[Q] [D2LTE] CM11 Sudden Death issue

Hey All,
I'm currently on the CM11 04/22 nightly, and have made it all the way up to the 04/27 nightly to try and resolve this issue and have not been able to. Basically - the sudden death issue has been hitting me very hard - I can't use my phone at all.
I understand the 04/11 nightly is stable and doesn't have this issue, howevery CyanogenMod does not have this on their website.
Does anyone have this install available? (CM-11-Nightly-20140411-D2LTE.zip)
Thanks so much in advance

I'll be using the phone (say checking my Instagram or reading a book on Play Books) and the screen may be on for about 5-6 minutes. The phone will suddenly shut off on its own. I'll start it up and then shut down again when the phone is loading. It will also sometimes say it has 1-2% battery when it really has 45% (which is what it shows when I plug the phone in).
Hope this clears it up.

I had the same issue a week back. Was the most frustrating thing ever...
I finally narrowed it down to the power button. It actually had to do with the power button switch which is soldered to the motherboard. The power button was super sensative, therefore being engagded at all times, causing the phone to hard shutdown every time I tried to turn the phone on.
How I fixed it:
1. Opened my phone up
2. Broke the switch off
3. Done
Now I use my phone without a functioning power button but it was a quick and free fix so it doesnt bother me.
If I decide to do so in the future, I can also solder a new switch back and get the power button working again.
DO NOTE: This might now be the issue you may be facing, so do your research
Finally, I watched this YT video which showed me how to break the power button switch and eventually fix my phone: https://www.youtube.com/watch?v=3Glllc7bEJs
Good Luck

I'm fairly confident that this isn't the power switch. And if it were I'm not sure how comfortable I would feel breaking the power switch off.
The thing that begs me to think this is a software issue is that I'll have 45% battery, the phone will die, and then I'll try to turn the phone on again only for it to tell me I have 1% battery left. I'll put the phone on charge (after it dies again) and it will say charging - 45%.
Anyway I've rolled back a few updates and it seems to be fairly usable now...

Try cleaning the USB port real well and don't use a cheap cable. Use a needle and make sure there is no lint packed in there. These things can cause the phone to cycle itself even when not plugged in. I've fixed several doing exactly what you describe.

Stuck on lock screen

Wondering if someone can help. My boys nexus 7, screen is unresponsive and is stuck on the lockscreen.... It seems the problem happened after a system update downloaded(shown in the image)
Anybody any idea how to fix this

Try resetting the device by holding the power button.
You could also try to safe mode, by holding the volume down button while booting (safe mode text should appear upon bootup in the bottom left corner).

There are at least 3 possibilities.
1. On some, the touch responsiveness decreases with the battery being drained. In other words, the lower the battery percentage, the more unresponsive the touch becomes. Reaching a certain low level of battery would kill touch completely. But this usually occurs with a tab that has had responsiveness issue all along. If it's something new that takes place only at the downloading of the update, then it might not be. Just to make sure, turn it off completely, charge it fully, then turn it on again.
2. The touch problem just occurs out of the blue. You want to make sure the hardware is not at fault. The only way to do this is to remove the back cover and reseat the two-pronged amber cable from the digitizer, and the white/silver cable connecting the daughter card to the main board. If there's a problem of this kind, no amount of software workaround will cure it.
3. The update is the culprit. If this is the case, the only thing to do would be to flash another rom (preferably a custom one that has more or less been sanitized by a known dev.
If you have a lot of data you're not willing to part with, then you can try an OTG USB mouse to navigate and allow the update to install to see if the tab would return to normal after. I wouldn't advise this route since I've heard and read a lot about people bricking the tab from taking automatic updates. Stay away from anything official if you can help it.

Galaxy Note 10.1 2014 Edition not booting up/ firmware issue

i have this awesome tablet for a good time. it's the wifi edition with 16gb black. this week i noticed when the tablet goes on rest mode, the screen turns dark (as usual) but when i want to us the tablet, the screen remains dark. i could hear the notification. i had to restart the device and quickly start using the tablet before the screen goes dark again. i noticed the message on the screen stating "firmware upgrade encountered an issue. please select recovery mode in kies and try again." i connected my tablet to my laptop and no success. i called samsung and they told me to press the vol+, power button & home key for 40 secs and nothing happened.
i am turning to the great forum to ask for help. all my stuffed are on the tablet memory. at this point i don't care about it as long as someone can help me bring my awesome tablet back to life. i never rooted it at all.
please, help me.

I'm not the most knowledgeable when it comes to this kind of thing, but I do know that on the Galaxy Note 10.1 2014 edition booting into recovery is slightly different than it is on most other Samsung devices. Where most Samsung's are power button + volume up + home key (like Samsung rep said), with the Note 10.1 2014 edition it's just the first two, power + volume up. Here is a link that will describe step by step how to do it as getting the timing right can be a little bit tricky if you have not done it before. http://mobileaddons.blogspot.com/2014/05/how-to-hard-reset-factory-reset-samsung_9205.html There is probably the same instructions here on xda somewhere if you do a search... I just googled it and that is what it gave me. If you need end up having to boot it in download mode, thats the power and volume down keys, just push and hold both (if I remember correctly). It sounds like it may have attempted to update to lollipop but the update failed for whatever reason, but I could be wrong. What exactly did the Samsung rep tell you to do? a hard reset/factory reset (which will wipe all your stuff), or did they say to attempt the update via kies? Just curious

hi thebadwrench, i followed and tried the instructions you shared and my tablet does not respond at all it stays dark and does not even respond when i plug the charger in. there are no feedback or sounds at all. i do not know what else to do.

Hmmmm. You may have a hardware failure if it is not responding to anything at all. I know others have experienced problems with the screen flickering and/or quit working as result of a loose or disconnected electrical connection internally. It might be worth removing the rear cover of your tablet to look for something like that. I don't know how comfortable you'd be with that, but it's actually pretty easy to do. I recently replaced both the battery and charging port on mine and posted some pictures in this thread here http://forum.xda-developers.com/galaxy-note-10-2014/help/q-instructions-tips-replacing-usb-t3345093 I'd just disconnect both ribbon cables and reconnect them. While your in there (and this has worked for some people) simply unplugging the battery for a few minutes then reconnect it. Kinda resets the tablet (you shouldnt lose anything saved on tablet, assuming your able to revive it). If your not comfortable with digging into your tablet, take it to a phone/electronics repair place and for a fee they could do it for you, or better yet they may be able to diagnose the problem definitively. Other than that, I'm out of ideas. Sorry to hear that your having issues, let us know what happens

I followed the steps and my screen is back on but it is stuck in recovery mode. It shows the green Android guy and says downloading but nothing for the last 10 minutes. What do I do?

Good to hear you got your screen back on. As for it being stuck in recovery mode... just to clarify, what exactly did you do to get it to the screen its on now (i. e. did you just attempt to power it on, or pwr + vol. up buttons, etc). It might be best to just send me a personal message...

How do I send you a personal message?

Just click on my username, then click "send message"

Screen remains black but calls, text messages and WhatsApp messages receivable

I bought my beloved Huawei Mediapad M2 in January 2016.
After a recent sabotage, I had to send the tab for repairs because the LCD wasn't functioning. But a few days ago, my Mediapad M2's screen flickered although I already retrieved the tab from our local Huawei authorised centre and then the screen turned off when I received a phone call from my family so I can't pick up the call because I can't see whatever that is on the screen, how to fix this without having all my data becomes wiped out again? Yes, I have a lot of work saved in this tab.
Before you ask further about memory card, thing is, nope -- I don't use any, all files are saved directly into the internal storage of the Mediapad M2. I know the tab is still working because when I tried calling my number (which is in the tab) from another phone, the tab rings. So does when messages come in. And when I plug in the headphones I can listen to music from my tab.
I want to backup my files before re-sending the tab to the service centre because they might wipe off all data again upon rectifying the issue, but before that happens, how do I suppose to do the backup when I can't even see what's shown on the screen (because the Huawei HiSuite software installed in the PC requires confirmation of the tab being connected to the PC by touching on an OK button which is supposed to show up on the tab)?
Please help, thank you in advance.

I have the same problem
Did the screen turns like grey after a while ???????

Hmmm.... this seems to be a fairly common issue, from what I can see in my searches. Most of the threads I saw in my searches (see "references" below) recommend trying the following things. DISCLAIMER: I have not tried any of these methods; you try them at your own risk.
- Try a hard reset - keep the power button pressed until the phone reboots.
- Press VOLUP + POWER and see if that fixes the issue.
- Press VOLUP+VOLDN+POWER to boot into recovery and see if that fixes the screen issue.
- Let the battery completely drain (do not charge it for a couple of days) and see if it fixes the issue (note: this is a modification of a solution where people remove the battery, let the phone sit for 10 minutes and then replace the battery. Since we cannot remove the battery on the M2, we should just drain the power).
- This may sound stupid, but give the phone a couple of smacks. If it is some loose connection in your screen connector, this may (temporarily) fix the issue.
If everything fails, you may need to take it back to the store and allow them to factory-erase it.

I got it
So it's a problem on the flex cable that conect the motherboard to the screen, it cost like 9$.
And if when your tablet was ok you had "automatic scyn" on, when you reinstall all over again if you pay attention from what google say, it's like have your tablet with the same things.
I have this problem too

Did you already solve this problem?
I had the same issue. But you have to repair it yourself. Or have it done by someone who knows how to do it. The touchscreen is attached to the body of the tablet by a connector cable. This is probably broken.
You can order spare parts for this tablet online.
I found mine on ebay and AliExpress.
It is also possible the touch part of your screen, or the whole screen (LCD part and touch part) is broken. All parts are easily replacable!
If you need any further help on how to do this there are videos on youtube.
Good luck and I can post more specific details if necessary.

I need help to boot pls (broken button/old rom)

Hi,
I've got an old OP3 wich my son is using. The problem is that the power button is broken/not working. Last update was made years ago (maybe 4 or 5..), and there is "Tipsy rom" installed (Android 7.1.2 ).
So when battery is empty for instance, to put the phone on I had to put the phone on charge, and then the screen(s) appear(s) that it should "boot in 5 sec" (see attachments). It did work before, but doesn't anymore... ! Don't know why.. ?!
I've searched how I could do but I don't find an answer.
To be clear : adb is enabled but the phone isn't recognized (or only while in recovery) so I can't use code lines (I also tried in different usb slots / on different pc). And when I put it on charge, I still do have the boot screens that say "if no key pressed : your device will boot in 5 seconds", but instead the charge screen appears (with battery charging). I've tried to disconnect the battery, the volume button, the motherboard.. with always the same result.
Could someone please be kind enough to give me advice on how to boot the phone ? It'd be really appreciated !! Thanks.. !

It is difficult to assess the situation without carefully checking the operation of the switches, whether current is passing or not. If they are not damaged, the cause may be a defective electronic button controller on the motherboard.
Since it is currently not self-starting, there could be more causes.
I suggest replacing the switches with working ones. This will be the first,cheapest and maybe the only option for diagnosis.

Thanks for your reply !
I didn't test if current goes through because the battery must be get out to check it (I removed batteries before and had "bent" ones often). So you're right I don't know if it's the button switches/cable, or worse (contact/motherboard...).
That said, I would like to try to find a way to "force" boot, for exemple I've tried to hold volume button while/between/after boot screens appear, but yet I always come on the screen wich allows to choose from "power off, restart, recovery, fastboot mode"... (with volume button). I don't understand why it rebooted before (like the screen says "after 5 seconds") as it worked well before but refuse to now..
I appreciate your input, many thanks ! If you've another idea... ? . Thanks anyway !!
