HELP: P2 keep rebooting and never enter system - Lenovo P2 Questions & Answers

First, this phone is converted from C72 to A42 by the seller.
I have enabled encryption and therefore I cannot use the "Fuse wipe data".
It went amok and start bootloop few days ago. I tried cache wipe with simcard and sdcard taken out. It still failed to enter into system UI.
Any idea what went wrong? I have not backed up my data and hopefully avoid hardware reset.
Looking for someone who can help me. TIA.

First of all: My method deletes everything on your phone. But it should work in mostly all cases.
Download this
Extract it, boot phone into bootloader, then run flashall - stock reco.bat and wait until the phone reboots on its own.

[Q] Soft bricked my encrypted phone and I can't factory restore or flash new ROM

While installing the most recent update to my encrypted SG3-L710, the phone restarted and while booting up remained stuck on the blue/white Samsung logo.
-After removing the battery and attempting to get around this several times it appeared that the update had soft-bricked my phone. I was never prompted to put in my passcode to undo the encryption.
-I am able to access CWM Recovery and, being that the only significant thing I would lose are my contacts so I attempted to perform a factory restore which was unsuccessful. It appeared the error indicated it was the /sd_card and /data folders posing the problem.
-I attempted to mount and unmount the /sd_card and /data folders which was unsuccessful, formating them also did not work.
-I downloaded Odin and the PIT file as my last hope. I attempted to flash the stock ROM to the phone and hopefully wipe the old ROM from the system. Odin also encountered problems with the /sd_card and /data and was not able to progress past that point. Now I am attempting it a second time to obtain the specifics and it's stuck on "<ID:0/004> Send lock information...".
Any ideas on how to be able to bypass the encryption and wipe my phone so I can flash a new ROM on this?
I've been working on this problem for almost two days now and I would greatly prefer not having to send my phone into Samsung and spend $100 to do this for me! Thanks ahead of time, bear in mind I'm new to this and might be a bit slow.

Error «Encryption was interrupted and cannot be complete»

Hi Guys! I have a problem, and i really don't know how can i fix it.
My phone boots normally, but when boot finish this error appear in the screen:
«Encryption was interrupted and can't be completed. Phone data cannot be used anymore.
To continue using your phone, you must restore factory settings. After the restoration, you can restore data backed up in your Google Account to your phone»
There is a "Reset Phone" button but if i push it nothing happen.
I have tried to clear data/cache in recovery but nothing changed, I have tried to install a new ROM (i tried a lot of ROMS) but when it arrive to 50% more or less installation fails.
I have tried this guide oppoforums.com/threads/guide-how-to-recover-your-bricked-find-7-7a.23067/ but it cannot work (Image Attachment)
Also FASTBOOT can't work. (For exemple: if i try to flash recovery it fails remote: failed to flash recovery / erase userdata / cache)
I really don't know where can i also looking
Help me please!
Anyone?
I'm having the same problem....
Restoring an old backup woth TWRP results in the same error.....
hi guys this happened to me too,
luckily I had twrp 2.8.6.0 flashed for recovery.
think you should still be able to get into fastboot if you do a battery pull
then poweron with the powerbutton and volume up till you see the oppo man icon.
then you should be able to flash your recovery with the latest twrp.
if you seen the penquin then this may not work for you. As i have not done a hard recovery before so i dont know if it would work.
I saw the oppo man so i was able to fix it by:
booting into twrp recovery,
i selected wipe --> advanced and there was an additional option to do a wipe for encrypted volumes and i selected all partitions to be wiped
then i installed i had downloaded on my SD card, it was ColorOS 2.0.8i i believed and it fixed it.
sorry if i am a bit grey about the details i did it a while ago so.
Actually found this in the cm12.1 nighlies thread
http://forum.xda-developers.com/showpost.php?p=58304054&postcount=14
issue is possibly due to unified partitions

Possibly Bricked?

Hey all. Hopefully someone can provide a little assistance with this..
TLDR; Phone was fine, this morning it went into a bootloop. Tried restore which didn't work, tried wiping which didn't work, wipe everything and installed a new factory image and now it still won't boot and recovery is giving "no command" but I can still see everything with fastboot.
So a few months ago I rooted my Pixel Xl and flashed a "official" 8.1.0 ROM on it along with TWRP and Magisk. Everything was going fine and then about a week ago my phone shut off and wouldn't turn back on. I had to hold the power button about thirty seconds for it to come back. That was the only issue until this morning. This morning the same thing happened, the phone had shut off at some point last night while it was plugged in and this morning it was a black screen. Again, I held the power button down for about thirty seconds until it booted up, but this time a couple minutes after it booted, it shut back off again. Rinse and repeat and every time the time on was shorter and shorter until it just got to the Google boot screen and would freeze up and shut off.
After playing with it for a little while trying to figure out what was going on, I tried to do a factory wipe/reset. That didn't resolve anything. I booted back into TWRP and tried to do a restore, but about 80% of the way through it froze up. I restarted the device and tried restore again, but it froze up towards the end once more. So I tried doing a wipe, then a restore but only the first two boxes checked, system and something else.. It completed successfully, but was still boot looping just like before.
Then I thought maybe it was something internal and did a full wipe of everything.. Still no luck. Then I figured since there wasn't much to lose, I pushed the newest factory image to the phone using platform tools/fastboot.
Now what I get is when I try to start the phone it'll go to the Google logo, then restart, then do that once more and then it will go to a little screen with the Android on his back and an exclamation saying "No command", which I'm assuming is recovery mode since it does the same thing when I try to go there.
I can access fastboot still and all the system menus, I don't care about losing my data obviously and I just need my phone to work. Is there anything I can do?
In the bootloader my information is..

Ok, so I'm assuming you have the latest factory image currently downloaded on your PC and extracted all the files to the same folder as fastboot/ADB. Hook up your phone to the PC and boot into the bootloader on the phone by powering on while holding in Volume Down + power. In the folder where you have fastboot on your PC, hold down shift and right click the mouse and select open command prompt (or powershell, depending on Windows version). Type fastboot devices to make sure your phone is being seen by your PC. If it is, type fastboot erase system, after that runs type fastboot erase userdata, once that runs type fastboot erase system, and finally fastboot erase boot. Then type fastboot --set-active=b , and run the same commands on that slot. Then type fastboot reboot bootloader, and when it reboots to bootloader type in flash-all.bat . That should wipe everything properly on both slots and install the latest factory image. If that doesn't work then I would say there's definitely a hardware defect. Also if it doesn't work I would try a different port on your PC.

Inside of the factory image file, once unzipped there is another zip file contained in there with the same name. Do I need to extract that as well since it has options such as boot.img, keymaster.img and several other .img files in it, or do you just extract the main files containing bootloader-marlin-8996-012001-1808030001.img, flash-all.bat, etc.?

Awesome, thanks for the reply. Question though since i'm not entirely sure about the slots. Since it's already reading it as slot B, will I change the active to slot A at some point or will running those commands in slot B erase slot A, as I understand that it basically works in whatever slot is not active.
It should detect slot A by defualt, but as long as you run those commands for both slots you'll be wiping it clean. Keep in mind we aren't talking about TWRP, we're in fastboot. And no, once you extract the files from the zip you don't need to extract the other file inside of it. The flash-all command will read it and do the proper magic. Just make sure the extracted files are in the folder with fastboot/ADB.
Well, I followed it to a T with your first post and I made it further than before. I got it all the way to where it asked if I wanted to copy files and then it froze. Restarted and it made it to finding my sim before it restarted and then it makes it to a different point before restarting, which is further than I made it before, however it still hasn't made it all the way into the software, so I guess I'm pretty well screwed unless it's something with Slot A. But I'm pretty doubtful at this point.
Update: Now it won't make it past the Google logo anymore again...
Ok, so it still isn't working. I'm going to try flashing the 8.1.0 image in a bit and see if maybe that some how resolves it. Doubtful, but it's my last step before I go spend a thousand dollars buying a new phone..
A couple questions though, when I flash-all I'm getting a lot of "Archive does not contain 'xxxxx.xxx'" errors. Archive does not contain boot.sig, boot_other.img, dtbo.img, dt.img, odm.img, product.img, product-services.img, recovery.img (this one seems important..), super.img, system.sig, vbmeta.sig and vendor.sig are all missing from the archive. This normal?
Also, I can play around in bootloader and I could in TWRP before it was erased for hours with no reboot or anything, but once the OS starts to load or loads, that's when it freezes up and fails. If it was a hardware issue shouldn't it be restarting regardless of what I'm running under?
Just trying to expend all my options before spending more ludicrous amounts of time for a piece of hardware that can just die without reason.

Format failed when doing a full wiping of OnePlus 3

Hi,
I need some help with my OnePlus 3 running the latest or close to latest Android 8 OTA stock rom. It started half year ago, suddenly the phone was in a boot loop. I switched it on and off and I managed it to start again, doing a factory reset and wiping cache data. Then I reentered my details and selected a password. It was working for some days again, but I struggled to enter the right password after a while. Not because I'm stupid, it's pretty easy and I did it again and again. Then it was accepted and the phone was running again. I backuped my data and wiped it again just to check whats going on with that password. After restart I reentered all my data with password 0000. After restarting, it started again having trouble to enter the right password... not accepted. Switching on and off and then suddenly 0000 was accepted.... I don't know, I was tired to use this phone anymore and left it on my desktop.
Now half a year later. I want to fix this somehow and I thought, ok nothing to lose. I try that new Android 9 beta with adb sideload. Before that I'll do a full wipe loosing all my data (no problem). The wiping bar stucks at 99% and then it says "Format failed" with the only option "Yes". So stuck there, not started to sideload so far.
Update 1:
If I select that "Yes", I'm back in that erasing menu, with 3 options factory reset, wiping cache and erasing everything... if I select the last option again, it takes a second saying "Format failed"... I could do this forever. But if I select another option like wiping data something strange happens. It opens up a password screen asking for password... none of my passwords are working there. It is starting to decrypt... but stops with vibration and I'm back in that password screen. Only option that is left is "Forget password". If I select that, it is warning me, that I'll lose all my data. I say "Yes" and it's rebooting with a Chinese screen with a bar stucking at 99% again. That after a while the screen turns black. Phone is rebooting into that Chinese screen again, animating the bar to 100% again, switching itself off. If I start normal, Android logo appears, thats it, no OnePlus circle is coming up. Then I did it once more... "Chinese init/wiping loop" again. So I can restart normally having this or restart in recovery to do all the things as before.
Update 2:
After showing up the Chinese init/wipe loop again it restarted but now with red/white OnePlus circle animation. As you read this, it's still rotating...
Are there any thoughts about it... has this phone a hardware damage or what can I do? I appreciate any ideas.
Cheers, cyx

Try THIS version of TWRP to format and flash.

Update 3:
Before following tnsmani's advice to install TWRP I did something that makes things worse. Because I couldn't wait, I sideloaded the new Android 9 zip without any problems in sideload mode. It was installed and the loading circle was coming up. It took a while and finally the phone switched off. Now the phone is booting up to a new rounded edge OnePlus splash screen without any animation and It's not possible to start the old recovery mode anymore. So I can't connect to adb or fastboot to install that TWRP. All what is coming up are different menus without the options I need. I attached two new pictures to show them. But I can't establish a connection to my pc anymore. No devices showing up.
Update 4:
Ok, it seems that fastboot is communicating when I'm in that green/red menu which says start but my command:
fastboot flash recovery twrp-3.2.3-10-oneplus3.img
fails with the output:
target reported max download size of 440401920 bytes
erasing 'recovery'...
FAILED (remote: Partition erase is not allowed)
finished. total time: 0.019s
Update 5:
Ok, I followed this steps:
https://forums.oneplus.com/threads/guide-oneplus-3-3t-unbrick.531047/
to unbrick the device with MSMDownloadTool and Qualcomm drivers, but with no real success so far. But I can start recovery mode again and adb sideload is working as well.
But with anything else, I have no luck. After a new sideload it's keeps anímating the Oneplus dots and I can't install TWRP to do a clean wipe.
All I want to have is a booting up final or beta stock rom working as before, without any specials.

Is fastboot/bootloader working or not? If it is, simply flash the TWRP first and then proceed with ROM.
If the MSM Download Tool succeeded, you should be able to boot. If not, it means that it did not succeed. Try it a few more times since for some people, repeated attempts are required before the phone boots.

What I noticed from your SS is that your bootloader is locked. So no way you can flash or run a custom recovery til the time you actually unlock your bootloader.
I will advise to unlock bootloader first, flash TWRP fixed version (somewhere in LOS thread is the link), "format" /data partition, flash your desired OOS Rom and then try again and see if it works.
@cyx
Boot into the bootloader and on the PC enter this command: fastboot oem unlock.
This should unlock the bootloader. Then flash TWRP, boot back into it and flash ROM etc.

Unable to decrypt Mi Max 3 - Please help

Respected members of this forum. Please help me. Here is my situation. My Mi Max 3 (unlocked) had fallen into water a few days ago. When I removed the phone out of the water, the phone was still turned on, but I made the mistake of shaking it to get out the water and then the phone went blank, black screen. I was scared that something got shot inside. I buried my phone into a bag of rice for a couple days and when I tried to turn it on, it woudnt turn on even after an hour of charging. I panicked, but learnt that I could use the EDL test point method and reflash the phone with stock firmware. I shorted the test points and used Mi Flash and installed the MIUI 12.0.1 global stock rom which was the version I was using before the phone went out. I had ticked 'flash all except storage'. but I when the phone booted up after flashing it took a very long time to load to the home screen (more than an hour, I suspect due to an encrypted phone which I learnt later while doing some research) freezing up very now and then and finally I was horrified to learn that all my data was erased. Anyways, I was thereafter having issues, cause the phone for freeze for more than half an hour every now and then. I diod a lot of research and learnt about the encryption method that Xiaomi uses on their phones. I then flashed TWRP using fastboot, but when I entered into TWRP it said that my data was encrypted and TWRP was frozen, so I couldnt even format data (and 'fix partition' if that was necessary) as many have suggested on the internet. I tried orangefox recovery which I was previously using, and had the same issue. I tried installed the patched boot image made with magisk (which did not have the dm verity option, only the encryption option which I unticked) using fastboot and it installed, but my phone was stuck at the boot logo. I tried installing the Disable_Dm-Verity_ForceEncrypt_12.27.2019.zip found on the internet using a tool called the "all in one tool" which was able to flash zip files though I had a frozen twrp recovery, but still when I checked 'fastboot oem device-info' using fastboot, it showed (bootloader) Verity mode: true. I have tried various methods but I am still
1. Unable to get my TWRP unfrozen to format data (suspect TWRP is frozen because the phone is encrypted)
2. Unable to decrypt my data partitions
3. Unable to remove DM verity in bootloader.
If I can get TWRP unfrozen, then I can format data, fix partitions or try any methods suggested. I would like to totally decrypt this phone and then install a custom rom. PLEASE HELP.
