My tab is already unlocked by default... did you buy it from a carrier?

[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

If you are stuck in bootloop you won't be able to enter bootloader directly by pushing Powe+VolDown.
Firstly you have to power off the device (Power+VolUp+VolDown) and, when the screen goes off, you will be able to enter bootloader again (VolDown+Power)
I hope it helps,

Can you detect your phone via adb ?
--> adb devices
if the answer is yes, you can just type
--> adb reboot recovery (I hope that you have twrp because that's a touch recovery)

anyway thanks for your help, now im on my way to check it out how much will cost repair the button...

Help unlocking/rooting Lenovo Vibe C2 K10a40

So guys, the thing is: I haven't found a way to root nor to unlock the bootloader in this phone.
Focusing on the bootloader, there is an option in the Developer options which says "OEM unlocking", that supposedly allows the bootloader to be unlocked. Plugging the phone on the pc USB and using adb to get into fastboot works fine, but after typing "fastboot flashing unlock" the command prompt keeps on waiting with "..." for the next phone's action, that's where the problem begins: on the cellphone screen, right after the warnings about the consequences of unlocking the bootloader, appears: "Press the Volume UP/Down buttons to select Yes or No." If Volume_Down is pressed, it returns to fastboot, but if Volume_UP is pressed nothing happens, literally nothing, Power button also does nothing, the only one who works is Volume_Down, making it unable to unlock the bootloader via this method.
I tried to use "adb shell input keyevent 24" (knowing it wouldn't work) to try to send the Volume_Up command from the pc.
So I wanna know if there is a way that, through that fastboot waiting instance (the three dots "..."), I can send the Volume_Up command from the pc, enabling the Bootloader to be unlocked, making the root easy or even possible.
Thanks in advance!

Just because you have the "OEM unlock" option in settings doesn't necessarily mean you can unlock bootloader, the manufacturer or your carrier may have disabled that option in fastboot. Not all devices can be unlocked.

Google isn't the the one that has control of that, that's controlled by the device manufacturers and/or each mobile carrier. In this case, it's controlled by Lenovo
The only devices that Google has control over whether they're rootable or not is only the Nexus and Pixel devices, not any of the others.

I think it is saying that the connection between PC and your device was interrupted for some reason. I was probably a problem with your cable being loose and losing connection where it plugs into your device.
It is not very likely but it could also be an unstable electrical supply grid in your area, the power in the building where you are could have dropped momentarily, I doubt this was the cause though, but it is one possibility.
Use a different cable or find a way to make sure it connects and stays connected, then try flashing again.
The error you have is described in the attachment below, it explains how to solve.
For future reference, the link below has a list of all flash tool errors and how to solve them.

You can access the recovery for this model after you send the command (ADB and fastboot commands): "Adb reboot recovery" where "Adb reboot boot loader" and then you have to click on the volume up and the power button at the same time and its success

TWRP for your device probably doesn't exist, you'll have to wait for someone to be interested in building TWRP for your model (not likely to happen if it hasn't already) or you can port or build your own TWRP.

Forget about ADB, you need Fastboot access. While in the bootloader interface, connect your phone, look for it in the Device Manager and change its driver to Android Bootloader Interface, or something of the sort. Next try "fastboot devices" on the command line, see if it detects your device.
I brought my phone to repair shop and they detected that the hard disk was dead.
Just bought another Pixel 2 to have more awesome photos
You have no fastboot I guess.
Boot into fastboot, plug in the usb cable and press and hold the volume down button for like 15 seconds, and then it will be recognized by the PC. You can flash back the stock rom after that.
Hey I had the same problem. Just stuck in bootloader mode. In my case, the boot slot changed itself from b to a (access denied, same as your problem). What I did:
1. I boot my phone, then it'll be in bootloader mode (same as the first picture when it says 'operation denied')
2. I kept pressing the power button, then my phone boot into bootloader again (bootloop). I kept holding my power button until my phone boot into right boot slot. (It took me 10 bootloop to boot into right boot slot, I just keep holding my power button when in the bootloader mode)
You can add my telegram : (@)Djkuns if you're confused. Hope I can help! Goodluck!

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.
