[Q] Only Booting to Koeran Download Mode - AT&T LG G3

Alright. So a friend gave me an LG G3. And it only boots to download mode, and the language in the download mode is in Korean. I have attempted to use the 2 LG Flashtool to fix this. one shows Partition Error, other doesnt see the phone. offical LG Mobile support tool says the phone is fully upgraded. I cannot find an older version of the LG Mobile support tool to flash a stock anything becuase the tool auto updates to current version. I cannot find any CAB files for the D850 either for the CMD version of flashing. all i can find is KDZ files which I have leared how to use through the day. But still having no luck. I know Samsung and Odin. Not LG. I could use some help.
Model: LG G3.
Model: D850.
Carrier: AT&T.
Issue: Only Boots to Korean Download Mode.
Attempts to Fix.
Used LG Flash Tool
Error: Change Partition Error
Attempt to Fix:
Used other LG Flash Tool
Error: Program does not see phone
Attempt to Fix
CMD CAB Flash
Error: Cannot find CAB Files for D850
Attempt to fix:
Used Offical LG Mobile Support Tool
Error: Phone is fully up to date.
Other information:
Windows 7 could not install "LG Mobile USB Modem #2"
Unable to find This item.

UPDATE: So I found out that my friend played with the build.prop. And since the phone is in download mode. Im having trouble even figuring out how to pull the build.prop so i can edit it to fix not being able to flash a FW.
Can anyone help with that?

Yes, and after many trial and error, i got it to work. I got the phone fully working and i was beyond happy. so I bought an unlock code ($10) for it, and i went to put it in, i had to put it in a few times for it to take, but now it just keeps cycling between no service and and searching, but end result, i now have a fully working LG G3 with no signal with the SIM card i use, i popped the sim card back in my old phone, works fine, i called metro pcs n they said they can accept that phone no problem. so now im really lost, i re-downloaded the TOT and DLL and reflashed the phone twice just to be sure, doing a full wipe n flash. then doing factory reset to be sure I was making it a clean boot, but it still will not cooperate with my sim card. but it works fine when i pop a de-activated AT&T sim in it, But now any non-AT&T sim i put in, the phone doesnt really accept it. it doesnt prompt for the code anymore, but now it doesnt grab a signal.

[Q] Skyrocket no sim ... a posible fix

hi i know there are a lot of threats already of this but now i bring a posible solution to this problem
in my case is no hardware problem cuz i change it, i have falshed a lot of modem and still says no sim... insert sim
btw the phone is unlock. so i decide to leave my skyrocket as nonfuntional phone but i start tu play with the service mode
and suddendly recognize the sim card and get data and works great. but it only works until you reset or power of the phone.
if that happend you have to do my steps again and that way you get sim recognition again.
i post this cuz im not a developer i dont know to much about debuging mode so plp that know that can see my steps a find a permanent solution
to the no sim error on skyrocket.
before start you have to inserte the FUNCTIONAL SIM CARD and power up the phone, it will power with no sim error
un dialer put *#197328640#
enter to debug screen 1
enter to phone control 8
enter to simulation 5
enter to modem Assert (reset)
at this point it appear to dont do anything but wait like 30 seg you will see the signals would restart and then do this
press menu and choose end
there it is now it recognize the sim...... so it possible is something with MODEM ASSERT (reset) but this is a solution not PERMANENT cuz when you reset o turn off the phone you have to do this again to get sim recognition again
so pliz devoleper make a PERMANENT solution with what i found
i try this with an att skyrocket with UCL2 baseband and UCL2 oem root ics
if you guys try this or think it its not possible just post me and on the weekend i ll upload a youtube video with all the steps and you ll see that it works

I too am having a problem with an AT&T Skyrocket that is rooted. I have been using it without a problem with Straighttalk's AT&T SIM. I decided to switch it to T-Mobile's $30 plan and unlocked the phone. It worked except service was extremely poor so I flashed the SKY ICE 4.2E R5goo.zip and SKY ICE 4.2-17.zip ROM (T-mobile radio). This didn't work any better so I read that I should try a couple different radios. I attempted to flash the Blaze radio since that seems to be the most popular and after rebooting I get the no SIM error. I have reflashed the stock ROM using ODIN (several times) and now neither the T-mobile or ST SIM is recognized.
I found this thread and attempted to go through the procedure but there is no modem assert reset on my menus.
Any help would be a appreciated.

Did you notice in odin if it flashed files named mdm.bin and amss.bin? That's the radio.
In case you didn't (and didn't read the 1 stop thread), here are som links for radios:
A thread with only t-mobile radios (work on our phone too) and here are all the i727 radios.
Hopefully this will help, but really i'm just guessing, maybe someone else can spread some light on your problem.
I'm guessing (hoping) that for some reason the blaze radio failed to flash and so you got a corrupt radio. Then you flashed stock tar that didn't have modem in it.

Yes it did flash the mdm and amss bins. I'm suspecting something happened to the SIM holder since it will not read any of the SIMs (Tmobile, ATT or ST) I tried in it and have another on it's way. I'll see if that changes the outcome.

[Q] Wont recognize SIM card after flashing rom on MOTO G PLEASE HELP!

Hello, i recently thought about flashing a rom on my phone, i did all the basic stuff unlock boot loader, root etc but when i put the file on my device i got stuck in a bootloop, so i panicked a little and went on to google to find a STOCK ROM for the moto g. I found one and flashed that instead, it did infact save my device and i was so happy at the point, but then i noticed that at the top on my task bar it said i had no signal on BOTH Sdcards when infact this phone only has 1!? (my o2 simcard was in at the time) Anyway i went into setting and it had above he wifi setting "Dual SIM settings" which i have never even seen before. Anyway i clikced on that and it says 'SIM1 Disabled' and below it says 'SIM2 Disabled' Also my Mobile DATA has vanished to. All this worked before i went and screwed up my device. Im kind of in a panic and really dont want to loose this phone :crying: :crying: Please can anyone help get me back my signal and data, other then that everything else is working normal.
Screenshots Attached.

You have flashed a single sim variant of the stock ROM on your device, find the dual sim version for your phone here: http://sbf.droid-developers.org/phone.php?device=14
Also, of course your data has gone as your phone has undergone a reset and firmware flash
All of them are not for 4.4.4 or does that not matter?

Absolutely. From experience, you must flash the dual sim variant. Unfortunately, there is 4.4.4 available, but only for the States. You might PM me the OTA update package and I'll be able to help.

Cant find any for O2 uk or retail UK or duel sim or even 4.4.4

Hi men, I could fix it, i took it to a technician and he told me that was locked by at&t, of course i knew that, and that there was a server on the internet that could free that lock. I paid like 20$ on that page, honestly i don`t know what page is it but it was the solution, not flashing or even installing a new firmware

New g955u won't connect to Verizon

I'm about ready to throw this phone out the window, and hoping someone here can help me out...
My wife ordered a never used g955u off of ebay. It came with Oreo installed. It had the CRE9 firmware installed. We are on Page Plus (Verizon reseller). We put in her SIM card, went through setup, but we are not able to make phone calls. The SIM card works fine on her old phone. I reset the network settings to no avail.
I did a network search and selected Verizon Wireless, but it times out and gives the error :
No Service
Selected network (Verizon Wireless) not available
I talked to Page Plus, and everything looks fine on their end, they say it's something in the phone.
I suspect it's something in the radio settings, but I'm locked out of the service menu. I factory reset the phone, and that didn't fix it either.
I've been down several rabbit holes since then.
I tried to follow the steps in this thread: https://forum.xda-developers.com/galaxy-s8+/how-to/carrier-switch-snapdragon-t3615680 hoping that if they can make non-verizon phones work on verizon, then it can make a verizon phone work on verizon. I also tried to root the phone using this thread: https://forum.xda-developers.com/ga...root-g955u-g955u1-snapdragon-sampwnd-t3658911 hoping to get access to the service menu.
But evertime I tried to flash any of the necessary binaries, I got Fail! (auth) and the phone gave the error:
sw rev check fail : [boot]Fused 3 > Binary 1
or
sw rev check fail : [boot]Fused 2 > Binary 1
Turns out, you can't downgrade. And all the binaries in the tutorials are now downgrades.
Somehow in all this, I managed to flash the phone to CRD4. I tried flashing back to CRE9, but regular Odin fails without telling me what the error is, and Comsy Odin gives a model dismatch fail.
I tried connecting the phone to Kies, but it gives me the error "only the device owner can connect to kies" even though I'm running Kies as administrator.
I've ordered a new SIM card from PP, just in case that fixes it, but I'm losing hope here. If anyone can help me out here, I'd really appreciate it. If there's anymore information you need, let me know and I'll post it.

So I know Odin 3.13 at least. But other than that with Oreo I don't know
I wanted to stop by and mention I am having nearly the identical issues. I bought a used Verizon Galaxy S8 from somebody today, and even ensured that the IMEI was supported by Page Plus beforehand. I tried using an existing, working SIM card of mine from Page Plus but found that it did not work automatically as it should have. After going through four customer service representatives, I was told that my phone is somehow not compatible. Still, I think I may have a slightly different situation going on... I was told it would not work because there is no "LTE/CDMA" option in the "Network Mode" setting. Instead, upon inserting the existing SIM into the new phone, my Network Mode setting only has access to "LTE/3G/2G (auto connect)", "3G/2G (auto connect)", "3g Only", "2G Only" options.
When I put the SIM back into my working phone, it gives me the correct network options. For some reason, this new phone is not allowing me to connect to the Verizon network at all.
You've taken a lot more steps than I have... I figured it could be an issue with Android Oreo, but I am really not looking to delve into the degrading process. I will also order a new SIM and see if that magically fixes things, but it's starting to look like a lost cause.
Let me know if you figure something out - you are the ONLY person online I have found with my identical (or near identical) issues. If you happen to know any way around the exact issue I'm having with the Network Mode, that would be insanely cool.

Question Samsung S21 VZN need unlocked or converted to ATT. Tried odin.. Maybe I am an idiot.

Hello.
Got a free phone from a buddy S21 5G. I am wanting to swap it for the S10* 1tb I gave my wife to use it was a bit expensive. So I'd rather ti go back in the box.
Popped the sim in it, it works makes calls sometimes, sometimes not. Texts seem to always work, I am currently on ATT I would prefer to have that firmware as I live in the stick with ho cell service. ATT has wifi calling which is pretty much a necessity here.
So what exactly do I need to do to get this off the VZN fir
Hello. Could you all provide me the links for what I need? Found a link that had a patched Odin plus the firmware. I installed in booted how I was suppose to. Tried to install in and it errored out. Also. I do not know what file to select for the user data selection, I do not mind deleting all data as it 8s hacked up and can put ti back with smart switch.
Hello, did you manage to flash the phone?, I'm stuck with a similar case, mine is a factory unlocked unit from Verizon, it turns out that even if it is factory unlocked, is locked after a few minutes by verizon, I have tried everything to get rid of the VZW firmware but it seems that Verizon locks the bootloader so I can't flash it (it passes om odin and everything but the firmware doesn't change)
I even paid SamKEY credits to change the CSC but it didn't change either.
