Getting Failed to clear BCB message: failed to open /dev/block/boot/device/by-name/misc: No such file or directory after phone crash​
please help

I have no idea it helps, I had my phone crash on me and me trying my old-and-tried flashing etc. I did not have such BCB message, but it sounds like there is an issue with the partitions or partitioning.
There are nice YouTube videos at least that show how to flash the stock ROM (not giving link here for advertising etc).
it boils down to (FIRST get your data off the phone as you are going to lose this)
- TWRP being bootable
- in TWRP: factory reset, wipe data
- flash stock ROM twice: to partition A and after reboot to TWRP, to partition B. I do not know why this needs to be done, love to learn it by myself.
- flash without wiping a custom recovery if wanted.
- restore your data

Mi3 Processes/Apps stopping and Can't erase data in phone

Hi Guys! Im from the Philippines. I have Mi3 bought from SG last June 2014. Last Tuesday, the phone suddenly had a problem when I wake up in the morning.
ROM version 23 (stable), Rooted.
Problems below:
Processes/app that stop during standy (Phone On, no apps running)
android.process.acore
settings
com.google.process.gapps
music
google play services
launcher
When opening Camera, error is flagged "can't connect to camera"
Messaging app stops (default messaging app)
When trying to restore factory default (erase all app, data, etc) phone resets but apps/data
are still there.
Can't erase any data in the phone.
Can't put data to phone (example: Picture from pc to phone). When I tried to copy data to
phone, window pop-up saying the device was disconnected or stopped working.
I can read/copy any data from the phone. (example: copy picture from phone to PC)
Tried to go to mi-recovery and tried the ff:
Wipe cache - ok
Wipe used data - failed
Wipe all data - ok - but when the phone restarted, data is still there.
Wipe sd card - ok
I can't flash rom to phone via recovery since I dont have update.zip on my phone.
Again, when the phone restarted, data is still there and the problem is there.
Tried to flash phone via fastboot using MiFlash 2014.05.09, the results are below:
ROM version: cancro_images_KXDCNBF24.0_4.4_cn_1fbb634ef8 and cancro_images_JXDCNBD14.0_4.3_bb5096bfd9
Using flash_all_except_data_storage.bat
- operation completed. but when phone restarted, the problem and data are still there.
Using flash_all.bat
- operation stopped with Unspecified error0x8000405: FAILED (remote: failed to erase partition)
Additional info:
I still can make calls in my phone. FM radio is working. Music player is working.
Question:
What's next? anything I can do to fix this?
Thanks.

Install CWM recovery first then do the below things from recovery,
1) Wipe data/factory reset
2) Wipe cache
3) Wipe dalvik cache
4) Format system 1 and system 2 from mounts and storage menu
5) format data
6) Power off the device and go to fastboot mode
7) Try to install Fastboot rom again with the option 'flash_all_except_data_storage.bat' using mi flash tool
it should works.
Hello sujithar37. Thanks for the response. What CWM recovery should I install? And how can I install it? I tried to install CWM_recovery_r7_cancro_final.zip using RayGlobe tools but when I tried to reboot the phone it boot loop. Am I doing anything wrong? Thanks.

I have the same problem.
If I try to flash cancro_images_4.11.14_4.4_cn with flash_all, after about 63 seconds I get this message:
(Unspecified error(0x800004005: FAILED (remote: failed to erase partition)..
I believe it fails on the fastboot %* flash userdata %~dp0images\userdata.img command
I can adb boot a recovery image, but any wipes/cleans/ etc say they work, but do nothing. My clockworkmod log shows:
I:Can't partition non-vfat: datamedia
I:Can't format unknown volume: /external_sd
I:Can't format unknown volume: /emmc
I was able to use adb pull and get photos off, but when I try to write an update.zip with adb push update.zip /sdcard/ I get a message saying that I don't have permission to do so.
Is this perhaps a permission issue?

[HELP NEEDED] TRWP + Recovery - Partition Corruption???

Hi all,
I used the SRK Tool recently to TWRP and Root.
All was going well until I used hisuite to restore my phone.
It failed in restoring one app and it created a cache file in data/data, tried deleting the file in ES File Explorer, SD Maid to no avail.
So I went to format the partitions in TWRP.
The phone won't start (im guessing there is no OS so I am looking for the stock rom as the hisuite recovery doesnt work as well.)
TRWP Factory Reset is still showing the same following error
Updating partition details...
Error opening: '/data/data/renamedeleteapp/app_xwalkcore/Default/Cache/5de9a45e57c756c2_0' (No such file or directory)
...done
Click to expand...
Click to collapse
Anyone able to shed some light on how I can fix this corrupted partition and reload an OS so my phone works again?
Thanks!!!
the huawei erecovery system doesnt seem to be working either.
Nor does the hisuite recovery. Asking me to bring it to the service center
Managed to flash the new world ROM but the partition error still persisting. Anyone?
I would say probably your best bet is to use the stock rom here ... http://forum.xda-developers.com/p9/development/stock-rom-dload-file-p9-eva-l09-b136-t3382818 to restore completely to stock and then start again from scratch

[CLOSED]Vivo XL2 TWRP 3.0 and Root

I must note: I use linux. I only used Windows because SPFT Linux version gave me a chip mismatch error I couldn't fix easily.
1: Please read. It explains what problems might arise. Especially post #6 and #13.
2: There are 2 versions of the scatter file. The MT6735 version is what I used successfully. The MT6737Tmod version is what comes from post #6 & #13.
3: Please use each scatter file to Readback your boot and recovery partitions first, renaming as fit, so you can have a backup BEFORE ANYTHING. Then test unpacking them to see if everything went correctly. Then readback every partition in the scatter file so you don't have to depend on the stock ROM for a backup. I didn't and it led me to take this route.
3: Seem to be a difference in the naming of the scatter file and sizes of system, cache, and userdata inside from the stock ROM and what works..
4: DO NOT choose Format+Download until you know which scatter file works, unless you want to chance a Hard Brick.
5: Wiping the dalvik and cache in stock recovery before flashing TWRP seems to be the best thing to do to avoid boot loops or a hung boot.
THIS ROOT PROCESS WAS DONE OVER THREE DAYS OF CAR WORK, DRIVING, FAMILY, AND COMPUTER WORK. MOST OF THE TIME SPENT WAS THIS MORNING TRYING TO GO TO SLEEP. DIDN'T HAVE TIME TO DOCUMENT AND TAKE PICTURES. THIS WRITE-UP IS FROM WHAT I REMEMBER DURING THIS PROCESS. IF I CAN REMEMBER SOME VAGUE DETAIL THAT YOU NEED, GOOD. IF NOT, DON'T STRESS ME. THE HARD PART IS DONE. A GOOGLE SEARCH OF SOME OF THESE PROGRAMS WILL GET QUICKER RESULTS IF YOU DON'T HAVE THEM. THE MAIN THING NEEDED FROM MY RESEARCH WAS THE SCATTER FILE. LINKS FOR SCATTER FILE AND RECOVERY IMAGE ARE BELOW.
Looking for a way to root first day getting this phone in February. Read this post last Tuesday about MT67xx rooting, thanks lsemprini. Spent two days finding which versions of the programs work with this phone, already had the ROMs, drivers, and tools. Dove right in.
I downloaded the ROM from needrom. Scatter file was unusable. Wrong chip error. Phone reads MT6735 scatter file read MT6737. Did a manual diff. Used SP Flash Tool v5.1524 to flash, formatted instead of downloading by mistake, cord got pulled, Hard brick. Fought with Windows7 to get drivers to recognize a hard brick. Still don't know how I did it but it read then flashed. Looked like another hard brick but SPFT would recognize it for the Memory Test. I just held power+vol_down with just charging block power to get it to come on. Sometimes just one of the buttons was enough to get it to power on and start a bootloop. Took two minutes sometimes. Flashing the wrong recovery led to bootloops. Starting SP Flash Tool and plugging in the USB to the phone as soon as it powers off during a loop will let the preloader "register" and the images to be flashed. Flashing from a stock ROM will lead to IMEI being erased. Used SN Write Tool v1.1716 to write the IMEI numbers. Got them from the side of the box. The MD1_DB and AP_DB files needed are in the stock rom.
Ported TWRP, credit to jemmini for the post https://forum.xda-developers.com/vivo-xl/development/recovery-t3311601. Used that recovery as a base. Ported according to the myriad of guides that I have been reading over the past few days. None of them worked as instructed, had to modify trial and error style. Finally got TWRP to read the internal partitions AND remain after a reboot. A lot was going on when I did this. Not sure if I formatted before, I remember flashing a lot of because of something. I mounted the system just in case & flashed SuperSu from chainfire's website, no formatting afterwards. Rebooted and installed SuperUser and BusyBox. I tried adb and fastboot. They work but not for everything. Hooked phone up to computer with debugging enabled.
Code:
adb root
gives a shell, no errors unlike before. Edit: ADB won't let me start as root anymore.

When i connect the device after clicking download, it says "CHIP TYPE NOT match!"
mind you the device is off, i tried to troubleshoot but still getting the same error.
any help would be appreciated
UPDATE: Im thinking it has to be the scatter file, but im not sure.
UPDATE: I got it to work, after flashing superSU, my phone wont boot past the initial white Blu start screen.

Try powering it off, booting to recovery and then wiping dalvik and cache.
The longest it took to get past that logo was 15 minutes. It is either encrypting or decrypting. Didn't get any type of messages until after root, and those were optimizing messages. Only one came through before rooting when I interrupted the boot process and that was about encrypting the phone. Phone was encrypted before root, now it is decrypted. Could have something to do with that. Try wiping the cache and dalvik after flashing. I actually flashed it three times in a row. The third was after mounting storage then flashing the SuperSu zip. Once you see the next logo with the colorful circles and hear the sound it might be another wait. That is where it let me know it was optimizing.
I must note: Please use scatter file to Readback your partitions so you can have a backup BEFORE ANYTHING. I didn't and it led me to take this route.

Good. I had to name it that because of the chip mismatch error. It was from the V7 ROM. The other two are updates. I also messed up big time along the way. My phone always read MT6735 but it does have MT6737T in different files. I always wondered about that. I got it to work without buying another phone.
It seem that the phone boot logo never goes away. What should I do now?

Hope you Readback your original recovery and other partitions. I didn't and worked hard to get it back. When I just flashed the recovery and something went wrong, it reverted back to the stock recovery.
Try doing this:
1. Start SPFT with the reçovery you want to flash.
2. Hold down the power button. AS SOON AS IT VIBRATES, PLUG THE USB CORD IN.
3. Hopefully you timed it right and it will flash and boot.
Sometimes it took 15 minutes to get past the boot logo.
Here what I did so far
1. Format using SP Flash Tool
2. Download /// By Using Scatter-Loading Files (MT6737T_Android_scatter.txt {From Rom}) Which it check all the boxes AUTO ///// It works but I didn't change the recovery.img like TWRP.img
Download it
It works normal.
___________________________________
But I want TRWP.img to be my recovery for root (SuperSU)
I try SP Flash Tool to change the recovery img to TRWP.img /// Using Scatter-Loading Files (MT6737T_Android_scatter.txt {From Rom}) I UNCHECK ALL BUT RECOVERY.IMG
Before this happen I didn't factory reset or Format anything yet.
It work to Recovery.img but THE BLU LOGO IS STILL LONG
I feel like it not working

Try flashing stock ROM, wipe data in stock recovery, then flashing TWRP, wipe dalvik.
If that don't work, wipe data then flash stock ROM with TWRP recovery, wipe dalvik.
The scatter file from the stock ROM gave me problems. Had to modify mine.
Don't forget to restore your IMEI afterwards since you formatted+flashed.
I will try

The one I attatched on the first post #1 is my modified scatter file. The mods included changing the size to the system, cache, and userdata. Just compared all three. The stock MT6737T scatter file and the V12 ota scatter are the same. The one I changed, MT6735, have the file name, platform name, and partition changes. I don't know why I had to modify it., especially the size parts. It all worked when I did that. I basically gave up on it because of a hard brick. Then I remembered reading MT6735 in some file a few months back while roaming the file system. Made the changes and was back in business. Maybe you need the stock scatter file, here it is.
It's what the end result of this post @ANJIII did minus the size changes..
He just did the name changes and it worked for him. Ya'll seem 180° from where I was.
The second one is from the V12 OTA update. It is very minimal, must be all that is needed for a scatter file. Not really sure tho. Hope it is just scatter file issues.
As long as SPFT is reading your phone, it's still a chance on it all working out. That is how I viewed it.
@andromedaXVIII Don't know if you got it working. This might be a potential solution.

I take it TWRP flashed successfully, it is having a problem reading those four partitons. Possibly encryption is stopping you. Try flashing this in TWRP before anything else to remove the encryption.
I didn't get any errors. I know the userdata partition was different in the scatter files. That could be the reason for /sdcard not being recognized. Must be a difference in the layout of phones, not really sure. My protect_s, protect_f, and nvdata partitions and /sdcard all mount fine, pictures attached. I am able to do a backup in TWRP. I have been playing around with porting different ROMs and came across an issue similar to this. Had to change some lines in updater-script.
I checked fstab.mt6735 file in the stock recovery, the modded twrp3 recovery, and stock boot recovery to make sure I didn't make any typos or leave anything out. They all have the same lines. Had to do this:
Code:
("ext4", "EMMC", "/dev/block/mmcblk0p5", "/system")
in the updater-script I was working on. I got ahead of myself flashing a ROM and was stuck on the 1st logo screen. Held power+vol_down to get it unstuck. Yes I was all calling myself kind of names like I'm sure some people have done following this guide.
Which scatter file you used? Did you do a readback in SPFT with the WORKING scatter file and mount one of those images to check if you can read and write the files. I mounted system.img from the stock ROM to make sure I could read and write the files before I started with flashing. I'm thinking there is are internal differences in the XL2s. You might have to reflash using the stock ROM with TWRP as the recovery with the Format+Download option since you got TWRP installed.
Once I get through playing around with trying to flash this ROM, I will restore and try to find all the partition mappings and update TWRP to work with the format from the updater-script and see if that work. Will let you know what happened.

can you send us your vivo xl2 specs because there are two versions of xl2, V0070UU and V0070EE. Mine is V0070UU. I just did some renaming and editing in the scatter file of MT6735 and it bootloop once after I installed the twrp. I restarted my phone during the bootloop by holding the power button. After that, I opened the twrp to install the supersu then wipe dalvic cache. You may now boot up the phone and it took 10-15mins to use it because the system shows that it optimizes 205 apps(in my case, maybe because I have installed numerous apps). After that my phone is usefull again and I installed V4A because that's the only reason why I wanted to root this phone.
Here is all the information I have pulled so far from the phone. Have a screenshot attached from About device in settings. The attached zip file is all the information I could think to pull using adb . The attached file is my partitionlayout. I just ran cat against every file to see what it would give me and redirected the output. Using adb while the phone is in recovery let me pull and read the files I couldn't while the phone was booted.
@Alexis96312, try to run this command in terminal to get your partition map:
Code:
adb shell "su -c 'ls -l /dev/block/platform/mtk-msdc.0/11230000.msdc0/by-name/'" > someFileName.txt
I have mine listed in the zip file as partitionLayout.txt It will list which names go to what device in /dev and save it in your current directory. The file can be used to get the correct partition layout on your phone. Post the results and I will repack the recovery to see if it will work for you. You can do it also with Carliv Image Kitchen, it has a menu :good:. You will have to modify the fstab files in the ramdisk folder of the extracted image to what the partition map specifies. I went thru all of them to be sure when I first ported TWRP.
@ANJIII is correct about the different versions, nice catch. I forgot about that. I assumed you had the V0070UU version like mine, fault on me for not asking. Mine specifically says BLU_V0070UU_V07_GENERIC 25-11-2016 09:46. I'm thinking the GENERIC part comes from me having to flash the stock ROM. I think it had BLU_V0070UU_V07 with user/keys before I bricked it and had to flash the stock ROM. Got three extra apps that I instantly removed. Seems like the stock ROM function the same as before bricking flashing stock.

It look like the pid:vid aren't recognized correctly. Usually a reboot will help.
Are you connect using adb while in recovery? If so, see if Windows will install new drivers for you. My Linux box read mine as a Samsung at one point. Try running the ls part of the command in TWRP terminal.
This is where I fought with windows when the cord got pulled during flashing. I never got an error like the 2 at the top, always like the bottom one. I kept adding legacy hardware in device manager until one of them worked. The Linux version of SPFT always give a chip mismatch error. Wish it worked so I won't have to boot to Windows.
I kept doing format+download and and plugging the phone in until Windows recognized it because it was in a bootloop when that happened. You need the preloader to be recognized.
Both stock ROMs are on needrom.com. I downloaded the UU version, the EE version is what you might need. I'll pm you a link to my backups from TWRP to see if they will work for you. Same thing happened to me playing with the new ROM. Restoring my boot and system got it back working.

Advanced advice for internal storage recovery after attempted flash to LineageOS 17

Hi everyone. Got a puzzle for you forensic data recovery guys out there. I am a fool having a bad day today. For the first time in 10 years of screwing with Android, I backed up my ROM with twrp and also backed up my sms and calls, but then managed to somehow forget to copy those files off the internal storage before trying to flash my phone to LineageOS and botching the internal storage. Here is what happened.
0) Before state: Rooted (I think) and for sure running OxygenOS 5.0.3, flashed via TWRP. TWRP version 3.2.1-0. 128 GB OnePlus 3T
1) Backed up System, data, etc to backup on internal storage via TWRP. Booted into OS and backed up SMS and calls to .xml file.
2) Wiped data, system, cache and dalvik/art cache.
3) Downloaded LineageOS w/ microG via zip in TWRP and attempted to install. Received error that I needed to update the modem to at least 9.0.3.
4) Mounted storage from TWRP and copied in Stable9.0.3+Firmware+Modem_OnePlus+3T.zip. Ran the install and was successful.
5) Installed lineage-17.1-20200826-microG-oneplus3.zip via TWRP. Left prompt to install TWRP checked and booted into OS.
6) Upon boot, saw the message: "Decryption unsuccessful" The password that you entered is correct but unfortunately your data is corrupt.
7) Rebooted back into TWRP to mount storage. Could not get anything to mount because it would not accept my decrypt passcode.
8) Figured TWRP bug, flashed twrp-3.4.0-0-oneplus3.img via fastboot. Could decrypt now with passcode but all storage read 0MB
9) Flashed modem back to OnePlus3T_5.0.3-25-05-18-FIRMWARE-flashable.zip via adb sideload method which is what I assume I was running before since that was the OS version. Rebooted
10) Booted back into TWRP, discovered I still couldn't see files. Downgraded TWRP back to 3.2.1-0 via fastboot.
11) Unable to decrypt from TWRP or even install zips. No change at any point in the OS. Flashed TWRP back to 3.4.0.0.
12) Ran adb shell twrp decrypt XXXXXX (where XXXXXX is my pin) which gave me this message:
Attempting to decrypt data partition or user data via command line.
(then it returned to shell so I assume it worked)
13) Ran an ADB pull command (adb pull /dev/block/dm-0 backup.img). There is obviously something there because it downloaded 111 GB worth of .img file (which I'm 99% certain was the amount of space I had used on the phone). Tried to open the .img file with multiple EXT4 programs and they all said the file/partition was corrupt.
14) Tried to wipe data via TWRP. Failed to wipe because it couldn't be mounted. Followed this:
https://************/how-to-fix-twrp-unable-to-mount-storage-internal-storage-0mb/
15) Ended up with MTP mount of 101 GB free space. Everything seems to be lost on the phone at present. No programs I use to recover the data off the MTP mount (just doing a raw file scrape) can see it as a OnePlus in Windows.
After finding a better guide on XDA, it sounds like this is a known issue that happens when you go from 5.0.x to 9.x on this phone where your encryption breaks and you lose all files. Unfortunately I saw that about 15 minutes after step 14...
My next thoughts would be to:
a) downgrade everything (ROM, firmware, etc) and then try to push the 111 GB .img file back to the phone via ADB, then flash a stock OnePlus 5.0.3 ROM over it to see if I could get the internal storage to mount again. Don't even need to boot into the OS--just to get the internal storage mounted again through TWRP.
--OR--
b) convert the .img file to a .raw and then possibly a .vhd and use Recuva or something to scan the image of the phone and see if I can find those .xml files and maybe a twrp backup if I'm lucky. Although if the entire .img contents is still encrypted and not actually just a corrupt android filesystem, I think I am hosed on this option.
I would prefer option a) but I didn't know if anyone had any insight on this. I thought maybe there would be a way for me to get into the filesystem via ADB maybe and clear out some botched encryption cache or keystore/etc in order to get it to mount again. I'm also not sure if you're able to downgrade the firmware or modem either from 9 to 5 (even though I never got errors on downgrade). Thoughts? Am I just royally hosed?
Tried option b. Nothing but garbage. I made a backup of the .img file this time... so still would be willing to try option a) unless anyone thinks that this is impossible.
Edit: yep... may be too late... https://forum.xda-developers.com/on...-9-0-3-5-0-8-firmware-barrier-t3941164/page18
To my knowledge the data partitions content is unrecoverable lost after the reboot from 5) to 6). The img contains the messed up (and still encrypted) dm0 container but without the enctyption footer which is "outside" the dm0 container in sda15 (aka userdata) partition. To decrypt the img you are missing the device dependent key (an encrypzed partition can be decrypted only on the device the enctyption has been done on) as well as the encryption footer (which is messed up after the reboot).
Format data (not only wipe!) and start over.
Thanks for the reply. That makes sense and is what I was afraid of.
I wonder if it would be possible to regenerate the crypto footer by doing something like this to get the HMAC keys and then flashing a rom to recreate the cryptofooter and then editing the key values to reflect the old cryptofooter values based on the KeyMaster extraction via this exploit.
http://bits-please.blogspot.com/2016/06/extracting-qualcomms-keymaster-keys.html?m=1
It might depend on how much of the cryptofooter is left and whether or not 5.0.3 is vulnerable to these CVEs...
I’m not sure if I know enough about the KeyMaster structure to know how to rebuild it even if I were able to retrieve the HMAC keys.
I also know TWRP now supports EDL so perhaps there is something with a Qualcomm tool I could yse to assist.
Obviously this would mean security issues for everyone on these older builds if I am able to regenerate the crypto footer.
Are you aware of adb commands or likewise that I could run to survey the KeyMaster damage?
As stated: to my knowledge the data is lost after the first reboot with the 9.0.x bootloader.
If you search the official los thread (don't remember if 17 or 16) you'll find some detaled postings on restoring the keys after updating the bl from 5.0.x to 9.0.x. The user, who has examined that has failed, but perhaps it helps to shine some light on your questions.

[Q] bootloop after insufficient space rooted

I have rooted my m10g using magics via twrp and also applied the "no-dm-verify" patch but I didn't notice about the "forced data encryption" patcher here so that's reason why I didn't patch it at this point! anyway the data section was mounting without any problems but after I reboot recovery I was getting error In mounting the data section I just ignore it and I was able to boot into system normally but after some days exactly after "insufficient space" I just rebooted for some reasons and after that the device won't boot anymore / stucked at bootloop...!
I was able to see the home screen/touch wiz about 4 seconds and after that it's reboots again and again (In this point I tried to delete unwanted files quickly but there's no luck).
Things I have tried:
- flashed an recovery.img extracted from combination firmware and tried the "lacking storage booting" an option from stock recovery menu the device started in safe mode (It's says something like this: please bacup your stuff and then perform factory reset) but it's still won't boot (bootloop).
- twrp decrypt (I set no password there but I just tried In hope of chance) btw twrp never asked before to decrypt my data or to enter any password.
- I did twrp backup to my ext-sd and decompiled the boot.img to see what can I do (but after magics's patch I can do nothing).
- Pulled full userdata (mmcblk0p26) section also the emmc (mmcblk0) and tried to mount via linux reader windows tool / opening via 7zip but still can't access the userdata section. also tried to open the dumped userdata via hex editor but still can't see anything(looks like encrypted).
Things I want to try next:
- Format the data section after that try to restore the dumped userdata section via dd command.
- Enable usb debug at boot time and try to adb shell stop then pull all important data from the device.
- Inject custom script in stock_recovery.img to copy all internal files to the externel-sdcard (or even delete some huge files that I'm pretty sure of their path).
Notes / just to be clear:
* Flashing the stock kernel will encrypt the userdata section and the bootloop will stop but I'll lose all my data (I know that so I was just switching from the stock recovery to twrp).
* I could just perform a format data from the recovery menu / twrp or just flash the stock firmware to fix the booting problem but first I need to all my files get back.
Looking for any help in things that I want to try next.
Finally after a lot of tries I have solved my problem...!
How?
Short answer: ClassyKitchen
Long answer:
I just started creating my first rom In ClassyKitchen and I just enabled adb and removed dm-vertify via the kitchen and after the rom has prepared I just flashed through TWRP after I reboot the phone wasn't able to boot (stucked at first samsung logo) switched the device to download mode and I flashed system only using odin... after that phone started with setup wizard! and it's was still in safe mode (the backup message was still showing also) anyway I completed the setup wizard then check the home screen and apks I have installed wasn't there...!!! I opened "My Files" and finally I was able to see my files again!
I just copied all my internal sdcard to my external sdcard...!
After the copy ends I tried to exit safe mode to get my installed apks/contacts again so I just rebooted the phone to exit from the safe mode! But after the reboot "custom binary flashed bla bla".
I flashed stock "boot.img" and "recovery.img" using odin But as I said in the first post data encryption was there...!!!
Anyway I flashed full stock firmware after that I unlocked my OEM and flashed TWRP again and I restored the emmc dump using dd after restore completed rebooted the phone and it's back to it's state...!
this time I just flashed the patched boot.img (ClassyKitchen) and after the reboot phone started normally with setup wizard as said above! Connected to wifi unlocked my OEM and I was trying to get out of safe mode I rebooted and rebooted and power off but I wasn't able to disable the safe mode...!!!
I tried to root using magics but it's failed (the boot was patched by bla unsupported something like that) also the data section was still unmount able! In the TWRP
Anyway I just stopped at this point! Because I have reach my point (Getting back my sdcard data).
Notes!:
* All thanks goes to the author of ClassyKitchen.
* TWRP I was using found here.
* Odin I have used found here.
* I was using the same firmware version (PDA) installed in my phone.
* I have unlocked my OEM using this method the first time I have used it's taked from me only 3 days!.
* The idea of taking full encrypted emmc backup was by this post (I was getting some error messages so I just used "dd if=/dev/block/mmcblk0 of=/your_external-sd/mmcblk0.img" In case of "no space left error" format your externel-sdcard to ext4 and try again).
Sorry for my bad English x).
