SDCARD BOOT? help me understand.... - Samsung Galaxy S20 / S20+ / S20 Ultra Questions &

Hey guys, so i own a galaxy s20+ SM-G986U BL LOCKED and i was curious, if we can tell the hardware to boot from sdcard couldnt we burn an image with root to the sdcard and just not use the eMMc memory on the board??

Wow very good question, honestly it doesn´t sound to easy.

That would be wonderful if possible, and then use the eMMC as SWAP.

Yeah, that'd be ideal! I already took apart an A21 SM-S205DL and am researching to see if there's any similar chipset this has been achieved on..

That's amazing! Heck yes. I was thinking about this for my Sprint Galaxy S3... so not quite on the same level, haha.
Most of my devices are elderly ones I want to breathe fresh life into!
The last SD-card-booting phone I had I think was the HTC HD2!!!!

Yeah I'll bet there a switch on the motherboards. From my research this has already been exploited in the past on even newer models than the S3, you should look further into it, let us know what you find!

You will need some files to flash the bootloader of the device to let it possible, Just like HTC hd2, but need great dev work

what files do you think i would need? firmware stuff?? binary data?? im really new to development at all, im going to school but id really like to hack this one...
also, do you think id have to get my hands on some firsthand knowledge? like how the motherboards are put together, which pins to reroute??

nope sorry, it is just A theory, i will try ask mods about this

So I haven't been able to find much relative documentation on the exynos chipset. Am going to start looking into snapdragon considering my s20 is a snapdragon model. My test subject is a exynos... I took some photos of what I believe may be relative pins and will attach the files on this post. Any input would be greatly appreciated! Sometimes, old methods and exploits will come back into relevance. This could be a Golden opportunity to skirt Samsung's bull**** BL! Concerning my photograph, this is the side of the board opposite the sim/SD card storage. Don't know what the pins are for. Let me know!!

maybe someone can have A file to flash A BIOS-look BL like HTC HD2 had done?

Bookmarked that! Thank you for the link!
These guys were working on devices that already have bl unlocked even before they start to think about booting solely from micro SD. I'm working on a s20 model that's infamous for having a LOCKED bl. My main objective is to modify the motherboard to detect the SD CARD in place of eMMc. I'd like to see one of these have root without any firmware upgrade or flashing NAND, just like having a second SSD for a laptop. Just swap it out.

Can a t-mobile tp2 flashed with a cdma rom be brought back to a gsm radio rom?

Hi. Can a T-mobile HTC TOUCH PRO2 (US version) which was stupidly flashed with a SPRINT CDMA ROM be brought back to GSM by reflashing it with a GSM flash ROM file using a PC running Windows? If so, where can I obtain the flash ROM file from, as well as the utility to flashing it back with.
PS: HTC Techs wouldn't help me except telling me to send it in so they can charge me more than I already paid for this phone already. Thanks in advance for helping or trying to help.

Well, my "know-it-all" buddy who's had great success with tinkering & flashing my other phones, B-R-I-C-K-E-D this one. Now he and I have been through the gamut on trying to reset this TP2 with the problems listed in another thread here using forum members' suggestions as well as the resetting tips for this model found on HTC.com with no success. So I had a thought in my sleep. Maybe, just maybe, I can reflash it?
Symptoms: There is no screen on this phone now. My PC tries to recognize it for about 1 minute or two, after it displays it's hardware signature in Device Manager 2-3 minutes showing up as "Qualcomm CDMA Technologies MSM" with an exclamation point under "Other Devices", then, the phone's hardware signature disappears from my hardware list in Windows 7's Device Manager listing. It didn't do that before.
"My Other thread" referring to all I did in trying to revive this phone with the help of other members here.

You should be able to connect the USB, go into bootloader mode, and then run update the ROM. You should probably run task29 first to clear the memory. If you can't get the USB to work, you can flash from your SD card. Check the first several posts of the ROM forum, rather than this GENERAL forum.
find an official T-mobile HTC TOUCH PRO2 rom and flash it.
and if your device has hard-spl then you can flash any full gsm rom.

Nope no good. These tips all expect some sort of interactivity between the use & the phone present like being able to go into bootloader mode or expecting something visual on the screen. My TP2 doesn't do anything after flashing it with the CDMA process (provided by the Rhodium.htc-unlocks.com website), except turn on the little orange LED ever couple of minutes until the battery just dies out.
You now have a nice paper weight or brick. Flashing a cdma radio and/or bootloader/unlocker is NOT reversible. If you had only flashed a cdma rom then that could have been reversed.

If you cant get into bootloader I'm almost certain that means the phone's bricked. I realize that's likely not the information you want to here but you need at least a FEW things working on the thing to be able to flash it to a different rom. Bootloader being one of them.
If you cant get into bootloader mode,then i dont currently know any other way of reviving the device at home.sorry.

RMA usually it's totally free you only have to pay to send in the phone. I know cause I did the same thing kind of... I flashed a GSM rom on a CDMA phone and totally bricked it. My phone connection led didn't light up when connected. Then I call HTC, they sent me to call another company that handles US Cellular and got it RMA paid only shipping.
If your led connection lights up there might be a possibility you can flash your stock rom with a clean Micro SD Card. Just search for this method on the forums, it has been a working life saver to many.

The only thing that might work is to go back over the the CDMA forum and find out how the CDMA version invokes the bootloader. Maybe it is different than the GSM version? If you can't get to bootloader you are in trouble.

Bear in mind that (I believe) the OP said he Hard-SPL'd the device. I've seen numerous tales on here, of HTC declining to repair under warranty in those cases, citing 'Illegal software'. They usually then quote a couple of hundred dollars to change the motherboard, or a fee to return the phone unrepaired (the fee is their charge for the diagnostics).
I have the same error. Any new guess? In my country there aren't HTC repair stores
hi all:
anyone here know how to reboot the tmobile tp2 after I think I brick it? probably flash with wrong rom. now the phone will not turn off. stuck at "stick together".

[Q] A few questions related to Hard Brick and QHSUSB_DLOAD

I am now owner of what may very well be a Hard Bricked Samsung Galaxy S3 with the inability to reach Download Mode and computer not recognizing my handheld. It ll happen't as I unlocked my bootloader to go in fastboot mode, it was then, all over. But of course as desperate as it may look like I've done some researches on Google and some people with different models managed to have some magic done in a situation like mine, but since I didn't own the same device the solutions were of no avail for me. So my question is, is there any sort of trickery to help me come out of this misery? Such as force installing new QHSUSB_DLOAD specifically for a Samsung Galaxy S3 or some battery related magic that could help me reach Download Mode where I could flash a stock rom back in and get back to normal? Any help would be much appreciated.
this just happened to me as well today, not to happy, my heart sank in, did u find any solutions as far as fixing this qhusb thing?
AFAIK there is no fix, same deal on all phones with the same SoC, like the one x. I could be way wrong though and I hope I am. Hope you guys get up and running soon.

Most likely they will say that you voided your warranty so you may have to take it in to a JTAG service.

Any update on this? My phone did this to me last night when updating CWM. I'm about to go to Radio Shack to buy some resisters to see if I can force download mode, like on Captivates.
EDIT: Even though this video (http://www.youtube.com/watch?v=TrZUrE5Nqj0) shows that the Jig works with the GS3, I was not successful in putting it into download mode. I was able to with my captivate, just to make sure I was on the correct pins.
Hopefully the AT&T store will just swap it out and leave it at that, since I pay for insurance...I don't want to have to send it away to mobiletechvideos.com for JTAG repair, but will if necessary.

Regardless of where the phone came from the end result is still the same... you guys are hard bricked. The only available solutions to you atm (and trust me on this I hard bricked mine aswell) is
A - Send your phone in for warrenty/insurance, dont worry about everyone saying you cant because of voided warrenty... your bootloader is screwed and they wouldnt be able to tell anything about rooting/cwm etc.
B - if warrenty/insurance is unavailable to you then your only other options are to send it to samsung to get it repaired on your own dime. Or save yourself a bit of money and send it for jtag repair which is what I did. If you live in the states the guy can have your phone back in your hands usually within 4-5 business days.
hi there

is there any software so i can make image and share...to help those who hard-bricked their phones.

I reject your reality, and substitute my own! Ah, anyway.. any updates on this? Its been a year or so.. I have the sprint s3, but i believe it had an insecure boot image flashed to it. The emmc boot method has failed me thus far. Not sure if it's because mine is a 32gb and the debrick files for for 16gb '(which shouldn't matter), if the board for my 32gb is affected by a brick bug, or what.. The qpst tool just seems like it's the perfect tool to fix a bad bootloader on any qualcomm phone, but all the guides I've found are for other phones still. I accidentally dd'd an image of my EFS partition to the sbl2 partition. I looked up the international s3 table by mistake

Yes. Download a live linux distro, like knopix or such. Any linux distribution will work, really. Then in a terminal you would do something like
Code:
sudo dd if=/dev/sdX of=debrick-image.img
Where the "X" in "sdX" corresponds to the sdcard you want to copy. After you insert the card, in a terminal do:
Code:
dmesg | tail
and you should be able to see that it is sdb, sdc, sdd, etc. Google the usage of "dd" if you need more info.
Thanks for info i'll try this today

Damn...just made a huge mistake. phone bricked?

My son wanted to root his brand new phone. i have rooted 8 phones from different phones before with success..... but this time i f***d up...
Accedently installed this on his phone.
http://wccftech.com/flash-and-root-nexus-5-on-android-6-0-1-mmb29k/
executed flash-all.bat and it flashed the bootloader.
For the wrong phone...
It should have been this one..
http://wccftech.com/flash-and-root-nexus-5x-android-6-0-1/
Missed the X......
Now the phone will not even boot any more at all....cant enter bootloader.......does not power up at all.!!!
Jesus...what have i done.......
It here any chance at all to fix this somehow?
Hello and thank you for using Q/A,
because you can't enter bootloader, you can't do anything. You can try to send the phone to Google. Say: It didn't boot after OTA Update.
Kind regards

Yeah it's most likely a paperweight. Try sending it to Google. Flashing the wrong firmware destroys a phone as you probably already know

Your use of the period seems rather condescending. And no, you as the end user cannot fix that. You did one of the few things that is unrecoverable unless you manage to get the bootloader to accept adb commands somehow.

Well. the bootloader is flashed into the phone from the beginning aswell during manufacturing. I work with electronics and software and i know there is always a way to reflash the bootloader. All the electronics comes in the beginning with no software at all, one only needs the proper software/hardware. Most probably by jtag....or if they have some other special tool for snapdragon 808.
Stupid of me not to see that the version i flashed was not for nexus 5X...and only for nexus 5

Good luck. Will Google not rma it?

Are Qualcomm TrustZone keymaster keys the path to our unlocked bootloaders?

It seems we are getting the keymaster keys very soon:
https://twitter.com/laginimaineb/status/737051964857561093
Could this mean we all get to unlock our bootloaders?
And more importantly, can we lock our bootloaders? I've got the H815, European model, so I can unlock my bootloader, but then it's stuck unlocked. Bam! Warranty gone.
Can someone briefly explain the end-user aspect of this to me please? Does this mean we'll eventually be able to unlock Qualcomm bootloaders and/or boot unsigned images on the Verizon G4? If so, any idea if it's dependent on a MM or KK base or should work on any version?

What I DO know is that if you encrypt your device. The device can now be decrypted in the hands of a hacker or anyone else for that matter with the relevant skillset.
The only real roadblock is the passcode on your phone if there is one set. And at that point, brute force (aka trying til you get it right) will get the job done.
As for the bootloader. I'm not too educated in Android (Took level 1 Android at school, didn't like it) but it looks like it might have some potential in helping us out. But I'll let one of the devs make that call. Feels too good to be true.
If it can decrypt 64 bit sys like it claims very well could be possible.

Sounds like a good news. I don't have phone encrypted, so no bad news for me.
by this point G4 is over a year old
even if this was a viable option of unlocking the bootloader, I doubt many would be interested in it and that it would suddenly bring ROM developers to the G4..
LG blew it with G4 (regarding the bootloader unlock), the damage has been done and most of the relevant people moved on

All i know at this point that most of the boot partitions are encrypted with a 256 bit key which would take some of the strongest computers in the world a long time to brute force thats why i think this script prob wont work but i dont know until i try it. Its kinda like tryin to hack the password on a zip file but worse. Ive spent weeks trying to brute force zips so thats why i got my doubts

Thanx man i aint no one special. Im just puttin in my best i aint in it for no bounty or nothin i just want a device that works rite. Just hopin is all. Ive been in this for a while.

Im trying to find one of the scripts that extract the keys i cant find one. Most of the comments lean towards it being able to decrypt any qualcom chiped device from what it sou ds

The guy hasn't released the script yet so that may be why.

So what exactly does this mean for us assuming the script is released? Will we be able to pull our encryption keys and therefore unlock the bootloader (assuming any necessary changes are made), or am I misinterpreting all of this? Also, it appears that he did this with phones containing the Snapdragon 805 SoCs, does that have any bearings on us seeing as ours is an 808 SoC, or is it not bound by the SoC? Sorry for the newbish questions. Not really well versed in the inner workings and creations/implementations of hacking/exploits/etc.

thats about it were just hopin it will unencrypt the bootloader then from there a unlock should be a lot easier
"@laginimaineb And wrote a script to decrypt all keystore keys. This can also be used to bruteforce the FDE passphrase off the device! (2/2)"

Brick prevention galaxy note 20 Ultra model galaxy SM-N960U

Im trying to root the phone and install some brick prevention. I used helium backup already, is that enough?
And is it possible to turn on oem unlocking yet on the US models?
Also fastboot wont work.
No such thing as fastboot on Samsung phones.
There's plenty of information in these Note20 Ultra forums on the ins & outs of rooting, use the search function to locate the appropriate threads.......
A $1G paper weight.
Why do you want to root it?
These phones can run well, stock.
If it seems like a bad idea, it probably is.

What a smug response. I'm loving this phone, I just want Linux on it and don't want to turn it into a $1000 paperweight.
And I also just want to know if helium is enough to prevent a brick.

Android is a modified Linux kernel.
There's always risk to rooting especially if you are inexperienced.

I don't think enough people use it to get an honest reply, aren't these features that Titanium Backup can do?
Don't try my friend
US devices cannot be rooted because they come with a locked bootloader from the source

You are misinformed. 9 series to nearly current anything one ui 3.0 and lower can be bootloader unlocked and rooted.
Nothing is enough to prevent a brick. There is no oem unlock. No fast boot.
