Phone bricked, unbricking TUT not working.

I was updating my Dash the other day to Ookba's latest rom when I received an error message. It gave me instructions on how to fix it (loading it in bootloader etc.), and I received a message saying it was successful and the rom would continue updating. I received another error message saying the rom was corrupt, and the program shutdown. My phone will not power up now. It was at(or near) full charge while reflashing, but will not turn on regardless of the button combination I hold while attempting to power it on.
Any ideas? Thanks!

what rom did you attempt to load in the bootloader? it should have been the factory rom..if not, then that is probably the root of the problem....as far as it not powering on now...I leave that open to the forum...cuz' I have no relevant advice on that one....

when trying to do the gold card method to unbrick my phone, it say Invalid certificate ..? wats this and how to fix it.

I was trying the "[ROM][EXCA][WWE][* 3VOLUTION SERIES *][WM6.5 STD 21854][Build 3VO.3.00.112509]" when it locked up on me, and still hasn't been able to power up.
Today when plugging it in after a week of letting sit, a red led light showed where the normal orange/green led would normally light up when charging/charged. The light stayed on for a few seconds, then shut off. Nothing else though. Any other suggestions?

Red light my friend means your battery is gone, probably your phone is not bricked maybe it just needs a battery replacement

I am having the same issue, except that I can place the battery in another Dash and it boots up just fine, so I am assuming it is not the battery. I will buy another one to double check. My problem is the same as which is stated above. Can anyone help? Thank you.

Just an update to see if I can get anymore suggestions. Hadn't touched the phone since the last post. Bought a new battery for it this weekend and it's still dead as ever. Won't boot at all. Not into bootloader, nothing. I get absolutely no response holding power+cam or softkeys+power.
Any advice? I don't absolutely need the phone as I've picked up a G1, but it would be nice to have this working, or at least trash it if it's junk.
Thanks!

Everyone else stumped too?

Have you connected to the wall charger to see if you get some response with your new battery?.

Just unbricked mine after being dropped again by the girlfriend. Try this, plus usb cable into device, press the camera button only. See if that gets you into the bootloader screen. If so, flash the oem build and go from there.

Tried it plugged into a wall charger for 3-4 hours, car charger for another hour, and computer/usb for another hour. No response anytime.
I'll try the camera only method when I get home later.
Thanks!

Just tried plugging it into the computer and holding only the camera. Didn't work. Tried that, tried holding power+cam, power+soft keys etc.. What's weird is I had the battery cover off while doing this, and the battery slipped out while I was holding cam+pwr, it actually loaded into the multicolor(bootloader?) screen twice, but would shutoff within a few seconds. Now I'm back to no response from it.

Finally got it to stay on the boot screen without turning off, but can't get it to establish an activesync with the computer so I can't flash it. The computer is obviously detecting it though, because I see an icon that says "remove smartphone usb sync".

The phone's FINALLY working again! Thanks again guys! I was a couple of days away from junking the thing! I couldn't get Ookba's rom to flash it, so I went back to the unbricking tutorial and saw that he recommended grabbing the factory rom to flash it. I did, it worked, and I just flashed it again using Ookba's rom.
Took quite a few months, but it's back! Thanks!

xda universal dead

pls help me ..i lost connection ugrading to a new rom...now my xda exec universal is dea...even cant get into bootloeader..onmy soft reset and when i press the O for factory defoulds .still does nothing just goes to its dark screen

put it in to bootloader and flash a new rom.

universal dead
thanxs for the replay ..the universal dont even gets in bootloader. when i press the 3 keys for geting in the bootloader ,it does not .what else can i do???

Please read the wiki before posting:
http://wiki.xda-developers.com/index.php?pagename=Uni_Stuck_Bootloader
http://wiki.xda-developers.com/index.php?pagename=Uni_Stuck_Bootloader_Serial

I think what dekyprio is saying is that the Uni does nothing while powered on. I have the same issue on my side, so for now my Uni is waiting in a box for the process to bring it back to life :-(
Any help would be appreciate.
Regards

hey,
i have the same problem. I got a looking new universal, I tried to updaty the system, but my battery is very broken, and it crashed while updating. Now, when I try to get in the bootloader, it's crashing.
I hope you can help me!! And I never worked with a windows phone, and I never tried to flash one, so I don't know sth. about doing this...
ebi

There is no backlight in bootloader mode. Go to bootloader, put the screen under a direct light source and see if it says SERIAL or USB (it will be very faint). If it doesn't, the device is almost certainly bricked. Make sure the battery isn't dead and try this while connected to USB or AC charger.
You could also try the mtty method in the stickied topic and see if the device responds at all. It could be a screen problem (long shot though).
Don't forget to remove SD and SIM cards before trying to flash.

Don't think my device is broken, as I successfully updated the ROM, then played with it, forget it more than 2 weeks on my desk. and then never wake up again.
So when battery is dried down, and the internal backup battery (I think it's a supercapacitor), are fully empty, then there is no way to bring it back to life. As the battery only start charging when at least we passed the bootloader sequence, how could we bring it back to life in that case ?
Just in addition to this, I already tried to replace the battery by an external power supply, taking care of the polarity. But without success.
Please advise.
Regards

me too,i put my device in bootloader but led not light(not light screen)

You would need a fully charged battery when flashing even if you had it on a charger while flashing, the charger will do nothing while theres a ROM being updated.

There would be no lights when in bootloader mode nor lights on the screen but you will see SERIAL at the top and V2.01 or lower at the bottom but you would need to look closely as there are no lights.

Fullbrick?

I got a Xperia S here from a friend, he says that the screen suddenly turned off when he was using it. But the notification bar was on!
So he gave me the phone, because I want to fix it.
If I plug in the charger, no reaction.
Soft-Reset - No Reaction.
Hard-Reset - No Reaction (No Vibrates)
Trying connect to fastboot mode / flash mode. No Success.
My last chance is to remove the battery for 5 min and then look if the battery will charge or not.
The bootloader is unlocked and there was OpenSEMC beta 2 installed.
Is this a Hardware bricked phone, or a software issue with empty battery?

this sounds like a softbrick, there are lots of threads on fixing such issues, i seem to remember 1 problem was switching off auto lighting and bang the screen goes blank, holding the power and vol up/down for about 15 seconds makes a hard reboot 3 vibes, then plug in via usb and restart with flash tool running might work. there are lots of different help threads that will guide you through this. dont give up.

But Hardreset doesn't work. I already tried it.

Read this : http://forum.xda-developers.com/showthread.php?t=1849170

Thank but I read already this thread.
I can't remove the battery right now, so I asked you guys if this issue is a Software issue or Hardware issue.
If I can remove battery I will test everything I can and then I'll report.

i think it's hardware issue. cause for it to be software issue it must at least show red led when plugged into the charger.
bring it to service center is a wise choice. but u can try different charger (with bigger amperage output is preferable), and what happen when u plugged it to PC? did the led color shows up?

If I connect to my PC nothing happens.
No Fastboot Mode no Flashmode possible.
I remove the battery the following days, cause I don't have a torx 6 to remove the screws. Must buy one.

Removed Battery and insert it back again. Now trying to charge but no reaction.

If you plug-in a Real charger(Not pc usb), what happen?
Sometimes when the battery is full empty, you have to keep it charges about 15-20 minytes without powering on
Sent from my LT26i using xda app-developers app

Put it in the real Charger, and charged 30 minutes.
But still no reaction. I guess it's a fullbricked Phone now.

[Q] SM-T700 Froze, Powered off - Soft bricked?

Hey guys,
Appreciate it if you could spare me some advice on how to proceed.
So I was watching a twitch stream and all of the sudden tablet froze, and the audio froze as well causing a large super high pitch noise, I hard-reset the tablet but instead of resetting it just turned off, I started to browse the forums and found that a combination of (POWER + VOL UP & DOWN + HOME) would reset the tablet,now what this did for me is turn the tablet on but it was stuck in SD CARD Mode, back again to the forums, read that letting it discharge fully and then it will be able to be charged and turned on, that worked tablet was back doing some various tasks no video again and then boom freezes again same symptoms except this time I couldn't get it to go to SD CARD Mode its very finicky after trying at various times in the day I finally got it to work, same process except this time as soon as it turned on I went into recovery factory reset it to stock, worked a bit longer this time only installed chrome, and it froze again (don't think it was chrome) , rinse repeat and I flashed the latest firmware with ODIN worked fine, I've gotten to the home screen ran through the "factory new" set up and it turned off of me again.
I plugged it in let it charge, came up with battery icon 5% 10% ect, then I left it for a while, I came back and I cant even get it to show the battery percentage(tap power) let alone turn on.
I'm fairly sure that eventually I can get it turn back on but from there I don't know what to do.
TL;DR - Tablet Froze, Hard Reset, Froze again - Rinse Repeat, ODIN to latest STOCK firmware, tablet worked for 5 min before turning off again (plugged in), present situation
Any ideas as what to be causing the freezing and how I could remedy it?
Also sometimes when it froze it turned itself off without me hard resetting it.
Thanks its been driving me insane,
Please do not hesitate to ask me to clarify or provide more information so I can help you help me.

Maybe youve got the loose battery connector problem?

What would you suggest I do, submit it to warranty ? Will they disregard the fact that knox has been tripped if its a hardware issue ?

I had the loose battery connector problem, but the symptoms do not sound the same as mine. I could get mine to boot up, but the screen would flicker and a few white lines would appear before it would reboot itself. I actually started a ticket with Samsung and got the packaging label but, upon further reading, realized that I was pretty much SOL after tripping knox, and didn't want to risk the chance of getting charged for just sending it in. If it is indeed the loose battery connector, you should be able to remove the back cover yourself and fiddle with it. Ultimately, mine needed re-soldering, and I was able to find a local electronic repair shop to do it for me for cheap.
Good luck!

UPDATE: I've managed to get into SDCARD MODE yet again, except discharging seems to get out of it, but once I plug it back in it doesn't come up charging it just black screen, until I hold some buttons and arrive back at sdcard mode. Good times.
Trying various things to get it to boot..
EDIT: Appreciate the insight Squez, I want to exhaust all the other options before opening it myself, if Knox didn't void the warranty to some degree, opening it up should put the final nail in the coffin.
EDIT2: Good news, sort of, tablet isn't dead! after numerous attempts with charge SDCARD mode, discharge, It finally start to charge properly and I managed to get it to boot, worked for a few hours then I left it to charge, and went to sleep, woke up and wont turn on again, but I am in SDCARD Mode again but need wait for it to discharge from presumably 100% ....

[What do you mean Sd card mode? DOWNLOAD mode?
Also no need to let the battery drain.
Just press VOLUME DOWN(not volume up) and POWER together then hold until it restarts.
This is a hard reset and will ALWAYS work unless the device is hard bricked. It is the equivalent of a battery pull.
I continually see here and there incorrect information regarding key combinations, even in so called guides, this forum is even guilty!
Here is what works on the 10.5lte, as far as I'm aware its the same for all versions, indeed pretty much any Samsung device.
HARD RESET:
VOLUME DOWN - POWER.
Hold until the device restarts.
DOWNLOAD MODE:
HOME - VOLUME DOWN - POWER.
Hold until the device boots.
RECOVERY MODE:
HOME - VOLUME UP - POWER.
Hold until the device boots.

I should of posted a photo earlier but here is one I found on google of same screen: (check attachments)
Except UP KEY and DOWN KEY don't do anything, its just this screen, if you attempt to hard reset ect, it will just reload this screen, hence the discharge, then plug it back in and hope it begins to charge "battery icon appears". I have gotten it to boot like this a few times.

Wtf
How did you get to that mode? Looks like its trying to flash from the sd card. Ive seen safe mode but not that.

Yeah its strange as.
I'll have a look at that, thanks.
EDIT: It just finished discharging and now I am on the battery screen.. Usually once it charges here I can get it to boot, what I'm curious is what on earth keeps causing it to freeze up, because in download mode and twrp (gone since i flashed stock via odin) it wouldn't freeze at all, only have issues with it once its booted or charging. I installed a logcat earlier hopefully that should shed some light on the situation,
EDIT2: Well another very interesting thing, the official Samsung charger wont charge it, only works if I plug it into pc or use a non-official charger, strange thing is nothing is wrong with the samsung charger or cable since I can charge my phone fully from it. These have to be some of the strangest symptoms.
EDIT3: Only works through USB port on PC for now, non official charger comes with red X on battery once booted. I assume you can work around this once rooted but that's for another time..
EDIT4: Charge through pc to around 2-3%, boot device, plug into official samsung wall charger and it begins to charge properly.
EDIT5: Hooray back to step one, trying get into SDCARD Mode, same thing happened left it overnight and it wont turn on or charge anymore.

i am pretty sure the HOME - VOLUME DOWN - POWER. puts the 10.5 into the sdcard mode.
my tablet is doing very similar to sunb3ar findings.
have had it come back to me once from sdcardmode.. (let if go flat and starting charging then it would start via normal buttons)
it crashed not long after that. it got stuck in sdcard mode again, but this time none of the drain flat, put on charge has worked.. just blank..
fyi- we try to put it in RECOVERY MODE, but it does not work when in this crashed / sdcard mode state
i even disconnected the battery and then plugged back on charge.. nothing..
today i tested the battery volts, 2.8v , for a 3.8v i thought that was ok. i attached my RC lipo multi charger set to 1amp 3.7volt charge, direct to the - + on the battery- got it up to 3.5v, plugged back in, put the charger on- the sdcard mode (most life it has shown in a week).
still not coming up with 'battery' display to say its 'turn-off and being charged'. just the sdcardmode might disappear and return..
i am currently adding mode charge to battery... will try to HARD RESET next.. since i have not tried that combo yet..
HARD RESET:
VOLUME DOWN - POWER.
Hold until the device restarts.
edit: i took it off 'direct' charge, battery at 3.7volts.. then plugged in normal charger, i got a 'battery symbol' but it had the lightening bolt, not a %.. so i unplugged and reconnected to my direct charge to give the battery more volts. i am surprised that the unit seems to think a battery with 3.8volt as it specs seems to not be like with volts not much lower than 3.8.. could be time for a new battery if we can get this thing to restart

Model G3223 - Charging Issues and Black Screen/Flashing White Light at Boot

Hey everyone,
So, I got a new Xperia XA1 Ultra (G3223) through a trade running stock Android 7.0. Checked everything and initially it looked fine.
Over the last few days, things have been acting weird. Every time I start the device, it gives me a blank (black) screen with a blinking white notification light - it doesn't even show me the boot screen at times when it boots. Just yesterday, I got it to boot by pressing VOLUME UP + POWER after being in that state - but, that's not normal. Does anyone know why in the world my phone does that?
Furthermore, when using the Sony charger that came with the device, it takes over 6 hours to charge and doesn't even show the charging sign while charging. Could this be an Android 7.0 bug or is something seriously wrong with my phone? Only one time since I got it, did I get it to charge normal with the charging sign and everything; it actually charged quite rapidly at that point.
Any help would be appreciated with this, guys, because I'm at a loss. I do want to mention that the device doesn't seem to be recognized by the computer, so I'm not even sure that the cable is original.

Try a new cable and/or charger. (I found I had a bad charger once)
Since you had computer issues, I'd start with the cable. Also check the charging port on the phone for debris/damage.

How is your phone turning on? Power button or inserting the USB cable?
Only thing I can think of is perhaps a stuck volume key placing the phone into recovery or flash mode.
Try turning on the phone with no USB cable attached. Before you turn it on, press the volume keys a few times to make sure they aren't stuck and then power on.

The thing is that it's weird.... For one, sometimes when I use the touch reset/turn off button, it takes at least two minutes to reset, or it doesn't even reset. Then, when I turn the phone on while it's off, the phone sometimes enters into this weird state with the flashing white notification light. I never power on the phone via USB cable, so I don't know, really. Yesterday, I shut the phone off to test it, plugged the phone in to charge it, it wouldn't charge while off, but then hit power on, and then it wouldn't turn on, so I used VOLUME UP + POWER, and then it turned on just fine.

Hi
Happened also to be with my older Xperia J.
Backup your phone (cause you'll lose your data), connect it to a PC (or Mac) and install Xperia companion, then select "repair phone" or something similar (I know the written in Italian version ).
Wait and it will be all fine.

Okay, let me see if I can get it to connect to the computer, and then I'll let you know if I have progress.

I have the same slow charging problem on my xperia xa1 ultra. you could solve it?
