My note 2 doesn't bootup

I was updating to latest version of cyanogenmod through OTA and after that my phones battery just died I mean it showed 1 percent and even though I charged it, it still was running off the battery and no matter how long I charged it it just didn't boot up
I can load download mode\ recovery but I installed through odin a stock rom and still it boots up and says I have no battery and turns off even if it connected to the original samsung charger, and I can't just turn it on like with the power button I need to load recovery and then reboot.
please help me i'm really frustrated

Do you think that a battery can die just like that with no reason?
I think its a software problem and not a technical one.
does anyone have another solution?

You have good reasons to believe it's a software thing, yet you also don't.
Focus on what you are able to do at the moment.
Since your phone is just a brick now, no matter what your suspicions are, you need to test it with another battery and eliminate possibilities.
Either the rom you flashed bricked your phone, or the battery just decided to call it a life. Either way, you need a battery to test whether it did actually die, or to determine whether it's a true software issue.

Yup it could happen(at least to me). My battery can last 10hours then suddenly when I woke up in a morning my phone dead. Use charger while power on only last to samsung screen. Thought it's a softbrick so tried to reflash but not working. Luckily I have a friend with the same phone so borrow his battery

so I checked with my friends battery and it still seem to have the same problem.
so does anyone have another solution maybe?

Have you tried to clear Data/Cache? AFAIK Odin does not clear them. You can try to reset all partitions with Odin using PIT file and then without rebooting flash stock rom. Hope that helps.

Phone died from nothing. Please help

Guys I need help. My phone just died from nothing and doesen't turns on anymore! I was doing nothing but reading a Facebook post and then the screen shaked and turned off. After that I can't make it turn on!!! The charging battery doesn't appear when I connect it to the charger, but it turns on and shows a yellow triangle if I coonect it without the battery.
I am using stock V20h. What can it be? What do I do? I can't stay without my phone

Try another battery, from a friend or something... the fact that it turned off suddenly can be a battery problem.
I hope it's just a battery, good luck

Did you tried do remove the battery and put it back ?

Try to put the phone in fastboot mode and flash the stock file with lg tool and report back.
Also try to go into recovery mode if u have a custom recovery and do a full backup and then full wipe (system, data and cache)

My friend, just take it into a service center and get them to look at it
Sounds like your motherboard died on its own and most G3's are still under warranty

Thanks for the reply, guys. I've tryed all of that. Even got another battery with a friend of mine and got the same results. I'm thinking it's the motherboard too =/. Gonna take it to the LG service tomorrow. Do the fact of flashing V20h breaks my warranty?

As long it isn't rooted, your phone is under warranty as long as you have LG's original software installed. So, YES, you still have warranty

[Q] flashed tmo on att d850 HELP!

I just flashed a rom on my d850 and now the screen wont turn on the phone is completely unresponsive I don't know what to do I can't even get the phone to boot some one help me im sure I just bricked the phone..

First, what rom did you flash and how did you flash it?
Try this as well:
Pull the battery, press the power button for a few seconds. Put the battery back in and press the power button again. Pop the battery out a 2nd time and then put it back in. See if it turns on.
If that doesn't work, pull the battery and hook the phone up (without the battery) to a computer and again see if it turns on and shows up in device manager.
Flashing the wrong rom should only result in a non-booting situation. If you have a custom recovery installed, you should be able to still get into that. The d850 has some serious issues with successfully rebooting in general (which can be resolved by the two suggested procedures above), so I would suspect that before worrying about a brick.
Lastly, the d850 requires bumped ROMs to get by the locked bootloader. The d851 (T-Mobile version) does not have a locked bootloader, so the roms are not bumped and will of course fail to boot.
Once you get back into recovery, just wipe all partitions except for internal storage/sd card and install a correct rom.

When you say you got the phone on, what do you mean?
If it is on and showing up as a phone in Windows, why not just use the LG recovery tool and flash back to stock, then start over?

Give the lg firmware flash and recovery tools a go then. There are several threads on here dealing with unbricking phones that detail what you need to do.

Question about tmobile G95TUVU3DOI1

Hi, I'm kinda new to rooting android phone.I just got a galaxy s6 edge from tmobile and I would lIke to root the phone. Searching around the forum but still doesn't ubderstand how's it work. So I got a galaxy s6 edge, baseband version G95TUVU3DOI1, come with 5.1.1 SMG 925T. Question is if I'm root the phone will i able to restore back to stock firmware, will tmobile able to find out if I rooted or not? Because I'm in Jump! Program and plan to switch new phone next year. And its there any easy step by step guide to root the phone. I don't really care about Samsung pay, would like to have fingerprint sensor if possible. Thank you

Before you do anything, understand that you WILL TRIP KNOX AND BREAK SAMSUNG PAY. Also, it is your choice to modify your device and this process seems to work differently for differnt people, so if anything happens, it's on you. However, there are several threads here that can help you if anything goes wrong
Okay, make a backup of all your stuff on SmartSwitch
You're going to want to download ODIN 3.10.7 from here: http://forum.xda-developers.com/showthread.php?t=2711451
Then you're going to want to download UniKernel v8 from here: http://forum.xda-developers.com/gal...d-development/kernel-stockmod-kernel-t3100395
Open ODIN on your computer and don't touch anything yet
Then you're going to put your phone into download mode by turning it off, then holding POWER+VOL DOWN+HOME until a blue screen appears.
Press VOL UP to enter download mode and connect your phone to your computer with the cable that came with your phone
Wait for the little box at the top left to turn blue
On ODIN, click the AP button and locate the UniKernel v8 file that you downloaded before
Once you've found it, double click it to fill in the AP field with the file
Click START and do not touch anything until it's done.
Your phone will restart and once it comes back up, you'll be rooted. It can take several minutes for it to fully boot, so give it time.
Now, this is optional, but if you want a custom recovery to flash custom ROMS, download TWRP onto your computer from here: http://forum.xda-developers.com/tmo...recovery-twrp2-8-6-0-g925t-5-1-1-of6-t3143002
Flash that file through ODIN using the same process as you used to flash UniKernel.
This recovery will let flash custom ROMs. I recommend XstreStoLite as it is very good on battery life, but you will not be able to use WiFi calling or VOLTE. You can download it here: http://forum.xda-developers.com/gal...xtrestolite-deodexed-mod-edition-1-3-t3119968
Let me know how it goes.

Yes. There is a small chance, but the method I described is the exact same method I used on my device and I've had no issues. Even if you do, there is almost a 0% chance of a hard brick unless you touch something you're not supposed to touch, and if you do soft brick, there are a few threads here that should be able to help. More than likely flashing stock firmware will fix any problems you have.

thanks akw for the run through, I've been away from android for 4 months and ran back to it. just got this phone and wanna quickly root it.

Where are you getting the firmware from? What version of ODIN are you using? What port are you using in ODIN to flash the firmware?
There is a Mega download of the DOI1 firmware somewhere around here. I recommend downloading that and flashing using the AP port in ODIN 3.10.7, using the cable that came with your phone. This is the exact method I used to return to stock with no issues.

Restart every 2 minutes

I have the following problem:
My Galaxy S9 (G960F) has restarts every 2 minutes since a week.
The Samsung customer service thinks it is the circuit board, but he can only say more precisely when he has the device open - cost approx. 250 Euros. Is a lot of money for a 2 1/2 year old cell phone.
Maybe someone has an idea?
I am currently using an old iPhone but the move with Whatsapp does not work at all.
Greetings and Merry Christmas

flash most current FW with Odin and if it still does it, its probably a hardware issue and you might consider trading it in or something along those lines

I find it odd if it always shuts down at the same time every time.
Make sure battery is at least 60% charged and does indicate it's taking a charge ie battery %. Use know good cable/charger.
Try safe mode.
If you go to the boot menu and wait, does it cut it?
If not check to see if all hardware is working with the onboard diagnostic tests.
See what's set to have Administrator privileges; disable all.
Try a hard boot, and also clear system cache.
If that fails try a reload... run it before you load apps.
Try a reflash if all that fails.

Use Odin to reflash firmware. You can get the correct firmware on Sammobile.
I'd say it's almost certainly a software not hardware issue, if it started immediately after updating to Android 10.
Try rebooting into recovery mode and clearing cache and delvic first. Could be a rogue piece of software.

If the battery is low and not charging properly it will behave like this.
They auto shutdown when battery drops below 6% or so.
When you hook charger to phone without booting it up, after 30 minutes what's the indicated charge?
Then after shutdown, again without booting it up, what's the charge shown on the charge screen?

You do not need root to access recovery - The whole point in Recovery is to help out if something goes wrong. Reboot to recovery and clear the cache and dalvic. Then restart and see if the problem persist.
If problem does persist - Boot to download mode and leave the phone in download mode for a few minutes, see if the problem happens there. Because Blackhawk brings up a good point, you may have trouble even flashing the firmware if the device powers off in download mode.

Great. In that case, if I were you I'd try flashing the firmware. It shouldn't take more than 10 mins to flash. Ensure battery is charged to 100% to give best possible performance.
I mean, when the alternative is returning to Samsung and a €250 bill, I'd say it's worth a try.

If it doesn't work, then it means it isn't software and is hardware.
But considering Download Mode works fine, I'd say that pretty much cements the fact that it's software. Something was probably corrupted during the update. Since you've already cleared the cache ( You did that in Recovery, right?) then the best option will just be a clean flash of the update. You'll lose all data on the device, but you'll save yourself a bill from having to send it to Samsung.
As BlackHawk has said - A factory reset could potentially help. Might be worth a try before flashing stock.
