Infact, ver 500 is the easiest one among these 3 version.
The sms format sent from the unit to your server is !-0000,[server addr],username,pwd.
I have successfull result for ver 500 v3.02.171, v3.02.172 and v3.02.172. All upgraded to V3.02.158VYJ005.
But this ver. Doesnot work for V3.22.187.
i have successful result for ver 500 v3.02.172 and v3.02.184. All upgraded to V3.02.158VYJ005 through OTA
but this software not support at my platform. so the tracker not send valid location at my platform. can't change time zone. still TIME ZONE:E00:00
this software only support at orange server

Firstly, thank you very much to those who posted the solution here, the files and make the youtube video! Everything helped a lot!
I have successful result with a TLT-2H V3.02.184F4 2012/09/17. Upgrade to V500 V3.02.158F4VYJ005 using an old mobile phone data cable with PL2303. The connector of my TLT-2H is similar to the battery one. Since only 2 vias are needed (tx/rx), I solve the problem using 2 little wires to connect. The GND I connected to the black supply cable. It works fine.

Just wait and see, hope the updated firmware will be released soon
Yes, I think there are still bugs in many update versions.
I have 1 unit that updated to V4.02.250F4 suddenly stop sending data (even to orange server) after 1 day successful upgrade. tracking can only be done using 6660000 sms command.
V600 v4.02.247 is even harder to upgrade (to V600 v4.02.250). I have only 2 success OTA updates out of 6, but 1 of them stop sending data to orange server after 1 day.
I think the company or anyone making this tracker before must help much more on this issue.

this keeps chasing me! I had succes in updating OTA on V500 units, but some of them have fallen back to their original firmwares. I think somewhere the units are storing the original firmware and in some situations this is re-flashed in the unit. It happened after successful test and correct position information. Maybe it is because the unit is checking the firmware version and sees it has newer version in some part of its ram/rom?
The version it happened to are: v3.02.184F4, v3.02.172.
I have flashed 1 unit again but now with cable, and this is working for some weeks now.
Does anybody know how to prevent the unit from re-flashing their original firmware?

You can fix the issues from this blog,include the firmware and upgrade tools:

You just repeated the old story except for this statement:
'Mictrack have upgraded TLT-2N to MC300 and it’s more stable and same functions, commands. Best choose instead of TLT-2N, contact us: firstname.lastname@example.org'.
Could tell us more/share with us about this MC300?
Mictrack MC300 is a re-design(include hardware and software) and similar functions and commands as TLT-2N. As you know the TLT-2H/2N is famous in Brazil and Peru, now some of my clients have switch to MC300 to instead of it.
This is the user manual for MC300: https://www.mictrack...Manual_V2.0.pdf

yes, you can download the firmware from the ending of the blog, pls check again.

I dont understand what file of firmware you refer to. I cant find it. What i mean is the mc300 firmware that downloadable which you claimed more stable than tlt2h.
And also I have one question, is this Company producing mc300 was actually the one that produced tlt2h before? If so, please help us to provide more stable and hassle-free solution for this 'new year, mess.
We are still desperately hoping that some one eventually will come up with bullet proof solution.
Hi Unicar, the the blog download is the later firmware for TLT-2H/2N,not MC300. If your firmware is not on the list, leave us your message and we will help you check.
