RCA Pro10 (Digiin) RCT6103W46 10" Tablet
RK3188 CPU
JellyBean 4.4.2
Problem: Unit hangs on RCA splash screen and therefore will not boot up even after factory resets. Unit was working fine until vold.fstab was edited to change the mount point of the external SD card.
USB Debugging enabled.
adb shell accessable.
busybox accessable.
When trying to obtain su privileges, via adb shell, the shell hangs.
Can not change read only status to r/w status for internal storage and therefore can not push edited vold.fstab back into internal storage.
Have tried several rooting programs (on both Windows 10, Ubuntu 18.04.2 and Mint 19.1 Cinnamon) to obtain root/su status on the tablet with no positive results.
No fastboot option available - only recovery is available via power/volume key combinations.
No viable firmware images availble either from manufacturer or available via internet searching.
Questions:
What software (or via adb shell) would pull a complete set of recovery images from
the unit so that I could install them to an external SD card with the purpose of attempting to boot/run Android from the external SD card?
Would this even be a possible option as I would imagine there would also have to be some method of overriding the original boot sequence so that it does boot from the external SD card?
I hate to think that this unit is totally bricked without exploring all options to try and revive it (including trying to install another OS which from doing net searches doesn't look to promising).
Any input on this topic would be much appreciated...thanks!

Hi, I'm looking for original recovery image for folio so i can return my folio for warranty repair due to the "damaged internal storage" and SD card not detected problem. Other people have that problem but no one got a solution.
There was only one link from dexter
but it does not work for me (maybe due to sd card not correctly detected? sd card can be detected for some other mod though). Also when i open the zip file i notice the files types and location in the "folio stock image" is different from the mod that works on my folio.
Someone seems to have a Folio Original Recovery(apply via recovery).....how to do that actually?
Can it be fixed by fastboot (never done this and not sure what it is about actually) as done here http://forum.xda-developers.com/showthread.php?t=1012980#12482544
http://bb2k.org/folio100wiki/index.php/FolioMod_Issues#Internal_storage_give_problems_.2F_no_enough_space_.2F_internal_storage_results_damaged
If you have sd damage or something like that it must be the mbr .At the end of lost partition method 2 , use this file mbr.mbr inside zip http://www.box.net/shared/suinl2fzqb63jkqaispj with adb
Hope this can help you but you need to install sdk and adb shell on you computer with the correct folio driver to connect your tablet in fastboot
Warning if you re not sure of what you do you should not do this but if it "bricked" it Will not be worst
if you are with Windows seven sometimes it s hard to install proper driver for folio try to use pdanet to do that if you still have waiting for device in adb shell
ive done every root method and still nothing can someone help

Using a new SDCard (not one you have info stored on) make a new MSDOS partition table and add a 50 MB FAT32 partition as the first primary partition. Then make sure you enable to boot and lda flags.
Any SDCARD larger than 50 MB should work but I used an extra 2GB laying around. You can add other partitions to the card if you want, but it is not necessary to allocate the entire card. Any added partitions would need to be manually mounted on your Nook anyway.
I used GParted on my Ubuntu machine to do this but any formating tool should work.
2. Copy Files onto SDCard
You can grab the files I used here:
http://www.mediafire.com/?dr6bqau194389te
Just UnZip the files directly to the root of the boot partition you created above (make sure flashing_boot.img, u-boot.bin, and boot.img are on the root not the folder SDCARD)
3. Insert SDCARD into NT
Now, with your NT powered off, eject the SDCARD you just created from your computer and insert it into the tablet. Then just turn it on and VOLA! You should now be in CWM!
Symptoms:
With the SDcard (from above) inserted and the NT powered on, the NT shows a black screen for about 3 minutes, and then boots the internal memory.
Removing MLO from the SDcard causes normal NT internal memory booting, so clearly the NT boot process is looking at the correct place on the SDcard (note that the MLO for 1.4.0 and 1.4.1 are identical).
So, unless I am doing something really stupid, there's something different between the two NTs I've owned. Note that "bauwks" had a problem booting from the SDcard, unless he had the USB cable connected, but others have not seen that symptom.
I rooted my NT 16GB by following this post and it worked well:

thamks for the rely but ive tried that already
So you wrote all the files you unzipped from the download to the sdcsrd, inserted the SD into your Nook and rebooted...do you get the box when you reboot?
Just checking, you're holding down both the power button and "n" button when powering on the tablet?

This is too complicated, really.
Just got a used NT16. Previous owner factory restored. Downloaded img file from:
[SD Root] Make 16 or 8GB Nook Tablet Root SD Cards by Albert Wertz [SDNT16or8gbV4.7]
No instructions on how to mount image to SD card for Mac (it says just google it...)
Google did not turn up a clear result.
So I finally Googled the right query: how to burn an ISO on a USB drive on Mac OS X
And in turn gave me this - how to mount the image:
"Directly from the Ubuntu download page (my formatting):
Download the desired file
Open the Terminal (in /Applications/Utilities/ or query Terminal in Spotlight)
Convert the .iso file to .img using the convert option of hdiutil (e.g., hdiutil convert -format UDRW -o ~/path/to/target.img ~/path/to/ubuntu.iso)
Note: OS X tends to put the .dmg ending on the output file automatically. Remove the .dmg extension as necessary, mv ~/path/to/target.img{.dmg,}
Run diskutil list to get the current list of devices
Insert your flash media
Run diskutil list again and determine the device node assigned to your flash media (e.g. /dev/disk2)
Run diskutil unmountDisk /dev/diskN (replace N with the disk number from the last command; in the previous example, N would be 2)
Execute sudo dd if=/path/to/downloaded.img of=/dev/rdiskN bs=1m (replace /path/to/downloaded.img with the path where the image file is located; for example, ./ubuntu.img or ./ubuntu.dmg).
Using /dev/rdisk instead of /dev/disk may be faster.
If you see the error dd: Invalid number '1m', you are using GNU dd. Use the same command but replace bs=1m with bs=1M.
If you see the error dd: /dev/diskN: Resource busy, make sure the disk is not in use. Start the 'Disk Utility.app' and unmount (don't eject) the drive.
Run diskutil eject /dev/diskN and remove your flash media when the command completes
Restart your Mac and press Alt while the Mac is restarting to choose the USB stick"
So.........
I followed the instructions to a tee. I am using a 128 MB SanDisk micro SD card.
I inserted the card in my Nook and powered it off. Put the USB cable in and after many minutes the Nook turned on. All it did was power on like normal. Once, I removed the SD card while nothing was happening (waiting for boot). Intermittently (as a result?), I was unable to turn Nook on at all, thinking it was bricked. So, I tried the SD card again, and again after several minutes it turned on. Have removed the card now and Nook works like normal again.
So, I have a 16GB Nook Tablet with 1.4.3 and would like to root it AND flash Android which may require who knows how many sd cards and various recovery modules. I would like to say I love learning how to do all of this, except these instructions are always written by developers FOR developers. Perfect example is the Bishop of Technology. One page leads to another and then another. There is no definitive answer to be found on his site. My favorite part is where he says "now take out the boot card and insert ("vague") custom ROM. And then says, now you might want to backup (using CWM). This is all on the page for installing Jellybean on 1.4.3. The whole page is a mish-mash of vagueness and redirection. That is why I tried installing directly from XDA instead.
But, like I said, I was unsuccessful. And I'm not willing to risk trial and error or spend another four hours digging around trying to find the meaning of every instruction. How hard is it to go into a bit more detail and include links every time appropriate. (insert custom ROM - this is vague and no link is shown for downloading the custom ROM.)
Should I get a 2GB sd card so I can install 142 (500MB) first?
Maybe rdisk was to fast and corrupted the image?
Maybe try this. http://forum.xda-developers.com/showthread.php?t=1494367

I have an iBall Slide i701 running Windows 10. So, I wanted to try RemixOS on my tablet after seeing a thread on some site. So, I downloaded the zip and tried to use the USB option but my USB was not detected at all. I tried everything like formatting the pendrive to different formats, but still no luck. Then, I tried the Hard Disk installation, but here's the problem. My tablet has 16GB of internal storage of which right now about 7GB is free (which isn't enough to repartition). But, I do have a 16GB SD Card on the tablet but it's being shown as Secure SD Storage and I am unable to create a normal bootable partition with the SD Card. So, when I try the hard disk installation option, the SD Card doesn't show up among the hard drives, instead it shows among USB. Anyways, I tried USB installation to the SD Card, but it won't boot into the USB though I have set UEFI as boot option #1 and disabled secure boot.
Please help me out!
Well i have tried everything from booting linux to win7 win 8.1 installers with and without efi installers it just doesn't boot from any flash drive. There is a lock in the bios on boot option that forces it to boot from internal and yes i also tried via its sd slot, the prob is the sd card can only be accessed after it boots up, so thats a bummer,

hello, ive had similar problems with the iball marvel 6 and ive contacted iball for it and they sent me this email
With reference to your below mail, iBall compbook Marvel 6 comes with pre-installed OS 64 bit Windows 10 Home Ver. Customer cannot Upgrade or downgrade the OS through online or with any other external devices. Compbook works on tablet technology it will not support any other OS except the OS which is preinstalled in it, therefore there is no any separate drivers available for that..
i dont know if this is similar to yours but your slide also works on tablet technology so it might be the crux of the problem.
It is possible to load from USB
I had the same problem with my iball i701, during win10 upgrade it went into blank screen of death. Heres what i did.
0. Make efi shell as first boot in bios.
1. Go into efi shell, type map. It lists the drives, usb is not listed.
2. Unplug usb, type map -r
3. Plug in usb drive (my usb was win10 efi bootable drive), type map -r
4. Voila now the last entry is usb drive.
5. Type reset, press esc to go into bios. Usb is now listed in boot options.
Done.
Hello, I rooted my ICOO iCou D70G2 and managed to softbrick it into a loop at the Android messages. I bought another, identical tablet, and would now like to clone the new one into the old. I would very much appreciate complete, newbie level instructions on how this can be done.
Here is what I have tried so far.
I looked for a stock ROM for this device, but can't find one. The closest out there I could locate is for a D70Pro II. I don't know if it will work, and in any case, I still can't figure out how to flash the old tablet.
The old tablet does go into recovery mode using vol up and power. I tried putting the Pro II flash on the micro sd card (tried both img and zip, separate times), but the tablet isn't seeing the micro sd card in recovery mode with the update from sd card option. It shows a folder /sdcard with some seemingly empty subfolders, but even if I take out the micro sd card it shows the same set of folders and says choose a package.
I tried using the Intel USB drivers with adb, but the device isn't recognized in recovery mode by adb. Rockchip Batch Tools 1.8 also doesn't see the device, although it seems to load the ProII img file correctly.
It would be really great to get this old tablet to work. I don't have any CWM, TWRP or any other backup software on either device at this point. The new device is new from the box and not rooted.
I have this device that suddenly becomes read only the entire internal storage.
I can boot and use it but the apps, including the launcher3 crash every time that they are launched. Only "setting" app and some other apps that not write to storage can work
tried to get an adb shell on pc but can not debug with usb because there is no debug app selected on phone, i think that is needed write access to do that. Tried flashing stock rom with the procedure indicated by the devs of the app, but not worked (it worked a time ago), this device is rooted.
I can connect through usb and mount internal storage on pc and read the contents, but can not write.
Connectbot does not work, but i think if there is an way to launch a terminal inside the device, maybe i can change mount options of partition or change some other things to recovery the phone.
so someone knows how to execute and not install a terminal shell from sd card?
