Samsung Galaxy S4 bootloop - Upgrading, Modifying and Unlocking

Hi, I have a Galaxy S4 I9500 and I'm using GEAR CM13
The ROM was working fine until a while ago, but now suddenly there's a bootloop. Last thing I remember doing was accidentally holding the power button a bit long (while trying to lock the phone) so the power off/reboot menu came up and and then I tried to exit from it, but the menu didn't go away and the phone entered into a boot loop
Now, the Samsung i9500 logo just keeps flashing every 5 seconds. I'm unable to enter into recovery mode. I can enter download mode but it just exits out of that after 5 seconds and starts flashing i9500 logo again. I read about a hack to remove battery as soon as I enter download mode and it worked. It stays on download mode now. ODIN recognizes the device. What can I do using ODIN to fix the bootloop? Is there any ODIN flashable zip? I'm on the latest [20160711] build. I have important data in my device. Please help me recover it
I know I can reflash stock ROM and from there, reflash GearCM13 but I do not want to lose data as much as possible. I'm trying for fixes which do not wipe my data partition. I will go ahead with the standard method if I do not find a fix to recover from bootloop without losing data.

[Q] Keep rebooting...soft bricked? Help please...

Hi all,
I'm new to android. I did root my note 2 using the instruction by dr.ketan. I used method#1, flashing with changelu's cwm6-root-note2.tar, everything was successful. However, I can not boot into cwm recovery. I tried press and hold vol up+home+power when the text samsung galaxy note ii appeared let go the power, but nothing happen. My device would reboot again. I tried to use rom manager to reboot to the recovery, the device would show the samsung galaxy note ii and keep rebooting. Any tips on accessing the cwm recovery?
As I could access the download mode just fine, I will tried to reinstall the stock rom again and hope that it will be normal again.
I used stock rom, namely the N7100XXALIE_N7100OLBALI9_THL, and changelu's cwm6-root-note2.tar
One more thing about OTA, from what I understand, if I rooted with stock rom then using TriangleAway to reset the counter.
I will still have System Status: Custom which I read that it could be set to Official by using cwm then clear cache and wipe the device.
With binary counter: no, everything else is official, will I be able to update using OTA?
Thank you,
beau
Have you reset counter?
to boot into recovery it's necessary to press the power button only till the "galaxy note2" screen comes up, then you have to hold the vol button and the center button until the recovery shows up. maybe you'll have to try it one or two times to get the proper timing, after you've done it a few times you're into it!
regarding the reboot issue:
i had this on several devices sometimes, i fixed it always by reflashing kernel and recovery. so don't panic, its no brick for sure! had this today when i swapped my note2 for another one (due to display flaws, same old story as with sgs2 and note1). after rooting the new one i could not shut down the phone, after restoring the nandroid all was fine again!
hope that helped!
Update on my status:
I just finished reflash the stock rom. Everthing seems normal now. I just saw in dr.ketan thread that someone else also had the same issue, can't boot into recovery after using triangleway to reset the counter.
Thanks dr.ketan & TML1504 :good:
But i can't fix my problem.my phone always logo hang on startup.i try to recovery mode but phone not getting to recovery.
I think its another soft brick.i try kerner,cwm recovery & 5 different version of firmware but ODIN just says fail & there is no pit partition.
4 times Pm to dr.ketan but he also Silent.
What to do now?

[Q] Help - There is something wrong with my Phone!

Hi XDA Forums,
I have a problem with my Note 2 for some reason.
Let me explain you what is wrong with my Note 2
I was sitting down and watching a movie, my phone was right next to me, The phone randomly turned off and after couple of second it had turned back on. It had showed the first every screen when you turn it on "Samsung Galaxy Note 2 N7100". Now from there it keeps on looping the same screen over and over again.
I had done some research before opening this thread, I saw that some people said I should try factory resetting it from the recovery mode, I then tried going on the recovery mode, it was not successful, it had showed me the same "Samsung Galaxy Note 2 N7100" screen and then repeated to boot loop it self again, I tried going on the recovery a couple of times but it didn't let me go on it.
Next I had then downloaded the 4.1.2 Official Firmware from SamMobile to flash it to stock again, I had then tried going on the Download Mode, It goes to the screen for Download Mode, but when I try pressing up to continue from the warning message it had then rebooted it itself and made it self stuck on the screen again.
Basically, my phone is stuck on boot loop, It does not let me access the recovery mode and it also does not let me access download mode.
ROM Using: Tigra_RomV3 4.3 Based ROM
Kernel Used: The Kernel which comes with the ROM or Stock, I didn't change the kernel myself.
If there is a internal problem does that mean I wont get help from the Warranty because the phone was rooted?
hello,
just try to use the jig, it should work...
use it so your phone will be in download mode, then flash your rom
Do you NANDROID backup? Maybe you may restore it by custom recovery.
Second, remove the battery first for a while and retry to access the RECOVERY and DOWNLOAD mode. If not, try the suggestion up there.

[Q] AT&T GS3 stuck in boot loop can not boot into recovery.

I was running AOKP and wanted to factory reset my phone so i booted in recovery mode and it tells me i reset my phone when i boot it is just as i left it before. When i try and update the ROM in recovery I can't mount my SD card so i cant update. Finally i download an app called "[root] Mobile ODIN Pro". I downloaded the stock firmware and tried installing it. Now my phone constantly boots goes to the Mobile ODIN recovery the screen flashes with text and it turns off and repeats the process. Now when i take out the battery put it back in and hold the volume down, home, and power button nothing happens i just boot into Mobile ODIN recovery again. Same goes with volume up. If i can't boot into upload mode i don't think i can use ODIN on my PC to restore my phone. Did i **** up my phone is there ANY way to fix this?

[Q] samsung galaxy w keep rebooting

Hi,guys,
my galaxy wonder keeps rebooting i cant even go to recovery mode & downloading mode when am trying to go for downloading or recovery mode it just keep rebooting again & again without showing anything. :crying:
please help me what should i do now ??????
thanks
Are you using custom rom?
Give a try. Just flash stock rom.
Go to download mode, and keep tapping on power button when you're in download mode. Tapping power button is to prevent your phone to reboot. Then flash stock rom via odin
One day, my sister got this problem too. So I concluded that the problem was in the custom rom. So, I flashed my sister's phone back to stock rom and everything went normal.

Galaxy Ace 2 GT-I8160 bricked

Hey. Thought I should flash cyanogenmod 11 into my mom's phone. When I did it, realized that Ace couldn't connect to carrier for some reason. Anyways I decided to get back to stock GB. I've already tried to flash maybe four stock builds of GB and JB (they were all from "SamMobile") through Odin, but none of them really boot up, I get stuck at Samsung logo.
Recovery won't work, even if I flash a new one through odin ( f.e. this one: http://forum.xda-developers.com/showthread.php?t=2532591 )
Download mode does work.
I saw there was this 3-part GB installation file from a russian guy, which I should have used, but it's already deleted in "Yandex". I live in Lithuania, so I'm supposed to use SEB version of firmware. I was wondering could someone reupload it ?
I tried to fix Ace through Kies, but it says that GT-I8160 recovery isn't available for some reason...
Any answers greatly appreciated.
Thanks!
After flashing the sammobile rom with odin, if it doesn't boot, go to recovery (the original one coming with the original rom), and do a factory reset/wipe data. This helped for me.
The problem is that even if I try to enter recovery (power + vol up + home), it stays stuck at samsung logo
You can try to insist by continuing pressing the 3 buttons for recovery even if the phone reboot. If you're stuck in a boot loop, you can also try to remove the battery to switch it off and switch it on again by pressing the 3 buttons.
For me the odin flash of JB rom + recovery clean up always solved the problem. I don't know any other way.

Do the official ROMs (tar.md5) come with official recovery, or do I have to flash one seperately ?
The official ROM include an official recovery, you don't need to flash another one.
i too needed to go back to the stock from from cm11, because i cannot get wi-fi direct to work.
i flashed an xxmf1 rom, but when the phone rebooted, a message said samsung set up wizard has stopped, and i cannot get past it. this is even after doing a factory reset.
i went back to cm 11, and flashed the stock rom again. this time, the rom flashes in odin, but takes long to go from reset to pass, and windows now says hardware id is missing.
the phone goes black after the samsung logo, and cwm is still installed.
any help would be appreciated.
edit: fixed by flashing the three-part gb rom - http://forum.xda-developers.com/showthread.php?t=2141930
Turns out I disconnected my Ace 2 too early (dammit). As soon as I saw "RESET" in odin, I thought it has finished flashing and I disconnected it before it goes into recovery and flashes everything. Never thought I could be that stupid.
Thanks for replies tho :good::good::good:
