Hi guys,
I tried to unlock the bootloader of my Nexus 10 before rooting it. Unfortunately, it didn't work and I can't use it anymore (I either have the "Loading X" forever or a dead droid while trying to go to the recovery mode).
I'm used to do that kind of modifications (only on Samsung Galaxy S and S3 though) and I don't know what I did wrong (but I usually flashed with Odin).
Anyway, I used this tool (after enabling the usb debug and allowing unknown sources) : http://forum.xda-developers.com/showthread.php?t=2001868
I installed the drivers on my PC (menu 1 in the tool), then I could see my device in ADB MODE (in the tool menu). I tried to unlock the bootloader (3rd option in the menu) and it was written completed. My device reboots and nothing happens. I can access the fastboot mode (is it the download mode ?).
I have Odin.
Can someone help me to get a working device ?
Thank you very much.

Easy fix. Get to the dead droid recovery menu and then press all 3 buttons on the top. You will get into the blue recovery options. Choose factory reset.
Sometimes unlocking the bootloaders scrambles a few things on this device and it goes into boot loop. After the factory reset, you'll be fine. PM me if you still have issues.

Okay, thank you very much. I didn't know I had to press the 3 top buttons again after the dead droid screen, I thought it failed loading the Recovery Mode.
I have to setup my account etc again so I guess it is safe to say it worked.
Additionally, I tried this method after the recovery : http://forum.xda-developers.com/showthread.php?t=2015467
and it worked fine. My device has an unlocked bootloader and is rooted.
hey if someone could help me im stuck myself, after i had the dead android in recovery mode i tried to flash software with the toolkit in fastboot and now when i go to recovery its just a blank screen till i hold the bottom combo again and it takes me back to fastboot

Hey,
I'm having the same problem. I get to the dead droid instead of recovery and tried hitting all three buttons again but it's just looping again.
Any ideas?

It sounds like you didn't actually perform a factory reset. The key combination to get into stock recovery from the dead android screen is Power + Vol-Up. That will bring up the option to factory reset.
So if your powered off or bootlooping, hold the Power + Vol-Up + Vol-Down until you're back in the Bootloader. Use Vol buttons to select Recovery Mode and tap Power. When the droid w/ the Red "!" appears, hold the Power button and quick press the Vol-Up button. This should take you into stock recovery. Select Factory reset. Reboot. After a few minutes, the device should boot normally.
Good luck.

Ok found a video showing that when you get to that part where there's the dead droid (the red !), you don't press hold hold all three buttons but tap them until the recovery screen shows up.
So finally did that but I still have the same problem.
My initial problem was, I received my N10, open the box, turned it on and it started freezing and rebooting. Can't get past the wifi step.
Tried hard and many times to finally get to enter my gmail account, etc
Updated to 4.3, problem persisted so I figured, maybe the factory flashed a bad rom?
So I unlocked it, rooted it and tried flashing older stock versions, same problem.
Tried flashing CM, same; PA, same...
Tried deactivating location service as suggested elsewhere: same; uninstall chrome: same
Even CM withouf GAPPS wouldnt work
So basically, I have a $500 brick. Completely useless as it freezes every 30 seconds.
Decided not to return the device because although I am Canadian, I live in SE Asia and had a visiting friend bring it to me. Way past the return period and the overall experience would be a real pain in the butt... Don't know what to do. Really hoping Kit Kat will solve it but I have doubts.
What do you think?
Sorry. I don't know enough about these things to give more in depth troubleshooting advice. I just recently got my N10 & unlocked it and based on your original post, I thought that's where you needed help. But it sounds like you got past that and got it unlocked.
Have you tried downloading a factory image directly from Google and installing that? If it's locking up on a fresh install of any ROM, it very well may be a hardware issue. You may have to file a warranty claim if possible.

Hi there,
I juste got a cheapo Azpen A729 tablet. I succesfully rooted it with Kingo Root and it was also recognized by ADB. I then tried to boot into bootloader through ADB, but it never when past the Azpen logo screen and since then the tablet is stuck at the that screen whenever I try to restart it. So I'm afraid that I bricked it... On the Azpen website there are firmwares for several of their devices, but not for the A729. Does anyone have experience with this device and maybe some advice? Thanks!

yes you bricked your device.
you rooted that device, but not unlock dootloader.
Hi,
I just tried to boot into bootloader, not to unlock it or anything else. I simply rooted the device, I didn't try to install any custom recovery (not that there would be one anyway, AFAIK) or anything like that. If I'm missing something here, would you mind to explain? Thanks.

Ok, I understand
This device have stock recovery???
Yes, everything is stock, the only thing I did was rooting it with Kingo Root, like so: http://forum.xda-developers.com/android/help/root-azpen-a729-t3003908
Unfortunately there isn't much information out there yet for the A729, it seems to be fairly recent. Treecheetahdolo here managed to unbrick his A727, but unfortunately there is no firmware (yet?) available for the A729 on azpens site to try this...

Go to recovery and wipe data and cache.
I'd like to, but I'm not able to go into recovery unfortunately... It's supposed to be vol-down + power button (http://www.azpenpc.com/service/detail.php/id-9.html), at least for the earlier devices, but this doesn't seem to work here, it always gets to the Azpen logo screen and gets stuck there... I tried every other key combination I could think of, but to no avail. Either the device is seriously bricked, or there's a secret key combination here to go into recovery that azpen didn't communicate...

The [Vol- ] [POWER] combo works, but you have to hold them until the unit powers on, (like forever). If it won't go past the Azpen LOGO, I would recommend contacting your local supplier.
Ok, so if, when you boot into recovery, it still passes through the Azpen logo, then there might definitely be a problem... :-/ Mrdownboy, you have a A729, right? Did you already boot into the bootloader at some point? This thing does have a bootloader, right? I contacted Azpen to see if they have a firmware image that I could try to flash, before trying to going through a RMA procedure with my rooted tablet... We'll see. Anyway, thanks!

Hey maksmtl,
I haven't tried accesing the bootloader yet, I'm still on the process of acquiring another brand new A729 for dumping the ROM and then start from there. I'll call Azpen tomorrow and ask them about a stock fw, but I wouldn't hold my breath. Once I have a stock ROM, I'll start looking into a custom recovery. Baby steps...

I don't quite understand what you are saying here... You have to hold [Vol-] [POWER] until the unit powers on, (forever...). Then just sit back and relax. If after 15 mins you're not on recovery, and it's boot-looping, it might need a STOCK ROM re-flash.
Hi mrdownboy,
what I meant is that, I thought that, as with e.g. a Nexus device, when you boot into recovery it directly goes there, without going through the google logo screen first as it would in a normal boot. So I thought/was hoping, that on the Azpen it would do the same thing, not going through the logo screen when booting into recovery. That's why I thought that I didn't have the right key combination, because it would always boot into the azpen logo screen, where it then gets stuck. From what you said, I understood that the azpen still goes through the logo screen first, before going into the recovery menu, or did I misunderstand you here? When I press and hold [Vol-] + [POWER], the device boots directly into the azpen logo screen after 8 seconds or so, after that nothing happens anymore. I also tried to keep holding the buttons after the logo appears, but that doesn't seem to change anything neither, unless you really have to do that for an insanely long time...?

Nope... But again, just to be sure, since I'm still a bit confused here: when you go into recovery it DOES go through the Azpen logo screen first, right?
I wrote to Azpen as well about a firmware for the A729, since they have firmwares for other models, but I didn't get a response yet. But then again, if if I had a firmware, I'm not even sure if I could flash it with PhoenixUSBPro tool, if the device can't go into recovery, I doubt it can go into download mode... Btw, be careful in your development if you don't want the same thing happening to you when booting into the bootloader... It would be definitely cool to have a custom recovery and eventually cutom ROMS however!
If I can't recover my device I don't even know if I'll try going through a RMA though, since it might be too expensive sending the tablet in, considering its initial cost...

If you call them right now, you'll be surprised how good they are at personal customer service. They WILL offer options, but they don't have the firmware available for public release yet. Is your model the A729BT or the A729 Non-BT? I really want to do a ROM dump, but it's proven way more difficult than I initially thought. If there is a way to dump a ROM w/o rooting it would be excellent.
Also, I don't think they have a bootloader installed.

That's what they show on their website, but it has not worked for me at all. I've tried repeatedly with vol+ & power, vol- & power, vol+ & vol- & power... nothing has worked, it always boots fully up.
Is yours the A729 with bluetooth from TigerDirect? (their website lists that only the TigerDirect version has Bluetooth)
Were you actually able to get into the stock recovery menu?

I called them and I definitely did not find them customer-friendly.
I politely pointed out that the Users menu was missing and as I understand it, it's only an entry in a config file to enable it and asked if it would be possible to get a patch as I bought this for my son and didn't want to have to root it and the guy on the phone cut me off mid-sentence and scolded me for even mentioning rooting the device and told me it'd void my warranty. I asked about the firmware image and he was very dismissive about it. I asked if I could submit a bug report about the fact that a valuable feature of JB 4.2+ was missing (and the fact that this was a tablet that appeared to have a phone build of Android, more below). I'm not even sure how to describe his response "you want to submit a BUG REPORT?!"... yes, I do. He gruffly agreed to take down my request and proceeded to ask me for full contact info (full name, address, email, phone number, etc.). When I asked for the case number, he was confused... they apparently have no bug or complaint tracking system whatsoever. He explained to me that there was no way the developers were going to provide a patch, that Android is open source and it's up to the developers to decide how to configure the builds, etc. After some back and forth, I finally asked him how big the company was. He was obviously taken aback, so I explained that he seemed to know an awful lot about what the developers would be willing to do... he took this as a compliment and explained that I had "called corporate" (I called the support number on their website).
This screams "tiny operation" to me... either this guy was one of the developers (answering the customer support line), one of the main people in the company, or they're simply an importer and order the devices in bulk and resell them with nothing more than a custom logo.
Alibaba lists this unit for "US $1 - 45"... minimum qty 100 units.
More on the build: This device appears to have a default config for a phone, as not only is the Users menu missing, but it has a "Mobile network settings" menu which is entirely non-applicable to a device like this (menu items include "Data roaming", "Preferred network type" (2G/3G), "Network operators", etc.).
I sure hope I caught him on a bad day, and others have better luck.
Oh - and the reason I was reluctant to root it right away was I'm a bit gunshy and wanted to make sure I could return it if I needed to. I recently had a horrid experience with a d2 tablet that bricked itself (black-screen before splash-screen) after a few hours of use on Christmas morning (nearly every review on newegg for the device, all posted after I bought it, had the exact same problem). I'm lucky I was able to send that one back for a refund. Thankfully, this one appears to be a *lot* more reliable a unit (my son has played many, many hours of games on it for the past month).
I talked to the Azpen support, and they told me to push the volume button in the middle (I guess that comes down to the same as pressing vol- and vol+) and the power button. In my case that didn't work, but my tablet seems to be definitely bricked... I have the BT model from TigerDirect.

I just tried it again by pressing in the middle (in case there was a 3rd switch) and could feel both the up and down button click, and it booted all the way up (the logo came and went 3 times as it was booting up). I held all three (incl power) buttons down until it had the full Android display up (with the lock slider).
So... sounds like the guy was wrong - even on a fully functional unit, that won't bring up the menu.
It does have a recessed reset button (you can only hit it with a paper-clip or similar). I've seen some devices where you have to hold that down for ridiculous periods of time. I'm surprised the guy didn't mention that.

Please don't panic. I've found myself in the same situation with my A729 where key press sequences and back panel reset were to no avail. As a matter of fact, just last night I found myself where you are now. After booting into the bootloader through ADB, my Azpen had that same zomie stare that your's is experiencing.
Here's what I did. I turned it over screen down and walked away. Simply let the battery deplete over night. When you attempt to turn it on tomorrow it will complain of insufficient power. Plug it into your charger for about a half-hour, press and hold down the Volume "UP" button and then press the power button (You've heard this drill before, but THIS time you've given the instrument time to "forget" the last instruction given to it.) Let me know if this time (finally) your Azpen A729 boots into the recovery screen.
Most importantly, don't panic. Let the battery deplete firstly and then attempt the recovery mode.

Hi PoFolk,
that sounds very promising! My Azpen is draining its battery right now. I actually had a suspicion that the tablet wasn't completely shut off, since every time I plugged in the charger, it would boot into the Azpen screen right away... But I didn't think about letting the battery die to give it a fresh start. Crossing fingers right now...
Oh, and I'm not panicking actually, I was almost expecting some problems with such a cheap tablet. I would probably be panicking more if this was my Nexus 7, which I just gave a new youth through F2FS.
Anyway, I'll let you know how it went tomorrow, thanks! Btw, are you sure about Volume "UP"? That would be new.

Works for me:
1) Depress "UP" volume button throughout this procedure.
2) Depress power button and release when Azpen bootloader logo appears.
3) Sing or hum a tune whilst the Azpen logo stares at you, all whilst you're depressing the volume "UP" button. (yes, it seems like an eternity)
4) Android system recovery screen pops up.
5) Don't try anything fancy just yet. Select "reboot system now".
6) Light up a cigar or draw a beer. Your Azpen should be restored.

Try long pressing (20 sec) the power button. Not a solution but may provide additional information that could aid in further recovery. Also try power & volume up button (+) together as suggested by EncryptedCurse in the other forum. Release the power button immediately but keep volume up depressed until there is a response.
Also try keeeping the power button pressed for about 2 minutes (count them) and see if that works.
My Kindle fire HDX 7 i think bricked any solution?
I was trying to root my Kindle fire HDX 7 for android apps and google apps on it. it was successfully rooted and google play services working on it perfectly. Than suddenly google play stop working on it. but games installed on it working properly. Then i go to recovery option and press the Wipe button "Cache and Dalvik Cache". after that my Kindle fire HDX 7 boot and stuck on Kindle fire starting Grey logo. I tried to factory reset but still keep stuck on start logo. While connected to PC, only hear one connectivity beep with PC and in device manager only shows connectivity as MTP USB device. But no device show in my computer. Snapshot attached. Please assist any solution.

I have a Kindle Fire HDX 7" (Thor), yesterday I was trying to flash an Android ROM on it. I got up to the point where I was in TWRP, and I accidentally factory reset the Kindle thru TWRP. When the Kindle rebooted, it showed a screen that said something like...
"Kindle Fire System Recovery; Your Kindle doesn't seem to be able to boot. Resetting your device to Factory defaults may help you to fix this issue."
The choices it gave me were, "Reboot your Kindle" and "Reset to Factory Defaults"
I rebooted my Kindle as a first choice, and it booted back to the same screen. So then I reset to factory defaults. Nothing worked and it kept bringing me back to that screen. I'm guessing there is no bootloader or anything on the Kindle.
I left the Kindle on for hours as I was trying to find my fastboot cable knowing that I would probably need it to fix this problem. I then turned off the Kindle hours later (press and hold until screen shut off). I did have a full battery prior to trying to put an Android ROM on the Kindle.
This morning I found my fastboot cable, but when I pressed the power button on the Kindle, it will not turn on. No response from it at all. Did I drain the battery?
When I plug my Kindle to my computer using the fastboot cable, it was showing me "QHSUSB_BULK" in the USB device list. I tried ADB, but it says "error: device not found".
When I plug my Kindle to charge, it doesn't show the low battery/charging indicator like it used to.
What should I do next? Is my Kindle permanently bricked?
I need mad help right now!
Try to boot into twrp, but you may bricked your device permanently because you did a factory reset with the default kindle recovery

Okay, one question, how would I boot into TWRP? I ask only because the Kindle is not starting up, and when I plug the fastboot cable, the computer is not recognizing it.

By TWRP you mean safestrap recovery? If you flashed through safestrap other ROM than Nexus for Safestrap 1.0.1 (which one BTW? Did you flash by accident ROM for Hdx 8.9?) that could be the first reason for bricking your kindle... Safestrap is not TWRP, is only TWRP based and works differently than TWRP 2.8.5.0, also safestrap is located on system partition, but TWRP 2.8.5.0 when installed is flashed to recovery partition...
Doing factory reset through safestrap should be relatively safe unless you mess with advanced wipe and delete/wipe system partition - this effectively erase content of /system including safestrap recovery, this could be the second reason for bricking your kindle.
If you had installed real cuber signed TWRP 2.8.x.x, then the only thing I can think of is that you tried to flash one of amazon update bins with TWRP, these bins when installed replace content of the recovery partition with Amazon FireOS recovery, successfully deleting real TWRP in the process, but this should end with booting to FireOS...

Just hold the volume up button (+) when it's booting.
However, I'm not really sure of your situation, because TWRP should've replaced the stock recovery.
I finally got it to turn on somehow. And this is the screen that it's giving me (see attachment). I tried both of the options given and it'll bring me back to the same screen.
Also, before I was able to power on the Kindle, it'll say QHSUSB BULK in the connected usb devices when I use my fast-food cable on it. But when I have the Kindle powered on it says Unknown Device.
If I can get the Kindle to respond to adb I can probably work from there. But my computer is not recognizing it.
What version of fireos you had? maybe is possible to unlock bootloader.. but you should know mmc manfid and serial. We don't know yet how to get emmc serial from bootloader only.

I had to rollback as I was following the guide on the post in the developmental forum on here. Will the manufacturer id be on the box? I still have the original box for the Kindle.

Actually you can get it from adb without root
My Kindle is not communicating with adb. I've been trying all week and doing a lot of researching. I either get an "Unknown Device" or "QHSUSB BULK" in the connected usb list.

Dies it go in fastboot mode with vol+ vol- power?

I held the power button for maybe a good 30 seconds and it powered on and took me to that screen. I'd usually have to keep trying to get the Kindle to power on, and when I do, that screen is all it'll do.
Turn kindle off.. then press and keep pressed vol+ and vol- and keep them pressed. Turn on kindle while pressing both volume. You should enter into fastboot. If we found a relation between emmc serial and kindle serial number you should be able to fix it. (I think your boot.img is corrupted)

I was able to get back to that screen by following the steps in this quoted post.
My Kindle gets the same status. It was safestraped, locked on 3.2.8. Tried to update it with OTA to 4.1.1, it downloaded firmware, checked and rebooted, after that device won't boot up and on connect to pc detects as QHSUSB_BULK. The only way i found is to ask replacement at support

(reposting as a warning to those who may stumble across this thread)
This seems to be the recent fate for many who have rolled back to 3.2.8 and not blocked OTA using HDX Toolkit or an equivalent blocker (renaming otacerts is not reliable). It appears Amazon attempts to push an update that ultimately corrupts the boot partition. Not much you can do to fix it with current techniques/exploits.
If the device is still under warranty Amazon will likely replace it. Just say it died during an update.
Help! I have a newer HDX 7 that is stuck trying to reboot. The device powers up to the gray kindle fire screen but sits there for a minute or so and then the screen flashes and it starts all over. The device does not recognize the power button. I've tried the hold the button for 40 seconds to reset but it just keeps going through this loop while holding the power button. When I connected it to my PC (Win7), it does not see the device. If I connect another Andriod device, it sees it imeadiately.
I'm a complete noob with this but I'm actually in IT, just not in this area. This is my sons device so I'm not sure exactly what he was doing at the time it started this but my guess would be playing MineCraft. Amazon's wonderful support says it just needs to be replaced but it's out of warranty. My son and I were just about to start an online coding course so I'd like to get this back up and running so we can start that. Any help would be appreciated. After searching the web, you guys seem to be the only ones able to root or fix any software/os issues with these devices.
Thanks,
Doug

Your options are limited given the device is largely invisible via tether (even then there would be little recourse as adb is probably disabled). Did you try a factory reset? Amazon's crippled recovery environment can be accessed via power + vol-up from a cold start. Release the power button after the gray Kindle logo appears. If the recovery menu comes up the only option is 'factory reset'. I realize you may not be able to access recovery given the non-responsive power button.
Any chance you son is old/savvy enough to trying rooting the device? The symptoms suggest either a failed automatic update (rare but it does happen) or botched attempt to root via the wrong method. Obviously a spontaneous hardware failure is also possible albeit unlikely.
Do you know what version of Fire OS was running just prior to the boot loop?
There is still a small chance adb may help even if the device is not recognized by Windows explorer. However, if as Davey said, it is disabled, things are limited.
Again, do you know what version is you were running?
Have you installed adb?
Have you tried recovery?

No, Unless it updated automatically, it was the same version that was on there when it was delivered around 4/14.
No, My son would not have tried rooting this on his own.
I was incorrect when I stated that the system wasn't recognizing the power button. When I try the hold the power button for 40 secs or the Power button + Vol up button to restart, the boot loop gets shorter.

I have installed ADB on my PC but it doesn't see the device (although I'm not sure I'm using it correctly). What command should I be issuing to see if the device is connected. If I use "adb devices" I get the response in the attached screen shot.
If by recovery, you mean the recovery on the device, the power+volume up button doesn't work.
I appreciate all of the help!

Given the delivery date and age of device I STRONGLY recommend you reach out to Amazon for a replacement vs trying to resolve on your own. A new version of Fire OS is currently rolling out which MAY have triggered the behavior you are seeing. Bit of a bummer given your son's course plans but a worthwhile delay IMHO.
I agree with Davey.
