need help no 3G/LTE

I bought an F180L from Hong-Kong. It is a Korean version (U+) LG Optimus G. When I turned on the phone (before I put sim into) offered me to upgrade it. After upgrade there is no 3G/LTE. I have tried almost everything (rooted, unlocked bootloader, installed KDZ, intsalled stock and other ROMs) nothing worked.

I read about backup/restore efs, but I don't have efs backed up, so nothing to restore it. I tried to find old ROM (F180L 10q) to make a backup of efs, but I wasn't able to find any KDZ file to make 3G/LTE working.

I'm not a beginner rooting, unlocking phones but I need a tutorial how to make it working. Luckily I know my IMEI, Baseband, kernel, software version, but nothing else. Is it possible to fix this problem.

Best,

Will this work on the LG Options G Pro E980?
[LG Optimus G (International)] autoprime:
probably not.. but id need a partition list from the optimus pro first to correctly respond.

my efs backup script for the lg optimus g might work instead. btu again.. ill have to see your partition list first.

run the code below in adb shell. paste output in pastebin.. post link here.

[LG Optimus G (International)] autoprime:
ok going to be hard to say without actually seeing the actual partitions... because you have both m9kefs1/2/3 and modemst1/2 . your efs is either m9kefs1/2/3 or modemst1/2... the optimus g used m9kefs1/2/3... the g2/nexus 5 uses modemst1/2.

im going to guess and say lg og pro uses m9kefs1/2/3 tho(same as lgog)...

if not.. then the g2/nexus 5 efs backup would work - http://xdaforums.com/showthread.php?t=2514095

if u wanna run both.. then send me the backup zips it creates.. i could look thru them and give you an exact answer on which one to keep. again.. im leaning towards your efs being in m9kefs1/2/3 tho.. which means this lgog backup method would work.
[LG Optimus G (International)] aatish:
I have actually able to extract my efs modem file using a script which was made for LGOG i got back 3 files one is larger 65Meg file others are 3 mb each approx.

I think you are right that it uses m9kefs1/2/3 though I am not sure what it means :D but can you help me in one thing? I want to flash other stock rom than my own which has less carrier stuff (specially korean U+) and is in english entierly including the dialpad, sms limit and annoying call to korea or local call options!

but i have like tried telcel, claro, panama, hong kong and indian roms on my cell but after flashing the modem i can't seem to get it working. e.g. panama takes the modem i get the signal but when i tried dialing or pickup a call it crashes! :)

I am going back to korean f240L but i really like to leave it!

here is the link to download modem

pls help

buddy, i need some help from you...i have messed up my E970 phone's network.

Actually, i messed up with its EFS parititon and now i am not getting any network in my phone. My phone is ON, everything working but it is not detecting any sim :(

i read on XDA forum and got that i need to replace my EFS paritions again with system actual EFS partition file.

Any user friend who has E970 and who is rooted, pls download below file and run in recovery to back up the phone's EFS parition, then pls mail me that backed up EFS parition file so that i can replace it to run my sim card:

http://dl.xda-developers.com/attach.../8/4/9/9/Optimus_G_Create_Flashable_EFSv4.zip

pls download, its only 1 MB file and it will create a single file of small size (in KBs), that file will be placed in /sd card/ EFS_backup

pls mail me that file to save my phone...pls help ppl...it will not take much of your time...help
[LG Optimus G (International)] autoprime:
no one will be providing you their efs. EFS contains the imei. it would be very unwise to share an imei with someone else.

you didnt make an EFS backup.. so it is no ones fault but your own.

..what happens if your EFS_BACKUPS directory is corrupt or deleted and you've had a system crash? :rolleyes:

Will a full system CWM or TWRP image have anything that can be restored? I have no dedicated EFS backup left it seems, and my IMEI has been wiped. I *do* have some CWM system image backups that were made a few weeks ago and last month prior to installing CM11 updates, or a system image created with TWRP last year- would either of these contain EFS backups? :crying:

Need help getting efs codes/bootloader unlock in on locked device

I have a bit of a circular issue with getting my LG Stylo 2 unlocked. I was going to buy an unlock code with my IMEI so I could switch it to T-Mobile, but now the phone is "permanently locked" to Cricket because my sister entered the wrong unlock code in too many times. I am also locked out of the device in general because I did a hard reset and they wanted the last account info associated with the phone, which I'm not sure if I have access to or not yet. I want to reset the number of attempts on the unlock code back to 0 to bypass the permanent lock and I think I can do that by cloning the IMEI and creating EFS backups then switching the hard-locked EFS with the clone so the IMEI is able to be unlocked and then switch back to original EFS to enforce bypass (or maybe by editing EEP backup file with WinHex and modifying to the phone simply by changing one character from 00E7C to 0AE7C which should reset the count on the lock as if it hadn't ever been tried), but I can't edit anything without a root, and I can't root my phone unless I get the bootloader unlocked, and LG developer won't send that code to my phone model. So now I can't find a way around it without that unlock code, but I have heard that it is possible to unlock the bootloader without LG's help. Any advice on how to go about doing that (while still being locked out of settings and ONLY having access to fastboot mode and accessibility? Or if the stylo can even handle a root in the first place?

I was on LJC, wiped dalvik, cache, and rom, and then installed Synergy r46 WITH modem (there is one with modem and one without modem on the download page). The next day, when r47 was released I dirty flashed on top of r46. My phone has been running flawlessly since (with the ziggy kernal).

You may be able to go straight to r47, but what I posted is exactly what I did and it worked. Hope you figure it out!

[T-Mobile myTouch 4G Slide] Unrelashade:
Hi guys,

I'm trying to find a Android 4 ROM/ Kernel that doesn't randomly reboot my MT4GS. So far no luck with CM 9.1 from scverhagen r8, r9b, r7b and the experimental 10a3, AOKP 4.2, CM 10 has been most stable of all so far but drains battery soo fast and also got me random reboots or shutoffs sometimes... The other ones usually reboot very fast after flashing. About 10 minutes after that, at least if the phone sits idle. Maybe when the phone is going to sleep or deep sleep? (Don't know what that is exactly)

Since these ROMs seem to be very stable with a lot of you guys, maybe I'm doing something wrong? I always wipe and format data and system and wipe battery stats and dalvik cache before flashing and don't use the phone for 7 minutes after rebooting... I have the newest radio I could find in the forums which is Radio 11.59.3504.00_11.16.3504.20_2

As always, your help means a lot to me and is greatly appreciated.
[T-Mobile myTouch 4G Slide] mattlowry:
Are you still-off?
[T-Mobile myTouch 4G Slide] demkantor:
*s-off

mattlowry is getting at if you are s-on be sure to flash appropriate kernel after rom flash, also take a look into what apps you install, some are poorly coded and can lead to results similar as your own
[T-Mobile myTouch 4G Slide] Unrelashade:
Thanks guys! Fastboot says:

That means I did everything right and phone is s-off, right?

And yes demkantor, I know some apps are problematic and cause reboots/ instability, however I recently tested without installing any apps to be absolutely sure, even without gapps and it still crashed/ rebooted.

I am still without a clue, even you guys don't have another idea? Haha I don't get computer stuff even after all these years...

Oh I got another idea. Maybe my battery is broken and because most kernels optimize battery use and undervolting etc, maybe this results in my phone crashing or rebooting? Also, maybe a reboot means a problem with the rom/ kernel and a crash (instant shut down) means higher propability for a battery problem?

Man I'm really desperate hahaha
[T-Mobile myTouch 4G Slide] mattlowry:
Is it only with the experimental kernels or does this happen on stable kernel as well?
[T-Mobile myTouch 4G Slide] demkantor:
Most kernels probably wont have undervolting built it, and yes as your rev soff you dont need to flash the kernel seperate.

Battery could be a culprit but not a common cause, maybe pull a last_kmsg next time it happens
[T-Mobile myTouch 4G Slide] WeekendsR2Short:
You're having problems with every single 4.X series ROM you flash? Even with the original kernel that is supplied with that ROM? That just sounds SO weird! Almost as if you have a secured bootloader. Even with S-Off, that would keep it from flashing with the ROM. You haven't flashed a different bootloader sometime have you?
[T-Mobile myTouch 4G Slide] Unrelashade:
Stable kernels as well. I went all the way back to the absolute basics to try to make things stable.

I'm going to research how to do that... Is there a thread that introduces readers to pulling logs? I'll go looking for one.

Exactly! Even with the original kernel of each ROM. I bought the device used, so I can't rule out the possibility that the last user installed a secured bootloader. Here is what my bootloader says:

This information could of course be fake :P But if you guys say battery is probably not the problem then it seems to be a good idea to flash a bootloader from the forums...

And again thanks for your help, I am kind of moved haha :o
[T-Mobile myTouch 4G Slide] demkantor:
If you try to flash a new bootloader the only way to get soff again would be via the wire trick, more complicaed then the revolutionary method but better, at the same time not neccesary.

If you know how to pull logcats last_kmsg is easy, if not its still easy and a quick google search will tell you how
[T-Mobile myTouch 4G Slide] mattlowry:
Do you have this issue on stock also?
[T-Mobile myTouch 4G Slide] mojoffdawal:
A fresh battery wouldn't hurt. Before I rooted, my phone would have random reboots and shut offs once the battery went below 60 percent or so. I did factory resets and tested with different apps installed and only a new battery fixed it. Best of luck!
[T-Mobile myTouch 4G Slide] WeekendsR2Short:
Well, it was just an idea. From that info there, it would seem that you have the proper bootloader. That's exactly how mine reads.
[T-Mobile myTouch 4G Slide] Unrelashade:
Thanks for the info.

Ok, right now I'll not try flashing bootloader since everything seems to be normal.

What I did to get last_kmsg:

Open terminal app
Enter "su" to get root privileges
Enter "cat /proc/last_kmsg > /sdcard/last_kmsg.txt" to save current log.
Close terminal app.

I attached the last_kmsg.txt. What do I do with it now? I don't have knowledge to understand it.

I can't remember using a ROM that never crashed, but I'll try a stock ROM if nothing else works. However an old kernel of scverhagens CM 9.1 seems to work flawlessly if battery is not about < 15%. The newest r10 kernel on the other hand always immediately crashes when the phone is not charging. When charging I haven't experienced a crash yet. That's strange and makes me suspect my battery is the problem.

Thanks! I guess I'll try an Anker since I have seen so much users here using it.

[T-Mobile myTouch 4G Slide] prettyflybrownguy:

[T-Mobile myTouch 4G Slide] Unrelashade:
So, I'm reviving this thread, because I stopped writing only because my phone was broken. Now it's back and I'm facing this problem again.

I've tried a lot of the 4.x ROMs here from the forums, but all of them rebooted or shut down after 5 - 10 minutes after flashing. I also tried some without flashing gapps even, but still the same symptoms. Also tested it with my new battery, nothing changed. Even the scverhagen CM 9.1 ROM rebootet shortly after flashing that worked longer previously (guess that was just by chance)

Now I've tried the original image and it works! Ugh. So what can be wrong, any ideas?
