[Q] Sony Xperia TL [LT30at] - Need to free it from AT&T - General Questions and Answers

Hello Community!!
Noobiest noob here. Please forgive my ignorance.
Sony Xperia TL [LT30at] AT & T phone.
Android version: 4.1.2
Build: 9.1.F.1.120
Here is my issue:
I now need to use this phone in India with a different network provider, but i don't want to spend money on unlocking the phone for a new sim card. I read a bit about flashing a custom ROM and watched Jeremy Phan's video: "3 ways to root your (xperia) android: tool kits, kernel flashing, recovery"
I installed sony's pc companion and update service, i also installed the flash tool on my machine.
a) will flashing the phone do the trick?
b) if so i'm having a tough time finding the right firmware for this phone. Please link me to a robust and hazel free firmware for my phone.
thanks a ton

Hi Micky,
You cant unlock your phone (remove SIM lock) from the operator by reflashing it. You will need an unlock code for that. A legal way is to obtain it from AT&T if your contract is ended, the other one is to buy it, e.g. on eBay. Once you'll get it, just enter a simple key combination to get into service menu, go to appropriate menu item and enter that code there, after that your phone is unlocked, no reflash needed.
Hope that helps.

Hi summer,
Thanks a lot for your insight. I've been searching all the corners of the internet for a while now, with a vengance I think it should be time to drop those efforts.
Please bear with me, i'm trying to think out loud here - Is there no way i can tweak the phone to accept any sim card? Like by disabling a few settings or hard coding some part after gaining root access?
Buying an unlock code is not an option for me at this point, and i don't want to use the phone just to check email and take pictures
many thanks

SIM lock information is not stored somewhere in firmware, which you can access by gaining root permissions. I assume there may be some tricks similar to Turbo SIM in iPhone where you can emulate the correct SIM, but its definitely not worth it.

Bypass Activation/ Unlock Cellphone: LG VS740

I got this phone, I'm not on the Verizon network as the phone is. Phone was working great w/ wifi bluetooth etc.... then I reset the phone back to factory defaults. Now it is asking to activate the phone etc... when I boot up the phone.
Some other people suggest that it is a mere process of tracking down the unlock codes.
wanted to know if there is anything else that comes to mind, like a new OS, boot loader or something?
Any help is appriciated
Guess nobody got any ideas of how I can use this phone as a PDA?
at the start up i get the android activation w/ verizon, which I would just like to bypass and use as a pda
I don't know that phone, but if it was already rooted & has a custom recovery image on it, try searching for a guide to installing a generic custom ROM via recovery. That /might/ avoid the registration step, if it was Verizon specific, rather than specific to the device model.
Why don't you want to use the device as a phone? Seems a shame not to.

1. I am a Canada WindMobile XT720 owner, from my knowledge if u have an account with them for 3months they gives out free unlock codes.
2. Root won't/can't give u 2.2, be sure root and firmware is apple and orange. Root is a permission level, such as Administrater/Guest on Windows (linux call highest permission level ROOT).
3. Android 2.2 is not coming to non-Korean XT720, however, some individuals are working on getting a modified, custom ...etc android 2.2 to work on XT720. Install/Upgrade/Modify firmware won't unlock the phone.
4. I tried the follow unlock code sellers on the internet, some honestly refunded my money, and some gave me BS unlock codes, these are the ones u should not try:
MobileInCanada(honestly refund)
WickedUnlock (gave me non-working code)
becareful these guys have multiple mirrored websites,so if u see similar only color changed website, it belongs to the same group.
I have yet to unlock my XT720... gonna wait 3 months

Have you tried flashing stock ROM, I think it's the only way you may use your mobile in your country, it's nothing to do with android version! and also does matter to superuser mode as well.
you need the following:
1. stock ROM for your country (google XT720 stock ROM)
2. RSD Lite (newest version is 4.9 I thing, google)
flash it and all done!
i purchased mine unlocked from Singapore, and then loaded the UK ROM
then I got root using this method

I am new to this Root & Flash except reading in Blogs.
If i fallow this steps 1 & 2 is my mobile will my mobile get Unlock, so that i can use any network.
If possible can you explain me clearly step by step how to install all this applications in my Mobile.
Thanks to All In Advance
the rooting is not to unlock the phone
it only unlocks the admin account, so that you can do system level stuff, with programs like AdFree and Titanium Backup
for SIM unlock you need a special number that the carrier could provide you
or if you go to those unlock sites (which usually are fakes)

You are giving not enough information for us to help. Which step did you stuck?
Did you download RSD lite v4.9 or higher?
Did you download correct stock ROM for your region?
Or at least what region are you in (or what carrier are you going to use)???
What do you mean by lock or unlock???
Did you see any wording "lock" on your mobile? Or it just not showing your carrier?? Or you can post a photo showing your phone detail in >setting>about your phone!
Did you do any setting to try to manually seach your carrier or have your tried factory reset??
Too many questions!!!
It's not just a word that we can help you out!
I am in India, when i insert India Service provider Sim Card in my mobile , its saying phone is locked, as per my understanding i need unlock the phone with unlock code to make a incoming and out going call. I brought this mobile from Canada 3 months back from " Wind Mobile "
When i contact Wind Mobile they are saying i need to be active with their service for 90 days then they will provide unlock code .Being in India i cannot activate their Sim card even though it will be more expensive for me due to rooming charges.
Even i tried to get unlock code through some web sites but they are not working.
My question is that if i install 2.2 or 2.3 version in my mobile, is that going to unlock my mobile ?
Is their any other process to unlock my mobile like Flashing/ rooting or any other solutions.
Please try to help me

No, at least not at the moment
changing the OS, doesn't unlock your phone
there is currently no software unlock for the XT720 as far as i can tell
seeking help........
I called today to Wind Mobiles that i am ready to pay amount for Unlock Code, still they are saying that i need to be 3 months active with their services.
Can any one help me to to solve this issue
Thanks In Advance
I am in the same situation with an XT720 from Cincinnati Bell. Except CinBell policy is not to supply unlock codes for any reason. Is there likely to ever be a way to unlock the XT720? Thanks!

[Q] question about firmware,root and unlock device

hi
JUst want to understand, when you root a phone ,do i need the carrier firmware (i think you call it roms)
Cause my phone was under telus and i just did the unlock by a web site and they me send a code...
My phone is under vigin now (unlock)
What do i need to root it , the stock firmware ,or the one from bell(since it the same as virgin)
I saw that link for the carrier firmware http://forum.xda-developers.com/showthread.php?t=1739426
after i root it, can i flash it to jelly bean
Thanks
nobody?
Your question is very confusing because of the English you use and mixed up terminologies, plus you don't even say what kind of phone it is. To root it, you'll need ADB or Odin. When you root, you will load new software on the phone, typically a ROM.
A Telus ROM is basically the same as ATT, GSM. You should start there and search for the right APN for your carrier.
Get CM10 for ATT. Then look up the virgin APN info. There are app store apps to fix/set APN info.
YouTube has video to show you how. Google for your answers.
Sent from my SAMSUNG-SGH-I747 using xda premium
sorry im french
but if im unlock why do i have to use a rom from virgin
Unlock and root are 2 different things. Unlock (or SIM unlock) means you can use your phone with any carrier. Root means you have access to all files on your phone (this is like being "administrator" in a Windows computer, as opposed to being a "limited user" or "standard user"). To use the iPhone analogy, rooting your
Android phone is like jailbreaking your iPhone.
So, what do you really want to do with your device? I'm guessing you want to put JellyBean on it. If that's true, you must:
Root your device
Install a custom recovery
Download a custom ROM which was designed to run on your device
Use the custom recovery to install the ROM onto your phone
thanks
But if i dont want that triangle ,i gonna use that method http://forum.xda-developers.com/showthread.php?t=1739426
And my phone was under telus and i have unlock it to use it under virgin.
I gess i have the rom from telus!!??
So i root it with the rom from telus or bell(virgin)????
And after that i can put jelly bean without tripping the counter.
Thanks
OP, not sure what you are trying to accomplish by your title in your post, but seem you have the answer/method you are looking for..
Thank You & Thread Closed

Root Droid Mini 4.4

Hi Everyone,
I have a Droid Mini running on Android 4.4. Running on Straight Talk service.
Is it possible to root my device? I am not sure how to determine if my bootloader is unlocked.
I mainly would like to root my device to use TitaniumBackUp to back up and restore my device. I am not sure of another app that will allow me to backup and restore my apps, app data and settings, without my device being rooted.
Any and all help is appreciated.
HAPPY HOLIDAYS EVERYONE!!!

Other than the fact this is not the right section to be posting a question, I'll try and answer it anyways.
No BL unlock, not unless you can get the bootloader unlocked via a tool, verizons website, or the china guys service for ~25$USD which can all be found by a simple google.
You can try the Sunshine Bootloader unlock apk, however at 4.4.4 I am unable to use it (Droid Ultra)
The 4.4 Bounty thread is HERE which appears to have minimal attention at the moment
And HERE is the latest news on the China mans service, which appears to have gone and passed by now.
To root directly, you can give all the tools a try, and all the downloadable apks and give them a run, one by one, until you get to the realization you are stuck with what you have - unless you can downgrade and then root/bl unlock. Which by my knowledge, you can't - but I may be mistaken. Only reason I say you cant though, is if you could so could others, and there would already be more posts about it.
The last and final suggestion, buy a new mobo/chipset that had your OS of your preferred version installed prior so you can have immediate access. This is a tricky one however, due to this requiring you to tear apart your phone which isn't something most people feel comfortable doing. You also are at the mercy of whoever or wherever you buy the mobo/chipset from - as it could have water damage, or other faults negating the idea of having root to begin with (if your phone crashes every 10 minutes or so due to a short).

TL;DR
You're screwed, for the time being.

[Completed] Unroot HTC One M8?

Hi guys, I've googled high and low and I can't seem to find anything that I a)understand or b) feel is relevant to my situation.
I bought a HTC on ebay, it arrived, I put my sim in and realised it was rooted. The phone doesn’t work on my network, I knew this when I bought it so I bought an unlock code but due to the root, I can’t seem to enter it, it just says no sim inserted.
Ideally I’d like to remove the root, I’m not a technophobe and learn pretty quickly, but I just don’t understand all these different versions of firmware etc.
I followed the unlockr guide and found out my CID is VODAP001 but the main-version is blank so I don’t know which roms or what have you to download.
I’d be happy leaving the rooting as it is if I could enter my unlock code, but I can’t figure out how to do this either. Is anyone able to help me? I don’t know what’s been done to the phone, the seller is ignoring my messages, I can’t return the phone as I (stupidly) missed the description where it stated the phone is rooted.
If it helps, it says im using cyanogenmod version 13.0.201xxxx and I've seen TWRP when booting to recovery mode etc. I've downloaded a few files, used an all in one mod or something from hasoon but as yet, the file system is unchanged.
I've seen something called sunshine which apparently unlocks to any network but as I've just forked out £100+ for the phone, I don't have the £25 the guides say it charges to unlock
Thank you in advance.
