SM-J500FN: Bootloop at Samsung logo after flashing stock rom 6.0.1

[knipsmoped]

Please help me out guys

I installed twrp pro 3.2.1-1 (https://forum.xda-developers.com/galaxy-j5/development/recovery-recovery-pro-galaxy-j5-2015-t3728264) on my J500FN (stock rom v6.0.1). It supports AROMA file manager. With twrp pro i installed [ROM][J500xx][TW-7.1.1][v5.0] SEPerience-ROM A8 2018 Port (https://forum.xda-developers.com/galaxy-j5/development/rom-sep-8-5-galaxy-a8-2018-rom-t3796971).

The ROM also started and ran without problems. Since I didn't like it, I installed Odin again with stock rom 6.0.1 (four-part version). I paid close attention to BL AP, CP and CSC. Odin reports sucessfull 1, failed 0. But now my phone still gets bootloop at samsung logo. I also tried v5.1.1, but bootloop at samsung logo here too. But it is the right firmware (SM-J500FN_1_20190207155114_slzx5q4t70_fac.zip). Exactly the same with stock rom v5.1.1.

I am at the end of my knowledge . Please help.

Try rebooting to stock recovery and do a factory reset. Your data should have already been formatted by installing stock theough but just in case try this

When starting stock recovery, the message "installing system update ..." appears and shortly thereafter "no command.", before the recovery menu appears.

I did "wipe data / factory reset" and "wipe cache partition" and then "reboot system now". Unfortunately a bootloop at the samsung logo ::crying:

I don't understand what I did wrong. I have already flashed some Samsung smartphones with new firmware. So far I always thought that flashing the stock rom firmware can fix everything.

That should be the case. Try a different version of Odin perhaps? I know people have issues with certain versions on certain devices

I tried the following odin versions:
Odin3 v3.09
Odin3 v3.10.7
Odin3 v3.11.1
Odin3 v3.12.5
Odin3 v3.14.4
Always the same
After flashing, Odin reports suceed 1, failed 0.
The automatic restart begins with the Android logo and the messages "installing system update ...", "erasing", "installing system update ...". Then the device restarts up to the Samsung logo and then goes into bootloop.

I also always did "wipe data / factory reset" and "wipe cache partition" and then "reboot system now" via stock recovery, just before I rebooted the device. Alwas the same. At samsung logo bootloop.

I have attached 2 screenshots of the flash process (without errors).

I am at a loss. What else could be the reason? I hope you can give me more tips.

Update, second attempt.

I've added a few photos as I may be missing an important clue.

I don’t know, what i do wrong.

With ODIN v3.14 I flashed the right stock rom (picture 1) back, which was previously installed (picture 2). I paid close attention to BL AP, CP and CSC. Odin reports succeed 1, failed 0 (picture 3). But now my phone still restarting on samsung logo (it isn’t bootloop, sorry for the wrong description).

If I try to enter stock recovery - first it appears "installing system update", then "no command" and then it enter the stock recovery. I did „Wipe data/factory Reset“, „Wipe cache partition“ (picture 4) and then „Reboot system now“ (Successfully verify for dmverity hash tree). But no success. After the samsung logo lights up a few times, the smartphone restarts.

I installed again TWRP pro 3.2.1-1 (https://forum.xda-developers.com/gal...2015-t3728264).

• TWRP pro – WIPE data, cache and dalvik. Okay.
• TWRP pro – INSTALL [ROM][J500xx][TW-7.1.1][v5.0] SEPerience-ROM A8 2018 Port (https://forum.xda-developers.com/gal...rom-t3796971)- without any changes. Okay.
• TWRP pro – Wipe cache/dalvik. Okay.

With TWRP - "Reboot System" I restarted the smartphone

• After „Reboot System“ – no restart on Samsung logo; the setup process started and after selection language and beginning selection WLAN, the system reported stopped something and then restart
  
• After a short time the setup process started again – selection language, selection WLAN, selection terms and conditions – restart without any report
  
• After a short time the setup process started again – selection language, selection WLAN (was already set up), selection terms and conditions, Searching for updates …. Finished. The desktop appears. But then without a reason – restart
  
• After a short time the setup process started again – selection language, selection WLAN (was already set up), selection terms and conditions, Searching for updates …. Finished. The desktop appears. But then without a reason – restart
  
• After a short time the setup process started again – The desktop appears immediately. And I can work with the smartphone perhaps 10 minutes – but then restart without any report

Can the error be further narrowed down? Is it a hardware or a software problem?

And the sim-card is not recognized.

I am at a loss.

And i don't know, why the pictures are not displayed

I bought a used motherboard. Problem solved.
