If you turn it on while holding "dolume down" do you get the android+! screen? Some go into recovery if you touch the bottom right corner of the screen, but on some you have to hold volume up + down together. I had this problem today!
If you actually can't get to the screen with the android+! then I don't know what else you could do :-(

I really can not, no way to go to the screen with the robot android! he goes right on the logo motorola M!
can it be hardware problem?

1) Did you use the correct flasher? rsd4.9 with motorola driver installed properly.
2) If (1) not working, you could use motorola own service update from their site.

but no results!

don't worry about it, dude.
maybe you can try the way followed:
1.power off your defy;
2.remove the battery from the phone;
3.plug the usb cable into the phone without battery;
4.open RSD and chose one of the roms your listed, but 3.4.2-177-005 NORDIC prefered,
5.take the battery into your phone, now your can see the "connected" on RSD;
6.click the "start" button to flash;
7.wait the phone reboot completely, usually it'll reboot.
if not reboot, remove and on your battery, power on your phone, then press the "volume - and power" botton together, you can enter the robot screen, press volume up and down botton together, usually you can enter the recovery, then chose wipe 3 and 4, totally you can save your defy~~

Be sure to have enough battery while flashing..

Get the phone into bootloader (hold volume down when switch on) and flash an SBF like one from the list you've attached using RSD lite. Surely you have used RSD Lite before?

It seems you have the same issue I have on my Defy as per this thread: http://forum.xda-developers.com/showthread.php?t=1095444
I’m also unable to get into recovery or get to the Android Robot screen using “Power + Volume Down”. Hopefully we will be able to figure it out and get this issue fixed.

This same friend, I have the same problem, is this a hardware problem? I move the roms but not normal
Vol I login recovery - + Power key

http://forum.xda-developers.com/showthread.php?t=966537
Try flashing nordic, if fails arabic, if fails, 2.3.3, if fails probably corrupt nand broken hardware.
Before and after every flash always try to access recovery (volume down) and WIPE. reboot and wait crossing fingers, if it fails to boot flash next sbf, try to go recovery + wipe; reboot, cross more fingers; if fails to boot try next sbf and repeat.
The reason for this is that you can flash a lower version but it wont boot, so you have to flash a higher and higher version until you get one that works.

I tried to help someone with this problem before to no avail!
Everyone who is saying just wipe in recovery, or just flash with RSD blah blah blah, need to understand that he CAN NOT access recovery and HE HAS flashed multiple roms using RSD 4.9, read the OP. Im convinced this is physical hardware failure or similar. We all know the drill to recover our precious defy's in the event of semi-brick ie: bootloop or corrupt code. However this is more than a semi-brick. We are talking about successful flashing and still no access to recovery and infinite M logo!
I walked more than one person with this problem through every known procedure to bring these phones back. Even using sbf_flash for linux doesn't work as this is the only way I flash anymore I don't bother with RSD anymore. The thing is it DOES FLASH SUCCESSFULLY just no recovery or boot!

OMG Exactly!!!! i have same problem and nobody seems to be able to tell me what to do, they keep saying same thing about trying various SBF's and Vol down + power method. No matter what SBF file I successfully flash with, i cannot get into boot recovery mode.

I have heard before from desperate users that they were able to revive their phone by flashing a full 2.3.4 sbf. This however comes with downsides of not being able to downgrade to froyo by flashing ANY froyo sbf's. There is a way to downgrade back to froyo but its a dirty method. Even after downgrade you can't just flash a sbf, you will always need to restore nandroid and flash fixed sbf

Nexus 4: Boot loop with locked bootloader and no USB debugging - HELP!!!

Hi all,
First time posting on here (but I read the forums often - for guides etc).
Bought the Nexus 4 and I unlocked the bootloader and rooted the device. Kept to the stock Android (JB 4.2) however I locked the bootloader again.
The boot loop occurred after a restart after I did the following things:
1. Used Battery Calibration to calibrate the battery. Left the battery to drain and then charge to 100%.
2. Used VM Heap to change the amount and restarted the phone. Boot loop ocurred.
I have tried many things after reading this forums and other forums but there seems to be no answer to this issue.
Things I've tried are:
1. Booted into recovery mode and wipe data/factory reset many times - still has boot loop
2. Used Nexus Root Toolkit and tried the various functions on there. Fastboot doesn't detect the device (even though its in fastboot mode) in order for me to unlock the bootloader again and flash it with the stock ROM. Windows (8) does detect it but can't load drivers for it. Been through all the instructions on the Nexus Root Toolkit - reinstall drivers, cleared the device from device manager, cleared it from usb list etc. Fastboot just won't detect it to allow me to unlock!!
3. Let the battery drained and tried factory resetting but doesn't work (not tried fully charging it and then resetting though)
4. Been trying various other things which I read on the forum(s) but nothing seems to work!:crying:
Literally spent the whole day trying so many different things. Seems like I discovered a whole new unique problem to causing boot loop on the Nexus 4. I don't want to have to send this back to Google for a replacement if they give me one - hopefully with the locked bootloader and the data cleared, they won't know I've rooted, not to mention its micro-sim and my backup feature phone doesn't take micro-sim :crying:
Has any one had this issue before and fixed it!? Would really appreciate the help/guidance!
My first time rooting a phone, didn't do it before on other phones because thought knowing my luck I'd brick it beyond repair! Luck would have it, that exactly what has happened.
Appreciate the replies and help on this!

I'm having the same problem!

For the toolkit to see the device, you need to put your device to fastboot mode by pressing vol (-) and then the power button (the phone should be in powered off mode to do this).

I had a boot loop issue. It was stuck on Google logo - the white logo.
I couldn't go into recovery either.
My fix was to flash the stock recovery.IMG
I too couldn't detect the device however I kept trying.
If you face a problem getting into fast boot mode try pressing vol up + vil down + power. Didn't work for me but worked for some.
Let me know how it goes I'm glad to help out if I can

Having USB Debugging ticked WHILE IN ANDROID has absolutely no effect on whether or not your computer can see the device WHILE IN RECOVERY OR FASTBOOT.

Didn't fix it in the end...no matter what I tried. I got a replacement from Google (thankfully they didn't charge me for the new one!).
BTW the batch of Nexus 4 released in end of Jan/early Feb has a much better battery life than the one I got from the batch released in early Dec. Won't be rooting the new Nexus 4 in case sh*t happens again but no doubt will get tempted again somewhere down the line!
Thank you to everyone who replied!~ :good:

HELP! Bricked Nexus 7, cannot boot into boot loader

Hello everyone, I'm new in this forum and have just bricked my Nexus 7 .
I was not very happy with my Nexus 7 with JB version 4.2.1, it lagged and took long time to load apps etc. I used the Nexus 7 toolkit to unlock my bootloader, flash recovery and then tried a few custom roms. I eventually flash the official 4.1.2 firmware from google but the constant notification for firmware update annoyed me and I decided to root and get rid of the firmware update notifications by installing fotakill.apk.
But when I tried to root using the Nexus 7 toolkit, I chose the option to sideload the zip files for rooting automatically. It asked to flash my boot loader to a lower version (3.34, mine was 3.41) and afterwards it rebooted the device and eventually got stuck at a screen with these lines:
now send the package you want to apply
to the device with adb sideload <filename>
after a long time without anything happening, I suspected that things went wrong and pressed the power button for a few seconds and the device turned off. Now I cannot turn it back on, when plugged in it doesn't show the charging battery, also I cannot boot into fastboot mode by holding Volume down + Power button. The screen stays black the whole time.
I even tried to open the back power and pull the battery out and in again and try to turn on the tablet, nothing happens. I remember the battery level was like roughly 90% the last time the tablet was working, so I don't know what went wrong .

Press all buttons on the side simultaniously untill fastboot/bootloader mode appears. This should work, no matter if your device is booted or not, or soft bricked or whatever. Then: http://forum.xda-developers.com/showthread.php?t=1907796 .
If it doesn't work however (like after 30-60 seconds), then connect your nexus 7 to your PC. Go to device manager and identify your device. Does it say apx-mode or something like that? Then your device is possibly hard bricked and you might find some answers here: http://forum.xda-developers.com/showthread.php?t=1879228 .
Your should not have used rootkits. Most of these topics appear after people using toolkit. Learn to use fastboot. It's the only program you'll need for the nexus 7. Yes, it's a command line tool but at least it forces you to think before flashing. For example, it was not necessary to downgrade your bootloader. I really don't get why you did that. Also, if you want to run a stable 4.1.2 without the annoying update messages, you can, for example, flash cyanogenmod 10. It's stable, very smooth, and way better than stock.

Thanks I did a search and finally found an answer. I was running fine on my N7 with PACMan and suddenly it got stuck booting up. So I booted into recovery and reflashed the ROM, and wiped dalvik and cache. When I rebooted it went to "Android is upgrading" like usual after wiping dalvik, then it got stuck there. So I rebooted again and nothing. Just a blank screen. Your suggestion of holding all the buttons down for 30-60 seconds awoke my Nexus. I'm going to wipe everything and start over.

Unstoppable bootloop after flashing new ROM

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.

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..

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.

"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.

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?

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:

Jagutherrschaften, did you send in your Nexus 7 for repair?

Nexus 4 Bootloop, nothing works

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

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

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
