Donwgrade possible? - Nexus 5 Q&A, Help & Troubleshooting

Hi everyone,
if I get a Nexus 5 with 5.x on it, is it possible to just downgrade with the factory images (to lets say 4.4.4) as usual or is it a problem that the desired version was never really on it?
thx

Any versions found here can be used https://developers.google.com/android/nexus/images
For the N5/Hammerhead
So yes, you can downgrade if you desire. If you have problems doing so, I would recommend using the LG flashtool, then install what you want from there

Thanks a lot :good: I didnt know this tool

You don't need to use any tool. Just install this: http://forum.xda-developers.com/showthread.php?t=2588979, download image of your choise and run flash-all.bat.

Thanks. I already have them installed and will get the image and flash it. My actually thought was, if there are problems, when the device never really have the build installed i wish to downgrade to. Are there technical barricades?

[Q] I made a stupid mistake. I formated data and now I don't have any OS.

Hello, today I decided to unlock, root my phone. I also decided to install new rom. And everything went fine but befor installing I insted Factory reset I formated data. I don't know what I was thinking. It may be that I was using TWRP Touch for a first time. Can somebody help me get back to at least to Stock if it is possible. Is it possible to connect phone in TWRP to transfer data from computer to it?

Does mount usb work on twrp? If so you can copy a rom zip to your device. If not than use search here on xda or google you probably need to unroot again and restore with a factory image.

Moutning doesn't work.
I found this: http://forum.xda-developers.com/google-nexus-5/general/tutorial-how-to-flash-factory-image-t2513701
Will this work for me? I was never in this situation before.
You can either use adb to push a ROM zip to your phone, or just flash the stock images to your phone. http://forum.xda-developers.com/showthread.php?t=2513701

Either Xubuntu or Windows 8.1. What is prefered? Xubuntu probably because you don't need drivers.

You should use Windows 8.1 for this tutorial. It's aimed towards Windows and the command prompt. Followed word by word, that is, for Windows.

there is no way to flash an equal version of trust zone with rsd.
he needs to replace all the files anyways.
2 possible solutions come to mind,
1. flash the next newer firmware with rsd, if that fails,
2. flash the same version with Mfastboot, if that fails, try the newer version.
figuring out how to bypass the tz fail is easy, but it will just throw another error when it gets to the next file you cant downgrade or re-write equal. thats why the steps i have suggested should be tried.

yes, he must replace files IF current rom defferent from mine, i use latest stock rom released.
and i assume he know how to put md5-hash to the .xml file if he wish do some experimental :laugh:
Keep in mind he flashed 925 FW to a 926, he could be toast.

correct. i think he stuck at bootloader.
You may be right, but it doesn't hurt to at least try the most correct method to fix it.

i think what he got when research with "firmware" or "ROM".. worst case is softbrick. correct?

Look again on that window (it's also in the screenshot),
there clearly is a 5.11 firmware (in the right frame of the app).
Took me also quite some time until I discovered it in the past - I thought I was stuck with only the latest firmware

5.11 is just the update code, it is the latest Android 6.0.1, you can install all regions but default one is much more compatible.
Just download and flash, do not forget to select ALL WIPE options. You have to wipe for downgrade.

You did not follow all steps, if you want to do something you think right, not blame Flashtool or anyone.
FTF should be about 2.6GB-3.0GB..

T-Mobile Revvl OTA captured

I managed to capture an OTA update for the T-Mobile Revvl. It contains the boot image, preloader, and a bunch of other system stuff. If we can mod this for root or custom recoveries, that would be great.
Here's a mdeiafire link to the OTA update.

Dirtycow uses kernel so you need to check what security
version kernel you have it doesn't go by Android version. Or try Rowhammer.

Tried Dirtycow anyway, the stock Revvl is not vilnerable.
Why don't you spit out all of the root exploit tools you know of and quit wasting my time?
I am willing to jump on the bandwagon and help developers to gain root access for this phone and the plus version. Fairly tech savvy with adb and fairly comfortable to be able to redirect if something went wrong let me know what's needed!!!
Would love to see this happen! Have one if you need someone to beta test

Need help rolling back/unrooting my phone

I rooted my phone last week because I wanted to use substratum to theme my notifications. Since then, I've run into a bunch of frustrating problems.
Current Model: OnePlus 7 Pro 12GB version, build xXx_NoLimits_7.7 on OOS 9.5.11-GM21AB
Problems:
Phone used to be 9.5.11-GM21AA but now it's 9.5.11-GM21AB - does this affect anything?
Substratum hasn't worked in stock+root, and 2 different ROMs I've tried
Favourite app of mine doesn't work properly and I think it's because I'm on build 9.5.11 and not 9.5.10
How I messed it up: Started by rooting and trying to install Renovate ICE Rom, installed the wrong file which converted me to 9.5.5-GM21AB. Then I updated to 9.5.11 but it remained AB. I tried several times to unroot, roll back and get to 9.5.10AA but it always kept itself at 9.5.11AB. Sometimes my wifi would break. I currently have xXx NoLimits Rom installed.
Desired outcome: I want to unroot and roll back to 9.5.10-GM21AA stock
Any help is greatly appreciated. Thank you!

Thanks, that was super easy. MSM automatically rolled back my phone to 9.5.3.GM21AA.
I have one more question - if I want to update it to 9.5.10GM21AA, how would I do that? If I update through the system, it will take me to 9.5.11, which I do not want. If the process is easier if I'm rooted, I already did that. To top it off, my substratum is working now after I reset my phone to how it is now. All I need is to update it to 9.5.10 and I would be sooooooo happy .
Thanks in advance!

Go to https://androidfilehost.com/?w=files&flid=294300

Move the file to my phone's internal storage
Update via Local Upgrade
Is this correct? Will I still have root after I do this?

You will unrooted after the upgrade as itll flash completely stock.
Just re-roof after it and your good to go!

For my purposes, 9.5.9 and 9.5.10 are good. 9.5.11 reverted something with the brightness and so I don't want to use it.
I found a zip from the OP site for 9.5.9 so I was able to update to that one and since I got root/substratum to work without issue, I'm happy to stay at this build. In my eyes, my phone is absolutely perfect now and I am extremely happy. The only thing I would change is the size but that has nothing to do with the software/OS. Thanks for everybody's help!

I don't blame you, 9511 isn't as smooth as 9510.
also noticed 9510 had better battery life.
