Bootloader unlock theory 2 - Sprint LG G4

I possibly found that the lg g4 can connect a serial console when in fast-boot and android with limited access, and that the boot-loader is based on little kernel
codeaurora.org/blogs/little-kernel-based-android-bootloader
It may be possible to connect uart via serial and map out how the bootrom loads the sbl and (aboot (bootloader))and possibly find a way to unlock the boot-loader
newandroidbook.com/Articles/aboot.html
so far acessing fastboot with a nuked laf partition only specific fastboot commands work. can not get oem-id or reboot/continue via fastboot
console=
/dev/tty
/dev/ttyHS0
/dev/ttyHSL0
/dev/ttyHSL1

Try posting this in here: http://forum.xda-developers.com/g4/help/unlock-technical-steps-to-make-unlocked-t3165391
Or even the general G4 forum; the audience appears bigger and you'll probably be able to get more brains taking a look at this!
It's quite interesting.

Dude, I was literally coming here to see if anyone had tried anything like USB serial console the way you'd do with like a raspberry pi or a more recent thin client and found this thread with the search feature.
I'm glad to see that it does, in fact, work. I was about to pitch the theory, but it seems you've not only arrived at the same theory, but have tried it yourself. +thanks for posting the results dude. Much appreciated. Hopefully this will lead to some kind of progress otherwise I'm just going to use an upgrade to get something else and sell my G4. I'm really getting tired of the total lack of ROMs. This isn't 2008 where only a couple carriers have Android phones and the developer base is tiny. What company thinks it's SMART to create only one model that can have the bootloader unlocked and then NOT make that model available on all carriers at the off-contract price?!

I'm guessing there is no way to edit the LK, and implement these changes to re enable fastboot commands without it throwing some type of error due to the fact of it not being signed? -
To selectively enable any fastbootcommand on user/production build, add the command as shown below:
File: bootable/bootloader/lk/app/aboot/aboot.c
Function: void aboot_fastboot_register_commands(void)
structfastboot_cmd_desccmd_list[] = {
/* By default the enabled list is empty. */
{““, NULL},
/* move commands enclosed within the below ifndefto here
* if they need to be enabled in user build.
*/
#ifndefDISABLE_FASTBOOT_CMDS
/* Register the following commands only for non-user builds */
{“flash:”, cmd_flash},
{“erase:”, cmd_erase},
{“boot”, cmd_boot},
{“continue”, cmd_continue},
{“reboot”, cmd_reboot},
{“reboot-bootloader”, cmd_reboot_bootloader},
{“oemunlock”, cmd_oem_unlock},
{“oemlock”, cmd_oem_lock},
{“oemverified”, cmd_oem_verified},

only prob is still oh never mind i do have a twrp lol i forgot kernals wouldnt be same we would need i thing the debug bootloader for ls991 which i actally read the other day on something trying to find us one.
in theory a debug or engineering bl should overite a qfuse in a way kinda thing device model specific but firmware versions usually dont matter or at least the few ive messed with on samsungs.
im in no way a dev but if someone could possibly mod one of the debug bls for us then yes may be possible because if im not mistaken the v20s are locked as tight as ours arent they`

Can this work via lg flash tool to convert say a ls991 to h811? Is there any special ools needed like octopus box?

I dont think we can cross flash to811. Ive tried askin that one may be possible with box but doibtfull
And sprint wont unlock bl. Only lg can. They would have to basicly give u the signature to sign ure own images. Unless they offer unlock when nougats released

[GUIDE] Unbricking SamsungGalaxyMini

credits to those who found this out in other units
---------------------------------------------------------------------------------------------------
i have found a solution for this problem
by reading other units solutions (even if it's posted everywhere, i just want to share this)
this thing will solve the:
E: can't open /cache/recovery/log
E: can't mount /cache/recovery/last_log
and others
unbricking steps:
- remove sim card, and sdcard
- remove battery for even less than 30-20 seconds
- hold volume down, home key and power button simultaneously and put the battery, it will go directly to Download Menu
- open ODIN and DO NOT USE ONE PACKAGE, set the files, i used XXKPI with the 4 files, CSC, APBOOT, MODEM and CODE. dont use the ONE PACKAGE in this kind of flashing. i tested it but nothing happen so i used the other option.
- flash it, wait and done! back to normal.
i thought i should bring this up to the samsung center for the warranty
though i tried other options and experimenting
whew
thanks be to GOD.
Maybe post all the 4 files for all of us?
Luckily, I don't have my device bricked... yet.
yes, u should post a few of screens

One packages contains all the needed files at a single tar or md5 file while using separate packages you use different tar for PHONE, PDA, CSC, BOOT in Odin... There is not much difference these file are also included in the one package zip file.

Phones IMEI changed without even touching it

I have this problem - my G800F changed it's IMEI to 350695200123951. When that happened I had not touched it (no root, no nothing) at evening I still was able to make calls, but later that night it showed 'not registered on network'. I have tried factory reset, reinstalling the firmware using Kies, then I used odin, tried to make EFS backup and restore, but so far I haven't had any success. So I thought that some of you brilliant minds could help me, maybe there is a way to change the IMEI in efs backup file? The only strange thing that happened to my phone couple of days before this happened is that some random number from Ukraine called me, but for obvious reasons I did not answer it nor did I call it back. So now I'm stuck using my fathers old HTC Wildfire S, I really hope that you could help me, because I want my phone back.
SOS
Sorry no answer from me but exactly the same thing with my S5 mini g800F last week (end Sept), with exactly the same false IMEI, and I think I have now tried everything. No luck. Not the Ukraine phone call though!
Cannot get into "engineermode" which may have been a way to fix this. I loaded a new firmware, still nothing. ANY help will be appreciated but please nothing that asks me to add a "secret code" as the phone does not respond to those. I'm not an expert but got desperate enough to try my hand at a terminal emulator, it did not work. Stopped short of using SDK as the download is huge. Firmware now loaded is android 4.4.2 build number KOT49H.G800FXXU1AOG2. Heeeeelp anybody! The vendor is of no use either, just mumbling "this is a very strange thing, where did you get the phone....." (bought from the guy asking!!)
Warranty service restored the original IMEI

Just couple of days ago got my phone back from warranty and they fixed it (thought they wouldn't since it was rooted), so I would suggest doing the same thing. At the warranty center I had to explain my problem for about 30 minutes, because they believed that phone couldn't change its IMEI. Also you could try other service centers, because some of them said that they could fix this problem for about 30-50 EUR. I believe the only thing that could help otherwise is something like the z3x box, but it would be more expensive as it costs 100+ USD.
If you download the original stock firmware you can flash the IMEI number back to the phone
:S
No solution has been under warranty , the pochaine time to think about backup your EMEI
Yes yes
there is a backup somewhere between all my external hard drives, memory sticks, cloud servers... And i can't find it, too long ago and too many passwords!! But, no use telling me now to make a "pochaine" backup. I will try the reflash to older version suggestion, and see whether that gives me access to the required features. If not, it is the mountain to climb, of getting to the samsung "support" to tinker with the phone. Glad you you are sorted sunciks. A person from xda did contact me, so lets see if that bears fruit.

Nope it shouldn't. The IMEI number is installed with the firmware. So if you back it up and factory reset, it should fix it.

No, I mean downloading the firmware upgrade. It will download the new files but not install. This was long ago. Right now I get to tools to upgrade and initialise and get the message "does not support initializing" I give up!
No don't give up, just download the firmware and flash it with ODIN. If you need my to explain that, leave me an email and I'll send you the instructions.

What you propose was the second thing I did. The first was doing a factory reset with the older version of the firmware (what the phone came out with). Neither steps worked. The firmware I flashed was (Build number) KOT49H.G800FXXU1AOG2. Which btw Kies indicates as the latest version.

Relock Bootloader H811?

I had rooted my H811 but ive had problems with my phone contacted T-Mobile and they are going to replace my phone but i had flashed the 81110n kdz i got no unlocked bootloader warning but once it updated to 20i the warning came back is there any way to relock the bootloader or pull the warning help plz
Doubt it will even matter

Please help....
To lock the bootloader back is as simple as unlocking it, just follow the next steps and you'll be good to go :
Code:
adb reboot bootloader [b] (this reboots to bootloader)[/b]
fastboot oem lock[B] (this wipes all data)[/B]
P.S. This process may or will erase ALL DATA from Internal Storage.

So I kept trying to do the freezer trick over and over again until I noticed that it actually had to be in the freezer the 20 mins just to start!! If it did not it would not boot at all. It was not a battery problem, it just stopped unless it was cold. I took a chance on sending it in since it was warrantied still, and crossed my fingers that they would not do the freezer trick at the factory. They did not and a few days later I checked and it was in their repair qwe. Keeping my fingers crossed until I saw that the resolution was "Replace motherboard" Reason "bent motherboard". I know the bent mobo was BS. But hey what ever it took right? A few days later it was in the mail and my son has been using it perfectly well since then with that same battery and another he purchased! They did take the protective glass screen saver off for some reason. So Bonus a practically new phone and I still got some warranty left until Oct of this year!

So I kept trying to do the freezer trick over and over again until I noticed that it actually had to be in the freezer the 20 mins just to start!! If it did not it would not boot at all. It was not a battery problem, it just stopped unless it was cold. I took a chance on sending it in since it was warrantied still, and crossed my fingers that they would not do the freezer trick at the factory. They did not and a few days later I checked and it was in their repair qwe. Keeping my fingers crossed until I saw that the resolution was "Replace motherboard" Reason "bent motherboard". I know the bent mobo was BS. But hey what ever it took right? A few days later it was in the mail and my son has been using it perfectly well since then with that same battery and another he purchased! They did take the protective glass screen saver off for some reason. So Bonus a practically new phone and I still got some warranty left until Oct of this year!

I bought it unlocked, it turned out to be one of the models with the bad motherboard. The previous owner directed me to here so I could re-lock the boot loader. I got to the window several times but it would not stay long enough for me to try re-locking it. That's why it was nice that the phone's mobo was bad enough that it just stopped booting up! I took a chance. If it had booted and they would have seen the un-locked BL they could have told me tough luck. But I have read in many forums that LG is pretty good about this issue with the bad models. So it's a roll of the dice and lucky for me either the phone did not boot up for the Tech who handled my phone, or he saw what was going on and went ahead and switched out the mobo despite seeing the first screen screaming "unlocked bootloader!"

you were lucky only a few of them have been repair after unlocked bootloader..:good:
i have heard some complaint from other users that theirs were denied. not unlocked, but he assumes they LG tought it was unlocked because he says that when you request unlock.bin you must place your imei or serial number so they have it on record....
so you planing on unlocking this ?? HAHA if you do. i would like to see someone post a video or relocking and that it works..
No I will not be unlocking it. My son has the phone and wants to keep it locked in case. Like I said he is still under warranty.

To lock the bootloader back is as simple as unlocking it, just follow the next steps and you'll be good to go :
Code:
adb reboot bootloader [b] (this reboots to bootloader)[/b]
fastboot oem lock[B] (this wipes all data)[/B]
P.S. This process may or will erase ALL DATA from Internal Storage.

This process will remove my all data like Images, Video, contacts etc.... or will wipe out my complete phone including OS files??

Wow nice. Now to test this on T-Mobile!! Let the flashing commence
Don't think this is a good idea; from what has been communicated the Modem for T-Mobile is different or has a different signature; you might end up with a brick. We we obviously won't find out unless we try. The problem is... you don't have an image to re-flash the T-Mobile version, so you might have to send it in.
im tempted to run this today on the tmobile model. how high is the risk of hard brick? will it leave me without fastboot if it doesnt work?

Yep, if a Dev can chime in that I won't be left with a hard brick and will be able to go back to TMobile firm atleastsr I'll jump. The only thing holding me back is that sim unlock and unlock bin. I don't wanna go thru that again if have to exchange.

It's not how this tool works. A raw dump doesn't equal a flashable fastboot dump doesn't equal a msmdownloadtool ops file.
Edit: apparently you can't use the not equals symbol. I wrote a lengthy reply and it's gone. I'll write a shorter version.
My assumption is there is no version for the T-Mobile, but this will work for a full conversion. OP support will most likely not use this on the T-Mobile version and it's why we had to void our warranty when we unlocked the bootloader. They probably defer you to T-Mobile if you brick your phone. Now that being said, I bet this tool works just fine on the T-Mobile version and will turn it into a full international device capable of OTA updates and everything.

One of three things will happen.
One, it will recognize it as the wrong device and won't flash at all.
Two, it will flash and you'll have a hard brick.
Three, it will flash and you'll have a fully converted International version.
If you have to return it to TMobile, you shouldn't have any issues returning it. A dead device is a dead device, the reps don't care. Also getting your new one unlocked should be no issue as all since you already had your first device unlocked. Just tell support that. Your device was unlocked and you had to RMA it. They will SIM unlock no problem. You will still have to wait 7 days for the unlock bin.

Since this will flash criticals, very likely, don't worry, my download is almost complete, I'll test it since my 6T is my spare device.

it fails, they do have a signature difference after all, I'm thinking we have to flash criticals/persist before this would work...maybe.

Is There Any Way To Remove "Orange State Your Dev.." Message?

Hi guys I unlocked my bootloader etc and like everyone else who owns a E4 Plus I get the message "Orange state your device has been unlocked bla blah"
I was wondering is there anyway to remove/hide it? I already searched the forum and most answers were a "no".
But I just wanted to double clarify hence I started this thread.. I know the message only shows up on bootup but like everyone else I would prefer it not to be there..
any replies would be appreciated thanks.
My model is XT1771 Nicklaus
Cheers.
I flashed a bootlogo that covered it. There are several around, pick what you like.

That just apply for the Qualcomm variants, on nicklaus that warning is reported by lk partition on mtk devices, and cant be removed by just changing an custom logo

It cant be removed, at least that you hex patch the lk partition of the device, this message is reported by this partition, it doesn't load an image on boot, it just display this annoying message, and that its why it xant be removed

I just got this phone for christmas, There are way too many versions of this phone, so confusion is going be a learning curve, what works on one version doesn't work on another.
So far that's the only downside I have found so far with this phone. Mine is the retail version, xt1775.
