Hello, please i really need help
so tried good lock (Samsung systemUI), after that, the phone become unstable... I uninstalled it and the phone had a lot of fc of systemUI and other apps and random reboots, and sometimes it boot into recovery on its own sometimes into download mode, so i flashed another official firmware and did a factory reset , but no luck , then i flashed a ported Rom (Dr.ketan Rom) now my phone don't do a lot of fc and don't reboot into recovery and download mode on its own , but still having a lote of random reboots and a lot of freezes, any ideas guys? i looked everywhere but nothing
Same problem as you, but it's worst : I tried latest Good Lock 24.0.10 and after uninstalling it, I got a popup saying "SystemUI has stopped working", with black screen and can't do anything else than accessing menu with Lock Key (with reboot, shutdown buttons, etc.) :/
Tried to reflash ROM with ALEXNDR ROM for Note4 but same problem. Any solution ? I'm trying to restore Good Lock latest apk through flashable .zip to see if I can re-use my phone.

WEIRD/PECULIAR RESTART SCENARIO in my S5 GM 900F

Hi Guys,
I am facing a peculiar kind of problem in my phone (G900F) since yesterday.
What happens is that, if I tried
i) To restart my phone from the phone (reboot menu), the phone stuc in boot screen and then vibrate twice then after 5-10 sec the phone start rebooting all along once again with 2 vibration and this process keeps repeating until I pull out the battery.
ii) To access recovery (both hard- key combination or from reboot to recovery option in phone), the phone reboots and it stays in the initial screen for about 45 seconds and then the screen went black and freezes there until I pull out the battery.
iii) To access download mode ( both hard- key combination and reboot to download mode option in phone), there seem no problem.
The weirdest part is that, if I remove the battery for 5-10 min and re-insert the battery and do any of the above options; the phone reboots and i get the home screen loaded successfully with no problem . I can also get into my recovery after this 5 mins switch off just like the above. I also found the phone lags a bit in this home screen.
I almost did all the combination to get off this problem (stated below) but I keep getting this problem again and again.
I was in Sixperience v 3.1 with Pheonix Kernel v 10 and Philz CWM recovery and tried the below to try to fix the issue
1. Re-flashed Kernel from Recovery (Also, tried to re-flash kernel after uninstalling Xposed but no use)
2. Re-flashed Modem and Bootloader from ODIN once again (G900FXXU1CPF7_BL_G900FXXU1CPB8_MODEM_LTE.tar)
3. Reflashed ROM once again as a fresh install through Philz recovery.
4. Restore the cwm backup from recovery (which was backed up a week before.)
5. Flashed Samsung Stock MM ROM (G900FXXU1CPFH_G900FPHN1CPFD_PHN.tar.md5) as a fresh install.
After this stock ROM installation is done, the phone struck at SAMSUNG flashing logo and the blue LED keeps glowing for more than 30 mins)
Nothing works. ? Any idea on what is to be done to fix this issue? I am not sure, what i did but this problem keeps coming even after trying of all of the options since yesterday.
Please help to with your expertise.

G900F screen doesn't turn on after update

Hi,
After a LineageOS update, my Samsung S5 (G900F) was working and suddenly shouted down. I tried to restart it but it was booting in loop (always without passing through the first Samsung Galaxy S5 logo). As I wasn't being able to restart it I tried to fix it by installing the stock rom through Odin. It installed successfully and the phone rebooted with images in the screen. If I touch the phone I can hear the touch working and volume also works but I don't have image, not even while booting the phone.
Now, the only way I have to see image (in the download mode only) is to take off the battery for a few minutes and then restart the phone while pressing the download mode buttons.
I tried several times to install the stock rom through odin but the same thing happens everytime so I am still without image.
Any suggestions?
Thank you. :good:

Roms do not work

Good morning, I need help
I install the rom stock J500FNXXS1BQG1_J500FNITV1BPL1_ITV and on reboot gives me DRK error. To skip the problem I install the Twrp-3.2.1-1-j5nlte and on reboot after 10 minutes the phone only starts working that this rom weighs down the phone of useless applications.
I tried to flash several rom downloaded from your page but on reboot the phone display turns green and does not start and goes in loop. Only ROM that does not give me this problem and the MIUI-8-MM-8.5.5-J5xx but has a bug that you do not hear loudspeaker. How can I resolve to put a cyanogem miui or other type of rom?
