[Q] Going flash happy on the SGT

Just got my Tmobile SGT last week and wanted to make it different from all my friends that had one. For the moment it was the talk of the crowd when it was running Gingerbread and unlocked to the network and running a bunch of nonsense/useless apps that made people laugh for hours. Well, somehow I ended up bored and ended up flashing it back to stock tmobile. Well, now it does not connect to the carrier and the power button just restarts the whole damn thing. And also it will not go into recovery nor download mode either. Can anyone guide me in the right direction to make it work like how it did before I owned it??? Thanks.

Strange if your tab boots into gui but you cannot go into recovery or dl mode.......

Today again I started tinkering with it and got it back running correctly. I ended up rooting it with z4root then put CWM Recovery to gain back the ability to get into recovery and dl mode. Yay! And so.... I ended up flashing it again, but this time used Overcome-Gingerbread and followed the directions CAREFULLY. Everything turned out just fine and dandy except I still cant connect to the service carrier. I think this happened when I removed the sim network lock thing. Any advice pls?

did you flash the correct modem?

Yup, I used the TMobile US one.

Okay I think I might be wording this wrong...
Noticed in the status screen it shows "T-Mobile" under Network and "In Service" under Service State. Meaning I am connecting to my carrier, correct??? And also TMobile shows up on the top right corner when on the lock screen.
But when I try to browse the Internet it returns with pop up "No network connection Unable to load page. Internet not connected."

Mmmm your APN settings are correct?

Yep! Even try a few different ones also.

In light of this, I would be pointing fingers at the apn settings, that and silly but check to make sure data is turned on in the settings.
Other than that I'm out of ideas

i believe u must flash your old stock rom CSC or replace it via root explorer .. after u did that ... fire up the dialer .. write *#272*IMEI# then choose your country code
or if you are in euro just forget all this steps and do only the *#272*IMEI# STEP and you'll get your 3g up and work

your links dont work.

I am on ATT and did not have a single issue on this rom with 3G or any other APN related issues.
I didn't even have to detect network to get it to run.

Some people need more hand-holding than others. Making it idiotproof has a niche.

i have flashed this mulitple time. fresh. unlocked. rooted. everything. i cant get it to work on my phone, i get a signal and the one bar thing but no data. its fkn gay/weird. i only get this with 2.3.4. anyone know what i am doing wrong or can help me? i woulkd really appreciate it.

Settings for internet if on 3 Network
Ok at first when i go my phone i couldn't make a calls, and when i did the phone would restart itself. So i flashed the radio to 87.00r and it worked.
Then i had to manually set up the apn in order for my internet to work (Mobile Data)
Menu, Settings, Wireless & Networks,Mobile Networks, Access Point Names, create or edit apn.
Name - 3
APN - three.co.uk
ANP TYPE - default
save settings and restart your phone - and that's it really.

I downloaded APN Manager as you stated. I'm in Minnesota, and I switched the APN to one for T-Mobile and got double the speed. Why is that?

How did u flash 2.3.4 and U have your APN set up right and select HSPA and restart. U can check if trying to connect, Go to Settings, to About phone, to Status And Its under Mobile network state!

FOR THOSE ON AT&T
If you are on the AT&T Network and you upgraded to GB from Froyo and didn't delete your APNs or carried them over using Titanium Backup, you should be fine.
For those of you who didn't or installed Navalynt's Mod/reset your data/whatever else you did to lose your APNs, you don't need to download APN Manager in order to get it back.
It seems the problem with the defaulted APN for AT&T in this particular build is that it is missing the password. If you put back in the password, it works perfectly fine. The password is 'CINGULAR1'. So for anyone having problems with their APNs, try defaulting it or just adding the password in first.
Let me know how that goes for you guys
P.S. Can we get someone to mod the default APN to include the password? Or even better, to replace the defaults and add in the defaults from Froyo build? If someone can (or i can try to look into it) that'd be amazing

[Q] Stuck 1x no data after Gingervolt/Broken Out 2

This was a new out of box phone on zv9. I rooted and wifi tethered my 4g (my only source of internet at home) but latency was high so I though I'd go back to my old decrap v1 froyo rom to see if that fixed my latency issues with this new phone (same make and model as my old one). I couldn't find any working links to the old froyo roms so begins the current problem..
I flashed gingervolt 2.0 and sim card would not activate after many attempts. I assumed this was because it's zv7 which I hadn't noticed.
So I flashed broken out 2.0 which says works with zv9. Unfortunately I didn't go back to my stock back up which I made before flashing gingervolt.
so basically, I went from stock zv9 to gingervolt and then straight to broken out 2.0.
My sim card activates on broken out 2.0 - at least I think - it's showing my phone number / prl version / network verizon in about phone, but also says mobile network state: disconnected. I have 2 bars but no 1x/3/4g symbol and no connectivity or calling ability.
I'm downloading the stock zv7 gb rom right now, but I'm guessing this won't fix it. Am I going to have to use LGNPST? And if so should I use zv8 if going to gingervolt?
I tried searching the forums, but there's 1000's of posts about 1x when the network went down and I'm on dial-up right now so I don't really have the ability to search through multiple threads.

broken out is a zv8 or zv9 rom. gingervolt is for zv7. dont flash gingervolt on zv8/zv9.
what android version does it say on your about phone menu? find out your version, wipe data in clockword recovery, then flash the correct rom.
have you tried rebooting or cycling airplane mode? that works for me sometimes.
your sim card slot or the card itself might be screwed. try shimming it to improve contacts between the pins and the chip.

Well, I went ahead and used LGNPST to flash stock unrooted ZV9 back on it and it's still doing the same thing..
It finds service, but says Mobile Network State: Disconnected in about phone.
WiFi is off, Data is turned on.. I've rebooted/airplaned and messed with the sim card a lot, but I don't think the sim is the problem since it's connecting to the verizon network just not to data.
I have 2 bars as I normally would have, just no 4g or 3g data connectivity.
kyledyr;38918762dont flash gingervolt on zv8/zv9.[/QUOTE said:
Could this be the problem even though I've gone back to zv9 using LGNPST and it still has no data? I know that gingervolt wont work on my zv9 firmware due to improper radio, but now that I'm back on a zv9 rom the radio should be working (which it is just no data) perhaps it's an activation problem or perhaps when loading a zv7 rom on zv9 firmware something has been corrupted? but that should have been fixed with the firmware flash I just did.
I'm gonna try calling verizon and see if they can reactivate my sim card; maybe that is the issue.
Click to expand...
Click to collapse

Yep, that was the problem.
Apparently, at the same exact time I flashed broken out, verizon had decided to switch my data usage allowance - which deactivated my sim card.
I called and they reverted the data usage allowance, as I hadn't activated a phone on their subsidized pricing, thus I'm not bound to a new contract.
so the good news is I went ahead and used LGNPST to flash zv7 firmware and now I am gingervolted and still have my unlimited data.
good news and happy endings.

i have a att sim, flashed it and still does the same as before flashing. says dial 611 or go to myatt.com to activate hotspot?

Not working for ST AT&T sim, wireless or tethered. 1.08 odexed.

I can't speak to JMZ's flash, but I can guarantee the manual method works (& worked for him, also). Give it a try.

Don't know. Typing this now on my A500 using First hotspot with Straight Talk/ATT SIM.

Flashed the zip and it didn't work for StraightTalk. Not familiar with the installer but seems to be a script bug when checking for ATT / ST selection.
Manually copied the ST db and it didn't work, got the error "dial 611 or go to myatt.com to activate hotspot"
And it changed my ST APN settings.
I manually updated the db with SQLlite and got it to work with StraightTalk.
The ST db file in the zip uses the old APN setings, I was provisioned with the new settings.
See this thread for details on the ST APN settings.

No, nothing in build.prop. What ROM are you running? What SIM are you trying to use? I was using AT&T via ST, is your T-Mobile via ST?
If ST, was there a recent change in the APN settings? I have read that there were some updated AT&T ST APN settings, but they do not work as well as the old ones, at least in some markets. I tried them to see if there was an improvement and actually lost all data, so reverted.

Stock 1.08.
I'm outside the US at the moment, so my carrier couldn't be further from AT&T, T-Mobile or any of their MVNO's. But the APN settings are correct: tethering works with factory unlocked phones.

You need to be rooted and s-off for changes to stick in system files. Good luck.

Ran into a tethering issue after addition of a third, but not selected APN. Tethering showed connected but there was no Internet connection. I tried setting up the new ST settings to see if my SIM could access LTE. It could not. I then simply re-selected my original APN. All seemed to work OK, except the tethered wifi device could not see the internet. The additional setting changed the order in the telephony DB list. Went back to just the two APNs and all is again fine.

I cannot get telephony.db to stick on my friend's First for some reason. No hash match after reboot every time. Tried zip installer and ADB push, in TWRP and in OS. 1.08...1 S-off and rooted. Also tried deleting telephony.db-journal first like the installer script does. So strange because I've done it with my phone. Note that I had downgraded from 1.08...4 to do this.

Is JmzJBSenseMyst_v3 new? That's what im running. I tried this on MEDUSA as well with no go.
It basically messes the phone up completely un-useable since I'm on Straight talk att blue sim and on apn - tfdata.
So how do you get tethering on this phone with apn - tfdata for att straight talk blue sim for 4g lte... ?
I can't get MMS to work at all... it won't download says download error even after putting the mms proxy and port 80 etc..

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.

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.

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.

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.
