Lg v20 keeps booting to twerp recovery after factory reset. Megarom - LG V20 Questions & Answers

Really not loving this phone and this rom. After learning I can't return to stock. Decided to factory reset it andoesn't then it boots directly to twerp recovery. Do did the first factory recovery from within the phone. Then after it booted into recovery I did a factory reset rhee and reinstalled the Megarom version 4.0. That didn't help as it booted back into recovery. So I restore a previous backup that I made from version 3.4 and that didn't work either. Sad thing is I didn't even root this phone myself. So I'm clueless as what's causing this. Someone help me please. How to I get it to boot properly?

Probably not the fault of either the phone or the ROM.
You should expect resultant problems if you have no idea what you're doing.
You may have some luck asking in the Megarom thread.

Listen rather than being useless and rude why not try to help? Otherwise be quiet. Also I figured it out on my own so thanks for nothing. And also I said I wasn't the one who root the phone and installed the Rom. All I did was factory reset it which was normal and which is something everyone does. So clearly you are being an a** . anyway I figured it out and the phone is fine so thanks to nothing. Goodbye.

As you complained about the ROM I helped by suggesting you ask in the specific ROM thread. I'd have thought you would have done that in the first place.
Glad you managed to sort it.

how dod you fix it?
I'm having the samw problem right now and if you could lmk how you fixed it that would be awesome, thanks in advance bro

When you do ANYTHING that normally would need the stock recovery .. IE: factory reset from the OS, then it writes to the misc partition so the phone will boot into recovery.
Fix:
While in TWRP
adb shell
From the shell:
dd if=/dev/zero of=/dev/block/bootdevice/by-name/misc bs=256 count=1 conv=notrunc
Reboot...

Actually, this is a reoccurring bug part of the TWRP build (or engineering bootloader, i'm not sure) of our device. Not the user's (or ROMs) fault at all!
I had this issue after trying to use the OTA update function of LineageOS. Your best bet is to not run anything that will request rebooting to TWRP in Android.
I fixed this issue by flashing the stock recovery and formatting /cache, then flashing twrp back.

Stuck in cwm recovery!! Help!!!

Okay, so here's my situation...
I installed TWRP with no issues, and a few days later installed CWM recovery (just because it's what I'm used to from previous device usage), but just today an OTA occurred. Yes, I'm an idiot and was warned not to do this and for that I am getting hit my some severe karma. Anyways, all I want to do is get my device working again. I could care less if it's stock, and I lose all of my data. I just want it to return to normal functionality. I'm on CWM version 6.0.4.4 and have no ADB support so I'm unable to push any files for a restore. Also, I have backups in my TWRP folder, but cannot access them from the restore from /sdcard menu. If anyone out there could help me out I'd be so damn grateful. Thanks!!!

Actually, I can't even revert to stock. Don't have any files that I can use to restore. Can't push them from PC. I think I'm out of options. Unless you can think of anything. Is there anyone I can directly get a hold of to help resolve this for me? I know I'm not the only one who has gotten this error.

FIXED!
If anyone out there needs help with this issue, I've found a very simple quick fix.
1. http://koush.com/post/universal-adb-driver Download and install this. For some reason it enables you to use ADB while in CWM.
2. Plug in your device while powered on and in recovery mode.
3. Now, enter the following commands in order.
adb shell
dd if=/dev/block/platform/msm_sdcc.1/by-name/fota of=/sdcard/fota-backup.img
dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/fota
4. TA DA! You should be able to reboot your device in full functionality!
Note: The command prompt was copy and pasted by me from this forum --- http://forum.xda-developers.com/showthread.php?t=2451696
Big thanks to thecubed for getting me outta this one!

I am in the same situation. Please describe it in detail as to where to enter the command. Specifically where do I get "adb shell" and how to get this command prompt. Thank you so much
I was having the same problem tried everything to get it to reboot even the universal drivers still didn't work. I ended up using ubuntu and installing the jdk and sdk then ran the command that was in the TWRP tutorial (http://forum.xda-developers.com/showthread.php?t=2451696) and it worked like a charm. 9 hours though :/ hope this helps a little bit. if you dont have a computer running ubuntu just make a live cd and you can do it from that!
this was the link to the question I had posted.

Continual Boot to TWRP [T-Mo]

So for the first time in my history of Android's since the G1 I've finally bricked a phone. Apparently there was an OTA for the T-Mo devices and I managed to hamfist my notification and accept it.
Needless to say I'm now stuck permanently booting into TWRP. I've tried some various troubleshooting methods including doing what I thought was a successful sideload of the TMo-Stock-Rooted Rom. It showed a successful push and ran through the install but I got a message kicked back saying "No OS installed". Now I've seen other users receive this same message and after rebooting anyway they got their ROM to boot.
No such luck for me, after it reboots (post sideload install) it shows system as unmounted and then just boots back into recovery ad nauseum...I'm really at a loss here folks.
Have you already tried this?...

Hadn't tried it previously but I just attempted to run the ADB command and it still boots into TWRP. I'm not sure if those commands worked or not however. I got a big wall of text in terminal after the second command.
FWIW, on every reboot System is unmounted (Data & Cache remain mounted) but I can check it. Seems that it's irrelevant whether its checked or not.
Tried a sideload using the Stock Rooted 110G image and still nothing. Sideload appears to go, and install goes through without error but reboots only into TWRP with System unmounted.

can you get the phone to shut off and stay off. If you can then simply put it in download mode and use LG flash tool to flash stock rom back on. Please let me know if this is an option if not I will try and figure out something else

I can get it to shut off and stay off no problem. I'm on OSX at the moment and likely won't be able to get to a PC until the 9th. I'll definitely give the LG Flash tool method a try when I can.

Haha I hear you. I moved recently and the apt I'm in doesn't have ethernet drops so I had to order up a PCI wireless nic card =\ I'll dig around for the LG flash tool guides and see what I can learn.
I was hesitant to even flash a recovery because of how ass backwards LG made it for us in the first place =\

brother I feel your pain. But when you get everything all situated I will tell you the easiest way to install a backup recovery program. It is an app in the App Market called free GEE... One click and bam you have a backup lol.. You may want to use freegee to make sure twrp is installed right.. It will just over write all the files and correct any wrongs... Freegee.. Remember that!!

No worries friend! I almost went crazy last night trying to find a fix!! Here what fixed mine!
You need to be EXTREMELY CAUTIOUS when typing this in:
Go to Advanced in TWRP and run Terminal
dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/fota
then hit go
after it pushes through again type:
dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/misc
then hit enter and reboot.

Are those commands pushable through ADB? For whatever reason when I get to the Terminal Command through TWRP it wants me to navigate to a different directory and there's no command line to type things in. I've always been a CWM flash a .zip kinda guy so digging into ADB is all new for me.

Ran the terminal side commands, got to LG Splash and we're sitting there now. We'll see how long it sits or if it's a boot loop.
**EDIT**
10 minutes sitting at the LG splash no go. I managed to snag an interim wifi adapter for my desktop so I'm going to try the Flash tool posted from earlier and see if it works.
Update
I was able to bring the phone back with those commands using adb thank you guys for your help.

Can't say for sure, I had seen some to run this way:

Did you have any driver issues? I'm stuck in the same situation booting just to ClockworkMod Recovery after an attempted OTA update. Can't connect to Win7 because driver can't configure properly even with the latest drivers installed. Connects file with my wife's working LG G2 so I know the drivers are right. Also tried to get into download mode with no luck. I'm stuck. Does anyone know how to get pass this?

OK. Finally got it working. Wish I had figured it out before I factory reset my phone. My main issue was the driver. Even though I had the right LG drivers installed, it just would not recognize it properly. Here is what I had to do after a failed device configuration.
- Go to Computer Management and find the failed device and Update Driver.
- Choose to manually select device and then select Have Disk.
- Find and select \Program Files (x86)\LG Electronics\LG VZW United Driver\64BitADB\lgandadb.inf (Tried the other xxxadb.inf files but none worked)
- When the list of devices is presented, scroll down and select LGE Mobile Server Single ADB Interface
Your device should now be recognized by adb. Follow the steps provided by others above in this thread and you should be good to go. Worked for me. Good luck.
Thank you all for the great knowledge base. Saved me $500!!! ::good:

Nexus 6p showing 'No Sim detected' help

The 6p is showing 'No Sim Detected' for some time now . I've tried doing the following steps but no result yet. Got no other back up phone so would be grateful is someone could point me in the right direction.
My build number is 6.0.1 (MTC20L) , also says 'unknown' under baseband version.
1) Yes i tried taking out the sim and back in several times , no result
2) Tried to restart , reboot still no result.
3) I've tried a full factory reset after backing up on helium of course , from the power and volume down steps .
4) I've tried wipe cache from the the power and volume down steps
5) some sites suggested to look in to the ##4636## and turn off and and switch on the radio. This is where it got really confusing since the option simply did not click , (it didn't switch off or change in any way, it was stuck in switch off the radio!!!!)
6) Tried unlocking the bootloader and flash factory image (this includes the radio image) , no change
Any one got any idea whats going on? maybe some thing to do with the modem ?

Yeah i managed to get past this problem and executed the commands you gave me .
still after i switched off and on my phone there was no changes, the base band still says 'unknown' .
Should i flash the factory images and return to stock ?
Also does returning to stock mean that i return to the very first build , or it the current build image i am on right now (mtc20l) ?
Have you tried the sim card in a different phone just to make sure it's OK? If it's not the card, it might be the sim card reader that's broken. You could also try another sim card in your phone. The message is actually 'No Sim detected', right? I had 'No service' show up one morning, did every wipe I could think of and eventually locked the bl, flashed a clean stock image and took it back after reading it might be the antenna. Basically they changed the internals and I just got it back yesterday after 2 weeks. All good now.
Edit: you can basically flash any stock you want. I actually got mine back with a may or june patch (and a flat battery.. :/ ). Out of curiosity I updated the phone with otas up to nougat. It took 6 or so update cycles. Kind of a frustrating thought if I was the customer who actually would've wanted to start using it straight away

Yeah i tried another sim card before and there was no change .
I don't think it was the sim card reader because my base-band version does not show up at all (plus no imei number ).
Also it did work for a few minutes with the orginal sim card but showed the network name and displayed 'no service' but this time the baseband version and imei number worked, that is before it went back to 'no sim detected' and been stuck there ever since then !
I had the same problem yesterday after flashing new rom, I flashed Radio in recovery then reflashed vendor & rom, everything's working right now.

Sorry i'm very new to this and don't know the terminolgy very well.
so when you say flash radio in recovery, is it the same commands that you use in heisenberg's guide for n6p but instead of bootloader you do it after entering recovery ? :
Code:
adb reboot recovery
fastboot flash radio C:\angler\images\radio-angler-angler-xx.xx.img
fastboot reboot-bootloader
The vendor image and rom flashed in the bootloader right ? Here is the rom and factory image the same ?

I tend to use fastboot rather than twrp for flashing images (.img files). See this thread for more info, it will give you a good overview of flashing stuffs and you'll catch up with the terminology as well.

You are right about it being easy after reading up. But its just that i;ve tried just about everything and the baseband version just does not show up in the phone information (also no IMEI), even though it shows up in the bootloader. My wifi weems to be working fine but still shows no sim.
Starting to think this may be due to simething other than the radio .
Tried the initial suggestion from the 1st reply using the commands to wipe the partition with no success, then flashing radio, vendor and ROM from the 2nd suggestion no success here either .
Not sure what to do anymore

No, through adb. Boot into recovery and then
ADB shell dd if=/dev/zero of=/dev/block/platform/soc.0/f9824900.sdhci/by-name/modemst1 bs=16384

Maybe its due to some other problem and not the radio since the wifi is working.

Hi, I seem to be in your same situation, no network after trying the radio flashes, resets and reboots.
Did you manage to find a solution for this issue?
Any help would be appreciated. Thanks

Google logo bootlooping, recovery not working either

Hi everyone!
I was using Resurrection Remix ROM on my 6P, no custom kernel and TWRP 3.0.2-2 installed. I installed the ROM by going back to stock, reflashing the recovery, and installing ROM + GAPPS - I like my ROM installs squeaky clean, never had an issue. I set up my phone and moved in completley. I went on with my day until around 11 last night where I was rebooting into recovery to do a TWRP backup the phone just never booted. I rebooted bootloader and tried again but I kept getting the Google logo and the device rebooting. Then again Google logo and reboot. Never showed the TWRP splash screen.
I then went ahead and tried returning the phone back to stock. I downloaded the firmware from Google (latest Nougat), put the phone in bootloader, and began the installation (using flash-all from the zip file). Everything seemed like it installed fine (no errors) and the phone reboots. Same issue, Google logo and a reboot. I tried going into the stock recovery, but no dice - Google logo, reboot. I reflashed TWRP to see if maybe that'll work but it didn't (Google logo, Reboot, rinse and repeat).
I relocked the bootloader and for a split second I saw the "Erasing" with the colourful hoops then a reboot to the Google logo - never booting into the fresh install.
Fastboot responds and detects my phone, I have opened the phone and the power button isn't stuck, I have tried going back to MM stock (installs but no boot).
Is there anything else I can do before going out and buying a new phone?
Thank you!

It's been an ongoing thing with the 6P's and 5X devices. Here's a thread that might be able to help you. I myself fell victim to this and nothing i did brought it back to life. Wound up doing an RMA with Huawei..

THANK YOU for shining some light on this issue! Looks like my phone is under warranty till 05/2017. But my next question is would the warranty be voided because I opened up the phone to make sure the power button wasn't the cause of the issue? :| I hope not!
Thanks again!

Absolutely, yes. Your warranty is void. That's always going to be the case on just about any electronic product. The only exceptions I know of are upgrading the hard drive in your PlayStation or Xbox, since you don't actually have to dismantle the entire system. They make the hard drives easily accessible without having to open anything else. As far as phones go, opening them will always void the warranty. They can tell as well, so you can't get a warranty replacement. Hopefully those links provided can help solve your issue so you don't need to pay out of pocket for a new phone. Good luck.
I had this problem when nougat previews first started. This is what worked to get me back up. I guess it erases the efs partitions and forces the phone to rebuild them. I tried fastboot flashing stock, etc, nothing worked, then I ran these two commands and it booted right up.
adb shell dd if=/dev/zero of=/dev/block/platform/soc.0/f9824900.sdhci/by-name/modemst1 bs=16384
adb shell dd if=/dev/zero of=/dev/block/platform/soc.0/f9824900.sdhci/by-name/modemst2 bs=16384

how did you get adb to work? The phone does not go into recovery mode, always bootloop.

Where did you purchase the device from? Try Huawei again, maybe you'll get a different rep.
Amazon
I had a very similar problem. In the end, I used WugFresh's Nexus root toolkit to flash stock Nougat, with 'current status' set to 'soft-bricked'. That worked fine, and I'm back to normal...

I'm a try but not work
I spoke with Huawei and as soon as I told them about the issue they right away were going to give me an RMA. I told them that the phone received an update from "google" and when I restarted the phone, the phone started to bootloop and never booting back to the home screen. But before we proceeded with the RMA I had to tell them the bad news - that my phone was opened because I was suggested to check if the power button wasn't the cause. She said that that voided the warranty and that my phone wont be covered for any repairs. I asked if I can pay them to fix it and they said no.
All in all I have a very pretty paperweight sitting, waiting to see if someone can come up with a fix. For now I'm using a Blackberry Passport with my android apps installed.
If not I'll either be moving to a OnePlus 3 or OnePlus 3T.
P.S. the toolkit "Soft-brick" option did not work for me either.

Nexus 6p stuck on Google logo

I need your help, after upgrading to 7.1.1 the phone is dialed and restarted all the time in this way.
I would appreciate a solution, I leave an exact example of what happens to me.
OEM is not unlocked and debugging mode either because I can not start the phone
My problem is that it does not unlock OEM and I was not active debugging, the phone just let me enter Fastboot but at the time of choosing RECOVERY it restarts

Dude try Nexus toolkit my Wugfresh (NRT Toolkit) you have to boot to bootloader and use the application to clean install
I have this same problem. flashed MegaPixel6P, tried using the camera, and then my phone shut off and just keeps rebooting. i think /data and /system are corrupted. any attempt to nandroid backup or restore fails and causes TWRP to reboot.
Alot of users are facing this bootloop issue. So far no one has been able to figure out a pattern that will give us insight into what kind of devices might be affected by this issue. I have created this survey on GoogleForums so far there are very few responses. Please participate to help the community figure out the probable cause for this bootloop
https://docs.google.com/forms/d/1nGAVdnjbkOE1ohvZvqbntb_7afT4p2OzbFIJjJWiy9Q/edit?c=0&w=1
BTW what's your phone's manufacturing date? were you using Magisk or SuHide?

If you can get to TWRP, you can just reflash via fastboot (or use NRT). You may be able to apply your TWRP backup afterwards if it is not corrupted.
As for OP, if the bootloader is locked, and "Allow OEM Unlock" is toggled off, your options are slim to none. If this setting was enabled before upgrading then it is still enabled. If it was not, you cannot unlock the bootloader.

Have you tried FORMATTING boot, system, data & vendor and then reflash? Format, not erase/wipe. Move your TWRP backup off to PC and try that. If you are rusty in ADB/Fastboot, then use NRT to do same in advanced tools. If you have a working recovery and your bootloader is unlocked, I would not give up yet. Good luck!

Yeah your problem is a bit different that others and it's worth investigating.
To verify your complete emmc, you could try this command in twrp -> advanced settings -> terminal.
dd if=/dev/block/mmcblk0 of=/dev/null
Basically doing a read test by copying the complete mmc to the void. It should give you a status at the end that you can post here.
By the way, the recommended factory flashing is by using flash-all script that is inside the factory image itself. And you need the latests android SDK.

nope. i enter the command and it does nothing for about a minute before turning itself off
also, im not some complete n00b, so trust me when i say i've tried everything. any time i restore a backup, once it starts applying just /data or /system it'll shut off and bootloop without finishing.

You never know the level of the person you're talking about eh. Just tought you hadn't tried the dd.
So dd shutting down before completing wasn't expected but now if I read again your posts, you said doing a photo shuts down the phone and that's quite typical of power related problems. Sh*t.
Could be the battery not holding discharge. Can the device stay in twrp with screen off? Did you try to let it fully discharge and charge it with a slow charge?
There are a lot of information in /sys/ or dmesg but it won't solve your issue.
Still under warranty?

Forget restoring your backup for now. You're not a noob, so transfer your TWRP backup to PC, then FORMAT each partition first, including userdata and then reflash using a Google Imagehere. Ensure you are using the latest version of ADB/Fastboot. You didn't mention you have already attempted to Fastboot flash the NMF26F image. What was your result then? The reason I'm asking is that the Google script erases the partitions- does not format, but running the script will tell you which partition failed during writing.
Huawei Customer Service!!
Had the exact same problem creep up on me this past weekend. I ended up calling Huawei and they are doing a free warranty repair on my phone even though I'm almost two months out of warranty.
Make sure you are on SDK 25, I had the problem synonymous. I have been hunted at Huawei and only when I had already given it I realized that I was not on SDK 25 and I know of some others that was the reason with most.
Whether it was the reason with me, I know tomorrow, the device is back and can be picked up,

Yes, the latest ADB / Fastboot is required. The rest of the SDK is not mandatory. You can get a minimalist ADB-Fastboot-Driver install from an XDA dev here.
Also, TWRP updated for Angler recently here. This update solved a persistent backup problem I had with the previous v3.0.2-2
bought it second hand, and the previous owner bought it at launch, so im just a month or so out of warranty. im trying to get the original receipt to attempt to RMA it. Huawei's IMEI lookup says its under warranty till april 4th next year.

Was your phone stuck in Bootloop of death as well? How did you fix it? What do think causes this issue and how can it be avoided?
