[Windows Mobile Development and Hacking General] DSX:
I'm planning to develop a simple app for Smartphones generally and my friend's O2 XDA II mini (Is that the 'Magician'?) specifically.

The objective is to allow users to track the number of calls made or messages sent to a particular number or series of numbers which will be decribed by a wildcard string.

Basically my friend's subscription package from his service provider (Hutch) allows for 400 free calls to non-Hutch numbers and 800 free calls to Hutch numbers per month. So practically, all Hutch numbers begin with "9886", so a profile associated with the wildcard string "+919886??????" (+91 is the code for India) can be created by the user and all calls to numbers matching this profile will be tracked. Pretty basic kinda program.

Now, I'm relatively a noobie to Smartphone development - I've done some basic stuff using Visual Studio 2003 (Academic) and the emulator - never with an actual device.

Can anyone tell me where I can get emulator images for the XDA II mini? Further, I would greatly appreciate any advice or suggestions from the community. Better still, if any of you guys already has a program to do this, please tell me :wink: - it would save a lot of trouble!

I'm planning to develop using C# on .NET Compact 1.1

Oh, and any dev experimentation I've done so far was either on the Pocket PC or on the Smartphone. Anything I should know about coding for a device which is a combination of both these types?

Thanks.

hi

this looks like an idea that many could benefit from.. if you are making this application i would suggest you make it so that we (the non indian and non hutch users) can use it aswell...

good luck and keep us posted

I am running CWM 6.0.3.2 and made a CWM backup of my Liquidsmooth ROM. When I am in recovery, I can see the backup file I made if I choose the restore option. I can also see the backup file if I choose "Install zip from SD card" and I navigate to the clockworkmod folder. The problem is, I cannot find the folder where it should be in my sdcard on any sort of file manager. I can use root explorer, root browser, etc. and I have granted all of them root access, yet I can't see the SDcard the way I can in recovery mode and I cannot find my backup folder. I do have the clockworkmod folder in my SDcard, but there is nothing in it except for the RECOVERY_VERRSION file. No "backup" folder. My SDcard in recovery contains the folders 0/ ; clockworkmod/ ; legacy/ ; and obb/ none of these are visible in any kind of file browser, including my PC. Any ideas?
[Motorola Atrix HD] audit13:
When you made the backup, did you choose to backup to an external card? If you just choose backup, the default location is the internal memory.
[Motorola Atrix HD] Neighbor808:
I backed up to internal memory, and I feel like an idiot now that I found it in /mnt/shell/emulated , it doesn't backup to the SD Card that I see in the file manager....
[Motorola Atrix HD] audit13:
Did you choose to backup to the external SD card in the CWM options? I save it to my external 16 GB card all the time.

[Galaxy Note II Q&A, Help & Troubleshooting] srudes2:
Hey,

I was just sitting at the computer and I look at my phone. All of a sudden it shows the bootscreen("Samsung Galaxy Note II N7100" etc).

I felt like... huh that's weird, well maybe something went wrong with Vodafone(They had problems with phones rebooting when getting the network settings for their National Alert system). After having the screen stuck at boot for like 30 seconds I took a closer look. That's when I really freaked out. All of a sudden all kinds of pixels slowly started getting all kinds of red, blue or green colors. Fast I turned off the phone(Power button didn't work even if I held it for 8 seconds). So I took out the battery. Now every time I boot my phone it gives the following screen:

Image can be found at:

h**p://i.imgur.com/bAJaAkN.jpg

Does anyone have any idea what this could be and would it be possible for me to fix it?

If not I will of course send it to Samsung.

Thanks,

Martin

[One (M7) Q&A, Help & Troubleshooting] jaaystott:
Hi there guys,

I suspect I have a battery drain in my HTC One, abd if I don't than this phone is terrible, however I know I do as I have owned several abd this is the only one to act like this :eek:

Anyway I only got the phone Wednesday, so bare in mind it's fairly new. Fully charged it Wednesday night, took it off the charger on Thursday morning barely any usage and it later 11 hours. Sane story today, in fact I went to the cinema and it went from 90% to 59% in under 2 hours whilst power save was enabled and the phone was on standby in my pocket. At one point I put this down to being hot in my pocket, but thinking about it now, it wasn't really hot there.

Anyway I installed a battery stat app and I will put the results in via photo. What it basically tells me is Google Backup Transport is killing my device and Google Account Manager is it's trusty friend. I only installed the battery manager tonight, however these results look pretty accurate granted what they say about the other apps based on usage.

I have disabled some things in my Google account to stop syncing, however my phone backs up to Dropbox NOT Google so I don't understand this drain. Can someone please help? I'm not rooted and running stock 4.2. Thanks.
[One (M7) Q&A, Help & Troubleshooting] sauprankul:
Turn off auto backup. Clear cache for Google play services.

Report back later. You should be able to tell that if a Google backup service is using 71% of your battery, something is up.

And usually people around here use GSam, but w/e.

Hallo, after two days of trying to make kexec working, got it working! Its based on hard boot kexec! We can create now multiboot menu and boot multi roms without need for flashing them! Will make this thread updated including files, kernel and instructions!
[Sony Xperia P, U, Sola, Go] DevSwift1:
and probably now guys with locked bootloader can boot roms requiring custom kernels
[Sony Xperia P, U, Sola, Go] munjeni:
NO because kernel need enabled kexec and reguire some other modifications whick is not exist on stock kernel!!! :(

Tried to boot stock kernel but failed, seems not stable kexec by now! Need help!

Here is kernel changes (3 commits by Aug.09.2013) -> https://github.com/munjeni/android_kernel_xperiago/commits/jb-dev seems there is problem with clean reboot! Got kexec working with usind zImage from the same kernel version but seems when there is another kernel version its fail! I think it fail on my reboot function implementation! Need help to solve these things!
[Sony Xperia P, U, Sola, Go] munjeni:
Got ansfer by self. Stock kernel and everyother without kexec patch ca not be loaded :) more info here -> http://xdaforums.com/showthread.php?p=44077327

Tomorow will make it better, hope perfectly working.
[Sony Xperia P, U, Sola, Go] munjeni:
Ok, lets go multiboot development!

My experience using kexec:

- since hard reboot owerwrite new kernel and ramdisk, I disabled hard reboot. So we need shutdown cpu instead of using function reboot! Since we have no shutdown cpu function we have very slow boot after executing new kernel and ramdisk (curently I am satisfied with slow boot because kexec can boot new kernel and ramdisk, yes its slow but working :))

What is needed for kexec boot:

- kexec can not boot non kexec based kernels

- kexec can boot only kexec enabled kernel which mean only kernel which have my kexec patch (you can patch your kernel using kexec patch from my git)

- suported phones by now is only Sola and Go

My idea for multiboot by now:

- making boot menu based on modified CWM recovery

Modified CWM recovery plan:

- create new recovery and add new sub menu for multiboot feature

CWM multiboot menu idea:

- here we can write kexec multiboot functions

CWM kexec function idea:

- mount system, cache, userdata partition from external sdcard EXT4 partitons and mount them (only if these partions is created by you on your sdcard !!! We can create an small submenu for creating these partitons if these partitons not exist, but not now, we can do it later after creating simple kexec main menu))

- after mounting these partitions we can:

- boot android from allready installed android from these partitions

- ability to install new android to these partiton and boot them

Lets go! Before I start making new CWM, I need better ideas! What you think how we can do it??? Waiting your ideas!!!

Maybe we can do it without using CWM???
[Sony Xperia P, U, Sola, Go] itachilinux:
So, how about another kernel or rom which isn't supporting kexec yet?

Sent from risahikari
[Sony Xperia P, U, Sola, Go] vishnu:
I cannot think of a way to do this without involving CWM. But we could make use of the volume buttons to select the ROM on boot (by mounting the appropriate partition based on the volume button that has been pressed down when the bootsplash screen is displayed). However this would limit us to the number of ROMs that can be installed to two (or max 3, if we have an option to set a default ROM to boot if no button is pressed).

Brilliant work by the way. You are Godlike! :victory:
[Sony Xperia P, U, Sola, Go] munjeni:
Simple not supported!

First of all we need to create ramdisk which will boot android located on external sdcard, than if we get it working we can play with kexec. I need your help! If some one get android working from external sdcard than I will continue further. I am allso playing now with new ramdisk and trying to get external android booting!!

Our multiboot is not ready. Only ready is kexec tool and kexec kernel. Our multiboot feature is not yet implemented. Our multiboot is in plan and our multiboot need ideas!

Changed fstab, recovery.fstab and sony fstab device paths to point to the external sdcard partition, modified updater_script paths, rebooted to the recovery, installed rom to the external sdcard partitions, rebooted, after abnormaly slow boot system booted but is abnormally unresponsive, so I deleted and reverted back to the emmc boot.

Any one have idea what is use of the fota kernel??? Got fota kernel and ramdisk kexeced and booted, found some tools in sbin folder, there is fota tools, for example after exacution of the fota-ua got this output:

What we can do with these tools???

Or another tool:
[Sony Xperia P, U, Sola, Go] XperianPro:
Well have you ever updated Sola with OTA,you will notice it boots to recovery and thats fota kernel "f-ota" - friendly over the air update system
[Sony Xperia P, U, Sola, Go] munjeni:
When I tried on Xperia Go to update trought fota it was not worked! I never seen anything related to the fota recovery! Is recovery exist on fota kernel??? Have any menu???

Found some logs:
[Sony Xperia P, U, Sola, Go] DaniPhii:
I hope it will work on Xperia™ U, I don't know if it could be possible as I don't know how many differences are between Sola's and U's ramdisk and stuff. :/
[Sony Xperia P, U, Sola, Go] mirhl:
well, on xperia s for example we use fota partition like a it was a recovery partition

otherwise as soon as you unlock your bl (= no more OTA) it becomes usless
[Sony Xperia P, U, Sola, Go] munjeni:
How you load recovery from ota partition? Seems you have something like LK bootloader???
[Sony Xperia P, U, Sola, Go] mirhl:
a sort of

newer kernels when booting recovery, check if FOTA partition has the custom one installed

if yes, they loads that. otherwise standard recovery

more information here
[Sony Xperia P, U, Sola, Go] munjeni:
Thats good idea, but thats not ideal solution in comparation with phones which have separated recovery/boot partition and bootloader ui like HTC devices which have direct recovery load trought bootloader, these solution only working if primary boot partition is modified and added "few lines" for booting recovery from seccond partition (like ota partition). Will be perfect solution if we make LK bootloader for separating recovery/boot partition, allso with LK we will be able to create custom emmc layout, by now I can not see any small bootloader for NovaThor on google search, seems thats not public. Searching for a way for creating bootloader based on kernel. How we can modify curent kernel and make them bootloader??? We can modify recovery and make them bootloader kexec based, but I am not happy with kexec because we need to fix them first because loading an kernel trought current kexec patch is very slow! I will be happy if some one look into my git and find a solution for fixing them!
[Sony Xperia P, U, Sola, Go] munjeni:
What about if I relock my bootloader, do I will be able to use fota??? Seems ota working only if drm keys is not broken??

Sony Xperia have diferent things in comparation with Bada, thanks in any way, but I need information related to the Xperia! How its working under Xperia? Any one have updated his phone trought fota? How its look under Xperia? Is there any ui screen during fota update??? ...etc..etc. I tried fota but it not worked because seems reason is broken DRM keys after unlocking. Thats info which I need!
[Sony Xperia P, U, Sola, Go] bobthecooldad:
could you no force one by doing a ftf (gingerbread) update of an old rom after locking bootloader and removing root and changing the build prop so you had your service number and see if it will want to do an ota (Btw i remember doing an ota onto ics and you just started it by selecting update and it downloaded and just showed the settings till it restarted and it was complete)
[Sony Xperia P, U, Sola, Go] munjeni:
Yesterday I relocked my bootloader, than installed gingerbread.ftf, rebooted, go to about phone/updates, but mesage showed about no update for my phone, but I tried Sony PC Companion and it showed me available JB update, than installed JB update trought SPC :(

Did your phone rebooted before ota update?
[Sony Xperia P, U, Sola, Go] bobthecooldad:
cant remeber as it was months ago

did you go in the build prop and change the product number to the one on the back of your phone under the case where it has the imei as they get rid off it or it is a general one in the ftf (found this out on the first ftf rom i installed and it would never let me update)
[Sony Xperia P, U, Sola, Go] mirhl:
you have a lot of ideas in your mind :p

anyway.. your "bootloader into kernel" looks very similar to this

i successfully updated my xs after relocking via SEUS from ics to jb

and a sort of screwdriver-hammer screen appeared after rebooting (cache clearing maybe?)
[Sony Xperia P, U, Sola, Go] munjeni:
Found something very interesting, seems harboot kexec working perfect!

What found?

Main kernel (kernel which exist on your boot partition) must be compiled with removed this -> https://github.com/munjeni/android_kernel_xperiago/commit/d041acbc3f85fd5e940425169a8410dc02edae8b

...than kexec kernel (aka future bootloader kernel aka host kernel aka kernel loaded with kexec tool) must be compiled with enabled kexec_hardboot_hook() which have main reboot function.

When I load host kernel with kexec it loading very slow but good thing is its loaded and working (simple loaded recovery ramdisk and host kernel). Next step was, established adb connection to the kexeced recovery, uploaded new kernel, started new kexeced kernel but stuck on black screen (seems thats reason because I have disabled kexec_hardboot_hook) so I pressed volume up+down+power at same time to reboot phone, good thing phone rebooted to the kexeced recovery :eek: so that mean kexeced kernel is not removed from memory (whick mean phone is not rebooted to the main kernel, it rebooted to the kexeced kernel)!!!

Conclusion is: I think we can load kexec kernel by enabled reboot function (kexec_hardboot_hook) and kexec will working perfectly! I will experiment more, if these thing working I will create bootloader based on recovery, and allso will open it public to git!
[Sony Xperia P, U, Sola, Go] munjeni:
Not working with kexec_hardboot_hook, seems phone is full rebooted by kexec_hardboot_hook and kexeced kernel memory is owerwriten by reboot. We need to find a way for doing cpu reset and need to preserve kexeced memory :( If you have idea let me know!
[Sony Xperia P, U, Sola, Go] mirhl:
could this, this or this help?
[Sony Xperia P, U, Sola, Go] munjeni:
Thanks but no! Allready looked into these posts. Analysed some other kexec patches and found these kexec_hardboot_hook() function is not needed, thats function for showing logo image, for example look into next platform:

So definitelly kexec_hardboot_hook() is not needed because we allready have reboot function and kexec is working. But question is why kexeced kernel booting very slow :confused: Hmmm maybe because my kernel is LZO compresed and need a lot of time to get decomressed?

Edit:

Decompresion is not problem :( Tried uncopresed kernel but strange thing is failed to boot :(

Ideas? Maybe kernel command line need some changes?
[Sony Xperia P, U, Sola, Go] mirhl:
if you try to boot a smaller kernel or a bigger kernel, is there any differences in the loading times?
[Sony Xperia P, U, Sola, Go] munjeni:
Not tried to strip the kernel!
[Sony Xperia P, U, Sola, Go] mirhl:
i said that, because if a kernel 4MB big loads as fast as a 2MB one, that would means that the problems is somewhere else
[Sony Xperia P, U, Sola, Go] munjeni:
Good news for all you, kexec is finally full working, reboot time is beloow 5 seconds which mean we are ready for multiboot feature :D

Created right reboot function and now everything working perfectly!

Guys I have no free time to compile kernels for 10 diferent roms (and maybe more), I will make kernel only for Ex.Se JB rom (Sola and Go only) ! If you need to test our kexec on P and U you need to make kernel changes by self, sory! Kexec tool (compatible for Sola, Go, P, U) you can download from my Xperia Go kexec thread. Kexec kernel changes you can find on my git, simple add to your kernel (or compile mine kernel)... I am busy with bootlader, going to implement simple ini parser where users will define rom title menu, path to zImage, path to initrd.gz...etc.

But if you want I can compile only zImage and kernel modules, rest you need to do by self (ramdisk...etc) !!! Let me know!

if you do compile zimage and modules for p I can make the ramdisk :) thanke a lot:D

Maybe it's too soon to ask such questions, but I am so excited that I will ask anyway :D

In this multiboot feature, will it be possible to launch roms from different platforms? For example, if I want to use Gingerbread, I launch Gingerbread rom, just for gaming, and after that revert back to Jelly Bean roms?

[Sony Xperia P, U, Sola, Go] munjeni:
Of course! First of all kernel which you going to use must have kexec patch! See my git for kexec patch! Next needs is: simple modify ramdisk for example modify them to load system, userdata and cache partition from sdcard :)

I am in final stage with boot menu, added auto reboot option with timer option (popup picture 9,8,7,6...0,reboot :))...etc. I will give more usage info when I finish them
