aaah, my beautiful, large screened baby is back in working order shipped to me with H81110N. Happy happy! Joy Joy!

And, G4 Tweaksbox is due otu later today :)
[G4 General] thevmax:
Just got mine back from LG on Tuesday, 09/15/2015 and I noticed that I don't have an update number. Mine says Anti-rollback Version Non-fusing device. Here are the screen shots after installing xTreme 2.0 on top of H81110n stock, which was installed on top of H81110h stock.
[G4 General] Barsky:
Mine says Anti-Rollback Version 2. Everything else on the screen is that screen is the same as yours.

Wonder what Non-Fusing means?

Man, after being on that little LG Leon for over a week, this is like having a brand new phone all over again. Exciting :)
[G4 General] thevmax:
Anti Rollback Non-Fusing device

* I think it means that the IC can't get messed up and won't cause the issue I just had.

NO...I won't try to flash an older ROM!

I've learned my lesson...still... I wonder ?:cool:

I actually thought about buying an LG LEON, as a backup, when I am in between smartphones because it is a pretty cool phone. :good:

You would have thought the Leon was king if you were on my backup: ATT Gophone!
[G4 General] Barsky:
It was $89.99 on sale at Best Buy. The gui is very much like the G3/G4 as one would expect, so it was not a bad thing having to use it. And the small size was sorta nice in some respects. Damned impressive for a $90 phone that gives peace of mind between phones or in repair situation.
[G4 General] waylo:
Well that certainly is interesting. I got a brand new replacement and when it updated itself from 10d to 10h when I first opened it, there was nothing listed in the antirollback section. Once I updated to 10N, it listed the "2" that we all see.

Looks like you have the 'golden sample!' haha. Probably will advance the next time a new update rolls in. But we'll see.
[G4 General] montusk:
Is there a way to know the anti rollback version just from a kdz without flashing it?
[G4 General] RenaKunisaki:
When I wiped out the flash on mine, the repair statement said they replaced the mainboard... Figured they'd just flash it. But it might be a way to speed up the process; just quickly swap the board, fix that board later and use it as parts.

Anyway, so this doesn't apply to every update, only to a few that update the bootloader? So I wonder what they changed? Would be interesting to look at the differences, maybe they patched something that we can use on old versions...
[G4 General] thevmax:
I received mine with stock 10H. Then installed stock 10N, and then Xtreme 2.0

Dealing with LG and TMO over the phone today about unlocking and so I switched back

to stock rooted 10N and I still have Anti-rollback Version Non-fusing device.
[G4 General] waylo:
How did you install 10N stock? OTA update?
[G4 General] thevmax:
I flashed from XDA G4-H811-10N-STOCK-ROOTED-ROM.
[G4 General] waylo:
Okay, so the bootstack/radio was never updated then. Don't know if you need to per se. Keep running with what you have if you're not having any problems!
[G4 General] thevmax:
But I am having problems...low phone signal over 4G LTE (usually 1 or 2 bars), overheating, high battery usage (1.5 batteries per day), reported garbled/digitized conversations from people I talk to. Yesterday, 09/20/2015, I was talking to LG Tech and he said it looked like my signal down due to the phone being sim locked to T-Mobile. HE called T-Mobile to see if he could persuade them to unlock my phone and they told him to call LG! He said he was from LG!
[G4 General] MicroMod777:
The LG Tech thinks unlocking your sim will give u better LTE?
[G4 General] thevmax:
YES.
[G4 General] RenaKunisaki:
That's certainly odd. And you didn't have these problems before flashing?
[G4 General] waylo:
Well, maybe you should consider flashing the updated bootstack. Having mismatched radios has caused problems before.
[G4 General] thevmax:
I don't think that's the problem. This G4 has had phone problems since day 1, with a T-Mobile SIM from the T-Mobile Corporate Store, T-Mobile APN, and full stock ROM, with all the bloatware. That's why I sent it to LG. They could not find any problems with the phone, but they never mention, in detail, what tests they have done. When I had the T-Mobile SIM, I called T-Mobile, and eventually got to Tier 3 level. Even though they offered some things to do from my end, nothing helped.
[G4 General] waylo:
Unfortunate. Maybe you have a lemon?
[G4 General] ramjet73:
Can you re-create the problem(s) at a T-Mobile store? If the issues you are having occur routinely you could call T-Mobile customer service, demonstrate the problem(s) to the staff at the store, and request a warranty exchange. That's what I would do after all the testing and repairs you have done already.

BTW, my G4 is on it's way back with another "repaired" USB port, but I won't receive it until next Tuesday.

ramjet73
[G4 General] thevmax:
Not purchased at T-Mobile store, plus, purchase occurred July 22,2015, which was 2 months ago.
[G4 General] ramjet73:
According to this page T-Mobile will replace your phone and return it to the manufacturer if it is defective and still under warranty (one year for the G4) for $20. It doesn't state that the phone has to be purchased form T-Mobile but you may have to produce a receipt if it wasn't . Of course you need to be a T-Mobile customer to take advantage of that option and have purchased the phone from an authorized dealer (Best Buy, Walmart, etc.). If either of those is not true I guess you are on your own at this point.

ramjet73
[G4 General] thevmax:
All T-Mobile does is send the phone is for you with an extra day delay. I've sent my phone in to LG directly, 3 times, and the only thing they found defective was the Power IC was shorted and replaced under warranty. There is no question that my phone is under warranty. LG says they can't find anything wrong with it. But everyone I talk to says that my conversations become garbled or digitized within 20 minutes. T-Mobile doesn't give a s**t! Since I did not buy from them directly they could care, but have decided not to. I have a receipt from Swappa.com. LG would not have covered the shipping and the one repair they did at no charge to me if I wasn't covered under their one year warranty. HOWEVER, it is up to LG's discretion as to whether they will replace or repair the phone. I have no say in that decision.
[G4 General] ramjet73:
According to the page I quoted earlier, under the warranty exchange program T-Mobile will order a replacement phone and you return the defective phone after the replacement is received, but the phone has to be purchased from T-Mobile or an authorized T-Mobile dealer which Swappa is not. I believe LG has the same policy about authorized dealers and original owner (non-transferrable warranty) so you are lucky that they didn't require a receipt to work on it and unlucky that they weren't able to fix your problem.

From the warranty as covered in the LG G4 owners manual:

(2) The limited warranty extends only to the original purchaser of the product and is not

assignable or transferable to any subsequent purchaser/end user.

ramjet73
[G4 General] thevmax:
Just for clarification: I do have a limited one year warranty with LG. Luck has nothing to do with it.

They did ask for a receipt which I provided. They also verified that the phone was new and never registered to anyone else. I am covered by LG warranty. I am considered the original purchaser because the phone was new, sealed, and registered by me.
[G4 General] Barsky:
I have had two 100% satisfactory repair experiences with LG in the last few months,. One when my G3's sim slot died. the last with my bricked due to trying to flash 10h over 10n kdz, G4. I now have it back, fully repaired on 10n. Both times I waited nervously.

They do not appear to waste their time on silly stuff like whether you were rooted, alt-recovery flashed or otherwise. (otherwise including my stupid flash move :) ).

Go through the warranty process and you should end up satisfied.

This has been a moral support message!

P.S. I am not a paid shill :D
[G4 General] pakitos:
Sorry for my lack of knowledge and just to be clear.

This means I can not flash firmware 10A once I flashed 10E, right?
[G4 General] thevmax:
Paid Shill ...(NOT)

The only warranty process I have is calling them and complaining about the phone's performance. I can't force LG to replace my phone. They had the phone 3 times since July 2015. The last time I called, I suggested that they replace the phone. I was told it was up to the techs to decide that. Apparently they only replace the phone when they think they can't fix it. Since they think nothing is wrong, nothing had to be replaced...yada yada yada!

P.S. I am not a paid shill for one of the other carriers...
[G4 General] ramjet73:
This thread would seem to indicate otherwise and most manufacturers only honor their warranty when the item is purchased from an authorized dealer but it's great that you haven't run into that issue. Perhaps they were able to trace the original purchase back to an authorized dealer.

Good luck with resolving your audio distortion problem.

[G4 General] smkyle:
In regards to the original PSA warning I can proudly confirm that attempting a rollback will brick the phone. I don't have details on what versions I started and ended with, but I can say that I pushed a rooted image, the phone restarted and I got a security error, I tried to roll back by installing a kdz in download mode, and then I cried myself to sleep because I wasn't able to do a darn thing after that. It's also possible that my USB cord became disconnected at some point in the process, but I don't think that's the problem. In hindsight I should have used a USB cable that didn't occasionally disconnect momentarily because then I could definitively rule that out. My phone is in the mail and we'll see if LG is cool about it. It seems that others are having good experiences with their warranty process at least in regards to fixing/replacing bricked phones.
[G4 General] legend221:
Thanks you for the PSA I've yet to see any KDZ images for my VS986 10B but higher versions are posted online. Was thinking staying on this version might make it easier to bootloader unlock. Unfortunately the forum unless you have a specific model number has been pretty quiet and by the end of the year maybe just flash to the higher version.

We value you for the information provided.

[G4 General] Pretzel Jones:
Need to rollback to 10H from 10N to unroot

So everyone that has bricked their phones, which version were you coming from and which version we're you trying to go too? I want to unroot and flash stock on my LG G4 so I can exchange it at T-Mobile. I think I got a lemon.

I bought my phone with 10H, flashed a rooted 10N ROM along with the bootloader. My current rollback version say 2. All I want to do is unroot and flash back to 10H because for some reason I can't find any stock 10N KDZ files in order to unroot. Unless there is another method???

Please help!!!
[G4 General] Barsky:
This is the exact method to use if you want to HARD BRICK your phone. I believe the entire thread tells you you cannot do this without bricking.
[G4 General] waylo:
There's a 10n kdz image on that kdz restore thread. That's the only thing you should flash.
[G4 General] thevmax:
You can't go back to 10H! Forget about it.

Your only two choices are: 1. Find the 10N Stock (it does exist on xda) or 2. Flash 10H, brick your phone, send it to LG! They will fix it. And they won't know you flashed incorrectly.
[G4 General] ahzs6455:
hmm abit too late should of read this before doing it
[G4 General] karendar:
I don't know if this has been posted, but I just checked the Canadian variant (H812) running on v10g and the Antirollback is still at v0... SubFW version still at v0 as well... Seems like Canada isn't as strict. :)
[G4 General] RenaKunisaki:
Which carrier? I think that's the more important factor than the model number.
[G4 General] sefirosu0522:
So I have the Verizon VS986. Came with 10B. I took the OTA to 11A. At that point, I did the low effort root. I know there is a KDZ file for 11A. If I use that to go back to stock, will I be ok?

EDIT: I actually may have been on 10B during the root process. Am I SOL?
[G4 General] RenaKunisaki:
From what I'm hearing, even KDZ might not be safe. You need to check the rollback number.

I'm not sure what you're trying to do, though. You rooted on 10B, then did OTA and lost root? You should be able to inject root into your own system.img. I don't think 11A blocks it. If it does, then you may be boned until another method comes along.
[G4 General] sefirosu0522:
Where do I check the rollback number? Right now I am currently running 11A rooted. I can't remember what my process was becasue this was done in the middle of July.
[G4 General] waylo:
Check the original post. Only works on some models though.
[G4 General] sefirosu0522:
Not working on Verizon.
[G4 General] Amnesiax:
So just to be sure, does this mean I can go from 10h to 10n via flashing?
[G4 General] Barsky:
Upgrading good.

Downgrading bad.

Never downgrade without checking if it is safe first. It Will Brick Your Phone.

So yes, h to n is ok.
[G4 General] NighthawkXL:
For those that seem to not be able to find the 10N KDZ for TMO you can download it here. Seems like there have been several folks in this thread looking for it. It's not in the repository in the Return to Stock thread.

If someone could upload a mirror it would be awesome. I can't, currently on my mobile.
[G4 General] Norcalz71:
so to clarify the base of the thread:

entering that secret code and getting the menu screen, I do NOT have a line called anti-rollback version, it stops at the SE Policy line. If this is the case, then I am still on v0 and my rollback counter has not "started" yet, correct? This is on an 810 AT&T model bought on the release day in store. It did take the small OTA that some of us got stuck automatically taking (never prompted me, just did it) but since then I have not taken any OTA's whatsoever. I am on software version 10e.

Thanks
[G4 General] dspcap:
So I am on version 2...meaning I can flash any version of 10n and am fine....just don't flash 10h?
[G4 General] cowsquad:
Good to know about this thread. Anyone on Verizon capable of using a similar code to verify this status. I think a11 has v1 already
[G4 General] agentms11:
I have an SEA H815 and there's no 'Anti-Rollback' in the *#*#244773825625#*#* menu. Hope that means they're more lenient on these.
[G4 General] iamtha1:
Mine dont have anti rollback info either... And im on 10g..
[G4 General] rustypie:
I haven't found a definite answer anywhere for the Verizon VS986 G4. How are we able to tell what bootloader/anti-rollback were on? Can we KDZ from 12A back to 11A? The dialer codes don't work on the Verizon variant.
[G4 General] waylo:
I don't think anyone knows at this point. Lots of people posting asking about the Verizon variant, no answers. Sorry. [MENTION=2684188]autoprime[/MENTION] has been able to poke around into KDZ files to see the version #s, not sure if he has chimed in on this specific question.
[G4 General] jesssiii:
I took the 12A OTA then rooted it. Then used KDZ back to 11A. HARD BRICK. Don't do that.

LG G2 VZW
[G4 General] autoprime:
ouch. for future reference and anyone else in similar situations... proper way to get around this would be to be rooted... then flash 11A boot.img using adb (or flashify)... put the 11A system.img on internal sdcard.. then boot into download mode and flash the 11A system.img using same method used to root (send_command.exe etc etc). This way you'd be on 11A boot/system while staying on 12A bootstack.

system/boot should always be paired if possible.. but the bootloader doesn't need to be touched.

you could also upgrade via this method and avoid taking OTA/KDZ which blow more fuses.
[G4 General] omariscal1019:
So am I "v0" no anti rollback. [MENTION=2684188]autoprime[/MENTION]
[G4 General] jal3223:
So is is possible for those of us on 10b (on Verizon) to flash the newest system.img from the latest ota and remain on our 10b bootloader?

It would be awesome to be able to benefit from the new fixes and still have the exploitable bootloader.
[G4 General] jesssiii:
I wasn't able to use the current method to go to 11A from 10b. Had to do the KDZ or OTA first, then put the rooted 11A on. So [MENTION=2684188]autoprime[/MENTION], what exactly are you saying for those of us without recovery or unlocked bootloader? I mean using the root method you and your's kindly provided.

LG G2 VZW
[G4 General] laurasaurisrex:
Not by flashing only the system.img, no, but I think [MENTION=2684188]autoprime[/MENTION] meant that if you flash both the system.img and the boot.img, you should be able to boot into a different version while remaining on your original bootloader? I hadn't seen anyone try this anywhere.

I have 10b, so does that mean I can flash the system.img and boot.img of 12a, but retain my ability to get the bootloader unlock, since by bootstack will still be 10b (v0)?
[G4 General] kbuck13:
Where can we get both 11A images
[G4 General] jesssiii:
Where/how would you get the boot image?

Boot image, how to get it using adb? Or download mode commands?
[G4 General] laurasaurisrex:
Someone running 11a needs to volunteer to dump it for us. I think I've seen the commands somewhere in the depths of the low-effort root thread...
[G4 General] danaff37:
Here if someone on 10b wants to try it, this should be the 11a boot image from my device

https://www.dropbox.com/s/ufwl78e6ela5nei/boot.img?dl=0
[G4 General] waylo:
Anyone trying to update their system/boot but retain their older bootstack, just be aware some users who accidentally did this by flashing updated .imgs but neglecting the bootstack had bootloops or an authentication error. So proceed with caution and a way to restore your older system .img/boot partition.
[G4 General] Norcalz71:
just got my warranty AT&T 810 and it came on version 10g (my original phone which died is on 10e) and i do not have the anti roll back item at all, let alone at one. is 10g still not tripped the counter?

EDIT: and unfortunately spoke too soon. My phone updated before i could debloat when I wasn't watching it and I am now on 81010o, anti-rollback version 2....fantastic.
[G4 General] Nima79:
818p . 10f . there is no roleback
[G4 General] delivery_dragon:
So, are there any reasons I would want to stay on 10h and NOT upgrade my bootstack to 10n? I've combed the forums and (sorry if I missed it) everyone I can see says the 10n update is better than 10h.... I just switched to T-Mobile from Verizon (S4) and this is my first LG device as well. I'm aware I can't go back to 10h once I leave, but since H8110N is still bootloader unlocked and rootable(correct me if I'm wrong), is there any reason to stay on 10h? I'm hesitant because when I got my S4 it was already updated past the point of being able to unlock the bootloader, and GOD was that a pain. Sorry if I missed the answer, I've read almost everywhere on the forum and couldn't find it.
[G4 General] waylo:
No reason to stay on 10h on t-mobile version. We can install twrp and have oem unlock, unlike other models which are awaiting unlock and the anti rollback might affect a pending fix.
[G4 General] MicroMod777:
10H is a crappy build. 10N is way better.
[G4 General] TheBledard:
Hi all,

Is there any "anti-rollback" feature on H815 ? The thread concerns essentially version in the USA...

no its the same for euro saw the flashtool is not update with the new dll...
[G4 General] iliavlkv:
need repair H811

so how we can repair our BRICKED H811 model??? no any solutions??only LG service???
[G4 General] MicroMod777:
Nope! I just bricked mine also doing something else and there's no recovery at all if you can't access download mode. Just call T-Mobile and they'll send you another one under warranty. I got mine UPS Next Day Air for $5 bucks. Waiting for it as I type! :)
[G4 General] iliavlkv:
need repair H811

unfortunately I`m not in US for the moment and I can`t change it under warranty..so I check the solution of this situation..waiting for OCTOPUS updates maybe it can resolve my problem with JTAG???

---------- Post added at 08:52 PM ---------- Previous post was at 08:49 PM ----------

Also I saw a lot of posts on Google search that LG G4 H811 can be repaired in Vietnam?? if they can why we can`t???? or it is fake??
[G4 General] fonzinator99:
T-Mobile H-811 here, TWRP recovery. Had been on a debloated stock, 10H, Upgraded to a 10F, Marshmallow 6.0 ROM that turned out to be much buggier than I'd like. Wiped everything, tried to flash the backup I'd made, and when it came to I started getting "Process system is not responding" errors and huge lag spikes that have left it largely unusable. Now I'm here, looking at flashing a 10N via KDZ, and wondering if I'm wasting my time and totally f'ed.

Does anyone have any thoughts?
[G4 General] iliavlkv:
Do't try to downgrade your phone!!!!

Otherwise you will have beautiful brick as LG G4..

---------- Post added at 09:27 AM ---------- Previous post was at 09:22 AM ----------

I'm ready to donate to the developers who will make any solutions how unbrick our LG G4 H811 models..
[G4 General] waylo:
Depends. How did you load the marshmallow rom? If you did not upgrade the bootstack, you could be fine downgrading. Most roms do not include a bootstack upgrade and this is flashed separately.

You could try flashing micro's stock 10n rom only. This doesn't touch the bootstack.
[G4 General] fonzinator99:
Well the whole downgrade=brick issue isn't mentioned anywhere in the t-mobile forums, so I wasn't exactly aware of all of this at the time. Otherwise, of course, I would've just avoided this entire issue -.-

The marshmallow was loaded by dl'ing the ROM to my ext_sd and wiping/installing through twrp. It's worth mentioning that I can still get into recovery, the phone still boots, and at the moment it's even cooperating with me as far as doing stuff. So I have to believe it can be saved :p Current plan is to flash from http://xdaforums.com/tmobile-g4/development/rom-g4-h811-10n-stock-rooted-rom-t3188858 but I'll hold off to wait for a reply, cause I'd like to be sure that I'm doing this right.

Should I flash the 10N bootstack like it says, or just go straight to the ROM?
[G4 General] fonzinator99:
Seem to have fixed my H811

Right, so first off, I cited my ROMs wrong, despite edits -.- I hadn't attempted a 10F, but instead the 7 HD M port found here: http://xdaforums.com/tmobile-g4/development/global-marshmallow-6-0-port-to-h811-t3232760.

My bootstack was still at 10H though, and I'd been trying to flash the stock-debloated-10H ROM that I'd started my root efforts with months ago.

I went and flashed the 10N bootstack, followed by Micro's H811 10N xTreme ROM, dirty flashes, cache/dalvik wipes afterward, and things seem to be back to working order. Not lagging anymore, System processes aren't crashing or hanging, and I can get into my security settings and all without FCing.

I think this particular issue can be marked as "Solved," and I appreciate all of the assistance given. Thanks for keeping me from losing hope :good:
[G4 General] waylo:
Glad you figured it out! Yeah, 10N is pretty steady at this point. Recommend sticking with it until there's an official M release that's rootable.
[G4 General] 48bloo:
How were you able to flash anything when your phone was bricked? Just bricked mine and I'm really confused as to what steps I should take to recover from this.
[G4 General] fonzinator99:
I'm afraid my phone wasn't actually bricked at any point, just buggy as hell/freezing constantly cause all of my ROMs were trying to rely on a newer bootstack that I didn't have. It still booted and could reboot to TWRP, so I just upgraded to the appropriate 10N and read comments until I thought a ROM seemed stable, then flashed it.

Sorry I can't assist :(
