Lets Turn That Paper Weight Back to an S8...plus

[droseofc]

This is for those of you that have a S8+ that only boots into Upload Mode and nothing else. When you connect it to the computer it may should say Qualcomm HS-USB QDLoader 9008. Others may have even told you theres nothing that can be done to fix it and that its bricked! Yes, yes, I believed too. I sent to Samsung who sent back the phone and a 850$ option for replacing the board.


I work at Northrop Grumman, they make B2s and stuff, and they happen to have a partnership with Qualcomm so I set up an account with them, downloaded official and latest QPST, QXDM, and QUD. I was able to provision the device using QFIL (unsure if required), but I was unable to flash anything with QFIL. My phone has been useless for 3 months now. I randomly try again here and there, with repeated failure and lost hope. UNTIL TODAY.


Craziest thing ever, and trust me, I know, it does not look remotely close to legit. IT IS.
basically, you do the captcha thing, it takes you to a MEGA download site, you download a zip folder that is named G955U2. Connect the phone to the computer while the screen is black and not on upload mode. The device manager should show the QDLoader 9008 in the Port section. Unzip the downloaded file. Open the folder. DOUBLE CLICK G955U2_Recovery.Bat. Do not run as admin, mine didn't work that way, only double clicking. Wait about a minute, when it says finished, boot the phone into Download mode by holding vol down + Bixby+Power. Not done yet though. SO you should have Download Mode on. Now you need to flash the Odin files, which I am currently doing myself. I have noticed a few issues but I have gotten almost there. I can only suggest flashing a BL first of your firmware and then after that's done do the AP. Once that is done you will be where I am at, and I will update once I am able to fully flash a complete firmware.




Downloads Mod edits am not sure who created that tool, where it came from, or who to thank. Alls I know is it works and is a freakin masterpiece.


Update: I have my phone up and running. On official Oreo firmware I am unable to get any network signals (wireless or mobile). On PartyCyborgRom I am able to get wifi but anytime I put a SIM card in it tells me to reboot, and does the same thing upon boot. I believe that my EFS folder is corrupt/formatted/missing. I have read that formatting the EFS folder to EXT4 can help and that it is mmcblk0p* with the * being a number. The EFS thing is the only issue I am having though. If TWRP were able to be installed on the S8+ for Sprint I would install it and format the folder through it but with the bootloader locked I am not sure its possible. Possibly thinking about completely resetting the phone back to the QDLoader and starting from complete scratch and seeing if I can format the EFS folder before flashing a firmware. Anyone know how to fix the EFS thing?

After flashing first the BL and then the AP separately I was able to flash AP+CP+CSC+BL all at once. I have now fully booted. At first, it will go into recovery and then say failed due to something about mounting an efl folder or something. What I did was mount the system and then factory reset. Then rebooted to phone, and voila. I am not sure if wifi is working just yet or what else may not work. I do know I have booted and am further than I have been before and should be much easier to fix now. I'll keep updated.

Would've been better if you posted the Mega link instead of having to jump through hoops.

I didn't want to overstep the original poster/possibly creator feet. I figured if they wanted the captcha then they should get the captcha because I would've never found it directly to the mega link, nor would have you.

there are adb codes to zero it out i just went through a corupted efs but had a backup i made in Flashfire a while back

 

[TheMadScientist]

@elliwigy might be able to help on this to as I know he has done some edl stuff

 

[elliwigy]

i can tell you one thing you should NOT do is mess with your efs partition.. itstores lots of information such as imei information which you shouldnt "wipe" unless you have backups and a way to restore it

try flashing a full combination firmware then back to full rom..

try flashing cp and csc files from stock firmware etc

9008 mode is EDL mode. those files are nothing new, in fact i havethe same exact files and more.. if u dont know what youre doing i wouldnt use edl more than u have to as you can do moredamagethan harm and maybe harm even edl cant recover from (yes, i bricked a hard brick in edl and had to replace the whole device)

These files are what got me out of a brick. I was in EDL from flashing a bootloader with Flashfire. Could not get the device to do anything but get into upload mode or the qdloader mode. That's what these files were for, for those who could not get out of the QDLoader thing. And I tried everything from Combo Factory Binary to qualfast, flash image loader, snapdragon flash tool, qcomm, heimdall, qcom, efs professional, DFU, DFS, Samsung PST SW DLL, CDMA Workshop, CHMC PST, Gtran, PSTlite, CDMA universal, VK Mobile, Symbian Flashing Tool, QFIL, QPST, emmc. Nothing got me out of the EDL except that link. And it was just as simple as two clicks.


As for the EFS folder, I was able to reformat the EFS so that in recovery it no longer said "unable to mount /efs" and I could do a factory reset without any mount warnings. I tried restoring a backup of another s8+, doing the erase everything but two folders in the EFS folder and flashing a combo in the AP slot and then a official firmware, nothing was able to bring back an IMEI as it displayed all 0s. There may be a way, I tried programming the IMEI with various tools. I ended up talking to sprint to have them attempt to reactivate the device on my account, while doing that I added TEP (protection plan), in the midst of trying to activate they became aware that I had 0s for my IMEI and advised I take it into a store. I did just that and it would of been a free replacement but I had a teeny unrelated smidge of a crack on the top right corner so I have to pay 140$ for a replacement/repair. I'm sure it'll be a replacement because as you said, without a backup of the EFS its pretty tough to get it back.

 

[elliwigy]

if u read my post i said i wouldnt use edl more than u have to if u dont kno wat ur doing.. if ur stuck in edl mode then u had no other choice..

that is what edl mode is used for, to recover from bricks..

however, u clearly wiped ur efs in the process andtheres no way to recover that so not sure y ur still trying to wipe it or recover it lol.. theresno way to recover efs if u never backed it up in the first place.. flashing random files will not magically repopulate it unfortunately

OP edited pay per click links not allowed

 

[Linkzz]

will this method work on Binary 5 firmware?

 

[sunilgeorge]

Can you please let me know what the fix is for this? I have an S8 like this.

 

[Amslow]

I suggest you go thru the post and read from begining, thoroughly... its elaborate enough, ive not tried but i'm going thru it for knowledge sake
