pretty sure this works, phone no longer says it is encrypted in settings, and i can browse internal storage in the TWRP file manager.
PREREQUISITES
This TWRP: https://forum.xda-developers.com/ho...p-ish-twrp-3-2-1-honor-9-running-gsi-t3818442
An 8.1/9 GSI
Unlocked Bootloader
HOW TO
Flash the TWRP from the linked thread in fastboot
Download the GSI of your choice and place its system image on LOCAL external storage (either a microSD or USB-OTG)
Boot to TWRP (if necessary change the language tfrom chinese to english in the settings)
select 'wipe' and 'advanced wipe', check Data, Dalvik, Internal Storage and Cache
Wipe!
Return to the main menu and select 'Install', Select 'Install Image' and browse to your GSI on external storage
Select your GSI, you will be asked to tell TWRP what its flashing, select 'System image' and flash
Return to the main menu and repeat the wiping step
Select 'Advanced' in the main menu and 'Fix DataEncryption', swipe to fix then reboot to system
You should now have an unencrypted device! (it worked for me)
I am not responsible if you brick your device, and a nuclear war starts because of it.
You WILL loose all of your data, so back up what you need first.

hi.
I have applied several custom ROMs and apparently each install overwrites previous but some folders remain the same.
It's there a way to make sure everything is cleared before installing a new ROM?
What about the format options in CWM?
I'm using nexness pro2 rom, installed with CWM.
THANX
Walter
There should be an option to wipe data in settings. This should have the desired effect.

There is indeed an option to Wipe Data/Factory reset, however this option doesn't seem to delete old folders in the sd card (even the internal storage /storage/sdcard0).
For example, if i have an application installed and it creates some folder in the root of the /storage/sdcard0, this folder will not be removed when I do a wipe. Does that make sense?
I've read that this is how it's meant to be, since some devices don't have an external SD card, so it would be hard to flash a new ROM if sdcard0 was wiped.
That being said, I would ask, is it safe to ADB into it, and then delete everything from there?
Is there any other "better" option to make sure I have a clean/fresh start?
Thanks.
Walter
You can try the hard reset code from the dialer *2767*3855# not sure if it works on the 7.7 though. You could painfully delete items with root explorer, just be sure they aren't being used by your current rom.

These are instructions from a post in the General section. They maybe helpful. Specifically, step six - if you research some of the older posts you find discussions regarding complete wipes.
How to Flash A Custom ROM-
Download a ROM of your choice from the All Things Root section (The Forum you are in) You can find direct links to each of them in the All Things Root Guide that is stickied at the top of this forum.
1- Once downloaded, its recommended to download it from your computer and place it on your phone, put it on the root of your internal or external sd cards. Root meaning not in a folder.
2- Reboot into recovery using Quick Reboot.
3- Using your volume keys to scroll and your power key to select, scroll down tand select "Wipe data/Factory Reset" then scroll to "Yes" and select.
4- Scroll down and select "Wipe Cache Partition" and then select "Yes"
5- Scroll down and select "Advanced" and select "Wipe Dalvik Cache" and then select "Yes" then scroll down and select "Go Back"
6- Sroll down and select "mounts and storage" then scroll down and select ONLY these 3 listed, "format data" and then select "Yes", then scroll down and select "format cache" and then select "Yes", then scroll down and select "format system" and then select "Yes". Then scroll down to and select "Go Back"
7- Then scroll down to "Install Zip From Sd", if you put the ROM on your external SD card select "choose zip from SD". If you put it on your internal scroll down and select 'choose zip from internal". Then after you selected one of those depended on where you put the ROM, scroll down and select the ROM and then Select "Yes".
the rest i am sure you have done before. Hope this helps.

i do the same steps enumerated above whenever i flash a new firmware. in addition to that i also wipe the internal sdcard to remove old folders/files.
take note that you need CWM to do that.
DON'T DO ANY FACTORY RESET/WIPE/FORMAT from SETTINGS/STOCK RECOVERYif you are using ICS because you risk frying your EMMC.
VERY FIRST AreaRom RELEASE for the ZTE-Z990 Phones!
THE AREAROM way to take your Z990 from Box-fresh to rooted n' rockin!
EASY 2 file method. 5 minutes, and your phone will be rooted, have a AreaRom Branded CWM installed, and latest 'under the hood' improvements.
ROM Features:
Based on latest GB release
Rooted! No need for adb or any other procedure
APN for StraightTalk added to standard AT&T APNs (May need to add your own APN for your data to work. Google is your friend)
'Big Data' standard (/data is as big as your sd-ext partition on your sdcard, if you choose to partition it. If not, will still work)
ext4 and swap file system supported in ROM and kernel (kernel already in ROM)
PERMANENT AreaRom made CWM 5 Recovery automatically installed for you
De-odexed ROM (programs load faster)
Root Browser Lite already installed
Quick Boot already installed
ICS Camera installed
Many other features!
Works with or without partitioning your sdcard. (If you DO partition, though, your /data partition will be as large as the sd-ext you create)
Note: CWM limits restore to 2GB..But, 2GB is PLENTY of room
NOTE: If you use a sd-ext partition, DO NOT USE LINK2SD OR ANY APP TO MOVE PROGRAMS! It already moves them...
IF your sdcard fails, or you remove the sdcard, you will lose all programs and everything stored in /data
=========================================
STEP BY STEP INSTALL INSTRUCTIONS:
Download both files below. Preferred way is via computer, then copy files to the sdcard (NOT in a folder)
Rename AreaRom-cwm-update.zip to just "update.zip".
Boot your phone into Recovery.
Select "Flash update.zip" or, if some Merits, select "Factory restore" option (or something close to it), and press the BACK button
When the temporary CWM comes up, select "wipe data/factory reset", press HOME
Select "install zip from sdcard", and press HOME
Select "choose zip from sdcard", press HOME
Select "AreaRom-Z990-2.2.0.zip", press HOME
When done flashing, select "Advanced", then "Reboot Recovery", press HOME
When CWM reboots, you can either "Reboot system now", or, you can partition the sdcard.
To partition, select "advanced" (NOTE: Partitioning erases all data on SDCARD...Make backups)
Select "Partition Sdcard"
Select any size you want for sd-ext (Recommend 2048 or less, or CWM has issues restoring backups to the sd-ext)
Any size for swap (If adding swap partition, you need an app like Swapper2 from the Play Store to use)
When done partitioning, select "Reboot system now"
FIRST BOOT MAY TAKE AWHILE! 5-10 minutes, possibly!

Good morning. Let me see if I can help you. Did you follow the directions in the OP of that thread you linked to? If you did then you should have downloaded two zip files. Without Google Play I am guessing you didn't flash the second file, which is the Google Apps. In other words, if you flashed the ROM then your phone did see your downloads on the SD card, so I am not sure why you didn't flash the google apps (gapps) package in the same session?
Anyway, here's my advice, assuming you downloaded the two zip files:
power off the phone and boot back into recovery.
Then follow the instructions from the OP:
Download the latest CyanogenMod 10.1 build (link below) (done, yes?)
Download the latest Google Apps Package (link below) (done, yes?)
Put both .zip-files into the root-directory directory of your SD Card: /storage/sdcard/0/ (done, yes?)
Boot into your Custom Recovery
"wipe data/factory reset"
"wipe cache partition"
"advanced" > "wipe battery stats"&"wipe dalvik cache"
"mounts and storage" > format everything except sdcard
Flash the two files with the Recovery via "install zip from sdcard" > "choose zip from sdcard"
"wipe cache partition"
"advanced" > "wipe dalvik cache"
"reboot system"
When I have the time, I try to go through Q&A threads and answer the ones with zero replies... Good luck, bud... once you get this straightened out you'll enjoy it.

Comment your Queries .
I have flashed a new rom on my phone with twrp 3.4.0.0
When I got to the new UI I had no free space (both internal and sdcard)
Back to twrp I took these steps:
1. Boot into TWRP recovery.
2. Select Wipe » Advanced Wipe.
3. Tick/check the Data partition.
4. Select Repair or Change File System button.
5. And lastly select Resize File System button.
that solved the internal storage size, but the storage of sdcard shows 80MB when it should read 128GB.
I tryed the same method for sdcard but it cant be done on sdcard selection.
Is there any solution without formating sdcard?
if not please provide a solution with formating on twrp.
I have searched for a solution but no result...
Please help! i have no time to search right now!
