The endless restart - A G920V story

Hello guys,
This is my very first post in XDA, I've checked the forums for about 3 days in a row with no solution yet . As I am typing this I just finished my 3rd flash, with re partition checked and the proper pit file including the stock rom.
Let me share my story with you, I got this galaxy for a $100.00 deal and the only issue it had was a couple of restarts a day. This happened after my friend (who sold it to me) installed an app on it which I suppose was some kind of virus or recovery tool that got very deep in the phone. As the g920v comes with a locked bootloader that probably caused it. Since my friend isn't that tech savvy and the device was only showing software issues I decided to take it. It only restarts when it boots, it can stay in download mode or recovery mode for the entire day without restarting which is the reason I believe is nothing from the hardware. Prior to this I even used it for an entire day, stress tests with no restarts.
As the post states, I've tried everything guys :crying::crying: . Odin completes the flash with no errors but it keeps restarting on me, any ideas or hints? I was thinking about checking the "nand erase" option in Odin to make sure everything is gonna get installed from scratch but to be honest I'm not that techy and I don't want a brick . I've deleted cache and performed factory reset from the recovery mode with no success. Official solutions like Verizon Repair Assistant or SmartSwitch have not been useful either.
So far the only solution I see is going back to 5.0.2 which can be rooted ( but how if it restarts ) , I've heard rooting it can stabilize the OS in general but idk. Sadly I am not from the States to claim any warranty or some kind of fix which makes the situation even worse.
Please help
------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
UPDATE
Good and bad news guys,
I decided to flash again but this time checking repartition and nand erase all, guess what! Including the latest rom which is G920VVRU4BOK7 and the pit that you will find here:
sammobile.com/forum/showthread.php?t=30173
IT WORKED. No more restarts after a 3 day battle against this phone. Now the only issue is at the setup wizard -Phone Activation- which only stays in "Activating". I'll give it another 5 minutes. If it doesn't work ill factory reset from recovery mode along with erase cache which will hopefully work.
I'll keep updating the post for future references.
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
UPDATE
After a 3 day battle, I have won. I just needed to do a normal restart and now is fully functional. Everyone thanks and mark this post as solved :0)
Best regards,
Mandagio.

help!

Verizon G920V Will not boot up

Ok, I am a regular student here and have rooted several phones.
I rooted OE2 on a Verizon S6 with Ping Pong then I took the OTA from Samsung and lost root.
I then decided to try and return to stock after constant annoying update messages.
So I used ODIN to flash OE2 and all He++ broke loose.
I have not been able to boot up for 2 days. I have factory reset and reflashed with ODIN multiple times.
Sometimes it will go through optimizing apps and either shutdown or lockup, then it will quit after a while and not do anything other than the Samsung screen.
I cant boot into a real recovery and wipe cache because the firmware from sammobile.com doesn't have any recovery other than totally stock so, its applicable option is factory reset.
The blue light will pulse when not charging as well.
I am currently downloading the PD2 Firmware hoping it will work.
I would really appreciate any help, thank you.

It should work with the PD2 update. Once you accept an update you cannot go backwards in firmware only forwards. Every OTA is a bridge that burns as you cross it.

OK, will let see what happens. I tried the emergency recovery options on smart switch and it didn't work at all. It wouldn't go past recognizing the phone.
I was able to attempt to Odin flash pd2 this am but the pit files I got here reported as corrupted. Then I could no longer locate the pd2 file I downloaded after trying to flash it in odin. It was also from a link on here as well... So I will try again tonight.

Its been a rough several days..... I have uninstalled the kies leftover files via terminal, installed java updates, installed Heimdall updates, tried the one click Heimdall, attempted to learn what in the He}} the Heimdall program was asking me to load as I have no clue which files go where in the program, read tutorials on it.
I unzipped my PD2 (Verizon) file and it runs for a minute and then tells me the file is corrupt. It is the 3rd MD5 I have downloaded. I have no retrievable PIT file and have downloaded no less than 12 of them all of the USA VZW type and ODIN and Heimdall do not like any of them.
I really do not know what to do from here other than throw this POS in the lake. I am so far past frustrated I don't know what to do.....
Any help would be truly appreciated.......
Thanks!

I give up, not really any help here either so I just paid $200 deductible. Bummer.

Bootloop and can't reset

OK, my S6 (verizon) locked up today and immediately went into bootloop. I've tried wiping cache, i've tried wiping system/data, i've tried factory reset. It'll either lock up doing that, or it will complete and then go right back into the boot loop.
I tried using ODIN to flash the stock rom but i get the error: SW REV CHECK FAIL Device: 4 Binary:1
If I boot into recovery, it always starts at "Installing system update" (this was before I tried to update the stock rom or anything) and sometimes it will lock up doing that, sometimes i'll get into recovery, but as I've said so far nothing has gotten my phone into a useable state.
I tried KIES 3, but it just complains that my device is not supported.
Any suggestions will be hugely appreciated, this phone is only a year old and I really can't afford to replace it out of pocket.
Thanks!!

Kies3 doesn't supports S6 I guess. Use smart switch.
Sent from my SM-G925F

you can do emergency initialization with smart switch, instructions below:

Thank you for replies. Smart switch is telling me my SN is invalid, it is the IMEI number from the phone, and I've confirmed there were no typoes. I did finally get ODIN to work with a newer firmware, but after updating the phone just returns to a bootloop. I'm thinking its a hardware issue at this point.

Did you enter the model number correctly i.e. SM-G920V or so?. Not really familiar with smart switch. Used once without issue.

Yes, it accepted the model number and yes it was correct.

hi, did you try downloading the official 6.0.1 firmware the n flash it using odin. try flashing BL and AP, the bootloop cause might be because of your bootloader, imho

I had already tried flashing AP. After reading your suggestions i tried flashing BL as well. Now it gets to the red Verizon screen (which is new, it was bootlooping before it got there) but it just hangs there now. The "pluse" in the Verizon V logo keeps going, so its not completely locked up, but it never actually boots.
At this point I think i need to just replace it but I'll still accept any suggestions on things to try if anyone has any thoughts!
I appreciate all the help already provided.

im sorry to hear that mattbooty, lets not loose hope, how about downloading an old 5.1.1 bootloader and 5.1.1 official firmware for your phone variant. make sure that the bootloader goes to BL and the firmware goes to AP. , btw BL and AP should be both checked in odin before starting to flash the phone. Im sure this has something to do with bootloader img

OK, so after the last post, i did another factory reset from within the recovery options (this is after odin flashing BL and AP) and this time it got past the Verizon screen and to the new android setup screen!
I'm working on setting it up now and fingers crossed it doesn't lock up and go back into boot loop. I will update.

nice to know that my post was helpful mattbooty, btw did you downgrade to 5.1.1 just like what i've told you?

I didn't, that was using the 6.0.1 firmware. I had tried that firmware originally but was given an error "SW REV CHECK FAIL".
Prior to the phone bootlooping originally I had noticed it started locking up every now and then. Since getting it working again (for an hour or so) it has already locked up once, but it did boot right back up this time. Fingers crossed that doesn't mean its going to start bootlooping again soon.
thanks again for all the assistance.

[G930W8] Lost IMEI/Baseband, tried all methods, nothing worked

I was trying to install Ryzen ROM in which I made a mistake, there was no compatible CSC in is so I went on with UK's csc but it landed me corrupted IMEI/Baseband. Though I backed-up the EFS before installation. So I tried installing Stock back with Smart Switch and it gave me error while installation. Then I also tried installing stock with ODIN which also gave me installation error. I have 13 canadian firmwares and I tried each one of them, no one worked (some of them fail at 10-20% and some of them fail at 30-40%, no one ever crossed 40% and no one ever succeded). Then I installed Custom ROM and I also tried to restore CSC with Terminal command, which was successful but when I rebooted it was as is.
Can anybody help me get my IMEI/Baseband back?

Make sure you're using ODIN 3.12.3 or newer

Hey, i had a simular issue. You can try the samsung emergency recovery. If that doesent work you can better send it in for repairs. I also thought :"thats a easy answer but didnt solve my issue" but in this case its the last resort since i lost hours of time without being able to fix this issue. I tried several restoration methods resulting me in extra expensive repairs since i completely messed up the partitions because of trying too much.

Trying to root device gives me error message: "Verification failed"

I have rooted my phone many times before, but often times i mess things up so i would have to reset my phone to factory settings and do it all again and hope not to mess up. The rooting process was the easiest of them all. But today, i go a new message i had never seen before. I installed this https://download.chainfire.eu/929/CF-Root/CF-Auto-Root/CF-Auto-Root-herolte-heroltexx-smg930f.zip like i always do. And i have enabled oem unlock, and im ready to go. I might have forgotten something but i dont remember what. I rooted it and odin said "success", but when i looked at my phone i saw it told me my phone had been encrypted or something, i wasn't completely sure. It told me to put in my pin code and i thought "huh, maybe a new feature samsung added to prevent theft" I typed in the correct pin code, but then it failed and the only option was to factory reset it. I looked it up online, didnt find much information, except that if you clean partition cache, the problem is fixed. Well, not for me. I then decided, that i might aswell reset it. But the button didnt even work, i was like "what the **** even is this". I then went to recovery mode and factory reset it from there. And now im here, trying to figure out how to actually root my Samsung galaxy s7 android 7.0 phone without getting that stupid message again. I always rooted from 6.0.1 or 6.0, this is my first time 7.0, so please tell me what i have done wrong.

Try to root with flashing TWRP, and inside TWRP insall SuperSU
