Only crashes when copy the .36...what would be the problem of the second capture?
[MeMO Pad 7 General] Ruben Craveiro:
Is most likelly because of the ram, nothing we can do about it, will happend in all roms.. in 36 lite it happends less, but still does and stock it happends alot
[MeMO Pad 7 General] jerbear294:
It's definitely because of the RAM.

If you change RAM settings in Kernel Adiutor, programs will actually stay in memory but the tablet will be much more unstable. I found that out the hard way :p

Hi there,

I'm a newbie and I'm trying to make a ROM for my K013....with this tutorial:

http://xdaforums.com/chef-central/android/guide-android-rom-development-t2814763

Now I had installed Ubuntu 15.10 and had already download the 10GB CM11.0

but I need the[ Device Tree] and [Vendor]

where I could find [ Device Tree] and [Vendor]?

or where I could find the tutorial about how to figure out these ?
[MeMO Pad 7 General] jerbear294:
That's the problem :P

With devices that haven't been ported yet, you have to MAKE the device tree.

I'd suggest waiting until [MENTION=4821597]social-design-concepts[/MENTION] releases his common Baytrail device tree "framework" before experimenting.
[MeMO Pad 7 General] Ruben Craveiro:
honestly if your a newbie, dont try to make it, just my opinion, do it if you want but, social design concepts is already making one so i dont see whats the point of making another one.
[MeMO Pad 7 General] LuctenFinger:
yeah, I just want to DIY, to learn about how to build a ROM :)

you know, it's exciting to build my own ROM from source code

---------- Post added at 01:09 PM ---------- Previous post was at 12:50 PM ----------

oh, that's pity:(

but I don t want to just wait and doing nothing at all:mad:
[MeMO Pad 7 General] Ruben Craveiro:
theres something you could do... go a few posts back download the twrp backup of kitkat system image, and download the boot.img of .33 and .182 and try to make the boot.img of .182 boot with the system image of kitkat.
[MeMO Pad 7 General] Mis012:
You can compile stock kernel from source code :)

P.S I again want to ask if someone knows what gnu/linux distro and what iso was successfully booted on this tablet (including X working) It seems baytrail support is not as good as it could.

Also building gnu/linux from source might be needed to get wifi working, so another thing to compile :)
[MeMO Pad 7 General] LuctenFinger:
ok,I'll try
[MeMO Pad 7 General] rodrengo:
I was finally able to flash the official .36 (I could do so only via file manager in TWRP, because root explorer was restarted and gave me this error), then installed the Russian .36 and achieved do working the camera and bluetooth in the lite .36.

What is the difference between the official rom .36, and repacked? I thought the official was losing TWRP, but still works

Thanks to all for the help
[MeMO Pad 7 General] thegreatn_:
Repacked flashes via TWRP
[MeMO Pad 7 General] tim_h:
You are probably right. But there is always hope. ;)

By the way, have a look at the attached screenshot. After charging to 100% the tablet just sat there idling, with WiFi off. For an hour or so battery drain was minimal. Then, suddenly, without user interaction, the battery started draining very quickly. After a reboot battery drain went back to minimal.

Any idea what is going wrong there? Is there a tool with which one could try to find out exactly what causes the heavy battery drain?

Glad this worked out!

I just download the .17 Kernel code from Asus official and have a glance

the .17 Kernel use Linux Kernel 3.10.20

but the KitKat .161 Kernel is strange............................why its so BIG of 1 GB ?

I have just unpack the WW.182 and WW.17 boot.img , use the 'unpackbootimg' in CM11

when I upack CN.182 boot.img ,is says:

'android boot magic not found in boot.img'

it sounds like the IMG header is broken?
[MeMO Pad 7 General] :
Flash SuperSU from TWRP
[MeMO Pad 7 General] Ruben Craveiro:
First of all, the IMG header isn't broken, what is happening is that the tool your using is looking for the Header "ANDROID!" which 182 doesnt have because 182 starts with &OS&, so ill put the link of boot.img of 182 and 33 with ANDROID! header

and a link for unpacking tool called Andimgtool that social design concepts gave because for some reason even with ANDROID header your tool wont work.

Links:

https://mega.nz/#!JBdHzICB <-- Boot.img 33 + 182

https://www.androidfilehost.com/?fid=95864024717073970 <-- Andimgtool (use it on pc, and open cmd, and cd into the same folder as the file. and open the file to see the commands so you use them on cmd)
[MeMO Pad 7 General] LuctenFinger:
needs key to download that......

https://mega.nz/#!JBdHzICB

P.S. I use linux so I cant run the .exe file
[MeMO Pad 7 General] Ruben Craveiro:
not much i can do about that then..

but anyway heres the link..

https://mega.nz/#!JBdHzICB!TETcgtQ6oK5Ef3iUnr3xh7QrL1CCdkezSns5Fm4rXRU

now it should be avaible

you could maybe dualboot or use virtualbox
[MeMO Pad 7 General] jerbear294:
Except you can. You can install WINE, it's a program that runs Windows EXE files, natively.

It's hit and miss sometimes, but it keeps getting better and better.
[MeMO Pad 7 General] LuctenFinger:
its not matter , I read the 'unpackbootimg.c' source code and xxd the boot.img on .182

I just find the unpackbootimg working method:

1. read the header and find the address of other parts in header

2.read other parts

but .182 boot.img is different---------

it simply has NO header !

because the address of other parts is fixed !
[MeMO Pad 7 General] Mis012:
With lollipop they started to compress it, if you unpack it gets bigger :)
[MeMO Pad 7 General] Ruben Craveiro:
.182 has a header.. its &OS&, use a hex editor to see it..
[MeMO Pad 7 General] Mis012:
That is magic signature. By header he means plain text with info like cmdline and offsets of kernel and initrd
[MeMO Pad 7 General] LuctenFinger:
I finally find a way to unpack the .182 boot.img ,

but by now its too late in china , I feel tire and cold ~~

I 'll post it tomorrow

P.S. the 'xxd' is a hex editor....

actually , I dont know wether it has header or not , its just some symbol that human cant understand .

I mean , its not important ,

but the address of parts is fixed , so we can extract them directly :)

cannot upgrade from .24 to .36 (stock) and then to .36 (leightweight)

I follow this thread from the very beginning and I was always hoping for a custom rom to be published any week or so. But nonetheless I cannot stand the constant restarts and issues I face on my .24 (I came there all the way from kk by normal OTA).

Now I read so much about the russian .36 (leightweight) that I prefer this over my .24 but still waiting for CM.

BUT as I understood I shall not upgrade directly to .36 (leightweight) but upgrade to .36 (stock) before not to risk having trouble with the cam and bt.

Unfortunately I didnt freeze all the ASUS crap but I deleted it when I installed .24, therefore I cannot upgrade to .33 or .36 the OTA way. (It is rooted, obviously)

Even having read the whole thread so far I must admit that I usualy have no clue what you proffessionals are talking about. And I totally forgot (it must be somewhere in this thread) how I can upgrade even if my tab doesnt let me do it the OTA way.

Therefore please excuse me asking this very noob question: how can I upgrade the normal/OTA-way from .24 to .36 since my system isnt untouched and therefore not willing to let me upgrade it. And I actually really need a step by step help since I really forgot all the commands...

Thanks so much for your help guys!

I tried to start twrp (turned it off first, then Power + volume down for a few seconds): in fastboot i choose Recover but then only the broken Android with Fehler (error) appeared.

Now I'm confused what happened to my twrp. I for sure used it under KK, maybe I lost it while updating to Lollipop? (or maybe I never installed it and I mix it up with another tablet i have...) how can I find out if twrp is installed.

Thanks so much for your kindness!

I now found out that pressing Power and Volume up while the broken Android is visible I at least can reach the recovery. But still no twrp (at least how I used to know it).
[MeMO Pad 7 General] Ruben Craveiro:
you couldnt use twrp on this tablet on kitkat by choosing option to boot into recovery... you would need to flash twrp and flash ESP partition which kk doesnt have.. so ur mixing devices like u said or you used temporary recovery session.. anyway, follow the tutorial on how to fix bootloop when updating from kk to lollipop (its on me176cx general forums i think)
[MeMO Pad 7 General] tim_h:
The following is what worked for me (also with a modified .24 system image):

The official ZIP files are available on the ASUS webpage: https://www.asus.com/support/Download/28/6/0/23/3HzHuNmdcAgeMhJ1/32/

Get the official .33 ZIP (Lollipop to Lollipop): http://dlcdnet.asus.com/pub/ASUS/EeePAD/ME176C/UL-K013-WW-12.10.1.33-user.zip

Put it in the root of internal storage.

Reboot the tab.

A notification should appear that a system update file has been found. Open the notification and a dialogue should start that offers to install the update. Follow that through. (The tablet might need to be charged to a certain level or better plugged in with the charger to start the process.)

The tablet will reboot and install the firmware update. I think it will only work with the stock recovery (which you seem to have), not with TWRP installed.

If that works, repeat the whole procedure with the .36 ZIP: http://dlcdnet.asus.com/pub/ASUS/EeePAD/ME176C/UL-K013-WW-12.10.1.36-user.zip

In fact it might be possible to directly flash the .36 image from .24. But I am not 100% sure.

As far as I know, the ZIP files from the ASUS page cannot be flashed via TWRP. There are repacked images around that should be flashable via TWRP, but I had problems with them, so would recommend using the official ZIPs instead.
[MeMO Pad 7 General] LuctenFinger:
that s exactly the problem I faced.........

you know , the CN version stop OTA now

so the last version of CN is .201

so there's nothing I can do about Lollipop until I figure out how to flash into WW version :(

P.S. how is your boot.img project?

I get the zImage

source code of the c program sounds like that:

char a[16];

for (i=0x3600; i<0x6e5f90; i+=0x10)

{

fread(a, 1, 0x10, fboot);

fwrite(a, 1, 0x10, fzImage);

}

but I don't know how to unpack the file in zImage

any tutorial for that?

Nope...the battery drain is still there. Tested with Wi-Fi off and Android OS process kept the tablet awake for 30 minutes and so, the battery is still draining. Restarted the device and trying again just in case, but I think it won't help with anything.

They begun uploading 183 firmware to the support page. The Chinese version is up.
[MeMO Pad 7 General] ardicli2000:
I have managed to understand the battery drain issue.

It is definately a wifi power management issue.

What you have to do is:

1. Do not use any Power saving mode. These modes keep wifi running all the time.

2. Get into wifi advanced settings. Choose the option "Keep Wifi Open during sleep" as "only when plugged" (these words may not be the exact since i am not using english on my tablet). And untick "wifi scan can be used all the time by google apps".

So that when you turn of the screen, you will see that the wifi will be off after 5-10 minutes. Sync is still there but a bit late of course.

If you turn off wifi and turn on airplane mod during night, you will see that battery will drain at most 3% during night.

Since there is not any Mobile Data , I assume "push sync" is not a main feature of this device. So it is acceptable, at least for me, to turn wifi off during sleep mode.

Regards.

---------- Post added at 12:21 PM ---------- Previous post was at 12:17 PM ----------

It is not available at global website and a couple of local site but German site.

Interesting. Waiting eagerly for WW version :)
[MeMO Pad 7 General] zapz:
You got the problem backwards...the problem is that when WIFI IS OFF the battery drains...when WIFI IS ON, it doesn't. So keeping Wi-Fi always on lowers the drain , keeping it off will increase it ( Android OS process is always kept awake when Wi-Fi is off, this is the culprit that's draining the battery).
[MeMO Pad 7 General] ardicli2000:
[MENTION=4815712]zapz[/MENTION]

This is not the case for me. Not at all. See the picture below.

Besides not to allow google to use wifi signal to detect your position would be another solution. This is also what i did.
[MeMO Pad 7 General] zapz:
I tried almost any combination possible : having all applications up to date, unstalling the applications and having them only on factory version, disabling applications, disabling power saver, I tried all the Wi-Fi settings, I turned off account sync, I did factory reset 3 times...and other things that I can't remember at the moment, but I tried anything I could think off...and still the same result : Wi-Fi off = battery drain.

The first time I had this problem was on another Asus Memo Pad 7, the first one that I bought. After trying everything I could think of, I took it back and they gave me a new one, the one that I currently have....but the same thing was still happening. And I'm not the only person having this problem. Good thing that you don't have problems with yours though.

I would prefer to find a solution to this so that I can keep Wi-Fi off when I'm not using the tablet, but at the moment I'm just satisfied that the drain is lower with Wi-Fi on. With Wi-Fi off, I lose 25-30% battery over 8 hours, with Wi-Fi on, I lose only 3% or so over the same amount of time. Or so it used to be, before the update. Now it seems that the drain is higher with Wi-Fi off, will test and see if it's still the same when the Wi-Fi is on or if that one is higher as well.
[MeMO Pad 7 General] Hag77:
I've tried many of these options too, and it just doesn't matter what power saver, wifi mode, etc I try-- Android OS is *always* on top of the list and responsible for major battery drain.

Can you explain what update and what was successful?

I just manually checked for an update and it found .182. It downloaded, checked the file, and rebooted, but then I got the little broken robot picture, it said ERROR! and rebooted. I am still at .161 now, and it said the update was not successful.

Are you talking about updating to .182, and if so, how did you do it? I am rooted (but so are you, apparently) and it is not working for me via manual update in Settings --> About...

Sounds like this update has some cool stuff, so I'd like to install it if I can. Just want to do it the best way possible and hopefully maintain root...
