[Q] Sim card not recognized after LG P500 last update

Hi there,
Some days ago I posted this : http://forum.xda-developers.com/showthread.php?t=1144937
I didn't have any chance to fulfill my request, but it's not the important thing.
So, I have a fully functioning P500, except that sim cards I insert in it are not detected, I have a "No sim card" Icone in the status bar. So my question is simple, do you know or did you have this probleme? Do you know where I could ask my question to have answers?

which update are u talking about??

Nevermind, it was the 2.3.3 20g from LG leak. Indeed, LGMDP bricked my GSM in the NV2 backup process. Another LG P500 finally gave me his NV2 backup, I restored it on my phone and now it works.

i have the same problem.
and i have no idea where i can get NV2 file.
somebody help me please.

no service
just that I root my P500, I put the latest mik_os' CyanogenMod 7 and my phone turned on, works perfectly, but get the error "no service" and does not recognize any SIM card. I did update from the official version 2.3.3 (where I had no problem) to version CyanogenMod 7.
I searched all forum and out of solution and I found no solution to the problem.
please help me

Did you try another sim card? Once my optimus broke my sim, I had to change it

Sigh. Kindly click the link in my signature and downgrade your baseband. CM7 ROMs will NOT work with the new baseband (official 2.3.3)

This post saved my mobile. So i will put an explain here to someone who is having the same problem. Try this: Go to LGMDP v1.5 connect your mobile and make a nv2 backup. if the backup has less than 150kb the nv2 of your mobile is corrupted, so you will need one nv2 backup from someone. If it have more than 150kb, the nv2 is OK and this is not your problem. My problem was with the nv2 (mine was 15kb), after fixing, it went to 179kb.
Sorry my bad english, i'm brazilian =D

no service

doktornotor thank you, indeed you were right. I do not know how I missed that FAQ, but now everything operates perfectly

I can't find any signature for me to click a link in it, could you be so kind as to reply it to me?

Doktornotor has deleted his account. What links do you want?

I need help!
Hello guys!
I updated to LG stock 2.3.3 on my LG Optimus One. After, I upgraded to Cyanogenmod 7.1 (2.3.4 android).
I noticed that my GSM is not working. I changed my nv2.
I can see the network operators, but when i try to connect to them, my phone says: "Your SIM card does not allow a connection to this network."
Can someone send me a good NV2? Please guys, Pm it!
And i need advice in injecting the NV2 file that (i hope) you will send me.
Thanks guys!

Can anybody share P500 nv file?

it will work for cyanogen rom and stock froyo n if you want to use official gingerbread then use this backup and then flash new v20g baseband. if you have any problem then see doktornotor's baseband upgarde/downgrade guide

If your phone is on a prepaid plan, and the account has been inactive for a certain period (90 days-telus) not getting connectivity is because your account has been cancelled. Once you get your account reactivated you will get service and data back

Things like this is not always related to nv2, and nv2 repair should be done only after other methods have failed. And remember you can get into big trouble using other people's nv2 in the same country

My account is not cancelled. After the update everything was working perfect but around 2 weeks after i just lost signal on the phone. It sometimes works and sudddenly stops working displaying "Emergency calls only" but is not a coverage issue. I flashed the new baseband again and nothing. I downgraded to froyo en restore the nandroid backup and still i have the same problem. What else can i do? i think i tried everything i've read on related threats but nothing seems to work for me. I thought my nv file was corrupted but it is of the same size of the nv from a friend's phone working on the same network (179kb)

Hmmm could be a sim card issue. Set to network to wcdma only?

I don't think so. I tried my sim card in another phone and works fine and i inserted other sim card in my phone and have the same problem.

[Q] No signal anymore

Hey guys... I recently encountered a problem with my nexus 5. Suddenly my phone lost signal and it won't receive any more signal.I was on the latest version of PA on 4.4.2 ...... Now I factory reset my phone and it's stuck on phone setup... What do I do?? I'll try flashing back to stock later and I'll see if it's fixed... Also, before factory resetting my phone, I checked my IMEI and it isnt gone.... It was still there.. Strange... Any suggestions on what I should do? Also, I don't have a nandroid backup....

Still no luck
Guys... Returning to stock didn't do anything... Still the same problem... Now I'm stuck in setting up the phone since it shows that my sim is inserted and it's trying to activate the sim... But it stays there forever ... I'm pretty sure it's a problem with the sim holder... When I tried removing the SIM card for the phone, it failed to eject my SIM card... Now I have to find a way to get my sim out... When I use the pin, it only opens 1/8.. It's too small to fit anything in it... What do I do?? Running out of ideas...
I could give my phone for repair but I live in Dubai and I don't think there are any service centers here...

I'd suggest flashing factory and unrooting to see if that works and if it doesn't send it to be fixed

[FIXED] WIFI and SIM Card TOTALLY broken on OPO running Nougat

Hi,
To begin with, before all this I already had a wifi issue:
I had to reconnect to wifi networks every 5 minutes. After 5 minutes the wifi signal icon was still showing but nothing on apps etc could refresh, simply no signal.
I searched something on Google and found a forum post about someone having the same issue. He fixed the issue by flashing and installing a 'firmware' zip, file or whatever. This was for OnePlus One devices running Nougat so I tought, all ok!
So I flashed the file and since then a new (huger) problem showed up.
When my device was on, no SIM card could be find (And yes it's in lol..) and I can't turn on WIFI (When I do, it turns off automaticely after 5 sec.)
I tried a FULL wipe via TWRP, tried to flash the rom again (TugaPower) and NOTHING worked.
HELP! Seriously, I've been searching **** for 2 days now and I really need my phone.

Oneplus one acting weird

My opo fell in water so its screen was not working. My father gave it to a mobile repair shop who repaired it for 4k. When he checked the phone everything seemed alright.He was able to call me etc etc. Then he couriered me the phone. When I got It... It had cos13 latest version. I checked everything except calling. Then I rooted my phone. Flashed oreo. I inserted my sim. It was able to detect that it was an idea sim and import contacts from it but it showed no service. I thought it was the rom. I flashed Tugapower N49. Same problem. So I thought restoring it to stock might solve the problem. Used oneplus one recovery tool to restore it to 4.4 . Still the same problem. It can detect the sim but can not catch any signal. I check my Imei number. Its still there. But I was not able to run the ping test. Then I thought of using this phone for checking roms only and use my Lumia(I hate Lumia) for calling. Rooted it again. Flashed oreo. Flashed its gapps. It show installation complete but its stuck there...... Waited for half an hour. Forced restart. oreo opened but It was nt factory reset although I had wiped it and it shut down after some time. after that my phone reached the android screen only and cant proceed further. I thought maybe force closing my phone during gapps installation did this. Tried to install tuga power.. error executing update binary. Had one more nougat rom. Installed it. Again it didn't show that starting google screen which u see when ever u open a new phone. Basically It was again not factory reset, Wiped everything except system. still this happened. Returned back to stock using recovery tool. Now I tried to install multirom so that I can install the oreo rom. after rooting multirom wasn't able to download anything. Downloaded it manualy. Flashed multirom twrp using fastboot. opened recovery . Not working. phone rebooting. Flashed the previous recovery which I was using before multirom one, That one is working properly!!! What is wrong with my phone???!!!!!

It must be something with the hardware then.You've to disassemble your device and check if network antenna's broken.Follow the tutorial on YouTube.
