Hi guys
I just changed my color of everything in recovery mode. My phone has been trying to start up for 40 minutes! I don't know what to do. Can I remove the battery and try to turn it on again? I just want it to startup.
Thanks
i guess you are stuck in a bootloop. you should have made a backup, did you?
I'm not really sure what a backup is? I have titanium, and clockwork I believe on my phone. I have changed the os a few times. Please explain to me what a backup is
Backup (Nandroid) is a part of clockworkmod recovery.
usually before you flash anything that changes the system files, you should make a backup (takes less than 5 minutes). just in case something goes wrong with the file you flashed, so you can revert back to how the phone was before the backup.
are you stuck at the splash screen or bootanimation?
I just removed the battery, and I put it back in and it's doing it again... I hope it starts up.
You are the fifth person I saw having this problem today. Something is not right here...
I am guessing chrome beta is causing this. I didn't get a chance to do factory restore yet as I want to backup my data files first when I get home.
But someone said data wipe and factory restore do not help...

i highly doubt that Chrome for Android is the source of the problem.

I am on stock rom without root. There wasn't any issue before and installing chrome was the only thing I did yesterday.
By changing the color what do you mean? Flashed a theme?

which process did you use to root your phone?
So basically something from that theme didn't install correctly and is not allowing your phone to boot.
When making any changes to anything it is always wise to make a nandroid backup. If you made a nandroid you could restore that and you would be fine.
Since you didn't you have 2 options.
Option 1) Flash the current rom you were running with just a dalvik cache wipe and hope that it boots back up. If it does not you will have to do option 2.
Option 2) Wipe both data and cache and then flash a rom. You will lose all of your data but, you will then have a working phone.
I installed the chrome earlier today, a few hours later i got stuck in reboot loop. I use adb pull to get a copy of important data.
factory reset doesnt work. when i try to flash an earlier image of my phone, it fails at restoring 'data'
Hi all,
I recently got a HK N7105 and because it lacked the possibility to use a french keyboard I upgraded to a stock unbranded ROM from Sweden (XXDLL1) and succesfully rooted with the relevant CF_autoroot through Odin. Also installed TWRP 2.3.3.1.
Then, I connected the Note 2 to my corporate exchange server which enforced a full encryption policy (device and external SD card) so I had to type in a password at each boot time (with a "nice" swedish prompt that took ma while to decypher), plus a password to unlock the screen. All was well as the root survived the process.
Next I upgraded to a later stock ROM from France (XXDLL4 from SFR) to try and get rid of the swedish prompt. That worked fine (and root was loast in the process, as expected) but I hated the branded stuff so much I reverted to XXDLL1 until a proper unbranded "english" or "french" ROM is available.
At this point I decided to root again. I was running XXDLL1 like the first time and used the same autoroot tar from Chainfire. Except my Note 2 was still encrypted and after that it would not accept my boot password (a four digit PIN) anymore so I was guted and had to factory reset and root then reinstall everything before reconnecting to the exchange server.
Question 1: Does anyone know of a safe, proven way to root a fully encrypted Samsung device so I can go another upgrade without having to wipe the device first?
Why reinstall everything? Why not backup everything first so you can restore after the wipe? Well, it so happens that no recovery (at least neither CWM or TWRP) can read any encrypted media on the Note 2 at the moment. And no Recovery can actually fully backup the device as well.
Question 2: Does anyone know of a proper way to handle this situation with minimum hassle?
So far, the best I can think of is doing a Titanium backup and FTP the files to my NAS so I can retrieve them later. But (Question 3) will this be enough to restore my phone to the expected state after a stock firmware upgrade?
Thanks in advance,
François

I think using Exynos Abuse apk will do the work

Yes that's a way to root the device.
Regarding encryption, very few people on xda seem to use it. So for that reason you'll have trouble finding out what works... I do use it though through choice so I can help you a bit.
When you encrypt the device, just consider /data to be off limits to anything not booted fully. That's why it asks you for your key in swedish - it can't see what language is in use until you unlock /data.
You will have issues using recovery with the device, since they can't read /data. You can use an external sd to perhaps load data to the device though.
I believe that TWRP might soon support the Samsung encryption on the device, meaning you could use it as recovery. Once you have a recovery that supports Samsung encryption, you should be able to consider it a fairly normal device.
Just be more cautious to backup your data as it is hard to recover if something goes wrong...
If your using stock rom 4.1.2, exynos abuse method of root will not work. It's been patched

Fine, I understand. As long as I have a way to recover my data if I need to wipe I'm okay... I just have to hope Titanium backup gives me that until TWRP can manage encruption on the Note 2.
I'm really waiting for a stock rom that boots in English or French now.

I am on Stock 4.1.2 and Exynos Abuse did work on my device, it's successfully rooted using the Exynos AbuseAPK on 4.1.2 :good:
OK, now I have been experimenting a bit with backups and upgrade and have trouble restoring my device fully. Let me explain...
I got hold of a TWRP build that seems to handle Samsung encryption fine through one of the TWRP devs (thanks!), so I decided to go back and try to update my device.
Current ROM: N7105XXDLL1_N7105TLADLL1_N7105XXDLK7_HOME.tar (obtained from Samsung Updates)
New ROM: N7105XXDLL7_N7105OLBDLL2_N7105DXDLL1_HOME.tar (obtained from Samsung Updates)
First I performed a complete Titanium Backup on the device and pulled the files to my laptop using ADB.
Then I restarted into TWRP 2.4.0.0 (got a prompt for my password), performed a full backup and pulled the files to the laptop using ADB.
(for some reason, I could not install the new ROM from TWRP (unable to open ZIP), but the ZIP looked OK, as well as after a second download which TWRP since did not like, so I had to use Odin instead).
Next, I flashed DLL7 with Odin. It worked, asked for the password at boot, but the device was unrooted at this point (I expected that).
Then, I flashed CF-Auto-Root-t0lte-t0ltexx-gtn7105.tar from Odin, but the boot up password would not be accepted anymore as I already knew.
Tried to flash DLL7 again from Odin, same thing
Flashed TWRP back on recovery partition, but on startup it would not ask for password anymore and the external sdcard looked empty to it.
I then copied my backup to a different, non encrypted sdcard and could restore from TWRP but the password would still not work after reboot.
I did a factory reset, restored backup, same result.
At this point I decided to factory reset, wipe Dalvik and format /data. The format did the trick and after TWRP restore of my original back up the device booted up, did not ask for password and all my data was there. Except the Exchange account I use for Corporate email wants me to restore encryption in order to work (I expected that too).
Back at DLL1, so I flashed DLL7 again with Odin (OK), rooted the phone, triangled away the flash counter and reflashed TWRP to recovery.
I was where I wanted to be except for one thing: I need to restore Corporate access. But when I let it encryp the phone it does nothing. I let it through the night and nothing). And if I reboot the phone no password is needed at boot time, yet the phone seems to behave as if it thought the device was still encrypted...
I reflashed my original, full, backup (i.e DLL1) succesfully but Exchange still wants to encrypt my device. Isn't restore supposed to restore the encrypted /data I backed up?
At this point I'm left with possibly tryinjg to go back to full factory settings, not use the backup at all, encrypt the device then restore my data from the Titanium backup I made.
Is there a better option?
[edited jan 18 - TWRP/TB behaviour]
My comments apply to encrypted devices only! I am not trying to talk down TWRP or TB here, as they provide splendid performance on non encrypted devices. I have come upon hard time trying to upgrade/restore an encrypted device using thoise tools, that's all
For those considering upgrading & re-rooting encrypted devices, don't!
I am finding the hard way that this is a one way street. At this point, my TWRP made full backup does not restore the device to the expected status. Each time I apply it, subsequent bootup takes several minutes and I end up going through the initial setup procedure. It seems the device for some reasoin goes through a complete reset procedure.
[edit]
Clarification: The TWRP build I use, 2.4.0.0 is an alpha build and I was not current when I restored my backup. I so happens that it was overwriting the encryption header on the partition, which messed things up bad, and had issues writing back the data partition, ending up in a factory reset status!
Using the latest drop as of today (jan 27) I was able to restore my original backup and am now back to my original state. All is well.
[/edit]
Titanium Backup is none better. It keeps telling me that my Android ID has changed, a host of system applications start to fail when I try to restore and generally speaking I have now spent between a good 20 hours trying to simply restore my data.
[edit]
this behaviour is probably linked to encryption. I know for a fact that TB works very well on non encrypted phones. The 20h figure is overall, not just with TB.
[/edit]
The end story is: root before you encrypt, and either don't upgrade or don't re-root if you do! If you do, be prepared for some rough times...
Unless someone has a cleat idea of how to do this properly without losing all your data, that is.

I have had no issues despite doing upgrades, with and without wipes.
Titanium is fine, just stop restoring system app data. Seriously, what data do you have in a system app that you want to restore.
Restore your user apps, their data, and the xml based call, sms, Wifi backups. It will work fine.
Device ID isn't a problem - it's just trying to help you.

Sorry if I came across dissing Titanium Backup and/or TWRP. This was not the intent... I am sure both tools work real nice in general cases (and I have had success restoring data on a Jetstream before).
My main issue here is _full device encryption_ enforced by my company's corporate IT to allow me on the corporate exchange server. Do you have full device encryption on?
On my device, even after a full wipe and flashing a fresh stock rom Titanium Backup just did not work as I hoped. When I had to confirm individual popups of apps closing unexpectedly while it was proceeding and got nothing back in the end, what was I supposed to think? It could be that I don't understand how TB works... I was neither able to restore missing apps after the flash (missing apps: 0) nor installed apps data (they would close unexpectedly when started after restoring the back up). So I say: until full operation of TB on encrypted devices is documented, I will stay away from it, even though I am a registered user (and I do not plan to seek reimbursment)!
Anyway, I got to a belated happy ending (previous post edited).

Yup I use device encryption Enabled manually, but it's the same encryption.
You should find that titanium shouldn't even be aware of it - the encryption is transparent!
I wonder... I'm sure lenny had that issue on a recent 4.1.2 "stock" ROM... And he doesn't use encryption...
I personally have had no issues with titanium on an encrypted device anyway
I notice you were using the newest rom - that's the one lenny had issues on.

Exactly like I thought, encryption should be transparent to Titanium Backup since it runs within the OS.
I have had problems restoring into 4.1.2 DLL1 (the build I came from) and DLL7 (the one I was trying to go to)
The point is moot anyway since the DLL7 I tried was actually branded (Singtel stuff all around the launcher) and did not include French, which is why restoring my TWRP backup was a tempting proposition.
Good to know TB runs fine with encryption as well. What ROM are you running?

About a backup : have you tried Online Nandroid (Playstore) (or similar, based on Onandroid) ? This makes a CWM or TWRP compatible backup while the device is running (everything should be unencrypted at this moment).
See http://forum.xda-developers.com/showthread.php?t=1620255
About rooting : you can try the same trick as above, by using ADB-shell and pushing the needed files to root to the device while it is running.
For my S3 there is a Toolkit that automates all this (http://forum.xda-developers.com/showthread.php?t=1703488), maybe there is something similar for your device ?
If not, you should still be able to do it using manual ADB-pushing.
I'm sorry I can't give you detailed instructions about the rooting as I'm not familiar with your device. Search here on XDA and you'll find more details.

Thanks for the suggestions, and no I had not tried Online Nandroid as I was not aware of it. Anyway, my main issue is now resolved since TWRP has include support for Samsung TouchWiz based encryption in 2.4 and that works well.
For those interested, the only remaining issues I have with TWRP regarding encryption are that if you want to format /data from TWRP (say, to remove encryption) it will fail unless you _do not_ enter the password at boot, and the TWRP formated /data cannot be re-encrypted (you must use stock recovery to factory reset/wipe the device or else the encryption step will sit deat in the water doing nothing). I suppose the second one is a bug that will be fixed in a later version.
I will check Online Nandroid out anyway, being able to make a backup from a live system sounds good!

I have a similar issue. I had the device encrypted and decided to ROOT (using CF-AutoRoot). Unfortunately I cannot bypass the password screen now, although I know that I'm entering the right password. You are saying that if I flash TWRP everything will be fine?

Two separate things:
Root messing up encrypted touchwiz devices and twrp not handling touchwiz encrypted partitions properly.
The 2nd one, as much as I can tell, is fixed since before 2.5 so if youwork with the latest (2.6) you should be fine.
The first one I haven't played with in a while, but my finding is that you don't want to root a device once it's been encrypted. I've tried several different methods including rooting as you flag as is possible with twrp and all end up the same:the password is not recognised anymore!
The only thing that works for me is rooting before encrypting or only flashing pre-rooted ROMs.

Yes - I had to factory reset the phone and format the SD Card. Never root AFTER encryption :silly:
Disclaimer: I am not responsible for any damage or liability arising out of these steps. I did not invent anything, I just tried something. Only move forward at your risk
If you don't agree ... stop reading and move on...
Background: Our phone has access to so much personal information that its scary if it fell into wrong hands. The only way to fix this is to encrypt phone. I did lot of research and here is a working solution that works for me - try at your risk.
Download Links:
a) Tested with ROM Stock 4.4.4 NH7 Galaxy S4 M919/Jfltetmo by @ShinySide
b) Tested with ROM |ROM|★KANGAKAT★|►KTU84P◄|4.4.4|Xposed|►8◄|6.26.14 by @iB4STiD
c) stock recovery AT&T S4 works with M919
d) Philz/CWM custom recovery
Encrypting with custom rom
1) Assume you are on custom recovery. - Backup everything first. Create a nandroid backup
2) Do a full wipe and install one of the two roms linked above (I have tested with few other roms ... none worked). Start the phone and set it up the way you want. Install all apps etc.
3) ODIN Stock recovery. See #c under download above. Its AT&T stock recovery but works for me. You need to know how to ODIN - find out. Doing this wrong will permanently damage your phone
4) Start your phone and turn on encryption. You will need to set lock type = password and will need to connect to charger and have 80% charge.
- Phone will do blank and stay blank for 20-30 minutes. Do not do anything. Encryption is happening behind the scenes.
- You might have to do this twice or thrice if it did not encrypt first time. For me the phone went blank first time and after 25 minutes it restarted but device was not encrypted. I redid the same steps and worked second time.
- If you interrupt the encryption process (battery pull or power up) you will see error message (encryption failed, reset device)
5) If all goes well you now have a password protected encrypted phone with custom rom!!! Check in Settings -> Security
6) You may install custom recovery ... but I don't see the point because you will need stock recovery to decrypt
To install another ROM
1) Reboot into stock recovery, then wipe data and cache (this removes encryption).
2) install your recovery of choice and install ROM using recovery. Philz/CWM

Tronicus said:
How to Flash a rom on an encrypted Android phone (specifically this one, the I9505 SGH-I337).
The Problem: Once encrypted, you can't decrypt it easily. When encrypting the phone android will tell you you can only decrypt it using a factory reset. Naturally you assume it's talking about the "Factory Data Reset" option found in Settings --> Backup and Reset. But noooo, Android is lying through its ****ing teeth. Then you'll assume you have to wipe everything from your custom recovery mod (CWM, TWRP, or one of those). Wrong again! You'll get beautiful "can't mount /data" messages and more bull****. I read about a workaround that required installing the new rom using ADB, but I had ingeniously disabled USB debugging prior to wiping everything, so I only got so far with that option (plus it's tediously long if you haven't installed all the necessary software already and don't feel like bricking your phone because you made a typo in the command line). So, apparently the only other way to really format that partition free of its encryption is to use a stock recovery. So:
Short Version for Godlike users who know automatically how to do all this **** without any help (mimicking how most help posts are finely detailed on this site): Flash stock recovery, wipe everything, flash your custom recovery and install your new rom.
Long version for us mortals who don't know everything and haven't already downloaded already every single bit of software on earth:
Backup all the stuff you want to save. This process will truly wipe EVERYTHING. You can do it manually, or you can use an app like Titanium Backup Pro to help you (find it on Google Play Store). Here's a nice guide which recommends what to restore and what not to restore: http://forum.xda-developers.com/showthread.php?t=1480343
Flash the stock recovery using Odin. You can download a stock recovery from here: http://forum.xda-developers.com/showpost.php?p=49687791&postcount=3 It's the link called "I337MK2stockrecovery.tar.md5" In case you don't know how to flash it with Odin, this short guide will help: http://forum.xda-developers.com/showthread.php?t=1506697
In step 6 replace "recovery.tar.md5" with the stock recovery you downloaded.
Wipe everything from the Stock recovery console. This little ****er will **** up the encryption all those sissies couldn't touch. You're welcome. You boot into recovery mode from a turned off phone by pressing simultaneously the volume up key + the home key + the power key until you see blue text appearing in the top left corner of your screen.
Reinstall your custom recovery. In my case I had installed the rom BEFORE flashing in the stock recovery (apparently it works, you just can't boot because of the encryption), so I was able to boot into the new rom before I returned to my custom recovery. Weird. Anyways, I recommend CWM. You can pick it up from this link: http://goo.im/devs/philz_touch/CWM_Advanced_Edition/jflte
For some weird reason they call the I337 version the "jflte" version. It's bonkers. Click there, and download the latest version that ends with .tar.md5. This version is upgradable via Odin, which we already used. Use the same instructions used as when you upgraded the stock recovery rom.
Boot into your recovery mod and flash your rom like you usually do.
A word about TWRP: it cost me many hours of work and I don't recommend it. Its website is outdated, and recommends using GooManager (which is no longer mantained) and doesn't work anymore for this. GooManager suggests using a new, different app, which doesn't have the option of installing TWRP. Then I tried using their TWRP Manager app from play store and the image file wouldn't download. Then I tried manually selecting the image file in TWRP manager that I downloaded from their site for use via the ADB method, and it bricked my phone... twice (using two different methods the app sugested). I tried so much because in theory TWRP has the ability to decrypt android's 4.4 encryption, but after looking at their github site I noticed it was filled with people's reports (including people with the S4) on how it wouldn't work decrypting squat. So I gave up, and installed CWM in 30 seconds.

One of the things I needed was the ability to encrypt my phone (device only not external SD) for security purpose. Our phones today gives access to lot of information that I would rather not fall in wrong hands. I did lot of research and here is a working solution.
Credit goes to @Tronicus and his reply Flash a Rom on an Encrypted Android
The quote looks long however it is really very simple. To install another ROM
- Install and reboot into stock recovery, then wipe data and cache (this removes encryption).
- Then install your recovery of choice and install ROM using recovery. Philz/CWM
This has been tested working on |ROM|★KANGAKAT★|►KTU84P◄|4.4.4|Xposed|►8◄|6.26.14 by @iB4STiD
This did NOT work on a Touchwiz ROM by same developer
I have not tested any other ROM

I don't know if it matters too much or not, but the stock recovery you linked to is for the AT&T S4. A good rule of thumb is to never use Odin to flash anything not specifically for your particular device... In this case the M919.

I have tested stock recovery on M919 .. it works
Honestly im surprised its not talked about more since there is a big push for personal privacy when it comes to data. Encryption really is a pain in the ass to work with on android. Figuring out how to switch or update custom roms while encrypted will drive you insane. The easiest way is to just odin back to stock and start over, but that requires a computer anytime you need to flash anything.
I recently was trying out one of the 4.4.4 GPE roms and turned on encryption. It worked great until i started missing touchwiz and wanted to go back to HyperDrive TW. So the journey began...
First of all, i backed up everything to external storage since i knew everything on the internal storage would have to be wiped. I loaded the phone into recovery mode (using TWRP) and tried wiping, but all i got was a bunch of "Failed to mount" errors. Fine. Got the same error when trying to factory reset or wiping /system, /data, /cache, and anything else. Tried formatting to different file systems and then formatting back to the original but no luck. Fixing permissions didnt help. I just kept trying everything available multiple times.
Eventually it started wiping everything except the /data mount. Well... At least i could install new custom roms. Im not sure exactly what did it because i was just throwing everything at it. Anyways I got it to install, and booted into it. Nope.
Now it was saying I needed the password to decrypt the internal storage. It would detect wrong passwords fine, but as soon as i put the correct password in, it would allow me in, show the green android encryption picture, then blank screen. I thought it was just decrypting and setting up my rom but after a few hours my screen was still black and nothing was happening. Pulled battery and went back to TWRP.
I started wiping everything again and again and tried doing everything i could to wipe everything on the internal storage. Again, not sure what did it, but eventually got it all cleaned up and got a new rom installed and could boot into it.
The whole process probably took about 6-7 hours...
I dont even want to enable encryption on the new rom...

Yeah Encryption does not seem to work on TWZ roms. I tried on G Eye without luck.
I have updated op. Please check
Encryption will slow down your phone quite a bit. More battery usage + more CPU usage + slower phone = not worth it unless you've got some very private stuff you don't want being shared. Otherwise, 3rd party apps that lock a lot of files, can encrypt certain files, and hide others will do the trick perfectly well.'
Not trying to bash fully encrypting your phone, but I've tried it before and although I am very pro privacy, I had to eventually take it off due to all the extra hassle it created.
Don't know about slowing down. I am not seeing it. I feel differently about security.
Alright, I'll lay out what happened. My end goal is to just have a rooted tab, but at this point, I'd be willing to just have it back to how it was. Preferably without losing everything on it.
-Looked around on how to root it, and found the following, and use the files it suggested.
- Seemed easy enough, and I had rooted/installed android on my old HP Touchpad, so I dl'd the files, and gave it a shot.
- Couldn't get CWM recovery on it, so I ran verify root and it said it wasn't rooted, even though I has SuperSU. It would even ask to grant apps permission, and I'd grant it.
- I opened SuperSU, and it'd say it needed to update the binaries, but would fail on normal, so I dl'd the newest zip, booted into recovery, and tried to load it like that, but 2 lines would come up red. I think they were just verifying signatures, so I ignored it and let it reboot.
- I opened SuperSU again, and it still said it needed the binaries updated, failed on normal attempt. I decided to try again from scratch, unrooting it and all. So, I went into the SuperSU settings and did it's thing, but it still had the version of SuperSU that initially was on it (it wouldn't let me past the "update binaries" prompt).
- I found that I needed to use Odin to flash a stock firmware back on it, and dl'd both version here.
- I tried the first one, and then it wouldn't get past the "Samsung" screen (the 2nd one with just the word Samsung, if it matters).
- I can still boot into Odin and Recovery, thankfully, so I tried the 2nd stock firmware. Same issue.
- Finally, I tried the rooting process again, hoping to get it to boot, same thing. So, I tried the 2nd stock firmware again, praying something good would happen, and still stuck on the Samsung screen.
I can still boot into Odin and recovery, but I have no idea where to go from here. I still want it rooted if possible, and I'd prefer not to lose all my games and such. I just found "[ROOT][RECOVERY] [ALL IN ONE] Cf-Autoroot-twrp-T800-T805-T-700-T705" thread here, but I didn't want to try it just yet.
It's a SM-T800. I had Lollipop on it. Don't know much else to add, but please help!
Thanks all.

Well... you said you just updated to lollipop, but in order to not stay stuck at splash screen, you have to factory reset. I saw that you don't want to lose your games and such so you probably only have one option. That option is to flash twrp and make a nandroid of your data. Simply boot into download mode, download the twrp .tar http://twrp.me/devices/samsunggalaxytabs105.html
And now go into Odin, untick autoreboot, now hit the pda/AP button and pick the twrp tar. Hit start and let it do its thing. Now after its done flashing, your gonna have to force reboot. Simply hold power+volume up and down+home button all at the same time. Wait a bit and when the screen turns black, quickly press power+volume up+ home buttons all at the same time and it should boot into twrp.
Now in twrp, hit backup and hit backup data. Hopefully that should save your apps installed. Now after its done, go into wipe and silde factory reset. It should remove installed apps from Google play store and it won't remove pictures and such. It just removes the apps you installed. Then now reboot and wait....
Hopefully this helped

As said you will have to factory reset, this will wipe data and cache.
You can use the link you posted above to install TWRP and root.

Lollipop changes the data partition so even if you back it up and then restore it with twrp In kitkat it likely won't boot afterwards.
All you can do is wipe it and take the hit.
Alright, I have TWRP running. The size of my "data" is just over 16 gig, and my space on the sdcard is 14.9 gig, so I've been trying to delete data to knock it down. I still have 1.3 gig to go. Everything I'm deleting, in the data folder, is barely making an impact.
I see what you're saying that I probably won't be able to restore it and have it work, but I still will try. I can always factory reset it again later. Once I wipe it, though, and update back to lollipop, couldn't I restore that data backup?
I gotta take a break and knock out some real work, lol, then I'll continue, and update here. If nothing else, maybe it'll help some other poor soul like me in the future!
Once I have it booting all the way again, do I just use TWRP to install SuperSU and it's rooted? Thanks again. I appreciate it!
Not sure what youre trying to do here. Just wipe the data partition with twrp,

Ashyx, I was just trying to save my game data, while ending up with a rooted tab. And you were right, of course! I tried to restore the back up to no avail, haha....well, I wiped it again, and it booted up just fine, and it is rooted to boot. I can't believe it was that easy with TWRP to root it.
I'm betting this isn't going to work out, but is there anyway to extract my game data from that backup I made, and transfer just that back to my tablet? If it is possible, it'll probably be beyond my ability, I bet, but I'm just curious.
One other question. With TWRP, can I get Lollipop back on it? Or do I need something else on it first?
Now, it's off to figure out how to get my Impulse Controller to work with it so I can play my games with it!
Thanks for helping me out, regardless. I truly thought I had bricked my $600 tablet. My wife would've killed me for wasting that much money, lol!
There is an app called nandroid manager that will allow you to extract data from nandroids, you could extract your game data with that.
The better way would be to make a system and data backup of your current system, reflash lollipop then restore your lollipop data backup. Then back up your game data with titanium backup.
Restore your kitkat backup then restore your game data with tb.
Hey guys,
I really need help. I was about to update my brother op3 from 3.2.4 to 3.2.8. When I was done I wanted to continue to flash to 4.0 but when I use the advanced reboot to boot into recovery it suddenly said "factory reset"!!!! Everything is gone even from the storage! I cant even backup from the backup file from twrp because it is gone! Can anyone please help me out? There are software to recovery this but I have to pay for all of them and they are not cheap!
Thank you in advance!
After a factory reset, even paid recovery tools aren't able to fully restore your data to their original state. At best, you'll get back a majority of the individual files you had on your phone prior to the wipe. The more you use the phone after wiping it, the more the old data is overwritten. At this point, I would just make the best out of this unfortunate event and clean flash whatever OS you were trying to update to. At least the phone will be de-cluttered at this point. You may even notice that the phone feels a little faster afterwards, and may even improve your battery life slightly.
If you had something really important on your phone that wasn't backed up, data recovery tools may be able to restore it, but I wouldn't hold my breath. Additionally, TWRP backups do not backup media files such as music, photos, personal documents, etc. Even if you were able to find a nandroid backup, you would only get back your OS, apps, and app data. Most of this can be restored by just downloading everything again.
In the future, I would recommend saving nandroid backups directly to a USB flash drive through USB OTG. Music and photos can also be backed up to the cloud through various free or paid services (Google Photos for example).

Chance to recover your files are verry slim. Use the TWRP provided by Bluspark, it's on his main thread, stock twrp seems to have many issues.
