LG G3 D855: Problems after rooting (SD card, FM radio, Joyn service) - G3 Q&A, Help & Troubleshooting

Hi all
I just got a new LG G3 from T-Mobile which came with Marshmallow (30b). I have inserted my 64GB external SD card from my previous G3 (its' display stopped working all of a sudden) and started to set up the new phone. All went quite well until I have rooted the phone following the steps in Root + TWRP Marshmallow D855 (30b).
Now I have a rooted phone with TWRP, which is good, of course. But I think during this process the original kernel has been replaced by another one, is this right?
1st problem now is the 64GB external SD card which is not usable any more, even after formatting it through the phone itself. I have inserted another 12GB card and this is working as expected. The 64GB card is working normally in a card reader.
2nd problem is that the FM radio app stopped working. It is only giving strange messages like "Mock: RADIO_ON", "Mock: UNMUTE", "Mock: TUNE" and so on without playing anything at all. I have uninstalled and reinstalled the radio, no success.
3rd problem is the annoying Joyn (RCS) service. I can disable it in the settings. But after a reboot it is turned on again.
I am not sure about the 3rd problem but the first two may be very well related to a kernel lacking support for the big SD card and the radio HW, right?
Any suggestions how to solve these?
Can I flash another kernel without losing TWRP and root again? If so, which one?
(Is there a Marshmallow custom ROM with the original camera and FM radio support? This I can find out by myself of course)
Thanks and regards,
xrig

Had the exact same problem. I have the international model G3 32 GB variant which I purchased 2 weeks ago. It worked good till I rooted it. FM radio kept coming up with mock & couldn't get any functionality of the radio, tried rebooting, taking out the battery & didn't work. What solved this problem was downloading the 30b global Marshmallow rom & flashing it. FM worked perfectly, even after rooting & had no issues. I'd recommend flashing the 30b rom with a complete wipe.

Thank you very much for the suggestion. Did you use the above rooting method again after flashing the global stock rom? And can you use exFAT on your external SD card? It seems that Hacer Permisivo is breaking the exFAT support.
What global 30b did you actually use, the kdz corresponding to your IMEI from devtester.ro?

Maybe a custom kernel or ROM will fix your problems, and also formating your sdcard on fat32 will fix it.

[Q] G Pro F240K problem after rooting

Hi, Noob here, need urgent help.
I bought a g pro F240k a few days ago and was having signal problem and i read that changing the ROM may help.
I have done rooting and swapping ROMs before, but right now I have a problem, I rooted my phone successfully and then when i tried installing custom recovery, my phone no longer reads my memory card, it gives the option to mount the card but it fails to mount.
And another problem was that SuperSU is no longer working, it literally fails to open.
This is my primary phone so urgent help is needed.
EDIT: The SuperSU somehow fixed itself, working fine now, I succeeded in installing a recovery, but im still facing the problem with ext sd card. The recovery can read my Ext SD card but the OS fails to do so, still gives me option to mount but doesnt do so.

No Sim

Alright so I've had quite a journey here. I'm no stranger to Odin, Custom ROMs or Custom Recovery however this one has me scratching my head.
I was running one of the build 7's of SlimKAT with Devil Kernel and had zero issues for quite some time. I went to upgrade to stable 8 and when I booted up my phone it was saying "No Sim Detected". I then proceeded to reflash the stable ROM clean and with a Full Factory restore. Still no Sim. Next I used ODIN to flash back to Stock ROM, still no sim. My next step was to buy a new card, did that, No Sim. I then ordered a new Sim card port and replaced it myself, still no sim. I'm currently downloading the ODIN file from the thread here:
http://forum.xda-developers.com/gal.../rom-att-i317-ucucne5-mj4-stock-odex-t2802189
However Dev-Host is taking it's sweet time today and it will be 3 hours until the download finishes.
My question is what else can I do? Is there another problem I could have that is causing my Sim card not to read? I don't believe it is hardware because the Sim and MicroSD ports are on the same adapter and my MicroSD works perfectly fine.
This is the first time I've been at a complete loss with what to do. Can't afford to replace or upgrade quite yet so I really need this to be a fixable problem.
Thanks in advance!
Edit:
I also flashed the Modems seperately both on Stable SlimKat 8 as well as stock and none of that helped!

Transfer *EVERYTHING* To A New LG?

I just got a new G3 because my old G3 was having sim card reading issues. I'm trying to transfer everything from the old to the new*– and I mean everything: ROM, apps, contents of the internal SD card, etc. etc.
What is the best, most painless way to do this? The old phone, fwiw, is rooted with Cloudy installed as well as G3 Tweaksbox and some Kernel tweaks; the new one I haven't touched yet and is fully stock.
Thanks!

Come on, anyone?

Do a full backup in recovery, move it to the SD card and restore it in the new phone's recovery. Are you sure that the sim card issue isn't a Rom issue? I had this problem on Fulmics, flashed DU and had no problem since.

I'm fairly certain it's not a ROM issue, as my phone was working fine on Cloudy for months, but after a tumble started having issues recognizing the SIM, even after replacing it with a new SIM.
The issue comes up upon reboot; it seems that if I squeeze the phone tightly during the reboot around where the SIM card is, it will recognize it and then everything works fine, but if it was booted without being squeezed it won't recognize the SIM until a squeezed-reboot.
That seems like a pretty definitive hardware issue to me?

Yep, really seems like a hardware issue. But after you do your full backup and put it on the new phone you could try to install a AOSP Rom just to try out, but thats up to you.

SimCard not detected after flashing any rom

I am using desire 320 and used to flash many roms normally without any problems
then one day after i rebooted my phone when i was on cm13 rom (took off the battery and changed my sd card) the Sim card isnt detected.. i thought the problem from my sim and i tried it on other phones and it seems to be working so i tried to go back to stock rom to check and i found my sim is working fine
and from that day... whatever the rom i flash, the sim is not detected at all
tried different lollilops and marshmellow roms and the same problem kept happening to me
even the roms that they used to work fine a month ago now dont detect my sim (while everything is fine on stock rom)
I know this is really strange but if anyone have any idea how to fix that he can share it with us because i am kinda stuck like this in my stock rom... :/
(maybe there is some files i can backup from stock rom before flashing?)

Does Flashing ROM's causes damage to "motherboard"?

Hi to all Geeks, G3 lovers and developers,
I wanted to share this information and know what exactly went wrong with my phone.
Long back, My LG G3 D855 (32GB) was running Kitkat (v4.4). I used One click root to root my device. Auto REC Kitkat to Install recovery. Then i also Flashed CloudyG3 2.5. All were working fine.
Then i came to know about Fulmics ROM (may be v2.5). So flashed it. Everything was working fine.
After few Days.
I flashed Fulmics v5. (ALL ROMS I CLEAN WIPED i.e. wipe>Advanced wipe> wipe everything except internal and external memory). Problems Started from here. My device's memory card slot stopped working. It used to mount and umount frequently. Tried going back to older worked roms and stuff. Tried inserting other sd card. Tried formatting. NO USE at all.
After few days my device's screen started displaying lines, flashes lines, and finally display stopped working. I had to take it to service center and new motherboard was replaced. Now, phone has developed yellow tint on left hand side. Also running stock 6.0 v30E. :crying:
My question is,
1) Is there any solution to get rid of yellow spots on display? ( other than replacing a new one)
2) Did my motherboard fail due to flashing ROMS? Have you people experienced these issues?
3) I have heard twrp 2.7.8.x had mounting issues. Thats y i lost sd card mounting after flashing?
4) Will it happen again if i flash any other rom?
Or am i doing anything or any step collectively wrong?
PLZ anyone help me!!

It may be the LCD.
(Kind out of theme)
Personally my LCD had shown 2 or 3 dead pixels and the after a while it showed about 12 and it's visible to grey colour..
But give this a try.
Go to Google Play store and install "Dead Pixel test and fix"
Start the test and leave it for a about an hour.It may get rid of it for a while.. But i fully recommend to change the Screen.

I was having that problem with my t-mobile D851 on a stock MM 6.0 which I had rooted. The external SD card would not stay mounted and kept coming up with a corrupted file system. I tried both exfat and fat32 formats and long formatted under Windows (not the quick format). Also tried a different sdcard. I couldn't solve the problem. Then I installed CloudyG3 v2.5, but that didn't solve the problem either. Finally I went to Fulmics 6.6 and it's been without problem since.

I don't think so. Flashing excessively will take a toll on your motherboard flash memory, eventually after much flashing, but most people don't ever reach that point, the phone will probably get old and worn out before that happens.

Not likely. I think that the most likely cause would be some incompatibility between the rom and the phone, or possibly the microSD socket, etc.

You may want to try Fulmics 6.6 / 6.7

Hi, When G3 had mounting issues, i tried going back to cloudyg3 2.5. Faced same mounting issues.
Then i had to take my G3 to the service centre. They said motherboard was damaged. They replaced it.
Now, after being on stock V30E 6.0 for a while.
I Rooted and flashed fulmics 6.7. Everything is working fine
But as you said, flashing it to fulmics 6.7, sd card worked fine. I could not do this cos at that point off time fulmics 6.7 wasn't released.
Now, strangely yellow tint has developed on left hand side of G3's display. I should deal with this now :fingers-crossed:
