[Q] Can Not Get Into Recovery

I am unable to get into recovery of any type on my Xoom. When I try to get into recovery I get the Android with an exclamation point. I've tried factory reset; I've followed instructions for CWM recovery, etc. I just can't get past the damn Android with the exclamation point (inside a yellow triangle). Can anyone help?
BTW, there are no programs or data on the internal storage of the Xoom.
Use ADB to unlock your device again and push the recovery image again. Then try to boot into recovery.
Ok, I unlocked the Xoom and it rebooted. After the Xoom rebooted, I ran adb reboot bootloader and the Xoom went into fastboot. Now what command do I use to push the recovery image? From the platform-tools directory if tried: "adb fastboot push recovery recovery.img and nothing happened." I then tried "adb fastboot flash recovery recovery.img" without success. Help!

Assuming your in the directory with the recovery.img as well:
Code:
fastboot flash recovery recovery.img
(no adb, no push)
Do the following plz with this recovery image. I assume you already have android sdk installed and adb on your laptop.
To download:
• Recovery Image: http://goo.im/devs/teameos/recoveries/wingray/eos-recovery-r6.img
Steps:
1. Power off your XOOM device.
2. Press and hold the volume down button while pressing the power button at the same time. Note: Even if your xoom starts again, just keep the button pressed until you see "Starting fastboot protocol" on the screen.
3. Connect Xoom to your computer via USB.
4. Open a ‘Command Prompt’ or ‘Terminal’ window on your computer in your sdk/tools folder.
5. unlock your xoom and flash the recovery image. The recovery image should be in your current working directory where you have command line navigated to: Type:
adb reboot bootloader
fastboot oem unlock
fastboot flash recovery eos-recovery-r6.img
fastboot reboot adb reboot recovery
Now, you have your device unlocked and recovery installed. I prefer this recovery than others. Give it a try.

Thanks, that worked and I'm back in operation with the Xoom. I really appreciate the support this forum provides.
I am happy I could help, and happier you are back to xoom operations without issues
Unlock, reboot and issue resolved!!! Cheers

Recovery boot loop which runs OpenRecoveryScript that then reboots device

Hello,
I'm trying to recover from a bad flash that left my tf101 in a scripted recovery boot loop. Trying to start the device results in the tablet booting to recovery and then running an OpenRecoveryScript which formats cache and wipes data w/o wiping /data/media and then reboots. This reboot cycle continues as it doesn't reboot to system but to recovery again and repeats itself. I'm unable to get into APX mode. I am able to see the device with ADB when it's in TWRP recovery (v2.8.1.1) for a short time and run commands from there before it reboots. The commands I've tried are "dd if=/sdcard/signed_twrp-2.8.1.1_tf101.zip of=/dev/block/mmcblk0p4" and "echo boot | dd of=/dev/block/mmcblk0p3 bs=1 seek=0" neither of which have helped. Does anyone know the command to clear this OpenRecoveryScript from memory and get me out of this boot loop?
Thanks!

Help! Bricked Phone!!!

I have a phone, it is bricked and it doesn't go past the logo. I tried using adb wait-for-device but it doesn't work. It won't boot into the recovery mode and it is a tecno bd4... I can't turn it off as well, The OEM is unlocked and i tried flashing magisk.
What i did:
-adb devices
-adb reboot bootloader
-fastboot oem unlock
-fastboot flash boot boot_patched.img
-fastboot reboot
Any kind of help will be appreciated
Edit: I have also tried using adb wait-for-device
and also tried to use the ondemand script but my phone won't go past the logo
Does your fastboot mode still show? (usually Volume Down + Power)
Reflash device's Stock ROM to get rid off of all modifications you applied so far.
