No sim card problem - XPERIA X8 Q&A, Help & Troubleshooting

Hi i did a search for the problem but none of the other threads with this title matched my problem.
I'm hoping someone can help i rooted and unlocked the bootloader on my x8 and put on ginger DX about 2 months ago and it's been working great.
just for info I didn't flash any custom kernel
So to my problem i tried to send a text message earlier tonight and i wouldn't send. my phone appeared to have no signal. I moved about in the house trying to get a signal no joy. So i rebooted my phone when it came back on it said there was no sim card!
Thinking something had gone wrong with the rom I tried a full wipe through xrecovery to no avail so i then did a repair with PCC.
However my phone still says No sim card
anyone know of any other steps i can take to fix my phone?
if it's beyond me fixing it I'm with O2 and have insurance will they be able to tell that i rooted and unlocked the bootloader and is that likely to invalidate my insurance??
Thanks in advance

going back to the previous reply wouldn't doing a repair with PCC relock my bootloader?

FIX
I had the same problem. did you use this guide HERE?
If not do the whole guide following his instructions.
or
If you did go to the bottom of the first post and look at common issues. One of them is sim is not recognised. All you have to do is use the other unlock tool.
You will have it fixed in no time!
Please thank me if you appreciate my effort to try and fix this problem.

I wasn't trying to re unlock my bootloader i just wanted my sim to be recognised, but if i reunlock it is it likely to be recognised?
I didn't use this guide when i originally unlocked my bootloader i used x8toolbox

Have you tried inserting the sim to other fone and see if it works? or try using different sim and see if the fone recognize it.
Im guessing your sim card was damage.

Just tried that just before i turned the computer on and i was just thinking the same thing then i saw your reply
now just need to unroot the phone and lock the bootloader before i ring O2
Thanks for everyone's replies and i'll try to put my threads in the right forum next time

You did not unlock the bootloader properly. There was a bug. if sim is working before and not working afterward. Baddaman54 is right. you need to follow the guide and troubleshooters notes. Even though this has been solved I will make this post so that if someone comes here with the same problem they can see all solutions.

I didn't follow that guide at all, as posted earlier i used x8toolbox and i ran the s1 tool which seemed to indicate it was unlocked fine
But i did it about 2 months ago. The phone and sim's been ok all this time running GingerDX with stock kernel.
it appears the sim is damaged not sure how it happened though.

a) Check the manufacturing date (sticker below the battery) and then search this Q&A board to make sure your phone isn't too new - you'll find several threads with a warning about phones out of 11W29 and onwards being candidates for a hard brick due to hardware changes. You can NOT revive the phone yourself - you need to send it in for repair and they will most likely change the motherboard! You've been warned to think at least twice!
b) There are several people who unlocked the boot loader while having GingerDX installed through the manual method. Safest way, or course, is to flash back to Stock and unlock from there.

Unlockin bootloader with date above 11W29???
Hey guys I tried unlocking the bootloader on my x8 the manufacturing date was 11W39 so as you can guess I got THE Hardest Brick. Then i took the phone to my mobile operator, told them that it was switched off when i plugged it for charging and that when it said battery full it would not start. And it worked!!! They replaced my motherboard for free I guess the warranty was still valid apparently xD. So, I came home installed GingerDX right away but i really want to port ICS 3.0 on my x8 and i would really appreciate if someone had any ideas how to unlock the bootloader on a motherboard 12W and something above. I've read that a couple of guys managed to do it, so anyone pls help before i go and cash out 400 euros on the HTC One X.
Thanks.

Well, if with 11w39 you got hard brick, you will also hard brick your phone again because the motherboard is even newer. It's better to not try it. You have very very few chances to unlock bootloader with 12w and above!

Successfully UNLOCKED Xperia X8 11W35 just hour ago!
I was scared with all disccussions here but I wanted to try, however it could finish.
I had followed this guide: http://forum.xda-developers.com/showthread.php?t=1254225
I am not encourageing anyone to do so, but it is good to know that 11W29 is not the limit, maybe it is 11W35?
Or maybe it has something with guidance? For me, guides by SpiderX were succsessfull.

Rebooting problem with SIM card.

When I insert a SIM card into my phone, it always reboots after it finds signal. So I could be in airplane mode, but when I disable it, the phone reboots just after it finds signal! This first happened on MiniCM7, then I tried GinderDX, but still the same! I have unlocked bootloader, Alfs v09a and GingerDX v028, if that matters...
PLEASE HELP ME

I don't think that would help, because it worked perfectly even with custom kernel. I used the same ROM and kernel all the time, then suddently the SIM card rebooting problem appeared. The problem was there too with Alfs 08!
No one can help me?
Maybe its a problem with your sim card chip? It may have been corrupted or damaged. Go to a communications store and check..

My SIM card is not damaged, it's the phones fault. What should I do?
Try downgrading to 2.1 all stock softwares will be restored then you can know wether it is hardware or software problem .. if it isn't solved then can be hardware problem with sim or sim slot...

How are you sure the Sim isn't damaged.. It may well work in another phone, maybe just that the x8 is highlighting that there is an issue?
Your provider will supply you another sim for free so it's easy to get that verified..
Try another sim in your phone (x8) and you'll soon find out..

insert your sim then press the power button
wait until bootanimation appears nd connect your charger to x8 when bootanimation is running.
your phone will boot safely but remember when ever you plug out your charger it will reboot again.

Same issue here. Anyone?
I don't think this is caused by my SIM card. It happens with other SIM cards too and my SIM works fine on another phone.
It does not seem to be software either because the problem still happening after flashing the stock rom with SE PC Companion.
I even bought another Xperia with the screen damaged and tried to replace the full main board but the problem still happening. After this, I tried to replace only the screen on the other phone to see if it would work, but it didn't!
Now I don't know if I bought a damaged phone with the same problem as mine or if this problem is caused by my LCD screen (that is the only part that the phones shared).
Mine is E15a with unlocked bootloader. I flashed SEMC Debrand Engine around a week before the problem happens.
The other X8 is also E15a, but it does not have unlocked bootloader (capital R) and arrived with stock ROM and full reset, so I do not know it it was "custom flashed" before.
F** weird problem!

Unlocking bootloader is restoring the sim-lock state. I'm not too sure about that. But I hope your phone is locked back :/

Yes, my X8's bootloader is unlocked. I've bought a X8 without LCD to replace my main board and this new X8'bootloader is not unlocked.
And to give you some update, I've just found out what was the problem!
The problem was with the battery. Since I replaced it, I have had NO PROBLEM AT ALL anymore!
When I wrote the last post, I forgot that the battery was also the same in both phones (just like the screen that is from my first X8).
I will try to follow this tutorial to see if can make my phone work with the old battery, but I am not very confident that it will work.
Anyway, I'll let you know if I have some news...

P970 can't use any SIM cards

My Optimus Black was working fine for about 3 months. Not sure what happened, but it started showing no network/signal. It's a completely unlocked phone. I tried a friend's SIM card and the first time it wouldn't work, but I tried again a few days later and it worked but had a pretty bad signal. Now it won't work no matter how many times I try. I even bought a new SIM card/number (I live in Asia) and it won't work.
I had Android 2.3 and thought maybe something got corrupted, so I wiped and reinstalled, but same problem. I wiped again and installed Mokee OS, and same issue. (By the way, after using Android 2.3, switching to Mokee is so much nicer, although it's in beta and still has some bugs.)
The 6 gold SIM connectors look fine. I used a SIM app and it recognizes the SIM card and its carrier, so I think the card is being read OK.
I live on a small island, so sending the phone back to LG or taking it back to where I bought it (Bangkok) would be a huge hassle. Does anybody have any ideas on things to try to fix this? I'd really appreciate the help.
Can you return to stock rom (rooted or not, as you want) and then tell me if you see something write in LG lockscreen (I'm thinking about LG Security Error) ?

The first time i wiped the phone i went back to Android 2.3, but all that the lock screen said was "No service". Usually it says "DTAC" when I have service. Is that what you mean?

No if the SIM card isn't used that phrase is normal. I got a problem like you but it was written "LG Security Error" and I had to use Smartflash tool erasing cp and then recover my imei. But it doesn't seems that you have the same problem. "/

I flashed the new rom and erased the CP data. still no phone service but i haven't reset the IMEI yet. having trouble with that step. i'm not sure if this is going to work though, my problem seems different. my phone can see my SIM card, but i just don't have any phone service with any SIM card. the sim cards work fine in other phones.
try a sim without pin code

i don't think my SIM has a pin code? I'm not sure though? There's only one type of SIM you can get here in Thailand. You buy the SIM from a phone shop or 7-11 and add credits to it. I've never seen any other type of SIM card.
Yep, I used smartflashtool and erased the entire CP (had to enable with Windows Enabler). Now there is no IMEI and still "No service".
Retry or by changing baseband now...there was a tutorial in optimus3D threads i think
Or in this one itself
Change the baseband

[Q] SIM stopped working in my LG Optimus 4X HD

I'm new to this.
A totally random event. I restarted my phone one evening last week and it show no sim. Using the LG support tool I had multiple failed attempts to update the software. Then as sudden a the sim registration had disappeared it came back to life. All fine until again the phone just stopped registering the sim.
Phone is secondhand. And I have tried numerous times removing, cleaning and replacing the SIM. Tried another active SIM on the same network with no luck.
I've never had a 'bricked' phone so don't know what to expect but I imagine the phone wouldn't even boot up!
I have now rooted the phone and installed CWM recovery, still no joy and have in desperation performed a hard reset. Nada!
Software is V10h. I read something about EFS folder to backup but all I could find is a text file. The IMEI is not registering on the phone. It could be a very simple answer but currently I'm stumped. I have requested a replacement SIM but have little hope this will resolve the issue.
I hope someone has an answer...

re-flash 10h or 20a kdz. look for various tutorials on the forum. (btw, your phone isnt registring on network cuz your imei isnt being read, probably due to failed upgrade process
(or some other bug). it should be fixable though)
also, replacement sim wont help. its your cell phone that's faulty, either hardware or software, not the SIM itself
also, i'm not sure how it goes if your IMEI is blacklisted by your cell phone company - is it possible the phone was stolen? perhaps the original owner reported it stolen to his carrier and they blocked the IMEI?

If the IMEI is blacklisted, the phone will still show it correctly in the settings and the carrier will just block based on this. This is why changing an IMEI is illegal in most countries and why discussions on how to change it aren't allowed on XDA as it can get the site in serious trouble.

check if ur gapps are fine. reinstall all gapps. maybe u deleted some app that u shouldnt. happened to me too 2 weeks ago and i had no sim so signal , i couldnt see my imei, etc. if that doesnt help , then reinstall ur rom or install a custom one. I mean maybe u must be sure to check if u deleted some system app that u shouldnt. Since u have double checked with other sim , if its not from an app , then the above thread is right, the owner could have reported the phone stolen

Okay, strange happenings with this phone. I've not hd the opportunity to re-flash as suggested but by the by I put my SIM back in and it worked fine. IMEI registered in the phone settings and all was as it should be. Until again first the signal disappeared and when I restarted the SIM did not register. Has anyone experienced this before?

There have been some problems with this, but normally due the the RIL on CyanogenMod-based ROMs. I would suggest that you find the time to either reflash v10h or upgrade to v20A/B/C (as appropriate for your region) and see if that fixes it for you.
you still havent mentioned anything about gapps. this means you checked and you are sure that they are fine ??
So I have tried flashing software V20A using the LG software updater and now all I get is the phone booting into 'S/W Upgrade please wait while upgrading'
I can get into any other screen, despite pressing all combination of buttons together.
I have attempted reflashing back to V10H and try and get it back to how I had the phone. No luck there
And also tried again with V20A. No joy.
Is there anything else I could try?

I have always found this thread [TUTORIAL]Update firmware through flashing the kdz files( With Picture )Step by Step works perfectly every time.
Got the same problem here, running cm for a month with no probs, restarted phone and sim not recognized. Installed a backup of the original rom and everything ok. Reflashed kdz's and did a fresh install of cm and still no sim. Am now on Zaiben which is ok but takes about 15 mins to recognize sim?

hi, sorry but no, i think it was probably hardware related as it would no longer allow me to flash kdz's.
good luck.

[Q] SIM-card(s) not readable

I've got a more or less big problem. My Xperia SP cannot recognize, that my SIM-card is inserted. If I turn it on it doesn't ask for the PIN and furthermore I can't receive or send SMS's, I can't receive calls or call somebody and I haven't got mobile data. I tried to insert my SIM-card in another sony phone and it didn't work. I also put another working SIM-card in my phone and it also couldn't recognize it. I think (I'm actually sure) it's caused by the non-functional phone apk, but maybe also the SIM-card is broken.
What shall I do? I have a TWRP backup, but I'm not 100% sure, whether it is from before or after. What is a less- or non-risky possibility to replace the phone.apkor is there a better method to repair the phone?
edit: I found out, if my phone is turned on and I remove the SIM-card, it realizes it, and reboots.
Please help me!

Sorry, but why is my post ticked with a hook??? The problem isn't solved yet!
Get a new sim card.. This will fix most simcard issues

First of All thanks for your reply. But I already took another SIM-card (which on Xperia L works fine) and put it into my device but there were the same problems. Yesterday I downloaded the SemcPhone.apk file, pushed it to /system/app and changed permissions to rw-r--r-- and rebooted. Then it asked for the PIN but after unlocking I got a bunch of Force closes and they didn't stop.. Even after rebooting again I had the problem, so I deleted the apk file again. But it's now the same like I described there above :/
Reflash ROM.. You have phone.apk problems aswell so this should fix it
Okay.. And the stock ROM, is this the "Deodexed stock ROM" (777MB) from android development or the "normal" stock ROM (odexed) (12.0.A.2.245) also from android development section?
No, to prevent any issues just open Sony Update Service (can be downloaded from the Sony website) and "restore" your phone..
So go back to full stock
Okay cool thank you I'll try it

The last version of Sony Update Service misses the XSP.
I have contacted Sony Mobile to point this out. Untill we recieve a new update you need to use the PC Companion to restore your phone or you need to use Flashtool

Okay, then I'll do that
:/
I tried it with PC Companion but when it had to start repairing and it booted the phone into flashmode (I think so, because the LED was green) and then PC Companion said: "The phone contains modified software, which cannot be updated" and below "Error 2003" ..
I tried it 2 times and both the same :/
My phone has unlocked bootloader, is rooted, and has the DoomKernel, no custom rom.

Well that is unfortunate. You need to relock bootloader and reflash with flashtool.
You cannot use Sony software with unlocked bootloader

Oh! That's actually bad. But then I first have to flash back the stock kernel, then relock bootloader, repair with PC Companion and eventually unlock Bootloader again if necessary for me, right? Just for being sure.
Yes correct you need stock kernel then lock bootloader,then re flash/repair phone

Ok good. Now the last question: from where can I get the right stock kernel? I found a post from DoomLoRD, where he wrote, that you have to flash stock kernel.sin and no FTF kernel but I couldn't find a stock kernel.sin and in another post from alivanov79, alivanov79 posted a link to an FTF kernel. So Do you know which one is the right one?

Hello! I hope you're still alive!
I am facing the same problem, but before I start doing stuff, may I know if your problem has been solved?
My Xperia SP as well on occassion doesn't detected sim card. Sometimes when I need to make phone calls the most, it starts to do it. I am planning to send it for warranty, as I am having another 20 days before the warranty expires.
Surprisingly, many Sony Xperia models users have experience of having a phone that doesn't read SIM cards. Google reveals it all.

Hey,
yeah, I'm still alive
So, the thing is, my problem there had been caused by myself, fiddling around with some root stuff, so it hadn't been my phone's fault.
But what I did is I just flashed another ROM because I didn't see another solution and it really drove me crazy not being able to use the SIM card related functions.
Well, keeping your post in mind I don't think you'd like to flash another ROM (I probably shouldn't have done that, too).
So if you didn't already try to repair your phone with PC Companion, that'd be the first thing, I'd do in your case.
Otherwise I'd send it for warranty as you considered it already.
Yeah, my sister's Xperia L also has that problem and that's really unfortunate.
So I hope, my "advide" could help at least a bit although there may not be plenty of hints, but yeah.
If I shocked you with that essay I'm sorry, too

Lol I don't think ROM flashing is the root problem, as I have been using CM11 for a month (and maybe more). The problem starts appearing lately..
I will flash stock ROM and relock bootloader and then reflash stock via PCC to see if it will fix the problem
Anyway thanks for the reply!
No, that's not even something to be called "essay"....
