Boot loop after rooting with PhilZ touch 5

This was more than a month ago.

I am novice to rooting and flashing custom ROMs. However I was able to follow the process mentioned in http://xdaforums.com/galaxy-s2/deve...lz-cwm6-stock-kernel-cwm6-root-exfat-t1877270 and successfully rooted S2 using PhilZ touch 5. Previous to this the phone had the OEM stock FW.

I then began uninstalling Samsung bloatwares one-by-one. I vaguely remember that the uninstalling process was very slow. After clicking the uninstall button of an app, it would be unresponsive for few seconds before it shows a process bar of uninstallation but I sometimes impatiently clicked another time before the progress bar appeared. Whenever I clicked uninstall twice, after the successful uninstallation there used be another pop up error notifying that the app doesn't exist. It was in one of this instance that the phone went into boot loop.

Following are failed attempts to fix:

1. Rebooting

2. Wipe Cache partition

3. Re-installing the PhilZ-cwm6-XWLSZ-OJC-5.15.9-signed.zip again.

My requirement:

1. Any way to fix this without using extra Hardware and without losing my personal data that is residing in internal storage that are not backed up online. (SMS, phone contacts, app data). It's OK if I can backup all of it and restore it after factory reset or reflashing ROM.

2. I know that factory resetting or flashing a OEM or custom ROM would delete all the app data.

3. Even if the process requires extreme diligence, I am willing to do it.

So you can reboot into recovery? If yes go into the recovery, then mount the sdcard0(internal sd card) as usb storage, then with usb data cord connect to a pc, then copy your files to the pc. You need the correct drivers installed on the pc before this

[Galaxy S II Q&A, Help & Troubleshooting] :
Hopefully you can access this from your computer -

The sms/mms database is located in /data/data/com.android.providers.telephony/databases/.

The offline videos and whatsapp files should be in seperate folders in /data, but you would need to look for them(I don't use them).

What you are asking will be difficult to do, mainly because every app could have a different place it puts settings/files, and not always just in one location. You could try googling "where do whatsapp(or whatever) store files/settings" and see if that helps......
[Galaxy S II Q&A, Help & Troubleshooting] akprashant:
Few more clarifications

I am able to reboot to download mode or recovery mode and then access both internal and external sdcard from PC. How do I create an backup image of the storage that encompasses all the partitions, which I can use after doing factory reset/ re-flashing? I feel the advantage of creating a backup as image instead of copying individual files to PC, is that creating an image stores the original file access rights intact. This would help in easing the process of restoring the user data files if I happen to know the path for each app's user data. Correct me?

In the PhilZ Touch 5 UI, what do these options mean or the consequence of choosing each of these options:

Wipe Data/Factory Reset

-Wipe Data/Factory Reset

-Clean to install a New ROM

Wipe Cache Partition (Why there are 3 No options when one would have done the job?)

-No

-No

-Yes - Wipe Cache

-No

Backup and Restore

-Backup

-Restore

-Delete

-Custom Backup and Restore

-Free Unused Backup Data

-Misc Nandroid Settings

-Backup to Internal sdcard

-Restore from Internal sdcard

-Delete from Internal sdcard

Is it that the PhilZ backup option should have been used before the the bootloop issue happened?

I just need to restore the user data not the complete Firmware/ROM/OS, So are the backup options provided in PhilZ good enough now in this sense? Which partitions are required to be backed up? Would the PhilZ backup same as image backup?

What else are the possible ways?

Thanks.

The best way of backing up app data like you describe is to install Titanium Backup app, or something similar. I don't know of any recoveries that will do that

Hi,

Thanks for the tip, but my bootloop seems quite different : my phone is stuck at the first screen "Samsung GALAXY S II GT-I9100". No boot animation, no sound, no nothing.

Tried to flash many ROM with ODIN but after a few seconds, process hangs : progress bar gets stuck and nothing happens. I can access CWM, flash a kernel with ODIN, but unable to flash any ROM. And within CWM, it seems too fast : only a couple of second to install a ROM... and no boot.

Tried USB jig but no go... Is my phone bricked ? :-/

help plz?

It all started when i tried to root my Samsung Galaxy S2.

I tought it was to confusing to use the long way of rooting so i used to supercurio auto root kernel. I followed the instructions and everything went fine, but when the phone rebooted (like it said it would) it got frozen at the Yellow Triangle boot screen. After this i tried to flash many different kernels without luck, i tried to flash firmware roms aswell but that didn't work either.

The battery seems to be depleted and there is no way for me to open the Download Mode.

Im really new to the android world and i would be the happiest man in the world if i could possibly get the right answers.

P.s! When my phone actually had battery i couldn't open the Recovery Mode :(

Hi,

i have some problems with my phone...

i didn't use my phone from the 1st time i got it i waited for a cover..i started using it after 3 days.

i rooted the phone and installed games and applications on it..along with movies and few songs...

everything were fine..on day 4 when i connected the phone on the charger the phone switch it self off after that all the problems started..

when switching on the phone it only shows the samsung galaxy s2 logo on and off,when i remove the battery and re-insert at times it will boot correctly.

but even if it boot you can notice the lag while showing the S animation after that you will have lag in the menu also..

i tried inserting the original kernel still same thing..the phone also gets hot when in charger and also when the loop boot starts..

from what i read some ppl are saying that a faulty board can cause that?

i did tried a wipe user data..still same

i also tried the latest ROM..no luck

i was wondering if you can have some info.

What happened to my galaxy S2 storage

Got the phone 4 weeks ago and used it for a week. Never been rooted.

I was on a call, the phone just shut itself [battery was almost full] and never recovered from it.....then found this forum and tried the rooting but no luck.

Called Optus, the phone was sent to Samsung as it was under WARRANTY. After two week got the phone back yesterday.

I was surprised to see my

total storage capacity

has dropped down to 11.5GB instead of 15GB i guess when i first had the phone. :confused::confused::confused::confused::confused::confused::confused:

Funny things happening

HOME + POWER + VOLUME UP and then VOLUME UP+HOME when the Samsung logo appered

A white box with Android out of the box and under that

--Copying media files....

Successfully copied media files.

#Manual mode#

--updating applications....

after a while

A triangular Exclamation mark with Android appeared
[Galaxy S II Q&A, Help & Troubleshooting] cmoravin:
OK...........did this

1. Turn the POWER OFF, pull the battery out and put it back again. This step must be followed.

2. Simultaneously press the Volume Up, Home and Power button

3. When the Samsung Galaxy SII GT-I9100 appears, release the Power button

4. A Boot Menu will then show, Use the volume up/down to choose wipe/reset to factory and home to select to reboot

the device did reboot and went to the second screen which has this "S" symbol

after say 5 min or so, i got the create account screen but the touch screen was slow to respond. Skipped the create account but after a min or so, it rebooted again and back to the first logo screen [ ]

Clockworkmod cant restore backuped data

hi OP, i also had gone into bootloop problem 2 days ago, i din get to find this thread tht time bcoz i din know tht it was actually called "bootloop" haha..anyway i had solve the problem myself and now phone is working find

but i was just wondering tht why during boot loop when i enterd recovery mode with CWM and tried to restore ,CWM say no files found ,

does this mean all the backup using cwm was deleted? so means there is no use backing up with CWM since if something happen it cant find the file

? ( bcoz now my phone after tht incident currently on kg2 without cwm(havent lash it) , i am thinking should i flash back CWM into it to do a backup)

[Galaxy S II Q&A, Help & Troubleshooting] Foggie:
Has anyone experienced anything similar to this?

I did a full reset of the phone, wiped cache, dalvik etc. Then flashed the phone to a stock KG6 firmware. and this all booted in and I set the phone up fine.

Then I flashed Litening Pro v5.0 which uses the setmod kernel I believe. Anyone this all flashed fine and booted up no issues. Then I setup my company exchange email account and the problem happens:

I setup the email account fine and then it tells me that it needs to turn on certain security features. So I setup a password to unlock the phone and then it says it needs to reboot the phone to apply encryption. So the phone reboots, gets past the Yellow Triangle and then gets past the second samsung logo screen. At this point it asks for my password so I enter it and then I get an error saying "Failed to encrypt data" and my phone stays at this screen only allowing emergency calls to be made.

I tried rebooting numerous times and eventually thought I'd try flashing the CF-KG6 kernel. This flashed fine and then after rebooting, it encrypted my data and all was well.

But if I try changing the kernel to say Nimpo 2.0.2 or 2.0.4, the phone on reboot just appears to lock at the yellow triangle screen and goes no further. I've left it for 30 mins and it just sits there.

I tried putting setmod kernels and Hellcat etc and they get past the yellow triangle and just seems to stay on the second samsung logo screen.

So I thought I'd try another complete wipe again and this time flashed LitePro v4.2 (uses the Ninpo Kernel 2.0.2). This flashed fine, booted up and let me into setup the device again, no issues. I setup a few apps, wireless and did bit of browsing etc, setup a pop email and this all was fine...

Then came time to setup my exchange email again and as before it all installed fine, setup what to sync etc and then it asked to reboot the device to encrypt data again....guess what...the same thing happened on reboot, I get past both logo screens, enter my password and then get "Failed to Encrypt Data" and phone sticks there. If I flash another kernel, either stock or one of the CF kernels, on reboot the phone encrypts the data and works fine.

Anyone have any ideas why these other kernels (ninpo, setmod etc) fail to encrypt data and even if applied after data is encrypted they just freeze at the 1st or 2nd boot logo?

Bit long winded post, but trying to not miss anything out.

Thanks

I believe that custom ROMs don't work with the encryption at present.

Would need to see a logcat etc, but I suspect they look for root access when enabling encryption, etc, or perhaps that stock kernel is in use...
