[Q] LG Thrill GB w/ClockworkMod Recovery

(Obvious Noob warning---) A friend helped me root my Thrill, install ClockworkMod Recovery, and then install CM7 on my Thrill. But I would like to try the LG GB release. Is it necessary to backtrack all the way back to stock to do this (i.e. reinstall the stock ROM, reinstall the stock recovery, unroot, etc.)?
My friend tried using the LG upgrade tool on his LG phone without going back to stock and ended up bricking it. He says that usually within a few days of release, a CMR compatible zip file (usually already rooted) appears here on XDA (I haven't seen it), which makes things easier (but obviously he didn't wait for it himself).
Will a zip be possible for the Thrill GB? (The file seems quite large (420MB), so I'm guessing there is a lot of media included.) Or should I just bite the bullet and backtrack?

I'm assuming that the official update method was used.
Just use this method after downloading the update. No bricking.

Trojan?
Sorry, but as a noob, I can't post in that other thread.
It seems that the shttp3.exe in the LG Flash Package triggers Symantec's trojan detection. Some searching seems to indicate (assuming I'm reading all the cryptic virus sites correctly) that there is something to this, although it seems that different scanners find different trojans/viruses (can't post the link, but Google for "shttp3.exe" and "trojan"). I also found that the web site for this utility is blocked at work, because it's a "malicious site."
Has anyone seen this? Has anyone been able to verify/refute this?
Rick

There is no virus, Lestat would never do that

Just my .02 .....Get rid of Symantec !! They are known for scaring people into a virus frenzy.. Yes, it is possible that it is seeing it as a potential virus because shttp is a workaround from the usual porting of windows ip services. ...
Correct me if i'm wrong somebody please !!
Get yourself Comodo and save your money...
Regards,
Dwayne
PS: somebody on here has written a script that just uses shttp temporarily while
your doing the flash procedure, and then reverts your host files back automatically after your done. You should try it.

I'm sorry I can't give the link yet, but if you'll Google you'll see Comodo classifies shttp3.exe as "ApplicUnwnt.Win32.ServerWeb.SmallHTTP.~A" or "UnclassifiedMalware" (I guess depending on the version). A number of scanners find issues with shttp3.exe. I'm not saying it is infected, only that it is doing something suspicious.

shttp3.exe is in no way a virus. I've scanned with AVG and MalwareBytes Anti-Malware and they check out good.

Back to square one
OK, I seem to be stuck.
With paranoia in tow, I decided to take the long way back to stock. Unfortunately, when I tried to restore the backup of my stock image I made to SD card after installing CMR, the md5 checksum failed. I'm not sure what I can do about this.
So ok, I tried following the above link. The first step is to ensure the su binary is up-to-date. But when I tried this, I get a failure downloading the manifest. This is true for WiFi and HSPA+. I Googled and found a suggestion to delete the su binary. But that didn't help (I'm not sure how it would have helped anyway).
So back to the original question. Can I use the LG upgrade process to upgrade without going backwards (as you can see above, I can't) without bricking the phone? Can I start at step 3 in the link above and succeed?

Is it safe to ignore the su version update?
Short of this, can I override the MD5 checksum? I realize that image could be corrupt, but if I'm just going to replace it with the GB release, does that matter?

You should just put your phone in recovery mode and update through the tool
with your IMEI #. It will give you the latest update !
If you need some help on that I think Lestat or somebody has a write-up
on doing this.
Good luck,

Can you be a bit more specific?
1. By "recovery mode," do you mean into ClockworkMod Recovery, or I should revert to stock (I made a copy of it after I rooted the stock ROM, but before I installed CMR)?
2. By "the tool," do you mean the official LGMobile Software Update, or the LG Flash Package referenced in the link above?
3. By "latest update," do you mean the file directly from LG, or the copy (v20p) linked from the link above?
4. If the latter in both previous questions, which set of steps do I need to follow from the above link? Can I do only 3 (LG Flash Tool), or do I need to follow 1 (Recovery Manager), 2 (Returning to Stock), and 3?
My friend had a different LG phone, with ClockworkMod Recover and CM7 installed. He reverted the CM7 to stock, but did not replace CMR with the stock recovery. Then he used the official LG upgrade method and bricked his phone. I'm trying to avoid this.
Are you saying I don't have to worry about this on the LG Thrill 4G? Can I go straight from the current CMR+CM7 configuration to the LG GB release using the official LG process?
If you mean I should use a different process, can you point me to it? As I mentioned, I run into dead-ends using the method linked above. And I'm not even sure whether I should be doing steps 1, 2 and 3, or if I should just use step 3.
Any and all help is appreciated, but I guess I don't understand the shorthand you're using here, so if you could be a bit more specific, I wouldn't feel so lost.

Remove your battery and keep the phone unplugged
Launch the mobile updater tool
Hold the volume+ button plug the phone in and keep holding the volume+ till the computer downloads the drivers your phone is now in download mode
Once the phone is picked up go to customer support on the LG updater tool and click on recovery phone put your imie number in click check (make sure its the right model) an let the updater tool do its job. Once its done flashing launch into recovery volume- plus power plus 3D button do a complete wipe and factory reset and reboot your phone ... you'll lose cwm and root and be back to full stock

Bricked?
No joy. Following the steps, the upgrade stopped at 6%. Trying a number of times, it eventually forced me to exit the program (no more restarts). Rerunning the updater (and downloading the 420 MB image yet again on a VERY slow connection) I tried again and again, with different combinations of battery and plug order with power and volume buttons, but nothing worked. Checking elsewhere I found some issues had been reported with Windows Vista/7, so I tried on an XP machine. Now the "Start Updating" bar is red (it was always gray with W7). But now when I try to restore (or even update for that matter), it asks for my S/N (it never did that before) and then says it is "no longer able to upgrade." Reading around, it seems this is an indication of the device being bricked.
Rick

It sounds like you are very close to getting it working Rick.
My update did the same thing, looped over and over until it
finally kicked me out. Just plugging and unplugging the phone etc....
And when my update stuck at 6% the last time, i took my battery out and then in real quick and that seemed to work.
Does the phone still vibrate when you plug the usb cable into it while holding volume..? If it does then I highly doubt that your phone is bricked, just in a semi flashed state....No worries
Should Rick be trying to run LG Updater as administrator ? I didn't, but it might not hurt.

I tried a bunch of different combinations...none seemed to make the app happy. I finally punted Windows 7 and moved to an XP machine, only to get the "no longer able to update" message. At that point I assumed I was screwed (effectively bricked).

It never really vibrated, but I was able to get back into CMR. Unfortunately NONE of my backups work at all. They all have MD5 checksum failures. I tried a trick I found online and got past that step, only to have it say a failure restoring /system. So much for CMR.

Which step? As I mentioned above, I can't even get the first step of the first section (updating the su binary). And if I start at the 3rd section, Symantec prohibits me from using shttp3.exe (I tried to unquarantine it, but it gives a permission error, even as Administrator, when I try to run it), so I'll have to use a different machine.
I was able to reinstall the CM7 3/15 release, so that's something. I was going to restore the stock recovery backup I made, but even that doesn't seem to work. I'm having issue with backups :-(
Rick

i have never been able to restore a backup. i dont know why... but i have tried several times in several different instances.

Need Stock Firmware G900AUCU2AND3!!!

I need the Stock Firmware version G900AUCU2AND3 So that I can flash back to stock. In the thread return to stock it has the previous version G900AUCU1ANCE. I get a error when trying to odin back (SW REV CHECK FAIL : [about]Fused 2 > Binary 1). So I am not sure how its done but need someone who has it do a dump or how ever its done to get it in a way that it can be flashed either by odin or in recovery... Any help will be appreciated... Thanks

i will need this too, i have my phone on at&t next and after a year i can trade it in, but if its custom os and stuff i cant return it, so i will need this too if i want to return to stock so i can upgrade to a new phone next year.

Bump: This is needed very badly. As I imagine many people had to take that bloat ware update. If anyone that has this firm ware has a problem and needs to restore back to stock. They won't be able to use the one that's listed in on this forum as its the older one, and now that there is Root. Its very likely this will happen daily that people will need it. I don't know exactly what soft bricked my phone so it can happen to anyone. My phone was fine until a reboot. Please, please, please. I'm begging everyone that has it. I asked Samsung and they wouldn't help. Next maybe going to AT&T store and having warranty claim done. I don't really want to find the out come of that.

I need this very badly as well. I rooted my phone and then tried to alter my screen density via an app I found on Google Play. It requested root, I granted the permission and then when the phone rebooted it hung on "Samsung Galaxy S5" splash screen and will no go any further. ODIN will not allow me to flash G900AUCU1ANCE firmware since I did the OTA update. If anyone could post up their G900AUCU2AND3, I would appreciate it very much.

I estimate we will get @ least One to two of these per-day until we get the files. Since we now have Root. It may take a bit as At&t version don't seem to have much for devs. Or ones that care to really help.(I'll probably get reamed for this. Sorry for you that help and for your time) I contacted At&t they told me they could not help but I could send my phone in for warranty exchange. Its that or go to BestBuy and they can flash it back. I don't have a Bestbuy Nearby.

Guys, check that post. Shortydoggg found a temporary fix for any soft bricks. It's for extreme cases. My phone is fine (apart from some deleted stock apps) so I'll hold off until i get some more info but if you cant boot at all, his method should come in handy.

YUP, I did the AT&T update check and got it immediately afterwards. I instead of flashing every one separately and rebooting loaded the three files so minus the Bl file. I did not have the problems of having to reload APN this way.

A flash of the CSC file restores the APN after flashing the AP file, or flashing it together with the AP file, but it factory resets the phone. Flashing the AP file only is mostly for those who do not want a factory reset. But, a factory reset along with flashing only the AP file will indeed wipe the APN. I found all of that out through trial and error.

There should only be two boxes checked in odin thats f. reset time and auto reboot. Also Make sure you only check and load your firmware in the ap slot in odin. Now flash.

Yea I did thank you. Did it today and thanked the poster too.

Want to start over! Need help!
So I want to do whats written out in step 4 of shorttydogs thread but I don't want to mess up or brick my phone. My goal is to start over and go back to stock with bloatware and everything that is available on stock if I were to go AT&T and buy it today. Here is a little background on my phone. My phone is rooted and I do have safestrap (and busybox). I backed up everything on my microSD card. I also have the g900AUCU2AND3 firmware on my phone. In addition, I deleted some but not all AT&T bloatware, which I want back. Lastly, for some reason the "add call button" during my calls is missing and was replaced with a "record" button I think this was because of me playing around with xposed. I deleted xposed framework as well as wanam and tried everything to get the "add call button" back but I couldn't. Thus, I just want to go back to stock to fix all these issues. I just have a few questions before I proceed just to make sure I'm not doing anything wrong.
1) If I flash the AP, CP and CSC files will I achieve 100% stock with bloatware?
2) Will this return my "add call button"?
3) Is it as simple as just using odin 3.09 and flashing the AP, CP, and CSC files?
4) I also understand that this will take me back to G900AUCU1ANCE but will I be able to do an OTA do go to G900AUCU2AND3?
5) Is there anything else I need to know to prevent my phone from bricking!
Sorry for the long post but I am fairly new to this stuff and don't want mess anything up!

The factory reset protection has me curious. I think the better question is can then somehow block TOT flashing.
We won't know if the old root method will mess things up. I would just wait for a v6 image to be released. Someone did make a post as a how-to root the image yourself if you can get it off the phone. I would just wait.

someone needs to capture the OTA and get it to me so I can check it out.
I'd suggest holding off on actually applying the update until we know what's what.
Thx in advance.

Let me know when you have it

sent you a PM as well but I'll say it in here just in case you check here first. got it.. thanks again!
so.. after some poking around I can confirm...
ZV6 updates the anti-rollback version yet again, this time to "v2". If you flash this update or any part of the zv6 bootstack or zv6 modem it will update parts of your phone you will never be able to downgrade. This would also stop the ZV5 TOT from working... but to be specific.. ZV5 TOT will flash.. but your phone will be BRICKED after.
ZV6 does not seem to unlock the bootloader. I'm about 90% on this after initial code review. Perhaps some poor soul will take the OTA and be able to confirm this without a doubt... but it looks like the "Factory Reset Protection update" (related to oem unlock in development settings) has nothing to do with unlock status itself.
If a ZV6 TOT is somehow acquired in the future... the system and boot partitions could be extracted and used on the ZV5 bootstack... possibly ZV4 as well. Basically... boot.img and system.img would not blow any qfuses to permanently set a "version".
Bootloader/bootstack consists of aboot, sbl1, sec, rpm, tz, hyp, pmic, sdi... and then theres the modem. Flashing any ZV6 partition mentioned in the prior sentence will blow your fuse to "v2".
As for root... it's hard to tell without the device in hand to be honest... but I would assume it's still able to be rooted. So taking the OTA would not be the end of the world... you'd still have root. But you'd lose the ability to flash the ZV5 TOT without bricking... and it once again updates your bootloader version which may be blocking previous holes in a v0 or v1 bootloader we have not yet found.
I am not sure why LG and the US carriers have done this. I could understand the v1 update.. as that would separate USA from the rest of the world and make bootloader unlocking harder. To update it to v2 just doesn't add up... not yet anyway.
tl;dr
If you want to stay on a v0 (ZV4) or v1 (ZV5) bootloader version.. don't update.
If you couldnt care less about the bootloader and only want root... ZV6 should still allow that.. but the ZV5 TOT would no longer be able to be used.

So I can install this in the stock recovery (I am not rooted) because there is an option?
(I am doing it now but it seems to be stuck on "patching system files", uh oh)
edit: I am fine now, it installed fine. Was a little un-patient
I notice now the icons at the top are more stock android like with the "!" point if there is no internet. Pictures
Also the phone "feels" faster, I hope we can uncover what is under this update.
I hope this doesn't fix my free hotspot trick.

So if the OTA pops up, I can download and install it and still have root? Or has that been undetermined to to this point?

sent you a PM as well but I'll say it in here just in case you check here first. got it.. thanks again!
so.. after some poking around I can confirm...
ZV6 updates the anti-rollback version yet again, this time to "v2". If you flash this update or any part of the zv6 bootstack or zv6 modem it will update parts of your phone you will never be able to downgrade. This would also stop the ZV5 TOT from working... but to be specific.. ZV5 TOT will flash.. but your phone will be BRICKED after.
ZV6 does not seem to unlock the bootloader. I'm about 90% on this after initial code review. Perhaps some poor soul will take the OTA and be able to confirm this without a doubt... but it looks like the "Factory Reset Protection update" (related to oem unlock in development settings) has nothing to do with unlock status itself.
If a ZV6 TOT is somehow acquired in the future... the system and boot partitions could be extracted and used on the ZV5 bootstack... possibly ZV4 as well. Basically... boot.img and system.img would not blow any qfuses to permanently set a "version".
Bootloader/bootstack consists of aboot, sbl1, sec, rpm, tz, hyp, pmic, sdi... and then theres the modem. Flashing any ZV6 partition mentioned in the prior sentence will blow your fuse to "v2".
As for root... it's hard to tell without the device in hand to be honest... but I would assume it's still able to be rooted. So taking the OTA would not be the end of the world... you'd still have root. But you'd lose the ability to flash the ZV5 TOT without bricking... and it once again updates your bootloader version which may be blocking previous holes in a v0 or v1 bootloader we have not yet found.
I am not sure why LG and the US carriers have done this. I could understand the v1 update.. as that would separate USA from the rest of the world and make bootloader unlocking harder. To update it to v2 just doesn't add up... not yet anyway.
tl;dr
If you want to stay on a v0 (ZV4) or v1 (ZV5) bootloader version.. don't update.
If you couldnt care less about the bootloader and only want root... ZV6 should still allow that.. but the ZV5 TOT would no longer be able to be used.

Thanks for poking around and seeing what's what. If I were inclined to update my rooted ZV5 to ZV6 (understanding the current TOT restore would brick my phone) how exactly would I keep root?

I dont think you'd be able to keep it. You'd most likely have to re-root with a ZV6 rooted system.img... same way you rooted ZV5.

How did you manually install the update? I've looked up guides online but they say you need to install the Android SDK and LGFlashTool and such, which I messed around with but I can't really grasp on how to install this. Putting my G4 into download mode and trying to detect it via CMD did nothing (USB Debugging is checked).
Sorry, maybe somebody can lead me in the right direction, as I really want to try out this update and I'm also very impatient lol

It requires an sd card..copy the file to the root of the sd card then power off the phone. Hold down volume down then power till you see "recovery mode" then release. Once stock recovery loads use the volume down to the last option, something like install update and press power. This will bring up the directory from the sd card. Select your file with volume down and press power.

OH MY GOD
Thank you.! I'm installing it right now.
It's funny too, cause I saw people go into their recoveries on the LG G4 and assumed it was the same for all carriers and the International Version (I saw the generic locked recovery that only said "Are you sure you wanna delete all data?" or something, basically your only option was a factory reset). I thought it was that locked down on our phone, so I didn't even bother going into the recovery.
Thank you very much dude, wow...I feel dumb. And I used to run a GS3 with CM12 and CWM, and the stock recovery has some pretty good features on it too. Not too bad lol
*facepalm*

Can this be done even on rooted ZV5?

Probably. I installed the update and have noticed a few small touches in the UI, but notably a more responsive keyboard and overall faster phone. Knock code is also a bit more consistent and snappier for me as well, so I'll probably be using that from now on. Great update from the looks of it so far.

You may need to pull the card out and put it on a computer and format it using SD CARD FORMATER. If you Google it you will find it. I know with other phones I've had that solved recovery being able to read it. You are copying to the "external" sd card?

ZV6 Root Success !!

I got impatient waiting
I followed all the documented procedures.
You apply this exactly like ZV5 Root. This is only for LS991 (Sprint).
I've tested Root Explorer and WIFI Tether Router. It hesitated a little on the first attempt to grant root, I was probably rushing.
Once you apply this image on first boot it will want to upgrade Super User and you have to use "Normal".
YOU MUST BE ON ZV6 before you use this.
http://softronix.com/g4/Rooted.LS991.System.ZV6.zip
Not responsible for any bricking. I followed all procedures posted and I'm not gonna replicate it here.
Make sure you backup your unrooted ZV6 System image. I diffed my backup with the one uploaded by another developer and they are different.
I also tested rerooting a ZV5 stock image and it is different than the one uploaded in the ZV5 Root thread.
Oh, I should mention, I restored my ZV5 image first.
Then tried to take the ZV6 OTA update. It just stayed stuck "Now Rebooting". Tried manually rebooting. And it just went back to ZV5 boot.
So then I tried applying the update through the SD Card. That failed too, I guess it doesn't like my format of SD Card (didn't want to wipe that).
I suspect if I factory Reset ZV5 the AV6 OTA would have been fine, but I didn't want to do that.
So I noticed the ADB Sideload upgrade option in Recovery and tried that and it worked fine.
It even gave you the command syntax for ADB sideload. I had to upgrade ADB to make it work (adb sideload told me the verision I had was too old, which came from the LG_Root.Zip).
I have not done a lot of testing. I can't say tomorrow that LG didn't add some sneaky app that removes root or something. But at this moment it seems fine.
Feel free to mirror it.

How has this been working for you so far?

No problems. Even tethered while roaming with Wifi Tether Router.

Thanks for this!
I picked up a G4 a couple weeks ago for a basically a song. After reading that one thread you wrote, I figured.. why not give it a shot?

Which post, moving from M9 to G4?

Don't wanna sound stupid but how do I install this? I'm new to rooting.

Never mind I found the root tutorial you were referring to...but at what part of the tutorial do I use the image file you attached in the post? Once again sorry if I seem to be lacking common sense (because I am).

You do exactly what the ZV5 root thread(s) do. But you need to be on ZV6 and then use this rooted ZV6 image instead of being on ZV5 using Rooted ZV5 image.

Can someone provide the link on how to backup current stock system.img? I can't seem to find it.

Oh ok, so in this tutorial http://forum.xda-developers.com/g4/orig-development/root-tmo-vzw-intl-variants-soon-root-lg-t3164765 I just replace 'system.rooted.phonemodel.img' with 'rootedsystem.LS991.ZV6.img' and I'm good?

Yes, just make you do a backup first and you are on ZV6.
Backup is in 2nd post by autoprime.
Also be careful when copying dd comands from the web page that you copy the whole command.
note the horizontal scrollbar.

ZV6.img flash over ZV5?
I know the post said I have to be on ZV6, but I don't want to loose the ability to flash tot(I've bricked my phone before). Has anyone tried this? I've read other posts that say you can't reflash tot after taking the update, and nothing about updating through this method. Would this brick my phone, should I try it?

Corrupt file .zip?
I have already tried both WiFi and Phone network, but when I finally download the zv6.img file it says is corrupted and doesn't let me extract it. I don't know what is the problem please help me.

You don't extract the .img file. Just throw it in the sdcard directory root.

When you download the file it comes in a .zip file. That's what I meant to say when extracting and qhen I did didn't work. Anyways thanks, found another rooted ZV6 .zip on another post and that one let me extract the file in my phone. Don't know why this one won't let me.

Has anyone else had success with this?

A whole bunch of folks are rooted on ZV6. There is also a pseudo custom ROM based on ZV6 called Ultra Pop.
Read through the threads in Development.

Hello everyone. I just got a Sprint LG G4 today. I would like to root my G4 but not exactly sure how to do it. I have done some rooting in the past so I am a little familar with it. My software version is LS991ZV6, security software version MDF v1.1 Release 5. From what I read, the rooting process is for zv5, is this correct? Is there a rooting process for my software version, and if so, is there a tutorial for it? Does this also install a custom recovery or is there a different process for that? I know this is probably not the place to ask but since I am enquiring, are there any roms for the sprint ls991, ex mm rom, etc? Also, how can I find the files to disable OTA updates. I have googled it and it says to disable sprintinstaller apk but I cannot find that file in settings- apps-all. Also, I read to do a backup before trying to root. I am on stock recovery and when I go into that, there is no option to backup, am I doing something wrong. Thanks again for your feedback.

Going to try it now! Looking forward to trying out xposed! I really don't want to flash an actual ROM because I love the stock camera app way too much.. And the tweaks look awesome.

Hi im on zv9 but want to go back to zv6. Preferably a zv6 rooted. Which guide is the best to follow? If anyone who frequents here could link it would be greatly appreciated.
Thanks

LG G4 Bricked, authentication error, stuck in download mode not sure what to do!

ok so i just got my device about a week ago my phones on sprint and i thought i'd root it finally. I tried to root my device but i couldn't figure out if i was LS991ZV4, zv5, zv6 because i was on the latest firmware (i believe) but i have no clue what those 3 things mean sadly. It's been years since i tried to root a device and thought i could handle it. But i guess i can't.
Can someone tell me what i SHOULD be on currently if my phone was 100% up to date on sprint? And can someone please link me to a site that has the stock image for my device? i've been searching for over an hour now and the only file i can find is a TOT file which i BELIEVE is for ZV4 and if i am in fact on ZV6 than that means i can't restore it back to that image file. I'm in a serious bind here if i've permanently bricked my device.

update. i can't even get into recovery mode. ;w;

ok i'm seriously getting frustrated. I'm looking for the DLL file so i can attempt to restore my phone using the TOT method but i can't find one for this damn phone. SOMEONE please respond? ;w;

start here http://forum.xda-developers.com/sprint-g4/development/restore-sprint-lg-ls991-zv6-tot-t3213196 read the thread carefully it has all you are looking for and instructions.

At this point, it will difficult if not impossible to determine which firmware version you are on. My guess is that the phone was on ZV5 when you purchased it since ZV6 just came out. I got three G4s for work about three weeks ago and they were all on ZV5. However, if you took an OTA to upgrade the firmware then you would most likely be on ZV6.
Here is your quandary, if you are on ZV6 and use the ZV5 TOT, you will permanently brick your phone. If you are on ZV5 and use the ZV6 TOT, well, no one has reported what will happen in this case - best case is that it fails, puts you in a bootloop, or gives you an authentication error.
My advice to you, is to take your phone back to Sprint, tell them you were trying to take the ZV6 OTA, and the phone went into a bootloop. Pay whatever penalty you have to pay, chalk it up to inexperience, and read more next time before you attempt to root.
If you really want to get your phone back to working condition, I would try the ZV6 TOT again since that seems to not have completely bricked your phone. If that does not work (and because I think you are on ZV5), try the ZV5 TOT. However, if your phone is not on ZV5, this will most likely turn it into a paperweight.
All you need can be found in the G4 Android development forum: http://forum.xda-developers.com/sprint-g4/development
If you do manage to get your phone restored and need the base image files, they can be found here (also in the development forum): http://forum.xda-developers.com/sprint-g4/development/stock-sytem-image-files-zv5-zv6-t3205640
