stuck in a loop between "Diagnosing Your PC" and "Preparing Automatic Repair
I was trying to do a factory restore by going "Settings" -> "Change PC settings" -> "General" -> "Remove everything and reinstall Windows" -> "Get started".
After the Surface restarted it is now looping between "Diagnosing Your PC" and then "Preparing Automatic Repair" and it is not able to get in to Windows 8 RT anymore nor any options for to me select. All I can do is to power off the Surface and when it restarts it will loop again, non-stop!!!
The Surface ignores the "Volume Down" button when I turn it on and starts the automatic repair, then diagnosis and another reboot
Any idea ?
Try this...
Boot to command prompt.
Type: bcdboot
Type: bcdboot c:\windows.
Reboot.

3. Plug in your device via USB. Your computer should be asking install a driver. Install and continue.
4. Now Run mtty and choose USB in 'PORT'
4. type "set 16 0" without the quotes to tell bootloader to boot the OS after reset.
5. type "task 8" to get your device formatted.
6. Now unplug your device and manually reset it.
i hope you will be happy after .. thanks
Do it on your own Risk I am not responsible for any kind of brick.
Your warranty will be void.
Install adb driver first on your PC.
1. Settings >> About phone >> Tap “Build Number” seven times. You will see “You are now a developer”
2. Hit the back button. You will now see a new option in Settings — “Developer Options”
3. Turn on the developer options
4. **In the Developer Options, Enable OEM Unlock (Allow bootloader to unlock)
5. **Enable USB debugging
6. Plug your phone to PC via USB cable
7. open Command Prompt with admin right on your pc and type adb devices.
8. You should then see a pop up request on your Infinix Zero 5 to give your PC USB debugging permissions. Go ahead and allow
9. Type again adb devices it will show your device in list in command prompt (like Some number)
10. Type adb reboot bootloader (your phone will reboot to fastboot mode (a dim black screen will appear))
11. Type fastboot oem unlock.
12. it will ask for permission press volume+ button to confirm and wait to complete. (done, it will erase all your data)
will take more time to reboot first time.
upto step 10 I can see as described, but nothing happens at step 11.

your driver not installed correctly.
when you enter in fastboot/bootloader mode just type fastboot devices.
if there it shows your device then only further cmd will work.
and it shows only if fastboot driver installed correctly.

I could get to the screen where it asks for the permission on the phone screen. But could not muster courage to go ahead. will try some other time once I have full backup.
Thanks again.
Hi, Thanks for the described process. As mentioned above, I am also unable to pass through point 11. I can see the dim screen on the mobile, but on fastboot command, it appears to wait for the device.
Your help is highly appreciated.
is there a way to remove this message after unlocking bootloader ?
orange state : your device has been unlocked
Does your phone not boot into Fastboot? Even when you try:
Code:
adb reboot bootloader
(the software method),
Or pressing volume down and plugging the device in (the hardware method)?
I found a fix!
Here is what I did:
Download all of this:
Uppercut/LGUP: http://downloads.codefi.re/autoprime/LG/Flash_Tools/LGUP/ (both files)
RS988 KDZ: https://lg-firmwares.com/downloads-file/9466/RS98810h_01_0303
TWRP: https://dl.twrp.me/rs988/twrp-3.3.1-0-rs988.img
ADB: https://forum.xda-developers.com/attachment.php?attachmentid=4623157&d=1540039037
Flashing the KDZ
Install the "LGUP_Store_Frame_Ver_1_14_3.msi"
Disable your Antivirus (just pause it for a couple hours or so)
Extract "UPPERCUT_1.0.0.0.zip" and run "UPPERCUT.exe"
Click "OK"
Power off the phone
Press and hold the "Volume Down" and then plug your phone into the computer while continuing to hold "Volume Down"
Release the button once "Download Mode" appears on the screen
On LGUP, the phone should have appeared in the list. If so, skip to step 18, otherwise continue.
Download this: https://drive.google.com/file/d/0B5Lj5sOIvofGSWFINjhuS01vU1U/view
Run "LGMobileDriver_WHQL_Ver_4.0.4.exe" and finish the Install.
Search windows for "devmgmt" and open device manager.
Find the device named "android" or something similar
Right click the device and choose "Update Driver"
Click "Browse my computer for driver software"
Click "Let me pick from a list of drivers available on my computer"
It should have selected a driver named "Bootloader Interface" or something similar. Choose next.
Once the driver installs, close the window and close device manager.
On LGUP, press "Select"
Choose the "REFURBISH" option
Click on the empty box next to "BIN"
Click the ". . ." button and browse for the "RS98810h_01_0303.KDZ"
Click "Start"
If a dialogue appears about partitions being wiped, choose "OK"
Once finished, close LGUP
On the phone, if "Enter a Password" appears once booted, either enter random letters and numbers and submit them 30 times, or unplug the battery, then put it back in, then press "Volume Down" and "Power" at the same time, AND THE MOMENT THE LG LOGO APPEARS release and then press and hold the power button but CONTINUE TO HOLD VOLUME DOWN. Then use the volume and power buttons to select "Yes" both times and wait for the phone to preform a factory reset.
Unlocking the Phone's Bootloader
Enable "ADB Debugging" and "OEM Unlocking" (Settings > General > About phone > Software Info > Tap "Build Number" 7 times, then go to Settings > General >Developer Options > enable both "USB Debugging" and "OEM Unlocking")
Go to Settings > General > About Phone > Status and write down the IMEI number (preferably in a text editor on your computer for easy access)
Extract the "adb-setup-1.4.3.zip" and run "adb-setup-1.4.3.exe"
Reply "y" to everything and complete the install
Search windows for "cmd" and open "Command Prompt"
Execute:
Code:
adb reboot bootloader
Once the phone has rebooted, run:
Code:
fastboot oem device-id
you should get something like:
Code:
Example Device ID (PC User)$ fastboot oem device-id
(bootloader)-----------------------------------------------------------------
(bootloader) Device-ID
(bootloader) CD58B679A38D6B613ED518F37A05E013
(bootloader) F93190BD558261DBBC5584E8EF8789B1
(bootloader)-----------------------------------------------------------------
To generate your unlock key, you will need to paste together the 2 lines of output into one continuous string without "(bootloader)" or white spaces. In the example above, the Device ID would be:
Code:
CD58B679A38D6B613ED518F37A05E013F93190BD558261DBBC5584E8EF8789B1
Write the code down with the IMEI. (in a text editor)
Go to https://us.lgaccount.com/join/terms
Sign up for a LG Developer account. Continue once completed.
Go to https://developer.lge.com/resource/mobile/IssueDeviceInfo.dev
Sign in
Enter your Nickname as made in setup
Enter your email
Enter the IMEI number and Device ID you wrote down earlier.
Click "Confirm"
You should now receive an email with an "unlock.bin" attached. Download said bin.
Plug the phone into the computer
Search windows for "cmd" and open "Command Prompt"
Run:
Code:
cd Downloads
(or wherever the "unlock.bin" is stored)
Then:
Code:
adb reboot bootloader
Once in fastboot, run:
Code:
fastboot flash unlock unlock.bin
Once the phone boots, you are Unlocked!
TWRP
if you want TWRP installed on the phone, follow these instructions:
Run:
Code:
cd Downloads
adb reboot bootloader
Then run:
Code:
fastboot flash recovery twrp-3.3.1-0-rs988.img
Unplug the battery. DO NOT BOOT THE PHONE INTO THE SYSTEM. YOU WILL LOOSE TWRP.
Put the battery back in, then press "Volume Down" and "Power" at the same time, AND THE MOMENT THE LG LOGO APPEARS release and then press and hold the power button but CONTINUE TO HOLD VOLUME DOWN. Then use the volume and power buttons to select "Yes" both times and wait for the phone to boot TWRP. (dont worry, the factory reset program was replaced by TWRP)
Select Wipe > Advanced Wipe > select all except "micro SD" and "USB OTG"
Swipe to Wipe
On your computer, there should be a RS988 device under File Explorer.
If you want stock, Keep going. If not, find whichever rom you want, and follow their instructions, copying the files required to the "Internal Storage" of the RS988 device.
Stock flashable ZIP: https://androidfilehost.com/?fid=962187416754454673 (if you want stock)
Magisk: https://forum.xda-developers.com/apps/magisk/official-magisk-v7-universal-systemless-t3473445 (choose "Latest Stable" under downloads)
Copy the ZIP to the Internal Storage of the RS988 device on your computer, along with Magisk, and the TWRP img you downloaded earlier.
On TWRP, choose "Install" then select "RS988_21d-Stock_Flashable-COMPLETE.zip" and swipe to install.
Once installed, press the home button.
Press "Install" and choose the Magisk zip, and install.
Once done, Press home
Press "Install" then "Install Image" and choose the TWRP image.
Choose "Recovery" and swipe to flash.
Click "Reboot System"
That is it! I hope this helped a few people out. This might need to be standard procedure for all RS988 devices, I'm not sure.
Let me know if I need to change anything, or If a part is confusing to you. I'll see what I can do to Improve.
Thanks,

I have a very old Wikipad tablet, which these days tends to only get used for playing old video games. I hadn't used it for a few months, but now whenever I switch it on I get an error:
"Unfortunately, System UI has stopped"
No matter how many times I tap OK, the error just keeps popping up, with the occasional "unfortunately, Launcher has stopped" thrown in as well.
There are plenty of suggestions online for how to fix these errors (remove apps, empty cache, etc.), but those all rely on you actually being able to access the UI and settings. I can never get past these errors on top of a blank screen.
If I enter the Power/Volume-Down boot menu, I get the options of "normal boot", "fastboot protocol", "recovery kernal" and "forced recovery". Selecting "Recovery Kernel" shows the image of the android lying down with an exclamation mark above it. However, I'm not sure where to go from there. No commands appear on screen and various power/volume button combinations don't seem to do anything.
Does anyone know the correct commands to do a factory reset on a Wikipad (or have any other suggestions as to how to resolve the errors)? I'm not bothered about losing all of the data on it.
Thanks!
OK, after weeks of scratching my head on this one for a few weeks and deciding to post the question on this forum, I figured it out myself a couple of days later
I downloaded Fastboot and Android USB drivers from the links posted here:
Fastboot.zip, ADB, & Android USB Drivers | HighOnAndroid.com
highonandroid.com
I installed Android USB drivers (by ClockworkMod). I plugged the Wikipad in to my laptop (Windows 10), powered it off and booted it holding the power and volume down keys. I selected the "fastboot protocol" option. An unknown "fastboot" device then appeared in Device Manager. I had to manually select the ClockworkMod generic Android driver before it was recognised.
Running "fastboot devices" then listed a device. Running "fastboot -w" then deleted all user data (there's no confirmation prompt, it just runs). It also threw an error:
"CreateProcess failed: %1 is not a valid Win32 application. (193)
fastboot: error: Cannot generate image for userdata"
I ignored the error and rebooted the Wikipad. It then booted in to the first time start-up wizard and the System UI errors are gone. All of the data I had on it is gone too, but that's no big deal.
