[Q] Original firmware restore and E977 compatibility - LG Optimus G (International)

Hi All!
I'm about to buy this phone, but I think the original android interface will be better for me, so I intend to test some roms.
I never had a LG Android phone before, only Samsung, and I used to use Odin software to restore original firmware on the phone.
Before I buy it, will be good to know if I can restore the original firmware if something goes wrong while trying other roms. Is it easy? even on a softbricked phone?
I'm in Brazil, so the model is E977 with different modem driver, because of the LTE band. I read at one rom specification (avatar if I remember well) that it don't touch the modem, but I need to know if this logic applies to all roms, and how can I change the modem driver if needed.
Thank you in advance

Fast and easy...
YES to all!
About your last question, download e flash the modem patche.

flashing original rom LG GW620

Hi I flashed the custom 2.1 ROM, but since there's a lot of stuff that doesn't work. So I want to flash back to the original rom. But how do I do this. I can't find the original ROM to flash the phone.
I tried the tool from LG but it stops at 4% flashing and then it tells me that the connection has to be reinitiated. But it just keeps saying that.
Any Ideas would be gratefull

Totally agree, I need to restore the stock rom. I don't know why there is no category for LG GW620 too

as i've understood the problem is that after upgrading to android 2.x we can't go back to our original firmware 1.5 and that is due to a conflict between the two baseband...anyway there is a rom that can allow us to come back to android 1.5 and it is called ToleRom0.8

[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
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.

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

new to lg g3 questions

hi guys im new to the lg g3 (well any lg phone) just a couple of questions
from what ive read there isnt many roms due to the locked bootloader will the bootloader be unlocked in the future?
i have the D855 uk vodafone model is they a working TWRP or CWR for the g3?
ive rooted so does this mean i can at least remove some bloteware?
thanks guys sorry for questions :victory:
from what ive read there isnt many roms due to the locked bootloader will the bootloader be unlocked in the future?
Probably yes, if the @thecubed and others beat the protection (last post - http://forum.xda-developers.com/ver...3-vs98510b-t2890349/post55729952#post55729952)
i have the D855 uk vodafone model is they a working TWRP or CWR for the g3?
There is only Tethered version and I would not recommend to use it. It's for advanced users only and it's not a "real" recovery. More on http://forum.xda-developers.com/lg-g3/general/recovery-twrp-2-7-1-3-t2831668
ive rooted so does this mean i can at least remove some bloteware?
Yes, you can... , or freeze it. If you will the cause softbrick, use LG Flash Tool 2014 and flash in NORMAL mode latest stock ROM you used or use LG PC Suite. After this you need to re-root it. (http://forum.xda-developers.com/lg-g3/general/guide-unroot-ota-using-lg-pc-suite-pc-t2802286)

thanks for the replys if the bootloader doesnt get unlocked then thats going to destroy the g3 for development isnt it
is they a way to flash latest stock rom and get off the vodafone branded rom so i at least get all the latest OTAs?
Not sure I understand you question, but if you mean, whether you will be able to update the phone via OTA in the future, it depends.
If not or if it will not work, unroot your phone, install OTA and the re-root and you should be fine.
But still - all of that is already described in dedicated threads, don't be afraid to take a look around. :fingers-crossed:
As for the development - I guess when it will not get unlocked, it will be from my perspective one of the most wasted money on Android phone for many.

lol sorry what i ment is im on a vodafone branded firmware now and i wanted to flash a unbranded latest uk stock rom so it will be first to get OTA as branded firmwares can be a bit behind is it possible?
thanks again:good:
I don't think so, but someone else should confirm it.
Eg. you can download FW based on IMEI (http://lg-firmware-rom.com/download-firmware.php?f=YOUR_IMEI_HERE), not based on whether it's branded or not.
But still you have option to use the tools like LG Flash Tool 2014 and simply flash latest firmware you want (for your variant)

I know its confusing but you can only flash TOT files with that tool - if you get your FW via the imei cause its a KDZ, for KDZ flashing you need to use this tool...

HELP! T-Mobile G3 - Can't Upgrade to Lollipop Via OTA or LGMobile Support Tool

Hi everyone! I need some help or guidance here. I think I may know why this is happening but not sure . I'll explain in detail below:
Anyway, so the long awaited Lollipop was apparently released on April 7th for the T-Mobile LG G3. I've been waiting for it for a while just as many other probably have been. Well, none of the updates ever showed up on my phone via OTA or the LGMobile Support Tool.
The only thing I can think of as to why this MIGHT be happening to me (unless nobody else has been able to update yet because T-Mobile delayed the update) is because my IMEI has been reflashed to a Galaxy Note 2. However, I'm not sure that a different IMEI on my phone would prevent it from being updated since the firmware is obviously still a D851 LG firmware...
My phone is NOT rooted. It's all stock by the way.
Anyway, I guess what I need to know is:
1) Has everyone else with the T-Mobile Lg G3 been able to successfully update to Lollipop yet?
2) Will the different IMEI on my phone affect whether or not my phone is detectable as a D851 G3?
Thanks everyone in advance!
Bump. Anybody?
I'm really not sure that IMEI have any effect on the update center , have you tried to do a factory reset ?
another thing I can think of is just root your device and install a stable fast stock rom that uses LP on it ( like cloudy ).

Yeah I'm not sure it does either. I talked to a friend of mine that works at T-Mobile and he said a mismatched IMEI shouldn't make a difference. However, worst case scenario I'll have to manually flash it to Lollipo once the official ROM has been uploaded somewhere on the internet. I haven't tried to do a factory reset. Not positive on this but I think the IMEI is stored in memory that won't change whether it's factory reset or not especially since the original one was wiped and replaced.
I'll try to stick to the stock ROMs on this phone to avoid any issues with the custom stuff. Although, I was never able to successfully tether via WiFi on this phone. It works via USB cable. Still annoying hehe.

There is already a firmware on the forum: http://forum.xda-developers.com/showthread.php?t=2785089
I don't know if you can do this guide though since you never rooted your phone, better if you ask there.

Thanks for the link. I don't think the OP has the D851 Lollipo version uploaded. I only saw it for D855. I guess I'll just wait until everyone else gets the official update and flash it manually. From what it sounds like people have been having issues minor issues with Lollipop anyway. Maybe that's why T-Mobile is delaying the OTA updates. Who knows

[Q] S3's Model Number changed after installing wrong ROM

I have an SGH-1747M which I am sure is the correct model since that it is what it said before I installed a new ROM and it is the model listed at the back of the phone, with the serial number. Recently, I installed a Lollipop ROM from this thread:
http://forum.xda-developers.com/galaxy-s3-sprint/development/rom-d2spr-cyanogenmod-12-1-t3074688
The ROM was meant for for the model SPH-L710, but it managed to be installed on my SGH-1747M phone. The ROM, although it works perfectly, has changed the model number on my phone to SPH-L710, and now my phone is only compatible with d2spr. I tried installing the ROM actually meant for my phone but I was unable to since my phone isn't d2att (the actual code for my phone) anymore. I tried installing a stock ROM through odin but it still won't recognize my phone as SGH-1747M.
I need to know how I can return back to my default model, since I have been told I will have network problems with the current ROM since it is not meant for my phone.

Visit this thread but don't flash anything else until you have read and asked for help there . Post there and explain your situation and even private message the op if you need to . http://forum.xda-developers.com/showthread.php?t=2363882
I would just be extremely careful with this. Do you make a nandroid backup before flashing? I would restore that or a previous one first. That will probably fix your problem.
Have you tried to flash one of the Unified CM 11 Zips? Those are kind of universal installer, see if that will fix your problem. http://download.cyanogenmod.org/?device=d2lte Download this and make sure you wipe everything a few times. Then install the zip.
People on here bricked devices by downgrading to certain modems/basebands after flasher a newer one. It seems like you have a newer modem, so I wouldn't try it. If you can still get into download mode, I would flash the latest tar for your device. I'm pretty sure it is an AT&T device or close variant.
