Tez, did you get the update from a Tmobile store? Or, did you install one of the rooted GB ROMs? Just wondering how you retained S-OFF after the update... Thanks!

A few people have reported keeping S = Off even after getting the official OTA/TmobileStore update. They still lose their SuperUser access though so they're pretty much unrooted for most intents and purposes.
As far as I can tell, keeping S=off after the update seems to be random. Either that it or it has something to do with the rooting method originally used. I feel like the gfree method is more likely to let you retain due to the fact that it's a more invasive kind of root(rewrites your emmc chip) than the root.sh method. Then again, that's just speculation on my part. I haven't seen any threads actually trying to determine what the main factor in that is so yea...
I guess the best way to figure out what causes it would be to have anyone who got the update after they were rooted report what method they used to root their phone. If my speculation is correct, then only the people who rooted with gfree would have kept S=off after they updated, and anyone who used root.sh would have lost it.
Regardless though, until someone figures out how to root the stock 2.3.4 anyone with the update is in the same boat, regardless of whether S=off/on.

And to answer your question Tez: No, downgrading to Froyo still seems to be the only possible method of rooting and sim unlocking once you have the update. Unless a development occurred that I didn't hear about it, in which case anyone who knows how should feel free to correct me.

I used the gfree to root before I got the update afterwards I went and got the update after my phone started messing up after a flashing problem to my surprised I stilled.had s off after the official update I got at the t mobile store also when I put the other sim in my phone it indeed did show cincinnati bell were it would show t mobile on the lock and notification screen only thing I thing I didn't get to test was sending and receiving calls and data speed because I didn't have any talk / air time or internet service at the time our now lol but anyways.the sim does work so far

Hmm so maybe the sim unlock actually sticks even after the update. That's pretty cool. I'm guessing that's another one of those things that gets written directly onto the phone's hardware or something and is unaffected by the update.
Wish we could get a dev or someone more experienced in here to give us their opinion.

Yes I think so also my mother has a cincinnati 3g sim card also imma try it out and see if the 3g sign, finally shows

[Q] way to mcc unlock mytouch g4

glacier 2.2.1 t-mobil mytouch 4g
temp rooted visionary+gfree_2
Is there way to unlock mcc to use this phone in USA and in Europa?
I will work my self in this direction:
http://forum.xda-developers.com/showthread.php?t=858996
But i wonder how MCC fits in to all this if so?

Deep in thought about this....ideas?
I actually wish I could post on that thread, but alas I don't have the power....
I have rooted my MT4G twice now after restoring to stock in order to use gfree to unlock it.
Eng S-off and CID is 11111111 but when I put a AT&T sim in there is no service. I'm a pretty savvy dude, and can't find anything on how to correct the issue.
I would love some advice even tho this isn't the right thread .... lurking has cost me the ability to post where I need to

gfree unlocks the phone. mcc/mnc/cid/whatever.
If there is no AT&T service - most probably you have only UMTS (3G) service at that spot, and the UMTS bands are incompatible with MT4G.

I was digging through the radio threads thinking it was something of that nature.
currently on the stock T-Mob radio....suggestions?
and thank you for the reply

Radios won't help, they don't change the frequency support. I don't have any good suggestions...

I don't know much about radios....seemed people were getting better service by changing them. Guess changing the radio doesn't allow for better reception of other towers, based on what you said. Thanks.
I think that in the unlocking process I may have hard locked it to Tmob. Everything I have found online says that a foreign sim will bring up the option for unlock code, but mine doesn't and never did.
I'll keep digging and post if I find any answers.

Radios will affect the signal and its strength, and may change battery life overall, it doesn't relate to the phone's frequencies though.

Thanks Ace....
I did try doing *#*#4636#*#* and switching to GSM only which on Tmob gave me Edge only even at home, but it still didn't read the AT&T sim, and when trying to set the APN on the Tmob sim it will save but not on the AT&T one.
Do you know of a ROM that gels with using 2G only and allows the APN to stick?

If you're using the stock mysense rom, ginger or froyo, try another one like CM or Miui. And if those don't read the aim, try a sense rom instead. It should stick though, when you save the apn, perhaps you should also try another at&t sim card, just to be sure. I'm wondering if the CID thing from gfree is related to this or not, I've never unlocked my phone, but it might be best to use the unlock, if you can't get the sim to work properly. Gfree and its CID method could be causing some underlying problem with the reader.

Just to update my attempts in case someone runs into the same issue....
Tried a couple MIUI ROM's (not a fan of them), CM7, several Royal ROM's (a couple stuck in their Android boot loop), Sense ROM's, and stock FROYO and GB....
going back to the stock ROM's - I flashed after formatting and wiping and the IMG did bring the phone to stock, but never turned S=ON. Today I'll be doing manual unroot to get S=ON and then reflashing the stock ROM's to see if I can get the phone to ask for a network unlock code. If I can get that I'll buy a code and run with it. I'm thinking that the Gfree method of unlocking isn't 100% compatible with the MT4G. IMO
Having an issue with VISIONary ATM on GB, but I'll keep you posted. This may end up being very helpful to other MT4G owners down the road. Thanks for the input guys.

If you flashed the ota, then you'll have to downgrade to froyo first. Since the stock gb can't be rooted yet, w/o downgrading first.

Yeah face slap after the post I realized it won't root on GB....lol moment of idiocy.
I flashed the stock froyo and still S=OFF persists.
I tried the unroot sh method listed HERE
No dice. S=OFF still there. I have a second MT4G that I never rooted, so I'm having a friend bring it to me so I can do some additional testing to see what the problem is. Unfortunately I dropped T-Mobile contract plan so there won't be any warranty swaps if gfree did create some gross underlying issue that can't be undone.

Ok so logical deduction says it has to be the SIM card....
Putting the AT&T SIM in the stock never touched phone, the phone sees there is a SIM card, but doesn't do anything about it.
My rooted phone acted as if there was no SIM, but the unrooted one just didn't do anything...simply said there was no service, and the phone didn't register that there was a phone number associated with the SIM.
IDK, maybe I'm way over analyzing this all, but I'll get over to AT&T and see about getting a new SIM to try that.

Sorry for repeated postings....
Ok, so new development for those who have the idea of using AT&T prepaid on a spiffy MT4G the issue IS the SIM
I was reading on AT&T's forums and it seems that they are hip to our MO and made new SIM's that don't work in regular phones. The gold contact area is smaller and so the MT4G doesn't see it.
I'm hoping that I can get someone cool at the store to setup a normal SIM for me to test. I'll post an update once I have gone to the store.

Normally it would be on, after flashing the stock/unrooted ota. But, why do you need it to be S-ON anyway? Are you planning on selling it?

Not selling, just curious as to why it happened to stay S=OFF
Old full sized SIM cards can no longer be gotten through the store, searching online. Seems AT&T wants to stop people from putting their SIM cards in unlocked phones. I was told approx 2 months ago they forced the stores to switch to new SIMs with smaller contact area. This is going to make things difficult for those who want to use unlocked phones on AT&T.

What rom did you flash, to try and get S-ON? If you use the one w/ the new hboot and radio it should be on again.

I flashed the stock froyo PD15IMG file and the OTA, which either should have returned to S=ON, but didn't. I'm not overly concerned with the fact that it stayed S=ON, but after multiple attempts and staying S=OFF makes you wonder.
It did take it out of ENG mode and back to SHIP
I'm trying to find an older SIM which is proving to be more difficult than anticipated. I would have though ebay and Amazon would have them, but I'm not having much luck.

Your S-OFF most probably stays because you were rooted with gfree, and you have the security flag set to off. No amount of flashing will turn it back on.
Run gfree again, with the right switches, to turn the security back to on. Use any rooted Froyo ROM for that. Then flash PD15IMG, and you'll be S-ON.

I had a feeling that gfree had done a better job with a true root than the VISIONary way I had done it originally. Thanks for confirming that. Still trying to track down an older AT&T SIM card to test the unlock. Nothing is ever easy, lol

how can I update my note without a sim card

Hello,
Im a verizon customer (only carrier here that actually works and have GREAT coverage). But I wanted a device that I could use to remote my servers that had a great screen and processing power. So as you can probably tell, i flipped when I saw the note and picked up one right away.
But now my problem. I see that there are updates out and such, but I don't have an ATT account. When I go to update the note it just tells me that I don't have a sim card. How can I update my device without a sim card.
I tried to look this up, but didn't get far (I guess most people here have an ATT account or a GSM carrier). So is there anything I can do to update my Note. (I purchase an unlocked one, if that helps any).
Thanks in advance

Ah buy pay as you go sim or borrow one.

Did you try inserting the sim when the phone is off ? When I inserted the sim, the phone was on and it would not recognize the sim even after reboot.

How do you fix your issue?

Did you use a sim cutter or did you use scissors ?
The sim needs to be completely flush on the tray.
Remove the sim and turn off the phone. Insert it, and power it on...

[Q] using AT&T provided unlock code...

After fighting with AT&T on the phone for almost a month due to (in my opinion) unfair policy changes, I got them to provide me with unlock codes for my and my wife's phones. I want to make use of them asap and put this matter to rest. Unfortunately, the AT&T instructions say to use the codes i have to insert a non-AT&T sim card to force the phone to prompt me for code entry. At this time I do not have a non-AT&T sim. Is there any way to get to the unlock pin screen without having a "foreign" sim card on hand?
Any help would be greatly appreciated.
Thank you.

Also, does having this unlock code mean I am unlocking the bootloader or is this *just* a sim unlock?
I am considering experimenting with the 'nightly' for CM 10.2. I have CM 10.2 on a Note 8.0 and CM 9 on an original Galaxy Tab 7" already and i like it a lot.
Thanks again.

Won't touch the boot loader at all. That'll just be a Sim unlock.

Research it. Then research it some more. Research it until you are comfortable doing it yourself. Don't let someone bully and say you might mess up your phone. You could mess up your phone by dropping it in your sink among other things. But doing this is quite simple. Follow the steps here is even a youtube video to do it. If you have any questions ask away. Some ppl are jerks and say it was answered somewhere else you should of found it elsewhere. When all posts inevitably get buried under mounds and mounds of new posts. Remember you only fail if you stop trying.

You could also head to t-mobile site and get a free SIM, I think they still are giving them away, not sure. I was able to get two free SIMs 5 days ago.

And this guy ^^^ isn't going to fix your phone for you if it does screw up. The "free" unlock method works for some and does not for others. I completely agree with the research until your eyes fall out part, but, in this, case, it still might not help you. So, basically, if you try the "free' unlock method it might work, it might not, and it might mess your phone up. Unfortunately, you won't know until you try. I would just go to your local mall or T-mobile store and get a cheap pre-paid sim card that you can use in your and your wife's phone. Don't listen to people that think something will work for everyone just because it worked for them, especially when it is proven to not be the case. Good luck.

I walked into a tmo store and sled if they had an activated micro Sim so I could test my phones unlock status. I told them I was thinking of switching, but needed to verify if my s4 was unlocked (I used the service menu method).

Would you mind sharing how you got them to unlock your phone, I have been trying for a while now without any success.

When I had my old smartphone, I called att and told them I'd be visiting my sister in London, and that I'd want to use prepaid SIM cards, as it would be cheaper than international rates. They had no problem unlocking it (galaxy s).

Lol it doesn't "mess up" your phone. *sigh* stop scaring the kiddies

Usually no prompt means the phone isn't actually locked. There's a ton of instances when a network simply missed a handset and failed to lock it. For anyone I'd say test your phone first. Make sure it is locked before going through the process of unlocking it.
Also, this works on a number of older Samsung's, not too sure if it'll work on newer models, but you can type a command that targets the network lock, which is #0111*code# - you simply replace "code" with the code AT&T or anyone else gives you and it should unlock the phone. Someone might be able to confirm this as possible or not for the newer Samsung's?

I tried the traveling story. That does not work anymore. CS, including supervisor refused.
