[Q] Bell to AT&T

Found a "deal" on a SGSII branded from Bell - I live in the south US and want to know if I throw a ROM (say Cog or a US dev. ROM) or even if I odin back to a factory ROM from an AT&T model - will this work? I cant think of something that would cause this to be an issue & I'm pretty sure it would get rid of the Bell boot up screens or any other branding but I am not 100% on that as I have never taken a out of country phone and attempted to do this before. I'm no noob with flashing but I'm also no developer either so your experience & assistance is appreciated!
(I searched & couldn't find this answered)
You don't need to replace the ROM. If the Bell phone is sim-locked, you'll need the unlock code; there's an unlocker program in one of the other forums that works with the earlier ROMs. IIRC, more recent ROMs have a different unlock mechanism that hasn't been reverse-engineered yet.
You can't replace the Bell ROM with an AT&T one, since AT&T doesn't have one -- no US carrier has released the SGS2 yet. The factory ROM will do the job; I bought a EU SGS2 back in May and have used it on AT&T since then. I get 3G & HSPA+ data at speeds up to 7 Mbps, using an old 3G SIM I've had for several years.

need help on tmo radio

Hey everyone, I got a art galaxy note last week, try to root it and flash the tmo from to work on tmo 4g.
The first I got the phone, its its already up to pics, so I root it and flashed the ics modems, blaze, kid, and last one(forgot the name)
I can able to get online but the speed is around 500k up, I'm quite upset at the moment. So I try few roms like onlyone beta 4, saurom rc 7.1, also cm9 h0tw1r3 r5 patch 1, tried *#2263# to stay at 1700hz and run hiapn to do wcdma preferred. each rom with all 3modems and still around 500k down. I'm so sad and don't know what should I try next
The best one is under saurom with kid almost reach 1m down.....
Is some had the same problem what im suffering? Please I really need some help....do I need to flash kernel in this circumstances?now is 3.0.8-perf-I717UCLE3-CL577875
PS: I'm in new York area
Please I need some assistance here guys....
there may not be any more help we can provide...
Based on the fact that you have tried all available roms, and modems. and the combinations of both.
I'm not one to give up, but based on the information you have given us, we have nothing else to offer as a suggestion.
It may very well be that your area is a particularly poor one for reception, or network.
Did you have a good speed with the stock rom and modem ?
If so, you may want to revert.......g
Agreed. You tried all the usual suspects. I quit fighting the wrong phone for the network long ago and now buy the phones for the carrier.
20% of the threads around here are about people unsuccessfully using equipment on the network it wasn't designed for.
Since your phone is unlocked, why not get an at&t month-to-month or Straightalk plan.
If you're set on t-mobile, sell or trade the phone on craigslist and get the t-mobile version.
There's no sense in being upset at this.
Thank you ranger and greg for the reply, the only reason I want to make this phone to work on tmo cause I want white other than the dark blue or black....
I know using a phone that not regularly release by the provider doesn't make sense, but just wondering is anyone having the same problem and figure out a best rom/radio or method to get it done.
actually I'm satisfy with 3g speed if it able to. ...
I think I might just give it up and sell it...=[
I have at&t but I rarely get 3g speeds even though that lying network icon is telling me 4g LTE. I don't see much improvement in their network since 3g. Can't you enjoy the phone and forget the network icon? I mean, what are you being prevented from doing?

Rezound south korea

So I am leaving Montana for south Korea soon and was pretty excited to learn that my Rezound is global capable. The only thing is I am unsure if it will work on a Korean SIM card, or how to do so. I am s-off running the first leaked ics ruu. Do I need to ruu to the global firmware? Or will any gsm capable roms work without a firmware update? Also, if there's any one out there who has been to south Korea and could give me some tips on providers to choose from it would be appreciated.

You need to install the official Global RUU, leaks can be problematic because they prevent you from getting OTAs on stock rom and may not be the latest, most stable software.
I think there have been like 2 official firmware upgrades and several leaks between what you are running and global.
You do need a GSM enabled ROM, and one that is based on the global firmware. Simplicity or Newts One XXX 5.08 may be good options for you if u want to stick with a Sense ROM.
You may still need to call Verizon re: international calling, although I wouldn't mention I was rooted.

Thanks for helping. I was a little unclear in my original post however; I actually am running Newts One XXX 5.1.0 currently (awesome by the way). What I am wondering though is this; will the fact that I am not on the global firmware mean that I will need to RUU update in order to get service with a South Korean provider. I do not plan on trying to remain with Verizon as I will be in South Korea for more than a year.

You will have to ruu to global firmware to obtain global radios to work with the global Rom

rezound in rok
I'm also heading to the rok and hoping to use my rezound. I'm on stock ics ota. I'm going to see what I get on a stock rom before I do any unofficial releases, but I expect to drop SMS capabilities or maybe data like you see in the states with a T-Mobile sim in. I arrive in Korea on the 31st so I'll update sometime late next week and let you know. I've been to Korea before and I believe we will have to go with SK Telecom as our carrier because it is the only GSM network. The other networks are cdma to the best of my knowledge. Hopefully my next update will be from my phone on a Korean network!
Rezound in South Korea update
In Korea now. I just flashed my phone from a stock OTA ICS, unrooted, s-on over to the Global RUU found on Androidpolice.
I have tried to buy just a sim card from several stores, SK, KT Olleh etc, and the stores all say that I have to go to the headquarters stores located in Seoul, Yongsan Train Station on the top floor. Apparently this is the ONLY way to get a sim for a global phone, other than having a korean national get one for you and give it to you. This weekend I will be going to the headquarters stores and getting a sim, Other problems you may run into are related to being a foreigner in Korea. They will sometimes not want to sell you a phone on a contract because you as a foreigner could disappear at any time without paying the bill. So, they will try to get you to buy prepaid. I don't want to deal with prepaid anything, but that may be a viable option to get a SIM card easily. Just buy a reallllly cheap prepaid phone that has a sim in it, pull the sim and throw it in your global enabled device. Unless you speak Korean, navigating to the headquarters and getting what you want may prove a bit difficult. Fortunately, I do speak Korean, so I will let you know how it goes.
I will update again once I actually have a Sim in my phone!
Thanks for the valuable information so far. I will be arriving there at the end of November and am looking forward to hearing more about how It's going for you there.

got a sim, no data!
Finally got a sim from KT Olleh today. The girl at the counter didn't believe me that the phone would work, but I got her to do it anyway. By the way, don't try to set up service for a phone anywhere in Korea on a weekend. They cannot activate a new phone unless its a weekday. So anyway, got it all setup and the girl sits there and plays with my phone for a while without saying anything to me. Then she tells me that the calling and texting is fine but the phone won't get a data signal. I asked her to set the APN, and she said she did. I checked it out and she had put in the KT APN as alwayson.ktfwing.com Looks right to me, and she seemed to know what she was doing for the most part. Then she started to go on about how Korea runs on CDMA for the most part and not GSM yadda yadda.
So, I have a Rezound, working for incoming and outgoing calls and text on KT Olleh, but no data signal at all. I might repost a similar message in another forum topic to see if any gurus have any advice on how to get it working. Also going to do some more research. I'm new to this but there is tons of information out there. I will post again once I have resolution or give up and buy a new phone!
PS Phones in korea can be REALLY expensive. Dropped 850 on my wifes LG phablet (optimus VU2)!!! Equivalent to the instinct in the states I think?
didn't flash twice
So, I am a phone noob, and did a lot of reading last night. Saw that most people flash rezounds twice anytime putting on new firmware etc. I think I will try that tonight and see if I pick up the data signal.
The ruu's generally need to be flashed twice. However I did not need to do so going to the global, the ruu automatically took care of everything.

website for kt olleh
Some helpful information that KT Olleh has to say about using a non-korean phone in Korea.
http://expatblog.kt.com/71
The rezound may not have the radio frequency that network uses. That would be the main problem as to why you aren't picking up data.

I am currently in Seoul and have rented an Evergreen Mobile Sim Card that works on KT Olleh's network. I am curious as to whether you were ever able to get your Rezound to work with their Data network, and if so, how? Mine works with Olleh Wifi for free but will not even recognize the 3G, despite my having changed the APN settings, and even going to the Evergreen Mobile office in Yeoksa-dong today (they said they couldn't get it to work after an hour of fiddling with it themselves).
Suggestions? Do I have to root?
Oh, and the link in your above post has expired. Could you summarize what KT said?
Thanks!

[Q] what modem do I use with CM 10.1 M3?

Hi,
I am using CM 10.1 M3. I haven't updated my modem in a long time. It is I717UCLF6. Is that the right one? How do I know which one to use?

It's kinda hard to answer which modem you need without some more details. It's also a personal preference based on where you live. Some modems/radios work better in certain areas than others. What network are you on, AT&T? I'm on AT&T and heard the latest modem for our i717 is the i717UCMB4. You can flash that one in recovery. I used it and it works but for some reason the i717UCLD3 modem is working better for me. I got that modem when I used odin to install this rom, then flashing my favorite rom on top of it. Some people say the UCLF6 modem works better for them. You can get that one here and flash thru your recovery. Sorry I can't find the i717UCLD3 flashable zip. Maybe someone else has a link so you can flash between all 3 and see what works out best for ya.
No need to do any modem flashing. LF6 is the latest and greatest modem available.
Updating.....AT&T released 4.1.2 and a new baseband/modem which can be found here http://forum.xda-developers.com/showthread.php?t=2261713 and is flashable from custom recovery.
I'm testing out a possible switch to T-Mobile. Had AT&T unlock my phone today and got a prepaid T-Mobile SIM in it. I'm getting H+ (LTE?) speeds while doing data transfer and then it drops back to 3G when data isn't being used heavily. I'm on UCLF6. Although I've had this phone for a year, installed tons of ROMs, compiled my own kernel, etc. I'm a noob when it comes to modems and have just used whatever worked. What's the advantage of using a "T-Mobile" modem if UCLF6 seems to be working on T-Mobile anyways? Do you get more speed out of it?
I don't want to lose AT&T compatibility yet as I just got the prepaid T-Mo to test out (been getting crappy reception with AT&T at work and tired of the expensive plan of minutes I don't use). If T-Mo improves my speeds at work I'll probably just pay to cancel my AT&T contract and transfer my number, but for now I'm just testing.
Well I am not sure about the baseband/modem issues on T-Mobile but most important would be the GSM Bands/LTE are compatible. As some AT&T phones don't support 3G/LTE frequencys T-Mobile use. If you are using a prepaid SIM it may not even support LTE for example Straight Talk on AT&T supposedly will only use HSPA+ .

[Q] Custom ROMs and Internation Travel?

The wife just upgraded to an VZW S4 and so far loves it. Thank the gods as she was coming from a problematic Incredible 2. We do some internation travel and the question is How friendly are custom ROMs when it comes to travelling in other countries? We took a trip to Belize with the DInc2 running Virtuous Affinity and then another to Norway and neither trip did the phone work correctly, but I'm not sure if this was a ROM issue or something else.
I've tried to Google this question, but hadn't found an answer. Perhaps I'm wording it wrong.
Should we just stick with the stock ROM since international service is a must? Rooting isn't a must, but the deciding factor is the ability to tether which can be done rooted or unrooted so sticking with stock shouldn't be an issue.
Im here for the same question. Any one else have an idea if custom roms still work with international travel and Verizon international plans?
I am currently running CleanRom 1.6.5 and just got back from Italy. I used a sim card from over there, popped it in, and an hour later was up and running, data included. I used the data the entire time, and made a couple calls. It was only $26 for the sim and the service, and may be a better/cheaper option for you. I can't say about the VZW International service, but if that worked, I don't see why it wouldn't. Hope this helps.
