[Q] failure after root and tried to recovery

Hi there I have a Nexus S with 4.04 on it, so the other day I followed the instruction online and tried to root the phone, I have phone driver installed, and able to unlock my bootloader, the LOCK STATE is UNLOCKED. and I was able to flash Clockworkmod recovery v5.0.2.0.
But after this step, and I tried to reboot, my phone just stuck at the google logo with the unlock sign at the bottom, and wouldn't do anything afterward. (seems like a root loop?)
I tried pulling off the batt a few times but no good. I am still able to lock and unlock bootloader through cmd.(just like in normal state)
I tried to install factory img as shown in the thread http://forum.xda-developers.com/showthread.php?t=1572307. but when I type in the first line "adb reboot bootloader", it says adb devices not found.
so, any idea on how I can restore back to the factory img?
bootloader version i9020xxkl1
model GT-i9020T or if any more info is needed I will be here.....>.<

Did you correctly installed the recovery?
Hi.
First at all let me tell you that I'm not an expert. So, I understand that you should double check this.
I think that you should try to:
- If you have successfully installed the ClockworkMod recovery, you should turn on the device on recovery mode. Vol up + on pushbutton to go inside bootloader. Going down with Vol down, go to recovery and select with on pushbutton.
- Download the correct superuser app for your version. I would double check the md5sum of the file that you have downloaded on your computer.
- Mounting the usb storage of the device on your computer, add the superuser app on /sdcard.
- Umount the usb storage.
- Flash the superuser app, installing from /sdcard from your recovery menu.
- Download a custom kernel on your computer, once that you are unlocked. I'm using CyberGR, and I'm happy with it. You can see all the intallation instructions in the Nexus S development part.
- I that works, I would try to install the kernel in a clear way. For installing the CyberGR ROM, you need to wipe everything and format all. After that, you mount the device on the computer, and try the installation.
Then, if everything is ok, the device will turn on.
Again, I'm not an expert, and I don't know how you can be in contact with the developers that are posting in the developers area. I'm not responsible if your device doesn't works or get bricked.
However, I understand that all that I have described, should not put your device in a worst situation.
And is it doesn't turn on, if it doesn't do anything, then, you can use the linux tooll for bicked devices explained on the developers area.

[Q] Stuck in bootloop, recover files

Hello.
Today my oneplus one was suddenly stuck in bootloop. This happened in the middle of the day when I rebooted my phone. My phone was running the latest update that came OTA (stock lollipop). Whenever I boot my phone it starts loading and suddenly a Chrome (browser) window appears for 1 second and tries to load a website. Afterwards my lock screen pop ups for 1 seconds and it starts to reboot. During the lockscreen I tried to unlock my phone as soon as possible, but it just reboots. (Any ideas about this weird problem?)
I CAN boot it in recovery mode by holding volume-down button and power button.
I CAN boot it in fastboot mode by holding volume-up button and power button.
Perhaps a factory reset will do the trick, but I don't have a backup of my files (because this happened so suddenly without me trying to flash/customize my phone). My first priority is recovering my files, because most solutions will end up in me losing every file. Unfortunately I've found little possibility to do this during the bootloop problem. I've tried to flash TWRP because it could make backups of my phone. I tried it through ADB/Fastboot, but it failed because my device is not unlocked (I can't go to settings and put my phone in developer mode and debugging mode). So I've read somewhere that unlocking my phone (bootloader?) through ADB will wipe my phone, which is exactly what I don't want.
Also I've tried this: http://forum.xda-developers.com/oneplus-one/help/fix-brickloop-audio-fx-fc-efs-corrupt-t2879061
But It also failed because my device was not unlocked.
Did I miss some steps somewhere or did I read something wrong?
Hopefully anybody has an idea to either fix the bootloop without losing my data, or finding a way to recover my files before wiping the phone.
Thank you.

Unfortunately you might be stuck in a catch-22 situation here. In order to access the files you'd need to unlock the bootloader, but in doing so you'd lose those files. Without usb debugging already enabled I can't see a way out of this.

Decided to unlock the bootloader through ADB. (bye bye data)
After I've unlocked it, I've tried installing TWRP.
Some minor problems occured but I can finally boot into TWRP through volume-down button + power button.
I've decided to download the stock ROM i've found on the OPO forums.
Couldn't acces my phone through normal methods, so I had to use ADB to push the files into my phone.
Installing the file through TWRP, wiped cache/dalvik and installed super user before rebooting.
After rebooting my phone is stuck on the boot screen now. (This also happened before I installed TWRP on my phone)
I've also tried this method: http://forum.xda-developers.com/oneplus-one/general/guide-return-opo-to-100-stock-t2826541
Also no succes. I'm stuck in the bootscreen where it says 'cyanogen'.
EDIT: Managed to fix it eventually through: http://forum.xda-developers.com/oneplus-one/help/fix-brickloop-audio-fx-fc-efs-corrupt-t2879061 (part 2) writing the command in TWRP.
Phone finally boots normally again.

Exactly what did you flash? Full filename please. No errors occurred?

Hopefully the stock cyanogen OS.
First I've tried to flash cyanogenmod 12 through TWRP (file is found here: https://forums.oneplus.net/threads/cm12s-yng1tas17l-installation-guide-review-change-log.304615/)
Afterwards I was still stuck in bootscreen, so I've looked for another solution.
Which made me find this guide: http://forum.xda-developers.com/oneplus-one/general/guide-return-opo-to-100-stock-t2826541
After flashing this file (probably the same thing) the problem still remained.
Eventually after multiple wipes/factory resets (which did not solve the problem) I've entered the command in TWRP and after reboot it finally worked again.
So I basically flashed my phone twice, once through TWRPS and the other through the batch file (perhaps ADB?).
Also no errors occured which stopped the flashing and commands. Did have to reinstall TWRP and reboot instantly in it by holding the volume down button multiple times. This doesnt happen anymore though.
Only had to install google apps for CM12 (gapps), for which I used TWRP in recovery mode.
Currently reinstalling most apps on my phone and no problems yet.

After rooting my nexus 5 is not booting up with non stop booting animation

I have a nexus 5 16 GB and i downloaded the recent software update android 6.0.1 and then I decided to root and I used 'Nexus root toolkit v2.06' and first unlocked the bootloader and then rooted. Everything worked fine but after the process was complete it was rebooting and the booting animation went on and on for many hours and the device did not root. I really don't know what's going on. My purpose is to install a custom rom: cyanogenmod 12. Now what should I do ???? PLEASE HELP. When i try to enter recovery mode it shows a picture of the android mascot with opened back and exclamation and cannot enter command as well. and after some time the booting animation begins and goes on and on...
please help...

Unless something has changed, version 6. requires that you flash a special kernel before you can root your phone otherwise you are as you are now, stuck in a boot loop. You should probably download the factory image from Google, and then flash the system image to get rid of what you have done.. Perhaps then your phone will start normally

Thank you very much for the reply, I really do have no idea as to how to flash the factory image because i am very new in this area. Could you please recommend software and which factory image i should download, please ?? thanks very much.

Also, you mentioned a 'special kernel' what does that mean. All i want to do to my device is install cyanogenmod 12 and for that i believe it needs to be rooted, so i am really confused. What should I do know

I'm having this same problem, and unfortunately, when I start the phone on fastboot, I can not access the recovery mode in order to upload a factory image of nexus 5.
I used the new tool available her for quick flash, and now, I don't have a phone.

First, don't panic. Your phone is still very easy to recover. Unfortunately I can't get you a complete walkthrough here (for now at least), so I'll give you the main idea and you'll have to do your homework (as maybe you should have done before).
1. You need to get fastboot working on your computer. It's included in the Android sdk package, but there might be some easier way to get it. Google it. You might need drivers for your pc too. Google it as well.
2. Then you need to get into fastboot mode on your phone. To do it, hold down power button AND volume down button until it gets into fastboot mode. You will see an android on his back with the cover open. At this point, connect your phone to your pc, open a terminal on your pc and type "fastboot devices" without the quotes "". It should find your phone if fastboot is working. If it doesn't work go back to step 1.
3. Download TWRP recovery on your pc and place the img file in the same folder as your fastboot executable (not mandatory but easier). It can be found here https://dl.twrp.me/hammerhead/
4. Always in fastboot mode, type "fastboot flash recovery twrp-2.8.7.1-hammerhead.img" assuming you downloaded that file, which you should have by the way. It should install fine. If you haven't placed the file in the same directory as your fastboot executable, you will need to provide the path to your img file as well.
5. Then use the volume rocker to switch between modes and choose reboot recovery.
6. You should now be in TWRP recovery. At this point, download a custom kernel (anyone found on xda for hammerhead should do) and push it to your phone. It should be fairly simple with TWRP. Then flash your new kernel using install. It should help you get your phone booting normally. Alternatively, you can download a custom ROM like cm12.1 and flash it altogether. It will install everything needed for your phone to boot up too. Beware if flashing a ROM though, I strongly advice you to do a factory reset before flashing it. You will find that option in the wipe menu.
Hope it helps, let me know if you need further assistance.

Yesterday, I have tried everything to have my computer to recognize the "fastboot" command, and I installed like 2 or 3 different programs for that. With my old Windows 7, I have been able to push a flashed image to fix this issue, using the fastboot command, but with Windows 10, it's always telling me it's not a valid command. I'll keep trying it, otherwise, i'll have to "resurrect" my old Windows XP computer.
Also, I noticed now that, while trying to install the fastboot, as per some files that I could download, but no file has been copied into my computer, not even if I run it as admin.

fixed. but no RECOVERY mode options....
Hi Guys,
Thank you very much for the help, I have finally recovered the phone and running android 6.0 MRA58N but it is not rooted. Now if you don't mind could you teach me how to root because i have checked lots of videos and tuts but none worked for me...
IMPORTANT:
when i am in recovery mode why cannot I access options even when i press volume up + power button and release them at the same time...????
Thanks in advance.

Just flash a custom recovery via fastboot. Just make sure your bootloader is unlocked. Can't link though.

hi guys i have used nexus 5 mobile with cyanogenmod 14.1 .It worked properly in 1 year. after that suddenly switched off and it not properly boot up .i try to switch on my mobile , first it show google with unlock logo properly and when it show cyanogenmod logo it stuck and again show google with unlock logo....i try recovery mode to wipe and flash the same rom ....the process is interrupt at middle stage and again show the google..i try lots of time . after few try that process finished completely without interrupt. then use my mobile 1 day same as i used first time root. after that same problem occur on my mobile ..so help me guys

Honor 6x - Bootloader Unlocked, now won't boot into ROM or fastboot

Edit & Update: I tried all method's, unable to boot into bootloader, or access the recovery, eRecovery & the dload (to force update) I took it to the service centre and got the firmware flashed from them. If this happens to you, take it to a service centre.

Don't worry, you still have a chance and it is using the dload method. For doing that, the only thing that you need is your firmware package, then there's a keys combination (vol up+vol down+power) that if pressed on a phone that is off, gives the input to flash what is in the dload folder. Begin to recover your firmware package, then I'll be here for any help.

that would be difficult, I cant get into the erecovery or the recovery mode. i am worried the device is bricked. also can the fastboot mode be corrupted?

Surely something went really bad, looks like some partition is messed up if neither fastboot mode is accessible... But for doing the dload method you won't need fastboot not recoveries, you just have to press the 3 keys on phone while is off to let the flashing process begin. But for doing this you'd need to obtain the UPDATE.APP extracted from your actual firmware package, and place it on your phone's memory or external SD card in a folder called "dload". Connecting the phone to the PC gives some results, of any kind?

yes something did go reallly bad, i stil dont know what that was. But for the 3 keys method to work, shouldnt the force update thing be accessible? atleast it will show some option, to force update, ayt I will try that method. Connecting the phone to the PC while in blackscreen yields no results. ADB or FASTBOOT cant detect it either.
my current firmware is BLN-L21C185B371
using firmware finder on PC, I have found 3 files to download which are;
1: update.zip
2. update_data_public.zip
3. update_BLN-L21_hw_meafnaf.zip
Which of these should I download?

theres been an update to the situation:
the phone died ( Battery depleted ) and so after I plugged it in, it rebooted to the ROM, and now it is working, but I am still unsure whether the next time i try rebooting whether it will work or not

Hello, I had the same problem, so it cannot be just something went wrong case. I have a BLN-L24 model, EMUI updated to 5.0 amd Android 7.0 online before unlocking the bootrom. I was able to exit the boot screen pressing the 3 buttons as suggested and I got the error of missing files, but after the reboot it goes back to the ROM. I tried again to copy berlin.img file for TWRP but same problem. So either I give up on TWRP or keep trying doing more research. To be on the safe side (in case it works) could anybody provide me with the original img file for this phone?

I am unable to exit the warning sign. if I power it off, it auto boots into the warningit boots into the ROM when the power is depleted, but if I try to restart or anything else, it shows the warning screen only until power is drained.

I am confused, I thought you were able to boot to the ROM after your battery died. The warning sign will be always there, the problem is only when you force the recovery mode, the TWRP image doesn't load.

it boots into the ROM only after the battery has drained off all the power. then after that when I charge and try to boot into recovery or fastboot it shows this: https://i.imgur.com/FpcxllE.jpg

"Type password to decrypt storage" Honor 8

Hi.
Last year I tried to root my Honor 8... i failed. I've managed to unlock it but i did not root it (idk why, i just followed a tutorial but nothing happens as it should).
My phone was JUST unlocked. Not rooted. I just had this beautiful message when I boot it "Your device has been unlocked and can't be trusted. Visit blablabla......."
So I wanted to recover it... but i couldn't, using android or the huawei recovery thing.
So I decided to follow some tutorials (big mistake, i know nothing about this world). I tried to flash the stock rom...
I downloaded "Huawei Multi Tool by MT" and I "flashed stock eRecovery images from an online database" (choosing a randon version)
It worked but now, I have this message "Type password to decrypt storage" every time I boot my phone. I already tried to take out my SD card, to reset factory from the recovery (did it many times)... nothing works.
I can try every password, it says that "the password is correct but data is corrupt so you have to reset" ......................
im afraid of losing my phone right now
I had FRD-L09C432B394
Android Nougat
EMUI 5.1
If you could please help me or send me a link, because i tried several tutorials but ... none correspond to my situation, my version etc.
Thanks !!

Best thing I can think of to do off the top of my head is flash twrp and flash magisk. Then install titanium backup to backup all your apps. It is going to require you to read and learn a bit, but not doing so is what put you in this spot to begin with.

Ok but... How? I think I can't access to bootloader. I can only access to this HUAWEI recovery thing if i press power for a long a time, and if i don't, it asks the password..
Something to do with my pc with USB connected?
btw i dont need to "backup my apps"... i dont mind if i lose all my data. i want it.

Yes, holding down Volume Down while your device is connected to PC will boot it to Fastboot mode. Flash TWRP (search this forum for the link) and the inatall the same FRD-L09C432B394 firmware files (update.zip and the rest) through TWRP. Once done, reboot your device to recovery (this time it will boot to stock recovery) and perform a full factory reset.

I just had the same issue, I rebooted in recovery mode by pressing "volume up" and the built in recovery told me the partition was corrupted and asked if I wanted to format it
