HELP! I bricked my RK3188 Pumpkin.. - MTCB Android Head Units Q&A

I loaded a ROM and now the unit cannot get past the ANDROID logo at start up...
So I attempted to load the factory ROM, but the unit won't now go into recovery mode, it just has a black screen...

While at the Android logo, did you push the reset button and waited for the system to correct itself? This will
happen when you load a fuse-prom the first time.

I have tried both the "RST" button push at the Android logo, and the smaller button that is not labelled. How long do you think it should take? Neither button seems to return the HU to normal, it just sits there at boot logo.
The recovery mode no longer works either, so it appears I am totally stuck!
Thank you for your help so far. Will go and try it again.

OK. Just tried a quick push of the reset button and it did nothing. Retried with a long push and it turned off the screen but nothing else happened. A push of the "RST" button just cycles the unit and it sits at the boot logo again.

Press reset button and power button together
After about 5 secs release reset button, but keep pressing power button
When booting screen appears release power button.
It boots into recovery.

Marius, thanks for the reply. My unit has no hard buttons, so this method won't work for me. I already got the unit into recovery mode ot apply the ROM, but after the unit rebooted the recovery screen is no longer working, it is just black with a few vertical bars displayed top left...
It is truly annoying.

I tried everything but nothing even logo you see

My unit is on its way back to Amazon. Nothing worked at all and I tried every recovery method on here.

Phone won't boot up

I flashed Hard SPL 1.34 then upgraded the radio to 25.05 then put on Bepe's 0.95 ROM
It worked for a while, then started to crash and needed to press the reset button to boot it up.
Now it won't move from the Touch Diamond startup screen when I boot it up, then turns off. Can't hard reset, and can't enter bootloader.
Any ideas? I just suddenly did this, also, it doesn't have the original vendor ROM on it so if I send it back, what's the chances of them getting into it and then saying a big FO because I messed with it?

What happens when you try to enter bootloader mode? Have you tried removing the battery for a while?
bootloader is volume down and reset yes?

Yes, korrect
diddly squat, not even any ROM id's coming up on boot screen. I think it's bricked
Hard reset is volume down + enter (round key) and red reset button. Keep down the first two until you see the reset screen

Can you be a little more descriptive? What exactly happens? Does the phone reset at all?
Did you hold volume down for a few seconds? Just pressing it while you hit the reset button is not enough. You need to hold it down until the tri-color bootloader appears. That's usually around 5 seconds.
Edit:
Clarification: You press volume down and hold it. Then you shortly push down the reset button with the stylus, while still holding the volume down button. You can release the volume down button after the tri-color screen appears. (or after 10 seconds if it's really not coming up)
Should it come up, you can use the chance to flash another ROM. If that's giving you trouble, see the link in my signature.
Ok, here's what happens
If I press the power button, it vibrates, Touch Diamond comes up, no ROM info, stays for a few seconds, disappears, phone is then off again.
Holding volume down, pressing reset button, nothing happens, phone doesn't power on, volume down held for 10 seconds, nothing happens
Holding volume down and action button, then pressing reset button, again nothing happens at all.
I successfully hard resetted the phone with the official ROM, but since installing Bepe's 0.95 I hadn't attempted a hard reset, but I had rebooted the phone successfully before this problem occured
Okay, in the off state the reset button will not function.
What you could try is turning it on and immediately afterwards follow the bootloder-procedure.
Also I did a quick search. The following threads might or might not be related and help you (I didn't read them, too late for me tonight):

I realize they're for different phones, but that might not make such a big difference in this case...
also, can you confirm that you successfully flashed hard-spl before this? as in, you manually went to bootloader and saw that it had changed to hard spl?
Try this....
might seem stupid but your phone is also acting as it would with a 99% flat battery........phone just starts then dies.......
Stupid question......put it on charge for a couple hours...you never know....it might be the problem you have
Well I came to start it up this morning after leaving it on a shelf all night with distain and it booted up fine.
So I'm going to flash the official ROM, and other stuff back to factory and send it back. there's obviously something wrong with it somewhere.
Thanks for all the help guys, let's hope my next diamond is a bit more well behaved.
phone does not boot up
Hi, i got a prob with my phone, when i power it on it gives me that display with the 4 colors(red,green,blue and white), i have tried hard reset but it does not help, can anyone assist.

[Q] Has anyone encountered a frozen boot screen?

So I messed up...
I flashed the new JB, rooted, and unlocked it(FreeGee) and it was working decently. For some reason (that I can't remember now), I had to go back to ZV7 using LGNPST. When I reupdated to ZVB, I think I forgot to unlock with FreeGee and debloated. (at this point, you're thinking "this guy is a complete idiot") After my next restart, I got the dreaded "security error" bootloop.
I didn't panic yet. I went ahead and tried to downdate to ZV7 again using LGNPST. At 85%, the phone rebooted as normal but after the boot screen, it froze showing the "4GLTE" screen at the end of the animation. I tried waiting it out but no luck.
When I tried downdating again, I'm getting the same boot screen freeze. Worst part is I can't access recovery; the phone just restarts and goes through the boot animation.
So now, I'm panicking. Anyone else encountered this problem and/or can enlighten me please?
Go to recovery and factory reset the phone.

I tried accessing the recovery (Vol up + power?) but it just starts the boot animation. Is there any other way to access it? Also, because I used LGNPST, it should open the stock recovery, right?
Power button 45 seconds
Hold the power button down for about 45 seconds. This will truly turn off the phone.
Access recovery using Vol. Up and Power buttons, then factory reset, and reboot.
You will be good to go.

No luck :crying:
As soon as I hit the two button combo, I get the red LG globe logo pop up for a second.
If I release as soon as I see the logo, it goes to the boot animation
If I continue to hold the buttons (and wait for the the blind menu on the bottom left), the screen remains black and nothing comes on...even after holding the buttons for 45-60 secs.

HOT DIGGGGIITTYYY!
It worked! Thank you so much!
I couldn't get into recovery last night either.
This is the simplest way, methinks (from command prompt with adb.exe in same folder):
adb reboot recovery

[Q] No Power Button recovery mode for factry reset

OK no power button on the motherboard
So I cannot push vol up power and home
Any ideas please and thank you
And my phone wilnot turn on it gets stuck at the logo screen so I cannot install any drivers
How do you turn it on with no power button?
When it first starts to boot, immediately hold home and volume up and it should boot recovery.
tried

OK it just vibrates and stays black and vibrates every few seconds till I'll I let go that it stays black
Try the same but volume down instead. If this works you can odin flash the stock firmware. Sounds like something may have been corrupted.

Bricked

My 7-year old was playing a game on my wife's 3a XL tonight and it shut off. Now it's stuck in a bootloop.
I tried to boot into Recovery, but was greeted with the busted android screen. So I tried to boot into Rescue, with the same result. The bootloader is still locked, so all my attempts to flash factory images or boot into stock boot, I am greeted with the "not allowed" error.
Any ideas how I can recover this, or is it completely bricked?
If your bootloader is still locked you should be able to sideload the stock OTA. I've never heard of not being able to boot to stock recovery either. What method did you use to get there?

When you reach that screen on recovery you hold the power button and tap the vol + button and your options should show up. Just factory reset the device.

I tried to boot to TWRP but couldn't because the bootloader is locked. So I tried using ADB commands to sideload through Rescue, but it only said "error: closed".
Ended up doing a factory reset. (running now)
Haven't seen you in awhile
Well well.... thought i recognized that username. Good to see you again.
Bricked help
I cannot get my phone into fastboot or recovery. It stuck on the white google loading screen loop. I hold the power and volume down and it goes into fastboot but if I release the volume down button to scroll (while holding the power button) it will then go black and go back to the google white loading screen. If I hold down the volume down button and release the power button it will restart back to the fastboot page. If I release both then it will restart and go back to the white google screen. If I do power and volume up it goes to the "andriod no command" sreen then back to the googe white screen. In sum, is my phone recoverable?

When in fastboot, don't hold the power button down to scroll. Is your bootloader locked?

I'm guessing its locked because the phone is completely stock. When I get to fast boot I dont hold down the power button, but if I hit the volume up or down it instantly goes back to the google white screen and starts the loop over.

When on the bootloader screen can you fastboot a full image to the phone?
Said another way, try to download the full Google image.. not the ota... Setup a computer with fastboot and driver's boot the phone into bootloader mode and try to run the flashall.bat

Try-Once in bootloader scroll to recovery and press power button. When you see Android on his side hold power button and press volume up button. You should now be in stock recovery. From there you can adb or factory reset.
Edit- to get to bootloader power off phone then hold power and volume down buttons at the same time.

LG X K500N will not boot

Hello
I've tried everything to get my LG X K500N working again.
I've replaced the battery, replaced the screen (it has badly cracked), but still the same problem.
You plug the phone in, it charges up to 5% or so and then it tries to switch on. But it never gets past the LG logo.
I've tried the reset procedures (holding down the volume and power keys) but nothing has worked.
Any suggestions?
Thanks
Greg

Well, you'd know if it had been rooted, then.
Did you actually make it to the recovery screen or just try?

I've seen a few methods for the lg.
First
Turn off the device completely
Press and hold vol down and power (6-7 seconds)
Release the power button only when the lg logo appears.
Press the power key once
Release vol down once recovery screen is reached.
Second
With phone powered on
Press vol down and power until logo comes up
Once logo appears, release the buttons briefly, then press and hold them down again.
