Do this at your own risk i will not be responsible for any damage. i am not a C7 user and i havent tried this...
Do a Backup or have a stock rom downloaded from sammobile site.
Your device must have atleat 60% of charge.
Goto Settings -> Security and enable the "Unknown sources".
For your safety, please take backup of your importent stuffs.
Turn on USB debugging mode from Developer Options on your Samsung Galaxy C7. To turn on USB debugging you have to enable Developer options, GoTo settings -> About and tap multiple times on build number.
turn on OEM unlock from developer options..
and here i repeat "on your own risk"..

For some reason no need to oem unlock (bootloader not locked properly??) so have twrp without needing to wipe data, but now remains the encryption problem as this trwp doesn't support it, I have compiled twrp for mtk in the past with encryption support but doubt I can recall what needed to be done
TWRP not working
When I install the TWRP recovery and start the phone with this mode to install the two files
1) no-verity-opt-encrypt-5.1
2) SuperSU-v2.82-201705271822
the phone does not see them and it is impossible to proceed further.
Furthermore, the operating system does not even start, so the original firmware must be replaced with the flash tool.
Has anyone found a solution to this inconvenience?
Thank you

1. Userdata is encrypted, and the TWRP here isn't compiled to be able to decrypt it. So you'll need an sdcard with those zips on it
2. The os won't start if it deems its been altered - that's partly what zip 1 is for.

No custom ROMs - I think there is a clone device [Panasonic Eluga C] so we have another stock ROM from them.
I haven't attempted porting anything yet, let alone building anything from source [a source built twrp should be trivial] - i've lost yet another hard-drive recently so light on diskspace & sdcards so not able to do much atm.
For completeness: stock ROM > http://ulefone.com/download/mix.html [newer than the one on needrom]
OTA > http://hwfotadown.mayitek.com/ota/r...NE_N_V0.6.9.1_S1712221514261911507/update.zip

twrp and now?
Hello,
i have an old ulefone mix mt6750t with the screen damaged but still 90% working, i thought i would use it on android auto but i needed rooting.
So I informed myself a bit, go unlocked developer mode and usb, downloaded adb and twrp and magisk etc ...
I unlocked the bootloader from the settings then used adb and installed twrp which starts but asks me for the pass to decrypt, then I swipe and delete the encrypted data.
Then with adb sideload I install magisk 20 and check opt encript, but the phone always goes to twrp, it does not restart ... mmm and the orange mode message comes out but it should be normal ... someone knows how to go on to restart it normally and not with twrp?
Thank you

After flashing I can only boot to normal mode and stock rom will replace twrp with stock recovery.

I don't have the device but adb reboot recovery should work right? Or Power Don + Power should lead to recovery in most mobile phones.
You can even use "fastboot boot recovery.img" where recovery.img is your TWRP recovery. you can use it to boot into TWRP and decrypt device if needed and then flash it permanently!
hey did you tried to flash or boot magisk patched boot img ???

I unlocked bootloader of realme c2 by following the steps which I described on page 1.
Are you following the procedure exactly?
I think you have driver issue.
check USB devices in Device Manager when Phone is connected in fastboot mode.
Check by connecting USB cable in USB 2.0 port.

now with this information we should be able to patch boot.img using magisk and flash it to our devices to root it.
to flash your device do the following: reboot into fastboot mode (power + volume up and select fastboot) then in a terminal type:
to unlock the bootloader:
fastboot flashing unlock
to flash an image to your device:
fastboot flash <partition> <image>
the stock images and the scatter file will follow

That's good to hear.
Although if it can be rooted it might be sufficient for me to kill all not needed apps via adb and use Magisk for AFWall+.
Actually I've read about the possibility of a GS version with a better camera so I might wait a while before getting one.
well there arent any unneeded apps

First of all: Thank you very much! Everything has worked so far and the device is rooted.
But I still have one question. How does the device behave when the official updates from Gigaset are installed via OTA? The GS4 reports it would have security updates. Can I install them without losing root privileges? Does anyone already have experience? Thanks in advance!

I have now simply installed the June 2021 update. The good news: It worked. The slightly less good news is that you have to flash the images again. But flashing also works with the latest version and the update check tells that there are no new updates. So it seems to work.

Here is, what I did: (on your own risk)
As far as i can remember, i did not have any issues.
Step 1: Unlock your device
1. Enable Developer Options: Tap 10x on Build-Number (Setttings -> About the phone -> Build-Number)
2. Enable Bootloader Unlocking -> activate OEM-Unlock option (Settings -> System -> (More) -> Developer-Options)
3. Enable ADB Access -> Enable USB-Debugging / ADB (Settings -> System -> (More) -> Developer-Options)
4. (Set USB-Settings (Message-Center) from "No tx" to "PTP")
5. Connect phone to usb port, grant permissions on phone and check connection with `adb devices`
6. Boot to bootloader: `adb reboot bootloader`
7. Unlock Bootloader: `fastboot flashing unlock`
Step 2: Download GSI
1. Reboot your phone and install Treble Info App
(https://play.google.com/store/apps/details?id=tk.hack5.treblecheck&hl=en&gl=US)
GS4 should support AB-Partitions
2. Download GSI: https://sourceforge.net/projects/andyyan-gsi/files/
For GS4: treble_arm64_bv*
Step 3: Install GSI
1. Boot to recovery: `adb reboot recovery` or Volume Down + Power
2. Wipe data
3. Wipe cache
4. Enter fastboot
5. Flash GSI: `fastboot flash system <extracted-gsi-image>`
6. Reboot and enjoy
*. (just in case it does not boot, reboot to recovery -> enter fastboot and flash vbmeta: `fastboot --disable-verity --disable-verification flash vbmeta vbmeta.img`)
This vbmeta-image should work (see post #6): https://forum.xda-developers.com/attachments/vbmeta_disabled-img.5325563/
HI Develoopers, please can anyone help me to solve my Tecno spark 4.
it doesn't boot and i tried to re-install new rom but i can't access the usb debugging since the phone won't boot.
how can i enable usb debugging in factory reset/recovery mode?
If a TWRP for this phone exists then you can try to boot into this TWRP - what is done by means of Fastboot - and from within TWRP you can enable USB-debugging because TWRP has an ADB interface and support.
