[Q] Frozen at bootloader, no adb or fastboot

Hello,
I was attempting to clean out (format) everything on my phone and start over with a fresh ROM, and it looks like I went a bit overboard. Now I'm stuck at the bootloader, but it appears to be frozen. When it loads, I get:
Code:
FASTBOOT MODE - NO BOOT OR RECOVERY IMG
PRODUCT NAME - HERRING
HW VERSION - REV 11
BOOTLOADER VERSION - 19020XXLC2
BASEBAND VERSION - 19020XXKI1
CARRIER INFO - TMB
SERIAL NUMBER - (REDACTED)
LOCK STATE - UNLOCKED
The menu appears as well, but I am unable to change the current selection, or perform a selection. (My power button stopped functioning a couple months ago).
Occasionally when I unplug the usb cable I'll see a quick message "USB Control Init USB Control Init End" and it restarts the bootloader. FASTBOOT MODE then just appears empty, and I still cannot access the menu items.
ADB was working before, but now 2 separate computers cannot detect it using "adb devices". I hadn't tried 'fastboot devices' beforehand, but it doesn't detect the phone now.
I tried installing a couple different drivers (Google's, PDANet), and using Wugfresh NRT, but could never connect.
So how's it look, doc? Will it live? Or should I bury it?
Thanks!

As long as the bootloader isn't deleted there's a good chance.
I think you have deleted the OS and the recovery :silly:
When you are in the bootloader, only fastboot commands work.
Type "fastboot devices" to check the connection
Or "fastboot help"

I had to force the "Google Nexus BootLoader Interface" driver onto the system (win 8.1)
I know it says Acer, but it is my Nexus S

When fastboot.exe can see your device you can flash a recovery image.
"fastboot flash recovery recovery.img"
"fastboot boot recovery.img"
You should now be able to start the recovery and use the adb commands.
Hope some of this can help

Thanks for the response! I wasn't sure if I would even get a reply, as the board appears to be rather quiet.

Yeah, I'm afraid I did. I got a little overly aggressive in my data purge

Sadly, therein lies my problem. I haven't been able to get fastboot to recognize my device, at all

I tried the driver install listed, and I assume it successfuly installed, though I'm not sure how I'd check. but I'm still having the same problem. neither fastboot nor adb recognize the device (though as you said, adb wouldn't at this stage either way).
It doesn't appear that it's even showing up in the device manager (using Windows 7 x64). No search for drivers, no unrecognized device, nothing
I'm afraid it means that my phone is actually freezing during the bootloader loading, since the computer does not appear to recognize it and I can't navigate its menu.
Is there anything I'm forgetting? I may try booting into a Linux live image, to see if windows is just ignoring due to some driver issue. Will follow up with those results.
Thanks again!

I suggest removing all drivers. Each and every trace of it to be removed. Then install the Google USB drivers.
You can also get drivers from Windows Update...

Volume down button broken, so there is no fastboot

Hi, my volume down button is broken, and I'm just wondering if there are any way to get into fastboot without hardware buttons... I was flashing through fastboot and I made some mistakes in the process, so basicly I have no S. O.
When I turn on the phone, it goes straight to recovery mode, but I'm not able to choose any other option, because my volume button is broken
Is there any solution or workaround to get into fastboot? Is to hard to repair the volume buttons? Thanks in advance...

TWRP custom recovery has a Reboot option, which includes 'Reboot to Bootloader.'

Setup a PC / Laptop for ADB. There is a command: adb reboot-bootloader
If ADB in recovery mode does not work with Windows, use Linux (an Ubuntu Live CD is enough) - install fastboot and use the command: sudo adb reboot-bootloader

Recovery mode adb should be working - even with stock recovery.

I see. Can you use volume up to highlight adb? Then power button to enable?

Nope, I can't scroll up neither down, and "volume up" does nothing... My father has another moto g; if I borrow his volume rocker, could I be able to replace it and get into fastboot?

Possibly, but without a working volume rocker I see no way out of your situation.

Need Help, tablet in boot loop with Asus logo after flashing stock. Can't access fastboot.

Hello,
I was given this TF300T to check if I can fix it (it was really bad soft brick with data partition not being mounted by TWRP and giving on boot that it is encrypted).
I tried flashing stock and after stock ROM was flashed (followed the guide I found here) rebooted as per the guide.
Since then the tablet is in a boot loop, I can't turn in off completely and upon trying to restart it while holding volume down I still get into the boot loop. With volume up, it vibrates one and then "connects" to my computer as an unknown device.
If anyone has any idea on how to fix it, please respond. All help is welcomed.
Video of Boot Loop

if if vibrates, it's not a TF300T... because the TF300 doesn't have vibration...

Well, based on the kernel, and what it did say in the TWRP recovery before I tried flashing stock it is TF300T. And after checking online, the model for Bulgaria does have a vibration motor.
How the question is how can I force it to boot into fastboot mode.

Before the bootloop starts again hold "Volume" down and you will get into fastboot mode.
After that you may do a Buster99: (1) Unrecoverable bootloader error but not Bricked! | XDA Developers Forums (xda-developers.com)
BTW, if you cannot get into fastboot mode, please, dowload "Minimal ADB and Fastboot" and try ADB.

So I tried that, but it still doesn't get me into fastboot mode. I also tried it with the reset switch and it still gets into the bootloop and nothing connects to the pc. However is I hold the volume up button, the display goes black and it does connect, but my pc doesn't recognize the device and can't find drivers. When I do the volume up it connects as an "APX Device"

In this mode it is still not seen either from ADB or Fastboot (tied both with Google Platform Tools ADB and Fastboot and with minimal ADB and Fastboot).

Seems there is a driver problem. Hopefully you will get it. So you may try the attached driver.

That was helpful, the tablet is now connected in APX mode. I tried finding the NVFlash tool for the TF300T, but it is dead and APX mode itself doesn't let you use adb or fastboot commands

Asus Zenfone 5 Lite ZC600KL stuck on logo

Hello all
need some help with the mentioned phone that is stuck on the Asus logo when powering up
i have tried to go into the recovery / reset mode but for some unknown reason all i can seem to get is CSC fastboot mode long press power key to shutdown and nothing else even using up and down volume nothig
i tried using tools like minimul ADB as well as fastboot platform tools now with ADB minimul phone did respond to it once but after nothing else..... the fastboot platform tools does respond and when using the command fastboot devices it will show up what appears to be a serial number another command fastboot recovery i believe will make the phone shutdown and reboot back into fastboot mode this time with what apeears to be a barcode on the right side of the screen
now i have a sneaky feeling that the phone has somehow corrupted the boot partition or where ever the boot files are located preventing me to boot phone or even get into recovery for a factory reset
now as mentioned above my phone is communicating with the computer so tho i am assuming only the platform tools will work with fastboot commands but adb wont work properly due to debugging mode not enabled
does anyone have any solutions and detailed instructions on how to fix the problem without firmware flashing
i will happily flash the firmware as a last resort but would need some advice on software to do this as i am used to MTK chipsets and using SP flashtools but this model phone isnt MTK
i tried
fastboot reboot recovery
but don't work
any help would be appreciated
many thanks

fastboot reboot recovery is not a valid command, so it's same like fastboot reboot
not sure what is the problem with that phone. maybe it's just end of life/emmc wear-out.
you can try fastboot continue that would boot into android ignoring volume key in case button stucks/short-circuited/wet.
if that doesn't help you can post the output of
Code:
fastboot oem device-info
fastboot flashing get_unlock_ability
flashing is possible from EDL mode, but that won't fix hardware issues:
Bootloop issue and can't go to recovery mode

Unlock OEM and flash bootloader

Hello,
I have a problem with my mobile, I cant access into the phone and I want to flash a new ROM and also flash TWRP. I have a few problem which really don't allowed me do something.
+ I don't have an access to phone to set USB debugging or something else.
+ I cant flash a new TWRP through ODIN 3, because there is OEM lock.
+ I cant use Samsung Smart Switch and "Emergency software recovery" method, because "This model does not support firmware upgrades and initialization".
+ I cant flash stock firmware because ODIN 3 stuck in a half of process (in part "SUPER" when is flashing).
+ I cant use SP Flash Tool because there appears "Please select one ROM at least before execution." and I don't have an scatter file for Exynos 9 9810 which is inside N770F.
+ I cant use ADB and fastboot because, when I try to type "adb reboot fastboot", the phone approach restart, type "Entering fastboot" and nothing else, stop and stuck it on this text, and nothing happened.
Could you please help with this problem. I don't care about stock or custom firmware if will be flash to phone.
Thank you so much.

You should use Odin, at least version 3.14.4.
Restart to fastboot on this model:
Code:
adb reboot bootloader

NO I Cant as I already wrote, when I try reboot to bootloader phone stuck in "Entering fastboot" and nothing happened next....

What do you think should be happening? Because I do not know.
Exactly Entering fastboot... means that you are in fastboot mode, which you can check by executing the command fastboot devices.
Exit this mode by long pressing [Vol -] + [Power]

I saw some threads that it is not right, and also I thought that when I type command "fastboot devices" also nothing happened means appears "waiting for any device" but nothing else. So what can I do after it for flashing please?

Do you own an original or refurbished phone?
You can check this in the Phone INFO app, available at apkmirrors.
