Help! Galaxy S2 won't boot (Phone--!--PC)

Hey, i am new here i used to get helps lot in this forum but now i am facing a problem that i didn't found a solution for it yet..
first off i tried to change from android 2.3.6 to 2.3.5 (Arabic support) using Odin v1.83 when i put the .tar file into PDA then i run it. gave me failed and the phone won't work again when i restarted it gave me result are like this : Phone--!--PC
please help me i cannot do anything.. i tried to remove the battery using usb cable go to recovery mode,,, download mode but nothing it keep appearing even it i turned off the phone just in one click to power button it appear again.. i am going to crazy and the phone has warranty expired please is there anyway to solve this problem?

I don't know if your phone is the same, but with my Nexus if stuck in bootloop I can plug the usb cable in and use adb to enter command "adb reboot bootloader" and get to fastboot and flash the stock images. Maybe you can try something like that. That's why I love the nexus I thought I bricked it a couple times but I always got back to stock images. or if you have a cwm restore you can get to that once in fastboot.

Thanks for your reply! but where i can find stock images?? and can i make it without formatting everything on it? plus when i did that i wasn't have the sd card inside it and without a sim card also

i found on the web that i need to install default kernel.. i did that and put it to bootloader in Odin and the operation succeed but now i am facing looping on Samsung logo with yellow triangle ... see the picture.. it always loop can't do anything tried recovery mode download mode but nothing.. is there any fast solution please? i beg you guys please

Try to wipe everything trough recovery, and flash another rom.

Just google for Heimdall recovery

Does Heimdall perform anything different than Odin?

try to install leaked original rom ics for gs2. i try it and yellow triangle is out

I have the same problem, can some1 help?
I try using kies to fix the problem but the gt-p3110 is not supported when u go to Firmware upgrade and initilazation, put in the serial number from the back of your battery, then the tablet model and when u click ok is telling you that your model is not supported.
Can some1 tell me how to do it using Odin , even with complete wipe, or stock ROM.
Thx and please reply

"Firmware Upgrade encountered an issue..." = that´s the black screen of death. Download mode is enabled in this situation automaticly, no need to boot into downloadmode.
Uninstall Kies first! Maybe that´s why Odin failed! Maybe some Kies prozess running in the background.
Start Odin as Administrator,
Connect your tabelt to your PC (yes, with black screen of death!) - Odin will show "Added"
Now flash a Stockrom for your device
Safed your Tab

i did that with odin, untill it show'd pass but when i turn it on is the same
i loaded the file in the pda section,auto reboot and f.reset time boxes were checked
i used this http://www.hotfile.com/dl/182607797/b61e3af/P3110XXCLK7_P3110OXACLK7_BTU.zip.html from here http://forum.xda-developers.com/showthread.php?p=35095146 , the uk link
if u have a working method can you please tell me and live a link and how to do it?
thanks and please reply

maybe bad download? redownload a rom for your deivce e.g. from www.samsung-updates.com

Just did that , but is the same, I use Odin 3.07
Any more ideas?
Thanks

I notice this thread has been dead for some time. However, I am also in search of a possible solution to this as a colleague of mine passed one of these tablets on to me in the hope I could get some use out of it. It is in the same state as the previous posters claim, 'firmware encountered a problem.....'. Obviously I'm in a different situation as I did not buy this thing with my own money, not will I lose out if it is beyond repair. But I'm interested to solve this problem none the less.
So, so far I have attempted to flash a philztouch recovery using Odin which was unsuccessful and I have also tried to flash several compatible ROMs. All of which have failed, Odin confirming each time that the attempts were unsuccessful. I have read that the tablet in this state auto unlocks the bootloader, so I have ruled out that as a sticking point. I have read that flashing ROMs potentially won't work either as the corruption of the firmware is seated too deeply for this to have any effect. I know a possible solution is to try flash a new kernel as this goes a lot deeper, but this can be risky, however, like I mentioned above is not an issue for me as I have nothing to lose. Does anyone have any pointers on how to flash a new kernel? Surely there is a way to remove the corrupted firmware completely? I have to admit this is beyond the realm of anything I have used Odin for in the past. Also, I am more than aware some of my understanding may be incorrect so feel free to correct me. Any help would be greatly appreciated, even if it's just to point me in the right direction or towards some reference material which could shed some light on this particular problem.
Thanks in advance.

GT N8000 Bricked Urgent Help

OK, Ive been without my note for a whole day and been researching wht to do nonstop
What happened to me was that, since i had updated to official kitkat, i soon developed a taste for lollipop, and went on to try out different ROMs and finally settled on to crDroid
So it was one of those days where everything was going well until the note stopped opening apps for like a minute then showd a black screen and then all of a sudden restarted
Since this was a Sammy i thought it would get back up again.... But no, even a 5 minute didnt wake this beast up, it remained stuck at the boot logo, i.e, Samasung Galaxy Note 10.1
Im like ok ill go on do a factory reset and wipe cache and all, upon trying to accesss the recovery after the boot logo the recovery kinda opens then gets back at boot logo, a black screen shows up then turns on to be a full brightness black screen for a sec then goes back
I can access the download mode and can odin things but they fail every single time.
I have tried to odin a recovery and a stock recovery so far and they show a nand write error
i also have tried to PIT but they get stuck at get PIT for mapping
I have also tried all versions of odin tried changing a USB Port and the wire with no success
So is there any hope for my NOTE??
Please i need help its urgent

is it rooted ?
i have the same problem from 2 months and i am finally got that i must replace the motherboard

Sounds like its written its last, flash is dead.

Since you are able to enter in download mode there is hope. Trying to flash recovery which doesn't match the firmware version will always fail. So, try flashing some of the base firmwares which will return everything to stock. I was in your situation few months ago and managed to flash Android Revolution HD 4.4.2 after first flashing stock firmware via odin. I got my 4.4.2 base firmware from "sammobile.com", firmware section (sorry i don't have enough posts for using links).

I remember i tried flashing TWRP for GT N8000 and i also tried Philz then CWM all for GT N8000
I also tried flashing base rom but it gives NAND write fail

Nand write fail can mean damaged PIT or the actual nand memory is damaged and needs a new motherboard .

flash with pit file
found these pit files for the device.
you can flash the pit file for GT-N8000 in odin
don't forget to repartition, it's a very delicate situation, you don't want to mess it up, before going to this, you should confirm if the size are same. you wont like to flash a 16gb to 32gb partition.

same problem for me, this did not work, still write error

I have a similar problem. Everything is stuck. I am tryingo to go back to stock, but if I try to connect (via Odin, Heimdall, fastbot or adb sideload) i can't.
Is there any advice?
Thanks

nope not yet

I'm early ???
So it turned out that my AMAZING tablet had its storage device corrupted... I. E I exceeded the read write count

Similar problem Bricked N8005
I bought my N8005 (variant of N8000 but phone is disabled just data 3G is available) in 2012. I rooted it once and used custom rom for a while but last year installed official stock ROM again. Yesterday I started a game called "zombidle" (possibly this is an unnecessary info) and tablet restarted itself but stuck on "samsung" logo.
I tried to enter recovery mode but it always restarted and cannot enter recovery mode.
Tried to install different versions of CWM, Philz and TWRP recovery using odin but it always FAILed when NANDwrite started. Tried odin 1.85, 1.87, 3.07, 3.09, 3.12 but all same.
I tried to install same stock ROM but always FAILed.
Then I tried to install a custom rom but it failed too.
I read about bad pit files. Searched internet and found some pit files but nothing changed, FAILed at same point.
Did I finished all solutions?
Should I take it to the doctor?
Any sugesstions?
Thanks in advance.
Edit: Today I took it to the Samsung doctors. They said that; this is a mainboard issue and mainboard needs to be changed. That will be over 400TL (TL=Turkish Lira). Device is still in markets and new N8005 is 1300TL (i think this is also expensive. Because new Samsung Galaxy Tab S2 T817 32GB 9.7" is 1900TL in my country).
Does it worth to fix? Any opinions? Can I fix it myself somehow?

Nand write fail probable defunct memory.

PLEASE HELP ME with galaxy S2 SHW-M250K Boot problem

Please guys, my galaxy S2 SHW-M20K (Korean) is in trouble.
I bought it from a 2nd hand shop , and it was runing Android 4.1.2 Jelly Bean (rooted stock rom). I had no problem with it till today when I tried to install "CWM Recovery", After searching the web i found a post with two files that supposedly could do the task. These files are:
1. CWM_KT_M250K.tar
2. Tegrak-Kernel-Build-39-for-SHW-M250K-UE18.tar
Using Odin, I triedd the first file but it couldn't work, and the phone could not boot so i downloaded the "rooted factory firmware" and flashed the phone. Everything was ok. Later I tried the second file. Again the phone could not boot and stuck at the logo with a yellow triangle. After waiting for about 5 minutes I tried to shut it down by pressing the power button it did'nt respond. (Now this is a point that I regret), I removed the battery as a way of forcing to turn it off.
Now my phone cannot boot. It doesn't respond to power button, neither does it allow me to enter recovery mode nor download mode. But When i connect to the charger or pc, it start charging and keeps cutting off the charging frequently. But it only allows me to enter download mode when connected to pc. When I tried to flash the "rooted factory firmware", again, the flashing goes smoothly but when the phone starts rebooting it fails as if there is a power cut. Is my battery damaged? Can someone give me a guide on how to fix it?
I need your help gus, I am not an expert in the rootings and roms,
Pardon My English. It's a foreign language to me.

As u mentioned, I think that your phone has gone to a Soft Brick. I don't know much about the Korean build, so Google it to solve the Soft Brick. Try flashing the stock rom via odin but I don't recommend it since it may cause your phone to be hard bricked if not done properly.
So go to the service centre, you'll get more help there

I thank you sir for responding to this. From what you have said, I think the best decision is to take it to Samsung service center. (For I have tried to google it but I couldn't get a solution). I would also like to know if it is repairable, and about the cost, is it worth repairing or should I think of buying a new phone?
I am stranded.

[Q] Can I root a n8010 stuck in odin bootloop (tried everything else )

Hi all..or anyone out there
I have had the seemingly strange bootloop problem on my stock note N8010...which stuck on the dreaded "samsung galaxy note 10.1" and only has odin feature working. (and no factory reset options because I think the poor old tab is crammed to bursting with apps, files and cache and so had a meltdown) poor thing.
so anyway I check these sites of techie wonder and wisdom and followed every logical option..starting with the simple ones
first ran power down and tried to boot up (x3) with no joy, then take apart the tablet to disconnect / reconnect the battery and boot up (x3) still no change.
So went and got the firmware from samwares (both jelly bean and kitkat) to then flash through odin....tried and failed first because of dodgy cable, but the then got a new one...and joy of joys (at first) odin recognised my tab and the firmware flashed across with pass..but then auto rebooted straight back into the dreaded samsung 10.1 again....so tried different versions of odins... and tried other global n8010 firmware...but funnily and frustratingly then all fully download and pass in odin (and the andoid logo and green download status bar on the tablet seems to shown that downloading is and has fully taken place.... but the darn thing still wont boot up past the samsung galaxy note 10.1
Sadly coming to the ends of my tether (of so many nearly there false hopes, high and lows) and very little cash to send it to the Sami tech bods doesnt help matter....I then read and tried the (supposed) last resort pit file/firmware option...first with kitkat (as apparently that worked for someone somewhere) and then tried with jelly bean..again each time itAlways passes in odin.... but auto reboots into the dreaded bootloop logo .... to haunt and torment me.. Aaaaagh!!!!.....I would not mind if it said action failed (for once) like some others seem to experiencet...but it always passes in ODIN????
So.....have come to the semi ignorant conclusion it is either the bootloader section of the tablet or the original software that is messed up or some internal hardware component has a fault.
but was wondering if there is anthing left to try...or would it potentially be possible or worth trying to root a tablet in this condition?
As although I have not ventured into the wild worlds of rooting.....I am now pretty confident of messing with this tablets mind..and have little to lose...so any further ideas and help would be great.

Exact same here. Never flashed, totally stock N8010. My wife hadn't used it for a couple of weeks. So she grabs it again and it was off. booted to nothing but the boot logo. Nothing worked except Download mode.
Flashing stock roms has Odin reporting success, but it still won't boot up. Trying re-Partition does give a fail as soon as I press start.
And we aren't alone. It appears there are quite a few of these cases. I have no idea how to solve this.
I have done a bit of rom flashing on my old galaxy S (the first one) and bootloaders and such usually were included in a ROM. Rooting was done with Recovery or an app and I think it was also possible with adb, IIRC (it's been a while).
It's my wife's Note and she's starting to scope out mini iPads...

Same problem with GT-N8010
I am also having the same problem.
I tried to upload a new ROM via ODIN. All was successful from the ODIN app (PASSED). but stuck on the boot screen. Power and Vol up does not work (it appears to but then crashes out to the boot screen again) so no way to do a hard factory reset.
Volume down/power does work and allows you to get to Odin mode. but as above, uploading a new ROM does not seem to work.
This is an un-rooted GT-N8010 with the stock ROM when I purchased it back in 2013 I believe.
Come on guys, give us some ideas.
Thanks
Gene

Sounds like wrong model firmware flashed as that's the usual bootloop problem .
Try Odin firmware flash wait to passed then remove battery for a short while and replace and try recovery mode .

In my case there is no incompatible firmware issue... The tablet just stopped working one morning and that was that.
Can't comment on the other posters though.

My wife's the same. Never done anything to it. No idea how to remove the battery. I let the battery run down once, then recharged it, made no difference.
That was before trying to flash the new firmware. My Note says N8010 on the back, it says so in the download mode. I got a firmware from SamMobile for the N8010. Don't know what else I can do.
