[Galaxy S6 Edge+ Q&A, Help & Troubleshooting] xdazywx:
Hello everyone!

So i'm startign this thread because I have been trying to fix my GM-925i Samsung Galaxy Edge 6 with no luck. The story is as follows:

1) This was my stock ROM: it is in Sammobile if you search for "telcel", sorry I didn't put the url, but the newbie restriction prevents me.

Model	SM-G925I

Model name	GALAXY S6 Edge

Country	Mexico (Telcel)

Version	Android 5.0.2

Changelist	4844656

Build date	Fri, 08 May 2015 02:32:29 +0000

Product code	TCE

PDA	G925IDVU1AOE3

CSC	G925ITCE1AOD2

2) I rooted my phone using TWRP and everything worked perfectly.

3) I installed Custom CarHDRom V.9.1 - 5.1.1 - 12/09/15 and everything worked perfectly (apart that the 5.1.1 isn´t as nice as 5.0.2)

4) I tried to install a stock ROM again (not mine, but from mexico since I read that the downgrade wasn't possible) THIS IS WHERE HELL GOT LOSE... the phone wouldn't start.

Odin got stuck in "write NAND fail"

5) I downloaded ZiDroid:

>ZEROLTE_AUS_XSA.pit (I added it in Odin's PIT tab)

and tried running them. It got about 95% of the waym but failed.

6)I tried to flash a 5.1.1 stock ROM (IUSACELL_G925IDVU2COGA_G925IIUS2COH1_G925IDVU2COGA_HOME.tar.md5) which Odin didn't let me flash because of md5 something. I removed the .md5 and this allowed me to go a little further down the Odin routin, but got stuck in hidden.img

I'm really over my head here... I think a lot of people are stuck in my situation and I haven't found any guide to solve this. I hope someone here can be the guide to solve this problem. I sure don't have the skills to do it myself.

Thank you for your help!
