[MDA II, XDA II, 2060 General] saulysw:
Hi all.

I have a fairly bad problem and I have a glimmer of hope that someone here may be able to help me. This will take a minute to explain, so please bear with me.

We have a fairly large fleet of sales people using xda II models, have done for 6 months. Our solution included them syncing each night from home phone line, using a bluetooth (billionton) modem. This works fine, it's cheap and cheerful. GPRS sync is too $$, by the way.

So, now we get a new client, and need to buy more units, but we can only get the IIi model, as the II is obsolete. The IIi has 2003SE instead of 2003, which has some fairly annoying changes in it (eg invisible icons in .NET CF apps toolbars, but I digress). The most alarming is that we can not bond to the bluetooth modem. When I try, I get "There is no bluetooth hardware installed on this device". This is obviously, um, complete crap. By the way, using the Bluetooth manager I can talk to the modem, I just can't search for it using the "new.." text in the my connections setting once I have selected Bluetooth as the modem.

A full path to the problem is start menu : Settings : Connections (tab) : Connections (icon) : Advanced (tab) : Select Networks (button) : "My Work Network" Edit (button) : New (button) : Select a Modem set to "Bluetooth" then Next (button) : "New.." (text) = Error.

On the xda II, this same sequence starts the search for the device, which it then finds and you can bond with it, linking the connection to a bluetooth modem as desired. On the xda II, you can also do the same thing in the bluetooth manager, but you can't, it seems in the IIi.

The IIi has, according to the Start : settings : System : device information the following -

ROM Version 1.11.00 WWE

ROM Date 01/27/05

Radio version 1.00.00

Protocol version 1337.39

ExtROM version 1.11.923 WWE

OK. Now, my question to you - is there any way to simply fix this (eg a reg hack)? Or perhaps can I load up a new bluetooth stack or ROM? Or am I just plain screwed. I know you guys know your way around these units, so I'm hoping it's not the latter.

Thanks!!!!!

[General Questions and Answers] truckerd:
Have been using Motorola phones for the past 15 years or so, just because in general the call quality and build has always been better for me. Just recently bought a Note 3, was a great phone until I had issues with the sound quality, it sucked. I returned it. [ though apparently there was a Samsung software fix for that ] I'm a truck driver and have a Bluetooth hung on my ear for the better part of 12 hours a day, $ 2700.00 federal fine, no questions asked if not using hands free. So call quality is important. Went back to a Motorola Droid Maxx. I have always rooted my phone, changed the entitlement and eliminated all the bloatware. Rooted the Droid Maxx, but with the new Kit Kat that screws up the root, which there is a new root. I'm getting so tired of re-rooting the phone every 6 month or so, [every time there's a new android up date.] What I want is to get a phone that I can install a custom Rom, keep using my unlimited data and not mess with the phone every 6 months or so......don't mind out right buying a phone. So what phone to purchase ? I have always needed a large screen, big battery. And most important good call quality. Apparently the Droid maxx can't be unlocked yet. So what other choices do I have. Galaxy s4 ? Do I purchase a developers addition, unlocked. Need someone to walk me through the process. Not completely sure what ROM to install, was recommended to install Cyanogenmod ? Need some feedback from the Pros.
[Android Q&A, Help & Troubleshooting] Borden Rhodes:
So after a failed attempt to upgrade from CyanogenMod 10.1.3 to 10.2, I was unable to access /data or /sdcard because both systems were encrypted. I ended up having to factory reset my phone because it refused to co-operate or let me access my files. However, before I did that, I was able to run

adb shell "dd if=/dev/block/mmcblk0p2" > data.img

and

adb shell "dd if=/dev/block/mmcblk0p3" > sdcard.img

, which appears to have copied the raw partition images from the phone (at least, they're the right sizes).

According to my reading, Android (and, I'm inferring, CyanogenMod) encrypts filesystems using dm-crypt, with a AES-CBC ESSIV:SHA256 cipher, with the key being derived from the password using PBKDF2. Knowing the precious little I do about encrypted file systems, my guess is that if I configure the image in cryptsetup to create a drive mapping, I can mount the mapped drive and recover the data from the images.

According to /fstab.herring on my ahem, fresh, install of Android, the /data partition is in ext4 format whereas the /sdcard partition is vFAT. So, once I've gotten through the encryption on the partition images, they should mount normally, right?

I know that dm-crypt accepts plain, LUKS, LoopAES and TrueCrypt device formats. I'm inferring from the PBKDF2 extension that Android goes the LUKS route for encrypting. Is this conclusion correct?

Could someone explain whether it's possible to decrypt a dumped android image? I'm really hoping that the cypher information is stored on the file system and not on some key file that I nuked in the factory reset. If it can, in theory, be decrypted, am I using the right tools to approach the matter? If so, I'll continue fiddling with cryptsetup and mount, but no sense in wasting time if it's an impossible task.
[Android Q&A, Help & Troubleshooting] Borden Rhodes:
Never did get a response to this question, so I'll try it again, but start with a simpler question:

If someone dds an Android (specifically Cyanogenmod 10.x) partition to an img file, is there any way to read that image from, say a Linux laptop? I dumped the contents of the /system partition using

adb shell "dd if=/dev/block/mmcblk0p1" > system.img

I expected system.img to be a normal ext4 partition. However, attempting to loopback mount it with

sudo mount -t ext4 -o loop,ro system.img ~/android/system

Gave me errors about corrupt group descriptors, bad magic numbers and other maladies indicative of a thoroughly corrupted file system. I'm assuming that:

/data has the same ext4 partition structure as /system; and

The process to mount /storage would be no different to mounting /system with the exception that the former uses vFAT as its file system

However, as my Android is currently working normally (well, as well as one can hope for Android to work), I know I don't have a corrupted file system.

So what's going on? Does Android use a special version of ext4 that other Linuxes don't recognise? Am I not dd-ing correctly? Is there a block-size issue I ignored to my peril?
[Android Q&A, Help & Troubleshooting] saidelike:
Can you give the result of the "file sdcard.img" and "file data.img" commands?

You are quite right. With regular LUKS container/partition, you would do (being root) the following. With the following commands, you can create a container named "safe", setup it, then format its content in ext3 and mount the partition:

dd if=/dev/zero bs=1M count=50 of=safe
losetup /dev/loop0 safe
cryptsetup luksFormat -c aes -h sha256 /dev/loop0
cryptsetup luksOpen /dev/loop0 safe
mkfs.ext3 /dev/mapper/safe
(losetup /dev/loop0 safe)
(cryptsetup luksOpen /dev/loop0 safe)
mkdir mnt
mount -t ext3 /dev/mapper/safe mnt
//HERE: do whatever you want in your mounted encrypted filesystem
umount mnt
cryptsetup luksClose safe
losetup -d /dev/loop0

For details, you can go there: http://blog.theglu.org/index.php/20...-couteau-suisse-du-chiffrement-de-partitions/

Sorry, the article is in French but you can translate it if you need to.

Here, using "hexdump", you can see the "safe" file has a LUKS magic at the beginning. And doing a "file safe" command, you can check it detects it as a "LUKS encrypted file".

If doing "file" on your .img files does not give you the same result, you may not be able to directly use the "cryptsetup" command and need to adapt it.

Finally: usually in Android the header containing the key is stored on another partition so you may have lost it when wiping your phone, sorry.

---------- Post added at 02:44 PM ---------- Previous post was at 02:41 PM ----------

Can you give the result of the "file system.img" command?
[Android Q&A, Help & Troubleshooting] Borden Rhodes:
Thanks, saidlike, for your reply:

sdcardPartitionDump.img: data

data.img: data

system.img: Linux rev 1.0 ext4 filesystem data, UUID=57f8f4bc-abf4-655f-bf67-946fc0f9f25b (needs journal recovery) (extents) (large files)

Again, attempting to run

mount -t ext4 -o loop systemimg mountpoint/

yields

Ignoring the results of data.img and sdcard.img for the time being, the fresh dump of the system partition shows that it's an EXT4 filesystem, but that it's heavily corrupted. fsck.ext4 on that partition basically asks me to fix every single inode, so it's not a simple unclean journal issue. Therefore, is it fair to conclude that CyanogenMod (and maybe AOSP too) have modified the ext4 partiiton type?

Maybe, my reply is too late, but you could try to make the same experiment with backup of your current data.

If you get the same results as with the old pre-wipe backup, then you still have a hope.

Alright, bit of a noob here in regards to the new mk2 update. I'm trying to get this done and keep running into brick walls.

Problem: Have to flash stock recovery and unroot my s4 to get the OTA or sideloaded mk2 update. Have no stock rom with which to flash. Sammobile doesn't have the firmware available for download to reflash stock everything on my phone.

1) Do any of you most awesome people have a link to a downloadable stock unrooted mja ROM that I can flash on this phone to restore stock recovery?

2) Is there a way to restore the stock recovery without flashing the stock rom?

I searched and couldn't find an unrooted ROM. Any help would be appreciated! Thank you!

[Android Q&A, Help & Troubleshooting] mraeryceos:
I was thinking of the coolness factor of just having one device, a phone, to which you could connect an external display and have an extended desktop. I am not finding any reference to this on Android (only the MS Surface). From what I have been reading, and remember/understand (may be confused), Jelly Bean brought the ability for windowing apps. However, the apps have to be coded for the capability, unless you root your phone and installed an app that provided windowing for all apps. Also, I have not heard of the possibility of having an extended desktop in Android.

I would like to ask WHY? Why not have windowing and the ability for an extended desktop, on an external display? A bluetooth keyboard and mouse just follows. Does google have to play nice with the manufacturers that stand to loose from people only needing one device? Is there a reason I'm not thinking of? Most phones are fast enough for this these days.

At the turn of the century, I was running GPS software Deluo Routis on a Sony Vaio 505 Pentium 200Mhz laptop running Win98. The 2-D graphics were smooth even while playing mp3's through the car speakers. The mapping software showed the map clearly, and effectively gave me navigation. People have lost sight of how much you can do if you give up the bloat and bling.

Also, I am pretty confused with the merging of Android and Chrome. I never liked Java to begin with; my experience with it is in MS Windows, and it runs slow as molasses. I believe my phone would run much faster if they had not chosen Java. I understand this to be because you have an operating system running on top of another operating system. It just makes more sense to me to have less layers and run apps natively, for better performance. I thought maybe they chose Java for its level of security. Is the screening process for Google Play not foolproof enough?

I like the philosophy of Google better than Microsoft**, so if one of them is going to win, I hope it's Google. I'm hoping Google won't end up with a convoluted Android/Chrome operating system because Lawyers forced them to (the idea I get based on the latest news). I don't understand: do they want to keep their OS architecture simple, but are being forced to make the OS complex for different reasons?

**Apple doesn't even want to compete. They have never wanted to dominate, just make huge profits. Unless they break up the marriage of hardware and software, they won't win. Then again, if Samsung keeps dominating, there may not be much hardware diversity?

Oh, and my main question was: "Why not have windowing and the ability for an extended desktop?". Wouldn't that be a big deciding factor for anyone that wanted to simplify and just have one device?
[Android Q&A, Help & Troubleshooting] mraeryceos:
Anybody? Tell me I'm crazy at least. There has to be a strategic reason, that Google does not introduce full windowing and extended desktop support.
[Android Q&A, Help & Troubleshooting] E_Phather:
Its coming eventually. though you could do it right now. Motorola tried something like this with their atrix lapdocks.

Chromecast is not "open" to third party apps. http://www.minyanville.com/sectors/...eeds-to-Tread-Lightly-With/8/28/2013/id/51502

Do they have a displayport version of Chromecast? *cough*

quote from: http://www.tested.com/tech/set-top-boxes/457036-testing-google-chromecast/

"Chromecast is also not a particularly good desktop mirroring option, either. It actually can't do full desktop mirroring, and instead works solely with the Chrome browser. In beta right now is Chrome tab streaming, which sends to Chromecast everything that can be rendered in a single Chrome tab, including web pages, flash embeds, and even full-screen MKV video files if you have VLC installed. I like that Chrome tab streaming works independently of what's showing on your laptop or desktop's screen--like with YouTube and Netflix, you can multi-task and switch to other tabs or windows while one tab is being streamed. The only thing that matters is the window size and screen resolution. Chromecast will automatically scale the aspect ratio of your window to fill up your TV screen, adding black bars on the sides to avoid stretching. A full-screen resolution of 1440x900 looked good on a large 1080p TV, but streaming from a 2560x1600 monitor at full-screen made the text unreadable on my 70" TV."

Wow... I thought only displayport was capable of 2560x1600 (edit: hdmi v1.3 brought this). Even if I hook it up to my 2560x1600 monitor, it won't really display anything but entertainment. Chromecast doesn't seem to be a way to have a monitor, to use your Android phone as a PC replacement.

However, I still need to add some kind of wifi enabled device to my 30" lcd monitor (like with chromecast). Really, I don't mind a cable connection from my phone to my monitor, if that was an option. If Google continues to be closed like this, then I would go for Ubuntu phone.

Displayport:

Any phones have this besides the Google Nexus 4? Actually, I'm not getting a new phone until I know what the hell will happen with Android / Chrome OS

Quote from: http://www.tested.com/tech/android/457205-mhl-vs-slimport/

"SlimPort's support for the DisplayPort standard--specifically Mobility DisplayPort--means it can output video at the same 4K resolution as MHL, though not via HDMI (yet, anyway). And here SlimPort hasn't really made good on its potential, yet; though it's based on the flexible DisplayPort standard, the only SlimPort adapters currently available are for VGA and HDMI connectors. The upshot is that you won't be plugging a Nexus 7 into a 1440p DisplayPort computer monitor anytime soon." http://www.slimportconnect.com/

A dock from Samsung Galaxy phones. Has USB ports, HDMI, and audio.

http://www.samsung.com/us/mobile/cell-phones-accessories/EDD-S20JWEGSTA
[Android Q&A, Help & Troubleshooting] SmilerOnline:
I tried that myself with my previous Galaxy S4 (i9500), It was a great dock and when I connected my wireless KB & Mouse USB dongle & connected the HDMI to my PC monitor it was a good experience when doing things like playing GTA3 on the bigger screen (it was better than the windows version in some ways).

But the device just needed a separate home screen UI to be output to the PC screen to look perfect and to work better with the KB & Mouse input type.

It shouldn't be too difficult to make a UI that simply changes the size of some buttons to a smaller size, enabling more widgets to fit on the home screen and if they could simply force the apps to run in either windowed or full screen that would enable better multi-tasking, then the browsers would just need a small update to detect if the device is running in Desktop Mode if so, then simply zoom out of the page a little to emulate the desktop browser experience.

Just a few ideas... If Google's Android team are reading this, I would recommend that you get that dock to experiment with for future Android builds.

Especially now that OS' like Ubuntu Phone are looking at going down this road of the one device fits all computational needs.
[Android Q&A, Help & Troubleshooting] SmilerOnline:
Rather than creating a new thread I thought that it would appropriate to bring this topic back up after the recent announcements that several OEM's have made, that they will be releasing desktops with Android as their Primary/Secondary OS.

I hope that this pushes Google into creating a dedicated desktop UI in the future.

I used to switch the SIM cards manually in my old GNex, but this has become much less convenient with the SIM tray in Nexus 5. So I've decided it's time for a dual SIM adapter. Such as magic-sim, for example?

Has anyone tried it? Is it convenient to use? Does it fit with all cases? What about standing cases such as this one?
[Nexus 5 Accessories] JCreazy:
I am curious about this too. The magic sim says it is compatible with the Nexus 5 but I wanted to know if anyone had tried it.

I've been trying, without success, to put where the sim and the piece under where the info of the sim card reads but keeps saying no sim card. I do have an easy time pulling the sim card out with the piece on the adapter.

[Nexus 5 Accessories] dodsonhaycattle:
I could post some this evening for sure.

It gets placed over the microsim in your phone then they together get put in the Sim tray and then folded over. Its paper thing so you slide that into the phone so you then have the second Sim dangling around. You put a full size Sim in slot two and bend it over the back side of the phone and sandwich Sim two in between the phone and a case. Its fairly thin and fits with the play store bumper well with just a little bulging.
[Nexus 5 Accessories] ZeGuitarist:
So you tuck the second SIM in a case, instead of the phone itself... Thought as much, I had no clue as to how it would work otherwise.

Dual SIM adapter from .magic-sim com

Hi!

I've purchased Dual SIM adapter from magic-sim.com

It said the adapter was compatible with Nexus 5.

But now I realized that the phone does not have STK (SIM Tool Kit) - the application to switch between SIMs.

But it seems that the Nexus 5 detects the adapter because after applying it "SIM-1" appeared on top of the display.

So how to switch between the SIMs???
