[Q] Nexus 7 wont boot

I was playing a game on my nexus 7, it froze then when rebooted it it just got stuck on google screen. Read a bunch of stuff, went into recovery and tried to recover, it would say erasing but never go any further, just sits there. got toolkit tried to restore factory with that, now when it boots I still just get google screen but I get the menu in corner for start/boot/recover/power off. still never boots, when I try to run recovery now it doesnt even go to erasing. Ive read everything I can find to restore it, got 2 toolkits, unfortunatly everything tells me to put it in debug mode, which is funny cause if I could boot up and go into settings to turn on bebug mode then I wouldnt be having these problems... Can someone please help, Im good with computers but dont know much of tablets. I did no messing with tablet besides downloading updates when they came out.

unlock bootloader

My guess is no, I never messed with any of my system stuff. Everything was factory except for the updates it had me do as they came out.

How long you let it sit in recovery erasing before you rebooted it? Is there an option in boot loader or recovery for a factory reset? Beings you're not rooted I doubt those one click tool kits will work for you.

It sat in erasing for 1 hour and didnt do anything. I was doing factory reset in recovery.

As long as the boot loader starts you can recover your Nexus. Check this guide: http://forum.xda-developers.com/showthread.php?t=1907796

If he can't unlock the bootloader then there's not a whole lot he can do. Run "fastboot getvar all" while in bootloader and tell us what it says please. If adb is seeing your phone in recovery, then run an adb shell and do "ls -l /dev/block/platform/sdhci-tegra.3/by-name/" please.

Sorry I can't help further but I just got this and don't know much. I am glad others came in to give you more help.

Damn... I didn't see he can't unlock the bootloader. This is going to be difficult.

Just sayin, I think you guys need to pull the back cover and disconnect the battery for at least one hour.
I am really new at this but it helped me save mine twice. I think?
After you plug the battery back in try fast boot.

But this will void my warranty right ?

They have no way in knowing you pulled your back cover off. Just be careful so not to leave pry marks. Only way they will know is if you tell them you did it.

[Q] LG G2 is bricked...

Hey guys and gals...It really looks like my phone is screwed...I recently updated to lollipop which is awesome and i thank you guys or gals for all the work you've put in. Last night I decided to go into updates and without knowing what it was going to cause, I clicked on one of the updates and went into that CYANOGENMOD screen. I could turn the phone off, but that's about it. My question would be if it is possible to get a fix on this or not? Thanks for any comments.

We need more info. What device version are you on? Does your windows pc recognise the device? Have you tried to restore the device with lg's flashing tool? Does the phone still boot to the cyanogenmod boot animation or just dead in the water?

(chihuas33) Thanks for your reply...The device I am using is for AT&T which is the D800. When I plug in my device to my laptop it does recognize it but that's as far as it will go. I have not tried to restore with LS's flashing tool because I had no idea about it but I'll check it out. My phone does boot to cyanogenmod and does not go any further. Any feed back would be awesome.

Sounds like your device is in a boot loop pal. Boot into recovery of possible and wipe cache+dalvik cache and see if it helps

Bootloader Unlock/Root - What I've Got So Far <Updated 5/22>

11/21: Note from those working on root: "Do not update past ZV6 at this time, as we're working on a root method for ZV5 and ZV6"
[OLDER]
5/22: Sorry for not keeping this updated guys.
Promising developments on the Snapdragon 820-based S7/Edge HERE
G5 Root bounty thread HERE
All in all, it looks like root's on its way! Please keep posing any root/unlock related info you see and I'll keep this updated.
UPDATE: It appears that they've achieved root on the T-Mobile variant and a tool should be forthcoming.
No word yet on whether or not this applies to us, but here's hoping!
Video here: https://www.youtube.com/watch?v=Zlieyd9CP7Q
EDIT: It's confirmed, the bootloader on all of the snapdragon G5's is locked down tight.
It looks like there's not much we can do until someone figures out a way to crack the bootloader.
Sooo, it appears we've got the "Enable OEM unlock" option in our Developer Settings, but so far I've not been able to get the phone into Fastboot mode to actually perform the unlock.
I do have the following observations if they'll help anyone:
With the phone powered off, the following options are available:
Power+Volume Down - Boot to Recovery
Power+Volume Up+Volume Down - Displays Phone Identity (IMEI, etc.)
Volume Up+Connect to PC - Download Mode
Attempting to reboot to bootloader via adb command or from the stock recovery results in a normal system boot.
Hope somebody can use this.

yeah, I saw that. Hopefully that means root is possible. Great phone but I'd like it a whole lot more if I could get at the hosts file for ad blocking and a couple of other tweaks I'm used to.

Does the same method that the people over on the tmobil version work. They already have twrp posted.

I looked at that thread again today. Looks like it was an April Fools...
The dev has TWRP builds that SHOULD work, but no way to flash them, as all variants appear locked.

I edited the title to show "Not Working" for that version. I left the thread open however because they are discussing attempts to get through it.

Looks like it will be the g4 all over again. Its a shame.

How long it took to get root on g4?

attempted what? its a work in progress. decryption is still not working, and the method hasn't been released or turned into an easy repeatable process yet. It's just a proof of concept and proof that it CAN be done right now.

Just a side note, tried adb reboot recovery and it wiped my phone, don't do that lol.

When you say it wiped your phone, did it completely wipe the system partition? or did it do a factory reset type wipe?
My phone got all weird during activation and it thinks it activated even though I get no service, when I did a factory reset from inside the OS, when the phone turned on, it assumed it was already configured on the network and actually asked me to manually put in date and time and didn't ask to sign into a google account or connect to wifi, I'm trying to do a full factory reset to try and get it to go through the activation process again.

In the dialer do ##RTN# then reset and enter your MSL. If you don't have it you can use the guide to get it.

adb reboot recovery seemed to do a full reset, with user data partition completely erased since it was encrypted. Also it had to reactivate itself.

I now have the ls992 and the vs987. If I can contribute in any way, please let me know.

NEXUS 6P Bootloader stuck

Hi everyone,
I rooted my nexus 6p using Nexus Root Toolkit, the root was succesfull , then I went to recovery mode to flash the images for the new google assistant (im not sure if this is what cause it) , the device will turn on with this message "Your device software can't be checked for corruption. Please lock the bootloader." , then after 3/5 seconds it goes to a Google Logo wth a small opened padlock where th home button is. but it never fully boots, i can access the bootloader and get into the recovery mode, but thats all, how do i fix this?
Many thanks
Jacob

I'd suggest flashing the factory image via fastboot and doing a complete factory reset as per Heisenberg's guide.

Yep, it bootlooped for me too. I restored from a backup but without a backup, clean wipe will square you away.

i know this is silly but I'm sorta new to all this, how would i do that haha

Look for a flashing guide in Nexus 6p General forum. A complete guide to updating your phone to stock or flashing roms for all scenarios.

I tried relocking the bootloader and messed up

[SOLVED]
Hello, so i followed the guide on here to go back to the stock rom from LOS(Lineage OS). I had done that right. Then i tried relocking the bootloader. I did that successfully. Now, i have 2 problems i have run into.
1) there is no recovery mode
i tried booting into recovery and all it does is flash the ZTE logo for a second than turn off. This keeps happening. I am not sure how to flash the recovery image since the bootloader is locked and i have no recovery mode.
2) when i boot my device, it asks for a password (a 3x3 grid).
I tried typing in the password i used for TWRP and it didn't work. I tried a bunch of old passwords but so far nothing has worked. I would like to know how to get the password and turn this off. I found this very annoying on LOS.
Please help me as i am not sure what to do!!
edit: i cannot seem to get the device to conect to the computer using adb or fastboot.
if you can can we excahnge phone numbers to fix this faster?
