Messed up badly: Firmware upgrade encountered an issue

[chris_j11]

SGH-I747M rooted, but still original rom
Carrier - Rogers
Device type - d2can
Bootloader/Baseband/PDA- I747MVLDLK4
Modem board- MSM8960
CWM-based Recovery v5.5.0.4

i've been wanting to install cm12 rom on my phone for the longest time and this morning i decided to jump into it (i did spend time reading some info here and there and getting advised getting the matrixzone rom)

my first mistake was i decided to unlock my bootloaded with ez-unlock - this caused my phone to hard brick

i found a link in XDA section ([HOW TO GUIDE] How To Unbrick AT&T I747 and I747M After 4.3 OTA) to help me boot back to my phone from my sd card

then my second mistake - used another link in XDA section ( [HOWTO] [ROOT] No Tripping Flash Counter - [ATT / Bell / Telus / Rogers / Sasktel]) above to download the stock Rogers 4.1.1 and load to Odin

Started Odin and it failed right away - now my phone will only go Odin mode with "Firmware upgrade encountered an issue" messages at the bottom

I was informed to go to sammobile to download a newer firmware (not sure which one) and try again with Odin

i decided to download the latest Roger version 4.4.2 - still waiting for it to finished

anyone else can provide help will be very much appreciated = thanks in advance

In order for ODIN to connect to your device you'll have to put it in DOWNLOAD MODE:

1. Unplug the USB cable.
2. Shut down the phone.
3. Hold down the 'HOME' + 'VOLUME DOWN' buttons and press the 'POWER' button for about 2 seconds until a WARNING! Screen appears. Press the 'VOLUME UP' button to enter Download Mode.
4. To get out of Download Mode, simply press and hold the power button until the phone restarts.

yes i'm in odin mode

after i press volume down+home then power it gets to warning and ask me to press volume up

i tried a higher rom 4.1.2 -Odin Fail!
I will now try a much higher rom at sammobile - 4.4.2

Are you attempting to flash a stock ROM?

 

[chris_j11]

well sucess - download the latest sammobile 4.4.2 and used Odin to install.
after 30mins my phones back to normal
thanks for all the help - now i'm more confident

now i will try to root / install cwm / and continue with matrixzone w/ a twist - hope to have a better result

In the same boat, after nearly trying to flash my phone, it suddenly went to the Firmware screen...
