Usb Vcom Driver For Mtk 8127 Processor

Sir, I have soft-bricked my tablet 7inch-micromax-P290 (1GB RAM, 8GB internal sd). I have obtained a 'P290' ROM on internet (unsubstantiated source not the official) and extracted it. There is a scatter (*.sca) file in it. But the readings in the file do not tally with the readings in the scatter file created by MTK droid tools v2.5.3, which i used to extract my present ROM before the phone soft-bricked (in my attempt to flash recovery i must have formatted some critical partition in the phone). I also used adb commands to obtain mtd partitions before it soft-bricked and have them separately from the MTK droid tools backup directory too. MTK droid tools did not create scatter file (the button was greyed out) i think this is because this tablet uses MT8127 cpu which Droid tools does not support. HOwever i used firmware.info in backup directory of droid tools to use option 'save as text file' and it created a scatter file.

Jan 29, 2018 - Usb Vcom Driver For Mtk 8127 Processor. Shutochnaya biografiya yubilyara v stihah. Sir, I have soft-bricked my tablet 7inch-micromax-P290 (1GB RAM, 8GB internal sd). I have obtained.

Lets call it 'droid tools scatter file.txt'. But the ROM i downloaded, the.sca file it has differences in start address blocks even though other parts of file are same. Ie, the lengths of blocks are same but start addresses differ.

Block size is shown as 4k in both scatter files, and file lengths are same. Now i am unable to flash the pre-loader (which i must have over-written) using SP flash tools and i also tried with wise link tool (which was included in the ROM i downloaded for P290, total ROM was 1.6GB download).

With wise link tool i get ERROR code 5054 (there does not exist the MTK_ROM_INFO structure in the ROM, does not exist MTK_BOOTLOADER_STRUCTURE in the bootloader, it is not NFB booting). Also, previously in device manager i could see Mediatek Preloader USB VCOM driver (Android) but now i see only Mediatek USB port (COM19). I tried using SP flash tool also to download pre-loader to tablet without success, it too gives errors. I would really appreciate some help at this point! I want to recover the tablet to working and install CWM or TWRP ( i prefer CWM as i used it a lot in my previous phones too and its smaller more reliable) on it. I enclose the scatter file from the ROM in.sca format, and the one i got from MTK droid when firmware.info was saved as.txt file.

There is also a screenshot of droid tools when it showed the partitions on phone (scatter file save button greyed out, ) before i bricked it a day later.
