Yesterday, I installed winrar on my wife's computer and tried to un rar Patched LGUP. I kept getting an error message that read "mfc100dll". I re-downloaded the link several times thinking it might be a bad download. But, apparently, it's not the download, but something with the computer itself?

Anyone encounter this error message before and have a fix for it? The computer is a tablet with a removable key board, Microsoft Surface Pro 3. I have to tread softly because my wife has several important files on it, and is really fighting me on messing with her computer and my phone (doesn't want me to hack it).

Any help with a repair would be much appreciated.

Thnx

Hey Matt, while using his method to get through the process of rooting my VS996, when I get into download mode and open LGUP, it doesn't recognize the device and won't go any farther saying its an Unknown model. any suggestions?
[LG V30 Guides, News, & Discussion] ChazzMatt:
I'll give you all my previous answers, all of which have worked. I just don't know which one will work for you.

Make sure you in download mode BEFORE opening the patched LGUP file.

This is at the top of the list as some people forget to do that. The remainder are in no particular order. If that doesn't work,

Try different USB port,

Try different USB cable,

Try different computer.

Reinstall LG mobile drivers.

Reinstall dev patched LGUP again, making sure the files are placed where they need to go (LG Electronics folder, etc).

Reboot the computer.
[LG V30 Guides, News, & Discussion] edle.sieben:
So I'm relatively new to roooting LG, and I went and downloaded LGUP from the first source I found and ran it... didn't contain any folders or manual install... is there a newer version I should be using?

Sorry for my newbie-ness

Bricked my phone!

I somehow managed to mess up. Have an H933. Downloaded the US998 Nougat KDZ file. Installed the patched LGUP version (placed the files in C:\Program Files (x86)\LG Electronics\LGUP). Entered the download mode on my phone, opened LGUP, ticked the DL Partition option, selected the KDZ file and clicked on Start. After that I got a pop-up window where I clicked "Select All"

Next, I got a warning saying some of the partitions would be modified. I guess I should've known something was wrong at that point, as nobody seems to have gotten such a warning (?)

I just clicked ok after which the KDZ file was flashed onto my phone. Flashing went fine I suppose. The phone auto-rebooted at the end of it. But, after the LG logo, the phone entered the download mode but the screen kept flashing on and off. LGUP couldn't recognize my phone any longer. I disconnected my phone, tried rebooting. The only combination that worked was VolDown+Power. That took me to the Recovery screen, but again the screen flashed on and off and I could see the message "No command selected" under the android bot image for a fraction of a second before the screen flashed off again.

Now, I can only restart my phone by pressing VolDown and Power, and the screen keeps flashing on and off in the Recovery (as I mentioned above). So, basically, no fastboot, no download mode, phone's not recognized as even a Qualcomm device when I connect it to a PC. In short, it's completely dead.

I'm still wondering how this happened!
[LG V30 Guides, News, & Discussion] ChazzMatt:
I don't see anything drastically wrong.

Sounds like you didn't do the Master Reset yet. You are at the "unstable" stage after first flashing Nougat. You need to follow the rest of the instructions.

master reset using buttons:

1. Press and hold the Power and Volume down buttons.

2. When the LG logo appears and quickly release the Power button only and press Power button again but keep pressing the Volume down button until you see the screen to select Yes to erase and reset everything

[LG V30 Guides, News, & Discussion] Sudhanshu90:
Yes, it worked! I'd read one of your posts where you'd spoken about the need to master reset else the phone being unstable and all, but, I never thought unstable could mean near dead :D :p

And I'd tried the sequence earlier, I guess I hadn't pressed the volume down button long enough.

Thanks a ton man! I was contemplating going the JTAG route! You saved me :D
[LG V30 Guides, News, & Discussion] ChazzMatt:
Now you can move on to the Oreo stage. Since you have the H933, you'll need to use DL PARTITION method yet again.

Dual Sims

I bought LS998 from ebay and will convert it to US998. But I also need dual simcards. Is there a way to get dual simcards? Maybe by replacing the simcard tray and flashing H930DS firmware?

Thanks.
[LG V30 Guides, News, & Discussion] ChazzMatt:
This is where you meant to post. Argue here:

The other thread is about bootloader unlock and root and what you are talking about is not relevant there whatsoever.
[LG V30 Guides, News, & Discussion] jcsww:
I don't consider a disagreement an argument. If gou want to continue the discussion here. That's fine with me, even though the question was asked in the other thread.
[LG V30 Guides, News, & Discussion] ChazzMatt:
These are the facts your are trying to argue against:

The person who created this thread, the op, made that statement.

And we are NOT going to discuss changing IMEI on XDA.

But again, you don't need OTA as you will have access to superior KDZ updates.

If you have proof to the contrary for an LGUP converted US998, feel free to present it. Not original US998, but converted one that was originally another V30 variant.
[LG V30 Guides, News, & Discussion] jcsww:
That makes absolutely zero sense! How did theybcome to that conclusion? It sounds like they are confusing OTA's with unlocking the bootloader via LG's developer portal. There is no IMEI check for installing OTA's.
[LG V30 Guides, News, & Discussion] ChazzMatt:
No, this thread was started well before the BOOTLOADER Unlock and Root exploit was discovered. It was only about converting to carrier unlocked model, like AS998, US998, or even H933.

That specific answer (May 10) was DAYS before the BOOTLOADER Unlock and Root thread was even created (May14), and has nothing to do with bootloader unlock and root. It's about updating a converted phone.

You won't RECEIVE OTA updates, probably? BUT you can use superior KDZ to update on US998.

My problem was I didn't put the patched file in lg up directory
[LG V30 Guides, News, & Discussion] ChazzMatt:
Yes, you can brick your phone. We are still finding out which phones can be successfully cross flashed using this Partition DL method. It's a more advanced "dev" option in the patched LGUP. You are only cross flashing PART of the firmware, not all of it. Still not all phones are eligible for this.

But the fact it can be done at all is a surprise as we were told this wasn't possible anymore.

We first saw it a couple of months ago with a "Canadian" H933 V30+ -- which doesn't exist in real life. (There are no H933 V30+, only V30.) We didn't know what it was. I speculated someone had physically swapped hardware parts out and back panel and "created" this Frankenstein phone, while retaining the H933 firmware.

Now in retrospect, it's simply a "bad" Sprint V30+ LS998 converted to "H933". :rolleyes: (Tons of bad Sprint phones on eBay.) We didn't know this was possible, was actually told it was impossible.

Since then, we've seen Sprint and Verizon phones converted to US998 and AS998. And vice versa. Impatient US998 owners (both open market and U.S. Cellular) have flashed Verizon's Oreo KDZ and turned their phones into "VS996" V30. Most of these are Verizon users who are happy to find their Verizon voice mail works now, since it didn't with US998.

When you cross flash, this also affects radio bands -- for good or bad. One person is happy to find out that cross flashing H930DS with H930 open market Oreo KDZ now gives him more AT&T bands. But the opposite could happen.
[LG V30 Guides, News, & Discussion] Moriatier:
it does not work. LG double checks your IMEI and device id for bootloader unlock, the latter being unable to alter no matter what you did to your phone.
[LG V30 Guides, News, & Discussion] ChazzMatt:
I'll answer what I can of your questions. No, I've not tried my LG supplied unlock.bin for my open market LG V30 US998 on my open market LG V30+, because of all the information LG requested before sending me the file. Not only IMEI (which can be faked as you mention) but also Device ID (a 64-character alphanumeric string for which you need physical access to generate). If both those were checked and matched, then LG sends you the unlock.bin file.

The unlock.bin file itself is just 1KB in size. In notepad, it's just a bunch of hieroglyphics. I assume it's some kind of encrypted unlock code.

I assume it's customized for your specific device. I would also assume at least some of the open market US998 owners here on XDA have coding skills I do not and have looked at their own unlock.bin files. If this was something that could be hacked, I would think it would be discussed before now.

I know with Motorola phones -- which I have a lot of experience -- people got samples of Motorola bootloader unlock codes, which were just a string of alphanumeric characters. For the Verizon Motorola phones (which were not allowed to get those codes), no one could ever create a code generator. Each bootloader unlock code seemed to be totally random and only worked for that one phone.
[LG V30 Guides, News, & Discussion] jcsww:
If someone could decrypt it, then I was hoping someone could come up with a generator to make the correct string. LG asking for a lot of info makes sense for a couple of reasons. If all of that info goes into the string, then it gets harder to crack. But the other aspect that crossed my mind is that the info just might be their way of making sure they don't slip up in verifying a devices warranty eligibility against it being bootloader unlocked, which voids your warranty.

Thanks, Chazz! I'm just grasping at straws. The cross-flashing though was overlooked originally so I am hoping we are giving LG more credit than they deserve when it comes to locking down their devices. :P
[LG V30 Guides, News, & Discussion] jcsww:
I tried my H933 to an H932. Everything went fine but in the middle, I got some popup about the user data. I clicked, yes. I don't recall specifically what it said but something about the user data had changed. My H933 was on Oreo where the H932 doesn't have Oreo yet. Everything completed successfully, however, the phone remains at a black screen and is no longer recognized. In the Device Manager, it now lists as QUSB_BULK. LU GUp does not recognize the device. Doing a little quick digging, I have seen some previous LG devices pop up in search with this issue and YouTube seems to say it is fixable. I don't know off hand but I also don't have the time to read up on it right now. So... Attempt one on the H933 didn't go well. :P

Obviously, I don't have a driver installed for that mode, if it is actually in that mode. I was reading a little over in the G4 forums about how to unbrick with an SD card. Would something like this be possible (at the link below) with the V30?

https://xdaforums.com/tmobile-g4/general/lg-g4-h811-complete-unbrick-guide-100-t3461629

I really need to head out as I am already late. I hope there is something useful in all of that.
[LG V30 Guides, News, & Discussion] runningnak3d:
[MENTION=3116388]jcsww[/MENTION] 9008 bricks are not fixable on UFS NAND devices by booting from an SD card. The boot path is stored in QFPROM (on the CPU) and it is something like /dev/block/sdb or /dev/block/sde. On eMMC devices, the boot path is /dev/block/mmcblk0. If you have a 9008 brick, the SD card is seen as /dev/block/mmcblk0 so the phone will boot from it on an eMMC device since that IS the boot path. There is no way to make the SD card appear as /dev/block/sdX. And there is no way to change the boot path once you have a 9008 brick without a firehose. If you have a signed firehose, then you can fix your phone without needing an SD card ;)

As for cross flashing. I checked the RSA signature for the H930, H932, H933, and US998 and they are all different. If you flash any of the signed firmware (xbl, abl, hyp, modem, etc) from one of those devices, then you have a 9008 brick and no way to fix it yourself.

I didn't bother checking the Verizon or Sprint models since they are even more locked down than the H932 is, but it appears from reading this thread that they have the same key as the US998 (I am not going to waste my time checking).

[LG V30 Guides, News, & Discussion] ChazzMatt:
Were you using the DL mode of the dev patched LGUP or exactly how did you flash?

Sent via open market LG US998 V30/V30+
[LG V30 Guides, News, & Discussion] jcsww:
Yeah. I used the instructions in the OP, selected the partition DL, selected all, and let it go. Maybe I should have paid more attention to that user data prompt that I clicked yes to. It isn't a big deal though. It will get replaced easily enough. I'd rather mine get messed up than someone else's that would have to send it out and wait for a repair. I was reading after in another thread, that some were having issues going back to N from O. Maybe that contributed to the brick? I'm not sure but it all seemed to go well. :P
[LG V30 Guides, News, & Discussion] Moriatier:
As is mentioned by [MENTION=3167089]runningnak3d[/MENTION], the RSA signature of H932 and H933 are different and if you do a crossflashing it will be highly possible to brick your phone unless you find a way to avoid certain conflict in the partitions.
[LG V30 Guides, News, & Discussion] runningnak3d:
Here is the list of all files that are flashed in a KDZ that are signed with the RSA cert. If just ONE of these doesn't match the key in your CPU, you will probably have a 9008 brick. Some just won't load, and your phone won't work until you flash the proper KDZ (for example modem), but the fact of the matter is -- it is NOT possible to crossflash ANY of these files IF the RSA key in your CPU doesn't match the signature on these files:

ablbak.image
abl.image
apdp.image
cmnlib64bak.image
cmnlib64.image
cmnlibbak.image

devcfgbak.image

pmicbak.image
pmic.image
rpmbak.image
rpm.image
storsecbak.image
storsec.image
tzbak.image
tz.image
xbl2.image
xbl.image

If you have an unlocked bootloader, this is the list of files that you can flash without worrying about the RSA key:

boot.image
recoverybak.image
recovery.image
lafbak.image
laf.image
system.image
userdata.image

If you do not have an unlocked bootloader, and you flash one of the above files WITHOUT flashing the corresponding abl, you will bootloop and never be able to fix your phone. So, if you have a locked bootloader, then you must flash ALL of the partitions listed as being checked by the RSA key, and ALL of the partitions listed here. If you don't -- you will not have a working phone.

And finally, this is the list of files that you can cross flash that aren't checked by the RSA key in the CPU nor dm-verity:

cache.image
carrier.image
drm.image
eksst.image
encrypt.image
eri.image
factory.image
ftm.image

You could use the AS988 Oreo in the Development section. It's basically "US988" for regional carriers.

Just a caveat. You flash at your own risk. All the Asian cell phone guys are doing it. But is there a step we don't know about? Or some prep? That's the problem.

1) it's possible you removed something in ADB which is causing it to fail.
