[Q] SM-G900L Phone unable to use 4G in Australia?

As the the title suggests,
My dad's boss purchased this phone and while it works with any sim you place in it, upon turning the phone on, it basically summarises the following,
You have inserted a USIM that is not part of LG U+, and as such will be data locked.
(not word for word quote)
Now I take this to mean that the phone was carrier locked to Koreas LG U+, but the phone works here, and phone calls, and 3g speeds, but no 4G/LTE.
The current firmware version on it is 4.4.2 with I believe G900LKLU1AND3_G900LLUC1AND3_LUC
Now I've tried many different things to try and fix this;
I've read that 4.3+ version is bootlocked, (not exactly sure what this changes)'
I've tried flashing an Australian SM-G900I firmware (thinking the bands will be fixed, as its a software not hardware issue as far as I can tell)
Upon trying this, Odin throws a failed error, the download mode on the phone freezes, I can reboot it, and it's all good and dandy.
I then looked around and found that its possible to put in a SIM unlock code, however I query how that would work as the sim already works, just not LTE/4G
I tried Chainfires Region Unlocker (yes I know it said only tested on Note 3), which said succeeded, but actually did not enable 4G.
And I also saw a rumour that, if you place a phone call for 5+ minutes it will unlock said phone restrictions. In the phone logs it does show a phone call occurred previously before this phone was purchased, not sure if it was 5 minutes, but this may have been the case.
I'm stumped as to what can be done to flash this phone (or whatever can be done) in order to force it to allow the LTE/4G Networks,
Just to re-cap for the tl;dr,
4G/LTE not connecting as the phone mentions it restricts it due to being a NON-LG U+ SIM upon turning the phone on.
Please help ?

Hi
I also have g900L and had issue with LTE at the beginning But I resolved the issue by the following;
Please dial 319712358 and they will show you a box where you need to enter password then enter 0821.
This will lead you to the hidden menu page where you can find network mode where you can switch it to 4g mode.

I will pass this info on to the guy that owns this phone (my dad's boss) and hopefully all good,
Thanks man ,
Will post back here once I find out if it works on his phone.

Hi, just wanted to let people know I've had this same issue. Bought a G900L online and the network would connect to Optus' 4G/LTE for a few minutes at start up then will automatically go back to 3g. The solution above seems to have allowed my phone to lock to the 4g network.
Thanks

[Q] No carrier signal - damaged HW after L update?

After updating to 5.0 my Nexus is kind of stuck in airplane mode.
I usually turn to AP mode at night. Yesterday morning, I turned AP mode off, but I didn't get any carrier signal. The AP mode icon is not there, but when I try to make a call, I get the "turn off AP mode" message. Wifi works fine, but I can't make any calls or receive messages.
First time it happened, I removed the SIM, rebooted, put it back in, and it was back. This time, it doesn't work. I tried another SIM to no avail. I even rooted, did a full wipe, but the problem persists.
Any ideas?

Solved!
I flashed all of these modem images:
http://downloads.codefi.re/autoprime/LG/Nexus_5/Modems
Should have done it in ascending order and not from the newest, as only the second one worked, lol
EDIT:
Not.... signal is gone again and I get random crashes. Trying to install vanilla Lollipop.

I tried everything I can think of. Even reverting back to KK. Still, no signal. I got some the other day, but soon it disappeared. It's probably a HW error, sadly :crying:

Is it possible that my antenna was damaged because of the L update? Am I the only one who has this problem?

Can you check your IMEI in About Phone => Status? It may be that your IMEI was lost during the update.

I already relocked the phone and sent it back to the seller for a reclamation. Hoping to get a new one by Xmas

LG G5 Sim not detected only for SMS and calls

As stated I'm using the LG G5 H830 T-Mobile variant. I am getting 4G LTE data connection and everything runs well (Not in any WiFi range) Yet for SMS and calling as well as mobile hotspot I get "No USIM card' error. This happened after wiping the system and formatting data. Rebooted recovery (as per instructions on forum) then installed the stock firmware & Patch with systemless root and xposed. After this I did factor reset when just pulling the sim didn't help. Still nothing. I reflashed just the stock firmware with TWRP and SuperSU and issue is still happening. I've disabled rebooted and enabled the phone radio. SIM is in good condition and tray as well everything is SECURE and should be good to go.
I'm assuming a new SIM might be a solution. But I'm not counting on it and with Labor Day tomorrow for me I wouldn't be able to pick one up for 2 days. So here I am...hoping someone might have a fix. I know I don't have many posts on here. But I am an experienced user....just not with the more basic of problems I guess
Thanks!!

Has anyone else experienced this yet? I'm just curious...I had it fixed for a couple days. I've formatted data and done complete system wipe. Tried it resetting phone with the COMPLETE zip and TOT using LGUP. I'm receiving texts. Not calls. Not able to send either. I've activated new sim, didn't help. LG support just told me to look into warranty. T-Mobile needless to say just wanted. Sim card does show stock tmobile short code contacts but phone number shows as unknown. Hotspot won't work. I've tried setting the phone number to the sim. Nothing.
Anyways. I don't think I messed with anything, even so I've done everything to start the phone from scratch. Going to replace it, just more or less curious at this point and maybe others have had the same issue.

I believe I had the same issue as you and it was driving me crazy. I was constantly wiping data, system, etc but my phone kept giving the message "roaming indicator off" where it should show the name of the carrier. This resulted in me having LTE data and that's it- no 3g, no phone calls, etc. I couldn't even access the mobile network menu.
What ended up causing the issue was the network mode setting under wireless networks. Keep in mind at this point I'm running a patched rom which now gives more options in the network mode menu than the phone came factory with. I have an area at work where I have to switch to 3g, GSM/wcdma preferred network setting, because although I have full LTE signal, my connection goes dead. When switching back from 3g I chose the setting lte/CDMA thinking this would force my phone to stay in lte mode due to another area on an upper floor where the phone will constantly drop lte.
Anyways this resulted in my phone saying roaming indicator unavailable, the inability to make or receive phone calls, and either the mobile networks or network mode menus being grayed out. When stuck in this mode there is no way to put the phone back into the standard "GSM/wcdma/lte" mode. Even a complete reflash won't fix it. I even used lgup, which worked for maybe a day until it force closed the phone app and went back to roaming indicator unavail. I wiped every partition and even reflashed radio firmware. Nothing worked.
What ended up fixing it was using an app called v10 hidden settings which allowed me to access the network mode menu directly and re-choose the lte/wcdma/GSM setting. Incidentally on first access to this menu through the app there are only two network settings available. Once you choose a GSM setting, the rest appear.
I'm not sure if this was your issue but I hoped this helped because this took me about a week to workout.

Software Update - G955USQS5CRI4 killed 4G/LTE icon in notification bar?

I got the Sept Software update which installed baseband version G955USQS5CRI4, and now the 4G/LTE icon just shows the no signal icon. Calls work so it is apparently just an icon issue, but is anyone else having this issue?

Apparently it killed the data connection as well now, calls do not work with WiFi and WiFi calling off. This is bad.

Just checked my phone and all is good.

Yeah, not sure what happened but I had to reset all network connections and reboot 3 times for it to work again.

I've tried doing a factory reset about 10 times as well as network specific resets, and I have not had any luck resolving. They also replaced my SIM car4d with no luck. Any one else having this issue had luck resolving in another way?

I responded to another thread about this... having same issue. Here was my reply:
I am having the EXACT same issue. I don't remember when the last update came through, but it was Feb 16th when this started happening to me. I was moving to a new apartment, phone battery down to like 10%, so I turned the phone off and put it away. A few hours later I turned it back on and no cell connection. No bars, just a circle with line through it. Settings > About Phone > Status > SIM card status = shows Network "unknown", Mobile network type "unknown", Service state " Radio off", Mobile network state "Disconnected".
My SIM works in a Nexus 6 and Galaxy Note 4, so I know it isn't the SIM card. I've tried everything I can think of to turn the radio back on, replaced the SIM tray (original is cracked), even got a Freedompop SIM just to test, and yeah, it won't work. The cellular radio isn't turning on for some reason.
I will say, a couple days after it happen, I turned the phone on without SIM tray, and I could see empty bars, like it was trying to work. I turned it off, put my SIM in, and it worked... until my replacement SIM tray came in. Turned it off, replaced SIM tray, and it is off again.. for last 2 days. I just happened to turn it on that day and it was working, turned it off some days later and it stopped again. I don't know why.. no apparent reason. So, last couple days I have been turning it on and off, on and off, hoping it comes back on.
If ANYONE comes up with ANY ideas, please let us know!!!

Yea if anyone comes up with a fix for this that would be great, since that update my phone aswell has trouble deciding allow calls to ring or go straight to voicemail. Also noticed a delay in receiving text messages, unsure. I really dont want to have to replace my phone because of a broken update. :/

Cant connect to network or change network from "Global"

Device: G955U
Carrier: VZW
Starting Firmware: PartyCyborg Rom (Root)
Current Firmware: 5DSC1
So having a strange issue hoping someone can help me with.....
Woke up this morning phone was working, since my phone was charged I turned off "Battery Saver Mode" and after i did that I lost network connection. After checking that the network wasn't just down I began by flashing to stock flashing "3CRE2", thinking maybe something in the software no go.
Decided to apply the stock updates, I did this for awhile to no avail.
When I hit update 29 I think it is, the update right before the newest update, magic!!!! It started working and saw 4g LTE icon and had bars. Thinking that it was finally fixed I went ahead and installed the newest update which was pie thinking all was good. And yet again lost connection again.
Im getting "NO SIM CARD" on the lockscreen. Also, when I go to Network Mode I can't change from "Global" to "LTE/CDMA"
I went to Verizon got a new sim still no luck.
Any advice???
-------------------------------------------------------
-What is the dialer code or is there an app to force the network type to LTE/CDMA?
-Does anyone have a pit file for the v5 bootloader?
TLDR:; Cant get phone to connect to cell tower, says no sim card but got new sim card. Can't change the network settings from global to lte/cdma
