P8Max DAV-703L rollback to Android 5

Hello,
I recently "upgraded" to Android 6 and I hate it. Not only do I not like it but my phone is very unstable and reboots and random intervals. Battery drain is also insane, lasting only 1 day.
Please let me know how to rollback to previous Android version. I am willing to donate for an answer that works.
Thanks!

1: make sure you have stock recoveries in place (both "recovery" & "recovery2" partitions)
2: have the stock b029 full rom (links available @xda or needrom.com) in the following folder on your sdcard: dload/UPDATE.APP
Make sure this is the extracted file from the zip, not the zip itself
3: power off your phone, press volume down+up+power until you enter eRecovery mode
Happy flashing
In case your phone doesn't recognize the update package, you can download it directly from your phone:
when rebooting, ensure your phone is plugged in via USB to your PC

No luck, bro. Same as before. Phone checks the file, goes from 1 to 4% and then at 5% (when it says "Installing") it says Update Failed. Reboot now.
Tried with eRecovery also (volume+ and USB cable inserted). It connects to WiFi but can't find any package.
I think the only option is to sell the phone and buy a new one with the factory firmware.

Lol, that's not the only option. Download Huawei firmware extractor, extract boot.img, recovery.img, cust.img, cache.img and userdata.img from the B028 firmware (not b029)(you can skip system.img). Use adb and fastboot to flash those files. After you flashed then repeat the firmware flash procedure with firmware b028 in dload folder and vol- vol+ and Power buttons. Did a rollback several times, worked every time for me.
EDIT:
Also here is a more detailed description:

My phone is pure stock. No root, no bootloader unlock, no nothing. Will this still work?

You need your bootloader unlocked. You can use dc-unlocker to do that. It will cost you 3$ or 3€ and 10 minutes of your time:

Still more convenient that reselling the phone.

I was hoping that wouldn't be the case. But I guess there is no cure for stupidity, since every time I "upgraded" my phones ever since the Galaxy Note N7000 got Android 4, they always ****ed it up, every single manufacturer. They're not at fault here, I'm the idiot who never learns his lesson.
So yeah, selling my phone it is since if you unlock the bootloader, you lose the warranty and that will make my phone sell for dirt-cheap, since I cannot use it with Android 6.
Thank you all for your help but it looks like this is the only option.
The first chance I get (someone makes a similar-sized device) I will abandon Huawei. Hardware is great but the software is utterly horrid! No-name chinese phones have much better software support than they have.

Unlocking the bootloader doesn't invalidate the warranty, so you're good to go. I for myself love the P8 max, hardware and software. The B029 works extremely good for me after customizing it a bit to fit my needs. There is no reason for me to update to Android 6 since everything works so flawlessly.
If you want to keep the size and don't go any smaller, one of the acceptable alternatives is the Asus Zenfone 3 Ultra, even thou I prefer the design of the P8 max.

Unfortunately, in my retarded country (Romania) I have to call Huawei to get the bootlocker unlock code, which by their terms in this ****ty country, invalidates the warranty. I've been through this nightmare before, with the DAV-701L in which I had to call in UK to get an unlock code, which they even said that I will lose the warranty.
These guys ****ed something up because, here's the kicker : you have to get the unlock code FROM Huawei, which invalidates the warranty. But to invalidate the warranty, you need permission from Huawei. **** logic.
The Zenfone is looking mighty delicious, you know. Thanks for the tip!

I must admit that I'm not overhappy with 6.00.
In exchange of a few new feature I lost root and things aren't so smooth anymore. Gonna roll back as soon as I receive my Xiami Max as a backup phone. Asus Zenfone 3 Ultra will be my next buy, but waiting for a phone so long it's a pain in the ass.. they shouldn't announce models months before they can release them. Like HP Elite X3 (January and just coming to shops) or LeTv X910 (which never saw the light) ?

hi guys,
I apologize for resurrection of this thread but does anyone know the location of the stock b029 full rom file ?
I do remember I was running MM and I want to give my P8 max to my niece but unfortunately it's missing OS.
I could install twrp and I was searching for the file but the links are dead and I think this would be the best place to ask.
Anyway, thanks in advance and sorry for bumping up 2 years old thread.
Peace

That's the version I'm have on my device. Want to be able to recover from my experiments. Thanks.

i have no idea what RUU is (it's been too long since the last time I have an HTC phone), but I am guessing it's some sort of a ROM package for HTC devices.
I bought the U11+ from a vendor in Asia, but I can't seem to find the originating country where the phone was sold. I'm unsure if it's a Hong Kong model, or European model. But inside the box, the power adapter that came with the phone is a type C (commonly used in Europe). On the box, it seems the model 2Q4D100.
Now my actual question is, how can I update my phone to the newest ROM because my phone is currently running version 1.10.400.23 (October Security Patch)? Also, if possible, I'd like to keep the phone as stock as possible, root and unlocking bootloader or s-off isn't something that I am after.

i think your device europe model update in setting or dowlond here 1.24.401.2 ru version and update on pc

What software do I use to update on the PC?
Thanks for your response.
EDIT: answering my own question
If your phone is untampered/unrooted, with its bootloader still locked (e.g., you haven't done anything to modify your phone); then IF you manage to find the correct RUU file that matches your phone's CID/MID (CountryID? ModelID?):
1. Rename the RUU file to correspond with your device's model type (e.g. 2Q4DIMG.zip)
2. Find a MicroSD card, and place the RUU file into the root of that MicroSD Card. Insert the MicroSD card into the phone. You need to use a MicroSD card, otherwise the next step won't work.
3. Boot into Download Mode, by pressing and holding down the 'Vol Down + Power Key while the device is turned-off. Let go of the keys as soon as you feel the device vibrates
4. Once your device successfully boots into Download Mode, your device will ask if you'd like to flash the RUU file. Proceed by pressing the Vol Up key.
5. If your RUU file matches your device's CID/MID, then Download Mode will proceed with the installation.
6. ????
7. Profit?

1.24 only OTA'ed in the last few days, so he was probably on the latest on 1.23.
Can always RUU to 1.23 and OTA up to 1.24, so not too massive if you cant find an RUU for 1.24 yet. I havent seen 1.24.709.7 RUU floating around yet.

Hi guys, i am planning on buying the U+ here from China/Beijing, as you know devices here don't come with Google play store and Google stock apps installed. I am wondering since i never owned an HTC phone before, is it possible to flash another country or region rom for ex: HK that has all Google apps and do you recommend me buying this phone?, any further advice or tips would be much appreciated.
I am planning to sell my Iphone 8+ and get the U+ instead.
Thanks in advance.

I have the device for almost 3 weeks now... I'm absolutely happy with it... Don't believe in many of the reviews out there (YouTube etc.)... There are many reviews saying the screen is too dark... That is absolutely not true! I've had the HTC 10 before and while having both devices side by side with same setting, the u11+ indeed looks much darker, but it seems, the lightsensor is much better! In sunlight the u11+ is much better readable than the 10 is... And I'm using just 25% brightness outside in automode and on the 10 I have to use 50+% to be able to read something on the display. What I try to say is, that many reviewers are doing device checks indoor... You don't need your device to be a supertrouper indoors to be clear. So the reviews are dumb. The materials used are absolutely great, the manufacturing is perfect!
So for you question about the Google apps... AFAIK you can download every Google app and install it via playstore. To get playstore itself, check apkmirror.com
Theoretical you can flash other Roms... Practically atm its not possible, cause there aren't any custom roms around yet. It's possible to open bootloader via htcdev site and you can flash custom recovery and root your device. So if you want to flash a Rom from a different region I guess you first need to get s-off, which is also not available now. But with the option to download and install all Google apps (if that's everything you need) from apk mirror I doubt you need to do manipulate anything in the device and just use it out of the box getting all your stuff you need from the web and install it.

Thank you very much for the advice, see the problem with phones specific to china they don't come with Google services framework and Google Account apks pre built, which are essential for some Google apps to work properly or you would get the force close issues which I see alot of users from China and outside are complaining about after installing manually both apks mentioned and other Google apps on the U11+.
I used to own a Huawei P8 (Great device) but i didn't buy it from China it came with Google apps and wasn't facing the issue I am inquiring about. The point I want to make is that the downfall of that device and these Chinese brands is the updates frequency and lack of developer/rom support.
What I am afraid of with this device besides the updates frequency, lack of developer/rom support is not being able to flash stock roms with Google apps pre built. All of these are red flags to not buy and enjoy this nice device which is a shame.
I think it would be a better decision to stick with the iphone 8+ for now because it retains a better second hand value compared to the 11U+ if i decide to buy it. My true device goal is a 2018 device with better looks/specs and support.
Thanks again.

I need to rollback (Honor 8), HELP!

I have a seemingly stupid but still annoying problem. As many of you know Android 8 + EMUI 8 came out this summer and I have updated my Honor8. Everything works well, even better (especially with regard to the battery) apart from a problem, quite annoying. I have seen that everyone around complains about the same problem, so it is clear that both a build bug and not a local problem.
Basically ... the bluetooth link with the multimedia system of my car doesn't work as it should, while it worked well with the 7.0.
Tracknames, music infos disappears, sometimes it connects regularly, starting the music, sometimes nothing happens, sometimes the music passes from the car speakers to smartphone (!!)... in short, manage the music in the car It has become a big problem!
I tried all possible options; reset pairing, reset bluetooth, clear cache, activate the developer options to control some low-level aspects of bluetooth, and finally installed Bluetooth Auto Connect which also has several advanced options. Nothing works. In the meantime an update of 8.0 has been released (mine is the buiold 521). The update came out in September ... maybe (MAYBE) this update fixes all bluetooth issues (but i don't have any detailed info about). Until today I have not received any updates and normally I check new version regularly every day. At this point I decided to return to Nougat!
And here the adventure begins!
I CANNOT IN ANY WAY do the downgrade.
What I tried:
- through HiSuite. The "back to previous version" option appears random (rarely); normally the program tells me "the system is up to date". Once appeared I tried to run the procedure, but after the decompression it gives me an error "error updating".
- by standard Rollback procedure. Using a microSD and putting the full version of Nougate in the dload folder. The installation starts but stops almost immediately with the same "update cannot be applied" error.
At this point I am desperate. I cannot update Oreo, I can't go back to Nougat and meanwhile the bluetooth still doesn't work with my car. Remember that before Oreo, everything worked very well!
What can I do? Can you help me?
Thank you

The more you know...

Finally I've decide to try updating to 8.0.0.562. After a month of tries, fails (damn Huawei and his stupid update system), errors and a lot of other stupid things, I was finally able to update my Honor hoping the latest version will fix all the problems. It was a enormous waste of time (searching around internet)... but in the end I found a method described here: https://forum.xda-developers.com/huawei-p20-pro/help/p20-pro-bricked-t3868085#4And if you go ahead you should find the correct firmware link (on a Russian site). Although, IMHO, failing with the classic method was due to the impossibility or some bugs in the update system, to unpack the update files on sdcard. So the solution seems to be to leave both the zip and the unpacked folder.The problems with bluetooth remain, but I hope that now there is not to be crazy applying next updates. ATTENTION: the method above is NOT valid for rollback! If you try, you'll brick your Honor.
And finally I've taken an important decision... for me this is the last Huawei/honor device. Next time I'll go to another brand, with a serious update system.

Any way to unbrick a P40 Pro? "Your device has loaded a different operating system"

So like a dummy I flashed the wrong firmware on my P40 Pro. LGRP6 instead of LGRP4. Now when booting it says "Your device has loaded a different operating system" and then goes straight to erecovery. In eRecovery, downloading and restoring the system doesn't work because it fails to retrieve package info.
I already tried everything possible with HiSuite Proxy, too. I read bricking a P40 Pro this way requires to replace the motherboard, but not sure how true that is. My phone is still under warranty, but I'd prefer to fix it myself, if possible.
Any ideas? Thanks.

Tried eRecovery without any sim card in it?

Yes, I just get retrieving package info failed. Every time

Then it seems motherboard replacement is the only known option left.

Same issue with me

I spent a month to fix it and didn't find a way.
I tried Chimera Mobile and it didn't helped.
The only thing that probably can help is SigmaKey software. If anybody has it please check and say did it helped or not.
Huawei don't want to replace it by warranty for me, that is why I try everything.

I can't find anybody with SigmaKey. Probably I'll go to replace the motherboard in the nearest future.
Other methods definetely don't help.
Do you have any update? Please share if yes.

Hi all! My device is finally fixed! It was fixed by disassembly, hardware testpoint and flashing of Android 11 via SigmaKey!
You have to find a very expirienced person to do this work. I can recommend one person in Moscow, Russia in private messages.
Disassembly is probably necessary

Thanks for the update!
After 4 days trying everythingI found also a guy who told me exactly what you are saying. disassembly is required because of the test point. No other way currently.
SoI will go to a phone shop tomorrow to disassemble the back cover of my P40Pro+. Then the guy will do the whole flashing process via remote. But it's paid service for 30$. I decided to do or because I wanna use this phone.

The only other way is to try to replace the motherboard by warranty.
However, in my case Huawei refused me this.
I think 30$ is a good price because it was very difficult for me to find a person good enough to do it.

Hi guys. Just posting a small update here. I found a xda user who accepted to help me unbrick my P40 Pro for a donation via remote desktop. He will be using paid tools and hopefully it will unbrick the device. I'll post another update soon, to let you guys know the outcome. Fingers crossed!

It is not always possible without disassembly. (Like was in my case)
I wish you good luck but be ready for disassembly.

Another update. First of all big thanks to @oslo83 for accepting to help me with my bricked P40 Pro. Unfortunately things didn't go our way and the device is still bricked. The problem is that I flashed LGRP6 EMUI 11, with EMUI 10.1 preload & cust. A ****ty situation but it is what it is. @oslo83 advised me to take the device to Huawei repair center (it's still under warranty) and that's what I'm going to do.
However if anyone has a bricked P40 Pro, I still recommend oslo83 services, there's a chance your brick is different from mine and that he will be able to unbrick it. If not, he will issue a refund like he did for me.

Hi guys, I have a brilliant update for you guys:
The guy I was working on this issue was able to fix my phone remotely with SigmaKey. After hours of tries he made it!
There is no software solution yet - so the back cover has to be dissembled. I went to a phone shop at the corner and let them open it. After removing ca. 10 screws you can reach the "Test Point". There are some videos on YouTube which can support you. Its not easy but its makable.
The genius guy gives a step by step instruction what to do via WhatsApp.
So at the end my P40Pro+ works again and I am so happy! I will start the downgrade now (to install gms)and I will DEFINITELY use the correct FW this time
I can share the contact - send me a private message.

Another update hopefully the next one will be the FINAL one.
So like @oslo83 suggested, I contacted Huawei via chat on their official site. They accepted to repair my device for free with no problem. I sent my phone to the repair center and now I simply have to wait. The person in the Huawei chat told me it could take up to two weeks. And another thing, they let me know the phone will be updated to the latest firmware, so I probably won't be able to downgrade and install GMS, unless there is a way to install it on EMUI 11 (not sure). But at least I'll have a working P40 Pro again

I have the same problem. I'm tryingto fix it with hsuite proxy and the phone in fastboot&rescue mod
In HiSuiteConfig.xml I added to be able to enter the recovery mode
<rule type="ELS-N29" cnName="HUAWEI P40 Pro" enName="HUAWEI P40 Pro" option="" ></rule>
I'm testing to flash this:
Base version: ELS-LGRP4-OVS 10.1.0.176
Custom version: ELS-N29-CUST 10.1.0.8(C432)
Preload version: ELS-N29-PRELOAD 10.1.0.2(C432R5)
Checked "Recovery OS", CUST PKG and Preloaded PKG
So far it connects
I can download and unpack the firmware on the phone
but then I have an error-message on (Installing 0%) telling me, that on this phone the recovery mode is not available. I'm trying with different base firmware - but every attempt takes a lot of time.

Update: It's always the same error message after unpacking the files. So now I'm trying to install an EMUI11 rom.
Now testing with:
ELS-LGRP4-OVS 11.0.0.175
ELS-N29-CUST 11.0.0.3(C432)
ELS-N29-PRELOAD 11.0.0.3(C432R5)
Update: Failed to at 0% :-(

It looks like I have flashed the following:
"FirmWare" : "ELS-LGRP4-OVS 11.0.0.170"
"FirmWare" : "ELS-N29-CUST 11.0.0.3(C301)"
"FirmWare" : "ELS-N29-PRELOAD 11.0.0.3(C635R2)"
Still trying to reflash ... any ideas?

I've built now my own dload
using the files downloaded by hsuite over hisuite proxy inside Hisuite\ROM/
and copy them on a USB-C-drive /dload
trying the usb-flashing method. So far it went only to 37%

Question Pixel 7 pro system firmware needed

I don't know if it's permitted or not but I'm in search of the system firmware so if anyone could help I'd be grateful. I know it's unreleased but let's just say I've got the prototype lying around. Thanks in advance.

Doesn't exist. Ideally, you would dump the firmware yourself from the phone.

Now that the phone is released, stock images should be available soon here:
Factory Images for Nexus and Pixel Devices | Google Play services | Google for Developers
developers.google.com

Since Google bricked your phone remotely with the hardware ID (since you got one of the dev models before release), it will be quite difficult to get it running again, a simple firmware flash will probably not do the trick.
And even if you'd manage to get a firmware running, you will not be able to go online, since Googles system has flagged your hardware ID and just brick it again. The only hope you have really is to wait for a custom kernel/OS and use that, IF you can actually manage to flash any sort of data on that phone. Was the bootloader still locked when Google bricked your device?

No it was never locked to begin with. Does this mean even original stock firmware( when released) won't work?

That is highly likely, but don't let me stop you from trying. Maybe you will have success. Also keep your eyes out for the Android Flash tool or the Pixel Repair tool, once Google updates them for the P7 Pro. Big companies usually not have all the tools interconnected, so chances are that the Repair tool won't check for blacklisted hardware IDs, it's just important that under no circumstances you may connect to the Internet with that thing, IF you manage to get it running and as long as it runs stock.
