I rooted my LG Optimus G Pro 4.4.2 via TowelRoot, installed SphinX, FreeGee, and installed TWRP recovery. I then flashed Cyanogenmod 10.2, and it (seemingly) worked well. However, I seem to have lost the ability to call others and recieve calls, but texting works, and I am disappointed with the battery life. It seems to not support reading the tilt of the phone, which I use with some of my paid for games.
So I flashed Beanstalk, and the installation seemed to work well, but on the reboot (after I had wiped before install and after, before rebooting) it gave error messages saying google services closed, and wizard closed. It gave me the option to report on both issues, but each time I closed one error window, the other would pop up, like in an endless loop. So, thankfully, reboot into recovery was a power button option in that rom (wish they all did that) and I then flashed back to CyanogenMod10.2. So I then decided to update Cyanogen to 12 via the built-in upgrade, and it also did the same thing, giving the same error messages in a continuous loop. So I finally was able to power up into recovery (for some reason, it seems to not work every time after shutting the phone off).
I am wondering if I can just flash back to the stock, and then debloat, or, better yet, can I just flash 4.1.2 to this device (I don't know if it ever had that OS) then root and debloat, as I do wish to use my wiimote. I have looked at the various methods to return to stock, but they seem to be quite confusing, as I don't read text-type very well, and most of the descriptions are typed this way. I would appreciate any assistance with getting these issues taken care of.
supersu unroot
Sorry for the double post, but I read that using supersu to unroot would brick the phone. Will this method simply return the phone to stock, or will it damage it?
Ok, so if I am understanding this correctly, to return an e390 to stock, you:
1. download and unzip the lg flashtool
2. download and install current lg drivers
3. download the dll and stock image
4. put phone into download mode and then plug into computer
5. run flashtool + make sure device manager port is com41
6. select dll and firmware, and finish
7. flash the modem-can this only be done with root?
What is step 7? Flash what modem?
Hi guys,
(Samsung S4 Mini GT-i9190)
I could really use some help.
I have been searching all over and perhaps I'm not understanding what is being said so if it sounds familiar and there is a solution then i'm thankful.
So about a week ago, the phone came back from repairs and had the motherboard replaced after the phone was washed by accident. Nonetheless, there hasn't been any hardware defects besides signal loss now and then.
When the phone came back, it had 4.2.2 and it automatically picked up the update to 4.4.2 which I did. The phone worked fine until 2 days ago, where it just stuck at the Samsung galaxy gt-i9190 screen and just freezes there.
I can boot into a custom recovery (Philz) (not stock recovery for some reason) and download mode. I then attempted to install CM 11.0 as I got frustrated. It worked, booted past animated logo and install the apps until i came to the language section where the touchscreen which didn't work (unresponsive). I then reverted back to the stock ROM found at sammobile (i9190xxxCOD2XFA - South Africa), loaded the custom recovery and still no booting past the first screen. The custom recovery touchscreen (Philz) is also non responsive (besides using the volume keys, home button and power for navigation).
I flashed a couple of times, nothing works.
Is there a root cause to these issues? The unresponsive screen, not booting properly?
Some info: KNOX is voided 0x1
Please help!! Thank you in advance
It's not „root“ that cause your problem. You should have to choose right recovery for your model. Flash back to original ROM and look for one of fully supported custom ROM here on the XDA and fallow all steps how to flash it properly. Succes ! Cheers !
Alright, I'll try that. What I did in the meantime was flash, Slimkat 4.4.4 UNOFFICIAL rom for I9190 (http://forum.xda-developers.com/showthread.php?t=2708677).
The rom booted into the andoird system but the touchscreen is still unresponsive.
@Boombastical .. If you can help me by giving me a guide in order to do what you say, then please do help. Even in recovery especially TWRP the touchscreen is unresponsive except for ClockWorkMod and Philz. So i don't know if it is hardware related or I'm doing something wrong.
Its driving me crazy :crying:
Update
So what I did last night:
I loaded the SlimKat rom and based on the stock bootloader and after doing a couple of battery pulls the screen starting functioning properly. However it was just luck or could've been something more technical.
I need help in understanding why that happened.
Then I decided I dont trust my method and reloaded the stock 4.4.2 firmware from sammobile. What then happened, is that it booted past the "Galaxy GT-I9190" screen into the samsung logo and then installed the applications. Come to the choose language screen, the touchscreen became once again unresponsive.
Bear in mind, that when I did a reboot with the stock rom, it didn't want to boot past the screen and just hung there.
So what could my problem be?
Is it the rom that I used? Using Unified Android Tool, I saw my region code is GB which I haven't seen anywhere in the stock roms.
Could the system somehow become corrupted? Emmc, partitions? Could the screen calibration be out of sync?
Must the bootloader always be the stock one? Are there custom bootloaders that one can use?
Please help, thanks

Possible solution:
So I thought it could be screen calibration so this is what I did to make my phone work.
I loaded the CARBON Rom as I somehow lost root privileges with SlimKat. It loaded into the OS as per normal but the touch screen didn't work. So after numerous battery pulls, i read this post http://forum.xda-developers.com/showthread.php?t=2353972&page=1 .
So then I connected the phone to the pc (having had the samsung drivers installed as well as adb) and booted into cmd promt as admin.
This is what I did in cmd prompt:
cd adb
adb shell (make sure there is a "#" as that ensures you that your phone is rooted)
echo 0 > /sys/class/sensors/proximity_sensor/prox_cal (did this several times)
echo 1 > /sys/class/sensors/proximity_sensor/prox_cal (did this several times)
@xcxa23
It then still didn't work (the touch screen) then somewhere on one of the pages in the above post, someone mentioned holding home button. I switched the phone off, I then held the home button (until it booted into the OS) and then powered the phone on. The phone booted into the OS and presto the screen worked again. I did a reboot and the screen is still fine.
Again I'm not sure if its that exact method but what I am sure of, is that I did a clean rom install (an option in Philz touch recovery), wiped the cache, formatted the options (boot, system, cache, preload, data) in mounts and storage and then proceeded to install the rom from the sd card.
I haven't tried with the stock rom as yet so if this helps you, goodluck and if you can help improve on this method or help me understand why this is happening, it would also be appreciated.
Thanks
Confirmed for that is

Hey guys, just a quick update.
I reloaded Cyanogenmod mod CM13. I can confirm that my screen didn't freeze up and booted perfectly. I also then decided to take a chance adn reload the stock rom 4.4.2 and it also worked perfectly and booted directly into the OS.
I'm guessing the screen calibration was out.
So if this happens to you, I would suggest loading a custom rom and doing the screen calibration reset through adb and then test again with another custom rom. Once you comfortable, you can reload a stock rom.
I used Philz Touch for recovery
Thanks to everyone who put posts up .. Time to rest
Not working again!!
Hey,
So in my previous post I said I got it to work. Well I did, up until a few minutes ago when the phone just decided to freeze up again. I restarted the phone and would you know, back to square one!
I've noticed issues that I'm wondering if they could be the problem:
1) The audio didn't work at all. By audio, I mean the mic. When I did voice recording, it just gave static, whatsapp calls, the other person can't hear you as well as regular phone calls.
2) I just rooted the phone in order to change the audio_policy.cnf and delete lines relating to the above audio problem but then the screen, return, and menu button didn't function. The screen could still rotate until I pressed the power button to lock then unlock and then it didn't unlock :crying:
So once again, some help guys please. Is it rom related, hardware (motherboard, chip) or software that just isn't working right? Could it be KNOX?
Thanks
Hi everyone
I'm running out of ideas, maybe someone here will be able to give me a hand.
I have a D855 on stock rom (marshmallow), no root (it used to be rooted on LP, but I guess the update to MM 6 months ago disabled it, right?)
Right after turning the wifi on, my phone rebooted by itself, started ok and I was able to use it normally.
The next day, same thing happened, but this time it couldn't reach the lock screen : I'm stuck in bootloop, right back to the LG Logo after it "optimizes app 52 to 52" and "Android is starting".
The phone is still on warranty, but I'd like to backup my contacts (and maybe texts) before droping the phone there.
(I tought sync with my google account was on, but apparently it's not the case, and I lost the 2 last years of contacts...)
I can access the reset factory mode (not an option for the moment since I'd like to backup)
I can access the download mode : I did a Normal Flash with a MM stock rom through LG Flash Tool 2014, flash succeeded but same bootloop problem at the end.
I can access the phone while in download mode via "LG Mobile Support Tool". I tried the "recovery after error" option, it downloaded the last KDZ (I guess) + flashed the phone, but same bootloop problem occurs at the end.
I guess there is a wifi hardware problem which causes the reboot. Is there any possibility to switch off the wifi module before start up? Maybe if wifi module is off, I will be able to turn it on and do a quick backup...
Or, is it still possible to flash a recovery system so I can do a nandroid backup and try to get the infos I need from that? (thought I think I need to be rooted to do so, and don't think I can since the bootloop problem)
Thanks for reading, and hopefully someone will have an idea
I tried with a new batteur today : still bootlopping...
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.
Hi Everyone,
I have a 5T running android 9 - completely stock. The device is SIM free, I have never customised it at all - if anything it's never been connected to a PC even.
A few days ago I was using my phone as normal (on whatsapp) but it completely froze. It now boots up to the "Your device is corrupt and cannot be trusted and may not work properly" - it freezes on start up and won't work at all.
- I can get to the fastboot screen
- I can get to the recovery screen to install from ADB
The fastboot screen says in red - device state - locked.
The device is a clean, un-customised phone. Only a few days prior I checked for any OTA updates but I haven't received android 10 yet.
I haven't flashed phone firmware or anything for years now. (By years, I literally mean years - back in the Nokia 8210 days). My only other experience of flashing firmware was with Samsung phones and 'debranding' them.
As I was not trying to root the device or anything - how do I fix this issue? I've searched the forums but I cannot fine a scenario similar to mine therefore I'm a bit confused as to what to do to resolve it.
I've tried to sideload this - oneplus.com/uk/support/softwareupgrade/details?code=PM1574156155944 via recovery but it says installation failed.
Any help appreciated thanks!
Sounds like you're straight out of luck to recover any data if your device is completely stock, as to unlock your bootloader to access encrypted data would mean a factory reset. You could try try one of the unbrick tools using the guide here. You will lose your data.
I tried the unbrick tool here - forum.xda-developers.com/oneplus-5t/how-to/oneplus-5t-unbricking-tool-confirmation-t3733012
... and it doesn't work. The phone now boots to a blank screen with a constant white LED.
Could this be a hardware issue?
I'm not too concerned about losing my data - already gave up on trying to keep my data when the problem first occurred!
After the 4th use of the unbrick tool (each time it completes successfully) I was finally able to boot into the phone.
I got as far as setting the region but then it wouldn't find any wifi networks. It then completely froze on this screen and is now back to "your device is corrupt and cannot be trusted" and will continually try to boot and freeze on the oneplus logo. Sometimes it will boot to a blank screen with a white LED.
Has anyone else had this issue? I'm definitely suspecting a hardware issue now...

Problem fixed?
unfortunately not. Any ideas on next steps?
That's an odd issue for sure. My only idea would be installing TWRP and maybe formatting from there and using fix permissions etc. to see if it has any effect.
I've done some googling to try and understand "TWRP" but I'm not sure I fully understand. Are there any forum posts I can refer to?
- phone has been flashed several times
- before this whole saga dev mode was enabled, but only to reduce animation scale - USB debugging was never enabled
- the phone has always been stock / sim free - never rooted
Thanks
Can you get into recovery? If yes then try connecting to a pc whilst in recovery as it should let you open your phones internal storage on PC but im not too sure if stock recovery allows it, (TWRP) does. Then copy whatever files you need. Let us know if you can get into fastboot mode aswell
It sounds similar to an issue I have just experienced with a friends 5T. In my case it's a hardware issue (seems like Wi-Fi has died). Just for kicks try to flash the Android 7 firmware. For some reason it allowed me to boot the phone fine and use it, albeit without any Wi-Fi. I sideloaded OOS 4.7.6 and that seems to be the last version 7. You could also use the older unbrick software. Academic I fear as I think you have a hardware issue.
