Two issues: "Infinite Boot screen" and "Can't Mount /sdcard/" in Recovery Mode
Hi Guys I need some help,
So I rooted my tablet and installed CWM following this (I did not install CM), went ahead and rebooted the system, but it never actually boots, only displays the boot logo screen and never moves from there.
So I downloaded this rom and bootloader and pushed it to the tablet via ADB, then I go to Recovery Mode and try to flash it following the CWM menus, install zip -> choose zip from sdcard, then it tells me "E: Can't mount /sdcard/"
What should I do now? how can I fix the infinite boot screen and/or sdcard issue?
Thanks
Got everything back to normal.
Followed this to flash stock system/boot/recovery. Then flasehd TWRP and SuperSU to root the device
Hey so here goes. Stupid me went to perform a factory restore from within in android (stock 4.2.2 rooted) and I forgot that I had installed TWRP (currently 2.7.0.2) and when the tablet rebooted to wipe everything it booted to TWRP and tried to wipe where it promptly failed with "Unable to mount /data, /internal storage, /system, etc.
So here's where i'm at. The tablet will boot to recovery but will not let me wipe anything and will not boot to android.
When i attempt to restore a nand backup it will restore then error at the end with "Unable to mount /data" and again, the tablet will not boot.
I downloaded the TWRP 2.7.0.2 update zip and flashed over my existing recovery to see if that helped, no dice.
Now i'm trying to use the method found here on XDA to restore to factory using Download Mode and everything goes well until I get to the step where i actually flash the KDZ file I get this message:
Please install CSMG B2C Client TOOL.
Select Tool > B2C Client Setup Menu.
I have followed the instructions to the letter minus putting my tablet in USB debugging mode (can't boot the tablet, no Debugging Mode)
I have no idea where to go from here.
I should mention I also tried this on Windows 7 64 bit and Windows 8.1 Pro 64 bit.
Edit: I'm not sure what wizardry has happened but it finally worked! That was terrifying for a while there.

Hello guys,
I just installed TWRP onto my HTC 10. I unlocked the bootloader and flashed the recovery with TWRP. I backed up the default system and then wiped the Dalvik /ART Cache, the system partition, data partion and internal storage. As I now wanted to install LineageOS my device doesn't show up in the windows explorer. I tried rebooting the phone into recovery mode but it didn't work. So basically I can't accses my phone from my pc.
Can you give me some advice?

I booted into TWRP. I chose "wipe" and then selected "format data". The description of "format data" already says "will remove the encryption of your phone". So I formated my phone, insalled LineageOS and GApps and the system is running, no password needed.

So basically you wiped everything you could without knowing what you were actually wiping, and what wiping that stuff would actually do to your phone?
When you wipe the system partition you won't have an OS unless you flash a ROM directly after.
Place a ROM onto your extSD and put that into your phone. Boot to recovery and flash the ROM.
I'm aware of what a wipe does, but I wasn't prepared for this case. I flashed a couple Samsung Devices and after flashing them I still had access to the phone via my pc as long I was in recovery mode. But it seems to me, that I found the problem. The device is, as far as I know, encryped by default and a signal loss after wiping/flashing the device is common.

However, I managed to install LineageOS and GApps, and the system boots. But after the boot is completed I am facing a screen where I have to enter a password to unlock Android. And I dont know which password I have to enter.
Do you know how to continue?
Thanks for your help, I really apprechiate it.

Obviously you didn't exactly know, because if you did you would have known that wiping /system would leave you with no OS.
Not slagging you here. I did the exact same thing when I had just got my 2nd gen Nexus 7 and switched to TWRP from CWM for the first time.
For your password issue:
twrp > advanced > file manager > data > system ~ delete the locksettings.db files and reboot
Thank you for your reply!
Unfortunatley, the folder "data" doesn't contain any subfolder or file. Do you still know how to unlock my device?

Hello there. When i'm rebooting my phone into system, it's vibrating 2 times and model name appears (This loop always continuing). I can access to download mode and recovery mode. I tried installing stock rom via Odin it didn't install, loop continued. I installed CWM 6.0.5.1 but when i format factory reset, system or data it says completed successfully but when i enter into internal storage i can see (my pictures etc.) recovery didn't delete. Also when i'm trying to install custom rom (LineageOS 16) it gives (Status : 7 Error "no file_contexts target" ).
Any help would be greatly appreciated.
The so far...
Installed TWRP
Noticed I could not boot into factory ROM - TWRP boot loop?
Tried to factory reset from TWRP - failed; Data could not be mounted.
Changed the file system of Data to extf2; Repaired Data; Changed Data back to extf4
Factory Reset - completed
Still could not enter factory ROM - TWRP boot loop?
ADB sideload PixelExperience Custom ROM - allowed TRP to push app; boots into ROM to initial setup (G with progress bar) but doesn't advance after 15 minutes
Vol down + power -> Menu > Recovery
TWRP asks for password to decrypt data (**Edit - this is TWRP's initial screen after Logo)
*Edit* at no point in the life of this device (I bought it brand new) was it ever encrypted
At no point did I ever set a password or try to encrypt data. How do I fix this?

TWRP Asking for password. Please help. I've never set a password

Did not work.
Take a breathe...
In TWRP mount internal storage and select all toggles... Back to TWRP main menu select wipe / format data - type ´yes´
To wipe the rest go back to wipe / select all toggles and wipe it
Now you can flash like your way... If you want to sideload you must activate it in TWRP by Sideload /ADB... otherwise you can flash from external storage i.e. USB stick or whatever you want....
Format data partition is important to decrypt and wipe possible encryptions...
In future pls don´t change the data formats i.e. extf2 / exft4 or let repair them in TWRP in case you can´t handle it via ADB... TWRP is a nice tool but too many ppl bricked several devices by using this method or use unofficial shady versions...
If you try to flash PE you can push the rom on internal storage after fullwipe and after a recovery restart you can install it from internal storage...
I remember some strange TWRP times where we have to mount internal storage and partitions - and yes - before installing some stuff I´ve take a look on mounting points
