C902 Problems

I have a huuuge problem with my C902.
Not sure what firmware it is, but I found the phone and I assume it's imported from India, mainly because of the arabic writing on the keys.

I can't check the firmware because, everytime I start the phone, it lags a while to find service, seems fine for 10 seconds, then goes blank and seems to reboot itself, repeating the process over and over again. When this happens the only lights that are on are the keys and the camera button.

I don't know what to do. I've tried switching SIM cards, manually taking the battery out, and even tried shutting it down before it rebooted itself.

What do I do?

Try the Sony Ericsson Update Service. You can download it from the Sony Ericsson website, and once you've done that, follow the instructions the program gives you. That's assuming you have a USB cable for it?

Yeah I tried the service, and it's installed, but it won't start up on my computer.
I'm running on vista, and I don't know why that won't work as well...

That's weird. Sometimes SEUS does take a while to start up... Have you given it a good 10 minutes to start up? Or does it just fail straight away?

Posted by iromey
It doesn't even start up, period

Ok, well that's the only suggestion I can offer other than flashing it via davinci, but that will cost you.

Totalgsm would be an option too. But none of the online flashing clients supporting 3150 phones like yours are free...

You still have warranty on your phone, if you have problems, why not use it? The SE-update dont work on vista 64-bit so far.

My phone has been acting up after having it for a Week! Turning off and on randomly and vibrating! I tried to do a master reset, BIG MISTAKE! cause now the phone is stuck at the screen please wait for the pasted 5 hours i have tried everything i found through this website google and i called SE themselves to ask and they said do a software update, tried to do that the computer cant read the phone! im soo frustrated cause i spend 370euros on it in a dif, country and SE told me its out of warranty now cause i bought it from a dif country and i have to pay 100 bucks to send it and get it fixed! Something help me try to figure out how to fix this phone before i loose my mind!

Would recommend you to flash the firmware of the phone.

Posted by aremaboy
Yes, it is always recommended that you perform a full or total flashing via Sony Ericsson Update Service (SEUS) if you have any problems---in this case may be related to firmware or software issues. The case like frequent restarts or glitches here and there may be overcome by overwriting the whole Main Firmware and File System one. It's free, you just need to have a good internet connection and a healthy Windows-based PC as long as your CDA is approved by SEUS server.

a lil off topic point id like to make
just cuz it has arabic writing doesnt mean its from india lol...they dont even speak arabic in india..so ya
tis kinda funny to me...i dunno if u wrote that on purpose or unknowingly..no offense at all though

SEUS doesn't work on Vista, so I tried using it on an XP computer, and the problem with the phone connecting to SEUS, is that it doesn't even stay on long enough to update. It just continues to restart over and over again.

yeah how can it be from India if it has Arabic text?
phones from KSA have Arabic text but phones from UAE usually don't have.
or maybe that's Hindi(Indian lang)on your phone.

anyway why don't you go to your local service center and ask them to re-flash your phone?
i don't think that costs much.

surely your phone should be OFF during any updating using SEUS? you connect when asked but you press the "c" key while plugging in the data cable

Posted by iromey
But the phone TURNS ON to update after holding down the 'c' button and plugging it in.

Ok, the main point is that the phone simply restarts no matter what way it's turned on, e.g. through updating or connecting it through the computer.

Posted by Muhammad-Oli
That's weird cause the phone shouldn't turn on to update it. It should stay turned off.

Do you hold down the 'C' key until it tells you to release it?


Posted by foggy_lad
reflashed my own yesterday and SEUS told me to charge battery fully then turn off and take battery out! then put batttery back in and when it asks you hold down the "c" key while you plug in the data cable ant it will connect and tell you when to release the "c" key and the phone stays off!

are you sure your power button is not stuck?? this might explain if the phone was continously restarting?


Posted by iromey
Okay, there's nothing wrong with the phone's power button, and i've done all that battery bullshit, holding the c button down and whatever but you're missing the point.

NONE OF THAT WORKS.

So, I need to find out WHY the phone constantly restarts. It stays on long enough to connect to the network each time and then cuts out. I managed to reset the phone entirely and that still did nothing.

IT SIMPLY DOES NOT STAY ON, PERIOD.
Not even with the 'c' button held down
Not even when I try to update it
Nothing! =[

We got your point dude. We were just checking you had done everything right. You'd be surprised at how many people don't know how to update their phone or need step-by-step instructions all the way through.

Do you know anyone with the same phone? Or at least the same battery? Try swapping an identical battery into your C902 and see if it works then. It might be that your battery is screwed.

Posted by strizlow800
Battery might be the problem aswell. Or it may need full flashing with Totalgsm or other online flashing clients, which are not free you know.

Posted by ricen00dles
Also, you can try holding down the "2" button rather than "c" when attempting to update

This was the case with my w880i...

Posted by TimeWriter
Better hold the "2" and "5" buttons when connecting to SEUS.

Hi im new here, I just flashed my c902 to R3ea038 via SEUS. All went smoothly. After flashing, I checked that under Customisation info there is a weird string 1E0W. How can I get rid of that string? It didn't exist before I flashed the phone. I took out M2 card and SIM Card prior to flashing. My battery was 100 percent full. And also will i able to update my firmware again in the future on SEUS with this "1e0w" string? Thanks.
