[Q] Verizon S6 keeps Rebooting - Verizon Samsung Galaxy S6

I'm not sure what's going on with my phone (Samsung Galaxy S6 from Verizon). I did install PingPong root and was enjoying it until yesterday morning when the phone was stuck in some weird boot loop.
After getting root, the only thing I've really done was to try to get into servicemode app by modifying the file
/efs/carrier/HiddenMenu
Modifying this file worked and I could access the servicemode app fine.
I've gone through a number of different steps to try to get it back to a normal operation but nothing has worked:
1. Factory reset
2. Cache reset
3. Odin + original firmware found on this forum
4. Verizon tool to repair phone
In every case, the phone will boot, load Android and show the initial setup screens and then after 1-3 minutes it will restart. There is no warning, it just reboots.
I've tried to look at logcat or dmesg to see if there is anything suspicious but it doesn't reveal anything.
The only clue I have that the above steps haven't completely reset the phone to the completely original settings is I am still able to access the servicemode app. I cannot under the HiddenMenu change I did without rerooting the phone.
Does anyone have any idea what's going on with my phone? Are there any logs or places I can check for actual issues?
Any help or advice is appreciated.

Rogers Samsung Galaxy S2X (SGH-I727R) Root Failed!

I have a samsung galaxy s2x (SGH-I727R) from rogers. I tried to root it but it did not work as I used a wrong instruction (http://forum.xda-developers.com/showthread.php?t=1514434) Then I did reset factory which removed the USB storage and made the phone fresh. I then tried another instruction that I cannot remember what it was. I did not work neither I guess. Because, when I put a Bell sim card into the phone it did not recognize that, but there was a superuser app installed in the application menu. However, I tried to run the reset factory again and try another approach, but it did not work. When I try to run reset factory it stops after a couple of seconds. When I shutdown the phone, it cannot completely be off and I have to remove the battery to make it off. I also tried to enter to recovery mode but after pressing a button in that mode the phone is crashed and I need to restart the phone.
So I am really really confused and I don't know what to do. I am also new in this kind of things. Any help would be appreciated.
Thanks,
Ebi
restore to stock, install cwm or twrp then root, howto's in my sig

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

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:

My samsung j2 prime (sm-g532g/ds) will no longer turn on

Good afternoon or whatever time you have there, greetings. So here's the situation: I've been trying to root my Samsung J2 Prime, about two days ago, using KingRoot, KingoRoot, and FramaRoot, but to no avail, they did not work. So, becoming desperate, I ventured to the dangerous thing I regret doing: flashing its firmware. So I've attempted to root it with Odin, and then it said "To start up your device, enter your password." And I was dazed, I don't have a password! And if it really had a password before, I don't know! Moving on, I've not attempted to wipe its data, knowing the files in it. So, I tried to recover it on Odin by opening download mode, the FRP Lock is on, so unfortunately most of my ventures are unsuccessful. Then, after entering an incorrect password (on the home screen something of the "To start up your device..." screen), it proceeded to wipe factory data, which then prompted my phone to have a bootloop, however I could still access download mode, but not recovery mode. Then, when I've somehow managed to access recovery mode through root boot on Odin, I've wiped my factory data and the cache partition. Then, after a few attempts, I used some firmware I've downloaded and it said it worked for me so I was at first. But when I checked my phone, it would no longer turn on! As in it wouldn't boot at all, even remotely. The charging screen won't even appear. I'm going crazy. I've tried to remove the battery then return it, to no avail it won't work. I really don't think it's a battery issue. Can anyone help?
(Btw, I've been following random YouTube videos whose links I've not saved, and some random pages. Also, I'm not sure with my carrier, but I'm more confident that it's Globe.)
Are you install stock rom to your device through odin?

[HELP] My J3 Emerge from Boost Mobile keeps turning on and off...

I tried several methods before.
First was flashing the modem to work with GSM cards on calls and messages, but no data. I tried getting the MSL somehow but that didn't work. I flashed next TWRP without knowing anything about wiping the cache after installing SuperSU. I had to download the stock firmware again, and it was working stable until it shut down again when I flashed the new modem. I'm not sure what's causing the problem.
Keep in mind that I have two J3 Emerges, the one I'm modding and another one that has a cracked screen which functions very well. And I don't wanna mod the second J3 because of reasons.
EDIT: I just found out that formatting data via TWRP just causes the phone to behave normally, until somehow its connected to something... USB wasnt connected, and I think it has to be because of the phone checking the status of itself, despite being 'custom'.
EDIT 2: Found out, that the phone goes on a boot loop whenever I connect to the internet. Obviously, something must be going on.
EDIT 3: Looks like configuring the network was the issue... DANG. Anyone know of a way to bypass this bootloop?

Galaxy S7 G930U Unlocked stuck in boot loop - already flashed successfully but no fix

I'm really hoping you guys can help me out here. This is an S7 I bought from a Best Buy when I visited the US in 2017, and I got the Unlocked version so I would be able to use it back in my home country. Unfortunately, this is the second time I've had trouble with it in a span of 4 months and the first time it was a hardware problem and ended up quite expensive to get fixed.
Today I was using my phone normally when I decided to use the Google instant translation to translate something on my computer screen. That caused my phone to freeze, restart, and then tell me I was using an unauthorized flash and it was going to be locked, or something like that. Even after restarting a few more times, the phone would never get past that screen. I proceeded to factory reset/cache reset and from then on the phone just got stuck in a boot loop.
I learned that the fix would be to flash the phone. After a lot of work I found the G930UUESACSI1-20190930144640 firmware (the XAA version, for Unlocked) and successfully used Odin 3.13 at the Download Mode screen to flash my phone. It then restarted, went back to the blue screen, started installing some updates, when it was 100% it restarted again. Unfortunately, the loop remained. Galaxy S7 logo first, then the Samsung logo, then it just repeats.
I have also tried turning the phone off with the Recovery screen shut down option (since I can't seem to be able to turn it off with the power button right now), wait a few minutes, then turn it back on. Nothing changed.
Please, does anyone have any insight into this? What else could I possibly try, or what could I be doing wrong? I really don't want to send it to repair yet again in such a short time.
Many thanks in advance.

You need to clear the cache after flashing to get out of the boot loop.
Use the download key combo to restart. As soon as the screen goes black move to Volume up+home+power.
In the recovery menu choose clear/ Wipe cache, then choose reboot.
I apologize for not updating this thread before when it was still recent. The fact is that I didn't manage to fix my phone; clearing the cache after flashing did nothing to stop the loop.
I ended up taking the phone to the people who have fixed it in the past and after more than one month, they gave up. So I got my phone back and I want to try to give it another go before I just sell it for parts.
Unfortunately, my phone has come back even worse. Now it has no Recovery Menu to speak of, at least none that I can access; after a few seconds of the blue text on the top saying that it's entering recovery mode, it then proceeds to a blue screen saying: "Security Error: This phone has been flashed with unauthorized software and is locked.". I can still access Download Mode.
I have attempted flashing a few firmwares that I believe should have worked with my SM-G930U. Odin listed the attempts as "pass" and, after restarting and going back to the Download screen, it says the binary is Official. However, after trying to restart the phone normally, it starts displaying the blue screen again, and then, after going to Download mode, the binary is reverted to "Custom".
I believe right now the order of the day is to get the recovery menu to work again so I can do all the cache cleaning that seems to be required after flashing firmware. Any ideas at all on how I should proceed? Is there something specific I should download to fix the recovery menu?
How many files are you flashing in Odin, is it just 1 file in the AP slot, or 4 files: AP, BL, etc.? Also, is your phone rooted?

Never rooted, was using the phone legit before it froze and entered boot loop. I flashed all 4 files, multiple times.
Someone tried fixing my phone a few days after I replied to this thread and some progress seems to have been made, but now the phone cannot get past a black screen with a "SBL Error! rdx_init!" in red text, and "upload mode" in yellow text. Still cannot access Recovery Mode, but Download Mode still works.
I did a little Googling on rdx_init errors and it seems I need a firmware dump from another G930U or something like that...any ideas on how I can proceed?
Flash it with Eng Boot in all slots using patched Odin. Reboot to recovery and wipe it. Reboot system. Then root it with advanced adb root. Links for all of this are here in xda. Enjoy

Sorry, I'm not an expert at this by any means, I'm not sure what files to get. So far I've found and downloaded the following:
S7_Oreo_Nougat_Adb_Advanced_Root_V10
S7_Oreo_Nougat_Adb_Advanced_Root_V12
S7_Oreo_Su_Binary_Only_ADB_Root
But I had no luck flashing any of these cause my binary is 10. Is there any more help you can provide me? I really don't know how to proceed

I thought I had one in my phone, but I don't. If you look at the thread where you downloaded the Root_V12, you will see it. It's near the end of the thread somewhere.
