I tested the unsealing on Mavic 1 battery I have, and it was working. Why it didn't worked for you - I don't know. Maybe unseal key is different, and maybe the issue lies somewhere else.

[mjnhchj]

that's right. I can't do it with my MM battery either!

[mefistotelis]

When you figure out the cause, make sure to share.

I used this tool https://mega.nz/file/yEJGwJYR#O3jh40agtSWE11HRySdg5C6X5y2OeHW2c_A4hOcCVFs All work fine with CP2112 adapter

hello everyone, how good there are enthusiasts who can embrace almost anything. this topic helped me check out some AIR 1 batteries that I managed to buy some time ago. However, I have a problem with sealing. The program presented here does not have this option, but it is in the last screenshot. What is this version, because visually the interface looks identical, it is probably a newer development version. There is a chance to get access to this version? I have one more question. Has anyone tried to replace cels ( mavic AIR 1) with more capacity, but not 18650. I am asking because I noticed repeated damage that the last cell in blocked batteries has reversed polarity and cannot be regenerated, charged. Thanks in advance for any suggestions.

[mjnhchj]

That software is "DJI battery killer" by Mixeysan developer! It will release soon ...

I have not finished everything yet. In particular, still need to remove the unnecessary and disable to write of FW BQ30Z55, because the CP2112 adapter will not be able to do this anyway. But the change in capacity, voltages, charge max, reset of cycles seems to be plowing both on bq30z55 and on bq9003. To get full access in BQ30Z55 when the key is unknown, use the Full Access button. There are still small shoals, with time I'll correct it. And I'll release it a little later when will be free time)

During the test, repairing the firmware in BQ9003 when the EEPROM is empty - FFFFFFFFF. The chip is always in bootloop. See video http://master-club.org/drone/BQ9003_bootloop_repair_empty_EEPROM.mp4

Hi Mr.mixeysan
when i open the program an error message is not found file mfc140u.dll

Check your files or system. You are the first who wrote about such a problem

[0roblequad]

Hola Sr.mixeysan comprando el adaptador cp2112 como debo conectarlo a la batería del mavic2 alguna imagen como esta

[0roblequad]

donde conecto el sda y scl en el pc2112

[SinisterRj]

@0roblequad Usually the boards came with those pins labeled. Check with your cp2112 vendor. (you must connect gnd pin also)

hello, is possible unlock BQ30Z55 DJI RONIN MX 1580 BATTERY? dji not sell this battery, ronin mx is an obsolete product... so i have tested your software... and run well, read and write, but battery after unseal, clear pf, and seal don't charge... can I collaborate with you for develop a new version for unlock dji old gimbal battery? best regards

Hi. Please write me via telegram, I'll try help.

[davidhaluska]

Hi All, Is there possible to put battery into sleep mode - as when it comes from factory? There should be some command for that or? Thanks. David

[Alessandro2023]

Good afternoon friend I would like to know if you managed to finish the dji battery killer 0.4 beta 2 if you were able to finish it could you give me the link to download it in my email please ale3dprint@hotmail.com

[cptrock]

Can a FT23RL chip be integrated with your app? Both windows and linux

Hello, I am using raspberry to unseal mini 2 battery, but without luck.. SEC=3 anyway

[ledo77]

Hello, same here

[gdereck]

Same here (tried on Raspberry Pi 1 & 4). I managed to unseal and unlock my DJI Mini 2 battery using the "Arduino Battery Crack" software from Battery Killer's support channel and an Arduino Uno. I can't tell why that one works and this doesn't.

Hi gdereck. Could you please provide more information on the process with the Arduino. Maybe share a link to the tool you used? I am also having problems using the Raspberry on my Mavic 2 Enterprise Zoom Battery as it will not unseal.

I recon that Mixeysan is having other problems at the moment than helping out people on the internet with the Russians attacking his country. :( Hope this madness is over soon.

[gdereck]

Hi gdereck. Could you please provide more information on the process with the Arduino. Maybe share a link to the tool you used? I am also having problems using the Raspberry on my Mavic 2 Enterprise Zoom Battery as it will not unseal.

Mixeysan posted an invite to their support channel in #245. I joined it and downloaded software posted by Chi on May 9 I think. It's a hex file you need to upload into your Arduino and an exe you run on your PC with Arduino connected. Note: it's closed source and it's hard to tell what it does under the hood. I ran it on a VM just in case. Use with caution, at your own risk.

I've also seen that someone posted an Arduino sketch - may work as well. That support channel is a good source of information. Good luck!

Thanks gdereck for your swift reply. Sadly it seems that all download links in the support forum are dead. I guess I'll have to buy a pricey cp2112 board and use the battery killer software :/ It's really hard sitting there with a dead enterprise edition battery.

You don't happen to still have the hex and exe files you could provide? Never the less thanks for your response. Best regards

[gdereck]

The download works for me (iOS Telegram client), I've just downloaded them. I don't feel comfortable distributing someone else's software but if you don't manage to get it to work, I can try.

[bornsnyder]

Seems I got you wrong about the support channel. I tried the link he posted in the other topic you mentioned (4dpa forum with 160+ pages in the thread) .. I just tried to contact via the t.me link provided in the abouts of the battery killer application but I'm not feeling comfortable contacting Mixeysan directly while ukraine is attacked - me asking for help with my shitty drone battery.You get what I mean. :/ Would be much appreciated if you could help out but if not I totally understand.

[gdereck]

The point is that you can join the Telegram group and see the entire conversation history. It includes files posted by Mixeysan and others. If you want to find the files I mentioned, just scroll up to May 9th and find Chi's post. Or use the search feature and look for arduino battery crack.exe. There are many people in that group and lots of information in the history. It seems that an arduino-only open-source alternative is also available (DJI Arduino.zip), but I haven't tested it.

[gdereck]

Would be much appreciated if you could help out but if not I totally understand.

To make sure there are no misunderstandings: I meant the Telegram group invite link he posted on Feb 27 in the issue mentioned. The group has lots of members and many files you can download. You'll likely find the right tools there.

https://github.com/o-gs/dji-firmware-tools/issues/245#issuecomment-1053563653

[gdereck]

@bornsnyder, you could try this: https://github.com/o-gs/dji-firmware-tools/issues/232#issuecomment-1166430849 That custom key seems consistent with the DJI Arduino source code. I haven't tried it though.

[bornsnyder]

@bornsnyder, you could try this: #232 (comment) That custom key seems consistent with the DJI Arduino source code. I haven't tried it though.

Thanks but already tried that without success ..

Now I finally managed to find and join the support channel and download the exe and hex file. (I was literally blind) Now I just need to figure out the wiring :D Thanks again for your help.

[Happilytrying]

Hi everyone. I tried to reset 3 spark batteries using Texas Instruments battery BQ studio but the chips for DJI spark do not seem to be in there it’s the BQ30Z55 I need right? I tried some others like BQ27 and Bq40 but the options don’t allow to resent PF and unseal codes don’t work.

with DJI battery killer the software doesn’t work with EV2400 I’ve tried (unless there is a driver needed?). Should I get hold of cp2112 adapter, and will it work with battery killer and spark chip ok without knowing the unseal code?

or is there another software for EV2400? I see TRB pontoon lab but it’s a paid subscription

Thanks for the help

[kloppinc]

I am also unable to unseal a bq40z307 inside a mavic air battery. Anyone has the correct key?

[goliady]

I used this tool https://mega.nz/file/yEJGwJYR#O3jh40agtSWE11HRySdg5C6X5y2OeHW2c_A4hOcCVFs All work fine with CP2112 adapter
