Xiaomi Yi Custom firmware with lastest revision

Hi,

@Mighty777 : thanks for your help but unless I am mistaken, I can't use another firmware on the model Z25 than firmware 3.0. Just downloading it (and put it where then by the way? into the sd card?) doesn't work. what model do you have?

@TwoBlues : what model do you have?


Thanks for your help,
 
I have an original Z22L..., and an international Z231....
but I don't recognize a fw other than 1.2.13 from Yi in Jan. this year.
are you meaning the first Yi and not the new 4k?
 
Hi TwoBlues,

You have too Yi Sport Action? I have the first Yi but I can assure you that there is a firmware 1.3 ..
 
Currently, like 30 secs ago on Yi fw update website latest firmware is v 1.2.13 for the original 2k Xiaomi yi
serial numbers listed: 22, 22L, 23, 23A, 23L and 23S. I don't know other than this!

Hi! Cannot you download firmware 3.0 (for your camera model Z25) and then open it with Ambarella Toolbox?
 
Hi Mighty, I actually already have Firmware version 1.3.0.
The highest video resolution setting mode I have is 2304*1296 30P 16:9.
But the few video I shot, especially when inside my house and low lights were not very good quality.
I wonder if I can do something to improve it ..

Hi Hugo, I believe you can. Have you tried to use Ambarella Toolbox and modify the firmware to allow higher bitrate? An higher bitrate, which is not necessarily introduced in a newest firmware, is an "hack" which can improve the quality. Unfortunately, the color balance of the Xiaomi Yi (and of the new Yi II as well) is not great, and a bit too "warm and greenish", but it can be corrected in post-processing with the most common video-editing softwares.

Cheers!
 
Hi! Is there an existing script for delete the THM files generated by the cam for every video? Thank you.
 
Go to the yi 2k cam category and open the Ximode 2.1 which writes script for things like superview for the original cam. It deletes the thm files if I understand the instructions.

Yes, but the Ximode is not for free, also I would like only to delete thm files, or add simple scripts, I don't want to modify other things.
 
Yes it is .If you go the last page a forum member has alink. Page 11, I think!
 
I made changes from 0x420C to 0x41C8 but still records in 35Mbit. Same thing on Stock and custom firmware. What i'm doing wrong?

#2304x1296p30 35Mbit
writew 0xC05C1EB2 0x41C8

#1080p60 35Mbit
writew 0xC05C1EE2 0x41C8

#1080p48 35Mbit
writew 0xC05C2452 0x41C8

#1080p30 35Mbit
writew 0xC05C1F72 0x41C8

#1080p24 35Mbit
writew 0xC05C2492 0x41C8
 
Hi !
I am very new to this (Xi arrived today), so i have 2 Questions:
-Can i use the modded FW together with Ximode ?
(Does it make sense ?)
-i found references to a higher res mode 2500x... is that possiboe, did not find it here ?!

Thank you and GREAT work anyways, already MUCH better with high bitrate and less denoising 🙂

And I'm looking for a writ Fw1.2.13 for resolution 2560x1440 PAL, not NTSC
 
Hey,
I have the problem with this firmware that sometimes it just records a few seconds. And when my SD card is half full it is not recording anymore and just freezing. Anyone else with this issue?

SD-Card: SanDisk Ultra MicroSD XC I 64GB

Is there anywhere a firmware without thm files and about 25Mbit?
