Hi
So last night when I flashed my new created ROM with CWM, it seems like I ruined my boot loader, and from that I can't find the way to recover
SYMPTOMS:
- black screen
- power button doesn't do anything
- no button combination boots to download mode
- no charghing indication when connected to charger or USB
- no detection in the computer when connected to the USB
Is this the real black screen of death?
How did I get there?
I flashed a ROM through CWM, when it finished I selected reboot from CWM, and since then, all I see is black screen, no indication whatsoever to powering up.
I didn't try a USB JIG yet, but I will at Thursday (meet with a friend that has one)
as far as I understand the only way to recover from this is using a RIFF Box JTAG which requires, taking apart the phone, and soldering small wires to the board, and then reload the boot loader
Where do we go from here?
If it happened to you Please write down:
how did it happened to you?
what did you do to try to recover?
did you mange to recover?
if you did, how did you?
Why is this post so important to everyone?
Because if it didn't happen to you yet it might happen in your next CWM flashing.
So its very important to find a solution or at least the way to prevent it.
- update 31/12/2010 -
Cause
corrupted boot loader , bad sbl.bin flashing
Prevention:
do not flash roms/addons/fixes with sbl.bin
if you must flash sbl.bin, do it while you are sure that your USB configuration is perfect, and do it as less as possible.
Solution (for those who already bricked to black)
you're not gonna like it
find riffbox jtag....

Happened to me too. I was tinkering with the Armani source to hopefully find something of use for Axura, and I bricked it. Same things happened to me. I called att and got a new one.

Did you try removing battery and putting it back and then opening ODIN, holding the volume up/down and inserting the usb to bring it on the download mode. I guess I might have experience almost similar issue with one of the rom. I almost freaked out. Phone wont show if its charging. It wont mount on the pc. But tried all the possible method available several times including adb shell command. And finally I did hear the magical sound from window when the usb is connected and finally it did work.
Also try the adb method if it doesn't go into download mode using volume button combo.

Did u remove sbl.bin
Sent from my SAMSUNG-SGH-I897 using XDA App
Happened to me the first time I ran the OTA update from ATT. Paused the update, and when I resumed it - the phone though I finished downloading the JH7 update and tried to apply it.
It failed to apply and when it went to restart, it never powered on. No download mode, recovery, USB power, Odin, nothing. It was completely dead.
I got it replaced at the AT&T store.
If sbl.bin was removed or corrupted you should call the warranty center. Tell them ota update bricked your phone. Lol good luck
sent from my cappy running di11igaf's rom v2.5 at 1280mhz!!
I think it is just bad luck. I was once being careless and had the battery fall out of my phone while flashing, it interrupted the flash and I was still able to get in download mode to Odin it. Needless to say, I'll never flash again without the back cover on

Yes i'ts probably a bad sbl.bin, but I didn't remove it I flashed a new one, most of the rom's do the same
yeah sounds like it...sry for your luck.but seems like its toast then. keep us posted
But if you had a batch 1008 captivate and you messed up during and Odin flash to stock then your screwed bcuz Odin one click swaps the sbl.bins to make your button combinations impossible. ADB would work but you obviously can't access that. I too have a 1008 and it sucks, that is why I bought a jig.

There is a a way. Whenever you need to flash to stock you must use following stock. http://forum.xda-developers.com/showthread.php?t=818439
This is same as normal stock posted by DG except that it includes sbl.bin that we (1008) need. I use it everytime and 3 button combos for Download, Recovery work great.

it seems like this is not my case
I'm still looking for other people who had my case, and recovered (even with the JTAG riff box) or at least find someone who know's what we shouldn't do, so we don't break our phones.
so whats batch 1008?
This happened to me last night. I was trying to flash the Darky port via CWM and during the flash it became unresponsive. I had to pull the battery. This caused 2 different things. Sometimes it would be a never ending loop of boot screens and then others it would just go into recovery where it wouldn't let me do anything.
From here luckily I was able to access download mode by using the "adb reboot download" command. So I then got into dl mode and tried to flash stock (not the 3 button fixed one) and it froze on FACTORYFS (or whatever it is). I had no choice but to pull the battery. Now it won't boot at all. So my assumption is it wiped the bootloader. I'm not 100% sure but I feel that the reason it stopped where it did was because I didn't run odin as admin on my Win7 pc. I read in another thread that someone had the same problem when they didn't do that either.
If you are in a pitch black room and you press power you can see your screen illuminate, it's just very dim.
I have batch 1008 if it makes any difference to anyone.
Either way I'm heading to the device support center in a half hour or so to try to get a replacement. I originally was going to make or order a jig but people are saying it only works if the bootloader is intact. I originally had hopes because one person claimed that they recovered a completely dead phone with it, but upon further reading all others could not. It seems like his phone may not have been completely bricked.
Update:
Just got back from the at&t device support center. They gave me a new phone without any hassle. They asked what was wrong with my phone and I told them that I was trying to update it and now it won't turn on. The guy tried a few combinations of button presses and tried hooking it up to a jig-like device. Nothing worked so he just gave me a refurbished phones. No questions asked. As I was walking out he said a few people have had the same issue so it's not a big deal.
Either way I thought this would help to realize that there is likely no way to get the phone to boot unless you have a jtag handy.
I don't feel safe to flash rom via CWM.
If you really want to do that, delete the bootloader inside the .zip
So i think i killed mine too
so i get black screen, two button combo gives me SEC S5PC110 Test B/d
I opened odin but nothing Is this toast?
I had this exact problem over thanksgiving weekend. My phone was was was hard bricked I was getting the "phone + computer" it took some effort to get it into download but I got it there and when I was recovering with odin the connection got lost the screen went blue and then nothing. It was dead totally unresponsive no charging or boot screen nothing but once I got a black screen with redlines. After a lot of attempts to revive it I gave up called ATT warranty for a replacement. Luckily I opted for the slow mail service and kept reading. Yesterday I saw the above post and now I can say "yes even now your phone is not bricked even though it does NOTHING"
step 1) first thing I did was charge the battery with my replacement phone as the bricked phone was no longer able to charge the battery
step 2) open odin1 click and hooked up the usb to the phone and computer no battery
step 3) inserted the battery holding only volume up+down
step 4) "BOOM" download mode and a happy dance
I posted this in the"read before flashing" thread there are other people who have recovered from this and now I think that the extra trick to this is getting a 100% battery you need this to flash, and state the phone is in now wont charge a battery.
hope this sound encouraging

It's odd because I keep seeing people saying things like this. I, too, have a 1008 Captivate. My button combos have worked from day one and Odin one click has never messed that up. Maybe I'm just lucky?

I believe there's a "fixed" 1008 batch. Not all 1008s are going to have the problem.

Yeah it's either that or just a misconception spread by the community. Both my old captivate and replacement were 1008. I have been able to get into recovery via the power+volume combination. I was also able to get into dl mode using the vol+insert usb combination.
It's possible I just got lucky on both but who knows.
I, and many others have a 1008 that don't go into download or recovery via the button combos without fixing sbl.bin.

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..

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 .

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.

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?
Hi,
i never touched my Nexus 7 with any other ROMs or such. It was still rooted and kinda original. Now i can't do anything with it anymore.
I talked to the google hotline already and i was trying to start the bootloader which works fine, but nothing more.
1. When i choose Start, Restart Bootloader, Recovery Mode oder Power Off nothing happens, beside Booting failed (Recovery Mode).
2. When i start the phone just with the power button i just see the google logo.
3. When i plugin the power cable i don't see the battery for loading.
I got another device from google with horrorable battery power, so now i wanna try on my own the save my Tablet. I flashed my Galaxy Nexus and HTC HD2 couple of times, so i'm not a 100% Noob.
I was already looking in like 10 threads i found about problems nearly like mine, but i don't got the golden clue yet, sry.
I hope you can help me please.

I encountered identical problem on an N7 (2012) 32gb and try everything that I know how and always get the message ADB not found. Finally I use Skipsoft ToolKit and use option #9 Download, Extract and Flash Google Factory Stock Rom and it works . My N7 was returned to stock with latest firmware.. Of course you will lose all data and still have to unlock and root again
I am not a techie so I cannot explain the details but only share my experience.
I hope it will work for you

If you can't see the white battery picture when plugging in the power cable, I suggest you use AC power, and if you are, try using a different USB Micro cable.
So i was trying the new beta for PA android and when i was on recovery wiping as usual, the wipe process just froze there for a while, i decided to leave it till it worked again but to no avail it didnt budge at all, so i commited the ultimate sin, and powered it off by holding the power button...
when i tried again tu turn it on the tablet would go thru the google with the padlock screen and then show me a black screen with a little logo of clockworkmod and a version number below, the screen itself has no use since no matter what button i press it does nothing, other than that the tablet keeps rebooting after that.
when i try any combination of buttons to access either the real recovery or the bootloader the tablet just plain ignores that im trying to turn it on, just doesnt work, it just turns on if im not pressing anything besides the power button.
to sum up to all my problems i would love to keep trying and see if at anypoint it will turn to bootloader, i havent seen the notification of the tablet being charged... meaning that i dont know if it has enough battery to last me the remaning ideas i had.
So in a nutshell
-no bootloader
-no fastboot
-no recovery
-cant tell if battery or not
Please if anyone knows how to fix or at least get me to a bootloader i would fix everything else, but i really need the guidance here
Have you tried another charger and cable? A simple idea, but not one to over look.
Without bootloader menu or recovery, not much you can do. I'd work on getting into one of those first. Not much you can do until then.

Yeah ive tried 4 other chargers, and nothing new, i know that the os itself takes care of the charging as does the recovery in some cases, but since i have non i dont know if its gonna charge at all or not and trying doesnt sound really appealing since i should save battery in case theres a solution and needs battery power

Dont really know how to check, i mean i could get into the tools and try the command Adb Devices but how should i even begin to test? i mean shouldnt i be in a adb static platform on the device? if i try to get into bootloader it just doesnt turn on, and when it does it goes straight to the black screen with the clockworkmod symbol and numbers

if you have enough battery and can get pc to see is thru adb. you may be able to fastboot a new rom onto the device. You can from pc Request device to go into bootloader or fast boot from the PC..
This is your only shot.. I Would suggest borrow a friends Nexus 7 Full Battery . If you do not know how to do any of this . Use skips root kit and use the unbrick or factory reset. it will force your device into fast boot and flash a new rom.
Good Luck

yeh i know how to use the skip toolkit, yet i hope i have enough battery for the test, because the only friend that i know owns a nexus 7 left the country a few months back, so the battery sounds like its gonna be hard to get. Anyways, as u were saying theres a posibility that while the tablet is rebooting and rebooting it might be able to be found on the adb devices? and use the fastboot, cuz if thats true u would be the hero ive been waiting for...
imma check and tell u later,

Hi,
My brother is having trouble with his Nexus 4 and I was hoping I could get some help here.
The phone won't go past the boot animation, with the 4 floating balls.
It keeps showing that forever (left it for 20 minutes with charger, phone got really hot but did not get past the animation)
- Never rooted or changed firmware. Only updates from Google. (It was on 5.1.1/5.1/5.0.1)
- Sent to a shop, which claimed it can't be fixed (I do not know the reason they gave him).
My brother thinks it is because a weight was accidently dropped on the phone, but the problem only started 3 days after the incident.
No outer damage can be seen on the device, other then a small brake in the back glass.
Thanks in advance to anyone who will try to help
possibly?
Did you just update and it got stuck at the booting up????

Do you have data on it that you want to keep? If you don't you can try booting into the bootloader and unlock it. Then try flashing a factory image. This will wipe all the data on the phone though so that should probably be a last resort.

I have no important data on it.
Which is the safest way to do this? I'd appreciate it if you would be detailed or refer me to a guide, as I want to be careful.
Where should I download the factory image from?
As the name of it states, I wish to get the one from Google, without any changes or addons from users.
Follow this guide http://forum.xda-developers.com/nexus-4/general/how-to-how-to-flash-factory-image-t2010312
You can download factory images from here https://developers.google.com/android/nexus/images

I have no important data on it.
Which is the safest way to do this? I'd appreciate it if you would be detailed or refer me to a guide, as I want to be careful.

First we should check if you can boot into the bootloader at all. First turn the device off. Then hold down both the volume buttons and then press and hold the power key. Keep holding all the buttons until you see some different colored text. If that happens we should be able to install a factory image, if it still gets stuck on the Google logo I unfortunately don't have any more ideas.
Tried pressing both volume keys and power button. Google logo show for a second, then black for 2 second, thank flashing red notification light every 1/2 second until I let go of the buttons.
When I release the buttons, the phone goes back to charging battery screen.
I see people suggesting that the red light flashing means a battery problem, but the device keeps trying to boot up while it is not plugged to the charger, unlike what happened to them
Any Ideas why this is happening or what the red light means in this case?
You need to press volume down+power button to get into bootloader. Unplug the charger before doing this.

Oh it was just volume down, not both. Heh, sorry.
Use the Nexus Root Toolkit (NRT), it's the easiest way to unlock, root, flash and manage your SuperUser needs!

Not sure, but maybe?
You can try using the nexus root kit & unlock your bootloader and see if a factory reset can work. If it does you can always relock it again ☺..Flashing a factory image can work too also ...
Tried volume down+ power button while unpluged from charger.
Google logo show up with vibration, then goes away after 2 seconds, like before, but then the screen goes blank. But red led not flashing.
What should I do now? Even just to use the Nexus Root Toolkit I have to allow Developer mode, which I can't as the phone will not boot up.

I'm you can't get into the bootloader then I am unfortunately not aware of any way to help you. If you can't even get into the bootloader I think it is a high probability that it is a hardware problem.
I understand. Thank you for your attempt to help me so far, I apriciate it
Anyone else has any Idea what I can try?

First you have to ensure "The Situation" of your phone, diagnostic is very important to decide the kind of medicine or treat. Your N4 booting, stuck on google-logo with red blink, then black screen.
To check : Connect your N4 to PC on linux check on terminal command $ lsusb if output
Bus 001 Device 005: ID 05c6:9008 Qualcomm, Inc. Gobi Wireless Modem (QDL mode),

That sounds like the battery is completely empty. Put the device on charger over a night and try then to boot into the bootloader.
Once I had these symptoms (red light flashing) on my N4, it was enough to charge the battery for one hour. Then it booted properly. It's worth trying.
