something about cm11 and cm12

Cm 12 is out of question for now. Cm 11 could be build but only from prebuild kernel because Samsung open source kernel is in mess. I have tried to build stock kernel using several method but it won't boot at all. I have made some progress with cm11 but nothing much. Still can't boot properly but it can be done. Main problem are proprietary files. Finding them take a lot of time seating in front of PC and I have not that much free time.

I don't work this for donation or earning "thanks" points. "Donate to me" is a prank. Click it and you can see. I do this because I want to improve our device so as few folks here.

But as I have mentioned before we need team of people who have some experience with android development to share their knowledge in order to make something. I open channel for core 2 and its in my signature but for a while I was only one on it so I give up.

Maybe some one need to open topic g355h cm11 Dev only where we can talk what we can do.

One man can't do anything alone but more than one can make a difference. As you can see on my github I contribute to some devices that I have never seen before. So to end this writing cose my fingers will fall of, are we going to do something or not?

BTW. Who the frack rate this topic as terrible?

Who cares :)

Sorry but i don´t fully understand... This method would fix the "not network" problem of my dual core 2 g355m? i´m don´t have a backup of the "efs" carpet but my IMEI is fine... (Sorry for my english y my "noobness"...) :)
[Samsung Galaxy Core.] Y300-0100:
U have to be more specific. What have you done to get "no network "?

Efs folder contains bt address imei sertificate, wifi mac address etc. If u have mobile data issue or network operator issue than it's something else but u need to specify what have u done!!

btw thanks for over 40000 downloads and 17 thanks hits. I didn't know that I was that good :)
[Samsung Galaxy Core.] riomah:
You´re right. Sorry for that. I bought my cel (free company) and it worked fine whit my sim card. But suddenly start to lost signal sometimes (no sms, lost calls, etc...). I thought it was because it had less space in the intern memory and i changed the rom by an original stock rom (dual core 2 g355m ARO) thinking because i do it before with my girlfriend´s cel ( Y Young Pro) would result equal (fine), but without backup and no proper investigation about the original rom (wich find out later was a TTT (trinidad and tobago free company))... Since then i had no signal. the IMEI and wifi is ok, and i tried with severals roms.... Finally call to the company center and asked to register the IMEI whit my SIM card... and nothing. Until i remembered that placing in airplane mode on and later air plane off may work and it did! But now this is the thing... Every time my cel is out of battery or need power off an then power on it had no signal until do the airplane mode thing... Any suggestions? Thanks for the patience!

TWRP 3.0.0-0 is up.

I report the 2.8.7.0 version is working on G355M variant, but 3.0.0 dont. It stuck at a blank screen.
[Samsung Galaxy Core.] Y300-0100:
it must be because of compressed kernel build for HN. In TWRP 3.0.0-0 only ramdisk is 6.5 mb. I will download sources for M and try to compile. Or if someone have sources just build kernel.

e.g.

like this: (this is for HN)

[Samsung Galaxy Core.] Dan_Jacques:
Yep. I made the root and init.d access with the 2.8.7.0 version, and all worked flawlessly.

The only thing I miss for this phone is a custom kernel with more options. The stock hotplug is slow, I miss Zram and UKSM. That could improve the battery juice and performance (the phone has low memory).

[Samsung Galaxy Core.] Y300-0100:
You flashed twrp 3.0.0-0 g355h and after reboot to recovery you got white screen?

Don't have idea why. I just would like to know is there more owneres of 355h that can confirm does it work or not. Because there are a lot of downloads but no comments.

ps.

For those who don't have pc to flash new recovery if they stuck in white screen must have installed android terminal.

https://play.google.com/store/apps/details?id=jackpal.androidterm

To back up current recovery type in terminal next:

su

dd if=/dev/block/mmcblk0p18 of=/sdcard/recovery.img

and check is your recovery on your internal storage. To flash it back type next:

dd if=/sdcard/recovery.img of=/dev/block/mmcblk0p18

No reboot required.

Hi Guys,

I'm currently in the process of building AOSP to just flash a basic image onto a Nexus 7.

I've done the "repo sync" to get all the relative files, and have initialized the build environment exactly as the tutorials on the Android development site asks, including downloading proprietary drivers, however whenever i'm trying to do my first "make", it either gives me an error saying a random make file received a kill signal, or my machine just freezes.

As of writing this a build has been going for 7 hours (Is this normal?) and the machine just freezes up.

Any help/advice would be greatly appreciated, i'm unsure of how to try and fix what's happening

Hi, I flashed my Nokia X with wrong zip from recovery. I think the phone is dead, when I connect the device to my linux pc, it's detected as partitions, there are many files in there of recovery, system,... and even my internal storage is detected (on windows nothing is detected). So when I plug the device in to my USB, the phone juste vibrates then nothing appear. Same thing when I remove battery then click power button. I hope anyone here can help me!

[Upgrading, Modifying and Unlocking] syncopath:
My Wallaby (with Windows PPC 2002) is too central to my life for me to risk losing it by daring to flash it with a new ROM. This means that new tools, ringtones and things have to go into its mere 32 MB of RAM. On the other hand, this RAM is also cluttered up with "skins", sounds and things (including a version of Windows Media Player that has always resolutely refused to work) that Microsoft, HTC et al. have decided I must have. Mostly if I try to delete them, either using its native File Explorer, or via the cradle with Explorer from my computer (Windows XP Pro SP2, local adminstrator account on the PC), I get an error message, "File in use or write protected", that sort of thing, i.e. I'm not allowed to delete them.

Can anyone help me with the following?

- An explorer tool which will let me see and change attributes and permissions where necessary, and delete unwanted files from RAM?

- Any information on possible Windows PPC 2002 equivalents of accounts, local, administrator, etc.? My unsuccesful attempts to delete files have a distinctly "not local administrator" feel.

Another thing that would be marvellous, would be the option to use the (currently 128 MB) SD card as a sort of hard drive, i.e. to put large executables on to that and start them with something like a shortcut, so that they only load into RAM when they're actually needed. Can anyone tell me any more about whether this is possible, and if so how?

Thanks to all in advance.
[Upgrading, Modifying and Unlocking] Rudegar:
you cant delete files in rom of the device and even if you could it would not add more program memory or storage on wallay you can only access the rom at flashtime

and at all other times it's readonly and dont take up any of the ram of your device

Thanks for your reply, Rudegar, but I'm looking to delete things from RAM, for instance \\device\program files\windows media player\*.* Am I wrong to think all this stuff loaded from ROM into RAM after the last cold reset?
[Upgrading, Modifying and Unlocking] syncopath:
Oops, I just discovered I can delete the files mentioned above (and did), from the native File Explorer. However, when I tap and hold \\device\windows\player (the media player executable, presumably player.exe) the "delete" option is greyed out in the context menu.
