[Q] GNex on Stock ICS 4.03; can't root or flash

Hey guys i bought a GNex off a Google employee and the phone came stock with 4.03. I've already unlocked the bootloader but can't get the phone rooted or flash with a different rom. I've even tried to upgrade to 4.04 that was just released but it will not let me upgrade.
Is there a way i can flash to 4.02? any help will be greatly appreciated

Have you rooted and installed CWM Recovery?

cannot root the phone, i've tried and phone just hangs

Have you downloaded the gnex toolkit in the development thread and tried that?
Sent from my Galaxy Nexus using xda premium

tried the wugfresh and the gnex toolkit 5.2; wont let me root 4.03

Have you installed a custom recovery?

which custom recovery? cwm recovery will not work without root access correct?

you can not have cwm recovery without root. do u have a GSM or LTE GN?

LTE version
I cant seem to find a way to root 4.0.3

Incorrect.
Root access gives you write access to the OS, which is separate from recovery. The standard root method for a Nexus device is to remove security from the bootloader, which then allows you to install non-signed images. You then install a custom recovery image. The custom recovery allows you to flash non-signed OS changes, which means you can flash the su binary and busybox (giving you root)...
You need to use fastboot to flash cwm, then you can install su and busybox...

ok gotcha, i was under the stupid assumption that i needed to gain root access to install a custom recovery. im going to give it a shot and see what happens

If you want to install recovery from the OS, then you would need an insecure/rooted OS. If you want to install recovery from the bootloader, then you would need an insecure/unlocked bootloader...

thanks so much, got recovery on there and updated the phone and rooted it as well. appreciate the help

Same here
Same thing happened to me. I installed the Gnex toolkit and unlocked the bootloader. Then I tried to root the phone: It restarted and I turned on USB debugging as it said and nothing happened.
So you're saying that I can skip the rooting and "Rename Recovery Restore File" before I "Flash CWM Recovery". After that I can try rooting through Gnex Toolkit 5.2?

Cant Root Galaxy Nexus

Hey guys
Before 4.2 (and thus, 4.2.1) release, I had my 4.1.2 Jelly Bean Galaxy Nexus (TAKJU) rooted and it felt really nice, with programable underclocking to save battery and stuff. Now on 4.2.1 Jelly Bean, I cant root it using the same method I used back on 4.1.2 (I used GNexus Toolkit V9.1 and Now I'm trying with GNexus Toolkit V10.1)
What can I do to root it?
Thanks!

dont use toolkits, do it the right way. fastboot oem unlock(if your bootloader is locked), fastboot flash a custom recovery, flash either the su binaries or a custom rom in your custom recovery, reboot and profit.

I have bootloader unlocked. I'm new to flashing and stuff, how exactly do I do all that stuff? I (theoretically) have SuperSU installed. Back on my 4.1.2 root I had clockwork mod recovery, is it lost?

Theoretically? Either it's installed or it isn't. Check your installed apps list for SuperSU. Open a terminal window or file explorer and look for the su binary.

Reflash supersu zip (refered by 3rdstring) in cwm again, you no longer have the correct su binary, which supersu and any other app that requires root need.

[Q] Flash bootics.img on Xperia Play

Start by saying I'm very new about Android and smartphone in general.
Four days ago I got my first smartphone, a Xperia Play model R800i and some friends suggested me to install ICS. I searched on the internet and I have found the Xperia Play Development forum. There, I found a really interesting ROM called "New Express ICS".
I downloaded all the files and I started to follow the guide. I'm stuck at the second point (I believe this is ridiculous): I can't get into the Recovery Mode and I didn't get if I can flash the custom kernel (bootics.img) on flash tool.
I haven't rooted my phone, it's 100% virgin, yet.
Can someone explain me what to do? I'm searching answer here and on google for three days and I'm getting even more confused.
Sorry if my english is not perfect, it isn't my first language.

You need to unlock bootloader before fastboot a kernel (bootics.img)

Thanks for the link, it's very useful! Just a question: what do you mean with "read the root"? I have to root the phone?

I rooted my phone and I found the superuser app on this. Then, I unlocked the bootloader and the superuser app disappered, is it normal?
One more thing, how I flash the custom kernel and the ROM, now?
EDIT: Fail, Superuser is installed, yet, I didn't notice that
EDIT2: Why I can't get into the recovery mode?

I see you unlock your bootloader, good job! Place the ROM zip into your SD card first. Next, to get into recovery mode, just fastboot the kernel you want.
-Power off phone.
-Hold search button while connecting to PC via USB
-Open flashtool, click the thunderbolt icon, select fastboot
-Select kernel to flash (select your kernel bootics.img)
-Wait for 2 seconds and voila!
After that, power on your phone, when blue LED lights up with a vibration, spam volume button / back button (depends on kernel) then you'll be able to enter recovery

Again, read his guide on flashing kernel and roms: http://forum.xda-developers.com/showthread.php?t=2054512
Which kernel you flash is depended on the rom you want to use it with, you need to flash a GB kernel if you want to use GB rom, ICS kernel for ICS, etc, although some kernel are compatible with both ICS and JB. Search the development section for kernels and roms. If you flash a rom and it fail to boot, it mean the kernel currently installed is not compatible with that rom.
About ClockworkMod Recovery:
If you flash a custom kernel, it will likely have ClockworkMod Recovery included. Or if you are using stock Sony firmware, use the "CWM installer version 5" from this link to install CWM. Sometimes you will get a status 7 error when you try flashing a rom, it might mean you have to use a different version of ClockworkMod to flash that rom successfully.

First of all, thank you both!
Can I flash bootics.img in the Flashtool? The fma965's tutorial speaks about a "*.zip" file besides a "*.img" file.
Also, he says to use fastboot package that I have already used to unlock the bootloader.
EDIT: I need Busybox? What is it? I didn't get it.

Flash boot.img in Flashtool/Fastboot as instructions above from jeff7424:good:Zip files are what you put on your sd card and flash with cwm recovery, these can be either roms, updates to roms,zip files to change appearance, performance tweaks, too many to mention.
So .img and .ftf files use in Flashtool/Fastboot and zip files use on SD card to flash with CWM recovery.
Not to complicate it too much sometimes the boot.img comes in a .zip file you need to extract this to use in flashtool/fastboot with winra/7z unzip programs
Edit; Busybox download it with Superuser app on your phone or download a app from store to update your busybox
What is it?http://en.wikipedia.org/wiki/BusyBox

But I don't need busybox to flash kernel and ROM, right?

You can get busybox from Play Store, just search Busybox installer, install it, open the app and install busybox.

Yeah select kernel to flash. Nope you just need an unlocked bootloader.

But I'm a bit disappointed because Crash Bandicoot disappered...
Thanks everyone, by the way.
For the future update, the phone will format again?

root issue with Z1c

Hi guys, i just bought Z1 compact and i want to make a root. Is it possible to root the phone with EasyRootTool if i have option bootloader unlock allowed set to NO?

You can use newroot or towelroot or other method
You can have a root without unlocking bootloader. Bootloader unlocking is other thing. If you have unlocked bootloader you can flash custom kernels

You are at start point as you said. "No success by now"

I may be mistaken but EasyRoot is for KK 4.4.

Root H815 on MM 6.0 V20d?

Hi guys ☺,
I bought today G4 eu model,it came with Marshmallow 6.0 V20d version.
I want to root it because of Greenify and Xposed,to increase the battery time,maybe later to flash some rom but...
There is a lot of topics on this subject,I started to read but I'm lost right now...as far as I saw,I can't root Marshmallow without unlocking the bootloader,only Lollipop,right?
Is it a big trouble to go back from MM to LP?
I'm not new in this flashing and rooting stuff,I had (still have) a Motorola Razr XT910,I flashed it 100 times for sure for 3.5 years but I didn't had to unlock the bootloader (it's impossible anyway) and there's a custom recovery Safestrap,modified Twrp which allows to flash and use 6 different roms,from JB to MM,without changing the kernel...
I will be grateful if someone can point me in the right direction,to give me some useful links etc.
And is there some list which procesess are safe to freeze with TB and which ones I can greenify?
Oh,and the bloatware too...
Sorry if I'm demanding but I want to bring out the best from this phone
Thank you in advance

Hi,
root without unlocking bootloader works only on lollipop, right. Not sure if u can downgrade, but when, u will use "LGUP" tool with the "H81510D.kdz" file. Maybe there exists a pre-rooted kdz to flash.
If u want to root android 6, u need a unlocked bootloader. Rooted Android 5.1.1 or unlock bootloader with rooted android 6.x.x

Ok,I successfully unlocked the bootloader but now I'm stuck with rooting and installing Twrp...
I've downloaded BETA-SuperSU-v2.67-20160121175247 and TWRP-3.0.0.0-H815+ but there's a lot of metods,which one should I use?
Flash SuperSu+Twrp with stock recovery?
Install Twrp with adb command and then flash SuperSu with Twrp?
Install both with adb command?
I also saw somewhere that I must flash some other kernel that is already rooted...
I just need root and the Xposed for now,help me guys!

Im also Confused..Where can i find rooted kernel?
I already did this Method u said...But I got Boot Loop
Then I revover my phone with Lg Bridge
We need to find this.....I also Had Android MM with V20d

In my case I wasn't able to flash recovery on the stock kernel, I had to flash boot.img unpacked from the custom kernel like SimpleGX and only then I was able to flash recovery and full kernel through it.

the method i followed was-

2. flash systemless root with twrp
3. reboot
4. install flashify
5.flash twrp.img from your phone.
6. done
but there aren't as much benefits of rooting as any other phone. viper4android doesn't work. spirit fm doesn't work. xposed doesn't work properly.(these 3 were the main reasons for which i rooted)

I think doesn't need to install recovery to root the phone.
Just this:
1) adb reboot bootloader
2) fastboot boot TWRP-2-8.7.0-h815.img
Wait a second and it will open, on the phone, the recovery.
Once open go to Advanced -> ADB sideload and take a swipe to start it where it says "Swipe to Start sideload".
Now on the PC write
3) adb sideload BETA-SuperSU-v2.67-20160121175247.zip
( If it says after the instalation to install supersu etc just abort it)
And then, when installation is complete, press "Reboot System"
I rooted it this way, without install TWRP Recovery

I rooted it this way, without install TWRP Recovery

Yeah - but the question has to be asked - why unlock the bootloader and root and not install TWRP? If you've got as far as unlocking the bootloader you might as well make life easier for yourself and install TWRP - that way anything you want to flash in the future can be done without being tethered to the PC, and also allows you to take proper full system image backups etc.

Of course , i agree with you. By the way, we can't root g4 on m6 without unlocked bootloader.
And finally, i decided to pass twrp on my phone, for every file i want to install from twrp, and not every time to boot from pc
You're right
p.s. the first thing i did after twrp installed, was to install g5 live wallpapers
