Only LTE works on V300L - LG V30 Questions & Answers

Hello guys,
Quite the unexpected happened with this newly received phone. My country has at least 2 WCDMA and GSM bands in common with Korean carriers, but my phone seems only able to connect to LTE (even when forcing 3G or 2G in the secret menu).
I'm not sure whether this fits into the broader "no signal" issue that forces people to root their phones in order to connect to any network.
+ I would've thought that flashing the radio/modem would be enough to solve such an issue, but I'm likely too naive.
Any missed info about this LTE-only problem?
Thank you very much for your assistance!

Network realted question. Please help!

Howzit guys,
I brought a HTC Aria in the USA on AT&T network. I came back to SA and rooted my phone put Android v2.2 on (phone came with v2.1) thinking that would unlock the phone, but it didn't. I ended up looking on the net for a website that I could get an unlock code for my phone. Long story short, I found one, paid for it and it worked. I'm using the phone on Vodacom no matter what I do I can't get 3G or HSDPA to work, only GPRS. HSDPA and 3G work fine in the states.
After doing some research I noticed that in the Mobile Network settings on the phone there is 3 options under Network Mode:
1. WCDMA only
2. GSM only
3.GSM / WCDMA auto
Now from what I've seen I need to use WCDMA to get the 3G / HSDPA to work, but when I select option 1. I don't get any signal and then phone eventually switches to GSM automatically. I was at work on the weekend helping a customer with her laptop and she had a 8•ta 3G modem, and 8•ta 3G modems are currently running off of MTN's network I was told this by an 8•ta technician and I noticed when connecting the modem it said something regarding WCDMA.
So now my question, if I change to MTN do you think I will be able to use 3G / HSDPA on my phone?
Any info regarding this will be greatly appreciated.
Thanks
The American version of the Aria uses different 3G frequencies (because that's what AT&T uses), so unfortunately your phone will not work with 3G in South Africa. There is a different version of the Aria (called Gratia in most regions) that is the exact same phone except it supports the correct 3G frequencies for your country, but there's nothing you can do with the phone you have now to make it work.

Galaxy S2 HD LTE (SHV-e120s)

Hi guys
I recently got one of these shipped over to Australia. Now I've encountered a few network issues I'd like help to resolve.
1. I think the only HSDPA/UMTS bands available are only 900/2100MHz. That means I can't get access to Telstra's Next G Network as it runs on 850MHz. Unfortunately I can't get access to the service mode at all and I've also downloaded the network app from the android market to see if I can change the band that way, but that doesn't help either - the app just crashes. I guess there's not much I can do there.
2. According to all the sites I've seen about the specs for the phone - LTE bands supported are 800/1800/2600MHz. But I can't seem to get on Telstra's LTE in sydney. The phone assumes that even with a Telstra sim, I'm on roaming with SK Telecom and it states that 4G roaming is now available. The aforementioned network app is set to "GSM/WCDMA/LTE auto" - yet no LTE!
Perhaps I could flash to another ROM? but I'm not sure which would be applicable? The LG Nitro HD has the closest specs in my opinion. Any help would be greatly appreciated.

1. usually, bands are hardware limited. Meaning if you don't receive a particular band, you probably won't ever be able to.
2. what bands does Telstra's LTE operate on? #1 applies here too. If the LTE antenna in the phone doesn't receive the frequency your operator is transmitting on, there's not much you can do.
And in your "Perhaps", why would you even consider flashing a ROM for a completely different phone to yours???? (unless you WANTED to end up with a paperweight)
EDIT: Look at this thread. Specifically what's in post 2, which reads "So it doesn't matter where you buy the phone from, it will work on Telstra unless you go buy the korean version or something." Just googling your model number (SHV-E120S), it looks like that IS a Korean version of the phone. The fact that you say it says something about roaming for SK Telecom (a South Korean carrier) seems to support that.
EDIT 2: a quick google for the SHV-E120S turns up this page, which says the phone is for networks voice GSM900, GSM1800, GSM1900, data (HSPA+) UMTS900, UMTS2100, and LTE frequencies LTE 800, LTE 1800, LTE 2600.
According to Telstra's wikipedia page, HSPA on Telstra is UMTS850 and UMTS2100, and LTE is LTE1800. So you won't get full support on all of Telstra's bands with that model of phone.
It looks like you'll prob be stuck with 3G nextwork if you use this phone in AUS.
Remember: DO NOT try to flash ROMs that is not for your phone. I've tried this one time and ended up hard-bricking my phone. NEVER DO THIS!

Ive read a number of XDA sites where people flash and install new modems with different bands. Woudl it be possible to install a 850MHz modem into the above phone?

Um, no. No flash will ever address a hardware limitation.

hello guys,
i had the same problem using it in Albania and i find somewhere that you can access the hidden menu by entering at the dial pad the code: 319712358 pass:996412. then at "network settings" you can select GSM modes.
i'm still facing some problem with the calls but overall it's working.
hope it helps.
how could i activate or turn the 3g to 4g? im from PHI

if you are on JB (4.1.2) it should work or you can even try an app from google play "SKTHiddenMenu", practically does the same thing.
hmm does this unit has many problem??
i would like to root my phone but i still can't find the right apps to use

yes im on JB 4.1.2. but i'd stuck on it. after i enter the password? it doesn't happen or it didnt went through. i already try to download the SKTHiddenMenu. when i tap the network it doesnt happen. why else can i do to activate the 4G on this phone?
oh im sorry maybe thats why it not work because im using shv e 120L not 120s im sorry.
so now do you know the password for shv e 120L or its the same with shv e 120s?

Best setup for UK ONE on AT&T

So I love my HTC ONE.... Fantastic phone.. No question about it.
As I posted else where I have the UK model and I am on AT&T in the USA. It's working, but the HSDPA and 3G is bouncing around quite a bit and it jumps to E really quickly. And it loses the signal quickly in low signal areas. More than any other phone. If I switch the network to GSM, I have full signal almost everywhere.... But no data bandwidth.
It was suggested that I might need to look at my setup.
So here is what I have.
I have a STD LTE data plan
I have a STD sim that work on all my other LTE enabled phones
My APN is Called Phone and has the same setting as I find on the forum for a 4G setup...ie it is NOT the wap and cingular setup.
I have selected WCDMA and GSM networks (I know the phone is not compatible with AT&T LTE bands), but it acted the same way even when it was on the default GSM WCDMA and LTE Auto setting.
Does anyone know else I should check or change?
PS. I will likely buy the developer model, or the AT&T model as soon as it is available... this phone is that good!!!
Thanks for your help.
Nick
PS. I will be in Korea next week, so I am curious how the LTE will function there.... I will let you know. I think they have the 2600 band on one provider and that overlaps with the UK bands

GT-i9100 network trouble!!

My brand new GT-i9100 is barely usable. I've spent the last week wrestling with it (bought it new from ebay) to get it to work, but I'm at my wit's end. Any help would be greatly appreciated. Here's the problem:
My Galaxy S 2 (now rooted and currently running SlimRom) partially or completely loses cellular signal about 60% of the time, often in places where I know there is reception. I'm using Telus' network in Canada. It will lose data, lose ability to make or receive calls, and fail to send text messages. The indication of signal loss is not clear, IE it will say "emergency calls only", "no service available", or even say I have service but I really don't. However the cutting out seems to occur consistently depending on where I am located. For example I seem to get OK signal at my house, but zero at my friend's house. I know it's not the network in this case, since my friend is also on Telus and they get fine reception. I've done some testing and here are some possible causes that I can think of:
network cold spot - No, see example above. It also cuts out in urban populated areas where the signal is strong
phone compatibility - unlikely, since Bell offered the i9100M, which I'm led to believe is physically identical to the normal i9100, and Bell and Telus operate over the same frequencies. Also when it does get signal it can transmit data fine
SIM card - No. The first thing I did when I discovered this problem was get a new SIM card. Nothing changed
SlimRom - No. The phone was acting like this out of the box with the stock image.
Radio firmware - Unlikely. I've flashed at least 6 different firmwares, including KG6, KH3, LQ6, LP6, KI4, and even LD3, which I believe is the firmware the Canadian i9100-M ships with, so would logically work fine. The carrier for that was Bell, and I believe Bell and Telus operate on the same frequencies
a hardware defect in the design of the phone or the antenna itself - the last possible option I can think of. I hope it's not this, because then I would have to undo all the modifications I've done in an attempt to fix my phone, and pray the seller accepts the return
Please, if anyone could offer any assistance that would be great.
Telus frequencies:
2G
CDMA 850/1900
EVDO 850/1900

Well.. I think you got one of the Korean ones.. There is someone in China or Korea, or who knows maybe Samsung who is taking the SHW-M250S, a horrid Korean version of the S2 and changing the housing and software to make them look as the GT-I9100. Even the back labels say GT-I9100 and the software itself.. however, you can tell them apart because they are way lighter and very flimsy and also because the SIM Card tray is different from the one on the original GT-I9100.
So, I know it's very late but the problem is not you, is the phone. It might look brand new, but it is not compatible with networks in the US and many countries as Korea seems to use a different network standard. I was not able to get any data working on this model when I was in the Dominican Republic. I recently got a few of them in a lot of devices I bought for resale after I moved to the US and I couldn't get any of the 14 phones I got to connect to cellular. I decided to strip them off for parts.

[Q] Nexus 9 LTE on Vodafone UK doesn't get LTE

Hi,
There's a thread going on on the Vodafone UK forums about the Nexus 9 LTE not connecting to Vodafone UK on anything higher than 3G. I don't think this is very well known as the LTE version isn't as popular as the Wifi version, and then there are multiple mobile operators to choose from, so this might not affect many people.
Basically, a known working Vodafone 4G SIM in a known 4G coverage area will only establish 3G, never H, H+ or LTE/4G - this has been tested with multiple devices (I've got two here now) and multiple SIM's. The devices are unlocked, Vodafone don't require IMEI registration or anything like that. It should just be a case of putting the SIM's in. I've done all the checks I can think of (SIM's in another device - they get 4G, other operators SIM's in the device get 4G) etc.
Vodafone use LTE band 20 (and band 7 in a very few locations for LTE-A). Band 20 is known to work on the radios in the device because the same devices can connect to EE, who also use LTE band 20.
HTC are not interested as they say its a network problem, the device can register on EE and advised me to contact Vodafone.
Vodafone are saying its an unsupported device, I didn't buy it from them and don't really care, their first line support said the SIM is registering on their GSM network but never registers on the 4G network hence no coverage. After a conversation with second line support I was told that the device is trying to register on band 8 (900MHz) rather than band 20 (800MHz) which means that its a software/hardware problem - I'm a little bit dubious about this as how would they know unless it was negotiated by the SIM or something as their equipment uses 800MHz... ? I think he was basically lying to me to fob me off.
Google don't even have a way of contacting them about the device.
So as a consumer I'm stuck! Is there anyway I can debug the device myself? Can I see what bands are being used at different points in he SIM registering process with any software? Basically - any help or advice at all guys. It sucks to spend a load of cash on a device that half works, but what REALLY sucks is having no way to escalate a clear cut problem because there are so many companies involved!
Thanks in advance!
