[Q] Blank Screen

So I just rooted my device and then tried to install a lag fix... when I rebooted my phone after the script, I heard the T-Mobile jingle and then it came to a blank screen. When I pressed the power button there was no response. If I press any of the white keys at the bottom, they just light up. I CAN turn my phone off and go into recovery mode.
This thing has kind of shaken me up so I am willing to go back to an unrooted phone.
PLEASE HELP!

Nandroid, my friend.
Since you are able to boot into recovery, do a nandroid restore.
If you do not have your own nandroid backup There is a thread in the Dev forum you can dowload one from. Just search "[ROM] OFFICIAL T-Mo Vibrant JFD ODIN/Nandroid Backup Images 7/29/10 (Tested/Working)" (I can't hotlink yet. sorry)
This is all assuming you have installed clockwork recovery, which you should have done before you attempted any modding of any sort. Also always remember to create a nandroid of your current system before trying something that is still in beta.

i got same problem here and a don't have clockwork recovery :-(

Then you have to use odin if you don't have clockwork...
My phones have been flashed more than Girls Gone Wild..

I think I found a fix that works...
I just went to recovery mode, and deleted all user data.
I then rebooted and still had a blank screen for about 10 seconds, and then my lock screen came up.
Worked for me! Thanks everyone.

Sorry to resurrect old posts, but I would like to know If after rooting and lag fixing it, it didn't show ABSOLUTELY NOTHING on boot screen and you were only able to hear the sounds and the buttons lit up...
I have a Vibrant on this situation and would like to know I this procedure can fix it.
Best Regards.

Just wait 10 mins if nothing do a battery pull...boot...wait another 10. It will boot after that. Had same issue on two vibrants.

Another "my phone is broken" thread

...but after flashing hundreds of times I've never had this problem before.
Flashed one of intratech's frankenstein roms (GT-I9100_XEU_I9100XWKJ3_I9100XEUKH2_I9100XXKI3.tar.md5) and it just stayed on the booting page for seriously more than an hour.
Went back to download mode and flashed the kernel that goes with it (Kernel_I9100XWKJ3.tar.md5) and now I have no recovery mode and no download mode!
I do know how to get into both modes, it just isn't doing it. Instead of going into download or recovery, it just tries to boot as normal, so it's properly stuck.
Not sure Samsung would take kindly to me walking into their service centre with a custom rom etc, what do you reckon?

Try to buy a USB JIG off ebay, plug it in to see if it works

JUST done that actually lemin, thanks.
I guess if that doesn't work I'll have to take it to be fixed.
Wonder what could have gone wrong with the flashing...

Have you tried to remove the battery?

Seems all you needed in the first place is a factory reset from recovery, if the phone is trying to boot, it means the boot partition is intact and you are probably not executing the button combination properly.
Hold Volume up and home, then press power, keep holding the buttons until you are in recovery mode, then do a factory reset and reboot, enjoy your phone

Achilles, you might have thought so, and I wouldn't normally rule out the possibility of me being a dumbass, but really there is no recovery or download mode available. It just doesn't go into either. :-(

You are not being a dumbass, just probably not timing the button presses correctly, if you don't hold those three buttons down until the recovery is actually on the screen, the phone will try to boot normally, talking from experience here
If you are doing this but the phone is still trying to boot normally, then a jig might be the only way to force download mode as you have said that it is trying to boot, so the partitions are intact, a full brick shouldn't boot at all....
Also, I flashed the same ROM, it is not really a custom ROM in the true sense, just a stock ROM with different CSC and MODEM, I really doubt "they" can call that a custom ROM and I doubt they would be able to tell anyway, "it's all stock parts" so long as you didn't flash any custom kernels or anything.
Good Luck.......

Just my humour achilles.
Trust me, as sure as I am about putting one foot in front of the other to walk, I know how to get this baby into download/recovery mode, and it aint playing.
Jig, then service centre it is. Until then, have to use the Galaxy Tab a la Dom Joly.

A500 suddenly died

Hi all,
I thought I'd consult the brains trust to see if anyone thinks this is salvageable. Was using my A500 about 2 hours ago, suddenly the screen powered off. Thinking nothing of it, I held down the power button to restart it. When powering back on, nothing appears to happen except for the power button lighting up. No screen on, no vibe, nothing except the power light on.
Tried power cycling a few times to no avail. Tried the reset button. Tried the Vol+ Power and Rotation switch reset. Nothing.
Out of morbid curiousity, I plugged it into the PC and switched it on and I get an APX driver being installed. So, clearly something is happening here.
It has done this once before and came back to life of its own accord very shortly afterwards, this time it's been dead for quite some time.
Any suggestions? It's well out of warranty now, so I doubt Acer would be interested in it at all.

In the Dev threads, or possibly Q&A, there is a thread called "stuck in APX mode". In there I believe are some steps to see if you can recover.
But, if you're in APX mode, you could probably try NVFlashing the bootloader and recovery the old fashioned way manually.
But look up that APX thread first. Will probably have the answer. I'll see if I can find it in a little while, if you don't find it first.

Thanks MD. I looked up the threads you suggested, and after a lot of screwing around I have installed the APX drivers and used blackthund3r's APX Flash Util 0.3 (The link is broken to the current version) to attempt a recovery of my tab.
Its now sitting at an Acer screen, "Entering Acer Download Mode" while the flash util is sitting at:
Nvflash started
[resume mode]
It's been there for about 10 minutes now, no progress to report. Is it worth just sitting it out, or now that the damn tab shows SOME signs of life, can I just restart it and reset to factory?

And then most bizarre of all. I declared no progress, rebooted it. It went back to APX mode.
Re-ran the blackthund3r tool, it didnt do much so I bailed that. Restarted tab and attempted to load recovery (vol + and power) and it booted normally.
What the hell...

erm for now i would make sure you have all backups of data, cpud etc,.. just incase. you can just sit em on your computer i always try to keep a nandroid of all 3 of my devices each month or so.:good:
edit: and of course keep the link for the thread MD recommended.

Gee. Sounds exactly like mine....
The only thing I haven't tried is an update .zip, but I don't hold out much hope.
Considering parting out at this point....

Yeah, I dont have high hopes that it will last a whole lot longer. Up to this point it has been running Acer OTA updates only, no custom ROMs and no root.
I restarted the tab a little while ago and it went back into APX mode again and stayed there. Some more furious button mashing and attempted restore-mode boots, and it booted normally.
I made the point of wiping it this time using the Vol+ & Power & Rotation Lock trick and its been ok so far.

I have a cousin in Jamaica. She might possibly help (chicken foot and some frogs blood...voodoo you know)
Here's What I think.
You got some corrupt data or a partially bad devblock. This might explain the strange behavior on boot.
Like the tab really doesn't know how to boot.
Personally I would do 1 of 2 things at this point. Either;
1. Root that thing, and try running Timmy Deans root back to 3.2. This should reset your partitions back to normal. Then work your way back to an ICS rooted, Bootloader, and custom rom.
2. Leave it alone, and don;t turn the tab off. Clearly some partitions are messed up at this point. The toggle of the lock usually wipes user data. But the core issue is still there.
If it were me, I would pull out the nuclear missile and go for it all.

Tried the update.zip - nada
Tried timmiedean yesterday, went into Acer Download mode OK, failed....
If dolps is like mien, the first time he tries to go into recovery, it will crash again...

It's baaaack!
Tried blackthunder flash again, failed.
Went to turn off to get out of APX, and it booted!
Now boots, boots to recovery and boots to primary.
I have no explanation.
We will see.
I am suspicious....

I told you maaaannnn, go see me cousin in Jamaica maaaannnnn. She do some good things you see
Glad it's running again.

First, is this a SOD?
I can kill it by booting into recovery and get it back by using Blackthunder flash tool to go into APX and letting it sit for 20 minutes or so. Close the program, unplug, reboot and it is back. I would like to use timmiedean (td) and go back to square 1, but it fails at the image detect ( displays ICS 4.0.3 Civato as the current image, a red X for the new image). Has td been proven to work reverting from ICS? Will a boot recovery reflash and a new ROM flash solve this? Is there another way to get out of ICS back to HC?
Any suggestions/comments welcome!
EDIT: I flashed FLEXxx V4. Shut it off, problem still there....

Really frustrated. Trying to use the timmiedean tool, but it requires that the unit be shut off in the middle of the process, which kills it. Does anyone know the whereabouts of the blackthund3r revert tool, or the .apx package for his flash tool. I can't find it...

I'm done with this one. On Ebay for parts.... GONE!!!
Have an A100 now, rooted, unlocked,. on Relix
1 more A500 coming next week

HELP!!! Stuck on boot screen????

I had rooted my 8 gig Nexus 4 and decided to go back to stock. I downloaded the correct image files from the google website and flashed them using fastboot as I have done many times before with my GN and Nexus S models.
After I flashed the files and do a re-boot, the phone just hands on the nexus (X) startup logo?
I tried booting back into recovery and I get the upside-down android with the red triangle, at this point I have tried holding the volume up key and pressing the power key, but I can't get the menu screen so I can do a factory reset??? I have tried holding the volume down and power keys, both the volume keys and power keys, but no luck getting the menu screen?
I am totally disgusted with this LG product, I NEVER had this issue with any of the previous samsung nexus products. Am I BRICKED?, any help would be appreciated please.
I even tried re-flashing the google system files again and no such luck.

If the phone turns on it isn't bricked. It also has nothing to do with it being an LG device.

Which recovery are you using?
Sent from my AT100 using xda app-developers app

I finally got it to go into the menu screen and did a factory reset and I am fine now. This was one of the worst ones I have worked with trying to flash back to stock. If they would have had a battery you could pull out, I think that would take care of some of the issues. Oh well, I am up and running.

Same problem. Downloaded and installed the Google Nexus 4 image and it said it installed OK, but when I restarted the phone it was stuck at the Google screen.
EDIT: Rebuilt all software on the phone and it is working OK again.

[Q] Stuck on bootloop

I'm stuck on a bootloop on the Samsung custom screen and I can't get into recovery mode. I'm not exactly sure what happened because my it's my brothers phone he says he was clearing his cache. I looked around on the forums to see what to do but I got even more confused. I'm using a Mac, so would it be a bigger problem to fix it? If this was a waste of time and this was already posted before with an answer, feel free to delete it. Thank you.
**EDIT**
I just got it into recovery mode, any help is wanted, thank you.

Is the phone stock? Is it rooted? I have no idea what recovery (stock or custom) you're running. Need more details

Are you trying the 3 button combo to get into recovery?
Hold power +home+vol up. When the blue text in the upper corner shows, release power and continue to hold home+vol up.
