Locking up straight out of the box

Just got my new i9500, turned it on and with in minute it locked up then rebooted (no sim or mem card at this stage).
Did't think much of it at the time. Went ahead and rooted it & flashed Omega rom.
Unfortunately it continues to lock up & reboot every few minutes of use. Looks like it is faulty and will have to go back for warranty. My concern is the rom counter and warranty. Will flashing a stock firmware with odin put the counter back to zero?

Flashing stock with odin will not reset Samsung's rom counter. From my understanding, there are ways to reset the counter, but you have to be very careful because it has the potential to really mess up the phone. If you flash back to stock rom and stock recovery and relock the bootloader, you will be able to exchange it wherever you bought it without an issue (assuming you are still within the 14 day period most carriers give you). No one will look that deeply into the software of the phone until it gets back to Samsung. And even then, it is not guaranteed they will check that. I'm not saying it won't happen, but the odds of you having any issues are slim.

Flash a Stock Firmware using Odin below is the link u can find a firmware of ur cell
http://forum.xda-developers.com/showthread.php?t=2265477&highlight=stock+firmware
after flashing a firmware again reset the device from ur cell
and i9500 has hidden counter mostly so u cant see how many flashes u have got however there isnt any way to reset also for now may be we have to wait till chainfire gets one for i9500 .. Once u flash a stock firmware it will show official hopefully they will replace it
Make sure its saying official on download mode and also in abous us / status / device status all should be official of whatever samsung writes

I have flashed a genuine firmware but it still says "Custom" when I boot into download mode.
Any ideas how to get it back to official & reset counter?

[Q] Samsung Galaxy S4 REALLY unfixable

Sup guys. I have a problem with my S4. I doubt anyone will be able to help me find a fix but its worth a try. I hope someone will help.
Anyway, I flashed my GT-i9500 (Galaxy S4) from 4.2.2 to 4.3. Now it doesnt boot, It just gets stuck at the 2nd boot screen. Its not even a bootloop. It just hangs there. The S4 sound that plays gets cut like halfway.
I tried flashing a lot of different ROMS, and it still does the same thing. When I rooted it, I noticed the boot welcome sound plays full, but it still hangs after that.
I used Philz Recovery and mounted all the folders etc, but efs says invalid. So that means the EFS folder is messed. I get that, but I cannot repair the EFS if I cant boot the phone, I need the Samsung MTP **** for Samsung Tool to work. I have an N7100 (Note 2) Where I repaired the EFS with Samsung Tool, I was able to boot the phone.
I looked ALL over the net including this forum and found nothing. Right now the phone is just worth nothing. This is my last option, to ask here myself. If it cant be fixed I just cut my losses and get another phone.
I also flashed a PIT file, CSC file, Modem file during the period I was trying to get this fixed. If anybody knows this problem, It'll be very helpful.
Thanks.

you could try upgrading to 4.4, i have all the files for omega v21
heres the link for all the stuff from my google drive.
https://drive.google.com/folderview?id=0B_trhAurRvdmb0RkNGpoTkVNU0k&usp=sharing
instal the bootloader and phone file via odin, bl = bootloader cp = goes into the phone part of odin
then fash the rom via philz recovery, worth a try !!
good luck

That wouldn't work, thats for the Snapdragon variant I think. The i9505. I have the i9500. I'll download the Omega ROM for i9500 and try it anyway.
Thanks.

Still doesnt work.

Did you tried complete of phone, than power and vol up, at the buzz lose vol up and at loge lose power button.
and then flash with odin bl. and modem
etc.

I've flashed with Odin & Recovery.
I flashed another bootloader, XXUEMK8 & Odexed Knox Free Stock ROM XXEUMK8 & it still does the same. I dont know whats wrong with it.
Another thing I forgot to mention is if I root it using Odin, the welcome sound plays full and it hangs, and if I reboot it, the welcome sound goes back to cutting off again.
This phone probably cant be fixed. I dont know wtf's wrong with this phone. This is WORSE than hard bricked.
oh & as I mentioned before, I have a Galaxy Note 2 & had an EFS problem with it. I fixed it, the difference was this Note 2 actually booted properly with any ROM installed. I used a Z3X Box & Samsung Tool to fix up the EFS. Maybe this problem is only with i9500 or with i9500 & newer models.

Eeeer don't mean to point out the obvious here but you did do a factory reset in stock recovery after flashing stock 4.3 in Odin? That's all you needed to do at the start.
When I went from 4.2 to 4.3 I couldn't get it to boot at all unless I performed factory reset after flash.
Sent from my GT-I9505 using XDA Premium HD app

I came from a rooted Samsung org. rom 4.3 to omega v21.1 Android 4.4.2
After this i tried slimkat, and had from first start the same issue, no booting.
Nothing works
only starting with power and vol. up as descried above, I could flash XXUFNA5 bootloader & modems.
After this twrp.
And at last I flashed S4 Google Edition - 4.4.2, a ROM for the Samsung Galaxy S 4

Thanks for the help people.
I gave up on trying. I tried everything even factory reset after flashing, different ROMS, different Android versions. 4.1.2, 4.2.2 & 4.3. Today I ended up selling the phone's LCD. Atleast I didnt everything. lol. Wouldn't be buying another Samsung EVER. I was thinking I need another box and stuff, like NSPRO but I dont have that.

[Q] flashing Stock UK BTU though on boot polish language shown

Ages ago because i was impatientto update my phone so i flashed the Polish Stock using Odin, since then i have used Odin to flash the UK Stock, though when i wipe and reset the phone it still initially comes up with the polish language, (not a massive issue i know but i want to get UK OTA if it ever comes) also if i go to sell the phone at the end of this year when the Note5 is out im sure the new owner would want to turn it on and see english.
Ive tried
Clearing the EFS cache and resetting the phone from recovery before and after flashing BTU
I made sure reactivation lock was off as I wondered if that would cause an issue though that hasn't helped. does anyone have any other ideas?
Im un-routed as i sometimes use my phone to test out corporate BYOD so cant root of flash a custom rom.
thanks all for any help.

Download Phone INFO Samsung from Play and check the CSC.
But it might be you are rebooting into DL mode instead of shutting down the phone then starting it in DL mode. I usually remove the battery for a bit and hold the power button for a few secs to make sure the mainboard is completely discharged. Odin (& other methods) all have problems changing BL and Modem if you just do a reboot into DL.
You might want to take a look at Multiboot and Recovery for the possibility of having the ROM you want, rooted etc. AND still have a stock ROM you can choose to boot into for work purposes.

Note 4 Stuck in Boot Loop - Help - Recovery not working - Flash stock Rom not working

Note 4 Stuck in Boot Loop - Help
I have a Note 4 SM-N910F, never been rooted, stock rom upgraded to 5.1.1 back in October, working fine until yesterday when it got stuck in a Boot loop.
Not sure what caused it but before it got stuck I was messing around with Google Photos which was running a bit slow.
Also I put it on the Qi Charger just before the loop started. It has an aftermarket Fone charger stuck to the battery. I’ve had this and the Qi Charger for 6mths with no problems before now.
It gets to the Samsung page waits a couple of seconds then boots again.
Here’s what I’ve tried - unsuccessfully - to fix the boot loop:
1: recovery mode.
I can get the little recovery text to appear in the top left but after a few seconds it boots again.
2: volume down, home
This gets me to the screen with up/down for continue/cancel.
This is the _only_ screen I can get to stay up without rebooting. It sits there waiting for input.
- Cancel, causes restart, of course, but back into the bootloop
3: Mashing on power button. Banging it, wiggling it, blowing on it.
I read somewhere this could cause a boot loop, but I doubt it is my case because
a. I’ve never had problems with the power button before
b: When I take out the battery and put it back in, it does NOT turn on. If I do the same holding the power button, it powers into the boot loop. So if the button were jammed on I would expect it to never remain off with the battery in.
3: flashing stock rom
I’m not 100% sure what build I had before. I know it was stock 5.1.1 OTA, and I’m pretty sure it was unlocked (my wife bought the phone and i inserted my old sim, but she may have bought it from my carrier and can’t remember)
So anyway I tried all three versions of TPH (unlocked) 5.1.1 from Sammobile.
Installed Odin 3.10.7 and flashed them.
It reboots to recovery but immediately boot loops again.
I doubt its to do with the version of the rom anyway since the symptoms are identical after flashing. Only now the boot loop always shows the little ‘recovery booting...’ text in the top left.
Here’s what I have NOT tried but am thinking about:
A: Re-partition option in Odin
B: Nand Erase All option in Odin
C: Buying a new battery.
On A/B: as far as I can tell what I have done so far should have left the data intact. I’m prepared to wipe all my data if it fixes my phone (no lectures about backups please!) and I’m tempted to do one of these on the off chance that the problem is caused by data or the “disk" problems.
But I don’t want to brick it. Can someone recommend how likely these are to help
And what they actually do?
(Please refrain from responses I see elsewhere like “this will brick your phone if you don’t know what you’re doing”. I don’t know what I’m doing, thats why I’m asking - just the facts please)
On C: the battery seems ok in that the power is solid even after not being plugged in for a long time, but since it was on the Qi Charger with that aftermarket thing stuck to it when it happened, I’m suspicious. Can any one say if this is a likely cause?
If so, it might be worth waiting till I get a new batter before doing A or B (can I wait days for Amazon!?)
[UPDATE] Got a new (genuine) battery at a local electronics store. No dice. Same problem, so it's not the battery. Shall I go ahead and re-partition.
[UPDATE] Got a PIT file from another forum, and flashed again with re-partition checked and PIT loaded. same results.
Is Nand-rease worth trying?
The phone is still under warranty so maybe I can return it.
But in that case I want to erase what's on it first.
thanks for any help

I don't think that the Samsung service center will accept cuz u have unofficiall custom
Simple Go to ur any nearby SOFTWARE ENGINEER may be he will help u out
Even I had the same problem with my NOTE 4 EDGE

Try downloading and flashing any "COJ5" build of 5.1.1 from sammobile. Samsung has recently issued a new update "COJ5" it basically locks down the bootloader and will not allow the device to run any previous builds.....Maybe your phone updated to COJ5 in the background and then it started messing around because the phone is rooted. Flashing "COJ5" will lock your bootloader and you will not be able to flash 4.4.4 or 5.0.2 but there is nothing to lose when your phone is already pretty much dead?.....ORRR if this is not a software issue then it could be related to hardware maybe the memory of your phone is done. I am not an expert on this but this is just an advice.....i have told you what will happen if u flash coj5 build now its up to you to decide. I would suggest you wait and wait if you are lucky to get a response from an expert and do what they say .......if not then give this a try!
**EDIT** another idea....First flash a custom recovery such as TWRP....see if it lets you boot into recovery and if it does then perform all sorts of formats.....and factory resets in there see if it works....if its still rebooting after format then flash the coj5 build of 5.1.1....note that you "MUST" format it with TWRP first and then check if its working because once you have coj5...it might not let you flash custom recoveries.

You can flash TWRP through ODIN while on COJ5 bootloader. It's locked but you still can flash recoveries and kernel and 5.1.1 ROMS

I am very interested in this thread. I have the EXACT same problem as you have after installing SimplRom, which was a ROM prior to COJ5. It could indeed be that our bootloaders are locked now?
I am using the N910F and just like you, installing any ROM/Custom Recovery/Bootloader/Kernel doesn't help. Perhaps installing a COJ5 ROM might help. I will give that a try, but I've recently used Kies to install the latest official firmware, but it didn't fix the issue.
I will report back here and we'll work on this together to make our phones work again!

Thanks to you and dork97 for the ideas. First some notes:
- I have never flashed a custom ROM, nor ROOTed this Note 4. The recent upgrade to 5.1.1 was official.
the first upgrade to 5.0.1 was automatic and after that I turned off automatic upgrades and upgraded to 5.1.1. manually. So I dont think it was an upgrade that caused it and it certainly was NOT a custom ROM or ROOT. I was doing nothing at all when the boot loop started.
- I'm not sure what ROM I had, but when I went looking for the available Portugal unlocked ROM, which _should_ be what I had, the latest were CJ03 (3, not 5) and before that CH03, CI03. Presumably I had one of those (my last update was October, so probably CH03).
I have tried all 3 of these, but the symptoms are the same.
I'm tempted to try the TWRP option - but would like some more details on what is and what it does, or what problem I might have that it would fix.
However I am probably still in time for a warranty repair - especially since I didnt actually do anything for this to happen. I would like to avoid losing that chance.
If I do take it in for warranty, I'd like to wipe the memory first though. How can I do that?
Finally can anyone actually tell me if the NAND ERASE is likely to help? How does flashing TWRP compare?
I get the feeling in fact, that I have a hardware problem. Especially given there were not software system changes around the time it happened, and given that it loops while trying to boot into recovery mode. In fact the only mode that doesnt constantly cycle is download mode. (Even holding the power button in dl mode does nothing which makes me suspect that, but pulling the battery out and replacing it leaves it off until I press the power button so perhaps not)
Thanks for the replies so far. Any more ideas, details?

I have the exact same as you. I did install a custom recovery (multiple) and still get the bootloop. From my tries yesterday, I indeed also suspect it may be a hardware issue. Perhaps to do with the battery/charging port. When I have my device unplugged and try to start in recovery/normalboot, it does not have a bootloop but simply turns off (and then doesn't respond until I pull the battery out). I think a NAND erase wouldn't do anything as I've personally tried that already.
Have you prior (upto a week) before you got the issues had your phone in a moist environment (bathroom while showering for example). I got my problems a week after I accidentally left my phone in the bathroom and installed custom ROM (which was done earlier and had no issues).
I've read online that it may have caused oxidation on the inside and may need some cleaning/drying with alcohol.
I still hold hope that we just have a software issue as download mode is working fine (apart from the Power off not working unless we pull out the battery).
Anybody have any experience with oxidation on their phone? Perhaps have had a similar bootloop due to hardware failure?

Since you can get into download mode I'd flash firmware through ODIN again after verifying it's correct.
I'm seeing off the sammobile site for the 910F not all are the COJ5 locked bootloader.
Since you did update in Oct you may be on the COJ3. I'd try one of those and see if it works.
If it doesn't work and stops on the sboot.bin file then you have the COJ5

i am sorry i don't know any way to remove personal data other than doing it via recovery. There is an option of "nand erase" in odin it is used while flashing firmware and it wipes everything on the phone but i have never used it (and also don't know whether it can help you or not) ... Senior members kindly help us with this.

Any update to your situation?
very interested as I am in the same situation as you are. Download mode works, recovery+normal boot not. No matter what ROMs/recoveries I install

Same issue I think
I am also in the same situation, although I can enter the recovery mode - home power and volume up - I have tried the wipe cache and then factory wipe to no avail - I have also entered download mode and flashed the stock recovery and even though Odin says pass, it is still in a boot loop. Also when I go to the download screen it has a line saying knox warranty void 0x1(4) does this mean I have voided the warranty even though I only used Odin to flash stock recovery?

Did anyone found a solution
Did anyone ever found a solution to this problem I'm having the exact same issue on a note 4 smn910a

I have a slightly different issue with my Note 4 SM-N910G, wherein am not able to start the phone at all, it is completely dead, if i put the cell phone on charge then also there is no LED on the top but if i connect the device to the PC it does make the connected sound on the PC but Odin is still not able to recognize the device neither kies. I tried draining the power by removing the battery, connected the device to PC without battery and then inserting it but the same problem. Please suggest me any resolution for this dead body am carrying from past few weeks.

hi Op,
did you find any solution for this issue?

Hello all. This is advice to use as a very last resort if you are experiencing the recovery bootloop issue AND you don't have the emmc failure bug. I had the recovery reboot, sudden shutdown with no warning, etc. issue for the past two weeks. I tried everything on Google and Youtube to fix my problem with no success. I flashed multiple stock ROMS and recovery tars (stock and TWRP) via ODIN, but nothing worked. Oddly enough, I never received the emmc error that I have read about. Also, in the few times that my phone booted normally, I even loaded the Wakelock Power Manager app, set it to partial wakelock and my phone STILL continued to bootloop. As a last resort, I bought a new battery, but the reboot problems continued in Android 4.4.4 Kitkat, 6.0 Marshmallow, 7.1 Nougat and 8.1 Oreo ROMS. Well, here is what finally helped me to get my phone back operational. I had a backup ROM from a previous install and a TWRP flashable version of the same ROM on my SD card (in case the phone did not stay on for the full restore). I put the phone into a ziplock bag into a freezer for about 20 min. (thankfully this time TWRP stayed on long enough for me to do the following):
1) copy all the files I wanted to save from internal storage to a computer.
2) performed a full wipe (Dalvic, Cache, System, etc. Like when flashing a ROM, but this time also internal storage. Note: Please do not wipe both internal and SD card, as you may have a difficult time trying to load the ROM file back on the sd card (assuming you don't have a card reader).
3) After wiping, I was able to restore my stock ROM backup (or you can just flash the stock ROM).
I can't be 100% sure, but I think my wiping internal and then flashing the stock ROM finally did the trick. Since this morning, the phone has been pretty much back to as it was before. In either case, I'm sharing this with the hope that it helps someone else.

Unable to flash stock firmware

Hello, my SM-G935A is rooted, and I have 2 issues with it. Firstly, I'm unable to receive texts or phone calls (I can send them), and I've tried a factory reset and I even got a new SIM, but nothing worked. I think if I flash stock firmware, it might fix the issue. Second problem, when I go into download mode and select my AP in Odin and press start, my phone gets an error and Odin freezes at Initialization.
Any help would be appreciated. I would prefer to fix the texting issue, as I don't want to return the phone to ATT. In either case, the Odin issue needs to be fixed

I'm having a similar issue. This afternoon, 2 apps threw errors and closed. I rebooted, which apparently was the wrong thing to do. The reboot stalled on the AT&T logo and stayed that way for 5 min - the unit became very hot & the power button did not respond, even while holding it down. I got into recovery, cleared the cache and factory reset, then rebooted. The unit came back up and started reinstalling everything. I took it back down into the download status and attempted to reload 935x via Odin, only to stall at "initialzation" [sic] as you did. I got out of that after waiting for some sort of response. SuperSU was still in my apps as was Root Checker. Root Checker indicates the system is rooted. SuperSU indicates it needs the binary updated. BusyBox and TiBu indicate they cannot find root. I deleted all the root apps and tried reinstalling root via adb which completed successfully, but the same outcome with all the root apps. So I'm not sure if I'm still really rooted as Root Checker claims, or not.
EDIT: I just saw that I have 2 "Knox Settings" apps. Clicking on either returns, "Unfortunately, Container Agent2 has stopped."

use the odin from the stock firmware thread to flash it again. if it fails you can flash the u firmware and then the stock again. then you have to use a different odin if you want to flash the root api file the one you flash the firmware with wont work. also there is help in one of the threads about fixing the volte problem so you dont have to turn it off to get calls. i didnt have to do it as using the odin i mentioned fixed it for me when i came from the u firmware.

did you have any problems with the u version of the s7 edge firmware, like the fingerprint scanner not responding? i am on that version and cant get any odin version or any version of s7 edge g935a firmware to flash, tried unrooting and was forced to use the U version of the s7 edge firmware, everything works except the fingerprint scanner, cant get back to full stock firmware, need help!

im having the exact same problem, when i put my phone into download mode and flash the stock at&t firmware, Odin get stuck in "initialization" and my phone screen displays and error message.

Same stuff was happening to me, I went back to stock and took the update. When your phone stops working as an actual phone, it's time to roll it back.
I played with it for a week and my phone was so freaking hot (with hot weather) equals a wait and see if this gets more stable in the near future. I did use the Odin 3.12.3 mentioned by King James III. Honestly, I did so many things to get it back to stock I forget what actually worked (it was the wee hours of the morning and I was spent). Don't give up guys, it will and can work.
edit: It may be as simple as not right clicking Odin and running it as Administrator.

I used Odin_v3.12.3_Patched_SHA256 to flash the 935U Firmware then used Odin3_v3.11.2 to flash the June Firmware release.
