[Q] Please I really need help with locked s2 - Galaxy S II Q&A, Help & Troubleshooting

Hey everyone .
I have a problem here ...
My little sister was trying to unlock my s2 and tried too many times.
Thing is that the Google account i used on the device is very old and I have no clue what is the username.
I was thinking if maybe there was a third party app or software (PC) to use in order to access my data from the PC without having to unlock the phone so that I can back up my data from the internal storage and wipe my phone to use it again.
I have documents I really need on the phone . Please help !

How on earth can you have a google account assigned to a active device but not remember the email address of it?
I cant really see how that could happen, especially on a active device that has important files on. Also why didnt you simply store the files on external or make backup copies manually or automatically?
If the files you need are in custom folders on internal card (you created the folders yourself) then you don't need to worry. Simply reboot into recovery mode and use the wipe data/factory reset option.
WARNING: Do not do above if the device is currently on Samsung Android 4.0.4/kernel.
If you have a custom kernel installed you can simply reboot into recovery and use the mass storage option to mount cards to PC. You may be able to do this in stock kernel aswell, not sure as haven't ever really used stock recovery. Alternatively you could put a signed cwm zip on your external (via a card reader) and then flash it via stock recovery to get CWM recovery temp so you can mount drives or wipe data/factory reset.

Yes I know that was very stupid of me . Thing is my main phone is an htc sensation xe which I use more often.
The files aren't supposed to be on custom folders since I never created any folders on it .
I'm using the stock kernel by the way . I guess I'm really screwed .

Newbie questions - please help!

*Sigh*
I’m a newbie (more like retard) when it comes to this whole update android, leaked Rom’s, recovery, root etc. Can someone please help me get some clarity?
1. Will there be a problem if I try to install the official 2.1 update when I have a rooted phone and Villain 3.4? (No stock 1.5 ROM available via nandroid since I didn’t know what I was doing at the time I first updated it).
2. What is the simplest way to change one's recovery ROM? Do I have to use this whole adb/fastboot (whatever that means) and mess around with things I don’t understand and probably brick my damn Hero, or is there a simple way á la download-copy to SD-click install? The things written in hXXp://forum.xda-developers.com/showthread.php?t=561124 makes me nauseous!
3. What do the terms "Dalvik-cache" and "SD:ext partition" mean, and why would i want to wipe them? (Found them in the wipe-section of my recovery ROM: RA-hero-v1.5.2). Am I supposed to wipe these as well to do what “nprussel” (hXXp://forum.xda-developers.com/showthread.php?t=622468) calls a “full wipe” or is a reset to factory enough?
4. When using nandroid, what is the difference between "nand backup", "nand + ext backup" and "BART backup"?
5. What do you gain from partitioning your SD-card?
To those of you who care to answer my questions – thank you!

From one noob to another, I'll *try* to answer what i can.
1,... Having a custom ROM will not stop you from being able to get 2.1 when it is officially released. I'm sure everything you need will be posted somewhere for easy access. But if you want to download from HTC's website you may need to flash one of the stock ROMS first. You can find all of them at http://android.modaco.com/content/h...oms-radios-in-update-zip-format-for-gsm-hero/
I reckon using one of the HTC generic ones would be your best bet.
2,... This is the method I used:
I. Installing a recovery image:
1. On your phone, go to Settings > Applications - and make sure "Unknown Source" is ticked.
2. On your phone, go to Settings > SD card and phone storage - click Unmount SD card.
3. Then click Format SD card.
4. Plug the phone into the computer via USB, then pull down the notification bar and click on the SD card notification. Then click mount.
5. Download this APK and recovery image and save it to your computer:
hxxp://zenthought.org/content/project/flashrec - FlashRec.apk
hxxp://forum.xda-developers.com/showthread.php?t=561124 - Amon_Ra’s Hero Recovery Image
6. Copy them both to your SD card (do NOT put them inside any folders on the SD card, just put them on the SD card itself).
7. Unplug the phone from the computer once they are downloaded to the SD card.
8. Go to the Market and download ASTRO File Manager or any file manager program if you do not already have one.
9. Open the file manager and find the FlashRec apk file and click it and choose open app manager and then install it.
10. When it is installed click Open. Click on Backup Recovery Image and wait for it to finish. If you get "backup failed" response see the "Ib. Installing the correct HTC ROM" section for more details, if the backup is a success carry on.
11. Once done, click on the empty text box in the FlashRec program and type:
/sdcard/recovery-RA-hero-v1.6.2.img
(replace exact name as new versions come out)
Then click on the Flash Recovery Image button and wait for it to finish.​
... Big props to BTDAG for those instructions. (from http://forum.xda-developers.com/showthread.php?t=645253 -- [Guide] How to Root & Install a Custom Rom on Orange UK & T-Mobile UK [Updated 13/03])
3,... I think a full wipe would be select Wipe Data/Factory Reset, then select Wipe Dalvik cache, then Wipe SD. This is an assumption as they were the steps I followed. (Again, from BTDAG's thread)
4,... Sorry, ain't got a scooby. No Idea.
5,... I think it does something like setting aside a specific amount of room for system files. Some ROMs need partitioned SD cards for the Apps2SD function to work.
I hope some of that helps,... Peace.
Nandroid backs up your phones image (i.e. like a photo of how your phone is on that day)
Nandroid + ext also backs up your ext partition on your sd card (only used if you want to activate and use apps2sd)
Bart is another backup utility, not sure what exactly it does as I have only ever wanted to/needed to use nandroid.
You only need to partition your sd card if you wish to use Apps2SD.
- basically what this does is give you the ability to save and run apps from your sd card as your phone has a limit on how many apps it can have (in file size not number of apps) so if your someone with hundreds of apps then you need to use this but the majority of us don't need to worry about it.
If you root now and want to remain rooted then don't install the official 2.1 it won't take long for a pre-rooted version to come out (a matter of hours) so just wait and install the pre-rooted one
ddotpatel, Lennyuk - Thank you! Your help is greatly appreciated!

[Q] Ice Cream Sandwich Full Device Encryption and Flashing

If one enables full device encryption in Ice Cream Sandwich, am I correct in assuming that that the internal SD of that device is now not going to be available in the CWM recovery mode? And even if it was, the root fs would not be available? If so, this pretty much would make CWM flashing your device near impossible?
Does CWM even work if you use FDE? Or is it planned/
The question I guess is, when do you input your encryption password? Is it some pre-boot step?
I really want to enable device encryption but I can't find enugh details on how it works.
I did read this post on it., but it doesn't really answer my questions. And it is unclear if it encrypts the internal SD, or just the root FS?
http://source.android.com/tech/encryption/android_crypto_implementation.html
No one knows anything about this?
I got a Gnex today from Verizon in the US and I encrypted my phone after I unlocked the bootloader but before rooting. As a result I don't think I will be able to root because it doesn't seem that the modified boot.img that the instructions tell me to use can mount the encrypted system (it sat at the Google logo w/ the unlocked icon for 10 minutes before I pulled the battery and let it boot the stock boot.img) which came up fine.
It seems the only way to decrypt the phone is by doing a factory reset.
That's all I know. That being said, while a custom recovery may work for wiping partitions (such as cache), it would probably be mostly useless until the custom recovery is updated to support the encrypted file systems. I'm a *NIX user and an engineer, but don't have a lot of experience with Android's internals, so take all that with the appropriate sized grain of salt.
Regards,
Chris
Bump.
Anyone experimented with full device encryption / ROM flashing / SD Card? I'm curious about this as well, but not curious enough to experiment.
I dident try it myself, so i dont exactly know, how this works. But i think device encryption shouldent completly block clockworkmod recovery.
I think it could be a problem to make a backup while your device is encrypted. But i think it shouldent be a problem to recover a old system over an encrypted one. Encryption keeps people without the key away from reading data. This dosent mean you cant wright something over it and replace the locked data with some new one. But then you defenitly loose the old data. I dont think you can flash a new ROM or a recovery without a full wipe. You probably gona loose all the data you had on the old system.
But i general i think this is anyway a good think to do when you flash a new ROM.
I think you could give it a try, without briking your phone. But i dident try it, so i cant take any responsibility.

I sonst exactly know hat diagnostic Mode you mean. Depends hat Diagnose you want to run. Do you want to read the logfiles in your phone, wher you can see what ist doing? You could use the app alogcat. An other way would be to run logcat over Eclipse.

I encrypted mine after flashing the stock ICS 4.0.3 image and rooting. CWM still loads, but when I try to use USB mass storage, windows tells me it needs to be formatted before the SD card can be used.
You can use titanium backup to make backups of your stuff, and restore them to a non-encrypted phone. I have found no other way to unencrypt the phone than factory reset either. When you encrypt, then go to settings > security > encryption, it just has a greyed out area saying "Phone is encrypted", which is stupid and needs to be fixed.

So if I factory reset the device from CMW I will not loose my pictures or TB in the internal SD?
What about flashing a new ROM?
Thanks!
I have been playing with ICS + FDE for several days doing different things. First off this is:
Nexus S 4G, running Pete's crespo4g OTA ROM
I flashed with CWM which is still on there and runs fine.
However: /data and /sdcard and /system (?) are encrypted and CANNOT be mounted.
To restore you have to 1) make a full backup over USB to a PC of the whole SDcard (or at least the important folders).
2) wipe and reformat everything. This isn't just a factory reset, this kills the sdcard as well.
3) mount (hopefully) the newly reformatted /sdcard and blow your backup from the PC onto the /sdcard
4) use CWM to restore a previous ROM.
That's pretty much it, give or take. Not for the faint of heart. However, if you are concerned enough to want encryption, you don't want to just say reboot recovery and voila all your files are belong to us, right?
---------- Post added at 03:58 PM ---------- Previous post was at 03:34 PM ----------
Also, the backup to PC part is just your sdcard. It doesn't back up the whole system. There might be a way to do that via adb, I don't know.
So i am running rooted runnig miui.us rom. I just tried to encrypt phone.. It ran for 2 and a half hours and I got impatient. thinking maybe i shouldnt have done it... Then after a little bit of panic i said **** it if i lose data i lose data... so i powered off and back on hoping i didnt and the rom booted back up with all my data intact..... •••••• Wish I had more to report but im not doing that again until someone can confirm that it works fine...... I have tried booting into cwm yet.. If i have an issue when i need to boot illl report back but if you dont hear from me here then assume I was able too.
Pete's to CM9 - still encrypted
IT does indeed take a fairly long time to encrypt. If I understand correctly it will build the encrypted partition on a loopback (or something like) before erasing the original (by overwriting?).
I've got more to report. I followed my plan (couple posts back) for unencrypting and reflashing my phone. (Nexus S 4g).
The first bits of this worked fine. I was able to flash CM9 onto my phone (works like a champ btw). While the phone was in recovery I mounted the SD and copied my backup back onto it.
However...
When CM9 booted I STILL got the "unlock your device" screen, still the same password, and it decrypted and booted. That was surprising, but not as much as when I looked for the SD card, it said it was incorrectly formatted! The only thing to do was reformat and copy with the phone on and unlocked.
So lessons learned: 1) a factory reset from _inside_the_ROM_ doesn't remove the encrypted partition at all and
2) As far as I can tell, the SD card _is_ encrypted along with /data
I'd be very interested to hear other's experiences, especially someone who can remove their SD storage.
Undoing FDE
First off - Lacking a device with removable storage to test with all I can tell you is that the sdcard is not accessible by any normal means after FDE is enabled without booting into the encrypted system.
"Removing" FDE required three steps beyond normal:
-Factory reset from within the ROM
-factory reset/wipe at recovery and/or format /data
-once into a running ROM, reformat the sdcard
Once all that is done (in addition to normal setup for ROM) you should be able to operate normally again.
problem with encryption on sgs2 with android 4.0.3
I really want to enable my device encryption too, but I can't !!!
the phone start encrypting after he ask me for a new secure password, rebooting and asking again for my password and surprise!!!.... the password is not match ?!?!
I repetead these steps for 3 times but the same result...the password does not match!!! ?
Please, if someone found a trick to repair this inconvenient, tell us in this post steps to be followed.

GT-I9100 cwm / cm13 bootloop - data recovery?

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.

You can access safe mode that means an app is causing this.
I would Guess It would be facebook.
Now Boot to TWRP and Delete /data/data/com.facebook.katana and /data/app/com.facebook.katana.
Reboot your device.
If that don't work for you Try Using MTP.
If you don't wanna do that.Take an SDCard Insert in the phone.Boot to recovery.
Move the files manually.
Painful but good.
If not A SdCard Slot is present then Try an OTG.
After recovering your data.Do a Full Restore and do a Nandroid Backup.
You are Using Custom ROM!!!!!!!
You are supposed to be taking More Precautions and being less Dumb than other Users.

Second i want to backup each and everything before proceeding ahead so can you suggest any s/w , tool to backup data on PC.
third as i said i am lay mean who donot understand all this "boot to twrp" or "MTP" or "Nandroid Backup"
If can provide me steps or links to it i would definitely try it

You have To install a Custom Recovery In order to go further.
Install a Custom Recovery Like TWRP or Team Win Recovery Project.
A custom Recovery is similar to Normal recovery that comes with Stock Android Recovery known as Stock Recovery.The question Might arise that why Custom Recovery but first We Must Come To know That What a Recovery do and How does it become "Custom".
Android recovery is a Program embedded in a part of android storage that helps us to recover restore backup or Flash System Packages.
A Stock Recovery would only flash OTA updates that are signed by the system only.More the stock recovery Would Not be able to do Some functions A Power user requires.
Now the answer to the previous Question That " Why Custom recovery" It's because a stock Recovery can't move files and Make backups called Nandroid backupup.
Now a Nandroid backup is a Backup a Tester or a Power User would Usd to save His A.S.S in Times he Would do something that causes something like you have encountered.
Now A custom recovery Can only be Installed via Flashing From A PC using Odin.
Find the Custom Recovery For Your Device Named TWRP.
Choose very carefully this could destroy Your device PERMANENTLY
After finding Your Device specific TWRP recovery once again make clear it is Good for your device.
Check The Whole File name.
It should have A Name Like "Revovery.tar.md5" remember it should have an "tar.md5 or similar" ending if it don't have that format find again a different Version or use a different web to download it Now Flash It Via Odin.How?There are loads of Videos on Youtube Find "How To Flash TWRP via Odin On Any Device"
After getting A TWRP recovery on your device It's time for you to "Boot to TWRP" Here boot means Directly going to a specific Programes like Bootloaders Recovery Download Mode ETC.
Find or Borrow a Card from a Friend or Someone.this would not take long.
It would only take half an Hour.
Now Boot to TWRP.
After booting to TWRP.
There would be many Options.This page is Called TWRP HOME page.
Click on Advanced.
It would open other option.
Click on File manger.
Now There would be a File Manager Simmilar to Root Explorer.
This is Time We Recover your Data.
Find Sdcard from the list click on It.
Then you would See your internal Memory.
Now Go to the folder where you kept your Images or anything
After arriving to that folder click on the floating little folder icon On the Bottom Right of the screen with a Tick Mark on It.
After clicking on it
It would Open A Series of options.
Click on copy or move.
After clicking go back to The Root Directory(The First Screen you got after clicking on File manager is called root directory)
There you should Find a List of folders.click on Storage Then extSDCard.
Now again Click on the floating Folder icon with a TiCk Mark.
It would again Open the Same Screen as Before Select paste.
Now you have just moved a Folder of your data from internal memory to extSdCard.
Go back To the root directory and Repeat Step 1 to End to recover 1 folder per Try.
After recovering all data.
Remove your sdcard Transfr data to pc.
Go to TWRP home.
Select Wipe.
Click on advanced Wipe.
Tick Cache.
Tick Art Dalvik.
Confirm your action.
Reboot The phone.
If it does not Solve the stuck at screen Problem then Go to TWRP home Select Wipe and Factory Reset It.
It should Boot now.
There is one question Left.
What is MTP.
It is Called Media Transfer Protocol.
It is used to transfer files from PC to device or vice versa.
Have a Good day and ask me For help If you get Some more questions or are stuck.

Backup images from the phone

Respected by mistake, I reset the phone to factory settings.
So on that occasion I lost pictures, videos, viber pictures, messages and sms.
So I'm wondering how I can get back to my phone or computer.
And is it possible to set the phone as a usb device or sd card so that all the data on the computer is restored to the software (I managed to recover the data from the deleted usb from the usb device using recuva applications and the like)
Thanks

What you intend to achieve requires 1. the phone is rooted and 2. USB-Debugging is successfully enabled. Both requirements fulfilled?

The phone is rooted once but I'm not sure if it's done well.
So I should root it and then try with some apps to find the lost files in the phone?

I apologize: Device must NOT be rooted.
Carrying out a Factory Reset all your device data get wiped out, means you end up losing all your important user data before it is backed up. However, Factory Reset does not affect the external SD-card in any way. So, even if you have the SD card inserted with videos, images, documents and any other personal information in the Android device while carrying out a Factory Reset, everything will remain safe and intact.
Factory Reset is neither the best option anyway.
As long as after the Factory Reset no apps etc.pp. got installed on Android device, there is a chance you can recover deleted user data - but only if the related storage memory didn't get overwritten in between. So instead of recovering deleted files from Android without computer by an Android file recovery app, which could potentially overwrite the deleted files when the app is installed, you have a better chance to recover the deleted files with a desktop Android data recovery application on your computer. Dozens of those Windows applications are available, simply do a Google search for those.
I tried the root phone but failed.
Does anyone know how to root this model?
Thank you
