Camera failed to launch

Guys can anyone help me?

This afternoon I try to open the Camera app but it won't open and it said that 'Camera failed to launch, please reboot your device and try again'.

When I used my phone in the morning, my camera work just fine.

I reboot and nothing happened.

I googled, and do some wipe cache in recovery mode still nothing happened.

I disabled for a while and install a 3rd party app (Google Camera) it said that it can't connect to the camera.

I can't even open my Snapchat.

Is it the firmware or a hardware problems?

Now should I flash some new ROM?

Fyi, I just downloaded 2GB of Need for Speed game, does it crash with the Camera or something?

My device is running in

Build Number: LRX21V.WW-ASUS_Z00A-2.20.40.97_20150917_1572_user044030427_201501060109

Baseband Version: 1527_5.0.35.1_0815,1527_7.0.20.0_0723

I haven't root it yet.

Sorry for bad grammar.

Any information and suggestion will be very helpful.

Z00AD Root help/ Fail

So I got a new Zenfone2 Deluxe. Super excited - was going to root it now and then load CM whenever that becomes official.... The phone, absent the bloatware, is great.

Problem is I haven't been able to root it.

- I updated to the latest .97 release

- I used the official unlocker.

- I turned on debugging. I turned on MTP and I tried it off.

I have tried Windows, Ubuntu, Arch Linux using this method: the one click root from shakalaca

On windows it gets to the last "waiting on device" and then the zenfone boots normally.

On both arch and ubuntu it hits a syntax failure and dies....

Any help would be appreciated.....

My question is about clearing the cache partition from recovery. I am not unlocked or rooted.

As far back as I can remember after you clear the cache partition then restart the device, before the launcher executes a box would show that said it was optimizing Android program 1 of XXX but when I do this on my zen2

That does not happen. Is the cache really cleared?

Hi guys, I'm experiencing some problems with a feature on my Zenfone 2 (ZE551ML): the "Shake Shake" function from the Motion Gestures no longer works. I bought the phone about one month ago, managed to use the feature for a few times, and it just stopped working at some point, and hasn't worked since.

It is not a crucial feature, but I don't like the feeling of knowing that something that should work doesn't.

My phone is not rooted or anything like that - it's just like it came out of the factory, except for the fact that I installed all the OTA updates available. The feature stopped working before I made any updates, so I think I can rule out the updates as a cause for it.

Let me know if you need any further information :)

Looking forward to a fix.

From online I understand that the ZE551ML is the 4GB RAM version and the ZE550ML is the 2GB RAM version.

I bought the 2GB 16GB model but on the box, it says ZE551ML and in the phone info settings it says I have the Z00A (ZE551ML). Says the same in the bootloader (Z00A/ZE551ML).

I know i don't have the higher end model because the storage in settings is 16gb and ram in applications settings is 2gb

I am confused, which version do I have? I want to flash a custom recovery but I want to make sure I download the right one
[ZenFone 2 Q&A, Help & Troubleshooting] rseiler:
Your first statement is incorrect. The ZE551ML is available in both sizes (though the 2GB one is so difficult to find these days that I wonder if it's being phased out in favor of the ZE551ML model recently introduced that's otherwise the same as the 2GB one except that it has 4GB--not to be confused with the higher-end 4GB model that has more storage and a better CPU).

Hello everyone,

I got a problem with my Zenfone 2 Z551 ML it seems that the wifi is very weak I can't detect any connections from an another room and i get only three bars when i'm next to the router.

I tried to install paranoid android and cyanogen and did a full wipe before, nothing changed.

I can't go back to the stock rom because when I try to sideload adb tells me that the device is not detected even with the drivers installed.

I'm currently downloading the Super Zen Rom and hoping that it will solve my problems.

Any suggestions on what can I do to fix this wifi problem or on how I can go back to the stock rom ?

Hi All,

I recently purchased a Zenfone 2; I wanted to keep my original numbers, so had to go from normal sims to micro sims. with sim 1 I put this new micro sim in too early instead of waiting for the old sim to be deactivated; And with the other sim i waited until the old sim 2 was deactivated before inserting into the relavent sim slots. The problem i have is that the mobile phone now displays the numbers which came with the new micro sims and not my existing numbers. How do i correct the display so that sim 1 & 2 displays my true numbers from my old phones?

Your help in this matter would be appreciated. Thanks in advance.
[ZenFone 2 Q&A, Help & Troubleshooting] wutr:
Are you sure the location settings are still set to "high accuracy" (Settings > Location > Mode)? This uses a combination of mobile network, wifi and GPS to get you a quicker location fix. Also, A-GPS (which requires you to have an internet connection) helps by downloading the positions of all the satellites so that your phone knows which one to look for. I don't think you can control any of its settings, but having data on and setting the location settings to "high accuracy" will speed up getting a location fix.

You would have to get your provider to transfer your numbers over to the new sim cards, contact your mobile network, they should be able to help you out.

[ZenFone 2 Q&A, Help & Troubleshooting] wutr:
Make sure you're in the directory where fastboot is located before trying to run it.

ie: "cd c:\temp\fastboot" or wherever you may have your fastboot executable located. It probably came in a zip file from the TWRP thread, so cd into the directory where you unpacked all those files.

Please Please Help

Hey I have one or two questions, I've softbricked my phone....and ADP doesn't work

I have a Zenfone 2 that was CN Z00A 2.20.40.63 , I tried to root because random chinese apps kept downloading on my phone and obv it soft bricked (kept looping at boot)... I went to the recovery mode but ADP couldn't find my phone and then I loaded a recovery image on my SD calling it MOFD_SD.ZIP but that didn't work due to signature verification error.

Now I'm thinking of flashing a pre-rooted rom as I see fastboot is recognizing my device....I would go through with the process but I'm afraid if I screw this one up it could be the end of fastboot working and therefore me being royally screwed.

Since my phone was naturally CN Z00A 2.20.40.63 I'm wondering if the pre-rooted images on this site (mega.nz/#F!k4MHiAgL!dVuOKeH3eokcwPSNI79ffw) will work?

There is no download for CN Z00A 2.20.40.63 and I want to know whether it's safe to use CN Z00A 2.20.40.61 or if a WW image will work. (I have read elsewhere that an older version will not work)

If anyone could reply with help it would be greatly greatly appreciated.

Additionally my brother has a rooted Zenfone 2 running on the same as what my phone was (CN Z00A 2.20.40.63), is there any way that he could get the necessary files I need off his phone?

TL/DR

1. Only fastboot seems to work, if installed a pre-rooted rom do I need to find a firmware equal or newer to the original? Does it matter if I was to switch from CN to WW (as I cannot find a CN version that is equal or newer)

2. Is it possible for my brother with rooted ZF2 on same version to get necessary images to flash off his phone?

Did you enable USB Debugging? If it doesnt work that way, then you can enter the bootloader menu manually.

1. Power down your device

2. After the screen is black, hold Power button and Volume Up buttons simultaneosly

3. Leave the Power button when the phone vibrates

4. The leave the Volume Up button when ASUS logo appears

Now you should be in the bootloader menu and can continue the fastboot process.

Looks like now you got a broken fastboot. Maybe you flashed a corrupted image of the recovery or droidboot img(s)

Curious but before doing all this did fastboot work fine? Were you able to go to the recovery mode and clear cache? And if you used the fastboot commands, which order did you used them?
