These problems occur each time one flashes a custom ROM or even when you do a factory reset. What you need to do is getMTK_ NVRAM TOOL.zip Use it to back up your stock IMEI number(s) and toto restore it after flashing a new ROM. It is very simple to use.

[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

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)

Need help to get IMEI, BT address back on MMX A110

Hi Dear Fellow Team members,
My MMX A110 had ghost touch issue. After trying out various options in XDA, I finally decided to replace digitizer and handed over it to a local technician who agreed to change digitzer.
He kept phone for 4 days and at last said to me that this is problem due to software and not due to hardware and since, I am using custom ROM, he is not able to do anything.
I took back the Phone and tried to flash stock ICS V1 ROM using SP Flash tool. First it was throwing error at various places, then I decided to format and flash. I formatted the EMMC (no NVRAM ) and then flashed the stock ROM.
It flashed well, but touch issue were not removed entirely, though it had reduced considerably.
then i thought to format full EMMC and then reflash. SP flash tool advised me to download instead of firmware upgrade and I did the same.
Post restart, I found 3 issues viz. NVRAM issue in WIFI, InValid IMEI & Unknown BT address.
I fixed NVRAM issue in WIFI by rooting and pasting WIFI & WIFI_CUSTOM files.
for Invalid IMEI, I tried using SN Write Tool 2.1124.1, however it stucks at step : select target to connect.
I tried with/without battery, only power, power + volume, but it never went past that. BT address is still pending.
Can someone help me to get past the SN tool or any other solution as well as I want to fix BT address issue as well.
Is it possible to find out various nos. (BT Address, WiFI MAC address, etc.._ using the device SN.
Please reply back with solutions.
Thanks a lot in advance.

Hi,
First I think you must have tried *#06# from your dialpad for IMEI. If not try that first. Then check out the below procedure
Hope you have rooted your phone & If rooted try the following.
1) Install Root Explorer
2) Using Root Explorer you must replace modem.img from the archive to this location of the phone /etc/firmware/.modem.img (do not delete the old file & just replace it). While copying if it says Access denied press "Mount R/W" on top right corner of the Root explorer.
Set permissions for the .modem.img file to rw-r--r-- ( Hope you know how to set it. Just press and hold for a while in the appearing menu select permissions and then move on ) . If permissions menu says access denied again see the top right corner and switch it it R/O.
3) Restart the phone and it might work & if not go to next step
IMEI information is stored in /data/nvram/md/NVRAM/NVD_IMEI/MP0B_001. Maybe changing of your original IMEI is not good idea because it is against the law but if you don't have copy of that file BEFORE the factory reset you can use temporary IMEI file located in the archive.
Will try

Hi Sansans90,
I had flashed multiple Custom ROMs earlier including CanGalaxy. since, I got Ghost touch issue, and technician told it is software issue and not a hardware issue, I flashed ICS Stock ROM V1 using SP Flash tool. Then I rooted it again in order to fix NVRAM, IMEI & BT Address issues after flashing Stock ROM.

ICS flashing is not needed. Flash official Micromax Jelly bean Stock ROM & after go to developer options and then disable all under drawing menu.
I have written a detailed procedure on how to solve the Nvram issue. Take a look. See if it helps.

It's not software. It's failing hardware. Your Bluetooth will also stop working, as it's the same chip. Mine does the same thing. I've flashed multiple ROMs and tried changing wifi system files. Nothing has helped...
Sent from my TARDIS
I bought my Nexus 5 the first month it came out. Since then I have never touched the original system or even root it. About a month ago my wifi suddenly stopped working. I have decided to root and flash roms, after factory reset and basic solutions on google didn't work. I have tried a couple of different roms all on android 6 and 7. Wifi still not working. I havent tried flashing kernel and I don't have a file called /persist in the main directory...
EDIT: Cellular data & Bluetooth working.
If changing software and resetting doesn't fix the wifi problem, it's probably a defective wifi chip. I have two nexus 5 motherboards in my desk drawer with no wifi (tries turn on but never does or turns on then off by itself) but cell and Bluetooth work.

No Data Connection

Hi everyone,
Could really use your help. I tried updating my phone to Lineage OS and post update, my phone's data connection stopped working. I've tried flashing different firmwares to see if it fixes the problem and it didn't. I went back to my old backup, and the problem continues. I can't access any data connection (no phone, or text either).
Any idea on what could have caused the problem. My steps were basically:
Backed up old Sultan 12.1 Rom
Installed Lineage using TWRP 2.8.7.0
Installed latest Gapps mini
Installed the bacon_firmware_update_2015_05-15_DI.3.0.c6-00241.zip
And data problems began
Now i've tried redoing the steps with the latest recovery and it doesn't change anything. And as previously mentioned, I'm having data connection problems in my old backup as well

Yup, I reverted back to my old backup and no flashing of firmware, and it's still messed up.
Found out that my IMEI isn't showing up so that could be the problem. Went through "the entire internet" and found some fixes, trying them now to see if I can get something to work.
Edit: I flashed to CM13.1 stock. But my IMEI is still not showing up. No idea what to do next. My phone connects to the network, but doesn't let me do anything considering it can't find an IMEI.

Most probably that is an issue with incorrect firmware.

Found out that my IMEI isn't showing up so that could be the problem. Went through "the entire internet" and found some fixes, trying them now to see if I can get something to work.
Edit: I flashed to CM13.1 stock. But my IMEI is still not showing up. No idea what to do next. My phone connects to the network, but doesn't let me do anything considering it can't find an IMEI.

It's not just your imei,it's your EFS and modem.
You should've backup your Efs before playing with things.

Yup, lesson learned. And I've tried a bunch of efs recovery solutions:
the persist flash you listed
The Windows fix patch from oneplus https://forums.oneplus.net/threads/no-imei-and-no-efs-backup.322534/page-2
deleting modemst files https://forum.xda-developers.com/oneplus-one/general/guide-efs-partitions-how-to-lost-t3307793
I had it partially working at one point but going through this solutions just messed things up more.

Type this command in fastboot.
fastboot flash sbl1 sbl1.mbn
Sbl1 from stock can fix the imei issue.

Are you talking about flashing stock from the thread you linked above? I'm not on the stock firmware from the fix above, I'm on stoch CM13.1.2.
Should I go back to stock CM11 from the fix above? Or can I just extract the sbl1 file from the package and flash it in fastboot?
Okay, I finally got my IMEI back using this guide: https://forum.xda-developers.com/oneplus-one/general/guide-efs-partitions-how-to-lost-t3307793, and flashing stock oxygen OS through their recovery rather than TWRP.
But now, although it reads my sim, my phone doesn't connect to the internet, and when it does, it doesn't connect to 4g. I still can't use data services despite having the baseband and IMEI fixed. So now what are the next steps? Could my hardware be broken?

I installed lineage, still no data connection. Honestly about to give up on this phone. Is there a good stable rom that I should use?
I've tried Lineage and now Sultans CM13, but still no data man. Just my sim stuff is acting weird, and i know my sim is fine. I'm switching carriers and ordered a new sim. I'm hoping somehow changing carriers helps, otherwise I'm **** out of luck.
Edit: Ok, so on Sultan's CM13 I've finally got the data working, but it only works when its on H+ (4g) otherwise no internet/voice/ text. So is there a fix this?

4G is Lte not H+(3G).
Yeah maybe OPO doesn't support the band your carrier uses for data.

Nope, not the case as I've been using the phone for the last 2 years. I read up that the switch between H+ and 3g happens because the carrier only sends data through H+ not 3g, so it happens to every phone, not just the OPO. But now my problem is, I can't send texts over 3g.
I'm going to wait and see what happens when I get a new carrier's sim.

you've mentioned that you are using twrp 2.8.7.0, can you try twrp from here and re flash firmware and report back?
Just flash the .img file via twrp
Also, use this firmware : link

He already tried using the latest recovery...
Thanks for the help guys, I think in this case it was more of a carrier problem. I learned that Wind has been updating their infrastructure causing some network problems. Couple that with a finnicky OPO and you get headaches.
My new carrier seems to be working better (but I've only had the new sim for an hour). Going to do a full day test and see what happens.
Thanks again.
