I want to upgrade my Ericsson T28s, how? - GSM-Forum

Borzo_ITA · 09-11-2006, 08:25

I'd like to upgrade the software of my old mobile phone (Ericsson T28s), but I don't know to do! I know I have to find the cable but I don't know if I have to modify it. And what is the software that I have to use? Where I can get it?

Sorry for my crappy english...

Hi and welcome.
T28 updating isn't very difficult.
The only things you need is a PC running WIN9x (NO Windows XP support), a flash cable and a little prog called ATR.
You'll find

atr_serv_50.exe

atr_serv_52.exe

atr_serv_53.exe

atr_serv_53_bat.exe

here. It's equal which one you choose.

And now you need the newer flashfile for your phone.

Which you will find here.

What is the newer flashfile? I mean... there are a lot of files and I don't know the one to download! help!

It's quite easy to read the codes of dates on old flashfiles:

They are often named xxWyy like 00w03 which means the following:
xx (in this example 00) is the year -> 2000
yy (in this example 03) is the week -> week 3 -> between jan 15th and jan 21th
So the flashfile is given out between jan 15 and jan 21 2003.

Other files are named xxyyzz like 990831 which has to read this way:
99 is the year (1999)
08 is the month (august)
31 is the day
so a flashfile called t28_990831.r2a is the flashfile for T28 revision R2A given out on august 31th, 1999

The third way to recognize which is old and which is newer version is to look for the Rxy part of the name, which tells you more about the revision version.
R1A is the first one, R1B is the second, later firmware version are named R2x or R4x.

t28s 00w03.shx (week 3, 2000)

t28_990831.r2a /revision R2A from 31. august 1999

t28s_00w26.zip (week 26, 2000)

t28_01w07.zip (week 7, 2001)

t28_in991022.zip (22. oktober 1999)

t28_01w26.zip (week 26, 2001)

Some more informations are sometime placed in the name of the file like this one: t28_r4be1.sbn

firmare: t28
revision: R4B
language: e1 -> Europe_1

Europe_1 should contains the following languages:
Bulgarian(BG) Croatian(HR) Czech(CS) Danish(DA) Dutch(NL) English(EN)
Estonian(ET) German(DE) Greek(EL) Finnish(FI) French(FR) Hungarian(HU)
Italian(IT) Latvian(LV) Lithuanian(LT) Norwegian(NO) Portuguese(PT)
Polish(PL) Romanian(RO) Russian(RU) Serbian(SR) Slovenian(SL)
Slovakian(SK) Swedish(SV) Spanish(ES) Turkish(TR) Arabic(AR) Hebrew(IW)

BTW. the last T28s firmware is revision R5C which should be the last from 2001.

I've read that the newest one is 010627 but I can't find it on that page... Where I could find it?

If it's difficult to find on the net send me an email with an attachment to borzowsky@gmail.com
Thanks!!!

It's quite easy to find. Just look out for the file called: t28_01w26.zip . It is, like before mentioned, the t28 flashfile given out on the 26th week in 2001. Now it's up to you to take a calender and look, when is the 26th week?

Yep, it's in june! Right?!

Borzo_ITA · 09-12-2006, 16:51

I found the firmware you suggested in the other thread... Thank you so much!

Does any of that software linked to work with the T18d specifically? I really badly need software for reading/flashing this phone! Please help before I have to resort to desoldering EEPROM chips to use a replacement phone!

Legas · 09-29-2006, 20:09

Varan should work with 'standart trick', but I'm not sure...I killed one new T18s, that wasn't detected by any software.
