[Q] assistance downgrading removing bootloader - Galaxy Tab 3 Q&A, Help & Troubleshooting

So i updated my sm-t210r (worst decision ever) and instantly began noticing bugs one of which is my apps stopping at random even system ui and touchwiz home. I used the latest philz touch recovery did a clean wipe and flashed nolekat`s rom and the same thing happen apps keep stopping, so i did a test i flashed the same rom in the same exact way on my sister`s tab (not updated) and what a surprise everything works great on hers, no random stops, great battery life, even the screen and graphics are more whiter than mine, so i concluded that its this 4.4.2 updated that is causing all the problems. So what i ask of anyone is steps to completely downgrade romoving the new bootloader in the process, i already tried flashin the old 4.1.2 through odin but all the issues remain, any help or tips would be apreciated

help guys no matter how tedious the process i really want to downgrade and remove this bootloader

[Q] MIUI ROMs - Problem with touchscreen randomly becoming unresponsive and rebooting

Hi All,
Been having a problem with the touchscreen randomly becoming unresponsive or the phone rebooting on its own ever since when I'm (trying) to run MIUI ROMs.
By "random" I mean that it sometimes occurs while typing, switching home screens, opening an app, or even just when the phone's idle.
Not experiencing any unexpected FCs throughout the MIUI ROMs that I've tried however... so at least that's a good thing?
I don't experience any of these problems at all when running a stock Sense ROM, so I'm hoping it's not the same rebooting problem described in another thread that requires sending it in for repairs as that would be very troublesome.
The phone's a HKCSL Desire that was rooted using unRevoked. The problems occur even when I don't install any apps onto the phone and when the phone's just idle with the screen off (for randomly rebooting).
Any suggestions would be greatly appreciated =) and I hope I'm not just SOL for MIUI ROMs since no one else seems to really be having these problems.

List of things I've tried:
1. Full wipe with Dalvik & cache before flashing a ROM (many, many times)
2. Updating to 32.48.00.32U_5.11.05.14 radio and downgrading to the suggested 32.44.00.32U_5.09.05.30_2 (Thought it might've been caused by WiFi connection as I always have it on... but doesn't seem like it)
3. Using different versions of Clockworkmod (2.5.0.7, 2.5.0.1, 2.5.0.1 modified by MIUI.cn)
4. Repartitioning/formatting SDCard before/after flashing a new ROM
5. RUU-ing the phone and redoing everything from scratch
6. Using an untranslated base MIUI-Desire ROM
7. "Upgrading" the ROM by flashing on top of the 10.15 build
Versions of MIUI ROMs I've tried:
Pretty much all the releases of 10.15 and 10.22. Currently fiddling around with eevek's stock 10.29 and mobiousdigital et al.'s 10.29 builds.
Hopeful bump =)

[Q] Problem with 4.4.2 and MJ5

Hello guys,
I have some issues while using the latest 4.4.2 DN3 ROMs. Before installing DN3 4.2 I flashed MJ5 bootloader, and it was running for a couple of weeks fine, then the phone started to freeze and reboot several times a day. I thought DN3 v5+ would fix these freezes and reboots but it was no good. I was really disappointed, as I really liked the look and feel of DN3. Now I'm using Revolution HD 31, it's stable (more or less, a couple of freezes and reboots for two weeks) and fast, but I really liked the looks of the latest DN3...
So the question is - what can I do to avoid these freezes and reboots and will upgrading the bootloader to a newer one will help me?
I don't think bootloader has anything to do with it. I was on MJ5 with 4.3 creikelo and NEVER had a reboot or force close. DN3 just freezes after 1-3 days. I had the same experience. It started getting laggy, or better said, the CPU was doing something, hence the lag, and then it just restarted by itself. And I did clean install. It is enough to reat the DN3 topic and see how many people have problems with it - and most still consider it the best ROM... I just went away to another ROM, and will post results in a week hope it doesn't behave the same as DN3
Thanks for the reply!
What ROM did you install? Is it stable?
I had a problem with mj5, my phone froze on the boot and i had to reinstall the ROM.
I think mj5 is for 4.4.2 ROMs, is a older bootloader.

I tried JellyKat 6.7, but seems I have same issue... at first it was getting high CPU usage after a day or two, then phone became so overloaded it reacted to nothing and I had to pull battery out. Then all of a sudden I started getting SOFT reboots (that means only from the point of boot animation, no samsung screen) and I installed Xposed module Samsung Crash Fix and will see if it helps... I dunno, I am begining to believe there's something wrong with all 4.4.2 ROMs Because I never ever had FC, crash or reboot with 4.3 Criskelo....

[Q] S4 mini rebooting very often!

Hi all!
First of all thanks for your work..it's awesome!!thanks to you i enjoyed my s plus until some days ago it has broken..very sad day
However i decided to move on with a more modern cel, so i decided for a s4 mini.
But since the beginning i've had lot of problems..
My phone after an original update from samsung started to freeze and reboot..more and more often..i read it could be an issue with original update so i decided to mod my phone since i've had great improvements with my old s plus..
first i installed cm11 but the phone keep rebooting and rebooting ..so i installed cm12 with android l..but the problem is still here!!
the more my phone became hot the more it reboot..it's unusable and i don't know what to do..i'm also begin to doubt it's a hw problem
my warranty is gone with all this mods..so what to do? any others has this kind of problem?
thanks if yo want to answer
People encountering this should perform a factory reset and wipe everything from the phone.
Then, perform a clean install of whichever rom you wish to use, without any additional apps.
I recently encountered an issue with Apex Launcher and a recent update. Android keep crashing and soft rebooting often.. only after a few days did I realise the launcher was the issue. Since I uninstalled the app the phone hasnt restarted once!
Mine restarts after i turn on Mobile Data + GPS for navigation..
It works for a minute and restarts.
I don't know where the problem is either. I tried to flash cm10, 11.. stock 4.2 / 4.4 and nothing seems to get me rid of the problem

Random restarts while on Stock Lollipop

I haven't rooted or made any kinds of major adjustments but still there will be times when it will randoms just restart for reason I'm unaware of. What can I do to track down the reasons for the restart?
On a side note: really considering rooting since it doesn't seem like this tablet is going to get marshmallow. What roms are out there that have good support and still allow me to use the S-Pen?
I don't know how to track down but how about flashing stock 5.1 rom with odin?
Maybe it can solve the problem

T800: Can't complete boot when using 7.x.x roms

I had the latest 6.0.1 samsung rom (CPK2) which was giving me problems with freezing. So I am trying to upgrade to an 7.x.x rom, either RR, AIPC, or Lineage. But none of these roms allow the T800 boot to get beyond the initial splash logo screen. I am using latest TWRP, 3.1.1 to wipe and install rom. I am not getting any install errors. Boot loader is confirmed as CPK2.
FYI, I am able to get back to the samsung rom by reflashing it with Odin.
Update 1: In the final attempt of upgrading I installed the official 6.0.1 fw which boots fine unlike the aforementioned alternatives (very strange). However, lock ups and now screen blanking more frequent. This time wiped everything including storage. It looks more like a hardware issue but I wonder if this could be malware even after wiping everything. I will have to take this in for repair but have little hope of solving this problem.

My wife has the US Cellular 10.5 variant (T807R4). It was freezing so frequently it had become almost unusable for anything but watching videos. Rooting and disabling most of the Samsung apps did not fix the problem. I wiped the system with TWRP only to discover that none of the custom ROMs would work on this model. I downloaded and flashed the stock Samsung MM firmware (and it sat on the opening splash screen for at least 15 minutes before it finally booted up) and for the hour I used it after setting it up, I had no problems. I had previously cleared the cache with Titanium Backup and that also seemed to be a temporary fix. My conclusion is that something is happening when the cache fills up that causes the freezes but I'll need more data to say that for sure.
Just an update: I was going to have the hardware looked at so I wiped everything including the storage. But when I took it to the shop and was asked to demonstrate the freezing the tablet wouldn't. So I took it back and it was running OK until a couple weeks later when the same problems reared there heads.
Somehow I managed to get a 7.1.2 installed and the T800 is running great...so far. I'll post back if the freezing starts again.

Please explain the steps to install 7.1.2 (and which ROM you used) and update on the freezing issue. Most of the freezing issues I have read about seem to be on LTE variants (SM-T807x) so I was about to buy a wifi only (T800) tablet, thinking that would be a solution to the problem. If that's not the case, then I shouldn't waste my money.
The instructions for installing a non-stock ROM are on the dev's host page in Tab s forums. I first tried Resurrection Remix and now am on LineageOS. It was only after I wiped the internal storage area that I was able to get past the 7.x.x boot screens.
I found the stock rom 6.0.1 freezing issue persistent. I believe the problems started for me with XAR H4 and really picked up with K2 (roms supplied by sammobile). The tablet would frequently just freeze while working in an app: the screen and hardware buttons would not respond at all. Never had that problem with Android 5. The only thing I was able to do to unfreeze it was to reboot into download mode then restart the OS from there. I sometimes found that if I left it frozen overnight it would unfreeze itself by morning.
