[Q] Problems since installing CM7 on HTC Merge - Android Q&A, Help & Troubleshooting

The first time I've allowed my battery to get very low since installing CM7 on my HTC Merge and I'm now having all sorts of problems.
Firstly my screen won't light up. It's just completely black. The phone is on and the 4 buttons at the bottom light up but that's all. The phone is still responding to my touch as I can load apps and hear noises if I happen to touch the correct parts of the screen. It's almost as if the brightness has been turned way down, but I'm unable to see the controls to try turning it up again. I have tried booting to recovery mode but that doesn't display either.
Secondly the battery won't charge. Since the battery is drained I can only get the phone on when it is plugged in, but the orange "charging" led at the top of the phone never lights up. It just casually flashes like it ordinarily would have done when it was running from the battery. I have two batteries and they're both doing this.
I can't be 100% sure that these problems are due to the installation of CM7 but I've never experienced it before so i'm guessing they're connected.
Does anybody have any suggestions on how I can get my phone working again.

It's also worth mentioning that it is also no longer recognised by my computer

Sounds like a hardware fault, if you have the same issues in recovery as you do in your os then its very unlikely its ROM/software related
I don't your device nor have I taken it apart so its only guesses I could give you on which component needs to be replaced, LCD or flex cable are best guesses

Want to update on this as I've just had another look at it after a while.
With the battery having completely drained, I connected the phone to charge via my PC and the orange charge light lit up and the phone went into recovery mode without any assistance from me. After about 2 seconds the screen went off again.
When the battery has charged sufficiently, I am once again able to turn the phone on and it boots up... but the screen remains blank.
If I discharge the battery and then plug it into my PC, I am able to repeat the appearance of the recovery screen, but it always vanishes before I am able to do anything.
The screen must be surely be functional or how would I get those 2 seconds of display ?
Does anybody have any ideas of what I can do to get the phone working again?

I acquired a new battery and after fitting it the phone immediately worked again. The battery was completely without charge but the phone charged it up without any problems. However, as soon as the power ran low the same thing happened; the screen has stopped working and the battery doesn't seem to charge anymore.

MTP-initialization.

Got some strange bug. In the notification "menu" it often say "mtp-initialization" even though i havent connected a usb to the phone, also it sometimes think im charging the phone and it gives me the charging animation even though i aint charging it. Why is that? It doesnt matter what rom i use the problem is always there.
Another problem i have is when i turn off the phone it shows me the green battery image plus a thermometer that shows me it is overheated or something.. its always there when i turn it off and to turn it on again i have to go to the recovery and reboot it from there to make it boot up. Why?
Sent from my GT-I9100 using xda premium
me too and it's really really annoying!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! it does that every 10 secs or so!!!!!!!
I have the same issue. The common denominator is it all starts after I have charged the phone. The MTP tries to initialize even though my usb is disconnected.
When I shut the phone down, it reboots after a few minutes with MTP trying to connect.
When I pull the battery and reinstall, I get a grey battery charging icon followed by a green icon followed by a battery icon with a warning triangle and a thermometer.
Same here. Any solutions yet?
I'm having issues with MTP and my Galaxy Tab 10.1, it says MTP connected after MTP initialisation but the Tab never shows up in Windows and Kies??
Same problem here, with unrooted i9100.
I think it has something to do with the usb port. I've red somewhere that the quality is very bad and that it is very vonurable to dust.
This is sooooo annoying i just want to put music on my phone and the only way to do it is take out my external sd card and put it on.
Had this issue also recently when I watched videos for longer than usual (Only around 40 minutes). Car mode started going crazy and the device wouldn't stay powered down. I then removed the battery for a couple of hours while I was busy and when I put it in again I got the green battery image that the OP described. From my searching this seems to be a problem based around the usb port and its connector. I tried doing what others suggested in similar threads and move the metal pin up slightly but this hasn't helped.
I'll be running the device heavily again tomorrow (Video wise) so if it acts up again I'm calling samsung for a replacement/repair. This is a really ****ty problem and stranded me in the rain as I couldn't even get the device to boot for 20 minutes due to the battery image problem. I also doubt it's a problem with the battery as I replaced my Anker 1900ma battery with the stock one and the problem persisted.
Wouldn't you be able to get it fixed under warranty, expecting of course that you restock back to original state....
Sounds like a hardware fault which would definately go under warranty...

[Q] Rezound wont charge a dead battery

So the past two nights iv let my rezound battery go dead. The problem is it wont charge a dead battery. It charges if there is some battery and its on but when it is dead it is dead. The fix was I had to put the rezound battery in my tbolt to get a little bit of juice.
Any ideas or similar problems? I am unlocked with the htc unlock tool and running nils business sense?
Could it be a rom bug?
Don't let your battery die. It's bad for it anyway.

Once the battery is dead what does the LED on the phone do? If it blinks for a while it is either too hot or too dead to turn on, but it can still charge eventually. If the LED is not coming on at all I would pull the battery out and connect the charger with no battery and see if the LED comes on. If still no luck, get a new charger.
Blinks then Charges
I had the battery die on me once (on a prior battery and prior rezound). The phone will blink orange for a WHILE (I tried 3 different chargers not knowing what it was), but eventually started to charging. I think patience is needed. If, after 15 minutes, you still aren't charging, then that's something (but longer if the phone was also hot).
If I hit he power button with or without the battery in the led will light for a short time. I had it plugged in all night and no charge. I used two different plugs.
As for not letting it die. I know its not ideal but I couldn't help it.

+1. Same thing here.
KORM via the beast known as the Rezound.
I let my phone die completely once. I freaked out that my phone wasn't charging. I went onto HTC's site and it said that it could take 20 or more for the led to turn on while charging if the phone was completely dead. Just plug it in and be patient. It will charge and the led will eventually turn on.

I had this problem too, and am a little concerned I have a defective phone
So I had this issue happen this weekend. My daughter was using the phone when it died. Couldn't get it restarted. (I am unlocked via HTC, stock ROM with bloat removed. Phone is a week old.)
After messing with it using the factory charger/cable and other chargers/cable combinations I got nothing. Light would only intermittently come on for a second or two then go back off.
I charged it over night with the factory charger/cable. Didn't work the next day. Charged it all day and night with my old charger/cable that I know works. Didn't work.
Tried multiple variations of taking out the Battery/Sim/SD card and using the plug-in chargers & CPU USB variations with no success.
Luckily, I had ordered a new spare battery and it came in the mail before I returned the phone. Plugged it and it started up fine.
But my concern is that my phone is not properly charging. I have also had other similar charging/battery life issues that raise concern.
As far as not letting it die, **** happens and phones die, if this is a reoccurring problem, that in my mind is pretty unacceptable. A phone should charge when its plugged in no matter what. I may end up returning it to see If just got a defective phone/battery.
My phone will turn on then off and im starting to think it has something to do with the battery. But when it started it was in tue yelllow on the status bar, now i have it charging without being turned on and the indicator light is on but hopping mine will fire up soon. This all just happened to me within the last two hours lol, already called verizon to get a replacement but still going down there tomorrow.

--I agree, but once it gets down to 5%, why not just turn it off knowing the problems people are having so wide spread now.
Under the exact same conditions I have had the same problem with a warm battery reboot. It seems to occur when you are talking on the phone and let it die. Once it dies the phone will not reboot. My wife has the exact same phone. When I put her battery in my phone the phone works fine. My wife’s phone dies every night and she simply plugs it in the wall and it charges no problem. Again the conditions seem to be related to the battery dying while it is hot. If the battery dies while the phone is cool and not used then it seems to reboot no problem. I will go to Verizon tomorrow to look for a fix. I will let you know what happens.
I'm also having this problem but i can return my phone because i unlock it or can i return it ?
Check and see if your battery is 3.7 or 3.8v . I wonder if it is related to the charging issue with the 3.8v battery some people seem to be having.

it's a 3.8v what do you recommend i do ?
I had this happen, and here is what worked:
Unplug charger
remove battery
plug charger in
insert battery (while charger is plugged in)
I got an immediate orange LED and after a little while I was able to run the phone back on.

I had the same issue with my OG Droid. Would kill the battery and it would stay dead, even after a whole night of charging. The above method seemed to work for me.
I make 100% sure mine never goes totally dead after an experience I had with my Droid Charge.
I accidentally let it die completely (I fell asleep when it was almost dead & it ran all night). The next morning it was off, I put in a fully charged battery & it fired right up but started FCing like crazy. Every single thing I clicked on force closed immediately, I had never seen anything like it.
I was running a custom ROM & kernel & had done a nandroid BU the day before. I restored the BU & the phone ran perfectly again, but that scared me enough that I made darn sure it never happened again LOL........

That didn't work for me i just won't let it run down i guess.
Holy ****!!! I think I may have found the fix! I have had the same exact problem as everyone in here. It seems to happen once I root. My Rezound would die completely, then after plugging it in, the light would come on for 5 seconds or less then shut off. I plugged it into my computer and Windows makes the USB Connected sound, so I figured something is happening.
I went into my command prompt and *adb devices*. It showed my device, but says in recovery mode. I then *adb reboot bootloader* and the bastard rebooted into bootloader! From there, I chose "REBOOT" and it fired right back up! Anyone who is having this problem, please try this and let me know if it works for you!
***UPDATE***
It appears when the battery dies all the way and then doesn't charge, the phone is automatically going into recovery mode even though nothing shows on the screen. I had my SIM card out when I tried this the first time, then when putting my SIM back in, it started doing the same thing. But again, it was going directly into recovery mode. This time, I tried a simple *adb reboot* and BAM! I'm back up and running! Again, let me know if this works for you, or if you need help doing this, let me know.

Yes... HTC phones never charge "powered off" When you turn it off and then put it on the charger, it is actually entering/booting a special screen off recovery mode during charging.
CWM recovery on the rezound has trouble charging a completely dead battery.
Use Amon RA recovery.

[Q] Dead battery = boot to recovery with no video

This is something odd I haven't experienced with any Android device until now.
Whenever my Rezound battery is depleted to the point where the phone shuts down, I cannot get the device to boot back up again without ADB.
While it's powered off in this state and plugged into charger, it exhibits no charge LED or any other type of activity.
After pressing the power button, it appears to do nothing whatsoever.
If plugged into my laptop USB, the OS detects the device and loads the Debug mode drivers. ADB DEVICES shows the device as being in Recovery, and the device is still completely dark, no video, no backlight, no button lights.
At this point I can ADB SHELL and issue commands, but it can take up to a dozen REBOOT commands (although sometimes on the first or second try) to get the device to do anything other than reboot directly back to dark-screen recovery. I just keep running REBOOT until finally the white/green HTC image appears and the phone boots normally as if nothing was wrong.
Once booted, it behaves perfectly for as long as the battery doesn't die. I can reboot, HBOOT, power off and on, do a Clockwork backup... But, if i let the battery die, I have to ADB REBOOT until it decides to come back to life.
What do you think. Hardware or software issue? Try RUU?
Thanks!
there's definietley a huge problem wtih this phone. i had a guy bring in a phone that died overnight and the same thing happend...he'd plug it into the wall, for 5 seconds it would show orange charging LED, then just shut off..phone wouldn't power on, either. he had it plugged in charging for 3 hours though, and the phone was still dead.
when i switched batteries, teh phone would not go past the white HTC screen. it was just dead. we had to get him a replacement. i'm seriously afraid to shut off my phone now or even let it die. sigh.
Oh yea, mine does the not booting past white HTC screen occasionally between REBOOTs as well. I am disappointed with HTC now, my original AMOLED Incredible was totally rock solid for the 2 years I carried it along 40+ airplane rides to 11 different states. This Rezound craps the bed if you give it a dirty look
Everyone should take a look at this thread in the Vivid forum. People were havin problems with their phone booting into CWM when the battery was dead, me included. Our CWM was updated to support charging and now all is fine. Might be worth looking into.

[Q] SGH-i777 - From Shoebox to Brick

Hey Folks,
I have a Samsung Galaxy SII (SGH-i777) that I used a couple of years ago. It was my first Android phone and I loved it very much (until corporate made me an iSheep).
The phone was retired to a shoe box for the last 1+ years and I recently dug it up so I could get it set up for my little bro who somehow recently fell on his phone with it in his pocket and shattered the screen (don't ask... I don't get it either).
Anyways long story short -- the phone sat idle for a long time, when I pulled it out it wouldn't boot up at all. Assumed that the battery had discharged so I plugged it in to see if it would start up. The battery logo would intermittently flash on the screen and show a drained battery logo but even letting the phone sit for a day did not provide me any results.
Fast forward 3-6 months. Today I replaced the charging board thinking that there was some issue with the USB connector on the phone that was preventing it from getting power. Once that was done I discovered that I was able to get the phone to boot into Odin mode. Great! No boot, no recovery, but download mode seemed to be better than nothing.
I have tried, in vain, to flash stock firmware to this phone via Odin, and even though all indicators point to it being successful, once I finish the Samsung logo comes up on the screen, goes off and that's it. I can see the 4 LEDs on the buttons at the bottom of the phone flash every 5 seconds as well as a faint flicker on the screen staggered between the LED flashes.
Looking for any further suggestions as to what I may be able to try. I have searched various sources on XDA and other sources but I haven't quite found anything that matches my exact symptoms.
Furthermore, I can't be sure what Kernel/ROM I was last running on this phone. Maybe Siyah kernel, maybe CM 10,1 with Flux kernel. Idk.
Any input is appreciated!
Seems I should mention this other detail --
With the battery in, I cannot get into download mode -- it just states 'Low Battery!! Can't Download!!" This is presumably due to the fact that the battery is completely discharged -- maybe incapable of holding a charge but perhaps this is indicative of a more serious hardware failure.
I'd guess the battery is completely shot.
I bought a replacement battery from here: http://www.ebay.com/itm/111014533334?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649
No problems with it.

Very likely --
Since you got me to shift focus here, a quick search is telling me that it won't boot without a battery due to a feedback circuit. This would explain the ability to go into download mode but the lack of boot / flashing LEDs I guess.
Can someone confirm?
If the phone was working normally when it was put away, I would expect it to be working normally when it was pulled it back out. Your story is a little confusing, but did you ever try booting the phone with a fully charged battery? In the circumstances you describe, that would be the first logical trouble shooting step. And if you haven't tried that, then it is still the next logical trouble shooting step. Also, you can't assume that the original battery that you left in the phone is still able to hold a charge. It still may be good, but you can't assume that for testing purposes. Incidentally, the battery should have been pulled from the phone before it was put away.
I do not get any indication that the original battery is actually charging. Charging icon just flashes on the screen briefly in between LED and screen flashes (again, presumably due to the battery being completely dead/incapable of holding a charge since I left it in the phone this entire time).
I guess I'll go ahead and buy another battery and see what happens.
It is my understanding then that this phone will not boot on the charger without battery due to a feedback circuit. Correct?

Even if the battery is good, but fully discharged, it may not charge in the phone. You would have to have an external charger. Phones are not consistent, and many phones probably would charge a fully discharged battery, but I have seen a number of people report that a fully discharged battery would cause the exact same behavior as you report. If it were mine, I wouldn't throw the battery away yet.
If you know anyone with an I777, you could borrow their fully charged battery for a few minutes just to see if your phone will boot.
You are correct that the phone will not boot on the charger when the battery is out, although you should be able to successfully flash firmware through Odin with the battery out, and the computer supplying the power, but still, as far as I know, it will not boot after the flash without a working battery.
The battery was indeed at fault. Ordered a new one on Amazon, popped it in and voila -- we're up and running.
Thanks for the input guys! Much appreciated!

Is my phone dead?

Phone has been running fine for months, then all of a sudden, it won't boot. Wife said she hasn't dropped it or anything. It is an SCH-i545 with the latest PhoenixROM.
When I turn it on, it briefly shows 'Samsung Galaxy S4', then that disappears and left with a blank black screen from which I can't reboot or shut off without taking out the battery. If I try download mode, I get the warning screen but it goes black before I can hit VolUp to continue. If i try recovery, I see the blue recovery starting text but then the screen goes black. Also, if I plug in the charging cable with battery out, then insert the battery, it won't turn on.
My phone did this. All efforts to get it to boot were futile. Samsung, and then dark. And then just never booted again. Even trying to charge it, the charging screen never showed. Not a vibrate or anything, I even shined a flashlight on the LCD to see if maybe the backlight just died, and again nothing. That was 4 months ago, and today for ****s and giggles I plugged it into my Anker battery to charge and the charging screen came up!!!!! I let it fully charge and then booted the phone and it works again!!!!
Now I just have to fix the screwup I did a long time ago with the radio, I did the "Golden Backup" improperly and my radio quit working on CDMA altogether. No documentation to be found, even Samsung upper tier support has no idea how to resolve it or even what the hell I'm talking about. I'm guessing there is no support but maybe flashing a modem will resolve it.

Same radio issue, I get no signal on the phone, just a circle with a diagonal line inside
This is sick
If you can get it to boot into fastboot, just reflash the full OEM rom which should include the modem image
