Anyone verify if that LG IMEI backup app worked the same way? I flashed the zip with flashify and it worked fine.

I made a restore before flashig a rom, then I found out that my IMEI numbers where 0 and no signal. Now im trying to restore but after restore it just boots up in TWRP again. I flashed the zip file and restored again... did not help. Am I doing it wrong?

Backup Verification?
Is this all you need for EFS restore on the G3? I used the manual method through cmd terminal/adb on my pc and successfully created the two files. Can someone explain to a noob how I can verify that it was successful, i.e. a way to check the two .img files that were generated? Thanks in advance.

How to check if EFS is still on my device?
Hi guys, I'm an owner of a new LG G3.
Now I have a problem. I went to TWRP, deleted EVERYTHING in the wipe menu, without backing up EFS. Then I installed ChupaChups 2. with the ChupaChups skin and SuperSU 2.37. Now I don't know if I lost EFS or how to check if it's still on the device. Because in the settingsmenu "about phone" I can still see my IMEI and data seems to work fine, at least on 2/3g. Can somebody tell me how to check on this?
Someting odd at last, I experience Bluetooth-hickups with the rom, anybody can confirm this?
Thank you so much for your help, I'm a bit desperate here because I don't know if I really just destroyed my phone and I am hoping I'm able to restore to stock.

what are my options if I mess up my NV files and I don't have EFS backup

Looking for assistance with missing efs info for Verizon lg g3. I am technical enough to do it with steps.

difficult situation
Hello,
It depends what you have in mind when you say "my info". If it is precious personal data, and you don't have a copy on another media, this is not too good. :-/ . If it is about the operating system and it's features, I have read that flashing back to stock rom is possible, as LG provides them in their Open Source section.
/Edit: ddaypunk06 I can't answer to the new content of your post. Someone else will.

I am interested in making a back up of my EFS folder, but I'm not rooted. I read here :http://forum.xda-developers.com/lg-g3/development/efs-lg-g3-efs-backup-restore-t2907329 that it can also be done using 4 ADB commands. Is it still necessary to be rooted to use the ADB commands ? by the way I'm on V20f.

Hi,
As I understand things, the 4 ADB commands mentioned are meant to root the phone. From this part of this post:
http://forum.xda-developers.com/lg-g3/development/root-root-lg-g3-easily-purpledrake-lite-t2821000
But, what if I don't want to run your script to root?
Well then, I'd be a little hurt, but you can still do everything the script does manually.
Download the package, and extract it. Open a terminal in the main folder of the archive and run these commands:
Code:
adb reboot --bnr_recovery
adb push ./assets/start_restore /temp/start_restore
adb push ./assets/permaroot.bin /temp/start_restore
adb reboot
That will perma-root you, however there's no protection from doing something stupid or the phone being incompatible. Please be careful!
Click to expand...
Click to collapse
So be it with 4 ADB commands or with the help of the DrakePurple-Lite script, you need to be root in the filesystem of your phone, if you want to be able to perform administration tasks.
So how I understand things, you can't access to the said files: the 2 parts of the bootloader, if you are not root in the Android operating system. Please see here:
http://forum.xda-developers.com/showpost.php?p=54254062&postcount=2
EFS Backup:
Backup EFS after jailbreaking your G3. EFS is split into 2 partitions modemst1 and modemst2.
img files will be on root of internal sdcard. Save the .img files somewhere else besides the sdcard... email, cloud, etc..
I have made a new thread on EFS backup and restore which can be found HERE.

Hi there.
Go to Settings>about phone>Status.
You should see your IMEI, MAC Address and operator connection.
Also go to Phone and dial *#06# and you should again see your IMEI.
Make sure that it is not all 000000000s.
Edit: If you play with flashing roms backup your EFS folder!

Thanks for your reply. In conclusion , since we can't root lollipop yet, the only way to make a back up of my EFS folder is to downgrade to kitkat, then upgrade to lollipop. I'll think about it.

I only have a 4.4.2, LG G3 S stock, untouched, not updated. I am waiting for a missing clue to root it using DrakePurple-Lite in my Linux distribution. Which codename does that one have? With all the new words I am learning these days, I start getting into confusion, and "KitKat" and "Lollipop" looks to me like lots of sugar. I'll try to keep my phone on a low diet. lol

Can't find EFS folder
Hi!
Today I flashed EFS Backup but I can't see in windows or in the phone with root explorer..etc. But I see in the Recovery..So i can't copy to my computer or anywhere else..
Can You help me?
Thanks

I'm sorry for pulling the noob card. I have managed to backup my EFS using TWRP. I would like a second type of backup to be sure before I move any further. I've been down the lost IMEI on my Note 2. So my new G3 is a VS985 and this method does not seem to work? It goes through all of the steps, but when I look for the created folder there is nothing. Even the folder does not exist. One thing I have noticed is that when I try to create a backup from TWRP to the internal storage the same behavior occurs. Something is written and even TWRP can find it. Although when I am looking around for the created folder... I find nothing. Although when I write a backup to the SDcard it can be found. So if someone could help me with this it would be great. Thank you all for your time.
I think this is the same issue as the poster above me.

I get the impression this thread is no longer active?

Another utility to use for backup and flashing back would be the bkerler edl python utilities.
Search for it and you'll find his github page, and on it, he even provides a bootable image you can flash to a usb drive, boot it and it's ubuntu with all the utilities and all dependencies resolved.
I've used them many times and it's the first thing I do is use them to backup original rom on the device. Sorry, don't have at&t, just sprint.
Keep in mind there are some partitions you NEVER want to flash from someones backup, they contain imei and s/n.

Does anyone have firmware for ATT G8?

So I tried many ways, as an unexperieced rom flasher, and so far had no luck.
The LG G8 ATT phone doenst even want to boot into recovery mode.
Also connected to a PC via USB and entered some commands via ADB tools and even then it will just reboot the phone.
Anyone got a clue what I am doing wrong?

LG G8 sprint "Download mode"

Good afternoon friends. I still have a problem on my phone "your device has failed a routine safety ..." after I locked the bootloader. I gave it unofficial for repair, they could not do anything there. But now, for some reason, my phone does not load in edl9008 mode, but there is dowmload mode as on other lg devices (in theory, it should not be). So the question is, how to flash the phone via download mode to any other firmware? The main thing for me is that it starts and I can return twrp to restore my native firmware. Yesterday I tried it through uppercut, lgup didn't work. Does anyone have any knowledge of how to download kdz to this phone?

Don't think you'll ever see, in your lifetime, a sprint kdz. Nor will you see an at&t one.
It's very important to do some research, initially, before messing with your phone. It's common knowledge that these kdz don't exist, and, that is why we always want to do a full backup of our device, especially when the kdz isn't (nor will ever be) available.
So where are u now? what's the situation? I ask because there are sprint backups around (from individual personal devices), that, if done carefully, can be used to fix a device without messing up the imei and s/n.

V450PM LG V50 Sprint update to system 20N

Hello guys, so after spending a lot of time doing research on which partitions to extract to flash. I found out that the partitions on the link did the trick. I have 2 Sprint V50 same model one is rooted, the other is not, made the backup with Qfil from the non rooted and flashed those onto the rooted, that did the trick. Only use Qfil to flash partitions, do not use TWRP, it'll fail and your data will be erased to get it to work again!
The files are the one's I used, so I upload those to you guys! Hope it helps someone, if you have a doubt, just ask I'll be happy to help.
When I have some time I'll try to make a guide of it. If a new update arrives I'll update this post with the new files!

Strange I've never had any issue with flashing these in TWRP as long as I clear data/userdata. Then again I prefer starting fresh on a new OTA.

What happens when you try to boot download mode? I'm not sure which kdz you are looking for. If it is sprint, I recommend looking for the v50 sprint backup files shared on xda. It isn't kdz, but result should be more or less the same.

Question [Question] Who has rooted TMOBILE 9Pro Stock ROM

I understand I can convert to EU.... However, I don't wish to do that. I just want to root my stock TMOBILE ROM.
My sim is unlocked and I have the unlock.bin from OnePlus for my phone. For anyone who has rooted TMOBILE stock ROM, which boot.img did you patch? I've read that AA boot image can work, but no firsthand accounts confirming this.
Ideally, I'd like to use my own boot.img but I can't find a tutorial or guide anywhere advising how to obtain my boot.img without root.
Thanks!

It is understandable to be freaked out,. But if you follow the direction letter for letter then you should be fine.
Also good rule of thumb is make sure you have all the drivers and software loaded on your pc, then make sure your pc and phone can talk in adb and fastboot before you start to flash your phone.
I have rooted my stock tmo rom with aa and all good. Of course I went even further and installed the EU version on my tmo bought 9Pro..

Yep, confirmed, 9pro and my computer can talk. The whole MSM thing is what is worrying me. In the MSM tool, it says it is the TMO -EU MSM. So, once it does it's thing and flashes it all, it should wipe the phone, it would be on the EU rom?
From there, I would need to follow the steps, unlock BL, flash modems, and then download oxygen updater to be able to locally download updates and install?
