[Q] Won't boot without USB - Vibrant Q&A, Help & Troubleshooting

So about a week ago i flashed a new rom and forgot to remove voodoo before ( it was late ;/ ) and bricked my phone. The only thing it would do is start up to a grey battery screen with the little circle and lines thing then shut off.
So i ODIN flashed back to stock (T959UVJFD) and now the only way i can turn on my phone is if i plug it into a USB first. Either the charger or a computer then start it up and sometimes when the phone is on it will keep flashing USB connected at the top of the notification bar
Anothing thing im having problems with is when i try to use ODIN to Re-Partition my vibrant...nothing happens. it goes through the steps and flashes it like normal but doesn't do anything as far as Re-Partitioning it.
any idea on how i can get my phone to boot up without having to cart my phone charger around everywhere incase it decides to die off on me?
Thanks in advance

I had a similar problem. I have reflashed my Xperia X1. It reboots perfectly if it is attached to a power source/USB connection. However, if I remove the USB connection and try to start it I get the tricolor screen with the following text:
KOVS110
SPL-0.78.0000
MicroP1-787
MicroP2-707
The problem is not the battery. If I boot it while it is connected to a USB plug it starts perfectly. I can then remove the USB plug and it will continue operating. It just won't start without a USB connection.

First you are not bricked, bjorked but not bricked.
What does it do when you try to turn it on without a USB plugged in?
When you have it on and you press the power button does it give you turn off options? Or turn off?
As far as the usb notification, you can turn it off I believe. Is it USB debugging or USB mass storage notification?
How do you know it doesn't repartition in Odin?
Please answer these questions so we can try to solve the issue.

There are 2 ways I can think of to fix this. One way is to charge the phone with the wall charger first. Hold the camera button while pressing and holding the power button. This should put the device in bootloader while not plugged in to the wall and get the PC ready before connecting the USB to the phone. Make sure you have a full charge before you do this because it sounds like your battery died while flashing. If you do this, you should be able to get it connected to a computer long enough to flash it back to normal.
Seccond option, if battery will not charge in bootloader mode or when device is turned off, buy new battery and then follow steps above.
I hope this helps... I personally have never had this problem before.
No connection in bootloader mode
After a rom update has interrupted by 96% (and did not finish) I have no chance to connect my mda vario to my laptop. I still come to bootloader mode but no step further.
Have anybody an idea to solve this problem. Is there any other chance to get a connection to flash the rom again?
Many thanks in anticipation for any assistance!

[Q] strange problem in samsung vibrant

hi,
i'm not sure if this is the right place(or maybe in android dev forum), so let me know if you know a better place to put this thread.
i have a strange problem with my phone:
1. after charging battery stays at 100% all the time, even after a day, only after a reboot it gets fixed.
2. when powering off the phone and connecting to USB, the phone showed green battery icon, now it doesn't it just start to boot.
3. usb is not recognized by the computer anymore.
i cannot use the usual combo to get into recovery, i've managed by pulling out the battery(the download mode procedure) to get into recovery ?!
just noticed another strange thing, in battery status i see unplugged for 0 seconds, even though the phone is unplugged for an hour or so.
i've used nero V3, and thought maybe putting new rom will help.
so i've installed M3 flagship.
but still problems 2 and 3 remains(problem 1 i didn't check yet since i don't have
the accurate battery mod)
thanks for the help.

Those are weird problems. I would just start all over and odin back to stock. Then flash whatever rom you want. Don't forget to check the repartition box in odin

Sounds like it could be an issue with the micro USB port on the phone.
Just to make sure it's not a software issue try flashing back to stock JFD using Odin and see if it continues to happen.
can't odin back as my computer is saying that "the device is not recognized" and the phone still shows full instead of not charging when i disconnect it from the computer.

So while the phone is unplugged and stays unplugged if you pull the battery then put it back in does the battery charging screen still come up on its own even when unplugged?
Sent from my SGH-T959 using XDA App
yes,
while when the phone is plugged in and im pulling the usb out, it still shows that it's charging. only after boot it get fixed.
Plug usb to computer. Pull the battery. Hold both up and down volume buttons together. Plug usb to phone. Then put battery back in. See if that can get you into download mode

if you got the vibrant screen, that's not bad. What error in windows? not recognizing usb? the usb not recognize...does your pc have antivirus with latest def? what os version were you running on phone? have you made any changes to your pc lately like install anything? if not, have you try cold start your computer?
can you get into download mode?
try this [while power off or pull battery, put it back] hold down both volume + and -, now hook in usb cable, it will power itself up and put it into download mode.

i get in windows the "usb no recognized error" i see in device manager "unknown device"
i did reinstall the samsung drivers on my windows 7 x64.
i've also connected it to a vista 32bit with the same error, and my friend's windows 7 x64(he has i9000) and didn't get any alert at all from windows ?!
i've tried with:
nero V3
flagship V3
bionix-v
one more thing is, when looking in SGS tools on battery status i see the voltage/ADC/VF ADC values change all the time but the value of level stays at 100%
update: now i see in SGS tools that the battery went down 80% so this part works fine.

ive got the same problem. Flashing back to stock wont work.. For me it seems hardware related. Ive heard from other forums thats its corrosion in the usb port itself. Im gonna try cleaning it even though im sure thats not gonna fix it. On my phone my battery indicator will stay at 100% untill its been used for about 50% of battery then it will start reading correctly. Of course when you plug it in the charging indicator stays on untill its 100% even if the usb is not plugged in. I flashed back to stock using odin. as long as you have a usb connected notification load up odin with everything plugged in hold pwr+vol up+down untill your phone turns OFF then let go of just the power button you should see the robot digging. Then you can do whatever you want with odin, which at this point of my frustration isnt s*&$.... I really think that its just a crappy usb port design.... Let me know if you find something out.
OK guys, finally I have fixed that issue. Problem is with micro usb(corrosion). You just need take battery out, and clean micro usb port with alcohol and tooth brush very good. That's all what you need to do.

you're only soft bricked, when i've used odin i've had repartion checked everytime and its worked fine (apart from a few freezes but its worked after)
try it by holding the vol buttoms with battery in and plugging usb in
if it doesnt work at first keep unplugging and replugging in and try different usb ports, it once took me 2 hours of doing that before it connected
and it can connect to odin from the phone ! pc screen so keep an eye on odin for it connecting

This is true - more than once I've had different crap interupt the process while ODINing, and ended up with that screen - but ODIN was able to see my phone, so I went through the process as if I had the regular download mode screen, and it worked fine.
thank you!!!!! you are the man. i opened odin up and kept battery in and held buttons and put in usb cable and it worked. no one ever mentioned that odin could see the phone without being in download mode before. i would kiss you if it wasn't for the you being a guy thing. lol

no prob, glad to help
just putting the usb in like that with the battery in only works for me, the other way of pushing the battery in doesnt
so try both ways if there's a next time, it might get moody and not want to work the way you normally do it
the phone ! pc screen's pretty much another version of download mode i think

Is my Fascinate bricked beyond repair?

I was flashing from MIUI 1.9 to MIUI ICS in CWM and all seemed well until upon boot it hung on the MIUI bootup screen. After waiting about 15 minutes I figured I would simply ODIN back to stock and try again as I normally do when I have a problem flashing. In ODIN however I was unable to make it past the boot.inf stage of the flashing. Stupidly I unplugged the usb cable mid flash and tried again, and again same result, it would hang at boot.inf. After trying a couple different stock ODIN files the phone will not turn on at all. Even if I pull the battery and connect the phone to the pc I cannot boot into download mode. When I connect to the wall charger the battery screen does not come on either.
Strangely if I press the power button on the phone with the phone connected to the pc, windows will make the sound of a usb device being connected, however, if I release the power button it makes the sound of a usb device being disconnected. ODIN does not seem to be recognizing my phone anymore since I haven't been able to boot into download mode.
I've bought a usb jib hoping this would solve the problem but it hasn't seemed to work. Maybe I'm doing something wrong.
Please someone help me get my phone up and running again. I've flashed numerous roms before and had trouble but nothing as serious as this.

Thanks for that. I went through his guide but unfortunately I think my problem is a little more serious. My phone will not turn on at all. I cannot boot into CWM, download mode or boot normally. The screen just remains black. It doesn't show up as a recognized device in windows but when I connect the usb cable it makes a sound of it being connected.
If any has any ideas on things I could try I would be really grateful. I bought my phone out of contract and can't really afford to buy a new one right now.

Can you "3 finger" into recovery ?
Sent from my SCH-I500 using xda app-developers app
No, when I try to use the 3 buttons to boot into recovery the screen stays black.
Another strange thing it's doing is when I connect the phone to my Mac with the SD card in the phone the Mac will continuously popup a window that asks whether I want to connect the usb device to the Mac or my virtual machine. It flashes so fast I'm unable to click either option. If I connect the phone without the SD card in this menu never comes up but I'm still unable to boot into download mode.
Hmm....I've never heard this before...have you tried plugging phone charger in ( wall outlet ) and let it charge 8 full hours

I charged it from the wall charger overnight still no luck. Yeah, I bought it a year and a half ago used from ebay. I think it's really strange too. I've had plenty of hiccups flashing roms before but it's never been something ODIN couldn't fix and I'd at least be able to get into download mode.
I think you are going to have to use UnbrickableMod.
Thanks MM. I bit the bullet and bought a used Galaxy S II. I may still try that unbrickable mod so I can give my Fassy to my mom who's overdue for a smartphone. I've never used a soldering iron though and not too certain how successful I'll be.

Have you tried the wall plug trick?
I had been running a Fascinate rom on a Showcase for almost a year & the same thing happened to me. Initially, the battery had run completely down and after full charge, I had nothing but bootloops. At first I could connect via odin, but could not complete flash.
After messing with it & yanking out the cable as you did, I had same issue, blank screen, pc would beep but that was it, pc/odin would not recognize or show the comm port. I would get unknown device.
Ultimately, I successfully repartitioned & odined a stock Fascinate Froyo EB01 rom by doing several things -- not sure which worked, but perhaps might work for you rather than soldering
First, I fully charged an oem battery using a spare battery charger (not in the fassy)
After charge, I put the batt in the fasc & plugged the fasc in to the wall charger while holding down the volume button & got the download mode to show up.
I left batt in when I unplugged from wall & the download mode stuck.
Odin still didnt recognize on my laptop, so I tried 3 other machines till I Odin finally saw the fascinate, at which point I odined Froyo with .pit & repartitioning as my starting point, then clockworked & rooted etc. I think I left battery in during the flash, then reflashed later in download mode with battery out.
I was also successful using heimdall a few times, when another pc wasn't available & odin wasn't playing nice. Was very odd, as 2 of those laptops ALWAYS worked fine with odin & the fascinated showcase before. Now they still won't recognize, but I can easily odin if I try diff computers --- some windows 7 some xp & some vista.

I had the same issue. I think it had to do with the battery being too low. I think that ODIN could have a check in place to allow only to flash if the battery is not clos to low in case things go wrong. I had a second fully charged battery and when i read the above post, i changed the battery across and it set it to download and ODIN eventually detected it. Thanks for the help guys.
I have a similar problem, I was on PA JB rom 2.18, and I decided to flash latest devil kernel [1.5.2? or something like that]
so then it would just boot into devil recovery. and that's all. Tried to flash pa rom over it [to get stock recovery back] but it failed. also it had lots of errors about mounting.
So I did advanced restore, and chose to restore boot from other JB backup. This just made it worse, bootlooping into an android recovery with a "!" triangle, then immediately rebooting, over and over again..
So I put into download mode, and heimdall a boot.img extracted from the JB rom [paranoid android], and it still didn't work right.
So then I heimdall'ed the atlas.2.2.pit, thinking the partition was screwed. Then I was booted into cwm 6.x! So I thought I was out of the woods, and wiped, then flashed PA 2.18 jb rom, and then rebooted.. and then I had no samsung logo bootloop. I could tell cuz it was dark, and I could see the backlight coming on and off. on, off... on... off... endlessly.
I tried download mode, and it didn't work. That's when I got scared.. I tried it again, nothing. just the black [very dim black, because of super amoled technology] screen, coming on and off..
So I finally tried taking the battery out, and then it went into download mode!
But I still cannot figure out why it will not let me flash any rom. I'm gonna have to boot into windows and odin back to EH03.
Good thing I have a 3-4 day old backup.
So, do not use devil kernel unless you want a softbrick.

I think the problem is you used the wrong Devil... the latest is 1.6.1 and the older ones will not work with the new partition layout. Get it from http://rootaxbox.no-ip.org/derteufel/
Here is some FYI for you guys. If you are using a pc with a USB 2.0 or higher then it provides the power to go into download mode for Odin. That's why people say to remove the battery and then plug in the USB cable and hold the volume and power to go into download mode for odin. IF you are using a desktop then it's best to use one of the hardwired usb ports on the back of your pc, if it's a laptop then they are all hardwired to the motherboard. USB 2.0 and up all provide power through the usb port, therefore if you leave the battery in while Odin'ing it may not be a good outcome, this is just a suggestion.

It's probably just a precaution so you don't accidentally reboot the phone while flashing or something like that. Every guide I have read says to pull battery before using Odin so I do... and I haven't had any problems. I think it'll probably work fine with the battery in, but why bother taking the risk?

how would the battery cause the phone to reboot?
I have never Odin'd without the battery. And I never had any problems

[Q] i777 Does Not Turn On

So I have had the phone for a while and have been running Task's AOKP ROM with minimal hiccups.
I had the phone charging and when I unplugged it it would not turn on.
After pulling the battery and rebooting, I noticed that the stock AOKP boot image appeared (as opposed to my custom one) and the phone got stuck in a boot loop. Booting in to CWM I could see that something had gone wrong as it kept popping up about a recovery log file not being found.
When I tried to reboot the phone it did not do so, even after charging. No sign of life at all. Buying a new battery didn't help - it still shows no signs of life at all.
Anyone any ideas? Anything I can try? I'm willing to flash back to stock if that's what it takes but I can't even get it to power on in to CWM to do so.
Would the USB JIG help?
The jig might help. If you have one on hand try that first. Otherwise, try to boot into download mode with the battery out. Do the following:
Pull the battery and leave it out.
Open Odin3 (v1.85 recommended) on the desktop.
Have USB cable plugged in to appropriate port on computer but not connected to the phone.
Hold the vol down button (or holding both volume buttons is okay) but not the power button and plug the usb cable in to the usb port on the phone. The computer will supply the power.
If you get download mode, and Odin recognizes the phone, flash the full stock package from the Download Repository. UCMD8 is the latest stock.

Hold the vol down button (or holding both volume buttons is okay) but not the power button and plug the USB cable in to the USB port on the phone. The computer will supply the power.
If you get download mode, and Odin recognizes the phone, flash the full stock package from the Download Repository. UCMD8 is the latest stock.

So I tried your suggestion but plugging the phone in with the battery out does nothing. No sign of life. Do I need to have specific drivers installed?
I have the most recent SAMSUNG drivers for the S2 found here on XDA and have ODIN 1.85 installed but the phone just remains blank and nothing happens. Any other options/thoughts? I it perhaps the USB charging port? Or is it fully bricked? Any way to check?
EDIT: With the phone plugged in and the battery either out or in, the top of the phone does become warmer so it seems like the USB port IS working perhaps? This is very frustrating...
I'm far from experienced with this sort of failure. I can only make suggestions based on my collected knowledge from reading the forum every day, and my understanding of trouble shooting principles. So don't take anything I say as definitive.
Generally, if the phone shows no sign of life, that is the definition of a brick. If it shows no sign of life except getting warm when plugged in, that is a different symptom than "no sign of life."
Do you have a jig, and have you tried inserting the jig with a charged battery in the phone? That would be the third troubleshooting step to see if the phone can enter download mode. 1) standard method to enter download mode with a charged battery. 2) attempt download mode with the battery out 3) attempt download mode using a usb jig with a charged battery.
As far as the usb port, were you aware of any problem with it before this issue came up? As far as I can remember from what people have said in the forum, they know that they have a usb port issue because of wonky behavior, before complete port failure. Also, most people report that their phone still boots when they have usb port failure.
I always hate to suggest spending money, but if you are unable to get into download mode through any method, then I can't think of anything else to do but send it off for repair.
I just resurrected my S2 two days ago when I bought my laptop. Used a jig I made from a YouTube video and all went well other than some slight USB issues like the phone thinks its plugged in sometimes.

Bricked phone
I was using CyanDelta for over months without any problem. Today (1 December 2013), I downloaded an update of about 21 MB of Cyanogenmod Nightly 10.2 for Samsung Galaxy S2 SGH I777. While trying to install it, the phone booted into recovery and installed it. However, during the process of Upgrading, i.e. when the screen says “Android is Upgrading”, “Optimizing App”, the phone got stuck at “Optimizing app 271 of 313”. I waited for about 30 minutes before I manually switched off the phone using the power button. Then I restarted the phone and saw a new boot logo of cyanogenmod; but it got into boot loop. Then I booted into recovery and manually installed the new zip (of 1 December 2013) found in CyanDelta folder. Still the phone could not boot. Now I saw “Samsung” logo only once and then the phone completely turned off. Now I could not turn my phone on, nor could I boot into recovery or download mode. Also I fully charged the battery before flashing the new Zip.
I tried all other steps to boot my phone like removing the battery and pressing power button for a minute, plugging the usb cable into PC and pressing the volume down button and also all sorts of other key combinations. Nothing could boot the phone. Please help. Is my phone completely bricked or is there any issue with my battery ?
Phone : Samsung Galaxy S2 SGH I777 (AT&T)
ROM : Cyanogenmod Nightly 10.2
Battery Condition : Poor (But it was fully charged and also charger was plugged in while flashing the Zip)

Sorry for the same post being posted thrice. And I have already tried all the methods except for the USB Jig method. I may think of buying usb jig, but is there any specific usb jig available for S2 sgh i777 ? And my phone usually gets warmed up when I put in my battery, but could not do anything with the phone.
