My trusted N7 (16GB) is having problems. I tried a bunch of 4.4.2 ROMs (Pure, Slim, Xeno, BSZ, Vanir) on my N7 and they were all very laggy and slow. I also went back to a 4.3.1 ROM using Smooth which also was slow. I always did a user/data wipe before installing a new ROM.
Now I am wondering if I have a hardware problem or if I should factory reset the device.
Any suggestions on what I can try next before buying a 2013 32GB N7?
thanks,
Scott
My completely stock nexus 7 is running extremely slow too. I'm thinking of doing a factory reset as well. Its starting to become unusable.

Were you using the stock Kernel from each of the roms you used?? Have you tried flashing a different kernel??
I thought a factory reset /full clean wipe was always necessary if switching from rom to rom.....

I did a factory reset and then installed Vanir ROM. This is more than just wiping the user space.
Working great now.

Wanted ask if it will be possible in the future to update to the official cm10.2 with reinstall and wipe. I ask because I got friends and family all on nexus 4's cm with Franco kernel and I should them how to update but I just don't want to have to reinstall because that is too many people around the world.
I am talking about updating like thru settings how I do with the nightly.

CM10.2 uses Android 4.3, while 10.1 use 4.2.
So no, it will never be possible, too many system changes.
For the most part, will be okay. I've done it a few times without any major undesirable effects.

I think it is possible if you flash bootloader and baseband! If it doesnt boot then do a clean install.

you dont have to flash the bootloader/baseband, thats just an option.
you can always try dirty flashing, usually it works, sometimes it doesnt. make a nadroid backup just in case. if it doesmt work, you can either restore your nandroid or wipe everything and flash.

Doesnt it cause problems sometimes if you dont have the latest baseband and bootloader?
I never tried to dirty flash a rom, only for updating CM10.1 nightlies I did. (And I only had it on 4.2.2, now CM10.2 unoffical)

I was able to flash CM 10.2 over CM 10.1 with no issues. Make sure to also flash the new Google Apps!
Hey all, I'm having a problem with my nexus here and its driving me crazy. Basically i was behind on updates and running 4.2.2 (Paranoid Android) until today. I decided I would upgrade to the newest Paranoid android 3.99 RC2. First off, i downloaded the stock nexus 4 images, and flashed em all through fastboot. Then i flashed the newest CWM (6.0.3.8 i think) and proceeded to flash PA.
But when i booted into PA, i had no cell connectivity as well as unknown baseband, imei, and imei sv, even though the baseband is clearly shown in fastboot (its 0.84). I tried reflashing the baseband, no luck. So i reflashed the stock google img's and my imei and everything came back.
So i tried a second time and it still didn't work. Seems like whenever i flash PA, i lose my imei and baseband.
Help me out guys
Anybody?

DID you do a full wipe before flashing?
I would be very careful and stay stock until you get an answer. Without IMEI your phone is illegal and won't work. I've stayed away from C /M as it's buggy and has too much trouble, like this.
Sorry

Try using latest TWRP
I got this last time I flashed paranoid android. I had to use the LG tool and download mode

If you are coming from 4.2 make sure to flash 4.3 Radio and Bootloader!!
Follow this guide:
http://forum.xda-developers.com/showthread.php?t=2389721
Yes, I did a full wipe, even the SD.
I flashed the full 4.3 stock Google image through fast boot first. So I should be totally up to date.
I will try TWRP and see if its the new CWM that's messing things up.

The CWM version you used has a bug which derps your baseband when you flash anything. Simple fix: install any other version of CWM or use TWRP, then flash everything again (radio, rom, whatever). This happened to a lot of people. You'll be fine.

I recently upgraded my ROM to the latest version. Wiped the cache and davlik, flashed the new rom and then flashed GAPPS. The rom boots and shows Android is Upgrading but after a few seconds, it reboots again and goes through Android is Upgrading again and restarts prematurely.
Also tried only flashing the rom without gapps but I am getting the same issue.
Did you wipe data or was it a dirty flash.

It was a dirty flash. Then since it failed, cleared data and system and flashed but still no dice. Flashed the latest Cm nightly and it worked. Been using it since. Might be a problem with the rom. One other person had a similar problem though there are some people who used the same zip but didn't face any troubles. Looks like Cm for now

Yea I know it sounds weird but not all phones are created equally. I had 2 galaxy s3's, one Rom would work on one and not the other. It's definitely strange.

Apparently, it's a recovery issue. I'm on CWM. People who have flashed it successfully are on TWRP. Will give it a shot over the weekend.

The problem was indeed CWM. Flashed fine with TWRP.

I'm using and loving thunderkat 4.4, but my wifi speed is abominable. Is there a radio or patch that can be flashed to help this? I did factory wipe prior to installing even thoug coming from tk 4.3.
Thx

I have this problem also. Jumping onto the Note 3 and no problems so it's definitely 4.4. Have factory reset and cleared internal memory so it's happening to a clean slate.
Yup. On speedtest I'm now getting 20mb/s but yputube still stutters like a mofo. doesn't on my phone. Have tried clearing data for youtube. No different

Every 4.4 rom I've tried for Manta has this issue...
But 4.4 on my Nexus5 is fine on wifi
I sideloaded 4.4.1 yesterday and it seemed to help quite a bit. Now they've just released 4.4.2 so I'll try that later after work...
Hi guys sorry if the thread already post before. My nexus has 4.4.2 rooted and already install twrp. I play game a lot on my nexus 7. But after upgrading to newest ota feel so lag when i try to play shadow gun dead zone. Is there any way how to fix it. I thought it was my wifi problem but when i switch to my old motorola phone it works like a charm.
Thanks in advance

Go into recovery and wipe dalvik and cache.
If that doesn't work, a backup of your apps to your pc hard drive and then a factory reset usually helps, but do the dalvik wipe first so you don't have to reinstall your apps and see if that works first.

But did the flash do a wipe of everything? If so, that's probably why. I'm on stock 4.4.2 and I don't have lag.

I wipe dalvik cache, and data. I m afraid to wipe system. I m not familiar with twrp. So only wipe does thing.
My nexus had a soft brick before when i update to ota and thats give me nightmare. So what would you suggest, do i have to wipe again dalvik, data system? Sorry for noob question but the lag just still there after on day flash from the rom.
Thanks
