Basically, a bad USB cable was making fastboot operations flakey, and by the time I discovered it, the recovery program was wrecked. Everything else seems to work fine. The Nexus is running 4.2.2, and I have toolkit 4.3.5, running on win7x64.
I've tried reflashing various recovery programs, including the stock one. No error flashing is reported (with the now-good cable), but going into recovery mode fails, showing the android image with a red triangle and exclamation point in it.
[Edit: To be clear, I have NO recovery menu at all - when I select recovery in the bootloader, I get the regular boot "X" in the middle of the screen, then it is replaced with the android lying on its back with the alert notice above it]
The bootloader appears successfully unlocked, and in fact the entire unlock/root process was fine, once the cable was replaced. That is, no errors were reported, everything seems to be ok, but I can't use the recovery option. Note that the unlock wiped all data, so it was as clean as possible.
Should I completely reflash 4.2.2? Will that even matter?
Is there anything else I can try? I'm not keen to try sideloading 4.2.2, but will, if there are instructions some place.
If this is no go, I'm going to have to try restoring everything to the basic original state and asking for a replacement from Amazon. I don't know how that will go, and this was to be a gift due in about a week, that I was setting up for the recipient. I've spent literally 8 hours on this today, before realizing the flakeyness was due to the USB cable being bad. Any help is very appreciated.

So you've tried using fastboot to flash a custom recovery image? The command fastboot is a part of the Android SDK.
fastboot flash recovery <name of recovery .img>
There's plenty of stickies and information in this forum, which I won't re-hash here.
The stock recovery WILL show the android with the red triangle. To get into recovery from there, I believe you need to hold the up volume key. Other recoveries shouldn't do this though. Perhaps you should try using ROM Manager or Goomanager to flash a recovery from within android.
It took several attempts - flashing stock, then cwm, from the toolkit, before cwm finally "took". It's all working now.

Was checking facebook earlier, it stopped responding and just went to a grey screen. Decided to restart the tablet. Now it's stuck in a bootloop and will not turn on. Tried going into recovery but once I select it, the next screen I get is an android with a red triangle/exclamation point. It won't go into recovery and I'm not sure what to do from here. My laptop won't recognize that I have my tablet plugged in either, fwiw.
Is this thread my only option or did I miss something else? This link sounds complicated, but if it's my only option, I guess I'll give it a shot. http://forum.xda-developers.com/showthread.php?t=1907796&highlight=can+t+boot+into+recovery+mode
It can be anything from hw failure to corrupted data. I guess your tablet is stock, without custom recovery or anything. If this is the case, you should try restoring a stock image by that guide or by using a toolkit, like this one. If you have custom recovery on your tab, you should boot into bootloader and reflash the custom recovery with fastboot, this way your data might be saved.
Completely stock. I'll download Wug tonight after work and give it a try since it seems easier than the link I provided.
I didn't back anything up, but that's okay, I can live with that. Just want to be able to use the tablet again.
Well, got home and decided to give recovery another shot. I got it to wipe all data (was pressing the vol up button for too long earlier), but now when i go to reboot the device, it's just stuck on the X screen.
Any advice on what I should do at this point? Should I still try wug?
Hey all, I figured it was time to make a post and see if anyone could help figure out what I'm missing.
So I recently got my G2 and rooted it, then I installed Team Win Recovery Mod (on accident, actually. Was intending to install Clockwork, but figured it wouldn't hurt anything and it was working fine). Anyway, moved on to install Cyanogen Mod and gapps following the usual factory reset -> flash from /sdcard/ approach. Unfortunately on reboot, it went into fastboot mode.
Since then I've read a ton of stuff about fastboot, and I've reflashed recovery, boot, and system a dozen times, but I'm still stuck in fastboot mode. I've grabbed the CWM for LG G2 (AT&T) from http://www.clockworkmod.com/rommanager and the latest stable Cyanogen Mod from http://wiki.cyanogenmod.org/w/D802_Info. Sadly everything I've seen just tells me to do what I did - reflash recovery and tell it to reboot. I've also tried the "volume down + power until logo, then release and re-hit" method of getting into recovery mode, but the logo is present for literally less than a second, so I just end up back in fastboot.
Perhaps I need to find an flash a stock OS first? The thread on returning to stock firmware scares me :/ http://forum.xda-developers.com/showthread.php?t=2432476 Edit: I gave in and tried playing with this anyway. No good, I can't get the phone to enter "download mode", no matter what I do, it reboots into fastboot.
Any ideas?
Edit: The flash method I used for TWRM: http://forum.xda-developers.com/showthread.php?t=2449670
Edit2: This seems possibly relevant. When I do "fastboot devices", I get "? fastboot". So something is wonky in terms of its detection. But all the commands seem to be getting executed fine...
Edit3: Finally a potentially useful piece of info: If I flash the boot image extracted from the Cyanogen mod zip, then run "fastboot continue" I get "ERROR: Getting device tree address failed". Which is the same message I get when trying to remotely run a boot image without flashing it. Possibly related to the "?" in the "fastboot devices" listing above? I switched to Koush's Universal Adb Drivers, but no change.
Pretty please?
I find it hard to believe I could manage to brick a 2 week old phone just by following the guides posted here
Well, I still have no clue what went wrong, but I was finally able to make use of the reset to stock thread. It was strange and scary and at no point did I really have any idea I was hitting the right buttons, and at the end it said it failed... BUT it rebooted me into a fresh install, apparently even unrooted! My problems along the way appear to have entirely been related to actually getting the phone *into* download mode since I couldn't get it to actually turn off. Once it ran itself out of battery and turned off, I was able to enter download mode while reconnecting it to power.
No to decide if I want to try installing a custom ROM again, or take this as a sign...
Who am I kidding. *re-roots phone and pulls up the mod threads*
First, thank you to the mods for putting my last post in the right place (and now I know where the right place is).
Anyhoo, my previous problem was a hardware issue that I've had repaired.
Now, this is no longer critical since I bought a replacement phone (Xperia Z if anyone cares) that is happily rooted and running CM. However, I'd still like the S4 rooted with CM and ready to go in an emergency.
The downside of the repair was that the shop I took it too re-flashed it back to stock (I wasn't happy, but hell, it gives me something to do, practically risk free now). Having soft bricked the I9505 three times, I've brought it back to life. However, I'd like to get twrp on there (Honestly, CWM is stepping backwards rather than forwards IMHO, dumbing down to the lowest common denominator). I have the flash files, and for good measure, I have a stock G4 recovery.
Now my problem,. whilst the phone will boot normally without an issue (I said I brought it back from dead), I can't boot to any recovery, either from the phone itself with HW keys, or via adb. It simply sits there at the Samsung logo pretending to boot. This is with both TWRP and stock, so I'm stumped.
I get the Samsung logo, with the little blue too tiny to read text top left, and there it stays. Normal reboot works just peachy with both. Not rooted as best as I can tell (though it should be). i.e. In developer options, none of the root stuff (enhanced reboot, root options etc.) are missing.
So, whilst not critical (it will still be a handy backup phone), any ideas?
you wouldn't have any advanced reboot options unless they were in the rom, and you can't have TWRP without root. maybe the phone shop left you with nothing as a recovery because they forgot ???
In Odin, uncheck everything except f.reset time, flash the tar version of TWRP in Odin, when you see the word "reset" in the status window, remove USB cable from the phone, remove battery, wait 5 seconds, replace battery, use buttons to get into recovery.
Getting into recovery.
*Press the three button combo of vol.up+home+power button
*As soon as Samsung appears relase the combo and in a jiffy press only the volume up+home button.
Hurray! :')
In order:
I've reflashed TWRP, stock, and CWM - all the successful, but same result
No Odin,. Linux user exclusively - so Heimdall
Three button combo starts recovery reboot (the giveaway is the too small to read blue text top left), but there it hangs. Using abd results in the same.
It simply hangs on booting recovery, whichever recovery, but will boot normally without a problem. Tried with and without SIM/SDCard/both/neither.
Probably worth adding, I'm not new to rooting (done it with my last 7 phones, including the one I'm currently using (Xperia Z)), and the S4 was rooted with CM13 before the shop got their hands on it.
After flashing twrp, are you letting the phone auto reboot from Odin?
How many times. Linux user - no Odin (that's Windows) - Heimdall, and it's not just TWRP, it's stock, TWRP and CWM
Personally, recommend trying to flash with Odin. I use Mac OSX myself.
I only have two options for Odin, either via a VM or using wine, and neither lets it detect the phone in download mode.
However, heimdall has always worked well (previously on this phone) so I'm not convinced that's the problem.
Don't know why, but it's finally worked.
How do I mark solved?
So, about 6mos ago, my Nexus 10 stopped working and I couldn't get it back working...eventually moved onto a new tablet, which now I hate....
Anyway, I figured I'd head back to my N10 because I loved it. However, one of the reasons I left it was because it was stuck in bootloop and I was pretty sure it was bricked.
The bad news, I have followed MANY, if not ALL, of the suggestions on getting it back, I just cannot get it to boot. The good news, fastboot connects with the tablet. So, some specifics:
The tablet WILL boot into fastboot and I can send commands and the tablet is unlocked (also, I believe someone said they had issues because they had an older version of ADB and Fastboot. I'm pretty sure I downloaded the 'most current' version 1.4.3). So, with that, I was able to do the fastboot erase functions, such as cache, userdata, system, etc... and then also load the bootloader (mantafm01) and also send the stock .zip file (image-mantaray-....) and the tablet appears to load everything fine. Thumbs up, right? However, when it reboots it stops at the 'erasing' android bot and will not pass that. I left the tablet in that state for a few minutes all the way up to 3 days...no success.
I also tried the above using Wugfresh only to have the same thing occur. So, basically, I am stuck at 'erasing' and I don't know what to do. I feel confident that the tablet has the ability to be brought back to life, I just cannot figure out how/why all of the attempts lead to the same issue.
What I can also tell you is that while fastboot 'sees' the tablet, the tablet does not appear as a device in "My Computer" like it normally did when connecting via USB. I am using the original USB cable and have tried on multiple computers, all to no avail. I've downloaded/installed the drivers, as instructed on many links. Also, while I can get to the 'Recovery Mode' by pressing Power, Volume Up, Volume Down, if I choose "Recovery Mode" on the tablet, it reboots and goes to the 'erasing' screen. I have tried flashing TWRP on the tablet using fastboot as well. And, sometimes, not all the time, the TWRP blue/black screen appears but it will not progress past that screen (i.e., it doesn't go into recovery).
So, if you can, please help. I believe I have followed all of the instructions, but I have to be missing something or not following something correctly. I'm stoked that it looks like it's only soft-bricked, I just can't get it un-bricked.
Thanks in advance!
Looks like you are trying hard to find a solution. I think it may be helpful if you try to manually install the o/s rather that using Wugfresh and report back any errors. See
https://androidforums.com/threads/guide-how-to-flash-a-nexus-factory-image-manually.706533/ At step 11 I would flash the individual image files and also follow the instructions re erasing and flashing userdata.
AFAIK you will not see an Android device when using Fastboot - Android hasn't loaded at this stage.
Thanks peterk-1. Unfortunately, this does not work. I followed the steps, with the exception of the radio file as my Nexus 10 is wi-fi only. It goes through the stock image update perfectly fine and reboots itself. At that point, it's back to the moving android at the 'erasing' screen.
One thing to note with the link you provided; no where does it indicate flashing a recovery, stock or custom. Now, I've tried flashing stock, TWRP and CWM and none seem to work. TWRP comes closest with the black/blue splash screen, but will not open further.
Any other suggestions would be appreciated.
You did go to the posted link? I quote:
Step 8: We now want to wipe the device. Use the following commands in order:
........
fastboot erase recovery

Step 11: We will now flash the system, boot, and recovery ..........................................
fastboot flash recovery recovery.img
Unfortunately, same result...
I replaced my GNEX10 battery last january. Aside from the battery calibration being off... (which eventually corrected itself!) it's been working fine. As of late it had rebooted itself while I was using it a few times. A few days ago, it had enough battery such that I left it on overnight. I picked it up the next morning and the notification lamp was flashing so I knew it was still on. I tried to wake it up without success. Usually a quick tap on the power button should do it. Nothing. So I rebooted... and on the google logo it stuck. I knew that a factory reset was probably in order since I didn't do it when I replaced the batter... I got it into the recovery screen... but I could not get the menu. I likely didn't press the right volume rocker. Then I tried again... booted to the bootloader, and selected recovery. This time, and since, only the google logo comes up. No andy on his back with "no command". It just tries to boot into something. I can't do a factory reset this way.
I tried the Nexus Root Toolkit. I can only get it to recognize the device if it's in the bootloader... when I try to use it to boot to recovery, same thing and the NRT says waiting for device... and gets no further. I tried to use it to flash (stock?) recovery but the N10 just sits there on the twrp logo screen and nothing more after temporarily booting into twrp. Just keeps saying "waiting for device"
Anyone have any suggestions! Getting seriously bummed!
So one more data point... I manually rebooted into the bootloader after trying to flash the stock recovery using the NRT. Then it appeared to flash the recovery image.... here is the bit of the log where it ended up:
Checking Fastboot Connectivity
fastboot devices
R32CB04GHGT fastboot
+ Fastboot Device Connected
Flashing Stock Recovery to RECOVERY partition...
fastboot flash recovery "C:\usr\NRT\data\Recovery_Stock\recovery_stock_mantaray_5.1.1_LMY49J.img"
Temporarily Booting TWRP...
fastboot boot "C:\usr\NRT\data\Recovery_Custom\TWRP\twrp-3.0.2-0-manta.img"
Flashing 'undo-perm-recovery-signed.zip'...
Waiting for your device...
That's where it ended up... not getting any further. Once again, attempting to boot into recovery gets it stuck on the Google logo.
How screwed am I? Is there a thread somewhere in the forum anyone can point me at?
Well, in spite of the crickets... I understand. I've managed to resurrect my Nexus 10. Alas there are no good contemporary replacements. The last so-called nexus table google put out there was too damn expensive in the first place and they seem to have abandoned the tablet market to others.
So the key question here: So long as I can get this tablet into the bootloader is it generally possible to reflash a stock image? I'd like to know of any types of caveats etc. The mystery I have still though is: How or why did my N10 get into this state (of of only being able to get to the Google screen) in the first place? I didn't have any questionable apps installed etc. I was totally on stock. One thing that did happen a week or two prior to my tablet going belly up... was somehow the thing lost my google account info and gmail had none of my accounts in place... it was very odd.
I did have to wipe the system because evidently you can't flash anything onto a locked bootloader (the Nexus Root Toolkit by wugfresh is up to date so far as the N10 is concerned at least). I know I could have resorted to using fastboot.exe and the adb directly but this was a touch easier. Alas the backup options for it say you need an unlocked bootloader which seems to be a chicken/egg issue if you've always been on stock.... so it goes.
