Insert Sim card issue on FOXHOUND Revolver Ocelot - Galaxy S II Q&A, Help & Troubleshooting

Hello all,
Currently i am on FOXHOUND Revolver Ocelot and LPS modem.
Every 2 - 3 days if i leave the phone one without rebooting, the phone loses network (seems to have the icon of a circle with the slash across) and when i go to settings>wireless>mobile networks> i cannot get into the menu and it will just shows the message "insert Sim card to access network"
A reboot of my phone will solve this but it seems to come back after a few days. I cleaned my sim card and tried removing the micro sd card, didnt help. Checked the IMEI of the phone and it is correct too.
Not sure if this could be a potential hardware problem but not to sure what else i can try other than switch back to stock or try other custom roms.
Any help or suggestions will be appreciated.
Thank you.

Just thought i update my post so that it may help someone else.. i changed to the rom's LPQ modem by doing a reinstallation of the rom and choosing the LPQ modem and so far my phone is behaving well. After 4 days it has not lost network, so hopefully this is solved..

[Q] SIM no longer detected after flashing

This morning, I had my SGS2 working as normal, running Oxygen 2.3.2 (GB 2.3.7 AOSP).
I tried later on to flash the new CM9 ICS alpha for SGS2, And while it worked for a bit, after a while the phone stopped detecting my SIM.
Restoring my Oxygen NANDroid backup didn't help, nor did flashing new PDA/Phone/CSC via Odin to an official version.
Baseband and IMEI both appear normally in the settings/about screen.
I'd love any suggestion to make this issue clearer or how to solve it.
Thanks in advance.
Try taking it out, blowing it off and putting it back in

Same above, once I had the same problem and re-inserting the sim card solved it.

I had the same problem. I went to the operator and exchanged the chip. Now it works perfectly.
Yeah, took it out with the battery and tried reinserting, didn't do much.
Funny to think the SIM might have gone corrupt, but who knows.
Update:
Last night, Asked a friend to switch SIM between our devices. His SIM worked on my device straight, Mine wasn't detected on his.
Went today to Orange IL and replaced the SIM, worked like a treat.
So it was the SIM in the end, Not sure how it got messed up.
Thanks for the advice from everyone!

[Q] Phone doesn't read sim card anymore

After a normal reboot of my phone, it suddenly doesn't read my sim card anymore. When I turn it on, I'm not asked to enter the pin code and the phone doesn't connect to the network.
If I go into settings and change the pin code, or turn it off, I'm asked to enter the original pin code, so in that way there's still a connection to the sim card.
When I've done any of the above, the sim card seems to been "activated", and the phone connects to the network, and everything is as it should be until the next reboot. Then I manually have to "activate" the sim card again.
The phone has worked without any problems for a long time with the current CyanogenMod 9 custom rom and my current provider, and I haven't changed anything that suddenly can cause this.
Some suggestions to what can be wrong?
Does the sim work with other phones ? If so, it probably isn't a problem with the sim. In that case, try a factory reset in the first instance.
If that fails to work, try a fresh/clean install of CM9. If that doesn't work, reflash a Gingerbread stock rom & see if the problem persists. If the problem persists with a GB rom, then it's likely to be a sim/hardware issue.
The other thing that comes to mind is have you flashed a recent CM9 nightly ? This might explain it working OK previously with CM9 & not working now. Obviously CM9 is beta, and something funky might be going on with a more recent build/nightly.
I've now finally managed to find another phone and another sim-card.
My own sim-card works fine in the other phone - and when I put the other sim-card in my own phone it doesn't ask of the pin-code and it doesn't connect to the network.
So I believe my phone needs a complete reset - when I've got the time to do it...
One strange thing is, that at one reset earlier this week my own phone asked for the pin-code - but only once...??
I think I've found the problem. Either it's caused by Avast Anti-Theft alone or it's a combination of Avast Anti-Theft and CyanogenMod 9.
I believe it's the last one, because everything worked fine during the first time I switched from stock ROM to CM9, but then suddenly the error with the pin-code occured, and I could be caused by an update in the CM9 version.
But when I restored factory settings on my phone and started again from zero, everything was okay, and I was promted to enter my pin-code. It was the same when I restored my apps and data with Titanium Backup, but then when I installed Avast Anti-Theft the error occured again.
Actually I restored my phone once again just to make sure, and it was the same - when I installed Avast Anti-Theft, I was no more asked to enter the pin-code and the phone did not connect to the network.
So now I know what's wrong and maybe also why - but I don't know how to solve it...!?

[Q] Help no network after a reboot!!!!

Well as the title says.
Just rebooted my s2 and now when I try to do anything it says "insert sim card to access network" imei is fine serials fine and even shows signal bars but soon as try to make a call to drop signal and network completely....
have restored efs folder and even dne a repair.
changed base bands
reflashed new rom
tried different sims(and networks)
and still nothing
Odd that it happened after weeks of being fine and then just did a reboot and then this all happened
any ideas folks as to next move?
please someone must have an idea or two. to offer!
Well looks like I have fixed the issue after many hours of frustration..
Still have no idea what happened to cause issue in first place..
What I did was refresh my original backup
flash original STOCK rom via odin and this seemed to have fixed it. Are there any friggin better loctaion for these files as took 8 hrs to down load the damn thing!?
now re rooted, flash custom rom, flashed custom kernel of choice and than restored back up
everything seems ok(though my imei is incorrect now as says 004999010xxxxxx ,but am concerned it will happen again. Had flashed a modem several days before and updated a few apps . but at time of the issue occuring was just clearing caches then a reboot..

Wifi won't turn on & shows No SIM card

This has be happening to me the last couple days. I've done no changes to the software, I did a screen replacement a few weeks ago. Sometimes Wifi will turn on after a while or the SIM card will read and connect to LTE. Trying to decide if the phone is on its last legs or not. I'm on BareCee ROM, have always only used engine95's modified ROMs. Tried flashing the latest modem and the latest partitions if any changes. Also tried deleting the /data/misc/wifi/ folder as suggested in another thread stating a similar SIM issue with no luck.
Can you fix that?

Hi, please tell me if you fixed that problem, I have exactly the same problem right now with my D851 T-Mobile, at first the phone says no sim card, but the sim works with other phones, and I use the phone with wi-fi but since yesterday the wi-fi won't turn on, I did the most common steps, did a restore wiping all my personal data and apps, and installing the original firmware. And nothing happens.

LeEco Le 2 Freezing and switching off

Thank you for reading my question, really appreciate if someone can solve my problem.:angel:
I have a LeEco le 2 x526, in which i removed the stock EUI rom and booted a Custom Rom Lineage OS, everything was well and fine for about 2 months then one day suddenly the phone froze and switched off.
I tried factory resetting my phone, re-flashing the phone but nothing helped it still does the same thing, i have to hard restart my phone by pressing and holding power button, when the android boots all the time and dates are messed up after getting the signal everything is back to normal.
I tried restoring my phone to stock Rom by recovering from backup image before installing custom Rom but after installing, but the phone is stuck at first boot screen, even tried downloading stock Rom and tried that same result. I waited about two and half hours before giving up. If i try to install again Lineage Os it boots correctly with no problem. But can't restore it to stock Rom.
One thing i suspect when the problem started was that i change my sim card to a new one, before i was using Jio 4GLTE sim card in the phone & then i switched the sim card to Airtel 4GLTE. Is this due to the sim card or signal or my phone is having issue. The Airtel was alwasys my secondary sim in my phone but never used it for data Jio was my data sim card, now i am using Airtel as my data sim card.
Hello, do you find any solution??
