Lg g2 no os at all

Hi!
First I tell you how I recently messed up my LG G2 D802.
I hadn't had a custom rom for ages and now I wanted to have one (This wasn't the first time. I've done this a lot earlier). I had always had root access, but not custom recovery. So the first thing was to install one and I chose to download Rom Manager from Google Play, and then install ClockWorkMod. So, when I was installing the custom recovery I came up with a problem: something went wrong during the installation (I have no idea why). When I booted the device, white letters and numbers appeared on the top left of the screen, saying something like: "boot certification error" and numbers like "[780] [800]" and so on. The screen went black and the phone didn't load the OS. So I was shocked of course because I had never had such a problem.
So, desperate for trying everything to find the solution, I tried tens of ways to try to fix the problem. Finally I read about thing called SRKTool. So I used it and ended up having TWRP on my device, and no OS at all. I tried to flash CM12 and CM12.1 (downloaded from the official site) but nothing works out. TWRP says that flashing the ROM is succesful but when rebooting the system it doesn't load the OS but it comes back to TWRP Recovery mode - WHATEVER I DO. I can't enter the Download -mode at all. I tried hard reseting (Power + Vol - keys), but once again it boots to the TWRP. I can't understand why the TWRP fails to flash the ROM even though it's saying the process was successful. Or maybe this problem is much more internal - and permanent.
After tens of XDA developers' threads I'm writing this here because I'm in need of help. I want to bring my G2 to back in life. I'm out of ideas. Can you help me? I tried to flash the stock firmware but guess what happened? The installation failed, and the device booted back to TWRP. So all I'm able to do is to use the TWRP Recovery. I appreciate your help. Thank you.
(Ps. I'm sorry if I break the rules by writing a new thread. My problem just seems to be so unique that I couldn't find help anywhere.)

If you have access to twrp than you can do what ever is needed
what twrp version douy you have?
enabel MTP, so you can copy from PC

The solution is easy. Download the stock rom for your model and install it with otg cable. The reason cm12 is not booted is because you need jb bootloader or caf bootstacks.

The current version is 2.8.7.3. Should I try other versions?

Did you solve the issue? Or is it still not allowing you to get into your F/W?

Hi!
I tried to install TWRP version 2.6.6.3, but it fails to flash it so I'm stuck with the version 2.8.7.3. All I'm able to enter is just the recovery mode. I can't enter the download mode so I can't flash the stock firmware.
Currently I'm out of ideas. I can't flash any OS, the TWRP fails everytime and creates errors.

Try flash bumped kernel like lp dorimanx then flash bumped bootstak then lp rom like cloudy or stock. Or google this: lg g2 unbrickable now xda ...that work for me

[RECOVERY] [TWRP 3.0.0-0] for Vodafone Smart Prime 6

Hello guys.
I have successfully ported TWRP 3.0.0-0 for our Smart Prime 6.
It's 100% working !!
There are NO BUGS !! :good:
DOWNLOAD
NEW LINK: DOWNLOAD
________________________________________
How to install​​
Via app:
1) Download TWRP 3.0.0-0 from the link above and place it on internal storage of your phone.
2) Download Flashify app from Google Play Store.
3) Open Flashify app.
4) Grant root permissions.
5) Click "Recovery image" and then click "Choose a file"
6) Navigate to the folder where you placed TWRP 3.0.0-0 and choose the .IMG file.
7) Press "Yup!" button and wait.
8) After a while the phone will require reboot. So click "reboot" button.
9) Phone will reboot and automatically boot into TWRP, so you can press reboot to system.
10) Enjoy!
Special thanks to Oneb1t for modded .fstab file! :highfive:
edit: you can use Flashfire app too instead of Flashify, but it's not recommended, because the latest version of the Flashfire app is not flashing properly.

Brilliant! Thank you so much! Do you know any custom ROM what is better than the factory ROM?

There is no custom ROM for this phone yet.
But I'm trying to make LITE ROM.

Do you think it's easier/possible to adapt a ROM from a similar device like say, the Alcatel
Pop 2 (5) Premium ? I don't know if there's any ROM for that phone tho, but since it's branded as Alcatel you might get more support from the community here than by using Vodafone's name.

Hello, Demonlord6.
I have tried to make a stock flashable ROM via dumping the system folder and the boot.img file, but without success.
It does not boot properly.. when I tried to flash it without dalvik/system wipe everything was as before.
When I tried to wipe /system and dalvik first and then flash the ROM, it causes bootloop.
So now I'm trying to fix this issue..
I don't know where the problem is.
So when this issue will be solved I will try to build a ROM from Alcatel phones with same specs.

Hey, Andreno306
I don't know much about Rom's in that level of expertise I'm afraid :/ but I did some digging and came across this simple tutorial on XDA:
http://forum.xda-developers.com/showthread.php?t=2387941
I imagine it does not work for every single device out there, at least not with modifying stuff after, but it might be a good starting point I think, in fact I would try to actually make one myself had I a working PC currently at home. But even if I did I had no way of testing it because this is currently my daily driver phone.

Just wanted to say that I'm also very interested in getting a slim ROM for this device. I can't offer any expertise I'm afraid! Just wanted to show that there are people interested in your project.

I have one
https://mega.nz/#!tMJD3B4T!f6m2ELYCVupqGCcN2aGbkrNzEqijLu7au-7usEfeVL0
But I recommend to restore it with the flashify app, because that's how the backup was made.
If, for some reason, you don't/can't restore it, then you can always try Sugar on the PC which basically restores everything to factory settings (recovery, kernel, etc, it all gets reset)

Sorry there about the bootloop but glad u could restore it from TWRP, maybe it was because we have different ROM versions ?

Sorry for the stupid question but... does it works on Smart Prime 7 too?

Has anyone installed that linked ROM? It seems to be what we are looking for... a slim debloated rom.
I presume we need to be rooted, install this TWRP, then flash that ROM?
It mentions unlocking the bootloader, I dont think I've seen any info anywhere about unlocking the bootloader.
Can anyone give a quick lowdown on all the steps required to install that ROM please?

Hi everyone, I discovered that Elephone Trunk and Smart Prime 6 have (almost) identical specs: https://www.devicespecifications.com...ison/c584481c6
So it would be great to "port" (or build ?) the official Nougat-OmniROM for Trunk to VF-895N: http://dl.omnirom.org/trunk/
Last but not least, here's official Vodafone Smart Prime 6 sources: Vodafone_Smart_prime_6_20150413.tar.xz

TWRP for vodafone smart max 4 990N (coolpad 8890u).
I tried this recovery image for vodafone smart max 4 990N (coolpad 8890u).
The phone is in a bootloop state. I think i have usb debugging enabled already.
So, in fastboot mode i can see the device in my pc in adb fastboot cmd.
Im trying to ''fastboot boot recovery.img" but it stops in ''booting..''.
Dont know whats the problem but for sure i can not find a specific twrp image for this device.
If i enter fastboot oem device-info it says ''(bootloader) Device unlocked: true''.
Any ideas ?

hi i was wondering if you could share how you did this or if you can make one for the Vodafone smart n9 (VFD720) it would help a lot of people out looking for this

Needed to root a Vodafone Smart Prime 6 (VF 895N) (got it from a friend because it became unresponsive from all the updated google play stuff ) to get linux-deploy running. Just wanted to leave a big thank you here for Adreno306 for his TRWP 3.0.0-0. it did the job very well!
Only the procedure to get it installed differed quite a bit for me, since Flashify is no longer available.
I wanted to preserve boot and just flash trwp to recover, what worked quite well.
The first thing I did was to boot the phone manually in recovery mode (Power+Vol up) and reset it to factory settings from there. It takes a little while. Then follow the setup, go to phone settings, enable developer mode and set usb debugging. If "unlock oem" is not available there, reboot into recovery again, set unlock there and reboot into bootloader.
The prerequisites are adb and fastboot, both must work. Means adb devices and fastboot devices must show the phone. What can make problems under win10 as it sometimes does not detect the phone in bootloader mode. An actual google usb driver is needed, as provided by google.
For me adb worked well, but when rebooted into bootloader with adb reboot bootloader, fastboot didnt detect the phone. With the phone still connected, the windows device manager showed an unknown device with and exclamation mark (!). Right click, install driver, select driver manually, select driver from device list, mark all devices (first entry) and click "disk", then point to the usb driver director and select "ADB fastboot driver". ( A more comprehensive description is available here )
Once adb and fastboot detect the device, it is time to prepare it. Boot to system (normal operation) first. Make sure that the TRWP 3.0.0-0.img is renamed to trwp.img and then
adb reboot bootloader
fastboot devices
fastboot oem unlock
fastboot boot trwp.img
Now the phone should show the trwp menu, set it up to root the phone and install SuperSU. Reboot into bootloader and
fastboot flash recovery trwp.img
fastboot reboot
Verify with adb reboot recovery, you should see trwp now. Reboot to system.
Now finally go into the app selector, start SuperSU, and root the phone. SuperSu uses trwp recovery mode to install its image and root is done.
Again, big thanks for providing the TRWP image!

GPS Problems & recovery image

Hello , i have a Lenovo A6000 and after some GPS issue i decided to flash it with TWRP 2.8.6.1 and add a custom (CM11) rom.
After a little bit of picking around and trying various gps fixes i think the problem is hardware wise.
I unrooted the phone (i used kingroot to root, comes with an unroot button) but now i need the factory recovery image so i can return it back for repair (factory rom was backed up from twrp and recovered successfully).
The current (and up to date according to its settings) rom is S025_151016 and its a single sim model. Do i need the same recovery ? I have found the S010_151016 recovery on the internet, is it ok to flash this one ?
Also general tips to fix gps if possible ? I tried TopNTP & various cm11 roms
Thanks for the answers

You can download your recovery as per your current android version from here, and then flash it
www[dot]techolite[dot]com/34431/lenovo-a6000plus-pure-stock-rom-recovery[dot]html
Replace [dot] with " . " in the link
And first try this to check if the recovery wont cause any problem - "fastboot boot recovery.img" where recovery is the name of your recovery image. If the phone successfully boots into it that means you can flash that recovery without any problem.
For permanently flashing recovery - "fastboot flash recovery recovery.img"
Hope it helps!!

Root Failure on my C9 Pro in Android 8.0.0 Oreo

Hi guys. This is my first post on XDA.
Now I've got C9 Pro, and hours ago I just got it flashed with the latest Android 8.0.0 ROM, version: C9000ZHU1CRG9.
Also I managed to flash TWRP. Then I started doing the Root things with TWRP, as I had done on Android 7.1.1.
However, I did get issue while doing the Root on Android 8.0 --
Actually the SuperSU was flashed successfully, but after this, the phone kept restarting, failing to enter the OS.
I am definitely sure I did the Root with the right steps.
Also I tried different versions of SuperSU, still the issue existed.
Then I flashed Magisk instead, no use.
I even used other versions of TWRP, still no use!
......
Finally, I quitted, flashing the former Android 7.1.1 ROM.
I can't use a phone without Root, but I really want to experience Android 8.0.0.
Can someone offer me any solution?
Thanks a lot in advance!

try the latest 3.2.3 and tell if it worked

I suggest to flash a clean oreo via odin then flash the latest twrp from @travis82 then do format data and wipe cache and data from twrp recovery
then install the latest magisk
hope u the best @jasonc417
keep updated

You know what, I already tried TWRP 3.2.3, but failed!:crying:

I have tried almost every combination ended up getting bootloop always except when I tried these;
1. Install stock firmware and csc (not home csc this will fully wipe the phone)
2. After finishing it enters to recovery and updates the system. Keep hold of pressing the volume down+home key to enter to download mode as soon as it finishes installing system update.
3. install twrp from here https://www.androidfilehost.com/?fid=1322778262903985796 (original thread https://forum.xda-developers.com/c9-pro/development/twrp-c9ltechn-t3646970 sometimes links can be dead. In that case you can find new link from that thread).
4. Keep holding of pressing Volume Up+Home key while installing twrp to boot into recovery as soon as the phone reboots.
5. While in recovery flash this SuperSU https://forum.xda-developers.com/attachment.php?attachmentid=4164510&d=1496008012 (Located in this thread https://forum.xda-developers.com/attachment.php?attachmentid=4164510&d=1496008012 as "*** Xperia users, and others experiencing bootloops ***

Your phone should boot normally to setup screen.
After You finish setup you should see supersu icon and your phone should be rooted.
I haven't tested but if your phone is in working condition right now you can try from step 3 to not lose your data.
Good Luck -

Thanks for your method. I think I made it finally!

There is, however, one problem with the given TWRP:
Before flashing SuperSU, I did format, or exactly, mount /data.
But when the phone was rebooted again, /data resumed unmounted, resulting in failure in flashing other ZIPs (It said "unable to mount /system").
Then I got the phone rebooted, the terrible bootloop occurred again!
That is to say, we have to flash all ZIPs in one time after mounting /data without rebooting the phone, but sometimes this is not possible.
Now my phone has gone back again to Android 7.1.1, and I think I have to wait for an official TWRP that supports Android 8.0 thoroughly on C9 Pro!

3. install twrp from here https://www.androidfilehost.com/?fid=1322778262903985796 (original thread https://forum.xda-developers.com/c9-pro/development/twrp-c9ltechn-t3646970 sometimes links can be dead. In that case you can find new link from that thread).
4. Keep holding of pressing Volume Up+Home key while installing twrp to boot into recovery as soon as the phone reboots.
5. While in recovery flash this SuperSU https://forum.xda-developers.com/attachment.php?attachmentid=4164510&d=1496008012 (Located in this thread https://forum.xda-developers.com/attachment.php?attachmentid=4164510&d=1496008012 as "*** Xperia users, and others experiencing bootloops ***
Please use this version instead: "
Your phone should boot normally to setup screen.
After You finish setup you should see supersu icon and your phone should be rooted.
I haven't tested but if your phone is in working condition right now you can try from step 3 to not lose your data.
Good Luck -

I tried your guide & used Magisk v17.2 instead of SuperSU at step 5 & successfully resolved the bootloop problem, but I did encounter the problem of data not mounting even after flashing ashyx_dm-verity zip:

There is, however, one problem with the given TWRP:
Before flashing SuperSU, I did format, or exactly, mount /data.
But when the phone was rebooted again, /data resumed unmounted, resulting in failure in flashing other ZIPs (It said "unable to mount /system").
Then I got the phone rebooted, the terrible bootloop occurred again!
That is to say, we have to flash all ZIPs in one time after mounting /data without rebooting the phone, but sometimes this is not possible.
Now my phone has gone back again to Android 7.1.1, and I think I have to wait for an official TWRP that supports Android 8.0 thoroughly on C9 Pro!

2 days ago I flashed again the Android 8.0 ROM into my C9 Pro with Root successfully, through which I found the actual problem:
The given TWRP only supports the specific SuperSU zip, and while I flash other zip files, the bootloop occurs again. That's why I surrender flashing Xposed zip.

Well done
I can confirm that I have enabled mounting data partition in TWRP after using your mentioned Disable_Dm-Verity_ForceEncrypt_09.02.2018 zip file, Although I haven't followed your steps exactly
I have mentioned my steps in earlier reply.
Thanks

Thanks first.
Well, I do have a question: can I flash other zip files, like Xposed, with your given TWRP without phone bootloop?
Thanks!

New thread with root guide on oreo (8.0) step by step with required files would be appreciable.

Last night I tried this again following the steps, and finally the flash of Xposed and other 3rd-party zip were successfully!
Only one problem: an app named "Toggle Data" could not be run properly.
Again, thanks a lot!

How to do, C9 Pro with Root successfully?

Thanks for your report.
Links and zips are updated. It should unzip fine now :good:

it's ok, just that I had to run the program first and only after that I joined the mobile in the fastboot. Otherwise, he made a mistake
Thx :good:

This is mi8se forum!! TWRP is specific for each phone (different kernel, processor...) so there's no way you could install this TWRP img on another phone than Sirius

Getting this error: FAILED (remote: Failed to load/authenticate boot image: Load Error)
Seems to install correctly but doesn't boot into it. Holding power on and volume up boots it back into fast boot. Any ideas?

Hi! Is there an updated twrp for miui 11 android 10. First time to install this.

This was a long time ago now and I've since changed device. However, I seem to remember having to switch back to the original Chinese ROM and starting again. It allowed me to install the correct version of TWRP I think. But if you do go back, make sure you don't lock your device again like I did. I think there's a checkbox on the program that you have to use to put the Chinese ROM back on and you need to make sure it's ticked. Sorry if I'm not of much help but it was so long ago now that it's hard for me to remember.

My fault is I didn't flash the magisk. I saw this link somewhere here in xda so I didn't know that magisk should be flashed. What twrp did you install?

These were the notes that I left myself:
After boot, go into Fastboot and flash recovery 3.2.3-1217 twrp
Using this, wipe everything apart from bottom box on advanced wipe. Do twice, reboot once in the middle.
Flash EU rom. Do the wipe it promts after install and boot up.
Then use fastboot to flash recovery TWRP-EU, and flash magisk (canary build) to keep twrp installed.
I'm not sure what version this TWRP-EU is, so I've just uploaded it to Google Drive for you here.
Hope this helps.
