[Q] HELP WITH WHITE SCREEN PROBLEMS MEGA SGH-i527 - Samsung Galaxy Mega

Just rooted my Samsung mega sgh-i527 and it was working for two days until I decided to unlock new fonts in the ROM. Stupid decision knowing that I didnt do my research. Now when rebooting it just stay on the loading white screen not allowing me to access anything. I try to hold-power+volume+home screen button to reset my date and cache and then reboot the phone which I thought it might work. But it didn't. I have read a little about if this occur then its consider a "dead phone"and I might as well just purchase a new one. If this is true then I am pretty Fu*k. If anyone knows anything about this issue please HELP. Donation will be given out . THX.

[Q] Bricked S5830, please help me

Hi all,
I have looked for a similar post, I found out that many people experienced something like that trying unlocking their phones, but I haven't found out any solution.
Here is my situation:
I have tried to unlock my s5830 (orange spain carrier), I have used a method which it seems to be dangerous for the phone, but of course I have found out it was dangerous after I have already tried it
Anyway after I discovered the unlock number contained in the perso.txt file in the efs folder, my phone restarted without service once and after that it went in a bootloop mode, it goes on a download mode, but there is no way to get back recovery mode or a normal boot.
I flashed the s5830 several times with many firmware, but no one worked, and the phone is still stuck in an infinite loop, in which I am not even able to see the samsung logo coming out at the very beginning.
I know many phones got bricked in this way, I wanted to know if anybody has been able to recover the phone or if anybody know any possible solution.
And if not, do you know if the warranty is covering this problem? I just got the phone a couple months ago; i have unlocked other devices before, but this is the first time I have experienced a problem so I am quite new about warranty as well. Please HELP ME
Merry Christmas guys!!!
Thanks in advance

with the cellphone off, put out ur baterry for a minute, then maintain ur finger into the volume down button and the power button tell a friend or if u can alone insert the batery while quickly pressing volume down and power button to get into download mode, and flash.
Hehehe,bootloop is horrible,you just have to get in download mode & flash with 2.3.4 firmware with Odin,just that steps and you save your SGA.
I got bootloop many times and Odin saved me.

he cant go back in recovery mod............
If you can go to recovery mode than you can just wipe the data and cache. This saved me many times. Otherwise on what ever OS you may be , just create new user name after removing samsung android drivers. Login from new user name and than re install drivers again and now flash your phone from firmware which was installed on your phone before you bricked it. This helped me a few times.

Helping to make your Christmas Merry
It seems that you've already received a lot of help for unbricking your device. So I'll try to help out in unlocking your phone after you finished unbricking it.
This is the method I personally used on my locked Ace:

I have tried the XXKP9 again, it is not working, as usual Odin ends to load the firmware and then it goes back in the endless loop mode....there is no chance to get it back?

thank you very much I will follow your advice...IF I will be able to get my phone back which seems impossible =(
@dr_vishal
Thank you first of all, I have tried to uninstall and reinstall the android device driver, but it doesn't seems to be the problem, Odin ends with a "PASS" at the end, I guess there still is comunication in the between the two devices...
Hopefully it will be a Merry Christmas =)
It's not impossible. I'm relatively new here but I have noticed quite a few "bricked" threads already. Most of them (if not all) have been able to fix their device. I haven't seen a single person permanently brick their device, so I would guess that your chances of fixing it are really high. Just be patient and keep describing your situation and more experienced help will certainly arrive. I'd really like to help out but I have no idea how to fix it as I have not experienced bricking my phone yet.
Anyway, if the method for unlocking I suggested works for you kindly press the Thanks Button. Merry Christmas!

Guys,
I am out of ideas, I have tried each single firmware I have seen around internet, no one is working, any tip or advice or suggestion?
I messed up with the efs, and I guess that's all, the phone is gone....now it needs a JTAG or whatever is its name....
maybe to get the warranty still valid I should broke totally the phone over charging it....??

http://forum.xda-developers.com/showthread.php?t=1153310
just a thought
a lot of people have talked about reflashing it and all but have you managed to get into the recovery mode at all once you have reinstalled the rom with odin? if you can get to that you just need to hit factory reset, wipe cache and wipe dalvik and normaly after that it will work fine... so far ive been stuck in soft brink 3 times and each time doing the wipes from the recovery mode has worked...

I've tried to use the oneclick, but it seems it doesn't recognize the phone, since, i guess, it's made for a galaxy s.
The others are not my case, since I am able to get download mode, and all these are made to can get it back.
Anyway I found out a post in which the people were talking about the s5500, which apparentely is similiar to my device, and the owners of that model experienced a similar problem doing the same process....anyway in that post the people needed to use a Jtag, which is the only way to get it back....so I though it could be the same solution for my problem...but I don't know anybody with Jtag, so the only way is contacting the service center.
thanks anyway, when I will be back at home after Christmas I will try to find the ticket and I will probably try to get it back in warranty, since is preatty new...
@torchwolfery
I am not able to reach recovery mode, there is no way to get it back, even flashing the phone with different firmwares, all I got is download mode, and apparently that is completely pointless...since the only change in the phone behavior is that if i install a certain firmwares it doesn't even have the back-light working when it is stuck in bootloop.
Warranty is your only hope (as it was mine once and it worked).
I didn't think it was possible to brick these phones. There I have tried so much to try and brick it but I have not been able to as it still always goes into 'download' mode. The only advice I can give you is double check that you are using the correct version of Odin which is v4.38 and that you use cooper v1.0 as your OPS. If dont mind me asking, but exactly what did you do or do you remember the steps you took to brick it? What buttons are you using for 'recovery' mode.
Also please clarify if Odin is going in a loop or does the phone come on and then keeps rebooting? If it is the phone that keeps rebooting, then wiping cache and data partition should do the trick. This can be done by going into recovery mode (which I am aware you cannot get into) or if you can manage to get into the dialler quick enough before the reboot, by dialling *7267*3855# and that should format the relevant partitions (data and cahce) and bring it back to factory settings. Without further info, I cannot really tell exactly what the situation is.
The fact that you are getting 'download' mode, I dont think that it is bricked because it will still allow you to write the relevant directory/files to the relevant blocks. Either way, would be interested to know.

Bootloop after unrooting

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.

[Q] HELP! My Samsung Galaxy S3 International I9300 is stuck in bootloop!

Hi,
I have the exact same problem as some of the other bootlooped/bricked Galaxy S3's, i was on a custom samsung 4.1.2 rom for about a month and while browsing the net today it crashed went in bootloop now i cant get out, went into cwm recovery mode and factory reseted but didnt do anything.
The problem now is i cant go back into clockwork mod at all, so i went into download mode by pressing power + voloume down and menu button and went into download mode and opened odin flashed a stock rom, however it just keeps saying fail after nand write.
I now tried a custom rom and the same issue occurs and it fails, now when i pull the battery out and turn it back on all i get is a error message saying 'firmware upgrade encountered an issue please select recovery mode in kies and try again' can somebody please helppppp me i literally have no phone at use at the moment!

If you have a jig you might be able to bring it back to life and get in downloadmode and retry flashing a stock rom again. Pull the battery for a minute, reinsert it and use a jig. If you don`t have one try to buy one. Good luck
factory reset is your only way

I relate to you guys for that's exactly the same problem I'm going through. After successfully updated to the Jelly Bean 4.1.2 UK BTU international version and beautifully restored all my apps via Titanium backup I then proceeded to restore as well my EFS folder through a program named kTool, ignoring its warning message cuz I was just following a tutorial put out on a S3 Brazilian forum believing there was no danger at all.
Well, to my sadness and despair it returned on a bootlooping mode, if you will, and I did everything firstly tried to recover then wiped cache, dalvik, data, formatted the whole stuff and finally installed again via odin in download mode the same jelly bean 4.1.2 all to no avail
Now I got the bootlooping and when I press volume up + power + home I get a screen with a seemingly dead robot with a exclamation sign in its chest. Please what do I do in order to fully recover my S3?? this situation is killing me.

Dude, I've watched that vid but haven't tried that procedure so far, matter of fact I will do that however flashing an earlier version of the ROM, perhaps JB 4.1.1 or 4.0.4 or yet the current one from another country since the UK BTU version I downloaded was somehow corrupted. Anyhow thanks for the heads up to avoid factory reset and reboot it instead, hopefully I'm going to manage to get the CWM recovery screen cuz now I get only this:
Android system recovey <S3>
Volume up/down to move to highlight:
power button to select.
Reboot system now
apply update from ADB
Apply update fom external storage
wipe data/factory reset
wipe cache partition
apply update from cache
Right below it appears, along with the fallen/dead robot, the folowing message:
# MANUAL MODE #

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?

[Q] Galaxy s3 screen bootloop

Hey guys,
I have a galaxy s3 (I9300) and I've had it rooted for some time now. I started using CyanogenMod 10.2 nightlies a few months ago and they've mostly been fine. The odd issue comes up but I've been able to work it out. So, a few hours ago my phone just turned off of its own accord and started to bootloop, but on the "Samsung Galaxy S3 GT-19300" screen, not the CyanogenMod screen (to clarify, this screen comes up first then the cyanogenmod one usually). I've tried booting into recovery (CWM 6) but it just shows the CWM boot logo thing (that cog with the hat) and then loops back to the galaxy s3 page. I've also tried putting it in download mode, and it seems to stay on the warning page longer than it does anywhere else, but it wont let me actually put in it download mode from there.
I had a look around google and saw people have had the same problem, but everything I could find was when people had flashed a new rom/kernel etc. and something had gone wrong in the process. The weird thing about mine is that I haven't changed anything, even downloaded any new apps, for maybe a week, so it's not like something suddenly changed. I also wasn't using it when it started, it was just sitting on the table next to me.
Usually I can work these things out, but I'm stumped here. Any help would be really appreciated.
Thanks in advance!

Hey guys,
I have a galaxy s3 (I9300) and I've had it rooted for some time now. I started using CyanogenMod 10.2 nightlies a few months ago and they've mostly been fine. The odd issue comes up but I've been able to work it out. So, a few hours ago my phone just turned off of its own accord and started to bootloop, but on the "Samsung Galaxy S3 GT-19300" screen, not the CyanogenMod screen (to clarify, this screen comes up first then the cyanogenmod one usually). I've tried booting into recovery (CWM 6) but it just shows the CWM boot logo thing (that cog with the hat) and then loops back to the galaxy s3 page. I've also tried putting it in download mode, and it seems to stay on the warning page longer than it does anywhere else, but it wont let me actually put in it download mode from there.

can you at least enter download mode after a long time you said? if not, try pulling out the battery for 5 minutes or more and re-insert and enter download mode. i hope it's not sds! good luck

Nope, if I press the volume up button to go into it, it just goes back to the bootloop. I'll try the battery thing though, thanks!
Nope, it didnt work, I left it out for maybe half an hour and nothings changed :/ anyone else got any ideas?
SDS thread and BootLoop identical questions posted .
What does Product Code say in download mode .
But if you cannot get to download mode then you need a service centre repair .
looks like u are facing SDA but a bit diffrend than a normal SDS.. mine still can go into download mode with blank product name..
If product name is blank in download mode then you got sudden death, consider a phone as a brick. Nothing will help, including repartitioning.
You need to contact service centre.
I'll check it in a minute, but if it is bricked, will any service center actually help me seeing as it's rooted and all?

AFAIK if it's sudden death then it's not possible to detect root and other modified things, or in other words - nobody has money to prove that you have been using unofficial firmware .

Ahhhh, well that is handy then
In terms of a service centre, will samsung have a list of them somewhere so I can find one near me?
So I contacted samsung and they gave me the link to book into a service centre etc, but I just realised that when I try to go into recovery mode, the CWM recovery logo comes up before going back to bootloop. Is there any way to get rid of that so that my root is completely untraceable?

If you can't flash anything with Odin (stock software) then you're screwed. Eventually you can try to enter recovery and flash "eraser" of recovery, but this requires working recovery... So if you actually can enter recovery then you can also flash anything, which will literally delete everything.
In other case, no, no way. But if you're lucky enough you may break it just by leaving your phone on for some hours in bootloop, haha.

Is there any way to wipe it with magnets or anything? hahah I'm clutching at straws now, but otherwise I'm just left with an expensive paperweight so I'm trying to find anything I can

To be honest think twice before physically crashing your internal memory, as it may void your warranty at all.
I'd try flashing stock firmware through odin, if it doesn't work I'd try flashing anything through recovery. If both of these methods fail just leave your phone in bootloop and hope that it'll automatically destroy everything... :laugh:
Seriously though, you can either physically destroy internal memory or leave it in bootloop and hope for the best, eventually send them device in current status. Up to you, because you won't have a possibility to do anything else.

If I send it back to them as it is now it'll take them about 20 seconds I reckon before they see the CWM logo, realise its rooted and send it straight back, so I dont know what I'm gonna do hahah
