I updated the OP with new method that will hopefully cut down on certain phones bricking. I have no control over why certain phones brick when flashing combination firmware. Its most likely one of the partions over time has gotten corrupted.
2023 SM-G955U/U1/W Rev8 Root Method Android 9 (snapdragon models) Via Bootloader Unlock Token
- Thread starter jrkruse
- Start date
Does this method allow us to install the Android 11 GSI? If not is there any other way to flash some variant of Android 11? Samsung and T-Mobile customer support apparently can't unlock my bootloader remotely so they said I could take it to a Samsung authorized store
There is no bootloader unlock. You are stuck with samsung android 7 if you want root or android 9 stock
So recently I got a Samsung Galaxy s8 plus as a backup and it has safestrap already on it. It is super buggy and laggy in my opinion and I would like to restore back to factory stock however every Odin file that I have tried gives me a auth fail.. I don't know what to do if anybody has any kind of information on this that would be great. Not a noob. Which confuses me even more lmfao
download the one from the link in the xposed repo, that one let me do it after clearing chrome and stuff with titanium backup
Well its been a fun ride for the 8 series but from here on out I do not support or encourage rootIng this device. A good number of devices have become hard bricked from simply flashing the combo firmware. I don't know why this happens to only some phones possible a past OTA corrupted a partition on the phones or something. Whatever the reason I have decided to pull the method and will no longer support it. Please don't ask for files or help I will provide neither. I will leave rooted and non rooted safestrap roms up for those that still have a rooted 8 series.
Crackhead superpowers? I'm gleefully here for that!Now I've had a lot of phones as someone who makes a living in the digital world (I've got more flip phones than Jitterbug), and out of all the phones I've owned(myself)/modified/repaired/ or even just looked at for somebody... the S8+ has got to be my all time favorite. Why? Because of it's steel ball durability and the sheer power this thing has.
By the time the phone was released I had already managed to obliterate the first one with a brake rotor (pro tip - use a headlamp when working on cars instead of laying the phone on the ground with the flashlight on). I still remember the look on the guys face when I brought it in and asked them to replace the screen. "You want to replace the screen on a phone that doesn't even come out for two more weeks?" And if everyone remembers this was the first bezel-less-glass-front-and-ass phone to come out. The looks from everyone in the store were priceless. Not only did this idiot manage to get a new phone before its release; he also chose not to pay the $12 insurance and had to pay $600 because the 2 week grace period had run out literally 2 days before. I got my replacement and things went on normally from there.
Fast forward some amount of time later and the phone holds up well but gets boring on the stock rom. I eventually finish off the lease and Sprint unlocks the phone OTA. I now own a "factory" unlocked US variant of the S8+ (SM-G955U) which didn't even make sense to most at the time because I had gotten the phone so early my lease was up early.
Then came the modifying... Now just like the Note 3, the S8+ is a truly unbrickable phone. Yes you can brick it very easily, but there is always a way to fix it regardless the damage you do to it. Using QFIL and cutting out the middleman, you can always bring ole' Bessie back to life. In my time of owning this phone I've bricked it probably everyway imaginable. Trying to flash to the boot partition, leaving it in the sun,flashing an Exynos variant file, and even trying to boot a Windows Mobile image onto the phone. Physically I know every pieces of the phone by heart. I've taken it apart an illogiocal amount of times; spent 6 hours removing the glass back for the first time (no iOpener). I've even modified a S9+ frame to take the S8+ motherboard. To this day the phone still has some of the smaller parts from an S9+ in it. Once again here I am unbricking it from kernel panic (die+0x28c/0x2d0) because I was trying to use the XTouchWiz for Oreo instead of Nougat. :laugh:
Not to mention when this phone is rooted it's got crackhead superpowers... so that's my story. Figured I'd share it.
Thank you jrkruse for your ongoing development on this platform. Thank you elliwigy and anybody else who has contributed. It's been fun and hairpullingly frustrating but there's no better feeling than playing with the monster you've successfully created. Good work and godspeed.
Could you please elaborate? I used to run CM on all my phones, and it's finally time to prioritize freeing my wife's and my vze G955Us before I am forced to just junk them and rely on the Pinephone Pro, as incomplete as it is
Well, I have a Verizon G955U with Android 9 (and v8 bootloader) and am getting lots of mixed results when I look into how to liberate it without turning it into a somewhat less desirable masonry block. As you said 'it took a bit to figure it out' I was hoping you could elaborate on what you needed to figure out, so as to help others with such phones. End goal is to run a proper AOSP rom, ideally latest LineageOS.
I didn't mess with Lineage or any other rom besides the nougat rom OP provided. This took me a bit to figure out because I didn't realize I had to flash the combo firmware and use the bat file in the Telegram first in order to get safestrap. Once you've got safestrap the rest of the process follows the guides provided well, you just gotta make sure you join the Telegram and have all the correct files for your device.
Awesome. Thanks for the feedback. I guess I need to set up a Telegram account, and not worry about running a newer rom.
I'm wondering, do you think I will get better performance rooting the G955U or applying Verizon update #39? Of course I'm on my 4th or 5th update delay so it's **** or get off the pot time.
Added new method back with understanding that it may brick certain devices. This method is easier than previous method
