Nexus S and ICS a little problem

Hi all
I did not receive the OTA so I decided to manually update my nexus s (I9020XXK1)
Unfortunately the navigation works only on wi-fi. Although the data navigation is turned on the mobile does not download email etc.
I thought it was a problem with widgetsoid and I disinstalled it but the problem is still there.
I also tried to update the APN via "APN Italiani" but the programs shows the generic message that "he encountered an error"
My question: do you have any idea how to work it out? and also: is there a program similar to widgetsoid for a dummy (me)?
thanks a lot

just flash a customer rom like aosp + (http://forum.xda-developers.com/showthread.php?t=1397358) -> all works

it would be even worst! I already tried but I'm a dummy and couldn't do it
at home I have a mac and could not get a propor procedure. now (at work) I have a pc but no administrator rights.
if there is an easy way to do it then I will give it a try but I would need a "guide for dummies"

Rollback Optimus 4X HD from 4.1.2 JellyBean to 4.0.3 Stock ICS in this case V10H
Videotutorial: http://www.youtube.com/watch?v=NDyZ8pH2jp0
1st: U need are the files that you get here: LG FlashTool and Accessories

Disable Windows Enabler when its running from a season before with the KDZ-Update-tool! It wouldnt work!
Be sure you have the propper driver instaled and chosed the right options in the comport settings!

Easyest way...
To go back to previous firmware (ICS V10x_00) with LGFlash Tool there is no need to invent in device properties
or others...
The same methode can be used to do a clean install of the V20A, or other...
Internal memory will be wiped !!!
Be sure that you have the latest drivers installed:

install "msxml" (its inside the "kdz-update" folder).
run windows enabler and turn it ON
With battery on the phone and the phone off, press "VOL-" and connect the phone
to the computer while pressing, you'll be in S/W. (If you have issues due the device
being recognized while in S/W Mode, disconnect from PC, take out the battery and
put it back again on the phone, try again "Vol- & connect to PC", wait a few seconds
for Windows to recognize the device).
Run "LGFlashTool" (its inside the "kdz-upload" folder).

Go to "port settings" and select all 16 ports.
View attachment 1784756
Start the upgrade clicking in the yellow arrow on the top/left of the program window.
Three (3) ports will look like comunicating (in the next image you'll see only two cause I'm not really flashing), but
only one is the right one. Two of them will stay stucked in x% and a third port will go higher. Memorize the one that goes higher cause is that one.
In my case, this time was the nr. 3.
View attachment 1784757
Close the program and re-start it. This time, go to "port settings" and select only the port that you memorized,
start the upgrade and you just need to wait for the phone to reboot.
In case of that port fails, choose one of the other two untill you hit the good one.
If you don't see 3 ports, its something wrong and probably this won't work...
Easy
To set manually the port to "1", connect the phone in S/W Mode, open windows "Device Manager",
select “LGE CDMA USB Serial Port”, right click in "properties", connection settings advanced and set it to “com41″
Video added:
(select full screen and 1080p for better resolution)
Report if something doesn't work
This post was edited cause I realise that is not always the first port the right one, sorry...

agree (see below)
I - Install APX (NVFlash Recovery) Drivers if not already installed. It starts a device driver wizard to help you install the drivers needed for NVFlash. It detects your system OS and gives on-screen instructions if running Windows 8. FYI the drivers are located under ToolKitFiles\nvflash\driver folder.

Prepare Phone
-Power down phone
-Remove battery
-Hold VOL_DWN+VOL_UP & plug in USB connection from computer (note, your phone will not visibly respond but it will boot to APX mode quickly)
-Open Device Manager in Windows and you should see "APX Device" listed with an error, or not if you have used NVFlash before
-Right click on the APX device
-Select 'Update driver software'
-Select 'Browse my computer...'
-Select 'Let me pick...'
-Select 'Have disk'
-Browse to directory you extracted the *driver* software to above (It's included in Stefan's zip)
-Select 'NVIDIA USB Boot-recovery driver for mobile devices'
-Accept any warnings, including the big red alert (you may need to disable UAC)
-Now in Device Manager under 'USB Controllers' you should have an 'NVIDIA USB Boot-recovery driver for mobile devices'
If not, uninstall the driver, reboot, rinse and repeat
Install the rom:
- Go to the folder where you unpacked Stefans rom
- Run Windows installer and follow instructions on screen, should be peace of cake for everyone!
- DONE

I think you should try either updating your drivers for the phone and if that doesn't work, try an older version then.

Windows will install adb drivers automatically once the phone is connected (depending on what mode).
Give time and let the "Windows Device Manager" do the rest.
If you want to try to unlock bootloader, thats another story...

those are fine. just force them in. whats the problem ? open the system manager , right click where u wanna install the driver, choose update , choose from pc, choose from list of programs, have disk, choose one whatever file in x64 or x86 depending ur windows version, choose the adb testing interface for android and u r done

is says the files are not for my sytem although right one

there are 2 ways to install the files. the one way sais it is not for ur system and the other way just force the driver in.
use mine if u want im on windows 8x64. but i tell u they are similar.

Try to let the Windows re-install the correct drivers.
Go to the Control Panel and open Device Manager (your device should be connected in charge mode only and debbuging ON),
you should see something like "ADB Interface" and "Android Sooner Single ADB Interface", right-click on it and choose "Update Software Driver"
(something like that, mine is in portuguese...). If it doesn't work, just uninstall it and "Search for Hardware Changes". Let Windows install it
from the Internet.
BTW, the driver location should be: "x:\Windows\system32\DRIVERS\lgandnetadb.sys"

another way that maybe works but is more like a "pro" way , is to install to your pc the whole android sdk. this will search for drivers on its own and install them. it will install the latest google adb which is also working. if u dont make it to force the drivers in, let me know to show u link to the android sdk ( easy to find though ** if u end up to sdk careful to download the x32 version even if u are on x64 and double check that u have installed the latest java jdk also x32 even if u r on x64 ! )

i have sdk already, it dont matter which adb interface i want to add from google it always has the exclamation
adt-bundle-windows-x86_64-20130917.zip

in your case i cant help any more. i told you exactly what to do. next step is if i was there to do it myself. ill try make some images to show you how i installed the drivers but it will be in greek. button and everything are in same place, only language will be different.

No OS installed, boots to TWRP but PC does not recognise device

So I've got a 3T which currently has no OS installed, just the TWRP3.2.3-0. The problem is that every time I connect the phone to the PC, the PC will only recognise the phone as Unknown USB device (Device Descriptor Request Failed). Due to this I cannot use adb to transfer files to the phone or transfer files directly to the internal storage.
I have tried using Minimal adb but device isn't found, tried different USB ports and cables too. For some reason the recovery does not read devices attached to OTG as I have also tried to transfer files using this method.
Any suggestions as to what I can do to make my PC recognise this device? Thanks

first of all check your usb cable then use this op3/t tool
it will install all drivers, unlock, decrypt, install twrp and dm-verity issue solution

But I cannot enable USB debugging since there is no OS installed, however I have not yet tested this program.
The USB port was working normally before the OS was removed. This problem started once there was no OS and just recovery. Is there truly no other way I can transfer the ROM to the phone? Thanks for your help

while having TWRP installed pc should recognize your phone, if encrypted phone shows Oneplus 3 in my computer Location without showing internal storage,
Check your USB cable, then boot into fastboot(Boot loader By pressing Power & volume up button together while phone is in off state) connect your cable to pc and phone and run the tool, to install op3 driver select number from your pc
install driver (1)
unlock bootloader (3)
decrypt(10)
install twrp (5)
boot into TWRP from fastboot screen select recovery and reboot
Push superSU (7) (it'll copy superSU into internal memory) install supersu otherwise phone lose root and go back to encrypted state and you cant see internal storage in pc
reboot into recovery and copy your rom, gapps and Magisk 17.1, install them
You are done now

Thank you for this information, however I get as far as installing the drivers but the PC still shows phone as Unknown USB Device (Device Descriptor Request Failed) and therefore the program does not find the phone. Tried this on two different PC's.

Go to advance in TWRP then click on sideload and flash the os using sideload command i. e. adb sideload filename. zip

Since the phone is only recognised as Unknown USB Device (Device Descriptor Request Failed) in the the win10 Device Manager, fastboot devices does not find any attached devices and I cannot transfer files through ADB.
I have tested the cable I am using with another phone and I was able to transfer files to the other phone using the same USB cable.

I have tried using USB OTG but the recovery does not detect my connected usb drive. Regarding sideload, when I boot to recovery and select adb sideload, and connect the phone to my PC I get a USB device not recognised message. The commands adb devices and fastboot devices do not list my phone.

Try this guide if your phone detects as Qualcomm in device manager then proceed otherwise check your charging port (type c port) as you mention usb otg didn't detected and usb cable worked with other phones.
don't forget to clean your type c port if dirty or rusted. :good:

I have tried to install the qualcomm driver but when I go to Device Manager -> Update Driver -> Have Disk and select the qcser.inf file I get the following message: "The folder you have specified does not contain a compatible software driver for your device. If the folder contains a driver, make sure it is designed to work with Windows for x64 based systems." I have disabled driver signature verification. No idea why nothing seems to be working.

Tried to connect a keyboard with otg and it did not work with this phone. It worked fine using the same otg cable on another phone.
