Please Help Stuck In clockwork

Hi,
I was hoping i may be able to get some help , basicly i wiped my phone as normal to install rom as per normal , however the rom i copyed to internal memory must have been corrupted as it will not install "cant open /sdcard/rom/etc.zip etc"
Normaly i would just mount usb storage in clockwork to access internal storage and copy rom to phone. But clockwork doesent allow me to do this , how else can i access internal storage to copy new rom to phone ? Please not ive tryed searching forum but only solution it would seem i found was to flash back to stock which seems a bit crazy , is there any other way to copy to internal memory ....
** nvm moderator can delete post , sorted thanks to the awesome galaxy nexus toolkit restored to stock and rooted again in less then 10 mins

SD card LGoptimus G F180K disappeared

Hallo,
I'm really unlucky with this phone... My SD Card (internal) is disapperared and the phone says search sdcard or sd card is not installed.
With mount I can see something , /data is 25GB, but I can't root the phone and the folder /data is set with permission d--------, so I can't access it.
OK, I don't have CVM. Is there a way to re-format, change permission in the filesystem so I can re-flash?
Thanks

Update. I flashed JB stock korean 4.1.2 (F180K20B/G) and with JB I can see my sd card again, but the new error is "process "com.android.... stops to working" or similar.
It si a tipical Google problem. Has anyone the same error?
Thanks
Do the data wipe.
Flashing via KDZ doesnt wipe data
Thanks, but wipe doesn't work.
The problem is that the rom E97510B try to mount the sdcard in another path. But without sdcard you can't root the phone and you don't be able to correct it.
I reverted the phone to korean rom F180K10H and everything is fine.

(q) HELP PLEASE ! can't mount data on XPERIA S !!

HELLO, and thanks for reading me, so today i made the jump and wanted to upgrade stock rom of my xperia S, to the marshmallow rom via rtwp.
so i unlocked the bootloader proprely,but while merging the partitions 14 and 15 to increase the volume, i think something went wrong, after that i managed to continue the process and pushed the rom, i even got the loading screen witch ended ( of course ) by "encryption unsuccessful" and looploading.
inside the twrp i see that the sd card is 0 mb and cannot be accessed or wiped or formatted, i always have lot of errors :
cant't mount /data ( no such device ).
unable to mount storage.
unable to wipe /sdcard.
unable te recreate and sec-folder.
i tried many tricks but nothing is happening, so i flashed again to rtwp and its loopbooting to it, even the rom is lost and adb shell doesnt recognize the device.
fastboot is actually the only thing have access to.
please i need help, i'm desperate !

Do you know about adb sideload?it can help you in this case.
Check your partition if you merged p14 n 15 correctly or not.
Convert data and cache to ext4 and again return to f2fs.
without merging p14 and p15 the marshmallow rom can boot but you can only use 2 gb as data.
The MM requires
System as ext4
cache and data as f2fs.
so check if you done this.
ok, just figured out where the error was after merging the 2 partitions i skipped the last step after writing partition
mkfs.f2fs -r 16384 /dev/block/mmcblk0p14
that's because i followed another tutorial rather than xda ! so basically MY FALT !
but to restore my phone the only method that worked is to use flashtool and go back with original tft !!
after following the "right" tutorail everything went fine ! and i have a mooth brand new phone on marshmallow :laugh:

I encountered this issue more than once
The 1st time I managed to fix it by Emma the xperia official flashtool and returned to stock
The 2nd time I just flashed doomlord. Kernel with CWM booted to cwm wiped data and internal and then reflashed twrp and all was good with our errors..
I think it's something with twrp having trouble updating to the new partition table. I hope this works for u
I have the same problem, and after recovering to stock with emma I still cant see my SD card, not even on the computer. No internal storage for my Xperia S, it shows its empty.
What to do?
Hello I encounter the same problem while I try to flash to 7.1.2 from 6.0 . Sd card is 0 mb. Is there anyway to fix this ? I cant even flash stock rom any more uploaded some

Root Guide for 7.0?

Hello,
I have attempted to install twrp - (newest available version for ether) and it installs and boots, but twrp does not see the internal storage. I can't install SU because I can't see the storage.
Does anyone have a root guide for 7.0 on the ether? Or any idea what I am doing wrong?
I have searched and can't seem to find any discussion regarding root for the 7.0 release.

It doesn't see internal because it's ENCRYPTED. You need to format data then sideload either SuperSu or Magisk. Note: this will wipe internal storage and reset the device. The root method for 6.0 is literally the same for 7.0 on the Robin.
Flashing SuperSu or Magisk will disable the forced encryption. The reason you have to format data is to reset the partition and remove the encryption on the partition.

data encrypted and ROM not getting installed

Hi,
Short story short.
My twrp recovery is not able to install the lineage OS ROM. Initially no storage was getting mount and i tried few steps as per XDA's other threads.
Now still when i try to format my phone and re-installing the new OS the error comes that the Data is encrypted .
I tried some tips as per people's suggestion but still the problem persists.
Scenario: 1. no OS is there in my phone. 2. Cant access it via ADB as it doesn't read my phone.(i can access my internal storage now - previously couldn't)
3. OTG/SD card shows 0 MB even after trying all the methods( unable to mount storage error)
What shall i do as i need a working phone and no OS is present in it.
A help is strongly required. Thanks in Advance.
You need to format data from recovery, and then you an try again. Eventually have a look here https://forum.xda-developers.com/lenovo-p2/how-to/how-to-unbrick-phone-decrypt-flash-t3866270
