This forum is the closest I could find for the ASUS MeMO Pad FHD 10. I have searched XDA and Google to no avail; if I missed something please let me know.
I am wondering if anybody knows how to re-partition/fix corrupted internal memory (guessing that this is the problem). I am able to boot the tablet into recovery mode (fastboot). 'fastboot devices' shows the tablet is connected. I do a full erase (cache, system, -w). I then try to 'fastboot update' with the ASUS stock OTA file (US SKU). Everything goes fine until... 'cannot write file to /cache.'
I have tried 'fastboot format /cache' and 'fastboot format FS:YAFFS2 /cache', but I get an error of 'cannot format filesystem of type , requested type YAFFS2'. Notice the big empty nothing after 'filesystem of type'. I am taking it to mean that either it is not recognizing the internal memory and so cannot format it or write to it, or the internal memory is corrupted somehow and needs to be reparted. However, since I cannot connect ADB, I don't know how I can run a shell and partition.
I contacted ASUS technical support and they suggested that I send it in for service and have them replace the motherboard (big surprise). I can't replace the internal memory since it's soldered to the PCB.
I looked on CWM and TWRP and neither one has this device listed. Should I try a recovery image for a "cousin" device like a Transformer? Or would that just end with me creating a singularity and destroying the world?
Did you ever fix it again? I think have the same problem.
Nope, no luck with it. I contacted ASUS technical support about replacing the system drive, but it is hard-wired to the board. Told the customer he was SOL.

Everyone,
I've written this a bunch of times but and putting it in
it's own thread so folks can read and use it.
Memory and Storage:
/sdcard -- internal memory of the tablet
/sdcard2 -- microSD card in the external slot
/usbdisk -- USB key slot
Stock Recovery Info:
Main method: Put your recovery folder and update.zip on /sdcard, turn off the tablet, the press power and volume + to initiate standard recovery.
Second method: Put your recovery folder and update.zip on a microSD card. Edit the command file in the recovery folder with Notepad to change the location from /sdcard to /sdcard2 and save it with the name "command" (NO
.txt or other file extension). Then boot recovery with power/volume + and the OS will use the sdcard (assuming you don't have a live recovery/update.zip file in /sdcard).
Third method: If you can boot recovery to CWM but can't get your ROM to work, go in recovery to the mount menu and go down to the mount USB memory option and choose it. Then plug your connector cable from the miniUSB port to your PC. When you plug into your PC an Explorer window should open and you should have a drive letter representing the G-Tablet (it's G: on mine) on your menu. You now can select that letter and you have access to your tablet memory (/sdcard). I've even had a time or two when not a single file showed!!! I added update.zip and recovery and loaded
a ROM!
The tablet boot process apparently checks /SDCARD. If it doesn't find a recovery file there it does the same check if you have a miniSD external card installed. The large USB slot is not useable for booting or recovery so far as I have determined or read.
I hope this helps you.

EDIT: I didn't put one fact in here about recovery that everyone should know. When you run a recovery operation, the system deletes the command file so you can't accidentally do it again. If you have to run a recovery or
attempt to load something again, make sure you have a command file in the recovery folder with the correct command in it!!! Sorry I omitted this first time around.

Hope everybody who needs this has seen it. I won't kick it up again.

Can you also add information about partitioning of /sdcard and why would one need it?
Is there another "hidden" flash memory available for firmware or all mods and custom ROMs go into /sdcard only?
Thanks so much, I thought I'm dead cuz I wiped out everything.
This may have been asked before, but how does one perform a full data wipe w/o using CWM? Thanks.

You need to use nvflash (nvidia tegra SoC flashing utility). There are alot of posts about it. Do be carefull if you go this route, as even though you will not damage your tablet, it may be difficult to put it back to a bootable state if you don't do it properly.
thanks!
thanks great. simple and to the point. should help people that get confused. thanks again!
Vlad_z,
It has been my experience that when somebody gets boot loops, it often involves a
partition problem. Also, sometimes the G-Tablet does flaky things. I have one I
just shut down. Restarted it with boot looping and had to rebuild.
The three locations listed above are the three memory places you can store stuff
unless you find software that custom sets up something else.

That's kind of odd, my removable sd card ended up with the label ex-sd. Doesn't seem to be messing anything up though.
sixtofive,
I've never seen or heard of that with the stock ROM. Are you running a different ROM?
Some of them do change the directories.
Rev
So simply put, we should copy and backup the recovery folder and update.zip in /sdcard (or tablet storage) and when things get f'ed up, we move the recovery folder and update.zip back into the /sdcard?
Maybe it's just me, but I looked into the recovery that was already in the tablet and there's nothing in it; is that normal? If not, can anyone provide the back up recovery folder and update.zip just in case?
sam,
Recovery is simply a folder which holds a file named "command" in it. Command is a file
that has the command line in it with the command and parameters to "recover" or "load" files onto your G-Tablet.
Sometimes when your tablet gets messed up, you can still use recovery and are lucky. But sometimes the recovery partition gets damaged and then you have to look
for other ways to get in and fix things.

Many of us keep telling people there is a lot to learn here -- and Android doesn't have
all the stuff built into it Windows does. Nor is Android known for it's great documentation!
If everyone would read all the stickies at the start of the forums, it would provide
probably 80% of everything they need to know.

If OP also put links to stock ROMs, that would be great
interesting...even though I don't have a microSD card in mine /sdcard2 seems to be a valid directory within "root explorer"
what partition and memory structure should I be seeing on my brand new g-tablet? any suggestion on "mount" and "df" output?
Question, which is the best method or quicker to backup before attempting other rom installs?
Deleting CWM
How would one delete CWM so that the tablet can be returned?
Got my gtablet last evening. Seems there is a lot to learn.
thanks butchconner...
Thanks all the people who are contributing at xda. You are doing a wonderful job. In fact I bought this device because of you ( I think Viewsonic owes you guys a lot. At least they avoided a big loss because of you. )
Two questions:
1) Is it recommended to flash back to stock before changing roms?
2) Is there a link to the stock Rom files that I am missing?
Thanks
So this has been a burning question of mine for sometime:
Am I missing something or can you no longer mount your internal SD card while inside TWRP anymore? This may have been a feature that was removed a long time ago ( even my One [m7] was missing the option). But if it was removed, then why does the mount option still exist within TWRP.
What i really mean is, when i choose the mount option inside TWRP I used to be presented with an option to mount the SD card to my PC so that i could transfer files while still inside TWRP.
I found that I couldn't do it because I encrypted my device. I had to erase the whole thing and start over with an unencrypted device and now it mounts just fine. It's an issue with manufacturing that's hardwired into the device.
Basically, device encryption is jacked up.
I think there was a mention that the solution isn't easy to remedy, but a software fix is coming in a bit.

I did not encrypt my device, or at least I did not do it with my knowledge.
So i soft bricked my device while trying to install the latest 4.0.1 image. I tried hard wiping the device and wipe cache partion from Stock Recovery but didn't help, still wouldn't boot. I tried installing the image in Stock Recovery from Apply Update From External SD Card, but i got a few errors first "E:Failed to map file Operation aborted", i took a look at the file and it had about 1.67gb extra in "Userdata" i tried deleting that file and reinstalling from external sd card but then i got "E:footer is wrong" "E:signature verification failed" Operation Aborted.
Now i'm trying to install update from ADB (Surprisingly if i have the tab connected and im in Apply Update from ADB the tab is recognized in ADB
Code:
adb devices
serial # sideload and i have updated the drivers) But if i try to flash the recovery file 4.0.1 (provided from the developers site [cant post links]) "i just get waiting for device"
Anyone know how to get around this issue in ADB or properly install from external sd card without getting errors?
(Alternative read to my problem posted in the Nvidia Forums 98% sure i soft bricked my device [cant post links]
Did you ever find a fix? I'm having a similar problem.
Try to use fastboot restore everything.
I can't get it to connect to fastboot. When it loads the boot loader and I try to select fastboot protocol it fails.
Wow this thing sucks! I'm really appreciating my Samsung with Odin right now! So I finally got it to connect to fastboot (don't ask me how, I don't know) unlocked the bootloader and flashed twrp. Now it won't flash supersu in adb sideload so I put it on an SD card (which now magically mounts and works now) and flashed the zip in recovery but it says at the very end of the process while trying to update the partitions that it can't mount the data and system partitions so I'm not sure if I'm actually getting root or not and if so if it's permanent I have no way to tell. I think this is because they have been accidentally wiped. Do you think it is safe to try to flash a rom in recovery from external sd card? And if so which one? I have no idea which version bootloader, kernel, or os is or was on this device...
Update: I think I may start a new thread in the Q&A/Help section so that I can try to get a vast concensus. Thanks!

Yes flash a ROM in recovery.
Try Resurrection Remix. It'll resurrect your device
Just tried flashing bliss 6.2 and it won't get past the nvidia screen. It says it flashes successfully but I still get a bunch of "can't mount such and such partition" errors during the flash sequence. Not sure what to do, I can post pics if you guys want.
If you got/can get TWRP on there now, the advanced wipe menu will allow you to check /data for errors. As for /system, wipe it. If you get errors that e2fsck can't fix in your TWRP log, you'll have to put on your data recovery hat on. If it's that important to you, my advice is to adb pull the right file under /dev/block. You won't get a block device, you'll get an exact image of your data partition. Once it's fully pulled (it'll be 10 GB or more on a 16GB device), make a copy of it first thing, and use data recovery tools (testdisk, or if you really know what you're doing, debugfs). If you don't have anything valuable on /data (remember that any backups you took from recovery go in /data/media by default), just format that and be done with it.
Pray that there are no errors after you format everything, because that usually means your NAND is toast.
If your errors are hardware ones, you're royally screwed. Same thing happened to my Nexus 7 2013 model a year ago. Only way to use it is to flash a modified kernel that will use an attached USB drive exclusively as storage. If the NAND is toast inside the boot partiti,try replacing recovery, otherwise, you have to tether boot it (fastboot boot) every time you want to run it, unless you have the guts to try repartitioning the NAND (unlike on PCs, messing up there is an instabrick).
Since the Shield Tablet can use SD cards, you're better off. No USB drive needed.
So, being a noob. I tried to root my 1541 and ended up deleting the OS. I still have TWRP, which I believe means I am soft bricked. My PC (tried several different PCs) won't recognize the phone as a usb device. The bootloader screen always says "Connect USB data cable".
I have tried USB OTG, when I click "Select storage" it simply shows it as 0MB and wont open. Same for SD cards. Is there something super obvious I'm missing because I have researched this pretty well before asking for help. I've read all the guides, tried ubuntu etc.
I'm at the end of my rope. Any help would be very much appreciated.
Please describe exactly what you did (e.g which guide did you follow or what had you flashed etc.). And, is the system stuck at a static motorola logo (it's called bootlogo btw) or the stitching/globe animation looping over (this scenario is called bootloop)? I just wanna confirm how much of corruption has occurred and through which way, so I can suggest the easiest solution to try. Thanks.

Did you install the moto drivers on your pc?
Does your phone connect with different cables ? If you can get it connected in twrp choose wipe format data then reboot to recovery mount system from recovery run terminal command fstrim -v system fstrim -v data fstrim -v cache reboot to recovery now mount your phone and clean flash the rom
Hi all. Apologies for the wall of text, I have a few questions following all of the background below.
Device info: Samsung Galaxy S7 32GB running LineageOS 16.0, NOT rooted; SD Card in question is a 128GB Sandisk MicroSD. All commands being run on computer running Ubuntu 19.10.
Yesterday, my phone gave me the "SD Card Missing" notification suddenly, and in the settings it said it was corrupted. I had had it set up as adopted storage, so it isn't a matter of just losing photos and such unfortunately - it seems as though there's important app and system data on it.
After trying several recovery programs to no avail, I came across this thread:
https://forum.xda-developers.com/general/help/corrupted-sd-card-adoptable-storage-t3801250
Which is very similar to my situation. Unfortunately I didn't find a fix here, but I did manage to make a full .img copy of the card itself, and find the encryption key at "/data/misc/vold/expand_xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx.key" as per https://nelenkov.blogspot.com/2015/06/decrypting-android-m-adopted-storage.html . The problem I ran into with this guide was that I couldn't get the dmsetup command to work. However, when reading the comments of the post to see if anyone else had the problem, I saw someone mention retrieving the files through TWRP. So, I put the card back in the phone, and booted into TWRP.
In TWRP, I was able to browse through the SD Card perfectly normally with the file manager, despite the fact that it still read as corrupted when booting back into the system. So, I used adb pull (side question on this later) to retrieve the folders I was most worried about - largely what I could find of app data, my photos and videos, etc. I did not just pull the whole card at once, and I'll elaborate on why when I get to the side question about adb pull.
So, here are my questions:
1. Is it possible to mount this SD Card back to normal through TWRP? If so, how? I'd like just enough so that I can restore my apps as is onto the phone, and then convert the card to portable storage to avoid this mess again. While I do have the data pulled, it's little things like NewPipe playlists that I've got in mind here.
2. If above is not possible, how much loss am I looking at if I choose to 'forget' the adopted card? Will I have to do a factory reset?
3. (adb) When doing the adb pull, it was unable to skip any files it couldn't copy - i.e. corrupted images - and would simply stop on finding one. This means that, for example, in one folder it hit a corrupted file after 3400 successes, and stopped without copying the remaining 300. Naturally, if I had just done 'adb pull /external_sd/', then I probably would have lost a lot more because of this. Can I add any options to the command adb pull to circumvent this? I was unable to find any decent documentation on the command, but maybe I was searching for the wrong thing.
Any and all help is much appreciated, thanks in advance!
