[Q] epic 4g permanently bricked on 2.2???!!!

I had my epic 4g and Odined to Dk28 with gps fix, clockwork, etc.
I played paintball and some of the dust went inside but when i got home i wiped the keyboard and slider. slider seems fine
I had the GPS running for about 2 hours until I got home. There was about 1/3 or 1/2 juice left but then It shut down and restarting, stating it only had no power left.
I took out the battery and it still boot loops (it gets to home screen - loads sd card/usb debugging/wifi and gps are on, but then reboots. im not even able to turn it off.
I tried pressing 1 and power for odin, it worked once or twice, but i wasnt able to flash it and restore it. (Yellow Com) but failed or not work.
after that 1 and power doesnt do anything, and neither does power, vol down, and camera.
please help, as i need to go back to work tomorrow.
thanks in advance.

Boot into Download Mode, flash back to stock (check the Epic Wiki for instructions), start over. Sounds like you've just got a bug somewhere in the whole process. Unless you've deleted, moved or whatever'd something you shouldn't have, you shouldn't be having this issue.
There is a thread for fixing bricked Epics.

If you press pwr, 1+pwr, vol. down+camera+pwr and nothing comes on nor charge light (red) comes on when plug in, then you have a very shiny expensive paper weight.
Sorry bro. I have one sitting on my desk with no insurance (OUCH)...

no light when i plug into usb or charger. cannot get into download mode. Wow i could brick a phone in under 3 weeks of getting it. going to sprint store.

Let us know what they say, Last time i went into the sprint store for an exchange they intentionally split water on the water damage film to try to say I voided my warranty. the reality is that they had already done diagnostics on the phone before they did this little trick so i was able to threaten to call my lawyer and got a replacement. I hate sprint so much....

Ouch, how did you know they already ran a diagnoses on it?

fone magically unbricked itself so i was able to get into download mode an Odin a 2.2 again. but the battery seems iffy...and this is only 3 week using the phone. its at 9% charged but shuts off. need to see if i can fully charge it. but may end up getting new phone at sprint store since its under 30 days and fone still looks new.

Maybe you just got a bad battery

Sounds like you need to reset your battery stats.

didnt get new phone yet since phone hasnt bricked itself again yet.
i fully charged it last night and took it off teh charger before i went to sleep. now 10 hours later. its at 66% is that NORMAL?
sprint cust support said i should use default CHARGER to get best charging results. im using a ebay generic CABLE on USB does that matter? do they mean charger or cable or both?

A plain USB cable used to charge on a PC only draws 380mA to charge. A wall charger, like the one included with the phone, will charge at 600mA.
But still, neither should take the 10 hours you are seeing really. Wall charger is usually 3-3.5 hrs and USB charging is somewhere around 5-6.

66% after 10hrs of use seems normal to me.

sry double post. using tether internet...

UH OH!
I was installing from some apks and the phone got into boot loop AGAIN!
I'm thinking about going to sprint and exchanging it. But im afraid of rooting it again...bc i think it might trigger the boot loop again. Any ideas?
re: last post, 66% after 10 hours of idle with screen off (this is "use"?) is normal?

[Q] Possible fix for my Nexus 4?

Here is my problem. I have a Nexus 4 that constantly powers off. And by power off, I mean as soon as the Nexus 4 boots up into the OS, the phone starts the power off sequence.
What I've tried so far was:
- in recovery did a factory reset, wiped both the data and cache partition.
- tried reloading the official nexus 4 firmware. Tried the 4.4.4 and 4.4.3 image
- used fastboot to load up a custom recover only to realize there is no rom on the phone itself to install from so that's out of the question pretty much.
- I tried the adb sideload but the computer doesn't see the nexus 4. the computer however sees the phone when it boots into the OS but the phone starts the shutdown operation as soon as it loads the start screen.
If it's hardware issue, then I guess there's no point in trying to fix it. But if it's only software related I want to at least try to see if it can be saved. lol
Any suggestions?

Well I know this happens when you have 0% battery
maybe your battery isn't charging?

Try booting with your N4 plugged and leave it plugged so 5 minutes, check your battery status and if it's ok unplug it and cross your fingers.

I thought about that at first. but according to twrp the battery life was above 70% and can run on battery perfectly fine. The phone doesn't actually belong to me. She gave up trying to fix her problem and got a new phone. I just got curious and want to find out what is causing the issue.

I left the battery charging all of last night just to try it regardless of what the status said. It was hovering at around 70-80% according to TWRP before I plugged it in. It actually made progress today. The phone booted up. So I put in LPV just for the fun of it. The first time it booted up into LPV, it was doing the shut down process as well. Plugged it back into the wall for 5 mins, unplugged it and turned on like normal. Went through the set up process.
Left it sitting there for about an hour. Then decided to shut down the phone and restart it to see if that issue would return. Didn't return until Play Store started doing updates. The phone shut down. Powered it back up and it was fine. lol. Battery life right now is sitting at 78% and battery widget reborn is saying the temperature is 39C. So it coule very well be the battery. But my friend said the guy she brought the phone for repairs supposedly changed the battery. lol. So I don't know.

Yeah, sounds like a possible bad repair. Try another thing, flash a kernel not based on stock, like hell's doctor or hell's core. After 4.4.4 there are several issues like boot loops and shutdowns with kernels based on stock.

Well it's running Android L Preview port so it's not running 4.4.4 based rom. At least to my knowledge. I'm going to see how long this last. I suspect they didn't really replace the battery or it could be an issue on the motherboard side not detecting the proper charge level on the battery? But battery life so far on the phone seems pretty crappy. 13% in the last 45 minutes on airplane mode with wifi on.

Note 4 annoying battery issues!

I ordered a Samsung Galaxy Note 4 (SM-N910T) last week on Ebay. It is a refurbished one sold by a seller named Cellfeee. On the first day it came with 0 percent. So I charged it with the generic non-fast charging charger it came with and it worked good until it suddenly turned off on 5 percent and I couldn't turn it on until I put the charger on. The next day I used another charger with a fast charger (not sure if the charger was broken) and it took 7 hours all night to charge but it strangely last for 10 hours and shut off at 20 percent. Is this a common issue? Should I send it back or order a replacement battery?

I have the same issue my phone n910t shutdowns at 20% and sometimes at 15% and phone won't turn on.but i can enter download mode and it remains on for hours
but when i plug in fast charger back it shows same 15% then why the hell it won't turn on ?
I think its nothing wrong with my phone not refurbished never rooted it definitely could be bad battery..

I have the same problem with my 2 year old Note 4 - bought a new battery but that didn't fix it. Phone usually shuts off at around 15-20% battery. However, when I connect the charger it shows 0%.
So, either there's another hardware fault which is misreading the battery level, or there's a problem with latest Android or Samsung app which is causing it.

Try this
Dial*#0228# and press quick start at bottom of the screen and hit yes.
This will clear old battery calibration status.
Then turn off the phone and charge to 100% and reboot
And your new calibration status will create automatically.
I did this and now my phone is not shutting down at 15 or 20%.

Hey trex.. i have the same problem phone shuts down at 15 to 10% but when it shuts down it goes to bootloop whenever you power on the phone it goes again to bootloop but once you connect the phone to the charger it boots just fine! I'm on stock rom not rooted, 8 month old phone. Did you noticed this behavior n your phone or it's just me .

I tried that with 2 batteries. I have bought a now oem one and it's worse than the 2 years old one.
I have exactly the same problem as everyone else, the phone shuts down at 20-30-40% and sometimes even at 50%.
Edit: I was talking about the *#0228# method.

I never face any bootloop issue. after i recalibrate bettery status its perfectly fine.but still sometimes when phone heats up a lot while gaming and it shutdown at 5 or 8%.
Maybe you flash a clean stock firmware and make factory reset after flash should fix this bootloop issue.

Thanks for your reply, it isn't bootloop as i described but it fails to boot if the phone is not charged enough( it should be over 5 percent) it will go to Samsung logo the restarts again unless i connect the phone to the charger.. very strange behavior! This started to happen after November security update.. i was thinking to factory reset but i have too many apps and without TB i will suffer backing up all these data 😣.. if factory reset did not help i will send it back to Samsung service center and let them suffer 😈.. thanks for your help trex really appreciated.. cheers

It might be a software issue. The battery still lasts pretty long even though 20% is like 0%. So buying a new battery didn't help. Did you try a non-oem battery? if so, did it do the same?

It might be because your battery can't supply enough power. I had the same problem and brought it to Samsung, they said I only need to change the battery. And since I had another backup one, it was fine and decided to buy 2 more batteries just in case. No more problem so far.

Battery stuck at 50%

Hi everyone, my Xiaomi Mi A1 black is stuck on 50% battery since yesterday. The phone charges, but it still got stuck.
I have tried a wipe from recovery, but it didn't helped. I let the phone discharge completely and shut down by itself and then to plug in, but when it started charching it still shows the 50% indicator.
Any idea? Thanks in advance.

Noone?

Seems too strange.
Try to let discharge until it dies, the restart the phone by pressing vol up + power btn (recovery mode) and wait until it dies again.
Then, you can connect it to the charger and wait 2-3 hours. It must be kept powered off.

Thanks, I tried to let it discharge and charged again for 3 hours, but I didn't make the recovery first. Actually, when it dies, it doesn't turn on again...I will try anyway with your method.

i would suggest you to get a replacement or a refund. this looks like a battery issue to me which is obviously hardware. so it's better you yet it repaired /replaced or get your money back. as far as i know i haven't heard anyone having this issue.

Same issue.
Hey legends, I have this same issue with my miA1 black. It's only about a month old and the battery works fine. Just the Meter is stuck on 50% and I have no battery data available in the settings menu. Any ideas?

This issue happened to me two days ago, to fix it you just have to unplug and plug the battery connector from the motherboard.

Fixed!
All sorted, thanks for the help ?
p.s. most difficult device I've ever opened! It was really stiff but the battery connection was easy!

thanks
Thanks for your help problem fixed for me.

I just replaced my lcd on redmi 7 onclite and that issue happened to me.
To fix this bug
First turn of the phone then unplug battery connector for about 5 sec and reconnect it again

An other (un)usual problem with dead s7 edge

Hi all,
So I'll start with backstory.
Is an 2 y/o S7 sm-g935f of my friends mother (which looks as new, not even 1 scratch), with initial problem that phone froze.
So first remedy was to reset it (vol - + pwr btn) but phone was unresponsive (which is weird), so she left it for a day to drain the battery afterwards plug into charger and working fine. At least for few days, then problem come back, and in matter of days started to freeze every time after 3 minutes of boot.
So I got it to me, and updated to latest fw from March/April 2019 (ending emc1 or smthing wise-like). 1st Flash successful, but froze on erasing/applying updates 25%, but reset it and it went trough, got AccuBattery app which was saying 84% battery life left, which isn't greatest but not bad. So after that I deleted all accounts on phone (used mine GA for playsotre) and flashed it again to have a clean start, after flash I watched it trough the process and it went flawlessly till "hello screen" at this point I turned off phone normally so she can set it up on her own. And from then (1 week later) phone won't turn no or charge at all, now I took back glass off (is not my first time doing it) and got 4.1V on battery which is a bit low to power it up, but it won't charge (before was charging normally), tried to unplug the battery to see if its in loop, but is just dead... Next step of mine will be to take battery out and charge it before replacing it (don't like wasting my/others money). If anybody got similar experience, I would like to hear from you.

Never had an issue with battery and my phone is 3 years old

So I took battery out, used my battery charger board to fully charge it, but it seem the battery doesn't work properly, so got ordered cheap knock off battery from ebay just for tests and waiting...

Sorted out, it was the PMIC (u7000) that failed. After researching a bit seems to be very common issue on this device. (Like iPhone signature failures). Sorted out by swapping motherboard (£35, is more money effective for friend/customer than £10 for ic + labour of 1-2 hours of micro-soldering).
