Guide - Unlock XT862 for T-mobile/ATT

Thought I would share based on my experiences on trying to get this phone to work on t-mobile. It works on ATT 3g/T-mobile Edge, but still a pretty cool phone to have.
Also another note, this is a mod that will only go through on Windows. You will need ROOT EXPLORER app for this method to work.
1 - Make sure you are on the stock XT862 ROM, if you aren't flash it via this method found here: http://rootzwiki.com/topic/4370-sbf-droid-3-fastboot-files-55959-and-56890/
2 - Make sure your phone is rooted, if not download the following and follow the steps found here: http://www.psouza4.com/droid3/
3 - Unlock the phone. This can be accomplished by purchasing the unlock code, and later entering the code upon insertion of a sim card. (T-mobile ATT sim cards will work, but you will get an error saying UNLOCK FAILED, this is NORMAL do not freak out)
4 - Download the following files and unzip it to your desktop: http://www.mediafire.com/?y1wjw775v8itsx3
5 - Click Start and open cmd.
6 - Type in the following in cmd:
'cd desktop'
'cd fastboot'
'moto-fastboot flash radio radio.img'
ONCE it flashes, then enter:
'moto-fastboot reboot'
7 - Use root explorer to push the build.prop into the system folder
8 - Reboot, select GSM/UMTS in Network Settings.
AND BAM now it works. If there is any confusion please let me know.

Nice! Is that the XT883 radio you're flashing or a real unlocked (and signed) XT862 radio?
Also - change
Code:
ro.mot.phonemode.vzwglobalphone=1
to
Code:
ro.mot.phonemode.vzwglobalphone=0
in build.prop to get normal reading on signal strength indicator.
You can also change
Code:
ro.telephony.default_network=7
to
Code:
ro.telephony.default_network=3
so phone starts automatically in GSM/UMTS mode after hard reset.

Can anyone confirm that it's running on AT&T with 3G/4G?

Thanks man I'll reupload when I get back home with the edited bits . It is the XT883 radio.

Nice Guide!
I've read some people have had trouble unlocking the D3....and apparently it could be due to it being used on the Verizon network who then alter the unlock code via some update.
Anyone know if there is any truth in this? (I'm awaiting the delivery of a used D3 so would be handy to know).

Even after the update, if you restore it to the first link and then follow the steps, you will be fine. It can still be unlocked.

Awesome! I am about to try this on my friend's droid 3. Are there issues with the market (as some have mentioned in a previous thread)?
---------- Post added at 12:10 PM ---------- Previous post was at 12:00 PM ----------
I am stuck on <waiting for device> in the command prompt after telling it to flash the radio. What sort of USB connection should I be selecting?
EDIT: I'm an idiot.... I figured it out!

Is anyone else who is using this method on AT&T experiencing super slow data speeds? I have tried the sim card in an at&t branded phone and it seems to work ok. On the Droid 3, I am getting a ping of 2500~ ms, and speeds in the 15-60kbps range.

I can't seem to add an APN and connect to the 3G network. Does anyone else have this issue? I am using a Bell SIM at the moment

Follow all the steps, no luck here
When I put the unlock code, phone shows for a sec "requesting unlock" and goes back to a subsidy lock message with a discard dialog box.
After that, I followed all other steps, and still enter unlock code appears
Any ideas?
I dont have an att sim card, Im just using foreign sim cards cause Im outside US.

You can always call the carrier and make sure they are allowing your phone to connect. I'm not sure if this is the problem, but I read about another AT&T branded 4G phone (the D3 will never get 4G) getting only edge because the carrier thought it was foreign, and they just called in and gave the IMEI number to get access.
The customer service rep may not understand your problem, but just tell them the truth that you want to use your compatible device on your valid account and they should redirect you to someone who can help.
I can verify this works on T-Mobile and AT&T since I've tested it on both. Didn't test 3g on AT&T though cuz I didn't think about it lol. I know it allows the connection to umts in the settings though.
The OP poster helped me get it working on my phone just make sure you follow the directions closely and it's pretty simple. If your unlock codes aren't working because you got them off the internet, you may need to have the phone put on Verizon temporarily to get them to give you a code. Just ask a friend with a valid account to help you out.
Good luck to everyone, this is a great hack that definitely saves some money while letting us use this cool phone. I will have to edit my build.prop as mentioned above to fix the reboot network loss problem, thanks for that as well!
Droid 3 with stock xt862 ROM working on T-Mobile via xt883 radio.img & custom build.prop

If verizon changed the codes while phones are connected to his network, changes could only be stored on a new bootloader.
There is no other unwritable part on the phone.
Wonder if the original poster used an ebay code or a verizon one...

Nice job! Pretty amazing what can be done with fastboot and signed radio images!

Custom ROM
What will happen if somebody follows this procedure and unlock the phone for AT&T but afterwards flash another rom? Will the radio still be unlocked for AT&T?

As long as that ROM you're flashing does not have radio image in it, you should be fine. If you meant sim lock - once unlocked, it will remain unlocked forever.

I was asking about radio unlock, i know sim unlock is permanent. But has anyone tried to install any rom after the radio unlock and if yes which one?
thanks

Now, I haven't tried flashing another ROM since flashing the xt883 radio.img, because I really don't mind the stock ROM with some build.prop tweaks and the help of Zeam Launcher. I would assume that any ROM you flash would cause the build.prop and radio.img to be replaced with new ones, made specifically for that ROM. You should probably consult with the developer of the ROM you want to use, and ask them if the build.prop changes specific to this process will have issues with their ROM. The xt883 radio.img shouldn't have any conflicts, but I believe it will still require the custom build.prop file which is found in the OP, or at a minimum the specific changes which allow this tweak to work.

[Q] SIM Unlock doesn't work

So I have an HTC One, it's running the latest Android Rev HD version (4.4). Recently my contract with Tmobile expired and I got a Lycamobile sim, along with an unlock code. I'm used to the network unlocking procedures, but for this HTC One, after I\ve typed in the code it says successful, rebooting, but doesn't reboot, simply freezes itself. After a while, it's responsive again, but it's showing the window for the unlock code again. I've tried putting the unlock code multiple times, each times is successful, rebooting but then again freezes and fails. What am I doing wrong? Is it the ROM ?

Probably. ARHD was based of dev edition. US carrier versions aren't out yet. So you better try with a stock 4.3 ROM
Sent from my HTCONE using Tapatalk

Ok so I had a similar issue with my AT&T HTC one. First of all make sure you don't have a security lock screen enabled (basically make sure you don't need to enter a password to get into phone). Secondly I turned my Wi-Fi off just in case (so the phone wasn't connected to the internet). And make sure you are on a sense based Rom (I was using sky Dragon Rom).

You can use the latest ARHD 41.0, when the phone is unlocked this only changes the allowed sim

I was able to use my unlock code on ARHD. I tried several times at first with similar results. The method that worked:
1) insert foreign sim
2) enter unlock code
3) wait until it freezes on "rebooting"
4) manually turn off the phone
5) remove foreign sim while phone is OFF
6) turn on phone
7) place foreign sim back, HOILA!

I'm probably late to this thread but, the exact same thing happened to me on an HTC One S running MaximusHD. I tried a number of things and found this thread by google. I finally figured out the issue. If your ROM has APM, make sure you disable it if you can. The APM option menu was causing the hangup and it worked fine after I disabled it.

Domestic Unlock of 4.3 & 4.4.1 (NAE) galaxy s4

Okay, I just got through doing this myself and it seemed that nowhere was this all said at once, or at all. So I thought I'd whip up a quick tutorial concerning how to Domestic Unlock the Samsung Galaxy S4 on any of the newer bootloaders/firmwares/modems. (Knox-enabled)
I did this on both a 4.4.1 galaxy and a 4.3 galaxy- one one NAE and one on MK2
First, for anything to work your modem must be an older one, like version MDL. Download the file SPH-L720_MDC_Modem.exe which is a one-click
Odin .exe that will flash ONLY your modem to MDL.
Steps- put into download mode by taking the battery out and putting it back in. Hold the volume down button, the home buttone and then press the power button. When it vibrates, let go. Press volume up.
Run the SPH-L720_MDC_Modem.exe odin one-click installer.
Connect the usb to computer from phone
when com[24] or whatever shows up, press start.
Now, for the domestic lock to work you first need to do the international unlock @ http://forum.xda-developers.com/showthread.php?t=2415587
It's real easy and explained well at the link above, but I'll run through it quickly anyways.
Download the s4unlocker installer from the post linked above.
Put your phone into diag mode by dialing ##3424#. Press Qualcom button and select the bottom selection.
connect (if it wasn't already) usb from phone to PC
You already installed the proper samsung drivers, right? If not, you'd better do that now.
Okay, now run the s4unlocker and press the scan and unlock button, then wait for the phone to reboot.
Now for the Domestic Unlock part.
Follow the directions at http://forum.xda-developers.com/showthread.php?t=2530610
I'll run through it real quick, too because there were a few things I wanted to mention.
dial *#0011# (or #*0011#, I can't remember)
when it comes up "No service", press the menu key on the bottom left of your phone. This brings up a menu (wow!), on which you should press "back"
Now press the menu key again and in the menu select "key input" A box will open up asking for you to type in something- enter a "1" and then press the enter key BEFORE hitting the OK button. Mine would not work unless I did this.
Now wait, sometimes it takes a good couple of seconds to give you the menu. Follow the rest of the directions from the above link, setting all the settings to what is stated. EXCEPT where he says to set all the preferences to WCDMA ALL, GSM ALL and LTE ALL. When I selected one, however, an asterisk appeared after my selection leading me to believe that you can only select one of these and so I set mine to GSM ALL and left the others alone. This worked for me, so I thought I'd mention it.
Now that you've manually rebooted after following the directions, you still have to edit your build prop to allow you to edit the apn settings. To edit your build.prop you must be rooted so root with CF auto-root http://autoroot.chainfire.eu/ download the proper one for the galaxy s4.
It's just an odin flash, so enter download mode
load up odin 3.x
hit the pda button and select the cf auto root tar
hit start.
After rooting I found that one time I had to do some of the service mode settings again and one time I did not, so I mention it here even though I think I had to because of some other error I had made at the time.
Go to play store and download build.prop editor and APN settings Shortcut
Load the build.prop editor and add these two lines to the end of the file
ril.sales_code=LOL
ro.csc.sales_code=LOL
Now reboot manually
add the apn settings widgit to the main screen and open it
click on menu and add an apn
Enter the apn settings for your carrier here. They're all different,(the carriers) but you can find them(the apn settings) easily with google, since they (carriers) all post their apn settings on their webpages.
Don't forget to save the apn settings.
Now select it.
Now reboot, since it couldn't hurt, right?
If you've done everything right you should now have an domestic and international unlocked Sprint galaxy s4. Enjoy.
I suppose you could now reflash the new modem back onto the phone, but I don't have firsthand knowledge whether this works or not- I've only read that others have said that it works. Remember, ONLY FLASH THE MODEM, the rest isn't necessary and will probably knox you all up
All I did was list these things- credit goes to all those who were linked in the above post. Thanks for all you do.

On stock 4.3 and higher you can go into settings and change your APN, so there's no reason to root and mess around with build.prop editor.

Every time i try this i cant get my wifi back up when i flash back to the nae modem. If i could get pass that then I'll definetly be do that.

I have read that the modem itself cannot be downgraded. You can run older android versions and such on the newer modems, but the modem itself cannot be rolled back. I believe it has been like that since MJA.

You can downgrade modem, but can not downgrade bootloader (aboot)

I completed both the international & domestic unlock. I believe I was successful in each. I have a T-Mo sim card inserted but am not getting a mobile data connection. I do have 2 bars of service though. So I have gotten past the red X on the bars.
I am on 4.4.2 with the MDC modem. I did not do the build.prop stuff, instead opted to just access the APN's from the default menu.
A few things in my menu were different than the OP (probably because of 4.4) such as:
I dont have any roaming menu options
I dont have WCDMA.. just CDMA and LTE/CDMA. I currently have it set to LTE/CDMA
In my APN edit info there was not a place to put in MMS protocol: WAP 2.0
Also under About Device "my phone number" is wrong.
Am I missing something to get this t-mo working?

You didn't unlock it. If you were on NAE modem while unlocking then you failed miserably because you're not able to get into the most important part of the unlock...The service menu. If you did indeed downgrade the modem then you're going to need to follow the domestic unlock guide again. If it's showing CDMA/LTE you didn't do it right. It should show WCDMA only and WCDMA only isn't an option you can just select. It gets put there by the service menu.

I said I wasn't on NAE, I am on MDC. I did get into the service menu. I did everything in the process without issues. My service menu did NOT have a WCDMA only option. It had LTE/WCDMA and that's what i chose. I just went to the t-mobile store and they verified my APN settings were correct. I am unsure of what to do at this point other than just start all over and do it again.
Anyone else?

I apologize. Long work day. Follow the guide. When it comes to where it says select LTE, GSM, and WCDMA all, ONLY select WCDMA all. At no point should you see your Sprint phone number in about phone. Also you should see IMEISV in about phone as well if you've successfully unlocked it. It'll help if you posted the steps you've gone through. Otherwise were just shooting in the dark.

Imeisv visible, definitely unlocked as i can make calls texts and use edge data on redpocket mobile (att mvno)
But in phone number I still see my sprint number and I can't get hspa (picking the wcdma all gives me red x no bars, picking gsm all gives me full bars and edge data)

From the S5 thread and now here we meet again in a revisit in time. Since I know you own and understand the L720 more than I do, could you please explain to me if this will work on a 4.4.2 NAE rom? I picked up an L720 (bad esn) for $100 and its in pretty great shape. Now I'm looking to unlock it but my experience with Samsung devices are very mild. It came on CM10.2 (4.3.1) and ive slowly caught up with things. So i understand that sadly there is no such thing as downgrading from KK to JB, I was trying to get it stock on JB with no cigar. Elsewhere I found out that you must flash something identical or above. So im planning on flashing an NAE 4.4.2 stock rom (custom recovery flashable) I found in order to attempt to unlock it cause I can't seem to find a 4.4.1 as mentioned in the OP. I flashed the MDC modem and it stuck, so with little knowledge I am assuming that it will stick once I flash this new rom? Correct me if I am going down the wrong path...
EDIT: Great nobody ever mentioned anywhere that the software used on the international unlock is for 64bit only...

The software works on 32 bit too. Actually you can even perform the international unlock WITHOUT the tool if you know how to use QPST or DFS. Anyway...
Flash full NAE. Flash MDC modem. International unlock. Domestic unlock. Win.

Must be an issue with my PC, nothing new...
And I know a thing or two about QPST. I still have it on my computer from a few days ago from when I was fixing a horribly corrupted IMEI on a G2 a friend of mine bought. I'm assuming I have to use a NAE stock tar with ODIN, because I tried a ROM of it and it lags and stays on black screens for seconds and WiFi doesn't work im sure because of the fact that the modem is older than the rom. Let's see if that works cause ive been trying to flash back to any stock ROM since I got this thing yesterday.

(Almost there...)
NEVER MIND. Got the international part working perfectly by using the Windows Vista partition on my PC. Now reading on, OP mentions that next the domestic unlock must be done, a link is provided there to another thread with domestic unlock instructions. Heres the question. The OP in the other thread mentions to hop onto 4.3 via odin. How can I get to 4.3 to domestic unlock if Odin doesnt let you downgrade?

Read the specifics. You cannot downgrade boot loaders but you CAN downgrade modems.
Unlock just requires MDC or MDL modem.

Yeah I remember that part but from what I was understanding, that's for the international. Domestic requires messing with some files and done. I already got the international part by tossing CM10.2 along with the MDC modem because stock Touch wiz would cause lag and reboots and non working wifi I'm assuming because of the mismatched combo. I DO know that obviously we need a TW rom in order to unlock domestic.
EDIT: I finally got the hint and got it to work. But I only get Edge instead of 3G. Does anyone know where I may be able to find that T-Mobile rom made for us? When I Google it I end up on the T-Mobile side.

Now reading on, OP mentions that next the domestic unlock must be done, a link is provided there to another thread with domestic unlock instructions. Heres the question. The OP in the other thread mentions to hop onto 4.3 via odin. How can I get to 4.3 to domestic unlock if Odin doesnt let you downgrade?

I downgraded from latest bootloader on 4.4.2 or was it 4.4.4? Down to 4.3 which is the absolute best ROM version for service mode menu. It got me into service mode menu on first try by selecting menu back and input of 1. What I did was first install cf autoroot to root then cwm and used cwm to flash the 4.3 stock deodexed, I only used Odin for flashing modem. Odin gave me an error when flashing modem and phone got stuck in kies mode but i got it to get unstuck by just flashing cf auto root again to make the kies mode error thingy think odin flash has went well. Turns out MDC modem flashed despite odin error.
Anyways. While on 4.3 and MDC modem I noticed no WiFi but I had sound. I followed the international and domestic unlock instructions and WiFi was still broke when I got back to 4.4.2 but I had unlock and sim card working and got bars. I am on aosp 4.4.4 now and the nae modem I finally flashed works well with this ROM but soon I gotta go to touchwhiz 4.4.4. If I go to 4.4.4 touch whiz WiFi and all else will work fine just as they do on slim aosp . 4.4.2 touchwhiz is still not giving me wifi on NAE modem. Update NAE 4.4.2 stock deodexed rooted rom i got from xda android thread did the trick and all works well now. All is perfectly working after i flashed it in cwm.
For aosp lovers. aosp requires additional things to do so aosp dialer can make and receive calls fine. I can call but there are issues until I follow another guide on xda that resolves those issues on aosp ROMs using sprint s4.

If you see system slow, no wifi, no audio and lockscreen being nearly impossible to unlock, its due to you being on a higher ROM than the modem was meant for.

[Q] Rooting N900A to Lollipop while using T-mobile.

Ugh, I am having so many issues with this at the moment. One of those things being that I am using T-mobile as my carrier. I'm stuck on 4.4 at the moment, and need to update it. But, will that relock the phone? How do I re-unlock it if that happens? I've already read that I can't flash the phone to T-mobile ROM, but are there any custom ROMs that you would recommend [I do actually use the S-pen, not sure if any have been updated to where that can still be used.] Lastly, is there any way to get mobile hotspot and tethering to work now that I am using tmobile?

I never tried this Rom.
T-Mobile Alliance Lollipop Rom on ATT Note 3
http://forum.xda-developers.com/note-3-att/general/t-mobile-alliance-rom-att-note-3-t3065127 I don't think you would have to worry about any of this as you are using T-Mobile " After the phone came up, I went to settings..general..applications...running .... and found every Tmobile app and cleared cache and disabled them. The real important one here is the Visual Voicemail. Otherwise it will keep on trying to contact Tmobile and then you will get text messages saying there is an error. Thanks @sapps
Wifi Calling is throwing a sim card error (as you would expect). Only problem is it is shown in status bar and lockscreen. I'm sure there is a way to hide it or disable it. I just haven't had a chance to figure it out."

But it's the N900A, so it's the AT&T version. Won't that brick the phone if I put the tmobile ROM on it? That's what I've read in other threads on here anyway. [Honestly I shouldn't write when I'm tired, or I would have explained this better.]. Basically, I bought an unlocked AT&T phone. A Note 3 to be exact. It's stuck on 4.4 but can upgrade to lolipop. Nothing I try will let me upgrade the normal way. I'm not sure how to upgrade it without relocking the SIM card somehow. Or is the simcard already semi-locked and that's why it's giving me the error? I also can't even find a AT&T specific rooting guide for this phone. I saw every other carrier except AT&T, does that even make a difference? And are there any ROMs that can return S-pen programs after I install them, or should I just stop at rooting if I want that? If so, I just really want to upgrade to lollipop and root the phone. I would like my mobile hotspot and wifi calling to work, but I suppose I can make do with hangouts.

It won't brick you phone. It's a T-Mobile Rom that's been ported for AT&T Note 3. After you flash the Rom, you have to Odin the N900A_OC1_ALL_Other_Stock_Partitions.tar.md5 using Odin's PDA slot. As far as rooting what you have now, just use Towel root https://towelroot.com/ (install on phone like any other app) and click "make it rain". Install Supersu, busybox and Safestrap. OR use Kingo Root http://www.kingoapp.com/ (Kingo Root will install supersu for you). The reason it won't upgrade to Lollipop is you have a T-Mobile sim card in it. It needs a AT&T sim card (I have AT&T and can't upgrade mine unless the sim card is in the phone). If you just want a rooted Lollipop Rom, but it's AT&T http://forum.xda-developers.com/showpost.php?p=59666958&postcount=2 You know since you're on T-Mobile you have to go into settings>more networks>mobile networks>access point names and change it to T-Mobile's APN. I would just root it and put the T-Mobile Alliance Lollipop Rom on ATT Note 3 on it. I gave it a try yesterday and it does have T-Mobile apps on it, just not for me. Just remember to change the APN to T-Mobile's ( just write down the one you using now).

[i537]New Easier Sim Unlock Method 4.4.2/5.0.1

Sim Unlock Method 4.4.2/5.0.1
Disclaimer: i AM not resposile for anything that happens to your phone in the unlikely event something does happen.
this has only been tested lightly but it should work all-right. this is for the i537 S4A only.
You Need to start out on either NE3 or NH3. Downgrade now if you need to. Just remember when downgrading don't flash bootloader. This needs Odin and root to succede. Now That thats out of the way you need to download some files to deal with later on.
MF1 Odin flashable
regionlockaway go to the second post and download the apk to install on your phone.
this method uses an old method in a new way.
here is the guide
1. install regionlockaway and reboot to download mode
2. Flash modem.bin with odin in download mode
3.reboot to system and use regionlockaway. follow the instructions in the app.
4. profit?
As far as my understanding after you do this you can update your modem without it reverting back to being locked. I am running oc7 modem on a T-Mobile MVNO without issues( if you want aws unlock you are going to have to use this then the appropriate modem for that and not allow for the modem to update when updating to oc7 by modifying the oc7 installer and removing the modem from it)

I am ready... I have been reading for days about sim unlocking on 4.4 and up..I finally coined up $25 for a code but takes up to 5 days, 2 days ago. my next attempts were going to be with my paid copy of CDMA WS. Either way it is just to experiment with and would love to gain the knowledge. I have a couple different carrier sims ready to go. I would love to give it a shot.....

hey guys i have created an easy sim unlock that should work for 4.4.2 and for 5.0.1
for the 5.0.1 sim unlock you have to do it on 4.4.2 and flash a modified partitions file to upgrade to 5.0.1 while keeping sim unlock.
if you guys are interested in it let me know and i will set up a few beta testers for it. i cant say for certain that it works because i dont have a non ATT sim card to test it with.but it should work. it should also allow you to enable aws for those on T-Mobile by following a secondary guide.
let me know and i will start having people beta test. i only need between 1 and 5 testers

ok ill pm you with a guide once i have it written up.
EDIT: it should be in your inbox

i was able to test a verizon lte sim and it didnt give me any issues. it regestered the number in the status. so i belive it worked. i would like some more testers to get information about it. i need more testers before i feel ok giving out the method.

Been sooo busy!!!! K, thank you for the guide. I haven't been able to try anything except a Verizon Lte sim. It registers the number and the network lock is gone. However I don't believe we will get data service with a Verizon sim as I don't believe the hardware is capable?...I wasnt able to place a call as I got" Emergency calls only", all I did was swap sims, occasionally I have to call Verizon and have them add the new phone to the plan before it will work and I didn't do that yet. Will try a different carrier sim tonight.

so before you did the guide did it give you issues with the verizon sim? and now it dosent?

It did give me issues before flashing the mf1 and after the flash and region away no nagging about sim unlock code! Havent gone any further yet. I will report back after using a different carrier sim besides verizon that is.....I think it works....

sweet thank you for the feedback man. i did the 5.0.1 upgrade method i detailed in the PM after i finished doing the unlock on my phone and it worked the same as what you described (i only had access to vzw lte sim also) so i belive i made the update file correctly also. im not really getting any bites on more testers so if it pans out well for you i will polish up my guide and post it here to have people test it instead of making them PM me.
thanks again for being my beta tester. if we get this working well we can save alot of people alot of money
ps for voice and sms verizon lte sims are useless because they still use CDMA for those features

Finally put in another sim...Put in a Tomb sim and no nagging about unlock code, I got "Sim not provisioned" as it isn't active at the moment. So I'm thinking it worked. Thank you. I was thinking I'd get voice and edge speeds with a Verizon sim in this phone, (utilizing GSM bands), in my area anyway, but maybe I'm mistaken. I'll post again after using another carrier's sim.....

I did as instructed and according to flashfire at the end of flashing, it said it was successful and it rebooted (so far) to the lollipop boot animation and am awaiting for it to get past the at&t logo screen. Its at least gotten a lot further than all my earlier attempts...I am assuming its taking a little while for its initial setup of OC6....
more later on its success or failure....
well it was a partial success....it flash and booted into OC6 but sim card is not recognized, no baseband.....now installing updated version of flashfire....should i now flash the MF1 modem again via flashfire?
well i went ahead and did just that flashed the mf1 modem via flashfire and all is up and running successfully (FINALLY!!) with root on deodexed rom OC6...
Kudos and thanks goes out to ya!

your welcome man. i figured your problem could be fixed with my method. have fun with 5.0.1

partially completed downloads
Never mind. The downloads on dev-host work from my computer but not from tablet or phone.

I stopped THE INSTALLATION of I537_OC6_Stock_Partitions_mod_sim.zip and the phone is not the most part, dead, solutions?

odin ne3
flash mf1 modem with flash fire
make sure you are rooted and have busybox
use region lock away. try with att sim in phone.

Trying to do this for my s4a but flashfire is being uncooperative, it just crashes any chance it gets. Any other flash apps this will work with?
Edit: do I need safestrap for FlashFire?
Edit2: Fixed the issue with flashfire, If anyone runs into this issue you need to flash stock NE3, and re-root.
Rest of tutorial went perfectly. Cannot test unlock status atm, but no errors.
Thanks Matteo, you're a top lad.

Will this same method work with a deodexed OC7 ROM? I only ask because of the I537_OC6_Stock_Partitions_mod_sim.zip - not sure if this still works the same for OC7. Just to clarify, do you know if region lockaway is necessary to get T-Mobile AWS/HSPA bands? I've got a working cell and LTE connection without doing any of this, so I really only needed to do what's necessary to get those bands (which I think the old modem will help enable).
Thanks for the assistance!

edit to the edit:
go back to NE3 with odin.
then flash mf1 modem
then try this
[GUIDE] AWS Unlock for i537 I537UCUBML2 (4.3)
read the posts to make it work
also check out this post if you have issues with getting qpst to work. dont follow the whole post just qpst part http://forum.xda-developers.com/showpost.php?p=56023258&postcount=68
then follow the guide i posted in my last edit to keep the aws unlocked modem while on 0C7
edit:
you can use the oc7 deodexed rom. you just have to remove the modem from the rom file useing winrar or 7zip. also you have to remove it from the updater script useing a text editor. drag it out of winrar edit it and then drag it back into winrar. that way if you flash in this order you will be fine
partitions mod file
oc7 deodexed rom.
that way you keep the modem
from when you installed and unlocked mf1 modem on 4.4.2
