[Q-Solved] Kindle Fire unbricking on a Mac-help request

UPDATE: I added "solved" to the title since I am now unbricked. That said, I do hope someone will pop in and tell me how to run the shell scripts on a mac...

Hi there. I have spent several days searching xda forums, popping into the kindlefire irc channel, and searching google however have not yet figured this out, could use some help.
I have read: the Kindle Fire Beginners Guide, the Kindle Fire Unbrick thread, The Kindle Fire Utility thread (yup the whole thing), and more.
According to the Kindle Fire Beginner's Guide, only 1% of all brick situations are actually a brick, so I'm going to persevere and go ahead and ask for the help, because also according to the guide, if your fire can't be seen as a device then actually it's a brick. To quote: " unless something else was done to the device after the change in bootmode preventing access to adb or fastboot commands. Then it’s actually a brick at that point."
I can't be sure if anything else was done after the change in bootmode so I'll just explain how I got here and hopefully someone can help out.
I have a mac mini running Os x 10.6.8, and the Kindle Fire which was running stock version 6.2.2.
I used the kindlewater root method to install firefirefire and cwm recovery. Was able to boot into recovery by pressing on the power button for it to go orange and then load the recovery options.
Before doing anything at all (and in consultation with St3p_2 of this forum, one of the kindlewater developers), I decided to perform a backup in preparation for flashing a ROM.
so, I booted, went into recovery, navigated to "install a .zip" and chose "backup" at which point I got a message/nag/reminder that this was a permanent change, and I selected "ok". It did it's thing for a while, went into reboot, and I then had the firefirefire logo blinking in a very very slow loop.
It was recommended to me to perform a factory reset by holding the power button for 2 solid minutes, which should then have returned me to stock. Actually, the first time i did it for minutes I went from having a very slow blinking firefirefire to having a rather fast blinking firefirefire. Following a suggestion i then tried it with the kindlefire unplugged. This resulted in a plain black screen until the fire was plugged in again: no boot, no indication of response to use of the power button. Once plugged in, it has gone back to the rather fast blinking firefirefire logo.
I read through the Kindle Fire Utility thread, found the v0.9.2 version prepared for mac and linux, and downloaded it. Although I am not new to terminal, I am not familiar with what command language is necessary to perform the actions required by this tool. If I open the install_drivers.sh with terminal, i get this:
Reverie:~ apple$ /kindlefire/Kindle_Fire_Utility_MacLinux_0.9-1.2/install_drivers.sh ; exit;
This file will install the correct adb_usb.ini file for proper Kindle Fire detection.
cp: drivers/adb_usb.ini: No such file or directory
Done!
logout
[Process completed]
​so I tried running it in the console. I will spare you the output of the console as it appeared to be merely a printout of the actual code of the file and was quite long.
Trying to run the file runme.sh in terminal before running the install_drivers.sh in the console, I got error messages stating there is no such command, or no such file, depending on my command language.
After running the install_drivers.sh in the console, when I try to run runme.sh in terminal, i get this:
/kindlefire/runme.sh ; exit;
Reverie:~ apple$ /kindlefire/runme.sh ; exit;

​Which I affirmed because all the requirements had indeed been set that way on the device before the bricking happened. After "starting" and "waiting for device" nothing happens even waiting indefinitely (more than half an hour) and then it never finds the device.
When I go into terminal and type: "adb devices" I get:

​This result is the same both before attempting to use the 0.9.2 mac utility and after.
I really am stuck at this point, as everything I find with instructions on how to "unbrick" does require that the machine recognize that your kindlefire is attached. Running any of the tools I find requires that basic bottom dollar, which I don't seem to have.
That said, the behavior of "nothing at all: blank screen" when unplugged, and the behavior of "blinking firefirefire logo" when plugged in would tend to indicate that at the very least the device knows it's plugged in and getting juice, and some process is happening when that's true.
Can someone help? Is my next step to purchase a factory cable, or do I have a software solution available to me that I just didn't find in this haystack of solutions?

nothing doing when unplugged seems like a dead battery
would try to charge it with the wall charger for some hours regardless if the orange light comes up - this can last a while

Thanks for reading my guide. I hope it helped you a bit.
Mac OS X is also my primary OS and I take my hat off to you for even trying things this way. I took the easy way out from the very beginning and just used Parallels Desktop to build Windows and Linux virtual machines. If things ultimately don't work out, you might want to try going that route as well. I believe Parallels offers a demo version if you want to see it in action. Regardless, I don't think that matters quite yet, because I tend to agree with b63 here. I think the biggest problem you have right now is a dead battery.
I've never had a dead battery, so I can't comment directly, but take a look at this thread, starting at post #226...
http://forum.xda-developers.com/showthread.php?t=1392693&page=23
There some back and forth for a couple of pages, but that user describes symptoms that sound very much like what you are seeing right now. I think you should try the wall charger first. Plug it in, force the Kindle Fire to turn off and just try to let it charge overnight or something. If you cannot get your KF charged with the stock wall charger, you might want to buy a factory cable. From what I gather, that user reported that his Kindle Fire booted into fastboot mode by using the factory cable even with a (nearly) dead battery. He was then able to flash the stock software, which is able to handle the dead battery situation better than some alternative ROM and have it go through the charge cycle.

Wow... so simple...

This was the deal. When plugged in with the usb cord it didn't seem to be giving it power and being powerless could not be recognized by the computer. Plugged it into the wall charger and Voila! was able to start up just fine, still rooted via the kindlewater method, capable of being booted normally or booted into CWM recovery. Awesome!
I also did a quick double-check, and now that it's powered-up, running a terminal and typing "adb devices" actually returns a list with the kindle (serial number?) on it.

I read through everything and the version of kfu that was modded for mac was 0.9.2 which I mentioned in my original post. Sounds like since I was on 6.2.2 that mac version is definitely not going to help me (both kfu out of date and stock version out of date on zergrush) if I were to want it for rooting purposes.

Thank you for your guide. I thought it was extremely well written and very helpful. It definitely helped me relax a little stress-wise while looking for a solution.
That was it (dead battery). I did try meddling around a bit with virtualbox virtual machines: a windows 7 ultimate, and a linux box that I have that does not have internet access making doing anything realtime while reading suggestions just isnt easy/feasible right now. I found that the virtualbox vms did not have access to the usb devices (flash drives, external hard drives, ostensibly if it were visible to the computer the kindle) despite my installing some optional extension packs for that purpose. I didn't explore the vms further to linux or xp simply because of the time required to install and configure a vm. I also didn't rewire my home so net access went to the linux box for the same reason... ultimately both are possible but both more hassle than it seems to be worth before simply asking the question, can it be done on a mac?

Similar issue
My KF is seeming to have a similar but distinctly different issue as the OP. Because I can turn on the KF without it being plugged in, I cannot imagine that it is a battery issue.
When I plug it in to a Windows machine, the FFF bootloader comes on, the KF seems to connect, be recognized, fail at driver installation (which I have done manually, with no success), and then disconnect. This prevents me from running any sort of commands.
When I connect to my Mac, I get the FFF bootloader and then no response whatsoever.
Trying to run commands from Terminal or the Command line or using KFU on my Windows machine all result in a "waiting for device" message.
Not sure what I should do from this point to get it back to accepting adb commands. I'm confident that once I do I'll be able to save it, but at this point I'm stuck.
Any ideas?

waiting for device

Hi fellas Great site here i have been doing a ton of reading and have create live ubuntu usb stick for this post >http://forum.xda-developers.com/showthread.php?t=1430038 very helpful by the way and I have kind fire kit on it also and I am familiar with the usb shorting trick. my problem is this ai run the ommand from terminal following directions to the "t" starts out waiting for ompad device because these kindles i have are fubared so I believe they need to be put in to usb boot mode ( they show uo in windows only as a omap44 divice and keep looping. so I run the command it lets say usb-fixinstall-fff-twrp short pin plug cable in to kindle it starts waiting for omap device starting second stage waiting for second stage sending image to target loading twrp through fast boot...,<waiting for device> this tells me I am getting it in to usb boot but thats it all comads I use are the ones with usb boot mode because I know I need it but they hang waiting for device after usb boot and by the way no green light with battery or with out battery pluged in and also nothin on screen and I keep the usb mode shorted the whole time I use a micro aligator jumper clippied to ground and hooked to a dental pick for ease of operation. it has to be a permmision problen with fastboot because I have tried 4 kindles all with the same results and by the way it also hangs on cant load twrp-blaze-2.0.0rc0.img says can't load it any help would be appreciated thank your for reading my post!:silly:

[Q] Kindle 1st gen working BUT "Unknown Device" in Device Manager

Hi all.
I have seen this in another kind of devices but haven't found thread related about Kindle Fire (1st gen).
A little introduction:
- My kindle was in CM10 and I noticed it started to be detected as Unknown Device in Windows, so
- I used TWRP to flash 6.3.1 stock ROM BUT forgot to wipe before flashing and rebooting. In that moment my situation was an endless loop wih the Kindle being rebooted after 15 seconds aproximately.
- I modified a cable to make it "factory cable" but even in fastboot (plain kindle fire logo) the Unknown Device was there.
- After many tries I managed to make a Reset to factory defaults in Android in the 15 seconds
- Currently the kindle is in stock ROM but still is not correctly detected.
Of course, I have re-installed the drivers in my computer and even tried in a fresh windows installation with no previous drivers without luck. Also, booted an Ubuntu USB with SoupKit and no lsusb changes after plugin the device (just a few dmesg messages about being unable to enumerate USB device on port).
So, if some of you have any idea to try, please tell me. I have the factory cable and the back cover of the kindle removed... ready for anything!
Thank you for your time!

From what I've seen, this is usually a problem with the bootloader. How or why, I don't know. That being said, Firekit w/shorting trick seems to be the most successful at resolving this issue.

I'm trying to follow this thread http://forum.xda-developers.com/showthread.php?t=1636883 but I don't know how to check if the "short trick" is well performed or not. Is there anything I should notice? At this moment if I make the short trick and plug in the usb connector, nothing seems to be working in the kindle but dmesg is continuously showing errors like previous ones.
Regards,

Are you using Firekit? What command?
"That's a special kind of stupid. The kind that makes me laugh"

I'm still in the step of the process when I make the short trick, plug the usb and the kindle should be detected. Should I try the usbboot commands even when there's no kindle entry in lsusb output?

YES absolutely! And hold the power button for 15 seconds to make sure the CPU isn't running before attempting the short.

The command is ./usbboot aboot.bin u-boot.bin; ./fastboot boot twrp-blaze-2.0.0RC0.img but it keeps stopped in waiting for OMAP44xx device....
I'm going to try a few times more. Thank you!
BTW, what are the next steps? Because this unit is working properly but the USB port to transfer data between computer and device: it boots, it loads stock firmware, and works properly.

Are you using a 32bit or 64bit machine? If you have SoupKit installed, option 2 should have installed 32bit libs, but sometimes it fails...mostly due to Ubuntu servers and them trying to make 32bit libs obsolete. If you're running a 64bit machine, try installing 32bit libs again and see if you get any errors.
Code:
sudo apt-get install ia32-libs
Also since you have SoupKit installed, run it and select option 4 to launch the Firekit. There's really no difference in using Firekit and manually entering the commands for Rekindle but it makes things a little easier. Select "usb_install_fff_twrp". The important thing to know about the "usb_fix_parts..." and "usb_install..." commands in Firekit is that they both use "fastboot boot ..." instead of "fastboot flash ..." to install TWRP and FFF. Meaning, if you reboot or shut the device down before actually installing a bootloader, the device won't turn back on and you'll have to do the shorting trick again.
That being said, from the moment you make the short, you only have about 2 seconds to plug the device in and have Linux detect it before the CPU resets and you have to start all over again.
Hold the power button for 10-15 seconds to make sure the CPU is off before attempting the short.
Launch Firekit and select "usb_install_fff_twrp". When the command is run, you will get the "Waiting for OMAP4 device..." prompt. Let it wait.
To do the shorting trick...
Something I have found to be most useful in this situation is to use a sharp pair of tweezers or safety pin to make the short.
Keep the device flat on a desk or table with the USB connection pointed away from you. Use one hand to hold the short, one hand to plug the device in, and use your body against the other end of the device as leverage as you plug it in.
Using a safety pin, stick the sharp end of the safety pin into the short point and press it in a little to keep it from sliding off when you plug the device in. Squeeze the other end of the safety pin or tweezers to make contact with the metal frame and immediately plug the device in while holding the short.
If the tweezers slip or make contact with the frame before you are ready, hold the power button for 10-15 seconds to make sure the device is completely shut down and try again.
You should see something going on in the terminal to let you know it's working...let it finish.
It might take a few attempts to get the timing right but persistence (and practice) is key...don't give up.
Follow these instructions and I'm positive you'll get it working again. Good luck.

OK, it's a matter of time and try it.
My computer is 64bit, but I am booting a LiveUSB with Ubuntu 12.10 32bits, so no problem around it.
About the short, one friend of mine solded a thin wire in the point in the board and I only have to connect the other side to the wire to the frame each time, so it also seems to be fine. http://forum.xda-developers.com/attachment.php?attachmentid=1045562&d=1336355873
My main concern: once I manage to make properly the short trick and the process goes forward, what will be the next step? What should I expect of this usb_install_fff_twrp command? Will it fix the hardware detection problem automatically?
Thank you again for all your help, I know you answer a lot this kind of questions and your help is very valuable.

When the OMAP4 device is detected, you will see something similar to this in the terminal:
http://forum.xda-developers.com/attachment.php?attachmentid=1262650&d=1345043823
That will temporarily install the bootloader, which is likely the cause of Linux not being able to detect it in the first place. When you see the yellow triangle on your Kindle, you'll know the Firekit worked. But you still have to permanently install the bootloader via fastboot (or TWRP if accessible) before you reboot the device.
Will it work to get Linux to detect it? Most likely, but there's no way to know for sure until you get a new bootloader installed.
On second thought...
I just realized you may not even have to do that in the first place. Lucky you? If your device is working properly as you said, boot into Android and open up the Terminal Emulator. Make sure the u-boot.bin is on your sdcard and enter the following:
Code:
su
dd if=/sdcard/u-boot.bin of=/dev/block/mmcblk0p2
reboot
See if that works.

Yes, working with stock ROM but without root access. If there's any way of rooting it without connecting it to the computer I can do it and then use dd to override the block device.

[Q] KF2 Empty and not recognized on windows

So I was trying to change my son's Fire 2 over to the new Kit Kat OS, and as I was downloading the necessary files to my computer, I thought I would wipe everything, since he had managed to pretty much fill it with junk, (he's 8). I have TWRP, (2.3.3.0) installed, and used that to wipe everything, including the internal storage and the format data wipe. I have done this with my Fire 1 with no issues, but this time I ran into a problem. TWRP works fine, but now windows won't recognize the tablet. When I go to mount the usb storage to copy the os files over, windows 7 cant load the device drives, and in my device manager it shows the Amazon Kindle fire 2 with the yellow exclamation mark next to it, saying that the drivers for this device are not installed. I have the SDK installed, and I have gone through and re installed the device drivers several times, and also uninstalled the kindle from the device list in manager. Nothing is working. I have attempted fastboot, but when I do try, it gets stuck at the "press the button menu" for TWRP, and after running the fastboot -i 0x1949 getvar product command, it tells me it sees an Otter2-Prod-04.
Does anybody have any ideas or suggestions on how I can get into the usb storage so I can load the OS info? Thanks for any help.

Dead?
Well, I rebooted from TWRP and it just went black. No light when the cable is plugged in, (factory cable), no twenty second reset working, nothing. IS it safe to assume I now have a pretty paperweight, and I should be looking into getting my son another tablet?

Leave it on the charger overnight. Keep trying 20 second reboot. If you can get back into recovery you can adb sideload a rom into the device.
You've never been able to USB Mount this device from recovery.
Good luck. No reason it should be bricked....
How did you try to get into fast boot? You need a fastboot cable. This device is NOTHING LIKE the kf1.
Edit: also need to be sure exactly which kf2 you have.

Leave it on the charger overnight. Keep trying 20 second reboot. If you can get back into recovery you can adb sideload a rom into the device.
You've never been able to USB Mount this device from recovery.
Good luck. No reason it should be bricked....
How did you try to get into fast boot? You need a fastboot cable. This device is NOTHING LIKE the kf1.
Edit: also need to be sure exactly which kf2 you have.

I have the standard cheap Kf2, no HD, just the upgrade from the first from last year, (2012), they were selling around Christmas last year. I have tried getting it to start back up, but with no success. I don't even understand why it shut down like that. I hadn't done anything to it other than reboot, which I had done successfully several times before. As for the fastboot, I may be incorrect. I ran the adb command: fastboot -i 0x1949 getvar product in CMD, and then plugged the kindle in and booted up. It showed it was an otter4 or something like that, which I thought meant it was in fastboot. At that time I was using my S4 usb cable. I'm sure I can sort out ho to sideload a rom via adb if I can ever get it started back up again. I had thought about opening it up and unplugging the battery and then re-plugging it back it to try to reset it, but I doubt it will help. Would getting a fastboot cable possibly make it start back up? If anyone has any suggestions on how I can get this thing started up again I would greatly appreciate it. I fell like crap for bricking my kids kindle, he's 8, so it's really important to him. It'll take me several months to save up to buy another one, so if I can get it running again, that would be awesome.

Here's a bit of an oddity, and maybe this spells some hope for me yet. So I plug the KF2 into the computer with the factory cable, hold down the power button for twenty seconds, let go, and then hit the power button again, for about a second, and windows makes the usb device plugged in sound, followed by a usb rejected or not recognized sound. It repeats this over and over for about thirty seconds or so and then stops. So there is something going on with the kindle, and its not flat out dead, or at least it seems. Is this a good sign? Does this help anyone to figure out what I might need to do?

So just to be sure that I was using a fastboot cable, even though I believe that my samsung s4 cable is fastboot capable, and I'm pretty sure I am using the factory cable, (it's not marked so I can't be 100% sure), I built my own fastboot cable, via instructions on how to do so on xda. (found HERE) It's doing the same thing with windows making the usb device inserted / recognized sound, followed by the usb device error sound. I'm guessing that this is a bad thing, am I correct?

One more bit of information to add to the list. I attempted to do the fastboot mode again,and decided to watch my device manager. Whenever windows chimes off that it detects a usb device, something called OMAP 4430 pops up for about a second before disappearing when the error sound comes on. I'm going to try and get a driver for that, just to see what happens. Maybe it'll help. I doubt it, but you never know until you try...

This just keeps getting weirder and weirder. So I installed the omap driver for windows and android, and now windows recognizes the device, but only for about a second. It just keeps cycling through the usb connected sound, recognizing the omap device, and then the usb disconnected sound, as though the device were being plugged in and then unplugged about every second for roughly thirty seconds. I'm starting to think there is something seriously wrong, which bites. If anyone has any suggestions, I'm all ears.

That's a hard brick' we can't use the usboot/aboot utility to fix the device like you can on other omap devices because we need a certain signed file to fix the boot loader. Only amazon has that file and they aren't giving it out. There is a way to recover your device from a hard brick but you need to be good with a soldering iron and have a USB sdcard reader, the kind that kinda is like a flashdrive rather than the multi type readers and some really small wire. Kurohyou wrote a tutorial on how to fix it in the kf2 dev section, not sure if he ever added the part in on how to reflash the boot loader from Linux, but if you take this route and try to fix it I wouldn't mind helping.

OK, I have both a tf - micro sd card usb card reader, and a full sd card usb card reader. I'll have to go digging for them in the morning, but I think I can find them. I'm also really good with a soldering iron, (used to be a vcr / tv repair technician), It took me roughly two minutes to do the homemade factory cable. So I am game, especially since at this point I really have nothing to loose by trying. Would you mind posting a link to where the tutorial is? I'm going to go looking for it, but just in case I can't find it, a link would help. And thank you so much for this suggestion!

OK, I found the tutorial on how to wire everything up and what's needed. I'll have to go get some small wire and a better tip for my iron, but aside form that, the wiring and soldering seems simple enough. My problem is going to be dealing with linux. I know Windows backwards and forwards, but I have a pretty limited knowledge of linux, aside from a few things we did in school to cover general PC repair. I can get it up an running, which I will do tomorrow, but I may need some help sorting out what to do with it once I have the board lined up and ready to roll, which will have to wait till next week when I get back from a work trip. Do you know if kurohyou offers repairs? If it's not too expensive, I would be willing to pay for the fix.

He might repair it, he just made a solderless repair tool to repair them. But like I said I'm more than willing to help with the Linux side, I'm a PC tech myself and use Linux primarily, you can basically burn an ubuntu live CD or put it on a USB stick and boot into the entire os without having to install it, from there's its as simple as plugging the device into the PC, and seeing what device path it assigned to the kindle's emmc, and running a dd command to flash the boot loader back onto the device.

Yeah, I've ran a live usb version of unbuntu a few times, and in the past I have had the full version on my system, but I rarely ever used it, so I got rid of it. I have an extra 600 gig's of space just sitting around on my laptop, so I will install a full version, and get off my lazy rear and start learning linux. This should be a good first lesson. I can't do any of this until next week though, so I will be pm'ing you once I've gotten everythig hooked up and ready to go. Thanks again for the help.
I had a question about the repair though. I went through the discussion, and I may have just missed it, but did he ever figure out how to get the OS up and running? From what I could tell, he was still working on it, and hadn't managed to get a working rom loaded. I probably just either missed it, or didn't understand one of the post's.

Ubuntu 14.04 debug mode issues

So I found a few mentions of this throughout the forums, but nothing that came really remotely close to solving the problem.
I'm having trouble getting my machines (a laptop and a desktop) running Ubuntu to recognize my device (LG G4) - but not always. So naturally, I tried to set it to PTP mode, but I actually couldn't find this setting anywhere on the device. I plugged it in on my Windows machine and made sure it was in PTP mode while plugged in, and still no luck. This is pretty problematic seeing as I'm a developer and I'm going to be starting work on an Android app for work soon. I'm not 100% sure if this is a problem centralized to the G4, but I didn't really get any reception on the Ubuntu forums, so I thought I would check here. Has anyone else had this problem?

No problems here, though I am using 15.10.
It does take a few moments, though. Once the phone is plugged in, I get the 'USB Connected' notification. which is where you can tap to change from mtp to ptp. After a few moments, it will automatically go to mtp/ptp mode - whichever was the last mode you set. Then a few moments later the debugging notification comes up, and I am then able to see the phone in adb.

Have you tried this?
Find the vendorid and productid with lsub:
$> lsusb
Bus 001 Device 013: ID 0bb4:0c02 HTC (High Tech Computer Corp.) Dream / ADP1 / G1 / Magic / Tattoo (Debug)
...
the "0bb4" is the vendor-id, the "0c02"is the productid
open the file "/lib/udev/rules.d/69-libmtp.rules" for edit:
$> gksudo gedit /lib/udev/rules.d/69-libmtp.rules
Insert the new device, by duplicating a previous one and correcting the id's and save the file:
# Wiko DARKMOON
ATTR{idVendor}=="0bb4", ATTR{idProduct}=="0c02", SYMLINK+="libmtp-%k", MODE="660", GROUP="audio", ENV{ID_MTP_DEVICE}="1", ENV{ID_MEDIA_PLAYER}="1"
Unplug your smartphone and replug it. Your Linux should mount your device like it would do for other one.

I got these directions from http://stackoverflow.com/questions/15055304/unable-to-mount-samsung-android-in-ubuntu and it helped me get my phone properly recognized in Mint.

I'll give this a shot.
And thanks, but no amount of waiting brings it to debug mode if that's not in the cards. I just plugged it in, and on the first try it went into debug mode, but on subsequent plug-ins, it failed to recognize. Really odd behavior. I was beginning to think it a factory defect, but my buddy's phone also doesn't work, so it definitely seems to be Ubuntu.
Unfortunately, no luck on this. Adding device rules to either this file or 51-android don't work. I also find it incredibly strange that it is recognizing it ~1% of the time.
Just as clarification, I've made positive my maufacturer and device ids are correct. I managed to lsusb on one of the successful plugins and used those details to fill in entries in the rules files.

When I get home I'll fire up an Ubuntu distro and see if I have the same problem. When you plug the phone in and type "ls usb" does it show at all there?

Thanks!
Only when I get the verifications that come with a successful attempt. A beep-boop, an android bug icon and usb icon at the top of the device, and a popup about my file-system. I ought to have copied the lsusb output here, because of course I can't get it to recognize now.

I have Ubuntu 15.10 but it works fine with that. As soon as I plug my phone in, I get instant notification that its recognized on the phone, and then a few seconds later it mounts in Ubuntu. At this point it sounds like either a hardware problem like a bad USB cord, or some sort of corruption in your Distro. Have you considered running another Ubuntu distro off a LIveUSB to rule out the hardware?

Since you need to be in ptp mode, editing a udev rule for mtp recognition is not likely going to help, I think.
I would definitely check your cable, and even usb ports used. I just booted my 14.04 laptop, and it works exactly the same as in my 15.10 laptop and PC

Yeah, I think I'm at the point where I've tried a different phone, different cable, different port, different computer, and the only thing that worked - different OS. My home desktop deploys test apps just fine, but I used the same Ubuntu Gnome 14.04 image for my other two computers.
I should try re-installing the drivers I guess.
