WEIRD/PECULIAR RESTART SCENARIO in my S5 GM 900F - Galaxy S 5 Q&A, Help & Troubleshooting

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.

[Q] Spica doesn't turn on

I had Cyanogenmod 6.1.1alpha8.1 on my spica. Recently it got a little bit laggy so i decided to flash it with odin to restore the original firmware and install everything else from the beginning. I tried to flash it with I5700XXJH6. The flashing went fine, but when spica started booting, only the first, static bootlogo showed up and there was even no progress bar. After 20 minutes nothing had happened so i tried to flash it with 1.5, then install Lk10 to get into recovery mode, so i could get access to the phone's shell. Unfortunately, after flashing everything was the same - static bootlogo and no progress bar. Installing LK10 went fine, but the phone still wouldn't boot into recovery mode. I tried many different ROMs and one of them worked - the system booted properly, everything seemed to work at first glance, but when i inserted the SIM card and input the PIN code, the phone got stuck on "Unlocking SIM card". I tried rebooting many times but it didn't work.
Once again i tried to flash it with odin and everything was the same as before. I tried a few times, but now there's no download mode and when i connect the phone to the charger, nothing shows up on the screen.
Is there anything else i can try to do?
i had and solved the same issue yesterday.
I think part of the issue is maybe with a previous FileSystem conversion and another part with data/cache from previous Roms.
Try to make an install as clean as possible.
- I5700XXJH6 with Odin
- LK2.08 with odin
now you have an acessable recovery.
- boot the phone and put the CyanogenMod 6.1.1 alpha8.1 (found on 'forum dot samdroid dot net') on the root of the sdcard.
- shutdown the phone.
Important: disconnect the phone before booting in recovery, else it will boot normaly.
- boot in recovery (Volume down, accept call, on/off button)
- apply the downloaded zip.
reboot normaly, if it loads normaly, yay!
If it doesnt load (wait 5 mins to be sure) pull out battery.
reboot in recovery, and wipe data/cache (factory reset)
reboot normaly, if it loads normaly, yay!
If it doesnt load (wait 5 mins to be sure) pull out battery.
reboot in recovery, and make sure data,cache and system are rfs.
to change it to rfs 'advanced>filesystem conversion'
reboot normaly, if it loads normaly, yay!
if not send me a PM.
I already tried installing I5700XXJH6 and LK2.08 but neither the system nor the recovery mode would load - only the first, static bootlogo showed up. I can't try again because the download mode doesn't work any more and when i connect the charger, the screen remains black.
As I wrote in the first post, i managed to get it working once, but it had problems with the SIM card, so i tried different ROMs, which seems to have broken my spica entirely.
Is there anything i can do to restore the download mode?
im assuming you tried starting downloadmode without it being connected to a pc.
I dont know how to restore downloadmode, perhaps the guys at the samdroid forum can help you out.

Phone won't boot! Please HELP!

This problem started when I moved back to Arya from a 5.1.1 port few days ago. I didn't bother much, cause I keep my phone on always, but whenever I wanted to go to Recovery or reboot the phone it would not boot, would stuck at the Note 3 N9005 logo and I had to do a battery pull to solve the problem, so yesterday I thought about flashing a stock ROM via Odin, and now the phone won't boot at all regardless of the battery pull method!
I can't enter recovery either, it stays at the Entering recovery (SELinux status screen) for a few seconds and then just a black screen with nothing at all. I did flash the TWRP tar image via Odin after flashing stock ROM yesterday, so that I can do a complete wipe, but nah, can't enter TWRP. Download mode however works after a battery pull.
Here is a video, probably the worst quality video you have seen lately, but it still does show the problem :laugh: So kindly tell me what to do! I have a non working phone for over 12 hours now, and I am realising how much I depend on a phone now, that feeling is inexpressible.
how did you solve it ?

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:

s7 edge reboots in logo need help please

Hello guys i have a strange problem. i am using my s7edge for over a year (finally was in batman rom).
After updating to marshmallow i encountered this problem where sometimes rarely my phone reboots (reboot- - show samy logo - then reboot). sometimes after few reboots it will comeback and some other time. i need to wait till it discharges fully and charge it it comes back. (but its so random though. totally happened 3 - 4 times last year)
from last week it happened quite often once a day and from yesterday it keeps rebooting in logo no matter what i do. when this happens only download mode is accessible and twrp recovery is not accessable at all. so i waited till it discharges fully but that does not help.since download mode is accessible i used Odin and flashed stock firmware, still the same result(tried several times). its just keeps rebooting in logo even after flashing with stock firmware via Odin and i have no more options to go for. is my device hard bricked? any more options i can try??? my final hope is someone here will help me.:crying::crying:
Thank you
Oh! I just posted a similar question. After several tries, I sorted out a way to make it boot:
1) With the latest samsung drivers on my notebook, I've downloaded the latest Odin (Odin3_v3.12.3) with this stock rom from sammobile (G935FXXU1DQJ4_G935FUUB1DQJ4_ARO). According to this page this rom works in Argentina and the ARO means it is used on unlocked devices. Then it has no bloatware or any company logo.
2)Charged it for a few minutes until it reached 2~3%. Vol Down + Home + Power (in that order) and entered 'Download mode'. Then plugged it into the pc.
3) Opened AP, BL, CSC and CP files, then flashed it. Once it restarts, try to get it into recovery mode with volup+home+power and charge it. I used a power bank. Then wipe cache and factory reset. Then reboot to system and let it loop until it gets into the OS.
The one I've got in quarantine is working smooth.

Need help to unbrick my phone

Hi,
I have a Note 4 t-mobile that is "brick" right now. and I hope if anyone offer assistance.
It is running Android 6. Ever since the last upgrade the phone would freeze and reboot on its own. I fixed that problem by installing Wake Lock. After that it would still experience sluggish at time but the phone is still very much usable.
Lately, after watching a bit of streaming video the phone would slow down so much that a reboot is needed. But yesterday my last reboot turned my phone into a brick. After that reboot the phone rebooted itself to the download mode. So I took the battery out, waited for a few minutes and put the battery back in and started the phone. Instead of booting normally the phone displayed the message including "set warranty bit: recovery" and then followed by the flashing TWRP splash screen. By "flashing TWRP splash screen" I mean the TWRP splash screen ( with the TEAMWIN logo) would be shown on the screen for a second, then the screen black out for a couple of seconds, then the splash screen is back on for a second, and the screen black out for a couple of seconds, etc, and never successfully boot into TWRP recovery. I had left the flashing splash screen overnight and nothing changed. Connect the phone to my pc via usb and fastboot wouldn't recognize my phone when phone was flashing the TWRP splash screen. So I tried to flash TWRP again by starting my phone in download mode "volume down + power". When I connected my phone to my pc Odin recognized my phone. But when I tried to flash a custom recovery (TWRP or CWM) it seems the download started but never finished (on the phone I could see the progress bar started but never progress further).
Any suggestions would be greatly appreciated1
Additonal info
I just wanted to add that my phone is still running the stock ROM.
Problem solved
Problem solved. Once I used a different cable and the download process actually worked and I was able to flash stock ROM using Odin.
