[Q] BOOTLOOP please help :(

Hello everyone, I am looking for some help !!!
I have been using embryo for quite some time and no issues.... I have a i727R and just out of the blue today I was using it and it auto rebooted on me.... now it is in a bootloop... just boots to the samsung logo and then reboots (viberating over and over) with no screen indication
I can not get into CWM recovery either.... I have never had this happen to me ever and I am worried... I am on the road right now and XDA is my only source for help... can ANYONE please give me any suggestion how maybe I can get this phone working? I have a bad gut feeling I am going to have to go buy a new one for retail
anything at all would be great
Thank you
I did not change anything on embryo , it has been working for months 5.0 .5.1 and 5.2 just running stock embryo, no modifications to kernals or anything no overclocking nothing, just as is
PLEASE help I would love your for it and willing to donate if required
I can not access download mode either... i get the prompt to access download mode and the phone just reboots on me again
i popped out the batt for a good 20min ... i turn it on.... i get the I727R splash screen, then the samsung logo... then it vibes and reboots and keeps vibeing over and over .....
I put batt in it boots I hold volume down..... i get the screen for download mode, and once the full screen displays it just reboots and vibes over and over .... i think it might be bricked or pouched... but i didnt do anything to it which is what is bothering me.... im just looking for ways now to odin it to restore stock ... but i dunno how to fix this
I plug it into usb as well and it just vibes and vibes over and over again

Sounds like a stuck power button. Take a needle and carefully work around the edges of the power button to dislodge whatever debris is holding it down. There are also a couple of guides on here you can search for that'll show you other ways of handling it.

its a stuck power button, keep mashing it until it unsticks, its internally stuck, not noticeable from exterior

Did you keep mashing it down like vincom said to do? Trust me, this is a well-known and very common problem with Skyrockets.

yes it is not the power button..... cant be .... i mashed and used a needle and everything.... i go to download mode and hit vol up to enter it and she just reboots on me

if i plug the phone in with or without the battery it just vibes over and over again, doesnt even boot up once ..... but when i boot it with battery this is what happens
1 - put battery in phone
2 - first samsung splash screen (i727R)
3 - second samsung screen (2-3 seconds)
4 - reboot
5 - vibes over and over (no screen indication) continuous vibe
I am dead in the water on this problem (I was just using the phone like normal answering an sms and while typing it just rebooted on me and this issue above happened.
1 - put battery in phone
2 - hold volume down
3 - download mode spash screen
4 - auto reboots (vibe over and over) (no screen)

That alone has me convinced it's a stuck power button. Defenders are great for keeping your phone from being smashed, but they trap all kinds of dirt and dust underneath them. Almost positive your problems are being caused by a speck of something or other that got forced way down into your phone's housing and is holding your power button down internally.

I managed to open the phone and there is no issue with the power button being stuck .... It is now looking more like a software issue.... I can not access download mode or cwm perhaps with some of the issues i was having with the rom just made the phone go stupid and get caught in a boot loop not to doubt the rom ... just saying everything was fine for months and the phone just decided to auto restart on me and this happened

[Q] s3 i747 Water damage repaired partial problem left

Ok so my friend jumped in the pool with his s3 while on vacation.. lol Anyway like every other person on the planet tried to keep the phone on or turn it on before drying it out. Said he herd some sizzling light came on once and nothing. I took the entire phone apart cleaned up the logic board well with 99% alcohol and I can get the phone to fire up now but it hangs on the Galaxy S III screen. I did notice the computer installed drivers for it when it was plugged in.
Any ideas?
I tried holding the power up volume and home button at the same time It Just seems to reboot and do the same thing get a little flash of green in the top left corner something about a reset or something.
I tried holding the volume down and power button to connect it to odin but it does not connect and I do not get this yellow trangle I read about it just seems to boot into the same thing again.

[Q] Telstra One XL wont turn on after screen replacement

Hi Everyone,
I'm have a problem with my One XL. It's an Australian Telstra item. I got soaked in the rain and the phone got wet. I put it in rice for a few days to soak up the moisture, then charged it up. After this the screen backlight would intermittently fail, and i noticed if I squeezed the LHS of the phone it would sometimes make the screen go on or off. The problem got worse over the space of about an hour and eventually the screen would not come on. I opened up the case, and noticed there was a split in the ribbon cable that is part of the screen at the point that it is folded over 90deg (I'm not sure why this was never a problem before the phone got wet?)
So I stupidly got straight stuck into taking it apart to replace the screen before backing up all my stuff. I ordered a new screen of ebay and replaced the old one. Now I am having the following behaviour:
1-Press and hold power button - Phone vibrates once, then does nothing. Screen doesn't come on.
2-Plug into PC - LED flashes red for a while then goes solid red. Screen doesn't come on. Nothing pops up in "My computer"
3-Press and hold (~10sec) power after 2 - Red light goes off. Phone vibrates once every ~30 seconds. Screen doesn't come on.
4-Press and hold power after 3 - Home/Back/Apps LEDs flash 20 times, no other change.
I also tried a number of combos of power + vol -/+ with no success.
Also, I was being lazy and doing this without putting the case back on, and my power button has fallen apart. It looks like that ribbon cable is only ~$5 on ebay, so no big deal, but means I cant really do anymore troubleshooting at the moment.
So I guess the big question is, can the phone still be salvaged? I'm thinking maybe it's stuck in a boot loop with the screen also not working?
Any help is greatly appreciated.
Cheers,
Chris

The first question I have would be did you make sure you got the right screen? There are three different types of screens that came on this phone and you need to make sure you match it correctly. You can identify the type of screen by the colour of the flex cable attached.
Secondly, you should never use the power + volume up button combination, I'm not sure where you saw that information but it puts the phone into Qualcomm download mode which you definitely don't want. The only button combination that should ever be used is power + volume down.

Hi Timmaaa,
Both screens had the same orange/brown flex cables. I did read that there were different screens, but had thought there were only two and that the other had a green flex, so I definitely didn't get that one. Are the other 2 colours close?
I'm not sure where I read the power + volume up thing as I have read a heap of different threads. What would the expected behaviour be if I had put it into that mode?
Thanks for your help.
Cheers,
Chris

The three different screens have very different colour coding on the flex cable, so matching should be a piece of cake, which I believe you've done correctly. Putting the phone into Qualcomm download mode is kinda like a bricked state, if you're getting the red charging led and the cap button lights flashing I think you're ok.
Another thing to note is that you usually need to sync your new screen when you install it. From memory I believe you need to power the phone on, remove the old screen while the phone is on, and install the new screen while the phone is on. If you didn't follow this process that might be why your display isn't working. Other than that your phone might have just suffered some fatal hardware damage due to the liquid ingress, which isn't going to be fixable.

Thanks again Timmaaa,
I had a closer look at my old screen and it does have the small green section on the flex cable which I didn't notice the first time around. Bugger.
So i disassembled it again and swapped back to the old screen. The display still doesn't turn on, but the phone itself now stays on and the computer recognises it! I'm transferring all my photos across to my computer now, then I'll try to sync it properly and see if that helps.
Cheers,
Chris

Ok so I swapped the screens back and forth with the power on, and now it's working! Thanks Timmaaa, I would never have guessed I needed to have the phone turned on in order to swap parts, seems pretty weird. Now just got to get a new power button.
Cheers,
Chris

Awesome. Glad to be able to help.

[Q] HTC 8x stuck and rebooting after logo screen

Hello,
Had a perfectly fine HTC 8x till this morning. Then the pet at home chewed on the USB cable while the phone was charging .. I suspect the power cables may have shorted with the data cables. In any case, now the phone is totally dead when the charger is disconnected. If I reconnect the charger (new cable) then the phone vibrates, afer that the screen lights up for about 10 seconds with the HTC logo and then it switches off - it keeps doing this till the time I remove the charging cable. The Red charging LED does not come on at any time. I have tried the hard reset with Vol down and power key etc. and that did not work. Any help to revive the phone would be greatly appreciated.
Thanks & regards

I bought one listed for parts on ebay a while back that would do a constant boot loop. what i did was buy a cheap phone tool kit 2$ off ebay as well. removed the rear shell on the phone. dang phone is held with sticky adhesive. its take a minute to separate the housing and screen. if you have watched those videos on youtube where there using a blow drier to heat the plastic to take the phone apart is completely nuts. It only takes patients and dont force it . then disconnected the battery. 2 whole screws. woo hoo.. i couldn't do the hard reset either because the phone woudnt charge in off-mode. just constant boot loop. i had no choice to battery pull. strange thing was the charging light would always stay on even when it was unplugged. once the battery had been disconnected from the pcb it hasn't had any problems.
T-MOBUS HTC 8x Developer Unlocked, Sim Unlocked, and Running Windows 8.1

[SOLVED] Disconnect the battery from the phone for few seconds
Problems faced:
1. Boot Loop
2. Factory Reset using Phone buttons never worked, tried everything and never ever got the " ! " icon
3. Phone keeps restarting showing the HTC logo without "quietly brilliant" ( if you don't see that probably not going to boot the OS)
4. Phone does not work at all unless connected to phone charger
SOLUTION:
After trying almost every possible thing i got this to make it work.
1. Open the back cover ( you will need a hair dryer, check YouTube)
2. Unscrew just the two screws at the bottom of your phone and disconnect the clip-pin thingy (this connects the battery to the phone) for a few seconds. ( it has a metallic cover kinda thing)
Press the power button and your phone will go back to normal.
Make sure you connect anything that gets disconnected in the process... they are quite strong so dont worry, nothing will break or cut off, but do be careful.

hi there ok i found a solution you need to take the cover off and the plug in the charger because a button is stuck
there is only 2 screws you need to unscrew and boob it works

My Case

MY CASE... I've posted a thread explaining that...
This procedure works.. but in my case not at 100% fine... cause i can't insert back the sim card since the bootloops return if i do it...
That left us with a software issue i've not been able to solve yet...
Best regards...

(Help)Hard bricked U11

Never thought I would run into this moment that I need to ask for help on the forum, but I guess this is my last hope.
Here's the story:
I was on Oreo firmware and thinking of going back to Nougat because there are some apps only work on Nougat at this moment and I overall prefer Nougat design.
My phone was on S-off so I thought it would be perfectly fine for me to just flash Nougat firmware then flash the Nougat rom I desired like the good old days.
So then I launched Sunshine app, passed the compatibility test and the phone rebooted to download mode with S-off shown, everything was working fine so far.
And here was the problem happened, I typed in the command"fastboot flash zip firmwareXXX.zip".
Terminal showed error needs to reboot and flash again immediately as normal, the phone rebooted but never come back to download mode.
Now it only stays on black screen, if I tilt the phone a bit I can see the backlight glowing.
I've tried hard reset by holding power and volume down, it will reboot but still stays on black screen, neither system nor bootloader is accessible.
Even plugging to the computer detects nothing, not even QHSUSB_BULK mode.
However, the phone is able to charge though, I hook up the usb cable with a digital meter and it shows 5 volts and 0.5 amp.
I'm running out of solutions, I've searched through the entire forum and see no one has the similar experience.
This is the first time I hard brick a phone, been a loyal HTC user since good old Desire HD days.
If anyone has experience or solution for this, a kindly help is appreciated, thanks!

Have you held the power and volume down button both together for exactly 1 minute,
I have a u11 that took for ever to reboot with corrupt os youll notice the capacative buttons start flash if its doing something or going to reset after about 30 seconds if not and nothin happens
Take the backing off and unplug the battery,
To do this heat the backing up with a hair dryer and get some really fine guitar picks, work your way arround slowly, in my case the U11 was not glass backed only plastic and was original backing ive heard they are glass now though so be careful,
Now with the backing off and exposed, take all of the 5 or 6 screws out from the plastic ariel cover with NFC chip attached (chip is gold bend it up off battery it is not glued down)
Then from the left of the device at the bottom of the plastic cover with ncf chip on it you should see a slight gap where the vibration motor is located and sits
Get a rounded pair of tweezer and insert just the tip into the opening and very carefully pry it up, it make take a while as some of the adhesive from the backing will be holding it down,
After that is off you have now exposed the devices PCB,
From the battery youll see the connector making its way to the PCB port disconnect it and reconnect it now try to boot directly to download mode with
Power
Volume down
Both at the same time, if this did not work the disconnect the battery again and wait 24hrs for the static electricity to disperse and try again, had this work on a completely frozen unresponisve evo 10 and u11 + and also my U11
Still no luck id say the emmc on the board has gone haywire either that or possibly one of the thermal transistors has blown in which youll see either black and burnt or white and powdery,
Im a phone tech you shouldnt have any problems doing all this just take your time,
Good luck mate

I've tried holding volume down and power buttons both for around 5 mins, no capacitive button blinking.
However I can tell the phone reboots several times during the procedure by seeing the backlight goes black and light up.
And about the reconnect battery route, I guess I'll just do it anyway, since the repairing price might be the same as buying a new one.
Thanks for the reply, mate!

Sounds like the logic board is trying to initialize but there isnt sufficient power to boot it,
its kinda like when you take the battery out of a phone then plug it on to charge without a battery and there is nothing but a lit up black screen and nothing else happens as theres not enough power to boot, this sounds the same to me as there are no red or green light after the orange when plugged in,
Get a hair dryer and heat the back of the phone up a few times and then plug it into charge to see if you cant boost the cells back to life, do this a few times,
If no change id most certainly suggest removing your back cover and unplugging and replugging the battery, once unplugged leave it for a few minutes, then plug back this will refresh the chips (especially emmc as this contains your entire system and bootloader, including download mode, RUU mode)
as soon as battery is reconnected plug it in on charge and try to boot it to download mode straight away also look for any change in the batteries light colour and any blinking,
the orange light when first plugged in is normal but should blink once or twice only then change to a solid red for discharged and charging or solid green green when near on 100% charged
If the above does not work disconnect the battery for 24 hours and try again, this will fully drain any static electricity in the device that may be lingering,
If still nothing after the 24 hours buy an OEM battery from ebay and install yourself, once you have the back cover off youll see the battery takes up 3/4 of the phones actual internal size,
Same as the back cover get your hair dryer place a shamwow or thick cloth over the PCB board then heat the battery up (NOT TO MUCH THOUGH only so its hot to the touch), then with the really thin guitar picks again (they should be bendable easily and flexible) work your way around the battery to cut through the adhesive securing it down,
CAUTION be very very careful the adhesive is strong keep the battery heated at all times to avoid pericing the battery and or damaaging the lcd as this is what its secured to, just take your time and work slowly do not force it out, once all the adhesive is cut it will remove easily by using the guitar pick insert between battery and housing and gently turn the pick from left to right and will pop out, (you will see the battery move when using pick from left to right if not you havent cut the adhesive properly work around the battery once again until you get movement from it)
Sorry for the long reply haha but dont send it to htc they are absolute rubbish hope this helps ive tried to be as detailed as i can its actually alot harder trying to explain it than it actually is to do it

what should i do now, please help me, and sorry for my bad english. Thanks a lots
