[Q] (Nearly?) Bricked M8 - Help

Hello there good folks of XDA,
I'm at work right now and my phone is at home but here is the story of what went down last night.
I tried to root my phone, after installing TWRP and superuser I ran a root-check app and it said that I was not rooted, so not thinking I tried the 'fix permissions' function of TWRP and then everything went haywire.
It's an international version M8 that I've had rooted before but reverted back to stock to get the lollipop OTA update​By haywire I mean the phone booted up but no widgets displayed and most of the apps still appeared in the app drawer but nothing would open.
Instead of seeking help at this point I went to town on trying various things :silly:
The last of which was try and flash a boot image to it, but I think I must've used the wrong one as after doing that it's now stuck in a boot into TWRP loop.
From when I had previously rooted the phone I had a boot image (I think) 2.22.401, it matched version on the recovery file I used when reverting to stock in the past so I thought it would be fine​
I've still got a terminal open at home with all the results of the fastboot getvar all command but from memory my CID was HTC_044
Can someone help outline the process and possibly even the files I need to reflash my phone into a working order. (it doesn't need to be 'stock' but that would be best)
I use a mac by default but I do have a windows machine at the ready I can use so feel free to base any tips on doing it from either platform​

Post the getvar all output, minus IMEI and serial number, and we'll go from there

Thanks for coming to my assistance but in the end (after a few more slight failures) I managed solve the problems myself.
I believe that my first problem was using a not up-to-date version of TWRP (2.7) with Lollipop; the first symptom was my attempt at rooting my phone, the process appeared to go well but just wasn't working properly.
My second problem was 'fixing permissions'; after doing that my phone went totally haywire and while it would boot into android nothing would work properly
After going to a previously used stock recovery and getting nowhere I went back to the same TWRP I started this with and still had fixed nothing.
at this point I did a factory reset from the recovery mode and while that got me booting back into android I was being swamped with error messages and couldn't get past setup wizard crashing.
At this point I flashed the wrong boot image and had a nearly impossible time getting to the system boot menu instead of TWRP being what it always went to. Eventually I must've got the timing right with the buttons or something because I got back into the system boot menu and could access fastboot.
Once in fastboot I downloaded a full nandroid backup and restored it, my phone was working again... or so I thought, it was still suffering from permissions problems
at this point I re-rooted it with the latest TWRP, got SuperSU working properly, did the 'restorecon' command with a terminal app and now the app crashes I was getting have stopped and I can see and write to the phone memory.
After trying to test everything I could think of on my phone today I think it's finally fixed.
I tried to do a partial/selective app+data restore from a nandroid backup I took of my own phone just after the 'fix permissions' event but it didn't work properly so in the end I manually re-setup my phone. I do run an sms backup app so overall I only lost time...

V410 7.0 LTE bricked

Ok guys I am pretty sure I fubar'd my tablet.
I am stuck in a recovery loop. When I start the tablet it just goes back into recovery. Which if I still had TWRP I think I could still do something, but I flashed cyanogen recovery trying to flash cm13 since I cold not get anything else to work. I cannot boot into download/firmware update screen. The screen just flickers a little and goes dark.
A little background:
Started when tablet forced install of 5.0 update and I was in a recovery loop. I flashed 410 test build, rooted, flashed twrp, installed stock rooted ROM. Everything was fine. Then tablet did it again, this time I just flashed rooted ROM and factory reset. Even took the steps to fix the white lines and storage issues. Was working fine. Got home a few days ago and I was in a recovery loop again. But now I don't have the bootloader screen/download mode/firmware update screen (whatever you want to call it) so last night i tried to download cm13, Gapps and cyanogen recovery with no avail.
I can access adb on my PC while in recovery, but when I try to access ADB shell I get unauthorized something or other. Because I cannot authorize USB debugging, because ROM won't boot. I tried to flash stock rooted ROM from cyanogen recovery and it says not signed or something like that.
Does anyone have any ideas? I really think I have screwed the pooch here.

if you have a stock recovery image flashing it is easy, i had a LOT of troubles with my v410 and still am working with it. i have mine rooted, just with TWRP though, i cant use xposed framework, which negates why i rooted this in the first place. anyway, through much grit and determination flash your stock image after wiping what needs to be wiped and doing all other necessary things. Then, you must download kingo root, supersu, superuser. flashify would help with the flashing i hear, but it has troubles with the v410. kingo root was an apk i managed to find buried under a million viruses on the 34th page of google..or something. rooted mine in one click, from stock to reboot to twrp root.. many glitches.
I need help myself, deleted my "Phone" system app, causing me to lose connectivity with my data plan. cant seem to restore it, and flashify nor twrp has been able to flash a custom recovery, or a backup, im at a loss.
Help? We seek the same thing.

Ok but how do I flash the stock recovery image. I can't use fastboot. ADB says I am unauthorized.

Anyone have any other ideas?
I am at a complete loss. I am by no means a developer, but I do know my way around. I really think I have FUBAR'd this one.

Kind of stinks, I give up. Anyone want a bricked v410?

Trying to update while rooted...

Hello,
today I accidentally tapped on "Update" (to 7.1.1) on my rooted Nexus 5X... Something you usually shouldn't do, but it was 2am and I was tired and.... Doesn't matter. After this my phone rebooted and almost instantly showed the dead android with the message "No command". And now I'm stuck there. After rebooting I still land there.
Since the error message almost instantly appeared and since I still can boot into TWRP (3.0.2-2), I think the update wasn't installed and I hope to find a way to avoid the factory reset of my phone. Do you have some tips or possible solutions what I should do in this case?
Thank you for your help.

Its odd this happened, when rooted and twrp installed. in my experience, the update will just simply fail and it will boot back up.... in your case, it sounds like something flashed but the phone didnt like it.... All I can think of is if you cant get into twrp, boot into fastboot and flash the factory image from google, you will loose all data though.....
EDIT, RE-READ you post, if you CAN get into TWRP, try flashing a backup... you should have a backup I hope, lol... First rule of root and flashing is make a backup asap....LOL

When I rooted my phone I did a backup. But the problem is, it was several months ago. So I tried the only method I could save all my data. It wasn't safe, I knew this, but no risk no fun.
My solution was: Download the ota update from Google and flash it with TWRP... Voila! My phone boots properly with the new update... But this method is like I mentioned before not safe and can probably cause a boot-loop with an overwritten recovery. I had to flash my recovery again, but everything works fine now.

Stuck on google logo boot screen after twrp recovery & then factory reset

Hi guys, bit of a saga here so bear with me...and also it should be mentioned I have little experience/understanding of tech stuff, so that isn't helpful either lol
I've had a Nexus 5x running 7.1.2 for not quite a week; it came with an unlocked bootloader (strangely). Tried to do the usual install twrp & root as I've done with previous phones (all pre-nougat) but all attempts failed. Couldn't boot into stock recovery from the bootloader at all, it would just boot into the system. OK, next thought was that an OTA upgrade to Oreo might work to restore a recovery - but got the BLOD (naturally lol). I found a fix in a modded 4-core Twrp 3.2.1 -0 fbe img + workaround injector zip from osm0sis & XCnathan32 which by some miracle worked.
So far, so good. Ffwd a few days and google play store keeps crashing on opening; I had the feeling that some glitch happened while it was updating, so I tried all the usual fixes like app cache/data wipes and uninstall updates/renistall google play, delete google account etc which failed. Next I tried a cache & data device wipe through twrp - also unsuccessful. Finally, I thought the only thing left to try would be to restore a backup I made on twrp - this led to the current issue of not booting, stuck on the google logo screen. I even thought what the hell! and attempted a factory reset with twrp - same result, where I am now. Google logo screen, however I still have an unlocked bootloader.
Would anyone be able to suggest where I might go from here? I'm pretty sure the version is N2G48C, if that helps.
Any suggestions very much appreciated...wouldn't mind getting to the 1 week mark with a functioning phone lol

Saga #2
Still no idea what's going on. I realised that I'd backed up and recovered the system and vendor .img files, which according to this thread would be a cause of the issue https://forum.xda-developers.com/nexus-6p/help/stuck-google-logo-twrp-backup-restore-t3320840/page3
So I made another backup without those images, did a full wipe and restored it - still does not boot, still only sitting on the google logo. Tried next to open a cmd terminal to see if I could reflash a stock image, but adb could not connect (maybe because the phone would have been on charging and not file transfer mode?)
Last resort as I saw it was to try the NRT, and see if it would flash stock via the bootloop/softbrick option. Process seemed to be OK, judging by the log - but it did not reboot to the system. Now there is a looping bootloop between the google logo and the unlocked bootloader warning.
Following wugfresh's instructions to factory reset from the recovery (the phone won't turn off via the power button so I just booted straight into the bootloader) Looked for the recovery option, selected....and nothing!!
So there isn't a stock recovery??? How does that work?
And what hope is there for this phone now? (I can't think of anything else )
Anyone have an idea? I've never heard of this before tbh!

Well, my problem has been sorted. In the absence of knowing what the hell I should do lol I managed to get a refund for the phone even though it was a refurb to begin with (something to be said for an honest seller who provides a 3 month warranty!) and I picked up a brand new N5x, which was unboxed on Tuesday. Not even 6 hours into setting it up, the phone started to get progressively hotter and then went into bootloop. Got into the bootloader and tried a factory reset - all seemed OK but halfway through the setup process it bootlooped again. Fortunately it was still within the 2 year warranty, and LG didn't argue about authorising a repair for a phone which didn't get even half a day's use on it lol
Authorised Wednesday, walked into the service centre Thursday and a 1 hour wait later had phone in hand with the PCB/motherboard replaced. Has been working fine (and cool!) ever since. Definitely feel lucky to have hopefully dodged a bullet on this one.
Bonus that they upgraded from 6.0 to 7.2.1 while they were at it; apparently LG considers nougat the "latest" stable version for the 5x.

need your thoughts on twrp recovery

hi all
im experiencing some weird situations on my razer phone.
flash magisk via recovery works how ever if i try to do a factory reset or backup my phone via recovery or even restore from that backup the phone refuses to boot, it gets stuck on the razer screen for about 2 mins before rebooting into download mode.
manually changing the active partition doesn't help and the only way to fix it is to re-flash the stock firmware.
bootloader is unlocked and i have ran the "fastboot unlock-critical" command as well
has anyone had the same or similar issue

Try to follow the root instructions again, making sure you flash stock multiple times in the process like it says to. Otherwise I don't know what happened.
