UPDATE: After completely wiping everything(recovery, ROM, bootloader, etc), and putting it back in with fastboot I no longer have this problem. My recovery probably just got corrupted or something while getting sent over to the device.
Got my Nexus 7 3 days ago, had it unlocked and all that jazz within the hour(thanks to the people who put the stuff together). It's great, but I have a problem with flashing .zip files in recovery. It doesn't matter what type of thing I'm wanting to flash(ex-kernel,rom, or even the uber-simple 720p camera mod), if I don't do a full wipe before flashing, then it just ends up boot looping my device. The boot loop doesn't turn the phone all the way off, just the boot animation. Sometimes the launcher will pop up for half a second and then go back to the boot animation.
For example, whenever I flashed the rasbeanjelly rom, I first flashed that, then rebooted(got excited and forgot about gapps) and checked it out. Remembering about gapps, I went back to recovery and flashed gapps. Then it boot looped the animation. After flashing gapps again(trying different combos of wiping cache/davlik), I flashed the rasbeanjelly rom again, and then gapps immediately afterwards. Still a bootloop. So I did a full wipe(including data this time), sideloaded my .zips, and then it flashed and rasbeanjelly booted up with gapps just fine.
This exact same problem has been happening with every .zip that I try to flash(running TWRP, yes all my stuff is updated). If I want to flash a kernel, I have to flash it when I flash my ROM or else I'll get boot loop. I can't really make any modifications without having to completely wipe my device(which is annoying because I carry a lot of data around on my stuff)
I'm asking if there is a way to flash a .zip without having to completely wipe my device. I'm not a noob to android at all(ROM cooker over at androidforums), but I can't figure it out, I'd love to make stuff for the grouper but this is kind of a big roadblock for me. Logcat isn't helping either. Hopefully I just skimmed over something and it's a simple fix. Thank you for your tips/suggestions/solutions.
EDIT: forgot to mention something. When I flash a new ROM and get it going, I always make a full backup in recovery. If I flash something, and boot loop it, I can't restore it correctly. Recovery says that it restores all good, but it still boot loops(even though I just restored a backup of a non-boot looping system from no more than 5 minutes ago).
If I read your post correctly, you've only tried this on one ROM. Try the same thing on CM10 or PA or whatever you want.

I've actually used several, and it seems to be happening on all of them. I've tried flashing things with PA, CM10, Stock, and RasberryJelly. The kernels I have attempted to flash have been Trinity, Motley, and Franco. All with no success and boot looping me :/
OK, this mat have been asked many time, but none of the thread I found applies to my case.
My device is Nexus 7 16Gb Wifi, the internal ROM is stock 4.1.2 (I cannot use 4.2.2 because of a backward compatibility issue for an app I have to use)
The recovery is the latest TWRP 20030227 version, with MultiROM bootloader 4.18. An armhf raring build of Ubuntu is also installed in the internal sdcard and all have worked fine until I tried to flash a alternative kernel.
The new kernel I flashed is the M-kernel mr1.1. I flashed it by booting into recovery and chose to install the M-kernels zip file from there. After I have got a kernel flash successful message I chose to reboot system. Then the weird thing began: at first the device seems to be booting because I saw the usual Google logo and then it turned into the boot animation with a colorful cross in the middle of the screen. But then on nothing seems to follow. The boot animation persists forever. I hve also noticed that during the initial boot it somehow skipped the step of choosing ROMs as usual (because I have Ubunto installed), so I also lost the choice of booting into Ubuntu.
I have to press the power button for more than 10 seconds to power off the device. Then I tried to boot into fastboot mode and recovery mode, both works file, so it still looks not bad. I have kept a copy of my working patched kernel which is kernel_kexec_41-2.zip. Booting into recovery and using the command
adb push kernel_kexec_41-2.zip /sdcard/
I managed to copy this zip into the device. Then, once again, I tried to flash this old kernel by installing it in the recovery. The installation exited with a success. However, when I tried to reboot the device, it is still stuck on the boot animation screen. No choose ROM screen either. So, I am totally lost. Can anybody give some hint on where I was doing wrong and how can I get my device working again without totally reflashing a stock rom and loosing all data I have installed previously? Many thanks.
Any helps please.
Let me update the situation. Tried to wipe cache/Dalvik and reflash the kernels (both the original and the newly downloaded omega3 kernel, both changed nothing -- always stuck in the boot animation. Tried MultiROM->Advanced->Inject curr.boot.sector, the screen allowing to choose rom reappeared and from there Ubuntu boots correctly. However, If the internal ROM is chosen in that screen, the device reboots and stuck in the boot animation screen again.
How about if you make a backup?
Then - no matter what follows - no matter what experiments you do - you can always restore just the /data partition. Or any of the other partitions.
Frankly, you should have done it already, but nothing is stopping you from doing it now.
Backups give you power - and freedom - to experiment with very few risks.
good luck.
Thanks! I didn't realize that I can still make a backup even the system is already broken. Did the backup for the data partition and reflashed the stock rom, it now boots ok. Even though I still lost the desktop configuration and the Ubuntu installation.

Had it happened that you still had a bootloop after dirty-flashing /system and/or boot (without doing the custom recovery "factory reset" wipe of /data exclusive of /data/media), a backup can still save your bacon: it can be restored and then manually:
- all system app related /data/data/ and /data/app-lib/ folders removed
- all system app updated .apks in /data/app/ deleted
- wipe dalvik-cache
This leaves all market apps and their data intact while starting from scratch from with the base ROM's system apps. Probably doing that reduces the chances of boot loops.
UID mismatch troubles can still occur if you are coming from a "debloated" ROM and dirty-flashing something like a stock ROM (where there are more system apps than in the prior ROM which generated the /data partition); but I think that TWRP's "fix permissions" should take care of that.
But anyway - backups give you flexibility.
I know it has been asked before, and I have searched the threads. reverting to stock is not a problem.
nexus 7 grouper when installing a custom rom (liquid smooth v2.9 specifically) I get stuck on the liquid boot image.
I have successfully installed v2.7 and am able to revert back to stock or custom.
after a data format, factory reset, and wiping all caches, installing the zip file from abd sideload, or directly from the device the new rom that has flashed will not get past the boot image. am I doing something wrong, or could I do something differently so that the new v2.9 boots up correctly?
I know it has been asked, but the most common answer is to go back to stock. okay, I get that. but I know this rom will run (it is flawless on my s3,) but I cant seem to get it working on the nexus.
thank you.

There have been numerous reports of bootup problems with "clean" LiquidSmooth ROMs in v2.7, 2.8 and 2.9.
Some possible solutions are:
Dirty flash on top of a LS ROM that boots (for instance dirty flash 2.9 on top of 2.7). When doing this you DON'T clear data and cache, but flashes new rom directly, along with gapps and kernel, and boots up. This has worked for some.
Another option when you get stuck on boot screen is to boot into recovery, and do factory reset and clear caches one more time, and try to reboot. It might take several times booting into recovery, and clear data/caches before it boots up, but again this has worked for some.
Finally you could also try the order in which you flash stuff. For instance try ONLY flashing rom, then reboot. If it works, then flash gapps. If it gets stuck, try flashing both rom and gapps in recovery, then reboot etc.
Hope that gives you something to play with! And I'm pretty sure that if you're insistent enough, you will eventually get it to boot! :good:

I will keep trying. getting liquid to run on the fascinate was curious as well, but after a few flashes it took. I'll keep trying on the nexus.
Update: yes, persistence is the key. thanks
What I did was from v2.8 a factory reset, wipe cache and dalvik and flash from sideload
as expected it boot looped. manually booted into fastboot and flashed v2.9 again with only a cache and dalvik wipe.
this time it booted and I flashed gapps.
at the reboot I set up the rom to my liking and it seems to boot normally now.

Yes, after it boots through the first time, I've only seen it boot normal from that point on.
Simply put, this is what happens when a rooting newbie discovers custom bootloaders and ROMs.
Current State:
A full stock ROM installed (no root) with the Skrillax V8 bootloader plopped on top of it. (which of course means the recovery-from-boot.p file still exists and that I don't have CWM.) The tablet will show the Acer logo then the Android logo and will give the appearance of booting. Then the icon flashes. It does this intermittently and forever.
What I want:
CM 10+ running with Skrillax and TWRP stably. I'd go with Flexreaper for next choice. Maybe I'll try to compile a KitKat version for it someday. Who knows.
How I managed to get my tablet in this crappy state:
Rooted tab a long while ago with a probably far outdated method.
Looked all over the internet later on how to unlock the bootloader and settled on the manual method in this excellent thread.
I flashed V8 and TWRP without a hitch using nvflash.
I wiped and installed Flexreaper.
I liked it but wanted a higher prize. I make a nandroid backup of it onto the external_sd and wiped and installed CM 10.1 from this thread.
This is where everything started going sour. It told me the install was invalid halfway. Disappointed, I wiped again and tried to restore my nandroid backup. It seemed to restore properly, but then Skrillax hung forever loading the kernel.
I wiped again and installed Flexreaper fresh. This time it booted. I downloaded the newest unofficial version of CM they mention on their wiki.
Booted to recovery and installed CM 10. It ran fine and I was impressed with the new OS. Then I noticed the apparent lack of Gapps.
I flashed the Gapps Jellybean package and rebooted. Skrillax hung.
Wiped everything I could fine in the TWRP menu and installed Flexreaper. Got past the primary kernel loading but the android icon would work for a bit then flash, starting all over again.
At this point I flashed several other recoveries, hoping it was my recovery. No such luck. I tried all of them included in V8.
Then finally, I downloaded full stock ICS and flashed it. I rebooted and noticed the same Android flashing thing.
Finally, I flashed V8 again, being the newbie I was, and then suddenly remembered while trying to boot to recovery that the Full install probably rewrote the recovery-from-boot.p.
And here I am.
Tl;dr version:
Went click-happy with ROMs, wiping, and recovery flashing until I was left with a stock OS that wouldn't boot with a Skrillax bootloader but no recovery.
The good news is, I still have cpuid+sbk, it still boots to APX (no idea how I didn't screw that up too.), and I have a nandroid backup on my external_sd which is probably untouched, since I was careful to not wipe it in TWRP.
Please help me fix this. I don't want an excuse to waste money on a flashy new Nexus or Asus Transformer tablet, I already have too many for my wallet's comfort.
I quess you renamed stock rom to update.zip and than flashed it? If you havent do it, put it on sd card and pres power+vol down (if nuttin happens than vol up). That shld trigger flashing proces

I don't have access to a micro sd card reader if the file must be placed on the micro SD card. I already have flashed the stock rom supposedly via TWRP, so I shouldn't have to flash it again, I wouldn't think. If I do, I guess I'll have to get a reader.
Yes. Micro sd. Rename it. You have guodes gere on xda. Im hoping it will help you.

It didn't work. Still in same state as before.
I also have access to fastboot if that would help.

Babsector should still work - you would need t do a search for it
It seems to have worked properly, sort of. Flashing FLEXReaper results in an "Encryption failed." prompt at boot, which the button, of course, does not work. Wiping everything works except that the prompt notes "E:format_volume: make_extf4fs failed on /dev/block/mmcblk0p4" Trying to reflash V8 with TWRP with the V8.bat file fails at format. More help?
My tablet is still displaying "Encryption failed", the button still doesn't work, and I still love my a500. Help?
Anyone?
I guess I'm screwed, then.
In the end, I think my data partition failed. Formatting or wiping data fails and when installing FlexReaper, it reports /data size as -1. Unless anyone knows how to fix flash memory, I think I'm stuck.
Hi folks,
I recently rooted by N4. It was running Android 5.0.
I also have MultiROM installed, with CyanogenMod installed as a secondary ROM.
I didn't realise I couldn't apply the OTA updates to the stock Android system (my oversight), and I allowed the device to download and (attempt an) the recent 5.0.1 update from Google.
When the update attempted to reboot the device, I could see in the terminal data that popped up, that it failed.
After that device now gets stuck in the booting stage with the little coloured balls drifting around.
I continued to use my phone with the secondary ROM (Cyanogen) for some days until I had time to sort this out.
MY ATTEMPTED RECOVERY
I read that ordinarily on a rooted device one would manually apply the various image files from the full 5.0.1 package.
So, following instructions found here: http://forum.xda-developers.com/nexus-6/general/guide-flash-factory-images-nexus-6shamu-t2954008
Using method two (long method).
... In fastboot mode I flashed the system, boot, recovery, cache (after clearing cache), radio images from the 5.0.1 stock image.
At first I didn't flash the bootloader (as I wanted to maintain the multiboot loader I had installed) nor the user.img (I don't want to lose my user data). I read this should work. But it didn't.
When it came to booting into recovery mode to finish the process, an android icon with a ! warning on it would appear, and I could not do the recovery.
So, I have since flashed the bootloader also. That didn't change much, except that my dual-boot boot loader is now gone, and the device is still not recoverable.
Is there something I am not doing correctly? How can I recover this device so that it has 5.0.1, my existing user data, and my existing dual boot bootloader?
Cheers,...
May have solved it...
I'll post another update in a moment. Posting this just in case someone starts responding to my question in the interim.
After further fiddling around, I may have resolved this issue. I've managed to get it into recovery menu, rebooted from there, and device is now in "Android is updating" mode. Looking good.
Will post new message soon as to whether this was successful or not.
Issues continue
So, after the device booted a screen appeared for a fraction of a second, that appeared to be the screen for selecting system language (as per what happens when a device is first run after a clean install). But the screen almost instantly goes black except for the little network icon and battery icon and time in the top right of the screen.
If I use the power button to lock the screen and again to activate it, the screen very briefly flashed up the language selector, then goes blank again.
So... it seems something odd is happening after applying the 5.0.1 file.
Any suggestions?

Well, this is what I resorted to doing. And it worked. Phone started and was as new. Of course, I lost my user data which is a ****. I did pull the SDCARD content over ADB, but am not sure how I'd go about pushing it all back on, into right locations, etc.
BUT—and it's a BIG BUT—when I re-rooted it and applied SuperSu, it couldn't be put into recovery mode any more. It would keep running through the SuperSu install process each time I'd attempt to go into Recovery.
I ended up ignoring this, and installing Busybox (with Play) and SuperSu.apk (via Play). But the SuperSU apk would keep saying its files needed to be installed/updated.
I forget the exact mess that unfolded, but eventually (after installing MultiROM) I could boot the phone as it would ALWAYS go into (custom) recovery.
So I starter the whole process again, with another clean install of 5.0.1, and yet now it is stuck at the bootloader (the little swirling balls screen).

Try a full wipe from Factory Recovery, and see if it will fix the bootloop.
Bootloop no more...

After many tedious hours of messing around with this beast... there is life beyond the bootloop.
Back to a stock install.
So, now I am wondering why the SuperSu/Root process didn't work on my last round on this.
The SuperSu installer would kick in EVERY time I went into Recovery mode, and would then reboot the phone. This made it impossible to do things with ADP because I essentially couldn't get into recovery mode. I wanted to push through some of the stuff I pulled using ADP before I wiped the phone previously.
I installed MultiROM (which includes TWRP [is that what it's called] recovery system. BUT then go stuck in a Recovery loop.
Not wishing to repeat that fiasco... does anyone more knowledgeable than I (not a difficult status to achieve) have any suggestions to what might have caused those issues?
