Hi,

The problem may be with your platform-tools copy. This download worked successfully for my Umidigi A7S: ADB and Fastboot (platform-tools)

With this unzipped folder opened, I launched the Command Prompt and all worked well. If this doesn't work, a DroidWin How-To page may help: https://www.droidwin.com/fix-failed-remote-unknown-command-error

You need this guide:

How to unlock bootloader on Spreadtrum Phone - unofficial twrp

unlock bootloader on Spreadtrum Phone easy method by using the signature.bin, you can unlock any spreadtrum or UniSoc Phone

unofficialtwrp.com

Running Linux script also need to have Linux subsystem for Windows or Linux. The token number splitted to 2 lines. You need to append them to the unlock command.
[Android General] bouyhy01:
Did that already on windows but wont work
[Android General] gunar74:
It was worked on my Power 5s. But I can't remember, how. Maybe on Win11 with it's own Linux subsystem. There is a Linux script, which will not work on Windows, or I tried on Cinnamon VM. But I do not remember, which method was success, sorry. But if you unlock the bootloader, there is no method to root it as far as I know.
[Android General] bouyhy01:
rooting is easy bro just download the firmware and unpack it using the flashtool and take the boot.img patch it with magisk and flash it via fastboot
[Android General] gunar74:
It did not work for me. Fastboot flashing gave error. I think it is not that simple on Spreadtrum (Unisoc) devices.
[Android General] bouyhy01:
The unlocking didnt worked for me i used ubuntu too but wont work got a fail every time trying unlocking with the generated signature.bin , screw that spreadtrum ****
[Android General] gunar74:
Did you use that modded platform-tool? Also the generated token has two lines on mine. The second line was shorter. I appended the second line to the end of the first line for generating signature.bin.
[Android General] bouyhy01:
Yeah sure the linux one and downloaded on hovatek forum and 4pda too , mine generated inly one line , can you help ´ i have teamviewer , ill be gratefull
[Android General] gunar74:
You need that tool on Unofficialtwrp site. This one: https://www.mediafire.com/file/tizx4xbn004ge6f/Platform+tool+Mod.rar/file
[Android General] bouyhy01:
Its the same man
[Android General] bouyhy01:
this is for windows man , im using linux
[Android General] gunar74:
Try it from Windows. I do not have a better idea. :-(
[Android General] bouyhy01:
Dude i already did it 100 tims on w10 and w11 i even installed linux subsystem
[Android General] mark332:
Go with Linux- https://www.mediafire.com/file/xwflbftct62s8nz/Platform+modified_fastboot.rar/file

first set require Permission to downloaded folder then start

./fastboot 'command'
[Android Head-Units] aiesec:
I bought Android head unit from Chinese seller.

And the unit can support 4G(LTE) network and there is a SIM slot for that.

I put the SIM card but the 4G(LTE) network does not work.

The reason of problem, the IMEI number is wrong.

I bought the unit with my friends and the IMEI number of all unit is same.

So I tried to change the IMEI number, but I can't get the root authority.

Then I tried to unlock the bootloader without PC, but I could not.

And I could not find how to connect to PC this unit. When I connect the USB to PC, there is no such a device on device manager.

How can I change the IMEI number? or How can I unlock bootloader or get root authority?

Thank you.

Edit or change of IMEI is illegal in quite a few of countries. For this reason, I've closed your thread! XDA doesn't allow and doesn't accept discussions about or support for such an edit or change.

[Touch GSM General] qaplus:
My company is still using the dying Nextel, and phone they issued is an ancient Motorola. I know Nextel is part of Sprint now. Does it mean I can use any sprint phone in Nextel network? I'm thinking to get an used Sprint Touch for this. Any suggestions? Thanks!
[Touch GSM General] Lokosis:
I don't live in USA, but if I recall right Sprint is a CDMA carrier, therefore you have a Vogue not an Elf, Nextel uses GSM phones (ELF) which is a different technology to CDMA making them incompatible.
[Touch GSM General] qaplus:
My Nextel phone does have a SIM card. I put into a unlocked GSM world phone, but it doesn't seem to work.

Does CDMA phone also have a SIM card?
[Touch GSM General] Lokosis:
CDMA does not use SIM cards
[General Questions and Answers] Sormaus:
Greetings! I recently rolled the dice on an eBay purchase for a Light L16 camera. The device appears to have had some serious OS problems/botched root/adb commands/I am honestly not quite sure what has gone wrong with it, but it is not even showing the OS as LightOS (the camera OS). I was wondering if any of you might have the firmware laying around somewhere, or any experience flashing these devices with AOSP/variants?
[General Questions and Answers] Mike Heck:
I wish I could help. I'm in the same boat with a recent eBay L16 purchase. The one I received appears to be one of the early Beta cameras. It does boot. But the firmware is really old, so the camera won't save any images. I was able to sideload Open Camera, but it just crashes. I'll keep on looking for some updated firmware/ OS. Unfortunately, I believe finding that is highly unlikely once Light stopped all work on the camera and the Nokia Pureview. No one who worked on the project is even associated with Light any longer. Will post anything I possibly locate.
[General Questions and Answers] Sormaus:
Thanks for the reply! I reached out to Light via the email addresses, but I'll be shocked if anyone replies. I tried reaching out to a couple of employees on LinkedIn as well, same result.

I think I got enough information pulled from adb to maybe attempt a LineageOS port. Is your device missing a ton of system options as well? I'm having to hammer this thing through command line.
[General Questions and Answers] Mike Heck:
Yes, mine is missing many options, based on what I know of the camera software's evolution. I had purchased one of the early production cameras back in 2017; since sold it when Light got out of the business.

My unit has LightOS-1,2,2_1 and firmware 428992. The biggest issue for me is the format of the lri RAW files changed over time and can no longer be read by the current Lumen software (can't find the old versions), basically making the camera useless.

I'm not very technical when it comes to Android, so you'd be doing a great service if you can make any headway. Thanks.
[General Questions and Answers] jkrx377:
I've also had this problem recently,,, and it looks like that Light have completely abandoned the maintenance and support for L16, but I think since light L16 is an Android based device, then if we can get access to the firmware for the later models we should possibly being able to try and flush it in. I really don't know much about Android though....Anyway, so I hope that someone can find a solution for this as I really have no clue about it.
[General Questions and Answers] Mike Heck:
I have a production, working L16 with latest software -- in addition to what I believe is one of the early beta units from eBay. I'm not experienced enough to attempt to pull the firmware and software from the working one; all the commercial solutions fail. They seem to require an application to be loaded to the camera, which doesn't work.

I'm more than willing to devote more effort, if someone has a reliable solution, and could post the files.
[General Questions and Answers] CBMUniversal:
I'm in the same boat as y'all. I just received an L16 I bought off of eBay with LightOS version 1.3.0.3-057 and camera firmware version 0039C80D. When I try to update it in the settings app I just get a "You have the latest software, there is no new update available." message.

If someone had the final V1.3.4.1 update files that we could download that would be amazing.
[General Questions and Answers] helloavo:
Hello, I also recently bought one off eBay. Interestingly enough, my error when trying to update is 'failed to query software information'.

LightOS-1.3.2.5-098 and Camera firmware 00624245.

Kernel version 3.18.20-perf-g40a11f1, root@hq-ubandroiddev01 #1, Thu, Jun 21 18:35:48 PDT 2018.

If you have the latest (last) version of the firmware (1.3.4.1) you should be able to 'enable unknown sources' in the settings (see more info here) and then install APKs via the browser. This way you can install any companion app needed to dump the firmware.

It would be awesome to get the latest version.

Edit-spelling and links*
[General Questions and Answers] helloavo:
Update:

Reached out to Light on email and Twitter to see if we can get a offline update image/dump/apk.

Reached out to a few users on GitHub that owned L16 related repositorys to see if they still have their cameras and could create a firmware dump.

Had a look at the Android logs and can see that the updater is trying to reach out to this URL for an update: https://www.c2dms.com/api/v1/SWImage/SystemUpgrade

The website has shutdown by Google on July 30th, 2015, but before then the URL was changed to ota.c2dms anyway.

[General Questions and Answers] Drenathar:
Better than nothing haha. I can always spin up a Mac VM on one of my servers if I don't find the Windows package.

*edit* And I guess that explains why I can't find it posted anywhere if they took it down so recently.

I wish. I'm still stuck on version 1.3.0.6-083 (Late January 2018). I think others are on lower versions than that, but unfortunately I'm new to all this and don't know how to dump such things, or how useful it would be,
[General Questions and Answers] bperryvolatile:
Thanks so much.

I'm receiving brand new ones, no idea the firmware that will be. If I can help get a firmware image off them, I will.
[General Questions and Answers] bperryvolatile:
Does this prevent you from doing anything? Does the Lumen software not support the image format used by this firmware version?
[General Questions and Answers] Mr_Zeeb:
Has anyone updated to MacOS Ventura and Lumen still works? I have Monterey and I’m afraid that if I update to new OS that the program won’t work.

Thanks!
[General Questions and Answers] win32forth:
Be afraid! I have an Apple processor Mac mini, and it will not run the Lumen software. I tried everything, including all the various emulators available. Turns out the Apple processor can't emulate the X86 architecture, or at least it doesn't currently. Sorry to be the bearer of bad news. I had to actually buy a small Windows 11 computer to run Lumen as a pre-processor for my photo processing on the Mac mini. After converting photos to the DNG format, then I shuffle them over to the mini across the network./
[General Questions and Answers] Mr_Zeeb:
I have an Intel based Mac, and the program runs fine on Monterey, so I’m wondering if it still works on Ventura on Intel Mac. I guess I should have specified Intel chip in my original question. Thank you for that info tho.
[General Questions and Answers] win32forth:
Ok, well that is a different story then. My guess is that it won't run directly on Ventura, but it is very likely that you could create a virtual machine with a backup copy of your current OS and it would run in that. The way to try it would be to get Lumen running on a virtual machine first, then upgrade your OS to Ventura. Here is an article on using the UTM virtualization software that should be helpful;

[General Questions and Answers] helloavo:
Just to post an update as I can see there has been some activity, nice to see there are other people interested in the L16.

I have managed to decompile the Camera and Gallery Apps using tools and guides I have found online, the L16 is using Android Marshmallow so getting them to run is proving difficult.

The decomplied apps can be found in the L16 Repo here, really need any Devs that know Java (and in particular Android) to work on this.

I am hoping the .LRI file contains all the .RAW images that are tiled together to create the final image, but I have not found confirmation of this anywhere online.

Edit: Already getting my hopes up

I am going to take apart the Camera and Gallery code in search of the code that save/loads the .lri files, this should give the layout of how data is stored in the files.

I did find this post that suggests it uses Protobuff, this would be great news as Protobuff is easy to work with.

Sunla - I can see you also have pulled the APKs to preserve them, thanks for your efforts! :)

if you are also trying to reverse them you need the separate .odex files for each app (.odex files contain all the code, while the APKs contain the resources like images) and the framework folder too (used for decompiling the .odex files).

If anyone wants to work on this with me just commit to the repo or reach out over Discord: ｈｅｌｌｏ#3197

Apart from breaking open the .lri file, I also want to gain access to the 16 sensors on the camera, hopefully the camera APK will shine some light on how to interact with the custom Light ASIC that controls them all.
[General Questions and Answers] Sunla:
Thank you for the info, helloavo!

I had no idea about the odex files - are they generated by the app, cache or something? I'm not so well-versed in this area, but I'm happy to help any way I can. My time is a tad limited, but I'll definitely keep coming back - I'm really interested in giving new life to the L16 somehow. It's too good of a piece of hardware for its short software support to put a complete end to it. It would be such a waste, it just has too much potential to sit here unfinished like this.

So, how would I go about extracting .odex? Thanks again!
[General Questions and Answers] Polyglotton:
Hi all, been a long time lurker on this post, saw that someone finally got the updated firmware posted, I immediately jumped on and loaded them onto the two cameras I had, and they both took the update no problem. Had to make an account just to say big thanks to @helloavo

Since this does seem to be the only active place L16 owners seem to gather, I had a few question unrelated to the firmware, that I was hoping y'all could help me with;

I got two cameras, out the box one cam had firmware 1.3.0.4 and the other 1.3.0.5, the former has a greenish shutter button light, and the latter a solid blue, is there any other difference between these cams? I have noticed, the 1.3.0.5 has the occasional app crash, not an issue with the other.

Regarding the Lumen software, I also downloaded that from the github, and the end of the install, had a dialog box pop up requesting elevated object something, the box popped up and then vanished before I was able to make a choice, I was able to use the software just fine after that, anyone know what that was about?

Any way to unlock more features for the video app? the 1080p video looks good, but 4k should be possible no? also just want to make sure, pressing the shutter button doesn't record?

I'll have to go back and read everything everyone has found, a lot more info available now it seems.

Thanks again y'all

I recently found this camera on Amazon when looking for a compact mirorrless, would yall recommend picking one of these up if Im willing to tinker but not willing to drop 1k+ on a camera? LOL. Otherwise, how does image quality on average compare with a flagship phone ie. Google pixel 7 pro, or Iphone 14 pro etc...

On the outside looking in, I think the l16 has a lot more to give if more of the software is reverse engineered further, but thats not a given.

Hi, can anyone help me?

After updating my L16, ROOT and TWRP were also installed.

An error occurred while using TWRP because the memory size could not be read.

So some people say that it can be read using format data,

I use TWRP -> wipe -> format data, give it a try

As a result, TWRP deleted the system. How can I save my L16?

Fastboot and Recovery are available.

My English is very bad, so I used Google Translate.

Hello matthew___h,

Do you have the new TWRP?

Because I installed this, some functions are restricted and cannot be used. Is there a complete backup of the system? Because of my L16, Format Data using TWRP cannot enter the system normally.

Final version of LightOS for the Light L16 Camera. Instructions the main repo ReadMe.

This is the update package. My L16 was deleted from the system before and I successfully flashed it back using Fastboot.

PS: After flashing back, you need to LOCK to start the system normally.

I successfully flashed 1.3.0.5 onto my camera.But I can't update it to 1.3.5.1. I followed the instruction,putted the zip file into the camera's internal storage and restart it.Then nothing happens. How can I update it?

I formatted data in twrp thenthe camera cant boot normally.In stock recovery I cannot wipe data.Re-flash firmware is useless.Idk how to recover.
[General Questions and Answers] DSNEAR:
I just refreshed the SYSTEM partition in this way before.

or basic

My previous steps were

fastboot oem devlock off

fastboot reboot bootloader

fastboot oem unlock

fastboot erase system

fastboot flash system "D:\L16\L16 Project\LFC-1351-0-00WW-A01-update\system.img"

fastboot erase recovery

fastboot flash recovery "D:\L16\L16 Project\LFC-1351-0-00WW-A01-update\recovery.img"

fastboot erase boot

fastboot flash boot "D:\L16\L16 Project\LFC-1351-0-00WW-A01-update\boot.img"

fastboot format userdata

fastboot oem lock

fastboot reboot

After the screen reopens, the logo will flash and wait. It may take a while and three circles will appear, indicating success.

These are my steps for reflashing 1.3.5.1

PS. The SYSTEM of the update package needs to be merged into a new img file, which I will attach below.

fastboot oem devlock off

fastboot oem unlock

Thank you for the link. I didn't find any references to John Deere Corporation, but it had lots of interesting information about Light Corp. Also found a teardown web page on the L16, so I made a PDF out of it and attached it for anyone that might be interested.

There was contact information at the link you provided to some people that worked at BTL which is apparently a company in China that may have been manufacturing the L16. Anyway, interesting info indeed.

Oh, by the way, just doing a simple Google search for 2AIQB-L16 yields several interesting things on the web related to the L16.
