  1. Since I didn't found any decent guide in english to properly factory reset the device I decided to make one, after a few tests I'm here to explain how to REALLY factory reset this tablet. Preface: I don't take responsibility for any bricked tablet, problems for following my guide Check your V. version of your tablet! Mine is V.3 Requirements: You will need an OTG hub, keyboard, and a flash storage drive. WARNING: I wouldn't suggest you to mess with the partitions by deleting or resizing it with a thirdy party software, since I don't know if the stock firmware script doesn't like that, let me know if this method fixed your partitions to full factory state if you previously changed it! I'm curious. There also two separate partitions hidden from windows I found in Linux, I think they are releated to the DualOS function, just don't touch them! Don't touch/delete anything BIOS releated since you may probably brick the tablet Download links: Official ONDA ROM list: http://www.onda.cn/Tablet_Supports.aspx?id=341 (The latest one are on the bottom of the page) To download faster without problems from baidu I suggest you using a good download manager, or a link exporter Re-Uploaded files made by me (Tested, mantained by me) : W10 Processor, Chipset, Wifi/BT drivers: http://j.gs/710187/z8300-drivers-x64zip Those drivers are needed if you are installing windows 10 manually, however, I won't explain how to do that since you will void your warranty and it isn't the purpose of theguide. W10 Touch drivers: http://j.gs/710187/touch-driver-v80-plus W10 July update (outdated): Part 1: http://j.gs/710187/w10p1jul Part 2: http://j.gs/710187/w10p2jul W10 Anniversary update: Part 1:http://j.gs/710187/win10anuppt1 Part 2:http://j.gs/710187/winwin10anuppt2 Android: http://j.gs/710187/android-latest Re-Uploaded files made by others: https://cloud.mail.ru/public/MzuV/BwQAH5T7C (A bit outdated, not tested) Introduction: To factory reset the tablet you MUST flash Android before everything! That's because the android install will overwrite the current Windows partition. Make sure your tablet is fully charged WARNING: Since this is a Dual OS tablet (Different from Dual Boot, check google) it has two BIOSes mode, because we're going to flash Android, we need to change the BIOS mode to Android, by simply booting it from the DualOS Menu, or by clicking the button from windows. More detailed steps to change from the bios down there. Android flashing: USB preparation: We need to create an USB disk or a tf card with the android files you downloaded on it, and booting them from the tablet Download the Android zip you want to install Unzip it Plug an USB drive, you can also use a tf card with enough space Open your windows command prompt as adminstrator Type 'diskpart' Locate your USB drive by typing 'list disk' 'sel disk x' where x is the number of your drive 'clean' 'create partition primary' 'format fs=fat32 quick' Now close the prompt, and go renaiming the drive from windows explorer to "android" Now copy EVERYTHING to the disk Installing: Once you're done, you're ready to install android. Make sure you were on Android before shutting down, plug the otg hub to your tablet, plug your keyboard and the usb drive (or the tf card) Power on the tablet, and press 'ESC' on your keyboard, you should have booted on the bios Go on "Boot Manager" Select your flash drive and click enter Wait, the script will restore everything, the tablet will reboot automatically If somewhere you got stuck at "flashing", try pressing enter from the keyboard. If you got errors, you probably have problems with the storage. Now you're done! Windows flashing: USB preparation: You will need an huge USB drive, minimum 16GB and you can't use a tf card there since windows doesn't detect them unless you have an USB adatper! We must firstly flash the win10PE_xxx_x64.iso to the usb. Once you downloaded the files and unzipped them, install ultraiso from the official site (or try the pirate way) but we must use the ultraiso executable included into the firmware Try to copy the executable on the UltraISO folder on C:\Program files, the program will be in chinese, don't worry about that Open the win10PE iso with Ultraiso Plug your usb drive and go there Be ready to flash the usb drive with those options Open the Windows disk management tool (You can by right clicking the windows bottom left logo and click 'Disk Management') If everything went smoothly you should be in this situation, you've created the EFI partition of the installer. Now, you just need to format the other partition (not the first one) with the label 'WINPE' and using an NTFS file system Like before, copy everything on that partition Installing: We're done with the usb. Now like we did before, boot the disk you've just created. The installer will do everything automatically. Remember to change the bios into windows mode before doing that or you will get BSOD The installer should take place for 25-30 minutes depending on your drive. Now you're done. Your tablet is full factory resetted. If you are stuck on the ONDA logo, try to power down the tablet by pressing the power button for 8 seconds and booting windows from the bios You may need to install additional drivers by using the external keyboard and mouse I tried the older WIndows version and I didn't installed anything since everything was working correctly, I don't know if I did something wrong but trying the latest Windows firmware(Anniversary update), I had to install the touch drivers manually Tips: Changing the BIOS into Windows mode: If you are unable to access the Windows mode, here is another way to enable it through the BIOS. Press ESC when you power on the tablet Go to 'Setup Utility' Go to 'Boot configuration' GMIN: Android / Windows 8.X: Windows If you're going to install Windows, choose windows 8.X, press esc save, and reboot! If somewhere on the process you got stuck, press the power button for 8 seconds and re-try. This guide is a work in progress, help me to improve the guide!
  2. Hi, I'm back again with another particular guide, this time just for android, which will show how to root every V80 Plus rom, this time for real. You probably know that the other guides are not working anymore due to newer roms adding a new layer of protection against modifications. SuperSU zips can't detect this on Android 5.1 since this is something that is used in Nougat or Marshmellow Also, I will also explain how to use newer roms updates (Like the Android V7 version) and make it work on V3 (My tablet) since there are minor hardware changes like the Wi-Fi chip and the touchscreen vendor, I will show how to port the V3 drivers on the V7 ROM which is more stable, and smoother. Prerequisites: Unix environment (Linux, MacOS, Cygwin/MinGW on Windows) I recommend Manjaro Linux, the AUR has all the programs we need here. ADB and Fastboot https://github.com/xpirt/img2sdat https://github.com/ggrandou/abootimg Unlocking bootloader Decent knowledge of ROM tweaking or at least in theory Basic Unix-like systems knowledge A BACKUP, you will lost all data on your device By following this guide I take no responsibility on device bricks or data loss Common steps for both ROM tweaking and Rooting The first thing you have to do is to unlock the bootloader, reboot your tablet from Android and press the down button to access the fastboot mode, then connect via USB the tablet to a PC, you have to enter this command in order to unlock the bootloader (You can also use this tool) also if you want to install TWRP follow his guide. ' fastboot oem unlock ' You will lose all data after oem bootloader unlocking Now you have to extract your ROM boot.img by downloading the correct ROM image (http://onda.cn/search.aspx?keyword=v80%20plus) and using abootimg in Linux/MacOS/Cygwin/MinGW, I won't explain how to compile it. What we have to do is basically extract the initrd and changing ro.secure=0 o ro.secure=1, which will allow for supersu to install without bootlooping and mounting system as rw, using modified system.img's and disable the protection which will put the device into a bootloop state Type the following command to extract the boot.img (You must be on the same folder where you downloaded the boot.img) ' abootimg -x boot.img ' Now several files are created, we need to extract the initrd, put ' abootimg-unpack-initrd initrd.img ' Go into the ramdisk folder and look for default.prop, open it with a text editor change ' ro.secure=1 ' to ' ro.secure=0 ' in the previous folder, type ' abootimg-pack-initrd initrd.modified.img ' This will create initrd.modified.img which includes your modifications, now you have to create a new boot.img with the modifications you made, with this command ' abootimg --create boot.edited.img -r initrd.modified.img -k zImage -f bootimg.cfg -c "bootsize=xxxxxx" ' Please note that in xxxx you have to put the new boot.img size, you can get the exact string by omitting the -c "bootsize=xxxxx" argument, which will give an error that will tell on the left the size you need to put, in my case it was ' abootimg --create boot.edited.img -r initrd.modified.img -k zImage -f bootimg.cfg -c "bootsize=11868160" ' for the V5 Kernel If you have done everything correctly, we got a working boot.edited.img, to flash that into your device you need to go back to the bootloader like when we oem unlocked the device. Put this command from a PC ' fastboot flash boot boot.edited.img ' Rooting If everything went good, you just need to try to install supersu by flashing it with twrp or trying to mount as r/w the /system partition and see if it bootloops, if the rom does not even boot at all even if you just flashed the boot.img you did something wrong. ROM Tweaking and porting Vy android firmware version to Vx tablet Since I got really mad and frustrated by ONDA not releasing firmware also for older hardware revisions (Other may work for your older device, other may not) I decided to extract the drivers and firmware and put them to a newer rom, and it is worth the score. New firmwares are more smooth and stable. As you know, some newer VX firmware ROM may not be compatible with your VY hardware revision device, in my example I had the V3 and I managed to use the V5 drivers (The V5 version works good with the V3 tablet hardware rev) to use the V7 firmware. This may probably work also with a V5 tablet. Don't know if this works with V1 Extracting drivers and files needed Boot.img patching: In order to get drivers working, make sure you followed the steps for creating the modified boot.img kernel which works on your device, cause it is mandatory or you will get a bootloop. Q: Can older boot.img/kernels work with newer/older firmwares? A: Yes, they seems to be pretty similiar so in my example I used V5 boot.img in order to get drivers working for the V7 ROM which has a slightly different hardware Without extracting the following files and firmware you will just have the touchscreen working, but not the wifi or the bluetooth, they require firmwares located into system files! And Without the boot.img you can't do anything with the new rom! Once you downloaded every ROM you need, in my example I had the V3 Hardware revision, I will put V5 drivers which works too on V3 into the V7 ROM, this time we need to find and extract the system.img using simg2img by using this command, easier than saying it. ' simg2img system.img system.img.raw ' Now mount it as read-write with, ' mount -o rw system.img.raw /mnt ' Firmware extracting I needed to extract the following files in order to have everything, copy them on the desktop, if unsure you could copy everything like /etc /lib/ /vendor / because I can't know if you are trying another ROM revisions, because they may require different files, find yours by yourself! (This may be a lot of trial-and-error but the files should be the same, you could try that also with V1 to V5/v7, tell me if it works! Idk about other hardware revisions!) --------------------------------- V5 ROM ---------------------------------------- /mnt/vendor - Other blobs needed /mnt/bin/wpa_supplicant - Needed for the wifi correctly working /mnt/etc/firmware - Proprietary blobs dirvers needed for Wifi, bluetooth and other things to work. /mnt/etc/sensor_hal_config_default.xml - Needed in order to the accelerometer to work. /mnt/build.prop - Needed if you have problems with some apps like Facebook. /mnt/lib/hw/bluetooth.so - In order to make bluetooth working ------------------------------------------------------------------------------------ System.img patching Once you got those files, do the same simg2img command with the system.img ROM you want to put the drivers on, in my case the V7. Mount it with read-write on /mnt or everywhere you like, then patch all the files by copy-pasting the one you extracted before and replacing them on the new ROM using a file manager with root permissions like thunar, nautilus or pcmanfm tl;dr, what I did? Extracted the two system.img's of two different roms Copy-pasted and replaced the files I told you before from the working V5 ROM (Even owning the V3 one but that has the same hardware of V5 I suppose) to the newer V7 rom I want to use is that hard? System.img repacking and flashing Make sure you unmounted the system.img.raw by ' umount /mnt ' put this command ' img2simg system.img.raw system.edited.img ' Now you just need to flash it like the boot.img before, so ' fastboot flash system system.edited.img ' ' fastboot reboot system ' If everything went good , you will reboot into your fresh-new system! Stable if you compare the first sh*tty firmwares they made, there are less slowdowns and bugs like the strecthed windows in the multitasking area. Downloads: Modified V5 boot.img: https://mega.nz/#!OlgygJjK!wTv2L9yfCGsqkV7ShGX4Cub-EGdvh3ROtuZxvMzVGoM Modified V7 system.img to make it work with V3 using V5 firmware: Soon... If you made your own working, please tell me, I will put the links, just specify the ROM and the source drivers you used! Useful commands: From Fastboot: fastboot format system - Formats the android systems Warning: it does not reset the phone, if you reboot you won't have any android system fastboot format data - Formats the /data folders (Program files like apps data) - It does a factory reset, but the ROM will still be the same. fastboot format userdata - Formats the /sdcard folder fastboot reboot system - Reboots into Android fastboot reboot recovery - reboots into recovery From android: ' adb reboot recovery ' Reboots into TWRP ' adb reboot system ' Reboots normally 'adb reboot bootloader ' - Reboots into fastboot
