Capturing and inspecting OTA firmware updates

Operating Systems Android
1

Dunno if this will help anyone, but today I captured an ota link to inspect firmware. Need usb debugging, but no root necessary.

Linux:

adb logcat | grep -i 'http'

Windows:

adb logcat | findstr /i http

Go to system updates and search for update, press ctrl+c on the terminal when it starts downloading.

Take your output and dump it into an ai agent, ask it to find the update link. Or, ya know, you could sift through it yourself.

Should be able to download the firmware from that link.

I was thinking maybe someone would do this for the Kyoceras.

Use Payload Dumper Go to extract the firmware once downloaded.

2

You can unzip it in WinRAR to see all the partitions

3

You can unzip a payload.bin in WinRAR?

I’ve always used payload dumper go

4

Maybe it downloads in different formats for othr phones, but for the TCL updates WinRAR worked

5

I’m not to familiar with the Kyoceras.. but if TAG made custom firmware for them, and stock firmware is not online, I believe they must have started here…

Which Kyocera phone does TAG do this for? Does it have fastboot (before they do their process)?

6

For example, I just did this for the E4810

That’s the only Kyocera phone I have. No fastboot as far as I’m aware, but I don’t know much about these.

Seems to have edl though.

7

There is source code online somewhere

8

Some source. Maybe some kernels. Someone posted a link a while back.

Not firmware.

9

Flash through qfil

10

I’d have to look into it. Never used it. Has anyone ever rooted these phones?

11

I used it for orbic but you need the correct firehose

12

I’m assuming those are not available

13

wonder if firehose can be extracted from verizon upgrade assistant…

14

Is that what Purifone did?

15

No idea

Qualcomm stuff is all new to me, aside from OnePlus devices.

16

Tried installing it. All I was able to extract was fastboot drivers.

If I was actually able to run the exe, I might find something more… Maybe in tmp folders.

Anyway, the program does not run normally…

17

This is another option for extracting if you don’t have a pc:

18

Here is a firmware link for E4810 for example:

https://cdn2.vzwdm.com/Kyocera_E4810_1.402VZ_1.502VZ.bin

Their server is:

https://cdn2.vzwdm.com

If the firmware for other phones are on this server, you can play around with the path.

20

What firmware do you guys want :slight_smile:

Currently running for E4810 and E4811

21

Can you do anything with it?
Is there any way to flash anything?
