[Q] M601 will not boot - Xoom Q&A, Help & Troubleshooting

Hi,
My M601 (Wifi) used to work fine but one day when I charge it just doesn't display any more. I can see it can charge but when I press the power button it shows nothing.
Is there any way I can troubleshoot to find where is the problem??
Thanks.:crying::crying:

Is it defo off?? Is it not a screen of death?? Hold the power and vol up button and see if it resets. Do you get splash screen or nothing after doing this??

Nothing happened after "Vol-up, power" or "Vol-dn, power". No screen at all.

I faced similar issue , the only thing that was showing was the notification light when charging, after reading all the forums i decided to plug in a micro hdmi cable to the tv so that i can see if the xoom is working.
and yes it was working perfectly fine!!! i could see the screen on tv and the touch was also working but i wasn't able to see anything on the screen(XOOM)
then i finally unscrewed the 2 screws and opened up the xoom , i removed the lcd connection and plugged it again! and THAT WORKED!!!
REALLY!!! TRY That!!!
here is a photo that can help you , you dont have to dig up the whole system, just disconnect the lcd cable and plug it in and be patient please!

[Q] TF300T wont turn on

HI,
So, grabbed my TF300T one day and it would turn on, "no prob" its just out of charge, so charged it (led on the power button went green) went to turn it on and nothing! tried soft and hard resets and still nothing!
Does anyone have any ideas or is it just dead? its stock, just unlocked (form ASUS tool).
Cheers.

Try using the reset hole on the left side of your tablet. Hold that down for varying lengths of time.
Does the light still turn on when you plug it in?

I have tried the reset button but with no results.
Yes, when plugged into the mains i get the orange and then green led.
It could also be the power button shiftet out of place. Remove micro sd card and remove the back cover. Ask someone for help if you don't feel comfortable doing this yourself. Be careful with the hdmi and audio connectors. A pry tool is useful but not required.

Done that too. I had a new motherboard from the last RMA. I think I will just have to face facts that it is now dead

Last suggestions. Service switch is off. (But that kind of don't happen by itself).
Have you checked if it possible to put it in apx mode? Have you done the nvflash/wheelie/flatline backup?

[Q] T699 reboots on charge

I own two T699's, one looks a bit wore so I'm trying to replace it with a better looking one.
Found one on ebay but from the first second it reboots when going into the 'battery' screen (charge only when turned off)
I thought okay.. maybe a software issue with the phone, but now I already did the following:
- Odin flash it to an older version
- free Unlock the phone (using an european operator, this worked fine)
- OTA update to the newest
- USB didn't work anymore?? -> Odin to the newest
- USB working again, still unlocked
- ODIN TWRP and install CM11
- CM11 boots just fine (connected to the charger)
- CM11 gives no charging info, reconnect USB, now the charging icon is working...
- seconds later.. reboot
- works again.. no charging, reconnect charger... seconds later reboot!
-turn off, connect charger, see the charging icon showing up (full screen) reboot .. reboot.. reboot etc..
-turn on (no charger) check battery info in CM11, see this:

weird gap..
So my conclusion is that this phone works perfectly when it's not charging.
Is this a thing you can fix with software?
If no, but there is a hardware fix, i'm also willing to try it.

As in in the settings??

I also found another topic (not related to T699 but other samsung phone) same issue but they guy opened it up and had water damage.
He was able to fix it by cleaning the pcb's etc.
Since I have experience with this I opened up my T699..
And to my surprise there is a lot of 'sticky' stuff (think it's Cola or some other soda) so i'm cleaning it now with some PCB cleaning solution.
Will let it dry for today and hopefuly it's working tomorrow :angel:
Made some photo's as well to contact the ebay seller.. because this is not as advertised.. :silly:

Could do with a little help, I think my N5 is dead

Hi all...
I think my N5 is buggered.
I was at a festival this weekend and my phone battery ran out so I left it in my bag for more of the weekend. On the drive back it was working fine as I was using GPs, making calls, using Gplay without any problems. As my GF wanted to charge her phone mine ran out again by the time I got home and I went to charge it as it was down to 2% but when I plugged the charger in it would not charge. It would start charging for a second then stop for a second and then start again. So I unplugged it and went to give it a re-boot and the screen came back on corrupted like this -

I have holding the volume down and power button to get to the fast boot menu and the screen does the same thing but this time while i'm holding it the screen with turn on and off wile vibrating 5-6 times before turning off.
I have even tried using fastboot to flash the recovery image onto the phone and it says everything has worked but again I get the corrupeted screen when I reboot.
Anyone seen or know of this problem? Or is it what I expect and it's got a hardware issue and needs to get repaired?
Thanks in advanced for any help or suggestions.

It's a problem with the flex cable, the screen, or possibly the motherboard.
A few people have had this issue.

Lethargy,
I had a feeling it was going to be a hardware issue. Thank you so much for the help... I'll get it sorted under my insurance then and get myself a temporary phone until then.
Cheers

when i try to attempt to get into download mode i cant get into it it just shuts off and i plug it in again and in around 5 minutes it will go back to the screen on the picture
i have installed the samsung drivers and kies, and i still cant get it unbricked, if possible, give me tips on how to resolve this issue, because a extra tablet could be handy

Keep it in charging for a few good hours and see if it goes somewhere in download or recovery. A hard brick won't even show a battery icon.
Without a working download or recovery mode, there is hardly any help.
Tried with another set of charger and cables?

Did you replaced it yourself or somebody replaced display for you ?
Maybe you disconnected cable or something, it is very easy.

well I did it myself. Fortunately I hadn`t put the back cover on and tried turning the phone on....
a repair would have cost me around 180 $ so I ordered a replacement part for 70$ from wtrigs, I have already done that successfully with my Z2...
today I put it apart again, checked every cable or connector, still isn`t working, and also the VOLUME DOWN buttown isnt clicking when pushing it...
I think I broke the main flex cable for all the buttons (POWER, VOLUME UP & DOWN, CAMERA) when I removed it using some tweezers...
here is the part that I think is broken:

If buttons doesn't click maybe you didn't put the white(check picture) part back or its not mounted well...
