I just tried to flash patched boot image (gotten from Magisk apk) but the error SP Flash Tool is saying "chipset mismatch: scatter 6755, device: 6750"
So I tried renaming the scatter.txt from MT67T55 to MT6750 but got the same error mismatch again
As for booting into recovery, I tried that but it got stucked at the android logo, nothing else was showing despite pressing the power button severally as well as the volume keys
What do I do?

(21-06-2018, 03:06 PM)innagee the full ROM is valid but you'll have to repeat the process to obtain valid scatter file else SP flash isn't going to flash the firmware obtained.I'm getting chipset mismatch from SPFT chipset mismatch scatter: MT6755, device: MT6750
How do I get MT6750 scatter text for the device considering the procedure I chose was MT6750 but it created MT6755 scatter.txt automatically with the ROM dump itself?

create scatter file for your chip type from the beginning of the tutorial, see point no. 3 on page 1.

5242880 trustzone2.binAfter flashing TWRP successfully I tried to adb sideload a ROM.
The rom appeared to send to the phone successfully, and the console output in TWRP reported no errors.
I tried this with lineage-14.1-20171223_034051-UNOFFICIAL-namath and DOT-N-v1.2-20180130-namath-OFFICIAL after rebooting both ROMs showed their boot logo and just stayed like that forever. Every now and again the clock in the top corner would appear along with a picture of a battery and simcard with a cross through it.
I suspect this is because I didn't restore my modem firmware. However as I did the above guide I want to extract that file from
Code:
/system/vendor/firmware/modem modem_1_lwg_n.imgI found this guide that uses unyaffs however when attempting that I was seeing:
Code:
Can't determine flash layout, perhaps not a yaffs2 image This post was last modified: 01-07-2018, 08:00 AM by tya.
