[Q] LG-E971 weak signal - LG Optimus G (International)

Hi everyone.
I was flash Korean Rom in my LG-E971. Really stupid - after reading some post . Now whatever I do - flashing stock rom, changing baseband, my E971 signal is very very bad - it drop very often. So is there any thing I could do to fix this problem ? I've read some few post saying that restore your EFS could fix it, but my problem - I didn't make any back up yet . So could any of you could share your E971 EFS back up file ?
Thanks for reading and really sorry for my bad English.
Happy New Lunar year everyone

Please share your E971 EFS . Please please

You do realize that EFS backups are device-specific, not just model-specific, right? Meaning that, if you restore from someone else's backup, you would assume their device's identity, including IMEI number...

Thanks for your info. So I know that impossible to share EFS with others. Is there another way to solved my problem ? . My E971 is now using ly Ipod (

Sorry, I don't know... But let's try and see if your EFS is really screwed up - a good indication of that is usually a lost IMEI (0000... or 0049...). If you dial *#06# on you phone dialer, you should see your actual IMEI - does it show the real one, or "fake"? You can also check it under Settings - About Phone. If your IMEI is intact (it would be nice to check it against the sticker on the box the phone came in, if you have it), chances are good your EFS is OK, and your problem is somewhere else...

It still have IMEI, but signal is very bad. Luckily My friend give me his E975 EFS back up. I've just flash it in my E971, and my problem is now solved. Singal is normal now. There is one thing, that now I have same IMEI with my friend. I hope is not gonna be a big thing cause he is living at other country. Thanks for your reply.Now I could enjoy my device again

Experiencing same problem

[Q] P936 blank IMEI, no service

Hi there!
I recently discovered that my phone has totally no service after about 2 weeks flashing with V20F rom so I flashed back to Hong Kong stock gb rom. However, the phone cannot detect the sim card thus still no service and when I check the IMEI with *#06#, only a blank box appeared. I checked the efs folder and it was blank. As my phone was unrooted, I sent it to the service center. Just now, they called me and said that they my phone is rooted and the problem cannot be fixed (did they really try to fix it??!!) and needed to change the m/b which costs HKD2000!!!
My question is do I really need to pay for the m/b or are there any cheaper ways to recover the IMEI??? I have searched on the web but there seems to be no such tutorial for P930 or P936.
Oh and by the way, I am not sure if I have a backup of the efs folder as I once installed CWR.
Thank you for your help!

I had the same issue well the window saying 'No network or wrong IMEI' so I too will wait to see any responses and I only put those numbers in because I heard that it may open up the internet speed or stop the drop of wifi signal, just not sure of any of that lol

I don't think yours is the same issue of mine as I don't have any error message. The IMEI is just literally blank. I really hope someone can help me. Anyway, thanks for your response!

Hi! No luck! Unfortunately, the above solution requires some sort of chip which this P936 hasn't. I will give the phone to a local electronic store to see if they have any clues. Thanks anyway!

When did you unlock with freegee? If its after February you have efs backups in /sdcard/freegee automatically

Since IMEI spoofing is illegal in most country, the IMEI is most likely encrypted. I don't know how it is input on the Optimus G, but I had an issue back with my Galaxy S, and let me tell you, just hope you have a backup!!

you cant find it. its INTERNAL
JTAG is a tool, made by RIFF, not just a software.Any respectable gsm service has one.Rewriting software with JTAG costs between 10 and 20 euros,depending on the phone.At least here in Romania it costs this much.Don't know other countries.
Bottom line, writing the IMEI it's not a DIY job.it can be done only with proper tools,on a specialised center.
I think there would be another way,but i'm not sure, you need to talk to shelnutt or autoprime to confirm or not.
If the EFS backup from other phone can be decompiled,and the IMEI section is find,change the existing imei on that backup with yours, recompile and restore it with freegeee.i repeat,this is just a theory.
Another question,what method did you use to unlock bootloader?

Even with a samsung, if you'd screwed the partitions real good, you'd lose everything, even the backup.

You can try it, but most likely not.
You would need to decrypt the file, replace with your IMEI and encrypt it. copy it and it "would" work, theorically.
OR, you could call your provider and ask them if they can do it. Might not be worth the hassle!

Yes I can resolve sending the phone in service...But my wife told me "don't to do that""
For me will a victory if I rewrite my Imei because in the future i will change new rom... and want learn how to...
how I can enter in Diag Mode?
you're not sending it for waranty, the "waranty" was void when you changed the rom. If your provider gets to know that they will void it "officialy".
You may contact the service to know if they can rewrite an EMEI, and ask them how much they charge for it.
The FIRST thing you should do before installing a custom rom is a backup of the EFS partition:
http://forum.xda-developers.com/showthread.php?t=2161611
or, if you have installed freeGee, you might already have a backup in the FreeGee folder in img format
If not, then you will need to open thoses .img, edit them with your IMEI and reflash them
Not that easy.i didn't find any tool to decompile those images into workable stuff.like i said,maybe you will find more help on irc channel.asking will not hurt

my phone work good and the network see my phone... but there's a problem... my phone and my wife's phone have the same Imei number.!!!

1) Have a backup folder. :good:
2) Change the Imei with my Imei number in Backup Folder .
I have to find a tool for change the number in the image...

[Q] Reboot after ROM start and no IMEI

I've got this situation with my LGOG E975: a week ago i turned it on and after like 20 seconds after STOCK ROM was running , it rebooted.Then I also noticed the IMEI had gone. I wasn't rooted and the bootloader was locked. I tried everything from hard reset to flashing stock kdz. The only solution to the reboots is to flash teenybin and then a custom rom. Although I have no service and no IMEI. It's like having a 32 gigs ipod, almost useless. Also warranty was voided because the phone was disassembled.
Reading around the internet seems a EFS related issue but I have no idea how to fix it
Whats your advice? Hardware or software fault?
PS Also I noticed that ,with the stock rom, it doesn't scan the memory at startup, like it used to do.
Any help/idea would be appreciated!

do you know where's your phone from?? I meet a lot optimus G from Korea with this kind of problem when owners tried to flash it with an international ROM (Korean versions use different ROM but you can flash it with international ROM with some CAUTIONS, or you lost your IMEI) look for an able-to-pull-out antena on top of it, next to heaphone jack. if there is one, that's Korean version.
I know one way to recover IMEI for those phones, may be it works for your case:
1. Find out what is your phone REAL version (E97x or F180L,F180K,F180S ...) because it can be changed after you flash new ROM.
2. FInd s.o with the exact version of your phone and beg for the IMEI back up from their phones with this tool
mediafire.com/download/iy0rhx8yv7lkvlb/IMEI_Backup_Restore.zip (cant post links)
3. Restore your phone with that IMEI with the same tool, your phone will have new IMEI and .... service (I hope so)
remember to turn on "USB debugging". the phone will restart after done (may be twice)
Good luck!!

actually, you dont need IMEI to be the same, just the same kind of version (eg. International ~ E975, AT&T ~E973 ...). we call that "fake IMEI" in our place :lol:
This methods works 100% with korean version, and some of my friends confirm it works on international version, even the AT&T's or Canada's (E973,E970). the most important is to clarify your phone's version, if you did wrong version, you have to "fake baseband". and then everytime you flash a ROM you have to do the 2 fake

LG-F240-EUR - Where to find it or how to fix modem?

Hi
I bought recently some refurbished LG F240. According to IMEI it was originaly a F240L. I had stupid idea to upgrade software to Android 5.0 so I downloaded original KDZ firmware for F240L. Update was succesfull and everything works fine except... GSM. I can use a WiFi but i can't make any phone call or send sms. When I check my phone IMEI using *#06# it shows "null"
I live in Europe so to fix this I tried to flash my phone again using KDZ for Germany (from this link: storagecow.eu/index.php?dir=Xda%2FLG+Optimus+G+Pro%2FStock%2F ) and it still dosn't work . After it I rooted my phone and I installed CWM (lte2jbrecovery) and I tried to flash all modems from this link androidfilehost.com/?w=files&flid=17567 but none of them works. I also noticed that after flash modem (CWM says that it was succesfull) broadband version in "about phone" section dosn't change.
My only idea is to install back LG-F240-EUR ROM but i can not find this rom :/
Does anybody has any idea how can I fix this. I'll be very grateful for your help!
i think all f240 are korean
so your safest bet will be to flash f240 k/L/S KDZ, when i messed up flashing rom to my f240 and get no signal i always go back to to f240k korean kdz and it will be fixed

I don't know how to do it but i found some company which do things like this so I hope that they repair this - they told mi that it should be possible

No idea. I did everything and nothing helps. I don't know what magic is done in LG-F240-EUR and I also can't find this ROM. EFS partition is ok, its probably something wrong with RIS driver but i don't know how to fix it. I just bought another phone and i'll never again buy another phone for Korean market.

Help with ZERO networks!! Before I burn this THING!!

Okay story so far, got Zuk Z2 from BG China to replace Mi5 that had a tumble
After a couple of weeks I decided to flash Custom Rom (LinageOS *UNOFFICIAL), seemed fine then I lost Network totally on both SIMS.... Zero bars! I've tried all sorts of ROMS and flashes of Baseband firmwares but to no avail. Now I think I've confused myself.
So if anyone has any advice before I cast this device from a high roof it would be most appreciated.
Thank you :good:
You flashed already different basebands via fastboot, erased modem after that?
Tried flash stock ZUI via qfil?
After all no network? IMEI's are there?

So if anyone has any advice before I cast this device from a high roof it would be most appreciated.
Thank you :good:

Since you are not first one, I would dare to say that you are toasted...

You flashed already different basebands via fastboot, erased modem after that?
Tried flash stock ZUI via qfil?
After all no network? IMEI's are there?

When it first gave up network I checked IMEI and it seemed to have duplicated them for both sim but after I QFIL back to ZUI 2.5 they returned perfectly... I've gone through the whole erase modemst process but still FUBAR....
Even stripped the device down to bits and checked the internal connections.
He strange part is I get the emergency only msg on sim so guessing the network is recognised but the signal is -90 dBm at best, getting to as bad as -130 dBm.
Even considering writing the IMEI from old bust Mi5 to handset to see if this would help...

I noticed it seems to be an inherent issue.... guess that's why this is a cheap powerhouse handset.

Yeah I guess every other android and iOS device I've either rooted or jail broke was pure luck and the huge amount of posts on many sites including Lenovo regarding this baseband problem are all very similar 'lab rat' experiments.
Thanks for the constructive advice and answering my plea, great to know that xda developers are attracting helpful and intelligent like minded users and owners....

Same problem here. Anybody please share the QCN backup (or valid link to download this) to try repair QCN and IMEIS ?

I had a dabble with QCN and managed to replace corrupt IMEI's but still didn't help. Can't be sure the BASEBAND was correct though.. I'm yet to try a full FACTORY DEFAULT configuration as suggested but will be this week.
Been suggested the IMEI may be blocked for some reason but seems unrealistic as it was working prior to FLASH.

I see other tutorial for zuk z2 pro with good QCN backup and the problem was solved. I need the good QCN backup to try here.
