HI,
i've been wanting to root and install custom roms on the i9003. i finally got the courage to try to root and do all these things recently, so i rooted the phone using superoneclick.. but i didnt know what to do next, because i wanted to try out custom roms because of what i have been reading on the forums.
so i followed the instructions here: http://forum.xda-developers.com/showpost.php?p=19442301&postcount=1 and flashed the bagaria.tar found here using ODIN.
but it started looping and kept rebooting over and over again. and got stuck in bootloop. eventually it came up and would respond a bit before going back to the booting sequence, and i noticed that opening CWM automatically sent the phone to booting.
thinking that i did something wrong and afraid that i bricked the device i went to this thread and looked for the dxkp9 stock and used odin with it (http://forum.xda-developers.com/showthread.php?t=1004647)
it just is stuck on boot loop now.
i've tried removing the battery and trying holding the VOLup home and power to no avail.
its just stuck in boot loop.
It is currently stuck in boot loop and wont do anything. i am really hoping it can still be fixed.. a bit of a sentimental value since this was a phone given to me by my dad, and first smartphone as well..
i would be very grateful for any kind of help.

After flashing step 1, did your phone restart/reboot normally?..what was asking for password? "everything goes well" for step1?
after flashing the files (pda modem etc.) the phone rebooted. but now is asking for a password go further. and when i tried to enter recovery and set it to factory settings it also asks for password before wiping the divice. tried a few times but with no success.

Greetings;
I didnt read all the stuff before...
So my answer may not be the best or accurate. (I'm almost out of time - sorry for that).
Either ways this happens to me when you don't perform a clean Flash (Formating Partitions before Flashing, wiping dalvik and cache) and after Flashing; performing a Factory Reset).
After the last step (Factory Reset) it should boot properly.
If not: Remove Battery, place it back and test if it boots.
From my experience: Downgrading ROM also do this issue. But i fix it by Flashing FULL DDLF2 (always with "clean flash") and then after my ROM Boots; Flashing the ROM i want to use.
Hope this helps.
When i flashed the first step my gt i9003 sl went completely blank except a bright light. Any solution or suggestiom
My H60-L04 was having so much trouble I factory reseted from CWM now my SD card is not detected some one please help.:crying:
How can I go back to the stock condition like out of the box condition.:crying:
To get back to stock condition, you must patient because there are quite a number of steps if you haven't already downloaded the files and prepared drivers before.
The steps:
In fast boot mode, flash stock recovery image.
Download and full stock ROM for you h6 model, uncompress it and copy dload folder to the root directory of a micro sdcard.
Insert the micro sdcard.
Apply three finger mode flash: power down phone, press and hold all vol up, vol down, and power buttons until it shows upgrading.
To flash in fast boot mode, you must prepare your PC with appropriate drivers. Fool proof installing huawei hisuite will install the necessary drivers.
You must also first download the stock recovery image and fast boot tools first and get to know the fastboot command to flash.
To boot into fast boot mode: power down, press and vol down and plug in usb cable.

Definitely you can change the defaults. Only EMUI rom works a little differently.
Here it is: Settings > Manage apps > All > Look at the bottom the left icon "Default app settings" > Click in > Change default launcher
Hey, in this tutorial I'll tell you how to unbrick hard-bricked Tab 3.
So, if you have message that you must repair your Tab 3 in Samsung Kies, and you can't recover it (you have corrupted system and have no recovery), first thing that you must do is to download Odin here: http://odindownload.com/ and TWRP recovery (make sure that you downloaded the version for your tablet): version for model P5200 - https://goo.gl/mzY5kV and for model P5210 - https://goo.gl/mcxy3E. Then download stock ROM from sammobile.com. WARNING! Never flash ROM on the tablet in such a state. When you do this, you'll see FAILED message in Odin and you won't repair anything. Then you must turn off tablet and boot into download mode (hold power+volume down+home). Then connect your tablet to the computer and open Odin with administrator rights. Now you gonna to click AP button and locate and open twrp file (with .md5 extension) and when it is loaded click Start button. When recovery is flashed, plug off the cable and then you must turn off your tablet and boot into recovery mode (hold power+volume up+home). Now you must click Wipe>Advanced Wipe and mark everything (without USB-OTG and SD Card) and click button Wipe. After wiping, you must click Reboot and Download. You'll be in download mode and make sure that there isn't any text in the upper left corner. When there isn't anything then this means that you haven't anything on your tablet. Now you must open Odin again and plug the cable in. Then click AP button and locate and open your ROM. Now you must click Start and wait. When the ROM is flashed, the tablet should restart automatically. Then unplug the cable and wait for the tablet to boot. After few minutes, you should see the welcome message. When you see it, it means that tablet is working and the repair is completed.
I hope that this tutorial helped you
this is not hard bricked this is soft bricked. hard bricked is when you cannot turn on your device to enter the recover and download mode. i hope you do your research. please correct the title.

For a difficult phone
1. Connect usb to computer but not to phone
2. Hold down all 3 keys
3. When it buzzes release power and quickly plug in usb to phone.
It might take a few times to get it right.
If it's REALLY BAD
1. Wait for the battery to completely run down and use normal method.
