Im Active duty military so i end up where every they send me. I had to purchase a local phone since i will be in korea for the next year. I chose the Samsung Galaxy Nexus as my phone. i wanted to know if i can still root this phone and flash a custom rom with out messing up the phone.
The model Number is SHW-M420K.
Its running ISC 4.0.1.
The boot loader says the Board name: tuna Rev 9.
The base band is: M420KRKK7.
Kernel Version is: [email protected] #1.
Build Number ITL41F.M420KREK24.
Please Let me Know Thank You
This is not a stupid question.
The simple answer is that the M420K is the KT Telecom version of the HSPA+ Galaxy Nexus, internationally known as I9250 but has bigger battery. So, yes. You can do all of the above.

Almost the same question though it might be repetitive or stupid. I have that HSPA+(3G) version of KT Telecom GN coming a few days later. Is that the GSM GNex? That is, will all the applications, custom ROMs and firmwares for GSM version in XDA going to work with my phone? I checked out both forums for GSM and CDMA version since all Korean phones use CDMA network, but it seemed like CDMA forum here was all about LTE version serviced by Verizon.

Basically, the Korean Galaxy Nexus is not CDMA. It is GSM and works in Korea using the 3G WCDMA. You can confirm this by switching off the 3G in the Wireless Settings "Use only 2G networks" and you will see that you lose the phone signal and can't make any calls.

would a pentaband GSM model work in Korea if brought from the u.s./Europe?
If so, how difficult is it to get a prepaid or temporary sim card when visiting?

Prepaid or temporary sim card is pretty hard to come by cheaply if you want data.
Yes. Forget prepaid sim if you want 3G data.
Getting set up with a phone in Korea is a real pain for expats.

Dear Friends,
I am currently on Verizon Network and planning to upgrade my phone to Samsung Galaxy Nexus.
The problem is I am leaving to India in a couple of weeks and I will be staying in India for 3 months. During these 3 months I want to use Nexus with an Indian CDMA carrier.
1)My question is - can i use the Nexus with an Indian Carrier? If yes I guess i need to unlock my device.
2)Can someone help me with the information of how to unlock the Galaxy Nexus. It would be wonderful if someone can guide me with this.
3)If I unlock the phone will I have any problem using my phone with Verizon when I return to US after 3 months?
Really appreciate your help folks

Well that's not true. It is possible, but not plausible. It requires you to completely re-flash the phone to a different carrier's network, and then have the carrier accept a device with an ESN not in their system, which at best is a long-shot combination.
So, it could work, but it probably won't. And it isn't really worth the hassle.

I was under the same impression.
OP, you should pick up a GSM phone for your travels and save yourself the trouble. Leave your Nexus in a safe place at home with the battery left at about 65% charge and the phone off
thank you very much guys for your replies
there is cdma network in india- Reliance Communications
Just trade it for a gsm one
Sent from my Galaxy Nexus using XDA
To be clear - Verizon stores even the CDMA subscriber information on the SIM for LTE phones. So if there is a provider in India that uses CDMA SIM cards (rare, but I know they use them in China) you might be able to get this working.
Or you could get a GSM/HSPA phone to use on your trip

Sim tray maybe but the vzw one is cdma and the GSM one is...well..GSM.
Different technologies! Not compatible.
I have the Verizon phone and yes it does have a SIM card but it uses different radios. Verizon uses CDMA/LTE and T-Mobile uses GSM so you can put whatever SIM card you want in there but since it uses different radios it won't physically be able to talk to T-Mobile (or any GSM carrier's towers)
btw, what happen if you travel away USA in a country without CDMA?.
At least, the CDMA iPhone have a simcard tray but it's locked until your operator wants.

Starting with Verizon's 4G LTE phones they all require SIM cards. They were also used in 3G global phones (my old blackberry and droid pro had them) but the CDMA Galaxy Nexus isn't global so you'd just SOL.
well.
nope. it won't work cause it's not CDMA...

@[email protected] can't believe people are asking this question. The phone has been out for over 3 months now.
Besides, the SIM card slot is specifically for LTE... as in, the SIM card is an LTE SIM card. LTE, not HSPA+.
I can only think, because the AT&T (HSPA+) model would be more prolific among sellers, that you'll have a better time finding a better price than a Verizon (LTE) one.

Then you have no service. Grab a cheap GSM phone and pre-paid SIM.
Try the yellow or the sky blue Galaxy Nexus. Those ones will work on both Verizon and T-Mobile.

Back when verizon did both GSM and CDMA I had a verizon phone that I got to work on tmobile. I think it might have been a windows phone, honestly it was a while ago. I had to pay for a network unlock code and patch a radio or something....anyway, just wanted to say that it is in fact possible. My phone did brick in about two months, but that might have been from getting it wet...anyway...Good luck!

Total non sequitur. The phone in question must have been an old "world phone". The Verizon Galaxy Nexus never had any GSM radio whatsoever.

For the CDMA GNex you would need either a CDMA or neutral carrier/MVNO (such as StraightTalk, Tracfone, etc.). I have a CDMA ex-VZW GNex (now running Unlegacy-Android 7.1) that I am taking to Tracfone (replacing a Tracfone feature phone) because Tracfone uses a mix of carrier towers (depending on location, either T-Mobile or VZW). My current feature phone uses T-Mobile towers - because I am bringing a CDMA phone under BYOP, I have to ask the carrier (Tracfone, in this case) to create a custom SIM Kit for the brought phone, and thus have to communicate the IMEI and MEID of the incoming phone (this information is in the phone under Settings). Yes - this also applies to lifeline feature phones supplied by Tracfone/Safelink (if Safelink supplied the phone, Tracfone is your MVNO). If you want a GSM version of the Galaxy Nexus, you would want the maguro (the Galaxy Nexus in AT&T Mobility or T-Mobile guise); because GSM is more popular overseas, they tend to get exported compared to CDMA or W-CDMA (Verizon or Sprint, respectively).

Until vzw goes to VoIP in the next few years the only thing the sim supports is 4g data. Because lte is a gsm based network, sim cards are needed. Nothing else in a Verizon phone used the sim so no you would not receive full service using a vzw sim. Not sure if you'd receive data or not but I'm betting no
Verizon uses CDMA for voice, and CDMA/LTE for data. Not only are the LTE frequencies incompatible, but CDMA is incompatible as well. So no, the Note 2 will not work AT ALL on Verizon.
Also to note, Verizon will only let you activate VERIZON BRANDED phones on their network. You can't buy unlocked phones and use them like a GSM carrier (AT&T, T-Mobile in the US) would. Sprint is the same way.

Ok, so if I purchased a Verizon Galaxy Note 2, and rooted it, I could then use AT&T and later if I finally want to switch over to Verizon, I could... If I am mistaken about this, please let me know. Because I am trying to get a Galaxy Note 2 that will work with both GSM carriers and also work with Verizon when/if I choose to switch.
No. Verizon and AT&T phones/networks are not compatible with each other at all.

This does not exist on ANY Note 2 on earth. Possible with *SOME* other phones, but not any Samsungs, and definitely more trouble than it's worth. NONE will be LTE compatible though. 99% of the GSM compatible phones on Verizon are locked on only work internationally, and will not work AT ALL for the US.

Any new Verizon phones can work on any GSM HSPA+ network with some trickery or are unlocked out the box. Some phones work on At&T and T-mobile while others only work with carriers outside the U.S. YMMV.

I think you can get the Verizon S3 to work on AT&T (calls/text/edge data). I know you can do that on T-Mobile. But you won't be able to get the AT&T S3 to work on Verizon for two reasons;
1) The radio would need to be hacked to enable the CDMA radio, and the information needed to hack the radio is not available. The US variants all received the same radio chip, just some of the frequencies are turned off. For instance, the AT&T S3 wasn't able to get the t-mobile AWS band working until the guy working for t-mobile released some radio files. The AT&T/T-Mo S3s have the CDMA radio, but it's not enabled
2) Verizon won't allow the phone on the network, as the IMEI is not registered on their network. This is probably the most important reason. You would need to spoof the IMEI from another verizon phone, which is not something that can be discussed here.
You are better off switching with someone who has a Verizon S3, that wants an AT&T S3.

It will work with T-Mobile because it's a GSM network. The radio can't be hacked. It's a limitation of the hardware itself. It's 2 completely different pieces of hardware.
The sim card on Verizon phones is ONLY used to access Verizon's LTE, without that simcard you'd have regular 4G only on a Verizon phone. That sim card/or phones acts in no way possible as GSM accessible.
So no it will NEVER work regardless of what you do.
And don't fall for ads on the internet about any Verizon,Sprint, or any CDMA phone to work on GSM networks.

This is not entirely true for all Verizon phones. The DNA, S4, Note 2, LG G2 (among others) are sim-unlocked out of the box, and will work with AT&T/T-Mobile (the note 2 requires some hacking in order to add the APN settings). Also, as I recall, if I took the sim card out of my GNex and DNA, I did not have service. It would only allow for emergency calls. No talk/text/2G/3G.
For the Galaxy Nexus, the phone is 100% guaranteed to not work on any GSM network.

Read the first sentence
"Only to get Verizon's LTE"
Unlocked phones work "globally"
Which means you'd get Voice and EDGE/3G at the most from other GSM networks, given you've provided the correct APNs. Locked phones, which carry that sim card for Verizon's LTE ONLY. Either way only a few phones will work. The rest are useless.

No. They use the same hardware. Msm8960. It should support GSM CDMA WCDMA LTE and Td-scdma. Almost all the network. It's mostly because of the lock of the radio/nv.
Remember, the op is asking if he can use an at&t galaxy s3 on Verizon. It's not going to work.

i can verify that i an running AT&T straight talk service on my sch-i535 (Verizon Galaxy s3)
I have had success using a Verizon sg3 mother board on att's network although I was only able to get 2g. What I did was rooted phone, ran region unlock app, next I let the phone sit for a day, then a did a factory reset from the phones menu not custom recovery. Then when going through the set up wizard it prompted me to insert sim card then it said it was not an approved sim and gave options to continue or finish, selected finish, said complete and about 3-5 mins after booting up I got signal bars and phone was working. Although the hardware used are different these are dual band phones.
