I'm guessing your not using LGUP since your seeing that error? If your running MM you must use LGUP

Hey guys, I have a LG D851 and the phone is boot looping (stuck on the T-Mobile splash screen). I tried the KDZ method using the D85120E firmware. The phone is currently on D85120G firmware. For some reason, during the flash process, it gets stuck at 10%. Has anyone experienced this issue before? BTW, I using a WIN10 x64bit. and the phone is properly recognized by my computer.

Thanks
Mike

This is for LG G3 D851 ONLY
TOT/KDZ/TWRP Untouched stock restore​



Who can benefit from this?
  • Anyone who softbricked with access to download mode [KDZ RECOMMENDED]
  • Anyone who wants to use the OTA function after root [TWRP RECOMMENDED]
  • Anyone who needs to send the phone in for repair [TOT RECOMMENDED]
  • Anyone who wants to be on the most recent firmware [TWRP RECOMMENDED]
  • Anyone who wants to downgrade *After you update to 20B it is recommended to not downgrade. If you do you WILL have connection problems
  • Anyone who wants to return to stock from aosp or aokp
    • Tip: Most of the time TWRP will do what you need without the troubles and baggage TOT and KDZ bring. It will downgrade, upgrade, root, fix soft bricks or just give you a fresh untouched operating system (no personal data left on the phone if you follow instructions). It will also get rid of any proof on the phone that you were rooted (my t-mobile reports root to a remote server nothing can be done about that).

Strengthens and weaknesses for each method click here

TWRP Files/flashing guide Most recent = D85120E
(This is a WIP)
  1. Download your preferred choice of D851xxx-Untouched_Stock_Restore.zip HERE (Perfect 1:1 image unlike most roms)
  2. Copy D851xxx-Untouched_Stock_Restore.zip to phone (external sd if available)
  3. Reboot into twrp
    • For firmware update do not wipe! skip to step 8. If you want untouched stock continue with step 4.
      If upgrading from kitkat to lollipop wipe system before flashing.
  4. Click [Wipe]
  5. Click [Advanced Wipe] (For full wipe stock restore only)
  6. Select dalvik cache, system, Data, Internal storage (only if you use external for downloaded file) and cache
  7. Click the home Icon in the bottom left
  8. Click [Install]
  9. Select D851xxx-Untouched_Stock_Restore.zip (make sure you select the proper sd card)
    • If you want root and/or twrp add UPDATE-SuperSU-v2.37.zip to the queue by touching [Add More Zips]
      Repeat for TWRP-2.8.6.0-d851.zip
  10. Swipe to install [====>]
  11. Install will now begin, pure stock: system, kernel, recovery, modem and rpm will be installed
  12. After completion click [wipe cache/dalvik] (do not skip especially if you dirty flashed)
  13. Swipe to wipe [====>]
  14. Click [back]
  15. Click [reboot system] (it might say no os but it is wrong you do have a os click restart anyway) [dirty flash will not have that problem]
  16. If your sending for repair or jump do a factory reset with what should now be the stock recovery just to be safe.
DO NOT INSTALL ROOT UNLESS YOU WANT IT TO BE ROOTED


KDZ files/flashing guide (Use TWRP if you can)
(This is a WIP)

Here are the KDZ files for the D851 I will keep this up to date as they are released

Make sure you uncompress the file!

Most recent Firmware
D85120E_00 (6/10/15)

Old Firmware

D85120B_00 (3/31/15)
D85110R_00 (12/2/2014)
D85110M_00 (9/10/2014)
D85110C_00 (7/9/2014)




KDZ FLASHING GUIDE



  1. Download, extract and install LGUnitedMobileDriver
  2. Download, extract and install VBCFJRedist_AIO_x86_x64
  3. Download and extract LG Flashtool 2014.7z (This is not the same flash tool in TOT method)
  4. Download one of the KDZ files from the beginning of the post and extract it in the Flashtool folder
  5. Make sure you are at least at 50% battery
  6. Enter download mode by holding the volume up button + plug the phone into the computer from a powered off state
  7. Run LGFlashTool2014.exe as administrator
  8. select type [CDMA] (Yes CDMA works just fine for our T-Mobile GSM phones DO NOT USE THE OTHER OPTIONS)
  9. phone mode [diag]
  10. reset time [33000]
  11. select the KDZ file you extracted from inside the flashtool folder (D851xxx_00.kdz)
  12. select [normal flash] (no wipe) or [CSE flash] (wipe) (Recommended)
  13. click [start]
  14. Select Country and Language Just leave default selections and click OK (Republic of Korea is the only country and it defaults to English)
It will analyze the phone extract the firmware and upgrade your phone automatically you will see progress on both the computer and phones display once the s/w upgrade percentage gets to about 80% your phone will restart don't freak out all went well and it will boot up to the LG welcome screen and if you selected CSE it will restart one last time

Total flash time for me was 2 minuets 56 seconds

If you use the normal flash you might need to do a factory reset if you get in a bootloop after flash
cse should have 0 problems on boot

If you have problems just ask and myself or somebody else will be able to help.

Can i use this to downgrade my phone

I have a D851. The history of flashes is very long, but I ended with the 30D firmware except the TWRP recovery. Lately I moved to Fulmics. Every time I flashed Fulmics I had to flash the 30D modem. The problem came when I flashed the N&N rom. It bricked the LG G3 D851.

The situation now is that I cant enter into recovery mode but can enter into fastboot mode by pressing vol+ while plugging the phone to the computer. The problem, I can't flash anything. I tried KDZ and TOT methods, adb and even mfastboot. No luck on this. The screen is the typical Firmware Upgrade, showing 633A B54 in the log window at the bottom. Very similar to issue described by muchepicfail in post #735.

I am still interested on some files in the internal SD so I do not want to follow the definitive unbrick guide for the LG G3 yet. At least I can still access the fastboot mode so I would like to thing I still have hope.

Any ideas? Thanks

Does using the KDZ in the OP restore stock recovery as well? For example, does it remove TWRP if you had it installed?

Fastbot mode was broken, I wasn't able to flash kdz or tot files. The only way to recover my d851 was to open the phone and put the usb in qualcomm 9008 communication mode. I inserted the partitions and recovered the phone. I still do not know what happened with the N&N for my d851. It caused the brick but I do not know why. The zip file was fine.

Does anyone tried this in a d851? Did you upgraded to 30D firmware before?

Thanks

If you have a "full brick" you cannot fix that that's what full brick means. The whole term brick should really be clarified. Soft brick = fixable. Hard brick = is a forever paperweight. You'll need to follow the unbrick a soft brick guide in the general section which involves taking apart your device and hope flashing wrong model firmware didn't wipe your EFS.

D85130e KDZ and TOT not working

Hi everyone, I have an LG G3 D851 running on D85130e. I want to downgrade since wifi is not working. I tried the KDZ and TOT and neither worked.

For KDZ when I get to the last step and the software on my computer tries to push firmware it stops working and tells me to retry and COM4 never appear on my phone screen and my phone stays at 0%.

For TOT I went to step 18 and connected my device then it gave me an error with something like unable to connec. (I did change to COM41)

Does anyone know what could the issue be? Is there another way to flashback my device?

Thank you very much.

how did you do it? the KDZ method gets stuck at 4% and the TOT method fails with error "Model Information Check Fail!"
no matter which dll i try.
-----Edit----
using the D85130d_00_0404.kdz file worked fine.

Hi, I think I'm having a similar issue as you.

Where did you find the D85130d_00_0404.kdz file? Did it end up working with TOT or KDZ, and if it was TOT what dll did you use?

If your not using LGUP that is why. If you running MM you can only use LGUP to flash firmwares.

I'm confused by your last question. It's a .kdz file so it's a kdz file not a tot file.

Thank you very much for the help, it's been very frustrating because Wifi is not working on my phone. I will try using LGUP and see what happens. I found a couple of websites with instructions on using LGUP, is there a specific guide you would recommend?

Again thank you very much.

There's no specific guide as they're all pretty much the same. I have a guide in the General section for the G3.

    So use this method to flash back to stock?
    Click to expand...
    Click to collapse

    Correct it also gives developers a chance to start making stock roms even though we don't have root or a recovery yet.

    Added:
    D85120B flashable zip (Lollipop)
    and
    TWRP installer zip

    *Important information Below*

    • Wipe everything except internal and external data for the best lollipop experience. But if you must dirty flash you MUST wipe cache/dalvik and system or you WILL bootloop. You could skip wiping system but problems might happen.
    • If you did dirty flash it might take a long time to get to and from the T-Mobile screen. If it takes longer than 5 minutes to get past the T-Mobile screen pull the battery wait 10 seconds and power it back on then it should bring you to the updating android screen, give it time.
    • After a reboot update your apps ASAP
    • If you downgrade from lollipop your phone will need to reboot several times before it recognizes your sim card. You will also need to format system before downgrading. If you downgrade with twrp you need to format system before flashing.
