Stuck in bootloader problem - JASJAR, XDA Exec, MDA Pro Software Upgrading

I have a HTC Universal (Qtek 9000) device.
In an attempt to do an upgrade to bootloader v1.01, I kept getting a connection error. Apparently even while I got this error, the upgrade still managed to get my device stuck in bootloader screen
Luckily, my pc still recognizes my device when I connect it on USB. So I'm following the steps described on Wiki to solve the problem.
I disabled USB connection in WMDC, removed Sim & SD cards from the Universal, and connected it without any USB hub, or even any other USB devices connected at all. Windows installs drivers succesfully, but right after it the MS USB Sync icon disappears.
Mtty doesn't list the USB port in the ports list, and UNI_ExitBootloader gives an error "Cannot open USB port".
I tried all ports of my pc, and tried another cable too. The device indicates "USB" in the bootlader screen so it recognizes being connected.
Does anyone have an idea what could be the problem here?
Or better... what I can try to fix it

Try to reflash on windows XP, not Vista
Hope it helps,

That did help indeed, thanks!
Don't know what Vista does to my USB ports (and probably don't wanna know), but a XP VM did the trick already
My Universal is fully operational again.

Can't get USB connection to upgrade again

Hi all,
I have this particularily annoying problem that effects my ability to upgrade the rom files on my universal sometimes.
When I put my device into boot mode I don't see USB v1 or even Serial v1, what I get is Serial v2.01
Sometimes when I then connect the USB cable into the universal this changes to USB v2.01 and windows recognises the device and I can perform the rom upgrade. Most of the time however, it stays at Serial v2.01 and windows complains about 'USB Device Not Unrecognized'.
I have tried 2 different USB cables with the same outcome.
Normally after trying s few dozen times I eventually get windows to recognise the universal and perform the upgrade but I have been stuck like this for 3 days now and am getting close to my breaking point which will could shortly result in a broken universal.
Please help.
i cant quite remember the ins and outs but i have faced this problem as well
firstly ensure your connected directly to the computer and not via a hub,
try to do the upgrade if/when you get the message remove the device from the cable and do a soft reset
try the upgrade again and it should be successful this time .
i have had lots of trouble myself with this and i have found a soft reset always gets me there in the end.
goodluck !
I have just retried the upgrade and the display keep changing from USB to Serial about every 10 seconds.
I also noticed that the mouse kept freezing on the screen for a few seconds whilst this was happening. I tried using my other USB cable and the same thing was happening.
Does anyone else have v2.01 displayed on their screen like me?
Update: I stupidly ran Ivan's AKU3.2 upgrade utility whilst the universal was activesynced to my desktop (not in bootloader mode) and now this has executed the EnterBL.exe program which traps you in the booloader unless you upgrade a rom (or use mtty to issue the correct command to escape).
Unfortunately I can't excape via either of these methods as I still can't obtain a USB connection.
I have even tried a different PC but am still stuck.
Maybe both of my USB cables are knackered, so I will obtain another one and try that. If that fails it looks like Orange will be recieving a little parcel from me...
I have now also tried a 3rd USB cable with the same result.
I have a similar problem, I'm stuck in bootloader mode.
I have version 0.60 and if I put a USB in it keeps on saying serial and my computer says he doesn't recognise the device.
I've tried it on 2 different computers as on my new one apparantely all my usb ports are part of a hub. (they come up as all, inluding the ones in my moniter, being part of an usb root hub) But no succes on my other computer either.
I'm thinking that my only option is to do it via a memory card? Can anyone tell me how I'd go about that as I have no clue :shock:
Thanks!

Success!
I have been plugging in and unplugging my phone all day (with it still stuck in boot mode) and eventually it was recongised by my PC - I then upgraded the radio stack & ce rom and I am up and running again (I know that I could have used buzz's utility but I wanted to upgrade anyway).
The only thing that I did slightly differently this time was that I actually removed the battery from the univeral for a while and then plugged it back in before trying the USB connection. I did try this once of twice before without success though so can't really draw any conclusions apart from I don't know what is going on.

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?

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?

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"

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
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.

Computer cant recognize my Diamon

Dear Sirs;
Maybe this part of forum not be the proper place for my question but I don't know the poeple more expert than XDA masters.
Since last monday, computer cant recognize my Diamond when I connect it by USB cable and "USB device not recognized" appears. I will be really appreciated if you kindly help me.
Best Regards
Dariush Chegini
Try reinstalling Active Sync/Windows Mobile Device Center.
First remove Active Sync/ WMDC, restart PC and than install Active Sync/ WMDC.
Thanks for your kind attention. I reinstalled Activesync...no change, computer can't recognize the Diamond. My Diamond charges with both charger and computer, USB headphone works but PC can't recognize it....
I'm so confused and will be really appreciated if XDA masters help me.
Best Regards
XP or Vista or Windows 7 or which OS?
I've tried by both WIN XP and Vista.
could be a few possibilities for XP atleast...
activesync - file->connection settings->allow usb connections checked
faulty cable, try another one
faulty port on computer, try another one
driver issue - a difficult one...
i had this on my xp, found out there's something wrong with the cable - phone charging fine via computer USB, but XP says it doesn't recognize the device so doesn't connect to activesync....
good luck
Try on your Diamond -
Start>Settings>USB to PC
Unchek "Enable faster data synchronization"
If none of the above solutions work, maybe a hard reset...
I tried another cables, all options in "USB to PC", Activesync options, hardreset, even install other ROM but PC still can't recognize the Diamond.
It seems to be a Hardware problem but Diamond can be charged by USB and USB headphone works properly... I'm so confused .
Thanks Millions

Try this in order...
1. Connect diamond to pc - it should at least charge as your say, but not detect Activsync
2. Goto Settings > Connections > USB to PC
3. Check Allow USB Connections > Uncheck allow fast data sync...
Does it connect?
if not and if you are using Vista
1. goto Windows Mobile device Center
2. check the attached image to see you have the same settings...
Does it connect?
if still not, then it could be driver issues, which I can suggest, once you reply to the above...
Thanx for your attentions. I've tried uncheking the said bottom but no change.
I used to connect the Diamond to the same notebook without any problem for more than 16 months, but the damn notebook stop recognizing my Diamond these days .
Thanks Millions
Dariush
may be usb port on your computer is malfunction. Did u try different usb port?
You need to open device manager in control panel to see how you diamond is listed.
Ever since i started with a new company 3 years ago they have some software that prevents activesync from connecting to any device I have from their computers using USB.
I went Bluetooth method and all is fine. I just use the USB for large, direct file transfer to internal storage.
If you get issues with activesync and usb and can take ages to resolve (if possible).
I guy's.
After a lot of search in this forum and a lot of other forum's, i came to this threat.
I had the same problem, my diamond didn't connect to my pc.
I had tried all the different suggestion, and nothing seemed to work. until i read the post of cloudedhopes, that suggested to change the usb cable. Because it was the only thing that i hadn't tried, i did change the cable, and it worked!
So i'm posting only to thank you guy's for all of the help, given not directly to me, but to all user!

[Q] USB connection fails on 3 different PCs

I wanted to root my phone and flash a costum rom... unfortunately my DHD (2.2.1) is T-Mobile branded, so i had to create a goldcard in order to downgrade from 1.75.111.2 to 1.32. When it came to temproot it manually with cmd i had to plug my DHD into my PC in load only mode, usb debugging activated.
I knew already that my DHD wont recognize my PC or the other way round (i somehow broke it when i deleted the htcsync drivers.exe from my sd card), but i thought maybe it would somehow work in usb debugging mode.
Well, it didnt(phone not found).
i then focused on repairing my usb connection, so i tried it on 2 other pcs (mine is w7, the other ones are xp and win7) but it all failed
(xp asked for drivers, which i installed directly from htc.com today(on all pcs(plus i removed and reinstalled them all properly))/win7 did nothing/mine said that it fails to connect and that i should use a usb 2.0 port(well all ports are usb 2.0, i also tried usb3.0))
evertime i plugged my DHD in i was asked which connection i want to use, none worked, i also restarted my phone several times (usb connected and without) when i type in #7284# (or *#7284# i tried both) it says: connection failure or invalid mmi code
Finally i resetted my phone and did it all again! But it wont work!
please help me!
Hi...It looks like a driver issue...
If your drivers are installed correctly, in your win-7 Device manager it will show DHD.
I would suggest to Re-install HTC Sync from HTC website - Run it again and give it a try
doesnt work either.... win7 says the device does not run properly, my phone does nothin unusual...
i wonder if htc could fix the issue... this would be my last option
however i believe in you guys at xda!
how did you reset your phone?
Did you install the android SDK? Does adb recognize your phone? (run "adb devices", if your device is listed, everything should be fine)
On my win7-machine, the HTC-Software gives me an error message (along the lines of "phone doesn't respond" or something like that) but adb works nonetheless.
thank you for your answer but im afraid it didnt work... i installed the usb driver pack on sdk but i couldnt find it under sdk/usb driver..., however i found some files -> android/android-sdk/extras/google/usbdriver/amd64 -> usbdrivercoinstall2.dll... i tried to install this driver in hardware manager, and i tried to install an adb.exe which i found in my downgrade folder as a driver. but win7 said no driver installation is necessary the "best" drivers are already installed (win7 aint gonna install anything)
also my dhd is found under unkown device, -this device is deactivated because it made errors- "Dieses Gerät wurde angehalten, weil es Fehler gemeldet hat. (Code 43)"
well i deinstalled it and searched for new hardware, he now says the drivers are installed properly please restart however i neither see my sd card nor my devices name (instead unkown device with this little yellow triangle)
btw. for reset i used my android reset (settings -> sdcard -> reset)
It is normal, the HTC Sync turns on the USB debug?
Have the same issue. My DHD can be connected to the PC no other way than charge mode, no matter is usb debugging turned on or off. Tried 2 PCs with W7 and 1 PC with Ubuntu 10.04. This trouble appeared several days ago. Wipe didn't help. Thinking of re-installing firmware, but it seems like hardware problem. An engineer in our service center said it might be motherboard malfunction.
Some ways of solving this problem are described here: http://goo.gl/2eMcP But none of those solutions helped me. If anyone can help, please advise.
UPD: re-installing the firmware had no success - connection with PC failed. 95% hardware problem, will take it to service center.
Guys I know it's a stupid advice, but I had same problems (suddenly my connection with pc didn't work anymore): did you try to change usb cable?

Click to expand...
Click to collapse
tried 3 cables and 3 PCs
i just found a solution for me : i tried a forth pc (win7) freshly installed htcsync + android sdk + !downloaded! (not properly installed) adb drivers (which i surprisingly did not need) well i plugged my DHD in and he installed all drivers, but never asked for an adb driver. instead he had problems installing 7 different bluetooth drivers for my DHD (???)^^
it just worked for me this way (also worked for debugging mode + load only mode (for radio s-off/hboot s-off))
:|)
well it's not exactly a permanent solution just a temporal way to root my phone, but in worst case i think its nessesary to reinstall win7 on your pc....
