[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.

[GUIDE] V20 Fastboot access in Windows.

So I'm seeing a ton of posts of folks not able to get fastboot to see their devices. I've done some tinkering around and found a set of drivers that work fine for both ADB and Fastboot. (Attached)
Uninstall any ADB drivers you have on your system. Easiest way is to plug your phone in, go into device manager, right click your phone and select uninstall and check the box that says to remove the driver as well.
Then download this package, extract, simply run install.exe as admin. Don't panic, it doesn't do anything visual.
Now plug your phone in and see if adb works, you may need to authorize the computer again on the phone so make sure it's unlocked.
Reboot into bootloader and check if fastboot sees the phone by using
Code:
fastboot devices
If not then go back into device manager and right click on your phone, select update driver, let me select one from a list and you should see "Fastboot interface (Google USB ID)". Select this one.
Check fastboot without unplugging with the same command. Check and see if you can send commands to the phone by using for instance,
Code:
fastboot getvar unlocked
If the command fails, simply plug the phone into a different USB port and the same Google driver should install again and you should be able to send commands to the phone. Alternatively, you can reboot the phone by tapping the battery out and starting it all over again.
Now she chooches.
Lemme know if you're still having problems.

bless up ??

Does this work for sprint variant?

im having problems...damn it i don't get this
---------- Post added at 03:19 PM ---------- Previous post was at 02:42 PM ----------
any help please?

Verizon variant here,
I cannot seem to get this dang V20 in the right mode
(I've seen a bootloader or two in my day):highfive::laugh::silly:
I have used the adb command (several times)
Code:
adb reboot bootloader
to get it into bootloader mode, alas it is to no avail since all the command does is send the phone into "Restart" mode; nor can I get fastboot to recognize it when it is in, what I believe to be , the bootloader for said LG V20 of the
Verizon persuasion!​
Suggestions?

You need fastboot, not bootloader... To get it, turn off your phone, plug your LG cable into the computer, ( but not the phone yet) hold the volume down key for 5 seconds then plug it into your cable, do not release the button till your phone boots. It should boot into fastboot... Provided you have turned on USB debugging in developer settings (turn on oem unlock while you are in there too. (this is the way on the tmo V20 at least... If that doesn't work, I would use the dirty Santa guide

Not sure how I finally got it working for my Verizon variant as I tried like four or five different ways, but someone should definitely make a video.. Perhaps I will since I think visuals are a good aid to go along with written instructions..

Thanks bro works
Very easy
With my t mobile v20

My phone shows as connected in adb devices. I can also get it to reboot bootloader, but once im there.. I cant issue any commands such as fastboot oem device-id. It gives me the dreaded waitng for any device.

can't manage to make this work for H990DS, i don't get the usual authorization window to the computer, only get the window to choose which USB mode (battery charge, file transfer, so on...) I'm trying to get adb to work to activate agressive Doze on Greenify app, any help?

Thanks

TF700 - unrecoverable botloader error

Hello
I need help with my TF700.
I had this tablet for some time. It was unlocked with TWRP and ZOMBI-POP.
Last week I wanted to upgrade it for KIT-Kass 7.1
I wanted to update my TWRP for kang wersion ( 2.8.7.4) through TWRP and during the process it rebooted.
Then I've got a bootloop on normal starting. I can't get into recovery mode through power + vol up - tablet has no respond for that
I can only go to fastboot through power + vol down but when I connect it to windows with adb drivers or to linux(FWUL) it sees no device and no respond for any command.
Do You have any idea what to do ?
Thank You in advance

Sorry to say this but, if you can't send it commands then you are most likely hard bricked. What OS are you running on the computer with fastboot on it? - NP

This sounds not so good. I use windows 10 but as I said also I used FWUL to try.

Do you have access to a Windows 7 computer/laptop. There's an issue with Windows 10 and the fastboot drivers not working together, and causing a problem like yours. - NP

Found this in another thread, windows 10 fix. - NP
"I used Windows 10 and had to disable driver signature enforcement. Once I did this the PC recognized the tab without issue. "
To disable;

Thank You for the info, but I have laptop with Windows7 and still the same.
But if I have text on screen like this Starting fastboot USB download protocol can the device still be hard-bricked ?
Maybe I am missing some drivers ?

I would d/l Minimal ADB and Fastboot from here;
https://forum.xda-developers.com/showthread.php?t=2317790
and Universal_Naked_Driver_0.72 here; - NP
https://forum.xda-developers.com/showthread.php?t=2263822

For now the problem is I can not install the "naked driver" because devices manager can not see TF700 when it is connected, so I can't update the driver

Have you tried sending the [fastboot reboot] command to see if the tablet will reboot. When I bricked my TF201t my laptop didn't see it but it still took the commands allowing me to wipe the recovery partition and install the correct TWRP. - NP

Dear Guys
I know that this topic is quite old, but I am still fighting with this problem.
I tryied different drivers, 3 different computers ( two with windows 10 one with windows 7) and I can;t connect to fastboot.
The tablet is in this mode, but when I will use adb and type any command like fastboot reboot - it displays "waiting for device"
Do You have any idea what else can I try ?
Best regards

Hi,
me too! I was using it at lunch - no problem. Got home and turned it on and unrecoverable bootloader error.

No green android when using flash or fastboot mode

Hi,
First of all the bootloader is already unlocked.
Two problems:
1. - I was trying to flash twrp.img on my mobile but I am not getting that green android to show up in my screen all I get a black screen with blue led light, I usually power off the mobile, hold volume up and then connect the USB cable to my mobile.
2. - Can't find mobile device while using flash or fastboot, my mobile Developer option and USB debugging are turn on, mobile drivers and adb-setup-1.4.3 are installed, I have access to my mobile on my PC , when I do the process of flashing or fastboot I turn off the mobile and I unplug USB cable from my mobile, I press the keys to do flash or fastboot (I don't see no green android just a led light turn on) and connect the USB cable, problem is my PC can't find the mobile device, I use adb function eg. adb devices or fastboot devices I get nothing no device no info.
Is this problem with Win 10?
Was my problem understood in 2. - ?

Most likely a drivers problem, Windows10 fails to tell you that it's not installed the drivers that you pressed the install button on. It also fails to assign the right drivers when you add the phone in flashmode/fatsboot.
You will need to add them manually.
Go into safe mode and use 'driver signing disabled', try adding the drivers again. Then plug in you phone in flashmode/fastboot, then look in the device manager for the phone and change it
Several people have reported success with Zdiag drivers

Thanks! Great Info.
I removed the drivers manually in device manager and then used Zadig, now in command mode I getting something.
Next I have to figure how root the phone, do I need to flash twrp.img ?
I have all this stuff and I got confused which one I need to do next:-
boot.img
boot-G8141-47.2.A.10.45-hideunlock-rooted.img
twrp.img
twrp-3.2.1-0-maple
xperifix.zip
ss_maple.zip
zestmaple-latest.zip

Botched Graphene install on Pixel 3A - need help restoring default settings

Hello,
I am hoping for some advice on how to revert my phone back to its original "factory settings" after a botched instal of GrapheneOS onto an unlocked Google Pixel 3A.
I got to the point at which I needed to Flash the Graphene Rom to the phone, but rather than installing, I received a message from Smart Screen MS edge asking if I really wanted to run as it's protecting my PC - I clicked run anyway and a blank command line window appeared for a second. Now my pc doesn't seem to be recognising the pixel 3A when I type ADB devices. My phone is currently in Fastboot mode "unlocked" and I'm hoping for some advice on what to do next. I'm total noob, so unsure how to start the process over (return the phone to it's previous state) before, maybe, trying again on a different PC.
I have since turned on my phone and Android 11 is still present and seems to work fine (however it gives me a warning on startup that the bootloader is unlocked.
Any help would be very much appreciated - thank you in advance.

Is all what happened that your phone now:
complains about "'maybe not safe bootloader unlocked".
This is just what android does when the bootloader is unlocked.
This you did before trying the flash.
If you want the warning gone simply lock it again.
However if you into the market for graphene OS then I would recomend: along with following their guide to a t to also read up here on xda about the general rooting unlocking thing a bit more so you get the overall process a bit better perhaps next time.
About windows. There are so many tools out there to help ya with disabling some of it's spying, turning off smartscreen, auto - uploads of all your data to M$oft, etc etc.
It's not hard to find.

Thanks for the response - I think I've worked out what is going on.
Typing ADB devices, my PC recognises the phone until I put it into fastboot mode - typing adb devices when in fastboot comes back with nothing and therefore when I try to flash, I assume the devices aren't talking to each other.
Not sure if there's a work around or whether it's a case of finding a new PC to try it on?
Thanks again.

try another USB port first; use USB 2.0 if available! Reinstall google ADB drivers, make sure to use latest!
If above will not help:
on your computer: open device manager; on your phone: put your phone into fastboot; connect your phone to the computer WHILE keeping an eye on device manager; as soon as you'll connect your phone new device will appear in device manager ("unknown device" most likely but it might be some "android device" or "ADB device" too); right click it —> update driver —> automatic driver update worked in most cases for me, if not, go manual way and select google's "android fastboot device" (or something like that, can't remember actual name of the device); after driver install confirmation you should be good to go

This is brilliant - thanks for all the advice. Having this support is helping me gain the confidence to learn more, research more, and then give it a go.
All the best.

thats if I am not wrongly remembering my experience:
because now your phone is in fastboot mode thus it won't show up with that command anymore.
Try: 'fastboot devices'
I imagine you put it into fastboot through: 'reboot fastboot' when you where in adb?
When in fastboot you can go on and flash the recovery and such.
Are you still in need of help here?

Hey, thanks for the clarification - been away and so haven't implemented all suggestions, yet.
I typed "adb reboot booloader" which I assumed put it into fastboot mode and then unlocked it using "fastboot flashing unlock".
I tried fastboot devices but the PC still doesn't see the phone. I'm going to try the update usb driver suggested by Tamsta_T and see how it goes.
Thanks for your help.
