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

TL;DR
I have stock firmware, and i am wondering how to make a backup of the firmware in case i need to restore to stock after i root and install cyanogenmod.

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
Hello guys! I have been using this forum for a few years now but today i had a frustration and i want an expert guy to help me out
I try to understand the differences between baseband, modem etc. What they are and what they do!
I have an LG G2 D802. Until now I used KK ROM GloudyG3 2.1. I decided to install blisspop today which needed first to install bootstack (what is this?!). I think is related to bootloader. Anyway. I did the procedure and the rom indeed was installed and booted ok. There was a problem with the signal reception though! WiFi was working.
Since I had a problem I had to return to CloudyG2 using a backup I made. I also had to install kitkat modem since i was stacked in LGs boot logo on the first restore try. Beofre today, I thought that I undestand various things on how this ROM thing works. Now with KK, LP etc I'm totally lost. Can someone guide me?
Hi guys and girls i am from the uk (england) and got my g4 about 4 months ago.
Fed up of lg's stock rom and how its very laggy and irritating to use now.
I have been looking everywhere about rooting the phone and installing custom roms to make it much better and more enjoyable to use.
But i am stuck i dont know whats the best way of rooting this phone i have tried booting it into stock recovery mode but it just dont work.
so can you guys please point me to a right good method of rooting and installing custom roms please?
Currently using android 5.1 on lg stock rom
Many thanks!

Have you unlocked your bootloader ?
No not too sure how to do that. Any good threads you guys reccomend.
Many thanks
So I know this is scary for you and because it is something new, therefore be sure that you want to live with the responsability if something goes wrong.
Now, the next forum thread tells you how to flash an already rooted image BUT, and this is very important, this works only if you have the version 10c installed (Check in About Phone>Software Version)
http://forum.xda-developers.com/g4/orig-development/root-tmo-vzw-intl-variants-soon-root-lg-t3164765
If you have the latest version of the software (20a) the best thing is to unlock your bootloader, void your warranty in the process, and flash a custom recovery. After that, you just need to flash the SuperSu zip file and you will have root.
To flash custom ROMs, just access recovery and flash the zip file of your ROM.
I'm using the unofficial CM13.0 and works very good for me, but I do miss the official camera app.
Thankyou very much for your advice okarr. Will look into this
Hello. I have d855 android 5.0 . Wanted to install cm 13. and here are my steps:
1. Rooted my 5.0 , flashed TWRP, and flashed CM13 and gapps. There was a problems with dialer after flash, so i downgraded phone into 4.4.2 V10a (using .tot and .dll files) . .
2. Again tried to flash CM13, but process was aborted and phone bricked.
3. Flashed stock 4.4.2 again. Again no luck to write CM .
4. Flashed stock 5.0 v21a using lg flashtool. Again - if i want to flash CM - phone always bricked (error executing updater binary) . And now, even with stock 5.0 my phone data connection do not work (only wifi works)
Please help .... how to reflash my phone and get CM and back data connection??
Just tried flash 4.4.2 again. Flashed successfully, but still any data connection Tried update into 5.0 using phone software updater, but after few updaters it fails (invalid software package).
Today found, that data connection works perfectly if i set GSM/WCDMA . If LTE is selected, there are no data connection at all. Also, can't flash custom rom, phone always stuck at LG logo. Anybody can help so solve my problems?

I want to cite only the first point you described, because it's "abominable"!
Sorry for the harsh tones, but... the dialer issues obviously involved the Cyanogen rom, especially because you're using the first nightlies, often unstable.
Why you accused the official firmware (therefore no more existing since you replaced them) and decided to downgrade?
Then you've to known that important downgrades like Lollilop > KitKat may irreversibly corrupt system partitions like "efs", which make your device losing of IMEI code and mobile data!
Now the only thing you can do is updating your device by settings menu until you reach latest firmware (21A).
Since you've to manually confirm each updates (10A, 10E, 20A etc.), the process will take almost 1-2 hour.
When the update process in definitely completed, you can try to root device, install TWRP and flash latest CM13 nightly.
In case of other issues, try the quite stable CM 12.1, or the stock-based FulmicsRom.
If you continue to have troubles, do a CSE flash of 21A firmware and send your device to warranty.

Last time I connected my phone to LG mobile support, and it automaticallly updated my phone into newest official 21A firmware. IMEI - OK, data connection - still do not work when LTE is selected. So what i need to do now ? Try to root, install TWRP and flash CM 12.1 or FulmicsRom ?

So what's your problem when LTE is enabled?
Mobile data won't work or simply fallback to HDSPA?

When LTE is enabled, then there are no data connection at all.

Surely downgrading the entire firmware to the first release of KitKat broke the radio part of your device.
Probably if you downgraded to latest KitKat firmware (10h maybe, instead of 10a), LTE should works properly.
Have you encountered that connectivity issue even before flashing CM 13 (on official firmware)?

No, after flashing everything was fine. There is a way to reflash radio part without downgrading again ? Because when i spoted that data connection do not working, i downgraded firstly to 10a (no data connection), then i get 10h update - still no data connection. And after 10h update, my phone got another update, but showed that can't update because package is wrong of something. After that i flashed 21A what i have in my phone now.

Probably the mobile data issue was related to CM 13.
But when you downgraded to 10A, the radio part was really damaged.
As I said if you want to downgrade, always preger the "less old" firmware you need.
Like you, I downgraded in past to KitKat, but I never looked for 10A! I directly flashed 10H.
Sorry, but at this point I don't know what you have to do.
When you flashed 21A firmware, have you done a CSE flash instead of a normal one?
If not, do it.
If yes, you have to appeal to warranty without any problem, since your device has official firmware.

Yes, i did CSE flash. Ok, thank you. I think there are no more options than warranty.
I'm tired of the problems and struggle I've had attempting to use my rooted G4. I'm currently on 13b rooted and it's been giving me problems. It randomly reboots and doesn't start up at times. And it's so sluggish. I've gotten a replacement because I flashed the wrong kdz. I just want my phone to work without all these problems. I just want to get to the stock Verizon MM for my G4. Is this possible?
You should be able to flash the MM kdz - they can be found here in the general section. Be sure to verify it is the correct kdz.
Keep in mind once you go to MM you won't be able to achieve root without downgrading back to LP. I think there is a downgrade thread here in general as well if you need it.

Thank you I just downloaded the KDZ and flashed via LG UP. It installed without any problems. I'm aware that you can't root on MM, I'm ok with that. I need a break from rooting after all of this. Thank you I appreciate it!
Glad to see someone here not happy with rooting the G4. I don't find it worth the risk or the benefits worth it without the ability to flash custom roms. I've never rooted a phone without there being a way to install a custom recovery.
For anyone interested, The Android Central podcast discussed the topic of rooting and flashing roms a bit on their most recent episode. Most of them agreed that there isn't as much of a need anymore to root and flash roms and that it's kind of died down a bit. Features that people used to have to root their phones for are now available on most stock roms.

how to install LGUP tool
https://www.youtube.com/watch?v=igB5rnLRXSc&spfreload=10
i know at the end of the video it says close the app, but dont, just start it and you be upgraded to MM in no time just make sure upgrade is checked
if you want to start fresh, then you can just do what my video says to get refurbished checked
if you upgrade with a rooted rom you have to factory reset your phone inorder for MM to boot
