[Miscellaneous Android Development] Laptapper:
Elephone U pro to treble resurrection remix laptapper mod android 8.1

Bluetooth and safetynet working!

All runs smoothly and everything what I´ve tested has worked.

If you find bugs, share them here and may be we can develop all together.

I´m not responsible for your phone, all what you do is on your own risk

Backup your data

if you´ve got booting problems after all then flash eragon10.3 via qfil

GAPPS included!

Best configuration menu ever, have a look to the attached picture

flashing guide:

Recommended is to make a full wipe of system, data, dalvik and via twrp factory wipe.

Flash via adb.

1. Copy img file in folder adb.

2. start bootloader

3. run in windows cmd with

fastboot flash boot V10_TWRP.img (if you didn´t have twrp)

fastboot flash system rrmodsystem.img

ignore messages, give time and you´ll see the progress, after finished wait some seconds and then follow next steps.

4. restart to recovery

5. flash magisk 17.1 zip via TWRP after flashing twrp and system

6. wipe dalvik and cache manually with TWRP file manager in folder dat\cache and dalvik

7. reboot system

8. If you want then you can flash extrasflashtwrp via twrp. Try and be happy ;)

9. enjoy

Safetynet:

To get magisk safetynet working you have to install magsk module MagiskHide Props Config and set in magisk configuration magisk hide, reboot and then

Run a terminal app and type:

1) su

2) props

3) Set the fingerprint with the following keys (pressing enter after each):

1 -> f -> 16 -> 8 -> y -> y

take xiaomi Mi A1 (it´s working for my u pro so it should be also ok for you.

MTP:

MTP works, but you have to go to developer settings usb and switch from mtp to ptp and back. May be sometimes you have to switch 2 or 3 times.

I´m new at development and so I didn´t know all......May be someone can help how to update the google security patches?

May someone knows how to update the RR files in the future easily.......

May be there is a permanent possibility for phone security fingerprint and not over magisk module.....

Let´s develop together!

Easy install

Prerequisits: bootloader unlocked, rooted, TWRP installed. Of course it is only for u pro!

This procedure should be work on every u pro:

1. start twrp and make a full backup to sd card

2. check your sd card, you must have a folder twrp with subfolder backups and ssubfolder with your phone modell like A208DD.....

3. download the rr_mod... zip and extract it to your modell sub folder (it should be only one path with the backup files)

4. start twrp and click wipe, factory reset, and again to wipe but advanced wipe check box dalvik, system,data, internal storage. After this click restore in the main twrp menu, choose sd card and you´ll see the rrmod backup. choose system, vendor and boot to restore.

5. After restore reboot recovery again and install magisk 17.1

6. at least go to advanced in twrp main menu and then file manager, goto data and delete cache folder and dalvik-cache folder completely.

7. Reboot system and enjoy

8. if all is working go to twrp again and if you want, install the rr_mod_extras and enjoy.:laugh:
