Develop Bugs

[Q] ERM... I tried something without knowing fully what it would do.

I know that it was foolish of me to not fully research this set of commands I have copied the before and after of tit all from the command line. I was attempting to mess around with my phone with QPST. I know, I can REALLY REALLY make things hideous if I don't tread carefully with QPST, but I am willing to take the risk in order to learn, even if I do get burned because my phone bursts into flames.
Any who here is the output from my commandline which I ran because using *#0808# and switching to either RNDIS+DM+MODEM or DM+MODEM+ADB didn't make my phone visible for QPST. And I also tried while in recovery, download mode, and all the other settings in the *#0808# menu, plus variations of the menu and then booting into recovery, normal boot, and download mode. All to no avail, then in frustration I tried the following and it's gotten to the point I can't see my phone via adb anymore. So could someone please give me the undo set of commands for typing into my phones terminal as I can't type them via my computer due to adb not seeing it anymore? Thanks
C:\Users\xxxxx>adb devices
List of devices attached
0123456789ABCDEF device
C:\Users\xxxxx>adb shell
$ echo MODEM USB > /sys/class/sec/switch/usb_sel
echo MODEM USB > /sys/class/sec/switch/usb_sel
cannot create /sys/class/sec/switch/usb_sel: permission denied
$ su
su
# echo MODEM USB > /sys/class/sec/switch/usb_sel
C:\Users\xxxxx>adb shell
error: device not found

Oh!, and if anyone can explain either what the commands did or better yet where I can go read about such commands and what they do that would be great too. Thanks

Not sure how relevant this is or if it will help you but this man seems to be in kinda the same boat, why don't you take a look at this thread particularly post #2 http://forum.slimroms.net/topic/2008-broken-usbuart-path-causing-loss-of-adb/

Thank you for the link I haven't tried anything based on the information yet, actually haven't read it all yet. Very complex stuff just lets me know how far I have to go. Odd thing is that I now for some reason have ADB working again. I did a factory reset recently and the other day I reinstalled/refreshed my computer. My computer was infected by a bunch of viruses and malware the phone was just sluggish and I had way more apps I wanted rid of than to keep. Anyway, I don't know if the virus on my system had anything to do with the malfunction or if it was the command I used but for now it is back to working.
I was working on a friends HTC Desire and was having a hell of a time getting fastboot commands to work. I got hboot USB working but when giving a command it would generate a "device connected toi USB has malfunctioned" also the USB ports would shut off untill reboot too intermittantly and even my wifi three or four days ago became disabled and I reset the adapter fine for 5mins then it went a level deeper and deeper till I reinstalled the driver. That being said it is more likely that it was the virus and or the person messing with my system that was causing all the grief. They even triggered email alerts on a couple of my accounts that passwords were input wrong 5 times in a row and that some security settings were being changed. Hopefully I have dealt with that if not I'll have to wait till they get bored. Sorry if that was a little off topic it sort of conencts to my recent problems.

How to get into Qualcomm diagnostic mode?

Hello there.
I have been having the 'stupidly set baseband to USA and unable to change back' issue with my Nexus 5x, using a European version. I live in Croatia, so as you would imagine this has meant a complete loss of signal/mobile operator/3g etc.
As per my other thread in Nexus 5x help and troubleshooting,
http://forum.xda-developers.com/nexus-5x/help/usa-baseband-set-european-model-t3252879
I have exhausted other options and have come to the realisation that as per other users issues with other phones that the use of QPST tools and using a clean QCN file to inject into my phone is the only course of action left. However, I have no knowledge of such things (not to say that I am unable to inform myself).
I emailed a developer with regards to users issues with Nexus 5 phones (not 5x), and he said that I need to enter this mode on my phone.
Could anyone help me out with this, and in general with this issue? As some have tried to help but unfortunately my thread has more of my own replies than other users. (In elaborating on steps taken to resolve my misery).
I am not looking for a 'one button fix', I have educated myself far and beyond with regards to this issue, I just need some more expert help so that I can sort this out myself.
Please, anyone?
Marko

Thank God.
I can actually get a new phone. Help not needed in the end.
Thanks anyway.

glad you got your probelm fixed dont know if this will help you or others but if you press *#*#4636#*#* your phone will enter a radio diagnostics tool where you can set your preferred network type and also select your radio baseband by using the 3 dots at the top. For my 5X i can select USA BAnd or Band mode 6, Band mode 7.
sorry if this is OT and not related to your issue.

Thank you for your input. However my phone does not have those options. Only USA band, which led to this week long stress for me. Im going to be able to get a replacement device in the end, so im happy about that, but this issue is unfortunately somewhat of a one way street wherin the usual simple solutions or even more complex adb, fastboot, etc etc things do not bring about any resolutions.
Again, thanks for trying to help but its a phone to phone kind of thing.

Best advice ever...
But.... If you are really hot on getting the 5x into diagnostic mode to run QPST, QXDM, etc., do this. (I did this on my 5x to obtain the QCN file to check out the NV and EFS items, grab QXDM logs, etc.)
1. Use Heisenberg's most excellent step-by-step tutorial on unlocking the boot loader, rooting the phone, and installing super user apk.
2. Once rooted, connect the phone to a PC and open up adb, then issue the adb shell command.
3. Once in adb shell, type: su -c 'setprop sys.usb.config diag,adb'
4. At this point, you should see a pop up on the phone to authorize super user access. Click to allow access.
5. Now you will probably have to load a driver on the computer for diag access. I got lucky (since I have a mess of drivers on my computer) and the driver loaded automatically. As I recall, my computer selected qcusbser.sys. Seems to be a pretty generic QCOM driver vs. an LG specific driver.
6. You now have diag access. You will have to run steps 2 - 3 after each phone reboot. In other words, these steps aren't "sticky" between reboots.
7. ????
8. Profit
I did this and it worked for me.

HTC M8: Root, virus, ripped off £26.68 & then tele view fraud! Please help, how hard?

HTC M8: Root, virus, ripped off £26.68 & then tele view fraud! Please help, how hard?
I have decided to keep my HTC M8 and go sim only to avoid another 24 months of contract. Today I sim unlocked and bought my new network sim. I have enabled USB Debugging and Developer options.
Then I set about trying to root the phone - the primary reason so I can delete all the Vodafone and HTC bloatware now I'm out of contract.
So I tried the hasoon2000 thread on here, which ended up with AVG going mental at all the viruses/adwares/trojans I'd installed. After sorting all that out, I found onelclickroot.com online. It seemed too simple, it was. I paid £26.68 and it didn't work. Chat comes up and a guy offered to teleview my computer screen to do the job! I don't believe this can be genuine... Is it?
So... Please can anyone tell me how I can root a British, Vodafone HTC M8 in reasonably simple steps that someone who's pretty new to this can make work without wrecking their PC and phone!???
Many thanks,
Al

Don't see any further post from you, don't know whether you still interested doing what you want to do.
Most important - post fastboot getvar all result without serial & imei no. for a start
What you need :
Install fastboot/adb - http://forum.xda-developers.com/showthread.php?t=2317790
Install HTC Sync Manager for the latest HTC USB drivers - download : http://www.htc.com/us/support/software/htc-sync-manager.aspx
after installation is completed, uninstall HTC Sync Manager but leave the drivers (don't uninstall)
Open a command prompt then type - fastboot getvar all

Hi - Thanks for the info. I take it that my phone is plugged in during this process, and what state will it be in once I've typed "fastboot getvar all"? Thanks.

on bootloader/fastboot screen.
You have a good running device, right ?
go to settings - about - software information - more - build number - click on it 7 times to enable developer options
then settings - developer options - tick usb debugging
connect phone to PC, open a command prompt then type -> adb reboot bootloader
this will boot the phone to bootloader/fastboot screen - you should see fastboot usb (in red)
then type in command prompt -> fastboot getvar all (post the result here (minus serial & imei no.)
to reboot it back to system, use volume down button to scroll to "reboot" and power button to select

NO. Getvar data is just giving us the basic information to get started helping you out.
Hasoon's toolkit just gives false positives for malware, it should be okay in that regard (assuming you used a reputable download source - for instance links from reputable XDA members). However, its very obsolete, having not been updated for over a year (going on 2 years) and therefore won't work on my current devices.
You never should have spent money to root the device (s-off by sunshine yes, but just to root, NO). Everything you need is available here for free. Even if the service was legit, its just a waste of money and you are cheating yourself. One click root methods never work for HTC devices, either. So any claim otherwise, is not to be believed.
Post the requested info. and we'll get you started sorting you out. My advice is to read and learn properly, and that is always a better idea than trying to take shortcuts like "one click" roots.

I think maybe google disabled this,I also want this

For Generic HTC devices,such command with root shell may could open the DIAG PORYT
echo 1 > /sys/devices/virtual/android_usb/android0/f_diag/func_en
But Google AOSP HTC devices....................
Someone has already solved this Problem but due to the negative attitude of the USERs of PIXEL,so.....................

Looking for the answer to this as well. It's needed for DFS and QPST (QXDM).
Every phone has some particular way to do this and so far I haven't found it on this phone. The Nexus 6 was super easy and I was hoping this one would be too. (On the Nexus 6 all you had to do was select BP Tools from the boot menu. Then it booted like normal but with the diag port enabled. Other phones you have to write to or create a particular file, or there's a dialer code but the usual tricks aren't working here.)

Oh crud, I just noticed I was replying to a Pixel XL thread rather than a Pixel thread. You'd think they'd be similar.... does your method work on the Pixel XL, though? If you've tried that and say it works I may actually switch, if I can't figure out how to connect this Pixel.
When I try this on the Pixel (sku G2PW4100 running 7.1.1) I just get "Permission denied", even as superuser, even after changing the f_diag folder permissions to allow writes.
You're getting it to work on the G2PW2100, I guess? 7.1.1?

I apologize for not specifying that I don't have a Pixel or Pixel XL yet.
I know the command I posted above works on the HTC m8. I had almost given up on diag mode on that device until I tried that command.
It sounds like you're on the right track, but unfortunately my understanding is fairly limited. Hopefully somebody with more knowledge can chime in.

I've never messed with this, but I'm looking through the history here to see if there's a clue.

- Makes sure you are rooted. <-- *If you are not and do not know how, Please do your research*
- Download and install the GalaxyTools3.1.2 app
- Tap the GalaxyTools3.1.2 App, grant it Super User permissions
- Once you are in the GalaxyTools3.1.2 app scroll down and tap "GTUSBItil" Button
- This will open up the "UART" Menu which you should be able to use to select DM+Modem+ADB

Have you tried the "hacked" HTC Modem driver? If you get a list of Unknown devices in Windows Device Manager, you may be able to get install the modem driver and get QXDM or DFS working.
Let me know if you need any of those files.

Hi,
I am desperately looking for the solution for enabling diag mode of Pixel XL phones. Any update regarding this would be very helpful.
Thanks.

I tried to build a userdebug build from AOSP but I didn't get very far (first attempt at it, and it kept failing after 1-3 hours).
So cancelled that endeavor and installed the latest Lineage from InvisibleK which was built as userdebug.
>adb shell
>su
>setprop sys.usb.config diag,adb
PC tried to install new drivers (as expected since it has a different vendor/product id). Qualcomm HS-USB Diagnostics 903D (COM14) showed up under Ports. Unknown ADB Interface couldn't install drivers, though. All the tools seem to be working fine.
I have to quit for now, but hopefully that's a start for you.
I wanted to build the stock build as userdebug because that's how you get the diag USB modes enabled. They were stripped from the -user builds.
Edit 1: Phone shows up in QPST now.
Edit 2: Phone shows up in QXDM after setting Target port in Communication setting.
Edit 3: I am not sure if I had installed the drivers linked in this thread, already. The driver version I have is 2.1.04

If someone can install a non-T-Mobile SIM and let me know what their NV 65538 is, I'd appreciate it.
Edit: This value did not change with a Cricket Sim in versus a T-Mobile SIM.

[Guide] Enabling VoLTE/VoWiFi v2

Preface
With this guide I can officially deprecate the other guide I wrote, as we will no longer have to hack together a solution by loading profiles for other carriers. Meaning, that this should just work provided an mbn exists for your carrier - doesn't matter from which device. This has been reported to work on TMO in the US, which did not work with my other method.
Prerequsities
* You must have working DIAG mode. See my other thread for more information on how to set that up.
Downloads
* AsusVoLTE v1.0.1
* EfsTools 0.10 modded 1.2
* EFS items
* Xiaomi Mi 9T MBNs (optional)
Step 1 - setting props
Install the AsusVoLTE app from above, make sure to upgrade if you already have it installed. Run the app and press the Enable VoLTE button; this should set some properties on the device to force-enable VoLTE after we have also done the other steps below. If you already enable VoLTE using my old method you can safely skip this step.
If you prefer to not use the app, simply run this in an adb shell:
Code:
setprop persist.vendor.dbg.ims_volte_enable 1
setprop persist.vendor.dbg.volte_avail_ovr 1
setprop persist.vendor.dbg.vt_avail_ovr 1
setprop persist.vendor.dbg.wfc_avail_ovr 1
If you are unable to set those properties for whatever reason, like if you have returned to stock after flashing the mbn and no longer have root, there is another possibility to force VoLTE/VoWiFi; There's a secret code you can use to force-enable it, but unfortunately it does not survive a reboot (not sure why ASUS didn't make it persistent).
Enter this in the dialler:
Code:
*#*#3642623344#*#*
The number will clear itself, and you shouldn't see any output if it succeeded.
When you have done this, go to (System) Settings -> Mobile network and toggle Mobile data off then on again. You should hopefully see the VoWiFi or VoLTE icon in the status bar now, but like I said above you will have to redo this if you reboot the phone - so if you can, please use the properties method instead.
Step 2 - making sure it works
Before we begin, make sure you close down QPST, otherwise EfsTools will error out because there can not be two clients connected at once.
Unzip EfsTools from above, open up a cmd window and cd to the directory where you extracted it. Depending on how you connect to diag you will need to modify EfsTools.exe.config - if you're connecting via USB you most likely won't have to do anything as it will find the port automatically, unless you have more than one port, in which case you can simply change port from Auto to the COM port of the phone (for example COM13).
If you are connected via wifi you will need to change port to 2500 (or whatever port you used in the AsusVoLTE app) and remote to true. So the efstool line should look something like this:
Code:
<efstool port="2500" remote="true" baudrate="38400" password="FFFFFFFFFFFFFFFF" spc="000000"/>
You can test the connection by running this in the cmd window:
Code:
EfsTools.exe efsInfo
This should report back some info if everything is working. If not, try rebooting the device and redo the bits from the DIAG guide.
Step 3 - disabling mcfg
Extract efs.zip from above to the same directory as EfsTools.exe, and make sure the mcfg_autoselect_by_uim file is there. Now simply run this in the cmd window, one line at a time:
Code:
EfsTools.exe writeFile -i mcfg_autoselect_by_uim -o /nv/item_files/mcfg/mcfg_autoselect_by_uim
EfsTools.exe writeFile -i mcfg_autoselect_by_uim -o /nv/item_files/mcfg/mcfg_autoselect_by_uim -s 1
If everything worked you should see no error messages.
Step 4 - writing mbn
If you are using the Xiaomi Mi 9T mbns zip from above, move it to the EfsTools directory and extract it. Now we simply need to find the mbn for your carrier.
The mbn directory structure is generally laid out like this: <region>/<carrier>/commerci/<country>/mcfg_sw.mbn. For example, the one for my carrier is eu/h3g/commerci/se/mcfg_sw.mbn. Copy the mcfg_sw.mbn file to the same directory as the EfsTools.exe, then go to the cmd window you opened and type this:
Code:
EfsTools.exe uploadDirectory -i mcfg_sw.mbn -o / -v
To get it working on the second SIM slot you will also have to run this:
Code:
EfsTools.exe uploadDirectory -i mcfg_sw.mbn -o / -s 1
If it has worked you should see a bunch of output, but no errors. Try rebooting now, and hopefully after it has booted you will have fully functional VoLTE and VoWiFi.

Let me know if this works for you, or if you have any questions.

I cannot for the life of me get either method to work. Connected via USB. DIAG mode driver is loaded on COM1, even changed Baud rate on the COM port in device manager to 38400. USB method gives me "Critical Error: Bad Command" Remote method does not send any information but indefinitely runs. I'm really not sure what else to try. Im on the latest WW Firmware with Magisk root. Is there anything else I can check? Are you on the 8 GB Tencent version?

Is COM1 the only port available? What does it identify itself as in Device Manager? It should be a Qualcomm ... 902d device.
I'm on the tencent version, yeah, so it should be working for you as well.

I changed it to that, I'm even trying this on a completely different computer to see. Now its on COM3 on the different system with that driver. I even recently did a full WW firmware flash and factory reset as well. So its pretty much completely stock other than Root and the Apps you made / modified.
Still, Critical error. Bad Command when running efsTools efsInfo
What version of the driver does it say for you?
Edit: When you're able to access efs, What does your sys.usb.state say? I have rndis,adb shown but sys.usb.config is set for rndis,diag,adb. Does your sys.usb.state have diag included?

Thank you so much for your work on this though! It is nothing short of amazing.
Does it matter which USB port we use on the device? I've tested both the bottom and the side and neither are working.

Critical error. The requested resource is in use.
I keep getting the following error and I'm not sure what the cause may be. Is it possible that a video tutorial could be made to help out in beginning as I'm not sure what I'm doing wrong on my end.
Thank you so much for your work on this though! It is nothing short of amazing.
Does it matter which USB port we use on the device? I've tested both the bottom and the side and neither are working.

Make sure you dont have QPST server running. Its not required if using the tools. I ran into this issue and realized thats what it was that was using it.

How do I make sure the server is not running? I've rebooted and checked but I'm not seeing anything/indication of it doing so. Thank you in advance!

Open up QPST Configuration > at the top click Server > then Stop QPST Server. After that, see if efsTools give you anything. (efsTools efsInfo)

Hrmmm still not working on my end. Not sure what I'm doing wrong but I'll give it a rest for the time being.
My qserver keeps saying that it cannot find my USB or phone either. So I might be missing something. I'll Uninstall and try again though

What does it say for you? It won't find it if you turn it off. What is the COM port / driver that shows up in Device Manager

I changed it to that, I'm even trying this on a completely different computer to see. Now its on COM3 on the different system with that driver. I even recently did a full WW firmware flash and factory reset as well. So its pretty much completely stock other than Root and the Apps you made / modified.
Still, Critical error. Bad Command when running efsTools efsInfo
What version of the driver does it say for you?
Edit: When you're able to access efs, What does your sys.usb.state say? I have rndis,adb shown but sys.usb.config is set for rndis,diag,adb. Does your sys.usb.state have diag included?

Could you try this updated EfsTools: https://github.com/HomerSp/EfsTools...modded-1.1/EfsTools-0.10-modded-1.1-win32.zip Hopefully it should work for you.
sys.usb.state is supposed to say just rndis,adb - diag will only be listed in sys.usb.config.

Preface
With this guide I can officially deprecate the other guide I wrote, as we will no longer have to hack together a solution by loading profiles for other carriers. Meaning, that this should just work provided an mbn exists for your carrier - doesn't matter from which device. This has been reported to work on TMO in the US, which did not work with my other method.
Prerequsities
* You must have working DIAG mode. See my other thread for more information on how to set that up.
Downloads
* AsusVoLTE v1.0.1
* EfsTools 0.10 modded 1.1
* EFS items
* Xiaomi Mi 9T MBNs (optional)
Step 1 - setting props
Install the AsusVoLTE app from above, make sure to upgrade if you already have it installed. Run the app and press the Enable VoLTE button; this should set some properties on the device to force-enable VoLTE after we have also done the other steps below. If you already enable VoLTE using my old method you can safely skip this step.
Step 2 - making sure it works
Before we begin, make sure you close down QPST, otherwise EfsTools will error out because there can not be two clients connected at once.
Unzip EfsTools from above, open up a cmd window and cd to the directory where you extracted it. Depending on how you connect to diag you will need to modify EfsTools.exe.config - if you're connecting via USB you most likely won't have to do anything as it will find the port automatically, unless you have more than one port, in which case you can simply change port from Auto to the COM port of the phone (for example COM13).
If you are connected via wifi you will need to change port to 2500 (or whatever port you used in the AsusVoLTE app) and remote to true. So the efstool line should look something like this:
You can test the connection by running this in the cmd window:
This should report back some info if everything is working. If not, try rebooting the device and redo the bits from the DIAG guide.
Step 3 - disabling mcfg
Extract efs.zip from above to the same directory as EfsTools.exe, and make sure the mcfg_autoselect_by_uim file is there. Now simply run this in the cmd window, one line at a time:
If everything worked you should see no error messages.
Step 4 - writing mbn
If you are using the Xiaomi Mi 9T mbns zip from above, move it to the EfsTools directory and extract it. Now we simply need to find the mbn for your carrier.
The mbn directory structure is generally laid out like this: <region>/<carrier>/commerci/<country>/mcfg_sw.mbn. For example, the one for my carrier is eu/h3g/commerci/se/mcfg_sw.mbn. Copy the mcfg_sw.mbn file to the same directory as the EfsTools.exe, then go to the cmd window you opened and type this:
If it has worked you should see a bunch of output, but no errors. Try rebooting now, and hopefully after it has booted you will have fully functional VoLTE and VoWiFi.

Let me know if this works for you, or if you have any questions.

Absolutely genius, your work here is greatly appreciated everything is working perfectly VoLTE and VoWiFi with caller display
I used the EE mbn included in the Xiaomi Mi 9T MBNs provided , So for anyone on EE i can say it works without a problem.
Thank you :good:HomerSp

in device manager it shows up as
Qualcomm HS-USB Android DIAG 902D (COM13)
EDIT: It started working oddly enough. Which mi9 file would I flash for tmobile USA to test?
Thank you in advance for this!
Edit 2: got it working! Had to Uninstall, reinstall qpst, open up app and click enable DIAG, then stop the server in qstp and input the commands and it worked!

Thought so, just wanted to make sure.
https://imgur.com/a/WZvKteM is what I get. Is it possible to go back to an earlier RAW rom? I want to see if theres something in earlier ROMS that will make it work. I'm just at a loss. I'm not sure what I'm missing for this to work.

@HomerSp, thanks so much for all your efforts and skills - works a charm on ee UK using Mi9T MBN's

I cannot for the life of me get either method to work. Connected via USB. DIAG mode driver is loaded on COM1, even changed Baud rate on the COM port in device manager to 38400. USB method gives me "Critical Error: Bad Command" Remote method does not send any information but indefinitely runs. I'm really not sure what else to try. Im on the latest WW Firmware with Magisk root. Is there anything else I can check? Are you on the 8 GB Tencent version?

Same issue as you, i had it working at the start then it just stopped altogether. Hoping a next asus update could reset whatever i did to it and retry it again

Mine is getting stuck on "Use serial port 'COM5'" and nothing happens after that. Any recommendations how to make it work?

I had to Uninstall qpst entirely, reinstall it. Then plug my phone in, open up the Asus volteapp and hit enable DIAG, my device then showed up in device manager, then I stopped the qpst server and it worked for me just fine. Using windows 10 with latest update.

Thanks for the quick response. My device is already showing in device manager with COM 6. I never installed QPST since is not needed for USB connection. QPST is not even mention on OP.

I want to say the first part says that you need to have DIAG enabled.

Which I think needed QPST installed. Unless I'm sadly mistaken, then please disregard!
