Afternoon all,
I debranded my desire using an RUU flashing it to 1.15.405.4 but now HTC Sync isn't recognizing the phone, it is just coming up as 'Disconnected' yet it is still being recognized as a removable disk when in disk drive mode so it can't be a USB brick.
I can't get ADB working either since the phone isn't being recognized so it isn't installing the required ADB drivers for the phone. I can't go back to my stock firmware either because USB Debugging has to be installed correctly for the RUU to run. I had no problems initially, but after upgrading to this ROM I have seemed to have this problems.
I want to root, but if I can't have access to the ADB a root would not be possible? Please correct me if I'm wrong.
If anyone has any advice I would be glad to hear it. Thanks
I have the same problem with HTC Sync - just can't get it to see the phone. Hopwever to get ADB working make sure you have USB Debugging turned on in the settings under Applications / Development / USB Debugging.

Thanks for the reply.
I have USB Debugging turned on in the menu, but it seems to not be recognized. I have done all the command prompts in cmd, but it doesn't list the device under ADB devices. Hmm.. :/
I had the same problem after all my updates, that worked for me, restart your pc and restart the phone, leave it plugged in by usb, it worked every time for me, hope that will help.
I restarted my computer then phone - leaving the USB plugged in, but it's still not being recognized. Am I doing the steps the wrong way round?
It's annoying because this is stopping me from rooting at the moment and I really want to get my hands on froyo!
Thanks
I'm not to sure I'm a newbie to all this, what I did was tun the phone and pc off, turn the phone back on first then turn the pc on as soon as the pc detects the phone put the phone on sync, and so far it always worked for me after a update, maybe you have a different problem maybe a proper dev can help you out.

Tried the above a couple of times, no luck. Thanks for the help though.
Hope someone knows a fix cause I'm eager to root my phone and get onto some froyo goodness! haha

The HTC drivers are pretty damn bad with regards to Sync. I always do adb-related work in recovery for that very reason - I can almost never get Sync working.
Can you get adb working in recovery?
Ok here is what worked for me
1- Uninstall the HTC sync and the HTC drivers
2- open MSConfig and disable all non microsoft services
3- restart windows
4- install HTC sync
5- Connect the phone and it will connect
6- re enable the disabled services and restart Windows
Does it work normally every time after that, or do you have to go through that jazz every time?
Hopefully it works every time - I'll give that a shot if so.
Hi,
The ADB isn't being found in Command prompt it outputs 'list of devices' but there is no device listed. All drivers are installed as well.
I will try the above and see if that helps.
Cheers
Hi Matey, I had this exact same problem after rooting my desire last night - basically check task manager for any adb processes and kill em, if that still doesn't work re-run the htc sync install and select repair and it'll be ok again.
I had to do this on my home laptop which I used for the root, but also on my works laptop even though this was turned off and not used for rooting at all so think it's an issue with htc sync not seeing the same phone, but at the same time seeing the same phone and getting confused.....
so - reinstall using repair and reboot and all should be well matey...
Thanks for the help guys.
I had to reinstall Windows for other reasons, and after I reinstalled HTC Sync it still wouldn't recognize the phone but ADB is working so I can do all the shell commands.
Cheers for all the help.
I take my above post back. The phone is now not being recognized by ADB, it seems to have occurred after I have turned my computer back on. Windows installed some updates and I'm wondering whether they might have had an affect.
Anyone had any experiences in the same sense?

"USB Device Not Recognized"
I have searched for so long trying to figure out what's wrong. I'm out of idea's on how to fix it, nothing will recognize my Evo.
Tried on 4 different computers, two of them running 7, one running xp, and last running vista, all say the same thing, computers not the problem.
Downloaded htc sync, disabled/enabled usb debugging, restarted the phone many times, restarted computers, and even changed the default usb connection to HDD and HTC sync.
I rooted using the idiot proof guide and used the Sprint Rom he linked in the guide. Would love some help. Thanks!
Try downloading the auto sync app in market
And let me know what happens.

Just tried that and still not recognizing it.
Which HTC Sync did you try? I think the latest is 2.0.40
http://www.htc.com/us/support/evo-sprint/downloads/
set the EVO connection type to HTC SYNC and USB DEBUGGING ENABLED.
Assuming you've used ADB, what response you you get from
ADB DEVICES at the command prompt?
you should get something like
C:\>adb devices
adb server is out of date
* daemon started successfully *
List of devices attached
HT05EHL10353 device
and we will know you have a good physical connection to the computers. If it doesnt show up, try a different USB cable....

Thanks for the help! I checked for my device in ADB and it does not list it, so i guess my cable is probably bad. I'll go out and buy another and hopefully that fixes the problem.

When i connect my phone in recovery mode, it still just says device not recognized, so i can't really do that.
Sorry but bump, i relly need help with this.
It still says unknown device when i try to connect my phone in recovery mode.
Go into your computers device manager and uninstall the device and htc sync, then reinstall sync and make sure usb debugging is on then plug it in
Edit: sorry, go into the device manager with it plugged in. if its not there (should be a yellow or red triangle next to it or neat the to as a HID) them it could be your cable or phones port.

Just tried that and it's a no go, still the same problem, Also tried another cable today and that didn't help either.
I have light leakeage at the bottom of my phone, so i think i'm going to take it in for that and just get a replacement.

I think you need to pay closer attention to the guide, because this statement makes no sense in reference to the guide.
The guide is helping you install ADB drivers, you don't need to do anything in ADB while your phone is in recovery in that guide.
Could be wrong, but I'm still fairly certain that the guide will fix your issue, because I had the same problem.
It's as simple as you do not have the correct, or any ADB drivers, therefore your phone is not showing up as a device under ADB. Once you have the proper drivers installed, your device will show up.

I followed the simple guide step by step.
When i boot into recovery mode i end up with this in the picture.
His recovery mode shows an Evo with a little exclamation mark next to it, i'm guessing what i got is still recovery mode. But still if i plug my phone in my computer still says unknown device, so i can't install ADB drivers.

You just have a different recovery. Once you are in recovery, you don't need to do anything else on your phone specifically.
Instead, connect your phone to your PC via USB if it isn't already and open up device manager on your PC and follow the rest of the guide.
Edit: Where does it say unknown device? In Device Manager?

It shows up in usb controllers instead of other devices as he shows in the guide. If i try to update the driver it just tells me it's already up to date.
>Sorry yea it does say unknown device in device manager.
Gotta bump, would really love to just fix this instead of driving 30 mins to a sprint store.
So i followed the guide for installing apb drivers, but even in recovery mode my phone still shows up as unknown device in device manager.
Ok, well I just ran into this myself on my secondary computer. Have you tried a different USB port on your PC?
My front ones were giving me unknown device, but as soon as I plugged it into one of the ports on the back of the mobo ADB showed right up in device manager.
Factory reset it and get it exchanged.I belief is the SD card failure issue.

I have the same problem and posted this question on 3 forums including the HTC support forum and nobody has been able to find the correct solution.
I know the cable and the port is good because I can connect my Samsung Moment to it and it works perfectly. On the Evo, I've downloaded the latest HTC Sync from the official HTC site, tried the one on the microsd card, checked and un-checked USB debugging, and still it doesn't connect.
The Evo won't connect to my Win 7 computer at home, Win XP at work, but it will connect to my daughters computer which is running Win XP also (all 32 bit).
I bought this Evo from Best Buy exactly 28 days ago today. Do they give you 30 days to return it, or is that only the Sprint store?
They do give u 30 day trial.go get it exchanged or...........

For some odd reason, I lost adb functionality (i.e. any adb command issued receives "error: device not found"). I looked in Device Manager and noticed that MyHTC was gone! I looked at my phone and USB debugging was enabled and in charge only. I could put it in USB Drive mode and the PC would recognize it as a USB Mass Storage Device so that I could exchange and view files but no adb.
I searched and searched on this issue for hours and installed over a half a dozen "androidusb.inf" driver files several times over. Every install generated the Code 10 error where Device Manager was lacking some information from the driver file and could not start the device. I reinstalled HTC Sync and gave that a try...nothing. Downloaded USBDeview and uninstalled all HTC drivers including the HTC Android USB Device and tried again to no avail. WTF?! What else am I supposed to do?
Well, in a "what the hell, let's give it a try" kind of moment, I decided to toggle the USB debugging off and then back on (and yes, it was checked and on the whole time). WORKS!!! WHAT THE CRAP?!! MyHTC is back in Device Manager and everything is back to normal. I'm glad but irritated!
I share this story in hopes that if someone else stumbles on this problem, they will not have to go through the same headache as I did. Just thought this was odd considering how many times I have plugged and unplugged and never had any problems with adb.
Toggle USB Debugging....so simple. *rolleyes*
Same Issue
I've got the same issue on my EVO 4G. Just installed the latest CM7 and now it tell me device not recognized. If I manually install the drivers it gives me the same code 10. I can't bring up the phone as a storage device and toggling the debugging is not working. Any ideas?

You installed the hboot drivers correctly?
Boot into recovery, with usb debugging enabled, connect to pc, it should install the drivers.
Still the same
Even when I reboot into recovery it still gives me "USB Device not recognized." I previously had MikFroyo on my phone with no problems. I'm at a loss.

You most likely have a bad cable, do you have another one you can try?
Possibility
Not at the moment but that may explain it. Still seems weird for it to just go out right as I change to CM7, but still a possibility. I am going to run and grab my other cable. Thanks for the advice.
No Luck
The new USB cable didn't fix the problem. Also, in device manager, even with the driver installed its labeled as "unknown device."
If I boot into hboot the computer recognizes it.
**update: After rebooting from the hboot, my phone is recognized by the computer however, a disk drive is not coming up in "my computer." I have USB storage turned on but Im not getting anything.**
Any help would be much appreciated!
Sad Day
Apparently the Micro USB port on the bottom of my phone is going bad... I talked with some other people who've had the same problem. HTC knows that the ports aren't very sturdy as well. Well... sad day for me.
Also if you're getting the notice from windows saying that you your device will run faster in a 2.0 usb port and you know the port is 2.0 ... chances are your port is going bad as well.
*****UPDATE*****
Flashed to MikFroyo and none of the above stated problems. I would venture that it was CM7 but apparently everyone else is able to use it so who knows.
Guys, I need a little help here. I've rooted my share of phones, and even some tablets, but the Evo i bought a few days ago has been a nightmare.
For some reason, and I can't tell why, this thing will not be recognized by Windows.
It always shows up as "Unknown Device" under the USB catagory on Device Manager.
I've tried different OS versions (Windows 7 64Bit, Vista 64bit, Even Mac). I've also pulled down every form of driver I can think of (SDK Orginal version, HTC Sync, Hboot Versions, etc.)
I just cannot get this thing to be recognized. And if I manually try to update the driver and point it to one that I've downloaded, Windows tells me that the most current driver is already installed.
The bottom line is that I need to be able to connect to the phone from the comp in order to push stuff via ADB and throw commands at it. The same unknown device situation happens when the phone is in bootloader or actually booted into Stock Froyo (2.2)
Has anyone ever seen anything like this? I know i haven't, and it's buggin me out.

I've never seen that before. Wish I had something for ya. Is the Evo brand new or used? Are you sure the usb cable is good? I've seen a bad cable cause some headaches before. Wish I had more for ya, sorry man.

EVO is not new. I bough it from cragslist a few days ago. It seems to work fine otherwise. Not rooted for sure, and running Sprint original 2.2.
I did try a couple of different USB cables just to be sure, and had the same results.
The funny thing is that even though I was never able to get it "recognized" on any of my machines, I was able to get ADB so "see" it for a while. I started the rooting process by pushing files to it via ADB and even sent a reboot command to it.
Once it rebooted, that's when it all went bad. It was still showing as unrecognized (just like before), but now ADB can't see it at all. Keeps telling me no devices are connected.
Even my friend's Mac Air (which supposedly doesn't need any kind of drivers to see the phone) can't see it either.
It's just weird...
perform a hard reset, maybe a rogue app or setting got messed up,
fastboot screen>clear storage>yes
Tried that as well. Sorry i didn't mention it in the original post.
I think I've pretty much tried everything that's somewhat logical at this point.
Now I'm looking for the "illogical" ideas.
Make sure usb debugging option is turned on in settings>applications>development and the phone is in charge only mode. Then it should be recognized and you should be able to use adb.
Debugging was turned on already. I made sure of that.
As for the mode of connection I've tried them all with mixed results.
Here's what I've seen so far...
Charge only - unrecognized device in Device manager, and ADB can't see it.
HTC sync - unrecognized device in Device manager, and ADB can't see it.
Disk Drive - unrecognized device in Device manager, and ADB can't see it.
Internet Sharing - never tried it.
Here's the weird part. If i uncheck Debugging and set the phone to HTC Sync, I am sometimes able to get ADB to see it.
This is just confusing...
What happens if you uninstall HTC Sync and just leave the drivers installed? Could work I suppose. I know unrevoked says to make sure you uninstall HTC Sync and install the ADB drivers.
try this. connect your evo to a machine running xp. i had the same problems rooting one evo using windows 7. connected to a machine running xp ,zipped right through without a hitch.
HOPE THIS HELPS YOU IN YOUR QUEST
Thats what I tried on the Vista box.removed HTC sync, and left the HTC drivers.when that failed I removed the drivers too and replaced them with several different ones I found online.none seemed to work.
The strangest part is that all guides seem to say that MAC OS should just see it without any drivers.
I borrowed friends MAC air and it didn't see it either.
I'm not sure which USB drivers you are using, but these work for me. Uninstall the drivers first, then install this. I hope it is legal to put these here and if not I am extremely sorry.
PS you could try a Linux Live CD and it will see it without drivers or go with Wubi which installs Ubuntu on your Windows hard drive and can be uninstalled just like any other program. It gives you the option to boot into Ubuntu or Windows on bootup. Neat little program and it is faster than using the live CD. Go to this link Wubi and click the Start Download button to download Wubi.
Those seem to be the same drivers I've tried (well those and a ton of others as well).
I'm gonna give that LiveCD idea a shot. Burning it now.
If not, I'm gonna try to find an XP machine somewhere.
I've got a couple of VM's on my machine running XP, but since the main Win7 Machine doesn't see it, it can't seem to pass the USB connection over to the XP VM.
Man, I have to say, this is just the most complicated rooting process I've ever seen. If this was my first root attempt, I'm pretty sure I'd leave Android forever
It usually is a painless operation to root the Evo. For some reason you are having a difficult time with driver installation. It seriously has to be something simple that has been missed, because I have rooted mine and several friends Evo's and it was very easy. I had a MyTouch 3g 3.5mm before this Evo and talk about a pain. Before the Universal Auto root app you had to make a gold card first and that in itself took over an hour. It was my first root and it was very difficult and time consuming, so to see how easy the Evo was no matter which way I do it made me very happy.

yes the mac doesn't require additonal drivers to run adb however u need to make sure the directory is properly set in terminal so adb knows where to pull commands from... on windows did u try uninstalling everything phone related? SDK, HTC Sync, the whole nine yards then try reinstalling only the sdk and the usb drivers? I know with the lastest SDK the usb driver is not included for some reason or at least it wasn't with mine... then one day my adb just randomly stopped working and a uninstall/reinstall cleared up everything... try this usb driver and see where it gets u. Don't know if it's any different that wat the guy above posted but worth a shot. Reinstall the appropriate SDK first then i would recommend plugging the evo into the pc with no usb drivers installed then when it cant automatically find the drivers direct it to the file u downloaded and it should pull the necessary drivers from there and see if that does the trick...

No dice so far guys...but i have made progress in identifying the issue (sort of).
So here's the deal - the ONLY way the phone is recognized is if i toggle the "debugging" setting.
If i plug the phone in with the switch set on (meaning USB Debugging enabled) the phone is not recognized. Pointing the unknown device to the drivers (any drivers) does nothing.
However, if i plug the phone in with the switch set off, it finds a usb mass storage device. Then i turn the debugging switch on, and it finds the ADB Android phone with no issues. Then i can push commands via ADB without any problems.
The problem i have is that I cannot toggle that switch if i boot into HBOOT menu. So the comp never see's the phone.
I've tried this experiment on Win7-64bit, Vista-64bit, XP 32bit, and even MAC.
The same situation seems to apply everywhere, and with all of the drivers I've tried. None of them seem to allow the phone to be plugged in and automatically be found. The only way for the comp to see the phone is if i toggle the debugging switch off, then on.
At this point, I'm ready to put out a bounty on this. $20 via PayPal to anyone who can walk me through it. Bottom line is that I need to be able to see the phone without having to toggle the debugging switch. That will allow me to boot into HBOOT and still send commands to the phone via ADB.
Thanks for all the help guys. Hopefully, we can get this resolved.

Anyone care to take a shot??
I just purchased an HTC M8 running software number 1.55.631.4 and I am using Windows 7.
- I first tried plugging in the phone via usb, and Windows notified that the driver install failed.
- Then I tried installing the drivers manually using the All in one toolkit, tried plugging in the phone, and nothing happened.
- Then I uninstalled the driver, and tried installing the HTC Sync Manager (driver included), plugged in the phone, and still nothing happened.
- This problem occurred on an HP EliteBook, so I tried on another HP laptop I have at work, and the driver install failed when I plugged it in as well.
- Now I am here.
Does anyone have any possible ideas/solutions? Any feedback is appreciated.

Install HTC Sync Manager, then uninstall it but leave the drivers. Should then work fine
http://www.htc.com/uk/support/software/htc-sync-manager.aspx
I'm running into the same problem. Have just unlocked bootloader and rooted the phone. I now want to achieve S-OFF. However when I get to the ADB push command nothing happens. I notice the error "HTC MTP Device - Failed" when it tries to update drivers after passing command adb reboot. Tried installing HTC Sync and uninstalling a few times but stuck in the same place. Any way around this?
Thanks

I just tried this, and it didn't work. When I plug in the phone via USB, my computer doesn't even make the notification sound that something has been detected. The red light on the phone shows its charging, but my computer doesn't even show that anything was plugged in or detected. Could this be a problem with my computer?
If another computer works, then yes

Nothing in device manager either.
I do have my Nexus drivers installed. Do you think that could be the problem? Should I uninstall everything previous?
I tried installing HTC sync manager on my work laptop (which has no other phone drivers installed), and it's still the same problem. One thing I've observed though is when I leave the phone plugged in to the computer USB and do a reboot on the phone, the computer detects it at the startup "htc one" screen, but the device disappears seconds later as the phone continues to boot. It's like it detects it initially, then some software with the phone is causing it to fail. Any ideas?
bump.. went through HTC customer service and they pretty much got me to try reinstalling drivers, sync manager, etc.. didn't work. Said they would push me to the next level tech support which would be as long as 7-10 business days and that was last Monday and still haven't heard anything
OK using a windows 8.1 Pro laptop, ADB installed properly with HTC Sync Manager, both Windows, HTC Sync Manager and the Device Manager in the Control Panel can see my phone. I tick on USB debugging and then press revoke USB debugging authorizations. Unplug my phone and plug it back in. I'm using the original USB cable from HTC. Everything pops up and shows like it's connected, except when I type in
Code:
adb devices
in the command prompt, then it just comes up blank. I've attached screen shots so you guys can see what I am talking about. If you have any ideas it would be much appreciated. I've attached some photos just to show that I've dotted all my i's and crossed all my t's as far as I can see. I also want to point out this is the second computer I've tried this on.

1) Unplug the phone from your computer
2) Uninstall anything related to HTC (drivers, sync managers..)
3) Reboot the computer
4) Install the latest (direct URL) HTC Sync Manager
5) I tend to uninstall the manager right afterwards (optional)
6) Reboot the computer & plug in your device
7) Report back

Yeah that didn't work, I even tried installing the USB Driver manually and that didn't work either. Still comes up as not connected, it's super frustrating.
Not sure if this helps but for some reason my Android Phone isn't showing up under Android phone in my Device Manager, it's showing up as Portable Devices. I don't know if this is an issue or not, anyone care to give an opinion?

OK using a windows 8.1 Pro laptop, ADB installed properly with HTC Sync Manager, both Windows, HTC Sync Manager and the Device Manager in the Control Panel can see my phone. I tick on USB debugging and then press revoke USB debugging authorizations. Unplug my phone and plug it back in. I'm using the original USB cable from HTC. Everything pops up and shows like it's connected, except when I type in
Code:
adb devices

That's normal as the phone is using MTP, the Android Phone entry only appears once the drivers are installed. It's definitely a driver issue but as to what I can't say as I have no issues on my 8.1 Pro laptop
I think I figured something out, just flash CM 12 - (God it's amazing. ) and now I can see my phone on ADB, so whatever ****ery was going on I am blaming it on HTC stock rom.

is cm12 worth the hassle?
Sorry for the necrobump, but I ran across this thread while researching the same issue on my M8 and wanted to save anyone else the trouble if they also stumbled across this same issue.
Though the solution discussed would likely work, if you don't want to hassle with a new ROM, it is possible to fix it on your existing ROM provided you have root.
[SOLVED] ADB 'unauthorized', no RSA prompt, and no 'Revoke USB debugging' option

Thanks for this guide you put up. Interesting that there was no option for you to revoke USB authorization. My device is S-ON and have been using Viper for a while with the option available. Same for HTC stock. Good for you getting that fixed. Had a similar issue on a different device months ago.
