[Q] Can't boot any ROM! - G2 Q&A, Help & Troubleshooting

Well, I think I need some help with this one.
So, I have been using Resurrection Remix as my daily driver for a while now (to be able to run lollipop). As I noticed the G2 now has an official lollipop build, so I wanted to install that(cam sucks on most ROMs and overall stability isn't always great). Since I figured the best way would be to go back to stock, and then run the OTA updates.
I made a backup of my current rom, found this, and tried the TOT method. Everything ran fine, but when the 85% reboot thing happened, it booted straight into TWRP. Decided to reboot to system via TWRP, but after showing the LG logo for about 5-10s, it goed straight back into recovery. Since i figured the install failed or something I decided to factory reset, and restore from my backup. TWRP says the restore is succesful, but it still won't boot into my ROM. Reinstalling any ROM doesn't work either
Already tried this, no result(, and I'm afraid of trying the above guide again, but let me know if i should just try again)!
I do have access to my recovery and download, and ADB still works. The only thing I see is that instead of this:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Mine says this:
(My PC is in Dutch )
(The LG Driver on the guide was an older version than the one on my pc still, but I don't think that will cause a problem).
Hope my phone isn't gone forever, and thanks for helping in advance!!

EDIT:
Tried the above TOT method again, apparatly it skips a lot of things, and is done in like 30s, so it's not doing its job. I have no idea what's causing that though!
EDIT2:
IF ANYONE STILL FINDS THIS, this was the solution for me. I didn't know LG had a 'official' tool for fixing our sh*t . Hope it still helps you!

You should edit the title to include the word (solved) or (fixed).

Need to think this through...
you can go into download mode right? then follow this guide to install fastboot.. then the phone will bootloop. Just download cwm or twrp from android development section and flash using fastboot.. then install any ROM...

Can't Re-Unlock the Bootloader

I read through the similar thread from yesterday, but this is a different issue...
I had unlocked, installed TWRP, and had been running a custom ROM (BadBoyz 1.2). This morning I re-locked so I could flash the updated firmware (v1.80) and now I am unable to re-unlock.
When I issue the command fastboot flash unlocktoken Unlock_code.bin, it works without errors, and the phone goes to the "Are you sure you want to unlock your bootloader?" screen.
However, at that screen, the volume buttons do nothing. I can't select yes OR no, it just sits there. Eventually it times out and just shows the battery charging on a black screen.

When I flashed the firmware, it removed TWRP, and with a locked bootloader, I can't re-flash it.
I was able to get a fully stock rom up and running, so I'm not in brickville anymore (had a few hours of panic earlier today), and I've been able to confirm that the OEM Unlock option is checked. I've even unchecked and re-checked to be sure. Everything works except the ability to confirm my choice and move on. I'm kind of afraid that it's a glitch in the new firmware, at this point...
Anyone got any ideas?
Thanks!!

So, it removed TWRP and replaced the stock recovery? And now you can't reinstall TWRP because bootloader is locked? Is that where you're at?

have you tried running RUU.exe? i took that route and was able to unlock my bootloader again, flash twrp and upgrade to bb 2.0 with no problems
I had the same problem and had to flash a stock rom back on the phone before the unlocker would work.
I figured it out! I can't explain WHY it worked, but it worked...
I had re-flashed several times using the official RUU, and the results never changed...
Then yesterday I went through a mental checklist of what was different when I unlocked the first time... and the only thing, was that I hadn't put my SD Card in the phone yet when I unlocked the first time. So I went through the motions again to verify that it still didn't work, and it didn't. Then I ejected the SD Card and tried it - and BOOM, I was able to unlock!
The only thing I can think of is that the SD Card did have the Firmware .zip on it, which the phone auto-detected and asked if I wanted to install... even though I said no. As soon as I tried it without the card, it worked like it always had, I'm back to unlocked, and back to the custom ROM I had been enjoying so much...
Thanks for the tips, everyone, and I hope this thread helps someone else who finds themselves in the same boat!

Galaxy J5 SM-J500FN stuck on boot screen after flashing custom ROMs

Hello to everyone,
I hope that someone can help me at this point where i'm stuck on bootscreen after i flashed an custom ROM.
So, let me tell you my story.
I have a little of experience with flashing custom ROMs. And on my personal phone (Galasy S5) i succesfully installed over and over again custom ROMs. I really like the ROMs from AOSP Extended. They are covering all of my needs. So today i have an Samsung Galaxy J5 SM-J500FN. It is having some problems with the capacitive buttons(Back and multitasking buttons); those are playing however they want, so you can realise that entering in some app and your phone exiting fro it by itself is very annoyng. So on my S5 i have an option that can disable those buttons for good. And i wanted to install the Android &.1 Nougat offered by AOSP Extended today. So i ve got the TWRP from the official website for the right model of the phone (J500FN) and put it succesfully on it. I downloaded the ROM from official AOSP website, and succesfully installed it on the phone whithout any error. Then i installed the GApps nano, again with 0 errors. And when i was relaxing a little bit hoping that everything it s allright, when i wanted to boot up the phone, it froze up at boot screen (At the moment with that logo with Samsung ... powerd by Android). Then in a couple of seconds it started to turn to an green screen and then to an white screen. At this point, everything is frozen. So i removed the battery and entered in recovery mode(TWRP). There was no problem (only with those capactive buttons that i want to block).. But anyway, i donloaded several ROMs and nothing so far. I tried with anoter TWRP version, samething, stuck on boot screen.
Until my first atempt to flash the custom ROM, the phone worked just fine, only that those buttons ware going crazy. But now, i can't start it up in every mode i can think of.
Can anyone help me with this, please?! Any ideea of how to slve it?
TWRP version 3.1.1-1 j5 nlte
Firmware version: AospExtended-v4.5-j5ltexx-20170816-2007-OFFICIAL
Phone version: SM-J500FN
Tried with various TWRP versions and ROMs. Installing with and without GApps. All the results were the same like in the pictures below:
1) Start up like a normal Android phone

2) The the big surprise
3) Getting colorfull
4) Advancing...
For now, i can flash with Odin any version of TWRP, i can flash from TWRP any firmware, but i cannot get it boot up normally.
I don't have any backups from stock firmware so, please don t ask me about that.
Thanks in advance...
Look at the aosp file you downloaded. It says j5LTE.
Your device is j5nlte not j5lte you tried to install the wrong file.
Simple as that.
And if that isnt your problem you may have the wrong bootloader and modem but changing that is easy just follow the guide here https://forum.xda-developers.com/ga...5-1-1-bootloader-modem-j500xx-t3566801/page15

Boots only to TWRP - Need help fixing

Hi there. About a year or so ago I went about flashing my Tab but it went wrong and now all I can do is get it to boot to TWRP. Would someone be so kind as to tell me step by step what to do to get it back working? I'd prefer it to go back to stock ROM without TWRP or other 3rd party flash programs but I'll take what I can get. Help appreciated.
This is what I get when it boots:

Did you try booting to DL-mode (via adb reboot for example) and flash a stock ROM with ODIN?

I got a reply! Thank you!
No I didn't try that. To be honest I used to flash android stuff all the time but kind of having been doing much of that stuff the last few years so I don't remember how to do any of that. If you were so kind to provide me a link or walkthrough on what to do that would be HUGELY appreciated. Thanks for the reply.

What was the goal when you started down the path of installing TWRP? It seems like you might have been part way there if you got that far?
There are Lineage install instructions here. <-- More importantly Odin Download if you don't already have it.
If you decide to try Lineage, the latest builds require new firmware found here. It can also be obtained by returning to stock and updating.
Anyways If you are in TWRP, in the restart menu there is an option to restart to download. If will reboot to a black screen, just hit the power button once when the screen goes off. Before you do this, you need to obtain stock firmware, from somewhere. (Sammobile or something like that) You will also need Odin, link above.
As with anything proceed at your own risk.
Once you have those files, you can extract the firmware. They will be labeled and go into those spots in Odin, AP, BL, CSC, then you should be able to hit start. I'm going from memory, as I haven't had to restore mine since I got it (and looking at the files in stock firmware file).
Idk how relevant this is anymore but I had this same issue after I install lineage 18, there's a multi-disabler zip I got awhile ago that fixes all my flashing problems related recovery loop. Just Google that zip, flash it then format and restart. That what I've done easy fix, this assumes you followed the basic steps to properly flash whatever it is you're trying to.

Wifi and sim doesn't work

I don't know if this is a right thread for that but I tried somewhere else and no one was able to help me.
After some fun with magisk modules I got stuck in fast boot. I reinstalled a stock Rom because the one I was running wouldn't work for some reason. After first boot the '' android setup stopped working '' pop up came up the screen and when I tried to log into my wifi it automatically turned itself off.
Sim cards doesn't work either. I tried many different roms but any of them fixed my problem. I don't have much knowledge about this stuff but I know how to flash/ root my phone so I know it was a module fault. If anyone had a simmilar problem and fixed this please help. I've been trying to fix this for 4 days now and nothing worked. Sorry for my English I'm still learning.

CN version I guess?
try to flash the rom which was on it originally and relock the bootloader but be careful not to go wrong otherwise the phone is dead.
or try with miphone assistant(repair option).
Go to *#*#4636#*#* and see if you can copy config, just paste all your data for wifi
