Going to try recall all the correct info as this has been a problem for almost 6 weeks. Initially 6 weeks back I was using cyanogenmod and noticed my S2 would only pick up as an unknown device on my PC, this was a damaged micro usb pin in the S2 causing this.
I tried flashing an early ICS rom using recovery and an SD card to see if the problem would go away but something went wrong and I got the kernel panic mode message. First time I've had a bad flash after countless flashes. I could go into download mode though. I took my S2 to get a new port put in. Got it back today but it seems in that time the battery has drained. At my first attempt today I tried putting it into download mode and got a message saying can't go into download mode battery low. Now all that happens is my S2 continually boots up to kernel panic mode goes off and back on to this message. I can't get it to show that battery low message again, Seems like my S2 isn't charging up the battery and is way flat, at the kernel panic message my PC and odin pick up the S2 momentarily so it seems the new port is okay.
I'm going to try charge the battery by other means and see if It will allow me back into download mode.....
PS haven't tried a jig but I reckon I'll still get the battery low message for download mode....

I guess you can boot in recovery, mount and storage format system, data, cache, factory reset, then try download mode.

So I went to my nearest mall to see if someone would charge my battery for me. Couldn't find anyone with a galaxy S2 till I walked into a Samsung store. Rep there took a battery out of the display S2 and let me leave with it! awesome....got into download mode, flashed stock kernel, bootloader and modem. Voila S2 is back to life after 6 weeks.
Thanks for the input guys, this forum is awesome!!!!!

[Q] I miss my Galaxy s2

ok this is shameful as my first post but well what the hey....
I purchased a samsung s2 in november, and tbh I love it to bits. last week in manchester we had a bit of a heatwave and upon getting home I put my phone on charge. after giving it a 30 min charge to sync to my computer I noticed my phone was stuck on the boot screen so I took out the battery and tried again. I did this a total of 11 times, and still stuck on the boot screen. so I went into the recovery settings and tried a soft reset, that did not work, so I did a factory reset in which it came up with could not mount E: I left it like that for an hour before taking it to the local mobile phone shop in denton named U&E connexions as I needed the phone for an emergency. two days later I get a call from the shop saying that there was nothing that they could do and for me to pick up the phone. Upon scouring the net for a solution I came across this forum and proceeded to find out about firmware flashing. so I initiated the download process on my sg2 and noticed the the binary was set to custom and that the download counter was showing the number 4. I found out that my warranty was void if the download counter shows any number, and contacted the shop who responded that there is nothing that they can do. so I purchased a mini usb jig to try and erase the download but to no avail. upon speaking with a couple of friends they said that it could possibly be a corrupt partition due to not being able to flash anything to the phone. Any help or advice would sincerely be appreciated.
I'm not experienced with this , but until some help comes I will share what I've tried .
I once messed with phone when flashing a ROM ,
so I did opened phone in download mode ( it run on download mode I don't know your phone can boot the download mode or not )
then connected to PC , ran odin , marked repartation and choosed a Pit file for my s2 ( by checking this you may wind up with bricked phone but for me it was already not working )
then I tried flashing a stock GingerBread ROM with PDA , PHONE and CSC files . aslo checked phone bootuploader update ( really Don't know why for but I checked it )
and clicked start ,it took its time , then, the mobile was back to life again .
anything you will do is on your responsibility . i just want to share what I did

I think you may check for different versions of Odin ,also be sure that pit file is choosen , and it is the right one and aslo the PDA , as in the link .
ok no luck still.. I'd just like to thank everyone for their help on this issue.
Not sure if you want to try this but perhaps you can try flashing to the original stock rom first?

if it boots up you again you can use triangle away to assist resetting the counter to 0.
it seems that my phone has the emmc bug. hence as to the corrupt nand rw permissions. I've tried flashing the stock rom using odin and heimdall and still no luck.
Gonna take my phone to carphone warehouse and tell them that my phone suffered the bug after doing a soft reset followed by factory reset. hopefully they dont notice the odin download count.
well they noticed the download count. is there anyway that I can kill the phone so that it does not show the download count or anything. I might be able to get a replacement that way. :s
Absolutely not. That falls under the "don't get us (XDA) in trouble" rule here.

use USB JIG simple :fingers-crossed:
I've tried the usb jig and it will only allow me to go into download mode, but the emmc bug will not allow me to downgrade the bootloader. or do any firmware flashing other than kernal flash.
hmm.. is you able to go into recovery mode if yes them flash SiyahKernel v3.3.2 and try to do system format if no then try Ultimate Kernel Cleaning Script
good luck :fingers-crossed:
edit and if you abe to go into recovery mode then select download mode from recovery (SiyahKernel) and try to flash rom again :
Thread closed
XDA does not condone fraud, and that's what you're discussing here. No more.

Help! S3 not booting. cannot access recovery or download mode

Hi. just a moment ago, while charging my phone. it works pretty fine. ( still playing my Sims freeplay ). after awhile, my phone could no longer boot. ( before it was hanged with my LED blinking ). it has turned to a full brick. i had no idea whats wrong. it was working fine a moment ago. i read online and it says it could possible be a hard brick. anyone could help me with this?
Is your phone rooted? What have you done thus far to try and boot it up again?
First things first: Pull the battery, put it back in, try and boot. If you still have nothing, try charging the phone - do you get the standard charging screen up? If you do, then let it charge for five minutes before trying again.
If you don't get the standard charging screen, I'm afraid the handset is likely to be broken. Others may have more ideas.
What have you altered that could of done this ?
ie. Have you changed the ROM,kernel,wiped anything just before this happened?
Sent from the man in Your attic.....
yes. before that. maybe 12 hours ago before i sleep, i flashed Omega rom V31 via CWM. and also did install some themes and kernel ( siyah kernel ). after that it was still working fine. until a moment ago.
Try taking battery out. Put it back and try to get recovery by pressing home,vol. Up, power together, if you could not get recovery from the menu. I'll see what happens when u post

Wondering if your kernel and ROM are mismatched. Do not know the ROM.it would save time if you could tell me. I'm CV tied up

I think if he can flash a firmware with odin doesn t matter what he had before. The phone just reflashes ando will bem ok. Theres not much to think about it. If not he assim a major problem, The boot isso damaged. Maybe with help of a jig he can restore it again.

Samsung S3 won't load passed boot screen?

Hi guys
I have done my basic research on all the forum room and can't find a answer to my problem.
I have Samsung S3 , I have not rooted or flash the device , I have not install any apps for the pass 2 months , for some reason today my device restarted and then got stuck on boot screen "Samsung Galaxy S3 GT-I9300" , am totally new to android and only had my device 9 months.
from all the basic searches I have done , I have try pressing vol key up + Home Key + power key) nothing happen
I tried : Switch off the device.
Press and hold Volume Up + Home Button + Power Key.
After 2-3 seconds, release the Power Key.
nothing happens here either this suppose to do a hard reset
I have taken the battery out , re-inserted the battery hold the power key for 10secs and I still don't get any where
each attemp I only get the boot screen the only luck I have had was by pressing the vol key down + home key + power key , i get the downloading Rom and this obviously does nothing as I can't get to the internet via wireless
please someone helpme the last person who posted this type of topic on this forum room did not get any replies.
I am sure I am not the only one who has experience this problem.
I am with three network if that makes any differents
thanks for your support.
Search 'sudden death' - you'll find more on it there
I has this problem with mine - I ended up taking it to Samsung for repair under warranty: it was a mother board replacement
it is however possible that you could fix it
Cn you get into download mode? (home + power + vol down)
if you can get to download mode ^^^ post above then all is well all you need to do is flash stock rom.
Getting into download mode is good news, Now plug your phone in to your computer, launch ODIN, and flash the correct stock firmware.
Thank you guys for your prompt reply , I have decided to take the device back to Car phone Warehouse as it is still under warrantee , I don't want to risk the manufacture guarantee. On this note I will like to salute all those geek's who have rooted their phones. :cyclops:

welcome in the emmc burned club - you are number ???
Flashing stock rom - chainfire tar - recovery tar - or whatever wont help you, i made a thread about it, no matter what you get "cant get pit" when you flash in odin
Sorry bR0 - seams like samsung made a MAJOR hardware error here - makes me thinking twice again before buying a sammy phone again, its a pitty cose it really is the nicest phone out there - maybe htc phones dont do this crap.. dont now
And since you haven't rooted or even flashed it, it proves just further that this is no "soft" problem but only faulty hardware !!!
Here is my link to tar files >http://forum.xda-developers.com/showthread.php?t=2019902
And just so you now, flashing a rom DONT void your guarantee, in EU at least, its a proven court judgment ! > http://forum.xda-developers.com/showthread.php?t=1998801
Urgent illegal advice required on 'sudden death'
Hi all /comrades
Four days ago I decided that I had to take Samsung Galaxy S3 to Carphone warehouse for repairs as the phone was still under manufacture warrantee , I did not wanted to go via the rooted / flashing my ROM . well guess what happen.
Carphone Warehouse Engineer total me the following and I quote " Please read notes , unfortunately handset returned unrepaired due to device rooted thought custom firmware, we have provided photo evidence. this is classed as Chargeable repair , please speak to one of the sales team to verify the cost of charge if you wish to take this ."
okay the photo screen that they gave me was of the one where you hold the volume button done + Home screen + power button and you get the Android stating its downloading on the top left side system status : custom and its this point he make out to me that I try to root or have rooted my phone.
as you all know I haven't got a clue on how to root or flash a phone never mind doing it.
I need your help , I am going to take Carphone Warehouse Ltd to Small courts to claim the cost of my phone and line rental back , How do I prove to the hight court that I actually did not root my device and Carphone Warehouse was trying to claim extra cash from me.
please all techie help me.

Stuck in the splash screen, no recovery mode, no download mode

Please any one can help me?
I have a Samsung Galaxy s2 GT-i9100G. I installed Android 4.2.1 via Odin. it worked fine, then i rooted it and also went fine.
My problem started when I tried to install GT-I9100G_LP7_ClockworkMod-Recovery_5.5.0.4 via odin. it seemed that it fionished ok. but after the reboot. the device stack in Samsung Galaxy SII GT-I900G, and I can't get to recovery mode nor the download mode using the key combination. it is just turning off and then stuck in the same splash screen.
Is that means my phone damaged??
can anyone please help me ????
Sometimes the screen well be black but your I download mode. I'm not at my computer but someone link or explain proper way do get in to download. Make sure pull battery before try download mode. Also connect Odin to see if your connected with black screen. Next time use mobile Odin to do recovery much safer.

Thank you so much for your reply, I appropriated that. I am still stuck there, could you please send me that link telling how to proper get in download mode??
Thank you.
Finally,I got rid of it. I don't know how exactly it is done, but anyway, I removed the battery for about 5 hours (Don't know if that makes sense), then I was able to get in the recovery mode only. I selected to wipe cache and then to factory reset but it didn't work. but after it rebooted I was able to get in the DOWNLOAD mode so easily. That's it, I just connected to the PC, then opened Odin, selected the official JB ROM, started to flash and .. VOALAA ... it works
Thanks guys ...
Special thanks to xxsicknessxx for not letting me throw my phone out of the window

Galaxy S2 GT-I9100 doesn't start , stuck at loading and reboot (PLEASE HELP)

Hi guys i'm new around here i had this problem with my s2 for a while now and tried to solve it myself but i haven't done such a great job and now my phone won't even start. I'll try to explain it as detailed as i can so you can understand .
So i rooted my s2 first time 2 years ago with the help of my friend (i don't remember the version of the android) and had this weird problem after 1 year i couldn't download any other apps because my memory was always full , so i decided to try another root maybe the problem will solve , so i rooted my phone to 5.1.1. Lollipop and everything was great for a week . Then the real chaos begin phone started to shut down randomly even with 80%+ battery and couldn't start it only if charged it , if the battery was 100% i could use the phone for 10 maybe 15 minutes and then again it would shut down , I used the phone like that for a couple of months but then it would shut down even when was charging so i decided to solve the problem (my friend didn't wanted to help me anymore) and started to search around the forum and on google for any solutions i found that i can unroot my phone to the stock official firmwave searched in the list for my version of build number but my build number (I9100XXLPS) is not matching with my region , tried the version of my region everything went alright until the phone rebooted . Now the phone is stuck at start up loading image and reboots itself after a while and does the same thing . I tried finding the good version of build number (I9100XXLPS) but i can't find any source of download .
Tell me guys what i am doing wrong and if you got any ideas how i could fix my phone please help :crying: :crying: :crying:
Thanks in advance.
Hi,
Try this guide if you haven't already:
[GUIDE][Troubleshoot a failed Odin flash]
Follow the guide carefully.
gsstudios
No worries, you must know from which region you have bought the Phone from so go to this link http://www.sammobile.com/firmwares/database/GT-I9100/ then signup and enter the region and download the firmware. And follow the link given by gsstudios. If you specifically want i9100XXLPS then get it from below link.. which is old version of IceCreamSandwich
