Today I've updated from CM 11 (KitKit 4.4.4) to CM 12.1 (Lollipop 5.1.1). I made a backup, a factory reset and then flashed the latest nightly and Google apps. Everything was fine so I continued installing apps, restoring data etc. When everything seemed to be finished and the phone was as I want it to be, I wanted to make a new backup.
But now I can't enter recovery mode. When I boot the phone and press the volume button, the LED turns yellow as it's supposed to, but the screen stays black and nothing more happens. If I press the power button the phone reboots. So everything seems fine, the phone is working and I've got root access, but I can't enter recovery mode. I've tried to use ADB and fastboot but I can't connect to my phone so I can't flash a new recovery image. I can boot into fastboot mode with the LED turned blue but ADB stays on <waiting for device>. I've tried to update drivers etc and also tried another computer but with the same result so it seems there's something wrong with the phone.
In developer settings there's an option for CyanogenMod to update the recovery when flashing a new nightly - but I don't know if I can flash a new nightly when I can't enter recovery mode.
Any advices?
Update: With the CM Updater I downloaded todays nightly and applied it. The phone rebooted, apparently into recovery (yellow LED but still black screen). I left it in a few minutes, then it automatically rebooted and when it was ready to use, the nightly was updated.
So maybe there is some kind of recovery working on the phone - but I still can't access it...

Thank you, but as mentioned in my first post I can't get a connection to my phone with fastboot, so I can't flash a recovery image through ADB. I've also tried different apps to flash a new recovery like TWRP Manager, Rashr and Flashify but even if most of them reboot the phone into recovery mode, nothing more happens.
Is it safe to flash and older nightly e.g. the one from 8th August when I'm now running with a newer version?
Even if your answer in the first way didn't seem to help me, it guided me in the right way, and now finally it seems to be working
First I tried another computer. I thought fastboot really should be working and it did on the other computer, so the next thing is to fix a driver issue on my own - but that's another story... With fastboot working I flashed a TRWP recovery. The only difference now was that when booting in recovery mode the Sony text didn't disappear, but still a black screen and no recovery...
Then I followed your link, downloaded an older nightly and flashed boot.img, and now finally it seems that everything is fine.
So thank you :good:
Did you not use flashtool?
I' m back to stock..
Maybe later CM again

No I downloaded drivers from Sony and then flashed with ADB.
Hey guys,
i'm in trouble installing a custom ROM on a S4 Active (GT-I9295, Baseband IXXUDOB4, 5.0.1).
Flashed CF--Autoroot with Odin, no problem.
Then i flashed TWRP, Odin showed its green "PASS!"-message but i can't boot into recovery.
I'm well aware of the timing issue when doing the first reboot into a custom recovery, and i assure you this isn't the problem.
I tried countless times, after a while i installed ROM manager to try if i could flash the ROM file that way.
It installed another custom recovery -CWM- on top, and also showed up the TWRP recovery:
http://imgur.com/kSSiuld
Still, booting into any recovery does not work, neither from ROM managers menu or via any button-press combination.
When pressing vol up+home+power, the phone shows the blue "revovery loading"-line AND the red line *****ing about the root, but continues to boot as if it had been switched on normally.
I even looked for the ominous "install-sh" script in system/etc to understand why nothing gets me into recovery-
what the heck can this be?!
Did the same thing to S6 and S5 without any hassle, i'm stuck with this for several days now and i am running out of ideas.
Anyone...?
Not a very technical answer, but have you tried pulling the battery out for 30 seconds and trying again?
Yes we did, unfortunately, this also didn`t help.
Tried loads of things actually, still impossible to access that damn recovery
Hi all,
I have a big problem with my phone.
I wanted to try out Resurrection Remix on my phone.
I installed twrp-3.0.2-0-dogo.img with fastboot.
After reboot i saw the Teamwin logo and then i did a full wipe of everything, except SD Card (like i always do when i install a custom rom)
Then i installed Resurrection Remix M v.5.7.3.zip from sd and gapps, then wiped cache and pressed reboot.
No error with flashing, when the phone booted and i saw some logo's, took like 2-3 minutes and then the phone went off and started to reboot and reboot, had to take the battery off to let it stop.
Since then my phone isn't working properly, i tried to flash different kinds of stock roms with flash tool including wipe options.
No errors with flashing, but the phone still doesn't boot or it goes off after Sony logo then i leave the battery out for 10 mins or so then it starts and it looks normal, i can install aps, i can call, but the first time when i reboot my phone with this new install it's back to rebooting. I tried to leave my battery out for 10 hours but it doesn't help.
I tried to relock my bootloader and then unlock it again.
If i tried to install twrp-3.0.2-0-dogo.img it's going to reboot also, i tried airless or evomix kernel, then recovery starts but when i try to install a custom rom zip, and try to flash it my phone reboots after 5 seconds.
And now i don't know what to do anymore, so please anyone? help?
Thanks in advance!
did you try installing stock rom with flashtool ?
What was your android version when you first flash TWRP 3.0.2 recovery?If you are coming from stock lollipop then you should flash TWRP 3.0.2 (.228).Make sure you unlocked phone bootloader.Use advance clean in the recovery,select all except sd card and clean all.Then try flashing RR Rom again.Do wipe cache/Delvik after flashing RR Rom and before flashing GAPPS.

Yes, i tried atleast :
C5503_10.1.1.A.1.310_GLOBAL-LTE.ftf
C5503_10.6.A.0.454_HK.ftf
C5503_10.7.A.0.228_TR.ftf
And used all wipe options.
I used Emma tool, after that i removed the battery from the phone for 48 hours, then it booted the second time. I charged the battery and i left it like this for a few hours, then i tried to reboot but it went off after 20 seconds, tried to boot again but it goes off after Sony logo.

My version was CM 13 (cm-13.0-20160801-UNOFFICIAL-dogo.zip) that was working very well, but before i flashed RR i did advanced cleaning and i checked everything except SD Card and USB OTG and a factory reset and after flashing pressed wipe cache/dalvik and then i rebooted.
The phone is off now without battery. This Sony doesn't have recovery, buttons aren't working and they never did, i can only flash twrp with fastboot wich makes it only boot into recovery and then i used this to flash custom roms.
I only started to flash custom roms about a month ago because someone gave me this Sony ZR, i bought a new original battery for it but when i call on speaker there is some underwater bubbling sound and i also wanted marshmallow and i hoped this may fix the bubbling sound, with CM 13 the sound was already better but didn't fix it completely.
TWRP won't let me flash anything anymore, it's starting to flash but after 5 seconds it reboots back into recovery.
Edit: Is it possible that there is still stuff in the RAM that is causing problems?
Edit: I thought i'm going to this phone another try. I installed twrp-3.0.2-0-dogo.img and it boots, also this version didn't want to boot anymore but now it does. I wiped everything, also SD Card, i checked everything is empty. Before i couldn't wipe my SD Card anymore and in Windows all files showed double and i couldn't copy files. Going to charge it first and think about what i want try to flash. Wipe cache/dalvik and then flash gapps is a good idea.
Edit: it almost charged now, when it charged i will remove the battery again for the night, i will decide later what i'm going to do.

Someone maybe played with your phone in underwater to cause bubbling sound.I don't see any hardware problem in your phone.You maybe did something wrong or anything else that your phone behaving like this.Listen,You first flash a stock rom.Lollipop would be better because you can flash flashable twrp 3.0.2(.228) via flash fire or flashify app.I once tried flashing twrp img through fastboot and it caused bootloop.So I always use flashable zip.Fastboot for emergency.And try to reformatting your system pertition.I hope this will work or you'll need expert developer to help you.Maybe Daedroza can help you if my sugg. don't work.

The bubbling sound is a known issue with some Sony smartphones, on google i have read more stories about this problem, not only zr but also other Z models. The problem is caused by the second mic i think, if i use loudspeaker when calling and i lay the phone on the back the sound is much better. I saw on other thread about this, http://forum.xda-developers.com/xperia-zr/help/disable-mic-t3434997
On YouTube you can find many movies about this, for example https://www.youtube.com/watch?v=fC6JbuQJ_gg
It's really annoying for the other person to hear these sounds when you are calling. They need to listen very carefully to understand you, but it's only when you call on speaker.
When i wanted to flash a custom rom for the first time i wanted to do this with apps on my phone. I rooted my phone with kingroot and used an app to check if the phone was really rooted. I installed twrp app and tried to install recovery but it gave an error. I tried to install recovery with Flashify but then it says that the recovery partition is not present. When i try to flash with Flashify it says it's going to reboot into recovery but then the the phone boots like normal. The only way for me to get a recovery on the phone is just flashing with fastboot or using flashtool. Doomlord kernel and XZDualrecovery don't boot, only twrp is working.

First of all change the kingroot with supersu.Kingroot root access control not so stable.Download selinux mode changer to set in permissive mode.If you are at LP version,twrp app won't install recovery or support it.flash twrp3.0.2(.228) via flashify or different flashing app.selinux permissive mode will let you to go to recovery mode.By the way,xzdualrecovery is for locked bootloader and should boot without any problem.I don't know it will work on unlocked bootloader or not.So try your best what I have told and this is all I have to share from my own experience.

I flashed the latest Lollipop and it's back to rebooting, i see the sony logo and before it says powered by android it goes off. I removed the battery again, i will try to root the phone and use selinux mode changer when it's booting. It wil take atleast 12 hours without battery before it boots.

Is there any problem with your phone?Did you experiment your phone too much?I don't get it,why after flashing stock rom via flashtool gives you bootloops if no error showed up while flashing!!Is this your battery problem?And I think so because few months ago my phone battery heavily damaged and therefor It don't charge and my phone didn't bootup but bootlooping.I first thought it was my mistake to flash rom incorrectly.So i had to flash stock rom via flashtool to go back to normal but unfortunetly PC don't recoznige my phone not even fastboot.I was worried and couldn't do anything and went to service center,they changed the battery with new one and my phone comes to life again.Mainly this was for my local charger fault.it also damaged in that day too.SO brought a orginal sony charger.But you said you brought a new battery too then how come you face bootloops.well if there is no error message shows up I can't help you with anything.Only better expert member can help you.By the way you can collect log via adeb fastboot if your phone fastboot mod work.
Here is the inst:
1. Install the Android Debug Bridge using http://developer.android.com/tools/help/adb.html
2. Instructions on installing Android Debug Bridge are located here:
http://www.howtogeek.com/125769/how-to-install-and-use-abd-the-android- debug-bridge-utility
3. Run the following commands:
“adb logcat -c" (This clears the logs.)
4. Reproduce the issue.
5. Then, run the following command to capture the logs in a file:
“adb logcat -d > Name_of_Log_File.txt"
maybe it will gives some clues what is happening.

I tried my old battery and it boots, already booted up 3x times. I never thought it maybe the battery because it's only 2 months old. Thanks so much for your help.
I tried to install recovery with selinux permissive mode and flashify but i stil can't install recovery.
It says: Partition not found, your recovery partition couldn't be found. You won't be able to flash recovery images. You can stil flash zip files.
I don't think it's possible to have recovery on this phone, atleast not the normal way.
Edit: I flashed RR and it's working fine. I'm so happy it's working again, i never really used this old battery but i think it's not so bad at all. I only lost 8% battery with flashing and booting RR. I never really thought it was the battery because it was charging normal, i used it for 2 months or something without problems.

If it was a battery problem then change it or carefully use it.And the error you are facing is because the latest flashify has some bugs.But now as you are already using RR MM rom.You can download twrp app and use this app to install recovery.

I tried to install recovery, flashify hangs all the time, twrp app gives an error when i try to install recovery and flashfire says there is no partition for this image. I thought i'll do a factory reset in RR and when the phone rebooted i saw twrp. I tried with pressing the buttons when booting but no luck. I used reboot into recovery option and it worked. This is the first custom rom that gave my phone recovery.
I will throw the battery away and use the old battery, i can always buy a new one later.

OH!So that the old recovery occupied all the recovery partition space that you are unable to install twrp recovery.But old recovery should be replaced by new recovery,that's strange.well I don't know how did this happen but don't use fastboot to install recovery or anything else,It's for emergency.I'm not fully familiar with fastboot though,I tried once before and caused trouble. I hope your troubles are gone now.

My phone don't have any partition recovery, i tried 100x times with stock rom to boot recovery, with buttons, with apps that boot in recovery. I do have recovery with RR rom, but it's not in the recovery partition. I tried Tesla, CM 13, XOSP but still no recovery. I tried to boot recovery with all roms, but it doesn't matter. It's fine now, been playing a bit with RR and it's a nice rom. Thank you for helping.
Installing TWRP was one of the first things I did when I got this Lenovo phone.
It worked like a charm, I pressed the Volume Keys and the Power button simultaneously and voila! TWRP opened. I was planning to install a custom ROM, so I decided to backup my device, just in case something goes completely wrong. I backed it up, then tried to move the backup from the /data partition. That went kinda wrong and for some weird reason TWRP didn't do anything but show this loading bar on the bottom of my screen.
Since TWRP was being unresponsive, I decided to remove the battery from my phone.
When I tried to access TWRP again, to my surprise, it was gone. The stock recovery appeared instead. I tried reflashing TWRP using both SFP and ADB/Fastboot, and even though the transfer was successful, the Lenovo recovery was still there. I booted to Android and saw that the "OEM Unlocking" option was disabled, even though I had enabled it. I re-enabled it, tried all the things I mentioned before and I got the same result. I opened up Android and.. OEM Unlocking got disabled.. Again.
I enabled it, yet again, tried going to fastboot, where I tried unlocking the bootloader. FAILED! I also tried side loading SuperSU.zip. FAILED!
As a last resort, I used Kingoroot to root my device, and to my surprise it worked.
I still can't seem to be able to flash CWM/TWRP, though, and I would like to install Xposed. SuperSU is also a necessity for me.
TL;DR I can't flash a custom recovery even though I could, Kingoroot worked for me, I need to get SupeSU, Xposed and a custom recovery. Side loading/Flashing using ADB isn't working, OEM unlocking gets disabled every time I reboot my device.
Now that you are rooted, i would suggest you to try 'flashify' and check if you can get your twrp working again. I still doubt it would, since you said you werent able to get it installed through fastboot before, but first give it a try.
When you confirm it working just flash the supersu zip using whichever method you like.
Hello Friends,
Yesterday I was chatting on whatsapp and suddenly my le2 restarts, and then a blue splash screen appears and device keeps on booting,
hence I went to recovery and clear the data, but that also didnt help me,
Then i flash the 13s rom via Flashone 1.9 then also same problem happens, sometimes it went to optimizing apps 3 of 4 and again restarts with blue LED, i were unable to switch it off,
after draining the whole battery I keep mobile to charge but now it is not charging, it only showing Red Solid LED Continuously.
Now I am also Unable to boot into recovery or fastboot mode.
I again flash the stock 13s rom via flashone 1.9 , i got success msg but then also mobile is not booting nor it is charging.
Note: I am on complete stock rom on locked bootloader, never unlocked or rooted, used as come in box.
Please give me a solution on this, I have searched everywhere but not getting any solutions.
Thanks in advance
Try to check your USB cable, most of the time charging issue is due to cable

Cable is ok. I have another Le2 and it is charging with that cable very well
I am facing same problem. How you solve this issue? Blue led blinks after flashing any rom and bootloop.

I also have the exact same problem. Phone started rebooting as soon as it booted up. Somehow i managed to unlock the bootloader, but to no avail. Can't seems to find any rom which can boot up. So practically i have a bricked device with trwp. Formatted the system and other partitions with twrp, flashed many roms. Still the result is same. Bootloops.
Hi,
try to to reimage your phone with QFIL from this site:
https://www.techpoison.in/2017/12/how-to-flash-letv-le-2-x526-stock.html
I downloaded everything from there, QFIL, Sparse image and drivers. My phone was bricked, but its working normally now. After you flash the image your phone should charge normally, just try to boot it up. In my case i had issues with baseband, not detected, no sim function and no wifi and phone was restarting each 3-4 minutes, but it was operable. Basedband issues can be solved by hard reseting the phone and updating it to 21s using the local update, just put the 21s stock renamed to update.zip to internal storage and run system update. When you get the error - APK missing, just boot it up again and retry the local update, should work fine the second time, i just deleted the update.zip and put back again and ran the update.

Flash the 21s bootloader + modem, one ZIP file, should work fine. Not sure what ROM did you install last time. You can give it a shot with with MIUI 10 - its nougat.
I had similar issues, see my topic, maybe it helps a bit.

Brother same thing happened to me, a week ago. I cant say about your problem but my problem was due to faulty power button. Actually due to that reason my phone actually kept restarting itself. It showed red light blinking while charging and wasn't able to bypass the optimizing app screen. I also thought it was a software issue but actually it wasn't. I spent about 2 hours figuring out what the actual problem was. The problem was: As we know when power button is hard pressed for about 10-15 seconds it reboots itself.
Although the repair shop guy didn't put new power button but he added a tiny piece of paper in between the power button and body housing to prevent the issue and voila the problem was solved.

https://www.techpoison.in/2017/12/how-to-flash-letv-le-2-x526-stock.html
I downloaded everything from there, QFIL, Sparse image and drivers. My phone was bricked, but its working normally now. After you flash the image your phone should charge normally, just try to boot it up. In my case i had issues with baseband, not detected, no sim function and no wifi and phone was restarting each 3-4 minutes, but it was operable. Basedband issues can be solved by hard reseting the phone and updating it to 21s using the local update, just put the 21s stock renamed to update.zip to internal storage and run system update. When you get the error - APK missing, just boot it up again and retry the local update, should work fine the second time, i just deleted the update.zip and put back again and ran the update.

Flash the 21s bootloader + modem, one ZIP file, should work fine. Not sure what ROM did you install last time. You can give it a shot with with MIUI 10 - its nougat.
I had similar issues, see my topic, maybe it helps a bit.

Hi, Thanks. I actually did that first, flashing through qfil the same rom. it helped me to go to settings after umpteen attempts to go past language selection screen, and i was just able to oem unlock and enable usb debugging (actually after a 2nd partial failed flashing). the phone kept freezing within seconds of booting up. Now After i unlocked the bootloader and installing twrp and flashing many roms thru twrp, i am still having the same problem of booting up and freezing at start-up. cant flash again through qfil, as i will again loose the unlocked bootloader and twrp.
At least , now i can try different roms to see which can unbrick it. last one used was the twrp flashable rom based on eui (small eui by aurel) but it also freezes on language selection screen or beyond.
I am running out of ideas, lets see.
2nd partial failed flashing? any issues during the flash process? i had some issues when i used usb 3.0, 2.0 worked fine for me. If you have also charging issues stay in twrp and let the phone charge properly, its slower but should work fine. You can try to flash the 21s bootloader with modem, maybe it will boot properly. But try it only when you are able to enter the fastboot mode, longpress volume down and power for 10-15 seconds, if that is working you should be able to flash twrp via fastboot and you can experiment a bit. Try to find the chinesse twrp 3.0.2.0 and try to flash the stock 21s version. Should be also an image file, in standard twrp go to install - image, after selecting the image file click on recovery and install, after installation go back, reboot, recovery. Copy 21s to storage, wipe data, cache, dalvik and flash it, chinesse twrp will skip version check and will let you install the stock image, after install reboot but click on do not replace recovery button - this will keep the chinesse twrp installed.
If nothing helps it can be only a HW failure, maybe the power button, try usb 2.0 port during the flash process, i had issues with 3.0 on my pc, if that doesnt help.try a different cable, no more suggestions, sorry.

My phone has been flashed multiple times by qfil method. And always it hangs at initial setup (so it boots up, but hangs at language selection or further up screens, before setup can complete and launcher could be loaded).
While trying to flash again with qfil once it stopped at 25 percent (because the battery went dead). Charged the battery and booted up the phone, and i was surprised it booted up. After 2-3 attempts i was able to reach the launcher screen and immediately enabled developer options and oem unlock / usb debugging. Only had few split seconds to do this and the phone froze again. After that i installed twrp and hence treying different roms. Most fail at setup.
Just tried MIUI 9PRO ROM. It also froze at setup multiple times, but once i was able to complete the setup and miui launcher is up , but it reboots or turn off the phone just after that. So cant do anything with the phone. Unsure of whether a newer bootloader will help in these freezing issues as i have been able to boot up at least in some roms only if for few seconds. Will try to tinker the settings of miui rom (if the phone let me do it before freezing/hanging). Lets see. Thanks for suggestions. More suggestions welcome, because i am still unsure weather this is a software or hardware related problem. I am guessing that it may have something to do with Google security as earlier i was getting msg that phone has been wrongly resetted and needs to verify with Google (but i couldn't get a chance to use the same account, as phone kept freezing at setup).
Did you fully charge the battery, if not let it fully charge in twrp. Flashing the roms in twrp works everytime or do you see any errors? Before you flash anything disconnect the usb cable.

Try to flash the 21s bootloarder with modem, one zip using twrp. Go to fastboot mode and wipe modems. fastboot erase modem1st fastboot erase modem2st. Put the phone to flash mode and reimage with qfil. Before you do it write down both imeis, you can find them also on the original package on the backside. Also try to remove all sim cards from the phone and try a different cable. If nothing helps, hw issue, maybe the power button mention earlier in this thread.
After reflash skip everything at setup and reset phone to factory defaults. OEM is already unlocked, you dont have to do it again.
I have charged the phone fully before any flashing after that error. I can flash the phone through twrp without any error msg. The phone boots up most of times in various roms but hangs at or after the initial setup screens show (like language selection etc). Flashed the modem+bootloader, success, but it showed bootloader version as 20s (not 21s). Tried the commands u mentioned to erase modems, it say error failed, no such partition found. I had checked the partitions with parted and 56 partitions are there including the modemst1 & 2.
Now re flashed via qfil , did as advised but again the same problem of hanging / freezing at or after initialization screens of various roms.

Yeah sorry i screwed the command its fastboot erase modest1 modemst2, my bad.
Just now i was able to complete the initialization (setup screen) of sparse image india rom. I can reach the launcher and settings for few seconds before the device freezes or reboots.
So the same problem , with which i started, the only good thing is that i have been able to set oem unlock to on, so that i can flash trwp and various roms (but all fail with the same freezing issues)

So you erased modems and reflashed with qfil right? If so i assume its a HW problem. Try the fix with the power button, i ran out of ideas
Last thing which can help maybe: https://www.youtube.com/watch?v=LH3VOIlLfvo&t=135s
Download 21s stock image + the chinesse twrp, links should be under the video, i think so, or look somewhere in the forum for new links. Try to reflash the 21s, some people reported that freezing issues were gone after installing the latest EUI. Basically you can do the same after QFIL reflash but you need enough time to copy the ZIP file as UPDATE.ZIP to the internal storage and run the local update via setting, system update and local update, i hope that TWRP will work for you, just follow the video tutorial.

Did that also, the same problem. The phone freezes after the os is booted. I was wondering what is that isnt touched by flashing ( in download mode or fastboot mode or through twrp). I may need to tinker that. The roms are all fine in the sense they all stop at the same points. Something in the phones partition, which isnt touched by flashing? (There must be, as i flashed with qfil, the oem unlock remains, the bootloader didn't lock, and it remains unaffected by re-imaging)
Try this, maybe it helps:
