Hi,
I have iBall Slide i701 Windows Tablet which is stuck at boot screen (originally it had Windows 8.1 but I upgraded it to Windows 10). Now, request to please share the step by step guide to reinstall/repair Windows 10 / 8.1 in the tablet.
Thanks,
Vijay Gupta
Hi!
I dont know your device but by default the steps will be:
1 - Find, download and create a boot pendrive with firmware.
2 - need a OTG cable to plug in tablet
3 - Figure it out how to boot from pendrive, maybe a combination of keys like volume up + power, etc.
4 - plug OTG with pendrive in tablet and try to boot on pendrive.
5 - If successful you will able to recover or reinstall firmware.
Will be something like this I guess

I succesfully downgraded my shift to XPe. All worked fine for many days.
I replaced boot.bmp in windows directory to overwrite common windows boot logo.
After reboot I forget an USB stick (probably with active partition) inserted in USB port ... and I suddenly removed it after bios screen... from that moment XP refuses to start and blocks itself before loading boot screen.
I removed USB stick, tried to load bios default etc etc... no luck.
How can I do ? Can the HD be failed ? How can I do to know for sure ?
Perhaps booting with WINPe ?
Any advice much appreciated. Best regards.

hello i have opad p10 oem version of advent vega after some market application install first my desktop window gone then i tried to restart in recovery mode but tablet is no screen cant inter in cwm only white circle with andriod robot with in upear micro second and gone pleas help i cant connect with my pc because usb problem any method to boot or flash with sdcard i have some knowledg about linux and lablet install 3.2 9n1 thanks sorry for my bad english
As far as i am aware the only way out is to reflash the stock firmware, without usb your a bit stuck. what is the problem with the usb connection?
i am trying 3 systems xp w7-64 w7-32 all are device not recognized error in device maneger is yellow mark unknown device
You need to install the usb recovery drivers. They are on the advent/pov websites. I assume there the same as your tab.
i cant access my tablet because i have usb not recognized error i want any alternat method to flash my tablet rom like sd card or usb drive thanks
no one solved my problem any idea if i use usb to serial cable or usb to lpt cable
You need to sort the usb driver issue. That will solve your problem. As far as i am aware flashing the stock rom with any other cable is not possible.

So I have bought a L7 and when I have it the phone is not working, the seller doesnt want to take my money back so I need help with this :S!
No appears to do anything when connected to charger
No led
No vibrates
No emergency mode
When I connect it to my PC it recognizes it as QHSUSB_DLOAD, but neither KDZ or LG update program recognize it :S!!
Someone know how to reinstall OS I think is software issue but I dont know how fix it
Thanks!
Try following the instruction I got from a website.
What is 'qhsusb_dolad' ?It is the situation when you can't boot into your phone,recovery mode and any other visible interface. When you connected your phone to the PC, the LED will flash and your PC will show that they were searching for the drivers needed(win7/8) but they couldn't find .......If it is commom for you to remove the battery when the phone did not shutdown completely or when you ran into 'No-Response' , as time goes by ,it will be inevitable that you come across the 'QHSUSB_DLOAD' situation .
But from now on ,you needn't worry about that for I have found a way out.
Tools needed:
Hardware: A PC running XP and higher (win7/8 recommended) and your usb cable
Software : MIflash and MIAssistent and a certain mi update rom(It is a *.exe file---fastboot file)
Steps :
1. Install the first two softwares described above(Run as administrator) in your PC (You need to disable the enforcement of digital signature while on win8 in the advanced startup (press 7 or F7)
2.Boot into fastboot mode(you just need to do with your two buttons and usually you cann't see the interface for your screen just won't show in this situation) before connecting to PC
3.Connect you MI2/S to your PC via the usb cable and the pc will recongnise it in the device manager panel(if not, update its driver in the unknown device---qhsusb_dload)
4.Open the miflash and click fresh to load your phone's serial number
5.Flash the update rom(the self-extracted-to folder) into your phone and reboot .
Explanations:
Miassistant contains the 'qhsusb_dload' driver for any phone and it enables the PC(Miflash) to recongnise your CPU serial which is the key part of updating by wire.
Tips:
Try this with your other phone, I believe it will work ,too.
I'm supposed to just copy/paste the link.. but the protocol won't let me since I still don't have more than 10 posts. I just want to help. Try this
no OS, no recovery, edl not working...
hey
i'm new here
so hello everyone
i write this post because i have no idea what can i do else....
i try every method i found on xda (without dissamble) and my axon 7 still have no os...
long story short
some time ago i flash lineage 14.1 using Axon7_EDL_Tool
everything was ok
but one day lineage updater tell me there is update to lineage os 15,1
but you have to use twrp
so i download update
put it to sd card
reboot to twrp
Wipe system,data and cache
everything like i read instruction
then i flash lineage 15.1 in twrp
but it stop - saying error 7
i did not uprade TWRP - maybe it is a problem....
now i have no os, no twrp
and axon stop on "your device will boot in 5 second"
bootloader unlocked
usb debbuging on
i have win10 64b, win7 32b, win7 64b
I installed drivers for axon 7,
i bought deep flash cable
nothing helps.....
what happens if you connect the charger to your phone while its off? not to pc, to wall charger
also, does the LED flashes once and then turns off while trying to access EDL? or does it stays on all the time? or maybe never lights up at all?
Always, if you update ROM to higher Android version, then you have to check TWRP version. 1st attempt - try to install TWRP.
I think error 7 means that you didn't flash the Oreo bootstack. If you can get into bootloader/fastboot mode then you can follow this to flash TWRP. Or give this a try, I haven't tried it myself though.
you need los15 bootstack lol.Go to los15 thread,download universal bootstack v2,flash in twrp,then flash rom (oreo rom)
Keep pressing power , volume + and volume - and this will force into EDL.
Then flash universal orea bootloader then recovery. Then u should be good to go
I can't flash anything...windows can't see my AXON7 - this is main problem...
I tried the tools you wrote but they can't connect my phone
I don't know what else can I do to communicate between phone and computer
Change the cable.
O tried 4 USB and 2 deep flash...
Pressing power , volume + and volume - will turn the led notification red right?
Then you connect the phone to the PC.
You have to check the device manager, what you see there?
Can you get into FTM?
Vol down and power button.
Try installing Zadig drivers and see if that helps
In the device manager in windows you need to see
Qualcomm HS-USB QDLoader 9008
If all drivers are setup correctly
Try installing twrp via fastboot.
Hope this helps
Nothhhing appears im device manager...
Still nothing..
what happened when you press both volume button and button together? for Oreo it will just show black screen or it will show FTM mode on the screen if you on older bootloader. Keep pressing the 3 button until it show black screen then plug in to your computer... make sure you windows firewall and security is all turn off.
Can you check on Windows' Device Manager if the Axon 7 is recognised as DFU, after you try to enter EDL mode? (Also, usually, the notification light is red and stays on).
Similar situation
Hi,
I'm in a similar situation. I'm guessing my recovery was corrupted. I even disassembled the unit to try to get it into EDL mode, which may be working but the device is just not recognized by my computer, though it does charge. My next step is to try replacing the usb connector, or just move on.
Good luck!

Hello,
I was in the same situation and this tuto saved my phone

Hope this works for you !
Hello guys,
My Nvidia shield 2015 (16GB) (not Pro) stopped working suddenly. GOT POWER but BLACK SCREEN.
Yesterday night, I turned off normally like everyday. This morning when I tried to turn ON using the remote, but no power. Unplugged the power cable and plugged back in. I see the power green light but black screen on TV. My shield 2015 is updated to the latest firmware v8.2.0 few months a go.
I want to boot the shield in Fastboot but the command ----> adb devices ---> cannot find my device, I installed the fastboot drivers and minimal fastboot & adb from here (also when I plug the shield to my PC Windows 10 - I see "APX" unknow devices (see attachment APX driver.PNG). I'm using the original nvidia micro usb cable.
[GUIDE] How to flash recovery image Nvidia Shield TV using FASTBOOT hardware method
All of the instructions I found for doing this weren't exactly clear, so I'm writing this out in a way that even dummies like me can understand. So, my Nvidia Shield TV got soft bricked when I tried to update my TWRP to this version. First, you...
forum.xda-developers.com
1) Install FASTBOOT DRIVERS: https://developer.nvidia.com/gameworksdownload#?search=SHIELD Family Windows USB
2) Install Minimal FASTBOOT & ADB: http://forum.xda-developers.com/showthread.php?t=2317790
Also tried the instruction to install the driver by selecting either from Nvidia sheild
- Tried SHIELD_Family_WHQL_USB_driver_201801 --> Select android_winusb.inf --> Tried "Android Bootloader Interface", "Android ADB Interface". See attached "Nvidia How_to_Install_Drivers.pdf"
Android BootloadervInterface" and "
- Tried Universal_Naked_Driver_0.73
- Tried adb-setup-1.4.3.exe
- Tried platform-tools_r30.0.5-windows
Not able to see my nvidia in adb devices.
I followed the proper instruction to put the nvidia in hardware fastboot, as follow: See attached "NVIDIA HowTo-Flash-Recovery-Image.pdf"
"Hardware Method:
- Disconnect power cable
- Connect power cable to SHIELD
- As soon as the green LED turns on -BUT NOT BEFORE- hold down the power button
- Count to three, then immediately release the power button
- You should now see the fastboot menu on the screen.
- If the standard boot process starts, disconnect the power cable and repeat
the process increasing the count in the previous step to 4.
NOTE: You should leave the HDMI TV connected to SHIELD at all times."
Absolutely the same problem here! nVidia SHIELD TV Pro (2015) worked fine about a month ago was turned off normally and wasn't used after that. Several days ago turned it on and nothing except green power light. Stuck in APX too.
Please help!
2020 edition and in the last month or so my 2020 Shield TV 4K HDR is also having issues with the screen blacking out at random times. Tried multiple refresh rates. Plenty of remote actions can restore it until the next random time it blacks out again, sometimes the next minute, sometimes hours later. Happened 6 times in one Youtube video and seemed to correspond with scene changes.
edit: of-course NOW that I post something here, I find search results everywhere.
