wiil it loose carrier unlock?

hi folks!

Does anyone know if i update will i loose carrier unlock.

I recently bought s4active from AT&t but factory unlocked...

Im in stock rom MF3

Thank you
[Galaxy S 4 Active General] tet1:
I unlocked my s4 active from online for $30 and then I flashed via Odin ML2 I don't have problem my phone still unlocked but only I have problem with WiFi
[Galaxy S 4 Active General] tet1:
the MF3 is better then ML2 stay on MF3 don't flash your phone
[Galaxy S 4 Active General] odiseuz:
mf3 software

Thanks for the suggestion.

I see people looking for a MF· odin file... if some one gives me the step by step guide i can try to pull it form my phone.

I rooted with active root but then un rooted to tyr the update, i jus downloaded the .cfg file and later today or tomorrow will try to adb sideload it to mine to try to get the 4.3 update.

let me know

regards
[Galaxy S 4 Active General] Miami_Son:
Don't be so sure. AT$T is making it very hard to root new phones and development for the i537 has slowed to a crawl since we have yet to get an unlocked bootloader. I fear that root users will be stuck on 4.2.2 until they are willing to forego root.
[Galaxy S 4 Active General] Devo7v:
I wouldn't install the update if I were you, you will be permanently stuck on ML2 with no way to root and no way to downgrade to another firmware.
[Galaxy S 4 Active General] crpntr:
I had best buy reflash my phone then push the update and the unlock (region away on playstore for 1.99) stayed unlocked. Checked with a T-Mobile sim.
[Galaxy S 4 Active General] lanwarrior:
I am on MF3, rooted. Using Titanium Backup, I uninstalled a bunch of built-in apps, namely AT&T Software Update and FW Update.

Now I am trying to restore these 2 apps, and Titanium Backup just hangs. I did a factory reset, and ANY built-in app that I uninstall, like the above 2, still uninstalled. I retain my root, though, even after factory reset.

I just want to restore to factor MF3 with these built-in apps. What do i need to do?

Right now even clicking "Software Update" does nothing because the app was uninstalled.
[Galaxy S 4 Active General] Devo7v:
You need to copy over the files manually from the post I linked to in the other thread you posted.
[Galaxy S 4 Active General] lanwarrior:
I couldn't find the right files for "AT&T Software Update" though. I am going through this one-by-one, but there are 415 files. :(

Also, some files were successfully restored from TB, like Samsung Link, but now everytime I rebooted, it said "Unfortunately, Samsung Link has stopped".

---------- Post added at 06:50 PM ---------- Previous post was at 06:28 PM ----------

OK, after numerous reset and whatnot, I was able to restore ALL of the built-in app EXCEPT:

1). AT&T Software update V4_2_1303_2_1

2). BlurbCheckout 1.0

These 2 files are not in the Dropbox folder provided by winter.k. Unfortunately, no. 1 is NEEDED to provide the OTA software update.

This is the first time I had this issue, so either Samsung / AT&T is getting smart on preventing this or TB messed up the backup.

Either way, I'll have to go to MF1, which sucks. Why are Android manufacturer making this just like iOS - hard to jailbreak and REALLY HARD to un-jailbreak...

FINAL UPDATE:

Well, I tried everything and nothing works. Point is:

Once ROOTED and MF3, there is NO GOING BACK to unroot or factory reset. You'll:

- Have unlocked icon during boot-up - guaranteed no warranty from Samsung if you send it back to them

- Most Samsung apps (S-Health, S-Link) crashed all the time, even after factory reset.

- MF1 Oneclick doesn't work either. I got it from RootzWiki, started it and plugged my phone and.. it just stay at:

<ID:0/009> File analysis..

<ID:0/009> SetupConnection..

Nothing happened.

Never knew that Android maker will go a long way preventing root / unroot like Apple. I now have a $600 phone that is in this state. F*ck Samsung and AT&T!
[Galaxy S 4 Active General] Devo7v:
What are you trying to accomplish exactly? It's you phone messed up and you need to restore files to make it work, our are you just trying to update your phone?
[Galaxy S 4 Active General] lanwarrior:
Trying to unroot and go back to factory state. Doesn't matter if this is MF1 or MF3, as long as the phone can receive OTA.

I tried MF1 Oneclick from RootzWiki but got these:

<ID:0/009> Removed!!

<ID:0/009> Added!!

<OSM> Enter CS for MD5..

<OSM> Check MD5.. Do not unplug the cable..

<OSM> Please wait..

<OSM> All threads completed. (succeed 0 / failed 1)
[Galaxy S 4 Active General] Devo7v:
First off, if you flash MF1 you will never receive OTA updates. You have 2 options to keep your phone official and receive OTAs: 1) put all the stock apps in your system/apps folder, our 2) flash the ML2 Odin package.

If you do end up flashing the ML2 files you will lose root and there is no way to get it back. Read more about all the different firmware in this thread ( http://xdaforums.com/showthread.php?t=2629093) before you continue.
[Galaxy S 4 Active General] tet1:
if ML2 OTA file flash use ADB is better then Odin for s4 active you will not loss any data
[Galaxy S 4 Active General] lanwarrior:
Yup, I found out about ML2 right before your post. I just did Odin on ML2, thank you help.

I did try to put all the files back, but something about uninstalling the "AT&T Software Update" app through TB is causing issue, I believe, in other folder.

Imei Null/Null

Hello sir thanks for this awesome thread but let me tell you my story i have a Galaxy s4 Active SGH-I537 and i couldnt get the update via ota so i try all the things to update it however i couldnt well then i found your solution so i did it my phone was no rooted or anything just imei unlock that was all i had on this phone. well i decide to give a shot with the zip file so i did it, and the phone start to update and it was awesome! finally was going to get the 4.3 since i dont mess up too much with my phones i was ok with the update then when the phone came back on i get my worst nightmare it gives me circle with a line across the circle instead of my bars and when i try to check out the imei its says null/null bandbase unknow and i cant longer use my phone and the worst thing is im outside the us and Samsung wont cover me here. so im kinda screwed so please help me i read in another threads that might be the efs corrupted but nothing help i downloaded the 4.3 complete package from the other post and i flash it with odin 3.09 and still no luck im still getting the same thing. SO PLEASE IF ANYBODY CAN HELP ME I WILL APRECIATE IT!
[Galaxy S 4 Active General] :
Can you get the phone into download mode? If you can get into download mode you will be ok. If you can you need to do the mf1 one click or ML2 with odin. ML2 is what you will probably be after.
[Galaxy S 4 Active General] alphabeast:
Tried dat with the MI2 still no luck
[Galaxy S 4 Active General] xAjCx:
Great to hear that your phone updated but kinda sucks to hear that you are having problems. The only thing I can think of is that there might be a problem with the radio/network service that runs on the phone. Like how you need a carrier compatibility pack when using the Hyperdrive ROM. But in this case I'm not sure exactly what it is that went wrong since you tried to reflash. :o I'll let you know if I come across something. :(
[Galaxy S 4 Active General] Devo7v:
Has anybody tried flashing the MG2 bootloader found here? I'm thinking it's just going to fail to flash, but I can't risk bricking my phone as it's the only one I've got.

EDIT: The more that I think about it, this is the bootloader for the Mexican version of the phone and I believe it has a locked bootloader as well, so it seems that there would be nothing to gain, but I still would like to know if anybody has tried it.
[Galaxy S 4 Active General] monkeyhouse:
Ok, I don't know a whole lot about modems and different FW's, but I am running safestrap and my i537 still has MF3 and 4.2.2. So, if there is a way I can pull the modem from my phone and upload it, I certainly will.
[Galaxy S 4 Active General] Mrhunter13:
y ppl paid to get the phone unlock all u need is region lock to unlock it u done it will my s4 and my s4 active ..have anybody tried safe root for 4.3 ...
[Galaxy S 4 Active General] :
Yes it has been tried a few times. Nothing works at the moment.
[Galaxy S 4 Active General] monkeyhouse:
Have you read any of the 4.3 threads? Root was accomplished previously by a vulnerability that has since been patched. Please give us more info on this unlock you speak of. I have no idea of the differences. There is more than one kind of unlock? Your message is a little hard to decipher.
[Galaxy S 4 Active General] Miami_Son:
I think he is referring to carrier unlock, which has nothing to do with root.
[Galaxy S 4 Active General] monkeyhouse:
yeah, I just wasn't sure what he was trying to say. My phone is unlocked so I could use it on T-Mobile. It's also rooted, so I gotcha
[Galaxy S 4 Active General] Mrhunter13:
yea if u do use region lock it would be unlocked to tmobile
[Galaxy S 4 Active General] odiseuz:
mf3 software

Thaks... neither way worked for me after all...
[Galaxy S 4 Active General] Kyuta Syuko:
I had this same issue when I updated to ML2. I'm pretty sure it's efs corruption somehow, but the package doesn't look like it flashes a fresh efs. I suppose it could somehow corrupt the modem as well, but I would think a reflash would fix that which I had done with two different packages (one of the odin packages and this one in this thread via the rename to zip and flash via recovery method) and still had the issue. I ended up going to an AT&T Service Center and getting my phone replaced =|

*edit*

I wonder if the efs folder on the Active works like the efs folder on the Captivate. On the captivate you could replace your bad/corrupted efs folder with a good efs folder and you'd be good to go with the correct IMEI and everything.
[Galaxy S 4 Active General] xAjCx:
Did AT&T say anything in regards to what happened or could have caused it??
[Galaxy S 4 Active General] Kyuta Syuko:
No it's just pure speculation on my part as to what happened. The guy at AT&T just tried to reflash my phone and when that failed gave me a new one.
[Galaxy S 4 Active General] Ziida:
I'm brand new to the SGS4 active. Just got mine off eBay with the 4.3 ML2. All I need to do is sim unlock and region-unlock, but AFAIK I need root for that.

I just want to confirm... from what I gather in this thread there is no way to downgrade from ML2 to be able to attain root?
[Galaxy S 4 Active General] Miami_Son:
Carrier unlock does not require root. There is currently no way to downgrade from factory 4.3/ML2.
[Galaxy S 4 Active General] Ziida:
Do any of the free Carrier Unlock methods still work when you don't have root on ML2 / 4.3?
[Galaxy S 4 Active General] xAjCx:
Best unlock carrier method thats free is to get the code directly from AT&T. Thats how I did it like 2 days after I got my phone. That method would work regardless of what version you're on. Also, root has NOTHING to do with carrier unlock. From my understanding, some unlock methods that require root access don't work after updates so still best to just hit up AT&T.
[Galaxy S 4 Active General] Mrhunter13:
region lock works ..I used it on my gf phone she wanted the active
[Galaxy S 4 Active General] Miami_Son:
Sounds like he is not an AT$T customer (bought off eBay) so unlikely they will unlock the phone for him. I have no idea about the other unlock methods and their efficacy with or without root, but as has been said, root is not required nor has anything to do with carrier unlock.
[Galaxy S 4 Active General] xAjCx:
You can get the phone unlocked still after buying through a secondary source like eBay. You need to go to AT&T and make sure that it is indeed the AT&T model and tell a rep to call into customer service for you and tell customer service you are going overseas or something and need the phone unlocked or some bs along those lines. It worked for my friend HTC One and S4 who got his phones off Craigslist. Then again it also could come down to how nice the rep is that you end up getting.
[Galaxy S 4 Active General] Ziida:
RegionLock requires root, which currently requires me to not be on 4.3 ML2, right? Thanks for trying, though :o

Well thanks for the hope. I'll give them a call tomorrow, but a friend of mine warned me that ATT's unlock system has changed. I don't think reps can help you with it anymore and now you have to fill in your request online including your ATT account number and such. I'll see if I get lucky, though.
[Galaxy S 4 Active General] Miami_Son:
Not sure what you mean by region unlock, but carrier unlock does NOT require root, as has been said several times in this thread.
[Galaxy S 4 Active General] Ziida:
RegionLock in this case is reference to this app, which alters the phone to connect to AWS carriers (such as T-Mobile).

I actually haven't yet found a carrier unlock that works without root (and without access to the code) on this 4.3 ML2.
[Galaxy S 4 Active General] xAjCx:
Best of luck! Like I said, it depends of your luck on the draw so if the rep in't cooperative the first time just try a different one. You might get better results. :highfive:

Based on that app that you keep referring to, it doesn't change your phone to connect to AWS bands. The app is intended to go from Tmo to another carrier such as AT&T however, the phone was originally released to AT&T so you won't need to region unlock it to go from Tmo to AT&T (Unnecessary step). The device (i537) itself works out of the box on AT&T 4G LTE network completely fine without mods to the modem but if you want to use the phone on AWS (Band 4 or 1700/2100MHz), you would follow this guide http://xdaforums.com/showthread.php?t=2441211 in order to get HSPA+/LTE on Tmo. Even though the guide is for use on the unrooted stock version of the phone, it has only been tested AFAIK on 4.2 and not 4.3. In any case, that method allows you to use AWS but the app you suggested is not required. As far as SIM Unlocking the device with that app, I have no idea cause reading what Chainfire said, it seems that it doesn't unlock it but just removes the region lock on Tmo Note3
[Galaxy S 4 Active General] Ziida:
There has been reports in chainfire's thread of his app having the happy side effect of SIM unlocking, as well. Thanks for linking me to that guide on AWS unlocking. That was the process I used on my i337, and I had searched and failed to find anyone successfully using that process on the Active. Thanks so much for the link!

Now I just need to sort out my SIM unlock. AT&T doesn't seem to want to help me unlock my phone. bummer.

:good:

edit:

And SORRY for derailing this thread so far off track!
[Galaxy S 4 Active General] xAjCx:
np, I've used the AWS method so I know it works (as shown in my signature). I just wanted to get info out before someone gets the wrong idea and screws over the phone. Back on main topic from here out please or start new thread/PM.
[Galaxy S 4 Active General] Devo7v:
You need to have root access and then you can copy the files over to the /system folder and set the appropriate permissions. Is there a particular reason you're trying to put them on your phone? Did you delete an app and you're trying to get it back?
[Galaxy S 4 Active General] jblank72:
Yes. I deleted all the att bloatware from my phone months ago and would like to do the 4.4 update but it fails at 25 %. I would also like my phone to be stock because I am on ATT next program and can upgrade to new phone in August.
[Galaxy S 4 Active General] Devo7v:
Since you rooted and modified the system, there is no way to take any OTA's let alone the 4.3 OTA. The only thing you can do at this point is to Odin flash the 4.3 files and then you can either flash the 4.4.2 file or allow the OTA to upgrade you from 4.3 to 4.4.2.

Just remember to backup stuff you don't want to lose because Odin will wipe your phone completely.
[Galaxy S 4 Active General] grifter56:
Im in pretty much the same boat as jblank72, i have the files there never deleted them just renamed them update fails at 26%. Funny thing is that when i saw that the update for 4.4 was out i went to check on the files and the renaming i did to them was reverted back to the standard format but i was not getting any warnings on the phone about being rooted. Please let me know if im on the right path here Devo7v from what you are saying i should be able to download the I537UCUBML2 (4.3) file from here http://xdaforums.com/showthread.php?t=2629093 i am assuming it the 1.2 gb what is the other file 685mb OTA file. And use Odin to flash that to the phone and should then be able to do the update to 4.4
[Galaxy S 4 Active General] Devo7v:
Correct
[Galaxy S 4 Active General] grifter56:
please forgive my ignorance here but what are the 2 file for. do i need them both I537UCUBML2.7z and 2400258.cfg. And when extracted there are multiple .mds in the I537UCUBML2 directory which one do i choose.
[Galaxy S 4 Active General] Devo7v:
You need to read the appropriate threads on how to update to ML2 or NE3. Start with this one: http://xdaforums.com/showthread.php?t=2625033
[Galaxy S 4 Active General] grifter56:
thanks mate that was helpful seeing the actual order of where the files go. I was able to flash it according to the post, now running 4.3 had me worried for a bit cause it hung on the att logo a bit longer than usual. going to try for the ota update now. going through all this trouble just to be able to cast straight from phone to chromecast. thanks alot again for the help.

[Galaxy S 4 Active General] xAjCx:
Thanks AjC - Just to be clear, do I need these files for "Continue Update" to recognize the update file? I'm confused, I made no modifications other than root in order to access data/fota.[/QUOTE]

I know you need to have the wssyncmldm.apk file for the update to work so I am sure you need the odex to go with it. As far as KnoxAgent, I am not sure if you NEED it or not but I just know I had it removed when I rooted my phone way back when and I just put both wssyncmldm and Knox back to /system/app and the update worked.

Have you tried copying the odex file?

I have both of these files (.apk and .odex), and did not previously remove them. Is there a reason I should replace them with your backup?
[Galaxy S 4 Active General] xAjCx:
I would replace with my backup because my odex might have the codes to make the "Continue Update" part for everything to be read. But that is just my two cents. Its from my understanding that the odex contains the data for the apk to run. Since my phone already downloaded the OTA, the next step is to install update which I opted not to which should show in the odex that I need to continue the update. (Remember to reboot whenever you change odex/apk in system for it to validate)
[Galaxy S 4 Active General] winter.k:
Thanks - I'll give it a try and report back.

No dice. Not working. Wtf.

My phone wouldn't even check for updates until I had renamed both files above back to their original names. It's downloading the update now. Thanks for the tip. I had forgotten that I had even changed them. I think that the only file in my system folder that us not the original now is TetherProvisioning.apk. I will try that one if the update fails to install and report back. I'm sure there are others that cannot remember exactly what they have done to their phone.
[Galaxy S 4 Active General] crispy1805:
Failing at 25% here too.
[Galaxy S 4 Active General] dibeachdude:
My update downloaded then failed at 29%. I tried renaming my TetherProvisioning files back to the original names, rebooted, and tried again. Now, it tells me that my phone us up to date (it's still on 4.2), and it says that I can. It check again fire another 20 hours. I'm clueless.
[Galaxy S 4 Active General] wbounds:
Tried to update 3 times. 2 times after a factory data reset. Each time failed. Download takes forever then a reboot into safe mode only to get to 30% then bam phone boots up only to say update was interrupted.
[Galaxy S 4 Active General] :
I tried different ways to get this update to work without any success. First I was on mi2 and tried what the op posted and couldn't get it to go. Then I took the cfg file and renamed it to update.zip, put it on my external sd card and tried to update in recovery, no go. But when I was watching it try to flash I did notice that it looked for mf3 files. It definitely checked the build.prop to see if it said mf3. Once that failed it completely wiped my data as if I had did a factory reset. Since my data was wiped I odined back to mf1, rooted and changed the build.prop to make it look like I was on mf3. Then I tried to update in recovery again. This did not work either. I'm at a loss and really do not what else to try. I'm going to go to best buy and have them update it. It would be nice if Sam mobile or someone could come across these files for us so we could just use odin to update but I doubt that will happen since we never got ahold of mf3. Anyways that's my trial and error story.
[Galaxy S 4 Active General] gatoraid84:
I know right I have tried everything you've done to no avail..already spoke with best buy they said to unroot the phone and they should be able to ge it to mf3..they also said they have seen it reject phones due to too many flashcounts.
[Galaxy S 4 Active General] winter.k:
Can anyone confirm a successful update via .cfg (NOT OTA)?

It sounds like we have a lot of failed attempts with different variations of software and root status. For everyone who has not got the OTA pushed to them, has anyone been able to successfully update via the .cfg file, NOT OTA ?
[Galaxy S 4 Active General] :
I'm pretty sure that when you odin back to stock mf1 it will reset the flashcount but I could be mistaken. If not I will be buying triangle away. I hate to buy it for a one time use though.
