Rollback to OS 3.5

robdx2

I am wanting to roll back to OS 3.5 and I have read everything I can find about it so I am a bit nervous to do it. I am not 100% sure I actually will do it as yet, but I want to be prepared just in case, can someone who knows check my file structure in the picture please

I have read when rolling back you have to do a full factory wipe or the launcher will not work, so in the structure shown on the picture I have downloaded this file from this forum which is release OS 3.5 Global_DUDU7870_2412221316_2412031108 and extracted to the root of a Fat32 USB drive as shown in picture. I have removed the files from the "Factory Reset" folder and placed them on the root, Is that all I need to do for the factory reset and wipe all launcher data?
I have added the lsec-downgrade file as circled in the picture
I have removed the lsec6318update from the downloaded 3.5 and replaced it with the lsec6318update from the latest 3.6

So can you tell me if this will safely downgrade to 3.5, factory wipe and leave me with a fully working 3.5 and launcher??

Yes, this will revert to 3.5 and erase the data.

DUDU-Meng Thank you, and by erasing all data will the launcher work ok after the downgrade?

DUDU-Meng

robdx2 Sure, no problem.

DUDU-Meng Thank you, I do feel that 3.5 is more stable, plus I much prefered the menu layout in 3.5, Is there a way to add a button in a future release to swith between 3.5 menu layout and 3.6 menu layout?

DUDU-Meng Hi, how close are we to a new update a 3.7 beta?? I am still deciding if to roll back but if a new update is close I will wait for it....My 4g is having problems now, the sim slot could have a fault as it wouldn't see the sim card, had to unplug and replug from the back of the unit

robdx2 Let me know how it goes as I may do it if you are successful. I have been hesitant because of a lack of clarity in the instructions but it seems you have a good grasp on it.

robdx2

Jetskiz I will if I go ahead, Initially I have reflashed 3.6 to see if it improves things
