Hi Plamen, Do you have instruction to do this with a Linux OS/Ubuntu? I do not run windows and need to change the IMEI when I get my Brax3.

This is a really nice guide, we should start a tracker for requested and in progress documentation.

No official guide yet. We’re looking into it.

That’s a good idea. I guess for now just open a new post with a request for documentation.

@plamen I saw another reference that this is not working under iodéOS, has anyone actually successfully reset IMEI?

My situation: in trying different test builds, etc. with SPFlash, I accidentally wiped my IMEI. I have them listed in a text file. When using the tool (W10 64bit, firewall disabled, newest driver installed - I even installed W10 on a spare laptop just for this :-), I do the following:

  • Start the Tool V1.2463.0.0 (as listed from “Help > About”
  • Set settings as described.
  • Click start, entering IMEI 1 and 2, and “OK”
  • Output: it says “Start searching preloader com port and handshake…”
  • Plug in powered-off phone, it does detect and display “META MODE” at bottom for a second
  • Output: it says “Start searching kernel com port and handshake…” and just stays there. No more progress.
  • After another minute or so, it goes back to the IMEI entry window (both are empty). No “FAIL”, no nothing. Just sort of “gets stuck”.
  • I found in the logs, C:\SN Writer\, this message:
ERROR: SP_BROM::SP_GetUSBCOMPortWithFIlter(): enum kernel comport fail(1042). (SPexc.cpp:1060)

Possibilities / Questions:

  • The link to the specific SN Writer tool download doesn’t work for me. I just got the “newest version”, V1.2463.0.0 (as listed from “Help > About”
  • Should be bootloader be unlocked? I have tried both ways, I think the same errors :frowning:
  • Other ideas?

Yes, not working currently. Need to flash to LunarOS > Change IMEI > Flash back to iodeOS. We have someone working on fixing it. Hopefully will be working soon.

@plamen - thank you, I have been banging my head on this from all sorts of angles (winxp / w10 / etc). I didn’t realize the installed system would come into play, I thought this was sort of “below” whether I had iodéOS / LunarOS / or simply “no OS”.

I would like to test wifi on LunarOS so this will be a good excuse. Can you point me to the builds, the guide doesn’t seem to have any download links.

@brinerustle was able to provide a download of LunarOS. I was able to install it, then was able to successfully flash my IMEI back to the phone. Now back on iodéOS again with IMEI in place!

@plamen I know you are busy but I would recommend giving a big warning on the SP Flash guide on the how to upgrade your brax3 post to NOT use the “Format ALL + Download” if you are installing / updating iodéOS since it isn’t possible to re-insert your IMEI afterward.

Fair point. I clarified it in the documentation.

Here is a download link for LunarOS. @plamen if you have a more official hosting location for it feel free!

Additionally, @plamen the link above for SN Writer download isn’t working, here is were I got it (just took the most recent one): https://snwritetool.com/

After flashing Lunar OS from your download link onto a Brax3 I get a constant red text in the upper left hand of the screen saying “userdebug”. It’s kind of annoying, I guess it’s a debug version of LunarOS?
BTW in LunarOS I was successful in changing the IMEIs.

Yes so it seems (that is all I could source from the team to try)

Great! I know at least one other person (@Ricmar ) that is trying this and having trouble with the setup environment.

Can you comment on replaced IMEIs, did you change so you could attempt to get on the Verizon network (USA) by chance? That is a goal for this other user.

How can I get their official release when it comes out? Do I have to subscribe somewhere?

What I would do is find a google pixel, write down the IMEI, change the second to last number of the IMEI, then use an IMEI calculator to calculate the check number (very last number of the IMEI) and use that to flash onto the BraX3.
Maybe check that Verizon was working on the google pixel first. Basically you just have to find an IMEI number that was working with Verizon and use that.

I have the same “userdebug”. I have been using Verizon on my GOS Pixel. I intend to use that SIM. Both pixel IMEI’s are written down. I just need to get the missing vcruntime140.dll file so SN Writer will work.
s25712308, did you have any issues with that? I’m using Win10 64bit.

18

Did you also write down your original brax3 IMEIs in case you need to go back?

OK sorry, I did forget I needed to get the vcruntime.dll too!

Don’t you just love Windows? :slight_smile:

19

I do have the original BraX3 IMEI but don’t think I will be going back.

I didn’t have any issues installing the SN Writer from the link above on Windows 11. I think I even installed it on Windows 10 before.

Nooooo I don’t love Windows. Yes, original BraX3 IMEI’s are also written down. Also took pictures of them and the pixel IMEI’s.

So it’s this pc. It said when I got it, there were no updates available as I did setup. Oh, yes, and then there’s the strange switching of the Ctrl, Fn keys on the keyboard of the Lenovo ThinkPad I got, why on earth did they do that!!! My fingers don’t work well on that layout for copy paste :face_with_raised_eyebrow:
