[Q] Can't Access Bootloader - Not Fastboot issue

My sensation recently developed the touchscreen issue. It having previously been s-off/revolutioned/supercid, I thought it best to undo these things before sending it in for warranty. I ran the appropriate TMOUS RUU_***.exe, but now I cannot access the bootloader at all.
The vol down + power on does not work, it just boots normally.
Adb can't access the device (probably because I can't enable usb debugging).
I had previous changed the superCID back to stock, so that should be find, but the secureoem flag (whichever it is) i believe is still unset (or just not to 3).
Any suggestions?
Thanks XDA

Go into Settings -> Power and disable the Fastboot checkbox. That is what is preventing you from getting to HBOOT by holding the Volume Down/Power button. Also Under Settings -> Applications -> Development is the USB debugging checkbox.

Sorry, I should've been more specific. My touchscreen issue is that it's completely unresponsive. So I am unable to change any of the settings.
Is there a rom that would already have usb debugging and/or fastboot off enabled?

most new ones do have usb debug enabled, but not fastboot off...but if you cant access bootloader, how are you gonna flash another one?
EDIT* another alternative is to try something like this http://www.cyrket.com/p/android/org.l6n.remand/
there are several *better* variations of it on the market, you can use your pc mouse to control your fone, must have root tho

Try this:
- Disconnect your phone from USB.
- Plug off the battery and put it again.
- Hold Volume Down and Power button.
If that doesn't work, try flashing RUU again and repeat the above steps.
Good luck

Usb debug is not enable because adb can't access the device.

You are correct in this matter. My lapse was with the ruu's being able to flash the phone without fastboot or adb. Which brings up an important (somewhat off-topic) point...is anybody attempting to determine how the RUU's are able to communicate with the phone without using the adb?

- Disconnect your phone from USB.

This is unsuccessful. I have tried both builds of the RUU for tmo.
Any other suggestions?
Thanks anyways so far guys!

For me pulling the battery was always the way to enter the bootloader... It bypasses the set fastboot option.
As this is not working for you - is the volume down button broken as well?

help on rooting nexus s 4g 2.3.7

I am following the nexus s one click root. ADB starts and the phone reboots to fastboot mode instead of the unlock part. The lock state is still locked. Can anyone help me with this?

Ensure you have usb debugging enabled on your phone
Go to settings - applications - development and check usb debugging
-if your phone is not displayed or it stays on waiting for device for too long then there was an error with the drivers or its not in fastboot
Please look at your phone :
-using Volume up and down please choose the UNLOCK OPTION, HIT POWER to make the selection .
Why is so dific.? just be very careful .

I have followed all of the directions. This is not my first root. Debugging is on. When the phone resets its goes straight to fastboot bootloader and not to the unlock screen. I downloaded the 64 bit driver also. Is there a different way to do it now that it has been updated to 2.3.7?

[Q] Too many pattern attempts... No Recovery menu

hey guys
i have a HTC Sensation that is password locked, but the real problem is that it won't enter recovery mode.
the volume down key is working as i've tested it in a "sos call", the volume up doesn't work when the phone is turned, but that's not important as it's not needed.
is there any other way to get into recovery mode?
also, if i hold the up key with the power switch, it boots up in "safe mode"

did you try to pull out the battery?
if not take it off,put it again
then hold volume down + power button until it shows the bootloader screen

several times sir, even went as far as draining the battery inside the phone completely, trying it with another battery, leaving the battery out of the phone for a whole day...
are there no usb hacks or something like there is with the samsung android phones?

Are you on a stock rom? if you are the you would have to have un-ticked fastboot from the settings to be able to boot into the bootloader...
try to attach the device to a usb port of a laptop and see if the usb debugging symbol shows up in the status bar. if it does you can use the adb command adb reboot recovery to force a jump into the recovery.

can you take a photo of the pattern lock screen
also what do you know about the device? is it eu,uk,us? also what carrier is the device on? is it on ice cream sandwich or gingerbread? you may be able to run a RUU (rom update utility) on the device, updating the firmware and remove the lock that is currently on the device.

So, no bootloader? When you hit vol down + power it should land you in the bootloader screen, where you then select recovery. Have you tried with the cover, SD, and SIM removed from the phone?

you will need to talk to the owner of the phone, without that info your stuffed tbh. with fastboot enabled in the stock rom you cannot boot into bootloader. without the info like what carrier they are on you dont know what ruu to run to reset the device. without usb debugging you cannot use the pc to send commands as far a i am aware :/ assuming you have the correct htc drivers installed connect the device to the pc, open cmd in your adb directory and type in adb reboot bootloader and see if it responds. again without that info you've pretty much had it. you can try to flash ruu's from the pc at random in the hope that you find the correct firmware and cid, but without usb debugging on there is no guarantee that the ruu will even find it.

yeah, tried the adb reboot recovery, no dice. just error, no device connected.
the owner bought it 2nd hand, so he has no clue, i'm just going to return it. pity that htc doesn't have a "usb key" like samsung that forces "download mode" on the android devices

Possible or Not? Factory reset bricked Pixel 2.

I've spent hours searching and cannot find a definite answer to my question. I see others have asked HOW to fix this issue, I just want to know if it is possible.
Is it possible to factory reset my device or not?
Bootloader is NOT UNLOCKED, and I am stuck on bootloader screen.
"Bootlinux Failed: Not started" when trying recovery mode.
"Slot Unbootable: Load Error" when trying to start.
My device is obviously not found under adb devices as it is locked, but does show up in fastboot devices.
My computer does recognize the android device as well.
Is it possible to factory reset my device or not?
Is there any way to flash a custom ROM and get it operational?

I'd say you're out of luck, I've had the slot unbootable error/ authload error and both usually require re flashing the bootloader, radio, boot.img or a full factory image restore via flash-all to restore via an unlocked BL. I haven't seen any other methods available for the walleye with a locked bootloader I can offer either.

Hi! I don't know if could helps, but did you try to sideload full OTA through recovery mode? This should be go with locked BL too, but I am not sure if you have to have enable usb debuging...

Hey Somin,
I haven't fully looked into that option yet, started to give up. But I can't access recovery mode or even get out of bootloader, and usb debugging is not enabled, oem is locked.
If you have any further information or ideas I would be really keen to hear.
Thanks,
Alex

I do appreciate your help, but as I just mentioned, I am stuck in bootloader screen and get errors when trying to access recovery, download, start or any other option. Obviously using the hard reset only brings me to bootloader where I am stuck.
Is this what you're referring to with key combination?

Hi! No Shut down your phone and try "the game" with power button and vol+ btn... I didn't find any tutorial and it is slightly lottery, but you could get directly to recovery mode if you will press this btns in correct way:
- try to hold them for long time
- try to hold power btn and quick pushing vol+
If you will get to "no command" screen, press again pwr+vol up and you should be in recovery mode. Good luck

Interesting, I get the same error message as I do when I try to enter Download Mode. So this is different than the power and volume down, and different than just restarting it.
So far I just keep getting back to bootloader screen saying operation denied. But might keep trying it here and there haha.
Thanks for your help.

I had the same problem. I was able to solve it by selecting the download mode in the bootloader. There was an error message. Then I fastboot flashing unlock on the console. Then the bootloader is unlocked. No idea why this worked.
Maybe this will help someone who encountered the same problem.

Unlocking the bootloader on Samsung devices works differently from many others. This is a summary of the steps needed:
Enable Developer Options
Enable OEM Unlocking (if not available or grayed out, ensure device is connected to Internet; if this remains unavailable, unlocking is not possible)
Turn device off and boot to download mode
While in download mode, hold Volume + to get to the bootloader unlock screen
However....Not every Samsung device is bootloader unlockable, especially not in the US. Almost all Qualcomm powered devices are locked, and some Exynos devices as well.

Ah. No, you have to power your device off completely. Then, hold both Volume buttons (without pressing Power) and plug in the USB cable from your computer. The device should start in download mode. Then, hold Volume Up until you get the bootloader unlock screen.
