MT6572: Infinite boot loop in recovery mode task. - General Questions and Answers

Device: MT6572 'One Touch Pop C1' 4015A
Summary:
I have an old mobile phone that, after doing a 'wipe cache' in stock recovery, got stuck in an infinite boot loop in recovery mode and continued the task of 'formatting/cache...'.
Hello, I was trying to recover an old Android phone that was stuck on the startup logo. The first thing I tried was to see if I could enter recovery mode, and I was able to do so. Then, I had doubts about whether to do a factory reset or just try deleting the cache. Finally, I decided to try deleting the cache, but it caused the problem I describe in the summary.
I tried flashing the stock ROM with 'SP Flash Tool', but even though the tool said it flashed correctly, I don't think it's working because after several supposedly successful flash attempts, I tried formatting the entire flash and the mobile phone still kept booting into recovery mode. Shouldn't it be dead? I also tried flashing a corrupt recovery, but it's still the same.
'SP Flash Tool' connects to the preloader MTK port and transfers at a speed of 15mb/s. Is that okay, or is it a ghost transfer? It seems very fast considering the writing speed of the internal memory.

[Q] Lenovo A1 not booting after Installation of CM 7

hey guys,
today i took upon the task of rooting my first android device and installing cyanogenmod on it. i first installed fastboot and then clockwork for rooting. all went fine then i installed cyanogenmod. after the installation said it completed succesfully i restarted my tablet but now it just stays at the lenovo logo during booting. i still can get into the clockwork mod recovery menu. i already tried wiping data/cache both to no avail. i can also still boot into fastboot when i turn on the tablet and hold the vol+ button but it doesnt do anything.
i really, really hope i didnt brick on my first try, if anybody got ANY clue, i would be more than thankful
ok i fiddled around a little bit more and formatted /cache, /data and /emmc in hope of removing anything that might prevent my tab from booting. after that i got the stock recovery menu again from which i tried a factory reset. however, when the tab tries to install factory data it says it failed. luckily i have an sd card with cwm on it so i can boot into it again.
i think that somehow the files needed for a factory reset are damaged or gone. i will try flashing a new rom when i get myself a cardreader, i just used the a1 as mass storage until now.

[Q] Bricked P5100? Help please!

My P5100 had CM10 nightly on it and was running fine until I upgraded to the latest version of CM10 after wiping the cache & Dalvik cache. After the upgrade I couldn't get Google Play to run even after wiping its data and fixing permissions so I tried to do a CWM restore. Unfortunately there was a fault restoring the Data partition and now my tablet is stuck at the animated bootscreen. If I long-press the power button it powers off but immediately restarts. There is no way to start in in recovery or flash mode. I've plugged it into my PC and the Samsung Android ADB interface is showing but the other references to the tablet all have a yellow triangle in Device Manager. I'm hoping some clever person can help me rescue the tablet with ADB. Thanks!

IF CWM is not working use Odin to flash CWM again then use CWM to flash CM10,
You may need to do a factory reset (full wipe) from CWM.
If all else fails use Odin to flash stock JB ROM

Thanks but Odin cannot see the tablet to re-flash the recovery.
Downlods mode
Then flash new firmware

That's the problem - I cannot access download mode
UPDATE - it just started in download mode! I can manage from here!!
Just for the record you can install adb on the pc and run the command 'adb reboot recovery'. This will force the tablet to reboot in recovery mode.

Jeez, this has taken up most of the day to fix. I came across many problems I have not previously experienced:
1. When the tablet was stuck at the boot animation and I tried to turn it off by long-pressing the power button it immediately restarted. The only way I could get it to turn off was by long-pressing the power button whilst it was connected to my PC.
2. Flashing the stock ROM with Odin appeared to complete successfully but it would never fully boot, it always got stuck at the black & white Samsung screen. Same problems turning it off as above.
3. Flashing CWM with Odin caused the tablet to reboot into the stock ROM which would not load, in the end I had to untick the "reboot" button in Odin, power it off then manually restart with the Vol- & power buttons.
4. The only way I could get a bootable ROM was by flashing CM10 with CWM. I tried to restore 2 previous CWM backups but on each occasion there was an error restoring the Data partition and I got stuck at the scenario at (1). The backups were made to the external SD card with CWM Touch - is the Touch version unreliable?
I would be really interested if anyone could shed any light on any of this stuff!
For how long did you let it install during the first reboot? It happened to me too, and it took about 10 minutes, maybe even more...
Also, did you try in the "Mount and storage" cwm menu the options "format system", "format data", "format cache" and "format preload" options, prior to re-flashing a ROM? I have read somewhere that for a clean install it's better to do this, as it really clears everything that could mess up the system between two different bases ROMs (like CM and stock).
What I do everytime is using in CWM these 4 "format" options, plus "wipe" system, cache and dalvik, then immediately after this I flash with cwm the new "zip" copied on the card. Then the first reboot is much longer than usual, as at this stage it installs the files, rebuild the dalvik cache etc.
Good luck

I think I gave it a good 20 mins to boot. When I got up this morning there was an error message saying that there was no room to install any more apps even though I had very few installed. Settings -> Storage would not calculate the space available so I figured that the partitions had become corrupted. I did the step by step format you described and reflashed & it all seems to be OK now.

[Q] Nexus 5 bootloop

Hi,
I'm trying to bring my N5 to life. It has bootloop on Google logo (sometimes stuck on android animation). When i got it it was stock and unrooted. Computer can see the device, adb and flashtool works fine. What i tried to do:
- erase cache and userdata,
- factory reset
- change recovery to TWRP (tried CWM too, both works)
- flashing the factory images (all from 4.4 to 6.0.1)
- flashing factory image using this tool: http://forum.xda-developers.com/goo...kit-v2-2-kwonggers-nexus-5-one-t2508817/page5
- fix persist partition using this solution: http://forum.xda-developers.com/google-nexus-5/general/guide-to-fix-persist-partition-t2821576 -when I'm doing this, adb see my device and after using these commands I got only something like: clean, 15/1024 files, 1109/4096 blocks, it is not asking my about repair or change anything...
Unfortunately, it still has got bootloop. I can't go into recovery when I'm using usb cable, I can start it only without cable and then plug it in. (When it is on and I'm trying to turn on recovery mode it has bootloop on Google logo).
Have you got any ideas what can I do now? Is there a way to fix it?
Try this: manually flash every partition from the stock ROM, including the userdata.img.
After flashing the userdata.img file, immediately boot into stock recovery using the power and volume buttons and perform a factory wipe.
Hey, thank you for your answer. Unfortunately after flashing every partition and factory wipe it still has bootloop. But before i did it, it wanted to charge my Nexus, I just plug USB and suddenly I realised that there is a Welcome screen! Everything was running good, WiFi was working... I turned on USB debugging and reboot it to check what happens, but it won't turn on again, now it is again with bootloop Any other ideas?

Accidently wiped /dev/block/sda, now won't get past boot logo

So i was trying to create a bootable usb for linux from my phone. I'm 90% sure my usb was mounted at /dev/block/sda, i did my "dd" command and unplugged the usb only to notice it was unchanged and my device was frozen. After powering off, i was brought directly to the download boot.
So first I tried flashing mu stock firmware, then i tried flashing Lineage Os with twrp. The boot logo just continues. I tried formatting with twrp, wiping cache with default recovery. I tried recovery. I just keep getting an error about EFS not mounting, but i thought that only affects radios/modems.
I don't know what to do Any ideas?
