[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.

Stuck at Galaxy S screen after Odin....

Recently i bought a GT-i9000. When I tried to boot the phone, it got stuck in a boot loop. The phone had CyanogenMod installed. I figured I'd try to use an Odin reset with this stock firmware:
http://forum.xda-developers.com/showthread.php?t=1290577
The phone enters download mode fine, the file flashes in odin successfully. But upon restarting, the phone brings up the Galaxy S screen and stays there.
Nothing happens, I've left it for over 15 minutes.
Does anyone have any advice?
Thanks, im pretty new to the Galaxy S.
Had a Hero, Desire HD and an Atrix, but this is confusing me...

Get into recovery wipe everything(data/cache/dalvik cache) again and reboot

Thanks, but it won't boot into recovery.
I boot into recovery by using VolUp, Power and Home buttons correct?

ammm, I normally do VolUp, Home, and then Power, I really don't know if the order is important.
If you can't get into recovery, you should be able to go into download mode with VolDown, Home, Power.
Probably you installed a rom without the required bootloaders, this can happen when upgrading from foryo to gingerbread using a custom rom without bootloaders.
Go to Samfirmware and download JVP rom, make sure the PDA file has "_sbl" on the filename, this should mean it includes the gingerbread bootloaders.
Best of lucks!

Nop it's volup,homebutton,power, hold it until the name of the phone appears and then release, it should enter cause you have a boot image

I don't know if you flashed it with a pit, but if you didn't, try to do it that way.

lg nexus 4 stuck on nexus logo after factory reset

Hi guys. My nexus 4 is rooted. Everything was perfect. I just wanted to do a fresh start. I did factory reset. Then it rebooted. Came to language selection. I selected English and than suddenly screen was black and nothing happened. I restarted again and it stuck on nexus logo. I did downloaded root toolkit 1.63 and it found my model and its selected 4.2.2 automatically. Then it downloaded stock image file and said my device adb error saying need to select USB debugging mode. I can't cause its stuck. Now about the rom it was liquidsmooth rom. Please help me how to go back to stock android 4.2.2. Thanks.

hi,
did u try to wipe cache/dalvik?

Bro I do not know what happened but I did volume up and power for 20 secs and power button again. It showed boot loader mood and switched off the device.

sorry, but for the stock img flash isn't needed just the bootloader mod? The deb mod is useless for this!

Throw it in the trash.

dont use a toolkit, they can create more issues than they are worth. boot into the bootloader, then flash the stock image via fastboot. thats all.

Thanks a lot. I sold it. My bad. Dn wanna use custom rom again.

[Q] Galaxy S4 i9500 stuck on home screen for no reason

Hi guys,
I did a research regarding my problem, found a couple of threads but none of them helped and I noticed my situation is a bit different from most users having this problem.
I live in Brazil, went on a trip to USA for 15 days, kept my SIM card and SD into the phone, just used it to access WiFi, watch videos, make a couple of Viber calls, send messages via WhatsApp, etc. Everything was fine, no problem at all.
Today, when I landed in Brazil, I turned on the phone, entered my pattern and since then my phone just displays that initial screen "Samsung Galaxy S4" and keeps rebooting like crazy. In these last 15 days, I didn't make a single change on the phone. Absolutely nothing. It just decided not to work anymore
My phone is not rooted, runs the latest updates.
I tried initializing in safe mode (power+home+volume up), it shows the android green robot at a glance and then reboots again. I can't even read what is written on the screen, so fast the reboot takes place. I also tried pressing the menu button repeatedly, but no luck as well. Tried removing the battery, turning on without SIM & SD, nothing. When I connect it to a power source, the red led doesn't even light. My computer doesn't recognize it either.
Any suggestions on what to do? Returning it to the shop is not an option as well, cause I bought it out of Brazil...
Thanks a lot, colleagues!

You could try this take the battery out for at least 12 hours , I read somewhere that can work for your kind of problem

I had this with Note 2.
No other option but to factory reset and flash official samsung firmware from sammobile.com
After that we were back to normal. Try that.

sounds not that bad..
try booting on download mode then flash some official firmware from sammobile.com
NOTE: don't flash XXUMH8 or any MH firmware for it contains new bootloaders with the samsung KNOX crap.

I really wish I could solve that without having to install everything again... but anyway
I'm sorry for this newbie question, but how can I flash a new firmware if my computer doesn't recognize my phone?
And what software do I need in order to do that?
Thanks a lot!

Just one more question...
if I really have to install a firmware, isn't it better to flash one from another country?
It seems like Brazil is always one of the latest to get the updates
Which country would you recommend?
Thanks a lot again, colleagues.

I'm totally sure it is genuine.
I mean, I can go to download mode.
When I press power+home+volume down, it works.
But when I click volume up in order to continue to download mode, the phone reboots.
It can't stay stable for more than 3 seconds, let's say.

Ok, but in order to perform a hard reset, I need to press power+home+volume up at the same time, right?
That doesn't work either.
When the small green android robot is shown, the phone immediately reboots. I can't even read if there's something written, so fast it reboots.
Are there any options left or just sending to Samsung?

Try removing your sd card before going to download mode, maybe it's trying to finish a failed update. Try using someone else's empty sd card

Rebooting issues are battery related sometimes. Try another S4 battery and see if it helps

Thanks MaryAnna and Obagleyfreer. I've already tried what you just suggested.
No luck

I tried to give it to Samsung, and look what I've got:
They told me to look for support in the country I bought the phone.
This is ridiculous. It's a shame.
That's when I regret changing my iPhone for a Galaxy.

follow that, the only thing you want to skip would be putting the phone into download mode, since yours already is (full jellybean on mako = lgnpst download mode, or qnpst mode, it depends)
