[Q] Can I flash the OTA zip in TWRP?

Finally, the OTA came out. But it's still not available in my area here (Malaysia) so I have to wait for it to come. But I'm a little short of patience here, and while the OTA zip files is out, I thought I could just sideload it via adb. But when I try to make it work, I spent 4 hours facing some adb problems. I'm using Linux most of the time, and I have Android SDK downloaded. It was so troublesome to make adb work. Initially adb just couldn't find my device. So I Googled about it, and did some modifications on the PC to solve the usb problem and finally adb could connect to my device (while in Android). Then I started to follow the instructions to sideload. I booted into TWRP recovery using adb command and just to be sure, I ran ./adb devices again while the device is in recovery. But then adb shows no device connected. Trouble. I thought it's the problem with some drivers so I used Windows to try it again. Same problem again. Then I started to Google about it and found some forums that mention that it only works when I manually boot into recovery (Volume Down+Power+Volume UP). I followed. And finally, it solved it. It was only the first problem. Then I pressed into adb sideload mode in TWRP and started sideload mode. And just to be sure again, ./adb devices, no device connected again. I thought it's some bug in TWRP, I stopped sideload mode, and went back to the main menu of TWRP (where adb once can detect the device) and ./adb devices again. Guess what, it shows no device again. Problematic. I restarted my pc for many times, switching from Windows and Ubuntu for many times, repeated the above steps for many times, but the problem is just so random. I even changed the usb cable but no luck. So I decided not to use adb anymore and I've Googled for just flashing ota in TWRP. But there's just very few articles on it. Most of them are using adb and stock recovery. Some of it mentioned that if custom recovery is present then it shouldn't have to be so complicated but none of them shows how to use custom recovery. And one of them says I could just flash the OTA zip file through custom recovery but no instructions for it. The last one is my ideal method now, but because of lack of references, I'm not sure about it.
In short:
-Nexus 7 with TWRP
-problems when using adb to communicate with my device whether it's in normal boot, TWRP recovery, sideload mode, or whatever
-problem is so random and I cant figure out whats the problem
-tried installing and uninstalling and installing drivers again and again
-I dont wanna lose my data
-fed up
Question:
Is the OTA zip file recovery flashable? I dont wanna mess with adb anymore. It just wont work properly with me. Or I have to wait for OTA to reach me?

Are you completely stock (besides the custom recovery)? In other words, have you made any changes to your system partition? (have you uninstalled any app? removed any system apk? installed XPosed framework? edited any file on the system partition?)
If your system partition is not completely stock, OTA may not work (depending on which file you modified).
If you are stock, yes, you can download the OTA zip file to your device (make sure you get the right one), and reboot into recovery, and just install it from recovery.
According to Androidpolice, 4.4.4 -> 5.0: razor LRX21P from KTU84P is available at http://android.clients.google.com/p....signed-razor-LRX21P-from-KTU84P.5a0f7a47.zip
If your device is the razor, and is currently on LRX21P, you can download this and flash it.

Thanks for answering. This helped me a lot. As I remember I did not modify the system except for xposed which I uninstalled beforehand. What's the worst that could happen if I flash the ota on a modified system?

When you uninstalled XPosed, I hope you opened XPosed app and clicked the "Uninstall" button from there (instead of just uninstalling XPosed app itself). If not, you will need to reinstall XPosed, uninstall from within the app, and the uninstall the app.
(XPosed modifies a file on your system partition - if you use the uninstall from within the app, it will restore the original file. If you just uninstall the app, the modified file will be left on the system partition).
Worst case scenario - the OTA will fail. I don't think it will cause your existing OS to stop working.

Yeah i uninstalled it within the installer app and left the installer installed and hope it will work with lollipop in the future.

cool! (it will almost certainly require a new XPosed app because of all the changes that Lollipop brought, but it won't hurt to leave it installed)
Edit: Just read http://forum.xda-developers.com/showpost.php?p=56748099&postcount=5 - looks like you will need to uninstall XPosed too

October Security OTA won't install on rooted Nexus 5x with stock Android 7.0

Hello. When I bought my Nexus 5X, it had Android Marshmallow on it. I immediately rooted it and flashed TWRP using the Nexus Root Toolkit (NRT) and it went well.
Along came the Android 7.0 OTA and I only had to remove the saved fingerprints and PIN (to make TWRP see the phone as decrypted) I was able to go through the update successfully with that current setup. Of course I had to re-root my phone after that.
But the 46.7MB October Security Update won't install via OTA. I've tried:
re-rooting it with the latest TWRP (via NRT)
re-flashing the stock recovery (via NRT)
but the OTA still wouldn't get installed. I checked the recovery log and it showed this line:

Also why only now am I having problems with OTA? It should have happened during the Android 7.0 update, right? I would like it very much if I could do this without wiping my data. Please help. Thank you.

The update will fail because you have modified /system. Update using NRT then apply root. I don't use that tool so that's up to you to figure out.
Alternatively, update using fastboot and reflash root afterwards. Follow the guide below:

BTW you didn't "decrypt" the phone. It was still encrypted. You just changed the password used to encrypt the storage of the unique encryption "keys", that were used to encrypt your phone, to "default_password", which TWRP knows about and can try automatically to retrieve your encryption keys.

I went away and
Downloaded the OTA zip file
Installed the Android SDK tools, connected my device and rebooted it into TWRP
Then went to Advanced -> ADB Sideload
Then from the command prompt, typed "adb sideload /path/to/OTA/zip/file" and hit enter
It took a few minutes to 100%, then I rebooted my phone and all is well and updated now.
Thank you so much for redirecting me to the proper solution.

Can you share the link for NRD90R>NBD90W, I'm still stuck on NRD90R and don't want to flash the full OTA (I don't want to flash full image every month and run down the flash rewrites).

Sorry for not being clear, but I used thr whole 1.2GB OTA zip file for this.
Was also wondering if there's a simpler way of doing this considering the October update was just ~46MB.

Rooted HTC 10 - cannot mount /system - root incomplete ?

Hi folks,
I need your help.
A few days ago I have received my brand new HTC 10. I updated to latest Android 7 Nougat and began to root remaining stock.
I followed the official guide and unlocked the bootloader, flashed latest TWRP (3.1.1.0) and SuperSU v.2.82SR1 and even got S-OFF by SunShine.
System is up an running and readily booting but...
Fact is I cannot mount /system in TWRP without the option "read-only". When I try to install apps via TWRP I get repeated messages saying "Failed to mount '/system' (Invalid argument) " and usually the apps do not install properly - flashed apps do not show up in the system after reboot.
In the system I have tried to rename a file audio_effects.conf (this is needed to install Viper4Android) in the folder /vendor/etc/ on the device but the folder is strictly read only. Any attempts to mount the folder as RW (using "adb shell", "su", "mount -o remount,rw /system" and similar) have failed. I have tried to gain access to files in the system folder using Root Explorer and Total Commander but the files remain strictly read only. I just get error messages trying to change file attributes, permissions,names).
SuperSU seems to work and according to Root Checker I am properly rooted but I doubt this. Somehow /system seems to be locked and not accessible.
Any ideas what I could do ?
Many thanks for your help ! :good:

Well, I simply flashed Viper10 ROM and the issue was gone.
Feel free to suggest solutions to the problem as somebody else might come accross this thread struggling with a similar issue. I believe the issue was caused by an incompatibility between the latest Android Nougat and the last available TWRP.

No, it's not an incompatibility issue.

Does anyone know what is causing this? I been running into a similar type issue where I get an error trying to flash ROM's. Tried to do a TWRP backup and it failed to back up data. I do a factory reset and data format and it seems to fix some things but still have trouble flashing ROM's. I was able to restore a nandroid but have ran into this issue a few times. I am on Viper magisk.

plz help a noob

I also just recently updated to nougat and when i tried to root using the latest (TWRP 3.0.3-11) it seems I get stuck on a screen with red text that says, "This build is for development purpose only . Do not distribute outside of htc without htc's permission."
I know this is not the original question but was hoping someone with more experience could help instead of starting a new thread :/
Thanks much!

I just ran the latest Verizon RUU and I am still getting this error when trying to flash Viper10_5.9.0_MAGISK. Seems system is not mounting, I don't know I will appreciate any help Thank you.

Add L24 LTE bands to BND-L22 or BND-AL10?

Just got the phone bootloader unlocked (thanks to Wh1t3Rose for the guide) and now need to add the LTE bands from L24. Settings > About says the model is BND-AL10, however, HCU client says it's BND-L22 so a little confused. Can't find any fw in firmware finder for L22 so assuming AL10 is the right model.
Can I now safely use HuRUpdater to flash BND-L24C567CUSTC567D1B344 (8.0.0.344) FullOTA-MF on this device? Or I am missing some steps like rooting / installing TWRP etc.?
Another question - what TWRP to use with HuRUpdater? Would the first one from here work for 7x?
Thanks for any comments!

If you need to change model bands , it takes more than that.
If you do like that , the model number doesn't change and modem bands also stay the same. You will need to do what is referred to as "re-brand" which changes the oeminfo file , then flash the l24 full ota.
Changing the oeminfo. Makes bootloader lock again. But the same key is supposed to still work.
It can be easy to make brick during re-brand
. You should Study the bnd-hwota-eng script to understand the process.

Thanks mrmazak. Is this a viable option of getting L24 bands on AL10?

Found the L24 oeminfo here. Is there a way I can backup the oeminfo from my AL10 just in case I brick it
Maybe installing TWRP and taking a full backup is a better idea but can't find a TWRP img for AL10 Naugat :|

I will look at it tonight when I get home.
I had found good hwota tool with the re-brand script in it. I had to translate from russain and add L24 oeminfo but ithas been used successfully.
I will look at that linked oeminfo and compare to the one I put in the hwota tool.
A search on the 7x main page for "bnd hwota- eng" or similar should show the tool like.
If you don't find Ivan upload again.

Thanks again, mrmazak. I saw your post in the other thread while searching but wasn't sure if there is more up to date information or an alternate tool.
Is it possible to just add certain bands to a model without removing existing bands? The only bands of interest are LTE 12 and 17 that are missing in this. The person doesn't really care about Oreo or Nougat - as long as it works with AT&T

Thanks mrmazak for updating HWTOA. I'll try rebranding AL10 to L24 tomorrow. Don't see a way to just add new bands so rebranding L24 seems to be the only way for now.
BTW, I took a backup of Boot, OEMInfo, System and modem_fw partitions. For some reason backup of Data partition failed after multiple attempts (unable to find partition for path /system and createTarProcess() ended with error 255). Is Data partition important in this case? The phone has no real data or app installed anyway as it's not in use.
Another question - planning to use HWOTA7 since I have Nougat right now but downloaded BND-L24C567CUSTC567D1B344 (8.0.0.344) full OTA - is this ok? I can't find a Nougat version for L24C567.

I flashed from L21C10 to TL10,before that I saved 8 modem files with L21 to him and the emui tweaker from the phone,then I restored it,and I had 4G+,try so.

There is a nougat full it's. It is labeled for Oreo roll-back. But should work for you . It is found as 'bond' intead of 'bnd'. ( Wait, the rebrand script is looking for three files. I will try and adjust the script to not fault out with just two.)
And link is actually in the hwota thread as a downgrade package.
I do reupload most current hwota file yesterday. I found a bug when I did a downgrade. So I proof read through the files again and re-uploaded.
Also added link to bnd-hwota-eng to the guide thread.

Did you do this to rebrand the phone to support other LTE bands? Or just to get OTA updates keeping the same radios? Sounds like latter.
I am trying to get the US radio bands on my AL10 by rebranding it to L24.

Ok, will wait for the updated script. I downloaded rest of the files.
In the oeminfo folder I see AL10C00 img but not AL10C675. Trying to root the phone to be able to copy custom.bin/oeminfo so that I can go back to stock later. For some reason SuperSU doesn't work... will try Magisk now

I have been looking at some ways to edit the script to make it automatically adjust if there is only 2 update files. And it will be easier to just manually edit the one script before you run it.
Add a "#" to the front of line 332 of hwota.sh.
"HWOTA_BND\HWOTA7_BND-eng\hwota.sh"
Need to just comment out the line with "$TARGET_UPDATE_DATA"
Code:

Alright, an update - it went through lot of steps as expected (including installing oeminfo and unlocking the bootloader) but ended up with "software update failed" error on the phone. On command prompt here is the last few lines of the log -
Use the volume buttons to select YES and press the power button

Error for update_data_public.zip was expected and on close inspection I noticed there was an extra '.' in the name of update_all_hw.zip. It was update_all_hw..zip.
So, fixed it and put the phone in fastboot mode and re-ran update.bat. It installed recovery and asked me to put into TWRP. I tried but it never went to TWRP started installing the previously copied ZIP files. It took a while but after it restarted, it went to straight to Android (YAY!). Went to Settings > About and say the model as BND-L24 and build number System 5.1.0.98(07DV).
So far it seemed everything was fine - then I inserted the FreedomPop SIM (uses AT&T towers), added the fp.com.attz APN and restarted it - AND the same issue, can't see the carriers and 0 bars
The oeminfo was definitely installed as I see a lot more options in "preferred network mode" but selecting Global or LTE or anything else does nothing...
Since I am not able to boot into TWRP, I wonder if that's causing an issue. Every attempt to boot into TWRP goes into a screen showing "installing update" with 5% status. It eventually (after 10 minutes or so) boots into Nougat.

Gave up and started from scratch (after installing TWRP img mount manually) and it completed successfully (with expected error for the missing update_data_public.zip). Build number changed to BND-L24C567B150 so both zips were installed yet the problem remains the same - no cellular connectivity and settings > More > Mobile Network > Carrier remains disabled...

Did you do this to rebrand the phone to support other LTE bands? Or just to get OTA updates keeping the same radios? Sounds like latter.
I am trying to get the US radio bands on my AL10 by rebranding it to L24.

It’s just that the L21 is always 4G,and on the TL10 it goes to 3G,I switched from L21 to TL10 because of gestures, now I have 4G+ as well as on L21.

Good catch with the renamed file. You did right thing to start over, because that first build number was not correct.
As far as I know this should have changed the radio files (modem).
I will keep looking for other confirmed way to change the selected bands.

Thanks mrmazak. What could be the reason behind disabled option? Earlier with AL10, I could go inside and see AT&T listed but selecting that would not help as corresponding radios were not enabled in AL10.
Now, even if L24 radios are not properly installed / enabled, I should be able to go inside and see AT&T listed - makes me wonder if all the radios are now disabled.
Is there another way to check what radios are available in a phone by running some app?

Not sure about other ways to check the bands. There are playstore apps that will show what band you are connected to, but have not seen one that shows which ones you can connect to.
side note::: Funkyhuawei (paid service) says of there rebrand guide, that you must flash the new firmware at least 2 times. So maybe take the flash one more time.
some general questions about your problem.
On about phone screen, what is shown for 'baseband' ?
does the imei # number show?
are you installing sim into slot #1 ? (#2 does not support 4g)
did you verify freedom pop sim is activated? (tested in other device)
edit:
found few posts in some "rebranding" threads, that say what you want to do might not be possible.
They say on the software side it will have drivers for the correct bands. But he hardware may not suppport it.

I tried once more tonight but the same result - no service and carrier disabled.

There are 2 long numbers for the baseband - both start with 21C60B. Yes, both IMEIs show and are the same as before.
Yes, I always used the dedicated SIM slot as I have a micro-SD inserted for backup.

I am inclining towards this as well - possibly missing hardware
Now, how do I get back to AL10C675 (don't see a Nougat option in FW Finder) and original radio? HWOTA doesn't have C675 as option, it has C00. I do have the original custom.bin and oeminfo but how do I create a zip to install with TWRP?

[ROOT] [MAGISK] Global ROM on CN Device - WORKING ROOT

THIS IS NOT FOR FAINT OF HEART. DON'T BLAME ME IF YOU BREAK SOMETHING.
Mount system as RW in TWRP. (this took mounting, unmounting, then remounting for me)
Use the following commands CAREFULLY from a computer.
cat /system/build.prop > /sdcard/build.prop
Open the build.prop from the sdcard and edit the following line numbers: 25, 26
You are changing:
ro.product.name=perseus
ro.product.device=perseus
To this:
ro.product.name=perseus_global
ro.product.device=perseus_global
save the file on the sdcard
Go back to ADB session and do this:
cat /sdcard/build.prop > /system/build.prop
IF THIS FAILS YOUR SYSTEM IS NOT RW, UNMOUNT AND REMOUNT IN THE MOUNTS MENU.
Go back to the mounts menu and unmount /system
Flash Magisk 17.3 (18.0 seems to be having intermittent issues with passing checks)
Reboot, and enjoy your CN device running Global with ROOT.

out-file : Could not find a part of the path 'C:\sdcard\build.prop'.
I got that error above. How do i know twrp mounted system correctly?
nvm... i went into advance and did via terminal

Great find, works!!
Thanks!!

You're welcome. I may try to make a flashable zip to do this automatically, but I haven't had a chance to look at it.

Work so well, Thanks @PWn3R!

Here is the clue. " 'C:\sdcard\build.prop'."
What is a Windows drive letter doing on an Android? Adb session?

@PWn3R YOU ARE THE MAN

Has anyone tried a custom kernel on the latest global? I tried androplus v 0.6 and it didnt really work. It allows me to replace files in system but not rename because when I overwrite it still says there is an existing file with same name.
Any kernel that works please let me know. I am working with defcomg to get gcam modded more than the current ones.

I would like to try, i already had install last global, and this rtemove my twrp instead the official recovery.... Can you give me all the steps to do from this position? Thank you

I have a problem with camera, force close no matter what I've done. may be build.prop change?

Hi the change to the build.prop did not break the camera. Mine is working fine. Maybe clear app data for that app?

I do many times, didn't work,

@PWn3R, the root is working but there are some functionalities that disappeared in the setting menu such as slider settings, screen color.
For those who wants to revert to CN rom, revert the changes you have done and DO NOT forget to remove Magisk by flashing the uninstaller zip otherwise the device will bootloop.

I restore the original build.prop and boot.img, the camera came back to work. Any workaround?

I didn't notice if the slider settings were there before changing the build.prop. The problem here is that when you flash magisk it's enabling secure boot, which is triggering a check that normally runs when the device is locked. I think we can probably fix that by modifying the file that causes it and then this will work without build.prop changes. I have not had a chance to look into that, but will try to do so.
