[Galaxy S 5 Q&A, Help & Troubleshooting] ShalaMala:
Hello.

This is my first post as I've done everything myself till now, but now I'm really lost in some uncharted territory.

All I wanted is to have a second DeGoogled phone and I messed my Samsung Galaxy S5 beyond my understanding :eek:

So, I flashed TWRP to my SM-G900F klte through Odin and then installed /e/ ROM through zip method and everything was working fine, then I wanted to flash Intelli kernel, but I got an error saying "Digest failed to match on '/external-sd/Intelli-Kernel-v15-klte.zip'. E: Aborting zip install: Digest verification failed. Error installing zip file '/external_sd/Intelli-Kernel-v15-klte.zip'". I double checked the md5 of TWRP, /e/ and Intelli Kernel zip's, reflashed TWRP, flashed IceMan's TWRP recovery, wiped all partitions, formatted data and re-installed /e/, tried Havoc ROM, but I still got the same message. The problem wasn't only with the kernel, but also with some (not all) other zip's like A2camforS5_TWRP_v1.4.zip and even Magisk (which flashed fine) modules like A2camforS5_Magisk_v2.zip were not flashing (the procedure got through, but once the phone restarted the module wouldn't show up). On my previous SM-G900F klte phone everything was working fine. (And yes, TWPR's check md5 option was disabled, so this wasn't the problem)

After a bit of chatting on Intelli kernel and /e/ Telegram support groups I found out it wasn't the kernel or /e/ problem and that I should go back to stock and start all over. I had a full NANDroid backup from my previous phone so I renamed the backup folder to match the new phone serial (so it would show the partitions to restore in TWRP) and as I (and nobody else) didn't know where the problem was I restored all partitions. Everything went through as it should except modem, which showed an error saying something about being read-only and efs, which went half way through and then gave an error I don't remember (but can reproduce if needed). The phone wouldn't boot to OS (it was stuck on SAMSUNG logo), so I re-flashed TWRP and /e/ again and tried to flash the kernel or other zips but they were still giving me "digestion" problems... but it got worse! Now when I boot to /e/ I'm not even able to use the phone normally as a pop-up saying "Bluetooth app has crashed" and "Bluetooth app keeps crashing" shows up continuously even if Bluetooth as other wireless connection work just fine. Did I mess something up with the unfinished efs restore?

How can I diagnose the problem and unmess my phone? What steps should I take? I'm afraid of bricking my phone if I just start to do random stuff so any useful information would be appreciated! Please help!

EDIT: Even if my description of the procedure looks like I flashed a ton of stuff all at once I have just WRITTEN A RESUME AS CONDENSED AS POSSIBLE - the procedure took me more than a week of flashing ONE THING AT A TIME and testing if everything works fine. At no point in my flashing procedure there were more than three things present on my phone: TWRP, ROM and MAGISK as kernel and camera mod refused to flash anyway. To exclude Magisk being a problem I clean installed everything so I had just TWRP and ROM and I was getting the same problem. Then I reflashed TWRP only, using the IceMan version (because it presumably solves all flashing problems) retested, then flashed /e/ only, retested, Havoc only, retested... well, you got the picture!

I was doing everything under the guidance of Intelli kernel Telegram support group members until I understood the problem was not the kernel, nor TWRP/IceMan, nor /e//Havoc and went with the stock recovery through TWRP and messed my phone beyond Intelli kernel Telegram group's scope.
