Here is the video tutorial on how to unbrick every mtk based chinaphone



You need this after you have flashed a wrong preloader and your phone shows up as "MTK USB VCOM PORT".


Here is also a good article on XDA:

I´m using a HDC Galaxy S5 in this video. A review can be found on my channel

just so that you all understand about why you get error's sometimes when you flash roms for mtk devices it is pretty simple...these roms are usually not built from scratch like most roms you find on XDA for samsungs and other devices,they are usually "ported" this means that somebody put it together using different parts from other roms added some shit...got rid of some shit and called it a rom...a good percentage of them work quite well and sometimes they do not...i was lucky enough to get one made for me by one of our users...ufo8mymunky...and she did a great job...she made two roms..one was fantastic debloated of loads of crap and works like a dream...the other didn't work well at all and kept crashing..so we must accept the good with the bad


then we have the devices themselves...like over at oppo forums where some people flash a rom and it works fine and others flash the rom and have multiple problems...phones are like cars...some are good and will go for years with no problems...and as you can guess some will have problems within weeks of driving them out of the showroom


then last but not least we have the worst culprit...user error where people swear blind that they are doing everything correctly but they unfortunately have fucked up somewhere and do not realise that they have done it...this happens quite a lot with people who have not done this type of thing before and are not used to the system and how it works...the best way to avoid mistakes is to do things slowly...and read the tutorial over and over just to be sure you understand every part of the process then when you are ready you can continue on and attempt to flash/backup or install


hope this clears things up a little for those of you who keep encountering problems whilst trying to do the above

Hi Guys,


I've just bricked my new CUBOT S308 with a wrong version of KK rom.:dizzy:


My current phone is completly dead; if I connect to PC with USB I could see only MTK USB VCOM PORT.


Just tried to apply the procedure shown into the VIDEO using SP Flash v 3.13 but unfortunately my phone doesn't  start the download and PC return a popup message of error (DRAM).


Anyone may help me?:whistling:

Hi,


I've got different errors, but I tried with different ROMs:


- KK 4.4.2 V0.009


- KK 4.4.2 V0.004


-JB 4.2.2 V004


-JB 4.2.2 V003


These night I'll try again and I will be able to provide exact error codes.


thank you
