[Q] Help! Boot Loop with HKC A072D - General Questions and Answers

So I've been googling for quite some while on this tablet, and haven't got any help.
Brand HKC Model A072D
No vol buttons, there is a reset button tho, I have tried to get into recovery with it but, have gotten nowhere. There is no firmware on HKC official site and i can't even get it to read on my pc, so that means no adb . Does anyone know how to flash or reset this? Thanks...

i have the same model like you. and its says Update Android on 8 from 51...and then freeze..somebody help me please!

I have the P776A model dont know if it will work or not and this is geussing you have a home button though
holding the the home button plug in the charger and wait for a android screen to come up it will show a android dude laying on his back with his chest open and a triangle warning symbol when you see that release the home button and press the home and power buttons at the same time and wait like 1 second then release the power button while still holding the home button and wait for the recovery mode to show then release the home button and voila!! you are in. When you are there navigate using the home button and press the power button to select. Hope this helps.

Nope, it won't work, cause i used the wrong rom to flash it, and its like hard bricked, nothing on the screen whatsoever.
The only is, if you hold PWR and connect it to the pc, you hear a "attached device" noise but the installation of the drivers fail. Need help with this tab

(Fixed) HELP!!!! My HOXL' rom is stuck

Hi everybody! Im new here and maybe my english is bad (sorry for that) but i have big problem!
I have HOXL (at&t) with twrp recovery and i flash Cleanrom v preview build BUT i forget to do factory reset before that.Now my phone is stuck on the boot animation and i can't do anything,even i can't connect with usb cable with my computer(led is not lightening)
Can somebody tell me how can i go into the bootloader or anything that can fix this problem?
Just hold the power button until the phone resets. Let off the power button for half a second then press it again and hold it and also hold vol (-) until you get into bootloader. From there select recovery.
Remember, no matter what if your phone is powered on, pressing and holding power WILL reset the phone. Its a hardware feature to simulate a bettery pull.
tnx

[TUT] Turn on phone without power button. [Broken power button] (HARDWARE)

Quick explanation
Ok so i had the bootloop problem with my Infuse , i fixed it by opening my phone and playing with the power button hardware.
I accidently broke the power button , I looked for hours for a way to turn on my phone with out a power button with no success until i found tried this:
TUTORIAL STARTS HERE
1. Enter Download mode by holding both volume rockers and inserting a USB cable while still holding
2. Get to the screen that asks you if continue with Download Mode or not.
3. Remove USB cable and click the 2nd option.
4. Phone will restart and that's how you turn on a phone with no power button.
Hope it helped some people.

I think only Samsung uses "Download Mode". LG probably has Fastboot like most other Android devices (Vol-Dn + Pwr). But you can try it - it won't hurt.
EDIT: Finally got an LG device. It does indeed have Download mode (and no Fastboot...Vol-Dn+Pwr brings me to a scaled back bootloader). Don't know if if asks to continue or not, but Download Mode doesn't hurt the phone unless you are potentially flashing software with it.
iTs working!! on Motorola Razr xt910
Android 2.2 and is working! After the phone turn on I was downloaded the app pwr bottom to volume key! And that is all okkk!
But take care after press (down and up) if you press up Inside tthe download mode this mean select! And on my first time I have take the recovery mode! xD
Good loooook!

Hello mate!!! Thanks for the post but i have problems here. First of all my phone (Galaxy Wonder) goes into download mode by pressing volume down + home btn + power button, so i though instead of the volume rockets i had to press volume down + power button and then usb cable. It worked. Got into download mode!!! Then i remove the cable, wait a few seconds and then press down to cancel and restart. Then it happens that the screen shows a grey battery, then it fades out and back in for twice. Then the phone just turns off. Battery is charged! What could be the problem? (I have to say i just completely removed the power button from the motherboard, but keeping the metal things that were around it still soldered on the motherboards.
Any guess???
Thanks a lot
LG mytouch e739
My mytouch just goes into s/w upgrade and stays there forever.

[Q] HKC recovery mode

The title pretty much says it all, but I bought a HKC P776A tablet, and to say the most support is non existent for this product/brand, I've rooted it myself which was hard to figure out specially the drivers...but what I can't figure out is how to put this device into recovery mode on boot? And if it can I have no idea how you could even navigate it seeing as it only has home and power buttons as physical...Any ideas?

If you install the appropriate CWM Recovery, you can swipe up and down on the screen to change the selection and then swipe left to select or right to go back.

holding the the home button plug in the charger and wait for a android screen to come up it will show a android dude laying on his back with his chest open and a triangle warning symbol when you see that release the home button and press the home and power buttons at the same time and wait like 1 second then release the power button while still holding the home button and wait for the recovery mode to show then release the home button and voila!! you are in. When you are there navigate using the home button and press the power button to select. Hope this helps.

Hard Bricked Samsung Galaxy Note 10.1 GT-N8013 Tablet:Unable to boot to Download Mode

Hello
I currently have a Samsung Galaxy Note 10.1 GT-N8013 Tablet.
Im unable to boot to download mode and go to screen with the green android to access Odin.
I press and hold the power and volume up button at the same time and its warns me to press the Volume Up button in the warning screen but after I press the volume up button, it boots to the Samsung Logo rather than the green android screen for Download Mode.
I believe the tablet hard bricked because it won't boot to the home screen.
I purchased a usb jig for my S4, S5 cell phones but unable to usb jig the GT-N8013 tablet because the charging port is a lot bigger than the usb jig for S4 cell phones.
I would know what have to or purchase in order to access download mode to restore the tablet to stock using Odin.
If the tablet is not able to restore to stock using Odin, what other methods are there?
Please let me know all the solutions to this problem. Thanks.

I'm just asking, I thought pressing power and volume down button together, then volume up button goes to download mode(odin).While pressing power and volume up together goes to recovery.By the way the volume down button is near the power button.

I pressed both buttons (volume up and volume down) with the power button but the green android is still not showing up. All it's doing is going to the Samsung logo and then Samsung logo just sits there.

Don't press both the volume button at the same. Press power and volume down(the one beside the power button) together ,then when the screen goes with a Warning!! (were it ask you to select volume up: continue or volume down: cancel(restart phone) ).Press the volume up button( the one far away from the power button.You're tablet now goes to download mode. Is that the step you do?

Ok mate ! I was trying to post out that you might be doing it wrong on pressing the combinations of buttons. Cause the way you write your post(no offense mate). Sorry mate maybe my English is poor I think I just misunderstood your posts. I'm just trying to help.Anyway goodluck mate hope you fix your tablet.
P.s. I don't work on any large corporations, but I fix my own gadgets as long as there are available resources.

Can't boot into recovery mode

On my SM-P900 I am not able to boot into recovery mode. I'm pretty sure I have at least a couple of times but now it will no longer work. I believe the key combination is "Volume Up" + "Home" + "Power" until the splash screen is visible then let go of the "Power" button. Am I correct? Has anybody else seen this problem with the SM-P900?
Thanks.
Hmmm, I donĀ“t know on your device, but both on my P905 and on my S4 after last firmware update, I noticed that if you continue pressing the three keys the device boots normally.
to boot in recovery, you should release the keys once you see a small blue writing (never investigated what it says) on the top left of the screen (if I well remember the position).
Give it a try and let me know if it works for you too.
@aviator1
Thanks for the tip. I tried your suggestion until my fingers bled without luck. No matter what I tried I never saw any text (blue or otherwise), just the flash screen.
I don't know about the home key, from a complete shut down I use the volume up key. I'll hold volume up first and then hold power until the very instant that the screen gets power and then I'll release power button while still holding volume up.
