[Q] G3 bricked (i guess) Please Help me out ppl

I downloaded the kies version of the firmware of the froyo update and updated the firmware using odin.
After i installed froyo, i wanted to root to apply swype patch and everthing went ok but when i restarted, the phone was stuck on the i5801 loading screen for about an hour
so i flashed the firmware again.
Odin saves the data onto phone and restarts the phone and the phone opens recovery mode but now it gets stuck on a screen saying "delete app data"... "delete files please wait" and it has been stuck there for about 3 hours now and even when i try and open recovery mode, it opens but then this screen comes up
i tried flashing multiple times but nothing works, cant even factory reset now
Please help me out..
note:odin for a change shows a disabled reset time box.. it is faded out)
add http and enter "dl.dropbox.com/u/26157339/compressed.jpg"
here is a screenshot of the screen at which my phone has been stuck for about 3 hours
Also suggest if i should go to the service center coz the phone is under warranty, i really doubt theyd do it for free considering its rooted but i dont mind paying up.
And let me know if there is anyway the service center ppl will know i rooted/flashed

Try taking out the battery and then putting it back, and press the 2 volume buttons+home+power until the phone boots up in recovery mode... Try wipping the memory from there

that is the entire problem, as soon as it goes into recovery mode it starts off like shown in the screenshot
therefore it is not displaying the menu (which has options to factory reset/clear cache) instead its jumping directly to the update sequence but then getting stuck at deleting apps

Try flashing a different firmware, such as an eclair rom. Note that your phone is 5801, so look for those firmwares.

k ill try flashing an eclair rom. I did flash firmware specific to my version it self..
But the problem is that even after the flashing is done, the recovery window has to open where the update begins and thats when the "deleting apps" screen kicks in and doesnt progress
never the less ill try flashing another rom/firmware and see

Hmm, that is weird. Did you flash the bootloader?

tried flsahing a eclair firmware but no luck..
odin runs for a couple of mins, and says pass but still the phone is stuck on the delecting apps screen..'
For some odd reason, my recovery mode is hell bent on deleting some apps but is not able to and is getting stuck and therefore i cant reset/ clear cache..
Do u ppl think this could be coz of the root??
Please suggest something, i dont want to know my phone is bricked for ever considering its not even been a year since i bought it

a second flashing of eclair did it thanks man!!!

it usually works if you flash the very first rom that worked the last time you got problems.
did you flash with your sdcard in your phone?
anyways im just glad you fixed it

[q] stuck in bootloop sprint ls980 please help!!!!

OK to start off i am not a noob at this, i have read though the forms and cant seem to find out why my phone will not come out of this bootloop. This started happening 2 days ago when I went to install a new rom on my phone. I powered down my phone, put it in recovery (Twrp), I wiped everything but internal storage. I then processed to flash the new rom. Everything went great. My phone rebooted and worked fine for the first 1 min, when i tried to pull down the notification bar the phone stuck off and went into a bootloop. I then tried to go back to my old rom and had the same problem (notification bar would not pull down). So i went to plan B and used the Back To Stock Form to restore the phone back to stock. The process went smooth as well not a problem at all. When the phone started up it allowed me to set up the voice navigation and name of the phone, as i went to update the prl and profile the phone shut off again, when it turned back on it starts normally and the goes to the lock screen where i am unable to make any iterations with the screen at all besides when it turns the blacklight off, as i try to use the knock on the LED light turns white but the screen will not turn back on (not even with the power button). Then it reboots to the lockscreen again and continues to do it until i manually force it off. I have tried everything from redownloading the firmware files, tried back to stock 3 times, hard factory reset, and reset in recovery mode. My phone is back to stock but i am unable to do anything with it unless i factory reset and go though the set up again, but even then i cant get a connection (even with wifi) without the phone shutting off and rebooting. Everytime the phone reboots the time reads 12:00am and switches to 12:01 really quick. I cant get a connection at ALL (I EVEN TRIED REMOVING THE SIMS AND AND PUT IT BACK IN AFTER BACK TO STOCK PROCESS.)
Im not sure if the application Dr.Web could possibly be making my phone do this. I did have it installed and did not remove before I tried to switch to the new rom. The anti-theft part was active.
SOMEONE PLEASE BE MY HERO AND HELP........I REALLY WOULD HATE TO DEAL WITH LG ON THIS ISSUE IF I CAN FIX IT MYSELF

god that is really hard to read...did you make a back up before you do installation? if so do a restore, if you dint, download another rom, kernel, put it in your phone, wipe everything except internal storage via TWRP then flash rom then kernel.

I had the same problem except with me, i was just trying to change fonts manually. It went into a bootloop and i stressed dover it for hours until finally i found out that you have to use the lg mobile support tool (you can find it in one of these threads on the lg g2) and revert it back to stock. That fixed it perfectly fine. Its a lengthy process but simple. If that doesn't work you have to do what the lg mobile support tool does semi-manually with another program lg flash tool which is longer but just as simple if you follow the directions given in the thread to the letter.

**** thats not good at all. This happen when I was using my S3, if IMEI is gone then you could not use the phone at all, theres no way you can get it back unless you made a back up. you have to sent it in man, sorry this is as good as hard brick.

My friend also has a lg g2 that i rooted for him would i be able to use a backup from his phone. Also when i turn the phone conpletely off and hold down all 3 bottons it brings me to a hardware key settings it does shows my imei number there. If i sent it into lg would they know the phone was once rooted or does the back to stock method cover it up? Thanks for your help btw

they have coders there, I'm sure if they really want to know they can figure it out. If you send it in to get it fix out of your own pockets (meaning you pay them) then i'm sure they dont care, but if you want a replacement due to warranty then it may be a different story.

I eneded up restoreing my phone back to stock and took it into my local sprint store it cost ne 75 dollars to replace the phone not under warranty (if u have sprint protection its free) i told them i took and ota update and it started rebooting itself. If you do get a replacement make sure u back up your efs files to a safe place on your phone. Theses files can become corrupted by flashing roms and kernals.

Not under warranty? Doesn't it have a 1 year manufacturer warranty? The G2 wasn't released on Sprint until November last year so it should have been covered.
Sent from my LG-LS980 using Tapatalk

Yes its still under manufacturer warranty but when i made a repair order with lg it said it would take 2 to 3 weeks to get my phone back and if they found out it was due to being rooted and flashing roms im sure lg would of charged a arm a leg to repair it. With sprint i got a new phone in 2 days or ordering it.

Hardware or Software Issue? (Diagnostic Needed)

Hello,
I am having issues finding what the problem is on my phone. The problem all started when I rooted and installed a custom rom on my galaxsy s5. It worked perfectly for a couple of months. Then I started noticing this weird issue whenever I plugged in any headphones the phone would automatically restart. I didn't really look into the problem like that and just kept it the way it was, since I used bluetooth alot.
The problem progressed to the point that when it restarted itself it would go into a boot loop. I would have to take out the battery wait a few seconds then plug it back in. At this point I decided to restore back to stock firmware. But this made the problem worse. Now its a 15% chance the phone boots up normally, and 85% chance it boots to a black screen. By black screen I mean it boots up normally but I cannot see anything on the screen. I hear the sounds, and touch still works.
If I am lucky and it boots up normally it works perfectly for a few hours. Then at randomly when I put the phone to sleep it restarts itself. There is no reason I can think is causing this problem.
Phone Info:
Model: G900T 16GB
Firmware: Stock 5.0
Flashed With: Odin 10.x.x
Please help me diagnose my problem so I can fix it.
Possible Hardware Issue:
Digitilizer/LCD : Black screen explains this. But also if I do not put the phone to sleep it will work for days. Boot screen, Download Mode, Recovery all work without problem.
Internal Memory - Could be, that means I have to throw the phone away. But wouldn't nothing also work...
Click to expand...
Click to collapse
Possible Software Issue:
Corrupt Rom/Cache: Flashed several different kinds of stock rom, all with same result. Used recovery to delete cache.
Virus: Yeah leaning towards this.. Maybe somehow hooked itself to the core aspects of the phone.
Recovery/Download Mode Corrupt: This part of the phone is corrupt. 15% chance of booting to recovery. And Download Mode doesn't delete all user data.

This should be normal because MarshMallow was just released so its buggy for everyone ?

exact same problems that i'm having. the phone has become unusable. i have flashed 5.01 and its working again, but now...google didn't even load my old apps. so i have a totally fresh phone,,,which is a p-is take. at least its working. i'll try 5.1.1 when i download it.

i sat and messed about for a few hours and it working mostly ive managed to get the apps updated and seems alot more stable still get the odd lag and slow load on apps but it's not usable i think my main probelm was the apps once they updated "which they where stuck on" its seems to have sorted a few of the issue's

i have tried to reset the phone 3 times aswell as a fresh install of the firmware 3 times same responce each time my phone seems to be going through stages of working fine not working fine and being unresponsive seems to be the fingerprint scanner crashing alot and also just freezing just typing on the handset

To coatsy101 :
Give it to Samsung authorized service centre. If your phone is under warranty, they will not charge you. No problem if they charge you if your phone is out of warranty. Do not flash any firmware by yourself. It will brick your phone by deleting its IMEI. Beware of this !!!. So give it to the Samsung authorized service centre in your country. Search in google and find out.

phone is totally mashed. it still freezes and lags , then reboots. works ok for a bit then,,,same thing.
i've never had this happen before. always got fixed by flashing firmware. but this is new to me...tried so many different firmware now...i just cant understand it.
might root and try a custom rom next see if that helps. (

well the closet samsung place is about 3+ hour drive so i wont be doing that. kris 3 is all ive been using to reinstall the marshmellow update and the 3 factory resets ive done ive gave up with it basicaly at work and sit for 5 to 10 minutes waiting for it to unlock somethimes ive disabled thh fingerprint scanner which has helped slightly but still u unuseble my head is battard with it

i've done numerous factory resets and tried different firmwares. it is the same, works for a few minutes then suddenly will freeze and come back after 30 seconds or so...or do a reboot. i've re-partioned nand wipe factory wipe cache wipe .
don't know what else to do. will root and run a custom rom as a last resort before smashing it and throwing it in the bin

You have to use Odin 3.10 or 3.11
Turn On Developer Mode on your phone by going to Settings > About Device > Build Number > Tapping Build Number 7 times
Then go back to Settings, you'll see Developer Options now, click it and then check USB debugging
Switch off phone, then hold Volume Down, Home and Power at the same time, it'll ask if you wanna download OS, then press Volume Up
Unzip Marshmallow file, Run Odin on your PC, then connect phone, make sure it registers with Odin, it'll say "Added" means registered
Select the Unzipped Marshmallow file by checking AP and then pressing AP, don't touch anything else, wait for the selected file to be checked, the START at the bottom will be grayed out, but within seconds it will come back again, now press START
This will flash your phone with the selected Marshmallow file, wait until, ODIN says PASS with Green, now you can disconnect, phone will restart automatically.
DON'T PRESS ANY BUTTONS apart from AP and START when flashing

N910F problems - emmc read fail/ flashing stock no longer boots the phone.

Hello. I had gotten this Note 4 phone which had a custom recovery installed on it but the rom seemed to be official, on 5.1
The first thing I did was go to samfirmware and flash a 6.0.1 rom, it went fine, phone was working properly. Then I got greedy and wanted to test a Note 7 ported rom. Flashed TWRP recovery and from within I flashed RamROM http://forum.xda-developers.com/note-4/snapdragon-dev/rom-sm-n910g-ramrom-t3400349 , I downloaded the one from post#2 , the N910F one that my phone is and after it flashed to ROM it simply stopped working. My phone no longer booted, was booting me directly into Download mode with emmc read error. I kept trying to flash the stock rom which I previously flashed and it would fail.
Afterwords I used Smart Switch to reinitialize the phone, writing my phones S/N and that failed as well but at least that made my phone boot into a different recovery where it said to connect to Kies. Once again I used Smart Switch and this time it was successful 100%. My phone even booted into the OS and was working, however, while using it, after 10 minutes the phone restarted into Download mode with emmc read error.
So all in all the phone is functional but it starts to lag and restart. Now I'm kinda stuck again since I've tried to flash the firmware I got from Samfirmware through Odin, it succeded but it just doesn't boot, it goes to Recovery, tries to apply an update and I get an error.
Is there anything I can do? I can't believe the emmc could've broken just from trying to flash that custom rom, especially that afterwards I was even able to boot into the phone.
Thanks for reading and I appreciate the help.

My phone no longer booted, was booting me directly into Download mode with emmc read error. I kept trying to flash the stock rom which I previously flashed and it would fail.
Afterwords I used Smart Switch to reinitialize the phone, writing my phones S/N and that failed as well but at least that made my phone boot into a different recovery where it said to connect to Kies. Once again I used Smart Switch and this time it was successful 100%. My phone even booted into the OS and was working, however, while using it, after 10 minutes the phone restarted into Download mode with emmc read error.
So all in all the phone is functional but it starts to lag and restart. Now I'm kinda stuck again since I've tried to flash the firmware I got from Samfirmware through Odin, it succeded but it just doesn't boot, it goes to Recovery, tries to apply an update and I get an error.
Is there anything I can do? I can't believe the emmc could've broken just from trying to flash that custom rom, especially that afterwards I was even able to boot into the phone.
Thanks for reading and I appreciate the help.

read this - http://forum.xda-developers.com/note-4/help/note-4-issues-t3453048
there are links to more threads related to your issue.
Short version though:
it is dying. install wake lock application, add it to start up and set settings to #4.
accept the fact that your phone will eat the battery faster and one day WILL die completely

Thanks for your response. Regarding the Wake lock application, I'm starting to look into it, I asume I'll have to be rooted. I'll try to recover it again using Smart Switch and then I can only hope I can install TWRP and still have it functional.
Previously when I was able to get it working with Smart Switch, entering the recovery messed everything up. It said it was applying an update and that got stuck.

no need to be rooted, just download, install and set it to autostart

I'll try it if I somehow manage to get the phone working again, Smart Switch just fails now midway through.

Is this the app you're talking about? https://play.google.com/store/apps/details?id=eu.thedarken.wl&hl=en
What exactly does it do?
I managed to restore it eventually with Smart Switch, it took quite a few tries, then I switched to my Macbook when I saw the app was available on it too and the 3rd try succeded. I only did it because I saw the 2nd try had the % much higher than the first.

yes, that is the app.
i've read it does not allow your phone to go to sleep mode.
drains the battery faster, but this is the only way to keep note 4 working without swapping its motherboard...

I have a question, my gf recently bought a note 4 and we may swap our phones and if we do, i'll flash CM and tinker with it because i find this phone very interesting, just a question, does this bug affect the N910C (exynos) model? Do i have something to worry about? Because the phone is warrianty protected and if it's the case, i don't want to break it. I hope someone will shed some light on this
