WHAT IS TWRP?
Team Win Recovery Project is a custom recovery for Android devices.
It allows you to back up and restore your data, flash custom ROMs to your device, repair broken file systems, and root your device.

Notice1:
U Pro has A/B partitions. to prevent issues its good to flash it in both slot, because i/we can not know on which partition you are

Notice 2:
This version only working on Eragon roms
Maybe soon I'll manage it to work on stock rom

Notice 3: Sdcard now working

DOWNLOAD
TWRP for 20180227 Base via Qfil Flashtools:
Go here : https://drive.google.com/file/d/1JZ59mO07Zc1a9kdA6j7LJvrgc9g2kf5d/view?usp=sharing

TWRP for 20180511 Base and newer:
Go here: https://drive.google.com/file/d/1RrWuncXsH8GtCTbaEgGpDffRUDK9fMVv/view?usp=sharing

INSTALLATION

if you use the old 20180227 Base you have to use Qfil Flashtools , because fastboot commands dont work in that Build.
we have a good guide of how to use FLashtools already
look here: https://forum.xda-developers.com/android/development/guide-elephone-pro-user-manual-t3775895


if you are on 20180511 Base and newer you can use fastboot commands
required : ADB and fastboot

enable usb debugging in developer settings.

do this:

Code:
adb shell
Code:
reboot bootloader
now we flash it in slot a
Code:
fastboot flash boot_a twrp.img
after that we flash it also in slot b
Code:
fastboot flash boot_b twrp.img
Special thanks to
teamwin for this awesome custom recovery
And @skeleton1911 for his help

I loaded up all my usual apps and settings and was going to do twrp backup and strange thing happened: the recovery doesn't see my external SD. I can see sd card's files from the phone but it's invisible in twrp. Funny, because someone couldn't flash ROM from sd yesterday and I did, I still have the ROM files there on SD. I tried to pick the sd storage for the backup and that's how I found out it's missing. The trwp was flashed per instruction: fastboot, 'a' & 'b' then I did a total wipe in twrp and flashed the ROM twice - that was it. Probably some conflict between a an b again? It can wait, am not in the hurry, this Rom otherwise looks really good, it boots faster then the stock, nice.

sorry for bringing bad news, I flashed that new ver. it shows SDcard(it wasn't there before) and that's it, it won't go 'up level', also in File Manager or Backup storage choices it shows externalSD with 0MB space.

Hey Guys, we have two parallel Upro Universes here, two seperate threads on "Unofficial twrp for Elephone u pro v3.2.1.0", would that be _a and _b? :)

reinstalled, reflashed, flashed and reinstalled and still no show for extSD in TWRP. But am all set for now, placed Eragon v.5 and Magisk Mgr on microSD/USB C OTG dongle and installed the ROM(zip) + Magisk(zip) from there via TWRP. Everything's good 'xept that 0 extSD. I was also able to do TWRP nandroid sys backup which went on that OTG dongle, some 3.8GB, that'll save me some time in the future I'd think :laugh: So, with the Springtime weather outside am gonna leave my computer stuff now and go out to ejnoy some of that Spring! See you later!
