problem with LG Optimus T

[match417]

I haven't upgraded from the stock rom yet, but I'm considering it because it seems like I have a firmware problem. I got this phone new off of ebay a few months ago. At least every other day, the phone keeps saying "SD card unexpectedly removed, please insert a new one". It happens when I haven't changed card. I don't even have to touch the phone and I'll see the screen come on and say "sd card unexpectedly removed..." I have googled and I saw others experiencing the same problem. This is one thing that is keeping me from upgrading to a different ROM. I'm worried that if I change roms, maybe the internal problem with manifest during the procedure and brick my phone. Is this a concern that I should have? Or should I proceed with changing ROM's?

My other question is if someone else with this same phone has experienced this problem before, and did the problem go away when the ROM was changed?

Yeah, I just picked up one of these off ebay, and... the pins on the SD card slot are pretty bad, I dunno if that helps exactly but maybe something to check for...

Manger .. got clock work recovery and did a backup of my rom .. than I flashed mik cm7 .. never had those problems again ... and didn't. Have the problem were my phone restarted on it's on ...

oh yeah, my phone restarts on it's own too. I forgot to mention, I assumed it could have been a bad connection leading the phone to not read the SD card, then read it, then not read it. It has a cheap looking lock-down mechanism that doesn't look like it would let the phone read the SD card all the time. So I cut a little piece of paper the size of the SD card and stuck it between the lock-down latch door and the card, it didn't fix a thing. So I ruled out a bad connection.

So blackrose, you had the same probs I have now and yours is fixed? I'll look up the mik cm7 rom and install that, are there different versions of the mik cm7 rom? If so, which did you choose?

Check the firmware version on your phone. Older firmwares had that issue, but I believe they were resolved in V10L and newer revisions.

You can go to LG's website and get the download link for the newest f/w version for your phone by putting your IMEI at the end of the address:

csmg.lgmobile.com:9002/csmg/b2c/client/auth_model_check2.jsp?esn=INSERT IMEI HERE

You have to use KDZ updater to flash it.

!! disable LG modem in computer device manager !!
make sure you have msxml installed
set type to 3GQCT
set PhoneMode to DIAG
Select the downloaded firmware file
sit back and WAIT..

I run linux on my laptop, I used to have my laptop dual booted when I had my hd2 so I could change out my roms but then I sold my hd2, had no use for windows so I deleted the partition. is there a linux version of the updater i need? or can i install the kdz updater through wine? does kdz updater run solid enough in wine so I don't have to worry about bricking it? I'm going to sell this phone for whatever I can get for it on ebay and I want it functional. I'm picking up another hd2 tomorrow for a great price.

i just tried going to the lg webpage you mentioned and I got a weird error. My IMEI is 012408001118364, and it says IMEI SV is 03. this is the exact link that I typed in my browser, I copied it and posted it here when it didn't work.

my phone has gotten worse in the last couple weeks. has anyone tried to see if it's just a faulty SD card? the problem has to do with the sd card, the phone says it's removed when it wasn't. I have an old 2 gig one somewhere that I'll put in it and see what happens. also my version is V10L

 

[match417]

what do I need to put a different rom on my optimus t? and would it be running off of the SD card like I had to do with the HD2 or can it just run off of the internal memory?

my phone works perfectly now. I checked for updates and I have the latest update already installed on it, it's what came on it, V10L. So I deleted some apps off of the phone to clear up space. I grabbed a different 2gig SD card, formatted it with the phone, transferred all of my old stuff from it off of the other card that was in it and put it in the phone. Now I have had it running flawlessly for over a week. I don't know if it was the samsung SD card that was in it that was faulty, or if it was doing that because there were too many apps on it. I know some SD cards are junk, I don't know about samsung, the one I put in it is older but it is a kingston. I didn't have to root it or anything. But I still want to so I can delete some of this crap thats on it from when I got it.

So since this phone is linux based, how do I get to the terminal so I can su root or sudo. And what is the root password? I want to control this thing!

So maybe the problem was that I had too little space left on it, or maybe the problem was that the SD card is junk.
