Black Screen Vibrant

Okay, I know there is many post about this, but none seem to answer my question or help me. I have a Vibrant and I've been searching this site along with google to help fix my phone.
I brought it off a friend so warranty won't happen since T-Mobile is being asses. My phone is suck on the black screen after it passes the big S logo. It stays black, and I get 4 lights bright on the buttons. I've reflashed my phone with Odin and it has not worked. I think it correctly as well. Com3 was on, ran the stock Vibrant with Pitt and Tar with PDA one. That had only got my phone off the complete brick that my phone had gone through, when It wouldn't even turn on.
I got the brick off and now I'm stuck with this program. I did have a one click root fix and I was trying to mess around with clock work. To help answer some questions. No, I can not boot into recovery mode. Yes I have cleaned and wipe out cache. Yes I can go into Download mode, but its pointless since odin doesn't do much for me. No I can not go into the phone since the black screen is there and no I can not flash a update file for some reason.
Saying that, I would be grateful for some help and before hand I thank anyone who comes across this even if they don't help, just for taking time to read this and maybe referring someone else to help me or even pointing me in the right direction. Thanks and once again PLZZZZZZZ HELPPPPPPPPPPPPPPPP.

No, odin is not "useless." I'm pretty positive that you applied Odin wrong.
- Check the MD5 on the files you downloaded; verify they are indeed identical.
- Search for development forum for "drivers"... theres a thread posted by TGA_Gunner. Find that thread and download the version respective to your OS (x86 or x64). This one is proven to work.
What exactly happened in Odin?

Okay. One thing I notice when I try to put my phone into the Android system recovery it says this "
-- Movi_check start .. !!

MBR _Chksum in header :4.1

Another thing, I hit reinstall packages and It says "
-- install from sdcard...
finding update package ...
opening update package ...
E: cant open /sdcard/update.zip
(no such file or directory)
installation aborted.
the drivers I use are the samsung Vibrant drivers for windows 7 64. I know it works because the phone before didn't come up when I didn't use the driver. It always failed and when I install it, than it read my phone. When I connect the phone to the computer, the phone does read it and on odin, it says com 3 in yellow. I than Install pitt and install tar.
The tread you sent me too, I actually went through there before. Both of those drivers didn't work but I found one for windows 7 and it started working for my computer. I could tell it works because the computer actually reads the phone and so does odin. Like I use odin right because it goes through the phone and than says pass at the end. so like WTF lol. I'm pretty sure I'm doing it right tho
Another thing. I used odin a few seconds ago, got the phone to run and it went through the green bar and a blue screen now saying reset came up. My phone than went into androids recovery mode but it started to wipe out data. When doing so, the data said wipe fail. It booted up and now back to the start. Black screen, 4 panels on the bottom lit up and nothing to do.
I'm starting to think it has to do with clockwork I did a partition in it and every since than my phone has been doing this blackscreen with 4 lights.

ANY body ?
help would def be appreciated and even donates if possible. I just need my phone to work

same thing here, know idea, odin says everything passed but still the black screen and four buttons. i also noticed that the sound and tmo splash screen are not in sync. no idea ???? help would be great!!!!!!!!!!! same errors though. also from the partion feature in clockworkmod.

i assume your on windows i don't keep up if there is a working version for mac. Anyway, make sure your update.zip is just named update DO NOT add .zip yourself or the phone for what ever reason sees .zip.zip. I would also go ahead re download your odiin files just to make sure non of them are corrupted for what ever reason.

files all check out good, i can't gain access to the phones sd, i have flashed this thing with every checked build i could find, all with the same result. the master boot record is not adding up.? still have know idea.

have you tried using this.. http://forum.xda-developers.com/showthread.php?t=740558
this work for me and was able to flash to stock..

somebody please help I'm experiencing the same problem as the OP? can somebody point me in the right direction I've been looking for hours

Instead of making us read the entire thread perhaps you could summarize your specific problem.
My initial impression goes like this.
1. Get into download
2. ODIN back to STOCK 2.1
Run odin in admin mode
Use rage against the cage
After getting back to stock Recovery 2e go ahead reroot and flash away

Don't know if this is still an issue, but here's how I fixed it.
http://forum.androidspin.com/showth...yo-That-does-not-Brick!-Downgrading-Is-Fine-)
Downloaded this file knowing it wouldn't work, Had ODIN flash it and got into this weird recovery screen. Just pulled the battery and then flashed back to stock using ODIN.
Helped me out.

Use 512 .pit and True Stock 2.1 from this post
http://forum.xda-developers.com/showthread.php?t=747335
And quit messing with your phone! lol

This is how i fixed mine too, my phone would go through a seemingly normal start up, but the UI would never load and it would stay on a blank screen.
Flash Eugenes373s froyo that doesnt brick. once it brings you to the recovery screen, pull the battery and once again use odin to flash back to stock. the phone should boot up now.

Samsung Tab Help

ok so just a little background, i have rooted droid incredibles, droid x, droid x2, hp touchpad, a few iphones and ipod touches, and some other odds and ends, so i am not a super noob or anything...
but here goes I recently acquired a samsung galaxy tab I800 (wifi only)
when i received it it was stuck in a boot loop and just kept rebooting the Verzin logo over and over again
i can get it into recovery, and the downloading thing while connected to pc
so i have tried heimdall way of restoring or what not..
i know nothing about this SGT, pretty sure its not rooted, but i wouldnt know, and i have no idea what happend to get it into the boot loop,
i have read MANY posts and did alot of searching over the last week and a half before i decided to post..but i must be missing something,
and i really need some assistance...
so if someone can help guide me through this i would be greatly appreciated
Thanks

a bit misleading
SCH-I800 is not wifi only. It is a CDMA device.
P1010 is wifi only.
Look for post on CDMA (sprint/verizon the same).
I can't help much since I don't know about CDMA device.
Good luck.

thanks for the info that i was getting mixed up...its is defiantely a sch I800 which is what it says on the back.and likei said i dont know alot about this tab, just what i was told, which was that it was wifi only..but that was definately wrong info according to what i am told now.
either way i am still stuck on the verizon screen. i also tried the heimdall again see maybe if it would take this time, but still no luck, i feel like i am using the right firmware but i am going to start from scratch now and see if i can get it going..too much misinformation in my head..lol
but if anyone can shoot me in the right direction i will be checking back here alot to see whats up..
thanks again
and thanks to priyana hopefully i can get this thing working..
here is a link to my most recent try

There are several things that make ur device stuck on verizon bootloop.
It can be bad partition system(the wrong pit)-happens when ppl try incorrectly upgrading from froyo to gb/ics, or gb to ics, vice versa.
It can also be incomplete rom - flash interruptions, missing system folders etc.
Go to recovery and check if you get error msgs when you do factory reset wipe and data cache wipe.
Your best bet is to flash a cdma rom with repartition option and tlinclude the correct pit file. You can do it via heimdell or odin.

yes i do get error messages when i try to do a factory restore and data cache wipe i could post a screenshot if that would help, i know it says something like cant mount some files located on E:
one example is
E: install_application_for_customer:cant mount data
then some more files that are unable to mount
and sorry to sound dumb but could you point me to cdma roms? and not sure what you mean about the repartition option..also where or how can i obtain the correct pit file? and as i said in first post not sure what android OS is on this thing nor do i know if it was rooted, and i have no idea how it got into this state
thanks for the help as well..i been a member on this site for a bit, but always just read and get it done, this is the first issue that i have had to post about that i am completely lost on, so your help is greatly appreciated

I did try that route before and it seems like it goes ok, but then when it finishes and i have to reboot (because of the verizon bootloop) and i got to wipe data and cache it has all the red text saying stuff about no being able to mount E: drive files/folders..
i will give it another try just for the sake of trying again
thanks

Hahaha.. didnt realize that. Then just use that pit file to repartition with the choice of rom.

Help needed to revert to stop

Hi all,
A work mate has a S3 GT-I9300 sold debranded in the UK, rooted to what I think was CWC, can't remember now and for some reason his phone has deleted everything and decided it's going to get stuck at boot.
He says can't access the recovery section on the phone so clearing the cache and factory reset is out of the question, he can access download mode though, I've told him to put it into download mode and sent him a link to the latest firmware to download (I9300XXEMC2_I9300OXAEMC2_BTU according to sammobile), he loads it into Odin correctly but gets a error saying "write operation failed".
I've told him to try a old odin and it says can't open com port, so any help would be greatly appreciated trying to clear this up.
Sadly I don't have the phone on me, but I'll be having a look at it myself within the next few days.

Try change usb cable or usb port

Bricked my Galaxy S7 Edge: Odin stuck at initialization, Odin protocol version error.

Hello everyone, hope all is well.
I was trying to install a factory ROM for my Galaxy S7 Edge and during the process, I believe I went and flashed a wrong ROM file (I think it was Galaxy S6 Edge's).
Anyways, due to that, my phone is completely bricked (softbricked? because I can turn it on?).
The problem I'm having is that when I turn on the device normally, it will show the GALAXY S7 EDGE logo but then it'd go straight into recovery mode.
In the recovery mode, it'd say "dm-verity verification failed.. " , "E: failed to mount /system (Invalid argument)". Then when I press Apply update from ADB/SD Card, it gives an error saying "Update from external storage is disabled".
I am able to get into the download mode also and downloaded correct factory ROM and flashed it but it gives me an error saying "Odin protocol version error" in the phone, and in Odin, it stops at "Initializing..." and the program crashes after 5 minutes or so.
I there anything I can do to unbrick this dude? I've been searching all over the place yesterday and could't find a right solution for me so I decided to write one myself.
Thanks in advance and I'll appreciate any help.

First of all why were you trying to flash a stock Rom? Next its a piece of cake take it to your local warranty store and ask them to flash your stock ROM as long as you didn't try to root it they should fash it for you. I've done it many times. Just tell them you were charging it overnight and had it turned off and when you booted up the next morning it was going crazy.
As I said if you weren't trying to root they should do it for you.

I will try what you have suggested. But isn't twrp only install-able when the phone is actually turned on to OS? As far as I've researched, I saw that it needs to have developer mode on.

i am not a dev mate just learn from observation lol but from other devices i have seen them bricked if thats not been allowed in dev options but i am not 100% sure on this one service center is probs you best bet as some one said earlier as am sure if thats not checked nothing can be flashed as that command allows it its like the bootloader is still locked kind of thing

I would take it a service repair center before messing it up anymore, just to be on the safe side, you never know with these things, yeah it might be fixable but if knox isn't voided then you can just have it repaired properly for free.

SM-N910F HARD brick! Desperate and running out of ideas..?!

Hi guys!
I would just like to start by apologizing for making another thread about a bricked note4, however I have read about so much I don't know which advice to go with anymore. I'm also a complete novice when it comes to this.
So long story short, my note 4 started playing up and lagging, eventually not turning back on at all. After endless attempts using odin and flashing what I seemed to have thought was the right firmware, it whittled down to about 1 in 5 attempts of trying to enter download mode (using the buttons) on the phone actually working. Now its completely bricked...no power, no download mode, nothing!
Just like to reiterate, I'm a complete novice,sorry if I'm not making sense, my knowledge doesn't go further than articles and google!
I have tried using kies to recover my phone and it cant recognize it...
I have read about using adb to get my phone into download mode, but I couldn't understand the explanation given well enough to use it...
I bought a 16gb micro sd card and have tried writing an unbrick image to it but I get no response off my phone, also tried another file, possibly sdc? cdc? cant quite remember, but that failed too.
I don't even know if the files I'm using are correct, I got them from a forum on here.
I'm at a loss!
The only hope I have left is if someone is able tell me if any steps I have tried are correct, and possibly provide me with the correct unbrick image?
Also, when I plug my phone into my computer via usb, there is a noise that sounds but nothing else happens, don't know if these means anything. As far as I'm aware I also have correct drivers installed.
Sorry about the long explanation!
Any help is greatly appreciated!
Thanks in advance.
Lucy.

Only logical result from your explanation is you have a hardware problem.
I dont think you are gonna be able to solve it with software...
Time for service visit i guess..

Try the sd recovery method .
First you can try to flash the pit partion .
You can find that on xda .
Just search for note 4 pit files.
Download the n910f pit file with correct csc.
TRY flashing via download mode.
Try flashing .
Use this guide for using sd card to get into download mode if you cant access download mode
