Galaxy S2 HD LTE (SHV-e120s) - Galaxy S II Q&A, Help & Troubleshooting

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.

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.

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?
