[Solved] [LG G4 H815] Stock MM stuck on logo screen after stability update - G4 Q&A, Help & Troubleshooting

Hi guys,
this is the second time that LG bricked my phone. I updated my g4 and now it won't boot up anymore. Installed was Android 6.0 and the last security patch was from 2016-08-01. Software version was V20h-EUR-xx. I already had the fun of having the famous bootloop and a screen burn in, so i basically got a new phone in early 2018. Mid 2018 i got the notification of a software update (it said something like stability update and was just 50 MB big) but I didn't have the time to back up my stuff properly so I delayed it till yesterday. Two days ago I was preparing myself for the upcoming android 11 devices, so I saved my photos etc and got most of the stuff out of my phone, then I did a backup through the onboard app (LG bridge won't recognize the phone most of the time and if it does it tries to save the backup temporarily on the phone, which didn't work because of low memory space(on a sidenote wth is the g4 doing with all the memory space anyway)) and saved it on the sd card. After that I updated the phone. A screen appeared with with software update process (1/2) and (2/2) and both completed succesfully. After the reboot it got stuck on the LG animation logo, this is a screen right after the "lg powered by android" screen, and it is stuck there since. I tried to get into recovery mode but was unable to do so.
So yes I have a backup, but afaik no user data gets saved in the app backup, am i correct? This is the reason why I haven't tried to hard reset yet. I thought maybe some bright minds in this forum know a way or solution to this problem.
I have read a little bit about LGUP and TWRP but i don't know if this will help. And i don't know which firmwire i need cause there is a bunch with H815.
What I'm asking is, is there a way to restore the phone without losing my data that is still on the phone?
sry for the long text, let me know if you need additional info
greetings Johnny
tl;dr: LG is producing garbage, please help

UPDATE 1
I was able to get into download mode.
Plug the USB Cable into the PC(not connected to the LG G4)
Have you PC Powered On and Logged in
Power Down the LG G4
Press and Hold the Volume Up Button on the LG G4
While Holding Volume Up, Plug the USB Cable into the LG G4
Continue Holding the Volume Up Button After You See ‘Download Mode’
Let Go of the Volume Up Button When You See the ‘Firmware Update’ Screen on the G4
Right now I'm trying to do the update via LG Bridge and the download mode.
Funnily the update is now 1,68 GB in size while on the phone the size was roughly 50MB iirc.
My free memory space is only about 4GB, so i hope this will suffice.

UPDATE 2
The installation was sucessful but only on my second try. The first time it failed at 81%, so I did it again as I was told via LG Bridge and followed the instruction steps. The second time it worked. After rebooting I got the screen that 80 apps are getting optimized. Took nearly 40 minutes. After that I got in and did a quick check if everthing was alright, saw that some apps weren't installed, so I restarted it and the rest got optimized. Power off again, sim and sd card plugged in and power on. Now everything seems alright and if I'm not mistaken battery life has improved.
So in the end it was a failed update caused by LG and fixed by LG Bridge.
BUT in the meantime I contacted LG customer support and it turns out customer support is on par with their update policy, non existent!
Talked to a guy who didn't understand what I wanted from him, so he gave me a number where I could call. Called there, turned out it's the company who repaired my phone when I had the bootloop and screen burn in. After asking them about technical support, they told me they don't do that, they only repair. I understood, so phoned LG again. The same guy picked up again (is he the only one there?), so I asked again. This time he googled my questions and told me he can't find on google what i'm asking. I thought he has to be kidding but he was serious. No blame to this guy though, he is first level support and obviously not qualified to answer such questions, so I asked if he could redirect me to someone who could answer my questions and help me. Therefore he let me wait in the line to call a colleague so he could tell him my problem and then told me the answer of his colleague. I wasn't satisfied so I insisted to talk to this colleague of him, he said it wasn't possible because of technical reasons, but he phoned his colleague and but both phones together so we could talk (wth haha). Needles to say I didn't understand anything and I was absolutely bewildered about what was going on and the state of the LG support. I tried to convince this guy the he was of no help to me so if I just could call this other guy or be called by him would really help me. Finally he understood and gave in. He wrote down my number and five minutes later the other guy called. Well he was of no help either. Couldn't really answer my questions but could at least explain two things of interest to me. I am still shocked of the state of the LG "support". Don't they have guys who know their products and their software?
Thankfully everthing is fine now and I definitely know that I won't buy an LG smartphone ever again.
(The camera and the screen were really nice though)
greetings Johnny

G4 Bootloop

Hi Guys,
i am really confused and a little bit angry. The Following happened to me today:
My Phone (Unrooted, Locked BL) was behaving weird this morning.
It just randomly crashed and wouldn't boot up.
Eventually i got it to boot once or twice, but still it crashed, shut down and Bootloop.
A Reqular Factory Reset did nothing. now i'm trying to install the Regular KDZ-File for the H815, but things are just not working as expected.
Has anyone else had this problem before?
Is it normal that the LG Flash Tool is on 1% for over 5 Minutes and nothing changes on the Phone screen?
I want to know what has broken my phone so bad, cause this time, I just used it the way it was supposed to be used, no hard drops, no rooting, no changing of software in any means.
First LG Phone and it broke with no warning and no explenation. I'm a little disappointed right now.

The same happened to mine. Are you able to get to download mode by powering off your phone and plugging it into your computer? Im able to flash stock ROMs but nothing helps. The phone reboots by itself at random times and makes it into the operating system a few times but is never usable.

Hey,
yes i can get into download mode.
I am able to flash files, but the phone wont boot up anymore.
I just want to save my data, but i guess i wont be able to do so.
So i have to get to the store and get a new g4
Luckily i made a backup of my two weeks ago, so not much will be lost.
I also send an email to the LG customer Service, will post their reply here too.
I am really disappointed by LG at this point, i usually had motorola phones and they didn't have random errors like this one.
I switched to LG, cause G4 sounded awesome, but this error is making me sad.
I am really thinking that i won't buy another LG Product, which is making me sad too, cause usually most things made by them are great.

//==============First Request by me:======================
Hello dear LG-Service Team,
i just bought the premium product LG-G4.
Since some days, the Phone is beginning to hang and reboot, resulting in a bootloop.
Sometimes the phone boots, than optimizing Android for about 30 minutes (100+ Apps installed). After this happened, i kann use it again, but not fully.
To shortcut eventual questions:
The Phone is in factory State, no Custom Rom installed. The bootloader is locked and the Phone has not been rooted.
The mistake seems to come from your firmware.
I am really disappointed, because i paid a lot of money and no have a product which is barely usable.
I switched to LG because of the G4 and i don't want to regret this decision.
Kind regards
<<Esok>>

Email and response, translated by me, so there might be some mistakes...
I don't like the response, it feels like not being taken seriously.
Well, nevertheless, i will go to the retailer and will see what happens.
I will keep you updated.
What do you think of this response?
Greetz Esok
That response is terrible lol. I called in and they said they do not support my phone because it is an international version. So there was nothing they could do for me.
I have a similiar issue, but mine was due to a OTA update, and I didn't know about the download mode until now.
Thanks.
Any tips when I can get into the download mode? I just wanna recover my personal data (images, and texts)? Flashing STOCK image would preserve the personal data right?
While your phone is off, plug it into your computer while holding volume up. If you are using LG flash tool to flash a .KDZ firmware file, you will come across an option that says Normal flash or CSE Flash. Normal flash will not wipe data, while CSE Flash will. I have flashed stock images and it didn't work. Hopefully it works for you though.

+1 I'm in same boat and exact same issue with my H815. I love the device but this is unacceptable.
I'm having the same problem, it just happened to me all of a sudden and now I can't even get to the boot animation. I've been able to get into recovery 2 or 3 times but usually it just restarts before it even gets there. I recently updated to the newest xposed framework (though I've restarted just fine a few times after I installed it), did anyone else here do the same?
When I get home from work I'm going to keep attempting to fix it, I've flashed my current TOT but it failed after rebooting. I don't know if I'm having the same problem as everyone else but I'll update if I can find a solution.
same issue here on the at&t 810. Starting about 3 days ago I started getting random reboots + bootloops. Sometimes it would boot to the LG logo and stick, sometimes to the AT&T logo and stick, sometimes to the OS and freeze after the lock screen appeared. I can get into the OS and use it for awhile, then it will restart and it all begins again. 2 factory resets so far and no dice. I am rooted on 10e but have a warranty device on the way which undoubtedly will be on a higher firmware and will likely miss out on the potential coming bootloader unlock. At this point I am probably going to sell on craigslist and get a 6p. The phone is great when it works and I love the size, the looks, and the screen, but the lag and these reboots are unacceptable.
Just a short update by me:
I gave it to the retailer, they said it would take about 10 Days.
I hope this stuff won't happen again or this was the last time i am buying a LG Product.
I think i would have been better off by sending it directly to LG but nevertheless, maybe giving it to the retailer will make my warranty stay longer
I will keep you updated, including firmware Version the phone has after sending it in and so on.
All of the sudden my phone today just froze leaving me with a black background and no animations, the phone is very hot if I try to use it on that moment. Even when I reboot the phone stays very very slow and says system it's no responding.
What can I do? Even when a Reboot it some times works normal then suddenly does it again.

Sounds like a heat problem in your case.
What happens if you pull out the battery, wait 10 minutes to let the phone get cold and than reboot?
Well, no luck on my end. I could only even get into recovery one out of every 50 times or so that I tried, and when I managed to I wasn't able to sideload any system software because it wouldn't initialize the driver (my computer recognized the phone just fine, except the ADB portion). Clearing the data did nothing either. Luckily I'm on Sprint and the phone's being recalled anyway, so I just walked in and they swapped it no questions asked. At least after flashing a TOT and clearing the data they shouldn't have an easy way to tell I was rooted or anything.

Thanks for replying, I completely restored phone today and was a success. No more black background.
same random rebooting issue here as well. and I just bought this phone brand new from a 3rd party :/
Update: I seem to have gotten past the problems after updating to 10n. Now running stock debloated 10n rom with no reboot issues (so far)
Update 2: Had 1 - 2 cycle bootloop on 10n

I don't see how you giving your phone to your retailer will extend your warranty. That makes absolutely no sense, since your warranty begins from your date of purchase.
My phone also ended up with the bootloop and having to exchange with a new unit. I'm on the TMO Variant H811.

Actually German Law is a little bit different.
Regular warranty is not what i meant in my post, i meant the "Gewährleistung" its an additional kind of warranty given out by the retailer.
There are some cases in which this "Gewährleistung", which usually lasts for about 2 Years is made longer. Mostly this happens when the retailer would have to send in a product for the third time, they basically give out a new one, which will be treated like a NEW device. So new Warranty, new "Gewährleistung".
I hope this somehow made sense
Today i got my phone back.
They repaired it.
Everything is like it was before, so i am pretty sure they didn't change it.
Firmware Version is 10d.
The Phone is working so far.
Will keep you updated if anything changes.

Phone won't boot

Hi All,
My phone will not boot. I have tried soft resets multiple times. It will not even boot after I selected the factory data reset by holding down the volume down and power button since it seems like that requires a full boot to reset. During boot it shows the LG logo and sometimes makes it to the AT&T logo but after that either black screens, back to the LG logo and powers off, or boot cycles and keeps showing the LG logo multiple times. I have taken out the SD card and tried all these steps with and without it. Took out the sim card and reseated it. The phone is stock and not rooted.
Let me know if you guys need more information or have any ideas.
Thank you all and I'm sure this is been solved before, but I'm at work and don't have time to research so thoroughly through all the threads/posts.
if it's not rooted and stock, i'd send it back to lg under warranty

I have already put in a ticket to LG before this post for their return shipping information and repair. I was just hoping by some miracle that someone had a fix besides a factory reset since it won't even boot to allow the factory reset.
Thank you
Ok, sorry for the lacking help! Good luck, hope someone else replies with a suggestion
This just happened to me too.
Shows the lg logo. Sometimes the att logo.
But, just doesnt boot up. All i see is a blank screen :/
From everything i read here on XDA it seems that many of the phones are faulty.
Symptoms are almost identical. Outta no reason reboots and dead phones. Many of them are stock not rooted.
I have still no answer from LG about mine. Hope to hear soon. Something is going on with these phones but what causes it.....that`s the question....
The same thing happened to my H-815 model. I went to bed listening to YouTube and woke up to a dead phone. The LED doesn't come on when charging. Just like you, when I turn it on all I see is the LG boot screen and then it shuts off. The phone repeats this twice and then doesn't turn on again.

HTC 10 boot loader infinite loop

Hey all you people with HTC 10. I just had to get a replacement 10. Out of nowhere my 10 just rebooted to the boot loader screen and the screen would show the boot loader for maybe a quarter of a second then it would turn off. It would repeat this cycle every 5 seconds. Would not respond to any combination of button presses.
My 10 was completely untouched.
I'm not sure what happened, but I'm starting this thread to maybe find some answers. Maybe it was a lemon or something else happened
anyone have any ideas?
I have the same problem...
I don't find issue...
I'm triing to change it with my buyer...

The phone just had a software update pushed to it so hopefully that fixed the bug. I really don't want to replace phones a third time since getting it just so takes a little bit for me but yeah fingers crossed.
Good luck getting a replacement phone, sometimes it can be hard to.

Thank you for your answer.
I also think that is a blind software update that cause the problem, but there is no solution to uninstall or find it...
My phone is now off, but if i try to on it(with charge or not, usb to cpu, volume down+power,etc), boot loop again.
Only the logo HTC is different when i use volume down+power, but no recovery mode available...

Anyone find an answer? Mine is doing the same,no recovery mode at all, just continues to reboot.
My Verizon HTC 10 tale of woe, after 3 weeks of awesomeness.
Got a new HTC 10 on August 3. I get an SD card, format it as internal storage and it worked fine until ...
Monday, August 22: I noticed that the soft buttons on either side of the fingerprint scanner weren't responding to touches. Decided to reboot the phone, thinking something was stuck in either the software or hardware, and a reboot usually fixes these types of things. However...
The phone went into a reboot loop: for several seconds it displayed a white background with a green HTC in the middle and the text "Powered by Android" at the bottom (called the 'white HTC screen' from now on), then went black for several seconds. Then the cycle repeats, and repeats, and repeats.
Did some looking around online and found a couple of potential useful button combinations: power/vol_down gets into recovery mode (except for me it displays a black background with a grayscale HTC logo in the middle (called the 'black HTC screen' from now on), followed by a black screen, displaying each for about a second or so (a faster cycle than the white HTC screen loop above.)
Also, the power/vol_down/vol_up combination gets into the bootloader menu, but not reliably. Sometimes the phone shows the bootloader menu (choices are Reboot/Reboot to bootloader/Download mode/Recovery mode/Powerdown)for a fraction of a second, then goes to the black screen and starts another reboot loop. It usually takes 2 to 4 attempts before I can stay in the bootloader menu.
Both the Recovery and Download menu options show the black HTC screen for several seconds, followed by the white HTC screen reboot loop. No useful options or other text at all. Reboot to bootloader reboots to the bootloader menu, reliably. Reboot goes directly to the white HTC screen reboot loop, and Powerdown powers down the phone.
If the phone is powered off (by the method above) and then plugged in to the charger, it displays a rectangle with a lighning bolt inside it (powered-off-and-charging display) for a few seconds, then the screen goes black and we go into the white HTC screen reboot loop.
Called Verizon support, explained the above to them, they send me a new phone which will arrive in 2 days. It does.
Wednesday, August 24: New phone arrives. I put my sim and SD cards in it, power it on, set it up, and start downloading apps. After I have a number of apps installed I take a break from that and format the SD card as internal storage. While this is going on (or maybe after it completed), the phone stops responding to the two soft buttons like the last phone did. This time, the phone rebooted itself after I fiddled with it for a little while, and it ended back up in the white HTC screen reboot loop. Argh!
Called Verizon support, fiddled around with the phone some more, and they said they would overnight me another replacement phone (waived overnight surcharge).
Thursday, August 25: I ship phones #1 and #2 back. Phone #3 did not arrive. I call Verizon, it turns out that the overnight order was never approved. It gets approved, I request Saturday delivery (it was too late to go out Thursday as the warehouse had closed).
Friday, August 26: I get a tracking number out of Verizon's system, check the Fedex tracking information and it's listed as Overnight, weekday delivery. I call Verizon again, they admit the screwup and send me another phone (#4) overnight, Saturday delivery (it's early in the day so there should be no problem getting the phone to Fedex in time for an overnight delivery.)
I check Verizon's system, get the new tracking number, check Fedex. Phone #4 is marked as second-day air, delivery on Tuesday. I call Verizon back, they can't change anything with Fedex after pickup. Looks like I'm getting 2 phones, one on Monday and the other on Tuesday. I get a bill credit for the time I am without a phone and all shipping charges are waived.
Monday, August 29: Phone #3 arrives. Put the SIM in but not the SD card, it's DOA with the white HTC reboot loop out of the box. I call Verizon, nothing useful. I get a new SIM card from the local Verizon store on the off chance that the problem is a bad SIM card. I have another phone coming tomorrow.
Wednesday, August 31: Phone #4 arrives, didn't have time to do anything with it until today. The phone comes up (with the new SIM), I start installing apps, and I then get a 'Firmware update available, download?' popup. I say yes, and then agree to the reboot when prompted. The display shows the 'unpacking' dialog, percent-complete goes up to 100%, then the phone reboots. White HTC screen reboot loop.
Call Verizon, this time they put me through to HTC support. They have me download something called 'HTC Sync Manager' (HSM from now on). While fiddling with HSM and the phone I somehow get it to boot successfully (but have never repeated this feat), it came up with the pre-firmware-upgrade version but the need-a-fingerprint-to-unlock configuration (and maybe other settings) has been lost. Looks like the phone isn't physically damaged at all, but something is messing up the bootloader. The HTC rep tries to get me to send the phone to HTC (with a 10-or-so day turnaround), I say no as Verizon is sending me phones with about 2-day delivery. I then retry the firmware download, get back in the white HTC screen reboot loop and never succeed in getting the phone to boot to Android again.
From my searching around on the Internet, it looks like HTC came out with an update on 8/15, maybe Verizon's OTA pushing of this update is causing the problem? No way to confirm, but it would explain why my phone was fine for 3 weeks, then kablooie across multiple phones.
The Verizon rep suggested taking the phone to the local Verizon store, maybe they can flash the phone with new firmware using tools not available to us mere mortals. Try it, no they can't do that.
Thursday, September 1: I ship phone #3 back. Order a Samsung S4 from Amazon so I'll have a working phone. 2-day delivery with Amazon Prime, and USPS delivers on Saturday. I need to take a break from spending my evenings on the phone with Verizon.
Saturday, September 3: The S4 arrives. It needs a different sized SIM card, but the local Verizon store has closed already. Call Verizon to try to see if they can do anything on the 'firmware update went bad' tack, maybe with a way to initiate a firmware download from the bootloader menu. No luck, but there's a new firmware update dated 08/31 that should fix the problem. He overnights me another phone (#5), estimated arrival is Wednesday due to Labor Day, and gives me a callback number so he can help me with downloading the firmware from the computer after getting the phone to its homescreen doing as little setup as possible.
Sunday, September 4: Go to a wedding. Make it to the Verizon store (in suit&tie) 1/2 hour before they close. They need the phone in order to activate the SIM. Drive home, get phone, drive back, get a working SIM. After 13 days, I have a working phone again.
TO BE CONTINUED....
The first installment wasn't "A New Hope", maybe this one is "HTC Strikes Back".
Wednesday, September 7: New phone (#5) arrives. Verizon tech support is busy tonight, don't get a call back from Verizon so I call them. Activate the HTC SIM, put it in the phone, and did a minimum config on the phone to get it to the homescreen. Connect the phone to the computer, put USB in software download mode, enable USB debugging. HTC Sync says 'No phone connected', driver installation popup complains about an unknown USB device but says several other HTC-ish USB devices are OK. Try disconnecting and reconnecting several times, no change. Sometimes get a 'virtual CDROM connected, run this installer or view files' popup, one time I copied its contents to the computer. During all this the Verizon rep forwarded me to HTC for assistance, but nobody answered. After a few minutes of dead air I got thrown into a satisfaction survey, I answered with 'would not recommend', 'unsatisfactory' and 'did not resolve my problem' responses. Dialtone.
Called Verizon back, had to wait again. During the wait I uninstalled HTC Sync Manager and HTC Driver Installer, reinstalled them (via the software on the virtual CD image) with the phone disconnected, then reconnect the phone. No 'unknown USB device' errors this time, but HTC Sync Manager still doesn't see the phone. Verizon rep suggested enabling USB Tethering. This produced a few more successful USB driver install popups but nothing helpful. Next suggestion is doing the OTA update (need to enable wifi so it doesn't eat my data allowance).
Download completes. Soft buttons on either side of the fingerprint scanner stop working (like before) even though touching the screen still works. I keep the Verizon rep updated as to the rapidly deteriorating state of the phone. He suggests a poweroff and poweron, I say it's gonna die if things go as they have but he says to do it anyways. I do, and the phone is in the reboot loop like all the others.
Verizon rep tries to call HTC tech support but they are closed. He'll call be back at 5:30 EDT to continue.
TO BE CONTINUED....
wow, its a real shame to have a device die on you but 5 is a catastrophe, really interesting writing though . it seems to me that the firmware update screws things up but then again many Verizon users have the phone with no similar problems whatsoever, would really like to be updated with any new information regarding the issue as it peaked my interest. sorry i cant help .

I keep the Verizon rep updated as to the rapidly deteriorating state of the phone. He suggests a poweroff and poweron, I say it's gonna die if things go as they have but he says to do it anyways. I do, and the phone is in the reboot loop like all the others.
Verizon rep tries to call HTC tech support but they are closed. He'll call be back at 5:30 EDT to continue.

I just had the same thing. Soft keys stopped working>Rebooted>Bootloop.
Very strange. Anyone else hear of this?
Are these issues hitting the "unlocked" version or the Verizon version? Could it be a CDMA issue?
I was debating picking up an HTC 10 due to having to return my Axon 7 because WiFi caused it to reboot constantly.
Wow just a few days ago the same exact happened to my 10. I happened to have an iphone 6s so after trying all day from the bootloader to reboot to recovery I decided to just sell the 10 in swappa boneyard. I bought it second hand from craigslist so didn't bother trying to contact htc directly assuming they wouldn't help since I didn't have an original purchase order. I put up a post here but never checked back to see if anyone replied with any solutions. Good luck. Seems like there's several people who experienced the same exact behavior. Such a shame.
The Firmware Menace
[ These are all stock Verizon HTC 10 phones (LTE/CDMA), not rooted, not unlocked or anything. All but the first were either dead-on-arrival or died attempting an over-the-air firmware update. ]
Thursday, September 8: Verizon actually calls me back this time, we try a number of things, none of which are different from what I've already tried and none of which work. They send me a new phone (#6).
Friday, September 9: I send phone #4 back.
Monday, September 12: Phone #6 arrives. I send phone #5 back. I leave phone #6 alone for the time being, I desperately need a break from spending my evenings on the phone with Verizon support.
Friday, November 18: I see that Verizon has a new version of the HTC firmware out and I decide to give phone #6 a try. Maybe the new firmware won't break the phone. I plug the phone into the charger (it's been powered off for 2 1/2 months), and it shows a battery charge level of 0%. I set it aside and do other things.
A while later I notice the occasional <bzzzt> sound. I identify the source as the phone, and see that it's in the reboot loop. (the phone vibrates momentarily when it displays the white HTC screen.) Another DOA phone.
Monday, November 28: I get around to calling Verizon and give them the 'firmware update went bad, replacement phone was DOA story, they immediately offer to replace the phone. Hopefully it'll have the November firmware pre-loaded. We'll see.
Thursday, December 1: Phone #7 arrives. DOA with the reboot loop. Called Verizon. They offered to send me another replacement phone (what's the point!), and then tried to get me to use an upgrade / get on device payments to get a different phone. NO WAY NO HOW! At this point I should get a no-cost exchange to a similarly-priced different model phone, not "throw away the $600-ish you spent on the HTC-10 and buy another phone".
I had to suggest contacting HTC support (they didn't think of it!), which they did. I explained what the phone was doing to the HTC rep, and he suggested I send my phone in for service. At this point what do I have to lose, they should send the phone back with the latest firmware. At worst, I'm right where I started (a non-working HTC 10). HTC is going to email me shipping instructions.
Midnight at the Cliffs of Insanity
Friday, December 2: Phone #6 goes back to Verizon, phone #7 goes to HTC to be repaired.
Monday, December 19: Phone #7 returns from HTC. Same problem. Phone charges normally at first, but goes into the boot loop immediately upon poweron.
There's no explanation of what they did, just a 'shipped from warehouse' receipt in the box. HTC's "track this return" page gives no details either.
Left a description of the problem (sent back a phone with a reboot loop problem, got back a phone with a reboot loop problem) on HTC's Facebook page.
Checked the serial number of the phone from HTC versus the serial number of the last phone Verizon sent me. They're different, it looks like they just sent me a new phone rather than reflashing the one I sent them.
Tuesday, December 20: Saw a response from HTC. In brief, try reloading the firmware with HTC Sync Manager or try contacting HTC Support.
Tried HTC Sync Manager. It never recognized the phone as being connected (in the bootloader menu, boot-to-download mode -> reboot loop, boot-to-recovery mode -> reboot loop, reboot -> reboot loop from both the bootloader menu and from poweron.) This is the same as previous attempts.
Contacted HTC Live Support, had to wait less than a minute (good). Explained the problem to them (including the 'sent a phone in for repair, it came back broken the same way' part). Blew past the 'did you try diagnosing the problem' phase in 3 1/2 minutes, and they want me to send the phone back to them. This time they'll create an escalation for the repair, hopefully this'll provide more visibility into what is going on and avoid another "didn't do anything to repair, shipped a different, just-as-broken phone". They also said that they would manually test any phone before sending it to me to make sure it has the latest Verizon firmware and boots successfully into Android. The proof will be in the booting.
Wednesday, December 21: Phone #7 goes back to HTC.
Another One Bites The Dust
Friday, January 6:
Phone #7 comes back from HTC (same serial number). Boots up (no sim, no SDcard) fine. Insert sim, reboot, still OK. Switch service to the phone, it works. Latest Verizon firmware is 1.85.605.9, the phone is at 1.85.605.8. Load some apps, start using it. Put in an SDcard, format as internal storage, everything is good so far. Everything is working as expected.
Saturday, January 7:
The phone works great for most of the day. Late in the day I get a notification about a firmware update, which I defer. A couple hours later I notice that the soft buttons on either side of the home button/fingerprint sensor had stopped working. (just like the original problem with phone #1). Found a way to force the lights to be on when the phone is on (someone said that this fixes the 'soft buttons don't work' problem, but I think it was just a 'soft buttons don't light up when you want them to be lit' problem. Found the setting in Settings, buttons light up but are still unresponsive.
Reset the phone (DIDN'T install the firmware update), back in the infamous reboot loo, same symptoms as before. Tried removing the SD card and SIM card (A Reddit comment thread said this worked for some people), no help.
same problem here.. looks like there is not any solution.. right?

I am experiencing the same problem since today. The phone has the latest update installed. (not rooted, bootloader locked)
Its so disappointing ! I'm in India but I bought this phone from middle-east on December 2016 and I have to sent it back there for warranty claim which will not happen very soon.
Have anyone found a solution for this problem ??
My only solution when this happened to me was do the Boot Recovery reboot and recover/reset phone. Press Volume-Down and Power button together for at least 30 sec. You have to wait. A black screen with gray HTC will show up. Only let go once you see this screen (not before). Select boot to bootloader, then boot to recovery. Then do factory reset.
Its happening to unlocked versions also, i bought mine from Sydney unlocked and it just happened to me. IM freaking out i dont know what to do!!
Someone please help if they have a solution
GRETEL GT6000 Infinite boot
Hi everyone,
I recently bought a GRETEL GT6000 for it's awesome battery,
sadely this phone is hard to root.
I try many & many solutions but no one root the phone and now my phone is in infinite boot with message "Orange state you're device has been unlocked and can't be trusted Your device will boot in 5 seconds"
I can't connect to adb or fastboot, I can't boot in recovery (volume up and power), in fact I can't do anything.
I try to pull of the battery but it didn't change nothing.
The last thing I was doing before this, is to flash a custom recovery.img (made with both official rom and a TWRP rom).
I'm hopeless & I'll be glad if somenone have an idea to share it here.

LG G4-NOTHING works!

Hi everybody, first I want to thank all devs for their work! It's greatly appreciated, Thank you!
Alrighty then I have the USCC LG G4 running or was running US99122a. Three days ago it's started to restart when ever it wanted to no matter what the battery level was at, plugged in or not just up and restart, then very shortly after it would restart with in the very first minute of being fully booted. Then shortly after that it just went into a bootloop and is now stuck on the LG screen. I have tried everything that I can find on the internet with absolutely no success of any sort. Ive went in to reset mode using voldown+power and when say yes to final warning it just stays on that screen like its frozen then eventually reboots back to being stuck on LG screen. LGUP does not work, it doesnt find it's model number. it knows what com and us99122a but unknown for model. Lg flashtool stops at 9% during s/w upgrade and either says lost connection with server OR needs/ask administrator permission (something like that but meaning the same thing) I've read that when it does don't disconnect don't do anything and after 15 to hour later presto good to go but no, no presto. I decided to ask you guys after leaving it like that for little more then 24 hours now. I need serious help as I cant afford another phone and my g4 was everything. Internet, tv, movies, work, research literally everything through miracast PLEASE HELP and thank you!
Only fix for that is a board replacement or warranty. Google LG G4 bootloop it's a common and known issue.

install LG bridge and try this, connect phone in download mode and let LG bridge to recognize your phone, then click on update error recovery blue text in down right corner...
other thing you can try is this dll https://drive.google.com/file/d/0ByAmkJVge8jybmN5UWo0R3MwWjA/view?usp=sharing
place it in right folder, reboot pc and try with LG UP

little update for ya after trying LG UP and another LG software install pc program and 2 other android firmware versions all it would do is freeze at 9% then nothing no matter what i tried OTHER than finally getting hard bricked. (pc said when connected corrupted device not recognizing it) So I am now a firm believer in and advise to others with this problem if you're able to get it replaced through LG do it cause that is the only fix. Even tho I could of had replaced I didnt do that, instead I grabbed my 30-30 deer hunting rifle and blasted one lonely hole!!, Yes a hole and I tell you what the screen on the G4 is superb ! besides immediately around the bullet hole it didnt even spiderweb. id say 65-70% of the screen was still crack free!! no joke!

Need Help, Bootloop issue...

Hello,
New to the forum, at least posting have been lurking and reading for years, but this will be my first post.
Mi 10T Pro, stuck in bootloop. I have been trying to get it going again and have been having no luck, so I decided it is time to turn to the pros for some help.
Symptoms:
Bootloops 1 or 2 times to the MIUI logo, then boots to the recovery menu
Not possible to turn of completely, bootloops until battery drains completely
Able to get to the fastboot menu
What I have tried:
I had a suspicion that it was a problem with the power button, so i replaced the ribbon but no improvement (Unless new one is bad also?)
Replaced Battery, no improvements
Tried all the button press combinations to try and do hard reboot and so on
About Device:
Software version: Unknown as the phone broke a long time ago, got a replacement and the phone has been sitting in the drawer...
Phone was never rooted or unlocked in any other way
The phone is open and I could unplug battery or try a new ribbon for the power button (I have a new one on hand)
What I would like to achieve:
Save the data that is on the phone.... This is the main thing I would like to do as there is precious pictures of my young kids and so on....
Get the phone working and use it as an emergency device
Options I think are still available in order of how I would like to attempt them:
Do a software recovery, by installing a stock rom, example: (
)
I don't know what version of rom to download as I don't know what version the phone was on
I don't know if this will work since the bootloader has never been unlocked
Anything else possible before next step?
Reset through the reset menu. and cry over all the lost data (
All suggestions are welcome.
Thank you!
this phone is notorious for needing to be reballed after a few years of use. its a trash phone. join any mi 10T groups in facebook and youll see countless users who had to pay specialist technicians to reball their CPU and Memory chips and even then, they still fail after a few weeks/months.
Thank you for your answer ongkal. So you don't think its worth to try to overwrite the loader? I don't want to have to reball if its a software issue, but will if it comes down to it.
Mainly just want to get the files out, went back to samsung after first phone with xiaomi...
I was just looking at the reball videos on youtube and most of the phones are completely dead, mine still turns on but straight into bootloop. Besides they say it might be due to gaming, which that phone has not seen
