Okay, so I'm not completely new to all of this. I own other android devices and have rooted and flashed them..
However, I recently got the AT&T S4 (SGH-I337), and due to my own fault, I mistakenly clicked on and flashed the wrong kernel to my phone. It will not boot. It just sits with a black screen while it vibrates every 3 seconds, non stop. I cannot enter recovery, nor does any logo appear.
I have only been able to enter the Odin Mode and already attempted to use the stock rom located here:
http://forum.xda-developers.com/showthread.php?t=2261573
I have also tried downloading the files from the Sammobile.com website.
Odin goes through the process of flashing the stock rom and successfully finishes the process each time. It still does not boot and only vibrates.
I have also tried Kies; however it says that my SGH-I337 doesn't support initializing.
I truly am at a loss, here. I have been up literally all night searching the forums and various websites. Odin seemed to work for most, and for those that it didn't, they were able to enter recovery to do a reset.
So in short..
Phone only vibrates and doesn't boot or show logo.
I have already flashed the stock rom using odin.
I cannot enter recovery.
I have tried pulling the battery and entering recovery.
Is there anything that can be done at this point, besides taking it to AT&T?
Which kernel did you flash?

I mistakenly downloaded the Ktoonsez kernel for the S3 for Touchwiz JELLYBEAN 4.1.2.
It failed, but hasn't worked since. I did, however, flash the stock kernel with odin, but that still has done nothing, even though it said it was successful.
So does anyone have any idea what can be done? I'm open to suggestions!

Yep Sure Do...
1st If your able to boot to Odin and you see the download screen your not bricked...
Also the window for entering recovery is very short with the keys so continue to try...
1. Do you have a stock or custom recovery?
2. Do you have any back-ups on your SD card?
let me just say I ran into a problem few days back with a similar problem...
Please answer questions and we will get to next step.... DON'T PANIC!!!:good:

I've used odin at least 5 times. Getting into download mode isn't the problem. All i have to do is hold the Volume Down button while it's doing its infinite vibrate ever 3 seconds.

The key is getting into recovery...
Make sure you are using the right key format...
1. Hold Power Volume UP and Center key at the same time
2. when you see the Blue recovery words... split second release power and center key hold volume up for another split second
3. release volume up then hold down again
If you do not go into recovery you missed the window... try again

Okay, well that's the problem. It's only a black screen. No logo or blue letters pop up. I have been into recovery mode several times, so I know what I need to do.. It's just not possible with how the device is currently behaving. As soon as I put the battery in, the phone vibrates after 3 seconds, then repeats every 3 seconds. There is no logo, or lettering. The screen never turns on. The only times the screen turns on is when i enter Download Mode.
once your in recovery...
TWRP breaks up parts of the back-up
Remember in this step you are not trying to restore....
try to install each section of the back-up this will clear your frigged up partition
I do not know which is corrupt so its trial and error...
It will state that the flash was unsuccessful but it does flash enough to clear your corrupt area!!!

Have tried ODIN flashing CWM or TWRP and not the stock rom?
Related
I was trying to install Wanamlite through TWRP, but I did a couple things wrong. I have flashed custom ROMS before, but I think I was just careless this time.
The things I did wrong are:
I installed the wrong kernel, I used this one KT747-TW-JB-4.1.2-ATT-05-31-2013.zip for the GS3.
I did not click "reboot" after install of the ROM and kernel, I held down the power button. Don't know what I was thinking!
I then tried the factory ROM through ODIN as discussed in this thread http://forum.xda-developers.com/showthread.php?t=2261573, everything in ODIN told me things were going smooth. Now when my phone tries to boot up it just vibrates every few seconds repeatedly with nothing displaying on the screen.
I thought my phone was supposed to boot right up after installation!! Any ideas?
It will be better to keep the discussion to this thread instead of the ODIN thread. However, here is a thread...
http://forum.xda-developers.com/showthread.php?t=2327226
...with a very similar issue to yours. If you definitely can't get into recovery (keep trying different key combinations and timing) and Odin doesn't work, you appear to be screwed at the moment. Maybe you can try some ADB options. You will need to search for information about it and there is no guarantee it will help you.
Unless something else surfaces, Jtag repair might be the only option. You can search for information about that as well. Good luck.

Thank you, I treid the button combinations but sadly I don't think that's the problem. I'll try some ADB options and look closely at some other threads. Looks like I'll have to reactivate my iPhone 5 until I get this problem sorted out! What a bummer!
so you're able to get into download mode but not recovery, correct?
xBeerdroiDx said:

Click to expand...
Click to collapse
Yes that's completely correct!
since you've already flashed back to stock via odin, i want you to try booting into recovery again. just to start from the beginning and cover all the bases.
pull the battery and wait a few seconds
reinsert the battery and immediately press the recovery combo: vol up + home + power (in that order). release just the power button as soon as your device vibrates while still holding down vol up and home.
if this does not get you into recovery initially, try the method a few more times and report back.
if this does get you into recovery, wipe data/factory reset, wipe cache and reboot.
Thank you for the thorough instructions. However, it did not work. I tried 12 times with no success.
Phone just kept vibrating every few seconds and would not go into recovery.
until we find out a little bit more about this issue, i personally dont have much advise to offer. are you familiar with adb?
scott14719 linked a thread pertaining to your issue. i'm sure you read it and see that you're the only one in this situation.
i will continue to do some research.
Isn't there a Kies emergency recovery or something. Just putting it out there.

Yep, but kies has to recognize the phone, which is hit and miss. If kies recognizes the phone, it would be worth a try.
Try to flash your carrier rom again using odin. Download links can be found here http://www.sammobile.com/firmwares/ once you get the PASS in odin your phone may still be stuck in a bootloop. As xBeerdroiDx mentioned , try removing the battery then go into recovery and restore to factory settings. I had the same problem with twrp ,I was stuck in a bootloop , no restore , no boot nothing. My phone is working now thank god.
Try this and report back

I was unsatisfied with Safestrap( Only a few roms would work for me and the wifi never worked), so I uninstalled it using the built in uninstaller in the app. I installed ROM manager and installed CWM from it. I rebooted my phone and CWM and system reboot to the " Unauthorized software installed" screen, only download mode works. I attempted to install the stock firmware from Odin but it would say fail (auth). Nothing I do on Odin is working. What do I do?
After installing either the AMDL or AMDB it either says "Can't open the serial(COM) port." or "fail(auth)", always on the first step.
By AMDB or AMDL I mean the md5 files

Have you read anything that is posted in the forum? Considering everything in your above post has been covered many times (and you didn't follow the information already posted), I would say you have not. So the answer to your question, "What do I do?", is to take the time and read about what you should have done and what is now available for you to try. Start by reading the "pinned" threads in the General and Q&A section and then read any thread with "MF3" or "safestrap" in the title. You can also use the search function of the forum to find more information. Good luck.

I'll tell you this if you didn't manually uninstall SS you still have it.
Pull the battery and before putting the battery in hold the power and volume down ,let go of the power button and hold volume down it will go back to the unauthorized ATT screen again.now push volume down it should go to boot up and you should see the SS splash screen. Hit our menu button at that splash screen and it should go to SS recovery. I have done this plentty of times

Can you make those instructions just a little bit more clear?
Like for example when do i put the battery back in?
U put the battery back in wile holding the power and volume down.give it a couple of seconds and let go of the power but still hold the volume down till the unauthorized ATT screen comes up.press the down option and it will boot in my case the custom with unlock icon followed by the SS splash screen. You should know by now what to do when you see the SS splash screen

I'm trying to respond to you lol
Give me a couple minutes.
Did you get the message? if not i'll just put it here.
So the problem here is that my phone won't enter recovery mode. I think it's because it's deleted. I installed safestrap and did a factory wipe but it gave me errors(something about datamedia/media) so i just deiced it's best to deal with it in the morning, so i rebooted. The phone stayed on my boot logo(Samsung Custom) and then things started to get worse. I hold the 3 buttons to boot into recovery, only problem is that the blue "entering recovery mode" text shows up for a split second and then gives me the android figure you would see if you were in download mode for another split second and then reboots.
I know that MF3 is having some flash problems so i can't flash the stock rom because i already tried with 2 different stocks rom. I also already tried to use the custom pit files that were used to fix the bootlop issue with kies or whatever (adonis.pit, MF3_BTL_FIX and SGS_I337_16GB), which came out with no luck.
If you can help me out with that then i'd be more than happy to make a skype call.

Are you sure you cannot get into download mode? Hole power til you see the LG logo twice, then release so it powes off completely... Then hold only Volume up and plug the phone into your computer while holding it.

I am not sure if you this will help 100% but what I did was installed the recovery in my phone then I updated my phone. Which made my phone go in recovery and if I restarted it gets stuck in recovery. I wasn't able to get in download mode as well.
If you can get in "recovery" then you can use this fix
to get in recovery hold the vol- and power button until your phone vibrate and you are in recovery.
then execute these commands through adb shell
http://forum.xda-developers.com/showthread.php?t=2451696
Edit--- after executing the commands flash the stock rom--- using LG flashing kit. Search the xda and you will be able to find a thread that details how to do it. yes you will be able to get in download mode, i got there in 2 tries.

Sorry, can't read the link, but by recovery, you mean TWRP, right?
So basically, after rooting we can still do an OTA update, and it's still safe, right? But once we installed TWRP, we should not do any kind of OTA updates?
For TWRP, is this method good enough:

To Root, I will use this method:

Sorry if I am steering topic off-course but I just wanted to make sure others don't do the same mistakes and end up in same situation.
Your suggestion of not doing OTA update is really valuable, so I wanted to build on that.

but you should check which phone you have and which OTA version you have. As far as I know 11g and 11c for korean variant can only have cwm i am not sure if that is true for other phones as well. But be sure to check it. TWRP only works for 10x versions (where x is any alphabets) still dig deeper, I might be wrong.
But you should never update your phone after recovery.
and backup your IMEI number ... the thread i posted earlier try using google translate and download the apk to backup your IMEI by Hoang.

you will get vroot
Hey guys I just got another one of these damn G2s
Anyway, got root fine on 12b and had issues trying to push the twrp recovery image to it, it kept failing for some reason. So I tried the Flashify option... and as you can tell by the thread title it worked excellently. And by excellently I mean I'm bricked.
I can get into download mode. But it won't boot past the LG logo. All I get is a black screen. Can someone help me revert to stock and get twrp installed?
Thanks:laugh: I'm using an S4 right now so no rush.
Also I'm a little illiterate on Android so take is slow and dumb it down- I don't develop and I don't code, I just enjoy other people's work as a casual user.

Try holding volume down + power
Immediately when LG appears let go of both and ONLY hold onto power, should boot into option to factory reset
Hit power button 3 times to continue.
Tried that. It processes the reset and then immediately tries to reboot, and bootloops again.

WHen your g2 is powered off just hold volumeup and connect to a PC. If it doesn't go past the blue dots then you can't enter download mode either.

The white screen where you can hard reset the phone? Yes.. I can get into it, but accepting the reset simply puts the phone back into a boot cycle.

Just remove the battery, put it back again and go into recovery mode (twrp). And do a clean flash again. If it doesnt work, then just flash another rom. Put the rom inside the sd card and flash it via twrp

When you put the battery back., do you press and hold down volume down and power button and then whe I the logo appears you rapidly release and press and hold the power button without removing the finger from the volume down?
Its all about timing to be honest. Took me about 10 tries before I noticed I was being stupid. Right before the corrupted screen shows up, there is a very small window that you have to do this at. What I do is this.
I hold the volume down button while it is fully powered off.
The I press the power button and as soon as I see the LG Logo (It pops up for a split second before the corrupt screen) I let go of the power button and then press it imminently after I let go of it and TWRP shows up in a few seconds.
Again, its all about timing.

Since you have TWRP, just hit yes to both. It wont wipe anything. I paniced as well but had backups so I clicked yes. and it booted TWRP

Did you install the H918 Rom or the US996 Rom?? If you didnt flash the TMO rom then you might be SOL. And it seems that whatever happened crashed TWRP as well... Are you able to get adb to detect the device?

To be honest, im the least qualified to try to help! It just stays at the lg logo the entire time? No static screen or anything? And TWRP crashes no matter what? If you can get it into download mode you could try to restore jt using a KDZ for your model?
https://drive.google.com/drive/mobile/folders/0B6Wj13Rw1kw-QTViRFJRaVRHQnM?usp=drive_web
You could try LGUP to see if you can restore it. Just make sure its the right model..

you could try to push TWRP into the system by using adb, just in case it has become corrupted. Then, if that is the issue then that should fix it.

Try this to go into fastboot mode : http://www.hardreset.info/devices/lg/lg-v20/fastboot-mode/
pull battery out put back in. Hold volume down, plug in USB to get into fastboot

Weta is amazing, just use the one for your phone! Or it wont function. If you have the tmobile model then only use the tmobile rom xD Just make a backup in TWRP before flashing so you dont have to start completely over.
