[Q] HTC Desire won't boot or charge

Hi! My first post here and, sadly, not a pleasant one for me.
Today I, while charging my rooted Desire (Ginger Villain 2.8, if that matters), launched an app and it crashed (black screen but with status bar still showing). Since none of the buttons were responding, I took out the battery and then put it back in and tried to boot it. I went as far as the GingerVillain logo screen but then stopped the process. Since I was impatient (and dumb...), I pulled the battery out again. On the next boot process it halted at the white HTC screen. But now on the 3rd try it refuses to boot at all. No response what so ever when I press the Power button. Charge LED doesn't light up if I connect the USB cable.
What could I have messed up? Any solutions? I sure hope I haven't bricked it or something... Any help is appreciated!

Can you access hboot or fastboot? If yes, use the last one flash ruu. If not, use the search. There is a thread with nearly the same problem like yours and when I remember correctly, it got solved.

Power + Volume down doesn't work.
The other thread that seemed to be about this problem also involved some physical damage. My phone hasn't been dropped or soaked though.
I will try to get a hold of a charged battery and see what happens. Don't know why would it crash and burn like this considering that I wasn't installing anything. :/

Also some people suggested a while ago, to take out the battery and leave the phone alone for a few minutes, then try to boot again.

Had it sitting for approx. 4h with the battery removed. Put it back in and still no response what so ever. Power button doesn't do anything nor does plugging in a charger. Wasn't able to put in a charged battery because no one I know has this phone.
Not happy about this. And I'm pretty sure the tech support will just end up blaming the root...

Well, try to hold down the power button for at least 30 seconds while the battery is off. It works with notebooks. Other than that, no idea.

i guess mobo is dead, with roor you loose your warranty as well, so if mobo is realy dead you need to buy new phone, or try look on Ebay, but first sent it to htc just for diagnostic, we need to know what realy happend to your phone and after that look for advice

eehh..no.... if the motherboard is dead - so is the root, they won't know, so you still have your warranty.
My phone also randomly died on me once, it was rooted and S-OFF'd, sent it to htc and they repaired it for me. Don't worry about it just send it off. If it's dead it's dead.

in that case you are right, if mobo is realy dead so the root is dead too, yeah
sent it to htc and you will see

Heh encouraging replies.
Anyway, I don't have an official subsidiary of HTC in my country so I'll just bring it to the shop I bought it from. Not sure if they do diagnostics and repairs themselves or just forward it to HTC.
Since I've never gave a phone for repairs, what are your suggestions regarding the SD card? I assume it's fine if I just remove it and bring in just the phone itself. Most of my apps are installed on the card, but I guess I can kiss them goodbye at this point, right?

no, all HTC as that you give them is your phone and your battery. No SIM card, no SD, no charger/ cables. Just the phone itself.

they dont need your sdcard, you should give them just phone, battery and thats all, everything else leave home, i just sent my phone with battery to repair, simple

Bumping this thread in case somebody finds it and wants to know the outcome. I gave the phone for repairs and the conclusion was a broken motherboard which they simply replaced.
I have to admit, I was ready to buy a new phone and now that I have my old one back, it's a kinda weird feeling. I definitely do want to upgrade to Galaxy S II but it's still bloody expensive. I guess I'll just wait till the end of my warranty (April next year) for even better phones to hit the market and upgrade then...

Black Screen of death wont turn on

I woke up yesterday and the Galaxy Nexus (GSM) was not responding well. The touch input was lagging and it appeared to be under load. The phone was not hot. I took the battery out and put it back in. The phone however did not come back on. I have left the battery out over night and then put the battery back in when i woke up. Nothing. I have left it pluggeed into the computer for 3 hours unplugged then put then battery in. nothing. I have done numerous battery pulls and nothing.
I have read every possible post I can find about this but haven't recovered my phone. It was running AOKP milestone 3 and kernal build 162 (can't remember name sorry). CPU was not changed from stock settings (governor i believe). It will plug into computer with nop battery in and give me the OMAP4440 device listing for a brief second so I know its not dead.
Any help would be appreciate.

can you boot into fastboot?
Holding volume up+down and power?

no. no fast boot response. ONLY thing that tells me phone is seudo alive is the USB recognition for 1.5 seconds when plugged into computer without battery. This happened to me once before and leaving the battery out overnight got it back. No luck this time. Bought phone May 4th. First incident may 5th. Didnt want to bother with return because I love the phone. Now out of 14 day return policy. Can't send to Samsung due to root/etc

yeah i tried that as well. i just said screw it today. called samsung got a shipping label. the warranty process could turn out bad/interesting. if it does i'll just let em keep the phone. been more problems since the day i got than any phone ive had. not flaming this gnex forum by any means so dont launch into a war on me. I miss my Galaxy S2. I work at an AT&T COR store maybe i'll poke around for when our GS3 is coming. I'll keep yall posted on what sammy says. If anyone reads this that has had a success story with recovering their phone from this problem let me know though please.

Sounds to me that your battery is flat and it doesn't charge. Do you have a spare one you can try (friend or work)?

My Gnex happen excetly same after I updated CMW touch zip by rom manager! No response on power button. Power + volume +- button! Garrrrrrr!

That 1.5 second you've mentioned when you connected to the computer... did it say? OMAP or something like that? If so, you have a good chance of "reviving" the phone. Search up for OMAP flash.

This excactly the thread you need
Good luck buddy

This post helped. My GSM GN suddenly went black in the middle of an installation. Tried the tip with battery . No go
Saw the same problem at iFixit forums.
The tip was same. The trick was to use the charger instead of the USB port.
Worked well and my GN is back again.

[Q] My Note 2 has died. Help?

My Note 2 has just died It was getting surprisingly laggy at odd moments in the past week, but I didn't think anything was wrong. I was updating a lot of applications one after another tonight (music was playing but it was jumpy, i think because apps were updating so i stopped music) and people were messaging me on the facebook app so I could see the notification light flash green. I was busy on my laptop, so I ignored the phone about 10 mins.
The green light kept flashing, but the screen wouldn't turn on when i pressed home or power key. so i took the battery out from the back and reinserted it. It wouldn't switch on at all, no SGS Note 2, no Samsung logo. nothing at all except a little red light flashing where the infrared light is everytime i tried to turn it on.
I tried connecting it to my computer. nothing happened. recovery mode bootup also failed. I tried charging the phone, even though the battery wasn't empty, still wouldn't switch on during charger plugged in or pulled out. Took out SD/Sim, no effect. A new battery didn't help. The phone doesn't charge either, the charger makes a funny electrical whining noise and the infrared red light flashes every so often.
It's basically dead. What can I do? The phone is also rooted, I can't remember how (think it's original chainfire root? i got my phone last oct). Will Samsung be able to switch on my phone and discover it's rooted? Also I read somewhere that legally speaking if rooting didn't cause the failure, you're still covered by EU law?
I am in the UK, bought Note 2 off a 3rd party reseller (Buymobilephones) who provided a handset, and T-Mobile for the contract.
Thanks

How long ago did you buy the phone?
If you were rooted, were you on stock rom?
If yes, than which build were you on, do you remember?
I have heard of phones dying from sds, were you on an older rom. If that is the case, and if you have hard bricked your phone, AND if you are under warranty you need not fear...the guys at samsung wouldn't be able to open your phone either to check whether its rooted or not, you are covered. Your phone would require a motherboard rwplacement 8n that case. I hope you had backups.

I bought it at end of last october, 1st gen/batch of Note 2s to hit the UK (IMEI starts with 354.....
I was rooted. The first auto-root Chainfire method via Odin.
Stock samsung rom. Very earliest versions of software.
I basically bought the phone last year when it first came out, rooted it as soon as possible and then did nothing else except enjoying my phone and install new apps. Whatever people were rooting/flashing/roms/kernels etc at the end of last october when the note 2 first came out in the uk is what I would have been on. Never updated since.
I might sound a bit stupid, but does a motherboard change means you lose everything in internal storage? ie photos, texts, contacts etc. I have no backups of anything. my fault I know. And Samsung wont' detect root after motherboard has been changed?
When you say "hardbricked", do you just mean it wont' physically and electrically turn on? Because i didn't interrupt rooting/flashing etc.
I googled SDS for the Note 2. Seems there is an issue I can't think how else my phone would just die.

I think we know the cause now, its sds. Only roms and kernels which have been developed after January 2013 are free of this problem. As you had rooted very early you would not have recieved stock updates from samsung. And as you had not flashed anything new, the rom/kernel you used had the sds problem. Had you recieved stock updates or had you flashed any latest rom your device would most probably be working.
Now the good news is, as I said, samsung has no way of learning whether your phone was rooted or not. A soft brick is when your phone is in a bootloop. A hardbrick means it wont't turn on, won't do anything at all. Your phone is hardbricked in a way. So a samsung engineer would be as powerless to turn your phone on in this condition as you are. And thus, you would be under warranty.
The bad news is, yes, all the data on your internal storage is gone. The phone you would be provided would be a new factory reset model altogether. That is of course, if the problem is sds, as it seems right now. Even if the problem is different, something smaller, a factory reset is what you will get in all probability, so no chance of saving the data.
I am really sorry for your data, and I know it doesn't help when I play Captain Hindsight, but you should have made a titanium and nandroid backup at the very least. Do that for your next phone regularly. It is the most useful aspect of rooting your phone if you ask me.
Of course, I could be wrong here. The problem could be something smaller. I suggest you throw this problem @dr.ketan on this thread

Bricked Cubot X15... seeking fix (?)

Hi all,
I bought a Cubot X15 as a gift for my wife. She used it for a few days without a SIM card (just WiFi) and when we put a SIM card on it the phone thought it was stolen (?) and asked for a pin code we never set up.
I googled around and seemed to me that the only way to unlock it was to flash a new ROM, so I downloaded a ROM I thought it was correct, flashed it following the instructions and the phone seems dead.
The only glimpse of life is when a cable is when the laptop is connected to the phone and I press "down" and "power", the laptop makes the noise that USB is connected and then, around 5 seconds later, sound of USB disconnection... other than that NOTHING.
No other combination of "up", "down" and "power" does anything, no Chinese characters, no noise, no screen... absolutely nothing. And I am 100% sure the battery is almost full.
I would like:
1) Confirmation (as best as you can, with the information given) if I need to get a new phone or
2) Help to resuscitate the Cubot... in fact, I would prefer if I can ship the phone to somewhere in Australia and someone fix it for me (willing to pay if successful).
Thanks in advance

i need answer too, i have the exactly same problem... :crying:

CM 13 SIM Card Issue

Hi, I installed the 8/20 CM 13 release on my S4 using CWM and it will (about 2-3 times a day) not recognize my sim card and tell me to restart. When it does recognize it, everything works well. To get it to recognize it again, I have to power off, pull the sim, power on, then power off again, and restart with the sim in. I searched and read that changing the modem/radio (modem.bin) drivers will usually fix it. Can someone please point me to the correct drivers and install instructions?

Does the phone do the same thing when running the latest stock ROM? If it does, there could be a problem with the sim card reader.

No, it doesn't. I thought it was the reader first and replaced it anyway.

This tells me it's a software perform. The phone is running the latest bootloader and modem?

No. That's what I need to know how to update. I loaded CM 13 and that's it. I didn't change the bootloader or modem. Honestly I don't know what a bootloader is.
I have baseband version M919UVUFOK3

If you flashed the latest stock ROM from sammobile.com, the phone would have the latest bootloader and modem installed.
A bootloader is similar to the BIOS of a desktop or laptop computer.

So was i supposed to flash the latest stock rom before installing a custom ROM?

I suggested flashing the latest stock ROM because that is the easiest way to ensure the phone's modem and bootloader are up to date and should be done just before you start flashing custom ROMs. It doesn't have to be done every time you want to flash a custom ROM.

Same here..

Apparently this is a common hardware issue with S4, something to do with the battery fluctuating voltage to the sim card reader, I recently found out from a repair shop, whose only solution was to downgrade to stock. Heck no, I got Nouget and ain't turning back! Mine doesn't ever have an issue while it is charging. I flashed over a dozen different roms, tried using a few different modems (even stock), read somewhere that you can press a thin cardboard against the back of the sim card against the holder, that didn't work, tried to blow air into the holder, didn't work either, used different bootloaders, nope, preyed to god that I would not miss a call while I slept, nada, don't rely on wake up calls! Tried a new battery, that might have worked for abt a week.. but the dreaded "SIm card removed" message returned!! So I had some drinks and it got some too.. and I watched it get thrown at me and skip off a table, felt it burn up in the summers, in my pocket on many occasions, this phone has been through many adventures in the past couple years and still works great, never even cracked the screen! < knock on wood > This phone can take a beating, compared to many other phones I've had. Other than the fact the reception isn't amazing, I really love my S4 model 919, its fast, compact enough, great display, good bat life, but like every phone it has it flaws. I'm sure that they wouldn't purposely f with their phones so once its modded it gives you an annoying random bug that would make you want to buy a newer S.
The question is how long you can endure the pain of rebooting every few hours, so why not upgrade??
Samsung want you to UPGRADE TO NEW IMPROVED S5,S6,S7,S80..!!
UPGRADE OR NEVER LEAVE AC OUTLET!!! hahaha
.. Personally, I probably will buy a S7 soon as it drops price ( I have a really active life) but for now I just deal with it.
>>> I'm more worried about when someone is gonna fix the video camera for Nouget !! Big up to ResurrectionRemix and XDA!! <<<
ps.. I don't ever remove the sim card, just a full reboot is all mine needs. GL

Same issue here..
Just a thing I observe. When my sim card shows is disconnected or sometimes after reboot is even showing that my sim card is not inserted, I cannot turn on my mobile data and the sim card app is missing from app drawer and from application manager.
I really don't know if its a software or hardware issue.
Sometimes I get this error randomly, even when my phone is standing still on a table and I don't use it.

Thanks for the replies. So, I got a new SIM card and it seems to be working much better than before. My old SIM had a huge scratch on it, so I suspect part of the issue might have been that. I've also kept it in balanced power mode, and I noticed it happens more in battery saving mode. I've also been trying to keep it plugged in as much as possible, and I have extra charged batteries I swap in. It will also start working after a reboot and I don't have to pull the battery and card like I described before. I still haven't tried to change the boot loader or modem.
Edit: I'm also having an issue with not being able to download MMS unless I'm on WiFi

Are the apn settings correctly entered?

This is a known issue (not CM related); contact your carrier for a replacement.
Sent from my SGH-M919 using XDA-Developers Legacy app

Just an update: I'm still having this issue, but have just been living with it and trying to keep the phone charged. It seems to happen less on WiFi and when I'm actively using cellular data. Some apps seem to make it worse. I'm probably going to try a different release.
