[Q] Rescue encrypted device that bootloops - Android Q&A, Help & Troubleshooting

I have my device on cm10.1 encrypted.
Now as I am an idiot unsuspectingly enabling a debug option: "Simulate Second Screen"
My device is now bootlooping after keyentry.
As I am an idiot I do not have a current backup.
But as I never give up on such stuff:
I want now to do the following:
Get into recovery
put a line into init that:
copies the file where this setting is stored to /extSdCard/whatever
reboot, enter key and wait
enter recovery
change that config file to my turn off that evil option
edit initlines to overwrite settings with the changed settings
reboot
Now:
Can you tell me in which config file that "Simulate Second Screen" setting is stored?
Where in init.rc should I put my rescue instructions to get executed after /data and /exSdCard is mounted?
findings:
the content of the rootfs seems to mostly kernel created and behaves differently in recovery.
the /system/etc/init.d/00rescuescript did not work either because its executed later than where the boot loops.
BUT:
I found a way simpler approach.
I didnt know CM roms have a safe mode, assuming they are stock rom things where the recovery is castrated.
Now with that the setting is ignored, switchable and all is good.

Installing BMM 0.3.0f

I am trying to install BMM 0.3.0f so I can install CM10.1, but it is not working.
WhirlEyes' instructions are to download it to the sdcard, unzip, and run install.bat. When I run Terminal and try to execute install.bat it says Permision denied. Well I am su # and permissions on the file are 750. I # chmod 777 install.bat and it seems to have worked, but I ls -al and the permissions are unchanged, and I still get the error.
Has anyone been able to install this?
And BTW, now that BMM is shut down, do you suppose that SafeStrap could ever possibly be as good?
Personally I hope that, if WhirlEyes no longer wants to mess with it, that he will pass along all the goodies to someone who does. It took up alot of his time and he is tired now, so pass it along to someone who has the time.
First, make sure you have the correct Driver installed. Enable USB Debugging and start the bat. On your RazR you'll see Super User pop up to ask for Root rights. Allow it and it should work flawless.

Well it sounds like you're saying do it from the PeeCee. I've been trying to do this on the phone.
# adb devices
... doesn't see it when the phone is regular running. I rebooted to fastboot mode, and still it is not seen, although on the phone it says USB Connected. I do have USB Debugging On.
I can't believe there aren't any directions on this, even in the BMM thread. (now dead)
Edit: Well I've figured out that adb will only recognize the phone when plugged into the RIGHT side of this Elitebook.
So now I tried to execute install.bat again, but still Permission Denied. I thought maybe it was the way I unzipped the saveset before (with Thunar), so this time I did it on the commandline. Same problem. So I resorted to executing each of the install.bat commands by hand, and all was fine until I got to:
# adb shell "su -c 'cp /tmp/bootmenu.prop /system/etc/bmm/conf/bootmenu.prop'"
bootmenu.prop is not in /tmp. Maybe this is my old setup file for BMM 2.6.7 (or whatever it was). I don't know why it's not there, and I'm afraid to do anything on the phone until I get some kind of confirmation. Can anyone advise?
Well I took a chance and rebooted, and to my surprise I am now running the new BMM on boot.
But when the phone comes up in MIUI, the 0.2.7 app is still installed, so I removed it. There is absolutely no apk anywhere in the zip file. I tried Boot to Recovery|SystemKeeper|InstallBMM, but that doesn't work.
Again, there is no next step.
Also there seems to be a radio updater, but better not touch that as different radios in different parts of the world.
Maybe I just have to learn friggin' SafeStrap.
Nobody has the 0.3.0f app installed? How do you set up the image for second boot?
There's no App for 0.3.0f!
After rebooting your Device you'll see the Hijack showing the different Rom Slots. At the bottom is an tab called settings. Hit it. After that select System 3 (System 2 got an issue with the Cache Partition)
Now you'll see 2 tabs. First select the left (Partitions) and create all 3 (System / Data / Cache) You can choose the size of the Partitions, to fit your needs. I usually set 500mb for System / 1000mb for Apps / 500mb for Cache)
After you have done that go back and select the right tab (boot options)
Uncheck all boxes.
Now if you decide to flash CM10/Aokp, set the 2nd init. If you 'll flash MiUi or Stock based Roms, select nothing.
If you wanna use the HotplugXtreme Overclock Modul on your Rom select the OC.
If you flash KeXec select 2nd init and KeXec.
Ok, now the System 3 is prepared to flash. Go back to the Main Screen and select the Recovery. When you're in there, switch System to System 3 (Stock System is always colored RED!) So if the tabs are red you mess around with your Stock Rom.
After you switched the System, just flash the Rom as usual.
During Reboot hit System 3 and you' ll boot into it (Default boot is Stock System)

Is this allocating space on the internal sdcard? Is it possible to set it to the external one? My internal sdcard is fairly full.
It looks like it is creating a file for system, cache, and apps which are mounted in loopback?
Edit:
Well I was able to boot to the third slot once...
Then I booted to the first slot, and then back to the third and this time it's locked up. I have the green Android with gears, red LED, and the last entry is ... Booting.
Stuck for an hour. No phone. I guess I have to wait for the battery to die. Worried to try this again.
..
Now I have CM10.1 installed to the third slot and it boots. But it is not finding my Titanium backups from the first slot. How do you transfer backups from the first slot to the third? Is the third just a file that's mounted loopback?
OK I guess this isn't going to work. Nobody else here is doing this, and for the second time my phone is locked up on the geared-Android Booting screen. I have to wait hours for the battery to run down with the phone off the air, and I just can not do this anymore.

[solution] How to recover from bad overclocking settings

I recently was experimenting with overclocking settings and stupidly left "Set On Boot" option selected. When I tried setting the max cpu frequency setting to the maximum (864MHz), my phone promptly crashed.
Because "Set On Boot" was on, the phone crashed again after rebooting. I was basically stuck in a crash-boot loop.
You can recover from this by formatting the /data partition, but I didn't want to lose all my app settings.
So here are some rough steps to turn off "Set On Boot" via CWM Recovery and the adb shell.
1) Reboot into CWM recovery (repeatedly press back during the kernel boot animation)
2) Under the mounts and storage menu, mount the /data partition
3) plug the USB cable into a pc that has the android tools
4) On the pc, do "adb pull /data/data/com.android.settings/shared_prefs/com.android.settings_preferences.xml"
5) open the com.android.settings_preferences.xml in an editor and look for
<boolean name="pref_cpu_set_on_boot" value="true">
Change this to "false"
6) Save your changes and push them back to your phone:
adb push com.android.settings_preferences.xml /data/data/com.android.settings/shared_prefs/com.android.settings_preferences.xml
Reboot and go back to your settings and fix them.
This is very useful information, maybe a mod could make this a sticky post or it can be included in some faq posts, so it doesn't get lost in time.

State of Nabi 2 Root as of 12/14?
So I have admittedly been out of the loop on the state of rooting my two Nabi 2s since after I restored them to stock and all back last year when they released the update that included the Gapps. So I've been running stock since then and am on the latest firmware (2.4.6 I believe). All is mostly fine, but I would really like to get the external SD cards to be writable again, and from what I can tell, I need root again to do that.
So...as of today...what is the state (and best procedure) of rooting the Nabi 2 on the latest OTA update? Is Nabi Lab still the best tool? From what I've pieced together from scattered threads, it's looking like possibly use Nabi Lab to install TWRP, and then use that to install the SuperSU (http://forum.xda-developers.com/showthread.php?t=1538053). However, I could likely be wrong...hence why I'm asking.

Nabilab will still work as long as you use a version with a Jellybean TWRP(since you are on 2.4.6).

Stock Restore
Hi
I have downloaded NabiLab, as I am having wifi issues on my updated Nabi2. I unzipped, ran the .bat and chose option 3 (with my nab connected via USB). Nothing happened, no errors etc, the screen flashed up and shut down. Do I need to do something with the Nabi (recovery mode etc), do I need to install anything from NabiLab before trying this? Any help would be appreciated

What version of software? Use Nabilab2015 http://forum.xda-developers.com/showpost.php?p=59073456&postcount=2544
It has more diagnostic info. Just be in Android or TWRP with ADb enabled. It also can see if drivers are loaded.
Hacking Nabi2 to Allow Data2SD
I managed today to hack my kids Nabi2 to enable Data2SD. I was to frustrated by the limited space in the tab. My kids were complaining about not being able to add more games. Thus, I decided to take the risk of modifying the mount points of the tab to allow the data partition to point to a partition in a large sdcard, instead of the limited 4.5 GB space in the internal storage.
Warning: I am not responsible of any damage as a result of following the next steps. Always make backups
Note: I have the last update (KitKat) installed in the Nabi2
1- Dump the boot image from an adb shell:
Code:
su
cat /dev/block/platform/sdhci-tegra.3/by-name/LNX > /sdcard/boot.img
2- Open this url http://android-dls.com/wiki/index.php?title=HOWTO:_Unpack,_Edit,_and_Re-Pack_Boot_Images
to see the instructions of how to unpack and repack the boot image. Note that, the splitimage script mentioned in the page can be found at https://gist.github.com/jberkel/1087743
Warning: do not do anything in the tutorial, just wait
3- Format an sdcard as one partition of ext4 type
4- Insert the sdcard in the nabi2
5- Use the tutorial in step 2 to extract the ramdisk contents from the boot image and then Modify the file "fstab.mt799" in the ramdisk folder by replacing the line
Code:
/dev/block/platform/sdhci-tegra.3/by-name/UDA /data ext4 noatime,nosuid,nodev,journal_async_commit,data=writeback,nodelalloc,errors=panic wait,check,encryptable=/dev/block/platform/sdhci-tegra.3/by-name/MDA
with
Code:
/dev/block/platform/sdhci-tegra.0/by-num/p1 /data ext4 noatime,nosuid,nodev,journal_async_commit,data=writeback,nodelalloc,errors=panic wait,check,encryptable=/dev/block/platform/sdhci-tegra.3/by-name/MDA
which switches the data partition mount point to be on the sdcard
and the line
Code:
/devices/platform/sdhci-tegra.0/mmc_host/mmc2 auto vfat defaults voldmanaged=sdcard1:auto
with
Code:
/devices/platform/sdhci-tegra.3/mmc_host/mmc0 auto vfat defaults voldmanaged=sdcard1:12
which mount your old data partition into the directory of the external sdcard
6- Repack the boot image as mentioned in the url in step 2
7- Copy the new boot image to the nabi2 sdcard
8- Once you copied the new boot image (e.g. new_boot.img), replace the current boot image with the new one using adb shell:
Code:
su
cat /sdcard/new_boot.img > /dev/block/platform/sdhci-tegra.3/by-name/LNX
9- Now the kernel is replaced and once you rebooted your external sdcard would be in use, but note that your device is now having an empty data partition on the external sdcard, so you have to setup everything from the beginning. Note also that your previous data partition is now mounted as an sdcard, however, you have to format it from ext4 to fat32 to work as an sdcard (you can do the format from setings->storage->sdcard format)​

Hi, I purchased a reconditioned Nabi, which was reset back to stock. The wifi worked fine, until I updated it through the tablet. I am now on version 2.0 with no wifi. I have tried various options through NabiLab , however my Nabi is not recognised as being connected (although windows picks it up). Please help!

That's weird...if you keep messing with it you may find a spot a little left, right, higher, or lower where you can grab the button to swipe....or you try to re-flash TWRP or maybe there's a new version of TWRP for your particular nabi software version.
did you ever get nabilab to see it? did you check the device manager to see if it was totally recognized? Are developer options enabled?

The Nabi is showing as a device, it's responds as it should up to the point of TWRP. I had to repeatedly press buttons to get to the restore swipe and have tried many times, unsuccessfully. Where do I enable developer options?
I am on version 2 (Nabi) and using the most up-to-date version of NabiLab. I am trying to restore to stock so that the software version goes back, as the update has stopped my wifi working. Even a factory reset doesn't take the Nabi software back further than v2.0

For developer options you go to settings, scroll all the way down, if you don't see "Developer options" there, press About tablet, then repeatedly tap build number until it pops up and says "You are now a developer!", then go back and now you should see the Developer options menu item, press it and then make sure it's on at the top and that the USB Debugging option is checked.....then try nabilab again.

Well, the touch issues are probably due to a bad build of TWRP but not necessarily the wrong one. The problem with nabilab not being able to see the tablet I think has to be drivers. Have you checked device manager to make sure there are no unrecognized things? 'cause the tablet show up as two separate things in there and it sounds like the USB storage part is working but not the adb and/or fastboot part(s).

I've managed to sort the drivers by installing PDANet, then managed to sort TWRP by installing an older version. I've now updated to 2.1 on the Nabi but no luck with the wifi issue..i'm guessing it's really broken and it happening whilst updating may have been a coincidence?!

It might just be broken but that's a heck of a coincidence... Do you have a backup from before the wifi issue started? If so, I'd try to thoroughly wipe everything but your external sd card and then restoring your backup and see if that helps.

Gapps/TWRP/CWM on china tablet

Hello,
I recently got a hand on Yuntab K107, ARM MT8752, Android 5.12 Bootloader unlocked. Everything worked fine until factory reset, after that Google play store and other gapps stopped working (play store checking info, then goes black and freezes for a while).
Tablet is rooted from factory by kingroot, I tried finding TWRP/CWM for this tablet to reflash gapps but I failed. I also tried Magic TWRP installer and MTK droid tools. Magic TWRP installer acts like it's working but no results. MTK droid tools refuses to find my device even if i tried every driver possible and cleared wrong drivers with USBDeview.
I also tried flashing gapps manually thru root explorer by unpacking gapps files and matching system file structure also no luck.
Then I backed up the stock recovery and tried flashing few custom TWRP's that some post suggested may work (you guessed it - it didn't work) It just hangs on the first booting screen then it surrenders after a while and reboots back into android.
Do you know about any TWRP/CWM that might work on this tablet or any other way to repair gapps if recovery is not necessary?
Thanks
I also rooted it with kingroot but havnt any custom recovery but i doing some experiment. Let se what it will result
I should be able to compile TWRP for you
I have one of these K107 tablets but it is running Android 7 and so far I have been unable to root it. Because you guys have root you should be able to download adbd Insecure by chainfire and follow this guide to Fetch the boot.img file by Extracting the boot.img directly from the device:
you will first have to determine the (sadly device-specific) path to the storage device where boot.img's content can be retrieved. I know two methods for this:
ls /dev/block/platform/*/by-name/ (where * covers yet another device-specific folder name, chances are it is the only directory below platform/), the exact name to search is also platform dependent but makes usual sense (some examples: boot, LNX (acronym for "Linux")). The files in this directory are actually symbolic links and some people bother to manually go to the target, but I recommend sticking with the higher level name based path which, while longer, remains less error prone. So you will end-up with a path like /dev/block/platform/sdhci-tegra.3/by-name/LNX.
On some (older?) devices, the right device could be found by investigating the output of cat /proc/mtd. If you see the device mtd2 associated to the "boot" label, then you will use the path /dev/mtd2.
Now:
From the phone's developer menu:
Enable debugging on your phone,
Allow root access to ADB (this step applies to phones running CynogenMod, other devices may require some potentially more complex procedure),
Connect it to your computer (and from there to the VM guest if you are running Android tools from within a virtual machine).
If this is not already done, I recommend to manually start the ADB server on the computer's side, this will allow you to directly validate the RSA key on device's side without affecting the behavior of the following ADB commands:
adb start-server
Then switch ADB in root mode:
adb root
Finally, you should be able to directly extract the boot.img file from the device using such command (the source and destination path and names are given as examples, adapt them to your needs and preferences):
adb pull /dev/block/platform/sdhci-tegra.3/by-name/LNX ./boot.img
The command will copy the whole partition, both used and free space, so don't be surprised that the resulting boot.img file will be larger than the original boot.img file coming with the stock ROM .zip file, the content itself remains similar.
Once the transfer is finished, disconnect the phone and don't forget to disable both debugging and root access from the developer menu.
Then upload the boot.img and I will build TWRP and test it on my tablet for you

Razer Phone 2 soft bricked after applying GPS Joystick GPS disabler

I have a Razer Phone 2 rooted with magisk. I use GPS Joystick. I decided to select the "disable system GPS" setting in its options. I rebooted as the app requested and now my phone loads to the point where it wants me to enter my pin and I see my wallpaper for a split second then the screen goes black and it loads up the status bar about ever 10 seconds for a split second then it repeats. Like it is stuck in a loop. After a couple minutes phone reboots and I get this message...

So I reached out to the dev of GPS Joystick and he explains that the option disables the location services called "fused location provider" and I have to re-enable it to fix the problem. He sent me a post here explaining that I need to pull an .xml file from the phone, change the code, and push it back. Simple right? Well maybe if I have TWRP, but I don't. I can however boot into the phones recovery options and there is an option there to "apply update from adb" but I cannot seem to pull anything using that interface. My Windows computer recognizes the device using Minimal ADB and Fastboot but it shows it as a whole bunch of numbers then the word "sideload" which I guess is a limited form of adb just for side loading? Maybe someone could make me a script that I can sideload that changes the file back to normal? Here is the code from the dev of GPS Jostick that is used to disable and enable the fused lcoation provider.
It calls this code to disable:
ComponentName component = new ComponentName("com.android.location.fused", "com.android.location.fused.FusedLocationService");
getActivity().getPackageManager().setComponentEnabledSetting(component, PackageManager.COMPONENT_ENABLED_STATE_DISABLED, 0);
And similar code to re-enable it:
ComponentName component = new ComponentName("com.android.location.fused", "com.android.location.fused.FusedLocationService");
getActivity().getPackageManager().setComponentEnabledSetting(component, PackageManager.COMPONENT_ENABLED_STATE_ENABLED, 0);

So my question is, can I pull this /data/system/users/0/package-restrictions.xml file from my phone and push it back without using TWRP? But instead using the phones recovery option and its various selections? I'd prefer to exhaust the resources to recover the phone since I have spent weeks personalizing it. I am not fluent in adb but I am hoping someone can throw some ideas or even a solution at me that I am missing. All I got to do is pull a file, change a word, push it back and reboot. I can't imagine there isn't a way to do this by just using what the phone has to offer. Any help would be greatly appreciated.
Another idea that came to mind is in its current condition could I install TWRP? Is fastboot an option at this point? Maybe if I can flash TWRP in its current state I can then make the appropriate modifications.
I ended up fixing the problem. I installed arter97's kernel that had TWRP baked into it. I then used TWRP to copy over the .xml file, change the code as mentioned above, and then copied it back to the phone. Problem solved. It is amazing how one simple word in a .xml file can prevent a phone from functioning properly. It simply amazes me.
