UNIVERSAL in Boatloader mode not recognized by PC-USB

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

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.

[Q] WinMo wont connect via USB since new Froyo installed.

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.

That did not work...
How do I get my Win7 laptop to see the phone with Android on it?

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.

[Q] Note 2 not recognized by PC

Hi friends
I am facing problem with my Galaxy Note 2.
Earlier when I first connected to PC it asked me whether I would like to use only as charging or for Media Transfer.
I choose Charging Only.
Now after automatic upgrading ( not rooted) I am not able to connect to my PC.
It only charges but I cannot use for Media Transfer, Even I cannot find where this option is.
After a lot of surfing in internet I changed pc, cable ( original), enabled USB debugging mode from developer options, enabled code *#7284#, *#0808# etc....
but the end result is same, All PC just says USB not recognized.
I have files in it which needs to be transferred so I don't want to be rooted or hard formatted.
Hope anyone can help.

Same...
Same problem....

Dear All
Sorry for bothering...
it was hardware problem, faulty IC.
I reapired it
