Hi guys,

How I bricked my phone:

I tried to flash the stock recovery because I wasn't able to flash any firmware upgrade using OxygenOS 2.2.3 and TWRP-3-0-2.

To do so I enabled USB-debugging and checked unlock OEM in the developer options and restarted the phone into fastboot mode.

Then I tried to flash the stock recovery:

~/oneplus » sudo fastboot flash recovery recovery.img
target reported max download size of 1073741824 bytes
sending 'recovery' (14758 KB)...
OKAY [ 0.464s]
writing 'recovery'...
FAILED (remote:	Device not unlocked cannot flash or erase)
finished. total time: 0.465s

The bootloader should have been unlocked already at this point but I tried to unlock it anyway:

~/oneplus » sudo fastboot oem unlock
...
OKAY [ 0.011s]
finished. total time: 0.011s

The phone rebooted and was stuck in the oneplus logo screen.

trying to boot into recovery mode (turn the phone off and restart pressing volume down) as well as 'fastboot reboot' and 'fastboot continue' produced the same results.

Using fastboot reboot bootloader brings the device back into fastboot mode.

'fastboot oem device-info' reveals:

(bootloader)	Device tampered: false

OKAY [ 0.006s]

I also tried to erase cache and data but apparently I'm not allowed to touch the partitions in any way.

It seems to me that the key of resolving this problem is to somehow unlock the bootloader. Can you think of any way to do this?

Is it possible to flash anything without successfully unlocking the bootloader?

Any other suggestions? :)

Kind Regards

Thank you. I thought I could avoid that but it works pretty flawless. :good:
[OnePlus X Q&A, Help & Troubleshooting] Aamod Joshi:
You should've used

fastboot oem unlock

For unlocking the bootloader. The reason why your phone got bricked was because the bootloader wasn't unlocked. In order to flash zip files or flash recoveries (or do anything that is related to modifying the system) you need the bootloader to be unlocked
[Samsung Galaxy S7 Questions and Answers] alexx3333:
Hi,

I think I have bricked my S7.

Yesterday I installed Superman Rom and everything was working fine until this afternoon.

I played a bit around and somehow my S7 got stuck and it seemed like i messed something up. I was in some kind of bootloop so i flashed everything new -Bootlaoder, Modem and Superman Rom.

Now I have a black screen and the LED is light up in blue.

I can't do anything. Tried to restart with Home Vol- and Power key but it doesn't work.

If I connect it to the Computer it won't be recognized.

Strange thing is, if I press the Power Key the computer recognizes Exynos8890 in the device manager, but only if I keep pressing the power key.

As soon as I release the power key the computer recognizes nothing...

Does anyone have an idea?
[Samsung Galaxy S7 Questions and Answers] *Detection*:
Try holding Volume Down & Home & Power until the phone reboots twice, keep the buttons pressed for 2 full reboots, and hopefully the 2nd one will get you back into download mode
[Samsung Galaxy S7 Questions and Answers] alexx3333:
Thank you for your help!

I tried that but it doesn't work.

It's strange because I can do what I want and nothing happens.

Black screen and blue light. It doens't even turn off or reboot...

Only thing what happens is that exynos8890 appears in the device manager as long as I keep pressing the power button. :confused:

Because you are able to get into recovery and download. I'm not able to do that :(

How long are you holding the button combination for?

I tried for several minutes, but the phone doesn't do anything.
[Samsung Galaxy S7 Questions and Answers] *Detection*:
I can only think you'll need to wait until the battery runs out, the phone shuts off, then when you charge it again, try the download mode button combo when you power it back on
[Samsung Galaxy S7 Questions and Answers] alexx3333:
Ok thank you.

I thought the same.

Unfortunately the battery was at 90% so I think it will take a few days/weeks until it dies...
[Samsung Galaxy S7 Questions and Answers] *Detection*:
Connect the white Micro > Normal USB adapter that came with the phone to the MicroUSB port, and connect a power hungry USB device to it, I just tried with a USB desk fan and the phone powered it on spinning

That will drain the battery quickly
[Samsung Galaxy S7 Questions and Answers] alexx3333:
Great idea but it doesn't seem to work.

Looks like I have no power in the USB connection. :(

Seems like the phone is totaly frozen.

Ok so how it looks at the moment, my only choiches are wait several days until the battery dies (don't know how long this will take) or sending it to Samsung for a repair. :(

Thank you for your help!
[Samsung Galaxy S7 Questions and Answers] *Detection*:
Good luck, if I think of anything else I'll reply here, hope you get it sorted

EDIT - Did you try holding the power button while you had the USB device connected, to see if it provides USB power then?
[Samsung Galaxy S7 Questions and Answers] stoanhart:
Wow, the exact same thing literally happened to me yesterday.

I wasn't doing anything to the phone - it's completely stock and unrooted, and I wasn't messing with anything. At the time it happened, I scrolling through the task switcher when all of the screenshots of running apps suddenly became white squares. I tried pressing the home button but it didn't respond (though I could still scroll fluidly through the white squares). A few seconds later the screen went black and that was it. Dead dead dead. Totally bricked. The only response I can get is "Exynos8890" in the Device Manager when holding the power button, just like you.

This really sucks because I paid full cash and imported an international version, so I have no warranty. I'm off to the Samsung store to plead with them about honoring the warranty anyway, maybe if I offer some cash on top.

I suspect the storage chip failed. Yesterday before it died, I was downloading all of my images off of the SD card to organize them, and I noticed that about 5% of them failed to copy due to an unknown I/O error. Of course I assumed this was a corrupt SD card, not internal storage. I did manage to pull them all off (though some were damaged) through a combination of adb shell, dd, and adb pull. During the process the phone hard-locked a few times, but each time I was able to reboot via the VolDown+Power combo.

When the phone finally died for good, it was several hours after I had finished copying the photos and since hte last reboot. It had been working perfectly since then - I was browsing reddit, watching netflix, etc. However, given that I got the white squares in the task switcher right before it kicked the bucket, I think the internal storage was actually to blame, not the SD card. The white squares indicates that it was trying to fetch the screenshots off the disk and failing.

It's very odd that I cannot find any other instance of this kind of failure on the internet except this one thread, which happened on the exact same day that my phone died. Very strange.
[Samsung Galaxy S7 Questions and Answers] alexx3333:
Yes I have tried that but no power at all...

That sounds exactly like my Problem.

A faulty storage chip would also explain my Problems before the phone died for good.

The day my phone died I had some Problems. The phone was frozen from time to time until it got into the bootloop, but I thought I messed something up in the Rom because I did a lot of testing and the Combo also did work.

After reflashing the Rom everything seemed to be fine first until it died for good.

Yes it's strange, I also didn't find anything similar on the Internet.

[Samsung Galaxy S7 Questions and Answers] stoanhart:
I managed to get Samsung Canada to refer me to a local service center. I drove 1.5 hours to go there today, the dude plugs it into a charger, and the damn thing just lights up like nothing ever happened. Now it's working fine, but I swear this thing was fully bricked before. The battery still had 73% charge when it came back alive...

I'm happy it's working now, but I'm worried it's just going to crap out again at any time.
[Samsung Galaxy S7 Questions and Answers] stoanhart:
Update: after the phone revived itself, it worked pretty well for a week. It locked up a few times, but I was able to reboot each time.

But, after a week, it hard-froze again. This time, it happened to be on charge while it froze so the green LED was on. It's been completely unresponsive for 2.5 weeks now, off charger, with the green LED on. I keep waiting for the LED to drain the battery, but it's taking forever. I'm losing hope that it will recover this time. I guess I'll re-start the process of getting in touch with Samsung, or alternatively, look for a replacement motherboard on eBay.

Does anyone know if the G930F motherboard fits into the G930FD body? I don't actually care about dual sim, but I'm concerned the SIM tray/slot won't work with the G930F motherboard.
[Samsung Galaxy S7 Questions and Answers] alexx3333:
Update:

so in the meantime the battery of my s7 died but that didn't change anything. I wasn't able to charge it after that so now it was completely dead.

So I contacted Sasmsung.

They replaced the motherboard and the USB connector on warranty.

Seems like it really was a hardware issue...
[Samsung Galaxy S7 Questions and Answers] cyadron:
Hi,

Do you need Proof of Purchase for the warranty?

Thanks.
[Samsung Galaxy S7 Questions and Answers] 012512:
Mine froze not too long ago. Probably 2 weeks ago. My phone froze while I was playing and it vibrated endlessly until I manually rebooted the phone. I hope this will not be a hardware issue though. I also updated the current custom kernel imto latest and see if that happen once again.
[Samsung Galaxy S7 Questions and Answers] alexx3333:
I didn't need one.

But on the time I gave it to Samsung every S7 was on warranty...
[Samsung Galaxy S7 Questions and Answers] fireclaw316:
You might as well give up now. I posted about the same kind of issue, but all I did was install a custom recovery and then root my S7. I never installed a custom ROM.

I'd suggest you read my post, as I go into quite a bit of detail, but the main point is that, even after using Odin to flash EVERYTHING back to stock, I can't even get into Download Mode anymore.
[Samsung Galaxy S7 Questions and Answers] fireclaw316:
OK, I have a theory about what exactly is causing the phone to break:

We all know that we can't boot into Android for some reason, and some are suggesting that the NAND flash is f***ed, and I have to say that I fully agree with that. When I first started to attempt to diagnose my phone's bootlooping, I wiped it, doing a NANDroid backup to an external USB drive with that OTG connector that Samsung includes with the S7. About a week later, I tried copying some files to the USB drive from my computer, but Windows kept saying that the drive was write-protected, which is literally impossible. I tried formatting the drive, repartitioning it, and doing everything else under the sun to fix it, but the drive is just broken, and I didn't know how. I've had it for a little over a year, and I'd only been copying data to it a couple times a month, because I primarily used it to store my, uh... totally legally-obtained collection of audiobooks.

So, needless to say, Galaxy S7s that are experiencing this inability to boot potentially have the ability to damage external USB drives, and I would have it a guess that it could damage anything else with NAND flash that you connect through OTG(including phones). I had a micro SD card in my phone the entire time I had it(AKA 2 months), and it's still in fully-working order, so it seems that the SD card slot isn't affected. Maybe that's because I didn't do a whole lot of writing to it, maybe it's just connected differently than OTG, maybe if I'd tried to write my NANDroid backup to the SD card, it would have died as well. I don't know. I can't exactly find out.

Hi,

A camera is a very important factor for me when buying a phone,

I bought my Redmi Note 3 after reading some underwhelming reviews about the camera, thinking "oh well, how bad can the rear camera be?" - well, the camera is really under performing, very soft images, noticeable noise in almost every scenario, very disappointing.

My question is that,

Is it really a hardware issue, or just poor camera algorithms coding?

if the former, I will just look for another phone and sell mine,

otherwise, I will (try to) wait patiently until the appropriate software update will come

Thanks

[Xiaomi Redmi Note 3 Questions & Answers] otyg:
I think it takes good pictures but I found that any kind of motion will blur the picture (even just walking and snapping a pic), so motion sucks, try taking a picture of a moving dog it will just be a blur, low light also sucks, but if you take still pictures under good lighting pictures look great, I think there is a soft spot for this camera it's just hard to find, also lowering the resolution to 12MP will take 16:9 widescreen photos rather then 4:3 photos in 16MP mode
[Xiaomi Redmi Note 3 Questions & Answers] goofball2k:
Part of the problem is it never wants to increase the shutter speed properly in order to keep iso low. It tends to take most pictures at 1/25th or so, which is great for static but not for moving objects where you need a faster shutter speed to freeze motion.
[Xiaomi Redmi Note 3 Questions & Answers] vampire585:
low light shots are average.

daytime shots are great.

did you tweak the default settings?

which ROM are you on?....try to be on latest MM dev or china rom

also try using open camera.

i am from india....i have OPO(Rooted+MultiRom) from jan 2014...no problem so far..

last monday i got 3 Jio sim card.

for me (OPO) , my bro (Brand New Redmi 3s prime) ,my friend(YU Yureka)

they have given 2 sim without Barcode (bcz...both of our generated Barcode was expired..)

we inserted sim in primary slot and

after One hour all three sim activated and getting signal nicely.

but now..(all three phone have same problem)

when we have tried to insert other operator sim in this particular slot , it shows "No Service" and getting error like "there is a error in searching network"

i tried my best to resolve issue myself but no luck.

i tried flashing different Roms(LP/MM/Naugat), Different Modem and tried IMEI changer app too but no luck

i contacted local Jio center but they says "issue is in your end...claim on your phone's company"

i called Jio customer care they said "after 90 days your phone's slot will be automatically unlocked"

i googled alot on net but many blog admin says it is rumors & and fake but we are suffering from such a serious issue in real...and if somebody want to help i can upload video of this issue.

so My question is.... Is Jio is blocking phone from using other sim??

if yes..then why and how to overcome this issue??

can anybody make patch/mod or xposed module to get over this issue??

any Help will be appreciated.. _/\_

*sorry for my bad English*

Update: Nov/26/2016

Solution..(what i did..)

-flash Resurrection Remix Rom 5.7.4 Last build

(check if ur current Rom have "EURO BAND" Option)

-After boot Dial *#*#4636#*#*

>Phone information >click on top three dot menu > select radio band > EURO BAND

-Reboot your phone
[ONE Q&A, Help & Troubleshooting] shubhaemk:
No such thing ever reported by anyone, my friend is using in Yureka with no problem. Your phone cannot be locked with just a SIM though. Flash stock and then type *#*#4636#*#* in your phone and try selecting some different radio bands, UK band works fine as reported by some users.

Try switching slots in your friends phone and the bands ofcourse. ;)

May be your mobile phone got changed its IMEI number with lyf handset by mistake or may have done it ( i dont know that).

Just try to enter your IMEI again in your device which need root for the procedure. There are plenty of tutorials and videos available over internet. So do it on your own risk and may be it will work.
