Does anyone know how to fix the crashed phone app. I search the entire forum and haven't seen any achievements. I'm using s8 plus att.

P/s: i tried freeze the voicemail but it came up with the error: android.phone ... something like that
[Samsung Galaxy S8+ ROMs, Kernels, Recoveries, & Ot] braswellington:
Yes

Delete the visual voicemail app from system app folder, used sd maid pro to do it. Reboot phone and it should work. Freezing it did not work for me either

I never used SD Maid Pro before, i just switch to Android from iPhone. And i just bought SD Maid Pro as well. Can you show me how to delete the visual voicemail please?

[Samsung Galaxy S8+ ROMs, Kernels, Recoveries, & Ot] hazmad:
I'm no expert, but I think upload mode is triggered by a Kernel panic, which happens when you have a problem with your firmware, hardware, etc.

Your system probably crashed, for whatever reason.

you can try:

- Disabling bad apps (task manager?) or revert setting(s)

- Deleting your cache (recovery)

- Factory reset

- Wipe and reinstall firmware

Potential warning for those wanting to install sprint's newest AQH3. If you use supersu.zip provided by one user it shows tmobile stuff in system settings but beyond that it also has a popup that you must click ok to which says "service provider update" and that a new carrier was detected. You hit ok and it reboots. However it continues to pop up every reboot and you cannot use the phone. If you take sim out you can disable that app but they you get force closes and no data still. I reflashed using the QG2_ADD_CSC_SYSTEMROOT.zip file in the OP and all is well there. It does seem they may have removed calling plus from AQH3 so I'm probably going back to QGL. Will report back once I make heads or tails out of what is exactly going on but honestly for sprint I'd steer clear of that supersu.zip for now. Even though build reports and older version all the latest FW stuff works (Calling plus, etc) so I wouldn't worry about that so much.

[Samsung Galaxy S8+ ROMs, Kernels, Recoveries, & Ot] IJoxer:
This root method does, but each firmware will be slightly different, mainly for optimization with the carrier/software/network. Apparently it was released today for Verizon, so we should be good to go, but something to keep in mind in the future.

Yes, you should be able to do this, though you will have to run the wipe option in Flashfire in order for everything to go smoothly.

[Samsung Galaxy S8+ ROMs, Kernels, Recoveries, & Ot] AndroiderM:
I was running XAA on my AT&T S8+ before root if that makes a difference. Should I flash the ATT CSC instead of Home CSC from XAA. before root I installed the full XAA firm with home CSC and had no issues.

Will SU stick or do I need to flash a zip with img and csc
[Samsung Galaxy S8+ ROMs, Kernels, Recoveries, & Ot] TT_Vert:
CSC -> there's a PIT inside and will wipe your device

HOME_CSC -> the data should stay on your device

Reboot phone to upload mode press power + volume up + volume down until screened goes black after about 20 seconds upload mode will start

Leave on this screen another 20 to 30 min

To get out of upload mode press and hold the power + volume up + volume down until you see s8 screen

You will have 100 percent battery the hillbilly way.

I've confirmed the "hillbilly" method works

if your blue led isn't on, it's not charging.

- reboot

- wait until after the initial boot screen starts up

- then hold down all buttons until it goes to black screen (release)

- wait 20-30 seconds, it'll go into upload mode

- charge away

- hold power + vol down to reboot when done

He was referring to flashing the QGL update, which at the time, was only (technically) available for att and sprint.

???

I was making a clarification, not declaring any doubt as to whether or not I could do it. I've been rooted using this method since release on VZW 8+, no issues, other than constant echo of people cluttering the thread with what they'd have known by searching the thread and even a vast number who simply failed to read the OP.

I don't mean to direct that last bit towards you, it was a long day at work, and this thread has literally been the worst I've seen in terms of people not searching/reading before posting. I mean, stop asking to be spoon fed people, if you're willing to attempt technical procedures that could possibly brick your $800 device, I would think you'd take a more proactive approach in being successful.

Flash the XAA firmware then use adb to set carrier specific options and features. That's what I did and have attached boot and sound, WiFi tethering works even though it's supposed to be blocked on my plan, volte, wifi calling is activated but I haven't tried it yet, no ATT bloat apps were installed and my build number is U1 still[emoji106]

Adb shell or SU command works for this once in adb. You can also use a emulator and do this right on your device if you'd like to go that route.

echo "ATT" > /efs/imei/mps_code.dat

Hit enter

Then type

Reboot

Hit Enter, phone will reboot

This should work for all carriers, you just need to know your 3 letter carrier id, those can be found in the carrier switching threads.
[Samsung Galaxy S8+ ROMs, Kernels, Recoveries, & Ot] the1stSecond:
Same here; worked:

-I charged to 80 and then went to upload mode.

-After letting it charge in upload mode for about 30ish minutes I rebooted and, for the first time since root, saw 84% on display.

So, I thought to myself, ill do that again and see if I get 85% for grins.

-Back to upoad mode, another 30 minutes of charging, reboot and boom 85 displayed. I thought, OK, this must be the leakage verbiage I saw in the JSON files. But, ill see if she goes to 86. -Same routine, but no dice, still 85. So, I began keeping loose track.

From this point:

-The displayed % dropped very quickly from 85 to 81 (within 4 minutes) of just doing, well, nothing really. Just flipping through files in Root Explorer, deleting junk etc.

-It then sat at 81 for a few minutes then touched 80 for several more minutes THEN went back up to 81.

-Sat at 81 for longer than I have EVER seen the phone stay at any % displayed (i suspect this is when the battery started draining from 100...).

-Once it finally did hit 80, this time, it began draining as normal.

So, it definitely worked, just wonky in displayed %.

I'll conclude in the time I've written this message, walked the dog, explained a scene of Mr. Robot to my wife and came back to finish this post, my displayed % remains 81. Normally, it would easily have hit 80 by now.

I don't know what the hell is going on. This is nuts!

Edit...even after correcting my grammar in post three times, it's still at 81.

So I tried to flash the latest XAA IMG and CSC with flashfire starting at step 2 and got the sim settings update reboot pop-up over and over. I got back into download mode and used Odin to flash the new firmware to get back to stock XAA. I would like to start the root process over using the newest XAA IMG and CSC in place of the included files in OP.

When trying to start from step 2 I added both the IMG and CSC as OTA updates in flashfire since the CSC wasn't in zip format. I'm not sure if this is what caused the problem.

Can someone please host the IMG and CSC from the August XAA build in the format needed to achieve this. I am battling a slow DSL connection and an ancient Gateway laptop capable of Odin and ADB barely lol. I generally download firm with my phone then OTG to flash drive to use with the crypt keeper laptop.

I can't seem to extract the IMG from AP with my phone . I can use solid explorer to navigate to it but cannot copy it to internal storage. Also if the CSC needs to be zipped for installation to work do I just use an archiver to zip it or is there more to it?

If someone could provide some instructions or host the files needed I would greatly appreciate it.
