Stuck in the coloured circles...

Hi Everybody,

I haven't been here at xda developers for quite a long time as I stopped rooting and flashing my android devices some time ago... :)

Though I still like the platform and have a totally factory status Nexus 7 which stuck in the coloured circles screen when booting. I did not modify anything, just always installed the official updates.

I did not use it for a few days, and I think the battery was completely drained. I've put it on charger last evening, and bring with me today. When I took out from my bag to switch on in the afternoon, it was hot, and couldn't switch it on at all. Now I can reach the coloured circles, but nothing else. They keep on dancing, the device is getting hot, and nothing happens. :(

I've did some research and could get into fast boot mode, but I have no utility installed on my computer (currently a mac), so can't do anything in recovery mode, I tried power off and then start normally, also start from fast boot - but always the same.

Is there a way to solve this without installing anything on my computer and digging into the tablet's system settings/recovery/etc?

I'm sorry, if this question was already asked and answered, I couldn't find it. I know how annoying is to answer the same question several times, so I really appreciate any help. Even a link to the place where I can find the solution...

Thanks in advance,

J.

Have you tried to enter recovery and wipe cache and dalvik cache? That would be my only suggestion without tools installed on your computer.
[Nexus 7 Q&A, Help & Troubleshooting] jnemeth:
Thanks for the answer.

Actually I tried to enter to recovery and system response was a "no command" message on the top of the green android robot... Then after a few seconds it powered off automatically. How to wipe those caches in recovery?

Edit

Now I formatted the cache partition - nothing happened

After this I made a factory reset - that helped, with erasing all data, of course. But at least I could switch this thin on again.

hey,

i couldn't find anything related in the forum which is why i'm asking:

i'm currently on liquidsmooth with android 4.4.4 and f2fs. i thought about going back to 4.1 because back in the day the n7 was (at least in my memory) blazing fast. i'm using the n7 just for media consumption and surving the web. nothing i really need kitkat for and jb can't provide.

i found a couple of guides how to go back to 4.1 (basically it's just flashing 4.1, right?). but i'm not sure whether i need to go back to ext4? if so, how can i do that? i didn't find any guide on that.

thanks!

Stuck in bootloop

Hi,

I was using Slimkat 4.2 with TWRP recovery. Wanted to update to the latest stable build. Did so. Now I'm stuck in a bootloop.

1) I restarted in bootloader, went to advanced wipe and wiped system, dalivik cache and cache.

2) Then I flashed the file (Slim-grouper-4.4.4.build.7.0-OFFICIAL). Sha1 check out. My device is a nexus 7 2012 (non 3g).

3) on top of that, I flashed the latest gapps normal.

Bootlooped.

1) I'm able to enter into bootloader.

2) I do not have a backup of my previous instal :(

3) I am unable to mount usb through the twrp mount interface.

Could somebody help me here? I seem to be making a lot of mistakes with this after successfully flashing my phones for years (just recently I got a "enter password to decrypt device" on the same nexus 7 that I got through by formating through twrp.

Should I try wiping and flashing the rom again, without the gapps? (By wiping system, dalivik cach and cache)?

Are there other methods I could use?

Help would be greatly appreciated!

Please note that I can easily get into fastboot mode. When I'm at fastbook, should I just try to return to stock? I'm not exactly sure how that would work given that I have a custom recovery and rom installed.

Should I try to use sideload adb to instal the rom/original rom for the device again?

Rooting/Downgrading over wifi?

I want to know if it's possible as I don't have a usb port (it popped out it's socket) I charged it by modifying the pogo pins.

I have a stock nexus 7 2012 16gb running KitKat 4.4.4 (Bought used it's why it did not have a usb socket and was just dead) I've tried Towelroot, rootmaster, and farmaroot all failed -_- so I need some help downgrading or somehow root my device. Thanks.
[Nexus 7 Q&A, Help & Troubleshooting] GedBlake:
Hi, Crazy Potato...

Without a working USB port on your Nexus 7, you're pretty much out of luck rooting or flashing anything... manually upgrading or manually downgrading Android.

The methods you've referenced above (towelroot, ROOTMaster, and Framaroot), are kernel exploits which 'exploit' vulnerabilities in the kernel, in order to acquire root.

The problem is, Google have been chasing down and successfully closing these vulnerabilities with each successive release of Android (implementation of the SELinux hardened kernel, for example), because they are potential security risks. This policy accords with other security orientated measures Google have implemented recently, such as Android 4.4 KitKat restricting write access to external SD cards on devices which support them.

*****

So, with exploits seemingly no longer an option, the only way of rooting or flashing (downgrading?) anythng on the Nexus 7 is via the old fashioned way... that is to say with the fastboot tool... and unfortunately that does require a PC-to-Nexus 7 cabled connection... and obviously, a working USB port on the tablet itself:(.

So if you can't get your USB port repaired, you're 'stuck' on whatever version of Android is currently installed on your Nexus 7, and the only way that will change is via an official OTA update from Google.

The good news is that might be happening within the next few weeks, with Android 5.0 Lollipop waiting in the wings... and which the old, original, first generation 2012 Nexus 7 apparently WILL be getting:)... if these articles are to be believed...

http://arstechnica.com/gadgets/2014...ng-nexus-4-and-2012-nexus-7-will-get-lollipop

http://bgr.com/2014/10/15/android-5-0-lollipop-update-for-nexus-4-5-7-10

http://www.androidpolice.com/2014/1...ive-the-holy-blessing-of-android-5-0-official

Of course, notwithstanding damaged USB ports, Lollipop will bring it's own fair share of difficulties with regard to gaining root, and apps which depend on root... and all compounded and complicated by Android 5.0 default device encryption and the new Android Run Time (ART in place of Dalvik)...

http://www.androidpolice.com/2014/1...iew-modified-kernels-may-become-a-requirement

*****

I wish I could help you, [MENTION=6102879]Crazy Potato[/MENTION], but a damaged USB port severely restricts what you can do with your Nexus 7. You're essentially beholden to what Google 'pushes' to your device via OTA's and you won't be able to root it:(:(:(.

Ged.

Nexus 7 3G (2012) with "nakasi" firmware?

Hi!

Does the "Nexus 7 3G" ("tilapia") work with the "nakasi" ("WiFI only") Firmware?

I would guess: yes, since the hardware appears pretty similar, but of course all 3G functions would be missing.

Which is exactly what I'm seeing on my Nexus 7 3G.

This is a refurbished device I got from Google in exchange for my defective unit - i suppose they flashed the wrong firmware during the refurbish?!?

Does anybody here have another explanation for this behaviour?

The Google support doesn't seem to believe me (or they don't understand the problem) and keep telling me to reset the device, insert the SIM and so on...

I think flashing the "nakasig" firmware should fix the problem, right?

I want to try f2fs filesystem and i want to test it using stock android 5.0.

How to flash ROM w/out ADB

Hey Guys,

So I have a Nexus 7 2012 wifi edition that someone gave to me to fix.

I have had experience with installing things like CWM then installing Cyanogen on top of it. (galaxy S3, nook, etc.)

However I am encountering a new issue here.

They seem to have removed their stock ROM, leaving me with no options to enable USB debugging.

So when I use ADB to show connected devices, the list is blank.

I normally just pull the SD card and copy/paste the ROM in it's file path, but this has no removable SD Card.

Current status of device:

CWM recovery has been installed and the device boots into recovery with no issues//cannot boot into ROM, possible no ROM data exists on the device. Fastboot is able to see device.

Question:

What would be the best way to flash a ROM on over to the Nexus without the use of ADB/is there a way to get ADB to recognize the device to flash the ROM on over?

Any help provided would be appreciated at this point, thank you for your time.

Edit: Solved
