[Q]My phone will not start. Just a black screen.

So I recently rooted my phone with this tutorial:
http://www.youtube.com/watch?v=nkkcCCjeUpI
Everything went great and I was rooted. So next I decided I wanted to flash a rom. So I decided this one:
http://forum.xda-developers.com/showthread.php?t=1817345
I looked over it and followed its instructions. So I flashed it. I also flashed the google apps.
This is where the problems started. I rebooted my phone, and It never would show the boot logo. I kept pulling the battery and it would not start. I thought the battery might be dead so I charged it, and still nothing. I noticed when I plug it into my computer and it makes the little connection noise. (Like my computer is reconising the device) But still nothing on the screen. I tried to connect it to odin and it does not show the device.
So I have looked all over the internet (including these forums) and have found no help. Sounds like I might have bricked my device.
So my last question, If I did indeed brick my device will this fix it? (I mean will it atleast get it into download mode?)

Please let me know if you have any ideas.
Thanks, Griffsbrown

Boot into recovery and restore the nandroid you made before you flashed.

Man sure sounds like most the people having problems are cause they are rooted/modded. Hope its a simple fix for you. GL.

You flashed a rom for a different phone, its dead pretty much. research jtag I read its about 60-100$ read more in the future.

You flashed a ROM for a different phone. That is why you can not boot. Are you able to get into download mode? from the power off state, press and hold the volume down and home bottons and the power button. This should bring you into download mode. IF you can get there then you should be able to recover.

always be careful when flashing roms if you can get into download mode like the above poster said then your lucky and can odin a root66 and you will be back to before you installed the wrong ROM.
If you cant ........... your bricked my friend time to learn a lot more about jtag (which is a lot more difficult than odin READ READ READ
The only thing is people have been installing ATT roms for some reason their phones are not bricking but unless the dev says it works i wont try it.
ONLY USE ROMS FOR YOUR PHONE im really new and one of the first things to know.

Bricked! Search for mobile tech videos jtag fix.

[Q] Samsung t989 Galaxy S II - Bootloop HELP please :(

I downloaded the Jedi Mind Trick JB 2 ROM and installed it via clocwork mod recovery .. That went fine but it took me a few days to realize I didnt have a working video camera anymore on my phone.. so I thought to flash a stock ROOTed rom instead...
Then I found this threat about an updated version of Jedi Mind Trick's ROM labled JB 3.. So I wiped as much as I could in recovery and chose to format all the options it gave me in recover , Format system , data , cache , emms(or something) .. and now when I boot the phone , it shows the first flash screen , and the samsung logo starts to shimmer then it reboots back to the splash screen and repeats this process everal times before just going black and sitting there..
So I've successfully bootlooped my phone doing this..
MY PROBLEM -- I don't know how to charge my phone or connect to it to install anything else..
Is this a serious problem? How can I charge my phone to continue troubleshooting it? It still has some battery to try some things but I don't know how to hook it up to transfer any other roms to it via USB cable and PC in it's current state..
I'm very computer savvy but I'm trying to learn this phone modding stuff and I realy hope I didn't brick my phone in this process.
Can someone please help me out here? I'll be on the forums religiously until I figure this out.
What should I start doing first??
Any help would be greatly appreciated!! Thanks!

still working at it
I think I'm at the point of having to use ODIN to flash a new rom since i cannot simply copy this rom to the sdcard to use clockwork to flash it .. Am I correct on this ?
For some reason this rom I found (should be stock rooted tmobile gSII rom) does not want to open from ODIN's PDA button cause its in .zip and not .tar or anything... I'm not sure how to flash this rom with ODIN ( I'm not even 100% sure this is how its supposed to go) Any suggestions ?

phew
UPDATE - So I managed to research enough to find out that there is no way to flash a CUSTOM rom with ODIN.. SO I had to download a stock (presumably rooted) t-mobile rom and flash THAT ...
Now I'm back up with a rooted rom and will begin re-installing clockwork and then my custom deodexed rooted rom afterward.
Thanks for all who almost kinda tried to care to reply in this past 2 hours =) -- As previously mentioned.. I am a nerd.. I just suck at phone modding. Haha
So , looks like I'm in the clear now and don't need any more support on this particular topic yet.

Is this true? Through a recommendation (haven't done anything to my phone from rooting/flashing KANGSJUGGERNAUT2 years ago), I tried to flash CM10 and ended up with a bootloop myself. Tried flashing through ODIN but it kept crashing; does anyone know why?
Afterward, I tried to reflash it through CWM and from then on bootloops into a installation process that never completes.
For some reason my CWM turned super slow, freezes/hangs and reboots after a few minutes.
I gave the phone to a friend who does this stuff on the regular but he said my initial flash wasn't complete cause in download mode says I'm still running official? No clue.
I was told this via email/chat: "No luck, it won't even boot anymore, I think I'll just bring it back tmrw morn
10:43 PM
Sorry I'm at a wedding (yea I know random) I left my phone with coat check
OK I've narrowed down the reason but not the solution, you had an AOKP based ROM which fundamentally is based on CyanogenMod, but it wasn't correctly flashed as the phone still thought it has factory ROMs still running
11:10 PM
Clockworkmod(even though it was working before) wasn't accessing the partitions of the phone correctly so it wasn't properly wiping or flashing properly.
11:12 PM
So basically from the first time you flashed cwm it didn't flash properly then the next time you flashed using the new recovery it didn't flash anything it was supposed to do itself properly , so basically it was a chain of events in addition to a bad boot loader, that's why it never went to recovery or download mode correctly
11:13 PM
That's something that had to do with the way the phone was built meaning you may of had a bad bootloader from the very begin and are now feeling the synptoms
Basically, and I would hate to be the reason or partially the reason you have a dead phone, basically it was a matter of coincedencr that it happened as this could of happened at anytime, once you have a bad boot loader its pretty much down hill from there"
Any helpful insight as how I can rectify this? is my phone truly dead? Sorry about the quoted format, it was copied and pasted.

If I were in your boat, I'd use Odin and flash the stock 4.1.2 ROM.

The phone won't turn on, unable to go into recovery and download mode; plugged in usb (hear connection beep but pressing power button plays disconnect button) to no avail. What can I do to unbrick?
Stock 4.1.2? Possible over a hardbricked T989 with old 2.3.6?

sorry but i have to assume that you are not doing the 3 button recovery or download mode right.
Pull battery, put battery back in, hold power button & Vol +/- untill you see SAMSUNG on the screen ---> let go off power button(keep holding
Vol +/- button) .....u will see recovery. (assuming you did flash cwm before).
Let me know.
hit thanks.

I believe I am doing it correct, I have been entering recovery and download mode many times, right before I soft bricked it.
And sorry, no, I've tried many times, many methods and my phone is confirmed as entirely hard bricked.
SUPAR SAD, but thank you!

you can try using adb and put the phone in dl mode.
sometimes its as easy as pull battery and wait awhile (20 min or more) and try again.
if you've exhausted all possibilities, you can use a jig to force a dl mode.

I don't know what adb is, or how to use it; I have, however seen my friend RDP to my desktop and do something and used the term 'adb' in his attempt to code through the phone.
I've done that battery waiting period, for nearly an hour and still no result.
After doing some researching, I have found that many people have stated a USB JIG would not be applicable to a 'hard bricked' phone. I really wanted to try as it looked like the most, simple and inexpensive solution.

[Q] Where did I go wrong?

Hello I want to start by saying I know the phone is hard bricked and Jtag or warranty is the only solution. I have an AT&T S3 with root and goomanager on it running the stock ROM. I ordered an S4 and thought I might play with some other ROMs on the S3 until the S4 arrives so in goomanager I had it install the latest recovery and when it was done I told it to reboot into recovery to familiarize myself with how TWRP worked. However the phone shut down and never rebooted so I tried to power on and got nothing removed the battery for a minute and tried again still nothing plugged into the charger nothing plugged into the computer and got QHSUSB_DLOAD driver not found. I did some reading and came to the realization that the phone is bricked. I am ok with it because I am still under warranty for about another month and as I said I have an S4 that should be here on Monday but I would really like to know what went wrong as to avoid it in the future. Any suggestions will be greatly appreciated. Thank you in advance.

Goo Manager can be a real nightmare for some people. If you have a d2att and flashed a d2att recovery you've done nothing wrong really. I only update my twrp when the .zip gets added to here to avoid using Goo.Manager at all.
Have you tried booting into recovery? Volume up + power + home?
I also know a tip that works well for booting into download is pulling the battery plugging in the usb and doing the botton combo Volume down + power + home and inserting the battery.
Maybe you'll get lucky.

Thank you for the reply I did as you suggested and a red light comes on until I put the battery back in then it does nothing. I did get ahold of AT&T and they have sent out a replacement phone at no charge and it should be here Tuesday. I thought Goo Manager was the newest bulletproof rom manager out I use it with my S2 and have never had an issue so I thought it had to be something I did. Thanks again and Ill be more careful of how I install TWRP or should I be using Clockwork with this phone?

[Q] I need help. My s3 i747M shows zero signs of life.

So I wanted to install a new custom ROM and I all ready had one. It wasn't the first time. So, like usual I download the files needed and put them on my phone, boot into recovery and flash them ( but I didn't factory reset or anything because with the ROM I had I didn't need to for it to work I could just fix the not responding errors) Then i go to reboot and I wait. Nothing, nothing at all. Now I try to remove the battery and try again and now none of my buttons do ANYTHING the only sign of life there is, is when I remove the battery and plug my phone to a usb cable and attempt to charge it, all that happens is a red LED comes up. It's probably due to one of the things i installed on my phone that flashes a red LED when battery is low. Please help me with this. My last resort is to give my phone to rogers for them to fix it because I still have a warranty.
Specs: S3 i1747M Rogers
I had aokp jellybean 4.3 as my ROM
I do have a nandroid but its on my phone's sd card
Thank you for your time and I hope we get this to work.

Can you get into recovery mode or download mode?

No there's litteraly nothing I can do. pressing all the buttons does absolutely nothing. Just stays black and no signs of life

bump. I need help fast with this.

Not sure exactly what you did but I hate to say its sounds hard bricked. Mine was exactly the same, with only the red light coming on for about a minute when cord was plugged in with no battery. I screwed mine up with a file I grabbed without reading properly what it was for and in my haste I installed it. After I rebooted it never came back until I got it back from warranty with a replaced control board. Im guessing they didnt even check the internal memory or they would haven known what a dumbass i was since i voided the warranty doing stuff i had done before that mistake. Glad I had made a nandroid before i pooched it so i didnt lose anything after i got it back.

Yeah after some research I found out I hardbricked it but this isn't the first time and I had a warranty for both( different phones btw )times so I guess I'll just send it out. :c

could just be out of juice, leave it on the charger for around an hour then try and go into download mode.

Nasty Bootloop after Flash on Sprint G2

Last night I installed geefree on my phone from the app store and used it to install TWRP. I downloaded a nightly CM11 and an appropriate gapps. Using geefree I rebooted to recovery (never figured out the button combination to boot to recovery "naturally") and installed both of the zips. This could be where I made my mistake, I installed both at the same time.
Now my phone loops, displaying the LG logo for a few seconds, then shutting off and rebooting before repeating the process. I can't seem to get it to go into download mode or the recovery menu. I've tried power+up, power+down, down+up and each of those while plugging the device in, etc. I can get the device to a hardware key control mode, though it doesn't seem too useful.
How can I save my phone? This forum has been a great resource in the past and I'm very grateful for the many tutorials I've followed rooting other devices. Hopefully you guys can save the day once again!

Volume up plus power is how to access recovery on sprint.
What stock sw version were you on before you flashed cm?
Did you wipe data before flashing?
Sent from my LG-LS970 using xda app-developers app

I was using stock 4.2.2, I believe. I didn't wipe the data (shame on me), a bad habit that I picked up from my first rooted device, the Samsung Moment. It didn't ever matter on that one, afaik. Thanks for the reply!
Edit: Volume up and power whether plugged in or not takes me to the hardware key control mode screen.
Second Edit: http://forum.xda-developers.com/showthread.php?t=2432476&page=35 I also found this thread where someone seems to be experiencing similar issues and they fix it with "LG Utility." Is that a PC application? It's a little vague to google, but I've been trying!

I have a bootloop issue every time i flash a rom i have to wipe all but sd flash roms and gapps the i do a restore from twrp and oly restore my boot image only and they boot no prob

I'm kind of starting to suspect my power button doesn't work at all for whatever reason. I have a lot of difficulty getting the phone to shut down, then it doesn't seem to easily power up. It's a strange collection of problems. Would a Sprint repair place be able to fix this?

If they have parts on hand if not either a swap out or a sendoff

Same problem here - bootloop and no download mode - CWM works! - urgently need help
I guess I have the same problem as InlineFourPower (apart from that my power-button has no problem).
I am stuck in bootloop since I tried to upgrade to Kitkat a few days ago. Now I can´t get into download mode any more, nor into fastboot or anything else. Only CWM works.
From within CWM I can successfully flash ROMs but that doesn´t help, since afterwards I am still stuck in bootloop. It is possible, however, to push files via adb-commands while I am in CWM.
Does anybody have an idea how to go from here or how to get download-mode back?

Device is recognized but can´t be mounted - bricked forever?

I tried a few things on Linux.
After terminal-command "ls /dev/sd*" when the device is unplugged from the computer I get "/dev/sda".
When the device is connected via USB, I get: "/dev/sda /dev/sdb"
So sdb is my LG G2.
So I went on to the next command: "gdisk -l /dev/sdb"
As a result I get: "Problem opening /dev/sdb for reading! Error is 123."
Does it mean that the phone isn´t mounted or what? Now I´ve connected my phone to another Linux machine with the same result. It is recognised (p.e. as sdd), but there is no sdd1. Seems as if it is recognized, but can´t be mounted. Does that mean my device is bricked for good? That´s it?

to get the phone into download mode you have to plug the usb cord in and hold VOL+, so to get this right as I have a case on mine, plug the usb into the phone first then hold VOL+ and plug into usb port on the computer.
it does take a loooong time to power down the phone with the button when stuck in a boot loop, just keep holding it until it shuts off, it will shut off eventually!!
plug the phone in while in download mode to install drivers and set com ports, then unplug before you begin your flash with LGFlashTool, hope this helps you out.

Thanks Cronic2009 for your advice.
There are, however, szenarios where download-mode is not accessible any more. Neither by using the hardware-keys, nor by using the adb-command.
After four days of resarch and a lot of trial and error, I finally unbricked my F320L using the two adb-commands outlined at the beginning of that thread: http://forum.xda-developers.com/showthread.php?t=2451696
Worked like a charm.
Thanks everyone for your advice.

no problem buddy, glad you got it figured out, good luck to you from here on out!
FYI, that link doesn't work
I just wanted to ask anyone who might know, since the bootloader of the LS980 is locked, we cannot "break" this correct, so no matter what commands we decide to run through root, we cant touch the true bootloader there for LS980 fail safe? (Besides Acts of God, EMP, ect)

Thanks for letting me know. I corrected the link in my previous post.

Be sure if you use a aosp based rom to flash the ZV8 modem. Your can use dr87 or furnance kernals after you flash the zva modem althought i have encountered soft brick due to this.

so i'm having this exact issue and i don't know how to get out of it. i just need to transfer the radio to my phone somehow but nothing shows up under adb devices. i'm trying to the lg mobile support tool now. its downloading the software. but if it doesn't work does any one have any fixes?

After using tot and flash tool to get back to stock, did you try going into stock recovery and do a factory data reset? I know it sounds stupid especially after a tot but try it. Couldn't hurt

Borderline noob here, so please bear with me...
I have been using TWRP 2.7.0.0 to do all my work, and I was able to get the Lego ROM installed with ZVA. I got into too big of a hurry and forgot to make a backup of stock. I've also been unsuccessful in trying to install ZVC modem and firmware. Thankfully ZVA works as does the LEGO ROM, but I'd like to have stock there to access as well. The stockZVC that's on the Android Development page has been getting stuck (bootloop?) on the Sprint Spark logo. I've done TWRP's factory reset with no success. Any help would be great.
Thanks in advance!

Yes sir I've tried that and more to no avail is there anything I can do through adb I'm on stock recovery phone doesn't stay on long enough to install anything
