How to reset NAND/CMOS on board?
Hi. I tried to update bios, because accidentally disabled usb an cant get into bios. In DNX bios update process my tabled asked for confirmation, but i can confirm, because no worked usb. In the end my tablet won't turn on. After turning on, CPU get hot, but nothing shows up, no light, no display.
I really need to know how to do this as well. Is there a possible way to do this, anyone? I believe I've messed up the boot display so it's trying to boot on the micro HDMI instead of the inbuilt display.
@aleksanmi Were you able to figure out a fix?

Hello everyone,
I recently received an Innovatek Inno Pad 10 (chinese android tablet) as a gift and the problem is that the tablet does not boot up. When I got the tablet and turned it on, it showed me an android bootloader screen and then it brought me to the android logo boot screen where it would basically go into an infinite boot sequence. I have tried charging it fully and then turning it on, I have tried un-plugging the battery and plugging it back in. I even tried re-flashing the firmware on the device using a software supplied by the company (it was very hard to find and the company's support is not that great). The flashing process was completed successfully but the tablet would still go into an infinite boot loop (I even tried re-flashing it again with no luck). Here is the worst part, there was a u-boot-nand.bin file included with the program and I decided to try and flash the tablet using that file. Now the tablet's screen won't even turn on, but the power and charge buttons still light on. I think the bootloader got messed up. Does anybody have an idea how to get this tablet working? I have posted pictures of the tablet and its specs.
Thanks
John
hi all my asus memo pad keeps booting to the no usb cable connected screen i accidentally did adb reboot bootloader and now i cant get it to reboot correctly i have not tried to flash anything yet but i cant get it to boot the restore tools from the sdcard it seems hellbent on showing the usb cable screen now :/ is there a way to get it to reboot normally seems dumb that if it did not receive a flash and you power it off it would just boot normally since the os should still be intact..
hello anyone? help please
Same Problem!!! Where do we find the answer????
Tried to unlock the bootloader and the tablet turned off and then restarted with the "no usb connnection"
Searched everywhere and there is no solution posted about this.
Has anyone been able to resolve this? Send me to where you found it.
When it boots it does not read the sd card. It does not try to boot. Automatically goes to "no usb connection".
- have tried : reset button, power and volume up and down, will not boot in safe mode, no response once gets power, goes straight to "no usb connection"
Point me to where I can find the fix, this would be greatly appreciated.
Thanks in advance.
If i find the solution I will post here to help others.
Hello, I have a tablet sitting in front of me that I need to repair. The tablet will only boot to a screen that shows a usb logo and a white bar, which eventually changes to red. It appears that the device doesn't have a working bootloader and will only go into what seems like a download mode. Connecting the device to the computer shows "CLOVERVIEW" in device manager. Attempting button combinations doesn't provide any results. I do not know how to proceed from here. Any ideas?
This video seems like what I'd need to fix it (Intel manufacturing flash tool), although I don't exactly know how to apply this to my device.

EDIT: Fixed it and did a write-up: http://forum.xda-developers.com/memo-pad-7/general/howto-unbrick-hardbricked-memo-pad-t3105945
However, I managed to get myself stuck at the ASUS splashscreen. Does anyone know of a way to get past the splashscreen or force download mode on a MeMo pad?
Hello,
I have a tablet that looks similar to Q88 A13. CPU is wm8801, OS - Android 4.1. So I had stopped using it and left it sit for like 1 year. Now I charged it and tried to turn on, but it wouldn't get past first logo(the one that appears first, not the os loading one) and would attempt to go into recovery itself, but then the android with exclamation mark would appear for a while and then device would reboot and so on and so on...
Then I triggered a hard reset with a button combo, but it didn't really help. Tablet stopped trying to go into recovery and simply kept getting stuck at logo.
I can't access recovery, and neither ADB nor fastboot is working. PC with win 7 reports it as unrecognized device and other PC with win xp doesn't even see that anything is connected to it.
I've tried unsoldering the battery, completely discharging tablet without it, soldered it back on, but didn't help.
Help?

Try Livesuit 1.11.
I've used it to load several ROM's
I'm currently running FaaastJB v2.5 found at http://forum.xda-developers.com/showthread.php?t=2447819
So my mom and I have the same phone, a Huawei P Smart 2019 pot-lx1.
The problem
The phone started doing a boot loop anytime you try to turn it on.
It vibrates and shows the Huawei logo like normal, but after the logo the screen turns dark (not off, just dark, the backlight seems to still be on).
Sometimes after this black screen, a 'recharging' icon is visible in red for a brief moment. It's a red circle with a red lightning symbol in the middle.
It does this regardless of whether it's plugged in or not.
I have no idea what this means because as far as I'm aware, the device can function fine without power (see further down below).
After this black screen or flashing the red recharging icon, it just reboots and does the same.
What I tried
The phone refuses to open Erecovery mode (hold volume up and plug in the device). I have confirmed that this method -should- work since I tried it on my own phone of the same model. In the case of my mom's phone it just shows a black screen like normal.
I can get the phone into fastboot, which is great. It tells you to open HiSuite on your computer, which I do, only for HiSuite to tell me "Your device is not supported for system recovery". Furthermore, any commands that could help me return 'Command not allowed', this is returned from the bootloader of the phone and is NOT an OS permissions issue. I've tried stuff like booting into TWRP or wiping userdata this way but it's simply not allowed.
Regarding the battery, I've tried unplugging the phone while it's in fastboot mode. It just stays on like expected and doesn't turn off, so I don't think the battery has no charge.
From what I gather online, the phone has an FRP lock which prevents you from doing anything that could result in the phone getting a reset. FRP can supposedly be disabled, I've tried dc-unlocker but it simply didn't work, presumably the phone is 'too new' because it wasn't in the model list. (I used detection & then the blue nuke option that said Temp FRP unlock or something like that). There are sites that offer FRP unlock passwords which can be used with 'fastboot oem frp-unlock XXX' but I REALLY don't trust these sites and the prices are expensive.
USB debugging is not enabled and I cannot possibly enable it because the phone will never boot, hence I cannot hop into adb and disable FRP that way or do anything else that adb could. I'm essentially stuck.
I also tried some random things like holding volume up + volume down + power during boot. I have also tried countless times to get into erecovery but it simply will never get to that point.
I also tried downloading the phone's firmware and putting all the files where the UPDATE.app is also located in the 'dload' folder on an SD. I also tried putting an 'update.zip' in the root, but this didn't do anything and I think it's pointless unless you can boot into erecovery.
My mom and dad suspect they damaged something related to charging the phone, either the pins or something inside the device by inserting the charger agressively, is that possible at all? It could explain the red charging icon regardless of battery status, but I'm really not sure.
Same problem!
Hi I have the exact same problem with my huawei. Could you able to solve your problem? If so, could you tell me how?
Thank you in advance.
