Hey there.
I flashed a new ROM (Kaos Droid 7.0.0) and the fitting gapps some minutes ago from CWM Touch. Everything worked as supposed, no errors, no warnings, nothing. Then I rebooted the Nexus 7 and now it's stuck in the worst bootloop I have seen so far:
The Google Screen appears, stays for some seconds, then I see a screen with the CWM Logo and the text "ClockworkmodRecovery 6.0.38", after this the device seems to reboot and the sequence starts from the beginning again.
I can not get into recovery, I can connect to my PC via USB but connection and disconnection happens every few seconds (because of the bootloop).
I guess that's it for my Nexus 7 or does anyone have an idea what I can try to do. I'd be really thankful.

Hi, Jagutherrschaften...
Try pressing VOLUME DOWN + THE POWER ON KEY and HOLD BOTH for 30 seconds (or as long as it takes to break out of the 'bootloop').
(or BOTH VOL KEYS + POWER ON if the above doesn't work... although it should).
Keep them pressed until you boot you into the bootloader....
You should now be free to run fastboot commands, to either fastboot flash back to factory stock... or you could attempt to just boot into recovery, and maybe do a Nandroid Backup restore from your previous setup (assuming of course, you created one).
Anyway... as long as you can still access the bootloader... all is not lost.
Rgrds,
Ged.

Sorry, I forgot to mention that I can't boot into bootloader. I tried every single combination of keys. The bootloop goes on and is completely unimpressed by my keypresses. Bad bad thing.

How fast is the bootloop? and how long are you pressing the buttons for?
Lean on them, as it where, for a good minute or so... the device has to pick up the 'interrupts' sooner or later.

Thank you for your answers. I tried every combination and kept the keys pressed for 2 mins. Nothing. The only thing I can actually do is shut the device down by pressing POWER + VOL UP for a long while.
If bootloop doesnt stop and you cant get into bootloader....then just long press power button..that should stop the cycle...and then volm down plus power button....should get u into bootloader..atleast worked for me..

The normal method you described neo45215 doesn't work for me as well.

Mmm... this is a strange one...
Just had a look a your video... and I've seen a few bootoops, but never one involving a Custom Recovery and ONLY the Bootloader Unlock screen (yes, that is the Bootloader - it's just not normally recognized as such, because it's not in FASTBOOT mode).
If you've shutdown the tablet by pressing VOL UP + POWER ON, you've effectively booted the device into APX mode (it looks like it's shutdown, but it isn't) - if it is in APX mode, the device is now awaiting for you to run some nvFlash commands, which currently can't be done (though there is now, a very specific exception, which is not applicable here).
I agree with the previous poster, @neo45215, VOLUME DOWN (hold), then POWER BUTTON, (whilst still holding VOLUME DOWN), should boot you into the bootloader... but I think precise timing is required. Please read the following, carefully, several times.

QUOTE from http://forum.xda-developers.com/showthread.php?t=2133986
"Starting from booted or boot-looping OS:
Power (10-15 seconds) -> Normal OS Boot**
** Bootloader Interrupt: In any of the cases where you hold the power button down to try to break out of the current operating mode, if you press the Vol-Down button right after you first see the black and white screen with the Google logo, the tablet will proceed immediately to bootloader/fastboot mode, rather than booting the normal OS. You need to be ready though - you only get about 1 or 2 seconds to do this! (Thanks to RMXO for pointing this out) Note that this means you can get to the bootloader directly from any other mode!
This also explains why, when attempting a cold start using Vol-Down + Power, if you accidentally let go of the vol-down button when the screen first lights up, the Nexus 7 will boot to the normal OS. In this case, pressing Vol-Down initially is actually superfluous - what makes the device go into bootloader/fastboot mode is the Vol-Down press immediately following the google splash screen - there actually is no unique "Go to fastboot from a cold start" method."
----------------------------------------
I'm at loss to suggest anything more helpful... this looks like the bootloop from hell! But I'm convinced, that with the correct timing and persistence, some key-combo interrupt could break the Nexus 7 out of it.

Thanks a lot for your help, I have tried everything, I can't get anywhere... neither bootloader nor recovery.
Additionally I can't make the device do anything I want by adb.
And as a "bonus" I can't send my Nexus7 to repair because this stupid bootloop shows "ClockworkMod Recovery v6.0.3.8" :silly:

Really sorry to hear this... it is baffling:.
I've been hanging around on XDA since January, and I've come across a lot of weird behaviour, reported by other posters. But this is something that is outside my experience.
A few questions... (no guarantees, but I'll try to see if I can come up with something)...
Can you post download links for EVERYTHING you've flashed...
The ROM, the Gapps, the CWM recovery.
Also, what order did you flash them in?
Did you use fastboot? or a Toolkit at any time?
Where you rooted BEFORE you embarked on this endeavour?
How did you acquire root?
How long have you had the Nexus 7?
Is it a WiFi only model or a WiFi and 3G model?
Have you flashed any other Custom ROMs prior to this one?
If, so, any problems?
Do you know your current bootloader version number?
What was the battery status (percentage) prior to you flashing this ROM?
Sorry for all the questions... but something, some tiny litlle detail, might set a 'eureka!' light bulb off in my head.

OK, I'll try to answer as detailed as possible:
ROM KaosDroid7.0.0
FittingGApps
CWM Recovery (Touch) was installed through ROM Manager Premium
The order of what I did was: I made a backup in Titanium Backup Pro, then I made a nandroid backup by ROM Manager Premium. I went to recovery, wiped /cache and /data, then flashed KaosDroid7.0.0, flashed GApps and rebooted. After my Nexus7 had fully booted I restored some user apps and settings via Titanium Backup Pro. I had to reboot. After that I explored that clock was force closed whenever I tried to access the alarm clock. I wondered if I could possibly have overseen a checkmark when restoring with Titanium Backup Pro (maybe forgotten to untick a system app or setting) which could lead to the force close. So I decided to start over again.
This time I thought about using ROM Manager Premium for wiping and flashing. I started the app and it told me there was an update for CWM Recovery. So I installed this update through ROM Manager Premium - CWM Recovery Touch 6.0.3.8. I rebooted and went to recovery to flash ROM and GApps again the normal way. Before flashing I wiped /cache and /data again. Everything went fine until I rebooted the tablet and found myself in this "bootloop of hell" as you called it... After having tried a lot to break it, I opened the Nexus7 to remove battery for the first time.
OK, now the other questions:
I bought my Nexus7 about 11 months ago, it's the 16 GB WiFi only version. I aquired root by using this Toolkit and everything went really smooth. I tried several ROMs yes, after some time I came across KaosDroid (don't exactly know which version I started with, maybe v5.0.0) and really liked it. I flashed a new version whenever there was one and never had any problems before.
I am not sure about my current bootloader version, I have some not too long ago nandroid backups on my PC, can I find out anywhere in there? About battery, it was 55 % or so before I started flashing, maybe even more.
The way I see this is: It looks like ROM Manager has messed something up. I have never seen a screen like the ROM Manager screen that occurs in the bootloop right after the Google screen before. Unless maybe when making a nandroid backup through ROM Manager, not sure about this. But it shouldn't be there in a normal boot sequence as far as I understand it.
The only way I can access my Nexus7 is via USB on my PC. And I have like 5 seconds to act while this ROM Manager screen is on, that's the time frame when my PC says "Nexus7 connected" and even the Toolkit finds the device and says it's in "ADB mode", then prints the serial number, but sadly after that it waits for the device to enter adb mode forever.
EDIT: And of course I can get access in APX mode, but from what I have read there is no way to do anything because commands etc. to install a new bootloader are not known (yet?).
Thanks a lot for your help and patience, it actually helps to know there is someone who reads this :good:.
It's not the end of the world if I can't reanimate my Nexus7 but it served me so well for almost a year and I really like it .

Hello again, Jagutherrschaften...
Sorry for taking so long to get back to you, but I've been really busy with non-Android stuff all day.
Before I signed off XDA early this morning, (Fri, UK time)... and before you posted your explanation of how you got into your undesirble predicament, I was trying to think why your Nexus 7 is attempting to boot into CWM. It's something I've never seen before... it occurred to me, CWM may have been incorrectly flashed to the boot partition, instead of the recovery partition. This would go some way to explaining why your Nexus 7 is attempting to boot into CWM instead of normal Android.
So in an attempt to replicate your situation, I fastboot flashed CWM on my Nexus 7, to the boot partition with...
Code:
fastboot flash boot recovery-clockwork-touch-6.0.3.8-grouper.img
...instead of (and correctly)...
Code:
fastboot flash recovery recovery-clockwork-touch-6.0.3.8-grouper.img
Upon completion of this flash, I hit START (from the bootloader)... and as expected my Nexus 7 booted into the Google logo, and then directly into CWM.
...but it didn't bootloop as depicted in your video, it just ran CWM as normal..
I booted several times into CWM, but no bootloop. (It's kind of weird having two custom recoveries installed... there's an option in CWM to restart Recovery, which upon tapping, my N7 booted straight into TWRP !, which is my Custom Recovery of choice. And resides correctly in the recovery partition. I had to make a conscious effort to reboot as normal, in order to boot into CWM).
Anyway, more puzzled more than ever, I fastboot flashed the Jellybean 4.3 stock boot .img back to it's rightful place, rebooted the tablet, to make sure everything was working as normal, and went to bed.
Later, after you posted, I re-read it many times (and took a look at the links), and re-watched your video several more times (by the way, Nandroid backups don't backup the bootloader), and nothing occurred to me; no 'euraka' ! moment.
The bootloader is obviously still intact... if it wasn't, then your Nexus 7 wouldn't boot at all. Besides, it's there, visible, with the unlocked padlock symbol !
I'm inclined to tentatively agree with your assessment that ROM Manager screwed something up. I haven't used ROM Manager for ages, due to known issues on my Advent Vega. And on the Nexus 7, I just use fastboot. On the Vega, you use a command called flash_image to flash images, and is syntactically very similar to fastboot.
Sticking with my Vega for a moment... some users are unable to boot into CWM at all. And nobody seems to know why. But a while ago, somebody did some research into this problem, and it was speculated that on some Vegas there are BAD NAND BLOCKS (like bad sectors on a hard drive, only on a chip instead) in the MISC partition, where a binary state flag is set, telling the tablet to boot into Recovery instead of Android.
Now it's a bit a leap... and hugely speculative... but I wonder if the MISC partition on your Nexus 7 may have become corrupted... ?POSSIBLY? as a result of using ROM Manager... and that is telling the tablet to boot into Recovery instead of Android.
This is a far from satisfactory explanation, though, for several reasons...
* I'm not sure how far you can extrapolate the partition structures of one completely different tablet to another completely different tablet.
* It doesn't explain why your tablet is bootlooping and mine didn't (after replacing the stock boot.img with the CWM recovery .img in the boot partition.
* And finally... I'm still baffled why VOL DOWN+POWER ON doesn't break out of the bootloop and boot directly into the bootloader. Everything I know about the Nexus 7 tells me that this should happen... and it's always been the case, that as long as you can access the bootloader, the tablet is recoverable.
I'm afraid I have nothing else to suggest or try... other than what you've tried already.
I can only offer my apologies that I was unable to assist you... maybe somebody with more technical expertise might offer some new insight or suggestions.
Rgrds,
Ged.

Hey again GedBlake.
The last thing you have to do is apologize for helping me a lot, reading through all my text and making things clear for me. And even more you flashed stuff to your device to test if my situation can be reproduced - good that it's not . You've spent a lot of free time just to help, that's really great :good:.
With my bootloader still being intact and the device being recognized by my PC I wonder if maybe I can manage to fastboot flash a different bootloader and/or a new recovery which might maybe break the silly loop when booting. That's my only idea left but if the bootloader isn't in fastboot mode at some time during the loop this won't work too. But I'll give it a try, it's better than cutting tomatoes on my Nexus7 :laugh:.
Thank you very much for your help. If there is anything worth reporting I will of course.

Thanks for your kind words... they're appreciated.
Unfortunately, before you can fastboot flash anything, the Nexus 7 needs to be properly booted into the bootloader (the screen with the green Android lying on its back, and the word START adjacent to the POWER BUTTON)... and that requires breaking out of the bootloop first.
Indeed, if the VOL DOWN+POWER ON button combo was working as it should... breaking out of the bootloop would AUTOMATICALLY boot your Nexus 7 into the bootloader.
Finally, your bootloader doesn't need to re-flashed. One you have a stable bootloader boot, normally, (and the easiest way), would just be to flash back to factory stock.

Ged.

Hey again.
Thanks for your explanation, I am not really a newbie with PCs and Tablets etc. but some things are not very interesting until you really need to know them. Like bootloader and fastboot in Android.
So the conclusion in my case is that maybe some day someone will find out how to get access to the N7 via APX - or to be precise, someone finds out or gets to know the necessary commands to flash something to the N7 over the APX-interface. Right?
Because from what I've read it doesn't really make sense to send my N7 in for repair right? Although it hasn't even had its 1st birthday yet I have no chance to get a warranty repair or exchange as it's very obvious I rooted the device and flashed stuff (the damned ROM Manager-screen clearly shows this). And ASUS charges 90 $ (or €, don't know) just for diagnosis, that's a bit much for a device that cost 199 €.
Any further advise? Could I buy a broken N7 from eBay for example and repair mine this way? I would have to change the mainboard right?
Have a nice sunday everyone .
U said you opened the battery...so wen u plugged it back in again,u shouldn't be in bootloop technically... Just a boot!...wat happens if u press the volm down and power button combo just as u insert the battery?

And ASUS charges 90 $ (or €, don't know) just for diagnosis, that's a bit much for a device that cost 199 €.
Any further advise? Could I buy a broken N7 from eBay for example and repair mine this way? I would have to change the mainboard right?
Have a nice sunday everyone .

Hi, Jagutherrschaften...
Really sorry it had to end like this... but... perhaps it doesn't...
Nothing about your situation makes logical sense... but reading through your posts again, I find this- On the 3rd October, you posted...

Thank you for your answers. I tried every combination and kept the keys pressed for 2 mins. Nothing. The only thing I can actually do is shut the device down by pressing POWER + VOL UP for a long while.

QUOTE FOR EMPHASIS:- "...by pressing POWER + VOL UP for a long while..."
This key press combo doesn't actually shut down the device... it just pushes it into APX mode. It just looks like it's shutdown.
But that's not my point... my point is your Nexus 7 detected that key press interrupt... and acted accordingly.
It did what it was supposed to do.
Maybe you hit the buttons at JUST THE RIGHT INSTANT during the bootloop... and if it can do it for one key press combo... it can do it for another. Namely, POWER+VOL DOWN.
And for this reason... I think you need to try and try and try and try and try again... until you hit the same PRECISE TIMING SWEET SPOT... such that POWER+VOL DOWN takes you into the bootloader.
Vary the timings a bit here and there... alternate pressing the buttons, both before AND after when the Google logo appears.
By your own account... you've already done it once (you just got into the wrong mode... APX mode instead of bootloader mode).
But here's the danger... if after your Herculean efforts, you do manage, finally, to access the bootloader... you absolutely cannot afford to reboot the device normally until after you've fastboot flashed back to factory stock... otherwise the whole cycle will begin again.
So... you need, in preparation...
* A fully charged Nexus 7.
* All the drivers needed (if you don't already have them) installed on your PC.
* The Jellybean 4.3 Factory Stock image downloaded (see my Sig, second link) and unzipped and ready to go.
* A working knowledge of how to use Fastboot.
* And finally... an indomitable spirit! of perseverance... and, of course, a fair amount of free time.

I am convinced that your tablet is recoverable.
It's gotta be worth a shot... "once more unto the breach, dear friends", as old Bill Shakespeare would have it.
Anyway... the very best of luck.

@neo45215:
Technically yes, but my N7 doesn't seem to know this . Of course I've tried to get into fastboot mode right after putting back the battery as well. No chance, same bootloop.
@GedBlake:
Thanks for the encouragement, I will for sure give this a try (or several long trys to be precise). Hopefully tonight I'll have a lot of time to press keys .
And my answer to what Bill says would be: "To infinity... and beyond!"
No success so far, I tried pressing buttons for at least 1 h, nothing...
Just wanted to update the status .

Facing same problem
Hello guys. I've done pretty much the same thing and my tab is in the same boot loop that this thread is all about.
The interesting thing is that the ROM I flashed is also KaosDroid7.0.0. I'm unable to prevent any further insight. Sorry for bumping. My clockwork mod version is btw, 6.0.4.1 which proves that the problem might not be clockworkmods or even ROM manager's problem. Since I hadn't used ROM manager.
Also, Is there any way whatsoever to use this APX mode? To fix my nexus.
---------- Post added at 02:05 PM ---------- Previous post was at 01:57 PM ----------
Well, I followed OP's steps almost exactly. First I'd restored the Kitkat factory image, and then I'd proceeded to install the KD 7.0.0. And after that, I realised I'd forgotten to flash Gapps. So I rebooted and then went into CWM to reflash and after that is when my Nexus 7 became useless :crying:

installed MIUI on my KF using TWRP a few days back. went well, played around with it, then decided to go back to stock.
Wiped caches and flashed update.zip (stock rom for KF) and all appeared to have gone well..... BUT..... the battery was/is apparently too low for the device to charge (but wait, it gets better)...
when the device fires up I get the white/orange kf logo animation, then when boots I see the homescreen (without the notification/toolbar at top (just bookshelves,standard icons and bottom row of icons).... as soon as that appears I get forceclose messages for
-android.process.acore
-process.android.providers.calendar
(happens right after the UI starts loading ... if Im quick enough I can get one of the homescreen apps to load, but the device (after just a couple of seconds) just goes back to the white/orange logo animation and starts the boot process all over... whether I click force close or not it just restarts the nasty process).
in the brief time Im able to have it on I cant get the kindle fire utility to recognize it so I can get TWRP back on the device to try to re-flash stock.
probably just a paper weight now Im guessing, so I'll either take over my wifes KF or get a new one, but thought I'd mention my experience here to see if anyone has seen/heard of this before and as a warning to other noobs who know just enough to be dangerous like me!
Thanks all.
Have you tried charging it? Just plug it in with the stock charger and let it sit overnight. Then try the re-flash.
Let it charge, then just flash a new rom.
left plugged in with AC charger all night... the force closes just happen over and over and because it doesnt fully boot (Im guessing) I cant get to point where I can use kf utility to get twrp back on to handle boot. i think trying to flash with such a low battery made the flash go horribly wrong and thats the cause of the force closes??? I wish it had hardware buttons like my galaxy s!
Your device is not bricked alright?
Now that the device is fully charged, just go to KFU, on the option 1 (bootmode), choose recovery (5001).
Then turn off the device completely holding the power button for 15 secs or more.
Then plug it to USB and let the KFU set your device to recovery.
Then it will restart and go directly to TWRP
The fact that it boots at all goes to show you didn't brick it.
A few months ago I couldn't get passed the splash screen.

Thanks... KFU doesnt recognize the device at all during the 'boot loop-like' process it runs through before the 2 force closes and the eventual automatic reboot..... I followed your steps and it just kept showing waiting for device and the KF goes through the boot > force close > restart process.... its like ground hog day.
Thanks though, I appreciate the response/help.

Yeah, I see your point... but the force closes and the fact that it never shows the menus / top notification bar and icons, etc. and that seemingly, the KF os never loads fully keeps me from getting to a point where the windows drivers recognize the device and then allows me to get KFU to work with the device.
sort of stuck but not technically a brick I guess.
There is no such thing like KF never loads fully.
Or it loads or not. FCs is something that happened on the install of the rom
You have TWRP and cant fastboot?
Try to redo the steps to install TWRP and install FFF 1.4a by hashcode
He doesn't have FFF or TWRP anymore, as he flashed Amazon's stock update.zip
Your only solutions are either the USB trick (cracking open the KF's case and shorting specific pins) or getting a factory cable (recommended) to force the KF into fastboot mode, from which you can flash FFF and TWRP, then boot into TWRP and fix the mess.
Sorry, after i went from stock to custom roms, i never tried to go back to stock, didnt know that we lost fff and twrp when doing it.
Thanks, Dasanko, I'll do a search for the cable and see where to buy it and will go that route. Thanks again all.
FastBoot
Something similar happened to me and I did this:
Even though your Kindle Fire isn't recognized by KFU you can run it and select the option #5 (Install Latest FireFireFire).
When you do it'll probably error out attempting to get your device into fastboot but you'll get the prompt "( waiting for device )". Once that happens let your fire loop again and this time the window will be big enough for FireFireFire to be flashed into your device and leave the device in FastBoot...
After FireFireFire gets installed run KFU again to install TWRP and you'll be able to boot into recovery by poking the power button repeatedly in the new boot logo.
Hope that helps! (That's how I un-looped mine)

Np, it's just it doesn't flash just over the system, but also overwrites the recovery and bootloader with their crappy stock ones.

I like this approach and think it MIGHT yield some results (but what do I know- I caused this afterall!).... Im going to let it stay in its little reboot / force close loop and have KFU sitting at FFF (waiting for device).... then if it looks like this works (how will I know exactly? the boot process will change how exactly (what should I look for, basically)) then I will do same with KFU and TWRP installation option do its thing. Thanks.
Something similar happened to me too. I was reverting my CM9 modded Kindle to a stock one. After flashing the 6.3.1 update, I was getting weird FCs whenever I would boot into the stock OS. I finally managed to get to the Factory reset option in the menu and that fixed the issue for me.

Encouraging!.... what exactly did you do to get it to work for you - if you recall... i've just had it spinning through the loop with KFU sitting at waiting for device -- no results though... so seems pointless for me so far.
Little bit of info as to why/what is causing the issues discussed here:
The stock bin backs up data during the restore process and than restores it back along with the ROM (those of you familiar will already see the issue here but I'll continue); problem of course being there that if you restore data from a ROM like CM9 to the gingerbread based/neutered stock OS (or even to CM7 for that matter), it is going to cause all sorts of headaches with force closes and stuff just plain not working.
In short, for those considering trying to return to stock please remember to wipe data before attempting to flash the bin (at least until someone decides there's enough of a demand to make a cleaner return to stock method).
As for the OP, do what was suggested with the factory cable and you should be set; good luck.
Edit: the above posts regarding factory reset might work to as that will delete data but you would have to be able to get to that part of the settings menu, which depending on what's force closing may or may not be possible.
Your exactly right Sblood86 many are slipping on this bannana peel here lately trying to revert back to stock some with even more dire consequences not just a literal shock to it completely changing systems but also how data is rehandled. Could be a better option for some to do full wipes and flash something near stock like modaco to prevent this mishap.
This entire thread is ridiculous.
Hi all,
I thought I'd consult the brains trust to see if anyone thinks this is salvageable. Was using my A500 about 2 hours ago, suddenly the screen powered off. Thinking nothing of it, I held down the power button to restart it. When powering back on, nothing appears to happen except for the power button lighting up. No screen on, no vibe, nothing except the power light on.
Tried power cycling a few times to no avail. Tried the reset button. Tried the Vol+ Power and Rotation switch reset. Nothing.
Out of morbid curiousity, I plugged it into the PC and switched it on and I get an APX driver being installed. So, clearly something is happening here.
It has done this once before and came back to life of its own accord very shortly afterwards, this time it's been dead for quite some time.
Any suggestions? It's well out of warranty now, so I doubt Acer would be interested in it at all.

In the Dev threads, or possibly Q&A, there is a thread called "stuck in APX mode". In there I believe are some steps to see if you can recover.
But, if you're in APX mode, you could probably try NVFlashing the bootloader and recovery the old fashioned way manually.
But look up that APX thread first. Will probably have the answer. I'll see if I can find it in a little while, if you don't find it first.

Thanks MD. I looked up the threads you suggested, and after a lot of screwing around I have installed the APX drivers and used blackthund3r's APX Flash Util 0.3 (The link is broken to the current version) to attempt a recovery of my tab.
Its now sitting at an Acer screen, "Entering Acer Download Mode" while the flash util is sitting at:
Nvflash started
[resume mode]
It's been there for about 10 minutes now, no progress to report. Is it worth just sitting it out, or now that the damn tab shows SOME signs of life, can I just restart it and reset to factory?
And then most bizarre of all. I declared no progress, rebooted it. It went back to APX mode.
Re-ran the blackthund3r tool, it didnt do much so I bailed that. Restarted tab and attempted to load recovery (vol + and power) and it booted normally.
What the hell...

erm for now i would make sure you have all backups of data, cpud etc,.. just incase. you can just sit em on your computer i always try to keep a nandroid of all 3 of my devices each month or so.:good:
edit: and of course keep the link for the thread MD recommended.
Gee. Sounds exactly like mine....
The only thing I haven't tried is an update .zip, but I don't hold out much hope.
Considering parting out at this point....
Yeah, I dont have high hopes that it will last a whole lot longer. Up to this point it has been running Acer OTA updates only, no custom ROMs and no root.
I restarted the tab a little while ago and it went back into APX mode again and stayed there. Some more furious button mashing and attempted restore-mode boots, and it booted normally.
I made the point of wiping it this time using the Vol+ & Power & Rotation Lock trick and its been ok so far.

I have a cousin in Jamaica. She might possibly help (chicken foot and some frogs blood...voodoo you know)
Here's What I think.
You got some corrupt data or a partially bad devblock. This might explain the strange behavior on boot.
Like the tab really doesn't know how to boot.
Personally I would do 1 of 2 things at this point. Either;
1. Root that thing, and try running Timmy Deans root back to 3.2. This should reset your partitions back to normal. Then work your way back to an ICS rooted, Bootloader, and custom rom.
2. Leave it alone, and don;t turn the tab off. Clearly some partitions are messed up at this point. The toggle of the lock usually wipes user data. But the core issue is still there.
If it were me, I would pull out the nuclear missile and go for it all.

If dolps is like mien, the first time he tries to go into recovery, it will crash again...

Tried blackthunder flash again, failed.
Went to turn off to get out of APX, and it booted!
Now boots, boots to recovery and boots to primary.
I have no explanation.

First, is this a SOD?
I can kill it by booting into recovery and get it back by using Blackthunder flash tool to go into APX and letting it sit for 20 minutes or so. Close the program, unplug, reboot and it is back. I would like to use timmiedean (td) and go back to square 1, but it fails at the image detect ( displays ICS 4.0.3 Civato as the current image, a red X for the new image). Has td been proven to work reverting from ICS? Will a boot recovery reflash and a new ROM flash solve this? Is there another way to get out of ICS back to HC?
Any suggestions/comments welcome!
EDIT: I flashed FLEXxx V4. Shut it off, problem still there....
Really frustrated. Trying to use the timmiedean tool, but it requires that the unit be shut off in the middle of the process, which kills it. Does anyone know the whereabouts of the blackthund3r revert tool, or the .apx package for his flash tool. I can't find it...
I'm done with this one. On Ebay for parts.... GONE!!!

Hey,
I need some help with my Nexus 10, it's stuck at the moment.
I ran fastboot oem unlock via the Samsung Google Nexus 10 ToolKit 1.3.0 (updated for 4.2.2) and as soon as it was done it rebooted and was stuck...
Booting normally it gets to the bootlogo and just sits there forever, going round and round and round.
If I try to boot into fastboot it shows that it's unlocked but I can't change change to recovery using the volume rocker it's just a solid static screen, only choice is to start which boots back into the normal boot logo.
I have no way to use adb or fastboot... it's just stuck :/ How do I recover/unbrick this?
Any help would be much appreciated.

I'm on the xda-devs irc at the moment and we've got so far... but still its messed up.
- Recovery is dead (can't get into it atm, orange triangle guy every time)
- Flashed stock via fastboot and unrooted, but on reboot I get the triangle guy.
- I can boot into unsecure roms (temporary)
- I can boot into temporary recoverys, clearing cache works but davlik cache and factory reset doesn't work both say "failed"
I'm currently awaiting the guy whos been helping me get back from the shops.
From what I remember you need to either install something or run a command after "oem unlock" for security reasons. Android wont let you boot back into the OS until you have wiped all the data after the unlock.
The orange guy means it's working. There's a button combo to hit at that screen to get the recovery to boot. Once there do a factory reset and your done.
That's why toolkits sick, they teach you nothing and when they break your stuck

The pressing 3 buttons at once; cycling to recovery... method wasnt working because there was no recovery accessable what so ever and temporary recoveries weren't working.
That's what a few guys in IRC said too about the toolkits haha

Okay, updates for everyone just incase someone else gets the problem.
- Factory Images via fastboot flashed fine but never stuck, just kept returning me to triangle dude.
- Fix permissions, did nothing
- Restoring stock recovery did nothing, I still couldn't get to a recovery.
- Temporary recoveries only had limited functionality.
I decided to unlock an already unlocked phone again
I flashed stock, Ran file permissions
Used the temporary recovery to clear the cache/davlik (previously didn't work)
I re-rooted, Installed TWRP 2.4.4.0, this finally stuck.
I double checked that it had stuck by booting the system, rebooting into recovery, powering device of and powering it on to Android. It was all working perfectly.
I then made my backup and put a custom rom and kernel on, it's working lovely now.
It seems that somewhere during the oem unlock it messed up some partitions or something resulting in recoveries and flashing not to work/stick.
Good to hear it's working for you. The issue is that the stock N10 bootloader does not wipe the data partitions correctly as it should. So after an unlock you need to go into the stock recovery and wipe it. Boot once, then go and flash all your flasheys

That's the thing, the recovery wasn't available in any way shape or form and temporary recoveries wouldn't wipe the cache... the oem unlock went wrong somehow even though it had full power, wasn't interrupted or anything.
I'm glad it's all working now, I thought the device was completely dead at one stage.
I think you had the problem almost everyone runs into:
As you can see in the video, you just have to try for a bit to actually get the recovery menu to open - My heart dropped a little before I knew that as well

Hi,
My Nexus 4 is stuck in the Bootloop (where the Colored Dots fly around that should form the Logo) and I don´t know hat to do anymore. I´ve read dozens of threads but not a single Solution could be found...
I tried several Factory Resets and Cash Wipes with the Recovery Mode and Flashing Stock Android on it. I also just let it try to boot up over night, but after 8hours it was still stuck in the same Bootloop.
I´ve never Rooted my Nexus or something like that it was Stock Android all the time (haven´t used it since like half a year, when the Bootloop appeared first, but now i broke the Screen of my Galaxy Alpha which is too expensive for me to let it fix...).
One Thing thats different from many other People that get stuck in Bootloop is the fact, that after Holding the power button to power it down, i can enter the bootloader (where i can find recovery mode) if i only push the volume down button, not the power button. I also have to go into bootloader and select "power down", if i don´t want it to try and boot up again without me doing anything.
I apologize for my bad English (if it is, i´m not sure) and i´m thankful for every hint on what i could do, since Walking aroung without a Smartphone feels weird as f*ck

Hi,
My Nexus 4 is stuck in the Bootloop (where the Colored Dots fly around that should form the Logo) and I don´t know hat to do anymore. I´ve read dozens of threads but not a single Solution could be found...
I tried several Factory Resets and Cash Wipes with the Recovery Mode and Flashing Stock Android on it. I also just let it try to boot up over night, but after 8hours it was still stuck in the same Bootloop.
I´ve never Rooted my Nexus or something like that it was Stock Android all the time (haven´t used it since like half a year, when the Bootloop appeared first, but now i broke the Screen of my Galaxy Alpha which is too expensive for me to let it fix...).

Is your bootloader unlocked? When you said you flashed stock do you mean you flashed a zip in recovery, or flashed it via fastboot?
I unlocked my bootloader and used the wugfresh toolkit to flash stock 5.1.1. in my nexus.
After hours of online search i finally found out how to "solve" my Problem. Apparently my power button was stuck (wrote sth. like that in my 1st post but wasn't sure yet), so i just slammed it on the desk with the side where the powerbutton is located and it worked!!
I think thats something you should tell everyone who is stuck in a bootloop an not even reflashing stock Android helps
Now i got the Problem that i can't fit my nano sim in the micro sim slot of the nrxus , wouls be nice if someone got an advice in this, but maybe i should just go and get an Adapter tomorrow
Greetings, Slix
If you do not have any data on it, you can reflash the whole device by downloading the nexus 4 factory image here https://dl.google.com/dl/android/aosp/occam-lmy47v-factory-b0c4eb3d.tgz
You will need adb and fastboot which you can get here http://forum.xda-developers.com/showthread.php?t=2588979 (if the latest version does not work use version 1.3)
Then simply unzip the factory image with 7zip and run
Code:
flash-all.bat

Good evening XDA,
I've got a Nexus 6p (obviously), and can't get it to boot. Unfortunately, I don't know the exact history as to how it's in this state.
I've tried everything I can think of and read every guide/steps/forums I can find that relates to my situation.
I can get to the bootloader and issue Fastboot commands. I've got adb/fastoot/drivers installed via the sdk/platform tools, and drivers are up to date as far as I can tell.
-I'm using the OEM cable attached to my computer (Surface Pro3, Windows 10)
-I can unlock/re-lock the bootloader as I wish.
-I've tried WugFresh toolkit, flash factory + unroot. All completes, but phones continues to loop even after leaving it for an hour+.
-I've tried Heisenbergs guide for manually flashing stock google images via fastboot to no avail. Tried several different google images. Everything completes, but it still just loops.
-I can get all fastboot commands to complete with no errors, but the phone just simply bootloops at the google logo, or if I leave bootloader unlocked it loops with the orange triangle & google logo. I have left it looping for at least an hour+, but it doesn't finish:crying:
-Stock recovery or a fastboot flashed trwp recovery simply won't boot, it just goes to the google logo and loops, I don't get the dead android w/triangle. "Recovery" in the bootloader selections is RED, if that means anything. Tried fastboot commands to boot recovery, but just sends it to the google logo and loops.
-Adb commands don't work, only fastboot commands.
-During flashing a google stock image with fastboot, the only thing that stands out is "max download of ####### reached", or something similar, but it still completes.....?
Seems to me that I've got a true brick (first ), and just need to send it in for repair.
Any help would be greatly appreciated. TIA.
Well, personally I believe it is a brick. Because I had something similar and it was fixed by a simple complete wipe of the phone - did you try that, and follow the order for fastboot flashing?
As for replacement. I have a dent in the frame that effected the volume button until I pushed it back in. I contacted google support and they told me since it was physical damage. That I would have to contact Huawei for repairs, and they promptly gave me their number. As for your case it could be a board failure and could go under warranty through google. Good luck! Off to help more people.
PS: Use a twp version higher than 2.x.x, that was what my issue was.

Thanks for the reply. I thought (hoped) it might be a button issue too, but there is no damage to the phone, and buttons work as they should in the bootloader. Gave them a slight tap, but same results.
As for the "complete wipe", I can only erase/format via fastboot (or WugFresh ToolKit) since I can't get to recovery, and that hasn't given me any different results.

Does all the data in the bootloader look fine? The storage size etc?

As far as I can tell, everything looks normal. Is there anything you know of that would raise suspicion? I'll post exactly what it says when I get back to it.

Usually with board failure - that I saw in other threads - there are missing fields. My phone had a little glitchyness after I accidentally flashed the userdata.img - which caused my 128gb to become 32gb, which I found amusing - Other than that, I don't know. I'm sure others would reply.
I powered the phone off via the bootloader menu. Came back to the phone and powered it on, and it started the bootloop. I only held down the volume down button (during loop), and it booted to the bootloader. Is this normal? I realize I'm probably grasping at anything, but I've got some time to kill and just curious if it loops and only the volume down button is held should it go to the bootloader?

TWRP 3.0.2-1 may have been used on this device and a restore may have been attempted, causing the EFS partition to be damaged. There a thread in this qna section by the tittle of Lets get this......I don't remember the rest, but it has a post concerning what to do to fix the bootloop.

Thanks for the link, and I've been reading the "Let's figure out this brick together" thread. The link you posted requires ADB commands to work to fix the EFS partition, but I can only run fastboot commands. ADB nor Recovery work on my device. Still reading...
Woohoo! Huawei replaced the phone, no questions asked. I think the saving grace was being able to flash stock images, and relock the bootloader. May be helpful to anyone else in this situation that can only run fastboot commands, and no recovery.
