Hi Guys,
So this is my first thread here and I'd like to ask something related with my devices, the bootloop
Details :
This morning I changed my system font, and it said to reboot, so I reboot from the pop up menu and here things goes wrong,it keep rebooting by itself, I tried to search and reinsert the battery, but it stay the same, after that I wipe dalvik-cache from CWM, reboot fix, and then reboot. The result is still the same, then I did factory data reset, and it still stay the same.
Now, I'm complete noob here, I've read this and can't understand 75% written on it, please give me a solution for this !
Another Details :
The font is Segoe UIL (Light) taken directly from my PC (Windows 8), is it what causing the problem ? I use the Font Changer FULL to change the font
Help ???
EDIT: SOLVED
Hi, I have a strange problem with my Xerpia Z2..
After flashing a cyanogen mod to test it out.. it`s not possible for me to get a working generic Android system anymore.
The smartphone stuck in a caint of "bootloop" or, if it start android at last, it reboots after a short while automaticly.
The bootloop is like this:
Screen: Shows 10 sec. sony-logo -> than 2 sec. black screen -> than 5 sec. sony-logo -> than it starts from beginning..
The bootloop-lenght varied until it starts finally into android.. sometime it doesn`t come to that point, and it reboots for a very long period (until I get annoyed and shut it down)
I have trying the following things to solve that issue:
- Flashing several stockroms wirh flashtool (D6503_17.1.2.A.0.314_Generic DE.ftf / D6503_23.0.1.A.0.167_Customized DE.ftf)
- trying to reset the hole phone with the xperia "emma" tool
- trying to reset the hole phone with the pc companion software
.. in my opinion, the problem could be find in the bootloader/recovery.. I don`t think it`s a hardware issue, because cyanogen mod is still runs without problems. Maybe some cyanogen remains are still leftover in the bootloader, that don`t work with generic android versions.. that`s what I can imagine. (but i`m not an expert
I don`t get why flashing the phone doesn`t solve the issue., it almost seems that the flash process don`t touch the bootloader, to overwrite it with stock parameters (?) or does not fix that area which is responsible for that issue..
Phone status at this time:
Not root - not unlocked - no backup of TA - DRM Keys (The guy that I bought that phone from, saddly doesn`t do a backup /
Before you flash the stock rom, are you clearing the Dalvik cache?
Whenever I've been through instructions on flashing roms, that always seems to be a step, but I didn't see you mention doing that before flashing.

Hello sir. I am in a big trauble with my samsung galaxy E120 k. It is rooted and running in cwm recovery. As it is a korian phone there are a few number of custom rom i found but non of them fully stable and 100% bug free. So i am running with stock rom with variety of customization by xposed module. But suddenly yesterday my lockscreen has vaniahed!! Not only this, in addition with this in every boot bluetooth automatically goes on and screen time out seted at 10 minute and most serious peoblem is powwr menu also vanished , holding power button leads to switch off directly instead of appear power menu where reboot, user profile, shutdown are suppose to listed. I can not solve this even after fully wiped data, reset factory setting and restored previously backuped stock rom. Nothing works. I tried every possible way i known. I searched google a huge bt got nothing.
Now plz plz plz anyone help how can i get rid of these problem. It is very urgent coz i im gonna sell this **** after resolve the problem. Plz anyone help me. I will be very very greatful to u. Thanks in advance and sorry for my bad english.
My i9300 seems to have lost control on (soft?) boot:
- I flashed a 5.1 omni ROM that made me very happy because really stable enough for me to use multiple apps at same time.
- One week after, I started getting unwanted soft reboots (skips Samsung boot screen), leaving me approx 40s of system use before 5s freeze followed by reboot.
- These soft reboots are weird: if I force shutdown (power menu OR removing battery), the phone boots anyway, by itself!! And I think this is still soft boot because it still skips Samsung boot screen.
Additional info:
- I wondered if my power button was messed up but I don't think so: I would not have this freeze before reboot, plus I have no reboot while in recovery.
- I saw some SMS problems: received one from my provider, and I kept receiving it again at each reboot (same one 50+ times). Any link possible?
What I tried without success:
- Remove SIM and SD card
- Remove battery for a day
- Change battery
- Re-flash recovery
- Wipe System + Data + Dalvik/Cache then install paranoid android (now I can't even boot in anything else than recovery btw)
I'm lacking android system knowledge but it looks like there is a location in "soft reboot zone" that is locked, and the phone keeps reading it and rebooting infinitely. Is there a way to clean this? To forbid soft reboot maybe? Note that I've been flashing various roms for 3 years on this phone and I never saw anything alike.
Any advice is welcome, thank you for caring !

That SMS thing is strange
Have you tried another recovery version? Or perhaps changing recovery? This isn't a normal issue, since you already tried installing another ROM.... You can try another Kernel either
If none of this works, consider flashing the original Samsung's ROM or some samsung-based ROM (they usually do a nice clean-up, at least for me these ROMs fixes the majority of my problems)
@blint6:
1. Maybe the hardware though. This you can test by flashing actual firmware and running it under normal conditions for 1d.
2. Reboot is a known reaction to RAM-lack on LP, too. Flash Omni cleanly and run it for 1d without GApps and bigger apps.
Hi,
I'm facing a strange Black Screen Problem even after booting of the phone successfully every time. I can see the lock screen every time for like 2-3 seconds then suddenly entering to black screen automatically if I try to unlock or don't attempt to do so. The phone is able to ring if I try to make a call from other no. but won't able to pick up because there is no option to answer or decline the call. If I hit the power button all power menu buttons are coming like to reboot, power off , airplane mode etc but some how I'm not able to access the phone from inside.
Please note that last time when the phone was running fine I saw one error like android.system.mui has stopped working and everything was crashing so I had to reboot my phone and ultimately landed into this issue. Also my internal storage was like 600-500 MB free that time.
I'm on miui 9 official for Redmi Note 4 ( 32GB version SD 625).
I'm a new member of XDA and I haven't read all the rules yet, so I apologies if I do any mistake please correct me if I'm wrong as this my first post in XDA. I respect all the community guidelines.
Please provide the working solution for this.
A few quick questions as follows
- Do I have to install TWRP recovery for the same to clear cache which i think it may resolve the issue just removing the cache?
- I'm not sure about Miui recovery 3.0 clear data option to clear cache as i don't really want to erase my all important documents, photos, videos, notes in my phone.
- How can I recover my data if I had to reset my device ?
Please guide me for the above issue.
I really appreciate all your concerns.
Thanks & Regards,
Gaurav Kumar
I have exactly same problem, please help with solution.

Are you able to boot into the recovery and use it? Or does the recovery shows the black screen also?
hey I`ve just got the same problem in Redmi note 4, did u find any solution?...
so far what i did till now is, flash Red Wolf Recovery, wipe, DALVICK, CACHE and DATA (not the internal storage where is your info), the wipe is like a factory reset, is the only solution I`ve found so far.
any ideas?

Do you have a unlocked bootloader? If you don't then possibly resetting device from recovery is the only thing.
Does this issue already solved? I also have the same issue but I don't know how to fix it. Please help me
HI
I have the same problem, I tried using the fastboot (power+volume down) and nothing happened, I tried the recovery mode (power + volume up) and I got three options, (reboot, wipe data, connect with mi assistant) the first would reboot the phone to the same problem, the second one I don't want to wipe all data or reset the phone as I want to retrieve the data on it, I tried the third and downloaded the mi pc suite, but the phone doesn't show on my pc, I receive the no device detected even after connecting my phone with USB
I have the same issue on my Mi Max 2!!!
And the developer mode isn't possible to enable, because of this black screen!
Please help!

I updated my Mi Note 4 system software yesterday to MIUI 9.6 (me thinks), but it is having booting issues. I struggled 2 hours last night to get it started but in the morning I noticed that the fingertip sensor isnt working. I cleared cache, added new finger print, still the problem persisted and then I read on the forum to power off and restart the phone. I clicked on power off and since then my phone is not rebooting. The screen in black, I can hear phone calls, msg notifications. I have tried pressing the power button for 40 seconds (as per the MI Support Tech's advice), followed by using the fastboot (power+volume down) and nothing happened, I tried the recovery mode (power + volume up). Still nothing is showing. The Mi logo and android restart option isn't showing only. The phone is black. I can see navigation light and the blue light blinking on the top left when msg/notification comes. I haven't taken a back up since many many months. I don't want to lose my data. Please help.

Why don't you throw your data in a PC or a memory card? Also guys if im not mistaken you can not rollback from MIUI 10 to an earlier version if you update via the OTA right?Or else your phoned will be bricked am i right? Someone confirm this cause its risky.
Solution for mi black screen.
Hello friends,
I think the issue in sensors, because when i bump my mobile on my hand the screen wake up suddenly but some time screen in hang position but when i try it one or more time its working normally .
Same issue
Hi, I recently updated to the 9.6.2.0 in my Mi note 4 and after reboot it started to go off and on (only the backlight (touch layer worked)). I rebooted several times and get it going. after few minutes went black again and after reboot the fingerprint sensor stopped working (HW diagnostics saying error if you try to test it) and then the battery status started act weir. If i plug phone to charger, no matter how many % i ve got it charge only 1% (after hour or so)and if i unplug it lose 5% in 5 seconds and stays there for amount of time till the battery reach the same percentage as the indication is sayin.
TBH pretty weird and pretty annoying.
And yes it is probably sensor ( or a driver? ) because turning phone up-side down or covering the proximity sensor osometimes help.
I dont want to wipe my phone until it is necessary.
Is it because of update?
Thank you
