Hi Friends,
Everything was fine until my HD2 it turned off and since then ( two weeks ago) all it shows me when I turn it on is a black and white striped page( it goes to bootloader mode though and everything is fine,! it's not a hardware problem) . I've tried everything you name it,( Flashing via SD card, Using Mtty, Usin diff radios, and a buch of other stuff) I have the T-mobil insurance plan where I'll tell them the problem and they will send me a new phone, all I need to do is to get rid of that CotullaHSPL so that they wont find out that the phone has been messed with. So, My question is how do you recover to the original SPL, ((I've tried uninstalling the HSPL and it goes all the way to 100 but once the phone restarts and I go to bootloader it still shows me "CotullaHSPL"
Thanks,
Amir Najafi
its a reasonably common problem, , radio gets stuck, flashing appears to work but doesnt.
there are some out there threads about chilling it for half an hour, flashing certain test roms and the like, but there is no real answer to it. (not taht ive seen)
you could always try flashing a non tmous stock rom, (with a 51 radio) and hoping it takes enough to brick it completely, or go for the ten seconds in a microwave option, but ive always thoughtthe danger of exploding teh screen a bit much.

I have accidental on the phone worse comes to worse, I'll just do that, I've heard of freezing it for half an hour, but would that really work?!
lol, no idea, ,
i can imagine a scenario where corrupt software is overpowering the hardware so much that it is failing, and that cooling it may allow it to work past its thermal limits just long enough to flash, , , but its more like an old wives tale, an urban legend really, doing somethng just because someone else did it and it worked i think, luck of the draw. 1 - freeze phone - 2 - into bootloader - 3 - sacrifice chicken - 4 - flash hspl - 5 - recite ' arr ay dee eye ohh ' over and over - 6 - flash radio.... hehehe.

HA HA HA HA HA HA HA HA HA
That is the funniest sh*t I have heard all day.
Now as for the op's problem, if the phone feels hot after you try the flashing or after you leave it on for a while then you might have a processor that is slowly frying itself are causing itself to lose it's connections to the mother board because of the heat.
I know you said you tryiex everything but go get yourself a cheap 2GB SD card and format it even though it is new and the use it to put you ROM on e ergonomics time you try a ROM and try to flash via your SD card. If one ROM does not work delete it from the SD card download another and copy it to the SD card and try to flash it. One of them had got to eventually flash. Just be aware that if you flash any official ROM via SD card it will revert you back to SPL and you will have to reflash HSPL
I've tried the chilling thing btw, lol, it didnt work hahaha
So I picked up my VZW GS4 yesterday from Best Buy. I was out to dinner with my cousin, and the battery died (after a full day of very heavy usage). I tried to turn it back on to check something quickly, and when I did, the Samsung boot screen showed the unlocked bootloader symbol, with the words custom underneath it. I thought I was crazy and seeing things, so I rebooted again, and it was still there. Has anyone else run into this? I find it hard to believe that my bootloader just randomly unlocked itself.
I attached an image so people can tell me if that really is what it seems. Let me know if anyone has any idea what is going on.
Achievement unlocked!
Hey, less work for you in the end. (if you like to flash and rom that is)
I say Congrats!
Did you root and not flash the original kernel back on?

No. I had decided not to fiddle with anything until I decided how I liked the stock Touchwiz UI. I had the GNex before this, and messed with that to my hearts content, running clockworkmod recovery and cyanogenmod 10.1., but was waiting to try anything on this. That's why I'm confused, I've done absolutely nothing to it to customization wise. I haven't even set a wallpaper yet lol.
Maybe they shipped you a dev unit. Wouldn't be the first time lol

That's awesome, lucky you
If I got a dev edition, that is awesome :laugh:, saves me a lot of work down the road if I decide to run a custom rom. I swear I had rebooted it at least once (I feel like it might have been 2 or 3 times) prior to this, and don't remember it being there before. But now I'm second guessing myself - maybe I hadn't rebooted up to that point, or I did and just didn't notice it. That's what is throwing me off more than anything, I thought it just happened randomly, which I found hard to believe considering the amount of work that goes into finding a way to unlock a phone's bootloader.
So this leads me to a more important question. As I said earlier, I planned on keeping stock rom with Touchwiz for now (I know how many people feel about it, please don't give me 20 replies telling me how awful it is) but my main concern at this point is that I'm getting the bootloader unlocked symbol, and the word custom. When I go into settings and check the info on my phone, it tells me that device status is 'custom'. Now, correct me if I am wrong (but I'm fairly certain I'm not) I won't be able to get any OTA updates, because it will read my device as custom - and this is where I'm fairly certain something wonkey has happened, because I remember playing around in settings yesterday and seeing that it said device status 'official'. Basically, any speculation as to what the heck might happened (it isn't something any app could have done either, if that's even possible. I'm still setting up the device and barely have anything on there, and certainly not anything that would cause my phone to say custom) and any way at this point to get it back to device status official? I know a root method had just been released, but I wasn't sure about unroot.
That is not indicating an unlocked bootloader. Your phone has been rooted and the person that did it either did not odin back to the stock kernel or he flashed a custom recovery.

I have the same screen out if the box. So I decided to root and install cwm but it failed. Reading more they say it fails because the locked boot loader. So I'm confused
After rooting i flashed the stock kernel back. And that screen as seen in the first screenshot has not changed..
What do you think?

So I'd go with my phone being rooted, which doesn't really make sense unless someone at the Samsung Factory rooted it before sending it out, except I have a weird development. I pulled the sd card I bought (64GB Samsung Pro MicroSDXC Extreme Speed (UHS-1) Class 10 Memory Card), from Amazon directly, not a retailer on Amazon) turned it back on, and now I'm not getting the unlocked symbol and device status is back to official. I rebooted, turned it off, did a battery pull, and turned it back on, every combination of restarting the device I could think of, and every time it says official. I put the memory card back in, and at first it says official. Then I reboot, and it goes back to being unlocked and custom. Going to try formatting the SD card to see where that gets me, but at this point, it makes no sense to me.
I flashed back to the stock kernel after flashing the exploit one and I have the same screen on start up. Not sure why but it doesn't really bother me.

Since rooting I've randomly had that screen too. I just rebooted and didn't have it this time. No clue what's going on.
I tested the memory card theory, and that is in fact the problem. Tried formatting it, but it still causes my phone to read custom. Not sure if it is a faulty memory card, if the phone can't read this type of memory card (I know some devices can't read SDXC UHS-1 cards, but I thought I researched and the S4 should), or it's a software issue with the phone that needs patched. I'm leaning toward the last one, but got in touch with Amazon and they are sending me a replacement card. Will update once I get the new card. If anyone else is experiencing the same or similar issues, or has any idea what is going on, I would appreciate the input. Like I said before, it's not a major issue until I need to do an OTA update. At that point, worst case scenario, if the problem isn't fixed, I can always just pull the memory card. But don't want to go through the hassle if I can pinpoint the problem and fix it.

That's weird, my 32gb sandisk microsd doesn't effect it.
Have the same issue with the lock showing on bootscreen randomly. I haven't tried this morning but I think I am on something. Setup a link with foldermount, something from internal memory to the SD card. After a reboot and foldermount sets up the link at boot up, reboot and see if you get the lock /custom boot screen

I have the same issue and have another thread going on it. It said it once when reboot and device status changes from custom to original randomly in settings. Bought the phone brand new from Verizon yesterday.

Very odd. I get that now, but I rooted to get it.
Root has nothing to do with being unlocked though therefor I think it would do it bone stock like mine as well.

Okay... initially i was on Custom Rom Jellybam based on Jellybean 4.2.1 with Siyah Kernel V5 sync.
I want to upgrade to Kitkat 4.4
so i downloaded all the required files , made nandroid backup , reboot the phone and started transferring all ROM files into internal SD card Sdcard0
I am doing all this is Linux Mint..
It started transferring and got stuck 33.2%
so i removed the cable and try it again and this time again it stucked again
and my phone reboots automatically ..
Samsung logo main screen shows and loading starts but after completing loading bar .. it Freezes there and i cannot boot into recovery either..
SO on searching on goggle for solutions .. it states that i have to flash kernel again through ODIN again in order to access recovery to do Factory Reset..
SO i did the same flashed siyah kernel v4.1.5
it shows its successfully flashed BUT on reboot it shows Yellow triangle and freezes there and i still cannot access recovery and it also freezes on battery charge animation
So i again try to flash using ODIN this time again with siyah kernel 6.b5
and still same problem ,, so pull out battery and leave for 5 minutes and again boot phone in download mode and flash again using odin siyah kernel 6.0b5 and upon Reboot PHONE does not Boot.. I was literally Shocked and i try to pull out battery .. put back in and Try to charge but it shows no animation nor it is going in download mode.
Please HELP ..
Suggest me some ways because 1 year before I've replaced the motherboard due to same problem caused by factory reset in stock ICS rom when There was Hard Brick problem in Stock ICS roms..but it was in warranty so there was no problem but this time its out of warranty..
I didn't do anything wrong and still it got HARD BRICKED and still not have a clue what went wrong ??
No booting at all = nothing anyone here can do = replace motherboard or get a new phone (JTAG also very unlikely to work).

i know. this.. its TOO scary to hear this thing..
If anything is possible ?? Anything ??
i will give every info you needed..
And what exactly do you expect people here to suggest ? If the phone won't boot you can:-
*Try a jig (0.0000000001% chance of working, but try it if you like torturing yourself with false hope)
*Try a JTAG if the person who tries is prepared to do it on the basis of 'you only pay them if the JTAG is successful' (also 0.0000000001% chance of working, try this if you like torturing yourself with false hope even more)
*Replace the motherboard; 99.99% chance of successfully fixing the phone provided there's nothing else wrong hardware-wise

i'll go to samsung care tomorrow but i am still wondering what happened wrong as i did nothing wrong at all then still how it hardbricked ??
... probably you only need to flash a correct running ROM. Did you try to flash an original Samsung firmware? Did you wipe data before starting the new ROM? Otherwise there is a big chance for a bootloop.

the guide suggest to flash kernel so that i can wipe/data factory reset .. i tried that with odin but phone does not boot and freezes at Samsung logo when loading bar finishes... so i thought to flash stock ics rom but before doing that after flashing kernel again it reboot and hard bricked... and does not boot after all even in download mode..
So this happens after i flashed kernel 3rd time and i still have no clue why did it happened..
and customer care asks it would costs at least Rs.8,000 or $133 to replace a Motherboard.. which is too costly...
can anyone suggest me any other things.. ay alternatives ??
There are no other alternatives. Just because you refuse to accept reality doesn't make it anything less than reality.
And isn't it wonderful to see people still not reading threads & suggesting stuff that's impossible: 'probably you only need to flash a correct running ROM'. I mean, seriously ? The OP has already stated on multiple occasions that the phone will not boot. At all. How do you propose he flash 'a correct running rom' exactly ?

hahah... i know .. people are sometimes too lazy to read ..
I just need to know.. what's wrong happened so that it will not happen next time..
Honestly ? That's almost impossible to say. Best guesses based on what you've told us are you simply got a bad flash, which is a small possibility (maybe 1 in 10,000) with any given flash. Or, I've had a theory based on instances like this I've seen on here over the past two yrs which involves the connection between phone & PC being broken for a split second during the flash (possibly caused by less than reliable USB ports on the PC or something else intermittent on the PC side), but not long enough for the disconnection to 'register' on the PC-side like it normally does when an external device is disconnected (you get that exclamation sound & a notification that the device has been disconnected in your taskbar).
It doesn't sound like you did anything 'wrong', put it that way. So I'm not sure there's a whole lot you can do to avoid it in future. Unfortunately, that's the risk all of us take whenever we flash stuff to our phones; every single flash (even CWM ones) involves that small risk (due to the nature of the NAND; having a write abruptly interrupted partway through can 'scramble' it) and the only way you can mitigate that 100% is to not flash anything at all.
Well .. I've already seen several people claiming a 'hardbrick' while the phone was only stuck in a boot loop. Especially while flashing only boot.img / system.img (which the OP claimed) it's normally really hard to create a hardbrick. That was the reason to suggest to try to flash an original firmware.If instead the bootloader is messed up, there is not much to do ...

well I've got my s2 since past 1.7 years and nothing wrong has happened till date as I've flashed plenty of ROMS earlier.. its nothing new to me.. i am well known to these things..
i have exams from 1 month and s2 was creating problems such as freezes while scrolling in any application and automatic reboot from many time
i have no time to solve this during exams..
so i tried to solve this issue yesterday by upgrading to new ROM.. downloaded ROM files .. and ready to transfer to internal sd where copying stuck at 33% 2 times and at 2nd time from where main problem starts.. of freezing at bootscreen and then i trty to solve by flahsing new kernel thriugh ODIN where Hardbrick was TOTALLY UNEXPECTED.. as I've done this earlier time too but nothing happened wrong that time... i was literally surprised that it does not boot at all even i didn't done any mistakes at all & followed procedure.. even ODIN every time shows "Flash Successful"
i've attached screenshot of ODIN flashing.. so you can check for yourself..
May be there is a possibility of battery dying and phone cannot charge the battery ??
i've no spare battery to check .. so will go soon to care to check if its battery problem or not..

i totally understand what you wanted to say..
i now how to do these things.. i know the risks...
still don't know what happened wrong..
hey guys.. i just went to samsung care and they told me that PCB need to be replaced and it ill costs me INR 8,000 or $133.33 which is too expensive and i told them if any other thing can be done .. i see some videos in youtube stating DEAD or HARDBRCIKED S2 can be fixed by changing its POWER IC...
so i told them that thing then they told me that OFFICIALY only Motherbaord could be replaced however I can ask local reapir shops in my city whether they can replace POWER IC or any other such thing which will be cheap..
So i went to one of the Repair shop (MAIN one in my CITY) & i ask them .. after checking he said.. I'll check IF Repalcing POWER IC will solve the problem or not... otherwise Motherboard need to be replaced..
the cost of POWER IC replacement is INR 800 or $13.33
otherwsie
he'll replace the motherboard for INR 3000 or $ 30..
so i deposoited my Phone to him and will go again in 2 hours.. to check if POWER IC replacement will fix the problem or not..
I am wondering if it will be safe to do this from unofficial reapir centre whether he will not take orignal parts of my phone internals ? however every people go to his shop.... Motherboard repalcing by him costs only INR 3000 ($50) while officialy its INR 8000($133)..
why is there so much price difference..??
IF POWER IC replacement is good idea ??
i just don't want to be in another problem...
Probably a 2nd hand board. If it were me, I'd be replacing the whole board. I wouldn't want someone fartarsing around replacing individual components on a board that size no matter how competent they claim to be. But that's up to you/how much money you're prepared to spend.
As to whether what he's going to do (replacing an individual component) will definitely fix it, how do you expect us to possibly know that ? You're the one who's met the person who's going to fix your phone/we have absolutely no knowledge whatsoever of this person/their competencies. I know one thing though, in Australia, nobody who repairs Samsung phones for a living (I.E a commercial operation/business) would replace an individual component like that. Only 'spare timers' would do that.

well i ask a local official samsung mobile shop onwer whom we knows from years ... he said.. he is the main person in our city and everyone goes to him for repair... and he thinks he won't do such as thing..
SO i gave my phone to him..
and about power IC replacment there are some videos on youtube i checked before asking for POWER IC replacement....
so thought may be it'll work.. :/
hope for the best..

Unless you're one of the 'slow kids up the back', you'll know there is absolutely nothing anyone on a phone forum can do for a person like the OP who has a phone in that state. How do I know this ? Experience. I have seen thousands of examples on here exactly like this in 2 & a bit years. They all turn out the same whether you tell people straight up, or whether you stuff them around for two weeks trying stuff that has no chance of working.
And as it's turned out, I was absolutely correct in my initial post. I'm not a believer in having people try a bunch of stuff that has no chance whatsoever of working which builds up their hopes, only to have them end up disappointed when the 'stuff that had no chance of working in the first place' doesn't work (funnily enough ).
I'd much rather be honest with people from the outset, so they can either have their phone repaired & working again (or buy a new phone if people decide that's a better option) sooner rather than later, because I know what it's like to be without a (decent) phone for week/however long.
But you're not capable of comprehending this, are you ? You'd rather make your 2nd post on here a 'gob off' re: something you know absolutely nothing about.
So . the thing is IF POWER IC replacemet will fix the phone or not...i've done some googling and found that the POWER IC replacemet works for users..
If anyone here in this forum has tried this and successfuly saved his phone instead of replacing whole Motherboard.. ??

dude please if anything irritates you .. then i'm sorry..
i ts just its first time happened with me...s i am worried about my phone..
that's all :/
Hi all,
I'm new to this site and am kinda desperate.... I have trouble with my SGH-i717... whenever sim card is in, the device keeps rebooting.... I tried changing the whole sim card reader and no effect on the problem.... Device is now rooted (did it with odin) still no effect... I also tried sim card in other device and it works fine.... Running out of idea here and I'm kinda noob with this... Phone juste came out of warranty by the way and still stuck with 1 and a half year on my damm contract.. So I'll have to buy new phone or pay a 400$ penality for breaking contratc... dammit !!!!
:crying::crying::crying::crying:
Also, the phone has to be kept plugged in (to computer or wall plug) otherwise it keeps rebooting even when sim card is not in...
take a look at this thread if you haven't tried searching. I know you are new and probably looking for any fix. you cant panic here. your going to have to search and read.
in the thread I posted, or any thread, pay attention to the stats of some of the folks posting. you may pay attention to some of the more experienced folks.
I don't know some of the specifics as you did not mention. many factors come into play. you will see talk of what carrier..... it is important
what rom are you currently running or have installed?
how clean is your process of flashing?
how experience are you?
some in the thread are talking about modem......as one posted, "changing your modem is not going to fix problem", he is correct.
I have ran into many problems, only saw SIM message show when I had no SIM in phone. always the failsafe solution has been returning to stock and start over.
you would not be the first person to rush off and think, "im flashing my phone, look at me, im cool". doesn't work like that.
I have always been the more cautious one. I read and make sure I understand. I have all my files in place. heck, I have evan rehearsed the process.
sound stupid???
maybe so, but I have yet to have a problem I couldn't figure out.
could be a "fix permissions" issue
could be a "format system" issue
some developers have specific instruction for flashing their rom, any deviation could cause a myriad of problems.
again, look at experience levels of some of the posters.

keep us informed as people are reading, but you haven't given any specifics. you have told us what your problem is and what you need fixed, but didn't tell us how you got there.
need that if you want help
A little while ago, I'm not really sure when but my Wifi stopped working. If I tried to enable it, it would just grey out and look like it was enabling but eventually just returned to not on. I've tried flashing new kernals, new roms, new modems, and currently sitting on stock 2.3.4. I've factory reset, (without wiping sdcard data) on stock. Tried to see if there was an update (saw a post that had said if you update to 2.3.6 over the air it will fix wifi, however no such update exists) I've searched and searched and searched and I cannot seem to find any information regarding whats wrong or how to fix this.
Any input would be greatly appreciated, thank you.
It may be hardware failure. The normal test for hardware/firmware issues is to flash back to stock. You have tried everything that I would suggest for such an issue, except perhaps flashing the latest stock. However, wifi works on all stock versions, so... your troubleshooting steps point to likely hardware failure.
Actually, there is one more step I can suggest. Install a custom kernel, and re-format everything, including USB memory (internal sd card- be sure to back up anything you don't want to lose) and remove any external card. Mr-cook has some scripts that can make the process easier. This is a little more thorough than just erasing the data from the partitions. Then install the stock firmware, preferably the latest stock UCMD8.

Which of those scripts do you suggest using?

Hopefully, you have a basic understanding of memory partitioning. It is best to understand what you are doing, and not just follow someone else's recipe. That being said, you can use the first one, cook's rom wipe, which will format the system, preload, data, and cache partitions. If you also want to format the USB memory, you will need to do that from within recovery of the custom kernel: from the "mounts and storage" option, select "format /sdcard".
For installing the stock firmware, Odin3 v1.85 is recommended. Download the file from the Download Repository, extract the .tar.md5 file, and put that in the pda slot.
I actually have narrowed it down to a hardware issue, apparently I have the battery leaking issue. I've removed the corroded battery, and cleaned up the area which was effected. The phone still operates, however I still do not have Wifi. Is there something I can do to further fix the issue? I am missing a few tiny resistors in that area could they missing be the issue? I heard they just filtered the signal or something along those lines. What can I check or do before finally just needing a new mainboard.

I bought a phone cheap from the Swappa boneyard with a good screen but with the wifi not working to go with another phone I acquired which had a cracked screen but fully working main board. I combined the two into a fully working phone, and a phone with cracked screen and no wifi. The second phone sat in a box for a long time. Not too long ago, I read about the battery leaking issue, so I pulled that second phone apart and looked at the main board. Sure enough, the battery and the area around it was corroded. The phone was fully functioning except for the wifi.
I didn't play with it too much, but it looked to me like the battery was soldered onto the main board. Did you have to de-solder it to get it off? I believe that the battery is necessary for the wifi to work. I build electronics, but not on the miniature scale of a phone pcb. I have a professional soldering station, but I wouldn't attempt to work on a board like that myself. Unless you have the right equipment, and the experience to go with it...
I think you would need to replace the main board. You could try buying a phone with a broken screen that is otherwise working. It might be fairly cheap. But the I777 is getting old enough that it will be experiencing various kinds of failure, so it is a crap shoot.
I gave my original I777 to my wife, and bought one for myself on swappa over a year ago. The one I bought just went dark one day a few months ago. I don't know what part failed, but it was completely non-responsive, a true brick. My son had an I777 also, and he had cracked the screen, so I bought him an S4 for Christmas. I got his i777 and combined the main board with the good screen from my dead phone, to make a fully functioning phone. After setting that phone up and using it for a couple of weeks, one day the power switch failed. I'm still using that phone as my main phone, with gravity screen to overcome the failed power button, since I don't want to spend another $40 on it to get the power button replaced. The point of relating this is just to show how likely failures are.
Actually I just pulled it off, and cleaned the area. I've been reading that its suppose to keep the date and time, and I've also read that people don't actually know what its for. However I do know that since i pulled it my phone seems to heat up less. (It was getting rather hot) However wifi still does not work.
