[Q] Help! I tried to root my tablet and now I seem to have broken it -- it won't boot - General Questions and Answers

Alright, so yesterday I tried to root my tablet (Samsung Galaxy Tab 3 10.1 Wifi) yesterday by installing TWRP and then loading the Superuser zip found in their link in the play store. It worked fine--I had root access and all was going fairly well. I then tried to make a small tweak to the build.prop file by changing ro.build.version.codename from REL to L.
When I rebooted to apply that change, I could not start up, so I did a factory reset (not a big deal, no essential files on there). It then booted fine, but when I reinstalled/updated all my apps, the Google services were crashing like mad. So I reverted the build.prop file back to REL and again it would reboot, so I did another factory reset and all was good; the Google apps were fine.
Well I was still rooted and I wanted to take advantage of all that time I spent doing it, so I downloaded the bootanimation zip found on this thread and replaced my bootanimation.zip that was already on there. I restarted to see the animation, and this is when the real nightmare started happening. I could not boot now at all.
I did another factory reset, and still it wouldn't boot. I then used TWRP to do a full reset, and still nothing. I did an advanced reset and somehow managed to delete the operating system files (I have no idea how), causing TWRP to say that no operating system was installed. I still couldn't boot, of course.
Finally, I decided I had had enough of this rooting ****. I searched all over the internet looking for a North American version of my stock ROM, and finally found one posted on this forum post. I wouldn't normally trust any random file, but I was getting desperate here. I used Odin to flash that ROM, and there were no errors. Now when I go into recovery, it gives me stock and not TWRP, so I know that was probably successful.
However, I still cannot boot. I get stuck on the screen that says Samsung Galaxy Tab 3, which sometimes goes away and then comes back. I can't send it in for warranty, because it still says "custom" in the recovery mode. How can I fix this? any ideas?
I really want my tablet back :crying:

Stuck in a loop, need help

Hi all
I’m a complete noob at this and it seems like I have got myself into a bit of a pickle. Sorry for the massive description but I thought it would make it easier to get a good answer.
My Phone:
Samsung Galaxy S4 GT 19505 LTE
PDA I9505XXUEMK8
CSC I9505BTUEMK5
MODEM I9505XXUEMK8
I successfully rooted my phone using Odin. In Odin I added the "CF-Auto-Root-jflte-jfltexx-gti9505.tar.md5" file to the PDA field then rebooted the device. Then I added the "openrecovery-twrp-2.6.3.1-jfltexx" file to the PDA field, rebooted the device and the phone automatically opened in TWRP recovery. In recovery mode I wiped the cache, system and dalvik cache. I then went to install, browsed to the "I9505 Official_Google_Edition_4.3_by_Jamal2367_Finaly_v2.0" file on my SD card, rebooted the device and the Google logo came up on the screen for a few minutes and all was good. Got my new ROM, ran a root checker and all was good.
After some research I decided I wanted to use the Pacman ROM as it seemed to a lot more customisable. Using the same method I went to TWRP recovery wiped the cache, system, and dalvik cache. I then went to Install, browsed for the pacman ROM and the Gapps file on my SD card and everything installed ok, the phone restarted and the pacman logo came up everything was fine. Although I did notice on start up that I got this message.(and have had this error message ever since)
kernel is not seandriod enforcing
set warranty bit : kernel
After using the Pacman ROM for a day I noticed a lot of bugs like my apps would disappear, I couldn't use my banking apps and my phone was generally performing very badly. So I decided to remove the ROM and use CyanogenMod ROM under the recommendation of a friend. So again I pressed home+power+vol up to enter recovery mode but this time it didn’t enter the TWRP recovery it entered the stock recovery mode. This was slightly concerning but I proceeded to use the list menu and cleared the cache etc, browsed the SD card and went to the CyanogenMod 10.2 ROM I previously downloaded. It began to install but in red I got the error message stating that I didn’t have the right permission or signature. The phone rebooted back to the Pacman ROM. I tried the above three times and it still continued to boot back into Pacman ROM sometimes I struggled to even get back into recovery mode.
Soooooo I decided to try and go back to the Google Edition 4.3 ROM and play it safe, using the method from my first paragraph. But when it installed through TWRP I got an error message saying cant find MD5 file. The device rebooted and the Google edition logo came up on the screen but it seems to be locked in a loop. The Google logo wont go away and the phone vibrates once then three times quickly every 10 seconds.
I can still enter both TWRP recover and Download Mode. But I don’t want to mess around with it anymore without getting some advice. Any help would be much appreciated as I really need my phone working.
Thanks again
Aiden
Did you create a backup while on your first run with google edition? If so wipe cache, system, and dalvik and restore to your backup. Should put you back to where you began.

I know I should, but I didnt. Is it still fixable ?
*Update*
Couldnt help myself had to have a tinker around. Managed to get Cyanogenmod 10 working with Gapps. Gonna see how I get on with this. Although still would like to know I have been having all these problems.
Sometimes things just dont go as planned: p I have easily soft bricked my phone around 10 times and always able to fix it. You really should have made a stock backup before flashing anything. I recommend doing it now so you at least have a known working configuation backed up for future use. Trust me backups are your friends!

Thanks for your replies.
Ye gonna that right now Cyan Mod so far is running very smooth without any problems.

[Completed] System UI has stopped--Stock OS

Earlier today, I got an error upon starting up my Samsung Galaxy S5 (T-Mobile) that says "Unfortunately, System UI has stopped." My background has been turned to black and none of the buttons work properly. The phone IS rooted (and has been for about a week), but runs on stock OS (5.0 Lollipop) and stock recovery. I have never flashed a rom on this phone. I already tried restoring from a Titanium Backup I made yesterday before this error ever showed up, but it did nothing. Perhaps it's relevant that this error first happened after I booted the phone in recovery mode (to see what stock recovery looked like), then selected "reboot phone." I also already tried wiping the cache partition, wiping the System UI cache, and rebooting is Safe Mode. None of these worked. I thought unrooting the phone might help, but I accidentally uninstalled SuperSU without removing the root. With the System UI down, I can't install any apps at all, such as SuperSU again or a file explorer that would allow me to remove the "su" folder in /system/bin/. Now I have no way of unrooting, short of wiping the phone. I DO NOT want to do that. How do I get my phone back to normal?
--EDIT-- I finally gave in and did the factory reset. I rooted it again using the same method as before (in order to use Titanium Backup), and just to see what would happen I went to recovery mode. Sure enough, I was greeted with the same error as before. I had already rebooted the phone normally multiple times before trying to use recovery mode, so I have no doubt that the stock recovery mode is the cause of these issues.

Personally, I don't like Titanium Backup. I seem to be in the minority with that opinion, but it's given me issues in the past. Try flashing a non-stock recovery like TWRP for your S5 and either wiping your phone or wiping and flashing another ROM.
Samsung phones seem to dislike rooted users for some reason

Too late, I already wiped the phone. I re-rooted using Chainfire's auto-root, then flashed CWM so that stock recovery doesn't screw me over again. Before restoring from the backup, I booted into CWM recovery and restarted the phone. No error. I hope it stays that way, this whole thing is a huge hassle. There really needs to be a disclaimer with Chainfire's auto-root telling people to get rid of stock recovery!

Galaxy A5 A500F- Stuck In TWRP

[Q] Stuck on TWRP/System Recovery. Need help.
Hello, first time posting here.
So like the title says, my phone is stuck on System Recovery. I have a Samsung Galaxy A5 (A500F model), rooted, and with TWRP installed.
The phone was running fine for 3 months without problems, so I guess it must be from recent installs, but I haven't installed anything since last week. The last action I did prior to this problem was going to System Recovery via Link2SD app, since the usual button combination didn't work. So I guess the fault lies there? At this point I have tried everything I can do, like restarting, rebooting, wiping, factory resetting, and I even restored a backup but it still goes to System Recovery after every restart.
This is my first problem on Android phones, so I hope you can help me.
If you need more information, I'd gladly provide.
Cheers.

Cant flash Cyanogen, recovery faulty & weird crashes in stock on refurbished Nexus 5

Cant flash Cyanogen, recovery faulty & weird crashes in stock on refurbished Nexus 5
Hey guys,
so I recently got a "refurbished" replacement for my Nexus 5 and I decided since im starting out fresh (can't access the data on the old one), I'll try out Cyanogen mod.
I can assure you that I followed all the instructions exactly. At some point I checked every download for his checksums and all were ok.
Each time I started the process by flashing a factory image (flash-all.bat), to have a clean start.
I also tried to wipe cache/dalvik cache/data afterwards, but not always. This didn't change the behavior.
These things happened to me while trying to accomplish the task, and working around the issues as they arised:
Flashing TWRP: High (3 of 4) chance that TWRP wouldn't even start up, the phone would hang and just flash the TWRP background picture on screen.
When I did get through to TWRP, applying the Cyanogenmod .zip got stuck at "patching system image unconditionally". Let it go on for hours.
I figured that TWRP was broken and tried Clockworkmod instead. CWM at least always started after flashing it. But same as TWRP, it failed in installing the Cyanogenmod .zip. I tried putting it onto the phone by going into the stock android and then through adb push command, but also through sideloading directly into CWM.
What I noticed when going into the stock ROM was, that a lot of Google processes were failing during the initial setup (where it wants to know ur WiFi, date, Google acc, etc), like Maps, Settings, Play Services, and some others. Sometimes they were failing so hard it was impossible to type in the WiFi passphrase because the notifications of different "xxx has stopped working" were coming to fast, sometimes not a single one was failing. I could not find any pattern to this. When they were failing so hard I couldn't get through the initial setup I would just flash the stock again, until I got only some of them failing, or none at all.
Back to CWM and installing the Cyanogenmod .zip:
It failed with different errors. I got status 0, status 1, I think I once got status 6 or 7, but half of the time it hanged exactly where TWRP was hanging. The errors were random. After getting status X, I would sideload it right again, to get other status Y, sideload again, to get the hang. Could not recognize a pattern.
During this I switched USB ports, and cables, and even tried using my laptop instead of the desktop. One of the cables was faulty, it didn't even allow a connection, but any other setup showed the same behaviour.
Is there anything else I can/should try? Is it my fault, or is the phone bad?
Assuming the phone is bad, I suppose I still could get a stock running without the crashes, so it would _feel_ like the phone is alright (which is what Google probably did before sending it out again as "refurbished"), but I think there would be errors in the future, also I don't want a phone with such an uncertainty. Would they swap it? Also, it is a LG-D820, which means it might have issues with european LTE, haven't gotten to trying that out since I don't use LTE right now, nor will I in the near future.
Best regards,
napster

Hi.
According to what you say, it seems an hardware problem of you phone. Don't know if it may help but you can try installing an older factory image (for example kitkat) and seeing if the "force closing" problems are still there. If your phone is ok it should be able to run a factory image at least.
Download the nexus root toolkit, create a nandroid backup, then when either in CWM or TWRP wipe everything off the phone then try to flash a ASOP rom like Cataclysm if nothing else works then I don't know how to help sorry-.-
So I tried to get the stock ROM up and running again, and it seems even that is not possible. Several processes keep crashing during various tasks, even when idling. After having a short chat with Google Support about the issues I got an RMA offered, so things are cool. I locked the phone again, set the tamper-bit to false and wiped everything.

S7 G930FD TWRP Bootloop - please help

Objective: I am hoping to be able to boot my existing system to recover data such as SMS, call logs, app data, and so on - obviously it was inadvisable to start messing around without backing up my data, particular with my amateurish capabilities. But that's the situation I am in. For some reason I thought that just replacing the Recovery was not going to risk my data. Its been over 5 years since the days when I would regularly flash my new phones with cyanogenmod, and my abilities were very basic even then.
Context: G930FD with stock rom, baseband ETC? - apparently for Dubai, which does not allow VoLTE or WiFi calling, which is what I was trying to fix when I got myself into this.
the Events:
- I enabled ADB and used Heimdall on Windows 7 to flash twrp-3.3.1-0-herolte.img
- initial attempts failed to complete download. I booted back into the system and applied OEM Unlock. Flashed successfully.
- chose the 'allow modification' option or whatever it says, not the Read-only option
- I did NOT check at that point to see if the system would reboot properly. I instead right away made a full back-up to my external SD.
That's all I did. After the back-up was complete I rebooted, and arrived at "SAMSUNG Galaxy S7" endless boot loop.
best guess: this is related to samsung encryption? TWRP file manager says that DATA is 0MB.
Again, I am desperately hoping that someone can help me recover my existing system. The threads I found on this subject all lead to wiping the phone and flashing a new rom.
thanks.
digging in deepr
I went ahead and rooted by loading SuperSU otg through TWRP.
Now I get passed the first splash screen that was previously boot looping (Galaxy S7, powered by Android), and I get to the 2nd splash screen (glowing SAMSUNG logo). It does not boot loop, just glows in and out endlessly and never loads.
Is that progress? Or maybe its worse.

Reflash TWRP with Odin, boot TWRP, wipe cache, reboot.
Thanks.
I think greenman at sammobile had the answer --> NEW: S7 5 file firmware options (this forum wont let me post a link).
But I botched the execution and the CSC file overwrote my data. Crushing blow. I would say lesson learned, except that I already knew better and risked my data anyway. Sad.
I have a backup I made at the first launch of TWRP - but I assume its worthless since TWRP was not reading the encryption. Its only 3.7GB.
Side note - I did achieve the original goal of replacing the Emirati rom with one that activates WiFi calling and VoLTE.
Has this issue been solved?
I never recovered my data if that's what you mean. Did you look up greenman at sammobile? It sounds like someone followed his directions and was able to flash just the system files without overwriting their data. I think you had to modify the csc_home file. It was a bit beyond my skill level.
Oh, I was just wondering if your phone was still bricked. I didn't read your last message properly before replying lol. My bad.
I'm not personally having issues with a device, I was just curious if I could help at all.
