To Upgrade Rom..Question

Please forgive the noobish question..this is my 1st android product and I am still learning...
I am currently using Task650's rom version 5 along with the current pershoot kernal....If I want to move to Version 6
1. do i only wipe the delvrik cache,then flash version 6?
2. do I need to reflash the kernal after flashing version 6
3. what is the easiest way to backup all my apps if i have to wipe everything and then put them back?
i am using a rooted 10.6 wifi only...just really trying to get the hang of if there is an order to flashing roms and kernals like if i install a new rom or even update if i have to reflash kernal and reset setcpu?..thanks in advance.

Please Anyone... I really wanna do this...

1. Most scripts wipe dalvik cache when install or upgrading a ROM. Check with rom author if your not sure. With V. 6 from V. 5 its not necessary.
2. Yes, V. 6 will flash stock kernel. Unless noted in original post from ROM creator, custom ROMs "generally" have stock kernel. Other forums this is not true. You will need to setup SetCPU again after flashing.
3. Titanium Backup, it's a very powerful tool for backing up data apps. Rule of thumb, DO NOT backup and restore system apps, you can put your device in a bootloop or other bad things like applications that force close all the time.

Just a FYI: no need to boot the rom first though. Flash ROM, directly flash Kernel and then boot up. Good luck!

I've seen it recommended to reboot between the ROM install and kernel install. Though I can't say that there is harm that I am aware of.

for #1, task650 said: "You only need to wipe dalvich and cache to upgrade from V5"
for #2, havent tried to flash the kernel yet but will give a shoot asap
Any advice how to do it is more welcomed
for #3, titanium backup ftw

corrupted nandroid

Hey guys i think there is something wrong with my phone because every time i do nandroid backup and then restore from it i always end up in a bootloop, no matter what rom or kernel i am on... it wasnt happening when i was on gingerbread roms like cm7, it started when i switched to ics rom (cm9) and since then every time i restore from nandroid, the phone ends up in a bootloop... can you guys please help me? If you dont see my sig - heres my specs: Galaxy S I9000 phone running on Slim 3.1 on Icy Glitch B6 kernel. The initial base ROM is KG3 2.3.3 Gingerbread - from there i went to cm7 then slim.
PS: yes ive tried completely wiping everything via Odin but still didnt fix the problem.

Are you restoring the backup using the same rom, cwm version that you used when you ran the backup?
eg if you took a backup of stock jvu, then upgraded to ics, you would need to flash stock jvu, then restore

that's right. if you backup in jvu, you can restore only in jvu roms. If you try to restore a JVU backup on another rom, it will bootloop

Well yesterday i nandroid backed up my phone on slim 3.1 then flashed CM9 nightly and didnt like it, so i went to cwm and restored from nandroid and ended up in a bootloop...
Edit: They're both ICS too though.

The only time I have been able to restore successfully is from CM7 to another version of CM7. So flash Slim again, and then restore the nandroid backup.

What the ....?
If you do a complete Android backup, you can restore a jvu rom after flashing jw4. You cannot restore a jvu rom if you flashed a cm or miui from, but always a gingerbread on gingerbread from. Always a ics after flashing a ics rom. I was on icssgs 4.2 and flashed cm9. Restored icssgs without problems. And the same with slim ics....

Really? Because this time I tried going from cm9 back to my slim 3.3 and it bootlooped. I had to wipe data and reflash the slim ROM :/

Dowgrading GB to previous kernels

Hi guys,
I accidentally installed GB kernel (2.6.32.9-ge281b6e) on my DEFY (not defy+), when I wanted to try the new CM9...
I really liked ICS but I don't like the fact that the camera is unusable and the battery is leaking really fast. (maybe because of the kernel)
Is there any way I can downgrade the GB Kernel?
Thanks.
Nikola

did u just flashed the small CM9 kernel?

I had cm7 and wanted to instal the cm9.
I went to a thread and downloaded the GB kernel installer (cm9) and installed it from recovery, than the CM9, rebooted and... no return?

Mhhh sounds good. Try to flash the cm9 file again?

Did you wipe cache and dalvik cache before and after the flash? If you haven't, this is the most probable reason for the bootloop. Wipe them now and reboot - you should be fine now. And yes, you can always downgrade kernel, as long as you don't flash a full sbf with higher CG39.smg version.

Sry guys i havent made myself clear enough ... The phone is working fine... But no camera and battery is leaking really fast. Im not stuck in the boot phase aka bootloop... The phone has GB kernel..how to downgrade the kernel?

Just flash CM7 kernel and then a CM7 ROM. Done.

[Q] How to go back to MIUI Pickachu Edition 2.xz from CM10 nightly (18-Nov)

Hi folks!
As the title suggests, I want out from JellyBean and back to MIUI Pickachu Edition 2.xz
I think the latest 2nd boot builds have the GB kernel since I see 4 Vsel levels, so should I flash the froyo kernel?
If so, what should be the order of flashing ROM -> Kernel or other way round?
Also, I have a nandroid backup of when I had MIUI. What steps do I have to follow to restore it, i.e, do I have to flash the ROM (and/or kernel since I was on froyo kernel when the backup was taken) to restore nandroid?
I read a lot about the fuss of latest nightlies changing /system and /data to ext4, but in my case they are ext3, so I guess I should be alright?
Reason for going back is LAG! the immense amount of time to open stuff. I tried loving it, but its just too slow to the point I feel like its running Windows 8 on Intel 8086.

Please post all questions in Q&A. Thread moved there.

Hi!
My friend was in same situation and he went ahead and tried to flash MIUI Pickachu edition, but his process got stuck and now his Defy won't boot.
Hes now flashing stock Froyo sbf.
Thats the reason why I need to know instructions to get back to MIUI without going through sbf flashing.
Any help gladly appreciated!

how do I install miui and cyanogenmod both on defy MB525

any help in installing miui on defy would be much appreciated.

You need to flash a Froyo SBF. For some reasons going back to 2.3 always ends in a cache error, flashing 2.6 kernel, nandroid, fullwhipe etc. doesnt work

R U on Froyo or GB? if Froyo try to flash fixed sbf I will attached if needed.

Just flashing froyo kernel was ok for the 2nd boot builds upto 9 nov builds.
From 9th nov builds the cm10 rom formats our defy to ext4 file system, so in order to downgrade we need to flash the sbf.

My friend, thats what I have said, in my OP,
I have checked using mount command from rooted shell and I can confirm that my /data and /system are STILL in ext3 even though some say that the latest nightlies change the fs while formatting.

Try restoring your backup, you may succeed, otherwise you need to start all over again, with the sbf. I find it better to start all over anyway, no matter, what rom we are talking about. Those installed over a freshly flashed sbf proved to be snappier and absolutely bugfree - at least for me.

Simply try to restore your backup. I tried many roms so far, aslo the newest by Quarx and Epsylon and i always worked for me to install a new rom/zip/ withour anything further. Never installed a sbf.

Was quite late in posting a reply but I did end up flashing Stock Defy 2.2.2 SEA sbf.
I did flash successfully MIUI (Pikachu edition) but it was a bit off, so took a backup and flashed sbf.
Have been on stock ever since (been kinda busy).

If you just flash the new nightly (and I'd reflash the gapps too) you don't need to wipe anything and you won't loose ant data

Ok cool. I have couple of questions if you don't mind.
What do I flash first? ROM or GAPPS?
I heared some nightlies have issues, is there somewhere I can look to find them?
Will I need to reflash Franco Kernel?
thanks
