[NFC Hacking] Sofitos:
Thesis approach

Security seems to be a main concern this days. NFC advantages are aplenty, however no one is really concerned about the security aspect of it. i.e. hacking NFC or being able to track a person by their NFC capable phone etc. etc.

I would show that NFC can be easily read for instance passports, credit cards etc... Show the techniques used to circumvent reading i.e. hashing, pin codes.

In the end describe a theoretical approach that it can make nfc's security better.

In the end you just need to be able to defend your approach against other professors so keep in mind you need to be well aware of the subject.

This is my idea and this is how i would approach the subject. Im sure there are hundreds of other applications out there that you can ellaborate on.

Sounds cool though good luck.

Hi, I have never figured out why whenever i flash i often lose saved contacts or calendar appointments. Could it be a sync setting? like my phone overrides the cloud or something?

I am hoping to finally jump to jellybean today, but i've been afraid somehow i'll lose too many important calendar appointments for my work. Any tips at how to ensure these always stick? I typically sync everything...then flash....then sign in and upon re-sync find things missing!

hey guys I really need help here :crying:

I will tell you guys from the veeerrryyyy begining

my phone is 2 years old (on my hand at least),and there is no problem untill about 3 days ago.

my ROM is GDX 029, have run it for months, no problem. but on that freaking day, when i charge my phone it takes 3 hours to make the LED light become green (battery level 90%++) when in normal condition only take about approx 1,5 hours. it seems very fishy, so i touched it, but it really is heated ( normally not ) and when i unplug the charger and left it to be cooled down for about 5 minutes the battery fell from 92% to 1%. I googled it and some people said that it was kernel, so I reflash the kernel and ROM, charged it once more and walla it heated again. no helping at all:crying::crying::crying:

i have flashed some other ROM and the original SE ROM but it doesnt help at all. can someone tell me how to fix it :crying::crying::crying::crying:

[Sony Xperia P, U, Sola, Go] munjeni:
Because a lot of users not understand procedure in creating right boot image, asking me by pm for help...etc, I going to explain how I doing these things! Here is an simple tutorial for you!

Reguired:

- kernel.elf (from stock rom)

- SonyXperia Flasher (for conversation sin/elf...etc) -> http://androxyde.github.com/

- linux tools (from attachment)

- H&D Hex Editor -> http://mh-nexus.de/en/hxd/ (to compare and learn from pictures)

To understand some thing about battery drain (battery drainage when elf.3 is not inside new boot image)... see Gingerbread boot image thread to figure out some things about battery drainage that we tested and confirmed when elf.3 file is not injected into new custom boot image -> http://xdaforums.com/showthread.php?t=1888247

Ok, it was for GB, lets start now with ICS boot image format (its diferent than Gingerbread, but reguire elf.3). What is an elf.3? Sory I not know, seems something reguired for bootloader???

Every ICS stock boot image contain 4 segments: zImage (kernel), ramdisk, cmdline, and famous elf.3 segment. Without elf.3 we had battery drainage (its confirmed in my Gingerbread thread). Custom boot images not contain these elf.3 (only mine). To understand how many "segments" is inside an kernel.elf (boot.img or boot image) file, open an kernel.elf with H&D and look into this picture:

So there is 4 offsets to segments (kernel, ramdisk and cmdline, elf.3 is not but its 0x70 for GB or 0x90 for ICS). You can manually extract every segment by going to specific offset and copy paste to new file, than saving these new file for example to kernel or ramdisk or cmdline... but its slow procedure and is not reguired because we have tools for automating these procedure.

Here is some pictures how to extract elf.3 and cmdline (reguired files for making new boot image) from an stock boot imge:

- first picture is for extracting elf.3 -> http://img688.imageshack.us/img688/5333/29055229.jpg

- second picture is for extracting cmdline -> http://img201.imageshack.us/img201/7889/10643069.jpg

I will not explain in detail how to extract segments by an tool, but you can do it using this tutorial (extracting manually) or you can do it by SoyXperia Flasher! This tutorial is only for understanding boot image format and tutorial for making new boot image.

To compile new boot.img you need all segments ready, you need tool from attachment "makebootimg.sh", you need Sony tool (from attachment) mkelf.py and tool mkbootfs for compressing ramdisk folder to initrd.gz

Reguired segments is:

- zImage (kernel)

- ramdisk

- cmdline (kernel command line parameters)

- elf.3 (???)

Reguired tool:

- mkelf.py (Sony tool for generating kernel.elf)

- makebootimg.sh (automated script for making new boot image)

- mkbootfs (for compresing ramdisk -> cpio -> finaly to initrd.gz)

To make new boot.img modify makebootimg.sh, change all paths to match paths for your linux folders, than run makebootimg.sh and your boot.img is ready. Hope this part of tutorial help you for understanding something about boot image for Xperia devices?! :laugh:

I don't know where to create initr directory, at what location and run gunzip < ../initrd.gz | cpio -i -d

please tell me correct locations.

Top dir is:

Extracted ramdsik dir(you need to extract ramdisk and put into initr):

/root/android/sony/go/ics/initr

Kernel source code: /root/android/sony/sony_kernel/kernel

Kernel modules is copied to the /root/android/sony/go/ics/tools/modules

Its simple easy to figure out all things by analysing bash script! Its not hard!

So I came across this thread by Spizzy01: (Thank Spizzy01, not me... his idea... all credit goes to him.)

http://xdaforums.com/showthread.php?p=37420432#post37420432

And in post # 16, he mentions about how he contacted Qualcomm to request about updated Adreno graphics libs.. so that maybe we can get the updated graphics performances of ICS/JB while staying on GB. Which I think would be sweet.

So I thought to myself what if we, as many Xperia PLAY users, emailed Qualcomm and asked that they either update the GB libs for the Adreno 205 as the processor is about 2-2.5 years old now, or if they would be willing to release the sources and let our kicka$$ devs here have a field day with the sources.

The best link I could find on their site was this:

http://www.qualcomm.com/about/businesses/qct

Just click on "Contact" and email them your requests for these Adreno 205 Libs.. remember stating either updated graphics libs or releasing the sources.

What are your thoughts......? I personally think its worth attempting, because you never know and if it does work either way its a win for all Adreno 205 users not just Xperia PLAYs.
[Xperia Play General] Slothboy:
Well it is worth a shot, I just gave it a go, lets see what happens :P
[Xperia Play General] Spizzy01:
I've looked into it quite a bit, and Quallcomm have stated that there pretty much isn't a chance in hell that they'll release their sources...

That being said, an update... A sign of hope... Or a push in the right direction... ANYTHING would be better than nothing. And it's unfortunately exactly 'Nothing' that we have received from Quallcomm for well over a year now in terms of GB graphics libs.

The last update (AFAIK) was November 2011, which is the current libs used in most GB ROMs to date.

Since then there have been several updates, however these releases have only been compatible with ICS and JB.
[Xperia Play General] ozzmanj1:
Just a tip, I have looked into this before, and I dont remember which phone it was that was on GB but it got updated GPU libs... and it was running the Adreno 205 processor. I'll see if I can find the thread for it here on XDA and post it below.

I did email Qualcomm as well and asked about this. I know its very likely we will never get a reply, but you never know.

Edit: This isnt what I was intending to find but someone said they flashed the updated Adreno 220 drivers and it worked.... I call BS.... but meh...

[Xperia Play General] Spizzy01:
When looking yesterday, I found that the Huawei U8800 (Ideos X5) was apparently the last device with the Andreno 205 to receive an update to its GB graphics libs.

http://www.gsmarena.com/huawei_u8800_ideos_x5-3596.php

So I downloaded a few ROMs in order to extract the libs and try them on AuroraPlay... I'll continue looking into it when I get home from work shortly. It got pretty late last night so I didn't get round to recompiling the ROM and flashing it.

EDIT: In response to the updated '220' drivers. The Adreno '200' series drivers work on all '200' series chips as far as I know. So it would make sense if the 220 drivers were to work on the 205, as they are technically the same driver.

[Xperia Play General] Spizzy01:
The drivers in the Galaxy W thread are pretty much the same as what we are using now. It is also around the same time our last update was received.

To my knowledge, the drivers from Nov 2011 were actually ported from another ROM/Firmware... Not sure which though.

I'm installing the 8800 libs now anyway, I'll let you know if there's any difference... Or if it boots xD

Edit: Looks like its a no-go. I've tried loads of things, it wont boot with the drivers from the 8800. I'm gonna try a combination of the GB/ICS/JB drivers... See if I can get it to not run like a slug... Doubt it though!
[Xperia Play General] eksasol:
I don't have anything to contribute except that Qualcomm is extremely protective of their IP, they just ask to take down AndroidPolice articles that posted something about Qualcomm. There's isn't much of a chance.
[Xperia Play General] Visa Declined:
My son has a Huawei M886, a phone that shares the same soc as the PLAY. This particular phone got an ICS demo that everyone installed, maybe this rom contains the updated driver you are looking for. I could probably pull the rom off of his phone(I installed cwm on it) but he's still on gingerbread.

[Xperia Play General] Spizzy01:
The driver we are looking for is a Gingerbread driver.

There have already been updates to the ICS and JellyBean drivers by Quallcomm, the aim of this thread is to try and get them to update the GingerBread drivers or for us to find our own alternative.

I'll download a ROM for the M886 and see what drivers are in it.
[Xperia Play General] Spizzy01:
I've just put together this set of drivers from one of the M886 GB ROMs.

I'm at work at the moment so can't test them, but if someone else is free you can give them a try if you like.

Be sure to create a CWM backup before you flash these! They are completely untested!
[Xperia Play General] ozzmanj1:
Going to make a backup now and test. Will report back

Edit: Wont go beyond the Initial (Pre bootanimation screen) So for me just shows teh Lupus Logo,... nothing beyond that..... Id be happy to test future prospect files
[Xperia Play General] Spizzy01:
Aww, that's a shame...

Oh well! I guess I'll move onto the next one. I've got some drivers from fairly recent GB ROM for the Adreno 220 - Seeing as the libs are generic for the 200 series, they may be compatible with the 205.

I'll create an update zip for them and post them shortly.
[Xperia Play General] ozzmanj1:
I have read on other sites where people have successfully flashed adreno 220 GB libs to 205 series an its worked... but these were HTC phones and I dont know if these would work on our phone.

[Xperia Play General] Spizzy01:
Well, the Xperia S has the Adreno 220 - But I'm finding it difficult to get a GB ROM for it.

It was originally released with Gingerbread, but the only available updates are firmware packages... Not ROM's where the drivers would be easy to extract.

I've checked on XDA and I can't seem to find any GB ROMs for the Xperia S.
[Xperia Play General] ozzmanj1:
I know over at the Chinese site Gfan. They have a huge forum there for our phone (Think XDA for China, and yes I know there is a XDA China.. but this is an alternate site, Gfan is massive in China)

And I just read that there are several threads for other phones where they have successfully converted updated GPU drivers to GB, perhaps I may find something there for our phone. I'll take a look this weekend and report if I find anything.

Also, for those interested to know.. on Gfan you do not need to know Mandarin to communicate, all the younger generations in China are required to learn English, so if you signed up you can reply in English and they will understand.
