How to restore d550 software??

So in a moment of stupidity I somehow was able to install a D855 rom on my AT&T D850 phone. Turns out these roms wont let me hear my phone calls and continually drop my data connection and cell service. Turns out I made another stupid mistake and forgot to make a backup of my phone . So I tried to do a factory restore back to D850 using the LGflasher method and I can't because I now have the D855 software on it and so I'm now stuck without the ability to make phone calls or have a reliable data.

What exactly have you flashed on your phone? Bump, root, KDZ/TOT file?
If you want to go back to stock you could either follow the guides on the forums or flash a .tot/.dll on your device, that way you get stock recovery, boot and rom etc..
I could link you the guides, but they are all in general forum or on Google
Good luck

So I used iOroot to root and then bump to put twrp on my phone. Then I decided it would be smart to flash the AndriodNow rom and then later the SphinX rom. I have tried to go back to stock but the lgflasher thinks my phone is a d855 because of the roms I flashed on it.

Data icon missing and sim contacts MM please help

Hello I have the lg g3 D855, it was 5.0 20T rooted. I installed MM by this method http://forum.xda-developers.com/lg-...855-30b-images-kdz-flashables-t3282012/page89 but every try I have two issues : no sim contacts and no data icon even if the phone connects to 3G/4G and sim recognized.
I tried N&N Rom 1.3 too .
I have these two issues with every rom based on the v30b firmware :/
after a lot of searching I decided to flash the kdz ==> sim contacts are here but no data icon !! and when I root with kingroot+autorec method ===> no sim contacts too
Now I downgrawded to V21A :/ using LGUP
I hope u will help because I want MM :/ I'm not the only one facing this two issues ..
thanks

LG G3 D858HK flashing Fulmics ROM 5.3

Thanks @xpirt makes a nice rom for G3.

D858HK has not many custom and I really want to try Fulmics even it does not support D858HK.
So I look around and finally in Chinese forum, found a method to flash Fulmics.
On Fulmics ROM 5.3, my D858HK works smoothly and the battery performance is similar to stock rom.
Everything is ok and I can use 4G. (I use one sim, two sim is not test.)
The only problem is the IMEI is lost (but I can still give and receive call) and the advance wifi in setting will force close.
I don't know whether it is work for your phone. I am not responsible for any harm to your phone , I am just sharing what I did to flash the rom.
What you need(in my case):
stock 6.0 rooted rom
TWRP(I use the unofficial twrp_3.0.2-0_d856_16-05-14)
http://forum.xda-developers.com/lg-g3/development/recovery-twrp-3-0-0-0-t3309475
Attention:You may lose you IMEI.
Follow these steps:
Make a whole backup of stock rooted rom in TWRP and you must backup the boot, modem, EFS and IMEI. (because if you lose the IMEI, you cannot go back to stock via KZD,TOT and LGUP.)
Put the Fulmics ROM 5.3 , dual sim v4 and modem5_6_3 into external sd card.https://drive.google.com/open?id=0B-NY-GIlMMxSV0tMSmtEYndIMmc
Ｗipe everything in TWRP. (Be careful：Don't wipe your backup)
Flash Fulmics, you just choose d855 in aroma installation.
When finish the installation, don't reboot, you should go back to TWRP and restore the boot and modem and then reboot.
After reboot and setting,you will find your phone cannot detect the sim card and wifi do not work.
You need to flash the dual sim v4. (please note that it is in Chinese)
If you lose your baseband and no signal, you can try to flash the modem5_6_3.
I found the dual sim v4 and modem5_6_3 in Chinese forum and they are made by @piaoxue99
I don't know these file is trustworthy or not but thanks @piaoxue99.

Hi, this sounds nice! Are you able to activate LTE on both SIM slots?

Excellent process has successfully ..... thank you

Hi GaryfromHK,
I have successfully installed it but i have noticed the following: Do you have any solution for these?
FM Radio is not functioning (even i installed the modem you provided)
I lost signal whenever I select the both status (my phone number, model no. IMEI, etc.) of sim card but it goes back normal here’s the error message “Unfortunately, the process com.android.phone has stopped”
I cannot activate guest user there is pop up error always
thanks and hope to hear from you.

We should be calling developers attention helping us out with this very limited ROMs for our beloved dual SIM LG G3

lg g3 no service detected !

Hi everyone
i have an lg g3 d855 EU working just fine for 1 year and a half ,
And lately when i upgrade to Marshmallow and then i stated flashing a different custom roms and they all work fine!
But a week ago I got a strange problem! A sudden msg appear for few second and then phone keep rebooting:
“Mobile network will be unavailable until you restart with a valid sim card”
I’ve done a lot of research and tried them all but still the same probe:
-put a piece of paper on the top of the sim cad
-replace the sim card
- Factory reset
-flashed android 5 the original kdz file got from official lg firmware using my IMEI
-....
So I decided to get it to a technician!
-so he replaced the sim card reader with a new one! After that the phone went just fine for 4 days and then the problem come back, so I get it back to him, so he replaced the reader with second new one and he told me that the reader is not the problem and is 100% working so when I put the sim card and reboot it ask me for "pin code" but when I after put the pin code, the phone keep searching for signal for few second than it stay no service at all.
the technician sad that there is some file in lg g3 responsible for the service detection and stuff like that only be obtained from another working lg g3 and only solution is that he can get those fil from a working lg g3 and put it into my phone and he told me it will be working again for sure !
So please guys help me I’m stuck !! Is there anyone know something about these files or their names?? And if he can provide me them I’ll be so grateful. :good:

Haven't seen this problem before. A file issue? Perhaps do another complete factory reset then do a complete wipe flash of the global rom, using the LG flash tool. Get the rom here http://forum.xda-developers.com/lg-g3/general/lg-g3-android-marshmallow-discussions-t3216143
I use that rom so there shouldn't be any issues. Hope this helps

You have to install flash stock 4.1.2 F180L KDZ again (yes! the korean one). Regarding IMEI/ No service, no one can help u if the EFS partition is lost (because that contains the phone info to be registered on the network).
The bootloop u had at CM13 has even easier fix than all of this KDZ mess. When I had my E975, The problem I had was no signal in CM12.1/CM12 so I had to resort to CM11. The F180's are so much falling into this crossflashing mess that its difficult to diagnose what can be the culprit.
Get the JB firmware flashed and check if u have imei.
