Develop Bugs

Softbrick'd. No idea what to do.

I've got quite a problem.
A few weeks ago, I unlocked the bootloader on my phone and flashed SuperSu to root it.
Today I decided to lock it back for personal reasons, wiping everything.
After it wiped, the phone kinda softbricked. When it turns on the OnePlus logo flashes for a second and turns off.
Won't let me unlock bootloader again, got stock recovery. Tried to use sideload, but ADB can't read the file. My guess it's too large.
What can I do?

I had same problem. Follow the steps. Unlock it again and reboot to the system.
There enable developer option, enable debugging, enable unlock bootloader option.
Rebooted to fastboot mode
Install stock recovery
Adb sideload 3.2 full firmware.
After that reboot your phone to fastboot mode.
Unlock bootloader.
This should do it.

It's like you didn't even read what I wrote...
I said it doesn't boot to system, OnePlus logo appears for a split second and phone turns off.
Bootloader is locked and I cannot flash anything.
ADB Sideload won't read files. Gives the 'cannot read' error.

You know that you can load to bootloader by pressing volume up and power button right?

You should be fine so long as you didn't deactivate the"OEM UNLOCK " option from the developer setting....
do the following
1. press and hold the volume up an power buttons simultaneously to enter the boot loader menu.
2.select start option from the bootloader menu sorry that menu is the boot loader.
3. now connect to pc and use the "fastboot devices" command to see if your pc recognizes you op3 as an android device.
4.type "fastboot oem unlock"
5. flash the custom recovery thru fastboot
5. enter custom recovery and flash your desired rom.
hope this works for you!

And if by mistake I have deactivate the "OEM UNLOCK " what can I do?

I relocked the bootloader. Which wiped to factory reset.
That wipe deactivated the ability to unlock bootloader until reactivated from the system, which I cannot get to because the phone turns off/bootlops before loading it.

This happened quite a few times on this forum, there is really no reason to relock the bootloader on the op3, it is covered through warranty, but u will have to contact oneplus and they should walk u through and send u files to unbrick it if u r lucky

then you better get in touch with the op customer service. they will, from what i know, fix it thru a remote connection sitting.

I have no solution for you, but I wonder if you went back to stock recovery first before you relocked the bootloader? I think if you have TWRP and try to relock the bootloader, this happens. NOT that its helpful to you, but if this is the case and you can verify it, might help others avoid making the same mistake.
As far as your problem is concerned, I would look for unbricking guides. I know I saw at least one guide that lets you recreate the entire partition table manually and make it just like new for the OP2 (and has the company's blessings to do so). So it should apply here as well. Sorry, do not remember where I saw this, but must have been either on xda or the oneplus forums.

I have stock recovery. I did boot TWRP first and let it change system by mistake, but reflashed stock later. That's what might have caused the bootloop once I relocked.
So I guess if you decide to relock in the future, don't flash TWRP, cause it bootloops, even if stock is reflashed.

Bro don't worry now.
I am gonna guide you out of this.
First install an adb package like this.
http://forum.xda-developers.com/showthread.php?p=48915118#post48915118
Now get a toolkit like this.
http://forum.xda-developers.com/oneplus-3/development/toolkit-oneplus-3-toolkit-unlock-t3398799
Try to connect to fastboot and check for your device in the toolkit.
If failed then kill process adb in your task manager.
Now once connected.
Check OEM status and bootloader status.
Unlock if required.
Now.
Push twrp to your phone .
Then boot into it through the toolkit.
Now load a full ROM.
http://forum.xda-developers.com/oneplus-3/development/rom-op3lite-debloated-tweaked-fast-t3404996
Just copy paste it using your file manager on PC.
Them flash first make it boot and then root.
Hope this helped.

Nah, I think this happens only if you let TWRP modify the system partition. But, I have not and am not willing to test it out

Don't test it. I've already done it by mistake.
It replaced recovery with TWRP by allowing the modification of system and even after reflashing stock it'll bootloop on relocking recovery.
So I found something useful then.

Hey, i think i found a solution for you. I don't know if i can post here xda thread links, so search "EDL Mode xda" on Google and the first link it is. Hope i helped

Really need help

So i have searched all over the internet and havent found ant help. My phone is in a bootloop and i can't get out of it, i have tried with Nexus root tool kit to factory reset but just bootloop have tried it twice. Also tried to install factory with TWRP but still bootloop. I have an unlocked bootloader, I also tried to lock it and start with a new factory image but didnät work either . So please help me if you can i'm willing to try anything can't afford a new phone right now.
BIG UPDATE
So now after some work with trying to fx this i have found the problem with it. It's that my phone dosen't install the files that i install with either adb or TWRP. I found this by putting pure nexus rom on the phone and installing it with TWRP and then remove it from the storage. That was when the storage on the phone said it was still zero even when i had choose to install a new rom on the phone. but it still bootloop with the google logo and the four dots that pulse and then reboots.
Another Update
So i tried with installing the pixel rom from the xda forum and it all went well and all with the insallation no errors what so ever but my boot animation changed to pixels but still continue to bootloop still don't know whats happening.

I'm not sure what state your device is in right now. Is the bootloader locked or unlocked? When you tried to lock it, don't try that again, did it lock or did it remain unlocked when you re-booted into the bootloader? Were you able to successfully flash the factory image?
I'd suggest you carefully read thru this and pay particular attention to how to flash a factory image, http://forum.xda-developers.com/nexus-5x/general/guides-how-to-guides-beginners-t3206930

Whell when i locked the bootloader it got locked but then when it bootlooped for one to two hours i opened it again and went to ask the pros at xda. I also read through the guide you linked me and did as said in the tutorial but my phone is still bootlooping right now.

Did you successfully manually flash each of the image files in the latest factory image? Bootloader, radio, system, boot, etc.

Huawei Mate SE stuck on "just a sec" after factory reset with FRP lock on

So, being the stupid person I am I broke my Mate SE one day after purchase ._. I'm posting my entire process just in case anything helps.
I started off by updating to the latest ROM and then unlocking the bootloader, which went fairly well, then flashed TWRP. A lot of versions I found didn't work(Bootloader says Func NO: 11 (recovery image) and Error NO: 2 (load failed!)), but I got a working version here: https://forum.xda-developers.com/honor-7x/development/oreo-twrp-complete-backup-t3764500 .
After that, I installed Magisk, which went well, then Xposed framework inside Magisk, which put my phone in a bootloop. I didn't know what to do, so I went with a factory reset[terrible idea]. Now, my phone has the FRP lock on, and the android setup is stuck on a "just a sec" page, right after selecting language and wifi, so I can't login to my google account to disable the FRP lock.
I tried flashing, but apparently the FRP lock stops me from being able to flash anything inside the bootloader. I do still have my TWRP recovery and a backup of the kernel and ramdisk(sadly nothing else useful, although I do also have dts, dfx, vendor_image, oeminfo and secure_storage) but restoring them or wiping the system again has no effect(still stuck on "just a sec").
After some google searching someone in a thread said that I should use stock recovery to wipe factory data(by restoring the stock recovery in TWRP), and I would be able to get past the "just a sec" problem, but I am reluctant because if it doesn't work, I would permanently lose my TWRP recovery with no way to flash it back(because of that FRP lock). I also tried installing update.app and other stock ROMs from various sources using TWRP, but all of them had a "check_write_data_to_partition, write data error" error. I'm not sure if it's related to FRP.
I think my next course of action is to either a) disable FRP in recovery, b) bypass the setup screen or c) install some ROM on it and somehow bypassing the check_write_data_to_partition error, but I'm not sure how to do any of these. Any ideas or suggestions? Thanks.

Thanks for the help! It worked, and the bootloader says FRP unlocked. It didn't help the "just a sec" issue, but since I can use fastboot flash, I might be able to flash a new rom in it and just ditch EMUI[probably]. I'll play around with it a bit. Again, thanks a lot for your help!

I got everything working now! Just in case anyone had the same "just a sec" issue: it was fixed by flashing stock recovery then doing a factory reset there(I'm not sure how that's different from wiping dalvik/cache/data/internal storage in twrp, but it makes a difference apparantly). Just flashing custom ROMs didn't solve the problem. After that I installed magisk, and then installed this version of xposed: https://forum.xda-developers.com/showpost.php?p=76582399&postcount=11 . I installed the v90-beta3 version before which caused the bootloop, but it is fixed in the next version. Magisk has some issues so the magisk manager can't start with internet(adb logcat says there's a NullPointerException in com.topjohnwu.magisk.database.RepoDatabaseHelper.removeRepo) but frankly I don't need to open it with internet anyways. Now I have everything I need on my new phone! Thanks to mrmazak for pointing me to the right direction.

Need locked bootloader to install 5.0.6 OxygenOS (Oreo) but...

My girlfriend has a OnePlus 3T and is stuck on Oxygen OS 5.0.4, and it doesn't matter if I download the update via the update settings or install it locally or via adb, or use twrp to flash it, I tried all those ways.
Regardless, the update fails every time. I also tried deleting the ota folder, and rebooting her phone to recovery and deleting cache... that doesn't work either. I also tried using adb and typing in - adb reboot "dm-verity enforcing" - still nothing.
I also used the toolkit from here:
https://forum.xda-developers.com/oneplus-3/development/toolkit-oneplus-3-toolkit-unlock-t3398799
and I tried to lock the bootloader. It took me hours to figure out how to get the bootloader unlocked again, cause I had to enter a password to get in, and at the time my girlfriend had no password on her phone at all.
After I figured out about unlocking the bootloader again, I made a password in the security setting, re locked bootloader, still nothing. The password works while phone's bootloader is unlocked, but not while it's locked.
I made a video to further explain and show the situation.

Still nothing?

I watched your video,
Before you relock the bootloader you must install the stock recovery for your device, you can't relock while TWRP is installed, use this guide, (read the guide once completely before you start).
https://forums.oneplus.com/threads/...-3-3t-and-go-back-completely-to-stock.456232/
Also make shure you use the latest ADB drivers Inside (SDK Platform-Tools) from google:

Good Luck!

It worked like a charm. Thank you!

[SOLVED] Trying to unbrick phone from "This MIUI version can't be installed on this device" after failed OFFICIAL OS update.

I have a bricked Redmi Note 5 Pro. Stock firmware, locked bootloader, did literally nothing that would cause this. Just updated firmware (it happened few years ago, just now decided to try and repair it), and after update It's stuck in Mi-Recovery 3.0, with options only for "Reboot", "Wipe Data" and "Connect with MIAssistant", with red text at the bottom "This MIUI version can't be installed on this device" (see photo). Tried everything form this menu, nothing solves the problem. I can boot into fastboot but can't use it as the bootloader is locked and debugging is off. I can go into EDL mode but can't flash as I need to log in into Mi Account, and my sister (this phone was hers) forgot the password and even the account which was connected to this device. I was looking for MiFlash that bypasses authorization but can't find any that is not marked as malware (anyone knows of any that is safe?). At was past the warranty and I've tried to ask few phone-repair shops but the said that is unrepairable.
Any ideas what I can check or try next to solve this problem?
BTW. Does anyone knows why all of this happened? As I already said, never did anything with OS, only updated it which caused brick. My only idea is, as this phone was bought not from official store, that it might be a phone that was bought cheaper in china, then flashed with modified global OS and after update it was replaced with official global OS which bricked the phone. No idea if something like this is possible.
Edit [Sep 19, 2021]: I got somewhere. Used Firehose file to flash whyred global image without authenitcation. Got into system. I can at least go into fastboot and it's detected correctly in windows. Now I'm trying to get root, flash TWRP and any non-stock OS. Couldn't flash directly via fastboot because of anti-rollback check. Tried to do "fastboot boot twrp_rn5pro.img" which resulted in FAIL in console (status read failed - too many links) and "The system has been destroyed - click the power button to shutdown".
Edit2 [Sep 19, 2021]: Looks like my bootloader is still locked and that's why I can't flash custom recovery. But when I look in the phone settings it says that my phone is already unlocked. Checking in fastboot via PC says otherwise. Enabled OEM unlocking, but fastboot still says "FAILED (remote: Token Verify Failed, Reboot the device". Can't unlock it using MiUnlock cause they say that I need to set my account as available to unlock in unlock status on my device, but I can't do it as my device says that it's already unlocked.
Edit3 [Sep 20, 2021]: I've tried other tool: XiaoMiTool V2 (by Francesco Tescari). As the option "My device works normally I want to mod it" didn't work I chose "My device is bricked I want to unbrick it". Selected option without unlocking bootloader (wouldn't work). And it actually auto-detected that it's chinese phone and flashed chinese OS (MIUI 10.3 Stable). At the boot I got a prompt that this device is locked and I need to log into my Mi account (the one I logged in in the last ROM - from first Edit), after logging in it let me go through setup (luckily there was English). But phone still says that it's unlocked while it's still locked in fastboot. So in the end it didn't got me anywhere, but at least I know that orginally it was a chinese phone.
Edit4 [Sep 20, 2021]: Finally solved the problem! Used this tutorial. Did everything like shown on video and at the end I have MIUI 12 with unlocked bootloader (this time it's actually unlocked - checked with fastboot). Managed to flash TWRP using dummy.img and flashing to recovery. Couldn't boot from img, but vol+ + power did the job. With working recovery I can do everything else I wanted to do.

I had the same issue, which I also managed to fix. I thought I'd share what I did here.
My phone was bricked with access to MIUI recovery and Fastboot. My phone was locked, however my phone was not linked to my Mi account, and so I couldn't unlock it using the Mi Unlock tool. The only way to get into EDL mode was via the testpoint method. It's not as scary as people may think.
Many of the YouTube videos on testpoint show that you have to touch the two terminals while pushing the cable into the phone. Several times I was able to activate EDL mode without doing both at the same time - i.e. I could just connect the cable and touch the two terminals (I used a paper clip) and the phone would enter EDL mode. I think it might have had something to do with me pressing the power button. In my case, I had to have the battery disconnected from the circuit to get into EDL mode.
I used the Xiaomi Flash tool. Always remember to select not to relock the bootloader. I think it's stupid that relocking is the default option and that the radio buttons are at the bottom of the program and sometimes not visible on a laptop. That's how I got into this mess in the first place!
One of the things that I think causes the "MIUI version" problem is attempting to install the incorrect stock ROM. The phones may be fussy about which stock ROM they will accept. In my case, I thought the phone was a global version, then worked out that it was probably a Chinese version.
I replaced the firehose files in all the ROMs I attempted flashing with the ones supplied on XDA. The Xiaomi Flash tool reported success several times, but when starting up the phone it would go into recovery with the "MIUI version" message. I tried about six different MIUI ROMs with the testpoint method, both global and Chinese, before stumbling on the one that worked (after replacing the firehose files): whyred_images_V11.0.2.0.PEICNXM_20191023.0000.00_9.0_cn
When I got back into MIUI, I linked the phone to my MI account and then attempted flashing the latest LineageOS (which was what I was trying to do in the first place), using the Lineage recovery. The phone wasn't accepting the Lineage recovery, so I flashed OrangeFox-R11.0-Stable-whyred. I had to boot to Orangefox in order to flash it. You copy the Orangefox zip file to your phone using your computer when you have MIUI up and running, then you enter Fastboot and run the following command from your computer:
fastboot boot recovery.img
From Orangefox, you then select the Orangefox zip file on your phone and swipe to install.
Once that was done, I rebooted to recovery and did a wipe of the phone. It wasn't enough for me to wipe Dalvik/ ART Cache and Cache (as recommended), I had to also wipe System, Vendor and Data. (I tried just the first two and the LOS installation was corrupt, even though it was reported as being successful.) I then copied LOS to a micro SD card, inserted it into the phone and mounted it, before flashing LOS by navigating to the zip file on the SD card, selecting it and selecting wipe to install.
Finally success!
I think the key with the testpoint method is to keep trying ROMs until you stumble on the one that works. If the Xiaomi Flash tool reports success, I think it means you are doing something right. I also wonder if a lot of people who have the "MIUI version" issue have a phone with the Chinese ROM and don't realise it.
Hope this helped someone!

by any chances how do you unlock bootloader if you just bypass the mi account?

the reason is I got my phone Redmi Note 5 Pro on fb marketplace by swapping my old phone, when I'm using it there's no mi account logged in on my phone then I tried to install the latest MIUI 12 by flashing it on MiFlash but I didn't notice that I didn't change the setting on clean all so it locked my bootloader, after I manage to fix the issue about my phone because it doesn't open and it only boot on recovery with a message "This MIUI...." and make it boot by flashing cn official rom, it says that my phone is locked and I need to logged in the old mi account, I already ask the previous owner but he said he doesn't have an access on that account, even the number and email are already lost

If it's locked and you haven't registered the phone with Mi Account, then you will need to use test point. There are a lot of claims that it's not necessary, but I tried many of them and it wouldn't work. I think they are a load of rubbish to get you to pay money. Test point is not that hard, but you need to pick the right ROM.
