Hello,
i'm trying to access the bootloader in my wildfire, i'm keeping pushed the return button during the boot but nothing happens, and it just goes with the normal booting process. am i doing something wrong ?
the phone is not rooted and it is updated to the latest OTA.
Thanks in advance.
return button during boot? . im pretty sure your device has to be off, then you hold down the trackpad and press power button and it boots into bootloader.
guys i did oem unlock and when i reboot its just stuck on the nexus logo. whats going on? i am using a mac. i flashed the stock image and it was back to stock but whenever i do oem unlock and reboot it does not boot its stuck at the logo

Try this, had the same problem yesterday:
If you get stuck in a bootloop rebooting the tablet after unlocking the bootloader...
Here's what you do..
1) During the bootloop.. hold the power button + volume up + volume down button simultaneously to get yourself back into fastboot mode as you were previously.
2) In fastboot mode.. use the volume keys to scroll to Recovery and the power button to select it.
3) In Recovery (Android robot on his back with a red triangle)... tap the volume up button and the power button simultaneously which will bring you into stock recovery. Again.. Don't hold the buttons, just tap them simultaneously. Also make sure you're holding the correct volume button. Up will be the volume key on the right.
4) Once you're in Recovery.. perform a factory reset/data wipe and then reboot your tablet... you should now be back to the Welcome Screen.

Exactly what I did to solve the bootloop after unlock. Worked with no problems after factory reset/data wipe. Just went back to the 4.2.1 I had on it.
With my Nexus 7, when unlocking the bootloader, it would automatically factory reset itself. The Nexus 10 doesn't appear to do this, but it does appear to be a required step regardless (I guess unlocking the bootloader does something that is only fixable with factory reset, for security reasons).
So as mentioned already, a factory reset should take care of things
thanks for the tip.i got something like that，i unlocked rooted the tablet and all was ok untill i went into system settings to update it via ota. after the ota had been downloaded succesfully it rebooted into recovery automatically but failed to update. then i couldnt get into the system any longer even after i flashed factory image using the toolkit in another thread.
i will try this when i get home，hope it can solve my problem too.
edit：done. thanks again for the tip

here is the think, I unlocked nexus 10 oem lock then flashed with fastboot and original framware that google suggested for this tablet in fast boot everything goes right but stuck in logo x boot"I also tried 5.1 firmware "tablet reseted then i put the tablet to oem lock again but still same problem again i went to bootloader and again in recovery mode i chose Wipe and factory reset but still same problem. i put the power button 10s but no solution, any idea?
Does anyone know a way I can unlock the bootloader or unroot the phone without using the power button?
I can get into android recovery but cant select any of the options because I have no power button.
I managed to get into fastboot with the Toolkit and I was trying to get my phone back to stock to warranty it. I wasn't thinking and re-locked the bootloader before unrooting the phone. Now I can't "undo" that because of the phone prompts to choose yes or no when unlocking the bootloader.
I am looking for a way to unroot a phone with a locked bootloader or a way to unlock the bootloader while bypassing the yes/no screen.
I found a solution but it was for the galaxy nexus using a hex editor and I wasn't going to mess with that unless it was specifically for the nexus 4.
Any help is appreciated.
I recently got the update for 4.4 notification, clicked it but then the installation froze on a picture of android with an exclamation in his belly.
After that I could no longer boot to bootloader or recovery.
I tried fastboot but I cant not install the drivers as I cant boot to bootloader.
So I tried NRT and managed to get my recovery back (TWRP), but still no bootloader.
I have the option to return to stock on NRT but I am afraid it will fail and brick my N7.
I have SuperSU, flashify and TWRP apps running now with TWRP recovery also bootable.
How can I get my bootloader back?

Hi, Siddy1200...
If you had no bootloader... nothing would work... at all.
The bootloader underpins everything you do with your Nexus 7. Nothing happens without one... in which case , you'd be effectively HARDBRICKED.
The fact that stuff is working indicates that your bootloader is fine.
To access the bootloader manually... shut down the Nexus 7 completely.
Press and hold the VOL DOWN button...
Whilst holding, press the POWER ON button, for around 5-10 seconds...
You should now boot into the bootloader.
This key press sequence should also work if you CAN'T shut down the Nexus 7 normally... for example, if you're bootlooping. I've had a few scary moments myself in the past, and the VOL DOWN+hold, POWER ON sequence has always thrown me back into the bootloader...
Rgrds,
Ged.

Thanks for the reply Greg.
I can't boot to boot loader, that means when I power on with vol- pressed, then select boot loader and press power , it doesn't work. The screen flashes for a second and it is back to the previous screen to where I can choose restart, recovery, boot loader,etc.
This also happened with recovery but I fixed it, now I'm trying to fix the bootloader

Apologies, Siddy1200... but I'm a little confused... based upon my reading of your post... I think you're already in the bootloader!!.
"...it is back to the previous screen to where I can choose restart, recovery, boot loader,etc..."
The bootloader features a green android, lying on its back, with it's belly open - some really tiny text at the lower left hand side of the screen giving details about the current bootloader version and it's lock state. At the upper right hand side of the screen, adjacent to the power button, are selectable options via the POWER BUTTON, which can be cycled through with the VOL BUTTONS... and these options are START, RESTART BOOTLOADER, RECOVERY MODE, POWER OFF... and then START again.
Somewhat similar to your above quoted description.
Selecting RESTART BOOTLOADER will just bring you back to where you already are... ie., the BOOTLOADER.
Also, if you can't access the bootloader, how are you managing to boot into TWRP?... as this is normally done via the bootloader... ie, by selecting the RECOVERY MODE option.

Thanks for your persistence Greg, I think I was confused as what the bootloader actually is, now I can see I am already in bootloader :silly:
I will return to stock with NRT and try the 4.4 update now.
Is there any way to unlock the bootloader without the volume buttons? Mine have broken (even when the button circuit board has been replaced) and all programs or guides i have found ask you to do at least one action with the volume buttons.
Unfortunately i have also upgraded to 5.1.1 so no easy root options.
Stock rom (hence the need to unlock and add functionality due to the loss of hardware buttons)
Thanks!
I think you should be able to use abd and use a command that goes something like "adb reboot bootloader" which will allow you to get in to the bootloader and unlock it.

You should also be able to reboot to Bootloader from NRT, can't you?
You'll be able to adb reboot bootloader but as far as I remember you'll have to confirm unlocking a bootloader using volume keys.
Just checked, if you have ADB debugging on, you can just use NRT to boot you into the bootloader from a regular state. No need to use button combos, however, I think you need to be able to use the volume rocker to confirm the unlock......
