maybe can install WIFI analyzer to troubleshoot.

For mine, after clicking update, it automatically reboot into twrp and flash itself. then it auto reboot too. Maybe u using CWM, so different process.

Well, maybe u'll nid to flash it urself from 4.4.3 to 4.4.4

here's the xda link.

Not sure. Didn't flash the wifi tether and enable sms to try it out.

if u using twrp, juz dl the link from 4.4.3 to 4.4.4 from the xda link, and manual flash~ datz what I did for updating 4.4.3 from 4.4.2.

just flash the zip file. I'm not responsible if anything happen to ur device, but diz is how i usually do it.

Since ur new to flashing. U have twrp installed right?

1) If u are on 4.4.3 (KTU84L) and u wanna update to 4.4.4 (KTU84P), just download the link for KTU84P from KTU84L. Remember to download the correct 1, since there is 2 version, nakasi or nakasig.

2) put the zip file that u've downloaded into ur Nexus 7. Rmb the directory where u put it.

3) boot into recovery, twrp in ur case.

4) tap 'Install', find the zip file that u've put in ur Nexus 7. Rmb the directory where u put it just now?

5) swipe to confirm flash

6) wait for it to flash, after flashing, choose reboot.

7) updated to 4.4.4

the steps above ONLY works if

1) u are running on 4.4.3 and u wanna update to 4.4.4
2) u are using twrp as custom recovery
3) u downloaded for the right version, wifi or 3g

not much noticeable changes. based on google, they juz wanna fix some security issues.

hmm..sumthin went wrong with my Nexus 7C gps. I turn it on, tried all 3 mode.

Used GPS Test and GPS Status to check, but it juz could not detect gps at all. GPS Status just keep 'looking for GPS location', while GPS Test has no result at all. No bar at all.

B4 diz my N7 gps was superb. can lock in very quick and stable.

Bug from 4.4.4?

I dun think Asus provide international warranty. If u nid RMA, nid to send back to USA i think.

wah...dat is too long dy...for the original charger I think nid to buy from Asus store. Maybe nid to order. But iinm, the original charger is 2A. So if u buy a charger which is rated at 2A, then it shud charge at the same speed like the ori charger.

U guys still using ur N7? Or sold it or letting it sit in ur drawer collecting dusk? Lel

Last time i bought it for gaming, reading pdf file, wifi tethering and gps. But now i finish my degree dy. No longer reading much pdf. After changing phone from Galaxy SL to mi3, my mi3 gps and gaming performance is much better than my N7. After buying a mifi, i no longer use N7 for wifi tethering too. basically its collecting dusk in my drawer.

Such old model and specs dy. What u guys using ur N7 for nowadays? Any idea how to put my N7 to gud use? Lel

lel. hope the Lollipop update will bring back some life to this thread. Now my Nexus 7C is for my gf to play her Farmville 2. She say bigger screen, nicer to play.

Maybe u shud do a clean flash, try clearing Dalvik Cache too. Might be smoother.

Waiting for the 3G version's factory image. Time to do a clean flash.

If ur lucky, it will work, but there'll be some error. Maybe some of the function not working.

If ur unlucky, bootloop.

lol. of coz never tried b4. It's best not to flash the wifi version on ur mobile version. Coz some files might be missing in the wifi version.

I've flash plenty of things on my N7 before. Worst case is bootloop ni, never brick it b4.

did u wipe dalvik cache?

Try to back up ur data with twrp or cwm, then do a full flash and see if it's better.

Still waiting patiently for Nexus 7C's factory image. zzzz

Considering to sell my Nexus 7C after updating to Lollipop. lel

U guys have to wait for MX player's dev to update. No choice.

I rmb last time oso lidat. From JB to KitKat, MX player not supported. Then once there is an update for it, it'll work for the latest version.

did it show any battery icon when u try to charge it?

Last time my Nexus 7 turn off after reaching 0% battery, cannot turn on oso. Have to plug in and charge for a few min, then only can turn on.

i think it's best to send to Asus service center then. Might be prob with battery, or display. Maybe it was turned on, but display not showing anything.

I think u sell it oso can get RM300 lidat if u are using the 32gb + 3g unit.

Depends on u, if u still nid a tab, better just get it fix and continue to use it. Got Lollipop update yo.

last time for me, it could not turn on at all, maybe I left it in my drawer for too long since I was not using it.

Have to plug in and charge for a few min, then only the battery icon appear. Then after a few more min, then only able to power on.

those that get OTA to 5.0 is wifi version. N7 2012 or 2013 mobile version xde update yet. even factory image pun xde lagi. I everyday checking it here.

If got dy I'll surely do a clean flash on my N7 2012. But duno why 3g version no OTA or factory image yet.
