Hi everybody
Wishing to sell my Huawei P9 I wanted to return it as it came out of the factory but impossible.
It has the bootloader unblock, FRP lock at one time it was unlock and since I tried to make an update it went into lock and the TWRP recovery of installed.
It is under 5.0.1 and android 7 and the number of buils is EVA-L09C530B284.
I tried the 3 methods to install an original ROM of my operator but nothing to do that does not.
- The DLOAD method: it restarts in the recovery twrp there are steps that are done and then it failed all in 2 minutes.
- The forced update method: that's 5% and installation failed.
- With hi suite: everything is going well and said that such is up to date and restart nothing I'm still in the old versions.
I did the 3 methods with the unrooted phone.
I feel that it is the recovery twrp that blocks the installation.
How to install the original recovery and install the official updates?
Thank you in advance for your assistance.

Sorry, I don't understand your question.
For both HWOTA (first link) or HWOTA7 (second link) you need to unlock Bootloader first - but you wrote above that previously you had unlocked Bootl8ader, hence you can use the same Bootloader code - it is bound to your eevice.
Asvdescribed in HWOTA instructions, installation of some stock ROMs will automatically relock your Bootloader (it-sa flag in the update.zip, out of your control) - hut you can always unlock it again.
ok it's good I just made an update and everything is back in order it is as if he came out of the box
thank you very much

Hi,
Device: EVA-L19
Short background: I need to return the phone due to hardware problem. Color camera won't focus and I believe this is a hardware issue as I've tried flashing a different ROM. The problem is I have rooted my phone.
I tried the SRK Tool to relock the bootloader but after I reboot it just gets stuck in recovery mode doesn't even boot to system.
Is there any website I could download the stock rom for EVA-L19? Is there any guide in which I could refer to reverse all the things I made (bootloader, unroot, etc)?
Any help appreciated. :good:
Thanks.

There are a lot of threads, discussions and guides here on XDA
First of all, you must know which cust cXXX and build bYYY you are looking for your L19, installations can differ
You can install FirmwareFinder app from Google Play (there is also a thread here about), from that app you can download particular ROMs
Generally, if you just rooted your phone, you should unroot (depending how did you Root it) and then you can reinstall the same cust and build (to clear all records of rooting) - use FF app, FullOTA-MF-PV versions can be easily installed by DLOAD method (which is described elsewhere in Huawei P9 threads)
At the end, you will probably also need to re-lock bootloader - for rooting, you should have installed TWRP, and for that you needed unlocked bootloader and FRP
To revert, best follow/ask in the threads you were following when rooting etc
Hello,
I have a P10 with TWRP, rooted and bootloader unlocked. Now I Received new version.
My current is VTR-L09 8.0.0.373(C02) and
new is VTR-L09 8.0.0.378(C02) - there is face unlock feature.
Probably because there is TWRP normal(automatic) update doesn't work. After restar process jums into TWRP and doesn!t continue.
Question is how to install?
Doesn!t metter If I lost unlock, root and all. But how to revert to stock(new) version?
I am expecting that comlete instalation is downloaded in phone, I have current new struture(download) inside:
New folder(files) are in:
\data\update\HwOUC\140830\
update_data_full_public.zip 87.66MB
update_full_CTR-L09_vodafone_default.zip 921.22MB
update.zip 2.00GB
\data\update\HwOUC\updateauth\
update_auth.sa 1.45K
the structure inside the zip files is not normal as we have for twrp flashing.
Any hint, idea, how to do this?

The version that is intended for me(unlocked, root, twrp) doesn¨t work. And there is no additional progress from developer.
Any other idea how to update unlocked phone to new version?
you have to simply re flash the original recovery (to replace TWRP)...then you do the update then,re flash TWRP
Hi,
Can someone concisely give the most up to date instructions on how to root the P20 Pro
Confused because some people talk about debranding first? Is this necessary if you, like me, just have a generic non-network branded phone?
Also.. Does rooting require twrp?
A bit unclear on if I should use the offical or unofficial twrp methods.
And if so does twrp prevent OTA updates? I was lead to believe that any OTA updates would simply wipe any root and you just have to go through the steps again, but would twrp prevent an OTA update in the first place?
What are the best instructions to root the P20 Pro to keep the OTA updates going (even if you need to reroot after each update).
Thanks heaps in getting through the confusion!
Here you have manual to root in simple 4 steps. You need adb and fastboot on your computer, bootloader unlock code and Magisk from link in post
https://forum.xda-developers.com/hu...de-how-to-root-debrand-remove-retail-t3788326
Does any of the steps,
1/ unlocking the bootloader
2/ debranding
3/ installing TWRP
3/ rooting
Wipe the device?.. I'm assuming yes?
Also. What's the point of debranding?..
I think I'm on a generic P20 Pro that wasn't bought from a carrier - so is that step necessary for me.
Thanks heaps again for the advice - coming over from the Samsung world and maybe I'm so used to the rooting methods there
Also do any of those steps prevent OTA updates?
Or is there somehow to still use OTA updates but simply need to reapply root on every occasion there is ah update?

Unlocking the bootloader will wipe your device. The other steps won't.
You need to have TWRP installed in order to be able to flash Magisk (for Root), and no you don't have to rebrand if you don't want to. You'll still be able to receive and download OTAs but if TWRP remains installed on your phone it won't be able to install unless you change back to the stock recovery. However there is methods to update with TWRP and you'll be able to get and install updates quicker than waiting for them to be pushed to you phone. That's the main reason people rebrand because generic European models are getting updates the fastest.
What's your device model and current firmware version from 'About Phone' in settings?

Thanks heaps for the advice - makes sense now!
I'm using the model CLT-L29 on C636 which I think is the Asia Pacific model.. And incidentally just received a OTA upgrade to the 128 firmware
.. So in order to receive OTA updates you simply have to change back to the stock recovery after using TWRP to install magisk and root?
But I imagine every time the OTA update occurs it wipes root?.. Which would mean reinstalling TWRP to regain root and doing the whole process again every time?

Yep you got it in one lol
The other option so that you don't have to flash TWRP then back to stock recovery each time is when you receive an OTA is download the same firmware (Full-OTA version) from Firmware Finder - you would just need the update.zip - then using Huawei update extractor you can extract the ramdisk.img Then copy the ramdisk.img to your phone, use Magisk manager to patch it then copy it back to your PC and flash it via fastboot. But I think this is more work than flashing between TWRP & stock recoveries haha
Hi everyone! I recently bought a LG G6 H872, which still has 10e installed. After crawling the forums for a bit, here's the sequence of things I wanted to do to it:
1.) Update to 8.0 Oreo via OTA.
2.) Unlock bootloader
3.) Root and TWRP using this: https://forum.xda-developers.com/tmobile-g6/how-to/root-h872-to-including-11g-t3775518
4.) Magisk
Is the latest Oreo update the 20a version that is mentioned in the thread or should I manually update it to something older. I saw that there was anti-rollback so I don't want to update too far. Also, if there is ever another OTA, how does one update the rooted phone?
Edit: I wrote up some steps if it helps you on this post: https://forum.xda-developers.com/showpost.php?p=77513501&postcount=4
I do not believe there is currently a way to root the T-Mobile versions.

That is not correct, see: https://forum.xda-developers.com/tmobile-g6/how-to/root-h872-to-including-11g-t3775518
For future people who come across this thread, here are the steps I took to root this phone:
1.) Factory reset and then update device via OTA incrementally until 20a (which is Android Oreo 8.0)
2.) unlock bootloader: https://www.youtube.com/watch?v=EpaW0-8-QKY
3.) root device: https://forum.xda-developers.com/tmobile-g6/how-to/root-h872-to-including-11g-t3775518
Note: there is a video tutorial here: https://www.youtube.com/watch?v=-z4CWLikPcI&t=821s. The first steps of flashing the laf partition are very useful to watch before attempting
4.) Factory reset in TWRP
5.) Reset after encryption error, then wipe with TWRP. May give mount error.
6.) Boot into Android Oreo. Device is not yet rooted at this point.
6.) Flash MAGISK via TWRP (SD card or ADB push) ]. Ignore the mount error. Reboot.
7.) Device is rooted! :good:
That's interesting
Without getting into an issue those steps look slightly different in order than the original process.
Or I'm a dumbass and somehow got it out of order. Seems ok now though.
Hello there!
I want to ask if it's the same to do the steps with 20e ?
Curious as well if this works with the latest update.

This is an already rooted version of the latest update. I've downloaded but haven't flashed it yet, but the op is good and I've never had an issue with his work.

I succeeded in completing the process.
Permanent unlock from Tom via app.
Unlocked bootloader.
Twrp installed to recovery, can boot to recovery via low volume/power button combo.
Magisk installed.
20a working nicely.
I'm getting requests from Tmo to update from 20a to 20d. Is this recommended? Will twrp, root, unlock, etc. be lost?
I am glad to see that the bootloader gets unlocked easily. @alliance1975 how did you go from Unlocked bootloader step to Twrp installed step? That is the big one I think.
There is a good TWRP available, but we can't install it because the phone lacks fastboot commands. Is there a way to install TWRP? Or is it really that the only method is the rather risky runningnak3d method?

I used the procedure summarized in step 3. I agree it is risky, well, the riskiest root & twrp I've ever tried. I neglected to say I only read instructions, the dev who actually came up with the plan deserves all the credit.
When I try to oem unlock nothing happens. What can I do? I have followed all other instructions.
Follow steps from this https://forum.xda-developers.com/tmobile-g6/how-to/unlock-bootloader-tmo-t3578099
Yeah I got my bootloader unlocked

You said you successfully downgraded?
Then you didn't need HiSuite (and TWRP) - just WiFi and SIM card to start receiving OTA back to Nougat
And no need to open new thread each time
What was exactly full model/cust/build name from Settings/About of your running system (you didn't provide it in the first thread before downgrade, neither now?!
Flashing TWRP, downgrading/upgrading and now unbricking (?) depend on that - did you downgrade and had it working EVA-L09c432b182 or what?
And TWRP for MM is different than for N

Android 6 doesn't mean anything for your question why it doesn't upgrade to Android 7.
And again, you are not answering what is the full build name (incl cust) and number of your build as in Settings About - but if you don't mind about reading it...
If you are sitting on eg c900, you will never ever receive any upgrade.
Also, for OTA you must have WiFi but also a valid SIM card.
