STUCK ON REBOOT [LOGCAT included]

hi everyone
when i reboot my device by any means (from inside of android, recovery, even adb reboot-bootloader), the device never finishes the reboot. interestingly, when i have it plugged into windows by usb, when doing the reboot i hear the usb disconnect sound, then the usb connect sound, then it just stays black screen and is unresponsive. only fixed by holding power or power+down button.
some info:
bootloader v 4.02 // twrp 2.7.1.1 // liquidsmooth current nightly
however, this problem happens on stock rooted as well as all custom roms
i have included a logcat of the issue (never made one before but i think i did it right) if someone can please help me, i'm thinking i may need to return my model.
thank you! :fingers-crossed:

Have you tried flashing stock images using fastboot?
It seems like the system can't write to /data directory, maybe flashing everything again will fix that issue.

I did flash the stock images (the latest 4.4.4) and unfortunately still had the same problem. i'll give it another shot today though to see what happens
EDIT: performed the fastboot flash with the factory images and had the same issue. tried philz recovery and wouldn't turn back on after selecting reboot. checked permissions on /data and /system and everything was RW. i tried remounting both as well to no avail. must be a hardware issue i feel like at this point

*Try flashing through a different custom recovery.
* figure out how to use the flashall.bat script to flash a new recovery, bootloader, ROM and kernel.
*Try fastboot boot for the recovery as opposed to fastboot flash. (I'm not sure if this will do anything)
*try wugfresh toolkit soft brick unroot+flash stock
Ps: this is just a list of ideas. Flashing a working ROM should mount all of your directories.

Thanks for the suggestions, though trying those methods unfortunately hadn't done it either. Eventually, the ability to reboot simply showed up just the other day. I'm not too sure why it did and wasn't working before, but I kind of think it needed about 1-2 days of being powered on while connected to a charger. Previously, I would charge it only every few days with the power off and unplug it to use it. That's the only difference I can spot for anyone else who runs into this problem. Keep it connected to the charger for a day or two with the power on.

Stuck on team win recovery project please help

I have no idea how to root or anything like that, I bought this oneplus 3 and had a update a week later.. so when I did the software update it took me into teamwin recovery mode and now I don't know how to get back into my phone please help....

Did you buy the phone second hand or did you try to flash TWRP yourself? It shouldn't have TWRP installed by default.
Regardless, you can use TWRP to flash the latest update.
Given that you have TWRP, I'm assuming that you have an unlocked bootloader. Did you notice a warning pop up everytime you reboot your phone before? It should say something along the lines of "your device has been unlocked and can't be trusted". If not, you'll have to unlock it (it wipes your phone in the process).
If the bootloader is unlocked, you can simply download and flash the latest zip for OOS 4.0.3 in TWRP. This will update you phone and replace TWRP with the stock recovery (so you don't run into this problem again in the future when installing an OTA). If you don't intend to modify your phone in any way, then this is all you need to do, your phone should be functional.
There are plenty of threads with detailed guides on how to do all of this.

I'm also stuck on TWRP after stupidly downloading the latest OTA and I don't know what to do!
Phone won't boot normal, just goes off.
Situation:
- Bootloader, Fastboot and TWRP wil load.
- Device seen by windows
- Zip install in TWRP gets stuck at 'patching zip unconditiontally'
- Another zip flashes, but gets stuck at the end, no reboot option (manually but that's not the way)
Can someone please point me in the right direction? I don't care if I lose data, just want my phone back!

Simple, check the OnePlus D/L sites for this one http://oxygenos.oneplus.net.s3.amazonaws.com/recovery_op3.img and flash it by TWRP or fastboot to RECOVERY. Boot once with the official Recovery and all ist fine again.

This is issue of using a faulty twrp so for that when ur phone us booting up go to fastboot and flash twrp 3.0.4-1 and everything will work

Similar Problem here:
just wanted to flash latest OOS 4.0.3, so I flashed back stock recovery with flashify and rebooted into recovery mode to flash the already downloaded OOS 4.0.3. zip. That's when it began to go poop! After rebooting it just went dark with no Chance to power it on again! No dice with power button, Volume up/down + power button, nothing! Not even the LED's are blinking when plugged in. So this one seems to be basically dead!
I got it once booting again after randomly pushing the buttons (after x minutes!?), but everytime I reboot the phone it just shuts off without beeing able to power it on again. At the Moment it's dead!
Any ideas what might happened? If I get it on again, should I immediately reset it to factory Settings?
I am kinda lost here! Any help/ideas would be much appreciated!

Flashify? Never used it and never trusted apps which flash stuff on a running system. Use fastboot and reflash the recovery partition. Link to recovery is in my former post.
fastboot flash recovery PATHTOIMGFILE

Thank you for your advice! Still a lot to learn! Got it up again, will try as you suggested!

It appeared that my stock recovery file was corrupted , but all is fine again! Thank you very much!

I may have been the person you traded with to get the OnePlus 3, but I took the phone back and after 5 hours I got it up and running.
The phone would boot to TWRP, but even after wiping the entire system and dragging a ROM zip to the internal storage, reinstalling did nothing. It just kept booting back to recovery.
The solution entailed the following.
Download stock recovery IMG. Flashed through TWRP. Rebooted recovery and now was back to stock recovery.
Download the official OxygenOS ROM zip from the OnePlus website and changed the name to update.zip
Next I downloaded Android studio for access to ADB. I had never used ADB before, but I knew this was needed to push a file to the phone.
Needless to say, ADB kept freezing my computer when I would type in the commands to side load.
I deleted Android studio and installed a minimal ADB/Fastboot I found online. I opened my command prompt, typed the command for sideloading, and immediately got my installation starting. It took about 10 minutes to fully install. When it was finished, I rebooted and had a fully functioning OnePlus 3

[RECOVERY][UNOFFICIAL][TWRP] For Sony Xperia T3 D5103 (seagull)

Hi guys, I decided to start modding this smartphone, now that I have a computer capable of compiling in a few hours.
I ported TWRP 3.0, based on Omni 6.0 source to this device. There are a few things not working and I need other people's help and feedback.
READ FULL GUIDE AND NOTES BEFORE FLASHING!!!
-Necessary steps:
Unlock bootloader. Here's a guide from Sony
-How to install:
1)From computer, open a terminal (Linux and MacOS) or command prompt (Windows) where you saved the file (download below). (Linux And MacOS. On Linux you'll need to flash with sudo) or where you have the platform-tools (Windows)
2)Poweroff your phone.
3)Boot into bootloader by pressing Volume+ button while connecting the usb cable into the usb port (the usb cable has to be inserted into the computer's port too, to successfully boot into fastboot)
4)With unlocked bootloader, type fastboot flash recovery twrp_3.0.2-0-seagull-UNOFFICIAL.img, if you renamed the files, substitube "twrp_3.0.2-0-seagull-UNOFFICIAL.img" with your file name or the directory where you saved the file.
5)When you see the OK message from fastboot, disconnect your phone.
6)Press Power, Volume+ and Volume- untile the phone vibrates.
7)Release Volume+ key. When you see the Sony logo appear, wait 3-4 seconds and then release Power button.
8)You should see TWRP bootscreen after a few seconds
-What's working:
Almost all. I could succesfully flash GApps and Root packages from this recovery, Backup, Restore and Wipe partitions. Settings work fine. Terminal and File manager work.
-What's NOT working:
Can't read files MicroSD or USB-OTG, can't browse in them and can't wipe. Investigating about it.
-Download:
(GDrive) Version 3.0.2-1
(AFH) Version 3.0.2-1

30/04/2018: I think I fixed the screen problem by using the Lollipop kernel instead of the Marshmellow one
Thanks Everyone

Cool, although upon booting into recovery the screen isn't operating normally, similar to what happens when flashing the fxp lollipop. Might be because I'm on stock ROM/kernel though.

What do you mean with "isn't operating normally"? The screen only displays coloured bands? If so, it should have be fixed, maybe only the download link is wrong. Tell me, I'll fix in a minute

Yes, sorry for not being more specific xD, I'm indeed getting the white-grey bands on screen.
---------- Post added at 11:25 AM ---------- Previous post was at 11:10 AM ----------
It's possible it's the lollipop kernel that's to blame, since I've had the same problem with other lollipop builds.

Tried both versions, so it's probably my device.
(However, if it is it's fine, since I do have working twrp.)

Does this build require an updated bootloader to allow access to the "recovery" partition?
I've got a T3 with a successfully unlocked bootloader, but fastboot gives an error (something about a missing partition table) when I try flashing anything to recovery.
Google tells me that Sony released an updated bootloader some time ago which ought to make a recovery partition available, but I cannot find any active links or instructions for downloading and installing it anywhere,

Don't know

One of my two seagulls came back from assistance and I tried to flash TWRP on it without any problems. I don't know if it had an updated bootloader or what, but the firmware was stock

In order to flash recovery, you first need to download and install the Emma flashtool and restore your phone through it. That will add a recovery partition so you can flash twrp. (The Emma flash tool supports only the D5103 model of the T3 as far as I know)

I tink you will have the same as the eagle (m2) device, you need to update your bootloader and then flash recovery...

Hi
I'm playing with my old Xperia T3 recently and I was able to unlock bootloader and install your TWRP on my device. I'm able to boot into recovery with the method you described. But since my power buton is in a quite bad condition, I'm looking for another way to boot into twrp. I rooted my Xperia with Magisk and I tried to enter recovery from it, but the phone just rebooted. The same happend when I tried to enter recovery from terminal. What can be the cause? Is there any other reliable way to boot into your twrp?
Cheers

Maybe you can try by holding down the volume down button when rebooting, it may work.
In other case, I think the only option is fixing the button

TWRP recovery not working on Blackview BV9500

Hi everybody,
I try to root my Blackview BV9500 by installing first TWRP recovery. I use fastboot mode on a linux laptop to do that.
I successfully flash the twrp recovery image, but after that, the phone don't boot in recovery anymore.
It try to boot into recovery, but it reboot in normal mode a few second after.
I tried also with the cmd "fastboot boot recovery.img".
When i flash back the original recovery image, it work, i can boot the original recovery without any problem.
Does anyone have the problem?
Some one can help me to find a solution?

I, too, am trying to do this. I have not yet flashed it... I was going to use the fastboot boot command to boot the recovery kernel before permanently flashing it, to make sure it would work, and in my googling I stumbled across this post. Serendipity! [Edit 3: Although, reading your post again, I see you tried that as well and it didn't succeed for you. For me, it simply tells me remote: command not found, so how were you able to even get that to work?]
All that said... I have the BV9500 Pro, specifically for the two-way radio, so I'm going to try to keep that little tidbit of hardware working in the process. I mainly just want to tweak the menus a bit, tweak the quick settings, get root, delete the Google crapps I won't be using...
On to your problem, though, I can't help much but maybe if we post back and forth our successes and failures we might be able to stumble through it together?
First, I assume you already have unlocked your bootloader? [Edit: Honestly, I'm not sure flashing the recovery would be allowed without first unlocking the bootloader]
[Edit 2: Perhaps this thread might be of help. Different model, but often the hardwares used by manufacturers are similar enough that the same steps generally work. ]

Thank you for the link, maybe i need to flash the complete rom with the twrp recovery with spflash tools, and it will work.
I will try and let you know, but i will make a backup of my rom before flashing it!
For your problem with fastboot, maybee it's because you need to install it. You can use the command "sudo apt-get install fastboot" on a terminal window if you are on linux.
If you want to enter the recovery mode, you don't need to use fastboot, you can simply enter it by pressing Volume Up and Power buttons together for a couple of seconds when your phone is off.
When Boot Mode appears release all keys.
To flash recovery with fastboot, you need first to enable the developer mode on your phone (go to "Settings > About phone" and make 7th tap on the build number, the Developer options will be unlocked and available), and unlock the bootloader of course.
here what is the process i made to flash the recovery :
- i use the command "adb devices" to check if the phone is well connected. (response is like "BV9500S320001179 device")
- then i enter in fastboot mode with "adb reboot bootloader" (phone reboot and ask confirmation for fastboot mode)
- check with command "fastboot devices"
- unlock the bootloader with the command "fastboot oem unlock" or "fastboot flashing unlock".
- flash the phone with the twrp recovery with "fastboot flash recovery recovery.img"
- reboot the phone in recovery mode with "fastboot boot recovery.img"
Normally the phone boot in twrp recovery.
Hope that will help you too.

I am too facing this problem. In case you got any solutions please let me know too.

Yup. Already had fastboot installed for the LG G5 this phone replaced, the Galaxy Note 4 the LG replaced, the MyTouch 4G Slide the Galaxy replaced, my wife's old Galaxy S5 I used in the interims... LOL, I've got a working install. No, the "Remote: command not found" was returned from within.... Whether fastboot or adb, I forget now, but I was able to get the file to flash eventually, after reading your first post, but unfortunately the phone would not boot to it (nor Android). I thought I'd bricked it. Twice this happened. Each time, after about 5 minutes, it eventually booted to Android.
I flashed the recovery from the ROM in the link Blackview sent me and was able to boot their recovery just fine, so there's something in the TWRP that my particular phone doesn't like.

Thanks, I keep forgetting which keys to hold for recovery versus bootloader, so I use the adb command to be sure without having to keep a notepad nearby.
Clearly I don't do this as often as I used to.

Now that was something I haven't done since the T-Mobile G1 days. My understanding was that you CAN boot a recovery without flashing it first if you"fastboot boot {image filename}" but that didn't work for me either. I'm also assuming that the filename to flash can be anything because the device stores it to a partition, so it shouldn't have to be specifically "recovery-verified.img".
The recovery you have... Were you ever able to boot to it? If so, would you be willing to share a link to its download source, please?
I've got to run for a prior engagement, I'll check back later.
Thanks!

I guess i find the reason why the modified recovery image won't boot.
I find an interesting information in a post of osm0sis (https://forum.xda-developers.com/showthread.php?t=2073775) were he say : "some newer MediaTek (MTK) devices use special image signing that adds a "BFBF" pre-header signature, so images will unpack/repack but most likely won't boot unless run through their internal signing tool."
After more search, i find an interesting publication (http://www.lieberbiber.de/2015/07/04/mediatek-details-partitions-and-preloader/) witch confirm that.
They say in conclusion of the publication :
"Yes, I can confirm that SignTool is able to add digital signature information to firmware images. Signed images have an additional header “BFBF” and some fluff which SP Flash Tool checks on a secure device. Apparently some manufacturers merely used the default MTK key for signing the images, making them no better off than a typical insecure MTK device."
So we have to find another way to install magisk to root it.

Root 9500/pro
Mine rooted already....you guys can check on 4pda russian forum
Note : do not use the 17.1 version of magisk there because after reboot the device will freeze if you resboot after twrp 1st install...instead flash 17.3+ or 18+ right after first install of twrp...
EDIT : dont mind the russian language in TWRP as you can change it to english once there

you can just download latest firmware and simply backup NVRAM etc with sp flash tool also flash with sp tool, you will have then working twrp with disabled encryption. there are tons of post regarding using sp flash tool on this forum
im using same phone and did these actions on first day and did not have any problem with twrp or magisk

Hi,
I've bought this phone in Pro version. I rooted my phone using needrom.com/download/bv9500pro-bv9500-root/ and adb after unlocking bootloader. Then I failed with errors. Then I used SPFlashTool in root mode with official 2018092919_s32v63c2k_jk_pro.rar rom (I don't find it anymore on the net but 1) I got it on Blackview official forum and 2) I have the file on my own PC) with format+Download and replace recovery with TWRP from Jemmini from 4pda.ru before flashing. OK.
Then I rooted again: format /data with TWRP, then install disable_encryption.zip, wipe dalvik, reboot on TWRP, then install Magisk, wipe dalvik, reboot normally.
Beware: TWRP is in Russian language at first boot, so to get it in English, first slide the first slide (allowing writing), then select 'Настройки', then the globe on top, then English, then 'Установитъ Язык'.
Hope this helps.
Then, this is my first rooted phone, so I plan to make a custom rom without Gapps (then maybe without Mediatek Ones and agold too) and remake all functionning with apps from Fdroid. Help needed on a manner of removing a system/vendor app properly. Help needed too to add V4A, as I could see max version supported is Nougat. I announce this here as my first post, but my project will be a full post. If someone want help please ask here or MP me
Note: an update of magisk is out (official 18.1), I installed it and my phone tells me a message that facial recognition was not working anymore then it only boots on TWRP... I reflashed it and my phone boots normally again. Wait and see...
Thanks to Jemmini from 4pda.ru again.
Bests Regards

It'd be great to have another rom but I'm facing a problem with battery life. Basically mobile network standby drains 5000mah battery every day i turned off from developer option but still problem is there. I have checked every single post on Google but nobody has solution for this. U guys face this problem too?

New update has been released today. It solves some battery issues, but be very careful.
I installed it, having TWRP and now I'm stuck in TWRP. I've tried to wipe everything but I'm still in TWRP.
I'll try SPFlashTool ... hope it works.

Everything restored & updated.
Using SPFlashTool I flashed all files included in 2018092919_s32v63c2k_jk_pro.rar (including original recovery instead of TWRP).
After that, Android booted and then, using OTA, I updated to latest version.

Could you please send me the link? Can't find it on blackview forum

The latest version is not on the forum. I installed via OTA.
But if you mean the previous firmware, there is one link on the blackview forum: http://bbs.blackview.hk/viewtopic.php?t=480235#p795494
SP Flash tools are well documented here: https://forum.xda-developers.com/showthread.php?t=1982587
And a complete list of blackview bv9500 / bv9500 pro files and instructions (in russian): https://4pda.ru/forum/index.php?showtopic=931296
Hope you find what you are looking for.

@kanadali,
for the moment I'm not facing battery drain because there is not simcard in it at this state of my modifications, sorry.
@Reflected_God,
I think this is the link I used, I use the 2018092919_s32v63c2k_jk_pro.rar rom for base.
For all others who faces big problems like me (facial recognition not working then reboot on twrp only, I could reflash my phone with SPFlashTool, the rom and twrp from Jemmini/4PDA in russian only (others don't work for me). I used Format + Download in root mode on Linux. Then format /data with TWRP, then install disable_encryption.zip, wipe dalvik, reboot on TWRP, then install Magisk, wipe dalvik, reboot normally. Do other things. To remove gapps I disabled/force stop it before remove with TWRP. Others apps I can't disable simply remove with TWRP. I test if I encounter bugs but none for the moment. If someone wants to know what I do I've made a LibreOffice Calc sheet log, which evolve when I have time
Hope this helps
Bests Regards

Need Files or a GOOD guide. bv9500 NOT PRO.
If someone could upload the exact files that they used, and the exact same steps, that would be great. Please mention what stock version you have and a link to the image if possible as well. I've followed numerous different guides, with multiple different rom versions, multiple different recovery imgs, used sp flash tool and adb/fastboot multiple times, tried making sure everything was unlocked before each try, have all the necessary drivers, and the closest I get to a functional twrp recovery is a green line that appears at the top of the boot screen before it reboots. Ive tried going to the source, the russian site, but all of the links are 404ed. if not for me, then it would be great to just have this all in one place. Thank you please future hero.
Please include exact program versions (ex SP Flash) as well if not zips of them. I am sorry to be asking so much in one post however I truly didn't know what else to do. And I am typically very good with my google fu xD
I currently have build number BV_BV9500_V1.0_20181026. That seems to matter I believe.

I second the notion.
I have the pro model. I have considered rooting it, but honestly, the phone works well enough as-is without root (for me). However, I'd LOVE to be able to play with different ROMs on this device **AS LONG AS I CAN MAINTAIN THE TWO-WAY UHF TRANSCEIVER FUNCTIONALITY** (i.e. not some "needs-a-network-of-some-kind" "walkie talkie app" like Zello but the real UHF two-way), and I'd LOVE the ability to play with the files associated with the radio to really explore the hardware's capabilities.
Unfortunately, this phone seems more popular in [North]eastern Asia than anywhere else so I don't think we're likely to get much on this forum regarding it unless and until BV become a popular name in the western hemisphere.

TWRP for Sony XZ2c instead of Lineage Recovery?

Hi everyone
After some research, I can't find a succeful way to install TWRP recovery instead of Lineage stock recovery.
It's really embarasing because I'm currently setting up my brand new XZ2c compact to run the way I want it to on Lineage OS 17.1 with Magisk and Xposed modules, and I experienced 3 or 4 endless bootloop that led me to fully format my phone after bunch of hours setting it and tailoring it up... Huge waste of time, frustration overload, as you could expect. So, I really miss tremendous TWRP backup fonctionnality I used to run frequently on my old Z5c... :crying:
Does anyone here as figured out how to replace Lineage stock recovery on this device? Is so, I'd really to hear him out
Have a good week-end!

You don't install a recovery, but only temporally boot one

Thanks for your (minimalist) advice. Literally just lost 1 hour fixing the bootloop it just caused by following it, I'm delighted.
Behind my post, I was hoping to find someone who could explain a bit more the process of replacing/flashing/booting/(wateveryouwanti'mnotanexpert) a recovery, and at the same time avoiding me wasting more hours in bootlooping/formating/reinstalling. Hopefully, this time I succeed to came out of the bootloop without formating and reseting eveything, but I almost lost my nerves.
All of this is a bit cloudy for me, could you (or someone else that would give me a little of his time to) be pedagogue and explain clearly the whole proccess (and especially what you should avoid if you don't want to get stuck in a bootloop/getting scarying corrupted device message) ?

No one?

Wrong forum. Search in you device section.

Hi guys!
Today I tried again to install TWRP on my Sonyh Xperia XZ2C because LineageOS Recovery doesn't provide Nandroid backup, which is a shame.
I tried many ways described over the web, none of those worked, and I ended up with a boot loop at startup with that naughty message "your device is corrupted it cannot be trusted and will not boot". I can't boot to Lineage, neither to recovery. I'm stuck.
With device turned off, I can eventually press volume down, plug it to computer, access fastboot mode (blue led), flash+boot the LineageOSrecovery.img, then the device restart, Sony logo appears... and that's all, I'm stuck with logo in boot loop, and I can't go anywhere further.
I tried to change boot slot (without knowing if it could help with this problem at all) but I alway get "unknown option".
I'm panicking right now, I can't find any way out to this bootloop, if someone could help it will be sooo appreciated!
I tried hard to find a solution for 4 hours now, I'm completly stuck and I can't even sleep. That's why I finally reached out here.

In fastboot mode you should be able to flash stock rom

Is there any way to make the device boot on the Lineage partition without wiping everything?

For an unknown reason, I succed to boot on Lineage Recovery (not TWRP) this morning. I flashed LineageOs rom.zip using adb sideload. After rebooting, the recovery tolds me that I had to wipe everything because the system partition seems to be corrupted, so I did.
I'm a bit tired to lost everything since I made all of this to do Nandroid backups with TWRP........ but I have a fresh new install, my phone works again so it's fine.
But I still need to make Nandroid backups.
Kurtn, you seem to have skills and knowledge. As you can see, I didn't succeed to boot Twrp since october 2020. I don't see why it would be impossible with my device, I'm probably messing something somewhere.
Would you share your knowledge and help me booting/flashing TWRP without bricking everything again?

Could you make an answer instead of a single smiley?

Sorry, i cant. I don't backup and I don't have an a/b device.

Ok, thanks anyway!

Btw.
Code:
fastboot flash boot recovery.img
DOES install the recovery, since it's permanently flashed. Don't know why they (lineage) didn't change that.

However @tomboudiboudi , you could boot twrp manually using
Code:
fastboot boot twrp.img
With that, twrp should appear and ask for a password to decrypt your userdata partition.
If that works, you could try to flash boot this very same twrp.img. Maybe you need an additional twrp.zip too which will be sideloaded within twrp itself.
A note for you which might help: I wanted to update my lineage recovery manually using fastboot (older lineage recovery to newer one) and found that nothing (except fastboot) was booting at all after flashing this.
However, after dirty flashing lineageOS.zip, everything worked fine again.
Keep in mind that flashing a recovery will modify your boot.img. If this one doesn't work / is corrupt etc., your os won't boot up.

I fear you still haven't realized, what a/b means. The classic concept of having a recovery partition, where you can boot twrp at any time - doesn't apply.

You're right, there is no recovery partition.
As I said: Flashing a recovery.img will modify the boot.img.
