If it says "waiting for devices", it means it cant see the device. When you boot into bootloader, the first command you trype should be "fastboot devices".

I would recommend ditching the SDK and uninstalling the drivers then setting your computer up the way I satet in my "Adb and fastboot. What is it?" thread, which you can get to via my signature link

Hi all,

I've tried everything I could find on the internet to app unlock my M3000. But still no success. :(

Is there anyone that has a solution for me??

did you read well enough then ?

coz it says on this topic here that your device is a wizard

Wizard

Also known as Qtek 9100 / I-mate K-JAM / MDA Vario / O2 XDA Mini S / SPV M3000 / Cingular 8125 / T-Mobile MDA / Dopod 838 / VPA compact II

now the only thing u have to do is find out wheter it is a G3 or G4

And where can I check if my device is G3 or G4??
[8125, K-JAM, P4300, MDA Vario Software Upgrading] da_jojo:
how about u start reading the thread and find out ?
[8125, K-JAM, P4300, MDA Vario Software Upgrading] Miamiboy:
I did everything exactly as described in the thread, but still I'm unable to run uncertified applications on my MDA.

I'm really confused. Am I doing something wrong here??
[8125, K-JAM, P4300, MDA Vario Software Upgrading] da_jojo:
nope... theres a cab file for that..

you can upgrade your wizard now to a custom rom and then u be able to run those unsigned stuff
[8125, K-JAM, P4300, MDA Vario Software Upgrading] Miamiboy:
Could you please tell me where I can find that CAB file?

Been searching all day yesterday....

ehh geen idee gast :P

maar als je gewoon die nieuwe rom 3.2 van molskii dr op zet dan ben je dr ook en loopt ie een stuk sneller imo
[8125, K-JAM, P4300, MDA Vario Software Upgrading] Miamiboy:
Dan ga ik dat maar eens proberen, want hier wordt ik niet goed van. Heb echt alles al geprobeerd.

Ben nu die 3.2 aan het downloaden, laat wel weten of dat gewerkt heeft.
[8125, K-JAM, P4300, MDA Vario Software Upgrading] da_jojo:
ja als het je puur om die applicaties draaien gaat daar is een cab file voor om die cerficatenshizzle te unlocken en die zit in die rom.. alleen dies voor versie 2.x niet te unlocken zonder dat ie naar de klote gaat dus ik kan je dr ook nie aan helpen. misschien dat je em uit een losse extended rom kan plukken.
[8125, K-JAM, P4300, MDA Vario Software Upgrading] Miamiboy:

Ga maar even opnieuw die 3.2 erop zetten

Hard reset is toch Comm als Voice toetsen ingedrukt houden. Druk terwijl je de Comm en Voice toetsen ingedrukt hebt met de stylus in het soft reset gaatje gedurende zo'n één seconde. Blijf de Comm en Voice toetsen ingedrukt houden totdat je een confirmation scherm krijgt. Druk nu op de Talk toets (het groene hoorntje) om de hard reset te confirmen.

[Nexus 5 Q&A, Help & Troubleshooting] iliass01:
I don't know what it is but something keeps making files called: AT0000X-X. And the X is a ascending number (see screenshot). It keeps making them!

I have already deleted them but when I checked back 10 minutes later they came back.

Is there an app/program to see which app is making these files? Or does somebody knows what the problem is?

I'm running the latest CarbonROM on Nexus 5

Thanks in advance
[Nexus 5 Q&A, Help & Troubleshooting] danarama:
ATT stands for attachment. Its the same attachment over and over again. The -x signifies it is a copy of the same file. If you download image.jpg then you download image.jpg again, it becomes image-1.jpg etc.

Since it is ATT, an e-mail client sounds most likely. I take it you've done a full reboot?
[Nexus 5 Q&A, Help & Troubleshooting] iliass01:
Yes I did and I wiped cache and dalvik cache. But I thing it solved it now
[Xperia Z3 Compact General] dahod:
It's just an idea but if we can access on the entire hard disk, I think it's possible to recover DRM.

It exists softwares to recover datas deleted. Maybe a way to explore.

Everybody knows datas are never totally erased.

Have discuss

Ps : sorry for my bad eng
[Xperia Z3 Compact General] Bäcker:
This is flash memory. If they delete it and afterwards send the command to trim or gc then it's gone for good.
[Xperia Z3 Compact General] dahod:
The unlocking process is too fast, I do not think they are rewriting the partition. I think they only remove the DRM then dalvik cache / cache and reboot the phone.

But I could be wrong.

I tried different software, they are effective on my SD card.

But my problem is that I do not see the internal hard disk of the phone, so I can not try it.

My phone is boot unlocked. No root / No recovery

[Xperia Z3 Compact General] cschmitt:
The tools that are used to recover deleted files from a file system operate on the premise that deletions are performed by marking the sectors allocated to the file as 'free' in the allocation table without actually erasing the file data contained on the disk. Recovery tools can scan the entire disk to discover file chains and then rewrite the recovered data to some other device.

These tools will not work on the Trim Area (TA) because it is not a file system, but a raw partition that is accessed by directly reading/writing data at known addresses. There is no allocation table or file chains to recover.

The DRM keys are deleted when the bootloader is unlocked by overwriting the key data with 0x00 or 0xFF. This can be verified by dumping the TA partition of an unlocked device and examining the raw partition.
[Xperia Z3 Compact General] matapo:
That makes perfect sense. Taking things one step back, why shouldn't we consider rewriting the DRM keys to the TA though? They're consistent among Z3C devices after all...Is there a bootloader validator that will just overwrite the keys again? Or preventing the overwrite in the first place, rather than worrying about an impossible recovery of the deleted key data?

If neither is possible, could you explain why please?
[Xperia Z3 Compact General] cschmitt:
We don't have the keys because w/o root we cannot dump the TA partition. If bootloader is unlocked to gain root, keys are wiped.

The assumption that the keys are common among all devices may not be correct. In previous Z series devices restoring the TA partition from a different device would brick it. This indicates the TA contains some device specific signature, etc. The keys could be protected with device-dependent public/private key encryption tied to IMEI and some private key. If Sony went to the trouble of protecting their IP with DRM, they are going to protect the DRM keys as well.
[Xperia Z3 Compact General] dave_speed:
i thought with towelroot you can root without bootloader unlock ? if not, we just need a possibility to root without bootloader unlock and than we can backup the keys ?
[Xperia Z3 Compact General] Bäcker:
yelp, only that needing JUST a way to root without unlock sounds so easy while it's not.
[Xperia Z3 Compact General] Iruwen:
TA.img is exatcly 2MB, writing 2MB of zeros to flash memory only takes fractions of a second.
[Xperia Z3 Compact General] matapo:
Thanks for the explanation - much appreciated! Hopefully, someone will attempt the 'almost impossible' and find an exploit or two like towelroot, allowing for root access without compromising the bootloader then. Seems like our only option. Sony hasn't made this easy...I can understand why our fellow users are upset.
[Xperia Z3 Compact General] Iruwen:
Just so people don't get confused: that doesn't mean that the DRM keys can be recovered when the phone was already unlocked, but they can be restored if a backup is made before.

PS: and restoring the keys automatically relocks the bootloader which means they can only be used by stock roms iirc. At least that was the case with RomAur I've been using, restoring the keys resulted in a bootloop.
[Xperia Z3 Compact General] dahod:
Thank you all for your explanations, I hope that a great mind will find the solution for those who have already unlocked.
[Xperia Z3 Compact General] endlesstrail:
For the root exploit on the older Z devices, did the exploit work only on certain firmware versions, or could it work on most or all of the versions?

I'm asking this because I've for the notification for a system update, but I've been holding back on installing the update, thinking that perhaps any exploit might be patch in newer versions.

Thanks.
[Xperia Z3 Compact General] Iruwen:
Only specific versions. But it was possible to downgrade, root and then upgrade while keeping root. Towelroot then worked with various versions that used an affected kernel version.
[Xperia Z3 Compact General] someone755:
My brain wouldn't let me sleep last night over this (probably stupid) idea:

If /system can be written to by certain tools (correct me if I'm wrong, but afaik you can flash .ftfs with flashtool with a locked bootloader), would it not be easier to find an exploit there (in the .ftfs)?

Much easier said than done, yes, but sounds much easier than finding an exploit in Android, imo.
[Xperia Z3 Compact General] Iruwen:
I guess tampering with an FTF changes its checksum so it cannot be used anymore.
[Xperia Z3 Compact General] someone755:
Well yes, you cannot alter an ftf, but what if we somehow made a small img of system and tricked flashtool into tricking it's actually just the system part of an ftf?

Flashtool then flashes the rooted system image and viola, root achieved!

You know, just how Nexus devices have a recovery (factory) image for each partition? Why not make this work?

Ofc just a (probably wayy off) theory, but it seems plausible.
[Xperia Z3 Compact General] Dsteppa:
I wouldn't bet on it. The 'issue' has been there since the Xperia Z, the only solution has been to backup the partition before unlocking, else it's gone for good.
[Xperia Z3 Compact General] renaud:
There might be a way to restore the keys without relocking the bootloader. But to find how, you will need to dismantle the phone and have something to read/write directly to the memory (JTAG), and also have a high crypto background as it would be strange if it would be just a bit needing flipping.
[Xperia Z3 Compact General] Iruwen:
I guess it's easier to find a new root exploit :D
[Xperia Z3 Compact General] renaud:
Anyway, you would need a root exploit to first backup the keys (at least for normal end users without a JTAG).
[Xperia Z3 Compact General] kopsis:
As I understand it (someone correct me if I'm wrong), Flashtool doesn't actually do the "flashing". Writing the new image to flash is done by the firmware on the phone (bootloader?) and Flashtool just "feeds" it the image using a specific USB protocol. With a locked bootloader, the phone won't flash an image that doesn't have a valid crypto signature and to get that, you'd need Sony's private signing key.
[Xperia Z3 Compact General] someone755:
Wow this security from Sony is becoming like S-ON was in 2011-12. xD

Is there a way to run a recovery with system-write access, then? I kept seeing these on all of my old devices (save for the Nexi, ofc), but never bothered to ask how they work.

I'm guessing they do require a security exploit to even be written, but I'm really not sure.

Has anyone seen if an adb backup/restore can write to system folders other than /app? I know the default is -system, but that only works with apps.

Crazy idea from this -- adb restore an app into /system/app that writes the su binary where it needs to be (don't system apps have system-wide write access?).
[Xperia Z3 Compact General] marumari:
On previous phones, what happens if you attempt to restore the DRM keys from another phone? Does it just not let you write them in?
[Xperia Z3 Compact General] someone755:
A brick. A hard one, if I understand correctly (aka no going back).
[Xperia Z3 Compact General] kopsis:
You can't flash anything other than a signed image without unlocking the BL or getting root through some other method. Unlocking the BL blows the DRM keys, so that's out. Past tools that work around locked bootloaders have always had to take advantage of an exploit. There are currently no known exploits on the Z3C that will allow one to get root with a locked BL.

The su binary has to be installed with SUID permission and you can't do that using adb without root on the device. The bottom line is that there are really smart and experienced devs working this. If the solution was something simple, it would already be known. Kitkat is locked down pretty good right now. There probably are still some exploits, but they are few and not easily discovered. Maybe someone will find one for the Z3C, or maybe there won't be enough interest to drive the search. At this point, the limitations are well know. If one is buying the Z3C today, assume that you can have Sony DRM protected software or root, but not both.
[Xperia Z3 Compact General] theloniousm:
On the subject of recovering the DRM keys after they were wiped, would a utility like Spinrite be able to read zeroed-out sectors? it has been known to achieve results on flash based memory before. It takes a few (5 and up) passes to completely zero-out sector. Who knows maybe Sony only does 1-2 passes?

Is there a program i can use to extract the music in there?
[Android Q&A, Help & Troubleshooting] AkrumError:
The .files that you have are for everything in the game, including the music

I managed to find some of the music by just sorting these files by size, and then take the largest ones, just drag drop into media player and they would work.

Of course then you can just rename them to .mp3 and you can also edit the tags of you want, no need for conversion though.
[MX Player] ffxx68:
Hi,

I'm having troubles using the stock JB Android 4.1.2 play m3u8 live streaming. Issue described in:

http://stackoverflow.com/questions/26181554/stock-android-h264-decoder-failing-on-m3u8-url-files

After some debugging, seems to me that only the "baseline profile" is supported by the stock SW codec (frameworks/av/media/libstagefright/codecs/on2/h264dec), while the stream has the entropy_coding_mode_flag set (i.e. it is a CABAC encoding - I'm not an expert about H264, but I read it's a rather different encoding scheme).

So, I was wondering if it was ever possible to entirely replace the libstagefright/codecs provided with stock AOSP with the SW codecs of MX Player, which seems to be working fine on the same m3u8 stream.s.

Any idea if ever feasble and, if so, about how to proceed?

thanks

Fabio
[MX Player] ffxx68:
E.g. I was thinking if that was possible by simply hacking the codec declarations in

device/.../.../media_codecs.xml

or if a more complex code integration in AOSP is required. Note - I can rebuild AOSP for my device.

Any advice welcome, anyway.
[MX Player] josuearisty:
I think its not only a matter of software, hardware must supports it.
[MX Player] Thirumalai.K:
Even if you declare, if it's not supported by your gpu then it will simply through a error.

Mx player uses the hardware decoders included with your system. If it's not supported ffmpeg is used. But, it will use the cpu to decode the video.

So, there won't be much benefits.
[MX Player] ffxx68:
I know.... actually, I didn't know ffmpeg was the underlying SW decoder.

I'm afraid my HW GPU doesn't support H264 coded in CABAC. while it does decode seamlessly CAVLC (two flavors of H264 encoding... I found out.).

There will be a benefit in having SW codec, so - at least screen doesn't blank out :)

I noticed it takes 30-35% CPU while using SW MX Player on those streams. Still acceptable (I don't think GPU will use greatly less power). Final quality is definitely OK.

Any suggestion about how to proceed with ffmpeg codec integration in AOSP? What are the main integration points to consider?

thanks

Fabio
[MX Player] CDB-Man:
I'd just like to note that generally, GPU rendering reduces power consumption dramatically. For example, a SW rendered 30min video will use 25% of battery life on a Nexus 5. The same video reencoded to a GPU-supported codec will use closer to 10% battery.
[MX Player] ffxx68:
Just for the sake of informing the audience here, I think I found a very good starting point for this, here:

https://github.com/omxcodec/stagefright-plugins
[MX Player] ffxx68:
I'm working on the porting of the above to my AOSP, but found issues with the integration.. There's something not going well with picture quality. Still debugging (https://groups.google.com/forum/#!topic/android-x86/mTnTe39D5Co).

Meanwhile, let me ask here whether there's any documentation, about how to access access the MPlayer SW codecs from other apps, or AOSP libstagefright.

thanks

I currently have an AT&T Rooted GS3 running 4.1.2 with CWM Recovery. I use Titanium Backup and have schedules to do automated backups 3 times per week (keep last 2 backups of all apps & data). I have Frozen several of the Samsung and AT&T crapware apps. I would like to upgrade to an AT&T GS5. At the end of the process I would like my GS5 to be rooted (need root for Titanium Backup and AutomateIt Pro) with stock TouchWiz and get all my apps and data back that I am currently using on my GS3. I'm looking for input on the best way to accomplish this task.
[AT&T Samsung Galaxy S 5] ChinDaChin:
Well its really simple. Go to the sticky thread that shows you how to root the S5. Make sure you take the update for the newer firmware, and then download towelroot. Once that's done, just run towelroot and you'll have root access. From there you need to select a ROM. I don't think cwm supports the s5(yet?). Then you'll need to setup your custom recovery and install the ROM. Lastly you'll setup titanium backup the same way.

Or you can just towelroot and then freeze all the bloatware using titanium backup.

Bottom line is: read the sticky. It answers all your questions.
[AT&T Samsung Galaxy S 5] s8freak:
You won't be able to run TWRP or CWM on the G900A AT&T S5 you'll have to use Safestrap since the bootloader is locked down tight. Then you'll need to root using this method.

http://xdaforums.com/showthread.php?t=2862299

If you're just wanting to run stock TBU for freezing and debloat you'll really enjoy the S5 since in my opinion it's quite a step up from the S3 which I was a proud owner of myself.

[AT&T Samsung Galaxy S 5] jpcdeux:
Back up all your apps with TiBu. Use root explorer to copy the TiBu folder from your device memory to your external SD. Put sd in S5. Use root explorer to copy back over to phone. Open TiBu hit Menu, reload application so it sees the newly added folder, restore apps. I wouldn't restore data as that causes issues a lot, especially coming to an entirely different phone
[AT&T Samsung Galaxy S 5] hoss9009:
So is it even possible to root the S5 the way the S3 was? Does Samsung really want that much control over their phones that you can't kill the bootloader on it?
[AT&T Samsung Galaxy S 5] s8freak:
You cannot root the S5 as you did the S3 it's actually easier depending on the kernel date. When I got my S5 I June I had it rooted and Safestrap installed in about 5 minutes. You don't have to use download mode or anything. It isn't Samsung so much as the carriers that want the bootloader locked down.
