MT6582 - Root no access to SD card and other issues - Android Q&A, Help & Troubleshooting

I already have read multiple threads about this issue, however, this is sort of a more specific issue I ran into. The device I'm using is a MT6582 Karbonn Titanium S25 (sold under a different name in my country) with a pretty recent build of the software which is a completely stock Mediatek Android 4.4 build.
The issue here is simple enough - root can't access the external sdcard (sdcard0), but the user can oddly enough. This causes file operations to goof up and that's really annoying me. I can't copy any file from an external sdcard, but instead, I have to copy it to the internal one first and then wherever else on the phone.
I did do some crazy things which caused me to lose the original stock system image, but I still had the files of it so I had to create an updater script and a flashable ZIP of it, though, I don't believe that's what's causing the issue here, since I had an older build running which has the same issue when rooted. Unfortunately, this build they flashed on my phone (in the store lol, with SP flash tool of a newer build) seems private to them. I asked them specifically if it was available for download anywhere and they said no.
Using the utilities provided on the Play Store did not fix the issue for me.
On another note, BBS and V4A seem to have been affected by a similar issue as well. BBS can't read Kernel Wakelocks and V4A can't install its driver for some reason.
If anybody needs the ROM I'm using on my phone, feel free to ask! This one is special since there isn't a download of it anywhere available. Build number is: Karbonn Titanium S25_V1.7_20150203124356

[Q] HTC ONE X+ apps unable to access storage after installing custom ROM

Hi everyone,
I need some help with some errors that are occuring after installing the [International] 2013/03/05 AOKP 4.2.2 - 2.0b ROM.
I'm using the international version of the HTC ONE X+.
First off, I have to mention that I am quite noob at these things besides rooting and installing oxygenrom once on the HTC DESIRE, 2 years ago.
Let me explain the problems:
1) when connected to my pc via USB, I can access the phone's storage listed as sdcard, but there is totally nothing inside, and I am unable to copy anything to the sdcard.
2) Also when I try to download anything using the stock browser from this rom, the browser crashes, Google play also crashes immediately when I try to open it. File Manager (safe access mode) throws up the error message "the file or folder was not found" and is empty.
3) Camera and gallery indicates that there is no storage available.
After checking "storage" from settings, it clearly indicates 53.23gb available, 72.11mb (apps), 12.13mb cached data.
I've checked the recovery and discovered that my original data is stored in the directory /0/0/0/0/0, I suspect this is because I didn't realise I had to install the 4.2 kernel separately before I flashed the custom ROM that I tried to install the ROM many times before I realised my mistake and installed it correctly.
I suspect that somehow the ROM is malfunctioning after my mistakes while installing it, causing the many /0 directories and thus while there is available storage space, the apps are unable to read/write data for some reason.
I would install an old ROM version to try to fix this but as I have mentioned above, I cannot transfer any files via USB either.
I'm hoping that one of you can provide some insight into what has gone wrong and perhaps give me some advice on how to re-install your ROM without getting these errors.
If there is any further information I can provide to you please let me know.
Thank you for any help rendered
Same Problem
I've the same problem did you manage to fix it??
If you don't have important data stored on your phone yet, the easiest way is probably format your /data partition in TWRP recovery, wipe/factory reset your phone and the install the rom via "adb sideload" command.
In case you don't know what that is or how to use it, there are two tutorials in the HTC One X+ General forum on unlocking/rooting/flashing on this phone, everything you need to know is written down there.

[Q] ROM for corrupted phone (system damaged)

Ok, I'm new here and this is my first post, please be nice
Just got me a Guomi F3 (in Chinese, 国米 F3) and I'd like to do a clean install in English. I didn't know much about Android but I have been searching and learning to handle this situation I'm under..
I lost backup ROM and can't find a compatible one on the net yet.
This phone seems to be very new (and very minor) so I can't find a manufacture ROM or even manufacture's website..
Currently it keep showing an error message "System was damaged, The system will be unstable!"
The OS seems to belong to China Mobile (in Chinese, 引領3G生活) and it won't let me fastboot but I can access fastboot mode by ROM manager app.
Here's the spec of this phone;
- Platform: Android
- Android ver.: 4.4.4
- Android SDK ver.: 15 (Android 4.0.3)
- Kernel: Linux 3.0.8
- CPU: MT6592 2GHz Octa Core
- Root access: Yes
- RAM: 421MB
- System storage: 2.07GB
- Internal storage: 0.97GB
- External storage: 0.97GB
- GPU ver.: OpenGL LS 2.0 Spreadtrum Build
I need a custom ROM for the phone, any help would be very appreciated, thanks!
You should have done a backup before!!
Now you're helpless unless you get a stock rom or a custom rom
Use yuweng's recovery porting tool to get a custom cwm recovery(dont know whether it'll work on mt6592)
Then port a custom rom using a rom porting tool and try it
It'll be a long process but at the end of the day you'll get rid of the error and will have a custom rom too
Press thanks :good: if I've helped :highfive:
Hi arnabbiswasalsodeep, thanks for your reply :good:
I tried MT65xx Lewa OS Porting Tool but can't proceed it.. as there's no compatible lewa ROM, fails to install USB driver (Mediatek Driver Auto Installer) due to no unsigned drivers for win7.
I just hope that someone can modify or create ROM for this phone soon.. :fingers-crossed:
Use mtk firmware adapter
Many even port roms fron mtk6577 to mtk6589 using it
Press thanks :good: if I've helped :highfive:

Don't worry, your phone is perfectly fine. The system is NOT damaged at all. This iRoot chinese superuser crap is what is sending the scary message. The scare tactic occurs because you deleted some other chinese bloatware which came down via the iRoot software during the rooting process. There is one chinese app in particular which when deleted will download and reinstall itself. It is the one that pops up annoyingly every 10 seconds. It's like an appstore that's trying to force you to download chinese apps. You can uninstall it by putting the phone in airplane mode and uninstalling it.
When the chinese superuser sees that that particular chinese crapware is absent, it starts to send that annoying message that the system was damaged. Just ignore it. Of course, it is hard to ignore because it flashes constantly in the middle of the screen. But you can work through the nuisance.
You see, at this point, the phone is actually properly rooted! So what you do next is simply download a root file manager (Uninstall Master or ES File Manager for example), do whatever you needed while rooted then after you've done whatever you wanted to do in the first place, just use the root file manager to delete the chinese superuser program. It's called RL King or some such non-sense. THIS WILL SAFELY UNROOT THE PHONE. In other words, you will lose root, but it will get rid of the annoying fake message that your system was damaged.
Or you can root the phone, accept the chinese crapware and be happy. Me? i unrooted my phone. I don't want any chinese crapware on it. Who knows what other sneaky stuff iRoot is doing on there. I don't speak chinese so I have no idea what all the visible crapware was for. And if they get so upset that you delete the crapware that they would spitefully put this annoying message permanently on the phone, then I DO NOT TRUST THEM!!!
My advice is TO NOT USE iRoot or vRoot for rooting your phone. You will have no idea what nastiness they are inserting directly into the root of your system with superuser privileges!
Volte4G+ CPU: MT6589 4GB RAM, 120GB ROM 2.048GHz???
I have a message every 2 second saying "System is damage, please check!!!". The system is 100% OK besides this error message.
I have used iRoot. I have installed Uninstall Master to delete KingRoot but it does not help. There must be some more bugs?
The technical spec seems to be a fraud as well.
Please advise.

What is your phone make and model? Can't help you unless you provide this info.

System is damage, please check!!!
My Phone is a " Volte4G+". It is made by Spreadtrum.
The phone information is giving me the following info:
1. CPU: MT6589 (Spreadtrum 4G SC8830?).
2. ARM V7 architecture.
3. 8 cores
4. 2..048GHz
5. 4GB RAM
6. Internal Storage 120GB
7. 512GB micro SD Card (Installed by me)
The phone is bought from Malaysia.
Works perfect, but I can not find any tech spec that match this phone internal spec (can be fake?).
I have uninstalled KingRoot and it has nothing todo with the problem. I don't think iRoot or KingRoot is the problem (mybe emidiator). I have deleted all suspissios programs but there is of course hundreds other apps that can couse this problem!
You are absolute right about your assumption that a deleted malware program have triggered this messages.

I guarantee you that iRoot or KingRoot were indeed the source of the problem. What I said was, one of those programs downloaded the culprit without your knowledge. I know it for a fact because my own phone was completely free of all malware. I had a brand new, clean stock ROM flashed. I then tried to root with iRoot or vRoot. Immediately after rooting, I deleted a Chinese app that got installed by the rooting program. And as soon as I deleted that program, the annoying message began. So it had to be via the rooting process and it was because I deleted that crapware.
It's possible that it's an app that cannot be deleted even by AppMaster, or the root browsers even with root permission. This is because some of the virus apps install themselves into the system partition with an attribute of i (immutable) or a (annex only). You first have to remove the "i" or "a" attribute with a terminal emulator such as Terminal Emulator from PlayStore (but your phone needs to be rooted). The problem with those attributes is that a program like AppMaster, SD Maid or Root Browser will tell you the app was deleted, but once you reboot, you will quickly find out that the app was not deleted at all. Once you remove these attributes, you can delete the offending apps permanently. So to do this, you'll have to reroot your phone. Don't be afraid to reroot because once you're rooted, you can get rid of all the crap. Also, once you're rooted, make sure you also install busybox (download and install Busy Box X from PlayStore) because it gives you access to a better suite of Linux commands that you can use via the terminal emulator app.
There is another possibility for the problem. The annoying message may be a service and not an app. In that case, you need to discover what service it is and use the app called Disable Service to permanently stop that service from running (but your phone needs to be rooted). So you'll have to reroot and then use Disable Service.
Anyway, you have an absolutely beautiful phone. Love the specs. I wonder it it uses MTK or Spreadthrum architecture. If it's MTK you can easily and quickly flash back to stock with SP Flash Tool. Otherwise you have to use the Spreadthrum tools. You will need to find your stock ROM and flash it. That's the other way to deal with it.
Let me know how it goes. I can help answer questions at each step of the way. Just remember to take screenshots to help explain what's going on if you need help.

System is Damage
First. My goal withe phone is to install Ubuntu Mate and have a combined phone & Ubuntu computer.
On all tests this powerful phone have extremely low score. Reason, the tests can not handle 4G phones @ 2GHz and 8-cores or the phone is a fake or scam?
I have contacted the Seller on eBay about the Stock ROM. Normally they don't know anything..
Also I am a normal user with some computer knowledge, not a hacker or aUnix programmer.
I have downloaded and tested all programs you have suggested. Note! my phone is rooted.
The problem:
1 To use Service Disable or Uninstall apps in settings I need to know what app is causing the problem and I don't have a clue witch app I shall disable.
2. I can not find the Stock ROM to my phone.
3. I believe the my phone is a MT6589 SoC MTK device with 8-cores 2048MHZ and 120GB local storage.
At least that is what the phone is telling me.
Anyway, this is the future of computer/phones.
Possible Solutions
1. Buy another similar phone. Cost only $52 on eBay.
2. Take. backup of the new phone ROM and restore the backup to the old damage phone (delete internal storage first to get rid of malware?)
3. Compare installed apps on the phones and delete the differences on the old damage phones..
Can I use the therminal emulator to find the program causing my problem? You told me they have the "i" and "a" attribute in the mode. Can I look for some distinct features in the mode and use RM to remove the app.
In what directory shall I look?
Please advise

It's really difficult to tell which app is causing whatever problem you might experience on your screen.
There are a couple things you can try:
First look in Settings> Applications and flip over to the Running tab. Look for apps with strange names. Then find the app in the All apps tab and try to disable it.
Next, use a root browser and check the /system/app and /system/priv-app folders. Again, you are looking for apks that have strange names. You have to be really careful because there are some system apps that have strange names but they will often have an odex file with the same name right next to them. You can ignore these apps that have an odex sibling. WARNING: Don't delete any of the apk files in the system folders. First try to rename them to whatevername.bak. Be sure you have root permissions. If you can rename the file, then it is NOT the one you're looking for. Rename it back to whatevername.apk and try another suspicious file. If you cannot rename the file, it will throw a message like "operation failed"... THIS IS THE CULPRIT. And there could be several of them. These are the virus files that cannot be deleted by normal means because they have their attribute set to immutable or annex or both. (I'm assuming that you already deleted all the virus apps that can be deleted using a system app manager like App Master and only these stubborn ones are left).
I use ES File Explorer for my root browser. Just long click on the file you want to delete and select Properties. There on the file properties screen, I have the option to Copy Full Path. Click that to save the name of the file including the path (it will save something like /system/app/filename) so you don't have to manually type it later.
Then go to the Terminal Emulator app. Type su to get superuser privileges. Then type chattr -i -a /system/app/filename. This will remove the i and a attributes if they were on the file. Next type rm /system/app/filename. Obviously you can just paste the filename you copied to the clipboard instead of typing the whole thing and making mistakes on these tiny keyboards. Anyway, this is how to delete virus files that refuse to let you delete them. Lol. I have had to do this with infected phones that had 10 or more viruses permanently installed. This is why the copy full path is excellent. It removes the need for a lot of typing.
Let me know how it goes. But I did like your solution which was very effective....If these phones cost only $50 bucks, just buy a new one and extract the stock ROM from it. The only thing that concerns me is how could a phone so powerful only cost $50??? Sounds like a fake. I see a lot of Samsung Galaxy clones that show they have many GB of internal storage in the Settings. But if you run an app like Diskinfo on them, you'll see that they have very little RAM and very little internal memory. Some are so bad that you can't even install any apps on them because you'll get an insufficient memory error.

ROM for corrupted phone
I have tried everything and can not find the virus.
Is not in the /Syste/app or /System/pri-app. If I delete all apps and goes to safe mode the virus is still there so it most be on the root level. The seller can not give me a new phone, they are out of stock and they are totally fake. They are even programmed to deceive you and the test program, a deliberate fraud or crime. It is 479MB not 4GB RAM and 1.2GB ROOM not 128GB. The CPU is a 4-core 1GHz not 8-Core 2GHz. And it is the same with all the Chinese phones I have seen. However they are nice low end phones payed by the ads you have big problems with. And as in my case, when you try you have this message "System is Damage" you can't get rid of blinking every 2 seconds.
The only way I can see now is to find a Stock ROM that works and that is not east to an MT6589 CPU.
Any suggestions?

If it's not one of the apps that shows up in your listings of Running apps, then it is a service which you need to halt.
There is a root app called OS Monitor which you can download from the PlayStore. It will tell you exactly which apps and services are running at any given moment. Use it to identify which service(s) is(are) running when this message pops up.
Then use Disable Service (also a root app from PlayStore) to block/turn off those services, thereby permanently stopping the message from appearing.

Is the device rooted? Is it encrypted? Is the bootloader locked (by operator)?
Your EMMC may be corrupted. Forget factory reset. Hold down the volume DOWN key and then press power till the phone boots. You should see a menu. Select Clear or Wipe EMMC. Let us know what happens.

The message about "system damaged" comes from a virus process that is installed by certain rooting applications. That application is triggered when you attempt to delete certain apps installed by the rooting app. Nothing is wrong with your system.
What phone do you have have bro? Can't help you unless you state the make and model of your device. Also, what did you root with?

TCL S720T flashed and internal storage is lost

I bought a TCL S720T from China about two weeks ago. It has 4.2.2 with 1GB RAM and 8GB ROM and is based on MT6592. When I first got the phone, the internal storage was displayed as about 5.9GB out of which most (about 5.85GB) was available. I would like to mention here that when I connected my phone to the PC thru a USB cable, the total internal storage was also shown as 5.9GB on PC.
I did the following to the phone and now I am in trouble... plz help
As I bought it from China, it did not have Google apps. I rooted the phone to get these installed. During rooting I deleted some useful original apps.
I tried to restore the phone to factory settings but the deleted apps did not return (I do not know what did I do wrong). I started to search for phone's stock ROM but could not find it. Also all information on the web is in Chinese and that too no accessible from where I live.
After a couple of days, I found a ROM on "lewaos" website. It was translated from Chinese to "S720T Le Frog bottom package. Zip" and the website claimed that it was the original ROM. I thought that it is the actual ROM by TCL so I flashed it using SP_Flash_Tool_v5.1343.01. When the system rebooted, the radio was not working as the baseband was missing, however, the total internal storage was shown as about 4.90GB. I just want to mention here that I never backed up my original ROM (bad on my part).
There was another ROM update given on the same website for installation using external SD card. So, I installed the ROM, but this time the total internal storage wasshown as 1.09GB out of which 1GB was available. I got worried and tried to find other ROMs to fix the issue. I found some ROMs from website named "needrom" and tried them too. Whenever I use flash tool to load the ROM which I got from LEWA website, the phone shows 4.9GB internal storage but the phone radio does not work. However, as soon as I install any ROM using SD card, the internal storage is shown close to 1.1GB. I have even downloaded the official ROM update from "tclmobile" website and installed it using SD card, but the internal storage is still shown as 1.1GB. Also, whenever I connect my phone to PC thru the USB cable, the total internal storage is shown as 1.1GB out of which about 1GB is free.
While installing ROM thru SD card, I have always adopted the process of wiping the factory settings and cache in the recovery mode.
I would also like to mention here that during the process of loading ROMs, I lost the radio operation due to invalid IMEI, which I later restored using AT+... commands (thanks to xda-developer forums).
Having said all that let me summarize my problems:-
I have lost the original Stock ROM of my phone and no support is available outside China.
Whenever I install ROMs through SD card, the internal storage is 1.1GB, I want my actual internal storage ie 5.9GB back.
Please help me to fix my phone
Thanks
Maybe we can help each other i have a backup may work for you...
Hey what up dude,
I have exact phone, and similar issue. no backup, but I have a horrible boot loop for one MONTH now, I am going crazy, even the guys at china-devices.com are not much help. (But may help your problem).
I can't backup but i can access stock recovery and NEED to install CWM recovery via SD as the bootloop just blocks all attempts to connect the phone to the PC. I cant see my phone data but i know i have your ROM and model, using TCL factoryware. Octo the whole nine yards.
Another long time friend has a TCL S720T and he sent me a zip of a ROM backup he made. I can pass it to you via wetransfer or email attachment.
Note that his backup is UN-rooted so it should work OK, and be 'pure' maybe some factory crapware he wiped off it. and you will likely need to fix the IMEI issue, (or maybe not, and I am a newb so can't help you there, yet).
In return, could you tell me how you fixed your issue, what exact tools you used, and so on? Sepecially if used MTK driod tools what version and SP flashtools what version any and all info will be great thanks.
There is an app you can istall that shows you which apk are system apps and not to touch, i had it installed, but i am lord of the idiots, and went ahead and deleted the chinese keyboard, hey presto, one really great phone I had almost totally customised my way, now in a month-long boot loop and may never recover.
Wow. It was amazing to hear that someone else also has this phone but was sad to know that you are also facing problems. Please contact me on [email protected]. I will first try to resolve your issues then will post those solutions on xda.
By the way, I have resolved all my issues and my phone is up and running like anything. Thanks to android lovers all over the world. I will try to give you solutions one by one.
SOLVED! & Thanks Muiz!
SOLVED with this tutuorial... all credit to the OP, Muiz, I'm only passing it forward, this is a GREAT phone, hope to see more users soon!
If we address your first problem of not being able to boot the phone at all, I will propose to go to this link (use any English translator if you do not read Chinese) ... you may use www.micrsofttranslator.com
http://bbs.lewaos.com/learn-s720t.html
You will find these steps in a tutorial.
1, download the ROM and put it into the SD card root directory (on computer operation)
Download LeWa_TCL_S720T_JB2_ROM__XXXXX.zip ( from bbs.lewaos.com) and copy ROM package in zip format to phone external SD card root directory.
2, download the Flash tool latest version and unzip it to the desktop (computer operation)
Download SP_Flash_Tool_v5.1352.01, and extract it to your computer desktop.
3, download music frog end of packet (on computer operation) lewaos.com
Download end of Le frog, S720T package. zip and extract it to your computer desktop. lewaos.com
4, download and install the Flash drive Download MT65xx flash drive _ automatically installed. rar (lewaos.com ), and extract it to your computer desktop, double-click the InstallDriver.exe folder is automatically installed
If you desire to install any un-rooted original backup you have, to your phone, do not download the file in step 1.
To make the tutorial short; first install the drivers as mentioned in step 4. Then extract the file mentioned in step 3 in a folder on your desktop. Extract and start the flash tools utility and give the path of the folder you copied on your desktop. There is going to be a sort of file with name “MT6592_Android_scatter.txt”. Use its path to flash the ROM.
You will have to wait for some time, but the Flash tools will install the LEWA ROM on your phone.
rooting
can this be rooted with stock rom on it
what does the different roms look like, photos please
ok guys i have tcl s720 without the "t" whats the difference? i went to the chinese website & had a look around with an english translator & i see downloads for s720t but none for s720 .
i recently changed my rom from what it arrived with as play store didnt work & push notifications so i flashed successfully this rom
wwwdotneedromdotcom/download/tcl-720t-cm11-v2-w200s-lstyle-port/
this is ported from THL w200s which works well just a few slight issues with storage etc but better than what i had as play store works
what im also looking for is there actually a fully working rom for the s720 ? & where can i get a fully working stock rom for this phone? yes i have searched tirelessly but roms i checkout seem to have quite a few bugs so im just looking for a good stable one.
apart from few issues this phone im more than satisfied with

[Q] P780 - General Issues & Solutions Under one heading

Hi all
I have come across numerous problems with P780 and many issues that are addressed but scattered everywhere on the net. I believe it is high time to condense everything down here. These are issues that I have come across and I look forward if someone within the elite team on this forum can address them individually.
1st issue (Internal v/s external memory swapping)
Internal Memory keeps filling up although External Storage is chosen from the menu for future download and installation. Actually, all apps are de facto installed onto the internal memory. I had to download a 3rd party software to move them each and everytime an app is downloaded to the external memory card. Still after moving, the internal memory keeps filling up.
I have tried this solution but unfortunately it doesn't work: http://forum.xda-developers.com/showthread.php?t=2346389
2nd issue: (RAM)
Like you know, the RAM keeps over charging itself and each and everytime you have to clean it up. Came across this solution to increase RAM and I would like to know if this is genuine or not: https://www.androidpit.com/increase-phone-ram
3rd issue: Lenovo Launcher keeps crashing
Any solution to that? I used LiFE ROM. Want to know if there is a solid ROM out there that can overcome such issue? The numerous applications to be installed are found sparingly in several threads; hence if someone can group them altogether with relevant description of each of them that would be nice. Stumpy did an incredible thread here: https://drive.google.com/folderview?id=0B2ORIgaV4iacYmZHQmV0QXFpR0E&usp=sharing#list
But unfortunately, without a description of each of the file, it is difficult to know which is which.
4th issue: Installing new ROMs through Recovery mode
For instance I cannot install MIUI through this mode. I can only use flash tool to install a ROM. I donwloaded MIUI through their website but can't find the scatter file for relevant installation.
5th issue: Sound quality
People gets difficulty to hear us properly. Is that a hardware defect or software?

[GUIDE][CM13] Most important information

Official CM13 ROM, by Nikita Pro Android is availabe here:
http://forum.xda-developers.com/g2-mini/development/cyanogenmod-13-0-lg-g2-mini-t3260495
Preamble
Why am I doing this guide?
The main, developer's post has about 100 posts and it's really annoying to find useful information in this mess... The same questions appear all the time (I also had to ask them again). I decided to gather the important things in one place. Besides - ROM is quite unique and differs from others. If I wrote something wrong, tell me, I'll fix it. Sorry for my not perfect English.
I will look at the whole case as a simple user (who I really am! lol).
Stability
It is a subjective topic, so please take it with a pinch o salt. If I would have to rate the stability it will be 4 out of 6 (where 1 is a bricked phone and 6 is the flawless system work). System apps (like Documents or Themes) rarely can crash, but the system reboot fixes it. Generally every day usage is completely fine and you'll never get a random reboot on the go. What users have been reporting are problems with crashing default music player (confirmed by me). I personally noticed, that while using ProPlayer (IMO one of the best music players) songs rarely are randomly muted or skipped. Another thing reported is a signal losing (I haven't experienced it). GPS for me is going like crazy.
Storage mysteries
I don't know, if it's a bug or a feature, but there have been done serious changes to storages' permissions. It's probably an effect of allowing convertion of external SD Card, to internal memory. But let us start from the begginig...
When you'll first boot to the system, you will be asked, if you want to keep your SD Card memory as mass storage device or if you want to format it as internal memory.
1. If you won't format
Apps will be only able to use the internal memory. They will have no permissions to change anything or write to SD Card. It means, that you won't be able to download files to it or even manage it with file manager (even if it will have root permissions!).
You will be able to access internal and external memories from TWRP.
2. If you will format
You won't have access to old internal memory from system (practically it will disapeare), but instead you will gain full access to your SD Card.
Internal and external memories will be still available through TWRP.
Remember to make a backup to your PC, before formatting ;P
TWRP
You will have to flash TWRP 3.0.0 to get full access to SD Card after formatting.

Super SU
If for some reasons you don't want to use build-in root (for example I really don't like this hash sign on the statusbar), here's what you do:
1. Turn OFF build-in root in Developer Settings (if you don't, you'll get bootloop)
2. Flash Super SU through TWRP with the flashable ZIP from the Official thread (don't use Super SU App for this!) http://forum.xda-developers.com/showthread.php?t=1538053
3. When you boot to system, Super SU with root will be ready.
4. Reboot again to fix the Super SU app (it can crash)
XPosed
XPosed works with official version for SDK 23 arm.

SELinux
If you want to change it from enforced to permissive, look here

Release information
ROM is being developed on two channels: Nightlies with everyday (beta) updates, and with Release channel (with more stable versions).
Changelog can be found here http://www.cmxlog.com/13/g2m/
If you want to change channel from Nightly to Release - here's the official information what to do:
Update scenario 3: CM 13.0 nightly user
Update steps: Stop. Step away from the phone. Do not flash these builds, you are already on a newer codebase (Android 6.0.1_r22). Attempting to flash these release builds will result in crashes due to attempted database downgrades. Don’t do it.
If you want to swap off nightlies and stick to our release channel, you will have to wipe to take these builds.
