Problem after TB restoring.

Hey guys,

I use Kyrillos for a long time now, and everything was fine, but I re-flashed it recently, and now as soon as I restore my data with Titanium Backup, it crashes a lot, I can't open my app list, and it seems that my SD card isn't scanned on boot anymore. Do you know why is there a problem ? Because all of my previous backups worked just fine after restoring.

Thanks.

6. I have too much lag!

- Make sure that you dont have more than 50 User Apps installed in your phone.

- Go in titanium and do a batch operation: Move all apps to internal memory

- If you have a linux-swap partition in your sdcard, delete it.

- Go in Settings/Sound and disable all Feedback sounds (leave the haptic feedback checked if you want )

Okay so I'm the noob that hasn't got a clue :D

I'd love to have Kyrillos ROM on my i5800 but I can't seem to get it to flash to that, I've got the basic idea though... I think, I was able to install the Incloud ROM but just one of the earlier releases (not the latest) and as you probably guessed by now I tried the Kyrillos ROM with no avail so I'm currently on the official Froyo release but would love to change... even more so as predictive text isn't working :/

Any help or point in the right direction would be greatly appreciated.

So if i want Fugumod 800Mhz v2.4.beta3 on 5.5 do i just replace the zimage given in the fugumod download with the zimage found in your .tar package and flash it again? Its because I want to overclock it.

[Galaxy 3 Q&A, Help & Troubleshooting] anant.0097:
okay so you know how to flash using odin ....... and you want to know how to apply the 5.6 update through CWM recovery.......

Assuming you've flashed the kyrillos rom v5.5 through odin one package method here's the step by step break up on how to apply the update:-

Download the version 5.6 and put the update.zip file in the root of your sdcard.

Reboot your phone into recovery - for this switch of your phone and press both the volume key, the power key and home button together.... once you see the i5800 screen leave only the power key (the volume keys and the home key are still pressed) till CWM recovery boot's up.

once the recovery boots scroll down using the volume keys to Flash update.zip package and press the home button..... wait till the process completes and then reboot..... and your done!

slow boots on 5.5

just flashed 5.5 from I5801DDJP2 following the steps mentioned in dev thread.

Some steps were ambiguous.

Go in download mode (Vol down + Home + Power), insert sdcard. And then Start in odin.

1. I had to deselect OPS in odin (http://xdaforums.com/showthread.php?t=873645)

2. As soon as phone started in dl mode (pressing the 3 buttons) , I let go of the button , and inserted sdcard and then clicked start in ODIN almost immediately.

I hope the above steps were correct by me.

I've noticed a few differences between stock and this.

1. My phone boot times are 5-6 mins. Is this normal Or is my flash borked?

Stock used to take half this time or less.

Currently I see the model number screen for about 2 mins, and then the green droid logo for 3-4 more mins.

After the first time, i could browse thru apps fine.

I'll soon insert sim and check all phone functionality one by one and confirm if anything is actually borked.

I'll post more updates soon.

Thanks in advance for helping a newb and his first post :)

UPDATE#1 - After partitioning and another wipe data and reboot and another reboot, boot time is now around 2 mins

few more questions

More updates:

1. i dont see much difference in perf betn stock and this tbf, tho quadrant score has increased from 330-340 to 370. I still hate my phone whenever it lags oh so much.

2. Does it make a difference if I flashed from DDJP2 or jpm/watever the others are? I mean doesnt the custom replace everything that the original firmware had left, baseband firmware, os , etc?

3. How do I flash the OC version on the default 5.5 non OC? Wanna try that and see if things are smoother. I Used some cpu app , which let me set clocks of only 83 or 667

4. Installed sygic from market. Maps are downloadable, but whenever I actually start sygic, it throws a popup pls enable gps ( when its not), and after enabling/hitting sygic , only a black screen. have to remove battery to get phone functional again.

I've seen some complaints like this on market reviews. Was wondering if anyone has sygic working properly with G3 and 5.5
[Galaxy 3 Q&A, Help & Troubleshooting] dhirend_6d:
Yes. The baseband version is replaced. You will see that the baseband version is 15800XXJPM. And it also replaces the kernel. And it changes the filetypes of certain partitions(/system, /data, /cache). To fix lag.

And for overclocking, you need to flash a new kernel which supports overclocking. That will make things smooth for you I suppose. Here s the link to the kernel : -

http://code.google.com/p/fugumod-i5800/downloads/list

Flash the kernel same way you flashed the ROM suing ODIN.

Quick question. For flashing the package, do i select the kernel image as "One Package" ?

Also, if I flash reiserfs supported kernel, will CWM recovery show format as reiserfs or do i have to manually partition the sd card externally

ThanQ very much sir and thanq for the fast reply
[Galaxy 3 Q&A, Help & Troubleshooting] dhirend_6d:
Image?? Yes, select one package and in "One Package", give the path of the kernel.tar which you download.

Through CWM recovery, you can create ext4 and linux-swap partition in your SD card. And if you flash reiserfs, jfs supported kernel, then it will allow you to convert the system partitions to reiserfs, jfs. Ofcourse you have to do it manually. Because chaging kernel does not change the partitions. It only provides support for those partitions. In Kyrillos' ROM, the partitions are already lagfixed and converted.(/system ext2, /data ext4, /cache ext2) It has nothing to do with SD card.
[Galaxy 3 Q&A, Help & Troubleshooting] V!KR@M:
yes u have to tick the one package option to flash kernel. Changing kernel doesnt wipe ur data.
