Hello All
I have strange story to share. After 5 years of using rooted Xperia Z3 compact I brought Xperia X compact and I wanted to root, debloat and use. I did know about loosing DRM keys after bootloader unlock so I made a TA partition backup. After some time tinkering I had a success, fully rooted X compact, debloated so I put my operator sim card first time in the phone and sim card was detected, but I had no service. I googled about this issue, but was not able to get it running. I checked also with friend's sim card, but same result. I also tried reflashing stock 8.0 and stock 6.0.1. Still no service (up in the tray just empty triangle)
I was thinking that there have to be some kind of hardware problem. I never found a mention here in xda forum, that I can loose ability to phone by unlocking and rooting.
So, only thing to try was to relock bootloader, restore TA. I tried today, after xperia companion repair I ended up with stock 6.0.1. and to my big surprise, after putting my sim card in, it was detected and I have signal. Everything seems to be working. Phone calls works too.
What can I do to have root and also can connect to operator and call properly ?
What in the process of bootloader unlock and root, flashing several times could have caused this ?
Does somebody have experience like this after rooting Xperia X compact ?
Thanks

I have had strange issues after flashing roms before, but usually a re-flash fixed it. I guess if you rooted again, it would be OK this time..

Hello.
Thanks for reply.
Not in particular. One advice to try it again, but right now, the xperia x compact is my only working phone so I am using it without root. My old Xperia Z3c developed nearly similar problem, no reception at all, but in this case it can be hardware failure. That phone was used 5 years and it is falling apart.
I will definitely try the root again later, but don't know when.
I was hoping for someone with same issue.

Hi guys,
I recently picked up a used S4 on Craigslist for cheap because the guy "screwed up" using Odin and flashed something that caused his phone to not register on any networks. I figured, what the hell, it's cheap enough and I might be able to restore it. So far I've restored the Rogers firmware over Odin and tried installing a custom rom/recovery too. I'm still getting this problem unfortunately. The IMEI reported with *#06# and in the status screen does match the sticker on the inside of the phone.
So I'm sure everyone's going to suggest that the phone was stolen and the IMEI has been blacklisted. My provider (Fido/Rogers) apparently doesn't care if the IMEI is blacklisted, they'll let it run anyway. I called up Fido anyway (since I'm a Fido customer) and asked them about the IMEI of this phone and they say they don't have any record of anyone calling in reporting it stolen and they don't have an IMEI database so she didn't have much to say about it.
Does anyone have any other suggestions? I've also flashed just the kernel, and I will flash a modem onto it too. I know my SIM card works, and both my SIM card and the last owners SIM cards don't work. I know the radio works because it picks up the emergency signal fine, and the SIM tray isn't damaged because when I put in my Fido SIM the Fido APN's automatically come up, as well as the lock screen goes from "No SIM inserted" to "unregistered SIM." Could my EFS partition be borked? Wifi works and IMEI shows up correctly.
The buyer said he would take the phone back if I can't fix it, but I want to try a bit more before I give up. If anyone has any ideas or suggestions, that would be great. Thanks a lot in advance XDA!
Summary:
-Used S4
-Owner flashed something wrong in Odin
-Gets "Not registered to network" error, unregistered SIM error
-Tried restoring
-Tried new ROM/Recovery
-Carrier says IMEI is fine, also tried directly registering the IMEI to my account
-IMEI is correct in settings/sticker on back of phone
-Wifi/everything else all works
Sounds like it's SIM locked to a different network. Try the the guide here: http://forum.xda-developers.com/showthread.php?t=2285431

My girlfriend has a Bell sim, which when we insert, gives us the "Please enter unlock code" screen.
My sim does not do that. I know this device is for my carrier, but I figure the easiest way to get this going is to just unlock it and see if the problem persists on other networks.
I've tried that unlock tutorial before. The first time I tried it, when I just got the phone from the previous owner, it said "Golden-backup does not exist" so I couldn't do the restore step of that guide. After Odin-flashing everything and starting over, I can't even get into the UMTS menu anymore! I'll try another restore and give it another go though.
Edit: Another problem. I did a restore again using Odin and notices that it never properly wipes the phone. When I finish flashing, my Wifi still autoconnects on first boot, and every few seconds, a process crashes causing the phone to freeze. Has anyone heard of this kind of problem before?
Quick update:
Managed to Odin-flash it to the earliest firmware I could find for the phone without any crashing or freezing problems. Trying to do the network unlock method mentioned online. It does not work, even though I'm following the instructions to a T. Could it be that my EFS partition is borked and that the NV rebuild can't happen, meaning my radio configuration would also be borked?
Edit: Oh and when I booted up my phone for the first time, the phone was actually ON Fido! But within a few seconds, it went back to "Emergency calls only."
Hmm, that is some odd behavior, and definitely not a carrier lock. Shame it's never that simple to fix.
Not quite the same as your issue, but I lost my ability to make and receive calls after flashing a newer modem on an AOSP firmware. Flashing custom kernels, older modems, the latest stock rom and kernel were no help at all. I tried everything I could think of short of groveling. In the end the only way I got everything working again was to flash the original factory firmware my phone shipped with, factory wipe it from stock recovery, then flash it again. If you've already tried that (and I'm guessing you have), consider contacting Samsung regarding warranty. They've been really good to me in the past, even with second-hand phones.
I can confirm that Odin doesn't clean everything out. In my trials I also noticed that flashing via ODIN without a factory reset presented no setup wizard, caused lots of FC's and left some previous files hanging around.
Sounds like a bad sim tray.

I had trouble with my handset after it got run over in the street, making it's otterbox earn it's money. The only bad symptom after that episode was Emergency calls only kept recurring.
I cut a tiny square of transparent scotch tape, avoided touching the sticky side, and placed it squarely on the SIM chip's backside, to make it fit the sim slot more snugly. It sounds like you should try stacking two or three layers on your chip as it sounds to be more loose than mine is.
Hi everybody! Thanks for all the help trying to fix it! It ended up being that the guys the previous owner had unlock it used the debug-menu unlock method and my phone was one of the ones that doesn't accept it. Lots of other people complained about similar problems as me in the free unlock method thread. In the end, I paid for the FastGSM USB Unlock method and it fixed the problem.
OH MY GOSH YOU JUST SAVED ME from buying another phone!! THANKS so much.. I added 3 layers of tape on the back of my sim and it works!!! weird.. cause I have the Dual Sim.. and it was the first sim that would not work. the second sim was fine.. anyways.. THANKS SO MUCH!!
I have the SM-G930P with software version: G930PVPU2APC5, however I'm using a cricket sim card. I was able to get it sim unlocked via remote tether using onlineunlocks.com but I'd like to root it. I lost root when they unlocked it and I'm guessing the unlock only works with stock firmware. If any of you know whether I can still root it I'd really appreciate you chiming in on this.
Thanks!
The remote unlock I had done by gsmzambia.com hasn't been effected by rooting or flashing other firmware. I've switched back and forth between P, T and U firmware without losing my SIM unlock. I wasn't rooted at the time I had the unlock performed, but assuming that they use similar methods to do the unlock, they probably had to flash a custom Eng bootloader, which I'm guessing is what killed root for you. The only thing that's ever re-locked my phone has been putting my Boost SIM card back in it. Apparently, using any Sprint-based SIM card will re-lock a 930P.
Thanks!
Thanks! I rooted it and it's running great! Also in case anyone else sees this and had a similar question, I'm 100% positive that ApexPredatorBoids is right. It really is that nothing should undo your unlock, except putting a sim from the original carrier back in! I also performed I factory reset through recovery mode since I messed something up after rooting and it obviously again had no effect on the sim lock. I personally couldn't find a straight forward confident answer on this subject with my searches so this was really helpful.
What did you use to root?
I just got an LS997 V20 and so far I'm really liking it.
However, since I'm using it in the UK, I needed to network unlock it. after doing this, I hoped that I could use my simcard, however (as you can see in the added image) it still shows a simcard error. the simcard works, however since in my other phone its being recognised.
I think I read somewhere that the sprint ROM blocks simcards that aren't Sprint. I tried to unlock the bootloader and fastboot, but haven't been able since I accidentally installed the latest updates. is there any solution available or so that can fix it without needing root or the bootloader unlocked? I really want to use this V20 as a phone and not as just a camera and mp3 player
Is there any way to fix it?

If you have updated your phone to August OTA. Then you will be left with no other option than to purchase a sim unlock.

I already bought a network unlock that went via an app. I bought it from lgsimunlock.com . Any other ideas? I'm not even sure if that network unlock worked...

I'm in the same shoes as you..Got my phone updated till August bought a remote unlock but didn't work.
I don't know whether phone unlocks no longer works on LG LS997.
Has antoje found a solution to this? I also have the same issue
Hi all,
I have a problem with my XC, i hope there's someone here who could help me out with this .
I get a SIM card error when i start the phone. After a while (5-10 mins) the error transforms into "No Service" as if the phone now detects the SIM card but has no service whatsoever.
Things i did to my phone prior to this:
- unlocked bootloader
- installed custom recovery
- root
- installed custom ROM
- drm fix
The phone did function properly for a few months actually after these operations without a SIM card error even once. But then i tried to install custom ROMs again (and i'm sure didn't flash ROMs not suited for XC) -actually tried to install "existenz" ROM but i did get a bootloop so i -once again- did the usual procedure with flashtool and flashed a firmware to set everything back to stock as close as possible. That was, when i started to get the SIM card errors. After several restarts (cold and warm) the phone sometimes recognized the SIM card and i could use the phone normally. But this was true only till the next restart, where i got the same SIM errors again.
Things i tried:
- flashed several different firmwares (official) with flashtool (wiping everything) - all the newest firmwares.
- *#*#72786#*#* in dialer to wipe carrier settings
- *#*#4636#*#* in dialer to go into phone settings and changing those settings randomly
- flashed another AOSP based custom ROM instead of stock sony
- wiping and formatting everything between the flashes of course
- cleaning and re-inserting SIM card (which i never took out before anyway)
But unfortunately nothing worked. Phone keeps to not recognizing the SIM card (which is working just fine in another phone). Everything else works just fine on the phone. The IMEI is displaying correct. I'm almost certain that the fault isn't hardware-based (i didn't drop the phone or exposed in water etc.) but software-based. Did i just managed to brick my phone by flashing something related to the modem which i'm not aware of?
I can't find any solutions on google, which help me, which is why i'm posting it here. Sorry for the long post.
Did anyone experience such an error and/or knows what else i could try to fix this? I hope for answers
Thanks in advance!
Anyone?
I've got the same problem.
I didn't unlock the bootloader or anything prior to getting the bug.
I wanted to downgrade to nougat, because aparently it helped someone in the forum below, but I didn't manage to do it.
https:// de.ifixit. com/Antworten/Ansehen/468864/Sim+Card+not+picking+up+mobile+network.+Possible+software+issue+(Oreo)
Did you try nougat, when flashing different firmwares?
Your post makes me question if its worth it, trying to downgrade.
Try to remove sd card if you have one. then restart the phone and see if sim card is recognized.
I had the same problem and I think it was a hardware failure in the end.
I also tried almost all the things you were writing above. In my phone it started slowly. Sometimes the SIM was detected but after some time the connection was lost.
It happened some time after I installed a new battery.
But since there are no original batteries available for the device anymore and the new battery was even worse than the 5 year old original battery, I gave up investigating the SIM issue and don't use the phone any longer.
I bought a new (used) x compact because I still like the size and I saw some development was going on for this device.
In the end I cannot tell whether the SIM was not detected because I broke something while changing the battery or due to age of the phone but I think it was a "normal" failure.
I also read from others that they had the problem and the SIM was working for some time after I switched the battery before it stopped working.
Nevertheless. Good Luck to you. Maybe it is something different on your phone.
So i have the smg935p but i am new to flashing roms and have been learning trial and error. I initially flashed a custom rom to the 9bit amd essentially soft bricked the phone. I did more research and flashed the stock rom(or so i thought) now my software version is G935AUCU8ARJ1. I have since had the phone unlocked by spint but now every sim i put into besides the original is showing invalid. Any ideas as ti what i can do about unlocking this phone to any carrier? I am currently using straight talk which i never wouldve switched if id known about the hotspot issue. Also if anyone knows how to bypass that issue that would also be wonderful. Can i perform this unlock or task of doing such without a computer?

If you previously owned it, you can try contacting Sprint to get it Sim unlocked. You might have better luck finding an unlock service on eBay though
