Introducing.... Superboot! :)

Superboot is a boot.img that when booted, will root your device the first time you boot (installing su and the superuser APK). No need to flash any partitions, no need to mess around with ADB, no messing with the contents of your data partition, no overwriting the shipped ROM on your device, just boot the boot image using the instructions below and you're done!

APPLY THIS AT YOUR OWN RISK!

Superboot r5 - DOWNLOAD - MD5: 510c4a0c5a62407550abc5e028c6fd82

How to use Superboot - Windows, Linux and OSX

- Download the Superboot zip file above and extract to a directory

- Put your device in bootloader mode - Turn off the phone then turn on with the 'volume up' and 'volume down' buttons both pressed to enter the bootloader (as pictured below)

- WINDOWS - double click 'superboot-windows.bat'

- MAC - Open a terminal window to the directory containing the files, and type 'chmod +x superboot-mac.sh' followed by './superboot-mac.sh'

- LINUX - Open a terminal window to the directory containing the files, and type 'chmod +x superboot-linux.sh' followed by './superboot-linux.sh'

Note: If you are using a retail device, you may need to unlock the bootloader first, using './fastboot-windows oem unlock' (or the appropriate version for your machine, included in this zip). Note that the OEM unlock sequence wipes your device, so consider doing an 'adb backup' beforehand if required!

Enjoy! :)

[Samsung Galaxy Nexus] treble4:
cheers paul for this now can you sort an unlock please so i can get my tmobile sim working in it anytime before my t would be great in the next say 30 mins would be smashin ;)
[Samsung Galaxy Nexus] paulobrien:
Done! ;)

P
[Samsung Galaxy Nexus] pan24:
so this is a temporary or permanent root because i didnt understood well the ''until such time as you reboot after running this process (it's a non permanent ADB root as it's a 'fastboot boot' and not a 'fastboot flash').''
[Samsung Galaxy Nexus] paulobrien:
Permanent root.

[Samsung Galaxy Nexus] ballubas:
great, can't wait to get mine!
[Samsung Galaxy Nexus] beekay201:
I'm sorry, i find this a bit confusing. Why do you make mention then to 'reboot', if people dont have to worry about it (as in my definition of permanent).

Does superboot allow for root under adb (until restart), and for normal os operation+root access, the latter not being affected by a reboot, is that it?
[Samsung Galaxy Nexus] Evostance:
I'm a little confused by the terminology used here too. This is a permanent root? Not one that must run after every reboot?
[Samsung Galaxy Nexus] el3ctrik:
This is what he means. Running "fastboot boot" allows you to access the root shell using adb, however after reboot you will not be able to do that again until you reboot with the same command, or flash his permenant adb root .img from his other thread.

Once you have done this method once, the su binary and Superuser.apk are on your device, and will be there permentantly, until such a time as you remove them or you reflash a stock image. This means your on-device root is permenant too.
[Samsung Galaxy Nexus] Evostance:
Worked flawlessly on my Mac. Cheers!
[Samsung Galaxy Nexus] John Markley:
I can't think of any reason why this method using the r2 files won't work equally well on the USA VZW version when (if) we finally get it -- true?
[Samsung Galaxy Nexus] Chirality:
The boot image used here is a modified version of the GSM Galaxy Nexus boot image, I don't think it'll boot on the LTE version.
[Samsung Galaxy Nexus] siedkins:
I've come from using a Desire and just got the Galaxy Nexus. I've just unlocked the bootloader and flashed superboot using fastboot.

What I don't quite understand is why you wouldn't just want to flash the unsecure boot image from the other thread ? Or why this method doesn't do the same. I understand that this method reboots the phone using the superboot image rather than flashing over the system boot image file. But why wouldn't you want to override the system boot image to get full access? I suppose this is just highlighting my lack of knowledge of what I was doing before as I used unrevocked to get root access and custom recovery all in one go.

Sorry for asking these questions but it seems like there are a few people wanting to know the same thing.

@Paul - Big ups and thanks for posting this easy to use version.
[Samsung Galaxy Nexus] paulobrien:
Because the insecure boot image is just that, an insecure boot image - it doesn't root your device with the superuser binary / APK.

P
[Samsung Galaxy Nexus] gaspodex:
Excellent ... um quick question before i pop out - are the o2 contract handsets sim locked and if so if there an unlock solution ? (paid or otherwise) - i tend to switch between 02/voda a lot so need to unlock
[Samsung Galaxy Nexus] paulobrien:
Unknown.

P
[Samsung Galaxy Nexus] Evostance:
I think you can just call O2 and ask for an unlock code. Don't quote on that though
[Samsung Galaxy Nexus] GuestK00431:
I must be stupid or something cause I can't seem to unlock my phone? :-( done everything. :-S
[Samsung Galaxy Nexus] Evostance:
You got it plugged in on the bootloader screen?

Just cd to wherever you extracted Pauls superboot too and type:

./fastboot-windows oem unlock

Assuming you are on Windows..if not just change it for your os

Linux = ./fastboot-linux oem unlock

OS X = ./fastboot-mac oem unlock
[Samsung Galaxy Nexus] GuestK00431:
Actually it didn't work... ;-/ its finding the phone so not a driver problem but typing in ./fastboot-windows oem unlock does nothing other than give me an error saying its not recognized as a internal or external command.
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] Ginther:
I can get a Skyrocket right now for $150. But I was wondering what you guys thought the odds were that the price would drop again before Christmas? :confused:

I remember when I bought my current Captivate I think I paid $150 for it, then within weeks, the price dropped to $99 or $49. Which really hurt because we bought three Captivates - that's a lot of difference when you multiply it three times! :(

So do you guys think the Skyrocket price will drop any further in the near future? Or is it likely to go back UP to the $250 it was originally priced at on release date? :eek:

Just trying to make the best purchasing deci$ion$. :D
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] Kadin:
Well I'd say take advantage now and hope any further price drop happens within your first 30 days. Personally I don't see it dropping anytime soon, but that's just me.
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] john94si:
i got mine this week for .01 cent.. sorry

[Android Software/Hacking General [Developers Only]] pednekar.mohan:
I have a lot of widgets and lot of them are fullscreen widgets.

They need a lot of space and a lot of homescreens and switching between that many screes is a hell lot tedious.

I would suggest some developer to try making a launcher with following feature.

Icons for widgets. Click the 1x1 icon to see the full widget.

Others may put their ideas too...
[Android Software/Hacking General [Developers Only]] tmlhodge:
I suggest you make it.

"Galaxy Nexus Help" from Google:

http://www.google.com/support/ics/nexus/bin/answer.py?hl=en-GB&answer=1650160&topic=1650156

"Connect to keyboards, mice and other devices

You can connect a keyboard, mouse or even a joystick or other input device to your phone via USB or Bluetooth and use it just as you would with a PC.

....

You can connect joysticks, game pads and other input devices to your phone. If they work without special drivers or adapters on your PC, they will probably work with your phone."
[Samsung Galaxy Nexus] Balthazar B:
The OP is not looking for an input device. He's looking for unprocessed digital audio out via the MHL interface. There seem to be several MHL cables out there (mostly HDMI interfaces), but so far as I know nobody has tried to connect to an outboard DAC via USB. It will largely depend on whether the circuitry and firmware in the phone enable digital audio out via USB.
[Samsung Galaxy Nexus] danba:
I don’t know what is a (USB) input device, because USB is a bi-directional bus: a USB DAC sends/receives USB commands to/from the PC or smartphone like Nokia N8.

The key sentence of the "Galaxy Nexus Help" from Google is:

“If they (USB devices like USB DAC) work without special drivers or adapters on your PC, they will probably work with your phone."

Does ICS have USB audio driver?

Probably yes: “USB class for audio devices”.

http://developer.android.com/guide/topics/usb/host.html

http://developer.android.com/reference/android/hardware/usb/UsbConstants.html

Is the ICS’s USB audio driver compliant with standard USB DAC(s) which are compliant with the standard PC’s USB audio drivers??

Does the GN support the ICS’s USB audio driver??

That's why I am trying to reactivate the subject from time to time.

BTW, thanks for that. :)
[Samsung Galaxy Nexus] Chrono_Tata:
I would try to connect mine to my FiiO E7 but I don't seem to have any Mini USB to Micro USB cable lying around. ):
[Samsung Galaxy Nexus] Balthazar B:
Maybe you need something like this?
[Samsung Galaxy Nexus] Chrono_Tata:
Yeah if no one has tried this by the weekend I might go look around for one. Somewhat interested myself if this would work.
[Samsung Galaxy Nexus] edgeicator:
To get this to work, if it can even work in the first place, you need the modified kernel until Google fixes USB hosting on the Nexus. With USB Hosting enabled, you then need a micro-b USB to USB female OTG cable such as this: http://www.amazon.com/Micro-USB-Hos...2?s=electronics&ie=UTF8&qid=1322188402&sr=1-2
[Samsung Galaxy Nexus] allies:
Any update as to whether or not the E7 works when connected with a USB OTG cord?
[Samsung Galaxy Nexus] PhaedraCorruption:
I second the request for an update.
[Samsung Galaxy Nexus] Andrmgic:
If I could find my E7, I'd test it for you.. but it's currently MIA..

edit -

Found it, but it's battery is dead.. has to charge..

edit 2 - Audio doesn't output out of the E7.. is there some app I need to change the audio source? It does not appear that android changes over audio output on its own..

Probably something that has to be specifically implemented at the kernel level.. just the basic USB OTG doesn't seem to be enough.

[Xperia Play General] vemoxy:
Most threads about battery are quite outdated, so I decided to start a new one.

And so recently my battery is starting to get less muscular.. My Xperia Play is 4 and a half months old, and one hour of consistent 3G usage can drop the battery down from 65% to 24%. I'm not very sure whether that is the norm, but if it is, that's bad battery life, in my opinion.

The Android 'Battery Use' page shows that most of my battery is drained from Cell Standby and System Idle (30%).

My wireless and GPS is always off. Am on 2.3.4 rooted.

Also, Gameboid consumes battery like a beast (even more than 3G), but I guess that's due to the high processing power required for emulation..

Is there any way I can improve the battery life? :(
[Xperia Play General] BuckM:
Personally I found battery life to be terrible on 2.3.4 so I downgraded to R800i_4.0.A.2.368_World. I'm running 122M-1.5Ghz with scary and BFQ, on top of that I undervolted every frequency as much as I could using incredicontrol (Id give you the values but they vary by device). I always leave wifi, bluetooth, gps and data off when not using them, turned off automatic clock updates (there was a battery draining bug with this a while ago) and I run at 10% brightness with autobrightness off. With this set up I lose maybe 3-5% per night, so for around 6-8hrs in standby while I sleep. Ive got similar results on both cyanogen and stock. That being said I don't have a data plan so I do save a lot by not having data on, but a 40% drop in an hour isn't normal - Ive played an N64 emu which runs the processor full speed for that long and only experienced a 15-20% drop.
[Xperia Play General] brochador:
imho, the best battery life i've experienced is on 2.3.4.. when i'm on 2.3.3 i always lost 30-40% overnight (wifi, bluetooth, 3g, etc are turned off) stock rom, locked BL..
[Xperia Play General] Erikwithafro:
According to some folks, if you're charging your phone and let it stay plugged in for a while after it hits 100% that screws with the battery life.
[Xperia Play General] gbesta:
On 2.3.4 rooted with all the facebook, timescape and other bloat removed my battery is pretty good. Wifi is on 247 and it reverts to hspda when out. Data syncs hourly, and i have contacts, hotmail and gmail syncing.

The other day i was sitting at 57% after 1 day 3 hours, and that included a half hour go on fpse, might have been more.
[Xperia Play General] kupo5131:
Battery life seems good to me. I get 1 day usage then charge over night. I do use my phone quite a lot for this (Tapatalk), Phandroid app, Engadget app, Joystiq app and browser. Wifi and GPS is always on.

At a guess I'm using the phone for about 1 hour a time, about 7 times a day... So like 7 hours web use, phone calls and texts, syncing is set to every hour with FiX on.

When I was on 2.3.3 I'd be lucky to get 10 hours out of the battery but 2.3.4 is awesome.

Edit. Obviously I play games too. Forgot to mention that.
[Xperia Play General] vemoxy:
Actually I get similar idle battery drain rates as you, but personally I'm not very concerned with battery drain as long as it's not so much. I'm more troubled with battery life on consistent usage, which I feel the Xperia Play (or at least mine) sucks at.

When I play Gameboid, I get the same fast battery drop too - 40-50% in one hour.

Woah, 30-40% is insane! Glad that it's fixed for you.

Yep, I read that from a lot of places too. I admit I used to do that (and have since stopped doing that), but sometimes I can't help it if I forgot to charge at night before I sleep (and have to charge overnight to ensure I have battery the next day).

I envy your battery life :( One thing, if you remove Facebook, will your Facebook contacts picture sync go away too?

And did you remove the bloat stuff by deleting them from /system/app?

Sigh, I could never get such good battery life..
[Xperia Play General] BuckM:
All the more reason to undervolt, in standby undervolting doesn't have much of an effect on the phone since the processor is either in deep sleep or running at its lowest speed. Also using a governer like scary or smartass helps keep your device running at a lower frequency when possible. Like I said 2.3.4 was terrible for me, 10% drain overnight or more, but apparently YMMV with this. That being said 40-50% drain in an hour is crazy no matter what you're doing on the phone, like I said running N64oid for an hour drops me 15-20% keeping in mind this is at 1.5GHz with sound and the backlight constantly on. If all else fails you can always wipe everything and start fresh, carrying over the same settings while jumping around firmware can lead to some undesirable results. Anyway good luck and keep us posted
[Xperia Play General] gbesta:
The facebook sync option doesn't appear on my anymore, although it used to. To clean it up all i did was :

Purchase Titanium Bakup

Freeze the things I wanted to remove and test rebooting, only freezing a few more each time

Backed up every app

Slowly uninstalled each one with a reboot every couple of apps

Enjoyed my faster phone with better battery life

I use the gmail sync and life.contacts for contact pics
[Xperia Play General] dannejanne:
I get amazing battery life on 2.3.4.

In stand-by I lose 1% every 3'rd hours. It's very good in use too. Yesterday I had my day with heaviest use so far and texted like crazy the whole day and a lot of phone calls. Some surfing, gaming and updating of apps between that. Basically the phone was frequently used the whole day with short periods of stand-by in between. At night when I went to bed the battery was at 40%.

Earlier this week I used it minimally for 2 days. The battery dropped 10% for each of those days. But that was very minimal use.

So in short. I have not experiences better battery life on any other Android phone. What takes the most power is emulating. It can suck up like 20% in an hour depending on which emulator I use.
[Xperia Play General] dskid807:
I got my Play at the beginning of the week and with quite intensive use, without WiFi or 3g, I scraped an 8am to 6pmish day on the battery. Admittedly with a fair bit of gaming.

However, that was only waiting for my 2600mAh battery to arrive and now I'm using it, I would recommend it for the bulk. You don't notice it after half an hour or so and I have no issues with gaming on the go whereas I always thought it may die on the stock.
[Xperia Play General] vanleab:
mine drops 4 - 5% /hour..... much faster than b4.... dn no w is goin on w/ ma PLAY..... :(
[Xperia Play General] Growling Clover:
I found that since updating to 2.3.4 my battery drains quicker. Usually charge overnight and battery would be around 15% bedtime. (7am - 11pm approximately)

Now I'm finding that by 6pm I'm having to charge it and that's without gaming

[Xperia Play General] CZroe:
Three times in my first week and a half of ownership I awoke to find it completely dead despite fully charging it or nearly fully charging it before bed. I usually sleep with my phone next to my head so that I can ensure that the alarm will wake me up. That and the lack of a timer function really irk me about this phone. I really hate having to create and save an alarm when I know I only have 45 minutes or 2 hours to sleep (I work a grave shift and have inconsistent sleep schedules during the day). It adds insult to injury when something changes that lets me get another 5, 10, 20 minutes or so and I can't easily add it. On top of that, I have to go back and delete all the alarms I made throughout the day!
[Xperia Play General] AndroHero:
Thats crap. Infact you should leave your phone plugged in a good 30/45 mins after it says fully charged if you want a full charge :p
[Xperia Play General] markcyst:
Isn't it also beneficial to Li-ion's health to keep them at max charge whenever possible?...
[Xperia Play General] CZroe:
Not at true max but at what the battery controller considers max. True maximum will drastically decrease the total cycles just like true minimum only to gain longer cycles in the short-term. When you store a battery it's best to stop at 75-80% because it will lose stored energy slower and not spend nearly as much time near 100%, which is still a trade-off between long cycles and more cycles.
