[Android Q&A, Help & Troubleshooting] Uristocles:
Specifically I have a Note II (SGH-T889) that's dead, but I guess any general Android troubleshooting would be welcome.

• We took it to a battery place that confirms the battery is okay (which also kinda rules out the charging port being the issue). The place also let us try a brand new battery to no avail.

• I've never rooted the phone so the culprit isn't a bad ROM (a lot of troubleshooting articles come from the perspective of a bricked phone due to bad kernel).

• Pulled the battery and left it out overnight.

• Tried hooking up to power without battery in.

• Yanked the external SD card.

• Phone just is completely non-responsive. Straight-up hardware failure?

The almost-too-fantastical coincidence is that it happened on exactly the same day I received my new Nexus 6P and finished configuring it. I wondered if it was some kind of carrier-induced bricking process but I don't think that's the case. My account is still active with the previous carrier and they confirmed everything is cool on their end.

(The user in one of the other articles on troubleshooting was able to get some life by plugging into power without battery; that's not my case.)
[Android Q&A, Help & Troubleshooting] Uristocles:
Also:

• Power cord says "Samsung" so it's not a third party charger

• I take extra care of the phone. It looks like it did when it came out of the box. Not water damage.

• Physical connections all look/seem okay.

Using "Stagefright" exploit CVE-2015-1538 for rooting Sony Xperia Z5 compact?

Hello to the community!

I've seen a video on the Zimperium Stagefright Detector App page in the Google Play Store showing how you can get root access to an Android System. And that seems to be quiet easy - just executing a python script.

So my questions are:

- Is the Sony Xperia Z5 compact vulnerable using the CVE-2015-1538 exploit? (haven#t tested yet on my Sony Xperia Z5 compact device)

- Is it then possible to root the Sony Xperia Z5 compact permanently by changing the neccessary files in the System, maybe manually via telnet?

- Can this be done without unlocking the bootloader?

- Which files have to be changed and what are the changes to get permanent root Access?

Maybe this is a way to backup the TA partition to preserve DRM keys if rooting is not possible with this method. And after backing up rooting could be done by unlocking the bootloader and then applying the root methods described in other threads.

Regards from Dresden

[Xperia Z5 Compact Q&A, Help & Troubleshooting] nilezon:
Yes, according to Stagefright Detector. I could not get Stagefright to work on my Z5C, but that is probably due to my shortcomings.

Probably not. Stagefright will give you "media" or "system" privileges. These users can't remount the system partition to make it writable. Also, Sony have strengthen the security using a kernel module (Sony RIC) that disallows any user (even root) to remount system partition.

However, you could

maybe

(very unlikely) find a system writable executable file in ramdisk and hope for root to execute your modified file.

Afaik, no one have succeeded yet.

Permanent root on this device is rather tough to achieve. You can't modify system partition due to dm-verity (verified boot), and you can most likely not modify boot partition without unlocking the bootloader.

As you say, your best shot is to achieve temporary root by exploiting some kernel module/driver and then dump TA. This is of course not trivial.

There is maybe another way to get both root and DRM features. As system user (achieved using Stagefright), you can query the "tad" socket to retrieve the DRM keys. This is how Sony is reading the DRM keys when verifying things. When you have the DRM keys you can unlock BL, root, and then modify your ROM to spoof "tad" socket responses with your previously extracted keys. Unlikely, but possibly, you could even write the keys back to the TA partition.

This method requires system privileges. If some clever one helps me getting Stagefright working, I could probably extract the DRM keys.
[Xperia Z5 Compact Q&A, Help & Troubleshooting] klausstoertebeker:
Maybe the CVE-2015-3636 is easier to use?

Hi nilezon!

Due to the fact I'm on vacation I can't try to get the CVE-2015-1538 exploit working - my SONY Xperia Z5 compact is at home :eek:

But I surfed the Internet and found another exploit that's maybe easier to be used to get root privileges: CVE-2015-3636

And if I get the document right, a non-privileged app could be used to get root privileges using a pointer use-after-free bug in the kernel. I'm not an app programmer (I just programmed aviation software parts for jet propulsed military planes ;)), but it seems to me that the way described in the linked document is easier to go than the way to use the CVE-2015-1538 - I read in the internet that Sony currently is delivering a patch closing the stagefright exploit.

To find out if my phone (SONY Xperia Z1 compact) and tablet are vulnerable to the CVE-2015-3636, I used the app VTS for Android.

If this is a walkable way and you could write an app, maybe the code for backing up the DRM keys or the whole TA Partition could be included into that app using the CVE-2015-3636 exploit to get even temporary root privileges...

What do you think? :D

Regards

"Klaus"
[Xperia Z5 Compact Q&A, Help & Troubleshooting] nilezon:
AFAIK, the Z5 family is not vulnerable to the CVE-2015-3636 exploit.
[Xperia Z5 Compact Q&A, Help & Troubleshooting] bruno$0:
But the z3+ old firmware is vulnerable. Maybe You can use a z3+ system folder on z5! They are quite same!
[Xperia Z5 Compact Q&A, Help & Troubleshooting] Aeny:
Good job on modifying the script. I could run it on my linux box without any modifications and it produced an MP4. I then moved it over to my Z5C and launched it. After that I tried a reverse shell (netcat -l -p <port>) but got nothing. Then I went out on the interwebs to investigate and here are a couple of pointers.

1. The code is written to exploit the hangouts app specifically. So running the mp4 with any other player isn't going to work.

2. The code is written to take default values if -s and -r are not given to the scripts as arguments. The default values are said to only work on the Nexus device that it was written for.

3. The video you saw was edited to make it look really simple, or another script was run that they didn't show us.

More information can be found in the comments around here:

Happy exploiting, Merry Christmas.

Hey [MENTION=1992283]klausstoertebeker[/MENTION] I have an un rooted stock Sony Z5 Compact that can be used for exploit testing. Wanted to offer it for this purpose before rooting it. If having someone volunteer their "un rooted, bootloader never unlocked-phone" as a test device is helpful then let me know.

Otherwise Im going to root my new phone soon.

Keep up the good work!

Using "Stagefright" exploit CVE-2015-1538 for rooting Sony Xperia Z5 compact?

Hello Joeisgood99!

Thanks for your offer, but I'm not a programmer who takes part in rooting the Z5 compact actively 'cause I'm not experienced with Android programming at all. But I tried to give a thought how a root to this excellent mobile phone could be achieved.

For me using this exploit has become obselete 'cause I accidently did a System update where all the stagefright exploits are closed... :(

You can downgrade your phone using the flashtools to a previous Android version. Dont give up!!!!
[Xperia Z5 Compact Q&A, Help & Troubleshooting] klausstoertebeker:
Maybe downgrade,...

... but to flash firmware you have to unlock the bootloader. And when unlocking the bootloader, you'll loose your DRM-keys.

And the intention to most "rooting" forums is to find a way rooting the mobile phone without unlocking the bootloader to keep the DRM-keys.

And, by the way, if you're unlocking your bootloader you can install a pre-rooted ROM instead of downloading stock ROM's.
[Xperia Z5 Compact Q&A, Help & Troubleshooting] Sadman Khan:
You don't need to unlock bootloader to flash an official firmware.
[Xperia Z5 Compact Q&A, Help & Troubleshooting] Myself5:
You can flash FTFs without any need of unlocking a Bootloader. And while you're at it: use 32.0.A.4.11 Literally everything exept CVE-2015-3876 is vunerable. I just bought a Z5, and looking forward to put some effort into messing with Stagefright rooting ;)

I'm having a Z5 E6653 BTW
[Xperia Z5 Compact Q&A, Help & Troubleshooting] klausstoertebeker:
Sorry,...

... Myself5!

You're right saying that TFT's can be flashed without unlocking the bootloader. ;) But nevertheless I won't downgrade again in the moment.

The reason for me to root my Z5 compact is that I'd like to install Xposed in combination with XPrivacy for security reasons. I want to controll the access of app to my personal data (contacts, calendar, location, etc). But now I found two apps which fulfil my security needs without root privileges:

MoboClean which is relased as working app

SRT AppGuard which is in beta stadium

I prefer the second solution, but in the moment it is still under development. I used it with KitKat and JellyBean and it was really good. And until it will be released as "productive" app I'll use MoboClean.

And the second reason for rooting my Z5 compact was that I want to deinstall those Google apps (and other pre-installed bloatware) which collect my data and "phone home" without my notice. And this can be done without rooting now on the Z5 compact via "Preferences -> Apps", selecting "Deactivate" in the appropriate app tab.

[MTCB Android Head Units General] 1-2-Hak:
You dont need bootloader to flash TWRP. You just need to know how to get there if something goes wrong.

Check this link http://www.freaktab.com/showthread....itions-from-android-No-PC-needed-For-rockchip

get the flash_image from the link.

the get your wifi adb going

do a

adb push flash_image /sdcard/flash_image

adb push TWRP_KGL-7650G /sdcard/TWRP_KGL-7650G

then i go to adb shell

usually just cp them to dev

cd /sdcard

cp flash_image /dev/flash_image

cp TWRP_KGL-7650G /dev/TWRP_KGL-7650G

then flash it

/dev/flash_image recovery /dev/TWRP_KGL-7650G

then if you want to test

reboot recovery

you will need an mouse attached.

I am gong to see if I can get the touch working in this when I get my unit back.

Do a backup of the whole system in TWRP.

Then you are pretty well set.

Not sure if you need original recovery to update new MCU.images. When i uploaded mine I just flashed back the original recovery in the same way.

You can back up the original recovery by the steps in the link above. Which is good to have a complete copy of what you have now before tinkering too.

Hope that helps.

[MTCB Android Head Units General] TT_Vert:
Guy I know this is bringing up a thread from the dead but a question. I did install TWRP but my issue is when in TWRP to do a backup it is only backing up about 60MB of data even w/ all partitions chosen. It shows 0MB in data, is there a way I can back up the entire ROM like you can do on my android based phones w/ TRWP or CM recovery? Also I've read how to switch to stock recovery but whenn I go to TWRP and backup it just backs up TWRP backup files (ext4.win) no .img file is created. I think I just need a copy of the stock recovery.img and then i'd be golden. Am I wrong? If im not, does anyone know where I can find that?

Thanks

If you must here is a website where I got it (although not much you can do with it) be sure to have a mouse as the touch screen doesn't work. If you need to revert, which you will if you plan to update you will need to find a copy of the stock recovery.

Ok, let me get this straight...

1. With TWRP you can't flash mcu.img (but you can flash update.img? how does this exactly work? how do I flash an update.img from TWRP? or do I lose the ability to flash update.img as well?)

2. The ROMs do not come with recovery images and overwrite TWRP? I thought they did, like other ROMs...

last weekend i have replaced my touch screen display damaged, and upgrade my KGL dual core cpu to RK3188 quad core:

I order display replacement and slot CPU from my vendor (25+75$)

Tutorial

1. wait delivery from china ...

2. remove 4 screws behind the panel of unit

3 remove 4 screws to pull up the display,remove the little orange connection of toch screen, then remove 2 svcrews and tape to slot cpu.

4 pull up display and disassemble by removing scotch tape.

5 replace the new touch panel, be very careful don't touch the glass on the inside...

6 lock the display with new scotch tape, re connect little orange connection on the inside

7 assemble all...

for new cpu need to download new ROM with rk3188 firmware like this: http://xdaforums.com/showpost.php?p=60591423&postcount=12068

put on sd card and flash it...

no need to flash new MCU (is the same)

I'll try to revert to old MCU version (2.80) but I will be thankful also for info on signs of failing digitizer (as I also installed the reverse camera and I have also clues that sometimes reversing line may introduce some ghost current into MCU so it may also coincide with touchscreen issues somehow).
