Returning SG3 to stock settings

Hi,
I recently purchased a Sprint SG3 on craigslist, but was unable to activate it through Sprint. They told me that the serial number in the phone was different from the serial number behind the battery which meant the phone was probably flashed to another carrier.
I have never rooted my android phones before, therefore am at a lost. The sales rep told actually told me about this website. So my question is, how do I go about restoring the phone to factory settings.. like if it was just out the box. Please help! >.<

Run this.(I'd go with the wipes data version).When it boots up it will attempt activation. If it still isn't working, open the dialer and hit ##72786#. Best of luck

Does the phone have to be rooted to do this?

Nope, it roots it and reverts to stock at the same time

None of what has been posted is going to help you. All the "reset" advice will not change the serial (MEID/ESN) back to what it originally was (behind the battery/back of phone).
What happened is whoever had the phone previous to you "wrote" a different serial (MEID) using software, either for the purpose of using it on a different carrier or what-have-you.
Since you're obviously new to this, the fix is to find someone who "knows" about these things to write the correct serial back to the phone (frowned upon here on XDA) because they have to physically connect the phone to a computer and use software to do this. Or you can just take the loss and sell the phone back on Craigslist and list is as a BAD ESN.
If you were local to NYC, i could help you out, but alas...

Lg g2 sprint ls980 no sim card - how to unlock it?

After hours of reading i decide to post im really stresfull with this situation. i bought a phone trough ebay i live in dominican republic but when i insert the SIM CARD say " NO SIM CARD" like if i had not put anything. i saw in the post that sprint has somehting modified to dont let no one activate the phone until we call them. i was trying to call them but there are asking me for a phone number and the phone doesnt have any phone number like the CDMA always do.
PLEASE!! there is any way to remove that security and unlock the phone without call sprint ?
if there is any how can i do that because i dont want to lose the money that i paid and im very needing this phone.
i tried lot of thing like the ##3282 and enable the LTE , BAND 26 AND 41 also i have my msl code but nothings appears to work.
Do i need to sell the phone for parts or i will need to wait till someone resolve this problem bz as i think is a software solution ....
Thanks for all

I think you should wait a little longer before selling it for parts as I think this is definitely a software solution.

Need unlock code from Sprint for international use... they unlock over network. Still, shouldn't say no SIM card, try another.

I've tried 3, all of them say no sim card.

Bottom line you shouldn't have bought the Sprint model. Sprint sends out the unlock code/unlocks the phone over their network and you being in the D.R, you're out of luck.

It's not as complex as you are making it out to be, don't crush people's hope if you don't have facts behind it. Yes it wasn't a good idea to get the sprint one, but the deed is already done. Both the S4 and the HTC ONE were unlocked without sprint sometime after their release, I believe it will be the same case for the G2.

...and you have the "facts" that the G2 will be unlocked or you just want to "believe"? This belief of yours is based on what facts exactly? The HTC One and S4 are/were much more massively popular devices and attract much more attention. You are chastising me for being a realist yet all you're giving the O.P is your belief, just that.
I'm not crushing anyone's hope (where in blazes did you even get that from ). Why suffer through the wait for an unlock when the choice is there for O.P to get rid of it for as much as he/she can still get for it and get the GSM version.

Pretty sure sprint g2 say no sim card because it's locked. Usually a phone would say invalid or ask for a code but not the g2. Cmiiw

Heh, learn something new with this phone every day.

Please help with the sprint unlock

Hi,
Happy New Year everyone!!
I'm in India and am getting a great deal on a Sprint LG G2. Only thing is that i have yet to find an unlock for it. Do the codes given by the unlock sites work? Or does anyone have any sort of idea/clue?
Please keep this thread alive. The price difference for me is substantial and I have kept my purchase of the LG G2 on hold for the moment.
If anyone can help I would be really grateful.
Regards,
George Mathews

sometimes they can also give you unlock instructions thro email so what I would do is call sprint and ask whats the worse they can say? all they can really say im sorry but we cant help? I would really just call sprint

I just got the tmobile model I paid 100 bucks more than the sprint model on craigslist. I dont have sprint service and they told me that i have to have a 2 year contract with them. That they wont do prepaid plans to this phone.. Ridiculous but that's how they work. As Sprint i dont think they will unlock your phone since you didn't bought it from them.

Sprint's international phones get unlocked OTA (Over The Air) while registered on the network, meaning the unlock codes/mechanism are sent to the phone from Sprint itself. Unlocker websites will not work.
Other alternative is to wait for someone to develop an unlock solution like they did for the Sprint HTC One and Galaxy S4.
...or get a proper GSM LG G2 variant.

Oh, you guys are going to laugh... it's so simple... edit /system/build.prop and change ro.build.target_operator=SPR to ro.build.target_operator=OPEN
THAT'S ALL FOLKS! I see this is from last month, but some may not know that yet, and I came here by Google search, because my stupid phone which is an active Sprint phone started showing no SIM card, and I can't figure out how to make it go away.

Edit prop file in systen folder and remove Spr in: xxx.carrier=SPR
Basically delete SPR at the end of the line. And your sim will work. Verified.
Hope this helps someone. I get so much from this forum and hopefuly I can give back.

How can I edit that part?

Download ROM toolbox which has a built in build.prop editor (You must be rooted to do this). If you're doing this, change the OPEN to spr (lower case) and then reboot, otherwise you will get system UI crashes.
But... there is now a permanent unlock for the ls980. Please check the Sprint section.

[Q] Do I need a SIM Card?

Im coming from the Note 2 which has a non removable SIM to my knowledge. I used a relatives upgrade so I think Sprint assumed I have a SIM. Question is: Will I need to get a SIM card to activate the phone?

All Sprint LTE phones come with a SIM card (paired with the MEID and/or IMEI of the phone). No, you don't need to get a SIM to activate the Note 4. It comes with one already and will be activated/provisioned on your account when you activate..

So I'm assuming that the phone will come provisioned to activate using the phone number of the relative whose upgrade i used? Is this something we can call sprint and have switched so it activates using my phone number? Thanks for the help.

It will come with the SIM in the phone. I came from the Note II as well. All I had to do was go online to the activate tab. Boot up the phone, let it do it's thing and was all set. Took less than five minutes.

AT&T sgh i747 will not read SIM cards

Hi I've been looking to xda for quite some time now for advice and help when I get stuck. First wanna say thank you! But I'm a new member so please correct me if I am posting in the wrong place or reposting. I'm aware that this is not a new problem, however, I have read till my eyes are bleeding and can't seem to find a fix. I have an sgh i747 AT&T gs3. I feel that this topic is unique in the fact that I have not rooted, flashed, altered or in any other way attempted to change this device. My fiance got the phone from her mom and I was going to try to use it with a straighttalk byop SIM kit. After activating the proper SIM with st the device would not recognize the SIM. I am now using that SIM in another phone. I get a constant ongoing notification in the notifications bar that says No SIM Insert SIM card. The device status is official and I have (as far as I know) stock ota updated 4.3 jellybean. When I insert a SIM into the device it doesn't prompt me to enter an unlock code. The only other SIM I tried to use is a sprint SIM card out of my freedompop lg volt. Don't know if that's compatible or not but I tried it and still the i747 acts as though it doesn't realize I've inserted a SIM. I called AT&T and emailed them. All I was able to give them was the imei as the phone number in my settings is unknown. The imei under my battery matches the imei in my device settings. They emailed me back within a few hours with my network unlock code and instructions for unlock. I haven't been able to use the code as my phone never prompts for the input of the code... I called them back later (this all happened earlier today) and spoke with a gentleman in tech support. I told him what was going on and asked him some questions. After doing a lot of research I started thinking that maybe my phone was already unlocked. Asked him to run the imei and said that it DID show unlocked on his end. That's one of my questions, if I still have an imei in my settings is this device still locked? The tech from AT&T told me it was probably the phone that was broke and I need a new SIM reader installed, to call Samsung. I tried to slide a little piece of paper in on top of the SIM that didn't work. I tried the dial code *#197328640# method, even though most posts say you must be 4.1.1 there are some who claim that it works on other versions. I tried a couple variations of this to no avail. I'm not sure what I'm overlooking here. If I'm leaving out any info that is needed to answer this post I'd be happy to include it just let me know. I need some fresh eyes on this thing it's driving me crazy I wanna get it fixed. I'm under the impression that I shouldn't attempt to downgrade this android version or I'll brick it... what the hecks goin on with this phone?! And again, sorry if I'm reposting but I can't find anyone who has posted yet that hasn't altered their device software in one way or another. I believe this s3 is completely official at this point. Thanks for any help you can offer

Is an sdcard recognized?
Was the phone ever used with a sim adapter? Sometimes, inserting and removing the sim adapter can damage the sim reader. Cheapest solution may be to purchase a new sim reader from eBay.

Sdcard works fine... and I'm pretty sure it's never been used with a SIM adapter

It's possible the sim reader has failed. Don't think you'll kn for sure until you are change the sim reader.

Yeeeah... I think I'm gonna attempt to change it right now and see what happens. I'll post back with the results. Thanks guys!

Fixed! Replaced sim port with spare one from an s3 sch I535 I had laying in the junk drawer with a broken LCD display. Posting this from my i747 on straight talk 4g. Sweet!

Glad it worked for you.

Yes and thank you again for responding to my post. This s3 is now rooted and titanium backed! Now excited to attempt to flash cyanogen mod later this evening. Thanks again and take care!

LG G3 D850 Update

Hello dear G3 owners, sorry if this is a repost
i have an LG G3 D850, living outside of the States, and i want to get the OTA Update, or simply install the MM, in the website they said, i do need the ATT Simcard, as far as i know the ATT is a line provider which will cost a whole new phone just to get one, my question is this, does an ATT sim card bought on Some online store, an Activated one can do or there is no chance to get the OTA or whatever method to update,
i have tried several Roms , but always had issues, from battery draining to some nonfunctional phone

i guess then there is no solution

Try to change time & time zone put that manually so that u telling u located in the states instead! U can do that going to settings> date and time and change them manually and restart the phone after changing it before heading to update this is just in case. Try that!

i have already tried that i even used an US VPN to see if it is my provider that blocks things, i removed the simcard tried all of that but no chance, on forums they said the only way is to have an AT&T simcard working

straight talk is prepaid service in the state, a mvno from tracfone that uses the 4 big networks att/tmobile/verizon/sprint to offer service/carrier u like most. It is really affordable!

yeah i hag samsungs , xperia and nexus also updated them with no problem but this D850 is blocked by AT&T as far as i know

did you try to update via LG suite?

AT&T simcard is required (gophone, and active)
Adding my 2 cents.
Based on my experience, you need an AT&T simcard, and must be active. The simcard can be postpaid or gophone (prepaid). The very first D850 update (the Lollipop update, software versionD85020f) can be pushed down without having your IMEI number associated with the simcard. Any subsequent updates will require your LG G3 in AT&T database. That means, when you activate the simcard, you need to input your LG G3 imei number. Otherwise update versions D85021r, d85021q won't work. I've tried it with 4 different AT&T GoPhone simcards. Update can be pushed down via wifi only.
AT&T LG G3 can't update via LG suite. I seem to recall tmobile's can (D851).
Visit https://www.att.com/esupport/article.html#!/wireless/KB425811 for more info on different versions available.
Good luck.
