Galaxy S3 neo does not boot after successful rom flashing - General Questions and Answers

I have a Samsung Galaxy S3 Neo (GT19300I) device and I flashed a KitKat rom into it. After flashing, the Odin gave the PASS message, but my phone did not boot up. I tried boot it up manually, but it did not work. I cannot even get into download mode or recovery mode.
One thing to mention here is, I tried rooting my device before doing the above process, In that case, it did not PASS. Then I tried to find a solution and one solution said to flash a rom to the device and try. That is why I flashed a custom rom into it.
What has happend to my phone? Is it dead? What can I do for this?
Thank You..!::crying:
EDIT: when I connect my device into Windows machine, the device manager makes a sound to indicate that a device is plugged in. But I cannot see any device plugged in and even Odin does not identify a phone connected

[Q] phone bricked and not getting detected on computer

Hi,
my friend's Nexus S was stuck in a bootloop. i went into recovery mode and hard reset the phone, so that the phone would come back to stock. however, the phone was being reset when the battery of the phone came off, switching it off.
the phone fails to start. there is no response when i try charging it. Also, it does not go into DOWNLOAD mode or FASTBOOT, so i cant even run any utilities to flash the stock rom back. adb commands as well as the nexus toolkit show that there is no device connected.
can anybody suggest me what to do?? i was gonna try odin but i read somewhere that it is only useful for custom recoveries, not to flash stock roms.
i've gotten some usb drivers mentioned at some thread, saying i would have to update my 'android' device listed in the device manager using them, but i cant seem to find any device mentioned in my device manager either.
any suggestions as to what i should do??

Something like this happened to me a week ago. I have Nexus S 4G. So, I ordered USB Jig from usbjig.com and now I have download mode. It worked! :laugh:
You can buy USB Jig from that site, or build it yourself, or borrow it from someone.

[help] phone stuck in bootloop

Okay so some of you might know that there is a ram management fix for the Samsung S6 by editing the build.prop file. I tried doing it and my phone went into a boot loop(it just repeatedly show the white text of SAMSUNG GALAXY S6). My phone is rooted by the ping pong method which doesn't trip knox. The last 2 things I want to do is go to a samsung store or flash a stock rom which wipes my data.
I saw a video that you can fix it by using adb. However, when i plug my phone in my pc while my phone was in recovery mode, the pc doesn't detect. But if my phone is in Download or just its boot loop mode, the pc detects but it often says "Your last device is not recognised or malfunctioned" or something like that. Yes I do have drivers installed including Kies3.
All I want to do is just to fix my s6 build.prop file without
1. Tripping the knox,
2.Not visiting the samsung store
3.Factory resetting my phone and flashing a new rom.
Please help. Thanks
*********EDIT***********
I found out that you can flash a zip file that restores the build prop file here:

It's one of the replies to the post.
But I'm an odin noob so... how do you flash it???
***********EDIT AGAIN*********************
Okay... soooo I'm stuck now. I can't even get my s6 to connect to my pc. It just says usb device not recognised.
I already tried:
-Redownloading samsung usb drivers.
-Installing Kies3
-Installing Smart Switch then clicking more and reinstalling usb drivers.
-Using different port.
-Using different wire.
-Blowing into port and phone port to clear debris.
Help :/

Need help with unbricking Samsung Galaxy S6 [G920F] - stuck on boot loop

I'm completely hopeless, and all I can count on are good people from XDA to help me.
I bought a new Samsung Galaxy S6, T-Mobile version [G920F], running Android 5.1.
I used this tutorial:
http://www.droidviews.com/root-samsung-galaxy-s6-and-install-twrp-recovery-all-models/
I enabled USB Debugging, downloaded latest Samsung USB drivers.
First I successfully installed TWRP 2.8.7.1, and meanwhile copied the SuperSU.zip to my device.
I had successfully entered TWRP, went to Install, and selected teh SuperSU file. It said it was done, so I went ahead and restarted my device.
Immediately, I noticed that the device was stuck on the boot logo (Galaxy S6 + Powered by Android screen).
And for some reason, when I connect the device with USB to mc PC, Windows says it's "damaged or undetected", something of that sort.
Luckily, I can still detect it in ODIN.
I might mention that I can still enter TWRP & Download Mode from the Bootloop.
I'll give any more information I can, just tell me if there is any hope for me.
Thank you so much.

[Completed] Need help with Samsung Galaxy S4, Model: (SM-S975L)

I'm not sure if my phone is soft bricked or hard bricked. My phone was having some kind of firmware issues so like an idiot and not backing anything up, I tried to flash a stock firmware on my phone with odin and it failed. My phone is not rooted or anything it is complete stock and now when I try to boot up the phone I'm not sure if it goes into recovery automatically or what but when I turn it on it goes to this screen saying "Firmware upgrade encountered an issue. Please select recovery mode in Kies & try again.". If this is not recovery mode then I can only go in download mode I have tried going into recovery mode. I've tried odin several times, using different usb cables and different usb ports on my computer and still nothing, I have used Samsung Kies and Kies 3 they both fail and then tell me that I need to do emergency recovery from another computer with a code but it is just blank when it comes up it does not give me any codes. I've even went to Tools > Emergency firmware recovery and still shows no codes or anything it is still blank.
Suggestions?
I fixed it, for anyone who may have the similar problem this will help you: https://forum.xda-developers.com/galaxy-s4/general/guide-sm-s975l-twrp-4-4-2-custom-roms-t3009757
For me, all I needed to do was flash twrp recovery and my phone started working again so I decided not to mess with anything else

SM-G920F stuck in bootloop with stock recovery, computer cannot recognize device

Hi everyone, I ran into a serious problem today with my S6 G920F. I was running stock android 7 with Magisk and TWRP installed, I flashed the firmware using Flashfire from the Google Play store.
This morning the phone decided it would stop charging, a problem I faced with Android M. Anyway I reflashed the firmware package but this time i chose NOT to select the options to inject supersu and save my custom recovery, thinking that I could get it back to stock and re root it from there.
The phone previously would not boot if either Magisk or SuperSu was not installed (after i rooted it), it would just endlessly loop. Unfortunately this was the case after i flashed the firmware .
I assumed it would be a quick fix as I could just use Odin to flash the stock firmware . Unfortunately I was wrong again: my computer gives me an error message "USB Device Not Recognized" no matter how many times I uninstall and reinstall the Samsung Driver, Odin wont detect the phone either. Even Smart Switch is at a loss. The phone is currently plugged into my PC and is charging normally, I CAN boot into stock recovery and download modes.
SOMEBODY PLEASE HELP!! :crying::crying::crying:
Seems very obvious now but I found the solution I found the original cable that came with the phone; plugged it into the PC and just like that the computer registered that it was a Samsung devices and started installing drivers right away, seems like the P8 Lite cable I was using isnt a data cable?
I was able to flash TWRP using Odin and flashed Magisk using TWRP. All is well
