[Problem] i9192 Constantly Rebooting (Not Solved)

[Yenien]

Hi everyone, I´m new on this forum!

I expect not to do newbie questions, but a have been reading here all the posts, FAQ and stickys without any progress =/

I have a Samsung Galaxy S4 mini GT-i9192, its NEW, but I dont know why its always rebooting. I flashed Android 4.4.2 like 3 o 4 times (The russian version in Sammobile) but I´m still having the same problem.

Any clue? Maybe should I try to flash Jelly Bean again? I would like not to **** the KNOX because I have 1 year warranty.

The moments when the phone works fine everything is 100% operative.. wifi, cameras, apps, SIMs, etc..

Thanks in advance!!
Regards from Argentina.

Edit: Can somebody move this to the Q&A, Help & Troubleshooting section? Ty

First don't downgrade to jb

Has you're baseband changed to the Russian?

Can you post a screen of your download mode

My baseband is I9192XXUCNG2, it hasn't changed in the differents ROMs I've tried so far, always the same. I'm currently using CM12 (lp) with similar experience (reboots along 3g mode), the module crashing is wcnss_8960, see an excerpt of this:
[I]....

[ 1299.625331] wcnss_8960: crash shutdown : 0
[ 1302.633144] Rebooting in 5 seconds..
[ 1307.642301] Going down for restart now
[ 1307.645322] msm_restart : clear reset flag

No errors detected

Sorry for the late reply, I'd it hasn't changed then.

Don't know what that error means but don't downgrade use only kk modems

To flash modem might take couple of flashes what works for me to change modem is this

Turn off your phone using power key and the popup menu
Enter download mode using key combination,
Use cp
Flash

Thank you fburgos quick question: what do you mean by "kk" modems ? any example ?

 

[fburgos]

Kk is KitKat, jb is jellybean
Modem/baseband only change flashing modem or official firmware, if you use CyanogenMod lollipop your modem won't change.

Quick search on Google about wcnss_8960 brings a lot of modem related random reboots.
Is your Knox flag is 0x0 or 0x1 (download mode or Odin mode)


Have you flash again stock any and try?

Well, unfortunatelly I took my terminal to the service support and they came up with ".... there is no other thing to do apart from replacing the main board..." :crying:

thank you for all your support here guys
