Galaxy S8+ (G955U) bootloop - Android Q&A, Help & Troubleshooting

I switched to samsung from apple and i stupidly tried to flash some firmware without really knowing what i was getting into. I ended up getting my phone stuck on the ATT logo and only being able to get there and download mode, cant even turn it off.
I've googled, tried everything i can find, and used all sorts of combinations to no avail. I've gotten to the point that when the phone boots up, it shows the android man and says "no command". WHen i try and go into recovery mode from there it tells me that i dont have a recovery mode.
From what i've read the best step is to flash stock rom but i cant seem to get anything to work, and although i've been messing with this for a grand total of(probably over) 24 hours, im still as lost as i was in the beginning.
I've got Prince Comsey, Odin3 V3.12.3, Odin3 V3.12.7
With firmwares that APs are
AP_G955USQS3CRE2_CL13001792_QB18008668_REV01_user_low_ship_MULTI_CERT_meta.tar.md5
AP_G955USQS5CRI4_CL13889051_QB19733321_REV01_user_low_ship_MULTI_CERT_meta.tar

AP_G955USQU1AQC9_CL10895874_QB12856072_REV00_user_low_ship_MULTI_CERT_meta.tar
I've done the trick of, when starting the flash, rebooting the phone back into download and starting again. Which actually let odin flash some software(which is how i am now at the android "update" screen) but that was all it did.
Some software give me "Fail (Auth)"
Some say "complete write fail"
But none have worked.
EDIT: to add; I've eddited the configuration settings for all odins to be able to use the "UMS" option for the "USERDATA" file, which seemed to help odin but nonetheless still didnt fully help me.
Someone please help me get my phone working again. WHat else can i do?
Please also, if you have a solution or question, explain what you mean or need in detail because as i said i am very new to android

Could I get a bit of help with a relatively lame brick?

Wellp, I tried to install Cyanogenmod and it bricked the crap out of my phone. I followed their guide at http://wiki.cyanogenmod.com/wiki/Samsung_Vibrant:_Full_Update_Guide and got to the "The Samsung Vibrant now has ClockworkMod Recovery installed. Continue to the next section." step and upon my phone's startup (with the added Clockworkmod flash screen) was greeted with nothing but a black screen. All I see is the samsung "S," glowing for ten or so seconds, like the Windows logo, then it goes black. I tried One Click Unbrick (http://forum.xda-developers.com/showthread.php?t=1153310), which restarts my phone, and brings me back to the same screen. Next, I tried doing the three button (sound-up, sound-down, and power) boot into the Android System Recovery program. There, I deleted the cache data, all user data, and attempted to reinstall packages, but I got a "failed to verify whole-file signature" error, as well as a "signature verification failed" error. I also, tried to re-flash via ODIN, but the only way to get it to see the phone is to boot it to the S logo screen (and the darkness beyond). There is the no-man's-land that Odin detects. Unfortunately, Odin gets stuck at the connecting step, and goes no further (unless that takes more than a few minutes). Fun stuff.
I'm sure you get people asking for help all the time, so I am very sorry to be yet another person asking, but this is quite the frustrating brick.
I am able to boot into download mode, as well as the android recovery menu (the aforementioned area with clear cache, user data, etc.) so I have found a bit of solace in those facts.
Thank you so much for your time.

which rom did u come from?
Froyo. I followed the guide to a 't' and got this black screen. I have no idea what I did wrong.
Well, I need to run off to work now, but I'd really appreciate any responses.
It seems like my phone isn't being detected by odin or windows when it is in download mode, though windows does recognize that a Samsung USB device is being connected. This is recognized in the windows tray (under the name "Samsung_Android"), and in Heimdall's Zadig driver tool ("Samsung_Android").
Hmm first tthings first, your reinstall package error seems pretty simple, yu dont have the right update.zip and recovery combination... if u wanna solve that problem, find the recovery 3e to 2e tool (google it) and run it (follow directions).. then you can run reinstall packages (might havr tto do it twice). If that doesnt cut it, find the CWM update.zip and put iit into the root of your internal sd card (the 12gb one), then run reinstall packages again. You may have to reinstall packages more than once.
Your odin problem might be caused by a lack of drivers on your comp... go on the android dev section and look for a thread talking aboout ms64 and 86 drivers samsung something...
If you can get into download mode, you can unbrick your phone so dont panic
Now odin is a very dangerous tool imo so if you really are sorry about askint, do us a favir and read the sticky oon how to odin before you use it so you dont have to come back and ask us about how to Really unbrick your phone
Also, your brick is referred to as a soft brick and the android recovery program is referred to as recovery mode.
And if you really **** up, we now have the unbrickable mod in the vibrant android dev section which will unbrick your phone no matter wat (it takes somr hardware modifying though)
Sent from a cell tower to the XDA server to you.
And if i were you, id redownload the cm7 package again to make sure that it wasnt a bad download and id read some general vibrant info before diving into cm7... if youre running stock recov and have never odined before etc, youre prob not the best candidate for flashing.. just my opinion

Thank you very much for your reply. I couldn't find a related tool with the Google search string "3e to 2e recovery tool vibrant," but I did find a modified 3e tool at dkszone(*)net/bypass-e-signature-verification-fail-issue-on-samsung-vibrant-android-2.2 . However, this gets stuck at "checking for temporary root."
As for installing drivers, I have installed the Samsung galaxy 64 bit drivers several times now, but I'll give the 32 bit drivers a whirl as well.
I am unable to access the SD card, and don't have a mini SD card reader, so that compounds the problem (damn my lack of cash!).
*Edit* Upon my attempted installation of the 32 bit drivers I get the following (word for word) "Swallowtail has being used. You need to eject device and reboot your computer. Rerun (Japanese or Chinese characters) after reboot your computer." Google returns zero results when I search for this error. I tried rebooting my computer and running it again, but got the same error (even with the phone unplugged from the computer).
*Double Edit* I've been trying to use the AIO Vibrant Toolbox to restore my phone to factory defaults, but I've been having no luck, as it claims my phone is not in USB debugging mode (and obviously I can't change this, as I have no access to the Android OS).
Try this, mate and hopefully you will be up and running soon...

When I run this the program handshakes, downloads the pit file, then restarts and "...Local and device PIT files don't match and repartition wasn't specified!
Ending session...
Rebooting device...
Device not connected.."
It reboots to the black screen of death and stays there. Perhaps I could select "Flash Bootloader," but the warning of possible permanent damage scares me.
According to the thread...
"REPARTITIONING ISSUE WITH HEIMDALL 1.3.0
Heimdall currently has an issue with repartitioning. 99% of the time you will not need to repartition. Failure to follow these directions can possibly lead to bricking:
Do not flash bootloaders if you see this message:
Code:
Local and device PIT files don't match and repartition wasn't specified!
This message means your partition tables do not match the firmware."
So I guess one of the roots of my problem is that my partition tables do not match the firmware. I have no idea what to do about that.
In this case try another computer if you can, install the right drivers and see odin recognizes your phone. I'm sure it will, for some people sometimes it takes fair few tries for no reason.
Another suggestion, take out sim card and external sd while connecting in download mode. Sometimes that helps.

Here is a recent thread where someone had issue with odin connection.
http://forum.xda-developers.com/showthread.php?t=1225197#16797271
Well, I ran Heim one click on another computer and had the same boot-to-blackscreen process happen.
I was, however, successful at getting Odin to recognize the phone with AIO vibrant toolbox. Odin kept getting stuck at "set pit file" though.
Baby steps...
This is so frustrating. I feel like I'm so close.
How do I get the right PIT file on my phone if ODIN is getting stuck at that step?
Now, after installing the drivers provided with Heimdall-one-click's Zadig, ODIN doesn't recognize the phone.
One step forward, two steps back.
*Edit* Nevermind, got ODIN to recognize it again by uninstalling/reinstalling all related drivers.
Then odin to stock with tthe stock jfd files.. follow the manual, report results

Use those files and the procedure for ODIN.
As for what caused your problem. You flashed a clockwork recovery for a different phone, possibly the Vibrant (non-MTD) mode? Usually installing Clockwork on the Vibrant only works from ROM Manager app when its running stock JFD. At least for me anyway. Any other ROM it ****s it somehow and I end up in a situation like yours. Not to worry though. Here's a quick install guide after you ODIN the phone to stock.
Put latest nightly of CM7 on the phone memory (not external microSD)
Install clockwork (Easiest way to do this is put the update.zip file I've attached onto the root of your phone memory, not the external microsd card, then reboot into recovery (hold both volume buttons and turn it on) and select Reinstall packages twice. It will then boot you into Clockwork).
Wipe data and cache in clockwork
Install zip from SD card--> pick the latest CM7 nightly.
DONE.
I'd like to use those files, but every single link is broken...
*Edit* Never mind. Found another source. I'll post upon success/failure.
*Edit again* Actually, it doesn't seem like the new link on mediafire has all the files required by the process (OP: http://forum.xda-developers.com/showthread.php?t=734475), and I can't post in that thread (because I'm a new user).
This is the post that uploaded the files: http://forum.xda-developers.com/showpost.php?p=17512889&postcount=615
So I haven't changed a damn thing yet, and all that happens when I try to put the phone in download mode is | Phone----Warning (!) Sign----Computer | screen comes up.
Even when I only plug it into a power outlet...
Flashing the IPhone was easier and more stable than this, years ago. I honestly expected better from Google.
*Edit*
OH MY GOD. Odin is going somewhere! Go, AIO Vibrant Toolbox, Go!
*Edit again*
And it stopped at about 90% with "<ID:0/003> dbdata.rfs
<ID:0/003>
<ID:0/003> Complete(Write) operation failed.

Well, I tried again and everything finished uploading, and got the green "pass!" for the first time in Odin.
Now my poor little 959v is stuck in a booting loop. The Samsung Vibrant screen comes up, disappears, comes up again, disappears, ad infinitum.

959v is the not the vibrant, tis the galaxy s4g, if you odined vibrant files on your 4g then that's why you are in a bootloop
Dear god do I feel stupid. I googled it a while ago just to be sure, and it seemed to say that the V stood for "Vibrant." I guess that would be why I've been having this sneaking suspicion...
Well it's good news for you, mate. Head over to galaxy s 4g
forums and hopefully you will be able to get your phone back.

[Q] I9205 Recovery Flash?

I have an i9205 that I am trying to fix for somebody. The phone was acting weird so he rebooted it and did a battery pull. After doing so the phone would just sit on the samsung boot screen. I could boot into download mode, but if you went into recovery mode it just said installing update. It would get to 100% restart and then just sit on the samsung logo. Everytime you booted into recovery it would do this. I downloaded kies and tried to reflash the phone. during the flash an error popped up and said to retry in emergency mode. That also failed and phone said "sw rev check fail fused 1 binary 0" on the screen. I am thinking now the only option is probably to flash with odin, but was wondering if anyone else had any ideas. thank you
After flashing a lot of samsung phone, I think the best way to reflash is Odin. Try to download the firmware you want and flash it with Odin. And then, reboot. This always save my phones.
For your recovery, have you tried to update your phone with OTA ? The download may be incomplete and make a soft brick.
Sorry for bad english I'm french.
Thanks for the reply. ya thats what I am going to try. There are a ton firmwares based on country and I am trying to figure out which one I need. It is not my phone so I am not sure if he tried to do an ota, but I think thats probably what happened. Tried to do an ota, phone ran poorly, hard rebooted, and finally resulted in a softbrick. I think that may be why the recovery boot keeps saying installing update as well. Also your English was not bad at all.
Great, let me know if that solution solve your problem.
If it don't, it should not but it's possible, try with pit file (never had to use it so it's really in case it don't work correctly).

[Q] Galaxy s3, doesn't boot and shoes zebra stripes instead.

Hi everyone,
I'm trying to fix a friend's sgs3. He says his device ran out of battery while upgrading (over the air I think), and since then the device only shows black and white stripes on the screen when "on" (doesn't even show the boot samsung effect, let alone getting into the OS) . I have the device, and have tried to get it into download mode using the regular procedure, and failed everytime except once, when i really got in, but then ODIN said that I needed a PIT file, and by the time I found one the device was already stuck and I couldn't get it into download mode again ever since.
When in zebra mode, ODIN does communicate with the device, but fails everytime I try to do something (flashing a PDA file with PIT, without it, or even when I try the NAND erase, about which I read stuff on the web and it seemed like my case required it).
I'm doing all this just because my friend wants to avoid getting the phone to the phone lab (costy).
BTW he has no warranty.
The device is a Samsung Galaxy S3 I9300 32GB.
My gratitudes for any response.
Edit: The problem with odin is that he always says "There's no pit parition", which is driving me crazy, because I tried every PIT I could find on the web and it just didn't work - odin keeps on being stuck on "Setup connection". (I can now get into download mode easily)
Im using 3.10, the latest odin I could find.
Try reading the dead boot restore thread in general forum, it sounds like your emmc is fried.
I can't find it, can I have a link?

Samsung galaxy S3 Lined black-screen can enter download mode fine

Okay so i have a Samsung galaxy s3 GT-19300 Anyhow the phone was working fine perfect condition! Not a single problem But i fell asleep during a reformat for a friend and the phone got stuck on the boot-logo, I was originally able to put CW recovery but once in nothing i did would work, reformats would fail, cache wipes would fail The phone it's self had all the files on it still but non of which could be accessed by any format attempts It was also saying something about not being able to access an SD-card which i ended up trying with or without no luck, Anyhow after trying to tincker with it with odin to try and get some sort of life out of the phone something to write over the corrupted files. Nothing now the phone can boot into download mode, Without any screen-errors at all so i know my screen is perfectly fine. But if i try and boot it normally or with odin something really messed up happens i.imgur.com/lPaRreV.jpg Regardless to that happening the phone now when trying to do anything with odin will say No pit file But if you try and put a pit or do anything with any option on odin the program will say connecting to phone and not continue past that, and also when you try with Kies it will take a long time trying to connection the the phone then will say the phone timed out restart the phone to fix Nothing i do seems to fix this damn phone is it dead? Like i said earlier i can enter download-mode perfectly fine, no screen issues but still same results with odin and kies nothing works, can't put recovery mods on can't do anything
If odin can see it in download mode just flash a stock rom.
If its a btu here is the stuff you need: https://drive.google.com/folder/d/0B4vTiHTBB629ZW5vQndpbjFnblk/edit
If it wont flash the stock rom then its buggered.
I wish I stole my HTC M9.

Rooting/Rom Unsuccessful (Bootloop solved SM-G925F)

Hi. I have spent the past 10 hours trying to root my phone and install an XtraLite type of ROM because I am so sick of have 75% of my RAM used up when I haven't even started using the phone. I softbricked my phone, and after hours of trying to solve every minor issue that came up I finally found a solution and managed to flash a stock ROM. I have a lot of questions that I would love to get answers to because I am a little bit confused right now.
My history.
Bootloader
I spent so much time googling this and I decided to trust one site that said, if you can't find the "OEM Unlocked" option in "Developer Options" then your bootloader is probably already unlocked. This was the closest I got to an answer, along with many people with SM-G925F saying the root was successful for them without doing something to their bootloader. Can someone please clarify what I need to do with the bootloader with my EU SM-G925F?
Flashmode/Download Mode
Prior to this I spent very long trying the "adb-windows reboot bootloader/flashboot-windows oem unlock" without any results. However I somehow came to the conclusion that "Download" mode for my Samsung was no different. Any clarification on this subject please?
Rooting
The first rooting guide I trusted was the CF-Auto-Root page. This is where the bootloader question was raised but as I came to the conclusion that the bootloader already was unlocked, I decided to give it a shot. I downloaded SM-G925F file, added it to AP on Odin, and flashed my phone. Now my phone was locked in a bootloop. According to CF-Root page "A modified recovery and cache partition will be flashed, which will install (only) SuperSU, then clean-up the cache partition and re-flash the stock recovery. For the root to work, the device must reboot into recovery. Most devices will do this automatically after flashing these files, but in case that does not happen, please boot into recovery manually.". As you probably guessed, my phone never booted into recovery mode, and I was never able to manually do it either since the phone was in a unstoppable bootloop. Did I do something wrong here or misunderstand anything?
ROM Instructions
My first choice was: http://forum.xda-developers.com/gal...xtrestolite-deodexed-mod-edition-1-3-t3119968
I failed the first step, never even managed to root with CF-Root. And regarding TWRP, I did download the correct version "twrp-3.0.0-0-zerolteeu" I assume. However, many descriptions say my phone needs to be rooted before I can install TWRP so I never tried to install it. Even if, I couldn't find a detailed enough description of how to install TWRP. All it says is "flash it". Problem is, I am not sure if I am supposed to be in "Download mode" and use Odin loading TWRP into "AP" or how does this work?
Never got to the ROM installing, but it would be nice to have something more detailed than "Put it on your phone, install it". Like, do I enter recovery mode and navigate to the rar file and chose to install it? Not sure how this works.
My solution to bootloop
This part took me the longest. For those stuck in a bootloop. Holding DownVolume + Power button for at least 15 sec will simulate disconnection of the battery. This helps you turn you device off. Also, if you nothing happens, make sure you unplug the USB cable as it keeps trying charge and show the status it tries to boot and keeps looping as a result. I could always manage to get into "download mode" through DownVolume + Home Button + Power Button no matter what, and I am grateful for that. I managed to find the exact build I was using on my phone "G925FXXU3COJ1_G925FOJV3COJ1_G925FXXU3COI9_HOME". But everytime I tried to flash, it always failed in the end. I spent hours on google. Someone mentioned something about it failing on a certain point of the writing, involving hidden.img. I googled for info on how to resolve this, and someone suggested to rename hidden.img to hidden.tar but it did not help. I also read some threads regarding using a matching PIT file and there were about 7 different ones to chose from. I tried them all without success. Finally I read something about removing hidden.img from the ROM. I renamed the ROM from .tar.md5 to .tar. Unpacked it, and then repacked it without hidden.img using tar-Tool from these forums. The following flash of the new created tar.md5 (without hidden.img in it) was successful.
Slave for stubborness
Unfortunately since I spent so long getting through this horrible experience, I would feel bad have wasted an entire day just to get a phone that is now reset. I could have done that in 30 seconds. However I am persistent to get this working and I am truly grateful for any help you people can supply my with. I did manage to root and ROM my old S3 but that was a while ago and I only remember a few small things about Odin and so forth. However things seem much more complicated now than before.
Thank you in advance,
Alex
