[Q] No SIM inserted

Well, I have a OB with the "No SIM inserted" problem... (with SIM from the network lock or any other)
Any idea how to fix this?
Just tried pretty much any trick I could find online (just missing the heatgun thing - in due time...)
I appreciate more ideias.
thx!

If it doesn't recognise any SIM card it's hardware problem I think...

Btw i had the same problem....it got fixed in some store and the problem was something called main pcb

I know it is most probably HW... but, doesn't hurt to ask for opinions/ideas.
Right now I only have a cool media player
I think I might try the heat gun trick and see how it goes.
[EDIT]: Could it be black listed by the operator? (I got it as is, used)

Hi, I've got this same prob but with another phone, non-android it was a samsung gt-s5560 [marvel or tocco] it was mine and I sell it, after a few days the girl keep telling me that she couldn't use the phone cause of a PIN, does your OB ask for a PIN? if so, just ask the old owner, when I remember the PIN call the girl and now she's happy using the device

I had the same problem with my ob. I take it to service and they replaced the phone with a new one. It's an hw problem with pcb.

I guess taking it to service won't do 'cause I don't have any receipts of the purchase (it was used and I know about the issue).
Yesterday I tried to check the connections to the SIM reader module but no avail.
Maybe today I'll try to toast it with the heat gun.

If your phone asks for PIN when SIM is inserted then it's probably stolen and was blacklisted in international base of stolen phones used by operators worldwide.
If it isn't asking for PIN then it's 100% hardware fault. Better take it to some electronic repair service, because with the heatgun you can make it even worse...

I had that problem before. I think it's software-related (or maybe just a fluke). My OB is running on Nova 4.5.
I always use "network sim #1", but when I switched to my other network sim, which we'll call "network sim #2", it was ok for a couple of minutes then after that "NO SIM INSERTED" appeared.
After that, I rebooted and noticed that my phone was unusually slow... I still have the "NO SIM INSERTED" on the display.
I rebooted again and my phone still was slow and "Force Close" prompts appear one after another.
So I just re-flashed Nova 4.5... I didn't take the SIM out. And voila! 1 month and no "NO SIM INSERTED" messages again.

Not stolen. Not blacklisted. Just won't assume any SIM. From my searches this seems a pretty common issue that can strike at any time... (You are warned...)
I know the heatgun can easily kill it but I'm willing to take the risk. In other phones replacing the SIM reader module would fix it but the P970 is somewhat welded/glued to the shielding in the MoBo and I couldn't find a replacement part also.
Anyway, I bought this with the hope I could fix it, otherwise it'll be a cool media player and a nice development platform addition to my other android.

As of now, don't think its SW related anymore... I've flashed Nova (v8) and CM7 (n#11) a couple of times already.
Still, there are some radio files (AMSS?) that eventually could help. I'm trying to find those but the LG's seems harder to find.
Thank you all.

I've just read your post . I have exactly the same problem. I have also bought my OB with a hope that I could fix it . Did you found a solution for your problem ?
Thanks in advance.

maybe your phone has lock on mobile network?

same problem here :/
its all after my phone has been rooted!
it was via blackjack

Maybe some of you are wrong ! Maybe it`s software related.
If you root it with blackjack this dont`t kill or get your hardware malfunctioned because it only trick your firmware to get privileges. Hardware is not the answer.
Maybe you all must try the unbrick thread from Optimus Black Android Development with the option of Erase CP and flash .bin and .fls files on your OB.
It happened to me too when i was flashed CM nighly`s. The cure was to to flash nova rom and nova kernel v10c and look now my phone work very well whithout any SIM problems.

I have tried to unbrick my phone this way but I cant activate "Erase entire CP".
Windows anabler "on" doesn't help too. I will try to install nova kernel v10c as you recommend without Erasing cp. Maybe it will help.

I dont think there is Simlock on this phone. When I want to enter unlockcode it shows me "your phone is not personalized". So it seems there is no Simlock.

Exactly ! I think if you want that Erase Entire CP you must go in hidden menu of OB and tick CP USB instead of ...

scamex, thanks to your advices I have solved my problem. As you said I got to the hidden menu , then AP CP USB Switching and CP USB . After these steps I could check "Erase entire CP" in Smartflashtool . I have flashed my phone with v10c rom using .bin and .fls files and now I have the signal and my SIM is recognized again. Thanks so much again .

So now check your IMEI via *#06# and this one under your battery

Phone does not connect to Network (started after being stuck at samsung logo)

Hi everyone,
I rooted my note and was using Jon ROM V3 for the last 3 months. Never had any malicious apps and my phone was working as usual.
Yesterday I took my phone and see that it is stuck at Samsung logo (an hour ago it was working fine). Tried reset and re-flashed ROM but no luck.
Later through download mode i flashed Official Indian Firmware(I live in India). Now I by passed the logo screen and the phone shows full signal bars but not able to connect to carrier network.
(tried all basic work out like removing battery/sim and re-inserting to phone and boot up)
I pressed power key and it did not show the power menu , it directly switched off mobile.
I rooted again with Philz kernel and flashed JON ROM. Still i see that my phone is not able to connect to any network. Also I observe that even here on this ROM when i press power key it directly turns off.
This is weird. I thought my IMEI was wiped off but im lucky to see that its still there.
I need your help. Im without my phone for the last 2 days now.
-
Jonathan

Note - I find that my IMEI number has been changed (to some generic IMEI 004999010640000) after i flashed the official firmware !!!! that's why it is not connecting to any network.
Someone please help me.

How did you flash the official firmware?
was it a tar file or a zip? I mean did you use odin?

It was a tar file The official Indian firmware I got from sammobile

either a glitch or you selected by accident clear efs.
anyways without efs backup hard to recover emei.
Do you get the simcard enter pinscreen on boot? If you dont then its not imei, if you do then you need someone like cvxcvx, search to fix it. That or Samsung

No I do not enter pin for simcard. I see my imei has been changed to 004999010640000. I tired fixing one problem and got onto another.
I guess there is no way other than sending my device to Samsung !
Anyways I appreciate your help. Thanks

You have a so called "developer IMEI". If you didn't safe your EFS then there is no real chance to restore it yourself.
There is a member (cxlcxl) who has hardware and can restore the original IMEI remotely.
But you still can use your device. Try to change the Sim Pin in the settings: you can use the same Pin for old and new (this is easier for me because sometimes I forget the new number).
After this the network connection should come back.
My workaround in my Pristine Custom Rom: one different jar-file that doesn't have the checks on startup from my old XXLSC dump. With this it works completely normal: Sim and Pin are always recognized from startup. I'm using this for many months now.

[Q] No ''SIM unlock code'' prompt

Hello guys. I have a bit of a problem. I have bought a Droid 3 , blocked on Verizon and it doesn't ask me for the unlock code. I searched everywhere and did not come with an answer. I have to mention that I am from Europe and the person that had the phone before, tried to put the codes more than one times and that may be the cause. Can this be fixed? Thx.

Hi, did you try to leave the phone on for about 2 hours? It should ask you to insert the unlock code at a certain point, even if the maxumim number of tries has been reached.
Is it XT862 model?

Yes i tried, i left it for an entire night. Yes it is the XT862 model.

If you dial #073887* the sim unlock code prompt should appear.
Please try that, if you haven't done it yet.

Done that. Nothing happened. I dialed the code into the dialer application. Have i done something wrong? Thank for the help , by the way.

You're welcome.
I don't think you did something wrong, you just have to type that code in the dialer and when you insert the last '*' symbol the prompt should appear. I tried it on my Milestone 2 (that has never been locked) and it works.
Are you running the stock GB rom or there is a custom one installed?
Did you try with another SIM card?

i am running the stock verizon GB.

This is a known issue in around a third of the droid 3s. For some reason they can't unlock properly. It's possible that you have one of these...

[Q] No calling, no texting, everything else works

Hi everyone!
I bought recently a new galaxy s advanced and for some weird reason i can't make calls, can't text and can't receive anything. But i can unlock my sim without any problem and i can use mobile internet.
I had first the original gingerbread rom (i9070XXLK2), rupgraded it to 4.1.2 jelly bean(i9070XXLQE), rooted it, upgraded the kernel to this one: http://forum.xda-developers.com/showthread.php?t=2140597 and after that tried a cyanogen rom(this one => http://forum.xda-developers.com/showthread.php?t=2497660 ), went after the cyanogen back to the 4.1.2 but nothing works.
atm it is running original 4.1.2 rooted and cwm.
I also tried galaxSim but it doesn't support the galaxy s advanced, also the *#simlock# thing does not work. I am not sure there is a simlock on the phone because mobile internet works.
If you need more info just ask! Not really sure what information you need to know.
I have no idea what to do now, i hope some1 can help me.

You must do Factory reset when you change ROM. Do it now.
Do you have I9070 or I9070P? On CM you do not have network unless you change tee folder if your phone is I9070P.

I have factory resetted it 3 or 4 times (after every rom flash).
It's an I9070, not the P one.
If some1 tries to call me they hear an automated message tape thing that says my number is blocked and i need to call my provider.
I did call my provider and there is nothing blocking my number or the phone.
When i put my sim in another phone everything works fine so the issue must be in the phone itself.
Thanks for trying to help :highfive:

I tried 3 different SIM's but all from the same provider, i am going to visit a friend tomorrow to lend his SIM (he has another provider). I wiped dalvik cache every time i factory resetted it (after every rom flash)
Is it possible there is a piece of hardware in the phone blocking the calls and the messages?
Found out something new, if i do phone (the app) => call settings => additional settings, i get a message saying "network or sim card error".
I am searching for an hour now for a fix but i can't find anything. I will keep searching for another couple of hours, i really want to fix this.

I don't know, as far i can see there is no sign of a provider/region lock. During boot no logo from a provider, sim can be unlocked when it asks for my PIN.
I tried to figure out if there is a simlock with *#SIMLOCK# but the code does not work. Any idea how i can see if there is a sim-lock?

I bought it from an auction, a phone shop went bust and they sold thousands of phones. They had over 20 shops and they were not promoting a provider.
it was brand new in a sealed box and as far as i know i don't have warranty.
Is there a place to check if there is still a warranty on the phone?
EDIT: just checked and i have still warranry (produced at oktober 2012) but the problem i have now is, i flashed it a couple of times, isn't my warranty ruined now?

I am not sure how is it in your country about that. You can go to some service center to see if the phone is locked to some carrier.

I just tried to check the binary counter, but as far as i can see it didn't move during the flashes and looks original
When i go in download mode i get this:
Odin mode
Product name: GT-I9070
Custom binary download: no
current binary: samsung official
I think this means it got still warranty?
If it is, i'm going to put back jelly bean on it and try to send it back to samsung, is there a chance they will fix it and won't find out i messed with it?

Sad news, the phone is back from RMA and there is a simlock on it, but the problem is i can't find a method to remove it 4 free (don't want to pay even more for the damn thing). I am going to a shop from the original carrier over a couple of days(i know which carrier simlocked the crap out of it and they have shops not really far from here) but i am not sure they unlock it for free, and tbh the people that work there probably have no clue how to do it, so i don't have a lot of hope for that so i want to try it first myself if that's possible, but i tried already a couple of things and none of them works. Anyone an idea how i can remove it?

I was afraid of that, thanks to confirm. Went to the carrier which locked the phone and they said it is illegal to unlock it, which isn't true of course (checked it everywhere and it is legal) I will find a way to fix it with the carrier, thanks for the help.

SM-G800F no network, changed IMEI

Hello XDAs,
After reading that Forum with much enthusiasm for a few...well...years, i got my first question.
I hope you can help me with a big problem on my g800f: I can´t register in network.
When I search for network it pops up a few results, but if choose one to register, it says "Can´t register. Try again later."
I did a few hours of research and found out it might have something to do with my IMEI (Note: till that day i did nothing to my phone, except cf-autoroot. But never faced any problems!).
So I checked my IMEI and it wasnt the original, it was changed to 350695200123951. So I googled a bit and realised it might have something to do with the efs-partition. Googled for solutions.
Found out it might help to flash a Stock-Rom, one with three parts, via odin so i did it. Everything worked fine, but my IMEI still was the different one.
I was a bit irritated so i searched for that IMEI. And there are a few threads (some in russian and arabian), also owners of a g800f, which also reported this problem: They did nothing, but sudddenly the IMEI changed to this number. One author tells he received a myserious call from the ukraine after this happened. He didnt answer it. I am quite sure i also received that call- I didnt answer it either.
So i googled even mre: "How to restore a damaged efs-partition, without backup?" I came to one very outdated guide which wanted me to delete the efs (after saving it on externalSD) and do a few mysetrious actions...
Well, i just realised i cant fully delete the efs, its not possible and i also cant apply my backup from external sd. Anyone knowing a solution for this?
But, the most important, how can i bring my g800f back into mobile network?
Or just: How can i get away from that cursed IMEI?
Any Ideas?
P.S. If you got any questions regarding technical details of my phone(CSC, AP, Kernel, Modems), just ask. I´ll answer.
P.P.S I´m excusing for that horrible english. I googled the entire night and i´m german.

I´ve just seen this problem being reported i a different thread. Guess the problem will be discussed there?

Hi All,
Did any one actually get a fix for this issue as I have exactly the same problem, my SM-G800F IMEI now also shows as - IMEI 350695200123951-01 which is for a blacklisted NOKIA 6310. If anyone can supply an absolute beginners guide for me as to how I can get my original Imei back that would be fantastic.
I am just a user of an android phone and have zilch experience of tinkering with them.
I have seen reference to things like Odin and flashing firmware and am quite happy to give it a go myself and learn
I will post this on a few other threads that list the same issue as I am desperate to get this fixed now as is a waste of a perfectly good phone !!
Cheers.

SM-G800F, can't register in network
Hello,
I have exactly the same problem. Since some month I got the message "can´t register in network". After checking all, I found that my SM-G800F IMEI has changed to a NOKIA 6300 IMEI.
If anyone knows a fix for this issue (set back to the orignal IMEI) , it would be great. All apps which I could find didn't work (XPOSED IMEI Changer Pro , Mobile Uncle Tools App, MTK Technikmodus... ), are not supporting S5mini.
I don't have a backup of the original system EFS file.
Would be great when one could help.
Regards
Chris

@S5miniChris somewhere in XDA I read that restoring the original stock (multiple part) firmware might or did help.
Gotta do it in Odin (recommended to use an older version like 3.09).

Thanks for your reply.
I have installed the original stock firmware. But it did not change the IMEI. Available for my model is only the single file " G800FXXU1CRG3_G800FDBT1CRE1_G800FXXU1CRG3_HOME.tar.md5"
Multible file firmware I couldn't find.
A manual modification of the IMEI should be possible with " Best smart Tolls " e.g. : BSTPRO 4.03 . But for the software a dongle is requiered. To purchase this is for one time use too expensive for me

Where from did you get the stock?
Samfirm_reborn tool already tried?
https://github.com/ivanmeler/SamFirm_Reborn/releases
Checking "binary nature" or "factory mode" downloads a multiple part rom.
Edit:
Checked tool and it's working.

I flashed now also with " binary nature " firmware downloaded with SamFim. The IMEI is still the same, it hasn't changed to the orginal IMEI.
I really can't believe that a firmware update will flash the E2PROM where the IMEI is stored. Therfor the orginal IMEI must be stocked some where
in the phone and by flashing transfered to the E2PROM.
