[Q] After Rom Update, Phone Cant Connect To Mobile

Updated my Rom last night to its current nightly version. Thought everything was good. Leaving for work the next day I notice I don't have ANY cellular signal. Thought it might have been the update so I wipe cache/ dalivk/ format system. Install older version of rom. Same thing happened. No cellular signal NOR could my phone activate. I went into my settings/ status/ and noticed everything had been nulled out to zero. My phone number, MIN, PRL, and Username. Any idea how I can restore this? I tried flashing several different roms but the same thing happens. I also tried unrooting the device and get stock rom to perform a system reset but that did not work. Any suggestions. I tried searching for a solution but couldn't find any. Thanks!

Thanks for the reply! I did that and still doesnt work.
Baseband: L710VPUDN8
Rom: Conquest-Singularity-9.4 (This is NOT the rom that caused the error!)

I finally got it! 8 hours of research and I finally got it fixed NO THANKS TO SPRINT -(shouldnt be a surprise really)
Anywho! If this happens to anyone, I hope this helps:
1) Downloaded and install the appropriate Samsung USB drivers.
2) Download and install the "freeware/demo" version of DFS
3) Put your phone in DIAG mode:
* phone -> ##DIAG# (opens Diag screen)
* Open "Qualcom USB Setting" menu and select "DM + Modem + ADB", hit "Ok"
* Select "CDMA Modem"
4) Plug your phone into your computer via USB
5) Open DFS and click the connections button (a plug) you should see your Samsung device listed.
6) Your phone should now be connected! Select your phone from the dropdown in DFS (upper left)
7) Enter your MSL/SPC in the left box and click the button to send the code, you should see an "Unlocked" success message in the console
8) Enter the device code "01F2030F5F678FF9" or "2012112120131219" in the PWD box, click the button to send the code, you should see another "Unlocked" success message in the console
9) You should be able to read/write codes at this point.
10) Once you correct your HEX/DEC, press the disconnect button. Then remove device from PC.
11) Go back into ##DIAG# and change your settings back.
12) Restart phone... Viola!
Hope this helps! Now I'm going to bed!

ok, so I have the same issue, and did lots and lots and LOTS of looking around, and this seems to be the only appropriate way to do this. HOWEVER, every time i try to connect my phone to dfs, it doesn't read it correctly, either with the msl or ignoring it, or any of the 16 digit passwords I've come across for s3 basebands. SO... I'm just wondering what rom/modem combo you used. I've come to the conclusion that using a different rom with the corresponding baseband will allow me to properly connect to dfs. help please?? lol... thatnks in advance

I know this thread is super old, just thought that id add that I was able to connect to dfs and nv tools with cm11 and nfc baseband. Worked right away, was able to pull all the needed info/files, and get my spc without contacting carrier [emoji14] then just reflashed wicked x

[Q] USB Debugging mode blocked by Server?

Alright, heres a new one boys. I recently updated my US Cellular G3 to 5.0, and wanted to root. The first and only problem I have is when I go to allow debugging, the tab is grey out and underneath it says, "USB Debugging is disabled by server policy"
What can I do to change this? Any advice would be appreciated.
Thanks!

I have same problem when the G3 ìs plug on the pc , is it the case for you here ? If yes unplug your G3 and then you can activate debugging

Solution 3 : Test the differents options (PTP, MTP, ONLY CHARGE) and each time try to activate Debugging mode when you plug to pc
Solution 4 : Go to this menu and select program install then try to activate debugging mode
Solution 5 : Revoke the authorizations and try to activate the debugging mode

Just did a factory reset-Same result. I could understand them blocking this to protect against root (I wonder why LG and US Cellular are so against it), but what if I was actually a developer wanting to use SDK or make an app? It kind of ruins that feature. Any other suggestions?

And by flashing kdz firmware ? Il seems thant the update by OTA to 5 which is the cause of your problem.
Can be that by installing KDZ firmware you have this function ...
When you are on KitKat can you activate debugging ?
Type here your imei to have the lastest version of kdz : http://www.lg-phone-firmware.com/index.php?firmware=1

I tried installing the KDZ though TWRP, but when it failed I decided to go ahead and just update it with the LG Software. I had read other articles on rooting the G3 with Lollipop, so I didn't really worry about re-rooting it until I ran into this problem.
For installing with the KDZ, I extracted Modem, Boot, and System.imgs, but the System.img failed. And yes with KitKat, I could use debugging.

facing the same problem myself, did you ever find a solution? because this is getting really frustrating

Update, I made a post over on the US Cellular forums and if anyone is having this problem it is the McAfee bundled in with the new lollipop update, just find the McAfee app (you can't uninstall it without root) clear the cache on it and click the manage space button and it'll ask you to put in your pin to deactivate it, after I did that my debugging is back!

For those folk who are not as technically proficient I have laid out your instructions.

If anyone is having this problem it is due to the McAfee Security App bundled in with the Lollipop update, you can't uninstall it without root but if you clear the cache on it and manage the space you will get debugging back.
Go to "Setting"
Go to "Apps"
Select the "All" Tab
Select the "McAfee Security" App
Click the "Clear cache" button
Click the "Manage space" button
Enter your PIN
Click "OK"
Your debugging option will now be available.

To Enable USB Debugging mode that is blocked by Server you have to dissable McAfee Mobile SECURITY

Click on revoke USB debugging authorization. Click ok. Turn off developers option on the verg top. Turn it on again and voila you now have an option to put a check on usb debugging. Hope it works for you...

PLEASE PLEASE PLEASE READ! This is probably the fix to this problem all because of a stupid built in app that the g3 includes now and it has to do with McAfee Security.
If it worked mark this up for those future people who have issues!!
Okay so i found out what the problem was. I used to own and lg g2 but recently got the g3. Im with sprint fyi...but anyways i was tinkering around with it being 17 and stupid i bricked the phone, so i eventually got it fixed again. Previously my phone was rooted but now it wasnt so then i went back to get developer options activated and usb debugging active as well, however i ran into this problem. This stumped me because i had it rooted before. So then i was thinking what did i give accsess to that i hadnt before that isnt allowing usb debbugging...well it had to be an app since this didnt happen to me before and it had to be an app that i hadnt used before i bricked my phone and then i thought it has to be a built in app since no third party app would have that permission to say something like "disabled by server policy" then i realised okay what does the g3 have that the g2 doesnt have and is built in.....Mcafee security and Lookout! And it made sence because when you check the box for usb debugging you are making your android less secure! So i entered the McAfee app tapped settings ---> and the first option should be "lock down device" TURN THAT OFF! That right there is your culprit now go back to dev options and you can now enable usb debugging again please rate this up so people can see what was going on and how to fix it. No need to reset your phone. Also let me know if this worked. I have got nothing but positive feed back so far.

I am having the same problem and i have an LG Lucky and usb debugging is disabled by server policy and i really dont know what to do but it worked at first then later it got blocked.

help please

My debugging option is not available. Do I need to have my old sim card in place? It was from at&t. I took it out a while back. Is that why I cannot chose the Debug option? Ive tried everything on this forum.

I had the same issue. It was blocked by mcafee. I had to change it from " locked down mode" to unlocked mode, then turn developer options off and right baxk on. Then i was allowed to turn on usb debugging

Solution
Okay, so I was having the same issue. I contacted LG, Google, and finally AT&T after I tried a lot of the suggested solutions on this post. The AT&T tech support rep helped me research this issue. The issue is that an app on your phone is not allowing you to be able to debug, most likely a security app. I suppose that it thinks by allowing your phone to debug could cause harm to the device. The app that was keeping me from debugging was McAfee, which came pre-installed. When you disable this app, or whichever app is keeping you from debugging, you will then notice that the message 'USB debugging is disabled by server policy' goes away. I hope this helps you all, and happy developing!
God is good!!!

sir can you all help me for this problem? i can't update and fix my g3! ugrrrr !!!1

[HELP] Bypass PIN's phone lock and recover Google's account WITHOUT Wifi/Mobile datas

Hello friends,
Finding no solutions on the Web and on XDA, I need to ask you one thing :
A really close friend of mine passed away on july 13th after a damn f*cking brutal and quick heartattack. (He did'nt have time to take his phone to call emergencies) :'(
His family tried to unlock his phone to call some of his friends, to get some contacts , recover photos, etc... but unfortunately they could'nt unlock his phone because of a security PIN lock.
I know his SIM Pin code, so I could unlock the SIM to answer his phonecalls.
I know all of his passwords (Google, Gmail, etc...).
The problem is that I couldn't bypass the screen lock and recover thru Google's Account Recovery because he cuts WIFI & MOBILE DATAS (he follows my advice to save battery ).
I tried to bypass using the Quicknote trick (that allowed me to activate WIFI & BLUETOOTH), but unfortunately it couldn't connect to my WIFI (unlocked)...
Any clue ?
NO, I'm not a thief, a robber, a delinquent, so I didn't steal that phone. (Me and my wife are owner of 2 G4)
Feel free to ask me more infos/proofs via PM.
Thanks for your help and for his family.
Note : the phone isn't rooted and I don't want to do it because I don't want to wipe his (and it's) memory.

No one can help me ?

Did you check this out?
http://forum.xda-developers.com/g4/general/bypass-google-account-lg-g4-tool-t3261627

Thank you for your answer Jobella.
Why should I bypass Google account ? :/
I need to recover the PIN, so I need to connect to Internet. But unfortunately, data is off (Wi-Fi seems to be on, but doesn't connect alone to a free hotspot...), so I can't recover it.
Any clue ?

After I posted I realized you needed to bypass the phone lock screen and not the google account password. My mistake.

does ADB detect the device? if so, you can boot into TWRP (no need to install) and delete lock files.
adb reboot-bootloader
fastboot boot "path of twrp recovery image" (ex. fastboot boot "c:\twrp.img")
once TWRP is booted, go in advanced/data/system and delete followings
password.key
pattern.key
locksettings.db
locksettings.db-shm
locksettings.db-wal

reboot the phone, and screen lock should be gone and swipe to open.

if adb is not enabled you can't enable it with out unlocking the screen.
What about android device manager? I think that should let you lock the phone with a password you set. forgot you said you tried that.
Do you know any wifi networks he had it set to auto connect to? I think your best bet is to try to recreate one of them with the same ssid and wpa password so you can use android device manager to change the password.

SH*T ! That was the solution !!! I read it too late : finding no solution, I performed a factory reset ! :crying::crying::crying:

Tanks for your help !

This device is locked

Hi, I'm having some problems with flashing back to MIUI Rom.
Here is my situation:
I flashed a while ago to Xiaomi.EU rom.
Everything was working pretty well but I missed the "google-way" so I decided to try the PixelExperience Rom.
I did a full wipe for installing this rom. Was pretty satisfied but suddenly the wifi stopped working.
Also the performance in games was not that good.
Next i have done a full wipe again & installed the xiaomi.eu rom.
But when I enter the installation screens of the rom Miui will notify that my device is locked.
I need to enter my mi account password but it cannot verify it because I have no internet connection on my sim (I can't enter pin-code).
I can search for wifi networks, but the screen doens't give me a keyboard to enter the wifi password.
The screens says that I can unlock my device with i.mi.com (Mi cloud).
I tried a lot of things, deleting my 'phone', turned off find device but nothing is helping.
Next i'll tried the official global dev rom. Same problems!
Is there any way to get it unlocked by a god damn webinterface?!
I'm now back at PixelExperience with a few bugs.
Not my picture but this is simular, I also get a button to connect with WIFI but can't enter password...

You can try older Xiaomi eu rom, wait for awhile for the keyboard to pop up.

I fixed this problem...
I downloaded the Official China Stable fastboot version of my phone (Mi 6).
I flashed this with MiFlash.
First boot... No device is locked!
I installed the phone quickly because it was a chinese bloatware rom.
Next I flashed twrp in fastboot mode.
Booted in TWRP, Format data & copy the Xiaomi.EU version to internal storage.
After installing this rom in TWRP it booted with "Device is locked..." FUUUUUUUUUUUU
But now I was able to fill in the wifi password!
With a wifi connection you just have to type your password of your Mi account and all problems are gone!

Simple solution
I had the same tonight, first time i change my rom on my mi mix2 and found a simple solution:
Go to activate this device, and click on the "eye" to see the password you will type.
Type your wifi password here and copy it (long touch on it)
Then go to the wifi section and paste your password !
It's OK you're connected

Something similar happened to me, from one moment to another the Wi-Fi worked, I did a full reset and when I turned it on again the device gave me it was blocked, the button opened the button and told me to enter my password I did, but it turns out that never validate apparently still with the problem of wifi, suggestion?

Enter wifi routers admin page (192.168.0.1) or similar like this. Delete wifi's password and bum ! You can connect wifi without buttons.

Thanks Bud

fu*king genius! You saved my life!
But still I'm curious why I had this situation. I tried to install twrp, after success fastboot flashing I rebooted my phone a Mi-recovery 3.0 appeared. So no install any kind of zip. So reboot again and this "device is locked" showed up!
Any opinions?

Hi ppl. I have similar problem with my Redmi 5 Plus phone. I used the phone one day, I activated Mi account, I made transfer data from my old Mi 3, I unlocked bootloader succesiful, and then I installed MIUI 10 (developer version). After phone is booted I got screen with Device is locked. I have full access to my Mi account via web, but when I try to unlock device it says Invalid username! There is my conversation with Xiaomi global support. Then wasn't useful for me I am using custom RR rom, but I want to back to MIUI. What I need to do?

Thank you so much, worked well. Tryed to downgrade to miui 9 from miui 10 and got phone lock. Your solution was the best

I had the same tonight, first time i change my rom on my mi mix2 and found a simple solution:
Go to activate this device, and click on the "eye" to see the password you will type.
Type your wifi password here and copy it (long touch on it)
Then go to the wifi section and paste your password !
It's OK you're connected

[Guide] Enabling DIAG for QPST (updated)

Hi everyone, I have finally figured out how to get proper diag support on our device. This will allow us to use QPST and such.
It will be a pretty short guide as it's quite simple, but it does enable us to do a whole lot of things we couldn't do before.
Downloads
* QPST
* AsusVoLTE app
Prerequsities
* Both methods require root, at least initially. There are several threads on how to do that, so look those up if you need help.
USB method
Downloads
* Qualcomm USB drivers
Step 1
Install the drivers and QPST from above. If you've already done this from my VoLTE/VoWiFi guide there's no need to reinstall them.
Step 2
When you've done that, install the AsusVoLTE app and connect the phone to the computer and open up it up. Press the Enable DIAG button, and you should hear/see a new device attaching. This should hopefully be enough, but if not, try rebooting the phone. If that still doesn't work try the Remote method below.
Remote method
Prerequsities
* Both your computer and phone have to be connected to the same network. You may also need to allow port 2500 in your firewall.
Step 1
Start by downloading and installing QPST from the link above, no drivers or such required. If you've already done this from following my VoLTE/VoWiFi guide you can safely skip this step.
Step 2
Now run QPSTConfig.exe from the bin folder of the QPST install and wait for it to open up. Head to the IP Server tab and tick the Accept client connections box - we need to do this as we will be connecting to QPST remotely. Take a note of the Server IP Address (this should simply be the ip address of your computer), and potentially the Server Port below if you have changed it from the default value of 2500.
Step 3
Open up the AsusVoLTE app on the phone, and enter the IP address from the Server IP Address in the field, and optionally, change the port number.
After this you can simply press the Start button.
Now that you have done this, you should, momentarily, see a new port appear in QPST Configuration under the Ports tab with a Port number like COM30001 and the Phone column should hopefully say SDM855 (0). If you do see this you are good to go! You can now start exploring EFS and such.
Troubleshooting
Some people have had issues connecting to the diag port, with EfsTools from the VoLTE guide returning BadCmd and QPST not working either. If you have this problem, try restoring modem settings by running this in bootloader (adb reboot bootloader, or press volume up while rebooting):
Warning: This may cause issues with no service for some, do not run this without a full backup of all of the partitions (in particular, modemst1, modemst2, fsg and fsc) on the device!
Code:
REDACTED because people still run these commands without taking a backup
Do note that this will reset any changes you may have done (like enabling VoLTE through PDC).
Thanks to @xbamaris1` for troubleshooting this with me, and for confirming this worked!
Let me know if this has worked for you, and if you have any questions!

I'm getting this:
Code:
ASUS_I001_1:/ # diag_socket_log -a 10.30.1.10 -p 2500
diag_socket_log: Diag_LSM_Init succeeded.
diag: In diag_register_socket_cb, registered socket callback function
diag_socket_log: Translating address: 10.30.1.10
diag_socket_log: Trying to connect to address: 10.30.1.10, port: 2500
diag_socket_log: Error calling connect: Operation already in progress, errno: 114
I'll try to restart my computer and phone. Maybe there were some remnants of tools running still.

I had this problem to until I realized that its network based and your phone should be connected to your WIFI (at least thats what fixed it for me).
However, Despite this, i am still not getting data from it. COM30001 from an IP of 192.168.1.211 (which is my phone) and it is still not able to browse data from QPST

Wait, I think I got it. I had to use the USB tethering feature of my phone to bypass whatever my router's doing. I also had to run ipconfig to grab the IP address that was assigned to my computer, and manually set that in the "Use specified IP address" box.
Is this IP-based method necessary? I can already see my phone in normal USB mode.

Update: It turns out I didn't need the IP-based method as my phone's already seen through USB. I'm not sure how I managed that.

I really hope we can get QPST fully working. I'm in the same boat as you, was able to get SDM855(0) but nothing after that with QPST. Glad you got it to work though!
I really want to try enabling some LTE bands (just want two as a start, 12 / 17. And MAYBE 66.

Does your phone not show up as a USB device like mine? I wonder how I got it to show up. It would be nice to find out so it would be easier to use QPST.

Yeah it shows up as a USB device with SDM855(0) as the device. I actually had a different diagnostic driver that was the ANDROID Diag mode at some point, not sure if that was useful at all, but still no QPST data. Not sure how I managed to get the Qualcomm ANDROID Diag to show up (The exact interface / driver that showed up was: Qualcomm HS-USB Android DIAG 901D) it just magically appeared after trying to change the sys.usb.config at some point. Haven't been able to recreate it and not sure of the significance of it. But I believe QPST still registered it.

Try these drivers: https://androidfilehost.com/?fid=11410963190603864074
This is what mine shows up as after running "setprop sys.usb.diag2 1":

Thats what I have now, and usually do have when I enable it. I just thought it was strange when I suddenly got that other interface to connect. Again, not sure the significance of what I had since QPST still didn't work. But just was something I came across while trying to tinker.

It's not necessary, no - if you get it to show up in usb you won't need to do any of this. I could, however, never get the phone to connect in usb mode - it just shows as No phone.
I will try those drivers you posted and update the guide.

I've updated the guide in the first post - it now has both the usb method and remote method. I managed to get diag working through USB, but it seems to be a bit fiddly and sometimes required that I reboot the phone before it started working.
If you don't want to use the app to enable diag you can simply run this in a root shell:
setprop sys.usb.diag 2

How to change imei with EFS

QPST via remote using your guide worked for me. I am able to use EFS Explorer. Thank you @HomerSp!

Will doing this, to eventually turn on VoLTE and VoWiFi, lock me out of Google Pay and similar services?
Sorry if it's a stupid question, I've not toyed around with rooting since it began disabling pay and bank features that I have enjoyed using.

Magisk (the root method) hides itself from bank apps and such, but you can do a SafetyNet check in the magisk manager app, and if that passes so you should be good to go.
Only thing you won't be able to get with the bootloader unlocked is HD video in Netflix and Amazon video.

This is very interesting. I read in another thread that with nvram access you can try to enable bands (but it may not work). Is this to the point where that can be tried?

Yes indeed, but we have yet to find a way to enable additional bands. We are working on it though, so hopefully we'll have something soon.

Hi, can we use QPST to unlock LTE band on 8G/128G version?
