[Q] Last hope: Desire S stuck in bootloader S-on

Hello,
My Desire S froze when updating Skype 2 weeks ago.
Removed battery. Phone stuck on HTC logo.
Went to bootloader for hard reset. When hard rest chosen phone freezes.
Went to recovery, phone starts recovery. Black screen, green icon. Then goes dark. Starts to vibrate 6-7 times. Then remains off. Battery out, battery in. Back to HTC logo again.
Laptop recognized phone when plugged in with fastboot mode. Under device manager (win 7) "HTC phone".
I bought the phone in Thailand, but am now in Philippines where there is no HTC repair center.
I managed to find RUU_Saga_HTC_Thailand_1.35.1113.2_Radio_20.28d.30.0805U_3805.04.02.01_M_release_183327_signed
Which matches my phone. However when trying to install the rom, the above app freezes on "restarting bootloader". I've left it there for over an hour.
I've tried ADB, but it's not picking up the phone.
I'm guessing either of the above can't load, as the phone is S-on.
But I cannot go S-off as I can't get the phone to boot, or any of the above software to find the phone. Again, windows is picking up that there's a HTC phone plugged in.
I've tried everything I know, and am at my wits end into thinking the phone is finished.
Can anyone help with something I may have overlooked, or have a suggestion to bring this back to life?
Thanks

It's most probably a hardware problem. There's a high chance that your phone's emmc chip is fried when u remove the battery. it's common in htc due to the phone design. My phone encountered same thing 2 weeks ago. sent for repair and they change the mainboard. I was lucky they ignored that my phone was S-on(warranty voided)

I was thinking hardware last week after everything was failing. But as it was still booting to fastloader, and being picked up via usb was holding out hope it might just be the s-on preventing me from putting on a new rom. And not a mainboard gone.
Flying back to Thailand for the warranty would cost the same as buying a new phone ...
If taking a battery out when a phone is frozen fries a mainboard on HTC ... I doubt I will buy one again.
Looking at Galaxy 2. But also having doubts due to wifi reports and overheating screen. Can't afford another dud smartphone.
If anyone's got anything else to get this thing up to see if the mainboard is indeed dead, or it's something else, do make a suggestion please!

I have same problem like this before and it's really pain in the a#$. Also, there is one HTC service center here in the Philippines, check it out on HTC site.

Yes, I've been in touch with HTC repair center in Manila via phone and email. I've been waiting for reply for over one week now!
I'm not in Manila, which would mean using fedex to send it up to them. Then bank transfer to pay for repair and shipping back.
If it is the Motherboard that's gone, all the above will probably cost more than a new phone
But I won't know until HTC Manila actually bother to reply!?!

so what was the Problem is it becoz of Skype?

no,this problem happens if you pull the battery out when installing apps
the emmc chip is probably dead,if so you need to send it for warranty or replace the emmc chip yourself

Well unfortunately, when updating the skype app, the phone froze. As in no buttons working, phone getting hot etc.
What else is there to do but take the battery out?
Either way, to have a "premium" phone like the HTC Desire S, burn out a chip, or indeed have a popular app causing it to brick etc is simply not good enough.
More over the support center refusing to reply back.
It simply means they've lost another customer.
The phone, when working, was wonderful. Looking at the Galaxy S 2 today, by all accounts a "better" phone, and it was sad. As, for me, the HTC Desire S was much more preferable.
Except of course for it's 6 week lifespan ... bad customer care etc

Just to bad that you did not bought it here. My phone died two months ago (used it only for a month), sent it to the store and they've sent it to service center (in Manila). Had to wait for a month for them to fix it. Motherboard issues I think. Good thing I still have warranty.

yeah,this is really bad
but mine has been working for 3months without any problem,& the customer support here is good
if you dont mind voiding the warranty you can buy a eMMC & replace it yourself
if you do so you wont get this problem again
refer this thread for more info

There is software "hard" reset option. Instead of pulling the battery out, press all hardware buttons together (vol up, vol down, power button) and phone will reboot. I said this many times before in many topics: never pull out your battery when the phone is on. I learned it the hard way.

Thanks kartkk. I wouldn't know where to begin with the physical replacement of the eMMC chip. Not even sure I can buy one around here.
I might call HTC Thailand and ask if I can send it to them via DHL or the like.

maybe you should ask HTC to write that in big red writing on the back of their batteries as they start to reach burn your finger stage when the phone freezes.
Or maybe copy Nokia's hardware which is near on indestructible.
Quite simply, I am not a phone tech person. I'm a simple end user.
I've not had a problem taking a battery out of other phones.
Again, if taking a battery out of a phone kills it when it freezes, then quite simply the phone is not good enough. Or, if it is likely to. Then, again, in big writing for simple folk like me, big red writing on the battery saying
"don't take this out, even if it starts to feel like it's going to melt"

BTW if anyone can point me to a step-by-step on how to determine if the eMMC chip is fried or not, I would appreciate it.
I read the above link. But don't know how to get to that stage!

Apologies I see he was connecting via adb-shell. I've tried connecting via adb and it's not seeing the phone....
Which I think is half the problem.

try searching on ebay for sandisk mmc (or any other brand just dont get the same one used on the DS)
its always dangerous to pull the power from any device which works like a pc even in a pc pulling the power out while the device is on can harm the hardware &/or software i know many people who damaged their pc from pulling the plug while its on

Best to my knowledge it was an emmc chip that was recommended to be replaced. Not an MMC.
While removing "power" abruptly from any electronic device is not recommend, one is sometimes left with no choice. Complete device freeze, no buttons working etc.
There is also a destine difference between a PC and a mobile phone. Though, it must be said from my point of view: today's Android phones, are very reminiscent of old windows 95/98 OS's in terms of stability and hardware issues.

Skyrocket randomly restarts and vibrates at 2 second intervals?

This has been happening for a few days now, the phone turns off and endlessly vibrates until I pull the battery, and then it does it again and again but it'll work for a few hours before it happens again... I've tried different roms but its still happening and it's getting very frustrating

does it do it on stock? And are you over clocked?

You mean like physically? Seems fine the phone just starts doing it randomly while it's just sitting on the bed. Right now it's not even turning on at all no matter what I try :/

...

Here is one example:

It's in download mode now, I'm going to try downloading stock Rogers ICS and see if the problem persists, if it does I still have 5 months of warranty so hopefully that'll be covered

Ok. You can try jamming on the power button repeatedly too...
Good luck!

Looks like the skyrocket's done for good.. I'm going to take it in to the store tomorrow but what do you think they'll say when they fix it and find out it's rooted?

no.
try this test, when it goes through the bootloop, keep the power button depressed w/out releasing it and see if it displays the same charactersistics as your bootloops, also count the seconds each situation has, if they are the same then the problem is the sticky power button

As posted earlier, http://forum.xda-developers.com/showthread.php?t=1801226
It's the power button that is messed up, hands-down.
Try and try and try and sooner or later you'll probably get it. I could care less about the phone as I have a replacement coming, but I wanted to get my data off of it.
Open up you're phone if you're comfortable and mess with the power button directly some, either you're going to fix it long enough to get your data or break it completely...doesn't really matter at this point.
Just put the battery in and right after the phone vibrates hold the power button and see how lucky you are at getting it to last the full 8+ seconds instead of the usual 2 before it reboots and vibrates.
Once you get it working, don't touch that *****. As gently as possible, set it down and get your USB in, turn on Mass USB and debugging and copy your stuff. Put the timeout to the max or download an app so you don't have to touch the power button ever and just touch the screen every once in awhile if you don't have an app. Don't forget to reset your flash counter and reflash stock ODIN if you're rooted or on anything custom (Use ADB to reboot through all this)
Honestly...I let my phone restart on its own for a total of like 8 hours (I didn't care and honestly hoped it burnt up or something and was completely fried) and I watched it for a good chunk of the time and it never booted up on its own. After I took it apart twice and beat the hell out of the power button a good while I finally got it to work.
Repeatedly mashing it after 'attempting' to clean it and then pulling the battery/reinserting and seeing if it worked is how I finally got mine.
Now it's just a paper weight till the new one comes.
Edit: I find it weird that a lot more of these problems are popping up. I noticed a bunch of threads on various sites towards the end of June that had popped up and now some are here too recently. I guess the Skyrocket's cheap-feeling Power Button is indeed...cheap.

It isn't the power button. I posted this problem months ago and took it in to a device center. It was actually a battery issue where it connects into the phone. The charge going into the phone doesn't stick, causing it to flicker power and thus restart constantly. They never ended up getting my old one to turn on and never saw it was rooted and what not. Ended up just giving me a refurbished one.

well if it never turns on, then its not the sticky power button problem, the sticky power button has a reboot symptom at a consistent interval

Alright, I will definitely try and try until the phone turns on before taking it into the store. This has actually been happening for a few days now but I didn't really care too much because I was really busy and I thought since it turns on after a few tries, I'll just take the files off and return it to stock later. Also, yesterday someone gave the suggestion of repeatedly jamming the power button and that actually worked twice but after that it never worked again.
Is it possible to remove the back and fix the power button without voiding the warranty (are there any stickers)?
EDIT: I have it disassembled right now, what exactly should I do to the power button? I tried clicking it a few times and blowing at it nd I put the battery in but still the same thing
EDIT 2: Umm what looks to be the litmus paper on the inside is red.. the phone has never come in contact with water so how is this possible..
EDIT 3: Every housing I've seen online (4-5) has a red square on the housing so I'm guessing it comes in red by default? Either way I'm taking it to Rogers right now, they said I could have a refurbished for 35 or I can just repair this one so I'm just going to repair it and hopefully the files will be preserved.
My only concern.. the phone running Juggernaut 5 right now LOL and the internal SD is full of rom zips and kernels so hopefully they don't look at that, or don't care. Once they repair the phone, what can they really do tho? Break it again nd send it back? haha

I would just fiddle with the power hoping for the best.
As far as your roms go, I doubt it'll be a problem. A) They're not going to get the phone to turn on anyway. They're probably just going to repair the button and reflash before they even check anything. Either way, like you said, the worst case is they find it but you already have your replacement...maybe they'll try charging you the phone, throw a hassle and offer to cancel your service and tell them to send you your "unwarranteed phone" and the button repair bill and they can have theirs back. I don't seem them getting you for it. All they might do is check the flash counter which probably hasn't been tripped if you didn't use a bad ODIN.

Flash counter is at 0, I checked when I managed to get into Download mode before it stopped working altogether. Juggernaut 5 is a rom for the Hercules (T989) and that's not the problem, I've used it before and I only flashed it after the problem started because I thought ICS was the problem, but it stayed even after flashing Juggernaut.

so what did u end up doing, fool around w/the power button or did u bring it in

[Q] No tablet display but HDMI works.

Hi,
Yesterday (08/02/2013) I updated my tf700t, everything seemed to be fine after it rebooted, I was playing a game, the battery was low, and it turned off abruptly. I assumed it automatically shutdown because of the battery, so I put it in the dock and plugged in the charger. Several hours later I tried turning it on and nothing. I held down the power button for 8 seconds felt the double vibration, but no display. I tried various combinations of docked/undocked, power cord plugged in, holding the power button for 30-60 sec. etc. but nothing.
Out of curiosity I connected the HDMI to my computer monitor and sure enough, it was there, I could unlock it and everything seems to be functioning fine, just no display. The digitizer seems to work fine, although guessing where things are at is pretty tough.
I think I tried the cold boot, volume up/down (I tried both) plus power, and it didn't make a difference.
In order to do the update I had to flush the DMC Client and CMClient data and cache, I had been getting errors from DMC Client crashing.
Also I'm not certain this is update related, as the tablet had been acting wierd, which is why I did the update. I would press the power button to turn the screen on and nothing would happen, so I'd hold it down longer and the tablet would reboot and finally the screen would come on, or it would come on a few seconds after I pressed the button. I was getting a lot of reboots etc... I thought the update might resolve this.
I'm not sure if the problem is hardware, firmware, or software related.
I'm wondering if when I flushed the DMC and CM Client cache, maybe I deleted the drivers for the display or something?
My options seem to be:
1.) Factory reset by feeling around the digitizer while connected to HDMI
2.) Factory reset via the pinhole
3.) Install new (old) firmware via usb/computer. (the device is recognized by Windows 7 so I think this is doable.)
4.) Send it off to Asus. (would this be free?)
So my questions are:
1.) is there something else I should try?
2.) what order should I do the above in?
*Note: I'd like to save my data somehow.
*Edit: I forgot to mention I was on 4.2.1, no root or anything. Also I bought this in July of '12 so I'm pretty sure it is out of warranty. Any idea how much it might cost to send it off? Perhaps I could replace the LCD myself? I replaced the digitizer/screen on an ipod touch, although I'm sure this LCD is much more expensive and much harder to replace. This is turning into a nightmare. So much for trying to keep my data, now I hoping to keep this from becomming a paperweight.
Thanks.

A bloke at work had this issue. He let it rundown and left it for 3 days. It worked fine again after that.

If you don't even see the boot logo, it cannot be software related.

Thanks for the replies.
I'll try letting it run down. Would putting it in the freeser be helpful/safe?
I guess on the software/firmware it depends on the definition. To me drivers are software, firmware is anything written in VHDL. I suppose what I'm really wondering is if it is software/firmware vs. hardware, i.e. is the LCD or some other component dead or is the display just not getting written to, initialized or whatever.

I wouldn't put the tablet into the freezer.
Does the backlight come on? If not, it's definitely a hardware problem. If the bootloader boots fine but doesn't show anything, that also looks like a hardware problem.

I'm not sure about the backlight, I think maybe it does, it is kind of hard to tell. I'll try checking in a dark room tonight. Since the screen is just black I suppose I'm looking for a brighter shade of blackness?
The bootloader is definitely booting fine. That is what I meant in my original post, the HDMI out works, I can see everything there, I can even swipe and tap the digitizer and do stuff, it is just difficult to guess where things are at. Do I need to go back and clarify this in my original post?
Do you think this definitely means it is a hardware problem? I figure I'll try letting the battery run all the way down and let it sit a few days and recharge it as sbdags suggested, in the meantime perhaps I should contact Asus, but I'm not lookinf forward to that.

I don't know what is the cause but like I said I saw this with my very own eyes - the same as yours. Double buzz on boot not screen but HDMI worked. Somehow completely draining the battery fixed it ...... So hardware / software? Who knows? If it was hardware why did draining the battery fix it? The device has been absolutely perfect for 3 months since and has never done it again.....

Thanks sbdags, I will definitely try this. I'm not sure if I should hurry and contact Asus though, I bought this thing around July 22 2012 I think so it is barely more than a year old, not sure if they would cut me some slack on the warranty or not.
Do you think I need to let it sit three days or just make sure the battery is good and run down before charging again? Also I've seen some suggestions for charging from a computer vs. wall as it charges slower, do you think that would be better?
I'm getting into panic mode and want to make sure I don't do anything rash that limits my options.

All he did was leave it for 3 days. Our assumption was that the battery had completely drained in that time....... A charge later (he was actually just about to box it to send to Asus) and it surprisingly started as if nothing had happened.

Having the same problem
I am having almost the same problem, except that the tablet screen works when the wall charger is plugged in. THe HDMI display and the digitizer work fine. It is just the tablet's screen dispaly when the charger is unplugged.

So I didn't have any luck letting it run all the way down.
I contacted customer support, the warranty is only 1 year, but fortunately for this there is an extra 3 months, so I just managed to squeak by, although I'm keeping my fingers crossed.

same problem as you both
i have d same problem well until last week the screen displays when conne ted to wall charger now its all blank but iy works via hdmi, digitizer works fine but all blank, this tf201, does anyone know if i change d whole display it will work?
i already bought the tf701
any suggestions is welcomed and did you get youra to work?

I have not seen people mentioning VHDL and verilog for a while, hahaha... It sounds like you are a low level or physical layer programmer. Any way, a firmware is in general a low level program that communicating with the hardware and the software or high level program ( level 7).. If you will, a firmware is a management levels (level 2 and 3). A VHDL is a level 1 which generates a 0's and 1's or mapping the transistors in the FPGA chip for example.... Oh well, it is just my definition...

I suppose what I'm really wondering is if it is software/firmware vs. hardware, i.e. is the LCD or some other component dead or is the display just not getting written to, initialized or whatever.

If you can get the output from the HDMI port, it is more likely you have a hardware problems. I think that the problems are your display related hardware. If you really want to troubleshoot your issues, you can look on the mother board to locate all the electrolytic caps and check to see any abnormal signs of those capacitors. Those caps are the one that will blew up first before any others parts go....Good luck...:fingers-crossed:

N5 in bootloop - possible hardware fault related to power circuit

Hi guys
Unfortunatly my time has come to have a possible hardware issue.
Yesterday my N5 was connected via USB (like I usually leave it resting at work / charging) and out of the blue, rebooted. Google logo shows up, and reboots right away. Trying VolDown + Power shows up the menu but I hardly have any time to select bootloader or recovery, and when I do, it eventually reboots again after a couple seconds.
I'm able to turn it on and have it on if I avoid touching the power button, when I do, sometimes it works (screens just turns off), sometimes ir shuts down after a few seconds after doing so. It's not always, but happens three out of five times.
Connecting the USB cable has the same behaviour, sometimes it's alright and I'm able to copy files and so on, sometimes it shuts off and there it goes into bootloop again.
So, I got home, opened it and I looked like a donkey looking at a castle lol. I had a disconnected brown wire on the right side of the battery which I was able to fix, but that doesn't seem to be the cause of the problem.
The power button feels ok, it's not exactly rattled or anything, it has on/off feeling. if you know what I mean.
Problem is, I bought this in second hand in london about 6 months ago, would be hard to RMA and probably they would give me the finger.
Anyway, suggestions? Anyone went through anything like this? I doubt it's a software issue (rom) cause the same behaviour happens when on recovery / bootloader. Sometimes it holds on and lets me do things, sometimes it doesn't. Most often, doesn't.
Any help or tips are greatly appreciated.
Thanks guys.

I can't, was bought in second hand in a shop, besides I opened it and the water sensor is pinkish (never touched water, probably humidity).
I can only do that around christmas time.
Any other tip ? Something I can do before considering something like that?

By sending in for repair or replacement, I meant to LG. Not Google for RMA.
LG will charge you for the repair or replacement.
There really isn't much you can do otherwise.

Pixel 3a always on and bootlooping, any suggestions?

Hello.
For maybe the 5th time I just took apart my old 3a that my son's been using. I was going to replace the battery, but turned out the battery I'd ordered (OEM and fresh from the wrapper) was bad (puffing up). Needless to say, I didn't replace the battery just now. The old one was managing ok, so definitely wasn't dead. I removed it carefully, so figured I could just reinstall it until I got a better one.
Having put the phone all back together (unfortunately, breaking the cable for the fingerprint sensor along the way, but AFAIK, that would have nothing to do with my problem), I found the phone was bootlooping. Not just that, but once I took it back apart, I found that as soon as I plugged in the battery to the motherboard, it started to boot. Holding any combination of buttons didn't stop the bootlooping. I'm just seeing the start screen (it's rooted) and maybe a flash of the Google logo, then back again. I can't turn it off without unplugging the battery.
So now I don't know what to do with the thing. I thought I'd just put it back together and let it limp along for a while, but suddenly it's hosed. Has anyone else experienced this kind of behavior and found any fix?
Thanks

Never took my Pixel 3a apart, but first thing I'd check would be power button - it might be stuck (always pressed), might be "shorted".

I didn't want to complicate the story, but I did also replace the entire power switch. No matter, it does the same thing with the old power switch, the new power switch, everything connected to the motherboard, or nothing connected at all except the battery. Also, whether or not it's plugged in. IIRC, the battery had over 60% charge when I started this morning, and it's been keeping the phone going for a whole day. I feel like something must be up with the motherboard itself, but don't really know.

Could the touch sensor being broken actually cause this problem? That's the only thing that's different. I don't even know how that cable got broken, as I tried to carefully remove it from the motherboard. But it's done, and to test that theory, I'd have to buy another.

how is power switch connected to the motherboard? Is that connection 100% intact nor damaged? By the way, if fingerprint cable is broken, maybe that connector is damaged too and is causing short circuit?
And can you enter fastboot or recovery mode?

Sorry, this might have gotten buried in my last reply:

I don't have the broken fingerprint sensor cable attached at all. Tried it once, but figured that was pointless if not counter-productive.
I've also cleaned all the accessory contacts, including the one for the power switch, using 91% isopropyl. The only thing I haven't done, and the last thing I can think to try, is to really hit the motherboard with compressed air, especially the contact for the power/volume switches. I just know it worked fine after taking it apart multiple times, before this last time.
If it's not some damage to or debris in the power-switch connector, at this point I'm thinking the motherboard's gone bad in some other way.

Asked over in iFixIt, and was informed that it may well be that not having the fingerprint sensor attached could cause POST to fail, so I'm going to try a new one and see if that helps.

New fingerprint sensor, per this recommendation. Phone still endlessly bootloops. Seems to be permanently powered on, cannot stay in bootloader/fastboot mode for more than about 2 seconds. The buttons all register -- e.g., if I hold down all 3, the phone goes black, but only until I release them. There seems to be no way to intervene in the problem. I think I may have to give up on this, unless anyone has further suggestions (beyond a new motherboard, since I've already invested too much time and money in it).
