[Q] After using the phone -> No connection and phone shuts down

[Tuhoaja]

Alright, I have very strange problem on my phone.


It happens when I browse the internet with my phone. Suddenly, I lose my connection. Then the phone shuts down. When I open in again it has 1-4% battery and still no connection.
I have no idea what the reason could be.
I've tried to change rom but it didnt help. From 4.0.4->4.0.4 (currently)

Thank in advance

I'd like to add to OP that my phone shuts down after long use, I dont have to be at the internet.
Does anyone have any idea?

Moro.

I had SlimICS first, then I changed to XI9000 -style ROM.
But I dont think the problem is because of the rom, as I didnt have the problem first on SlimICS, but then suddenly it just "appeared".

Should I try to change the modem?

 

[Mongopusher42]

Weird.. yes, i would try to change modems, if that doesnt work i would maybe try a re install of the rom.. btw which modem are u using? I want to use xxjvu because i get a better connection with that but i get the roaming sign after installing it :X

I had JVT.
Alright, I flashed JVU now, the phone doesnt turn off anymore. But still it loses the connection, which basicully means I have to restart my phone.

Can you recommend any other modems? (modems that work in Finland)

Well, the one on my sig works good.. but that doesnt sound like a modem issua at all, i think u might have to try and install a new rom.. i wpuld suggest a FULL wipe and sd card formating before u do

Yes, I think you're right.
Im going to flash 2.2/2.3 with odin and format sd-card, after that I will flash again this 4.0.4 rom. If it doesnt work then I have no clue.

Thanks

 

[Mongopusher42]

Yes, that sounds right. Good luck!

Alright..

So I flashed Darky's Resurrection Edition Android 2.3.6 with Odin (repartition+pit+pda)
It didnt help, phone still shuts down.

Now I think Im going to backup my sd-card and try a 2.2 Rom.

could be battery related

Hi,

you've probably solved your problem by now, but just in case, here's what I found researching this issue (I have the very same problem):

This seems to be happening to various phones (although, SGS I9000 and its variants are the most frequent), various ROM and kernels. It is very

probably battery related as the solutions which helped people ease the problem the most were sticking a bit of a bussiness card under the battery

to make contacts tighter, scratch the contacts on the battery itself with scissors or some other metal tool as they have become oxidized through

frequent charging (this significantly reduced number of my shutdowns, but didn't eliminate them) and buying a complete new battery (by far the

most successful solution, although, even this didn't help some people )
