Why does my device enter in a boot loop? - Android Q&A, Help & Troubleshooting

I have an Alcatel One Touch Pop C7 7041x, I have rooted it, and it enters in a boot loop every time I try to replace a system file, such as a *.ttf font for example. Then the only way to fix the boot loop is to flashing a ROM. Why does not my device let me to replace any system file? If I am unable to replace system files then rooting my device is useless. What can I do? Maybe it is a hardware limitation by Alcatel? Should I buy another different device?

I had already done it. I tried to flash different ROMs that I found on the Internet but the same is happening. The phone keeps entering in a bootloop if I replace any system file. What's up with this device? It seems its root directory is unable to been writed even if I am a superuser.

I think there is a problem in some alcatel devices, as i can see there are so many people over forum complaining about bricking of their alcatel devices after changing font.

I think you are right, because this morning I took my mother's Sony Xperia U and did some tests. I rooted it, changed fonts, change system files... and nothing happened. The pone kept working seamlessly. Perhaps the issue of bricking by changing system files is only a problem of Alcatel phones. I will never buy an Alcatel... just in case!

[Q] app changed system files, stuck on bootup

Dear xda forums.
Unortunatedly, this is my first post and i will be asking for help rather than helping :/
So... my father came in a week ago with a chinese android phone that i cant tell what phone it is trying to replicate exactly.... thing is, no matter how much i look for this phone i cant find anything about it, i already searched a lot on how to fix this proble but to no avail...
I can give more details if you need them), but basically this is my problem:
I got a chinese phone that runs on 4.2.2, and after working a lot, i managed to install supersu via framaroot(superuser would not work properly).
Thing is, being the inpatient person i am, before backing up anything, or installing a recovery rom or any costum rom, i decided to check some apps that required root.
I downloaded the app anim mod *root* because i thought it was a good idea to change the animations of my phone
HERES THE PROBLEM i used this app and i could see how it was changing things in my system files, it then asked for a reboot, and now it wont get past the boot animation and it freeses right there, i can enter factory mode(which is in chinese and i did look up for a translation) and recovery mode:
In both modes i was able to reset the phone but the problem is still there, ive literally have been searching whole days now and i am quite frustrated.
My question: what should i do to fix this? i have root but no recovery rom , so is there a way i can install a costunm rom just to try?
If the case is that i changed a system file (animations) how can i change them through my pc? does a reset from the stock recovery reset the system files aswell?
I am new to this, but i am willing to learn and try everything that could fix this.
If anyone wants to help, you can ask me whatever you want, i can upload pictures if you want to help me identify it or the specs i managed to get from factory mode.
the phone says it is an alps model a76, but thi phone is nowhere to be found help me please

[Q] Alcatel 4030X Unbricking Method??

So yes I know I'm a noob, but I have SOME know-how on android, I have an Alcatel One Touch S'Pop that my friend gave me, he's tried fixing it but no success, fortunately i've found the software named "OT_4030X_20130507.tar.xz" he downloaded and told me to install onto it however I hae NO idea what to do with it or what program to install it with, the phone only has 2 animation, the first when its charging and the second is the boot screen, it also loads the android system recovery and has the option to install from sd card so if I can load the data somehow, how can I unbrick it this way or any other way?
Thanks

I think its just a caes of placing the file onto your SD card, going into sys rec, and choose "install from SD". Let me know how you get on as my 4030 wont boot either.....
Use the alcatel update software, is pretty mucho like re-flashing your phone

[Q] Allwinner clone. Soft bricked: black screen, reboot loop, recovery corrupted!

Hi I have an Allwinner A10 clone (Kurio 7), it is designed for kids but otherwise a standard android tablet.
After hours of googling I rooted and installed CWM & Gapps (not included in the stock ROM). So far so good.
The stock ROM was causing issues with some apps, it needed to go.
I flashed CM10 and it worked but no touch screen. It needed a compatibility flash to make it work. You can guess what's coming. I picked the wrong one and now the device does the following:
Reboot loop
Black screen (backlight though)
PWR+Vol up no longer gets to recovery
Vibrates constantly between reboots (due to wrong patch I'm guessing)
ADB picks up the device for a split second between reboots but "adb reboot recovery" does nothing. Even when using wait command.
Tried "fastboot flash recovery cwm.img" after wait command, no luck.
Is there anything else I can try?
I fixed this.
I used the GoClever TAB A73 ROM and instructions in their support/update/download area.
Sorry I cannot post links as I am still a newbie.
Anyway flashing using Livesuit this fixed the problem.

Hi, can you please share with me how you manage to unbrick your Kurio 7. I had just bricked mine trying to install CM10.
Thanks.

I guess this is the site he is refering to:
http://www.goclever.com/uk/support,c3/software-update,a28.html?aic=5&aia=185&ail=10
The LiveSuit pack is there for download, as well as the roms.
But there are three different 4.0 roms to choose from, and also a couple of 2.3 roms. I dont know which one he did use.
Since your Kurio 7 is bricked anyway, I guess you can try one by one and see if any of them work.
Please tell which one, if you succeed.

[Q] Star n800+ after rom flash shows only white screen

Hello guys, i need little help with my phone, so here is what happened: Two days ago i tried to turn on my phone, it started booting but the cycle repeated again and again so I got in recovery and wiped data/catche, but that didn`t helped. I thought that if i change the rom maybe I can fix the problem so I downloaded my rom from needrom (there were 2 roms for my device) and started flashing with Flash tool. I downloaded the first rom to my phone and tried to turn the phone on but nothing happened.. I downloaded the second rom and it worked, the phone booted but the only think that I can see is blank white screen, the touch is working and the buttons, when i click somewhere i feel the device vibrating but thats it. One time i managed to make the device appear in my computer as a normal android phone, dont know how this happened. So can someone help me please, if you have a phone like mine can you backup your rom and send it to me or help me find a working one, or some idea how to fix the blank screen. Thanks in advance

Phone won't boot after updating SuperSU

I need help immediately cause I am paniking. So I rooted my phone using the KingRoot application, and after the root was succesful used SuperSu-Me to remove KingRoot. SuperSu-Me installed SuperSU on my device which in turn had to install an update, so I let it do its thing. After the update was installed SuperSU prompted me to reboot my phone so i did. Problem is the phone has been stuck for about half an hour in the shifting shapes screen, fastboot doesn't work. I have tried hard reseting it but the problem persists.

My solution
I fixed it by unlocking the bootloader in fastboot mode, flashing TWRP and using it to flash the original version of the oxygen os, the one that came preloaded with the phone.

Help me pleaaase (( My phone is very important to me. I've been searching for forums and I only found yours that had the same problem with me. By now it's about 1hr just stuck in there ( please help me im begging you!

First, please don't follow instructions you're finding on this specific forum since it's for the OnePlus X, not the Starmobile. Secondly you needed to unlock your bootloader first, since you didn't from the sounds of it you can't boot into Android since it's now tampered. You'll need to boot into recovery, usually by pressing Power + Volume Down until it loads and factory reset your device.

Try to find out your solution in your device's forums, since this forums is for the OnePlus X and not the Starmobile Knight Luxe.
If your device is stuck on the bootup screen, you need to go to fastboot mode, unlock the bootloader (if you haven't), flash a custom recovery, boot into the recovery, and factory reset the device. It should work.
Guys!!! Thank you for all your suggestions. I did flash a custom recovery but it fails simultaneously. I just let it fix on a local phone repair shop just paid a few bucks
