Good evening, Sir.Because this root method uses a LAF Partition from another North American variant, the Canada H933. But ONLY that one Partition and ONLY if the bootloader is first unlocked. It's the one exception to the ironclad rule not to cross flash any other variant firmware over T-Mobile H932.
Tried that and will not work. This particular model HAS to be rooted in order to be carrier unlocked. This is the level of f*****y LG and TMO have done to this version of the V30.
I have an even better question.
Well, I was able to boot into what looks like TWUL but don't know what mode I should run when the options menu briefly flash on the screen.Well, I figured out my problem. I didn't read further down into the instructions. What a n00b.
To answer your question, I used a generic Patriot 2GB stick I got probably 12yrs ago. When I do things like this, I like to stay below 4GB.
However, I also converted the ISOs to VMDKs using the Virtual Box converter on the 2.7, 3.1, and 3.2 versions of FWUL and they all worked okay in VMware Workstation. VMs aren't recommended, but they seem to work fine.
Well, I was able to boot into what looks like TWUL but don't know what mode I should run when the options menu briefly flash on the screen.
I get a [rootfs ]# prompt on the screen.
I'm trying to get all the assistance I can because this is, by far, the toughest part of this TWRP flash.
Also, the device doesn't seem to be recognized by the PC which means something is off.
Hi, in reading through the V30 forums I was on my way to unlocking and rooting my old backup V30+ and apparently got my wires crossed somewhere? I have a T-Mobile V30+ and I used the DualMode LGUP file to flash 20b onto it.
I *think* this is where I f*cked up since reading into more forums it seems like it doesn't like to cross flash with my model?
My fault yeah but I got there through some link hopping since I was on A9. Anyway, I have a black screen now. Can't shut it off, turn it on whatever. QUSB_BULK.
Any idea how I can unbrick this? I can handle whatever code or programs if I need to read into junk.
Launch day T-Mobile V30+ with the original Headphones. I got it myself by trading in my old V20+ I believe. I was following a guide to unlock the bootloader which mentioned flashing "US99820b_03_0524.kdz" First since I was on a newer version I think?WHICH 20b did you flash? For what model? It has to be for the T-Mobile H392, not any other models. H932 20b KDZ (stock ROM).
You have an actual T-Mobile H932 V30+ (128GB)? Those were only sold for limited time. Most H932 are the V30 (64GB).
Why 20b? To root the T-Mobile H932 you would be using Nougat 10d first, if you read these directions. There's no mention of 20b in these instructions, whereas for the WFT instructions you have to use early Oreo like 20a or 20b for the bootloader unlock exploit -- but those instructions are not compatible with the T-Mobile H932. The T-Mobile H932 is the hardest to root and can only be done by this specific method in this thread.
If you actually have a T-Mobile H932 V30+ or even the 64GB V30 H932 and you flashed any other model (US998, H933, H930*, H931, VS996) full KDZ over it, you have permanently bricked it. We have plenty of warnings everywhere about NOT cross flashing other stock firmware over T-Mobile H932.
To root the T-Mobile H932, you do have to flash a single partition (LAF) from the H933 (Canada) Nougat 10d, but that's ONLY after you have unlocked the bootloader. That relaxes the security chain enough you can safely flash that one partition from another model (but it's still scary) to then install TWRP and root through a very convoluted method. The OP who came up with this is a genius, but you have to follow the steps exactly.
Brother I have LG-H932PR but i select file for LG-H932 in LG UP. During update my phone become brick. Need your help to fix.Hmmm....
Just be careful. This method in this thread is only for T-mobile H932. All other V30 would use WTF method -- including H932PR. H932PR (Puerto Rico) and T-Mobile H932 have nothing in common except for LG's laziness in not calling it H934 or something... You list Santo Domingo in the Caribbean as your location, so just double checking.
