Help Pls

Does anyone know when I'm trying to Flash the Eng-Release to the Slide why on step 6 I get permission denied or cdmod not found?

I don't know specifically to this but yesterday while I was rooting I had that happen. I was pushing some files through adb and told me no permissions. I did reboot on phone and computer and it worked the next time. Weird. You may have already tried that but that's all I got and like I said it was not for this specific step. mine was during the root process.

If you are actually typing "cdmod" that is why, the command is "chmod".

Need Xoom WiFi boot.img

Looks like the boot.img on the WiFi only model is slightly different. Flashed the rooted boot.img file and now I'm stuck at the Dual Core technology screen. Anyone have this available. All help greatly appreciated!
UPDATE
See thread -> http://forum.xda-developers.com/showthread.php?p=12432218

Can someone post the stock xoom wifi dump of the boot.img, recovery.img, system.img, and userdata.img in case something happens?
Apparently it looks like its slightly different than the wifi+3g version. Also is the overclocked kernel file working posted by coolbho3000?

i need the answer too... i m comfused.

Alright I have a stock Xoom tablet now Just gotta figure out how to pull the boot.img file off. Any ideas and I'll do it ASAP.

No clue mate. From my knowledge you have to be rooted, or have the SDK on your pc. I think. Neither which are available as of now

So is the wifi only version able to be rooted as of now?

currently, yes. We need a new root method. Well I would not say a new "method" but their need to be some modifications done to the original rootboot img file. Shouldnt be hard for devs

Think for the Xoom it would be from a windows command prompt:
adb shell cat /dev/block/platform/sdhci-tegra.3/by-name/boot > c:\boot.img
I could be wrong but try it and see.

It's actually a Permission issue.
/dev/block/platform/sdhci-tegra.3/by-name/boot: Permission denied

So someone with root needs to run it. Anyone wanna help out? Im not getting mine till tomorrow but by then I suppose you would have yours exchanged

That's actually the catch-22... can't get root because we don't have the right boot.img file. I think it's going to boil down to Motorola releasing a stock one.
If anyone is up for IRC chat - hop onto Freenode and room #Xoom

I can try if someone tells me what needs to be done. I tried copying it over to another folder in root explorer but no luck.

Update: Ran through the fastboot oem unlock in hopes that it would resolve the Permission Denied. It did not.

You'll end up with a (soft)brick

No luck
I also booted into fast boot, tried and still got no permission sometimes and no such directory some times... If some one will walk me through getting the img file I will gladly do so

how can I remove the softbrick, I saw this AFTER I tried to root and now I cannot even turn it off, just sitting on the Motorola Dual Core Technology screen.

ok I also now need to the stock boot.img from a wifi xoom. Can anyone help? I can flash it if someone can provide it please, if not I guess I will go exchange my xoom in the morning.

anyone started to root the device?

has anyone started to root this device?

Whaha really Genius!
But rooting can't be far away now..... Because I don't think the Durex is sold out in the super market. I actually think they have a special offer...

It's precisely because of the lack of root access that I've held of unlocking my bootloader; I don't see any point of having to erase all my data and setting up my device when there's no pay-off in the form of root and custom ROMs

Yeah well you never know if SE change their minds and cancel the unlocking website
Better get your gift before Santa takes it back
I will try to convince Marc from MIUI to think about the Arc...

I don't think SE will change it's mind, but the longer you wait, the more adjustments you make on your device (well at least I do..). So that's why I unlocked the bootloader as soon as I had my Arc. Even though I had allready played with it. But what the h*ll, now I had to play a bit longer with it. I don't see the problem

They wont change their mind but the downside of unlocking is that you cannot update using SEUS
Hopefully SE will change that if you use stock firmware but have the bootloader unlocked

I don't see where that's a problem : if you unlock your bootloader, it's because you want to flash custom roms, isn't it ?
Who care about stock update when we get better functionnalities and often faster updates with all the leaks with custom roms ?

I need somebody to carry out the following steps on their bootloader unlocked device
1. Enable USB Debugging
2. Run adb and enter the following commands (line-by-line)
Code:
adb shell
su
What is the response?

Phone app requesting superuser

This just started today. Anyone else having the Phone app request superuser?

I just had "reset notify" request superuser, and I'm at work so I haven't had a chance to figure out what it exactly is yet.

At least I'm not going crazy. I managed to catch the command and it's trying to chmod 666 a modem file. I'm going to turn on full logging in su to see exactly what file.

If the stock phone app is being granted root, might there be a possible root exploit somewhere depending on the command?

I doubt it. I would be more interested to see if it's checking for root to change or disable something.
It only does it about once every other day though.

It happens to me too. Running BoneStock 1a. I have it set to deny and not prompt me and haven't noticed any difference whatsoever.
The phone app asking for root randomly seems like a dirty hack someone made and those tend to be sloppy. What if you could symlink the chmod target, or adjust the path variable to have it execute something else?
I am now pretty interested to see the command it's trying to run, lets turn on logging and see if it happens.

I have gotten it a few times, not since v1.0f but nothing I changed would make it stop, not sure what the hell it wants permission for and wy it's asking for it, but I also denied it.

I've also been getting it several times in the last few days.

I get it on my stock rom just after unlocking bootloader and installing supersu on launch day. Like others I just denied it. Haven't seen any side effects yet since then.

HTC Service Accessory or something similar to that requests root every few days on mine. Is that what you guys are asking about? Haven't had the phone app request access yet.

No... the Phone app. I haven't had any other system app request root access on any of my devices, it completely undermines the security platform.
If the Phone app is being granted root on a stock phone, that means that app is whitelisted for root access somehow. And wasn't there a recent Android vulnerability that allows you to alter the code of a signed APK without affecting the signature?

This is the command it is trying to run: chmod 666 /sys/devices/platform/mdm2_modem/msr_info
The mdm2_modem is public rx only, but would it be possible to change the app's PATH variable maybe and have it execute a different chmod since I can't tell if it is using the full file path to execute it.

Well my little newb investigation turned up nothing.
The Phone app is run as user "radio" uid 1001 which, unlike root, does have a PATH set to outside /system. Write access to /data/local/ would almost certainly give root but I'm sure that's probably known already.
Android bug 8219321 would have given root to original versions of The One running 4.1, but the Verizon version runs 4.2.2.
Oh well, obviously couldn't have been that easy.

Wouldn't chmod 666 make it writeable? That would be a sneaky trick is they put that request in there to check for root and change something. I feel like root = free tethering to Verizon lol.
I would think that there is a root exploit available for the one, but there is no point in using it right now because system is protected and the phone resets whenever you try to change system.

Yeah it makes it world writable which could be relevant depending on how that file is used by other processes. I'm sure there are others who have been at this longer so I won't waste my time looking for a unicorn.
And I think people would still like root even if they lose it on restart.

I'm getting this issue on a stock Rogers HTC One with root. Has anybody been able to gather the SU logs?

As was posted, it's trying to make a modem file writable. Fixing permissions might make sense. It also probably means that this is no big deal.

Changing dpi and warranty

I'm tempted to change dpi to take advantage of 4k screen but wanted confirmation if doing so would void warranty. Also how do you change dpi and do you need to be rooted?
Thanks

Any modifacation voids your warrenty
And to edit your DPI you need to edit /system/build.prop and look for a line that says
"ro.sf.lcd_density=480"
(480 part may differ per user or device)
( i believe 4k dpi is 820)

Hi, how you can do that if there is no rooting for that device?

I dont have a Z5 but Sony Xperia devices typically get a working Recovery shortly after release
I have tried pushing superUser through ADB many times logged in as sudo or root and it has been fine.
You can look up guides on "how to install ADB" and how to push "superSu through Adb"
It may be that my Z2's bootloader is unlocked hence why im able to root it so easily but i havent the time to test the fact.

But with my Z2 2 things stopped, post processing and xreality which in my opinion both are a waste of time

You can change you DPI by running
adb shell wm density 400
and reset it by running
adb shell wm density reset
You don't have to root or unlock your bootloader to change screen density.

Yeah the stock launcher won't adapt to the DPI the way you'd think. You could try Nova with the 400 DPI.

what is the consensus what is the best dpi?
