[Q] phone refuses to read sim

I know there is another thread on this but none of the tips resolved the issue. so today i flashed cm10 with devilkernel and the modem got wiped. so naturally i flashed a new one. It said it flashed but didnt work. so i wiped it and tried another. this process repeated for 3 hours and my friend rhine, who is highly skilled with this, and i together could not get anything to work. there is no lock out message but once it said safe mode although that went away. thanks in advance.

Have you checked to see if your IMEI is correct? I haven't heard much about it recently but when Jelly Bean first came out people would randomly have their EFS folder wiped when flashing to JB. Compare the IMEI listed on your phone under the battery to the one listed in the settings menu.
If they don't match then your best course of action is to use a one-click and take your phone back to stock which should restore your EFS folder. I would suggest then making a backup of that folder and then move forward with flashing as you've done before.
Some people say that removing your sim card during the flashing process will help prevent any issues but I've personally never had this problem.

Removing the sim fixed and reflashing the modem worked for me. thanks!

IMEI loss after flashing to CM11

Hello everyone,
i flashed CM10.2 from the FreeXperia Project on my Z1 and it worked fine,
but the camera was very blurry and didn't take pictures at all.
So i decided to flash CM11 (also from FXP), the camera worked damn fine,
but now the IMEI is set to 0 (and IMEISV to 26, if thats a matter).
Without the IMEI my provider is blocking my access to UMTS and mobile
connection, so the phone is pretty much useless.
So my question is - is there a way to set the IMEI or flash it in from previous backups?
Thanks in advance
Ps: Sorry, forgot to mark it as a question and can't do it from editing.

Ok, i got the settings back by doing a full wipe and reflashing the stock rom.
Now i try to find a tool, that makes a backup of my efs-partition and is able
to restore it on cm11, if the IMEI is getting killed again.
The only tools i find for this are for other phones (though not safe for z1) or
not from reliable sources. Does somebody know a tool like that?
Thanks in advance

I heard not heard of such a tool for the Z1. I remember reading about IMEI 0 some time ago, but don't remember many details. Search more, it's been mentioned before. You may have to go back to a stock FTF to fix it.

PSA - Never flash another device's persist, IMEI loss understood

Hi all, I've seen that there are a few threads in this and other forums that are saying that using a particular other persist will help restore IMEI, Volte, or other lost functionality after installing a custom Rom and reverting back to stock nougat. As this sort of suggestion has resulted in many devices being permanently broken, I'm sharing a thread I made in potter.
Fix Persist, resolve IMEI=0, Explanation, Requirements
Now, the most important thing here is to NEVER EVER flash another device's persist. Your persist contains key files that have your IMEI data (in encrypted form), and it will not work with another device (or vice versa). In the thread above, I explain what has been happening, how to detect it, what can be done to fix (note - this may differ from device to device - I recommend not applying the fix until after other who have 'fully working devices' can confirm key details, such as the "rfs" user), and why other persist files gave the appearance of working (but were actually causing permanent damage).
Also note that the fix is for stock nougat. I have already seen in the cedric devices that the upcoming Oreo may apply the same type of fix on boot (i.e. changing ownership of key folders and files).
Happy to answer any questions if people ask. Please keep questions for this device in this thread.

Is there any hope to fix IMEI 0?

It all depends on what you have or haven't done. If you flashed another persist, you're out of luck. If you haven't flashed another persist, back it up now and save it to the cloud so you never lose it. Then the principles in the guide may help. You can see if you are affected or not by following the section 1), as long as you are on a stock nougat rom.

Dude , thank you so much for that thread and Info. Finally someone is starting to explain the root cause of this IMEI/4G/Volte mess in our devices. Unfortunately I got my phone second hand and the dude had flashed a lineage ROM on it. He had mentioned radio problems but has said he had flashed the wrong modem and fixed it. The phone was 100% operational with the Lineage ROM he had on it so I didn't think much of and I figured since I've been rooting/flashing my phones since the day I got my first android, I could deal with it anyway. In any case, I soon went to flash an 8.1 ROM and discovered my IMEI gone. Eventually I found a few 8.1 ROMs that worked and I'm completely happy with AEX 5.2 which I'm on now. I have the EFS and Persist backups as of the moment I acquired the phone. I wondering though if there is a way to tell if my persist is the one that is supposed to be there or if the owner flashed a different persist? Also when I input the terminal command from your post it returns a list of folder within persist but no ownership tags as shown in your post.

I think the only way to tell if the persist is definitely the one for the phone is to revert to stock nougat, follow the guide (I did find that one of the posters in the thread tried it on their sanders device and it worked for them - fortunately there is enough consistency so that the guide applies to many phones) to fix the folder ownership, then erase EFS and reboot. If your IMEI comes back, you're in luck. If it doesn't, hold onto your EFS backup for the rest of your phone's life!
(Also note that reverting to stock nougat should be done carefully. Don't downgrade the bootloader, otherwise you'll run into other problems..)
Also, just to emphasize, the output from the commands that list ownership is taken from nougat. Oreo has changed things, so it's not surprising if you get different things. E.g. Cedric's Oreo appears to not have an rfs user, instead it is using something like oem_2903.

Just wanted to chime in and say that this has fixed my phone! I've had iffy VoLTE and other issues since going back to stock and couldn't even use custom ROMs since it wouldn't allow me to search for a network. This seems to have cleared it all up. Thanks!

thanks a lot. I've had no lte data since the day I got the phone, but thanks to this it is fixed.
edit: for verizon peoples who only had 3g, I can confirm that lte still works after flashing at least msm xtended so probably other roms too.

any solution to this problem, i installed this rom and now baseband is not found and imei zero

Folks, the rom above was a test version of the Oreo soak test that I made. Unfortunately it seems the is an issue on the build. I have pulled it for now. Hoping that a downgrade to stock nougat will help fix it. Goodness knows I'm trying to help with the IMEI issue, not contribute to it *facepalm*
Edit: user got everything back by flashing a nougat twrp flashable build. So issue was definitely just in that particular Oreo build

Can anyone confirm if this should work on the g5s plus with those commands? It doesnt seem to for me

I can confirm it worked on my xt1806.
Back up the EFS, run these commands, then run the fastboot commands to wipe your modem. It will rebuild and you should have imei back

Can you check if you have a file dhob.bin.bak after running the find command in the post? Many people who don't have success with the guide are missing that file.

I have successfully executed this procedure and I got a hd calling option or an hd calling icon..is that correct??. Then I backed up the efs and again i got to custom ROM then and flashed the efs partition but no sign of volte or can't make call from Jio...
The question is can I use the efs partition which I recovered through this on a custom ROM?

Answer as per the other thread:
Yes, I get an H+ icon on my phone, so that would be what you'd want if the procedure worked. If Volte doesn't work on the custom rom, then it's a custom rom issue.

my volte worked without restoring the efs... just fixed permissions from stock, flashed rom, everything worked.

Bro how you can fix the volte can you tell me?

just flashed stock and fixed the permissions like op said. when i rebooted everything was fixed and still works with at least gzosp-based roms and probably others too. no tricks needed.

Thank you bro...it's worked backuped the efs and persist partion on the stock ROM and again flashed pe ROM and reflashed the efs and persist volte is now working fine thanks....

is there a way to get this post pinnedor something?

Hi guys. Reported success earlier in the thread but my issues came back. IMEI is there, everything functions properly in stock, but in non-stock I get an "error searching for network" that I didn't get before I flashed a broken gapps file that edited my persist file.
I know my persist partition is currently stock, and I'd like a copy of a working persist file from an xt1806 that I can copy my known good persist data to. Thanks!

Phone has no LTE, yet still has imei, 3g data after flashing rom.

I have a G5S plus (xt1806) on sprint. Every rom I flash results in me not having LTE, and 3G cuts in and out unreliably. I have checked and my imei is still there. I have flashed the modems, and I have restored my efs backup to no avail. This has happened on every rom, no matter if I clean flash, dirty flash, I end up with the same result. Does anyone have any insight on this?

I had a similar issue on Verizon. When I got the phone I never inserted my new sim card & connected to the network before I unlocked the bl, flashed TWRP, custom ROM, etc. Every ROM I flashed had the same issue as you describe in your post.
Solution: I backed everything up to a pc & fastboot flashed back to stock & started over. Everything has been fine ever since.
***Keep that efs backup you made too - just in case you lose IMEI on your return to stock; efs restore should fix it.

Yea, I've tried reverting back to stock. I get back my service after restoring efs partition, but whenever I do it again, service is broken. I am at a loss.

Fwiw - I worked with another Sprint user a while back who could only get reliable service with the original firmware - that which came with the phone when purchased. Fortunately he had a bu of that and it was the only thing that worked. There is a thread about checking/fixing permissions on your persist partition that may help. Check it out - ya never know.

I really dislike how sprint deals with unlocked phones, they never play nice, I have had carrier specific issues with them in the past. If it wasn't for my grandfathered truly unlimited plan I would switch in a heartbeat.
And yea, I'll be sure to check that thread out, thanks!

I had initially had this in my previous reply - Sprint has always been special - but I deleted it, should have left it in. I've heard many bad stories from Sprint users in the past, going back years. Just glad I always stayed away from them (they have no coverage in my neck of the woods anyway).
Good luck!
PS - the link in the above post has the instructions to set correct permissions on affected files in persist partition - they came from the thread I mentioned.

Unable to install other ROM after custom from in TWRP

I recently installed Project Elixer custom rom on my Poco M2 device, everything worked fine. However, calls and sms are not working, I tried a lot of things but no good. So, I decided to go for other custom rom like PixelPlusUI, but when I went to twrp and tried to install it, shows me error -> ERROR 1: unable to extract rom.zip, I tried other roms and versions too. but same issue, so I guess this is something wrong with my system instead of roms. I am really stuck without sms and calls pls help me

For the sms and calls problem...
Did you make an IMEI Backup? Because is the most common way of lossing mobile services, if you did make a backup, just restore it in TWRP, if not, you're screwed, is impossible to restore the IMEI completely without any backup.

Hey there, thanks for helping me.
I want to give you an update.
What happened is that I took the backup when my phone was working fine, however my pc got resetted and I lost that eventually.
After reading your post I was totally scared that I nuked the phone.
And the info was correct, w/o backup, if IMEI is gone we are screwed.
However, a friend of mine helped me and told that the issue is not with IMEI, so I somehow managed to boot back into original rom.
Thanks a lot
