Apologies for opening a new thread for this. I am unable to reply on the dev thread as I have less than 10 posts. So in reference to the following post, I'd like to contribute some experience I had in the last two weeks.
http://forum.xda-developers.com/showthread.php?t=1627689
Across the space of two weeks, I have had a chance to note this symptom on three devices.
Device 1 SGS i9000
Rooted phone and have been on CM9 for as long as I can remember. Wake up one morning to find phone with BLN on, but no ability to wake the phone (power button, home button, volume buttons, nothing works). Popped the battery out, and the bootloop / no recovery went on forever. Had to Odin flash back to Stock 2.3.6 to start again. Since then, any CM9 (nightlies or RC2) attempted always end up in the bootloop, i.e. stock > flash rom, first boot = bootloop. I figured then if I had to go back to 2.3.6, I'd rather go to JB. First JB tried was HellyBean, and the same thing happened. It was only trying pawitp's current alpha CM10 that it worked. Days later reverted back to ICS (Paranoid Android v1.6) due to lags and bugginess.
Important to note, the CWM kernel I have gone through are 6.0.0.3, 6.0.0.8, 6.0.1.0. And Paranoid Android put me back to 5.5.0.4.
Device 2 SGSi9000
Rooted phone and have been on CM9 for as long as I can remember. Phone cut off and rebooted in the middle of a phone call and ended up in bootloop with no recovery. Exactly the same symptom attempting to get the phone back into any of the CM9 roms (nightlies or RC2). Ended putting the phone on Paranoid Android as well.
Device 3 HTC Sensation
Had a lot of trouble trying to flash CM9 on this using CWM. Random bootloop with no recoveries. CWM at that time was 6.0.0.8, which I had lots of trouble flashing Gapps on. More on this device posted here: http://forum.xda-developers.com/showthread.php?t=1786703
And finally, one other observations across all these devices. Somehow with CWM v6.x.x.x I had rather poor battery life. For instance, on CM9 Nightly 07/23, say I started with 100% charge in the morning at 8am, by 12pm, I would be looking at 80% left. Once a week, I will let the phone shut itself down on low power, and charge without switching the phone on. On any other evenings, I would plug the phone and leave it charging overnight, e.g. at 10pm with only 30% left. I have constantly noticed that within a few minutes, it jumps back to 40%, which is rather odd. A 10% charging achieved within minutes is rather unusual.
I have also noted that, when the SGS i9000s ended in the bootloop / no recovery situation, the phone can never be charged. Plugging the phone for charging will the a blank battery icon lit up, with the swirly thing on top of the icon appeared frozen and it stays that way.
Being on lower version of CWM, in this instance, v5.5.0.4., I can observe the units (observed being the keyword here) charges "normally", i.e. no funny 10% charge achieve within minutes. Also, battery life are much better as well, i.e. only 10% drain between 8am (100%) to 12pm (90%).
So, not being a developer but someone that likes to tinker and observed:
- Is it possible that newer version of CWM potentially have some impact to battery life?
- Is it possible that how CM9 is being flashed onto a phone has potential issue? I find it a bit disturbing on an initial flash from stock to CM9, I had to pop the battery out after the flash initially loads a new CWM onto the phone. Then start the flash again with the newly loaded CWM.
I am hoping all these I have experienced in a short amount of time can be helpful to potentially looking into where issue might be. Most people have one phone and tested across different kernels and ROMs. I had the luxury of testing across three devices on a narrower choices of kernels and ROMs.
For the first SGS paragraph I can relate. EVERY ROM would boot loop. I had to flash to stock With repartition ticked. And then flashed semaphore kernel, and formatted system, data and cache. Then I flashed to whatever ROM and was okay.
Also I seem to have the problem with having to pull the battery after a flash to the new recovery. Only happened a few times, but non the less, still happened. Just make sure you flash twice afterward to make sure

Yup, on every occasion I mentioned above, wipe (system/data/cache) are part of the ritual. Just didn't mention them.
I just think the battery-pulling feels rather odd. Can understand why it's needed, but just feel odd. Wondered if it'd be better to keep kernel and ROM separate, e.g. flash new kernel via Odin, then simply do ROM. This might be a 'cleaner' method perhaps? It feels almost like flashing kernel as part of the process is like modifying Windows files whilst still in Windows, then do a reboot.
For now I have fear against v6.x.x.x kernels. But will likely go back to it once CM10 is stable. We'll see.
I installed Eryigit's Android 2.3.6 ROM onto my SGP 5 and have this battery charging boot loop. Are there any solutions for this yet?
Well first things first, I was running a stock Tom lollipop 5.0.1 have a custom twrp 2.8.2 I believe, still have it been having it for a while tried 3.0.2 no difference so I switched back anyways I tried flashing stock rom all of them from T-Mobile starting with the original KitKat rom, I tried the stock 5.1.1 T-Mobile Canadian rom and it worked but it rebooted about every 3 minutes , so after trying many Roms also deleted everything off the phone first through teamwin recovery, I finally got a semi stable Tom which is resurrection remix I have 5.7.0 but had 5.6.9 anyways now it works almost perfect reboots maybe 3 times a day and thats with heavy use, by the way the annoying thing is when it attempts to reboot it gets stuck in the Samsung logo, I remove the battery and reinsert it and it boots like a champ, also if reboot trough os same thing happens, sometimes it won't turn on or take a charge unless I leaves the battery removed for a few minutes about 5. It's gets very annoying have tried so many things nothing seems to fix it and I have 3 batteries so if can't be that and original charger could it be a bad power supply ? I will upload pics in a sec one battery is worse than the other two holds no charge,. Stock rom would get stuck in the T-Mobile logo.

Well for anyone that has tried everything on their note 4 and ir gets stuck in a bootloop but it does power on and reboots very often, i replaced the battery didnt work so i replaced the power switch and that did the trick, no more reboot or bootloop or the phone not wanting to charge
Hello everyone,
I have-or had- MI5 with latest cm14.1 on it, today I downloaded the latest rom from xiaomi.eu -Nougat-. I rebooted into recovery, wiped partitions, flashed the new rom, flashed successfully, and then flashed a font zip, the installer hanged at unmounting system for a long time, I forced rebooting it through holding power button the phone turned off and then never worked. nothing happens, no led when connecting to charger, pc does not recognize the phone at all, no sounds when connecting it. recovery and bootloader does not open. it is completely DEAD. Any help?
same h ere except i didn't get any errors while flashing except the normal command[log] error for all nougat roms. phone is just dead with no signs of life.

I got this error as well,
After some search it seems using a deep flash cable could, I cannot make one currently so maybe you could take a look and try it

I just checked the second post in the xiaomi eu thread
"- NEVER wipe /system partition manually in your life!"
hmm, I have always done this
Edit:
Many people reporting the same issue their.
There's another way to go to EDL mode which is this

I haven't tried it yet as I don't have copper tweezers.

People reported it worked in xiaomi eu thread, gonna try once I have the tools, I wonder why the * dev didn't write "- NEVER wipe /system partition manually in your life!" before the download links

Do follow the videos, i was hard brick 2 times but now it's working
The issue is, you flashed the CM14.1 on low battery, this then messed up the battery reading, while your device showed somewhere like 50% infact it was around 10%, what need to be done is, do a hard reset with power button a few times while connected to a charger, use a new charger/cable and let it charge for a long time, itll then switch on and charge, leave it to charge till 100% then do a full wipe including internal storage and install a new OS

I don't really think that this is the problem because the "rom" flash completely successfully. I don't think that the font flash would cause all this mess. Anyway, I left it charging overnight and I keep pressing power button with vol +/- but nothing happens. Thanks anyway. it seems I have to either use test points or deep flash cable.
Hard bricked the phone with the same ROM here, tried to solve it with the video's testpoints (making contact between the two dots and plugging the USB).
Fortunately, MiFlash with adb and qualcomm drivers recognized the device. So I flashed many fastboot ROMs (miui 7/8 dev&stable) via MiFlash, but none of them made the device wake up. The only signal of life is the led blinking red when connected to a usb.
Still trying...
EDIT: ok, got it booting now. The red blinking led is actually a good sign, it means low battery. I just let it charge for about 20 min and the led changed to yellow, and then I could boot it up.
It seems like in all that time the phone was plugged into my PC usb port for flashing, it didn't charge the battery. So I think we should take into account what Shaky156 said, just in case.

I just revived my mi5 using the test point method, it is rather simple actually.
Make sure you are using miflashtool beta,
I downloaded this rom china developer
I noticed that even though I chose save user data, I still lost my data.

Good to know it also worked for you, I just didn't believe that my battery was depleted from 70% just by hardbriking it...
After installing TWRP it asks to decrypt data even though I did not encrypt, hmmm what now
Edit:
I just did factory reset in TWRP and now I can see sdcard.

I also had my Mi5 die earlier today. Here's what I did to get it back:
1. Popped-open the back cover, removed the screws from the top panel
2. Disconnected battery (left side)
3. Connected battery back
4. Shorted the two contacts at the right side of the board
5. Plugged original USB in
Note that using a deep flash cable is a less intrusive way of doing steps 1-5, but that's what worked for me.
At this point, the PC detected the phone in EDL mode. I then attempted to flash the fastboot ROM for Mi 5, however, I kept getting errors about Missed Hello / Issue with COM port.
6. Downloaded an up-to-date version of Mi Flash (beta didn't work for me), disable Signature Enforcement (Windows 10) and install Qualcomm drivers
7. Downloaded a MIUI 7.5 fastboot rom
8. Flashed, got an error, about storage being not enough... But the screen turned on with the Mi logo. I was finally able to get the phone into Fastboot.
9. Successfully flashed MIUI 7.5 ROM using Mi Flash.
If you are still getting the COM port issue or Hello, try disconnecting the battery again and repeating steps 3-5.
Good luck.

Thanks for the reply, but I already fixed it this way. I used miflashtool beta since the final release did not work.
The problem is did you lose your data after the flash? because I lost mine even though I checked save data in miflashtool

At that point, I didn't really care if I lost data since I didn't have much on it anyway. Nice to hear that you got yours back. Those were dark hours, yes?
Thanks for giving a hope (checking way to recover from video). I'll get proper screwdrivers soon and try do the same.
I have narrowed down the issue, its the nougat firmware thats caused these recent issues. Xiaomi has distributed an unstable bootloader. I highly recommend reverting back to marshmallow firmware and OS

I can confirm that this 100% works for me. You need to be a bit patient with the tweezers and getting the contact points right. It didn't immediately work for me, and I think I had to try a dozen times at least. But eventually it did recognize it. Once MiFlash can see it, you need to use the latest China stable rom. I tried the latest china dev, but it kept on giving errors of missing hello packets.
Hi everyone. I've searched on the web for this issue two days, including this forum and this section. I've tried several solutions altough none has worked. My last hope is your help.
As many of you would know, this phone "suffer" about the black screen issue. Two weeks ago I've upgraded my xiaomi.eu rom as usual (altough from Nougat to Oreo Beta) and after the battery drain was higher than usual, I've found the phone switched off and unable to revive. I then, started looking for the issue and its relative solution, so I opened the phone, unplugged the battery cable, replugged and the phone started as if nothing has ever happened. This week I then update the last rom 8.3.29 (hoping in less drain battery) and the phone did the same. Only problem is that now the cable trick doesn't work anymore.
I've tried to flash many different roms from MiFlash Tools:
- MiFlash_xiaomi.eu_gemini_6.4.21_6.0
- gemini_global_images_8.3.29_20180329.0000.00_7.0_global
- gemini_global_images_V7.5.1.0.MAAMIDE_20160523.0000.23_6.0_global_85fffc8e2d (the one suggested in the "famous" unbricking video on youtube)
I've also run some commands and booted the phone in fastboot, pushed and flashed the twrp (last version) so the pc even show me the phone as sdcard, altough I wasn't able to flash the rom from command line in TWRP (see screenshot).
Anyone has any idea?
Thanks to every soul that could help me through this.

EDIT1: After writing this post, the phone decided to boot (led indicating the level of charge and hardware keys lighting up, phone making sounds...altough the screen remains black. Could then be the cable?
use miflsher and flash official 9.2 firmware
