Had the exact same problem... Worked perfectly, and I had no faith in it working. Very useful to read this post.
I'm going to summarize my experience:
1. Repartition with PIT file (take out battery, put it back in, and again to downloading mode with combination buttons)
2. Flash XXKPE
3. Then flash the gingerbread firmware you desire. DONE !!!!

Hi Guys,
I tried to flash my Stock Firmware (JPJV6 ) recovery 3e , Gingerbread 2.3.3 in GT-i9000 using odin 3 v 3.07 . I downloaded 'one file' firmware for my device from samsung-updates website.

Now it stopped in recovery mode with this E:failed to mount /dbdata....& E: rfs format failed on /dev/block/stl10
So when i reboot the device it everytime goes to Samsumg S Logo and reboots again (BOOTLOOP).
Please provide me solution to get back my stock firmware.

Maybe I wrote it wrong again... I CAN get into Download Mode and Recovery Mode... I also tried to flash a Stock-ROM and then restore the backup... but the phone cant start after I flashed the Stock-ROM or after restoring the backup...
Maybe my way is wrong...
I do it like that:
1.Start Odin
2.Open PDA and choose the XXLE4 Stock ROM
3.Start
4.After this was done I try to restart...
I think there must be a wrong step...

I tried it... I flashed Latona pit with those settings, and then, after I removed Battery one time, I flashed the Stock ROM, but there was a boot loop again.
After there was a boot loop, I also tried to flash CWM and then restore the backup, but at the end I saw again:
Restoring datadata...
Error mounting /datadata!
Skipping format...
Can't mount /datadata!

[Completed] SPH-L710 soft bricked help.

I am running philz 6.41. I updated to nj3 on my sph-l710. Every time it boots it shows a error that the system file is corrupted.
I did encrypted the system along with the SD card. it says to do a factory reset but does not help. I did the same with my wife phone but her phone is working fine. Pleas help how can I get my phone back. If i try to flash any roms I get please update binary in philz.. I have tried to flash the stock rom and use kies factory recovery.

Hi,
Here is a guide on flashing stock. If you have any questions you can ask there too...

Also, Kies must not be running for Odin to work properly. Check in your PC's task manager and kill any kies processes that are running before starting Odin.
Good luck!

Help with bootloop issues after CLEAN flash odin SM-G9200

Hello, i have the SM-G9200ZH (Hong Kong version)
I disabled some system apps through pdp and got into a bootloop, after trying many things i did a factory reset and flashed through odin this firmware which is the latest
G9200ZHU2ERK2_G9200ZZH2ERK2_G9200ZHU2ERK2_HOME.tar the phone showed the bootanimation and then restarted to itself to bootlogo, over and over again.
So then i found a Pit file, and correct AP, BL, CSC, CP files for my device G9200ZHU2EQL1_G9200ZZH2EQL1_7.0, i flashed through odin selecting Nand Reset and Re-partition too.
At this point i still have the same issue, Phone goes into the bootanimation and then restarts itself over and over again.
The only way i have made the phone boot is by installing a custom ROM with TWRP, but i cant use any because it doesnt recognize the sim while using them.
Every time i flashed a firmware, When first booting i got a blue screen on the stock recovery that goes to 32% and then fails and says erasing.
Also im not using my Original Cable
So, can someone help me to make it work again? or to Tell me which custom rom actually works for my phone.

Did you try "wide /data" right after you've flashed the stock ROM?

I did wipe data right after flashing through Odin, and also tried not wiping data after flashing through Odin. None of these worked, I don't know what to do

You can try flash twrp through odin then magisk/ supersu through twrp

When flashing stock rom with Odin, rebooting is stuck at boot logo

Hello, some days ago i found a Samsung Galaxy Ace Style (SM-G310HN/heatnfc3g) and i decided to mod it, i installed TWRP via Odin and all was ok, but when i tried to install CyanogenMod 12.1 it didn't work. Since it didn't work, i decided to flash stock ROM. It worked once, but now it doesn't work anymore. I suspect it's the PIT file, because when i reflashed stock ROM another time with a PIT file now it doesn't work anymore, let me try to explain:
When i try to flash anything (Stock ROM or recovery, custom or stock), it... doesn't, Odin says it flashed but when i reboot to recovery or reboot to stock, it stays at the Samsung logo or doesn't flash the recovery, even if it says that it flashed. What should i do? Is my phone bricked? How can i unbrick it if it's bricked?

Have you tried booting into stock recovery and selecting the factory reset option and the wipe cache partition option? It is sometimes necessary after flashing via Odin, I've had to do it a few times to solve a bootloop.

Well the problem is... i cant reboot into stock recovery. Its stuck in twrp, and it's not really a "bootloop", it stays stuck at the Samsung logo. I tried to wipe cache and dalvik on Twrp but nothing.
I cant even flash the stock recovery since as i said in the original post, if i try to flash EVERYTHING Odin says it flashed but on the phone nothing happened.
