Hi all,
I hope you can help me with the following:
Recently I bought an unlocked galaxy express i437 (the phone is originally from AT&T) and I am able to use it with other carriers with no problems but there is no way to change the technology (there is no "network mode" menu). Searching around, I found that it can be changed manually with code *#2263# and going through the sub-menus which is a pain to do.
I was thinking in rooting this phone and install CM10.2 in hopes of getting the network mode available directly from the settings screen but before I try that I need to know if the phone will remain SIM-unlock as it currently is or if there is a risk of having it bound to AT&T after the rooting process.
Thanks in advance.

The owner tells me my phone is not remembering the flash when it boots back up...He has also tried rooting my s4 and it is still doing the same thing.

Hello Xda, I am new to posting, but I am legit stuck on this and i require help so hopefully I can here. I own a US Cellular Galaxy S4 sch-r970 running stock (flashed stock) 4.3 flashed to Ntelos using CDMA workshop. Its not running 3g (damn 1x) but i hope to soon resolve that with prls updates. But before i can do this i need to find a way to root with ruining the flash (basically no flash rooting with odin or custom boot menu :'(... ). I have already tried framaroot (they don't support 4.3 with aragorn or gandalf....) and i wanna try kingo but they won't give me a straight answer of weather or not their application is compatible with flashed phones. So to put it simply i wanna root my phone and if there is no way not to ruin the flash can i keep root and reflash??? plus if anybody can help me with the prls because my phone everytime 1x is turned on/off the phone calls *228 and i know i need to update the prls.... sooooo yea if anybody can please help i would appriciate it very much. Thanks.
Hi, I am going to explain something, but I know it would not make sense to you guys.
My friend who has a Samsung Galaxy S2 SM-T989D, got that phone from a friend, and I pluged the phone to my computer. The phone was with a cellphone carrier called Telus (In Canada), and the phone got bricked because I was trying to load a JellyBean rom on it because my mom used to have that same S2 (got it from the store, not from my friend shane friend) and my moms old S2 (same model number and everything) had Jelly Bean on it. 4.4. something. Anyways. Shanes phone got bricked and I found another software to flash on his phone and I used ODIN, and not his phone looks like its with T-Mobile (a US carrier). My question is, that, Since his phone was carrier locked with Telus before I flashed a rom and bricked it, does that mean since his phone looks like its from T-Mobile locked with T-Mobile? Does flashing a rom change the carrier of the SIM???

i have never seen a rom change the sim itself.
if you manage to flash another carriers rom, as it seems you have, and it doesnt brick your device (fairly common), the phone is going to report the new carrier because its coded into the rom.
Hi guys,
Im andrew fro the philippines. So i got this samsung grand prime sm g531f from saudi arabia and it was region locked and i cant fix it on my own. And so i had it rooted and the region lock removed. That was more than a month ago. I actually dont have any idea how the repairman fix my phone. I just know that he installed an app called SuperSU.
The problem came yesterday when i turned my phone on. To my surprise the net work is locked again. It is again asking for PIN/PUK and saying that the sim is not valid. I tried to fix it, looking for tips from the internet like
- removing the sim card and putting it back
- checking if my phone is still rooted and according to root checker it still is
- using the root explorer and hex editor
- using the region lock away but it didnt work coz it is asking for a csc data
- accessing the recovery mode (i dont actually know what to do while in recovery mode)
I dont know what to do next bec. According to some internet posts region unlocking is permanent then how come my phone got locked again. I suspected thati may have done some things that led to this. These are:
- my phone memory is getting consumed and so i was forced to transfer a lot files from the phone to the sd card memory the night before.
- i charged my phone thru the usb port of my computer for about an hour or two.
Please help me remove the region lock again. The repair shop where i had it fixed is 7 hour drive from where i live. If possible i wanted to fix this by myself. Thank you guys. I hope you could help me.

Hi Andrew
Thanks for using XDA Assist. I see you've posted in this section. There doesn't seem to be much activity in the galaxy prime forum. Try pointing your question to the Android Q&A,Help and Troubleshooting. Apologies for the late reply.
Hi,
I'm currently trying to unlock the aging Samsung Galaxy 3 (i9300).
I currently don't have a phone, and so my girlfriend who has the s6 gave me her old s3.
It's on the orange network, and as said is the i9300 model, which is where the issue lies.
I'm from the UK, and instead of being locked to orange wanted to switch to the Giff Gaff network.
I first headed to their site which gave a rundown on how to unlock the S3 using the usual code you punch into the number pad, but found that I needed to be on an older operating system.
I was on Jelly bean 4.3 and needed to be on a 4.1 variant for this to work.
I downgraded to the 4.1 via the debugging menu and downloading the firmware from Samsungupdates.com and for some reason the firmware I downloaded for my region defaulted to the UK network 3's variant of 4.1.
Now that I was on 4.1, I went back to the unlock steps.
Typed in the code, followed all the steps, but then found out that the steps were for the i747 and not the i9300.
I looked online and came across an old thread on this forum from a few years ago on the subject, which talked about rooting the device and then using another app to do the job, but then others said this no longer worked after July 2013.
I'm not really sure what to do, or weather there's anything I can do.
I'm not even sure if I've messed it up by downgrading the firmware with it now for some reason booting as if the phone was on the three network and not orange.
I know it's an old and unsupported phone, but I was just wondering if anyone had any ideas of what I should do?
Thanks allot.
This is my first post... All I know about phones I've learned from this great website. I hope this is a chance to give back.
I've been playing with flashing either of these carrier firmwares on a few different Samsung phones. One being a production model the Galaxy On5. I do not know if this is an exploit or not... but this is what I did and the results of both.
SM-G550T - Galaxy On5 T-Mobile
T-Mobile Sim
I flashed SuperStarz Rom (Don't know how to link it)
His rom however is a Metro based rom..
I hit the device unlock app just for fun and to my shock it actually unlocked it. I've confirmed this with an AT&T sim card thus far. This model and account does not meet the criteria at all for the device unlock app stock to this phone.
Well I was curious..
SM-530T1 Galaxy Grand Prime
T-Mobile Sim
Tried stock unlock app... No success...
Flashed stock tmo firmware and tried again... it worked. Confirmed with a Wal-Mart family plan sim... and AT&T.
Please if anyone has the capability to try this and confirm it, let us know what happened.
Thank you!!
*I realize now this may be the wrong place to post this*
*UPDATE 4/3/17 - I performed a complete wipe and unroot on the On5... tried the unlock app for kicks... and it failed.
Because it was already unlocked!!!!*
Just did the same with the Grand Prime with the same result... seems as tho it might be legit. If someone else can confirm this I'll write a quick tut up for everyone. I also learned from my buddy that tried this after I explained what I was doing... he took the S4 Att and flashed tmo on it... and unlocked it. Flashed OG firm and remained unlocked. Or so he says... I will confirm later.
what unlocked it? the metropcs device unlock app?
Yes. And the Tmobile Unlock App on the other device.
Just tested with Galaxy Grand Express with success. Please... Anyone else confirm this??
Failing never felt so good!!! (On5)
So....
It seems to work well with later production models... Samsung Tmo Metro Att... and minutes ago with my Tmo sim, an older LG Boost phone.
Pls Anyone with any type of multi firmware capable phone, able to flash tmo or metro firms with the unlock app.. try this and let me know the results. I will be posting a full tut with screens in the AM.
I'm pretty sure I'm dying from H1N1 or Sars.... when I'm well enough to think I'll post tut.
metro galaxy grand prime unlock?
I have a MetroPCS Galaxy Grand Prime I'm trying to figure out how to unlock. I rooted it, flashed it with a paired down stock BUT I think that paired down stock got rid of the 'device unlock' app that was on my old Samsung Galaxy Core Prime because when I used that app on THAT phone it worked perfectly but I don't know how to unlock this phone or even if it IS locked (have no clue how to find out if it is). I ordered a global FreedomPop sim card to stick into this phone and give to my little girl (I want it for the tracking capabilities only for the most part, the rest I'm locking up).
This is the closest thread I can find about this subject. Any help would be deeply appreciated. I'm not a super genius for phones or programming but I can figure out how to get into the build and tinker if given the right instructions. I don't even know the mechanics of how phones are locked, though, so maybe that won't work. Again, not a super genius. Thanks, y'all.
Hi, i tried this today with a Galaxy on5 Tmobile (G550T) and didn't work. Had latest firmware installed, then installed twrp, backed up stock rom and installed Superstarz rom. MetroPCS device unlock app keeps saying 'Unlock Failed'.
Just reporting so others don't try in vain.
Yep, it's an oldie and moldie!?
