[Q] 915FY Stuck Not Booting

Hi All,
I have a Note Edge 915FY. Tried to upgrade it to stock 5.0.1 via sammobile.com
It is now stuck. It just shows the Samsung Galaxy Note Edge screen and then flashes to "Recovery Booting" and just stays stuck there! For hours!
I have also tried to download 4.4.4 from sammobile.com and flash that but same thing happens. I cannot go into recovery, only into download mode.
I also tried to root it using CF-Autoroot but that failed.
Furthermore, I have tried flashing CWM and TWRP but both do nothing.
I am absolutely stuck! And I really need help!
PS: The phone has no warranty now, so I have no fallback! Please HELP!!!!!

I didn't have any luck flashing CF-AutoRoot when I was on Lollipop, I used CWM and it worked fine.
If your'e stuck go into ODIN mode (Power, Home + Down Vol) and then click up when prompted,
make sure your pc has samsung drivers installed
Download the stock 5.0.1 BOC2 ROM from this XDA page
http://forum.xda-developers.com/note-edge/development/rom-stock-tw-lollipop-t3019721
(You can easily up to BOC6 or a hacked rom later)
Make sure to set Odin as shown in the picture from that same url above
http://dl-1.va.us.xda-developers.com/3/1/4/6/2/6/9/odin.PNG?key=DHp6BTdAsBVpoENIbV4DMw&ts=1431888807
This should work without any issues, I spent some cycles getting bootloops via cf-auto root and some funny ROM behaviour, I was always able to
use this to get me back to stock, root using cwm method then deploy whichever debloated rom you like !

Did you solve?
Try this (It works for me when my Note Edge was bricked):
On samsung kies 3 select "Tools --> Firmware Upgrade and Initialization" and follow the instructions.
It will ask for phone model (SM-N915FY or other) and for Serial Number S/N, this number is indicated under the battery (make attention to insert the number near S/N not near SSN).
After this It will ask to connect the phone in Download Mode and after it will start to download the firmware (more than 1GB) and will start the installation.

Boot into recovery , power + button + sound UP and clear cache and all reset.
Re do lollipop and you should be fine.
Happened to me but i worked it out after the panic stage....

I have tried this but weird enough for me, after I input the model number followed by the S/N number in Kies, I got a message "Initialization is not supported for SM-N915FY"
Its kind of fishy since the S/N input only appears after I gave Kies the Model number. If N915FY was not supported, why would they make me open up the back cover and look up for the S/N, make me type it letter by letter and then tell me 'Ok, no luck for you!'.
Any explanation and/or solution for me please? I only have 14 days of extensive researching experience, still left with a 'baseband unknown and null imei" note edge with no prior efs backup .

I think we got the same problems bro, i was very proud note edge user till two days a go, when sudden problems start to happen like restart, slowdown, loop, freeze and shoot of, later no more reboot from system menu that it just shoots of, and then latter hard to start, i had to take out battery and push start + home + volume down buttons about one minute and put back battery just to bring in to download mode and then volume down to start the in to system, and after screen is off it shots down again and again, and last time i put in to freeze to start it to see any missed calls or messages, but sens last night no way i can start any more!
I used to update apps from google and samsung store, and i em curious at this latest update, overnight was lot of data use, even in settings it was setup not to sync any data and not to use any data in background, only Viber app, so i assume there most have been sent to our phones some malware update to brick our old lovely phones, it is very possible.
Now, all i can do is to go to market to find broken screen note edge to purchase and replace motherboard, and i hope i find one not sim-locked.
So try to use Odin v3.07, and download the firmware from here https://www.sammobile.com/samsung/galaxy-note-edge/firmware/#SM-N915FY ans flash it, hope you get back your phone, and if you need to root it, use TWRP v3.02.tar flash with odin to...so the rest of procedure i guess you know!

Today i found on local phone shop+ service one note edge with a bit broken screen, but it did start and stack on kind of "recovery booting", i realized the service or the owner did try to flash sort of room on it but not completed, i bought the phone sm-n915FY model for 30.euro, and now i just transferred the motherboard to my own phone and flashed the TWRP v3.02.tar successfully and let it charge first, bcz there was only 05% battery, and later i will see if i can restore the twrp backup, and i will be careful with this update apps from google and Samsung store the gmail, androidwebsecurity**, maps and browser.
Well, my phone works now, it's just the TWRP backup is not working correct, even i modified folder of the backup, i had pssword in backup and now when i restore seek pasword, i type correct, but the phone did encrypt it. so i have to start with new room setup.

Samsung Galaxy S7 Bootloop/Recovery Mode

Model: SM-G930T (T-Mobile USA)
So today, I had an app not responding. I tried restarting my phone only to get stuck in a bootloop. My Recovery Mode isn't able to boot, but I can still access Download Mode. I tried to install the stock rom for my device to get the error with
"SW rev check failed FUSED 3 > BINARY 2"
"EMMC WRITE FAILED"
I'm thinking of trying to install the stock recovery, but apparently, I have to reinstall the stock rom, which I already did.
Thank you for taking your time to read this.

You should just put your phone in download mode and then run the samsung program, it will do everything else
volume down + power + middle button to go to download mode.

Whew, it's currently downloading applications for it. Thank you so much! I attempted to use a TWRP custom recovery for the T-Mobile USA version, but it looks like that was what blocked me out the recovery mode. Do you know of any custom recovery available for this?

Im not big on the phone extras (i have TWRP but not a big expert on it)..
basically this will factory reset your phone and make it working again, its up to you if you want to flash it again with ODIN and get TWRP on there.
I have a ton of issues after rooting my s7 exynos that I dont even do it anymore or remove bloatware. Something is clearly up with my device but im happy with the phone working, its ok if its a bit slower than it should be - for me.

You should read the s7 t mobile section before you damage your phone. If you go there you'll see you can't flash twrp on the g930t
It can be rooted but no custom recovery.

Thank you for responding. Yeah I couldn't get it out of the loop tried every version of Odin I could find used galaxys7root.com's firmware Sam's and one I found on here the only thing that wouldn't fail flashing was the boot loader with the modified odin

i tried to use smart switch but i dont know what my serial# is because i cant boot into android, am i missing something?

Can confirm this flashed fine on my "Three" branded [unlocked] UK S7. Thankfully, the ghastly Three branding has gone

S7 won't boot (Stays at the pulsating samsung logo)

Hello XDA friends,
I hope to find a solution for my problem with my Galaxy S7.
I've flashed the newest Version of Android with Smart Switch, but it won't boot to Android. It just starts "Samsung, Powered by Android" then switches to just the Samsung Logo then gets hot and after 5-6 Minutes it vibrates 2 times but nothing is showing on the screen except the Samsung logo.
I tried everything, rebooting it several times, multiple tries with factory reset. Nothing helps.
Hopefully you guys can understand my broken german english.
This is what the Download Mode currently says:
ODIN MODE
DOWNLOAD SPEED: FAST
PRODUCT NAME: SM-G930F
CURRENT BINARY: Samsung Official
SYSTEM STATUS: Samsung Official
FRP LOCK: ON
Secure Download: Enabled
WARRANTY VOID: 0
RP SWREV: B:1 K:0 S:0

I have a similar issue to this, no fix found yet though.

Flash stock with ODIN 3.12.3

^^^^ Flash stock OS with Odin, if Odin returns with FAIL straight away go into TWRP and format System and Data then flash stock OS

I already tried 7 different stock roms, all have the same problem.
And I cant flash TWRP because the FRP Lock is on. And because I cant boot into Android I am not able to switch it off.

So far, i've tried these firmwares:
Smart Switch - Nope
SM-G930F_1_20170203142713_MOB_fac - nope
SM-G930F_1_20170210110639_6j1nt9xw0b_fac - nope
SM-G930F_1_20170418223200_pf0e8ktcz8_fac - nope
G930FXXU1APB4_G930FVFG1APB2_MOB - nope
SM-G930F_1_20170329175552_qghvj8op9t_fac - nope
SM-G930F_1_20170317121226_ipt5jsw6zo_fac - nope
And on every firmware there is the same problem. Pulsating logo, but nothing happens except the phone gets warm for some time and then cools back down.

I see all the firmwares you have tried have been from 2017, so I assume are all Nougat?
Tried an older Marshmallow firmware?
This one is BTU Unbranded United Kingdom MM for G930F
http://updato.com/firmware-archive-select-model?record=2877DF1921A611E6949E0CC47A44B7B2
Also have you tried using CSC rather than CSC_HOME?
Are you using the correct CSC for your device?
Have you tried checking Repartition in PIT section of ODIN?
Finally are you using ODIN 3.12.3 minimum version?

Tried an older Marshmallow firmware? Yes (Stays on the "Samsung powered by Android" logo)
Also have you tried using CSC rather than CSC_HOME? Yes
Are you using the correct CSC for your device? Yes
Have you tried checking Repartition in PIT section of ODIN? Yes
Finally are you using ODIN 3.12.3 minimum version? Yes
So far, no success

Have you got access to a different PC to flash from?
And a different USB cable to flash with?
If not a different PC, try a different USB port, if using 3.0, try 2.0 and vice versa

Tried it on a different pc and on different usb ports, I even tried multiple versions of the rom on multiple ports.
Still no luck

Sounds like it might be time to RMA unfortunately

I can't send it back, since I got it from a friend and he had a screen repair from a non-samsung partnered shop.
So the warranty is void :/

I have had this problem in the past.
You need to download Samsung KIES 3
(Version 3.2.16084-2)
Select Firmware Upgrade & Initialization from TOOLS at top of APP.
MAKE SURE YOU CONNECT AND DISCONNECT WHEN KIES TELLS YOU TO.
Make sure you have your exact model (example: my model is SM-G930FD)
Make sure you have your Samsung Serial Number (example: NOT ACTUAL S59K432SLQF).
IF YOU DON'T HAVE SAMSUNG SERIAL NUMBER, YOU MIGHT HAVE IT ON YOUR RECEIPT OR BOX.
IF NOT, PERHAPS YOUR CARRIER CAN GIVE IT TO YOU.
DON'T WORRY ABOUT ANY SMALL SCREENS THAT POPUP AND SAY ANYTHING ABOUT NOT BEING SUPPORTED -OR-
THAT SMART SWITCH IS FASTER.
Eventually you will get to a screen that says
"The device can be initialized to its original settings.
All settings and data will be deleted, and the latest software verison will be installed.
Do you want to proceed with the firmware upgrade and initializastion? (OK CANCEL)
The app will download the firmware and then apply it to your phone.
Do not touch the cable or the phone while the process takes place.
When done, your phone will reboot as a new phone.

I did everything as You and Kies explained, sadly tho this also does not work for me....
This is so weird why is it constantly trying to boot and get stuck at the logo? :/

When you are in download mode, press and hold down volume, Home button, & Power key. When phone goes dark, switch from volume down to volume up, & keep holding power & home. This might get you into stock recovery.

You may be able to find a local repair shop by searching through Google. OR-you can try searching for craigslist. Org and your city. Then lookup repair of your phone.

Have you tried flashing each section of the ROM one by one and attempt a boot after each?
Can't really think of anything else, it sounds as if the internal storage is having problems, as mentioned above, a repair shop could be your only hope now, but I already know they'll tell you the motherboard is faulty (even if it is not) unless you know of a reputable shop that doesn't BS customers for £

Try calling Samsung and ask them how much to reflash out of warranty.
It shouldn't be that much....

In a boot loop after flashing device... what next?

I inherited a Galaxy S7 from my brother after he recently passed away. He was with T-Mobile, so it's a G930T (I have the original box, too, which has come in handy). I brought it back home with me... to France. I figured I'd have it unlocked and replace my old smartphone with this newer one.
Since I didn't know what his pin was, I did a factory reset... and found myself stuck in FRP!
At that point I called T-Mobile and was able to have myself added as an authorized user on my brother's account. They gave me the pin (too late! gah!) and unlocked the phone on their end, as it had been fully paid for. But as far as the FRP thing they were unable to help.
After a lot of googling, I found a bunch of how-to videos explaining how to bypass FRP, I thought I was in luck... except none of them worked for me. Then I came across a comment stating that flashing the device might do the trick. So I decided to try that... but now I'm locked in a boot loop (on the Samsung Galaxy S7 screen that keeps flashing on and off).
Here's what I did, step by step:
1) I installed Odin 3.13.1 from samsungodin.com
2) I downloaded & unpacked a stock ROM from sammobile.com, more specifically this one:
G930TUVS8CRJ1 - GALAXY S7 SM-G930T TMB USA (T-MOBILE)
3) I connected the phone to the laptop
4) I ran Odin and selected (with the AP button) the AP_GS30T* file & hit "start"
Odin said PASS! and I thought all was good... except it wasn't.
So I went googling some more and found a great page... which I am not allowed to link to yet, apparently, but it's on thedroidguy's website.
Only problem is that I can NOT get into the Recovery Menu. When I try the procedure (Home+Volume Up+Power) all I get is "recovery booting" in a bright blue font and THAT starts flashing on and off instead of the Galaxy S7 screen. If I redo the same button sequence, it just switches back to the other screen.
The ONLY other screen I can get to (unless there's another trick I haven't heard of yet) is the blue 'Warning' screen from which you can install ROM's (Home+Volume Down+Power).
So I tried to reinstall that same ROM two other times. First because I wasn't sure if I'd ran Odin as an administrator the first time around, figured that might be the issue, but that didn't change anything. Then I gave it another shot, this time using the phone's original USB cable (I had initially used mine), hoping that would make a difference... but of course, it did not.
So... is there anything I can do at this stage? Did I maybe go for the wrong ROM? Is there another one I can try?
I just hope it's not permanently bricked :-o

So I managed to unbrick my device, yay me! It took me some time to figure it out, but the solution was quite simple. Up until that point I had only been flashing the AP file alone. What fixed my problem was to also flash the bootloader (BL) file. This got me out of that boot loop.
I still haven't managed to bypass that annoying FRP lock, though. Every technique I've tried has failed.
On the plus side, I'm becoming an expert at flashing :-o
I just came across a method that, I think, could work: flash the factory combination file, enable usb debugging, then flash the regular firmware (with all files except CP).
My problem is that I can only find ONE combination file for the G930T but it doesn't match ANY of the firmwares available on sammobile... is this a problem?
The filename is similar to the v6 firmwares, only the last 4 characters don't match.
The other issue is that none of the v6 firmwares will flash on my device (they all fail pretty quickly while going through the AP file)... will using the combination file fix this?
Any thoughts or suggestions would be greatly appreciated.

Stock-S7 freezes on startup after Oreo-update (full wipe, different stock ROMs)

Hi there,
I am trying to repair a stock S7 (G930F) which freezes after an OTA-update. About a year ago there was a similar problem, which I solved by flashing an older firmware and telling the owner not to do the update again. Now the update was done again and this time Odin does not let me downgrade due to "KERNEL REV. CHECK FAIL".
The freeze appears 10 to 20 seconds after reboot. The phone freezes completely and after 20 seconds it restarts. That's not enough time to complete the initial setup or anything else.
I tried many different stock ROMs, full-wipe by stock-recovery, re-partitioning with Odin, safe mode, all with and without SD-card, SIM-card and cable plugged in.
I can't try custom ROMs or TWRP due to the FRP (force reset protection). To disable this a have to login with the previous Google-account... this is not possible within time before the phone freezes. My last idea would be to search for a method to remove the FRP in the darker pages on the web and then using TWRP and custom ROMs. Or the dangerous NAND-Erase in Odin (I have no EFS-backup)?
Any ideas except buying a new one?
Thanks,
Philipp

Philip, it helps if you let us know what country your in.
Anyway the solution to your problem is pretty straight forward, you just need to flash the latest firmware for your region with Odin. No need to mess about with TWRP at this point.
Official firmware will contain a copy of the stock kernal which will also be installed when you flash with Odin 99% of the time. If for some reason the kernal is not flashed (it happens) and you continue to get the reboot issue then you will need to flash the kernal seperately first with Odin then the firmware afterwards.
The issue with the FRP lock will remain after this but should allow you to unlock with google email and password.
So we're talking, downlaod mode, flash official fimrware and go from there.

Hi cooltt,
thanks for your reply. Unfortunately I already tried many stock ROMs. I am from Germany, so of course DBT first (G930FDBT7ESL9), then VIA (Telefonica) and VD2 (Vodafone) since they had higher build numbers. Desperately I also tried other versions to get it running somehow (for example the Polish G930FPRT7ETA9). The kernel was successfully installed with all ROMs.
I was very confused, that this does not work. In my understanding this can not be explained. After full wipe/repartition and flashing stock it should be as "stock" as it can be (and everyone should have these problems). Either all these ROMs I tried are broken, some hidden things like EFS are heavily broken or there is a hardware issue with this phone which made absolutely no problems with Nougat but now with Oreo.
Bootloops after OTA (which are dirty) are usual, but this is driving me crazy. I can not believe in a hardware issue since a very similar problem appeared one year ago with Oreo and there were never any issues with Nougat. But if it is a software problem, more users should have this...

Hello Philip this might be a long post
What firmware was on the device before the problem started? Was it branded or unbranded?
Are you sure the phone is a genuine G930F or a phone that has been turned into a G930F by flashing that firmware in the past? You can check by looking at what the phone model is at the top left corner of "Download mode"
Where are you getting the other firmwares from?
I've attched Samfirm tool which will get the latest firmware direct from Samsung servers.
1. Unzip file
2. Right click on SamFirm application and run as admin.
3. Check "Auto" & "check crc32" & "decrypt auto"
4. Model is "SM-G930F" type it exactly as shown without quotes
5. Region is "BTU" . Offically UK with all EU language options but also additional files which will fix firmware install problems.
6. Press "check update" then "download". It will decrypt automatically and you will have a zip file with 5 files inside(BL,CSC,AP,CP,CSC_HOME) choose CSC not CSC_Home when placing into Odin. Place all other files in right place.
Odin attached is version 3.13b patched. This version of Odin will ignore lots of miss-match device errors and just install the above BTU firmware.

Hi cooltt and thanks for your help!
Unfortunately the BTU-ROM did not solve the freeze-reboot-problem but led to another: After flashing the phone gets stuck with a blue screen "Erasing". After several hours I force rebooted and now it is showing a similar screen with "Error!" and a percentage which is increasing to a random number from 0% to 12% on each boot. On first boot it shows the boot screen ("Galaxy S7"), then "Installing system update" shortly and then "Erasing". After force-reboot it shows boot screen, "Erasing" then "Installing system update", both for a very short time (sometimes misses "Installing...")
As suggested I used SamFirm to download the newest BTU-ROM (SM-G930F_1_20191218140415_dgobhw6g3v_fac; G930FXXS7ESL5/G930FOXA7ESL5/G930FXXS7ESL5/G930FXXS7ESL5). I just ticked F. Reset Time and Reboot. Re-Partitioning did not change anything. Using Odin v3.13.1 does not make a difference. The other ROMs, like SM-G930F_1_20191226131628_8ds2p6kf0v (G930FXXS7ESL9/G930FDBT7ESL9/G930FXXS7ESLA/G930FXXS7ESL9) which I downloaded with Frija (should do the same: download enc4-files from Samsung and decrypt) make the phone going to the initial setup fine, but with the reboot-problem. Tried also with Odin 3B patched.
At this point I was going to write, that I could not access the recovery mode with the BTU-ROM but just now I started it unintentionally when looking for the sequence of screens showed on boot. So I used my chance, made a full wipe and screenshot. After this the phone booted until the glowing "Samsung"-logo appeared. Then rebooted and went to initial setup (after "Androi"Installing applications") in German. The freeze-reboot-issue appears as with all the other ROMs.
The phone is certainly an original SM-930F as it was bought directly from a big, trustworthy dealer and then just used by my aunt. The only one touching it when problems appeared was me. There is SM-G930F printed on the backside and showed in download mode.

Hi Phill
The only options checked in Odin should be F-Reset and Auto reboot. Don't check any others.
The blue screen erasing and updating is normal after a flash with Odin, the phone will restart a couple of times, just leave it do it's thing for a bout 10 minutes or so. If it's any longer than that as you have mentioned then it's stuck as you've said.
So we're going to start from the begining again but do something slightly different.
1. Place the phone into download mode
2. Run Odin but uncheck "Auto Reboot" so the only option checked is F-Reset Time.
3. Use whatever firmware you want, BTU or DBT the latest version. Make sure files are in the correct boxes.
4. Connect phone and flash with Odin, wait until Odin says "succeed 1" and "dissconnected" . It may even say "pass" in green, not important but "succeed 1" is important.
5. Your phone will show the bar and do not disconnect. So....disconnect from laptop / PC. The screen should remain "do not disconnect".
6. Hold volume down+home+power (in that sequence).
7. As soon as the screen goes black move your finger to volume up, while still holding down home + power. You are trying to get the phone into Recovery mode as you said earlier.
8. The option to choose in the recovery menu is "wipe cache partition" NOT "wipe/factory reset". I can see from your pictures that this option has failed because the FRP lock is still on!!
9. When you've chosen "wipe cache partition" then choose "reboot system now"
The phone should go through it's normal set up routine, erasing, update, installing apps etc, just leave it do this and hopefully the phone will boot then ask for the Google email and password which was used on the phone.
There are very few reasons for the phone to get stuck on boot....
1. Incorrect firmware,
2. Water damage
3. The phone has been Rooted with FRP lock on. It is very rare to be a hardware issue.
You should always turn FRP lock off and enable OEM unlock in settings before flashing to a phone. I know it's a little late for that but something to remember.
To check for water damage.
1. Remove SIM card and holder
2. Shine a light in the hole, you will see a WHITE sticker which turns PINK if water has ever got inside the phone.

Thanks a lot again for your great efforts!
I tried as you wrote but did not manage to start recovery immediately after flashing (tried >10 times). But after some while the BTU-ROM started and now keeps doing so even after new flash without wiping cache afterwards. Wiping data worked for me in past when I sometimes had enough time to enter Wi-Fi-password. It was saved even after reboot and away when I did data wipe in recovery. With the newest ROMs I never got beyond typing Wi-Fi credentials.
I cannot see a water damage. A root was never tried before (and OEM-lock and FRP were always on because stock, which is very bad now ). Would be absolutely no problem if this !#@*#% stock ROMs would work... TWRP installation was directly blocked when I tried my luck as last resort. I did not try other images.
Thanks nevertheless for your time and patience!
