Installed cutom rom now stuck on google screen :(

Ive checked other nexus 7 threads... but this isn't the case.
My nexus 7 is stuck on the google Boot I cannot rub Fastboot or recovery from the toolkit .. nothing at all. It cant find the device .
When I plug in the usb it still makes the sound on windows and so on.
It happened when I was prepairing to install a Custom ROM using JROMFlasher..
I followed all the steps, and when it came to install the ROM to the SD card it just rebooted (transferred to quickly I thought)
And then Ever since it has Just been stuck on the google screen.
I am quite pissed :L
Any Ideas?

I would be quite pissed at your self for using a toolkit. this is a Nexus device and is easily unlocked manually with the proper tools that google provides themselves. Boot into fastboot mode (Hold Power and the two volume keys). Once in fastboot mode you can flash a recovery and then once in recovery you can adb push a ROM to the tablet and flash the ROM the correct way. You really should read up on how to do thing manually instead of resorting to the quick and easy method.
Download the zip located here : platform-tools.zip Extract the contents to a folder name the folder Nexus7 or whatever you want.
Once thats done go ahead and open a command prompt window in that folder you can do that by Shift+Right clicking inside the folder and selecting "Open Command Prompt Here" or if on XP then open CMD and
Code:
cd C:\Users\Name-of-User\Desktop\Nexus7
Once in the CMD issue the command
Code:
fastboot devices
To see if the computer recognizes the device in fastboot mode. It should spit out a gibberish looking code with ....... Device at the end.
Then you going to flash the recovery to do that you issue this command
Code:
fastboot flash recovery name-of-recovery.img
inside the zip the openrecovery-twrp-2.3.1.0.img that is what you will put in place of "name-of-recovery.img" it will show on the screen writing recovery when its done hit the volume up button until the "START" Turn to "Recovery Mode." Then hit the power button you will boot into recovery mode. Once in recovery mode place the ROM.zip you want to flash in the same folder as the stuff you extracted to.
Then issue this command
Code:
adb push Name-of-ROM.zip /data/media
Of course you will replace name-of-ROM.zip with the actual name of the ROM you are flashing. Make sure you also have a gapps packaged which can be found on goo.im/gapps/ latest package is gapps-jb-20121011-signed.zip you will want to adb push that as well.
IF all is done correctly you should be able to install that ROM please follow this procedure.
1. Go to Wipe
2. Factory Reset (this will delete all your apps and apps data not the sd card)
3.Wipe Cache Partition
4. Wipe Dalvik Cache
5. Format System
6. Go to install and find the two ROM.zip and Gapps package at the bottom of the root of the sd card (/sdcard0)
7. Select to flash the ROM and then the Gapps
8. Reboot

Not really necessary but alright. remember going back to stock deletes the entire tablet memory So make sure to back up your important data.

It was formatted anyway there was no Important data .. Actually you maybe able to answer something for me.
When I rooted my Nexus before all this.. It was rooted as I done previous tests.
What do you use to move files to and from the tablet such as root files? As I want to modify the "X" boot logo animation. I noticed it is just a bunch of PNG images that need replacing..

Acutally its a zip of multiple components not just png's. The bootaniamtion.zip as a whole is what makes up that boot up animation. If you want to change the bootanimation you would replace that entire zip with one that you want. And then set the permissions and reboot. Some will even have a flashable. In order to modify system files you need root and a root explorer. There are multiple on the play store i would recommend Root Explorer if you have the money otherwise ES File Manager or Solid Explorer.

Bricked after wiping with twc
When I look for fastboot devices, nothing happens...
where do I go from here?

[Q] phone won't boot....please help!

Last night I was using my Nexus 4 and it wouldn't connect to any web pages so I thought I'd reboot to see if that fixed it. I powered off then back on and it won't get past the Nexus logo on the start up screen.
I'm unlocked and rooted but haven't installed any Roms ever. I used Wug's toolkit to root.
the only thing I can think of is that I was copying fonts from the system folder and maybe I moved a font instead of copying it, but I really don't think moved anything without replacing. Either way, i really don't think that moving a font would cause the phone to not boot up.
The phone booted up just fine an hour or so before this happened, so the font thing is the only thing I can come up with. I tried to use Wug's toolkit to push the font file to the N4 but the script gets stuck when trying to reboot.
Please help!! any suggestions?

do a factory reset via recovery
by copying system fonts which are not made for jb, your system could be damaged and thats the reason why you are in a bootloop..

What font did you push and how?

I'd really like to avoid doing a factory reset if possible, but that may be inevitable.
What I did was copy (move?) fonts from the system folder to a folder on the sd card so the fonts would be accessible to something I was making in UCCW.
When I boot into recovery all I see is the Android laying on its back with a red triangle and beneath that it says "No command."

And this is why you don't use a toolkit. It gives you ability to do things when you didn't know how to get there.
You should just factory reset and get your phone booting. I don't think you're in a position to be trying to save your data because you did things without know what was going to happen. Don't ever touch things in system unless you truly know what you're doing. Especially not without a nandroid backup.

I'm in over my head now, but I knew what I was doing at the time. I *think* I moved a ttf file instead of copying it. A brain fart led to all this. Live and learn and hopefully the community can help me out.
I do have a nandroid from a couple weeks ago that I'd be happy to flash but I'm not familiar with adb but I'm willing to give it a shot if anyone could help. Google hasn't brought me much luck.

Best thing I can say is to fastboot flash back to stock. Google on how to do it, there's a guide on XDA on how to restore factory stock images.
Start all over as if you just got your phone and don't do the same mistakes again. Spend the 25-30 minutes and read how to use fastboot, and don't do things without asking or thinking beforehand. If you don't know what you're going to be modifying or whatever, don't do it.
You don't flash a nandroid. You restore it via recovery in recovery mode.

So I booted into recovery, chose wipe data/factory reset.
After that runs, I reboot the phone and I'm still stuck on the X.
I've got the factory image tgz file but I don't know how to flash it

Use search + read stickies in the future.
Here is the thread you're looking for, http://forum.xda-developers.com/showthread.php?t=2010312
D. Type in the commands into the command prompt
1) Make sure your computer recognizes your device by typing: fastboot devices
2) Unlock your bootloader (if you have not already done so): fastboot oem unlock
3) You will see a prompt on your device. This will wipe your entire device (including the /sdcard folder). Accept. Note: you use the volume keys to change the option and the power button to accept. You cannot use the touch screen.
4) Reboot by typing: fastboot reboot-bootloader
5) Flash the bootloader: fastboot flash bootloader bootloader-mako-makoz10l.img (or whatever the name of the bootloader image that you downloaded).
6) Reboot: fastboot reboot-bootloader
7) Flash the radio: fastboot flash radio radio-mako-m9615a-cefwmazm-2.0.1700.33.img (or whatever the name is of the radio image that you downloaded).
8) Reboot: fastboot reboot-bootloader
9) Flash the system partition: fastboot flash system system.img
10) Optional (NOT optional for n00bs) -- Flash the data partition: fastboot flash userdata userdata.img Note: this command will wipe your device (including /sdcard), EVEN if your bootloader is already unlocked. See note 2 below.
11) Flash the kernel/ramdisk: fastboot flash boot boot.img
12) Optional (NOT optional for n00bs) -- Flash the recovery partition: fastboot flash recovery recovery.img
13) Erase the cache partition: fastboot erase cache
14) Reboot: fastboot reboot
15) Done! The first boot will likely take quite a bit longer than you are used to, as Android builds the Dalvik cache.

do flash the system and boot flash for sure.

thanks again. I must be awful at searching because I can never find what I'm looking for.
In the mean time, I figured out how to use the toolkit to flash the stock image and I'm back in business. i sincerely appreciate the help.

It's all good, I mainly use Google and type random tags on google like "how do i restore nexus 4 back to stock" or something between those lines and something would pop up. In general, Q&A there are stickied threads that has an index with a link to all the other pages that you're looking for.
It all comes with experience.
Errrrrrrr. Um.... you kinda killed me when you said toolkit. Don't use them it's what got you in this situation in the first place. Learn from your mistakes. The toolkit didn't necessarily bring you to this situation but you're not familiar with what the toolkit is actually doing and you're doing changes to the system because you aren't aware of what's going on in your surroundings.
http://forum.xda-developers.com/showthread.php?t=1469909 is a good thread on why you don't use toolkits. How do you think I know all this knowledge? Certainly not by using a toolkit. You have to know how to do these things, otherwise the next problem you'll have you'll ask questions some more. Please just take the time and read it and figure it out how to do it. It's not difficult by any means.
Good luck and glad I can help. I hope I could change your mind on the dangers of using toolkits and do it the traditional way with backgrounds of why you're doing this and that. If everyone used a toolkit then no one would be in Q&A forums could help others, like myself. If i used a toolkit, i wouldn't know how to fix your situation either. Thanks.

This is why we don't recommended using tool kits. You should try flashing the factory image using fastboot.

Same here, i tried re-flashing many times. Darn that nexus root toolkit

any suggetion or link which can help me to use fastboot use and install stock rom
thank alot for help

I am currently in the same position ! Used a toolkit too, always have.

This is why you never use a Toolkit, it's always been mentioned around in XDA that this has always been a developer website of learning and knowledge. You must always know what goes on behind than just blindly flashing things. It's a rule of thumb that you're more likely to brick your phone with a Toolkit than by yourself. Easiest step as follows.
1. Download factory image
2. Download ADB files
3. Make a folder and extract the adb files and factory image inside the same folder.
4. Plug the phone in bootloader mode or simply type adb reboot bootloader (Developer options must be enabled and USB Debugging) by exiting the folder, holding shift, right clicking the folder and pressing open command window and typing the command.
5. Every factory image comes with a flashall.bat, double click it and voila. Updates like it should. (User data will be wiped)
If you don't want your userdata to be wiped, simply open flashall.bat with notepad++, erase the '-w' in "fastboot -w update image" and save the file and launch it again.

Go to stock recovery and do factory data reset and reboot phone. First time boot takes very long time (around 10 to 15 minutes). After successfully boot into android L check for the storage space. If it says only 5 GB available instead of 12 GB (My nexus is 16GB) then Go to Settings > Backup & Reset and select Factory data reset.
I had experienced these issues when upgrading to Lollypop and solved them on my own.
Note: If you were not able to boot into stock recovery, try twrp recovery. you have to install it using fastboot
fastboot flash recovery <filename.img>

OK, I was able to get into recovery with this method, and wipe but I get can't mount cache errors during the wipe , waiting for the phone to reboot now, hopefully it will and get out of the bootloop. stupid thing is I'm not a noob, but stumped by this. Good excuse to upgrade to the N5 I guess

Wow, this method worked! Brilliant! Thanks, and dammit, it worked, 10 minutes after she agreed to me getting am upgrade !

For all of you whom are stuck in bootloop a fastboot oem lock comand when in fastboot will solve the problem.
So go into bootloader and run "fastboot oem lock" for some reason on some devices Android 5.0 won't boot with unlocked bootloader.

I am hitting this problem now, I got a OTA. After restarting its keep on looping waiting for more than 20mins still it's looping.

Tried going to boot-menu and did factory reset and it booted good after ~10 mins.

Power off, hold Vol Down + Power, when you get to the Android laying down, press volume up + pwr, then wipe the /cache from the menu (you do not need to do a full factory wipe, just wiping cache will do), and then reboot and wait. It will boot this time properly. @WugFresh is aware of the issue and said will put a fix in 1.9.9 for the N4

Thanks , I have tried clearing the cache and started waiting for an hour. Since it was still looping tried after factory reset/wiping user data. And then after 10min it came good.

(updated 29/11/2014)[not perfect but it is a SOLUTION]
The idea of this is to downgrade your nexus 4 without wiping your data, which means stuff you will need includes:
1. adb and fastboot on your computer (I am using mac but you can find it on windows as well. There are tones of website and forums telling you the latest method of getting it onto your computer)
2. factory image of nexus 4(I use 4.4.4, since that's what it was. I don't have the time and energy to try to do the same thing with lollipop. you can try can leave a comment).
update: do NOT try to flash 5.0 rom using this method. You will be stuck at boot loop again
3. usb cable
4. nexus 4 with unlocked bootloader(the process of unlocking bootloader will wipe your device)
5. computer
steps
1. unzip the factory image (something.tgz)
2. for me, after unzipping the .tgz, I still find another .zip inside. unzip that too.
3. hold vol+, vol-, and power button simultaneously to enter fastboot mode
4. open terminal(mac)(it would probably be cmd for windows)
5. connect your nexus 4(in fastboot)
6. to make sure it connect successfully, type "fastboot devices". if something like "005040c0d54bb291 fastboot" appears, you are good. Otherwise, try reconnect your device/boot to fastboot again/use another usb cable
7.now we need to tell the terminal to navigate to the location of the unzipped factory image. to do that, i suggest you put the unzipped folder to somewhere easy to find, like desktop. these are some commands to help you navigate:
"ls" allows you to look at whats inside the current directory of the terminal. For example, this is the output after typing "ls" for me:
some folder Photos
nexus4image.tgz how many folders do you have
5.zip occam-ktu84p
more folder occam-ktu84p.zip
after knowing where you are, use "cd" (below) to go to your folder
"cd" means change directory. For example. "cd Photos" will brings me to the "Photos" folder. And then if I type ls, I will see a whole bunch of photos in my photos. If you go to the wrong folder, type "cd ..", and it will bring you back to the previous folder.
8. flash bootloader.
enter the following command, BUT REMEMBER TO CHANGE THE NAME TO FIT YOURS(DIFFERENT VERSIONS HAVE SLIGHTLY DIFFERENT FILE NAME AT THE END(type ls first to help you type the correct name)
fastboot flash bootloader bootloader-mako-makoz30d.img
9. reboot bootloader. just copy and paste
fastboot reboot-bootloader
10. flash radio
enter the following command, BUT REMEMBER TO CHANGE THE NAME TO FIT YOURS(DIFFERENT VERSIONS HAVE SLIGHTLY DIFFERENT FILE NAME AT THE END(type ls first to help you type the correct name)
fastboot flash radio radio-mako-m9615a-cefwmazm-2.0.1701.03.img
11. reboot bootloader. just copy and paste
fastboot reboot-bootloader
12. flash system
system.img is located inside the zip, use ls to help you navigate. This steps takes the longest time, total time on this step is 87 seconds while the others are less then 1 second
fastboot flash system system.img
13. flash boot
boot.img is located inside the zip, use ls to help you navigate.
fastboot flash boot boot.img
14. flash recovery
fastboot.img is located inside the zip, use ls to help you navigate.
fastboot flash recovery recovery.img
15. format cache(not the memory, so everything should be fine)
fastboot format cache
16. reboot and wait
this will reboot your device. You probably have to wait for a while to initialise all the apps. after than you are good to go!
fastboot reboot

[Q] N4 stuck in boot loop after OTA update

Hello,
I saw that the OTA update to Lollipop was available on my phone today, so I went ahead and let it download. Upon completion of the download, it restarted and applied patches, then restarted again and has been stuck in boot loop for about an hour. After reading several other threads on how to try to reset the phone, I'm stuck. When I try power + volume up or down, the LED status indicator flashes red and I never get to any kind of other screen. Am I completely screwed? I previously had stock 4.4.2 with no modifications.

Finally was able to get to the bootloader menu. Apparently having the phone plugged into the charger was preventing me from getting there for some reason. I ended up having to wipe the phone to get it to boot

so you can get into clock recovery right? download nexus 4 toolkit..that might save your phone. I suggest you to unroot and flash everything to stock and then unlock again and start everything from scratch. good luck.

Similar issue on an OTA upgrade to an unrooted N4. It's stuck on the Lollipol boot screen with the rotating Circle thingies.
I can get to the Android System Recovery but there's no CWM or TWRP on my N4. I'm guessing a factory reset will fix it but is there a way to preserve my pics/files on the phone before doing so?

I guess TWRP Recovery has option to enable MTP and you can access the internal SD card by connecting mobile with computer using usb cable.

Flash TWRP Recovery using fastboot.
1. If you have otg y cable, connect it and use file manager to copy all the files.
2. OTG method is failed then select “Mount”, then select only “Data” and connect your Nexus 4 to your computer and Enable MTP in TWRP. now you can use adb pull and push commands.

I ended up going the factory reset route, which wasn't really a bad thing. My photos had been backed up in dropbox and the play store remembered all the apps and were able to reload them. The only things I really had to do was reload some music onto the phone and re-enter passwords for apps.

Same story here: sideloaded the OTA zip file, then had bootloop. Tried a few approaches, but none worked. In the end only wiping the data was the solution for me. Lost some userdata in a few important Apps...

I went through this yesterday. The only way to get it to boot is a Factory Reset from Recovery. It works like magic, but sucks you lose the data.

Got the OTA yesterday and also got a bootloop(stuck in boot screen animation). I couldnt afford losing my photos/videos as i had no backup , so i figured out a super easy to get it to boot without wiping data .
I was unrooted with stock recovery running stock 4.4.2, bootloader was unlocked. I flashed CWM recovery through fastboot and wiped chache+ Dalvik from there then simply rebooted the phone .
I had already tried wiping cache from the stock Android recovery,needless to say that didnt work for me.
If anyone else is having the same problem please try the method above and report back, cheers!

update: do NOT try to flash 5.0 rom using this method. You will be stuck at boot loop again
3. usb cable
4. nexus 4 with unlocked bootloader(the process of unlocking bootloader will wipe your device)
5. computer
steps
1. unzip the factory image (something.tgz)
2. for me, after unzipping the .tgz, I still find another .zip inside. unzip that too.
3. hold vol+, vol-, and power button simultaneously to enter fastboot mode
4. open terminal(mac)(it would probably be cmd for windows)
5. connect your nexus 4(in fastboot)
6. to make sure it connect successfully, type "fastboot devices". if something like "005040c0d54bb291 fastboot" appears, you are good. Otherwise, try reconnect your device/boot to fastboot again/use another usb cable
7.now we need to tell the terminal to navigate to the location of the unzipped factory image. to do that, i suggest you put the unzipped folder to somewhere easy to find, like desktop. these are some commands to help you navigate:
"ls" allows you to look at whats inside the current directory of the terminal. For example, this is the output after typing "ls" for me:
some folder Photos
nexus4image.tgz how many folders do you have
5.zip occam-ktu84p
more folder occam-ktu84p.zip
after knowing where you are, use "cd" (below) to go to your folder
"cd" means change directory. For example. "cd Photos" will brings me to the "Photos" folder. And then if I type ls, I will see a whole bunch of photos in my photos. If you go to the wrong folder, type "cd ..", and it will bring you back to the previous folder.
8. flash bootloader.
enter the following command, BUT REMEMBER TO CHANGE THE NAME TO FIT YOURS(DIFFERENT VERSIONS HAVE SLIGHTLY DIFFERENT FILE NAME AT THE END(type ls first to help you type the correct name)
fastboot flash bootloader bootloader-mako-makoz30d.img
9. reboot bootloader. just copy and paste
fastboot reboot-bootloader
10. flash radio
enter the following command, BUT REMEMBER TO CHANGE THE NAME TO FIT YOURS(DIFFERENT VERSIONS HAVE SLIGHTLY DIFFERENT FILE NAME AT THE END(type ls first to help you type the correct name)
fastboot flash radio radio-mako-m9615a-cefwmazm-2.0.1701.03.img
11. reboot bootloader. just copy and paste
fastboot reboot-bootloader
12. flash system
system.img is located inside the zip, use ls to help you navigate. This steps takes the longest time, total time on this step is 87 seconds while the others are less then 1 second
fastboot flash system system.img
13. flash boot
boot.img is located inside the zip, use ls to help you navigate.
fastboot flash boot boot.img
14. flash recovery
fastboot.img is located inside the zip, use ls to help you navigate.
fastboot flash recovery recovery.img
15. format cache(not the memory, so everything should be fine)
fastboot format cache
16. reboot and wait
this will reboot your device. You probably have to wait for a while to initialise all the apps. after than you are good to go!
fastboot reboot

Nexus Player Stuck In Bootloop

Hello,
I'm hoping to get some help with my Nexus Player that has been down since N Preview 1.
To preface this, yes I've been rooting and romming for years, I would not consider myself a "newb" in the slightest but no matter what I try, I can't get this working.
I enrolled in the dev program and did the OTA for Preview 1. It got pretty laggy so I went into settings and just had it reboot. Ever since I rebooted it, it's been stuck in a boot loop.
I tried the following things in this order using stock recovery only because for some reason I can't get it to flash a custom recovery (and yes, bootloader is unlocked):
1. Wipe cache via stock recovery
2. Factory reset
3. Flash factory marshmallow image via bootloader
4. Manually flash each partition separately
5. Wipe individual partitions and then reflash their respective images
6. Nexus Root Toolkit automated "Back to stock" feature
7. Flash Google's OTA Zip file
8. Ask for help on XDA.
Regardless of what I do or how I do it, I get errors in the command prompt when flashing via fastboot and when I try to do anything via stock recovery I get the error that you see in the video.
Any help would really be appreciated.

Here's a follow up video that shows the errors that I'm getting in detail.
Thanks again for your help.

Is there really anyone that can help me?

Which method did you use to try to flash a custom recovery? Nexus Root Toolkit fails for that function but I have had success when I use the fastboot flash recovery command manually. If you manage to get TWRP 3.0.2-0 to flash and reboot in to it, you can try flashing the latest system.img file from the recovery mode's GUI (after you've saved the file on to an external storage device).

Thanks. I'm know I tried to flash twrp manually at some point but I'll give it a shot. I may also try the "Boot into Custom Recovery" that a lot of the toolkits offer. Although, I'm pretty sure I've tried that in the past too.
I'll update with results.

Alright,
I tried flashing via fastboot and the command prompt completes and says it's finished but when I reboot to recovery I just get the standard Android recovery.
I tried locking the bootloader so I could then unlock it and force a factory reset but it wouldn't even allow me to lock it.
Again the command prompt made it seem like it worked just fine but it didn't actually do it.

Try the fastboot boot recovery (filename) command as an alternative. I suggest not using the current version of Nexus Root Toolkit for anything recovery-related when it comes to the Nexus Player. In other words, use the AndroidSDKSlim package and try things manually with the command prompt.

Okay. I'll give it a shot.

That command won't even work for me.

According to the attached picture, the actual command may be slightly different. Based on your most recent pictures, however, it seems that you may not be going through the manual process as I would expect. What I mean, for example, is:
1) Download AndroidSDKSlim.zip and extract it to your C: drive. Copy the twrp.img file to the platform-tools folder.
2) Use the search function of Windows 10 to load cmd.exe.
3) Navigate to the platform-tools directory by using the cd (directory path) command.
4) After you've navigated in to the platform-tools folder, try the recovery flash command I suggested earlier or the one shown in the attached screenshot.

I've uploaded what I did to YouTube.

Okay, I watched your video. The picture I attached in my previous post says to type in fastboot boot twrp.img whereas you still left in the word recovery before the file name.

Alright! I tried it and instead of rebooting into a recovery, it just reboots the bootloader.

Which recovery does it boot in to if you then use the bottom button to access recovery mode immediately after this step?

If that still doesn't let you in to the custom recovery, I'll quote WugFresh on something else you can try with his Nexus Root Toolkit (if you haven't already done so).
2. The toolkit can be used to flash these factory packages, but if you are experiencing "system.img" not found errors, due to a possible issue with google's package - simply enable FORCE FLASH MODE, which is in the toolkits main options menu (just make sure you have selected the correct device before flashing).
3. If you experienced any weirdness or you device is messed up, simply use "Flash Stock + Unroot' with "Softbrick mode" to restore your device back to stock (you can also use this to flash Lollipop directly - which, as I just mentioned - may be good to enable force flash mode first).

See next post.

I get the stock Android recovery if I reboot into recovery immediately after that step using the hardware button.
Also, I've tried the force flash through NRT, I've tried manually flashing each image via NRT (and via command prompt via fastboot). It seems to be able to write every single partition EXCEPT the system partition, and clearly it's having issues getting a recovery to stick too.

It's unfortunate that none of these troubleshooting ideas has worked for you. If a preview image of Android N caused this, I'm starting to think that a factory image of a stable Android N release may be necessary to fully flash the device.

I don't think that will work. Regardless of what image I'm flashing that shouldn't change the fact that I can't write to the system partition at all or that a recovery won't stick.

So I've waited all this time to flash the stable Nougat build on this Nexus Player and I'm still seeing all the same errors.
When I boot into stock recovery and "adb sideload" the update I get errors saying "unable to mount cache" and when I try to flash via fastboot I get errors saying it can't write the system partition.
I wish we could get some more attention to this thread, this is beginning to seem like it's impossible...
