Is it possible to change the recovery of a kernel! I mean manually change the recovery version! I have a Xperia P and I am having problem mounting emmc on Philz recovery, so I wanted to change the recovery to CWM recovery 22.214.171.124 of my favorite kernel.
I have a verizon samsung galaxy s3. I'm planning to upgrade to the kitkat 4.4 but I was going to do a nandroid backup first. Using rom manager I am attempting to go into recovery mode but everytime I try I get this message:
System software not authorized by Verizon Wireless has been found on your phone. Please turn off your phone and go to the nearest Verizon Wireless store for support.
I disabled the knox sensor and then totally removed it and it's components. I don't know what else to try.
When I got my phone at the end of last year I rooted it using a Chain-Fire kernel - v 4.2, I think. After flashing, it worked perfectly, since when I have flashed the old bootloader to get my USB Jig working to remove the yellow triangle and flashed a patch again to allow the USB Jig to reset the binary counter.
I have very much wanted to install and get the new Sky Go application working.
What I had to do was flash the Stock kernel for my Stock Rom - I have never messed with my Rom - it is Gingerbread 2.3.4 in a CPW phone here in the UK.
Doing the flash and installing Voodoo OTA (to temporarily hide my root) has been enormously successful
Now then to my query....
The original Chain-Fire mod v 4.2 installed CWM.
After of course cancelling the "hide root" function to show my phone as rooted once more, I went to do a backup, using CWM but it refuses to work. It says my kernel needs v 5.0. Obviously the Stock Rom I flashed to get Sky Go working has thrown CWM some what.
I have downloaded Rom Manager from the Market but this seems not to work either - it starts to work (reboots) but then halts with the following messages: -
E : failed to verify whole-file signature
E : signature verification failed Installation aborted
What I would like is some way of installing a backup previously made before flashing the Stock kernal and also to make a fresh backup now.
Does system recovery "Wipe data/factory reset" resets custom kernel to stock?
I'm asking this because im noob, and I want to try JellyBlast for Galaxy GT-S5570I. It has two zip files to flash one is ROM, and one is custom kernel. If I do something wrong I'm afraid that I won't be able to restore nandroid backup.
I have rooted and installed Rom Manager on the Captivate; can I install a new kernel through clockworkmod recovery as a zip file as I am able to do on my Moto Droid 1? Any suggestions on kernels that will allow overclocking?
I've managed to create a TOUCH Recovery Carliv v2.2 based on CWM V 126.96.36.199 recovery for the Zen Ultrafone 701HD.....
Link for the TOUCH Recovery Carliv v2.2 based on CWM V 188.8.131.52 recovery for the Zen Ultrafone 701HD.....
Easiest method to have this recovery for a rooted phone is below.
1.Install mobile uncle tools from Play Store.
2. Place the recovery.img provided in root of SD card.( Rename the recovery file as simply RECOVERY.IMG)
3. open mobile uncle tools and flash the recovery.
The other ways may be followed from this link of Dextrorototrix
Full credit for this Recovery goes to Yuweng who created the auto tool CWM Magic Create [URL] found in this link [URL], and Carliv who created the recovery that made it so easy to port to new devices, Napster who shared his touch source with Carliv, and of course the original creator of CWM - Kouch. It took many hours of hard work to get us to where we are today.
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 currently have bekit 1ghz kernet installed, but I was interested in trying out some other kernels. Can I just install them via Rom Manager over the first kernel? Or is there some kind of uninstall process I should use first?
We know that the ROM is installed to the /system partition. Likewise the kernel ie boot.img is installed to the /boot partition of the device. I tried hard but could not find any reference to such a /boot partition(directory) in the root of the device. I would like know whether it is hidden or disguised as something else. The script that flashes the custom kernels has the following line
Code: package_extract_file("boot.img", "/dev/block/mmcblk0p9"); (What is the block code for system and other partitions?)
Is mmcblk0p9 the /boot partition? Moreover /dev/block has no reference to boot or mmcblk0p9. So where exactly is the kernel being extracted? The boot.img comes packaged as zImage + ramdisk, In other words where are zImage and ramdisk extracted to, in the root file system and in what form? Is the ramdisk responsible for the creation of the root files system(/dev, /proc, /data. /system, /sys, /sbin etc)?
Well I am working on beagleboard-xm project, where I am supposed to upgrade the current Android version to ICS. The thing is, I have to keep the current kernel , because it is customized for some applications that run on that board. It is not me that compiled that kernel...
Is it even possible to keep the "old" kernel and upgrade to ICS? Can it be done in any way? Or a new kernel with new patches has to be installed...?
I have a small query why cant i use the stock kernel with Cynanogenmod ?What is the difference between the two and how can I make a stock kernel compatible with Cynanogen mod when building one from source
unable to flash a kernel through fastboot it's showing the device is not rooted,but in flash tool it's showing the device is rooted,even all the applications are showing root is allowed but when i'm going to flash the kernel through fastboot its showing device is not rooted...
What sections of kernel code are changed for optimization of performance.
Like we can change 1) the minimum free memory that android need to keep free. 2) Rate of clearing cache 3)Advanced LMK- where we can kill more than one process at at time when memory scarcity occurs. 4) Reducing logging. 5) In framework we can change the oom_adj value of important processes. 6) Implement Zram for kernel. 7) change the minimum and maximum no of process for AMS.
I want to know all the changes that can be made into kernel or framework code to optimize performance. I also want to know how can we implement swapcache for android kernel. What changes do i need to make in the code.
