I tried to connect it to Computer via USB. apparently, WinXP cant not find the device or any USB device for that matter. But somehow when I hold. and press Back key and Power button, the device LED is on(means somehow alive) with a blank screen and WinXP find ?USB Device!(?)
How to I restore my tablet! please help...

Model:iBall Slide i6012
RAM:1GB
INTERNAL MEMORY:8GB
SCREEN: 800×480 CAPACITIVE TOUCH

Android Version :ICS 4.0.4
Please help me......
I've tried "use pin to restore " and "button combination " but not luck!
Before installing this,I install another WORKING(KIND OF) cwm modified. img.
You need a recovery specific to your device, provided you flashed it to the correct, i.e. recovery, partition.
thanks

The problem is that Window can not find my device. Sometimes it only appear as USB device and other times it doesn't recozniged at all. I tried updating ADB driver but that dont do any help...
http://forum.xda-developers.com/showpost.php?p=20058157&postcount=1 try these.
also, "A. Install the drivers
1) Do not install the Samsung drivers or the pdanet drivers, or any other driver you come across. If you have, and you are SURE they are working properly, fine, leave them. Otherwise uninstall them if you are unsure;
2) Download the drivers from here;
3) Install the drivers. This step is the only part of the entire process that is not easy to explain, and may cause users some issues, depending on what drivers they had installed previously, what OS they are using, etc. etc. Bourne-nolonger has put together a very detailed step-by-step on how to install them. If you don't know how to install them, have a look at his post here. Note that the driver has to install twice: once when your device is booted normally (not required for this tutorial) with USB Debugging enabled in Settings, and once when your device is booted in fastboot (i.e., bootloader) mode (which is required for this tutorial). If you are using Windows 8, you will need to do this before installing the drivers."

USB is death!
hello again!,
I tried that and it does not work!
Computer can not even find my device.
When I plug in charger or USB cable,tab is light up and display iball logo and from there it stuck!
I mean it stuck forever!
What is APX mode?
Somehow when I press Menu and while still holding I pressed the power button simultaneously and my Computer Show "Unrecognized USB Device".
Please anyone help me. I dont even have the stock firmware to flash(if required) with!
Their Customer service is neglecting me and I'm really pisses!
Give me some light anyone
fastboot can not even open in my computer when I download and try to open! it said "can't find Winusbapi.dll"
while "winusbapi.dll" was in the same folder as the "fastboot.exe"!
I'm very new to this and it would be a great help if you can guide me to revive my only tablet!
After a little research, do you mean this recovery? [Not cwm at all] http://www.slatedroid.com/topic/35183-custom-recovery-for-c8a8m7/
Did you choose an option to flash it through partitions and storage menu? Did it allow you to back up your stock setup first (hopefully, if it is cwm-modeled)? If not, then I'm not sure I can help. Looks like your recovery is a recovery AND a kernel, packed into one [just leaned about this from a recent xda story]. I also found this: https://github.com/namko/midRecovery/downloads, with several other BETA versions. Maybe it would help you to google "iball slide". There is a stock 4.1.1 image on xda, which could also help. But overall, it looks like there is not much development for this device, and you should've researched the risks BEFORE tampering with your device!
p.s. I do not know what apx mode is. Also, is winusbapi.dll something that needs to be installed? Click it and see!
completely invisible to Computer.
Hi, can you show me the stock 4.1.1 image. I tried to find it but couldn't get it.
Please post a link here....
No, I did not flash with that modified recovery.
I'm. still amaze how a recovery.img can kill my tablet.
Im stuck in iBall logo. whenever I plug in tablet light up even if I switch it off before charging.
Window can only find my device as "Unknown USB Device ".
I updated ADB and still doesn't work.
I tried google and can not find anything other than piece by piece similarities.
all I want is to flash the stock recovery back!
I can not do it because my ADB is not recognizing my tablet!
I really appreciate your help though!

What ID "Unknown USB Device" in Device Manager?
I was wrong, it's an AOSP based rom; but it's a beta, and i will not recommend it, as it is probably quite far from stock. You didn't answer if that slate droid link is the recovery you took. That says it is not flashed, but rather externally booted.
This kind of recovery.img could kill a tablet in the following way: it looks as though these devices have both the kernel and the recovery together. [there's a recent xda article about a sony bootloader that addresses this.] If the kernel is bad, the device does not boot. Can you try a factory reset from your recovery's menu? So which recovery do you have, i.e. what does it say along the top?
can't see recovery menu

No, I did not flash with that recovery link you provided.
And I can not go beyond the "iBall" logo in the tab. So,no recovery menu. Also I tried all sort of Factory reset like "key" combination and "pinhole", none of them works!
can you help?

[Q] Broken tablet in recovery. Cannot connect USB from windows

Acer Iconia B1-A71. Stops during boot at Iconia icon. Factory reset didn't help. I can get to recovery menu. No options help. Need to get a new img to the tablet but windows will not see it in recovery mode (even though I have the correct USB drivers from Acer)? "Unknown USB" message when I connect or something.
I think I have the necessary files downloaded on my computer to fix this from scratch, I just cannot talk to the tablet????
I do have an old laptop with Linux on it which I can maybe try tonight? Any help or advice would be so much appreciated.
Thanks in advance.

archos 80 cesium no software need some help

hello
i need some help i am kinda clueless i have a archos 80 cesium
with no software at all no recovery etc
the only thing it does is boot logo and after like couple min it goes on no bootable device hit any key
its normal a windows tablet
anybody suggestions ?
Less info how you get it bricked that way, which maybe is helpful to know. Custom recovery, stock?
Whatever i guess only chance to unbrick is by flashing stock-rom
Stock rom is not at ftp://support.archos.com/Smartphones&Tablets/
Seems like it has a SDE firmware?
https://www.archos.com/de/support/support_tech/updates_dev.html
guess you find some answers here:
https://forum.xda-developers.com/showthread.php?t=1468925
Not sure if I should bump this thread, but thought I shall leave my two cents here.
I feel you have corrupted the boot or the internal storage. Since this is a windows tablet, i recommend trying to get into boot and check for boot options, in parallel you also also try to live boot a lightweight linux distribution via an otg pendrive and check the internal storage.
there are also windows recovery tools you can try boot via an otg pendrive.
If the bios supports sd card as a boot device, you may try that instead of the pendrive.
I think its the ESC key on the keyboard to enter bios(ofcourse connect it to the only usb port as OTG)

Poco Press any key to shutdown in fastboot

Hlo guys this problem start when i buy a new laptop which 3.0 usb ports. Then whenever i connect phone without fastboot it show press any key to shutdown and phone disconnected automatically.
I search a little and find that this bug is related to 3.0 usb ports.

This is also working for whyred violet etc

It's working without using any usb hub
Can't believe modifying some registry values solved this! I almost went to buy a usb 2.0 cable. Many thanks
This worked for me and I hope the same goes for you all as well (
without using USB HUB and USB 2 port
).
I found the solution here .
Scenario:
1) Phone not detected with fastboot devices command
2) Phone goes into "Press any key to shutdown"
3) Just download this .bat file and run it as administrator
4) Remove your phone, get it back into fastboot mode (Power + Volume Down), connect it again
5) Open CMD and try to run any fastboot command & they'll run successfully.
P.S.: I too got my POCO F1 unlocked by using this with the modded MI Unlock app. Was tired of trying usb hub and extension thing though my PC is intel and not amd. It'll be happy to know how and what made it worked from technical aspect. Thank You.
Thank youuuuuuuuuu!!! for years now i couldnt do fastboot from my laptop only from my pc

Moto E2 2nd Generation 3G (XT1506) Usb Debugging Help Please !!!

Hello, I Have A Moto E2 2nd Generation Which Boots Up Completely Fine, But Its Display Is Gone.

Once I Saw Something That Requires To Boot In Recovery Mode And From There We Can Enable USB Debugging But I Am Not Able To Go To Recovery Mode (But I Can Go In Fastboot Mode) Please Help I Wanna Do This, The Thing Shown In This Forum To Recover My Phone
https://forum.xda-developers.com/galaxy-s2/help/bypass-secure-usb-debugging-prompt-t2965462
But I Cannot Please Help!!
@YoYo178
On PC run
Code:
fastboot devices
to check for a valid connection. If phone is connected via USB with PC run
Code:
fastboot reboot
to leave fastboot mode ( means re-start phone normally )
Afterwards run
Code:
adb devices
to check for an established connection. If a connection got successfully established
then you force phone to run in adb-mode
Code:
adb shell "svc usb setFunctions adb"
adb reboot
Now you should be able to recover phone's user data. For example
Code:
adb pull /sdcard/DCIM %TEMP%
Code:
fastboot devices
yes it shows, done.
Code:
fastboot reboot
yes it reboots too.
Code:
adb devices
nah nothing shows in adb devices (USB Debugging Isn't Enabled)
And I Do Not Want To Recover Data, I Want To Mirror Its Screen. Well, There Is A Lil Bit Of Data Too.
I Want To Enable USB Debugging And
Code:
push adb_keys
file Which i got From A Authorised Device.
@YoYo178
You can't enable USB debugging by means of ADB: Having USB debugging enabled is THE requirement to make use of ADB.

Hi there, I had the exact same problem with my moto e 2nd Gen LTE (surnia). First of all this isn't a software issue, it's a hardware one ! Displays on some of those phones were faulty and I had to take it to repair it (just to clarify).
I had an immense chance because just before that I installed a screen mirroring app. I opened it through Google now (it was 6 years ago lol) and blind clicked because I remembered the layout of the app.
If you didn't have that chance you can try with USB OTG cable to HDMI port, and connect your phone to a PC with an HDMI cable. I didn't tried that on mine, so idk if HDMI through OTG works. Good luck with that :good:
