[Solved] Onda V919 Air Dual OS Fix non booting Tablet - Android Q&A, Help & Troubleshooting

So, as the story goes, I accidently bricked by tablet, by rooting it.
Now all I have is.
- EFI Shell
- EFI OS
- my USB Stick
I managed to boot the stock 4.4.4 firmware downloaded from "" and it flashed it's files (system.img boot.img etc.)
However the tablet still refused to boot.
Nevermind Fixed it.
==================================================================================
=======FIXNG you tablet (Onda V919 Air Dual OS in my case ) WITHOUT Fastboot===================
Disclaimer: this WILL completly erase your Tablet and REMOVE THE WINDOWS PARTITION if you had one
It is advised to remove the Micro SD from your TABLET PRIOR USING THIS FIXING PROCESS, it MIGHT GET ERASED
All you need to fix your tablet (as long as you can still access the Bios Screen via USB Keybaord and pressing ESC during boot) is:
- USB OTG Adapter
- USB Hub (preferably self powered over USB)
- USB Keyboard
- USB Stick (formatted FAT 32)
In my case I required the Firmware "V919_Air_DualOS_4.4.4_V1.0.0_v7" (Kernel Version: 3.10.20-00004-gf8a8ae3-dirty).
#00 Fetching the Firmware
##This is the step I cannot help you with: You need to aquire the corresponding FW for your Tablet (it will be a *.rar file with at least 500MB I surmise)
1. Extract the files from the rar to the USB Stick (formatted in FAT32)
2. Connect the USB Keyboard to the Hub
3. Connect the USB Stick to the hub aswell
4. Connect the USB Hub itself to the Tablet (by USB OTG)
5. Turn the Tablet on and press "ESC" immediately & hold it until you enter BIOS (this SHOULD work, even if you tablet refuses to boot into Fastboot via VOL+,VOL- & Power hold)
6. Change the boot order inside "BOOT" to 1. EFI Shell
7. Press F4 and "Save and Exit" (leave everything connected and don't touch the Tablet)
8. The Tablet should now reboot to EFI Shell
9. From here on things should go automatically (startup.nsc should be automatically read from the stick and should autoboot the Recovery files)
[[startup.nsc should contain this line (if you open it in the Editor of your PC): efilinux-eng.efi -f droidboot.img]]
10. If DroidBoot is on...: biggest you are nearly done !
11. wait for Droid Boot to flash all files (system.img will take a REALLLLLY long time... just leave everything as is)
12. Tablet will reboot in Android Mode
I'd love if there was a subcategory called "Onda Tablets" so s.o. could pin this.
It is possible that such guide exists already, but I had spent the last day just fixing my device... so...)
Please report back to tell me if it worked for you.
If I feel lucky I might add some images to this guide sometime...

Here is my personal experience.
I found that Windows not able to load the USB device driver for the VB71 tablet.
Since Viewsonic does not provide the driver in their support web site, you can download the SuperOneClick software (in fact any software come with the Android USB driver) from cnet.com
Then, plung the tablet to your PC (do not Enable the USB Connection) when prompt by your tablet - Windows XP will prompt that new hardware detected and prompt to install new driver for the “VSM752HC” device (the tablet USB device name). I direct the prompt to use the folder of the SuperOneClick software driver folder - example
“C:\Android software\SuperOneClick\SuperOneClickv2.3.3-ShortFuse\Drivers”
to look for driver installation by windows and windows able to install the driver from there.
Note: Only use the driver of SuperOneClick – this software can only root old versions of Android … not Android 4.x
And you can see that the device now become “Android Phone” in the windows “Device Manager”.
After you have windows installed the USB driver for your Android device. Go and download “Android_Root_1.0” (which support Android 4.x) from sourceforge.net. Unzip it to a folder.
Connect your tablet to the PC with Android USB Debugging enabled and run the downloaded script “ICS_Root_Unlocker.bat” under the “Android_Root_1.0” folder.
It will stop and then start "ADB server" (Android Debugging server) and then prompt you to “hit ENTER key to continue” – wait for the reboot complete and "USB Debugging connection is back ON" before you hit the ENTER key !! This applies to first two reboots.
On the third time, you will not see the machine come back on (seems dead) but wait for a few minutes and just “hit ENTER key to continue” which will complete the final change and perform last reboot.
Just “hit ENTER key to continue” to quit the script.
Note: In the first few trials without success – I was not sure anything is going on and assumes the script is dead. I did a Factory reset on the VB71 tablet to put the Factory setting back before I perform the root script again.
Key points:
- You NEED to install make sure the Android drivers for your phone are installed
- You NEED to put your phone on USB Debugging mode (and connected) for the script to work
- Make sure you DO NOT mount your SD card
- If you still can't get something to run, try doing it in recovery mode (or set it back to Factory settings).
All the best with your rooting !

HOW TO UNBRICK PRESTIGIO 3970b DUO

I recently got prestigio 3970b duo 7 " tablet that is stuck on the boot . With power on it would remain on the first screen and would not go any way, it was not possible to enter into recovery mode or to get recognized by the computer when it is connected via USB port with the classic combination of pressing vol + and power button at the same time .
Here's how I managed to revive :
Things you need for this:
1. AML tool from this link http://www.mediafire.com/download/y86c6f99irj3nme/AML_Flash.zip
Unzip it!
2. Firmware I found at the following address http://yf.value4it.com/Service_Files/TabletPC/PMP3970B/
I have used PMP3970B_20130505_v1.0.7.zip – unzip it!
3. Mini SD card 1GB minimum
4. Computer win7 64bit
5. Tablet stuck on boot with full battery
So this i what i did. I have downloaded AML tool on my computer and unziped it, downloaded firmware for flashing and unziped it (when unziped you will have 3 files, one is .zip file and you don't need to unzip it) , formated in FAT32 my SD card and copied firmware files on it. Now you are ready for tablet.
I have plugged in my USB cable while holding volume + button and short pressing power button about 10 times and computer finally recognize that some device is plugged in it. It will try to find drivers, but it can't be found.
Now you need to go in Control Panel - Device manager and you will see your tablet as Unknown device - M3-CHIP, now right click on it go to properties – driver – update driver, select browse my computer for drivers.
You will find drivers in unziped files of AML tool directory in AmlogicusbBurningdriver folder win7.
Windows will ask you if you want to do this, answer yes. Now it will install drivers on your tablet.
After that you need to go in your AML tool folder and find ImageBurnTool.exe and start the program, it will go to 62% or 65% and it will stop, saying it can't finish, but no worry, now you can close that program and unplug the tablet.
Leave tablet power off and insert mini SD card with flash files.
Now power on tablet by pressing only power button and it will start to flash the tablet by it self.
When it is done it will boot up and your tablet is alive again!!!
Now you can get your SD card out from tablet.
I hope that this will help someone.
This 100% worked for me, a i hope you understand that i am not going to take any responsibility if you break your tablet by doing this.

Thank you sir!
its worked perfectly!!! amazing so much problems and find your solution, thank you very much
Thanks, worked like a charm.

[GUIDE] [Fix] Dreamtab hangs at characters.

Symptoms​
The classic symptoms of the issue are at some point the Nvidia Dreamtab will stop booting and hang at the Dreamworks characters screen and never boot any further. The frequency ranges from once a month to a year. You are able to factory reset and the issue goes away for some periodicity and then returns.
NOTE: If you recently bought a new Nvidia Dreamtab and you have this character freeze right after doing the OTA then this probably isn't the issue, I am working on a different fix for that problem in this thread. If however this solution does fix your issue I'd like to hear about it.
Background​
The tablet uses the linux ext4 filesystem. The Dreamtab kernel requests a filesystem check every 20 partition mounts(typically during reboots) or when the files system is marked dirty(the tablet is hard powered off, or some other glitch). The tablet is missing the fsck binary which is the filesystem checker similar to what you might have seen in windows with chkdsk. Without this file the tablet can not check filesystem and the kernel waits indefinitely for that to happen and your tablet sits and the Dreamworks characters.
Solution​
Temporarily boot to a program(TWRP) that can install the filesystem file on the tablet. To temporarily boot to TWRP the bootloader must be unlocked. The unlock procedure requires erasing all information on the tablet which isn't an issue if you are currently experiencing the problem as a factory reset was the only way to recover anyway. If you have a working tablet and want to apply this fix you should find a way to backup your files prior to attempting this. To better understand how the low level Nabi functions this should be required reading and will help better understand what you are doing. http://forum.xda-developers.com/nabi-2/general/nabi-information-t3229119
Procedure​
Only for Nvidia Dreamtab NV08B. Use this at your own risk, your warranty is void. You will lose all personal data on the device
Link to video Youtube video installation
1) Down load the drivers.
-- There are 3 popular options included in the link from above in the driver section of the Nabi General Information thread. Have them handy for the next step.
2) Download TWRP recovery.
-- The file is attached at bottom of post. DTTWRPinstaller300.zip
-- Note: You can automate some of the bootloader unlock and installing TWRP steps below with the install.bat file if you have a working Nabi.
3) Download the fsck patch.
-- The file is attached at bottom of post. NV08B_FSCK_PATCH.zip
4) Reboot to fastboot protocol
-- With Nabi powered off press and hold the power button and the vol + button until a small menu(bootloader menu) appears. Quickly release both buttons or the tablet will start booting normally. Using the vol- button to highlight the fastboot protocol(2nd option from top) and then press the vol+ button to select it. Note: Depending on if the drivers are installed the screen will change or stay the same.
5) Verify drivers installed or install drivers.
-- Open windows device manager. On Windows 10 type "device manager" in to the Cortana search bar. On other versions open run by pressing the "windows key" in lower left of keyboard while also pressing R key. Then type: devmgmt.msc
-- If you have "Android Device" and it's sub menu says bootloader/fastboot then you are set up. If down by "other devices" you have an unknown device then you will need to install the drivers from the selection and download you made from reading the Nabi General Information thread.
6) Unlock the bootloader
-- This step will ERASE ALL information on the tablet.
-- Unzip the DTTWRPinstaller300.zip to a location of your choosing. If you use Windows built in unzip utility make sure you check the box that says to open when unzipping is complete.
-- Hold the shift key on the keyboard while right clicking on the "files" folder. Then select "open command window here"
-- At the prompt type:
Code:
fastboot oem unlock
Note: You need to move quickly to the tablet and do the next step as there is a timeout
-- On the tablet it will ask if you want to unlock. Using the vol- key select "yes" with vol+ or pwr. If you do this properly in the command window on your computer it will tell you it is erasing the device.
7) Temporary boot TWRP
-- I can't remember if after the bootloader unlock if tablet is at fastboot, or if you have to power off the tablet and do step 4 again. I think you can just proceed.
-- At the prompt type
Code:
fastboot boot recovery.img
8) Get the patch file on the tablet
-- Option A: There are a couple options for this. Check the file explorer on your computer. If you see t8400n as a device you can just copy and paste the NV08B_FSCK_PATCH.zip to the internal storage by copy and pasting in windows. Go to step 9.
-- Option B: Insert a microSD card in your computer and copy the NV08B_FSCK_PATCH.zip to your microsd card and insert the sdcard in the tablet.
-- Option C: If the t8400n does not show up on your computer then you will need to transfer via ADB. This will require you to setup the ADB driver like you did for fastboot in step 5. Now in sub Android Device in Device Manager you should see ADB, if you don't install driver.
--Copy the NV08B_FSCK_PATCH.zip to the "files" folder where you extracted DTTWRPinstaller300.zip. It should be in a folder with adb, fastboot, AdbWinAPi, etc
-- At the command prompt type:
Code:
adb push NV08B_FSCK_PATCH.zip /sdcard
9) Install patch
-- In TWRP on tablet click the install tab. Generally you will now see the NV08B_FSCK_PATCH.zip if you picked option A or C. If not navigate to the sdcard folder. If you picked option B navigate up a folder and find external_sdcard folder and look in there.
Note: For external_sdcard it may be necessary to exit to TWRP main menu and select mount tab and make sure Micro SDcard is checked.
-- Once you have found the NV08B_FSCK_PATCH.zip from inside the install tab you can select it and then swipe to install. You should get verification it completed normally.
I know this is rather old, but I have a couple of these tablets I'm trying to get working again to give to a friend's kids, but this doesn't seem to work. Did you have to have USB debugging checked before the tablets stopped booting in order for this to work properly?
Basically I can do all the fastboot stuff without any errors, but when I try to boot to TWRP all the tablets do is pretty much rotate the screen 180° so the bootloader screen is in the opposite corner and the volume buttons no longer work until I hold power for ten seconds to power it off... Any help is greatly appreciated!

Howto recover contacts via TWRP

My screen has been completely destroyed and I managed to put TWRP on the phone like a blind man and start it.
That means I can access internal storage from the PC via USB.
Now I am wondering where the contacts are stored which I'd love to recover.
I start fearing that I need to apply more hacks to the phone which however is unrealistic given the circumstances.
To be honest I haven't really grasped all the layers of Android OS, but as long as I'm in recovery I should be allowed to access anything, or not?
UPDATE
Looks like I need to access "/data/data/..."
I guess the problem is that only Internal Storage "/sdcard" is exposed over USB. Can that be changed?
BTW "adb devices" shows "unauthorized".
How to access everything? What part of the system is blocking it?
UPDATE2
Almost there, pulled TWRP from official sources, that apparently has the engineering bit set so you don't need any authorization
Now I'm stuck will just "adb pull"ing the entire /data directory cause my crap Windows machine tells me it can't create directories *sigh*
Thanks.
(Oh BTW , it's an S3 Neo (Android 4.4) and TWRP is 2.8.5.0)
For those who come after me, here is how the entire situation was solved from beginning to end.
This is a Galaxy S3 Neo with the display completely broken, no input, no output My PC is a Windows 10 laptop.
* Got odin (flash tool) I used 3.12
* Got twrp (from URL twrp.me and looked for my phone model) I used 2.8.7.0, it's important to have an official/correctly compiled one, otherwise adb may show "unauthorized" or whatever
* Got Android SDK platform tools (includes adb)
Now on the phone, I go to download mode, flash the new recovery and then immediately boot into recovery (otherwise the stock ROM, if still working, will replace the newly flashed recovery again by the stock one):
* Remove and restore power (remove all cables and battery, and put them back on)
* Careful, maybe the phone will start automatically after you give it power in some situations, you have to be fast
* vol-down + home + pow
* wait 8 secs
* vol-up
* start odin 3.12, should see COMx (Windows Device manager shows Samsung USB device)
** untick autoreboot in odin options
** flash new recovery to "AP" (twrp-2.8.7.0-s3ve3g.img.tar)
* remove power (cable + battery)
* restore power (cable + battery) and immediately hold down vol-up + home + pow
* inside recovery I can do anything I want using adb (Device manager shows USB composite device) like "adb shell cp -a /data /external_sd/" (ignore "can't preserve ownership" messages, that because you're copying from ext to fat, no worries here)
* copying to the external sd card was the way that worked, just using "adb pull /data" to copy the data directory didn't work because the Windows part of adb somehow could not create files on the local system, no idea
(I had Windows device manager running all the time with the "Universal Serial Bus controllers" branch expanded, in order to see what was going on. Maybe take a screenshot with nothing connected, so you see the difference.)
Finally, when you're in recovery there are no other layers. Must tutorials talk about adb commands while the ROM is running with USB debugging turned on, which is obviously very much different, and you don't get very far without root(ed ROM).
Now for the contacts, on this phone they are located in data\data\com.android.providers.contacts\databases\contacts2.db (use your favorite sqlite browser to view). Noone says this data is easily readable though
Feel free to correct me if any of this is wrong =)
PS. I must add that during all of this I installed Windows drivers from different sources which made these things work YMMV
PS2. You may be able to use commercial tools in cases like this. However it depends on the level of brickage. I believe some have like advanced recovery options to retrieve files from broken phones where they will do automatically what I did here manually (flash new recovery and stuff). However you always need to make sure your exact device is supported, as always.
PS3. Now you have all the data. You will not be able to just restore another phone to the state in which the old phone was, but at least you have your data in some form. And you have the possibility of deleting everything left on the phone before recycling

HP TP recognizes USB drive (with external power) but empty folder. Please help!

Hello All,
Years ago, I installed CyanogenMod 10.1. The TP works OK. Here's the info:
- Android version: 4.2.2
- Kernel version: 2.6.35-cyanogenmod [email protected] #1 Tue Dec 10 17:10:10 CST 2013
- CPU: ARMv7 Processor rev 2 (v7l)
- CyanogenMod version: 10.1-20131210-SNAPSHOT-VPN-tenderloin
- Build date: Tue Dec 10 17:05:54 CST 2013
- Build number: cm_tenderloin-userdebug 4.2.2 JDQ39E 8d5ffaac34 test-keys
From what I know, external USB can be connected to HP TP via OTG cable and external power. So in an effort to use this HP TP (which has been collecting dust) as a digital frame, I follow this link:
https://www.youtube.com/watch?v=Nc7tlPwFQpg&t=198s
The guy has links to buy OTG cable and Y adapter:
https://www.amazon.com/gp/product/B005QX7KYU/ref=oh_o02_s00_i00_details
https://www.amazon.com/gp/product/B0041CFFBM/ref=oh_o01_s00_i00_details
So I bought (2) OTG cables and (2) Y adapters from the above links.
The power adapter I use is a working 2A one (brand name: Amazon). I formatted the USB thumb drive. Then loaded a few jpeg files to the thumb drive.
When I followed the above Youtube video to plug the USB drive, the app 'ES Explorer' does recognize the USB drive but it shows 'Empty folder'. I changed out OTG and Y cables but still the same: the HP Touchpad won't recognize the jpeg files on the thumb drive.
Please tell me what I did wrong and show me how to fix it.
I'm open to two solutions:
1) Open the HP TP up and solder a SD/micro SD module (I'm a circuit technician and have no problems doing that).
2) Wipe out the HP TP and install another Android version newer and/or capable of reading external thumb drives (I hate wasting a nostalgic HP TP).
Thank you very much for your help.

This is the OTG cable that I use and another one that could not find on line:
Click HERE for 4 Port Micro USB
I had use it with a 16GB USB drive on Evervolv 7.1.2 for curiosity to see how it works and I was very impress with the speed. I was able to play movies from the USB drive and at the same time also connected an USB Ethernet ( I had to incorporate the driver into the kernel ).
It is possible to have more than one USB device connected at same time, like USB drive, Keyboard, mouse and wire Ethernet. The tablet is like a laptop with connections by wire.
If ES Explore recognize the USB drive then the OTG cables is good, but you need another software to be able to read the files. I tried it Total Commander and there was another software to mount the partition, I think it was Paragon:
https://play.google.com/store/apps/details?id=com.paragon.tcplugins_ntfs_ro&hl=en_US
Install that to mount the USB drive and then the files should be available in ES Explore if not then try Total Commander and use the plug in for it.
Thanks but unfortunately none of those work because those methods only work for at least Android 4.4. Please let me know how to 1) wipe the TP and 2) find a stable and newer Android OS / CyanogenMod to install on the TP which will only be used as a digital frame and not anything else (no internet browsing, games, etc.).
All I see is this:
https://forum.xda-developers.com/hp-touchpad/development/rom-evervolv-hp-touchpad-t3923512
or
https://forum.xda-developers.com/hp-touchpad/development/rom-evervolv-7-0-0p1-wifi-t3456292
but both don't have step by step installation guides.
Thanks @HP_TOUCHPAD

If you want to easily wipe the tablet and make it a 100 % Android device and install any ROM then follow this guide.
There is a lot to read, but very simple, flash Automatic_Wipe_ALL and it does everything.
https://forum.xda-developers.com/hp-touchpad/general/hp-touchpad-optimize-android-swap-t3901773
The Tablet can read and write up to FOUR USB drive connected at the same time, attached are screenshots using Evervolv 7.1.2 with Total Commander and the plug in for the USB.
https://www.ghisler.com/android.htm
USB drive tested: 16G SandDisk, 16G Lexar, 8G Patriot
All three USB can be connected at the same time and be access using total commander file manager.
Also I plug in the MicroUSB Ethernet and works with the USB connected.

Thanks. I downloaded 'TWRP Recovery Version 3.2' to my computer, unzip and copy the files to the HP TP root directory. Unplug the TP from computer. Turn off the TP completely then boot it up again. No recovery menu to choose other than WebOS Recovery and some other menu options unrelated to automatic wipe out. So I'm stuck there.
Can I use this one instead?
https://www.youtube.com/watch?v=VP-FH6fS2GI
He basically shows step by step how to uninstall everything by plugging the TP to a computer which already has Nova installed.
Part 2: Let's say everything is wiped out, which android version would you recommend given my simple use of the TP? This is Android Pie 9.0 on Youtube (same instructor): https://www.youtube.com/watch?v=hAuNSoe6euI
Thanks again.

TWRP 3.2.1 needs to be flash using another recovery, if the uImage.Recovery is copy into boot then the file moboot.default needs to be edited and add uImage.Recovery to show in the moboot menu. It is best to flash it as it will create the entry for moboot menu. But now there is a copy there and the /boot maybe full and it needs to be clean.

As mentioned the entry uImage.Recovery must be add to a file in the /boot partition.

boot the Linux ISO file into a PC or virtual machine, place the tablet in WebOS recovery mode connect the tablet to PC and click on Wipe ALL, then install any ROM.
I recommend Evervolv 7.1.2 as that is the one that I used for the screenshots with the USB connected.
Then go to this guide and install the ROM:

To flash a ROM, copy the zip files to the Tablet and using TWRP select and flash.
If you have novacom install on your PC and know how to use it then follow this guide to wipe all.

All those options allows to load Wipe_All to have everything done automatically. Select the best option for you but the outcome is the same.

So I created a bootable USB drive having 'HP_Touchpad_Novacom_Repair_Android'. Change my laptop boot priority to USB and used 'unetbootin-windows-677' to 'Wipe All' the Android version. After that, every time the HP TP is booted, only a moboot 0.3.8 menu appears with these options:
- boot Recovery
- boot webOS recovery
- reboot
- shutdown
Now, I have downloaded these zip files:
- ev_tenderloin-7.1.2-nightly-2017.11.03
- HpTp_MaXtreme_1674_CPU_Universal_Optimize_Swap_Evervolv_7_1_2_Nougat
- open_gapps-arm-7.1-pico-20200520
I need to copy these zip files to the tablet but I don't know how: Turn the tablet on and select 'boot webOS recovery' and the white USB logo appears. Then connect the tablet to a laptop with Windows 10 running Then a message pops up 'We're setting up Palm device'. I open Windows Explorer to copy the zip files to the tablet but there's no 'Palm' folder (before Android was wiped out, I do see 'Palm' folder in Windows Explorer). Can you tell me how to copy the zip files to the table then? Should I copy those zip files to the bootable usb thumb drive then run unetbootin-windows-677 on the laptopn and copy the zip files over to the tablet?

Great Job! now you have a Linux OS with built in Novacom drivers that will always work no matter what.
- boot Recovery
- boot webOS recovery
- reboot
- shutdown
The tablet has been completely wipe and only the Android partitions were created.
boot Recovery is TWRP 3.2..1 by @flitman that allows to flash any Android ROM and works 100 % all the time.

WebOS Recovery is only use to repair the Tablet ( troubleshooting )
Recovery TWRP is the App that is use to flash any ROM.
Boot into TWRP connect the Tablet to any PC, Micro SD will show ( is like a portable USB storage ) It works on any PC there is no need to have the novacom drivers install.
Copy all the zip files to the Micro SD card or USB ( it has different names )
Go to TWRP on the Tablet and select the zip files to flash, when done reboot.
It is very simple the only thing to do is select and flash that is it.
Here are some youtube videos about HP Touchpad Novacom Repair for Android, that shows how is use:

Thanks a lot. I was able to installed Nougat on TP. Try to install Paragon exfat/ntfs software but the software shows it's not compatible with HP TP Nougat 7. Installed Total Commander then install the plug-in (USB Stick, free trial btw) then the tablet restarted by itself. As it turns out, the battery drained from 50% to 0% right after installing the plug-in.
So now I'm monitoring the tablet to see if there are problems.
Also, System Storage and (Android Stock) Gallery both don't see the pictures of the usb thumb drive. The only one app can see the usb drive is Total Commander. I clicked on the pictures but there's no photo browsing app associated with Total Commander so I can't see the photo slides. If you happen to know such a photo viewing app compatible with Total Commander, please let me know.

Always keep the tablet charging, it will prolong the battery life.

That is a limitation of Android but some apps would be able to read the USB, to look here:

I know that using a USB stick is the most cost effective and easy way to set up, but also keep in mind a wireless hard drive, of you can set up a share folder from a PC and connect the Tablet and show all the photos from a network location. There are many ways the tablet can produce a slide show.

When I click on a photo on USB stick in Total Commander, a menu pops up 'with 2 options:
- Download+Open with
- Download+Edit
But whatever option you choose, nothing happens. It can't even view a photo. So I guess Total Commander is trying to associate a photo with an photo viewing app but it can't find such an app.
For ES Explorer, it can open a photo but no slideshow ( I heard that previous version of ES Explorer had that feature) so you have to manually click on the next photo.
Don't bother with Google Photos because it can't detect photos on the USB stick. So for now, I copy some of my pictures on the HP TP internal storage and play the slideshow by running Google Photos.
Hoping one day either ES Explorer or Total Commander can do slideshows.
Thanks for all your tremendous help.
