JB Xoom root and flash?

Hi all,
There is just to much info here and I cant find what I'm looking to do... tried other sites also but not the same.
I have in the UK a stock Wifi GED Jelly Bean Xoom.
I would like to flash a custom ROM.
Am I correct in thinking I need to:-
Root - still not found a guide that does JB
Install Clockwork Mod Recovery
Boot into recovery mode and select wipe... install from .zip within CMR?
Pointers would be greatly appreciated...

I think unlocking and rooting would be the same regardless of the OS.
I also suggest you flash TWRP instead of CWM, both are fine either way.
Once you boot into recovery wipe cashe, dalvik cache, and data (factory restore).
Then flash ROM and GAPPS (for the specific ROM).
Just make sure the ROM you flash is designed for your device (there are many flavors of XOOM, each a little different from the others).

Irrelevant if you plan on using a custom rom.
1. unlock bootloader via fastboot - fastboot oem unlock
2. flash custom recovery via fastboot - fastboot flash recovery recovery.img
3. flash custom rom via the custom recovery you just flashed
Plenty of guides that go over this much.

Any pointers on what would cover a stock JB Wifi? - its all pretty bewildering if I'm honest.. I have no issues flashing my HD2 phone with Droid Clockwork Mod --> instal from zip... but the xoom doesnt appear to be that straightforward

Look at this guide that I came across. xoomforums.com/forum/motorola-xoom-development/15179-how-rookie-rooting-flashing-unrooting-under-one-roof.
Sorry it would not me post the link to the guide.

Just a thought..... Xooms sold in the UK do not have a JB update yet, so I would assume the Xoom may already have had its bootlaoder unlocked to convert it to a GED device and as part of that a custom revoery (like ClockworkMod) installed.
Is it worth trying to reboot into recovery to find out if you already have a Custom Recovery installed ? Might simplify the process somewhat......
I must admit, I've no idea what the stock recovery would look like though seeing as I GEDified my Xoom within a week of getting it

[Q] File recovery From Bootloop'ed Nexus 4

Hi,
I Need help .
I have nexus 4 with stock ROM and stock recovery.
Two days after OTA update to Lollipop, the phone got stuck on boot-loop.
The problem is that on the phone i have a very important voice recording of a cop that says he will lie in court.
The court time is coming and i need that recording!
Everywhere i looked, no one has an idea how to recover a boot-loop'ed phone.
The 2 options that people recommended are:
1. RE-Flash the ROM.
Maybe it wont delete the files.
2. Wipe everything and hope that the file is recoverable with one of the software's.
A. What do you recommend?
B. Did someone try any of the recovering software's with any luck of actually recovering?

Your bootloader is locked, correct?

If your bootloader is unlocked you can try flashing TWRP recovery which has a built in file manager and mtp function to copy files to computer. You can also try to "dirty flash" another lollipop rom which will not wipe the data, but may not work.

Yeah, this is the only option, however, this can only happen if his bootloader is unlocked

unfortunately, the bootloader is locked.
what are the chances that "Dirty Flash" wont delete the files?
and what rom should i flash? the same build or maybe try to flash kitkat insted...?

Unfortunately, as far as I know you can't flash any Rom's while your bootloader is locked. You need either fastboot or a custom recovery to flash a custom ROM and both need an unlocked bootloader.

and flushing the same STOCK rom that i got as OTA should work or does it only work with custom ROM's?

i've looked again.
seems that the bootloader is unlocked!
so, should i flash a TWRP recovery?

Yes, after you've flashed twrp you should be able to access your files from a computer if you're booted in recovery.

soooooo.....
i flashed the TWRP Recovery.
very easy. no errors.
and it shows as the storage is completely empty! as if someone in all this time wiped everything...
so now, what recovery software do you know/used/heard of?

When the storage is completely empty, are you booted in recovery, the bootloader or just trying to boot normally? When you say it's empty, do you actually see the device on your computer? If so, is it completely empty with no folders or files or anything, or just stock stuff?

Can you check mount and make sure all the storage volumes are mounted? It's usually blank when they are all manually unmounted.

Bricked my LeEco Pro 3 while installing CM13, need some help and advice.

Hi Guys,
Long story short, I bought the LeEco Pro 3 US version due to the awesome Tmobile network support. The modem supports band 12 and WiFi calling and I was happy with it. But eventually notification issues and the horrible EUI got under my skin and I decided to install CM13 keeping the phone as untouched as possible so that I can revert back to stock whenever needed.
I followed below steps:
1. Enabled developer options and enabled USB debugging.
2. Went the Developer Options and enabled OEM Unlocking.
3. Did adb reboot bootloader to get into the bootloader menu.
4. Did fastboot unlock-go command to unlock the bootloader. I noticed that if I did this command and rebooted the phone, the phone reverted back to being locked again. But I could run the command again from bootloader screen and unlock it (as long as the developer options had the OEM unlocking enabled). So I was never permanently unlocked, just unlock at will whenever I wanted.
5. Then I downloaded the twrp.img file and from fastboot screen i did fastboot boot twrp.img, which booted me inot twrp screen. I was able to switch the language to english but i didnt do the permanent system modification. I did not root the phone as well through the menu.
6. Now, I plugged in a USB OTG drive in the phone. Usb OTG drive had CM13 ROM + Gapps on it.
7. Using the TWRP menu, I did a factory data reset and made a backup of all partitions of the LeEco Phone and saved it into USB OTG drive.
8. Then I installed the CM13 rom on the phone. Followed by Gapps and then rebooted the phone. The phone wouldnt boot.
9. I immediately rebooted the phone into the fastboot menu and tried to run the fastboot boot twrp.img, and got an error message that the device is not unlocked. Which is when i noticed that the phone is bricked.
So Long story short, I have a locked bootloader and I want to to retain my modem. I was given a suggestion to boot into the stock recovery and put the x720 update.zip file and install it. But that would flash the CN modem as well. Can I delete the modem file from the CN rom and flash the update.zip? Can someone help me there? All I want is the modem for the US rom and CM13, thats it.
Thank you guys for reading this post, it helps to talk to XDA about such issues, my wife would just kick my butt because I broke a phone, again!

Did you wipe the system using twrp before installing CM?

No I didn't wipe the system before installing CM13. Usually the ROM installation scripts do system wipes.

This is the reason why I am hesitant to do this thing as there are no clear (step-by-step) procedures and there is no solid benefit (in fact your will lose some features). Can't it be possible to just create a CM or any other ROM that could be downloaded and rename into update.zip and load it directly renaming the X720 ROM? ^_^

Try unlocking bootloader again with fastboot method as you didn't do it the first time. Then try fastboot boot twrp.img

He will not be able to unlock again due to the fact that he installed CM13 on an unlocked bootloader. I did read where you can flash the CN bootloader on a locked bootloader. Look at post #44 from the "X727 (US Model) Persistent bootloader unlock from 5.8.019s" thread.
http://forum.xda-developers.com/le-pro3/development/x727-model-persistent-bootloader-unlock-t3500388
"I finished the setup and run fastboot again and it is good so for anyone having the same issue as I was having of not able to unlock, just run: Fastboot Flash aboot emmc_appsboot.mbn get the file from dr4stic zip file"
Followed by post #47:
"Yeah I can confirm that flashing the aboot worked like dish soap on a squeaky hinge."
If that doesn't work then you will need to install the CN rom using the stock bootloader.

I ended up installing CN ROM as my last resort. I have an unlocked bootloader and twrp installed now, with CM13. Now I need the way to go back to US modem so I can get all the bands.

1. Download the rom from here: https://www.androidfilehost.com/?fid=601275311581036717
2. Unzip and extract the NON-HLOS.img file.
3. Reboot into fastboot mode.
4. Flash the modem "fastboot flash modem NON-HLOS.img"
You will not notice a change in the modem version in "About Phone" as they both report Baseband version MPSS.2.0.c1.9.1-00010. Who knows, they may be the same.

That is from the US baseband. That rom will convert a CN install back to a US install.

Okay, if you chose to use the long route and installed the Chinese ROM, you can still get back to the full US version, complete with all LTE bands. dr4stic is responsible for this gem, and was my way back to US ROMdom.
To go from Chinese or Custom ROM back to Stock US version:

Sorry for the late answer but to add to that, it happened to me that the ROM didn't have a wipe script thus bricking another of my device. I reinstalled it after wiping the system and it worked.

need help with my grand prime sm-g532f

hello guys,
is there any custom frimeware for the galaxy grand prime sm-g532f ? i looked everywhere but can't find one.
i need one because there is no more space in my phone, the system took almost everything, 6.5go of the 8 availble, so i can't install big apps even with an sd card ! any solution ?
i was about to install a stock rom, but someone told me that it will take the same space as my current rom .
thank you.

I don't think any developer is interested in this device, it could be due to non-availability of unlocked bootloader, firmware sources, etc. I am thinking of getting rid of mine and move to another device that supports open hardware/software.
In possible solution if you managed to root it the use system app remover to get rid of Samsung bloat.
Good luck.

All phones when you unbox are on factory ROM (aka stock ROM). I think you are referring to rooting and installing custom recovery, I failed and phone always go into boot-loop making me to re-flash stock boot and recovery images.

thanks, i think i will try to root my phone, maybe it will work for me. my last hope :/

Please post your results, I am hopeless with this severely bloated device.

Update:
Managed to root using TWRP.
1. Install TWRP recovery.img using ODIN (Windows) or Heimdall (Linux) including SU. Details in this thread:

Is it OK to clean flash Factory Image in TWRP?

I want to make a clean Install of factory image (Android 8.0 Oct) on my Nexus 6P with TWRP.
Should wipe Dalvik, Data, System and Internal storage, then move the stock zip file (That I downloaded from google's web) from my computer to my phone and just install in TWRP? Will it work?
Device is unrooted, only has an open boot loader, I just want to make a clean install of Android 8.0

If you wipe your internal all your downloads and your factory image are gone.
Sure you can flash the unpacked *.img with twrp, but don't try to flash the bootloader or radio with twrp.
If you really want a clean start and wipe everything, then you should flash the factory image with fastboot. This will update your bootloader and radio too.

Hi coremania, I have a few questions towards this method.
1. If the stock image is stored in either external SD card OR USB OTG, even then will there be any problem installing the the stock rom back using TWRP?
2. If the boot loader is unlocked, should one has to re-lock it first before reinstalling the stock rom either thru' TWRP or thru' Fasboot commands?. and finally,
3. Is it not advisable to flash the stock rom from the full factory image using TWRP rather than Fastboot?
(As I think it is easier to flash thru TWRP than typing those ADB commands in Fastboot).
Thank you for your inputs.

If you decide to flash and test some stuff the bootloader should be always unlocked. If anything will went wrong and your bootloader is locked you're mostly f***ed. Never relock your bootloader until you want to sell your device.
I mostly use flashfire to flash stock and custom roms, TWRP is ok too, but it's easier to keep root and TWRP with flashfire by flashing stock images. Do not flash bootloader and radio with flashfire, never ever !!! There are TWRP flashable zips for bootloader and radio here on XDA, you only should use these with TWRP, but the safe way for bootloader and radio is fastboot for sure. Fastboot is the safest way for flashing stock,
but not absolutely necessary, you have to decide this for yourself.
Edit: to your first question, I never flashed with USB otg on the n6p, but I think yes it should be fine.

I hope someone here can help answer this question. I also want to flash factory image version 8.1.0 on my nexus 6P. But somehow my phone is not recognized by any computers I tried to plug it in. When I plug in the usb cable to the phone, it doesn't pop up the usb notification to choose MTP for file transfer. Then I try with Developer tab in Settings to choose it manually (USB debugging is enable) but it still doesn't work. My laptop has been updated with android usb drivers and other stuffs. I have a second phone (Oneplus 1) and it's recognized by my laptop the moment I plug it in. Please suggest any solutions to fix this. Thanks everyone.

Check your cable, or try a different with different port.
In the Dev options you can reset the debugging options, i guess a reboot is necessary afterwards.

Thank you for the clarification. So, far I have not faced a situation to flash my custom recovery either thru' TWRP or thru Fastboot. Instead, I am using my Nandroid backups taken from TWRP and using it to restore my system after I try a custom rom OR upgrade my system with the latest Magisk version for a systemless root. So far there are no issues. But, I wanted to be aware of the methods to go back to stock (without any user installed apps/data) if need be. I read in some forums that we need to re-lock the unlocked bootloader if we want to go back to stock rom using fastboot. Otherwise, the system will not be installed alright and might cause a bootloop.
That's why I wanted to clarify.
Thanks again for your inputs.

You don't need to ever relock your bootloader. If you want to try stock and use TWRP try SuperXe 8.1. It's just flaahable stock with some extras you can opt out of your not intereseted.
