[Resolved] Allwinner A23 tablet black screen & Unknown Device Error - General Questions and Answers

Hello,
I have this tab for the last 2 years and it was gifted by my friend. The tab was going well until the day I tried to install CWM and it got stuck in the boot logo. I searched the net to find out some way to install the stock firmware via SDCARD and on inserting the sdcard and restarting the tab, there are some vertical colored lines on the screen and the screen was almost white but I could faintly see the boot logo.
I powered off the tab and on restarting it the screen was blank (black screen). I connected the tab to my computer and I see it was showing as unknown device in the device manager. after many search I could not find any proper driver for the tab and it won't recognise the older driver installed in my system.
I have also tried ADB driver search but the ADB tool does not recon my tab either.
Please HELP !!!!

My phone was running on CM 10.2 nightly which is Android 4.3.1...!
Device was not recognized in windows 7 completely , no plug and play options are avalable or not shown even in the device manager...!
Tried to put Fastboot.apk in the memory card and try to get it recognized in the system but failed...!
I want to get my phone working again...! Any method to change the kernel will be helpful...!
Can I tried it with Odin? Or any software like odin to work with...! Any hardware component which I can use for getting it fixed...!
Is it necessory to get it working with linux for better results...?
Any help will be appreciated...!

[Completed] [Q] completely bricked Samsung galaxy tab sch i800

when put on charging,the battery logo appears and then gets disappeared ....the whole screen turns off and flash turns on by itself and remains on until removed from charging .
my laptop doesn't recognize it ....i don't even know if its charged coz i think maybe the flashlight takes up everything ...hadn't put it on more than 2.5 hrs coz it gets freakin hot.
i have everything with me :its stock files like factory ,param ,zimage,recovery ,database ,etc and heimdall.
just tell me a way to get it recognized ....even i installed drivers for the tab.
can get it in download mode......
does it needs drivers of its own:fingers-crossed:
Hi, thank you for using XDA Assist. I'm not sure if you can recovery it in the state you described. But, when booted into download mode connect it to your pc. Go to device manager on the pc. Do you see an icon with a yellow exclamation mark? If so right click on it and update the driver. Go to where it lets you choose from a list on your computer. Choose the Android adb composite interface. If it works use Odin to flash the stock firmware.

[Completed] M4 SS1060 Bricked / Help Please.

I guys I'm a noobie at this Stuff... But I make my Struggle, even trying it
I have a M4tel model SS1060 from Telcel, the phone was Ok, just one day it freezed , I removed the battery and when I put it back to the phone it get sttucked at M4 logo
So, I found at the web :cyclops: that with SPflashtool I could make it boot up correctly again, loading again the correct ROM or FIRMWARE with it:
I was making this procedure on a laptop with Windows 8.1pro 64bits.
1.- I get the firmware from MTK page I found
2.- I installed the mtk VCOM preloader drivers succesfully
3.- Extracted the RAR file of the Firmware.
4.- Opened Flashtool, I selected the respective scatter.txt file for my device, put the icon on "Donwload Only".
5.- I unpluged the battery, and conect it via USB, the program started to send the file . After a few secconds a error ocurred saying that the PMT was wrong. So i Try it again a few times, even with other version of SPflashtool, and different firmwares for the M4 ss1060 (diferent mobile operators ROMs) without good results.
At this point the phone was in the same condition... I could boot it into recovery normaly, but when triyng to boot it up it keeps stucked at M4's Logo.
I found that this issue was supposed to be fixed setting the program on "Firmware Upgrade" instead of "Download Only". So I make the same process changing it to Firmware Upgrade.....
7.- The progam started succesfully, and loaded the file completly with no errors, after eight minutes the "ok " icon" was shown :fingers-crossed: .
I unplugged the phone from the PC, insert the battery and nothing happened ANYTHING. I think that my mistake was to put "Firmware Upgrade".....
The phone keeps OFF I plug the Charger and it does not turns even the screen to Say "I'm Charging" :crying: I can't even get it into recovery mode, no logo screens. BUT.... When I plug the USB from the PC to the Phone I see that the Device Manager detects the phone with the Vcom Preloader of Mediatek.
So I tried to load the firmware again with SPflashtool on Download mode, the program send the file correctly, and it takes long as ten minutes showing the "OK" icon. But the phone keeps OFF, it makes nothing....
So I wonder If someone knows what to do, I was thinking on install a custom recovery, having on that the problem may be that I damaged the recovery of my phone making it unaviable to boot up. But I'm not shure, and I haven't found information about it.
I just knows that my phone has a MT6572 Chipset, I wonder if some one knows what to do.
Thanks.
