Recently i tried to install firmware on my Galaxy tab 10.1, but it resulted in a bootloop, and now i am on the samsung screen. I tried to install the firmware with mobil Odin. The firmware i used is P7510XEULPH_P7510XXLPH_HOME.tar. I dont know what to do to get my tab working again, because when i try to boot into the recovery, i get the flicker screen.
If anybody could help me i would greatly appreciate it.

Sounds like you soft brick your tab. Looks like your gonna need to whip out the PC and find PC version ODIN even though the screen stuck on flicker it will still connect well at least it did when I soft bricked my SGS 2. Well good luck guy I knw I had a few days of fun when I was trying to fix mine.
Oh ya one more important thing check in your device form in Q & A Chechen sticky always a lot of useful stuff or might even find a quick fix from fellow XDA fanatic like me.

Not sure if you are still stuck, but if you boot into recovery and then clear cache and user data it stopped the boot looping for me...

In theory you can switch off the tab and plug it to charge. It should charge as you do not hard brick it. If you can slash your tab via Odin, try to flash it two times, one by one not letting it to boot android and samsung logo after the first flash. After the second flash, reboot and hold the volume - button till you get into stock recovery mode. then wipe data and wipe cash. then reboot again.

Agh!
I recently rooted my SGH-I777, flashed it using Clockword Mod Recovery, and then rebooted into recovery using CWM. But instead of rebooting into the recovery menu, everything went black. Now my phone won't reboot into recovery mode at all (not even with the Volume Up + Volume Down + Power combo). Instead, it gives me the Galaxy S2 GT-I9100 startup screen with the yellow triangle and then the screen goes all black, with quick flashes of dark gray.
When I removed the battery (to get it out of the black screen loop), returned the battery to the device, and plugged it in (without powering up the phone), the "charging" screen with the charging battery indicator flashed on the screen for a moment, and then back to all black flashes.
I removed the battery, SD card, and SIM card for about 20 minutes because I've read that can sometimes help. No dice.
I'm running ICS 4.0.3 with a Siyah 3.4.2 kernel.
This is probably either really bad or no big deal and I'm lame for not figuring it out, but... HELP! (Please? :fingers-crossed: ) I know this has been asked, but the other threads I've found have been able to get to recovery mode, whereas I can't seem to get to that point.
If you need any other info, let me know!

No d/l mode, no CWM. = brick.
no offense but im pretty sure your just not holding the buttons right.
CWM= hold both vol, then hold power, let the first screen blink once, come back, then let off power is my trick.
download, you can just hold vol buttons and insert USB belive.
Somebody used rom manager!

A-ha! Ok, so definitely no on the CWM combo, but I do get a menu using DL mode. Thank you. Seeing at least a menu made me feel much better.
I re-flashed the initial kernel, but no change. Still stuck in perpetual black screen boot loop.
I'm not opposed to doing a full-fledged wipe using Odin, if that's an option, but I've never looked into it before, and I'm currently feeling pretty gun shy when it comes to getting creative with any new tricks.

If you want stock, flash a stock ROM, or stock with root, with Odin.
If you want custom, after you flashed that custom kernel, you CAN get into CWM and flash a custom ROM.
and NEVER use ROM manager, hell it was a joke when it came out, sorry koush
EDIT:
and if you do go custom, dont forget to wipe data/factory reset in CWM before flashing.

You rock. Thank you a ton for being so patient!!
To any other fool who gets into the same mess, I went into DL mode (volume up + volume dwn + usb attached) and opted to let this do the rest of the work because it was the only option that didn't give me a heart attack: androidarea51.com/samsung-galaxy-s-ii/samsung-galaxy-sii-(sgh-i777)-att-only/
From there, I had the option of rebooting, initializing a factory reset... all of the menu options I wasn't seeing when I couldn't figure out how to get into CWM mode. Good luck!!

I know, I know (and this is a dumb excuse, much like using rom manager in the first place), but the tutorial I was reading made it seem like it was a good option. I hadn't used it in forever and logic coupled with faith in a perpetually broken system paves the road to hell, but I figured, "There's no way it still sucks as badly as I remember!"
Don't think that. Ever. My mistake.

Samsung Galaxy s2 i-777 does not turn on
okay so I read through this thread and I still don't know how to fix my issue. I rooted my phone using Odin v 1.85 and used siyah 3.4.2. I did it successfully and everything was good. I then gave the phone to my cousin and he said he performed a factory reset to get rid of everything on the phone ( contacts ,etc). Now when I turn on the phone it shows the samsung galaxy display with the triangle and then the screen goes black and just blinks. It still goes back into download mode I just dont know what to do to fix the problem. I know I'm a noob but please HELP!!!

Have you tried flashing back to stock using odin? BTW it is not good etiquette to necro a thread that has been dormant for almost 9 months.
Hi there, i finally got round to trying to root my galaxy s2 having put it off for a while due to the fear of it all! I only really wanted to root it to move the games over to my sd card since they were taking up all the room on my internal memory!
Anyway now that i have done it, i have really messed up my fone. My fone will not boot anymore, it will only go into download mode. It won't go in recovery or boot at all. It goes to the galaxy s2 logo and displays a yellow sign at the bottom of the screen. I have tried numerous tutorials online to try and fix this problem. I have tried 'Phistachio's guide on this forum and i still couldn't get it to work. It just comes up 'Fail' when i try to flash everything. It flashes the kernal fine, and it also flashes the pit file fine, but the rest it just fails on.
I really need my phone up and running again through any means! If anyone has the time to help me, that would be fantastic! I just need it fixed, and it feels like i am running out of ideas on what to do next.
Im sure i was on ice cream sandwich when i tried to flash the device so i followed this tutorial on galaxys2root....com (i can't post the link)
But it after this, it never booted.
Please help!
Thanks

Hi!
I can see that you are stuck on bootloop. There are a lot of options to get you started on fixing this.
If you can go to download mode, you can just flash a stock rom/firmware via odin..
If you can't go to download mode, you use a usb jig to get you to download mode (if you don't have a usb jig, you can borrow one near you.. the link is on my signature).. and once you get to download mode, you can flash a stock firmware/ rom..
you can get/ download stock firmwares on sammobile.com but you have to have an account there. don't worry it's free
I hope this helped
Cheers!
usb jig n flashing stock rom over pc odin the best way

Hi.
Firstly take out the fear in you n then try out anything with yr phone for wat u need.
Now find a jig which will reset yr binary count to Zero.
Find your countries latest stock rom on xda or sammobile.

Stock rom tar file (which u get after extracting downloaded rom )
Install samsung mobile drivers on yr pc.
Put yr phone to download mode manually (vol down +centre+power)
Then open odin n don touch anything other than pda.
In pda select the md5sum tar file.
Then connect yr phone with usb cable to odin n after u find an yellow vom port u ve to start n wait for stock rom to get
Flashed n with fear don remove cable in the midfle of flash n once done it will restart n work the way it was before.

Like said here before, if you installed CWM on an unsafe Kernel (usually Stock Kernel present on 4.0.4 and 4.1.2 Stock Firmware) and after that wiped your data/cache etc. there is a good probability that you hard-bricked your device. Not even JTAG will help, if it`s the eMMC hardbrick.
Try to get into download mode and flash a Stock 4.0.3 Firmware and if you can`t then try a USB Jig to get into download mode and if that doesn`t work you probably hardbricked your device as described above
Read this on more info about eMMC superbrick:

I hope u Guys will teach me how to fix this situation.
I Used Odin 3 1.85 to install CMW. While the installation process taking place an error occur. and automatically shut down. show up an message
"firmware upgrade encountered an issue. try to connect kies...." after 10-15 mins showing this message
display gets black and stuck. i tried everything that is possible to me. press and holding power+VOL up+home together, leave it for charge etc.
but nothing works
COULD ANYONE HELP ME ON THIS SITUATION. :crying:
As said before, Try power + volume Down + home and flash a stock firmware through Odin
And is there still any life at all? What about when charging. Is there the charging animation?

I love comments like this. Well if you don`t read properly how and what to flash at what time to your device and just do as you think is right then you are going to end up with a hardbrick. That`s nobodies fault but yours. Why did you buy an Android phone in the first place if you can handle an IPhone better?

If you have an hardbrick and you can`t even get into download mode, what do you expect people to do? We are normal human beings here, there are no miracles here. If you have an hardbrick, you can try to repair it via Jtag or send it to a Samsung service center if you are still on warranty but if you complain about Android and how much it sucks you won`t be making many friends here, since this is an Android community.
Hi all,
Have a really bad problem, just rooted a galaxy s 3 for a friend, i've rooted many, he was on 4.1.1 i used the toolkit as i've used it before.
The root process worked well and now the phone boots up, makes a sound and then doesn't show anything on the screen.
Now nothing comes on the screen at all although it does make a boot sound (the samsung logo noise) the only thing i get on the screen is the galaxy s III logo and a small red exclamation mark up the top left.
Really would like to get this back on.
My friend bought it from singapore, although it is a i9300.
I can get to recovery and i can also get to download mode.
Any ideas?
If it is a I9300 then factory reset from recovery or flash a stock rom .

Actually sorted this now, I used the older toolkit and it caused this issue. Wiping it wouldn't have helped.
Used the new toolkit and all is well again.
Sent from my GT-I9300 using xda premium
I'm suffering the exact same problem (likely for the same reason - used older version, although possibly just because I messed up on my own).
@dladz, or anyone else who might be able to help, could you please give me a pointer on where to go after downloading the newer toolkit. I have a vague idea but I imagine it would be better to ask at this stage before I really mess it up myself.
If anyone could help you'd be a life saver
---------------------
Edit: After prodding around and "fixing" it I thought I'd leave this information for other noobs so they don't ask the same question/harass dladz like myself.
Simply boot up holding the vol down and home button, connect via USB and open Odin.
From there make sure that only Auto Reboot and F. Reset Time are checked.
Click PDA and select C:\Samsung Galaxy S3 ToolKit\root\GT-I9300\boot-stock-ella-GTI9300.tar (From the toolkit - http://forum.xda-developers.com/showthread.php?t=1703488)
Hit start and wait for the square on the top left to turn green and say pass. The device should reboot and be work again. As I'm a retard you may decide not to follow these instructions for your own safety and the safety of your device, however it worked for me.
Apologies for being a pain in the arse, I'll go back to lurking quietly and I'll try not to break anything else.

how do i do that exactly?
Is this just an untouched device, that you have not currently flashed anything to? I've heard of this with galaxy sii. You can learn fastboot and adb, and re-install a rom which is similar or exactly the factory version. Otherwise, it sounds like a warranty claim. Maybe try getting to your recovery, wiping cache and/ or a factory reset, then see if it boots?
