[Android Q&A, Help & Troubleshooting] GuestX01003:
Hi,

Just a few questions. I have had a bit of experience with flashing roms (CyanogenMod, LineageOS etc) on the (Nexus S, Galaxy Nexus, Nexus 5 etc) but I haven't done it with a Motorola phone before. I am having some difficulty. It was a lot easier with those phones :) I bought a Motorola Moto C XT1758 (2018-04-17 date on box) it was bought not from any carrier or on a plan and therefore is unlocked from any carrier.

I have had trouble getting the scatter file. I set up my environment [TUTORIAL]How to setup SP_Flash_Tool_Linux (MTK/MediaTek Soc) with this guide. I am using Ubuntu 18.04.

I looked at [GUIDE][UTIL][MT65xx] Create Scatter File / Dump Full ROM For any MT65xx device, no matter how obscure

Method #1

I think that requires me to have a recovery ROM. I found that Motorola's Recovery Images are only for the Droid Maxx, Moto G, Moto X and XOOM. They also say you need a "Moto Pure Edition or a Developer Edition device."

Method #2

$ adb pull /proc/dumchar_info
adb: error: remote object '/proc/dumchar_info' does not exist

I have also read one can do:

namath:/ $ cat /proc/mtd
dev: size erasesize name

But that didn't work for me either.

I am running out of ideas.

On a side note I have tried to unlock my bootloader but have only gotten the below error. I also tried using mfastboot-v2.zip but that didn't help either.

$ sudo fastboot oem get_unlock_data
[sudo] password for me:
...
FAILED (remote: unknown command)
finished. total time: 0.002s

I made sure to go into Developer Options and toggle the "OEM unlocking", which asked for my PIN but that didn't help. I did look at Mark_Emeritus's Bootloader Unlock Problems? thread but it seems mine is in the table of unlockable CIDs, being 0x0032.

Any tips on that would be appreciated.

I haven't yet tried this [Tutorial] How to create scatter file for Mediatek devices but it looks fairly recent. I am guessing as my phone is fairly recent and has MT6735 the old method using MTK Android Devices won't work. The guide for doing this with [Tutorial] How to use Wwr_MTK + SP Flash tool to backup Mediatek rom is there. Apparently there is an alternative way [Tutorial] How to get length addresses for full ROM dump using PGPT, Wwr_MTK & SP Flash Tool.

It would be nice if there was a way to do this without Windows. Any tips or insight you can provide would be welcome.
