General :: Using Locked Bootloaders To Load Unsigned Kernel
Oct 17, 2012
A long time ago, on a 386 far, far away, some people would regularly boot Linux from DOS/Win16/Win32/Win95/etc... using a utility called loadlin. Loadlin would basically grab the system from the short and curlies, and load a target kernel into RAM, and jump directly into, which would effectively be running the kernel in practically the same way as if LILO had loaded it.
Would it be possible to actually make a Linux kernel module which did the same thing? Modules can be loaded at bootup, so it could be configured on a rooted system to load this module, which would effectively jump to a new kernel, throwing the old one out of memory.
what phones are available now on Verizon that come closest to the Nexus experience? I've been installing alternate ROMs since a week after I got my G1, and I'd never consider a phone that couldn't be completely unlocked. Out where I live, though, Verizon is the only option for decent service. Add to that the fact that I'm grandfathered in with unlimited data, and I won't be switching carriers anytime soon.
I have a i897 (captivate) and was wondering, if i am on stock ROM, 2.3.5, do i also have GB boot loaders or will i have to install them. if it turns out i have to install them, looking for tar file for GB boot loaders so i can flash it with Odin.
This is a general question that should be in everyone's mind who might want to root a phone or tablet or any Android or other mobile OS device:
Is this root exploit or bootloader going to be spyware and collect any and all data of mine (login credentials, keylog my every character, account/bank numbers, identity information, use your evil imagination)?
So, I searched this forum for key words like "trust root" "secure root" "security" and found nothing related to this topic.
So, how am I to trust ANY of the root exploits or bootloaders created and posted to this forum for ANY device?
Have any of the developers developed an audit process using firewall rules to ensure that a posted root exploit or bootloader does not attempt to keylog, report captured information to some obscure IP address (thief/hacker's machine of course)?
Do any of these root exploits or bootloaders or custom unofficial builds of entire android (like Cyanogenmod and the 3rd party variants) get Security Audited?
How am I to believe that the whole lot of you making the root exploits and bootloaders are not a big community of identity thieves and financial fraudsters?
what's the difference being "Export Signed Application Package" and "Export Unsigned Application Package"? Under 'Signing for Public Release' in the dev guide it says you must:
1. Compile the application in release mode 2. Obtain a suitable private key 3. *Sign* the application with your private key
But then it continues:
"To prepare your application for release...To export an unsigned .apk from Eclipse, right-click the project in the Package Explorer and select Android Tools > Export Unsigned Application Package."
But below this under "Compiling and signing with Eclipse ADT" it says to "To create a signed .apk, right-click the project in the Package Explorer and select Android Tools > Export Signed Application Package...When you complete the Export Wizard, you'll have a signed .apk that's ready for distribution"
Do I need my app signed or unsigned for distribution on market place?
Interesting article, wonder if it gives the "owner" of the smart phone ownership at all? It is written for the i phone, but may open doors across the board. I would love to see someone take Motorola to town. New U.S. rules allow for unapproved i Phone apps - USA TODAY.com
I have a sony ericsson X10, it has a security pattern lock on the phone. However this has gone off in my pocket and now the phone is locked. I can not remember the google email address for the phone and now i can not access the phone. Orange customer service has told me to get in touch with google, in order to delete the old account [whatever that may be] but there is no number for google customer service.
Does anyone know if there will be any unsigned apps on the captivate for AT&T? App sideloading? Or is ATT gonna lock this one down like the Aria and Backflip?
Engadget preview said: "happy to see AT&T hasn't done much to the OS" "AT&T may have been accused of crippling its Android phones, but the Samsung Captivate -- one of the US versions of the Galaxy S -- is about to change all of that."
But they don't mention whether or not they've disabled app sideloading and unsigned apps.
Currently a team of developers is working on Android application and during the development process testers already have to test the current state and report issues.
So far I have simply installed the application by connecting the tester's device on my pc and hit run in the IDE. This way we waste a lot of time if an application has to be installed on multiple devices multiple times daily.
What I would like is to send the testing team the .apk file and let them install and run the application by themselves.
I am developing a game for Android in Windows Vista environment. I want to automate the exporting unsigned application operation in a batch file. So, I wouldn't have to Right click on the project, go to Android Tools and then select Export Unsigned Application Package... anytime I want to run my project.
I have vanilla linux kernel version 2.6.27. I want to apply android specific patches and convert it to android linux kernel 2.6.27. Where can a user find the patches to convert a normal vanilla kernel into android kernel?
1. I updated to stock 2.1 using the sprint update tool. 2. I followed the video tutorial to root the phone 3. then i used joey's page (http://www.joeyconway.com/sdx/custom/index.php) to install the his kernel (joeykrim-SDX-kernel v2.0.4 (includes root)).
I have done nothing else to the phone but this and removing a couple of bloatware apps (i checked the list of permitted deletions before i removed anything.) I have not installed a new recovery..at least i dont think that I did as part of one of the other operations I performed (as an aside, i am not really sure what the custom recovery is or what it is used for, so i didnt install it...i guess i need to read up more...)
So that is where I am..but i have a couple of questions.
1) i am now having issues with my wifi connection - the signal reception is very spotty in areas where i should have atleast 2 bars of reception, and the wifi often cuts out completely....Is there any know corellation between joey's kernel and this wifi issue? I have searched the forums and have found nothing that answers this.
2) Is there an easy way to get back to the stock kernel? I have read that i can get back to stock everything by using the sprint download center where I did my original 2.1 update. But is there a way to get back to just the stock kernel without wiping the phone?
I have been assigned the task to use an android tablet to run a single app in an enterprise setting. Ideally, when one switches on the tablet this app should be loaded perhaps during startup and the user need not step out of this app. The app logic itself is rather easy but I am wondering if it is at all possible to load a single app during load and not allowing the user to step out of it.
Is it possible to load a layout XML at runtime and load into activity?
In my app, I have various types of data like Person, Company, City, etc; The requirement is to dynamically load the layout, find views by tags (property names like Person.name, Person.address) and then fill in data. For example, if user has selected an object of type Company, we want to load a company.xml layout, inflate it and then associate various properties (company name, company slogan, city, address, revenue) to tagged views. One possibility I see here is - each view in the layout will be associated with property-name as tag and then appropriate data will be loaded in appropriate views.
What should be the best design you would recommend?
Any app that will allow reading AND replying to sms texts without first unlocking your phone? I mean a phone that is password/pin protected.
Ideally, I'd like a lock screen that allows access to all non-sensitive functionality: camera, sms, calls, maps. The list goes on. The only things that need to be password protected are settings, email (as this can be used to reset other passwords), browser (where you may have saved passwords/credit card details), play store (or anywhere you can make purchases).
Have tried a lot of replacement lock screens like GO locker & executive assistant,
I upgraded my Dad to a One X a few weeks ago. Today he tells me about some sim message and then he said he couldn't make calls anymore.
Sure enough the home screen says the PUK Code is locked. Att tries to tell me that i can happen due to a variety of things yet they can't explain what these variety of things are so I tell the cs person to send me to tech support.
In the mean time I pop the sim out, replace it and restart the phone. Looks like he's back in business.
So it seems that I along with many others who have the Motorola Droid Mini, Ultra and Maxx on Verizon have been receiving our much anticipated 4.4.2 upgrade. As of about and hour ago I ran it on my Droid Maxx which is totally stock and has never been rooted and is pretty much brand new. As I typically do after and upgrade I started playing around with all the new features that came with 4.4.2, one of the being the ability to unlock you phone handsfree by speaking a pin code to it I decided to give it a try. So I hit up my settings and removed my trusty pattern lock, set my self up with a nice eight digit pin (stupid mistake #1), made it complicated as in not 12345678 (stupid mistake #2), didn't write it down (stupid mistake #4) and the proceeded to forget it in the amount of time it took me to lock my screen. Now I was under the understanding that I could bypass the lock screen with my g-mail account password, but I cant seem to find where, and to make matters worse I have failed the pin code 8 out of the allotted 10 times before the phone wipes itself.
I hardly doubt that Android 4.4.2 lost the ability to use your gmail account as a bypass in this situation did they? I know a lot of times people think that it is due to the phone not actually being signed in, but I have both received application updates from the play store and emails from my gmail account indicating the device is signed in.
I was backing up files and now the sd card is permanently "write protected." I cant format and cant write to it but the data is still there. There is no lock switch on a micro SD card so that isnt it. Is there a way to get the card unlocked?
I was trying out the Pattern Lock feature on my HTC Incredible S and got locked out after too many incorrect attempts. I can't use my email address and password to verify my account as my data and wifi are switched off.
To get around this problem, I've transferred to my microSD card the XtraSec apk that will allow me to remotely switch on wifi and data. However, I'm not sure how to trigger the installation of the apk when I can't get past the lock screen .Can I use fastboot to access the file explorer app (ES file explorer) or apk installer app to get the apk to install?
I haven't rooted the phone and it's running the latest version of Android. I'm not sure if I have USB debugging enabled. I'd like to avoid doing a reset if possible coz I haven't backed up the things that aren't on the sd card.
