[Nexus 7 Q&A, Help & Troubleshooting] nikola1970:
Updated my Nexus 7 2012 32 GB to 4.3 (unlocked bootloader and rooted) and i have to admit that 4.2.2 was working smoother in some cases then the 4.3 which i currently run.

Updated to 4.3 not via OTA, but flashed the factory image. I experience some mini lags on the soft keys, and as well while i press a button next to home one (it's the 3rd button, right one, i dont know how it is called :o ) , also when i exiting recent applications (moving them them to right) and when there are many of them i notice some black artifact on the screen when the last one at the top of the screen appears, and that was not a case with 4.2.2. (can u guyscheck if this is a case with your 4.3 N7 as well?)

Tried a factory reset few times, didnt help. Checked a freind's Nexus 7 4.3 and it's the same thing with his.

Beside this, it looks like the same as 4.2.2, didnt notice any prerformance boosts, but my 4.2.2 was working prefectly so that might be a reason, i never had any lags on my Nexus 7 before.

No such issues here. Maybe redo the Flash, by doing a clean reflash.

If this is the NeXus 7 2013 you'd be farther ahead asking in that Forum. It's a very different beast than the original N7.
[Nexus 7 Q&A, Help & Troubleshooting] nikola1970:
marathone can u recommand me a way to do a reflash? Coz i flashed mine with Nexus 7 Toolkit, but now i can't do it coz i have to choose my current operating system, and it's not updated for 4.3. I could choose 4.2.2 when for my current version when i was flashing to 4.3, but now i can't coz there is no 4.3 option for a cureent version which u must to choose.

Use ADB, or if on Linux, http://xdaforums.com/showthread.php?t=1848036

A prime reason tool kits allow people to do things they don't understand, causing problems when something goes wrong. You'd be further ahead learning ADB.

I have a question about kernel. If I have 4.2.2 I understand that I cannot upgrade the kernel to Francos r75, because it s for 4.3, but can i just something like r65?

Also, does CyanogenMod improve battery or performance (or any other ROM for that matter) , or that's just the kernel?
[Nexus 7 Q&A, Help & Troubleshooting] Red Devil:
you can flash R-65 . The battery life you get on your device depends on a large variety of factors. A combination of a ROM + Kernel and your usage of the device decides how much battery life you get . Yes, some kernels have wakelocks that keep the system processes alive and drain battery .. So you can use any 3rd party app to detect where exactly the drain might be occurring. Some Roms have some features that once enabled may drain a lot of battery. Many of the times , its the usage by the user that decides the battery life. Try to always turn off GPS , WiFi , Bluetooth and NFC whenever not in uuse. You can use trickster mod settings to under clock a kernel ( which supports under clocking ) and use governors like powersaver etc to increase battery life. Hope that answers your question.
[Nexus 7 Q&A, Help & Troubleshooting] icamaster:
Thank you for your answer. I am about to flash 4.2.2, and I wasn't sure about it.

Would you recommend to just go with 4.3? I saw a video where there are no major differences between the two, but some claim that the old N7 (which I have) is slower on 4.3. Is this true?

LE. I updated 4.3 and unlocked + root. So far it s good.
[Nexus 7 Q&A, Help & Troubleshooting] Red Devil:
I will not comment on which is better or which is worse. Try both of them and test it for yourself. For me, personally.. The difference between 4.3 and 4.2.2 is pretty significant and I dont see any compromise on features , stability and usability by Google in the update. Besides , an update is an update.
[Nexus 7 Q&A, Help & Troubleshooting] icamaster:
I flashed 4.3 and i'm happy with it.

Hello again. I come with another question.

Let's say I want to try CyanogenMod 10.2 . I backup my stock with TWRP and then flash the CM. As I understand i will not loose anything, because you don t have to wipe data when you put custom ROM over stock. But what if I want to put stock again, will I loose anything except apps installed after i flashed CM?

In other words, can i just test CM and then revert to stock without loosing data and without any backup like Titanium backup?
[Nexus 7 Q&A, Help & Troubleshooting] Red Devil:
No you've got that wrong. When you are switching over from stock to any custom ROM it is always better to do a full clean wipe I.e. system , data and cache and then flash the ROM. That is the only way you can test a ROM. Always backup apps and whatever data you need. Taking a backup from the recovery is Called as a nandroid backup . on restoring the nandroid backup your tablet will return to the exact same state as it was before taking the backup .. with all apps and all.
[Nexus 7 Q&A, Help & Troubleshooting] icamaster:
Thank you for your answer. Another question and that's all. Can I move my nandroid backup from my tablet to my PC? Just to save space and just move it on my phone when i need it.

NVM

I will just use Titanium Backup. I had it installed on my phone and i just saw it and remembered about it.
[Nexus 7 Q&A, Help & Troubleshooting] Red Devil:
Yes you can .. Why not.. Its best to keep a copy of your backup on PC .. Just in case something goes wrong. However it does not backup the sdcard. So be ware.. Cheers

problem with my nexus 7

I'm using nexus 7 3g version. Its unlocked and rooted with nexus root toolkit. I never had any problem with it before. So i had the pop up for updating to 4.3 and i selected it. So it was downloading and when it was complete, it booted to recovery. I was sleepy, so i was not really aware of what was happening. When the process was over, i just selected reboot and it got stuck at the X logo. When i turned it off, it wont boot normally unless I hold the on button for >30secs and it still is stuck at the X logo.

I used the toolkit and tried to flash to stock but failed. Next i tried wiping the nexus so i can put in a stock rom manually or maybe even a custom rom. Even then, then file wont install completely and the process always gets timed out after a while.. I cant even push files in. Now i have no OS and cant enter recovery unless i use the toolkit and use the custom recovery.

Can anyone help me out here? Thanks a lot for your time.

Greetings!

I have three problems (questions) that really needs to be solved or at least explained to me (in a newbie-friendly way). Please keep in mind that these are all related to my Nexus 7 32gb wifi, rooted with wugfresh' toolkit, stock ROM 4.3.

1. Is there a way, like perhaps through an app or ROM, to install/activate ringtone alert?

-I am asking this because I have paired my device to a bluetooth GSM-enabling gadget and now using it as a phone (for more info about this gadget please look up gmate+ from skyroam), but I can't get any ringtone for incoming calls as the app that came with the device does not have the settings for it.

2. Is there an app/ROM that enables changing of lockscreen wallpaper only without the additional unlock options as given by some apps?

-I only want to have my lockscreen wallpaper change and still use the native/stock unlock method (facial recognition/PIN). I also do not want the extra unlock methods (double unlock).

3. (A real newbie question) Can I just flash a ROM to my device without having anything erase?

-I'm concern about having to reinstall apps and more concern that a new ROM will not be compatible with my gmate.

Thanks for taking the time to read, understand, and help out!

More power!

Hey everyone,

I purchased a Nexus 7 today and have had a major headache trying to get the thing to connect to my laptop (running windows 8) through either mtp, adb or fastboot.

-I have tried the stock cable and the cable for my htc sensation and nothing works.

-tried uninstalling and reinstalling ADB/fastboot drivers

-tried installing the official asus nexus 7 usb driver

-tried enabling and disabling usb debugging

-tried switching between mtp and the other one

-tried plugging in in fastboot

none of this made my nexus 7 show up on the computer in anyway, not even in device manager. tried all on my dads windows 7 pc too but nothing worked on there either.

On top of this the bloody thing will only charge via usb and the mains whilst its switched off! when its off and plugged in a moving battery level icon comes up but whilst on there is no evidence of it charging.

Am i stuck using it like this or is there a way i can fix this? Any help would be massively appreciated, i have tried everything

That's not right. Try using the supplied cable and wall charger, but that said I am using my HTC Incredible S cable with it and I don't have problems. Perhaps re install the drivers, if that doesn't work I am out of suggestions

What do you mean? Do you have CWM without having an unlocked bootloader? When you turn it on, does the google splash screen have a lock on the bottom?

If you used a toolkit it has already done fastboot oem unlock

Or are you saying you're a new user, and you want to know if you should unlock before you start playing, so you won't lose data? In that case, I would keep it locked so you can easily return it in case there is a problem
[Nexus 7 Q&A, Help & Troubleshooting] sportscrazed2:
What I mean is that I have a locked bootloader do I have to unlock it before upgrading cm 10? Don't know how it got relocked because it did. Edit lock shows up on Google splash screen but actually booting into boot loader shows unlocked status. Don't understand which one is it?

Hi rooting it does void your warranty but you can always put it back to original stock. I use wugfresh nexus 7 root toolkit.

Anything you do to change the operating system voids your warranty. Apparently taking off the back voids it.

I did do this myself when it got water inside the screen.... This was my own stupid fault lol. Luckily i still got it replaced for free.

As far as the rest of the warranty goes as long as they cant see you've tampered with the inerds you'll be fine.

Any questions feel free to ask. Oooh I'd highly reccomend using paranoid android ROM...had it since day one and it is awesome... Gets updated regularly and any issues are sorted within hours.

Problem finding server on Nexus 7

I have recently acquired a nexus 7 and am trying to set it up so that I can access my media server through the lan. I have tried using ES File Explorer and BSPlayer Free and neither one seems to be able to see the network shares for my server.

I can access my server from 3 different computers all running windows 7 x64. the server itself is running ubuntu server 12.04 with samba for the file sharing.

The nexus can see my laptop that I am writing this from and an ipod touch I have but is not finding the server either through scan or by directly putting in the address. I have verified the ip address and know it is correct.

I have tried these in the 2 apps

smb://192.168.1.65/Video

You can flash system or boot loader from fastboot

Get the bootloader.img from sparksco,s thread in development and then you can open to fastboot folder, command is "fastboot flash bootloader (name).img"

That's if the bootloader is the problem

You can flash system, recovery, bootloader etc with similar commands

Help! Screen replaced but still not working

First, I'd like to say that I checked the screen replacement guide thread and my particular issue wasn't there. Also, since this thread seemed to be more generally geared to troubleshooting I wanted to start here.

My fiancee dropped her tablet and the screen cracked. I bought a replacement LCD and touchscreen digitizer. I did the swap but the new screen isn't coming on. If I tap it, I hear noises that let me know the touchscreen is working. It even played music for me (that I had to figure out how to shut down since the screen in completely black). So, I'm a bit surprised to find that the touchscreen digitizer is working independently of the LCD (but I'm admittedly ignorant about this so...). Nonetheless, before I claim the part is defective or go to a repair shop, I wanted to ask if anyone else has ever had a similar experience and could lend some advice.

Thanks for your time.

Paranoid Android Grouper 4.3 problem

Hi,

Because this is is my first post I wasn't able to post in the PA thread.

I was wondering about problems playing media on this ROM for the Nexus 7 (Grouper). I've been on all the 3+ ROM with no problems until I started flashing the 4.3 ROM (3.91 and up). Basically, I can't play any thing from Youtube, Play Music, Pandora. They all load but will not play just get a spinning circle. However, when I push them to my Chromecast they work fine on my TV but when I go back to play on the Tablet it just returns to not playing. Play Movies won't load at all, the app just crashes. I can get Netflix to work though on the tablet. I've factory/cache wiped between all flashes and have tried uninstalling the apps and then reinstalling from market but it still doesn't work. I am using 3.98 on my Toro device with no problems at all.

Thanks for any suggestions as I'd like to be on the PA 4.3 ROM.

[Nexus 7 Q&A, Help & Troubleshooting] poondog:
Not sure but maybe look into the full stock images on google website and see what 3g has that wifi hasnt?

Apparently that's a kernel patch.. Meaning you have to compile the .c or whatever file into the kernel itself or export it as a module

Or maybe any chance that its blocked on your network?

Maybe you've got a dud battery. How old is the device? Which ROM/kernel?
[Nexus 7 Q&A, Help & Troubleshooting] sgt. meow:
I'd say it's more than likely an app issue. Since your browser works fine using the ethernet connection, your kernel components are okay. Try it on some other device using the same ethernet cable and others and if it works on other deivces, write an INFO pm to the devloper (Gameloft I guess).
