You can boot any d*mn thing you please with
Code:
fastboot boot name-of-recovery-image-file.img
so long as you have an unlocked bootloader (and have properly operating drivers on Windoze PCs).
I have been using gapps 20130301-jb on CM10.1 nightlies. (It seems to often report "gapps has stopped", but to no ill effect).

If you have a PC with USB drivers installed it's a very good news for you. I think the best solution for you will be to flash with Nexus Root toolkit with the help of this toolkit you can flash from fast-boot mode.
As far as I know there are so many similar problems and solutions in this forum so if you searched a little you may have got an answer without creating a new thread. Try keeping that in mind for the next time.

Please help.. Thank You

it had pictures.. lol
all the threads on here talk about specific phone models and i wasnt sure so i just went with it... Bad choice on my part..
hopefully someone can help
load up fastboot and try to get to recovery if you can then awesome.. try wiping everything and see if that fixes anything
Pull the battery, hold volume up and power and follow this post to get into recovery. Then like shabby penguin said, when you get into recovery wipe everything and you should be good to go. Again, the post I linked you to is the proper way to root the 4g...

Oh, guess I didnt catch that.
ok your best bet it to go into fastboot and flash the clockworkmod 3.0.2.4
did you do the oem unlock command?
yeah i did the oem unlock.
ok well assuming you followed the directions from this guy, then you have a diff bootimg on there i can toss a few files that may fix it, but no garuntees...
seriously tho
(You should see that “LOCK STATE” says “UNLOCKED”, meaning your Nexus S is rooted.)

is posted on his site.. that would be a good indicator to me to stop listening to anything he said.. he then later in the comments was trying to help someone and told them if usb wasnt working then use a microsd adapter to put the files on..
yeah i am kicking my self in the a$$. Is there anyway do just get it back to stock?
well have you tried flashing a kernel? if it gets to bootani then its usually rom erros, freezing at spalsh screens is generally kernel images
is it possible to load a kernel when i cant see the phones memory from the computer???
someone has to have some idea of to fix this...
just got me to stock unrooted phone.. please
yes, download this
boot into fastboot and type in fastboot flash boot /path/to/natarchy.img
replace /path/to with where its located.. this should get you rollin again
thank you... thank you... thank you!!!!!!!!
i have learned my lesson and i wont stray from the xda forum next time.
Again thank you
I have a similiar issue as OP...I tried to flash netarchy kernel with kernal manager and then phone rebooted and got stuck at google logo.
I have installed SDK...google drivers, but when I try to flash the kernel I get waiting for device in command prompt. Same error when I type "fastboot oem unlock"
Any ideas?

Waiting for device means Windows does not recognize phone. Reinstall drivers.
ok sounds like a driver issue, i used pdanet to install the drivers i needed. try fastboot devices, if it doesnt show anything then your phone isnt connected
Ok used my mac and was able to get cwm recovery on device. I could mount it. Now how can I flash back to stock. I9020A att 3G version. Booting now I see google and a lock.
Thanks everyone!

***WARNING potential brick with OTA 3.5***

If you are on OTA 3 and plan to go to OTA 3.5, make sure your recovery works first!
I attempted to install the old CWM (that didn't work with OTA3) back when I got OTA3 and had forgotten. Since it doesn't work I am stuck with my tablet bootlooping with the "Booting recovery kernel image" message. It just keeps trying to boot into recovery, thanks a lot Lenovo.
Hopefully I can fix this because I think my tablet just went out of warranty, so I can't even try to spin that. (If you know a way to force normal booting, please let me know.)
Also I should note that I have a US tablet. Which is apparently the only region with a locked bootloader. If I could get into nvflash fixing this would be a piece of cake. Now I have to stress out until I can get it fixed because I use it for taking notes in most of my classes.
Exactly same problem here. Will try to flash an update to see if it correct the problem
Hope that CWM recovery 5 works, otherwise will try to install CWMRecovery v6 (again, hope that adb works !)
Yeah, its not getting past the initial bootloader at all, so no Android, which means no ADB. Unless someone knows of a lesser-known button combo for booting into normal mode, I can't think of a way to fix this.
argh, just try to flash OTA 3 (wich should overwrite recovery) but same result ! always reboot on CWM 5.5.0.4
And adb don't seems to be recognize, so not possible to install another CWM recovery
I'm stuck !
Yeah ! solved my problem thanks to koshu (see here)
But I can do this because I had a recovery, so I don't think it will solve your problem David, try to ask Koshu, maybe he can find another way...
I shall ask him! Thanks!

As long as bootloader is viable, you should be fine.
Download the FULL system image from Google:
https://developers.google.com/android/nexus/images#nakasi
Make sure you chose nakasi for WiFi or nakasig for 3G tablet, depending on the one you own.
Download file, extract tgz and extract zip inside of that.
Make sure you have adb/fastboot installed and in your path and that your tablet is connected and recognized. Boot into bootloader mode (which needs to be unlocked). Then do a full flash (you can omit the -w option to prevent the flash from wiping sdcard).
This will restore your device OS back to stock.
Depending on what you did, which you didn't really explain, there is probably a quicker/easier option. But without more info, the only advice I can give you is what I did, which should work fine for all circumstances.
Sticky post above this one is the solution..
It seems like you from your post you used a tool kit and something went wrong or you missed a step. Follow one of the following guides.
I recommend the first one..
Manual adb/fastboot
http://forum.xda-developers.com/showthread.php?t=1907796
Took Kits Automated flashing/ rom install ..
This one is a Windows interface.
......... http://forum.xda-developers.com/showthread.php?t=1766475..........
CMD Interface.
...............http://forum.xda-developers.com/showthread.php?t=1809195..........
I recommend the Manual method But only after reading post in all the threads. This will help you get a better understanding of Android..
Good Luck... the post above mine is also correct if you already have a adb environmental set up
Thank you
Thank you all for your advise
The nexus is once again alive
Have a very happy holiday season

no, you have to get to bootloader, I figured that out, now I'm sutck on "archive does not contain boot.sig" etc..
Hi
I got the same issue....
I can access the fastboot mode and the recovery mode, but not the bootloader. I go back on fastboot mode if I try to load bootloader...
I want to reinstall but windows doesn't recognize my n7 :/ so I'm stuck at this point :/

[Q] Fastboot Reason: Sticky bit factory_fastboot?

I flashed the Eclipse ROM via safestrap and then restored the Eclipse ROM onto the stock ROM slot. For some stupid reason, instead of restoring the stock ROM slot before resetting the phone back to stock, I opted to use RSD Lite 6.1.4 and tried to flash the JB firmware (yes, I got into fastboot). When I tried to do this, the phone reboots past the Motorola M insignia, to the droid startup screen (with the flashing red light/circle), but does not get past the startup screen (yes, I gave it 30+ minutes to no avail). I also tried to reflash the JB firmware, but no matter what, I ended up stuck at the bootup screen.
For this reason, I tried to flash the ICS firmware instead (per instructions on XDA and other websites, I removed the lines in the XML file that had the word var, getvar, and oem). This did work! However, after RSD flashed the firmware, rather than restarting into the OS, the phone reboots into a black screen w/ the phrase "Fastboot Reason: Sticky bit factory_fastboot" at the very bottom. Anytime I try to restart the phone, it automatically boots into this screen. If I hold the volume up and down buttons, together w/ the power button, I am able to get back to the option to start normally.
When I tried to do the OTA JB update, the phone downloads the necessary files, but when the phone tries to reboot to install the OS update, it goes back into that black screen and does not install the update. Also, when I finally do get back into the OS, the phone then constantly reboots as if it were trying to install the OTA JB update.
Does anyone know what "Fastboot Reason: Sticky bit factory_fastboot" means? Also, if anyone knows how to "fix" this issue, I'd greatly appreciate it. If the fix requires command line work (like in this thread), I'd greatly appreciate if someone could walk me through it step-by-step, as I am not familiar w/ the command line process.
Thanks!
Edit 1: The next step I will try is to get root back on my phone, install Safestrap, and see whether I can flash a backup that I previously had.
Edit 2: In some threads for other Moto phones, there is some discussion regarding using ADB to fastboot/flash the stock ROM. Anyone know how this is different from using RSD? Also, can anyone walk me through HOW to ADB? I have zero knowledge in this regard.
Have you tried holding the buttons down to enter fast boot again and reflash? Worth a shot if you haven't. You could also attempt a factory reset from the boot menu. Maybe the corrupt file would correct itself.
You should definitely take the time to learn some ADB; at least a working understanding. It helps down the road.
Here's a good tutorial on ADB commands. http://mobile.tutsplus.com/tutorials/android/android-adb-quick-guide/

Yes, I attempted to reflash on multiple occasions, both using the stock ICS and the stock JB roms. I must have reflashed close to 10x at this point. In any case, no matter how often I have reflahsed (including after doing a factory reset from within the OS as well as from within recovery), I still get the error. The good news is that I was successfully able to flash the JB ROM and have the phone OS actually start up, whereas, a few days ago, it would be stuck at the red circle/eye thing.
Furthermore, I attempted the command fastboot flash system [system.img], and I got the error:
(bootloader) Variable not supported!
target reported max download size of 31457280 bytes
error: cannot load '[system.img]': no error
I saved the system.img in both c:\android, as well as the internal SD card of the phone.
The other good news is that I am still able to use the phone if I get into the boot menu and ask the phone to boot normally. However, I am now unable to get root, and anytime I need to restart the phone, it gives me that error message.
I have also tried the command fastboot reboot bootloader but continue to get the same error message.
OK. Find a JB leak zip or current stock JB zip, access the screen where it asks for AP Fast boot and recovery, choose recovery, then volume up I believe when the phone shows the android with the red exclamation point.. Then choose update with zip. Search your SD card and install. It's worth a try in this manner in case you haven't already.
That's odd that your phone didn't respond well with RSD.

You need to use an updated fastboot binary for the new larger images in these devices.

Skippid, thanks for the suggestions. I tried your method as well. Went into recovery, selected to update from external SD (or something to that effect), selected the JB zip file, and let it flash that way. Unfortunately, I still received the same error message regarding the sticky bit factory_fastboot.

cellzealot, thank you for the link. I've downloaded the file that you linked to. Could you be so kind as to now give me a step-by-step on how to re-attempt the flashing process?
Quick update - I was able to get root back, installed safestrap, and flashed the nandroid that I had made back when I first flashed Eclipse. However, I am still having the same issue:
Whenever I restart the phone, I get the sticky bit factory_fastboot error. If I use the command fastboot continue, the phone boots up as normal; however, it would be great to not have to do this each and every time I reboot the phone. Any help would be greatly appreciated. Thanks!
More updates (still not fixed):
After getting root, I reflashed my nandroid, factory reset (both within the OS and in recovery), and then tried flashing both the ICS and JB stock ROMs. I tried flashing both using mfastboot, as well RSD Lite. The files flash successfully; however, whenever I restart the phone, I continue to get the stick bit factory_fastboot error.
Also, when I get into recovery, I try to flash via "update from external SD". When I do so, recovery simply restarts without flashing the stock ROM.
Here's my last update as to this issue:
After trying all of the methods that I could think of (RSD Lite, flashing via fastboot and mfastboot, flashing from external), the problem did not correct itself.
I brought my phone into a Verizon store, where they told me that they had never seen that problem before. They agreed to replace my phone pursuant to the one-year warranty (I received my phone in December), which I received today. I've again rooted my phone, but have opted to not screw around w/ safestrap and custom ROMs this time around, as I find the stock JB experience to actually be quite good.
Found the soultion!!!!!!
Ok guys so after serching a while I found out similar moto phones have the same issue. I found in a latin forum and in a Droid forum people ponting to the same issue. So the solution that worked for my Razr HD xt925 was:
1) Enter fastboot mode in your phone (very easy since every time you restart the phone you end there anyways)
2) Write this command on the computer: fastboot oem fb_mode_clear
there will be a dialogue with the time take and OK
You are done!
Thought someone might find it useful
Thank you!

[Q] Unsuccessful reflash of Homecare Fly One Note7

Hello guys.
I would like to ask you for help with my bricked Homecare. I apparently cocked up the flashing process and now I don't know, how to proceed.
What I did:
At first I used the Russian (translated) version of supertool designated for Homecare Note 7. But the process wasn't 100 % successful. The bootloader has been unlocked, CWM recovery has been flashed, ROM 4.3 has been flashed. The tablet was able to boot, but it always froze after a few minutes of operation. Most probably there was a wrong boot flashed. No idea.
So, I checked the forums and RootJnky's videos and decided to use CWM to flash a deodex 4.3 stock ROM.
Flash process was successful, but after restart the tablet remains in boot-loop.
Now, I was NEVER able to enter the Recovery or Bootloader using the button combination. Don't ask me why, but it wasn't possible. I could however access recovery or bootloader using ADB.
Right now the only status except a boot-loop is the APX mode. Is there still a chance how to unbrick the tablet???
Thanks for any advice.

At worse case scenario you need to use APX mode to reflash. You can get the download references for the APX files, particularly the package from Advent UK. The package is setup for Windows but it's easy to use in Linux with their executables.
The APX mode does reflash your tablet in whole, but the end result may not be perfect, but should allow a stepping stone to fastboot mode.
If you can obtain 'fastboot' mode then your can reflash partitions. The 'adb' mode in recovery level or system level will allow for updates with 'sideload' command.
Hope that helps.

@e8hfff I managed to sort him out yesterday using the APX method the use has now got it working, with no issues at all (WiFi works as well).
The only thing different for him is that his Generic bootanimation which Xolo Tegra Note 7's have is now showing advent.
I will send you a PM in a bit out the bootanimation as i have a idea LOL.

Hi hacktrix2006.
Thanks for the help again. The tablet is working like dream. All my Chinese colleagues are staring at it. The poor guys know only the products of the fruit company (Apple).
I saw the boot animation is a set of pictures in the flash package from Advent. It is ZIPed.
Is there any way how to make and flash a boot animation without reflashing the whole thing? (I know the answer already, but I don't know how to do it DD)

The bootanimation.zip is in /lbh partition under media. Should be a easy enough to copy and paste in if not then i will have a look for a way of doing it without flashing all of it again.
Docs on Homecare Fly One rom update
Hi jardam.cz AND hacktrix2006
I see you guys have a working method to update the Homecare Fly One - do you have any documentation on how to root and update the rom for this model? Jardam mentioned a Russian rom, but it caused problems. I really don't want to brick this, as I live and breathe with this tablet every day! But I can't stand the limitations of no root.
Almost all the YouTube videos show EVGA solutions, and lots of people have Homecare Fly One problems - what's the solution please?
They are all the same base nvidia model which is p1640 the lbh partition is wrote when flashing via apx mode which can be risky. However there is a twrp recovery for our device and a stock 4.4.2 image from tom you can use to flash a generic version if the os.
