[Q] Unbootable green and red pixelated screen on boot and CWM6/5 load

So just to state the lead up to the unbootable phone.
Condensed version:
Flashed to Bio360 (ONLY working rom that was running for me thus far)
After a week of use, phone would boot for 5 seconds until screen turned pixelated
reflashed but did nothing
flashed to ICS using download mode again and worked but with limited function as when I first flashed ICS before Bio360
flashed using CWM6 back to Bio360 but still same problem
now will not boot into CWM6 and gets the pixelated screen either way
WILL go into download mode so I tried a few more ROMs to hopefully write over whatever issue there is with the software but nothing
reflashed using ODIN the CWM to 5 and 6 but same problem (will not load to CWM at all now
tried a few more times in the precise order as the first time I ever got the phone working with Bio360 (STILL a messaged up screen)
More detailed account of things:
I originally tried updating to the ICS upgrade a few weeks ago but got stuck on the boot screen and other issues. I finally flashed the CWM6 and updated the rom via that to the Bio360 rom. I finally had a working phone again after countless hours of trying to get it working. I locked my screen after timeout to a pin number but actually found it was a pain in the behind so tried to switch back. However I used the 'settings' feature which was present on the home screen after boot that comes with the Bio360. Then I deleted the icon an could no longer find the one that I was originally using, but found the other newer icon in the applications. So I took the lock feature off. Though it did nothing and the phone still required the pin. I tried changing it etc etc etc and nothing worked.
So, I flashed the Bio360 rom again and tried to start fresh, only to find that most of the settings that I originally were using before the re-flash were still present. This lead me to believe the settings are not completely wiped and flashing through CWM6 does not do a pristine clean update. Then I read that I should have to clear any and all settings by factory reset, clear cache, partition or whatever other clear functions I found within CWM6. So I did that and everything was back in good order again.
That is until I woke up 3 days ago and found my phone 'bricked'. Not literally as I am told it is almost impossible to brick one of these. Upon rebooting the phone I found that it was booting to the Samsung logo and after about 5 seconds, the screen becomes pixelated with red and green colours, sometimes lines all over. The longer I leave it, the more the screen becomes a wash out.
So I tried flashing the rom again using CWM6 hoping this would fix, but the same thing occured. So I tried to use CWM5 hoping that would fix it but still the same. I tried flashing back to gingerbread, then ICS, then Bio360 as I originally did to get the phone working with Bio360 but the only thing that I can do now is boot into download mode. Anything else causes the screen to become pixelated and wil not boot past the messed up screen no matter how long I leave it.
I searched for other threads but only found threads based on a single large pixel or a physically damaged screen. However, the screen is still functional as when I boot to download mode or just before the screen becomes pixelated, everything looks great. Plus there was one time when I flashed to ICS I got into the blank screen with limited functional capacity as when I first flashed ICS and the pixelated screen disappeared. So this leads me to believe this is a software issue.
I believe that there is an issue with files being left behind that are corrupted or something similar but I cannot even boot to CWM in order to clear everything possible.
ANY IDEAS? I have explored every option that my limited understanding of software could.

picture of what it looks like
This is a crappy picture from my old phone of something like what it looks like.

This is a capture after it was turned off even and I plugged it into my computer, displaying the battery charging animation, though turned pixelated after a few seconds.

My gut says hardware damage, like something inside the Tegra itself is fried, ESPECIALLY since it's happening sometimes while still in the bootloader (charging animation).
Try Kies emergency recovery. If it flashes successfully but still won't boot, or glitches out like this during the flash, you'll have to start the RMA process.

I am unsure if it would be a hardware issue though since the screen is fine during the 'download mode' and did boot into the stock recovery after a flash a while back, then flipped back to not getting past the Samsung logo and pixelating again.
Would I be able to load the download mode portion of the phone if it was a hardware issue?
I ask because my gut says the opposite.

flashing CWM 6 causes my phone to be unbootable and pixelated screen
So, I have tried to update the phone into whatever other ROM that I can possibly get working only to find out that after flashing a ROM that flashes the original recovery program included with Android, voilà! The phone works again and boots into the black screen with pull down menu. Back to square one for me.
Why would CWM6 be causing such a thing?

I'm on CWMR6 since the begining without any issue. Did you flash the touch or the non touch version ? Also whcih odin version are you using, maybe that makes a difference. The 1.82 and 1.85 are tested to be working fine with both cwmr 5 and 6. Also by reading your thread is seems you've never been able to flash through ICS one click, if possible try doing that.

I have been using the cwm5/6 touch and non touch. I have tried flashing them both. I have been using the most suggested version of ODIN 1.85 to flash. I do not think that it would make a difference as to which ODIN version I use, but then again I am quite ignorant on software.
The first thing that I did was tried the flashing using the one click method. I could only get to a black screen with the pull down menu containing the turn wifi on/off etc. I read that the problem may be permissions but I have tried that using the CWM when it worked and I was still stuck at the black screen with pull down menu. Without CWM I have no way of doing anything really since everything is in zip form and without CWM you cant use the zips.

Well then probably a logcat output to a developer would help understand the problem you're facing. Find some knowledgeable developer who can help you read the logcat and find the issue. Or post it here and maybe somebody would give you a clue.

I have the same problem, i bought mine in ebay, (i live outside USA so i cant get money back) my problem start when i try to install a apk, then, i try to restore with wipe in cwm (sometimes works, sometimes no) and eventually, only download mode work. I dont know what i do, but in one of my trys, ICS 4.04 works everything, but i was network lock,i try to downgrade to Gingerbread and the problem come back, i dont know what to do, i feel like i waste te money.
PD: I have the roger version
EDIT: I just flashed ICS from ATT And works, but i w ould like to root and i cant, every time that i flash CWM, the problem come back
EDIT 2: I use the one click to install ICS from att and works, its seem the problem is when i use a custom rom or the CWM, dont know why, its seems that is not hardware because ICS works perfect, but Every custom rom or CWM, cause the problem
Maybe is there a way torecreate all the internal partition, i dont know, or something like that, to make a clean install, I am starting to regret for buying this phone, maybe the problem is because is from rogers (a security rule maybe?)
Sorry for my english

Ok, i learned something, when a flash the Gingerbread version, there is a error while booting (the first time that boot lik recovery) , the error is can't access to /system/csc/ATT/system/
When i use the ICS from ATT, that doesnt happen, maybe that is the problem? i dont know, maybe someone can tell us what are these files

[Q] Getting "Firmware upgrade encountered an issue" error but boots fine

Recently I started getting "Firmware upgrade encountered an issue. Please select recovery mode in Kies and try again" whenever I reboot or boot to recovery. Searched on google and xda as well, but whoever had this problem, their phone never booted. But my phone boots fine when I press and hold the power button and working fine as well . Currently I am on DN4 but I had this problem on other ROMS as well. Is it going to be a problem? Do I need to do something?

Nobody has the answer?

???

Since you are on a Custom ROM, you can safely ignore the issue.
What happens is Samsung checks your Device for the Firmware version that has been loaded on to it. And Samsung already has the hardware details with it (since it manufactured that device) which you show it to be a Note 2.
However you have modified it to be a Note 4.
So Samsung gets confused because this is also a Samsung firmware running on a Samsung device and it is not the proper version. Therefore your software throws this error.
If it was a Note 2 with stock firmware, then you would not face this error else you will always get an error while trying to check for updates with a ROM other than the stock ROM.

Yeah I got that but I was getting this error even on older versions. And like I said, whoever had this problem had a soft brick. Anyways thanks. As long as it works, its fine.

Yes,
But you always know how to recover from a soft brick
But I don't think you will get softbricked. Its just some messed up service gone haywire. You can greenify / remove it 8f you identify the culprit.

SM-G925F Stuck at factory reset, unable to enter the recovery mode and flash firmware

Hello and sorry if this is the wrong category...
It's my first time making a thread on xda.
I've been looking for an answer for the past 2 hours, but I still have a bricked phone... As the title says, I can't enter the recovery mode anymore. I tried to do a factory reset (when I could enter the recovery mode) and the phone got stuck at erasing. Now I can't enter the recovery mode anymore. I downloaded a new firmware from sammobile for the SM-G925F. The firmware works since I used it on an other phone and everything worked just fine. The problem is, when I open Odin and add the .tar file to AP, it gets stuck at nand write and sometimes on boot.img. The phone isn't showing that it's downloading anything (it has no progress bar). At this point I have no idea what to do...
Some extra info that could be helpful:
The phone was bootlooping when I got to fix it;
I work in a kind of phone repair store where customers bring their phones for hardware and software repair. I do the software;
I've installed new firmwares on multiple phones and I never had something like this... Normally some time with google and xda could help me to find a working way to fix the problem, but as I said... I've been looking for 2 hours and the problem is still here;
I'm not a pro with Android and phones. I just like to learn new things and I'm still learning.
Could it be a hardware problem?

Can you show me your phone's download mode image to see where could be the problem?
Also, make sure you are flashing latest firmware, if you are downgrading it - than you will get such boot errors.

*Update*
I found out what was wrong. The eMMC chip was broken.

Bootloop without solution? happened suddenly

Hi everyone.
I have been reading a few posts about bootloops in hopes that someone would have been facing the same issue as me. It seems my case is a bit different. I am desperate for some help!
My Max 3 came initially with a chinese ROM but I followed some wonderful tutorials here and I unlocked it and installed initially the xiaomi.eu ROM. Then a couple of months later I installed AOSiP ROM, I updated it a couple of times dirty flashing over it, and settled in exactly the "AOSiP-9.0-Pizza-nitrogen-20190719" build. And there i was, for 4 months, all stable, then suddenly today I was going to unlock the phone with my fingerprint and asked for password.
This happens exactly 1 time per day but I noticed that today it was the second time. Then doesn't matter how many times I put my password correctly, it would keep asking for my password. So I decided to restart the device... and then the bootloop issue started. It starts, reaches the moment in which the AOSiP logo shows and (not even 1 second until the logo shows) freezes, and restarts the device.
I can access the recovery without issues so I didn't panic yet, I backed up all I could, wiped everything I could, started from zero: firmware 9.9.3 + AOSiP-9.0-Pizza-nitrogen-20191117 + gapps. The bootloop still there, in exactly the same way. So at this point I have no clue what could be the reason. I was always careful not to trigger any anti-rollback, it was all going good, now not even with a full factory reset seems to work. I even reinstalled the recovery.
Any ideas? does anyone know what could I try next? Thank you very much advance.

I forgot to attach some logs. I got using the TWRP Advanced > Copy Log option.

Well, I guess I completely screwed it now. I had the brilliant idea to go back to some of the original steps I did way back and flashed an old xiaomi.eu ROM "xiaomi.eu_multi_MIMAX3_8.8.9_v10-8.1", that completely bricked the phone. Screen doesn't even turn on anymore. Is it the end for my Max 3?

The mi max 3 has arb enabled, so flashing old rom can cause it to brick.

Have you tried different button combinations to enter fastboot? If you can get to fastboot, just flash a fastboot rom, if that works.
If the brick is caused by triggering ARB, then that may cause some issues, and may need an Authorized Account to flash the ROM from scratch, with some qualcomm flashing tools things.
Though, there may be some way to bypass the authorization for mi max 3 on the internet and have your device unbricked.

Thank you for your replies. Yes probably ARB, I thought my phone had never installed a ROM with ARB and so I was safe to install xiaomi.eu_multi_MIMAX3_8.8.9_v10-8.1 (which it is also to be pre-ARB), but I guess I made a mistake at some point.
Situation now:
- with Mi Flash I am getting the authorization error with almost any ROM, with very old ROMs I am not even able to start the flashing process
- with Qualcomm QFIL tool I always get an error "function: sahara_rx_data:237 Unable to read packet header. Only read 0 bytes". And I also tried with the patched files from here https://forum.xda-developers.com/redmi-note-5-pro/how-to/fix-arb-bricked-device-qfil-t3841780
I think at this point I tried everything that can be tried. My bootloader was unlocked, but at this point I am not even sure if its unlocked anymore since I can't see anything on the device screen.
The only positive thing is that the phone always shows under the Windows 10 device manager "Qualcomm HS-USB QDLoader 9008", so at least is a bit alive, and with the Mi Flash at least for some ROMs starts the flash process. I am not sure if disassembling it and trying things like removing the batter would make any difference.
If anyone knows any other way to bypass authorization please let me know.

Here I am back with another update:
- I fixed the full brick by disassembling the phone and disconnecting the battery, with the battery disconnected I could finally flash a Chinese ROM. That however was just the beginning... more problems came
- Common problem I guess is that after booting with that Chinese ROM i was getting a message about how the encryption was interrupted. This was easy, just changed the file system of Data and formatted it and it was fixed.
- Now I am stuck in another hard to solve problem. Any ROM that boots will not allow me to use WiFi or SIM cards. And the reason is that the IMEI is not set anymore. Reading about it I see that this is related with the EFS partition being corrupted. Nothing seems to work now. I don't have any EFS backup . Anyone knows how to fix the IMEI in this case?

Help Needed - Bricked

Before I get going - yes I know I messed up. I do have plenty of experience flashing ROMs etc, albeit I'm absolutely not an expert. This was purely a not thinking moment.
So I flashed my Samsung Tab S4 with Kali Nethunter a while back, not really used the tab since. Without a great deal of thought, I decided to put the device back to factory. I went back into the OS and flicked the OEM toggle - utter braindead move. Obviously the device now comes up with a warning, the exact wording is:
"Security Error: This device has been flashed with unauthorized software & is locked. Call your mobile operator for additional support. Please note that repair / return for this issue may have additional cost"
I can still access download mode.
Right, now you've finished laughing/cussing me I did some digging and apparently I can still flash with Odin if its the official ROM? I went to SAMMobile and downloaded the latest ROM and Odin fails with a write error.
What I need to know is:
How bad have I messed up?
Is this recoverable?
Any help appreciated.

Hello there,
So yes, pretty bad mistake but these things happen but it should be recoverable. Just follow the link to get your device booted up! Hopefully the link is for your variant, if not look into installing twrp recovery for your device. Once installed you can back up your data and flash the rom compatible using twrp. Then set up the device and restore your data but make sure it's unlocked or your error may repeat itself! Also you have to find the right version of Odin, they do vary some are patched. Have fun!!
Recovery

Hi,
Thanks for the reply Jedi.
It already has TWRP on it, but recovery is inaccessible since I turned the OEM lock back on. The only thing I can now access is download mode but it can't seem to write to it, which I'm guessing is because the OEM lock is back on. I thought I might still be able to write the official Samsung ROMs even with the OEM lock but it doesnt seem like its the case. Obviously no access to ADB to do a Fastboot unlock either. Fresh out of ideas.
Any other solutions?

bump - anyone? lol, really not looking for an expensive door stop.

It seems you're at the dead end. However, there might be a solution for this, not sure though does it work. But go to OnePlus forum and you'll find how to recover from bricked device. You still got hope because of TWRP. good luck bro

OK, so for anyone wondering if this is fixable, the answer is YES!
You can flash the standard ROM even with the bootloader locked. Clearly what I downloaded from SAMMobile wasnt compatible, however when I used Frija, it found and downloaded the correct ROMs.
Another sticking point of this was the infamous USB 2.0 issue, I assumed the ROM was failing again, however when I finally could be arsed to try it on my old PC, its worked like a charm.
So there you have it:
Latest version of Odin
Latest Samsung USB drivers
Latest ROM downloaded from Frija
Put the tablet into download mode and flash away.
