I have a Samsung Galaxy S2 SCH-R760.
What happened: Tried to update phone from standard IceCreamSandwich to Jelly Bean via Samsung provided SimpleUpgradeTool. Very new to flashing phones, forgot to check model number, first attempt failed. Eventually got the right one (difficult to do with my model apparently), and the mobile network wouldn't work. Was told to reset APN, could not find it anywhere in the system.
Got fed up and decided to revert back to original OS, which failed. Waited overnight (it was late) with the phone off. Found the right file (just going to go back to Jelly Bean), however whenever I attempted to get into recovery mode it told me there was not enough power and to charge the phone. Phone was plugged in, this happened a couple of times. Now after the phone has been plugged in for well over 3 hours I cannot get the phone to power on or anything, it absolutely will not respond. Attempted to use Kies, will not recognize my phone model and is waiting for the phone to be connected anyway. When plugged in (trying/using various different cords) I have a little faint blue light flashing in the top left corner of the phone (not the phone screen).
The phone has been in excellent condition up until this point, and I have little reason to believe that my battery just suddenly went 100% bad after showing no signs of decay in recent weeks. Any suggestions?
How did you try to revert? But kind of sounds like it might be hard bricked. If you can't get get into Download mode by Vol Down and Power and it isn't charging not even sure if this would work: http://forum.xda-developers.com/galaxy-s2/general/ref-usb-jig-faq-frequently-questions-t1402286
But unless you try another battery or something like that jig, and it does not power up to any screen, then your only hope would be a JTAG service. I recommend these guys:

Just tried to use the samsung quicktool program and just install the old OS back onto the phone.

I'm not familiar with the QuickTool. Why not use Odin? It's the preferred method for most popular Samsung phones.

Hi guys, not entirely sure if this is in the correct place but I believe it is, sorry if it is not.
Today i plugged my Samsung S2 into the laptop and Kies proceeded to connect and everything seemed fine. I then saw that there was a firmware update, I then proceeded to download and try to install it, this failed some how and it then tried to do an emergency recovery which also failed. So i turned the phone on and off again and the screen that appeared was a phone..warning triangle...computer.
I tried plugging it back up but Kies was not connecting with it anymore, and everything i have search about it talks about something called "Odin" and rooting, neither of which i have tried or read about in any great depth.
I contemplated going up to the local shop and seeing if they could do anything although i think they would be just as good as me.
Before today i hadn't updated any firmware at all since getting the phone in January, i have just been using it straight out the box. So my question is, can i fix it? And how would i go about fixing it?
Im am in the UK and on the O2 network if that is any use?

Can you try turning the phone off, then simultaneously press the Down Volume Key + Home Button + Power Button, keeping same depressed for about 10 seconds to see if the phone will boot and enter Download mode?
If it does, then you may be able to use ODIN as per this thread http://forum.xda-developers.com/showthread.php?t=1075278 to properly reload an image.
Better send it to your near Samsung service center to have it replaced if it still under warranty.
if download mode works then jus flash stock rom via odin...an kies dosnt update the device if the space on main drive(ex--c drive )dosnt hav enough space i think around 30 or 60gb is required...an if u wan to update via kies only then flash old stock rom an connect to kies hope all goes well...if none work then try the jig (search on forums)well i made my own jig tht jus pushs the phone to dounload mode........cheeeeerz
Hi, I've been browsing the forums for people's attempts to fix a problem. At first the phone just turned off and I was unable to turn it on because it was stuck in a boot loop. The rom I had running was an ICS stock rom from hk. During this time i was still able to get into download mode but unable to enter recovery. I have tried many times to get to recovery and then tried to flash with several stock roms too. Upon failing around 10 times I moved on to a custom rom.
This one here:
http://forum.xda-developers.com/galaxy-s2/help/guide-26-12-flash-stock-firmware-rom-t2365701
The Jelly bean one here.
Upon failing from this too and unable to do anything but reset the phone and try again. I managed to turn it off... but now unable to turn it on in any way or get into download mode or recovery.
Is there anything I can try to do to get the phone to be working? What can I do?
Try a jig but understand it's very unlikely to get you into download mode. Service centre or local mobile repair shop for diagnosis (I also doubt it will be JTAG'able).
Edit - Also, search for KingRat's 'jump start' method where you try & boot the phone with just the charger/without the battery.

Don't loose hope mate...
Try remove battery and insert charger (optional)...
Press voldown+home+power button then let someone (your mother, father, brother, sister, neighbor or friends) insert the battery for you while still pressing those 3 keys...
I hope it will enter to download mode again...and report back please...
Try to use an other battery, my original one is fuked up, it does nothing.
I bought a new one and it works
I tried plugging my charger to the phone and pressing the 3 buttons and then having someone plug the battery in for me, still wouldn't start up. Also tried it with another battery i have on hand, also no luck.
You know what the options are then. Ignore people making ridiculous suggestions which don't work. My aim is to be honest with people, tell them the truth, and have them either get their phones fixed or replaced as quickly as possible in this situation (let's face it, nobody likes to be without a phone), rather than fill them with false hope & waste their time.
I think I fried my mobo while trying to flash it cause it does head up the phone without showing anything. I am going to order parts on ebay. I got this confirmed by someone at a shop near where I live, however they won't replace the mobo for me even if i do find a working one.
=) luckily this isn't my phone but my dad's who works at home and doesn't mind using an OLD OLD flip phone just for calls for the time being.
Side question, even if i replace the mobo and I get it booted but I still get stuck in the boot screen loop and unable to flash to any stock roms what can I do?
If you replace the motherboard you should fix it without further problems. New motherboard = new NAND, no more bootloop - unless you flash again & the flash is bad; you can't mitigate the risk of a bad flash, you can only do all the sensible things like making sure you're using a PC with reliable USB ports, that you're flashing the correct firmware for your device, that you're using an original Samsung USB cable. Basically, if you're careful, the risk with any given flash is very low.
So, fix the hardware problem, flash stock for your country/carrier once you've done that, and go from there.
So I rooted my s4 using towelroot and stupidly tried to install a custom recovery. First CWM then TWRP (not sure if this has anything to do with it, likely not?). Now it has no power, and wont charge...
Events leading up to the dead s4:
I "rebooted to recovery" and it brought me to the DOWNLOADING! screen instead of a recovery manager, I held down power and then it shut off and it turned back on again and brought me to another screen asking me to continue or boot normally.
I booted normally.
Then I deleted a few of the annoying apps that were preinstalled, nothing that was listed as essential to the Kernel/OS using Root App Delete. Finally I went to work with the battery dying, and it died on the way.
I tried to charge it the following morning and it would not charge. No LED light, no vibrate that usually happens. I left it alone with the battery out for 2 days, switching back to my s3. Tried again, still nothing.
Wont charge, computer wont recognize. Tried 3 different cables, a samsung charger and my asus tablet charger. Apparently it is a brick.
Thought it might be the USB port, and from a previous screen swap I performed, I still had the old USB assembly, so I swapped them, and it still will not respond. I even tried the older screen, nothing.
Anyone have the slightest clue what happened? I bought another battery to try, but doubt it will resolve the problem.

simple research you could have avoided all this....unless you have a MDK bootloader you CAN NOT install any custom recovery like TWRP of CWM without messing your phone up. Safestrap is your ONLY option. The link below is where you should have started your research. Most likely now you will have to try odin a clean image tar of your phone's firmware base

thank you. I know i messed up, have rooted/installed cfw on like 10 android phones but they always packaged root and unlocked the bootloader at once, which I never noticed.
Also, how can I connect the phone to odin if it wont connect to a PC? or charge for that matter

Re install your drivers then try again
Sent from my SCH-I545 using XDA Free mobile app
Sounds like a total brick to me. There are jtag services. I bought the equipment myself to jtag for a hard brick but my warranty company decided the replace my phone after all so I didn't have to use the equipment. Mine did the same exact thing. Wouldn't even get warm when plugged into the charger.
Hey all,
First i'd like to tell my phone was 'working' as it was able to go to download mode.
Im not really an expert, but when I used Google to find a solution for my error I read about using Odin.
(In case you need the error, I will try to edit the thread and add this asap!)
I followed a tutorial about using Odin and tried to get my phone up back and running.
I downloaded the following file for my Samsung J5:
sammobile.com/firmwares/galaxy-j5/SM-J500FN/PHN/download/J500FNXXS1BQG3/181971/
After using the Odin software it somehow got interrupted while installing. (cable came loose I guess, I heard the connect/disconnect sound shortly after each other)
Also I noticed there was a small red text on the screen complaining about the available size on the phone.
Even though the phone installation was interrupted, the phone was still able to get into download mode.
Next up, I decided to place a micro SD card to get extra storage space and retried the Odin process. The final result was a "PASS" (see screenshot)
i.imgur.com/WzFJLaQ.jpg
After the update was done 'succesfully' the phone screen immediately turned to black.
There were no signs of life anymore, not even accessing boot mode / recovery mode no nothing.
I've bought an USB JIG, but sadly also with the JIG I had no luck.
Is there any way to get my phone back and running? or can anyone give me some advice?
I really hope someone can help me out!
Sounds like a hard brick ?
This happens when you try to upgrade or downgrade, some devices don´t allow this or the firmware is not matching.
Pull out battery if it is removable for some minutes then try normal method, if not....
Here the correct method to do a jig by your own or maybe it´s better to buy one (it´s not expensive) to made sure that is correctly made http://www.instructables.com/id/USB-JIG-to-give-life-to-your-Bricked-mobile/
Also you can try with Smart Switch https://youtu.be/y8AZyalTf5Y

Can you check your pm's?
I recently purchased two new VS988 for an elderly friend of mine who loves his current G6 and was worried about LG getting out of the phone business. Trying to get the phones all set up for him I tried running the OTA updates which kept failing. After the OTA update process failed a dozen times or more I decided to try using the Windows VZW update utility. Finally, after a dozen tries the VZW utility finally managed to DL the FW to my computer but when it tried to install the FW it booted the phone into FW Update Mode and then failed to install. I have tried all of the listed methods of button presses to reboot the phone into any other mode but it always comes back to FW update mode. This morning I learned about the LGUP program and have given that a try and it stops at 4% with an error message that says "Error: 0x700A, ManipulateBootPT Failed"
I'm not sure what else to try. I'm using the cable that came in the box and a USB port on the back of my computer.
Any help/advice will be greatly appreciated.
Maybe turn of recovery mode
How am I supposed to do that? No matter what buttons I try pressing when rebooting the phone it always comes back into FW Update Mode. I tried running the recovery process and the Verizon updater program and that had the same problem.

I don't recommend advice from that guy
The problem your having is stuck in download mode.
As long as you're not connected to a PC via USB and actively transferring a firmware file, you should be able to force shutdown by removing the battery and placing it back in (if possible) or pressing and holding Power for about 20 seconds. Then power on again normally.

Hey, did my information help?
Unfortunately nothing has worked I just ended up with two bricked phones. Thankfully they were just supposed to be back up phones for somebody that is unlikely to need them and can afford buying another replacement if something ever actually does happen to his primary. He has a lot of accessibility issues in a really prefers having the the buttons on the back of the phone so he doesn't keep turning it off accidentally.

If your android was stuck in recovery mode (as i know it), you could of just factory reset right?
forgive me it's been a couple of months since I bothered messing around with them but I believe it's not a generic recovery mode you know where you've got those four text options at the top you know and the Android with the exclamation point coming out of its chest but instead it's a firmware update mode. No amount of software tools or button key presses and we'll get the phones to do anything else. Both phones are dead right now cuz I just wanted to confirm what I was telling you whatever they managed to charge up later I will make sure what I'm saying is correct and I will let you know otherwise
If this is the screen you see, then i regret to inform you that your phone might have been bricked the entire time and you couldn't save it (unless you get new firmware for you device and install it). Trust me i had this experience before.
This is what I get. I try running the the Verizon LG update utility on the computer and after it reaches 11% or something like that it fails

Welp, my last geuss at this is that the previous owner got something like a virus to prevent the firmware update to continue. i've only worked with lg phones a few times, but those phones where very old (2008) and did not run android
Thanks for trying. I've given up and my friend didn't even get upset about it. Whatever went wrong happened when I tried to manually update them because the OTA kept failing. If he buys any more backups in the future I'll find him something a little more recent.
