I have Samsung i897 Captivate (i9000) with SlimICS 4.1.1 Cyanogenmod installed.
Yesterday morning I've found, that my phone is repeatedly show me boot screen (video on boot with many blinking pieces/elements colors shown to me), but did not load an Android at all. I've tried to reboot the phone (with battery eject), but nothing changes: phone shows start-up animations repeatedly.
Last my action evening before was setting alarm (usual task that I've done for one year probably). Dont know what reason to reboot was, maybe no free space available, but dont sure. Before this problem with load I have no problems with phone at all.
I have Clockworkmod installed, but there's no options to boot an Android in safe mode or some similar options. I could get access to the internal phone memory, but not for system partitions. I've tried to wipe dalvik/cache, fix permissions, but no changes at boot.
So could you gents help me to get access to the filesystem: I have memo's & uncynchronised contacts & SMS, which I would like to save before do anything. I know how to reinstall the system (I have backup for it, but not for contacts & memo's).
Thanks.

The I9000 and the I897 are 2 different phones. I9000 is the international version of the Captivate, therefor, if you flashed the I9000 bootloaders on a I897 Captivate, you'll have distorted colors/screen.
What exactly was done to the phone before this happened?
Pardon, I have AT&T i897 Captivate phone. I did not flashed, nor updated phone, nothing similar, that could affect phone booting process. Just set an alarm (default, from Clocks), then go sleep. In morning found that my phone stuck in boot process - it show boot-up animation but don't load OS.

Have you tried re-flashing the ROM (Without factory reset)? Wipe cache and dalvik.

No, I'm no so clean understand reflashing process, so worry to lost my data (I know that my contacts lie here - /data/data/com.android.providers.contacts , but can't found where memo's saved). I could choose "Restore /system" from
"Backup & Resore -> Advanced" in CWM, you mean this?

Yes, did it, but no changes at boot at all (wait there >10 minutes).

Reflashing your ROM won't touch your data as long as you don't wipe/factory reset. It's what we call a dirty flash, you just wipe cache/dalvik and flash your ROM again with the Gapps.
Thank you for the way to resolve the problem. Spend some time to understand the process of reflashing. Now I collected all files (bootloader, ROM, essentials, gapps and so on of my actual setup) and ready to reflash it with Heimdall.
But still have a question: is there any possibilities to get access to filesystem (for maybe just copy all files from system partitions into Big Brother) before take action in my case?
Will I get access to my contacts & memo's after reflashing? As I understand, if I reflash phone, /data & /datadata partitions (as part of freshy ROM reinstall) will be touched too, then I lost as minumum link to the Wizard Memo (and I'm not sure that installing it from Google Play will restore access to my memo's).
As you could realise, I have no actual backup of my data, so asking maybe dumb questions (
Could I simple use Clockwork's mod option "Restore /system" & "Restore /data" (as I have it in almost fresh backup - 2 months ago)? Will it be analogue to reflashing? Or it revert /system and /data to the stage when it was make, with contacts, programs and so on with 2 months ago state, not current?

I guess i wasn't so clear. What I mean by reflashing is to simply get in recovery mode and reflashing RemICS and their Gapps. Not to start fresh with stock.
Sent from my SGH-I747 using xda app-developers app
You explained well, errors on my side Resolved this issue with copying all data from filesystem, then reflashing with fresh slimrom . For those who fall into same situation: you could get access to filesystem of your phone trough ADB tool, and just copy sensible data to another partition/SD/device. See QtADB program also, very friendly for that.
Tried Vanir_101213 (nuklearmistake), runs well, but FC when opening "settings/security" (as in version 101013, dont have this issue in 100713).
Does anybody know how to reset only system settings (no full wipe), cause I installed vanir_101013 as third ROM (MultiRom) once again and the fresh install doesnt FC systemsettings/security. But this is the only issue I have with my fully installed version of Vanir, so I would like to reset only systemsettings (delete wrong settings), may be the issue with "security" could be solved by resetting. Tried to delete data under Apps/Settings/Details, but after that all system settings are as the were before...
I just thought I should mention don't do it!
If you really need to keep your cache tidy, especially on Marshmallow, do it from Recovery. I have tried cleaning the cache from both CCleaner apk and ASC Mobile Security apk and they cause app optimization to malfunction and the device to freeze and then bootloop. I'm not sure if this is CM 13-based specifics but if it is its a bug that needs addressing. Cleaning the cache from one of these apps causes a bootloop, of which is correctable by:
Power phone OFF
Hold down VOLUME DOWN and press POWER
Select RECOVERY MODE by selecting it from the blue box using the VOLUME UP and VOLUME DOWN buttons and pressing POWER when you see RECOVERY MODE .
Follow the instructions for your custom recovery ( Philz, TWRP, CWM, etc. ) to clean the cache and dalvik cache partitions.
Reboot to system.
When done, you should see Optimizing app x of xxx and you should be able to resume use without losing your data. Immediately uninstall any automatic cache cleaners and resume normal operation. Don't repeat the same mistake.
I either do it manually, by deleting it in root explorer and rebooting or I use the SD Maid app. never ever an issue. and BTW, its not an issue with stock or aosp, using apps to clear cache. that sounds like a user issue or a cm issue.
New Verizon S6 Edge (sitting in the box for 1-2 years) and I used the OEM adaptive fast charger to bring it from zero to 100% and then waited 10-15 minutes.
I used the built-in OTA updater, not Samsung/Verizon's Software Upgrade Assistant, and went through 11 system updates over the course of 2-3 hours. Out of curiosity, would using the SUA have reduced the number of updates to apply? Edit: I am almost certain now SUA updates straight to the current build (based on their wording, link at bottom). Apparently if I wanted to go straight to current system build, I should have used SUA or a tool such as Odin to flash the stock firmware directly.
Here is a list of the software builds I went through:
G925VVRU3BOG5 - This was the build on my phone out of the box.
G925VVRU4BOG7
G925VVRU4BOG9
G925VVRU4BOK7
G925VVRU4CPC2 - This is the first official build of Marshmallow for this phone. After update success, I decided to wait a few minutes and then restart the phone.
G925VVRU4CPD2 - I received error 404 after automatic download failed. Manual download attempt OTA was successful.
G925VVRU4CPF4 - I received error 401 after answering no to the automatic download request because I was trying to prevent the error above. Manual download attempt OTA was successful.
G925VVRU4CPH1
G925VVRS4CPI2
G925VVRU4CPK2
G925VVRS4CPL3 - My battery charge ticked down from 41% to 40% just before I applied this update, 35% upon completion/success message.
G925VVRS4CQA3 - This is the last Marshmallow build available for this phone.
On Verizon's webpage it says to have at least 40% charge or 20% when hooked up to the charger. I am worried because I did not connect my phone back up to the charger for these last two updates. The last one really bothers me because it was 34% when applied and 29% upon completion/success message. Is there a way to verify everything was written correctly? Should I even be worried?
With exception of a few failed downloads, all updates -when applied- said successful first try.
I have the understanding that it is important to wipe (system) cache partition and wipe data/factory reset from the recovery menu after major system updates to avoid all sorts of potential problems. So, here are my questions:
Does wipe data/factory reset from the recovery menu also wipe (system) cache partition? If not, should I wipe cache partition before or after? I have found conflicting information on this. Edit: It is so confusing because when you search around there are tutorials only mentioning the reset, others saying to wipe cache before reset and vice versa! There are also people going as far as doing both of these before -and- after a system update! Edit 2: It appears that wipe data/factory reset formats /data, /cache and /sbfs partitions. So, wipe cache partition is redundant when performing a factory reset from the recovery menu.
Both of these videos demonstrate wipe cache partition followed by wipe data/factory reset. You will see /cache is unnecessarily formatted twice (picard facepalm).

https://youtu.be/NUsV75KFLzA?t=65
Note: there is no Google account to remove (Factory Reset Protection/FRP, Google Account Lock etc) as this is a new phone.
I am under the impression that I should clear all app cache, app data and maybe reset network settings before I attempt the recovery menu methods above. This is overkill/redundant, right? Edit: All this stuff appears to be stored in somewhere in /data (even an app's cache, within a subfolder of each app).
Aside from backup (in my case does not apply), is there anything I should do before (or after) recovery menu wipe(s)? I want to ensure clean slate. Edit: It seems wiping /data and /cache is all you can do in terms of user-accessible data.
I notice there is a "Factory data reset" option from within the OS under Settings: Backup and Reset. Does this behave any differently from the recovery menu method? Edit: I found via thedroidguy.com that it does not reformat the /data partition as the recovery menu reset does but only clears it. It also has Backup and Restore options. Are there any other differences? Does it clear other partitions than /data?
Also, I notice in Settings: About Phone: Status there is "Factory data reset". For me, it says "Unknown". I assume this value is a counter, log or timestamp of the last known factory data reset(s). Maybe it is only triggered when the reset is performed within the OS, but I have no idea. Anyone know what this really is? Will a recovery menu factory reset trigger it?
Under Settings: Storage there is Cached Data. If I clear this, does it include all application cache -and- all application data or just the app cache? Edit: I am pretty sure now it just clears all applications' cache, so it shouldn't affect anything unless maybe an app is poorly coded and stores things in cache that should be elsewhere. On a related note, when clearing app data from apps individually its app cache will also be cleared. I am not sure if clearing Cached Data from this Storage menu touches the system cache partition.
Any documentation or links would be very much appreciated; I am running out of steam here sifting through search results with different keywords and modifiers.
If anything I said is wrong or not entirely correct please say so!

Hey everyone,
my op10pro became extremely buggy, system settings aren't being saved after reboot, the ui is becoming jank af, i am getting no notifications from any apps, popups are getting blocked... very annoying ****.
how can i fully format my entire system and start from scratch ? i am rooted.
i don't mean a factory reset, i already tried that. something that cleans deeper.
thanks in advance
Install a rollback package, maybe it helps (will install Android 12) or install the latest full package and format data.
I don't necessarily want to go back to an old version of Android, and i fail to see how it would help.
How do you suggest i format data ?
You can format data in recovery mate.
Or if you want a whole new OS then fastboot enhance (FE) will do it.
You can format using fastboot too but FE takes care of that.
PS: if you're restoring your apps after a wipe then that could be why it's buggy, let the system install then see how it feels, then restore only what you absolutely need.
