What is the proper way to format a galaxy nexus? I want to clear everything possible and start fresh in an attempt to solve the abysmal write speeds I've been getting recently and I don't want to wind up bricking the thing in the process since I know certain partitions store the boot loader and more.
Other attempts to fix the write speed including fstrim, changing the mount command to enable trimming deleted files automatically, completely filling all free space with zeros then removing it, and none have helped yet. It gets approximately 0.10-0.15KB/s on random write with androbench, 2.0-5.5MB/s for sequencial write. I've never had anything less than 12GB free space, except when I tried filling all the free space
I want to format before reinstalling cyanogenmod and I understand there are risks involved that could brick my device so any instruction for what should and should not be touched would be greatly appreciated.
You need custom recovery installed (twrp or cwm). I have twrp. You need from recovery, for example twrp, wipe cache, dalvik cache, data and system from advanced wipe menu. After that, you should put in queue rom (which you are installing in zip format), then gapps(not all rom's need gapps, read install description for current rom) and custom kernel (not necessarily). After you just swipe on menu to proceed with installation and thats it

Make sure yu don't wipe "sdcard data" (there's a difference in System Data and SDCard Data). Marco207 mentioned that yu will have to wipe System Data. Rest yu may wipe anything, in fact, everything in case yu want a whole fresh ROM.
Hello everyone, it's very much time that I want to know the speech about decrypting my Nexus 5X. Now I'm stay with PureNexus and ElementalX, but if I go on Security > Cryptography, my phone is encrypted even if when I flash TWRP 3.0.0 , appeared decrypted.
Now I don't know if my device is decrypted or not. There is a detailed guide that I can follow so that I can permanently unlock my device?
Thanks to all
If you see in settings - security that your device is encrypted, it is... If you want to decrypt it you have to format /data and your internal storage.
1. Backup all your data
2. Dowload FED Patcher here and copy the zip to your device
3. Reboot into recovery
4. Wipe system
5. Reflash your rom, gapps and the fed patcher.zip
6. Do a factory reset and (!) format /data.
Reboot your phone, et voila, you are unencrypted.
Be sure to reflash fed patcher every time you update your rom, otherwise it will be encrypted on first boot without fed patcher.

When you flash ROM , gapps and patcher , and then do a system reset and format / data , the system does not start or not? But then formatting / data is getting through TWRP ? Thank you
I know I saw this process in a recent thread but I've misplaced it. If anyone can point me to it, I would be grateful.
I want to clean flash CM 13 on my OP3.
From what I remember, I'm supposed to store the CM 13 zip file and gapps file in the SD Card folder. Is that truly correct? The OP3 doesn't have an SD Card though I did find a folder.
If I do a factory reset and wipe everything, won't that folder also get wiped? Then how would I install the ROM from the phone?
Sorry, I know this is a straightforward process for many of you, and dirty flashing is easy. But I think a clean flash is better and I'd rather not guess and end up with a bricked phone I have to fuss with.
Again, I know this exact process is in a thread somewhere but I can't find it.
the phone storage is /sdcard/
u can use something like ES File Explorer and create a folder called CM13 or whatever u want
u do have ur bootloader unlocked and twrp installed, correct?
yes u will just the get cm zip file and put it in a folder (ex. /sdcard/CM13/)
i put the gapps in the same folder
create a nandroid backup
wipe/advance wipe - wipe caches/data/system !!!!Do NOT WIPE - INTERNAL STORAGE OR OTG!!!
then flash cm zip and gapps
Hi, thank you. Yes, bootloader unlocked, twrp installed and I've done it in the past on a different phone but couldn't sort out clean flashing from dirty flashing. I've done it correctly in the past, and it's also gone very wrong for me. I think I mistakenly wiped internal storage once and that was a disaster.
Somewhere I've also read about a factory reset through trwp.
I don't need to do that, or wiping caches/data/system is the same thing?

If you wipe internal storage, you will lose the zips for your ROM and GAPPS. You can connect your device and have it recognized on your PC from within TWRP if you do accidentally wipe your internal storage.
Factory reset doesn't wipe the system partition as that would remove your OS. Most Roms will wipe your system partition before it installs itself so generally you don't have to wipe the system partition manually, but it's good practice.
Clean flash = wipe dalvik, cache, data; then install ROM (which will wipe system before it installs, or manually wipe system before the ROM install for good measure).
Dirty flash = flash ROM, then wipe dalvik and cache. The only time you should do this if the ROM you're looking to flash says it can be done (ie. CM nightlies).
hi,
I bought a new redmi note 8 phone, unlocked the bootloader, installed TWRP .
Everything worked fine, until now. Now I want to backup my current modified stock ROM, but TWRP failes.
I got the problem very fast: TWRP can read all files and folders on the microSD car, but not in the internal storage folder.
Everything can be read by TWRP, except the sdcard folder.
Here he only shows strange names
something like:

How to decrypt permanent without losing data?

to decrypt phone :
Make sure you have a backup of your data copied in PC.
- In TWRP go to Wipe and select Format Data(don't go to advanced). Type yes and format data. [This process will format all your internal so make sure your data is backed up].
- Go back to TWRP home and Reboot > Recovery (Don't reboot system).
- Flash this zip.
- Reboot > System.
unfortunately there's no way to decrypt without losing data. Also if you're on a decrypted device then you have to format data everytime you flash any rom or update your current miui rom..I suggest using orangefox recovery to prevent this in future. Follow this guide for orangefox recovery.
I was attempting to install the Begonia Recovery Project for Miui 12.5 (android 11) using the fastboot method. But when I reboot into this new recovery and look inisde the "install" tab, all my folders from my main storage are made up of random letters and numbers.
I assume that this means that my files are still encrypted but I am not sure how to decrypt them.
I am running MIUI 12.5.3 Global edition on android 11 and the Begonia Recovery Project version I downloaded and installed was from this website : https://www.pling.com/p/1556862/
Furthermore, I have a unlock pattern on my phone but when I boot into the custom recovery, it doesn't ask me for my unlock pattern. Could this be the reason all my files are named with random letters and numbers?
It won't let me boot back into my operating system and when I try, I get an warning saying "No OS Installed! Are you sure you wish to reboot?". Rebooting leads me right back into the custom recovery, with all files still named with random characters.
I would prefer to be able to boot back into my system without having to lose any of my personal files on my phone (if that is possible).
Any help is greatly appreciated and I thank you in advance

This is the reason why everyone recommends taking a backup of your files and resetting your device prior to such attempts. Unfortunately, most likely you will lose part, if not all of your files.
That No OS Installed error is normal since MIUI is a system on root OS and TWRP isn't able to detect them.
That random named folders is your internal storage but it's encrypted. You'll need to enter your passcode every time you boot to TWRP. If it doesn't ask you go to Mount and select Decrypt Data
To disable encryption you'll need to format data and install Disable ForceEncrypt. Doing this will erase EVERYTGHING. (except Find Device,IMEI's etc)
I would recommend you to install this TWRP to decrypt them.
If your device boots back to TWRP, it might be triggering Rescue Party. (click the 3rd button on the bottom of the screen to view the logs)

I had installed twrp like this before and never had this type of error. But yes, the smart thing would definately be to always have backups. Lesson learned for next time!

Thank you for the fast reply.
I installed the twrp that you recommended. TWRP still isn't asking for my passcode and I can't find a "Decrypt Data" option in the Mount section. The only checked options in Mount are "Data", "Cache", and "Micro SD Card".
Is Disable ForceEncrypt needed in order to be able to boot back into my operating system? Is there any way to boot back into my OS without this?
Thanks again for the fast reply!

That zip can only be used if your data is formatted. If you flash it without formatting data you'll be making the situation even worse because it won't allow you to decrypt anymore. (it makes the phone think data isnt encrypted tho it clearly is encrypted)
Also did you check the logs as i suggested to determine the reason why the phone is not booting?

Whoops, I used the twrp you recommended without formatting the data. Does this mean my data is forever undecryptable?
I checked the logs and indeed it is triggering the Android Rescue Party.
It suggests possible solutions that are
wipe caches, and/or
Format data, and/or
Clean-flash your ROM.
The reported problem is :
'--reason=enablefilecrypto_failed'

No i didnt meant that, i said the Disable ForceEncrypt zip needs data to be formatted.
The reported problem unfortunately means your phone cannot setup encryption. (thats why twrp won't decrypt it)
The only solution is to format data to make the phone usable again.
(you might as well flash the disable encryption zip after formatting the data since encryption on android is a pain in the ass and it makes the phone a bit faster)
By the way, do not wipe data, just click Format Data and format it since it doesn't get rid of the encryption properly.

Thank you so much for your informative responses.
Apologies, I thought you meant that flashing different twrp would lead to undecryptable files.
By formatting data do you mean the parition on my phone called "data"?. I forgot to add that files in my "data" folder have sensible names and don't look encrypted. Is it normal for it to just encrypt my internal storage?
By the sounds of it, I think I will proceed with your suggestion of formatting the data. Just to clarify, will this method also remove everything in my internal storage, eg pictures, music, videos?. Is there a way to continue with this method without having to lose those?
I appreciate your help greatly.

They actually encrypted the whole partition till Android 10. This required you to enter a password before the phone boots up but now they only encrypt the internal storage,apps and app data so you don't have to enter a password anymore before the phone boots-up.
Yes formatting the data will erase everything on your device including the internal storage.
Because they are encrypted just like the other part of data there's no way to save them.

I see. So could this have been avoided if I had flashed the twrp after disabling my password? Is it a smart practice to disable your password before doing stuff like flashing a custom recovery?
Obviously losing all my data and internal storage is definately a kick in the nuts. But it is also my fault for not backing up my data before experimenting like this.
Could you please send me an oultine of the steps I need to follow in order to proceed with your method of getting my phone working again. Frankly, I have little experience in this area and I'm afraid i'll make a mistake in the process. I also trust in your expertise and experience far greater than mine.
Thank you again!

Simple, enter TWRP, go to Wipe, click Format Data, type yes then hit enter. Your data will be wiped. reboot the phone in Recovery mode (not to the normal OS or else the phone will encrypt again) again so the internal storage gets created.
Plug your phone into a PC, download this:https://zackptg5.com/downloads/archive/Disable_Dm-Verity_ForceEncrypt_11.02.2020.zip
copy it to your phone and install it. If you want to use Magisk, install Magisk first then this zip file. The encryption will be completely disabled.
To answer your first question, It wasn't your fault because i have no idea why your storage got corrupted in the first place but you should definitely disable the password (or disable the encryption if you want to use a password) before doing anything.

Since I am reseting my phone to its factory settings, I researched into some ROMs that I may use instead of MIUI. I came across the Pixel Experience ROM and I'm considering installing it.
I read somewhere that flashing a ROM involves having to disable encryption every time you flash a new ROM or something along those lines. Will installing the Disable ForceEncrypt disable encryption permanently or will I have to considering installing it again if I want to flash the Pixel Experience ROM?

You will have to install it again if you install a new ROM or kernel since it modifies both of them (they both get wiped if you install or update the ROM.
I recommend you follow their install guide since a lot of people get confused when they see errors.
Flashing PE A12
1. Flash latest Firmware. 2. Flash latest Dynamic TWRP. 3. Reboot to Dynamic TWRP. 4. Flash latest PE rom zip and then format data. 5. Reboot and enjoy. Links Here: Dynamic TWRP: TWRP For A12 Note: If you see any red line errors on twrp just ignore them and continue flashing. Also before...

Thank you for all your help. It was probably simple and easy for you but for me, I had no idea what I was doing and would never have done the steps that you suggested so thank you. I really appreciate all the help you've given me.
I just have one last request that is : do you know any good backup services for android? I know about services like google photos for backing up photos and videos, but I was wondering if there were any that backed up the android as a whole, including app data/progress, photos, videos, notes etc.
Thank you again for all your support and making this process very simple and easy and wish you all the best.

Google One app can backup photos,SMS, phone call history and redownloads all of the apps (except apps that were installed from an apk file)
Pixel Experience actually bypasses the Google Photos storage limit so you can backup your entire gallery without problems.
For notes just use Google Keep, it syncs the notes to your Google account.
App data can be backed up by Titanium Backup or Migrate. (i suggest you test them before backing up your entire app data as suggested by Migrate developer)
I don't exactly recommend backing up Data as a whole since your only option is TWRP and TWRP loves to complain when it comes to backing up and restoring.
Thanks for the best wishes and i wish you all the best too. Have a good one.
