[Q] N7 doesn't go past Google logo - Nexus 7 Q&A, Help & Troubleshooting

I was running an August MIUIAndroid ROM release, with no other modifications.
Downloaded the latest 12/10 release and placed it on my Internal SD. Rebooted to recovery, wiped cache, wiped dalvik cache and flashed the release.
Rebooted tablet, wherein it passed the Google logo and then just stayed blank.
Pressed volume up/down and power for a few seconds, went into fastboot. Tried to go into recovery by selecting that option in fastboot menu, tablet restarts and stays at the Google logo.
Went back into fastboot, connected the tablet to my PC with a view to using mskip's toolkit. PC doesn't recognise the tablet despite drivers being present, and the tablet becomes unresponsive in fastboot mode (can't move between menu options with volume buttons and even on disconnecting USB, have to long press power to restart).
Any help would be appreciated as I'm unsure whether ASUS will honour the warranty...

You said you can still go to bootloader, then try do manual boot(fastboot boot nameofcustomrecovery.img) and restore your backup(that is if you have any).

Easy
Connect it to the PC (better use the one you used in the past, with all the drivers... also use the cable that came with it)
turn it on spamming the vol until you get in the screen with start, shut down and recovery.
Go to recovery and boom, you are back to recovery
dont do nothing on the pc, just the fact that its connect will enable it:good:

Thank you for both of your replies.
This is what I did:
Connected my Galaxy Nexus to PC
Switched on USB Debugging, ADB drivers got auto-installed
Rebooted Galaxy Nexus into Bootloader, appropriate driver got installed
Switched on Nexus 7 in Bootloader mode, started praying
Swapped the Galaxy Nexus with the Nexus 7 - this time it didn't hang
Used mskip's toolkit to flash bootloader, stock recovery and stock ROM
Reason the tablet wasn't being recognised in Bootloader mode earlier was because while I had connected it to the PC many times, I'd never had USB debugging enabled (tablet was unlocked and rooted on my laptop) and had never been in Bootloader while tablet was connected to PC. So the PC didn't know what was connected to it, and presumably due to the issues with the tablet, the PC wasn't able to recognise it and download the drivers...
*huge sigh of relief* Thanks again guys!

[Q] Nexus 7 can't boot or restore

I made the dumb mistake today of flashing my Nexus 7 with the wrong gapps and as a result setup would continuously crash.
I first tried to reboot into recovery by entering fastboot mode (power + volume buttons) but all i got was the google logo for all eternity
next I tried reverting to stock with the nexus 7 rootkit but it always failed on the fastboot check saying my device could not be detected.
Assuming my drivers were not working correctly I manually installed the google usb drivers and at this point if I look in the device manager I see Android device > Android Bootloader Interface but if I run the adb devices command I get nothing.
I feel like I'm at the end of my rope here so I could use any suggestions.
p.s. usb debugging is not enabled because I had just done a factory reset and I can't enable it because I can't really access anthing after booting up.
solved
Ok so after installing the google driver I decided to give the root tool and leaving my nexus 7 plugged in for a while I noticed that the fastboot screen was no longer frozen and decided to try the rootkit again and this time it worked like a charm so problem solved!!!
I guess I couldn't detect it with adb because usb debugging wasn't enabled but the rootkit was still able to restore it using the fastboot method.

[Q] Nexus 4 recognised as qualcomm device 'bricked'

Hi all, I posted several questions in the Nexus 4 Q&A thread but the situation has gone from bad to worse so decided it would be easier to just create my own thread...
This started off with being unable to boot the phone into the OS, Fastboot and Recovery mode were both accessible although wiping the cache failed to do anything it just returned unable to mount cache errors.
I then attempted to unlock the bootloader so I could load a custom recovery and try repairing, however upon selecting "yes" to unlock the phone the screen flashed the fastboot screen up then went blank and has stayed blank since, all I get now is a qualcomm usb device detected when I plug it in.
Installed Qualcomm drivers and the phone is recognised as being in download mode in QPST but from what i've read on this site so far it seems no one has been able to unbrick a Nexus 4 using QPST?
I read the unbrick guide using LGNPST, the software recognises a device being connected but it keeps prompting that the phone is off or unplugged even though windows is still detecting it as plugged in (qualcomm device detected, no noise for device unplugged etc).
Finally if I hold down vol-/+&power when connecting the USB lead the red LED comes on (solid) for about 3 seconds.
Do I have any option other than RMA?

[Q] Soft-Bricked Refurbished Stock Nexus 7

I recently bought a refurbished 2012 Nexus 7 on 4.2. The only things that I have done on the phone are entering my Google account details and downloading a single app (papyrus). I then clicked to install the automatically downloaded software update (it downloaded 4.3), and after restarting the tablet was stuck on the Nexus X boot animation forever. Factory reset/cache wipes do not help.
I found drivers for the phone to be recognized while showing the X, and I found drivers for the phone to be recognized after selecting the a "apply update from ADB" option from stock recovery. However Windows does not recognize the phone at all in recovery mode before selecting that option. Nothing changes in the device manager when plugged/unplugged. Windows doesn't attempt to install anything. It's as if I unplugged the cord once it enters recovery from the bootloader. I assume USB debugging is off, because it would be at the default setting. I tried using the Flash Stock + Unroot option in the Nexus Root Toolkit with the Soft-Bricked/Bootloop setting in, but that fails in both normal recovery (with the device unnoticed) and sideload mode. I'm guessing that debugging needs to be on for this?
Does anyone have any suggestions for other things to try? I have no way of knowing what the original owner may or may not have done, and this was the first time that I restarted the device, so I have no way to know if the problem was caused by the OTA or not.
EDIT: It looks like I made the situation worse. I attempted running the Flash Stock + Unroot option from the bootloader. I am not sure what happened, but now the device starts at the Google page with green start in an arrow. I have the bootloader options, and start and recovery options give me a "booting failed" message in the top left and just stay on the google page. Restarting the bootloader gives me the normal bootloader android image and the options have the same effects.
For anyone who runs into this problem, I seem to have at least temporarily solved it.
I followed the advice here to manually flash the factory image. I am now back to where I was when I bought the phone, and I will immediately enable debugging and test it's ability to restart, connect in recovery mode, etc now.
EDIT: It can restart normally (with the unlocked logo), but it is still completely unrecognized in recovery unless I choose the sideload option like before. Should I return the tablet?

still have a problem?
Wrong drivers, try other USB ports. Had that happen with another tablet. Only recognized in adb side load with galaxy nexus driver loading, possibly from universal adb drivers... Switched to a port on the other side and correct drivers finally worked.

As far as I know, no. I was never able to get the device is to be detected by my computer while in stock recovery mode, however it was detected after I flashed ClockworkMod Recovery. So I still have no idea what was causing that problem, but it is no longer relevant.

[Q] Galaxy S-5360 No Download Mode, but Recovery Mode Works

I am new to posting, but I have followed XDA for a long time and used it to install custom ROM's on other phones. However, I now have a problem with my wife's Samsung Galaxy GT-S5360L. I have searched for hours, but can not find a solution.
The phone is stuck in a boot loop. I can enter stock recovery mode. When I try to perform a factory reset, I get the following message:
E:format folume: rfs format failed on /dev/stl11
formatting /cache
Data wipe complete
After wiping the cache partition, the phone continues to be stuck in the same boot loop after reboot (Samsung logo appears on screen, followed by animation, back to Samsung logo).
The phone will not enter into download mode. When I press power+volume down+home, I see a white screen, followed by a black sreen, followed by another white screen. the suggested method of removing the battery, SIM, and SD card, and plugging into the computer while holding both volume buttons does not work. Odin will not recognize that the phone is connected.
I tried to connect the phone to two different computers. One runs Linux mint with Windows XP on a VM. This computer has always worked for flashing ROM's to other phones. Odin would not recognize the phone, and I received messages that the device was not properly installed.
I then tried to connect the phone to another computer with Windows Vista. This PC has Kies installed and Samsung drivers. Kies would not connect to the phone, and I also received messages that the device was not properly installed. Odin would not recognize the phone. I should note that the phone has interfaced with this computer sucessfully before.
This phone has never had a custom recovery or ROMs installed. It only has the original stock ROM. Is the phone's hardware defective, or can it somehow be fixed? Please post any links to threads that I may have missed. Thanks.
Download mode is only effected by a change in bootloader normally by Flashing incompatible firmware or a hardware fault
For flashing via odin kies is not required - its useless as it's not compaitable with the galaxy y for this purpose
You just need the Samsung USB drivers available from my firmware thread (links in signature)
It maybe possible to still flash the device
Once USB drivers installed
Enter download mode
Connect USB to pc
When the white screen appears push Vol up
Wait a few seconds
Open odin
Put the 3 firmware files in their places & flash
If it doesn't flash you will either need to flash a new bootloader via a jtag (repair shop) Or replace the motherboard - either way unless you can get it done very cheap it's more economical to buy a new phone
Thank you marcussmith2626 for your sound advice. The phone is working again. I will share the problems I solved in order to flash the stock ROM. Hopefully this will help anyone else that may have a similar problem.
The Samsung USB drivers had been previously installed on my PC running windows vista. I installed the drivers so that I did not have to use the bloated Kies software. However, when I tried to connect the corrupted phone to the PC via USB, it was not recognized, even though the correct drivers were installed. Below is the procedure I had to follow in order to connect the phone:
1. I connected the phone to the computer via USB. The phone had the battery installed and was powered off. After connecting to the computer, the phone started charging (battery icon on screen). Connecting in download mode at this point did not work. The phone must be powered off.
2. When the "found new hardware" notification box appeared, I had to make a note of each device that had been discovered.
3. I then had to open Device Manager from the control panel and find each device (the name in Device Manager matched the name in the new hardware notification).
4. I right clicked on each unknown device and selected "update driver software"
5. In the next menu, I selected "Browse my computer for driver software"
6. In the following menu, I selected "Let me pick from a list of drivers on my computer"
7. This brought up a list currently installed drivers. I selected the Samsung phone driver.
8. The driver then installed for the selected device..
9. Steps 2 through 9 were repeated for each new device discovered by Windows (each device listed in the "found new hardware" dialog).
10. I started the phone in boot mode (power+home+volume down, phone still connected to PC). I saw only a white screen. However, when I pressed the volume up button, the phone connected to the PC. Odin recoginized the phone and the stock ROM was flashed.
So, even if you only see a white screen, download mode can still be active. In my case, the drivers on the PC were not working correctly, probably due to the corruption of the original stock ROM. The drivers can only be added on my PC using the above method. The option to choose from a list of currently installed drivers was not available from the found new hardware wizzard.
Also, I will also say for reference that in the USA, the stock ROM from Brazil is the one that should be used so that the phone broadcasts on the proper GSM frequencies.

Note 4 android control droid screen issues.

Hi all,
I am having a slight dilemma with my UK Note 4 N910F. I broke my screen while trying to replace my rear camera (long story). Now I have a phone that still works apart from the screen is dead.
My next problem is my phone is stock, USB debugging not enabled and has a password/fingerprint lock on it. The fingerprint lock won’t work due it being the first time the phone gets turned on after a restart it doesn’t work. I have looked into “recovering the data from it” for quite a few days now, and am at a dead end.
I first downloaded Android Control & Droid Screen and finally got them to work after having a windows 10/java nightmare.*
Downloaded and installed SDK platform tools and ADB drivers and to no avail it still would recognise my phone in “adb devices” so I thought this must be because USB debugging isn’t enabled.
I then installed Samsung Odin 3 and flashed Clockworkmod recovery which I believe has worked fine.
Still “ADB devices” nothing listed.
I then downloaded Dr.Fone (trial version) and started the data recovery and pulled my phone half way through. Which leaves it in recovery mode. Closed Dr.Fone reconnect my phone and I can get adb devices to show a “serial number recovery” listed.Droid screen detects my device but says its offline, and I can power on/off reboot etc my phone through android control.
If I reboot my phone then I lose recovery and droid screen/adb/android control wont work anymore.
Is this because it is resetting USB debugging enabled option?
Is there anyway when im in recovery mode I can enable USB debugging and keeping that setting if my phone is reset?
Any advice would be great.
Regards Jim
