(Q) Lost root and custom Recovery !! i9505 - Galaxy S 4 Q&A, Help & Troubleshooting

hi all.
I'm really struggling here and dont know what to do.
Ive been rooted and have been running EchoeRom 4.4.2 with an Alucard kernel thats been brilliant.
Last week i seemed to have lost a load of apps - which in hindsight were some that i had moved to SD card. I couldnt update the apps, reinstall or reinstall via titanium.
Long story short I used mybackup after reflashing the ROM but started getting some f/c
A factory reset didnt help so I decided to unroot and flash stock 4.3 NG8 firmware then re-root through ODIN. This is something I/ve done before - but now it wont work.
Ive tried CF Autoroot but the Superuser app says missing Binary.
If I try to get to recovery it just reboots again after 2 seconds to normal startup. I have tried just flashing CWM and TWRP recoveries both with auto reboot checked then un-checked with a battery pull about 20 times.
On 2 or 3 occasions I've had the CF red splash screen for rooting, but that seems to finish with a 'restoring stock recovery' message and i'm back to square one after it reboots.
Ive tried a different superuser app but it couldnt update the binary.
I even attempted a different rooting method with Towelroot but after accessing the APK it starts phone not supported.
Im really stumped now and have no root and no access to any recovery. If i could get to recovery Id be ok.
I dont know if ive destroyed root forever - when updating on ODIN I usually get a PASS message so i suspect something bootloader related may be overwriting the installed recovery ?
Any clues folks !!

1. Reflash android 4.4.2 GN8 firmware through ODIN
2. Download this FILE and copy it to your phone (in SDCard better)
3. Go to DOWNLOAD MODE and Flash TWRP (for example) through ODIN.
4. Remember the combination for go TWRP is a lil difficult and sometimes your phone will reboot normally. This happend to me too:
- Power off your device completely.
- Press and hold Volume Up, Home and Power buttons simultaneously.
- Release the buttons when the phone’s screen flickers or the TWRP Recovery logo blue appears.
- That is it, after you release buttons, you will be taken to the main Recovery Mode menu..
5. Install the file of the step 2 with TWRP.
6. Done

sorry for delay in responding.
I was about to follow your advice, when at random when using the phone it flashed up a message..
something along the lines of 'unauthorised activity detected - reboot phone'
I did this only to go straight into Philz recovery and since then have been able to load a backup, reflash a new rom and all seems ok.
Very strange !
Thanks for the help though.

[Q] Flashing 4.3plus then Freezing

My Tegra Note 7 came with Android 4.2. I unlocked, rooted, and installed CWM via the instructional videos over at rootjunky.com. Then through CWM I installed De-Odexed Stock Rooted 4.3plus from this thread: http://forum.xda-developers.com/showthread.php?t=2627671
Once the install finished and I rebooted the device (the reboot took maybe 30-45 seconds) I came to the setup "Welcome" screen. It is here that the Tegra Note froze. I thought it may be because it takes upwards of ten minutes for the first boot to complete/install but 30 minutes later the screen is still frozen.
When I do a hard reboot a few times I'm able to make it through the welcome and setup screens and the device appears to work just fine. I'll be able to install apps, run the stylus software, etc but then every 5 or 6 minutes (maybe shorter, maybe longer) the device freezes again and I must do another hard reboot. This happens repeatedly. And I still can't use the device for more than a few minutes.
Any ideas/suggestions?

I was able to finally fix mine and stop the freezing and locking up. What I had to eventually do was reflash the stock 4.2.2 image, reflash the stock recovery and then update as usual OTA and now I have an updated EVGA TN7 fully functional. Thankfully this forum helped a lot by having the resources needed to fix the issue.

How did you flash the 4.2.2 image and the stock recovery?

Have to get into the bootloader which for some reason mine is still just a blank black screen even though it says it's unlocked. I used a program called Quick Boot which is mentioned in one of the tut videos, it took a while because of the freezing but once I had it installed I used it to boot back into recovery and bootloader. I did this because the method of holding down power and vol up was not working.
I also noticed that as long as you are moving the screen around with your finger on any screen it would not lock up. I used this to transfer the stock image and recovery over from my computer using the usb.
Once in bootloader you use fastboot to flash. ex. fastboot flash recovery stock_recovery.img from the windows cmd prompt.
I had CWM recovery flashed when this first started so I used Quick Boot to go into recovery to flash the stock 4.2.2 image first to even see if it would help the freezing and once it did I went back and did the above to flash stock recovery so I could let the tablet update using OTA updates.

From where did you get the 4.2.2 image that you can flash from stock recovery? I have a problem of getting the 4.3+ installed since I flashed the CWM recovery. I tried flashing a stock recovery but failed every time. My question is, would flashing an earlier ROM such 4.2.2 enable me to get the 4.3+ update or do I still have to flash a stock recovery?
Got the same error after flashing 4.3 or 4.4.2 manually (since OTA halts with an error).
How to get rid of it?
Thanks!
4.3/4.4 crash. I fixed mine finally! 4.4 working great, no crashing!

I had the exact same problem as you... I finally got it working, up to date with 4.4 CWM recovery, rooted and sd card fix. All working great... but here's some history...
I had the same bootloader that never worked from Power on/Vol Up, but would work after an adb reboot into fastboot. (blank screen only)
I was on stock 4.2.2, then unlocked bootloader, then updated to 4.4 using Supertool 2.2, Root, Sd card fix, but stock recovery still. All installed fine, but I had the crashing problem. Factory reset, and reinstall.. didn't solve the problem.
So I went back to 4.2.2 using the "temp" cwm recovery (using the root option to get in the cwm recovery, but I flashed the 4.2.2 file from root junky web page instead of rooting)
So here I was at 4.2.2 stock (from rootjunky web site), and stock recovery. Still not bootloader screen from Power.Vol up.
4.3 OTA would not work (dead droid with red triangle,error),
So I used supertool 1.5, installed CWM recovery, then I installed 4.3. It worked and rooted automatically, but I still got the crashing, and no bootloader by Power/VolUP. 4.4 OTA wouldn't work even when I put stock recovery back.
Here's where I got it to work from 4.3 stock (with crashing still happening, blank bootloader):
So now I used Supertool 2.2 to flash its version of CWM recovery (I had to keep touching the screen to keep it from crashing until CWM was installed and rebooted).
I did NOT use Supertool 2.2 to flash 4.4 as it contains the OTA 2.1 with it!!! (We don't want that yet! You'll se why below) I copied the 4.4 file at rootjunky: "Stock-4.4.2-TegraNote7.zip, February 22nd 2014 460 MB" onto the internal sd card (NOT the external sd card)
I used adb commands to reboot tablet into cwm recovery (had to keep touching screen until it rebooted into recovery so it wouldn't crash). Then I flashed the above 4.4 file. Install went fine. Of course I I still had crashing with 4.4 stock again. However, I noticed that the OTA 2.1 update appeared! I tried to update, but of course it wouldn't with CWM installed. So I reflashed recovery back to stock using supertool 2.2
Guess what happened next? The OTA 2.1 downloaded, flashed and worked! This was the first time I was ever able to get ANY OTA update to work! The key was to flash a stock 4.4 that didn't contain the OTA 2.1, and have stock recovery (from supertool 2.2) first in order to allow the OTA 2.1 to install!
Guess what works now? 4.4 works with NO CRASHING! and my bootloader finally works by holding Vol Up and Power ON and fully function menus,etc..!!! The tablet runs beautiful! The 4.4 had no root, or sd card fix applied, and stock recovery, but it DID lock the bootloader!
So now I used supertool 2.2 to unlock the bootloader (which I could now do because my bootloader had working menus, and could be accessed by Power/Vol Up). Keep in mind that this does a factory reset and wipes user data. (I had not wiped ANY user data right from 4.3 up until now!)
After the bootloader unlock/factory reset, I then used supertool 2.2 to: install CWM recovery, install root, install sd card fix.
Now I have an EVGA Tegra Note 7 with a fully functional bootloader, 4.4 Kit Kat, CWM recovery, root, sd card fix. All running great with NO crashing!
This is what worked for me... proceed with caution and know what your are doing first. Good luck!

@TerryRed:
You saved my bacon! I was having a similar issue with a totally borked root attempt... I was frustrated with repeated attempts to recover from the freezing issue. I followed your instructions and recovered the Tegra. Like you, I discovered that if I continually the device active by tapping and moving the screen, I could use the device. My idle limit was about 5 seconds, though.
In a nut shell, and while pretending to be a poor excuse for DJ 'scratching' (or do they call them 'controllerists' now?) I:
* Made sure ADB Debugging was enabled
* Copied the 'Stock-4.4.2-TegraNote7.zip' archive to the device's internal storage
* Ran SuperTool 2.2 and ONLY flashed the stock recovery
* Rebooted
[Resume silly DJ motions, while frantically setting up WIFI]
* Checked for, and downloaded the OTA update manually [OTA FOUND!!!]
* Waited the agonizing 10 second countdown for the device to initialize the installation
* Let Android do it's thing
!! SUCCESS !!
Thank you, and all of the guys here at XDA who donate their time, talent, and valuable info that help us mere muggles free our devices and take them to new heights.

So yours bricked as well???
I had the same problems:
- Bootloader not working as expected (only black screen).
- After CWM and flashed 4.3 constantly freezing.
- OTA not working (it said something like "This is not Tegra Note, it is Tegra Tab")
So being desperate I flashed a deodex 4.3 from RootJunky's web.
Since then tablet in boot-loop and still no way to get into Recovery.
I can only access APX mode, but I am not sure, how to use it.
Any help appreciated.

So, to fix the boot loop it is as simple as it can be. I can't believe I didn't find that earlier. (BTW I didn't find a clear answer in the forum until today, thanks to hacktrix2006)
Just download the NVflash and the image mentioned in post #2 in following thread. Follow the instructions to switch tablet into APX mode, install the driver and start the flashing. Flawlessly done. No problem. Got rid of the Chinese OS (not supporting Google).
Really cool!
Just in case anyone still has these issues I'm going to post how I found a way to resolve them. I had all the problems mentioned in the previous posts and more besides. The inability to apply OTA updates, the device would freeze after 5 seconds of inactivity, endless boot loops, failed recovery partitions etc etc etc.
I tried a butt load of different solutions but none worked for me. What did work is described below. Others have already mentioned that Advent has a stock rom recovery utility, however, even after flashing that my problems still remained. So I downloaded the Advent stock recovery util and documentation and modified it slightly to the latest Android release for the Tegra Note 7.
Do as follows:
1 - Go here and download both the Advent Vega Tegra Note Factory Image (4.3) util and the documentation.
2 - Extract the Advent Factory Image zip file (as described in the documentation) somewhere on your pc.
3 - Inside the extracted folder you'll see a bunch of files. The three files we're interested in are the "recovery.img", "system.img" and "boot.img". Select all three and delete them.
4 - Now download the Tegra Super Tool utility here. At the time of this post the latest version is 2.5.
5 - Extract the downloaded Supertool to a new folder on your pc.
6 - Inside the extracted folder there are another bunch of files. Again, we're only interested in three of them. You're going to rename three of the files and use them to replace the three files you deleted earlier. At present their names are "4.4.2-2.5recovery.img", "4.4.2-2.5boot.img" and "4.4.2-2.5system.img.ext4". The filenames will obviously change as time goes by, but a little common sense goes a long way at this stage. So "4.4.2-2.5recovery.img" is renamed to "recovery.img", " 4.4.2-2.5boot.img" is renamed to "boot.img" and "4.4.2-2.5system.img.ext4" is renamed to "system.img". Once you've renamed them, copy them into the folder for the Advent Vega Tegra Note Factory Image which you extracted in step 2.
7 - Now go and read the documentation for the Advent Vega Tegra Note Factory Image util. Just take your time and follow it to the letter. It'll tell you how to put your Tegra Note 7 into it's APX mode, install windows drivers for it and begin the recovery of your device. It's mostly an automated procedure and fairly simple to follow as long as you follow the documentation.
This method brought my Tegra Note 7 back when it had several of the problems mentioned earlier in this thread, all at the same time.
Hope it helps someone.

[Q] Need help with restoring normal boot on Samsung A3

Hi everyone!
This is my first post, hope there is a solution.
I have Samsung Galaxy A3 [A300FU].
I wanted to get rid of branded firmware, so I've found stock ROM here: mrcrab.net/stockrom/sm-a300fu.html and flash it with Odin and it was ok.
Then I wanted root, so I've followed this guide: trueandroid.com/root-samsung-galaxy-a3-sm-a300f-easy-guide and now, whenever I restart the phone, it boots to the screen with yellow text: set warranty bit : recovery (file_1.jpg). Then it goes to the screen with opened green robot (file_2.jpg) and after I choose: reboot system now, it loads to OS normally.
How to fix it?
Ok guys, I don't know what happened, but I've managed to save the day
What I did was connecting my phone to KIES and select Firmware Update and Initialization from the Tools menu. It wipes all the data so be prepare for that. This helped to get rid of the yellow text on the screen while booting, but the phone still kept booting to the recovery mode.
Then I've installed TriangleAway from this thread: forum.xda-developers.com/galaxy-s2/orig-development/2014-01-15-triangleaway-v3-26-t1494114 but it didn't seems to work (and, by the way, it doesn't support my phone). I've also installed SuperSU from Play Store, and also didn't work, so I've uninstalled both and reboot the phone. And guess what - it booted normally, straight to the OS.
Magic.
Sooo, the solution I've provided above wasn't what I needed, because I insist to have my device rooted. That's why I started once again.
I've installed stock ROM, rooted it and the result was the same (yellow text and booting through recovery mode).
I've customized the build with 360 Security (there's many apps out there which allow uninstalling system software and bloatware). Then I've installed Team Win Recovery Project through Odin meant for Samsung Alpha (teamw.in/project/twrp2) and that was it. No more yellow text or booting to the recovery mode. Shiny clean rooted A3.

Ive been itching to root and install a custom rom seeing the stovk is starting to slow down a A LOT! Could you help me out by guiding me through the bloatware removal as i dont want to uninstall something i shouldn't

You flashed a custom recovery meant for Galaxy Alpha on Galaxy A3? Doesn't doing that bricks the device? I'm having the same problem too.

Ok, here are the steps:
Download the newest formware from sammobile and install it through Odin.
Turn off the phone and boot into recovery, wipe cache and run factory reset. I don't know if it's meaningful, but I did it and that's it.
Set up the device and turn on USB Debugging in Developer options. To make those options appear you have to open Settings, then About Phone and keep tapping on Build Number.
Download root files for your model from here: autoroot.chainfire.eu, run Odin, install it and turn on the phone.
I assume you'll get those messages like I did "Set warranty bit : recovery" and the phone will keep booting into recovery mode and from there you can boot into OS. But it's unconvenient, so I've download the TWRP files to get rid of it. At first I used files for Alpha but last time I've install recovery meant for S4 Qualcomm and it worked as well (here: twrp.me/devices/samsunggalaxys4internationalqualcomm.html).
It didn't brick my phone. It keeps going. I don't know much about devices so I didn't hesitate I just wanted root for Macrodroid
Oh and I have SD Maid to freeze unwanted apps, like preinstalled ones and those I don't use, like android e-mail app (I prefer Gmail), stock calendar S Planner (I have Sunrise, it syncs with iCal), KNOX, live wallpapers, some widgets, Fliboard, S Voice, Google Movies Music Games Newsstand Books Hangouts, Google+, Hancom Office.

I like what you did!. Is the TWRP 2.80 or twrp2 for Samsung Alpha working in Samsung A3? I mean to say that if you go to recovery by pressing Vol Up _Power _ Home Butttons, does TWRP Recovery appears? Or the stock recovery appears and you solve only the recovery and yellow problem?
If the TWRP Recovery Appears then you can install custom roms, backup your system and data. This will be a great job done by you and many owners of Samsung A3 will be thankful to you. Please Reply because I want to test it on my mobile

Well, it seems it only solved yellow text and can't boot into recovery at all. It can't be that way! So!
I've installed unbranded software once again and was waiting to update to Lollipop via Kies. But it took so long that I couldn't resist to root, but I did it differently this time. I've found KingRoot app which works like a charm. Just download the apk [mmgr.myapp.com/myapp/Kingroot/webapp_kingroot/image/KingRoot-4.1.0.249-release-nolog-201505211812_105001.apk] from [kingroot.net/down#root], run it and voila! No hassle, no Odin. After rooting there will come up two apps: Kinguser and some app in Asian. I've uninstalled the second one - it cleans memory and stuff. Stock recovery stays untouched and booting is normal.
Hi Everyone!
I Hope There Is a Solution....
I have galaxy a500g running with stock lollipop and I need to install a custom rom so I flashed TWRP_2.8_SM-A500-LL.img and booted into recovery once it booted into recovery it struck at set warranty bit:recovery and struck at recovery loop....is there a way to install a working custom recovery for galaxy a500g
Thanks in advance

Having trouble rooting, flashing, and changing kernels

Is there a way to clone a device?
I have two Samsung S5's, and one of them is running GREAT. The other one, not so much.
In lieu of cloning, i'd like to have some help figuring out what i'm doing wrong in this process:
I rooted the phone, installed Plasma ROM 2.0, and debloated. I lost the ability to rotate the screen, and I finally did something about it.
I returned the phone to stock, and attempted to root and install Plasma just as before.
I'm using the root instructions (below), and i've run into one of three issues:
1) When I run towelroot, it says this device is not supported.
2) When I am able to get towelroot to run, the phone boot hangs after step 7, install NI2 Stock Kernel.
BY boot hang, I mean that the startup screen appears (Samsung), and then it just stays there. I don't see any action, and it doesn't respond to any buttons.
I'm using ODIN 3.07
I'm running Windows 7 Pro 64 Bit
I've got a couple of different cables, and haven't had any issues with that connection.
ROOT STEPS:
1: Download the RootS5.zip file and unzip it to your desktop.
2: Copy tr_v2.apk, BusyBox.apk, Safestrap-G900V-3.75-KitKat.apk and UPDATE-SuperSU-v2.46.zip to your extSd card on your phone.
3: Run Odin3 and load G900V_NCG_Stock_Kernel.tar.md5 in the AP slot.
4: Shut your phone off and enter download mode by holding down the power, home and volume down buttons until it boots to download mode and then press the volume up key.
5: While in download mode connect your phone to your PC and Odin should say you are connected. Now press the start button to flash G900V_NCG_Stock_Kernel.tar.md5 to your phone. The phone will now reboot and update some apps, let it finish. After this there will be a bunch of force closes. Just close them until they go away.
6: Open your file browser, go to tour extSD, install and run tr_v2.apk, BusyBox.apk and then Safestrap-G900V-3.75-KitKat.apk in that order.
7: Shut down the phone, enter download mode again, flash NI2_stock_kernel.tar.md5 and reboot into safestrap.
8: While in safestrap install UPDATE-SuperSU-v2.46.zip from your extSD card and reboot.
If all went well you should be on the NI2 firmware, rooted and safestrap installed. For those who do not want to install safestrap you can skip those steps and update superSU from the playsotre.
You mentioned that you flash back to stock, what firmware version did you flash?

Currently what is your status? Do you have safestrap installed? what firmware running? rooted?
CURRENT STATUS:
Phone hangs on Verizon screen.
Alright, I finally came back to this issue.
I ran a factory reset/data wipe from recovery menu, and now I can boot into the device.
Current status is in photo.
I found this post: http://forum.xda-developers.com/showthread.php?t=2784880
and im downloading this file to use: ALL_VZW_G900VVRU1ANCG_G900VVZW1ANCG_964333_REV00_user_low_ship_MULTI_CERT.zip
My goal right now is just to get this phone back to bare stock, and then root it, eventually getting it to match my other S5 (which is still running great!)
Any reason this won't work?
Alright all, here's the outcome.
I followed the directions at this link: http://forum.xda-developers.com/showthread.php?t=2784880, and now I have a working phone.
I then installed Plasma ROM 2.0, using the directions on that post, and now i'm working on making it my own.
All in all, success!

I did everything as you said. I pulled out the battery after flashing TWRP, but when I tried to go to recovery menu. My phone keeps getting stuck at the 'Samsung GALAXY Note 4' logo and there's a red message in the top left corner that says, "RECOVERY IS NOT SEANDROID ENFORCING."

When you flash twrp. Untick auto reboot. Let it flash, till it is complete. Unplug. Pull battery. Put back in. Then immediately reboot into recovery by holding pwr+vol up+home
Plus use the new Twrp

Download SuperSU zip files here!
Use Pc to install Odin and use Odin to install TWRP.
Then copy Supersu to phones SD card. And use TWRP to install it.
All done!
