Hi I have just noticed in the nokia diagnostic tool in the bottom right the three dots when pressed gives you settings option and within that option it says usb mode Zune or usb serial with an option to choose which one ... What's this serial in this case ?? Will this allow direct access to hdd and find a way to use as mass storage ? or can we use this to access the cpu or other parts of the phone ?? im not sure were the serial point to yet ...
Probably that would be the way to flash rom.
It seems to be used for reparing the device or OS level software debugging - it won't give you USB Mass storage device....Or it maybe if you found the right driver...from Nokia Engineer. On HTC phones, this can be used for tethering with the right driver.
Serial Ports are the port that were used for Modem and Mouse before USB was invented (COM ports) It is the very basic form of communication port that most device implements - which the chipset on Lumia also emulate Serial Port over USB cable. (http://en.wikipedia.org/wiki/Serial_port)
Ahhhh ok thanks very much guys
Didn‘t notice that before, I'll poke at it using a serial debugger once I get home, could be some interesting/fun stuff that can be done
In winxp you can load a driver for a system device. maybe at driver level the connection data can be verified. How:
connect in serial mode. it will at first time detect a nokia rm801 or whatever device and ask for a driver. it finds 4 devices.
for the first, the xp system will itself suggest
1) USB Composite Device
2) will not find anything, and show the dialog to go onto internet, search etc.
Don't search and choose the driver to install yourself, with the downmost radiobutton and click next, in the categories go to System Devices, the driver assist will suggest a Compaq Deskpro Thermal Sensor, install this. Will install without error
3) see 2.
4) see 2.
Because it installs a temperature sensor driver, it must be possible to monitor or probe somehow. help?
My guess that will only gain you access to temprature data from the phone.
Have you tried putty and a baudrate of 9600? this is the most common used baudrate, tho It is quite possible they use 16000 instead if the serial connection is ment to handle data transfer.
I've been looking at the schematics for the phone and I can not seem to find out which chip they have used for GPIO. We would probably need to get hold of service level 3 or 4 manuals for Nokia Care (unless someone wants to dissasemble their phone and have a look at the mainboard)
Edit:
After a bit more digging I think I've traced serial to be managed directly by the CPU.
This suggests that it's a purely SW serial console.
I haven't been able to find any details on WP7/7.1/7.5 SW serial.
Worth looking into but I guess would require disassembly of the software?
what is the protocol for example when doing a software update through Zune? It gets into some kind of bootloader mode then too.
can imagine the serial connection is hosted as sw in the phones sw environment when running the mango os. But is the serial mode still fully sw if you boot it? Don't know if you could find anything in the 15 sec of booting to mango
I think the easiest way of figuring out how this is done is to disassemble the .net library that is used in the WP7 update tool.
I will have access to the required tools when I get home. The tool is this one if you want to get cracking on it:

I just received another KFHDX 7" to replace my old one.
Here's the situation:
- 1st HDX couldn't connect to Home PCs. One running Windows 8.1, and the other running Linux / Ubuntu.
- Talked with Amazon support and did all the listed troubleshooting techniques they told me to follow (most likely online "Google-ing" with me on the phone).
- My conclusion I told them, from what I think the issue can be, is that either there is a physical issue with the connectivity inside the KFHDX, or that a file corrupted when the battery died that is used to have the computer communicate with the PC.
- Amazon support gave up and sent me a replacement KFHDX 7" with firmware 13.3.1.0 on it. "Woo-Hoo!"
- 2nd KFHDX rooted and ready to go.
- Connected to Home PC to transfer files. Worked just fine.
- Connected to Work PC to transfer files. Worked just fine.
- Go back home to transfer files using Home PC.. USB issue. This time the KFHDX is giving me a different error message: "USB Compatibility: Some computers require a free file transfer utility to copy files between the computer and your Kindle. If you need this utility, please open your computer's browser and navigate to kindle.com/support/downloads. Your computer's USB port is a low output power source that will slowly charge your Kindle while asleep and may not charge while in use."
- Mind you I tried using both the front USB port on my Home PC (Win 8.1), back USB port on my Home PC (Win8.1), same USB cable, and different USB cables.
- Went back to my Work PC and it gave the same error, then.. some how it worked!
- Decided "Maybe uninstall the Kindle from the Device Manger utility", which I did, and left back home.
- Connect to Home PC. USB error message on KFHDX 7" device.
Any thoughts? Opinions? Also I really feel that a file was corrupted. If so I installed SafeStrap and Recovered my KFHDX stock ROM. Still had the same USB connection error as before.
Any files to download to the KFHDX to replace an old one? Or can I edit it myself using ES File Explorer?
If solved, tested, and my device can reconnect, I promise to give lunch/beer money for the one that fixes the issue. Thank you.
If it is beyond fixing then I will return it and wait until Google announces their next Nexus tablet in July 2014. Maybe as a "hassle-free" holiday college present. And hopefully similar or better hardware when compared to what the KFHDX has.
I'll also try to talk to my network admin that might have the Work PC with some kind of software where it makes this connectivity issue happen. I can download files off a cloud but USB is much faster and convenient.
.
.
Issue was solved.
My steps:
- Open Device Manager on PC
- Look to see if the Kindle Fire HDX is listed as Kindle, as if it is a device choice (Could be in Portable Device, if so expand it and you should see Kindle listed underneath).
- Disconnect KFHDX from PC. The device listed as Kindle should disappear.
- On KFHDX go to Settings / Device / Enable ADB and turn that off.
- Reconnect KFHDX. If I remember correctly the PC's Device Manager utility will label it as an Android Phone. (If not then sorry I can't help there. My first KFHDX 7" was giving me a different issue that I couldn't resolve. Amazon replaced mine after I tried all the troubleshooting techniques they gave me. Therefore this helps for those having this similar situation.)
- Now update drivers on the "Android Phone"
- Then out of no where my device could communicate with the PC again.
Hope this helps someone if you were having the same issue.

lol always look in device manager for the device it will load as two devices ,,,one as mtp the other as kindle fire, android usb adb device
Hey guys.
I have Samsung galaxy ace 5839i (stock for 5830i) and I am using it for a few years, but this problem came for the first time.
Always, when I try to connect my mobile to pc using cable, it just won't connect, it won't even show me the notification of connecting.
Before this problem, I connected it to fedora linux and it was succesful, but now? It won't show me that USB sign even in windows.
Any help?
Thanks in advance
@LiQuDiAk, basically s5839i and s5830 i are identical in many areas ,, few questions though,, did you root your device or you are on android 2.3.6 stock version / kernel 2.6.35.7 ?
when you are in your windows device manager ( while you are connected , do you see any exclamation / question marks in front of the corresponding driver), you can always uninstall your old driver, reboot , then try compiled driver in attachment , and reboot to take proper effect in your registry (tested on win xp/7 -32bit) . Also check your device settings>Application>Development > USB Debugging and make sure the option is checked. now lets check your debugging mode through ADB command and see if your device is being recognized. download platform zip attachment, unzip it and put the folder someplace like your desktop. Now open your command prompt (cmd) through whatever means you are comfortable and change directory (cd) to the unzip folder or simply open your folder and drag/drop adb.exe into your CMD to be in the right place very fast. Then type "adb devices" without quotation marks and report for more troubleshooting .Assuming your Samsung cable is not faulty of course.
@ehsanotaku Yes i did root my phone on pheonix fire rom. No i do not see any. And debugging is checked, that was my first guess why it was causing this. I was checking, whether my device is recognized in linux (only available OS in present) and it was NOT, but the cable is not faulty, because it was charging my phone... but i will do recognize process on windows, hope it will get better. But thanks so far!
so, the driver didnt help, but the adb devices got me something long which i do not completely understand (i am a girl and not IT) so...

off topic though, gender discrimination is prejudice,, sorry if you are offended . Learning from each other despite your gender,does not undermine your knowledge EVER mate You might find it hard to believe, but I am quite novice in android stuff myself ( learning a great deal from some female members though ).
Back to topic at hand now,,,So let Perfectly Clear take away the time-consuming tasks and fix some stuff ..1. so you can not access your sdcard's content from either systems,, even if you try some live bootable Ubuntu disk/flash into your system and boot it up,, you can't access the mount drive content , right?
2. screenshot of your device manger while you are connected always help mate
3. those long streams of numbers and words is supposed to be your device name , it means your device is communicating with your pc ( /sdcard/ should not be corrupted). You can push (copy ) some vital files to your device with following command :
again same path >> put some file into your desktop (drag/drop to cmd)
i.e: "adb push C:\Users\ehsanotaku\Desktop\test.txt /sdcard/"
back to your device and check root of your files with whatever file explorer you got to approve the theory
4. forgot to ask , just to be on the safe side your device is not in boot loop process, stuck on samsung splash screen or something like that, right?
okay, thanks!
1. I cannot access it trough USB to mobile way, but from SD card adapter, yeah I can (it is just the weird feeling, when you always have to put out your sd and do it that way, i would like to sort this out)
2. http://s1.postimg.org/nkta50u3x/Untitleddas.png I suppose the unknown device is my phone.
3. Just a question, my phone is not connected, i cannot access it and this doesn't help
4. Nope, it is working, i can access everything, just this connecting problem i have. anything else is running smoothly.
Let's say any of this will work, do you think flashing a stock rom will help? I am not sure, if this is problem of rom or not, so...
And maybe i wasn't clear (my bad if not) but when i plug the cable in my device and pc, pc will make this sound of new device found, but it wont show me anything, so my phone. It will charge, but it wont connect, it is behaving like it is on a charger and not connected to the phone.
@LiQuDiAk, Hasty actions are done in a hurry, sometimes without the necessary care or thought. Now let's not leap to any conclusion about your Android custom Rom and flashing back to stock. lets focus on your first most obvious problems,which is driver related.
You didn't declare your flavor of windows: i.e: Windows x86 based-PC;professional 7
Not so sure of your OS Name/Version and System Type, search "system information" in your search box.
Your task manger depicted ACPI x64 ( 64-bit system, no wonder previous 32-bit compatible didn't work out for you ).
Symptoms observed so far:
1. USB cable only charges ( remember your USB cable data line might be the culprit. Just in case of only charging,checking with another set recommended. Your USB port might be problem, some dirt or faulty data line, checking with another USP port doesn't heart though.
2. Windows recognizes something more (like in your case, struggling to find proper corresponding driver), but cannot see it as a Samsung android device (cannot allocate the installed USB drivers to the device).
-If you got Kies (Samsung proprietary software) installed on your PC, delete it with a descent uninstaller program such as CCleaner free version .Kies might cause driver conflict , use it as only last resort , if all drivers failed to communicate with s5830i device.
-Also Uninstall your previous given driver same way, now restart , back to system and grab set of universal Samsung Drivers from attachment .
3.Can't see your "USB connected" in Android notification bar, so you cant click on it and mount your storage data part while you are connected to your PC.
-Normally, when you plug in your Android device, Windows will recognize it as an MTP (Media Transfer Protocol) device and quietly mount it.
However, if you’ve ever attempted to unlock your device such as to install a new ROM or root it, then such miss behaviors might be expected occasionally .
Before i go for more troubleshooting , please provide a full screenshot from your "About Phone" page in your settings . I am quite curious about this phoenix Rom you have mentioned though . I am quite familiar with at least dozen of discontinued/ported projects, but never heard of such ported Rom from other models into s5830i .
Couple of solutions :
Navigate to your settings,Storage and touch the upper-right corner for the “USB computer connection” options, if you have this part available.
make sure “Media device (MTP)” is selected. ( if you have USB Utilities section or whatever added section in your custom settings go there . Selecting that will do the trick. If it does not, then you likely have a driver problem.
Open your device manager, Right click on your unrecognized device in question,choose update driver software, choose Browse my computer,find it through given x64 drivers in your package ,Restart. ( After a successful installation, restart your PC, you must have something like the picture in attachment ) .
Problem was not resolved, Uncheck your debugging option,power off your phone. Now hold Volume(+) + Home + Power for a couple of seconds simultaneously to get to your Samsung Recovery or your Clockwork Recovery, choose Reboot( might be some process/service in your background, which interfere with your Auto USB connected feature of your device. See if the problem is being resolved .
Problems have been persisting, we might need to format your SD card, but before that, insert it into your card reader, in your file explorer window choose Tools>Folder options>select view tab> tick your select hidden file.folders. Now copy all of your SD card's contents into some folder, safe inside your PC.
We can format your card through your clockwork mod recovery console, or some partition tools such as free mini partition wizard,,
problem still persist? let me know
Hey
After some rest with this, my mobile got it solved (dunno why, just once tried to do it and it works.)
So, thank you very much with your answers!!!!
And about that screenshots, I will PM you
But, really, thanks a lot, mate!!!!
I'm having error on Win10 when I connect my Mipad4 but it works well using the cable to charge. I've also tried a few cables. Is the port faulty?
Try another port.
Check connection settings in Developer options.
You need to authorize the connection first on the Adroid; a popup window will appear if connected*.
Go to Disk Management>scan drives, connect from here.
No joy? Check Event Viewer for error messages.
Try rolling back the driver in Hardware management, or updating it. No driver means no joy! Reboot, always reboot with Windows... it ain't no Android
*this is how a Samsung Android behaves... hopefully this will help; cross platforming.
Play with it...
Hello, I'm facing this problem from many years in my phone, i can't plug in my mate 10 to any pc, it always says usb not recognized,
all drivers installed correcly with hisuite , my cable usb is new,
i changed today the USB charging port of the phone at Huawei care service, and i reset factory the phone , still same problem.
I'm still having the same stock rom on the device,
is the "usb not recognized" problem can be a software problem in the phone? thank you for your experience.

I'll try to help you but I'm not an expert, and yet I've had EVERY problem you seem to be speaking about.
a. I have had broken USB ports
b. I have had broken USB cables
c. I have had the USB drivers not install on Windows
etc.
Given I've had some of the same problems, I feel for you, so my first advice is to simply give up on USB for everything that you can.
Specifically, if you can turn on USB debugging and Wireless debugging in the Developer options, you can operate the phone over Wi-Fi using the Windows monitor, keyboard and mouse as shown in my screenshots below.
You don't need anything installed on Android to use these FOSS solutions on Windows to operate the entire phone over Wi-Fi as of Android 12 (which eliminated the need for an initial USB connection to establish the Wi-Fi connection).
In summary, I have had similar problems with USB where I've given up on USB and switched to operating Android over Wi-Fi and even mounting the entire Android file system as a Windows drive letter over Wi-Fi using free software.
a. adb
b. scrcpy
c. vysor
d. webdav
Use Windows Event Viewer to check for error messages on the PC.
If the problem is the PC it will likely show up there and give you more troubleshooting clues.
