Very FAST battery drain while SD CARD unmounted - LG Optimus 2x

Hi,
I needed to read/do something with my sd card in my PC.
So I unmounted SD from LG O2X, I formatted SD (with O2X) and I went far from O2X (leaving O2x on).
I had about 30% of battery.
After very short time (10-15 min.s) I comed back and I heard an alarm on O2X:Low battery!
3%!!!!
On notification bar there was a message like "Put an SD Card"..
I suddendly shut down and now I'm charging it..
What happened?
Did I make a mistake?
Maybe there is something wrong with SD driver or it is a normal behavior on Android? Maybe It does not support Hot swap?
I can't understand!

If I read the manual correctly, you must switch the O2X off when placing\removing the microSD card.

Maybe because you just unplugged it, you caused it to do a repetative cyclic redundancy check.

But I umounted it!
But.. LGmaniac2003 is right: Manual says to turn off. So: my fault.
Well.. It's a little bit strange but i learned a new thing!
Thank you!

sounds kinda odd. Can you do exactly the same again? and just monitor battery behavior, at least u'll be sure if that is causing the battery drain

That is retarded.... if you have to turn it off LG should have removed then unmount button in the software.
I expect buttons to do what they say they do,

Is better than having no SD-Card slot at all

i agree with gensplejs if so, it does not make any sense at all the unmount button :S

You'll right.. But battery was very HOT! It has never been so hot!
So, sorry, but I would not damage my battery.
If, in future, I will need to use SD in PC I will test that (It is a good thing to do!).
In the meanwhile maybe I found what went wrong.
As I sayd: I unmounted it.. And that is safe (I'm quite sure).
THEN I formatted it!
When It finished I was in a hurry, I was distracted..
SO, MAYBE SD was MOUNTED again!!!
And that was my error: I pulled SD out!
So you CAN (IMO) unmount and take it out!
It is safe..
Well They could use a GPIO to detect card insert.. But they had to save space/power..
Maybe that is the reason why you "have" to power off O2X to swap SD!

Unresponsive (bricked??) HTC Touch Pro 2. Help please.

Ok, so I have encountered something NONE of us EVER want to encounter. My phone has died. It will NOT boot up on battery power and is now cycling in the tri-color screen over and over again. It does this when plugged into USB port and wall outlet. I have the HTC Euro stock ROM on the SD card in the phone, trying to get it to reflash. It gets to the screen : "loading" and "checking" ....but then boots down again and cycles all over again.
I flashed the NRG 10/11 Photon ROM. I have the first HRDSPL from Olinex. My phone is the Euro version, unlocked, unbranded. I use TMobile in the US. .
Please, there has GOT to be someone out there that can help me. You guys are really sharp!! Please ....I need my phone!
I cannot even do a hard reset either. I push the power, send and end button all at the same time. I get no response.
What are my options here? Thanks in advance.

1: So if when you pull out your battery it goes off. And on reinsert, when you try to turn on or hardreset ie: hold the TALK/SEND, END and POWER buttons until you see this message on the screen.
"This operation will delete all your personal data, and reset all settings to manufacturer default. Press VolUp to restore manufacturer default, or press other keys to cancel."
At that point you release the buttons and press Volume up to perform.
It doesnt do anything?
2: As soon you do the AC adapter in or USB power, it starts cycling on his own? If not, try to hardreset then.
3: If you wait like 30 minutes, with cycling on USB on PC, can it hardreset out hisself? Ive readed another guy who had issues and somehow it fixed itself.

sorry to hear that, have you tried taking the battery out for few minutes & re-insert it in then connect your phone to PC to see if it let you re-flash again?
good luck m8

I waited all night long for it to do that. No luck.
Now I get to the point where I see where it recognizes my .nbh file and has a splash screen. BUT......it will not go any further past that now. I press the power button to continue, but it just cycles again and the whole process starts over. I see a reallllllllllllly quick sliver of the update bar, but it disappears fast b/c of the recycling process.
Please dont give up on me. Thanks.

I saw in another thread that you have tried removing your SIM card with no success. Have you tried without the SD card as well?
Also, does pressing the hardware reset button under the battery cover do anything?

I do not have the SIM card in there. I never have flashed with a SIM card in there. Always read to take that out when you do that.
The SD has to be in there b/c it is the only thing that has a shot of getting the ROM to the phone. Active Sync wont connect b/c phone keeps powering on/off with its cycling issue. So the SD card must be present with the .nbh file on it. I am just in hopes that it will read it somehow. I am sooooo tired of pressing the power button for it to continue, only to have it turn right back off.
ps, reset button does nothing either.
ugh.
Aaah sorry, didnt remeber who was talking about it... There were few cases like that if I remeber correctly...
Ive been here since TyTN, does it make 4yrs or something? I have never heard anything like this.. Because the phone goes to the 3 color screen mode, Im pretty sure someone with skills will come up with a solution, but it might take time though...

So the 3 color screen mode. Exactly what is its purpose and why does it keep cycling over and over and over?
Its the bootloader, you should PM Olinex...

Certainly, but I was curious to find out if taking the SD card out had any effect on the cycling or your ability to hard reset.

I wish.... It just cycles...over and over and over. No matter if the SD card is there, thrown across the room, or crushed in my hand. lol
I always flash with SIM and memory card (as I use UC almost everytime) and never had any problems with any device.
PM the board guru's about this and you will learn more in a single message than you will from this topic in a week.
Last post maybe came out little harsh. I only meant that your problem sounds so serious, that you should contact the gurus before you do something that could even make the matter worse...

Hey, it's ok. I didnt take it as harsh. I have contacted cmonex. I am in hopes she can help me out. I need to put an APB out on ALL GURUS!!
Actually, that is why I posted here.
I've noticed during the flashing process it doesn't take power from USB. What is the status of the battery? It occured to me that it might be power cycling because it's going to a part of the process that only takes power from battery and there isn't enough to do what it wants to do. (+50% ?)
Just a thought ... good luck dude I hope you get it sorted.

Yes, I thought of that as well. But I had it plugged in all night...but I have no idea if it charged b/c I cant see the screen that gives the battery's status. ?? So, I dont know how to get around this part of it. I KNOW for a fact that my battery was low when the phone died. I dont know how to get it charged back up to do this type of diagnostic test.....??
Maybe it's not getting a proper charge if all it's doing is looping ... I figured you wouldn't be able to get battery status after I posted haha ... But it is interesting you said the battery was low when this all happened.
Do you know anyone near you that can lend you a fully charged battery? Does it boot up immediately if you take SD card out, put battery back in and plug in USB power? If you can't get it to where the phone is off and charging with orange light then a spare battery could be worth a try.
Don't worry dude I'm sure cmonex or olipro will have far more useful advice but no harm trying in the meantime

[Q] Does anyone know why my SD card disappears? (SD not detected)

I got a brand new SGS. It was one of the new models that got replaced from the disfunctional 3 button combo phone that was in canada (i9000m)
The GPS and stuff works perfectly too. So I'm happy.
But I have to reboot my phone like 5-10 times a day because the SD card goes missing (can't use camera etc. says not enough memory)
Anyone know the fix to this ? Why does it disappear ?
I haven't rooted or done anything to it -- it's vanilla right out the box.
Your issue is not new to me. I also had this problem, but the only thing I could do was to pull my sd off and reinserting it, regardless of the uncountable reboots. I got my phone in July and since then it happened about two or three times, but from five to ten times *a day* is way too much.
Try with another sd card (it may be defective). If it's still bugging you, I'm afraid the best option would be to give it back to the shop to send it for warranty repair (or immediately getting a new one, depending on the shop).
Please, let me know how it ends.

First, this thread should not be in the development subforum.
Second, to answer your question, once you connected your phone to the computer, you will not be able to access both your internal and external sd card. My advice is that you go download and rtfm.
Go to the Q&A section, and you will be able to learn more.

Random Reboots, unable to complete a boot

OK Guys, here is my issue... I searched the forums and had no luck for what seems to be my problem, nor did a google search return anything.
I got my Nook back in Febraury, and it worked great, right away wound up putting NF 0.6.7 on the eMMC and life was peachy. I hadn't been using it much, had been waiting for CM to get to a stable release so I could put that on there and call it good.
Anyways, I'm using it one night, full battery, I turn the screen off, head to bed. The next day I try turning it on, nothing happens, tried all the key combinations, but wouldn't start. My microSD adapter was broken and was waiting for a new one so couldn't try much.
Just got the adapter yesterday so I went ahead and made a CWR bootable SD card (not ext4) and booted it up, but it was doing the weirdest thing, The whole screen was flashing, like how the screen will turn black if you press the power button while in CWR, it would blank the screen then come back momentarily, and then probably 10 seconds into it it rebooted itself. Thought this was pretty weird so tried booting again with the same results.
My next step was try download the SD image again, reburn it and try the process again. At some point I wound up trying the ext4 image because I wanted to install CM7 anyways. One time I was able to boot to CWR, and it didn't seem like anything was wrong, so I thought life was grand, wiped data/cache and installed the CM7 zip liek the instructions stated. Rebooted, nothing. Rebooted with the SD card in again and it was back to its old antics. Anyways, after many reburns and tries, I was able to get CWR to stay up long enough to flash the repartition boot with stock image. When I rebooted it would get to the N screen, and then bootloop like it's supposed to, did that 8 times, got to where it shoudl Factory reset itself, got the installing screen, and the Nook rebooted right before it was about to finish!
So ever since then it's been a struggle of trying to keep it up long enough to flash a stock zip, but I have had no luck, it literally reboots within 30 seconds of being in CWR. Tonight I'm going to try making a CM7/NF SD card to see if ti will stay booted solely off of the SD card, but not holding my breath since CWR won't stay.
To me it sounds like a hardware problem, all the keys work fine tho, power to boot and turn off, I guess i cant test volume keys but the N works just fine too. Didn't drop a glass of water on it, didn't leave it on top of a furnace or anything, I have no clue.
Crappy part is im outside of BB's return perios, and even if I wasn't, I threw the box away last week So what do you guys think? Am I totally missing something? Is it hardware? Can I send it back to B&N for a warranty claim? Not sure if they'd be able to tell it's been messed with since it appears stock now, and I don't feel like defrauding them, but if it's hardware it would have happend with or without a custom rom on there. Sorry for the long winded post and thanks!
does it behave when hooked up to your computer via usb? is it possible to complete the flashing using adb?
Hi,
It also sounds like the electronics might be intermittent - have you given the
unit a 'thump'?
Cleaned the uSD connections on the card (and maybe on the Nook?)
Probably not it, but in your long description above, you don't mention reformatting
to EXT4 all the correct partitions before installing CM7.
Good luck!

Holy crap, it behaves perfectly when hooked up to the computer, i can mount it and everything, but as soon as i unplug it, it's up to it's old tricks, dimming the screen, going back to the lock screen, acting like the power button was pressed. I don't get it at all.. I'm going to do some research on pushing the partitions via adb...
spoke too soon, back to rebooting every time it gets to the N screen

What kind of 'thump' do you recommend? lol, i tried cleaning the connectors, no luck, i actually didn't format any partitions to ext4 before i tried flashing the zip, i thought flashing it from an ext4 compatible sd card was the only thing you had to do? please tell me i missed something and we can fix it!
OK one more reply here..it seems to be behaving fine when its plugged into either usb or outlet, its almost like thinks it's dead unless its charging?
HI,
CM7 requires most of the partitions to be formated with ext4.
I found this posting to be the most useful for my install of CM7:
http://forum.xda-developers.com/showthread.php?t=960542&page=16
a little dated, but very detailed!
Looks like /system /data and /cache should be ext4.
I would be surprised if running CWM from external SD, if it is setup correctly
would just crash before you try and access the internal memory though.
-> have you tried a second uSD card?
Could it be a bad card plus badly corrupted mixture of stuff on internal emmc?
You mention in post that device looks ok with USB power adapter connected?
Perhaps intermittent battery connector? (Try holding unit at different angles?)
Thump: whatever you feel comfortable with without doing any damage(?)
Good luck!

OK, morning report, left it plugged into the Nooks EOM charger cable over night, seems to be working this morning, its almost like the battery was dead...maybe i was using my Captivates charging cable instead of the Nook one? Anyways, everything seems to be better now, thanks for the help!

[Q] Formatted internal sd-card. Fix possible?

As the title suggests, I downloaded the app AParted by sylkat through Google Play in order to partition my EXTERNAL SD-card. However, in the hurry of doing this, I believe I have formatted the INTERNAL SD-card, which has resulted in a pretty much dead phone.
It does not respond to anything. I have tried all combinations, the hard-reset button, everything I can think of. My computer is no longer able to recognize it either.
I am then wondering if there is a way to recover the data in the internal SD-card, or just any fix?
Some info:
- My device is fully rooted with BL unlocked.
- I had installed iHackers 2.0 ROM on it
- I have backups made through TWRP-recovery
All help is highly appreciated. Thank you

So you can't get into recovery, fastboot, or flash modes?
What happens if you plug the device in to charge?
Unless you can get into recovery, it's unlikely that you'll be able to recovery anything. If you do manage to flash a bootable ROM onto the phone, you'll be writing onto the internal SD card and physical overwriting all your old data, removing the possibility of recovery.
If you can get into recovery, you may be able to connect USB, mount the internal SD partition, and then try running a file recovery tool on it. I don't know if the whole USB mounting bit will actually work, haven't tried that.
If you formatted the internal memory of your phone forget to try recover the data. It's close to impossible and for laboratory experienced only. Even if you try many files can be corrupted and it will not work anyway. I try many apps for classic HDD and they recover almost pictures and mp3 only, and if many files are in sub-folders this get more complicated.
If you have a backup of your entire system I will suggest to go back to Stock flashing original FTF then go through all the process to get again iHackers 2.0 ROM on your phone and when you can access to the TWRP recovery, restore your latest backup and you will have your phone back like it was before formatting.

I expected that. My main problem is that it does not do anything at all. If I had been able to connect it to my computer, I would have probably been able to fix it, but it does not connect to anything at all.
My only saviour would be a so-called "Jig", which boots the device into android through an SD-card, but I am not sure whether there exists one for Z1 or how to make one myself.
So is there any way of connecting or just giving the phone a breath of life through an SDcard-solution?
Probably only through the Update Service or Emma...

Considering the internal SD-card, which acts as the brain of the phone, is formatted. The "brain" has been removed, thus it does not know what to do when I push the buttons or plug it to the computer.

Well, it really depends on what exactly you formatted. If it was just sdcard0, most of the "brains" are still there. If you nuked everything that's physical on the internal SD, you're in worse trouble. But I don't know what you did.
You didn't include the recovery keypresses, but I'm guessing if you try to boot the phone normally (just pressing power button), you never get the vibration pulse when it turns on? If not, make sure to use the force-off button by the sim card (hold it for 10-15 seconds) to make sure the phone is off and not stuck on. If that still doesn't work, I think your best bet is to reach out to a service center.

Hmmm... that I am not sure of.
Exactly! no vibration nor LED light when I push the powerbutton. Imagine yourself pushing the button, yet it is as if you did not push it at all. I have tried the force-off button too, so my last and final solution seems to be the service center.
Thanks for your replies! HIghly appreciated

LED lights up for about 3 seconds before disappearing. However, from here nothing happens and it is dead as usual.
Any idea how to go further from here ?
From what I've read. That means the battery is completely dead.
I believe you need to leave your phone charging for a few hours/overnight and sometimes it will get recognised by flashtool

This is a good point, I didn't consider a dead battery scenario (though it makes a lot of sense versus the phone just doing nothing). I haven't actually read about cases where USB charging will bring back a super dead phone, but it's theoretically possible if the battery were removed and charged manually. That process, however, is definitely only for people who know what they're doing with potentially explosive battery chemistry. If nothing else, leave it plugged in for a while and see what happens.
I remember posting in another thread where someone killed their battery. The best preventative measure is to make sure you never get below 10% or so. The generally dispersed "knowledge" that taking the battery to 0% is good for calibration is NOT TRUE. These are Li-ion batteries, and deep discharges permanently reduce the battery capacity.

Great point, you two.. This reason seems quite probable too. However at the same time, it is WEIRD if the battery suddenly dies as a result of formatting the internal SDcard :l
Maaan, I had a slight hope, but I'll try charging it overnight.
Worst case scenario, the service center finds out I had rooted it and I have to pay for the service....

There's an entire thread dedicated to how people bricked their phones. Have a look there for some info
It all relates to flashing phones, but maybe what you done had some kinda of a similar effect
Do you remember how much charge you had left?
Supposedly the system loses calibration with the battery and and and and (Most of this relates to flashing though, so hopefully you just have a completely dead battery and an overnight charge will fix it back up.
I also don't think you lose warranty from having your phone rooted?
Think voiding warranty only applies if you unlocked your boot loader... - I could be wrong though.
Good Luck!

Actually I saw this behavior on deads Z1 thread, sorry to say, this actually is not a good sign.

Yes, I will suggest this too and when your phone apparently will be charged try just to push volume down and connect via usb to pc and see if it will be recognized. If he dose flash a stock FTF immediately.

Yea, I read through a few pages of that thread, but didn't feel it covered my case. I had a minimum of 89% of battery and it was charging. Hmm.. about the battery calibration, the day before this happened, I charged my phone to 100% and used Battery calibrator, which is an app in Play Store to calibrate it, so this shouldn't be a problem.. However, I suppose something has happened during the formatting.
I am quite certain one loses warranty when rooted or has unlocked BL.

Indeed, this seems to be my last way out of this. Either it comes back to life in the morning, or I am doomed! haha I have even prepared FLASHTOOL and the firmware, if the phone actually comes back to life and is recognized by the computer.
I will update you on this! You are a very helpful group of people. I am grateful for your help so far :good:

Woke up today and tested it. No sign of life at all so it is now sent to the service center..
Thank you for your help! You have helped me a lot

TWRP, eMMC errors, and a lot of questions...

So I have one great Note 4 that runs fine. A second Note 4, given to me appearing to be a paper weight, has been with some effort rescusitated. But no, the eMMC errors have not gone totally.
This "bad" phone, however, is allowing me to fully exercise some of my curiosity. And in the process, no matter what happens, I hope I can get a few more answers about things. I know about the little app that keeps the phone from going to sleep and stablizes it... that works on the phone unless it gets turned off. And then the whole cycle of trying to start it again (the freezer trick, the holding of buttons, the pulling of the battery... sigh).
My latest gambit has been to go into TWRP and reformat /system /data and /cache (the only directories where I'm allowed to do so) to f2fs. In fact, just to really wipe this baby as clean as I possibly could, I reformatted them back to ext4, then back again to f2fs. I then installed a custom rom (the official CM 14.1). It appears to have installed over the top of the f2fs without trouble.
But of course I am freewheeling it here. I do not know very much about what is going on down inside there.
My questions:
1. What "hidden" directories are there that TWRP isn't showing me? Is there any possibility that if I could reformat them (and not destroy the phone) it might help with the eMMC errors? How would I do that if I in fact can?
2. When I reformat the directories from one format to another, am I actually wiping them or not? (I've read long pages about people suggesting that Android phones are terribly hard to actually wipe all data off.)
3. Is there any other possible cause for the eMMC errors than bad physical memory? I understand that bad memory chip *is* one obvious cause... but are there other causes that could in fact kick up an eMMC error that isn't really about the memory chip?
I'll post any other questions if and when I think of them. Worst happens, I mess this phone up so bad it won't reboot at all. I'm not too worried about that.
All thoughts welcome. I can experiment without caring too much.
I have read elsewhere that the problem could be caused by having a micro sd inserted in the phone.

Yes, I've read that also. Tried all sorts of experiments with and without micro-sd card inserted. Using a Wake Lock app from playstore (set on mid-range) allows the phone to do and be nicely. But shut it off and I have to freeze it for 5 min before it will restart. So... hopefully the Chinese mb card I bought today will actually work. Providing I can in fact open the phone without busting it. (There's some good clues on youtube which is nice.)

emmc errors on note 4 is well known hardware failure , its time for you to replace emmc chip or system board

Yes, I said that in my first post. My point was that it is possible other causes for the error message just might exist. But all that is moot now... I did in fact order a new motherboard. But in the meantime, when I went to dissect the phone according to instructions on youtube, I found out too late that the author of said instructions was fairly clueless as far as a successful end result. The phone is dead, dead, dead. Lucky for me, it wasn't my main Note 4, which is just fine.
Here is a 100% hardware fix for this issue that anyone can do with no tools or specia

It really works. Give it a try. ?
