Nexus 7 Stock 4.2.2 - Signal Icon? - Nexus 7 Q&A, Help & Troubleshooting

Hey guys. Recently got a new Nexus 7 and I love it! It had 4.1 installed so I flashed official 4.2.2 image and now, there is a signal icon in the taskbar. Is there a way to disable this? Whenever I go to auto-update an app, it also complains about auto-updating may incur charges over data.. but the Nexus I got is supposed to be a WiFi-only device?

Make sure you have installed a proper image, there is an images for WiFi model and 3g model.

why always me said:

Ah, I see that now. Is there a way to re-flash it without having to wipe the device?

If your bootloader still unlocked then yes flash any custom rom using any recovery like cwm without wipe data we call dirty flash but however do it on your own risk it may cause many problems after.
or if you want to stick with stock you may using fastboot to flash only system.img and boot.img.
With bootloader locked there is no way to re-flash without wipe all data.

[Help] Lost my 3G after flashing 3.2.2

All workt realy good with Tiamat 2.2
Then I got the less awesome ide of trying the new 3.2.2 update.
Now the crazy thing happend I lost all my 3G.
So I figured if I flash back to Tiamat it might solve the problem, but nope
and I tryed flashing back to stock and still no 3g.
Anyone have an ide of what I mest up and how to fix this.
Did you flash the stock rooted 3.2.2 that tells you that you will lose 3G if you do???
flash back to 3.2, and it should come back, but 3.2.2 is for the ones with the 4g chip installed.
yea I must have mist that, but when flashing back or to stock I dident get my 3g back, Gonna trye flashing some more (Got all day)

I have no 3G now either.
I received my Xoom back fro the 4G upgrade yesterday, unlocked and right before pushing su and superuser files I started bootlooping.
I re-locked with instructions on Motorola's website which got me back to 3.0 but I cannot connect to 3G now (I'm not in a 4G area).
I've tried flashing nand backup after rooting 2nd time but got bootlooped again so re-locked again.
I did all the OTA upgrades and am at 3.2 now, but still have no connectivity. WiFi works fine...
Anyone have suggestions?

Flash via fastboot same as stock images.
adb reboot bootloader
fastboot flash boot boot.img
fastboot flash system system.img
fastboot erase cache
fastboot reboot
May need to wipe data, don't forget to erase cache. 4G and WiFi working on my xoom with these images and it should already be rooted. Let me know if it works.

i guess i should ask which rom did you flash from? did you go from the stock and rooted 3.2.2 rom from the dev thread? or from a complete stock factory image?
Does it have the lte/cdma with in networks? And do we need to have a custom recovery? If it is rooted can I go straight from stock 3.2.2?
Sent from my Xoom using xda premium
I just applied this and no LTE/CDMA option.
So under mobile networks there is no setting for you to switch? Then this is not the most up to date version.

There is some version that the LTE devices ship back with labeled 3.2.2, but it does not look like what others have posted all over the net saying 3.2.2. Not sure what the deal is but I just got Verizon to do a warranty replacement on my Xoom LTE. If someone can explain to me how to export that Rom when I get the replacement device I will post that for everyone to have a look.
I'm too stuck in this boat as well.
I received my Xoom after the LTE Upgrade and flashed the 'Stock 3.2.2' Rom and started having all the wifi issues. I thought I remembered my 3g working with this ROM but I honestly don't know if I'm remembering right.
Anyway, I tried going back to stock but obviously, no one has the actual latest build. When I received my Xoom back, I absolutely had the option of choosing LTE/CDMA and none of the images and ROMs floating around right now have that.
The problem I'm having now is my 3g doesn't work with ANY ROM or or image I've tried. This includes stock 3.0 and all the updates, the Stock 3.2.2 ROM, Tiamat, the image in this thread of the nandroid and the Pilot 3.2.2 image going around.

As far as I know there are 2 versions. HLK42B and HLK75C. Both for the same 3G/4G VZW Xoom's, one is just an earlier build from the pilot group from what I can tell. I do not know what other differences there are between them.

What ROM I flashed from is irrelevant, but it was the earlier HLK42B biuld I mentioned before which was infact stock/rooted 3.2.2 to these HLK75C 3.2.2 images.

It does on mine. Although after a factory reset it is having trouble connecting to 4G, I am working on that now, but it does still have the LTE/CDMA option.
Hey I just got updated to HLK75D. I am unrooted and locked, but if you want the files tell me how to get em and I will.

I agree with AceXMachine's post above. I do believe that there is something wrong with my Xoom. The whole reason I'm having this ordeal is because I lost my 3G/4G connection all of a sudden and during troubleshooting with Verizon and Motorola things have gone down hill over the last 24 hours.
One question for AceXMachine I have is can you connect to 3G? I saw you posted you are having problems with 4G.
Same Problem with Connectivity as many
I sent my Xoom off for 4G upgrade and received it. Moto in its infinite wisdom sent me a new Xoom. So naturally, I started my Xoom and 3G/4G failed because I had a new MEID. Motor provided this new Xoom without syncing up with Verizon. So Verizon didn't have my MEID synced to my new 4G card. This explains the connectivity issues I had OOB.
I wish I new that before I went about a variety of flashing that failed in one way or the other. I did eventually get things to run with 3g/4g, and here s what I did.
1. Flash HRI66
2. Do a hard reset from Settings/Privacy
3. Reboot and fastboot flash recovery-Tiamat-R4c-100611-1150-cwm.img
4. Reboot into CWM and flash Android-HC-3.2.2-Stock+Rooted-1.1-SOLARNZ.zip
5. Flash HLK75C from this thread above as directed
Upon reboot both my WIFI and 3G/4G were restored.
When you reboot you should get prompted for HLK75D which is the market.
Peace & Joy

Sorry I missed your question. I lost 4G and 3G but it turns out it was because of a kernel I had installed and didn't realize it til later because I was using WiFi. Reflashed and I was good again until I tried installing that same kernel I was testing out...forget the name...Rogue/Arcturus or something.

Root but stock

I've always rooted and flashed roms on my phones. Everything from the sweaty palmed s-offing of my Desire to the simple fastboot commands on my Galaxy Nexus. I've then always gone on to flash roms at least weekly.
I'm about to buy a Nexus 10 and feel like leaving it stock but rooting it to be able to use stuff like Ti backup etc. Is this as straightforward as the GNex - fastboot unlock and fastboot flash su.zip?
I want to still have OTA updates though, does this mean I need to keep the stock recovery and is there a 'root keeper' app?

There are different methods, but if you want to stay on stock, use superboot method. You just need to install a drivers on your pc, and double click a file. You don't need to be unlocked or anything. Search for Nexus 10 superboot on the search button.
Btw I recommend you, if you still don't have the nexus 10 and plan to flash roms, you should use wugs toolkit. Root, unlock, install twrp (custom touch recovery) and in case any day you want to flash a rom, you won't need to unlock and lose your data. Just make a backup and you're ready to go.
Superboot: http://forum.xda-developers.com/showthread.php?t=2003938
Wug Toolkit: http://forum.xda-developers.com/showthread.php?t=2015467
If you want to still have otas, then just use superboot, you don't need to keep the stock recovery but to avoid problems keep it. Just make sure before use ota, you haven't changed any file in the folder /system. For example if you place the aosp browser in /system/apps, put the original files on there, flash the ota, and then put the aosp browser files again. And yes, on the google play there's root keeper and it can be used on nexus 10.
Thanks. I should have the drivers set up on my pc unless I need Nexus 10 specific ones. This was the biggest pita lat time.
Doesn't installing a custom recovery stop OTAs working?
Things is, you're right. I know I'll probably end up flashing a custom rom in the end.

Nope it doesn't. Once the ota shows up, and reboots to recovery, if you have a custom one, it asks if you wanna keep it.
Thanks. All I know is on the Galaxy Nexus the OTA can fail if it detects a non-standard recovery.
Maybe its a CWM thing?

Updating with unlocked bootloader

Hello im on stock 4.2.2 and im rooted with an unlocked bootloader. Will i have to relock it once the new 5.0 klp update comes out to get it or will it still work fine? I know theres still a while until the update but id like to be prepared
Depends, if you want the KLP version from google, you'll need to go back to stock and lock the bootloader.
However, there's a 99.99999999% chance someone here at XDA will have a KLP rom before google officially releases one for our N10s.
Ok thanks but can i keep it rooted or do i need to unroot aswell?

OK so I heard some rumors about a jellybean update to 4.3 soon. I really don't want to lose all my data by flashing a stock image once it comes out. Is there a way to relock the boot loader without losing data? And if not is there a way to backup all my data and restore it afterwards. I tried using wugs toolkit to do this but the problem is it only backs up the main user and not the secondary ones. Any suggestions would be appreciated thank you.
Sent from my Xperia Play (r800x)
I believe unlocking/locking the boot loader will in fact wipe all data. So you'd have to manually handle the backup/restore if you don't want to lose the data.
I'd try something like TB to backup and restore. I usually start from scratch again as I've read restoring app data can cause issue under certain circumstances. YMMV...

Haha.. No problem.. Although, if you are on a custom ROM, I'm pretty sure you will have to flash a stock rom before you do the OTA... If you are on a custom ROM it will be better to wait for the devs to update it themselves...

I'm not sure so far all I've heard is that you have to lock the bootloader first... And I'd rather not take the risk. Anyway that app mentioned earlier locks and unlocks your boot loader with a click so its great
Sent from my Nexus 10 using xda app-developers app
hmm, from reading that apps description it gives me the impression a bootloader could be locked again w/out wiping - its just then when you would want to re-unlock that it would re-wipe.
right now Im unlocked but stock everything else. I think I will see what happens just trying the upgrade w/out relocking (again because Im pretty sure that's the same as the .2 I just did.)
if anyone can confirm any of this it would be welcomed

To get any Google OTA you do not need to re-lock the bootloader. You might need to flash the stock recovery prior to install the OTA.
At least this is what I did. Of course, to be safe I installed "Bootunlocker", "Voodo OTA Rootkeeper", and "SuperSU".
SuperSU gives permission to keep your phone root when you flash stock recovery.
After you re-install a custom recovery you need, prior to reboot, to wipe "Dalvik-Cache".
The long wait can start
@gunner1937 OK thanks. But where can I get stock recovery? Also I already have super su installed so do I need to do anything before flashing stock recovery or I just need to have supersu installed and then flash to keep root? Will flashing stock recovery wipe data? And are there any other steps I need to take. Please explain thanks

To get stock recovery go to https://developers.google.com/android/nexus/images.
Download the factory image for Nexus 10 "mantaray".
Extract the files using, preferably,7-zip.
In the extract files select the file with extension.tar. Unzip with 7-zip.
Open file " mantaray-jdq39". Click on file "image-mantaray-jdq39.zip: this is where you will find all the img files including "recovery.img"

Are you rooted? If so and you have a custom recovery, I would do the factory reset via the recovery, that way you should still have your apps. If not, then you will lose everything and have to start from scratch.
Could be due to one of two things or a combination of things. One is a hardware issue, which I hope isn't the case. I would check the apps first before resetting, then do the reset. If it continues, try re-flashing the stock image. If after that and you're still having problems, going to 4.4, or 4.3 since it started with 4.4.

If you flash stock, it WILL wipe out everything unfortunately. If you at the least had an unlocked bootloader, you could have flashed the ota.zip and kept everything intact.

Wifi stuck on "Turning on", even after reflash

Greetinga, xda denizens!
So I tried the LTE Flasher App for my Nexus 4, flashing hybrid modem files in order to enable LTE on my phone, but since then everything seems to be broken about my phone and most importantly wifi is stuck in turning on.
I tried factory resetting and flashing new kernel (Cyanogen 10.2) but that didn't help.
Is there something else I can do? I thought that wiping and reflashing is the most brutal thing you can do to fix what's wrong with your device.
Thanks for any help,
Adam

Flashing a kernel doesn't flash modem, you need to do that manually. Download a stock modem from xda/google and flash it using fastboot. I don't know if it's related to wifi or not, but it's worth a shot.
Yup. If the radio you flashed is faulty a factory reset/ROM reflash/kernel reflash won't change a thing. The radio is a separate partition and 99% of all Roms come without a radio partition. As mentioned above, download a stock radio from here and flash it. Should fix the issue.
