22L, 23L
25L
26L

Unpack, rename to 'firmware.bin' and put to the root of your memory card.

[flatline]

is this safe/tested and working f/w?

[nutsey]

Yep. I successfully updated my Z22 cam, other versions are also reported to work at 4pda.ru forum.

[flatline]

worked on my Z26L too. let's try yimax script

[ZeroFPV]

So finally... I got to update my Yis too. Might be the final firmware for all Yi action cams I guess.
I'm sorry that I couldn't test scripts the last days. There wasn't sun at all here an I've been busy too.

1.5.6, Z26L. Pink photo. Everything is done according to the instructions. It seems like I've been told that this method for SONY matrix and need for Panasonic.

[Hekpresents]

found! https://www.goprawn.com/forum/main-f...r-z26l-yi-cams

[ZeroFPV]

There seem to be some changes in 1.5.6 when it comes to scripting. I just made a memory dump to look into.

Bitrate table and resolutions are shifted again. Setting the video mode with "writeb 0xC06D4426 0xXX" does still work.

[nutsey]

Didn't noticed any changes for my Z22 rev. I know there are differences in Linux partition but I don't think they are worth to mention.

[ZeroFPV]

Might be different 1.5.6 firmwares for Z22 and Z26...


On my Z26L I tested the Superview script and i got [email protected] instead of resized 1600x1200 --> 1080p @ 35Mbps

I already found the new table location in the memory dump. Just need my old z26 dump to calculate the amount of shifting.

In my memory dump of [email protected] the table starts @0xC05C8E50

[nutsey]

Yes, the memory offsets have changed for superview and 4Gb limit.

[ZeroFPV]

bitrates, min bitrate, max bitrate, recordingmode are shifted by h1000 compared to firmware 1.4.8

So the new address for the bitrate of videomode 0C (1600x1200p60) is 0xC05C9092 instead of 0xC05C8092 in firmware 1.4.8.
resolutions are shifted by h1000 too...

EDIT: Just tested with the Superview script. :-) To find the clipping setting again is a bit more tricky.

0xC03AB4A0

[ZeroFPV]

:-D
Ok. I'll make updated textfiles for 1.5.6. and attach them to the other thread.

[MacGyver]

Is there's any superview + flat color script for fw 1.5.6 z26L ??

[nickxab]

Hello
I'm owner of a Z25L model and currently i have the firmware V1.2.13 so i can run scripts.
I use the XIMODE 2.1.0, is a script with many scripts including your's nutsey.
If i install the v1.5.6 can i use those scripts ?
Thanks in advance.

[nutsey]

Hi. 1.5.6 firmware has somewhat different memory structure, so if you want to use bitrate, 4gb limit or superview related script features you need to use updated scripts (I posted them before). And by the way I have nothing to do with XIMODE

[details03]

I've received my Xiaomi Yi Camera today (brand new) and it came like this:

What can I do?

[nutsey]

Have you tried to put a microsd card in?

[details03]

Yes I have

Is there a recovery kit for a z231...?

Hey Nutsey,
I have a Z25L version of the Xiaomi Yi with the stock firmware (I believe it's 1.4.3), and I want to improve the quality of the image.
Is it possible to run the Yimax Pro script on the Z25L version of the camera with 1.5.6 firmware version? I would like to know this before I ruin the camera, or change the firmware without being able to improve the quality as I also can't find the 1.4.3. firmware to undo the changes in case it doesn't work. Can you, or anyone else who knows, help me out with this please? BTW, a different script that will increase the bitrate is fine too! I have used the Waffle script on my old Yi and was very happy with it, but this one doesn't work either.
Thanks in advance!

[nutsey]

Hey Darko,
Try this script to backup your original firmware: https://drive.google.com/file/d/0B4t...ew?usp=sharing

Put it to a memory card, turn on your cam, wait until the camera switches off, fw will be saved to backup.bin file.

Note: You will not get flashable file with this script. It only saves all the partitions of firmware into one file. There is still a need to reconstruct the header in order it can be flashed from memory card.

This FW bricked mine 25L.

Now it behaves like this:
https://www.youtube.com/watch?v=BdFhBZlNFSs
Tried to reflash it with yiActionCamUSB app, but after 5secs (not 50+) it says "Done", but no progress...
I can see it does something (generates folders and files on the uSD), but still keeps restarting.

[nutsey]

What file are you trying to flash?
There is another tool for Ambarella chips: https://www.goprawn.com/forum/main-f...update-from-pc

[DigY]

The one from your first post for 25L or one I got from Xiaomi Tech.

Update:
With AmbaUSB installed, the HW is found as board 3.2.1.0.

A7L selected (the program recognized it as A7La).

Then the program waits for reboot, but the camera does not reboot and message:

disconnecting form PC aborts programming...

[nutsey]

I see. The firmware I posted here was flashed with success by dozens of users.
What steps do you perform when flashing it via USB?

[DigY]

1. disassembly front panel of the camera
2. run the program
3. selecting A7L
4. selecting the FW
5. connect the cam to PC (no battery and no uSD)
6. short the resistor to GND
7. Turn on camera (keeping resistor shorted) - by pressing the power button
8. after 1-2secs, remove the shorting wire
8. Press download.
9. after the message: Initialize BusID#003.DevID#009 successfully! I have to disconnect the cam from PC and reconnect. And turn on with all buttons pressed (it seems it goes to a mode that is visible to the program). Then the program automatically continues the programming until a message: Transfer finished successfully! Near the progress bar it is written: Waiting for reboot. But nothing happens...

Pressing any button does not help, disconnecting from PC aborts programming. I have no idea how to force reboot.

I have also tried force flashing via autoexec.ash
"firmfl prog firmware.bin > progress.txt
rm firmware.bin
rm autoexec.ash
poweroff"
but it goes max to [4l...

With this method the cam generates some files:
nvd.0 and nvd.1 and progress.txt
and folders MISC (itm.bin inside) and DCIM

[Xiaomiau]

hi there,

I took the

26L

and did
Unpack, rename to 'firmware.bin' and put to the root of your memory card.

And now it goes bip bip bip - bip bip bip - bip bip bip - bip bip bip - bip bip bip - bip bip bip - ovver 5 minutes now - how long I have to wait and what to do now?


Cheers....

EDIT: UPPS forget to unpack!... now its better....

[jyowy5]

Hi, this is a simple firmware update or is a firmware update with script?

[nutsey]

The 1st one.

[jyowy5]

Thanks, I wait for the script

[nutsey]

What kind of script do you wait for?

[jyowy5]

For bitrate (35mbps) and flat profile

[nutsey]

Oh, that script. YiMAX-PRO scripts for 1.5.6 are here:

[Mdissoky]

Hey Nutsey,

I have YI cam Model Z22L it is bricked can you send me the ELF files for the latest firmware, it tried flashing it before with ver 1.2.13 but it didn't work

Regards,

[nutsey]

Hi,

I don't have any ELFs for the latest firmware, but I have older 1.2.6 for Z22L. Have you tried flashing it?
