So my friend's phone died during a software update which completely messed up his phone. I thought it would be a simple fix, no problem, but there is hardly any valid information out there that can help me (due to a lot of dead links). Here's the issue:
The phone (SPH-M950 btw) loads the initial "Samsung" image on the screen. Then it goes away and starts to boot up with a blank screen. My computer recognizes the device until a couple seconds late the phone restarts itself and continues this boot loop. I cant boot into the stock Android Recovery but I can boot into Download Mode. I've tried for hours to flash all kinds of ROMS with Oden but, despite the fact that Oden says everything worked, it still continues the boot loop.
If possible I would like to get the OS to work again without losing any data. If not then I would at least like to get the phone to return to it's OOB state so it's at least functional.
Help please?

Did you try to access the recovery mode after you flashed anything?
Try it and check whether it works. Then try to format /system /data and /cache (internal data will be lost) and then reflash stock rom via Odin.
Then try again.

I forgot to talk about accessing recovery mode. All that happens an Android logo pops up and starts to look like it's loading the recovery os but then the phone just reboots again and continues to do the boot loop. Nothing changed no matter what custom recovery I flashed.
I would have no problem if I could just get into the recovery menu but that's my biggest obstacle.

Hello,
I have a S3 which is stuck in a bootloop at the samsung logo.
when i turn it on it shows the logo for some seconds then the screen goes black and the logo re-appears.
i can not boot into recovery mode, but download mode is working without a problem every time.
i tried flashing stock firmwares with odin and also tried kies emergency firmware recovery. the flashing always went without any problem, but it had effect. whatever i try, i am never able to boot into recovery and still stuck in the bootloop.
in some tries after flashing the screen just shows the samsung logo forever, but after rebooting it once it then is stuck in a bootloop again (shows the logo - screen goes black - shows the logo...)
i also tried flashing TWRP and CWM via odin, but again i can never boot into recovery mode.
what should i try next?
thx alot for any helpful comment

You can Try this:
1.) Pull out battery
2.) Put it in again
3.) Press Vol up + home + power
4.) When the Samsung Logo appears let it off
I think you press the Buttons too long.
I had the same problem!

i really tried everything, it's not working. btw with i am stuck at the very first image, where it says "samsung Galaxy sII GT-I9300".
i dont think it's just the way i press the buttons because i can reach it on my s1 and s2 without a problem, it's just not working on this device.
could some setting like "nand erase all" in odin help? in other threads there is sometimes mentioned that the internal file system might be screwed up and in those cases a simple odin reflash does not help anymore...
Nand erase will usually hard brick it. Try the rescue firmware from general forum, sticky thread. Follow the guide exactly as it includes a pit file.

thx, but i already did that (multiple times) and flashing via odin always succeeds. then the phone reboots and is stuck at the first samsung galaxy s.. screen. twice i managed somehow to get into recovery (after flashing cwm6) but it then randomly rebooted.
and i dont think that the power button is stuck because when i am in download mode it is perfectly fine it never reboots itself unexpectedly.
Had a similar issue on my tab2 p3100. It all happened when I tried flashing a custom recovery from rom manager.
A bad flash of anything related to recovery or bootloader could be a probable cause.
I remember a knowledge share on one of the threads describing this issue and as mentioned on it all I had to do is this:
1) switch off the device and plug in the charger. This would light up the display showing you the charging status. The status has to show if at least your bootloader part of the phone is fine.
2) plug out the charger and immediately press the three buttons (home + vol up + power) get into recovery mode. This step has to work and help you get to recovery mode.
***Note : the interval within which this step has to be performed is too short since the display would turn off immediately as soon as you plug out the charger. A bit tricky too so you have to be fast. If this misses getting you into recovery, pull out the battery and put it back again. Repeat step1 and 2 again.
3) upon successfully getting into recovery, perform wipe data, cache and select reboot phone from option available on recovery again.
Allow the device to boot. This could take a while since you have performed a data wipe and may prompt for first time set up.
I was able to restore functionality on my tab after these steps and like ppl learn from their mistakes, I then learnt that recoveries and bootloaders are things that needs to be done with a pc only.
Worth a try if you have tried other alternatives and found no go. may help. Who knows..
all the best.
thats also not working. i tried to get into recovery since two days now...
i also tried the steps from this thread: http://forum.xda-developers.com/galaxy-s3/help/solved-pit-bricked-dead-problem-gt-t2535367
but again, after i flash the cf-root (successfully) the phone does neither boot into recovery by itself nor can i do it by hand...
its crazy... in download mode i can see the model number (GT-I9300) and i thought as long as the model number is there and i can enter download mode there should be a way to recover the device.
but i cannot think of anything to try that i have not done yet
If the rescue firmware didn't help then it looks like the emmc chip is damaged.

is there a way to make certain of this? how can i tell if it is really a hardware damage and not just a software brick?
i just dont want to let the phone go, it looks still so shiny
is there anything else that could cause the phone not booting into recovery mode after flashing custom recoveries?

Same here, still didn't found how to fix it.. I guess our motherboard just died..
Howewer I have a solution that "almost" worked for me.
Get a stock firmware in odin and turn on Nand erase and T-flash
When it's done phone reboots and you'll see just "Downloading..." mode when you turn it on.
Then got to Kies and Select firmware recovery...
Enter s/n and model name and wait for the flash to complete.
With it , I got past boot logo and actually booted into android but the phone crashed because I guess I have a memory issue..
Well , gl. If you don't find anything else helpful , try going with this method..
My phone is a verzon note 2 on deodox 4.3 with twrp recovery. The phone only boots to teamwin logo and flickers on and off. my computer will not recognize my phone either at this point.This is what happened. Ive been having some 4g lte loss and unstable wifi issues to i decided to do a factoty reset. when i rebooted into recovery i was stuck at the twrp logo and it would constantly bootloop the twrp logo.. I restarted my phone and did a factory reset from under the general setting. At that point it rebooted int the twrp but continued to just stay at the logo and would not go into recovery. I pulled the battery and restarted the phone but from that point on it would only boot into the twrp logo and stay there. I can get into download mode but my pc (win7) no longer recognizes the phone so i cant attempt to fix this in odin. Im not sure what to do to get this phone to work properly at this point.

My guess is that when you rooted with CASUAL, it changed the Samsung device driver on your computer and you need to reinstall the Samsung driver to get the computer to recognize the phone again in download mode.
Underneath step 7 of section 1b on Droidstyle's restore guide, he discusses issue with CASUAL replacing the Samsung driver... and he gives a link to Jeremy Loper's fix... "If odin no longer recognizes your device, most likely Casual killed the driver for odin!! follow this tutorial for restoring the driver: http://www.youtube.com/watch?v=zzghcV8HVVk"
Once the computer recognizes the phone again, you should be able to use ODIN to restore back to 4.1.2 so you can root/unlock again with CASUAL. After you get the phone restored with Odin, I would recommend booting into Stock Recovery and wiping cache/doing factory reset before running Casual again... this would enure you are starting over with a totally clean slate.
If the above doesn't work, then here's a thread where I tried to help someone else who couldn't get their computer to recognize the phone.... maybe some of those ideas will help - http://forum.xda-developers.com/showthread.php?p=55833998
Good luck!!
1 step forward two steps back. I got my pc /odin to recognizes my note 2(changed usb cords). Then tried to odin back to stock 4.1.2. At first odin kept saying (odin not responding) and would ask to close the program,after several attemps i final got it to flash the 4.1.2 file. When i flashed the file and was at the point where it reboots, it would not get past the samsung note 2 logo and continued to flicker and not boot up even when i tried to put it into download mode like it said to in this thread. http://forum.xda-developers.com/showthread.php?t=2024207. When i tried to reflash the file it failed. when i attempted again it just hangs at setupconnection. Tried again and it failed. Btw thanks for the help mattnmag.
Got it working! i simply forgot to place the sch-i605 pit. into the pit section of odin when i flashed the 4.1.2 rom.
Similar problems
I was running AllianceROM 26. My phone had been spontaneously rebooting for a bit recently. Today, it started to spontaneously reboot again, but this time, it never got past the Galaxy Note 2 screen. After pulling the battery, I tried to boot into TWRP. It just hangs on the twrp boot screen for a few minutes but never goes into twrp.
I figured I would try taking it back to stock. So, I used ODIN to try and put 4.1.2 on it and a new PIT file. That appeared to work fine. I got no errors in ODIN. However, I still cannot get this thing to get past these boot screens, either the Galaxy Note 2 one or TWRP when I try that there. I have tried this twice now, once with re-partition checked and another time with re-partition unchecked (saw conflicting instructions on that so I figured I would try it both ways). I still am not getting past the boot screen.
Any help or ideas are appreciated as right now, my phone appears to be bricked and I am out of ideas.
so what was the solution to the teamwin flashing on and off after a factory reset? this is certainly not a solution, having to reflash the phone...
This is the problem I am having with my Samsung Galaxy Note 3 (SM-N900P). This problem just popped up out of the blue on a stock ROM a few days ago and nothing I have tried has gotten close to fixing the issue
Description:
a) The boot sequence repeats in a loop with no more sound. The phone would reboot at the Sprint splash screen
What I've done so far:
a) Pulled the battery and depleted the capacitors
b) Installed TWRP and did a complete wipe
c) Tried installing a custom ROM to see if the issue persisted. ROMs failed to install as /system was being sketchy (at times it was reporting 0MB for partition and then an actual value after repair). When I managed to get a ROM to install still stuck in the boot loop
d) Used Odin to do a full restore to a stock NC5 ROM. The phone got up to initial configuration page and then rebooted, now only gets to the Samsung splash screen before rebooting
Items that I can get into:
Recovery mode
Download mode
I have a 30 second video of it rebooting but cannot post it currently due to the forum rules
Question:
Is this issue fixable or is it a sign of internal memory failure?
Try an older version of TWRP, i.e. 2.8.5.0
Or, try a different recovery.
I'm not sure that it will work, but it's worth a try.
Good luck!

I didn't notice that but I just installed TWRP 2.8.0.0 through Odin (like a few minutes ago). Phone actually managed to get to the stock recovery image config screen and was working as long as the cable was still attached to the computer.
As soon as I removed the cable it went straight back to the boot loop

Here is what you need to do. First pull battery, reinstall. If you can boot into twrp recovery, fine wipe everything i.e. caches, system, data, etc. If you are on a stock recovery do a factory reset. Pull battery, reinstall and boot into download mode.
NOW let's go to work. First use odin to flash stock NC5 tar. Chances are it will bootloop, STOP !!!! don't panic. Just reflash with odin again. The second time it should take. Remember that your device is setting up for first time use. This will take 3-5 minutes, sitting at the Samsung logo. Since didn't list the most important thing which is what OS you where on where the device Borked, or what you where doing with the device when it Borked. I'm going to assume it was on 4.4.4 and you tried to downgrade to 4.4.2 NC5. In which case a bootloop on the first bootup after a downgrade is normal, you have to flash twice to reset the bootloader. For more info click on rom flashing basics in my signature. Enjoy !!!
Problem solved. I started getting suspicious when the phone would boot up with the charging cable attached to the computer today
The issue was an aftermarket Mugen Power battery that developed a fault. Put the stock battery back in and problem resolved
Thanks for the help guys
Ok, so something seems to have gone very wrong with flashing my phone :S
I managed to get recovery working yesterday, and followed the steps in this thread, http://forum.xda-developers.com/xperia-z2/general/4-4-4-creating-rooted-update-package-t2933155 , to create a pre-rooted 5.0.2 image. I put it on the external SD card, booted into recovery and installed the flashable zip, then used flashtool to flash with the instructions (though I also cleared Appslog, Cache and Data to get a fresh install). This went fine and everything appeared to be ok. I then tried to get the Xposed Alpha installed, but after that whenever the phone was rebooting it just hung if trying to boot to Android. I tried re-flashing with Flashtool, but still got the same issue. Would boot fine the first time, but then any restart it would just hang and crash out. Tried clearing the cache from recovery, but no difference.
So today, I went into recovery, re-installed the flashable.zip, then powered off the phone and flashed using flashtool, just as I had yesterday. Now though, my phone wont boot. It shows the Sony logo, then a blank screen, then restarts. Even worse, it will no longer boot into recovery. I hold the volume down button when the LED shows, nothing. I try holding the volume down button all the way through several bootloops, nothing.
I've tried to re-flash using flashtool which goes through the process ok, I can hold the volume down button and connect the cable once its in the process of rebooting, and it goes through all the process fine. It then powers off as expected and I can just disconnect and power on the phone. But it's still stuck in the bootloop and I don't have TWRP recovery.
Is there anything I can do to get my Z2 working?
Update - Re ran flashtool, this time not excluding system, only Partition. It now gets a little further, going to "Powered by Android" and giving the purple wavy lines, but after a minute or so it just hangs and restarts again. And still no recovery sadly....
I think I've got it sorted...
Used Flashboot again to do a flash, excluding System and Partition. This time the phone does boot up normally. The downside being that my root was gone. Despite my flashing a pre-rooted image, it seemed to just put a stock image on. And my recovery is still mysteriously gone.
In the end, just to get things completely back to a stable/stock starting point for later on, I ran a repair from PC Companion. Seems I was in the none rooted position anyway so figured I'd get myself to a more certain position. At least this way I can wait for someone to come up with a root for 5.0.2 so I can root and get recovery back.
i had my amaze repaired (power IC, bad data cable caused it to not charge or even boot up or go in bootloader). Now within 30 seconds off booting up it used to restart. and i cant get into the recovery( shows logo and powers off when going into recovery from bootloader). i cleared the cache from bootloader and its now stuck at boot animation( not boot logo) and wont boot completely. before clearing cache after logo it used to show 4ext recovery boot screen then screen off, now it just shows logo and screen off. really need help i got this phone fixed after 1 year. im s-off and running any 4.4.4 rom (dont remember which rom, i think pacman rom)
so basically i can get into bootloader and use fastboot commands (no adb, authorized device). cant do anything else on the phone. is there a way to fix the phone?

reflashed recovery for the 4th time and it worked. it said the cache partition is corrupt. formatted it. phone works now. updating apps caused system ui stopped working error. going to flash other roms.

Glad you got your phone working--your persistence paid off.
Be sure to make a backup before flashing other ROM's.
