[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!

same problem here

Same problem here using stock rom and no root.
Phone reboot after a few seconds and no signal, no IMEI.
Is there a way to backup my data/photos in LG Recovery Mode ?
When the phone boots up I can see the files on pc but not enough time to save.

I have jtag but it's possible to restore imei for our device(only for htc devices).Only bootloader.
Search for someone with OCTOBUS BOX.

solution suggest

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

Anyone?

i have same problem

Same problem. To those with same issue, haven't been able to fix? I had my phone checked in a local service center, and they say I need to have motherboard replaced. But I doubt the hardware is the problem. Anyone have ideas?

Not sure yet what is the problem. Using custom roms and various modems did not help.
No network and phone is quickly discharging and very hot.

Quick discharging of the battery/very hot I think is due to the phone constantly searching for network signal.. I removed my SIM while still looking for a fix, and this helped with the battery.
I can still connect to WiFi but other than that, it's not really a phone if can't do calls/sms..

Mate! Did you find a solution to this problem? I got my phone off ebay.in and after the lollipop upgrade the same thing happened. If you got a solution can you help me out as well?

same here my D855 was changed to D855V by octoplus now need a way back, also here no signal.

Worth a try?
Have the same problem. Asked around in the market from the tech guys. According to their understanding and experience we should try flashing it with a d850 rom as they believe the phone is actually a d850 model. Would have done it but i don't know how to unbrick incase anything goes wrong. so anyone willing to try and if does let me know about the results

Well i just bought the phone last week. For me there is a lot to loose. Right now i'm just not getting signals. Rest of the phone is working perfectly wifi,cam, music etc. =p

Flashing with d850 will kill it, I tried and now dead, it was a d855 and became d855v after octoplus.

Can you please elaborate what you did and what was the result?

I have found a lot of threads and people reporting this issue. Bought a D855 32Gb from China that has this problem...
Phone tries to get signal a couple of seconds and then a cross.. and so on..
I tried everything I think, I passed for all the bricks the phone can do: Automatic Reboot / Boot Loop / Fast Boot / Security Error / Factory Reset Status 2 / Dead (QHSUSB_DLOAD) - I can help anyone that has any of those problems : )
In one of the flashes my phone turned to D855RE, similar case to other people, also the message "Current version is not available for user. Can't find matched cust for NT-Code mcc/mnc".
Please if anyone was able to fix the problem report here, there is a lot of people waiting for the answer 20 threads in different networks, I will post the solution in each of those. Thanks!

no network

You can also update via kdz or tot, take a look at this: http://forum.xda-developers.com/showthread.php?t=2785089

Maybe it's a problem of your network, or maybe just the server is off (?). You should try later :v

No. I have exact the same problem.
When i try to update it with LG Mobile Support Tool, i got the message that the mobile is uptodate. Due it has only ver 4.4.2. So i tried LG PC Suit, it finds a new update, but after a while some error message shows.
There has to be more than me and suxxes that have this issue.

hi, go to this site: http://devtester.ro/projects/lg-firmwares/
there you will find the latest update for your phone. just enter your imei number, download the file and flash it.

I did exactly as you said. Searched for my IMEI no. and got one hit: D85510A_00.kdz
I installed the drivers and LG Flash Tool 2014.
Everything seemed to work, Apart from LG Flash Tool 2014 that showed a lot of question marks (??? ????).
When the flashing was done, the mobile started up with the installation/configuration as usual. But what is this?....still Android 4.4.2!!! What the heck!

I have a unique version g4 and am stuck in "ILAPO" with no warranty.

Hello. i have a few posts from a while back about rooting my g4.
It turned out i had some weird beta version of the bootloader on it but i was able to update and root it still.
Well, now just a few months later. My phone just starts restarting over and over and will not boot past the lg logo.
After some research i found that most g4 made before September of 2015 had this problem.
So i contact customer "support" and they cant find my imei in there system. After talking to 3 different people one of them finally said that it shows my phone is a beta phone made in 2011 so they cant honor a warranty.
They said that they wouldn't even have the parts to fix it if i were to pay.
They told me to contact lg Korea but couldn't give me any help in contacting them.
Anyways. I came across the fix https://www.reddit.com/r/lgg4/comments/45gfg2/dae_g4_series_msm_big_core_disable_tool_guide/
But it appears that my phone model h810 (att) is not supported.
Also im pretty sure i was on marshmallow (honestly cant remember).
Is there any known fix for the h810 that anybody knows of?
And if i try this and it does not work, will it prevent me from being able to recover my data if someone does make a port for it?
I downloaded the zip but i dont want to flash a tot for another phone on here yet.
Any help would be appreciated.
Thanks.

I doubt it is an 2011 year model. Look at serial number behind battery. The first three numbers are manufacture date - for example 505. First number means year (5 - 2015), other two are month (05 - May). Maybe you might have provided Serial Number rather than IMEI for them.
As you still have locked bootloader, contact the place where you bought it as you should still have guarantee. Either they will take it to fix it or they should give you contacts for authorized repair.

to make the modded KDZ work on your at&t you need to renamed with hex program phone model. the kdz is for h815.... read this page..
http://forum.xda-developers.com/g4/help/lg-g4-stuck-bootloop-t3268734/page72
well you need to be on LP if you were on MM.
i guess youll still need to downgrade anyways. to be safe..

My serial starts with 503, when i first got it it had software vo9e but i updated since then.
Im not sure where they came up with 2011 but it would make sense . maybe 2013 as a beta test phone.

Yup. Now its really a brick. Dont try that.
Cant even boot into upgrade mode now.
It will vibrate as if it was turning on. but wont even show the lg screen.
Should have just put it in the oven. That made more sense.

Hi,
After upgrading from 5.1 to 6.0 my G4 got some issues.
First of all when i turn it one never turns the creen on. I had to do a work around using the USB cable to get the screen on and that doesn't wark very often eatheir so its preatty annoing.
Second the sim is not working.
I tryed many time to roll back or flash a new firmware but it didnt work.
I also find out when the phone is in download mode that is says LG-H818 but mine is fore sure a H815.
Is it some way to fix it?
Thanks

I just connected the phone to LGBridge and it notified the marshmallow update. I dont' know why it flashed a h818 rom

Does anyone know if there is a way to put the H815 firmware back? right know it believes to be a h818 so it doesnt allow me to flash it. WIth the h818 doesnt even turn on right now

Is ur phone recently repaired by lg or did u bought it used ? Cuz there is no way lg bridge can make mistake on ur g4s varaint...either someone u bought off tried to change the buid prop file to make u believe its h815 or ur phone is refurbished/repaired using components n sensors of other model

I bought it from a guy and the phone was totally new ( it had all the protection film on it and even the box was sealed).
I'm starting to think it was regenerated but i dont understand how could it be the dual sim one.
Do you have any suggestion how to fix it? right now i can just uplad h818 firmware from lgup but of course they are not working

Its probably refurbished ...if i were u i wont try to tinker any software things u might probably brick it so most probably leave it as it is good thing to know that atleast ur phone wont bootlooop like the rest...try contacting the person u bought it from or check it if its under warranty by lg from him

Right now its already rebooting aftern turning on, so i can not se how could damage it more. Any suggestion for possible solution?
