Dears,
I installed TWRP on SM-A530F/DS and flashed no-verity-opt-encrypt-6.0 and formatted data to let the phone boot.
Well, I'd like to re-encrypt the phone like I've always been doing on sammys after TWRP or Magisk installation, but it doesn't work on this phone.
No matter if it's Nougat or Oreo, applying encryption nothing happens and phone crashes backing to lock screen in a minute.
Any suggestions?
Thanks everybody.
Id like to encrpt mine too. Twrp and rooted with magisk. when i try and encrpt it just reboots after a minute. SMA530W
Dear @jcadduono,
sorry to bother, I think this issue is caused by Samsung's firmwares but, in your opinion, could it be related to no-dm-verity patch?
Or, is it possible to edit the patch in order to not to disable encryption?
There's a modification (red color in code), I think operated by the patch, to ramdisk's fstab.
Stock fstab:

Patch operation sounds correct, but this is the only device that fails in encryption them.
Thank you so much.
It's actually not uncommon for a ROM to not be able to re-enable /data encryption from the regular settings, once disabled manually.
As far as I can tell, no-verity-opt-encrypt-6.0.zip replaces the "must encrypt" flag on /data with a "can encrypt if you want" flag. When you format /data from TWRP after flashing that zip, you obtain a non-encrypted partition, but it should be possible to re-encrypt it.
Have you guys tried encrypting data from the adb shell? Details here: http://niki.hammler.net/wiki/Android_Device_Encryption#Setting_up_encryption
This is also recommended reading: https://source.android.com/security/encryption/full-disk
You should also check the system log to see what goes wrong when you try to activate encryption. This is how: https://android.stackexchange.com/questions/26123/android-boot-up-messages-for-debugging

@Calkulin (because you uploaded the rom)
@katinatez (because you are good folk)
@zaphodbeeb (becasue you are the one that taught me to convert to mixed partitions)
hoping to get some help on this for me and others wanting to try out the update.
i am trying to get the rooted 05q to work on my mixed f2fs/etx4 partitions. data/cache f2fs - system etx4 so i don't have to wipe my /data partition.
i have gone through several routes so far to no avail. sideloading/flashing. flashing the ak 113 kernel with instructions for the new update. updated to the new katinatez philz with the new f2fs comits.
1. updater script - i did not see a need in changing the /data to use busybox for f2fs as the line of code is already there.
2. fstab.bacon - i used zaphods new f2fs all or f2fs mixed

at first i just flashed the the new extras file (firmware modem linked with Calkulin's rom. then flashed the rom. i got stuck on the bootanimation for ten minutes.
then i thought it might be the kernel not 'jiving' with f2fs. so i sideloaded the ak_113 (on top of what i had already done) with the instructionsfrom @xlollomanx (thanks) linked from the ak kernel thread.
still.... stuck on cyanogen boot for ten minutes
then i restored my backup and sideloaded everything, ak kernel and all, from scratch.
once again... grrr. still stuck on boot animation for ten minutes.
any ideas on what i can do?
How to convert NAND ROM to SD-EXT ROM for MultiBootloader
Code:
After following this guide, your ROM can be use with [URL="http://forum.xda-developers.com/nokia-x2/development/sbl-multibootloader-v1-00-04-10-2015-t3217360"]MultiBootloader[/URL]
THIS GUIDE IS NOT FOR NOOBs
Requirements
Knowledge about Android Image Kitchen
Notepad ++
A nand ROM extracted
Instructions
Delete the RED COLOR
Add the BLUE COLOR
Step 1: Modifying boot.img (FOR STOCK KERNEL ONLY) - Check post #2 to download the modified boot image, you don't need to edit it yourself.
Use Android Image Kitchen's unpackimg command to unpack the boot.img file from the ROM your want to port.
Go to Android Image Kitchen\ramdisk folder, edit these files:
fstab.qcom
Change like this:
Code:
# Android fstab file.
# The filesystem that contains the filesystem checker binary (typically /system) cannot
# specify MF_CHECK, and must come before any filesystems that do specify MF_CHECK
#TODO: Add 'check' as fs_mgr_flags with data partition.

Find and change all /system/ to /system-EXT/
Find and change all /custom/ to /custom-EXT/
Save.
Step 3: Create the ZIP
Make sure you have copy the modified boot.img to the ROM folder
Select all the files and folders in the ROM folder (custom, system, META-INF, boot.img,etc..)
Compress into ZIP file.
Done.
<EDITTING>
I have modifed the boot.img to boot into sdext ROM:
For stock based ROM: stock_ext.img - thanks to @symbuzzer for adding some features and fixing the ril & sdcard bugs
modified_stock_insecure-kernel.img - (Maybe I've made some mistake in this file. I don't recommend to use this, it can cause some bugs with sdcard0. Better modify it yourself.)
For CM11 based ROM: ext_cm11.img
Great ! Im waiting for this
Bro how can intsall the rom
I m try but couldn't with me
Plz help ??
@SonnySimon this method doesnt work on Stock Kernel/Rom. I will attach stock kernel on XDA today. You can compare mine with yours and update this post. Thanks

[HOW TO] BOOT FROM SD CARD [SUCCESSFULLY] on QMobile Z8 with BRICKED/DEAD eMMC

How to convert NAND ROM to SD-EXT ROM for MultiBootloader
Click to expand...
Click to collapse
I have been successfully able to boot from SD card on QMobile Z8 by partitioning SD card on a Ubuntu machine using 'parted' and 'fdisk' commands, replicating eMMC partition table and then flashing factory firmware images to these newly created partitions using 'dd' command. Then I modified "fstab.qcom" & "init.tegra.rc" files in kernel (boot.img) and "recovery.fstab" and "uneventd.rc" files in twrp recovery to initiate mounting and booting from sd card instead of internal memory. It was successful after some experiments. Details can be found here:
https://forum.xda-developers.com/android/help/how-to-boot-sd-card-qmobile-z8-bricked-t3712171
But I have still a few queries to be answered. Please have a look. Any help, comments, information or suggestions will be appreciated.
Hi developers, I'm trying to compile cwm from sources. When I do "make -j4 recoveryimage" I can test the recovery and it works, but when I flash it seems it installs in download mode (see attached image). I think the recovery.fstab is the problem), but I can't find the problem
Here's my recovery.fstab:
Code:
# mount point fstype device [device2] fstype2
/boot emmc /dev/block/bootdevice/by-name/boot
/system ext4 /dev/block/bootdevice/by-name/system
/cache ext4 /dev/block/bootdevice/by-name/cache
/data ext4 /dev/block/bootdevice/by-name/userdata length=-16384
/sdcard vfat /dev/block/mmcblk1p1
I've created TWRP 3.0.2 from sources (to be honest - only TWRP, Kernel is prebuilt from Stock ROM)
HowTo Flash TWRP

Nice!
Perfect thanks!!!
Thanks for your work.
Are you able to create a twrp for the ulefone power 2, if I provide you a scatter file of the power 2 stockrom?
I already tried it myself but ended up in many bootloops.

Good evening.please help me.i want to uninstall custom recovery twrp (teamwin) can you tell me how to uninstall in order to install the official one?

After I unlocked the bootloader, I tried to port TWRP from Oukitel k6000 plus since both have same chipset MT6750T and same resolution. I tried to follow this guide on youtube video using Carliv Image Kitchen. But I failed. Heck, I tried to flash the k6000 plus recovery and nothing. Not even boot loops , the stock recovery still shows up.
Edit: I was partially successful. I was able to get to TWRP but touch screen not working. I connected a mouse and was able to change the Russian language of the original k6000+ TWRP port. But what is not working is the mounts of partitions. I tried to copy the mount points from fstab.mt6755 which is in stock recovery to the new port. But the new port doesn't have such file, instead it has goldfish fstab files, I tried editing them manually to match them, but it didn't work.
This is just a stab in the dark. If anyone know how to fix partition mounts and why touch screen not working, I would be grateful.
I replaced recovery.fstab from stock to the ported one also replaced default.prop.
fstab.mt6755 <- That comes with stock recovery

Ulefone Power2 volte is getting enabled.
I am not able to enable volte flag in ulefone power2... Does any one see volte flag as enabled. Even i am not able to root this phone
Please help
Joke title aside, I had an idea for getting unencrypted and thereby instantly mounting sdcard as internal storage.
The idea is simply going inti the fstab and simply changing the entry for /data into
Code:
/dev/block/mmcblk1p1
. This requires the sdcard to be freshly formatted I think (probably in either ext4 or f2fs)
Going even further, we could get back the internal storage and make it appear as an external sdcard, so it's not totally wasted. (In theory, maybe I'm overlooking something). For now, it's not in the modified fstab.
Only do this if you don't have anything to lose on the phone and on the sdcard
Here's the modified fstab. Would be interesting to see if someone could test it. Copy and paste the text in the spoiler into a new file called fstab.qcom (make sure to save in Linux line breaks if you're on Windows).
Make sure to make a backup of /system/vendor/etc/fstab.qcom before proceeding via adb pull or some other method.
Reboot to TWRP
Again, make sure you have backed up the file you're about to overwrite
Do adb push fstab.qcom /system/vendor/etc/
Reboot
See what happens

Looking forward to hearing from someone if it worked and how the performance is.
Good Luck with testing.

Emmc memory is much faster than sd-cards and even more importantly it's much more failproof than the regular consumer grade sd-card. But if low on storage for apps, sure

Wel it wasn't intended to be a serious mod. I'm mostly just curious if it works and need a guinea pig as I can't afford wiping my phone right now ?
