[Q] So I know this has been solved/asked before but... - G2 Q&A, Help & Troubleshooting

Being the noob dummy that I am, I was not paying attention when I was clearing out my caches and happened to deleted -everything- from my phone, system included. There is nothing left on my phone except for Recovery. I managed to flash back to before I deleted everything (good thing on my part remembering to flash everything again).
However, I am still stuck with these white lines going across my screen. I have read the fix for this, but I am utterly lost in how to actually proceed. =(
I was hoping someone would help me out with this barney style.
Anything and everything is appreciated!
EDIT: I've gotten to where I go to the downloader on the phone, but I am having immense issues with ADB as far as flashing the updated kernel onto my phone as fastboot does not recognize my device, or sometimes ADB has multiples of my phone on the device list, which makes the program inoperable.

If you have white lines in system after screen off you must flash a patched jdi kernel. Search little kernel flasher for kernel patch

That little program is a damn life saver. Very convenient. Not sure how I missed that in the search function?
Anyway, thank you very much!

I think I bricked my nexus (my fault) please help!

Hello all,
I think I may have bricked my nexus one. It is completely my fault for attempting things that I knew little about, so flame away But after the flaming, if anyone is willing to help I would be sooooo thankfull...
I successfully rooted my phone following the instructions on this page: (all links edited with a double asterisk as I don't believe I can post links)
h**p://theunlockr.com/2010/01/02/how-to-root-the-nexus-one/
Then successfully installed cyanogenmod (which is awesome!) following this page:
h**p://theunlockr.com/2010/01/08/how-to-load-a-custom-rom-on-the-nexus-one/
All was well, I even got the modaco desire rom up and running, and was happily switching back and forth using the recovery screen. I had nand backups for specific setups, etc.
Then I decided it would be good to know how to go back to stock, and found this page:
h**p://**w.androidspin.com/2010/05/06/guide-unrooting-your-nexus-one-its-like-it-never-happened-almost/
I followed the instructions to the letter (I think) except for erasing userdata (it said "failed: remote not allowed"). I thought that things would be ok, since I'd recently wiped, so I followed the page till the end.
The phone rebooted, and I got the original nexus boot animation - but it's in an endless loop! What's worse, it that now when I try to go to the bootloader or recovery mode, I get the exclamation triangle with the little android.
Is there any way through a command prompt (or other method) that I can fix this? I tried to re-flash the RA recovery image through the command prompt, but the response was, "waiting for device."
ANYTHING that anyone can suggest to help, I would be so thankful! I've been loving the nexus, and hate to think that I crippled it
Thanks in advance,
Randy
I doubt its bricked.
Noticed you didnt mention that fast boot doesnt work? (power button+trackball) try it.
Once you get to fastboot you can flash any ROM back. (fastboot flash **** commands from a command shell)
Did you ever perform a Nand Backup from Recovery?
It's not bricked, the only way to brick is to interrupt power when flashing a Radio image
Connect phone to PC. Open command prompt.
adb reboot recovery
Wipe, reflash.
So far, nobody has managed to brick a Nexus. There is no way as the fastboot mode can restore the whole phone and can't be messed with. Make sure you have the latest version of the SDK with correct USB drivers and fastboot. Then try and reflash the recovery image.

It worked!!
britoso, thank you soooooo much! The only way that I knew to get into bootloader/recovery was via power button/volume down, but power/trackball brought up the bootloader screen, and I clicked on fastboot. I was able to flash the RA recover image through the command terminal via fastboot, then able to get into recovery. I had cyan and modaco sense on the sd, and was able to flash one of them on.
​
I never thought I'd be so happy to see "quietly brilliant"!!! I WILL buy you a beer, a case in fact as soon as money clears my paypal account.
I have learned my lesson, research research research. (I did do some, but not enough to feel comfortable with what I was doing - hence my cry for help!)
Other than the phone and OS itself, the thing I like most about the nexus is the fact that one CAN root, and then customize (sold a Telus moto droid because I could not do that very thing).
I digress... thanks again so much!
And Paul, thanks for your sense ROM; I've had HTC phones from the Touch to the the diamond to the Hero, and missed the UI!

Glad to hear it. You learn the most by trial and error.
I think i got the same problem. i tried to Unlock Bootloader and Root Google Nexus One which was successful but then i tried to superboot it and when it came to the part where you "double click the ‘install-superboot-windows.bat’ file" i clicked it but it did not go to the nnext screen where the superboot completes it just stayed at the "bootloader screen". i must hve not done something or done something wrong i dont know.
So then i unplugged the phone from the pc and rebooted it. when it reeboted i wasnt getting any network, the phone was slow and the notification bar would not slide down...also i noticed the phone restarting on itself...
/i tried all kinds of "restore to factory settings" but not solved. Can anyone tell me what to do tht will work. I coud not understand what was said in the above thread as i am new to this android n my first time rooting n stuff n i believe that solution would work for me too..if some one could please explain in simple tirms the steps i need to take would be good...
Really appreciate it....

[SOLVED] Phone reboots to recovery, even after TWRP restore?

*I flashed a CM12.1 nightly on top of one that was a couple days old, and the new one had all kinds of force closes. This was through CM's internal update function, which sets a recovery script and reboots into recovery to install it (which BTW failed).
So I went into TWRP and flashed the backup I made not a couple hours earlier. But now I have kind of a bootloop. Most of the time, the LG logo shows up, then it just reboots back into recovery. One time it got stuck on the logo, and I was able to see it with ADB but it told me init.sh was missing when I tried to adb shell into it.
I have three backups I tried restoring, which had /boot, /recovery, /system and /data, plus I wiped the Dalvik cache and /cache, but nothing I've tried will kick this thing loose. I've even tried formatting it back to EXT4 from F2FS, and erasing and recreating the partitions in fastboot. It seems like there's a flag somewhere telling it to reboot into recovery, but I can't find anything pertinent online. I'm really at a loss as to how to fix it, and out of ideas now.
Have you tried using the lg support tool to bring the phone back to stock?

Yeah, I was going to edit the OP to say I've also now tried to flash back to stock, using the 20a KDZ and the LG Flash Tool 2014. When it gets to the point where it's actually about to flash, it says "USB is not connected". I have all the latest drivers, and have tried different cords, to no avail. It has been transferring files while connected in TWRP, so I'm not sure what that's about.
What about using the lg support tool to flash stock?
LG Mobile Support Tool is what LG Flash Tool calls to actually flash the ROM (otherwise you have to depend on what LGMST decides to download). It saw the phone the last time I used it, but wouldn't show LP 5.0.2 as being an available update, even though it had been released.
This thread has the instructions I've been working off of, which was posted around the time the ROM was released. It "should" work, it just doesn't. If I'm not mistaken, there may be another tool you can use, but I haven't been able to find it.
There's one other way I suppose I could go about this, but it would be delicate. I could push all the individual IMG files from a ZIP archive I have of the KDZ, but I don't know what all the partition names are, and there are like 10 of them, including laf, aboot, etc. For example, the /data partition is actually named "userdata" when you use fastboot flash.
I didn't know about the difference between the LGMST and Flash Tool.
All I know is that the LGMST was able to download the correct LP ROM for my phone, install it, and get me back to stock after I screwed things up when trying to get root.
i have same problems , here is my solutions
- use SKR tool -> 4 .fix utility -> 5.unbrick ,
if u want go back to stock, try use TOT file to go back JB
cant use kdz way

+Thanks, I have never even heard of that. But I'll give it a try. By any chance were you using F2FS?
Though I am not sure, but I'm leaning towards some kind of hardware failure -- this is a refurbished phone, so there's no telling what it's been through inside. T-Mobile sent another one overnight, which I should have in a few hours, but I still need to clean up this one if it has to go back.

Mine told me I had the latest version, which is peculiar. Was your phone rooted at the time? Because I could understand it refusing in that case: I ran into a soft-brick on a D800 because of an OTA once. Otherwise, I'm not sure why one would work, and the other wouldn't.

The reason I ask is that I had a debate in another thread about using F2FS instead of EXT4 for the filesystem. Most people suggested it's buggy and causes problems, so I wondered if that's what happened here.
When I used lgmst, my phone was giving me boot certification errors. I played around some more with it and then it would only go to download mode.
I connect the phone in download mode and the program downloaded and installed the latest LP rom for my 802 from UAE.

I wish I had a D802 -- it's ubiquitous, and thus has more support on XDA, I think. I'm not sure why T-Mobile chose to have a customized model. Same goes for AT&T, since they both use the same frequencies... and I don't know what the hell Verizon was thinking with those hideous buttons. The only differences I see between most of them is the SAR.
I am not sure that all g2 phones support the same frequencies. My 802 will not connect to LTE in Canada.

Well, they don't, especially Verizon and Sprint being entirely incompatible because of CDMA. I looked it up just now, and while there are several variations of your phone, it actually looks like it has a lot less frequencies than the T-Mobile device. I was under the impression it was the other way around, but I dunno exactly -- yours is supposed to be a D803 up there. It depends on the carrier/region, and which LTE bands they're using. It may be that you get LTE somewhere else eventually.
I don't know why the hell they don't just make the phone with all the bands you expect to encounter on a continent, but I'm sure it has to do with lock-in. Because the SoC should already have that stuff baked in.
I actually have an 802 (International version, unlocked) that I bought off a guy on Kijiji. It was an incredibly cheap price because it had some scratches on the screen which are not very noticeable. Once I applied a tempered glass screen protector, you could only see the scratches from an oblique angle. The guy even included an official LG flip case which wakes and sleeps the phone This phone even has a stock LP ROM.
I love the glass protectors! That gel adhesive just melts on the screen and leaves not a single bubble. And yeah, it gets into scratches and improves them, too. I'll never use film ones again. I've personally never broken a screen, but Gorilla Glass can be scratched under the right conditions. Hey, as long as it's working for you, cheap is always good. HSPA+ isn't anything to sneeze about either -- I've had some amazing speeds on T-Mobile with it, for years now. It's a great fallback for LTE.
Okay, I managed to recover the original phone!
Something in my previous build was triggering the boot loop into recovery. This happened when the CyanogenMod updater tried to flash a new nightly, so there's a possibility it set a flag that kept it looping. But it's also possible Xposed went haywire somehow, and/or a module did. I'm not really sure why it decided to fail like this, when I had been using it without issue.
All my backups did the same thing, yet those builds ran okay when I backed them up. And I don't know why I could see the COM41 port, but not use it -- the drivers were perfect, I went to a lot of trouble to uninstall and replace them. That meant no LGFlashTool, and manual restoration (ye olde commande line).
So, what I did was use fastboot to flash every partition I could get my hands on, not just the ones you can format in TWRP. I used the 20c files from here. You basically do:
fastboot erase aboot
fastboot flash aboot.img
fastboot erase laf
fastboot flash laf.img​...etc. Then you format the /system partition, and flash a Cyanogenmod nightly into there. I also flashed the /data partition, but left /data/media alone, which saves the internal storage. Then I erased and flashed /recovery just for good measure.
This is a somewhat specific fix, but maybe if someone else comes across it, it can help.

D802+JDI panel. how do i install jdi kernel when i cant even see the recovery?

Hello
Im just recently bought this device from a friend so i could ditch my broken Galaxy S2. I just need a good looking phone that does the job without lag and is unrestricted in terms of access which means, i want to be able to install custom roms. Oh and screen size is also important to me.
I however am NOT new to the android modding community and ive created a couple of things myself, but for every new phone im forced to relearn almost everything. Aaand boy did this phone land me in a very awkward situation that 6 hours of pure googling, experimenting with different firmwares etc, couldn't fix.
I learned the hard way that i have a JDI display and that its less common than the other one. I followed some simple guide where i was on 4.4.2 already and basically rooted it with ioroot. Now the only method ive found so far to install a recovery on a stock 4.4.2 lg g2 (d802) 32gb edition is by using a certain application called autorec.
I did try it. It seemed to work. No error. However, to my suprise i found out i had a screen that was completely covered in white/green/blue lines. By how the procedure was supposed to go, the app was supposed to boot me to twrp recovery after the install. And im guessing it did because i could feel the vibrations of the different buttons as i tapped the screen on different places. But i couldnt see what i was doing.
I researched into it and found out about the whole jdi thing. Found a Europe Open D80230b.kdz firmware and flashed it but just blindly booting the phone into download mode tho it was still covered in lines and couldnt see a thing. Once it was done, the phone booted and the LG logo was visible and the lines started to decay and slowly dissapeared. after about an hour, they were totally gone.
Now to the main issue im having and the question i have for you if can help me.
How do i go about installing a recovery that works (that i can actually see) so that i may access the menu in order to install this ldi kernel zip? Ive tried installing a recovery with the one click root + recovery script by somboons.
It gets stuck on this part "author : blog.lvu.kr
SPECIAL COMMAND : ENTER,LEAVE
#"
I basically CANT install a recovery on 5.0.2 with the one click script because it gets stuck. Cant root it either with SRKTools. I CANT install recovery on 4.4.2 with Autorec because my phone gets covered in white lines and i cant see what im doing. I tried installing a certain jellybean firmware to go from there. Using the open europe d802 jellybean firmware wasnt possible because the flash tool kept giving me disconnection errors. So i tried installing a open polish d802 firmware. got white lines so that is a no go too. One thing that i suprisingly can do. I can root it using the LG one click root method 1.3. The 1.2 script cmd version doesnt work. It gets stuck on the special command # part, however the graphical interface version roots without any problems.
ive found the recovery im gonna use which is supposedly nicer to jdi screen that, according to the creator, is supposed to generate less heat on the jdi screen. however i dont know how im supposed to install it. For now im gonna use the 5.0.2 open europe d80230b firmware til i find a solution. All im trying to accomplish here is to successfully install CloudyG2 3.3. And open the doors for a potential cm13 install.
Finally reached recovery by using this app.
https://play.google.com/store/apps/details?id=wli.areclp802
Read description on whats required if you intend to try it yourself. It requires root and some SuperSU option unchecked. Worked perfectly on my LG G2(D802) with JDI display that ran 5.0.2 lollipop stock firmware 30d. It will flash recovery successfully but then i had to manually press the button inside the app for it to boot me to the recovery. its the newest twrp 3.0 recovery. Now im happily running CloudyG2 3.3
This question thread can be closed now!

LG V20 H910 Root attempt fail, any plan of recourse?

Hi. I'm just gonna say this first: I didn't know entirely what I was doing when beginning this operation. I was just trying to do something fun and new, and it didn't pan out. I fully acknowledge that I am an idiot.
Now, the story. I was attempting to root my LGV20 with this guide: https://forum.xda-developers.com/v20/how-to/root-h910-v10m-t3664500 .
I have read over this thread more times than countable and thought I was doing everything correctly. I got to the "STEP3.BAT" portion of the guide and long story short, my phone crashed during it and somehow got foobarred.
It *kinda* works (as in it will boot for around a minute) and then blue/black screen into a reboot.
Is there any way I can save this phone? Hard resets, going into software, more dumb computer stuff, anything. I don't *need* to get this phone working again but it would be really preferable.
Simultaneously I fully accept the responsibility in failing the operations. I know that somewhere I must have messed up. If no-one wants/ can help me, tell me so. Just means new phone time.
If any more detail on what happened is needed, tell me.
First off: that guide is ONLY for the H910 (AT&T) variant, so make sure with your model
and also, when you said a "blue or black screen" it also has very small writings too, right? If so, then you may have faced a kernel/bootloader panic
Technically your phone is *still* alive, and your best method is to start over again, assuming if you read the whole guide carefully then you have backed up your firmware and can still access download mode.
Flash your stock firmware back (or use the H915 firmware provided by the guide), wipe and setup your phone again, then root the phone again.
I also suggest replacing the TWRP recovery inside the provided Dirtysanta folder cuz that's what i did when i faced the kernel panic

Thanks so much. Freaked out over this for a good bit. Came back, did what you said and we're back at that step fully working. Life saver.
Now my first guess as to why step3 failed is that i didn't have the latest version of TWRP. How can I set that up?
Inside the root package folder you can see an .img file named twrp 3.0.2-1- us996.img
What i did was downloaded a later version
(not latest cuz my phone won't boot at the latest version for some reason), copied the name of the original twrp and renamed it, paste it to the folder, overwrite the old one, and try to root it again

No i don't think there is more things to do, the guide you're following is pretty much straightforward already.
100% guarantee is always a stretch here in XDA. But if you're still facing problems you can ask for help on that guide's thread.

I really want to give up on this. This time I successfully made it through all Step 3, but I also noticed that my screen was kind of glitched and not rendering properly at that stage. After it rebooted, I unplugged my micro usb cable and it gave me an angry green warning message I will attach here.
If you/someone can tell me what to do with this message from here or instruct me on how to flash stock H910 10 q back onto the phone without doing TWRP (since i'm evidently incapable of installing it) I would be most appreciative.
Slightly better picture without anything cut off.

The screen glitching is normal, the green text after boot however is somehow not.
Sad to hear that it still didn't work, there something seems to be interrupting the process of rooting your phone. I dunno if it has something to do with ARB (anti rollback) preventing you to root
If you want to go back to your stock firmware that you backed up, you can:
-Carefully flash each file of your backed up firmware through adb and fastboot mode
-build a zip file of your firmware and flash through TWRP (since it didn't succeed tho)

Unfortunately i can't find any guides when it comes to flashing the back up.
I did read something back then on turning it into a zip file, but even if you can build one you still need TWRP, in which case you haven't successfully installed, so that's no option
Flashing the backup files requires specific commands, especially to the part on what partition should it be flashed to
When LGUP backs up your phone's firmware, you can see a vast number of files(i can't remember how were they named, I'll look up a reddit post about it)
The files where named based on what partition it came fom (H910_modemxx_COM12, H910_system_COM12 or something like that)
These are image files, what i did as far as i can remember was rename these files by adding an IMG extension for ADB to recognize
Flash them according to it's partition name:
"Fastboot flash system H910_system_COM12.img"
"Fastboot flash recovery H910_recovery_COM12.img'
Etc.
To go to fastboot, turn off your phone and hold the volume down button , then plug your phone to the PC.
But i really cannot guarantee this, because for all i know, in order to flash this you need fastboot, and to get fastboot you need to root your phone, because only the engineering bootloader has it (i'm sorry if it's wrong tho), and flashing these files to fastboot might be a bit dangerous because it will not verify the files, there may be chances that you might flash a corrupted file. so flashing via LGUP is the safest option so far if you don't know what you're doing

6T keeps 'crashing'

So I just picked up a clean used International 6T. Was going through the root and update (I did the Android 10 update through Oxygen Updater) process and all that, things were going great, then out of nowhere they weren't and I had a complete black screen. I've literally been up all night trying to fix this thing, then again out of nowhere it actually boots, and I was able to use the MSM tool to restore it to that earlier version, then proceeded to get back up and running again.
Thought, phew, dodged a bullet. Nope, after getting rooted and TWRP installed, transferring a bunch of files over from my old SD card and restoring apps through Titanium (again, everything was going great again), and yet now all of a sudden I'm back where it all started earlier, stuck at the 'The boot loader is unlocked and ....' boot screen, it just hangs there, I can reboot into recovery just fine, but no operating system.
I'm literally about to pull my freaking hair out and try and sell this thing if it's going to keep doing this, I've never had a phone act like this one has (prior phone was a Nokia 8, headache). I have friends/family who haven't heard from me in a couple days now because I'm out of a phone and I need to get this thing working stable.
Can anyone help or shed some light on why this has happened again? I didn't update to 10, left it on the last stable Pie (begrudgingly), didn't flash any custom rom or anything, it was restoring most of the titanium apps just fine (some just hang there, not sure what that's about) and now I can't reboot into the os. To say the least I'm beyond pissed and annoyed at how much time I've lost on this thing.
Please please please help if you can, I'm not a newb to rooting (already rooted this one twice) but I don't know what to do at this point.
Thank you in advance, let me know what/if any info is needed.
Edit: I think I know/understand partially that magisk is to blame for this and reinstalling it fixes it, though I just did that through TWRP and it's still stuck on the boot screen.
Edit: Yup, right back where I was, device now shows as HS-USB QDloader..... in device manager. What gives? I have to use the MSM tool again? Why? Why is this happening...I've never had this much trouble with a phone
Try a clean install. Don't root and don't restore the titanium apps. Install them fresh. If your problem persists then it may just be hardware. But something you are restoring may be causing the crash due to the way it is trying to restore the app data.
I had similar problems. For me it was my self-created magisk module that ran without problems under Android 9. As it seems, there are also problems with modules from the magisk repo.Could be the case with you.
Clean install of the apps, after doing another MSM restore? And trust me, I won't be installing ANY other magisk files other than just the magisk.
Is there any way to save all the work I just did though without having to start over again via MSM? I'm guessing not....sigh
Grrrr...ok before the MSM tool worked, the phone was just unresponsive. It's back at that stage where the MSM tool times out and doesn't do a darn thing to save the phone.
I swear this thing is all over the place, now I'm in the bootloader, yay. I guess I'll try a wipe in TWRP and start over.
One thing I forgot to ask, is magisk the ONLY option available for root?
The question would be, how did you root.
TWRP is not working when you don't follow the instructions which involves OldKeysFlasher.zip.
Otherwise you have to flash Magisk with a patched boot image, be sure uyou have one for OOS 10 Stable.

I hope that anger is directed towards yourself because you can't hold the device or its manufacturer responsible when you get into the flashing game.
If you had done some reading, you'd know that TWRP doesn't play well with Android 10 and upgrading from 9 takes a very specific procedure. There's a dedicated thread for it even. Happy searching. You may also want to take a peek at my posting history for some pointers.
One more thing, are you absolutely sure it's an international device and not a converted T-Mobile version? Because that can cause a major amount of troubles.

I'm well aware it's my own doing, part of the frustration is having too many sources of information all claiming they fix a 'thing'. There's the "fix it with fastboot" camp who doesn't like MSM, and there's the MSM camp that helped me the first time. Phone is currently dead/black screen, going to try MSM again, and will check out the info you provided.
And I'm sure, double sim tray, does not flash a pink tmobile screen and/or no branding of any kind on the phone related to tmobile.

Just remember that dual SIM trays are easy to get and if it's been converted from TMO to international version there will be no indicators till n you try to flash A10. Best bet would be to treat it as a converted TMO, if it is the info in recovering and flashing a TMO device will work and if it's truly an international version it will work too. Best of both worlds.
I'm 99% certain, by the label on the box, etc. Regardless, I'm to the point now that I can't even get it to boot to TWRP after 'fastboot flash boot twrp.img', it just does nothing and when I try to boot to recovery it bounces right back to bootloader. I've been trying all afternoon to fix it with no luck.
Was android 8/oreo good on these phones? That was my sweet spot and I'm just gonna downgrade if possible, there's too many things I don't like about 9 and 10.
