Hi!
i have this HTC Desire 820u device that had some problems and needed a system flash.
when i dug into flashing it , i realized that actually no flash tool actually works with my phone! any efforts to flash this devices was a waste of time.
but one day i came up with a simple solution! using others TWRP Backups!! I managed to find a kitkat backup but it cannot be updated to 5 or 6 since the rom is not exactly made for my device. so if anybody could give me a backup i would appreciate the help:crying:

I finally managed to install Android 5.0 Lollipop on my Nexus 4.
First I flashed it using the factory images and fastboot and it was working fine, but after one week the sensors did not work anymore. CPU-Z showed no avalaible sensors. So I tried to reflash system.img and then the misery started. I was not able to boot, having the 4 spinning dots for hours, even over night (~8h). I tried every combination one could think of, e.g. installing the factory image, sideloading the OTA, installing flashable zips of the stock rom, I also tried custom roms and formated and also erased every partition using "fastboot erase ... or fastboot format ...". Literally nothing worked except installing the Android 4.4.4 factory image. So I ended up having a nandroid of Android 4 and from time to time installing Android 5 which did never work.
Today I was using the file manager in the TWRP custom recovery and I thought Android 5 not booting may be due to the encryption I had, when Lollipop was running well, the next thought was to try to reset the phone to a "real" factory state, because factory reset in recovery may format /system and /cache etc but the rest of the root file system is still present.
After some search I found this tutorial and I am happy to say that it worked and I rebooted my phone twice without having a "bootloop".
http://forum.xda-developers.com/nexus-4/general/tutorial-how-to-unbrick-n4-t2347060
I did it on a Windows 7 laptop and followed the tutorial closely except I did not flash the flashfactory.zip he mentions (the links are down anyways), but I flashed the Android 5 factory image in fastboot. I have a 8GB Nexus, so I did not have to do the part for the Nexus 16GB.
I hope I can help some of you who tried to install Android 5.0 and ended up like me. First thing to try is always a factory reset, but if it does not work like in my case, this tutorial may help. If anyone has any questions, feel free to ask!

Hi there!
I'm flashing ROMs from XDA since 2013 but now is the first time I experience problems. Since I'm new to this forum I cannot ask directly in the according thread, I'm sorry for that.
Just like always (already flashed a tons of phones) I followed the instructions step by step (http://forum.xda-developers.com/moto-g4-plus/development/xt16xx-cyanogenmod-14-1-alpha-t3492274), starting at flashing the modem ("Requirements", Step 2). After that I mentioned that my TWRP noticed my about not successfully mounting /dev/block/... (first block device, don't remember the name) to /firmware. After flashing the ROM and GAPPs the phone stucks at booting (the animated CM-Logo). Erasing all partitions, system, ... doesn't help.
Do I (XT1622, EU-variant, no Amazon) have to flash an other modem file instead?
Thanks advance!
I installed that system today and I can't recall seeing the steps that you are following.
Take a look at the instructions again.
I installed from twrp the following order:
Modem
CM
gapps
And I wiped before and after.
Also I had to have the files on the internal storage for it to work. I got error 1 when I did it from the sd-card.
Hope this helps you
Thanks for your reply, benedictusg!
I actually managed to install the CM14.1 MOD by restoring everything (incl. relocking the bootloader) and then giving it another try. And hooray - here we are! :good:
For anyone experiencing the same or similar problems, here's what to do for restoring the original firmware:

Cheers!
That's great news! I'm happy for you! I'll keep that in mind if I want to downgrade at some time (I doubt it though, because everything seems to work).
Hi M3 users,
I'm a long time lurker and reader on XDA. Now it's time to give something back or at least participate
Following my recent M3 purchase a dugg a bit deeper into this topic and tried to get us the stock recovery for our devices.
I'm not really a dev. I just used the information I found here and in the russian forum where greatslon (thank you guy) is posting his work.
If you find an error in the process please let me know. The files have not been tested in any way. I have no idea if this would even work (encryption and so on).
So I managed to extract the recovery.img file from the chinese rom. This method will also work for the LTE variant.
Maybe @greatslon or @somboons can share their view on the topic or maybe @somboons can even use it in his tool.

Don't quite understand what's this for. First of all, recovery should be the same version as your ROM. I don't know if their mismatch will immediately lead to some malfunction, but some people on 4pda said they should match. Second - stock recovery's functions are limited to factory reset (wiping data, cache, etc.) and installing OTA updates. Without changing OEMINFO (and it's still unconfirmed), you won't be able to install any OTA except those, intented for your model and region, so again there's no need to install a higher version of recovery than your ROM is. But anyway, thank you for the extraction instruction.
P.S. I think there's no need to flash both recovery and recovery2. Recovery2 can be successfully replaced with TWRP and this combination is really great, cause you can launch TWRP by holding Volume Up button only.
And the only reason why you should keep recovery original is that it doesn't really wipe /data - it also creates some files there like custom.bin, containing your regional settings.
Hi Slavon,
Thanks for your highly appreciated comment. @somboons was looking for a stock recovery so I thought this might help.
Your given information are really helpful. I did not know that you could flash TWRP in recovery2 and replace erecovery Handy information.
I'm pretty new to the Huawei structure so always glad to learn something.
EDIT
A lot of good information can be found here: http://forum.xda-developers.com/honor-7/general/dual-recovery-honor-7-t3308398

Giving Back
Benjamin,
I've also been a long time XDA lurker. Most of the devices I have owned were mainstream and thus already had a very active XDA developer community; Even if root had yet to be achieved, there would be hundreds of messages on the topic.
It seems the Mediapad M3 is just getting started. I am a developer of over 20 years, but very little android experience. However, I have recently spent a considerable amount of time (about 50-100 hours) working with the low level ADB protocol source code. And I have rooted and flashed no less than 50 devices, everything from cell phones to Android TV devices to routers.
I'm going to take this device on as my first real dev effort in this arena.
I have a few goals:
1. Get working backups for people that soft-brick or need to revert (including myself).
2. Recompile TWRP for the M3 to confirm greatslon's work, and better understand the process.
3. Release a stock rom that's pre-rooted and cleaned up (not that there was a lot of bloat on my device).
4. Release a custom rom that's not MIUI (perhaps based of CyanogenMod).
Since I have virtually no experience, I am sure these goals are quite lofty and will take some time. But hey, you got to have a plan, and I don't have anything else to work on right now.
Let me know if you want to work on anything together, or if you need any help with anything development related.

Hey hey 0D0A,
I totally agree with you regarding the backups, I think once the first OTA update is pushed for the EU and US devices we have a good and safe way to go back.
Especially the US owners are struggling with greatslons TWRP version, that's the first thing we should tackle after the backup topic is cleared
I will contact you regarding possible work
Best regards,
Benjamin
can flash twrp via fastboot but get error saying and no recovery
hi, first thanks greatslon for doing the work on m3.
i seem to have succeeded in getting stuck and can't get it to boot into your custom twrp. adb on linux was working fine, but no longer. ditto for fastboot just get "waiting for devices" now. i switched to win10 and installed the hisuite app so i can use fastboot but still no adb. so i have tried to flash recovery and recovery2 but when i try to boot recovery i get error "Func NO: 11 (recovery image) ERROR NO: 2 (load failed)."
i then downloaded your custom rom and tried to flash the boot for that still no luck. i can't use adb so i am not sure how to just flash the custom rom with fastboot without being able to get into any recovery.
i did have this all rooted and working with your twrp but kept having issues with dpi and there was an ota update (b003) which wouldn't apply. so i tried to restore backup and it wen't south from there. basically now can't do much other than see the unlock "can't be trusted" page and bootloader.
any suggestions?
Desperately need stock recovery img, not sure exactly what when wrong, but it is stuck in a horrible boot loop. Tried Benjamin's recovery files and they seem to remove twrp and put it somewhat back to normal, but can only access the emui recovery and that fails to load the files. Put twrp back and tried greatslon's ROMs, they load but goes back to boot loop. Wipe and format everything, install my original backup through twrp recovery, it says it works, but again, back to boot loop... at this point I think I'm dead... any ideas, any word on the official recovery img? anything? Help!!
What device do you have? And what version were you on?

Hello, I am unlocked, TWRPed, and rooted, but am trying to reverse all of that. My build number is BTV-W09C128B002. Is it safe to download the stock recovery from the OP for my device? Or do I really need the C128 version?
Hello and sorry for the late response, you would need the matching version for your C128 device.
I may be able to extract recovery from an update, I have to look into this tomorrow.

Thanks! I have been able to use the Huawei Extractor to extract a recovery.img from OTA updates, but have been afraid to try flashing it. It has been recommended to hold off on trying that since that recovery.img is from an OTA and not a FULL update. Any thoughts?
Hello.
Couple months ago i started playing around with my p8 i unlocked bootloader flashed twrp make backup of rom (yes without a stock recovery) and i flash cm13.
And here is my problem i want to go back to stock i can easyli flash my stock rom from twrp from backup but then when i want to flash anything else for example another rom with lower android version it's gettong bootloop i even make full flash (every partiton from same update.app) but nothing still bootloop.
And here is strange part in custom rom i flashed supersu it worked great so i wanted it on my stock backuped rom what i'm able to flash and flashing supersu gives me nothing it booting normali not two or three times and after boot it doesn't see root.
Can you tell me where is the problem? I can still use phone with twrp and stock backup rom but i want go in lower android version and i can't.
Pleas help!
Thank you
Hello dear users and highly appreciated developers!
I reckon I am not the only one who is stuck on stock Pie and would really like to switch to a custom ROM but either don't know how, or aren't sure about it because of all the threads with bricked phones and all that stuff.
If there is anybody who has a complete tutorial/way of doing it - switching from stock Android Pie - January Security Update to any custom ROM, without bricking the phone, losing IMEI, signal etc. would be so kind to share it with us? Step by step would be convenient because there are people who aren't experienced at all with flashing and stuff like that. Especially in these "circumstances".
Very much thanks in advance, any help is much appreciated!

Hotboot latest official twrp using fastboot command "fastboot boot name of twrp.img
Take a backup of efs partition
Wipe system,data and factory reset
Flash the rom of ur Choice
Flash twrp installer by cosmicdan
Reboot>recovery
Flash gapps+magisk
Reboot to system
Thats what i did
And you didn't get any "Your system has been destroyed" messages after hotbooting TWRP or stuff like that?
hot booting twrp is fine, just dont flash it. it mess up everything on pie.
make a efs backup on twrp fist then make a copy of it on your computer.
hot booting to twrp may take up to 30 seconds, dont panic.
@apexashwin
Hey, can you please link me that "twrp installer by cosmicdan"?
Also, if I flash Pixel Experience do I have to still do the steps which'd come after flashing the ROM? (installing cosmicdan's stuff, gapps, etc.)

It's easy to find. Just find it in the rom/kernel/recovery section.
And as they stated in PE OP, it included gapps so you don't have to flash gapps.
I did in fact do what you said and I managed to flash Pixel Experience without any trouble! Thank you very much
