I used Recovery-Tools to flash TECNO-P5_130916__recovery_140106-193223.img onto my phone. The process completed and I was prompted to boot into recovery. The reboot did not complete.
I can get into the boot menu (Volume Up + Power), but when I select Recovery mode or Normal mode the phone gets into a boot loop. Fastboot mode woks and I can connect from Windows 7.
The problem in Fastboot is that I cannot flash a ROM since the bootloader is locked (I get the error "Security deny - Err:0x2017").
Is there a tool that can either unlock the bootloader or reset the phone to factory settings so it can boot normally?
I already tried fastboot oem unlock and it just hangs at "..." No "fastboot oem ...." commands work
fastboot devices shows "mt6572v1_phone fastboot"

I tried to root my Motorolo Xoom 3G however after appliying fastboot reboot commend the device stays at the screen where Motorola logo and Dual core technology are.
The device is not responding any commend that I applied via PC.
I am able to enter fastboot protocol.
Here are the commends that I applied.
1 - adb reboot bootloader
2 - fastboot oem unlock
3 - fastboot flash boot boot.img
4 - fastboot reboot
After I applied all these commends , in MsDOS screen there were fihished text.
What should I do to start the device system again?

You can manually reboot by pressing volume up a power and holding until it reboots, then when you see the red dual core screen tap volume down and then volume up. You should be back in 'starting fastboot protocol' again. Make sure you have actually unlocked. Try fastboot oem unlock again and if it gives you instructions on the Xoom screen, follow them all. It should reboot into the os...skip all set-up steps except go into settings /applications/development and make sure debugging is checked. Then reboot back into fastboot and continue with what you are doing.
I unlocked it again however still it stucks at the Dual core screen. Is there any other operation to start the system.
By the way, I am using a Turkish version of Motorola Xoom 3g. I guess it is an important detail.
I have resolved the problem.
I downloaded MZ601_H.6.1-38-11_Retail_Turkey file from motorolo developer web site.
Fastboot flash boot bot.img
Fastboot flash system system.img
Fastboot flash recovery recovery.img
Fastboot flash userdata userdata.img
Fastboot erase cache
applied the above commends.

Great news! It's so good when you can resolve your own problems!
My phone (NExus S with JB) locked me out because of too many patterns. and then since the mobile data/ wi fi was not enabled, i couldnt log in. so i tried to go to the recovery mode and wipe the data. but it is giving me a dead android with a red triangle. what do i do now?
ps: my usb debugging is off.
Please help!
Try flashing custom recovery if your bootloader is oem unlocked.
Download clockworkmod recovery for crespo. Get your phone into fastmode mode and flash the recovery image.
Code:
fastboot flash recovery recovery-clockwork-5.0.2.0-crespo.img
Then select RECOVERY in fastboot menu.
Alternatively, lock bootloader (if already unlocked) then unlock bootloader will wipe all data too.
Code:
fastboot oem lock
fastboot oem unlock
I have unlocked bootloader.
I enabled adb debugging from developer settings.
1. adb reboot bootloader
2. fastboot flash recovery twrp.img (tried all of those: peter's, from twrp website, from link on lineageos official thread)
Up to this point everything works fine
3A. fastboot reboot then hold PWR+VOL_UP
3B. Hold PWR+VOL_UP
And at this step I am seeing fastboot logo plus "Unlocked" label at bottom (while in regular fastboot I don't see Unlocked label)
My best guess that something went wrong while booting into twrp, and it fallbacks to fastboot. However I have no clue how to check what's wrong, where to check any logs etc.
Any help appreciated
My advice would be to flash recovery again and manually reboot into recovery and not using fastboot reboot
If this doesnt work flash rom again via bootloader....Then flash recovery....Do Not use fastboot reboot....
Manually holding buttons go into recovery
So, Iwas using Havoc Os 3.8 on my realme 5i, but I wanted to lock bootloader again, then I entered fastboot mode and locked bootloader, but I stucked in fastboot mode, It looped. Could not enter recovery or system. Only fastboot mode, because bootloader is locked I couldnt flash anything. I tried fastboot flashing unlock command but it did not work.
But solution was very easy, fastboot was not actually fastboot, everytime I power off device and power up there was not fastboot writing and robot icon, just directly fastboot itself. So actually it is fake fastboot, you just need to use volume buttons and select reboot to bootloader option, once device reboot you will see now fastboot- robot icon then fastboot itself, now you can unlock device with "fastboot flashing unlock_critical" command.
First, power off. Then wait for couple of minutes then start fastboot again.
So I'm not able to install a custom recovery. Adb and fastboot commands work. Fastboot boot recovery causes the phone screen to change to the fastboot mode black and white image but just hangs. Fastboot commands still work there. Bootloader is currently unlocked.
