I just got an old htc ph39100 and it met some troubles like this. After rebooting, it usually lost imei and baseband so my phone has no service. But if I try to reboot many times, finally it has service and Imei and baseband too. But if I turn off or restart my device, it has same troubles again.
I tried to flash RUU file to come back stock rom but it doesn't solve the problem
So anyone can help me to fix this?

Check your Sim card slot... Make sure your card fits tight... Maybe push down on the metal that the Sim card rides in

I checked a lot of times but no luck. I just wondering if it's sim card slot problem, so why my device doesn't recognize IMEI, baseband? After many many times try to reboot, some how it have service again and IMEI and baseband appear. But all of them were lost after rebooting.

SIM stands for Subscriber Identity Module....
If the information you are talking about is missing... Its usually because the gold contact on the card isn't making a connections to the gold pins in your phone... Especially when its intermittent...
Try this...
Take the back cover off the phone with the power off... Push down LIGHTLY on your SIM slot and hold it... Then push power... If the slot is under the battery... Try a little shim under the battery on top of the SIM slot... We are just trying to push down on the card a little...

My phone just suddently stopped reading my simcard. the sim card works on my fathers phone, Please help me what can i do i really need to get it working
It could be as simple as a dirty connection on your phone.
Use a clean dry cloth and VERY CAREFULLY clean the six points on the phone that make contact with the sim card.

i've tryed that but it dident help, ive heard its a strange bugg that deletes the IMEI nr from your phone
Try using your father's sim card in your phone....
If it works fine: Get your sim replaced.
If it does not work, get your device checked.

i had a similar issue, first one it was my fault, i inserted my sim card wrong...if you're wrong your simcard will plug correctly but does not work.
About the issue you're talking about I had a problem with imei and wifi and BT adresses.
It's an issue of the ROM that does not read the /efs/nv_data.bin correctly, because all data included in the efs folder is read only.
I just installed a stock rom to have a confirm of this thing and it was.
It's always raccomended to backup efs folder before any flash
try to change a rom .
Phone will not recognize sim/ imei "Unknown"/ baseband "Unknown"? *Updated*
Updated title because problem has now changed.
current problem--
Phone is stock, randomly stopped getting signal factory reset phone using keypad, now phone will not recognize sim card, the imei is blank and the baseband is unknown. Tried reseating the sim, and powering on off.
initial problem--
After having a problem free note for some time now it randomly stopped working. I cannot make a call/ text or use data but the wifi works and the phone functions outside of those uses. When making a call I get various errors in the form of Mobile network not available/ Not registered on network and when i go into mobile networking settings> network operators it takes a while when searching and tells me to either try again later or gives me a message "error while searching for networks." When i take the sim out all together I get bars of service but when the sim is in it either gives me a circle with a line through it or a empty signal bar triangle.
I called straight talk customer support as i thought it was a problem with the service and they told me I had a bad sim card. I have since checked the sim in another phone and it works fine. I have tried multiple working sims in other phones and no luck in mine. The phone appears to be recognizing the sim as the apn settings are adjusting based on what sim i put in. I have tried to take out the battery, take out the sim, factory restore but nothing seems to work. I have also checked the imei number online to see if it was blocked or something and it said it was not. I took it to a local phone repair shop but after toying around with it for a hour they didn't know what was wrong, so here i am, hopefully someone can point me in the right direction. thanks.
May be the phone is network locked. is it asking for some kind of key or pin anytime or when restarting the phone?
where did this begin to happen?

I know the sim isn't the problem as it works in another phone.
You may want to try flashing stock GB with PC Odin...then with stock GB recovery do a factory reset.
Don't do anymore factory resets if your on ICS and completely stock - you will kill your device...see the brick bug sticky

I'm assuming i have to root my phone in order to look at this folder? I'm looking into this now.
yes.
when restarting phone do you get the password prompt for the sim pincode, could be sim is not registered?
Anyways a stock phone should not do this. Its a case for customer service to fix efs. That appears to have instantaniously corrupted(!) first case I have ever seen of this.
Almost cannot believe it.
Without sim, is the imei there? I am suspecting your emei was gone before which you never noticed then. Is it even a new phone?
note rooting might void warrantee, so be careful

Well, I'm not sure about the problem; if you are on a custom rom, it might be because of that, or incorrect flashing. Try using another ROM, and if problems persists try Stock ROM meant for your region. (it might be possible that you flashed a ROM for a different region and because of that you might have a problem..)
AND NEVER POST YOUR IMEI NUMBER ONLINE.

Thanks for the advice about IMEI number, i didn't think of that because i went crazy because my phone doesnt work.
I'll try with stock rom.
I flashed original stock rom on the device, but the problem remains. Does anyone know the solution, I am going crazy

pop your sim card out for 15 min. then put it
back in your phone.
In the second pic it is clearly showing 1 bar of signal
So how can you say sim is not being detected
No way out here

Thanks for the advice, but that didn't work. I tried several SIM cards. Same thing every time.
have a read tho these answers, maybe you'll find a solution http://bit.ly/17Ku2cc
I just got a used AT&T Vivid with what turns out are 2 anomalies that I failed to observe initially.
First I tried to put my ST sim card out my AT&T SGS, and get no service. No big shock initially since I have to change the APN info. Couldn't do that cause option is dimmed.Checked further, No IMEI, IMEI SV, or baseband. Took sim out and observed that I get NO sim error at startup, just "no service". Tried an AT&T sim from a friends Vivid, same result.
I was hoping that the sim card reader just might be bad, a cheap easy fix and apparently some what of a common issue. Haven't ordered one yet until I get more info on whether the no sim error and no IMEI etc are related and it's not a more serious hardware issue. I don't have a problem with repairing hardware if needed.I'm a noob here, but have a brain like a sponge, so any thoughts on how to proceed with diagnostics would be appreciated. Thanks in advance
No imei is really bad...
No one here can help you recover it without a proper backup... I have no idea how to back it up nor restore...
If you don't figure it out I'd have to suggest flashing to stock... prolly via ruu and go to an at&t store...
Sent from my Vivid 4G using Tapatalk 2
I don't think (but don't know 4 sure) that this phone is anything other than an out of the box stock configuration. I don't have service with AT&T so I don't know how much help they would be. I did check with them to make sure IMEI printed on the phone wasn't blacklisted and it's OK. All I have done was to do a factory reset to clear all the PO's stuff.
Does anybody have any more ideas? I am wondering if I don't need to replace the motherboard and or just the simcard/sd part. Changing the motherboard would mean a different IMEI right?
No imei means something went wrong with the bootloader. It's unlocked? Did you try to S-OFF?
I believe flashing a rom stock via RUU (that's it, flashing the PD.zip file) maybe can fix the problem.
At worst you must change the motherboard and yes, you will have a diferent imei.
I may be wrong, but I see no sign that anybody has done anything to change ROM or anything else on this phone. I'll try to do a S-off, and unlock it since I want to use it on ST anyway.
hello,
i've also same problem here
flashed with stock rom but no luck ,
bootloader locked and s-off
searched forum but no success story
i think i'll return it
Well I finally got a new SIM/SD card reader and installed it. No change.Tried ST, AT&T, and T-mobile sims
Still get no SIM error when booting with or without a SIM card, has an X on signal strength, and it doesn't even say "no service".
Same as to IMEI etc. info, nothing shows up.
Am I going to have to change mainboard? Or is it possible firmware/ROM changes could fix it?

Unlocked the bootloader tonight, no problem. Will try s-off tomorrow.
Where can I get a stock rom file?
I'll only ask this dumb ? once: Is the OS (JB,GB,ICS) different than the rom? I'm still running gingerbread 2.3.4, should I got to ICS or? Will that have any affect on the imei issue?
I might just be getting some experience with this phone if I have to do it all over with another mainboard.
OK, so I decided to play with this phone again after my SGS1 was freaking out yesterday. I finally found and used a phone dialer code do download the ICS update, and it downloaded (via wi-fi), installed and rebooted fine. In fact It apparently fixed my IMEI and SIM card problems because when it booted the first time with ICS it showed a big icon "no SIM installed" ya hoo!! checked IMEI in settings, all was good. Played around with settings/menus a bit to familiarize myself with the differences, then restarted...NO IMEI again, and no sim error without any SIM installed On the next 5-6 restarts it worked fine all but once, (total on time of around an hour) but now every restart (10+) it's back to same original issue: no IMEI shown and no SIM error. I still have no AT&T compatible SIM card to really test it but if it doesn't give me a SIM card error (no SIM card installed) it's a moot point.
It really puzzles me that it appeared to work at all if I have a bad mainboard. My daughter in-law has a Vivid with a bad screen she's going to give me to use for parts (mainboard) but I'm not sure if there's not still some hope of salvaging the current one.
Comment, thoughts etc... Please
Okay, I posted this question in the I9300 Q&A section by accident (was a bit distraught, didn't read the section title properly), but for some reason a mod appears to have deleted the thread instead of moving it, so here it is again in the correct section.
So after using my I9305 for about 8-9 months now, I woke up this morning to find my phone nonoperational. The phone requests on boot a "SIM network unlock PIN". If this window is dismissed, the pulldown notifications drawer states "Invalid SIM card" with subtitle "Network locked SIM card inserted". Quick Googling reveals that these notifications and errors typically show that a phone is locked to a specific carrier. Now that's understandable, but this phone is unlocked, and I hadn't even taken the SIM card out until this error occurred. The SIM card works just fine in another phone.
I've tried rebooting the phone (first port of call), and using the code *#197328640# in the dialer to SIM unlock as per this post (but I didn't have "[4] NW LOCK NV Data INNITIALLIZ" as an option). I tried using "busybox chown 1001:1001 /efs/nv_data.bin" in terminal emulator as root, after seeing this post, but it came with an error of "chown: /efs/nv_data.bin: NO such file or directory". So... how bad do things look? And no... I don't have a backup of my efs. =[

Since then, I also tried *#06# in the dialer, and my IMEI is intact.

Not sure why doing anything with the battery would be in any way related with the SIM. I also forgot to mention that I had already tried cleaning the SIM card at the start with alcohol. In any case, the SIM card works fine in another phone, so it appears that there isn't problem with the SIM card. In any case, I managed to RMA the phone, now the long wait to get it back...

Got my phone back from the shop today. Kept an eye on the shipping tracking when I sent it out, and they sent it back out half a day after they took delivery, so I'm guessing they used a SIM unlock code since it's definitely my phone that I got back. Didn't have to pay anything, so I'm happy. Still not sure why/how the phone decided to lock itself though...
