Hi there guys.
I need help with my wife mtk6735 phone (Tecno C8) which was throw inside water by my kids and refuse to power on, no button works, not charging, went dead. she took it to three different engineer for repair they said no remedy after trying there best... now d phone does not charge but when it does it 0% and when power on its stock on experience SMART with unclear screen of different color then go off and not charging again (i guess one of the engineer flash the wrong preloader)... so i put it on meta mode myself for flashing, detected is mtk usb
I need help flashing it with SP Flash Tool which gives an error as described in title. i don't know d variant for d box has been thrown away?. i have downloaded, use different stock rom for tecno C8 on internet e.g.
1. C8-H353-A2-L1 variant1.
2. C8-H353-A2-L-20151207 Var2.
5. Tecno C8-A2 .
yet it wont flash, i have d same error.. i have watch videos regarding d error code, i have install all necessary software required for flashing, uninstall with deview, install again, i choose download option, with or without batery, format all and download, upgrade firmware, format without boot loader, change preloader from d same mtk 6735 to flash, use different usb cord yet it wont work..i have the same error...
After i press the download button, and connect my phone, the bar at the bottom goes to 100%(red colour) then stays like that for 21-41 seconds.
Then it gives the error code and fails to flash.
I tried everything, from removing the battery, pressing vol+, vol-, power and all the combos in between, nothing.
If someone could help me unbrick my wife phone, i would be very greatful.
P.S I need the stock ROM backed up from my wife device Tecno C8.... i can attach the picture the phone
