[Q] HELP with installing TWRP - AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin

Hi,
Long story short. I had TWRP 2.5.0.2 with my SGH-I377 (Galaxy S4 AT&T). I used it to flash this GE ROM by Maddog (http://forum.xda-developers.com/showthread.php?t=2340783)
After flashing, the ROM works just fine without issue. The Model Number in the about phone section however showed to be GT-I9505G, but I didn't mind too much since it works flawlessly in everyway. When I tried to update TWRP to 2.6.3.0, GooManager downloaded the wrong img due to this (it was my fault for not looking at the version before clicking yes). But now after reboot, i can't get into TWRP recovery anymore, it keeps saying "System software not authorized by ATT has been found on your phone". I was able to bypass by going to download mode and cancel to boot back into my old GE ROM. But now I can't seem to find away to get the correct TWRP version back on the phone.
I can download the correct img from this site, put it on my internal/ext SD, but I can't find a way to install it from within GooManager or from a File Manager.
http://techerrata.com/browse/twrp2/jflteatt
I need some assistance with instructions on how to install TWRP manually from an img file. Or from a tar file using ODIN if anyone has the link to necessary files and instructions on how to do it. At this point, it doesn't even have to be 2.6.3.0, I'll be just happy to get 2.5.2.0 back.

You won't be able to install it with Goo Manager. Head over the the TWRP website and find your phone that way, and grab the flashing zip file and just flash it in recovery. I had the same issue a few weeks ago.

After some more digging, I was able to find a solution.
For anyone who runs into this problem...I was able to use Quick Flasher from this thread http://forum.xda-developers.com/showthread.php?t=1694617 , then choose the flash a new recovery using the correct TWRP img
Everything is good now, I am able to get into TWRP recovery 2.6.3.0

That's straight from the horses mouth there. I didn't read much into it, but it looks like they have a odin flashable version. Also make sure that the newest version of TWRP doesn't conflict with the ROM your using. I have read quite a few where the latest version causes issues.

Question About Software Error Message

Hi guys. Not new to rooting but new to my AT&T S4. I rooted it tonight with Motochopper and installed CWM recovery. Downloaded and tried to flash a ROM, and it simply didn't work. Then I tried Beanstalk 4.2.2, and it downloads, but then when I rebooted it, it gave me the yellow triangle unauthorized software message. So I pulled the battery and finally got it to boot into recovery, then installed the back up I had from the stock OS. My question is two fold-what's causing this and if I download a ROM with the Loki patch, will that bypass the error message I'm getting. I searched the forums but am not understanding what was written. I'm pretty confused, any help would be greatly appreciated.

So, to sum up development in this forum for the last 3 months: The ATT version of the S4 has a locked bootloader, which is a fancy way of saying ATT and Samsung don't want custom software on their phone partitions. To keep people from installing custom ROMs, their bootloader requires a verified signature present in the ROM to actually allow the device to boot.
An individual found a way to trick this verification process, and created a patch for it called LOKI.
When a ROM is "Loki'd" it contains this workaround for the verification process in the bootloader, allowing custom software to be installed.
To answer your question, when you root your phone and install the recovery (TWRP or OUDHS): a ROM must be lokied to work. OUDHS recovery has a feature which automatically installs the workaround in every ROM you flash using the utility. I recommend this version of Clockwork Recovery.
The link is here:
http://forum.xda-developers.com/showthread.php?t=2291956
I personally use the nightly CyanogenMod 10.1 builds for the ATT S4 (called jlteatt). They're quick and stable except for a few quirks with the camera, call-audio via headsets, and bluetooth audio.
The link to download is here:
http://get.cm/?device=jflteatt
*This version of CM 10.1 is already Loki'd
Have fun flashing, and if all else fails and you accidentally run into a scenario where you can't boot your phone, use this utility to restore the factory OS that comes with the phone.

OK, thanks very much. So I was indeed on the right track. I'll try your ROM recommendation as well as the modified CWM recovery.

Install twrp on G935P

I am having an issue trying to download twrp on my sprint edge 7. I cannot find the right directions to download the recovery. I have rooted the phone but cannot get twrp to install. Please i could use some help. I thought i got it but when i go into recovery it gives me the security error. Any help?
To my knowledge, twrp isn't available for our devices yet, and due to how tightly locked down the bootloader is, we may not get it. Not even sure where you'd have found a download link for it unless you flashed twrp for a different device
So we cannot flash roms on the sprint 7edge?

Root, recovery and custom rom setup for Galaxy S5 (SM-G900I)

Hi all,
How are you?
I've been looking at these forums for most of the day, though am still quite confused. If someone could assist to clarify it would be much appreciated (as I would like to avoid to brick my phone).
I'm currently running Stock Android, Marshmallow version 6.0.1 with the 1 November 2016 Security Patch.
The model of my phone SM-G900I (Australian edition).
So I've come across the following links with the instructions on how to root and install recovery, though quite confusing.
http://forum.xda-developers.com/show....php?t=2699648
Recovery Query?
I understand that you need to download the Samsung Drivers and Odin.
I've downloaded the TWRP files for my phone - twrp-3.0.2-2-klte.img.tar and twrp-3.0.2-2-klte.img.tar.asc
Do I need to use the twrp-3.0.2-2-klte.img.tar.asc file at all?
Root Query
Is the towelroot method of rooting the S5 still relevant. The reason I ask, is that when I had posted an initial question on the XDA assist, I was advised that this may not work.
If the towelroot method is no longer relevant, would the CF-Autoroot method below work?
http://forum.xda-developers.com/show....php?t=2696537
If neither of the above methods work I have seen mentions of "flashing root" via TWRP.
Are there any known instructions on how to do that on XDA or any other website?
Or is it just a matter of obtaining the superSU zip file from https://download.chainfire.eu/696/supersu/ and flashing it?
The other information seems straight forward re using the Samsung Tool to backing up the device and the EFS .
Any help would be much appreciated.
Thank you.
just flash the .img file in download mode, and dont use the asc file at all. also dont use twrp 3.0.2-2, just use 3.0.2 (not 3.0.2-1 or 3.0.2-2 as they can be pretty buggy). Towelroot has long since become irrelevant back in the 5.0 days unfortunately so all you need to do is find the appropriate supersu.zip file and put it on your phones sd card (either internal or external), boot into recovery an install that zip via TWRP then reboot. Should be good to go. The classic "root via recovery" method

1. Plug in your phone and let the drivers load.
If phone unrecognized then head to Playstore you can find loads of apps for drivers
2.unplug your phone and turn it off
3.Load odin.
Some versions of Odin are outdated. So watch for that.
4.Holding your turned off phone. Hold the volume down power and home buttons. Done correctly it should bring you to a page saying custom Roms can damage your blah blah. Volume up to continue down to reboot. Plug your phone in then Push volume up if you feel ready to Join us Oh Padawan.
Now I am sorry for the lengthy information, most likely you have already gotten to this point, but I just want to make the same page for you and future readers. No point in asking a bunch of potentially irrelevant questions when one explanation is sufficient.
5. Odin should find your phone which will be represented by a lit up colored square on the left side indicating a Com:value# which number is of little consequence just tells you which port it found it at. Do not dwell on this.
6. Using an extraction program such as .7z take your CF auto root .Tar file, not the .Asc, and extract. You should be able to find an file with ap in the extension.
7.Take the path from the URL bar of this window including the name of the ap file and copy it over to Odin. In Odin you will see the place to put it is represented by AP.
8. CLICK START AND WAIT WITH JEOPARDY MUSIC.
9. IT MAY REBOOT A FEW TIMES BUT UNTIL IT SAYS success OR FAIL IN ODIN DO NOT TOUCH.
10. Repeat steps 7-9 for twrp.img
10. Now taking this was a success turn your phone off. Unplug and holding volume UP power and home Gets you into twrp recovery. If all is well you can reboot into system. Ignore the kernel warning.
^^^^^ theres the long explanation LoL ^^^^^^^^ i disagree with step 9, but meh
Hi all,
Thanks for the detailed instructions.
So it appears that you can perform the task in 2 ways, ie
* By initially flashing TWRP first using Odin (whilst phone is in download mode), then running the TWRP and then copying over the supersu file to the sd card, then flashing this.
Or alternatively, following the above steps which first
* roots the phone by using Odin within download mode and the "cf auto root" file. Then once again using odin and flashing the TWRP file via odin.
This is my understanding.
Please let me know if I've misunderstood, otherwise thanks all. I'll be giving it a try soon.
My eventual goal is to install the Resurrection Remix Rom, so fingers crossed.

the cf auto root file usually isnt necessary, nor is flashing supersu really as the newer twrps have the root function built right in. Itll ask you if you want to enable superuser rights the first time you boot into it. Just swipe right and its rooted. Alternatively, flashing supersu from within twrp or the cf auto root also work. CF is the acronym for the dev ChainFire, he is the man (or she, and conversely "the woman" or whatever LOL)!! But the crux of what you need is twrp installed, from there youre usually set. Get rooted, make a nand of your stock setup and flash away. Also, id make sure to download the stock tar.md5 file of your phones firmware in case all goes awry (or to hell in a handbasket or enter clever euphemism for stuff going bad here) so you can flash the stock tarball in Odin if you get stuck in an endless bootloop and your stock restore file doesnt work. Also, when resoring from AOSP to TouchWiz or vice versa, does require a few boxes to be checked for it to work, but it happens all the time. Happy flashing and feel free to ask away if you run into anything man!
Thanks all for clarifying.
I did have some difficulties along the way though I did successfully install twrp.
So I downloaded one of the latest versions of odin on mums computer. Laiche the twrp tar file in the ap section. Loaded it then restarted the device. Ran recovery though it was still the default android recovery ie it appeared as though nothing had changed. I looked at another forum which suggested to turn ooff the auto reboot option in odin and perform a battery pull and then launch directly into twrp. This actually worked after much agony.
I then loaded a superuser zip and flashed it onto the phone.
Rebooted confirmed that the phone was rooted.
I then relaunched the twrp recovery and ran a nand? backup of my device. Then I attempted to install a custom rom ie resurrection remix. Unfortunately it did load though the screen appeared to freeze after boot and was therefore unusable. Thank goodness the restoring of the backup worked.
I'll reattempt the installation of a custom rom very soon. Fingers crossed.
Thanks.

Rooted, Custom Rom a huge fail

Hello dear Community!
It is depressing that my first appearance here is to ask for help, but I am going crazy.
So, I tried to Root my phone via Odin + CF Autoroot klte and it seemed to have been a success.
The root checker also said, that my device was rooted so I went on and installed TWRP to be able to install Lineage OS.
After getting Lineage to work I got a few error messages suddenly popping up, telling me that either "Music had stopped" or other android operation were closed because they didn't work properly.
I tried to install Gapps, it seemed to have worked but I was only able to open and enter the store once, afterwards the store never managed to load and then the app closed itself after starting it.
So I checked again with Root Checker, but this time it gave me an error message, too. It said, that my device was not rooted properly.
I guess this is were I made it worse by deciding to just root the phone again. Obviously, it didn't work either.
Afterwards I thought that maybe installing The Original Android OS and then unrooting the phone would be the best solution to be able to start anew.
First I tried to flah Lineage again and that made it impossible for me to boot the phone. The farthest I got was the setup page, were it tells you Hello and were you can choose a Language, but clicking the arrow key didn't do anything at all.
The recovery mode was also not the TWRP one anymore, but the original Android one and that was a huge problem for me.
Then I tried to flash the 6.1 OS for the S5 (I made sure it was the correct version), but now it is stuck at the "Samsung" screen while it boots.
It never boots though.
I don't know what to do anymore.
Please, I beg you, could anyone help me out?
Don't flash the latest Lineage OS ROM

What are the grounds for your claims?
You needn't root via CF-autoroot if your end goal was to flash lineage. CF autoroot was intended to root stock roms with ease and less effort.
Flash The LATEST, official TWRP via odin then do a FULL WIPE. Wipe system, data, cache and dalvik cache.
From here on, you have two options:
1.) Sideload the LineageOS rom via ADB
2.) Transfer it to the phone's storage via MTP and flash it from TWRP.
As for how to accomplish this, the forum search bar and Google has your back. You need only choose one procedure.
If you need the Play Store, flash gapps AFTER flashing LINEAGE AND BEFORE REBOOTING.
Since you were under the idea that utilizing CF-autoroot was a necessity, I suggest that you re-read this post thoroughly before actually putting it into practice.

Thank you so much for your fast reply!
-> I flashed the newest Version for klte via Odin, but I can't get into the boot mode.
I only am able to enter the download mode. What can I do now?
Flash TWRP via odin again, untick the Auto-Reset option of Odin first. Then try booting to recovery via long holding the power, home and volume up button simultaneously without releasing any of the buttons until you successfully see the TWRP splash screen.
If that still doesn't work, reboot to recovery via adb from download mode. You need the adb and the usb drivers for your device.
If that still doesn't work, you might have flashed an incompatible version of TWRP.

Thank you so much, it worked perfectly!
I can now start my phone and use it normally.
But the Root Checker still says:
"Sorry! Root access is not properly installed on this device.
Device: SM-G900M
Android version: 7.1.2"
What should I do from now on?
Thank you so much for your help (agaiN).
And as for why I used the auto-root, well I just followed a guide that I found, it only had positive reviews so I assumed it was a correct tutorial.

I thought about doing that, but wasn't sure how exactly to proceed and what Version to install.
I downloaded SuperSU v.2.82 and put it on my internal storage.
Just install over TWRP the same way that I Installed Lineage and Gapps I suppose?
I guess if it doesn't work out, I just follow the steps from above again and retry?
Thank you so much. I feel like in idiot in this situation.

Error E3004 when trying to install any ROM on Samsung J5 (2015) SM-500FN

What I have:
I have a Samsung J5 (2015) SM-500FN which ran out of storage and basically hung itself up. There is no data I want to recover, but I want to install either a stock ROM or (preferably) something else like Lineage - I just want to get a usable phone again.
My problem:
I have tried to download *many* stock ROM
s from reputable sources like SamMobile (for this specific phone, but trying different release dates and country codes) but every single one of those ZIPs is corrupt, even when downloading from a different computer.
Flashing with ODIN anyway gives a FAIL result and a device that cannot boot, not even into recovery: It gives a green screen with the text: `An error has occurred while updating the device software. Use the Emergency recovery function in the Smart Switch PC software.`
Ironically, the Smart Switch software just says this device is not supported. The older Kies3 software lets me enter the exact model# followed by the serial# - but then it says this device is not supported. So neither Samsung software is usable, but I can still use ODIN.
Even with the phone in this broken state, I can install TWRP again. So it is not completely bricked. I boot into TWRP and copy a LineageOS ZIP file to /sdcard, but when I try to install that, the TRWP console says: `E3004: This package is for device j5nlte,j5nltexx; this device is .` Note how it doesn't appear to recognize that this device is indeed the model j5nlte!
Android.SE says that "E3004" means my TWRP is too old, but I use `twrp-3.1.1-1-j5nlte` which is currently the newest version for this phone.
I would also like to try a factory reset, but that requires the stock recovery which won't boot (see step 2 above).
My question: How do I get out of this catch-22?
It seems that if I could just get around that E3004 then I would be fine. But I have found no ways to trick the installer into ignoring that error.
Flash an updated twrp .IMG file which you can extract from the file here j5nlte (TWRP)
Just flash the img in twrp and reboot to recovery
Then with the updated twrp try flashing the rom again

THANK YOU! This did the trick. May I ask: what is the origin of that TRWP image? How could I have found that on my own?

No problem at all, glad all is working for you now. Happens all the time with people having the wrong recovery its no big deal but a lesson learned is always make a backup in twrp before going tinckering around with things or keep a copy of a rom, that you know works, on your SD card.
From the bootleggers pie rom thread.
The Dev of that also builds his own twrp for all j5 2015 models.
he's a really great guy to have supporting our j5 community
