Hi Guys, I am having a weird problem that needs your help. I have been using my unlocked Nitro HD (P930) with the official stable CM9 rom. After hearing all the goods of miui, i gave it a try (with full wipe, data/factory reset, cache partition, and Dalvik Cache). After flashing it, the first thing that poped out said the network is locked and the page for sim unlock was shown. I thought the miui might re-lock my sim so I entered my unlock code. Then it said, "andorid.com has stopped". All i could do is to forget the unlock and went on to the miui home screen. After that my phone cannot pick up any signal at all. I used nano backup to restore my original CM9, everything seemed to work fine but it just couldn't pick up any signal. I went to mobile network settings to select the netwrok operators, it failed everytime. I tried entering 2945#*930# in dialer, it only said "Mobile network not available".
I tried to flash the same miui or my CM9 rom again, but my phone still couldn't pick up any signal.
Thanks if anyone can help.

Have you checked your APN settings?
you may need to reflash another baseband as CWM doesn't backup baseband so your phone failed even after restoring. I think you can find the cwm-flashable baseband on the forum.

I set and save the APN but the APNs page remains blank after I have entered things like PROXY, MCC, etc.

Thanks for the reply. I found Drumist's threat about those CWM flashable baseband. I tried the v10j and the v10f, but none of them work. Sorry for asking this dumb question but what should I do next?

Someone else commented before about their phone re-locking itself without explanation. The solution was just to unlock it again. I'm assuming you still have the unlock code?
The problem is that custom ROMs are incapable of unlocking the phone. You have to return to a stock ROM to perform the unlock, after which you can then return to a custom ROM. The stock ROM can be a CWM-flashable version for convenience.

1. 2945#30# is to bring up the sim lock page, where you can enter your unlock code. But it seems to me it doesn't work when your phone is already unlocked or you have a custom rom (just like what Drumist said)
2. I wiped it every time I flash a new rom just to make sure my phone is complete "clean", but I have no idea what it does :silly:
NO signal from the operator network
Hi everybody,
I have an unlocked LG NITRO HD - AT&T, I flashed MIUI rom, after finishing it did not open the phone!!
Then I flashed CM10, but the phone did not get any signal from the operator network :crying:, I changed the sim card with another operator but the problem still there!!!!
Can you help me ?

Seems you are having the same problem as I do. Simply flash back to stock rom and then enter the sim unlock code again, then your phone should be back to normal.
Hi everyone. I just want to ask a question about my s3. So here is the scenario:
I brought my s3 locked to rogers to a CP technician and asked him if he could unlock my s3, he then told me that he can unlock it even though it is in 4.3 firmware. I don't know what he did but the only thing that I know is that he upgraded my s3 to 4.4.2 and he also rooted it. When he gave it back to me, I can already use any sim card so I guess that the unlocking is successful. The problem occured when I got home, my phone says it is in emergency calls only so i tried to toggle airplane mode on/off if it would fix the problem and it fixed it, I can call my phone again but then after 30 secs of toggling airplane mode to off, it would eventually cant receive or make calls or text. But when i toggle airplane mode on/off again, it can receive or make calls and texts but after 30 secs the problem occurs again. I go back to the CP technician to ask him what's happening but when I'm in their area, the phone works like a charm. I don't even need to toggle airplane mode on/off. And it can also receive or make calls/texts in their area. But when I go back to our place the problem occurs again.
BTW, my ImEI is still the same at the back of the phone if this info is needed.
Thank you everyone and i hope my problem will be solved.

it is just after unlocking because i've never used it yet with its rogers sim card, this phone was just given to me by my aunt and I live in different country. Before unlocking it does not have this kind of problem, my aunt can use it with its original rogers sim card fine.
Btw. The baseband of my phone is I747MVLUNF2
Is the bootloader the same?
There is updated firmware on sammobile.com for the i747m.

You can flash a stock Rogers ROM. After that, you can install Philz Touch recovery, backup your current ROM, flash another a custom ROM (I like Liquidsmooth), and try it out. If you want to go back to stock, boot into recovery, and restore your backup.

Hi sir, I found out that I'm on the latest firmware already, it's 4.4.2 already so i don't need to get it from sammobile already, will i just skip the flashing on stock rogers rom step and proceed already in installing Philz Touch recovery to install a new rom. Thank you so much sir.
Connect via wifi and install any ota updates. Then install philz and a custom rom. You may also need to install gapps if they are not included in the rom.
Hello
I am currently running CM 12.1 on my SGS3 i747m.
I want to return back to stock rom, the current version offered by Rogers is Kit Kat 4.2.2.
Is this considered a downgrade? (from CM 12..1 to Android 4.2.2) Will I brick my device?
Is returning back to stock rom the only way I can network unlock my phone?
1) it is a downgrade in android versions (lollipop to kitkat. not bootloader/modem).
2) no , will not brick your device as long as not downgrading bootloader/modem.
3) what is your current bootloader/modem version ? (if unsure , you can DL the "samsung info" app from playstore and it will tell you).
http://forum.xda-developers.com/showthread.php?t=2609045
here's the xda thread for that.
4) i belive its the only free method. i think you can pay for an unlock code and not have to return to stock.
5) if returning to stock , here are directions posted by @audit13

"err on the side of kindness"
So you're telling me I do not have to revert back to stock in order to network unlock? =D
That was my only reason for reverting back to the stock rom.
correct. but i've never had to unlock one so i wouldnt know where to go or how much the code cost.
"err on the side of kindness"
***update: i just bought an unlock code
didn't work. my phone says perso lock.
sigh
if i revert my phone back to stock rom, does the recovery have to be reverted too? or it's all good.
Recovery can be custom or stock. You need to revert to the stock Samsung dialler in order to enter an unlock code.
Easiest method would be to flash the latest 4.4.2 stock Rogers rom from sammobile.com, skip through the set up, power off, insert non-Rogers sim, boot phone, enter unlock code, done.
could I install stock rom via recovery or does it have to be through Odin?
so... I tried to install the stock rom via Odin3 as instructed on Sammobile... but it gets stuck in the glowing Samsung logo during boot.
any ideas?
try thru recovery :what:

So I went back to flash the latest stock firmware... and I was able to access the recovery and wipe cache and then factory reset/wipe! it worked!
=D
but I am having the same problem I started. I couldn't unlock my phone.
I entered the unlock code I got from MobileInCanada.com... and it still doesn't work.
I see that there is a free method for Android 4.1.1.
I am currently running Android 4.4.2
From Phone INFO app
Bootloader Version/PDA/CSC/Baseband: I747MWLUFOB3
Do you think I can revert back to Android 4.1.1 and try the free method? Or should I complain to the MobileInCanada about unlock code not working. Seeing as it looks like going back to stock, everything should be easy as pie to network unlock.
So you flashed back to a completely stock rom, inserted a foreign SIM card, you were prompted to enter the network unlock code, and it didn't work?
The imei in the phone matches the imei provided to mobileincanada? I have used mobileincanada but it was a long time ago. I get all my unlock codes from eBay because it's cheaper.
Do not attempt to flash any rom that is 4.3 or older as attempts to do so may hard brick the phone. Once an i747m is running a 4.3 or newer bootloader, the phone can only be unlocked with a code.

Yes! completely right! I inserted my foreign SIM card, entered the unlock code from MobileInCanada and it didn't work.
I double/triple checked the IMEI.
Mobileincanada has a very good reputation. I recommend contacting them for a refund or have them resend the code.
Thank you!
would it be a different code?
If you supply the same imei, the code should be the same. Perhaps mobileincanada looked for the wrong imei in the unlock database.
The problem was resolved after flashing stock, reunlock, then restore. I will report if problems comeback.
Hello,
My phone was unlocked (not sure how, bought it second hand years ago) and used it fine on 4.4 custom rom. Ive updated it onthursday to the revolution 6.0.1 (with 3.0.2 twrp, nano open gappsa) and used it fine without problems on thursday.
However, yesterday, it lost cell signal and would not reconnect. So i rebooted the phone and now it is asking me to put sim unlock pin. What is the best course of action to get unlocked 6.0.1? I couldn't find an unlock method for 6.0.1. Should i backup rom, go back to 4.4, unlock, then restore?
Thank you.
It's asking for the sim pin or network unlock pin?
audit13 said:

SIM Network unlock pin. My modem/bootloader is I317MVLBMA3. Do you think i can safely load a 4.1.1 rom and unlock again?
If i install phone info+ and look under secret codes, it does list the code for unlocking, but if i click on it, it gives me a blank page titled "service mode" but doesn't do anything (none of the three methods of entering work under the app). Probably because it is not stock ROM?
I tried searching for stock I317MVLALJ2 ROM to downgrade easily, but it seems like the link is down. I guess ill have to use ODIN.
EDIT:
Can I use TWRP to flash http://stockroms.net/file/GalaxyNote2/SGH-I317M/I317MVLALJ2_I317MOYAALJ2_RWC.zip stock ROM? Or do I have to use ODIN? I am assuming I can as it is a zip rather than img, and as long as I flash recovery right after flashing rom, I shouldn't lose recovery either?
Thank you.
The easiest way would be to flash a stock 4.1.1 rom in Odin. I am fairly certain you can downgrade as I think I downgraded from 4.3 or 4.4.2 on a Koodo note 2 so I could use it on Rogers. If it's not possible to downgrade, Odin will stop.

Thank you for the reply. I am currently on 6.0.1, but since modem is 4.4.2 ish, i hope that's okay. I will try ODIN. The zip i mentioned above is not a TWRP flashable zip, so I guess I have to use ODIN. The thing that worries me, though, is the fact that I cannot get to the recovery mode from off. I press and hold the volume up-power- home combo, but it keeps on resetting without entering TWRP. The only way for me to enter recovery right now is using a custom rom restart menu. If I go to stock ROM, I won't be able to access the recovery .
EDIT: If I let go of the power button at a certain time while booting, it seems to go into recovery just fine.. The problem is, that timing is tricky.
For flashing a stock rom, you need download mode so don't worry about getting into recovery.
To enter stock recovery, power off and try holding power, volume up, and home. Once the phone boots, let go of power but keep holding home and volume up until you see the dead android, then let go of all buttons.

Success. Thank you very much. So I've done the factory reset and successfully rebooted the phone. Then applied the unlock method, which seemed to have worked. Does not ask for SIM unlock pin. However, it does not seem to actually lock cellular signal. It still says 'Emergency Calls Only'. I am on Mobilicity, which used to be AWS, but now I believe is under Rogers. I know mobilicity used to take a while to connect, but I doubt that is the same now. This may be due to the old modem, so I will try updating the modem back to the 4.4 one... wish me luck
EDIT:
Without the modem update, it just connected to mobilicity !
Now the issue is, whether this phone will re-lock again once I flash 6.0.1...
Thank you very much audit13 for your live help!!
I will post back in a week or so (hopefully I remember...) whether this unlock sticks.
The 317m does not natively support was frequencies. You'll have to software enable was support.
You mean it doesn't ask for network unlock pin?

Yup. It unlocked for sure. But that is no different than what I had before updating to 6.0.1. I've used the phone without problems on Mobilicity for 2-3 years.
Mobilicity is no longer AWS, so it has no problems connecting to the network. It just takes a while, especially with the 4.1.1 modem...
Now I'm just restoring the TWRP backup that I have made on 6.0.1 to see if the unlock sticks.
The unlock stayed for my phone when I installed a custom rom.

Yes, that was the case yesterday as well. It stuck for a day, but after the cell lost the signal once (zero bars, emergency calls only), the phone got re-locked.
Now that I have restored the 6.0.1 backup, the phone is back up and running with it unlocked. Now ill will see how long this lasts.
Thank you very much for your continued support
I am having this issue now.. but the strange thing is that I've flashed to the Resurrection 6.0 rom a while back and it was working fine. Until a while ago I was pokemon hunting and all of a sudden my network died and its been asking me for a sim network pin... I was getting the intermittent network disconnect when I was on the Pokemon go app too long but it would reconnect back to the network after a short time.. not sure if it has something to do with the game app. Well, now I've downloaded the latest Resurrection rom and flashed it again doing a factory wipe but still nothing. I'm going to try and flash the modem and see if that helps.
EDIT: forgot to mention I'm on Koodo network which is also Telus, I believe. But now it wants to automatically connect to the rogers network hence I'm assuming its asking for the PIN.
(edited for grammar)
This is really strange that this happens. I've unlocked a few note 2 phones and none of them have relocked.
Did you change the csc in the phone settings to Koodo?

What's the csc you mentioned?
Csc is a carrier customization file. If you change the csc, which can be done using a stock rom, you can choose the carrier for whom the rom phone was intended. I choose Telus as a carrier because they have very little bloatware.

Hi all, I've been battling this problem for days now. Airplanr mode is stuck 'Turning off...' and wont connect to my mobile carrier. Things I've tried:
Restarting phone with and without SIM inserted
Factory reset from settings
Factory reset from recovery mode
Flashed to the same build twice using the flash from SD card method (build 3.36.709.3)
Turned airplane mode on and off with wifi/mobile data/NFC turned on or off
I have no idea what to do next. I doubt it's a hardware problem as the phone detects the sim card when I put it in and asks if it's O2 pay and go or pay monthly, so it can even read it, it's just the phone wont come out of airplane mode.
I am on holiday without a PC but feel free to post ideas that requires one. Device is currently S-on and unrooted. I would rather not root or s-off the device just yet, and would rather stay on stock ROM as it's still in warranty. Problem is, it's in the UK and the warranty is held in Taiwan, which means sending it internationally to get it fixed. It's also a problem as there is a language barrier between me and their support for phone calls and their live chat button appears to always be greyed out.
Edit: I found this for the M8 which I think is in the right direction:
"Even I started thinking same way but it wasn't hardware issue.
I used ##786# to reset the phone completly (it did asked me my MSL/SPC) and everything was wiped from the phone. ( I am sure this reset is different from normal factory reset)
now my phone is up and I can toggle Airplane Mode On & Off however now there is another thing which I came accross
1. No roaming option or extended options in "Mobile Data" option under Wireless & Settings
2. No Network Sharing option
Even tried after running RUU_M8_WHL_K44_SENSE60_SPCS_MR_Sprint_WWE_Harman_2 .16.654.4_R2_Radio_1.08.20.0612_4_NV_SPCS_1.52_003 _release_384670_signed_2"
How do I do this with the M9? aLogcat comes back with no MSL so I need a free unrooted way to get that, and that # code doesn't do anything on the M9 either!
Edit2: Tried*#*#4636#*#*
Option is there to turn on the radio, but pressing it does nothing. Changing preffered network type does nothing either (I select any option from the drop down and the original choice remains). SIM is with O2. Currently set to GSM/WCDMA/LTE
Please help -_-
damn you really tried an m8 RUU on M9? please don't be stupid! it will never work lol. is your phone unlocked, so you could flash twrp recovery? otherwise you need to find a RUU matching your mainversion/CID. but this time not from m8 lol

The M8 RUU was a quote from someone having the same issue on their M8. Sorry if that wasn't very clear. I am running a fresh M9 latest RUU, I'm not dumb enough to put an M8 RUU on it and the stock flash utility (download mode) isn't either.
I still haven't found a solution to this. Can anyone help?
tried in *#*#4636#*#* on the menu button the frequency option? if you are fully stock, ask HTC, if they have no other fix, send it for warranty
I've tried everything in that screen. Here is what I have also tried today:
Bootloader unlocked
Custom recovery installed
Rooted
Model number and CID changed to developer model
Developer rom installed (android lollipop) same problem
Latest developer edition firmware installed
ViperOne 4.3 installed, same problem
Cryno... Something... I forget the name, but another custom rom installed, same problem.
It's fair to say that the problem is probably hardware related. The SIM card is detected, but the radio willnot turn on. In this instance, what is the most likely hardware cause? Is it worth replacing the sim card reader or is it more likely to be a chipset issue? I would be happier replacing the sim reader if the sim was not detected at all.
Btw, all the custom software stuff was done because HTC Taiwan said they wouldn't touch it. According to them it's out of warranty even though UK support say it's in warranty with the taiwan support centre.
