Fastboot Drivers? - EVO 4G Q&A, Help & Troubleshooting

Okay guys, I'm not too new to rooting devices, esp. samsung / htc. For some reason I can not get my laptop to find my old Evo when its in fastboot mode. ADB see's it in the os (in debugging mode) but not in Fastboot. I'm trying to root it but of course this is causing an issue. My laptop cant seem to find drivers so I was wondering if anyone had a link for the USB drivers for this guy that will work on windows 8.1
the evo is up to date so I'm hesitant in following an older root method. 2.18.001 if i remember correctly.

Because you have Windows 8.1, you'll need to run a USB trace and report it back to Microsoft so they can provide a hotfix for your fastboot driver.

[Q] Soft bricked i9250 international

Hi and thanks for taking the time to read this
My brother tried to do the update of his nexus through the phone download (not through the sd card or connecting to a computer). Since this it will not start up and if i go to download mode it says that it is downloading constantly (have left for hours).
I can make it to the clockworkmod recovery v6.0.1.0 but unfortunately my brother didnt make a backup before trying to update to 4.2 jellybean.
The unfortunate part of this equation is that i cant access the phone via usb as the drivers wont install and the phone doesnt have an sd card slot except the sim card slot. So placing the correct files on the phone is proving too hard for me to complete.
Sorry if this situation has been covered before but i have searched for about 1.5 hours now to no avail. I would very much appreciate if someone can take me through how to get this phone working in any way possible (i dont care if he loses all data and goes back to stock).

CWM recovery offers the ADB interface. I would:
1. get the naked driver package (see Efrant's guide)
2. boot device into recovery and connect usb cable
3. open windows device manager, find your device and manually update the driver
4. use adb to backup the /sdcard to your computer
5. flash 4.2 stock images using fastboot
6. done

op, if you just want to get the device to working state again, and dont care about any data:
1. get the naked driver package (see Efrant's guide)
2. boot device into bootloader and connect usb cable
3. open windows device manager, find your device and manually update the driver
5. flash 4.2 stock images using fastboot
step 3 is the same, the same procedure, the same driver; windows is dumb so you have to tell it again when device is in bootloader (which, btw, is NOT the same as download mode).
Hi and thank you for the replies.
I have downloaded the naked driver but cant get it to work. I have followed the steps to make it work but i get to the device manager and there is no option for uninstalling current driver (as it has none currently). It only has update driver software (which if i use windows to search for it cant find any) and properties. The Galaxy Nexus icon in the device manager has the yellow exclamation mark sign on it. I can
When i try to manually find the naked driver it comes up with the following error
Windows found driver software for your device but encountered an error while attempting to install it.

Where to from here lads, i appreciate the input

if you're using windows 7, i read something about you need to disable windows digital driver signature check, or something in those lines.
can't help any further on that subject, since i'm a Linux user (Windows knowledge is very limited) and also that is an operating system's issue and would be better discussed in a Windows forum, IMO.

Thank you for another helpful reply! Yes i am using windows 7 - i will try to perform the task now - results soon. In the meantime if anyone else knows instructions on how to do this i would love to hear
I am at work and dont have administrator settings on windows 7 so i went to an older computer and started fastboot.exe. I went to recover and there was the IP address of the computer went to that and recovered. From there i went to reboot and now i am just getting a Google in the middle of the phone (as before). I will wait some time to see if it will start up now. If not what is my plan?
So i havent got any closer to having a usable phone.
Im up to this step:
"flash 4.2 stock images using fastboot" how do i do this? i have fastboot and i have the stock image

Windows 8.1 Fastboot

I'm on a fresh install of Windows 8.1
Here's what I did.
1. Installed HTC Sync Manager
2. Installed Minimal ADB and Fastboot
3. ADB works fine, boot into bootloader.
4. Windows shows Unknown USB Device (Device Failed Enumeration) in Device Manager
Running fastboot devices returns nothing
I can connect my phone to view files, I can ADB on my phone, the only thing I cannot do is fastboot. Why is this happening and how can I fix it?

From all of my research, you're the first person I've heard of having it working. Any specific drivers used? I'm very curious (currently, I have to use a backup machine to push TWRP updates to my VZW One)
Same thing here. 8.1 broke fastboot. Is this a Microsoft problem specifically because if it is I seriously doubt they will be in a hurry to patch it.

I have found out something based on the VMware experience. Can somebody try it out and report back???
I feel that the fastboot problem in windows 8.1 is related to the USB port.
For those people that having problem, are you guys using USB 2.0??? If yes do you have USB 3.0 port in your computer??? The real problem maybe is that fastboot only works with USB 3.0 but not USB 2.0 in windows 8.1...
I tried both USB types, and half a dozen drivers and workarounds, and nothing.
I don't believe the dude above got it working. He is probably thinking Win 8, not 8.1. I have it working on 8.
Flash Image GUI will probably do everything you need to do in fastboot without the need for a computer. I just threw 8.1 on one of my extra PC's, I'll see if I can get the drivers going. I feel like this was answered in another thread though, I think it is in the rumrunner thread...

i just used http://www.droid-now.com/2013/10/fix-working-fastboot-drivers-windows-8-1-x64/ and fastboot works on a 3.0 port on 8.1
I've just had this problem last week, and now got a solution...
Hi guys,
For anyone interested, due to something DreamerTKM said - I tried both USB 2 & USB 3 sockets on my Dell L701X laptop and both failed:
ERROR: Unknown USB Device (Device Failed Enumeration)
I did a clean install of Win 8.1 Pro and it still failed...
Anyway, I was using Windows 8.1 Pro default drivers for my system when this issue came up last week - default as in Microsoft's own out of the box drivers (drivers on the install DVD and Windows Updates) for my CPU chipset, USB chipset, etc... - my entire system (except for my nVidia graphic card!)
My laptop is now a few years old and my official "Dell" CPU chipset drivers are not compatible with Win 8.1, so I need to rely on Microsoft for these, but my USB 3 originally had Dell supplied "Renesas USB 3" drivers which I hadn't installed or even thought about installing as my USB 3 socket worked - and worked well...
...anyway, after installing the original Renesas USB 3 drivers the fastboot commands work once plugged into a USB 3 socket! USB 2 still wouldn't work though, but now my Win 8.1 laptop can do fastboot commands through a USB 3 socket.
I understand not everyone will have a Dell L701X laptop but the moral here is before blaming Microsoft and their Windows 8.1 O/S (which is truly awesome), try installing the correct drivers first!
DreamerTKM - thank you for putting me on the correct path with this!
Hopefully this post may help some of you!

guyz if u r working on win8.1 just plug it in ur usb 3.0 then it will wrk...if u put in usb 2.0 it wont!
No changes. I have read a few topics that it barely works with Win 8.1, so I will have to try it somewhere esle with Windows 7, then I'll be coming back to tell what's up.

Full fastboot and ADB support is available in windows 8.
Watch the first video: http://forum.xda-developers.com/showthread.php?t=2703585
I have been using fastboot and adb with no problems on Windows 8.1 since January. But the issue is much more than simply using a different USB port. Here is the tutorial I used. http://www.droid-now.com/2013/10/fix-working-fastboot-drivers-windows-8-1-x64/ Certain security features of 8.1 need to be bypassed to install the modified drivers. Also see this guide: http://forums.team-nocturnal.com/index.php/topic/1362-how-to-adb-fastboot-in-windows-xp-7-81/ I used this just for ADB, but it looks like he's updated his guide for fastboot as well. Hope this information helps.

Stuck in mini pooploader (Blue Screen)

I followed the instruction for this link. (http://forum.xda-developers.com/showthread.php?t=1347321) Everything was going well. Now I can't get out of mini pooploader. I searched around and was suggested from other peoples issues that I need to install the drivers. I manually installed the drivers, supplied in the link and Windows 7 states that the drivers I have are up to date. DO I need to go to HTC and find there drivers (Which are windows based or find android drivers)
I recently upgraded my XOOM to KIT KAT and am happy with it. I had fast boot and ADB installed for that project. Is that what the problem is? I have co-mingled the downloads for the NAND install with the KIT KAT ADT Bundle?
I have no problem running ADB and seeing SDK recognize the commands. When I try Fastboot commands I get waiting for device messages. Can someone please point me in the right direction. I know this is an old thread and Im hoping someone will be having so much fun this holiday weekend that they'll hop online and help. I hope this use the phone in conjunction with the updated Xoom.
Oh yeah, Thanks to all the VETS out there

Thanks for replying. That's the guide I was using. I can't get into fastboot. ADB commands work. I tried to manually install the drivers (On the computer). Windows 7 says my drivers are up to date. I can't move forward out of mini pooploader (funny name by the way). Any ideas would be appreciated...
I meant to say that I found that thread after being stuck in mini poop mode.
9. Turn the phone back on. You should see a blue miniPooploader screen with a lot of white text scrolling for a moment. When it gets done, pull the battery to shut it off. Then replace the battery (it should still be off)
10. Connect the usb cable between the phone and the PC, and turn the phone on. The PC should see the device, and may or may not assign drivers to it.

have you done this part? when you do the 10th one, your phone should get a black screen and a driver should be automatically installed by windows 7. for me - the driver was HTC Bootloader. after this, i installed the fastboot driver. more specific - the driver in the ADB_fastboot folder. after that - it went smooth.

I followed your advice. I let mini pooploader run the blue screen with white letters. Once finished, I removed the battery, placed the battery back in and then plugged usb into computer. I then powered the phone up with the same results. I performed this task 11 times with the same results. No black screen and no win 7 driver install. The computer says unknown device. I have tried to install drivers and computers states the drivers are up to date. I have tried different USB ports. I have attempted to install HTC drivers someone posed in this forum as well as the drivers that come with SDK with negative results. I have tried to uninstall the drivers in hopes that windows would install upon recognizing device with no luck.
Any ideas? I really need to get this working. i have not had a phone for a week now

[Q] ADB not recognizing device

I just bought a new computer yesterday, after installing the lightweight adb/fastboot program to my dell inspiron windows 8.1 laptop. I realized when I try to see the devices connected to adb by the command : adb devices, the only that pops up is list of devices attached, but show nothing. Here's the guide I followed http://forum.xda-developers.com/showthread.php?t=2778239
I'm guessing it has something to do with the drivers.....any help appreciated......
Here's the link I used to installed minimal adb and fastboot http://forum.xda-developers.com/showthread.php?t=2317790
Try uninstalling HTC Sync and any HTC drivers, then try to re-install, and see if that helps.
If no, uninstall any HTC software and drivers. Connect phone, go to Device Manager, and see if the device shows up. If so, select the option to manually select drivers (ignore any prompts to automatically install HTC Sync, etc.) and pick the Generic Android MTP drivers.
See if that works, although Win 8.1 has been known to be more problematic connecting to this device than previous Win builds.
Well I finally got it to work..I never installed the HTC sync software. I found a good link of compatible drivers for my 8.1. I didn't realize the phone had to be in bootloader mode to use fastboot commands though. That's a new thing forbme. If I remember correctly, I could use fastboot commands while the android was in its GUI/ROM format...
I've already switched cid yo gpe cod, but I'm probably going yo switch to dev edition

Fastboot commands only work in fastboot mode. Its always been this way.
adb commands work in the OS or recovery, but not in bootloader or fastboot.
For some reason I was thinking the opposite...god, I'm retarded. I went ahead,and downloaded the entire SDK anyhow. Everything's up to speed

My tablet is stuck as an unrecognised USB device by Windows 10.

Hi there. Sorry if I sound dumb. I'm new to this whole thing and this was supposed to be my first experience with flashing custom ROMs and stuff like that. I was planning to get ready to install LineageOS on my Nexus 7 using a Windows 10 PC. Unfortunately, things quickly went south.
My first roadblock was the tablet not being recognised by fastboot. I checked online for a bit and from what I could gather, the solution was to install the Google USB drivers using device manager. I went into device manager, right clicked my Nexus 7 in "portable devices", selected "update driver" and chose the Google USB driver I downloaded from the official Android developers website. I'm not sure if this is relevant but the tablet was in fastboot mode when I did this. From that point on, my tablet is no longer recognised and it just keeps saying "device descriptor request failed" whether it's in fastboot or normal mode, and regardless of which USB mode I choose.
I tried uninstalling the driver, factory resetting, WugFresh NRT, and using different cables and USB ports. I checked for all sorts of solutions but they either didn't help or they require an unlocked bootloader (which was the very first thing I tried to do before finding out I needed to install the driver for fastboot to recognise the Nexus 7). Does anyone here know of a solution to get this working again? I'm completely stumped on what to do.
EDIT: I tested with a Chromebook and an old Windows 7 PC I had lying around. Neither could detect my Nexus 7 and the W7 PC even said it failed to install the driver as soon as I plugged it in. It seems that the driver update screwed up my tablet somehow and I have no idea how to fix it. I really don't understand how this could have happened considering I followed Google's own instructions for updating the driver.
Does anyone perhaps have a copy of the OEM driver for the 2013 N7 Wi-Fi (flo) model? ASUS don't distribute the driver on their website anymore and I'm out of ideas.

Review this thread and the solutions.
After you have fixed it, you can easily install a new custom ROM with two steps:
RESTOCK - installs USB drivers and unlocks it, latest official stock ROM
CROSS - various custom ROMs, 1-click installation, TWRP, incl root

Thanks for the response. I don't think I'll have enough time to try this today but I might as well ask. Do any of these fixes work without needing a USB connection to a PC, or if they do, do they require adb and fastboot to work? Because if so, I won't be able to use them since my USB data connectivity is completely busted no matter what I plug my Nexus into.

I just ran the RESTOCK 1 script and it worked wonders! My tablet's USB connectivity has been fixed and as an added bonus, my bootloader is now unlocked. I'll be continuing the process in Linux on my Pixelbook since it doesn't require any driver installations as far as I know. Thank you so much! You're a life saver!
