Galaxy S6 :: Flashing Stock ROM - Bootloader?
Feb 12, 2016
I'm about to fully flash my device back to stock. I have a o2 UK variant s6. I have downloaded the correct 5.1.1 rom via sammobile. However the worry I have is about the bootloader, do I have to do anything with it.

I have flashed various version 5 stock firmware's and the latest 6.0 using nexus tool kit, as well as specifically flashing only stock recovery using the tool kit and I cannot load into the stock recovery. I've spent hours looking for information on manually flashing the stock recovery without the tool kit but have found the instructions very vauge. Any information on flashing manually only the recovery would be very useful or information on why I may be having this issue.
I know every time i flash a rom it only shows about half of my internal storage. I have a 32gb version. So I end up having to go into a recovery "temp flashed" using the tool kit in order to clear some information and then i get my 32gb's back.
I"m wondering if the space being auto allocated or partitioned is interfering with the flash of the recovery..

I had so many problems in the last days. I flashed the first INU 5.1.1 version on my G920I, after a few problems flashing TWRP. Finally I got the phone working and no major problems until last days when battery started to malfunction.
Anyway, after that I tried to flash the latest INU 5.1.1 version (G925IDVU2COGA_G925IODD2COGA_G925IDVU2COGA_HOME.ta r) but the phone couldn't start the Odin process. Then I tried another roms but nothing (all of them 5.1.1) after that I flashed the TWRP and made a stupid "factory wipe" and then my device was soft bricked.
The phone was on boot loop.. Finally, I splitted COGA rom in parts (modem.bin, cache, etc) and flashed system separated from the rest ROM. This worked but the only file that wasn't possible to load was sboot.bin cm.bin. Anyway, after that I tried to reflash COGA in one part but nothing. Finally I used the COF room (INU 5.1.1 from sammobile) and it was flashed full with no problems via Odin but now my device has the TOUCH SENSOR INVERSED. when I type in the right the letters on the left side of the keyboard are pressed.
By now I don't know what to do. Except that I am trying to flash a modded stock rom to get things fixed .

I have the S6 with 5.0.2 and CSC ITV (AP:G920FXXU1AOCV, CP:G920FXXU1AOCW, CSC:G920FXXU1AOCN). Since I leave in Greece, I tried to flash through odin the Stock firmware with CSC EUR but I had fails all 4 times. Tried with both odin 3.0.9 and 3.10. The problem seems to be the hidden file in the end, because everything goes fine until that moment. The result is soft brick. What should I do?

SM-G920.
I tried renegade rom and wanted to go back to stock, but I can't seem to get rid of the boot/splash image it puts when you turn on your phone.
Is there something special I need to do when I flash stock firmware with odin?
Also, as I have sprint, should I be selected RTN for sprint? I had done that, was that bad?
It seems telling twrp to do advanced wipe of system and a bunch of other stuff that apparently is not normally wiped did it.

my Nexus 5 has recently run into a problem where it suddenly decided to get stuck in a bootloop. I figured I could just reflash the stock rom via the boot loader with the wugfresh root toolkit but that unfortunately didn't work. But by doing this I noticed that my bootloader was not staying unlocked when I try to unlock it. Every time I unlock the boot loader and it restarts the bootloader automatically re-locks. I then proceeded to try and manually flashing the stock rom files individually and unlocking the bootloader each time I flash a file which was really annoying. It still hasn't worked and I'm starting to get worried because I've also started to notice my recovery can't really factory reset or wipe the cache. Instead I get this message at the bottom of the screen:
E:failed to mount /cache (Invalid argument)
E:Can't mount /ache/recovery/log
E:Can't open /ache/recovery/log
E:failed to mount /cache (Invalid argument)
E:Can't mount /ache/recovery/last_log
E:Can't open /ache/recovery/last_log
E:failed to mount /cache (Invalid argument)
E:Can't mount /ache/recovery/last_install
E:Can't open /ache/recovery/last_install
E:failed to mount /cache (Invalid argument)
So now I'm completely stumped, could this be the end of my Nexus 5?

Is it possible to make a backup of bootloader? If it is, how? I am not talking about kernel (boot.img is the kernel, correct?), system, recovery, or data. Bootloader.My Nexus 5 came with bootloader version hhz11n. The factory image from Google (4.4.4) has bootloader version hhz11k.
How different these two are, but since hhz11n image can't be found anywhere, I want to back it up before flashing to Lollipop or Marshmallow.
My Nexus is still running 4.4.4, bootloader unlocked, rooted, with TWRP installed.

I flashed my LG G3 Because i felt that the sound was not working anymore and that it can be a software issue which it was a hard ware issue ( loud speaker wasnt connected because of screw) Anyways preformed the stock FW Flash following the guide that highonandroid provided to go completely back to a stock rom. After flashing i restart phone and the boot takes forever until it finally hangs on the tmobile screen. there was a point where i left it over night to see if it will turn on but it still hung for a good 8 hours. Ive done everything i can which can be that i preformed atleast hundreds of hard resets but nothing is working.. there was a point where i did manage to turn it on then i tried updating to lolipop and when it reboots the bootloop is back..

Bootloader is unlocked by the way.

The whole range not just the bell vibrant. Is the bootloader on these things open? Anyone running froyo on it yet? Or any custom roms? Thinking of getting the TMobile version, but it'd be pretty useless with a locked bootloader

I think I am having GPS problems with the latest BOGG baseband, I intend to try to downgrade to 5.0.2 baseband, I am not sure if this is possible or not. I know that you cannot downgrade from 5.1.1 ROM to 5.0.2 ROM, but not sure about baseband.

I have purchased a S6 from Amazon, but the device is branded with Swisscom, with an awful boot logo and sound, and a few specific apps. I'm waiting for a nano sim, so for now I don't know if the phone is also simlocked.
I intend anyway to install custom roms, so I don't care much about this, however I can't find out whether the bootloader is locked or not (in which case, I'll have to send it back to Amazon I guess).
The device is a SM-920F, I made the OTA update to 5.1.1 upon powering it. Not sure what the bootloader and rom exact versions are, but I will add them to the post if necessary.

I recently got a Samsung Galaxy s6 Edge. Loving the phone, but was surprised not to see raw support and shutter speed ability in the stock camera app, as last may I was convinced I had read that it was going to have an 'exciting' camera update. After some research, I discovered this had been updated and implemented in Android 5.1.1.
So does this mean even with the impending 6.0 update, that the only way to use raw or tinker with the shutter speed will be via a third party app? If so that seems a bit lame..
I do love my lg g4 but compared to the s6 edge it looks ancient, the camera capabilities are simply amazing though. That's why I don't get why Samsung hasn't made it accessible from their own app?

My phone is currently rooted, with a different kernel and running deodexed XtreStoLite. How to go back to stock? I want to trade my phone in soon at T-Mobile and I know they'll notice the phone is rooted, since it says "kernel is not seandroid enforcing" when booting up. Everything works fine, though. I know in most people's case that text only shows for bootloop, but mine works fine.

I'm new with S6 development. Been playing with SONY devices since 2011. So the question is, can I flash a 920F stock firmware on a 920I device? Will brick my phone? Does it need a special process to make it work? I really want to flash 920F on my 920I and I need to know if its secure.

How do I get back to stock, from a custom rom?
I did a backup of stock, with TWRP, but can I just restore it or do I need to flash stock firmware with Odin first? (I'm on XtreStoLite right now).
Just don't want to brick it, so unsure if I can just restore, or I need to remove the custom rom before restoring.

I have a SM-G920F phone and I recently flashed the UK version of Lollipop to be able to participate in Marshmallow beta program. I didn't like it because it didn't support my gear VR and I went back to Lollipop. Now I have the UK version installed on my phone and I can't get rid of the Android 6.0 beta OTA software update notification.
So I would like to flash the Nordic countries firmware but my pc is broken and I don't have admin permissions for my pc at work. It there a way to flash it without a pc?

Is there a non intrusive (as in rooting not required) method for "backing up" and "restoring" a Samsung S6 (SM-G920I) stock ROM.
Not interested in any custom rom nor any tinkering. this is strictly for recovery option should the operating system ever get corrupt or get malware.
