[Q] Need help with my E-988

I hope someone can help me.
I bought an LG Pro E-988 which is already rooted and have a nightly CM11 installed.
I saw the LG Flex Rom and tried to install. I hit an error (Status 7), so I restored my back up. It booted correctly and decided to install/run the LG Recovery and Freegee apps as I suspected that the error (Status 7) was because I didn't install the apps before the LG Flex ROM.
After I run FreeGee, I restarted in recovery and tried to install the ROM but still same error (Status 7). So I decided to restore my back up again, but this time around, the boot is not pushing through. I'm stuck in the LG Logo.
Has anyone experienced this before and maybe you can help me to fix my phone.
I admit I got a bit excited rooting and flashing custom ROMs again after 1 year of hiatus.
Thanks in advance!!

Nothing to worry about. Here is a pinned post where you can find all the information you need.
Just download your kdz from here and follow the steps from this post
Download kdz, install lg flashtool, lg drivers, after turning off your phone, press volume up and down together and connect your usb cable to get into download mode, then follow those pictures in that post to flash the kdz. You will be back to stock.

Thanks a lot man :good:! Although, I'm stuck with 'Connection error' in the FlashTool. Is this normal? I tried again and again more than 20 times but I'm getting the same connection error.
Also, earlier I was still able to go to recovery, but now even if I press the power button it goes straight to the download mode.
Hope you can help again.

You cant get out of download mode? did you try volume down and power button together for 5 secs? And btw what error are u getting on flash tool? its not detecting your phone? Did you install the mobile drivers?

The error was in the LG Mobile Support Tool (sorry to in the Flash tool). During the upgrading of the phone it always give the error - 'Connection to server failed. Try again in a moment'
Also, if I try to turn on the phone it will not boot but go straight to download mode.

Did you remove the battery and put it back in? And it still goes to download mode? Try starting the phone pressing Volumedown+power key for sometime or you could try Volumeup+Homekey+Power to boot into recovery and try restoring backup or flashing some other rom and see if you can get out of boot. I really don't know why you are getting that connection problem. I got stuck at boot a couple of times and followed exactly what was given in that post and reverted back to stock. I guess some of the senior members will help you here. Meanwhile ill see if i can search a solution for that connection error, i haven't faced that yet so i really don't know the fix. There is a second TOT method given in that post, that might help.

Yup, i tried removing the battery. Also tried different key combos to boot but it all goes to the download mode, with the small with box in the middle.
I also tried the option of going straight to the LG mobile support tool (not the LG Flash tool). But the same server connectiom error.
Thanks again for the help.
Hope other members can help me too.

Since I'm not able to do recovery using the KDZ file. Can I use the TOT file?
I have E988 Singapore version, but the last ROM installed was with a CM11. And in the Phone details it shows E980.
Will it work or will it just make things worst?

I haven't flashed using TOT method so i cant comment on that. I heard few people had trouble using flashtool on windows 8, are u you using windows 8? maybe try the kdz method again from a windows 7.

Yeah, I read that also. I used a windows 8 pc previously, that might be causong the connection error. I will try my old pc and hopefully it will work.

[Q] LG Optimus G Soft-Bricked? Please help me to recover my phone

Hey Guys,
First post and i already got a problem because i messed up very much
I used to have Cyanogenmod 11 on my Optimus G, but i got several crashes and i wasnt completely fine with it so i wanted to try something new. So i updated my bootloader from CWM to TWRP and wanted to flash Artmod 5.2 Rom. I was a bit fast with my wiping, so i accidentally wiped the whole phone, so that everything was gone: Cyanogenmod, new Artmod rom i wanted to flash just everything.
I read a bit and thought it shouldnt be a problem then to just sideload the new rom, which i tried to do. I used adb sideload to put Artmod on the phone, everything was fine, flashing went through but i got stuck at the LG boot logo at the start of the phone. I waited like 30 minutes and nothing did change, so i thought something was not right.
I then just wanted to go back to cyanogenmod, tried to flash that through the adb sideload procedure but i got an error which said "error executing updater binary in zip 'tmp/sideload.zip'".
I was kinda thinking something really messed up so i tried to revert the phone to stock rom with the correct KDZ file i searched with the tool linked in the FAQ, everything downloaded but when i tried to flash the KDZ it gave me an error like this:
"12:03:59 Launching SW update
12:03:59 Unpacking KDZ
12:05:10 KDZ file extracted
12:05:11 Extract file error
12:05:13
===FINISH===="
So i searched the forums again and noticed that it should be a problem with the KDZ updater tool because the KDZ file was too big to get flashed properly. I wanted to try the LG Flash Tool 2014 then which is provided here in the forums and should work, it extracted the KDZ file, then opened the LG Mobile Support Tool to flash the file on the phone but there i start to get errors again, it either said that i am already on the correct up to date software version or that i need to disconnect the USB cable, remove the battery, insert it again, restart and try again.
I used several tools for that, i even tried it with an offline method that i found in a german forum, but every method got me the same errors, so i couldn't even go back to stock anymore.
I once tried to flash Cyanogenmod then again when i realized that the error message also told me "This Rom is for a "E975", this is a "GEE"" which i did not completely understand because it should be the total same? I edited the Updater-Script in the Zip file of the rom then and removed the part where it checks for that (1st line actually), then the rom did flash properly, phone started to boot (Cyanogenmod Boot Logo was shown) but when the boot was over i got the message:
"Type Password to Decrypt Storage" with a keyboard to enter the password. (I did never set up any password for that).
Now i am completely confused what i can do the recover my phone, either to stock or just to another rom, every method i tried did not work and i dont have any other ideas.
I can go into Fastboot, Recovery and Downloadmode, but when i tried to wipe again in Recovery it says that it cant mount my data mount point (probably because the storage is encrypted).
Somebody told me to do a hard reset with the keys "Volume down and power" which i tired several times, but everything i get is just the Google boot logo and then happens nothing or i get the Google logo, then the LG logo but after that i get stuck again, I cant seem to go into the "Hard Reset" menu which i should get into with that keys.
Anybody can help me what I could try or got a solution for this? I would be very thankful. I don't wanna loose my phone

Flash Tool 2014 works great for me every time, so try it again. Make sure you disconnect from the Internet before running it (yank out your LAN cable, or disable your WiFi), so it doesn't attempt to connect to LG servers. And don't forget to put your KDZ file in the same directory with the tool. It should go through just fine. That's by far the easiest method to revert back to stock, to get you to a clean starting point.

Umm... No, they are not the same. E975 is "geehrc", and there is no such OEM ID as "gee". There are many different OG variants. For the cross-reference between the models and OEM IDs, you can look here. Generally, you should stick to the ROMs that are designed for your model, unless you know exactly what you are doing, when trying to flash a ROM from a different platform.

Well i tried Flash Tool 2014 again and seem to get the same error that wants me to disconnects as it stops at the same position like it always did, also doesn't matter if I am connected to the internet or not, everytime it doesn't run through. This time I couldn't even read the stuff that was written in the LG Mobile Support tool because it only shows "????".
Heres a Screenshot:
The settings i made should be the right ones I think, the phone does get recognized by the computer when i plug it in because of the sound that windows makes.
I clearly dont't know what I can try anymore...
And according to the roms: well i only used roms for the E975, which is exactly my phone model, thats why i was wondering about that error message i got
Artmod is for E975, the CM11 was for E975, i even tried Mokee rom but i always got same error messages...

Nobody got another idea? I really am confused because if i can enter downloadmode and recovery there should be a way to get my phone back working.
Anybody knows where i can get maybe some older KDZ Files to go to 4.1.2 Stock rom and try to flash these?

I don't know why you are seeing "???", but here is a couple of things regarding the settings, based on your screenshot:
1. Type should be CDMA (yours is 3GQCT).
2. PhoneMode should be DIAG (yours is CS_EMERGENCY).
3. I would suggest using CSE Flash for a full format (you are using Normal Flash).
Remember, this is a hacked tool, so the settings might not make perfect sense, comparing to the original ones. Just try following the instructions in the OP of the Flash Tool 2014 thread. Like I said, works every time for me...

I just tried the settings you told and used CSE Flash which worked out really well.
No i am back to 4.4.2 LG Stock rom. I think the root is gone now, but one thing i wanna ask is if my bootloader is still unlocked and custom recovery is still on it?
Anyway, thank you so so much! I appreciate your help! Thank you!

Glad to hear you are back in business. After flashing KDZ, the root is definitely gone, your BL is locked, and the recovery is stock. You will need to do all the necessary steps again: root, unlock the BL and flash custom recovery.

LG G4 boot loop into TWRP

Hello everyone,
yesterday I flashed a new Cyanogenmod 14 nightly (12062016) for my G4 from earlier nightly in TWRP. After reboot the phone keeps going back to TWRP and I can't seem to get it to boot to system..
I tried factory reset, reflashing back to old nightly, flashing stock.. but nothing seems to work.
Also tried doing this in the TWRP terminal:
dd[space]if=/dev/zero[space]of=/dev/block/platform/f9824900.sdhci/by-name/fota
Didn't fix the loop, I guess because it wasn't the OTA update that caused the problem in the first place.
If anyone has an idea, I would greatly appreciate the help!
Thanks.

If you can reach download mode you could try reflashing back to stock then starting again.....Hope you get yours fixed - Sorry to say this but mine did a very similar thing only 24 hours before you posted!!! Only mine was on stock FW and was in use at the time - I've now had to swap it as valuebasket who sold me the phone have ceased trading. If yours is a UK model you may be able to get it replaced under warranty - believe that LG guarantee their phones for 2 years and a ruling by the European court said that flashing a custom rom doesn't invalidate any warranties.

I have the same exact issue, I also flashed the latest CM14 nightly and cannot get the device to boot any rom.
I have even tried flashing stock rom but I get the same problem.
From what I have read, the bootloop issue happens once the device boots but I don't seem to be getting that far.
Any ideas?

Ran into the same problem 3 days ago. This is the first time I have encountered a non-revertible issue in 3 years as a cyanogenmod user. This changes my opinion on how safe it is to make use of a custom ROM. I tried to wipe everything, reinstall TWRP, change TWRP with another recovery, reinstall a safe NAND backup of mine.....nothing.....it went into boot loop. Before I read this post, I was convinced my phone encountered the infamous G4 bootloop problem.....now I see there are other examples, so it shouldn't be the case. Long story short, I had to check my device in at the LG assistance, with 25 days as time forecast.
The guilty nightly was 20161205.
I have never seen anything like this...

This has solved it for me - I installed LG Bridge and flashed the factory firmware using the tool. Now it seems I'm back on stock but at least it's working.

got mine working. I had to install LGUP and flash stock ROM. Once flashed I installed CM14 and I am back up and running again.

I tried LGUP but it could not recognize the device while this was looping.....a bad experience......

I have the same issue. My phone was updated to 20i via the original stock firmware, then I put twrp 3.0.2-0 and cyanogenmod on. I did a cyanogenmod update from within cyanogenmod, which just booted into twrp, then I manually installed the update zip that cyanogenmod had downloaded, then it always boots into twrp. I wonder if initiating the update from within cyanogenmod was the cause. The phone is not detected by LGUP or LG Bridge. I've tried this on a win10 machine, and a win7 vm from linux. I have access to twrp, and download mode by doing the reboot into bootloader from within twrp.
If those people who have fixed this could give more details about how they did it, that would be good. What exact steps did you take? What stock firmware version did you have before installing a custom rom? What OS version were you using? What twrp version?

Well. Mine got stuck in bootloop for the second time today. What is going on? In between the two bootloops I had one good update with CM. Using TWRP 3.0.2.1. Steps to reproduce failure: updating CM from within CM, it autoreboots into TWRP and after that nothing happends, no autoinstall. Then after a manual install of the new CM the bootloop starts.
Resolve the problem:
* Install LGUP 8994 DLL Ver 0 0 3 23, Install LGUP Install Ver 1 14, get the latest KDZ
* Get the phone into download mode with usb cable and after that in firmware update mode
* Startup LGUP and choose refurbish and select the kdz file.
* After that you can boot into your stock LG firmware again, reinstall TWRP an CM. If you want so.

Read that it is advised to manual update cm from within TWRP. TWRP will get an update in the future to solve this bootloop problem.

I second that. Same issue and neither LG Up nor LG Bridge will recognize my device. Looking in device manager there are no serial interfaces. Do I need a special driver that provides a com port for a phone in recovery or fastboot mode?
---Edith 2016-12-12: Found a solution for my issue:
The phone has to be in _download_ mode, not in recovery or fastboot. After realizing that I have to boot the phone in a different manner, it will be recognized by LG UP.
Here is how to boot the pone in download-mode:
- Power off your LG device.
- Press and hold Volume Up button.
- Connect your device to PC with a USB cable while holding the Volume Up button.
- You’ll boot into download mode with “Firmware Update” written on top of the screen.
Now everything is fine again.

I was able to get out of that by also wiping by-name/misc. Don't do that, though, because then your wifi mac address will get messed up and you'll spend all day looking for a permanent fix for that.
I suggest reflashing a stock KDZ using LGUP, as others have said. You can get the usb drivers from LG Bridge.

I will release a fix for that soon. Check the twrp thread for updates on this.

Hi
I also have this problem
I installed cm-14.1-20161201-NIGHTLY-h815 successfully and was running it for almost 2 weeks without issues, today I updated to cm-14.1-20161213-NIGHTLY-h815 from cmupdater and I have been ending up in recovery every time I rebooted.
I tried flashing the latest cm recovery and reflashing the rom, with full wipes but no luck.
Full steps of recovering would be appreciated (for example, there are comments about flashing the latest stock rom, but a link to this rom would be helpful)
Thanks

Good news regarding this:
http://forum.xda-developers.com/showpost.php?p=70082901&postcount=213
The above will fix TWRP bootloop issues as well and I also released a first h811 version which should allow installing CM etc as it should.
Keep in mind that this is a BETA and not an official TWRP release.
Please report back in the above thread!
.

Does your twrp beta really fix the boot loop even it is already happening. What do I have to wipe? I have not managed to get out of the boot loop despite intalling it.
Is using using LG Up to flash to the stock rom really the only option?
Edited 2017-01-25 2:45 pm:
Well, sometimes you just have to be patient. Powered down the phone and when th H815 restarted CM did boot. Great. :good:

Hey, I just want to share a small detail, possibly a fluke that helped me overcome the bootloop.
So...I started with a fresh, stock H815, I don't quite remember the firmware version..it was something like version "20g"..
OK, I looked up several guides and tried to get the newest stable versions of each tool. I went through with the official bootloader unlock, then moved on to rooting: Kingroot didn't work for me so I went on installing twrp in fastboot mode so I could afterwards install supersu and root.
I got there eventually but first I was stuck in bootloop - kept ending up in twrp interface. I found the 2 dd commands but those didn't work for me as the msm_sdcc folder did not exist, but instead there was a "f9824900.sdhci". Tried to overwrite this one ...but as others have stated as well, it didn't work.
At that point, I had nothing to lose, I was starting to accept that I had soft-bricked my precious G4 so..I went on installing the DU 10.6 7.1.1 rom and the stock gapps, wiped dalvik, rebooted and held my breath...not literally
About 12 minutes later, after an endless red, spinning logo, my shiny ping pong paddle showed me a different screen, a fresh start welcome screen .
Almost 24h / 10-12 reboots (twrp included) / 70+ apps installed and removed later, the new OS holds around 2G ram average, a bit better battery life, smoother transitions, flawless navigation, flush streaming over both 3G/LTE & 2.4/5 G wifi.
FYI the reboots were intended, wanted to see consistency in boots - we're in the green . Now testing long term stability with moderate/high usage.
There is 1 aspect I noticed, there are a couple of contexts when the interface burps (several menus, various situations, never in apps) and resets back to homescreen...but I think that's more of a launcher topic than an OS one.
Other than that, so far I'm happy with the mod.
Hope my experience helps others that might be in the same spot I was or at lest boosts their confidence to try out a decent idea they might be pondering.

Secure booting error after Hidden menu test

Hello,
i dropped my phone last night and at first boot phone clock changed and i could not connect wifi. i tried to connect wifi today but it did not worked. Thats why i opened hidden menu by using *#546368#*855# test my phone if there is a hardware problem or not. i clicked first option then second option my phone got reset but i got Secure booting error after that and it stuck. Then i opened twrp by using factory data reset option. i got backup of my data from twrp menu.
What should i do now?
Notes:
- i use twrp + android 6.0 rooted firmware
- i dont know if can can install apk since i cant open android system
- i dont want to install stock rom by a pc because i think i will lose all info on phone and ont be able to get them back without twrp.

It would be better not to flash those kdz files.

It would be better not to flash those kdz files.

thanks it worked in second time now i can enter download mode i am flashing with lg flash tool. the problem is i could not install twrp before. i tried 5 roms + autorec, twrp manager and twrp offical app. and all resulted failing to open clock work mode. now i will try with D85530B_00_1217_32G.kdz
i have twrp backup in my sd card that why i am trying to boot into twrp for more than 24 hours. i hope i can do this. i winn never use eutorec i will use offical twrp app next time.
i can open android but i cant open twrp i got error boot vefication failed. i can use phone like that but i want to get my backup. if i cant i will have to install apps one by one and i will also lose some files, contacts, data etc.

I Bricked and Unbricked my day one V30 in one night (How to not be completly screwed)

I picked up my UK V30 H930 yesterday all fine and saw that LG have unlocked the bootloader on my model so I went ahead and tried it along with trying the alpha TWRP build
So I thought id write about what went wrong and how I recovered from it.
I made the mistake of letting the phone auto update to 10v software verion before I did this. As I had 10f on before when I bought the phone.
I went to load in all the software needed to unlock the bootloader and proceeded to do so but in my haste of the user data being wiped taking a longer then I thought it would I unpluged the phone to try "fastboot flash unlock unlock.bin" again . No such luck already unlocked. It booted back in fine so I thought everything was ok but that was the moment I thought could have caused my entire night to be ruined.
I thought with the bootloader saying it was unlock it was now fine to flash TWRP on now so went to do that and discovered it would no longer boot into the rom anymore coming up with the LG V30 Logo and just staying put. Thought it must be my 10v software version messing it up. Ok ill try to flash a 10f stock kdz. After about an hour or so of 'Finding my feet' with the phones boot methods for download mode, Fastboot and recovery I found that twrp was being strange with mounting the phone tried otherways eventually got the phone talking to the pc by using uppercut with LGUP and having the phone in download mode and the port com channel in device mananger set to com 41. After about 4 tries of flashing KDZ's to the phone it would just come with a "erasing" circle and proceed to get stuck on boot logo again so I messed about with .dlls and tried to other methods. Still nothing.
Now I tried LG Bridge's "Update error recovery" and I was actually talking to the phone for the 1st time so i let it do its thing which took well over an hour to download the kdz file. "Fine just work please". it got to the updating stage at 5% and froze and the phone being in download mode hadnt done a thing. I tried again but still nothing. Eventually now at 6am and having been up all night I went to give up but I manged to get it on to fastboot mode and by chance came across "flashing lock_bootloader" tried and it and it locked tthe bootloader back up (this thing of LG saying it cannot be undone must be rubbish?) now before I tried anything I rebooted the phone . IT BOOTED! onto the fresh 10v KDZ i had installed on it but before anything I wanted to see if it would now run with a unlocked bootloader on its own with no TWRP installed. It works! Now i just need a method of rooting but im now ready at least.
Hope this helps anyone with simular troubles.

Also had some trouble yesterday after trying out some Magisk modules.
On reboot it sometimes got stuck in the LG V30 screen, and sometimes even the bootanimation came up, but it didnt finish the boot lol
Only installed and adblock btw, and tried the Xposed module. Uninstalled that again btw. Now only using Adblock.
Phone also seems to need Power + Vol- to force shutdown for me, not only Power like other phones. Also didnt manage to find a way to boot into recovery when the phone is off, only found a way to get into the factory reset screen ?
sadly i dont have a working sdcard currently (my 3 year old 128GB one is read only for some reason, atleast changes dont get applied), so ill wait for a new one to mess around more ^^
Also working on a LOS14.1 build atm (it compiled, but didnt adapt all parts of thr device tree yet, and no idea if i have all vendor files lol)

nope, doesnt have one. Neither windows nor Linux fail at writing on it, or when deleting files, but as soon as I re-insert the SDCard all changes are reversed. Formatting doesnt work anymore, unknown error. Tried that in Windows, Linux and in the Phone (Androids formatting crashed, TWRPs produced an error after it timed out)
