Nokia 7 Plus has following size of both partitions:
system_a/b: 3,221,225,472 bytes
vendor_a/b: 1,073,741,824 bytes
Nokia 6.1 Plus X6 has following size of both partitions:
system_a/b: 2,684,354,560 bytes
vendor_a/b: 536,870,912 bytes
Differs of these partition size: 2,147,483,648 bytes, or 2 GB.
This will give you more space for putting your own userdata especially when you're using 4+32 variant Nokia X6.
So what's the point of partition enlargement?
This will allow you flash the same heavily customized ROM like MIUI10 for GSI_SDM660_64 devices.
WARNING: Repartitioning will destroy your userdata, always do backup before proceed!
1. Enter your phone to Download / Fastboot mode.
2. Extract and flash the gpt_both0.bin attached in this topic:
fastboot flash partition B2N-0-339B-gpt_both0.bin
OK, now you've finished repartitioning. You'll need to reinstall DRG-345B-0-00WW-B03 or DRG-347C-0-00CN-B04 full OTA update zip. You can't use stock firmware from https://fih-firmware.hikaricalyx.com/hmd_en.html#drg , otherwise it will revert your partition table back to stock.
To reinstall the payload.bin as fastboot images, please follow this guide:
For you convenience:
DRG-354H-0-00WW-B03-update.zip can be downloaded from: https://android.googleapis.com/packa...fdeba776ef.zip
DRG-347C-0-00CN-B04-update.zip can be downloaded from: https://ota-filesite.c2dms.com/SWImage/500002275
You must erase userdata otherwise the phone will refuse to boot.
I don't know if this operation will break OTA update, but since the major point is using custom ROM, who cares?
