Download mode?! Flashing possible via fastboot?

Hi everyone,

Having read loads of threads it looks like the only way to root the S7 is via the Download mode.

I have tried all I could but I cannot boot into Download mode. :eek: Power + Vol Down + Home flash the screen a bit and that is it, device does not even boot. I have to let go of the buttons and then boot it with just "Power" button. Also if I try to boot into recovery I only see Droid with open torso in red. Should I try flashing stock recovery? Can someone share it or point me where to get it please?

The best custom boot I get is Fastboot (via adb) or the chinese-menu that allows to wipe the device clean or test sensors etc. When trying to flash TWRP via fastboot I get "FAILED (remote: invalid kernel & ramdisk address: images overlap)"

I have an SM-G930F Snapdragon device (confirmed by CPU Z)

Is there a way to flash TWRP or root the device via fastboot at all? :confused:

Never had a device that I couldn't boot into Download or recovery mode.....

Automatically enable Power Saving Mode

I have Galaxy S2 Classic (SM-R732) with software version R732XXU2CPC5. Is there a way to automatically enable Power Saving Mode when battery power gets below a certain percentage like I can with my S6? I have noticed a prompt to enable power saving when the battery gets to 15%, but if miss the prompt and I don't hit the checkmark, it stays on normal power and dies.

Also, do Samsung reps monitor this forum? If there is no way to do it automatically, can this feature be added in a future update?

Service Mode?

Has anyone with root tried or had success with accessing Service Mode?

Perhaps the method that worked on the VZW S6 would work for the S7.

flashing an official firmware might solve it?

Thanks,

Airplane mode will not turn off

Hi all, I've been battling this problem for days now. Airplanr mode is stuck 'Turning off...' and wont connect to my mobile carrier. Things I've tried:

Restarting phone with and without SIM inserted
Factory reset from setting
Factory reset from recovery mode
Flashed to the same build twice using the flash from SD card method.

I have no idea what to do next. I doubt it's a hardware problem as the phone detects the sim card when I put it in and asks if it's O2 pay and go or pay monthly, so it can even read it, it's just the phone wont come out of airplane mode.

I am on holiday without a PC but feel free to post ideas that requires one. I would rather not root or s-off the device just yet, and would rather stay on stock ROM as it's still in warranty. Problem is, it's in the UK and the warranty is held in Taiwan, which means sending it internationally to get it fixed. It's also a problem as there is a language barrier between me and their support for phone calls and their live chat button appears to always be greyed out.

Need help! Private mode won't work

After rooting my phone, private mode won't work, any ideas or fix:confused:

Stuck on TWRP, cant ADB or Download mode

So I've been messing around with this phone and I've gotten it stuck in TWRP before, but that version had a download mode option and I was able to fix it using odin + the default firmware. This version doesnt seem to have it. My phone is unrecognized by my PC (previously it was), I can't seem to use universal drivers, and ADB reports no devices connected. I have an SD card so I was wondering if there is any way to fix it using that? TrapKernel is also installed. I don't have access to an OTG cable but I'm assuming its my only option? Thank you in advance.

tried this said it was not found. (tried multiple times)

Code:

---

dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/fota

My Moto 360 is stuck in demo mode.

So I don't even know when this started but it's stuck in demo mode. Yes, I know you can factory reset by holding the button and then click unpair & factory reset but that simply does not work at ALL. It will just reboot and stay in demo mode. I have no idea what to do.

S5 Screen black (but worked in download mode)

Hi,
so my S5(SM-900F) shows a black screen, but is otherwise functional. I don't know if it's a software or hardware issue, neither really makes sense to me.
Here's whats happened:

1. I wanted to flash cyanogenmod, phone seemed functional


2. Tried to flash twrp (3.0.1) with heimdall, got a bunch of errors


3. Tried a bunch of stuff, got it to flash twrp using heimdall-git


4. Phone got stuck in a boot loop


5. At this point I was annoyed and decided to reset it, which I did with kies

Here's where the screen issue started. After booting the screen was black. Phone showed S5 logo upon startup, download mode worked fine.
Touchscreen worked (managed to activate Talkback. In Hungarian), so the hardware seemed fine.

1. Googled and tried the million tips to fix a black screen, nothing worked


2. Screen randomly worked until reboot/lock


3. Fully charged the battery, screen worked until battery was at 70%, then black screen after locking with power button

Here's a kernel log from around that time:
dmesg
Nothing sticks out to me, log shows the backlight being adjusted which might be related.
This is the log I saved however, when I looked at it in the console I saw a few more things (see below)

1. Hoping it was a weird software issue I tried to flash cyanogenmod again, this time got into recovery (had to hold Vol Up+Home for more than half a minute), but got "kernel not seandroid enforcing" upon boot, then black screen and periodical vibration


2. Reset again


3. Wanted to see whether the screen would fail after some time in download mode, worked until battery was empty


4. Suddenly the screen's black in download mode, too, even though it worked for days

Here's a current bugreport.txt containing

Code:

Those I also saw before the previous dmesg.
The -19 read bytes seems especially dubious, from a quick look at the source it does not seem like an errno, don't know if it's related to the problem anyway.

Current Android version: 6.0.1
Kernel: 3.4.0
Build: MMB29M.G900FXXS1CPG9

So what's going on? Is this some weird hardware issue? Do the ways download mode and android control the screen differ? What difference does the battery make?
Is it software? Both?

I've searched the forum and found e.g this, but nothing that helped me out.

Thank you for your help,

Request APP for default location mode

On touchwiz 6.0.1, I observed if disabling location via the quick toogle, and then enabling again, it will always be enabled in high accuracy mode even if previously battery saving.

Is there a xposed module or app to fix this, if not can a dev consider making one?

Thanks

What's the Best Way to Get Into Recovery Mode?

So, this is a really dumb question, but I suppose better to ask than mess something up.

So I finally rooted my Z5 Compact with this excellent guide, and everything went off without a hitch. The guide had me set my bootloader back to "Bootloader unlock allowed" before I was done, which, if I'm understanding things correctly, means that I relocked the bootloader (or at least, it looks locked).

My issue is this. I'd like to install this audio tweak, but the instructions require me to put the device into Recovery Mode (CWM or TWRP or Philz Recovery). First, what's the best way of doing that, and second, is that going to require me re-unlocking my bootloader, or is my bootloader actually already unlocked?If I have to unlock my boot loader again, does that mean I need to restore my DRM keys again?

Thanks for any help anyone can offer!
