I tried to upgrade my rom but the process crashed. The utility mtty doesn't work because when I connect the universal, boatloader mode by the cable, to the pc, it says "USB not recognized" (sometimes when I connect the computer is frozen till I disconnect the cable of the universal)
Please, I tried to have some solutions in the forum but all the posts indicates is needed previously the usb connection.
Do you know if should be possible to run the flash of the rom in other way, for example using a serial cable connected into the miniusb of the universal, because the boatloader screen says "Serie, v.1.01"
I apprecite what you can say please, I'm really in a hole.
Try this...
Try taking out the battery for a few minutes (10-30mins) and reboot your PC then repeat upgrade process. Hope that helps. Good luck!!!
I have the same problem on my PC at work, it's caused by a poor USB chipset in the PC, or trying to connect through a USB hub.
The only thing I found that worked was to try a different PC, then it was fine...

In my case it still happening in other computers. Conclussion: some piece of the software in the universal has been lost. The screen shows "Serial" that means on some way that is opened to comunication but not USB.
My questions are:
- should be possible to put some starting software in SD and do the universal boot on it.
- do you know how to connect to the computer COM! port from the usb miniport of the Universal.
I appreciate, I was not planning to replace now the Universal...

Now works.... I still thinking windows is so stupid software made for distroy our mind ....
Solved after install drivers for a converter usb -rs232 ( I was looking for the way to connect from rs232 the universal)
I'm happy again and I promise don't try to change rom again (at least for a while)
If some person is interested in what brand of software/hardware I installed, send me a mail...
Thanks hearing me ...

i have the same problem with my friend's uni
does it mean that you don't have to own any adapter, just have to install drivers for USB to RS232 adapter
if yes, where to find it?
thanx
respectfully

I want to say that is running after doing some things and obviously some of it solved my problems. I made:
- unistall last version of activesync and go back to version 4.0
- delete all the applications using ports usb.
due the connection still not running (windows message: device not recognized) and because in the screen of universal I saw: "COMM1" I tried to connect from computer port rs232. By that I purchased some special cable, name: hama brand, rs232 serial, 9 pin - usb.
As you can imagine all the steps I followed were followed by the typical restart of windows. In this sense is important to say that the universal, after connect, need to do a soft reset each time (again windows....)
Other comment is that I unmark the option to connect by usb in activesync and mark the connection by com1.
and after all was done, connecting by usb the unniversal, kill wcescomm, windows said "NEw usb device, sync device". I started mtty and now appears the USB option, great! same time the screen in universal changed from comm1 to usb, more great....
and that's all.
does it mean you solve your problem using special USB 2 RS232 connector?
ZeD
PS: it was my first idea , but i still believe i can solve the problem using USB port

I think my english wording was not fine. I mean I solved my problem after install the sofware -drivers- of the rs232 connector, but connecting to the universal by usb as on standard way I was syncronizing previous the crack with activesync.
OK, where to get this driver?
thanx
?????????? NOTHING ?????????????

I have had the same problem several times now (search the forum for the thread).
I tried three different PC's/laptops and three different USB cables all with the same error as yourself.
Eventually I got a connection but the laborious process of trying - failing, restarting windows and soft resetting the phone, trying - failing........... until it finally worked. I did nothing differently the time that it worked but the strange thing is that it has worked every time since! Maybe the USB driver the phone has a bug in it that causes it to get 'stuck' in a mode where it will no longer correctly operate but once you have managed to 'kick' it into action it seems toi then carry on working.
It was also a ROM upgrade that caused my USB phone driver to stop functioning. Maybe the fact that the phone has a slightly diffferent software configuration after the upgrade but exactly the same hardware fingerprint causes the driver to fail.
Every time that I have had this problem it is after an upgrade but once I have gotten it to work once with the new ROM, it always continues to function - until the next upgrade.

If you're stuck in bootloader mode only, visit www.buzzdev.netand look for ExitBootloader utility written by the great Buzz. Just follow his instructions or scroll thru' Universal's forum here and there for problems relating to "stuck in bootloader"
hope this helps
no device is not recognized by PC so any trying to use exitbl is not available, anyway this option was one of the first what i have tried
thanx anyway
ZeD
i had the same problem with the QTEK of my principal after I upgraded his ROMs.
(after the hard reset, the pocket remained in bootloader mode).
you can solve this problem in a very simple way:
you have to launch the bootloader installation (BL1.01_RUU_UNI_V.1.2.EXE) from the PC (still connected with the PPC through USB) while the PPC is in bootloader mode (on your display you see "USB > Serial 1.01" or something like that).
then you do a SOFT reset and the pocket boot normally.
very simple.
i hope to be helpful to someone.

I had some problem. After uninstall all usb applications in the pc and install the software for cable usb -rs 232, doing some softreset in the pda connected, it turned the screen message "Com" by "Usb"
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
hdubli said:
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.

the first point...
A lot easier than to root this device
Hi, I have reflashed my ROM I dont know how many times. Yesterday I tried to connect via activesync on a new ROM and it wouldnt connect. These are some of the things that happened:
Device orange charging light flashes a few times then goes off [never seen THAT before]
Activesyc menu comes up on device but activesync doesnt connect
Get 'this device can perform faster' message on desktop
Sometimes get USB devce not recognized on desktop
SOmetimes device orange charging light it stays on if I plug direct into PC but still doesnt activesync
I have tried to connect as DISK DRIVE but I dont see the device on my PC.
Have tried different ROMS, 6.5, 6.51, sense 2.1 and 2.5 but all have same issue. Have also tried connecting to other computers. same issue.
Have played around with USB to PC menu options (enable / diable faster data sync etc) but doesnt make a difference.
Anyone had this problems? Thoughts?
Have you tried diselecting "ask me 1st about usb connection type when I connect the device to the pc" under USB to PC settings
It worked for me
This is the exact problem I am facing!
I tried everything - as diskdrive, activesync (with/without speedup), etc.
On many ROMs, even the original one (WM6.1)
Can't connect - every PC gives an 'unknown device' and on some ROMs I cannot charge via USB, only via mains...
I also tried without the question on connection.
Just some thoughts:
Do you have corruptions on screen sometimes? (Some graphical glitches)
Any .CAB files you cannot install?
Did you try to reflash the same ROM more than once?
tried to connect without card in the device and in flight mode? (Uses less power)
With me it started after a ROM flash from Miri... (I don't blame him!!)
The Hard SPL did not give me any problem, the radio was not flashed, just the OS. But reverting did not help.
I certainly hope you will find a solution, since I have the exact same problem!!
Do you stil know what ROM you flashed when this problem occured?
I reverted to original ROM 6.1 AND 6.5 which included everything - boot, radio, os, stardup image. But it did not change!
I figured it out after trying everything i could: i think its a hardware problem. I have dropped my devicetoo many times, or plugged it in too many times. Who knows.

And how did you figured it out? Did you return the device to the shop?
I have this exact same issue except I am on AthineOS... I thought it was my PC until I read these posts. No OS updates or any other machine updates were performed except on my device. Any clues as to a fix?
Somehow I don't think this is just hardware.
I did drop my device once, but that was even before first flash. After that it still worked.
So, some weeks later I HSPLed without any problem. After that the device still worked.
Then, after investigating which ROM to use I flashed the ROM a few days later.
Right after the first flash it all still worked. So, had to flash another and from that moment on the device cannot be reckognised by any PC.
I still think it has something to do with the flashing. I think the device does not give correct feedback when it receives some commands from PC (eg. the command to reply the device type/number)
Does anyone know a program which can check the USB port for the HTC Touch Pro 2? Just to test wheather the connector pins are ok?
download activesync 4.5 and run the setup. it will perform a repair. that usually solves the problem. if not, try a different usb cable and try plugging into different ports on your pc.

These are the first things done. And this was already written in here.
It happens with many PCs, including some on which the device never connected to.
Also tried different cables, ports, etc.
Also disabled the fast transfer etc. etc.
Even tried several other ROMs, inclusding original Dutch 6.1 and Dutch 6.5
I'm having the same issue. I can connect via bluetooth, but not usb. And I'm stuck with 6.1. I was tole my phone was brand new, but now I'm starting to think otherwise.

Some questions, to verify this is due to flashing or is a fault in the design of the device...
- Where did you get the device?
- Have you flashed the device?
- Did you accidentally drop the device?
hi just to say had a completely orignal o2 xda orbit 1 flashed with new rom everything worked perfect before now active sync plays up i can sometimes connect but get usb device not reconigsed then click cross then pull out usb then reinsert then active sync connects works fully functional then after 5 min it disconects this is driving me mad as use active sync for a fast internet connection on my pda as my wifi is crap
I was trying to put the hum/hiss sound fix on my sd card and I cannot get my pc to connect via USB...
My wife has a TP2 and it connects fine...
I have tried with/without the sd card in, rebooted the pc and phone, rebooted the phone while connected to the pc.... nothing...
wtf...
anyone else with this problem?
PS... NRGZ28 had posted a very basic rom for booting to android back in Feb and it is now gone from hotfile. Anyone know of a quick boot into android?
- Try a different computer
- Try a hard reset
That are the first thing you should do.
Tried hard reset...
Dif PC is not an option at the moment... I have rebooted...
Just flashed the ROM (NRGZ newest, thank goodness I had it on my SD card) and I still cant get it to sync...
I have attached the USB error I am getting... (Win7, new install)
The phone is not asking if I want to active sync or use as storage???? wtf...

Reboot your PC? lol bet your tried that already...
Try this:
settings > connections > usb to pc > and disable Faster Data Sync then try. This way uses the generic usb drivers and maybe it will connect.

dont think thats working yet
Ya I don't think that works yet, it's tied to Android software drivers and the use of the USB port, since there is no drivers to control the port only to charge battery. Windows thinks there is something there, but the phones USB can't communicate back....I think this is the issue or at lease after playing around with it on my phone anyway
Not that it's a huge amount of help but might troubleshoot down to the hardware level...if you go into bootloader mode on the phone and connect to USB does it connect?
I don't think you should go that deep and dirty. My touch pro 2 works only with only 1 (non-HTC) cable of the 10 i have at home, all are the "standard" mini-USB but only one works flawlessly for communicating/flashing/syncing, the other cables either do the same error - device not recognized - or windows says that the device could communicate faster - and only copies files slowly.
All in all: you should simply check with another USB cable or if you have the factory HTC cable try it with that. I noticed that the cable i am using other than the HTC one is a very good quality thick (low-resistance and double-shielded) USB cable and it never failed on me.
One other thing you should definitely watch for: plug the USB cable into the motherboard USB port directly (on the back of the PC where you plug the keyboard, mouse etc.), sometimes PC cases with front panel USB outputs simply die, or are wrongly attached to the motherboard USB header and it can cause the aforementioned problems too, not to mention if it is wrongly attached it could harm your phone too.
Hello,
All of a sudden my LG G4, Model 815 can't be recognised by computers anymore. Tried different PC's, with different OS, also have tried different cables. I have been using official cable that I found in original package and everything was working good, but now the phone only shows charging and PC's are showing popups that usb device is not recognised.
I was doing a little reasearch and already tried some simpliest things - reinstalling drivers, tried different cables, different PC's. For example my cable works fine with HTC M9, but doesn't do the thing for me anymore. And vice versa HTC cable works for HTC and does not for my LG. Also I found that you must simply select "charging" in top of your left corner and just select MTP. The problems is, that is not shown in my phone anymore. I'm thinking of trying to do factory reset, but before that maybe some of you have some thoughts? Could it be my phone hardware problem? Before a couple of days ago when everyting was working fine, I did not do anyting unusual, also that phone was never rooted, so I can't believe that it is somehow broken. I have it for nearly three months I think.
And yes, I understand that I can simply transfer my files through, for example AirAndroid of similar apps, but I cannot stand that error sounds playing on my laptop when I connect my phone through the cable to charge it.
Now it is running Android OS 6.0 (marshmallow)
LG G4 MTP Transfer Broken
Hello XDA,
I am having the exact same issue. MTP worked fine and then one day stopped. I believe it happened when I tried to transfer photos from phone to computer via USB and File Explorer. The transfer started, then after about 3 images transferred I received an error, "file transfer the system cannot find the file specified", after that the USB logo disappears, it will disappear from Device Manager, it will not even charge via USB. A phone reboot will fix the USB charging, but the option to switch to MTP is gone. I can't which it in in Developer Options either.
I've also tried all the same things LocaSnai suggested. Such as, different cords (3 of them), windows drivers, LG Air Drive, LG PC Suite, and LG Mobile Support Tool, Verizon Wireless Software Upgrade Assistant, of which none will update or repair the phone. I've also restarted Media Storage service (force stop and reboot). My Nexus 7 tablet connects perfect every time using the same 3 cables. The wife's i phone 6 also connects without issue.
I have performed a factory reset and MTP worked UNTIL I restored the LG backup. Then it went back to the same issue. Factory reset was a LG Support idea. They said that if it happened after the factory reset and back up restore, it could be a virus or issue with an app. How would we go about detecting what is wrong?
While working on this message I tired a few new things. I am able to get MTP to show up (not work as it used to) by plugging the phone into power, and then unplugging and plugging into USB. Each time, MTP will recognize (I tried all the software above when MTP shows up, none recognize the phone.) If I unplug USB and plug back into USB, MTP will not show up, only charge will. Have to plug into power then back to USB (I am using two cables, one in the brick and one in USB. Nexus 7 will work as expected with the same two cables). Some times I see the Yellow Triangle over the LG UBS entry, but following this tutorial doesn't work: www.verizonwireless.com/support/knowledge-base-161810/ Uninstalling the driver and letting it reinstall.
My phone is as original as the day I bought it. ie not rooted or tampered with. Android is up-to-date.
Thank you in advance to the kind folks who offer assistance!

Hello XDA,
I am having the exact same issue. MTP worked fine and then one day stopped. I believe it happened when I tried to transfer photos from phone to computer via USB and File Explorer. The transfer started, then after about 3 images transferred I received an error, "file transfer the system cannot find the file specified", after that the USB logo disappears, it will disappear from Device Manager, it will not even charge via USB. A phone reboot will fix the USB charging, but the option to switch to MTP is gone. I can't which it in in Developer Options either.
I've also tried all the same things LocaSnai suggested.

I've also restarted Media Storage service (force stop and reboot). My Nexus 7 tablet connects perfect every time using the same 3 cables. The wife's i phone 6 also connects without issue.

I had the same problem (at the same time I had problems with my sim and my message light was showing a dim green..), tried everything, drivers, cables, at the end a different pc and then I rebooted my phone while It was connected to the 2nd pc, after this, every problem was gone and I good see my phone again in windows. Now after a few reboots with and without the connection to a pc, the phone seems to be working as usual again...
(and My phone is also as original as the day I bought it. ie not rooted or tampered with. Android is up-to-date.)
Doorwerth, thank you for the suggestion. Tried that a few minutes ago and still have an issue.
I'm considering this next: LG G4: How to Boot into Download Mode. I think it's a bit extreme.
