[Q] RAZR XT890 stuck in Motorola/Intel logo

Hello guys.
About an hour ago, I tried to access my WiFi configs, and realized it would take me back to the start screen. So I rebooted my phone. The thing is, it is now stuck in the big red Motorola/Intel logo, and keeps looping.
If I try to turn it off by using the Power button, it doesn't work. If I try to reset using Power + Vol Down, it just restarts the loop. I can't get into recovery mode, because it won't turn off.
I really don't know what to do. My phone is still trying to boot for the past hour, and I really need it, asap.
It is running Android 4.1.2. No root. As stock as it gets.
Any advice, guys? Please

I have the exact same problem.
My phone (non rooted, stock Android) has been freezing quite a lot for the past 1 or 2 weeks. Sometimes rebooting on its own, sometimes I had to force it. This afternoon it froze again and I had to force reboot, where it started freezing at the Motorola logo. I cant go any further since rebooting just makes it loop that way.
I waited for the battery to deplete so my phone eventually turned off, charged it back at around 60% and tried to go into recovery mode with power+volume up+volume down. Same results. I don't think I could have failed the recovery mode procedure because I had practiced and knew I would only get 1 chance of succeeding.
Anyone has experience with this ?
I will see if Motorola or my retailer will repair/replace it for free under warranty terms, otherwise I will try opening it up for some cleaning and maybe further attempts with control over the battery.

Well, Motorola did repair my phone for free, but I live in Brazil. It took them 1 day to repair. They say that part of the circuit board was damaged, but I don't know what could be the cause. Maybe overheat? I don't know about your phone, but mine would get up to 50ºC while using Skype.

Low battery bootloop but accessible via PC (fastboot & flashmode)

Hey community,
i bought a sony xperia z3 three months ago.
Yesterday I recognized that my phone was at 50% battery after charging the whole night.
I thought that its a bug or something and I got my real 100%, but after ~3 hours it was still at 50% and suddenly there was the "you have to charge your phone"-pop up for 1ms.
So i decided to plug in my charger and thought my phone will charge again. But no, the battery icon also switched from 14% to 50% in this 1ms. It was going on like (13%<->50%, 12%<->50% and so on) this until my phone died and got 0%.
I haven't unlocked my bootloader, flashed it or something like this. It was the original vodafone branded sony xperia z3.
Until now I can't charge my phone, because everytime I plug in the charger, my phone is booting with the low-battery icon and after 5 seconds it's turning of in a loop. Booting for 5 seconds and then shutting down and so on...
I thought my phone will have enough battery when I will plug in the charger for the whole night and my phone will try to start in this loop until it has enough battery. But again, nope!
Now I decided to unlock the bootloader and flash my phone with Cyanogenmod 12 or CMW, because my phone is accessible from the computer. I can go into the flashboot and flash mode.
But also after unlocking and flashing I've got the same thing again. It won't start.
I tried to charge it for about 4 hours in flashboot mode, because then the blue light is shining and my phone is not shutting down. But NOPE, same **** again.
I don't know what I can do anymore. Can you help me?
Do you think I have to change the battery?
Looking forward to hear from you! It's only three months old never dropped or something like this.
greetings and sorry for the wall of text
shimmy
bro warranty covers that, but as soon as u unlocked bootloader, u kinda voided that too =(
go to Vodafone and DO NOT mention that you unlocked bootloader and explain the problem within 2 weeks of purchase u should receive a brand new device and afterwards they'll repair it for you
I have a small crack (2mm thick and I think it came from pressure) at the backcover and asked vodafone if they can change my backcover, because now it's not guaranteed that it's waterproof.
They said no, because it's my own fault if something is cracked or broken on the case and I have to pay 259€ to get a new one.
Yesterday I called vodafone again because of this problem and they won't repair it, because of my first support case and I have to pay 259€ to get a new phone. I was arguing for about 1 hours that this is a guarantee case and it has nothing to do with the crack, but they don't care and there are some laws that I could say that they have damaged my phone and so on. No chance.. Maybe I should call my advocate.
I read something about locking the bootloader? Maybe I can flash a stock version and lock the bootloader?
Try yellow reset button.
I also tried this before. It doesn't fix the problem.
Hi guys, Sorry to bring up such a old post but having a similar issue.. My Mrs phone just started rebooting one day, Vodafone refused to replace because tiny crack. The boot loader is unlockable I tried repairing with xperia windows tools the flashed older and different firmware's many times. The phone works when connected to PC but when unplugged or on normal charger just constant reboot.
Any suggestions on what to do?
Thanks

[Fixed] Bootloops after failed battery replacement attempt

-mods, you may close/delete this thread.
[UPDATE]
Well this is rather frustrating....So I wasted an upgrade to the Turbo a few weeks ago when I thought i destroyed my Maxx some how. Just over 2 weeks after I replaced my phone i came home from work to just put my Maxx back together since its been laying on my desk torn apart. I put the screws back in and snap the case back on to it, flip it over, push and hold the power button and wouldn't you know it...the Fawking thing boots up even to the same exact battery percentage that it was at prior to it being taken apart, along with all the battery stats as well.
Now my question is what to do...Sell my Maxx and keep the Turbo, or sell the Turbo 64GB (get more money) and wait for the new 2015 phones?!?!
Anyone?? haha
[A few weeks ago I decided to swap a new battery in my maxx. I ordered one off of ebay, installed it, but wouldnt take a charge. I put my old battery back in and powered right up. I emailed the seller from ebay and he told me that the battery needed 10+hours of charging since it wasn't precharged. So i then installed my new battery and charged overnight...next day nothing. I then put my old battery back in and now it wont boot or charge. I did not damage any parts, break any connections, or anything of that sort (from what i can see). Now it wont turn on unless i plug it in and then the unlocked bootloader warning pops up and reboots, continuously. I can enter fastboot mode, but am not able to pull any files from my phone. I was wondering if anybody might be able to help me in my situation?? I watched the youtube videos and all, nothing is missing and i did every step to a t. Help!! This phone is in mint condition!!]

My quest for a new power button with a twist!

So my story begins with me purchasing a used white Nexus 5 for $155 from swappa over a week ago for my wife. *
Phone arrives in perfect condition.
I first unlocked and flash twrp via adb. I proceed with installing Chroma and elementalx. Spend few hours on making the new Nexus 5 the same as my wife's current Galaxy Nexus.
Phone is running great. Zero issues for about 3 days while the phone was just at home running. She throws the phone into her purse and goes to work. Within hour she calls that her phone won't stop rebooting…. *Oh no…. The dreaded power button issue… right?
So I'm assuming the seller did the old “whack against a solid object” temp fix and sold it. I have no proof of that so I'm assuming.
So what do to? Well fixing the power button is still cheaper than buying another Nexus 5 phone. Everyone one quoted me $60. It is what it is… at this point I could have gotten a refurbished phone but what can you do…
So you would think this is the end of my story, right? Wrong.
I go to a cell phone repair place close to my work. They have this tiny power button in stock and replaced it many times before. I come back later that day to pick it up and they have bad news… of course they do.
After the switch replacement, the phone did the same reboot. Goes to Google logo and reboot. If I fiddle with the power button I can get to the OS but reboot right away. The guy proceeds with that it is me rooting it that caused it and I need a new motherboard, price $100.
I started questioning if he really did replace the switch. If it was OS related, the phone would not have worked for couple days and then break randomly. It would not boot to the OS sometimes or at least it would let me boot into TWRP, right?
Long story short, I left with spending the $100 on getting this used $155 phone fixed. Super annoyed at this point.
So after this long story, is there any chance this was really OS related and not a faulty power switch or did I just got lied to and the power switch was never replaced?
For sure, you should've attempted to restore the phone through Google's factory images first. My power button went super wacky twice since I've had it(day 1 model). I just pulled it out, and now the problem is gone all on it's on.
When it kept rebooting, did you try booting into the bootloader at all?

I sure tried to get into recovery but wouldn't work. Just kept rebooting. I had a nandroid backup done a day before but the phone would not stay powered on for long enough to do anything. It was the equivalent of having no battery left and phone just shut down and attempted to reboot constantly. I took out the motherboard and played around with the button before I went out to repair it but it was the same results. If I "massaged" the button then maybe the phone would get past the Chroma logo and get into the OS, but as soon as I attempted to touch the power button again it would reboot.
I tried reviewing the old motherboard and unless this shop's soldering skills are top notch, I can't tell that the switch was replaced. The soldering point were identical to the volume buttons. When I questioned the store owner, he stated they are that good with their infrared soldering He took out a package of 3 Nexus 5 switches and one was missing... meaning he installed it.
I highly doubt it was OS related. If you brick a phone when flashing, then it would just be constantly in a boot loop, right? I know I can easily go into recovery and flash whatever .img I need to, but this was just nonstop reboot and different times

Struck in infinite Bootloop, Fastboot no help

my mi4i has been serving me for the last coming to 4th years, I do get once a blue moon auto restart or hang issues but all goes well after the reboot. Using Accubattery to monitor batt stats and it states health at 88%. Was using the camera to take some shorts when phone went into bootloop. Fastboot was ok so tried flashing stock rom, again goes into bootloop and duration of Mi logo appearing n disappearing narrow down to seconds. Read on forum some guys have success after changing the battery, how can it be?!? luckily for me have already bought a spare batt months back from china online stores. last try then to verify this “myth” to me. and indeed, once the new batt sits in, Mi logo disappears n android loads new rom! So end of story, if your beloved mi4i has reached its critical batt years n it decides to show you its logo over n over again, it’s likely A BATTERY FAILURE.
i am still looking for answer but not the batter.y.
After reading this, will look for one
Yeah, recently I had a similar issue, phone was rebooting randomly and than on the next day, even android was not loading and phone just rebooted although when connected to charger phone was booting successfully, problem was solved by replacing the battery(of an older mi4i)..one thing to complain is that Xiaomi stopped providing spare parts for Mi4i(even battery) so one has to replace it with local one which don't last forore than 8-10 months...Xiaomi wants it's user to change their phone every two years by not providing them with essential spare parts of old models .
