My Atrix with factory ROM is now in a boot loop. I have none of my pictures backed up. I tried clearing the cache partition as well as safe mode. I can get to the login, but I'm greeted with force close messages until the phone reboots. I can't get the phone to stay on long enough to connect the USB. Is a full data partition causing the boot loop?
Help :-(
Have you unlocked the bootloader and installed a recovery? If so, there are options there that might help. Try fix permissions under advanced first. If it still won't boot, you might have to wipe ddlata/factory reset. It shouldn't delete your pictures just settings and apps. Then clear cache and reboot.

If you don't have recovery, you could try to boot into fastboot. Use PC to do moto-fastboot -w.

Lastly, get an micro-sdhc and reader to put the pictures on. It should ask you if you want to start storing pictures on the new card when you fire up camera the first time after adding the card. Smaller ones are pretty cheap online these days. Then even if the phone dies, you can just pull the card out.

I did the data/factory reset, and you were right. All my pictures were still on the device. I guess I'm confused. What partition are the pictures stored in? I was assuming they were in the data partition. Thanks for your help.
I was confused about that initially too. I thought of the part where I put files as the data portion. However, that is technically something like the /mnt/sdcard or /mnt/sdcard-ext partition. The pictures usually end up by default in a folder in /mnt/sdcard/DCIM/. The data partition is /data. It holds application system data and settings. It's all a bit confusing.
I am posting here as there is not sub-forum for Xperia Pro.
I want to flash kernel using CWM already installed on my phone. Is it possible? If so, how do I go about it?
PS: I found a thread which is for Samsung phones here.
I don't think so
There is no way to flash a Kernel for SE phones faik

Can anyone tell me why kernel cannot be flashed via flash_image and the like. Is it because /boot partition is locked in Xperia phones? Or because the there is no proper flash_image made for Xperia phones?
That's something like ; doing a bypass surgery while you're awake
Something like that ^

I am not a complete nooby. flash_image can be used on (at least) Samsung phones, to flash kernels.
I have a nokia n900(linux kernel)...and i can flash kernels from the phone itself...dual boot maemo OS and android...restore the whole system image on the phone itself...but on neoV...it is not possible.
dont know about other android phones because neoV is my first android.
On PC you can update BIOS, on some motherboards you can do it from Windows, on others you can use some utility in BIOS setup program, on another motherboards you need true DOS and use BIOS flash program, same is with PC video cards, with PDAs...

Exactly what does flashing a kernel with flash_image have to do with recovery partition?

The phone's internal memory (not the SD card) is solid-state (flash) memory, AKA NAND. It can be partitioned much like a normal hard drive can be partitioned. The bootloader exists in its own partition. Recovery is another partition; radio, system, cache, etc are all partitions.
Here are the standard partitions on an Android phone:
/misc - not sure what this is for.
/boot - bootloader, kernel
/recovery - holds the recovery program (either clockworkmod or RA recovery for a rooted Evo)
/system - operating system goes here: Android, Sense, boot animation, Sprint crapware, busybox, etc
/cache - cached data from OS usage
/data - user applications, data, settings, etc.
The below partitions are not android-specific. They are tied to the hardware of the phone, but the kernel may have code allowing Android to interact with said hardware.
/radio - the phone's radio firmware, controls cellular, data, GPS, bluetooth.
/wimax - firmware for Sprint's flavor of 4G, WiMax.
During the rooting process, a critical piece of the process is disabling a security system built into the bootloader that protects these partitions from accidental (or intentional) modification. This is what's referred to as "unlocking NAND." The security system can be set to active or inactive. S-ON means the security is in place (NAND locked). S-OFF means the security is off (NAND unlocked). When S-OFF, you have the ability to modify all partitions. With S-ON, you only have write access to /cache and /data. Everything else is read-only.
When you flash a custom ROM, that ROM typically includes a kernel and an OS. That means the /boot and /system partitions will be modified at a minimum. Some ROMs require a clean install, so a format of the /data and /cache partitions is sometimes built into the .zip that you flash. This is essentially doing a factory reset. See next paragraph.
When you do a factory reset (AKA: wipe, hard reset, factory wipe, etc.), you are erasing the /data and /cache partitions. Note that a factory reset does NOT put your phone back to its factory state from an OS standpoint. If you've upgraded to froyo, you will stay on froyo, because the OS lives in /system, and that is not touched during a factory reset. So "factory data reset," as it says under Settings > SD & phone storage, causes confusion. It's not a factory reset. It's a factory DATA reset. Now you know the distinction.
The SD card can also be partitioned to include a section dedicated to storing user apps. To create the partition, your SD card needs to be formatted. Typically a user will copy all the contents in the SD card to a PC hard drive, wipe the card and partition it, and then copy everything back.

Then show us HOW to install kernel via recovery?
Dont talk about Samsung and HTC option to install kernel via recovery. I have HTC Desire my second phone and yes i know there is option install kernel via recover(also im tested ALL desire roms and kernel already).
SE xperia have just different partitions layout and we simply cant flash kernel via recovery.....BUT i dont want tell you its IMPOSSIBLE.
Be nice and show us how to do that
PS:im tottaly noob.
Boot holds kernel and initrd not the actual bootloader, that is what should be writable. Provided the actual bootloader is not damaged it should be possible, however because there is no recovery partition it is riskier, but s1tool can restore bootloader......
Hmm

I have S2(of course i have and xperia neo) and i dont flash with CWM i flash with odin or heimdall; CWM method is not sure.
In my opinion,and i'm NOT an expert, it easy to flash a kernel for xperia with flashtool or using fastboot from adb.
OK guys, you might have misread it. I am looking for a way to flash kernel not just using CWM (eventhough the title says so), but using any method without having to connect to a PC. One such possible method is to use flash_image in terminal, which does not work in my phone.
PS: The fact that I am not a noob doesn't make me a pro.
Dear xda friends,
has anyone find a solution to format / reset the prime without format the internal memory (32gb full of my photos,...)
it's frustrated to copy via the slow usb connection all the images again after a reset,..

I'm not sure but could wipe in bootloader work. Anyone can confirm.

A system reset returns the internal memory to its factory state.. that is the entire point of a rest. There is no way to perform an actual reset without erasing data stored internally.
If you have data that you need to keep, back it up before resetting the Prime.
Usr cwm wipe.

If you want to reset only data partition, you have to unlock and install twrp or cwm

So when I am preparing to rom my phone, I obviously have to wipe. Where can i store things on the phone so as not to get wiped and what do I need to wipe before roming and flashing boot?
When you're flashing a new ROM, it is recommended that you do the following things:
Factory Reset/Wipe Data
format /system
Wipe Dalvik Cache
If you would like to make sure you don't lose anything as a result of these wipes, you really should just back it up to your computer to be 100% sure it will be safe, but the phone's Internal Memory should stay intact between wipes. This is basically the phone's internal SD card (sort of).

So when I download a Rom I want to be flashed such as teamvenoms in this case, what directory should it be in? I think my issue has been I was drag and dropping them onto my media device (phone) in windows. But this foesnt explain losing my os when flashing a recovery.

I don't know anything about losing your OS when flashing a recovery, but that sounds like quite an issue that you should probably resolve before going forward with flashing any roms (a bad recovery could be a huge headache for you in the future).
In order to install the rom you just need to store it on your phone's internal memory, which is the media device that shows up when you plug it into windows. Then you can boot into recovery, select the option to install a custom zip (or something like that, not looking at it right now) and find the zip file that you put on your phone.
Came a little closer to the issue. With cwm i can see all my downloaded files including the Rom I'm looking for but in twrp literally all my directories are empty (or it shows them as such) and it says I have no os then flashing back to cwm it's all still there. ???

Formating system is an unnecessary step, almost all ROMs wipe system during the flash so its redundant to do so
Plus if the ROM has asserts to prevent flashing a incompatible ROM it would continue to flash anyway. And could result in a brick on certain devices
Slithered from my HTC One X+
My sister installed her work eMail which enabled Encryption (I believe only on the Data Partition).
She does not really care about having her work email, so we removed it.
But that still leaves everything Encryted.
After Googling Around it appears you need the Factory RUU to get the Phone Back to Stock.
But that is not availble yet.
Does anyone know a way to either Flash a ROM or Take the Encryption Off.
We tried both TWRP and CW Recovery and neither can do a Backup because they cannot Mount Data.
Any suggestions welcome.
I'm personally on a Sprint HTC One
Perform a factory reset or boot into recovery (I am not sure about the HTC One stock recovery but I did this with my Galaxy S3) and format the /DATA partition.
Use titanium backup to backup all system data and user apps + data to sdcard, copy backup folder off to a computer, factory reset, copy the backup from PC to sdcard, then restore.

This worked. CW Recovery Failed. But TWRP worked. It got a whole bunch of failures until the last step that it formatted data. Then I ran it again with no errors.
I was a little surprised formatting DATA now includes the internal SD drive, that really sucks.
Thanks
