[Q\Help] Nexus 7 ROM issues. - Nexus 7 Q&A, Help & Troubleshooting

I've got an unlocked & rooted 1st gen 32gb WiFi nexus 7 running 4.3. Each time I boot into twrp and wipe data/cache/dalvik and flash a ROM it bootloops. I've tried 3 different ROMs to no avail. Any suggestions?

Do factory reset - system, cache, davlik, data and then install rom

Encryption with Cyanogenmod and CWM recovery

Folks, what's your experience with using encryption and CWM recovery along with Cyanogenmod ? I came across different conflicting reports with regards to issues with being able to use recovery after encryption.

What rom are you on? Try reflashing ur ROM, then wipe cache and dalvik cache.

Wipe the data, cache and dalvik cache.
If that does not help then you need to flash the PA stock kernel from here: http://goo.im/devs/paranoidandroid/roms/mako/pa_mako-Kernel-4.3_JSS15J_GOOGLESTOCK.zip

I know that, but I wasn't sure if they were on PA when they flashed the bootloader/radio.

Best to ask that then, the previous question did not even refer to the radio and/or bootloader.

Guys im using RasbeanJelly + Matrix kernel, i wiped data, system, both caches and still i get stuck in the Boot Animation

Android is upgrading and then bootloop...

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.

Wifi in 4.4

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...

Nexus 7 lagging after update 4.4.2

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
