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
love XDA-Developers

Hello,
I have problem with my Samsung galaxy 5 (I5500, Europa). After successfully rooting my phone with "Super One Click v1.9.5", I have installed "Chainfire 3D v1.7" (along with "Root Explorer", "SetCPU for root users", "Quadrant Adv Pro Benchmark", "Spare Parts Ad Supported"). The problem appeared after I've installed chainfire drivers. When I installed them, phone rebooted, and stuck on blinking samsung logo, sometimes vibrates, and repeats (It's called "loop boot" if I got it right). Google search haven't helped much. I can get into "downloading" screen with android with shovel in yellow triangle and "Emergency Dload Mode (ARM9 mode)" with samsung logo in the middle. Can't find right combination to open up "Recovery" or "Fastboot" mode. Found out that if I could get into folder where Chainfire drivers are installed, I could uninstall 'em and that should fix it, but dunno how to do that. "USB Debugging" is turn off, I can remember that clearly. Tried connecting phone to computer via USB and "Kies", but it keeps "connecting" with no results (tried with both "downloading" mode and "Emergency Dload" mode. Looks like computer itself detects it assuming from USB sound). Maybe changing to new ROM would help? Please, any help is much appreciated, I want my phone working so badly, dunno what happened to me today, I would never do anything risky with my phone :-( . And if nothing will work, can I still exchange my phone to new one, knowing that my warranty is not over yet as it has only been 10 months since I got it? Ofcorse, its rooted, but how could they check it if it won't turn on, and its not fully bricked since I can get into "downloading" mode and that another one.
Waiting for your replies

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.
Hello at all guys, I'm desperately trying to install a new recovery to install new rom, I've done maybe a disaster, the phone will not turn on anymore, when I connect it is not detected (with the usual beeping sound on your computer).
I found online a full backup of a MTK6577 (boot.img, preloads, logo, recovery, etc.) I put all these files and made the procedure of flash with the software flash tools, the operation is completed I came out the green circle all that went well, but the phone will not turn on anymore.
The only strange thing is that I can load it with the power supply, this is because I use a cable that makes you see when you are charge(see attached file),this when there is no charging source will turn off automatically.
I have buyed this phone by this store: ([email protected]@[email protected]/snapshot/[email protected]), I tried to apply for a refund, but they are gone (as usual)
I tried to click on the back button (reset), but there is no button on the inside.
I ask for your help desperately, if there is any possibility of recovery in some way, even opening the phone, otherwise they are thrown money.
Many thanks, i hope you help me.
up, please help me
Helloooo,
I have a big problem, cant get my phone running again.
The sad thing is, I just got it 4 hours ago
So heres what I have done to my Phone:
I rooted it with Kingo-Root and then installed a app where TWRP was listed, there also was CWM and stuff and I thought I have to flash my phone there with TWRP to install a new ROM and stuff and I clicked there on flash.
Then it asked me if I want to restart in, I cant remember recovery and/or download mode, I clicked yes and from there the trouble began.
When it starts the Coolpad Logo appears, then it say "Download and install the package?", to confirm volume up, to abort volume down. If I press abort, it just goes off, the restart may leads to the battery charging screen ( usb cable is always connected!!), if I press volume up, it says "Information - Do not disconnect data cable", but it says it for forever, nothing happens.
If data cable isnt connected, it shows Logo and then goes off, doesnt do anything.
I wish I would have never done that, Im too stupid for stuff like that.
Can someone help me out?
Hopefully
Hi are you able to enter in TWRP recovery in orden to try to flash him back to stock rom ?
Sadly no
I read some stuff on the internet, and tried it:
I installed andoid studio on my PC, with all that drivers, connected the Phone to my PC and looked it up in the device manager.
Before it was just recognized as "Other devices - Android" without any information, now I had the Hardware ID and put that into the setup text of Google drivers and installed them.
My PC somekind recognizes the phone. (but not like normally)
Maybe i can get the Stock Rom to phone that way somehow?
Edit: its called adb interface in device manager
Now I tried to set up the stock-rom via YGDP, and well, it kinda worked.
Im now out of this mode.
If I start the phone it makes its starting sound and it response to "key"-presses by vibrating, but, no screen, its just pitch black.
Its not listed in device-manager anymore.
Any suggestions?
bad support.

That is probably because you flash incompatible firmware which does not recognize display of your device .
Search on the internet for another genuine rom and repeat flashing process .
I had alsmost same issue when I flashed Blu Studio D572i with rom of D572a as I remember , was black screan completely but buttons are working (showing light) .
Hey there,
I was actually searching a lot about my problem but I can't find a solution anywhere so I wanted to ask you people.
Here is the story;
I tried to install twrp using a 3rd party Google play app it downloaded and said installed the twrp and asked whether I want to reboot the phone or not. Then phone got stuck in bootloop. Looks similar to the other ones but believe me it is not.
Here is why;
- Phone keeps restarting I can't even charge the phone because of that the battery just gets drained so I can't connect it to the pc
- Can't enter recovery or the fast boot mode I tried all key combinations only volume up+power works for me and it shows 3 selections. Recovery mode,fast boot mode,normal boot mode. When I select recovery mode it shows HTC logo and just keeps bootlooping. When I select fast boot mode it just says fast boot mode initiating and gets stuck there ( waited 5 hours ) when I select normal boot it already doesn't boot.
- I can't charge the phone to flash on pc since I have to have at least %35. Whenever I connect charger it starts bootlooping and never stops. Like literally I tried 24 hours and it never stopped.
- I am using Android 4.2.
Does anyone have any idea on fixing this ? This is my work phone and I can't get it to work. This is really very frustrating.
Can anyone help me get to the recovery mode ? Is my phone bricked ? If so is there any way to recover the phone or the data inside of it ? Any help would be much appreciated.
Thanks
So... any ideas ?
