Text Message Sent Confirmation - How to disable?

Everytime I send a text message, it pops up a message letting you know that it was sent. It is extremely annoying. Is there anyway to turn it off? I went into the options and unchecked the boxes, but that didn't work.

Got under my skin too! Download CeRegEditor to your pc and sync your phone via WMDC run the CeRegEditor make connection within the program and go to tools and then unlock registry, then follow these keys HKEY_LOCAL_MACHINE\Software\Microsoft\Inbox\Settings\ change key value SMSNoSentMSG to a value of 1. Save the edit and perform soft reset. Tada no more annoyance!!! If you dont like the thought of thumbing through your registry then you can find .cab file that will preform it for you. And also you can download other programs that for the life of me I cant think of right now and install them to change this and other settings on your phone. Just do a search and youll find them. Hope this helps!

Thanks for the reply. That sucks that you have to do all that to get rid of this annoyance. What were they thinking when they put this message confirmation in? Wow, what a mistake.

I am pretty sure that I used HD tweak to turn it off. 2.1 - Sent notification- disabled.
Very useful app as is Schapps Advanced Config tool. Both should be on your phone.

I use "Rhodium Settings Tool" by Tom_Condom. http://forum.xda-developers.com/showthread.php?t=549135 once installed go to menu>text massaging>notifications SMS sent

Dell Venue Pro Registry Editor

Thanks to Dave Amenta, i got around to the Registry Editor in the Dell Venue Pro. I am able to read values, but not able to set them..May be i am doing something wrong. I am giving it to the community to crack it open.
Here is what you need to do to get to the registry editor:
1. Go to the EM App in the DVP.
2. Choose RD Test. It will prompt for a textbox to enter something (its basically asking for password). Enter *#6336# . Now voila, you are in MFC Test.
3. Scroll to the bottom of the list and choose About EM.
4. Now it will say sorry..bla,.bla.. It will also have a textbox for another password. Enter *#734#
5. Voila you are in Registry Editor.
6.To read a value, go to the 'Path' prompt. While in, choose L M/C R/C U, etc..they are nothing but HKEY_LOCAL_MACHINE\HKEY_CURRENT_USER,etc.. Then enter the remaining path name. In the Key field, enter the key you want to query. In the Type, press the down arrow and choose the type. Now hit the 'Get' button on top, you will see the result (If you enter all right). If you want to set data, i think you enter the value in Data field and hit set. But, so far no luck. Iam still researching.
IMPORTANT: DO not do this as this is super advanced user mode. You might end up brick'ng ur DVP if you do not know what your are doing.

This sounds awfully similar to the LG registry editor on the phone. I do not have a DVP in my possession, but I know a friend who does. I shall try this and let you know how it goes. (BTW, Dell Venue Pro works on Wind and Mobilicity in Canada)

I am trying to do a AT Hyperterminal command to unlock the phone.,Will see how it goes.

It looks like the button isn't wired up to perform the SET command - the event handler is there, the button is there, but clicking it even without entering any data should return "1", but it's not doing anything...
What do you mean by AT unlock? What commands are you going to send to the modem? Do you have the modem drivers? If not, take a look here: http://forum.xda-developers.com/showthread.php?t=929468

When i get home, i will post the Registry Set Command CS code.
AT command - Yes, the command to the modem. And yes, i used the HTC Modem driver you linked for the DVP. I am able to query the modem from the modem properties - but i can't enter any commands in that properties window. So i am going to do a hyperterminal to send AT commands for SIM Locking and try to unlock it.
I also came across a test called 'SIM Lock' in Protocol, which returns what is its locked to.

The registry set command is:
IEmToCom.sync("EM:REGISTRY_SET:" + <path> + "," + <key> + "," + <data type, e.g. DWORD> + "," + <data> + "," + <path_type expressed as int> + ";", 1, false);
I was working with Dave over the weekend, but it looks like whatever value we insert is not being accepted - quite possibly because Dell hasn't implemented the interface yet.

this should surprise me and yet...
THIS IS DELL!

For the AT unlock, go to protocol, then TMO, then AT Command - Here you can pass various AT Commands. Unfortunately, we need the Password to reset any setting here. The password is 8 char long. And the DVP is 'ph-net pin' locked.

damn.....i think it probably means that we need to get the modem rom somehow in order to figure out how to generate the unlock PIN

I'm probably missing something really obvious here, but what does SIM unlocking have to do with registry write access?

It was a off topic discussion. I should have started a new thread for it. My mistake.

Is there anyone volunteering to reset their phone (cold boot)? I think i might have found the way to edit the registry. There are 2 modes for the EM App. One is Driver and another is socket. Not sure which one is by default. But i know how to change them. It requires a reset of the phone (cold boot) to take effect. I have too much of data on my phone to try it and reload everything. I can PM them the details and see if they are able to edit the registry.

You could try calling new EMToCom() rather than EMToComByDriver() when you initialize the connection, and see if that works. I've tried it and it seems that it fails to execute the command, with the debug window printing:
A first chance exception of type 'System.Runtime.InteropServices.COMException' occurred in EM.dll
calling COM receive error(socket) : 0xffffffff
I tried calling the turn on LED command via my flashlight app that works fine with the driver connection, but I'm getting the same exception when I connect via socket. Do you know if there's a special way to send commands if you connect via socket?

Was it doing the same blank result box? Any difference did you notice with either the Driver or Socket option? - i mean not just registry editor, but overall.

blank result no changes =/

I hope we all find some progress on this because I believe that this is what is holding us back from a lot of customization on this phone....

[primoc]method to gain your nv keys for backup

k guys, this thread is coming about after respectfully moving the discussion from kalaker's s-off thread.
i've been looking for a while about how to back up my nv keys for data, just in case anything happens to my one v. this is thanks to New Optimus (for steps 8-10) and jmztaylor, who informed me the open sesame door trick works. I AM NOT RESPONSIBLE FOR HOW SOME MAY USE THIS. open sesame door trick has the potential to screw your phone up if you dont do it right, or delete an nv item.
CDMA ONLY (i dont think gsm works the same way anyway)
YOU ARE NOT MODIFYING ANYTHING. All you are doing is backing up your AAA and HA keys. they are used to identify and register your device's data on the VM network. IF YOU MODIFY ANYTHING, ITS YOUR FAULT IF YOU SCREW IT UP.
step 1:
download and install qpst. im not linking to the file, you should be able to find it easily enough by googling it.
step 2:
open up qpst configuration, and let it sit in the background for a minute. install the htc diag drivers for one v from here: http://www.htc.com/www/support/
look for the one v, and download and install the HTC Sync program which will install all the drivers you need.
step 3:
close out of htc sync once its installed, its an annoying program anyway. connect your phone, make sure adb debugging is enabled in developer options in settings. open the dialer, type in ##3424# (##diag#) and a screen will come up that says on and off, with select at the bottom. click on, then select, and it will ask you for your msl code.
note: your msl code can be obtained by a app in market called MSL Reader, you need root for this. follow the prompts in the app, its easy enough to do.
step 4:
after entering your msl code and entering diag mode, go back into qpst configuration. click on "add new port" toward the bottom right, and make sure when the window opens "COMx- USB/QC Diagnostic" is selected and click ok. qpst configuration should now recognize your phone as SURF-MSM7830. if it doesnt, update your version of qpst.
step 5:
in qpst configuration, click on "Start Clients- EFS Explorer". make sure you put your msl in the box that says spc, and click ok. a please wait window will pop up, it will only take a few seconds.
from New Optimus's post: http://forum.xda-developers.com/showpost.php?p=29951978&postcount=796
8. Once the phone reads completely make a new directory named (open sesame door) without the parentheses and all lower case
9. After making the new folder locate abd.exe from the android sdk install folder and press: start, run and type cmd then press enter you will get a command prompt window that opens up navigate to the android sdk directory and type; adb reboot, the phone should then reboot if you’ve done as you were supposed to.
10. After the phone reboots read it again with QPST EFS Explorer which still should be opened, you will notice that the red no access circle has been removed from the nvm directory so expand it and go to the num directory,

(note: edited New Optimus's post to remove links to esn/meid changing which is frowned upon in the forums, also i already had the open sesame door folder created upon making the pictures.)
left click and drag 465, 466, 1192 and 1194 to your desktop.
keep 465,466, 1192 and 1194 in a safe spot, they are how you have data on your phone. if something happens to your HOV and those are gone, good luck getting data back.

Quick noob question, do these files get generated by the carrier when you activate the phone?

Do AKEY, SSDA and SSDB files need to be saved? if so, where are the files?

whoshotjr2006
I know the content of file 0 and 1943. Could you briefly describe the contents of these 4 files (465, 466, 1192 and 1194)? Which one is HA, AAA, SSDA and SSDB? Are there any more important NVM files need to be saved?

Got sooo excited when I saw this. Used to switch firmware's on my optimus v with the firmware of the optimus s, and use optimus s roms. Had all of my nv data and everything else backed up. Forgot you have to have be on an aosp rom for this to work because you need a port. -_- I don't have a stock backup and right now I'm tethering, so it'd take awhile to download a stock backup. Guess I'll have to wait a week or so.

nvm, I found a backup. I tried it out, and i got to the qpst efs explorer. I did the open sesame door, and it unlocked the nvs, but I only had a couple of the files from the list. I did not have 465 or 466. Also, I had an issue when I tried to recognize the phone. It did recognize the phone in diag mode with the port, but not as surfmsm7830. I have the most updated version of qpst.

I'll have to check what version I'm running of qpst, I know its close to the newest if not the newest. It wouldn't recognize my phone correctly until I had a new enough copy.
Also the first time I tried the open sesame door trick, I too had the limited nv items. I used the ruu to go back to stock, and once I did that the open sesame folder dir survived the ruu and unlocked the rest of the nv items.
Hope that helps.
Sent from my One V using xda app-developers app

What version of QPST are you using for this? I get an error "Online connection failure: Unspecified error" when trying to connect.
I think my phone isn't getting read properly by QPST because under phone it says "(unknown)" even though the other fields fill in correctly.
CDMA Workshop reads my phone no problem, but this thing no luck.
EDIT: Found an updated build and it displays the specified info under phone. Not sure what the lowest working version is, but v2.7 build 323 will not read it, build 366 will though.

[HOW-TO] Flash Sprint Galaxy S3 to metropcs with 3G speeds..

Hi there every one I have been flashing phones to metro PCS for a while now But this is my first How to. I'm going to show you how to flash your sprint/Verizon Galaxy S3 to metropcs or cricket, with 3g data working.
What you'll need:
DFS demo mode will do. But if you can, make a small donation.
Samsung drivers. Just download keys from http://www.samsung.com/us/kies/

if you didn't get nothing back go the the screen that asks for your msl and type any 6 digit number when it sais wrong code go back to the terminal and re type the comand and wala. If you use the app same steps just whith the app.
Now that you have your MSL open DFS, now go to your phones dial pad and dial *#7284# and select qualcome USB Setting, now select the last option DM+MODEM+ADB and plug in your usb to your pc. I normally open device manager to see what port my phone is, I sugest you do the same.
Now that you know what port your phone is on DFS click on the port tab and select your port now find the MSL or SPC space and enter your MSL then hit the play button to the left, now that your phone is unlocked we are ready to make changes.look at my images so you can compare.
Click on the programming Tab
Now hit the read button and change the MIN number MIN D , SPC, and MND number for the one provided by metropcs.
Now look to the right is the PRL section click on the load button look for the prl the click on the write button, now on the reset button and your phone will reset, I like to do it one step at a time. Now test out the PRL by going to settings about. or just dial *611 from phone and you should get metropcs. If you didn't, make sure that the mid has changed.
Onece you have that Down re hook up your phone to DFS like before click on te program tab and now on the Data tab.

This is the biggest hurdle, which very few people have successfully gotten to work. It is not a perfect solution but it works very well for us.
Download the following Zip file (not flashable):
Follow these instructions carefully:
1. Download and install Titanium Backup. You will also need the PRO version, so you'll need to shell out a couple of bucks if you don't already own it. It's well worth it anyways.
2. Download and install APN Backup & Restore from the Market.
3. Open APN Backup & Restore, ignore the ICS warning, and click on "Backup APNs". Exit out of APN Backup & Restore.
4. Place this folder in your SD Card.
5. Copy MetroPCS_MMS_Send_APN.xml from this folder to the APN Backup folder in the root of the SD Card.
6. Open Titanium Backup, go under Backup/Restore, and find APN Backup & Restore, press and select "Make system app."
7. Open APN Backup & Restore, ignore the ICS warning, press menu, and disable ICS check. Exit APN Backup & Restore.
8. Open APN Backup & Restore again, and now there should not be an ICS warning!
9. Click on "Delete APNs."
10. Click on Restore APNs and select "MetroPCS_MMS_Send.APN.xml".
10a. Press Ok after selecting the above.
10b. Press No when you get the message asking Yes or No.
11. Using Root Explorer or a similar app, copy the SecMMS.apk file from this folder to your /system/app/ folder.
11a. Make sure you are in R/W mode and click Yes to overwrite existing file if you get the message.
11b. Make sure to delete/overwrite any existing SecMms.apk from the /system/app directory. You should only have one SecMms.apk file.
11c. Make sure to delete any SecMms.odex if you're on the stock or an odexed rom.
12. Set permissions to RW-R--R--
13. Reboot.

i tried this and dont know why my s3 keep saying Sprint and it dosent receive calls o text...
Can you please please help me if i do something wrong

Working Talk Text and Data
I literally got my talk text and data working 2 min ago. I have a Verizon Samsung Galaxy S3 that I now am using on Metro PCS.
What I did,
Step 1.
Install Samsung Drivers
Install Kies (To update: I was on 4.1.1 now I'm running 4.1.2)
Step 2.
Root Samsung Galaxy S3. I used Casual one click (It's literally one click)
- Google search key phrase 'root verizon samsung galaxy s3 casual one click'
Step 3.
Now you should have SuperSU
Download
1. APN Manager- I have APN Manager Pro
2. Titanium Backup
Step 4.
I used Titanium Backup to uninstall all the Verizon bloatware, and overall junk I don't use. With removing bloatware click on backup/restore then select and hold APN Manager Pro (or whatever) and select convert to system app.
Step 5.
If not updated to 4.1.2, do so. - You'll need to have the ability to add an APN, only possible with 4.1.2.
I bypassed setting the language etc. with the four corners technique. Google Keyword: 'android four corners trick'
Step 6.
I went out and activated a MetroPCS plan, and got a simcard. At this point I could make and receive calls and text, but no data or mms.
Step 7.
From APN Manager Pro I clicked insert new APN. this can also be done from settings -> More settings -> Mobile Networks -> Access Point Names -> More options soft key: Add new access point. (Updating from phone settings in my opinion is simpler)
Step 8.
New APN
Name: "fast.t-mobile.com" (You can put whatever you want)(without quotes)
APN : "fast.t-mobile.com" (without quotes)
MMSC: "htetep:mms.msg.eng.t-mobile.com/mms/wapenc" (without quotes.Sorry i think you understand what i mean, please put in the letters and not htetep)
MCC: 310
MNC: 260
make sure APN is enabled is checked
Everything else has 'Not set', my APN protocol also says IPv4
Step 9.
Close settings completely
Go back to settings --> Access Point Names to make sure it is still there. Select it if not selected already.
Step 10.
Power off
pull out battery and sim card
wait 10 sec
power on
Step 11.
Enjoy data and mms.

Thank you guys for the instructions, I think I'm about to do the same for my Verizon S3.
But before I do, can you guys post what kind of speed you're getting on the new Metro(GSM)/T-Mobile 3G network?
I remember MetroPCS original 3G on CDMA was horrible and I just want to make sure the Verizon S3 won't suffer the same faith.
Thanks again in advance for you input!

Has anyone tried this with either JB? My phone is on the 4.3 update and I was wondering if it will work.

Your post is very promising to me since I'm looking to do the exact same thing and not looking forward to the complicated process detailed in the OP. I have a few clarifying questions I hope you don't mind answering for me:
1) Are you limited to 2G and 3G only, or are you able to have 4G/LTE connections?
2) Sorry to oversimplify your method, but boiled down, it sounds like you accomplished exactly what I want to do more or less by simply rooting, debloating, and changing the APN settings. Is this accurate? (Yes I've read your post all the way through five times+, I get there are certain important details to follow, but is my summary correct?)
3) I get the feeling you won't be able to answer this one, but worth a shot: Do you have any idea if this will work if the Verizon S3 came with KitKat (4.4.2) installed? Exhaustive research tells me it's impossible to downgrade android versions from this version.
Thanks for sharing this, and hopefully any answers you can give me. I'll be updating my post on whether or not it works for me when I try later

You are correct, root + debloat, change APN settings. When I had the phone I was limited to 3g speeds. I was still able to use maps, and surf without pulling my hair out. Although, most everywhere I went had wifi so I just ended up using that. As far as number 3, I am not sure. I no longer have the phone. Does the APN show up in network settings now? Could you just try the settings above? You could check if casual one click supports 4.4.2. If it does, you could give it a shot. I didn't have to use it, but if anything goes wrong use ODIN to restore your phone.

My sprint Samsung s3 has no card slot, and I'm with metro, can I use this method and get my metro plan on my s3??? Please need help!!!
