Flashing Rom always ends in boot loop?

I have had my N7 for a week now, and have unlocked and rooted it. I flashed the jr5 rom and it worked ok, but i decided I wanted to try the pure AOSP rom, so I did a data/cache/dalvik wipe and flashed the rom. It proceeded to boot and freeze at the Google screen. I rebooted into recovery, and attempted to restore from my backup (failed), flash the jr5 rom (failed), and reflash the AOSP rom (failed). I then decided to follow the instructions on ROOTZwiki and restore back to stock (although still unlocked). I restored to the factory image, and attempted to flash the CM10 AOKP rom, and was again met with the frozen Google screen. I made sure to wipe data and both caches each time i tried to flash a rom, but I always end up stuck at the Google screen. What could be causing this? I would really like to know if anyone has any idea, because I fully plan on running the full version of CM10 when it is released.

By wipe Data you did factory reset in cwm? And what version of cwm are you using?

yes i did a factory data reset each time. I am currently running v5.8.0.2 of cwm

could that be the problem? that my cwm is just outdated already?

No that shouldn't be causing your problems, although I would recommend flashing TWRP recovery through goo manager.
I would first download a ROM on your computer and check the MD5. Then mount your nexus over USB and copy the new ROM over to the nexus sdcard directory and while its connected use your computer to check the MD5 on your ROM while its on the device. Then wipe data, cache, dalvic cache and system. Then install the ROM and Gapps and reboot. Make sure its only the to, and not a desperate kernel or anything for right now. When you reboot give it 10 minutes or so the first boots are often way long.
If that doesn't do it copy the stuff on your SD card over to your computer and then format the SD card.
To install TWRP, install goo manager from the play store, when you open the app just press menu, you don't need to browse for files or anything. Just press menu and then choose Install OpenRecoveryScript and when its done reboot or reboot to recovery, can't remember which did the trick, and it may take a couple of times.
Also remember that booting through boot loader to recovery requires the USB cord to be connected to a computer to avoid the Google screen looping.
Hope some of this was helpful.

Thank you for taking the time to help me. Before I do the goo-manager/twrp install, are there any inherent advantages or disadvantages of using twrp as opposed to cwm? Also, I hadn't thought to check md5s after moving the roms, so I will be doing that from now on.

Twrp works just fine.
In your recovery, can you mount and unmount all your partitions without any errors?

am I finally doing it right?
I flashed EOS rom from a clean system and it worked fine. Decided to have gapps and installed via twrp. This would give me boot loop into recovery no matter wat combination of cache clearing etc used. So finally I did the counter intuitive and installed gapps zip followed by ROM zip. This seems to have worked though it seems backwards to me. Is this the correct procedure?

no. did the rom already come with gapps? the rom would wipe out whatever gapps you did flash before the rom.

I don't like Twrp not being able to boot into recovery from holding the buttons, especially running into these loops during installs. Had the sameresults with cwm though.Now I am having this boot loop with TeamEOS as well as Skanky (neither package gapps) I however only loop if installing gapps after the rom or wiping caches.
If caches and system are wiped, gapps installed, then the rom I get a functioning system.Can anyone shed some light on what trigers specific loops or how to review tje errors / panics?

I'm reviving this thread since I have a similar issue. I am using TWRP. I have no problem performing a wipe (I do a factory reset, plus dalvik cache wipe), or flashing a new ROM (I've tried SGT7 and PA2.11). I can boot into the ROM fine. Once I try to flash Gapps, I get stuck in a boot loop that ends up going back to recovery. I've tried different combinations of operations, with different versions of gapps, but nothing works. I've tried:
gapps-jb-20120719-signed
gapps-jb-20120726-signed
both from goo.im, MD5 checked, without success. I'm stuck using SGT7, because that one includes Google account, and Play Store, so that can get me going... Only thing, I haven't wiped the data partition, because that's a bigger hassle. Do you guys have any clues as to what I should try next?

Do you flash the rom and gapps and then reboot, or flash the rom, reboot, then flash gapps?

Did anybody get out of their bootloop? I flashed paranoid droid with twrp and I didn't select "signature verification" or "md5 check" as I read before hand on another forum that it wasn't needed and to actually not tick "signature"....so now I'm in a bootloop, volume buttons and power does get me in to a few selections, "reboot", "power off" and "recovery". When I select recovery it just takes me to the black screen with "Google" on it. No idea how to get out of this loop....I'm researching now but I am not understanding much....I'm so use to Samsung devices, getting out of bootloop with those are a piece of cake, this I'm clueless and helpless on. So does anybody have a way for me to either reflash the rom or get me to where I can go back to stock? I used wugfresh to root. Thanks.

[Q] Data not wiping and cannot flash rom

Hi guys
Im currently using Energy rom on romslot1 aa daily rom. I downloaded tripping bean and was trying to install on the stock rom slot. I did factory reset cache wipe dalvik cache wipe and system wipe. But when i tried to install the rom Im getting an error " set_perm - some changes failed " status 7 error ... googled it out and it said to try downloading the rom again. but i downloaded again and did md5 check and it was same and installing still not working. not sure whats wrong. Also i tried to wipe data but im getting an error unable to wipe data. Im guessing somehow these two errors are related?

You need to get into fastboot mode but first download Matt's utility 1.20 and follow the interactions.
http://forum.xda-developers.com/showthread.php?t=2249773
to get into AP fastboot mode turn off you're device and hold power+ vol up + vol down and then when you get to a black and white screen use vol down to navigate, scroll down to where it says AP fastboot and press vol up
in Matt's utility it gives you the options to flash stock 4.1.2 in fastboot mode.
it's option 1 I think.
if you decide the option to root you has to be in USB debugging. (phone needs to be booted up)
it would be nice if you unlocked you're device's bootloader, and Flash TWRP recovery. it's a better option than safestrap now anyways good luck.

Do not use utility version 1.20, unless you have updated to 4.1.2. You will have issues. If you have not updated, you need to use utility version 1.10.

Thanks man. So much to do i guess. But I have a doubt. If I flash stock in fastboot mode using the utility, do i lose the safestrap and the slots and roms in it. I mean if i do this it will be like brand new? and unrooted?

I did see your post afterwards. But I havent started doing it because I will lose all my roms n data if i do it. I had got my razr m on 4.1.1 and then i had rooted and installed safestrap and had flashed several roms on the stock slot also. So the rom in the stock slot is 4.1.2. But I cant boot into it. The rom in rom slot 1 (my daily rom) is 4.1.1. So can i use utility 1.20? or should i use 1.10? Whats the difference?

If you updated to official Verizon update in stock slot (4.1.2), then you need to use utility 1.20. 1.20 is designed for 4.1.2 and it includes all the fastboot files for 4.1.2. The key here is whether or not you flashed the official update. There are only a couple of 4.1.2 based aftermarket ROMs available, and they're over on DroidRzr.com (cm10.1 doesn't count because it's not a stock based build). If you didn't take the Verizon update and didn't flash any of MHouse's DST or FXZ ROMs, then you should still be on 4.1.1. If you are on 4.1.1, then use the utility version 1.10. Honestly, you just need to get over the fact you're going to lose ROMs and data, and fastboot the phone back to stock. Then, start from scratch. If you have any important data, save it to your external SD or computer. You'll be able to flash everything again, once you have a good, clean stock install. Then, after fastbooting, unlock your bootloader and stop dealing with SafeStrap. Install a custom recovery, and flash until your heart's content.

Yeah my bad, I didn't know it could cause issues. Anyway, it doesn't matter if you lose safestrap because right now unlocking your bootloader and flashing a custom recovery is safer, lol. if you do decide to install a custom recovery make sure you backup you're stock ROM.

If you don't wanna lose your roms and stiff back up with ss and put it on so doesn't take but about 10 mixtures after fastbooting to go back the way it was

[Q] Nexus 4 problems.

I'm having a big problem with my Nexus 4 here lately. I tried to root it about 2 days ago, and it did not work. So i downloaded TWRP and my computer read it the same as the Nexus 4 root toolkit by WugFresh. I opened TWRP and it asked me to flash or boot (it was on flash), and i think i clicked "Recovery" and it made my Nexus not boot up, it was just at the logo screen. Then i tried to flash TWRP to the bootloader and System and it flashed TWRP, now it won't go into android. It just takes me into the TWRP interface. In the TRWP interface there are 8 options( Install, Wipe, Backup, Restore, Mount, Settings, Advanced, and Reboot). I pressed "Reboot" and i when press System, Recovery, or Bootloader it tells me that the is no OS installed, I've looked up how to install OS back via WugFresh's toolkit, but it's still not working (maybe because I'm on a old computer). So I'm kinda panicking, is there anyone i can call,or take my phone to, or can you guys help PLEASE!?!

1. Calm down, dont panic. Its an easy fix. You need to push a rom onto your phone using adb, then flash it using twrp.
2. Setup adb.
3. Download ROM: here or here.
4. Use this command to copy the rom to the phone:
Code:
adb push nameofROM.zip /sdcard
5. In TWRP go to Install, look for the rom you pushed, select it, and finally swipe to flash it.

Okay, i'll try that right now..

Thats the stock recovery, but since you have TWRP installed that is your current recovery. So go into TWRP and use the command from there.

On the first boot after flashing a new ROM the Nexus should start up within 5 to 10 minutes. If the phone is still displaying the boot animation, reboot into the phone into TWRP recovery, select Wipe, select Factory Reset, wipe Cache and Dalvik cache, and reboot the phone.

Thanks! I think it was just the ROM i chose. I just downloaded Slim Bean, this seems to be working( the startup screen looks cool ) I'm on the "Android is upgrading..." screen and it says "Starting apps." at the moment.

Okay, SlimBean took more than 10 minutes, so i factory reset and tried again, and it's still not booting up. ):

I have not used Slim Bean. It sounds as though you got past the boot animation screen to Slim Bean updating apps (Android upgrading). Normally ROMs that update apps on startup display a count as they update. Does Slim Bean display such an update counter? Does the count progress or does it hang at some point? Note that the system update on startup will take additional time depending on the quality of your phone's network connection. If you are still experiencing issues with Slim Bean, I recommend that you post on the developers forum where you downloaded the ROM.

It is certainly more convenient to replace the stock recovery with TWRP permanently since this gives you more freedom when installing ROMs and performing nandroid backups.
I would try booting into TWRP again, install the Slim Bean ROM one more time, install Gapps, wipe Cache and Dalvik cache, and reboot your phone. If the Nexus gets past the boot animation to "Android upgrading" allow the upgrade to complete. If you are still having problems with Slim Bean, I suggest posting your question in the Slim Bean thread in the developers forum.

After flashing it, did you go into the stock recovery to factory wipe data before booting it up? You have to do this or else you will get stuck at the Nexus bootup screen. Happened to me once. Apparently you have to do this on the Nexus 5 and Nexus 7 because flashing it doesn't properly wipe the partition.

Hloo m.charesa,of course I wipe data,partition after flashing many times(I watched the clip in youtube does that),But unfortunately due to the nexus logo.

It seems that the problem is not to activate the USB debugging , because after opening bootloader or installing stock rom returns the device to its origin and must be activate (usb debugging) again .. Question: Is there a way to activate it without the operation the system (because its not operation originally)??​

USB Debugging is only necessary if you are trying to use ADB when the phone is on and booted into the OS already. It's not necessary when you are in Fastboot mode (at the bootloader). Not sure why it's not working flashing the factory image. This is why I prefer not to use toolkits and do everything manually. That way, you know where things went wrong.

[Q] Help Please!

Hey guys! I'm not a developer. I unlocked the bootloader of my Nexus 4 and rooted it. Along with that i even installed a matrix kernel. So now what happened is my phone wouldn't display anything after starting up but it was connecting to my PC as i had enabled USB debugging mode. But as the phone wasn't starting, i formatted everything except the sd card, cleared the cache and dalvik cache and reinstalled the franco kernel. Even that didn't start so i downloaded CM 11 nightly version and tried to install it, but it didn't get installed. I installed the matrix kernel again and tried to install CM 11 but even then it didn't get installed. Now my phone is stuck on the google logo and the only thing i can do is go to the bootloader, recovery etc. but I can't connect it to my PC as i had factory reset it, the USB debugging had stopped. Basically i just need help in figuring out what should i do. I'm ready to have my phone back to its stock settings and i'm even ready to keep my phone rooted. I just need a way for it to start working. Please guys!! Some help here!!

Don't panic. The first thing you need to do is flash the factory image in fastboot. After you get your phone back then you need to read a lot before you flash anything again

Relax!
Download the Nexus 4 factory image from Google and flash it using fastboot from your PC.
This will revert the phone to pure stock unrooted settings and then just try rooting the phone again from there.
Check of your kernel and ROM files were proper, if they were corrupted then it could have lead to the bootloop

Hey! Thanks for the help but the USB debugging mode in my phone is switched off as i had reset it. So basically i can't connect it to my PC.
It shows under device manager etc but doesn't show in My Computer. I'm running Windows 8 64 bit.

And by the way, I downloaded CM11 Nightly but it couln't get installed due to some error and before installing the ROM i installed the matrix kernel but after installing, the phone didn't start. It showed the starting animation but did not start the phone up. Can you please tell me how to enable USB Debugging from CWM Recovery? Coz it's stuck on the Google logo and i can't start it, so neither can I enable the USB debugging mode.

Is your recovery up to date? If not please flash the latest one or flash trwp recovery instead. Use adb sideload, since you cant access your usb debugging

You don't need USB debugging for fastboot. Download the factory stuff from google, turn off device, hold volume down and boot up device (i.e. into bootloader), and run the "flash-all.bat" (after extracting the downloaded file) .. This will wipe your data. If you want to keep data, open the flash-all.bat file and remove the "-w" from the last line.
