tryed everything, flashing miui 9.6.4, 8.8.2, via fastboot and test point!! Relocking bootloader... flashed 00000080_0.xqcn as well.
nothing has worked.
I haven't tryed your solution, can you share all files needed? Thanks.
Anyone can help me?
I don't think it's hardware issue, because Sim's operator is recognized... But signal strength always show -1dbm 99 asu, whatever I do in network type (global,LTE etc..) and only on 2nd slot.

Hello all. I am familiar with LG Aristo 2s and the like, but not so much with LG V30s.
My buddy has an LG V30 H932 T-mobile version and he has forgotten his PIN.
I would like to recover his userdata, then reset the phone and possibly even root it.
I used a modified LGUP utility to make complete partition images on my PC, including all these:

Anyone familiar with how I could go about mounting and decrypting his userdata partition ?
I am very tech-capable--I have even created ROMs for the LG Aristo 2 and 2 +.
Thanks very much if anyone can help. My buddy has a bunch of un backed up pictures on the phone.
If it is truly encrypted with a PIN, then I am pretty sure there is almost zero way of recovering the data I am sorry. I certainly would not want it to be recovered trivially - that's the point.
Out of the box all Android devices are designed to backup data to the cloud - which is where data should be safely stored. If you turn that function off your need to find another method of recovering in the event of loss of access to the phones and it's local data . Data on the phone is effectively just a local cache to lower the latency of access, and mean you can keep using the phone when it is offline.

@Fisherman1,
Yes of course I understand the concept of data backup and cache, I just remembered being able to mount an encrypted userdata on an Aristo 2 using ubuntu in the past. However, I'm unsure whether it had a PIN or not.
It seems like I used encryptable=/path/to/backed/up/encrypt/folder or something like that, but I am probably not remembering it correctly. Also, I didn't get the data until backing it up was no longer an option.
Thank you very much for the help, my friend

if you follow the guide I posted, youll be able to recover
All you need is the radios for the security patch you've flashed and reflash those. You didn't mention anything about the update your on. But there are radios for at least one security patch on here and you could get more help in the OnePlus Nord N20 telegram group

Here's your firmware

Bro did you ever get this fixed I did the exact same thing I lost my radio then with my luck I ended up flashing the wrong opf file and to add the cherry on top I had my phone connected to a bad USB port. I moved my phone just enough to make it disconnect while it was flashing left my phone on a annoying boot loop .
Butttttt within a couple of days I got my one plus running like new and rooted. ALL thanks to a OnePlus guru here (ahh @dmtec instructions where spot on (just saw his comment haha he's the guru I'm talking about)) in xda.
If you need help restoring your phone let me know. I don't mind helping out.

all you need to do is flash the modems that match your system and radios will work again even if other partitions dont match as long as it boots though u may have issues with fingerprint and stuff like that if other partitions arent all matching.....

Finally got patched LGUP to recognize the phone and was able to use partition dl mode to see the partitions on the phone and also the partitions in the rom I was using. Looked like it was going to let me dump all the partitions from the phone and flash all the partitions from the rom on to the phone. Clicked start and window popped up asking me to select the partitions I wanted to flash. Can I just "select all" and flash the whole rom that way?
Edit: Phone shows it's connected and ticked partition dl mode in LGUP and tried to dump all partitions but it starts and then throws an error at 4%.
Update: So it seems that the phone won't allow LGUP to dump or flash files unless SID_A and SID_B are deleted first which has to be done in QFIL. Is this correct? Also when I do attempt to flash the new rom should I uncheck and keep the original FTM file instead of deleting it and flashing the new one?
