[Q] Flashing a Rom. - Nexus 4 Q&A, Help & Troubleshooting

I've been trying to install LTE on my T-Mobile phone through this thread:
http://forum.xda-developers.com/showthread.php?t=2358931
But, I'm really lost.
I have unlocked the bootloader and rooted my Nexus 4. However, when I boot into recovery mode, I just get the Android lying down with the red triangle. I do not have TWRP/Cyanogenmod installed on my Nexus, so I'm not sure how I get into the screen to let me flash the radio, let alone flashing the radio itself?
Could someone point me in the direction or list the steps out, so I can learn and follow?
Sorry in advance. I'm coming from a 2.5 year old iPhone and I really have no clue how Android works. I'm trying to learn, but as technology gets better, the more difficult it is for me to learn.
Thanks in advance.

You need to flash a custom recovery. (Cwm or twrp). Read the stickied root guide at the top of this forum for detailed instructions on how to do so.

I read that. Where I get lost is:
Boot into ClockworkMod Recovery by turning your device completely off. Hold volume up, volume down, and power until the green Android with the open chest is displayed. Navigate to "Recovery Mode" with the volume buttons and select using the power button.
Remember to have a recent nandroid before continuing!
So, I remember flashing a custom recovery when I rooted the phone. But I didn't download TWRP onto the phone, and it was just temporary I think (fastboot -c "lge.kcal=0|0|0|x" boot customrecovery.img). So now, when I try and do a custom recovery, my phone boots into the Android guy and the red triangle.
When I flash a custom recovery, does the phone have to be connected to the computer? Should I install TWRP onto the phone? Did I miss a step somewhere? Perhaps I should not have used the temporary custom recovery, but all I plan on doing is flashing that radio to get LTE...
Any guidance on this?

You could always just boot the custom recovery again then flash the LTE zip.
However, you should really just flash a custom recovery so that its always there when needed.

DEsire Z/G2 added to official bootloader unlock program

Didn't see this in General so thought it would be worth adding, especially since there have been many threads lately with new users wanting to root their phone and then getting scared of the guides.
Now there is also the option to go the official way to unlock the bootloader.

Not quite. It can probably explained more accurately but the gist of it is this:
An unlocked bootloader is what allows you to flash custom roms to your phone.
Root access simply grants you the rights to mess with your phones rom whichever way you want.

I thinks that's pretty much it, once you have unlocked your bootloader you'll be able to flash any custom rom you like. Though it'll probably a bit tricky on the first go since you don't have a custom recovery yet, so I believe you'd have to flash some pc10img.
Still it's commonly to believed to be the better choice to stick with the more exhausting solutions posted around here, since HTC will register your phone if you use their tool. At least for the time being they claim that by using their way, your warranty will be void.
I've unlocked my desire z through the htcdev.com website.
Bootloader is unlocked, S-on..
But I can't get a rom installed, it gave me an error while trying to update from the recovery mode (apply update zip) using a stock rom with root.
Akward..
So now I've unlocked my bootloader, but still can't change my rom..
Anyone know how to do it after you've unlocked the bootloader?
flash custom recovery first, from there flash the rom
if you're s-on, bootloader is still locked....

But when I press start clockwordmod, it says that my phone is not rooted..
While I press "flashcockwork" clockword mod recovery, I get an error.
än error occurred while attempting to run privileged commands!
I'm doing something wrong..
pretty annoying
I get unlock my bootloader today, and YES there is S-ON, but on the top is written in hboot menu big letters UNLOCKED (How you thinks, htcdev joke?).
I've installed clockworkmod using fastboot:
Code:
fastboot flash recovery clockwork_mod_for_vision.img
Then put off battery and turn on phone with volume down + power, I pressed 'recovery' menu option. Clockworkmod runs correctly. Then tried last stable CyanogenMod 7.1.0, flash was done without errors, I wiped out what's need (cache, data). Next I tried run phone, but freezes at splash (green htc letters on white background).
I tried also miui mod, but Ive got only MIUI splash screen nothing else.
Then I restored my htc from backup (done before flashing using clockworkmod) and Im still on the stock htc android 2.3.3.

Hi,
I also unlocked using the official method of unlocking the bootloader. How can I get root and install CM7 now? Even to install clockwordmod its asking me root the phone.

1. boot to fastboot mode, flash a custom recovery (recommand ClockWorkMod), power down the phone.
2. put your downloaded update_cm7.xxx.zip into sdcard, boot phone into recovery
3. choose in the recovery, first "wipe data", then "install update from sdcard", choose the zip file you just put in.
4. choose "reboot system"
that's all to go.

Booting problem is mostly kernel related, do you have logcat output? (run "adb logcat" and boot the phone)
I encountered with the situation (w. another phone) that the recovery can't flush the boot partition during the recovery installation, I have to extract the boot.img file from the zip and flash it manually in the fastboot mode (fastboot flash boot boot.img)
EDIT:
That was a EVO3D with UNLOCKED HBOOT, I believe you're having the same situation, try my method or may others make out a better perfect solution ? (not my own phone, I just helped with its owner, no time to dig the details)

My friend has an officially unlocked Desire Z as well and I gave him these instructions to try it out, he has the same boot problem (stuck at splash screen). Maybe this information should either be stickied or added to a faq until there is a real solution to the problem (unlike this workaround), updated cwm or something like that.
Anyway thanks for sharing this information.
HTC bootloader unlock tool is quite restrictive. It still leaves you S-ON, so you won't be able to flash a new hboot or radios.
I recommend avoiding it and using the current well-proven methods from the XDA Wiki.
Sent from my Desire Z running CM7.
Its working now...
Steps I followed:
1. flash recovery using fastboot
2. Do a nandroid backup using recovery
3. flash boot.img using fastboot
4. reboot into recovery
5. wipe data/cache
5. install update for CM7, and gapps
Also make sure before doing any of these steps you have copied CM7 and gapps update onto sdcard.
Thanks everyone for helping out.
I am experimenting with this myself and I don't seem to be having the same issues flashing a boot.img from an update.zip in ClockworkMod recovery with the official HTC unlocked bootloader that others are having. Maybe it is the version of the recovery that is the issue? Which version is everyone trying to use? I am using the 3.xxxx version that is linked from the wiki. I have had other problems with the 5.xxx version and tend to stick with the older version for that reason anyways.

[Q] can't get to recovery mode after unlocking

Hi, a bit of noob but i did googled alot
My plan was:
Unlock and root with nexus 4 toolkit.
Do nandroid backup
Flash PA rom.
step 1 went okay,
afterwards i tried to go to recovery mode inorder to backup but i got the lying android with the red warning sign.
I did backup using Rom Manager and nexus 4 toolkit but I'm worried I can't get to recovery mode if something goes wrong.
How shall I proceed before flashing the rom?
The robot lying on it's back is the stock recovery. You need to flash CWM/TWRP before you can do a Nandroid

Do yourself a favour and learn how to use ADB instead of toolkits that do more harm than good if used by inexperienced users and you`ll learn to do it the right way.

If you have Rom Manager Installed and are rooted you should be able to install CWM thru it.
don't have flash recovery on rom manager
I don't have the the "Flash CWM" recovery option on rom manager,
I've attached a screen of what I do have,
I did explore the Recovery Setup but wasn't able to do anything usefull.
Any advice?

according to ROM Manager you already have CWM installed and its up to date. Have you tried booting into recovery using ROM Manager?
When I press reboot to recovery directly from rom manager it works...
I'm just affraid that in case that I brick or mess up something I won't be able to get to stock recovery mode.
volume down + power button = bootloader (android on his back) also called fastboot mode
use volume buttons to scroll to recovery then press power button to select it
you should then be in CWM recovery if its installed correctly.
If you are using a custom recovery your stock recovery is gone. You would have to use fastboot to flash the stock recovery image back onto the phone. Its rather simple to do as is flashing the stock image file back onto the phone.
that is why I started this thread.
After I Unlocked and rooted I wasn't able to fastboot and go to recovery mode, it showed my the android on his back.
I've tried it again now and it still doesn't work.
but when I boot directly from rom manager it works...
Edit: I posted before you edited your comment.
even though I don't know adb, should I learn and follow this guide?

There is a bug that restores the stock recovery after a reboot and there should be an option in the root toolkit to fix it. Not saying this is what happened but it may have. The stock recovery is stored in system memory somewhere and the bug fix just removes it so it won't restore itself after reboot.

I call it a bug because its an annoying feature. There are a number of threads no how to remove it but using a toolkit to do it is just as easy.
thank you,
but after I've read what you wrote about the bug I open the nexus root tool kit and then I realized what I should have done.
I pressed Custom recovery checkbox and rooted again.

Won't boot to TWRP recovery after flashing to 4.3

Hi all, I'm new here (great place, very informative) and pretty new to the Android scene in general.
As the title said, My AT&T S4 won't boot to recovery after I flashed 4.3 JWR663. Worked fine before and 4.3 is working great, but I can't get to TWRP. When I hold "power + volume up" I get the blue text dialog indicating its going to boot to recovery and the phone just shuts off. I can boot to download mode, but haven't done anything out of fear. I'm not rooted (which is what I'd like to do once this is fixed).
Should I try and re-flash TWRP? Any other suggestions? Feel free to break it down like you're talking to a child. Thanks in advance.
Try flashing it. Get goomanager from the play store. Open it and hit the menu button. Hit install openrecoveryscript.

You'll need root to flash a recovery with GooManager.
How did you install 4.3? I assume that it's a custom 4.3 as I don't think it has been officially released yet. If it's custom, I'd assume that the ROM had been rooted as well...

I was rooted, but the ROM had it removed and I need to flash Chainfire to get it back. But I can't get into recovery to do so. I think the ROM was done by Jah0n
Is it safe to flash TWRP with Odin now? If so, could you point me to the directions to help me do so. Thanks again for the help.
Found a fix!
My recovery is fine. All I did was power down, try to boot into recovery with "power + volume up + home" and just when the phone vibrated to boot into recovery, I let go of the power button but continued holding the other buttons. It booted into TWRP just fine.

This thread is about the Samsung Galaxy s4.
Hi there. I'm new of this forum and even of the Android customization scenario. I have a Samsung Galaxy s4 i-9505 with 5.0.1 firmware and build LRX22C.I9505XXUHPK2. I've tried to install TWRP with Odin3 (so without root my phone) and all the procedure goes well. After reboot, I have turned-off my phone and I've tried to enter in the TWRP's recovery mode (using the combo buttons: VolumeUP + Home button + Power button) but the "TEAMWIN" logo didn't appear and the normal "Android Recovery Menu" were visualized.
I need some help to undestand if I did some mistakes during the flashing process. I've used the last versione of TWRP (3.1.1-0 for jfltexx). Any help will be appreciated. Thanks for your attention to this matter.
If you want to root with TWRP, try this for the gt-i9505:
open Odin 3.07 and uncheck everything except r reset time;
download the tar version of twrp for the gt-i9505: https://dl.twrp.me/jfltexx/
download the latest version of supersu.zip and copy it to an sd card or the phone's internal storage: http://www.supersu.com/download;
place the sd card in the phone if twrp has been saved to the sd card from the step above;
connect the phone in download mode and flash twrp in Odin's PDA slot;
when you see the word "reset" in the status window, remove USB cable from the phone, remove battery, replace battery, boot into recovery, install supersu.zip, reboot.
If you just want to install a custom ROM, copy the ROM to the internal or external sd card, install twrp, and install the ROM. Root is not required to install a custom ROM, only a custom recovery.
Warning: whenever you flash anything to a phone, it is always possible for something to go wrong and you must be prepared to deal with any consequences. I have used this method for several note 2, note 3, s3, and s4 phones without any issues. With this being said, I can't guarantee that the above steps will work for your phone or your phone won't be bricked.

Recovery won't flash

I had to do a complete wipe from the computer and flashed clockwork mod recovery. Since it was likely an old version I had the double 0 partition problem which I fixed by manually moving the files. I tried to update the recovery to twrp, but it won't flash using goomanager. It downloads and says it's flashed but it's not there.
I also seem to have a weird problem where I have to push the power button to get it to boot past the Google screen. If I don't push power it gets stuck there forever.
Any ideas?

This might be an odd question, but have you tried just updating CWM first, and THEN flashing TWRP? Sometimes the flash won't go smoothly with an older version of one recovery to a newer version of a different recovery- not sure why, but that's just been my experience. I would update CWM first then try flashing TWRP.
Also, if goo is not working for you, you could try Rom Manager to update CWM and then flash TWRP. It can flash either. (If you really want to flash via the device).
Otherwise, (me personally) I'd just use adb fastboot to flash a new recovery.
Hope that helps
Thanks I will try that.

Ahh, that sucks! How are you *attempting to* access recovery... via reboot menu, via adb, or via 3-button press? It shouldn't matter, but you could try all three methods to see if any way will give you recovery access. Then, if/when you manage to get in, you could reflash again straight from recovery. I'm going to do some digging to see if I can find a better solution. I KNOW I've read about the same issue before, I know there's a solution... I just have to find it again.
Worse comes to worse, you might have to reflash stock recovery then reflash custom recovery. Might be a corrupt recovery img, but I will check and try some things out and let you know what I find.
Edited to add:
Yes. there was a bug in the older bootloader that bypassed/refused access to recovery... so since you restored stock, you probably need to update your bootloader to at least to version 4.18 (via fastboot). THEN you should be able to access recovery. I can't add links, but I can give you a text link once I find just the IMG file instead of the full firmware. Honestly, I never do backups so I don't have the file on hand. However, I may do one backup at least so I can extract my boot img and give it to you.
OK, so I found the info I was looking for.
From Elsewhere:
Steps:
Install latest nexus 7 bootloader.
This fixes the boot loader bug and now you can enter recovery from the bootloader screen.
Update the bootloader to at least 3.18. Make sure NOT TO DELETE THE BOOTLOADER!!!!!!!!!!!!!
I cannot emphasize this enough!!!!!!!!!!! I bricked my first one this way.
Use
fastboot flash bootloader C:\>>>>>>\bootloader-grouper-3.18.IMG***

Do NOT erase bootloader before you flash the new one. And after you have flashed the new one type;

and check the bootloader version to make sure you succeeded.

***Or whatever you name the boot img file!***
https://dl.dropboxusercontent.com/u/19608328/boot.img.zip --> This is from MY Nexus 7. It's Bootloader version 4.23, and works with JB 4.2.2- it does NOT have the recovery access bug.
https://dl.dropboxusercontent.com/u/19608328/recovery.img.zip --> This is a copy of MY CWM, which I just updated to 6.0.3.6 yesterday.
I'd flash the bootloader, then flash your recovery of choice. Not being able to access recovery is a bootloader issue, not a recovery issue. The fact that you restored/reverted an older full firmware put you on an older bootloader that would not allow users to access recovery.
Try the new(er) bootloader, it should work. My device is a 16gb grouper Nexus 7 running 4.2.2. Before that, it ran 4.1.2 without any issues, so it should work to resolve the problem you're having.

Nexus 10 stuck at Fastboot Mode....I think

I have a Samsung Google Nexus 10 (Wi-Fi) GT-P8110HAAPHE Which was running Android 4.4.3 (I think but it is definitely the latest version) and I simply wished to root it.
I started following a video on Youtube and now I am stuck at what I think is called the Fastboot mode where My options are to scroll through START/RECOVERY MODE/RESTART BOOTLOADER/POWER OFF. I was using the Wugs Nexus Root Toolkit v1.8.3.
No matter which I select it returns me to the screen with the START option. When I select POWER OFF it does indeed power off but when I switch it on again it returns to the fastboot mode START option. I can get into download mode if that helps.
I did create a backup but cannot restore it.
I have done some research and downloaded the Android SDK Suite and fastboot/ADB and drivers etc ready to try and recover but I don't know where to start.
I have a Samsung Galaxy S3 which I have rooted and installed a number of different ROMS on so I am familiar with rooting but not sure if I can use Odin or something similar.
I think I have included all the information I have and hope someon can assist.
Thanks.

I have a Samsung Google Nexus 10 (Wi-Fi) GT-P8110HAAPHE Which was running Android 4.4.3 (I think but it is definitely the latest version) and I simply wished to root it.
I started following a video on Youtube and now I am stuck at what I think is called the Fastboot mode where My options are to scroll through START/RECOVERY MODE/RESTART BOOTLOADER/POWER OFF. I was using the Wugs Nexus Root Toolkit v1.8.3.
No matter which I select it returns me to the screen with the START option. When I select POWER OFF it does indeed power off but when I switch it on again it returns to the fastboot mode START option. I can get into download mode if that helps.
I did create a backup but cannot restore it.

This is why I tell people not to use toolkits. Since everything is automated, it's hard to tell what went wrong and where. When it comes to Nexus devices, toolkits are entirely unnecessary IMO. These Nexus devices are so super simple to flash manually it's ridiculous. /END RANT
Okay. Sorry about that. Now, back to the issue at hand. The menu you are describing is, in fact, the Bootloader (aka Fastboot mode). Prior to using the NRT, were you completely stock? Was your bootloader already unlocked? To me, it sounds like you may have wiped your OS. Have you tried flashing the 4.4.3 factory image?
I was completely stock. Whilst using NRT I believe I had just succeeded in unlocking the Bootloader and the video then stated that with 4.4.3 a Factory reset was required which is what I did but I did not realise that deleted the O2. I thought that was on a protected partition like my S3 phone.
I can't flash the factory image as I can't get into recovery or is there another way of doing it?
I suppose where tablets are concerned I'm a book but if you could point me to any instructions on how to flash manually I'm hoping I can recover my tablet. Thanks.

Sorry, predictive text is rubbish. O2 should read OS and last paragraph I'm a book should read I'm a noob

Dont know how you got your os erased. But im using a custom recovery since I got mine so maybe the stock recovery erses the os when doing a factory reset. A factory image cant be flashed via recovery and must be flashed via fastboot. Its really easy. But it will wipe the entire device. If you dont want to wipe everything you need to edit it..

I don't mind wiping the device but I cannot access Recovery Mode. When I select RECOVERY MODE and press the Power button to take me there it just returns me to the START screen.
I don't know if the fiollowing is relevent but it displays the word START vertically in the top left of the screen and next to it
Device Information
Product Name: manta
Variant: wifi
H/W Version: 8
Bottloader Version: MANTAMF01
Carrier Info: None
Serial Number: Don't think I should show that
Lock State: Unlocked
Reboot Mode Flag: None.
I have tried RESTART BOOTLOADER and that brings me back to the Start screen but still cannot access RECOVERY MODE.
Holding down the Power Button and Volume Up/Down brings me back to the Start screen again
I can get into DOWNLOAD MODE
Is there ANY way I can flash anything onto my Nexus 10 without using RECOVERY MODE like using Odin or Heimdall with a Samsung phone?

Great news everyone..........well for me that is :laugh:
Thanks to Androidbeat.com I now have a fully operational Nexus 10.
Just in case anyone else was following this I did it by downloading all the necessary files into on folder on my Windows Desktop, opening a Command Prompt from there and followed the instructions.
Thank you to those who offered advice here and although my Nexus 10 is showing itself to be unlocked I think I'll give a miss to rooting it and just suffer the limitations rather than risk bricking it again.

Glad everything worked out for you. Just an FYI for future reference, the stock recovery factory reset does not wipe the OS (at least it shouldn't). By default, AFAIK there are no custom recoveries that will wipe your OS either while doing a factory reset. It must've been something with the toolkit.
Regarding root, it's super easy to get root on this device. All you have to do is download the custom recovery image file of your choice. I prefer Philz, but you can use CWM or TWRP as well. Then, download the latest SuperSU zip file (I believe it's v1.99r4 now). Simply fastboot flash the recovery image, boot into recovery, and install the SuperSU zip, and you're good to go. The whole process takes two minutes, and no toolkit required.
