Hi you all,
I have a Gemini PDA 4G
My PDA is set with multiboot --> root android 7.1 ---recovery --- linux --- TWRP
Believe me, I do not know where I make error for a correct upgrade to have 8.1 android.
Just to know, if my steps are correct I write below what I did:
1. downloaded a news scatter file + base firmware (root android 8.1) + additional KALI or DEBIAN file
2. under linux start the FLASH TOOL
3. I choose the directory with inside all new files and the new scatter file
4. Choose FIRMWARE UPGRADE - click on DOWNLOAD -- connect my PDA
5. everything work fine
BUT
I have 2 problem:
1. under LINUYX system NVRAM error under wifi connection (and the problem already reported in other topics of no saved wifi password)
2. under TWRP no possibility to mount DATA / NVDATA
There is something wrong in my steps ??
Thank you
CRI
Unfortunately you can't get 8.1 from flash/partition tool and download for rooted android, It did not work for me, check out the flashing without changing userdata here:
http://support.planetcom.co.uk/index.php/A...d_Manual_UpdateYou can follow this then you will keep your linux and user data. I did not found any use for TWRP with multiboot, tried to update magisk from it and nothing happened, it wrote done, and magisk kept the old version. Similar with rooted android, I flashed it and it is 7.1.1, well possible i used wrong image, will retry with another.... So I think you need to go details file and download the latest
from their site support.planetcom.co.uk/download/AndroidFirmware/Gemini_x25_x27_FOTA6_06052019.zip I am not sure why flash tool suggesting the older firmware, just noticed when wanted to upgrade rooted android....
Edit: After flashing even i did not touch boot 2,3 and linux image, it no longer bootable . I have no clue what happened, I reflash only the boot now still nothing happen boot loops, and hope I don't need to overwrite the linux, but it seems it is a must :S Android working fine after reflash all apps remain and upgraded in few minutes. Might be a small glitch with the scatter file, as i created a new one with 28,28 split same as i was using before the upgrade, so linux need to be reflashed now...
