Hello,
I have a curios problem with my Smasung Galaxy S2 9100 ( German Model without Branding and 4.1.2 Stock ROM!) 2 days ago I had to charge the battery... As this was finished I plugged the cable off and switched the phone off. Next morning I tried to start the phone but it hangs up on boot. The flashing Samsung Logo stay on screen and the phone becomes hot.
So after 2 days of playing around with factory reset, adb shell and clockworkmod ( Installed after the crash (jeboo_kernel_i9100_v1-2a) ) I find out that the problem must be a App or similar. When I wipe the /data Folder with CWM Menu the Phone start up normal and comes with the Welcome Assistent. But then all my personal data is lost -> Not good
( I have made a nandroid backup with cwm so I can restore the defective state again and again)
So now my question : How can I find out what is the root cause ? I need a bootlog or dmesg logfile to find which component hang up the system on boot. I want to find out why it happend and how I can prevent it next time.
How can I debug this issue ?
Thanks and Greetings for your help.
Carsten
You are right there is a problem with app or system data
one of those partitions in your backup are fail.
I suggest you to find out witch partition is it may be it is
system partition so you can save your apps and settings
I dont know about Joboo Kernel but Siyah kernel got
something like Advanced Restore. So you will be able
to restore just system partition or just data or whatever.
Or there is a different method to recover your files from
/data partition. Plug your phone to PC navigate to your
sdcard there is folder with your beckup find data.tar
or zip or whatever compression is that. Unpack all files
it will take a long time. And then you will see all folders
what you normally have in your data. Copy what you need

As of yesterday, my CM7.1 phone won't boot - it gets stuck at the "rotating arrow" blue Android for ever. It's a Samsung Galaxy S II GT-9100.
I have been running CM 7.1.0 for several happy months now, and haven't tried to install or upgrade my ROM. The last action I took before this happened is that I made a full system backup (using CWM 5.0.2.6).
That backup is present on the internal memory. I can boot into recovery, mount drives and access devices using adb shell. So I do have an opportunity to fix what's broken, if I can work out what it is.
Given that the last thing I did was a backup, I checked to see if any of the partitions were full, but none are. (None is more than 42% full according to df; although strangely, df does not show any partition mounted on /.) I tried making another backup, watching carefully - that worked fine. I tried restoring the first backup - no improvement.
I've also tried wiping everything Recovery allows me to that's non data-destructive - cache, Dalvik cache etc. It hasn't helped.
How do I work out what's wrong? Is there a boot log file anywhere which might give me a clue as to what is wrong? I've searched for "*.log" but can't find anything obvious.
I don't want to do a factory wipe if I can avoid it, because obviously that will lose all my data. If I do a factory wipe and restore just the data partition, does that put me pretty much back where I was? If so, how do I restore just the data partition? The Restore option in CWM Recovery seems to do full backups only, and only from a particular directory.
The original CM and Google Apps zips are still on the internal SD (same versions as are currently not working). Would it be worth trying to reinstall those, without wiping? Or would that be data-destructive?
Any other ideas?
Thanks!

SOLVED - remove 0-byte data/system/profiles.xml
I tried doing a full factory reset from Recovery. This got the phone booting again, but without any of my data . Fortunately, ClockWorkMod has a "partial backup restore" function. I restored the data partition... and the phone stopped booting again.
So this is progress. I now had some idea where the problem lay. I finally found it using a laborious 5-minutes-per-cycle manual bisection technique. Delete half the stuff on the data partition, reboot, if it still fails, delete more, reboot... once you get it to boot, restore the data partition, narrow it down further. Once you find a top-level directory, repeat the process inside it.
The result: the existence of a single 0-byte file stopped my phone from booting entirely. The file was: data/system/profiles.xml.
I have no idea what that file does (there are only a few references online), how a 0-byte version of it got created, or why having it existent but empty breaks things but if it's not present everything works fine. I have no idea if anyone else will ever see this problem, or if they will ever find this forum post. But still, here's my Wisdom of the Ancients (google the phrase for the relevant XKCD comic).
I bought a clone samsung s4 19500 from bangkok last month.I downloaded an uninstaller (uninstall manager) from play store.Maybe by mistake i uninstalled some system file((Android OS,some mediatek file etc) to decrease internet data usage and my phone showed error messages.I quickly reinstalled somee uninstalled system apps using the backup files made by the backup data stored by the uninstaller program.but the error messages stated to increase.i removed my battery and when i opened the s 4 again it only kept on showing the opening message of "SAMSUNG" with some sound).what to do.plz help:
I also did the system restore/factory reset option by using power+vol up key but it did't help.i cleared user data also.What to do now?
THERE ARE THE FOLLOWING PROBLEMS
1.its a clone and i cannot go into the download mode.
2. my s4 cannot be rooted or unrooted and its just in a bootloop.
3.I did not have any recovery software (backup file in my phone).
4.help me otherwise I would be in big trouble.plz,plz just once.help me.
IS THERE ANY WAY I CAN INSTALL A NEW ROM FROM SD CARD WITHOUT ROOTING OR CAN I ROOT MY PHONE IN THIS CONDITION.I CAN ONLY GO TO RECOVERY MODE IN WHICH THERE ARE FOLLOWING OPTIONS.
1.reboot system now.
2.apply update from ADB
3.apply update from sdcard
4.wipe data/factory reset.

There are multiple problems you made above. First off is purchasing a clone device..there isn't any support for those phones on here so its hard to get an answer to anything. Besides that you didn't backup or do anything to ensure that you can have a way to restore if you screw something up. You deleted system files which has nothing to do with Factory Resetting. In order to revive your phone you must reinstall the system partition of the phone with either a stock ROM or custom ROM.. but since your phone is a clone you probably wont find any on here. Look around online and you will be lucky to find one. Other than that you have a cheap paperweight
Ask the seller
Talk to whoever you bought it from online, or if you didn't buy it online, search for one the same being sold from china.
I think the fake samsungs all started with MTK the 4 numbers depending on what crappy model you got.
Talk to someone that sells the fake ones and ask for a factory rom, you should be able to install it from standard recovery
mode as long as its signed.
Good luck, you'll need it by the sounds of things
Now u have only one way left that go to that place from which u got this phone.... Maybe they will reinstall the stock rom your device.... Or Ask in other shop nearby Can they reinstall the stock of this device

Take a backup of one device, copy it to the other device via USB, and then flash that.
Hit thanks if I helped.

Hi,
I'm new around, hope this is the right forum...
I have a galaxy s1 (i1900) which I flashed with a new ROM (2.3.6) in the past and then installed 4.2.2 from a zip, and it worked fine for a few months.
Having the same ROM file I used before, I tried to get it back to 2.3.6, as the 4.2.2 didn't work quite well, causing some problems when trying to make phone calls / receive calls.
After flashing the 2.3.6 again, the phone kept rebooting itself. Having read a few different guides online I tried all options - wipe data, wipe cache, wipe dalvik cache... then did some dramatic things like formatting /system, /cache /sdcard... I know it's not a very smart things to do when you don't know what you're doing, but I guess I felt I have nothing to lose at this point...
I also tried to reinstall 4.2.2 again and it only rebooted to the recovery mode whenever turning it on.
When mounting to USB I see no files in the device at all, only a folder called 'clockworkmod' with file called '.recovery_version' inside, and 2 empty folders named 'external_sd' and 'LOST.DIR'. It also shows it has 13.2GB free out of 13.2GB, which is weird, because the os doesn't occupy any of the capacity.
How do I save this poor device?
Many thanks in advance for your kind help!

My galaxy S2 (gt-i9100) was running cm13 for about half a year. Some days ago I let google play update my apps. The result is a bootloop.
I've used the voice recorder to record a lot of notes I need to remember. Is there any way to get those files out from the phones internal storage?
The CWM recovery installed lacks the option to wipe cache / dalvik, which I would hope could get the device out of the bootloop.
When booted into recovery, I've tried adb, but the device is unauthorized.
I think usb debuging was disabled, however, I'm not sure about that.
The ideas I have to solve this are:
1) flash some other recovery that will give an option to wipe cache/dalvik and be able to boot cm13
2) flash some other recovery that will make adb able to pull the files while in recovery mode
3) flash some recovery that is able to copy files from internal storage to sd card
4) factory reset, and hope the files don't get deleted (this is the very last resort)
The thing is that it seems like I'll need to do all installations from SD card via the current CWM recovery. Does anyone know of a suitabel download / howto that can help me get my files off the phone?
If reason for boot loop is Xplore file explorer latest update , uninstall it with developer advices:
http://www.lonelycatgames.com/wiki/xplore/crash_on_cm
I did factory reset twice because of app.
Thank you, Kepsilla. Unless that is an app that is installed with cm13 or gapps, I don't have it installed. But your link gave me hope:
If you have custom recovery on your device (such as TWRP), enter recovery mode, open file manager and delete folder /data/app/com.lonelycatgames.Xplore-1

That means that if I can install TWRP recovery from CWM recovery, I should be able to access the filesystem. That should open up to two possible solutions:
a) Copy my files from internal storage to SD
b) Delete / modify some files to take all apps I've installed from play store will not start automatically.
Does anyone know of a TWRP that would give any of these possibilities and install on a i9100 using CWM?
(I can't really experiment iwht this - I feel the risk of loosing the files is too high. I have to know I'm going the right direction when I do something.)
Solution was very simple: By holding volume down pressed during boot, the device boots into safe mode - no apps started. Then I could just uninstall the apps that were set to autostart. Reboot and problem was solved.
I came across this way to enter safe mode when googling a error message that started to pop up frequently on my S5 mini. S2 with cm13 appears to have the same way to enter safe mode as S5 mini with factory rom.
so i was snooping around my phones priv-apps folder looking at all the code just cuz im trying to learn more about all of this and it all of a sudden restarted after attempting to open a file called test mode. ( I know, very stupid of me). any ways ive tried things to fix like wipe the dalvik cache etc etc no luck. Ive know created a new twrp recovery image and im wondering can i restore it in a way where i dont load one of the partitions that is causing the soft brick?? also im on a rooted stock image and have xposed installed as well as i had made a twrp recovery file inside the GUI of twrp in the app it self. Can i flash that? IE flash the file with out the boot partition selected???
PLEASE HELP
What's the problem at all? An annoying weird black square with writings on it?
Is it rooted?
Then simply open /efs/factoryapp/factorymode in a text editor (EFS Explorer, Root Explorer, etc.) and change "ON" to "OFF" (without quotes). Then reboot.
The problem is caused by EFS partition, so you may restore only this part of your backup.
