[Q] LG OPT 2X - First Access WITHOUT SIM Card

Hi all...
I'm from Italy and I'm using LG P990 with VODAFONE ITALY...
I've flashed my dual 2 times... I haven't an internet flat up to
now on my phone, so every time I flash a rom ( every rom u
can think ) I find preinstalled some APN ( italian or others )...
And my phone, after first start up, tries to connect with the
APN set by default...
SO... 5 € !!!! Every time...
So my question : AFTER FLASHING A ROM, THERE'S A WAY 2
ACCESS THE PHONE ( APPS & SETTINGS ) IN ORDER TO DEL
THE APNs ????

You could try booting in Airplane mode and disabling Data Connections. Not sure if Airplane Mode is an option without a SIM card though...

Tried last time... No way to enter app / settings menu...
Every time phone asks me to enter sim' pin and tries to connect

Airplane Mode is usually accessible via the Power Menu (by holding the Wake/Sleep button).

i had this problem too...!then i change my 3g conncetion to 2g..disabled the data connecion and after flashing new rom it cant connect to my data and asks me for wifi connection!
this settings is saved for each rom i flash..!try it...

Thats if he doesn't wipe data

Ya of course, but follow me :
* I flash the rom
* first start up of the phone
* I press power
* airplane mode
* I can see LG first start up for some seconds
* I set time/date formats
* I skip new account registration
* first start up ended
* PHONE ASKS ME FOR THE SIM PIN IN ANY CASE
No pin ? No access to the menu... Even in airplane mode...
I've tried... And when I insert the pin, I've no time to
enter in settings and disabling data connections... LESS 5 € AGAIN !!!!

It's not a good idea changing rom without wiping data...

Is 'keyguard.no_require_sim' in the build.prop file set to true? If not, set it to true .

it's only for the first boot or for any boot?

When you are at account registration you can press menu and enter APN settings

Which ROM are you flashing?
EDIT: But then again, you might not be able to change the APN when no SIM is installed. Perhaps cagra's method works for you.
EDIT2: Still I do not understand your problem fully. When you dont enter your Google Account and do not browse, no data is used. Do you enter your Google Account before entering the PIN code?

There's a option backup and restore apn setting in titanium backup.

I'm using IPMART Italy - 2.95 Peppedroid's Rom... Trust me, even if I skip signing 4 account, after inserting pin, phone tries to connect and I've spent 5 € a time for both roms I've flashed... But trying with a cyanogen rom it's the same...

A funny walkthrough!
When you flash a new rom you can go somewhere you dont have signal...then boot your device and change data settings off

Can't you just call the phone company and ask them to disable internet access??

Usually you can request them to block any mobile data, friend of mine did that in Germany not too long ago. WiFi will work of course.

[Q] phone lock

I need to give this command from my laptop to my phone "am start com.redbend.vdmc/com.htc.omadm.test.TestMainActivity". can u guide me how to do that as my phone is asking to enter phone lock code.

Assuming you're trying to GSM unlock, you need to be rooted and do that command in Android Terminal Emulator.
However, you can just use this and it will do it automatically.

Same issue
I have an unlocked Sprint HTC One M7, but it kept dropping the network. After some research, I was led to believe that if I changed the setting to WCDMA Preferred, I wouldn't have to keep selecting T-Mobile as my network. I dialed *#*#4636#*#* and changed the necessary setting, but it did not work. THEN I became curious and accidentally selected some kind of lock. I erased my entire OS and had to flash a Stock Rom (Rooted and Deodexed however) using OTG/USB. BUT THE PHONE IS STILL LOCKED :crying:. Someone who knows what they are doing please help me with this $500 Paperweight. I'm learning the hard way apparently. BTW, I don't care about the SIM unlocking issue anymore. I just need to be able to use the phone.

You should've seen this thread. Anyways what does the phone say? Can you get into the OMADM menu again and select what you pressed again and see if that unlocks your phone?

Kk. I've tried to do the fix even though it probably wouldn't affect anything, and it didn't work. It might've been because I was on 4.4.2, and the guide was probably made when Jelly Bean was out, so Sprint might've patched it. Anyways, let me know if you get it working and post your steps on how you did it if you followed it differently.

[Q] I think I hard bricked my N6

Hi there,
So I just bought a brand new N6.
Did nothing to it, did not unklock the bootloader, di not flash anything.
Just ran it a first time, set my account, donwloaded the 5.1 OTA when proposed to and then it was over.
After the OTA installation my phone displayed a dead android and "Error".
When rebooting my phone, the apps are "optimizing" undefinitely and then the phone will restart.
I tried factory reset from recovery, that did nothing, I mean, the phone will still bootloop endlessly.
My bootloader is not unlocked so I cannot flash my phone..
Is there anything I can do ?
Thank you in advance

Well, since you haven't enabled OEM unlock, there's not much you can do besides RMA at this point.

unfortunately, that might have been your only option. as you need to boot up first, to enable unlocking of your bootloader, to reflash the factory image. and you cant boot up

id get the phone refurbished, from google or from motorola, since it wasnt anything that you did, but was the updates fault. btw, that happens, very rarely, but it does happen that updates can cause issues.

Well thank you anyway, looks like I have no other choice than send the device back.
One last question, since my phone won't stop rebooting endlessly is there any way to turn it off ? Long press on power does not do anythng, it will stil restart...
Edit: I found how to turn it off through bootloader.

Sorry to come back on this thread.
So now I have noticed that when in fastboot, if I type "fastboot oem unlock" I'm getting the popup proposing to unlock bootloader.
As I never selected USB debugging nor enabled developper option when my phone was working, I doubt it would work properly.
Would I have any chance to recover my phone if choosing to unlock the bootloader ?

yes! if you can unlock the bootloader, then you can flash the factory image via fastboot while youre in your bootloader. which would fix you not booting

grab a factory image, and read directions for flashing a factory image. you want to flash each individual file inside separately, instead of using the flash-all script.

It worked !! IT WORKED !
I love you xda ! really do love you.
Thanks a million.
(Although it's a bit strange that I was able to unlock bootloader without usb debbugging mode enabled no ?)

This is very interesting indeed. To the OP, where did you purchase the device? I find it very peculiar that you were able to issue the OEM unlock command without using the toggle in settings.

No wifi and now sign-in loop.

I'm stock running 5.1.1, my wifi stopped working after install. I did a factory reset, cache wipe etc.
This didn't work and now when I start the device it asks for the language, wifi connection (Which doesn't work) and ask me to login with a google account previously synced with the device. So, I put my details in and it boots me back to the wifi connection screen.
I haven't changed my google password and as I'm stuck in the no wifi-loop. I can't access my settings, which means I can't access USB debugging to install 5.0.
My phone is essentially a brick? :crying:

In my N6 there is a folder 'persist/wifi' and that folder is empty.
When you have a data connection at your telecom provider you can go to the play store and install a WiFi fix app.
When you are rooted you can also change/add in build.prop the value of WiFi.supplicant_scan_interval.
When it is not there add it with the app 'build prop editor.

Lost Volte after flashing

So one evening i was flashing a test build of a popular rom, there was some failure and i got black screen on boot. No big deal, i flashed previous build and all was ok till i noticed my volte icon had not reappeared.
I always had volte working on aosp roms and miui (after putting in dialpad code) but now its been a week and it hasnt returned.
What i have done to try and fix (unssucessfully)it in order
1) format data clean flash vendor firnware and aosp rom
2) use mi flash to flash latest stable 11.0.5.0 cn rom (i have a china phone)
3) flashed older pie miui builds, used dialpad code, waited an hour+ and no volte came.
3) other sims in my phone dont get volte anymore, the carrier said the phone is telling my sim it doesnt use volte.
4) I found an old twrp backup I had with efs, modem and persist backuo from months ago, restoring dint help.
5)added apn with ims, dint help
6) flashing global vendor/firmware, updating cn vendor/firnware
Anyone have any idea how to get the function back? Here are some pics to give more info.
When I make calls LTE turns to H, and if i put only LTE, i cant make or get calls

I can't talk for anyone else, but from my point of view, I can't think of anything else to suggest, beyond what you've already tried. I don't have much knowledge on the radio side of things and the different partitions dedicated to the radio.

Strange thing is that on your screenshot you have volte on . On my phone i have it off and im unable to turn it on without the build.prop mod.
You may have conflicting lines on build.prop or blocking lines. Maybe something else entirely , try not to brick your phone lol. Volte not worth it
