Universal Died while upgrading

hi
i was upgrading my universal, following instructions from http://wiki.xda-developers.com/index.php?pagename=Helmi
after upgrading, on my computer i received an error saying the upgrade was unsuccessful and now my universal is dead
i tried hard resetting, i tried putting it into bootloader mode...
there is nothing on the screen
what should i do?

have you ever entered BL before? most new users would not realise their in BL as it doesn't have any backlight. look closely

yes, i have, it isnt working at all, there is nothing on the screen
when i try to flash the device the pc says error 101 connection error

does your charge light appears when connected to AC power?

nope, no charge light
its sad just about 3 hours ago my device was working perfectly

here's what you do:
start activesync on your computer.
Go to connection settings and deselect allow usb connections.
connect your uni to your computer and push the backlight + on/off button and hold these. Then press the reset with your pen, still holding the backlight and on/off.
The screen should say something about serial or usb.
The backlight will not be lighted so it's hard to read.
If the screen doesn't say anything, unplug and plug in the usb connecter one more time.
Does your red charge led lit when you put it on the wallcharger ?

i tried that, many many times, screen still remains blank
nope, no red light when i plug it into the wall
this is bad, its not responding to anything

When plugged, does it give you a red blink (Charge light) when you Soft Reset?

yes!
yes, the first sign of life, when pluged in via usb to the pc, when i soft reset i get a red blink
any ideas?

Try holding down Light + power for at least 5sec. and while still pressing, do a soft reset.
If you dont go to BootLoader then try to increase the Hold down Light + Power some more.

And BTW. dont get stressed, keep cool.
Youl just **** it even more up if you get stressed, Ok

k, i just tried that, everytime i let go fo the soft reset button the pc says the usb device is not recognized, but still nothing on the screen

lol yeah ur right
thanks for the help

NP. now run the original upgrade for your device...your device is in boot loader right?

nope no bootloader, the screen is completely blank

Look closely, it wont have backlight on, so look really closely.
Remove the SD card and Sim, and just keep trying different time intervals with the "holding down Light + power for at least 5sec. and while still pressing, do a soft reset."
And if you had low battery when you started the upgrade, the use your Wall charger, not USB charger...and let it stay in for 1/2 hour before proceding.
Keep us updated

i removed the sim and sd, and have tried many different intervals, i charged the device all night last night with teh wall charger, still no luck

Hmmmmm, this is a bit strange.
The exact same thing happend to me some 5 days ago.
I managed to get it back with this trick.
Try Soft Reset between every try....just hang in there suddently it wil come to life

Do a ATX-reset/Destat.
Remove charger, battery etc and push in on/off button for 30sec twice. Then push down as many keyboard buttons as you can for a little while too. This way you "drain" it and everything should be reset. Try again.
Works especially well on computers that don't wanna POST. Same thing with cellphones, TV's, remotes etc.
ATX-Reset/Destat. Remember that one. Can solve loads of glitches.
How do I know?
Don't ask I work with these kind of issues every day.

i just tried the atx reset destat idea, it didnt boot it up
ive tried many different intervals now, ive spent hours trying to get this to work
bosjo were u connected to the pc while trying to get it into bootloader?

[Q] black screen / Screen unresponsive - Sumsung Galaxy Tab S 10.5 (SM-T805)

My tablet Galaxy Tab S 10.5 (SM-T805) screen went black. I can’t see the screen.
Touch also does not seem to work. However it’s on. it is receiving calls and other messages. It is connected to WiFi.
Power button, volume button are working but I can’t power off the device cause I can’t see the screen options.
When I plug in to the charging cable it vibrates but does not show anything on screen.
It didn't drop or hit by anything. i have been using it for 3 months now. it just happened by itself or may be by some update that I don’t know.
Please help how to bring it back to life

GUI crashed. Press Power+Vol up+Home (for approx 20 sec).

I tried several times.. nothing happens... any other suggestion please

Power+voldown+home.
If this does not boot, you could try with usb dongle.
Or full run down to empty battery.
Next chance would require to open it.

It's not bricked so calm down. It just had a cyber stroke. It will be fine just let the power run out and recharge the battery so u can turn it on again. Same thing happened within days for getting mine.

yes... I am waiting for the battery to be completely dead. so far its on...taking calls and sms..I don't howmuch % of batter is left cause I can't see it.

I had the exact same problem once....and i had a hunch that the screen was fine, it turned out it was thankfully....but....im aware that on 100 percent battery in standby it can last a good week or so....i was too impatient...so i ran my fingers around the edge of the backing and slowly was able to pull out the back of tge case and unclip the battery...worked straight away when turned on.
But also what i discovered does reset the tablet forcefully is holding power, vol down and the center button at the same time....try it a few times for a minute each time...if successful you might get a message about being in download mode but then just do the same thing again but imidiatly release your fingers once you see the screen go off from download mode or it will just go bavk into it...good luck m8

Have you tried holding down the power button for awhile, like 30 seconds? This should shut your device off....Then take it from there.

Seriously on my tab right now i just held vol down, power and center button whilst on and after 25 seconds screen went black then gave the "are you sure you want to enter download mode." Then i tapped vol up......t805 as well.

Battery completely empty.. tab S turned off, i plugged in the charging cable (1 ) battery meter does not appear (2) Power+vol does not work for me.. if it does.. i can't see because of the dead screen...
i have 2 options now..
(1) send it back in warranty.. this will take a lot of time and they will only fix not replace.. i guess
(2) open it and fix the display.

Hello,
Did you finally got some result?
I have exactly the same problem with a Samsung Galaxy Tab S 10.5. The screen suddenly went black although the light leds (home, back) were on.
I tried different combinations of buttons, usb charging and nothing. The only difference is that now the light leds are off.
---------- Post added at 08:46 PM ---------- Previous post was at 08:32 PM ----------
I have achieved to boot up the device because I have heard the start up sound and some notifications. However, the display doesn't work at all: the screen is black and there is no response when touching it. In addition, the light leds of the buttons are off now even when I push the home button.
Volume keys are working (I hear the sound then touching them).

Hard reset is VOLUME DOWN(left side on a 10.5) + POWER. Hold until it restarts.

That doesn't work, as sarhn007 said the problem is that screen is dead:

But I can't figure how could this happen in a new (2 month) high-end product... I think that I will have to use the product warranty with the cost in time it involves.

This has happened to me twice during the last year. The last time was just ten minutes ago. I tried everything mentioned in this thread. VolUp+Home+Pwr for a looong time. Just PWR for a long time. I saw on my Wifi Router that the tablet was connected, but no screen. What helped me was to do a combination of everything mentioned here. What eventually got the screen on was 1. I turned of my router and 2. Home+VolDOWN+PWR for (what I believe was) 10-15 seconds. Then I got the choice to do a normal restart or a device reset. If you come this far, be sure to press VOL DN when asked. Otherwise your data will be lost. Obviously, I can't say if the router pwr off was necessary or not.
What's really weird is that my LG G3 went into a boot loop at about the same time (less than five minutes apart). They are not connected other than using the same router. I've had my LG G3 for exactly one year without ever experiencing a boot loop. The LG G3 is rooted, but my SM-T805 is not.

It's easy fix, most of the time due to loose LCD cable. If you can hear anything on the background but blank screen, 99% is loose cable.
Remove the back cover, disconnect and reconnect LCD cable, make sure it's fully inserted, then secure the connector with tapes. Test by plugin to charger, press the HOME button.
If you do correctly, the battery icon should show up on the screen. Then put back the cover, you're done.

[Q] Display and touch screen major issues following lollipop update.

Problems with my Samsung Galaxy Tab S 8.4 SM-T705:
1st: October 2014
2 weeks after buying, my tablet's battery drained overnight from 45% to zero. Next morning, I turned my tab on after charging to find out that the Tab starts but without any Samsung GAlaxy Tab S logo or Samsung Logo and the Screen has turned green, rendering it difficult to read in auto brightness mode or low brightness mode.
I restarted the device 2-3times and the device started working normally. This was my 1st device restart. I never used to power off the device before.
In 1st 6months, this greenish display problem n logo problem occured 2-3times, and i ignored it, because, it used to get resolved by itself with restart and I had no service centre in and around 50km to my work place.
2nd: January 2014
My device all of a sudden stopped working.. actually hanged.. I managed to turn it off but failed to restart it.
Later I realised that the device has restarted, but the screen was not responding when the screen blinked for a moment with the opening of book cover.. and the back cover of device was warm..
Googling taught me the way to access recovery screen n I opened recovery mode with "power+vol down+home key" and pressing vol down in recovery screen to restart tab.. again the tab started working fine..
3rd: Lollipop update: May 2015
I did Lollipop update. The device was smooth to operate at first. But gradually, i noticed that unlocking the tab failed to light up the display everytime, just the soft keys lighted up. But one day, the device freezed with no response from touch screen. I was unable to switch off the device also.. I had to drain the battery by playing music using S voice to turn the device off. "power+vol down+home key" too was not working.
On googling, I learned to reset device with "power+vol up+vol down" keys pressed together. finally the device restarted, but the device used to hang occassionally.
Googling let me know that i need to factory reset device upon firmware update for normal functioning, which i didn't do after update. so, I backed up my device, uninstalled many apps to make the device run a bit smooth and did a factory reset.. Resetting didn't improve the situation much, but now, the device display failed to light up on a regular basis on unlocking most of the time..
Now the situation is that, the device turns on, finger print scanner works, all apps n everything working, but display remains black, and touch screen is not responding.. using sidesync, everything on Tab can be accessed via laptop.
Tricks tried:
1) Factory reset
2) power+ vol up+vol down
3) power+ vol up+home key
4) power+ vol down + home key
5) Power off using sidesync and then restart
Results: All failure. Everything works but the display never lights up normally..
Plzz help....:crying::crying:

Bump. I'm starting to have similar problems with my SM-T800 running 5.0.2. I open the cover and the device fails to turn on. I press the power button and the screen stays black but the notification bar turns on. I can shake the crap out of the device and the screen stays black but I can see the notification bar flicker. Driving me batty.

If i had any problems like you guys, I would just return it to the place i bought it, for a refund or replacement or even a repair, post it to the service centre if it`s too far to travel too.
You problems sound like battery and or loose connector inside your tablet, it happens frequently on Samsung tablet for the connectors to come loose, if the tablet is dropped or twisted, no outside damage might be seen.

Phone not turning on.

Hi. So after a long wait I got my Zenfone 2 ZE551ML today. The first thing I did was turning it on and it turned on normally, then I proceeded to make the initial setup (logging into google account, etc) without any problems. Then after about 10 minutes of use the phone suddenly turned off with the battery being at around 35% and didn't want to turn on again. I read that old firmware (like the one that comes default with the phone) had battery display errors so I thought the phone had run out of battery, so I charged it for 8 full hours and I unplugged it now. To my surprise the phone is not turning on either. The only way I can make the screen show something is by connecting it to the charger, it vibrates and displays a white battery icon, eventually changing to fully green (fully charged battery, the green led indicator also appears) only to disappear like 3 seconds after. Can't turn the phone on while charged and can't even make the phone show the battery icon again (unless I unplug and plug again, repeating the cycle). So, what can I do to turn it on?
Thanks in advance.

I have a feeling that you did not hold the power button long enough. Disconnect the charger first, and wait for about 10 seconds. Then, hold the power button for at least 6 seconds. The phone should then vibrate and then you may release the power button. Other reasons why your phone may not seem to be turning on at all might be due to the back cover not being fully locked in, thus not making any contact with the power on the motherboard itself.
Do report back the results.

I did. Doesn't work. I also removed the back cover and pressed the power button with nails with no results either. Personally I think there's something to do with the power button as it doesn't even responds while charging (pressing it should display the battery icon) and the only time I could use the phone it didn't work to wake up the phone or setting it to sleep, only double tapping worked. What is strange is that it worked the first time I turned on the phone though.

Are you able to get into FastBoot mode? If so please try performing a hardware reset including wipe cache partition. Please see the following:

Stuck in low battery boot loop

Hello, Huawei gadget friends.
My watch started to go in to a "low power boot loop" a week ago so I left it alone hoping a full drain would restore it back to working condition, but alas not.
So now this is the situation:
1) press button, nothing happens
2) connect to power shows the charging icon (white battery with power sign) and then after a few mins commences a boot loop as follows
3) from the charging icon, then gives the "Device software can't be checked for corruption..." message
4) followed by the red Huawei logo, then a single vibrate and then back to step 3 above
5) removing the watch from the charger stops the boot loop but then shows the low battery icon (white battery with one bar).
In one or two occasions, I saw it boot up to the colorful spinning 4 android wear logo, but did not complete (did not show "Android Wear" before rebooting again.
I have tried getting it to recovery mode screen or fastboot but without success -- I keep getting the second buzz without fail.
When the beta of 1.5 came out, I tried it, but since then, have wiped my mac and don't have the adb/fastboot software anymore. From reading the forums, there is now some new software called TWRP. Please advise what I can do.
Would I be right to suspect that it is some battery problem? Is it beyond help? :crying:
Thanks in advance!
MMM
Edit: I have also left it on for several hours charging (and rebooting constantly), thinking that perhaps it is just low battery -- but no success.

I'm experiencing the same problem, i turned it off yesterday at 17% and connected to the pc this morning to charge. I immediately noticed that it started looping with the white icon and it doesn't turn on, nor boots into download mode.
Have you found any way to restore it?
Mine doesn't show the red HW logo, charged for some hours and nothing.
I noticed that the pc see that there's something connected, but keeps saying "USB not recognized". I don't know what to do, i may open up and disconnect the battery
EDIT: SOLVED, it was just the cable that broke somehow. I soldered a new cable to the circular base but that didn't work, but as soon as i received this i connected to the pc and started pressing the button randomly till it showed the battery logo and started charging

I got this when I plugged it into my laptop. Plugging it into a dedicated USB charger solved my problem - I suspect the power rating on the USB socket wasn't high enough to charge effectively or that the USB socket is faulty in some other way. From what I understand, not all USB sockets are equal in that some are suitable for high-drain devices, some not so much. So trying another USB port on your computer may also help (Unfortunately at the time I was backing up to an external HDD on the other USB so that option wasn't open to me).

guyz, i have tried my method it actually worked on Xperia X Perfomance
When it goes to Bootloop for Drained battery, i just plug the cable and perform activity block method By pressing and holing power and both volume up and down and when it hits the 1st viberation i just simply release the key. (remember dont hold it too much long after 1st single viberation just release the keys ) and your phone will go to block activity mode. charging light will change it colors from red to blue.. after 2 minutes just press power button then you ll get another viberation and your phone will be seen as charged 2% and then it will be normal again...
i think it happens when battery drained and phone is unexpectedly trying to go boot in first place.
thank you
