Stuck at Google Screen... after doing a lot! - Nexus 7 (2013) Q&A

Hi guys,
So, I used to have some touchscreen issues, like, device going into standby, when waking up touchscreen wasn't working. After a forced shutdown usually solves it, sometimes i have to do it 2 or 3 times... but today.. after a forced shutdown, my tablet refused to boot.
So, following tutorials all around, I used fastboot to flash the original nexus image for 4.4.2, went fine, no errors (after a few retries), also flashed recovery (tried twrp and cwm), but the result is the same, google logo.
I tried flashing just fastboot flash system system.img, same for boot.img, still stuck at google logo. I got fastboot, but even selecting recovery, stays at google logo. I don't know what else to do. I know similar issues happen but usually they get sorted flashing either recovery or the image itself, but in this case, the tablet refuses to boot after a sucessfull image write.
Any tips? Thanks a lot guys, would mean a lot because I cant sent to warranty right away. Im not in my country (holidays) and I kinda need to use the tablet (ended up bringing it instead of my laptop, wasnt expecting this).
Any help is highly appreciated.
cheers!

Did you confirm that adb recognized your tablet while in fastboot? Open a command and type adb devices. What is the response? Do you have adb.exe and fastboot.exe downloaded so you can flash the zips?

adb nothing cause it stays in bootloader, its recognized in fastboot, thats how i was able to put the official google image.
I got it to boot now, randomly, out of nothing, did nothing at all and its okay.
I dont know why it happens but its the third time it does this after touchscreen stops working.
Anyway, until the next time.
I know touchscreen issues happen, but this random thing is driving me nuts.

[Q] [Cry] Galaxy Nexus bricked. (Dead fastboot, dead 3e recovery, only safemode

Searched all over and google yada yada yada. So i end up opening a thread here.
Hello guys/babes/kids/oldfags/ifags in disguise . I have a galaxy nexus here that will only boot into
-download mode,
- fastboot (not working at all, pc wont detect its fastboot and buttons all dead when in recovey/fastboot)
- safe mode - will boot into safe mode if i did combo buttons when attached to charger/pc
The story :
When i booted it from batt pull via only power button press, it will go into download mode straight and if i power off or factory reset in safe mode, it will reboot back into safe mode.
I cant flash anything since fastboot is broken. Ive tried Odin back to factory image of Galaxy Nexus GSM ICS and Jellybean but the prob isnt solved and fastboot is still broken. Tried repartition and bootloader update in ODIN yet still fail. And after every successful flash of repackaged stock, it will directly boot into safe mode (for both ICS and JB factory image). Why i didnt flash using fastboot? Fastboot is broken that is. Lets continue...
Other hardwares are still fine as in safe boot, ive tested all the buttons, display, calls, speaker etc. This is fastboot relate i believe as no matter what pc ive tried and all types of gnex drivers i tried. It wont even fart when connecting to pc(win7 x86). ADB works fine though when i booted into the safe mode. Im able to do adb stuffs but whenever i query it to reboot to fastboot or recovery, a dead end again. OMAPflash the tuna edition for omap4460? Tried yet still the same.
Additional facts : The phone was not unlocked and tempered by any way before the prob happened but now the bootloader is unlocked after i flashed the repackaged ODIN (chainfire posted it)
So XDA Gnex'ers, LET THE HUNT BEGIN!

First of all, bricked mean there is nothing beside a black screen. Nowaday device are hard to brick. second, One does not simply flash a gnex with odin. It's simply a big wtf that is shining through my head. 3rd, if fastboot is not working, it's because it need a special driver that i suppose you didnt install. If you can boot your phone in fastboot but can connect to it, it's because you have a broken USB port, which is not the case since you can access adb. 4th, i'm still trying to know how you achieved this. It look to me you were following some instruction and it either ended, tl;dr i will skip a few step, hope it will work which didnt or you missed electricity. Install Kies, get your phone in download and recover your phone from it. Never attempt again to play on custom rom. Man, how can someone derp a galaxy nexus, it is like the easiest device to work with.

Thx for the reply.
Some clarification here, im not the owner of this phone. Im using 9100 and im just helping a friend to recovery. Ive tried few pcs and it wont even fart when i plugged in during fastboot or recovery (i read someone that in recovery you can do some commands) but the pc(s) wont even detect a hardware being plugged in.
Plus, in fastboot, i cant press any of the hardware keys. No vol up or vol down and the power button dosent work in recovery. I only got to the 3e stock recovery via 'adb reboot recovery' during in fast mode where it booted into the relaxing chillin android with the triangle + red exclamation mark on its tummy. Pressed all buttons and it went to the 3e recovery.
At the 3e, only power button works. I cant toggle a bit using the vol keys. Note that the vol buttons work to boot the phone into fastboot and download mode and also during safe mode, all the keys works flawlessly.
So, i tried the odin method to recovery this living Gnex but with a faulty heart and kidney but it will still boot to safe mode regardless of ICS or Jellybean.
How did this happen?
I have no idea. The owner of the phone claimed that he has never rooted or tempered it in any way. Plus it was still on ICS when i first got the phone (all data was still intact but it was in safe mode at that time).
Regarding drivers, ive attempted many pcs with almost every drivers available. Shall i list em here:
- KIES
- Naked Nexus drivers
- PDA.net
- the 'official' gnex verizon driver set which is said working on GSM devices etc.
Tried those and adb+download mode works fine. Pcs detect em and tried to install the hardware n search for the drivers but not in fastboot. Its just dead.

Adb works fine so im able to pull anything when its booted. Im not sure if we can pull anything in download mode. Adb/fastboot didnt work in download mode. Am i correct? Mind to share some light here on this. And in fastboot, none. No vol keys to operate and the 4-5 pc ive tried wont even fart a sound or hint anything saying a hardware connected. Its like its a dead circuit plugged only in fastboot.
This is quite a super rare case here. Most of the dead gnex i found on the next and also in XDA has a working fastboot that only needs drivers to make it working but on this unit, even the vol keys is dead. Awkwarddddd

Great to know you are not the one who did that . So if i understand correctly, you say download mode work ? If yes, flash another stock rom from chainfire using odin. No one wan't to flash with odin, but if fastboot is not working, you shall at least try it. Also, when you are putting the phone in download mode and connecting it to kies, it should detect it has to be restored. i would say the main reason for it to not work is that android debugging is not ticked in developer options. But that would be strange that adb work on safe mode. There is probably a way to that with adb but you will have to google it. Tell your friend to follow instruction next time. And ffs, do not use odin ! (Little idea too, try to get in fastboot not connected on PC and wait a few minutes then see if you can move with the volume button, then try to connect it on pc)

only suggestion left is to just boot into fastboot, leave it alone for awhile (5-10 mins), then try and plug it in and mess with it.
Try doing the whole driver thing mentioned above but instead of flashing a Google image just do the boot loader portion, what settings are you using to flash in Odin?

adb does not work in download mode/bootloader. adb only works when adbd (adb service) is started, and that happens in android boot process. it means android debug bridge.

[Q] Anyone else experiencing this kind of bootloop?

Hey
I know this is a greatly discussed topic but I have been through countless threads and tried everything so please bear with me! Long story short, my phone is in a massive rut at the moment and nothing seems to get it out of bootloop (tried fastboot, odin etc; yes I'm not an expert at all but I'm not exactly a noob). Odin is/was my last hope and for some reason Windows XP seems to keep crashing it the minute I hit start. I read through numerous posts on the Galaxy Nexus forum and have also tried numerous other methods including trying to go back to stock via fastboot and toolkits, trying to flash .img files individually etc etc etc and I basically need all the help I can get if someone wouldn't mind? The phone does turn on to fastboot and is detected on toolkits and drivers are fine.
For those who need the info its a i9250 GSM maguro (UK version i.e. without google wallet) running JB 4.1.1. I did try to flash maguro ICS 4.0.4 and when I go into fastboot, the bootloader version has changed to PRIMELA03 whereas I'm sure JB isn't that but I may be wrong! The phone crashed 2 nights ago and ever since then it gets stuck in bootloop when switched on, the images are noisy and fuzzy as if the phone has some kind of virus and nothing flashes on it! Fastboot just crashes requiring a battery removal all the time. Odin crashes too so I cannot flash any other firmware. The phone is not rooted but the bootloader is unlocked and I have no SD card (obviously).
Sorry if I have posted in the wrong thread or done anything I shouldn't have -_- I just need help so someone PLEASE guide me in the right direction!
Thank you in advance!!
Update: I just tried to flash JB back over the bootloader version and it changed from PRIMELA03 to PRIMELC03 so the bootloader version does change however nothing else seems to flash!
Update 2: Think i finally managed to mess my phone up. Got the yellow exclamation mark triangle between a phone and pc -__- anyone have any insight on how to go around this? Everything I have read up has more or less got to do with all other variants of Gnex other than GSM!

Odin however doesn't go through the process of flashing it just says FAIL in red on top once I start the process because I cannot get the phone into download mode or fastboot.

Well I didn't use the conventional way; I had a the Wugs nexus toolkit (Yes I know xda doesn't take kindly to toolkits but I only use it to launch the ADB command prompt cos I don't really know how to use the SDK toolkit method) from which I launched the command prompt and used fastboot commands through that to try flash .img files to the phone. Unfortunately it all failed even when I could access fastboot. Now Odin doesn't let me flash anything either; It just says failed.
Sorry if this doesn't answer your question but that's how I went about doing the whole fastboot bit If you mean it crashes when you open cmd maybe try launch cmd through Wugs?

[Q] Fastboot has stopped working

Bit of an odd situation here, I want to upgrade the ROM on my arc, however fastboot devices is returning nothing.
I have used fastboot many times before, and it has been fine.
I can go into fastboot fine on the phone, and it shows up as S1 Boot Fastboot in remove devices, and as Android ADB device in device manager. I have tried this one two different computers with the same outcome.
Hope there isn't something broken in the phone!

[Q] [Help] Wiped the OS.. stuck at Google screen

So long story short, I think I fried my battery due to a faulty alarm clock app.. kept buzzing and heating up, I wiped it and accidentally formatted it completely (didn't know I could wipe the OS), but now it just freezes at the Google screen. I should mention I think the batterys bad, ordered another off Amazon and it wasn't the right one, so will only hold a charge with wall (or USB) power.
Can I force another OS onto this somehow? TYIA.
I assume you are unlocked. If so you have two options. Use adb in a custom recovery to push a ROM to your device and flash it. Or use fastboot to flash a factory image.

If you have a custom recovery boot into that and you can use adb, or you can boot into fastboot mode. But it's difficult to get this phone past the Google logo when there isn't a battery for it.

[Q] Is it possible to restore bricked device without usb debugging enabled?

I posted this Q in the sticky in general, I apologize for re-posting it but I don't know if that thread is followed much
A friend's flo suddenly bricked (error mounting cache) and he was on stock un-rooted
Since he doesn't mess with his device usb debug was not enabled at the time it bricked
So adb lists no devices, but fastboot works.
Even though fastboot works, when trying to unlock bootloader it hangs at "erasing userdata"
so there's no way in moving forward from here
I apologize if it's a common question, I did look around a little bit before asking but i come from a completely different device
Thank you for any help

Looks like its on stock recovery. Try erasing the cache through stock recovery 2-3 times. If it doesn't work you have to unlock the bootloader to flash the cache.img partition. It does take some time to wipe the userdata when unlocking it for the first time.
Code:
fastboot erase cache
Code:
fastboot flash cache cache.img
Thank you very much for your reply. It is stock recovery.
Clear cache from recovery was the first thing I tried, but it gives an error since it can't mount it
How long does it take the process to unlock bl the first time?
I looked at some yt videos and they talk about 10-15 seconds,
both times i tried I waited for over 15-20 minutes..

I don't remember it correctly but that much time should be sufficient. You can give one last try by waiting for 30 min to an hour.
IF you are not successful in unlocking the bootloader, then you may have to send it for warranty services. Maybe an issue with emmc...dunno really then.
Btw which usb port u r using? USB 3.0 has some issues with it. So try with 2.0
Although I've never used it I've heard a lot about a nexus toolkit on XDA that has a capability to flash system.img if the computer recognizes the tablet an I don't think you need an unlocked bootloader or USB debugging

Thank you, I know about usb port issues so I already tried all of them as well as different usb cables with no result
I found a few people which had the exact same problem as mine and they didn't really find a solution most sent it back for warranty
Some of these people talk about corrupt memory so there wouldn't be much to do in that case,,
Which toolkit is that?
I am on ubuntu and had a really hard time finding one that wasn't just for win..
I found one in nakasi thread which now also supports flo, but it always gets stuck at same point of bl unlock
Like I said, I've never used a nexus toolkit so i really have no idea what toolkit to use but there a lot of threads in the nexus 7 2013 q and a where it fixed peoples devices that wouldn't boot.

Ok, i'll try looking for it,
could someone though please tell me if the fastboot unlock process requires adb enabled or if it should work no matter what?
I'm starting to think that nand memory is corrupt therefore it's not accessible in any way and rma is only solution

Fastboot should work without USB debugging enabled.
I did a bit of research, its called the wugfresh nexus toolkit. I think that one is the best. Sadly you are on Ubuntu, you can install wine from the software center to run .exe files but I doubt that it would work through a Linux terminal because its designed for command prompt

React os will run .exe and its free but I doubt you want to lose your Ubuntu data.

Thank you guys for your help
I can get my hands on a win laptop it's not a problem, more the hassle of installing adb and the rest then cleaning up
But if we put all elements together so far i'm pretty certain it's hw failure
Do you think it could reasonably take more than 1hr to unlock bootloader if there was a lot of data on?
