[Q] How to unbrick soft bricked LG G2 LS980ZVA ?

I was rooted and messed up some system file and now my phone is soft bricked.
how do I unbrick it ? I seen this one to update firmware to ZV7 . one person said he had to do the zv7 then upgrade to get it to the latest firmware. Will this work ? http://www.rwilco12.com/forum/showthread.php?tid=96 I can enter download mode and do factory reset but need to know if this way will work on my device. this one is a sprint phone.

if you messed up the system files, you will need to re-flash stock to fix it.
all the files and guidance you need can be found here.

I tried the link you gave earlier but the program used uses a kdz file. I didn't know which one to use. What are all the files needed on the link you gave ? Which KDZ files are used for each different phone companies of LG G2 ?
I chose to use the download from the link I showed and fixed it from the "LG G2 Stock" folder download by following the instructions.
The link that I posted is the one for Sprint ZV7. Using that it unbricks it and then had to update software from ZV7 to ZV8 to ZVA to ZVC to ZVD. Not it's all updated.

i dont understand the problem.
there is a "sprint" directory on the downloads page with only sprint files there (including 3 of the builds you mentioned).

On the flash tool it says to select a kdz file. On the firmware link it shows different kdz files but which one is suppose to be used if it is ?
In the Sprint directory (home > Xda > LG G2 > Stock > Sprint) it shows a .dll file and some zip files. I looked at one zip file and it don't have a kdz file. Is that needed to use that flash tool ?

[Completed] Half Dead LG G2, No use of touch, imei, network

I have been stuck for over a month now and now I am forced to make this thread with the full story:
I bought an LG G2 D802. A few months later I updated it through the LG software update tool. This thing killed my phone. It installed lollipop and I then had these issues:
[1]no imei.
[2]no baseband.(FIXED)
[3]touch is not working properly. It is haywire. It does not respond properly at all and the phone is unusable
[4]no sim usage as no IMEI.
[5] ONLY 16 gb showing as memory available. (FIXED)
I did this. Using OTG to use my phone, I flashed stock d802 ROM (kitkat). This got me to Stock ROM but phone was boot looping. I factory resetted and it started up okay. I then found a way to fix the 16 gb issue by using a droid view guide called : "Your 32GB LG G2 Shows only 16GB Storage Space? Here’s How to Fix the Issue! " This fixed my 16 gb issue. But everything else same... Then I followed a guide to fix ESN but it demanded that the phone be rooted. So I rooted and installed TWRP. But I was not able to fix IMEI. So I then gave up I searched my issue extensively and found a thread (ON XDA) which i cant post here... But its name is: "Strange touch problem after upgrading my lg g2". There I read of other people who had the same issues. This basically happens to refurbished handsets, apparently. There where no proper fixes there. None of the people where able to fix their phones.
Some guy said that check your motherboard and install the software according to the motherboard. I opened the board and found it to be a motherboard of LG D801. No problem. I downloaded D801 software and tried installing with kdz method but it failed. And now so has the tot method. I have downloaded over 20 gbs of different software and roms. ALl of these roms where completely downloaded!! Please help me here...
Its not me only: These threads are after the same issue!!:
1. Name is: (on XDA) "LG G2 No IMEI, Touch not Responding After Update" (One person)
2. Name is: (on XDA) "Strange touch problem after upgrading my lg g2" (MULTIPLE people withe SAME issue)
I am not an advanced android guy but I can follow directions and I have adb, root, twrp, qpst set up.

Can you be more specific on the error when using KDZ and TOT? Please post a screenshot.

The kdz method just fails at 2%. But the tot method works. I installed jellybean to see if that fixed the problem But no go. Still have no touch screen and no IMEI. The major problem right now is touch screen ONLY!

zhzhou said:
Which TOT did you install? D801 or D802? I think it should be D801 because it matches your motherboard.

I agree that I should install tot of d801 . But the install fails. I tried using the LG_UP 974 dll file but that does not work too! The error is alwasys wrong model number. The TOT method works for d802 roms.
I am wondering. Should I flash a kernel of d801?

hyelton said:
Well that can happen if you flashed the WRONG model for your phone, and youd need to flash the correct model to fix it.
or 2 its an hardware issue.

zhzhou said:
You should install the D801 TOT. Here's how to do it.
1) Download D801 TOT
2) Download HxD hex editor
3) Open D801 TOT in HxD
4) Find first instance of "D801" and change to "D802"
5) Save new TOT file
6) Open Flashtool and flash the modified D801 TOT that you just created (use the LG_UP974.dll)
This should work to get D801 firmware onto your device.

I did what you said and changed the first instance to d802. Now a new error dialog appears saying: "failed previousload()"

Hi, thank you for using XDA Assist. Your devices forum is the best place to ask for help, they are the experts on your device. Start with this, http://forum.xda-developers.com/lg-g2/general/lg-g2-sticky-roll-thread-t3123148 and follow the go back to stock. Also see this, http://forum.xda-developers.com/lg-g2

zhzhou said:
It's unlikely you'll hard brick the phone. You've already put the D802 firmware on a board that you've confirmed is D801.
I had wrong firmware and subsequently lost the IMEI. I flashed the right one firmware (after modifying TOT because of model mismatch error), and the IMEI came back.
Isn't your phone pretty much useless already? I think the steps I described above is pretty low risk. You can find the answer pretty quickly by just doing it

[GUIDE] Installing and Rooting H950PR 5.1.1 from 5.0.1 10b

I caught the deal on ebay for an inexpensive Flex 2 not so long ago and, of course, the first thing I set out to do was update and root it.
The stock image ran 5.0.1, w/ firmware H950 v10b. I attempted an OTA update several days in a row, being told each time that none was available (the phone is AT&T branded and my service is through AT&T), but eventually grew impatient to get that sweet, sweet 5.1.1 action going.
After attempting to flash the 5.1.1 v11x rooted system image provided by randrew87 (here), I was greeted with a nifty little 'Security Error' boot screen and pursuant loop. Sadly, I wound up flashing the stock system dump I created following that tutorial to get back into a usable state.
Left with no other options (assuming, correctly, that I'm being impatient with OTA), I decided to try the 5.1.1 H950PR v15a firmware.
NOTE: Though I chose to flash the unrooted 5.1.1 H950PR image first, you may not have to complete this step; I'm not sure, but it's possible that you could simply write the rooted image instead.
First, I followed this wonderful tutorial by Sj12345: [KDZ] H950PR 5.1.1 compatible with ATT H950 with Video!!!
My initial plan was to write the unrooted system image and root using any of the available tutorials. Unfortunately, I couldn't get any of the tutorials to work for me as my device simply refused to allow r/w operations to /system while using the COM interface, regardless of my approach.
After a little trial and error, I discovered I could write the rooted H950PR-v15A image, provided here by Sj12345, and achieve root.
Here's how:
Download rootedsystem.img (from Sj12345's post)
Download LG Root Tools.zip (attached) and extract to a folder
Copy to the root of your internal sdcard via means of your choice (I used MTP mode and Explorer to drag and drop)
Power off your device
While holding VOLUME UP, insert a USB cable.
Open a Command Prompt window where you extracted the archive (easiest way is by holding Shift then right clicking within the folder > Open Command Prompt Here)
Double click ports.bat (included in the archive). Find the diagnostics port (in my case, COM4)
Type the following:
Code:
Send_Command.exe \\.\COM4
(replacing 4 w/ your com port)
You'll be greeted with a '#' prompt, terminal-style. From there, issue the following command (thanks to randrew87's thread):
Code:
dd if=/data/media/0/rootedsystem.img bs=8192 seek=53248 count=534528 of=/dev/block/mmcblk0
The operation will take a couple of minutes. Once complete, you'll again be greeted with the '#' prompt.
Type LEAVE (all capitals), and hit enter. Your phone will reboot and have a clean, rooted image installed.
Profit.
This guide is obviously very specific, requiring H950v10b 5.0.1 firmware on an AT&T flex 2, no OTA availability, and a myriad of other issues (such as /system being readonly). My hope is that this will aid others who don't fall exactly into the parameters described in existing tutorials.
Thanks again to randrew87 and Sj12345 for their great posts and work; this thread is merely a slightly different approach to their pre-existing methods. They did the work, not me!
Hope this helps someone!
Regards
Smith

Any reason to go with h950pr instead of Ota 5.1.1 or simply just out of frustration of waiting? I'm asking cause I should get my att flex 2 tomorrow.

PR rom does not have all of the AT&T bloat. However, the main drawback that I'm aware of is that there is currently no way to go back to official AT&T. Seems everyone who has tried to do so has ended up with a bricked phone. You may also run into issues trying to get warranty honored once you move off the official AT&T version. So.. caveat emptor and all.
Most folks who really want the 5.1.1 OTA have managed to do so by laying down the minimum amount of cash for an AT&T gophone plan then getting on the horn with AT&T's tech support to have them manually push the update through.

Hi smithisize, thank you for your guide A very basic question, how do I know which version of root file to use? I just check in About Phone > Hardware Info and it said the phone was LG-H950.

Smithisize,
Thank you for the guide. I have a question.
My H950 has H950v10d 5.0.1 on it. I am just guessing that it would work for any 5.0.1 version.
Is this right?
Thanks again,
MB

Same here...
As Meatbag_1 written, I have the H95010d release witch rom we take???

Yes it will work for atnt g flex2 on atnt firmware 5.0.1 all subversions

Isn't the latest software version for the US h950 the "v11x" version? Is it possible to flash that instead of the PR firmware?

No
Only OTA from AT&T
No flash

I tried rooting my newly flashed 5.1.1pr with this method and got authentication error 11. I had to reflash to get out of the boot loop. What am i doing wrong?

Thanks man. How can i root it in the first place?
I was trying HERE but i do not know which to dowload, if H950 V11X or H950 V11Z ... can you help me with that?

H950v10d 5.0.1 not rooted. Tried method from OP using H950PR 5.1.1 rootedsystem.img. Now I am stuck at Security Error bootloop. Where to go from here?
Nevermind... Phone started non stop bootlooping with no way to shut it off. So, I smashed it to bits.

For Android 5.1.1 PR (Puerto Rico)
First Flash the KDZ file from here: http://forum.xda-developers.com/g-flex2/general/kdz-compatible-att-h950-t3180847 using LG Flash Tool. I use Build 03/07/2014 Offline with modded hosts file.
Then download the Rooted H950PR-v15A image file from the link provided and continue with the guide.
btw: thanks for adding; you type: "LEAVE" in caps. No other guide seemed to mention that and when I did, it was the only time it actually rebooted my phone..:good:

I was able to get to download mode, but it would just go into bootloop after entering download mode. I have another on the way, so hopefully things go better this time. Will try the method posted above.
Can you send me a link to download "LG Flash Tool Build 03/07/2014 Offline with modded hosts file?"
thanks

Your can download it from here:
http://forum.xda-developers.com/showthread.php?t=2797190
I ignore the warning about the kdz having to be in the flash tool directory. I just browse to the location I downloaded it to, never fails.
And about the hosts file, this version doesn't seem to need a modded hosts file as it won't try to connect. That was sth I had to do from an earlier version a long time ago and forgot.
Fyi: I soft-bricked my phone like many others having the same security error because of tring to install the rooted system image file for 5.1.1 over the top of 5.0.1. And to reboot from download mode I had to hold all three back-buttons.
To install Xposed framework follow this guide: http://forum.xda-developers.com/g4/themes-apps/guide-installing-xposed-locked-t3181593 but USE Flashfire 0.24 or earlier as the latest beta version won't flash sh*t on this phone (or the G4)
If you need detailed instructions let me know.
Good luck!
PS: I bought the AT&T version(5.0.1) for the 3GB of RAM but I live in Australia so couldn't get the 5.1.1 OTA which is why I had to do this way, but apparently if you flash the 5.1.1PR kdz over the 5.1.1 AT&T OTA update(just to avoid AT&T bloatware) it will brick your phone.

so i just purchased the the g flex 2 much like yourself and i have everything ready to go. My only concern before doing so is what to do after the soft brick. Once you reboot from download mode is, doesthe phone start normally? or is there an extra step since you talked about USE flashfire
PS. i dont care to root the phone or is it necessary for this all to work?

Updated H950 5.0.1 ATT to H950PR 5.1.1
had the lg drivers which i downloaded using the lg suite from the LG website ( i originally tried to update my phone using this method...didnt work obviously so i came here)
Used lg flash tool 2014 as provided from this forum.
Placed H950PR15a_00.kdz in the place where it asks in the tool
followed the guide, i had the phone in debugging mode and it was just on my homescreen unlocked, phone shut off restarted into download mode and started the firmware update, phone itself reset at 100% ( keep it plugged in)
Lg flash tool was still going at this point it was around 90%, phone was resetting when the lg flash tool hit 100% and then crashed ( had a panic attack really ) i kept the phone plugged in and it reset to the lg boot screen
Leaving it plugged in , in spanish i saw that it was optimizing my apps, went to the tutorial within the phone and it resarted again... so i started having another attack, i then saw the boot screen claro at this point i unplugged my phone and it is now on 5.1.1 h950PR i have not rooted the phone before hand it was stock from ATT.
Thought i put my experience in here with this phone in hope to ease some tension. it was easier than i thought even though the tool crashed at the end, phone had already accepted the KDZ at that point

How to unroot Sprint LG G Flex 2 on ZV6?

Ok so I purchased a brand new Sprint G Flex 2 on ebay http://www.ebay.com/itm/221950977883 and to my surprise it was already rooted with firmware ZV6 so now I can't take OTA updates since it stops updating halfway through the update and the green Android guy lies on his back with the "error" message. I already did the full unroot method using SuperSU but still a no go. Before I send this phone back to the seller I want to make sure if there is any hope in fixing this issue and allowing the updates. I also downloaded the root checker app to see if root was gone and it states root is not configured correctly. Not sure what that means as I used SuperSu to fully unroot. Any help would be appreciated as I only have 14 days to return this device to seller but I do not want it rooted as it prevents updates through Sprint. Thanks.

Those who want to unroot and go back to stock ZV6 (so they can get the OTA ZV9 update) should be able to use these "dd" flashing instructions:
http://forum.xda-developers.com/g-fl...5-1-1-t3169212
along with the stock ZV6 firmware image from here:
http://forum.xda-developers.com/g-fl...k-img-t3217089
However, you will not only lose root. You will also lose the SIM carrier unlock. After reverting your phone to stock, your phone will be carrier locked to Sprint. That's because carrier unlocking is done by altering some "node db" system files.
After applying the OTA update to ZV9, you will have to redo both the carrier unlocking and the rooting of your phone. It's doable, but it's just something to keep in mind.

Thanks for the info. I have one question though. I did the unroot method using SuperSU and was wondering if that will not be enough to get OTA updates once I get my Sprint SIM card installed. From my knowledge if the system files were messed with OTA updates won't work correct and in this case you stated that carrier unlocking involves altering node db system files. So even if I did the full unroot method using SuperSU the altered files would remain correct?

I believe you are correct. Since the eBay seller altered some system files (that's probably why he rooted all these phones and installed SuperSU) to achieve the carrier unlocking, the OTA update for ZV9 is failing. Even if you unroot and delete all traces of SuperSU, I think the OTA will still fail. The update script probably does some sort of checksum verification of all the Android OS files before proceeding.
Also, I don't think you need a Sprint SIM in order to do the OTA update. I believe the OTA comes from LG's servers, not from Sprint. I've heard of people getting the OTA update even if they are using an AT&T or T-Mobile SIM. As long as your phone has data (cellular or Wifi) I think the OTA will download. But as you've found out, it won't install unless you go back to stock.

From the guide you just have to follow
1. Download and extract the stock img.
2. Transfer it to the root of your internal sdcard (images are usually named ZV6system.img) avoid moving the complete zip.
3. Put your phone in download mode (you can figure this out)
4. Use the dd command for your variant in your case LS996, just change the name of the ¨rootedsystem.img¨ to the one you downloaded.
Aaaaaaaaaaaand you´re done :good:

I did everything in the guide and phone even rebooted when I typed LEAVE after the "#" prompt but I still can't take OTA and Android guy falls on back with "error" message. I have another question when I click in the status section in the About phone settings and I scroll down to Brand it lists Chameleon. Is this normal?

Did you download the stock image from the forum I made?
Cause if you flashed your current system.img then you flashed the rooted one.
Make sure you are using the Send_command on the diag port of your phone if you arent doing this then you wont flash correctly and phone will stay rooted.
And yes, when the phone hasnt been unlocked internationally Chameleon is the ¨Sprint stock way¨

I did flash the ZV6 stock image from your forum http://forum.xda-developers.com/g-flex2/general/return-to-stock-ls996-stock-img-t3217089 and I used the send command to port 5 because that is where the Diag port is when I double click the ports.bat file. I actually tried this method twice and I still am not able to update without error. Maybe I do need a SIM card installed and will try it tomorrow when I get my SIM delivered from Sprint. Thanks a lot for the tips though.

Thats kind of weird you know, I OTA updated my phone even after international SIM unlocked.
How long does the flash process take? If it takes less than a minute then its not doing things as it should.
Did you enable USB Debugging before flashing?
Have you tried to Factory Reset after flashing the stock ZV6 system.img?

I do have USB Debugging enabled. The flash process takes around 1 minute and then the # shows up indicating it finished and then I type LEAVE and phone reboots. I even tried the factory reset after flashing it with the stock ZV6 image. This is very interesting but I will wait until tomorrow to make a decision on whether to keep the phone when I insert the SIM and see if that helps any. Thanks Alex for all your help.
I forgot to ask this but do I have to type the commands or is copying and pasting ok.

Well it depends on how did you copy/paste the command.
To flash the ZV6system.img it should be like this:
dd if=/data/media/0/ZV6system.img bs=8192 seek=58368 count=522240 of=/dev/block/mmcblk0

Thanks for your patience with me. Do I have to run both the dump and flash commands as I have only been doing the flash command and maybe that is the problem?
is this how the commands should be typed?
Dump command:
dd if=/dev/block/mmcblk0 bs=8192 skip=58368 count=522240 of=/data/media/0/system.img
Flash command:
dd if=/data/media/0/ZV6system.img bs=8192 seek=58368 count=522240 of=/dev/block/mmcblk0

I'm in a similar boat w/ a slightly different issue. I bought the same phone from the same guy and have not been able to get it to activate on Sprint at all. Well, it "activates" but then it errors on updating the PRL. I have LTE data, but no call ability. It is very strange.
So far I have:
Unrooted via SuperuserSU app that was installed
Taken it to Sprint store and had them do everything they could (while being condescending about buying a phone not from them)
Played with every setting I can find
Factory reset many times at many stages
Flashed to the stock ZV6
Installed 2 OTA updates (now a third is coming through)
And every time, I get a your phone has been activated message, followed by trying to update the PRL and failing, leaving me in the same place I was to begin with. I'll try it again after this latest OTA update I'm getting, but I'm running out of things to try and I'm extremely frustrated lol. Anybody had the same problem? Any ideas? Anything? I don't know if maybe it's just a defective phone... sigh. Thanks in advance for any help!

Did you get a new SIM card from Sprint or did you use an old one because Sprint told me they need to send us one that has been programmed for the LG G Flex 2. On another note when flashed the stock ZV6 image did you send both the dump and flash commands and did you have problems getting the updates before you flashed to stock. Thanks.

I picked up a new one at the Sprint store. I would hope they knew which one to give me haha. I only used the flash command. And yes, I had the same issue as you did with getting the updates before I flashed. No problem with that now, 3 updates later I'm on ZV9. Now if I could just get the phone activated...

Restore v20 to 100% Stock (!!even for bricked devices!!)

This is a simple method to restore your v20 to stock, I have tried with my bricked H990DS with wrong bootloader flashed.
1. Download .kdz file for your v20 model from the following links. Currently v20 models available are:
F800K, F800L, F800S, H915, H918TN, H990, VS995, H990N and H990DS
H990DS https://lg-firmwares.com/lg-h990ds-firmwares/firmwares/
H990N https://lg-firmwares.com/lg-h990n-firmwares/firmwares/
https://lg-firmwares.com/
2. Search, download and install LGUP ( LGUP_Store_Frame_Ver_1_14_3.msi ) and a file called LGUP_common.dll
2a. Copy the LGUP_common.dll to C:\Program Files (x86)\LG Electronics\LGUP\model\common (May need to modify folder access right)
3. Search, download and install LG Driver ( LGMobileDriver_WHQL_Ver_4.1.1.exe )
4. Completely Power off the v20 ( or to remove and put the battery back )
5. Plug the USB end of sync cable to your PC
6. Press and hold "Volume Up"
7. Plug in the USB-C end of sync cable to the v20. The phone will enter download mode (or Firmware Update). Now you can release the "Volume Up".
8. Run LGUP. The program will regconise the v20.
9. At the file path, click "..." and chose the .kdz file
10.Choose "UPGRADE"
11.Click "Start" and wait until the process is complete.
Now we have a safe method of restoring bricked v20. Hope developers can start trying to root without worrying of bricking the phone.
This method is verified on my H990DS. If anybody successfully flash using this method please let us know. Thanks!

Great thread! Just want to add a quick PSA for this:
This may update your phone to the latest firmware which may patchs the current recowvery exploit. While this will unbrick your phone, you should make sure that you have the a firmware below 10i (w/o patch) to flash. If you still have access to TWRP and don't have a 10d firmware for your device, use this instead.

Thanks for the reminder. Actually it depends on what .kdz is available. For H990DS there is actually v10b firmware for download. So after I flash using this method the dirtycow exploit is still there. Take a look at the filename of the .kdz (e.g. 990ds10b_00_OPEN_TW_DS_OP_1125.kdz is v10b released at Nov 25) Seems that versions below v10i are still ok for dirtycow.

Ahh! Nice! Hadn't considered that. I'll update my OP

Darn. Got my hopes up. No VS995 in the list. No T-Mobile and no Sprint either. I don't need it....yet...but I would love to have a restore method for my VS995. Though I've had an LG G3 rooted and flashing custom roms, kernels, and mods for 30 months and never once restored it to stock so perhaps the V20 will be the same

are you using uppercut for the model .dll in LGUP?
i have tried this method a few times over the last week, no luck. but i was pretty rough with my phone to be honest, no backup and tried all the other v20 variant roms.
right now LGUP detects my phone as a US99610D so will not flash the H990DS firmware, tried to edit the kdz in hex editor for name value but it detects the kdz as corrupt now. any experience with this?

I did not use uppercut because anti-virus reported it detect trojan when I use the program.

so you found a v20 dll file? do you mind posting a link? or how did you get past LGUP picking up v20 as unknown device? or was this not an issue for you?

The LGUP first did not detect the device and asked for driver. So I installed the driver as mentioned in OP. After that i was able to flash the phone with the kdz file.

What do you mean?
If this method worked for you & a few other users, it should probably become a sticky rather than closing the thread...
Unbricking a device & restoring to 100% stock is an important feature to most, so if a few users are having issues we should probably help sort out those issues rather than abandoning the thread...

don't close it off, if it worked for you it should work for others that haven't broken the phone quite as much as me (boot, recovery, aboot and system changed).
the dll looks to be a requirement, perhaps uppercut worked for you prior to you AV killing it. i used it despite the AV alert.
so that part works fine, my phone is detected as version US99610d (files used during root attempt) which prevents me running the KDZ with "Error: KDZ file is invalid. US996 -> H990"
i tried to edit KDZ file to change version from H990 to US996 but this just corrupted the file.
i edited the model in build.prop of a rom and flashed it but it failed to make a difference to LGUP.
in a last ditch effort i restored aboot.img but phone is still detected as 996 instead of 990. but now no more twrp or unlocked bootloader.
any idea what LGUP reads the version info from or how to force it to run a KDZ from a different model?
