Ok so, i tried to flash only the recovery image and the device went on bootloop, so i cant flash the twrp, but then i found this: https:// forum . fairphone . com /t /howto-use-twrp-without-flashing-it-e-g-for-backup/23747/2 (without spaces). And so, now i wanted to ask: can i root with this method?
I've never been able to get the fastboot boot command to work and I'm unsure what you're even trying to do, but if you flash TWRP, do whatever you need to do, power the phone off then flash the stock recovery again it shouldn't be permanent.
Also if you're bootlooping you might need to flash the boot.img too.
Furthermore, did you make sure to download the LP ROM if you're on LP or the MM ROM if on MM?
If you have an unlocked bootloader you can flash the custom recovery, boot straight into it, choose to not modify the system partition, flash superSU or whatever else you need (xposed? IDK), then from the reboot section of the recovery reboot to the bootloader, and flash the stock recovery. Then you should be able to boot into a rooted phone without custom recovery (I'm still unsure why you'd need/want this, but I've done it once in this exact way).
If i can have the custom recovery without bootlooping i would leave it, but still thx

Ok, i just tried to do that procedure (flashed recovery, installed superSU) and now its still bootlooping! maybe superSU ver2.46 is not ok for MM v34?
Ok so, I found online a LineageOS 15 ROM for Wiko FEVER 4G but, before I install it, I want to ask if someone here can test it if there are any bugs or works fine. I would post here the link but I can't, sorry, but you can just google "Wiko Fever lineageos 15" and it would be the first result showing. Thanks
