T-Mobile Springboard S7-303u
Was on S7-301u stock, works perfectly
Tried to update SuperSU from CWM
I might messed up and mis-flashed the CM10.1 Sep.10 by after_silence
http://forum.xda-developers.com/showthread.php?t=2045808
Rebooted, stuck at the Huawei logo screen (logo, instead of boot animation)
dload folder stock recovery, still stuck at the Huawei logo
Fastboot fine, free to flash recoveries
Formatted everything in TWRP, flashed CM10.1
Booted into system perfectly, IMEI/MAC all gone
Reflashed several times, still only CM10.1 works, with IMEI CHANGED!!!!!!
IMEI SV: 00
SIM lock also relocked (previously unl*cked might be related to changed IMEI)
Even with the T-Mobile SIM, can call/text/HSPA+
Correctly reads SIM operator, blank Net operator
Additional observations:
Only cm10.1 kernel will boot system
With stock kernel + cwm/twrp, cannot manipulate internal storage (system/data/cache...)
A white screen right before booting into recovery
TWRP keeps saying "Unknown File System: datamedia" "Updating partition details..."
It looks to me:
1) internal storage is either collapsed or changed into some different format (only accessible by cm10.1 kernel)
2) to the hell of it I cannot understand where does the different IMEI come from
3) collapsed radio files? (ADB pushed Tmobile stock before flashing cm10.1)
Please kindly input. I do not care about stock ROM, I just want my original IMEI back, want correct Net Operator, want SIM lock gone. Ideally the storage is restored, so that it is back to normal...
Many thanks to all!

hi all, my friend got mediapad and he wanted custom rom so I flashed twrp recovery and his tablet became bricked, it shows huawei logo, then white screen and then after few seconds it shuts down, I tried to restore my backup to his tablet (CM10.1) via twrp and then it booted without problems but when I do wipe data/actory reset, the white screen and bootloop appears again, where is the problem? in twrp recovery? should I choose cwm for his device? twrp shows error "E: unknown filesystem datamedia" (also on my device but mine works without problems)

Just a follow-up to my earlier "used twrp to wipe everything": re-applied (i.e.
$ fastboot flash recovery twrp.img
with the trwp.img from auto_recovery, but booting the system still goes through the same process:
teamwin logo, then:
E:Unable to mount '/data'
E:Unable to recreate /data/media folder
E: Unknown File System: 'datamedia'
Updating partition details...
E:Unable to mount '/data'
E:Unable to mount internal storage
E:Unable to mount /data/media during GUI startup
E:Unable to locate page (main2)
Formatting Cache using make_ext4fs...
Done
E:Unable to mount /data when trying to read settings file
E:Unable to mount '/data'
After the above, if I power down and back up, I go back to log screen, then immediately "Encryption unsuccessful", with the two options:
"Reset tablet"
and
"Encrypt tablet" ... choosing the latter asks for a key which I do not have. Choosing the former goes to ... you guessed:
teamwin logo, then
E:Unable to mount '/data'
E:Unable to recreate /data/media folder...
Any ideas how to recover from this?

This might not be the case because the stock firmware was once working...
but if there are 2 versions of mediapad, CM could have support for only one....it can be something like on my HTC Desire S (first models have sony displays and second made in 2012 have hitachi mddi displays) - I have version with MDDI display and therefore CM does not boot on my device but stock firmware works on both versions...so maybe SU-303u is a bit different than SU-301u

you said that you got message about unsuccessfull encryption, why did you wanted to encrypt your device? maybe it failed and now partitions are unaccessible or corrupted

That's not what I said, but some quotes from others...
I never tried to encrypt, but I will try to encrypt and decrypt and see if it helps.
you can try flash stock rom via fastboot manually every partition

Is there any detailed instruction of how to do this? I tried fastboot push of a bunch of files from T-Mobile stock rom, but it did not help.
Not sure if it is the same thing as flashing partitions...
unzip the stock rom somewhere, boot tablet into fastboot mode, connect usb, then open cmd, change working dir to dir with unpacked zip and via command 'fastboot flash <partition> <filename>' flash every file, partition names are the same as files names (but without extension)

Tried and did not help. This is actually what dload folder is exactly doing...
Now it is not the contents in those partitions are corrupted, but the partitions themselves are corrupted. Pushing recovery files in whatever way won't fix partitions...
Problem solved by luck.
Flashed TMO stock
then S7-302u stock
booted into system
said "last encryption failed, encrypt again or reset?"
chose reset
then everything back to normal
never tried to encrypt the tablet
not sure what happened.
might be some bug in the stock S7-301u ROM
which told the tablet to do crazy things.
Congrats :good:
Can you share your both files which makes you happy

alright i have this problem and i am quite panicking now.
i will set everything straight , i hope someone reading the forums can help me asap !
- have a sgs2 unbranded (hk)
- has ICS 4.0.3 stock rom, rooted.
- i don't remember if usb debug mode was enabled
- i messed up in some way with the file /system/build.prop but there is a backup in /system/ called build.prop.bak
- phone doesn't boot anymore as it's stuck at the logo
- recovery and download modes work however
#need a way to delete the build.prop and replace the bloody file with the one backupped. I would like to avoid having to format the phone as i do not remember when was my last kies backup...
what i tried:
-adb shell: it doesn't work. for some stupid reasons the drivers won't be recognized (i have download android sdk and usb drivers), but when i plug the phone in recovery windows just says Device Unknown and even if i update drivers manually it would say that current ones are functioning so no need to update.
if i connect the phone to usb while it's stuck at boot logo, it would recognize the device through samsung drivers (except MTP of course, that would give error).
in both cases adb shell doesn't list any connected device: even if i kill-server and start-server it still doesn't list anything.
-tried using droid explorer in both frozenboot mode and recovery mode, doesn't see anything.
-tried using that other program called SuperOneClick or something like that, that has a "check drivers" button in advanced: if the phone is in recovery pressing the button doesn't do anyhing; if the phone is in frozenboot it asks to download and install some drivers but when i press yes a message appears with " no more data is available " !
i tried this procedure on both win7x64 and winXPx86: same results. reading around , someone says that adb shell will never work if usb debug is de-actived, like i said i cannot remember if that's the case.
-zip package: i created a package to try and overwrite the file with a custom working one i got. i put the package in the root of the micro sd , put the sd in the phone and booted in recovery.
but when i am in recovery the bloody CWM 5.0.2.7 says error to mount /sdcard, or E: could not mount /sdcard , same if i try to mount/unmount /sdcard. if i go to mount external usb card or whatever it says that a file or a lib (cant remember the exact message) was not found.
i have no more ideas of how to solve this, please be patient :<
edit: is there a way to soft format the system folder so that i don't have to properly wipe all my user data and it only affects the system without other contents?
If adb doesn't work hen you are in trouble, better download some non wipe rom and flash it over the existing rom so that your user data will still be there.

can you expand on this?
give any suggestion/example?
isn't there a soft temp rom for emergencies like this that you can just start, make modifies to fix and reboot (similar to the process to boot ubuntu on windows, fix issues and then restart normal windows? )
i would so like to make adb work.. but how.!!!
probebly will not work but try backing up of your ROM from CWM working or not..then just back up current one...
you can restore apps & data lateron from nandroid backup with some application like titanium backup donated version.
i made a backup . but since the external sd card isn't found by the recovery, now the backup is sitting on the internal memory.
the problem is that, if i flash something with odin now, won't odin wipe everything in the internal memory killing my backup as well?

nope....it will be there dont worry,
just check one more option, go to storage and mount, there is one option mount usb storage, after connecting your phone to PC just mout that and check, are you able to access the SDcard from the computor ot not, if yes, just copy paste your backup to the computor.
then flash a firmware from ODIN
Did the very same thing myself yesterday.. Most ICS-roms from Samsung is non-wipe, so you can just flash it over again with Odin.. Then you just need to root and make customizations (if any) again

could you be more specific on the process ? can you suggest me one to flash with odin ? i need to enter the OS , transfer my backup on my hard disk and then restore the whole thing.
currently my kernel is CF-Root-SGS2_XX_XEO_LPQ-PROPER-v5.4-CWM5.tar

you try to reflash once more CF-Root (.TAR)only from odin
then check "E: cant mout...error" is rectified or not.... also check booting or not,
still no hope...you flash the same firmware again and Cf-root, your SD card data will be there for sure as far as our expereicne till now..
first part of your comment: i tried reflashing the kernel; no changes. same errors
second part: shall i try using the same firmware from my previous post then?? not other roms? after that i will put the root and check if internal memory is still there. if it is i will copy it on my hd and restore.
if it is not there anymore..............
so the end of the story.
thanks to anyone who helped.
the resolution was much easier than everything else.
opened odin, pda loaded my same firmware which was the HK stock update to ICS and reflashed.
what it did was apparently and overhaul of the system folder, that's it.
any data was still there, as well as the backup that i did and all my apps etc etc etc.
however especially at first it looked a bit unstable, with processes failing randomly. now it seems it has stabilized a bit, but still when i try to run a Kies backup, the phone kies process dies and the backup gets stopped.
i still don't know how to fix this, but i'll be looking into it.
so, the morale out of this was at least for me: if there is some **** up within the system folder just reflash the same rom installed. i feel so stupid now for having made such a fuss when the solution was so easy and straightforward
NICE that you finaly came across and able to boot , now you make the Titanium back of your all apps and data transfer to PC....forget the system data.
and move to a nice stable ROM
"Unfortunately, wssyncmlnps has stopped"
anybody knows about this?
Hello,
My Tablet S is in deep need of expert help to see the light of day...:crying:
History:
I've rooted it about one day after the working exploit was found, ran Condi's AiO tool to update, and everything went fine.
At once, I used the "reinstall to factory settings" in the Settings app, which gave me a happy - if somewhat unstable at times - tablet.
It suddenly stopped working and remained stucked at the Sony logo.
Having no other option, I restarted in Recovery (Power-Volume+), and tried to update the system from SD card :
- with latest Condi's R5a zip : signature error
- with stock encrypted Sony zip : update blocked (yes, I left the tablet running about 8 hours without a move from the progress bar)
In the Android Recovery, I then selected "Reset to factory settings". Which seemed to do its thing, except that...the tablet still was stucked at the Sony logo at boot.
Going to Recovery again...
Code:
E:Fail to read boot logo flad
E:Can't open /dev/block/mmcblk0p5
(No such file or directory)
E:failed to mount /cache (No such file or directory)
E:Can't mount /cache/recovery/command
E:failed to mount /cache (No such file or directory)
E:failed to mount /cache (No such file or directory)
E:failed to mount /sdcard (No such file or directory)
E:failed to mount /cache (No such file or directory)
E:failed to mount /sdcard (No such file or directory)
E:failed to mount /cache (No such file or directory)
I can see the following device with ADB :
Code:
./adb devices
List of devices attached
0123456789ABCDEF recovery
and that's about all I can do with the tablet now.
Code:
./adb shell "ls /"
- exec '/system/bin/sh' failed: No such file or directory (2) -
One word remains: PLEASE HELP !
Is there any way I can dump a working system on the tablet in this state?
Note: I'm not afraid of running anything arcane command/script/setup.
Strange because the shell binary cannot be found but it can be wiped.
It is possible that the System partition is gone.

Yes indeed, I'm pretty sure that the Recovery option "Restore to factory settings" did wipe partitions...and failed to write anything sensible to them afterwards, or to recreate them at all (if that makes sense : I am far from sure of what the whole process really does and whether this is an Android standard or Sony-proprietary).
So, I'm there with my half-baked tablet ... any kind soul with the know-how how to revive it?
sorry to be the bearer of bad news, but I have had the expect same thing happened to my tablet s, all of sudden it stopped working, stuck on sony logo during booting, can't mount sd card in recovery mode, etc etc. Chances are your mother board is damaged. Might be a good time to send it to sony for repair. Good luck
since you have root,look here

Data partition is still there though.
The recovery has its own shell for sure since you are rooted.
The recovery has its own binary and adb support.
Here is the boot order:
Bootloader>Kernel>Boot Animation>System
When the Sony logo flashes thats when it switches to the Kernel but since it did not do anything it is possible that there is missing files in the data partition.
Bootloader = On a component on the motherboard somewhere
Kernel = Data Partition
Boot Animation = System Partition
System = System Partition (Obviously)

maybe kernel is not on data patition.
kermel is in rootfs.which is split with inner mmc dev(or in a hidden partition)

Yeah true but the question is did the Sony logo flash for a moment, if it did then it switched to the kernel successfully.

Yes indeed, the Sony logo flashes (and that's a fairly nice indication for the right time to press Power again and enter Recovery afterwards!).
Anyway, the tablet froze from time to time just entering Recovery (screen with the green/white dots), then I was able once or twice to start restoring a system image from the original Sony encrypted-signed ZIP so gracefully provided by condi in his Google Drive , but the process froze at different places!
I guess there is definitely a hardware issue (such as a faulty memory chip, if not a grilled processor), so right away it went to repair.
If it comes ever back as "repairable and repaired" I'll inform here!
Thanks to all for the attempts at helping!:highfive:

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.

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

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)

/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)

If you are not sure which line to change, I have the fstab.mt799 file attached with this post. You can simply replace your file with this one.

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

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

Nabi2 not found
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!
Swipe to restore
I am trying to return my nabi to stock, i can get to the screen that asks you to 'swipe to restore' but the screen is not responding. I dont have issues with the touchscreen normally

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.

Yes this is enabled, as without it I am unable to run nabilab etc. The problem is TWRP & the version of software I am running on the tablet?

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.

Hi, I bought it as a reconditioned did unit. Turned it on, updates it (wifi worked) and then had this problem, so no backup to go back to unfortunately
This is a CyanogenMod 12.1 ROM for the Exynos3470 based Samsung Galaxy Tab 4 7.0 LTE (T235/T235Y).
DO NOT USE IT FOR T230(NU)/T231 OR YOU WILL BRICK YOUR DEVICE
Although T235 and T230(NU)/T231 (T230:WiFi / T231:3G) share the "Galaxy Tab 4 7.0" name they are not related in terms of hardware due to the different SoCs used (Samsung Exynos3470 vs. Marvell PXA1088).
Hence please do not ask for support or ROMs for the T230(NU)/T231.

Disclaimer:
You flash this image at your own responsibility. I am not responsible for any damage that might be caused by flashing this image (bricked device, lost data, ...)
Flashing this kernel image will trigger the KNOX counter, so your warranty will be void.
Applications that use KNOX (e.g. "Private Mode") might not work anymore when returning to the stock ROM, as the device is regarded as compromised. Do not flash this ROM if you need those applications.
The image is only for Tab 4 7.0 SM-T235 and SM-T235Y (Exynos)
It might be instable, crash your device, drain your battery, or even might damage your smartphone
Backup your data before flashing and check if the original firmware is present (e.g. at SamMobile)

Before you start:
Backup your data, like call history, contacts, sms, WhatsApp messages, favourite app settings that are on internal and external sd (by using Titanium Backup or other apps available on PlayStore). At least all internal data will be lost in any case. If you have bad luck you might also loose data from your external sd card.
Download:
Odin3-v1.85
TWRP 2.8.7.0 recovery image [09/08/2015] (AndroidFileHost Mirror)
CM 12.1 ROM (AndroidFileHost Mirror)
Google Apps (contains Google Play, ...) for Android 5.1.1 from Jajb (Recommended) or the one that suits you best from Consolidated GApps.
Install recovery:
Reboot your device into Odin mode: turn off your device, then press Volume-Down + Home + Power button at the same time and release them.
Confirm the following warning message with the Volume-Up button.
Connect your device to your PC via USB
Make sure the device driver's are installed on your PC
Start Odin
In Odin select PDA and select the recovery image (recovery.tar.md5)
Check that only "Auto Reboot" and "F. Reset Time" is set
Click on "Start": the kernel image should be flashed now and the device should reboot afterwards. By flashing the recovery, your warranty will be void.
After the recovery flashing process was successful, power of your device. If not restart into Download mode and flash again or flash the stock rom.
Before you flash:
You need the latest TWRP recovery (see links above). Otherwise TWRP might not be able to flash the ROM.
Wipe the device to avoid problems with remaining files from the old installation (see instructions below). This also applies if you already installed an older version of CM 12.1.
Flash CyanogenMod:
Reboot into recovery mode (Press Volume-Up + Home + Power button)
If you come from a stock ROM, this is your opportunity to make a Backup of your phone(Backup, then select Boot, System, Data, then swipe to backup). Note that the recovery might fail to restore the backup when you want to go back to the stock ROM (for me it got stuck after a restore during boot. But the backup was made with a different version of TWRP, so it might work in general) - simply do not expect too much of it at the moment.
If you haven't copied the installation files yet, you can now copy the GApps and CyanogenMod zip to your internal sd or external sd (be careful not to put the files into the data directory of the internal sd card as this will be deleted in the next step). Be sure that MTP is enabled (inside Mounts, click on Enable MTP), then, from your pc, copy the files. If MTP does not work from recovery, try it directly from Android or remove the external sd card from the phone and put it into your PC.
Wipe Dalvik Cache, Cache, System and Data (inside Wipe -> Advanced Wipe). Do not report problems if you did not wipe those partitions as the problems are most probably related to this!
Install the CM 12.1 ROM zip-package
Install the GApps zip-package
Reboot the system and enjoy a Lollipop
How to root:
No SuperSu is needed as CyanogenMod already comes with integrated root support. Root access is disabled by default.
You normally do not need root access. If you want to activate root access for apps, do the following:
Open the Settings menu, select "About Phone"
Tap on the "Build number" entry seven times. You should be notified, that the developer settings are now active.
Open the Settings menu, select "Developer options". Enable root access by selecting "Apps" in the "Root-Access" setting.
In case you want to go back to the stock ROM:
lf you do not have the latest stock ROM you can download it from SamMobile
Reboot your phone into Odin mode
Open Odin on your PC and connect your smartphone with your PC via USB
If you have a zip-file unzip it so that you have a .tar.md5 file
In Odin click on the PDA button and select the .tar.md5 file. Then press "Start".
Normally the stock rom fails to boot as the data from CM12 is still on the data partition. So after flashing the stock rom, reboot into recovery mode (it looks a bit different now). First wipe the data partition, then wipe the cache.
Reboot

Developers welcome
Help from other developers is always welcome. See the bug/feature section and this thread to see what is missing. Just give some short info (here in this thread or PM) that you want to work on some issue or feature so that work can be synchronized. Maybe there are also other devs that want to work with you on the same issue.
Knowledge in how the kernel works and good programming skills in C, C++ and Java would be nice but not necessary for all problems. At least you should be able to build the ROM and test your changes yourself but you do not need experience in porting ROMs.

do you have included selinux_defconfig in your twrp kernel?
androidboot.selinux=disabled at twrps kernel cmd line should be removed
i wiped system and all partitions using your new twrp but when i install the zip file then /system becomes unmountable
/system is formated ext4
should i try to format it f2fs ?

The default selinux setting is enforced. As the selinux configuration files are not complete, Android would not boot.
Setting androidboot.selinux=permissive might work, but when I tested this setting on my S5 mini, it was rather unstable for some reason.

T235 and T235Y definitely use Exynos 3470 SoCs. Here an extract from the T235Y default.prop:
Code:
ro.product.model=SM-T235Y
ro.product.name=degasltezt
ro.product.device=degaslte
ro.product.board=universal3470
ro.chipname=exynos3470
The default.prop file of the T235 is similar, only that the product name is degasltexx.
Marvell's PXA1088 SoC is used in the T230/NU which is the non-LTE (WiFi-only) variant of the Tab 4 7.0.
Marvell's PXA1088 and Samsung's Exynos3470 are totally different and have nothing in common (except an ARM core), the same applies to Qualcomm's Snapdragon. There are many websites that mention wrong SoC names as Samsung's naming scheme is rather confusing.
The same applies to the S5 Mini: G800F/M/Y -> Exynos3470, G800H -> Qualcomm Snapdragon.

Code:
Info: format successful
I:mkfs.f2fs -t 1 /dev/block/mmcblk0p18 process ended with RC=0
Done.
Why was the system partition formatted with f2fs? The default file system is ext4.
The TWRP partition table is hardcoded to ext4 so that's probably the reason for these lines:
Code:
E:Unable to mount '/system'
I:Actual block device: '/dev/block/mmcblk0p18', current file system: 'ext4'
Could you reformat it with ext4?

Did you flash the stock ROM with Odin?
And afterwards wipe the data partition and then the cache with the _stock_ recovery (as TWRP is not available after flashing the stock ROM)?

Short summary:
interstellar22 and corneo tried it so far and both got the error message "/system unmountable"
Strange that corneo was able to generate an error log.
@corneo: did you create the log with adb?
At least according to corneo's log, it seams that after the F2FS format the partition is reformatted with EXT4 afterwards:
Code:
Formatting system using make_ext4fs function.
It also says:
Code:
erasing 588800 blocks
blkdiscard failed: Invalid argument
writing 134395 blocks of new data
lseek64 failed: Invalid argument
I:Legacy property environment disabled.
E:Error executing updater binary in zip '/external_sd/cm-12.1-20150627-UNOFFICIAL-degaslte.zip'
Error flashing zip '/external_sd/cm-12.1-20150627-UNOFFICIAL-degaslte.zip'
Not that sure about what causes this error. Maybe the partition sizes have to be changed.

i've created the log in recovery and copied it to sd.
now i flashed the tab again with odin and try it again. same issue...
Gesendet von meinem One M8
i managed to get the original firmware back with odin
could it be that the system.new.dat file is corrupted ?
i had formated system with ext4 then did the update and was still getting unable to mount /system afterwards
so most probably the system.new.dat file has some problems or i have no idea why i cant mount /system afterwards
Maybe it is caused by wrong BOARD_...IMAGE_PARTITION_SIZE values in BoardConfig.mk.
Could you please post the contents of /proc/mounts and /proc/partitions:
Code:
cat /proc/mounts
cat /proc/partitions
The above should be performed from the stock ROM. The device must be rooted.
Hmm, the problem might be here:
Code:
Patching system image unconditionally...
blockimg version is 2
erasing 588800 blocks
blkdiscard failed: Invalid argument
writing 134395 blocks of new data
lseek64 failed: Invalid argument
588800 * 4096 = 2411724800 bytes (2,2GB)
This is the value of the BoardConfig.mk taken from the S5 Mini (BOARD_SYSTEMIMAGE_PARTITION_SIZE := 2411724800).
But the system partition is only 2233466880 bytes:
Code:
/system | /dev/block/mmcblk0p18 | Size: 2096MB Used: 1828MB Free: 268MB Backup Size: 1828MB
Code:
I:wipe_path '/system'
Formatting System using make_ext4fs function.
Creating filesystem with parameters:
Size: 2233466880
The system.img itself is only 500MB in size. So I guess reducing the image size should fix the problem.
An updated ROM is available. The image sizes have been reduced. I hope this fixes the problems with the system-partition.
Also use the new TWRP recovery as the partition sizes might be hardcoded in the old one.
good news! new recovery and system image works! very smooth so far, searching for bugs now. the only one i found are the extended settings option. it doesn't work but thats no problem for me. thank you very much!

Press Volume Down + Power to activate the recovery. When installed properly, the device should vibrate funnily, purple LED should appear and after a couple of seconds you should see the TWRP screen.
Enjoy!

Nice work! Finally no more decryption problems on the X!
Working well, thanks!
One question ; is it possible to reboot the recovery via twrp reboot menu (or use an app like flashfire /flashify)? When I've tried the phone boots normally instead.

Unfortunately the reboot Recovery does not work from the specifics of the section, but in the future maybe will be fixed. If I don't find how to fix that button will be removed.

Good to know, thanks for clarifying
Is there a difference to the 3.1.0 TWRP recovery from the Poison thread?

Yes, this TWRP version has decryption problem fixed. So you can acces internal memory(and make a full backup) without the need of doing a full whipe & format /DATA

I install zip file from my external sd card only.....no full backup...
someone knows a recovery that finally works?

I've installed and tried this TWRP in my Xperia X with MM. Very nice that it can access the data partition! I did not try to install any zip yet.
Some problems I've seen:
dmesg.log: no output
recovery.log: https://pastebin.com/EwbtuC9q
What is interesting in the output:
Code:
I:cmd: /sbin/exfat-fuse -o big_writes,max_read=131072,max_write=131072 /dev/block/mmcblk1p1 /external_sd
CANNOT LINK EXECUTABLE "sh": cannot locate symbol "__fwrite_chk" referenced by "/sbin/busybox"...
I:exfat-fuse failed to mount with result '', trying vfat
I:Unable to mount '/external_sd'
I:Actual block device: '/dev/block/mmcblk1p1', current file system: 'vfat'
Looks like something is not right with the busybox in the image. Maybe it is that what is causing the external sdcard (in my case in exfat filesystem) not being mounted?
Thanks

This problem is almost resolved, just need to test, but I don't have time to compile recovery. In the test version recovery without decryption, problem solved.

This issue failed to reproduce, and yet there is no solution. You the problem is not in Busybox, and something else.

For whatever reason I'm not able to boot into TWRP like I should be. I've used the poison version of TWRP before so I know what to do, and yet the phone will just boot normally despite holding volume down and power when off.
I know that TWRP is installed though as I am able to boot to it if I first boot to the bootloader using a USB cable but that is very cumbersome to do though.

Clearly for the image available at your dropbox there are some libraries dependency errors, not only for the 'busybox', but also for other binaries that are in /sbin.
I do not know why this issue is only happening on my device since you said you can't reproduce this error. If there is anything I can do to help solve this strange behavior, count on me. I am an advanced linux user, but not too familiar with android specifics.
On latest 333 ROM for UK so that fingerprint scanner works on my Xperia X F5121.
I also modified by kernel/boot so that TWRP doesn't brick (actually boot loop) the device like it did the first time. After using these awesome instructions flashing TWRP recovery from here didn't kill the device any longer: https://forum.xda-developers.com/crossdevice-dev/sony/root-root-stock-firmware-modern-sony-t3558904
I was able to take an early nandroid backup before a bunch of Titanium restores, etc. Now I get stuck at "Backing up data" step and it literally doesn't move to the next file. Attaching an image of where I get stuck. FYI, I do use password encryption on the backup and I did disable MD5 creation... still just stuck.
Next tests are to:
see if the stall is on the same exact file number
try no encryption
do a check disk (fsck) type of repair just in case I have corruption --- on my brand new device
Any suggestions greatly appreciated!
UPDATED:
I only back up Boot, System & Data (the default)
On second attempt it stopped at file 18869 of 22065 --- so it does jump and not consistently stop at a certain file.
