[Data2SD-EXT] *Automated* Dalvik Left Internal

Yup, another data2sd script
Dalvik-cache is left internal on mtdblock5 (formerly /data)
/cache linked to mtdblock5 (so you can use cMTD to shrink the original cache partition down to 2MB leaving 302MB to be shared by cache and dalvik-cache)
I've only tested with a clean install but in theory it should be automated to add to your existing ROM in the /system/etc/init.d/ scripts (presuming your ROM is already setup to run scripts from that directory on boot). Also, this does NOT play well with existing apps2sd solutions or data2sd solutions. If you are already running one of those you would probably want to use Titanium Backup then do a clean install.
Here it is pre-installed into the 12/4 nightly of The Ultimate Droid for CDMA Desire. If don't know how to implement it manually in your existing ROM or you are having problems getting it implemented you can always use this instead.
Edit: Updated script with a bug-fix for the dalvik-cache on reboots

Thank you for sharing!

I have only to insert the file in the init.d folder and flash rom?
Can i try with any rom?

tnx bro ... for the script
testing it ...

If i'm on auraxTsense do i have to delete stuff2sd file and paste yours ? After that just reboot and i'll have data2ext? I have 512 ext2 and the rest is fat32

Yes, you would need to remove any apps2sd scripts. This is only been tested by me using two fat32 partitions (not an ext2 partition) and I'm not sure how nice this will play if you already used an apps2sd solution.

Can someone explain to me how to add this to a preexisting rom? I currently am running firerat's cmtd.. do I need to disable that, or are they compatible?
Additionally, if needed, how do I reverse it?

Am currently running LeeDrOid 2.2f, so what if I want to run this script? I've done a clockwork backup with ROM manager and Titanium backups on my SD card so what steps do I now need to take?

Hi I'm interested too to know what i need to do for apply your script please ?
Regards.

Well the way it should theoretically work is partitioning your card and copying the file to /system/etc/init.d . When I did that I had to force the script to start from terminal emulator and after about 10 minutes the phone showed a lot more space, but everything was FCing, so I rebooted, got stuck in a boot loop, pulled battery after 15 min or so and it booted fine, although all of my settings/apps/widgets were gone. I also saw no performance increase in quadrant, running a class 6 16gb card. It might need to be integrated or something for it to work.

I think on existing rom with a2sd+ it should work like this:
Make a backup on your apps and settings (MyBackup, Titanium, etc)
Boot in recovery.
Make a nandroid backup.
Via adb or QtAdb (easier) delete a2sd script from init.d
Copy script from first post to init.d.
Optional, but could be essential, do it if other way don't work: wipe sd-ext, dalvik-cache.
Reboot.
The first boot will take some minutes until loop is created and data is being moved.
Restore MyBackup or Titanium backup if you done wipes.
If FC's occur try to solve them with RomManager.

You should put the script when in recovery.
Then reboot and it should do the work.

?? From ADB? I essentially did the same thing from terminal emulator.. I got the extra space, etc. Just no performance boost.

No, what you did was NOT essentially the same. you were doing it from within the OS. doing it from recovery the system is not booted and files are not being modified as your trying to move them.
I haven't tried using the script with another rom, but i was scoring over 2100 in quadrant using Navalynt's ultimate droid rom he posted with the script integrated.
I'm using a class 6 sd card.

In that case I'd suggest trying what you're suggesting before recommending it.
Edit: Sorry for the attitude, I know you were trying to help. I ended up deciding against it because I don't want the stress on my card doubt I'd notice any difference.

Hi navalynt,
Great script and very well written/commented. Switched to this script this morning, but like a previous poster, now apps won't install from market - starts to download then just stops. Thought it might have something to do with the market cache section at the end, so I removed it but no dice - still can't install apps.
Any ideas?
Jay.

Thanks for your great work !
I removed app2sd from init.d and copied 30data2sd to there.
I changed busybox to new one.
All process looks fine work on my MIUI 0.12.3. ;D
I'm using EXT4 partition, so quad score is 2000+- but I'm fully satisfied.
Thanks !

Apparently you don't have enough space in cache.
Reboot in recovery.
Restore the original script in init.d.
Wipe cache partition.
Reboot.

Hi bg_man,
Good suggestion, unfortunately doesn't work. Rebooted into recovery and cleared cache but still no go. In Quick system info it shows system cache as "Total:148MB, Free:106MB", so don't think it's the cache.
Jay.
UPDATE: Not sure what the problem was but I decided to start fresh (after a titanium backup) and wiped everything and then ran this script - working awesome (including installing from market now).
UPDATE2: scrap that - half way through the titanium backup restore everything start fc'ing. Now titanium backup won't start. Will give it another go tonight.

need explicit CM9/10 instructions for MK802-not working

Hi all,
Yes, I'm a newb here at xda, but not to the hacking scene. As my interests are in custom Firmware development/modification I am having to post here in General because of the 10 post limit for the Development forum portion. I hope that I may get a response here, but worried that as with most "newbie chat" type forums, they seem to get ignored.
Regardless, I have been trying to install the CM9 and CM10 to my MK802 PC thumbstick without any luck. The end result is either a bootloop with no video or a blank screen with no video output altogether.
I have been using instructions from here, but there seems to be a simple step that I am missing.
All requirements for Superuser, busybox, and smanager have been fulfilled, I am able to install CWM to do my factory resets and flashing, but I am not successful in the flashing. I'm not sure if I need to resize my system partitions, but that is something I've a feeling may affect the install. I've not seen any statements on the requirement, only that if the system partition is less than 350MB or so, to avoid flashing the gapps file, which I've followed.
I've attempted this on the FW710B, and the NEW03 image from the Rikomagic website as well.
If anyone has any ideas or can point me in the right direction to an already customized image I can flash with Livesuit, I'd appreciate it.
Thanks again,
T3ch42

optimal swap and / partition sizes??
Well, a little bit of an update. I took the plunge and repartitioned my internal SD memory. I chose 512MB for the system, and 64MB for the swap. That may have been not enough for the swap, but this was a new test.
This particular iteration was successful. I got the CyanogenMod boot screen and everything this time. The boot took a little while, hopefully just the initial boot.
It seems that this would be a pretty big step to take, but I really can't say that I saw mention of resizing the internal memory as being required.
If anyone has suggestions as to the optimal swap and system sizes, I would appreciate it.
Thanks

I believe that I used the partition tool through the recovery app that you install, but I'm beginning to wonder. CT says that you cannot resize it. I have installed the Uberoid image a few times, and that may have resized it for me in all actuality. I did notice that when I had a SD card in the machine, that the SD card was resized instead of the internal memory which threw a kink in the works. After CM9 was installed, I wasn't able to use the internal memory.
Still doing some tests though.
May have more info in a little bit.

What steps did you take to get CWM on the stick. I tried several all not giving me a screen on reboot.

Install the Uberoid img through live suit and format.
After it boots, check your internal storage. It should say about 1.69GB
install the recovery, and boot to it.
Do a factory reset in recovery as usual, and then install your cm9 or cm10 images(the zips).
Install the gapps and compatability zips and reboot.
That should be it.
I think that's the steps I took that were successful.
If I tried to partition it myself, I found that the internal sd would not be recognized, even after trying the format memory zip that is used to fix th ad card.
Hope that helps.

I may have not looked closely enough.
You're having trouble with the cwm install?
For that, I just installed su, updated that to the newest version, click on the i and let it check the installed version.
Install busybox and the script installer. Use the cwm 4.0.4, I believe it is, and install the recovery image to the mk802.
The recovery.img needs to be in the main memory to run the script. Once you've run both of the scripts as root by clicking the little button in the script installer, then the mk802 should boot into recovery.
If this is what you meant, then hope this clears it up.

Booting from external SD [CM]

UPDATE: This can't be used with CM10 Alpha 4 (or later) as it is due to the new partitioning system.
____
I made this thing time ago and I thought to share.
What it does is to boot a stock ROM from the external SD card. It's nothing special, I simply changed few things here and there. I did it because I needed a stock ROM for a couple of minutes and this was the faster way to get it.
I'm using CM and I made this with that in mind, so, don't use while using a stock ROM. It won't mess your current setup, but it won't work.
You need to change kernel to boot the stock ROM (reboot recovery > flash zip. Simple and fast). That's because, as you probably now, kernels made for stock ROMs are not compatible with CM.
Prepare you SD card
You need first to repartition your external SD like this:
Code:
1° partition (mmcblk1p1): FAT - it will be the usual external SD
2° partition (mmcblk1p2): ext4 - /system (make it around 300MB big, 254MB will be more or less the space used)
3° partition (mmcblk1p3): ext4 - /data
I can't help you with this, I did it with adb and parted (the command is available in CWM). Look for instructions on the web, it's full of guides out there. Your external SD card is /dev/block/mmcblk1 (mmcblk0 is the internal one).
If you'll use the zip linked to flash the ROM, the two partitions (mmcblk1p2 and mmcblk1p3) will be automatically converted, unless they are already two ext4/ext3/ext2 partitions.
It shouldn't matter which kernel you are currently using and it should be safe flashing it, the only important thing is to have three partitions. If mmcblk1p2 or mmcblk1p3 are not detected, the installation will be aborted (it means that your SD card is not partitioned). Nothing else will be touched.
If you don't want to use the zip, mount mmbclk1p2 and copy the ROM there.
/dbdata will be the usual one (it's not used in CM. This will also makes Samsung apps a lot faster when using a slow SD card), same for /cache.
The flashable ROM is a stock XXLE4 + su/Superuser.apk.
How to use the additional ROM
To use the ROM on your SD, flash kernel-stock-SD.zip (see below) from recovery.
To go back to the real ROM you have to flash its kernel. Here below you can find CM10 Alpha 2 kernel, flashable from recovery. If you have doubts, reflash the entire ROM, it won't wipe your data.
I only mentioned CM10 because it's what I'm using, but this thing should work with CM9 too.
Things to know
I built the kernel using the latest Samsung sources with inbuilt ext4 support (and ext3/ext2 compatibility). Nothing else was changes, so I think there's no need to publish the sources, they are available here.
I attached the tools I use to unpack/repack boot images (they are a modified version of skin1980's tools):
Code:
./unpack.pl boot.img
./repack.sh [gz|lzma|bzip2|xz]
To see the changes I made, compare "out/android" with the stock XXLE4 ramdisk and the other two directories with CM10 boot.img ramdisk.
I changed recovery.fstab accordingly, but I can't tell you if flashing stuff from CWM while using the additional ROM will work as expected. You should read the updater-script to know it for sure.
I can only tell you that dhiru's builds will be flashed into the real /system partition and not your SD card.
Backups should work too, but I didn't try.
Of course, performances depends on your SD card. Mine is not that good I think, I took it from an old phone and I really don't know anything about it. The ROM is still usable, but apps that intensely use databases are slow (not Samsung apps, those will use /dbdata). Maybe disabling journaling will help (search for more info).
The Galaxy SL screen will last more than usual because I intentionally added a delay (3 seconds, SD cards are detected after a while) and of course because of the slower load.
Please, use this if you have some experience.
Note: dual booting two ROMs with a single kernel is possible, but only if they use the same kernel image. See this and this.

Wow ! thats dualboot for i9003 ! sweet gud to see development back in action

Good work.
The class of an SD card can be misleading. It is only a measure of the sequential Write access and that doesn't tell the whole story. Class 10 cards are great for cameras and applications that write or read sequential data, such as saving a picture and transferring a file. They are not so good for random access which is what the Android OS does when operating. In fact the random access speed for class 10 cards is lower than class 4 or 6 cards. From what I have seen, the sweet spot for smartphones is class 6.

Awesome. Only if we could achieve dual boot without flashing kernel everytime. But anyways awesome guide. Thanks.
Reminded me of dual booting of maemo and android on my brother's n900.

Dual Booting means you can have two OS's (here firmware) on the phone at the same time. You can choose on which you want to go. This, besides being awesomely cool, is really helpful in many scenarios.

But its not exactly a dual booting. On galaxy s2 dual booting uses a single kernel but in our case.we are still using two different kernels which has to flash saperately.
Really we should create a kernel which can be used for cm9/10 & for stock GB rom. Then real fun will begin

^But this can be useful when you have to go for a long trip and want to record videos which only our stock rom is capable of doing good. Thanks to the developer.
Also, if anyone can, please tell me what is the possibility we can create a dualboot kernel like siyah kernel?

I didn't say dual boot
Creating a single kernel for ICS/JB and GB is not possible, or at least not an easy thing.
CyanogenMod is using newer graphic drivers not compatible with GB. I tried to use my CM10 kernel with GB, just to see what could happen. Well, it works, but with no hardware rendering as expected. It doesn't mean "it's laggy", it's painfully slow. And if we'll have the 3.0 kernel working, I guess this will be even more difficult.
The only option I think is kexecing an additional kernel, but kexec is hard to implement.
However I dual booted CM10 and CM9 (SD) with a single kernel (there are traces of this in my unpack/repack tools), I simply added an additional "cpio.gz" inside the boot.img. There's an additional boot reason that we never use, so we can use it to choose the corrent "cpio.gz" by parsing /proc/cmdline. The only problem is that you need to boot the ROM first and the reboot, because to get the other boot reason you have to run this:
Code:
reboot arm11_fota #or arm9_fota
(if you are using a stock ROM and try to reboot with the command above, you'll see weird stuff, but nothing should happen to your phone. I did it once.).
Maybe there's something else possible, but dual booting never interested me. As I said, I did it because I needed it.
You can do a lot of things, I even stored a ROM in a subdirectory in /data and use it from there (=> fast).

I don't know how exactly dual booting with this kernel works. I actually don't know how usually dual booting is implemented in Android.
I just looked at it. It allows you dualbooting only two ICS+ ROMs (so no GB), it automatically creates an hidden partition, automatically stores the ROM there, provides additional tools in CWM and other nice things.
I guess is something possible, but don't expect it from me. As I said, I'm not interested in dual booting and this thing requires time and knowledge.

Ya a Universal kernel will do the trick.If later then we can achieve dual boot then the people who were holding back from CM9 or CM10 can flash that for features and a stock rom for stability and camera.

As long as the kernel is the same, yes.
If you want, here you can find the unpacked boot.img I (probably) used to dual boot CM10 and CM9 (SD).
There's no zImage in there, use the one you prefer, CM10 and CM9 are using the same kernel.
EDIT:
I almost forgot. "out/ramdisk/2ndROM" is for the ROM stored in your SD card, so you have to adjust the mount points there (already done in the one linked). "out/ramdisk/android" should be the "stock" ramdisk.
recovery will work only for the primary ROM in this case, maybe with some scripting you can make it works for both the ROMs, but I won't do it (if it's something possible).
The tools I posted will automatically take care of the additional ramdisk.

I don't know what happened to the links, probably I deleted the files by mistake on dev-host. Sadly I no longer have them and I currently don't have the time to make them again.
Anyway, I suggest you to follow other guides in order to replace only the corrupted memory instead (we have two different memories). This one for example, but there are other guides probably.

Thanks for your answer, problem is that my "device" memory is corrupted (as in read only).
I did the SD / USB storage swap but still have the problem that I cannot run/remove/install. So I need a ROM that loads completely from the external SD card and also uses it for data/storage...
I can flash a rom/kernel without problems, but changing version makes it only worse because the data does not get erased (background/applications/settings.... stays the same everytime, even after a wipe from the recovery).
If it helps I would love to pay/donate money to you as a thanks for your help and effort because the phone itself is working fine (except the corrupted memory of course) and would like to use it again

The guide I linked is fine then.
It explains how to repartition your SD card and the script Dipu K attached to his post is to use the newly created partition inside your external SD for /data. It's not to swap internal and external SD.
As I said, we have two memories, /data is in one, /system, kernel and other things are in the other memory. The corrupted one must be the one which holds /data.
Try to do as explained in the guide, if the problem persists, I'll see what I can do to help.

I followed the guide and got the Device memory replaced (data partition). Problem is now it is stuck in at boot because the partition is empty.... and when I copy the files from the corrupted data partition it boots fine but get message that I must wipe my data or the system will be unstable (which is correct because I get then flooded with unexpected errors which make it unusable). But formatting data partition gives stuck @ samsung boot logo??
So I need to get the "factory" data files from somewhere... I am running stock KPE ROM with BAM kernel (for init.d support).
Is it possible to extract the data partition from the stock rom?!

The content of /data is generated, there's nothing like what you asking for.
Maybe the problem is that the script posted in the guide copies the content of the old /data partition to the new partition inside the SD card. Wiping data shouldn't work because the path to the SD card is not specified.
Try the script attached. I zipped it to be able to upload it here, but it's not flashable. Since you've been able to follow the guide I assume you know how to use adb.
Wipe the content of the data partition you created inside you SD card (/dev/block/mmcblk1p2). You could reformat it with make_ext4fs, use a computer and so on. What's important is that it's ext4 formatted.
While in recovery, run:
Code:
adb shell mount /system
adb shell mkdir -p /system/etc/init.d/
adb push [I]PATH_TO[/I]/remount_data /system/etc/init.d/
adb shell chmod 777 /system/etc/init.d/remount_data
I'm sorry, but I currently don't have much free time to help more than this. With no logs or access to the device it's really hard for me to know what's the problem.

will be that you have a fast MicroSD card. Several have been tried and there is no real conclution as to what is the best in regards
to manufacturer or class (a class 6 card can have better random write speeds than a class 10 card), I use a Sandisk 64GB UHS-I
class 10 card and so does several others with good results.
The way this works is that you change the ramdisk so that it mounts /data to the second partition of your micro sd. Your internal
storage (the old /data partition) will be mounted as /data2.
Requirements
1. Unlocked and Rooted
2. You MUST repartition your Micro SD. The .zip you flash will mount /data to mmcblk1p2, which basically says "mount /data to the
second partition in the external SD." also, the ramdisk expects that partition to be ext4, so essentially:
Make sure you have an external SD with at least two partitions and that the second partition is formatted to ext4. I use fat32 on the first partition
because it's recognized by most devices.You will also need to make both partitions "primary" partitions. I personally use Gparted to repartition
my stuff, but feel free to use whatever you like. Even if you're on windows you can still use gparted by using virtualbox, or you can use a tool
called MiniTool Partition Wizard, I haven't tried it myself but it is reported to be good.
3. Research your Micro SD, find out if it has good random write speeds. There is no use in this mod if you card is slower than your internal
memory.
4. Although it's not a requirement it is a recommendation to have gone through the Nvflash procedure. It has saved alot of people from bricks
and is just great to have.
5. Verify that the .zip is compatible with your ROM, if it is not listed feel free to ask for a version for your preferred ROM.
Disclaimer
I take no responsibility for whatever happens to your device using this MOD, it is flashing a kernel so take precautions!
Installation
1. Boot to recovery, flash your preferred ROM
2. Reboot to initial setup (Don't run through)
3. Reboot to recovery, flash the matching Data2SD.zip
4. Disable journaling (Optional on all ROMs except CleanROM)
5. Reboot
When it reboots you will get a blue progress bar and it will be just as you flashed a new rom, you'll get the device setup screen.With my
MicroSD I get about twice the Random Write speed with this mod; Internal=0.20mb/s External=0.40mb/s . We will have a look at doubling
these figures further down (I currently have Random write speed average of 0.8mb/s).
Reverting
Flash a ROM

Modded Recovery
Enough with the screenshots, I think people know what it's all about by now!
TWRP 2.3.1.0 Data2SD Edition
Modded by flumpster, thanks a million!
Attached is a version of the latest TWRP recovery, the only mod done is changing where
it mounts /data so it backs up the correct partitions!
Backup to External will backup to your first partition (fat32 maybe) and backup to internal will
backup to your ext4/2 partition.It is recommended to back up to external which is the fat partition.
If you backup to internal which is now the ext partition and something goes wrong with that partition
you wont have access to your backup.
Instructions:
You must remove the old twrp settings from your prime for this to work correctly. Delete any
TWRP folders that are in sdcard, data2/media and removable/sdcard. If you have backups there
already that you want to keep leave the backups folder in the TWRP directories and then just
delete the files that are in the root of the TWRP folder to get rid of the settings left behind.
If you are on a windows pc just extract the zip somewhere and run the bat file and then follow the
onscreen instructions. It will flash it for you. If not, navigatate to the fastboot folder, find the .blob
and flash the usual way with fastboot.
I have tested it myself but would love some feedback on this as I am currently the only one testing.

Disabling journaling!
This is a mod that flumpster tested and found to work fine. I have tested it to and it is fast as a shark. It is somewhat
controvertial though, someone thinks disabling journaling on the ext4 file system could cause crashes. Also if you are
plagued with random reboots it can cause data loss. I've been running it for a couple of days without issues and getting fantastic results.
Here is a description on how to do it if you want to try:
To Disable Journaling in EXT4
Go into TWRP and then open a command prompt on your computer where adb is.
Type adb shell and enter it then type the following commands one at a time.
umount /data
umount /sdcard
e2fsck -f /dev/block/mmcblk1p2
tune2fs -O ^has_journal -c 1 -i 1d -m 0 /dev/block/mmcblk1p2
e2fsck -f /dev/block/mmcblk1p2
Watch out for the fourth line, after tune2fs - that is a capital O not a zero. The one further along the line is a zero.
To check if it has worked type the follwing after them
tune2fs -l /dev/block/mmcblk1p2 | grep features
If you don't see has_journal in the output all is good.

And the size of the ext4 partition should be?

I was planning on taking a stab at porting this project to the TF700 this weekend. Thanks for your work! Going to test ASAP.

That is up to you really, the ext4 partition will be your new "internal storage" so if you if you need to store alot there like big games etc. you'll need more. If like me you have little use for internal storage you increase the size of first partition. I have 49gb fat 32 as my first partition and 11gb ext4 as my second.
I transfer movies etc. from a windows machine to the fat32 partition.
Good question though, I should have mentioned it in the OP.

The mysterious CheckROM that you've mentioned twice is just CleanROM, right?

Yes, of course. Thank you for pointing that out, I've used CheckROM on another device so it got mixed up. OP updated.

Actually the ROM does this during install. However on 2.0 it was causing issues with the latest TWRP so I temporarliy took it out.
It ended up being a twrp issue. IM going to put it back in for version 2.1 (with will be 10.4.4.18 based) and revert to the old version of twrp. The newer 2.3.x builds dont seem as reliable at this time.
But good write up!

Also worth to mention that this mod makes it a little bit harder to do nandroids. But in TWRP you have a option to backup sd-ext, that will actually be a backup of your data partition. So to restore data you just restore sd-ext. All other partitions will backup and restore normally.
Edit: No longer applicable, sd-ext backup no longer supported. Modded TWRP recovery in post #2

Some feel more comfortable doing it! I feel like it's "bringing a knife to a gunfight"! False safety.

Since the 12/10 update to .18 that I installed just yesterday my performance skyrocketed. I don't experience any lag anymore, no hickups, much faster loading etc. I suddenly don't feel like this tablet was a waste of money anymore
It's all stock and normal.
So if you don't have this update yet, try it out before trying anything like this.

Would there be any way of getting this working on a rooted stock FW?
I saved root before updating to JB so I'm going to stay unlocked for as long as I have warranty.

Gospel singers from the General section? Now that's a first for me! I'm glad you're happy with your tablets,
now try downloading CleanROM 2.1 while multi-tasking on your device, still happy? I bet you want to unlock
before the download is finished!
New version for CleanROM 2.1 coming up, sorry for the delay. Been getting some sleep and my Inet connection
is about as stable as Uranium!
New version has symlinked /data2 partition so your internal storage will now be found in /sdcardi. Just for ease
of use.

what gapps package did you use, because a package i found on the internet did not work.
I really wanna breathe new life in this phone

Thanks for this awesome thread.
One thing I never understood in those scripts, should I format my sdcard first? In recovery? In a pc (using for example mini tool partiton wizard)?
What partition scheme do you recomend?
So far I have a 4Gb SD-Card but I may buy a 8Gb Class 10 one.

Just have one partition(sd-ext4) which will be your internal memory.
Just make sure you have formatted sd card and make partition.
Install the rom and flash the script on top of it (try int2ext).
It will increase if you follow the OP.

Tried before with ext3 and ext4 partition and in recovery it says installation aborted.

no you dont need to do anything beside make a backup of your files if you already dont have a sd ext just place the file and enjoy..... but if you dont have sd ext just get a sd card of class 6 or above boot into recovery go to advanced and partition sd card my recomended size is 2 gb... thats it... kill the thanks button if i helped

Regardless of which ROM or recovery i'm on, my device reboots randomly after some times(even after a thorough clean flash). Tried almost all of the ROMs .....but nothing worked. Posted my problems in other appropriate threads too.....but didn't get any reply. Finally tried mini Cm9.......but still it has random reboots.........any help is appreciated :good::good::good:

ok random reboots i once had them too there are two reasons for this problem and there are two solutions so dont worry
1. problem with batery:
pull out the back case and clean the battery terminals with alcohol and do the same with terminals on phone. now without putting the battery in press the power button for 10sec after that put the battery back in and voila nomore reboots.
if not then continue
2. problem with kernal:
it can also be caused by a faulty kernal so i will recomend that you flash a custom kernal. and to be frank try one of arsalan kirmani kernals those are stable
hope i helped :good::good::good:

I've tried different kernels in the past...but none helped....can you suggest one specifically ?? I only have a 4 gb memory card....so creating 3 partitions is not a good idea. I mostly rely on ICS ROMs. So any suggestions ?

Try without memory card. In the past I had one Nokia with problems like you describe and it was the memory card.
I had 4gb Class 4 with Fat32 and EXT partition without problems. Now I just upgraded to 32Gb Class10 for 9eur because I mainly use my explorer as mp3 player.
Using this rom http://forum.xda-developers.com/showthread.php?t=1876466 (MIUI cm9 based) with int2ext like this thread suggests and it is ok

MIUI rom is good, it don't have any problem of random reboots.. it is hardware problem... or try 2.3.5 android roms once.. before that format sd card and make perfect partition then change to default recovery and wipe everything which are necessary then flash a rom.. it may or may not works but give a try..
