[Q] Bootloop (softbrick to hardbrick back to softbrick)

Long story short:
EDIT: I somehow magically (after 2 hours of trying) got into recovery, cleaned and wiped everything and booted into MIUI. Switched to CM 12.1, leaving this thread for anyone that experiences the same problem.
1. I was running CM11-R24, with an early version of the Xcelerate kernel. All was fine and well but today it restarted on its own a couple of times. It would enter a bootloop that I managed to get out of by going into recovery and rebooting from there.
2. Bootloop happened again, couldn't get into recovery.
3. Installed newest twrp recovery via fastboot. No change.
4. Managed to hardbrick my phone by installing a wrong .img of a global version.
5. Managed to revert back to a softbrick by installing the right (hopefully) global version of my mobile phone.
6. I did manage to read a logcat inbetween and I remember there being something about the kernel settings being nulled to default, because there was a failed boot 2 times in a row.

Hard-brick to soft-brick procedure I followed - http en.miui.c o m thread-54139-1-1.html
Used global version: Singapore 50? Going to try other versions
Settings in MiFlash tool (using 2014.11 version). - http postimg.o r g /image/hh122e54j
Current problems:
1. When powering up the phone, it will not go beyond the Mi logo.
2. When trying to enter recovery (volup+power) I enter another loop. It is normally 10-15 seconds of Mi logo, power down, 3-5 seconds of Mi logo, power down. Repeat. I do not stop holding the recovery combination while this happens.
3. I have installed via fastboot all of these recoveries - TWRP 2830, TWRP 2860, Philz latest recovery. After installing each of them, I can not enter recovery mode again. Flashing a new recovery doesn't seem to change that.
I have access to fastboot, currently I installed the stable fastboot rom version "armani_images_JHCCNBH45.0_4.3_cn_e7e373f319".
I can not get adb to recognize the device, only fastboot. Can't get a logcat because of it. If you think I might be doing it wrong, please walk me through the process.
How do I get it back to working condition? The phone was bought in Bulgaria from a retailer, but I don't know which country it was originally shipped from, only that it's a WCDMA version.

Throw it away and get your self some reliable phone unlike redmi , it's a crap lots of issue ... I prefer Motorola .

xperia play bricked? pls help

hi all im hoping u can help me i have an xperia play which i tryed to root using cynogen mod 12 but it fails on install it will then reboot and show the blue cynogen logo but sit thier untill battery pull. i can access cyonogen recovery but thats all. ive tried installing other roms such as 9, 10 and 11 but all do the same thing (although 11 does seam to install/unpack).
i unlocked the bootloader and rooted the phone successfully. i also used flashtool to flash the boot.img.
i have heard i could fix the problem by sideloading another better recovery tool but i dont know how to do that. as off now im stuck in cynogen recovery.
any advice you could give would be greatfully appreciated, at this point im completely out of ideas and if you need anymore info i would be happy to provide it
thanks in advance

Hi,
It would be nice if you linked the exact ROM you tried to flash on you phone. It sounds like the boot.img is incorrect.
You can try flashing this kernel forum.xda-developers.com/showthread.php?t=1804003 . This one is for ICs roms(4.0.x).
Or this one - for Jelly Bean versions(4.1-4.2) - forum.xda-developers.com/showthread.php?t=1861970 .
All you have to do, is boot into fasboot mode and flash the given .img file as boot.img. (The difference between 480p and 720p kernels, are that 480 can't capture 720p videos, but sometimes 720p kernel doesn't work with all roms).

hi tnx for the help the rom i tried to install was cm-12-20150314-UNOFFICIAL-LegacyXperia-zeus
i think your idea would work but im unable to boot into fastboot mode as i used flashtool before and it doesnt recognise my phone anymore ( i dont know if i can use ADB as that option is available on my boot loader)
if you could provide me with a link to how to flash a new .img/rom using another way other than flash tools that would be really helpful. im sry to be such a noob, i have rooted every phone i had and never encountered this problem before and am completely stuck.
tnx again for your help

ok ignore my last msg i managed to flash the .img in fastboot no problem but now it wont let me into recovery mode so i think im stuck in some infinate boot loop no matter how many times i click volume down it just reboots after about 2 mins, anything i can do about that or am i now really bricked?
tnx again for your help

Well you could try to return to point zero by flashing your phone to stock rom and try to begin from there.
You can do that by using flashtool and downloading stock ROM from these forums.
BTW, you can enter flash mode by inserting usb cable and holding search button(i think, you can try other buttons). Your LED has to turn green, blue is fast boot.
Also if your flashtool give you errors, download earlier version (see some other threads about flashtool, there are links to older version). Maybe it doesn't recognize your phone, because of the new version, i've had problems with it too, but i had to download old version and everything started to work as expected.

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!

Saying i'm a dipsh-t I know, I know, I will do better in the future, for now, help a brother out please

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

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?

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.

S10e - impossibility to install Lineage OS

I need to install Lineage OS on this phone.
After multiple tries several months apart, I am still not in success.
Followed all internet tutorials and sites.
I don't want to install any G apps or any special root-things like magdisk..
I only want pure Lineage OS without any extra applications.
Way I tried and probably ended up like before:
Get newest official samsung ROM installed, update, enable usb debigging and oem, go download mode and go factory reset, get back in, sign in to wifi again, again enable develop. settings and usb debugging, go into download mode, take odin and install through the AP option the TWRP now that the phone is in download mode a 3rd time, supposed to be possible now with OEM unlock.
Most of the names on the way I don't understand, just follow tutorials.
I need to get to TWRP to then finally, as used to always, install Lineage from zip.
But I never get rebooted into TWRP recovery, just forver the samsung one, even when firmware is no longer there - after flashing in ap option the twrp tar again it never boots into TWRP afterwards.
Is there something else i must do? is not getting into oem unlock and flashing TWRP enough to get there?
And after, will the zip install finaly get me to have lineage installed?

Did you try the official guide?
https://wiki.lineageos.org/devices/beyond0lte/
I hope I picked the right phones, otherwise check devices overview.
Alternatively, perhaps this helps:
https://forum.xda-developers.com/t/...-a-graphical-installer-for-lineageos.4509995/
PS: Usually LOS doesn't do TWRP anymore but comes with its own recovery (a/b)

Why they don't do TWRP now?
I saw TWRP tuorial fot s10 on tutorials and it worked

Yes, it's still there but perhaps you post a link to your guide (or ask there). To me it seems you had TWRP just in your RAM but not your phone?
As for me, I finally gave up on TWRP and use the "crappy" LOS recovery Have way more important things to waste my time on...
PS: Sorry to bring such "bad" news, wasn't too happy with that change myself

Great, I finaly made it work.
I followed the site with turotial on installation and did not try TWRP
First I had to install samsung ROM again
It turned out to still stay unlocked so went straight to download mode and this time flashed Lineage recovery sucesfuly with heimdall
Then it booted up and a half samsung sreen made it seem like there is trouble
but Lineage recovery launched
The adb load from PC did not work so i chose to instal zip from SD even there
Now Lineage is installed
Still don't know how much is randomness, luck and so on
But it's done and hopefuly repeatable
