[RECOVERY][TWRP][ROOT] Ulefone Power - General Topics

I've created TWRP 3.0.2 from sources (to be honest - only TWRP, Kernel is prebuilt from Stock ROM)
HowTo Flash TWRP

Or extract twrp.img from zip File and use Apps like Flashify (root required)

 @BlueFlame4

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.
Greetings

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

getting stock rooted Calkulin rom converted to data/cache f2fs

@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
Code:

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?

Encryption failure

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.

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

Hello again,
Is there any working recovery for this tablet.
Its very very difficult to find a custom ROM.
Are people using LineageOS ?

Advice needed porting TWRP to AllWinner a50

Heya guys!
So I've been busy making a TWRP recovery image for my unlocked chinese tablet (a Deejoy q728) that I bought from Amazon. It's a reaaaaally generic one with literally no firmware available over the entirety of the webs(yes I followed every tutorial you could think of that explains how to find firmware, believe me *sigh*).
Now I've gotten TWRP 2.3.6 to actually boot. I used the recovery img from another tablet with almost the same hardware(Concord HS or something) as a base and brought the necessary files into a TWRP 2.6.3 for the AllWinner A23 SoC. with Android Image Kitchen. The steps I took are from this post on DroidWin. It boots but I am encountering the following(major) problems.
1. Even though it displays in landscape, the touch screen seems to think it's in portrait.
2. Partitions just can't be found whatsoever. I think this might have to do with the fact that I don't know too much about fstab.
3. Adbd doesn't work.
By the by, I also edited the fstab files so that they contain the specific partition info of my tablet, not the Concord, as the Concord has several partitions that simply don't exist on mine. Code for twrp.fstab and recovery.fstab down below:

Edit: The main reason I really want this to end up working is because there are a ton of cheap allwinner a50 tablets and most of them(at least mine) are bootloader unlockable. Add Magisk to these babies and voila! Ya got a cheap device that you can theme to your hearts content. Toying around with tech has always been my thing haha.
So if anyone has any tips for me to get a sorta head start on this, I would really appreciate it!

Heya guys!
So I've been busy making a TWRP recovery image for my unlocked chinese tablet (a Deejoy q728) that I bought from Amazon. It's a reaaaaally generic one with literally no firmware available over the entirety of the webs(yes I followed every tutorial you could think of that explains how to find firmware, believe me *sigh*).
Now I've gotten TWRP 2.3.6 to actually boot. I used the recovery img from another tablet with almost the same hardware(Concord HS or something) as a base and brought the necessary files into a TWRP 2.6.3 for the AllWinner A23 SoC. with Android Image Kitchen. The steps I took are from this post on DroidWin. It boots but I am encountering the following(major) problems.
1. Even though it displays in landscape, the touch screen seems to think it's in portrait.
2. Partitions just can't be found whatsoever. I think this might have to do with the fact that I don't know too much about fstab.
3. Adbd doesn't work.
By the by, I also edited the fstab files so that they contain the specific partition info of my tablet, not the Concord, as the Concord has several partitions that simply don't exist on mine. Code for twrp.fstab and recovery.fstab down below:
Code:
twrp.fstab:
/boot emmc /dev/block/by-name/boot
/recovery emmc /dev/block/by-name/recovery
/system ext4 /dev/block/by-name/system
/data ext4 /dev/block/by-name/UDISK flags=encryptable=/dev/block/by-name/metadata
/cache ext4 /dev/block/by-name/cache
/misc emmc /dev/block/by-name/misc
/external_sd vfat /dev/block/mmcblk1p1 flags=removable;storage;display="SDCARD"
/usb-otg auto /dev/block/sda1 flags=removable;storage;display="USB-OTG"
recovery.fstab:
# 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
#<src> <mnt_point> <type> <mnt_flags and options> <fs_mgr_flags>

I realize this port is now months old, but I did want to ask how your TWRP port worked out? I'm presently working on Allwinner-a50 and Allwinner-100 tablet projects.

Welllll I have no idea how I did it, but I got it to boot. Touch screen drivers functioned overall but while being horizontal, the touch screen responded as if in portrait, so I literally ended up measuring where what button would be on the touch screen compared what was actually displayed. I eventually gave up as something tells me that the A50 might have very proprietary storage drivers, because no matter what I do, twrp refuses to see any device attached. Also, though most allwinner socs are well docd, the a50 isn't as much and afaik the allwinner barely acknowledges the a50. Though I am really happy I got to develop some more experience with things like fstab and it was a lot of fun

Outstanding job. That's no small feat when dealing with Allwinner, and especially their more obscure A-series chipset like the a50. So, TWRP will not recognize USB OTG device or other attached devices?

It won't even recognize the internal storage. When maneuver my why with the barely functional touchscreen to the log option, it just shows a long list of "couldn't mount"s. And no matter what I do TWRP has zero access to internal or external storage. Be it otg or microsd. I've tried several way of formatting the fstabs layout. Be it the average template I would find within twrp, or base my fstabs on those in stock recovery. Anyhow, it was taking alot of time in my life and started to get annoying /hj. Though I am glad I developed some experience. But I wanted to make something that would require alot more time, but would be alot more fun to make. It's a series called "Bull[censored] simulator." Though it's not really a simulator. And the real game lies within. Well... The game itself. As in the hexadecimal, the itchio page's assets and so on. Atm I am busy with a part that inserts it's lore into a Pokémon rom hack I will probably call Bull**** Sim: Pokémon Edition(Working title of course lol) so sorry for abandoning this job. Though I AM glad that people still take interest. Maybe I'll get back to it someday if I ain't beaten to the chase
