Fastboot's Wipe Cache Partition very slow on 6.0?

Like the title says, it takes about 5 - 10 minutes to perform a wipe from Recovery, where in Lollipop and before, it was a few seconds. A couple of websites have corroborated this.

Does anyone know what's changed in 6.0 that a cache wipe takes so long? I'm on an unrooted N5 and performed a clean factory flash (and re-locked the bootloader).

Did we go from

Code:

---

mkfs -t ext4 /dev/[device]

---

to

Code:

---

rm -rf /cache/*

---

or something? I mean, even formatting a heavily encrypted partition shouldn't take that long (especially one as small as /cache).

Anyone?

TWRP unable to mount cache

Hello,

I'm trying to preform a factory reset, however it always fails with TWRP unable to mount the cache. I'm running TWRP 2.7.1.0 and the Hyperdrive rom. The tablet is stuck booting now as well.

Does anyone know what might be the case?

unable to mount the Internal Storage, system, cache and data.

hello'
1- LG L3 stack on logo even after recovery.

I managed to install TWRP through SRKTOLLS2.1.
When I try to install a ROM ZIP file I'm having post:
unable to mount the Internal Storage, system, cache and data.
ADB interface device I manage to see the folders and system files.
*/ SDCARD is empty and there is no file.
/BOOT is empty and there is no file
/cache & /data folders contain folders in the name of lost + found,
/dev contains several directories,
/etc contains files: fstab, mtab, recovery.fstab and to more,
and the other system folders'
I can explorer them via TWRP file manager a and see the contents of folders, copy files or move files.
TNX :good:

Urgent please!!! unable to enter fastboot after wipe partition cache and bot error..

Its been a month my phone sitting quite...

After updating to latest version i decided to wipe partition cache while on the process it showed erasing android bot then restarted and hung on asus logo for nearly an hour so i decided there is some problem and force switched off then after switching on it shows the blinking android error bot.........im unable to enter neither recovery mode nor fastboot mode(when entering it shows for a some seconds waiting fastboot cmd bt then comes again to the normal boot screen)....
Its been nearly a week i went thru various post and tried most of the methods like entering recovery mode thru adb(as im unable to enter fastboot mode it shows in cmd waiting for device) and pressing both buttons same for stock recovery(it shows some lines saying in last line can't mount recovery)
SO CAN SOMEBODY THROW LIGHT ON WHAT EXACTLY NEEDS TO BE DONE TO RECOVER MY PHONE FROM THIS ERROR.... would be grateful and thanks in advance.

Why is the download cache at 4gbs?

This happens on my Tab S as well - never happened till Lollipop. Is there anything I can do to prevent this from happening? On my tab I use Clean Master. On my Note 4, I'm just clearing the cache through App settings
