FIXED: flashed overclocking kernel on S4, now won't reboot! - General Questions and Answers

Hi all. I have a Galaxy S4 on Sprint and rooted it months ago, still running Jellybean 4.3. Never had any issues with the root until I tried to overclock it just now.
-I was using this guide: http://theunlockr.com/2013/11/15/overclock-samsung-galaxy-s4-sprint/
and followed each step carefully.
-I downloaded the actual kernel from http://forum.xda-developers.com/showthread.php?t=2288309
and used the "AOSP JELLYBEAN 4.3 VERSION".
After the kernel was flashed, I selected reboot. I get the "Samsung Galaxy S4" boot screen but then nothing happens.
I tried holding up volume and power button but it does the same thing.
Need some help! I hope I didn't brick my phone..
FIXED BY HOLDING VOLUME UP, HOME BUTTON AND POWER BUTTON. TOOK FINGER OFF POWER BUTTON WHEN SAMSUNG GALAXY 4 SCREEN LOADED. RESTORED BACKUP.

Unable to boot GT-P6200 in recovery mode

Hi
I cannot get my Samsung Galaxy Tab 7.0 Plus (GT-P6200) to boot in recovery mode.
I tried the following:
1) Switch off the Tab.
2) Press the Power + Volume Up buttons simultaneously until I see the "Samsung Galaxy Tab 7.0 Plus" screen, then release the Power button and keep pressing the Volume Up button. The tab then get's stuck on the Samsung screen, even if I release the Volume Up button. It stays on this screen indefinitely, only option is to reboot by keeping the power button pressed for 5 seconds.
Any help will be appreciated.
Thanks!
same issue

Same problem
any help ???
On which verison thar ur on???? have u tried to wiping data in stock recovery
??
same problem I'm having with my Samsung Gt-p6200, it just boot-loops to the "samsung galaxy tab 7.0" boot loading screen and hangs.. these happened after i flashed my firmware from stock honeycomb to jellybean(the austria firmware, i think that's been posted in this forum).
here's what happened before the problem:
-I flash the stock honeycomb firmware with the jellybean one that i found here..
-after i flashed using ODIN, the new firmware works great, i was even informed that i have free 50GB worth of dropbox space,
the file was named P6200XXMC3_P6200OXAMC3_ATO
- I have used it for a day, until the battery drains and i have to charge, but when i opened it again, it already does this "boot loop" problem
- i have tried flashing CWM with ODIN(as i've read here somewhere that it might help) and do that wipe cache and factory reset thing but that didnt help solved the problem.
hope anyone could help me, im also thinking flashing it back to it's original stock firmware but I dont have a backup of that and I dont know where to get one, I've been searching the net for two days for that stock rom but all i found are the new jellybean ones and some old ones but is uploaded to hotfile which is now deleted or locked.
I hope you guys could help me out and thanks in advance!

Hello guys! Im also having this same issue.
*Using the same firmware that was posted here in xda because i was having trouble downloading those official jellybean firmwares
*The battery got drained
then if i charge it, it will remain in a "blank slightly illuminated screen"
* after a few munutes, the tab gets really warm.
*but if i dont charge it, it will get drained again because it keeps on turning on itself back to this time to the "galaxy tab plus screen"
I cant access recovery mode.
I can access odin mode and can flash successfully with cwm or the same firmware back but the problem still persist.
I havent tried other firmwares though.
4 days passed already and i cant figure this out
Please help
So I had this happen to me yesterday, where it rebooted randomly on me, only to freeze on the Galaxy Tab 7.0 Plus screen. I had custom recovery (TWRP) don't know if that matters, but I was able to access it by holding Power+UpVol but keep it held. It would freeze on the same spot but since I was still holding the keys it reboots a second time and this time it would go into recovery.
I then wipes cache and dalvik, no go. Sadly did a full wipe. Still no going past the tab plus text. So I flash MF1 official 4.1.2 firmware (I was previously on 4.1.2 UK official) still no go. Put in latest 2.8 TWRP and booted into it still with some trouble as I mentioned above. Did another wipe and it then hung on blank screen or so I thought. Took a long time to boot and after a long time, and the Android is upgrading message, by some weird chance I was on the MF1 official rom but all my apps settings everything was saved.
Working 100% now and I still don't really know what the hell happened. But if this helps anyone then all the better!

Note tab stuck in bootloop

Heya, so my girlfriend's galaxy note Tab 10.1 is stuck at bootloop since a while, if you turn it on it keeps restarting. Its completely stock and we can't enter the recovery (idk how to), so far we tried pressing power and volume up button together and it only takes to the "downloading". How to get into recovery and factory reset?
Boot into recovery
I had a similar issue but then realised that the instructions I had been following were slightly inaccurate i.e. hold down power and volume up...... what worked for me was hold down power and volume up, when logo comes up, release power but hold on to the volume.
lets know if you already tried that.

My SM-G920i S6 successful rooting experience

Just wanted to share my experience rooting my S6 successfully.
Don't know yet if I have the deep sleep bug yet - but I will update this thread after a few days of use.
Model: S6 64GB SM-G920i
Firmware: G920IDVU1AOD1 (Updated OTA before rooting)
Steps I tried:
- Used Odin v3.10.6
1. Tried flashing twrp-2.8.6.0-zeroflte.img.tar.
This failed. When trying to go into recovery mode (volume up + home + power button), I just went to normal recovery.
My phone was still functional at this point - but no custom recovery and no root.
2. Tried flashing "CF-Auto-Root-zeroflte-zerofltedv-smg920i.tar.md5"
This resulted in my phone being stuck on the black and white Galaxy S6 boot screen.
Luckily I could still get into download mode (volume down + home + power button). I had to do volume down + power for 6 seconds to hard reset the phone as you can no longer pull the battery out.
3. Then i tried flashing "CF-Auto-Root-zerofltetmo-zerofltetmo-smg920t.tar.md5"
The phone rebooted, then rebooted by itself a 3 times (without reaching launcher), then finally the launcher/lock screen came up!
I downloaded Root Checker and confirmed that I now have root!
I hope my experience can help others out there....
Happy rooting!
Awesome thanks for sharing this tip.
Do post if you have any unusual battery drain with the sleep mode bug. Hopefully it doesn't impact you and us.

Help Me A Lot... Thanks
Thank you so much. This saved my brand new Samsung S6.
For anyone in Australia on Telstra, our S6 build number is: LRX22G.G9X0IDVU1AOD1, at least mine is and I went through exactly the same process as OP.
I can't believe the root for the G920I is labelled as such on the CF-Auto-Root Repository when it bricks this version of the G920I.
Thanks again...:good::good::good::good::good::good::good:
I am running a SM-G920i with a build number LRX22G.G920IDVU1BOE3 (New Zealand-Spark) and can confirm the above fix does indeed work. I was tearing my hair out after using the Autoroot download for the 920i and it reporting as successful in Odin but then remaining stuck on the blue download screen and when hard rebooted using the volume buttons and power button it remained stuck on the samsung startup screen.
I Flashed the 920T version in Odin and the same thing appeared to happen, successful install reported, blue download screen remained, but when I did the hard reboot it went into recovery, installed root as I expected and after rebooting a couple of times is fully operational.
Thanks for the fix (that sinking feeling that occurs when something goes wrong with your new toy has gone).

HELP!!!! Verizon LG-VK410

I have a Verizon LG-VK410 GPad 7.0 LTE. It is currently running Android version 5.0.2. I have rooted, but am not able to boot into recovery mode to install a custom rom(like one from CM). I have tried using the power button with volume down, release power button while still holding volume down when LG logo appears for a few seconds then hold volume down, up, and power button at same time combination. Sorry for the run on sentence! Multiple times and different combinations. I have tried using the following apps: Flashify, Quick Boot, Reboot. All of which failed! So I guess the next question is, am I stuck with Lollipop? Or can I put a custom rom of Marshmallow from CM? I am stunned.....I am really grateful for this site, and the people who take time to help people like me!!! Very awesome in todays world! Thank you XDA!
I was wondering the same thing. I rooted my VK410 using KingRoot, with no issues. Then I'd flash a new ROM, but it never took. After the reboot, it would go right back to the current OS.
