[Q] Nexus 7 3g (2012) - Bad 3G reception after 4.3 update - Nexus 7 Q&A, Help & Troubleshooting

I recently purchased Nexus 7 3G..
It was having 4.2.1, I recently upgraded it to 4.3 using fastboot.
When it had 4.2.1, 3G was working awesome(1.5Mbps).. after upgrade very bad 3G reception(10Kbps).
I googled, many people are having the same issues, but no one had the solution to fix it.
Any one here knows how to fix it ??
If no one, can I revert back to my older version 4.2.1 ??
Thanks in advance

I also recently updated to 4.3 and there is no issue with 3G. I think it was the network problem rather than 4.3. If it is the problem of 4.3, Google will fix it soon.

[Q] iPlayer on 4.2.2

Since installing 4.2.2 on my Nexus 4 and 7, BBC iPlayer is no longer working. Has anyone else had this issue? Is it an issue with the new ROM or iPlayer?
Thanks
Likely an issue with BBC. They did the same when 4.2 came out and issued an update fairly soon after.
If you can grab it from a 4.2.1 backup it'll likely work

I restored the app from a backup and get an FC whenever I try to play a video.
Works fine for me. Stock 4.2.2 and Franco kernel r83.

[Q] Best way to get LTE on Nexus 4

I recently switched from a Galaxy s3 to a Nexus 4 and would like to get LTE on it as Rogers does not support DC-HSPA 42Mbps. So far from all the threads i have read say there are a few ways to do this:
1) downgrade to 4.2.1
2) Flash 4.2.2 with the .33 Radio.
3) custom Rom 4.2.2 with .33 Radio.
From what i gathered people who flashed .33 radio (or older) on 4.2.2 have been having a range of problems. And apparently 4.2.1 has a lot of bugs in general?
It would be great if someone who has already done this could post about their experience with each of the options as i'm tired of reading pages and pages of posts about how the Nexus 4 is not suppose to have LTE and to be happy with the hspda etc.
Thanks
I am also interested in this any advice would be appreciated

If you happen to lose the ability to make or receive calls on your Nexus 4 on the .33 baseband then you must flash the latest .48 baseband to make calls.
I am going to flash a 4.1.2 ROM when I get home I had a nexus 4 when they first came out running lte went to a note 2 and now back again to nexus 4;I am running the latest paranoid android 3.1 and faux kernel but the internet is painfully slow without lte I really can't take it any more will try 4.1.2 then 4.2.2 with the different radios

I am almost positive that there is no backwards compatibility with Android. Meaning, that since the Nexus 4 debuted with 4.2, you couldn't run a 4.1.2 ROM, and that's why they don't exist (to my knowledge).
to anyone interested i flashed a .33 radio from paranoidandroid 3.1 / latest faux kernel and i now have lte back - now everything is good !!

You're able to make and receive calls using the .33 radio with the latest update from PA?

golfinggino,
Could you be a little more clear/descriptive? What ROM/kernel are you running now? Are you still running 4.2.2 stock or something else? Did you follow instructions that you found somewhere?
Thanks in advance,
JT

Yes was running the latest paranoid android and faux kernel wasn't happy with it and just flashed the latest carbon ROM ( much better) along with today's faux update, lte is working on the this ROM as well
i made and received some phone calls and didn't notice anything unusual, i will test making and receiving some calls tomorrow
Sent from my Nexus 4 using XDA Premium HD app
tested it today and the call quality seems to be better on the .33 radio then the latest one ? could just be me ? anyway ran on lte all day was connected to wifi for bit and still managed 5 hours screen on time - just picked up a nexus 10 today and in the process of loading up carbon rom on it - that should really fly !
hey again guys thanks for all the responses and sorry about the late response.

I think im going to try the Carbon rom too. Did you have to flash the older radio with it or no? sorry im new to flashing roms and radios and such.
Thanks again guys will post again with my results (hopefully wont mess up my phone in the process XD)
yes i flashed the older radio - the one i used was cwm-radio-mako-m9615a-cefwmazm-2.1.1700.33.zip
i was running paranoidandroid 3.1 but think the carbonrom is smoother
Only problem is that at least on cyanogenmod using any radio other than version 48 causes auto focus in the camera to not work.

What the heck....that is so irrelevant. There is absolutely no relation between the camera application and the baseband. It has to be a CM 10.1 rom issue.

Test it for yourself. Many have had problems with autofocus on .33 radio. Updating baseband fixes that issue. And if updating the baseband fixes it, by definition it's not a cm issue.

4.3 update

I have a nexus 7 which is rooted with wug fresh toolkit. It shows i am running 4.3 jellybean. I just got an update yesterday that the tablet wants me to install that is for 4.3 jellybean... The notification is in the upper left of my screen and wont go away. Not sure what to do or why its asking me to upgrade to 4.3 because i have it already. Should i install it?
thanks
It's a patch for several problems created by the 4.3 update.
Sent from my Nexus 7(2012) that has zero issues.
But since your rooted it won't update. There is a thread in General Nexus that explains and has solutions.

I too have a nexus 7 (2012) rooted with WUGfresh. It runs fine while 4.3 seems to have all sorts of problems on the Nexus 7 (2013) which is already on update #3. So I'm reluctant to upgrade to 4.3 till they solve its bugs.
What essential improvement does 4.3 bring over 4.2.2?
Ok thanks everyone, ill take a look for the other thread

[Q] Updated non rooted Nexus 7 to Kitkat and touch stopped working

Hi I have a non rooted Nexus 7, I replaced the screen a few months ago and everything was OK. This weekend I got OTA Kitkat and after restarting the touchscreen just stopped responding.
I guess the screen frimware is not compatible with kitkat, is there any way to go back to 4.3? Or how do I change the screen firmware?
Thanks
My nexus 7 2013 upgraded last night and then touch screen seems less sensitive.
A reboot seems to have helped.

I got the kitkat ota on my 2012 nexus 7 3g and the screen seems fine here.
Edit: sorry I don't know if you can safely go back to 4.3
