[q] need help with qpst

Im trying to connect my phone with qpst and ive installed the correct diag drivers for my version of windows. When i put my phone in diag mode and connect to qpst all i get is USB but no phone active. my phone is rooted with revolutionary and before i rooted my phone qpst used to work. I dont know if rooting changed some kind of setting but im pretty something happened. Any help would really be appreciated. ive tried so many different things but i keep getting the same result-no phone active. i uploaded some pictures to show what it says. Thanks

Try turning on USB debugging in settings of phone. Also try setting the com port to the correct one on the PC. I think there is a configurator installed with it too...if I remember correctly.

thanks for helping but ive tried connecting it with debugging on and off. both ways come up with same result. when i change the com port to any other number i get an error saying "there was an error enabling com#. the port may not be working properly or may be busy." is there any other setting that i might need to change?

well if anyone else can help me it would be really appreciated. i still have this problem. cdma workshop connects to phone but can not read it. it says phone does not answer. qpst does not detect phone but detects the com port its on. my phone is already flashed to cricket. i flashed it without having to root my phone on gingerbread. but after i rooted my phone i started having this problem. i jus wanted a custom rom but now i cant get back to the setting in qpst or cdma workshop. would unrooting my phone make it work again? any suggestions? thanks

Why the hell are u using qpst and cdma workshop if all you want is a ROM thats what recovery is for :-|

i flashed my phone to a 35 dollar plan and now i want to upgrade to a 55 dollar plan but now i need to change my settings in those programs to connect to internet and mms.

If you use a gb rom all u have to do is change the apns in the rom to get them working no need for qpst just a sense rom with epst and the msl to edit the data settings

Thank You very much. Your 4th Picture worked. I'm using a stock Rooted ROM and I found the port that CDMAWS was using and typed it in just like you had it and hit enter and it worked!!! Thank you! I may not have helped you, but you helped me! Gimme a donate link! (If this works that is):highfive:

need help flashing to cricket using linux

So I had my usb charging port detach from the board on my phone. I got a new one, (well used but new to me) and it was flashed to VERIZON but unrooted, bootloader locked, and s-on. On my computer at home i couldn't get the phone to communicate with the computer using windows 7 64 bit. I had flashed and rooted the old phone so I'm not exsactly new to this. For some weird reason I could not get the NEW phone to communicate with the computer with the same drivers from my old phone. I went to a different computer and the drivers loaded fine. however upon flashing the configuration file from my old phone, (a configuration file obtained off this forum, the qpst cricket configuration file) to the new phone using QPST the phone did not recive ANY service (cricket or verizon). I have no bars at all. upon reading the phone through QPST all the settings took to the phone but theres no service or 3g. After several attempts to load the configuration file to the phone at one point i had 2 bars light up briefly indicating that there was service then disappear and cant get service.
Would using linux to flash the phone help? I couldn't find anything on google or the search bar on here on how to use linux to flash the phone to cricket.
Only possible thing I can think of on why I cant get any service to this phone is i have yet to deactivate the old phone. is it possible cricket is blocking any service to this phone because the MIN is already registered to my old phone?
I know this post is kind of confusing so please let me know if theres any way I can clairify it.

Well using qpst on linux is not very easy. Windows is your best bet. Also to get full service cricket must change your service to your new phones esn. Or you have to clone the esn which xda does not allow us to talk about on their fourm due to legal reasons.
Now if you have everything set correctly you should be able to get data to work but sms, mms, and cell service is all linked to esn. If you are getting now bars I am willing to bet your prl needs to be changed.
I have flashed several Og evos and 3d evos. Along with doing the unmentionable (cloning). Check your messages I will send you a pm with some information on flashing to cricket.

I need to rephrase my statment. The problem isn't not getting service to the phone the problem is not getting ANY SIGNAL at all. and im using the qpst settings for cricket off this forum. But i may have found out the problem. I looks like the phone may have been updated, i just saw some options on the phone my old one did not have. Sprint optimizer plus the roaming settings were set to sprint only. BTW cricket doesn't care if a phones ESN is clean or not.

which rom are you using? did you change the prl when you flashed over to cricket? did you change the msl code? you actually dont need a computer at all to flash the phone. on any of the stock rooted roms yo ucan change the needed settings right from the phone itself using the dialer codes. ##data# #, #7786#, ##000000#, etc etc.

Stock Rom.
Yes I did can't remember off the top of my head which prl.
Not sure what the msl code is, if its the same as the MIN that I called cricket for I used the same one as my old phone, should that be different with different phones? (min number)
I did not know that about flashing using only the phone. I'm not sure what is search for, to find that tutorial so if you'd be so kind to link me to one or write a quick step by step for that is be super grateful as Windows 7 (64bit) decided to not have the drivers work anymore from when I flashed my old phone. I've read everything on installing the drivers and tried many different versions of drivers including ones off here. I've tried reinstalling Windows multipul times. I tried using Linux (mint) and virtual machine (xp) but can't get Linux to communicate with the phone. And after using a friends computer and getting the drivers working with win 7 I loaded my old config file for qpst, the config file for qpst for cricket off here, and tweaking different settings, no signal and no 3g.
I've been working on this for several days and am getting tired of having a palm computer that only works on WiFi, so as said, a link for flashing using the phone only or you taking time to write one up, (it doesn't have to be pretty) would have me owing you BIG TIME.
Something else I've noticed on my, "new" used phone is that it runs significantly slower than my old one did. Hitting home key with no widgets running can cause the phone to take a good 5 seconds to load. Hitting the app drawer can take also a good 5 seconds to load all the apps.
BTW ##7786# didn't seem to do anything but I think I edited ##000000# correctly putting my MIN in both fields....unless there's supposed to be a 1 in the begining. Not sure what the data settings are supposed to be.

yeah sorry that code is supposed to be ##786#
some of the other codes you might want o use to confirm that your settings are correct are
##786# - EPST - Status Menu
##3282# - EPST - Data Programming Menu (User Name, Advanced, Restore, Enable HFA, DSA Server, MMSC URL)
##3424# - Diagnostic - Connect to phone in diag mode (im sure you already know that one)
##72786# - changes DSA back to Factory
*#*#4636#*#* - Phone Information - "Phone information, Battery information, Battery history, Useage statistics, Wifi information"
thats all i can remember at the moment.

*#*#4636#*#* if this can be edited this might be able to be fixed in this menu however upon dialing this the number cleared like it was about to do something but it didn't do anything. was this the correct code?

The code is correct.
Now here is a very handy code but it does not work with every rom. ##775# it allows you to change prls. You will need to know the msl code and if you are on a rooted rom you can use msl reader from the market. You will also need to download cricket prls and put them on your SDcard.

[Q] How to flash Tab 3 from sprint to another carrier?

Hi, i just bought a Tab 3 from sprint and i was wondering how to flash it to another carrier, i understand the first thing i have to do is to put it into DIAG MODE but as you well know it does not have a dialer so i downloaded anycut and added the PhoneUtil Shortchut on my home but set it to Modem but my pc just recognize the Samsung Mobile USB Modem and i can't do anything on this port, the one i need is Samsung Mobile USB Serial Port in order to get connection with the tab for flashing.
Does anyone here have flashed this model to another carrier?
The model of my Tab 3 is SM-T217S.
Thanks.

firstly you dont need a dailer to put the tab in download mode secondly are you talking about unlocking it to use another sim?

i'd like to unlock the sim card but is can't i'd to flash for 3G(EVDO) network using DFS or CDMA Workshop.

I don't think that's possible

diag mode phoneutil for tab 3
I was able to get tab 3 in diag mode using a cmd terminal scripted (I found on the web) once and able to connect to qpst config but had a ? Mark next to esn. So I reset the tab hopefully being able to get back to phoneutil mode and recognized on qpst. Had no luck that way again, but I figured out another way hopefully this can help someone help me. But this new way im not even getting the phone showing up in qpst but I am getting phoneutil with dm+modem option. Ok. Im no way a expert but do fiddle so I used quickShortcutmaker.apk to make a activity on home screen the activity was factory mode. This activity gives you a keyboard gui. Assuming its the phone apk we dont get with tabs. So from there you can type ##3424# for phoneutil mode. If dont work, I also put a phoneutil.apk in system/app folder too. Not sure if this what helped so try either way and let me know if you getting closer to flash.

i flashed tab 3 Guide
Ok i just flashed the TAB 3 to MetroPCS. This how I done it, First of all I been flashing using the great wealth of info from this site for years. (BUT THIS IS MY FIRST TUTORIAL SO BEAR WITH ME) Okay the problem is getting the TAB 3 recognized as SAMSUNG. MOBILE USB SERIAL PORT in device manager . So I just Downloaded QUICKSHORTCUTMAKER from PLAYSTORE then i created an activity on homescreen the shortcut is name factory mode you'll find it if you scroll down the new activities. press OK and now its on your homescreen. from there you press the factory mode icon on home screen. This get you a dialer GUI. type in ##3424# that brings up DM settings. from there I just followed the other post to provision the TAB3 to my carriers of choice.
This is where I ran into Problems. It showed up with ? mark using CDMA configuration when changing esn but works perfect in DFS tools with port connection so I did ESN change using that program. and i also slowed down my setting in device manager to half with receiver and transmission buffer flow in SAMSUNG. MOBILE USB SERIAL PORT under properties, port settings and advance tab. another thing is you might want to do is uninstall sprint activation in Titanium backup before Provisioning because it'll try to restart sprint service for about 5 minutes, til its disable. If your not getting a connection in DFS anytime during the flash the only way I cleared up that was by factory reset with cache and delvik wipe for good measure in recovery. then download quickshortcut.apk again for factory mode access.

Just picked up 1 yester day
Ok so I have made some progress on this but I can't get the MSL & the 16 Digit pw that is working won't let me write to all the are's I need to write to.
So I Installed APEX Launcher & made a shortcut on my home screen called Factory Mode(Thanks to poster above)
then I opened it & a dialer showed up I put in ##3424#(##DIAG#) & got the normal Samsung Phone Util Screen so I Clicked PDA then Qualcomm USB Setting then clicked the BOTTOM 1 which is DM+MODEM+ADB I was able to get a Serial port in CDMA WS,DFS & QPST. FYI A couple of the other setting as well but use the Bottom selection like all other Samsung Phones
I am on 4.2.2 so I am going to try to Downgrade to 4.1.2 to see if I can get the MSL/SPC cause that's what's stopping me from getting working data on Selectel or any other Verizon MVNO for that matter. I'll post back if I make more progress,
If I don't post back that means I haven't had time or haven't made progress but i'll be tring to get this flashed cause i just picked 1 up so as long as I don't get to busy with customers i'll be on it.

I called sprint for my msl code and got it. But if your on Verizon tab then its just 000000, the 16 digit password that worked for me is 2012112120131219. I also in Dfs had used both msl and 16 digit to fully unlock. Phone hopefully you just need one. Let me know

I'm on a Sprint Tab 3. I have been flashing for yrs I am a dealer & flash everyday & I used that 16 Digit PW & everything wrote but the ppp username for some reason. I didn't try to "Repair" the MEID cause there's really no need to if your just going for 3G on a Verizon mvno Like I am. I would actually like to put it on T-Mo's $30 5GB of Data plan to b honest. I'm having issue's getting back into the Phone Util screen now. I flashed the Stock Deodexed had issue so I tried the Stock Odex Rom & just now figured out that the date is wrong on the Backup I made so I'm trying it so hopefully it will work & let me back into the Phone Util so I can keep messing with it.
I forgot to mention that that 16 Digit PW is also the same as the D710 & Sprint & USCC S3's & S4's. May also be the Default pw for Samsung. Just thought I would mention that incase some1 has it marked as 1 of those in their CDMA ws Folder like I do
Ok Update #3 or #2 whatever lol So I was able to restore my backup & get back into the Phone Util & Get Diag YAY whoo that wasn't good.

reconnecting to dfs

I had to go to recovery cwm and factory reset and cache, devle wipe when trying to reconnect to Dfs. you have to change meid and ESN then provision tab under CDMA. Unless youre trying to flash under T-Mobile Sim which I haven't tried but might been better speed and 4g possible. If so and get it working I want first dibs on tutorial lol

Ok so I was able to get this flashed to a Verizon MVNO so is anyone needs it flashed or help getting into diag mode let me know.
After I make a video ill post a link to it.

To my belief you cannot "flash" a sprint carrier to another. You have to get at least a sim card from the Verizon or other company to be able to use it.

Not true at all my buddy. just not true info at all. you can flash almost any cdma device that you can set in diagnostic mode and write information. Qualcomm and VIA chipset included. I have been flashing phones for years and flash many of these tablets as well. On a side note you can very much SIM unlock these Sprint GS4 and N3 etc , just google it before telling another guy misinformation....Sprint and Verizon are only using those SIMS for 4G authentification. it does not control your talk/text/cdma data at all
For anyone wondering this tab is flashable. Disconnect usb cable and often disable and re-enable diag while disconnected. this will bring back the port. you'll often have to close cdmaws or dfs for the port to become writable again.
Use the S3/S4 flashing methods and script to 000000 your MSL IF youre planning on a cricket or Verizon mvno

In order to get in diag mode you must download quickshortcatmaker from play store and then open it and search for factory mode and make shorcat. Then open the shorcat and type ##3424#. But you must have the 6dig code to access the menu.

Every time I try to read device for flashing, software freezes. What gives?

Hi! I'm using both Basic Flasher and CDMAdevterm to try to flash my galaxy note 2 to PagePlus. I've used these tools before to successfully flash my LG G2 to PagePlus.
The problem happens when I try to read the devices.
1) Drivers are installed (and reinstalled)
2) Device is in developer mode
3) USB debugging is enabled
4) I type ##3424# on the com pad, set it to CDMA Modem, and qualcomm USB settings to either MTP + ADB or DM + MODEM + ADB.
5) I connect to the device (two com ports are listed, I've tried both)
6) I Try to read, and the software crashed, using either tool.
Any advice for me here? I'm really scratching my head on this one, even after rooting around in support threads looking for answers.

I use dfs tools to flash the note 2 and it worked great. Maybe give it a try. A quick google search will get you a link. The trail (free version) is all you need.

I've tried that, I cannot get it to connect properly. All the fields that should fill in with information about the phone say CPS NA. Any advice?
I've put the phone in Diagnostics mode using ##3424#, set it to CDMA MODEM, and qualcomm settings are on DM + MODEM + ADB.

Performing a factory reset solved the issue. I have new issues now, though. The cycle of tech and troubleshooter continues!

Getting DM + Modem + ADB working 5.1.1 ok1

I've successfully unlocked my Note 4 and I'm trying to get it to work with AT&T LTE, now I am following this guide here
http://forum.xda-developers.com/note-4/general/enabling-additional-lte-bands-att-t-t3160864
and I have looked everywhere to try to figure out how to get DM to work on Lollipop with the sm-n910p. A lot of places say to go into recovery and select DM Logging, but that option is not there when I go into the stock recovery for OK1. Does anyone know how to get here?
Thanks!

@ssjgoku24
I'm unlocked also, and use att. And i have tried similar guides here: http://forum.xda-developers.com/galaxy-s5/general/how-to-add-rf-lte-frequency-bands-to-t2886059
And
http://forum.xda-developers.com/cro...ad-progress-please-leave-im-updating-t2871269
But i couldn't get it to stick. I don't know if it'll work on our device.
Before i continue I must state this is very dangerous and can hardbrick your device. I almost did myself. You have been warned!
Anyhow, use galaxy tools or idone unlock app to access hidden menu, then select 'phone util' and 'usb settings' from there. I've attached pics.
If you attempt, and get it to work please let me know. But like I already stated, this is very risky. Good luck and hope this helps.

Thanks for the info. I did already try doing that, but my computer never recognized the DM. So i was not able to use software. I'll try some more things once i get a chance, and I'll be sure to post results if in successful or not and what i did.

Oh. I just remembered, when i tried this(it was a while ago) i used Efs Pro to switch to the right usb setting. Cause if you read all of the guide i used. It states that official roms block us from changing this. I do believe i was using Cm12 on my phone. Then used efs pro to switch phone usb to diagnosis mode (or whatever it is).

So i was on vacation and finally got around to trying some things out. First using EFS Pro i was able to get my phone to show up as a samsung communication port in device manager. I am not sure if that is correct since in QPST it didn't show up as a diag port, i had to manually add it as COM4 (5 was also there and tested). I was able to see my phone but when i did a software download, it said the system was busy and if i hit "switch to" it would open the start menu, then pop backup. Doing this 3 times would then atart the download. Once the download hit 12% it would error out stating like "could not communicate in diag mode." This leads me to believe the phone is not actually getting set to diag mode. I have also tried to read the phone with another tool in QPST, but it always fails to read.
I tried double checking the settings using *#0808# and making sure dm + modem + adb was activated which it was. I also tried RDNIS + DM + Modem which resulted in the COM port changing to 8 & 9 but gave the same results.
When you tried QPST did you recieve these errors?
Note - I used the stock rooted ok1 rom , firmware, and baseband. I tried pd1 stock rooted rom, firmware, and baseband as well.
I was also using this in a windows 10 vm and tried on a windows 7 vm, since I have a Mac running osx.

I've successfully unlocked my Note 4 and I'm trying to get it to work with AT&T LTE, now I am following this guide here
http://forum.xda-developers.com/note-4/general/enabling-additional-lte-bands-att-t-t3160864
and I have looked everywhere to try to figure out how to get DM to work on Lollipop with the sm-n910p. A lot of places say to go into recovery and select DM Logging, but that option is not there when I go into the stock recovery for OK1. Does anyone know how to get here?
Thanks!
