htc 820 stuck in recovery, cant boot to os. - Desire 820 Q&A, Help & Troubleshooting

hello I am trying to fix this old phone which keeps bootlooping. I can't get to the OS, and the bootloader won't show. When I try to go to the bootloader, I get to the recovery screen. I tried looking for an answer on google but all of the ones I found needed me to boot to the OS first. please link me to a tutorial for how to fix these, and explain like you would to a complete newbie. Thank you

This what you will flash the stock recovery of your phone since is booting into recovery. Now have in your sdcard the stock firmware renamed to whateva your line of desire is 0pjfimg etc. Now when your reboot your phone it will boot into the stock recovery there is an option for bootloader/hoot screen.The phone will see the firmware when it boot into bootloader. So and let me know ok.

Unable to boot Red Triangle

Hello All
So I wanted to root my AT&T HTC One M8
I followed instruction from androidcentral...
Now my phone will not boot up it keeps booting to TWRP in recovery only... when I boot to the system I get red triangle and exclamation point
After reading on xda they (androidcentral) had me flash my boot image instead of booting to it....
My phone is not booting at all any suggestions?
How can I get the original stock boot image for the AT&T?
I got the latest recovery image from Mr Hofs's post, but where can I get the boot image?
Also anyone has videos on how to root and s off the m8 not m7
Thanks!!!!
What do you see for sdcard size when you go to Twrp> install?
Nothing anymore...
I downloaded a backup from the thread collection of stock backup and flashed my boot and recovery and now the phone just sits at the HTC logo.
I am able to get to fastboot etc...
Does this mean I am missing the OS?
None of the backup has my CID on it so I don't want to backup from it.
Any suggestions?
Never mind. Went to the AT&T and found that someone made a backup
Going to use the backup copy and go from there
Thanks!

[Q] another person stuck with HTC splash screen

I have a Canadian HTC m9 , bootloader unlock, Twrp , rooted.
i was going to do a OTA to get the fix for the camera and heat issue. however on the process to revert back i end up stuck on the HTC splash screen with recover twrp acess .
what i did is did flash my backup file before the root and tried flashing stock recovery file. but no luck.
i tried flashing again the twrp and still no luck. and everytime i tried to reboot it shows NO OS installed.
any suggestion on what i can do to fix it? im kind new in HTC, i read upon the forum and not sure where to get RUU or the right ROM or if i should flash does stuff..... can i get some help?
I would suggest you flash the latest recovery through fastboot (2.8.6.4) from here https://basketbuild.com/devs/Captain_Throwback/One (M9)/Recovery and try to flash a custom rom or run an RUU if there is any for your variant

you solved the problem at the meantime?
if not.
push via adb a rom.zip to your sdcard and flash it via twrp recovery
yes it did fix it, i was able to boot the phone up again however, can i still flash my original back up so that i can get OTA? i tried using Venon ROM and according to them i can get the OTA but when i tried to update it no update available and i know there is one. i check my build # it still the old one, 1.32.401.17 CL506785 release key.
any idea?
thanks for your time.

How To Flash Custom Recovery for Androidone

So, I was attempting to root my phone(CanvasA1- 4GB) today running stock android marshmallow(6.0.1) , I successfully unlocked the boot loader in fastboot using adb, after which I flashed TWRP recovery, Which was successful but then, When I rebooted into recovery, I saw my old stock google's recovery running , I tried 2-3 more times flashing the recovery in fastboot but the probem was still the same :crying:. Then I came to know that we have to flash a special type of boot img of some 17.5mb approx, When I attempted to flash this "boot" image, I received an error saying file size too large, Hence I couldn't flash it, I am still running the stock recovery, With my bootloader unlocked, I need to root my phone, Please help someone, Thanks in advance .
http://forum.xda-developers.com/cro...-master-tool-unlock-bootloader-t2997696/page1 use this tool and flash custom recovery simple
You can search for Android One Toolkit. Iwas encountering the same problem but this app solved my Problem.
Sorry dont have Link for the Same.
Same here. I unlocked the bootloader successfully and flashed TWRP recovery. But it shows system/default recovery only. Now stuck in bootloop.
Tried clearing cache/date etc. nothing worked. Don't know what to do.

Semi-bricked XA1, possible recovery?

So my phone has been lagging a whole lot using the stock rom and I have decided that I'll try a custom rom to see if that changes anything. So I came here and saw this forum:
"https://forum.xda-developers.com/xa1/development/half-gsi-oreo-8-1-t3902259"
I thought I'll try and so I unlocked my bootloader, only to have my phone be reset (not a problem, everything was backed up). It also boots with a warning "Device unlocked and can't be trusted".
Then I went on to download TWRP using this link in that post: "https://mega.nz/#!FQFXCYSY!DgxQRkaY1Eqq3B0fZLEQBNzUs0Zj80L6IzSHxdorQ3A" which is the TWRP 3.3.0.0 V2 IS FOR ALL USERS.
I didn't want to flash in the event it was the wrong recovery so I tried booting into it, fastboot boot recovery.img
It flashed, everything was ok and now the phone doesn't boot. It stayed in a boot loop. I went ahead and flashed recovery this time, no luck. Downloaded a recovery.img from another website and it didn't allow me to boot to android or recovery.
Is there a way to save my phone, I can't get another phone until August due to contract. It can still boot to fastboot and gets stuck when trying to boot to android. It being able to boot to fastboot makes me think theres a chance to flash a stock rom or any custom recovery and rom to get the phone working again. Any help? Thanks!

OK use the boot.img and recovery.img made by @janjan HERE. Under the heading ¨Downloads¨ see ¨Xperia XA1¨ and download the KERNEL + RECOVERY the boot.img and recovery.img are compatible with the G3121-G3112-G3125-G3116-G3123 devices on the applicable firmware.
Flash BOTH using fastboot. The boot.img is patched to allow TWRP to boot which it will never do using the stock boot.
If you wish to go back to stock then simply use FlashTool to flash the stock fotakernel.sin and boot.sin contained in the firmware for your device.
Does it works becouse I boot my g3116 from flashtool camand was
Fastboot boot boot.img and then also it's stuck into bootloader

razer phone stuck in logo after install twrp any help please ??????

i have razer phone 2.
I installed twrp via fastboot then I got stuck on logo screen
now I can not go to recovery mode I can just go to fastboot and flash any rom
please i need help ????
er.. this actually needs to be in https://forum.xda-developers.com/razer-phone-2 (note -2) !
dunno for sure, but would think you can "fastboot flash boot <recovery_filename>.img"
Be sure to opt out of installing TWRP app, as that can cause bootlooping.
HTH
