USB Device Not Recognised on Bootloader

I have a problem. My Exec is stuck on the bootloader screen. All I see is Serial at the top, and v1.00 at the bottom.
When I connect my exec via USB, the screen continues to say Serial (rather than switching to USB) and the PC I connect to 'installs' the device as 'unknown device' in device manager.
I've seen mention of the problem elsewhere on the site, but the only solution I can find seems to be to keep trying, and eventually it's recognised. So far, after three days of trying, it has not been recognised.
I am aware of Buzz tool to get the device out of bootloader mode, but that required a connection to be established, which at the moment, I can't do.
Has anyone got any experience of this, or any ideas as to what's causing this, or how this can be fixed? I have tried uninstalling the 'unknown device' from device manger, restarting the PC (and hard reset of the Exec) then reconnecting, but the same thing happens every time.
Any ideas would be appreciated, as I'm currently staring at a rather expensive paper weight.

Try this it shld work

This is based on my experience with two UNis..one Exec and other JASJAR..both had same problem...this is how I solved :
-Put yr device in bootloader Mode
-Disable USB in Active Sync
-Now connect woth USB cable and open mtty utility
-Select the "WESUSB... " port
-You shall see a blank white screen..press Enter to get "USB>"
-Then type ( as BUzz has informed) set 14 0
(here I wud like to inform that after doing the above I did not get success so I typed set 14 10,then set 14 9 for two three times)
-Then I ran the ROM Upgrade directly(After enbabling the USB)
-I then followed the procedure as informed on the COngratulations Screen that is hold the two "-" buttons and soft reset and then pressed 0
-I got them back to normal..
I hope this helps to all my friends...Pls feel free..pls do not trouble our Buzz..he might be busy in inventing something more to our devices

Try it with a different USB cable or in a different USB port (don't go through a hub and if you've been using a laptop then try it on a desktop PC since some laptops have hubs built into them). If that doesn't work then you're out of luck as your Universal isn't detecting that you've connected to your PC and its time to send it in for repair.

Thanks Niketkumar - unfortunately it's the step before your suggestion kicks in thats the problem - the device won't connect to the PC, so when using mtty WESUSB..... isn't an option, only COM1 and COM2.
Shuflie, I've tried with three separate USB cables on a laptop and desktop (neither through a hub, and the same device has worked fine on both laptop and desktop before).
I fear a trip to the doctors is in order ...
Very frustrating because the PC sees a device, but installs it as unknown device. Anyone know if theres a Windows CE device driver that I could try and install as an overide (i.e. in device manager on the PC go to update driver and browse to a WinCE.inf or equivalent?)
Failing this, has anyone got any clue what needs to be fixed? Or how much it might cost?

i am stuck on the same problem and wondering the forum for almost 3 days now with no luck.... please help my device is in boot loader mood but not turning the serial to USB ......... please HELP.......

Please follow the steps:
1. Plug in ur usb cable in bootloader mode while it is showing 'serial' and version 'x.xx'.
2. Soft reset by pressing Backlight+power+reset pin WHILE KEEPING THE USB CABLE CONNECTED
3. your phone will now reboot into 'usb' mode. Don't remove the usb cable yet.
4. Remove the Memory card while keeping the usb cable still connected and VOILA,your pc starts recognising your phone as Microsoft usb sync.
5. Do whatever you want to do now (upgrade)
Hope it solves the problem now.
Press thanks if it does.

Something else to try
Having had a few issues with my G3 Uni, I've been through my fare share of Uni bootloader issues. When I find that I can't get the 'serial' to go to 'USB', I normally find it's because I haven't taken the memory card or the SIM card out (usually the memory card).
Make sure your memory card is out, then try to enter the bootloader and see if this cures it. If it does, then use mtty and the command 'set 14 0'
This tells it to reboot on reset. if you were to use 'set 14 1' it would go back to the bootloader on reset.

[Q] Problems with SEUS

Hi - more questions, but this time its a problem I'm having. Before flashing the latest O2 UK firmware I want to decrypt my current Orange France 2.3.2 firmware in case I need to go back to it. However, I'm assuming that I need to connect with SEUS once (and possibly update whatever they have) so I can then find the current firmware files in the SEUS folders on my PC.
Anyway, the long and short of it is that when I am told to hold the back button while connecting the phone, NOTHING HAPPENS. I've tried loads of times, tried reinstalling SEUS, nothing. Some drivers started to install, and all seems OK there - no yellow triangles in device manager. Also installed PC Companion (automatically offered when I connected the phone with it turned on). It installed drivers then too. All fine. I tried using a different USB cable too - no luck.
Any clues ?? Searched Sony Ericsson site and it is bare of useful info. Did a search here too but no luck either.
Thanks in advance.

and you followed the instruction as they say:
1. switch off the phone
2. wait for 30 seconds or so (pref. remove the battery and insert it)
3. hold the back button
4. insert usb..
it should detect the phone no matter what. i hope there is some juice in battery...

I've heard that SEUS and PCC now are able to detect rooted phones and don't let you reinstall stock software. It needs the stock build.prop

Thanks for the replies. I have been pulling my hair out on this. I realised that it is to do with my SECM USB Flash drivers being faulty or something.
I tried to use PC Companion and it got to the same bit where SEUS crashes - right when it wants to get in to flash mode on the phone. It hangs the computer up.
I have googled like crazy and have seen reports of others PCs hanging at the same place. BUT, I can't find a way to repair or reinstall the USB Flash drivers - I've reinstalled SEUS and PC Companion plenty of times, with my anti-virus off. And tried to get in to flash mode with the anti virus off.
Problem I think I had is that a lightning storm stopped my first installation of PC Companion - I think it may have screwed something.
Any ideas how to fix the usb flash drivers ???

Have you tried de-installing SEUS and PCC, then in device manager search for and remove the USB Drivers for SEMC.. then reboot.. then re-install SEUS..
??

Thanks - tried that but no luck unfortunately. Couldn't even see anything in Device Manager to do with SEMC, SEUS or Sony Ericsson - was looking under USB Controllers. When I did a full search I did find plenty of traces of the drivers GGSEMC (Gordons Gate Flash USB drivers) in both system32 folder and in the Sony Ericsson folder left over after uninstalling SEUS. Didn't want to just delete the ones in system folders.

you could try doing the "update driver" operation - my driver was called Sony Ericsson seechri (or something like that!).... see if you can repair..

Perhaps you could try on ur friends pc. Just to confirm that seus is the problem.

SOLVED (sort of)
Thanks for the advice.
OK - I tried on another machine (why didn't I do that 6 hours earlier ). Works fine on Win7 64 bit. Maybe the drivers didn't get installed properly on Win XP ?? Going to have a go rolling back to an earlier restore point on the XP machine to see if I can get it working.
Anyway, SOLVED. Thanks

[Q] PC won't detect Arc

Greetings!
Past couple of weeks when trying to connect my Arc to the PC it will not pick it up. It charges OK with the green light showing on the side but absolutely no indication from PC or laptop that a phone is connected.. I have 3 different cables and another laptop - having tried all the cables on both machines - still no joy.
No notification in the pull down - nada!
Reinstalled Win7 and factory reset phone half a dozen times - still nothing!
Running Win7 64bit but have never had issues with OS previously up until a few weeks ago!
Service provider was as useful as an ashtray on a motorbike!
Anyone know a solution?
Thanks

install PC companion and SE Update Service, enable usb debugg mode on phone, look at your ubs connection settings on phone too

Thanks for the reply TheHaso. Should have mentioned I have tried with Companion installed and not installed, updater installed and not installed. With debug on & off, MTP on & off, MSC on & off, storage mounted/unmounted.
Really strange to be honest!

check your 'Device Manager' on your desktop,, it will show you if any hardware connected and not working propely.
right click and try update driver if show caution on portable devices.

Also tried this for a solution buddy.. Thought it was a USB driver had slipped off or something.
Truly baffled! If it's charging fine then why would pc companion not detect it :-S

I'm sure you must have already done that but may be try updating with a different driver and see if it could solve problem. I know because it also happened to me.

Greetings, which other driver would you be referring to? I have literally tried everything but still no detection from PC in MTP or MSC.

Uninstall the driver from device manager, then restart the pc and connect to another usb port

This will work...
I have almost the same problem on my ARC.
Download MyPhoneExplorer on your PC and install it.
Download MyPhoneExplorer Client from the market and install it on your phone.
Turn on USB debugging and connect your phone with your PC.
This works on my arc and i guess it will work on you phone as well..

Xperia Z1 Compact - Data recovery

Hi guys and ladies. I apologize in advance for my English. I'm new here and I need some help
My phone Sony Xperia Z1C fell in sea. It should be waterproof but since it was in repair shop it isn't.
It's not completely dead, when it's plug on charger it shows that it's being charged and when I try it connect to my PC/laptop Windows beeps that it's connected and in few seconds that is disconnected. I cannot see anything on phone because screen is dead.
I want to recover whatsapp messages, pics and contacts, the rest is irrelevant
PLS help

I guess you could try adb, if you have it on your computer. Have you used adb terminal commands before?

Well, I'm not sure if it will work with the phone very damaged, but I don't know what else to try. I'm pretty sure the phone has to be rooted, and have 'usb debugging' checked. If so...
Start with installing this - https://www.google.com/url?q=http:/...SWWAGo&usg=AFQjCNFMZS_C72TYnLboFWunYSIKwb5Vhg - then open a command prompt on your computer in the directory where the adb files are installed. First type 'adb' and hit enter, to confirm that it is installed and you're in the right directory. You should get a long list of command options. If so, plug in the phone with it turned on, and type 'adb devices', and you should get a number showing that there is a device connected. Then you can use adb shell to pull files.
You'll need drives installed for your phone. If you've used Flashtool or PC Companion, you already have them. If not, there's a few ways to do it...

Hi all, I have in my possession a Sony Xperia Z5 Premium (E6853) International version, recently trip and put it in a somewhat old PC running Windows XP, the phone was working perfectly until now, after having logged started to give problems , I explain in great detail:
When i connecting for the first time, the phone was powered off and would not turn on, then when connected to the PC, lit perfectly, but to my surprise, when connected to other computers, just start to charge, the phone did not recognize computers, i change the cable, nothing, restarting the phone, not even charge, nothing happend, when it goes out, and relit, the phone was connected perfectly fine, and loaded, this worked only once since then repeated the same process, and it did not work, now only charge when the battery reaches to 0%, and the phone does not turn off when I press the power off, only restarts, comes to the screen where advertised sony, and again restart,, the phone is running android 5.1.1 lollipop, and I tried to hard reset 2 times, download the full phone battery and give it charge, dont know what else to do, I need help if someone has happened something like this, greetings and thanks.
Sorry for my english...

My recommendation: Warranty repair/ replacement

Have you got Sony PC Companion installed?
What usb driver is installed? Did the PCC install the MTP driver on computers you connected to?
Check device manager on you PC when you connect your phone to it and see if it recognises your phone correctly otherwise try uninstalling the usb driver and connecting your phone once the Sony PC companion has installed the necessary drivers.
Also try factory resetting if you can see if that helps

I have windows 10 installed on my pc with all the drivers and, yes, has Sony PC Companion installed too, normally before the problem, i was conect my phone and it made a sound but now do nothing,, i try the factory reset twice and the problem persist, maybe the phone has drivers too and was corrupted somehow, all that is the PC problem, the other one is the charger problem....
i conect the phone to de charger and nothing happend same like PC, no charging at all, the only way to charge the phone is it gets out of power completely, dead, thats the only way to charge it but the battery is suffering with that way
