Hey there, been wondering about the same thing...

For me, the phone itself seems to be working with both boards, but no charging with either of them. So I'm guessing it's the motherboard diode that's burned. Still I'm a little reluctant to just cut it, does anyone know whether the protection by just one diode on the charging board (if it's not burned, or I replace it with the new board even though it doesn't seem to be the right model) is "safe enough"? Did anybody face issues with both diodes removed? (I kind of fear my battery blowing up randomly :D)

And another thing I noticed: my PC doesn't recognise my phone when connected. Nobody said anything about this here - is this "normal" if the diodes are burnt, or do I maybe face an even bigger issue? Does anyone have the charging problem but the phone is recognised on their computer?

[EDIT]

So I checked the voltage on all of the zener diodes (both USB boards and motherboard) when connected and the results are the following:

both USB boards: 0.06 V

motherboard: 0.05 V for both USB boards

I checked the multimeter on a battery and it's working fine. My knowledge concerning physics isn't that good that I know whether the voltage on the USB diode would be 0 (or almost 0) V even if the motherboard diode was the only one burned. Otherwise that would mean that even the newly ordered USB board is faulty... :/ I still don't really like the thought of cutting diodes, but I guess that's what I'll try next.

[EDIT 2]

Works like a charm... I cut the motherboard diode, put the original charging board back in (didn't remove that diode), plugged it in and it's charging like nothing ever happened. :D THANKS FOR SAVING MY PHONE!

Also there's a voltage of about 5 V now when I check the spots where the diode used to be. In case anyone needs it, there's a picture of the cut diode attached. (Well... As soon as I figure out how ._. Or does that only work after the first 10 posts?)
[Xiaomi Redmi Note 3 Guides, News, & Discussion] Apcoolboy:
You are lucky that your charging board zener didn't burn. Because if you replace it then it might cause you some network issues. Anyway, one thing I want to say that I also removed mother board diode and then using new PCB with diode on it. And also qc 2 charger with limiting input to 2100mA max (agni kernel). 10 days no problem yet. Fast charge working fine and PCB survived (also mother board lol). Before thet I had Radeon kernel installed with 2500mA. And that caused burning up 2 PCB diodes (including my original PCB) and mother board diode lately. That not limiting input current was culprit.

In nutshell, you can survive well with qc chargers with only PCB diode but need to limit input current.

thanks it's working
[Xiaomi Redmi Note 3 Guides, News, & Discussion] SoulSlayer69:
As living without overvolt protection isn't the best, and the next one to die after them is the regulator, I manage to change those 2 zener diodes: their SMD-code is BB for the one onto the motherboard and 8F for the one onto the USB charging flex. They are obviously really cheap, 0.30 cent each here in Europe, but you need good soldering skills or a professional repair.

The 8F is a 3 pin zener, just cut away the pin2 and solder anode and cathode onto the 2 (they are 2 twins in a square) board pins, respecting polarity (easy to check from micro USB).

Hope it will be useful for someone else :)
[Xiaomi Redmi Note 3 Guides, News, & Discussion] philto:
thanks at all, i am not a specialist, but a want to try to change the 8F, for the moment my phone is ok without him...

Hello Sir, I cut the zener before, what's the worst thing that could happen if there's no overvolt protection ? will it explode ? :eek:
[Xiaomi Redmi Note 3 Guides, News, & Discussion] SoulSlayer69:
You can burn the motherboard, burn the battery, it could explode. No one knows because it's not something it should work in that way, without the zener I mean. And keep in account that Snapdragon 650 is a very fast CPU, but it's always hot.
[Xiaomi Redmi Note 3 Guides, News, & Discussion] Dan101:
Brilliant, this worked for me too, very valuable advice, I used a sharp knife to break the diode 'glass' carefully, best wishes, Dan
[Xiaomi Redmi Note 3 Guides, News, & Discussion] panuganties:
i used a needle to cut zener (i have problem with charging board)

but

if i connect charger, battery was charging for 5mins. after 5 mins connected and disconnected contineously,

if i connect to laptop, not charging but connected.
[Xiaomi Redmi Note 3 Guides, News, & Discussion] Apcoolboy:
If connect disconnect constantly then either your cable/adapter has been damaged. Or if cable is fine then it is sign of your charging board will not working soon. So just change ur charging board.

hi,

tahk you for the post....my kenzo rebirth after 10 months ;)

one question, my zener diode was bc marked ...

my kenzo geta damage after use a powerbank aukey, but in a stranger way....phone and powerbank was full discharged and a friend of mine linked both with no reason...after that icouldn't recharge my phone until yesterday...
[Xiaomi Redmi Note 3 Guides, News, & Discussion] Aspide100:
maybe this one philips BZX399-C5V6

what you think?
[Xiaomi Redmi Note 3 Guides, News, & Discussion] jorgealheiro:
any advice how to cut the diode? you only need to remove the black cape above or really need to cut till you see the board?
[Xiaomi Redmi Note 3 Guides, News, & Discussion] piiidtt:
I also encountered one burnt zener diode on the motherboard. When I used a multi-meter to measure the resistance across the zener diode as shown in the picture usb2.jpg in the attachment of the original post of this thread, I got around zero ohm (short circuit). When I plugged in a charger to the phone and measured the voltage across this diode, I also got around zero volt (short circuit).

But after the diode was removed by a needle, the resistance across the two electrodes where the diode had been now measured around 900 kohm and the voltage across two electrodes now measured around 5 volt when the charger is plugged in. The phone is charging again!
[Xiaomi Redmi Note 3 Guides, News, & Discussion] xd4d3v:
I managed to burn 2 note 3s, both diodes (charging board, and MB) with a baseus car USB 3.0 cable.

IS it worth replacing the charging board, and leaving the mb zener removed?

I don't think it's worth getting it proffessionally fixed, as the phone price is less than than pro repair where I live.
[Xiaomi Redmi Note 3 Guides, News, & Discussion] philto:
I do not know your model but on the 2 rdn3 pro by removing the ziner only the motherboard, both took over to load but one lost the otg function .. good change. for my model impossible to find a new usb card

[Xiaomi Redmi Note 3 Guides, News, & Discussion] Apcoolboy:
Here is my story, I burned my both diodes (two years ago). What I did is replaced charging board manually (its very easy if you watch it on youtube) as it is easily available at my locals and also cheap. But never replaced MB. I replaced charging board because I am using Agni kernel with fast charging function. So for precautions of the phone. Now due to my cheap usb board, I was getting network issues. So I replaced usb board with old burnt original one. And also using fast charging function. All smooth.

In nutshell, diodes are for just precautions, nothing happen if it is present or not. Believe me, I am using my phone without any diodes on, also with fast charging for two years now. Never faced any issues.

Today I have problem with kenzo connect charger

Suddenly red light blinking only won't boot try several power press with up low volume nothing open device remove battery socket install again connect charger same red light blinking is it Dead ? if someone can help.
[Xiaomi Redmi Note 3 Guides, News, & Discussion] Kudeshido:
Thank you OP, for this quick tutorial and fix.:good:

In my case, Zener diodes were burned on both small board with USB port and main board.

I just scrapped them carefully with thin screwdriver, and now it's charging again.

I was thinking on getting a new phone, but I have more important things to spend cash on, so my kenzo stays with me until it breaks again, so far going strong for 3.5 years and second battery.:cowboy:
[Xiaomi Redmi Note 3 Guides, News, & Discussion] poster74:
Hi,

I have Redmi Note 5 Pro and I Suspect the same issue.

It doesn't charge anymore, it will charge for 1 or 2 seconds and then stop for 2 seconds and start again etc. When it does charge, it charges at about 200mh (as seen from Ampere app).

I replaced with a new battery and USB charging port and still the same problem. I suspect that its the zenner diode on the motherboard.

The only problem is that I don't know where the diode is on the Redmi Note 5 Pro. There is a video that takes apart the entire phone (link below) and from the video I have attached 2 screenshots. To the side of the top usb flex cable, there is a tiny silver rectangle, is this the diode ? Any ideas?

I dont really know how to use a multimeter, but I managed to get 5V with one probe on the the charging going in and the other probe on the bottom usb socket, where the flex plugs in (yellow in the attached pic). However when I attached the probe to the top of the usb flex cable. I could not get a reading. Does this mean that the flex cable connector could be faulty and not the diode ?

I couldnt attached pic, but from the video you can see it at 3:40 and also 4:58

Hello friends,

After trying different roms and kernels there always comes a time when we wish to go back to complete stock for a smooth reliable experience. Here's a detailed step by step guide for this process.

This guide assumes that you are on a unlocked bootloader with TWRP recovery installed and want to revert to complete stock

This will erase all data on your phone. Hence first BACKUP!

Note : I am not responsible for any damage do this at your own risk.

Downloads

1) MINIMAL ADB & FASTBOOT : https://goo.gl/UbFXdA

2) STOCK OOS FILE : https://goo.gl/JAfS2F

3) Stock Recovery : https://goo.gl/2kmbB7

Pre Requisites : A windows computer with a decent internet connection

Oneplus 5T with atleast 50% battery charged

USB Cable

Brain:cyclops:

Steps :

1) Download and install minimal ADB & Fastboot.

2) Download OOS Stock Rom And Stock Recovery.

3) Connect your phone to the PC using the USB cable in file transfer mode.

4) Copy the rom zip and stock recovery image to your phone.

5) Go to settings>about>tap build number 7 times.

6) Go to settings>developer options>enable advanced reboot.

7) Press power button for 2 seconds>select reboot>select recovery>tap to reboot.

8) Once the phone boots into TWRP>wipe everything except internal storage.

9) Tap install and select the stock rom zip and then swipe to install.

10) Tap install>select install image>select stock recovery img>tap recovery>swipe to install

11) Tap reboot>select bootloader and reboot to bootloader.

12) Once in bootloader connect the phone to your pc and launch minimal adb & fastboot

13) type fastboot devices and ensure device is connected and serial number shows up

14) type fastboot oem lock in minimal adb and fastboot and hit enter.

15) use the volume keys on your phone to highlight yes and press power button to confirm

16) wait for 2 to 5 minutes and phone will bootup to a complete stock rom with stock recovery and a locked bootloader.

For everyones convinience I have made a step by step video guide please watch and subscribe if you liked it.

[OnePlus 5T  Guides, News, & Discussion] vibrantliker:
Before this came out I tried the reversal process incorrectly by typing fastboot oem lock as the 1st step (I know it says above you need a brain). Now it seems there is no OS to boot to. I can boot to TWRP and fastboot but my computer doesn't see the storage. Is there a way to push the the rom zip and stock recovery image to your phone via adb? If so what are the commands?
[OnePlus 5T  Guides, News, & Discussion] Stephen:
I believe you should be able to go into twrp, go to sideload mode. Then the command would be abd sideload filename.zip This should then push the rom to your phone and install it for you. It has been a while since I needed to do it, as now a days I mostly keep my phones stock and locked.
[OnePlus 5T  Guides, News, & Discussion] vibrantliker:

[OnePlus 5T  Guides, News, & Discussion] rickysidhu_:
Nice guide but isn't step 10 unnecessary, since the stock ROM will overwrite TWRP with the stock recovery anyway?
[OnePlus 5T  Guides, News, & Discussion] Sisyphus306:
Thanks for the info. My phone's been acting very flaky since I rooted it, so I'm curious to see if returning to stock will make it a little less annoying.
[OnePlus 5T  Guides, News, & Discussion] hypergamer1231:
unlock the bootloader

flash twrpagain

flash stock rom from twrp

flash stockrecovery image from twrp

reboot to bootloader

relock bootloader

reboot

you are good to go

[OnePlus 5T  Guides, News, & Discussion] hypergamer1231:
definitely worth a shot
[OnePlus 5T  Guides, News, & Discussion] hypergamer1231:
sometimes it doesnt and hence before we relock the bootloader its necessary to ensure we have the stock recovery hence the step.
[OnePlus 5T  Guides, News, & Discussion] rickysidhu_:
Fair enough :)
[OnePlus 5T  Guides, News, & Discussion] vibrantliker:
My problem is, although I still have TWRP and fast boot, I don't have an os at the moment and need to get one via adb somehow.

I've tried adb push but can't find in TWRP. My computer doesn't see my phones storage either.

I only have access to TWRP and my files on my phone via my computer, did you ever happen to find a solution to vibrantliker's missing operating system issues? Seems Im stuck and need help if you can
[OnePlus 5T  Guides, News, & Discussion] blas4me:
I had the same problem after flashing LOS. First I had to backup all my files to my computer, then do full wipe, and format. If your getting " failed to mount system " dont worry, stock OOS, will out things back in order. Just flash stock recovery and then sideload the lastest full OTA.

My issue was system was not mounted, I didn't have it selected when I flashed LOS, so ROM didn't flash to system which sent me into a TWRP bootloop. Then I wiped and I could no longer make that selection in mount options......and when I formatted, it wouldn't mount system either...from what I read system was encrypted, so wasn't to be mounted, even when formating.

So I just performed those few steps, and I'm up, and rooted again, but sticking to stock for now. The pain is backing up your stuff to a external source. Hope this helps.
[OnePlus 5T  Guides, News, & Discussion] krabman:
You folks need to remember that you should reboot the recovery after a full wipe and/or format. While TWRP can lose it's ability to mount after a wipe at any time it's just about a sure thing if you wipe across the board . So you do your wipe and then immediately reboot recovery, TWRP will then be able to mount again so you can simply transfer the stock image over.and flash it. If you had that happen and didn't reboot the recovery and shut down the phone after failing to mount, format data again and then reboot recovery and you should be able to mount. Do not wipe after and directly boot to system, this will ensure you also have the stock recovery without having to flash it. From there you can just lock the bootloader and be done although that step has no effect on the system performance or stability.
[OnePlus 5T  Guides, News, & Discussion] dwarf77:
Thanks for the nice guide!

One thing I would like to add is that you can also download the latest stock zip directly from OnePlus. Below the download button of the chosen version you will also find a download link of the current stock recovery image.
[OnePlus 5T  Guides, News, & Discussion] Harthouse:
Also you can go with the latest OOS 5.1.1 (+ stock recovery), for an example, if you are on 8.1.0 and you want to stay on it.

Hi, planning to sell my OP 5T for getting 6T and I have now unlocked bootloader,rooted with magisk and newest OB18 with Blu kernel and recovery.

Now I want get my device like it was out of box,so totally wipe include internal storage and put then newest original rom and newest recovery to phone with adb and lock bootloader

This guide help only with stuff on phone storage and not wipe internal storage so can someone please help me to get phone as it was from box thank you
[OnePlus 5T  Guides, News, & Discussion] Sam Nakamura:
I don't understand really... Phone storage and internal storage should be the same!

Getting back to full stock means basically flashing stock recovery, boot up stock recovery, format data with stock recovery and adb sideload latest stable OxygenOS...

reboot & done

(at least this worked for my 3t and I don't see a reason why it shouldn't work the same way for the 5t)

Is it also possible to install the stock recovery via adb "fastboot flash recovery recovery.img", reboot to the stock recovery, do a factory reset from within the stock recovery and then flash for example the latest open beta?

I keep getting a flash error from TWRP when I want to flash the latest open beta. (I think it is because it is android Pie and I am still on Oreo.)

That's why I would like to revert to stock to upgrade.

TWRP can be a twerp

Figured I'd add my $0.02 here.

I followed the guide in the OP but the stock firmware wouldn't flash via TWRP. I downloaded it several times, even letting the phone itself do it and then snagging it out of the .OTA directory. Every time TWRP would give me an error telling me that my zip file was corrupted.

The phone still had the stock Oreo ROM. I had attempted to root it with Magisk but it didn't work (the system detected root but no rooted apps would work). If I let the phone try to update itself, it would download the update and then boot into TWRP... Which wouldn't flash the update!

My solution was boot the phone into fastboot and flash the stock recovery. Once recovery was stock, I let the phone run it's own update and it worked flawlessly. Once the new OEM ROM was installed (Android Pie) I booted into fastboot again and re-locked the bootloader as given in the OP instructions.

Once the bootloader was locked (and the device wiped itself) I booted the system and turned off the "allow unlocking" option. Done!

Phone is now back totally stock Android Pie.
[OnePlus 5T  Guides, News, & Discussion] Villelj:
What is newest stock recovery? I can't see download link anymore at OnePlus website? Now on OB25 with blue recovery and want my phone like "out of box" for change.

Can I just downloaded newest official rom 9.0.3 and flash it and boot to original recovery? Then close bootloader etc

Recovery comes with rom right?

Edit: I found original recovery link from beta site,is this okay with official rom
