Hi all
I have two Nexus Grouper 2012 running SLimLP, cache and data are wiped to F2FS, both are runnning fantastic
I've used TWRP on device 1, backed up everything as a 'template image' to restore to device 2. Switched device 2 on, brilliant, all works great.
However, when I wipe the dalvik and cache on device 2, the dalvik wipes, but twrp displays straight after wiping the cache, 'cannot mount partition'. On device 1 this doesn't happen.
I reboot device 2, and it's fine, is it a false positive and just ignore it?

Hello All!
I've owned every Samsung Galaxy and both Nexus 7's and have successfully done all the basics (rooting, CWM, custom ROM) using Odin, ADB, and Fastboot. I've reached a problem that has stymied me, and Googling has thus far revealed no solutions.
Hopefully this question isn't as stupid as it seems to me.
Background
My AT&T Galaxy S4 has been rooted, has CWM recovery installed, and is running SlimBean's version of Android 4.3.
The phone was encrypted using the ROM's encryption (Settings >> Security >> Encrypt Phone). There is no decrypt option.
I installed the latest version of the ROM without realising that CWM's "Wipe Data/Factory Reset" option yielded errors due to the phone's encryption. Very stupid of me. Now, the phone works if I can get it to boot, but getting it to boot is a huge hassle that involves wiping /cache and re-installing the ROM every time.
Problem
I need to wipe data/factory reset and re-install the ROM in order to prevent the reboot problem from constantly occurring. I cannot do this from CWM due to the encryption of the phone.
Things I have tried:
1) Using ADB to mount and format system, data, cache
2) Using recovery to mount and format system, data, cache
For both, mounting and formatting system and cache were successful. Mounting and formatting data was unsuccessful.
3) Rebooting into Fasboot and using fastboot -w
For this, my Windows PC and my friend's Mac didn't recognise the device.
4) Using AirDroid to wipe data remotely
Using avast! to wipe data remotely
Using Android Device Manager to wipe data remotely
Asking my Exchange Admin at work to wipe the data remotely (maybe?)
None of these worked. The phone just rebooted like normal.
Basically
1. How can I wipe data/factory reset my encrypted phone?
2. How can I format the /data on my encrypted phone? Is this the only way to achieve (1)?
3. If I borrow a friend's Mac, and install Android SDK, would fastboot -w work on an encrypted phone?
Thanks bunches,

Format the phone completely via TWRP, and flash AMDL via ODIN. That should resolve your issue.
Hi all,
Since I tried to update my phone, I'm stuck at boot after updating apps.
Screen displays 'Launching apps' but the phone seams stuck.
I already triedd to wipe cache and dalvik cache.
I also wipe several partitions (including cache, dalvik cache, system, data) and then try again to install and boot the ROM but same result.
Finally I wiped all the partitions (cache, dalvik cache, system, data, internal data) and install ROM again but I'm still facing the problem
Then I found this thread : http://forum.xda-developers.com/galaxy-nexus/help/stuck-android-upgrading-starting-apps-t2825113
So I tried to use 'Fix permissions' option without any success.
After that, I also connected to the device with adb and execute fix_permissions.sh script provided in the thread by it doesn't work better.
Do you have any idea how to fix that?
Thanks by advance.
Have you tried sideloading another ROM and flashing to see if the issue still persists? I assume you get this after it optimizes all the Apps?
I forgot that I have no more access neither to adb nor fastboot...
I read that my last chance is LGNPST.
Do you have any recent pointers to a process to recover my phone, please?
Thanks
I was on AIOSP rom and this was my first custom. I wanted to revert to stock so I rebooted in TWRP and wiped all partitions (dalvik, cache, data,system), after that my phone is not getting detected in recovery, and my fastboot also showing these stats, all empty.
Product_Name - QC_Reference_Phone
Variant - MSM UFS
Bootloader Version - (blank)
Baseband Version - (blank)
Serial Number - XXXXX
Secure Boot - Yes
I forgot to take a backup and did this. Now, I tried flashing OOS 4.5.14 using TWRP and it went all good, but the entries are still empty in fastboot mode. Please help, just got my OP5 2 days ago.
I think you wiped more than just system, data, dalvik and cache.
Yeah man, i wiped data, system, dalvik and cache. What can be done now? It is working fine, but the issue is in fastboot everything is empty
the fastest way

Hi, I'm from Nougat 4.5.14 and these are the steps I made:
1. Flash codeworx then reboot to twrp
2. Wipe cache and dalvik
3. Install OS 5.0.2
4. Install magisk
5. Wipe cache dalvik
6. Reboot to system
However after rebooting to system it started bootlooping so I decided to reflash OS and wipe data as recommended. So I power off the phone then hold volume down + power to boot to recovery. However when I boot to recovery, file folders started to become random names like its encrypted. Luckily I backed up my internal storage and data so I'm okay to flash everything but can someone help me how to fix the twrp random file names and the steps for reflashing the OS?
EDIT: I rebooted to recovery, wiped dalvik, cache, and data. flashed OS 5.0.2, wipe dalvik cache, flashed magisk, wipe dalvik, reboot to system and it does not proceed to circling dots. So what I did is just, wipe dalvik, cache, data, flashed OS, wipe again dalvik cache, boot to system and it proceeds to circling dots however it takes so long that I can consider this as bootloop. I'm very tempted to wipe everything (data, system, internal storage, cache, dalvik) then just flash again the OS but I don't know if it would work so I hope someone could give me some steps how to fix this
Edit 2: This is solved now: What I did is just after trying the flash OS with no magisk, I booted to system. However, i just dont boot at all so I decided to boot to recovery again, but this time the recovery is the stock one. I wipe everything I could including cache, system reset, and data (music pics etc) and it booted to the system in no time but everythings lost.
You have to format data... Not just wipe it. From TWRP go to format data, write yes, and let it format everything. Then transfer over to the phone all the fil a you need (ROM, kernel, no verity zip) and flash them as per the instructions of your rom thread. You should be fine.

You can still show other solutions as others may need it sometime
I see dalvik / art cache and system, data
which one do I chose to clear system cache, without bricking my system?
You have only one option - dalvik.
Cache is old days from, it doesn't exist anymore on pies. If you try to wipe you'll get an error in TWRP.
System and data are speaking for themselves. Wipe system - brick phone, wipe data - loss of apps and personal stuff
