Hi,
I recently rooted my nexus 7 and flashed TWRP recovery. One day I got into the recovery and started playing with it. By mistake, I erased my OS. I then came to know to know that i could fix it by flashing a custom ROM. I installed a custom rom successfully. I then wanted to go to stock. While flashing the stock OS, it got stuck in bootloop. It was too late so I thought to flash it the next day. On the next day, when i tried to switch it on, it did not start. I kept it overnight for charging but it was of no use. Then i went to the Asus service center, and i came to know that there was a motherboard problem. I did a little research on google and came to know that to earn money they told it was a motherboard problem. Many people had fixed it by unplugging the battery and replugging it back. I tried that, but it was of no use. I did not play with the bootloader. But now I think that it could be hard bricked.But I am not sure. So any idea whether it is hard bricked or really is the motherboard spoiled or what??
Thanks in advance

Hi folks.
So after a sleepless night and a lot of guessing and clicking around with no luck, I finally decided to ask for help.
The story:
Yesterday, I decided to open up my lovely N4 to perform the thermal pad mod (that can be found on these forums), as it was going really hot around the CPU at time and it seemed like a good solution.
Now, I'm no stranger to disassembling microelectronics without breaking them (few weeks ago, I successfully resoldered a broken power button in my old T989 that I've been using before N4).
What couldn't let me sleep at night:
And here is where the problem emerged. After re-assembling my sweet little phone (yes, i did it perfectly right), I tried to boot up and all i could see was an endless and really annoying bootloop, but as the device booted up, I did not worry much. While doing some research, I read that there's people experiencing bootloops with 4.3, so I thought that after disconnecting the battery, it just might've had happened on its own (I was using stock 4.3 with faux kernel before the nightmare started)
At this point, I booted into recovery and tried to flash the rom over, but unfortunately nothing positive happened. Then I tried factory reset and flashing different roms, also with no luck. This is when things started to get really frustrating, as no matter what I flashed, the bootloop was (and is) still there. But then I tries to restore a backup that I did right after getting my N4, back in November, and it WORKED. Why do i still have a problem then? Because it was 4.1 and OTA was giving me error every time I wanted to flash the update, so I kept flashing till i get some results. And then one of the N4 toolkits wiped my entire internal memory and I ended up with only being able to use sideload. Then I tried ALL of the N4 toolkits that can be found in here, to wipe everything and bring my phone back to everything stock, but the bootloader is locked so it cant do it, and it cant unlock it because I cant boot into the system.
Conclusion:
The phone works fine, and it proved it. But no matter what I try to flash (other than the old backup), the persistent bootloop is still there smiling at me like an a****le.
Any ideas?
Hello all,
This is yet another bootloop story, although I haven't found anything quite like it yet, hence the idea to post it here for reference and in case some of you have interesting ideas to explore...
This is gonna be a bit long, but TL;DR: After my phone got "spontaneously" stuck into a bootloop, I find that only the stock 4.2.2 rom works, and no other.
So, tuesday I get back home with an empty battery and a Nexus 4 (running latest OTA) that has switched itself of after a day of somehow intense usage. No worries, I plug the AC adapter, let it charge for a bit and switch it back on. Booting seems a bit long, but I have to take care of a few home chores so I let it do its thing before coming back to it a few hours later. Only to find it still displaying the animated nexus logo. After a few switch off/switch on cycles, I understand its pretty stuck and I need to be more radical about it. So I enter the bootloader menu, and OEM unlock the phone (I had never needed to do that) hoping the full wipe associated with that will clear things up.
Well, it didn't. So I guess I'll need to flash a stock rom, and so I do. Since 4.4 is available on Google's stock roms page I try that, the animated logo changes but the end result is the same. So I try again with the latest JB (4.3) and still the same result. I get more than a bit frustrated but it's late and I need some sleep.
The next day, I call Google's warranty desk in France. They tell me that since the phone fell a few month ago, they cannot take it under the warranty program, and so I have to ask LG. Knowing there's no reasoning that will get me past the clerk that answered the phone I hang up after saying I'll get back to them via snail mail. Which I'll probably do soon, because I'm very disappointed with the way that warranty desk works.
Once at work, everytime I have a few spare minutes, I try to reflash with a new tool just in case it does more than automate what I did manually (nexus root toolkit being the one I tried most). It doesn't change a thing and my phone is still a nice animated paperweight.
I don't know why I ended up trying that, but I finally tried flashing the original 4.2.2 rom, and lo and behold, my phone finally got to the SIM code screen ! Everything worked nice after that, so once back at home, I go for the offered OTA upgrade to 4.3. Well, guess what, back to paperweight. Before reflashing 4.2.2, I took the time to flash CWM and activate adb by modifying /system/build.prop in the 4.3 image. This showed a recurrent problem with "system_server" segfaulting at launch (and it might have been caused by hal_sensors_get_list not returning anything, I have no clue). Trying the same on 4.4 yielded the same result.
Back to 4.2.2 and everything works fine, but I get nagged by the OTA notification, and more than that I'm wondering if there's any hope I might understand and fix the problem with my phone.
So, ladies and gentlemen, any clue that would help me is very welcome !
I plan to try a CM rom this week-end to see if it has the same problems as the stock one, but I have little confidence it doesn't. My guess is I have a hardware problem that's non-critical except it triggers a bug in 4.3+...
Thanks for reading !

Same case, mi phone is totally stock and stuck on logo
KRT16S: no luck
I only had the time to try KRT16S this week-end, and this latest update doesn't change a thing. Same symptoms. So I guess I'm stuck on JB 4.2 for the coming week...
Hi,
I have a big problem with LG G2 from At&t. I've bought on swappa.com for using in Trinidad. When I bought it, It was running a 4.22 stock and rooted and unlocked. Everything worked well except quick remote.
After some time new (last week) the phone started to freeze and reboot about 5 times a day. Sometimes when it was rebooting it would cycle on/off a few times before it would boot successfully.
I thought it was just a software error so I had done a factory reset and install the stock rooted 4.4.2 rom but still had the same problem. I even tried cloudystock 2.2 and had the same problem all with no additional apps installed.
Is there any way to troubleshoot the error? Is this a software or hardware problem?
It there anyway from this mess?
Thanks for every suggestion.
Same issue
Hello,
I am having this exact same issue. Did you ever find a fix for this? I have been searching for hours. I have tried numerous things, flashing back to stock with lg flash tool, installing different roms, it happens on all roms.
Thanks
For me it was a bad motherboard. I ended up buying a tmobile board and replaced it. Everything worked fine after. Try a battery change first though. That might solve it as my battery was bad and maybe that made the motherboard go bad as well. I bought a motherboard off ebay so that's where I sourced it if you want to go down that route.
Thank you very much for your reply. I was actually wondering if it might be the battery. I will try that first. Again thank you for the reply.
Hi.
I've had numerous nexus phones and generally dont have many issues however randomly today my phone entered a bootloop. I decided to completely flash stock firmware (how i normally solve issues but no matter what I do it just continues to bootloop.
I can get into Fastboot but thats it.
Any ideas or experience of this anyone?
Thanks in advance
Gave up in the end, couldn't fix it.
google replacing under warranty
Just had to do the same thing last week. Using Uber Partner app and when I accepted a "call" phone crashed and began bootlooping. Tried fastbooting stock image but ended with "Phone is Corrupt" message and continuous boot loop before replacing under warranty. I was running August update Benzo ROM. Never experienced anything like this before and I've been flashing for 5 years now. Sorry about your device, the new one in the mail will make it all better best phone ever!
Oh god... I think my device is doing the same thing.... I've tried flashing stock through fastboot twice now. Still saying my device is corrupt. Even tried a different cable, and redownloading the firmware.

This happened to me too the same day out of nowhere. Google sent me a refurb. Battery in this replacement seems much better. I couldn't even get into the recovery.

Hey everyone,
I have been looking around online for several days now, but haven't been able to find a description of the problem I have with my n910f nor a solution.
When I got the phone it was stuck in bootloops and so I though it was soft bricked.
After I installed the custom rom and the latest version of TWRP via Odin, I thought that the problem was fixed, because the phone booted and I was able to start the configuration of Android (where it asks you for language, time zone etc.)
However, the phone turned itself off during this process. So I wiped everything and tried again, the same thing happened.
I then flashed it with Lineage, but it would turn itself off even before the logo appeared.
Then I flashed it with Ressurrection ROM, but again, the phone turns itself off during booting.
I can access download and recovery mode without any problems, I can flash roms and Odin works like a charm. I also used 2 different batteries.
Does anyone has an idea what I could try? Could it be the version of TWRP I am using (3.0.2.0)? Or is it a hardware issue?
Thank you!!
Hi, I have this exact same issue with my N910T and so far haven't found a solution to this. I really love my Note 4 so I'd like to know if this issue can be solved or not. I event went to a supposed repair shop and they couldn't figure out the problem, guess they weren't that good.
Sorry to hear this.
I have found issues that seemed similar, but not quite the same, and people hinted that it could be a worn out motherboard that is causing this top happen. But before I open up the phone (at the potential risk of breaking at least the screen) I would try everything else.
Or is there a way to test whether the motherboard is defective?
Its the plague of overheated, worn out emmc memories, sadly. Once it happen,the only way is a new/used motherboard,prefferably C model.
eMMC failure, snapdragon models are susceptible to this.

I suggest flashing stock rom with Odin after wiping your whole device in TWRP. I've had the same thing about 2 months ago.
Hey,
thank you for your responses. Yes, I read a lot about it being a motherboard problem.
I got it to work now thanks to this post: https://forum.xda-developers.com/note-4/general/downgrade-official-mm-to-kitkat-t3383885
First nothing happened, but after I flashed Modem and the original Bootloader again (after installing the rom) the phone turned on and I was able to use it for a while (20mins maybe). Then suddenly it turned itself off and stayed on the "Samsung Galaxy" screen for a long time.
Apparently a lot of people are using Wakelock and it seems to be working for some of them, but that seems to defy the point somehow.

Which Stock Rom did you use exactly? Is your phone working fine?
