Kernels info:
dreamer7 kernel build with a few advanced features:
- VM Dirty ratio tweaks
- Added frandom driver
- Faster NOATIME and NODIRATIME mounting flags
- Asynchronous I/O latency to a solid-state disk greatly increased
- Compile vfp with neon
- Random: Entropy tweaks
- CPU governor added – ZZMOOVE (Default)
- New IO Schedulers added – ROW, ZEN, SIO (Default SIO – 1024)
- Intelli_plug driver (by @faux123) – An interesting thing which is now engaged in enabling and disabling cores (support profiles and some settings), also allows you to set the frequency in offscreen mode (754 instead of 1209 exhibited in the standard)
- Optimized ARM RWSEM algorithm(by @faux123)
- added multi core saving mode
- Sweep2Wake, Sweep2Sleep – disabled at the kernel level
- LZ4
- F2FS support (yet in fact, it is necessary to build the kernel for recovery to install the system on this FS)
- O3 optimization when assembling + other optimizations
- support for workqueue power-efficient mode
- implement LoUIS API for cache maintenance ops
- update cpu_suspend code to use cache LoUIS operations
- shorten freezer sleep time using exponential backoff
- wireless: Increase scan entry expiration to fit new scan time
- flush L1 cache in cpu_die
- Bluetooth: Fix SSP acceptor just-works confirmation without MITM
- Bluetooth: fix possible info leak in bt_sock_recvmsg()
- various fixes in processing workqueue
- ALSA: pcm: fix fifo_size frame calculation
- fixes in the TCP subsystem
- new cpu governors: [pegasusq], intelliactive, sakuractive, nightmare, interactivex, lulzactiveq, smartassV2
- slightly corrected the intelliplug settings
and a lot of other patches …

Increasing the System partition to 1.0 Gb with simultaneous increase of the Data partition.
Suitable for those who have the native phone memory partition.

Available options:
System1Gb-DataStock.zip —- increases the /system partition up to 1GB, /data partition to 1.5GB.
System1Gb-Data2.5Gb.zip —- increases the /system partition up to 1GB, /data partition up to 2.5GB.
System1Gb-Data5.0Gb.zip —- increases the /system partition up to 1GB, /data partition up to 5GB.
System1Gb-Data10.0Gb.zip – increases the /system partition up to 1GB, /data partition up to 10GB.

Important:
1. There will be formatted partitions System, Cache, Data and Emmc (internal SD) – save data if necessary! All data in internal Sd will be destroyed!
2. If you want to return the native partitions the install through recoveri SystemStock-DataStock.zip (by analogy with System1Gb-DataStock.zip)

Attention!
Be careful when performing the instructions! Thoughtfully read and not to deviate from the above course of action. Pay particular attention to the strict implementation of the right step 3. For any wrong-doing will be a brick!

Instructions:
First, make a backup of the existing firmware and/or copy to an external SD card file with the new firmware, which will be installed after repartition. After performing the following steps will have a mobile repartition phone WITHOUT SYSTEM, it is necessary to reinstall or restore from backup!

1. Take the patch from the folder "Patches for Recovery", for example, System 1Gb-DataStock.zip, copy it to the SDcard (extSDcard – a removable SD flash drive and nothing else!).
2. Install it through Recovery (I recommend CWM 6.0.4.4).
3. Reboot again in recoveri and format partitions System, Cache, Data.
4. Connect your phone to your PC, go to the Recovery section mount, and mount intSDcard – internal memory as a USB-drive to your PC.
And with the PC format the intSDcard – internal memory in fat32 (cluster size you can leave the standard).
5. Repartition passed.
Restoring from a backup you firmware or install the new.

Attention!!!
1. Do not repartition the memory in other ways, before return to the native Memory partition – get a brick.
2. Whatever you do – do at your own risk.
3. The archives with patches has detailed instructions on rusiian language.

TWRP 2.8.0.0 – is recomended

Attention!!! All data on internal SD will be lost!!!
This patches are installed only on the native memory partition!
Recomended recovery – TWRP 2.8.0.0 = for С2/980, C3 = = for C7/990 =
Repartition files for 16/32Gb phone version:
System-1Gb Data-Stock – System partition is 1Gb, Data partition is default.
System-1Gb Data-2,5Gb – System partition is 1Gb, Data partition is 2,5Gb.
System-1Gb Data-5Gb – System partition is 1Gb, Data partition is 5Gb. (Recomended)

Repartition files for 4Gb phone version:
C2-4Gb System-1Gb – System partition is 1Gb, Data partition is default.
C2-4Gb System-Stock – Default partition set.

Instruction:
    1. Copy rom into your external sdcard.
    2. Copy zip file with the partition type into your external sdcard (for 32Gb version recomended System1Gb-Data5.0Gb, for 4Gb version – ONLY C2_ROM-4GB_System_1.0gb).
    3. Wipe -> advanced: dalvik cache, cache, data, android secure, system.
    4. Reboot -> Recovery.
    5. Install zip file with the partition type.
    6. Reboot -> Recovery.
    7. Wipe -> advanced: dalvik cache, cache, data, emmc, android secure, system.
    8. Reboot -> Recovery.
    9. Install rom with needed options.
  10. Reboot -> System.

If you have an error: error executing updater binary in zip when installing these patches, it means you already made the repartition other method.
In order to apply these patches, should be return to the native partition.
You can do this by using SPFlashTool3 by installing the stock firmware use button Firmware Upgrade.
