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

Rooted, Custom Rom a huge fail

Hello dear Community!
It is depressing that my first appearance here is to ask for help, but I am going crazy.
So, I tried to Root my phone via Odin + CF Autoroot klte and it seemed to have been a success.
The root checker also said, that my device was rooted so I went on and installed TWRP to be able to install Lineage OS.
After getting Lineage to work I got a few error messages suddenly popping up, telling me that either "Music had stopped" or other android operation were closed because they didn't work properly.
I tried to install Gapps, it seemed to have worked but I was only able to open and enter the store once, afterwards the store never managed to load and then the app closed itself after starting it.
So I checked again with Root Checker, but this time it gave me an error message, too. It said, that my device was not rooted properly.
I guess this is were I made it worse by deciding to just root the phone again. Obviously, it didn't work either.
Afterwards I thought that maybe installing The Original Android OS and then unrooting the phone would be the best solution to be able to start anew.
First I tried to flah Lineage again and that made it impossible for me to boot the phone. The farthest I got was the setup page, were it tells you Hello and were you can choose a Language, but clicking the arrow key didn't do anything at all.
The recovery mode was also not the TWRP one anymore, but the original Android one and that was a huge problem for me.
Then I tried to flash the 6.1 OS for the S5 (I made sure it was the correct version), but now it is stuck at the "Samsung" screen while it boots.
It never boots though.
I don't know what to do anymore.
Please, I beg you, could anyone help me out?

Don't flash the latest Lineage OS ROM
Hello AsylumAlice u shouldn't have flashed the latest Lineage OS ROM because now u will need a new motherboard for your S5 since the ROM corrupts the MMC chip now u will need to get a new MMC chip or a new Motherboard sorry that your s5 is now hard bricked but when u get it fixed flash the DreamUX S8 Rom it works flawless on my S5 SM-G900i

What are the grounds for your claims?
You needn't root via CF-autoroot if your end goal was to flash lineage. CF autoroot was intended to root stock roms with ease and less effort.
Flash The LATEST, official TWRP via odin then do a FULL WIPE. Wipe system, data, cache and dalvik cache.
From here on, you have two options:
1.) Sideload the LineageOS rom via ADB
2.) Transfer it to the phone's storage via MTP and flash it from TWRP.
As for how to accomplish this, the forum search bar and Google has your back. You need only choose one procedure.
If you need the Play Store, flash gapps AFTER flashing LINEAGE AND BEFORE REBOOTING.
Since you were under the idea that utilizing CF-autoroot was a necessity, I suggest that you re-read this post thoroughly before actually putting it into practice.

Thank you so much for your fast reply!
-> I flashed the newest Version for klte via Odin, but I can't get into the boot mode.
I only am able to enter the download mode. What can I do now?

Flash TWRP via odin again, untick the Auto-Reset option of Odin first. Then try booting to recovery via long holding the power, home and volume up button simultaneously without releasing any of the buttons until you successfully see the TWRP splash screen.
If that still doesn't work, reboot to recovery via adb from download mode. You need the adb and the usb drivers for your device.
If that still doesn't work, you might have flashed an incompatible version of TWRP.

Thank you so much, it worked perfectly!
I can now start my phone and use it normally.
But the Root Checker still says:
"Sorry! Root access is not properly installed on this device.
Device: SM-G900M
Android version: 7.1.2"
What should I do from now on?
Thank you so much for your help (agaiN).
And as for why I used the auto-root, well I just followed a guide that I found, it only had positive reviews so I assumed it was a correct tutorial.

I thought about doing that, but wasn't sure how exactly to proceed and what Version to install.
I downloaded SuperSU v.2.82 and put it on my internal storage.
Just install over TWRP the same way that I Installed Lineage and Gapps I suppose?
I guess if it doesn't work out, I just follow the steps from above again and retry?
Thank you so much. I feel like in idiot in this situation.

[Bootloop] N9005 not booting after frame (display) replacement

Hi,
as the title says, my phone is not booting anymore, after I transplanted the motherboard from a frame with a broken screen into a new frame (from china).
Abbreviations used:
RR => Resurrection Remix 5.8.5
CWM => ClockWorkMod Recovery 6.0.4.6-kitkat
TWRP => TeamWinRecoveryProject 3.2.1-1
I was using RR from the Rock Stable Setup on it before and it worked beautifully.
What happened:
I performed the mainboard-transplantation according to the iFixit guide
I held the power button to boot the phone:
It vibrated
It showed this screen for a couple of seconds
It vibrated
Back to step 1
And that until I removed power.
Then I tried to boot into recovery mode by holding the key combination on boot:
Same as above, but with this bootscreen
Then I tried to boot into download mode by holding the key combination on boot:
The warning to confirm download mode poped up and I got to see this screen.
I connected it to my PC and opened odin 3.09 and it recognized the device.
I tried to get adb and fastboot to see the device, but nothing worked. (In the old frame and before I broke the screen, it would be recognized at this stage)
I flashed TWRP with odin, odin showed the green "PASS!", but booting to recovery still failed.
I proceeded to flash a stock ROM, which had worked when I had issues with RR.
It worked, I went through the Android 5 setup process, enabled debug and connected adb.
adb saw the phone.
I rebooted to recovery and stock recovery booted correctly.
Sideloading anything with adb failed due to signature verification.
I then went back to download mode and flashed CWM successfully.
It now boots into recovery, but whenever I try to flash anything with CWM, it fails showing this screen
Or something similar (the photo comes from flashing RR 5.8.5)
I have both linux and windows properly setup and used both with adb, fastboot and odin (only windows)/heimdal (only linux).
I checked drivers and usb cables.
I opened the phone back up and checked all connections.
But I can't get any version of RR, CyanogenMod or LineageOS on there.
I've searched the internet, but people that have these kinds of problems after replacing parts of their phones, seem to only have driver issues or skipped steps in the manuals of custom ROM installations.
If you have any idea on what I could try or what I'm doing wrong or not doing, please leave an answer.
I'll keep this post updated below here:
(no updates, yet)
Thanks so much in advance
Simon

Your picture shows stock recovery not CWM .
Try flashing TWRP recovery through Odin .

I did flash TWRP and afterwards there was no recovery anymore.
When I flash CWM, I get the recovery shown in the photo.
The stock recovery has a black background and no touch controls for me.
What you saw must have been CWM.

Update: I can flash twrp-2.8.7.0-hlte-4.4.img.tar and it works. It's the only image that works, but I still can't boot into or flash any custom OS.
The only working OS I have at the moment is a stock android 5.0, which is not all that useful...
If anyone has an idea, why I can't or how I can find out what is causing it, please say so.

What do you mean by ANY ??

Well, exactly that.
Regardless of what zip I flash, I end up with a bootloop.
If I flash a recovery zip, the recovery bootloops, but the OS still boots.
If I flash a custom ROM, I can still boot into recovery fine, but booting normally results in a bootloop.
The only way to get software onto my phone has been via odin and only an old CWM, Philz Touch, TWRP (Version 2.8.7.0 and below) and STOCK Android (Versions 4.3, 4.4.2, 5).
Anything else I have tried so far did not result in an error, but I couldn't boot into it either.
If you have ideas for software I can try flashing, please tell. I really have no idea how to get the damn thing to work again...

What happens when you flash correct stock rom via Odin ??

I mean that I can boot into it after flashing it via Odin.
But its terribly slow and bloated compared to ROMs like ResurectionRemix, so I don't want to use it.

In that case phone is OK .
Usual is that user is failing to follow instructions .
Not sure what you mean by fastboot on a N9005 .sounds like not a N9005 .
Personally with TWRP 2.8.70 i would be flashing something like .
https://forum.xda-developers.com/galaxy-note-3/development/rom-magma-nx-rom-t3508672
as its correct TWRP .

I am able to follow instructions.
Thank you very much.
I followed exactly the same procedure that has worked many times when switching between custom ROMs.
Also, the phone has a perfectly working version of Ressurection Remix installed at the time my frame broke and it did get stuck in the same bootloop after replacing the frame, even thogh the software was exactly the same.
I am looking for help analyzing the boot process and some way of capturing the kernel log when booting to determine where the error occures that traps the phone in a bootloop.

Dear Mate..
Have you solved your problem? I have same problem after transplating N900 frame.

Sorry, I gave up, since I dearly needed a working phone and bought a OnePlus 3 cheaply from ebay second hand. It's been working like a charm and I threw the note into my museum after I softbricked it for the n-th time and couldn't get it out of a bootloop that didn't leave me time to go into Fastboot.
Sorry friend, but I can't help with this.

after reading a lot of similar threads, seems like the hardware is the cause of us not able to update to higher versions of twrp(& custom roms)

I hope you did not pause the download in between or it did not failed and you started from the failed point (It can be done in Firefox)
Check the md5 of the zip file.
Also try a different TWRP. What TWRP are you using right now??.......just tell what source you downloaded it from

TWRP, Rooting and Custom Rom HELP SM-T510 Tablet Tab A 10.1

Hey guys, this is my first post. I just bought a Samsung SM-T510 and would like to unlock all the features. I'm currently trying to follow multiple guides on how to do so. To my understanding, my best bet is lineageOs 16. I've been following https://forum.xda-developers.com/gal...-16-0-t3987317 alongside with https://forum.xda-developers.com/gal...howto-t3989361 and I'm pretty confused on the method order i need to follow. What I mean is do I install rom first, TWRP, Magisk etc.?
More guides ive been following:
https://forum.xda-developers.com/gal...-10-1-t3934805
https://forum.xda-developers.com/app...mless-t3473445
https://topjohnwu.github.io/Magisk/i...system-as-root
I see posts saying I need and don't need Multidisabler so I'm confused on what I actually need: https://forum.xda-developers.com/gal...ption-t3963020
Another one: https://forum.xda-developers.com/gal...ption-t3919714
https://forum.xda-developers.com/gal...eries-t3918699
I have so many tabs open currently; I know I'm missing a few important ones.
So given all that info, i think i have all the software to do this between kernels, rom, twrp, odin, magisk, multi disabler? and i think thats all.
My sm-t510 build number is T510XXU2ASK5, looking through the lineage rom guide, I click the link https://samfrew.com/model/SM-T510/ and i see different versions. I'm honestly completely confused about this file and how I'm going to use it. I understand it to be the stock rom? as in factory software? With TWRP too, the numbers don't match my current build number leaving me very confused.
Do I need to downgrade my build number (i don't know if it's even a thing just asking)?
I think i can do everything relatively easy once I have an understanding of what to do first (order of things) and the specific files for the specific steps. When I'm reading these guides, I honestly have no idea which download goes for what. For ex. going back to https://forum.xda-developers.com/gal...-16-0-t3987317 like what do I need to download, the build number listed in notes regarding kernel or go to the download section right below and use that? Or both and if both, how do I use them separately for there a specific purpose? I cannot find anything that makes me feel comfortable rooting/custom rom on my device. Not comfortable in terms of I don't know what I'm doing exactly. I have put days of reading into this and still, I cannot figure out how to do this. I would really appreciate it if someone could help me. This is stressing me out and I would like to get this done before Monday due to me having some serious surgery. The reason being; I won't be as fresh on everything I've read recently.
I'm sorry if this post is choppy and all over the place. I'm just exhausted and clueless at this point. If I left any info out in order for someone to help me please let me know so I can provide it.
EDIT: The TWRP file ends in build number SK1, the file lineage-16.0-20191019-UNOFFICIAL-T510XXU2ASI4.tar.md5 doesn't match the TWRP file as well as my current build number; which ends in SK5. So nothing is matching the 3 last characters in my build number across all guides besides the samfrew link.
Also, I keep seeing i need a .tar TWRP file for recovery (?) but when I unzip both files are .img (named boot/recovery)

You don’t unzip the .tar files. Keep them as is.

I don't get a .tar file until I unzip the folder; I get a filed with .tar.md5

My recommendation would be to first upgrade to T510XXS2ASK1 of the OEM firmware, since that's the latest version for which Samsung has published kernel source. Use the latest release of Odin and install BL, AP and HOME_CSC. After this, unlock the bootloader and prevent VaultKeeper from relocking it by always enabling Debugger Options while connected to the Internet after a factory wipe.
From there, you could just install TWRP, install the latest MultiDisabler, and live with the Samsung firmware. You could even install Magisk to root. However, I prefer a clean Google OS without all the OEM bloatware, so I'd recommend installing the latest Nexus Stock (which includes TWRP and the custom kernel that disables Knox boot security features). Again, use Odin and install it to AP and do a factory wipe in TWRP because file-based encryption is still unsupported on these custom ROMs.
You could install LineageOS instead, but I haven't yet updated that for T510XXS2ASK1. I've just been busy and Andy hasn't been releasing any new LineageOS 16 GSIs. We're also pretty close to releasing a LineageOS 17 build.

Just rename the file cutting off the .md5.

is it possible to downgrade from sk5 to sk1? you cannot upgrade to a later version, and I know downgrading can have reverse effects on the tablet. I have same tablet I would like to know. if I flash sk1 is there a way to fix it if it bricks?

Hey guys, this is my first post. I just bought a Samsung SM-T510 and would like to unlock all the features. I'm currently trying to follow multiple guides on how to do so. To my understanding, my best bet is lineageOs 16. I've been following https://forum.xda-developers.com/gal...-16-0-t3987317 alongside with https://forum.xda-developers.com/gal...howto-t3989361 and I'm pretty confused on the method order i need to follow. What I mean is do I install rom first, TWRP, Magisk etc.?
More guides ive been following:
https://forum.xda-developers.com/gal...-10-1-t3934805
https://forum.xda-developers.com/app...mless-t3473445
https://topjohnwu.github.io/Magisk/i...system-as-root
I see posts saying I need and don't need Multidisabler so I'm confused on what I actually need: https://forum.xda-developers.com/gal...ption-t3963020
Another one: https://forum.xda-developers.com/gal...ption-t3919714
https://forum.xda-developers.com/gal...eries-t3918699
I have so many tabs open currently; I know I'm missing a few important ones.
So given all that info, i think i have all the software to do this between kernels, rom, twrp, odin, magisk, multi disabler? and i think thats all.
My sm-t510 build number is T510XXU2ASK5, looking through the lineage rom guide, I click the link https://samfrew.com/model/SM-T510/ and i see different versions. I'm honestly completely confused about this file and how I'm going to use it. I understand it to be the stock rom? as in factory software? With TWRP too, the numbers don't match my current build number leaving me very confused.
Do I need to downgrade my build number (i don't know if it's even a thing just asking)?
I think i can do everything relatively easy once I have an understanding of what to do first (order of things) and the specific files for the specific steps. When I'm reading these guides, I honestly have no idea which download goes for what. For ex. going back to https://forum.xda-developers.com/gal...-16-0-t3987317 like what do I need to download, the build number listed in notes regarding kernel or go to the download section right below and use that? Or both and if both, how do I use them separately for there a specific purpose? I cannot find anything that makes me feel comfortable rooting/custom rom on my device. Not comfortable in terms of I don't know what I'm doing exactly. I have put days of reading into this and still, I cannot figure out how to do this. I would really appreciate it if someone could help me. This is stressing me out and I would like to get this done before Monday due to me having some serious surgery. The reason being; I won't be as fresh on everything I've read recently.

without reading answers i can say that im with YOU! Im almost 3 days to root my T510! We must RAMDISK YES in Magisk but to do that we need to extract recovery.img (https://www.droidwin.com/install-magisk-in-recovery-root-android/) from stock original ROM T510OXM5CUJ1 and Im stucked at the part NORAMDISK trying to patch recovery.img with Magisk Manager (with recovery mode checked) but i only get the "waiting for device in ADB" and I conect disconect USB C and nothing...Still NO RAMDISK...
I used 3 different ROMS but no lucky and tried with firmware CUJ1 but no lucky again. Without "NORAMDISK: YES" no root...stucked. But i saw a T510 with OrangeFOX!

I just finished flashing the latest Nexus ROM and rooted it with Magisk merely by flashing the Magisk zip file. You can flash the Nexus ROM without first flashing anything else but the latest CUL1 (not CUJ1) stock ROM. Nexus includes both TWRP and gapps. The only time you have to patch things to get Magisk installed is when you are trying to root a stock ROM instead of a custom ROM. Custom ROMs always to the patching for you.

You don't need to flash TWRP if you flash https://forum.xda-developers.com/t/...k-for-2019-galaxy-tab-a-10-1-sm-t510.4234889/ TWRP is built into this ROM. After installing stock CUL1, did you boot it, connect to wifi, skip the rest of setup and then enable Dev mode before rebooting to download and flashing from Odin?
edit: Don't attempt to download from the regular download link. Use the link under Build archives that says Android File Host and scroll down till you find the CUL1 md5 file.

You must connect wifi and enable Dev mode before flashing. If, after flashing CUL1, you went through the regular setup routine and put in a Google Account, you must also enable OEM in Dev options.

USB cables are notorious for being flaky. Sometimes it helps to just turn the cable over and plug it back in. I always keep several on hand so that if I have connection problems I can try another cable.
