[Q] LG-P930-V11a Stock Optimus LTE Bell Canada

Hello, i just got my phone in after sending it in for repair, and they upgraded my phone to V11a. This might be the newest firmware, and it seems to fix the battery issues (i have gotten a full day (8am-12:36am right now am at 30%) compared to having to charge my phone mid-day, and overnight).
Here is my story: My phone was rooted before i sent my phone away for repair (and i had cyanogenmod installed) but now it is stock. I remember a need for stock firmware previously, because all we had was a Korean firmware or something like that. Also, because it is a new firmware i am wondering if anyone would like to have it (though i am sure you can just do an OTA update) so i can upload mine if you want. I just don't know how to get the files, and what files to get.
The files i am talking about include the .img files and the .kdz (if i am right) so: baseband.img, firmware.img...etc.
If nobody has or will have a need for these files then i will stop posting about it, but i have a stock (not even rooted yet) phone and i want to do something to benefit the community...
here is some info you might already know:
Lg Optimus 4G LTE

same phone as Nitro HD
Stock - LG-P930-V11a-NOV-04-2011
I will be rooting and installing a firmware by Tuesday if possible.

First,it's very old from and if you want cwm, you need root(not remember if it's possible) or use unbrick instruction

if i make a nandroid backup, and then i install a custom firmware, will i be able to go back to stock, with just the nandroid backup?
I'm asking this not only so i can help myself in case i need to, but also to help other people who want/need to go back to stock (to upgrade/get repairs)
another, kind of related question. how would i get the things like the boot.img, baseband.img, firmware.img...etc. that seem to be needed to unbrick? from what i am reading (i never followed the instructions in the unbrick post though, as i don't feel the need to yet) we only have a korean version of the phone backed up like this. while i still have a stock phone, would there be any way to get these required files. or am i missing the point, and these files are not needed?
Sorry about all the questions, i'm new-ish to this, we all have to start somewhere.
Thanks

[Q] First timer with restoring Rogers GS3 to factory but keep unlocked

Hey there!
So here's my situation: I recently got rid of a Rogers cellphone plan and decided to sell my GS3. Someone I know, immediately showed interest and decided to buy it from me. Good! At that moment, the device was locked to Rogers and was running stock Samsung GS3 (SGH-i747M) firmware.
That person decided to play with the phone, try to root it, flash Cyanogenmod or whatever it may be, and having failed several times, he decided to return the phone and get his money back. I shouldn't have accepted to reimburse him knowing how much he fiddled with it but I did.
Anyways too late now. The good thing is that I believe the phone is 100% functional (it boots, runs perfect and under system info shows everything as usual except under Status > Device Status, it shows modified.
I am not 100% sure of that what means but I believe it has something to do with a modified ROM or something like that.
That person supposedly unlocked the device because he was with another carrier.
Now I am putting the phone in the classifieds. Obviously I would like to have the phone back to 100% factory settings and ROM, no aftermarket stuff whatsoever BUT I'd like to keep it unlocked (if that's possible).
That way, it will be easier to resell.
So here's my questions:
What does "Device Status: Modified" really means?
How can I find out if the phone has been altered in any ways?
If it has been altered, is there a LINUX based procedure to restore EVERYTHING back to factory?
If I restore whatever has to be restored, will it re-lock the device?
As you can see, I am a total noob in that field. I would appreciate if someone can help me to prepare this device to be resold.
I don't want to cause any problems to anyone, that wouldn't be fair.
I appreciate. Thanks!!!

Okay a lot of questions, you can download the stock firmware from Samsung updates and if it is rooted you can get triangle away on the play store and reset the counter the using kies or the Samsung galaxy s3 toolkit from mskip's to flash the original firmware, your phone should be unlocked as none of the procedures should/could reloj the simple card

Ok I have verified with an app called Root Checker Basic, and it said that the device wasn't rooted. I wonder if this is reliable.
I wiull check mskip's toolkit or Kies to restore the stock firmware.
What a pain..
Thanks jimchee for replying!!

Actually it's pretty easy but you can probably sell it just as easy if it's rooted and that way you can clear the counter, there is also a post in the Samsung sIII THREAD for AT&T that will walk you through restoring to stock, just make sure you download the file for your device the link is also in the att thread, if you have any trouble pm me and I can help, I am just a tinkerer but been doing it since my 1st original Motorola Droid

Probably the easiest approach would be to look for the Samsung S3 V7.0 toolkit post. This is a flash (programming) tool. It would easily root your phone if it needs that. Then you can use the app referred to earlier to reset the phone to an "unmodified" status.
Then finally go to the Samsung updates site as suggested and flash the phone with a stock Rogers firmware. I'd recommend a 4.1.1. version. Probably your phone will still be unlocked at this point. But if not, the stock v 4.1.1. Rogers firmware will allow you to unlock it again from an onscreen menu (search for "S3 unlock code *#197328640#"). And your phone will report an unmodified status at the end.

Once the phone is unlocked it will stay that way whether you go back to stock or not.

[D850] Lollipop Update not found - Unlocked Phone

Hi,
I bought a LG G3 from Ebay which was blocked on AT&T for using it both in the USA and in Europe (I choose this model for its frequencies supported). It is a D850 model as you can expect.
After receiving it, I unlocked it to run different carriers. I rooted it as well.
I want to install the AT&T 5.0.1 update from OTA (I don't care about root right know). But I have one big problem. I keeps saying that my software is up to date which is wrong. Is it because I'm on T-Mobile right know and AT&T blocks the update ?!
I'm using build D85010d. right know and I never had a software update notification. I've tried to set my phone date to a couple days forward as suggested by Android Police. No luck.
I just want to have the update. After that if it says "you are rooted, you can't install", I will unroot it and reinstall.
Is there any way to update manually ? I heard it's impossible thanks to AT&T.
This is beginning to irritate me.
Thank you in advance

have you found any solutions to this? i'm using an unlocked att G3 as well (although not blocked) and I can't figure out how to update. i even tried to put someone's ATT sim in it and it still said it was up to date, which is completely false. god i hate att. can't update, can't use Qi charging, can't do anything.

I can't update my lg g3(d855) too. It's have the 4.4.2 kitkat and i want upgrade it to 5.0.1 lollipop.
Plzz help if u find a solution to this problem

Same issue .......how to update to lollipop manually ....................... if someone can help it will be appreciated :good:

I am having an issue with the AT&T Lollipop update, as well. I bought a D850 from eBay on KitKat 4.4.2, and when I inserted my AT&T MVNO SIM and checked for updates, it found the Lollipop update. It started downloading, but about 2/3 of the way through, the display shut off (I had it set for 15 minutes). When I got the display back, this action had stopped the download, and it did not continue. Now, when I check for updates, it just says I have the current version. I have run system resets, and tried a different AT&T SIM, but I can't get the Lollipop download again. Does the start of a FOTA download set a flag somewhere that prevents re-downloading?

Only thing I could think of is asking for a .kdz file for your phone and carrier and then flashing that using the LG Flash Tool

unable to update D850
I have the same issue. I have a D850 AT&T version and my is not showing any update available. I am in 4.4.2. Any solution how to update? Please help. Thanks to all

I'm another victim of this. Have someone found a solution? I'm desperated. And sad, I feel scammed.

Hi, I'm New in the XDA forum.
My name is Neeraj
And when I saw your post, I found me.
What ever you do please don't do custom rom update.i found that in a hard way.
Like you I too bought one from ebay, at&t logo but unlocked, and while trying to update says it's up to date.
Later I found out I need at&t SIM to update the phone. Because it's only network unlocked not the entire phone. It still got some sorts of at&t restrictions.
Any way I went and rooted, installed twrp, and cm13 6.0.1 then Walla my phone goes into reboot loop and when it finally opens up the network doesn't work.
By the I'm in Australia , temporary residence and I don't have at&t SIM.
So good luck and infact i'm hoping some one will guide me too

I fixed it, don't know exactly if it will work on others.
But what exactly I did was search Google download official stock rom for at&t LG G3 D 850 ( KitKat or lollipop), flash the rom and Walla got my IMEI number restored and it fixed my boot loop problem.
Then backed up by all data, IMEI, etc and then flashes back to custom CM marshmallow. Now all is well. ?
Hope it this will help some one aleast a newbie lie me

New Nexus Owner Seeking Advice

Hi folks! Just received a 2013 Nexus 7 from my fiancé as a birthday gift. I wanted it for quite specific purposes so was hoping I could ask a few questions here and get pointed in the right direction before I start using this thing
I intend to mainly use the tablet for remote play with my PS4 and emulating old console games. Since I want to connect a PS4 controller to it wirelessly I'm told I need to root the device. I'm guessing this is an easy process and there are some guides on the site here?
The main thing I was after advice about is firmware updates. The system came on 4.3 and has already downloaded an update for 4.4.2 but I haven't installed that yet. Is this firmware fine to upgrade to? Any performance issues? I've heard people saying that upgrading their Nexus to 5+ (Lollipop?) has created a load of performance issues and this should be avoided? Also, if I upgrade to a certain firmware version can I lock myself out of being able to root the device? I'm pretty sure all of the apps I was planning on using work no 4.3 so I have no reason to upgrade at all but if I can go safely to a higher firmware that is reliable with no performance issues I may as well?
First time using an Android device so sorry if my questions come off as a little stupid. Also, wasn't sure if I should post this here or if it should be on the Q&A board so sorry if I've got that wrong!

As far as I know, the problems with lollipop were the standard number of complaints that come with any new release. Well, I'm not really positive, but lollipop seems fine to me and I think most people have upgraded by now. I would go for it because I think it's really fun to use.... Plus you can always revert if you choose.
As far as rooting, you never need to worry about not being able to do it... Rooting your Nexus 7 will always be easy. The by-hand method is fun and relatively simple, or you can just use the toolkit in the forum to do it even easier.

^Yeah I'll echo that. Lollipop is good. The people having problems don't know what they're doing. Flash the factory image.
If you want root you can use cfautoroot or simply flash twrp with fastboot then flash the su.zip

Personally, I'd stick go for 4.4.4, as 5, 5.0.1 & 5.0.2 all have a memory leak issue. You may also find more emulator compatability as Kit Kat has been around a year longer than Lollipop. The only downside to KK over L is the battery life is a little worse IMO.
I dont think the memory leak issue is a result of someone not knowing what they are doing etc.

Thanks for all the advice everyone

I'm fairly competent with computers (as I should be with a degree in computer science!) but this is all like a foreign language to me. I guess I'm better sticking with the toolkit for now until I'm familiar with all the lingo?

Thanks. This is the sort of advice I was after and is why I mentioned what I was planning on using it for. The device has already downloaded 4.4.2 and wants to update to that. Is there a way I can manually go to 4.4.4? I'm worried it will just request an update from the Google server and try to jump straight to a version of 5

If you unlock the bootloader then familiarise yourself with ADB and flashing factory images, you can manually flash any version of Android (That has been availible for your device,) manually. You dont need to be rooted to do this.
It also allows you to go back when you've made the mistake of updating, (but does wipe all of your data!)

It ended up offering me the updates incrementally anyway. I went from 4.3 > 4.4.2 > 4.4.3 > 4.4.4 which I'm currently on and will leave it there for now. It's downloaded 5.0.2 but I've skipped the install for the time being
Think I need to do a little reading up before I root the device as I haven't got a clue what some of you are talking about haha. Thanks for all the advice so far though

No problems.
I've had a few Nexus devices and never felt the need to root them. :angel:

The majority of problems stem from Qualcomms crappy broken mess Adreno gpu drivers, hence the delayed
rollouts of Android for the Nexus 4 and 7 that both use the Adreno 320, don't be suprised if the Nexus 4 and 7 get a
Android 5.1.1 release instead.

For ppl new to nexus devices, wugfresh nexus root toolkit is a great tool until you get the hang of adb and fastboot. With a nexus you can always switch between android versions. You can always root, or go back to older versions of android. Updating to newer versions never hurts anything because you can always go back. Its a developers device so its very versatile. Try lollipop if you like, (I love it) and if its not your thing, just flash back to 4.4.4. I love this tablet.

You for got to mention the disclaimer if your tab came with 5.x.x out of box you cant go back to KK. Also a lot of us who recently bought Nexus 7, I have 3 that I have acquired, came with 5.0.1 installed are having issues with partitions/memory mounting in recovery. Some sort of revision done in the latest batch sent out. If his tab came with 5.0.1 or higher and has his bootloader at FLO 4.04 he may have problems trying to go back with either bootloops and what not.

[Q] Updating an unlocked LG G4. No rooting.

I have the LG G4 H812 (Canadian model). Bought from Bell and unlocked to use with Koodo (they don't have the G4) I read somewhere you can update an unlocked phone (because you update over WIFI) then I read that you CAN'T. That you have to root it and build an OS/ROM. I am not prepared to do that because I'm pretty certain I would ruin the phone. I'm terrified to even try. Rooting might be ok but building a OS/ROM? Forget it! I mean WHY do I want to build an OS? I just want to be able to update my phone! Not go through a bunch of crap. But no somebody said you HAVE TO build it...
So can I get android updates on my phone or not? It's running 5.1.
Watching this video. Would this happen with an android phone? youtubeDOTcom/watch?v=o8gGb2lqJjE
And PLEASE no "GO away newb. This is for developers only la la la". I'm asking here because I can't get a straight forward answer anywhere. I spent almost $800 on this phone and I want to be able to update it without it getting ruined in the process. Or else I will have to return it. I don't want to because there are no other phones I even remotely like.

Not sure what you mean with update. If you mean updates from LG, sure no problem. My unlocked G4 (H815, asian model) on AT&T was updated this morning, using wifi. Root not necessary.

I would assume that since you are just unlocked in the carrier sense and not Root/Bootloader unlocked that this should not be an issue.....I mean I have never heard of this causing a problem before now.
I will try to look around and find out a concrete answer for you though as like you said, would hate to have something negative happen to that wonderful (and expensive) device.

Updates won't be a problem. I bought a G3 from Rogers because Telus didn't carry the LG Line. I immediately sim unlocked it so I could run it on the Telus network. Received the lollipop update with no issues.
