Lenovo tab 2 A10-70 Boot looped , Unable to get into bootloader or recovery - Android General

*accidently put this in the wrong thread, if a mod could move it. thanks*
So I wanted to get rid of the chinese recovery that was on my lenova tablet and messed up along the way.
I first enabled debbuging USB on my tablet and used adb on my pc to boot my tablet into fastboot (I am unable to enter fastboot any other way).
I ran this line: "fastboot oem unlock" and then "fastboot flash recovery twrp.zip".
The TWRP version i flashed onto the recovery was a wrong version causing my tablet to go into a bootloop on restart.
I get no response from vol up+power, vol down + power, vol up+vol down+power.
I had to let my tablet battery run out since the back battery is unremovable.
The tablet shows the splash screen when it boots and restarts after about 5 seconds.
I have no idea on what to do so i turn for help here

[Q] Really Screwed Now....I Think

OK, after flashing the CWM through fastboot, which seemed to work fine, now once I reboot, it still endless cycles on the moto logo, and if I try to UP+Power, all it shows is Starting RSD mode 3, and I can't do anything. Can't boot with DOWN+Power either.....
If I try to adb reboot bootloader, I get a error: device not found message.
Is there any hope, or do I now have a Motorola Xoom Door Jam.......
HELP!!!!!!!!!!!!! PLEASE!!!!

Lol, calm down. If you can get to the logo screen, then you are not bricked. Sent u a pm. Your system is looking for a boot image.
While in "RSD Mode 3"
Code:
fastboot flash boot boot.img
Yes the Xoom is not responsive, but , press Vol Down + power until the screen goes black. Then quickly press and hold Vol Up + power. The Xoom then will go into the bootloader (fastboot), wait for the command from fastboot, then flash the boot.img. (the above command)
After flashing the boot.img do (the command below)
Code:
fastboot reboot
It should boot up.

[Q] Stuck on fastboot with broken pwr button

Hi I have the following problem: after I flash Cannibal open touch recovery I could not flash any .zip file so I decided that I go back to CWM touch so I restarted my phone. Phone booted into fastboot mode with the following message no boot or recovery IMG so I decided to flash recovery with fastboot. I opened the folder with fastboot command flash_recovery connect the phone to usb but the command line always showed waiting for device. I unplugged the phone and tried to press the volume keys but nothing happened as if it freezes. I pulled the battery and try it again but no response. I cant connect phone to odin because it has broken power button and after I insert the battery it always turn on itself. Please advise me what to do thank you.
Seems your drivers have gone corrupt. Try a different system and use Nexus Root Toolkit.
I tried this option but without success. Phone does not respond to anything. No volume up or volume down. It´s just stucked on bootloader.
This link says that if you get <waiting for device> , then fastboot is not configured properly. Check out the link over here.
You may also try this command "fastboot boot recovery-clockwork-6.0.4.3-crespo.img" to boot into recovery without installing it.
no hope
The reason you cannot navigate in fastboot/bootloader is that your powerswitch is probably stuck in the "on position"...does your device immediately power on when battery is inserted?
The way i solved this a few months ago was to completly remove my powerswitch from the board power my device on..use quickboot to enter fastboot menu and input commands...
Also completely removing your power button makes powering on your nexus alot more complicated.
what i did was go to download mode (holding vol+ and -) and pluging phone in..this takes you to download mode
then you need to get a copy of a boatloader file to flash via odin which will reset your phone and power it on...pm me if interested i can provide you with files necessary

OPO can't access fastboot mode

Hi,
I have a problem with my One Plus One. When I open the phone, there is only the "CYANOGEN RECOVERY" screen that appears.
I can access sideloading using the menu but it is not working. I tried to sideload CM12 and it is looping back to the recovery screen
More over, I cannot access fastboot mode. I tried to use adb to reboot the phone in fastboot mode but adb only sees the phone in sideload mode
The Power + vol up combinaison doesn't work...it will come back to the recovery screen
Any idea ?

Are you attempting to boot into fastboot with the cable connected? That's been known to cause issues, so unplug and try again.

Htc one a9 can't boot no usb debugging

I really screwed up this time...
I did a factory reset on my phone, which means that the settings are back to default and I don't have USB debugging. Me being careless, I was in download mode and while trying to setup TWRP I typed:
"fastboot flash boot twrp-3.0.0-3-hiae.img"
instead of
"fastboot flash recovery twrp-3.0.0-3-hiae.img"
Now whenever I boot it takes me to my recovery and I can't change the boot image because USB debugging is disabled. I hope my htc isn't done because of my carelessness.
what happens when you tell twrp to reboot to recovery or download mode? I'm guessing that those are still factory, if so, fastboot commands might work in one of those, if you can get into one, to reflash boot.
Recovery mode shows a phone icon, then you need to press and hold power button and tap vol up to go fully into recovery mode.

Phone stuck at fastboot mode

Hello, everyone I have an Ulefone note 8 dual sim which after some time of use suddenly showed up dm-verity corruption at start up. I searched through google and decided to flash the rom again with sp flash t ools (Ulefone official rom)
So everything went smoothly, but after i started up the phone, it's stuck at fastboot mode. Here's a photo
The problem is, I can't exit fastboot I tried pressing just the power button and power button and volume up/down and the result is the same.
Can anyone help me?
bro you can exit fastboot from your pc by cmd "fastboot reboot"
or click all button for 30-60 sec or remove battery plug
