Dear Xiaomi Redmi 4 Prime ¦ Pro user,
I'm not responsible if anything happens to your phone. If you execute this procedure properly then you shouldn't face any problems. I tried this procedure at one of my Redmi 4 Prime ¦ Pro running on Lineage OS. I have not tried this procedure with a phone running on original MIUI or any other rom but it is very likely that it will work with all roms. If anyone tries this procedure with any other rom please give us your feedback.
Before you proceed please backup all your important data and make sure that your phone battery is charged >80%! During decryption all your data will be lost!
1. Your bootloader must be unlocked and a custom recovery (twrp) installed
For more information on how to unlock the bootloader and install a custom recovery (twrp) please read here:
https://forum.xda-developers.com/android/development/guide-one-unlocking-bootloader-twrp-t3587493
2. Disable the encryption
a. Enter recovery mode:
+ by holding together "Volume Up + Power" until you see the MI logo, release "Power" button but keep pressing "Volume Up" until you see the recovery, or
+ by holding together "Volume Up + Volume Down + Power" until you see recovery
b. On the main screen of the twrp, click "Mount" and check all partitions
c. Go back to the main screen of the twrp and click "Wipe"
d. Then click "Format Data"
e. Type in "Yes" and enter
Reboot your phone. That’s it, you are done.
If my guide helped you pls click "thanks" and enjoy your phone. :fingers-crossed:

I believe unencrypted runs faster compare to encrypted phone, i tested it myself using encrypted phone there are noticable stutter when switching apps via recent app switcher key. Click this link for a video of encrypted vs unencrypted.
Thanks buddy, that would help me for flashing los beta rom.
Problem with disable encryption
When I check all partitions on mount and wipe --> format data, I loss all my data, so I can't flash any custom rom from my internal storage.

He said can't flash rom from internal storage, but do we keep flashing from other source like sdcard or OTG? Thanks!

Micro SD Card, yes for sure (I tried it myself). OTG I guess yes (i did not try it myself, but I don't see a reason why it shouldn't).
Internal storage, memory card and otg. All possible and I've tried. You can even full wipe even internal storage in twrp then copy the rom in internal and flash it in twrp.

I think you should make an emphasis to BACKUP DATA, because to remove encryption is simply rewrite your file (delete all then make a new non-encrypted one). So it's DEFINITELY DELETE ALL YOUR DATA.
Cheers :highfive:
After I wipe all data, should I flash rom again or reboot to system directly.?

Hi,
I just flashed myns warm 2.2 on my evo 4. Now I want to install hulu and a few other addons. The developer says to install them like you install roms, so should I just use ROM Manager? If so do I have to backup and wipe my phone first?
Thanks for the help,

pretty sure he meant you need to flash them from recovery and not use rom manager, as it doesnt actually install anything.

Ok thanks for clearing that up. Sorry for the newbie question, but how do you do that?
**edit
actually i just found i guide about how to do it on phandroid, my question is this:
Here is what the guides says:
RECOVERY
PUT ROM ON SDCARD
Before you begin, connect your device using the Mirco USB cable and place the Custom ROM you downloaded onto the Root of your SDCard. This means put the Zip file in the main folder itself. Not in any Sub-Folders of any sort.
STEP 1: TURN OFF DEVICE
Power down the device by holding the Power Button for 2 seconds. Allow it to shutdown completely. Wait about 10 seconds before next step.
STEP 2: BOOTLOADER
Hold down VOL DOWN + POWER until device boots into a White Screen.
Move to RECOVERY by using the VOL DOWN toggle and select by using POWER button.
STEP 3: BACKUP
Make sure to do a NAND backup of your bevice prior to Flashing a ROM. Refer to Section 3.
STEP 4: WIPE
Use the VOL DOWN toggle to move to Wipe and select by pressing the POWER button.
Toggle down to Wipe date factory reset and select by pressing the POWER button.
Once that has complete, toggle down to Wipe Dalvik-cache and select by pressing the POWER button.
Once that has complete, select Return.
STEP 5: FLASH ZIP
Use the VOL DOWN toggle to move to Flash zip from sd card.
Find the ZIP file Custom ROM you want to flash by using the VOL DOWN toggle. Select it using the POWER button.
Your ROM will now be installed onto your device.
STEP 6: BACK TO RECOVERY
After the installation has completed, you will be brought back main menu, use the POWER button to select the first option “reboot system now”. And your device will reboot itself like normal.
Enjoy your new ROM!

Hello.
I have recently attempted to update my P6800's firmware from stock Android 4.0.4 to a custom 4.4 version (one of Daniel_hk's firmwares.)
I have wiped data cache and user data, and the firmware, when I attempted to install it, gave me an "E: signature verification error" error. Attempts to reboot or to install a stock 4.0.4 or 3.2 firmwares from the microSD card failed with similar errors.
I was told I can flash the device via Odin, reducing it to 3.2 and then upping the versions properly, but I cannot switch the device on into download mode, because it is stuck in usual recovery mode.
Please help.

The options I get are
Reboot the device
Install stuff from SD card/navigate on SD card
Wipe data/factory reset
Wipe cache
Apply update from cache.
Which of them is the option you describe? Do I need to put the bootloader on the SD?

Greetings and welcome to assist. You are in stock recovery there so the option to reboot to bootloader is missing. You should be able to power down the tablet then boot into download mode with the power button and volume key
Good Luck

Do I need for it to fully lose charge? It just switches on to recovery if I let it run until the battery is dry, then charge it again. Powering it down treats the power button as enter button, so I cannot actually switch it off (unless I am doing something wrong.)
Thanks for the welcome, I appreciate your help.

There are only the power button and volume button on your device, no physical home button like a phone ? If press and hold volume down and power the phone should reboot showing the samsung logo. Let this happen twice then let go it should go into download mode
hi all
for solve all problems after update to nougat ..
just go to recovery by long press on (power and vol+ and vol-)
togather .. it will boot to revovery .
erease chache
then wipe data
(you have to make back up to your data)
then reboot
it will now start as new device
you will not find any problem .
(I TEST THIS WAY IN MY DEVICE)
it sccess ?
Yes, you just described factory reset. And to enter recovery indeed you need to press power and vol+ and vol- all simultaneously, but after you see the logo you should put your finger off the power button.

What do you mean? The phone won't reboot to recovery if you keep pressing the power button after the logo.
Way easier solution:
- After the update go to Google Play Store
- Check for updates
- Update all apps (this will include Chrome and maybe Google services)
- Reboot
Afterwards no issues at all.
Like the title says, I recently flashed CWM recovery with odin to my tab 2, after reboot, it stuck on the first thing it displays and nothing works.
Power button = device logo(?) loop
Power button + Vol. Up = nothing
Power button + Vol. Down = nothing
The tab run on stock firmware with root access. Got the file from https://forum.xda-developers.com/showthread.php?t=1722304

You can copy your data from your internal storage to the external sd without pc. Download the Aroma File Manager from here https://www.google.gr/url?sa=t&sour...ggaMAA&usg=AFQjCNEH8YsLeZ9hUCaOmQXRhJ2Yh2eYCA
boot in cwm and install it. Don't worry, it will not install anything, it will just open a file manager.

[UPDATE] I've flashed the ROM and it's up and running now. The issue now is most of the apps can't start/keep crashing.
Maybe because I didn't wipe the data. Thoughts?

You absolutely need to wipe the data and cache and dalvik cache. If you don't do that when flashing a rom you will probably have such or worse problems. (Before flashing you should also wipe system)

you should install twrp recovery and not cwm. cwm is not up to date. for the latest roms you need the latest common twrp
