[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] TF300TG Boot/Recovery Problem

OK - some help please? I've replaced/unlocked bootloaders and installed cwm/twrp/custom roms and recovery on a dozen android phones and tablets recently - but the TF300TG has beaten me ....
I have recently:
1. Unlocked bootloader on 4.1.1 device using Asus Unlocker v7 (OK - so there goes any warranty )
2. Upgraded to Android v4.2.1
3. Installed JB TWRP - android remains accessible and functional but cannot access partitions from TWRP
4. Replaced TWRP with CWM (recovery-jb) - no improvement
5. Returned to TWRP. However on reboot, the system immediately boots TWRP instead of full android. I am unable to access either Android proper or Fastboot.????
EDIT: I should also add here that I suspect it was some idiot's(umm - that'll be me) foolish Wipe within the TWRP at step 5 above that caused this disaster - and that this removed more than just data. RTFM Richard!!
Not bad for a 4 day old tablet eh? Since I can no longer access fastboot, my guess is that I may need to rebuild the partitions (or at least the partition table) via ADB Sideload. Make any sense? If so, a little guidance really would be appreciated!
TIA,
Richard

Bump?

Once booted in TWRP go to the Reboot menu and "Power Off" then boot into fastboot (it should NOT skip straight into TWRP unless your volume rocker is busted). Once you've got fastboot back ensure you do get the right TWRP!
f69m said:
First of all go to the bootloader screen by holding power and vol-down.
Double-check the Asus version of your bootloader at the top of the bootloader screen and pick the right TWRP version for it:
For Asus v10.4.*: any TWRP *-jb.blob
For Asus v10.6.1.8.*: only TWRP 2.4.4.0-4.2.blob
For Asus v10.6.1.15.*: any TWRP *-4.2.blob
Hope this is clear enough!

Thanks for your suggestion Rhian. However I've not yet sorted this. Perhaps a little more info from me will help you help me
The device is running 'Android cardhu-user bootloader <1.0.0 e> released by "WW_epad-10.6.2.3-20130402" A03'. It was unlocked with Asus Unlock_v7 whilst still running ICS and has had Superuser-3.2-RC3-arm-signed.zip installed.
Currently, on initial power up, the device boots straight into TWRP v2.5.0.0 Recovery. I can execute TWRP commands - however there seems to be an issue with access to partitions. Although I can mount the System partition - Cache & Data as well as Micro SDcard and SD-Ext are unmountable (neither can I see block devices in /dev that relate to these). I am however able to access a shell via adb. Further, both volume toggles appear to be operating as they should.
Rebooting from TWRP alerts that "Root permissions appear to be lost". I have attempted to reinstall Superuser but this has not resolved the matter.
"adb reboot boot-loader" will reboot the device into fastboot mode with the boot screen noting "Key driver not found .. Booting OS" and the version info above. From here, I have attempted to use adb to replace TWRP 2.5.0.0 with version 2.4.4.0. Although the adb commands complete without error, the new recovery is not written and the existing 2.5.0.0 remains in place.
From the Fastboot screen on the device, it can be forced to boot Android where everything seems to operate normally and with all partitions and filesystems appearing to be accessible.
All this suggests to me that there is either a problem with the bootloader itself, or less probably, that there is an issue with one or more of the partitions which is interfering with the boot process. There is however a better than even chance that I'm wrong.
I'm considering reformating and replacing the partitions one by one - however this seems rather extreme and in any case, I've not been able to locate an ASUS source of the partitions images yet.
Doing my head in here Rhian - any suggestions?
Thanks,
Richard

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...

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

@[email protected], possible power button problem?

Huawei Mate 8 (NXT-L29) won't boot into recovery.

Hey folks,
I've tried a few tipps others gave me here on xda, but nothing could fix my problem.
My situation looks like this:
I've been playing around w/ some TWRP versions and Custom ROMs,
and out of sudden my phone got soft bricked (stuck at the »Your phone is unlocked and can't be trusted« screen).
I was able to bring it back to life, via the Italian Knife and official stock ROM.
So, now I'm back at stock (NXT-L29C432B320) but my bootloader is still unlocked.
And it doesn't matter which TWRP version I flash, my phone won't boot into recovery,
so I'm not able to flash a Custom ROM.
If I try to enter the recovery mode it get stuck on »Your phone is booting now...« ... doesn't matter how long I wait, it won't boot.
If I flash a stock recovery, I can enter the Huawei eRecovery, but that doesn't help much.
Someone told me I have to lock my bootloader again to start the whole unlock / root stuff from scratch,
but if I try to lock it via fastboot it always fails w/ the »command not allowed« message.
The developer options & USB Debugging options are enabled and the Enable OEM unlock option, too.
Is there anything I can do or am I screwed?!
Btw, dload is not possible, 'cause the phone freezes if I try to do it from the dialer menu
and if I try to do it via the button combo, the phone just enters the Huawei eRecovery.

Do a dload of your region firmware
This should solve your problem

Put Update.app on SD card in dload directory.... use the latest firmware for your phone region or last used stock firmware.
Install SD card.
Power off.
3 button startup will install firmware on your phone and your phone will be stock and locked.
If you get :not compatible story you must adb and fastboot cust files using @somboons tools.

i had read your problems
it same as my problem so i flash with Decrypted & Insecure boot.img with adb fix via adb truely version 320or ver.......

after thats reboot if can not reboot must dload agains

Wileyfox Spark X

Hi all,
This is not the right forum, but I didn't see one specifically for Spark X models, so I'm sorry.
A friend of mine has a Wileyfox Spark X device, which was bootloader unlocked, had TWRP 3.0.2 installed and was running on the original firmware (6.0.1) but rooted and xposed installed.
Now an update came out for Android 7. To update the device, I put back the original firmware and recovery, started doing the upgrades and all went smooth.
Device is up and running on Android 7, however when I now try to install TWRP again, it won't work.
(fastboot flash the TWRP recovery (same version as before - 3.0.2) seems to work ok. I then go to pull the battery after flashing, put battery back, and start recovery by pressing vol down and power.
I see the device going to a black screen, then reboot and keeps doing this as long as I keep the vol down pressed. Once I release the device continues normal boot and goes into Android.
I assume this has to do with a change in Android 7?
Seems I can get TWRP working again, if I flash the original boot image, however then ofcourse the Android boot doesn't work anymore. (additionally once in TWRP, it seems /system cannot be mounted anymore and TWRP thinks no system is installed)
So in short, I believe I should get a newer TWRP version that is compatible with Android 7. I tried the different versions available on twrp.me (up to 3.1.1.0) however to no avail. None works with the latest android.
As such, the device is able to run in android 7, but without root. (no adb root option in developer options, adb root doesn't work either, kingroot etc also no go)
Does anyone have any options that I can still try? or could help me with a proper TWRP version that should work? (I did find some TWRP recoveries on 4pda (russian website) for Spark + that claim to be for Android 7, but those didn't work either))
Thanks !

@Asansi
I'm sorry I can't help you, but may I ask how you rooted the phone? I can't get mine to be properly rooted.

I can help you with any problem. I'm a senior person in that model since I have been using it ever since. If you could like

Apologies for ressurecring a zombie thread but, OP has a spark X and you have a Spark, so it would appear that you SENIOR person in that model failed at the very first hurdle.
Am still wonderng if there is an sign of a 7.0 compatible twrp for spark X? Don't suppose anyone has a link to the latest Spark X firmware either?

I've tried TWRP 3.0.2-0 (i.e. latest from https://dl.twrp.me/porridgek3/): it flashes Ok but it won't boot up afterwards. I've tried 3.0.2-0 but as you say "it seems /system cannot be mounted anymore and TWRP thinks no system is installed)". After letting it finish, Root Checker (not unsurprisingly) says that device is not rooted. Have you progressed with this issue? BTW I've emailed TWRP Support (from their web page) asking if they have a working version.

Same problem here, It's pretty annoying. My sister's getting this same phone (on Android 6) soon so I might just make a full backup with TWRP on it and somehow restore it on my phone.

Systemless Root
I can't decide whether to try the rooting method given in https://android.stackexchange.com/questions/160130/how-do-i-install-systemless-supersu-in-samsung
The method is:
Sometimes the need for a systemless installation of SuperSU is not detected by the installation script, to force this to occur follow the following steps.
Start TWRP 3.0 or higher on the device
Go to Advanced - Terminal
In the terminal, enter echo SYSTEMLESS=true>>/data/.supersu
Press Enter
Exit to the TWRP main menu
Flash the current SuperSU as per normal
When flashing SuperSU, you should see in the TWRP recovery log screen mentions of system-less installation and patching of the boot image.
Has anyone had experience of this method?

Resurrection! This post shall LIIIIVE!
No, seriously tho, does anyone have any updates on the issue? Or could at least point me in the right direction to root a Wileyfox Spark X? At this point, any help is much appreciated, since I have not been able to get ANY method working for me.
Thanks a lot

I am afraid not, since I can't install TWRP. One info would help me out a lot tho: would an Android-Downgrade (from 7.0 to CM13) help with installing TWRP and rooting?
Steps taken earlier:
quite literally everything (that would make sense even remotely)
Steps taken today:
- Downloading TWRP 3.2.1-0 (https://twrp.me/wileyfox/wileyfoxsparkx.html)
- fastboot-unlocking the bootloader (no issues)
- trying to install TWRP (no issues there either)
- when trying to reboot straight to recovery, I don't get past the bootlogo, suggesting to me that either the install or TWRP was corrupted.
Any help one might get?
Thanks a lot?

The only version that I had success with was 3.0.2 from https://dl.twrp.me/porridgek3/"]https://dl.twrp.me/porridgek3/[/URL]
Even then, It's all hit & miss getting into TWRP:
1. If I do anything after flashing (e.g. booting as normal), I have to go into fastboot & flash TWRP again.
2. Once I have flashed TWRP (i.e. still in fastboot mode), I can't leave fastboot mode. Also, the phone will not switch off unless I remove the battery and put it back in after approx 10 seconds.
3. Even then it often refuses to load TWRP i.e. it goes into the Android Boot menu.
AlwaysLivid suggested that you can boot to TWRP by executing "fastboot boot recovery.img" (where recovery.img is the TWRP img file renamed) on MSDOS Prompt / Terminal according to whether you're using Windows or a Linux distro (e.g. Ubuntu which I use). Presumably this would be after you have taken the battery out for a few seconds before inserting it again and have then booted into the appropriate mode with the Volume Down & Power buttons held down.

Thanks a lot, I'll try your method, the explicit call to boot the TWRP image could really help.

Finally, your advice with "Fastboot boot twrp.img" worked magic!
Got twrp installed, but now I'm facing the same problem as you with the systemless root. I'll dig around a little and see what I can find.
