How to Change the IMEI Number on Your BraX3

I’m regretting getting the BraX3. I wish I had just donated to the cause so that the BraX4 might be a product worth getting*

*If you have a dual sim and want to use BOTH of them, and if you’re super happy with the regular AT&T service with 6 months remaining in a yearly prepaid setup, and have tried t-mobile and found it doesn’t work, then the BraX3 will be a HUGE, a GD MAJOR time suck. Don’t get the BraX3 if you want something that works out of the box, and if 40+ hours of setup is not up your alley…

I was one of the most patient backers, even chastising folks for being upset with the delay’s. I said stuff like “dont spend the money if you can’t imagine them not following through” and “have patience, it’s coming, it’s a lot of work”, but now that I have it, or should I say have HAD it in had for months now, it STILL is a paper weight and not functioning. I’m so disappointed. Brax man said “This will work on AT&T. It might need a small thing here or there to make it work, but it will work.” I’d have to say, PHOOY. it works if you have another phone to rob IMEI numbers from, so why bother getting a second phone???

Ok, so I got to this thread: How to manually install or update your OS on your BraX3
Great, I learned how to put IodeOS on a phone with IodeOS already. But that’s a good lesson on flashing the phone. So I took those steps and applied it to the above linked LunarOS. This also worked well. From LunarOS, I was then able to change the IMEI numbers with the SN Writer Tool. This worked fine. I then went back an reflashed IodeOS. And I infact have different IMEI numbers then what I started with. This is seemingly great, and the desired result. Just be sure to only select “Download” within SP Flash Tool when reflashing IodeOS from LunarOS or else it will wipe the IMEI numbers and you’ll have to redo the above steps (NOT ‘Download & Format’).

Ok, so it seems like I’ve got what I want. But the IMEI numbers I used from 2 of my old ATT phones will only work for physical SIMS, not the eSim. Somehwere on AT&T’s end, when I called to switch the esim from my current phone to the brax3, they said it wasn’t possible, and that IMEI number will only go onto a physical sim, not an eSim. Seems like the IMEI is identifying the phone and other info that AT&T sees as ‘not compatible’ as an esim. Maybe someone else can shed light. But at the moment, they can not switch my esim. And this is my last hurdle after months of learning de-googled processes… to even see if it’s working and what i want. WHAT A HEADACHE!!! I only have so much skill in this department. Should I just go back to the stock IMEI and see if AT&T will switch the esim to that, even though it’s not “an approved device”? I originally threw my physical sim and it worked, but I got messages from ATT that said otherwise and to call tech support. Which I didn’t do because I’m under the impression they won’t help…

Is there no way to just generate a IMEI number that will work, or should I go hawking ebay listings and steal some IMEI numbers there and screw over the future purchasers?
