you might be able to solve it with a kernel. there are kernels from franco, faux, motley, intersectraven to a name a few.

I would recommend you read the OP of each kernel first, and use the stable version of the kernel, and the appropriate version for your setup, which is AOSP.

do remember to flash the stock reset kernel zip file from either motley's or faux's page if you are changing from a custom kernel to another, or if you want to just restore the stock kernel.

hm benny, this thread said that there is no efs partition for nexus 4, how did you backup yours?

another possible way, is to reflash the stock images (you can stick to 4.2 images if you don't want the battery drain bug in 4.2.1)

in the xda thread (the great battery life impression) a few folks like undercover, and jeff mentioned that re flashing the stock images improved their battery life. they said something about incomplete firmware installed in the device during the manufacturing. kernel is different than firmware. so that might help too. they thought it was a placebo effect but they did noticed an improvement. they recommended using efrant's manual way, because you'll have full control of the process.

if that still fail, then request a replacement unit, might be a faulty wifi chip after all.

according to the response here http://code.google.com/p/android/issues/detail?id=40065 ..it seems that version 4.2 and above are having such problem..is it because of firmware issue on 4.2?

Is it normal that, when there is no data or line~~ it will switch to R? As in roaming?

Anyone tried the kernel above? I am using franco r34 + pana android ROM but battery life seems bad... 1hr 10minutes of msm_hsic_host of wakelocks, killing my battery like water.

BTW, if flash from franco kernel to the kernel above, need to flash back to stock kernel first? And my data/apps will it be gone? Thanks

I just read further, the author said franco kernel used non-stock ramdisk and will cause bootloops if flash directly... I'll try flash to stock kernel first then.

Very satisfied with aokp, just enough customization + stable + smooth. Look at my Nav bar
6 buttons all together. now i don't have to use power button to lock screen. and can use volume rocker to wake phone. Just what i need in a ROM. 

No choice... kena FFK

No need to reply if you don't bother to help dude. I know garage sale got plenty. What I want is a shop in PJ area with those stuff. Shop. Get it?

huh?

just to confirm - do u mean after i unlock and root, if i ever want to upgrade my stock OS JB to 4.2.2 or later i need to lock it back???

open the motley link at my signature and search for reset. this reset kernel zip file is used if you are using stock ROM with a custom kernel, and you want to restore back the stock kernel.

Thx for the explanation..
No bootloop?

TBH, N4 is the first device that i see that have to use all this reset kernel thing. from what i read this is because of the different ramdisk used by franco

i like to play safe and just follow the steps given by the kernel devs

newbie in flashing kernal. What procedure to do if I want to flash franco kernal with stock rom? Root->cwm->flash boot_image?

hi guys if i want to flash franco.kernal it will wipe off the phone right?

anyone is letting go of their Nillkin rear cover SP protector??

Guys is this phone worth getting? Been using samsung smartphone for 2 years dy.. I checked out the digi SC today they show me the plan with rm200 rebate.. I only need to pay rm1299 upon registration.. Monthly rm68 with 5gb quota.. So is it worth getting? Thinking of getting new phone fore CNY.. Haha..

even i go to setting & sync my gmail the new email notification is not coming out

One question: If i flash franco kernal and stick to stock rom (4.2), can I upgrade my OS to 4.2.1 without flashing my kernal back to stock? Can I freely upgrade my OS to 4.2.2 in the future?
