[ROM][InDev] Help Wanted Custom ROM Option for SGH-I857
- Thread starter Legojr
- Start date
Using 7-zip for extracting the tar.md5 firmware and MagicIso for extracting the system.rfs file.
I assume you got the firmware from a site like Sammobile. I think I have a similar tar.md5 we have to find away to flash it if we want to flash anything in the future.

There is our problem, this phone has a firmware problem i guess, cause it doesn't flash anything, I've noticed this already.
There is a way to flash to it. I soft bricked my DoubleTime once and I played dumb to the AT&T store and they flash stock firmware to it.
If I had to make an assumption, I would say they used Odin. I'm just not sure which version, or if they even used the same firmware image as us.

There is not other way to flash the device, Just kies. This means there is a possibility to flash it! Could you make a research to know which tool they used to flash it?
I actually can't even get Kies to work unfortunately. I could just walk up and ask them, but I'd doubt they'd tell me. We could also try Hiemdall;it might even be easier.

I haven't tried it, even seen it. I've always used odin to flash, restore and make money
but we don't have anything to lose. And you don't lose anything asking them :laugh:

First off I'd like to apologize for the time this has been taking but I've taken apart my hard-bricked DoubleTime and I've compiled a list of all of the parts inside:
CPU: Qual MSM7227
Cellular Radio/GPS: Qualcomm RTR6285
Wi-Fi: Atheros 6003G-AC2B
Power Management IC: Samsung MAX8899G
Audio: Audience A1026A0F
Bluetooth: Broadcom BCM2070
Charging IC: Samsung 9280a
eMMC: Samsung KAT007012C
This is different than what some sites have said were inside but this is good because this means the DT is similar to the Samsung Galaxy Ace, so we can look at that code to help build a recovery and we can make a Froyo ROM using some copy-paste magic.

Can you create a flashable zip file for flashing via stock recovery, i mean a recovery which just opens flashing it everytime you need it, there some like this.2
I'm not a great here just like the contributors or reconigzed, but I can do something, do you need help?1Well no better way to learn than hands on and on your own... Good luck! I have one of these worthless phones laying around to give to my youngest girl 6. It's just sucks it's stick on Froyo 2.2

I have this phone and would like a little of hacking on it. Have you gotten anything?1I've heard about that but I'm not sure if a stock recovery can flash a recovery on itself.
Besides a recovery.img that we know will work is needed for that and well... we don't really have one.
Being a noob I'm not sure how much is testable before flashing but I believe that those binary files are going to be needed. Do we just need the vendor-blobs.mk file to copy everything in system/lib, system/bin and system/etc directories?
Search for guide for creating the flashable zip, this is the better way to get a fast recovery working in any device, about the vendor-blobs.mk, i have not tried to create a recovery, so i can't help.
