• Upgraded K750i firmware to latest version at Leon Kilat ::: The Cybercafe Experiments // May 29, 2006 at 2:53 pm

  

  [...] (Update: the latest Sony Ericsson firmware is now: R1CA021) I upgraded my Sony Ericsson K750i to the latest firmware version last night. The new firmware, R1BC002, fixes a lot of bugs and offers several enhancements to the phone. My phone’s previous firmware, R1N035, was three releases behind and still contained bugs. [...]

  im not able to upgrade the firmware using the update service. my phone switchs ‘on’ when i connect the data cable while pressing the ‘c’ button and nothing happens afterwards. wat could be hte problem

• Max Limpag // May 31, 2006 at 6:28 pm

  

  Krishna,
  Did you restart your computer after you installed the Sony Ericsson Update service and update drivers?

• Renante Nate // Jun 2, 2006 at 4:18 pm

  

  krishna,
  if you cant switch off the phone, then remove the battery.
  Make sure the computer detects your phone before you run the update. In windows XP if you plug-in the cable to a different USB port other than the port you had installed into, it will scan for driver again.
  If pressing and holding the “C” while connecting the cable, a pop-up message appears in the rightmost bottom taskbar detecting the hardware. In this case, you havent installed the driver and you need to install the driver.
  Restart the computer and run again the update.

• Worried // Jun 5, 2006 at 7:54 pm

  

  naah, its still going on. the window says updating software with do not touch the phone flashing.

  i think there is some activity happening ‘coz the ma3platform.exe process (looks like the process under which update service is running) is active and is constantly showing me increasing I/O writes.

  I am keeping my fingers crossed though, don’t want to have a phone that does not function and head to the service center instead of work tomorrow morning :p

  Anybody help me

• the KG // Jun 12, 2006 at 4:24 pm

  

  bro. its good to bump into your website… i have been having the same trouble of missing files in my file manager…

  when did you purchase your phone? i just got mine last week. anyway, will its warranty be void if i upgrade the phone’s firmware my self or should i have it upgraded where I purchased it?

  do you think they’lll know if i upgraded its firmware?

• Max Limpag // Jun 12, 2006 at 7:28 pm

  

  KG Jun,
  will its warranty be void if i upgrade the phone’s firmware my self or should i have it upgraded where I purchased it?
  I don’t think the warranty will be void if you use the official Sony Ericsson Update Service that comes with your phone or in the Sony Ericsson website. If you just bought it, you can have it upgraded for free from the Sony Ericsson service center. Just tell them you’re having problems with USB transfer with the current firmware.

• the KG // Jun 13, 2006 at 8:49 am

  

  hehe…its only KG(jun is from the date posted)…but thats OK…

  Thanks for the help Max, I will be going to Ayala Cebu sometime this week(theres a service center there right?), or, I could still use the USB and upgrade it myself…I don’t know…

  By the way…more question…
  1. How old is your phone?
  2. I have the oldest version of the software(R1N035), could this mean its old stock, maybe recon? whats your insight on this?

• Rox // Jun 13, 2006 at 10:30 pm

  

  I need help with the updating of my software, it’s been updating for more than an hour even thought it’s 100% and it still shows “updating software”!! what should i do.. is there a problem with the Update service software?

  This is the point i’ve been raising ever since but nobody discussed it even the SE customer service.
  How do you know the manufacturing date of the phone? Definitely much earlier than your purchase date. Everytime you update your fone, your IMEI has this two digit suffix. The higher it is, the older your fone is.

• Max Limpag // Jun 14, 2006 at 2:49 pm

  

  KG,
  Sorry for that mix-up. I got my phone early this year and it came with the R1N035 service. If I were you, the easiest way to upgrade would be to let the Sony Ericsson service center in Ayala upgrade it. It’s covered by a warranty, tell them you can’t use it as a music player because files aren’t transferred properly to the memory stick because of the firmware bug.

  If not for this blog and my weekly column on cellphones, I would have let the service center do the upgrade. I needed to do it myself so that I could write about the experience.

  Jawad,
  I’m still researching but have you tried running the upgrade again. Delete all the Sony Ericsson Update Service files, uninstall the program and delete its folder. Better yet, try using another PC to run the update service again.

  I haven’t been experimenting with the phone lately, it’s the World Cup and I lack sleep

  Max

• jensen // Jun 14, 2006 at 5:50 pm

  

  same prob as strcmp, but i found a solution in another forum: when your update service stuck with the message “Please do not touch the phone” and progressbar @ 100% SHUT DOWN your computer (!) and after that unplug your phone. it’s working, my k750i starts normally and my firmware is now R1CA021. good luck, hopefully it’ll work for you too.

• Jon // Jun 16, 2006 at 6:59 am

  

  Well dudes, I just upgraded with to the latest firmware with their poorly coded peice of crap updater that took about 600 attempts to download the firmware from the server.

  I thought SE were the good guys?!

  All works though. But now I have this annoying bug where my phone switches off after the backlight goes off. If I play with it though (keep it from the backlight going off) it stays alive perfectly.

  Freaking annoying.
  Any Ideas?

• c. Aquino // Jun 21, 2006 at 4:32 am

  

  Dear Max,
  Pre, can you help me, My xp will not recognize the phone when I plug itin, no new hardware found message, I also tried all usb ports no luck and also downloaded and unzipped the USB driver from SE site, is there a particular folder that I need to extract the USB driver to? the phone Icon at the bottom does not show up either, only activity happening when I plug the phone is that it turns on while pressing c button and phone is indicating that it is charging mode. I have also restarted my PC many times, and there are no removable mdia found it the device manager section as you suggested. Problems - battery drain so fast 5hrs. only , new bat and new charger still same. thanks in advance

• Max Limpag // Jun 29, 2006 at 2:55 am

  

  jensen,
  Thanks for the tip.

  Jon,
  That IS annoying. I’ll post here if ever I spot a solution.

  C. Aquino,
  Sorry for the late feedback. World Cup games are keeping me from getting enough sleep.

  Have you been able to solve it? When you encountered the problems, was the Sony Ericsson Update service already installed? As far as I know, there isn’t a specific folder that you have to extract the USB drivers to because you can just point to the folder when the new hardware wizard launches. I’m not sure, though, why the wizard won’t launch in your setup.

• bong nate // Jun 29, 2006 at 9:52 pm

  

  Hey,

  Can anybody discuss how to use the k750i to connect to internet i.e. surf in your PC/laptop using k750i as your modem. SMART has this promo of unlimited internet for only P10/ 30 min.
  Smart Customer Care is inutile to explain their own promo.

• cindy // Jul 14, 2006 at 5:08 pm

  

  i upgraded my fon with the latest firmware R1CA021.
  actually, the update said that the upgrade of the software failed. Yet, when i checked my fons version, it changed. the 1st change i noticed was if i adjust the volume, i could no longer see the volume bar. how come? i really need some help.

• lakmal // Jul 26, 2006 at 1:30 pm

  

  How to download the latest firware for k750i?
  I search through the internet but no link for the download.What is the link for R1CA021?
  Anyone pls help me.

• Max Limpag // Jul 26, 2006 at 2:10 pm

  

  Lakmal,
  What you need to download is the Sony Ericsson Update Service. This software downloads the latest firmware for your region. You can find the download link at the end of the article above.

• Naveen // Aug 10, 2006 at 4:46 am

  

  Hi,

  I had bought a K750i 3 months back.Previously i was using the software version R1BC002 which came with the phone. It was super and was working well. Today i thought of upgrading to the latest version by SE R1CA021 - (UpdateService_Inst_2.6.4.9). Well the installation went well but after updating my phone i found that a bit of sound has been increased, which is very good for the phone speakers, but for the head phones it hurts. I think that the phones can’t withstand that much bass and might damage my head phones.

  Previously in R1BC002 even when i raise the volume to 90% it was very clear and the bass was very good. Now after i have installed the new update i see if i increase the volume i hear lotta itching sound in the head phones. I think SE have made some (a slight increased bass) changes in that section. It is really bad. My phone is just 3 months old

  Also i noticed that when i start my camera, i saw that the picture did not cover the full screen…(notice that there will be thin space above and below the screen which will not been covered.) Previously i was getting full fledge picture on the screen, not now after updating.

  This is really bad. These SE people are experimenting their softwares on us friends…..So friends, i am planning to rollback to the previous version that i had (R1BC002) which is superb. Please help me how and where can i get that software and how to uninstall this version (R1CA021).

  Please….please help me…..
  Any suggestion and advise will be appreciated.

  Thanks in advance
  Naveen

• Emajr36 // Sep 5, 2006 at 11:46 am

  

  Hi there Max. Your site here is really great. I just wanted to know if you’ve encountered this problem of mine about the photolight or flash of my SE K750i. When I turn it on, it just takes about 2 seconds to lit up. And then it goes off. And it does not light again until such time. And it goes that way until this time. What seems to be the problem. i hope that you could help me with this. I can’t take pictures on dim places w/o the flash. What can you suggest on this problem to be fixed. I got my phone about a month already. Thanks and God Bless!!!!

• Thanh Tam // Sep 9, 2006 at 7:00 pm

  

  I just upgraded my Sony Ericsson K750i to the latest firmware version: R1CA021.However, My language - Vietnamese - no more in my phone. How does it set Vietnamese language for my phone? Thanks.

• Max Limpag // Sep 13, 2006 at 1:11 pm

  

  Naveen,
  I haven’t been able to find ways to roll back to the previous version. Let’s just hope SE will release another improved firmware.

  Jason,
  I’ve upgraded my phone using Windows XP with Service Pack 2, I encountered problems at first but I remember solving it by restarting the PC.

  Emajr36,
  I rearely use my flash. In fact, I can’t recall using it in the last 5 months or so. What I just do is use the cloudy setting for white balance and make sure there is enough light when taking photographs.

  Thanh Tam,
  I have no idea how to do this but when I spot a solution, I’ll email you.

  I’m putting off updating until I get the technical details of what’s in the new firmware. All indications I get so far is that it’s just a minor bug fix. Thanks for the alert, by the way.

  Benny,
  I don’t know what seems to be the problem as your firmware version is so far behind the software update program should be pushing you the new version. What country are you in? Where did you buy the phone?

  Max,

  Im from Manila, i bought the phone in greenhills. I’ve tried is so many times but to no avail. I’m getting quite desperate to get the latest firmware to the point that im willing to pay just to get it. Im not really having problems with my current one but havng the latest firmware is just so tempting. Any suggestions as to how i can get it without having to go thru SEUS or DaVinci?

• Max Limpag // Oct 19, 2006 at 4:20 am

  

  Benny,
  Was this phone by any chance unlocked by technicians? Why not try asking the shop where you bought the phone to upgrade the firmware for you because the R1NA005 firmware still has the USB transfer bug. Tell them about this and try asking that they update it for free.

  To get your phone’s firmware upgraded, you either need to go through the Sony Ericsson update system or a third-party updater such as DaVinci.

  Flashdancer,
  Try restarting your pc and running the update service again. Also, please check your USB flash driver.

• Vikrant // Oct 21, 2006 at 12:39 am

  

  Hey guys… I sucessfully upgraded to the latest version R1DB001.. but found the music player has been made very bad in this release… Can anyone tell me how to rollback to the old firmware… From where do i get it and how do i flash it………
  An advice for all those guys who are yet to take up flashing part: if u use ur phone majorly as mp3 player then plz dont upgrade to the latest firmware..

• Max Limpag // Oct 21, 2006 at 12:46 am

  

  Vikrant,
  Thanks for the warning. I have been thinking of upgrading to the latest version not because I need it but to record the steps for a tutorial.

  What did they do to the music player? When you say very bad, do you mean the quality of the audio or the way the music player functions?

  Rolling back to an older firmware seems to be a lot of work, based on what I’ve read so far, because you can’t specify which firmware to use for your phone.

• benny // Oct 21, 2006 at 2:58 am

  

  Max,

  i bought it 2nd hand thats why there’s no warranty. Where could the problem be? Is it my phone or my SEUS software?

  Before, my concern was browsing the internet using k750 as gprs modem. The smart promo is a great help though disappointing most of the time because of slow bandwidth.
  But now i enjoy surfing the internet with k750 at broadband speed using the DSL connection of PC. Top softwares i use are opera mini (web browser), Google Map ( satellite map viewer), KJV (entire bible), customized dictionary. The connection is via bluetooth or cable.

• bongnate // Feb 1, 2007 at 9:41 am

  

  ken,

  there is this java midlet MC2Lite.jar that looks like a spreadsheet. Search for it on getjar.com
  I guess it would only be useful if you create a simple spreadsheet on PC for read-only access to your mobile phone. The connection may be over WAP.

• Max Limpag // Feb 2, 2007 at 2:48 am

  Hi Max,

  I have not tried downloading any excel attachments from my fone as i have been busy playing around with it. I successfully changed it to a W800i but i noticed the volume of everything from earpiece to external speaker went down and now the camera wount take pictures. I have CDA: 102430, Europe 2
  Firmware: R1BC002. Any comments on this?

  I am thinking of flashing it back to k750i with R1CA021 Firmware but topsony have not sent me the confirmation mail for my account for two days now so am stuck. When i use SEUS it says I have the latest software so i guess i have to wait for topsony or do you know where i can get this files on the net, a trusted free site?

  rico,
  As far as I know, the official Sony Ericsson update service will upgrade your phone to the latest firmware. In the k750i’s case, it will be the the much maligned R1DB001. Maybe you can try unofficial and third party software to update your phone to R1CA021 but it could be risky.

  Hi,
  MY PHONE IS AUTOMATICALLY SENDING MESSAGES!
  My name is Brett from Australia
  My new k750i has firmware R1CA021 and it recently acting strange. It was been automatically sending txt to an unknown number, my phone company tells me this mystery number is not active, adding nothing to my bill. But every hour of so i’ll get a message on my screen ‘ Message sent’, but no copy of what was sen in my sent items or outbox. My phone company tell me it could be a software issue so have refered to to Sony Ericcson. SE have told me to install the lastest firmware as a possible fix. Just wondering if this is wise of if anyone else has experienced this problem or is this a virus?

  I tried updating the firmware (through the website and all) but it says, “Update not available” then “The software in your phone is up-to-date” I know the last time I checked its the old firmware

• Max Limpag // Dec 6, 2007 at 1:17 am

  

  Guys,
  There are no more updates for the Sony Ericsson K750i. Sony Ericsson wants you to buy their new phones that’s why they’re stopping support for older phones.
