[Q] Help! Think I bricked my TF101!

I have one of the newer TF101's (B90). I had the Revolver ROM installed on it. I encrypted the tablet. I attempted to install the stock ROM back on the device, which also wiped out CWM and reinstalled the stock recovery. Here's the thing: The original password I had does not work on the device anymore, and the tablet is seemingly still encrypted. I cannot boot into UPX (probably due to the HW version), and the recovery ROM only displays the ! graphic.
Is there anything I can do?

You need to wipe the data partition. This isn't windows. This is android. In windows, you have 1 big partition so reinstalling the OS kills everything. In android, there are over a dozen different partitions. Installing a new OS doesn't touch the data partition. And since revolver is based on the stock, some data will still work in the stock, like your encryption.
You need to nvflash in the cwm and use it to wipe the data.

but he has a B90 so no NVFlash

Oh, didn't see that part.
I am constantly amazed at people refusing (for religious reason or whatever reason) to wipe data before flashing another rom and then complain that something is wrong.
Someone else might be able to help. In the mean time, let me think about this one.

You can follow the Unroot Process, which will wipe /Data (also your /SDCARD) - you're already through the first part since you have the stock recovery installed.
Just download the stock firmware from Asus' website and follow the instructions in the "Updated Version of SOP" manual (also from Asus' website) - it involves using an micro-sd card and extracting the stock firmware to it, then booting to Recovery. The stock recovery should automagically find the firmware update and flash it.
Edit: Edited for clarity, and added a link to the download's page - http://support.asus.com/Download.aspx?SLanguage=en&m=Eee+Pad+Transformer+TF101&p=20&s=16

hold vol down, wait until it asks about data wipe, press vol up, wait a few minutes while it does the datawipe

[Q] Random reboots/Bootloop - Logs attached

Hey everybody.
EDIT: Thanks to berndblb and all the others who replied, it works again like a charm.
I just got my Asus Transformer back from RMA because it wouldn't latch with the dock anymore.
Now I'm getting random reboots when the tablet boots up. Sometimes it makes it to the lockscreen, but in this case it freezes immediately.
I now tried reinstalling CM 10.0 and 10.1.2 after wipping all the data from the Tablet.
I then tried installing the cleanrom with the data2sdcard fix, but I have now the same problem as before.
Additional Infos:
Recovery: TWRP 2.5.0.0
Rom at the moment: CleanROM Inheritance 3.4.7 http://forum.xda-developers.com/showthread.php?t=2049274
Data2SD http://forum.xda-developers.com/showthread.php?t=1962507
Bootloader: 10.4.4.25-20131228
If you have any questions or need more logfiles don't hesitate to ask. Somehow I can't get logcat to work before it shutdowns, so I can only provide log which are stored on the filesystem. (I can access the shell within the recovery and push and pull files).
Thanks in advance for your help and for your time in which you read this text.

Maybe an old bootloader? Check the version displayed in the bootloader menu.

I've got the 10.4.4.25-20131228 Version, which is recommended to install CleanROM.

Try installing the bootloader recommended for the ROM you are trying to install.

Sorry if I wasn't clear enough. At the moment I am trying to install cleanrom, because I thought the problem was with cm.
But now as I do have the exact same problem with cleanrom as with cm I think it isn't the rom.

You can try to remove the External SD card and reboot without it. Please report back so we all know what is happening, thanks..

"Wiping all your data" means exactly what? Have you done a factory reset in TWRP? If yes, try formating your data partition.
Plus, you are trying to install an outdated rom that is no longer supported.
sbdags has moved on to CROMi-X, the JB 4.2.1 based rom for this tablet. Look for the thread in the development section.
Flash the bootloader/TWRP package from the first post, boot back into your old rom.
Then do a factory reset in TWRP which will wipe your data partition and flash the latest CROMi-X rom.

I'll try that. I wasn't sure if the newer Version supported the Data2SD Mod so I tried installing the older Version.
But I see now that it's supported.
@LetMeKnow
As I'm using the Data2SD Mod, I get the error message "Encryption unsuccessful".
Which means it's really installed on the SD-Card.
I also am able to start it up to the setup process, but before I can finish the setup, the tablet randomly reboots.

[Q] can't decrypt/format tablet

I'm currently running a encryptet samsung tab 10.2 P-5100 and want to decrypt/format the tablet.
I'm running cyanogenmod cm-10.2-20131224-NIGHTLY-p5100
I have tried the following and failed to decrypt:
pressed the reset to factory button in CM.
in CWM (ver 6.0.1.2) Wipe data\Factory.
in TWRP (ver 2.6.3.0) Wipe data\Factory.
odin+ stock rom.
the tablet still want the encryptet password before it starts up.
any one have an idea what to try next.

On what ROM you encrypted the tab? Why don't you know your password?

I do know the password, but i can't decrypt the tablet. I want a tablet without encryption. the rom was CM 10.2 night but I don't know the version.

Encryption

A few questions about encryption on the S7:
Some threads, e.g., TWRP, refer to "Samsung encryption". Does the S7 use some sort of proprietary Samsung encryption, or does it use the standard Android encryption?
Since I have now disabled encryption after installing TWRP, can I re-enable it? If so, how?
Would FlashFire allow me to flash ROMs with encryption still enabled?
Thanks in advance.

1. Simply put, the method in which Samsung decrypts encrypted data isn't known
2. You can enable encryption but you must start from scratch. (As far as I am aware anyways). Means you must flash stock ROM in ODIN.
3. Not sure. You can certainly flash zips that modify /system. You can also use TWRP as long as you don't need to mount data. Switching ROM normally means a standard factory reset but if you are encrypted you can't use TWRP to factory reset and I am not sure if FlashFire can do it either.

2. do you have to really start from the scratch?
http://forum.xda-developers.com/galaxy-s7/how-to/how-to-encrypt-device-custom-rom-knox-1-t3392301
3. is factory reset not just a kind of a wipe? why cant twrp just format the encrypted partitions?
I spent also several days to fully customize my S7 (cfw S7 debloated) and i am quite happy yet.
But if I lost once a phone long time ago.. So encryption is a must, root too.
I would accept definetely a non-working TWRP, if I could get an encryption?
any advices?
thx.

Yep, once you disable encryption in TWRP and flash the dm-verity zip, the option to encrypt the phone won't even be available in settings. In the rare case that it is, it will always fail.
Since you want root and encryption, it is pretty simple.
Flash stock rom in ODIN (Backup, backup, backup anything valuable)
Obtain root using CF-Auto Root method
Install TWRP, allow modifications, don't wipe /data
You can only flash zips from external SD card. Internal storage will be unavailable in TWRP

I did a make backups with TWRP and TitaniumBackup.
May I ask some more questions, i do want to understand the procedure.

I guess the stock ROM is already encrypted - is that the reason why TWRP doesnt have access to /data (as well to the internal /sdcard) till the encryption is disabled?

After flashing stock the bootloader is locked again, so I do have to unlock the "OEM unlock" per developer settings again? The phone wont be wiped afterwards?

May i recover/restore here a formerly per TWRP backuped ROM? I guess, this want be possible, hence TWRP doesnt has access to /data, nor to /sdcard?!
Which partitions I am allowed to restore, respectively is there a chance to recovery somehow the TWRP backup (it was soo much work).
Or can i disable encryption and enable it again, after restore?

Once you flash the stock ROM, the phone is encrypted before first boot
Once you OEM Unlock, it stays that way unless you attempt to re-lock it. Once you flash a stock ROM and go to developer settings, you'll see OEM Unlock is still on
Encrypted device = No restoring of any kind in TWRP, that is the trade off. Some people use FlashFire to back up and restore. I tried once a while back and it didn't work. Others seem to be ok
If external sd is encrypted also, then your only chance is to use FlashFire. TWRP is basically useless

Thx for your reply
After I flashed stock and finally customized my installation, would this be safety feature to relock the OEM? Is a relocking wiping also the whole phone or only the unlocking?
So that means, that if go through this instructeres, i cant flash any CFW, neither i cant restore my TWRP backup?
Thats a pitty.

If you try to relock OEM, your device won't boot lol. I learned that the hard way months ago. Had to start from scratch.
What custom firmware are you trying to flash? If you mean custom ROMs then theoretically speaking you should be able to flash them using FlashFire.

Thank you for the hint - this will me spare the fate
I chose S7_extreme_debloated from @Battlehero.
I am quite happy with that CFW and i thought, i can install my apps and customize the system and start the encryption - didnt worked.
So, I will begin from the scratch too. It would be great, if I could start with this CFW after, flashing stock.

Best way to unroot and factory reset my Samsung Galaxy Note 4?

My problem is very simple at its core and I find myself resorting to extreme solutions such as factory reset to solve it. However, I am okay with this. I would like to know the best way to unroot and factory reset my Note 4 SM-N910U.
What follows is the original story and my attempts to fix it. It's rather long, so if you would like to skip this section there is a tl;dr at the end.
Originally, I had found myself unable to login to the app Snapchat because they had gone to extreme lengths to lock out rooted users (an infamous fact on online discussions).
A popular solution for this would've been to install the Xposed Framework with RootCloak to hide Root from Snapchat - this is where my first problem came along.
My Android phone is encrypted.
This means that I could not use TWRP to flash the Xposed Framework zip (because TWRP for my device does not support encryption, thus could not read /data directory.)
I tried using FlashFire to skip recovery and got the same result - /data encrypted.
I tried to flash with CWM to see if it would support decryption of /data partition, but CWM isn't even compatible with my device.
At this point I was running out of things to try (I had been after this problem for about three days) and I decided to just kick the bucket, unroot and factory reset, because apparently the only way to undo data encryption on Android is to delete everything .
Apparently, even this would be a challenge. To factory reset a rooted device, you apparently need a stock ROM.
I tried looking for stock ROMs for SM-N910U online but the sites that came up (there were about 9 hits on Google for my baseband) all seemed fake and potentially harmful.
Even then, I don't know how I would flash the ROM since my TWRP doesn't work but that's the least of my worries at the moment .
I'd be extremely grateful if anyone could offer any potential pointers on where to download a safe stock ROM for my device and how to flash this ROM when I have no working TWRP (since my /data partition is, again, encrypted).
It seems a bit like a paradox - to remove data encryption you need a TWRP stock flash, but for a TWRP stock flash you need to remove data encryption.
Please do help... thank you in advance.
TL;DR
- tried to install xposed to hide root.
- found out that i can't flash any roms from recovery, because my recovery (twrp) doesn't support android disk encryption.
- found out that to remove encryption, i need to factory reset.
- i can't factory reset, because I need a stock ROM and I don't know where to find said stock ROM.
- also, how would i even flash this rom without a working recovery (again, the recovery doesn't work because full disk encryption).

Go to Sammobile .com or samsung-updates .com this use your model number to search for your stock firmware, find the firmware for your region then flash that via Odin.
