Kernel source / flashing custom kernel / swap

Hello all. Does somebody know where to get the A789 kernel sources? The 512 MB of RAM begin to be too short, and I would like to use a swap file on my external sd card... Unfortunately, it seems that the stock kernel does not support swap. So I would like to recompile it with this option enabled. Thanks.

Edit:

I know that it is not the right place to deal with development topic, but I am not authorized to post on the other thread (Lenovo A789 factory&custom ROM (ICS). Sorry.
[Android Q&A, Help & Troubleshooting] cybermaus:
Swap space? Can you tell me why you think the kernel does not support it?

The way I understand the Android OS (or at least, the way others explained it to me) is that Android is moving active applications to and from main memory on its own method. Kernel swap mechanism may not be helpful to that Android mechanism.

In fact, if you trick the Android into thinking it has more memory, I think that what may happen is that Android may at some point decide to move the least used app from 'memory' to disk, which in reality means it is moved from swap to disk. A very useless move, I suspect.

But you are welcome to try. In fact, if I have some time left, I shall also play with it. Some tips: rather than a swap partition, you could try a swap file. Also, rather than on the external SD card, why not use the internal one, I think the internal eMMC is much faster than the external SD. And maybe you should check to see if the 'swapon' command is not in the busybox that you can download from the Play Store.

I suspect swap is part of the kernel, never seen a kernel that did not have that, and all you are missing is the swapon command.
[Android Q&A, Help & Troubleshooting] lolo250612:
I agree with you that a swap partition or file is not the most efficient way to add ram to a system. But have no other choice. Android indicates just that memory becomes low on my phone, and that does affect the stablility of a few apps. This happens especially after launching some heavy apps, like Chrome which is a quite big ram eater.

According to some other xda threads, other people have greatly increased the overall stability and responsiveness of their phones by adding a swap. One additional drawback is a shortened sd lifetime but I am willing to take the risk, given the fact that a SD is quite cheap nowaday, even a class 10 (and that the reason why I also prefer to select the external sd card).

What I have is as following, from a console (swapon is present on the system with busybox installed)

dd if=/dev/zero of=/mnt/sdcard2/swapfile bs=1024 count=655360 -> works

mkswap /mnt/sdcard2/swapfile -> works

swapon /mnt/sdcard2/swapfile -> swapon tells "Function not implemented"

Also, some tools, that automate the task, like swapper2 or swapper for root, fail also.

So I guess that it is because the kernel was compiled without swap support. But maybe am I wrong?
[Android Q&A, Help & Troubleshooting] cybermaus:
I think you are correct. And I also think finding the kernel source for the MT6577 / A789 is going to be hard, if not impossible. Sorry bro

I have found this video of SP Tools very informative, would or could some kind soul follow the video and extract the full lenovo a660 rom for me. I have solved the error with SP Tool not being able to write to the phone but inadvertently i can not boot the phone or get response from it except to write with whole rom again with SP Tools (ie a TFT). if some one could extract the rom as in the way the video shows i`m quite positive i should be able to write the whole rom again and be back up and running

Thanks to anyone that can help

I'm really sick with lenovo phone, but i'm sorry its not about (A750, A789, P700i, A660) .

My Lenovo A800 bricked because I was accidentally flashing the phone using SP Flash Tools with incomplete MTK Root & Tools backup files.

After some search, I found factory rom А800_ROW_S107, then I flash using SP Flash Tool.

Its make my phone wake, but the IMEI & WLAN Mac address and probably some identity that stored on NVRAM are changed.

Found temporary fix for imei by changing them using MTK Root & Tools, but every wipe data & cache, imei are become dissapear again.

I'm currently thinking to swap NVRAM data from the factory rom А800_ROW_S107 with NVRAM data from MTK Root & Tools backup files then flashing with SP Flash Tools.

but the problem is userdata.img is un-packable, I was tried with simg2img but no success, when i tried mount the result file, its only show blank 640 MB File system.

is there alternative ways to unpack & repack userdata.img? so I can get my original NVRAM data permanently.

or other ways to restore my backed up MTK Root & Tools NVRAM to the new rom permanently.

thanks before..

btw its my 2 days Lenovo Phone :silly:

WiFi Stuck at Turning on..

Hello everyone,

Ive had my P700i for about 4 months now and has been rooted since. However, just a few days ago my wifi just decided to stop working and get stucked at "turning on WLAN.." whenever i toggle the slider switch in the settings menu. Im pretty sure this is not a hardware issue as the phone never got hit, wet, fell off or anything alike.

I have tried to do a factory reset, wiped everything clean, flashed all of the available roms (thank you cybermaus by the way, ur roms are pretty good and clean) and even the original S105 firmware, bricked and unbricked my phone two or three times already, all of the possible combos of desperately looking for a fix.

I really need the wifi of the phone as i find viber essential to my work.

Anyone experienced the same issue and found a fix for it? Please please please share..
