Root Galaxy S5 SM-G900F on Android 5.0 Lollipop with CF-Auto-Root

Root Galaxy S5 SM-G900F on Android 5.0 Lollipop with CF-Auto-Root
I updated from 4.4.2 rooted to the newest 5.0 this Post but is lost my root i Try this one and it works fine und was easy. Now my device are rooted , before i do this steps i installed mobile odin and i Checked the butten Auto Restart because it didn´t restart.
Using the CF-Auto-Root file by XDA developer Chainfire, you can root the European variant of Galaxy S5 (SM-G900F), which recently received Android 5.0 Lollipop stock firmware upgrade with build G900FXXU1BNL2.
The CF-Auto-Root is meant to be used in combination with stock Samsung firmwares and considered as the quickest and easiest way of rooting Android powered devices.
If you have already installed Android 5.0 on your Galaxy S5 and now wish to gain root access, check out the following root method.
Key notes
Ensure that you have installed necessary USB drivers for Galaxy S5
Enable USB Debugging Mode on phone to connect it with the computer and use Android SDK with it. [Navigate to Settings>> About phone>> tap Build number seven times. A pop up will appear, that reads, 'You are now a developer.' Go back to the Developer options and check USB debugging and click OK.]
As the tutorial is likely to wipe out all data of the phone, create a backup using custom recovery
Check the battery percentage of the phone, it should be at least 80%
Rooting the device will void the manufacturer's warranty
The CF-Auto-Root file works on with Galaxy S5 SM-G900F and flashing this on any incorrect variant might brick the device. Check the model number of the phone by navigating to Settings>> About device>> Model number
IBTimes UK will not be held liable for any damage to the device

CF root works with G900F on Android 5.0
Hi guys,
I tried to use CF autoroot to do the thing on my g900f. Seemed like it worked, but when I was reading the recovery (when installing root kit) i noticed "restoring files", "unmounting system" and I had a bad feeling about it. It was right. After phone rebooted I saw SuperSU app but when I launched it it said "Super SU binary is not installed and superSU can not install it..." and there was no root access... Then I decided to downgrade it to 4.2.2, but first I installed TWRP recovery, rebooted a phone and the root which I did before started working without any problem. So, Before using CF-Autoroot, make sure you have installed TWRP latest recovery. A lot of tutorials online didn't mention it. So my G900F on android 5.0 is fully rooted.

After I flash TWRP with Odin, I reboot into recovery, but it still boots the stock android recovery and now I'm stuck

Well, I have no indication of why you think you booted into recovery...what are you stuck in, ODIN screens? Get out of that by just having ODIN get the PIT and reboot.
Relay relevant error messages/workaround failures if you are stuck...

I fixed the problem. After flashing the TWRP with Odin, I removed the battery and booted straight into recovery mode instead of booting normally first. The reason is because Android automatically replaced TWRP when I booted normally, before I could boot into TWRP.

This TWRP i not used for Samsung s5 Neo s903f because i see Samsung s5 s900 versions phones and not s5 neo version. I gonna look where Google hiden stuff for s903f phone

[ROOT] SM-T707A - Lollipop with SuperSu - Xposed & Debloated - Part I

Root SM-T707A on Lollipop with SuperSu - Xposed & Debloated - Part I
The purpose of this thread is to provide several guides (written by myself) to achieve the following on the SM-T707A tablet:
* Part I: Flash Stock Lollipop 5.0.2 <---- YOU ARE HERE!
* Part II: Gain Root access for Lollipop with SuperSU.
* Part III: Flash Xposed Framework thru Flashfire.
* Part IV: Debloat the tablet from both AT&T and most of Samsung stuff.
* Part V: Improve usability and aspect with Xposed Modules.
But first, some words of our sponsors: NO, I'm NOT resposible for any consequence originated from the use of this guide, being that the death of your tablet, your phone, North Korea launching a nuclear strike or the Sixers winning the Larry O'Brien Trophy. Whatever happens to your tablet, it's ON YOU.
Introduction (recommended reading - not mandatory):
Four weeks ago I managed to capture this tablet for a very decent price on eBay. After buying an HTC 10, my bank account was in ashes and I was growing impatient with my unstable iPad mini 2. I wanted to live the full android experience on a tablet, while spending a mere $ 150.00. Buying a Pixel C was clearly out of the question. So, after some research, the T707A had the 8 cores, 3gb of RAM and also the AWS LTE neeeded for my country (Uruguay). Perfect match!
I was already drooling about installing CM and all the stuff to take this beast to the next level. With the tablet in my hands, just 5 minutes of -late- XDA reading made me realize that...CM wasn't happening (Locked BL). The consolation prize was to root the tablet with the infamous kingoroot and use Xposed to eviscerate as much bloat and touchwiz as possible. Sadly, that same kingoroot paired with a not-so-good battery life and the inability to use xposed almost put me back on the market for another tablet.
But...(there's always one) last monday, after several weeks of failures, there was a breakthru. SuperSU was breathing. Minutes later, Xposed modules where flying off the shelves and suddenly, the T707A was back into the game with more speed and less touchwiz feel. Since most of my objectives were met on Monday, if AT&T releases MM and someone helps us pulling that, I would love to achieve the same over MM. But, what didn't worked in this case (updating a rooted device), will have to in MM to manage the same results. At least we can enjoy lollipop in the meantime.
Part I: Flashing Stock Lollipop
If you're standing on Kitkat or, in Lollipop but messed too much with the system and want a fresh start, over the following lines we'll comment on the process of flashing stock kitkat (with odin), and afterwards applying the OTA zip files to reach Lollipop. We can't flash straight to Lollipop because we don't have the firmware for that. So, if you're already on Lollipop and only want SuperSU root, you can use my next guide BUT I STRONGLY SUGGEST you to flash kitkat first and update to lollipop with this guide to raise your sucess chances. Remember that doing that you are going to lose all your files, the flashing process ERASES EVERYTHING. So please BACKUP!
You'll need to download the following files, have an external MicroSD card (on your tablet), a PC and a microUSB cable.
* Odin 3.09
* BL file
* AP file
* CP file
* CSC file
* Update.zip
* Update2.zip
For Odin to work properly, you might need the Samsung USB drivers. Chances are you already have them installed in place. You'll know that in a minute.
Flashing KitKat 4.4.2 with Odin
Extract the Odin.zip in some handy place. Also, move the BL,AP,CP and CSC files to the same folder where Odin was extracted. Last, copy the Update.zip and Update2.zip to your EXTERNAL MicroSD card that's mounted on your tablet.
With your tablet disconnected from the USB cable, open Odin3 v3.09.exe.
We have to put the tablet in Download Mode. Make sure the tablet was turned OFF first. Now press and mantain the HOME and VOL DOWN buttons and then press the POWER button. All 3 buttons at the same time until the screen turns on with a Warning!! message. Now release the 3 buttons and just press the VOL UP to access download mode.
The Android robot will appear with the legend "Downloading...Do not turn off target!!".
Connect the USB cable to your computer and tablet. If done correctly, the Odin screen will show this legend below ID:COM:
"0:[COM1]" (the numbers on this legend are not relevant, and may differ).
If 0:[COM1] appears below ID:COM, we are good! If not, you have to try installing the Samsung USB drivers, or changing the USB port on your computer (use rear ports please!).
The last part of this segment is to choose the 4 files we have copied to our Odin folder. You have to select them on the Odin screen on the right "Files (Download)".
Hit the BL button and select the BL file. Do the same for the other 3 files. BE PATIENT!. After selecting every file, do not touch anything else until Odin shows the route of the file to the right of the button you pressed. The AP button may take up to 20 seconds to display the route after choosing the AP file.
The 4 files are set, so you just hit START and wait for 6 minutes. By the end, you'll have stock KitKat, and your tablet will show you the Samsung first use wizard. PLEASE don't touch anything during those 6 minutes!!!. A green "PASS!" will show in ODIN when its finished.
Flashing the OTAs for Lollipop 5.0.2
The tablet will boot and show Samsung first use wizard. Disconnect your USB cable and power OFF the tablet. Now we have to access Recovery Mode. Hold the HOME and VOL UP buttons and press the POWER button. When the GALAXY TAB logo appears, release only the POWER button while maintaining the VOL UP and HOME buttons pressed.
You're faced with Recovery Mode. Using VOL DOWN, move the cursor and highlight "apply update from external storage" and press the POWER button. Now move the cursor again to highlight "Update.zip" and press the POWER button. This will flash the first update file. When finished, the tablet will reboot itself. That will take you again to the Samsung first use wizard, so once more power OFF the tablet.
We need to enter "Recovery Mode" again (HOME + VOL UP + POWER). And again we have to apply an "update from external storage" but this we do apply file Update2.zip. Now Lollipop is being flashed. Ignore any error that might appear in red letters on your tablet.
After yet another automatic reboot, the tablet will boot the Samsung Wizard but now in Lollipop. Before putting your fingers on the display, PLEASE don't conect to your WiFi or use Internet over your Data Plan. Remove your simcard and don't use your Wifi until I tell you.
Now that you know that, head to our second guide to continue (here).
Special Thanks:
* @frizzdizzle27 for providing both KitKat and Lollipop firmware/files. He was/is key for us SM-T707A users.

Part 4 and 5
I followed your tutorial and it worked perfectly for my Galaxy Tab S. I was hoping to see an update on the Xposed modules and debloating...do you have any updates you can share? thanks in advance.

Anyone able to find the marshmallow ota?

Downgrading from Nougat

I goofed and updated my Verizon Galaxy S6 Edge (32gb) to Nougat. I'd like to attempt downgrading it back to 6.01 (Marshmellow?) I'm new to modifying my cell phone and would like to outline what I think I should do, and hopefully someone with experience will catch any goofs before they occur.
General Information:
G925V
Build # G925VVRS4DQD1
Hardware # G925V.04
1. Downloaded Samsung Switch, backup everything I can. This step should also place the samsung usb drivers on my pc? (window 10 64bit)
2. Prepare phone? Little foggy on this step, some guides recommended factory restore and erase cache partion first. Remove Sim card.
3. Download firmware from sammobile, I downloaded G925VVRS4CQA3, newest available 6.01. Does it matter that the last four digits don't match the last four of my Build #?
4. Put phone in download mode (reboot, home+power+volume down, volume up to accept)
5. Open Odin (v3.12.5) verify .tar file. I saw the AP file that needs pulled over, guessing there might be other files, firmware download still going.
6. Connect phone, check connection in upper left window of Odin hit start and don't unplug anything
7. When Odin finishes, reboot phone into Recovery mode, select factory reset all user data?
Am I overlooking anything major?
Thanks,
Cole

1.) From http://www.samsung.com/us/support/smart-switch-support/#!/faqs "The first time you connect your Samsung device to your computer, it will automatically locate and install the necessary drivers. (This process can take a few minutes to complete.) After the drivers are installed, the device will appear in the Smart Switch application.
If the drivers do not install automatically, go to the Samsung Support site and visit your device's support page. Click Manuals & Downloads to download the drivers for your device."
2.) Yeah, I am guessing prepare phone means prepare for total data loss (lol) when you perform a wipe data/factory reset from the recovery mode/menu (which formats /data, /cache and /sbfs partitions).
3.) The last 4 digits are different because you are on the first build of Nougat now (DQD1).
I have no experience with Odin myself, but I do know there are checkboxes, options and such you should do research on beforehand. For example, on sammobile's download page there are instructions saying "Make sure re-partition is NOT ticked" so just saying as there may be special procedures involved specifically when downgrading.
Another potential problem: have you found confirmation that you can downgrade -directly to- the last Marshmallow 6.0.1 build available for this phone (CQA3) -from- Nougat 7.0 (DQD1) and are you sure about it? There is a chance you may need to downgrade to an earlier build first.
Also I've had a strange experience with sammobile, as I downloaded the Nougat firmware for this phone and it is -completely- different (name, size, hash, modified date far before the public release) from other Nougat firmware I downloaded.
I recommend for any firmware build you decide to use: download from multiple sources and compare/verify with HashMyFiles or similar software to make sure it is really what they say it is.
I am awaiting response from a question for this OP; you should check it out as he mentions downgrading and provides download links (note: CQA3 is -not- in the list). https://forum.xda-developers.com/ve...25vvrs4dqd1-odin-nougat-7-0-firmware-t3597591

It worked. I did end up with a bootloop bouncing between the Verizon Screen and the Samsung screen that caused a few grey hairs. Eventually I was able to get into Recovery mode and performing data and cache resets allowed me to power on fully. I had performed a cache reset before starting the downgrade process, but not a data/factory reset. I also had the sim card removed. Either of those might have contributed to the bootloop. First action after google and Samsung account login was running BK Package Disabler and blocking the two sdm packages to hopefully prevent Nougat notifications (process contributed by @wolferno ).
Some information if it helps:
*Odin version was 3.12.5.
*Firmware version was G925VVRS4CQA3_G925VVZW4CQA3_VZW from sammobile (highest 6.01)
Backup was through Smart Switch, to get it running again I had to activate Developer options, enable USB Debugging, and under USB options enable MTP.
Hope this helps!

I have successfully downgraded from Nougat on my G925V 64gb
I used the stock software G925VVRS4CQA3_VZW4CQA3_VZW_USA_Verizon_6.0.1.
I downloaded from AndroidFileHost did the md5 check
It did boot-loop between Verizon and Samsung
Pressing and holding the Volume-down then Power button brought up the Factory reset (DOS-like) screen where I could do another factory reset to get the phone to boot up into setting up the phone starting with logging into the Samsung account.
I had activated another phone before this process so I could still get and make calls if it bricked, I've signed into my Gmail account that I have all apps and setting's saved.
I will be installing a Package Disabler as soon as the apps finish loading and before I activate the phone back onto Verizon.
Much thanks to coleauden for answering a PM and blkt for clarifying with coleauden earlier!!!
Enjoy the Day,
David

Pressing and holding the Volume-down then Power button brought up the Factory reset (DOS-like) screen where I could do another factory reset to get the phone to boot up into setting up the phone starting with logging into the Samsung account.
I had activated another phone before this process so I could still get and make calls if it bricked, I've signed into my Gmail account that I have all apps and setting's saved.
I will be installing a Package Disabler as soon as the apps finish loading and before I activate the phone back onto Verizon.
Much thanks to coleauden for answering a PM and blkt for clarifying with coleauden earlier!!!
Enjoy the Day,
David

Nice, I didn't realize CQA3 was on AndroidFileHost as well. Which Odin version did you use? Did you remove your sim card? BTW, I think you meant Home/Volume Up/Power for recovery mode (the DOS-like menu) because volume down would put you into download mode. In recent months there have been reports (on google play reviews) of Package Disabler Pro removing the ability to disable certain packages at the request of Samsung (removed from package list, no changelog either). Maybe this has changed; I have not investigated further but there's also BK Package Disabler. Here is a helpful page with all Odin versions. http://www.droidviews.com/download-odin-tool-for-samsung-galaxy-devices-all-versions/

Maintenance Boot Mode is what I get into with holding Down volume and holding Power button.
Odin 3.12.5
De-activated SIM still in the phone (activated a iphone for calls)
I ended up buying BK Package Disabler to block the OS upgrade/update.

Oh wow, another mode I was not aware of. Thanks! This one is good to know because it is apparently accessed when the phone is still on. Confusing though, because I though volume down + power was to force reboot. The recovery mode I mentioned is done after the phone is off.

Sorry I didn't clarify......
I pressed the 2 buttons once the phone was off...
In all the times I have ever had to get into the lower (Root) areas of the phone , I've started with the phone off so I assumed this was a known practice.
Apologies

Oh, I thought you used it to get out of the boot loop. No worries, as this video put my brain through a boot loop. https://www.youtube.com/watch?v=9N5Q8RD5QPs

You should be able to downgrade to any firmware that is Revision/Binary 4.
You started with 4DQD1 right?
You should be able to downgrade to any firmware with like 4A, 4B, 4C, 4D, etc.
