No SIM Card error on LeTV 1 pro X800. - Android Q&A, Help & Troubleshooting

So, recently I bought this beautiful phone that came pre rooted with cuoco92's rom. I put my SIM in and was ready to go. But I messed up with titanium backup and deleted the system phone app.I could still call and all, but the menu while in call was gone so I could not hang up etc.
Then I obviously decided to re-flash the rom. Problem is when I did so, the phone's signal icon was grey with a small x . From there it went downhill. I flashed the rom and some others multiple times, I even returned to stock rom+recovery, and the problem changed from what I described to a simple No SIM Card.
The phone now does not acknowledge the SIM when i put it in at all, while before it did know it had a sim inside, it just would not work.
Is there any universal troubleshoot process I can try before contacting the shop and sending the phone back? Could this be hardware?
Note that today I changed my micro sim to nano sim since the phone takes both, in hope of solving it. But it did not work on both slots.
Thanks in advance.

[Q] X10i upgrade R2BA026 restarts abruptly

Hi,
I got an X10i from UK Vodafone, and upgraded its firmware in India through SEUS, and it was clean installation to R2BA026, but the moment I started using it, every time I use some app the phone switches off. Its very inconsistent.
I tried below with no luck
reinstall
removed some apps
Killed some apps
I worried that many in talk.sonyericsson.com/message/10001 say that its hardware issue, but I dont think so.
Can anyone help with some solutions?
Mod's please move this if this is not the right place to post this.
Have you tried to OTA update your x10? If this won't work you may should root your phone or try to downgrade it to an older firmware!
SE will launch eclair soon, this will also fix phone!!!
I got exactly the same here. Phone reboots in a loop or even crash without a reason. Sometimes it couldn't come up, while activating SIM / phone. After that message appears the phone is still in loop and reboots again.
I am going to downgrade now to 024 firmware. It's driving me crazy...will post if I have luck.
Well I figured out, that the problems we have are a bit more strange as expected. I read that the problem is because of the overheated battery. Once happend, the battery isn't working properly anymore. So only SE Customer Service can help. Today I'm going to a Sony store to explain my problem with the phone. Hope I'll have luck.
I nearly forgot to post the details: http://talk.sonyericsson.com/message/12816#12816
I got the same problem and tried everything to fix it but nothing helped. As soon as mobile switches on it restarts and goes into a boot cycle.
I figured out that the mobile restarts mainly when it needs to read something from the sim card. I swapped my old sim with a new sim and found that the restart problem was solved instantly. I tried again with another bad sim and the restart loop starts again.
Bad sim cards slide into the sim card slot very easily and hence the pins connection are loose which tends to make the mobile unstable while reading or writing from/to sim.
The easy method to solve this problem is by making the sim a little thick by sticking a piece of paper on the back side of sim.
From my personal experience bad sim is main cause of restart cycle.
Try to swap sim cards, if it works let us know.
Thanks
Hi,
Thanks for the details.
I tried both the sim cards, I have GSM Vodafone, and BSNL 3G, both has the problem, very similar.
The same worked earlier with R1XXXX very well.
However, will try the Sim trick with a paper on the back side, which afix the sim tightly.
Thanks,

Hi,
I have tried the sim trick with no luck.
Some one help.
Thanks,
Naveen.KK
its not related to sim or firmware
it is not related to sim or software, it might me with some handsets but it is completely a hardware problem...dont believe me use your phone without sim and memory card and play some game or just keep on playing with your phone
it will turn off and you have to remove battery for few seconds otherwise it wont start
this topic is covered on sony site mentioned above and other threads, this is not just happening to me or some of us...its with many of us
changing firmware, sim , memory card tried everything no luck
m using iphone now and miss big x10 screen and better colors
One week ago I sent my phone to SE. I'll get a report with my X10 back. So till now I don't have heard nothing from SE. I'll tell you what's in the report, if I get it back. By now I am playing with my oldschool N80 :-(
Hi I observed one thing weird here.
I have reset the mobile, and when it asked for APN settings, i disabled MMS&data, phone seems to be working little stable, goto check for some time, and try playing games on it.
Thanks,

The MMS and Data settings seem to be the problem.
When I used my old sim which was disabled, it worked fine with everything. When I enable my APN and MMS settings in my new sim and start browsing the net and downloading stuff it restarts there.
I think the problem is somewhat related to internet browsing on mobile.
What app do you use to browse internet on your Xperia?

How to fix no SIM card error after rom installation.

Ok u flashed a rom and have No SIM inserted or no service or that kind of error.I found this fix trying out things for myself.Take out your SIM card ,turn on airplane mode,reinsert it and turn off your phone(not reboot but power off).Wait for 1 minute and power it back on.Tada!Should be fixed!:fingers-crossed:
Thank you!
Thank you so much! I was worried I was going to have to try one of the more complicated fixes I've seen here. I was puzzled because after performing Joseph230's procedure to root and "convert" an S4 from AT&T to T-Mobile (http://forum.xda-developers.com/galaxy-s4-att/general/convert-i337-to-m919-wifi-caling-t2896719) everything seemed fine and I reinstalled all my apps. Then, I get the "No SIM inserted" error out of nowhere!
After much researching I was losing hope of finding a fix guaranteed to work. Then I found your post and it worked like a charm! :highfive:
robermaldo
Thank You
Im so glad that this worked because I was losing hope that my imei or something was broken and I git scared then I found this and it actually worked I thought it was because 5.1.1 or something anyways thanks for the help I actually loged in my XDA account just to post that cause I just always use the browser
A coworker brought me his G2 that I have taken apart to fix many times before because it was having problems charging and turning on (black screen; rhythmic buzz from the vibration motor). I worked around that to get it booted temporarily but then the SIM connection seemed to suddenly fail. I replaced the motherboard entirely because some charge/power issues persisted and everything works perfectly EXCEPT that the replacement also doesn't see the SIM. Both are running stock LG Verizon Lollipop (assumed installed by OTA). No one was playing around with alternate ROMs or anything. None of the fixes in this thread help. The SIM slot is on the board so I hesitate to assume that the charge, mic, headphone flex PCB has something to do with it, but it is the only major common component (even replaced the screen again along with the battery, speaker, etc while leaving out useless components). Any suggestions?
Long version:
After a previous screen replacement it would only buzz when attempting to turn on or buzz repeatedly when attempting to charge until I loosened the black screw near the battery connector. I definitely narrowed it down to that particular screw, though I still couldn't say why (the previous tech who replaced the screen may have shorted the battery terminal near there). When he brought it back to me it was doing the same thing again even with the screw completely removed. Within minutes I had it booting just by poking around. Not sure what I did but I had to take it apart and poke around again to get it to come on after making the mistake of turning it off (went right back to buzzing). I'm pretty sure that the SIM card worked because he received a couple text messages when I first got it turned on (phone hadn't been booted in a day). After getting it to turn on I had to leave it on while reassembling, so I put the SIM tray back in when I was done. The owner was watching and asked why the status bar showed an "X" on the signal strength, so I told him that it was because you had to reboot after reinserting a SIM on most Android devices (as opposed to dual-SIM and iPhone devices). Though I couldn't turn off without causing the power problem, I could safely restart. Unfortunately, restarting only gave me the "Insert SIM" message at boot and nothing I could do would get it to see the inserted SIM. I tried many SIM cards but none worked. I replaced the motherboard expecting it to be a solution to both problems but only the power problems went away. The SIM card issue remained even though the SIM slot is built into the part I replaced and the part I purchased is supposed to be guaranteed, tested, clean IMEI, etc. I'm at a loss. I've taken out every unrelated component and replaced the screen again and replaced the battery so about the only thing that is common is the flex PCB with the mic, headphone jack, display connectors, etc running through it. Not sure how that could be a factor, but I'm replacing it too. In the mean time, does anyone have any suggestions for what could be wrong?
Update: A new mic/USB/headphone flex PCB fixed it. I'm not sure how that can cause the SIM card to not be detected, but I conclusively tested and that was definitely the problematic component: No SIM card detected on either motherboard with the old flex PCB, SIM card detected fine on both motherboards with the replacement flex PCB.

Hello, is your LG G2 still working with the new PCB flex?
Thanks a lot, this solution worked for me ?
i've done flash rom on Mtv Slash 3G 512 RAM Tablet, but no sim detected ....& i've followed your suggestion but no solution made...!!!
I had spent more than one month using CM13 based ROM thinking its ROM based issue. but this resolved the issue.
But now no sim issue has been resolved yet no mobile signals are working...
I have a vs980 or the Verizon lg g2. It bought it unlocked and I use T-Mobile. The data worked when I was on the stock os. I then got cm13 and everything worked good accept it wouldnt see my sim card or it would say no signal. And it had no info on the sim card in the about phone settings. So I tried a few other nightlys and nothing worked. I went down to cm12 and still I got the same error. I tried what you said here multiple times and it doesn't seem to help. Any help would be greatly appreciated. Thanks

I found a fix! Go into settings and select Mobile networks. When your in there there should be a "preferred network type" change that to global and there you go. Now I couldn't get that to work on cm13 because the settings would crash when you try to go into mobile networks. But I got it to work on cm12 just fine

I have a galaxy note 3 -n900 I flashed CM13 after which my phone keeps saying SIM removed/inserted... And I can't remove my SIM without taking out my battery. Also my IEMI no. is correct. So no problem there
THANKS!!!
I've spent the last three weeks dealing with various radio bugs and issues, clearing preferences, wiping caches, factory resetting, and installing clean ROMs. All it took is to set the thing into airplane mode? You've got to be kidding me!
Thanks a lot for the solution hackarchive! :good::good::good:

SIM NOT DETECTED! need help!!

HI GUYS, Im having an issue with my phone(HTC dna) that is getting beyond frustrating. I got the phone like a month ago off of something it worked fine for the first week..then one day randomly stopped reading my sim card.. Im not a total dummy so ive done and ruled out the obvious , my firmware was verison 4.09.605.4 I just updated it to the current one. 4.09.605.8 so i ruled out firmware being an issue. i then went to amazon and bought the new board were the sim card attaches and the audio jack attaches i just installed that yesterday and still nothing!!. I even bought a new up sim card tray still no.. when the sim card TRAY isnt installed i get a message when about a im card not detected ,ect. when i push the tray in that message goes away which indicates it is trying to read...but in the corner you see a sim card with x through it which means no sim card..I've replaced my sim card 3 times just to rule out that but my sim card works in my other phone just not this one.. When i first got this phone a month ago it worked fine!! no troubles.. Im on the ATT go plan..i put my sim in and nothing..but now it just doesnt work..ive tried hooking my phone to my computer and opening htc sync manager and tried doing the repair and nothing ive litterally tried and ruled out most of the obvious, Is this a known problem with these phones? Can anyone please!! help me with a solution i want this phone so badly..i love this phone!!..ill be waiting for replies..hopefully someone can drop knowledge to me! thank you!
I switched over to straight talk and had the same thing happen for awhile. Changed the tray and still didn't work. What ended up straightening it out for me was either resetting the apn settings or the new sim card i got. After I did those things it worked fine.

LG G3 accepts only one SIM card

Hey everyone,
I am an owner of a G3 but I switched my mobile service provider recently. When the new SIM card arrived I switched them but my G3 did not accept / see the new SIM card and there was no possibility to type in my PIN. I ordered a new SIM but the problem remained with the new SIM card. So I tried a lot of other (working) SIM cards from different other service providers but also no luck. So I thought maybe the phone has SIM lock and I tried another SIM card from my old provider but it also did not work.
The weird thing is that when I put in my old SIM card the phone appears to be accepting the SIM card. The PIN prompt appears normally, I can type it in, the phone accepts. There is just no reception which is normal because I switched the service provider. I also tried a factory reset, also no luck. The phone was rooted but I unrooted and resetted it. Is it possible that I broke something because of root?
Other than this problem the phone works perfectly. Has someone an idea or some experience with a similar issue and knows if it is possible that a phone accepts only one SIM card?
I have no idea what the cause of the problem could be and I am really running out of ideas ...
I would be very thankful for any ideas or suggestions!
Thanks,
Patrick
Or did maybe someone have a similar experience with a different phone?
Thanks!

Hi again,
I tried some more things but still nothing helped.
The things I tried were:
- unrooting the phone and factory reset
- reflash radios
- try completely diffrent rom (CM)
Still I have no idea what the cause could be. Maybe the sim card reader is just broken. Just weird that it reads my deactivated sim card.
I would really appreciate it if someone has an idea or some similar experience..
Thanks!

Weird problem with SIM card?

Hey everyone,
I'm giving away my LG G5 to a family member as her other phone broke. My G5 had a custom rom and had been modified alot but i took it back to complete stock now, everything works fine but the sim card. When inserting my family member sim card it comes up as sim card has been removed which is really weird yet it will show that it has reception on the phone and shows me 4 Bars but cannot make ANY CALLS or TEXTS because the phone thinks that there is no sim card there. Now here is the super weird bit, when I insert my Sim card in the phone it works just fine without a problem I can send texts, calls and go on the internet, I tested this for an hour max to see if it was going to happen with my sim but it never happened no error message? This is a really weird problem with my G5 I never had come across any problems like this before why is it happening now?
I need to get to the bottom of this problem. Does anyone had or have similar problems like this?
Thanks :good:
??
HI. Maybe the SIM contacts in G5 got loose, have you tried putting another SIM to check?
