[Q] My i747 won't start at all!:( topic

Hello everyone,

My at&t galaxy s3 would not turn on at all after I messed around with some apps called "Aparted" and "Swapper 2".. If there is some way this could be fixed I would really appreciate it!

So the story was..

I was reading some forums and their guides on how you can add more RAM and use an ExtSD to an Internal SD.
So I got interested and decided to do the guide to see if it will really boost up my phone. So I downloaded Aparted and Swapper 2. I then I wiped and partition my ExtSD to 3 partitions. 1 formatted to Ext3 for the swapper to use RAM, 1 formatted to ext4 for the Internal memory. And 1 formatted to Fat32 for my computer to read.

I thought it was a good idea since it will boost up my phone.

But then when I stared the swapper 2 to start using the partition for the RAM, everything went smoothly and the app said it was set successfully and asking to reboot. So I did. After the phone turned off to reboot, it usually takes 2 seconds for it to vibrate and start booting but it was completely dead and not responding to the power button. I could not even go to recovery mode or download mode because the buttons do not respond. When I connect it to a charger and the battery removed, it only lights up a red LED and when I try to put back the battery it only goes away. I've tried various things to boot up my phone. From waiting to removing the battery and wait, when putting it on a computer which only reads QHSUSB_DLOAD, downloaded the qualcomm drives which now reads HS-USB diagnostics 9008 and leaving the phone on a charger for a day to no avail. If anyone could try and help without me sending my phone to a JTAG or anything that would make me spend too much money..

Thank you for taking your time reading my post.

Unable to Change Bootloader (accidentally installed wrong bootloader) Galaxy S3 I747 topic

Hello everyone,

I'm trying to install the latest Cyanogen Mod, but when I do, I get an assert error. I figured out through research that this is because the newest versions require an updated bootloader. So I naturally found the latest bootloader for my model and pushed it to my SD card to install it. However, when I try to install it with CWM, I get an error saying "You cannot flash from your current bootloader version. Current version: T999UVDLJA (Status 7).

I must have stupidly installed the wrong bootloader for my device? The strange thing is that my phone is a t-mobile phone, or so it says on the back, but the "about phone" section of my settings tells me it's the model SGH-I747, which is ATT. I bought it used, so I have no idea which it actually is. My question is, how do I change my phone's bootloader to the newer version so I can install the latest CM?


Thank you in advance!

[Q] T-Mobile wifi calling on i747 topic

My family recently switched to T-Mobile and another family member had my S3. I remember a loooong time ago I installed a i747 ROM that was a tmobile variant port and when I first booted with the rom it said something about tmobile wifi calling not working (because I'm on AT&T). If I wanted to get tmobiles wifi calling on my i747 S3 is there a method or rom that offers that? I tried searching for the rom I used before or a thread about this but I couldn't find one :l

[Q] AMR-WB (HD-Voice)? d2att | i747 topic

Bottom line is I'm looking for a way to enable AMR-WB codec. I'm on T-Mobile now.

Is support for AMR-WB in the CSC file?

If so can some make a custom CSC file for i747 that enables HD-Voice (AMR-WB)? I have an unlocked i747 with a SHG-T999L ROM, and baseband i747CUEMJB.

Any help is greatly appreciated.
