[Q] Bootloop after flashing stock ROM via Odin. I think I've tried everything. - Samsung Galaxy Core

The Wifi on my phone wasn't turning on, even after factory reset, so I reflashed stock ROM via Odin (v3.07)
I got stuck in a bootloop, and after factory reset via the stock recovery + wipe of cache partition, it was still stuck.
I then re-flashed the stock ROM. Still stuck.
Tried using Kies 3, with the firmware upgrade and installation tab. Said something about not supporting my phone when I was prompted to plug it in. (SM-G355H; Samsung Galaxy Core II Duos)
I then found an unofficial version of CWM v6 for my phone (there's no official support), and quickly flashed that (via Odin 3.09; which is what I use from this point on), forgetting that my phone was no longer rooted. I wiped davlik cache and data. Still stuck. Then I rooted my phone. Stuck.
Then I reflashed stock ROM (this time, I downloaded from another website) (to test my luck, I tried seeing if simply a factory reset and cache wipe would work. It did not) rooted my phone, and flashed CWM. Wiped davlik cache. Still stuck.
By the way, when I wipe davlik cache it says:
Warning: no file_contexts
E:unknown volume for path [/sd-ext]
Davlik Cache wiped.
Any ideas on what to do now? I can't send it to a manufacturer / repair store where I live. I'm thinking maybe I should untick Auto Reboot and/or F. Reset Time when flashing, use an earlier version of Odin or the ROM itself, or maybe there is something I can do with ADB? I'm not very familiar with it, but I'm more than willing to learn. I just need some direction...

Update: Flashed with Auto Reboot unticked. Still in bootloop.
Flashed with same ROM, different country. Still in bootloop.
Alright, I fixed it by using Kies, via firmware upgrade and installation. You have to ignore where it says that your device is not supported, and just leave it to download. If you get stuck on the setup screen like I did, try cache wipe + factory reset. If it doesn't work flash an earlier version of the firmware. You might be using the wrong region (It's not always your country), use Kies to check. When it tells you what pda/ modem / csc it wants to update the region will be in parentheses ( eg ACR). Use all of them possible

[Q] Can't get rid of encryption

I'm really stuck and need some help here, thanks in advance. So basically about a month ago I encrypted my rocket to use on my company's Exchange, but it turns out they don't support Android so that was a waste. At the time I was running Stock ROM ICS (Rogers), before then I had dabbled with Paranoid and a few others. I had CWD 5.5 installed.
Yesterday I was eager to try the new 4.1.2 JB leak, so I flashed it through CWD and all went well.. until it booted. It stops me just as it loads and gives me the message "Enter encryption key to unlock storage". It's been a while so I couldn't remember my PW, so I tried 100x until it said wiping data. I figured maybe it worked the same way as Blackberry, but even still after wiping it wanted the password and now when I enter anything in, it just reboots the phone.
Getting nowhere I went back into CWD, reset to factory default, wiped the caches etc, formatted system/data, and then reinstalled Stock ROM 4.0.(Rogers) using ODIN. That booted OK so I figured I managed to rid of the encryption, so again I installed CWD, and then the leaked 4.1.2 but again it's still giving me the same message!!! Arg! I've wiped all the caches a million times, formatted the system and data, reset factory defaults 10x, I've even tried flashing 4.1.2 Leak using TWRP but still no luck. I'm assuming I'm getting that message because it's still encrypted, so how the heck do I rid of this encryption? I'm thinking I have to re-partition the internal SD? Please help, I'm eager to try the new 4.1.2. Thanks
No amount of wiping /system, /data, or /cache will remove the encryption settings/keys because they are not stored in any of those partitions. They are stored in a partition that is not accessible by 'ordinary means'.
Did you perform the factory reset in CWM or in the stock recovery? I would suggest to use ODIN to flash back to the stock ICS ROM and recovery, boot to the stock recovery, factory reset from there, then reboot and make sure that encryption is no longer enabled in settings in the stock ROM.
If that's all good, then use ODIN to flash CWM and use it to flash a custom ROM.
Some info on Android encryption
Still no luck! arrg!! So I first used ODIN and install the Stock 2.3 Rogers ROM, I went into settings and reset back to factory. I rebooted, and went into the Stock Recovery however Up down arrow's worked but the enter "power button" wasn't working, so it doesn't look like i could choose reset factory from within stock recovery. Anyways, I rebooted into Download mode, used ODIN to install the STOCK 4.04 Rogers ROM, and rebooted. I checked the settings and it looked like encryption was off, or at least it had the option to encrypt. All signs anyways looked like it was off. I then installed TWRP 2.2, upgraded to 2.3, then flashed the leaked 4.1.2. And again when I rebooted, after the ATT logo I'm presented with the "Enter password to use encrypted device storage". I'm guessing it's still encrypted? And why is the stock google leaked 4.1.2 asking for the password but not the Rogers stock 4.04 ROM? Anything else I can try? It's also strange that when I enter the stock recovery mode the power button isn't funtioning as the enter key. Up down enter keys work, also if I press the home button, or maybe it was the back button it reboots. Thanks for the replies, hopefully there's more I can try. Maybe re-partitioning the entire internal SD?
Success... but lost cell unlock.
So after another Stock ICS Rogers ROM install, I went into backup and reset and did a factory reset. There's an option to delete the USB as well, which I may have been skipping... but I checked it off this time, then rebooted into the Recovery mode using TWRP 2.3. This time around I also made a few changes. I used the 4.1.2 debloat, but there's an option in TWRP to format the Android Secur... which I did... just because I wanted to nuke everything. So now yaahh!!! 4.1.2 boots up and no more encryption issues. Bad news, my phone is no longer unlocked
Idea's on the unlock?
NM... looks like using the debloat 4.1.2 I forgot to toss in the Radio, because using the regular 4.1.2 I tried again it works good. That'll be the last time I ever touch encryption.
To delete encrypted partitions successfully you need to install the android version which at least supports encryption. For example, if you install android 2.3 and you do a factory reset won't work for the internal sdcard, but probably will if you install android 4.1.2.

Tried to inställning CM - stuck at boot (n8020)

Hi. Yesterday I succesdfully rooted my n8020 (galaxy note 10.1 LTE Swedish). Tho, when I tried to flash Sbiddens modded CM version, it failed. I wiped data/facto ry reset from CWM, wiped cache and Dalvik. Flashed CM and Gapps. Rebooted, only to get stuck at the blue-ring Cyanogenmod boot screen. Tried to redo all the steps in different orders, no succcess. Stillvstuck at boot.
Then came the puzzling part. I downloaded the original firmware from sammobile.com, and flashed it via Odin. It succeeded, bit whenbit booted in back to the standard rom, all my applications and all the data was intact! As I sevetal times wiped data/factory reset, I assumed thatevwrything would be gonw and that I'd have to install everythingnfrom scratch. Am I correct in assuming this, and may this be related to CM getting stuck at boot? Any hel greatly appreciated!

I have seen something similar when I installed Cyanogenmod on a kindle fire, I had to do a factory reset after restoring back to stock firmware.
I would suggest that you try doing a factory reset after restoring factory firmware on your GNote.
Success with Philz recovery
Had the same problem loading onto my N8020.
In the end I used a different recovery and it worked first go.
Try using Phils recovery http://forum.xda-developers.com/showthread.php?t=2202714

[Q] Phone stuck "Optimizing apps" after upgrading rom

Long time visitor, first time poster.
Upgraded rom today when I found of there was an official 4.3 upgrade for the Verizon GS3. Looked around and found this one: http://forum.xda-developers.com/showthread.php?t=2600305 Before that, I was on the last official stock, flashed deodexed rom.
Installed rom zip via CWM, rebooted. After loading screen, it starts upgrading apps. It got stuck on 82 of 601. After 15 minutes, I booted into recovery and wiped cache (failed to do this during initial install, it never was a problem before). Reboot, gets stuck on 93 of 465. Hard reboot, total number keeps going down, but keeps sticking.
After several hard reboots (pulling the battery), I got it down to 1 of 1, but it won't go any further. It's been about an hour.
What do I do next?
While waiting for ideas, I'll hard reset, boot into recovery, wipe cache again, and see what happens.
Edit: Wiped cache partition from CWM, rebooted, still stuck at 1 of 1.

I believe you may need to use ODIN to manualy re-flash the 4.3 update. NOTE: This will lock your bootloader, but seeing as how you have already upgraded it already is.

Do I specifically need to find a rom that is Odin flashable, or should I try another zipped package flashed through recovery?

Don't use Odin to flash the official tar file, you'll lock your bootloader and you'll be stuck.
Wiping dalvik cache should work, but if it doesn't then do this.
In recovery factory reset, wipe cache, wipe dalvik cache, format system, then format internal sd card (this will erase everything on your phone). Then reflash the rom again.

I wanted to try something else before formatting the card and having to deal with that, so I downloaded the zipped rom here http://forum.xda-developers.com/showthread.php?t=2591895
From CWM I wiped cache (again), wiped dalvik (again), and installed rom. On reboot, went through app optimization without any problems.
I'm not sure what the problem was, but I fixed it by using a different rom.
Thank you for the help.

"Encryption Failed" - Phone Will Not Factory Reset

After searching through countless threads on this site, I've had no avail in resetting my Rogers Samsung Galaxy S6 running XtreStoLite 2.2.
A little while ago, I thought it would be a good idea to encrypt my phone with a custom ROM installed. I knew I had recovery and download mode, so I thought It'd be no biggie. Left the phone on overnight encrypting, came back 24 hours later and knew that it hung somewhere. Booted it up and this screen came up: Reset it and restored from TWRP backup, the same screen right here came up: http ://i.imgur.com/J37aZaq .png (sorry XDA will not let me post links, remove spaces) after this, I tried pressing the "reset device" button without success. It just rebooted the phone. Tried to restore from a different backup, no avail, then I tried to flash my custom ROM again through TWRP, no avail. I download ODIN and flashed stock Samsung firmware onto it and it still gave me this screen when I was done. Tried going into TWRP and factory resetting (where it wipes all partitions) and nothing happened. Currently, I'm trying to flash my Samsung Galaxy S6 with the stock firmware through ODIN with the "re-parition" box checked.
It seems there's a hardware flag of some sort stopping this from working. I mean, my file system is brand new, reset to factory defaults, I even checked with ADB and everything has been formatted. Checked with TWRP file manager and everything is good. But I can't get past the "Encryption Failed" screen.
Help me! Thanks.
fix
did you fix this?
Hi, i am encountering the same problem with my G920F.
I have the XtreStoLite_Deo_Mod_v.2.3 and also TWRP installed
I started encrypting but it got stuck so i rebooted my phone and got the same message (Encryption failed, please do a factory reset). So i did the reset but the same screen appeared. I also tried restoring from a back-up from TWRP but the same screen was still there. So i decided to do a full wipe and restore the phone with a twrp back up witch was on my laptop. But when i am in TWRP i can not copy files to (or from) my phone. So it is not possible to get the backup on my phone. I am able to get in to download mode and connect the phone with odin.
My questions are :
- what was the solution to the problem?
- What causes the copying error? And what is the solution? So i can put the backup on my phone and try to restore it this way.
- What are my option with odin? Can i use the TWRP files in odin?
Thanks a lot in advance
Jules
Solved the issue. After a full wipe i installed a stock firmware with odin. It still displayed encryption failed after reboot. But after the factory reset the notification was gone.
I have fixed this
Best solution is on a stock rom to reset. If rooted with recovery -format and wipe all data, reset, let sit at boot for a while, go into recovery and install new rom from USB-OTG, or odin from download mode.

Samsung Galaxy fit S5670 stuck after flashing

I have an old Samsung 5670 and decided to flash cyanogen 11. I successfully installed clockwork 6.0.4.5-beni and then i flashed cm-11-20140116-NIGHTLY-beni, wipe data, wiped cache and dalvik and everything worked just fine. And then, dissaster came: i tried to install gapps and since then (i got a message that flashing was successful) and since then, everytime i turn on my phone i can only enter into the os but the only thing i see is battery status and time on the upper right corner and the rest of the screen is black. I can swipe from the top (i can see the date and time and a "emergency calls only" message).
I tried wipe data/factory reset from recovery, wiped cache and dalvik, i even re-flashed cm 11 and i am still having the same issue. I tried to flash a different rom (miui 2.4.20) but im getting an "installation aborted" message. Even tried to flash the stock rom with odin but though i have installed the usb drivers odin can not "see" my device.
And yes, i was stupid enough not to take a nandroid backup
So now what? Is there a way to fix this?
