Hey guys
I am completely new in this topic. I just got an Samsung Galaxy Tab S (SMT700 Wifi) as a present a few days ago. Its my first android device I had so far.... so everyone will call me "noob" and I am okay with it DD
When I realised that there are different android os development projects like CM and Paranoid, I become interested in trying them out. so...
1.) Is it possible to brick the android device completely or is there something like an recovery/dfu mode in iOS devices?
2.) Can I go back to the stock OS contributed bey samsung itself (Touchwiz Kitkat)? If yes are this files online?
3.) Does I need special hardware to perform a custom rom flash? (micros card/special OS on pc (linux,....)
4.) Does the CM blck mod in the official forums contains alle required drivers and blobs already to perform gpu tasks and so on? (are there currently downsides swell?)
Thx :fingers-crossed:

1. There is bootloops but hardbricks are rare. You can enter recovery and download mode(flash stock rom on broke os) in a bootloop. Just hold power, home or vol up for recovery and home +power +vol down for download mode.
2. Yes you can go back to any version of stock os unlike apple you have to be on the latest. The files are online for your device at sammobile. (google it) and also samsung updates.
3. All you need to perform a custom rom flash is a custom recovery called twrp and your device. Theres an app on google play for installation of it. (search on youtube on how to do so). But thats just flashing zip based roms(which most custom roms are). For stock rom installation, you will need a pc and a application called odin 309 to flash a stock md5 file rom in which you will need to be in download mode (like installing new update from itunes).
You will need to backup your whole rom with twrp before flashing a custom rom. You may need a micro sd if your short on space. You will also need to be rooted to install custom roms. Please go to the cfautoroot thread of your device to root your device in which you will viod warrenty.
4. Cm rom as of now still has bugs but is still useable for games and such. There should be a list of bugs on the thread and might have some missing features such as ir blaster and finger print scanner. Battery life may vary. So there are downsides.
5. I can go into more depth of custom stuff and flashing if you wish. Right now my fingers hurts xD. Hope this helps!
1) it is very, very unlikely even if you try intentionally to do so
2) yes, no problem. google for Samsung Firwares, it's all online
3) windows PC, Odin Software, and an USB cable, that's all. You can do it with Linux if you prefer. Some Roms are installed via zip file from the device itself, then you need to flash a new Recovery partition first, that is able to do so
4) ?
Thx you very much for the help !
After reading a lot about this topic it seems to be not as difficult as I thought it would be.
But I don't get one thing. Why does I need to make a proper backup only for the flashing propos? If I flash my internal memory, all data will be replaced. And if it goes wrong I will be able to do a complet software reset with odin and the original samsung image found in the Internet?! So why I have to make a backup (there is no data in my current tap I will need in the future)?
And does the cf chain root flash the OS or the firmware ?
As my understanding tell me that the firmware is something comparable to a bios , which should never be flashed to maintain stability.
So as my logic goes further if my device is rooted, after a proper reset it will not be rooted anymore? (Android stock reset function in settings)
Or does armbased devices not have a normal firmware/bios as I mentioned ? And something in the bootprocess itself is manipulated to anable root access?
Hopefully you get what i mean :angel:

1. Sometimes odin and kies will fail for you. Twrp backups is to be really safe if you get bootlooped and odin fails for you. Its much easyer to restore a twrp backup and easy to make one. Its just if odin or kies fails which twrpnwould be your only hope. Just in case
2. Cfautoroot only flashes supersu and root. It keeps your apps and everything. So when you flash cfautoroot, it will say andriod is upgrading becuase its installing root and restoring back your apps.
3. After a full proper reset, it will not have root and revert back to stock. Thats where you flash cfautoroot to gain root again!
Hope this helps!
So as of now I managed to root my device and also created a twrc backup, which is now transfered to my sd card
Are there major differences between a rom flash with twrc recovery or odin?

Most custom roms are to be flashed with twrp. Meanwhile stock roms/md5 is to be flashed with odin(firmware from website).
Again Thx you very much!! You are awesome!
I managed to install cyanogenmod its insanely fast compared to the touchwiz version
But there is one more thing I have to ask.
I installed TWR in the latest version but the klimwifi (2.8.XX) version (klimtwifixx was not avaible). Is this the right version?
Where exactly does TWR be installed. Afther the wipe and the format it stays, so I have no clue how it can be available even if the internel memory was formated?
I started TWR by the terminal (reboot recovery), becouse I have no clue how to start it instead by button pressing?
And there are no playstore how can i get it on cm11?

2.8 is the latest version of twrp. I dont think your device is klimwifixx. It should be klimwifi. What the wipe and and factory reset in twrp does is that it clears all your apps and wipe cache. It does not wipe any folders and it justs wipes your apps. So internal should not be affected unless you formatted it... You just need to swipe the factory reset on it when installing roms. For google play store you have to flash a file name gapps. There should be a link to it on the thread. To get into recovery, turn off your device, then hold power, home, vol up buttons at the same time to enter recovery. To exit recover just touch the reboot rectangle and hit reboot system. Hope this helps!
Okay now its clear TWRP replace the "downloade mode", which is the standard recoverymode
You said I do not need to format the disk, but why?
In linux distributions (debian for example) you will have similliar structure for example /var /bin /sbin /usr /proc,.....
If there is the stock touchwiz android it will have this structure listed above as well. So it will courrupt the os by overwriting this folders by a custom rom....
. Maybe you wont do it in the TWRP menue, because it will do it automatically by choose you custom rom install script in the zip?
How is the portioning in those devices? Maybe there are /dev/sda1 (android) and /dev/sda2 (with the recovery setup inside)....? I just want to understand those things

No no! Twrp replaces stock recovery. Download mode cannot be replaced. You enter it by holding power, vol down, home button when the device is off. Download mode is when you flash things. Recovery mode is when you clear cache or other stuffs. I have no idea with the linux stuff you explained but custom zip roms just adds some modifications and other stuff to the device. You would need to clear cache and factory reset so you wont have problems installing it. You can easyly go back to stock rooted by restoreing a backup you made in twrp. It has to do something with img and replacing those if thats what your talking about idk. No need to format as the rom add things to it. Just need to factory reset and cleae caches.
But now if I want to enter download mode for testing, it will boot into the twrp recovery. So as for me it looks like that it is already replaced..

It shouldnt be as twrp only replaces recovery. Img did you try doing home, power, vol down?
Hi
I have a quick question I have the Galaxy tab S 10.5 wifi and was wondering can I install TWRP without the tablet being rooted?
Also there are some builds where it states that its rooted, debloated and de-knocked. Does this mean that they can be flashed without rooting the tablet and tripping knox.
Thanks for your replies, still trying to get my head around this.
I apologize up front if this is posted in the wrong section.
The threads I have been reading have all come from this area.
I have a BLU Studio HD 651u that is rooted.
Somewhere along the way of rooting and tweaking and what not, I managed to make a terrible mess of things with my phone.
I have a backup copy of the Stock rom for my device, and what I would like to do is install a custom recovery, then completely wipe my phone. COMPLETELY! (if that's possible), then, flash the stock rom back onto it.
I am hoping that flashing the stock rom doesn't 'unroot' my phone. I would like to keep that. It was quite an ordeal getting it rooted to begin with, and I believe the cause of some of the problems I am having.
The Stock rom files I have are not a zip file, so I would need guidance on that procedure as well.
I found links to the stock rom from the g+ pages for my device. There were 2 links. The one contains rom files for all the BLU devices, but the second link provided I'm not sure I even need.
If someone would care to take a look, here's what I'm talking about. My device has MT6585

https://mega.co.nz/#F!TplRURRI!LyAuAlNIBND_AOgu3bx6tQ
And the recovery tutorial I found here
http://forum.xda-developers.com/showthread.php?t=2668712
I am pretty much a complete noob. I only have experience with one Android device, a Kindle Fire 1st gen. that I was able to root, but not without seeking help from the fine folks at this website.
I am hoping to strike luck again???...
I don't know if I should try installing the stock rom and then try to install a recovery or should I attempt to install the recovery first and then install the rom?
And at which point should I attempt to erase EVERYTHING on the phone?
I did look for a section on XDA for my device, but, there isn't one I could find, and like I said, the recovery tutorial was found in this sexction so I am hoping not to offend..
Any help/input/comments or suggestions is greatly appreciated.
Thanks!
This link --> https://mega.co.nz/#F!TplRURRI!LyAuAlNIBND_AOgu3bx6tQ is a public folder for BLU stock roms, just go to the folder STUDIO SERIES -> Right click in this folder -> STUDIO 6HD D651U and select: Download as ZIP
In this folder -> https://mega.co.nz/#F!W9AUGAQR!a6xLckX4_CqABLKUrh8iYA, download both files and follow this guide to install the driver and flash the rom,
I recommend to hard reset the phone before or after flash a ROM, even if you dont hard reset you will not have root
After flash the stock rom you can root and install custom recovery
The only way to format the phone it's when you can't install stock roms and SP Flash Tool keep showing errors, so format the phone and try again, it should solve (in some cases) some SPFT errors
I'm already on the stock KK ROM (E98020g)., but with the CWM recovery. I just want to wipe everything while keeping the stock ROM, but I've seen that factory resetting or flashing stock ROMs while on a custom recovery will probably cause a some sort of brick...
I've already briefly seen the pinned stock ROM tutorial already. Before I try that (assuming it still works), can anyone tell me if there's a simpler way? It's going to take me a long time to go through that entire thread so it would be an immense help if someone could just tell me.
Have you try using system setting, storage, hard reset?

That's what I meant by "factory reset", sorry. Everything I've read indicates that this will cause a softbrick, which I'm trying to avoid. Is this info wrong?
I assume the reason that you install cwm and running the stock ROM is so you can have a nandroid backup? Otherwise Why else would you installed a custom recovery? So backup the ROM and do the factory reset with kk instead of cwm, which may be the reason that some people are getting the soft bricks. I can't guarantee you that everything will be according to the plan, but that's the reason backup function is there.
I originally installed CWM because I wanted to wipe and try out a custom ROM (probably CM). But then I noticed all the serious issues people were having with various custom ROMs, so I decided to skip the custom rom (for now) and just get on with wiping. I really don't want to risk any type of brick with this device.
Anyway, I think I'm going to try out the pinned stock rom thread I mentioned in the OP.
Was on 4.4.2 stock NJ2...Odin'ed a custom recovery like TWRP...rebooted.....NO IMEI and BASEBAND. That's about as simple, yet complex it gets. Tried reverting back to stock recovery in Odin, only to find that NO IMEI and BASEBAND still shows up. THE ONLY way I've successfully kept the IMEI/BASEBAND....is by keeping everything stock, from recovery to rom. Why would this be? I've even tried restoring the EFS folder....to no avail!!!! I'M FRUSTRATED!!!! My end goal is to be able to flash a rom, use TWRP/CWM, and KEEP the IMEI/BASEBAND!!!
ANY HELP? ANYONE having the same issue or fix?
THANKS!!!!!!:good:
Possible fix...
Make sure you have not used device encryption on the rom prior to your desired rom...
If you have then a device full wipe script is needed to clean up the phone prior to flashing the new rom...
(don't forget to check your SD card for encryption or data files that may be affected)...
Flash TWRP version 2.8.6.0 and flash your new rom....
Higher TWRP versions have been buggy for me...
Best I've got atm....g
It's because you are using TWRP 3.0.0.1, that one is broken
Other than the nice graphical interface, is there any reason to install TWRP if all one needs to do is flash a ROM? The stock recovery allows you to wipe the cache and do a factory reset as well as flash ROMs. I have used both on other devices. I recently bought a Tab S 8.4 and plan to install LineageOS 14.1. Seems like the stock recovery will do what I need without having to use Odin.
Update: I've done a little more reading and it appears that I probably cannot flash a custom ROM from the stock recovery. I had assumed that was possible due to the menu item of "install zip from SD card" item. I this is correct, then clearly I'll need TWRP to flash a custom ROM. If anyone can verify this, then the thread can be closed.
I like TWRP because now and then I can do a full backup of my install. If you tend to mod your ROM with root in any way, this can be handy because you can always revert to the old setup.
I like cwm recovery much better
