I'm using Ninji's images which I flashed by using SP Flash Tool. It would be really nice if someone could upload the new boot (Magisk patch installed) and system images to somewhere again. Otherwise I don't know how to flash the update because the installation by using the official flashing tool fails. I don't know if the OTA zip file is flashable via fastboot?

There is a new version of firmware today ( ota update ) . I've rooted android the unnoficial way following the steps in this forum. But this firmware update from Planet didn't install ( error ). Can someoone help ? Thank you.


You need to unroot your device first, obviously. I haven't tested the process myself, but you need to essentially install the original boot image via fastboot. Then boot, patch, and re-root (you need to create a new rooted image or wait for someone to publish one here).

OK. Thank you . I will try.

Just did the OTA upgrade myself. Process as documented in my earlier post - just "fastboot flash boot boot_orig.img" and then patch as normal.

To get back root, you need to use sp_flashtool to grab the image off it, then use magisk manager to re-patch that image, and then flash it using fastboot again. I haven't done this yet.

I just selected the rooted android version in the boot menu & it appears to be rooted and working as it should smile.gif

I was wondering if someone could help me. I was trying to be smart by deleting google system files off my cosmo. When I try to apply the v20 patch it fails. I have downloaded the system dump files from post 83 and when I try to restore my cosmo from the scatter files it is missing some files. So far I have been able to resolve some of the error I am getting but I have hit a road block. I seem to be missing the bin files for scp1, scp2, lk, lk2, logo, tee1, tee2, cache and userdata. If I am able to restore without these file please let me know.

Thanks in advance.

Regards

Mibry


Reply to my own post. I was able to fix my problem by using fastboot to restore the system.img file from the dump that was done by Ninji. Thanks for the dumped files.

Replying to my post: I was able to update from rooted V19 to V20 by re-flashing Ninji's V19 images and original (unrooted) boot img using SP Flash Tool. Then I did the upgrade manually by putting OTA.zip into phone's storage root and flashing it by using PlanetCom's update tool in Android (accessible via Settings). Upgrade was OK now. After that I re-flashed the rooted boot img provided by PlanetCom.

Installed the original image. Updated the firmware. Did a boot in Debian and extracted the android boot image.Copied it to a folder in android. Did a boot in android and patched it with magisk. Copied the image to my computer and did a fastboot to flash the new patched image from magisk. Worked !
