Good morning-
I have a TF101 (with keyboard) running KatKiss 4.3.1_027 and gapps 4.3_20130914. Everything was fine until yesterday morning when I lost network connectivity and decided to reboot (this happens from time to time). Unfortunately, now my tablet won't boot. I get the splash screen with the swirling colored circles, but nothing more.
I tried booting to TWRP (v2.6.3.0 if it matters) and flashed KK and gapps again (including wipes as instructed). This time, it got to an "Upgrading Android" screen, went through my apps, but then got stuck on "Starting apps." I've given it about an hour in both situations and still nothing.
To make matters worse, my microSD slot is flaky and usually doesn't read my card. Based on what I've found, it looks like I have to use adb to push any new files to the tablet. If I boot TWRP and connect my TF to my PC (Windows 7), it tries to install "ASUS Android MTP Device" but is not successful (yellow exclamation point - "This device cannot start. (Code 10)"). I've tried downloading and installing the suite from ASUS, but that doesn't seem to help. "adb devices" doesn't list anything, so I'm stuck here as well.
Any help would be greatly appreciated. Thank you!!

Welcome to XDA!
This is what I responded to you over at TFF:
Sorry for the issues, it looks like the issue is a corrupt /data/ partition. By default "fsync" is off because this makes it faster, however it could get in a bootloop due to this speed. The fix is to flash the "fsync_on.zip" before the boot loop happens.
Once it happens, you are stuck, but there is help.
If you have TWRP 2.6.3.0, it is supposed to have USB support. Plug in a USB drive before booting to TWRP and it should be there.
To fix your issue and lose very minimal data, here is what will need to be done:
Boot to TWRP.
Backup only the /data/ partition. I would back it up to USB if possible, or if not back it up to the internal or microSD (if the microSD is playing nice).
Next (here is the leap of faith) do the wipe of the SYSTEM, CACHE, DAVLIK and DATA partitions. Do not do a FORMAT DATA, just a WIPE DATA (in the advanced section of the WIPE menu).
Now, install KatKiss and the GAPPS.
Wipe CACHE & DAVLIK.
Reboot.
Sign in to your Google account. You can have it restore apps if you want, I usually do myself, but it does not really matter.
Once it is done restoring your apps (or if you choose not to restore) open the Play Store an install Titanium Backup and the Premium Key for TiBu. You need the premium to restore from a TWRP backup.
Open TiBu and go into the Menu section, then find the option to restore from a nandroid backup. This will scan for any nandroid backups. Pick the backup to restore from and it will take a few minutes to scan the backup. Pick the apps you want to restore data and / or the app from.
Go make a coffee and wait for it to complete.
You may lose data from one or two apps, but you will have it from the rest of them. That is better than nothing.
Thank you!!
If that's all it is, then it's not as bad as I thought.

Unfortunately, this doesn't seem to be working for me. I used TWRP to power off my tablet. Then, I plugged in a USB stick into one of the ports on my keyboard, as this is the only way that I have access to a port. TWRP boots as expected, but I can't see my USB device anywhere. Am I doing something wrong? Is there a partition on the internal storage that I can use for the backup that won't get wiped by the process you outlined above?
Thanks again!!
You can use the INTERNAL storage option, just be sure that when you wipe you only wipe the DATA partition. Do not choose to FORMAT DATA.
WIPE DATA = wipes the /data/ partition without wiping /data/media/ (which is the /sdcard/ directory or INTERNAL)
FORMAT DATA = formats the entire /data/ partition.
As I said above, you can use the internal storage option but be sure to only use the wipe data option.

Just so I'm 100% clear:
Boot to TWRP
Check only "Data" from the left menu.
On the right side, "Storage: Internal Storage" is selected and nothing needs to be changed here.
Swipe to back up
Proceed with the steps in your original post.
Correct.

Success!! Thank you! Thank you! Thank you!! Two follow-ups to this:
1.) Since I was never able to get this working, is there a way to access the USB/SD card slots on the keyboard dock in TWRP? Using the internal storage is good, but if I want to wipe the whole thing (since my microSD card slot doesn't work), I would really have no way of ever being able to do this.
2.) I actually went up to 4.4.2, mostly because I could. However, I seem to have issues with the Google Play store where apps are always stuck on "Installing..." then the get installed but not really. I think I'll go back down to 4.3 unless there's a way to solve this.
Thank you again!!

Okay I am super confused. I've successfully used FORMAT utility and also nvflash restore...but the tablet won't format!!! All my apps and settings are still there when I nvflash restore it!
I ran the nvflash_gtablet.bat from the Format utility..and it looked liked it worked: at the end of the process the tablet showed the red font with the kernel mismatch and bootloader not found, or something along those lines..
Just to be safe, I did it a second time. lol
Then I used nvflash restore to restore it back to original shipping.
I noticed right away something was wrong when as soon as it booted to the tap and tap home screen, the screen started to go dim after 15 seconds (that was the screen timeout time I'd set before formatting and all that).
But I thought maybe it was a fluke, so I checked the app drawer, and all my apps are there!!!! Not only that, it connected to my password protected wifi right away!!
Can someone please help me delete the f_ck out of this thing? I want there to be NOTHING left, so I can get a clean start.
The reason I wanted to format is because, I'm having a sound issue with my gtablet (whenever entering the volume control and adjusting the volume the processes always force closes...no matter what ROM I'm on). I wipe data, try to start fresh, but the problem always occurs after a few hours of use on any ROM (even the brand new TNT 5).
And I don't know if this matters or not, I'm on Windows 7, 64 bit...but I obviously have the USB drivers working because I'm using these utilities.
Please somebody? Today is my only day off work for a long long time.
I "THINK" I remember reading that you could flash CWM and from there wipe user data, then run nvflash to get back to stock recovery. Never tried it myself & I'm new here, so take the info for what it is worth.
Don't panic....
I don't think you have anything to worry about. If you read the post (http://forum.xda-developers.com/showthread.php?t=974422), it states in rather large red letters at top :"This fully erases the ROM but this will NOT affect the internal SD card. You MUST be able to use nvflash to restore the stock firmware."
Since your apps are installed on the internal SD, that's why you see them when you reload the ROM.
Edit: If I were you, I'd run the Format and load stock, then reload Clockwork and format the internal SD. That should get you back to a rather vanilla slate.
You can also refer to the posting below as another source. If you go down to the Homebrew link found in the posting, it's is used to revert the gtab back to it's original TnT state.

Thank you all for your replies. But I am a little confused still. AFAIK the apps aren't on the sd card...wouldn't I be able to see them when I mount the sd card on the computer?
ksc6000,
Storage devices on the G-Tablet are named as follows:
/sdcard -- main memory
/sdcard2 -- external mini-SD card
/usbdisk -- USB key
Rev
Non-critical, just an observation that I am looking for additional information on.
I purchased a 32g S3 phone from someone that already updated to CM10.2. It looked like the seller reset something (no apps, data, phone started in initial setup mode), but there was obviously a lot of trash left over on internal storage that I wanted to clear away.
After clearing everything away, and downloading several apps to help remove more, I found that the internal storage was still >50% utilized. Even digging around in the root file system, I was still at a loss to figure out where more than 12gb was being consumed.
I tried a factory reset in clockworkmod, clear cache, etc. I did not dive into formatting partitions. On restart, I still see >50% consumed space and temp folders left around in the user data /sdcard area.
Out of curiosity I tried the factory reset from the CM10 system menu. After rebooting phone, it seems like all storage was properly cleaned up with about 26gb of 32g free; significant improvement.
So, there is clearly something different between a CWM factory reset and a CM10 factory reset. For the latter, it looks like the whole user-data area was formatted and repopulated with necessary folders/files. I suspect my “lost” space was somewhere in root….
I am just curious to know what more the CM10 system factory reset is doing above what the bootloader is trying to do.
Thanks!
When you do a Factory Reset in recovery (I use TWRP so it may be phrased different in CWM) it is intentional that this option does not wipe /sdcard (internal storage). You have to choose to wipe internal storage (in TWRP it's called Formatting data") by going into that Format menu to wipe all of your data from the phone. If a factory reset wiped internal storage, then there would be an incredible amount of angry people who lost important files like pics and videos. The option is there in custom recovery, it's just buried so that when you find it, you intend to use it on purpose and not by accident.
Edit: Factory reset is literally clearing cache, dalvik cache, and the rom from your phone. If you boot it up without installing a rom then your phone won't do anything cuz it's without an OS.

And the 'system' partition in 'data'.
But all that other crap apps plunk on your internal memory remains, unless you do a 'system wipe' from TWRP or CWM. But that will delete everything on the internal memory. That's what I'd do if I were giving my device away... though I tend to just Odin/RSD/CAB back to stock (depending on the device) for best results.
Hey all,
I did a "factory reset / wipe all data" from within the CWM bootloader. However, there's still a load of trash remaining within the folder /sdcard, like movies, pictures and remnants of games I had installed. I figured that the reset wiped the system folder, but not the sdcard folder. This is correct?
Anyway, my question would be, how do I do a total wipe? I also want my /sdcard back to factory settings, how do I go about this?
Thanks in advance,
Noah.
PS. Some background info: I'm on rooted lollipop 5.0.1, using minimal adb and fastboot and CWM as bootloader. I've got some vague idea of what I'm doing, but mostly I just follow instructions on this forum blindly.
I did a reset because I had a bootloop at the nvidia logo. This followed after the battery got down to 1%, at wich point all kind of processes stopped by themselves. I plugged the shield and after battery was full again rebooted, yet it didn't.
Try in Settings, Backup & reset, Factora data reset.

In CWM, go to Mounts and Storage Menu and format /Data and /data/media. It'll erase the internal storage.

Perfect! That did the job. Thanks for responding
My K1 has been stock rooted for awhile now, and this past weekend I decided to flash a rom on it. I downloaded everything and went into TWRP to start wiping per instructions.
In my haste I selected to wipe EVERYTHING! Internal, SD, cache- the whole works. Abbot the time the wipe finished, I thought "Oh no, I did not leave anything on there to give the tablet instructions!" No new ROM, no old one either.
I have left it in TWRP since Saturday, afraid to reboot it. I fear it will permanently brick because there isn't anything on there. It is still in TWRP, plugged in.
I tried using am OTG flash drive but TWRP does not see it. I took the SD card out & loaded the new ROM on it, but TWRP does not see it either.
I am using a Linux Mint terminal with ADB commands to do this. Sudo ADB devices sees it, shows the serial #, and says Recovery.
How do I get a ROM on this device and get it functional again? Can I reboot it? To bootloader, or to recovery again? What is my next step?
I am an amateur with Linux, so please, keep the commands simple!
Thank you!
Don't worry it's not broken. Just put your SD card in and mount it (click mount and check usb otg or sd card or whichever media you're using) and you should be able to see your media when you click install and expand devices.
You can also connect your tablet to your pc and simply drag and drop files into its internal storage, your linux pc should be able to see your shield if it's in twrp. Just open nemo (win+E) and place the files you want to flash. Just make sure if you're transfering files from linux to give it a few more minutes after transferimg before unmounting your tablet and starting to flash.
I LOVE YOU, MAN!!! I tried mounting (had not seen that in TWRP before) the SD card, but it still did not see it. I put the OTG drive back in and mounted, it saw it! I proceeded to flash the rom. I had a hard time installing gapps, I am going to reinstall it tomorrow.
Thank you, thank you, thank you for your help!

No problem
Make sure you've downloaded ARM and not ARM64 gapps for your android version (7.1.1 or 8.1 depending which ROM you use, you can find the version on the bottom of the first post).
I downloaded the link in the Rom post, but I will double check. Thanks again!

Maybe already lessons learned, but a couple points I often tell folks on these forums:
- The TWRP default WIPE option (which only wipes data, Dalvik and cache) says "this is the only wipe you need most of the time". It says that for good reason, and they mean it when they say that! This default works great for flashing ROMs. Some folks will swear by wiping "system" when flashing a ROM. But this is already done when you flash the ROM, so it really is redundant.
- The option to wipe other partitions (besides the default) is labeled "Advanced" and again, it is called that for good reason. My advice would be, to not wipe anything under this section, unless you know exactly what it is, and what the result will be. There are sometimes valid reasons to do so, such as you want to completely wipe internal storage, and start fresh (various ROMs and apps dump a lot of extraneous stuff there, that never gets cleaned up unless you do so by some manual means). But again, you need to be prepared, such as not having your backups or ROM (that you intend to flash) on the partitions you are about to wipe.
- If/when you do choose to use the Advanced wipe features, always double check (triple check, for that matter) what you are about to wipe. It is easy to click the wrong box, and there will not be any confirmation of what you are wiping once you swipe. It's easy (maybe too easy) to intend to wipe something harmless like cache, but accidentally tap SD card or internal storage.
@redpoint73- Believe it or not, I know that! I did want to wipe the SD Card, and the rest of the tablet, so i could get rid of everything old that was making it lag. Good thought, just not all at one time. Lesson learned!
Nothing was harmed, tablet is better, gained some Linux experience, so all around it was a win!
How I unbricked "Decryption unsuccessful" The password is correct but... (Apps2SD)
Hello, I don't usually post in tech forums, I usually the guy that only reads,
but this is the time when i could not find the straight answer to my problem and had to google the solution out of similar posts, so I decided to glue everything together and write my solution to this particular situation,
so I might save a lot of time to someone who got in exact or similar situation.
Sorry for my crappy English, but here we go.
What this post trying to solve:
You stuck at boot loop: "Decryption unsuccessful" The password that you entered is correct but unfortunately your data is corrupt.
and how to make it work Apps2SD with Huawei P9 SD card with enabled password protection.
Basically my Huawei P9 (EVA L-19) with Android 7.0 Nougat got running out of internal space, and i am really a heavy user on apps. Kirin 955 handles just fine as long as it has at least 10Gb of internal free space.
I have SD card 64Gb, but huawei stopped support, native move apps to SD, long time ago. My device is rooted, so I was searching for a solution. There is few apps that can transfer your internal memory apps to SD by using root, but the one that actually worked for me is Apps2SD. The thing is, my SD card is password protected (Huawei native function) I want to keep this function in case of device getting stolen.
Problem is, many third party apps that move your apps to SD, does not know anything about Huaweis SD card password feature. In fact (as far as i tested) only Huawei phone allows you to enter password and show contents of SD card, no PC, or for example Samsung phone will recognize this SD card.
So i was messing with Apps2SD, partitioned my SD card in to 2 primary partitions, 1- exfat, 2- Ext3. It works kinda fine, but after reboot, there is delay, Huawei unlocks SD card after main boot part, and Apps2SD does not understand this and show that it failed to mount second partition.
In this case, Apps2SD starts giving you solutions, one of them is this ADVANCED mounting option. It does not tells u about any dangers, nothing really.
I chose that option to see if it will be able to see second partition contents faster, rebooted - boom bricked.
You see the message: "Decryption unsuccessful" and asks you for decryption password. It might be SD card password, not sure, it does not matter, because you can type ANYTHING and it always say:
"The password that you entered is correct but unfortunately your data is corrupt". And gives you only option: fully data factory reset. Now hold your horses, dont press that. I just knew that this is bull**** and no way
my personal data is corrupted, its just some hadshake issue. (I was right i fully recovered everything up n running)
Assuming you got in this mess, your device must be rooted and you probably have TWRP recovery, cause Apps2SD work only with rooted devices.
To recover from "Decryption unsuccessful" boot message and restore all data and settings:
Got to TWRP recovery by holding power button and volume UP (after phone vibrates, hold both buttons 2sec more and then release power button, and then after 2sec more release volume up, cause if
you do this too fast, u will end up in wifi recovery by Huawei, and it wont work anyway cause your device rooted).
Then go to advanced and file manager, locate sdcard folder (this will be internal memory, not external), you should be able to see all of your personal files! Copy them to flash drive by connecting with OTG.
What we gonna do now is: do a full nandroid backup: TWRP, backup, check: BOOT, SYSTEM, DATA. and do a backup to flash drive connected with OTG or hard drive if it works for u.
After backup is done, go to WIPE, select format data, select DATA partition and see what original file system it uses. Now format in any other system, then reformat again to your original file system.
DATA partition somehow lost its encryption handshake key and this caused the problem, reformatting fixes it.
Now do a full wipe as if you would install new rom, wipe: system, data, storage, cache, dalvic cache.
Restore your previous nandroid backup, reboot to system,now your phone should boot with all the apps and settings just as you left.
You might be missing some pictures and other media in main storage, just connect your P9 with usb cable to pc, and restore previously backed up media from flash drive manually in pc interface (copy paste, replace all),
some small minority files might wont copy, don't worry about it, Im not sure but they are mostly indexing files, all ur media will be back in place.
Now, how to make Apps2SD work with this configuration?
Don't use that advanced method to find SD cards second partition, use any of first 3, the 3rd one worked for me just fine, cause its SU library based one.
Don't move your apps fully to SD, or they will "disappear", move everything except APK, ODEX, DEX (Lib is optional, you usually can move this one just fine). SO basically app core will stay in main storage but cache and app data will be on second SD card. This way, after you reboot your phone, you will have to wait like 3mins and App2SD will link your files to apps itself just fine. It might will show some errors right after reboot, but after Huawei unlocks its card, files will be linked, and apps wont be "gone" cause app core still stays in main storage.
This way i managed to save a lot of space and move most of app storage to SD card, P9 became very responsive, even in 2018 this is a really fast smartphone.
Sorry for a messy post, I'm not a writer, but I hope this helps to someone!
Thanks a lot, you saved my phone-config! ) This step "...and see what original file system it uses. Now format in any other system, then reformat again to your original file system." was unclear to me, as TWRP didn't give me the option to choose a file system, but in the end it worked out fine without just as well.

How did you run into this issue?
If it was due to updating Magisk to v19.x (on Huawei with Nougat / EMUI 5)?
In that case, there is an easier solution, just flash back Boot img with Magisk v18 1 and everything will continue to work as it did (without any need to reformat, factory reset, etc), see

I'm not entirely sure what caused it, but I suspect Apps2SD just like in the original post (I installed/tried to use it shortly before the problem occured).
