[Q] T-mobile G2 camera app won't run (Craigslist purchase gone wrong)

So picked up a T-mobile G2 from a guy on craigslist. I forgot to check out the camera before I paid up. I came home and cannot get the camera to work at all. the camera app crashes everytime and I have to force close it. The dedicated camera button also does nothing at all. Have tried doing a factory reset a couple of time and have no luck.
Any ideas for options? I am pretty sure the warranty is not in play as I am the second(third /fourth) owner.
Looks like its running the stock firmware
Android Version
2.2
Baseband Version
12.28b.60.140eU_26.03.02.26_M
Kernel Version
2.6.32.17-g9ab3677
Build Number
1.22.531.8 CL277427
Thanks in advance

Did you try a 3rd party camera app to make sure the camera works?

No third party camera app works either. I think they all use the base app in the background or something.

At this point since you cant get your money back you might as well root it and install a different rom and see what happens.

Well I ibuy all my phones off craigslist and I can get replacement from tmobile. Worked for mytouch 4g and worked for g2.
Please click thanks button
U must be willing to spend sometime on this...
Won't work unless ur a tmobile subscriber.
1.go on tmobile website, log in, go to contact us and online chat.
2.find the one that says trouble shooting
3.fill out ur info
4.tell them you recently bought a g2. (Don't say like 2 weeks ago or anything like that, tell them you bought it yesterday) and obiviosuly don't tell them you bought it off ebay or craig. Act like you bought it off tmobile store.
Tell them you have a friend and he had his g2 for a while and he's firmware version is different than yours. Tell them he received an ota upgrade sometime ago. and you still haven't received your ota update. So you took it to the store and everything and they told you to contact tmobile and see if your imei number is in their system. Now they will require your imei number. Give them your imei number and they will tell you they updated in and ur imei number is now in their system.
At this point their system will think you just bought the phone as it just registered on their system. So its like your on tmobile 14 days remorse return thingy. I forgot what its called.
Now exit the online chat.
Now this time choose phone acce then warranty exchange.
And tell them you are experiencing weird reboots problem. Tell them the phone reboots by itself like 5 times a day. And you found a dead pixel on the screen idk make some stuffs up
And tell them you already took it to the store and did hard reset and eveything and your still experiencing problems.
(This is a must part or they will walk you through hard resetting the phone steps and tell you to contact again if you're still experiencing problem)
Ur done. They will say they will send you the replacement phone at this point.
Just make sure you still have the void sticker and u don't have any water damage. Or you will get charged.

Strange, some others have mentioned it, have you tried rooting and installing a custom rom? Or is that something you didn't have interest in doing?

Hiw sure are you that this will work on a G2 that was purchased back in October? I have a legitimate problem....traded my N1 for G2 on craigslist and now the screen is white w/black lines. I have a custom ROM installed (but didn't tell them that). I called and they said it's not under warranty (since I'm not the original owner). I'm guessing that conversation is in the system, but I'm willing to try this method. This seems incredibly sketchy and it seems like they would have the phone in the system on the original owner's account.

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...

[Q] No IMEI

I just purchased this phone a week ago off of Craigslist, the phone worked great up until today. I noticed that I didn't have any service. I use a microcell at home so it was no big deal, thought that it had messed up like it does every now and again, however I got out to town where I usually have near full signal and still had none. I opened up settings and "Mobile Data" was turned off, I tried to toggle it back on and it will not allow me to do this. I went in to the "About Phone" part of the settings and the phone shows "Unknown" for cell phone number and IMEI.
This is the stock AT&T version G Pro that has not been rooted. I contacted AT&T thinking this may be a sim card problem or maybe I bought a stolen phone, but everything on their end seemed to be clean. I tried out a friends sim card and still had no luck. Called LG and they said I would need to send it in with a receipt. I don't have a receipt and I won't pay for them to repair the phone, because I'm sure the bill will wind up being more than the phone is worth.
Has anyone else had this problem? Are their any fixes anyone can think of that doesn't involve rooting the device? If not, what steps will I need to take to recover my IMEI so that the phone will actually make/receive phone calls and texts?

Are YOU SURE you did not do anything to the phone? Cause loosing an IMEI requires the USER to do something wrong, like flashing other carrier Versions.

I've had my phone do that before. Wasn't rooted or hacked in any way. I didn't even know of a way to do it. What fixed mine was a **** load of factory resets. And I mean a **** LOAD!!! Luckily it came back and I've been good ever since. Don't know what happened or how but that was very weird.
Note to the wise: I don't care who says what about what! NEVER buy a phone off of craigslist or from anyone for that matter other than a carrier or authorized reseller. Because when it breaks, you can't do **** about it!

Well I have no reason to lie about something like this. I've only rooted one phone of the dozen or so I've owned and that was a old Galaxy Note.
This morning when I got home from work the phone had 76% battery left, woke up and it was dead. It powered up and showed 2% battery. I went into battery under settings, android system used 26% of the battery. Not sure that's enough to drain the batter while I was asleep.
Must be something definitely wrong in the phone.

Yeah, lesson learned. Craigslist is usually where I do my cell phone trading and buying.
I'll keep trying resets to see if this fixes the problem. Thanks!

Try to re flash a stock using an LG flash tool it might work as what other users did on their G Pro have the same issues

Still haven't found anything that works.
I'm guessing something has malfunctioned in the phone.

Sold my LG G3 to another T-Mobile user - IMEI doesn't match the box?

Long story short, my phone was rooted and I flashed one of the rooted base roms a couple of months ago. After having issues with T-Mobile, I decided to switch to Verizon and sell the phone. The person who bought it says the IMEI does not match what was on the box, but the phone is working fine. Is there a way they can change the IMEI manually back to what it should be? I really don't want them to have any issues, nor do I know how something like this could have changed :\.
Any help would be appreciated.

The original Imei was probably reported as being bad, so the individual probably had gotten someone to change the Imei

[Q] IMEI 0 but Network is Live

Hey Guys!
Yesterday I bought an LG G3 D855 32/3 from second hand.
It's already running a Custom Rom I don't ask to restore it couse I'll bump the bl right after the buy.
Today I check some thing and I see my IMEI is 0.
But I have a network conenction. Gsm, 2G, 3G and 4G too.
What does this imei 0 means for me?
This is for the custom rom?
Can I backup this efs ?
Can I loss my network If I switch rom?
Regards!

This happened to me on my d851. Unfortunately the IMEI is corrupt, but I was able to recover. After that, I made sure to back up my EFS. If you google "lost imei lg g3" you can find info on the recovery process with a little reading. Anyway I'd make sure you have the original IMEI still under the battery before proceeding. You also might want to check the IMEI to verify it is clean.
Do note, though, methods of writing the IMEI or supporting such are allowed on xda, though.
To answer your question on ROMs. When I had a 0 imei, I was able to connect to providers (att / tmobile) on multiple roms including stock. So in my case, it was just a nagging knowing it was 0. No ill effects. Your experience might be different, though.

It's only a problem if you resell. You have two options.
1) Contact LG and tell them what happened was a bad flash and hope they will allow you to send it in to get fixed.
2) Do it yourself, as I did. This cannot be discussed on xda because it could be used to change an IMEI to one not assigned to your phone. I ill say it's possible and using the software required is a legal grey area, but I technically DID sign an NDA with Qualcomm during the time I fixed my phone. Work reasons, so it may not have covered it, but still. Also there seems to be one version of the stock ROM that works with the software. for D851s that is.
Edit: The problem is the EFS got corrupt. If you fix this by all means BACK UP YOUR EFS and store it 100000 places

Very good advice indeed!
Had this problem with my G2 once

But as i have read in the past, replacing your imei with one that doesnt belong to ur device should cause a hardbrick. Also, i dont live in the US, i bought the D851 from a phone market i think it has been refurbished.
THis could mean that the imei at the back of the device might not belong to this device (I dont really know... at least, thats what friend suggested.) I checked IMEI.info for the imei at the back and it turned out with a no results. Then i checked it on the T-Mobile site and T-Mobile said the device has some bills and if the bills are not paid, it wont be able to be used with T-Mo.(I dont really care as we dont have T-Mo here. But atleast T-Mo recognizes the imei.) THen i checked the imei with one more imei database and it showed up.
Now, my problem is that i know of Qualcoms Program that allows the IMEI to get reassigned but i was wondering that was for devices that are not able to connect to network at all. With mine it seems the IMEI is there. Its just that the OS is unable to read it. Dont you u think using the Qualcomm process would be a little harsh?
Also since its able to connect to network, i think my ISP is able to read my IMEI. Could i call them and ask them to tell me my imei? So that i could compare it with what is written at the back of the g3?
EDIT: I just got off the phone and the ISP/Mobile Network agent said they are unable to see IMEIs from their end.(Not just mine but everyones). I dont know, maybe she just might not know how its done. I will still keep trying tho.

Restoring using Qualcomm software IS hard, overkill and VERY RISKY. At the moment since your provider doesn't care, I say ignore it. Also I have no idea what would happen if you tried to change an IMEI to one not meant for your device as I've not ever attempted such. You phone sounds like it has a bad IMEI, but that would only as you said blacklist it on TMO. The IMEI afaik is only used to track stolen phones and deadbeats on bills. So as the saying goes "If it ain't broke don't fix it". If I were you, I would question the person you got it from about the bill delinquency, but you don't really have to. Just seems fishy to me.
