Installing BusyBox + Root only (no CWM)?

Hi guys,
I need your advice related to rooting my Nexus phone I got from Google Play.
I will not install any custom ROM's, I simply need to spoof the carrier to T-Mobile, when I'm in Canada.
That said, I looked at few tutorials and from all of them, this one is mostly recommended:
http://forum.xda-developers.com/showthread.php?t=1529058
Before I proceed, I need your opinion about the tutorial and also if is possible to run on my phone just BusyBox, while rooted.
Thank you for your help.

To run root without CWM...
Simply uze the command "fastboot boot RECOVERYNAME.img" rather than the one in the guide.
This won't write a custom recovery to your phone...but boot into it one time only.

Thank you. I'll work on it and let you know guys how it went.

Everything went very smooth, no issues. Well the hardest part was to get the right ADB drivers, as I did not wanted to install unsigned drivers. I'm going to work now, will post the drivers info when I come back. For reference, I have now root without CWM.
If I decide to revert back to stock, what is procedure?
I have the bootloader locked now, so I guess opening it again will erase everything including the root files. Let me know please.
Edit: To get the drivers rolling in Windows 7 64bits Ultimate, I used this tutorial.

As long as you have root...
http://forum.xda-developers.com/showthread.php?p=27878074
Will unlock/lock without wiping.
And as far as returning to stock...you haven't modified much thus far.
So deleting busybox and then superuser will work...if you haven't modified any system files.
Or you could always flash the stock images (this does erase your "SDcard" and everything will be back to an-out-of-the-box state).

Exactly, its that easy.

I think I may have ruined my phone

Hey there
I want to start off by saying I have very little experience with rooting, but am very familiar with jailbreaking apple devices so I figured i could manage.
I have a htc one m8 on rogers network locked. I rooted it and had super user and all that jazz, then flashed AOKP. Then I thought i actually liked the stock HTC sense better, so I tried to "get things back to normal"...lol.
Now im at the point where if i turn my phone on it goes straight to the fastboot screen(?) with all the "fast boot, recovery, factory reset, etc". Since I'm super new to all of this is there anybody that can write some instructions on how to get my phone back to stock? I would really appreciate it after panicking over this for 3 days.
Edit: In the fastboot screen at the top it says ***Tampered*** ***Relocked*** ***security warning**
also when i try to press recovery it shows the htc screen for 1 second then back to the same menu
i found this http://forum.xda-developers.com/showthread.php?t=2710735 but i cannot even get into recovery

While being an expert with rooting and flashing custom recoveries on Samsung devices, I am also new to the world of HTC. Out of curiosity, what happens when you hit factory reset?

Unlock the boot loader again then install twrp recovery then head over to the stock backup thread and flash one of the nandroids for your cid.

Do fastboot devices ... adb commands itself won't work in bootloader, it has to be fastboot commands.

now you have a locked bootloader which means you cant do anything.. so your first step is to unlock it again then flash a custom recovery (TWRP) after that flash the stock rom+ boot.img ( to be safe) make sure it boots. RELOCK the bootloader then flash your firmware.zip.. hope it helps

If it's in bootloader it should show in command prompt when you type fastboot devices after connecting it to PC. If it doesn't then there is a driver problem perhaps. Check to make sure you have HTC drivers installed, or reinstall them. Might as well make sure adb is up to date as well, can do that through the Android SDK Manager. Another possibility might be that the usb cable isn't working correctly, try another cable. Fact of the matter though is, if it's in bootloader and you connect it to the PC adb/fastboot SHOULD pick it up.
So check and fix those things. Also make sure you use the correct commands, in bootloader mode, it'll be fastboot commands, not "adb devices" but "fastboot devices" ... "fastboot reboot" etc etc. Also make sure you're running the commands from within the adb/fastboot folder path(just for in case yeah...)

You didn't read any of my posts about that, did you? lol
I already stated adb commands like "adb devices" "adb reboot" etc will NOT work in bootloader, it'll work in the system and yes, it'll work in recovery for sideloading etc, but NOT in bootloader. For bootloader you HAVE to use fastboot commands, "fastboot devices" "fastboot reboot" "fastboot oem lock" "fastboot oem get_identifier_token" "fastboot flash unlocktoken Unlock_code.bin" etc etc

Sorry I skipped past your first response, that makes sense now.
So I need to put the rom on my internal storage then go into recovery and install the zip using TWRP..but when I plug my phone into the computer the internal storage wont show up.
I do have sync manager installed also, and it wont show up in that either

With that adb devices command again in bootloader? Did you flash TWRP yet? If so, Got to Advanced >>> ADB Sideload >>> Swipe to start sideload.
Place the ROM.zip file in your adb folder then:
Connect phone to PC, while still in recovery mode type adb devices to make sure your device gets picked up, should show you the serial number for device AS WELL as "sideload" next to it, if so then you are hooked up right. Next type adb sideload name_of_zip.zip wait until fully finished.
If sideload fails for one or other reason you can also try to push it. Reboot to recovery again, type adb devices to make sure device gets picked up, type adb push name_of_zip.zip /data/media/0/ or adb push name_of_zip.zip /sdcard/ flash as per usual then.
Yet somehow I don't think you even need to go to these steps

I made a small mistake with the sideload though, it actually installs automatically as such you don't have to go back into recovery to flash, as it did it already, sorry. Edited post to fix.
Well as long as you can get into phone now to copy the nandroid backup to the phone all should be in order, can flash back stock from the nandroid then.
Glad it worked out then.:good:

Hello BerndM14, thank you for this baby steps. Mine m8 is a gpe version, it's 4.4.2 google rom, rooted, cwm recovery, s-on. I was trying to flash the full google 4.4.3 zip rom under recovery, however, after that, my m8 automaticlly enter recovery everytime reboot. And I can manually enter the bootloader, my pc can find the m8 both in recovery and bootloader. I searched this post, and do it accordingly, I download the gpe stock backup KOT49H.H16 - 1.16.1700.16 - CWM Philz touch and use adb sideload gpe3.zip to the cell phone sucessfully, then the recovery automaticlly starts installing rom, then, I got below message:

Check for maximus or arhd (NOT the lollipop versions but a slight older one) in the dev section or get a new stock backup matching your version number in the general section - collection of firmwares, stock backups and more by @exocetdj
And if that doesn't give you the correct steps and files than try the specific Sprint M8 support subforum

Is it the normal sign ?

Yes as you are s-on that's normal. Only with s-off you can change those flags to LOCKED

After that I type reboot ruu and after 1sec reboots back to bootloader. And in bootloader I choose download mode a messages appears saying unable press any key to return. I only have access to recover and. Bootloader. If I wanna flash mm how can I do it.or how can I fix it.

If you have root and S-OFF with TWRP/CWM you might be able to manually overwrite the aboot/bootloader partitions. Either from recovery or from an adb shell. I not completely sure what exactly is going on, but seeing as the last thing you did was flash a modified firmware.zip. Maybe something got screwed up.

Yesss!!!!! Thank you. Show me how please. And yes s-off
Enviado desde mi HTC One M9 mediante Tapatalk

Are you S-OFF?

Have you tried going straight into download mode? Phone off Press volume down and power. If that works you can save the firmware zip in your sdcard renaming it 0PJAIMG and attempt flashing it that way. This other method may or may not work on your phone if you aren't Unlocked or S-OFF. It's a complete stock firmware without the ROM so itll replace your recovery and kernel.
You also run the risk of completely messing up your phone. So do it at your own expense not mine.
Anyway this idea is basically you manually rewriting your aboot with a stock one. Make sure you have adb and htc drivers installed, I'm assuming you are rooted.
Copy aboot_signed.img to your sdcard
From a terminal in TWRP or from a command prompt in windows (use adb shell) do the following commands
cat /proc/emmc - This will give you a list of all the partitions on your phone. Among all the ones you'll see your bootloader
mmcblk0p13: 00100000 00000200 "aboot" -- It should be the same on yours. If its different let me know before you do the next command.
dd if=/sdcard2/aboot_signed.img of=/dev/block/mmcblk0p13 - This will flash the stock bootloader that's saved on your sdcard. When you run the command you'll see some thing about bytes in bytes out so on and so forth. Aslong as you don't get errors or failures then you are good. Reboot the phone see if you can go into download mode.
If that doesn't work then it means something else is causing this.

[SOLUTION] No IMEI / Signal after downgrade Oreo 8.0 to Nougat 7.0

I found a post explain how to get IMEI back.
original post: http://bbs.gfan.com/android-9272781-1-1.html
Two methods for S-ON or S-OFF device, please do it under Nougat 7.0 firmware installed.
S-ON
1. Reboot to TWRP recovery
2. Use the command below to erase persist partition
Code:
adb shell
dd if=/dev/zero of=/dev/block/bootdevice/by-name/persist
S-OFF only
1. Reboot to bootloader (not download)
2. Use the command below to erase persist partition
Code:
fastboot erase persist
Is that possible to downgrade without S-OFF??
Please watch my video, HTC 10 can downgrade in the same method!!!
PS. This video is for HTC One M9, please use Nougat RUU/firmware for HTC 10 to do downgrading.

Two methods for S-ON or S-OFF device, please do it under Nougat 7.0 firmware installed.
S-ON
1. Reboot to TWRP recovery
2. Use the command below to erase persist partition
Code:
adb shell
dd if=/dev/zero of=/dev/block/bootdevice/by-name/persist
S-OFF only
1. Reboot to bootloader (not download)
2. Use the command below to erase persist partition
Code:
fastboot erase persist

Probably for people who didn't update firmware. Ie flashed leedroid ROM without Oreo firmware first.

Anyone explain S-ON Oreo to Nougat Downgrade instructions ? Please.

With a RUU you cannot downgrade while you are S-ON.
Try maybe will work if you flash a Nougat Rom with TWRP and you do the command for S-on in TWRP to erase the persist partition.

It's for people who didn't update firmware. Just S OFF your phone and be done with it
