hi, I'll been looking through the forum for hours and was unable to really understand how to execute my issues. Therefore i have to create this threat to asking for help out of no choice ( I rooted my phone 2 month ago using zergrush method and recently I wanted to upgrade my busybox and I uninstall it before reinstall a newer version, but when I am uninstalling busybox, It stopped half way and say there's some program that stop it from uninstall fully, and then my root access couldn be granted to my busybox anymore and it couldn be install back to my xperia play again. so do my Titanium backup couldn get the root access from SU. but others root access software remain ok. I reformatted my SD card and phone hoping to get rid of the error but my system apps(screen locker, silence mode) is GONE! and the root remain in my phone but my preinstalled data gone. I decided to do a flash to reset everything but Im scared and unsure. any pros please do advise whjat should I be doing on this issues? thanks in advance.
These are the steps I took 10 times so far:
1.Do a clean flash of 2.3.2
2.Root your phone with Gingerbreak
3.OTA to 2.3.4
All Fixed!
4.Restore all your apps with titanium(if you didnt delete backups)
5.Install CWM for locked bootloaders
6.Do a Nand Backup if your phone is working correctly and save it to your PC
BTW just download busybox installer from the market and you dont have to uninstall it before update,just launch the app!

Or you could flash the proper Cwm for unlocked bootloader if it is unlocked. Don't think you need to be unlocked to flash official roms

So ive been doing a lot of reading on rooting phones and the best way to go about doing this, but I still have a few questions about the whole process. First IM going to briefly write what I understand about the process and have it corrected and then ask my questions.
To root:
I will follow this guide http://forums.androidcentral.com/ve...ock-bootloader-root-verizon-galaxy-nexus.html
Basically I will make sure all drivers are updated on my computer (samsung and USB)
Use command prompt to unlock the boot loader and then install superboot for the GN
after this process is done and I reboot the phone I will be unlocked and ready to go
Modding
Done through CWM
1. I will download the mod that I want and place it in my phones internal memory.
2. boot into recovery mode with CWM
3. backup the phone with CWM (can anyone tell me where the back up is saved)
4. factory reset the phone
5. install zip from SD card (which will be the mod)
6. reboot back into recovery mode and install Gapps that I downloaded from the cryogen mod wiki through the "install zip from SD card" option. http://wiki.cyanogenmod.com/index.php?title=Latest_Version
7. Reboot phone and i will be good to go
SO my questions:
1. If i missed anything, can you guys quote my steps and add in what i left out in the correct order?
2. How do I update the phone to 4.0.4. If im guessing correctly, I would rename the file to update.zip, and before i modded my phone and after the factory reset I would install that zip onto the phone? I'm just slightly confused on the process
3. How do I uninstall a mod and go back to stock
4. How do I handle OTA updates? I know that with mods, I cant download the OTA automatically. I would guess i would have to uninstall the mod, download and install the update, and then thats where I dont know what to do
5. Is there a way to back up all my apps so when I install a mod or update a mod I can just have them all reinstalled back in and have all the settings restored, without having to download each individual app and change their settings back to what they were previously?
these are all the questions that come to mind presently. Some may arise later.
Thanks in advance, and if some of my questions have already been answered in a previous thread, can you guys just post a link to that thread?

You have it correct. Use titanium backup to save all your app data. And you have to restore a nand backup if you want to undo a mod you flashed. The mod usually instructs you to backup right before flashing, so you can just revert right back if you want.
I wouldn't worry about ota anymore. Being rooted always leads to you being able to flash the latest ota quicker than if you were stock and waiting for your number to be called. Trust me after years of this that's how it always happens.

There are some things that don't make sense in what you are doing.
1) Yes, you install the correct drivers;
2) Yes, you unlock your bootloader; however, if you want to save any data, it would be better if you root first (before unlocking your bootloader) -- see link in my sig, backup apps/etc. and even do a full backup. Don't forget to copy all of that OFF your device, as unlocking wipes even /sdcard.
3) If you are going to install a custom ROM, then there is no need to root the stock ROM you currently have, only to overwrite it with a custom ROM. Doesn't make sense.
4) If you are installing a custom ROM, you cannot "update" it to 4.0.4, unless the dev releases a 4.0.4 update for that particular ROM.
5) If you are sticking with the stock ROM, look at the link in my sig for either how to update to 4.0.4, or, better yet since you are unlocking your bootloader (which will wipe all your data anyway), flash the full 4.0.4 ROM.
6) OTA updates are only for stock ROMs.
7) You can use Titanium Backup once you are rooted to back up apps and app data.

What's the difference between a stock rom and a custom rom? I was looking at milestone 4. What is an example of a stock rom because I would prefer that to be able to still do ota updates.

If you are asking that question, more reading is likely in order before you start flashing things.
But anyway: a stock ROM is the ROM Google puts out. They are found here, and instructions on how to flash are in my signature. All other ROMs are custom ROMs.
Gotcha. Ill look it up tonight

I ended up reading more which lead to me unlocking and installing 4.0.4
Im happy with this now and I dont feel the need to custom mod. I need my phone to be functional all the time with out being too time consuming =D thanks for the help and leading me to my conclusion
I would seriously give aokp a try, I promise its worth it. Its the same as stock there's no extra work needed or anything to worry about or deal with. Its that good.
Id say stick with stock. I tried all the custom roms and while customisation options are good, nothing better than knowing your phone is 100 percent stable and secure with a locked bootloader.

I wouldn't recommend re-locking your bootloader if you have unlocked it. Actually, I would recommend that, every time you buy a Nexus device, the first thing you should do is unlock the bootloader. Don't forget, having an unlocked bootloader does not mean you are not "stock". An unlocked bootloader doesn't affect anything (aside from what I mentioned below).
Why you ask? Good question:
Advantages of a locked bootloader
If you lose your device, no one can easily access your data, but only if, in addition to your bootloader being locked, you have the stock recovery installed AND you have USB Debugging disabled AND you have a password on your device. However, this "risk" (if you can call it that) can be mitigated by many apps that can remotely wipe your device.
Disadvantages of a locked bootloader
You cannot use fastboot commands, so you cannot flash or boot images, which can save your butt in certain occasions.
You cannot try out new radios (assuming no root).
You cannot backup your data (i.e., make an image of your device's memory (assuming no root).
You cannot root (on 4.0.4 and later).
You cannot manually update to the latest version of Android once Google starts rolling it out. You have to wait until Google decides it's your turn, which could be minutes to months after the update becomes available.
+1 to working without me thinking. I'm leaving the boot loader unlocked to install any updates Verizon doesn't push through but other than that its staying stock. Plus I really like vanilla ICS AS IT IS

IDK if this is ever an issue for new users but When I search I never find the exact thing I wish to know but much close to it.
In all My 16GB phone as of yesterday with no media or installed apps my phone had only 1 GB free and the filesystem was full of folders from old apps. I had installed and uninstalled many apps and flashed many roms, Which I believe left many leftover files. So I was told to format the System Partition and either restore or install a new rom. Since my latest nandroid was ICS based I decided to start fresh (also to clear up as much space I could.
My question now is, I still have many extra files from uninstalled apps. My phone now has 6.8GB of the available 11.8GB according to Windows 7.
So to completely START CLEAN what is the best method? (I will have a nandorid backup and a rom to install both on my pc and on my External SD Card)
Using CWMR,
Format System, Then Format SdCard? Then the Steps Required to install The Specific ROM you will now install.
Is the SdCard partition the usable space? If it is then the System Partition Contains all System Files and leftovers from flashing Roms and Kernels? If that is correct then Is the SdCard Partition basically the Users Space for apps and Media and what Shows up on the PC and The user Directory once Rooted?
Is this The Best way to do it? I have Seen Superwipe although have not found a page specifically about it. I have found versions of the script for many devices. Since their seems to be one available for the Samsung GS3 should i just flash that (I see it on the page for installation of the Xquizit Rom) and on an older post for another device said that it would "wipe /boot /data /system /cache and /devlog" then it says your phone is ready to install the rom (on the page i forget the rom or device it was for).
So to Clean my phone to the point that it is as close to possible as being new and this is the first rom to be installed and the first apps to be installed, when i install apps.
To accomplish this Should I? Use CWMR and manually format the system and the sd card partitions? or use the Superwipe script from the Xquizit Rom page?
Lastly but Most Importantly to use Superwipe do I simply just flash the zip? Also if i do it manually Have i described the correct way to do it?
Last of all Thank you and Sorry Its I just have never done this and as i still haven't even paid off my phone I don't want to Brick this phone at ALL.
Since this post has no reply's but some views that means i either asked a question that either A. has been asked and answered and i have not found it. or B. This is something that is so easy its never really been an issue.
If its A. Could someone be kind and just link to a post, or post the correct search term as I have been unable to find it.
If its B. Then to close this will I have a problem formatting the SD-card the same way I formatted the system partition
Also is their a Superwipe how to? and does it do what i think it does (basically format your hole phone in one easy step by running a script via your recovery mod?
I just don't want to brick this phone when it comes to formatting it just scares me for the first time.
Use the Odin software for a clean install. It wipes partitions, radio's everything. You can choose to intall a rooted Tmo update with Odin so that way you are ready to go. Just flash CWM with Rom manager after using Odin and you are ready to flash any rom you want.
See this thread.

Will Odin even replace custom recovery and radio with the stock recovery and radio? Or must that be done manually?

Yes ODIN will replace everything. I suggest using the pre-rooted route66 file for ODIN in Doc's thread I referenced above. It saves a step.

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?

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.
Following the somewhat dispersed advice in this forum, I managed to use Towelroot to root my TabPro 8.4 SM-T325 w/o tripping KNOX. As soon as I'd done so, a new OTA update became available, which I'd like to get, and then re-root my tablet, again, all w/o tripping KNOX. Based on what I've read in this forum, the following SHOULD work:
1. Unroot with SuperSU
2. Reboot
3. Check for persistent root access by trying to run Titanium Backup (which won't run w/o root) - Root Checker failed to confirm root on my SM-T325 for some reason though I DO have root, so I don't expect Root Checker to be any use in confirming unrooted status
4. Flash latest stock (from SAMMOBILE) ROM (dated later than my present one) via ODIN
5. Reboot the device in Recovery Mode (Home + Power + Volume Up)
6. Do a wipe data/factory reset.
7. Hope that does the trick
8. Replace kernel w Towelroot-compatible kernel
9. Run Towel root
10. Restore kernel extracted from latest stock ROM
Are any steps missing from the above? Can any be safely omitted? I'd love to avoid the factory reset, but understand that can't be avoided when using ODIN to replace the ROM, even when the replacement is the latest stock ROM. Is that true? Or is the factory reset a precaution to avoid trouble? Or used to get out of it? When I did OTA updates before rooting, a factory reset was never necessary, and since I'm STILL running a factory ROM (rooted), I am wondering if I can safely omit the factory reset.
Thanks.
