Convert your N73-5 RM-132 to N73-1 RM-133

Note:The N73-5 RM-132 is a Non-3G variant of the N73 while the N73-1 RM-133 is a 3G variant and supports 3G in WCDMA 2100 Band.

To convert your N73-5 to N73-1 to support 3G you will need a CA-53 USB Data Cable,Nokia Phoenix Service Software 2007(2006 might also work) and a RM-133 Firmware.

Follow the steps mentioned below:

1]Plug the USB connector of the CA-53 Data Cable to your computers USB port but don’t connect your phone yet.

2]Install the RM-133 Firmware

3]Open Phoenix Service Software 2007 and click maintain and add new user.

4]After adding details select the user and click OK.The Phoenix main window will open.

5]Now choose file menu and click on Open Product.

6]Select RM-133 from the list and click on OK.It will take some time to load since the phone is not connected.

7]Choose the flashing menu and click on Firmware Update.

8]The Firmware Update window will appear but since the phone is not connected it will take some time to load.

9]In the product code section select your product code.For eg APAC 1 or APAC 2,EURO 1 or EURO 2.

10]Now connect your phone to the PC by the CA-53 Data Cable and select PC Suite mode.

11]Click on OK in the Firmware Update window of Phoenix.Now after it verifies connectivity with the phone it will restart the phone and start flashing.Don’t touch the phone while the flashing process otherwise you have the risk of a dead phone.

After this you can also change your N73 to N73 ME by just changing the product code via NSS or manually downloading the firmware and flashing it.

Backup all your important data such as contacts and messages before flashing.

You can void your warranty by converting your phone but it is not yet confirmed.

If you are a noob at flashing phones then please consult me before flashing.

If you don’t have a CA-53 cable then you will need to purchase it.It is available at any Nokia shop btw it also comes with every N73.

  1. This is not a smart idea because once you have flash you’re N73-5, You won’t be able to switch back unless you have the firmware. if you go forward with it, it will completely stuff up the phone because the N73-5 doesn’t support 3G which requires a special chip in the phone. Only the N73-1 and N73 ME supports 3G.

  2. It is not a good idea. Just by updating firmware from RM-132 to RM-133 doesn’t make your Nokia N73-5 3G enabled. If you update your firmware to RM-133 then your phone will work like N73 ME and it will also install all the features of N73ME but when you try to change the network to dual, the phone will restart and again it will show the network as GSM. This I am telling because I have N73-5 and tried all the possible way to convert it to 3G enabled but could not succeed. So, I would like to tell every body that if anybody purchase N73 new or refurbished then please do the following process Menu-Tools-settings-network and select dual or UMTS mode. if the handset convert to the dual or UMTS mode then it is 3G enabled otherwise not. N73-5 doesn’t have network option by default. IT will appear only when you upgrade the firmware to RM-133.

    Dear phuchungbhutia,

    Pheonix software have an option to flash dead phone also. Just try it. The softwareis free available in the net.

  3. Mates anyone read the book CPALead Ebook, I found it to be the bank. “CPALead Ebook Money 2010” – search google for it . Hope you find it and start making bread

  4. I just now came through Yahoo and got to take a few mins to say many thanks for the good ecommerce program product reviews that you have on this site. I will be sure to take them into consideration further.

  5. Фрукты обдать кипятком, положить в морозилку на 8-10 часов, а затем опустить ненадолго в горячую воду (чтобы фрукты лучше поддались нарезке) после этого нарезать на кусочки и прокрутить через мясорубку.
    Прокрученную массу залить 3-мя литрами холодной питьевой воды.
    Через 15 минут настой профильтровать, сначала через дуршлаг, чтобы убрать крупные кусочки, затем через сито, чтобы удалить мякоть, – (отходы не выбрасывайте, они вам еще пригодятся).
    1кг. сахара растворите в 2 литрах теплой воды.
    Долить в отфильтрованный настой еще 4 (четыре!) литра воды и 2 литра, получившегося сиропа.
    Дайте настояться еще час и всё! Лимонад готов.
    Перелейте в красивый кувшин, а остальной в бутылки. Все поставите в холодильник.
    Если вас испугает столь большой литраж, уменьшите количество ингредиентов наполовину.
    Но я уверена что, попробовав этот напиток, вы будете его готовить еще и еще.
    Лимонад получился очень вкусный, освежающий! Я взяла половину нормы, выход у меня получился 5 литров.
    Отходы можно засыпать сахаром, и довести до кипения – получится варенье.
