[Samsung A8] Phone UI won't boot after changing DPI - Galaxy A3, A5, A7, A8, A9 Q&A, Help & Troubleshoot

Hi guys,
So I was messing around in the developer menu settings (big mistake) on my galaxy A8 when I found an option to change the DPI of my phone. I changed the value from 360 to 800 and inmediately a 'UI stopped working' message popped up and the whole screen went black. I quickly restarted my phone but the boot up animation ends everything is still black (if i a hold the power button a very small version of the Power off, Restart, Emergency alerts show up but they are not responsive). I had not enabled USB debugging before, and I tried to make a backup with KIES but it won't work since it says the phone screen is locked.
I looked around on some forums and found out adb, but all the methods involved having USB Debugging turned on (since adb does not recognize my phone).
Everything on my phone is stock and android version was up to date.
Is there anything you guys think I can do? I have a lot of info I would hate to lose on that phone :crying:

I'm just kidding. Learn how to put your phone in download mode and download Odin and your firmware and flash your firmware in download mode in Odin (on ur computer)

Almost gave me a heart attack :laugh:.
Thanks for your reply! So I already have Odin installed and I'm currently looking for my firmware. I noticed that most have country name followed by a phone carrier. My phone was factory unlocked, so I guess this should be the one? sammobile.com/firmwares/galaxy-a8/SM-A530F/BAT/ (can't post a url since I'm new here)

Flash didn't work?
I downloaded the XEU firmware for my phone and followed the steps to flash it. Odin gave a PASS! message, but it took a really short amount of time (0:02). After that it rebooted the phone, but after putting my password the screen went black again just as it did before. Did I do something wrong? I used the HOME_CSC since it said that it wouldn't wipe my data (I haven't been able to make a backup)

Because you flashed the HOME_CSC version, the system ui was also saved, therefore dpi changes stayed with the new stock flash. I don't think you can get your phone back without losing data.

[Q] AT&T S4 wont turn on. Only vibrates.

Ohh, where to start. Ok so first off let me apologize in advance if this has already
been posted but I’m a noob when it comes top posting in the forums. Been using
them for years to fix my problems just new to posting. Anyway, a few nights ago I
tried to flash the newest version of the T-Mobile AOKP rom (Kit Kat 4.2.2) onto my
AT&T I337 Samsung Galaxy S4 via the latest version of TWRP recovery. After
attempting to flash AOKP, TWRP failed the flash and had an error message that said
something about the phone not being able to flash a T-Mobile rom on an AT&T
phone. I then tried to flash the AOKP rom again and mistakenly flashed the Loki
kernel instead. I was currently running Cyanogenmod 11. After the Loki kernel
attempted to flash, it once again said failed and gave me a message that said
something about me losing root and asking if I wanted to reinstall superuser. I
agreed to reinstall superuser and used the option to reboot my phone once it was
complete. But….once the phone attempted to reboot my screen went black and all
my phone would do is vibrate every two to three seconds with a blank screen. I
pulled the battery, tried to put it in recovery mode, and download mode but nothing
worked at all. It wouldn’t charge, no battery icon, no LED. After messing with it for a
few hours and randomly pushing buttons I finally got it to go into download mode. I
was so happy. I decided I would flash (Odin) a stock firmware that I had already had
and used plenty of times. But…after flashing Odin would say complete and pass but
when my phone would reboot it done the same thing as before. Black screen and
vibrates every two to three seconds wont charge, no battery icon, no LED, still won’t
go into recovery mode but will still go into download mode. I’ve used every version
of Odin, used different USB ports, different USB cords, reflashed the stock at least
20 times now and still nothing. What have I done and how could I fix this issue. :crying:
Ohhh and before I forget, It may be worth mentioning that when I finally got it in
download mode I noticed it said that I had the stock Samsung firmware, where it
usually says custom when rooted.
I'm assuming you're on MDL firmware. If so Odin flash the stock firmware. You can get it at sammobile.com
You're probably hosed though, sounds like you've tried all this.
Doesn't work

First observation: nothing here says that he fixed it. If he did, which may not have happened, then he obviously didn't tell us.
I wonder if you really have the same issue. Did you read through the OP? Did your phone get where it is by doing the exact same sequence that he did? If not, and you want someone to help, you will need to give a detailed description of everything that led up to the issue you have, from the time the phone was operating normally. It would also be helpful to know what your phone was running before this happened.

[Q] Help a Noob please? Flashing the Stock ROM won't work

Hello, I am new to these forums as well as owning an Android device, and was directed here from Reddit when I posted my question there. to save time, I'll simply copy/paste my explanation of my predicament from Reddit, but if I seem to be leaving something out, please tell me so I can offer up as much information as I can.
"I've owned a Galaxy S5 for a little over 2 weeks, and for the past 4-5 Days, any time I try to Turn it on, I receive a message that says "Secure Fail: Modem", in red letters at the top left of the screen, and in the middle there is a yellow triangle with an exclamation point with the following text underneath "System software unauthorized by verizon has been detected on your device. please shut Down and go to the nearest verizon store" I'm 17, and currently staying at Governor's school, so I didn't have a ride until yesterday when my Dad and Uncle came to help me try to fix my phone. We went to the Verizon store, where they said that it looked at though I had tried to "root" the phone, which I haven't. My theory is that this is the result of a pokemon game I downloaded from the internet for an emulator. We Called tech support who couldn't help us, but after a little Research, I tried downloading Odin and flashing it with the Stock Rom, but every time I do that, I get the same Error message, regardless of whether I wipe the phone first, or Remove the sim card or whatever, so I don't know what I'm doing wrong and thought that maybe reddit could help me."
I've tried to flash the stock rom several times as per the following video: apparently I cannot link to outside content; however, the video is titled "How to Flash Stock Firmware for Galaxy S5 [All Variants] by Odin3" on youtube
if anyone could help me I would greatly appreciate it.

Restart your phone in recovery mode by shutting the phone down and then starting it back up by holding the home, volume up and the power keys until you see the blue text at the top of the phone saying recovery booting. When it boots into recovery use the volume key to select wipe cache partition and then press the power key to run that. Then select wipe data/factory reset and run that. When that's done select reboot system and see if it starts normally. If that doesn't work try Odin with the tar and pit file.

I've tried all of that, even the pit file, it's still telling me that it detects system software unauthorized by verizon, and I don't know why or how it would if I've supposedly wiped the phone clear several times over

I use this method and it worked great. I suggest you try it again, to include re downloading the tar file. Follow the straightforward instructions. Leave your phone connected to the computer even after you flash the tar. It will go through the whole reboot process while connected to the computer. If you still have problems, ask mrxtc (op). I see him all over the place and he seems pretty good at helping people fix problems.

everything I downloaded was from the google play store, with the exception of the "pokemon emerald" rom from coolrom.com. I hadn't attempted to root the phone prior, I didn't even know what that meant until I googled the error message. that actually brought me to a thread on this site where somebody had tried to root their S3 and got the same message. as for the model of the phone, all I know is that it's an S5 and that I got it at Verizon.

Other than what I posted in the recovery thread and what I posted a few posts up that's pretty much it. You could try the nand erase all and efs clear options, check the screen shot and make sure your check boxes are correct. Also if you didn't download the files from the thread I posted I suggest you do. Honestly if none of what was already suggested doesn't work I would contact Samsung. I've had and seen your error before and successfully reset my phone before.

i guess my question was how did you try to run the rom? its a long shot but thinkin since technically its a rom file maybe you used it wrong.. also, theres dev edition s5 and retail s5 for vzw so it does matter which model you have and which odin files youre trying to use.. since phone is less than a year old, id contact samsung if you cant get it fixed and theyll send you a return kit and reflash the software for you.. something similar happened to someone with an s5 active on att n samsungs gonna help him.. only reason he needs to send it in however is cuz there is no s5 active tar available yet for him to odin. you should b able to on yours but hard to fix without having the device in hand and u saying uve tried everything

theres a soft brick (recoverable) and a hard brick (not recoverable).. normally a hard brick your phone wont come on or go into any mode at all.. soft brick is when it starts up but either bootloops or wont boot at all into the os (like yours).. im just lost as to why it wont work! crazy.. if u got at vzw and dont know what a dev edition is then u most likely have a retail s5 so mister odin guide should work..

The only way I can do that is to get the phone to boot, which it will not get past the error stated in this thread: "SECURE FAIL: modem" I just tried to get all of that to work (sorry the late response was at work) and again it's a no go, I'm going to take it to Verizon, but I'm not optimistic about what kind of results I'm going to get there.
The phone came with the NI2 SW to begin with, and I tried to install that with Odin. gets me about half a second of the normal Samsung splash screen then straight back into the error, after that first boot, no splash only the error.
Thanks for the suggestions though.

Bricked S5 SM-G900F, cannot boot to recovery

Firstly my thanks to all the experts here - I'm a complete noob, yet I've managed to use the threads here to install a custom ROM on an old Sony Experia and more recently my Galaxy S3.
However, my S5 is sick and I'm stuck. Sorry to start yet another thread on this topic, but they mostly suggest things I've tried and in any case my head is spinning with it all so I'm starting afresh.
History: I was using the S5 as normal (RealCalc, IIRC - nothing exotic) and it became a bit non-responsive, so I restarted the phone. It hung at the 'Samsung Galaxy S5 powered by Android' screen. Tried again, same; took the battery out and tried again, same.
After much Googling and searching here, here's what I've tried:
Used Odin (various versions) to flash a recovery (can't remember which one). It appeared to work but on booting into recovery (power, home, vol-up), it hung at the 'recovery booting' screen.
Used Odin to flash a TWRP recovery. This gave me 'recovery booting (blue), recovery is not seandroid enforcing (red), set warranty bit: recovery (yellow) but still hung.
Eventually, after several attempted flashes, it booted into TWRP; the first thing I thought I should do was take a backup. It was late at night, so I left it backing up to the SD card (connected to USB power). In the morning, the screen was saying that the backup had completed ok, but the phone was completely frozen. Since then, it's never got past the initial boot screen
I also tried Odin to flash a stock ROM obtained from SamMobile. This failed right at the end (FAIL! (Ext4)).
I found a PIT file for the 900F, and with this and the stock ROM, got Odin to a PASS at the end. However, it still hangs on reboot.
The only thing that seems to work reliably is getting into download mode and flashing with Odin, but it never boots after that. I've tried other variations of the above but foolishly I didn't take notes and in any case they all had the same result.
Completely stuck. Would very much appreciate any suggestions.
Did you try flashing custom ROM?

No, I did download a CyanogenMod one, but I can't install it from recovery, as I can't get into any recovery now.
Are there any custom ROMs that can be flashed from Odin?
did you try to remove and format your extSD (possibly partly corrupted) and reinsert and flash again? Or change to other extSD?

Well, I removed the card completely and reflashed with Odin. No difference.
I can't flash from a ROM on the SD card because I can't successfully boot into recovery.
I suppose, you already tried to flash twrp-2.8.7.0-klte directly from here: https://dl.twrp.me/klte
and latest stock rom for G900F and your country directly from here: http://www.sammobile.com/firmwares/database/SM-G900F/

I have, yes.
And earlier stock ROMs, and with earlier ODINs too, in various combinations.
Every time, the flash appears to work but it then hangs, booting into recovery. I get the blue 'recovery booting' line at the top, on the Samsung initial boot screen.

It was late at night, so I left it backing up to the SD card (connected to USB power). In the morning, the screen was saying that the backup had completed ok, but the phone was completely frozen. Since then, it's never got past the initial boot screen
I also tried Odin to flash a stock ROM obtained from SamMobile. This failed right at the end (FAIL! (Ext4)).
I found a PIT file for the 900F, and with this and the stock ROM, got Odin to a PASS at the end. However, it still hangs on reboot.
The only thing that seems to work reliably is getting into download mode and flashing with Odin, but it never boots after that. I've tried other variations of the above but foolishly I didn't take notes and in any case they all had the same result.
Completely stuck. Would very much appreciate any suggestions.

This video just shows starting up in download mode. Not sure how this helps. I can do this, flash a stock rom or recovery with ODIN, which appears to work (get PASS at the end).
Then on reboot to recovery, it just hangs at the Recovery booting message.

Appears to be, as I've said. It's the reboot to recovery after flashing that hangs.
I don't have access to a working G900F, unfortunately.
Well, it turned out to be hardware. Needed a replacement board, seems fine now. Thanks for the various suggestions, but none of them worked.

wow you have an identical problem with my device. Did you go to samsung service center or a unofficial service center? and may i know how much you spend to fix that? i'm afraid it'd be expensive for a student. thanks before.

I took it to a local (I live near London, England) Samsung authorised service centre and they replaced the board.
It cost me GBP 169... :crying:
Worse still, it turned out that it had a 2-year warranty, not the one year one that I thought it had. If I hadn't tried to reinstall Android, thereby tripping the Knox counter, it would have cost me precisely nothing...
An expensive mistake there - check your warranty carefully.

My warranty isn't valid since i bought a mint condition second-handed G900F from SG. I'm Indonesian. My knox is 0x1 today when i tried to fix that using boot.tar (i didn't know if it'd make my knox avoid! desperately tried every possibilities. Ended up sobbing to see that 0x1).
I thought the problem is on the software, not the hardware. So i'm bit shocked reading your statement that you replace the board. Hope the local service center near the city helps. Thanks for the info!

Well the thing is, flashing a new Recovery and booting into recovery mode isn't difficult - I've done it several times with other phones, and it's a straightforward procedure.
So the fact that the phone wouldn't boot to Recovery was (in retrospect at least) a bit of an indication that all wasn't well with the hardware. I wasn't messing with the phone when it failed initially, either - I was just using it.
Booting to the stock recovery was the first test I did on the repaired phone, and it worked fine. I'll be leaving the ROM as stock, though, till the warranty runs out.
A bit strange for the board to just stop working though - I've looked after the phone very carefully since new.
Is it common with the S5, does anyone know?

Er, did you read my earlier posts? #14 and later.

I think I bricked my Android phone, is this normal?

I attempted to root my phone (Samsung Galaxy S7 Edge) following this guide here
http://forum.xda-developers.com/ver...-to-notes-root-install-xposed-unroot-t3411039
After this step "Still in Odin, click 'Start' to flash the engineer-rooted boot image and reboot the phone."
My phone just hangs on a white screen with the AT&T logo in the middle. Its been like this for over 5 mins and I'm not sure if this is normal or I should wait longer.
I did a restart by holding power and volume down and it still gets stuck on that screen. What can I do from here?
Did you follow the guide to the T?
What version of ODIN did you try? The PrinceComesy version, or the regular one? Did you try again using the other version?
Note: most people use the PrinceComsy version, but some AT&T users said the other version will prevent bootloop/stuck AT&T logo.

I tried the PrinceComesy version, I tried to use the first one but it wouldnt open for some strange reason. I'll try that first Odin, I have a S7 Edge and I downloaded the 2nd one like I was suppose to. I honestly dont know what part I fell short on.
Everytime I try to open that first version of Oudin, some popup in Korean shows up then it closes instantly.
If I cant fix this am I gonna have to do a factory restore? I unfortunately did not make a backup beforehand.
My phone is still in a brick like state for the last 3 hours, is there any way to recover from this if I dont have a backup?

Download your original or latest firmware using samfirm on the s7 edge threads and flash all 4 parts but use Home_csc file. This won't erase you're data and help you unbrick. You can then start again on rooting.

From the same rooting topic There is stock firmware for Android phones, since I own a Galaxy S7 Edge I downloaded the (ATT_G935AUCS2APF2.zip (MD5 hash BB4904F9D6E730F23AE0DC727AC87752) (AT&T Samsung Galaxy S7 Edge))
It has all 4 parts like what ODIN asks for but I'm confused on what your asking me to do exactly when you said "flash all 4 parts but use Home_csc file"?

Looks like you've got no choice but to flash it then mate. I have a G935F so have two in our firmwares sometimes. At least it means a working device once flashed.

Have you tried booting into recovery? Hold power, home and volume up or if not possible then use volume down as you would boot into download mode but when phone resets quickly slide your finger onto volume up and hold until into recovery. Clear cache and reboot.

I tried what you said and recovery mode definitely works. However I wipe the cache partition then did a reset and I still get stuck on the AT&T screen. Where would I get that home csc file in the first place, was it suppose to be among those folders with all the other models and carriers and mine is just the unlucky one that doesn't have it?
Any other ideas before I take the plunge and wipe my phone?
did you perform a hash/md5 check before you flashed? also verified size was IDENTICAL?

That's the cache wipe option done. Because you have the ATT version then you would only have one csc file. G935F has multi csc files for multiple regions so we usually have two. Take the plunge just to have a working device. Recovering your device hopefully.
I don't think you bricked, but certainly you flashed either the wrong firmware for your device, a corrupt download\firmware or you removed the phone prior to the flash completing, which could be due to faulty cable.
I would download a stock firmware and make 100% site is for your device. Make sure it's the right size and then flash ensuring your cable between the phone and PC is in good working order as well as the USB port on the PC.

Alright so I'm gonna make a backup so I dont start from square one again (I was without a phone for a whole day)
When I restored my phone using that "stock" firmware I noticed something odd when it boots up, it says "samsung galaxy S7 Edge custom" and shows a lock thats unlocked.
Anyways if I'm unable to open that first Odin (korean pop-up and immediate shut down) and that prince version is not good with AT&T phones what other choice does that leave me to root my phone?
I'm gonna take my phone to best buy and have it restored. The restoration from here is weird and is giving security issues, not to mention my wifi doesnt ever seem to save for some strange reason.

J500F two problems, recovery screen is corrupt, custom roms will not boot.

Hello all,
I've got a couple of problems with a J500F. As usual, I rushed into doing things to the phone before reading fully (I've been installing various ROMS on my phones for quite a while now).
First of all, I've managed to install TWRP 3.0.2-0. But it seems that the calibration of the screen is way off what it should be. Clicking the "Install" button actually registers as the "Advanced" button. So I can still do things, I just need to guess where to click. Anyone else had this problem?
Secondly, every ROM I try and install will not work. I get a couple of horizontal lines across the screen, and nothing else.
Any help/suggestions are more than welcome.
Thanks in advance,
Tony.
Tony only tme you should panic is you mess efs . If you hve stock rom flash it via odin this would solve ur calibration issues. And install nickverse version of twrp maybe you installed a version for 6.0.1 instead of 5.1.1

Go and try sammobile or google it ull get it make sure to flash it through odin. Am sure you will be fine. Download the right firmware according to your country and region send me ur device name and region i see if i can share a download link

The model is SM-J500F/DS, and it's a UK phone. Sammobile does not seem to have any UK image, I'm wondering if it actually came from somewhere else (I purchased it on Amazon UK, but it did not have a UK charger).

Go to settings then send me screen shot of about phone. You can download an app from playstore called Samsung phone info(something like that) can tell you which region its from...

I cannot get into the settings (cannot get a ROM to boot).
I've just tried the Nick Verse recovery, it continually reboots the phone unfortunately without ever getting to the recovery screen.
I'll try one of the European ROMs from Sammobile, hopefully that will get things working again.
ok, I've got a stock ROM on the phone and it's booting up. But the screen calibration problem is still there which makes it unusable.
Going to see if I can use the app on Google play (not sure how I'm going to connect to the wifi though).

You need to enable oem to unlock ur bootloader then you can flash twrp. Ensure that usb debugging is on. You might hve missed one of this two

I'm guessing you probably need to upgrade your rom. Strange lines and out of whack touches are usually due to an incorrect firmware vs kernel.
Ensure you are flashing the latest MM rom for your device if the TWRP you are using was built using a MM kernel.
Try flashing stock via Odin. Guides are available all over XDA on that.
I'm just getting back to this.
I've shot a quick video to show what I mean is happening.
https://www.youtube.com/watch?v=yR5dF9lURcU
Jump to 10 secs, you can see that click location is way off/.
Anyone got any ideas? I've flashed a number of stock images so far, all have the same issue. I've currently got a mouse connected via bluetooth so I can actually do things as trying to work the keyboard like this is impossible.

Are you actually allowing the firmware to complete its update?
It must boot into recovery after odin finishes flashing otherwise the install isn't complete.
It should auto reboot to recovery and you should see 'erasing'
Then it will reboot and the update should be completed.
If it does not boot to recovery then this is likely why you have the described issues.

Yes. I've just reflashed to check. It downloads the image to the phone, reboots into recovery where it says erasing, installing system update etc. Then reboots and I get the "Android is upgrading" message where it does all it's "optimizing apps". The touchscreen error still persists .
I did video this (or portions of it) and can upload.

Which firmware are you using and what is your device spec?
I've got a few ROMs that I've tried
SM-J500F_20160812_J500FXXU1BPH1_J500FODD1BPH1_6.0.1
SM-J500F_20160512_J500FXXU1APE1_J500FOXX1APE1_5.1.1
J500FXXU1BPF4_J500FODD1BPF4_SLK
Same behaviour with all of them. I'm not entirely sure what region the phone was originally from, I purchase it on Amazon and believe it came from somewhere in Eastern Europe, so I've been trying images marked as Austrian, Slovakia, even Greece.
If it helps, the following is under the battery.

Install Samsung phone info and post a screen shot of the CSC info.
It should show your original CSC.
Thanks, I've uploaded the screen. Sorry it took so long, I've been away and forgot the bluetooth mouse that I use on the phone.
It looks like the original CSC is SM2J500FZKDAUT, I cannot seem to find that on Sammobile.
