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.
I have the international/unlocked i9505 and i rooted via cf auto root and flashed the cwm recovery..
I then flashed the ge rom from here and i setup it all nice until I rebooted when it is just stuck at the google animation (with the four colors in the center) and it just stays there. I left it there for a good hour before I put the phone into the cwm recovery and follows steps like wipe the "d" cache and formatting the /system, and /cache. it still boots the animation.. flashed the rom again and it still hung there...Any help would be much appreciated.
EDIT: If possible, i would rather just flash the official touchwiz rom to avoid more problems down the line.

Reflash, and when your phone gives you the option to `fix` recovery, select no. Then let your phone reboot and install.

How long did it hang for? i was having problems reflshing, my phone hung for about 20 minutes before doing anything the first time i flashed it with google rom. I left it came back thinking it was unseccessful and when i was reading for solution it just booted up. Since then i have had no problems reflashing.
Also as above post suggests, in TWRP recovery after i installed a rom when exiting it would say FIX permissions, when i swiped yes the rom wouldnt boot. now it all seems fine however i think i didnt know what i was doing.

Hi guys I've been searching and cant seem to find an answer. My xt907 is rooted and my boot loader is unlocked I'm running CWM. If i install any 4.3 roms they work great for initial boot but as soon as i reboot it hangs at the warning boot loader unlocked screen. And the only way i can get the phone working again is to get to ap fastboot and use the DROID_RAZR_M_Utility_1.20 to factory reset everything. If i flash a 4.2.2 rom i don't have any problems. Any ideas guys ? Ive searched and cant seem to find an answer anywhere. Thanks in advance!
My first flash of 4.3 did this... after that I used twrp and haven't had it happen since...
Sent from my XT907 using xda app-developers app
The latest TWRP+mounting system prior to data/system wipes will probably solve your problems. Also, if you have a backup stored, you shouldn't need to fastboot every time.
I've been having the same problem. I thought it might be because I was using CWM, so I thought I'd give it a go with TWRP 2.323. I made a backup, wiped System, Formatted Data and wiped cache and Dalvik cache and installed [ROM][4.4.1][Official][OSE Rom][XT907].
It installed and booted up fine. After a restart, it hung on the bootloader screen. After booting up into TWRP and restoring the backup, it's still hanging on the bootloader unlocked screen. Doh!
I just reinstalled the new ROM and will hope I don't have to restart while I'm out today. Any ideas on things I can try to get things working?

Okay, I downloaded xt907-twrp-2.6.3.0. In trying to flash with fastboot, it's hanging on <waiting for device>. USB Debugging is enabled and the device is showing up. Thanks for the help!

Fastboot!
Extract the recovery.img from the zip.
But why do that, just flash the zip from your twrp you now have installed

I believe the one that Avi has is a .zip, not a .xml, so it needs to be flashed in recovery. Load it up on your SD, boot into the recovery you have now, flash the new recovery, and then reboot recovery.
TWRP 2.6.3.0 flashed successfully. Unfortunately, that didn't help at all. My phone still froze on the boot screen. I then booted into the new recovery, wiped everything and reinstalled the rom. Now it won't even boot the first time into the ROM, it just freezes on the boot screen. Help!
*EDIT
I just reinstalled it again and formatted data on top of the wipes this time. It booted into the new rom this time, but it did not get past the boot screen after restarting still.

Many people ran into this issue when 4.3 came out and then someone realized that we were forgetting something when wiping. It was something that we did when the BL was first unlocked, but everyone seemed to forget about it. We were forgetting to mount system, prior to performing wipes of the data/caches. Like Avi said, first, I would DL the ROM again and then place it in your SD. When you wipe, do the FDR option first. After that, go into mount and mount system. Then, go into the advanced wipe options and wipe data, system, cache/dalvik, and format data again. At this point, you can install the ROM as normal, don't re-mount system prior to installing, though. When I am done wiping, I always reboot recovery, but you don't have to do that.

Okay, I downloaded the zips again to make sure. This freezing at bootloader screen has happened with every of the dozen or so roms I've tried installing over the past 6 months since I unlocked the bootloader.

Could you clarify a little bit?
1.) Mount system
2.) Wipe (Factory Reset: data, cache, dalvik)
3.) Format data
4.) Install zips
What's the FDR option?

Following the above steps didn't solve it The rom installs fine, boots up for first time normally, but still freezes on the bootloader screen after a restart.
Try geting to the bootloader options & choose normal pwr up.
The new twrp will stick at the big M sometimes.
Then the file is bad or you are missing the install steps. FDR (Factory Data Reset) is the first option you get when you go into the wipe menu, before you go into advanced options. Make sure you're wiping system too, after you mount. If it doesn't work, then it's a bad file or you're still doing something wrong. Upgrading to the most current TWRP and mounting system fixed the issues for 99% of the people. The other 1% just have one of those phones that is "quirky."
okay not sure if your still having this problem. But i never did solve my issue just kept using 4.2.2. But i just flashed the new jbx kernel and a KitKat rom the other along with the newest version on safestrap and i have no issues. Everything flashed and installed perfectly and it boots like a champ. So maybe just skip over 4.3 like i did and see if you still have the issues. Sorry didnt see you were trying to flash 4.4. Only thing i can suggest is make sure you have newest safestrap and wipe out the old etc. But im sure everyone already touched on this stuff before me

Part of your problem is because you are using SS. If you're BL is unlocked, get rid of SS and use CWM or TWRP. SS is not a real recovery replacement, your stock recovery is still there. That's probably part of the reason you had issues.
possibly but i have 0 issues now so its not a big deal.
I have the stable Cyanogenmod 10.1 installed on my phone now. I'm able to restart my phone without any consequences finally. Yay.
I also tried the cm-11-20131221-NIGHTLY-xt907.zip build. That one would initially start up fine, but a restart gave me the frozen bootloader screen. I tried it twice, redownloading it, too. Gah, it's frustrating not being able to try out different roms, but at least I have one that works!
Well, thanks for the help guys. I'd still like to be able to install other roms, so if anyone else has something I can try, I'll do it!
I downloaded Imperium ROM from a thread on xda and installed it. I wiped data, wiped cache and dalvik and installed zip. Then I rebooted and it showed a downloading screen, after a little bit of research it's called download mode or ODIN mode. Now what's happening is whenever I try to reboot, it shows the S4 i9505 screen (i think it's called a splash screen, thats what someone called it) and freezes. After about 10-15 seconds, reboots into recovery. I've got CWM installed and I've ran out of ideas. The volume buttons are not being touched and for some reason recovery and download mode are always being booted into, never the OS.
I'm also new so anything I've done wrong, I'd love to know.
CWM recovery is outdated and should not be used anymore. Instead only use TWRP. Flash it trough Odin in the same way you flashed CWM.
You say that you only wiped data, cache and dalvik. You also HAVE to wipe /system. Otherwise the rom will probably not boot.

Update I tried to install albe95's s6 port. I've noticed something and it's that both ended up with Statuc 7 or some word that started with "S" and had the number 7. Googled that and turns out it's bad. I formatted /System and installed the ROM, it worked!
I guess there was just no OS to boot into. Going to try installing Imperium now.
Status 7 errors can occur if the recovery is outdated. What recovery is on the phone?
