[Q]Flashed LG Optimus G

I was wondering if I can flash a rom to my sprint lg optimus g without losing its flash, I'm currently using it with cricket

Yes you can, But make sure to back up all your data.
and do NOT flash any radios/modems.

thanks for the info, really appreciate it!!

Flashing ROMs should not change the modem or carrier specific flash data because that is stored on a special partition.

I had mine flashed to Page Plus and was wondering the same thing but I had to upgrade to ZVB so I decided to bite the bullet and try. I did the LGNPST and reloaded ZV9 that way then rooted and unlocked then flashed the updated radio zip with "ZVB Stock-Rooted" Rom (800mb zip) and followed the instructions on that thread, re-rooted and was able to maintain my flash through all that. All IS GOOD
Also, if you have an issue with the "Hands Free Activation" pop-up, look at my thread on it.

Could anybody who has flashed their ls-970 to Cricket take a second out and tell me how they activated it on Cricket? I see services online that will flash my phone to Cricket for $10, but Cricket staff said there is no way to activate a phone without a sim card. So how did any of you sign up to Cricket with your flashed phone without a sim card if Cricket says it can not be done?

[Q] AT&T Deactivated my SIM for Rooting / Flashing??

can AT&T deactivate my SIM or block my IMEI if they detect a custom ROM?....my SIM is not working anymore I Rooted . FreeGee'd and Restored to this ROM
http://forum.xda-developers.com/showthread.php?t=2419802
I got 4G LTE fine (after changing to a different "pta" APN) but couldn't call. Found out I flashed the baseband for the E988 instead of the E980. I went to CWM and flashed the proper AT&T E980 baseband after a CWM wipe and restore again....my Sim still wasn't working
I saw some things that AT&T can deactivate a SIM if they detect a break in...can i just buy a new SIM?
I used the LGFlashTool. flashed back to stock completely. (relocked and unrooted) and it still gives me the red "X" near the signal strength and it won't save APN's
contacted online tech support said that "AT&T deactivated my SIM card as they thought my phone was being broken into and they thought it was stolen" is this something new? can I just get a new SIM at the AT&T store?
i've rooted and flashed an (including my significant other, co-workers at various places of work and my own handsets) HTC thunderbolt, HTC rezound, 2 Galaxy SIII's, a LG Optimus S, LG Optimus V, ZTE Warp,Galaxy SII, and even a Droid Razr and I have NEVER had the provider deactivate the Sim card because of hacking.
was the tech support person "Andy" trying to scare me?..is it true?..or did I bork the SIM by flashing the wrong baseband the first time?...because my SIM still isn't working
any advice would be greatly appreciated!

Go to att store and get a new SIM card.

No just go in tell them your SIM card isn't working and you need another.. those people working at the att store don't care if your rooted or running custom roms.. unless your trying to do a warranty return...

sim card replacement should be free also

turns out....it wasn't the SIM card....new one was put in and it still didn't work..the guy looked at the IMEI and it said unknown....had no idea how it got there...but made a jab at LG for making cheap phones and said "theres a reason why we dont carry LG" .fortunately I was still in the return window process and got an exchange same day at a nearby corporate store...do you think it was something I did?
either way..not rooting or flashing until a year has passed

Thought I had read on some of the ROM threads that flashing an incorrect baseband can cause some major issues, such as wiping out your IMEI...

You simply needed to use LGFlashtools to return to stock and your phone would have been fixed. Always make a backup of your currently 'FULLY' working Rom that way if something goes wrong, you can return to stock and be up and running. What happened was that your baseband was incorrect after flashing the wrong modem. Flashing the correct modem didn't fix it fully because that partition became corrupt. Restoring a fully functional backup would have fixed that issue.
Glad you got your phone returned though. Hopefully they don't bill you when they see that your phone is rooted and hacked. They might.

oh no problem..they gave me a new phone because i returned it back to stock using the LG FlashTool

It was your own fault not the phones. Flashing an baseband not meant for your phone will cause this...

[Q] G2 LS980 (sprint) Roms

Ive been looking around the roms on the sprint section to find another stock rom that is already GSM unlocked so it can be used on t-mobile, like the Cyanogen11 one but cant find a definitive answer while reading through the roms and change logs of the roms. i know this might be a stupid anwsers and sorry if it is, but im not used to dealing with sprint phones and the TC method never worked for me when i have tried to do it and i have done it. any suggestios. thank you in advance.

I think for now it's a test it and keep a list of what works or if you try some post your results here I'm sure we are not the only two wondering this. cm11 works good great data speed for me on att but would also like a stock option.

The TC method never worked for US carriers. Have you tried the build.prop edit method? Should not be dependent on the rom. For a stock rom I find OpTimuS DE excellent. I used it previously with the build.prop unlock and now with the permanent unlock (but I'm in Canada).

Use rom toolbox (or similar) to edit your build.prop... ***case sensitive!!!!***
ro.build.target_operator = SPR
reboot
ro.build.target_operator = OPEN
reboot, then
ro.build.target_operator = spr
reboot
The last one (spr) is done because you will get system UI crashes if you leave it as OPEN.

I don't follow. Why would you have a Sprint sim in the phone?? If you do this with a Sprint sim in the phone you will lose data. If you flash a rom or back to stock, you have to edit the build.prop again to activate gsm.

Haha sorry I didn't mean to make that confusing. But it didn't work with the T-Mobile Sim either. The only time I have been able to get any type of service bars instead of a red x over it is when I put the sprint Sim in and go back to bare stock

Actually now when I put my T-Mobile Sim back in, it shows all the service bars Grey but can't choose and operator or send a text.

You can use the app Tweakker to enter your APN settings.

the phone wants to resort back to cdma for phone service, grab an app called telinfo from the play store and use it to set your phone to GSM (auto PRL), then set your APN to get data working, best of luck!

[Q] LG-LS970 possible to unlock yet or prepaid atleast?

Is it possible to unlock the LG-LS970 without tearing the phone apart and soldering a sim card in it? Or atleast get a prepaid plan with it? It use to be a sprint contract phone.

You can flash the phone to change the nv settings and allow use of it on a prepaid network such as Cricket or Metro PCS There are other networks as well such as Ting (I think you don't even need to flash to use Ting) https://ting.com/byod

I was wanting it on StraightTalk. I've seen people have this done while searching but I cannot find out how to do it. I'd like to do this without having to sodder anything.

I have just purchased an LG OG that seems to have been flashed to Page Plus Wireless while the seller said it was ready for sprint activation, any idea on what I need to do to revert back to sprint?

Might need to be flashed back depending on how the NV items are held. I flashed an HTC evo once to cricket and when I did a hard reset the flash went away. You can try a factory reset through recovery.
But first I would check the esn to see if it will even be accepted on sprint. A lot of times phones get flashed because they have a bad esn with sprint..
check it here.
http://swappa.com/esn

Thanks for the reply. I purchased the phone via swappa and it passes their ESN checks, I also called Sprint customer service and they also verified that the ESN is clean. However the chat representative claimed that it must still be active on some other carrier.
I have also used kitty wireless's meid check and it comes back as active_with_ppc and has what i assume is the old owners phone number. Any ideas? Is it as simple as flashing the correct stock rom/radio/prl and then going through the Sprint activation process?

Glad the ESN is good for you.
I think the issue you might have is that it is still active with another carrier. You can try to run through the process of flashing it using qpst. I think the settings for the other carrier are still there.
First try to flash the radio and prl and add it to your Sprint account. But like I mentioned, Sprint doesn't like when the phone is still active on any network, you may have to contact the buyer to remove the phone from their account.
Is the phone rooted? What ROM is on it? What does it list for Radio and PRL now?

Try to flash the ZVC radio and do a reset on the phone. Looks like you might need to flash some files using QPST. Also since you are on a stockish rom try to update the PRL within system updates. It might pick up the current Sprint PRL of 25019, that should help with activation. I don't know if it will pick it up since you are not on Sprint at the moment but it's worth a shot.
If that doesn't work, find a way to flash a newer Sprint PRL with QPST (I don't think you'll find 25019 on the net yet) then try to update it on the phone.
You might try some of these codes too to see if you can do some NV changes, seems like the one for network reset or clear OTA provision might do the trick, I stongly suggest you make a full backup including an EFS backup first before doing anything.

Looks like the phone is still registered on Page Plus, I had KittyWireless run an ESN check and the MEID came back registered to another number and the status is ACTIVE_ON_PPC. Looks like I'm going to have to return it unless I can get the original owner to cancel their Page Plus account.

Flashed the ZVC.bin, phone rebooted and after conneting the USB it rebooted again to a black screen. Hard brick I am unable to boot into fastboot or download mode. Any fix besides JTAG?

Could anybody who has flashed their ls-970 to Cricket take a second out and tell me how they activated it on Cricket? I see services online that will flash my phone to Cricket for $10, but Cricket staff said there is no way to activate a phone without a sim card. So how did any of you sign up to Cricket with your flashed phone without a sim card if Cricket says it can not be done?

Sprint G2 GSM UNLOCK (US Carriers) Easiest Method!!

*YOU MUST BE ROOTED AND USING AN AOSP ROM*
CM11/PA/PAC-MAN/LIQUID SMOOTH will do the trick.
*Pop in a US Sim card (Tmobile, AT&T, H20, Family Mobile etc.)
*Open dialer app
*Dial *#*#4636#*#*
*Choose Phone Information
*Scroll down until you see the Network Type
*Click the box and choose GSM ONLY.!
And that's it folks. You will see the service bars appear after about 2-3 seconds. Set your apns if not already set and enjoy GSM carriers on your Sprint G2.!

I got the "No service" signal because it isn't activated, but at least its detecting the sim card Thanks for the info! Oh, & I was using the CloudyG3 ROM version 1.2 & it still worked

No LTE, since the needed bands are missing from the phone. But yes, 4G (HSPA+). Several weeks now on Cloudyfa G3 ROM v1.2. Pick "WCDMA preferred" in the mobile network settings, and choose the T-Mobile APN without LTE, although the LTE one seems to work OK as well. If you have any issues kick-starting the GSM radio you can download Radio Switcher from the Play Store.
The only issue is that some of the T-Mobile towers haven't yet been "refarmed" or "unlocked", so on this device in that case you would only get 2G data. For example at home I get HSPA+, but at work only Edge/2G. Hopefully that will change in the coming weeks to months as T-Mobile continues to upgrade its towers. The same issue applies to a Sprint iPhone 4S and Republic Wireless Moto X that I unlocked and am running on T-Mobile as well.

Guys I'm new to this rom update business, I mean I have done plenty of windows phones but none of the newer androids.

Sorry cannot provide links I m on the go. First you need to check if you are on latest ota which is zvd. If you're on zvc root with latest iroot. If on zvd search the forum there is an apk which you just install to your phone and run it (called towelroot). It roots even without reboot. Then search the forum for ls980 permanent unlock and follow the guide. Just use any root explorer to copy the files, restart and you are unlocked but with no speed data icons on status bar. The other way, is after rooting, install autorec (search for it - it's tricky, you might brick). Autorec is needed to install custom recovery. Then just pick a rom from cloudifa (g3 port is great with no bugs). His roms are made for gsm and you will be already unlocked. If you prefer aosp based, only one that worked for me after changing some settings and restarting is Omni. Couldn't make carbon (discontinued), vanir and mahdi to work. They didn't even recognize that a sim was inserted. Before flashing a custom rom, make a full backup via custom recovery and make sure you get familiar with how you enter recovery and download mode with hardware key combination. Keep in mind there is always a chance to brick and then you will have to enter download mode and flash back to stock with lg tool. If you are confused ask any questions and I ll try to help when I get home on my pc. Did all above a week ago and ended with cloudifa g3 port and is working great so far (I'm in Greece).

Thanks very much for your help and advice, I can get as far as unlocking the device and it all works However, how do you enable data? If I can enable the data then I'll keep the normal ROM and use it
Also after installing a custom recovery, the autorec works great and I can understand the concept of it, but then when I flash with the cloudifa g3_1.2 it flashes but when the phone restarts it gets stuck (first time at 49%, then had to reflash using stock via LGFlashTool, then second time at the LG logo) so I have to go back to the stock rom, root it, unlock it and back to square one. Unsure what to do next?

Thanks very much for your help and advice, I can get as far as unlocking the device and it all works However, how do you enable data? If I can enable the data then I'll keep the normal ROM and use it
Also after installing a custom recovery, the autorec works great and I can understand the concept of it, but then when I flash with the cloudifa g3_1.2 it flashes but when the phone restarts it gets stuck (first time at 49%, then had to reflash using stock via LGFlashTool, then second time at the LG logo) so I have to go back to the stock rom, root it, unlock it and back to square one. Unsure what to do next?

In order to enable data you have to check your apn settings. If there are no settings, try to set it manually (Google your carrier's apn settings). When you are done and you get data to work try a reboot to see if they stick. I think in the permanent unlock thread you can edit this file with the apn settings and add your carrier's ones. Also delete those 2 files so you can automatically have data after each reboot.
Now I didn't really understand what went wrong while trying to flash g3 port. Have you flashed the appropriate baseband? It's very important in order to boot. It's mentioned and there is a link as well in the op of g3 thread.

Bought this phone on eBay few days ago and I started checking around about how to unlock it(though it'd be simple as any other phones, but I guess I was wrong). Found few threads talking about how to unlock it for US GSM carriers but barely find any information about using it in Canada.
Looking to root\use a custom rom and read that the CloudG3 rom will actually GSM unlock the phone,but will it work as well for Canada(will be used on Telus network)
Thanks.

As long as the band's are supported it should work.

There's a Rom on xda that converts the spring variant to the T-Mobile variant by flashing the Rom. It's basically a T-Mobile variant g2 cm11 Rom but with a Sprint boot.img and a few other Sprint files to make it boot. But if I'm not mistaken it has the T-Mobile radios in it. That should get you their full network experience.

Think this thread might be dead but if I get a reply it'd be great. Will the OP method work on the latest CM12 nightly? Or does AOSP here refer to only the CM11 variant?

Currently not the Device Maintainer for the G2. I'm working with the G Flex community now. I'm pretty sure there's a CM12 nightly already released. Updates will be posted in whatever thread you originally downloaded it from
