I have a smartphone WIKO GOA on Android 4.4. I use apps or go to Internet. My smartphone is blocked on a black screen with WIKO GOA logo's.
The buttons and the touchs doesn't works. The smartphone is not detected on computer. I tried Factory Reset, Reboot System. The screen still displays No Command message on a black screen. My smartphone doesn't reacts.
Is is a problem with Android software? Is there anyway to repair?

Hi guys,
I have an Aoson M30 (rockchip 3066) and it now won't boot to the home screen.
It Just turns on to the company logo boot up screen (which is normal) but stays at this screen. It flashes the pattern over and over so the processor is obviously still running .
It should then go to the home screen but just continues to flash the boot screen.
I tried to reload the firmware but the Rockchips batch tool doesn't work either. It sees the tablet but stays at "pink" on the indicator screen. It doesn't turn green (which it needs to) so the firmware will not transfer to the tablet.
I have reset via the reset button, flattened and recharged etc but it wont start up
.
I tried booting holding the volume + and power buttons and it comes up with an image of 2 penguins? Then it shows a vertical android bot for a second before showing one lying down with a " !" symbol above it.
I guess the firmware is corrupted but without the ability to reload I fear I may have a brick!!!!
Any ideas?
Cheers

Hi,
i had the same problem some time ago and the way I solved it was by flashing again the original rom.
Your issue might be the driver installatin on the PC to recognize the tablet as a M30. I had to use an XP to be sble to install properly the RK3066 drivers.
Also try tomuse another usb cable. The one it comes with the tablet is quite patchy and I had to use a good quañity one.
Dont give up, if you ger the endless logo loop I dont think it is bricked.
Good luck.
Hey guys
The problem is that whenever i turn on the tablet it turns on and stuck on the boot logo which the brand name of this tablet and never skip through it , as i tried to enter the recovery mode by pressing the combination keys but no succeed , used "Android multi tool " software , connected the tablet to the PC and tried to use the software but it says that there is no device connected and the device manager has identified it as "Android ADB Interface" , i have searched a lot about "entering the recovery mode" for this brand everywhere but with no luck :crying:
it's brand "Compu Tab BY-7071" but seems to be unknown brand unfortunately, so i managed to open the back cover and to get the CPU's brand , it's "Allwinner Tech A23" and i attached some images below.
i have tried almost everything but with no luck !
is there any way left to restore this dead tablet ?
maybe if i try to disconnect the battery from the circuit board for a while to discharge will work ?
by the way the problem started when i rebooted the tablet into the Boot Loader from the TWRP app i have it installed from the google play store .
Please guys help me , Thanks very much

My smartphones ACERZ130 and WIKO GOA are blocked on a black screen with the logo of ACER or GOA. The buttons and the touchs doesn't works. The smartphones are not detected on a computer. Factory Reset, Reboot System. The screen still displays No Command message on black screen and doesn't reacts. Is there any way to repair?
So I have this one month old TCL P60 series Android TV, the model is U55P6046 to be exact.
After playing around with deactivating system apps (not rooted) the TV does not seem to finish boot.
After the TCL logo, I see the google android logo, but the boot never finishes. I tried google to see if I can find a way to perform a hard reset / factory reset somehow by entering recovery mode. But I can' t seem to find a way. There is no reset button or hole (which apperently the ROKU TV US model seem to have).
The TV has only three buttons on the bottom (left arrow, power and right arrow) but those don't seem to do the trick either. I tried all the sequences and everything I found for other Android TVs like Sonys, but I could not enter recovery mode.
Also the website (tcl.eu) is not much of a help either, does not mention anything related to a problem like that.
If someone has experience with a problem like that, feel free to help
Thanks!

Download the new firmware from tcl website and put in a usb pen. Under the tcl logo on your tv there’s 3 hidden button. If I remember correctly you can enter in a sort of recovery mode while holding down the center key at boot.
The history of the tablet
My father bought this tablet to use as a GPS navigation, but the dalvik chache is filled up completly so the tablet can't boot. So we took it back to the person whom we bought it and he reinstalled the operating system on it, but the main issue is left unresolved. That was about 5-6 years ago. After some months I read about this topic and I figured out how can I clear the dalvik-chache my self, but I can't solve the issue permanently. I left the tablet on the shelf for years, and now I want to completly repair the tablet. (My main purpose with this is to learn how these things work.) But now I can't wipe the dalvik chache with DDMS because it doesn't recognize the device.
From the tablet
The tablet is a Navon Platinum Explorer (which is not a Navon tablet) and there is another tablet called Evolio Evotab Fun wich is almost the same.
Specifications
OS: Android 4.0
Screen: 7 inch TFT LCD capacitive tuch screen, 800x480 pixels
CPU: 1,2GHz, Cortex A8
GPU: Mail-400 ghraphical cpu
Symptoms
When I simply turn on it displays the android logo and stuck there.
If I press [Vol Up]/[Vol Down] + [Power] it connects or if already connected to the PC it disconnects and doesnot display anything.
Windows 10 doesn't see the device, but the Oracle VM shows as an USB device with name: Onda (unverified) V972 tablet in flashing mode
I stuck at
finding a boot.img that I can try to flush on the device, but I also don't know that this is possible because nothing recognize the tablet (I tried with fastboot, adb and ddms).
My goal with this tablet is
1. Fix the bootloop, so the device can start
2. Install some kind of Linux on it
