HELP! x10 keeps on rebooting/restarting with a sim card in!

Hello guys, I am having a problem with my unbranded x10i bought in UK (I am currently using it here in the philippines with a local sim card) . After I did an OTA two days ago, it just keeps on restarting/booting! I have tried the "repair" option twice in the PC Companion software but still no luck.
What's strange though is that when I tried switching the phone on WITHOUT a sim card in, it booted up with no problem (and I checked the build number, it says R2BA020 which probably means the OTA update was a success). I put the sim card back in and the problem came back, it kept on restarting.
What seems to be wrong? Any suggestions on fixing it? I would really appreciate your help guys. Thanks!
Update: I successfully rooted my phone hoping that rooting would solve my issue, but unfortunately it still keeps on rebooting/restarting whenever i put ANY sim card in.

Have you tried using another SIM-card?

yes. I have used different sim cards...

Try flashing back the original firmware.. and make sure the sim card is inside the x10 while doing it. Worth a try..

I have the same problem too and I have just updated my phone to R2BA024 and the firmware version is still 1.6. I have hard-reset so many times and reinstall some many times. The problem still there. I have contact Sony Ericsson customer service and bought my phone to fix. Got it back, problem hasnt been solved. I have waited for 3 weeks for a reply from them and end-up they said they do not have any new phone or spare-parts to fix my phone. Until then, I have contacted them almost 10 times and still no one has the right answer and just keep asking me to wait. They dun even have an exact date when the parts will arrive. I am very piss off now and I dunno what I should do next.

Its the same problem here with me too. Bought the phone from a friend about 3 days ago. was going all good when it just started to keep booting itself. While the sim is inside, it'll restart just as it finishes booting. Without the sim, its fine. I have tried other sim cards too, and format/reset my phone many times but it just isnt working for me anymore. HELPPPP!!!

Is it 32K sim or 64K???

hi techguru, can u tel me wot the diff is between the 32k and 64k sim ? many thanks

ISSUE SOLVED here.
BTW : my sim is 64k.
anyways, i found out that the problem was because of the faulty battery. what i guess is that the voltage couldnt get to the requirements of the phone, and everytime the sim radio (whatever its called) switched on, the phone just turned off.
I reinstalled/repaired my phone many times, GOT the exclamation mark of death one time also, but the phone just didnt turn on.
Later i noticed that the phone would just turn on itself when i attach the phone to the charger, otherwise it wouldnt turn ON. So what i did was just change the battery, and walla, the phone is ALIVE again.
Sim is working, phone is working.
BUT i see some signal losses from time to time, otherwise the phone is good enuff.
FOR me , the change of battery did the trick, I hope it works for u guyz aswell.
Cheers ...

hmmm. sounds interesting. I might try changing my battery. btw, i have tried using both 64 and 32K sim cards but the phone keeps restarting with any of the sim cards in. without both the sim cards, the phone works fine. how much does an x10 battery cost?

here, i get the cheap chinese battery. it isnt expensive, but its working great. almost better than my previous battery.
cost me around 2.5$.
but.. i am still getting lots of SIGNAL DROPS. i dont know why it is happeneing. I tried swapping the battery with the original battery of another X10, but no change. Signal loss is not a battery issue then.
Any idea what it could be ??

Signal loss?
Maybe a weak signal, or radio related?

or maybe its because i updates it to R026 is causing the signal loss issue ??

@techguru
I am also using airtel, but with a 64kb sim.
In my case it does not start.
It start if with no battery or with a 128kb sim of TIM.
I tried to recharge the firmware but nothing seemed to change.
I know that someone solved the problem swithcing off the phone in airplane mode, but this is not the case for me.
I also noticed that in some cases the led is green and is slowly blinking.
I am ready to change the battery if this helps, but I am not sure. Even if I put it under charge it does not switch on and the battery seems not to charge
As I bought the phone only since one day I wonder if they will change it.

SIM card issue... any advice?

I'm not sure if this is a common issue or just an issue with my sim card.
Looks like the sim card just stopped working this morning. I can't make/receive any calls or texts and the lock screen says "Please insert SIM card and restart".
I've restarted about 3 times now and have tried removing and reinserting the sim card, with no luck.
I figure I'll need to take it into a T-Mobile shop to get a new sim card, but my Vibrant has been rooted and has a the Obsidian Froyo rom installed.
Should I just plug the SIM into my old blackberry and take it in that way for replacement?
Or is this some known issue that can be easily fixed?

I have had this happen to me twice. Once, the SIM went bad (it happens).
I called TMO told them that it's not working & they said they'd get me a new SIM. I had the option of going to an authorized TMO store or getting it mailed to me. I went to a store, they installed & it off I went.
The other time, I took some rubbing alcohol and a QTip to it & cleaned it up, let it dry, put it back in & it's been working for a little over a week now
So, I'd try giving it a cleaning first and if that doesn't work, give TMO a call.
If they don't know that you have the Vibrant and think you still have a BB, then yeah, I'd put it back in that rather than bringing in the Vibrant if you have to go to the store. It's just easier when the person helping you isn't trying to force you to change your plan at the same time.
Question: The phone won't let you do anything without a SIM card? If that's true, that's just another reason to be glad I SIM unlocked my phone....that would get annoying!

Old Tmobile sim cards actually have a certain amount of times they can connect to the network tower. If you use airplane mode a lot it you may reach this point quickly.
And some sims cards just go bad. Which I think is the case with yours tjhart85. Take the phone and card to Tmobile. Tmobile will change the sim card for free.

Yup, turned out the sim card just went bad. Called up T-Mobile customer service, they put a not on my acount, and went into my local T-Mobile store and got a new sim card. Phones working great now. They didn't even ask for the old one and didn't have to look at my phone.
Thanks guys!

Nexus 4 SIM not being detected

Hi,
I just bought a second hand N4 to try out Android (WP8 user here).
The guy I purchased off showed me his SIM was working in it fine but since taking it home I haven't been able to get any SIMS to work in there. I have tried quite a few, all of which work in other phones.
I've done a factory reset multiple times, rebooted the phone multiple times and even tried starting in recovery mode. Nothing I do seems to be able to get any SIMS working.
Really frustrating experience as otherwise the phone works fine on wifi. Really hope someone can help me as otherwise I just spent $180 on a dud!

i'd try stopping at a tmobile store and replacing the sim card....you shouldn't get charged.

Thanks but I already got a new sim today with no avail. I've tried 3 different sims now, and none of them work in my phone. But all work in other phones.
I'm in Australia too btw

Make sure your phone is shut down before inserting one.

Is this really likely to work? I'm hesitant to try this as I'm new to Android and have no idea how to do this...and have heard many horror stories of flashing and rooting going wrong.

Evening/Morning Matey. Just out of curiosity. I take it your phone is confirmed as being a sim free,carrier unlocked version?
Or at least your using the Same provider as the guy you bought from.

I've had this problem too. Try to use an adhesive tape on the side of sim card to prevent a short circuit with the metalic tray of sim card.
It worked for me.

No Sim Card

Hi everyone,
Yesterday my phone stoped to recognise the sim-card.
At first i got a message with sim-card problem and the phone need to be restarted.
After that sim worked a day and now i cant use any sim in this phone. I tried it with 4 cards.
I've tried new roms , and paper on sim-card reader. Still "no sim card"!
Is it possible to repair it or is it Motherboard problem?
Thanks.

Have it checked in a authorised Samsung Service Centre mate. I had that problem twice in one day few days back, but since then its running fine! I was really scared, thought I would have to visit SC, but it went away on its own! I don't think Motherboard needs to be changed, only the SIM slot if its damaged.

Thanks for your answer. My phone doesn't recognise any card now. Since 2 days. I don't think it can go away on its own

Got the same problem. Probably your sim card slot got some loose like mine. I put a little piece of paper into it on the back of sim card. It caused that my sim card was inserted tighter into slot and it is working again.
It occured that it was the sim card problem. I had it again but it was strange because it worked on my sony xperia sp. But my note 4 didnt see it. I checked other sim card and it work flawless

[SOLVED ]Nexus 6P - No service message

Hi all!
I've bought a Nexus 6P in september 2016, worked fine in every part until yesterday: my phone stopped showing signal strenght and says "No service" in the upper left corner of the screen.
I was on a custom ROM (Pure Nexus) but:
- Restoring factory images didn't help
- Restoring the oldest Marshmallow factory image didn't help either
- Erasing cache didn't help
- Switching to 2G and 4G didn't help
- I did a network settings reset, nothing changed
- I've switched to a new SIM card, nothing happened (old SIM card worked well on other phones, like this new one)
- I've never touched EFS partition but my IMEI is still there, so i don't think it's a network problem
So... Any ideas?

Oh man... I was hoping it was just me. This has happened to me too within the past few days, twice.
After waiting a few minutes it came back. It *May* be they are doing tower work. That's what I'm hoping.
I am on Verizon Wireless on the 3.79 radio if that helps add info to the pile. What radio are you on?

I'm on the same radio, latest radio in latest 7.1.1 release, january security patch, as i said before, installing the oldest Marshmallow release (so the first radio released by Google) didn't change anything!
My provider is Vodafone IT, I don't think they are doing some tower work, because everything works fine on other phones and the same SIM card in!

Good day,
Got same issue few days ago, after phone restarted due to installing January security patch. Phone was not rooted on stock firmware 7.1.1 with locked bootloader.
Cellular network don't work at all, if try to find network manually it return: Error while searching network.
In *#*#4636#*#* all switches in OFF position and cannot switch on. IMEI available.
Also when try to make a call(without network of course) it return: Turn off airplane mode to make a call. Of course it not turned on.
I try flash vendor, bootloader, baseband/radio(3.72, 3.78) previous stock firmware 6.0 and 7.0.
When flash cyanogenmod 14.1, SIM card was not detected.
Carrier Elisa (Estonia), bought in November.
Any ideas?

If you're not on Verizon, I would just switch back to 3.78 radio. Flash it manually. Don't see how that wont fix your issue

Hi mate, a friend of mine have a Nexus 6P, we are on the same carrier and the same 3.79 radio, everything works fine on his phone!
So my problem is not radio realated!
Radio 3.79 is also good for other carriers over Verizon.

Hardware problem with Huawei. The gold contacts on your SIM card are not making contact as they should. Likely a problem with the SIM tray.
Eject SIM card and put some scotch (cello) tape over the card to hold it in the plastic tray. You may need two strips (I did.) Now reinsert the SIM tray. All should be well now with your cellular connection.
Added thickness of the tape holds the SIM contacts to the connectors inside the phone tighter when the tray is closed and the problem is solved.
I did this about three months ago when I started having this problem and have been fine since.

Yeah, me too, I've bought my Nexus 6P trough eBay and was a private seller, it seems that private sellers are not required to provide a warranty...

If you buy from EBay your only warranty option is Square Trade but if your phone was bad when you got it you can file a buyer protection claim

I know you tried an old SIM, but have you been up to Vodafone to get a new replacement SIM as the next step? In my experience they are happy to replace at no charge. If Vodafone IT's new SIM doesn't work, just try a 3 ITA or TIM.

had this issue ONCE, and flashing the proper vendor file again fixed it.
no idea how or why

Thanks but I've already re-flashed factory image, so vendor is built in the restore procedure!

So I had an interesting experience with the same thing. Was running a custom rom that is very close to stock and updated to the most recent security update. Shortly thereafter, my carrier connection would drop (didn't notice at first because if I was connected to WiFi, it would be hard to tell). Only a reboot of the phone would fix it, for often no more than an hour or 2. So I started by wiping the device. Then I went to a different custom rom. And then finally, I went back to stock using "flash-all.bat" from the factory image. But alas, the issue continued. The last thing I did, which seems to have resolved it so far (12+ hours without a disconnection), was to relock my bootloader. Just in case it helps someone else. Is it possible that the new radio + an unlocked bootloader is causing the issue?

locked and unlocked bootloader,
hard factory reset,
flash google factory image and erase all internal storage,
wiped dalvic/cache,
flash vendor image,
flash different radio and bootloaders,
but still no service and no data. i think it's hardware issue and i have no warranty
