OK, let me start by saying I am NOT getting the bootloader, I am NOT getting stuck on a startup screen, and I am NOT new to loading HTC ROMS (but I am new to the titan - former owner of Hermes). With that out of the way....
I bricked my Titan - It won't startup at all. Plugging it into the USB port generates a red LED and nothing on the screen. The only USB activitey seen on the computer is the HTC USB modem (no other communciation appears to be possible - no activesycn, no response to ROM updates etc.
This is the order of the bricking
1. Started with Default Verizon install (less than 4 days old)
2 unlocked with olipro 1.20
3 attempted install of Sprint 3.35 update to get radio (failed and rebooted device at 11%)
4. attempted intall of radio 3.27 (sucessful)
5. installed NexVision 3.35 cooked rom
6. ran into some stability with the rom (phone remained "Unactivated") and reverted back to ruu_signed_verizon stock ROM
7. Booted OK (phoen remained "unactivated"
8. reattempted install of sprint 3.35 (thinking rom instability was due to radio version) device rebooted itself at 11% and failed.
9. installed olipro 2.4 thinking it might circumvent the 11% reboot issue on Sprint ROM.(appeared sucessfull) phone never came back after that.
Now I'm dead in the water... Pulled the battery, Tried a hard reset (2 softkeys under screen/press soft reset) - no change in the device.
are there any secrets to unbricking a Titan?
Starting with the default Verizon ROM, updating to olipro 1.20
Hold off for a little bit, at the moment there is no unbrick, but ImCoKeMaN and jocky are working on this. Your phone now is booting into Qualcomm download mode and it is recoverable. It's just a matter of a patched loader to get a new spl on it...
thank (fingers crossed)... even tried the relocker by ImCoKeMan and it's not detecing the device either...
Time to be patient and wait for CoKeMan to come to the rescue.
just to make sure...
when you tried a hard reset... sometimes people dont know to hold the soft keys for a couple seconds (this is my experience anyway)
jsut for kicks try this again... press and hold the 2 soft keys, press reset button, keep soft keys held down, release reset button, wait a couple seconds then release the soft keys.
Hmmm I remember someone else with a similar problem not too long ago. He thought he had bricked the phone too and was getting the same red led when he plugged it in, but nothing else. His problem was that he had a defective battery. If you could get your hands on a spare battery I'd say try that...I'm not 100% sure it's the battery, and if it's not then I hope cokeman comes through for you...but if you can check that out, I definitely would.

Was just about to post the same thing, red LED is definately an indicator of a battery issue, could be defective or just totally dead. If you unplug the battery and reinsert it and then plug in the usb charger without turning it on do you get a green LED? If so I would say battery is 100% discharged and wait for it to charge (I have had this happen). Otherwise if it is still red after that I would say replace the battery (I had this happen on my first titan, it was doa due to defective battery).

Exactly, all the roms downloaded from HTC recommend having at least a 50% charged battery.
Yup, battery was at 99% before the upgrades. with or without the battery in it reacts the same, with or without the USB in it reacts the same.
I left it plugged in all night, no change.
Solved (but not really)
Since the phone was brand new, Verizon techs took it back as a "faulty phone"... thankfully the Red LED to them means "bad battery" too and when they replaced the battery and it didn't fix itself they exchanged the phone.
It's good that your phone was replaced, but to all the naysayers in this thread, you don't know what you're talking about. If the bootloader won't come up when you reset while holding power and camera, then the SPL is gone and the phone is booting into download mode. If you want to check this, connect to windows, it should find a new device, a qualcom debug port in download mode (you might need a driver for this).
The issue is being worked on and a solution will be found.
wow, i didn't (i did-but not reallly) know that it was really really possible to brick your phone, i thought there would more or less always b e a way out. pretty scary!

Ok well then I guess you could call me a naysayer then. And I assure you I am no dummy myself, in fact, I'm a Computer Engineer and work with embedded systems alllll day long. I don't doubt your knowledge about the bootloader and the SPL, but before you doubt MY knowledge explain this one to me. Stock battery, no bootloader, no nothing...just red LED. Replaced battery and all of a sudden phone boots...both normally and when forced into the bootloader.
I have the exact same problem. I don't remember exactly how it happened, but was similar scenario to previous posts. I believe I was trying to get the 3.35 radio installed for use with dcd's 3.0.1 kitchen, although I can't be positive.
QPST shows that it is seeing a Qualcomm device in download mode. Here is the exact model# it displays:
Q/QCP-XXX (Download)
Hope this info is useful to those that don't have a titan stuck in this mode.
Yep, that is a brick currently, but a method to fix it is being attempted.
Basically the phone has a dual core cpu with 1 core running the spl, and wince; and the other runs the oemsbl, qcsbl, and amss (the radio). Your spl is missing so the operating system core is doing nothing. However the phone side is still up and running. (this is mostly theory)
So we need to have a patched bootstrap to send in download mode (notice qpst software download actually sends over a bootstrap 7500.hex file found in your qpst bin directory) which will load the spl back into the correct areas of memory. I don't believe we can jump to it because we are on the wrong core.
Do you know which address range the SPL sits in memory?
JTAG ?????

Hey Shadow, I think you are correct, and also possibly do you think that JTAGing it would work ? Grad the image from a good one and load it into a dead one. I do not yet have one to take apart yet to try, but if i get a bad one to take apart I might just get it.
It would be great to see this issue resolved as this same problem happened to me last nite and the "friendly" folks at Bell Mobility took one look at the phone and told me it was water damage. I've had the 6800 for about 20 days and it has not been close to water. Anyways, that's besides the point. I look forward to seeing some kind of resolution to the matter....thanks!
Do you see same in QPST ?

I am not going to take mine apart to look for it, but i am sure there is a JTAG port inside these as there is every other I have seen.
Yesterday my battery died half way through playing a game (not entirely unexpected, I'd been playing on my phone quite a bit that day and it still lasted 22-23 hours), I connected the charger that came with the phone and left it to charge while I got on with some uni work.
The phone vibrated to tell me the charge was complete so I disconnected the charger and turned the phone on as usual. After the samsung galaxy S2 splash screen, the screen lock appears and when I move it there are several error messages saying that various applications have had to stop (the main one seems to be TwLauncher but when I force close it, many others also force close). This continues for several seconds until the phone decides to restart itself and repeats the process ad infinitum until I can shut down the phone (I can manage this by not trying to get rid of the screen lock and just holding the power button until the menu appears).
I've had this phone a week (one of those days being today where it did not work at all) so it's still well within the return period but I was wondering if there is an obvious fix that I'm missing.
If not, I'll be ringing Samsung on Monday (I have coursework due for friday so I'll be devoting my samsung office hours time to that) and if they can't give me an easy fix I'll be ringing the place I bought it from and asking for an exchange.
So, has anyone else had similar issues and managed a simple fix?
Bump, I take it everyone else's phone is working then?
Giving this another bump in the hopes there's someone with a simple solution.
I don't want to have send my phone off and wait for the place to get stock.
there have been 2 firmware releases from samsung in the last couple of days, i assume you are running the latest firmware?
I can't even get the phone to stay on long enough for Kies to recognise it. It keeps restarting. Even when it was working I couldn't get Kies to work with it properly (I couldn't copy the contacts from the phone to the computer).
It's running the firmware it came with, but I can't check which version it is.
I was going to try flashing the new firmware via ODIN but I've been busy with coursework. Is this likely to solve the issue or will I just be giving the retailers ammo to reject my return?

Basic FAQs on the SGS1 forum mostly apply to SGS2 .Worth a look there before Google .

Well, first of all, I should start by greeting the community, as this is my first post. So, yeah, hey everybody, been reading the forum for quite a while now, and it's been of a great help
Now, to the problem - this morning I noticed that my sgs2 had turned itself off. I didn't suspect the phone to be bricked or something as this happens from time to time when using custom roms. I tried turning it back on, it booted up, showed my kernels logo (DorimanX, not sure for the version though), so I put my phone in my pocket. After half an hour or so, I wanted to make a call, but I noticed that my sgs2 still hadn't booted up. So I tried restarting my phone using the power button, but instead of restarting it just turned off and I hadn't been able to turn it on since - it's bricked
I've heard of phones getting bricked while flashing a new rom or kernel, but never had I thought it could happen on simply booting up...
I did some research on bricked SGS2 and here's what I have done so far:
I've tried booting up in recovery/download modes, but that doesnt work.
I've tried soft/hard resetting my phone - still no luck.
I've also tried making an USB Jig, didn't work though. I'm not quite sure if my self-made jig works in the first place, as I did mess up the micro usb connector pretty bad while soldering resistors to pins. I'll try that one again with a different jack later and will keep you updated on weather it worked or not.
So, my question is, if my second try at making a USB Jig fails, is JTagging my only chance on reviving the phone? I guess that a MOBO change would probably help.
Another question is, if JTagging is my only chance, wouldn't it be easyer to just replace the bricked NAND chip? Then again, even though I have all kinds of soldering equipment accessible and also have the skills to do it, I have no idea where it's located on the mobo... Some info on that would also be much appreciated.
I havent flashed a new rom for quite a while now, last time I did it was when the latest version of Resurrection Remix was released.
My CPU wasn't overclocked - it was underclocked to 1GHz.
I was using DorimanX kernel.
Thanks in advance

I guess the battery is charging, as it heats up, but I don't see the charging animation. Also my PC won't see that a USB divice of any kind is connected.

order an usb jig and try. If it does not work send it to a repair center
Very similar happened to me a couple of days ago. Sgs2 crashed and wouldn't boot. I was also running dorimanx kernel, under clocked at 1ghz.
Originally I managed to get to download mode (not recovery mode). Kernels wouldn't flash via odin. I also tried using samsung kies to flash stock without success.
I tried the solution for nand bricked phones in this forum, however, this appears to have hard bricked the phone, since it failed to flash and now the phone does nothing (other than get hot when it is plugged in.) Nothing shows on screen. The PC does not recognise the device.
None of the threads I've read seem to offer a solution to this - any ideas? I guess I need to try a service centre, but thought I'd mention since I had same configuration as jankanolv, which of course may just be a coincidence...

Sounds familliar, lol. Anyways, did you use USB Jig to get to download mode? Or you just managed to boot it up on it's own?
I am really confused right now, because I'm pretty sure this can't be a hard brick as nothing has went wrong while flashing something on the device - it just bricked itself...
I've just get in the forum a few minutes ago only to find somoene with this symptoms, and i wasn't in here for too long and voilá...
Since yesterday my SGII, with no problems to this date, went in reboot mode for a few times.
I have no clue what is going on, but im sure something is.
i'll wait to see if theres anyone else complaining about it.
cheers
Hmm... Looks like a lot of people are getting this "brick" lately.
Maybe we all used some kind of app that bricked the phone on bootup?
Well, I tried to make another Jig, didn't work... This time though, I screwed my resitors up...
Another thing - is it really relevant to have exactly 301kOhm resistance between pins 4 and 5? As far as I know, it just kind of short circuits some pins on MOBO, which tells the phone to boot up in download mode. But I might be wrong...
Btw, sorry for the double post.
Same Problem
Hi,
I just face the same problem today,
now my S2 not working and just heat up.
this only happened after the original update done to my S2 - Android 4.1.2 - 2 days ago.
any help please
heat up....near the rear camera heat up?
Sent from the little guy
Mine gets hot near the camera. Nothing shows on screen.
In answer to jankanolv's questions:
- originally I could get to download mode via pressing home/power/volume down. (Not any more following failed flash). I've not tried a USB jig.
- my crash which started the situation occurred while I was listening to tune in radio pro app.
Well guys....near camera heating + no boot/dl/recovery = claim warranty saying that you factory reset the phone, 4.0.4 was laggy.
Sent from the little guy
was going to post a thread asking for help for what appears to be a similar problem
mine got stuck in a bootloop after pulling the battery, tried flashing new software in recovery then tried through odin but kept failing, now its bricked.
does nothing, wont go into either download or recovery mode so looks like its off to the service centre with it.

Yessss! good to know I'm not the only one facing this issue.
I posted a thread about this yesterday but it is all the way down in page 3 already:
http://forum.xda-developers.com/showthread.php?t=2192996
I tapped on the "sync" toggle on the notification shade and my phone just turned itself off.
Recovery and download mode were accessible though.
Thanks for the help.
I went to Samsung to get them to fix based on the factory reset while on stock 4.04 premise, but they were having none of it, and wanted to charge me to investigate the problem. Once out of warranty period, it seems it doesn't matter if their software can brick your phone!
I found a local phone fixing service in Hong Kong which investigated, diagnosed as a motherboard failure (which I suspect my problem genuinely was given how firmware flashes were failing), and replaced + fitted for 700hkd, (approx 90usd). The guy did it in front of me within 10 mins. "Andy Telecom" in Mongkok, on +852 9237 9237 in case someone else has the same issue locally.
Well, outta warranty...that's another story. You only get 1-2 years to brick your device
Glad you had it fixed for 90 bucks, some service centers charge around 150.
Sent from the little guy
Well, I finally managed to make a working USB Jig, tried it on Galaxy Ace, worked like a charm.
What confuses me right now, is that my sgs2 has drained all the battery, even though it was switched off for about 2 days. I'm charging the device right now, and I will keep you updated on weather my jig works..
Sorry for double-posting again on an old thread, just wanted to let you guys know - I took the phone to warranty service and they changed the mobo. I didn't have to pay anything and everything is working normally. Of course all data on sd card is now lost for good, lol.
So if you hard brick your device so badly it even won't respond to usb jig and you still have your warranty active, don't bother trying to revive your phone - just take it to warranty service
I guess they couldn't see the odin download count so they cant void my warranty, he he he ]
Hi there! Long time reader, first time poster (TL;DR below...but it should be a quick read anyways )
So I've been using this S2 of mine for almost 4 years now, haven't had any trouble (other than a couple of battery swaps). For the past 6 months or so I've been using CM 12.1 nightlies without issue.
The events:
- The other day, my phone froze (I wasn't using it when it froze, it was when I went to use it that I noticed...it was on the wifi selection screen if it matters), so I held the power button to shut it down, and when I powered it back up, it just froze at the Samsung boot screen (with the usual yellow triangle).
- At this point, I was able to reboot into download mode at will, but any attempt to boot to recovery just led to the freeze at the Samsung boot screen. Also, the phone would automatically reboot itself at this point any time I inserted the battery (I was of course putting the battery in and out trying everything I could).
- I would have reflashed from Odin at this point, but since I was away for a few days I just kept trying to reboot into recovery, to no avail. On one of these attempts (power+vol up+ home) it showed the Samsung boot screen, and then immediately shut down and I haven't been able to get anything onto the screen since
I'm now home, and I can't seem to fix it. If I plug the phone into a charger, the top half or so of the phone gets warm, and it also seems to get warm if it isn't plugged in and I try to power it up. I was thinking maybe the phone was maybe doing the same thing as before and just not showing anything on screen, but I blindly do the steps to get it into download mode, and Odin doesn't recognize anything (drivers are definitely installed). I have also tried other batteries, no luck.
Any ideas of what I might try? I'm willing to do anything. For the record nothing happened to the phone at all when this all happened (no dropping or water damage or anything, just my attempts at booting into recovery). Maybe I should try a jig? I'm also open to opening the phone if there's something I can do, though I don't have experience with this.
Thanks so much for any suggestions!
TL;DR: phone froze (running CM 12.1 nightly), held power to shut it down, and then consistently froze at the boot screen on any attempts to power it on. After a few attempts at booting into recovery (the phone would only freeze or enter download mode) the screen suddenly shut off and I haven't seen anything on it since no matter what I try. I can't think of anything that happened to the phone I'm open to any and all suggestions! Thanks
One sentence amongst your description stands out like a 'sore thumb'.....
That the device heats up towards the top when you attempt to charge it.......
Until you try a jig I can't be certain, but that heating coupled with a dead/unresponsive screen along with a lack of recovery and/or download modes (download mode is 'hardwired' into the device, and NOTHING should be able to corrupt it) are the primary symptoms of a failed motherboard.......
That is my opinion based on my experience in these forums and personal experience with a (now dead) S2 (one of two that I own).........
Get the jig just to be sure, but I'd be surprised if it had any effect.....sorry to be typing something you don't want to read, but you said it yourself, the device is 4 years old....it's been in service roughly twice as long as most smartphones, and they don't last forever....

Thanks dude! It's nice to have some idea of what happened. I am indeed very happy my phone has lasted me this long, and my friend is gonna give me an extra S2 she has anyways it seems so it's all good!
I'll try the jig and update here with the result (I ordered one online...will arrive in January sometime)...just in case anyone is curious.

Sorry it took me a while...the jig was in the post haha. It didn't do anything at all (no response when I plugged it in) so I think it's safe to say you were bang-on and the motherboard failed! Happily using a new S2 (with CM13.0 now ) on behalf of my friend though.
Thanks again.
Sounds familiar. Happened to me also due to failed cyanogenmod update (CM13). Only thing that works is download mode, so i'm not given up hope yet.
I can't post a link but google ''Apply Update Failure samsung galaxy s II'' there's a thread about this on the cyanogenmod forum.

oh mine was just straight up dead...no download mode or anything visible on the screen (and nothing to do with CM13 either)
hope you get yours sorted out! have you tried reflashing anything via Odin while in download mode?
Its hard to tell you and hard to accept. You can almost give up the hope, your NAND Chip is just what we call " wear-out ". In the most cases no write is possible anymore, the funny part is -> sometimes read is still fine. If that is the case: The system is booting and working, but saving just nothing. The NAND is frozen to its state before it broke.
At our local store, customers come to us with issues like " Factory Reset impossible ", "Can't delete my Files" "Can't create files". All these Devices have inaccessible NAND's and inaccessible Recovery. Only Bootloader is working, but as the NAND is broken, flashing doesn't change anything.

Hello all,
This past Saturday my Galaxy S8+ froze up and the display showed a bunch or discolored horizontal lines, then it shut down and went into a bootloop. I know this isn't an uncommon issue but it seems this usually happens from a botched upgrade/flash attempt. I've never attempted this and was just using my phone as normal. I have read through many bootloop threads and tried many of the troubleshooting steps, but I haven't had any success.
I'm starting to wonder if there's a hardware issue now. I'm hoping someone might have a new suggestion I could try, or point out any mistakes I made in my previous troubleshooting. I'm new here, so sorry if I left out any important details below, please let me know.
Thanks for helping!
Symptoms:
Phone is in a bootloop.
On occasion it comes out of the loop and displays some new phone setup menus (since I did a factory reset), but it crashes fairly quickly (and display gets distorted again) and re-enters the bootloop. It varies how far I can get into the new setup, before it crashes, but generally it's a matter of seconds.
On occasion, it comes out of the loop and displays a "System software not authorized by AT&T" message.
Attempts to fix:
Went into recovery*mode, wiped cache. Same results on reboot.
Went into recovery*mode, factory reset device. Same results on reboot.
Odin tool (3.13.1) and flashed lastest G955USQ8DTJ1_G955UOYN8DTJ1_VZW from sammobile. Device reached 32%, stayed for a while, then rebooted and back to bootloop.
Samsung Smart Switch, but then I discovered they neutered the app and it won't recover a device anymore.
Tried iMyFone Fixppo, but it failed to find latest FW for the device.
Phone details:
S8+ (SKU: SM-G955UZKV)
Bought it reburb 2 years ago.
It has never been rooted by me, so everything is stock.
Memory was close to full, but I still think I had a few GB left.
It was on VZW when bought, but I had it unlocked so I could use on AT&T.
In downloader mode, it says "Carrier: VZW", "Current Binary: Samsung Official", "FRP Lock: On", "Warranty Void: 0x0"

Hello all,
This past Saturday my Galaxy S8+ froze up and the display showed a bunch or discolored horizontal lines, then it shut down and went into a bootloop. I know this isn't an uncommon issue but it seems this usually happens from a botched upgrade/flash attempt. I've never attempted this and was just using my phone as normal. I have read through many bootloop threads and tried many of the troubleshooting steps, but I haven't had any success.
I'm starting to wonder if there's a hardware issue now. I'm hoping someone might have a new suggestion I could try, or point out any mistakes I made in my previous troubleshooting. I'm new here, so sorry if I left out any important details below, please let me know.
Thanks for helping!

Can you run graphics test from recovery mode? i guess something is overheating during boot. Can you put the device on a water/ice bag to lower the temp, and do factory reset ? as you said it displays some setup menus so its worth a shot

Seems to perform the graphics test fine. It cycles through all the graphics tests and then returns to the recovery menu.
I tossed the phone in the freezer for a few minutes and then tried a normal reboot. To my surprise it booted into the new phone setup menu, but this time it didn't crash right away. I was actually able to get through the complete setup and restore all my old apps (hooray google backups). In all, it probably worked for about 5 minutes before crashing again. I repeated the test, and verified that cooling it down does help.
So, great call! But what does that mean? Is there anyway to determine what is causing is this without a tearing it open?

Nice i guess it should be the processor thats heating.
You can find the location of the heatsink/thermal paste/process here (around 3:30 min mark)

The processor seems to be located below Bixby button.
You can also try gently pressing the spot where processor is located to seat it back, but am not sure how long it may stay. if the thermal paste is dry and not in contact with processor, you have to open the device.
Or you can take it to a local repair shop for some assistance.
