I have been using the phone in Glove mode for the past 6 months due to the touchscreen being unresponsive. As of yesterday, even Glove mode isnt working for the back and home buttons! Although I have liked the phone otherwise, this has seriously put me of getting another Sony phone in the future. Ive only had the phone over 2 years. My previous Moto ran for 4 years before I upgraded.
[G4 General] BIG_BADASS:
What would be the PC equivalent of Custom Recovery software like TWRP?

Would it be something like Acronis TrueImage ?

Also, would it make sense to say that a locked bootloader in a phone (PS: Notice I won't say 'Android Device', because the bootloader comes into play BEFORE the Android OS) is the equivalent of having 'secure boot' enabled in UEFI in a Windows PC? Thereby implying that the process of disabling Secure Boot in UEFI in a PC is the same as unlocking the bootloader in phones?
[G4 General] SpyderAByte:
I really don't think you get how phones work bro. Unlocking a bootloader can only be done by manufacturing or through more aggressive means when possible. The H812 still hasn't had its bootloader unlocked by lg and at this point probably never will
[G4 General] BIG_BADASS:
That doesn't answer my question. I asked the theoretical side, not practical.

Before you do anything, you must understand the FULL boot sequence and structure of Smartphone with ARM chipset, and compare it to Intel x86 Chipset..... and know the relationships well... THEN only you can safely say "I know this" ... THEN only you can safely play around and tinker with the smart phones.....

I thought I knew alot.. but turns out I know NOTHING.... so I go back to square 1 and learn EVERYTHING from scratch again.....

Before I do anything, I must familiarize WHAT is TWRP.. You can say "TWRP is custom recovery", okay, 'WHAT IS CUSTOM RECOVERY' ? You must be able to clearly explain what it is, what parts of the boot sequence it affects.... what is the equivalent in an Intel x86 PC of TWRP or custom recovery????

WHat is a ROM? We all know ROM in smartphone world is more than just the operating system... So what other components does it replace besides the operating system???

We have to think like this and analyze EVERYTHING, all the relationships between all the entities.....

I am now learning about EMBEDDED LINUX ... and the boot sequence of it... as smartphone is just another version of embedded linux......

This is what I'm doing now... when I am familiar with EVERYTHING.... then I will tinker....
[G4 General] SpyderAByte:
Secure boot on windows acts as a UEFI (modernized motherboard BIOS meant to work better and faster with x64 and newer systems)

Locker to prevent UEFI from booting into unsigned/unrecognized system images (as far as I know, anybody feel free to correct me)

Bootloaders on smartphones would be the equivalent of a UEFI for the arm architecture. Meant to guide the system into booting from a specified mount. Bootloaders are coded by the manufacturer, either locked or unlocked. Unlocked bootloaders provide a way for users to enter recovery mode and potentially flash unsigned/custom images. If the manufacturer decides to lock the bootloader, the only options are wait for a way to unlock from manufacturer or find a way to crack it if you have the know how

Some manufacturers use the same bootloader for all or most variants of one phone, or can use a different bootloader for each variety of a phone, choosing which bootloaders to unlock or leave locked

For example with the Lg G4, the international variant H815 I believe is unlocked, while the H812 is still to this day locked, while unfortunately their has not been enough interest in trying to reverse engineer or find a loophole if even possible
[G4 General] BIG_BADASS:
Thank you bro... now we're getting somewhere....

So PCs also have a bootloader.... but the way I understand, "Bootloader" in the smartphone is a combination of BIOS and MBR in the pc world, right? It is all combined into one entity called "Bootloader"...

Also, the MBR usually has a Stage 1 bootloader, which points to a stage 2 bootloader, which is installed somewhere in the permanent memory (hard disk in PC).... but this structure is not the same in smartphone I believe?
[G4 General] SpyderAByte:
The arm architecture is completely different than the x86 or x64 architectures.

As Asus and MSI and acer etc have their own bios,

Samsung, lg, HTC Huawei Google etc have their own bootloaders. Twrp for example is a custom open source bootloader that anybody can get the source and add to. Phone companies do not give out the source code for their bootloaders usually and it is in their own power to lock and unlock them
[G4 General] BIG_BADASS:
Yes, that would be the easy way around...

I have the H815 now which I got in exchange for H812... anyways.... if I didn't have it the hard way, I wouldn't learn anything..... If I had the unlockable H815 from day 1, I wouldn't be this curious... therefore I wouldn't learn.. I'd just be living in ignorance thinking I know everything there is to know .....
[G4 General] SpyderAByte:
Why don't you start by finding the twrp out for the h815 and tinkering with it, making it your own. Try finding a stock ROM and tinkering with that building your own. Plenty of guides around the internet. Learn java and take flight bud
[G4 General] BIG_BADASS:
Yes, in the x86 world they do have different motherboard architectures, hence different BIOS's ... but the rest of the boot sequence follows the same order......

So that brings me to my next question... why is it that we can hard brick a phone, but not a PC? I mean.. technically it is possible to brick a PC if you screw up a bios flash.... but that just leads me to believe a "ROM" in smartphone world actually consists of BIOS + OS ...

So that leads me to wonder.. what else has combined functionality? What is the BIOS equivalent in Android? I mean.. technically it is possible to brick a PC if you screw up a bios flash.... but that just leads me to believe a "ROM" in smartphone world actually consists of BIOS + OS ...

So that leads me to wonder.. what else has combined functionality? What is the BIOS equivalent in Android?
[G4 General] SpyderAByte:
The bootloader partition/iso and the data/android partition/ROM are 2 different things

You can independently swap your recovery if it's unlocked and keep your data. Or you can independently change ROMs and keep your bootloader. You don't seem to understand this pretty basic concept

You can brick a phone flashing the bootloader incorrectly or by flashing the ROM incorrectly

Likewise on a PC if you flash the bios/UEFI incorrectly you can brick your motherboard, and corrupting your OS installation can cause issues

The reason you've bricked phones more than you've bricked computers - when was the last time you tried flashing a custom bios or UEFI? Or a version of Linux/windows that your bios won't allow

Computers are usually pretty plug and play so you can swap HDDs/ram/processors and simply upgrade needed drivers to works

Smartphones are greasy and closed source and the manufacturer usually wants it their way, that's why you see them blocking root access and custom roms
[G4 General] BIG_BADASS:
So basically, the ROM is more than just the operating system, no? Flashing a rom in smartphone is NOT exactly the same as installing Ubuntu or Debian in a PC, right? There's something else you're replacing, am I right?

Also.. the way I understand... Bootloader is the very first software that runs once you power on the smartphone? (equivalent of BIOS) ?
[G4 General] SpyderAByte:
The ROM is the operating system, the included apps and packages and any other information that android needs to run after the bootloader
[G4 General] BIG_BADASS:
So when you flash a rom, you're not replacing the original bootloader? Or BIOS?
[G4 General] SpyderAByte:
No as I stated in my previous post. You can use your bootloader or a PC through fastboot to flash ROMs as long as your bootloader is unlocked

On a galaxy for instance you could first install twrp if possible leaving your stock touchWiz ROM perfectly intact but now you have twrp

Then later you can use twrp to install paranoid Android or CM for instance, replacing your stock touchWiz ROM, but leaving your newly installed twrp untouched

I used to have a galaxy s4 Canadian variant, and the bootloader was locked and still is to this day. The only way to flash a custom ROM was to bypass the stock bootloader using a method found by someone experienced with Samsung bootloaders (a rogue Samsung employee iirc)
[G4 General] BIG_BADASS:
The final outcome is the same, yes, but bootloader and BIOS/UEFI are completely separate, right? X86 PCs have a bootloader called NTLDR and it comes into play after the BIOS has finished POST and given control to the MBR....

BIOS > MBR (contains stage 1 bootloader) > Stage 1 bootloader points to Stage 2 bootloader in the HDD

Or is the functionality of bootloader and bios combined into one unit in the smartphone?

---------- Post added at 07:09 AM ---------- Previous post was at 07:05 AM ----------

So TWRP comes into play before the operating system is loaded, correct? Meaning if you flash a corrupt operating system, you can still format the drive, because TWRP is on a lower layer?

So you can think of TWRP as those Windows Recovery disks?
[G4 General] SpyderAByte:
Do you understand how partitions work? (Not attacking, honest question)

Your bootloader would sit on one partition of the phone emmc(like a small solid state drive/kind of like an sd card chip)

So your partition table would look kind of like this

Emmc1 - /boot (bootloader tells android to boot into recovery, download, fastboot, or android rom

Emmc2 - /recovery (recovery partition. User interface of twrp for example)

Emmc3 - /download mode (used to flash zips)

Emmc4 - /data (android rom that you install

Emmc5 - / (the root folder of your phone, where your storage starts

If you remember getting a 16gb iPhone or iPod and wondering why you only got 9-11gb when you have 100% free space, it's because the emmc is rated for 16gb but the data/ROM uses 5-7gb
[G4 General] BIG_BADASS:
Sorry man, I'm from the PC world.. this makes no sense to me.... please relate all the functionality to it's PC equivalent...

Also, what is the boot sequence of the smartphone? Does it have a BIOS? MBR? Hard Drive? RAM?

If smartphone doesn't have all these parts, then what part of the phone does the job of the BIOS, MBR, Hard drive, RAM, bootloader, etc?

---------- Post added at 07:27 AM ---------- Previous post was at 07:20 AM ----------

Maybe my approach here is wrong, maybe I shouldn't try to relate everything 1 to 1 ?

---------- Post added at 07:48 AM ---------- Previous post was at 07:27 AM ----------

Also, lets say you format the entire memory of the phone, and reinstall Android.... will it automatically create all these partitions?
[G4 General] SpyderAByte:
Holy **** man you say you know computers but it's almost the same as Linux. Android uses Linux at its absolute core so alot of it is pretty close. Look up a healthy Linux partiton setup and compare to my half assed partition table above and you'll see it's almost identical.

A HDD, SSD, or a memory block (phone internals, usb drives, sd cards) all can have seperate "partitions" which are basically seperate simulated drives, and all have a master boot record telling the device where to start.

There is a boot partition on the memory block which holds the core bootloader files and tells the phone what to do first.

If you hold down the recovery button it will tell the phone to boot to the recovery partition. If you hold down the download buttons it will tell the phone to boot into the download partition. If you allow the phone to boot regularly it will tell the phone to boot to the android /system partition which is where the android operating system is held

I can't explain how this works compared to windows because windows does its own thing in regarding to booting and it is not in my spectrum

The paranoidAndroid.iso file system you would try to flash for example would hold the

/system(android os)

/Data (user data and apps)

/ Or /root (main read/write accessable storage for user)

/Root would require root access to be able to get into and from there you can access the /system and /data mountpoints to modify system files, without root access you are usually not even able to view these folders
[G4 General] BIG_BADASS:
Yes I know Linux... but there is a HUGE difference between Embedded Linux and GNU/Linux you run on PC.....
[G4 General] SpyderAByte:
If you were to completely wipe the phones internal memory, formatting each seperate partition into one blank one. You would need to find a way to recreate the partition table, install the bootloader onto its proper partition

Then you would use the bootloader to either recreate the partitions for the android rom, OR the ROM could self unpack and create it's needed /system, /data, and /root partitions

When you said, ghost touch did you mean screen display retention (Image Burning after effect).

If so then it's common for LG G5 and you just can't fix it.

I am currently at work right now so I can't research much. I was wondering if anyone has done this yet, or know where I might be able to find a tutorial? If so, I was wondering your opinion on Wear 2.0 for the Z3. I am seeing so many posts of people regretting updating their watches. Before I even wanted to make an attempt, I was going to check around this forum to see if I'd be able to revert/downgrade after if I end up disliking it.

[Nexus 6P Q&A, Help & Troubleshooting] lonshlon:
Hello all,

I recently dropped my phone, shattering the screen and rendering the LCD useless. I need to use my phone to access some important messages, so I am trying to use Android Control to emulate my phone until I can get a new one. The problem is I didn't have USB debugging turned on when I dropped it. To fix that, I am trying to use ADB and recovery mode to turn it on, but ADB can't/won't recognize my device. I have installed the universal adb driver and my phone shows up in the device manager, but when I run "adb devices" in the command prompt, nothing comes up. Any help is much appreciated!

Thanks!
[Nexus 6P Q&A, Help & Troubleshooting] tech_head:
Did you have TWRP installed? (Unlocked bootloader?)

If not, I don't know of any way to turn on ADB.

If TWRP is installed you boot into recovery and you are good.

[OnePlus 5 Questions & Answers] DJGREEN1980:
Both cost the same. Which would you choose? Both are good for rooting and roms. OP5 probably has the upper hand though. But the U11 has much better audio and camera.

Whats the audio like on the OP5 through earphones?
[OnePlus 5 Questions & Answers] iamelton:
i have an OP5 and a friend of mine has U11..

- what region are you in? here in hong kong U11 is more expensive than OP5.. (generally HTC is an expensive brand here..)

- since i came from the nexus line of devices, i would consider OP devices more friendly in tweaking, rooting, etc.. (i just read from a XDA portal post that HTC seemingly changed its policy on unlocking the bootloader in the developer unfriendly direction.. unconfirmed info but worth mentioning..)

- as my friend and i both do not demand very much on audio quality (i still listen to MP3s in my OP5), i cant comment on this aspect..

all in all, i think these 2 two are quite different products aiming at different target groups.. what you choose depends on which group you are in..

if photo (and maybe audio) quality is what you are after, go for U11..

if you want to play around with custom roms and various tweaks, definitely OP5..
[OnePlus 5 Questions & Answers] MrWilsonxD:
I agree! I think the u11 is more towards audiophiles (with no headphone jack........? :confused: ???)

Boom sound is back and better than the htc10.. But I doubt the u11 will ever come near the size of the dev community for the oneplus 5. Different devices for different purposes. Think the u11 is an okay device, I wouldn't recommend it, I think waiting on the pixel xl 2 would be a better bet.. Or the next axon with sd 835..

HTC U11 is 650+ Tax = 700$

But 700$=/= 479$ or 539$ they are definitely not the same price.. (no taxes are charged by oneplus, my device was 539 exactly.)

Hello every body

I have been watching this great forum for a while and finally signed up. I have a problem:

Suddenly all the navigation software that are loaded in my Tytn II are not working. I use Garmin mobile XT and Destinator 7 for navigation. They were working fine until today morning when one of my friends played around with my device. He admits he have no idea of what has happened. Both programs now show the welcome screen and then nothing happens. they dissapear and the home screen shows up

Any advice???????
[Tilt, TyTN II, MDA Vario III General] Farsquidge:
Go To Start/Settings/GPS Settings and make sure it is 'GPS program port' set to COM4. Under 'Hardware' - 'GPS hardware port' is set to (None) Baud rate 4800. Under 'Access', check the box for 'Manage GPS automatically'

See if that works:)
[Tilt, TyTN II, MDA Vario III General] alilegacy:
Thank you for taking time in my post

all are as you discribed but the problem is still there ,
[Tilt, TyTN II, MDA Vario III General] Farsquidge:
Ahh, hmmm. Not sure what your (if you still call him that?) pal did then.

I suppose you have tried a soft reset?

If you have the you may need to back up your PIM and personal data and do a hard reset. You will have to re-install all your apps after that.

Hang about a while before you do. Someone on here may get back to you if they have seen something similar. :)

Best of luck.
