[Q] Cannot turn off my phone without it Hard Bricking

I am currently having trouble with my phone, it works fine as long as i do not turn my phone off. If I turn my phone off it seems to go into a hard brick, and I cannot get back into my phone unless I use a homemade jig to get into download mode and there for getting back to my phone rebooting. I noticed this problem right after I downloaded the teamwin app to update my recovery, but I accidentally choose the "I9300" recovery instead of my phone "I747". That initially put my phone into the first hard brick that I encountered, then with the help with www youtube com/watch?v=y5_yoJilLe0, I was able to get my phone and flash the correct recovery as well as a new rom. So my question is, how can I fix this problem of not turning off my phone and making it go into a hard brick? Any help will be much appreciated, and I am sorry if this is in the wrong place, this is my first post.
I do have a nandroid backup that I have tried and it still has this problem
Further testing I have figured out that I have to have my SD card that has the software to unbrick(using the method in the youtube video) in my phone for it to turn on. With my SD card out it acts just like a hard brick.

Sounds like a bootloader problem...

You probably flashed over sbl1. Its not included in firmware updates so the odin flash will not help.
Thats just a guess though. It depends on what partition the i9300 stores its recovery. It may be a different one from sbl1.

Ok, I just checked and you wrote over the rpm partition (mmcblk0p6). This is included in the firmware package so flashing with odin should have fixed it. Did you not flash the firmware? You said you followed a video, but you should use the instructions we have in this forum.
It also helps to know what build your current firmware is.

[Q] Stuck on Samsung Logo

I need some help with this issue. I was upgrading my phone through kies going from 2.3.5 to 4.1.2 stock, when something happened and the install failed. When the phone boots up, it remains stuck on the Samsung logo, as I figured would happen. I am temporarily using this phone until the end of the year when I get a new phone. My old phone was the GS4G, and I have cyanogenmod 11 installed on it, so I am reletively familiar with installing custom roms, just not interested in doing it on this phone yet.
So.... anyways, I tried to get into download mode, with complete and total success. BUT.... ODIN will NOT recognize the phone. ODIN recognizes my wifes S4 and my old GS4G, no problem. I am able to get into recovery mode as well. And as you guessed it, another BUT....... it will not recognize the SD card so I can't install the zip file from there. The phone had no problems with reading the SD card until I attempted to update the phone, so I know its not the drive slot.
I am at a loss. The recovery mode only shows the files on the internal memory, so if theres a magical way to transfer from the SD card to the internal memory with download mode and recovery mode as being the only options, let me know. I have tried 3 different computers, 15 different installations of the USB drivers, and 6 different SD cards, so I know its not any of those. Also tried 3 different usb cables.
Please advise as I am at a total loss as to what to do. I always knew from my GS4G that if you could get into download mode, you were good. And even if you couldn't get odin to work on it, there were various java scripts that would find ways to work. I have not found any for this phone as of yet, but maybe I missed something.
Thanks for anyone that can help!!

Start with the simple stuff.
Odin won't work if kies is running at all. In fact, easiest thing to do is uninstall Kies . If you MUST have it... later reinstall it.
So get rid of Kies. Then try different Odin versions. 3.04 and 3.07.

Another thing is to somehow try another PC.

Thanks for the reply. I will give it a shot and see what happens. I will post results hpefully tomorrow. Just got done with work at the fire house and now lots of housework to do.

[Q] Phone won't turn on after unrooting to factory

I followed directions found online to unroot and restore the SIII to factory. Everything went fine I followed all the directions: downloaded the Stock ROM onto the phone along with Mobile Odin, Mobile Odin Flash Kernel and Triangle Away. Ran Triangle Away successfully then loaded the Stock Rom with Mobile Odin and even Flashed the Kernel without a hitch! Phone rebooted and I was presented with messages about the phone having to reboot to install updates, etc... I let it - the phone reboots and now ceases to turn on. Nothing works! I've tried pulling the battery, holding down the power button with and without the a battery, tried turning the device on while plugged in to wall - nothing!
I'm thinking maybe the main board got fried? If that's the case is all lost with this phone? I really do like this phone and would hate to lose it to such a dumb mistake especially when I was just trying to restore it to it's original state.
Any way to save this phone? Anyone else have had a similar problem and solution?
Thanks!

Never stock flash a Full Official ROM with mobile Odin, youre bootloader got corrupted and you'll need a 16gb class 10 sdcard to repair it, search this forum for the debrick image.
Official Stock can only be done PC Odin and Kies.

Or 32gb if you have that model

Help! March OTA borked my N7!

Hello,
I really need your help and expertise.
I got the notification that I needed to update my N7 with the latest OTA security updates. I let it do its thing and noticed after some time that it was stuck on the Google logo. I tried restarting but nothing would work. I read what I could about some people tapping the back of their units and then working again but that unfortunately didn't work for me. I tried to start in recovery mode but that didn't work and then the power plus vol up. It tried to finish installing the update. But I soon got an error message with the Android guy laying on its back with a red arrow on its stomach saying only "Error" nothing more or less. Not sure what to do next, I tried to find info on suggestions but after about 5 minutes, it seemed to try to reboot and went right back to getting stuck on the Google logo.
I've never had any issues with this. It's stock (no root) and had the Marshmallow update on it running just fine. It's completely unusable now and I have no idea what to do to try to fix this. Any suggestions would be really helpful. Thanks so much!

Please post the output of:
fastboot format cache​
but if the response is "FAILED (command write failed)" then let's discuss it in the thread linked in my signature.

use nrt, would solve your problem.

download the stock firmware latest and flash it either on fastboot or use nrt instead.

How to root LG G3 VS9854CA

Hi,
I know this is a typical newbie has no idea what he's doing scenario, so I apologize. However, I feel like I've tried everything and am yielding no results.
I am trying to root a Verizon LG G3. Since I'm not entirely sure as to the technical details, I want to explain what I think I know. To my understanding, there are different versions of VS985? I haven't seen anything resembling 49A, 49B, or 49C, but the closest thing I found was the software version which said VS9854CA.
The first thing I tried was the One Click Root tool. The tool did not find any methods of rooting though. The next thing I tried was TowelRoot. I set my phone to stay awake while charging, and pressed the "Make it rain" button. It turned yellow as a response, but did not do anything else even after leaving the phone untouched for eight hours. I also tried to ADB tools but "adb reboot fastboot" only rebooted the phone back into the OS, and "adb reboot recovery" showed an android figure with the words "No Command" for a small duration before rebooting back into the OS. The final guide I tried was the KDZ and TOT methods. KDZ resulted in the message "Upgrade stopped due to an error," and TOT displayed "READY!" for the COM41 but did not attempt anything even after unplugging and plugging the phone back in.
Can anyone help me please? Could there be something I'm doing wrong in any of those methods?
I appreciate all the help I get. Thank you.

I'm in the same boat. I just got this phone from eBay, thought it would be easy to root as I used to have one and that was my experience at that time. Things have changed... There is no root for this latest software version 4CA. Totally sucks!
Any suggestions for a comparable phone that can be rooted when on the latest stock update? I'm on Verizon btw...

just use the LGFlash Tool 2014 and flash the 47A KDZ (6.0) file and then rooted using KingRoot 4.9.6 .. Now going to flash twrp and them fulmics rom.
I have tried everything else nothing worked for me. I was on VS985.... MRA58K (6.0.1).. Tot method didn't worked...flashing 10b KDZ also didn't worked.. They keep giving error.
