[S6] Crashed and stuck in bootloop, please help! - General Questions and Answers

Hi guys!
I have a Galaxy S6 for 1,5 years now. I was on Whatsapp, and the phone got into the boot loop randomly. Everything is still original, not rooted or a custom firmware. Most important thing for me is to get my data back. The data is more important than the phone for me.
This is what I already tried to do:
-Got the battery replaced in a shop (they replaced it 3 weeks ago, so they did it again just to be sure...)
-Samsung Premium Service hooked it up to a service device, that would bypass the battery and supply it's own power. Still the same, and the guy told me the voltage was fine.
-Another shop reflashed the firmware part with Chimera, he said that won't delete the data on the phone. Flashing was done, but still the same problem.
-I flashed the phone with Odin and the original firmware. First 5.1, but that gave me an error. Then I flashed the firmware parts separately, only sboot.bin and cm.bin gave me an error.
-Later I flashed the phone with Odin and the newest 6.0.1 Samsung firmware. I think the shop before flashed it also with Android 6, that's the reason why 5.1 gave me an error. Anyway, flashing to 6.0.1 with Odin was successful, but the phone still has the same problem.
I can only enter Downloading mode on the phone. Recovery mode doesn't work. USB debugging is not enabled.
Any suggestions or ideas? Any help would be very much appreciated. The data on the phone is really important to me.
Thanks a lot!

Thanks for your reply, but I can't go into recovery mode. Boot loop and download mode is the only thing it still does. I can't even turn the device off, need to wait for the battery to empty.
I was checking out that thread, they are talking about flashing the PIT and param. Do I have any chance with that? I just need to acces my data....
Thanks

[Completed] Formatting Samsung S3 Problem

Hey, so basically I'm in a situation where I have no idea what to do.
I recently just got a new phone, and am going to give my Samsung Galaxy S3, SGH-T999V model - from Wind Mobile to my Dad. Basically, when I first got the phone - a couple months after, I decided to try Rooting it, and I did, successfully. Since I didn't really know what to do with my rooted phone, I decided to unroot it - then tried rooting it again some months later, but it didn't work successfully. Basically my phone wasn't rooted, but I had the "Team-Win" recovery on it.
I wanted to bring my phone back to it's original state - and have the stock recovery on it. After some Googling, my solution seemed to be to flash the stock rom for the SGH-T999V model onto my phone using Odin. And I did that - and it worked successfully. But I still couldn't check for OTA updates or anything, it said my phone had still been modified in an unauthorized way.
Now that I need to give the phone to my Dad, I have to format the device and erase everything. This is where my problem starts. When I try to format it (using the Stock recovery), I see a bunch of error messages, with the Android logo falling down in a kind of dead way. I reboot my device, and nothing changes.
It still has all my data, and everything on it.
Sorry if this is the wrong area to post this (I'm relatively new to the forum), and if my problem doesn't make much sense - I've tried being as detailed as possible. Could anyone help?
Hi, thank you for using XDA Assist. Flashing the stock firmware should show you to get ota's. This should have everything you need,http://forum.xda-developers.com/galaxy-s3/general/samsung-galaxy-s3-sticky-roll-thread-t2344125.

[Q] Huge Problem (Build.Prop/Bootloop/Cant Flash)

Hi everyone,
Right I have a serious issue with a 4 day old S6 from the UK bought SIM-Free off Amazon.
My phone was rooted but didn't have ADB or any sort of custom recovery. I edited the build.prop file for the RAM management thing, and created a copy back up on my storage. I didn't like it too much, so I copied the back up over the edited one and restarted - phone went into boot loop.
I have attempted to use Odin and flash a stock firmware ROM (had to settle for a H3G variation because the XEU unbranded was off some download website that takes 10 hours to download). I went through all the steps with Qbking77's walkthrough with Odin and it came up that it failed at the end.
The phone then booted into the Emergency Recovery screen, and couldn't get back into Recovery (to do the Smart Switch recovery), and can only get back into the Download bit.
I've tried flashing it again, and no avail.
I seriously, seriously hope someone can help me out here, it's a brand new phone and I love it and I don't want to be left with a brick.
Thanks.
I was in the same boat, if you rooted and didn't trip Know, your best bet is the Samsung Store, they're all over the UK
Well an update:
After the third time flashing failed, I did a root via Odin which had previously failed, and it booted up, completely normal and set up the device as normal.
I have no idea how that worked - but it did. Probably tripped the Knox I think but it works.

I might have permanently bricked my phone

Hey, I made this account to ask this question I'm pretty desperate,
My phone was acting up (overheating, WiFi didn't work half the time), so I decided to reflash my cyanogenmod rom, me being the idoit that I am I didn't do a backup before formatting my phone, I tried to flash the zip file but twrp kept crashing, so the next logical step was to use ADB sideload to flash the rom, that didn't work as well as I expected either the install kept failing at 88% as I was rebooting the phone for yet another attempt, recovery wouldn't start at all, at that point I was pretty frustrated, so I decided to flash the phone back to stock touchwiz, I downloaded the stock firmware and attempted to flash it with odin, low and behold that didn't work either (auth error), I tried again multiple times with firmware files downloaded from different sites but those didn't work either, I also tried flashing stock PIT files to no avail.
So here I am at 5 am with a bricked phone and 8gb of tar files on my desktop any help at all would be greatly appreciated.
Thanks in advance.
i know this thread is old, but can you get to download mode still?
What's the model and type of phone is this ?

S6 SM-G920f stuck on samsung logo after trying to install xposed framework

hey all
I did a basic root on my samsung galaxy s6 a few days ago. just installed superSu and gave me root access. after that I installed TWRP which I then used to try and install the xposed framework. From then on my phone is stuck on the samsung screen saying kernel is not seandroid enforcing. I downloaded the stock rom for my phone (sm-g920F on 6.01) and attempted to flash it via odin 3.07 but it always failed after the sboot.
i have searched to try and find a solution but nothing I can find will work. can anyone help?
so i got my s6 working after flashing a full stock firmware i found via a link on this forum (i forget which one...sorry)
it gave me BL_G920FXXU3DPBG_CL7086820_QB8626574_REV02_user_low_ship.tar.md5
AP_G920FXXU3DPBG_CL7086820_QB8626574_REV02_user_low_ship.tar.md5
CP_G920FXXU3DPB6_CL7086820_QB8569466_REV02_user_low_ship.tar.md5
CSC_BTU_G920FBTU3DPB1_CL7140831_QB8460122_REV02_user_low_ship.tar.md5
it also recommended that I flash the pit file ZEROFLTE_EUR_OPEN.pit.
this was all done via the latest version of odin. initially, the flashing failed at cm.bin so I reflashed omitting the bootloader and all seemed to be well.
My phone set up fine and then I realised that it will not recognise my sim...or any sim for that matter. in settings under sim card status...every entry is listed as unavailable. IMEI is unknown as is baseband version.
i realise that I have obviously messed up big time with the initial flashing (uhuh....backup...backup....backup) but I would really like some help to get my phone back up and running as a ...well...phone.
any help or suggestions would be most appreciated.
thanks in advance x

Try smart switch. Not sure if it could restore the imei but it could bring the phone back to original csc when you bought it.

Samsung Galaxy S4 "I9505" Black Edition Firmware Flash Issues

Greetings.
I didn't post in very long time on this forum,since I could handle most of the problems on my own,now I need some andvanced tips and advices,so I'm reporting in.
I bough myself a Samsung Galaxy S4 Black Edition last year here in Bosnia and Hercegovina.Beautiful phone,never got a scratch on it,It had Android 4.2.2 Jelly Bean out of the box but all of the features from basic S4 except one,it couldn't update firmware to Lolipop 5.0.1.
That used to bother me,since I had much older devices that supported JB and this phone was just special,enough that I couldn't let it be my daily driver having unused potential,so i threw myself at work(which will later prove a very bad decision).
I checked for OTA updates in the settings and that option would litteraly do nothing,providing no info,or searching for new updates.
Smash that Build number,got into developer mode,toggle USB debugging,Install Kies on PC,run it as Admin,download latest drivers,connect the device,Firmware update asks for IMEI and s/n,type them in,says to check my s/n and IMEI,do that few times under different compatibility options,still the same.
I thought it must be something bad with data/catche so i reset to recovery mode and wipe them out,setup the phone,enter the OTA update for second time,it shows me "Your device have been modified, Software updates are not available", check device status and it states "Samsung",after several attempts it sometime said "Modified" sometimes "Samsung",Kies didn't recognise the device through all this process.
I was already lost here,but I thought,hell Kies isn't working,neather is OTA,i could flash using Odin,that might do the trick.
Went to Sammobile,downloaded latest drivers and Odin,found one Firmware that I though was compatible.,unbloked them in properties and set to rin as Admin.
Uninstalled Kies and checked for leftover drivers again,and it was all clear to go,ran odin,mounted firmware,set device in download mode and started flashing but Odin poped out "complete(write) operation fail" error.
Didn't want to try fixing it,went straight back to SM and downloaded two other firmwares,one said "complete(write) operation fail",and the other "Re-Partition operation failed",so I thought Odin was bad,since I checked on two PC's with several USB ports.
Download two more versions of Odin and find a stock s4 PIT file here somewhere for repartrition error.
Extracted everything,unblocked and ran with privilegies,same thing on both Odin versions,except that only Odin 3.07 could flash the pit file alone with no problems it passed.
Next time i ran download mode i tried to flash the firmware write fail came up again,extracted recovery and flashed it alone,worked like a charm,so I tried flashing once again,it proceedes a little further with same write error.
Reset the phone to wipe data and catche and it goes into "Firmware Upgrade Encountered An Issue Error",Install kies,it still doesn't recognise the phone.
Out of option right now I go for search of alternative recovery software,and I found the famous "Dr.Fone" (how stupid I was to not read all those,"if it wasn't for this software my phone would die" comments)
Installed it,ran recovery my phone shuts down and displays "set warranty bit: kernel message",from this point nothing works except recovery mode,so I install CWM recovery and flash a Custom ROM,now only this option that sets my phone in working order and I want to recover it's Firmware back,Anyone that could help me with this issue,or had it solved before?
Atleast give it a try.
this amount of pain can't be titled

Day#4 Fail compilation
I see that this gets no response,but I'll continue this thread just in case I fix this and somebody else gets into same problem themselves.
I mentioned before that I somehow flashed custom ROM over CWM and that helped my phone boot into working state after bootloop error caused by greatest Android software there is on the internet,the legendary "Dr.Fone"
The Custom rom used was "[OFFICIAL][i9500][5.1.x] CyanogenMod 12.1 for Samsung Galaxy S4 [NIGHTLY]" From xda user: Alberto96 (thank you friend).
After several other failed attempts of implementing Stock firmware on this bricked device over the PC,I got to the point where I think that it's literally imposible to make it work since I tried so many ways and patterns of installation with no difference in the outcome results whatsoever.
I took a moment to rethink my strat over this and googled other ways of flashing that firmware without using PC.
Found 2 possible solutions that I'm trying to make use of,first is Odin Mobile and the Other is FlashFire.
Since both require rooted devices,finding way to root bricked S4 wasn't a very pleasant experiance,since flashing SuperSU through CWM recovery didn't work,Odin managed to flash me nice Autoroot from Chainfire over the custom ROM I installed before,I found a problem even there since the I9505 autoroot wouldn't work,the custom firware had changed the phone model to I9507 that I downloaded the Autoroot for,was a confusing issue,but I managed to root it anyways.
Page I used for this purpose was Chainfire Autoroot database(sorry if I'm violating forum rules but I think this could be left here without further discussion about it).
After rebooting the device I downloaded Rootcheck software along with SuperSU and FlashFire which confirmed that it's fully unlocked/rooted.
Now I'm recharging my phone so I can later tonight go ahead and transfer firmware to it's SD card and try to flash it once again with FlashFire,last option I'm thinking of as of now if this wouldn't have any progress is to download Odin mobile and try another flash,I'm running out of ideas on this one.
Sorry for the long posts,but these get no respose so who cares.
