[Q] Blank Screen - What happened to my g2 ?! - Hero, G2 Touch Q&A, Help & Troubleshooting

Guys
My phone was modded -cyanogenmod rc1-. I used it for months and there was no problem until one day.Once I opened my phone it was just blank screen.Also there is no light on keys.Also I can't get into hboot or clockwork mode screen.I am not really good at these technical problems.But somehow I modded it What can be the problem if it is not a device problem? How can I fix it?
I have already searched for similar problems but I couldnt understand the detailed explanations.
Please explain for a newbie
Thanks for your help.

Take out your battery, plug it back in while holding Vol down + power and see will it get into HBoot

it was good to try something new but it didnt work.still just the backlight, nothing on the screen.

Then probably it's something wrong with the data itself, you probably installed some bad app that bootlooped your phone, your only option is to give some logcat to us or to reinstall the rom and start all over again, maby its time for an update, flash elelinux 2.3.7

Oops sorry but this post was ment to the guy that has a bootloop on elelinux 2.2, if you cant get into HBoot then either you hard bricked your phone or there is something wrong with your screen...

what can be the possible solution for hard bricked phone then : )

I dont think it's a hard brick since you would atleast get to HERO sign (i think) but if it is a hard brick then your only option is JTag..

no no i cant get anything.only black screen.i cant see anything and i cant access to recovery mods or hboot screen.

How do you know you are not getting into HBoot if your screen is lets say malfunctioning ? I think there is a better possibility for a screen failture then a hard brick, it's not easy to hard brick a phone, and it's inpossible if you were just using your phone on CM7, only way to brick it is a failed HBoot/Radio update... I'd get a new screen there, or it could be the motherboard that failed.

Bricked Hero

After ROM upload my HTC Hero show only some logo like device out of box. Nothing else is going. Button combinations for bootloader access is not working. Any ideas?
I managed to skilfully brick mine too, is a there a way to get it to boot up via key combination or using USB from a computer?
We are three now.
I know (presumably) my error: I flashed an SPL zip package that could be of the wrong type (Dream).
The boot shows the phone logo (mine says G2 T-Mobile).
The home keydown at boot doesn't work.
Is there a possibility to unbrick it?
Hope someone tells you how to unbrick it as I was about to do the update the ROM, not sure I want to do it now.
Right this is very weird as i had the same picture on my phone and thought it was bricked too..
BUT i just did a soft reset call menu end together. Then i did a hard reset as i wasnt sure if the soft one had done anything. Battery out then in and start up phone whilst holding down house and back key and then it started to boot up. So not sure if this helps anyone i doubt it as its very random but i thought id share just in case!!!
I had just flashed my radio when mine did this..
friend of mine had tha problem too, he had to send his device to htc.. 50 bucks ;-)
hmmm ... i am one of u guys now ...
no matter what key-combo i press, it just show a BOX and an arrow and a phone ... 3 sec later, phone turns off, no matter hwat key u press, it is not doing anything until u unplug the batery ... then when u turn it on, it repeat the same thing again
check if you can access fastboot via back+power when the phone is off. if so install recovery image and then install correct rom. if not i guess you're screwed, not sure though.

Please be more explicit as to what exactly you did.
(for someone to help you)

Bricked Vibrant, need help...

I have never bricked it before, and I cannot go into download mode... I tried the the Vol up and vol down, didn't work, so I have been using ADB and just ****ed something up....
Now I need to know a way how I can revert back to stock, please and thank you, I will forever owe you one.
EDIT: Okay there is some confusion, to simplify it I will take it step by step:
I replaced an APK file from my system/apps and ever since it has been force closing process.android.acore, so I tried reflashing to stock, it froze while doing so now I have a picture of a caution sign, a phone and a computer coming up on my Vibrant, it will not start up.
It is hardware locked because I have never been able to access download mode via hardware keys(I have always been using ADB).
Is there any way I can reinstall stock? Or is my vibrant now destroyed?
what exactly were you doing when your phone stopped working? "just ****ed something up" makes it hard to pinpoint problems...
I don't know I replaced my phone.apk with another one then ever since then it keeps saying process.android.acore has stopped working. It wouldn't stop showing up so I tried to reflash with Odin to stock but it froze and now it is bricked.
bumping a little bit, I have never bricked it before so I have 0 experience.
What do you mean by froze? On what screen? How far can you get into booting?

Alright let me start over with more detail:
I tried to replace the dialer so I replaced the phone.apk and then process.android.acore kept force closing so then I tried reflashing with stock, during that I don't know what happened but I think my phone froze, so then it shut off and turned back on, I only found a screen with a computer on it... I am assuming it is bricked.... I also know it is hardware locked because I tried going into debug mode with vol up and vol down, how can I unbrick it?
Try moving the stock rom into the phones internal memory via adb. And flash it after a wipe.
I am Also having this same problem
I Flashed my Vibrant through Rom Manager to Froyo 2.2 from eugene373 and sombionix.
After flashing to both ROMS for Froyo I wanted to revert back to 2.1.
I tried to put sombionix 1.3 eclair ROM back on to my phone using clockwork mod.
The flash was not successful it stopped in the middle but the phone came on with a Force close error of an android process.
I tried to reboot through adb reboot recovery with usb debugging enabled.
The phone shut down like it would reboot into recovery mode and now it gets stuck on boot at the samsung vibrant screen.
I tried to use ODIN to flash back to the stock Rom but the phone is recognized in ODIN but will not flash.
ODIN sees the phone but will not get past flash analysis. (Sat for 8 Hours)
I believe this is the definition of bricked. Please Help!!!!!

Can you get the phone in download mode?
Did you try this:
Pull battery
hold the volume up and down
reinsert the battery whiles still holding down the volume up n down
plug in usb cord
it should put you back in to DL mode
Open ODIN and unplug phone from PC and plug back in hopefully it will notice it then.
I am not sure if you can get in DL mode and it just wont let you do anything, but if you have already tried this my apologies.

Did you even read the OP? He is HARDWARE LOCKED ie BUTTONS DON'T WORK geeze people learn how to read!
And on topic, if you can't ADB and you are Hardware Locked, you are SOL. Try to get an exchange from T-Mobile since it appears that they regard being Hardware Locked as a defect.

Remove the back cover & remove the battery along with your sim & micro SD
Hold the VOL Up & VOL Down
(Keep holding those buttons) Now insert the battery

I'm hoping that you made a backup before you flashed the rom. If you did you should be able to boot into recovery and restore.
lol i think thats what i did. I backup everything using Titanium and rom manger on my sdcard. i just dont know how boot into recovery and restore. thanks for the reply

lol hmmm i wonder what males can do with that.....
i was thinking about doing that and see if i could pull a fast one on radioshack
You did a nand backup before flashing Megatron, right? If so, you should boot in recovery using Home + Vol Down + Power and restore it from there. If not, you have no alternative but flashing the rom again (or any other rom). Be sure to wipe everything from recovery before that.
If that fails, you should get the official rom for your location and flash it with kdz (there is a very well done guide here on XDA for doing that, search for it).
And consider flashing Void next time, is more stable and has the same features (and more) as Megatron (hwacc, jit, oc, stagefright etc).
In any case, if the phone boots, even if gets stuck on LG splash screen, it is not bricked. It can be re-flashed easily, just follow the steps in the guides.

press and hold down HOME + VOL DOWN while the phone is off, then turn it on, keeping that 2 buttons pressed until recovery appears.
But if you have used rom manager, this won't work. Your only chance to unbrick is this: http://forum.xda-developers.com/showthread.php?t=883314

The same happened to me when I flashed LOL rom. I was reading that it can sometimes take up to 5 minutes to reach the boot animation. My phone reached the boot animation in 6-7 minutes. How long did you wait before you removed the battery?
thats not working either. all i saw was a bunch of ppl with the same problem and eventually sent it to LG service

I was about to pull mine out too after 3-4 minutes. I was freaking out also but had to go to the washroom when this happened. When I came back, the phone booted. If I didn't use the washroom, I would have bricked my phone, lol.
A lot of people have this problem because on the Optimus One it takes forever to load the first time. My samsung vibrant was extremely quick, 1 minute max
as soon as u send to warranty, the faster u get ur usable phone back
or just use it as vibrator

You need to use odin to load a stock rom. You are not bricked, you are not on a bad situation, your phone will be fine once read about how to fix whatever you did. There are 9000+ threads on this same topic. I would tell you what to do here, but if you are not smart enough to google "how to unbrick vibrant" or simply read a few of the sticky threads ( those are the ones stuck at the top of each section ) I am not sure you are capable of following my instructions.
You need to odin jfd.
Beware of angry gingerbread man
Yeah what he said.. your kinda pathetic
I cant be completely useless though...
Open odin, try every method to get into dl mode or get recognized by odin.. youll get it eventually. If you don't know what to do after that, im sorry i even bothered to get you this far..

1) take your battery out
2) plug your phone a laptop/desktop
3) hold volume up and volume down + put the battery in
...should be in download mode...I am assuming u have a froyo bootloader...
If that don't work then on step three instead of holding both volume buttons only hold volume up..that works for GB bootloader...

Ok Ill point out why you got the responses (rude).
Things you didnt include in your post:
What ROM are you on. (Froyo could mean any number of ROMs)
What where you doing when it happened?
What have you tried already to fix it?
Where have you searched for the answer already?
The nature of your post suggests you are not an experienced user, thus you had no reason to be flashing ROMs. This is NOT a rude comment. Im simply trying to make your next post for help fluent. The general mantra of these forums is if you wont make the effort to research and try and fix it yourself, why should anyone else?
Remember:
What where you doing when it broke? >> What have you researched to fix it? >> What have you tried to do and its outcome?
Hope the best for you.

you are really not giving a lot of details here...all you are saying you tried installing a rom and then it froze halfway..
Are you rooted firstly?
If you are have you flashed CF-root kernel?
How did you try to install the rom?
More info and then more people can help you out buddy..see if you can get into recovery and restart your phone.
well... if you've tried "every" (its not like there are a lot) button combination... then just go buy a jig from ebay and force it into download mode...

Nothing from what you said would help..
He obviously flashed it with Odin, and he said he's getting a yellow triangle with a computer behind it..
From what I understood, he could get into download mode.
So just boot into download mode and flash stock ROM. That should do it.

anyone else seeing an increase in the "i bricked my phone" threads?
dont think its coincidence they are increasing after the american variants have been released. People need to check what model they have before flashing things.

its ok and same goes by my post as well buddy..we all been in his position one way or the other
1st - Your phone is not bricked if it show an image. Whatever image it is. The only real software way to brick your phone is to flash bad bootloader or stop a bootloader while they are being flashed. However, Bootloader are flashed first. So if your phone stoped half way, you should not have trouble too much.
Remove the battery from your phone for like a minute, then reboot your phone in download mode (vol- + home + power and when the phone light up, release power.) Then flash another rom from odin.
Also, what rom did you used ? If you flashed a rom for another phone, then you might have flashed bootloader for that phone on yours, which is bad. In this case you will surely need a JIG.
sorry im new to this whole rooting/flashing thing. i downloaded the lightning rom: http://forum.xda-developers.com/showthread.php?t=1095274
i have never rooted or doneanthing to my s2 before. all i did was follow the instructions on the page and thought it would be all good? it froze about a quarter of the way there in odin so i just took my phone out.
I usually find from this state I can get back to bootloader or download states
push and hold vol+ and home then power for bootloader
push and hold vol- and home then power for download
sometimes the phone can seem to freeze a little or even die (this happened to me loads on the galaxy s and once already on the s2) and removing battery sim etc or attaching the charger can jog it
however as other have said a JIG is your friend if for no other reason that even if you recover without it, custom roms up the rom count which some twitchy carriers might invalidate your warranty for, the jig will reset this
you can get them from ebay for less than £3 delivered, or there are instructions on this site for making them yourself if you are so inclined.
simply search 'galaxy s2 jig' on ebay mine was delivered today from portugal as I am way too lazy to make one and only wanted a counter reset anyway
