[Q] Fastboot problem

hello,
I'm hoping someone here can help me sort out my current problem.
I've been trying to root so I can install the latest ICS port, but having problems at the Fastboot screen.
I apologize in advance if some of the references/names I'm using are incorrect.
So, I had originally unlocked my Nexus S sometime early this year. When I restart the phone, the "unlocked" lock picture shows up under the "Google" words, and when I go into fastboot mode, the Lock State is Unlocked.
I'm running 2.3.6 right now on the Tmobile version of the phone.
When the phone is on (not in fastboot mode), I can execute ADB commands and the device is recognized. As soon as I go into fastboot it isn't.
I'm running 64bit Win 7, and I have gone through the various threads that have listed this issue, and installed PDA Net drivers and still there is no solution.
In Fastboot mode, while connected to computer under device manager, it shows up under Universal Serial Bus Controllers as an Unknown Device... I'm unable to update any drivers for it, and even when I try to manually update the drivers by going to the PDANet drivers it does not allow it.
When the phone is on in regular mode in device manager it shows up as Android Phone and within that it has a listing called Android Composite ADB Interface.
As mentioned above, when phone on in regular mode everything is detected.
I installed clockwork app from market, assuming that the phone was "rooted" based on the "unlock state" in fastboot mode, but it immediately says that phone needs to be rooted because it was unable to find SuperUser file etc etc.
I've spent the better part of a few days trying to figure this out by checking all sorts of links, but I haven't found a solution. The main issue is that the phone is not being recognized when in fastboot mode when connected by USB. And I'm unable to install the proper drivers for fastboot mode.
Hopefully this makes sense, and someone can provide some insight.
Thanks in advance!

I'm not positive about this but couldn't you adb push the su binary and apk? I don't own the Nexus but I would think since its unlocked you could just push the files. If this would work I would think it's just a temporary solution to allow superuser permission. As I understand it, fastboot is the preferred method for the Nexus.

Did you try a fastboot command like fastboot devices?

Don't know if this applies to you but I had a similar sounding problem when trying to root my Nexus S where everytime I booted into fastboot mode I had an error message at the bottom of the screen saying something like 'fastboot status-fail Invalid command' and so I couldn't use any fastboot functions.
To get around it I used this one-click root . For some reason I got an error message halfway through for whatever reason and it wouldn't complete the root for me but it booted me into fastboot without receiving the error message and then once I was in I went and rooted manually.
The CWM is out of date on that site though (possibly the super-user zip too) so I replaced them with the latest versions and popped it in my dropbox for you, if you wanna try it out.

Edit: just had a little look through the bat script and the initial commands that got me into fastboot properly is (with your phone in debugging mode):
adb start-server
adb reboot bootloader
Click to expand...
Click to collapse
So you could try that first if you wanna go through manually.

Know that you can't run adb command while in fastboot mode. Boot into your CWM and then you can start an adb shell and you'll be able to push all the files you want and execute all the commands you need.
Fastboot mode is for running fastboot indeed. Try 'fastboot devices' while you're in the bootloader and see if devices pop up. If not, you really have to figure out your drivers issue. Maybe remove the device completely from your PC (including driver files) and reinstall it using the PDAnet drivers.

[Completed] Trying to Unlock HTC EVO 4G.

Hi. This is the original HTC EVO 4G that I got from Sprint.
Model PC36100
Android 2.3.5 with, I think, HTC Sense, though it doesn't say that.
Baseband version 2.15.00.01.15
Kernel version 2.6.36.10-g8b16b68 [email protected] #1 (9/4/12)
Build number 5.07.651.6 71ORD
My goal is to install basic stock Android on it. Whatever version will work, be stable, and run smoothly, support basic wifi, social media, email, camera.
It runs pretty nicely as is, really. But I imagine it'd be cleaner with basic android and not all the Sprint and HTC stuff on it.
I'm trying to unlock the bootloader using a Windows 10 PC.
I have tried various sources for the drivers. Currently trying HTC Sync for the drivers but have tried all the others.
What I'm observing currently is this: In DEVICE MANAGER, the phone when running in its normal Android mode, it shows up as ANDROID USB DEVICES > MY HTC. and it's running cleanly (no yellow exclamation point). IN that mode, I can open my COMMAND prompt and use ADB DEVICES and ADB finds the device HT06MHL01565.
In order to do the UNLOCK BOOTLOADER, you have to connect the phone to the PC in Fastboot mode. When the phone is on the Fastboot screen, Windows Device Manager, adds a yellow exclamation point to "MY HTC" device. At that point using the command ADB DEVICES yields no devices found. So I cannot proceed to FASTBOOT OEM GET_IDENTIFIER_TOKEN. Windows isn't seeing the device when it's in Fastboot mode.
I do have USB Debugging enabled and have tried it with Fastboot both checked and unchecked in the Settings >> Apps page of Android on the phone.
So, to recap, when the phone is in Fastboot, the PC doesn't correctly identify it and the ADB DEVICES command yields nothing.

Device not detected in ADB after rebooting to fastboot

I tried asking this in the forum for my specific phone (Sony Xperia XZs) but I'm having little luck over there so I'm gonna ask here.
I'm trying to unlock the bootloader hoping that I can root and install a custom ROM.
When the device is on, the computer can see it just fine, but when I reboot it into fastboot mode, it can no longer see it. I have all the necessary drivers as far as I know.
It still appears in device manager as 'S1boot Fastboot'. I seem to have no luck updating drivers there either if that is the issue. I choose to select manually and it narrows down under 'Android Device' to:
Android ADB Interface Version
Android Bootloader Interface Version
Android Composite ADB Interface Version
(None of them worked when I tried, unsurprisingly)

"Waiting for device" after flashing kernal and rebooting device

Hi all,
sorry if there is plenty of these threads already floating around but wasnt able to find a relevant one to my problem. I'm hoping someone here might be able to help.
This is the primary XZ rooting guide i have been following, with other supplimentary guides 1 & 2
These have been my steps:
- Managed to successfully update fastboot driver with "android_winusb.inf-file" from 'Google USB Driver' within android studio.
- Unlocked bootloader
- Installed AndroPlus Kernel sucessfully "fastboot flash boot boot.img"
Now went to reboot device as stated by instructions (mistake) and now the device is not recognized in cmd "waiting for device". I've replugged the usb in multiple ports and the device shows up as "android" in devices and printers. I go to update the android "SOMC Flash Device" to the platform tools directory but makes no difference in cmd. Still "waiting for device". In Device Manager there is no sign of the device either.
When the phone is turned on it shows your device has been "unlocked and cant be trusted will reboot in 5 seconds" then proceeds to xperia logo and freezes. With no recoveries theres not much options.
Is there a way to continue from here or even return to a previous state? It seems like i hit a brick wall. Please help

Installed adb SystemWide?
adb drivers are Installed corrcetly? , better to reinstall them.

[SOLVED] confused noob - adb/fastboot : install or just run?

Hi
Noob alert here.
I'm trying to flash a custom recovery (twrp) on a very old phone which has its bootloader unlocked. (the phone currently runs android 6.0, yes, that old...)
I read on the forums here that I need to use ADB from windows (Win10 here) in order to flash twrp onto the phone (to replace the stock recovery).
I DLed the neccessary files (platform tools), but it's just a bunch of files with nothing to actually install AFAICT...
MAny tutorials mention that I should just launch a CLI from within the folder containing the tools and then run ADB to flash twrp.
However, I get stuck at < waiting for any device > which, according to other tutorials, isa sign that drivers are not installed for my device in windows.
Some tutorial mention that I should INSTALL ADB (rather than just run it from CLI), so I'm starting to wonder what I am missing here.
- Should I INSTALL ADB? how?
- Should I install drivers for my device? It seems like my device is properly detected by Win10 and I couldn't find any driver to install anywhere.
I'm confused about what's going on.
Could you please help me out here?
Thanks a lot for your advice.
Best,

OK, I made a little progress I think. I'm not sure my issue is actually related to windows drivers but maybe I'm wrong.
Here's the deal:
When my phone is booted and connected to my PC,
adb device
spits up something : the phone is detected. Now after running
adb reboot bootloader
the phones reboots into bootloader mode (and displays the info that the bootloader is unlocked. But from now on,
adb device
in windows CLI outputs nothing : the phone is no longer detected.
Plus now the phone shows up as an unnknown device (fastboot2.0) in windows device manager. So? Missing driver I guess?
Running windows update found a driver for
Google Android Bootloader Interface
So I guess now it should work
I'll post the results
Thanks a lot

nope...
No luck
ADB still cannot see my device when in bootloader mode

Actually it works!
Even though
adb devices
would not list anything when the phone wwas in bootloader mode, I was able to flash twrp
problem solved!

In the future some commands in Bootloader Mode require fastboot oppose to ADB.
