1) How it got bricked?
I have a JIAYU G3S phone, MTK 6589 (Without T). Comes with 4 GB Internal storage, 1 GB RAM. One day it started freezing whenever I enable Wifi, after number of hard restarts, it stopped responding, battery probably drained and stopped charging, and turning off.
I connected it to the PC, trying to see if it can be recognized. It was identified as MT65XX device, and kept disconnecting and connecting all the time. While I didn't have enough information on what that means, I decided to Flash it again.
I downloaded the Original ROM from needrom.com, using the same SP-Flash tools, it gave some error, that I can't remember what was it. But since then I'm trying to download different SP-flash tools and ROMS and nothing is helping. Things were getting worse, I think that I once formatted everything including address zero, NVROM, and things are just getting worse all the time.
2) What versions I'm using?
I tried many SP-Flash versions, and I tried also Multi-SP, tried with versions of 3.XX, and tried of versions of 5.XX, both give different errors.
3) Current status?
I have two PCs that I'm testing with them. One is Windows 7, here the phone is identified as DA VCOM USB. And using XP, it's identified differently everytime, once as DA VCOM, and once as MTK USB Port. I tried "Download" using latest version of 3.XX series. Sometimes it gives me no PMT, somes tells me S_DA_SDMMC_WRITE_FAILED, sometimes S_DA_SDMMC_READ_FAILED, never passing the red progress while downloading or even format all + Download. I tried to pick ONLY preloader with MBR, EBR1, EBR2 and UBOOT, I tried to pick ONLY preloader. I tried to pick only recovery, then it tells me something about enough space in SDMMC (although according to my scatter file I have EMMC, not SDMMC).
I already spent more than 30 hours reading forums everywhere, and trying to see similar problems, to see how can I try to push SP-Flash beyond the red progress bar. Nothing helps.
I was able to ONLY get it to full "Format" using latest SP-Flash. I put battery (USB unplugged), I plug USB, I remove battery, I hit Volume Down, then it formats full, with green circle.
Since I'm able to format, I don't think there is any problem in the USB cable or the installation of the drivers. I'm able to do that on both PCs.
4) I have an other exact model Jiayu G3S in working mode. I tried to do MTK-Droid tools, backup everything, and created a package for flashing, and I'm getting same errors also with the this ROM that I prepared. So having a similar model is not helping as well.
Sending the phone to China to get it fixed will take more than 90 days to get back to me, and I'm spending alot of time trying to fix it without any help.
A) Based on all material presented above, do you think that it can still be fixed?
B) If the PC still recognizes the phone, does it mean that it can still be fixed?
C) If the phone is able to format, does this mean that the Hardware is okay or there still might be hardware problem that is causing the flashing problems?
I would appreciate every effort to resurrect the phone. I'm totally exhausted reading every little bricking post / thread / reply, to find a solution to my phone.
