[Upgrading, Modifying and Unlocking] JediMasterDroid:
I purchased a FEITENG H7100 Phone about a year ago from DH-Gate. What arrived was not a Feiteng but something else. The only difference I noticed was that instead of a QHD resolution (540x960) screen it was a FWVGA screen (854x480). I let the seller know about this difference and they reduced the price by a reasonable amount and I kept the phone.

Through some research it looks like it is a FLY 7100 phone, with the standard MTK6577 specs. What gives it away, is the configuration of the dual sims, and the sd-card slot. See:

My phone seems to be very similar to the link below:

(http://www.dealwinwin.com/Mobile-Ph...MA-3G-Dual-Camera-Free-shipping-FEIYANG-7100/)

MTK6577

1GB RAM

4GB ROM

DUAL SIM

8MP (really only 5MP) camera

.3MP front camera

It even had some perks that were better than the Feiteng.

Already rooted (that was nice)

No chinese apps or bloatware (again nice)

It of course said that it was Android 4.1, but really was only ICS (4.0). The GPS is terrible like the other MTK phones. If I run through all the GPS trouble steps (found in these forums), I can get it to lock occasionally, but when moving or turning the GPS off and on, I have to go through all those steps again. I just stopped using GPS.

There are several XDA forums that talk about upgrading the Feiteng H7100 to Android 4.1 and utilizing some of new features to improve the phone. See Here

I guess I thought because these phones are so similar and had so many of the same specs, that the ROMS would line up as well. So I downloaded VCOM DRIVERS, SP FLASH, got the new ROM, and tried to flash my phone.

I unclicked PREBOOT, and DSP_BL, as instructed and SP FLASH found my phone, but I never got past seeing the red line. I always got the famous error message.

BROM ERROR:S_DL_GET_DRAM_SETTING_FAIL(5054)

[EMI]obtain DRAM Failed!

[HINT]:Please check your load matches to your target which is to be download.

So, I thought, well this upgrade isn't meant to be. Unplugged my phone and tried to boot up. Guess what! No boot. Even though I never saw a purple line, or a yellow line, or green circles, my phone will no longer boot. It seems to be something pretty serious because, I have read about others who simply have the wrong lcd driver (FWVGA vs. QHD), and at least they got it to load and then boot. They get a white screen (led backlight) and can hear sounds, and everything but the screen seems to work. I don't even get that far. I have a black screen with no indication that anything is happening.

I of course tried Vol+ and Power-on, many, many times. In fact, I tried every combination of buttons and battery in/out. Nothing. I don't understand what happened when the SP FLASH sent a red line across my screen, but apparently that was enough to mess up my ROM image.

I can still see the phone from the computer and SP FLASH could re-load it, but I don't have a ROM to reload. After 12+ hours of searching the internet, I don't believe the ROM for my particular phone is out there. Though my Russian and Spanish are very poor at best. There are lots of 7100 ROMS (Note 2 clones) out there but none that I can see that are specifically for a FLY 7100 or similar imaged phone.

At this point, I am just looking to see if anyone knows of anything that I can try, or if this becomes a learning lesson for me.

Thanks, in advance. JediMasterDroid
