I have a quick question regarding this QPST stuff. Say I load a Sense-based ROM on my phone, Stock Plus, since I already have a backup of it, and I flash my phone to Straight Talk, which I have been wanting to do lately, can I afterwards restore a backup of CM7.1 without losing the options that I changed in order to get the Incredible working on Straight Talk? In other words, can I still flash ROMs or do I need to stay on the Sense-based ROM? Thanks.
Great tool. I am however missing something. For some reason it won't let me copy the two scripts as directed. mounted r/w one time got space error so wiped phone and made this the next thing to do and still not letting copy to . . . usb_composite any ideas?
This is perfect!!
DUDE THIS WORKS PERFECTLY!!! THANK YOU!!!!
I'm A CDMA FLASHER --- I wanted to play around with some settings on an evo 4g with cracked screen and this was perfect!!!!
i got one better for ya.
Code:am start -a com.android.dmcommandservice.START -n com.android.dmportread/.DMPortActivity
what is so great about getting to Diag mode this way you say?
1. well it doesn't require root access.
2. its cross model supported. (well any model with the DMPortRead.apk installed which i have yet to see one without).
btw you can do the ##3282# in the same way... the apk is call EPST.apk. just look in the Android-Manifest.xml for the info.

Diag Mode for ICS room
echo 1 > /sys/devices/virtual/android_usb/android0/f_diag/on
echo 0 > /sys/devices/virtual/android_usb/android0/f_diag/on
echo 1 > /sys/devices/virtual/android_usb/android0/f_diag/on
echo 0 > /sys/devices/virtual/android_usb/android0/f_diag/on
I'm running CM 10.1.3 on a Cricket Samsung Galaxy S3. Every script I use, I get "no such file or directory" including after installing and setting up this zip. I've tried adb (su and not su), terminal emulater (su and not su) and I always get the same thing. I've been searching and trying everything to get into DIAG Mode, and nothing works. Can someone please help?!

Since the SGS3 has a VIA radio chip rather than a Qualcomm, anything related to QPST is irrelevant for your phone. You're probably going to have to ask in a more relevant section of the forum to get help with a VIA radio.
Hydrosity, I need some help. My dinc has CM7.2 rooted but S-ON HBOOT - 1.02.00. When I connect the dinc to my laptop, in the device manager I can see the dinc drives and the Android USB Devices - My HTC, but no com ports appear under ports.
I tried your script. It executes properly, but no diag port appears under ports in device manager.
What am I missing?

I always got error:
/system/bin/sh: can't create enable: No such file or directory
Any suggestions?

11(UPDATE: 8/24/11 New flashable update.zip for install via recovery, includes Gscript (credit goes to PinkVenture for developing the app!) and my simple on/off scripts already installed. You can link shortcuts directly to the desktop for each ON or OFF through add shortcut on homescreen, see attachments at the end of this post)
I'll start this off by mentioning that all the threads you may find saying "CM7 DIAG Enabled!" such as this one here Etc, are not valid solutions for OUR device. That may/may not work with the eris/hero(haven't tried) etc as those topics discuss. They merely SPECULATE it will for any CM7 based rom - it doesn't for ours.
WONT DO ANYTHING for you. In fact, it made my "qct_diag_enable" file disappear. Scroll to the bottom to skip my bantering and explaining of the reason this is a useful feature for people like myself, and to just show the actual findings of this thread.
So you have CM7 and (of course) are lovin' it. The only thing is you have an alternate carrier (cricket personally) and hate the fact that manually switching prl's or needing to change your EPST settings can be a pain (since CM7 has no EPST built-in!). Especially when its [*feature name here] that you would LIKE to have the ability to use, but can live without if it means having to restore (or flash one if you have no backups) a sense rom just to change any of your EPST (##778, etc) settings.
Well, if you know anything about QPST for windows (google), then you know that you need to have your phone in DIAG mode to use it (##3424) and have the hero diagnostic drivers installed on your windows machine. (For the record, I'm an Ubuntu man and my main machine is NOT dual boot, meaning I still have to switch to my windows laptop to use QPST >< but we'll just pretend you have windows and this is more convenient for *you*).
Back to the point, once you've realized all the hassle, yada yada, you just say, "Ill just fix it later, I can live without it for now." AND how sick you are of saying that, here is the solution to no longer switching ROM's for EPST, as there IS a way without the ability to ##3242 in CM7 to enable DIAG mode.
(NOTE: This is also useful for those of you already on CM7 WITH Verizon/Alltell who would like to follow the guide in the Development section Droid Incredible Wiki regarding switching to the whole Verizon PRL/Alltell Hybrid PRL, along with other guides involving EPST or ## codes found there)
Simply go to (via adb shell/terminal emulator) /sys/devices/virtual/usb_composite/diag and run (1 for on and 0 for off, respectively)
Code:echo 1 > enable echo 0 > enable
To simplify all this I've included a zip file which includes Gscript.apk for you to install, and two scripts in the Gscript directory (place entire Gscript directory on root of sdcard). Open Gscript application, then once open - menu button>add script>load file>diag on/off.sh>save for each script respectively. Then you can simply toggle on/off DIAG mode from the Gscript application (or even add shortcut>gscript>diag on/off from CM7 home screen, for each script respectively). And without further excess explanation, here's the .zip signed-diagscripts.zip flashable update.zip file for recovery
By the way, if a mod reads this, could you please move to the Development section and remove my restriction? I know I don't have my whole 10 posts etc, etc, but I don't really have enough to say or the patience to say it most of the time to post 10 posts. However, I've lurked these boards and been rooting phones and flashing phones via this forum since my first android phone back from what feels like ages ago. (going on 4 rooted and flashed to cricket android phones now, all sold except my current, Dinc)2
so wait let me get this straight. this mod is so we can update our prl??? or is this for people that would like to still run the altel hybrid prl?
because a simple *22899 will let you update it. i know this because i have been on cm7 nightly from day one and there was 1 update of the prl and it worked.1
if CM7 doesn't have DMPortRead.apk couldn't you just push it to you framework/app folder? or even install the apk and just run that when ever you need to connect to the Diag port? (for Qpst, or what ever you need it for) i'm not very familiar with CM7 so i could be wrong.
i use it to send my own serial commands. i find qpst to be more of a hassle then helpful. manuf. have been making there own NV items that are not listed in Qpst models for a while now. ie. the ERI banner for some hero's is not pulled from the usual eri.xml but instead read from the NV items. i think NV item 8042.
now, i while i was snooping around with the flash command. i notice that you can use "-s" (i think, i could be thinking of fastboot.) to specify your own memory location to flash an img file to.
now if we can find the mem location of the NV items you can simply read your entire NV items as an .img then use flash cmd to write all your NV items at once, and maybe even with the Recovery update.zip. im looking into the recovery source atm. if anyone knows where the NV items are stored plz let me know. is it mtd or mem location?
