Detailed Guide of Getting a Stock ICS Infinity unlocked

Hi Guys,
i decided to open this thread, because in my opinion my questions aren't really answered yet. So here is my question:
I have a Stock Infinity with 9.4.5.21 ICS Firmware and i want to get my NVFlash Files and finally install a Custom JB ROM on it.
But i don't really know in which order i have to follow the already postet guides. I think i have to do it as follows:
1. Unlock Bootloader with official ASUS APK
2. Gain Root (f.e. with the one-klick-root-tool)
3. Proceed with Nvflash (to make it Brick-Safe, because it seems that it happens very often)
4. Install Stock JB Firmware from Asus (But how to flash it?)
5. Flash Custom Recovery (f.e. TWRP with GooManager)
6. Flash Custom ROM (f.e. Clean Rom)
7. Be happy to have a non-bricked TF700
Can someone plz help me to verify these steps? I'm sure it will also help others who aren't certain about unlocking, too.

I would do this:
1. Unlock with the official tool and void your warranty, hope that Asus' servers work.
2. Root is not required at all for using fastboot or a custom recovery.
3. Do the NVFlash backups using fastboot and nvflash. Copy the created files from the tablet to your PC before you flash anything else.
4. Install a custom recovery using fastboot.
5. Flash the Asus JB firmware to get the JB bootloader. AFAIK this can be done from the custom recovery.
6. Restore custom recovery using fastboot, it was overwritten by the Asus JB firmware.
7. Flash custom ROM. If you use CleanROM, it's already rooted.

I see issue with your process. After step 4 (install Stock JB firmware from Asus site), after this you no longer have root/recovery, so you can't proceed to step 5 using GooManager. You should follow _that's recommendation, however at step 5, instead of flash the JB firmware, you just use fastboot to flash JB bootloader only, then you don't need his step 6. Go straight to step 7 (use custom recovery to flash custom rom).

Thanks for your help!
So now I think it should work like this:
1. Unlock Bootloader with official ASUS APK
2. Proceed with Nvflash (Afterwards boot into Stock Android to save NvFlash Files before continuing)
3. Install TWRP Recovery
4. Install JB Bootloader with ADB
5. Flash Custom ROM (f.e. Clean Rom)
6. Be Happy, because now it's unbrickable and ervery Custom Rom can be flashed
But i dont't know what I have to type into ADB to flash JB-Bootloader and where to get the Bootloader-Only-File?

PM me I give you JB bootloader zip file
No ADB, just use TWRP to flash JB bootloader just like you flash a rom.

I finally made it without bricking it
If anyone else have questions, feel free to ask me!
And thank you guys for your help

[Q] Update to Lollipop without USB and with root

Hi, my N5 has a problem, it has the USB port broken so i can't connect it to the PC. It now has KitKat 4.4.4.
Here is my problem:
I want to update to Lollipop but i can't do it with Factory image and/or Sideload because the USB problem.
I tried to "unroot" but i couldn't do it right, i've downloaded the 5.0 OTA and my phone rebooted with a red triangle and it said "error" i know this is because i still keep my phone rooted.
So i would like to know 2 things:
1) How do i unroot definitely? because i did it before but it seems it didn't do right, i clicked "unroot" on SuperSU (i read that sometimes when you press "unroot" it doesn't erase all the folders and files so you have to do by your own, but what files and what folders are they?)
2) If i unroot and i if update to Lollipop, can i be root without using the USB port?

Of you're rooted, why would you want the stock ota anyway? There are PLENTY of 5.0 Roms in the development section with custom kernels (custom kernels are needed in 5.0 lollipop for root). Flash one of those in recovery. Make sure you have the latest TWRP which you can flash with flashify if you can't fastboot flash using USB.

Is really needed to flash a custom kernel to get root on Lollipop? I'm asking because in this thread [ROM] [STOCK] Android 5.0 LRX21O - Stock/Flashable (11/12/14) FAQ nº 2 it says:
Q: How do I get root?
A: If you want to keep the stock kernel, use CF-Auto-Root. If you flash a custom kernel, just flash the newest SuperSU ZIP afterwards.

So i understand that we can have root with stock kernel, is this ok or did i misunderstood something?
If i want to flash a custom kernel, where can i get "SuperSU" Zip to get root? and does it need to clean something after or before flashing this file? caché, data, etc?

Yes CF AUTO ROOT will allow your to root the stock image. However since youre already rooted youre running into issues flashing it successfully. I attached the SU zip below. My recomendation is if you want the stock ota image, download it from the developer thread, flash francos custim kernel for lollipop ans then flash the root zip i have attached below. I would complete a full wipe of system, data, and both caches (not internal storage or you will lose all on sd card) before flashing. Once you wipe just flash the the rom, kernel and root zip in that order.

It worked perfectly!
I tried first with CF AutoRoot but it failed, but it worked with SuperSU.

[Q] Restore without downloading stock firmware?

I have Indian moto g 16 GB Android 4.4.4 I have a few questions
1. I just want to root it without any custom recovery or rom. Only to try apps which require root. I am not interested in custom roms, happy with stock rom. I found Modaco's method for it. But many users did not find it working. Is there any other SIMPLE AND STABLE method for it without messing up with stock rom and recovery?
2. If I successfully root it without custom recovery what will be steps to unroot it and revert it back to stock 4.4.4 so that I could receive future OTA. (i had rooted my HTC one x with custom recovery so I know about unlocking bootloader). Will this process include flashing stock rom as there is already stock rom in phone
3. Is is necessary to download stock firmware if someone decide to revert back from rooted phone to stock. I mean not everyone has fast Internet connection to download those big 400-500 mb . Zip files. I read somewhere that we can backup the entire rom after rooting. So why not flash that backed up rom for reverting process. Why need to download..and For backing up the stock rom do we need to root with custom recovery or the Modaco's method (stock recovery root) will work.
You may find my third question stupid but I am not much into this stuff.
Please answer my all questions whether it is yes or no. You need not to provide detailed descriptions but just clear my confusion. I couldn't find these type of questions anywhere else on Internet. So may be useful for other users too. Thanx

Anybody???

Hey...yes you can root it but doing so requires an unlocked bootloader(which wipes all data on the phone..so backup)
To revert root you'll need stock recovery(since you say you don't want a custom recovery, skip flashing the stock recovery) and untouched stock ROM...
you can either download a stock fresh stock ROM[recommended]
Or
You can revert all root changes you did to the ROM(Xposed, root,busybox, e.t.c.)
Cheers mate

thanx for replying..
Ok reverting will be enough? I thought stock rom is no more Pure after we root it either by stock recovery or custom recovery. And if i choose the reverting method, how much total apps will i have to delete/uninstall?

You'll will have to remove all root adjustments you made...if you can't remember them all, it's best to flash a new zip...but in my case it was only Xposed and root so I uninstalled Xposed within the app, then went to supersu to revert root.
Good luck

Thanx sir, Good Day

1. Try Paul O´Brien´s (that guy from Modaco) method. I rooted my Moto G with stock 4.4.4 like a month ago. No need to mess with the recovery, easy and simple.
2. There is an option in SuperSU that deletes all SU binaries from the phone. It is not needed to update though. You can update with SU installed, unless you modified any system files that the OTA wants to patch.
3. No, as mentioned in 2. Just unroot, uninstall xposed and you are done.

[Q] Flash stock recovery

Hey guys, yesterday I rooted my phone using KingRoot and XZRecovery to flash Super SU and now I want to flash back the stock recovery again because I want install future system updates without problems.
How can I flash it again? (I have my bootloader locked)

There is no accessible stock recovery on Xperia phones, the actual recovery partition will still be there. Dual recovery is installed on the system partition.
If your bootloader is locked you will be able to OTA, but you will lose root. The best thing to do is flash a pre-rooted flashable zip in the dual recovery you have. As soon as there is an update you can make a new pre-rooted flashable zip using PRFCreator.

D6603 23.4.A.1.264 Lollipop 5.1.1 downgrade

Hi all i just bought this mobile and i was curious to know if it was possible to install a custom rom.
I saw that the downgrade is the only solution to root and install custom recovery.
In my case i wish to know which file i have to flash with flashtool.
Thanks all

Yes

Update:
Downgrade --> Done
Root and DualRecovery--> Done
Backup DRM TA --> done
Bootloader Unlock --> Done
I'm trying to flash custom room rebooting in Teamwin recovery the flash goes perfect but after when i reboot the Z3 it goes in boot loop and i can enter only in the recovery the Z3 won't start at all.
I've tryied with 2 custom ROm and the original rom lollipop rooted and patched.
What i do wrong? I just put the custom rom in the Micro-sd card and i flash it using the teamwin recovery (before i wipe cache and Dalvik). Do i have to flash before the boot.img?
Thanks

You are either flashing an incompatible custom ROM or your boot loader is not unlocked.
Flash a stock FTF again, then goto the dialer and dial *#*#7378423#*#* then goto service info, configuration and post here what it says in the rooting status.

Well, neither of those require an unlocked bootloader, but that should not make a difference.
What boot.img are you flashing, both of those ROMs require a stock kernel.

Which procedure i have to follow to flash a custom ROM?
i normally copy the rom zip on the external micro SD card
i go to teamwin recovery i do a wipe and after i do install
The install finish and i click on reboot
DO i have to do other steps to flash the stock kernel?
i didn't flash any boot.img and kernel until now
UPDATE
problem solved i flashed the stock 5.1.1 kernel before to flash the rom and the bootloop disappeared.
Now i'm with the custom Mod there is any possibility to restore the DRM functions with the custom rom?

Well, if you only want to stay on these stock based custom rooms there was no need to unlock the bootloader. You only need that for truly custom rooms like cm or aosp.
If you want these rooms with drm keys then do this.
Restore your T A backup. This will relocate your bootloader
If this results in a boot loop, then flash a stock ftf, and do everything again EXCEPT do not unlock the bootloader this time
