[Q] HTC One X not switching on

Okay, first of all, I would like to mention that I'm new at all of this.
I brought this phone 2 years ago and 2 months ago I decided I was going to root it. So I switched to CyanogenMod 11 M4 and did everything that was required i.e., unlocking bootloader and flashing a recovery and all that.
Just 2 days ago my phone showed an update available to CyanogenMod 11 M5. So I downloaded it and then the phone took me to my recovery. There I made a backup and flashed the M5.zip file that was downloaded. But when I rebooted my system a popup came saying com.process.phone has stopped unexpectedly. I pressed OK but it was persistent. I had no idea what to do so I booted into recovery and wiped data and then performed a restore of my previous backup that I had taken. Half-way through the backup the phone just switched off and then restarted with the traditional HTC logo and then it switched off again and restarted again and this process kept looping.
I loaded my bootloader and connected the phone via fastboot to my computer and erased the cache and flashed the recovery again. Then wehn I restored it started working normally as it did before.
But the battery was around 20% at that time so I left it to charge overnight. When I woke up the next day it was insanely hot and the LED was constantly red but it wouldnt wake up. So I loaded into recovery to restore it again but it kept on saying "Error mounting /system!"
And then after a few tries it switched off. Now it won't wake up again. Even the LED seems dead.
Has anyone of you ever encountered a similar issue? Any help would be appreciated. I've tried all the button combinations that are recognized by the device but nothing seems to work.

dead battery
i guess its because of corrupt or dead battery
try giving external power or replace battery and try
further you could even try other options like booting cwm
flashing last kernel image found

Booting CWM or flashing the last kernel image aren't an option because the device doesn't switch on at all. I cannot access the bootloader.

try changing battery
try changing battery by buying new battery and connecting
or remove battery and charge it with external source i guess u must have heard of jump starting battery

After the phone updated did u extract and flash boot.img from M5.zip?

No, I didn't do that because when I switched over from a CM11 Nightly to CM11 Snapshot M4 I didn't extract and flash the boot image even then and everything was working perfectly. So, I didn't think I would need to.

U should give it a try, since some CM updates triggers the kernel itself so boot.img should be flashed again.

That is the problem. I can't. When I connect it to the PC it just never shoes up and I have no luck getting into the bootloader. Do you know of any reliable unbricking guides? I'm guessing my phone is possibly bricked.

Nah, nothing is suitable. There are guides on how not to brick your device but nothing to unbrick it. :|
Thanks anyways. It's appreciated.

Another bricked HOX apparently. There seem to be loads of these on the internet. In my case, it can't have to do with custom roms or rooting since I never messed around with stuff like that. I even opened the HOX and checked all cables etc. There is no part that looks damaged or otherwise suspicious.
What can we do? How can we at least get access to the data in the internal memory?

Don't know if this will help, but it might be that it hasn't actually charged properly over night and has drained itself to death.
Try plugging into PC and get to fast boot.
Fastboot = Volume Down + Power Button
Then make a batch file out of this:
" @echo off
:start
fastboot getvar battery-voltage
fastboot reboot-bootloader
ping /n 6 localhost >nul
goto start
"

Unfortunately, there's no way this could help. because the HOX is literally dead. There is not even a charging indication when plugged into a PC or the wall charger. And thus it's not recognised by the PC and fastboot won't find it.

[Q] Nexus 7 suddenly bricked ?

Hello all, so yesterday I went on my tablet (Nexus 7 2013 WIFI ver.) and browsed the net a bit and went to sleep. I recall having around 30% battery power. This morning I wake up to an apparently flat battery (power button didn't turn on anything) so I just plugged it in and did something else. After a while, I took my tablet and started it with the power button. However, it got stuck on the Google logo and never fired up anything. I've rooted the tablet quite some time ago (months) so the cause is not from there.
Things I haven't recently done:
Installing an app.
Rooting or flashing anything.
Updating an app.
Things I have tried doing to fix the problem:
Booting into FASTBOOT then trying the recovery mode = still stuck on the Google logo.
Booting a custom recovery image using Wug's toolkit = frozen at the team logo (TWRP) / black screen (CWM).
Flash Stock + Unroot (Soft-Bricked/Bootloop) = FAILED (flash write failure).
So now I'm really stuck and desperate to make the device work again. I've been reading all day long and trying all sorts of solutions to no avail. And it seems far-fetched to me for a device like this to just instantly brick itself without any reason at all.
Can anyone help me with this case ? Or does anyone has any idea what just happened to my tablet ? :crying:
EDIT: I'm afraid that warranty might not work as the device was unlocked and rooted so it's the last solution for me.

Bumpity bump
No one has any idea what happened to the tablet and how to fix it ? I've tried doing some more flashing but to no avail. It just refuses to flash and keeps failing to write the files.

I think you need to leave out on the charger for 1/2hr without doing anything with it. You are probably using what little power it has charged by trying to reboot it, etc.
I had to do that once and it did the trick.

There is no reason you should not be able to get in to recovery (power and volume down).
You could call Motorola. They have good tech support.

The exact same thing happened to me. I rooted it months ago and haven't changed a thing since then. It just froze up a few days ago. I restarted and it just gets stuck on the google screen. I can get into the bootloader, but when I try to go to recovery, the google screen comes up and won't go away. I've tried every method I can find for flashing the stock image and absolutely nothing is working. I just get stuck on the google screen.
Please update this if you find a solution!

Do u guys have the most up to date version of whatever particular recovery that you're on?

Yep. I've flashed the stock recovery multiple times to no avail. :/

If you can't get into recovery or flash any images it sounds to me like a hardware failure. Bad memory maybe? If you've tried everything then RMA to Asus before the one year warranty runs out.
Have you tried to see if your computer sees your N7 by typing fastboot devices if you have the sdk installed?

Yes, I can get into the bootloader just fine and I can use fastboot. I go through the flashing process and the command prompt says everything flashed successfully, but when I restart the device, it hangs on the google logo. The same thing happens when I try to boot into recovery.

If you fastboot flashed the factory image and can't boot up then it sounds like a hardware problem. Out of ideas, sorry.

I'm not sure what happened, but I just ran this little utility again (I've done it many times over the last week or so to no avail) and it actually worked. Hopefully it keeps working!

Device semi hard bricked?

Hello,
i have a huge problem with my s4 mini. The device wasn´t rooted, neither it has a custom recovery. It´s simple stock. But a few days ago, it turns off by itself and didn´t boot anymore. It stuck at the first Samsung logo, then it vibrate and reboots. I also don´t come in recovery anymore. Same here, it vibrate after 5 seconds an then reboots.
I read across the internet and found, that maybe the power button is damaged, but knocking on it etc. doesn´t help. I also successful flashed a new stock image with odin, but it didn´t help (so downloadmode is working fine). Any ideas what i can do? Maybe it´s the battery - the device is more than 2 years old, but battery isn´t blown up.
Edit: Charging isn´t possbile, same problem as recovery - battery icon appears, then reboot.
Thanks in advance

Is it the same as these guys?

Not really. I can put the phone in download mode with no problem, my PC recognize the phone as a "Sasmugn Galaxy S4 Mini ......". As i mentioned, flashing via odin also workes, but doesn´t solve the problem.
Thanks anyway.

Yes, maybe it is battery or hardware (assuming the software you flashed is good, md5 checked OK) Hope you find a solution

I will get a old S4 mini from a friend, it´s also dead, but maybe i can use the motherboard or the batterie, if not i will buy a new batterie and report the results here.
Reading across the internet, dead S4´s are a common problem.

For anybdoy else with similar problems: I bought a new battery, so the phone starts booting and i can enter recovery, but now i get bootloop and in recovery there are some error messages like e: can´t mount/data.../cache etc. So i think the internal storage is damaged.

Think ive killed it :/ Tab S2 T813

ok so bottom line is, I was in the middle of flashing official rom when at about 25% it failed. Don't ask why! (i still had recovery at this point) so I went ahead and cleaned absolutely everything thinking i'll just try and reflash as before. Now with power lead out it won't switch on at all and when power is supplied it shows message "An error has occured while udating the device software." loops at approx 3 sec intervals cant do anything with it.
Ive tried everything I can think of all to no avail! yes its my own fault bla bla bla just wondering if i act have f***** it.
Thanks to anyone with any ideas

You probably going to get a better help at TAB S2 board this is for the tab S1.
If it is hard bricked there is JTAG methods that can help, just need to find one for your device, not easy though.
But all I can do is share my experience with something like this, in a more "cheap" way than JTAGs, dunno if it helps:
I never had a similar problem on the tab S. But in the past a galaxy player 5.0 of mine had a very similar problem (as far I remember the screen just powered the back light but without any letters or simbols)
in 2012, I bricked it trying to mount a swap partition (280mb RAM ftw) accidentally pointing the wrong partition, and got the entire internal storage corrupted.. everything.. system, bootloader, recovery etc
My player was turning on only connected to a USB or charger, like yours. in fact It was hard bricked
I was able to recover it using Linux (because it is the only system able to communicate with the bricked device I had)
The problem is that everything need to be very specific, for example I used a software made for the galaxy s1 to "revive" my player 5 (both have the same hardware) it just made the device be detected via ADB. So I needed to prepare a SD with the same size as the internal storage (in this case 8gb) using the Linux terminal to mount in the SD an exactly schematic of the internal memory using a dump of another device that a xda user shared, (the dump was empty only with the bootloader, recovery etc) but it still had 8gb decompressed. So after that I used ADB to push the SD card content to the internal memory. And it get back to life \○/
Well.. it took me 1 week with a guide!! On the trial and error method. But it worked.. not perfectly, I get bootloops every time I try to flash a rom via Odin, but recovery works, and I have the device working until today

Hi, I Greatly appreciate your reply and advice. Think tho that your solution is a bit beyond my know how I know a little about ADB etc but i would have difficulties in compiling necessary files to sideload. Also many tanks for the link din't realise. Thanks Pal!

If you can get it in to download mode you can flash stock rom back on it.......refer to xda samsung tab s2 for more details on this........

thx for reply but it reboots approx every 3 seconds so I dont have enough time to do anything with it :/

Plug in changer and push power and volume up and down all together and you will see the battery charger icon then you can get it in to download mode from there.....

Stinka ure a superstar (atm!) I did as you suggest to no avail but I noticed a slight increase in the time it took to start rebooting again. I do not know which buttons did this but some 20 later it lasted long enough for me to be able to flash twrp. Now i havent actually tried that as yet as i wanted to check with you first... I have the battery logo on screen, i tried recovery and it started as it should but then rebooted, now im unsure at this time whether the battery is almost dead or not so i got it on charge and have the grey battery with a white flash inside... is this what i want for now until its charged? if so i'll keep you informed thamnks more than u know if uve helped me fix this, the reason i was flashing was because when i received it (no warranty!!) the screen sometimes flickered and it would constaly end up rebboting after digging around re that im lead to believe it need a new battery and for the connecting wires to be resoldered. Anyways thanks again n as I say i'll keep this updated
Cheers
Tony

one of the probs i hab/have with this unit is that it takes approx a day to fully charge!!! when i received it the screen flickered on the odd occasion but it was rebooting much more frequently. It came with stock n not messed with previously (i new this prior to purchase so got it for right price thinking it only needed flashing, how wrong was I!!!) so I flashed and encountered the above mentioned problems! thanks to stinka I surprisingly managed to flash a recovery... now provided all goes to plan, which rom would one suggest for stability and generally hassle free and prusuming the aforementioned probs, rebooting etc are still there what could i try to stop that? other than a debloated stock I found Lineage an excellent rom but still the problems got so bad the unit became unusable and was lucky not to go out the window. Im thinking do i start with a replacement battery and check the wires etc or could this still be a software issue??

if i endevoured to do the hardware myself would I attempt it by removing screen or the base for access to battery/connector??
Thanks again

In the tab s1 the best way is removing the back cover, but for some reason tab s2 seen to be the screen... at least in this guide: https://www.ifixit.com/Guide/Samsung+Galaxy+Tab+S2+Battery+Replacement/56616
Look like alot more complex than the s1 :/

My guess is your issue is lack of charge in the device. That's the reason for the flashing failure and the reboot loop with the firmware error.
Bang it on charge for a while then irrespective of what it's doing, whether it's looping or not, hold POWER + HOME + VOL DOWN until download mode appears.
Reflash the stock firmware with odin.

swapped battery and reflashed stock via odin. It has helped although the issues are all still there its just they happen less frequently which doesnt mean its any less frustrating.

Weird Bootlooping A50

Hello, I've tried my best but really am struggling.
When I first got the phone the only sign of life was when charging it there was a charging circle. I managed to play around and now while plugged in I am able to get into download mode while holding Volume Up + volume Down. However, the phone is continuously looping while plugged in (unless in download mode) & does absolutely nothing when not plugged in. When I get into recovery mode it instantly reboots, and whenever I try flash stock firmware I get PIT or bootloader error (<ID:0/004> Complete(Write) operation failed.). My suspicion is the fact I do not have the correct stock firmware but for whatever reason I cannot find the firmware for this model (SM-A505FZWDINS, Indian version).
Does anyone know what I should do? I'd like to give life to this phone but I'm really out of ideas.
Thanks in advance,
icecub

How definitive is this?

Is the battery know to be good?
If you don't know assume it's bad... everything you're stating indicates insufficient battery capacity.

Try twrp rooting formate then re flash stock firmware make sure Odin is the correct version this also happens when I don't have correct or upto date version hope this helps

same **** here. for me i cant charge the battery too. but before that with about the same problems i got it to work again for a few days.
funny that i saw more ppl at the last time here with the same problem. but i flash a stock firmware. R11 but it dosent solve it for a few days.
now it hangs allways on boot or warning logo for unlocked bootloader. i have used this phone over a year without this issue.
