Hi.
I've been searching for a solution on how to fix my phone for already almost a year now. I didn't even do anything to it, no custom recoveries or OS (wanted to get CM, but at the time it wasn't available on it, not sure if now is).
The problem - the phone is stuck in a bootloop with an empty battery. The battery wasn't empty at the beginning, but it died in the process of trying to make it work, since the only thing I can boot is "fastboot&rescue" mode, in which the phone doesn't charge - how sweet. Now, I've read just about every thread here on how to flash custom (and original) recoveries, all the DLOAD folder versions and everything, and somewhere in between all that I found that it's impossible to flash anything if the battery is low (or totally empty).
The question - how do I charge the battery if it doesn't boot in anything other than fastboot, and when I plug it in the wall it just loops and loops and loops, and doesn't even charge? It's also impossible to turn it off while it's plugged in the charger. WTF, Huawei, really?
Any help appreciated. Cheers,
Can you Boot into recovery through pressing power + volume+?
You may have to remove the back of your phone and buy a new battery. The disassambling process is pretty simple, but of course you will loose any guarantee..

No, can't boot into recovery, only fastboot. If I could, I guess I would've already fixed it, heh.
I actually got it to charge, at least that's what I think. There was a *.bat script somewhere here that was repeatedly doing these two things:
1) fastboot getvar battery-voltage
2) fastboot reboot-bootloader
So, I ran that (while the phone was plugged in my computer and running fastboot mode), and it began looping and looping and looping. Left it like that for the night. Now, in the morning, when I unplugged it and tried to do someting, the red "battery low" LED wasn't glowing/blinking anymore! Since "fastboot getvar battery-voltage" returned an error all the time (remote: command not allowed), I don't exactly know how much power I have in it, but I'll just leave it like that for a day or two now, and then try some of the methods I've already tried before. Got any new ones I could try?
I already removed the back and removed the battery - wanted to see if I can charge it externally, but has a very small connector to connect it to the mother board, and I can't just put it in any external charger - I actually didn't find any external chargers that can charge the battery of this phone, really strange.
About the warranty - don't even care anymore. Somehow I managed to get a small crack on the glass on the back of the phone just a few days after getting it. Screen is not damaged, just the back cover. And, you don't know Latvia, but this is how it goes here. I took it to a repair shop - the one I needed to take my device for warranty repair. However, in Latvia that means it's just an another small repair shop, which just happens to have a contract with the company who sold me the phone (mobile phone operator). So, they take my phone, say they'll do a diagnostic and get back to me. Three weeks pass, and they call me telling that the only thing they can do is replace the motherboard, which is gonna cost me about 250 euros. That, or nothing. I don't agree. That means, if I don't agree to their suggested method of repairing, I have to pay for the diagnostic (about 20 euros).
Well, good idea, looks like you will get your phone running..
To unbrick your device you need to flash a recovery that matches with the firmware you had been on. So, if you had a B1xx Rom running try flashing TWRP 2.8.1.0 and MyRom 1.2. After that flash the stock emui 2.3 recovery and B133 through dload. If you were on a B6xx Ron flash TWRP 2.8.7.0 and MyRom 3.3, then emui 3.0 Recovery and B621.
When you didn't try this way until now, do it. It should work if the device isn't hardbricked.. I wish you the best.

Just flashed TWRP 2.8.1.0, it's already getting better. Now when I tried turning it on in recovery mode, it's not just simply bootlooping all the time, but is stuck on the Huawei logo. At least I hope that's better If I try to turn it on normally it just bootloops again. Omg omg omg.

Well, tried everything again. Flashing all those recoveries, nothing, can't get a recovery. Put a dload folder with update.app in it, magic 3 button combo just gives me some more of that good old bootloop. Extracted everything from the update.app, flashed recovery, system and boot with fastboot - all showed success. I got the most excited when it got to flashing system - it was quite big and took quite long, and returned success, so I really hoped that really did something - but no. Downloaded P7 kernel. Tried "fastboot flash:raw boot P7_kernel" ("P7_kernel" is the name of the file). It created a boot image (544985088 bytes), sending 'boot' returned "OKAY [20.622s]", then "writing boot" returned "FAILED (remote: flash write failure)". Is this the thing that's really broken? The boot flash partition? If so - what can I do, if anything?
God I hate this phone. The best is that I only used it for 3 months, and I still have to pay for it for more than a year. It's been in this condition for 7-8 months already. FML.

Hi. Yes, bootloader unlocked, 100% sure. Have tried flashing the stock recovery, no changes. Tried to find the b135 now - I actually failed to find a real, valid download link! All I found were some russian ****up sites, which downloaded some russian ****ing malware! WTF? I'm about to give up on this phone. Just destroy it with all my hate for it. **** this ****ing piece of **** to hell. There is no hope, and **** my life. Whatever.
Be patient. I'll give you link soon but give me answers for this questions.
What was yours last valid ROM ?
Dude you can't flash any recovery you want.... It's not simply working between different ROMs.
Second question. Do you unplaged usb cable before flashing ROM by force update (3 buttons) ?
PS
I am not sure but battery isn't charging even fastboot mode or if totally device is off ?

My last valid ROM is the only one I ever had - EMUI, whichever was the latest about a year ago.
After flashing recovery in fastboot mode, I unplugged the cable and pressed the power button and helt it until it turned off. Waited for a minute to see if it doesn't turn on, to make sure it's completely off - just what the instructions say. Then I tried the force update with 3 buttons, cable unplugged. With stock ROM it was still bootlooping, no changes at all, but with TWRP 2.8.1.0 it got stuck at Huawei logo - but no bootloop. Just Huawei logo, nothing else.
Battery is not charging in fastboot mode because that's how it is on all phones. But it's also not charging when it's totally off, because when I plug it in the charger, it automatically tries to turn on, and starts bootlooping. It's impossible to charge it then. However, with the .bat script I guess I have solved the charging problem - at least the red LED doesn't light/flash anymore.
Emui 3.0 beta release was at the end of 2014, official B609 in January 2015. It's important what rom you have been on. Trying different ones is just a waste of time..
You may try to extract and flash Bxxx part for part (depends on what rom you were) and then TWRP 2.8.1.0/2.8.7.0.I have no other idea, unfortunately.
It's a stupid question, but did you, when trying to boot into recovery, press volume+ for a longer time?

Than you probably have EMUI 2.3 ROM version.
Try flashing B135 recovery from here.
Next try to install B135 ROM from this link.

No, it broke down before EMUI 3 came out, then. I guess I had the ROM which was just before EMUI 3.
Usually when trying to boot into recovery I press the volume+, hold it for about 10 seconds, and then press and hold the power button until it starts turning on. Then I hold both of them for some time, then release the power button but keep the volume button pressed. I've tried doing it differently - holding both buttons for longer time, releasing both as soon as it starts turning on, nothing I've tried works.

B135 recovery
http://forum.xda-developers.com/ascend-p7/general/trying-to-update-rom-1-2-t3222485
I uploaded it couple days ago...
OK, I left it "charging" for 2 days straight, hoping maybe battery was too low to flash partitions or whatever. Just wanted to make sure the battery is charged enough. I can't check the voltage or the percentage, because "fastboot getvar battery-voltage" always says that it's forbidden, no permissions, whatever.
So, I left it to charge for 2 days, and now I tested all the things you guys have posted here. Carefully, one by one. Every fastboot flash command returned success, but in the end nothing changed. Doesn't matter which recovery and/or boot I flash, it's just stupidly bootlooping all the time. Nada.
Finally, you can buy a defect P7 (with a broken screen or anything like this) for pretty low money on eBay and change the motherboard.
But I could also understand it well if you just throw it out of the window.. You had really bad luck.
Probably i have the same problem..... You solve yours problem with this ?
Nop, didn't solve the bootloop. I managed to get a donor phone for 55eur though, which had a bent body and wasn't functioning well because of that, and the screen was a bit cracked too. So I did a motherboard swap. Worked perfectly, but the battery connector protecting case screw doesn't hold in anymore, so sometimes it just turns off because it loses connection, or something. I tried to fasten it with some duct tape, hoped it'd help, and put a hard case on it - got better, but still fails sometimes.
I try give it back on warranty, i hope thei repair it.
I am in the EXACT same boat as edzjins. I have wasted 4 days of my precocious life trying to flash stuff on a phone with a completely dead battery.
I just doesn't work, period!
The only possible fix is to buy a new battery, replace the old one, and after the new battery is installed, have all of the flashing software ready to go and fired up before the new battery dies, too!
Its a time game.
Just like edzjins, there was a brief period of time when I thought I could stop the bootloop via TWRP recovery, but was unable to and the battery completely died.
Be wary of trying to flash "EdXposed" framework with TWRP. Instead, flash it only through Magisk.
I have learned the hard way : (
Hello everyone. Well, as per the title, after I flashed a new custom ROM (Ivan's AOSP to be specific), my Mi3 refused to boot properly and get stuck in the bootloop at the Mi logo and it would bootloop again and again and again....
Now, if I tried to enter twrp recovery by holding power button + volume up, it would refuse to boot into recovery and just bootloop again. But, I was able to access fastboot mode (don't know why but I could easily boot into fastboot mode)
I downloaded stock ROM for Mi3 and tried to flash it via MiFlash and it succeeded but the device would still bootloop. I also attempted to flash twrp recovery via flashboot and it succeeded, again, but my phone would refuse to at least boot into twrp recovery mode, again. Naturally my phone still had the bootloop at the Mi logo, sigh.
I don't know what to do anymore, aside from sending my phone to repair center that might charge a fortune. Please help!

Many users confirmed the same symptoms. Is it possible that the damage caused by "software" since some people of India have visited the service center and asked to replace the motherboard of which cost $150?
Try flashing the phone via MIUI flashing tool as you were able to access fastboot mode

Here is the link for tutorial for flashing recovery via fastboot mode. All commands are same just download the twrp recovery image from here. DON'T FORGET TO RENAME THE IMAGE FILE, BECAUSE ADB DOESN'T RECOGNISE ANY SPECIAL CHARACTER.
what did you do ? I'm stuck in the same situation word by word.
did you solve this issue ?

Seems like the problem is caused either because of this, or your battery's PCB simply fried because of unknown reason, maybe because faulty charger/cable or wrong charge voltage setting by the kernel? Also, seems like most of the similiar case stems from MM roms, including MIUI's own chinese developer ROM.
Some people with the exact same case stated that after replacing the battery, the device worked again, like this guy on iFixit: https://www.ifixit.com/Guide/Xiaomi+Mi+3+Battery+Replacement/50785
I haven't tested it yet on my bricked device (just ordered the battery today), but I really hope it was just the battery. I think fried mobo is kinda unthinkable, since if the mobo got fried, you probably can't even flash anything since the eMMC would probably also inaccessible.
Hi @rxl.noir, urang Bandung?
How much does it cost for battery replacement? I have sent my Mi3 to the seller because it's not even one year already.

Heyaa~
For the battery, you could easily found it on Tokopedia started from 110k, although most of them are shipped from Jakarta. The replacement process is quite easy, you might only need #0 Phillips or any small plus screwdriver, a plastic card (for spudge replacement), and some guts :q. The details and steps are on my prev. post.
I haven't tried to sent it to the seller/distributor, since it might take a long time to get it done.
Just a little update;
I replaced my battery on my Mi3 that have the same exact case as yours, and it finally works. No more short bootloop, no more stuck in fastboot.
I have my rog 2 stuck in a bootloop. I don't really know why in the first place, because I don't like to change and mess around with custom roms. So i've never done that.
The case was that I was watching a video on YouTube and suddenly the touch screen stopped responding, the phone kept responding to other inputs such as the power button and the volume rocker. So I decided to restart the phone. And then it didn't turn on again. Got stuck in a boot loop.
I've been trying to fix it for a long time. But I just can't do it. Nor am I able to see what is happening with the phone. I have used this guide.
EVERYTHING works perfectly, it doesn't give me any errors during flashing or anything like that. Even the program tells me that the rom has been flashed correctly, and even the rog logo during boot, changes (I suppose because it is a version of the rom prior to the one I had.). The fact is that even with that the phone is still stuck in the bootloop. I have tried more things but this is the one that has taken me the furthest. I don't know what else to try. If anyone has any ideas, please tell me.
P.D. Sorry if my English is a bit rusty.
go back to stock and try other rom.
